Major Favtors - Essay Example In that case, the accounting practices in China focus on both the fair presentation of financial position and a conservative presentation. The reason behind a fair presentation is to meet the various needs and requirements of the stakeholders and the capital market. The conservative approach is targeting the banking sector, which has a direct access to financial information (Central Intelligence Agency). (b): Legal system – the legal system in China is coded. Coded laws seek to, exhaustively, envelop the existing laws and preserve their implication to match that of the time it was coded. For this reason, the Chinese accounting practices are highly, rigid, prescriptive, detailed and procedural. This kind of legal system requires that the national law regulate the accounting practices. For that reason, China engages in the preparation of two sets of financial statement. That is, the rigid and the adaptive type, to comply with different types of legal systems (Central Intelligence Agency). (c): Taxation – the system is linked to reflect the legal system. In China, the national laws regulate the taxation practices. In this case, the accounting and the taxation process are the same (International Federation of Accountants). (d): Political and economic ties - the basis of accounting practices is influenced by the external forces due to international relations. China has strong political and economic ties with Japan, whose legal system is codified. The ties have greatly influenced China’s financial reporting regime (International Federation of Accountants). (e): Inflation – the changes in the rate of inflation affect the commodity prices in countries. The financial figures should reflect the level of inflation in a country. However, in countries with a low rate of inflation, like China, the reported accounting figures rarely reflect the rate of inflation (Central Intelligence Agency). (f): Level of economic development – the economic development in

Why did the Macmillan administration chose to opt for EC membership Essay

Why did the Macmillan administration chose to opt for EC membership - Essay Example The treaty worked to free the movement of goods, services, capital and labor between its member nations. In 1960, as a result and in an attempt to destroy or absorb the proposed EEC common market, the U.K. and Sweden created the European Free Trade Association (EFTA). EFTA was an attempt to conserve Britains role and economic position which was remotely attractive to major Western European states. In 1963, the Prime Minister of U.K., Harold Macmillan, decided to change Britain’s foreign policy towards the European Community and attempted to join EEC. He suggested to unite the member countries of EFTA with ECC to incorporate all of Europe but France vetoed further talks. Macmillan saw that the exclusion from EEC was damaging to Britain both economically and politically. The following sections will presents the reasons why Macmillan’s administration chose to opt for European Community membership. To maintain Britain’s world role in the face of economic enervation, Macmillan did not follow Anthony Eden’s policy of reliance on the United States. He evolved the British strategy to include a new relationship with Europe to complement the increasingly unreliable American proxy (Ruane & Ellison 2004:1). Eden’s administration saw that the maintenance of the British extended empire placed a burden on the countrys economy beyond its resources. They manipulated a foreign policy to ensure that the country’s strength was equal to its obligations. They aimed to persuade the U.S. to assume burdens of an international defence organization while retaining for Britain as much political control as possible. This was the only solution Eden came up with to spread the burden of two major obligations for which Britain currently bore primary responsibility. In January 1957, the Suez Canal crisis brought down Prime Minister Eden and caused his resignation to be succeeded by Harold

The Objectives Of Clinical Management Systems Information Technology Essay

The Objectives Of Clinical Management Systems Information Technology Essay CMS stands for Clinical Management System, including the information integration, inventory control, data processing and tools for medical data exchange. Generally the major user for CMS are physicians, and consist of laboratory information system (LIS), radiology information system (RIS), picture archiving and communication system (PACS). 1In medical fields, the application of new CMS mainly develops in the following stages. Automated medical record (AMR) is mainly used for the automation in medical data processing from paper into e-format. Electronic medical record (EMR) ensures a good communication for paperless and image exchange and sets up foundation of medical terminology. Electronic patient record (EPR) ensures the interoperability networking for the data exchange between CMS or other parties by using a single and standard format. Electronic health record (eHR) sustains the medical decision support system. In the medical support system, it conducts data mining skills from getting multiple data from multiple databases to assure the correct medical decision. Recap above stages, the applications of CMS are useful in medical filed. Objectives Due to the following objectives, our team suggests Town Health co Ltd to implement Clinic Management System (CMS). Increasing business opportunity; Connecting medical record with Hong Kong Government regulation standard; Exchanging medical data with Hong Kong Government centralize database. Company Background Town Health Co Ltd. (The Group) Established in 1985, the group has adopted the managed healthcare model to provide high quality and affordable medical services to our corporate clients. THMN has a full range of medical services, including General and Specialists Services, Dental Services, Physiotherapy Services, Laboratories Imaging Services and other auxiliary medical services. The Group has well developed and became one of the largest healthcare services providers, with about 30 medical clinics and specialist outpatient clinics, in Hong Kong. Company network Figure 1.1 http://www.thmn.com.hk/our_locations.asp Company Workflow The Group was operating a standalone medical management system over 10 years. Many problems occur throughout their daily operation. The basic operation workflow is shown as below figures 1.1. Diagnosis New Patient Registration Consultation Medical Record Transfer to Hospital/Other films Treatment Figures 1.1 For our daily operation, a new patient is required to fill in a registration form for his / her personal information in paper format. Then the duty doctor consults and examines the patient based on the background and situation at that moment. The paper medical record and real time observation by the duty doctor will be used as tools to support the diagnosis of the patient. Finally, the staff or nurses will input the finalize treatment formulated and medical record into the existing medical system. Five Force Analysis For The Group Suppliers Industry Competitions Buyer Potential Entrants Substitutes Threat of New Entrants There are many new entrants in Hong Kong healthcare services industry. It is because of the rapid changing of economical scale, such as new investments from PRC. Threat substitutes Since the market demand is changing recently, many different professionals are willing to join together and run their business to provide a 24*7 (24 hours with 7days) services. Besides, they combine their services into a single business firm, such as Chinese medical services, Dental and out patient services. Therefore they can share resources to reduce the operating cost and increase the revenue. Bargaining power of Suppliers Most of suppliers ally their product price due to the increasing price of most original materials. For a healthcare group, they are required for lots of inventory, like drugs and medicate equipment. This is a main reason for their high operating cost. Bargaining power of Buyers The Government regulation was release as benefit to all Hong Kong elders such as health care voucher, eHealth medical record sharing system, and etc. Industry Competitors There are many strong competitors with increasing and steady revenue. Moreover, most professionals quit their job in public sector (Government Hospital) and join the joint venture of healthcare group to start their own business. SWOT Analysis for The Group Strength The group is established for over 25 years, it is a well-known health care services provider with confidence in providing quality services. A wide spread of clinic coverage is convenience to all patients in Hong Kong. The medical management system assists on keeping patients records that ensures the efficiency on daily data processing. Weakness Performance of existing medical management system becomes slower due to the increasing size of data. Increasing numbers of patient records reduce the performance of accuracy. Thus, many errors were found in daily operation which influences the efficiency. The system will become a bottleneck of the Group for the business expansion. Opportunity Modernize on computer system provided a better management on patients data and prevent error to increase efficiency on operation. Also, connectivity to Hospital Authority (HA) and insurance companies database can get advantages on increasing revenue and convenience of data exchange for the Group. Treats The medical industry competition had a huge impact to the Group due to the decreasing market share and revenue while the running cost for equipment and drugs is increasing. Research Methodology Research method Interview for analyzing the current problems The aim of the interview is gathering information about the understanding for the current system and its process. Our team conducted the interview to narrow down the problems one by one. Web survey for capture the industry strategy Due to the rapid change for the market, this survey is aimed to get the most common strategy for our team. Data Gathering This process is mainly used for identify the existing operation problems through the interview with the company partners, managements and customers. Peoples interviewed: Partners Project mangers Customers The questions for Partners What is your corporate vision and mission? What is your corporate development target in long term / short-term? What is your development strategy in long terms / short terms? Do you agree the change of Hong Kong market decreasing revenue of your company? How many resources had been spent on your strategy development projects? What is / are the existing problem(s) that your company is facing now? And how does your company fix it? The questions for Project Managers How do you carry out the CMS? How long do you planned for your project schedule? How the CMS fulfill the development of your company that you had mentioned before? How many resources had been spent on your strategy development projects? The questions for Customers What service(s) do you mainly used in Town Health Corp? Do you comfortable with the current system of Town Health Corp? 3 Do you have any suggestion(s) for Town Health Corp? Through the interviews, our team recognizes the mission of health care group is providing a comprehensive healthcare service. The short term planning is to develop an effective clinical management system, while the long term objective is to build up an exhaustive service for customers, such as medical decision support analysis. To achieve the short term and long term objectives mentioned above, we have to improve: The duties schedule of physician Communication channels with other insurance companies The inventory control and allocation Standardization of e-health medical record Survey result All interviewee thought that the eHealth is useful as it answered them many questions and as a platform to communicate with others. Whats more, over 80% clients having discussion with professional after a year, which is dangerous if they didnt take annual body check. Almost 80% clients thought the Clinical management system should be connected into Hong Kong centralize database. Due to the elderly dont know how to use the high technology (e.g. computers), thus the respondents refuse to use it. There are only 20% of interviewees think that the Clinical management system cant be effectively the diagnosis processing. Almost 80% of respondents has been used the clinical management system, especially most of them used the Google one. The respondents all are educated above the primary school and most of them are in the age group of 30-39. Values Identified from Interview Objective Schedule Management Insurance interface Inventory control e-medical Record The duties schedule of physician Communication channels with other insurance companies The inventory control and allocation Standardization of e-health medical record Problem Definitions The Group was operating a standalone medical management system over than 10 years. However, there are still many problems occur during daily operation. Data formatting out of date The existing medical system was developed in 1989. All clinic offices were allocated a standalone workstation for operating medical system. The medical system database was developed by FoxPro which could not conduct data mapping with other new technology like Microsoft SQL server, MySQL server. Hence each medical system was all recorded year by year until present. Suffering in medical claim to insurance company Every time when different insurance companies transfer some patients data for inquiry, the staff needs to input the patient data one by one manually in order to get the corresponding data from the database. After all required data have been extracted from the database, the staff needs to enter the corresponding data to different systems that provided by insurance companies. Sometime if the data from insurance companies could not match with the database, the staff needs to notify the insurance company for amendment. After receiving the update data, the staff needs to do the inquiry all over again. Cannot manage resources on inventory Existing medical management system can only handle patients records. Inventory of the Group is recorded by using a logbook. Using of pen and paper cannot fulfill the services standard nowadays. That is not a flexible and efficiency way to keep track and monitor inventory, especially for a medical group which owned over thirty clinics. Manpower that used on inventory is also become a challenge on management and costs. Cannot manage customers appointment effectively Many clinics handle their patient appointments by using telephone bookings and marked on the notebook. However, it always has the contrived mistake, for example, marked down the wrong name or contact number. Sometimes the patients need to wait for a long time to check the appointment time or the medicine stuffs. Furthermore, the doctor may not stay in one single clinic; it is inconvenience for the customers who want to consult the same doctor. Based on problems above, managements decide to carry out a new Clinical Management System (CMS) to replace the existing one. Our learning area: Electric Medical Record, Interfaces with Insurance Company, Inventory Control and Book appointment with web interfaces. Successful Stories 2The Hospital Authority (HA) of Hong Kong 3The Hospital Authority (HA) is one of the successful case of implement CMS in Hong Kong. HA set up 15 Chinese medicine outpatient clinics (CM Centres). These 15 CM Centres are served with a fully computerized Chinese Medicine Information System (CMIS). CMIS is developed by HA for managing a large amount of clinical information. The CMIS is aimed to the support for patient administration (example, appointment, registration and payment), clinical modules (example, diagnosis, consultation notes and prescription) and pharmacy management. It can also treat as a platform for data analysis, planning and researches. The Integrative Medicine Information and Research Manager of HA, Tat Tse said, the system can reduce errors and enhance risk management, for example, the emergence of drug incidents, we can trace the patient and arrange examination as soon as possible. 4Union Hospital in Hong Kong Another successful case for CMS implement is Union Hospital and Union Hospital Polyclinic. Union Hospital was established in the year 1994 while Union Hospital Polyclinic (Tsuen Wan) went into service in January 2007. Hospital and polyclinic have an advanced Customer Management System to provide comprehensive patient data and flexible registration service. It is convenience for the clinic and the hospital to access the patient information and medicine history. It is also expediency for the patient to choose the venue for having the follow-up care thought out the network of Union Hospital. Proposed Solutions With the reference to the above successful cases in Hong Kong, the main purpose for the CMS is easy to deliver medical data. It is a centralized system to control and share the resources, like medical information, to related departments, like Pharmacy, Laboratory and front-end clinics department. Besides, CMS can be synchronized all the medical data to both public and private hospitals and other CMS. A brand new CMS become an important milestone in the IS strategy development. Inventory control To improve the inventory control, the implement of inventory control system is required. It can increase the flexibility and efficiency. The new system will include inventory monitoring, stock transfer, out of stock alert and reporting, and other function like expiry date reminder and search. These functions are the daily tasks which are operating manually every day. The implement of new system can help to reallocate manpower to other tasks. Schedule management The system will renew the data periodically. Old records of patients will be found easily. Clinic staff can handle the patients records and the appointments by using an easier way. Insurance interfaces The system can get requests from different insurance companies and reply those insurance companies automatically. A summary report will generate for checking every day. This can save the manpower of processing insurance companies request and prevent missing or wrong information exchange. E-medical standard Since all the new medical data should be matched with international standard, developers change all the new medical data into  [5]  HL7 format. HL7, an international standard medical system, can exchange data with other systems, which will be the main trend for future development. This action may cost lots of resources in transferring to the new CMS, it is still certainly required for the long term strategy of health care industry. Physical Architecture This section describes the physical architecture of the System. The below diagram shows the physical architecture of the System. The CMS is constructed in 3-tiers web based architecture, which includes web server, application server and database server. Web Server The Web Server will be the primary entry point for all users to access the system. All user activity will be limited within the Web Server. Application Server The Application Server will serve the validation process and the using of the stored data in the Database Server. Users will access these functions through the user interface located at the Web Server. Database Server The Database Server will be the central repository of all data. These data will be using for validation purpose. Software requirements Internet Explorer 5.5 above Java web starter 6.0 above MySQL 10.0.1 above Tomcat web server 6.0 above Hardware requirements IBM X3250 M2, Xeon E3110 3.0GHz/ 1333MHz (DC 65w 6MB L2 cache), 8GB 667MHz SDRAM, 160GB Hot-Swap SATA HDD Tape Drive [Prod Servers] IBM Tape Backup Drive Juniper Netscreen-5GT CableCat5 and Cat6 KVM 1U 15 LCD Monitor w/ 8-port PS/s Solution Budget The solution estimated project costs are shown as below: Items Estimated Costs (HK$) 1. Project team staff/development costs# 500,000 2. Project office set up and running costs including rent, telecom costs, mail/courier, etc. 100,000 3. IT costs including PC, software, printer, fax, LAN set up, etc. 100,000 Grand Total 700,000 Workflow of new CMS E-Medical record standard formats (Health level 7) apply in CMS First of all the medical record (HL7) run across multiple module of CMS, the example shown the workflow of e-medical Record useful in multiple modules of CMS. HL7 is mainly use for data exchange in different multiple module. Such as a single medical record it can be data exchange to doctors in clinical departments then transfer information to other lab departments then the lab result can be generate the medical decision support lab test. Finally the doctor can be made the medical decision and prepared the consultation result. The medical can be claim to insurance company directly for patients. Workflow of appointment in CMS The client calls to book the time with the right doctor. The clinical nurses mark down the information of the client and find out the clinic data from the database. The nurse call to remind the client and confirm the booking. When the client comes, then the appointment is done. Phone in to clinic Mark down the client information Call back and remind the clients Appointment done! Workflow of inventory system 1. Medicine, equipment or office supplies delivered to warehouse, information and amount of each product will be updated into the inventory system 2. Staff in clinics will place order for different items in the inventory system, delivery will be arranged. For some critical items like life-saving medicines, order will be automatically placed once the amount dropped to preset minimum quantity 3. Items delivered to each clinic from warehouse Workflow of Medical Claim Enquiry From Insurance Company Insurance company send medical claim request to CMS, CMS will retrieve data automatically from database and return diagnosis result back to that insurance company. Implementation Schedule The following is the paramilitary schedule of the proposed plan: Date Major Milestone Month 1 Launch of the CMS Project Proposal evaluation Month 2-4 Project Initiation User Requirement Collection Mouth 5-6 System Design and Analysis Procurement and Installation of Hardware and Software Interface with external systems Mouth 7-8 Program Development Mouth 9-11 User Acceptance Test Documentation Training Mouth 9-11 User Feedback Collection User Feedback Analysis System Design Revision Mouth 9-12 Program Modification User Acceptance Test Documentation Training Phase 2 Live Run Conclusion Durng the study topcis,all of us exploer our eye on Hong Kong Helthcare business operations.Due to the market change from previous, Hong Kong became stanadardation with international.The government of HKSAR become the leader role on electric health care stanard and regulations. Hence the team regonzine the implementation of cinical management system just the begin electric health care stages. All the industry stakeholders become more international standardization in future! Project Self-evaluation The study of CMS and its functions team completed the target because we can learn Healthcare knowledge during the project. The project management works are fine and the team conducts many discussion points during preparation. Finally I inspirit our teamwork steps until project closure. Tommy Wong @ Middlesex University 2011 During this project, I got the chance to explore and learn about the medical industry, and the relationship between information technology and medical and how they benefit each other. In my own findings using information technology in medical industry especially the outpatient services, is still in a preliminary stage, which mean more I.T. elements can be used to enhance the perform, more efficiency and profit can be archived. Simon Wong @ Middlesex University 2011 During this project, our division of labor is very balance. Everyone tried the best and put many efforts on it. I in charged the parts of findings, included the survey result, interview result and others. However,  some difficulties  encountered in  investigations, for example,  many respondents were  not sure  what  is eHealth, or  send the mail to people have not reply. I think our team spirit is good. But I should do the project more actively. Whats more, after my self-evaluation, I think my work is fair effective and efficient, due to the fair English grammar, I might need the others group mates help to proofread. At the same time, I think my time management can be better, because of my delay, the schedule of work might postpone. I hope I will do it better next time. Eric Pang @ Middlesex University 2011 Medical topic is a totally new topic to me, but to deal with different industries and departments is one of characteristic for Information Technology. Though this project, my skill for handling an unfamiliar topic is improved, which is equipped me to be an Information Technology professional. In this group project, I responsible for research on medical field business model. I found that even in a field of professionalism, the competition between companies still very great. Therefor price war is not a best way for them to increase the revenue. Before this project, I truly believed that price war is always a way to help companies to develop their business, but now I understand that with the information system support and re-engine the process flow, the company still can increase their productivity and achieve the target of increasing revenue. After this project, doing the analysis on the company background and market background become more and more import to me when designing solutions. This is the first time for me to handle an unfamiliar topic, medical health care industry. I had spent a lot of time to search information and catch up the schedule of my teammates. By having thIs experience, I am sure that I can do better for next time. Ben Wong @ Middlesex University 2011 Appendix 1 Interview Questions with Answer Dr Joseph Lee, Partner of Corporate Development Town health Co Ltd 1 Feb 2011 Dear Dr Lee, We are a group of year 3 undergraduate students of Middlesex University, School of Engineering and Information Sciences. As part of our final year studies, we have been asked to contact and interview a strategic manager on a topic related to the use of Information Technology and Information Systems within the organization. The focus of our approach is to look at the strategic reasons why a particular configuration of IT/IS functionality was adopted assuming that competitive advantage was the prime focus of the implementers. The topic we have selected is Clinical Management System implementation for the chain health care group. We approach you because we believe that our topic represents an important strategic use of IT/IS within your organization. We are requesting a short interview with an appropriate strategic manager within your organization. We should only take a short amount of time at your convenience. However, we do have a deadline of early December for this part of our work. If you are available to help, please reply me by email to [emailprotected] Thank you for your consideration of our request. Yours truly, Tommy Wong Attn: Dr Joseph Lee, Partner of Corporate development, Town Health Co. Interview Questions 1. What is your corporate vision and mission? Our group mission is grouping up all the clinic services to provide a comprehensive healthcare place to the public. 2. What is your corporate development target in long term / short-term? Long -term: Our corporate development target will be emphasized on the elderly mansion. We can provide the periodically body check as elderly easy to have the elderly ill. We would like cooperating with them by contractual in the future 5 years. Whats more, they will enjoy the discount by joining our group elderly program. We hoped that we can have over 30 elderly mansion join us. Short -term: Another our consideration is the doctors who wanted save the rent. They can use the place that share with other doctors, thus they still have their own clinic room but share the rent and human resources. It is because we want to keep increasing our shops (about 10 /year) in different area in HK to enhance our brand image. 3. What is your development strategy in long terms/ short terms? Increase the shops of Town Health is the one of the promotion plan. It increases the brand warranty and customer trusting. When the demand increases, the supply should be increased too. In long term, Town Health has to use personal selling to explain the services to the elderly mansion. Therefore we will recruit more sales to demonstrate our job to the elderly to increase our professional image and increase the corporate opportunities. 4. Do you agree the change of Hong Kong market decreasing revenue of your company? No. It was totally opposite with your question. As the citizens in HK becomes older and older, their requirement of the elderly instruments and healthcare in growth rapidly. In fact the target market in our industry is growing, the revenue of our company is in an enhancement. 5. How many resources had been spent on your strategy development projects? A lot! Human resources and Material resources which includes the instruments, medicines, equipments. I think it will over 100 millions. 6. What is / are your existing problem(s) that your company is facing now? And how does your company fix it? We have to find the Corp target carefully as many of them are not the legal one, whatever the mansion or doctor. We want to enlarge our clinic healthcare by a good quality. We would like asking the existing customers opinions and their past experience. Sometimes we need to find the good doctors by the positive word-of mouth. Thanks for your time and attention.

J.B.Priestley’s play, An Inspector Calls :: English Literature

AN INPSECTOR CALLS The six long years of anguish and fear had ended and the people of Britain were just recovering from the effects of World War Two. J.B Priestly a writer, who at the time was fifty one, was deeply involved with the war being a member of the infantry, and only just escaped death on a number of occasions. After his experiences throughout the horrific war, Priestly picked back up on his career which started before all of the battling and turned his attentions to writing plays. His first play after the war was known to be ‘An Inspector Calls’, which was eventually published in the same year. The story involves that of different opinions and actions, and of regrets. The rich and celebrated Birling family are spending a happy evening together celebrating the engagement of Sheila Birling to Gerald Croft – a marriage that will result in the merging of two successful local businesses. Yet, just when everything seems to be going so well, they receive a surprise visit from an Inspector Goole who is investigating the suicide of a young girl. He questions each one of the family members and future family members in turn about the suicide of Eva Smith, and as the play unravels it becomes evident that each member of the family has been intertwined with her life. J.B Priestly uses his play ‘An Inspector Calls’ as a way of getting across his socio-political views. He believed that people of different classes were being treated completely oppositely and demanded that something should be done. One of the key ways he emphasises points thorough the whole play is by the dramatic techniques he uses. In the course of An Inspector Calls the Birling family and Gerald Croft change from a state of great self-satisfaction to a state of extreme self-doubt. The play is in 'real time' - in other words, the story lasts exactly as long as the play is on the stage. So, what happens in a comparatively short time to create such a dramatic contrast? How is the drama maintained and the audience involved? Probably the main and most obvious dramatic technique that J.B Priestly uses is through the characters. The characters act as J.B Priestley’s thoughts and actions, and his emotions are unveiled throughout the play via them. As one of the most important and main characters in the play, Mr Birling is used in many ways as a dramatic device. The fact he cares only about himself and his family and not about anyone else in the world. We know this to be true, as just before the inspector arrives

Contemporary Symmetric Ciphers

Jordan University of Science and Technology Computer Engineering Department Cryptography & Network Security CPE (541) HW#5 Contemporary Symmetric Ciphers (Double-DES, Triple-DES & Blowfish) Supervised by: Dr Loai Tawalbeh Eng. Sulaiman Al-Basheer Simsam R. Hijjawi 20022171043 Review Problems: 6. 1 What is the triple encryption? It is a three-stages encryption with three different keys, to avoid costly requirements arises from using three different keys with total length of 3Ãâ€"56 = 186 bits a triple encryption with two keys maybe used. 6. 2 What is the meet in the middle attack?It's that attack doesn't depend on any particular property of the DES, instead, it will work against any type of block ciphers. For the double-DES cipher & a given (P,C) pair, this attack works as follow: 1. Encrypt the plaintext P with all possibilities of K1, store the results in a table, & sort that table by the value of X. 2. Decrypt C with all possible values of K2, check each resulted value with the en tries in the table, in case of match, check these two keys against another known pair (P1,C1), if match, accept them as the correct keys. 6. Why is the middle portion of 3DES is a decryption rather than an encryption ? 1. It's a decryption process in order to change the traditional nature of the DES, if it's an encryption, it'll stay a DES but with longer key size. 2. In the cryptography, there is no significance of using the decryption in the middle stage, the only advantage of doing so is to allow users of 3DES to decrypt data encrypted by the users of the older single DES ( C = Ek1[Dk2[Ek1[P]]] = Ek1[P]. Suppose that the middle portion is decryption instead of encryption, ( C = Ek1[Ek2[Ek1[P]]]The previous assumption in equation 1 will not be ever met. On the other hand 3. If an encryption process is done instead of decryption the meet-in-the-middle attack becomes possible. 6. 6 What primitive operations are used in Blowfish? †¢ Addition: Addition the words, it is performed modulo 2^32. †¢ Bitwise exclusive-OR. Problems: 6. 1 For the two design approaches introduced in the textbook, which is the preferred in the followings: Note: the suggested block cipher in my considerations below is DES. security. The single loop compact approach â€Å"single CBC loop† is more secure, this is because the EDE block contains the encryption function C = E k1[D k2[Ek1[P]]] without simplifications, this makes the cryptanalysis like differential attack more difficult than doing it on a simple loop with encryption or decryption process because each loop in the second approach appears like a simple DES that may be attacked alone in a chosen plain-text attack i. e. differential attack. – performance.The second 3 simple approach is the preferred from the performance wise point of view, this is because each block in each loop contains either encryption or decryption processes so it is faster than the first approach. But as I mentioned above, it is more vulne rable to cryptanalysis than the first approach because each loop is a single DES with differential attack possibility. We can also distinguish between the two approaches based on error propagation. 6. 2 Can you suggest security improvements to either option, using three DES chips & some number of XOR functions? Assume you are still limited to two keys.Changing the mode sounds a good solution: 1. For the first approach that contain only a single independent loop, using Counter mode seems to be simpler, because we deal with counters that less longer than plain texts & have no linear or statistical relationship, this may increase the performance of the 3DES in this case. 2. For the second approach, the dependency between stages prevents using the counter mode as an enhancement, a more secure mode is required in this case, using the CFB may eliminate the possibility of differential cryptanalysis because chosen plain text attack is not worth. . 4 Demonstrate that the blowfish decryption is the inverse of the blowfish encryption.

The Human Genome Project

The Human Genome Project (HGP) is a project undertaken with a goal to understand the genetic make-up of the human species by determining the DNA sequence of the human genome and the genome of a few model organisms. The project began in 1990 and, by some definitions, it was completed in 2003. It was one of the biggest investigational projects in the history of science. The mapping of the human genes was an important step in the development of medicines and other aspects of health care.Most of the genome DNA sequencing for the Human Genome Project was done by researchers at universities and research centers in the the United States and Great Britain, with other genome DNA sequencing done independently by the private company Celera Genomics. The HGP was originally aimed at the more than three billion nucleotides contained in a haploid reference human genome. Recently several groups have announced efforts to extend this to diploid human genomes including the International HapMap Project, Applied Biosystems, Perlegen, Illumina, JCVI, Personal Genome Project, and Roche-454.The â€Å"genome† of any given individual (except for identical twins and cloned animals) is unique; mapping â€Å"the human genome† involves sequencing multiple variations of each gene. The project did not study all of the DNA found in human cells; some heterochromatic areas (about 8% of the total) remain un-sequenced. International HGP Initiation of the Project was the culmination of several years of work supported by the Department of Energy, in particular workshops in 1984 [1] and 1986 and a subsequent initiative the Department of Energy. 2] This 1986 report stated boldly, â€Å"The ultimate goal of this initiative is to understand the human genome† and â€Å"Knowledge of the human genome is as necessary to the continuing progress of medicine and other health sciences as knowledge of human anatomy has been for the present state of medicine. † Candidate technologies w ere already being considered for the proposed undertaking at least as early as 1985. [3] James D. Watson was Head of the National Center for Human Genome Research at the National Institutes of Health (NIH) in the United States starting from 1988.Largely due to his disagreement with his boss, Bernadine Healy, over the issue of patenting genes, he was forced to resign in 1992. He was replaced by Francis Collins in April 1993, and the name of the Center was changed to the National Human Genome Research Institute (NHGRI) in 1997. The $3-billion project was formally founded in 1990 by the United States Department of Energy and the U. S. National Institutes of Health, and was expected to take 15 years. In addition to the United States, the international consortium comprised geneticists in China, France, Germany, Japan, and the United Kingdom.Due to widespread international cooperation and advances in the field of genomics (especially in sequence analysis), as well as major advances in com puting technology, a ‘rough draft' of the genome was finished in 2000 (announced jointly by then US president Bill Clinton and British Prime Minister Tony Blair on June 26, 2000). [4] Ongoing sequencing led to the announcement of the essentially complete genome in April 2003, 2 years earlier than planned. [5] In May 2006, another milestone was passed on the way to completion of the project, when the sequence of the last chromosome was published in the journal Nature. 6] There are multiple definitions of the â€Å"complete sequence of the human genome†. According to some of these definitions, the genome has already been completely sequenced, and according to other definitions, the genome has yet to be completely sequenced. There have been multiple popular press articles reporting that the genome was â€Å"complete. † The genome has been completely sequenced using the definition employed by the International Human Genome Project. A graphical history of the human ge nome project shows that most of the human genome was complete by the end of 2003.However, there are a number of regions of the human genome that can be considered unfinished. First, the central regions of each chromosome, known as centromeres, are highly repetitive DNA sequences that are difficult to sequence using current technology. The centromeres are millions (possibly tens of millions) of base pairs long, and for the most part these are entirely un-sequenced. Second, the ends of the chromosomes, called telomeres, are also highly repetitive, and for most of the 46 chromosome ends these too are incomplete.We do not know precisely how much sequence remains before we reach the telomeres of each chromosome, but as with the centromeres, current technology does not make it easy to get there. Third, there are several loci in each individual's genome that contain members of multigene families that are difficult to disentangle with shotgun sequencing methodologies – these multigen e families often encode proteins important for immune functions. It is likely that the centromeres and telomeres will remain un-sequenced until new technology is developed that facilitates their sequencing.Other than these regions, there remain a few dozen gaps scattered around the genome, some of them rather large, but there is hope that all these will be closed in the next couple of years. In summary: our best estimates of total genome size indicate that about 92% of the genome has been completed . Most of the remaining DNA is highly repetitive and unlikely to contain genes, but we cannot truly know until we sequence all of it. Understanding the functions of all the genes and their regulation is far from complete.The roles of junk DNA, the evolution of the genome, the differences between individuals, and many other questions are still the subject of intense study by laboratories all over the world. Goals The goals of the original HGP were not only to determine more than 3 billion base pairs in the human genome with a minimal error rate, but also to identify all the genes in this vast amount of data. This part of the project is still ongoing, although a preliminary count indicates about 30,000 genes in the human genome, which is fewer than predicted by many scientists.Another goal of the HGP was to develop faster, more efficient methods for DNA sequencing and sequence analysis and the transfer of these technologies to industry. The sequence of the human DNA is stored in databases available to anyone on the Internet. The U. S. National Center for Biotechnology Information (and sister organizations in Europe and Japan) house the gene sequence in a database known as Genbank, along with sequences of known and hypothetical genes and proteins.Other organizations such as the University of California, Santa Cruz[1], and Ensembl[2] present additional data and annotation and powerful tools for visualizing and searching it. Computer programs have been developed to analy ze the data, because the data themselves are difficult to interpret without such programs. The process of identifying the boundaries between genes and other features in raw DNA sequence is called genome annotation and is the domain of bioinformatics.While expert biologists make the best annotators, their work proceeds slowly, and computer programs are increasingly used to meet the high-throughput demands of genome sequencing projects. The best current technologies for annotation make use of statistical models that take advantage of parallels between DNA sequences and human language, using concepts from computer science such as formal grammars. Another, often overlooked, goal of the HGP is the study of its ethical, legal, and social implications.It is important to research these issues and find the most appropriate solutions before they become large dilemmas whose effect will manifest in the form of major political concerns. All humans have unique gene sequences; therefore the data p ublished by the HGP does not represent the exact sequence of each and every individual's genome. It is the combined genome of a small number of anonymous donors. The HGP genome is a scaffold for future work in identifying differences among individuals. Most of the current effort in identifying differences among individuals involves single nucleotide polymorphisms and the HapMap.How it was accomplished Funding came from the US government through the National Institutes of Health in the United States, and the UK charity, the Wellcome Trust, who funded the Sanger Institute (then the Sanger Centre) in Great Britain, as well as numerous other groups from around the world. The genome was broken into smaller pieces; approximately 150,000 base pairs in length. These pieces are called â€Å"bacterial artificial chromosomes†, or BACs, because they can be inserted into bacteria where they are copied by the bacterial DNA replication machinery.Each of these pieces was then sequenced separ ately as a small â€Å"shotgun† project and then assembled. The larger, 150,000 base pairs go together to create chromosomes. This is known as the â€Å"hierarchical shotgun† approach, because the genome is first broken into relatively large chunks, which are then mapped to chromosomes before being selected for sequencing. Celera Genomics HGP In 1998, a similar, privately funded quest was launched by the American researcher Craig Venter and his firm Celera Genomics.The $300 million Celera effort was intended to proceed at a faster pace and at a fraction of the cost of the roughly $3 billion publicly funded project. Celera used a riskier technique called whole genome shotgun sequencing, which had been used to sequence bacterial genomes of up to six million base pairs in length, but not for anything nearly as large as the three thousand million base pair human genome. Celera initially announced that it would seek patent protection on â€Å"only 200-300† genes, but later amended this to seeking â€Å"intellectual property protection† on â€Å"fully-characterized important structures† amounting to 100-300 targets.The firm eventually filed preliminary (â€Å"place-holder†) patent applications on 6,500 whole or partial genes. Celera also promised to publish their findings in accordance with the terms of the 1996 â€Å"Bermuda Statement,† by releasing new data quarterly (the HGP released its new data daily), although, unlike the publicly funded project, they would not permit free redistribution or commercial use of the data. In March 2000, President Clinton announced that the genome sequence could not be patented, and should be made freely available to all researchers.The statement sent Celera's stock plummeting and dragged down the biotechnology-heavy Nasdaq. The biotechnology sector lost about $50 billion in market capitalization in two days. Although the working draft was announced in June 2000, it was not until Feb ruary 2001 that Celera and the HGP scientists published details of their drafts. Special issues of Nature (which published the publicly funded project's scientific paper)[7] and Science (which published Celera's paper[8]) described the methods used to produce the draft sequence and offered analysis of the sequence.These drafts covered about 83% of the genome (90% of the euchromatic regions with 150,000 gaps and the order and orientation of many segments not yet established). In February 2001, at the time of the joint publications, press releases announced that the project had been completed by both groups. Improved drafts were announced in 2003 and 2005, filling in to ~92% of the sequence currently. The competition proved to be very good for the project, spurring the public groups to modify their strategy in order to accelerate progress. The rivals initially agreed to pool their data, but the agreement ell apart when Celera refused to deposit its data in the unrestricted public data base GenBank. Celera had incorporated the public data into their genome, but forbade the public effort to use Celera data. HGP is the most well known of many international genome projects aimed at sequencing the DNA of a specific organism. While the human DNA sequence offers the most tangible benefits, important developments in biology and medicine are predicted as a result of the sequencing of model organisms, including mice, fruit flies, zebrafish, yeast, nematodes, plants, and many microbial organisms and parasites.In 2004, researchers from the International Human Genome Sequencing Consortium (IHGSC) of the HGP announced a new estimate of 20,000 to 25,000 genes in the human genome. [9] Previously 30,000 to 40,000 had been predicted, while estimates at the start of the project reached up to as high as 2,000,000. The number continues to fluctuate and it is now expected that it will take many years to agree on a precise value for the number of genes in the human genome. History In 1 976, the genome of the virus Bacteriophage MS2 was the first complete genome to be determined, by Walter Fiers and his team at the University of Ghent (Ghent, Belgium). 10] The idea for the shotgun technique came from the use of an algorithm that combined sequence information from many small fragments of DNA to reconstruct a genome. This technique was pioneered by Frederick Sanger to sequence the genome of the Phage ? -X174, a tiny virus called a bacteriophage that was the first fully sequenced genome (DNA-sequence) in 1977. [11] The technique was called shotgun sequencing because the genome was broken into millions of pieces as if it had been blasted with a shotgun.In order to scale up the method, both the sequencing and genome assembly had to be automated, as they were in the 1980s. Those techniques were shown applicable to sequencing of the first free-living bacterial genome (1. 8 million base pairs) of Haemophilus influenzae in 1995 [12] and the first animal genome (~100 Mbp) [1 3] It involved the use of automated sequencers, longer individual sequences using approximately 500 base pairs at that time. Paired sequences separated by a fixed distance of around 2000 base pairs which were critical elements enabling the development f the first genome assembly programs for reconstruction of large regions of genomes (aka ‘contigs'). Three years later, in 1998, the announcement by the newly-formed Celera Genomics that it would scale up the shotgun sequencing method to the human genome was greeted with skepticism in some circles. The shotgun technique breaks the DNA into fragments of various sizes, ranging from 2,000 to 300,000 base pairs in length, forming what is called a DNA â€Å"library†. Using an automated DNA sequencer the DNA is read in 800bp lengths from both ends of each fragment.Using a complex genome assembly algorithm and a supercomputer, the pieces are combined and the genome can be reconstructed from the millions of short, 800 base pair fr agments. The success of both the public and privately funded effort hinged upon a new, more highly automated capillary DNA sequencing machine, called the Applied Biosystems 3700, that ran the DNA sequences through an extremely fine capillary tube rather than a flat gel. Even more critical was the development of a new, larger-scale genome assembly program, which could handle the 30-50 million sequences that would be required to sequence the entire human genome with this method.At the time, such a program did not exist. One of the first major projects at Celera Genomics was the development of this assembler, which was written in parallel with the construction of a large, highly automated genome sequencing factory. The first version of this assembler was demonstrated in 2000, when the Celera team joined forces with Professor Gerald Rubin to sequence the fruit fly Drosophila melanogaster using the whole-genome shotgun method[14]. At 130 million base pairs, it was at least 10 times large r than any genome previously shotgun assembled.One year later, the Celera team published their assembly of the three billion base pair human genome. How it was accomplished The IHGSC used pair-end sequencing plus whole-genome shotgun mapping of large (~100 Kbp) plasmid clones and shotgun sequencing of smaller plasmid sub-clones plus a variety of other mapping data to orient and check the assembly of each human chromosome[7]. The Celera group tried â€Å"whole-genome shotgun† sequencing without using the additional mapping scaffolding[8], but by including shredded public data raised questions [15].Whose genome was sequenced? In the IHGSC international public-sector Human Genome Project (HGP), researchers collected blood (female) or sperm (male) samples from a large number of donors. Only a few of many collected samples were processed as DNA resources. Thus the donor identities were protected so neither donors nor scientists could know whose DNA was sequenced. DNA clones from m any different libraries were used in the overall project, with most of those libraries being created by Dr.Pieter J. de Jong. It has been informally reported, and is well known in the genomics community, that much of the DNA for the public HGP came from a single anonymous male donor from Buffalo, New York (code name RP11). [16] HGP scientists used white blood cells from the blood of 2 male and 2 female donors (randomly selected from 20 of each) — each donor yielding a separate DNA library. One of these libraries (RP11) was used considerably more than others, due to quality considerations.One minor technical issue is that male samples contain only half as much DNA from the X and Y chromosomes as from the other 22 chromosomes (the autosomes); this happens because each male cell contains only one X and one Y chromosome, not two like other chromosomes (autosomes). (This is true for nearly all male cells not just sperm cells). Although the main sequencing phase of the HGP has been completed, studies of DNA variation continue in the International HapMap Project, whose goal is to identify patterns of single nucleotide polymorphism (SNP) groups (called haplotypes, or â€Å"haps†).The DNA samples for the HapMap came from a total of 270 individuals: Yoruba people in Ibadan, Nigeria; Japanese people in Tokyo; Han Chinese in Beijing; and the French Centre d’Etude du Polymorphisms Humain (CEPH) resource, which consisted of residents of the United States having ancestry from Western and Northern Europe. In the Celera Genomics private-sector project, DNA from five different individuals were used for sequencing. The lead scientist of Celera Genomics at that time, Craig Venter, later acknowledged (in a public letter to the journal Science) that his DNA was one of those in the pool[17].On September 4th, 2007, a team led by Craig Venter, published his complete DNA sequence[18], unveiling the six-billion-letter genome of a single individual for the first time . Benefits The work on interpretation of genome data is still in its initial stages. It is anticipated that detailed knowledge of the human genome will provide new avenues for advances in medicine and biotechnology. Clear practical results of the project emerged even before the work was finished.For example, a number of companies, such as Myriad Genetics started offering easy ways to administer genetic tests that can show predisposition to a variety of illnesses, including breast cancer, disorders of hemostasis, cystic fibrosis, liver diseases and many others. Also, the etiologies for cancers, Alzheimer's disease and other areas of clinical interest are considered likely to benefit from genome information and possibly may lead in the long term to significant advances in their management. There are also many tangible benefits for biological scientists.For example, a researcher investigating a certain form of cancer may have narrowed down his/her search to a particular gene. By visiti ng the human genome database on the worldwide web, this researcher can examine what other scientists have written about this gene, including (potentially) the three-dimensional structure of its product, its function(s), its evolutionary relationships to other human genes, or to genes in mice or yeast or fruit flies, possible detrimental mutations, interactions with other genes, body tissues in which this gene is activated, diseases associated with this gene or other datatypes.Further, deeper understanding of the disease processes at the level of molecular biology may determine new therapeutic procedures. Given the established importance of DNA in molecular biology and its central role in determining the fundamental operation of cellular processes, it is likely that expanded knowledge in this area will facilitate medical advances in numerous areas of clinical interest that may not have been possible without them. The analysis of similarities between DNA sequences from different organ isms is also opening new avenues in the study of the theory of evolution.In many cases, evolutionary questions can now be framed in terms of molecular biology; indeed, many major evolutionary milestones (the emergence of the ribosome and organelles, the development of embryos with body plans, the vertebrate immune system) can be related to the molecular level. Many questions about the similarities and differences between humans and our closest relatives (the primates, and indeed the other mammals) are expected to be illuminated by the data from this project.The Human Genome Diversity Project, spinoff research aimed at mapping the DNA that varies between human ethnic groups, which was rumored to have been halted, actually did continue and to date has yielded new conclusions. In the future, HGDP could possibly expose new data in disease surveillance, human development and anthropology. HGDP could unlock secrets behind and create new strategies for managing the vulnerability of ethnic groups to certain diseases (see race in biomedicine). It could also show how human populations have adapted to these vulnerabilities. The Human Genome Project When populations start to die there are only so many to choose from for genes. A founder effect will then be created (Welsch 73). The Human Genome Project set out to identify all the genetic material in humans (Welsch 265). Another type of variation is different from genes it is physiological. Our blood type is a protein on our red blood cells and delivers oxygen and immune responses ( Welsch 267). We are only able to give blood to those who have our same blood type unless we have the blood type that is the universal donor. We have a friend who has suffered miscarriages, the most recent was 26 weeks along. Her body keeps rejecting the baby and they are not sure what the cause is. They are sure that it is not the RH factor. The white blood cells also have their own set of proteins, the human leukocyte antigen system (HLA). This system protects our bodies from foreign objects or infectious agents (Welsch 268). Even within our families we are varied because we will not all have the same combination of the system. We all react to infections and diseases differently. My husband is highly allergic to artificial smells. His system seems to be in overdrive. When he was in the military his bunk mate sprayed scented aerosol deodorant and his throat closed up. He then realized he could not handle anything artificial. My friend's cousin had a double lung transplant last year. Several months after her transplant she got an infection and her body rejected her new lungs and she passed away. I think her rejection to the new lungs was because of the differences in the HLA system of her body and the donor's. Our bodies also adapt and look different from others in our skin tone and our body types. These traits are not as significant in our bodily functions but are varied nonetheless. W all can have different hair color, skin color, and shape and sizes. Our skin does not really have color, it has a pigment called melanin ( Welsch 271). Depending on where the person lived they may have more melanin production and have darker skin. Some can also be tall and skin or short and chubby. We measure this through the anthropometry. It helps determine the variations we see. We put these measurements in the cormic index, which is sitting height to standing height ( Welsch 273). The intemembral index is the ratio of arm length to leg length (Welsch 273). Body fat is determined by the BMI or body mass index. A person can be too skinny or too fat and have a BMI that is not healthy. Another variation is race. This our society's system for classifying people based on how they look. These differences are believed to reflect the root of genetic and biological differences. We also adapt to the environments we encounter. We can either allow our environment to change us or we can change the environment. To survive we have to figure out what needs to change and react accordingly. We have to have a certain plasticity. We all change during our lifetime and it comes somewhat from our surroundings. We can perform niche construction and make our environment suitable to our living conditions. On the farm my in laws own they do several things to insure their success. They have to give the cows shots to make sure they are healthy enough for reproduction and the babies will be healthy enough to be sold. They take care of the grass and the other parts of the land to ensure the cows are fed during the spring, summer and fall. They make sure that there is enough hay to feed them during the winter. As parents we have the ability to help our children adapt. To set them up for success in life as humans. We teach our children how to cook, clean, read, and write. The ability to care for themselves spans across generations. They will teach their own children these abilities to adapt and survive in the world around them. We pass this on to them through extra-genetic inheritance. We have a new emergence of new species through speciation. Differences can be so vast that it becomes a totally different species. Such as the dog and the wolf. Both have canine but the wolf is considered a different species. Evolution takes place as we experience different things in our culture. We have to adapt as our culture changes. The constructivist approach shows that our biology is a process of construction (Welsch 239). Our bodies work in combination with our genes to affect how genes can be expressed or epigenetic system of inheritance ( Welsch 240). When our genes are altered we can pass those down to our children affecting how their bodies work and how they behave. The way we raise our children affects how they will behave as adults. If we are nurturing, loving and kind to our children almost all of the time these will be the traits they possess unless they have something else going on biologically. If we behave negative with our children and this is all they see they will in turn possess those traits. This is the behavioral system of inheritance. We also store symbols and communicate them with others around us, showing the world our understanding through them. The symbols we use come from the symbolic system of inheritance. Through manipulating the world around us and changing the world around us it is important to our biocultural evolution. Change is an important part of who we are. Just as when we move into a new home, a new town, new school, and even a new job we change and construct the environment to fit our needs. We do certain things so we can fit in and feel comfortable. It allows us to thrive. We even try to change the land we live on. Another aspect of biocultural evolution is the evolution of our behaviors. Sociobiology explains our behaviors as related to our biological component (Welsch 245). Our behavior can also be influenced by the earth and social things going on around us. This comes from the human behavioral ecology (HBE) (Welsch 246). We adapt our behavior to our society so that we can fit and continue to evolve. Our behaviors are directly connected to our biological self. This comes from biological determinism (Welsch 247). Some of them come forward or (emergence) based on who we see and interact with in our daily lives. We adapt and change through our diet, moving to different places, and sometimes we even change our bodies through modification to make ourselves fit in. Just like runway models who extreme diet and workout to be tiny enough to be considered for the runway. This shapes our cultures around the world and how we all view each other. Everyone in this world is so unique. No two people even family members will be completely identical. Our bodies adapt and varied through the generations to be continued successfully. We all try to fit in with our behaviors so that our true biological self can come forward. We need to be conscious in the things we teach our children because they will be the next generation and bring forth a new culture. Works CitedWelsch, Robert Louis, et al.
