Comparative genomic hybridization (CGH) is an important molecular cytogenetics technique that maps abnormal copy number of specific DNA sequence of the chromosome. CGH is based on quantitative digital image analysis of ratio images from fluorescently labeled chromosomes. In this paper, we would like to introduce how recently developed image analysis algorithms are used for CGH techniques. To average the ratio profile of each chromosome, binarization, skeletonization, and stretching of chromosome images have been studied. Developed algorithms have been implemented in the karyotyping system ChIPS commercially developed at Biomedlab Co. Ltd.

Recently, interest in traditional medicine has increased steadily. Nations having traditional medicine system have been attempting to change it institutionally for the purpose of public application boost in use of traditional medicine. But there are not too many countries which have established the modern system of education and licensing system for traditional medicine with it maintained as a part of a national health care system. The best known examples of nations utilizing traditional medicine are the People's Republic of China, Republic of Korea, Japan, and Taiwan. These countries follow different patterns in the relationship with western medicine according to different social and historical backgrounds. Taiwan has dual medical system as Korean. In this study, we looked through history and the current state of affairs of national health care system in Taiwan, and also found out the licensing system, the educational system, and the curriculum in several universities. thoroughly. Furthermore, we looked into the direction of the policy of Taiwanese health care system which has been becoming an integrated medical system between traditional Chinese medicine and western medicine. With findings based on this study, we deduced implications of a future policy line about the integrated medical system in Korea to minimize conflicts between the concerned parties.

Conventional parking survey has been usually performed by a person, which has a lot of problems such as decreased mobility, data input error, longer time and expensiveness. Therefore, this study attempted to develop an automatic parking survey method using lately commercialized equipments that were highly efficient imagery interpretation equipments, GPS, and infrared lighting fixtures. In addition, this study developed a parking analysis software that enables to modify and save data, and analyze survey data by the automatic parking survey method. When parking survey is conducted using automatic parking survey method, surveying accuracy is influenced by the running speed of a surveying vehicle, the photographing angle of an imagery interpretation equipment, the gap between parking vehicles and the distance of a surveying vehicle to parking vehicles. Therefore, this study drew optimum conditions by testing on each items for accuracy improvement, and developed a parking analysis software for systematic storage and management of parking survey data, supporting the parking analysis and output the parking analysis result.

The domestic casino industry is attempting to change from the existing single form to the advanced-type of complex casino resort. In addition, the importance of the security management system, which prevents and responds to accidents caused by negative influences of gambling, is emphasized at the casino enterprise level. Therefore, this study aimed to find measures to revitalize the security management system for domestic casinos only for foreigners through an analysis of relevant literature and case studies. As a result of the analysis, it was found that in order to effectively cope with changes in the casino industry, three areas were needed to be revamped: (1) a lack of protocols which intend to protect casino security personnel, (2) an inefficient operational system due to the dualized casino security management system, and (3) a lack of systematic educational system for casino security personnel. This study therefore proposed three measures: (1) a review of revisions of related laws to protect casino security personnel, (2) enhancement of professionalism of casino security personnel and (3) establishment of a single operating system of the casino security management operating system.

The purpose of this study is to propose the improvement strategies for policy information services of National Library of Korea, Sejong through analysis of their current status and problems. For the study, we conducted interviews with service providers and users and identified some issues in provision and use of the services. Specifically, we found problems of service provision system characterized by dualization and decentralization, and further identified specific issues with provision of individual services. Moreover, the interviews with service users suggested user types, user perception of the service, and problems in the use of individual services. Based on the findings, we proposed improvement strategies in six aspects: collection, services, organization, system, promotion, and cooperation. We hope these strategies contribute to vitalizing the policy information services of National Library of Korea, Sejong.

Objectives: The main purpose of this study is to find a solution for modernized classification of herbal medicinal preparations in dual medical systems. Through this study, we expect to provide a reasonable foundation of herbal medicine for public health. Methods: We studied legal or technical terms of herbal medicinal preparations from the past regulations, and through this procedure, we could suggest clear definitions of terms for herbal medicinal preparations. We also investigated documents for approval of herbal medicinal preparation from US, EU(European union), The People's Republic of China, Japan, so that we can refer to them to revise regulation for appropriate use of herbal preparations. Results: In Korea pharmaceutical affairs act, any basis of 'Crude drugs' does not exist. But in some subordinary notifications, the way that they use the 'Natural product medicine' is used as a means of limiting basic rights of doctor or pharmacist of Korean medicine compared to doctor or pharmacist. At the same time, in subordinary notifications, provisions are vague and not enough for scientific evidence of Korean medicine. Thus, we re-categorized herbal medicinal preparations into new drugs, drugs made from herbal medicinal preparations and suggested requirements for drug approval. Conclusions: Instead of using the term 'Crude drug preparations', and we should use term 'Herbal medicinal preparations' in related act and notification. And also we suggest to amend subordinary regulations and documents for approval of herbal medicinal preparations. Through this, we can make herbal medicinal preparations be more industrialized.

Turnkey and alternative-design contracts was introduced operation in the country from january 2004 to February 2010. this was introduced operation. The selecting method of contractor for turnkey projects has being operated by an open forum type that consists of technical committee and appraisal committee in an integrated design approach deliberations. But to improve the operation of the problems, the government is operating design review committee consisting of the central, local and special design advisory committee in march 2010. But this system has also been suggested as still problems, too many contracts by large companies, increasing of design cost and excessive competition. This study is intended to contribute that turnkey and alternative-design contracts can be well operated in domestic construction markets. In this paper suggests some improvement methods and operational problems caused from application of an open forum type for selecting contractor of turnkey project.

This paper proposes an integrated scheduling mechanism for embedded system with real-time web server to meet the characteristics of real time task. The proposed scheduling mechanism may solve the so-called priority inversion problem in scheduling between urgent web requests and tasks with low priorities. The priority inversion problem happens because of operating two independent schedulers, web scheduler and operating system scheduler in a system without considering the requirements of each other. In the proposed mechanism, two schedulers are integrated in an operating system and the integrated scheduler schedules tasks for urgent web requests with real time characteristics and other application tasks together. Since all tasks are scheduled by one unified scheduler that knows the characteristics of tasks, the tasks are scheduled with their absolute priorities and thus the priority inversion problem can be eliminated. The performance is measured on a prototype embedded system with the proposed algorithm.
