Today is a society of knowledge and information-a digital information society, characterized by the Internet media, It is different from the analog system in many ways. Copyright Law is getting more important in this society. Compared with other laws, Copyright Law has developed later, but now, as Property Law, is not less important than Law of Realty and Law of Obligation. The digital society is featured by a wide sea of information linked to the Internet. The development of the Internet has led to new political, social, cultural, and economic changes. Digital techniques have made copies easier and more convenient, which led to infringement of copyright. The protection of Copyright Law can refer to that of digital works, but not copyright holders. This means Copyright Law is to protect digital works themselves, but not the ideas of copyright holders. The highway information network has brought out the problems of the protection of Copyright Law. To solve the problems between copyright holders and internet users, it is considered important to determine what types of copyrights are violated. In accordance with the development of human society, specially science and technology, recently it covers not only traditional works, such as books, art, photographs and sculpture, but also computer programs, semiconductor chips, microfilms, etc. The infringement of copyright has increased, therefor it is much more important than before to protect copyright. To protect man's creative activities, creative activities and their products need to be recognized as object of right which needs protecting. There are three remedies for the infringement-managerial, civil, and criminal. This study is limited to a civil remedy.

Purpose: Liver cell damage after ischemia and reperfusion injury has been a major cause of death after liver surgery. Yet there have been no exact and practical guidelines for assessing liver cell damage after ischemia and reperfusion injury. The aim of this study was to estimate the liver cell viability after ischemia and reperfusion injury. Methods: A 70% partial liver occlusion model with employing Spraque Dawley Rats was used. The ATP content of the liver tissue, the palmitic acid metabolic rate and the histologic change (H/E, TUNEL stain) were all measured at 30 minute intervals to assess liver cell viability during 120 minutes of ischemia. At 24 hours reperfusion after 30, 60 and 120 minutes ischemia, the same parameters and the AST/ALT level in the blood were measured. Results: The ATP content was decreased below 20% compared to normal liver after ischemia, but there were no significant changes in the histology and the palmitic acid metabolic rate during 120 minutes ischemia. At 24 hours reperfusion after 30, 60 and 120 minutes ischemia, the ATP content was decreased to around 50% in all the groups and the palmitic acid metabolic rate was decreased 90.9±2.4%, 80.0±5.3% and 79.1±7.7%, respectively, compared to the control liver. But histologic change was not as great as the change in the ATP content and the palmitic acid metabolic rate. Conclusion: Judging by these results, liver has relatively good tolerance during ischemia, but after reperfusion, the liver showed damage depending on the duration of ischemia. This study might be very helpful as a guide line of liver damage after ischemia and reperfusion in both clinical practice and basic research.

이동 에이전트 기반의 웹 서버 부하 모니터링 시스템 구현

박홍진,Park, Hong-Jin 대한전자공학회 2002 電子工學會論文誌-CI (Computer and Information) Vol.39 No.6

인테넷이 급격히 발전함에 따라 인터넷 사용자가 크게 증가하고 있으며, 이에 따른 웹 서버의 중요성도 증가되고 있다. 인기있는 웹 사이트는 사용자의 집중현상으로 웹서버의 부하가 크게 증가하여 오류가 발생하거나 웹서비스가 중단되는 현상이 발생하기도 한다. 따라서 올바른 웹서비스를 제공하며 웹서버의 성능 관리를 위해서 웹서버의 부하를 효율적으로 모니터링하는 기술이 필수적이다. 기존 클라이언트-서버 방식을 이용한 웹 부하모니터링 기법은 서버 프로그램을 모든 웹 서버에 미리 설치해야하는 문제점이 있다. 본 논문은 클라이언트 서버 방식의 문제점을 해결하기 위해 이동 에이전트를 이용한 웹 서버 부하 모니터링 시스템을 구현한다. 이동 에이전트를 기반하여 구현된 시스템은 미리 프로그램을 설치할 필요가 없으며 네트워크 트래픽을 줄이고 웹서버의 추가적인 부하를 줄일수 있다. According to the rapid evolution of internet, the number of internet users has greatly increased, so that the web servers are getting more important. If there are a great number of users trying to connect to a popular web server, the load of the web server will increase rapidly, so that failures may occur or web services may stop. An efficient load monitoring technique is required for the available web services and the performance management. The traditional techniques for load monitoring of web server using the client-server method have the problem that the server programs in client-server method must be pre-installed to all web servers. This paper implements web server load monitoring system using the mobile agent in order to overcome the problem of client-server computing. The system based on the mobile agent has no need to install the program in advance and it reduces the network traffic and the additional overheads in web servers.

무선 기반의 실시간 부하 모니터링 시스템

박홍진,Park, Hong-Jin 한국컴퓨터산업학회 2004 컴퓨터産業敎育學會論文誌 Vol.5 No.9

The computer system is gradually complicated because of explosive growth of computer system and IT technology. For efficient management of complicated system, system load monitoring technology is essential. In this paper, we is implemented the real-time load monitoring system based mobile than the traditional methods that are used load-related commands in system manager or specific load application programs based connected wire. Advantage of implemented load monitoring system in this paper is freely saw load information in time and space though mobile method like as PDA, cellular phone, more than traditional methods intime and space. 컴퓨터 시스템과 IT 기술의 폭발적인 발전으로 인해 컴퓨터 시스템은 점점 복잡해지고 있다. 복잡한 시스템을 보다 효율적으로 관리하기 위해서는 시스템 부하 모니터링기술이 필요하다. 본 논문은 기존의 관리자가 부하 정보 관련 명령어를 이용하거나 유선기반의 특정 모니터링 프로그램을 수행하는 방식에서 무선 기반의 실시간 부하 모니터링 시스템을 구현한다. 본 논문에서 구현된 부하 모니터링 시스템 기존 방식보다 실시간적이면서 시공간에 자유롭게 부하 정보를 확인 할 수 있는 장점이 있다.

최근 구급차에 탑승하는 응급 구조사의 인원이 턱없이 부족하여 소방관 한 사람만이 구급차에 타고 환자를 이송하는 일이 종종 문제시 되곤 한다. 응급환자가 발생 시 신속하고 정확한 조치가 무엇보다도 필요하며 특히, 환자에게 적합한 의료기기가 있는 전문적인 병원으로 이송해야한다. 본 논문은 스마트 폰을 이용하여 병원 전 단계의 응급의료 시스템을 구현한다. 구현된 시스템은 환자 이송 중에 환자의 심박동을 실시간적으로 모니터링이나, 과거 환자의 병력 정보 등을 파악할 수 있으며, 환자가 필요로 하는 응급 병원 정보도 제공하여 병원 전 단계에서 응급 환자에게 신속하고 효율적인 처치가 가능한 환경을 제공한다. Recently, the task in which the number of people of the emergency medical technician whom it boards the ambulance is unreasonably insufficient and in which the fire fighter one person gets in the ambulance and which transfers the patient comes into question often. When the emergency patient is generated, it has to transfer to the special hospital in which above anything else, the measure which is quick and exact is needed and where there is the medical device which is suitable for particularly, the patient. This paper implementations the emergency medical system by the smart phone. The implemented system monitors the heart beat of the patient the monitoring among the patient transport with the real-time type. It can grasp the medical history information of the patient, and etc. in the past. And the system provides the emergency hospital which the patient requires and the pre-hospital phase provides the environment in which the disposition which is quick and efficient is possible to the emergency patient.

To support multimedia application such as a multimedia communication systems and multimedia broadcasting, an operating system need to predict their timing-constraints. So, In this real_time systems, we must solve the priority inversion problem that may make the behavior of unpredictable systems and need a real-time server model that provides a better preemptability and minimizes a system overhead. In current real-time systems, the single thread server model, the worker model and the dynamic server model are being used for synchronization but they cannot propose an effective structure for managing shared resources. In this paper, the priority inheritance protocol is used to solve the priority inversion problem and the hybrid prioritized worker model is proposed, which can provide a more effective structure and a faster response time minimizing a system overhead. The hybrid prioritized worker model is to combine the static and the dynamic prioritizes worker model, and have a better performance than other models in response time which is an important factor in a real-time system.

박홍진 ( Hong-jin Park ) 한국정보처리학회 2006 한국정보처리학회 학술대회논문집 Vol.13 No.1

웹 인프라와 P2P 기술 개념을 기반으로 연구되고 있는 데이터 그리드 컴퓨팅 환경에서 중요한 문제 중 하나는 거대한 데이터 자료 접근에 관한 이슈이다. 요청된 자원 공간을 확보하기위해 저장되어 있는 자원을 선택하는 “캐쉬 교체 정책” 연구는 많이 연구되어 왔으나, 상항을 미리 예측하거나 스택과 같은 추가적인 자원이 필요하다. 본 논문은 기존 연구의 문제점을 해결하고 요청된 파일에 대응되는 파일의 개수가 되도록 적게 하기위해 파일 크기를 고려한 캐쉬 교체 정책을 제안하고 있다.
