Protective effects of human cerebrospinal fluid antioxidants against enzyme inactivation caused by metal-catalyzed oxidation systems were investigated. When purified glutamine synthetase(GS) was incubated with human cerebrospinal fluid(CSF), the enzyme was progressively inactivated. Catalase and EDTA could inhibit the enzyme inactivation by 50-80%. Small-molecular(Mr< -10,000) fraction of CSF inactivated the exogenous GS, but large-molecular(Mr> -10,000) fraction did not. The GS inactivation by the small-molecular fraction was also markedly inhibited by catalase and EDTA. These results suggested that metal-catalyzed oxidation is involved in the GS inactivation by the small-molecular fraction of CSF. Dithiothreitol(DTT) was shown to inhibit almost completely the oxidative inactivation of GS by CSF. However, DTT inhibited only partially the oxidative inactivation of GS caused by small-molecular fraction of CSF. When large-molecular fraction of CSF was separated by anion-exchange HPLC chromatogrpahy, there was a peak of antioxidant activity inhibiting the small-molecular fraction-induced GS inactivation in the presence of DTT. The antioxidant activity was neutralized by monoclonal antibodies to transthyretin. Purified transthyretin was found to efficiently inhibit ascorbate/Cu^(2+)-induced GS inactivation in the presence of DTT. Uric acid and glucose did not show any protective effect on the GS inactivation in the same condition. The above results suggest that metal-catalyzed oxidation occurs normally in human CSF, and that transthyretin may play an important role as a CSF antioxidant in protecting proteins from metal-catalyzed oxidation.

비엔나협약에서 계약위반에 대한 당사자의 구제권에 관한 연구

This study focused on the choice and exercise of parties' remedy rights for breach of contracts provided in the Vienna convention(United Nations Convention on Contracts for the International Sale of Goods : CISG). In order to these analysis, We examined the provisions on the parties' remedies for breach of contracts under the Vienna Convention Through this, We found that there were important problems in choice and exercise of parties' remedy rights provided in the Vienna Convention as follow : ① Several restrictions in exercise of the right to require performance. ② Difficulties in judgement of the fundamental breach. ③ Problems in choice between the right to price reduce and the right to claim damages. ④ Problems in action of the other rights. These problems are mainly due to limits which is latent in the provisions. But parties could be cover several expected problems in choice and exercise of parties' remedy rights by contracting special agreements between parties or by understanding the related provisions in the Vienna Convention. Therefore We presented some practical alternatives to the above problems.

A 36-year old woman with end stage renal failure and hypertension was transferred from a university hospital to our emergency department due to a enlarging right cervical mass associated with a palpable thrill and a bruit. Over a 2 month period, she required hemodialysis for severe azotemia at a university hospital in Seoul. 3 days after a difficult attempt at a internal jugular cannulation, she developed a progressive swelling in the right lower cervical area. An arch and primary branch arteriogram revealed a arteriovenous fistula between right innominate artery and internal jugular vein with a large intervening pseudoaneurysm. She underwent vascular surgery within 1 week of injury and subsequent postoperative angiogram showed complete resolution of the fistula. This rare condition is reported with a review of the literature.

Mobile Ad-hoc Network is used much by network creation method of USN or BcN, and especially this is used often situation that do not compose network infra with natural disaster. In the Mobile Ad-hoc network, network structure nodes are continuously capable of movement, and because for certain periods of time do not receive power, there are battery limitations. In this paper we deal with concurrently reaction of topology changing and life time of network to propose hybrid protocol named AOMDV-La and OLSR-ME Afterwards, we compared the results after testing the ZRP protocols with the proposed protocols to prove the superior quality of the proposed protocols.

Frozen dough of two flour, Tazo and Tazo-S, and two thawing, room and cold temperature, were determined to qualified bread quality. For best bread quality from frozen doughs, very strong flour should be used. Frozen doughs are increasingly being produced in the baking industry even though they generally provide bread with lower loaf volume than dose unfrozen fresh dough. Several investigators have reported that the major changes in doughs that have been frozen are related to yeast. During the dough fermentation, yeast produces carbon dioxide and flavor compounds. Loaf volume decreased markedly with freezing and thawing, and gradually during frozen storage.

The quantity of goods transported of port process ability which is the possibility of computing power from the point of view where the competitive power of the nation becomes maximization proceess ability more important than anything. From many research, it conducts the various effort that automatic or intelligence of port, for the maximization port processing ability. Port has important national institution and always used to us for everyday. It is difficult to invest experimental due to improved cost expensive. For maximization ability of port, it is very frequently used through simulation and then predicts a result. This paper describes the "design method and port modeling for port integral management simulator development" that partitions into five phases for maximization ability of port. This paper describes to design simulator for design scheme and give elaboration for it through 3D modeiling of transported goods. Through make this simulator, will help to reseach for quantity of goods transported of port. 항만 통합 관리 시뮬레이터 개발 방안을 주제 로 한 본 논문에서는 크게 두 가지의 기법을 제안하였다. 첫째 항만 의 하역 과정에는 매우 많은 입력인자 와 단계가 존재하므로 각 과정별로 분리하고 문제 해결 방안을 단순화 시킬 수 있는 시뮬레이터 설계 방안을 제안하였다. 둘째 하역 과정별로 모듈 을 구성하고 각 모듈들이 시뮬레이터 되는 동안의 현실감 및 관찰을 수행하기 위한 3D 그래픽을 적용할 수 있는 방안을 기법을 제안 하였다. 첫째 제안은 하역 과정을 5단계로 분리하여 각각의 독립적인 모듈로 구성하고 이를 향후에 통합하는 방식을 취함 으로써 달성하였다 둘째 제안의 경우 는 현재 게임 동의 개발에 다양하게 적용되는 Direct 3D API를 적용하고 3D 장비생성에는 이미지 생성 툴을 활용함으로써 달성하였다. 이를 통하여 항만 하역 과정에 대한 효율적인 시뮬레이션을 수행할 수 있고 최적 처리 과정을 빠르게 도출할 수 있다. 더불어 시뮬레이션 과정을 가상 항만의 움직임과 함께 확인할 수 있어 실제 항만에서의 하역 과정을 유사하게 묘사할 수 있다. 향후 과제로는 항만에 실제 존재하는 풍속 파도의 움직임을 고려하고 더불어 배후 부지 및 도로 등과 연계할 수 있는 시뮬레이터를 개발, 구현하는 것이다.

본 논문에서는 해안 지하수 개발 시뮬레이터인 SIOP의 전후 처리 부 설계와 구현을 수행 하였다. 시뮬레이터 의 사용에 있어 입출력의 난해함이 시뮬레이터 생산성을 감소시키기 때문에 이를 해결하기 위한 GUI 기반의 전후 처리 부를 수치처리 시뮬레이터인 SIOP에 연동 시켰다. SIOP은 3개의 입력 파일을 필요로 하며,각 파일마다 복잡한 수치정보를 입력해야 하는데 보다 직관적인 인터페이스를 통하여 입력할 수 있도록 하였고, 자동 입력이 가능한 부분을 증가 시켜 입력 파일의 생성 시간을 감소시켰다. 또한 수치지도를 로드 할 수 있는 기능을 포함하여 수치지도 상에서 대화형으로 입력 작업을 수행 할 수 있도록 하였다. 전후 처리 부는 SIOP의 시뮬레이션 결과 파일을 텍스트 형태의 출력에서 시각적인 출력으로 재 처리 하는 프로그램이다. 그래픽 컴포넌트를 활용 하여 4개의 Plot과 최적산출량의 표시가 가능 하도록 구현하였다. 프로그램 구조는 재사용과 수정이 용이하도록 독립적인 객체를 적용하였다. 본 논문에서 구현한 GUI의 전후 처리 부를 통하여 시뮬레이션 수행을 위한 사전 작업과 결과 해석 작업의 시간을 대폭 감소 시켜 향후 사용자들이 보다 편리하게 시뮬레이터를 사용하는 것이 가능하다. 따라서 SIOP 시뮬레이터는 해안지하수 확보를 위한 다양한 실험에 쉽게 활용될 수 있을 것이다. 향후 과제로는 전후 처리부의 기능 추가 및 최적화 작업이 있다. Research is progressing in several fields to secure insufficient water resoruces in the future. Approach method for deverlopment of water resource and studies area are defference, but research method is simulation in various research field Good points of Simulation can get various result of studies and be reduce genesis of dangers and expense.

Many researchers have studied the theme on CASE technology. However, there are no many researches which lightened the diffusion of CASE technology and organizational change. The purpose of this study is to investigate the factors that influence on the diffusion of CASE technology and the way how IS organization changes as a result of the diffusion. We exploited a case study research as a methodology. We selected five software development firms which possessed the leading IS technology abilities as the case companies. We realized that the diffusion of CASE technology proceeded under the three context variables - managerial context of information systems, the intent and behavior of key players and implementation strategy of organization - to enhance the performance of information systems. The contribution of this study is to clarify the change of IS organization as a result of CASE technology diffusion. This study has the limitation that tried to analyzed the organizational change only in a direction.
