The work reported in this paper identifies the thermal-hydraulic phenomena that are expected to occur during a number of key transients in SMART(System-integrated Modular Advanced ReacTor) which is under development at KAERI. The result of this effort is based on the current design concept of SMART integral reactor. Although the design is still evolving, the preliminary phenomena Identification and Ranking Table(PIRT) has been developed based on the experts' knowledge and experience. The preliminary PIRT has been developed by consensus of KAERI expert panelists and AHP(Analytical Hierarchy Process). Preliminary PIRT developed in this paper is intended to be used to identify and integrate development areas of further experimental tests needed, thermal hydraulic models and correlations and code improvements for the safety analysis of the SMART.

이 논문은 인간의 주관적인 판단에 의한 의식구조문제를 취급한다. 의식구조를모델링하는 방법으로 퍼지구조 모델링법이 있으나, 이 방법은 인간의 주관적인 판단의 일대비교의 회수가 많고, 판단에 대한 전도라고 할 수 있는 정합성을 체크하기 어렵다. 이러한 점들을 개선하기 위한 방법으로서 AHP에서의 일대비교행렬의 개념을 이용한 행렬에 의한 퍼지구조모델링법으로서 의식을 구조화한다. 이 방법의 유효성은 품질시스템구축에 대한 의식 구조그래프에 의하여 보이고자 한다.

고병원성 조류 인플루엔자는 빠른 확산과 높은 치사율로 인하여 발병 초기에 질병의 확산경로 및 확산범위를 예측한다는 것은 매우 어려운 문제이면서 동시에 반듯이 해결해야만 하는 중요한 과제이다. 본 연구에서는 공개된 법정 고병원성 조류인플루엔자의 발병데이터를 기반으로 순차패턴 마이닝을 적용하여 질병의 순차적인 확산경로 규칙을 도출한 후, 그 결과를 바탕으로 지역개념계층(location concept hierarchy)에 따른 추상화 레벨의 점진적인 조절을 통하여 지역 원도우의 확대와 축소를 적용함으로써 도시(city)레벨부터 리(street)레벨까지의 질병확산경로 그래프와 GIS기반의 질병확산경로에 대한 분석을 시도하였다.

This study is about implementing an job matching web service system based on the Job seeker's company assessment model proposed by the researchers. Basically, the Job seekers' company assessment model is based on the concept that each job seeker can evaluate the recruitment company candidates using job seekers's own major consideration factors. Using the implemented information system, each job seeker's main considerations in job searching process are evaluated and stored and compared to those of other job seekers' or groups' characterized by sex, job experience residential area and etc. by finding out and listing up the companies in the order of the preference of job seeker own or belonging groups, job seekers can be helped to find suitable companies which fit well to themselves.

Background : Currently, ontology research has led the trend of technical development in medical informatics area. For Korean medicine, the reference terminology should be developed to facilitate the ontology research. Objective : This research aimed to design the management system for traditional Korean medical terms. Method :We built the internet-based system in which multi-users work simultaneously by using the relational database system(SQL Server2005) and visual studio 2005. Result : By this system, researchers can collect, refine, and inspect Korean medicine terms efficiently, and the terms can be transcribed into synonym, Korean, Chinese, and simplified Chinese. It enables the terms be input into the system accurately and managed by its classification. Conclusion : We developed the concept groups and its hierarchy system for Korean medicine terms which provides the basis for ontology system.

This study aims at evaluating the spatial configuration of general hospitals in terms of Visitors' movement pattern. In doing so, the study deals with three hospitals which are recently built and are generally considered to show recent trends in their spatial configuration. First, the Space Syntax method is used in order to systematically describe and analyse the spatial configurations, and thus to find out the spatial characteristics of each hospital in terms of movement pattern. Second, the spatial characteristics reflected on the 1st floor plan are compared with the planning concepts considered at early stage of the design. It can be said that the concept of hospital street and the spatial hierarchy should be carefully taken into account and tested the spatial configuration by the completed floor plan in order to satisfy the planning concepts.

센서 네트웍, 유비쿼터스 컴퓨팅 환경으로 발전하면서 스트리밍 데이터와 같이 무한한 데이터의 처리에 대한 요구가 많이 커지고 있다. 스트리밍 데이터에 대한 질의 처리는 크게 실시간으로 처리가 요구되는 질의와 과거 데이터에 대한 동향 근사치 요청질의로 나누어질 수 있다. 기존의 스트리밍 데이터 처리에 대한 연구들은 실시간 질의 처리만을 고려하고 과거 데이터에 대한 질의에 대한 고려는 미약하다. 그리고 사용자가 과거의 데이터에 대한 동향 분석을 요청하는 질의, 또는 과거 어느 시점의 데이터에 대한 요청 혹은 근사치를 요구하는 질의에 대해서는 처리를 할 수 없는 한계점이 있다. 본 논문에서는 스트리밍 데이터 프로세서의 메모리의 범위를 넘어서서 삭제되는 과거 데이터를 디스크의 I/O처리 속도에 맞추기 위해서 로드 셰딩 기법을 적용해서 저장한 후에 개념 계층을 이용해서 사용자가 원하는 데이터만을 효과적으로 저장하는 기법을 제안한다.

The purpose of this paper is to build a semantic networks of the 'cooking class' verb (based on 'CoreNet' of KAIST). This proceedings needs to adjust the concept classification. Then sub-categories of [Cooking] and [Foodstuff] hierarchy of CoreNet was adjusted for the construction of verb semantic networks. For the building a semantic networks, each meaning of 'Cooking verbs' of Korean has to be analyzed. This paper focused on the Korean 'heating' verbs and 'non-heating'verbs. Case frame structure and argument information were inserted for the describing verb information. This paper use a Propege 3.3 as a tool for building "cooking verb" semantic networks. Each verb and noun was inserted into it's class, and connected by property relation marker 'HasThemeAs', 'IsMaterialOf'.

본 논문에서는 정보의 중요도나 관련성의 정보에 기반한 퍼지함수를 적용하여 강제적 접근통제정책의 비밀성과 무결성을 보장하였으며, 보안등급을 이용하여 접근권한의 흐름을 통제할 수 있는 흐름정책과 역할그래프 생성 알고리즘을 제시하여 상속특성으로 인한 권한남용문제를 해결하였다. 또한, 상업적인 환경에 적용이 가능하도록 정보특성별로 역할을 그룹핑하여 역할계층을 구성함으로써 새로운 역할을 추가하는 것이 용이하여 다단계 보안시스템에서도 효과적으로 접근통제를 할 수 있을 뿐만 아니라 대규모 보안시스템으로 확장할 수 있는 장점을 갖는다.

Plant engineering industry is considered as a key industry which will drive the future of Korea. However, Korean plant engineering companies have recently made huge losses in overseas businesses and the lack of engineering capability is pointed out as a main cause of this situation. Unlike Korean plant engineering companies, world leading engineering companies such as Flour and Bechtel have their own systems Engineering Standards/Guides ensuring successful fulfillments of the concept and basic design processes. An engineering standard for an organization is an essential means to shorten the time for engineering design, to maintain the engineering quality and to secure the engineering efficiency in the development of the complex system. Korean plant engineering companies'lack of engineering capability comes from the absence of the engineering standard. In the paper, we have developed a steel-making plant engineering standard based on a systems engineering standard. We chose both ISO/IEC/IEEE 15288 and NASA SE Handbook as main reference standards. First, we have introduced a life-cycle definition and a physical hierarchy of a general steel-making plant. Then we have introduced detailed engineering processes of each life-cycle stage. The full scope of the study was from the feasibility study to the basic design but in the paper, we have only introduced detailed engineering processes and exit criteria for the feasibility study and the concept design.
