As the number of cars is rapidly increasing, we have to solve traffic jam. Therefore it is internationally developing IVHS(Intelligence Vehicle Highway System) to solve it. To extract the shortest path from road network, it need that digitized road network database construction, linked cost generation used road attribute and shortest path algorithm. In this paper, We extract twenty six intersections and roads between intersections from road network that extracts the central area of Chun-Chon city map with 1:25000 scale. And We make directed graph with these intersections which mapped nodes and these roads which mapped links. First, link cost be granted road length. Second, link cost be granted travel time of considering signal light at intersections. Shortest Path is extracted using link cost and appling Dijkstra algorithm.

연구목적 : 외환위기 이후에 급증한 노숙자 문제는 경제적인 상황의 호전에도 불구하고 만성화하는 경향을 보이고 있다. 쉼터의 노숙자를 대상으로 정신질환의 유병율과 삶의 질에 대한 조사를 시행하였다. 방 법 : 2000년 3월에 서울의 대표적인 쉼터에 거주하는 노숙자220명을 대상으로 인구학적 자료에 대한 설문조사를 한 뒤 Structured Clinical for DSM-Ⅳ(SCID-I)을 이용하여 AxisⅠ의 주요 정신질환을 진단하였다. 또 SmithKline Beecham Quality of Life Scale(SBQOL)를 사용하여 삶의 질정도를 평가하였다. 결 과 : DSM-Ⅳ AxisⅠ의 정신질환 중 기분장애, 정신병적 장애, 물질 사용 장애에 대한 진단 평가 결과 상기정신질환의 전체 평생 유병율은 73.6%, 현재 유병율은 59.1%이었다. 알코올 의존과 남용의 평생 유병율은 59.5%로 가장 높았고, 기분장애와 장애가 각각 39.5%, 3.6%이었다. 삶의 질은 노숙의 기간이나 실직 기간과 유의한 관계가 없었고, 자신이 지각한 건강상태, 자살과거력, 우울장애 유무와 통계적으로 유의하게 상관관계가 있었다(p<0.01). 결 론 : 노숙자에서 정신질환 중 알코올 장애의 유병율이 가장 높았으며, 우울장애가 있는 경우에 삶의 질이 저하되는 것으로 나타났다. Objectives : Homeless people surged after financial crisis tend to be chronic despite late economic recovery. So we tried to estimate prevalence of mental illness and quality of life of the homeless population living in shelter. Method : The study subjects were 220 homeless peoples who stayed at a shelter in Seoul around March 2000. Questionnaires on sociodemographic data were administered to the subjects, and then diagnoses of major DSM-Ⅳ Axis I mental disorders were made using Structured Clinical Interview for DSM-Ⅳ Axis I Disorders(SCID). And quality of life(QOL) was evaluated by SmithKline Beecham Quality of Life(SBQOL). Results : The lifetime prevalence of major DSM-Ⅳ mental disorders(mood disorders, psychotic disorder, and substance use disorder) of 220 homeless people was 73.6%, and current prevalence was 59.1%. The lifetime prevalence of alcohol dependence and abuse was highest, 59.5% and those of mood disorder and psychotic disorder were 39.5%, 3.6% respectively. Quality of life was not significantly correlated with duration of homelessness and unemploy-ment but marital status, self perceive health status, suicidal attempt history were significant factors. The quality of life in the people with mood disorders were estimated to be lower than those with any other diseases(p<0.01). Conclusion : Alcoholism was the most prevalent mental disorder in homeless people and mood disorder was negatively related to the quality of life scale.

The purpose of this study was to develop the environmental management strategy of streams based on the quantified evaluation method for the stream environment. The six streams in Jinju City flowing into the Nam-River were selected for case study. The stream environment evaluation was performed considering the following three independent field surveys. First, the stream naturalnesses considering 20 evaluation elements were investigated for each unit section of the streams having the length of 500m and the width of 100m, and then were evaluated into 5 grades. Second, water qualities of the steams were evaluated into 5 grades based on eight times of water quality survey for the period from July 2000 to September 2001. Third, the landuse patterns of the stream basins were evaluated into 5 grades according to the residential area ratio. Finally, the stream environments were classified into 5 grades considering the above three subfactors - stream naturalness, water quality, and residential landuse. According to the evaluation results of stream environments, the three environmental management strategies of streams were suggested. As the results of the case study, Panmun stream and Ghajwa stream were evaluated to forth grade that need active environmental restoration, and Nabul stream was evaluated to third grade that need partial environmental restoration while Youngchun river and Dogsan stream were evaluated to first grade showing the desirable stream environmental condition. The above environmental evaluation results for each stream will be an important reference for further stream restoration or management plan.

마스크 상의 거친 표면을 정의하기 위해서 Monte-Carlo 방법이 적용되었다. 극자외선 마스크의 거친 표면 함수, 즉 power spectral density 에 의해 표현된 무작위적인 표면의 높이 변화는 상면에서의 전기장을 계산하기 위해서 재정의 되었다. Feynmann의 접근 방식과 유사한 산란에 대한 일반식을 유도하였고, 이는 결상과정에서 마스크의 단차상의 거친 측면에 의한 효과를 알아보기 위해서 적용되어졌다. 거친 표면과 완전히 편평한 표면에 대한 전기장의 위상과 진폭 변화 정도를 비교하기 위해서 다중 산람 문제 또한 여러 다른 패턴에 대하여 이 논문에서 다뤄졌다. The Monte-Carlo Method is adopted to define the roughness of the mask structure. A random surface height variation described by power spectral density for the rough surfaces of an estreme ultraviolet (EUV) mask is to be redefined to calculate the field in the image plane. A general explicit formula of the scattering, which is analogous to Feynman's approach, is derived, and it is adapted to the EUV mask structure to evaluate the effect of the surface roughness of the side wall of the mask topography on the image formation. The multiple random scattering problems are dealt with the different pattern types in order to compare field variations in phase and amplitude with the ideal flat surface.

The mesenteric infarction, as a abdominal disease which show acute abdominal pain and almost need to emergency operation, has very high mortality. This mesenteric infarction has been reported very rarely. Also specific clinical manifestations are not clear, therefore initial diagnosis can be missed easily so that patients usually miss their opportunities for adequate treatment. Especially CAPD patients have high mortality because of their rareness and having similar symptoms like CAPD peritonitis. The authors report that the mesenteric infarction was miss-diagnosed to the CAF'D peritonitis with unspecific symptoms.
