The modern society longing for the convenience of up-to-date technology, there are attempts of miniaturization and high reliance of power equipments in the effectiveness aspect of urban area's usage of space while requiring more electrical energy than now. Consequently, paper used to the Neral Network for a forcasting conservation system. A neral network is powerful asta modeling tool that is able to capture and represent complex input/output relationships. The true power and advantage of neral networks lies in their ability to learn these relationships directly from the data being modeled. Traditional linear models are simply inadequate when it comes to modeling data that contains non-linear characteristics. Form results of this study, the Neral Network is will play an important role for insulation diagnosis system of real site GIS and power eqipment using $SF_6$ gas.

Street furniture such as benches, streetlamps, and shades which are easily accessible in cities has contributed to the promotion of active, lively environment for people living in cities. Furthermore, they make the characteristics of specific regions and cities, and are valued as a communication interface to restore the relationships between people and cities. The street furniture design with inherent publicness is an essential element for leisurely life and refined image of modern people who have experienced severance and mental poverty in uniform, vertical modern city space with the development of advanced science and technology. The purpose of this study is to analyze the new design approaches to street furniture which plays an important role in the determination of the images of modern city environment and to examine the characteristics and trends of such designs. First, in accordance with the flow of studies from publicness and public space to street furniture, the concept and meaning of publicness which is the basic element of public space were identified through theoretical examination, and the characteristics and roles of modern public space were analyzed through literature review, data review, and international cases. Based on the results of this theoretical analysis, the concept and meaning elements, function elements, and design elements of the street furniture which was planned in accordance with the goal and functions of public space were identified. For the meaning elements of street furniture design, fun, health, culture, sustainability, and vitalization were identified. For the function elements of street furniture design, convenience, safety, and delivery were identified. As the characteristics of modern street furniture design, convergent, green, digilog, functional, and universal designs were analyzed. This study is meaningful in that it recognized the roles of street furniture in modern public space as a concrete, practical environmental design element and estimated the development directions of street furniture design in public space.

Recently, character motion have been used extensively in the entertainment business, and researchers have investigated algorithms of reproducing, editing, and simulating mimic human movements. Also, many recent researches have suggested how a character interacts with its surrounding environment in terms of motion. Specially, spatial relationships of the environment have been introduced for adapting and preserving character motion. In this paper, we propose a motion adaptation technique preserving a spatial property between a virtual character and the configuration of its surrounding space. Additionally, we report on experimental results of smoothly adapted motions in various environmental structures with original motions such as walk, jump, and tumbling.

Multi-family housings caused several problems related to physical form such as isolation of housing estate, inhumanity of the exterior space, and mismatch with the urban structure. To handle these problems, the purpose of this study is to analyse density elements which have a direct impact on physical forms, thereby understand the characteristics of physical form and also identify a meaning of inter-relationships between them. Therefore both formal constituents and density elements are reformed into respective analyzing indices. From the analysis, physical form and the spatial layout of buildings were more uniform in large-scale housing estates than in medium or small housing estates. However, small-scale housing estates showed various form and the spatial layout of buildings in order to increase the building density.

Background: Although the paramedian approach for epidural blockade is useful in some clinical situation, the parameters which are correlated with the distance from skin to the epidural space has not been established. Methods: We studied in 143 patients having elective continuous epidural blocks for relief of postoperative pain. All blocks were performed using paramedian approach with Tuohy needle in the lumbar (group 1, n=100) and thoracic (group 2, n=45) area. We measured the distance from skin to the epidural space, body weight, height, and the angle between the shaft of the needle and the skin. Data were analyzed by linear regression. The relationships between parameters identified by the F-test with a P value of less than 0.05 were considered statistically significant. Results: The mean distance from skin to the lumbar epidural space was $4.4{\pm}0.7$ cm. significant correlation between the body weight and the depth of lumbar epidural space ($\gamma$ value : 0.492) was noted with regression equation of depth(cm)=2.293+0.034${\times}$body weight (kg). Also the significant correlation between the ponderal index (PI) and the depth of lumbar epidural space ($\gamma$ value : 0.539) was noted with regression equation of depth(cm)=1.703+0.07${\times}$PI, The mean distance from skin to the thoracic epidural space was $5.2{\pm}0.7cm$ which did not correlated with other anatomic measurements. Conclusion: We found that PI and body weight are the suitable predictors of the depth of the lumbar epidural space, but not the thoracic epidural space.

2000년 공공도서관에 대한 정보화 사업의 일환으로 디지털자료 전용공간이 대다수의 도서관에 마련되었지만 획일적인 디자인으로 인해 이용자의 다양한 행위를 수용하기에는 부족한 실정이다. 본 연구는 공공도서관 디지털공간의 공간계획요소에 대한 문헌 및 설문조사를 통하여 디지털 세대 이용자의 새로운 요구에 대응하기 위하여 공공도서관 이용자가 정보활동 시 중요하다고 생각하는 공간계획요소에 대한 중요도평가를 실시하였다. 중요도 평가를 위하여 1차적으로 각 기관의 도서관 기준 및 평가지표, 선행연구를 분석하여 50개의 요소가 도출되었고 이를 이용자 150명에게 설문조사 하였다. 중요도의 평균값 이상 도출된 요소를 중심으로 요인분석을 실시하였으며 비슷한 성격의 요소들 간의 상관성을 파악하여 요인별 공간계획요소를 분류하고자 하였다. 연구결과 계획적요인, 디자인적요인, 심리적요인, 기술적요인 총 4개의 요인으로 분류되었다. 이와 같은 요인별 디지털공간계획요소들을 평가도구로 하여 차후 공공도서관 공간평가와 이용자 만족도 조사를 실시함으로서 구체적인 공간계획방안 마련에 기초자료가 될 수 있을 것이다.

Computer-mediated communication(CMC) media has various forms through the technical improvements of computer and network, and CMCs communication methods are also comparative free rather than any other existing media without the limitation of time and space. Various CMC media were adopted by a lot of organizations for their communication tool. Thus, it is important to understand relationships of affecting factors to user's communication satisfaction for choosing the effective CMC media in their organizations. In this paper, we identify factors that may affect the communication satisfaction of users that has utilized the CMC media, and validate empirically the relationships between the identified factors in KOPTI. In the research model developed and described herein, perceived media richness was significantly associated with communication satisfaction and perceived usefulness was significantly associated with perceived media richness. Furthermore, perceived ease of use was significantly associated with perceived usefulness.

When we want to find out the regulatory relationships between genes from gene expression data, dimensionality is one of the big problem. In general, the size of search space in modeling the regulatory relationships grows in O(n$^2$) while the number of genes is increasing. However, hopefully it can be reduced to O(kn) with selected k by applying divide and conquer heuristics which depend on some assumptions about genetic network. In this paper, we approach the modeling problem in divide-and-conquer manner. We applied clustering to make the problem into small sub-problems, then hierarchical model process is applied to those small sub-problems.

본 논문은 홍콩 영화감독 왕가위의 작품에서 현실, 촬영, 서사로 구성된 공간 표현과 그러한 공간이 홍콩의 도시문화, 인식 및 사람 간 관계에 어떻게 영향을 미치는지 분석한다. 왕가위 감독의 영화를 분석하기 위해 찰스 샌더스 퍼스의 기호학 개념과 폴 비릴리오의 공간 개념을 적용하였다. 이를 통해 왕가위 감독의 영화 공간에 내포한 의미가 어떻게 영화 성공의 중요한 요소가 될 수 있었는지를 살펴보았다. 왕가위 감독은 주제 표현에서 사회가 형성한 인륜이라는 가치에 초점을 맞추어 인간 정신세계를 직접적으로 표현하며 관객들로 하여금 그에 대해 사고하게 하였다. 이 논문에서는 왕가위 감독의 영화에서 표현한 공간을 공공, 개인 그리고 연결공간으로 구분하여 홍콩 젊은이들의 주거 환경과 정서를 보여주는 수단으로 분석하였다. 이를 통해 왕가위 감독의 영화 속 공간 표현이 홍콩 시민 의식의 동서양 문화와 사회적 연결 지점에서 문화 해석 기능을 잘 보여주고 있다고 판단하였다. 결론적으로, 왕가위 감독의 작품은 동시대 사람들의 삶과 감정, 도시 공간에 대한 풍부한 이해를 제공하며, 홍콩의 영화 산업과 문화적 가치에 대한 중요한 통찰력을 제공하고 있다.
