This study aims to propose the future plan and research management of a beach and the relation between spatial structure of a village and layout of the beach focusing on Gimnyeong beach among the 12 general beaches in Jejudo. The results are as followings: First, Gimnyeong beach had the relation to primary industries of residents in the village in times past and was the space for everyday lives of residents. However, at present it has the relation to tertiary industries and is more important in community activities. Second, the entry part and the sandy beach of Gimnyeong beach were crucial in location and function in times past but total size of the beach has expanded for campground nowadays. Therefore, it is necessary to change the location of entry part to center part of the beach. In addition, convenient and safe facilities are need to be built more to corresponding to expanding area of the beach. Finally, in order to maintain clean sea, residents in the Gimnyeong have agreed to not make sea farms in the vicinity of Gimnyeong Beach which pollute the sea. Their roles have influenced on positive effect to community of the village, management of the beach, and maintenance of clean sea.

This paper aims at the development of an knowledge base for an electrical fire cause diagnosis system using the entity relation database. The relation database which provides a very simple but powerful way of representing data is widely used. The system focused on database construction and cause diagnosis can diagnose the causes of electrical fires easily and efficiently. In order to store and access to the information concerned with electrical fires, the key index items which identify electrical fires uniquely are derived out. The knowledge base consists of a case base which contains information from the past fires and a rule base with rules from expertise. To implement the knowledge base, Access 2000, one of DB development tools under windows environment and Visual Basic 6.0 are used as a DB building tool. For the reasoning technique, a mixed reasoning approach of a case based inference and a rule based inference has been adopted. Knowledge-based reasoning could present the cause of a newly occurred fire to be diagnosed by searching the knowledge base for reasonable matching. The knowledge-based database has not only searching functions with multiple attributes by using the collected various information(such as fire evidence, structure, and weather of a fire scene), but also more improved diagnosis functions which can be easily wed for the electrical fire cause diagnosis system.

In order to study and obtain the mathematical relation between the electrification degree of transformer oil flow and the electrostatic current, a small amount of data about the electrification degree of oil flow and the corresponding electrostatic current is studied by linear regression method and grey model method. The results show that the linear correlation between the electrification degree and the electrostatic current was not good, and the relation between the electrification degree of oil flow and electrostatic current (i) could be expressed as ${\rho}(0)=0.2049\;i^{(0)}+169.4419$ according to grey model GM (0, 2) when the electrification degree of oil flow is represented by the charge number generated from transformer oil per unit volume, namely the charge density (${\rho}$).

The purpose of this study is to analyze the interior characteristics of the Yale center for British art by Louis I. Kahn. As his last realized project, the Yale center for British art shows Kahn's latter architectural thoughts about exterior/interior, space/structure and theory/practice. Kahn arranged unit space(room) around two interior courts and laminated them vertically. This spatial configuration is the result of solving the urban context which needed the continuity of street and complicated program including art museum, retail shop, studio and library. Although Kahn adpted severe formal configuration, he added changes to spatial relation. The visualization of architectural system is realized by revealing the relation of the unit space and structure. And this emphasized the presence of the center. The emphasis of tectonic expression is also the characteristics of interior in that structure is the logical part of whole building system rather than concealing object for the exterior of buildings. In the Yale center for British art, interior characteristics are summarized as spatial configuration based on the relation between unit space and two courts, the visualization of structural order, and the relationship between structure and light.

그 동안 정부기관은 소위 대민홍보를 중심으로 하는 일방향적 커뮤니케이션 구성과 방식에 익숙해져 있으며, 이로 인해 정부의 공공정책에 관심을 가지고 이를 이해하고 적극적으로 참여하는 수용자들의 태도가 극히 드물었던 것이 사실이다. 그러나 스마트 단말기의 폭발적인 보급으로 인해 정부기관의 공공정책에 대한 PR 방식이 SNS, 어플리케이션 제작 등으로 다각화되고, 이를 통해 관련 정보에 대한 수용자의 이해도는 물론 참여를 적극적으로 높이는 계기를 맞이하고 있다. 이와 같은 배경에서 본 연구는 정부 등 공공기관이 SNS를 통한 PR 캠페인 활동을 좀 더 효율적으로 구성할 수 있는 방안을 모색하고자 국내 및 미국의 사례를 통해 정부정책 신뢰도 제고를 위한 SNS 전략의 유형과 특징을 살펴보고 이에 대한 함의를 찾고자 했다.

Objectives : Acquiring information from symptoms is one of the important method to gain clinically available information in korean medicine. Therefore, up to now, study of symptom terms was frequently implemented in promotion of various information project. In data extraction methods using symptom information from DB, information search using synonym and method using ontology is studied and utilized. However, considering concept of symptom has essential information of appeared body area and phenomenon we think that extending synonym and ontology relationship in symptom terms can be useful for search and set to this study. Methods : We collect terms relevant to human body area and structure described in Donguibogam. Synonymous relationship between collected terms is organized. Relationship between collected terms is build to human-body-knowledge table which has form of Concept+Relation+Concept. Type of relationship is limited on a range of expressing content about parts of human body. Result & Conclusion : Search condition is generated automatically using relationship of the upper area in knowledge table contents. Information of next and previous acupuncture point, upper and lower acupuncture point, left and right acupuncture point can be searched using information of acupuncture point location, order, relative position in area, direction in knowledge table contents.

The purpose of the present study was to examine the relation of total antioxidant status (TAS) to metabolic risk factors in Korean adults. Anthropometric measures, blood pressure, serum lipids and fasting glucose were determined in 406 men and women. TAS was measured by using commercially available Randox kit. Serum TAS was significantly positively correlated with body weight (p=0.004), body mass index (BMI) (p=0.033), waist circumference (p=0.017), total cholesterol (p=0.038) and triglyceride (TG) (p<0.001). The mean TAS of hypertriglyceridemic subjects (TG ${\geq}$150 mg/dl) was significantly higher than that of subjects whose TG was lower than 150 mg/dl (p=0.001). When central obesity, TG, high density lipoprotein cholesterol, fasting glucose and blood pressure were considered as metabolic risk factors, TAS was shown to be elevated with increased number of metabolic risk factors (p=0.004). The positive association between TAS and a number of metabolic risk factors suggests that increased TAS may not always indicate one's healthier condition. In order to help understand TAS as a marker of total antioxidant capacity in humans with various metabolic conditions, it is needed to clarify the factors affecting TAS in relation to changes in metabolic risk factors.

Effects of forging and mechanical properties of 6061 aluminum alloy wheel for automobiles were investigated in the present study. Microstructural and tensile characteristics of automobile wheel after hot forging process using dynamic screw press were analyzed to evaluate effect of metal flow on mechanical properties. The results showed advanced mechanical properties of 6061 alloy wheel because of $Mg_2Si$ precipitation by T6, elongated grain by forging, and work hardening by dense metal flow, etc. Hot compression tests were conducted in order to characterize high temperature compression deformation behaviors and microstructural variation in the range of $300{\sim}450^{\circ}C$, in the strain rate range of $10^{-3}{\sim}10^1\;sec^{-1}$. As strain rate increased, maximum compression stress increased but it was shown the reverse linear relation between temperature and maximum stress irrelevant to strain rate variation. On the other hand, temperature and yield stress didn't have any linear relation and its relation showed big deviation by a function of strain rate and test temperature.
