The objective of this study is to provide recommendations for the interir design of motor showroom as a sales policy. ten cases of motor showrooms were selected from already observed 50 showrooms in Seoul area. findings revealed that the car industries of Korea should meet the strong needs of differentiated sales policy, and the showroom design was an important factor which influenced client's pruchasing power. From these findings and analyses, this study suggests that each brand has to represent the typical total image to appeal to the consumer strongly . Additionally each showroom should be flexible in modification to meet the diverse conditions such as the location, required function and the trend of consumers. In conclusion , researchers provided 6 types of recommendations in terms of floor plan and interior elements such as circulation path, moduled furniture and objects color and lighting variation . Hopely, this research provides more functional and comfortable environment of automobile showrooms for consumers and companies.

Ondol heating, a kind of radiant floor heating, is a main method used in housing units in Korea. Building energy simulation including ondol and relevant facilities has not been performed due to its complexity. For evaluating energy consumption and indoor temperature variation, a new method should be proposed. At the present work, a dynamic simulation on ondol heating was tried by combining TRNSYS and EES. Characteristic functions for a pump, hot water coils and a gas boiler were simultaneously solved by EES, and calculated flow rates and supply temperature of hot water were provided as inputs of the active layer of TYPE 56 in TRNSYS. The results by the simulation on a typical housing unit in Korea shows a good trend in a viewpoint of actual behavior of ondol heating.

This paper presents the experimental results to verify the atomization characteristics and environmental impact of cutting fluid. Even though cutting fluid improves the productivity through the cooling and lubricating effects, environmental impact due to cutting fluid usage is also increased on factory shop floor. Cutting fluid's aerosol via atomization process can generate human health risk such as lung cancer and skin diseases. Experimental results show that the generated fine aerosol of which particle size less than 10 micron appears near working zone under typical operation conditions. The aerosol concentration also exceeds NIOSH regulations. This research can be provided as a basis of environmental impact analysis for environmental consciousness.

Crashworthiness design and certification have been and will continue to be the main concern in aviation safety. The effects of roll angles on fuselage section crashworthiness for typical civil transport category aircrafts were investigated. A fuselage section with waved-plates under cargo floor is suggested, and the finite element model of fuselage section is developed to simulate drop test subjected to 7 m/s impact velocity under conditions of 0-deg, 5-deg, 10-deg and 15-deg roll angles, respectively. A comparative analysis of failure modes, acceleration responses, and energy absorption of fuselage section under various conditions are given. The results show that the change of roll angles will significantly affect fuselage deformation, seat peak overloads, and energy absorption. The crashworthiness capability of aircraft can be effectively improved by choosing appropriate landing way.

The Wooden Stupa of Hwangnyongsa Temple, existed from Shilla to Koryo Dynasty, is recognized as a typical model of the Korean wooden stupa. The related records on this stupa are found in some historical documents including The Chronicles of the Three States ${\ulcorner}$三國史記${\lrcorner}$. This study, through the interpretation of these documents, attempts to discuss and analyse design and structural methods of the stupa, viz., i) the relationship with both Chinese and Japanese wooden stupa, ii) the height, iii) each floor's linking methods, iv) the 'Noban' (Basement of the upper part), v) structure of the 'Simju' (Central pillar) and vi) the stairs and the handrails. The results of this study would be hopefully used for the further researches as well as the restoration of this precious architectural asset.

This research considers the characteristics of the plan of the vernacular form of dwelling in KoCheon-Ri village, situated in the Yong-Dong mountain region. As part of this study, an analysis of local diversity is carried out. The current existing village houses in Kocheon-Ri can be categorized according to their floor structure, either as a wooden-floored or an Ondol-floored Kyup-jip(a double row house type). It was found that the wooden-flooded Kyup-jip house has been transformed into Ondol-floorded Kyup-jip due to a range of various factors. In order to clarify the characteristics of the vernacular dwelling type occurring in a particular area, it is important to determine the typical form that appears within the broader area. However, differences is also essential.

On September $11^{th}$ 2001, the twin towers of the World Trade Center in New York City were struck by two hijacked airplanes. Despite severe local damage induced by the impact, the towers were able to sustain 102 and 56 minutes of the subsequent multi-storey fires before collapsing. The purpose of this study is to contribute to the understanding of the in-fire performance of composite trusses by examining the behaviour of the longer-span type used in the towers. It makes no attempt to be a forensic study of the actual events. Using the finite element package Vulcan, the structural mechanics of typical long-span composite floor trusses are explained, under a variety of scenarios, as the fire temperatures rise. Different boundary conditions, degrees of protection and loading are all covered, the results being presented mainly in the form of graphs of deflection and internal force of members against time.

The authors observed typical skin form of avian staphylocorcosis in 12 day-old-chickens which were kept on the floor. The lesions observed were edematous, necrotic and crusty dermatitis on the wings, the head, the neck and the other parts of the body. Delta hemolytic type Staphylococcus aureus and Herellea were isolated from the lesions of each bird examined.

The purpose of this study was to examine the current interior conditions of internal medicines and the patients'responses to them. Data were collected through questionnaire survey including observations and interviews. The sample consisted of 43 internal medicines in Busan. The data were analyzed by using SPSS-PC. The major findings were as follows: (1) Most of the medicines had a size of 20-50 pyung(66-165$m^2$). The preferred size of internal medicine was 30-70 Pyung. (2) The typical layout of reception room, doctor's room, and injection room was L shape. (3) The most preferred room was waiting room and the worst one was injection room. (4) Painting and tile were mostly used as interior finishing materials. The patients preferred wall papers as wall and ceiling material, and marbles as floor material. Also, the most preferred interior images were modern, western, urban, open, simple, warm and popular images.
