This study aims to induce acoustic environmental characteristics which could be used for soundscape design by carrying out factor analysis on sound source image and cognition analysis on subjects' responses on selective questions due to class differences. The results of this study are as follows ; Satisfaction rate differences on exterior acoustic environment due to sensitivity and residence year were revealed. After factor analysis of living sound sources' image, it is known that natural sound, traditional sound, socials traffic sound, rural sound, religious sound and the others are main factors. Social traffic sound is the most one that should be eliminated and traditional sound is selected as a most Korean-like sound. Natural sound is evaluated as the most one that should be preserved and the most retrospectively one.

Salt attack is one of the serious deterioration factor with respect to the durability of concrete structure. Especially, in case of exposed rebar concrete structure in marine environment, corrosion of rebar is accelerated by penetration of $Cl^-$ from exterior. Through this path, volume of corroded rebar is increased about two and half times due to increased inner pressure originated from rust. As a consequence, the overall deterioration of concrete structure, namely, cracks, reduction of adhesive strength and pop-out is followed. In this paper, the effect of structure treatment of concrete on chloride resistance has been investigated. At the same time, the relationship among several characteristics, such as resistance to chloride, water absorption coefficient and surface hardness of concrete has been investigated. It is believed that surface performance improvement by the application of penetrative hardening agent influences on positively water absorption coefficient, surface hardness of concrete and resistance to chloride ion penetration.

Advancement in electronic technology has given office workers a new freedom, and a new meaning to workplace flexibility. Actually non territorial workplace has different space elements from general and conventional workplace in terns of interior design and architecture even organization management. The purpose of this study is on the establishment of an evaluation model for non territorial workplace that may be used, practically on the spot. For the establishment of non territorial workplace evaluation model, it is ahead of the study of the feature and the type of none territorial workplace and the research for existing office evaluation technique by Preiser and Vicher. And then the evaluation model for none territorial workplace which is composed three parts that is user's importance, provider's importance and user' satisfaction related fact of workplace. It is constructed by 6 factors which are physical, psychological, workplace environmental, communication, exterior environment, and space managing system therefore each factors has scrupulous elements therefore the total elements are 40. To make more confidence the evaluation model for non territorial workplace, it requires that study continually through the survey with the non territorial workplace evaluation model.

The purpose of this design plan is a method for opening the church to regional society to contribute to make up the community within regional society and to achieve the desirable common society of christianity like following. 1)For opening churchs to regional society, the church has to make up exterior spaces sufficiently. 2)The main chapel has to planned with mutipurpose for fiexibility and various functions of contemporary church. 3)The whole facilities have to be organized with a kind of the complex or multifunctional building which can accommodate activities of education, recreation and culture, therefore, content with the community's requirements. 4)The architectural form of the church has to planned with human scale, considering harmonization with regional environment. Modern church architecture needs a centralized plan, a variety of shapes such as square, round oval and polygon rather then a rectangular which is able to bring about a closer reationship between the priest and the congregation in the church.

Factors governing the rate of heat exchange comprise temperature, air velocity, relative humidity, and relation indoors. Recently, there are many researches on the transient analysis of indoor environmental factors such as dry bulb temperature, relative humidity and air velocity in miniature models. The purpose of this study is to measure the environmental factors and to analyze and evaluate the characteristics of indoor environment in different envelop structures using granite dome models. The interior relative humidity is constant regardless of exterior humidity although a little range of variation is shown in comparison to the cement model.

In this paper, the 3-D positioning problem for a quadruped walking robot is investigated. In order to determine the robot's exterior position and orentation in a worls coordinate system, a stereo 3-D positioning algorithm is proposed. The proposed algorithm uses a Guide-Mark Pattern (GMP) specialy designed for fast and reliable extraction of 3-D robot position information from the uncontrolled working environment. Some experimental results along with error analysis and several means of reducing the effects of vision processing error in the proposed algorithm are disscussed.

The purpose of this study is to suggest of facilities improvement and plan at children shelters. To this purpose, the researcher visited and interviewed users of three children shelters. To achieve a concrete goal of the study, (1) property room size per admitted children, (2) space satisfaction as bedroom, living room in a establishment, (3) facilities satisfaction as corridor, sanitation fixture. furniture (4) environment satisfaction as electricity, cooling and heating, ventilation, (5) exterior satisfaction as building image, color, landscape was analysed by interviewing. Based on the results of the analysis, a improvement for children shelters was presented.

In this paper, To estimate the train exterior noise and environment noise which are occur when High-Speed EMU is driving with the speed of 370km/h, Estimated sound source about noise that is appeared during operation based upon noise SPL values. Based on aero-dynamic noise source and wheel-rail noise source, these were already used to the existed research, we have estimated each sound power about measured noise, and computed the sound source to apply on the High-Speed EMU, and also calculated the sound power in case of the maximum operation speed of 370km/h.

The purpose of this study was to suggest fundmental data for facilities and the design of domitory building by investigating satisfaction of residents and their demands, grasping the present situation and the problem through the present of facilities and resident's actual condition. The object of this research were facilities and students using the domitory building of five universities. To analyze the data, frequncy, percentage, mean, one-way ANOVA and duncan-test were used by running SPSS $PC^＋$/ program. The major results are as follows. 1. There were differencies in the type of living space. the construction and furniture in the domitory building according to the five universities. 2. In using domitory building, five university students have significant differences. 3. There were significant differences in the satisfaction about exterior. interior and socio-psychological environment and the level of performance to the behavior.

A traditional Korean housing is a typical type which is contained life style, spatial organization and scape element of people who lived in Korea. In the hanok, people want to be live not only in human environment and traditional culture, but also modem urban housing as a high density. This article deals as follows: First, Hanok as urban housing would be composed in a housing lot, linear type layout, devide building, and cluster type. Second, Housing unit and configuration of Multi family housing can be used single story, second story, second story + single story, multi story and Hanok roofing. Thirds, structure of the building are traditional wooden, combined one of steel and wood or concrete and wood, and the building system in exterior and interior can be seperated into another system. Forth, Image of multi story Hanok A last, consistency of Hanok is not a repeat of an origin but application and creative aptitude of the origin, and multi family housing application of Hanok can be a trial creative.
