In a turn a century, the skepticism, mysticism and eroticism used to prevail, the people becoming anxious, expectative and doubtful about an oncoming age. The costumes tend to become more exciting and erotic in the fashion. This thesis is on understanding “What would 21 century's clothes be\ulcorner” after analyzing the specific points in an end of the century. The characteristics found from 16th century to 20th century are going to the extremes in the shapes, consistent appearance of bustle style costumes and excessive ornaments which are closely interrelated with one another. I expect the fashion in 21st century would be changed in two ways. Firstly, going to the extremes and stressing on the buttock would be going down in the end of 1999. Secondly, the comfortable clothes highest in function and technology, and also friendly to the environment, might be the main stream, rather then outwardly good looking clothes, because spirit and environment is much more emphasized than the mode by the social impact or pressure in the next era.

Today, augmentation of industrial wastes with industrial development demands diminution and recycling technical development for industrial wastes reduction. A statistical research of industry and constructional wastes as a request of the times can achieve the conservation of resource and the protection of environment. The ultimate object of the study is not only diminution and recycling of industrial wastes but also the degree of self-sufficiency in resource and the attainment of comfortable life environment, which can the accomplish the resource circulation system and make progress into the environmentally advanced country. The object of this investigation is industrial classification, a waste discharge quantity, a waste sort, waste disposal of industrial wastes in Yeung-nam area. The investigation of special quality in industrial wastes can be used to establish a wastes management policy and a disposition method .

The existing building code regulates the minimum distance between buildings and the minimum required sunshine hours for winter solstice to ensure the right to light. Especially, the minimum sunshine hours have been guaranteed by the constitution after the right for the people to live in a healthy and comfortable environment was established. However, the existing regulation on the sunshine hours only considers the duration of sunshine hours, but ignores the minimum amount of sunlight. Therefore, the calculated sunshine hours are not coincident with the hours occupants actually feel. Therefore, the purpose of this study is to investigate the effect of solar incident angle on interior illuminance distribution, which will be used to propose a new code on the minimum sunshine hours and levels.

Sustainable interior design elements are related with human health. We know that a demand for environmental-friendly housing and all about the others demanding are for human health. We have to make up basement of natural environment for sustainable space composition. If natural environment is polluted that surrounded by human, we have to effort to revive without any pollution. We have to get accomplished stability, comfortable, security, convenience and organize interior design elements for sustainable space to enhance for the quality of life. Furthermore, it needs to get a respect lifestyle on personal. To study composing of the sustainable interior design, we arranged interior design elements to compose sustainable space of housing. We investigated how to compose energy-efficiency, sustainable, interior tree-planting, alterable of the space.

The visual environment in an educational building, apart from providing the comfortable seeing conditions needed for the performance of a wide variety of work tasks, must also satisfy the psychological and emotional needs of learners. This paper presents study on actual illumination environment of college and comparison of economical efficiency in order to figure out illumination problems. Furthermore, it attempts to suggest an optimum design of lecture room illumination through computer simulation. We try to evaluate economical efficiency of lighting design in lecture room under the illumination plan which is based on illumination maintenance and uniformity ratio that KS. illumination standard sets.

Indoor climate control equipments is used to make the indoor environment more comfortable when indoor condition is not satisfactory to inhabitants. In this study, which instrument is preferred to control indoor climate and which is not preferred were surveyed with questionnaire. With this result, the needs of dwellers and wanting performance of housing could be revealed. Results are followings 1) The satisfaction ratio and equipment possession ratio of apartment houses' is higher than that of detached dwelling's 2) It is recognized for inhabitants that air cleaner is the mostly used equipment and best equipment for indoor comfort. 3) Electronic fomentation mat is recognized as the most problematic equipment for securing inhabitant's comfort. And air conditioner is considered negative for 60% of responser's. As grow older, this trend is increasing.

Sound and vibrations enter every aspect of our daily lives. Some, like music and verbal communications, soothe and relax us; others, such as the noise and vibration from traffic or machinery, can threaten our well being. The Rion Co., Ltd. was eslablished in 1944 as an affiliate of physics and acoustic pioneer, Kobayashi Institute of Physical Research. The RION lineup affords a full line of easy-to handle measuring, recording, and analyzing equipment with innumerable applications for monitoring and maintaining a comfortable environment. RION's concern takes in all manner of sound and vibration. Our activities extend from measuring reverberation time in concert halls and testing the soundproofing characteristics of housing materials to the control and maintenance of machine noise and vibration levels.

본 연구는 돼지의 체온 발산에 따른 행동에 근거하여 환경을 제어할 때 몸체에서 발산되는 체열과 환경의 온도차이를 이용하여 환경을 제어할 수 있는 방법을 모색하고자 하였으며, 열환경에서 얻어진 자료를 바탕으로 축사의 환경제어 시스템에 접목하고자 실시하였다. 연구의 결과를 요약하면 다음과 같다. 1. 환경온도에 따른 돼지의 행동을 칼라영상을 통하여 획득한 후 가시화 시스템 (열화상 프로그램)을 통한 행동상태를 고온, 적온, 저온기로 분류하였다. 2. 영상처리 시스템의 하드웨어를 적외선 CCD 카메라, 영상처리 보드DIF(TH3100) 모델과 컴퓨터는 400Hz, 128M, 586 Pentium로 구성되었으며, 프로그램은 C++ 언어로 작성되었다. 3. 영상처리시스템을 온도에 따라 분류했던 결과 저온, 적온, 고온으로 분류되어 돈사내 환경제어 시스템에 응용이 가능할 것으로 판단되었다. 4. 사료섭취량은 저온구가 다른 환경온도에 비하여 사료를 많이 섭취하였던 반면에 종료체중과 일당증체량에서는 낮게 나타났다 (p<0.05).

Purpose: It is crucially important that indoor luminous conditions of built environments be carefully studied so as to promote comfort and occupants' well-being. Method: The current study therefore focuses on the lit aspect of an enclosed space considered to be a resting room ($4.5m{\times}6.32m{\times}2.5m$). Particularly, on the effect that light levels and light color temperatures have on the physiological and psychological responses of resting occupants. To do so, a questionnaire survey was carried out on 50 subjects. The independent variables for the experiment included 9 different luminous environment conditions setup using 3 different levels of illuminance (50 lx, 150 lx, 300 lx) and 3 different color temperatures (2000 K, 3800 K, 5600 K). A questionnaire was utilized in determining which conditions were preferred by occupants. Result: As it turns out, indoor luminous environment designed for relaxation purposes should display luminance levels of at least 150 lx and 3800 K of color temperature in order to provide a visually comfortable environment suitable for the occupant's relaxation while at the same time promoting the psychological and HRV well-being of resting occupants.

Korean Traditional houses has been evolved and developed in many years, adopting the natural environment to control exterior conditions. These control method are various passive system of using natural materials, considering micro climate, building lay out, and these system are more natural and ecological to make the comfortable indoor climate than active systems of the present houses. This study aims to analyzed control performance of outdoor environment of five Korean traditional houses during the summer and winter. These houses are varied with lay out and floor plan to reflect the way of control for environmental condition, surveyed the reverberation time and sound level difference between rooms of the main living room and other main floored room, master room and kitchen. Especially air temperature and humidity have been measured simultaneously in each rooms to compare with outdoor condition. As a result, the variation of air temperature and humidity of most rooms are considerably static while condition of outdoors are much varied, it is showed that indoor climate has been controled with traditional soiled walls.
