Population of senior citizens in Korea has been on the increase rapidly through decrease in population by falling birth rate and extension the average life span by development of medical technology and improving people's standard of living. As the booming population of senior citizens, it has appeared to problems of the elderly such as protection, health and supporting and welfare facilities for the elderly have increased there but it leaves something to be desired at plan and improvement of qualitative environment which the elderly's living space. It attaches importance to valuate about nursing homes such as management, quality of service, manufacture of physical environment and so on, so it is required to consider the elderly's emotion on environmental valuation. Healing environment that is a important fact of indoor environment operates powerfully upon the nursing homes as well as general medical facilities. It needs to healing environment for the elderly's physical health and mental stable life, we should know importance of healing environment that affects the elderly's health and life. The elderly have experienced physical, mental, and social changes with advancing years. The people who use the nursing homes are the elderly. We should find fact of healing environment as the elderly's characteristics and have to find healing environment that gives aid to the elderly's health in the nursing homes. In care for the elderly is not house care, it has focused on the elderly's health for improving their life and leading comfortable life.

User-oriented Design is necessary in planning the interior design of Metropolitan Railroads trains, since this is a typical means of transportation in this modem society and all ages people with different body scale use this facility. However, there are little studies about facility panning and zoning of Metropolitan Railroads train considering users. Therefore, in this study, after completing the checklist based on the current legal standards of facility installation of South Korea and Japan, we examined user's facility and suggest several improvement of the opening 14 metropolitan railroad lines in Seoul. Then, we evaluated this facilities according to 41 standards; general facility(24 standards), safety facility(4 standards), guide facility(11 standards), other facility(4 standards). The result of this study may be summarized as follows. 1) General facility has to be designed to obtain lots of room for storage and this facility should be fixed up tightly with secure system. 2) Safety facility should be designed to minimize a difference of floor-level between threshold of train and ground. Also, using various color and material could help passengers to distinguish different space and facility. 3) Guide facility should be designed to guide passengers to the accurate direction with proper sign design in the pathway of Metropolitan railroad train. Also, more various color, which based on the research about physiological and psychological effect, should be used to guide people. 4) Other facility should equip more visual system using common good and informative contents. Through this study, we try to understand the current interior physical condition of Metropolitan Railroads trains. However, for future studies, it is expected to supplement evaluation standards considering aesthetic design, environmental improvement of indoor air quality and the satisfaction and demand of Metropolitan Railroads trains.

Ubiquitous location based services (u-LBS) will be interested to an important services. They can easily recognize object position at anytime, anywhere. At present, many researchers are making a study of the position recognition and tracking. This paper consists of postion recognition and user identification system. The position recognition is based on location under services (LBS) using a signal strength map, a database is previously made use of empirical measured received signal strength indicator (RSSI). The user identification system automatically controls instruments which is located in home. Moreover users are able to measures body signal freely. We implemented the multi-hop routing method using the Star-Mesh networks. Also, we use the sensor devices which are satisfied with the IEEE 802.15.4 specification. The used devices are the Nano-24 modules in Octacomm Co. Ltd. A RSSI is very important factor in position recognition analysis. It makes use of the way that decides position recognition and user identification in narrow indoor space. In experiments, we can analyze properties of the RSSI, draw the parameter about position recognition. The experimental result is that RSSI value is attenuated according to increasing distances. It also derives property of the radio frequency (RF) signal. Moreover, we express the monitoring program using the Microsoft C#. Finally, the proposed methods are expected to protect a sudden death and an accident in home.

국내외적으로 위치정보를 이용한 다양한 위치인식 기반의 지능시스템에 대해 활발한 연구가 진행되어 왔다. 대표적인 점대다점 통신 기반의 위치인식 기법은 TOA(Time Of Arrival)를 이용하여 위치를 인식하고자 하는 노드까지의 거리를 계산하고, 3개 노드들의 위치정보를 삼각측량법에 적용하여 고정노드의 위치를 인식하는 기법이다. 따라서 점대다점 통신 위치인식 기법은 사전에 시스템이 특정 공간에 설치되어 있어야 하는 점과 시스템 구축비용이 필요하다는 단점이 존재한다. 본 논문에서는 이러한 점대다점 통신 위치인식 기법의 단점을 보완하기 위한 레인징 기반의 점대점 통신 위치인식 기법을 제시하고, 점대다점 기반의 통신 위치인식 기법에 대비한 성능을 평가하고자 한다. 이를 위해 실내 환경에서 레인징 기반의 점대다점과 점대점 통신 위치인식시스템을 각각 구축하여 실험하였다. 실험 결과 제안된 점대점 위치인식을 적용한 기법이 기존의 점대다점 위치인식을 적용한 기법에 비해 위치인식 정밀도가 3배 이상 향상됨을 확인할 수 있었다.

In an apartment house that is generally air-tight and well insulated, the combustion gas from cooking devices is the major source of air pollution in the kitchen. It spreads throughout the house affecting the overall Indoor all quality. In this study, the performance of the kitchen range hood which employs air induction and air curtain was investigated by numerical simulation. The results are compared with that of two other kitchen range hoods which are in general use. The two general types of range hoods considered in the present calculations are box and plate type range hoods. The former has a large capture space between the filter and suction duct, while the latter has little. It was found that the capture efficiency of the kitchen range hood with air induction and air curtain Is higher than that of the general types of range hoods by 20% approximately The reason may be because the air induction and the air curtain block the air stream escaping from the front and the side part of range hoods effectively and because an additional fan for air induction and air curtain increases suction flow rates.

We studied in order to find out suitable amounts of board by visual effects to establish indoor boards and human psychological effects by several board designs. Thirty students of C university were tested in constant temperature/humidity room and interviewed after tests. The experimental visual images were projected from 54' TV. As a result, the board length that showed high preference and satisfaction was the 90cm both horizontal and vertical direction. We found that vertical board gave an impression of a linear and narrow shape and the horizontal board gave wide space and cool feeling from psychological analytical study. The factors affecting satisfaction in horizontal direction were refreshing, intimacy, beauty, area, splendor and those in vertical direction were a sense of security, beauty, texture, intimacy, continuity, extensity, natural feeling. We got 5 factors from the result of factor analysis in order to get psychological factor axis. Those were pleasantness, artificiality, openness, dynamics, refinement. By multiple regression analysis, the factor pleasantness had the highest impact on visual satisfaction on scenary. The study on psychological factor difference by analysis of variance showed that psychologically feeling amount about pleasantness, artificiality, dynamics, refinement, and openness had statistically meaningful difference despite of board direction. We found that the 90cm had a tendency as a changing point leading image change by the investigative analysis of board direction based on factor points.

This study is aimed to be used as basic data to plan Korean style cohousing for double-income families in the future by studying their lifestyle, housing needs and housing awareness on cohousing. The results of the study are as follows. 1) As for the life style of the subject families, it was a housewife that mainly does the household affairs despite of the status of double-income family. Also, as for the social activity, almost half of the respondents said that the spending in child-care facilities was not sufficient and wanted to send their children to ones within their neighborhood. 2) As far as housing awareness on cohousing concerned, among specific items, the child care area, the household affairs division area, and participatory awareness of residents in housing planning and management got higher scores, while as for awareness on utilizing common space, using the common hobby rooms, promenades and benches, exercise facilities, common yard, and study rooms got higher scores. When asked about the necessity for cohousing in Korea, they gave very positive answers, but the answer to their willingness to reside in it was less positive. 3) Summarizing the housing needs on cohousing, it turned out that more people wanted to reside in suburban area with others having common grounds with them as for a desirable residence environment. They wanted the neighborhood to be composed of 10${\sim}$29 families, and medium-density semi-detached house occupied by owners. They wanted a mixture of independent management and entrust management for managing common facilities, and common meal once a week. They wanted indoor exercise facilities to be more extended than other common facilities, and the house of $100m^{2}{\sim}130m^{2}$ with 3 bedrooms, 2 bath rooms, and a large living room and dining room.
