In case of the large-scaled indoor gymnasium that has been constructed in the local area, there are many instances for the use as multipurpose space where the public performances are possible such as leisure activity, lecture, assembling activity, drama, concert and so on for the resident together with the purpose of sporting facility. In order for utilization to the maximum of the function of such indoor gymnasium, the acoustic capabilities concerned with Definition of both Voice and Music are simultaneously required. However, in case of the large-scaled athletic facility, since it was designed with high ceiling-height in view of its characteristics, it forms a Sound Focus and then the sound is concentrating to the specific part, and because the vibration of sound is too loud due to its broad volume, the acoustic defects such as many Echoes are arising. On such viewpoint, based on the drawing of the indoor gymnasium that is scheduled to be built at B County, Chonbuk Province, this Study has proposed such indoor gymnasium equipped with the optimized acoustic condition passing through Acoustic Simulation Phase. As the result of Acoustic Simulation, we could design the indoor gymnasium that equipped with really satisfying acoustic performance 'after' reformation compared with 'before' reformation, and it is considering that such material could be utilized as the fundamental material that brings a curtailment effect of the construction cost and also enables us to improve the acoustic performance, at the stage of planning and designing for the similar sporting facility in the future.

A new movement in forming community villages for better living standards is becoming popular. In order to sustain a proper community, it is essential to design proper community programs and facilities, which can encourage the proactive participation of residents. In this study, detailed aspects of the Mindlre (Dandelion) community (including formation process and management of the village) are investigated. The Mindlre community is a successful community village in Korea concerned with residents' participation and community activities. The community is located in Sancheong, Gyungsangnamdo province in Korea. The study methods are references, field trips, and interviews with residents. Six areas were surveyed and investigated: the physical environment of the Mindlre community and eco-friendly elements, respondents' background and the motivation to join, residents composition, residents' participation in the formation process of the community, self-management systems and common activities, and residents's life satisfaction. The mindlre Community was founded on Christian religions faith. The primary idea of this village was building a new hope for rural areas without discrimination. The size of the village was expanded with housing for teachers and students who were linked with the Mindlre School (substitution school). When the community was founded, existing shapes of the village were preserved. The village was physically renovated based on the original environment, in addition nature friendly materials and methods were used. The residents were proactively involved in the community through regular meetings, self-regulation, and community worship. Although the survey results should that most residents were highly satisfied with living standards, there seemed to be no clear division between community facilities and private houses. A systematic and detailed space planning technique was required. In addition, various community facilities are required due to the expansion of the community.

The purpose of this study was to analyze middle school students' consumption lifestyle and develop a program for measuring Ecological Footprint (EF) for them. For this study, 200 male and female middle school students in large cities, medium & small cities were selected to analyze their consumption lifestyle. It was also that the existing programs for measuring EF were studied and basic rules of setting up new EF indicators were established based on the results of survey and literature study. 15 indexes was selected by dividing the life areas into food, housing, traffic, goods and services areas and than the delpi computer programming tools was used to develop program for measuring EF in this study. The program for measuring EF can be used as educational materials for consumers' environment education in the areas of social environment education and school environment education. The followings are suggestions coming out of this study. First, it is required to revise and complement program for measuring EF analyzing the problems that occur when applying it to middle school students actually. Second, some data that used during normalization of EF ate originally from the USA. So it is necessary to change the data to meet the Korean situation. Third, it is necessary to have design work that can invite interests of students with consumers' environmental education materials through cooperation between environmental education experts and computer programmers. Fourth, it is necessary to have practical research with consumers' environmental education adding educational contents into EF measurement program. Fifth, it is necessary to develop a method for distribution an expansion of the program for measuring EF to make it usable in different types of environmental education materials.

We have focused on the roof construction method of Urban Hanok in Bukchon, Seoul. The Urban Hanok, urban traditional housing type, had been evolved In modern context from 1930's to 1960's. We have confused Urban Hanok with traditional Hanok, because they have similar figures. But Urban Hanok have the characteristics as a result of the roof construction method. The purpose of this paper is to define Urban Hanok more concretely, thus we payed attention to the roof structure, specially to the comer that each roof structure meets. So we got some characteristics of the roof construction method of Urban Hanok in Bukchon. First, the roof construction methods of the roof are transformed at the corner parts, where three purlin structure and five purlin structure meet. The collision of the different roof structure has made a lot of types. Second, the roof slope of Urban Hanok is more gentle than traditional Hanok, that is caused by ornamental double eaves and awnings. Finally these characteristics are results of the compact lot size in urban neighborhood. The construction method is a inclusive word that contain materials, composition, ornament and social common sense. With the understanding on the roof construction method of Urban Hanok, we can define the identity and the value of Urban Hanok, And we can suggest the policy and the design guidelines for the reservation and rehabilitation for Urban Hanok of Bukchon, Seoul.

In residential spaces, sanitary zones are where the most basic needs of human beings are met and are used by all members of the family. A high level of privacy is therefore required in their use. This research studies the current state of sanitary zones in collective houses and in detached houses from a comparative perspective first, and then analyses the satisfaction and dissatisfaction requirement levels of dwellers of each house in comparison so as to provide data to formulate a new design for sanitary zones that is suitable for each dwelling house. The results of this research are as follows. (1) The questionnaire respondents were mostly in their 30s and 40s (99.1% in total), and lived in a nuclear family system (87.7%). (2) The number of sanitary zones was found to be more than 2 in 62% of collective houses and in 60.7% of detached houses, which leads us to conclude that non-dwelling spaces are increasing in both types of houses. (3) Of the housing facilities,13% of collective houses and 9% of detached houses were equipped with a bidet. Both percentages are very low but it needs to be noted that the percentage is relatively high in collective houses. In safety facilities, the ratio of houses furnished with safety handlers for the aged was very low in both types of houses. (4) The residents of collective houses showed high levels of dissatisfaction with regard to the problems of storage space and steam production, while residents of detached houses expressed high levels of dissatisfaction with regard to the heating system, colors of finishing materials, size, dampness, steam production, and storage space.

We developed an education program for parents of adolescents titled Parents from Mars getting through to children from Venus. The program consists of five two-hour sessions each with a different theme; (1) parent-child communication, (2) study activities, (3) computer use, (4) children's daily expenses, and (5) children's daily-life plan. The program was test-run with seventeen participants, which included mothers of 4th grade(elementary school) to 9th grade (middle school) children. Based on data analysis, we found that average satisfaction level was 3.80 out of 5.00 and average goal accomplishment level was 3.91 out of 5.00. Most of the participants agreed that the program helped them to understand their children's problems, to look back on themselves as parents, to plan ahead, and eventually to improve their relationship with their children. However, it was also pointed out that the program needed to put more emphasis on practical lessons rather than theoretical lectures. For example, the need for more audiovisual materials, and more practical training during each session was highlighted by participants.
