The purpose of this study is to search for a rationale of world geography curriculum. Elementary school children tend to get impressionistic and distorted information about other countries through snapshot TV programs. But they need to get more balanced understanding about them from the perspective of each country. Children's judgment about other countries, favorable or unfavorable, tends to be emotional, based on the first-order conditions of life in those regions, such as atmosphere, food, and habitat, and the symbolics of the place. But their systematic understanding about the relationship between their own life and the life of other locations or countries tends to be meager. It seems to be partly due to the practice of co-centric curricular construction. The geography curriculum may have to be in relation to other countries, from the regional geography of the third grade on.

Since 1997, Dr. Shin-ya Nishimura has been developing an actual town planning project named the "Gangi Project". Students, inhabitants and local professionals walk around Omotemachi, examine the characteristics of the environment and the inhabitants' way of life, discuss plans and designs for traditional wooden arcades called locally "gangi". Students and inhabitants build the gangi together every year. The purpose of this study is to clarify how an experimental project aiming to preserve a living environment obtains sustainability as an actual town planning exercise. The research hypothesizes that sustainable town planning should include strategies for financial autonomy, active participation of inhabitants, supports from local professionals, an acceptance of changing environments, and responsible construction. The project has been carried out as a part of actual town planning, and continues to create a daily living environment based on the recent economical and industrial situation of the town. By focusing on the influences of the project on the town and inhabitants, the study has revealed the possibility of an actual town planning with small budget, and importance of a collaborative relationship with various participants in order to foster a sense of responsibility regarding the construction. The project also highlights the implication that sustainable town planning creates not only a participatory system but also a collaborative one in which participants take responsibility for the issues involved in the construction process.

College students living in university dormitory continuously experience unique physical and social living conditions, being away from their hometown and loving families. Most college students has engaged in a very limited social activities in dormitory area. Studies have shown that sense of community(SOC) is closely related to students' social activities. However, few research have examined the relationship between physical environment and sense of community. Therefore, this research aims to evaluate the effects of physical environment of dormitory on students' perceived sense of community and their social interaction. Extensive literature review found that developing social interaction and building a sense of student community improve students' overall residential satisfaction with dormitory and personal academic growth. Survey on A university dormitory and Chi square analysis (${\chi}^2$) indicated that each group's individual characteristics such as gender, grade, living period, and personality were statistically significant on the level of SOC at the level of p=.01. Individual analysis of SOC showed that sense of belonging was higher than shared emotional connection, which means certain level of intervention is needed. Pearson correlation analysis validated that there exists statistically significant relationship between physical environment and SOC. Further it also found that the most important predictor in facilitating social interaction were comfortable, quiet, and enough social space around the dormitory.
