This paper aims to clarify changes of community neighborhood in the densely settled area of Korean in Japan through the comparative analyses of surveys in 1994 and 2006 of M district in Osaka City. Detailed characteristics of shop owners and their buildings in M district were clarified by the result of survey in 1994. We tried to identify the shop owners who had withdrawn from the district after 11 years and had newly come in the district to compare the shop name and the state of buildings. Findings are as follows. Most of owners who had already withdrawn from the district were Japanese owners. More Korean owners had opened new shops in the district. All demolished buildings were owned by Japanese owners, on the other hand, new shop buildings were built by Korean owners. These findings mean the withdrawal of Japanese owners is clearly recognized from the change of M district.

The objective of this study is to clarify the characteristics of the utterances and the dialogues of those who visit the monthly market on the pedestrian deck, in order to gaining feedbacks for how to create the spatial liveliness. The activities of the 176 visitors of the market held in the downtown of the Otsu, Shiga prefecture, were observed. The results are as follows. 1) 72 visitors talked to the merchants. 87 cases among such 222 utterances developed into the conversations. 2) Questions about merchandise tended to develop into the conversations. 3) The cases of the utterances and the dialogues increased when the visitors either stayed at the market place more than 10 minutes or walked around the whole place. 4) The visitors' actions to the goods and the merchants as well as the merchants' actions to the visitors were observed and thought to be the triggers of the utterances just after them. Finally, several problems and suggestions for increasing more opportunities of the conversations in the market place were considered.

In recent years, introduction of multimedia tools is growing to the planning field according to the wide spread of the Internet and the development of computer technology. Various education support systems have been developed and applied for professional education on the field of architectural planning and designing using CAD and WEB application. This paper introduces an on-line cooperative planning and design system and studies its educational application as an exercise tool for practicing public participation using the Internet Free Access. A system is developed for the public park planning and designing with the on-line system, and its possibilities for an educational tool are examined through an experiment. As a result of this study it is concluded that the system can be applicable for the educational usage although some revisions are needed.

Today, one of the most important problems related to disaster management is how to promote improvement of seismic performance of old housing. This paper presents the change of the number of housing and the density of housing in the 23 special wards of Tokyo from 1978 to 2003 with regards to structure and construction generation. In order to analyze the dataset, the housing is classified into 4 types (wooden housing built before 1980, wooden housing built after 1981, non-wooden housing built before 1980, and non-wooden housing built after 1981). Then, it clarifies how urban vulnerability in Tokyo from the viewpoint of housing seismic performance changed in the three decades after 1978.

Measure 37 of the Oregon State, which obliges governments to compensate landowners if their land value decreases because of land use regulations, was approved in 2004. Due to lack of financial resources, governments forgo regulations. Hence, the Oregon State faced the crisis of the growth management policy based on land use control. In 2007, the Oregon legislature passed a new law that revised the Measure 37 after public hearings and put it as a referendum, Measure 49, which passed with 61% of approval. Measure 49 admits the right of construction of 1-10 houses and transfer of the right of claim, while it denies large-scale development to protect agricultural land and forest. In this manner, Measure 37 was modified in a democratic and compromising manner.

Based on literature survey, we found the history and current status of a theory of Place Based Crime Prevention (PBCP), which is used as theoretical background of planning for crime prevention in UK and USA. From literatures that were published after 1960, the followings were identified. 1) PBCP which had been born in the 1960s faced four challenges by 1990s, which were the limit of the effect, the limit of the applicable space, the practical difficulty and the concerns about the side effect. 2) PBCP in the latter period born in the late 1990s has come to include the comprehensive concept, the expansion of the applicable space, the practicability and having the broader objective. 3) PBCP has being developed to share goals with the resent planning theories such as New urbanism and Urban village.

The purpose of this paper is to know the users' attitude to CCTVs in parking lots of an apartment complex in Chiba City and analyze it with SEM (structural equation modeling). The major findings were as follows; (1) They had great expectation for CCTVs and half of them felt their fear of crime decreased. (2) 92% of them approved CCTVs and it was only 5% who had concern about invasion of their privacy. (3) Their approval was made up of the expectation and the concern.
