This paper identifies residential preference of child-rearing households based on questionnaire and interview survey. The results of this paper are as follows : 1) Child-rearing households tend to move in the same area, and in area well-known; 2) Single parent households tend to value the education environment and local community; 3) Working single parent households tend to value the proximity of housing, a school and a workplace to improve efficiency of commuting and taking their children to school; 4) Child-rearing households with children aged 0to2, 3to5, and schoolchildren tend to value housing performance, educational environment, and children’s school and friendship, respect.

The purpose of our study was to investigate radiation dose for lower tube voltage CT using automatic exposure control (AEC). An acrylic body phantom was used, and volume CT dose indices (CTDIvol) for tube voltages of 80, 100, 120, and 135 kV were investigated with combination of AEC. Average absorbed dose in the abdomen for 100 and 120 kV were also measured using thermoluminescence dosimeters. In addition, we examined noise characteristics under the same absorbed doses. As a result, the exposure dose was not decreased even when the tube voltage was lowered, and the organ absorbed dose value became approximately 30% high. And the noise was increased under the radiographic condition to be an equal absorbed dose. Therefore, radiation dose increases when AEC is used for lower tube voltage CT under the same standard deviation (SD) setting with 120 kV, and the optimization of SD setting is crucial.

This paper analyzed how Jizo-Bon, small-scale religious festivals held widely in Kyoto, contributes for improving resilience of “cho”, the basic communities in the central urban area of Kyoto. We clarified that inhabitants who has no involvement or quite limited involvement to “cho-nai-kai”, community management associations are joining management of Jizo-Bon. The result means Jizo-Bon is an opportunity for inhabitants to be involved in “cho” except for “cho-nai-kai”. In addition, it means Jizo-Bon provide “cho” with “redundancy”, another key factor of resilient communities in addition to “diversity”. We also clarified that it is caused with characteristics of Jizo-Bon described as follows. 1. Distribution of management loads to various inhabitants Loads for management of Jizo-Bon are distributed to the extent that each inhabitant can bear them. For example, people can join in the management only with "arranging place", "supporting events on the day" which is easier to bear than other roles as "manager of Jizoubon", "preparing for events" etc. It is also clarified that inhabitants who are usually difficult to be involved in communities as those who are not belong to "cho-nai-kai", those who moved in "cho" recently, single old inhabitants and apartment inhabitants participate in Jizo-Bon. It means Jizo-Bon contribute to "Diversity" of "cho". It is expected that the people involved in Jizo-Bon management to make roles also in "cho-nai-kai" in the future. However, the people differentiate the former involvement from the later as far as we analyzed in this paper. That make it possible the people who cannot bear much loads of "cho-nai-kai" management to be involved in "cho". 2. Flexible meaning corresponded with community situation Meaning of Jizo-Bon is flexible corresponding with situation of communities and people can join in it with their own purpose or motivation. The recognition about Jizo-Bon is different in the two "cho" communities selected as survey area in this paper. Inhabitants in "A cho", a community managed mainly by people who are living there for long term, recognize Jizo-Bon as "religious events" and "traditional events". On the other hand, inhabitants in "B cho", a community including people who moved in "cho" recently, don't recognize as "A cho" and accept it as rather for "communication among inhabitants" and "fan of inhabitants". It means that Jizo-Bon is sustaining by adding or changing meaning of itself corresponding with characters of community as its population structure. In addition, we also clarified that Jizo-Bon is an opportunity for people who moved inside the city to become familiar with their new community because Jizo-Bon is held widely in the urban area of Kyoto. The image of Jizo-Bon shared among citizens seems to be a key factor making it possible for various inhabitant to join and collaboratory manage it. Jizo-Bon is a resource which provide various inhabitants with opportunity to involve in communities depending on their situation and interest. It is precious especially in the context in which decrease of interest and lack of manpower for community management is serious problem. On the other hand, once Jizo-Bon is lost, it is difficult to restore because the characteristics of Jizo-Bon we clarified in this paper is acquired through long-term experience. It is necessary to advocate and measure for conserving Jizo-Bon for the future.

&nbsp;In the current Japanese urban areas, bonds of local residents have been dilutive, under the influence of low birthrate, aging, personalization of life, and diversification of values. After Great Hanshin-Awaji Earthquake, these problems become obvious, and there has been a growing demand to regeneration of neighborhood community.<br>&nbsp;The purpose of this study is to explore the way of planning of open type dwelling unit to activate the community. This paper examines the relationship between the dwelling unit plan and the formation of territory on 3-dimensional streets in case of the experimental housing "NEXT21". Especially, focusing the "Visual connection" between a living room and a 3-dimensional street, we analyzed the spread of personal areas on 3-dimensional streets.<br>&nbsp;If there is a "Visual connection" between a living room and a 3-dimensional street, it caused the "intermediate space" with the device in the vicinity of the boundary. The device is the invitational design technique, also the exclusive design technique. Due to differences in the arrangement of the "intermediate space", they were classified into five types of "Visual connections" between a living room and a 3-dimensional street. To target the dwelling unit that has direct "Visual connection", we analyzed "Areas of comfortable" and "Areas to be worried about if there are strangers". "Areas of comfortable" are recognized as the private areas of proceeds. "Areas to be worried about if there are strangers" are recognized as the areas visible from the familiar life spaces.<br>&nbsp;If the living room of the dwelling unit is spread in the "intermediate space", "Areas to be worried about if there are strangers" are formed in the areas of "Visual connection" with not only the living room but also the "intermediate space". Furthermore, "Areas of comfortable" are formed in the areas of the invitational quality. However, "intermediate space" having a large opening prevents the formation of "Areas of comfortable" under the influence of the exclusive quality.<br>&nbsp;Through analysis, we were able to see how the private areas spread the living room to the "intermediate space" and 3-dimensional streets in stages. Simply not only to pursue the securing of privacy, but also it is necessary to perform open type dwelling planning in the hope that the community will be formed after a few years. There, it is important that "intermediate space"s become cores of communication, and connect in three dimensions by "Visual connections".
