The purpose of this paper is to research of measures of environment for children in the house development in Tokyo. A population increase by the house development as a factor, a child care facilities be insufficient. In the ordinances and the guidelines of the house development, there is local government that demands the construction of child care facilities as developer's obligation. Child care facilities are constructed with the apartment house in the local government that demands consideration to neighboring areas. But in the local government that demands the infrastructure, it tends not to be actually constructed though there are regulations. The house development plays the role of the arrangement of environment for the child care, and the arrangement of the day nursery is effective for waiting-list child. It is necessary to consider about child care facilities planning for environment for child care.

In this paper, the current state of facilities where the kindergarten and the child care place have been managed by the questionnaire survey in a nationwide scale as one body is understood. The management situation selected fi ve different facilities based on the result of this analysis in addition, the spot observation investigation was done, and an actual management situation of Integrated Facilities within Functions of Nursery School and Day Nursery was shown. It was able to be pointed out above that the feature of the problem and the all-in-one design facilities because of the united management of the kindergarten and the child care place was the one by "Child for a short time and the child's for a long time coexistence" and "Child for a short term and the child's for a long term coexistence" from two investigation results. Then, Chapter 3 and Chapter 4 paid attention to kindergartener's difference at the facilities stay time and length-of-stay, clarifi ed the development of the activity scene by the change of the number of kindergarteners during a day, and considered kindergartener's acaptive process.

Recently, there has been a great demand for day nursery in Japan. The floor space per person, which is provided in minimum standards for child welfare facility, has not been revised for 60 years though this is the only criterion for the environmental level in day nursery. The purpose of this study is to consider whether it is relevant to use the floor space of eating and napping per person, for the means to reconsider the floor space per person which is not said to be well-founded scientifically. We observed four-year-old-children in detail while they were eating and napping. We also measured each space of nursery rooms. 4 nurseries fulfilling the following criteria were selected; eat and nap in the same room,20-30 children for each class, 2.0m2 per person in nursery room. As a result, we found that eating and napping space is 0.80-1.65m2 and 1.22-1.44m2 per person, respectively. Therefore, we figured that the necessary space of eating was 1.03m2 per person and of napping was 1.40m2 per person, respectively(2.43m2 per person in total)in order to make comfortable nursery room. To conclude, the eating and napping floor space may become one of the effective index to develop the nursery environment hereafter.

This paper's aim is to grasp implications to situate play areas in nursery school and day nursery. After observational investigation on basic distribution of children thorough a day, the following points emerged: 1) Class activities are distributed in the open area mainly in the middle of the room; 2) Long term daily life routines tended to subjugate the short term ones as a distribution tendency; 3) Each age group showed different tendency in the distribution of free activities. As focusing on how children's activities expanded, the size changing behaviors were categorized with the changeability of area size and group size.

The purpose of this paper is as follows: (1) to obtain knowledge on current management of integrated facilities within functions of nursery school and day nursery (hereinafter, Integrated Facilities), based on questionnaire resurvey, (2) to analyze the relationships between management conditions such as integration type and scale, and the mixture of children of short- and long-hour daycare, and (3) to analyze the activity place changes during a day at facilities of the mixture of children of short- and long-hour daycare, based on a hearing survey.The results are as follows: (1) reasons of integration strongly influence on facilities management, (2) scale of facilities is related to reasons of integration, management type and building configuration, (3) characteristics of Integrated Facilities are demonstrated by the ratio of prescribed number of children to the maximum capacity, which is equivalent to the ratio of area used for daycare functions to the whole, (4) the elements such as fluctuation size of children number during extended daycare time, presence of dedicated room for extended daycare, and total number of classrooms, influence on the frequency of activity place changes, and (5) The area used for extended daycare is decided according to the convenience of watch, staff number, appropriateness for activities and so on.
