This study examined the physiological and psychological effect of having plants at workplace everyday. Nowadays, it is getting increasingly important for people working in their urban office to relieve their severe stress. In Japan, it is mandatory to participate in 'Job Stress Questionnaire'. As one of the ways to reduce stress of employees, there has been exploration around putting greenery in the office. Hence, this survey tries to measure the effect on employees at workplace with and without plants by making a simulated office space. As a result, We found that the effects of plants don't decrease and increase if people see them everyday. In a simulated office space, people tend to like the room with plants and they feel more at ease and get more energetic. Additionally, in a simulated office space with average green visibility of 3 to 4%, it was found that the people's pulse was getting slow. The above led to the conclusion that seeing plants everyday has a good influence for employees.

In Japan, the form of multifaceted use of agricultural land introduced into rural plan to revitalize the rural area is accepted, but there is no such an equivalent in China, and it has become a problem of the adjustment of "diversion" and "securing" agricultural land. The purpose of this research is to propose a spatial design plan aimed at solving the problem of adjustment of the farmland by picking up Huangqi village of Fushun City in China as a model research field. This research will go through the following flow: 1. Analyze the data from literature survey, hearing survey and field survey; 2. Examine the way of important bases; 3. Propose the spatial design plan of concrete images of target space. The features are as follows. 1) Using corn farmland, we created a space for the base that made other use possible while holding function of agriculture. 2) By designing the farmland stage in the corn farmland, where the farmers could take a break, and the visitors can experience agriculture, it also contributes to the improvement of communication between people from urban area and rural area. 3) It draws out the charm of agricultural land by utilizing existing resources and forming agricultural landscape experience base.

In recent years, it has become important for parents and their children to experience nature. However, the program currently held at the park requires preparation and knowledge. Therefore, easily experiencing its contents when the program is not being conducted is not possible. Hence, we created a nature play guidebook at the Kabutoyama Forest Park to make nature play easy for parents and children. We referred two "Waldkindergarten" active in this park, involving nature play on a daily basis. After investigating the nature play here, we found five characteristics: "playing as a tool to play the nature, "play with discovery," play in sensation, "play with adventure," and "play with making." We made a guidebook off ering the following: (1) suggestions for the kind of play that can be played at each point, (2) play that does not need preparation or knowledge, (3) showing how parents should be involved with their children during play.

Senecio madagascariensis Poir. (fireweed) is a toxic African plant which has spread rapidly along Osaka Bay, especially in Awaji Island, western Japan. Field survey was conducted in order to clarify the distribution pattern and possibility of distribution control of this invasive alien species in Awaji Island. The fireweed communities were frequently and continuously distributed at the southern part of the Island. At the northern part their distribution was restricted and discontinuous, but the distribution has been expanding. Large and dense covers of fireweed communities established on newly constructed or recovered artificial slopes along roads and dam sites. Sparse covers of the communities were found on bars of a river and wet and steep slopes of a small fall. Abandoned paddy fields near from dam sites were also covered by fireweed. While the distribution of the species was restricted to open site, the habitat of the species ranges from dry to wet site from the view point of soil condition.
