Air pollution has a major health impact on people living in UB (Ulaanbaatar) city. The excessive high particulate matter concentrations, especially in winter and in the ger areas, lead to serious illnesses and deaths. In order to get information to improve air quality in UB city, we investigate the current situation of location of ger areas and emission data of ger stoves and three thermal power plants. We reported the burning experimental result of the ger stoves and the present situation of the health hazard in a previous report. Now, in this report, we calculate the several diffusion simulations of air pollution in 2010. Our study has been carried out in collaboration with our Mongolian partner"s TCDC (Tolgoit community development center, Songinokhairkhan district), and we want to make a contribution towards a cleaner and greener UB city.

Aim The objective of this study was to analyze the oral health among Japanese adults, with and without diabetes mellitus. Methodology The subjects were 518 community residents aged 20 to 91 years in Japan, who participated in the ＂Akita health and nutrition survey＂ and the ＂Akita dental disease survey＂, conducted in 2006. The surveys comprised a self-administered questionnaire, along with medical and dental examinations. Results Using the community periodontal index （CPI）, the mean numbers of sextants presenting codes 0, 1 and 2 were significantly lower in diabetics than non-diabetics among the 59 years or younger age group. Although the mean numbers of sextants with codes 0, 1 and 2 among the 60 to 69 years age group were lower, and sextants with a code X among the 59 years or younger age group were higher in diabetics than non-diabetics, no statistically significant differences were detected. The tendency of lower mean numbers of natural teeth and functional tooth units in diabetics than non-diabetics was observed, however no differences were statistically significant. Conclusion The outcome of periodontal disease seemed to be influenced by the diabetic state to some degree, but a clear association between diabetes and oral health status was not found.

On the outskirts of the metropolitan areas in Japan, the rapid development of urban areas and the improvement in transportation networks have brought various land use problems in their wake, including urban diffusion and the phenomenon of urban sprawl. There is a strong need for accurate predictions of land-use change and future urbanization, as well as investigation of the appropriateness of present land use controls and the land use controls that will be required in the future. This study took as its object the outskirts of the Keihanshin (Kyoto-Osaka-Kobe) Metropolitan Area, the second largest conurbation in Japan after the Tokyo Metropolitan Area, and used the digital maps and spatial analysis offered by GIS. It aimed to: 1) describe the characteristics of land use controls, land use and urbanization;2) develop an urbanization prediction model that considers the neighboring relationship of neighboring areas on a 100 m mesh unit;3) apply this model to the study area and verify its validity regarding the conditions of present land use;4) compare urbanization prediction results by this model with the present land use controls;and 5) make predictions for future urbanization and propose remedial measures for future land use controls.

This study aims to clarify the characteristics of volunteer activities in times of disaster, while taking into account the influence of the orientation towards information intensity, which is an important feature of contemporary Japanese society, and focusing on the volunteer activities for recovery and reconstruction in the disaster-stricken areas of the Great East Japan Earthquake. In modern Japanese society, because volunteer activities are being conducted in a variety of forms, those who wish to volunteer can participate in volunteer activities that suit their own situation. Further, in a highly information-oriented society such as modern Japan, many kinds of information systems can be used to conduct a variety of volunteer activities. Also, know-how concerning the introduction and methods of volunteer activity and recruitment for participants in volunteer activities are introduced using various information media, and there are many volunteer activities to choose from. Therefore, it is possible that through the diversification of volunteer activities, many people become involved in volunteer activities on a long-term basis, using ways of doing so that are possible for themselves.

This paper aimed to make proposals for disaster prevention and reduction measures based on the experiences and lessons gained through the Kumamoto earthquake. This paper firstly introduced disaster countermeasures of affected local governments within Kumamoto Prefecture. Next, by narrowing the focus on measures concerning the intangible side of things, this paper discussed three points including （1） issues concerning the assumption of disaster countermeasures; （2） issues concerning the BCP （Business Continuity Plan） of both government and private corporations, the DCP （District Continuity Plan） concerning local communities, the CCP （Community Continuity Plan） concerning local communities, and （3） issues conceming disaster countermeasures besides the two issues mentioned above. Based on the discussion results, it was pointed out that the disaster countermeasures assuming complex continuous disasters should be considered.

Psychiatric day care plays an important role as transitional support after discharge in Japan. However, interruption rate of the day care treatment is high during the introductory period. The purpose of this study was to clarify the experiences of psychiatric day-care patients during the introductory period and find an approach to care. A qualitative study with thirteen patients at the introductory period was designed to explore participant’s experiences through semi-structured interviews. At first, patients were confused about their attitude because they paid attention to themselves, and consequently closed their involvement with others. However, through therapeutic day care activities, they attempted to adapt themselves and gradually turned their attention toward others and accumulated interpersonal experiences. As interactions with others became more frequent, they became conscious of themselves and others. Finally, while having worries about the future, they looked toward recovery and became aware that they were changing. Experiences of patients during the introductory period were essential to their recovery and gave meaning to their day care usage. Nurses should collaborate with patients to determine whether day care would serve to open a patient’s life to new possibilities.

It has also become possible for people to easily acquire tourism information that matches their own particular tastes using the internet, so tourism has taken a more diverse range of forms. One of these is “content tourism” that became popular in recent Japan. Sgains such a backdrop, the present study aimed to design, develop, operate and evaluate a system that integrated three subsidiary systems including Web-geographic information systems (GIS), a tourism information system and social networking service (SNS) in order to support walking-based content tourism. This made it possible to create sightseeing routes and to submit, store, and view tourist attraction information. Additionally, the system was operated for one month in Chofu City, Tokyo Metropolis, and the total number of users was 42. During the operation period, 12 new sightseeing routes were created and 30 new tourist attractions were submitted. Based on the results of the web questionnaire survey, users highly evaluated the key functions of the system and the overall system. However, of those key functions, evaluations were somewhat low for the ease of operation of the creation function of sightseeing route, so the improvements must be made. From the results of the access log analysis of users’ log data, the total number of sessions in this system was 134, 64% used PCs, 36% used mobile devices, Therefore, the approach of designing the system such that the same functions could be used regardless of the type of device one is using was an effective design approach.
