<p>Why "street smoking" is so controversial in cities, Tokyo? Residents have been suffered from butts of cigarette and danger of burn. Considering these situations, all cities in Tokyo have introduced code which restricts street smoking. However, the detailed contents of the code vary according to the condition of each city. Chiyoda City is the first city which fine smoking on the street, not only while walking but also while standing or sitting. On the other hand, the city has been subsidizing private sectors to set smoking spaces inside building and so on. This case study, we overlooked the codes for clean community then discussed the issues on current situation regarding street smoking and possibilities for coexistence among the various senses of value in public space in cities.</p>

This paper presents an optimization method of the joint arrangement for shell structures composed of CLT panels. The joining system is modeled as link elements with multidirectional stiffness. Their stiffnesses are calculated by multiplying the weight parameters defined as the design variables to the original stiffnesses. Furthermore, the joint arrangement is controlled by multiplying a power-law function to design variables. An optimization problem is formulated to minimize the strain energy. The effectiveness of the proposed method is shown through numerical examples. It is confirmed that the joint arrangement in each direction is optimized corresponding to the stress state.

This study aimed to establish the spatial theory of psychiatric nursing bases that support patient recovery following a series of previous studies pursuing the uniqueness of the psychiatric healthcare environment as a “place for treatment.” The survey captured the characteristics of how patients with psychiatric disorders use space and the establishment of a shared space with psychiatric nurses. Furthermore, the professionalism of psychiatric nursing and the utilization of nursing bases for specialized psychiatric nursing were reevaluated through an understanding of how nursing behavior and the location of nursing bases affect where the patients choose to be.

This paper aims to clarify the characteristics of the Post-War reconstruction plans of the provincial towns, Makurazaki, Kushikino, Akune, Nishino-omote, Tarumizu and Kajiki in Kagoshima Prefecture, where planning and implementation were carried out collectively by the Prefectural Office of Kagoshima. This study comprehends the planning concepts described in "Plan Documents on the Land Re-adjustment" prepared for each towns, and investigates how the urban design in the reconstruction reflected them. Under the post-war circumstance, positive goals were set up particularly in the port towns like Kushikino and Tarumizu, where became the South End of Japanese territory since the islands in the south of the lat.30°N. were under U.S.Occupation. And by the distinctive design solutions, for example with the circus or water-front square, indivisualities of the townscape in each towns were realized.

The "floor" that is in constant contact with people is important for users to spend comfortably and safely in the architectural space. Improving floor performance (safety and comfort) is considered to be an important issue for all generations, including children, adults and the elderly. The purpose of this study is to be safe and comfortable for children and the elderly, and to solve the problem of floor impact sound. It is "Development of tatami with consideration for sound insulation performance and safety and formulation of design guidelines". In this paper, we first focused on tatami as a basic study. We examined heavy-weight floor impact sound, the hardness at the time of a fall collision, and the hardness at the time of walking. In addition to commercially available straw tatami and building material tatami, five types of tatami mats focusing on vibration isolation were prototyped and experimentally examined. For reference, we also examined light-weight floor impact sound. As a result of this paper, the following findings were obtained. 1) Straw tatami and building material tatami had no effect on the heavy-weight floor impact sound level reduction in the 63 Hz band, and were about 0 to -1 dB. In tatami mats that was prototyped in this paper, considering the vibration isolation, we were able to achieve a performance improvement of 3 dB by reducing the heavy-weight floor impact sound level in the 63 Hz band. 2) Regarding the hardness at the time of a fall collision, straw tatami and building material tatami were 50 to 53 G. The prototype tatami mats had a large impact mitigation effect of 20 to 31 G. 3) Of the prototype tatami mats that were able to realize (1) and (2), T4 and T5 were also good for walking. 4) Regarding the four types of performance related to floor hardness, the relationship of quantitative evaluation of each performance was clarified. It turns out that none of the performances correspond linearly. It was suggested that it is necessary to examine each layer in the floor cross section and the combination of each layer for each performance. As described above, in this paper, it was found that the prototype tatami mat does not impair the walking feeling, and the effect can be obtained by the amount of reduction in heavy-weight floor impact sound level and the hardness at the time of a fall collision. In addition, the effectiveness of introducing such a vibration-proof structure into tatami mats was suggested.

The purpose of this study is to analyze the effectiveness of Compact City policy which is adopted by many cities as the idea of sustainable city planning measurement. The results are as follows;<br>(1)Actuary in Aomori City tendency to become compact has appeared after 2000.<br>(2) But the people who tend to live in inner city and supports population increase in city center area are mainly young generation, and the aging of population in suburban area is still progressing.<br>(3) It is expected that elderly people who cannot move to inner city by economical difficulties will be left behind, so Aomori City Government needs to adopt more effective policy for accelerating removal to inner city of elderly people.

The response analysis was conducted considering the site amplification effect on Japanese conventional wooden houses in metropolitan area in this paper. Then, the general tendency of seismic response of the Japanese conventional wooden houses was investigated from the analytical results. Finally, the wooden houses damage estimation map in the metropolitan area was shown for a disaster prevention material. The major findings obtained in this paper were as follows. 1) If the base shear coefficient was 0.1, the first story's maximum drift angle exceeded the drift angle of 1/20, judged as collapse at all analytical sites in the metropolitan area. If the base shear coefficient was 0.4, response drift angles showed values below the safety drift angle (1/30(rad.)) judged as severe damage in most sites.2) Even if the base shear coefficient was 0.6, the maximum response drift angle was larger than the safety limit drift angles (1/30(rad.)) at some sites in Site class 2 and Site class 3.3) In the Site class 3, it might be possibly less than acceptable drift angle even for houses whose base shear coefficient is not so high, if the site acceleration response spectrum is small within the shorter period less than about 1 second.4) It was not easy for wooden houses to reduce their response at the sites in Site class 2, and the sites judged as Site class 3 closer to Site class 2. 5) The phenomenal above mentioned in items 1)~4) were possibly understood from the acceleration response spectrum considering the site amplification effect.6) From the damage estimation map presented in this paper, it may be understood that the maximum response drift angle was large near Tokyo Bay and Chiba's coast and that the sites where the maximum response drift angle was relatively small were the northern Kanto region, such as western Saitama, southern Ibaraki, Tochigi, and Gunma.

In Italy, the conservation and utilization of historical cities, landscapes and regions are conceptual values that have always coexisted with modern urban planning. With post-World War II reconstruction, urban planners began studying ways to conserve historical landscapes in agricultural regions. They established planning methods from a botanic perspective and human geography perspective. Since 2006, in their cultural landscape management plan, urban planners have connected the conservation of physical historical landscape to the recuperate of social and economic foundations of a region. In such way, they have completed a scheme that draws on the history of a region.

This research examined the relationship between renovation work done in common and exclusively-owned areas in condominiums as well as the planning of such projects, focusing on the following three issues. 1) Timing of renovation work in common and exclusively-owned areas and issues A survey of companies with experience in condominium renovation revealed there is a correlation between work in common areas and in exclusively-owned areas, such as works in the exclusively-owned area taking place on a certain scale before or after works in common area. Planning both works together in the plumbing renovation is assumed to have an advantage in reducing risks of water leakage in the whole building by renewing both pipes in the same cycle. 2) Integration of renovation work in common and exclusively-owned areas and issues In recent years, some large-scale renovation projects have integrated work done in common areas and exclusively-owned areas to obtain rationality and other benefits. Analysis of water supply and drainage facility renovation in which the work was done in common and exclusively-owned areas at the same time has confirmed that costs of the optional works in the exclusively-owned areas can be about the same as the common areas. Also, a case study on integrated water supply and drainage facilities work confirmed that the optional works were done on about half of the exclusively-owned residential units at the same time as work on the common areas, pointing to the importance of a system for building management association efforts and a mechanism for promoting it. 3) Rule compliance and effects of rule revision Recent years have also shown that work for renovation of exclusively-owned areas cannot be done because of accompanying work on common areas due to building management agreements and other constraints. We therefore surveyed condominium management companies to clarify the actual situation of management rules and sort out the issues related to renovation work on exclusively-owned areas. The results showed that the management rules for aging condominium buildings do not cover exclusively-owned area renovations and that the rules had not been amended, pointing to the need for detailed remodeling rules to be written or existing rules revised. Furthermore, a case study of condominiums that flexibly revise rules to meet the needs of all parties confirms that rule revisions promote exclusively-owned area renovation, pointing to the need for rules and flexible rule revision that ensure that exclusively-owned area renovation work proceeds smoothly.

In Japan, super high–rise condominiums have become highly in demand because they are generally convenient and have excellent views, large–scale open spaces, and common facilities. On the other hand, these condominiums have some issues such as dealing with disaster prevention, negative impacts for local area, and weakness of local communities. Therefore, it is necessary to grasp residents’ consciousness in order to solve issues in super high-rise condominium area. This study aims to grasp residents’ interaction in the local communities and their willingness to participate in local and community activities, and clarify the structure and factors of their willingness to solve local issues in super high-rise condominiums. We targeted in specific area of Kawasaki City. In this area, super high-rise condominiums have accumulated due to redevelopment such as factory sites since 2005. We conducted interview survey of each management association of super high-rise condominium and area management organization in this area, besides questionnaire survey of residents in two super high-rise condominiums in order to grasp actual condition of residents’ interaction and willingness to participate in local and community activities. Firstly, we grasped residents’ characteristics of interaction and their consciousness. Many residents’ relationships are formed by the interaction in their condominiums, except for the relationships related to children. Approximately 40% of residents hope relationships such as being able to help each other in the event of emergencies, and they have high consciousness of disaster prevention. However, there are a certain number of residents who hope general relationships such as closeness of their age. Secondly, according to the covariance structure analysis, the high willingness for regional contribution activities directly increases the degree of willingness to solve local issues, but neither the willingness for community activities nor the willingness for condominium’s contribution activities lead to the willingness to solve local issues directly. Finally, we analyzed factors of their willingness to solve local issues. The factors that motivate residents to solve local issues are having their clear purposes such as participation of disaster prevention activities and cultural activities such as hobbies, and the ability to solve local issues. In conclusion, residents in this area have highly motivation of disaster prevention and, their willingness for community activities does not directly lead to their willingness to solve local issues. In order to improve residents’ willingness to solve local issues in super high-rise condominiums, it is necessary to build the local organization which specializes to deal with issues and purposes.
