More than eighty thousands of wooden printing blocks of the Tripitaka Koreans are accommodated in the Changkyeonggak which consists of two open structured wooden buildings, Peoppojeon and Sudarajang. These blocks are virtually in pristine state even after three quarters of a millennium. The excellent preservation could be attributed to the careful preparation and meticulous finish of the blocks. But the meteorological environment or microclimate should be one of the key factors for the preservation. To keep the blocks intact as it is or at least do not accelerate the deterioration, we should study the blocks and its microclimatic environment supplied by the Changgyeonggak and the topology of the site. As a Part of this effort we designed a computerized meteorological data acquisition system, which can handle up to 4,096 sensors. A partial but operative installation of 16 temperature/humidity sensors was set up in the Peoppojeon. We hope to have a chance to install a full fledged system in the near future for the compilation of the fuller environmental data base.

In the case of relatively good ground and construction condition in the deep excavation for the construction of subway, railway, building etc., flexible earth retaining systems are often used in an economical point of view. It is generally known that the mechanism of behavior in the flexible earth retaining system is relatively more complicated than the rigid earth retaining system. Moreover in the case of long span strut supporting system the analysis of strut axial force change becomes more difficult when the differences of ground condition and excavation work progress on both sides of excavation section are added. When deeper excavation than the specification or installation delay of supporting system is done or change of ground condition is faced due to the construction conditions during construction process, lots of axial force can be induced in some struts and that can threaten the safety of construction. This paper introduces two examples of long span deep excavation where struts and rock bolts were used as a supporting system with flexible wall structure. And the sections of two examples are 50 meters apart in one construction site, they have almost similar design and construction conditions. The characteristics of ground deformation and strut axial force change were analysed, the similarity and difference between measurement results of tow examples were compared and investigated. The effort of this article aims to improve and develop the technique of design and construction in the coming projects having similar ground condition and supporting method.

In this study, we classified and analyzed the type and cause of resident conflicts and made a solution at side of resident through resident survey study for research subjects located at photovoltaic system will be installed or not. The factors of resident conflicts based on news media release from 2006 to 2018 were classified to four types such as economic, environmental, technological and procedural factors. According to the news analysis, the types and proportion of resident conflicts in the photovoltaic system projects showed 33% of economic factors, 32% of environmental factor, 21% of technological factor and 14% of procedural factor. This news analysis may suggest that it is very important residents to share the economic benefits as well as to ensure the fairness of the procedures for carrying out the project based on transparent information disclosure during the business promotion and profit distribution stages. We conducted the poll survey in the rural towns where photovoltaic system will be installed or not. The poll survey results showed that (i) there is quite difference in agreement rate and other recognition for sensitive matters such as profit distribution, environmental and technological factors whether photovoltaic system will be installed or not, (ii) the resident conflict regarding the photovoltaic system installation can reduce through direct involvement of residents process. To solve these resident conflicts, the local governments should mainly effort and consider the supporting technologies and consults to solve clearly resident conflicts. In addition, it has to advertise the safety of photovoltaic systems regarding electromagnetic wave which were within the range of scientifically harmless to the human body.

After World War II, Japan experienced a great political and social shift, which brought a concern of emerging public landscape in urban development. This paper analyses the management of the aesthetic intentions in urban design effort. We reviewed the development of various public installation of artworks concerning urban landscape aesthetics through its administrative process in chronological order. The monuments during the first decade marked a shift in emphasis from the militarism of the pre-war and wartime period to one of peace. However, some of the monuments and sculptures are not immune to controversy. This became an issue that could no be ignored by public officials whose responsibility was to place the sculptures while maintaining sensitivity to public opinion. As public administrators began to consider the possibility that sculptures may contribute to improving public amenities, the contextual concepts were basically ignored. Some of the programs in 1970s began to show more respect to the context, while other programs in this period expressed more interest in educational aspects of sculptures in the public spaces. Urban development projects also seek to introduce artworks integrated to their urban design concepts in 1990s. Generally, the administrators responsible for these programs were rarely trained in any relative field study other than public administration. Installing sculptures tended to be considered as part of public works projects on the level of urban planning and construction. The general public is basically removed from participating in the critical decisions that actually impact their lives in relation to the artworks. In conclusion, public art in japan has unique social and historic background both in its advantages and disadvantages. Issues pertaining to art in public spaces have evolved over the decades as the term "sculpture pollution" began to appear by the mid 1990s. most of the problems originated in either the lack of monumentality, contextual consideration, quality, or public participation. From another point of view, these programs played great roll in the development of modern Japanese sculpture and patronizing process, and the creation of new urban landscape with aesthetic value. In this sense, they must be considered as successful and noteworthy examples of cultural administration and urban design policy.
