The purpose of the study is to come up with counter plans to the spatial change caused by an aging society. To achieve the purpose of this study, research methods are conducted in the literature survey and the census data are compared. This study focuses on an aging society, the current status of space and related problems, based on political economic spatial concepts, and then presents five countermeasures as follows. First, the planning considering the aging populations. Second, increase in total fertility rate and increase population absorption. Third, increased economic vitality of the elderly due to increased participation in the production of senior citizens. Forth, establishment and implementation of regional development plan for the elderly. Fifth, needs to transform the spatial policies of the aged to prepare a large gap in space. The result of this paper proposes the need to change the living space policies and planning to avoid mismatching between them, reducing the aging speed simultaneously. The study is expected to contribute to the establishment of a space plan for areas where the aging population is rapidly increasing.

In this paper, spatially-adaptive denormalization (SPADE) based U-Net is proposed to detect changes by using high-resolution satellite images. The proposed network is to preserve spatial information using SPADE. Change detection methods using high-resolution satellite images can be used to resolve various urban problems such as city planning and forecasting. For using pixel-based change detection, which is a conventional method such as Iteratively Reweighted-Multivariate Alteration Detection (IR-MAD), unchanged areas will be detected as changing areas because changes in pixels are sensitive to the state of the environment such as seasonal changes between images. Therefore, in this paper, to precisely detect the changes of the objects that consist of the city in time-series satellite images, the semantic spatial objects that consist of the city are defined, extracted through deep learning based image segmentation, and then analyzed the changes between areas to carry out change detection. The semantic objects for analyzing changes were defined as six classes: building, road, farmland, vinyl house, forest area, and waterside area. Each network model learned with KOMPSAT-3A satellite images performs a change detection for the time-series KOMPSAT-3 satellite images. For objective assessments for change detection, we use F1-score, kappa. We found that the proposed method gives a better performance compared to U-Net and UNet++ by achieving an average F1-score of 0.77, kappa of 77.29.

Urban Data collected through Sensor Network is becoming crucial to understand and analyse a city. Thus, the Ubiquitous Sensor Network builds the foundation of the u-City development. This research aims to develop an energy monitoring application with an intuitive visualization environment which integrates energy usage information on top of urban geospatial information. Such a system will be able to facilitate effective energy supply plan at the early stages of urban planning, and eventually to encourage citizens to conserve energy by giving them real time monitoring information in an easy to understand visual environment. The system provides multiple layers of energy-related information coupled with the geospatial information layer in order to accommodate multiple viewpoints. On the other hand, the system provides logical Level of Detail control based on urban spatial information hierarchy. We defined the system concept and functions, and designed the data structure and the methods of information visualization. This paper presents the visualization methods, data structure, interactions scenarios which combines spacial information, E-GIS data and the energy related sensor data. Furthermore this research tries to introduce the concept of Social Sensor Networking to enhance the monitoring quality.

The recent emergence of the paradigm of new urban planning for building intelligent urban spaces, such as U-City and U-Eco City, of which the concept of ubiquitous technology is applied, requires high quality three-dimensional spatial information of the urban area. The aim of this study is to build a multi-dimensional spatio-visual information system that includes the solution for visualization, spatial information search, analysis, and evaluation by integrating various types of 3D-modeled spatial information concerning the large urban-size area based on the latest GIS application technology. The range of this study is the integration, visualization, and utilization of spatial information with the goal of building 3D virtual urban environment of high-quality and high-resolution by increasing the utilization of the systematic urban facilities in order to fully reflect the actual user's needs, using the aerial LiDAR data as the plan to overcome the limitations of the existing 3D urban modeling. By reproducing the virtual urban environment the most similar to the actual world through the mash-up of satellite images and aerial photos on the standard format of spatial information constituted of properties and signs, the system will be built with many analysis and utilization functions that support the view and sunlight analysis, various administrative tasks, as well as the decision making process of the city.

Over the past years, complex project which has the object to accomplish housing complex, commercial complex etc, recently is changing to multi-complex projects because of development in IT sector. Improvement in the quality of life, life pattern has been and is being changed, these modernized and improved version of life brings the concept of U-city. Department of urban planning and engineering, civil engineering and architecture engineering in every university educate students according to the changing world in order to handle these complex projects in real world. In most cases department of urban planning and engineering teach project planning and department of civil and architecture engineering teach project design and construction. In most of the projects planning followed by design and construction need to be accomplished, but current observation in the present curriculum shows that it is difficult to expect the continuity. The present curriculum of civil engineering has to change as complex projects deal with various different structures during the design and construction phase of these projects. This study examined curriculums from the department of urban and civil engineering related to structural design and construction and survey importance of design works which overlap urban and civil engineering targeted on design engineers. After understanding design works and results obtained from survey we propose for an advanced efficiency method.

This study assessed 1) the coverage of the entry-level responsibilities and competencies for certified health education specialists (CHES) developed in the United States (U.S.) by 140 current health education-related professional preparation programs in Japan, and 2) barriers and concerns related to the development of Japanese health educators. A cross-sectional survey study was conducted to Japanese professors teaching health education-related courses at 4-year universities/colleges in Japan. All entry-level CHES responsibilities and competencies were generally covered to different degrees by the study respondents. The top 3 responsibilities most emphasized by the respondents were Responsibilities I, related to need assessment skills, Responsibility II, related to planning health education programs, and Responsibility III, related to implement health education programs. The 3 competencies most frequently covered by the respondents were related to needs assessment skills (Competencies 1-3). The competencies least covered by the respondents were those related to Responsibilities V (Competencies 1619). Other competencies related to role modeling, cultural competencies, and planning youth health education programs, were recommended. In addition, the major concerns and opinions that the respondents reported for this topic pertained to 1) Professional training, 2) The need for well-defined professional roles, and 3) The importance of licensing. The results suggested that Japanese health education-related programs cover all CHES responsibilities and competencies developed in the U.S. to different degrees. However, they tend to focus more on needs assessment, planning and implementing health education programs. Although possible responsibilities for future Japanese health educators were recommended, further research to identify the most appropriate responsibilities and competencies for this profession is needed. Major barriers, concerns and opinions reported by the respondents should be discussed at future meetings for this profession.

Smart City is urban development for complex problem solving that provides convenience and safety for citizens, and it is a blueprint for future cities. In 2008, the Korean government defined the construction, management, and government support of U-Cities in the legislation, Act on the Construction, Etc. of Ubiquitous Cities (Ubiquitous City Act), which included definitions of terms used in the act. In addition, the Minister of Land, Infrastructure and Transport has established a "ubiquitous city master plan" considering this legislation. The concept of U-Cities is complex, due to the mix of informatization and urban planning. Because of this complexity, the foundation of relevant regulations is inadequate, which is impeding the establishment and implementation of practical plans. Smart City intelligent service facilities are not easy to define and classify, because technology is rapidly changing and includes various devices for gathering and expressing information. The purpose of this study is to complement the legal definition of the intelligent service facility, which is necessary for integrated management and operation. The related laws and regulations on U-City were analyzed using text-mining techniques to identify insufficient legal definitions of intelligent service facilities. Using data gathered from interviews with officials responsible for constructing U-Cities, this study identified problems generated by implementing intelligent service facilities at the field level. This strategy should contribute to improved efficiency management, the foundation for building integrated utilization between departments. Efficiencies include providing a clear concept for establishing five-year renewable plans for U-Cities.

The purpose of this study is to understand a architectural characteristics of local church in Virginia, U. S. This study focuses on not only analyzing the worship and service program inherent in the site planning of local church but also introducing worship service space and chancel elements of it in the village of garden area. We surveyed five protestant churches where are located in suburban and rural area outside of Midlothian city in the early August, 2010. I surveyed church building site and worship service space of churches focused on platform design, interviewed the historical background and program of churches with ministers, and corrected annual calender and newsletter. The results of this study are as follows. First, the characteristics of site plan have a comfortable parking lots and site of churchyard(cemetery) with playground that can take an activities out of chapel. The axis of church building follows to front street. Second, worship services keep two types of traditional and comtemporary worship in order to consider of both adult and youth members. The worship hall has a balance of bilateral symmetry. Third, the form of platform is built that is able to perform a music drama and movement of sermon without only one church, GraceLand Church that church building has over fifty years, and they stick to simple traditional type of Chancel that is established by pulpit, table(altar), baptistery(only baptist church), music instruments, and so on.
