For the problems in executing rural development, recent recognitions are that discovery, preservation, and utilization of area-unique resource are unsatisfactory, that participation of local residents was neglected, and that approach to gradual refurbishment of houses and common space of town in consideration of existing spatial pattern of the town was not adequate. Especially, neglect for exact investigation, analysis and evaluation on rural local resources is bringing about social problems such as mass production of uniform rural area and loss of local identity. In this study, rural resources were listed and resource evaluation items was designed in order to establish development direction of rural village. According to these results, for the efficient and reasonable drive of the resource evaluation system, following items are required; A premise of local development by participation of local people, Development of diversely appliable resource evaluation clauses, Establishment of development type in connection with resource evaluation clauses, Systematic management of local resource through spreading DB resource. This research was loused on unearthing direction development of rural village and theme. However, what should be reconsidered through continuous study is that resource evaluation clauses are somewhat general and not concretely illustrated. Therefore establishment of characterized development is expected through clarifying local identity and presenting direction of local development, with the importance of resource and systematic analysis in planning on rural village in the future.

Advances in sensor technologies have led to the instrumentation of sensor networks for bridge monitoring and management. For a dense sensor network, enormous amount of sensor data are collected. The data need to be managed, processed, and interpreted. Data management issues are of prime importance for a bridge management system. This paper describes a data management infrastructure for bridge monitoring applications. Specifically, NoSQL database systems such as MongoDB and Apache Cassandra are employed to handle time-series data as well the unstructured bridge information model data. Standard XML-based modeling languages such as OpenBrIM and SensorML are adopted to manage semantically meaningful data and to support interoperability. Data interoperability and integration among different components of a bridge monitoring system that includes on-site computers, a central server, local computing platforms, and mobile devices are illustrated. The data management framework is demonstrated using the data collected from the wireless sensor network installed on the Telegraph Road Bridge, Monroe, MI.

Continuously expanding information technology is changing the world in which our students live. Many schools are using this new technology and many schools are contemplating the use of this new technology. The ways in which teachers and students work, and their dependence on information technology, have evolved significantly-increasing the importance of getting the information technology infrastructure right in schools. Yet, all too often, most of schools are unable to take full advantage of the opportunities that information technology offers since those designing and fitting out school buildings have failed to consider information technology adequately. This study is to guide the physical design of practical networked schools. In this paper, we present the ways to achieve architectural solutions to the manifold problems associated with accommodation of information technology in schools. The practical guidelines for planning and managing information technology infrastructure-that is, the spaces and services provided in the school building to support the user' information technology requirements-are offered. Adherence to these guidelines will provide a substantial degree of adapability and flexibility in school buildings.

With the recent change of healthcare environment including rapid technological development, evidences are more and more important and necessary to support relevant policies in health technology assessment to provide safe and effective health services, utilizing medical resources efficiently. Despite of the emphasis on the importance of real world data and real world evidence in health care research, current infrastructure supporting clinical research is considerably weak due to absence of legal and institutional basis. However, in accordance with the Article 26 of the Health and Medical Technology Promotion Act, there is a limited legal apparatus that can be used only in public data with other dataset for the purpose of healthcare technology assessment at the National Evidence-based Collaborating Agency. Although the use of linked data from various sources was often required in the field of clinical research, it was not yet working well due to insufficient environmental conditions. In order to support the decision-making of medical practice and health care policies, data-linking platform for clinical research is needed. If the legal system that can link up to the data of the private institutions without violating the significant value such as the protection of private informations is established, it will be a decisive foundation reinforcing the researches and policy making processes for the improvement of the national health care system.
