Living infrastructure facilities are concentrated in cities with high population density, it is necessary to supply basic living infrastructure facilities to promote welfare in rural areas. The establishment of basic living infrastructure is the minimum right for daily living of local residents. It is supplied by considering national economic and social characteristics through national minimum standards, but it is limited to be practically applied to rural areas where many villages are dispersed in large areas. There is a situation. Therefore, it is necessary to supply systematic and quantitative facilities by analyzing villages that do not meet the minimum standards of basic living infrastructure in rural areas and by considering their characteristics. The purpose of this study is to identify the basic living infrastructure facilities of village units and analyze the characteristics of each village for Boeun-gun, Chungcheongbuk-do.

The rapid rural urban migration and aging has generated an over-depopulation problems in rural areas since the 1980s. The purpose of this study constructs the marginal size of rural over-depopulated village through the analysis of the residential disparities such as farmer's ratio, basic life service accessibility, and levels of social and economic factors for each village community. This marginal scale could support evaluating diverse rural policies, which have been planned to apply to the rural development programs at the village level. The major challenges for over-depopulated villages are the lack of basic facilities, production infrastructures and inactive communities in the village. Therefore, the quantitative analysis of rural residential disparities according to rural village scale can provide the criteria for rural over-depopulated villages. We utilized Korea Agricultural Survey Data(2010) including specific residential condition of village level. The present study adopt multinomial-logit model for quantitative analysis of different village scales and decomposition techniques to separate the direct effect by the village scale factor from the endowment effects by regional or area characteristics, and residual effect by unknown factors. The present study found that the minimum scale of a rural over-depopulated village was 40 and 60 houses for the respective conditions of farmer's ratios less than 50% and greater than 75%. It was concluded based on the study findings that threshold scale could support evaluating the diverse rural policies, which have been planned to apply to the rural development programs at the village level.

Space development and utilization must be conducted within a framework of "peaceful uses" principle under Space Treaty. Japan ratified the treaty in 1967, and interpreted "peaceful uses" as "non-military uses" then. A ghost of "peaceful uses" principle has been hung over Japan up to the moment. Japan's space development and utilization has been conducted with genuine academic interest, and therefore Japan did not introduce space infrastructures to national security policy and did not facilitate growth of space industry. When the Cold War ended, Northeast Asian security environment makes Japan difficult to maintain an interpretation as "non-military uses". Besides the change of external security environment, the domestic industry situation and a series of rocket launching failure needed reexamination of Japan's space policy. Japan is gradually changing its space policy, and introducing space infrastructure in a national security policy under a "generalization" theory that gave a broad interpretation of "peaceful uses" principle. Council for Science and Technology Policy (CSTP) adopted a basic strategy of Japan's space policy in 2004. Since then, a long-term report of Japan Aerospace Exploration Agency (JAXA), an investigation report of Society of Japanese Aerospace Companies (SJAC) and a proposal of Japan Business Federation (JSF) were followed. Japan will promote space development and utilization in national security policy with a "strictly defensive defense" strategy and "non-aggressive uses"principle for protection of life and property of Japanese people and stabilization of East Asian countries.

Appraisal is a basic archival function that analyzes values of records and determines the eventual disposal of records based upon their archival values. In electronic records environment, however, appraisal is different from traditional appraisal system that mainly is based on paper records. Since electronic records don't have physical entity and strongly depend on computer technologies, archivists fall into various dilemma in appraisal of electronic records. Moreover, because creation environment of electronic records is remarkably complex and diversified, appraisal of electronic records cannot be done until the later stages of the life cycle of the records. In Korea, appraisal system is founded on the Tables of Transaction for Records Scheduling through which disposal activities of all records are definite in a concrete form. However, there are little institutional infrastructures associated with appraisal of electronic records. Therefore this paper will intend to analyze characteristic features about appraisal of electronic records as a preliminary study for establishing appraisal system of electronic records in Korea. For this purpose, I have firstly compared creation environment of electronic records with traditional creation environment mainly based on paper records, and analyzed differences between appraisal of electronic records and traditional appraisal system based on paper records in view of recordness of electronic record. then I have examined functional appraisal that focuses on functions and activities in which the records are created and used, and discussed about main issues in relation to establishing appraisal system of electronic records.

Bridges are exposed to very severe environment and experience, as service life increased, elevated traffic load and traffic flow, in addition to natural disasters. In comparing to other road structures, bridges may cause more significant damage, such as human-involved accidents, to the society in the event of collapse. A certain level of service shall be necessarily secured to assure the minimum safety of users. The cost for manage and preserve bridges will increase gradually and more restrictions will be loaded to efficiently distribute the limited resources, such as monetary budget and human resource etc. In order to enhance performance and serviceability of bridges with the limited resource, asset management technique has been applied into the bridge management system, which capitalizes the road infrastructures including bridges and assess them in accordance with the government finance report. In the application of asset management, there must be a tool for assess the performance of bridges and this study introduces the basic information on the definition and role of performance measures for asset management for bridges. This research suggests future development direction of performance measure for asset management for bridges in Korea.

Radon radiation exposures in home have been posed as a potential cancer hazard. This research aims to present the basic data of the indoor radon concentration level by examining the radon exhalation rates of wood species. Radon exhalation rates from five commonly used wood species in Korean wood building construction were measured with Continuous Radon Monitor (CRM), Model 1028 (Sun Nuclear Co., USA) using the Closed Chamber Method (CCM). The mass exhalation rate was observed to vary from $0.00089Bq{\cdot}kg^{-1}{\cdot}h^{-1}$ to $0.00181Bq{\cdot}kg^{-1}{\cdot}h^{-1}$, whereas the surface exhalation rate was observed to be $0.00677-0.01517Bq{\cdot}m^{-2}{\cdot}h^{-1}$. The radon exhalation rate of Quercus accutissima Carruth (white oak) which has the highest density showed the highest figure among the five wood species, on the other hand, the rest of four species showed similar results which were similar to the radon exhalation rates of wood in the U.S.A. and Canada. The average of the concentration measured by the CCM represented well up to the second half-life period (7.7 days). Because result of these small quantities seems to indicate that radon exhalation from the tested wood species has almost negligible impact, the main culprit of the high indoor radon concentration is clearly derived from the background of surrounding wood house. Therefore, as a safety precaution, infrastructures made of wood materials should be designed with the consideration of influx of radon and built accordingly. Furthermore, it is highly desirable that wood will be needed to use for furniture and interior finishing material in indoor environment.

점차적으로 소프트웨어의 복잡도는 높아지고 그 생명주기는 짧아지므로, 기존의 검증된 소프트웨어 요소를 재사용 하는 것이 필요하다. 그러나 기존의 객체 지향 기술은 광범위한 재사용을 유도하지 못 하였다. 컴포넌트는 객체보다 규모가 크고 특정 도메인에 적합한 특성을 가지므로, 시스템 구조화, 설명 및 개발에 있어 더 나은 수단을 제공해 준다. 또한 그 규모나 재사용성에 있어 새로운 개발환경인 분산 시스템에 더 적합하다. 본 논문에서는 객체지향 시스템을 컴포넌트 기반 시스템으로 변환하는 프로세스를 제안하였다. 해당 프로세스는 두 단계로 나뉜다. 우선, 클래스들 간의 합성 및 상속 관계를 이용하여 기본 컴포넌트를 생성한다. 그 후 기본 컴포넌트와 컴포넌트화 되지 않은 클래스들에 대해 본 논문에서 제안된 정적 메트릭과 가이드라인을 이용하여 정제하여 컴포넌트 기란 시스템으로 변환한다.

This study aims to analyzes the Relationship Between Community Consciousness and Residents' Participation in Tourism Development. Starting in 2004, the Rural Tourism Development Project, which has been promoted in Korea, is taking a bottom-up approach that values the participation of residents. And Resident's Participation is also an important criterion for selecting business sites. As the farming community becomes more modern, the community consciousness is declining. But Community consciousness is an important factor for the sustainable maintenance of rural villages. And if community members share a sense of homogeneity, they can identify problems that communities have, and they can solve them with responsibility. Community consciousness can be called the basic infrastructure of residents' participation. Rural tourism feature different characteristics from other tourist areas in that the residential space of local residents is the destination of the tours. As a result, the influence on tourism development is directly affected, so the attitude of local residents is an important success factor unlike other tourism developments. The study analyzed the community consciousness and participation in Tourism Development, which is a significant success factor in rural areas. The survey which included 200 residents of the DMZ Peace Village Site, was concluded that the member's perception and ttachment among Community Consciousness affected the Residents' Participation, and that Economic Influence among tourist development attitudes affected the Residents' Participation. It based on the results in rural tourism development for the residents' participation should be considered with a plan to enhance the economic life satisfaction and promote the economic impact on the area.

지진시 사회 인프라시설물의 피해는 시설물 자체의 피해보다 사회 전반에 걸친 2차 피해를 야기한다. 그 중, 지하 공동구 구조물은 통신, 가스, 전기 등 사회의 라이프라인에 해당하여 지진에 대한 취약성을 정확히 평가하여야 할 필요가 있다. 따라서, 본 연구에서는 지하 공동구의 지진 발생 지반가속도에 따른 파괴가능성을 평가하였다. 평가를 위한 입력지반운동은 해외 실측 지진데이터와 한반도에서 발생가능한 인공지진파를 차용하였으며, 지진해석 방법은 응답변위법과 시간이력해석법을 사용하였다. 파괴여부를 판별하는 한계상태는 휨모멘트와 전단 파괴를 바탕으로 하였다. 취약도 함수 도출을 위한 방법은 최우도법이 사용되었으며, 그 분포함수는 대수정규분포로 가정하였다. 이는 지진시 지하 공동구 시설물의 피해 평가는 물론 지하 공동구 시설물의 내진설계를 위한 기초자료로 활용될 수 있다.
