본 연구는 1990년대부터 국내에서 처음으로 시작된 폐광산 지역 지반침하방지기술을 정리하고 향후 지반침하방지기술의 발전방향을 모색해보고자 하였다. 먼저 지반침하의 개념을 정리하고, 지반침하 조사기술, 안정성 평가기술, 보강기술, 계측기술 등 각각의 적용기술을 설명하였다. 현재의 어려운 사업상황을 극복하고 지반침하방지 기술을 발전시켜 나가기 위하여서는 먼저 현재까지 개발된 기술을 통합정리 하고, 공공기관과 민간전문 사업자가 상호 긴밀히 협력하여야 한다. 그동안 다양한 시행착오를 거쳐 발전된 기술을 터널굴착, 토목기반시설물 건설, 지하 환경영향 평가 등과 같은 관련 산업분야에 적용하여 사업영역을 확장해 나가는 것이 필요하다. 또한 좁은 국내시장을 벗어나 그동안 축적된 기술로 해외시장을 개척하여 나아가야 할 것이다.

본 연구에서는 표적의 방향 탐지 오차를 최소화 시키는 방법을 제안한다. 수신 신호 위상차에 오차가 발생하면 표적 방향을 정확히 탐지 할 수 없다. 본 연구 제안 방법은 각 안테나에 입산한 신호에 대해서 실효치를 적용하여 위상을 획득한 후 최적의 신호 대 잡음비를 이용하여 위상 오차를 감소시킨다. 모의실험결과에서 안테나 간격이 반파장일 때, 표적 방향 탐지 확률이 가장 우수하고 신호 대 잡음비가 25dB일 때 방향 탐지 확률의 기존방법은 10-1.7이고 제안 방법은 10-3.3이다. 기존 방법의 표적 탐지 방향은 [-8°,8°]로서 2도의 오차를 나타내고, 제안 방법의 표적 탐지 방향은 [-10°,10°]로서 표적방향을 모두 정확히 탐지한다. 향후 분해능 감소에 따른 위상오차를 감소시키는 방법에 대한 연구가 필요하다.

The aim of this study was to investigate the difficulties that Korean farmers and processors currently experience with respect to the market for Korean native chicken (KNC). This study also provides suggestions by which they can overcome these difficulties. In all, sixty-nine farmers and sixty-two processors participated in our investigation, which addressed 1) the current difficulties that KNC farmers face, 2) the current importance-satisfaction measures among KNC farmers and processors, and 3) the future direction of the KNC market: farmer and processor opinions. The respondents stated that the limited number of sales stores was the most difficult market condition they faced in raising KNC, followed by feed cost, animal disease, and poor production environment. Regarding issues of importance and satisfaction, origin in raising step and slaughtering in the processing and distribution step were considered the areas most in urgent need of improvement, given farmers' and processors' high levels of dissatisfaction with these. Both the free-range farming system and the concept of animal welfare are growing in importance, given consumers' interests in these areas. As to opinions on the direction of KNC development, menu development was cited as most important, followed by public advertisement, accessibilities, business aid, and breed development. Consequently, the results show that well-organized support from both the government and related industries is needed, as chicken farmers and processors cannot resolve certain limitations inherent in the KNC industry on their own.

This study aims at proposing a direction of improving the efficiency in Korean information technology(IT) industry. In the face of re-engineering which has been done in most industries, it is very important to assess the validity of their restructuring or M&A based on the future efficiency. At first, by using the DEA/WINDOW, we will evaluate how the 30 firms are efficient for outputting their performance with respect to the profit realization and market ability. Then, in order to propose the direction of the efficiency improvement and suitable restructuring strategy, we will clarify how the efficiency of IT firms depends on their firm size. Finally, we will analyze their 'economy of scale' and also reveal how their economy of scale depends on the firm size based on return-to-scale(RTS).

As the construction technology is rapidly advancing internationally, the necessity of virtual construction technology development is drastically demanded in the construction industry together with a fusion technology with information technology(IT). The construction technology will be changed as the paradigm of construction technology in the future. The establishment of building structural system in the virtual construction basis is necessary for the integration of construction process, and it will be expected to produce the effect of reduction of construction period and quality improvement through the environment of integration. This study is to present the analysis of the existing process of structural design, the content of research & development as per the building structural system on virtual construction basis and the direction of research.

There is a growing interest on and expansion of rights of people with disabilities. Among them, people with visual impairment show high adaptation to environments in comparison to people with other types of disabilities, thus a large percentage of them live in their own houses rather than residing in a care facility. According to the housing status of people with visual impairment, the ratio of their residence in rural areas is high. In rural areas people who have disabilities often live in poor residential environments, requiring much improvement. However, such improvement is too costly for them to pay, and home modification that does not fully consider the user, may cause less efficiency and another dangerous situation to people with disabilities. The purpose of this study is to delineate empirical lessons for direction of customized home modification for people with disabilities through analysis of process of home modification including the execution as a intervention. This study used qualitative method to examine and analyzed the entire customized home modification process. The conclusion of this study is as follows. First, home modification measures should be derived considering the suitability of the target building for the specific condition of residents. Second, discussions with various stakeholders from the early stage during which proper home modification measure is searched are essential for realizing appropriate customized home modification. This study has significance in that it provides the direction for customized home modification for people with disabilities as well as empirical data that could reduce trials and errors in the future.

This study aims to suggest the improvement strategy of law-system for rural landscape planning. The results are as follows. First, for the establishment of the rural and fishing village landscape planning, it is necessary to change the concept of the scene into Landscape to watch from Landscape to feel from now on. Second, it is necessary to establish a rural and fishing village landscape planning of the local unit to manage the rural and fishing village landscape systematically. In addition, it is necessary to cooperate with the Scenic Conservation Act in contents of the basic planning when we perform rural and fishing village development business. Third, it is necessary to make an extra landscape management planning to consider local landscape resources to develop a rural and fishing village. Finally, with an improvement direction of the plan establishment, the action to practice and management in the future is necessary. This method may do wider public information with establishing the management mechanism of the rural and fishing village landscape.

In this paper, we analyze the quality status of Health and Welfare division's standardized log and asses the characteristics of the institutions' logs analysis to establish the criteria to minimize hazards and control the quality of log's institutional details to limit extraction. As a result, extraction condition's proposed development direction to adequately assess and control health and welfare abuses privacy control target log. This improvement over the status and quality of information shared with relation to institutional work of the log quality characteristics is made possible. In addition, quality control and inspection standards were prepared in accordance with the institutional log characteristics. Future research will include performing continuous analysis and improvement activities on the quality of logs with integrated control of sharing personal information and distributing information about logs' quality to proactively target organ. Therefore, we expect that correcting proactive personal information misuse and leakage is possible to achieve.
