Structural flood defensive alternatives have been evaluated based on economic feasibility, riskiness of safety and sustainability. Social problems associated with structural flood defensive alternatives such as dams, flood control channels, etc. are currently issued. The evaluation items of policy presented in KDI(2001) are should be modified in order to resolve the social problems. Hence, this study conducted a questionnaire survey of public servants, researchers, and engineers to obtain how to determine evaluation items for policy assessment and to compute their weights in the analytic hierarchy process. This study also compared the weights of the items in KDI(2000) with the weights from the survey in this study. The policy assessment weight was estimated higher than KDI(2000). This result suggests that social awareness increases and the analysis of policy becomes important for selecting optimal structural defensive alternatives.

해양사고 분석을 위한 해양사고 재결서는 중요한 정보제공의 원천이며 재발방지를 위한 개선사항을 제시한 자료이다. 하지만 이는 보고서 형태로 구성되어 수량화 하여 데이터로 활용하기에는 한계가 있다. 본 연구에서는 이러한 해양사고 재결서를 원인요소와 결과요소로 구분하여 계층화작업을 시행하였다. 이를 통해 충돌사고에서 선박조우상황과 충돌부위와의 상관관꼐를 증명하기 위한 기초자료로 사용하고자 한다. .

중소기업은 국가 및 지역경제의 절대 다수를 차지하는 중추적인 경제주체이며, 국가 경제의 안정적 성장을 위한 근간으로서 이러한 중소기업의 경쟁력 강화는 우리 경제의 지속적 성장을 위한 핵심요소로 볼 수 있다. 본 연구에서는 계층화분석(AHP) 기법을 활용하여 최근 각 지자체 별로 구축되어 운영 중인 중소기업지원 포털의 평가를 통해 중점을 두고 관리해야 할 요소를 구체화시켜 보고자 하였다. 이러한 연구목적을 효과적으로 달성하기 위하여 D시에서 현재 운영 중인 중소기업지원 포털에 대한 우선순위 평가를 통해 시스템의 개선방안 및 향후 타 지자체에서 유사 시스템 구축 시 활용 가능한 시사점을 도출해 보고자 하였다.

본 연구는 선박사고의 발생과 선박이 지닌 특성(선종/톤수/국적)간에 연관이 있을 것으로 가정하여 관제전문가를 대상으로 하는 설문조사 및 사고통계 분석을 통해 각 특성 별 가중치를 계량화하여 기준점수표를 마련하고자 하였다. 가중치 산정은 분석적 계층화 과정(AHP: Anlaytic Hierachy Process)를 거쳤으며 이를 통해 얻은 기준점수표를 바탕으로 인천항의 1일간 입항선에 적용하여 결과를 준사고이력 보유선박군의 점수와 비교하여 양 집단 간 높은 위험지수 해당선박 존재 비율을 비교하였다.

In the recent, due to explosion of Digital Universe, the performance of computer and storage system is reducing. Therefore, the upgrade and capacity expansion needs is growing. Countermeasure for this problem is required fundamental and long-term solutions rather than piecemeal expansion. In this paper, we establish a data management policy for an enterprise through the operational status of storage system and the analysis of data value of it, and implement ILM-based tiered storage system on the basis of these. The results of this study shows the overall throughput was improved about 21% compared to the existing system, it is very effective to maintain continuous quality and reduce operating costs in the long term aspect.

The Total Pollutant Load Management System(TPLMS) in the Han River basin is being changed from a voluntary to a mandatory system. Accordingly, this study suggests directions and priorities for research that can support implementation of TPLMS through an objective approach that deploys gap analysis and analytic hierarchy processes (AHP). Gap analysis indicated that TPLMS in Korea is still focused on compliance with regulations, and that implementation of TPLMS is still in its early stage. Improvements are thus needed in flexibility and effectiveness, including introduction of emissions rights trading, and upgrading to a renewable emissions permit system. The AHP study indicated that R&D will need to proceed in parallel in multiple areas to improve systems and resolve scientific uncertainties. Balanced R&D will be needed in both the institutional and technical groups. Subgroup analysis indicated that developing a reasonable process to establish water quality management targets is of the highest priority in the institutional group. In the technical group, higher priority will need to be given to improving model reliability and developing innovative pollution load reduction technologies.

In heterogeneous networks SVC (Scalabile Video Coding) will be used for IPTV service. This paper analyses how to determine the optimal inter-layer reference scheme according to final level to be displayed in hybrid scalable coding which consists of spatial, quality and temporal layer. It determines where to stop layering quality layer stacks in lower spatial layer according to the relationship between noise induced by loss of high frequency component eliminated by filter in order to get rid of aliasing when spatial layering is processed and noise induced by quantization when quality layering is processed. This paper shows the choice of the level of layering between spatial and quality to get better coding efficiency and then presents what is needed for determining it.

The role of the botanical garden in securing biodiversity, responding to climate change, and sustainable development in modern cities is becoming more important. Private botanical gardens that lead the domestic botanical culture are declining due to complex reasons such as an increase of tourist destinations, lack of policy support, lack of introduction of advanced management strategies, and similar leisure activities to national and public botanical gardens. The Private Botanical Garden not only has a large number of plant species with high conservation value, but also provides various public utilities as a cultural and educational space and government efforts are needed to activate the operation of this amenity. The purpose of this study is to evaluate the value of public functions provided by private botanical gardens using the Contingent Valuation Method (CVM). In this way, the government aims to provide a basis for policy and institutional support for private botanical gardens. The main results are as follows. First, public utility functions provided by private botanical gardens were recognized as 'preservation' (23.4%), 'recreation and tourism' (17.5%) and 'research' (16.6%) in order of analytic hierarchy process (AHP). Second, 'heritage value' (33.0%) and 'existence value' (32.5%) were recognized as significant among the values provided by private botanical gardens. Third, the willingness to pay (WTP) to preserve the public functions of the private botanical garden was 12,234 won. Based on this, the economic value of all private botanical gardens in the whole country was estimated, resulting in about 233.8 billion won. There is a need to revise laws and regulations related to financial support for the revitalization and quality improvement of private botanical gardens. It is also necessary to establish a cooperative operating system between national, public and private botanical gardens.

This study examines many preceding studies on school space, including the high school credit system, and attempts to present the importance after deriving the most appropriate factors when constructing an educational environment of the high school credit system. Based on the derived importance level, the purpose of this study was to provide information that is helpful for the implementation of the educational environment of the high school credit system in each school and to establish and present a model from an academic perspective by deriving the importance of the educational environment according to the high school credit system. As a research method, the importance of the educational environment was analyzed through the Analytic Hierarchy Process. The result of the analysis indicated that it is necessary to consider the interrelationship between the educational curriculum and the educational environment, which selectively and intensively performs functions and maximizes the effect according to the strategic importance of the educational environment.
