The main objective of this research aims at analyzing efficiency of government financial transfers(GFTs) to the Korean fisheries sector, using the Linear Structural Relations model(i.e., LISERL model) and the field survey data. Most policies of GFTs tend to be implemented to protect industries with weak competitive advantages such as infant and/or primary industries. Specific policy instruments include income transfers, government loans with lower interest rates, taxes and the like. Fishing activities are made at a highly changeable natural environment of the ocean with a great amount of risk and uncertainty. Fishing households make their livelihood under the small-scale fisheries. Such fisheries and fishing households have also a relatively weak market power. Because of these fisheries characteristics most coastal states have adopted a variety of government support programs. However, despite such a huge government support, during the past several decades the world fishing communities have seen a tendency of continuous fishereis resource overexploitation. For this resason there have been hot debates over the government support policies for fisheries through OECD, FAO, WTO, and UNEP. In general, policy evaluations tend to be made on the basis of benefit-cost(B/C) analysis. However, the B/C analysis may produce results quite different from real ones primarily due to many unmeasurable effects. Thus, the authors composed simple questionaires and let fishermen, government officials and academic people answer the questions. The survery was made in several ways such as post-mail and personal/group interviews. In recent years, for analysis of policy performances and effectiveness, the LISREL model has often been used, which consists of structural and measurement eqquations. This model has a good advantage of transforming unobservable variables to observable ones so that it helps construct endogenous cause and effect relationships among relevant variables. The evaluation was done from the two aspects: policy results and policy effectiveness. The policy result evaluation showed that there is a need for improvement for policy problem perception and decision-making process, while the policy effect evaluation suggested that the policy goals were successfully achieved and social justice was improved from the perspective of the entire society as well. However, the research results showed that the GFT policies rendered little contrubtion to narrowing down the gap between GFT beneficiaries and non-beneficiaries incomes.

지상국비행종단지령장비는 위성발사체(KSLV)발사 후 비행 중 일어날 수 있는 비상사태 (안전영역을 벗어나거나 지상에서 더 이상 추적이 불가능할 경우)에 대하여 지상통제장치에서 비행종단을 명령하여 비행을 강제로 종단시키는 역할을 한다. 본 글에서는 나로우주센터에서 위성발사체(KSLV) 발사를 위하여 설치 운용될 지상국비행종단지령장비의 설계에 관한 기본사항을 서술하고 있다. 국내 환경에 맞는 최적의 시스템 설계를 위하여 위성발사체의 비행궤적 및 특성을 고려한 운용개념을 먼저 정의하였고, 발사체에 탑재되는 수신부 특성을 고려하여 RF Link Budget 분석 및 송신시스템의 RF 요구 성능, 신뢰도 및 가용도 등을 분석하였다. 본 분석을 바탕으로 위성발사체(KSLV)에 비행종단명령을 안정적으로 생성, 처리하여 전송할 수 있는 각각의 장비를 설계하였다.
