After Liberation of Korea, Korean fisheries economy fell into an exhausted conditions because of the damage of Japanese colonization policy and the Korean War, and fisheries organizations of those days established for the improvement of fishermen's welfare could not carry out their primary purposes and functions. Under such circumstances, Fisheries Cooperatives starting on April 1st in 1961 played a great role in settling the socio-economic confusion of those days. Fisheries financing was also more systematic and substantial after establishment of Fisheries Cooperatives. In fact fisheries industry was faced with much more riskiness than any other industry on account of its speciality and such a riskiness induced general financial institutions to be reluctant to lend money to the fishermen. In order to overcome such a capital rationing, it was necessary to establish the reciprocal financing system based on the principle of mutual protection of economic weakers. Credit business in Fisheries Cooperatives beginning in 1963 was mainly dependent on governmental fund as fund sources. But the size of fund was too small to satisfy fishermen's fund demand, therefore Fisheries Cooperatives carried out the movement of raising its own fund. As a result of the movement the ratio of its own fund to total funds amounted to 47.7% in 1980, but external funds still take a greater part of all funds. To settle the weakness of the ratio of its own fund and chronic deficiency of fund, a conclusion can be drawn as follows : 1. The enlargement of Fisheries Cooperatives' raising ability of funds. .The expansion of urban branch to absorb idle funds in urban area. .The diversification of financing service to compete with genetral financial institutions. 2. The enlargement of governmental fund and preferential treatment of fishermen's savings. 3. Vitalization of mutual finance and fixation of Fisheries Cooperatives' two-phase organization. 4. The re-enforcement of supervisory financing and post management system.

폴리올레핀 공정의 melt index(MI or MFI)는 제품의 품질을 결정짓는 가장 중요한 제어변수이다. MI는 실시간으로 측정하는 것이 어렵기 때문에 MI를 예측하여 상관관계를 나타내고자 하는 많은 방법들이 제안되었다. 본 연구에서는 시스템 인식기법을 바탕으로 MI 예측을 위한 새로운 1차의 동적 예측모델을 고안하였다. 이 모델의 예측성능은 등급변경이 수반되는 고밀도 폴리에틸렌 공장의 실제 운전데이터에 근거한 모사로 검증하였으며 다른 예측방법들과의 비교로부터 본 연구에 의한 예측모델의 우수성을 확인하였다. 구성된 MI 동적 예측모델을 토대로 하는 모델예측제어방법의 적용을 통하여 각 단위공정별 MI를 계산하고 운전데이터와 비교하였다. 제어운전의 모사를 통하여 등급변경이 이루어지는 운전 동안의 전이시간과 불량제품 발생량이 현저한 감소를 보임을 확인하였다.

This study generalized and systemized the unit-project items of 176 project districts for the rural village comprehensive development projects (RVCDP). This paper surveyed opinions of III answerers (7 specialists, 43 agents of Korea Rural Community corporation, and 61 agents of local government of cities and counties) in order to determine the classification system and their corresponding weighting values of the project items using analytic hierarchy process (AHP) method. From the results extracted by project plans of 176 project districts for 5 years from 2004 to 2008, this study decided a hierarchical system for unit-project items of RVCDP by AHP method, which consisted of three steps: 4 items for 1st step, 13 items for 2nd step, and 52 items for 3rd step. The first step contains 4 items of Strength of Rural-urban Exchange & Regional Capability (RURC), Green-income Infrastructure & Facility (GIF), Culture-health-welfare Facility, and Eco-environment & Landscape facility (ELF). In the survey of weighting values with AHP method, the analysis result for the first step showed that in opinion of specialists, GIF is more important than the others while in opinion of the other agents, RURC is more important. In the second step, Product Facility is more important in the specialists, whereas Strength of Resident Capability is the most important in the other agents. Analyzed unit project items as the third step, all answerers evaluated that the Education and Excursion for Rural Resident Capability has the highest weighting values.

This article aims to critically review recent U. S. RMA-centered theories of warfare having prevailed after the 1991-92 Gulf War upon which the current ROKA military transformation project, the Vision 2020, largely based. In order to evaluate validity as a universal warfighing theory of NCW (Network Centric Warfare) and EBO (Effects-Based Operations), this article reviews the intrinsic strength and weakness of the theories as well as results of several recent wars that the U. S. Army conducted based on doctrines derived form such theories, In addition, this article examines the impact of certain military technology or weapon system in some well-known historical wars to draw lessons regarding the relationship between technology(weapon system) and military victory. Historical examples has shown that victories in war were not achieved by new technologies alone in most cases. Rather military victories tended to owe to combination of new technology, original doctrine and well conceived organization. Although the U. S. Armed Forces showed brilliant records of operational successes anchored on the system of PGMs and NCW concepts in Iraq (1991-92; 2003) and Afghanistan (2001-02), it must be pointed out that the operational successes did not bring about political ones in cases of Iraq and Afghanistan. It reminds us of perils of too technologically tilted approach to the conduct of war. In sum, one ought to recognize that superior technology nowadays became a necessary condition of success but is not yet a sufficient condition, the ROKA needs to be abreast with development trends of military technologies and related theoretical concepts, it need not too be in a hurry in adopting cutting edged war-making technologies at the expense of large amount of budget. The essay recommends for the ROKA several basic requirements for coping with conduct of future wars as well as establishing a 'Korean style military thought'; (1) Recognition of importance of technology in conduct of war; (2) Imposition of officer self-study hours in working days; (3) Establishing a lifestyle of military professionalism in the Korean officer corps; (4) Setting up small or large groups of think-tanks that are specialized in army doctrinal formulation.

The purpose of this study was to investigate perception of the Food Allergy Labeling System (FALS) of school foodservice in female middle school students. The subjects were 148 female middle school students in the Incheon metropolitan area. In this cross-sectional study, data were collected using self-administered questionnaires. Only 20.9% of subjects had experience of food allergy education. There was no significant difference in food allergy knowledge by grade. The scores of perception of food allergy labeling by school foodservice were significantly higher in lower grade students (p<0.001). In all grades, highest scores were observed for 'food allergy labeling is necessary', whereas the lowest scores were for 'I check the food allergy labeling'. The percentages of subjects who wanted to participate in food allergy education were significantly different (p<0.01); 73.8% in 1st grade, 50.0% in 2nd grade, and 35.7% in 3rd grade. For desired education contents to enhance perception of FALS, 57.5% of subjects answered 'emergency management' and 23.0% said 'information of food allergy causing food'. Therefore, it is necessary to increase food allergy education and educate female middle school students according to grade in order to enhance perception of FALS.

고분자 전해질 연료전지는 운전온도에 따라 효율과 출력이 변화하기 때문에 $65^{\circ}C{\sim}75^{\circ}C$정도의 적정 운전온도를 유지하기 위한 냉각시스템을 필요로 한다. 따라서 PEMFC 운전온도를 유지하기 위한 냉각시스템 및 이를 위한 제어로직을 적용할 필요가 있다. HILS는 이러한 냉각시스템 제어로직을 검증하고 연구하기 위한 방법 중 하나이다. 본 논문에서는 냉각수 제어 알고리즘 연구를 위해 HILS 시스템을 구성하였다. HILS 시스템 모델은 PEMFC, 열교환기 및 온도와 관련한 외부환경 모델로 구성되며, HILS 시스템의 하드웨어는 삼방밸브, 펌프, 열교환기로 이루어진다. 이러한 HILS를 활용하여 냉각시스템 제어 효율 향상을 위한 제어우선순위 및 제어 대상온도 설정에 대한 연구를 수행하였다. 1차 냉각회로의 삼방밸브를 우선제어대상으로 설정하고, 2차 냉각회로의 온도제어성능 보정을 위해 2차 냉각회로 삼방밸브의 개도율 하한값을 PEMFC 출력과 2차 냉각회로 냉각수 온도의 함수로 작성하여 온도제어성능을 보상할 수 있도록 하였다. 그 결과 안정적인 PEMFC 온도 제어성능을 확인하였다.

폭발볼트는 각종 유도무기 및 우주발사체에서 결합 및 분리기능을 수행한다. 이처럼 유도무기 체계에서 폭발볼트의 역할은 매우 중요하며, 임무 실패시 체계 전체 실패의 원인이 될 수 있다. 이와 같은 이유로 폭발볼트의 설계 수명 예측에 대한 요구가 최근에 지속적으로 발생하였지만, 신뢰도 높은 예측방법이 제시되지 못하고 있다. 기존의 가속노화 방법을 적용하기 위해선 폭발볼트의 활성화 에너지와 가속계수를 알고 있어야 한다. 현재 가속노화에 필요한 정보를 정확히 확보하지 못한 상황에서 폭발볼트의 설계 수명을 예측하는 것은 어렵기 때문에 본 연구에서는 실제 10년 이상 자연 노화된 폭발볼트를 이용해 성능을 평가하고, 이를 바탕으로 최소한의 설계 수명을 제시하였다.
