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.

In polyolefin processes melt index (MI) is the most important controlled variable indicating product quality. Because of the difficulty in the on-line measurement of MI, a lot of MI estimation and correlation methods have been proposed. In this work a new dynamic MI estimation scheme is developed based on system identification techniques. The empirical MI estimation equation proposed in the present study is derived from the $1^{st}$-order dynamic models. Effectiveness of the present estimation scheme was illustrated by numerical simulations based on plant operation data including grade change operations in high density polyethylene (HDPE) processes. From the comparisons with other estimation methods it was found that the proposed estimation scheme showed better performance in MI predictions. Using the model predictive control method based on the present dynamic MI estimation model, MI values are estimated and compared with those of MI setpoints. From the numerical simulation of the proposed control system, it was found that significant reduction of transition time and the amount of off-spec during grade changes were achieved.

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.

Polymer electrolyte membrane fuel cell(PEMFC) requires cooling system to maintain the proper operating temperature(about $65^{\circ}C{\sim}75^{\circ}C$) because the efficiency and power are affected by operating temperature. In order to retain the operating temperature of PEMFC, cooling system and coolant control logic are needed. Hardware-in-the-loop simulation(HILS) is one of effective methods to study and evaluate control algorithm. In this paper, the HILS system was designed to study the coolant control algorithm. The models of HILS system consisted of PEMFC, heat exchanger, and external environment associated with temperature. The hardwares in HILS system are 3-way valves, pumps, and a heat exchanger. The priority control and the control target temperature were investigated to improve the control performance using HILS. The 3-way valve in $1^{st}$ cooling circuit was selected as priority control target. The under limit value of $2^{nd}$ 3-way valve set as a function of PEMFC power and $2^{nd}$ circuit coolant temperature to correct temperature control performance. As a result, the temperature of PEMFC is stably controlled.

A total of 981 questionnaires were distributed to them, and 888 ones responded to the survey, which had been conducted from Oct. 17, through Oct. 25, 2019. 793 responses were used for the final analysis. The data collected were processed using the SPSS 19.0K for descriptive statistics, T-test, ANOVA, Pearson's correlation coefficient and regression analysis. Findings: First, The type of organizational culture perceived most by hospital employees was 'hierarchy-oriented' (3.53) followed by 'relation-oriented'(3.33), 'task-oriented'(3.23), 'innovation-oriented'(3.19) and job satisfaction scored 3.13, organizational commitment scored 3.28 on their order. Second, 'Relation-oriented', 'task-oriented' and 'innovation-oriented' was positively correlated with job satisfaction and organizational commitment. hierarchy-oriented' was negatively correlated with job satisfaction and organizational commitment. Third, Factors that significantly influencing on organizational effectiveness in a newly established general hospital were as follows. Factors influencing job satisfaction included 'innovation-oriented', 'relation-oriented' and factors influencing organizational commitment included 'relation-oriented', 'innovation-oriented' and age. Practical Implications: In order to increase the organizational effectiveness of the E-General Hospital, it is necessary to gradually move from a hierarchica l-oriented culture to an innovation-oriented and relationship-oriented culture. Since age also affects organizational commitment, it is necessary to promote stability and growth by promoting the mentor-menti system for new members with a low level of experience and experience.

Explosive bolt is coupled in a variety of guided weapons and space projectiles, to perform the separation function. Thus, the role of the explosive bolt in guided weapons systems is very important, as it can cause failure of the entire system in the case of mission failure. For this reason, the design life prediction for explosive bolt is highly and frequently required recently, but its accurate prediction method has not been presented. In order to apply the existing accelerated aging process, we should know the activation energy and the acceleration factor of the explosive bolt. Since the information required for accelerated aging is not presently secured, it is difficult to predict the design life of explosive. Thus, in the present study, we have evaluated the performance of actual explosive bolts in the condition of natural aging over 10 years in order to present a minimum design life.
