This paper details the maritime accidents that occurred in the Philippines from 1972 to 2010. Firstly, it describes the general maritime situation in the country. It was followed by the traffic and safety infrastructure and the prevailing weather in the archipelago. The third section deals with the accidents' statistics and their geographical locations which is further sub-divided into three regions. It is grouped according to 10-year period. This paper describes the actual maritime situations, the pertinent national regulations, the inter-agencies policies and their safety regimes. It illustrates the shipping environment in the country including the maritime aids and infrastructure and the on human element factors.

이 연구는 IPA 기법을 적용하여 민간경비원들의 여가활동 집중개선 종목을 도출하고, 나아가 여가제약이 참가지수에 미치는 영향을 규명하는데 주된 목적이 있다. 본 연구는 2010년 서울 소재 6개소 민간경비업체를 대상으로 판단표집법을 적용하여 최종분석에 사용된 사례 수는 총 267명이다. 결론은 다음과 같다. 첫째, 민간경비원들의 여가활동 참가 지수인 선호도와 참여도는 차이가 있다. 중점개선 여가활동은 헬스, 산책/조깅, 숙박관광, 당일여행 등이다. 둘째, 민간경비원들의 여가제약은 여가활동 참가지수에 영향을 미친다. 개인내적, 주변의식적, 대인적 제약이 클수록 선호하는 여가활동에 부적 영향을 미치는 반면, 구조적, 시간 경제적 제약을 극복하고 선호하는 여가활동에 정적 영향을 미쳤다. 본 연구결과를 토대로 민간경비원들의 복지적처우개선에 집중적인 투자가 이루어져야 할 것이다.

This paper considers a continuous-review two-echelon inventory control problem with one-to-one replenishment policy incorporated and with lost sales allowed where demand arrives In a stationary Poisson process The problem Is formulated using METRIC-approximation in a combined approach of pricing and (S-1.S) Inventory policy, for which an iterative solution algorithm is derived with respect to the corresponding one-warehouse multi-retailor supply chain. Specifically, decisions on retail pricing and warehouse inventory policies are made in integration to maximize total profit in the supply chain. The objective function of the model consists of sub-functions of revenue and cost (holding cost and penalty cost). To test the effectiveness and efficiency of the proposed algorithm, numerical experiments are performed The computational results show that the proposed algorithm is efficient and derives quite good decisions

Purpose: In this study, we analyzed the correlation between high-caffeine energy drink intake and mental health in high school students. Methods: Analyses were conducted using the data of 27,097 responses from the 2015 Korea Youth Risk Behavior Web-based Survey of general high school students. Data were analyzed by logistic regression based on a complex sample design. Results: High-caffeine energy drink intake was positively correlated with the rates of smoking, alcohol consumption, violence, depression, and suicidal thoughts and negatively correlated with the sense of happiness. Conclusion: High-caffeine energy drink intake has a significant impact on the mental health of high school students. Therefore, in-depth research and policies on high-caffeine energy drink intake and the mental health of young individuals are required.

The major problems of chemical fertilizer supply and consumption involved in price policies since the end of World War II in Korea and their solutions were extensively discussed. The period was divided into three sub-periods: 1946-1960, 1961-1967 and 1968 to present. Since 1968 when the operations of three large-scaled fertilizer plants: Yongnam Chemical Co., Chinhae Chemical Co. and Hankuk Fertilizer Co. were begun in full scale, the domestic supply of nitrogen and phosphate fertilizers were almost enough for the domestic demand. However, since 1976, when Namhae Chemical Co. was added to the production capacity, the fertilizer industry has been faced with the overproduction problem of nitrogen, and the high production cost due to high petroleum price, which gave financial difficulties. Several policy directions and alternative measures for solving the current problems were also suggested in this presentation.

The paper deals with the emergence of creative industries in Germany in the last decade and points out the recent development of creative industries at examples from different sub-segments. Recent national and regional policies are reflected and the importance of creative industries in relation to other economic branches will be discussed. Key factors for the development of creative industries are highlighted based on a literature review and a compilation of several empirical research studies. The paper points out the role of Science & Technology Parks for the development and further development of creative industries, based on German experiences. Finally, the conclusion deals with some ideas to facilitate the impact of Science and Technology Parks on creative industries in Germany.

In this paper, we propose a Bayesian approach to determine the adaptive preventive maintenance(PM) policy for a general sequential imperfect PM model proposed by Lin, Zuo and Yam(2000) that PM not only reduces the effective age of the system but also changes the hazard rate function. Assuming that the failure times follow Weibull distribution, we adopt a Bayesian approach to update unknown parameters and determine the Bayesian optimal sequential PM policies. Finally, numerical examples of the optimal adaptive PM policy are presented for illustrative purposes.

U.S. lawmakers tend to organize sub-party groups focusing on regions, ideologies, policies, and foreign affairs. Examples include the conservative Freedom Caucus loyal to Trump and the Congressional Black Caucus promoting the interests of African Americans. Then how do these legislative groups affect the making of U.S. foreign policy? Paying special attention to the Korea caucus in U.S. Congress, we have analyzed the sources and processes of congressional caucus and foreign policy and have learned that structures and activities of the caucuses differ from one another. The Korea caucus seems to be a bipartisan group that focuses on issues such as trade, travel, and troubles provoked by Pyongyang. However, the Korea caucus is not really a solid voting bloc for policy alternatives; it is instead more of a constituency-oriented legislative group that prioritizes local interests. This research underscores the need for systematic and comprehensive study of U.S. legislative politics and foreign policy.

Since the sub-prime mortgage crisis from the US in 2008, the Korean housing market has plummeted. However, the deposit prices of the Korean local lease contract, Chonsei, had been increasing. This increase of Chonsei prices can be a threat to low-income people, most of whom prefer to live in houses with a Chonsei contract. In the housing and Chonsei market, there are many stakeholders with their own interest, hence, simple thoughts about housing and Chonsei market, such as more house supply, will decrease house price, would not work in a real complex housing market. In this research, we suggests system dynamics conceptual model which consists of causal-loop-diagrams for the Chonsei market as well as the housing market. In conclusion, the Chonsei price has its own homeostasis characteristics and different price behavior with housing price in the short and long term period. We found that unless government does not have a structural causation mind in implementing policies in the real estate market, the government may not attain their intended effectiveness on both markets.
