강수량은 수문 순환의 결정적인 연결 고리이며 공간적, 시간적 변화는 매우 크며, 또한 전 세계적인 범위의 강수량 자료는 지구상의 수문 순환에 대한 이해와 날씨 및 기후 예측을 위해 필요하다. 그리고 지역적 강수량에 대한 지식은 사회 복지에 필수적이다. 지상에 있는 강우관소에서 관측된 강우는 본질적으로 강우의 공간적 불균일성을 반영하기 어려우며, 관측 주기가 하루 이상으로 긴 경우에는 홍수와 연계한 생태-수문학 연구에 적용하는데 한계가 있다. 또한, 지상계측 방법은 해양, 극지방 및 산악지역의 강수량을 관찰하는데 어려움이 있다. 이에 반하여 원격탐사 기술은 지구 강수를 관찰하는데 많은 도움을 주는 기술로 인식되고 있다. 위성자료를 이용한 강우 추정은 지상 강우관측소 및 기상레이더와 비교하여 광역적 공간범위를 대상으로 하며, 지속적이고 균일한 강우를 생산한다는 장점을 갖고 있다(Hong et al. 2016). 위성강우 자료는 일반적으로 전 세계 강수량에 대한 지식과 글로벌 수문순환에 대한 연구를 촉진하고 있으며, 특히, 동아시아, 동남아시아, 아프리카 등지에는 수문학적 미계측 지역이 많기 때문에 위성강우 자료를 이용한 강수량 평가에 대한 연구가 다수 진행되고 있다(Hoscilo et al., 2015; Dembélé et al., 2016; Dandridge et al., 2019; Kim et al., 2019; Yuan et al., 2019). 본 연구는 위성으로부터 유도된 강수자료 중 NASA의 IMERG, NOAA의 CMORPH, 그리고 일본 JAXA의 GSMaP의 위성강우자료와 국내의 ASOS 시간강우자료의 비교를 통해 위성강우의 정확도를 평가하는 것을 목적으로 하고 있다. 분석 결과 총강우에 대한 편이는 그림 1에서 보는바와 같이 CMORPH가 가장 작고 가장 최근에 제공되기 시작한 IMERG 강수자료가 가장 큰 것으로 분석되었다. 지상계측강우와의 상관계수는 1시간 및 3시간의 시간해상도에서 2019년 18호 태풍 미탁(Mitak)의 경우 IMERG 및 GSMaP 각각 0.63 및 0.60와 0.73 및 0.70으로 분석되었다.

COVID-19 is threatening the safety of ships and seafarers by delaying seafarer rotation. Shipping companies and governments have a blindspot in case of the onboard environment of seafarers. An effective, alternative plan should be devised to eliminate the possibility of human accidents in an emergency that threatens the safety of seafarers. According to the survey of former and current seafarers, the most important factor in boarding life was safety, and the most necessary thing during emergencies was to secure smooth seafarer rotation rather than improve wages and welfare. By analyzing the major routes of national shipping companies by continent, ports with a large number of calls and a high Air Connectivity Index were selected as the base port. In addition, the route was designed for effective, domestic seafarer rotation during international shipping. Other countries must be consulted to establish a travel route linking ships, ports, and airports for the safe return of sailors to their home countries during an emergency. In addition, it is necessary to work together for the seafarers who are in trouble of seafarer rotation through cooperation with the International Maritime Organization(IMO). Starting with this, the government should have a monitoring system for the return and non-return routes as well as the number of seafarers on board. If such a system is established, it will be able to determine the response direction of our country's policy in case of an emergency. Along with the shipping company's ef orts to improve the treatment of seafarers, national and social attention will be needed to review domestic laws and improve awareness about seafarers.

This study delves into the geopolitical tensions surrounding Ukraine throughout modern European history, aiming to shed light on its significance in geopolitical discourse. Since the 19th century, European powers, particularly the Anglo-Saxons and Germans, have formulated distinct geopolitical strategies concerning the Eurasian continent, with Ukraine at its focal point. The Crimean War and the German-Soviet War serve as key events to analyze these powers' geopolitical ambitions and interests. The British Empire, driven by its doctrine of thwarting land powers with sea power, intervened in the Crimean War against Russia. Its objective was to disrupt Russian dominance over Ukraine, thereby hindering Russian expansion into the Black Sea and Central Europe. On the other hand, the Third Reich of Germany, fixated on creating a European sphere exclusive from Anglo-Saxon sea powers and the Russian land power, initiated the German-Soviet War. This move aimed to secure a vast territory, including Ukraine, to facilitate expansion into the Caucasus and establish a buffer zone against the Soviet Union. Three key insights emerge from this analysis. Firstly, the absence of a dominant power rooted in Ukraine since the fall of the Principality of Kiev made geopolitical clashes inevitable. Secondly, these clashes ultimately result in a hollow victory for all involved parties, signifying the high costs and minimal gains of such confrontations. Lastly, the root cause of these clashes lies in the discord between exclusive geopolitical visions that fail to accommodate sustainable coexistence among diverse geopolitical spheres. In essence, the study underscores Ukraine's pivotal role in shaping European geopolitics and highlights the recurring clashes driven by competing visions of dominance and control over its territory. From the Crimean War to the German-Soviet War, the struggle for influence over Ukraine reflects broader geopolitical dynamics and the pursuit of strategic advantage by major powers. Ultimately, the study emphasizes the enduring significance of Ukraine in European geopolitics and the complexities inherent in managing its geopolitical tensions.

In this study, the corelation among the knowledge of and attitude to health care and the actual health protective practices of seafarers was surveyed and analyzed in order to provide the management method for improving seafarers' health care. The subjects of this study were 516 seafarers who took refresh training courses in Korea Institute of Maritime and Fisheries Technology. The questionnaire was constructed under the Guidelines for National Health of the Ministry of Health and Welfare and modified for studying seafarers' health state. The collected data were analyzed by SPSS package. The results were as follows: 1) The older, married, religion believer, higher ranker, the man who have longer career have the higher degree of knowledge, attitude, and practice-degree(p<0.05). 2) The degree of knowledge, attitude, and practice are $4.24{\pm}0.35$, $3.45{\pm}0.41$, and $3.39{\pm}0.22$ in mean by 5-score scale, respectably. 3) The corelation among the degree of knowledge, attitude, and practice was significant(r=0.33~0.63, p<0.05).

This study deals with the rent-seeking behavior that exist in cultural voucher from the viewpoint of culture and arts management. Art organizations open to consumers, producers and governments of the arts are dependent on the internal and external influence of an open system. Researcher has found rent-seeking in the course of introducing policies and legalization of the cultural voucher business which has been promoted in the direction of democratization of culture or cultural democracy. Cultural voucher business is a legal term. Although the government has increased the budget or tried to change the policies of the cultural voucher business, the implementation of the cultural voucher business has been opposed to the diversity of consumption and equity as the consumption of genre and the concentration of the capital region have increased. These results were structurally related to the process of legalization and rent-seeking behavior in bureaucracy. This study reaffirms that the efficient operation standard of the cultural voucher business is a balance between the choice of the beneficiary, the competition of the supplier, and access to the cultural voucher. And the theory of rent-seeking was applied as a criterion to analyze this balance. Thus, it is suggested that the criteria of evaluation and improvement to check the conservativeness of bureaucrats are needed to establish a legal system applied to the purpose of 'cultural democracy' and 'democratization of culture' ideology and to guarantee individual creativity and autonomy.

With a view to providing a high-quality policy information service beyond the existing national task service of the national policy information portal (POINT) of the National Library of Korea Sejong, it would be necessary to effectively provide the policy data needed for the implementation of the new national tasks. Accordingly, in this study, an attempt has been made to find a way to connect and develop the BRM-based national tasks and the policy information contents. Towards this end, first, the types of national tasks and the contents of each field and area of the government function's classification system were analyzed, with a focus placed on the 120 national tasks of the new administration. Furthermore, by comparing and analyzing the national tasks of the previous administration and the current information, the contents ought to be reflected for the development of contents related to the national tasks identified. Second, the method for linking and collecting the policy information was sought based on the analysis of the current status of policy information and the national information portal. As a result of the study, first, examining the 1st stage BRM of the national tasks, it turned out that there were 21 tasks for social welfare, 14 for unification and diplomacy, 17 for small and medium-sized businesses in industry and trade, 12 for general public administration, 8 for the economy, taxation and finance, 6 for culture, sports and tourism, science and technology, and education each, 5 for communication, public order and safety each, 4 for health, transportation and logistics, and environment each, 3 for agriculture and forestry, 2 for national defense and regional development each, and 1 for maritime and fisheries each, among others. As for the new administration, it is apparent that science technology and IT are important, and hence, it is necessary to consider such when developing the information services for the core national tasks. Second, to link the database with external organizations, it would be necessary to form a linked operation council, link and collect the information on the national tasks, and link and provide the national task-related information for the POINTs.
