The purpose of this study is to show a course development of the marine leisure sport policy in Korea. The preceding researches and the analysis on the actual conditions on marine leisure sport in Korea were conducted for this research. And analyzing the obstacle and development factors in marine leisure sport, the conclusions intended to provide the preliminary data on the marine leisure industry are as follows: First, as policy-based problems, there will be needs for the public perception improvement in the marine culture caused by the lack of publicity, the reflection reinforcement of the national policy on the marine leisure industry, the prevention of the overlapping investment for the national resources development in the marine industry and marine leisure sport complexes, and the reinforcement of the close networks with the developed countries. Second, as human-based problems, there will be needs for the new organization of the specialty agencies involved in the marine leisure industry field, the nurture of the capable specialists and the reinforcement and nurture of TF team for the infrastructure industry. Third, as facility-based problems, there appeared to be the expansion of the SOC related to the marine leisure, the ease of the laws and regulations for the development of the marine leisure facilities, the prevention of the thoughtless development caused by close cooperation system with the local government. Fourth, as law and institution-based problems, there appeared to be the abolishment of the regulation-centered laws involved in them, the prevention of the legal and institutional confusion caused by policy confusion. Fifth, as industry-based problems, there must be the expansion of the domestic supply and demand, the reinforcement of parts industry and the nurture of the license system for the mechanics on the vessels and the engines.

This study investigated the current status of the management system for foreign seafarers boarding Korean ocean-going vessels and analyzed the problems and suggested measures for improvement through the survey of shipping companies, ship management companies, crew manning companies and related associations. The conclusion is summarized as follow. First, it is necessary to reorganize and apply the collective agreements or the laws applicable to the foreign seafarer separately in regard to the foreign seafarer related laws and collective agreements applied in the same way as the Korean seafarer. Second, it is necessary to change the decision-making to shipowner in deciding on the number of foreign seafarers employed by the Korean ocean-going vessels or if the decision-maker remains the same, the relevant laws must be clearly defined pertinent to the decision-maker. Additionally, the number of foreign seafarers should be applied for each position and ship's type. The third is to expand the recognition arrangement for certificate of ships' officers to Eastern Europe and Asian countries to expand the range of options for hiring foreign seafarers. The fourth is to prevent the waste of administrative manpower by simplifying complicated and unnecessary administrative procedures from hiring and boarding of foreign seafarers. The fifth is to establish a systematic training and education system for foreign seafarers in cooperation with related shipping companies and government authorities, associations and so on. This study will contribute to providing a more efficient and systematic management of foreign seafarers boarding Korean ocean-going vessels.

In the numerical simulation of wave fields using a multi-phase flow model that considers simultaneous flows of materials with different states such as gas, liquid and solid, there is need of an accurate representation of the interface separating the fluids. We adopted an algebraic interface capturing method called tangent of hyperbola for interface-capturing(THINC) method for the capture of the free-surface in computations of multi-phase flow simulations instead of geometrical-type methods such a volume of fluid(VOF) method. The THINC method uses a hyperbolic tangent functions to represent the surface, and compute the numerical flux for the fluid fraction functions. One of the remarkable advantages of THINC method is its easy applicability to incorporate various numerical codes based on Navier-Stokes solver because it does not require the extra geometric reconstruction needed in most of VOF-type methods. Several tests were carried out in order to investigate the advection of interfaces and to verify the applicability of the THINC method to wave fields based on the one-field model for immiscible two-phase flows (TWOPM). The numerical results revealed that the THINC method is able to track the interface between air and water separating the fluids although its algorithm is fairly simple.

This study is written to bring the proposal forward for the direction of south korean naval force. The political situation and the circumstance of the world, especially in the area of Pacific Ocean, are changing very rapidly. North Korea has been always the conventional existing intimidator for South Korea since the 6·25-War. Additionally, the strengthening movements of the national defense, which is easily noticed from China and Russia, is also an other part of intimidating countries against South Korea. Those three mentioned countries are continually developing the asymmetrical warfare systems, for example a strategic nuclear weapon. Since the Obama Administration, the Asia-Pacific Rebalancing-Strategy has been changed as an East Asian foreign policy. Nowadays, Trump Administration renamed the 'United States Pacific-Command' to 'United States Indo-Pacific Command'. The purpose of this is not only letting India to participate in american alliance, but also reducing an economic burden, which is often mentioned in USA. West Germany was located in the very similar geopolitical position during the Cold War just like South Korea these days. And that's why the strategy of West German Navy is worthy of notice for south korean naval force to decide its suitable strategy. Most of all, the two most important things to refer to this study are the plan to expand naval air force and the realistic political stand for us to take it. In conclusion, I laid an emphasis on maintenance of 'green-water-navy'. instead of selecting the strategy as a 'blue-water-navy'. The reason I would like to say, is that south korean navy is not available to hold the unnecessary war potential, just like Aircraft-Carrier. However, this is not meaning to let the expansion of naval force carelessly. We must search the best solution in order to maintain the firm peace within the situation. To fulfill this concept, it is mostly very important to maintain the stream of laying down a keel of destroyers, submarines and air-defense-missile, as well as the hight-tech software system, taking a survey of 4th industrial revolution. Research and development for the best solution of future aircraft by south korean navy is likewise necessary. Besides, we must also set the international diplomatic flexibly. As well as maintaining the relationship with US Forces, it is also very important to improve the relationship with other potential allied nation.

Recently, owing to the increasing demand on the simplification of arrival and departure procedures, IMO's (International Maritime Organization) Facilitation Committee (FAL) is carrying out the standardization project of arrival and departure formalities and clearance form. Also, many port authorities of developed countries are making active researches for the smooth flow and efficiency of the information inbound and outbound ships by way of simplifying their formalities or through electronic means. However, this standardization project cannot be done by one country but by mutual cooperation among related nations. And to carry out this task, the first thing to be done is to standardize the formalities and document form, and to integrate information. To this end, this study has reviewed the model cases of advanced ports of developed countries with regard to their simplification and standardization efforts. And also we have analyzed the formalities and clearance form of the three countries Korea, China, and Japan. And then for the solution of common problems of three countries, this paper has suggested an ebXML-based Global Port B2B framework. Through this framework, we can reuse and automate the necessary information on the arrival and departure of ships, consequently realizing simplification, and laying a foundation for the introduction of e-commerce to the port industry.

This article explores why the two Southeast Asian countries, Vietnam and the Philippines, choose different strategies to cope with the Chinese threat. Despite the evident Chinese threat in the South China Sea, Vietnam has not meaningfully expanded the military cooperation with the United States, whereas the Philippines, ironically, has distanced itself with its ally, the United States. Existing studies on the topic does not offer a satisfactory explanation. We assign that two cases are examples of "underbalancing" - the failure of balancing even though there is an evident threat. Furthermore, we demonstrate the difference between cases of the Philippines and Vietnam by arguing that the number of veto players affects the outcome of foreign policy, underbalancing of two countries. The Philippines has only one veto player, the president, hence its response to external threats is incoherent. On the other hand, the number of veto players in Vietnam is more than one and those players demand negotiation among them on the matter of foreign policy. Upon analyses on two cases we argue that the former is the case of underbalancing caused by a lack of policy stability, while the latter is the case of underbalancing caused by a lack of policy responsiveness.

This study examines the efficiency of safety management measures taken in coastal waters to prevent coastal accidents. Recent years have witnessed about 800 cases of large and small coastal accidents in coastal waters annually. On average, these accidents have been responsible for 129 deaths annually, Thus, there is a need for effective preventive measures. Accordingly, the Korea Coast Guard enacted the Coastal Accident Prevention Act in 2014 and has cooperated with related organizations, such as local governments and the Ministry of Oceans and Fisheries, to safely manage coastal waters. However, compared to the rapid increase in human coastal activities, coastal accidents continue to occur due to the lack of a safety mindset among the Korea Coast Guard, a lack of public safety awareness, a lack of safety management facilities, and poor interest from related organizations, among others. This study examines the conditions and problems faced with regard to safety management in coastal waters based on recent coastal accident data, and analyzes foreign coastal waters safety management cases. Various methods to improve the safety management efficiency in coastal waters are proposed, such as enhancing the safety mindset and capabilities of the Korea Coast Guard, strengthening cooperation among related organizations, increasing the role of local governments, expanding and strengthening safety management facilities by applying new technologies, inculcating a culture of maritime safety, and activating private-public collaborative governance.

This study is to develop the direction of the development of the next-generation mapping of marine information required to develop a base of the utilization localization of maritime production tools. The GIS data-processing products and technologies currently used in the Korea's marine sector depend on external applications which is renewal costs, technical updates, and unreflected characteristics. Meanwhile, the S-100 standard, the next generation hydrographic data model that complements S-57's problems in marine GIS data processing, was adopted as a new marine data standard. This study aims to present the current status and problems of marine GIS technology in Korea and to suggest the development direction of GIS software based on the next generation hydrogrphic data model S-100 standard of IHO(International Hydrographic Organization). S-100-based marine GIS localization technology development and industrial ecosystem development research is expected to scientific decision-making on policy issues that occur with other countries such as marine territory management and development and use of marine resources.

In south Korea, the so-called 'conservative-liberal' rivalry over the assessment of the government's North Korean policies is seen to be impeding the road to right policy choices. For example, the liberals accused former President Lee Myung-bak's hardline policy of provoking Pyongyang and leading to a deterioration of inter-Korean relations, while the conservatives appreciated it for helping nurture mutually beneficial inter-Korean relations in the longer term by compelling North Korea to observe international norms. However, such debate over the vices and virtues of Seoul's North Korea policies is hardly meaningful as the measuring sticks used by the liberals and the conservatives are entirely different matters. The two major goals South Korea must pursue with its North Korean policies should be 'peaceful management of division' and 'change in North Korea'. The former is related to maintaining stability within South Korea and promoting co-prosperity with North Korea. For this, the nation needs to engage, encompass and assist the Pyongyang regime. The second goal is also necessary since South Korea, as a divided nation, must seek a unified Korea under the system of democracy and market economies by bringing change in North Korea. For this, South Korea needs powerful leverages with which it can persuade and coerce the North. This means that the nation is destined to simultaneously chase the above-mentioned two goals, while also both recognizing and negating the legitimacy of the North Korean regime. This situation necessitates Seoul to apply flexibility in reconciling with Pyongyang while applying firm principles to sever the vicious circle involving the North's military provocations. The May 25 Measures, which banned trade and economic cooperation with the North except those related to humanitarian assistance, were taken as sanctions against Pyongyang for sinking the South Korean corvette Chonan in March 2010. The Measures were taken by the Seoul government immediately after a multinational investigation team discovered evidence confirming that the South Korean naval ship had been torpedoed by a midget North Korean submarine. Naturally, the May 24 Measures have since then become a major stumbling block in inter-Korean exchange, prompting opposition politicians and concerned entrepreneurs to demand Seoul to unilaterally lift the Measures. Given the significant damages the Measures have inflicted on inter-Korean economic relations, removing them remains as homework for both Koreas. However, the Measures pertains to the 'principles on national security' the Seoul government must adhere to under all circumstances. This is why North Korea's apology and promises not to repeat similar provocations must come first. For now, South Korea has no alternative but to let North Korea solve the problems it has created. South Korea's role is to help the North do so.

This study examined the concepts of the Internet of Things(IoT), the major issue and IoT trend in the domestic and international market. also reviewed the advent of IoT era which caused a 'Paradigm Shift'. This study proposed a solution for the appropriate corresponding strategy in terms of Enterprise. Global competition began in the IoT market. So, Businesses to be competitive and responsive, the government's efforts, as well as the efforts of companies themselves is needed. In particular, in order to cope with the dynamic environment appropriately, faster and more efficient strategy is required. In other words, proposed a management strategy that can respond the IoT competitive era on tipping point through the vision of paradigm shift. We forecasted and proposed the emergence of paradigm shift through a comparative analysis of past management paradigm and IoT management paradigm as follow; I) Knowledge & learning oriented management, II) Technology & innovation oriented management, III) Demand driven management, IV) Global collaboration management. The Knowledge & learning oriented management paradigm is expected to be a new management paradigm due to the development of IT technology development and information processing technology. In addition to the rapid development such as IT infrastructure and processing of data, storage, knowledge sharing and learning has become more important. Currently Hardware-oriented management paradigm will be changed to the software-oriented paradigm. In particular, the software and platform market is a key component of the IoT ecosystem, has been estimated to be led by Technology & innovation oriented management. In 2011, Gartner announced the concept of "Demand-Driven Value Networks(DDVN)", DDVN emphasizes value of the whole of the network. Therefore, Demand driven management paradigm is creating demand for advanced process, not the process corresponding to the demand simply. Global collaboration management paradigm create the value creation through the fusion between technology, between countries, between industries. In particular, cooperation between enterprises that has financial resources and brand power and venture companies with creative ideas and technical will generate positive synergies. Through this, The large enterprises and small companies that can be win-win environment would be built. Cope with the a paradigm shift and to establish a management strategy of Enterprise process, this study utilized the 'RTE cyclone model' which proposed by Gartner. RTE concept consists of three stages, Lead, Operate, Manage. The Lead stage is utilizing capital to strengthen the business competitiveness. This stages has the goal of linking to external stimuli strategy development, also Execute the business strategy of the company for capital and investment activities and environmental changes. Manege stage is to respond appropriately to threats and internalize the goals of the enterprise. Operate stage proceeds to action for increasing the efficiency of the services across the enterprise, also achieve the integration and simplification of the process, with real-time data capture. RTE(Real Time Enterprise) concept has the value for practical use with the management strategy. Appropriately applied in this study, we propose a 'IoT-RTE Cyclone model' which emphasizes the agility of the enterprise. In addition, based on the real-time monitoring, analysis, act through IT and IoT technology. 'IoT-RTE Cyclone model' that could integrate the business processes of the enterprise each sector and support the overall service. therefore the model be used as an effective response strategy for Enterprise. In particular, IoT-RTE Cyclone Model is to respond to external events, waste elements are removed according to the process is repeated. Therefore, it is possible to model the operation of the process more efficient and agile. This IoT-RTE Cyclone Model can be used as an effective response strategy of the enterprise in terms of IoT era of rapidly changing because it supports the overall service of the enterprise. When this model leverages a collaborative system among enterprises it expects breakthrough cost savings through competitiveness, global lead time, minimizing duplication.
