According to the three amended Laws of the Data Economy and the Data Industry Act of Korea, systems for pseudonymous data integration and Data Safe Zones have been operated separately by selected agencies, eventually causing a burden of use in SMEs, startups, and general users because of complicated and ineffective procedures. An over-stringent pseudonymization policy to prevent data breaches has also compromised data quality. Such trials should be improved to ensure the convenience of use and data quality. This paper proposes a prototype system of the Integrated Data Safe Zone based on redesigned and optimized pseudonymization workflows. Conventional workflows of pseudonymization were redesigned by applying the amended guidelines and selectively revising existing guidelines for business process redesign. The proposed prototype has been shown quantitatively to outperform the conventional one: 6-fold increase in time efficiency, 1.28-fold in cost reduction, and 1.3-fold improvement in data quality.

In order to control the root-zone temperature of greenhouse crops in the hydroponics at hot and cold season, heat pump system for cooling and heating was built and tested in this work. The system was air-to-water type and vapour compression type. The heating and cooling mode was selected by the four way valve. Capacity of the compressor was 3.75㎾ and heat transfer area of the evaporator and the condenser were 3.05㎡ and 0.6㎡, respectively. According to the performance test, it could supply heat of 42,360 to 64,372kJ/h depending on the water circulation rate of 600 to 1,500ℓ/h, respectively, when indoor air temperature was 10∼20$\^{C}$. COP of heat pump system was 3.0 to 4.0 in the heating mode. But, COP of the cooling mode was 1.3 to 2.1 at indoor temperature of 20∼35$\^{C}$. The feasibility test in the greenhouse the developed heating and cooling system was installed, showed that the heating cost of the developed system was only about 13% of that of the conventional heating system. The heating cost of the developed system was 367won/day(electric consumption 9.7㎾h/day), while that of the conventional system was 2,803won/day(oil consumption 7.7ℓ/day) at the same heating mode.

This study is intended for the development of urgent facing strategies for the designation of a CFZ(Customs Free Zone) in Incheon city. First, it analyzes the current status of the Incheon CFZ. Next, it suggests several strategies for successfully growing the CFZ of Incheon City. Finally, it develops and proposes a method for establishing an integrated management system for the effective management of the CFZ. The key findings of this study are as follows: First, the CFZ should provide state-of-the-art movement of port logistics, create new added value caused by the movement of logistics, and provide other public support. The Incheon CFZ should be developed in three stages: an inducement stage in 2002-2005, a growth stage in 2005-2008, and an implementation stage in 2008-2011. Second, The parties responsible for the management of the CFZ would be as follows: for the port area, the Ministry of Maritime and Fisheries; for the back space of CFZ, Incheon City; and for port management, port management companies. However, a committee for CFZ management is strongly suggested for the improved efficiency and effectiveness of CFZ management. Furthermore, additional regulations ensuring the role of local government will likely be necessary for the sucessful designation and sustainable management of the CFZ. Third, For the creation of additional revenue, reformation of the current laws of the CFZ are recommended in the area of business administration. Fourth, A strategic marketing plan that supports the successful management of the companies of the CFZ will be a key component in the success of the CFZ. Thus, the new marketing plan should be developed in the near future based on case studies of other CFZs. Fifth A method for an integrated CFZ management system was developed and suggested for the comprehensive and transparent management of port logistics.

Based on the combined results of field surveys and analyses of the road structure and traffic flow, we propose a new plan for reducing roadside non-point pollution in the Paldang Water Source Protection Zone. The results show that the soil surrounding the roads in Paldang is highly permeable, which mitigates the need for filtration facilities. Roads flanked by steep slopes are found to facilitate the reduction of non-point roadside pollution through vegetation and soils along road slopes without the need for pollution reduction facilities. These results highlight the need for a flexible roadside non-point pollution reduction plan for roadside non-point pollution, which can be tailored to compliment relevant regulations and design standards after analyzing the characteristics of the target road.

Northeast Asia is increasingly making a transition to distinctive and crucial region in the 21st Century and growing into one of world's top three economic spheres along with the EU and NAFTA. In 2003, Korean government announced the Northeast Asian economic hub country plan as an important agenda. As a means of coping with the changing global environment, Korean government designated Incheon in 2003 as the country's first Free Economic Zone ahead of Busan and Gwangyang Bay in the south of the country because Incheon has a geographical advantage linking North America and Europe with Incheon International Airport and Incheon Seaport. The purpose of this paper is to make research on establishment and operation of an arbitral body entitled ${\ulcorner}International Arbitration Center{\lrcorner}$ (IAC) within Incheon Free Economic Zone(IFEZ). For the purpose of this, the writer in this paper, reviewed the necessity of the IAC's establishment and its legal basis as well as the role and function of the Center. Also, the writer presented plans for how to operate the IAC and how to cooperate with the key arbitral organizations of foreign countries for the settlement promotion of commercial disputes including trade and investment. With development of the IFEZ, world-renowned enterprises will invest in the Incheon economic bloc and conduct economic activities, business operation, marketing, logistics, financing, etc. In this connection, diverse types of commercial disputes are expected to occur between foreign companies entering the IFEZ and Korean firms. In this connection, the Korean Commercial Arbitration Board(KCAB) has been operating its liaison office in the IFEZ since 2004. However, in view of the increasing arbitration demand, the IAC should be set up in the IFEZ in the near future by the positive support of the government in the respect of both administration and finance because the free economic zone-related law provides for the installation of arbitration organization. For the success of the IAC, the Center will have to provide not only good quality of arbitral services that can satisfy arbitration parties but also need to conduct researches and make efforts so that arbitration can be utilized well in the IFEZ. If the IFEZ can provide advantageous business environments to those multinational enterprises intending to the Incheon economic bloc, the IAC will also contribute to the settlement of commercial disputes arising from the Gaeseong Industrial Complex in North Korea in view of the geographical advantage and logistic benefit of the IFEZ. Finally, this paper also suggests a new model for a joint dispute resolution system by the initiative of Korean government and Korean arbitral organizations for the settlement of commercial disputes within Northeast Asia, for which the CAMCA(Commercial Arbitration and Mediation Center for the Americas) of NAFTA can be a good example.

It is predicted that future climate warming will occur, and the subtropical climate zone currently confined to the south coast of Korea will gradually rise north. The shift of climate zone implies a change in area for cultivating crops. This study aimed to evaluate the current and future status of climate zones based on the high-resolution climate data of South Korea to prepare adaptation measures for cultivating crops under changing agricultural climate conditions. First, the climatic maps of South and North Korea were produced by using the high-resolution monthly maximum and minimum daily temperature and monthly cumulative precipitation produced during the past 30 years (1981-2010) covering South and North Korea. Then the climate zones of the Korean Peninsula were classified based on the Köppen climate classification. Second, the changes in climate zones were predicted by using the corrected monthly climate data of the Korean Peninsula (grid resolution 30-270m) based on the RCP8.5 scenario of the Korea Meteorological Administration. Köppen climate classification was applied based on the RCP8.5 scenario, the temperature and precipitation of the Korean Peninsula would continue to increase and the climate would become simpler. It was predicted that the temperate climate, appearing in the southern region of Korea, would be gradually expanded and the most of the Korean Peninsula, excluding some areas of Hamgkyeong and Pyeongan provinces in North Korea, would be classified as a temperate climate zone between 2071 and 2100. The subarctic climate would retreat to the north and the Korean Peninsula would become warmer and wetter in general.

With the recent advancement of 4th Industrial Revolution technology, transportation systems are generating large amounts of mobility data related to the individual movement trajectories of vehicles and people. There are many constraints on utilizing mobility data containing personal information. Thus, in South Korea, the processing and generation of pseudonymized information and the analysis and utilization of this information have been managed in a dual manner by applying separate agencies and technologies through the revision of the Data 3 Act and the enactment of the Data Basic Act. However, this dual approach fails to securely support the entire data lifecycle and suffers from inefficiencies in terms of processing time and cost. Therefore, to compensate for the problems of the existing Expert Data Combination System and Data Safety Zone, this study proposes an Integrated Data Safety Zone Framework that integrates and unifies the process of generating, processing, analyzing, and utilizing mobility data. The integrated process for data processing was redesigned, and common requirements and core technologies were derived. The result is an architecture for a next-generation Integrated Data Safety Zone system that can manage and utilize the entire life cycle of mobility data at one stop.

A long-range prediction system of tropical cyclone (TC) activity over the western North Pacific (WNP) has been operated in the National Typhoon Center of the Korea Meteorological Administration since 2012. The model forecasts the spatial distribution of TC tracks averaged over the period June~October. In this study, we separately developed TC prediction models for summer (June~August) and autumn (September~November) period based on the current operating system. To perform the three-month WNP TC activity prediction procedure readily, we modified the shell script calling in environmental variables automatically. The user can apply the model by changing these environmental variables of namelist parameter in consideration of their objective. The validations for the two seasons demonstrate the great performance of predictions showing high pattern correlations between hindcast and observed TC activity. In addition, we developed a post-processing script for deducing TC activity in the Korea emergency zone from final forecasting map and its skill is discussed.

The international marine system was plunged into the age of divided occupation with the adoption of the United Nations Convention on Law of the Sea in April, 1982. The exclusive economic zone of 200 Nautical miles set up by the Convention confirms the assertions of many coastal states whose fishing industries are not well-developed. However, it is unfavorable to the countries whose fisheries are being carried on in deep-sea, because the coastal state has sovereign rights to conserve and manage living resources in it. Under the circumstances the Korean deep-sea fisheries had to find ways out of the difficulties. The ways may be divided into two ways, namely, licensed fishing and joint-venture fishing. The former type becomes unfavorable to foveign fisheries because of decreasing quarts, rising fees and remunerations. The latter type properly meets the wishes of countries concerned and has some merits. However, there is a possibility of bearing the risk in case of investment in developing countries. The insurance system is effective to make up for the loss from the risk, although not perfect. The deep-sea fisheries depressed now by accumulated difficulties need more financial support from the Goverment for the active promotion of overseas joint-venture.

This research is to investigate the effect of the improvement of investment environments with investment incentive on Korean national economy by looking into the foreign investment support system in Korea. To this end, first research model was set up based on our literary study and case study was conducted on 150 foreign companies that were located in industrial complex for foreign companies, received the tax benefit and government subsidization. And it was found that even though the foreign companies were contributing to the national economy in general such as in the area of production, export, employment, development of technology, there was no significant contributory difference between the investment incentive beneficiary and non-beneficiary foreign companies. Therefore it deemed reasonable to reconsider the way Korean government supports foreign companies in Korea and to reinforce foreign companies' relevance to national policy agenda with additional incentives to foreign companies located in comparatively less developed areas. As a way to promote foreign investment, promotion of investment infra such as improvement of follow-up services, openness to foreign investment, industrial deregulations in capital area, revitalization of free economic zone, efficient system to promote foreign investment and the reinforcement of public relations were considered necessary, especially the upgrading of economic structure and the integrated management of domestic and foreign investors deemed necessary for the optimal distribution of the industries.
