Whereas previous researches on land policy after unification dealt with principally the problem of land confiscation under the communist reign, this research tried to propose a scheme of long-term land reform which was based on case studies on ex-socialist societies' experiences during their transformation, analysis on North Korea's institution related to land ownership and use. To reform North Korea's land ownership and use by the principle of market economy, North Korean should accumulate their commencing asset necessary for private ownership of land and housing. Therefore much focus should be put on the accumulation of the commencing asset at the early state of unification. On the extension of that line, the government of the Unified Korea should try to solve the problem of land confiscation by the communist party and land privatization in the region of North Korea. For the purpose, gradual land reform is more desirable than rapid one according to the case studies on ex-socialist societies. The government should avoid policies than can result in serious fiscal burden. Active participation of local government is highly recommendable in land tax and development. On the direction of land policy, this research proposed a four step long-term scheme of land reformation in North Korea. However, later researches should put more Korea. However, later researches should put more emphasis to the unification of land institution of North and South Korea which this research couldn't deal with sufficiently.

The purpose of this study is to present directions and programs for exchange and cooperation between libraries of South and North Korea. Specifically, it is to present the direction of exchange and cooperation programs in the library area and to present library exchange and cooperation programs that can be promoted in the [tight period], [reconciliation and cooperation period], and [South and North confederation period] through research methods of literature review, Focus Group Interviews (FGI), and expert advice. In this study, exchange and cooperation programs were divided into three projects that should be prepared by South Korean libraries, by direct exchange and cooperation between South and North Korean libraries, and by conducting with third countries or international organizations. Along with the conducting program periods, 8 major programs and 33 unit tasks were also proposed. Conclusions and suggestions suggested the need for sector-by-sector, step-by-step exchange and cooperation, establishment of systems to promote effective exchange and cooperation, establishing the formation of consensus within libraries, finding field-oriented agendas, and developing education programs of North Korea libraries for librarians.

The final aim of South Korean policies on North Korea and reunification of Korean peninsula is to reflect the direction and the form which South Korean authority has been pursuing. To achieve this aim, we must establish the forms of reunification and continue to prepare for contingency plans while focusing our effort to those policies. In pursuing peaceful reunification, the national security should not be neglected. Moreover, the policing policy is one of the important national security policies. In order to draw up more effective policing policies in a reunified state, this dissertation establishes some preparing measures on policing conditions and expected problems resultion from the reunification of Korean peninsula after studying similar problems in formerly divided countries. The chapter one shows the direction of reunification policy. The chapter two looks some policing problems in formerly divided countries The chapter three studys the expected policing conditions and preparing measures after the reunification of Korean peninsula The chapter four reposes some reasonal solutions for peaceful reunification.

The BeiDou is a satellite-based positioning and navigation system, which is under construction by the China Satellite Navigation Office. Until the June of 2014, the constellation of BeiDou navigation satellite system consists of 14 satellites including five geostationary earth orbit (GEO), five inclined geosynchronous earth orbit (IGSO) and four medium earth orbit (MEO). In this paper, we present the positioning results using BeiDou B1 code measurements obtained from three GNSS reference stations (BHAO, SKMA, MKPO). Combined Beidou/GPS positioning results are also compared to BeiDou and GPS only. BeiDou-only positioning errors for the east-west and north-south direction had less than 2 meter with root mean square (RMS) value. However, the positioning error for the up-down direction had larger than 10 meter at a 95% confidence level. Our results also suggest that the position precision is improved by combined BeiDou/GPS compared to BeiDou-only.

This study focuses on the fact that the past government has been consistent with the one-sided withdrawal policy without any clear countermeasures in relation to the ongoing nuclear development of the DPRK. The purpose of this study is to improve the understanding of South Korea's North Korea policy and to present the direction of the North Korea policy in the future by comparing and researching the North Korea policy pursued by Lee Myung - bak government / Park-Geun-Hye government. Such an attempt will provide a basis for evaluating the previous government's policies toward North Korea, and will also help to find alternatives to sustainable inter-Korean relations and North Korea policy to achieve a unified Korea.

The molecular cloud, embedding AFGL 2591, has a "head-and-tail" structure with a total mass of ${\sim}\;1800\;M_{\odot}$, about half of the mass (${\sim}\;900\;M_{\odot}$) in the head (size ${\sim}\;1.2\;pc$ in diameter), and another half in the envelope (${\sim}\;3.5\;pc$ in the east-west direction). We found a new cloud in the direction toward north-east from AFGL 2591 (projected distance ${\sim}\;2.4\;pc$), which is probably associated with the AFGL 2591 cloud. The $^{12}CO$ spectrum clearly shows a blue-shifted high-velocity wing at around the velocity $-20\;{\sim}\;-10\;km\;s^{-1}$, but it is not clear whether this high-velocity component has a bipolar nature in our observations. The observed CN spectra also show blue-shifted wing component but the existence of the red-shifted component is not clear, either. In some CN and HCN spectra, the highvelocity components appear as a different velocity component, not a broad line-wing component. The dense cores, traced by CN and HCN, exist in the 'head' of the AFGL 2591 cloud with an elongated morphology roughly in the north-south direction with a size of about 0.5 pc. The abundance ratio between CN and HCN is found to be about 2 - 3 within the observed region, which may suggest a possibility that this core is being affected by the embedded YSOs or by possible shocks from outside.

This study was performed to evaluate the spatial distribution of heavy metals using principal component analysis and Ordinary Kriging technique in the Gangwon Mine site. In the soils from the sub soil, the contents of Zn and Ni in the PC1 were gradually dispersed from south to north direction, while the components of Cd and Hg in the PC2 showed an increase significantly from middle-south area in the Gangwon Mine site. According to the cluster analysis, pollutant metals of As and Cu were presented a strong spatial autocorrelation structure in cluster D. The concentration of As was 0.83mg/kg and shown to increase from the south to north direction. The spatial distribution maps of the soil components using geostatistical method might be important in future soil remediation studies and help decision-makers assess the potential health risk affects of the abandoned mining sites.

This study aimed to narrate the feature of a north korean refugee child at an elementary school in south korea through badminton sports cub activity. The narrative was as follows. Dongsik was unhappy at the first time in living here(south korea). After a while he had encountered badminton activity by chance. And he changed his life at the school and he has his own dream now. Teacher choi has remembered the first meeting with Dongsik. Dongsik was a boy who did not talk with anyone. After a long time Dongsik spent his life without uttering a word. Now he has a talk about his dream due to badminton. He dreams of being a badminton player. What is primarily important for north korean refugee children is educational direction. School eduction has to integrate not segregate to participate in all program together. We all have to take both expectation and confidence for north korean refugee children.

Annual variations In main fishing grounds of common squid with different angling and their fishing conditions in Korean waters were studied by analyzing catch and water temperature data. The main fishing grounds of squid angling fishery started to moved to the north in April and to the south in September in the last Sea of Korea. The catch of squid was related to the direction of thermal fronts. The catch was high when the thermal front was formed in the east-west direction, while there was low catch when the thermal front was formed in the south-north direction which runs parallel to the roast.

This study surveyed the actual status of reclamation areas in South Pyongan Province, North Korea, using satellite images and literature to survey the creation date, area, and length of the embankment of the reclamation areas. The reclamation areas in South Pyongan Province were created in three stages, with the first stage completed in the late 1970s or early 1980s, the second stage in the late 1980s or early 1990s, and the third stage in the 2000s. The total area of the reclamation areas is 105,570 hectares. The land cover of the reclamation areas is as follows: agriculture (50.5%), saltern (29.5%), water bodies (13.6%), foreshore (12.4%), grasslands (3.0%), bare land (0.4%), facility (0.1%), and forests (0.1%). The study also found that the NDVI values of the reclamation areas vary depending on the location. The NDVI values of the Gwiseong and Namyang reclamation areas are low, while the NDVI values of the Samcheonpo and Jigdongbaedali reclamation areas are high. The study found that the NDVI values of the reclamation areas are correlated with the land cover of the reclamation areas. The study's findings can be used to understand the development direction and regional characteristics of the reclamation areas in South Pyongan Province. The study's findings can also be used to develop policies and plans for the sustainable development and utilization of the reclamation areas in South Pyongan Province.
