In the Republic of Korea, punishment of conscientious objectors is rising as a social issue once again. Large number of news articles on the punishment of conscientious objectors are updated on portal sites several times a day. The background for this phenomena is based on the disagreement between the Supreme Court and the Constitutional Court. The Constitutional Court has ruled that it is constitutional for the government to punish conscientious objectors who denied their service for religious belief according to the Clause 1 of the Article 88 of the Military Service Law. However, district courts have taken different stance in the lower instance. 6 rulings in 2015, 7 rulings in 2016, and 16 rulings in the first half of 2017 has declared the conscientious objectors as not guilty. At the same time, the issue is becoming more controversial as the Jeju District Court has made two different rulings on the punishment of conscientious objectors who denied their military service for religious belief. Therefore, the study aims to find out whether conscientious objection can be included as a reasonable cause under the Clause 1 of the Article 88 of the Military Service Law, and take thorough review on the interpretation and the application of Article 18 of the Human Rights Covenant by examining the rulings at the Supreme Court, Constitutional Court, and District Courts.

As coastal erosion is increasing sharply because of sudden changes in the natural environment and increases in artificial development, the problem of coastal erosion become an important issue, socially and economically. To building the data which needed to grasp the situation and find a solution, we need the monitoring system for long-term. In this study, we analyzed the coastal topography and land cover changes in the Haeundae Beach during 60 years. The Haeundae Beach is the most famous beach in the country and coastal erosion are going on. First, we analyzed the change of coastal topography by calculated the coastline and area of the beach using aerial photos during 60 years. We extracted the coastline by digitized on aerial photo and corrected the height of tide level using sounding and GPS survey data. And we computed the area of beach and analyzed the change of area during 60 years. Second, we analyzed the change of land cover using landcover map. We made the detailed landcover map by on-screen digitizing and estimated the soil loss for the area nearby Haeundae Beach. As a result, we could see that the coastline get nearer to land and the area of beach has been reduced in general. We think that interception of sand supply by the development is the artificial cause of coastal erosion. The result of this study would be useful in long-term coastal monitoring and to analyze the cause of coastal environment change. We expect that the result is available on the coastal information system.

A parallel importation is a non-counterfeit product imported from another country without the permission of the intellectual property owner. It is caused by price differences between countries. Therefore parallel importation are implication in issues of international trade and intellectual property rights(hereafter referred as IPR). This paper provides parallel importation issues of Korea and China under the IPR laws such as patent, trademarks, copyright and analyzes difference between two countries. In China, patent law regulates exhaustion rights which is based theory of a parallel import for the first time unlike trademark law and copyright law. On the other hands, Korea rules parallel importing under Korean customs regulations. In conclusion, two countries have no provisions that advocate a parallel import under IPR laws. This paper suggests some improvements to overcome the limitation of current regulation system and avoid trade friction between two countries. First of all, two countries should clearly make a rule about parallel import in IPR law such as definition of parallel importation, genuine goods, permission conditions, importing proses, penalty and remedy etc. Secondly, two countries should prohibit an abuse of a exclusive import agent's rights and manage a parallel importer not to cause consumer's complain about goods to expansion parallel imports. Finally, two countries should cooperate not to cause disputes about this issue with a communication channel.

Correcting an imbalance between cognitive and affective aspects of mathematics in schools is recognized as a crucial issue with regards to mathematics education in Korea. Therefore, research and studies about affective aspects have been increasing and themes relating to affective aspects were diverse. Their theme included the improvement of affective aspect, investigation of factors of affective aspect, and development of measurement tools for affective aspect. The purpose of this study is to analyze and organize the research that has been done with respect to affective aspect and drive trend, implication, and their instruction to mathematics education. This study has investigated 103 studies released from 2005 to 2015 on KCI, Korea Citation Index. The results of this study are as follow. First, since released research of affective aspects in mathematics has not increased in number in the last 11 years, academic interest in the affective aspects seems lower than recent interest arousing in Korea. Second, most studies utilized quantitative research as a tool to analyze phenomena and the cause and effect of affective aspects. Third, middle school students were the most common subjects of the studies, followed by elementary school students. Fourth, the studies had various themes such as analyzing the cause and effect of affective aspect, recognizing changes of affective aspects, and measuring affective aspects. The studies, especially, focused most on analyzing how to improve affective aspects by applying it to programs such as mathematic activities and solving mathematic problems. It is necessary for future research to have a long-term perspective and to provide a space for communication. Research should not only focus on how recognize affective aspects differently, which is based on its cultural background, but also to draw affective solutions from them.

The digital signal is terminated on Dec.31, 2012. But most of the analog cable subscribers are faced with the difficult reception of the digital because the government has defined the terrestrial broadcast as digital transition obligation operators. It is estimated that half analog of the total pay-TV subscriber that is approximately 10million households that are directly receiving terrestrial signal must hold the digital TV or DtoA convertor to transit digital. But cable system subscriber should buy Set-top box that are expensive and pay the expensive rates. The cast of analog cable subscribers has been classified as a group that can cause the most damage after digital switch. This study investigate the problem, and cause, solution of the analog cable subscribers that are placed in the blind spots of the digital switch.

This study began with the fact that the relationship between eductional environments and housing price needs to be understood in the context of the structuring of socio-spatial disparity. In other words, this paper focuses on the fact that the eduction with public features and functions plays a role of housing price determination and the rising price is privatized only to cause socio-spatial inequality. The study first examines how the education factors determine the housing price and cause increasing social inequality in Seoul at the macro level. It also carried out more detailed quantitative analysis on the relationship between educational environment factors and housing price with the case study of Yangcheon-gu, Seoul. This study found out that the close relationship between educational environment, housing price and social disparity at various spatial scales. It also figured out the the educational environment factors play an important role of housing price determination as much as material features per se. This means that the relationship between education, housing price and inequality needs to be dealt with not just socially but also in spatial perspective. In addition, the housing price determination is not just technical research but an social science issue in the context of rising socio-spatial disparity. This study is of only significance as a starting point of promising related researches in the future and much more efforts will be needed.

Rice yield of South Korea in 2015 was the highest of the last 30 years. It is important issue to establish food policy whether the historically highest yield in 2015 can be continued or just one-off event. Therefore, it is necessary to understand whether such a high yield as 2015 will be reoccurred. The aim of this study was to find out what climatic factor affect rice yield and how often these climatic factor could occur. For this study, the yield monitoring data from National Institute of Crop Science, Rural Development Administration and the meteorological data provided by Korea Meteorological Administration are used to identify the weather conditions could cause high yield, and how often these conditions occurred in the past. Our results indicated that such as high yield as 2015 could occur only when the mean sunshine hours of July and the mean sunshine hours from the end of August to early September was more than 5.1 hours and 6 hours, respectively. Mean sunshine hour of July may be related to grain number. The mean sunshine hour from the end of August to early September was presumed to relate to grain filling ratio. The relationship between monthly mean temperature and yield or yield component was not clear in this study. In this study, any cycle of high weather condition was not found. Therefore, the probability of high yield weather condition was expressed by frequency. The frequency of the sunshine hour, could make high yield, were 8/35 (23%) over the past 35 years. And the frequency of two years consecutive sunshine hour condition, which could cause high yield, was 1/35 (2.9%). The frequency of recurrence of sunshine hour making high yield within the next 5 years or 10 years after high yield weather condition were 4/35 (11.4%). After all, the high yield as much as yield of 2015 could not be one-off event. But it was not also consecutive event.

Objectives : In present, various definitions of Zhongshu are being used interchangeably in Korea. The paper attempted to discover the disease of Zhongshu as studied by Lidongyuan, who was ahead of his time. Methods : A database of medical books has been studied to find Lidongyuan's writings on the disease of Zhongshu, and mentions about Li's works in past medical books. The paper contemplated the subject by defining the disease of Zhongshu and reviewing the disputes related to the subject. Results & Conclusions : Lidongyuan gave a detailed explanation on the fact that Zhangjiegu distinguished between Zhongshu and Zhongre, and this was influenced by Shangshu as mentioned in Taipinghuiminhejijufang. Therefore, it can be deduced that he was aware of the fact that summerheat-heat as latent summer heat syndrome is lurking inside the body, not being able to be released. According to the disease of Zhongshu by Lidongyuan, yin cold was receieved secondary after first receiving summerheat-heat. It is either summerheat damaged defensive qi, failure in storing the essence made defensive qi weak, or seasonal reasons have caused the defensive qi to be drained and leave the body exposed to damage by summerheat. This is because the fundamental main cause is the hitting of summerheat, since yin cold was received after the presence of summerheat-heat is made first. Many doctors in the following generation criticized that Lidongyuan's disease of Zhongshu cannot be named as a Zhongshu due to its similarity with Shanghan. However, they cannot be viewed as similar since it is a phenomenon where yin cold becomes congested while the body is weak and heat is generated in the body due to summerheat-heat. The doctors who said they were similar only focused on the external cause that was only the superficial issue. According to Lidongyuan's method, the right way to treat a Zhongshu disease is to use the method of tonifying the qi and eliminating the heat in conjunction with eliminating the internal dampness or treat the external syndrome, or to use a formula to tonify the qi and eliminate the fire heat before eliminating the internal dampness or treating the external syndrome.

Purpose - After Korea's Free Economic Zone (FEZ) system was launched in 2003, there have been many debates about upgrading it and its support systems. However, as of 2013, there were insufficient results. Further, upon the designation of the East Coast and Chungbuk as official FEZs from February 4, 2013 by the 56th the Commission, there is a concern that many people are in the area designated as FEZ 8. This study investigates Korea's new FEZ system as part of Korea's primary new economic development policy in the 21st century. Therefore, this study examines views on the weaknesses of the past ten years of FEZs so that Korea can expand its FEZ system. Research design, data, and methodology -Many countries have considered the FEZ as an economic special zone. By reviewing previous research models, this study provides an update using recent data and materials, until 2013, from the Center of Free Economic Zones. In previous studies, the lack of support systems was attributed to proposals to ensure operational autonomy and differentiation of each FEZ; however, the main cause cannot be solved through regulatory issues, as difficulties caused by the operational system are responsible for the problems. We wish to analyze the FEZ, specifically the operational system; this is the main issue of this study. Results - After the first FEZs were established, it became necessary to have basic plans, as investment results in 2013 compared to the same period this year led to lower earnings in the first half of 2014. We propose an improvement of the operational system because in the free economic zones, the operational system is the root cause of the underlying problem. The results of this research are as follows. The weak management of the FEZ system is influenced by weak investment, delayed development, foreigners' living facilities, benefits of foreign investments, the control tower's policy making decision process, quickness of the process of satisfying legal requirements, and support For the independence of FEZs. Conclusion - Local governments do not have legal rights over FEZ deregulation and investment industries. This study suggests that the local government should have more independence from the central government. Moreover, independent management committees are more effective for ensuring public rights, better employee responsibilities, and better-qualified personnel. The FEZ committee struggles to effectively manage the locations of FEZs, foreign investments, and related facilities under the control of the Ministry of Trade, Industry and Energy. Thus, the FEZ committee should be under either the Prime Minister's office or the Presidential committee, to control and effectively coordinate between the local and central governments. If the problem clearly applies to the operational system in 2013, it is necessary to provide materials and methods so that the results of the first half of 2014 can be computed despite the data limits and lack of resources, and the data can be analyzed in a more diachronic thesis.

In a big data platform, association rule mining applications could bring some benefits. For instance, in a agricultural big data platform, the association rule mining application could recommend specific products for farmers to grow, which could increase income. The key process of the association rule mining is the frequent itemsets mining, which finds sets of products accompanying together frequently. Former researches about this issue, e.g. Apriori, are not satisfying enough because huge possible sets can cause memory to be overloaded. In order to deal with it, SON algorithm has been proposed, which divides the considered set into many smaller ones and handles them sequently. But in a single machine, SON algorithm cause heavy time consuming. In this paper, we present a method to find association rules in our Hadoop based big data platform, by parallelling SON algorithm. The entire process of association rule mining including pre-processing, SON algorithm based frequent itemset mining, and association rule finding is implemented on Hadoop based big data platform. Through the experiment with real dataset, it is conformed that the proposed method outperforms a brute force method.
