CSD is Active RFID based Container Security Device which is proposed by the U.S Department of Home Security. It is mounted inside the container to sense opening of the container door. ConTracer is the CSD which is developed in this research whose major features are sensing door opening status as well as history inquiring on internal environment and shock to the container by mounting the temperature/humidity/shock sensors. Moreover, its RFID frequency bandwidth uses 433MHz and 2.4GHz to correspond actively to the radio regulations used by different countries. This paper introduces the development trend of CSD, compares the ConTracer which is developed thru this research and other company's CSD, and introduces CSD System which is designed and established using ConTracer. Finally, the implemented CSD System is verified by applying the demonstration service to container distribution between Korea and China.

The advent of multi-cultural society and multiracial nation is a new change of the times and a new phenomenon. In this social change, a need for a new theory and a new policy appropriate for Korean conditions is surfacing. In case of Japan, they have been changed into stable multi-cultural society by establishing various policies. An investigation on the changing process of policy in Japan has a great significance, we think. This study compared and analyzed the reason of promoting multi-cultural policies, changes of the related laws and institutions and the policies between Korea and Japan, investigated characteristics and differences between them, deduced implications and presented a new theory for multi-cultural policy appropriate for Korean conditions. In order to establish a new multi-cultural policy in Korea, firstly, acceptance of diversity and mutual recognition, secondly, establishment of policy direction through social consultation and thirdly, establishment of multi-cultural regulations followed by reestablishment of economical and political regulations should be required.

This is the first study of the relation between the controversy on Korean Economics and the controversy on the capitalist social formation of Korea in the 1970-80. The main results of this study is as following: Almost all Korean Economists think 'Korean Economics' do not exist, but korean philosophers think Korean philosophy which is different from western philosophy do exist. So Korean economists tend to believe in the universal validity of western economics. In fact, Some Korean Economists began to argued about universal validity of American-Western economics and making Korean Economics in 1970s, the controversy ceased in the mid of 1980s. Left-wing Economists insisted that the right wing conservetive economics is imported from, mainly, U.S.A, Korea is academic colony of U.S.A. But progressive economics was also imported from Western world, or Soviet Union in the process of controvesy on Korean capitalist social formation in 1980s. It is necessary to retrospect and re-examine the controversy on Korean Economics and on Korean capitalist social formation to develop Economics of Korea.

South Korea's economic growth was rapid, It was occasioned the concentration of resources in the metropolitan area. On the other hand, the province has a narrow economic base compared to the metropolitan area, and the underpopulation have been identified. Thus, The government announced the 'National balanced development law' in 2004 to reduce the problem of regional imbalances. The study collected data on 95 of relocated public institutions, and unlike previous studies, Mamquist analysis was used to compare the productivity before and after each public institutions' s relocation. The study focused on how the relocation of public institutions affected the productivity of public institutions through Malmquist Analysis. The results of the analysis show that productivity is declining after most public institutions have moved. And two independent samples T-test result, respective yearly average is nonsignificant.

The purpose of this study is to identify and evaluate the competitiveness of ports in ASEAN(Association of Southeast Asian Nations), which plays a leading role in basing the hub of international logistics strategies as a countermeasure in changes of international logistics environments. This region represents most severe competition among Mega hub ports in the world in terms of container cargo throughput at the onset of the 21 st century. The research method in this study accounted for overlapping between attributes, and introduced the HFP method that can perform mathematical operations. The scope of this study was strictly confined to the ports of ASEAN. which cover the top 100 of 350 container ports that were presented in Containerization International Yearbook 2002 with reference to container throughput. The results of this study show Singapore in the number one position. Even compared with major ports in Korea (after getting comparative ratings and applying the same data and evaluation structure), the number one position still goes to Singapore and then Busan(2) and Manila(2), followed by Port Klang(4), Tanjugn Priok(5), Tanjung Perak(6), Bangkok(7), Inchon(8), Laem Chabang(9) and Penang(9). In terms of the main contributions of this study, it is the first empirical study to apply the combined attributes of detailed and representative attributes into the advanced HFP model which was enhanced by the KJ method to evaluate the port competitiveness in ASEAN. Up-to-now, none have comprehensively conducted researches with sophisticated port methodology that has discussed a variety of changes in port development and terminal transfers of major shipping lines. Moreover, through the comparative evaluation between major ports in Korea and ASEAN, the presentation of comparative competitiveness for Korea ports is a great achievement in this study. In order to reinforce this study, it needs further compensative research, including cost factors which could not be applied to modeling the subject ports by lack of consistently qualified in ASEAN.

Recently, it is more important to study the reasons for using media than which media is selected. This paper investigates different countries as objects to conduct the survey. In accordance with the research results, in hypothesis 1, there is a positive "(+)" influence of its interestingness, informality, restlessness, news pursuit and convenience on satisfaction when college students in South Korea use net news. Taking Chinese college students as an example, there is a positive "(+)" influence of the using motivation of net news on news pursuit, habituation, interactivity, convenience and the satisfaction with net news. In hypothesis 2, the interestingness, informality, habituation and convenience of the using motivation of online news of college students in South Korea are reflected in the acceptance intention of online news, while for Chinese college students, the informality, habituation and convenience are reflected in the acceptance intention of online news. Finally, in hypothesis 3, there is a positive "(+)" influence of the satisfaction of online news on the acceptance level of online news. In addition, this research also considers that the PLS path coefficient of college students in South Korea and China is different, and the motivations and purposes for using net news by two countries are different due to the characteristics and cultures of news media in different countries, so the satisfaction is also different.

Virtual water is defined as the volume of water to produce commodities and provide services, which has been developed by Tony Allan since the early 1990s. This research aims to evaluate a volume of virtual water trade in Korea from 1998 to 2007 by applying the evaluation method of unit virtual water volume to agricultural, live stock and industrial products, which is developed by Chapagain and Hoekstra (2004). Also, the concept of water footprint is deployed to quantify the volume of virtual water trade between countries. The study attempts to assess the appropriateness of the evaluation method of unit virtual water volume by employing the method to calculate the total amount of agricultural products in Korea and comparing this with the amount of agricultural water demand in the Korea Water Vision 2006. The research outcome shows that Korea has a net virtual water import of 32 billion $m^3$ on average in the form of agricultural, live stock and industrial commodities whose volume gradually increases. The gap between the volume of virtual water import of agricultural and live stock commodities and the total volume of agricultural water use reaches approximately 600 million $m^3$. This figure can be negligible considering the total volume of water demand in Korea, around 16 billion $m^3$, which demonstrates the validity of the evaluation method in terms of analyzing water balance.

Social changes due to ICT like Big Data, IoT, Cloud and Mobile is progressing rapidly. Now, we get out of the old-fashioned frame was measured at the level of the information society through the introduction of PC, Internet speed and Internet subscribers etc and there is a need for a new type of diagnostic information society framework. This study is the study for the framework established to diagnose and measure post-information society. The framework and indicators were chosen in accordance with the technological society coevolution theory and information society-related indicators presented from authoritative international organizations. Empirical results utilizing the indicators and framework developed in this study were as follows: First, the three sectors, six clusters (items), 25 nodes (indicators) that make up the information society showed that all strongly connected. Second, it was diagnosed as information society development (50.34%), technology-based expansion (25.03%) and ICT effect (24.63%) through a network analysis (ANP) for the measurement of importance of the information society. Third, the result of calculating the relative importance of the cluster and nodes showed us (1)social development potential (26.04%), (2)competitiveness (15.9%), (3)ICT literacy (15.5%) (4) (social)capital (24.3 %), (5)ICT acceptance(9.54%), (6)quality of life(8.7%). Consequently, We should take into account the effect of the economy and quality of life beyond ICT infrastructure-centric when we measure the post-information society. By applying the weighting we should performs a comparison between countries and we should diagnose the level of Korea and provide policy implications for the preparation of post-information society.

This study analyzes universities in Japan, which haves many similarities with those in Korea in certain aspects of the educational system and a common problem of reduced university admission resources, Korea's national university facility standards, policy related to nation-level university facility, and practical campus case. Through this, the study aims to examine the difference in the national approach and basic philosophy about university facilities in Korea and Japan, and also identify the major planning factors and improvement directions when establishing plans for university campuses in the future. The results of this study are as follows. First, Korea tends to promote policies related to university facilities by individual projects centered on a major pending problem or issue, while Japan has been shown to promote national university facility policies under a comprehensive mid-to-long-term plan by establishing a maintenance plan aimed at national university facilities every five years. Second, In the case of the university facility areas, the average university facility area of the examined universities in Japan is about 5.6% larger than the average university facility area in Korea. Additionally, the university facility area per student in Japan is about 13% wider than that of Korea. The total floor area of university facilities in Japan is also about 20.7% larger than that of Korea, and the university facility area per student in Japan is about 56.7% wider than that of Korea as well. Among support facilities, the total floor area of dormitories in Korea was 2.5 times wider than that of Japan, however, the acceptance rate of dormitory in Korea was 5.6% higher than Japan. Third, the university facility criteria items and systems of two countries are similar. but there are slight differences in the content such as the method of calculating student capacity, division classification, and the method of calculating the number of teachers.

The purpose of this research is to understand the view on people(百姓) and Lee Won-ik(李元翼)'s view on politics, comparing with Seonjo(宣祖)'s view on them. They as political actors sufficiently cognized the condition of life of people had been very desperate. Seonjo had approached from politics to the life of people, while Lee from the life of people to politics. The former has the precariousness of transformation and instrumentalisation of the life of people. The latter has the possibility of the life of people to lead the politics. Lee's stance was on the latter aspect. He had tried to conceive the people as they are, in other words as reality, not as they should be, in other words as idea. He refrained the elucidation of people from confining it within dichotomy structure of ruling-ruled. He had tried to conceive the organic relationship between people and other existences within community. He did not give knowledge-centered question of what is the life of people, but gave situation-phenomenon-centered question of how people has been living. This approach eulciates Lee's focus on the problems of Gongyi(工役), military service(軍役), Labour service(?役), the reduction and exemption of the tax, and the appointment of provincial officer(守令). As for Lee Won-ik, the best form of life of people is to make people have mind to deserve to live, to economize their power(寬民力), to make them savor their life(樂民生), and to make their life easy(安民).
