It is important to understand the current status and problems of the North Korean shipping industry to prepare for inter-Korean trade in the future era of peace in the Korean Peninsula. In this study, the status of vessels calling in North and South ports was analyzed by year, cargo type (vessel type), and North Korean port type using Port-MIS data. In particular, considering the three years (2006-2008) in which inter-Korean trade was the most active, the flow of maritime transport was analyzed by visualizing data on vessels' arrival and departure in the North and South ports. Findings revealed that sea transportation between Haeju-Incheon was the most frequent, while the Haeju-Mokpo and Nampo-Incheon routes in the west coast area, and the Najin-Busan route in the east coast area were active. With reference to general cargo vessels, ports located on the west coast of Korea tended to operate between those located on the North coast of North Korea and on the east coast of South Korea. These results are expected to serve as a basis for establishing research and policies related to coastal shipping between the two Koreas in the future.

The Military Demarcation Line(MDL) divided the two Koreas when armistice agreement was signed in 1953, July 27 but there was no regulation for the sea border. Since then, The North has constantly denied the legitimacy of the sea border, which has remained the inter-Korean maritime border. But the armistice agreement has been virtual maritime demarcation line for the avoidance of hostilities on the Korean Peninsula and maintain and manage the armistice system peacefully. Therefore we should strengthen the Korea's sovereignty over the NLL by tightening the effective control.

The EPCglobal Network is a system which provides the information of items to suppliers, consumers, and customers by granting identification numbers on the goods based on the technologies of EPC(Electronic Product Code) and RFID(Radio Frequency Identification), and connecting the space to store those information by network. The EPCglobal architecture framework is also a service consolidating supply and process chain by using EPC for the common goal of business corporations. In the national level, it is necessary to define standard vocabularies for each location and logistics business process for RFID environment using the pre-constructed logistics information infrastructure. Therefore, we define the standard vocabularies and partially user vocabularies for international logistics on EPCglobal network architecture. Finally, we believe that our vocabularies contribute to describing the events fur the EPCglobal network architecture and actually providing usable platform via the XML implementation.

Environmental issues resulting from climate change and energy crises have become global issues, and cycling has gained greater popularity for sustainable transportation. Though many cities are trying to build bicycle roads, it is not easy to implement bicycle roads because there is little available space for bicycle facilities. Therefore, road diets have become more popular in Korea. However, there has been no intensive research to date of their impacts. The purpose of this research is to evaluate the effects of road diets and construction of bike lanes. Every benefit, including energy benefit, environmental benefit, and health benefit is considered, while only time savings benefit has been considered in previous studies. The benefit analysis for the Seoul metropolitan area as a case study shows that road diets have a (1) time saving benefit for only five percent of the mode share and (2) enough total benefit even if bicycle mode share is less than two percent.

Ubiquitous environments make it possible to connect people and objects together seamlessly using networking technology. To realize ubiquitous environments many kinds of devices should follow the exact protocol. To observe protocol and prepare the increasing network traffic are very difficult in the aspects of maintenance, so the new efficient technology is required. Wimedia technology is a prominent ubiquitous technology which can make connection with many devices. This paper propose a energy efficient method for Wimedia bridge implementation which is a part of scale-free uPAN systems. The proposed method can reduce network expenses which is generated by protocol requirements by adding efficient packet encapsulation and bridging technology. It can be proved to be more time and energy efficient by simulations.

This stud is my second trial to examine the costume of Balhae Dyansty. The subject of this study is the costume of a bronze statue excavated in the Maritime Provinces of Russia. The bronze statue is in the custody of Vladivostok Museum E.V. Shavkunov a Russian archelogist reported it a statue of-ficial of balhae dynasty in the 7-8th century. Judged his report lack of basis I suggest new opinion on sex, age, married or unmarried. social position manufactured time of the statue by comparative study on the costume hair-style and appearance of the statue with around nations' antiquities. hair-style of the statue is basically included in Ssangge and complexed style of Sage Ssangsuhuange, and Guange, Generally, Ssangge is a hair style of children, unmarried women, court ladies, dancing girls, and instrument player (lady)s'. The statue wears round-necked blouse long skirt broad fabric belt at high waist broad sleeve and confront collar coat cloud shaped shawl and risen tip shoes. The figure of statue is de-scribed plump. The statue shows straight sil-houette and high waist typical style of Tang, Uddai, The most characteristic facto is cloud shaped shawl Cloud shaped shawl was originally one of the northern race's shoulder ornaments. From the view of Comparative study the antiquities of NamDang and JunChock are simi-lar to this statue. Besides Tsukanovka river where the statue was excavated is Kraskino ruins of a castle formed single cultural layer of Balhae Dynasty and are relics of the layer of Balhae Dynasty and are relics of the latter period of Balhae Dynasty. Therefore this statue is assumed to have been manufactured at the last years of Balhae Dynasty and to be a figure of unmarried woman not official.

This study was performed to propose the developmental direction of the elderly suicide study by analyzing the trend of study in elderly suicide. A literature search was conducted using RISS, KISS, Nanet. A total of 184 research articles which were published on elderly suicide in Korea from 1996 to 2013 were analyzed with structured analysis forms. For statistical analysis, frequency and percentage were used with EXCEL program. As a results, a study on elderly suicide in the social welfare sector was actively and a survey of general elderly proportion of the study was high. In addition, most concepts of research were associated with suicidal ideation, depression, social support, and stress of the elderly. Therefore, existing in previous studies classified as high-risk elderly people living alone, poor elderly, a man who attempted suicide risk in elderly subjects research through a variety of research methods will be made.

The paper examines non-agricultural occupations of Korean immigrants in the Russian Far East from 1860s to 1930s. First of all, theoretical perspectives regarding immigrants\` job selection and positions in the labor market such as cultural theory, segmented labor market theory, human capital theory, and ethnic enclave theory were reviewed and then how these theories can be applied to various jobs of Korean immigrants including mining, fishing, small business, service, and miscellaneous jobs was studied. Next. this article points out that those theories cannot explain both supply and demand sides of migration simultaneously, suggesting the need to integrate two sides of migration. In order to fill out this gap in the literature, this paper suggests the integrative approach which combines supply side and demand side of migration. According to this model, several factors in the non-agricultural jabs which were affecting Korean immigration in the Russian Far East. were identified and discussed in relation with existing theoretical perspectives. Finally this paper concludes that, in order to understand Koran migration in the Russian Far East properly, we have to take into consideration simultaneously both supply-sided factors of immigration including farming-oriented characteristics of Koreans, Korean socio-economic problems preceding immigration, and self-dependent tendencies of Korean immigrants and demand-side factor like the Russian migration policy to the immigrants and various regional situations in the Russian Far East.

The rancidity of soybean (Glycine max L.) from Yeonhaeju, called "Bazaz", in powder forms was evaluated through a fluorescence spectrum test (FST). The results from the FST were validated by comparing the TBA and acid values. Soybean powders were stored in 25, and $90^{\circ}C$ for 20 days. The maximum excitation and maximum emission of fluorescent compounds generated from the soybean powder during storage were observed at the 360 nm and 430-440 nm wavelengths, respectively. The mean particle size of soybean powder was maintained at $40{\mu}m$ to avoid the dependence of the reaction area during measurement. According to the FST results, lipid oxidation did not actively progress during storage at $25^{\circ}C$. The fluorescence intensity (FI) from FST on the first day of storage was not significantly different from that on the last day of storage (day 20; p < 0.05), but the FI dramatically increased at $90^{\circ}C$. A smooth increase was observed in the initial stage; then, after 11 days of storage, the FI value increased by nearly 100% compared to that on the first day. The FI values were compared with TBA and acid values that were measured under the same storage conditions. All the values at $25^{\circ}C$ showed similar patterns during storage, but at $90^{\circ}C$, the FI and acid values showed similar patterns but the TBA decreased after reaching the maximum values on storage day 12. The results demonstrated that FST may be useful for measuring the rancidity of the powder form of soybean because it does not require extraction to measure the rancidity.

Since 2004, Asiatic Black Bear of the Jirisan National Park is subjected to the restoration project through the re-introduction by the Maritime Province of Siberia in Russia, North Korea, Northeastern part of China and Seoul Grand Park. The purpose of this study is to analyze diets with scat to identify Asiatic Black Bear's feeding habit and eating resources environment in the Jirisan National Park. 78 scats of Asiatic Black Bears were observed during the field studies of radio telemetry-marked bears and by chance in the Jrisan National Park, from 2005 to 2013. The relative frequency of occurrence demonstrated that the plants comprised the highest with 77%, followed by insects with 12.8%, mammals with 5.6%, birds with 0.5%, arthropoda with 0.5%, and others with 3.6%. Also, 52 scats among the collected scats that were measured for the ratio of food were subjected to dry weight, and plants were the highest with 91.2%, followed by mammals with 3.6%, insects with 1.0% and others with 4.2% in the order mentioned. Asiatic Black Bear's feed research demonstrated that the Asiatic Black Bear at Jirisan is omnivorous and that the vegetable food is the main feed instead of animal feed.
