In this study, it is purpose that value-added-logistics strategy plan for cooperation and coexistence in northeast asia.. Because of the change of domestic industrial structure, Japan's super hub port plan, Yangshan Deepwater port open of china and domestic port logistics industries are faced with competition among northeast asia countries. Decreasing export volume of changed domestic industrial structure and two countries: japan, china, make a new port policy and build new ports will affect domestic port logistics industries because these industries depend on container throughput at Busan port. Now, we cannot get a lot of profit from container throughput more than before and in the future China has more ports most ships direct calling in china's port to handle china's cargo volume to get more profit at that time our plans to become a hub port in northeast need revision. Finally, we need a new strategy which is value-added-logistics strategy. But it considers cooperation and coexistence among northeast countries. So this paper suggests that value-added-logistics strategy plan for cooperation and coexistence to live in affluence together in the future.

This experiment was carried out to investigate watering with relation to growth, quality and yield of essential oil in sweet basil. The degree of water stress was taken as amount of watering. D1 was watered with 25mL for 2 weeks and 30mL from 4 to 5 weeks after planting in Wagner pot (1/20000a, ${\phi}24cm$). As this, 75mL and 90mL, 225mL and 270mL, and 675mL and 810mL were watered in D2, D3, and D4 treatment respectively. DFT was set up as water stress was not inflicted. The growth of basil in D3 and D4 was better than that of others, in which root activity was as much twice as that of D1. Essential oil of D1 was recorded the lowest content as 0.33%. The result of proline content, peroxidase activity, photosynthesis, stomatal conductance and stomatal resistance were proved D1 to be stressed. This treatment consequently increased the content of essential oil. In consideration of growth and essential oil content, D3 treatment was highest as 47.37mg in oil production per plant. Finally, D3 watered with 225mL for 2 weeks and 275mL from 4 to 5 weeks after planting could be selected on the purpose of both plant growth and essential oil production. Essential oil content of sweet basil was increased in response to water stress. For increase of essential oil yield, oil synthesis could be raised by giving water stress just before harvesting.

This study was carried out to investigate the effect of a beverage that contained Bulnesia sarmienti(BSP, 2.5%) on rats to which alcohol was administered. The treatment of the BSP group reduced the serum alcohol concentration to 52%, compared to 47% in the positive control(PC) group. Similar pattell1s were observed in the enhancement of alcohol dehydrogenase(ADH), acetaldehyde dehydrogenase(ALDH), alkaline phosphate(ALP), alanine aminotransferase(ALT), asparate aminotransferase(AST), total cholesterol(CHOL), ${\gamma}$-glutamyltrasferase(GGT), glucose(GLU), total bilirubin, and total protein(TP) in the serum. Also, in the BSP group, the lipoxidase(LPO), glutathion-S-transferase(GST), XO, catalase(CAT), and superoxide dismutase(SOD) were significantly reduced, compared to the CO and PC groups in the liver. The glutathione(GSH) activity increased in the BSP group, though. These results indicate that Bulnesia sarmienti extract can enhance alcohol metabolization activity.

The port industry is an important national industry which significantly affects Korea's imports and exports which are centered on economic structure. For instance, the Port of Busan, which handles 75% of domestic container freight volume, is expected to become increasingly critical for container liner routes. For this reason, there have been continued efforts to expand freight service to attract international freight volume. This study analyzes the structural characteristics of the port network connected to the Port of Busan by analyzing the pattern of the container liner route from 2012 to 2016 by using social network analysis. According to the Port of Busan's liner route network, the port with the highest degree of centrality, closeness centrality, and betweenness centrality was found to be the Port of Singapore. The comparison of Busan's annual container handling rank by countries and the port center network analysis of Port of Busan rank was found to be different. As a result, it was established that China's East Port, which occupies a high percentage of the volume of cargo handled by Port of Busan, is not a hub port of Busan when viewed on the Busan's container terminal liner network. In addition, even if the number of Port of Busan container liner service increases, it is estimated that the vessels to be added to the fleet will be limited to small to medium sized, or that Busan port has characteristic of a feeder port for the Port of Singapore, according to the network.

In the process of adapting climate change, the government needs to provide policy and technical support necessary for growing promising crops imported from abroad. Therefore, this study was conducted to survey and analyze the conditions of growth of imported foreign crops and to derive response tasks. As a result, tropical and subtropical vegetables were cultivated 18 crops in 920 farms in 321 ha area (in 2015 year). The cultivation scale decreased in the order of Curcuma aromatica, Momordica charantia, Asparagus aethiopicus, Allium hookeri and Herbs. Tropical and subtropical fruits were cultivated 9 crops in 264 farms in 106.5 ha area (in 2015 year). Special and medicinal crops introduced abroad cultivated 10 crops in 753 farms in 276.3 ha area (in 2015 year). The cultivation scale decreased in the order of Curcuma longa, Glycyrrhiza uralensis, Lepidium meyenii and Moringa oleifera. For the stable settlement of domestic growth of tropical and subtropical crops introduced abroad, there should be safety and economic feasibility in terms of the cultivation environment according to the domestic culture adaptation test. Consideration needs to be given to the use of locally grown products in Korea, the securing of distribution and sales markets, and the competitiveness of imported products.

The growth of mobile devices in Internet of Things (IoT) leads to a number of intelligent buildings related IoT applications. For instance, home automation controlling system uses client system such web apps on smartphone or web service to access the home server by sending control commands. The home server receives the command, then controls for instance the light system. The gateway based RESTful technology responsible for handling clients' requests attests an internet latency in case a large number of clients' requests submit toward the gateway increases. In this paper, we propose the design tasks of the IoT gateway for handling concurrency events. In the procedure of designing tasks, concurrency is best understood by employing multiple levels of abstraction. The way that is eminently to accomplish concurrency is to build an object-oriented environment with support for messages passing between concurrent objects. We also investigate the performance of event-driven architecture for building IoT gateway using node.js on one side and communication protocol based message-oriented middleware known as XMPP to handle communications of intelligent building control devices connected to the gateway through a centralized hub. The Node.JS is 40% faster than the traditional web server side features thread-based approach. The use of Node.js server-side handles a large number of clients' requests, then therefore, reduces delay in performing predefined actions automatically in intelligent building IoT environment.

To ensure that Korea continues to grow, past governments have been consistent in following a policy of advancing into Russia, Mongolia, and Eurasia. The northern economy can expect to achieve synergistic growth because its economic structure complements that of Korea, which has high energy demand and industrial development. There is also an opportunity to accelerate the growth of the China-Russia-Mongolia economic corridor, which is based on Russia's Look East Policy, China's One Belt One Road, and the Mongolian Steppe Road initiative. The Korean government is pursuing a New Northern Policy to achieve the goal of economic cooperation and peace building with other nations, including North Korea; this policy succeeds the Northern Policy pursued by the previous government. As international economic cooperation requires transportation infrastructure, the demand for shipping, which offers more advantages than road and rail transportation, will increase; thus, it is necessary to prepare for it. Korea's port cities, which have a port that serves as the nodal point for maritime transportation, need to prepare for the New Northern Policy. In this paper, the long-term development of Seosan-Daesan port in the was planned and the North Korea's opening-op plan was considered in accordance with the New Northern Policy. Because international cooperation between the government and the provincial cities is required, cooperation with the Port Authority is needed, along with the proactive attitude of Seosan City, Chungcheongnam-do. The Seosan-Daesan port, which is the center of the liquid energy cargo center, can become the base of the New Northern Policy Region; further, the port can be an opportunity to establish its position as a peaceful economic hub on the west coast of Korea.

Adoption of applicable law for the international trade of artworks is closely related to the results of lawsuits. Recently, starting with New York, the hub of the international artworks market, a modern, mixed-law is gradually being adopted more. It is difficult to designate an applicable law of an international trade of artworks through private laws regulations of relevant countries, and the public laws regulations must also be considered in relation to individual benefits and the public benefits to the relevant countries. With regards to the foreign relations issues, Korea's private international law embraces a so-called public order theory, and according to the Section 7 of the Act on the Private International Law and its enactment history, the compulsory provision, which seems appropriate for application to the corresponding matter, applies without regards to the selection of the applicable law. The Civil Act of Korea acknowledges bona fide acquisition of a cultural asset, in principle, if the Cultural Heritage Protection Act is not applicable. Moreover, a lost artwork is also a subject of bona fide acquisition; however, if the relevant artwork is either stolen or lost, the original owner has the right to demand the return of that artwork within 2 years of being stolen or lost according to the Section 250 of the Civil Act. Also, if the buyer purchased from a distributor specializing in the artworks, such as auction, open market or gallery, the buyer could request a compensation of the purchase price from the original owner, and if the buyer purchased through a private transaction, the buyer cannot demand a compensation of the purchase price and must return the artwork.
