Ail of the world, unification and extension of market enlarged scale of international commerce. Thus, not only production but also circulation of goods is brought into relief and transportation of most freights is performed using container. Container vessels are equipped with marry kinds of securing equipments such as Lashing, twistlock. Lashing is installed mainly in container vessel for the container stack with more than 3 containers. Damage of containers often arise from irrelevant lashing arrangement and bring economical loss. Much time and cost is requested for the Calculation of forces on container and determination of lashing arrangement In this study, We developed lashing analysis simulator which performs calculation and presenst relevant lashing arrangement. It will provide more convenient and efficient environment for lashing analysis.

Environment friendly architecture, which will reduce shortcomings of current architectural culture, can be achieved by using natural energy and environment friendly building materials together with their environmental architecture techniques. Particularly, even though the overall building system is perfect, it cannot be considered as comfortable architectural space if the materials are polluted, harmful to human bodies and producing wastes. Therefore, in order to build environment friendly architecture, the selection of the materials is very important and necessary from the planning stage with careful reviews and concern. This study tries to define what the environment friendly materials we, to investigate and to classify them, in order to provide some guidelines for selecting them at plans to build. For examples, the materials can be classified into natural materials, continuously usable materials, recycled materials from wastes, and less polluting materials mixed with natural materials. Finally, this study reviews the existing products in the market and proposes to develop new ones in the future. It will present the circulation of resources in the 21century through recycled and reused materials.

Purpose - The objective of this study was to examine the volatility of the exchange rate of the Somali shilling (SoSh) during 2010, especially the exchange rate between the Somali shilling and US dollar. Research design, data, and methodology - The study employed aquantitative research design; the data was analyzed using contents analysis for the data pertaining to the exchange rate between the US dollar and Somali Shilling in 2010. Results - The main findings were that the exchange rate was very volatile during 2010 because of three sources: (1) Imbalance of demand and supply in the money market, (2) People adopting the US dollar as the medium of exchange forgoods and services, thereby reducing the circulation of the SoSh, and (3) Lack of a strong central bank. Conclusions - The study suggested three possible remedies: the establishment of an effective central bank that matches the demand and supply of the currencies, adoption of the Somali shilling as the official currency base for the prices of commodities, and minimizing the imports into the country and maximizing its exports, to support the strengthening of the Somali shilling.

Service and technology for the future hyper-connected society, which is every information receive through the mobile internet, will be an Internet of Things. Thus, it is mandatory to derive key standardization work item and establish strategy for the global business with the standardization of device and service platform by the application service. In this study, by analyzing the domestic and international market trends, state of technical development, and standardization of technology, we identified the open platform is the stepping stone for achieving the goal which is establishing the virtuous circulation of IoT ecosystem. Also, we defined emphasized key standardization work item for achieving the open platform are network, server, access authentication, billing system, and software platform. After that, we proposed future strategy direction of standardization. This research could be contribute to the IoT service diffusion by realizing IP communication among low power wireless terminals and implementing light-weight standard internet protocol.

Economic and political barriers in Northeast Asia including Korea have been eliminated gradually. As results of economic relations are more active in this region. The administration of physical distribution tightened circulation- cost down. This is one of the most important facts to develop world economy. Distribution in China is expected to grow quantitatively and continuously. China is just out of planned economic system. Therefore, it is expected that foreign affiliated firms will take a fierce competition for the next $1\sim2$ years. This study investigates Korea-China trade and distribution index with analysis and expectation of China market. The study analyzes the business conditions, faced problems and differentiated strategies of foreign affiliated firms. Be based on those, it is researched how domestic companies will make strategies to start China successfully.

Korean dairy industry is placed on the very critical situation with the progress of free trade marketing system internationally. To keep and improve the dairy food market, better measures are imperative for dairy industry. Especially, the milk distribution system is premodern to some extent, in comparison with both the production and the processing part of dairy industry. Reform measures for the promotion of domestic milk consumption by lowering the distribution cost are as follows. First, out-sourcing of the logistics department can decrease the circulation cost of milk. Secondly, milk should be packed into large-size package(more than 1 liter) to save both package and distribution cost. Thirdly, milk should be distributed from plant to consumers through the hygienic distribution system including perfect cold chain system, Above reform measures can not come true through the efforts taken by one company but through co-worker, concerted research, and joint in-vestment among dairy companies that can reduce the distribution cost and provide consumers with the best service, eventually resulting in the increment of milk consumption.

This paper is intended to trace and management of drug based on RFID Technology at a circulation market, from manufacturer to end user, of drug. To avoid counterfeit and generic drug and establish of order in the circulation of drug, at the moment of manufacturing, tags for each bottle and each box are tagged. and then from factory to hospital, through whole logistics, e-pedigree for the drug is made and monitored. Using inventory information, it is easy to manage and control stock of drug. In addition to, RFID System enables storing and delivery to be simple, process time to be shortened. As this research is to study of applying RFID to drug, in this paper, standard RFID code for drug is suggested and tried to apply domestic middle win. Finally, the result of tag pattern design and how to tag for the drug based on 90Mhz is proposed

Purpose: Recently, domestic and abroad consumption of mushroom has been increasing. Especially, oyster mushroom has been the most consumed product, sharing one third of the mushroom market. The air temperature differences between relative positions of the mushroom farms were needs to be minimal. However, in reality, the air temperature differences ranged from 2 to $5^{\circ}C$. Because of this, the mushrooms are non-uniform growth as well as decrease in both quality and quantity. Although air circulators have been employed by oyster mushroom farms to minimize air temperature differences, no experiments have been performed to illustrate the effect of the air circulators. Methods: This experiment is designed to analyze the effect of the air circulation by constructing a prototype air circulator and measuring the air temperature when the circulator was position at different heights (50 cm, 150 cm, 200 cm) from the floor in the center. Result: The horizontal plane air temperature of the first growing bed when the air circulator was installed 50cm above the floor in the center, once not using the air circulators and the other time using the air circulators, yielded the air temperature differences of $8.6^{\circ}C$ and $1.8^{\circ}C$ and deviations of 2.82 and 0.60, respectively. The third growing bed's air temperature differences were $10.0^{\circ}C$, $1.6^{\circ}C$ and deviations 3.28, 0.64, each respectively. These outcomes proved that the use of air circulators minimized the air temperature difference and deviation. The use of air circulators helped minimize the air temperature differences and the derivations in oyster mushroom farm. Conclusion: The use of air circulators helped balance the air temperature distribution in oyster mushroom farm.
