In this study the economic impacts of government support of shipping industry in the labor rich country are appraised in a general equilibrium model. Shipping industry subsidies (which are supposed to be supplied by lump-sum tax) will decrease disposable income by shifting productive resources from traded goods to the comparatively disadvantageous transport sector, and at the same time reduce the implicit tariff effect by lowering transport costs. The net effect of shipping industry subsidies is to increase social welfare because the latter positive effect of shipping industry subsidies is to increase social welfare because the latter positive effect dominates the former negative effect. Such an increase in social welfare can never be expected from competitive traded goods industry subsidies in the case of which social welfare will actually decrease because of inefficient resource allocation resulting from the subsidies. In addition it is worth noting that the subsidies on the most capital intensive shipping industry will rectify unevenness in income distribution by raising relative price of labor contrary to subsidies on capital intensive traded goods.

This research reviews regulations on logistics/transport industry and attempts to quantify the effects of regulation mitigation on GDP per capita. South Korea's transport industry has been gradually expanding, however, the industrial structure is still short rooted. In 2014, average number of hours worked is 5th highest and wage margin 12th smallest out of 18 industries. Furthermore, the regulations for this industry appear to be stricter than those of other industries. OECD's logistics/transport industry regulatory index for South Korea has been decreasing for the last 40 years but still exceeds those of EU, Japan, US, and other countries. This paper provides supporting reasons for regulatory reforms by analyzing the ripple effects on real GDP. Factors such as the ratio of trade among GDP, the enrollment rate to primary school, energy usage per capita, and population are controlled in the fixed-effect model. Estimation results showed that 1 unit decrease in transport/logistics regulatory index is correlated with 8.1% increase of the real GDP per capita, that is, 10% of deregulation is expected to yield 2.16% increase in GDP per capita. Thus, it is expected that mitigating regulations on market entries, price determination, ownership structures of network industry, vertical integrations can improve the economy of South Korea.

Subject : The Practical Use of UN Standard Message for cargo flow EDI Writer : Park, Nam Kyu and Lee, Tae Woo It's necessary to prepare standard message which is agreed on among trading partners for EDI in container transport industry. Now KMPA is carrying out the EDI Project for establishing Korea Logistics Network. It is important to make standard message of documents using in transport industry to succesfully accomodate EDI. The objective of this study is to find out the method of UN standard message utility in Korea. For this study, the UN message guideline is primarily reviewed, and the process that Shipping Request being used in Hanjin Shipping Co. Ltd. is applied to UNSMs as case study. Generally the data format of EDIFACT is so complex and broad for inter-industry standard that the abstract of data format is usually used. Therefore, it is necessary to make the subset of standard message for Shipping Request in ocean industry. In the result of this study, that the ocean industry can use the subset of IFTMBF for Shipping Request is proved, and the subset is suggested. This thesis will contribute toward showing the practical way of standardrization of 350 documents using in trade, customs and transport sectors.

The Climate Change has been emerged as one of the most important social and economic issues and is affecting our daily life. The Post-Kyoto Protocol aims to reduce GHG(Greenhouse Gas) emission and mitigate climate change. Under this protocol, developed countries which are classified as Annex I implements programmes and strategies confronting against the climate change. South Korea has set voluntary GHG reduction goal of 30% reduction compared to BAU(Business As Usual) in 2020 and prepares National GHG inventory system and Negotiated Agreements(NA) with industries. It will affect seriously to industry and transport sector and its obligation to reduce GHG emission will be strengthened gradually. Therefore, there will be large impact on industry structure. In Korea, various strategies against climate change are being prepared as researches of development of GHG emission reduction technologies and integrated GHG emission management system in transport sector. In this study, strategy on climate change in transport sector is proposed by being based on developed countries' respond to climate change in transport sector.

This simulator is developed for the analysis of a MOSFET based on Thermally Coupled Energy Transport Model(TCETM). The simulator has the ability to calculate not only stationary characteristics but also non - stationary characteristics of a MOSFET. It solves basic semiconductor devices equations including Possion equation, current continuity equations for electrons and holes, energy balance equation for electrons and heat flow equation, using finite difference method. The conventional semiconductor device simulation technique, based on the Drift-Diffusion Model (DDM), neglects the thermal and other energy-related properties of a miniaturized device. I, therefore, developed a simulator based on the Thermally Coupled Energy Transport Model (TCETM) which treats not only steady-state but also transient phenomena of such a small-size MOSFET. In particular, the present paper investigates the breakdown characteristics in transient conditions. As a result, we found that the breakdown voltage has been largely underestimated by the DDM in transient conditions.

The objective of this paper is to measure the relative technical efficiency of Korean railway transport service. Previous studies on the efficiency in Korean railway service have carried out before the structural reform of Korean railway industry in 2004, whereas this study used the latest data which reflected the impact of reform. We analyzed the efficiency in Korean railway transport by means of measuring the technical efficiencies of other countries, these were estimated with data envelopment analysis. DEA has gained great popularity in measuring efficiency in transport industry, school, government, hospital and so on in recent years. This analysis could serve as peer to help improve performance of the railway management and operation.

Proton Induced X-ray Emission (PIXE) is a MeV ion beam analysis method for use with particle accelerators. PIXE uses low-energy charged particles as an excitation mechanism to generate characteristic x-ray emission from each element in a target. In PIXE analysis, the beam current used is from a few nA to several tens of nA. Chosun University (Cyclotron Research Center) designed a $50{\mu}A$ beam line from the 13 MeV cyclotron for use with a PIXE analysis system, as well as performing beam transport line optimization research. In this study, the beam line operation conditions for the optimization process of beam transport and beam characteristics are shown.
