This study is about a feasibility study for the practical using Urban Transit Maglev system based on systems engineering. First of all we defined what phase is matched with the project for feasibility study in the system life cycle and identified tasks that shall be done in the phase. Finally we suggested how to do in this project. The Urban Transit Maglev system is not wholly new system. It has similar architecture to a legacy urban railway system. But it is the system that is partially introduced new technology, because there are many projects have this characteristic within the country, we expect that this study may provide references.

Most of Cities are suffering from the traffic congestion problem with the vehicles increased. Especially, the City of Pusan is experiencing the severest traffic congestion with the lower read capacity and the higher travel demand than any other cities in the country. Thus, the purpose of this study was to grasp the conditions, review the problems and finally suggest the improvements which we faced at this time for the construction of the Urban Transportation System considered in Pusan area. Based upon the results, it was concluded that firstly the Urban Transportation System(UTS) in Pusan area should be constructed by the Public Transportation System in the center of the Public Transit Modes(i.e., bus and subway), secondly the Para-transit Modes(i.e., Light Rail Transit, LRT) introduced, and thirdly the Transportation Demand Management(TDM) implemented with the expansion of the transportation facilities if possible.

This study aims to present about current status of logistics in Mongolia. As a landlocked country have limited the role of a maritime transportation is a very poor country. However, Mongolia is a rich country in mineral resources in the world and became a center of increasing international trade. Therefore, Mongolia wants to develop logistics as other developed countries using a strategic location. Mongolia uses international port for transit China and Russia by railway. First, this paper focuses on discussing the current situation of logistics. Second it points out some issues currently facing by the governmental policy to promote. Finally, this paper presents some recommendations for developing logistics in Mongolia. The geographical remoteness of Mongolia which results in high cost of transport causes problems for trade relations with the rest of the world to grow.

Our country is promoting the introduction of new means of transportation due to insufficient supply according to the existing demand of road traffic. Among them, manless light railroad transit is settled down as the most definite alternative. However, new traffic systems such as manless light railroad have certain difference between characteristics of hardware and software and subway system. Therefore, there will be many differences compared to the existing contingency system when accidents occur. Railway management organization has to establish railway contingency plan and acquire permission from the minister of the Ministry of Land, Transport, and Maritime Affairs. However, as commercial transportation is available, a new traffic system also should establish contingency plan. Therefore, the establishment of systematic contingency plan is suggested in order to analyze characteristics of manless light railroad in the beginning of introduction and to make contingency response available.

This paper will introduce the safety authorization system for light rail transit(LRT) through investigating safety certification & safety authorization in foreign country and aviation field in Korea. The safety authorization system proposed by the government these day was also investigated. Korea Transportation Safety Authority(KOTSA) have conducted safety validation process on Busan-Gimhae LRT before its revenue service during three months since Jan. of 2011. We describe the overview of these validation activities, results and safety certification issued. Learning from this process, we propose the standardized safety validation process including checklists which can be applied to common unmanned light rail system. This study will be a basis of railway safety authorization for LRT and will be continually improve its application ability by the future study.

High cost of crude oil imposes a heavy burden on vehicle users. Thus, much efforts are given to the development of alternative energies in advanced countries as well as our country. Among them, fuel cell is emerged as the most promising one for transportation. There is no harmful emission with hydrogen energy of which sources are abundant on the earth. The use of both fuel cell with self-generating system and electromanetic guidance system will be able to make urban track rapid transit operate even in the city areas of very limited infrastructure space with flexibility and on time accessibility. The high efficiency is also expected with clean environment and easy riding for both the old and the handicapped.

In this paper, we implement an algorithm of transit signal priority control that not only maximizes service quality and efficiency of bus, but also minimizes the control delay of passenger cars using UTIS currently being deployed and operated in Seoul national capital area. For this purpose, we propose an algorithm that coordinates the strength of TSP by estimating bus demand. Typically, the higher the strength of TSP is on main street, the bigger the control delay is on the cross street. Motivated by this practical difficulty, we proposes an algorithm that coordinates TSP's strength by checking the degree of saturation of cross street. Also, we verify the possibility of field implementation via simulation analysis using CORSIM RTE based HILS (Hardware In the Loop Simulation). The result shows that travel time of bus improves about 10 percent without increasing control delay of passenger cars by TSP. We expect the result of this research to contribute to increasing the overall transit ridership in this country.

Indisputably school is the main institution that socialises migrant children into the culture of their new country. Through school they learn the new language and customs, which will enable them to become cultural brokers between the new cultural world and their families. During this process migrant children often transit a liminal terrain where their roles and identity become at the same time diverse and ambivalent. Despite the challenges involved these children often become experts in juggling different cultures, environments and expectations. This study explores the experiences of Latin American children and their families as they start primary school in Australia.

According as zone of life of big city is expanded by new city development etc.., need special skill master plan compensation which can be systematic for wide area traffic problem solution and confusion expense minimization in the metropolitan area because wide area of capital region traffic is gone continuously and continues. Accordingly, Kyonggi Province suggested rapid-transit railway achievement that can connect Seoul Gangnam in 20 minutes with Dongtan new city recently. MLTM(Ministry of Land Transport and Maritime Affaris) announced "Capital region railway network improvement plan research services (2007.12)" result that Gangnam High-speed railway route (Suse $\sim$ Dongtan $\sim$ Pyeongtaek) construction for offer High-speed railway service to capital region and Kyonggi southern part area inhabitantses and need to line capacity tribe solution by Seoul-Busan high-speed railway second-stage and Honam high speed railroad completion. Is judged that need examination about wide area rapid-transit railway combined application operation that take advantage of rail track reserve capacity of High-speed railway for utilization efficiency elevation of country and efficient investment of national finance according as High-speed railway and Gangnam rapid-transit railway route that is suggested in Kyonggi Province are overlaped. Therefore, in this research, I wish to quote investment efficiency plan of railroad business by that different kind's train is run in uniformity track by presenting combined application operation plan and working expenses curtailment effect etc. that is optimized through analysis of roadbed and E & M technology condition, intermediate station plan, train operation planning etc. in case of wide area rapid-transit railway and high-speed railway run combined application.

This study has been focused on the revisions and characteristics of the 7 non-maritime trade terms(EXW, FCA, CPT, CIP, DAF, DDU and DDP) in Incoterms 2000. Main characteristics are as follows: First, the use of different expressions intended to convey the same meaning has been avoided and the same expressions as appear CISG have been used. Second, the content of preamble in each trade terms has been shortened and definitedly. Third, if the parties are going to use variants of trade terms in Incotrems 2000, the meanings should be made clear by adding explicit wording in the contract of sale. Main revisions of the 7 trade terms are as belows: First, Incoterms 2000 has emphasized that in EXW, the seller delivers when he places the goods at the disposal of the buyer at the seller's premises or another named place(i.e. works, factory, warehouse, etc.) not cleared for export and not loaded on any collecting vehicle. Second, in FCA, delivery is completed; a) If delivery occurs at the seller's premises, the seller is responsible for loading. b) If delivery occurs at any other place, the seller is not responsible for unloading. Third, in CPT and CIP, all costs and charges relating to the goods whilst in transit until their arrival at the agreed place of destination, unloading costs and all duties, taxes and other charges as well as the costs of carrying out customs formalities payable upon import of the goods and for their transit through any country are linked with the content under the contract of carriage. Fourth, Incoterms 2000 has emphasized that in DAF, the seller delivers when the goods are placed at the disposal of the buyer on the arriving means of transport not unloaded, cleared for export, but not cleared for import at the named point and place at the frontier, but before the customs border of the adjoining country. Fifth, Incoterms 2000 has emphasized that in DDU, the seller delivers the goods to the buyer, not cleared for import(in DDP, cleared for import), and not unloaded from any arriving means of transport at the named place of destination. Sixth, if the parties do not intend to deliver the goods across the ship's rail, FCA, CPT and CIP instead of FOB, CFR and CIF should be used.
