KARI is now developing KSLV-II which can insert 1.5ton satellite into the orbit, and system design review is close at hand. As a part of mission assurance for space launch vehicle, reliability and safety management is being performed and to assure the safety, KARI has been doing actions on the basis of the safety assurance plan and system safety program plan. In this study, preliminary hazard analysis is reviewed and the result for the propulsion system will be illustrated. The result will be used as a reference for the safety and risk management.

According to industrialization and urbanization the number of increasing cars is attributable to an explosive increase of the vehicle emissions. In this study, in consideration of the population and local transportation characteristics of South Chungcheong Province the environmental and economic cost-benefit analyses are performed to evaluate whether the CNG bus conversion gives what kind of effects. Based on the analysis result the expansion and distribution plan of CNG bus is proposed for South Chungcheong Province, and the local supply policy model is also proposed considering the acquisition and management of the economic situation of CNG charging infrastructure and the small transportation companies.

The Korean railway standards (KRS), formerly managed by Korea Railroad (Korail), have been managed by the Korean Ministry of Land, Transport and Maritime Affairs (ML TM). According to Korean railway safety law and its ordinances, which were established for the guarantee of railway safety, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute (KRRI). Currently, a total of 195 standards has been managed from the various railway applications including track, electrical, and vehicle areas. Moreover, according to the guideline on the management of KRS, the conformity of KRS with international standards is encouraged for the enlargement of international trade. In this investigation, a brief management activity of KRS and the recent activities on conformity of KRS with AAR standards on automatic coupler will be introduced.

Because recently(July 14, 2011) fire occurred in the engine room of a moving taxi under Namsan Tunnel 1, 51 vehicles' driver and more than 250 passengers in the road tunnel were urgently evacuated with abandoned vehicles. Vehicle fires in Namsan Tunnel that day, Sufferers struggled to escape quickly difficult to escape the two-way by abandoned vehicles on the road and to fear many casualties by using vehicle fuel and combustible interior and the driver who is ignorant of vehicle accident continuous entered in the road tunnel had accessibility the site of fire department was more difficult. In this study, It is to investigate structure and basic materials, such as fire extinguish equipment and facilities for damage prevention and to analyze the problems and to plan improvement method of fire extinguish equipment, facilities for damage prevention and transportation facilities(Large traffic signs, Breaker, etc.) on the Namsan Tunnel that in the long-term plan is prepared to strengthen for accessibility of the site of fire department in case of Vehicle's fire.

The inventory routing problem (IRP) is an important area of Supply Chain Management. The objective function of IRP is the sum of transportation cost and inventory cost. We propose an Artificial Immune System(AIS) to solve the IRP. AIS is one of natural computing algorithm. An hyper mutation and an vaccine operator are introduced in our research. Computation results show that the hyper mutation is useful to improve the solution quality and the vaccine is useful to reduce the calculation time.

Approximately 95% of the world's trade moves by containers, primarily on large ships, but also on trains, trucks, and barges. The system is efficient and economical, but vulnerable. However, the rise of terrorism and the possibility that a container could be used to transport or actually be the delivery vehicle for weapons of mass destruction or high explosives have made it imperative that the security of shipping container system be greatly improved. This study proposed a trend of container security and its Countermeasures.

The vehicle has many technique change from The requirement of the safety the energy environment and convenience dimension is an enlargement toe. This is keeping changing the paradigm of the vehicle industry rapidly. The change to be technical such brought the intelligence of the former control device. And this organizes a sensor network among each systems and makes new traffic system. This paper a standard framework based on Sensor. We call it Vehicle Management System. The VMS used MOST network and It is able to make the stability of the component swap time or vehicle order the greatest.

This study is to find out how much elementary school members have their consciousness against safety in their school. Simple questionnaire 1206 sheets have been distributed to the members and additional interview with teachers to take care of them. Statistically, frequency, and correlation analysis have been made and chi-test has also been made for data reliability. The results of these have been summarized as running on corridor with 53.4% in school safety, warming up exercise 45.2% in leisure safety, evacuation form classroom with 2.4% in fire safety, crossing around just in fromt or rear of vehicle with 61.2% in transportation safety. It is thought that safety training should be provided to more for man than for girl pupils and also, safety consciousness should be improved than all the other area.

The respective delivering vehicle loaded with the own cargo moves into the respective delivery area. At the base, the delivery points D1 and D2, for example, have the same starting point but the destination is different. The average delivering time of the delivery vehicle is mostly more than 8 hours a day. Therefore, the efficiency of delivery is generally low. In this study, the deliveries will be forwarded from a base station to a delivery point where cross docking will be applied to a single vehicle, and will be distributed from the cross docking point through cross docking. If the distribution is implemented, one vehicle will not have to be operated from the base to the cross docking point. In that case, logistics cost will be reasonably saved by the reduction of transportation cost and labor time. If one vehicle only runs from the base to the cross docking point, each vehicle will be operated in two shifts, and the vehicle operation can be efficiently implemented. This research model is based on the assumption that the 3 types of ratios between the traffic volume of the vehicles starting at the base and the vehicles waiting at the cross docking point are set to the first ratio of 30% to 70%, the second ratio of 50% to 50% and the final ratio of 70% to 30%. As a result of the study, The delivery time in the cross docking point is much higher than that in present on the condition that the cargo volume in the D2 area is more than 50%. Likewise, the delivery time is slightly higher on the condition that the cargo volume is less than 50%. Time is reduced in terms of 50% model like AS-IS model.
