After train fire accident in Daegue, many research on train fire safety improvement have been carrying out. Since many alternative fire safety measures can be applied in our railway system, the effect of the each safety measure must be quantified prior to the safety investment. In order to estimate the effects of each safety measure quantitatively, fault trees and event trees are constructed in this study. Results can be applied for cost-benefit analysis or sensitivity analysis for safety measures in risk assessment process.

North Korea and South Korea agreed to refer their investment disputes to arbitration by adopting' Agreed Minutes on Procedures of Settlement of Commercial Disputes' on 16th December 2000. According to the Agreed Minutes, the two Koreas were to establish an arbitration commission within 6 months after the Agreed Minutes had been signed. In 2002, North Korea enacted laws to draw interest of foreign tourists to Mountain Kumgang and to boost investment into the region of Kaesung as it provided in those laws that commercial disputes should be settled by arbitration or judicial procedures. In October 2003, the two Koreas succeeded in adopting another Agreed Minutes as to the establishment and functioning of North-South Arbitration Commission. The fact that the two Koreas have agreed to establish an arbitration commission is meaningful since they are leading their lives quite differently in political, social, and economic sense for more than a half century. Although there still remain doubts as to the North Korean policy on nuclear matters, an arbitration commission could be a cornerstone for the set-up of the dispute settlement system between the two Koreas and a great help for investors from South Korea to pursue their possible legal claims as North Korea is eager to invite South Korean businessmen and other foreign investors to invest in its special economic areas. According to the Agreed Minutes of 2003, the two Koreas are going to adopt procedural rules for the arbitration commission. It will be a great challenge for them to agree on specific issues as to the operation of the arbitration commission. They have to set up a rester of arbitrators respectively and may have to enact or revise their own arbitration laws and rules reflecting the Agreed Minutes of 2000 and 2003. It is quite welcome that the two Koreas have agreed to set up an arbitration commission rather than resort to political or diplomatic means to settle their disputes. The success of the arbitration system between the two Koreas will make sure the safety of investment environment in the northen part of the Korean Peninsula and will bring the peace to the Korean peninsula earlier than expected.

The tilting train is able to tilt its body towards the center of the turning radius, preventing roll-over of the train as it runs on a curved rail at high-speed. This train, widely accepted for commercial purpose internationally is very beneficial in that the operating time is shortened without much capital investment to the infrastructure where there are many curved rails. Over several years, the Korea Railroad Research Institute(KRRI) has developed such a train. In this paper, the safety of the Korean tilting train express(TTX) is investigated using a dynamic simulation model. Since, proper safety standards have not been established for the TTX, those for the Korean train express(KTX) is employed instead to analyze the safety and ride comfort of the TTX. This study will prove useful in predicting the behavior of the TTX and ride comfort, and conforming that designed TTX measures up to the safety standards. It would be useful to recommend proper normal operating speed and determine the maximum safety speed, according to the result. Furthermore, it would be possible to provide basic reference data when analyzing the dynamic effect of the catenary system and the fatigue of the bogie.

The enterprise are facing potential SHE(safety, health and environment) of major industrial accidents to cause casualties or a financial loss and increasing social responsibility. So, SHE management system has to be voluntarily accomplished rather than passively with regard to SHE regulation. In this study, KW_SHE(Kwangwoon Safety, Health and Environment) management model is developed which materialize self-regulation SHE management system of individual work-place by the research and analysis of many domestic enterprise. This KW_SHE management model is intend to assess work-product vs. management expenses investment and critically evaluated for studying its benefits and limitations.

For the world's safest air traffic, safety-related areas through the large investment made in a sufficient safe level, but the airport's lack of safety management is concerned about the safety. Airside area is essential area for the flights, and activities of safe management in airside area is very important. Grafting of airside safety management and IT, importance of the safety and efficiency is growing. Advanced airports of world has applied GIS over 10 years ago, and through applying GIS, Airports GIS has been a specialized area. Therefore, this research is for geographic information standards and related laws, providing a guideline of regulations and standards for AIXM (Aeronautical Information Exchange Model), RTCA DO-272A (USER REQUIREMENTS FOR AERODROME MAPPING INFORMATION), FAA Advisory Circular 150/5300 -18A (General Guidance and Specifications for Submission of Aeronautical Survey to NGS: Field Data Collection and Geographic Information System Standards), and by analyzing aviation information and air map(notice "Civil Aviation Safety Authority No. 2009-1"), provide the direction of standardization for air map.

To study the developments and variations of unsafe behaviors in nuclear power plants thus reduce the possibility of human-related accidents, this paper, based on the Game Theory, focused on the changes in benefits of the Department of Management, Operational and Emergency in a nuclear power plant, and established the expected revenue functions of these departments. Additionally, the preventive measures of unsafe behaviors in nuclear power plants were also presented in terms of these 3 departments. Results showed that the violations of the Operation Department (OD) and the Emergency Department (ED) were not only relevant with the factors such as their own risks, costs, and the responsibility-sharing due to accidents, but also affected by the safety investments from the Management Department (MD). Furthermore, results also showed that the accident-induced responsibility-sharing of both the OD and the ED would rise, if the MD increased the investments in safety. As a result, the probability of violation behaviors of these 3 departments would be attenuated consciously, which would reduce the unsafe behaviors in the nuclear power plants significantly.

Recently because of high-speed operation of trains, railway crossings become more and more hazardous components among the whole ones of railway system. It is desirable to remove all the railway crossings for reducing fatalities at railway crossings. it is impossible to eliminate all the crossings for unrealistic investment, so it should be considered to construct multi-level crossings by the order of priority. In this paper operation conditions, various hazard factors on the train accident at domestic railway crossings and foreign cases of risk-based safety assessment models are reviewed and then necessary record data that be added and modified, some essential considerations for developing railway crossing safety assessment software program are proposed.

To establish the national railway safety system, the railway total safety technology development project has been promoted by Ministry of Construction and Transportation (MOCT) since August 2004. The project has producted successful results in many areas of railway safety, however, it is required that the research field should be re-examined to meet the aim of the project. To do that, the precedence of the investment of research resources should be reviewed and determined. The risk of serious railway accidents such as train collision, derailment and level crossing accidents are estimated. From the estimation result and the statistics on the railway accidents over fast few years, the risk factors of railway accidents can be calculated.

Change in labor time is affecting occupational safety and health. Recently reduction in labor time brought innovational operation method, investment in plant and equipment, and flexible labor time in some companies, thereby affecting working conditions for labourers. However, working conditions for some vulnerable social groups have deteriorated. As a result, they are becoming more exposed to risk factors such as injury and emotional stress. In this study we use 2014 KWCS data in order to find the social and demographic characteristics in Korean working conditions. To this end, we use exploratory data analysis approach to find the relationship between some of the important variables in the KWCS data. We also use Press-State-Response model to find which group of people are vulnerable to Press and State. We find that women, people over age 50 and business owners are more vulnerable to Press and State than men, people below age 50 and wage workers.
