The key features of maritime accidents are the change of their attributes by new risks from time to time. To prevent maritime accidents in Korea, the impacts by new risks on domestic safety environments should be identified or predicted. The purpose of this paper is to find the hazard factors by new risks on maritime safety in Korea. The meaning of new risks is the elements of accident hazard which is compiled from new or rare or unprecedented events in the worldwide maritime transportations. The problems of new risks are the lacks of optimum countermeasures to mitigate accident risks. Using the questionnaires with 152 event scenarios classified by 20 accident causes, the hazard identification and risk analysis of new risks was performed based on the Formal Safety Assessment (FSA) by IMO. A total of 22 Influence Diagrams, which is to depict the transit flows between accident causes to consequences, is used in the construction of 152 event scenarios. A total of 20 accidents causes is the same contents as the causation factors represented in Statistical Year Book for Maritime Accidents of Korean Maritime Safety Tribunals. After defining the evaluation equations to the response results of questionnaires by 46 experts, the work for risk analysis is carried out. As results from the analysis of 152 scenarios, it is known that the root cause to affect on maritime safety in Korea is the pressure of business competition and it led to the lacks of well experienced crews, the overload of vessel operations and crew's fatigue. In addition, as results from the analysis of 20 accident causes, the three accident causes are to be candidate as main issues in Korea such as the inadequate preparedness of departure, the neglecting of watch keeping in bridge and the inadequate management of ship operations. All of the results are thought to be as basic hazard factors to safety impediments. It is thus found that the optimum Risk Control Options to remove the hazard factors and to mitigate consequences required are the following two factors: business competition and crewing problems.

PURPOSES: This study analyzes the characteristics of traffic flow on freeway sections under daytime and nighttime conditions to improve traffic safety, and suggests a method to estimate an accurate freeway capacity value that reflects these characteristics. METHODS : The trends and differences in capacity were investigated using comprehensive field data collected under both daytime and nighttime conditions on freeway sections with designated speeds of 80, 100, and 120 kph. RESULTS : The capacity values under nighttime driving conditions were reduced by 3.3%, 6.9%, and 8.8% at 80, 100, and 120 kph, respectively. Several nighttime adjustment factors were deduced for each designated speed category from the analysis results. CONCLUSIONS : It is expected that more accurate capacity values can be estimated for freeway sections under nighttime conditions by applying the resulting adjustment factors. In addition, traffic safety will be improved through the increased efficiency of traffic management on these freeway sections.

Aviation safety is increasingly important to secure the safety of the Republic of Korea Air Force (ROKAF). A critical activity for enhancing aviation safety is to analyze an accident throughly and to identify causes that can explain it reasonably. The results of such a systematic accident investigation can be effectively used for improving information displays, task procedures, and training systems as well as for reorganizing team structure and communication control system. However, the current practice of analyzing aviation accidents in ROKAF is too superficial and simple to diagnose them systematically. Additionally, the current practice does not give a full consideration to human factors that have been identified as main causes of most of the aviation accidents. With this issue in mind, this study aims to suggest a new approach to analyzing aviation accidents related to human factors.The proposed method is developed on the basis of several models and frameworks about system safety, human error, and human-system interaction. Its application to forty-two human factors-related accidents, which have occurred in ROKAF during the last ten years, showed that the proposed method could be a useful tool for analyzing aviation accidents caused by human factors.

As of Dec. 31, 2011, the number of nation's escalators accounts for 24,248 units, 5.4% of total elevators in our country, safety accidents take up as many 539 case, 55.2% of total elevators' safety accidents. Escalator safety accidents show high incident ratio of primary safety accidents breaking out by users' careless and abnormal use type, taking up multi-caused accident, which mainly take place from vulnerable age groups such as children under 13, and elders above 65. The Government will have to devote itself for policy and support for the establishment of safety management system fit for current state, the revitalization of preventive education for safety accident, the enhancement of safety awareness to escalators' users in order to secure escalator safety environment on an international level and support domestic industrial development.

The purpose of this study is to understand the safety factors of the public transportation and recommend the experimental factors of customer satisfaction. The survey consist of 28 questions of 5 factors about users characteristics on roads, railways, ships, and flights. As a result of multiple regression analysis, we knew that there are three potential factors affecting customer satisfaction. The Factors are named 'expected', 'attitude', 'management', and the variable of factors affect customer satisfaction significantly. Therefore, it is good strategy for effective working to improve customer satisfaction that maintain attitude with safety minds, try to specialized management, and creating expectation for safety considering the difference by the type of public transportation. After considering the meaningful result, for the development of policies for customer satisfaction for safety, we have to consider expected, attitude, and management factors of workers and officials that influence customer safety and try to improve the managerial factors considering the characteristics of their own.

Global tourism has increased throughout the 1990s, with the biggest surge occurring in the Asia-Pacific region. Long-distance travel is also increasing, and at a rate faster than the global average. The opportunities for event tourism appear to be strong almost everywhere, although we know from recent history that recessions like IMF impacted on these destinations. Along with this upward trend, competition for more desirable tourists is also surging, so destinations cannot be complacent (Getz, i997). Event tourism is appearing as the powerful method In the fierce competition around the tourism industry. This paper investigated the safety factors considered by visitors of 2000 Gyeongju World Culture Expo in Korea and analyzed the correlation between the safety factors and the demographic characteristic of the visitors.
