국내외 여객선, 크루즈선의 이용자는 매년 빠르게 증가하고, 플로팅건축물 등 새로운 해상주거활동공간의 필요성이 커지고 있다. 그러나 지난 10년간 매년 평균 15건 이상의 선박사고가 발생하고 있음에도 불구하고 아직까지도 여객선 승선객의 재난대응능력과 안전의식에 관한 연구는 매우 미흡한 실정이다. 본 논문은 국내 여객선 이용자의 안전의식을 분석하고 문제점을 파악하며, 또한 국내 기준에 맞는 피난 시뮬레이션의 기초자료가 될 데이터를 확보하기 위해 승선생활에 익숙하지 않은 일반 승선객 394명을 대상으로 설문조사를 실시하였다. 연구결과를 정리하면 다음과 같다. 여객선의 안전성에 대한 일반 승선객의 신뢰도는 32.3%로 낮게 나타났다. 선내에서 진행된 안전교육에 대해서는 불과 14.6%만이 인지하였다고 응답하였고, 배의 피난경로 확인(42.2%)과 구명정 위치 확인(40.9%) 비율도 높지 않게 나타났다. 안전한 피난 기준은 73.3%가 선내 구조에 익숙한 승조원의 지시에 따라 피난활동을 하겠다고 응답하였다.

This study aimed to reduce of traps incident of metro train door by suggesting preventive actions throughout analyzing why railway drivers and passengers commit unsafe behaviors which are human factors making occurrence of the incidents. The incident cases were analyzed and Incident Tree was structured by brainstorming with safety experts. In addition, the questionnaire survey was conducted for comparison with the analysis results. As the result, this study suggested driver's factors, passenger's factors, and public relation plan for safe use of metro in order to reduce the frequency of the incidents. For driver's factors, implementing job-rotation systems between railway and non-railway drivers, installing Object Detection Sensors between the metro doors and PSD, and flexible operation of dwell time were suggested. For passenger's factors, placing a platform safety person, installing a safety fence in front of the stairs and the elevators, and country wide public relations through mass media were suggested.

The passenger cabin of train is generally insulated from exterior environment to ensure the safety of passengers and to enhance the heating and cooling efficiency. Therefore, the IAQ management of passenger cabin is very important in aspect of amenity and health of passengers. In this study, we measured some IAQ factors influencing on the indoor air quality of passenger cabin. The measurement was carried out to investigate the PM-10, PM-2.5, PM-1.0, temperature, relative humidity, carbon monoxide, carbon dioxide leves of KTX. The results showed that the air quality of the cabin was largely satisfactory, but carbon dioxide level was relatively higher. The control of carbon dioxide levels need the extensive research in the future.

Thermal comfort inside a passenger car has been receiving large attention in automobile industries. Especially, the performance of windshield defroster is important in the design of a car to ensure passenger comport and safety. Thereby, better understanding on the ventilation flow along the vehicle windshield is essential to evaluate the performance of windshield defroster. However, most previous studies dealt with the defrost flow using CFD (computational fluid dynamics) calculations or scale-down model experiments. In this study, a real commercial automobile was used to investigate the flow discharged from the vehicle defroster and the ventilation flow along the windshield using a PIV velocity field measurement technique. The experimental data would be useful to understand the flow characteristics in detail and also can be used to validate numerical predictions.

This paper presents a simulation for passenger ship evacuation considering the inclination of a ship. In order to describe a passenger's behavior in an evacuation situation, a passenger is modeled as a rigid body which translates in the horizontal plane and rotates along the vertical axis. The position and rotation angle of a passenger are calculated by solving the dynamic equations of motions at each time step. To calculate inclined angle of damaged ship, static equilibrium equations of damaged ship are derived using "added weight method". Using these equations, physical external forces due to the inclination of a ship act on the body of each passenger. The crowd behavior of the passenger is considered as the flock behavior, a form of collective behavior of a large number of interacting passengers with a common group objective. Passengers can also avoid an obstacle due to penalty forces acting on their body. With the passenger model and forces acting on its body, the test problems in International Maritime Organization, Maritime Safety Committee/Circulation 1238(IMO MSC/Circ.1238) are implemented and the effects of ship's inclination on the evacuation time are confirmed.

Traffic safety and vibration serviceability of a railway bridge set a limitation to the application of long-span cable supported bridges even though the design trend of the bridge becomes longer and lighter. In the case of high speed railway, it becomes more severe for the high speed of the train and resonance of the structure. Therefore, the cable supported bridge does not exist in Korea high speed railway until now. On the other hand, in recent, Italia, Japan and China do design and construct the long-span cable supported bridges for high speed railway recently with overcoming of traffic safety and passenger comforts. In the present study, prior to analysis of traffic safety and passenger comforts, a extradosed bridge for common railway is re-designed for high speed railway. The difference of member forces and displacements by design live load, the difference of impact coefficient and variable stresses of cables are investigated.

The safety at this study is investigated by flow or stress analyses due to configuration or installation direction of fuel tank in the existing CNG bus. In case of the lower ceiling with sharp type, the equivalent stress due to the explosion of fuel tank is less than the type of flat or arc. it becomes safer on passenger. In case of the installation direction of fuel tank in the existing CNG bus, the stress applied on the lower ceiling at transverse direction becomes less than at longitudinal direction. It is more stable on the safety of passenger. The harm on the explosion accident can be prevented by use of the analysis result at this study.

The sub-frame of passenger car begins to be used widely for the safety of passengers. Conventional design of the sub-frame comprises 22parts, and it requires quite complicated production processes. In this papers, the sub-frame is designed with TWB(Tailor Welded Blanks) to improve stiffness, to reduce weight and to simplify the manufacturing process. To design the proper structure, structural analysis and crash analysis are executed about the conventional design and TWB applied design. A prototype TWB applied sub-frame is manufactured using mash-seam welded TB(Tailored Blanks). Comparing with the conventional sub-frame, the TWB applied sub-frame has 30% weight reduction and 17% increasement of structural stiffness in average.
