  • In order to reflect complex and diverse building types, resident characteristics and disaster factors, it is necessary to introduce a flexible situation-based response system based on real-time information. Intelligent CCTV, hybrid sensor, location scanner, and customized broadcasting device were examined to introduce for the real-time response intelligent response system and its feasibility was verified through field test. In addition, based on the real-time information, the evacuation simulation was executed by assuming the dormitory building and the resident of the school, and the safety of the evacuation and the shortening of the pinnacle time were confirmed. The feasibility of real time information based evacuation comparing with the existing evacuation system were verified in the case of evacuation.

  • 최근 교통사고 및 교통사고로 인한 사상자수의 감소를 위해 기존의 자동차에 각종센서나 통신기술 등의 첨단 ICT기술을 융합한 첨단안전자동차에 대한 연구가 활발히 진행 중에 있다. 이러한 첨단안전자동차 기술의 시장진입 및 관련 기술 도입을 위해서는 자동차에 도입되는 첨단안전 기술에 대한 효과 분석에 따른 도입 타당성 평가가 필요하다. 본 연구에서는 첨단안전자동차 기술 중 운전자지원시스템(ADAS: Advanced Driver Assistant System)을 대상으로 효과분석 방법론을 개발하고, 개발한 방법론을 차선이탈경고장치(LDWS: Lane Departure Warning System)와 자동비상제동장치(AEBS: Automatic Emergency Braking System)에 적용한 사례분석을 통해 사고감소효과를 추정하였다. 분석결과, 차선이탈경고장치는 관련 사고유형(정면충돌, 도로외이탈, 공작물추돌, 전도전복)에 대해 약 10~14%의 사고감소 효과가 있는 것으로 나타났으며, 자동비상제동장치는 추돌사고에 대하여 약 50%의 사고감소 효과를 보이는 것으로 나타났다. 본 연구의 결과는 추후 첨단안전자동차 기술 개발에 따른 효과분석시 기초자료로 활용이 가능할 것이며, 운전자, 탑승자, 보행자를 위한 자동차 기술의 발전 및 기술도입 타당성을 제시하기 위한 근거 자료로 활용이 가능할 것으로 기대된다.

  • The important field of research in ship operation is related to the high efficiency of transportation, the convenience of maneuvering ships and the safety of navigation. For these purposes, many intelligent technologies for ship automation have been required and studied. In this paper, we propose an intelligent voice instruction-based learning (VIBL) method and discuss the building of a ship's steering control system based on this method. The VIBL system concretely consists of two functions: a text conversion function where an instructor's inputted voice is recognized and converted to text, and a linguistic instruction based learning function where the text instruction is understood through a searching process of given meaning elements. As a study method, the fuzzy theory is adopted to build maneuvering models of steersmen and then the existing LIBL is improved and combined with the voice recognition technology to propose the VIBL. The ship steering control system combined with VIBL is tested in a ship maneuvering simulator and its validity is shown.

  • Background: With the recent rapid industrialization, occupational safety and health (OSH) has become an important issue in all industrial and human activities. However, incidents of injuries and fatality rates in the Ghanaian industry sector continue to increase. Despite this increase, there is no evidence regarding the element of OSH management in transport activities in Ghanaian industries. Thus, this study aims to examine the perceptions regarding the importance of safety and health in work-related transport activities in Ghanaian industries. Methods: A survey data collection technique was used to gather information on best safety practices over a 5-month period. We randomly selected 298 respondents from industries to answer structured questionnaires. The respondents included drivers, transport managers, and safety engineers. Standard multiple regression model and Pearson product-movement correlation were used to performed the analysis. Results: The result shows that for interventions to improve safety and health, concentration has been on drivers' safety practice with less attention to safe driving environments and vehicle usage. Additionally, the respondents are aware of the importance of OSH in transport activities, but the level of integration does not measure up to the standard to reduce operational accidents and injuries. Finally, strong commitment to changing unsafe practices at all levels of operations appears to be the effective way to improve safety situations. Conclusion: OSH culture is not fully complied in industries transport activities. This study, therefore, supports the use of safety seminars and training sessions for industry workers responsible for transport operations for better integration of safety standards.

  • Autoparking assistant systems are a new and very promising area in automotive systems engineering. Since the traffic in modern cities becomes more intense, it is getting harder for a driver. Those systems are necessary for an inexperienced one to find a proper parking slot, or to park in a narrow parking slot without damaging his car or the vehicles around. The implementation of autoparking assistant systems may reduce drivers' stress and make parking generally more comfortable. In addition, such system can be extremely useful for senior or disabled people or for drivers with reduced mobility. The implementation of autoparking assistant systems may increase the safety of the parking, and therefore the development of such systems is a highly-demanded task. We introduce an intelligent autoparking system that automatically generates trajectory for parking using a fuzzy logic. This paper consists of three parts. In first part we introduce trajectory generation method for parallel parking without collisions. Fuzzy-logic based trajectory generation algorithm is described in second part. Experimental results presented in the third part of the paper prove effectiveness of the proposed method.

  • 산업의 발전에 따라 사회양상도 복잡 다양하게 변화하여 오고 생활의 편리함도 늘어났지만, 그에 따른 화재위험요인도 함께 증가하고 있다. 최근 국내 건축물 환경도 초고층화 인텔리전트(Intelligent)화 되어가면서 화재로 인한 인적 물적 손실은 계속적으로 증가하고 있어 과거보다 화재발생을 줄일 수 있는 제도적 장치를 보완하여야 한다. 본 연구의 목적은 특정소방대상물 관리제도에 대한 전반적인 운영 실태와 문제점을 도출하여 특정소방대상물의 방화관리 등급체계 개선방안을 제시하는데 있다. 개선방안으로는 화재 위험성 평가제도 도입, 가칭 "소방안전공사"의 신설, 특정소방대상물 방화관리등급 재분류, 초고층 및 지하심층 건축물에 방화관리자 신설 등이다.
