  • A railway security detection system is very important. There are many safety factors that directly affect the safe operation of trains. Security detection technology can be divided into passive and active approaches. In this paper, we will first survey the railway security systems and compare them. We will also propose a subway security detection system with computer vision technology, which can detect three kinds of problems: the spark problem, the obstacle problem, and the lost screw problem. The spark and obstacle detection methods are unique in our system. In our experiment using about 900 input test images, we obtained about a 99.8% performance in F- measure for the spark detection problem, and about 94.7% for the obstacle detection problem.

  • This study dealed with problem to estimate the uniformity of dust clouds, as a fundamental study to estimate the ignition hazardous evaluation of hybrid mixtures. The developed method was proposed to grasp space distribution of dusts, and also, an experimental apparatus considering with dispersion and reproduction of dusts were uniquely devised and studied.

  • Biotechnology has reached the level of giving birth to new forms of life and with this is a growing controversy in the conflict between science and ethics. Especially, GMOs are closely linked to the food products we consume and thus, the majority of the public shows a very sensitive reaction to the safety of GMO food products. Many perspectives arose surrounding the issues of safety on the human body and the ecology. This outlines diverse structural mechanisms to be set up to ensure safety such as risk assessment, risk management etc. Despite the precautionary principle guaranteed in many ways, the problem arises whether and how this principle can be taken in the safety assessment. GMOs due to its uniqueness do not end with just the possession of the technology involved but must also be considered with the prerequisite that they could be cultured again. Therefore the reinforcement of safety assessment system is necessary. That is, the reinforcement of risk assessment including field tests, the consideration of socio-economic effects, the coordinated system of relevant authorities, the development of technology for safety assessment.

  • For advanced construction safety, it is able to valanced control that are 'Enforcement', 'Engineering', 'Education'. It is central to an existing builders, that system problem about safety management is converted to a substantial and sensible system. Also, participates who are a governments, builders, designers, architects, supervisors with reference to construction project are developed labor saving technique for total system that is included planing, drawing, building, maintaining. And, it is to develop a program what is able to participate in an industry, a school, and an institute with governments that is for training professional for construction safety technique.

  • Safety management cost, $US\$$ one thousand billion has been input to the construction area from 1995 to 2000 but the management quality is still in the developing country level. The above mentioned increase of accident rate are attributed to the generous code regulation, net fit to the sense, varying with time change, but the more fundamental reason of this is no practical construction safety management system, up to now. Hardware-orienting operation for the system could be a main reason of this problem. In this paper, we developed a model for efficient construction safety system. It was found from the case study that the A Study on Introduction Application of Occupational Health & Safety Management System for Construction Industry.

  • Construction accidents occur reiteratively in similar fashions. There have been several attempts to develop a safety program for preventing construction accidents on sites. It will be very effective to use previous accident cases for establishing proper safety plan and managing safety process. This research develops a case-based construction safety management system which enables construction managers or safety managers to prevent potential accidents during the construction process. The case-oriented approach is performed through the representation of previous accident cases in accordant with the similarity to the conditions of current site. It uses a case-based reasoning which is one of the reasoning methods of an expert system. A prototype system for the reasoning model was implemented using one of the case based system development tools. The system was applied to a real construction site to verify its capability and validity. It was founded that the causes of accidents were successfully removed, so the proposed model proved to be reasonable. Additional research is needed to resolve the technical problem how to adapt the countermeasures for accident prevention provided by the reasoning model.

  • The problem of establishing weapon system safety especially during the development process has been one of the very important fields related with public safety in advanced countries such as USA, UK and so on. These countries have launched strong policies on system safety to reduce the chance of accidents. However, the Republic of Korea (ROK) has limited experiences and application of the system safety on domestically produced weapon systems. Therefore, it is imperative that the government starts a comprehensive and systematic policy on system safety to reduce the occurrence of potential accidents during the development of weapon systems. In this paper, we analyze system-level activities needed through the life-cycle of the weapon systems and provide a suggestion for application of the system safety.

  • The gang-form widely used in apartment construction sites has advantages compared to scaffolding in preventing falling accidents. One problem, however, is that safety accidents associated with gang-form works repeatedly occur due to worker carelessness. In this study, hierarchical checking tables are provided to support safety management activities for the gang-form works at the sites. Through a survey of experts and analyses of case studies of construction accidents, 137 safety check items are classified by participant type based on a hierarchical safety check scheme. The applicability and effectiveness of the hierarchical checking tables was evaluated through interviews with experts. It was found that the hierarchical checking tables enabled each gang-form related participant to check his own safety management items, and provided a level-wise structure to site safety management systems.

  • Since the introduction of product liability law from America in 1960s, product liability has been on the rise as an important problem to the quality management of company and consumer's safety. Together with this, before the legislation of product liability system in Korea, the sense and level of company and consumer about product safety are rapidly changing, In times like the present, ensuring more systematic product safety and consumer safety, and the buildup need of competitive power in accordance with product liability prevention of company grows raising. Therefore, this study presents the most effectively manageable ways of product liability the side of safety management of consumers and companies through the ensuring ways and activity models of product safety and certification system in company.
