Intensity of accidents associated with dangerous machines and devices are (hereafter items), in general, high compared to other industrial accidents. This study focuses on cause analysis of accidents associated with items that are subject to safety certification. The method is based on automated analysis of abstracts of accidents written in descriptive format. The analysis results indicate that more than 50% of accidents associated with items are caused by technical reasons and nearly 50% of accidents were preventable. More effective prevention of industrial accidents would then be realized by safety certification at the stage of danger generation. Transition from the direct regulation on users to manufacturers is also needed to improve the effectiveness and efficiency of industrial safety system in Korea.

In this study, a new technique for detecting near miss using 4M risk assessment method is suggested. Until now, the safety education with instances of near miss has just been progressed in most industrial settings, without any systematic guideline. By menas of appling 4M risk assessment method, the organized technique, which could effectively manage the fundamental prevention of industrial accident in advance, is developed. The organized technique of near miss-management suggested in this study will take an effective role in basically expanding the application of risk assessment method, as well as in contributing the activity of zero-accident as a safety guideline in hazardous workshops.

Foodborne diseases are serious problems throughout the world, because new pathogens have emerged. Nowadays many students eat school lunch provided by school lunch provided by school lunch program. They are threatened by pathogens transmitted by foods. many school children became victims of foodborne diseases. Most foodborne outbreaks were caused by mishandling foods at food service establishments. Food safety practices of school lunch programs in foreign countries were reviewed. Temperature control is the most critical part of keeping the foods safe. In order to prevent foodbrorne diseases in schools, the managers in charge of school lunch program and officials in charge of food safety of local health department try to make sure that foods are out of danger zone of temperature. Prevention of cross contamination, and sanitization of raw foods and utensils are also emphasized by school lunch program managers and health officials.

This study is intended to suggest some ideal measures available in the course of construction from the viewpoint of an architect to reduce damage of human lives and Properties caused by fire accidents in buildings. For this study, 7 buildings burnt by conflaguration in Seoul during the years of 1985 and 1987 are picked up, and 105 withnesses, who were present in one of them at them at fire, are traced for personal interview and respones to the written questionaire about 5 main issues; their perceptional behaviour, their emotional state at that time, their reactions to avoid danger, their escape routes, and their usual awareness to prevent fire. Some desirable measures suggested here are ;making Provisions to install fire centers in large buildings and underground structures in the fire fighting law, and requlating to compose fire units appropriate to the quantity of combustibles inside, limit the length of a blind corridor, furnish balustrade, and limit the width of the landing of the stairs in building code and regulations. Such measures should be considered from the time of planning to construct a building, and some drill and education in fire prevention is demanded for the occupants of the buildings too.

The central burst defects, so-called chevroning, in wire drawing are analyzed by the rigid-plastic finite element method. The occurrence of central burst defects in wire drawing is estimated by the distribution of the hydrostatic pressure around the central part of the workpiece. It has been possible to obtain numerical boundaries which, in reduction in area vs. semicone angle plane, divide the safe and the danger zones, depending on friction factors and material properties. Based on the results of the analysis, it is suggested that the previous criterion derived from the upper bound analysis should be modified for better prediction of the defects. The back tension and the billet with a spherical hole on the central axis are also included in the analysis of the defects.

Many posters and advertisements for fire prevention have long been known to warn of the danger of fire. The reason for this warning is that the damage of the fire is large. In addition, if the second damage occurs, the damage will be larger. In this study, we will design an automatic power circuit breaker that automatically cuts off the power if the temperature sensor is set to a certain temperature value and then goes up above that value. This study will minimize the secondary damage of fire.

Recently, a building fire has occurred due to various influences. Accordingly, we are developing an public safety & security unmanned aerial vehicle for fire prevention and initial response to fire. The public safety & security unmanned aerial vehicle is used to grasp the traffic route to enter the fire engine in the event of a fire in a dense structure and to determine the scale of the fire and the area of danger of collapse around the fire site. In this study, an environmental test of the public safety & security unmanned aerial vehicle's heat resistance was performed in an environment simulating a fire scene.

This paper describes Web-based information sharing mechanism in our hazard map creation support system. This system aims at collecting the unique information received from residents and raising resident's consciousness to disasters by recording hazardous locations where residents feel danger in case of disasters. We have implemented a mechanism to share and integrate data of each terminal through a Web server. We expect that this information sharing effects scalability and usefulness of our system by utilizing collected local hazard information of each district.

In the past most major accidents resulted in death, but today there is a dramatic increase in the number of people who survive such accidents but who are left with permanent injury. Particularly, children who are inquisitive about their surroundings but immature in their ability to assess danger, are more vulnerable to accidents and their causes as well as to determine attitudes towards prevention. The main objective of the study was to assess the effectiveness of using an accident prevention manual for accident for accident prevention education. The study was a quasi-experimental study using a questionnaire format. The subjects of the study were 393 mothers of children attending six day care centers in Seoul. Data collection was done between May 1 and June 15, 1997. The tools used for the study were a questionnaire developed the researchers and a manual for accident prevention. The collected data were analyzed using SPSS. The results of the study are as follows: 1. Types of accidents included stabbing, bums, falls from heights, choking, falls on slippery surfaces, traffic accidents, drowning, poisoning, and electrical shock in that order of frequency. 2. The main causes of accidents in children were from cosmetics and household medications. 3. The most frequent locations of accidents in the home were the bathroom, kitchen, and stairways in that order. 4. For $90.4\%$ of children safety seats were not used when the ridding in a car. 5. In examining the parents' accident prevention practices, it was found that many parents used only . one electrical outlet for many appliances, tending to overload the electricity lines and that they were not practically concerned bout the flammability of children's pajamas, indicating a less than positive attitude towards fire prevention. 6. The parents had not provided their children with any instruction on accident prevention or on what to do after an accident had occurred. 7. After the use of pamphlet in an accident prevention education program, it was found that there was a statistically significant difference in the degree to which children carried out safety measures (t=14.96, p=.000) and in their safety habits (t=-1.67, p<.1) indicating an effectiveness in this method of education. The results of this study showed that there are many things in a child's environment that can cause accidents and that the possibility of an accident occurring is high. So nurses looking after children should be aware of the need for safety education to prevent accidents in the home and plan to provide appropriate educational material to help parents with this education.
