The current risk assessment system do not reflect workers' various opinion. However, the worker actually are in the center of work field and are exposed to accidents. In this regard, this study suggests enhanced risk assessment by 'safety circle discussion' on workers' hand. The self-administered surveys on supervisors and workers were done for the effect analysis of the safety circle discussion. According to the question investigation, even though the current risk assessment causes difficulties in preventing accidents by unsafe behaviors, the worker-oriented safety circle discussion establishing measures for risk factors of each work type will be able to prevent accidents more effectively. Also, it can positively contribute to safety health awareness, industrial accident prevention, accurate recognition on risk factors, improving safety facilities/work conditions, workers' compliance to safety health rules. Lastly, most respondents agreed that it is necessary to form organic relationship through circle discussion and deriving safety inspections that workers participate.

Estimation of accident costs would set a sound criterion on which invest judgement for work improvement would be decided. Unfortunately, however, the professional agency and most companies in Korea still adopt the conventional cost estimation method based on Heinrich's theory would not be applicable any more since it was developed about a century ago. This research was carried out to confirm the validity of conventional accident cost estimation method. With 110 accident cases occurred in an autoglass manufacturing plant for last 7 years, post-accident treatment procedure was simplified as a model with several phases, and practical costs were analyzed case by case. The results showed that, as expected, the company should the largest portion of loss due to accidents, and that mean indirect cost were 10.10(${\pm}20.70$) times as much as direct cost estimated by conventional method. Therefore, finally, accident types and items influenced much on accidents costs were analyzed and discussed.

To provide tile information ell severe accident progression is very important for advanced or new type of nuclear power plant (NPP) design. A parametric study, therefore was performed to investigate the effect of thermal hydraulic design parameters ell severe accident progression of pressurized water reactors (PWRs), Nine parameters, which are considered important in NPP design or severe accident progression, were selected among the various thermal hydraulic design parameters. The backpropagation neural network (BPN) was used to determine parameters, which might more strongly affect the severe accident progression, among mile parameters. For training. different input patterns were generated by the latin hypercube sampling (LHS) technique and then different target patterns that contain core uncovery time and vessel failure time were obtained for Young Gwang Nuclear (YGN) Units 3&4 using modular accident analysis program (MAAP) 3.0B code. Three different severe accident scenarios, such as two loss of coolant accidents (LOCAs) and station blackout(SBO), were considered in this analysis. Results indicated that design parameters related to refueling water storage tank (RWST), accumulator and steam generator (S/G) have more dominant effects on the progression of severe accidents investigated, compared to tile other six parameters.

The elevator is an essential part of the transportation means in modern society. It has become the convenient movement means of vertical and horizontal mobilities for vulnerable citizens including the disabled or elderly in skyscrapers and the multi-purposes facilities. After the 1990s, the number of newly installed elevators have increased because of the establishment of large scale public houses which need an increase of means of transportation. Thus, the safety accident in the elevator has been currently in an increasing trend as years passed by because that the elevator is always exposed to the risk of accident. Most of the elevator accidents occur in the escalator and moving walkway. This study investigated the current usage situations of users at multi-purpose shopping spaces, the sub way, and the airport about the escalator including moving walkway. Moreover the accident types were analyzed for the escalator based on 10 years of statistics. And the methods for the accident prevention were proposed on the equipment, management and user side.

AR/VR의 발전으로 게임은 내부에서 즐기는 정적인 콘텐츠에서 외부에서 즐기는 동적인 콘텐츠로 확장되었다. 대표적인 AR게임인 'Pokemon Go'는 출시 즉시 신드롬을 만들어내며 닌텐도사의 주가를 120% 상승시켰다. 게임을 통하여 경제적 이익을 얻게 된 사람도 있지만 실제 현장을 방문하는 게임의 형태로 인하여 무단 침입, 교통사고와 같은 새로운 피해사례가 발생하고 있으며 교통사고 건수만 해도 약 11만 4000여건이나 된다. 본 논문에서는 2016년 AR게임 동향을 파악하고 피해 및 긍정사례들을 분석하며, AR게임으로 인한 사고를 예방하는 방법과 비즈니스 모델을 제안한다.

In order to obtain basic reference information for the establishment of effective industrial safety programmes in migrant workers who live in Seoul and Kyungin Area, accident causes were investigated among 210 injured workers. The data were analyzed according to the USA Standards Institute and International Labour Organization method. The results obtained were as follows: 1. The major distribution of national were mostly from china(82.9%), ages are mostly between 30 and 40 years old(32%), and males are more than females, and mostly married. 2. The parts of body most frequently injured were hand and finger, foot and toe, which were 55.3% of total 210 cases. 3. According to the accident type, caught in, under or between were most frequently observed, 40.2% of the total number of injuries. 4. The most responsible source of injuries were power machine, others, moving machine and tool, building construction. 5. According to the unsafe acts, carelessness and unsafety information were most frequently observed, 66.7% of the total number of injuries. 6. There were significantly difference(p<0.05), between type of accident and source of injury, and between working period and unsafe act.

Recently, various types of trains are being operated in the same railroad whose designated stop stations are not the same. In other words, each train does not stop at every station. This could cause the pass-through accidents in which a train passes a station where it is supposed to stop. Although the number of train accidents is on the decrease, this type of error is still an important problem to be resolved. It is true that the burdens of train drivers are growing because the number of high speed trains and non-stop stations is increasing in the current railway system. However, another major reason for this accident is that there is no prevention system for these errors in the current train control system although it is being constantly improved. The purpose of this study is to reinforce the train stop system with wireless communication equipment in order to decrease this type of accident and to maximize the safety of railway transportation.

This paper was carried out to survey fire hazard and improvement at the drain pump in air-conditioners. Based on the results of analysis, the proposal of electrical accidents prevention and a construction improvement are as follows. A power connection of the drain pump has two types, an electrical outlet type and direct connection type at control board of air-conditioner. The electrical outlet types need a bulletin sign or education as malfunction of the drain pump include an additional accidents, current leakage and overflowing with water on the floor from breaker trip by exterior cause and breaker off by mistake of worker. On the other hand, the direct connection types prevent a power interruption as exterior cause, but it has some trouble, cut of ground cable and without protection device. Usually it doesn't work by electrician when air-conditioner and the drain pump power work. Therefore an education or countermeasures are recommended for not electrician. Generally malfunction of the drain pump causes accumulated materials into the tank. Even though the accumulated materials lead to an overheating and burning as failure of detector occur an idling, periodic inspection of the air-conditioner filter and the drain pump tank prevent the trouble.
