  • Grounding electrodes as discharge paths to the earth are normally used to ensure the safety of human body and facilities from the over-voltages in distribution power system, and each grounding mode has a prescribed ground resistance value respectively which is applied by the utilities. As the various electrodes for distribution power system are recently developing to improve the performance of them and resolve the problem of space restriction, it is necessary to measure and investigate the safety of human body of developed electrodes. Therefore, in this paper, we provide briefly a technical comparison of two standards, i.e. IEEE Std 80 and the IEC 479-1, and describe the configuration of safety measurement system which can measure the step voltage and the touch voltage of grounding electrodes based on IEEE Std 80.

  • This study is concerned with the disasters that occure in the field of industrial explosives and analyzed by two side the disaster of the manufacturing factory and that of the field, and is studied about the safety and the countermeasure. The industrial explosives accidents occure just accidentaly and unforeseeable, and reappearance experiments are more difficult. The 3E of J.H. Harvey was applied in this study to establish the counter measure of preventation of accidents, overcoming these restricted factores. As a method of technical safety countermeasures. The blasting vibration formula which had been conformed from the Seoul Subway Construction work during 1980-1984 year, was uilized, and, using the formula $V=Kw^{0.5}D^{-1.5}$ for the gneiss which is widely distributed in Pusan area, an index of the minimum and maximum amount of gun powder, to be used according to safety distance was made, and it helped the gun powder managing technician's practical business. During the fore work discharging, the safety distances of felling were theoretically established based on the writer ${\diagdown}s$ experiences of more than 10 years on this field.

  • This study was to suggest the necessity of depth research in order to enhance the effectiveness of technical consulting system. And the purpose of this study was to decrease the construction accidents to some extent, being on the increase day by day as it takes issue properly and suggest a reform measure. As for research method, it executed the collection of public opinions widely and questionnaire with the bibliography, expert of construction safety, the related institutions, academic world, safety association, and director of construction site. Also, it was to suggest the reform measure by the stage, classifying the problems on the system and operation by 4 stages like a stage of delivery of subscription and supervision, a stage of contract with guidance of technology, a stage of executing the guidance work of technology, and a stage of performance of advice.

  • This study focuses on the evaluation of severity measures used for accidents associated with industrial machines and devices. In particular, duration of medical treatment, duration of work loss, number of deaths in an individual accident associated with industrial machines and devices are evaluated in various ways to assess the severity of the accident. The number of accidents with work loss of longer than 1 year as the severity measure and the number of accidents as the frequency measure appeared to be the most discriminating information and allow risk assessment based on these frequency and severity measures for grouping of industrial machines and devices. Results of such risk assessment further confirmed the re-classification of industrial machines and devices that are currently subject to safety certification (SC) and self-declaration of conformity (SDC) or selection of those machines and devices that are newly subject to SC and SDC.

  • Purpose : This study was performed to develop a scale of outdoor school safety behavior in Korean elementary students. Methods : A list of 40 items were selected by priori experiences of school health teachers and a literature review. For evaluation of the appropriateness of the 32 items, questionnaires were reviewed by an expert group which was consisted of 10 professionals. Validity of the 31 items was screened in this process with 4 point Likert scale. Using the preliminary tool. data were collected from 684 subjects for item analysis and factor analysis. A total of 26 items were remained, and items with the lower than 0.2 item-total correlation coefficient were removed. Factor analysis was done with these 26 items, and 26 items with factor loadings higher or equal to 0.4 were remained. Relsult : 1. Cronbach's alpha for the 26 items was 0.70 2. Five factors were identified with eigen value 1.0 These contributed $51.617\%$ of the variance in the total score. 3. Each factor was labled 'vonobserbance of safety rule', 'good habit for safety', 'careless action', 'lack of safety knowledge', 'injurious action to friend' It is suggested that this scale could be used to measure outdoor school safety behaviors among elementary students in Korea.

  • As the chemical industry becomes more advanced, the awareness of chemical accidents is rising, and legal systems for chemical safety management are strengthened. In this study, quantitative risk assessment of liquid chlorine leak was conducted. Risk assessment was performed in the order of frequency analysis, consequence analysis, and risk calculation. The individual risk was presented in the form of contour lines. The social risk was expressed by the FN curve. The risk of day and night was in an unacceptable area, so it was required to mitigate risk. Therefore in-building, which could trap the pool, was selected as a risk mitigation measure. As a result of the cost benefit analysis, it was concluded that this measure should be reasonably implemented.

  • 본 연구는 종합병원 간호사를 대상으로 환자안전문화에 대한 인식과 안전간호활동에 미치는 영향을 파악하고 변인을 규명하기 위함이다. D시와 G시에 위치한 종합병원의 간호사 178명을 대상으로 하였다. 자료는2015년 6월 20일부터 7월 30일까지 수집하였으며, Kim 등이 수정 보완 한 환자안전문화에 대한 인식과 Lee가 개발한 안전간호활동을 연구도구로 사용하였다. 수집된 자료는 t-test, One-way ANOVA, Pearson correlation coefficients와 단계적 중다회귀분석하였다. 환자안전문화에 대한 인식은 환자안전간호활동과 양의 상관관계가 있었다(r=.407, p<.001) 본 연구 결과 대상자의 병원 근무 환경은 안전간호활동에 43.3%의 영향력이 있는 것으로 나타났으며, 병원간호사의 안전간호활동에 병원근무환경이 가장 중요한 변인으로 볼수 있다. 안전간호의 질 향상을 위하여 환자안전문화에 대한 인식을 높일 수 있는 구체적인 방안과 안전간호 지침이 필요하다.
