한국에 만연하는 불신 중 가장 두드러진 것 중의 하나가 수돗물이 아닐까 싶다. 정부나 지자체에서 수돗물이 안전하니 안심하고 마시라고 해도 굳이 비싼 정수기를 사용하거나 생수를 사 마시고 있다. 한국과 같이 투명하게 수질평가위원의 참석 하에 시료를 채취하고 제 3기관에 의뢰하여 분석을 하며 이것을 공개하는 곳은 거의 없다. 그런데도 일반 국민들은 아직도 수질검사를 속인다거나 평가위원들도 다 같은 부류의 사람들이라고 오해하는 분위기가 팽배한 것 같다.

Many researchers in South Korea have conducted regarding the safety climate and concluded that the safety climate effect on the safety performance. However, the survey tools that were used in domestic research were developed by individuals or designed by reconstituting, translating from previous studies. In addition, the safety climate as a low factor of organizational culture showed up in different types depending on business scale. In order to solve this issue, the objective of this study is to analyze the safety climate level of construction company depending on business scale in South Korea. first, the survey is conducted by NOSACQ-50 for construction workers. Second, it is analyzed how organizational culture affected the safety climate. Finally, the improvements are suggested on the level of safety climate. In the future, this study will be used as a baseline for the effects of the safety climate on the safety performance in construction site based on business scale.

This paper reviewed the relationship between safety climate(management commitment, safety education, preventive activity) and safety participation, and the mediating effect of safety motivation(intrinsic and extrinsic motivation) in small business employee. Based on the responses from 270 employees, the results of multiple regression analysis appeared as follow; 1) management commitment, safety education, and preventive activity effect positively on intrinsic/extrinsic safety motivation. 2) management commitment, safety education, and preventive activity effect positively on safety participation. 3) intrinsic and extrinsic safety motivation effect positively on safety participation. 4) intrinsic safety motivation mediates between 3 climate factors(management commitment, safety education, preventive activity) and safety participation. 5) extrinsic safety motivation mediates between only management commitment and safety participation.

Purpose: This study aimed to examine the relationship between organizational health (OH), safety climate (SC), the nursing working environment (NWE), and engagement in patient safety management activities (PSMA) among operating room nurses and identify the factors that predict engagement in PSMA. Methods: From August 10th to 25th, 2018, 176 operating room nurses who were working in tertiary and general hospitals responded to a structured questionnaire. Using SPSS/WIN 25.0, the collected data were subjected to independent-samples t-test, one-way analysis of variance, Scheffe?test, and Pearson's correlational and multiple stepwise regression analyses. Results: OH and SC were significantly correlated with engagement in PSMA. The factors that predicted engagement in PSMA were OH, NWE, participation in accreditation, years of work experience, and hospital size; together, they explained 17% of the variance in engagement in PSMA. Conclusion: This study revealed that OH has a significant influence on engagement in PSMA among operating room nurses. Therefore, hospitals should aim to create healthy working environments to promote engagement in PSMA among operating room nurses, actively delegate responsibilities to increase their level of participation in accreditation, and implement strategies that maintain high levels of nurse retention.

While the hydrogen refueling station is rapidly expanded and installed, the safety inspection of the hydrogen pressure vessel in the station should be very important. Of these, according to ASME, hydrogen embrittlement tests must be performed for hydrogen vessel that store hydrogen above a certain pressure. The main test method for hydrogen embrittlement inspection is to carry out fracture tests and fatigue fracture tests in a high pressure hydrogen atmosphere, which allows the durability limit of the pressure vessel to be measured and the endurable limit to be determined in the hydrogen atmosphere. In detail, the critical crack depth can be calculated by the stress intensity factor(K), and the service life can be determined by da/dN (fatigue growth rate). API579-1/ ASME FFS-1 part 9 exemplifies the calculation method according to the mode of crack-like flaws, but for various shapes such as plates and cylinders, there are about 55 modes according to the shape and location of the crack. Due to the fairly complex formula, it is not easily accessible. In this study, we will show you how to calculate fracture mechanics numerically via Excel and VBA. In addition, this was applied to analyze the effects of the thickness and inner diameter of the pressure vessel on the service life.

The purpose of this study is to evaluate the actual conditions of peer victimization and to examine how the various factors of school climate influence peer victimization. Analysis on the relationship between various school climate and peer victimization has not been yet dealt with in Korea. Participants in this study were middle school students chosen from 11 middle schools in Seoul, by convenience sampling. A total of 1,204 surveys were then analyzed. Methods for analysis included Frequencies, Descriptives, Pearson's Correlation, Hierarchical Regression. From the result of the analysis, the level of verbal violence came out to be a relatively high form of peer victimization. The hierarchical regression were conducted in two steps. The second model's descriptive variable was higher by 19.6% than the first model. The variables of interaction between teacher and student in peer violence(${\beta}=.130$), of school facility maintenance(${\beta}=.067$), of safety of school environment(${\beta}=.331$), and economic status and sex out of controlled variables were proved to be of significance, and those variables explained 23.0% of the entire model. Based on the results of this study, practical and effective policy solutions to improve the school climate better have been suggested.

순수한 우라늄 금속은 칩이나 분말로 존재할 경우 반응면적이 넓어 자연 발화할 정도의 산화력을 지니며 산화열이 높기 때문에 운반 및 처리시 화재의 위험성이 있다. 따라서 이들을 장기보관하거나 영구처분시 안정한 형태의 전환이 우선되어야 한다. 외국의 경우 감손우라늄 폐기물을 자연에서 가장 안전한 상태인 산화우라늄의 형태로 산화 처리 후 영구처분하고 있으며, 이를 위하여 우라늄 칩의 산화거동에 관한 연구가 수행 되었다. 우라늄 칩을 안전하게 보관하려면 불활성 분위기를 형성해 주든가 또는 우라늄 칩의 표면에 부동태층을 형성시켜야 한다. 또는 우라늄 칩을 광유속에 넣어 공기나 물이 우라늄 칩에 접촉되지 않는 방법으로 보관하는 것이 바람직하다.

석유화학플랜트에서 운용되는 반응로, 저장탱크, 열교환기 등의 압력용기 그리고 배관 등의 시 설물은 장기간 사용함에 따라 고온, 고압, 부식성 분위기, 열응력, 피로 등 여러 가지 요인으로 경년열화되어 노후화 된다. 일반적으로 이들 설비들에서 작용하는 유체나 가스의 누출은 화재나 폭발과 같은 재해 뿐만아니라 주위 환경을 오염시켜 공해를 유발하게 되며, 이들 시설물에 대한 신뢰성 및 안전성 확보는 국가기간 산업에서 매우 중요하며 이와 관련된 장치의 설계, 시공 뿐만 아니라 시험검사 및 평가기술 측면에서도 중요시되고 있다. 플랜트 시설물에 대한 가동중 주기적인 안전진단은 현상의 파악 뿐만 아니라 인명과 재산의 손실을 미연에 예방하고 경제적 이고 효율적인 운영계획 수립에 필수적인 것이다. 이 글에서는 국내 석유화학플랜트의 검사현 황을 알아보고 앞으로 플랜트의 효율적 운영 및 안전 운전을 위한 가동중검사 기술 및 개선대 책에 대하여 기술하고자 한다.

Since Zohar(1980) emphasized the influence of social, organizational, and psychological context in occupational safety and health study, the research in this area tends to be emphasizing the influences of personal and physical interaction. With this research trend, this paper is to examine the relationship between safety climate model and safety accident, and the interactional or moderating effect of personal and physical factor on the above relationship. Author conducted a survey to 292 manufacturing workers in construction industry, and the chief results of statistical analysis are as follows 1) management involvement, safety education, precaution activities, and safety system have negative effects on safety accident, 2) a-type personality has interactional effect on safety accident with communication, precaution activities, and safety system. 3) physical job load has interactional effect on safety accident with precaution activities, and safety system.

Safety climate in the research area of industrial safety begins to be influential meta-theory. With this research trend, this paper is to examine the relationship between safety climate and safety participation, and the moderating effect of age. Data were gathered from 292 manufacturing workers in construction industry. It is found that management involvement, safety education, and precaution activities have affirmative effect on safety participation, and physical job load negative effect on it. Next, education, precaution activities, and safety system were found to have interactional effects on safety participation with age.
