Laboratory experiments and point monitoring of reservoir sediments have proven that stable sulfate reduction (SSR) can lower the concentrations of toxic metals and sulfate in acidic groundwater for a long time. Here, we hypothesize that SSR occurred during in situ leaching after uranium mining, which can impact the fate of acid groundwater in an entire region. To test this, we applied a sulfur isotope fractionation method to analyze the mechanism for natural attenuation of contaminated groundwater produced by acid in situ leaching of uranium (Xinjiang, China). The results showed that δ³⁴S increased over time after the cessation of uranium mining, and natural attenuation caused considerable, area-scale immobilization of sulfur corresponding to retention levels of 5.3%-48.3% while simultaneously decreasing the concentration of uranium. Isotopic evidence for SSR in the area, together with evidence for changes of pollutant concentrations, suggest that area-scale SSR is most likely also important at other acid mining sites for uranium, where retention of acid groundwater may be strengthened through natural attenuation. To recapitulate, the sulfur isotope fractionation method constitutes a relatively accurate tool for quantification of spatiotemporal trends for groundwater during migration and transformation resulting from acid in situ leaching of uranium in northern China.

Background & Objectives: International radiation protection committee recognized the importance of radiation protection from medical practices because the exposure to the radiation in medical practice is higher than any other exposure. The factors on knowledge, attitude and practice of radiation safety of the medical workers engaged in radiation were analyzed in order to improve radiation safety technology. Method: Questionnaires were used for 1200 radiation workers in medical institution from July 23 through September 4 and collected for analysis. Results: Different level of safety measures were practiced by age, marital status, career, and medical facility. The difference was statistically significant. Higher levels of safety measures were practiced in the age group of 50s and married persons. The workers who have more than 20 years experience have higher level of safety measures. The workers of health centers have higher level of safety measures to compare with other workers. The factors which give more concerns on safety practice were self efficacy, practice and knowledge in order. Conclusion: Safety conscious operators should get additional education program to maintain higher level of safety. The operators who do not have much safety concern should be intensive training program for self efficacy and safety.

Background: The purpose of this study was to examine undergraduate medical students' perceptions and intentions regarding patient safety during clinical clerkships. Methods: Cross-sectional and self-administered questionnaire survey was conducted on 34 students from one medical school using a modified version of the Medical Student Safety Attitudes and Professionalism Survey (MSSAPS). We assessed $4^{rd}-year$ medical students' perceptions of the cultures ('safety', 'teamwork', and 'error disclosure'), 'behavioural intentions' concerning patient safety issues and 'overall patient safety'. The overall response rate was 66.4%. Results: Among safety domains, "teamwork culture" was rated highest. "Error disclosure culture" received the lowest ratings. Regarding the error disclosure domain, only 10% of respondents reported that they have received education or training on how to disclose medical error to patients. Independent of survey domains, when students were asked "Overall, do you think your hospital is safe based on your clinical rotation?", 61.8% reported that the hospital was safe. Conclusions: Assessing students' perceptions of safety culture can provide clerkship directors and educators with information that enhances the educational environment and promotes patient safety. Discussions of medical errors, patient safety, and how best to incorporate an analysis of these issues into the existing curriculum are needed.

Background: By examining the safety issues involved in on-site training sessions conducted at specialized vocational high schools, and by analyzing the effects of non-destructive testing (NDT) safety training, this study aims to contribute to ensuring the general safety of high school students. Materials and Methods: Students who expressed an interest in participation were surveyed regarding current NDT training practices, as well as NDT safety training. A total of 361 students from 4 schools participated in this study; 37.7% (136 students) were from the Seoul metropolitan area and 62.3% (225 students) were from other areas. Results and Discussion: Of the respondents, 2.2% (8 students) reported having engaged in NDT. As a result of safety training, statistically significant improvements were observed in most areas, except for individuals with previous NDT experience. The areas of improvement included safety awareness, acquisition of knowledge, subjective knowledge levels, objective knowledge levels, and adjustments to existing personal attitudes. Conclusion: Even at absolutely necessary observation-only training sessions, it is crucial that sufficient safety training and additional safety measures be adequately provided.

This study was carried out to investigate the children's knowledge, attitudes and practices of food safety. A total of 355 data were collected from elementary school students. The concern of food safety was moderate in 5 point Likert scale and relatively high correlated with food safety knowledge(r=0.571) and education(r=0.534). The experience and knowledge of terminology on food safety were estimated. The level of food safety was classified into 5 groups and the consideration of food purchase was classified into 3 groups by factor analysis. A few children were aware of the food safety knowledge and could hardly understood English terminology. And the food safety practices were surveyed, and most of children checked with expiration dates and packaging conditions of food. Personal hygiene practice of children was significantly affected by gender, self hygiene evaluation and the knowledge level of food safety. Providing more food safety information affects personal hygiene and the practices of food purchase, so educational programs on food safety for children were required.

The purpose of this study is to investigate the perception of fire safety education in middle and high school teachers. The results of this study provide basic data necessary for future school safety education. The research was carried out using a questionnaire given to 317 school teachers. The frequency of the questionnaire was calculated from frequency analysis using SPSS version 19.0. A chi-square test was conducted to verify the analyzed questionnaire data. Cronbach's alpha for fire safety awareness in the respondents is 0.845, which is very reliable. According to the results of the survey, fire safety education currently conducted in schools is aimed at having a safe lifestyle and respect for life. The training is conducted once every six months, on average, and training time is 30 to 45 minutes. Fire safety education in schools is conducted in the form of experience-oriented education in cooperation with fire-related organizations following the plan of the school. Educational texts are used and utilized through the Internet and in related publications. Under the present circumstances, it is necessary to secure sufficient space to run an experience-related education program and to actively participate in the students' fire safety education at the school.

Purpose : The aim of this article is to describe the nurses' experiential learning mechanism on patient safety. Methods : To analyze nurses' learning experiences on patient safety cases, a focus-group interview method was used. The Kolb's experiential learning model was used as a reference model. Findings : Without deep reflective reasoning about specific experiences, there is no creative or innovative solutions to experiment actively. Nurses are likely to be reluctant learners when there is no systemic support from formal departments which is in charge of patient safety and quality of care. Conclusion : In order to build patient safety culture in hospital, there should be efforts to make nurses as active learners on patient safety as well as to build learning environments in medical units.
