The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization's safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.

Purpose: The purpose of this study was to identify the factors affecting the perceptions of patient safety culture, safety care knowledge, and safety care activity among nurses at orthopedic hospitals. Methods: Data were collected during Feb. 16 and Feb. 26, 2017, from 195 nurses of 9 small to medium sized orthopedic hospitals. Questionnaires about patient safety culture, safety care knowledge and activity were used. Data were analyzed by descriptive statistics, t-test, ANOVA, $Scheff\acute{e}$ test, Pearson's correlation coefficient, and stepwise multiple regression. Results: The safety care activity was positively correlated with perceptions of patient safety culture (r=.50, p<.001) and knowledge (r=.48, p<.001). Factors that had influence on the safety care activity were the patient safety culture (${\beta}=.30$, p<.001), age (${\beta}=.27$, p<.001), and knowledge of the safety activity (${\beta}=.21$, p=.004). The patient safety care activity was explained 36.6% by those factors. Conclusion: To enhance the patient safety care activity, it should be provided the environment and open communication for the perceptions of patient safety culture and the in service education program for safety care knowledge.

Objectives: There have been no specific as well as evidence-based physical activity guidelines issued on the governmental level. There just have been physical activity recommendations and guidelines released from governmental agencies or organizations as well as individual researchers and these are not consistent, thereby giving the public and even some professionals quite a confusion. As such, this study was aimed to suggest key factors to include when issuing national physical activity recommendations for Koreans. Methods: Since chronological evolution of modern physical activity recommendations reflects key factors to consider when establishing those recommendations and guidelines, that released for several decades was reviewed. Results: The evolution was found to be based on the basis of strong evidence from both epidemiological and exercise physiology studies and the key concepts of such evolution were feasibility, efficacy, and safety. Conclusion: On the basis of three key factors found in the review process, this study concluded that the upcoming national physical activity guidelines should include the following to maximize the outcomes of the efforts which have long been put by the division of physical activity under the 'New Health Plan 2010'. First, guidelines for achieving health benefits (ie, preventing chronic diseases such as cardiovascular disease, diabetes, and cancers or weight management) as well as improving cardiorespiratory fitness should be included to enhance efficacy. Second, safety measures should be included to enhance safety. Third, various alternative forms of physical activity should be included to enhance feasibility.

Background: Online teaching and learning extend the duration of using gadgets such as mobile phones and tablets. A prolonged usage of these gadgets in a static position can lead to musculoskeletal disorders (MSD). Therefore, this study aims to identify the risk factors related to musculoskeletal symptoms while using gadgets during work from home due to the COVID-19 pandemic. Method: A cross-sectional survey with online-based questionnaires was collected from the University of Indonesia, consisting of lecturers, students, and managerial staff. The minimum number of respondents was 1,080 and was defined by stratified random sampling. Furthermore, the dependent variable was musculoskeletal symptoms, while the independent were age, gender, job position, duration, activity when using gadgets, and how to hold them. Result: Most of the respondents had mobile phones but only 16% had tablets. Furthermore, about 56.7% have used a mobile phone for more than 10 years, while about 89.7% have used a tablet for less than 10 years. A multivariate analysis found factors that were significantly associated with MSD symptoms while using a mobile phone, such as age, gender, web browsing activity, work, or college activities. These activities include doing assignments and holding the phone with two hands with two thumbs actively operating. The factors that were significantly associated with MSD symptoms when using tablets were gender, academic position, social media activity, and placing the tablet on a table with two actively working index fingers. Conclusion: Therefore, from the results of this study it is necessary to have WFH and e-learning policies to reduce MSD symptoms and enhance productivity at work.

This paper surveys and researches primary school students' situation of their school life. The purpose of this paper is to propose the basic information of the accident prevention teaching and the safety management in order to avoid accidents to occur beforehand. We selected m primary students out of the six primary schools in Taebaek City at which the nursing students of Kangwon Tourism College practiced school health. We used SPSS Win for analyzing data. We carne up with the general characteristics and percentage using frequency analysis, mean and standard deviation of each item, the mean difference using T-Test, and the different factors using one-way analysis. The results are as follows: 1. The 6th grade students don't practice safety procedures than the 5th grade students during outside the school. The older the student is, the less it practices safety procedures. 2. Boys practice safety procedures better than the girls during inside and outside the school. 3. Hot -tempered students don't practice safety procedures properly. 4. Most of the students who often use the health room of the school have high scores in safety procedures test and as a result, these students practice safety procedures thoroughly. 5. The grade of safety living activity is the highest during gymnastic class. Next is when the students use the stairs when they are going up and clown. Then, the use of science room In the playground is the lowest grade of safety for living activity.

Screening of estrogenic activity on dichloro diphenyl trichloroethane (DDT), dichloro diphenyl dichloro ethylene (DDE), dieldrin, heptachlor, aldrin, chlordane, lindane, polybrominated diphenyl ethers (PBDE) and parabens was compared using Organization for Economic Cooperation and Development (OECD) test guideline 455 (TG455). The estrogenic activity of DDT was 58,000-fold ($PC_{50}$, $1.67{\times}10^{-6}$ M) less than $17{\beta}$-estradiol($E_2$) ($PC_{50}$, $2.88{\times}10^{-11}$ M) but DDE, dieldrin, heptachlor, aldrin, chlordane, lindane and PBDE did not show any estrogenic activity in this assay system. In the case of paraben compounds, the rank of relative transcriptional activation (logRTA) was butyl paraben -1.63752 ($PC_{50}$, $1.25{\times}10^{-7}$ M) > isobutyl paraben -2.34008 ($PC_{50}$, $6.3{\times}10^{-7}$ M) > ethyl paraben -2.64016 ($PC_{50}$, $1.26{\times}10^{-6}$ M) > isopropyl paraben -2.73993 ($PC_{50}$, $1.58{\times}10^{-6}$ M) > propyl paraben -2.84164 ($PC_{50}$, $2.0{\times}10^{-6}$ M). Our data suggest that OECD test guideline TG455 may be useful as a screening tool for potential endocrine disruptors.

Scientific exploration of how occupational health risks relate with occupational illnesses are essential for mitigating health-related issues in industries. This study analyzed the risk scores obtained by occupational health risk assessments at 3,172 manufacturing companies and examined their effects on occupational illness. Statistical analyses revealed that companies with an occupational health manager (scored 89.1 out of 100) had significantly higher activity scores of health management compared to those without (78.2). However, companies with a history of occupational illness (79.1) or those classified as high-risk industries (85.2) had significantly lower activity scores than their counterparts (81.7, 87.3). In addition, regression analyses using factor analysis showed that latent risk factors such as cardiovascular disease/job stress, health management, and musculoskeletal problem significantly influenced the risk of occupational illness. The activity factors such as health management, work environment management, and regulatory complaisance significant impacted the reduction of occupational illness. The findings of this study can be used to improve the occupational health risk assessment method and utilized in effectively managing occupational risks in industries.

The study aimed to investigate the influence of perceived patient safety culture on patient safety management activity in the dental hygienists. Methods: A self-reported questionnaire was completed by 292 dental hygienists in Seoul, Incheon and Gyeonggido from March 1 to April 8, 2016. The questionnaire consisted of general characteristics of the subjects (9 items), patient safety culture (44 items), and patient safety management activity (25 items) by Likert 5 point scale. Data were analyzed by t test, one way ANOVA, stepwise multiple regression test, and post-hoc Tukey test using SPSS 18.0 program. Results: The perceived patient safety culture was 3.50 on average. Entire organization was the highest score (3.68) and followed the communication process (3.55), the environment of work unit (3.47), the attitude of supervisor/manager (3.45), and the frequency of events reported (2.98). The average of patient safety management activity was 3.71. As for the factors of patient safety culture on patient safety management activity, communication process was the most influential factor (${\beta}=0.268$), and followed the entire organization (${\beta}=0.265$), the environment of work unit (${\beta} =0.166$), the frequency of events reported (${\beta}=0.104$), and among the control variables. Work place proved to be the only significant variable. Conclusions: In order to promote patient safety management activity of dental institutions, the patient safety culture should be created and established. The influence of communication process and patient safety culture at entire organization level was huge. So the environment of work unit and the perceived patient safety culture in the process of reported events were influencing factors. The strategy for patient safety management activity should be considered because of low level of perceived patient safety culture.

Objectives: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. Methods: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ${\geq}5$ for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. Results: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ${\geq}30$). Mean BMI increased with increasing psychological distress (no distress, BMI = $27.2kg/m^2$; mild distress, $27.6kg/m^2$; and moderate/high distress, $33.1kg/m^2$; p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI ($30.3kg/m^2$ for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. Conclusion: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association.
