Life safety awareness level diagnosis is necessary for customized safety education and continuous safety awareness. As the starting stage of safety education for each life cycle, a scale that has verified the reliability and validity of high school students' life safety awareness has not yet been developed. In this context, the purpose of this study is to develop and validate the life safety awareness scale of high school students and to analyze interindividual differences. Questionnaire data was collected from April to June 2022 from 834 students in the first, second, and third grades of high schools in △△ city in Jeollabuk-do. A final 25-item scale was developed using the preliminary survey, preliminary test, the main test, descriptive statistical analysis, and exploratory and confirmatory factor analysis. This scale consists of four sub-factors: 'safety prevention', 'safety knowledge', 'safety preparation', and 'safety protection'. Good reliability and validity were verified by analysis of content validity and construct validity. The generalizability of the scale was verified by crossover validation between the search group and the crossover group. Based on the interindividual differences analysis, although there was a difference between genders in life safety awareness, there was no difference by grade level and academic achievement. This study is significant in developing the first valid scale that can measure high school students' life safety awareness and providing the necessity and rationale for life safety education by life cycle considering individual gender differences.

Purpose: This study aimed to explore the influences of sense of ethics and attitude toward patient safety in confidence in patient safety in nursing students. Methods: This descriptive study was conducted with 198 students who had clinical practices in two nursing schools. Sense of ethics, attitude and confidence about patient safety were measured by a questionnaire. Data were analyzed with SPSS/WIN 19.0 using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. Results: There were significant differences in satisfaction with nursing major by grade. There were significant positive correlations among sense of ethics, attitude toward patient safety, confidence in patient safety, view on patient's safety, and satisfaction with nursing major. Confidence in patient safety was associated with sense of ethics, attitude toward patient safety, and view on patient's safety, with 37.6% of the variance. Conclusion: The findings suggest that we need to develop curriculums for undergraduate students to improve their sense of ethics and patient safety. Further research is needed to examine educational needs on patient safety in nursing students.

Purpose: An objective of this study was to investigate nurses' perceptions toward patient safety culture and to examine the factors affecting safety care activities. Methods: The participants were 429 nurses, at 6 hospitals located in regions, which have 150 to 300 beds, and HSOPSC (AHRQ, 2009) and questionnaire on safety care activities were used as measurement tools. Descriptive statistics, independent t-test, one way ANOVA, and stepwise multiple regression with SPSS/WIN version12.0 were used to analyze the data. Results: Supervisor manager expectations and actions promoting patients safety and frequency of events reported were the highest as positive responses, whereas staffing and nonpunitive response to errors showed the lowest scores as positive responses. Scores of medication surveillance is the highest while firefighting surveillance is the lowest in terms of safety care activities. Significant predictors influencing safety care activities were frequency of events report, handoffs and transitions, work unit a patient safety grade, organizational learning-continuous improvement, and teamwork across units. These predictors account for 23% of the variance. Conclusion: These results suggest that hospital policies and systems should be built to settle patient safety culture effectively. Development of standard manuals for safety care activities is another critical element for promoting patient safety.

Frozen food processing workers work under a cold environment which can cause several adverse health effects.This study explored factors affecting workers' health in the frozen food industry in Thailand. Participants comprised 497 workers exposed to a cold working environment and 255 office workers who served as the controls. Data were collected by a survey on the work environment, and the interview of workers for abnormal symptoms. The exposed group had the following characteristics: 52.7% male, overall average age of 27 (SD 6.6) years old, attained elementary education (Grade 4 and Grade 6) (54.1%), married (48.9%), smokers (21.3%), alcohol consumption (31.0%), duration of work was between 1 and 5 years (65.2%), working 6 days a week (82.7%), 1-5 hours of overtime per week (33.8%), office workers (33.9%); work category: sizing (6.9%), peeling (28.3%) dissecting (22.2%), and in the warehouse (8.6%). The temperature in the work environment ranged from $17.2^{\circ}C$ to $19.2^{\circ}C$ in most sections, $-18.0^{\circ}C$ in the warehouse, and $25^{\circ}C$ in the office areas. Warehouse workers had more abnormal symptoms than controls including repeated pain in the musculoskeletal system (OR 11.9; 95% CI 6.12-23.45), disturbance throughout the body (OR 4.60; 95% CI 2.00-10.56), respiratory symptoms (OR 9.73; 95% CI 3.53-26.80), episodic finger symptoms (OR 13.51; 95% CI 5.17-35.33). The study results suggest that workers' health should be monitored especially with regard to back and muscle pain, respiratory symptoms, episodic finger symptoms, and cardiovascular symptoms. Health promotion campaigns such as antismoking and reduction of alcohol consumption should be established because smoking and alcohol consumption are contributing factors to the pathogenesis of Raynaud's phenomenon and peripheral vascular disorders such as hypertension and heart disease.

First, according to relations among parameters, educational and cultural activities of four major activities within the dormitory had indirect influences on social activities, eating and sleeping activities had no direct influence on other activities. And social activity had direct influence on the general satisfaction as an important parameter and educational and cultural activities had indirect influence on the whole satisfaction through social activities. Detailed results show that, in the first educational activities directly affecting the lighting and air conditioning facilities (0.22), safety (0.326), Territoriality (0.327), the space density (-0.167), directions (-0.166) and yeohyang having personal characteristics and the safety of the second cultural activities (0.183), Territoriality (0.361), Aesthetics (-0.13) and the personal characteristics Sex (-0.179), the direct effect, third, and erosion has a direct impact on activity The flexibility of the space factor (-0.128) and Territoriality (0.38) and the personal characteristics grade (0.172), respectively. Fourth in social activities directly affecting the pathfinding (-0.104), and parameter, education (0.388) and cultural activities (0.445), and some of the factors affecting the indirect lighting and air conditioning facilities, safety, and Territoriality, the space density, directions, grade, they could influence through educational activities to be analyzed. That is, territoriality in educational function space is the important factor that users react very sensitively in educational, eating and sleeping activities and educational function space must secure area and division considering personal and public use as the space accommodating activity which is lacking in unit residential space. Accordingly, the safety of educational function space in university dormitory is considered as the fundamental safety matter on the fire prevention, hygiene and cleanness for users in the satisfaction of educational and cultural activities.

This study examined the effects of 'Dietary education for children's health UP' (DECHUP) on the changes in knowledge, attitudes, and practice (KAP) of nutrition and food safety in $5^{th}$ grade elementary school students in Incheon. The DECHUP program was conducted from May to October 2018 and consisted of education and activities focusing on the children's levels of understanding. Data were collected before, immediately after, and 6 weeks after DECHUP using the same method. All data were analyzed using SPSS ver 20.0. The level of knowledge and attitudes of the subjects to nutrition and food safety was significantly higher after than before DECHUP, but the attitude of boys did not show any significant difference after 6 weeks. Although there were no significant differences in the behavior for nutrition in the practice of the subjects, there were significant positive changes in the behavior of food safety. The higher the satisfaction of DECHUP, the more positive the change in knowledge, and the more positive the attitude and practice behaviors. Therefore, DECHUP has positive effects on the KAP of the subjects, and it will be helpful for elementary school students to form desirable eating habits if it can be carried out periodically and continuously.
