This study examined the drinking status to determine the relationship between the AUDIT-K (Alcohol Use Disorders Identification Test-Korean) and job stress of firefighters. The study subject was 267 firefighters in areas C, K, and P, who were surveyed to investigate their drinking status and job stress. According to the study, the AUDIT-K was 152 people (56.9%) in the normal drinking group and 115 people (43.1%) in the problem drinking group. The most frequent answer of the frequency of drinking was 83 people (31.1%) in the 2-4 times of a month; the amount of drinking was 10 cups or more by 101 people (37.8%) in one sitting; the frequency of heavy drinking was every day in 77 people (28.8%). High group of job stress showed a significantly higher odds ratio with the problem drinking group (OR = 5.458, 95% CI = 1.108-26.886). Among them, the interpersonal relation conflict was found to be a major factor affecting AUDIT-K (OR = .332, 95% CI = .134 - .820). Therefore, their AUDIT-K scores can be lowered by reducing the job stress and interpersonal relation conflicts.

PURPOSE: This study examined the actual condition of physical therapy in residential facilities for the disabled and determined the degree of job satisfaction of physical therapists. METHODS: In this study, data were collected using a structured questionnaire targeting 117 physical therapists (male: 49, female: 68) working in residential facilities for the disabled. The questionnaire consisted of 21 items, including six general characteristics, one job satisfaction, and 14 actual situation-related items. RESULTS: The job satisfaction of the physical therapists working in residential facilities for the disabled was 3.81 ± .83, which was between 'normal' and 'satisfactory'. One physical therapist worked in 91.5% of places. The physical therapy room was used only by the physical therapist, occupational therapist or speech therapist, and a nurse and other departments in 65.8%, 9.4%, and 23.1% of cases. On average, six to 10 patients per day were treated the most with 45.3%, followed by physical therapy alone at 19.7%, and work related to medical rehabilitation and other departments at 72.7%. A higher number of overtime hours and nurses resulted in lower job satisfaction. CONCLUSION: The job satisfaction of physical therapists working in residential facilities for the disabled was similar to those of physical therapists working in medical institutions, but the factors affecting the job satisfaction were different. Professionalism in physical therapy was not secured, and the relationships with colleagues were an important factor in increasing job satisfaction.

The percentages of child daycare centers owned by civilians was 52.6%, high school education level was 65.8%, permanent workers was 68.4%, and less than 1 year of foodservice was 34.2%. Average scores of job satisfaction were as follows: working environment scored 20.6 out of 25 points, welfare scored 10.3 out of 15 points, human relationships scored 17.5 out of 20 points, and job-itself scored 13.2 out of 15 points. The lowest job satisfaction average was 'I get paid fairly regarding the working hours and the amount of work' with a score of 3.6 points. Job satisfaction based on facility type, age, education level, and working period did not show significant differences, whereas hired status, numbers of foodservice children, and intention to change jobs showed significant differences. Hired status showed significant differences with welfare satisfaction (P<0.05). Numbers of children showed a significant difference with welfare and human relationship satisfaction (P<0.01, P<0.05).

This paper is meaningful in that it empirically studies the good job condition of which young people think and the impact of job search behavior on employment. In addition, employment status and additional job search performance were set as performance variables. The main research results of this study are as follows. First, as for the good job condition considered by young people, wages and salaries in terms of companies, job stability in terms of environment, and work-life balance in terms of individuals were found. Second, job search behavior was found to be a key variable influencing employment status and job search performance. Third, it was found that job-search stress injures employment. Finally, work experience promotes employment and job search performance. Therefore, to increase the employment success rate of young people, above all, various supports for increasing the frequency of young job seekers' active job search behavior are needed. To this end, it suggests that it is necessary to develop a customized youth policy service model and to provide systematic services to meet the needs of young people.

Purpose: The purpose of this study was to identify health promotion behaviors of elementary school teachers and investigate the factors influencing the health promotion behaviors. Methods: Data were collected from 234 elementary school teachers in the B Metropolitan City Office of Education from 5th to 30th October, 2016. The collected data were analyzed by descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Mann-Whitney test, Kruskal-Wallis test, Spearman correlation coefficient and multiple regression analysis, using SPSS/WIN 23.0. Results: The elementary school teachers' health perception scored 2.94 out of 4, health status 1.59 out of 3, and health promotion behaviors 2.66 out of 4. The level of mental health status (1.67) was higher than that of physical health status (1.54) and the most practiced health promotion behavior was spiritual growth (3.15) and the least was health responsibility (2.00). Significant negative correlations were found between health perception and health status (r=-.59, p<.001) and between health status and health promotion behaviors (r=-.41, p<.001). A significant positive correlation was found between health perception and health promotion behaviors (r=.32, p<.001). The significant factors influencing health promotion behaviors were job stress and health status. These factors explained 19.6% of the health promotion behaviors. Conclusion: It is necessary to establish measures to increase the health perception and health promotion behaviors of elementary school teachers and improve their health status. In addition, since job stress and health status are factors influencing health promotion behaviors, it is necessary to actively manage job stress and health status in order to increase health promotion behaviors.
