Objectives: The objectives of the study were to investigate the school nutrition teachers' perception on their job and to find out recommendations needed for its improvement in order to provide a quality foodservice and nutrition education at schools. Methods: A total of 219 school nutrition teachers in Seoul were surveyed using selfadministered questionnaires. Results: The perceived importance of the 16 job duties was rated 3.8 based on a 5-point scale (1: very unimportant - 5: very important). The importance of six duties including nutrition management, production management, nutrition education, and food safety management were rated over 4 point but that of record-keeping for documents, official reporting, and service management was rated the lowest. Importance-Performance Analysis showed that nutrition management, receiving/storage management, production management, menu management, food safety management, and equipment/facilities management should be emphasized to maintain the current performance of duties. The performance of the nutrition education and counseling needed to be improved since the importance scores were greater than average but the performance scores were lower than the average. Official reporting and miscellaneous jobs were rated the highest for simplification need. More than half of the respondents agreed that equipment/facilities management, miscellaneous jobs, service staff supervision, and service line supervision could be allocated to other school departments. Conclusions: School nutrition teachers should invest more time and resources on their core job duties such as nutrition management, production management, food safety management, and nutrition education for providing quality foodservice and nutrition education. To reflect the environmental changes of school foodservice, a reasonable staffing index of school nutrition teachers needs to be developed. In addition, hiring an assistant or implementing school nutrition teacher internship programs can be useful to reduce workloads of the nutrition teachers.

Background: Gig workers, also known as platform workers, are independent workers who are not employed by any particular company. The number of gig economy workers has rapidly increased worldwide in the past decade. There is a dearth of occupational health studies among gig economy workers. We aimed to investigate the association between exposure to violence and job stress in gig economy workers and depressive symptoms. Methods: A total of 955 individuals (521 gig workers and 434 general workers) participated in this study and variables were measured through self-report questionnaires. Depressive symptoms were evaluated by the Patient Health Questionnaire-9 when the score was greater than or equal to 10 points. The odds ratio with 95% confidence interval was calculated using multivariable logistic regression adjusted for age, sex, working hours, education level, exposure to violence and job stress. Results: 19% of gig economy workers reported depressive symptoms, while only 11% of general workers reported the depressive symptoms. In association to depressive symptoms among gig economy workers, the mainly result of odds ratios for depressive symptoms were as follows: 1.81 for workers type, 3.53 for humiliating treatment, 2.65 for sexual harassment, 3.55 for less than three meals per day, 3.69 for feeling too tired to do housework after leaving work. Conclusions: Gig economic workers are exposed to violence and job stress in the workplace more than general workers, and the proportion of workers reporting depressive symptoms is also high. These factors are associated to depressive symptoms. Furthermore, the gig workers associated between depressive symptoms and exposure to violence, job stress.

This study aims to examine two hypothetical models for the variables of students' environmental perspective. First hypothetical model is the mediating role of recognition and familiarity between aesthetic and negativistic perspectives. Second hypothetical model is the separate path from humanistic to dominionistic perspectives. One hundred four tenth grade students participated in this study. We used Pearson correlation, partial correlation, and path analysis to examine the fitness of hypothetical models. The findings showed that the mediating role of recognition and familiarity between aesthetic and negativistic perspectives were statistically accepted. To prevent students' bias for fancy or gross animals, the learning (for instance, recognition and familiarity) may play role in reducing the bias. Second, there were two differential paths from humanistic to dominionistic perspectives (ecologistic-naturalistic path and scientistic-utilitarian path). While ecologistic-naturalistic path does not reach dominionistic perspective, scientistic-utilitarian path does reach dominionistic perspective. To prevent students' dominionistic perspective for nature, they need to understand ecologistic-naturalistic minds for the nature.

Green dietary education emphasized environmental protection and humanity being conducted in middle schools. To develop effective green dietary education program for adolescents, the factors that affected their green dietary practices has been identified. This study aims to identify psychological factors that drive green dietary practices and effect of dietary education that targets middle school students. Data was collected twice from 242 middle school students in Daegu using a self-administered questionnaire in March and June, 2014. There were significant differences in school achievement, economic level and allowance a month (p<0.05) in the green dietary practices and efficacy of students. Three areas (environment, health and traditional, and appreciation & consideration) which were subgroups of green dietary practices were associated with factors such as family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive and negative feelings of happiness (p<0.001). Green dietary practices efficacy was significantly affected by family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive feeling, negative feeling, and negative relationships of happiness (p<0.001). After green dietary education, interests in green dietary, green dietary practices score, the score of health and environment factors of green dietary practices efficacy significantly higher than before education (p<0.05), but all the factors of self-esteem and happiness did not have any significant changes. This study suggests that green dietary education programs for middle school students could account for psychological factors such as self-esteem, happiness according to gender, school records, economic level and allowance a month to be effective.

In December 1990, Occupational Safety and Health Law was amended to reinforce employer's responsibilities on employees' health and safety. Among the amended law it was important to expand the role of an occupational health nurse to the role of an occupational health manager. An occupational health manager should take charge of coordinating periodic health examination and environmental hazard evaluation, providing primary care, monitoring employees' health status, giving the workplace walk-through, selecting safe protection equipment, providing health information, counseling and health education, independently. This position of occupational health nurse is equivalent to the role of doctors or occupational hygienists. In 1991, government made a master plan to prevent occupational disease and injury. Under the plan, Korea Industrial Nursing Association (KINA) was established in 1994 with the purpose of improving health services and upgrading career opportunities for members. Therefore, this study was designed to analyze the transition of occupational health nursing education with the changes of law and policy in Korea between 1991 and 1996. In details, it was to analyze the rate of school providing occupational health nursing practice based lecture, lecture hours, lecture contents in undergraduate curriculum, program contents of graduate school, kinds of continuing education, etc. For this purpose, we conducted survey two times. In February 1991, baseline study was conducted with all nursing programs in Korea (19 BSN programs and 43 nursing departments of junior college). From April to May in 1996, the second survey was conducted with all nursing programs (38 BSN programs and 69 junior colleges). The first response rate was 66.1% and the second was 40.6%. Structured questionnaires were mailed to the deans or the community health nursing faculties. In the case of graduate school, telephone survey was conducted with 10 school of public health or environmental health area. Data from the yearbook of Industrial Safety Training Institute (ISTI), the history of Korea Industrial Health Association, and the journals of KINA were also included in the analysis. As the results, we found that there were remarkable improvement in undergraduate and graduate programs, obligatory as well as voluntary continuing education in terms of occupational health nursing expertise between 1991 and 1996. 1) The number of school providing occupational health nursing practice-based lecture was increased with the rate from 7.3% to 25.6%. The rate of school giving over 15 class-hours was increased from 33.3% to 46.6%. 2) Content areas were composed of introduction of occupational health, occupational epidemiology, industrial hygiene, occupational disease and injury, law and policy, health education, concept of occupational health nursing, role of occupational health nurse, occupational health nursing process, etc. Of content areas, occupational health nursing process was more emphasized with the increased rate from 43.9% to 88.4%. 3) In the case of graduate school, occupational health programs were increased from 4 to 10. One of them has developed occupational health nursing program as an independent course since 1991. 4) The law increased educational hours from 28 hours to 36 hours for introductory course at the time of appointment, and from 14 hours to 24 hours every 2 years for continuing education. Course contents were Occupational safety and health law, introduction of occupational health, health education methodology, planning and evaluation, periodic health exam, occupational disease care, primary care, emergency care, management, industrial environment evaluation, etc. In 1996, Korea Industrial Nursing Association has begun to provide continuing education after Industrial Safety Training Institute. 5) Various educational programs in voluntary base were developed such as monthly seminar, CE articles, annual academic symposium, etc. It was shown that changes of law and policy led rapid growth of occupational health nursing education in various levels. From this trend, it is expected that occupational health nurse expertise be continuously to be enhanced in Korea. Legal and political supports should proceed for the development of occupational health nursing in early stage.
