As social distancing is implemented to prevent the spread of COVID-19, there is an increasing number of workers participating in telework. This study aims to classify the feasibility of working at home for occupations and industries based on physical working conditions, and to analyze regional distribution of the teleworkable jobs. And the raw data of the Korea Working Conditions Survey is used to examine working environment and characteristics of jobs. The main findings show that 35% of jobs in South Korea can be done at home, and the occupations that are less amenable to work at home are closely related to the economically vulnerable workers who earn low wages. Furthermore, the regions that are heavily dependent on manufacturing for employment are likely to have a lower share of jobs that can be done at home due to the industrial structure and working conditions.

In this study, I examine whether differences in the levels of job satisfaction and turnover intention exist with regard to the police department size. To accomplish this, a way ANOVA analysis of variance(One-way ANOVA) was conducted. As a result, a significant differences were found in job satisfaction and turnover intention according to the department size and grade. Specifically, first, in the job satisfaction level on the department size, the smaller department size was, the lower job satisfaction level was and the bigger department size was, the higher job satisfaction level was. Second, in the turnover intention level on the department size, the result was not statistically significant. Third, in the job satisfaction level on the department grade, the lower department grade was, the higher job satisfaction level was and the higher department grade was, the lower job satisfaction level was. Fourth, in the turnover intention level on the department grade, the lower department grade was, the lower turnover intention level was and the higher department grade was, the higher turnover intention level was.

Purpose: The purpose of the study was to identify teacher's knowledge about sodium, dietary behaviors related to sodium, attitudes towards a low-salt diet, and meal attitude guidance as well as examine the relationship between these variables. Methods: The participants were 351 teachers at an elementary school in the Jeonbuk area. The data were analyzed using ANOVA, Duncan test, and Pearson correlation coefficients with SPSS v. 20.0. Results: The score for teachers' knowledge about sodium was 12.92 points of a possible 16, the score for dietary behavior related to sodium was 46.85 points of a possible 70, and the score for attitude towards a low-salt diet was 33.63 points of a possible 50. Their score for meal attitude guidance was 59.95 points of a possible 80. The knowledge showed significant differences by hypertension drug (p < 0.05) and stress level (p < 0.05). The dietary behavior of sodium use showed significant differences by gender (p < 0.01), work experience (p < 0.05), BMI (p < 0.01), drinking (p < 0.05), concern about health (p < 0.05), and stress level (p < 0.05). The attitude towards a low-salt diet showed significant differences by gender (p < 0.05), marital status (p < 0.05), work experience (p < 0.05), drinking (p < 0.05), concern about health (p < 0.001), and stress level (p < 0.05). Meal attitude guidance showed a significant difference by marital status (p < 0.001), age (p < 0.001), work experience (p < 0.001), drinking (p < 0.01), regularity of health checkup (p < 0.001), concern about health (p < 0.001), and stress level (p < 0.05). There was a low positive correlation between knowledge about sodium and dietary behavior related to sodium as well as between dietary behavior related to sodium and attitudes towards a low-salt diet. Attitudes towards a low-salt diet showed a positive correlation with meal attitude guidance. Conclusion: Therefore, it is necessary to consider educational programs on increasing knowledge and attitudes towards a low-salt diet in teachers for improvement of meal attitude guidance activities for students.

This study analyzed the effects of job stress and sleep disorders on sleepiness during the daytime for a night-shift urban railway crew. As a result of the analysis, measurements on a daytime sleepiness index were higher for the crew than those during other working hours, indicating that the degrees of sleepiness and drowsiness were severe. Afterwards, aromatic essential oils, which are generally known to help relieve sleep disorders and stress, were utilized to verify the effect on stress on night-shift workers. The experimental group treated with aromatherapy was found to show improved stress reduction and overall activity levels in the autonomic nervous system compared to an untreated control group. This study proves that night work by an urban railway crew negatively affects stress levels by increasing stress and negatively affects the autonomous nervous system, also showing that an aromatherapy treatment can be a good alternative to alleviate these conditions. The results of this study are expected to help prevent safety accidents by relieving the stress of nighttime workers.

Objectives: Working at other times than the regular day shift has been reported to be a stressor associated with health consequences and mental disorders as well as disturbance of sleep. In current study, we aimed at investigating the relationship between work schedule, sleep quality and depression among police officers. Methods: Eleven hundreds and forty five police officers (male: 1040, female: 105) completed questionnaires of basic socio-demographic data, Pittsburgh Sleep Quality Index (PSQI), Korean Scale of Occupational Stress (KOSS), Impact of Event Scale - Revised (IES-R) and Center for Epidemiologic Study-Depression (CES-D). Results: After controlling for age, sex and educational level, score of CES-D was correlated positively with the score of KOSS, PSQI and IES-R on partial correlation analysis (r=-0.077; p=0.009, r=0.262; p<0.000 and r=0.421, p<0.000, respectively). Logistic regression analysis revealed that female sex, age, the score of KOSS and IES-R and schedule of rotating shift work predicted higher score than 16 score of CES-D significantly in total subjects (p=0.023, p=0.015, p=0.000, p=0.000 and p=0.022, respectively). Conclusion: Current result suggested that not only female sex, age, higher occupational stress and impact of event scale but also rotating shift work schedule might be related to depression among police officers.

교육인적자원부에서는 학교급식의 안전성 확보를 위하여 1999년에 특별정책 연구를 실시하여 학교급식 HACCP 일반모델을 개발 보급하고 2001년부터는 규모가 큰 학교에서 조리실이 설치된 모든 급식학교로 점진적으로 적용을 확대하였다. 그럼에도 불구하고 학교급식에서 식중독 사고는 증가 추세에 있으므로 학교급식에서의 HACCP 시스템을 재진단하고 수행도가 낮은 중점관리점의 문제점을 짚어내는 것이 필요하다. 따라서 본 연구에서는 대전지역의 초, 중, 고등학교 영양사 153명을 대상으로 위생관리 직무 수행도와 HACCP의 일부 CCP (중점관리점)수행도, HACCP에 대한 인지도, 급식시설현황 등에 대하여 조사하고 변인간의 관련성을 분석하였다. 조사 대상자는 초등학교 영양사 56.5%, 중학교 영양사 25.5%, 고등학교 영양사 17.6%이었으며 4년제 대학 졸업자가 51.0%로 가장 많았고 연령은 30-34세가 36.6%, 35-40세가 21.6%로 30대가 대부분이었다. 근무경력은 평균 5.8년이었으며 영양사 1인당 담당하는 평균 학생수는 1,163명, 조리종사원 1인당 배식 아동수는 평균 124명이었다. 배식방법은 교실배식이 56.2%, 식당배식 34.6%, 교실과 식당의 혼합형태가 9.2%로 교실배식이 차지하는 비율이 많았고 직영급식이 90.2%로 대부분을 차지하였다. 위생관리 영역의 수행도는 개인위생관리 부문이 가장 높았고 기기설비 위생관리, 저장관리, 교차오염관리, 시간관리, 온도관리 순으로 나타났으며, 특히 온도관리 수행도는 낮은 것으로 나타났다. 식당배식을 실시하는 학교의 온도관리 수행도가 다른 그룹에 비해 높았고 직영급식의 시간관리수행도가 위탁급식 보다 높았다. 영양사의 연령과 근무경력이 증가할수록 모든 위생관리영역에서 수행도가 높아지는 경향을 보였다. CCP별 수행정도 평가에서는 ‘운반 및 배식과정(CCP7)’이 가장 높은 수행도를 나타냈고 그 다음으로는 ‘검수’, ‘식품취급 및 조리과정’, ‘식품접촉 표면 세척 및 소독과정’, ‘식단의 구성’, ‘생채소 및 과일의 소독’, ‘잠재적으로 위험한 식단의 관리’ 순으로 나타났다. ‘운반 및 배식과정의 수행도’는 식당배식이 유의적으로 높은 점수를 보였고 CCP8(식품접촉표면의 세척 및 소독)를 제외한 모든 영역에서 직영급식이 위탁급식에 비해 높은 유의성을 나타내었다. 또한 근무경력과 연령이 많을수록 모든 CCP영역에서 높은 수행도를 보였다. CCP1과 CCP2의 수행도가 낮은 주된 이유로 ‘CCP1과 CCP2의 관리기준이 이해하기 어렵다’이었다. 학교 급식관리 영양사의 HACCP시스템에 대한 지식 및 이해 정도를 조사한 결과 HACCP 인지도 점수의 평균은 총 100점 만점에 전체 평균 점수는 74.9점이었다 CCP별 점수분포는 CCP7의 인지도 점수가 가장 높았고 CCP6, CCP1, CCP5, CCP3, CCP8, CCP2의 순으로 절차 낮아졌다. 정규직의 HACCP인지도 점수가 위탁직 보다 높았으며 근무경력에서도 경력이 3년 미만인 경우가 가장 낮고 8년 이상인 경우가 가장 높은 점수를 보였다. 급식시설면은 보온보냉시설을 갖춘 학교가 온도관리 부문에서 갖추지 않은 학교보다 높은 수행도를 나타냈고, 전처리실과 손 소독기가 있는 학교는 교차오염관리 부문에서 높은 수행도를 보였다.

This study provides basic data needed to improve the working environment of the first class emergency medical technicians, in order to decrease their job stress and increase their job satisfaction. Job stress and satisfaction were compared and analysed in emergency medical technicians who were working for 119 rescue and hospitals at the time when twenty-one years had passed after the initial training of emergency medical technicians in order to identify differences between 119 rescue and hospitals, and their advantages and disadvantages. The subjects of the study were 182 first-class emergency medical technicians who were working in twenty-eight 119 rescue centers and fourteen national and local emergency medical centers in Gwangju, Jeollanamdo and Jeollabukdo. The study subjects were interviewed by questionnaire. For statistical analysis, SPSS/WIN 20.0 was used, and the results were analysed with chi-square, t-test, ANOVA, and ANCOVA testing. There was no significant difference in job stress between the subjects working in 119 rescue centers (2.92) and those working in hospitals(3.01). The satisfaction score of fire-fighting workers was 2.98 and that of hospital workers was 2.54. Hospital workers' satisfaction was significantly lower (p<0.001). The score of hospital workers' pay satisfaction was the lowest($2.07{\pm}0.62$). The job stress decreased and job satisfaction increased with decreasing monthly average number of patients(p<0.001), increasing monthly income(p=0.047), and more frequent holidays they had(p<0.001), the less. For less job stress and higher job satisfaction, welfare conditions both at 119 rescue and hospitals should be improved. 119 rescue centers should develop violence prevention measures and offer resting places for emergency medical technicians. Hospitals should pay more attention to the yearly pay increase rate and stability in employment types.
