This study was conducted to examine effects of community gardening on job stress and job satisfaction experienced by public officials in general administration working in a 24-hour shift. The subjects were public officials at the Center for Missing Children in the Department of Women and Adolescents at the National Police Agency. The center receives initial reports of disappearance of missing children, the elderly with dementia, and people with intellectual disabilities, sends out the report to each police station, and clears the report after the missing individual is found. Twelve public officials working at the center in a double shift (full day off after a night shift, four-day interval) were grouped into four teams and total 11 of them participated in the experiment. They engaged in autonomous community gardening activities such as sowing seeds, cultivating plants, harvesting, or cooking in the workplace for five weeks from August 19 to September 22, 2018. The findings were as follows. After five weeks of autonomous gardening activities, job stress of the subjects decreased significantly. Their mean scores of job satisfaction and organizational commitment under organizational effectiveness showed a significant increase after the activities. Finally, there were significant differences in their self-esteem after participating in the gardening activities in the workplace. These results suggest that gardening activities in the workplace can help to manage job stress and quality of work life for shift workers.

Purpose: Work-related stress and risk factors among Korean employees were identified in this study. Methods: Data were obtained from employees aged 20 to 64 using the Korean Working Conditions Survey 2006 (KWCS). Multiple logistic regression analysis using SAS version 9.1 was performed to examine risk factors of work-related stress by gender. Results: The age-adjusted prevalence of work-related stress among male and female employees was 18.4% and 15.1% respectively. After adjustments for multiple variables among both male and female employees, there was a significant relationship between work-related stress and risk factors including education, company size, work time, ergonomic risks, biological chemical risks, and job demands. The significant variables for male employees were housework load, occupational class, and shift work, and for female employees, type of employment. Conclusion: There is a need to develop and support intensive stress management programs nationally giving consideration to work-related stress associated with working time, physical working environment, and job demands. Based on gender specific approaches, for male employes, stress management programs should be developed with consideration being given to occupational class and shift work. For stress management programs for female employees, consideration needs to be given to permanent employment status, specifically those in small companies.

Purpose: This study is to investigate the job stress and presenteeism of nurses with work shift. Methods: The data were collected through questionnaires from 281 clinical nurses working for a university hospital located in D city from 13 to 28 of February, 2009. The data were analyzed by descriptive statistics, t-test, ANOVA, Scheffe verification test, Pearson correlation coefficient and multiple linear regression using SPSS/WIN 16.0. Results: The mean score of job stress was 3.47. Work overload and psychological burden scored the highest point as the sub-category of work stress factor. Work performance loss out of presenteeism showed 26.89 and perceived productivity, 79.79. Also 94.7% of respondents answered they had health problems. A significantly positive correlation was found among job stress, work performance loss and health issue. To determine the factors affecting presenteeism, work performance loss was associated with work overload and perceived productivity with interpersonal relationship conflict. Conclusion: Based on the findings of the study, job stress is positively correlated with work performance loss, and health problems. Therefore, health problems of nurses with work shift need to be considered and plans to manage their job stress affecting presenteeism need to be developed at an earlier stage.

Firemen are directly exposed to various harmful chemicals, physical factors and mental stress during rescue and fire-fighting. In fire extinguishing, unstable posture, poisonous gas, dust, high temperature and heavy equipments are possible hazardous factors. The alertness for emergency, shift work, job strain and stress are also possibly hazardous. Therefore, this study aimed to investigate the prevalence of musculo-skeletal symptoms and job stress and to determine risk factors in firemen. This study was carried out in a group of 226 firemen in Busan City, Korea. Standardized Nordic Questionnaire was used to investigate the prevalence of musculo-skeletal symptoms and Psycho-social Well-being Index (abbreviated PWI) was used to investigate the prevalence of job stress. General and occupational characteristics were included education, marital status, alcohol and smoking history, working duration, and work shift system. Body mass index (BMI) scores were calculated by physical examination including height and weight. Concerning musculo-skeletal complaints, the commonest site was neck, and shoulder, lower back, upper back were the next. Complaint site above one area of body was about 80%. From multiple logistic regression analysis, working duration was significant variable in musculo-skeletal symptoms. Odds ratio were 15.4 in working duration. About 16.8% was high risk stress group. From multiple logistic regression analysis, shift work and alcohol drinking were significant variables in PWI scores. Odds ratios were 2.25 in shift work. Accordingly, interventions are needed for health promotion of long term and shift worker.

Objectives: This study was conducted to assess the association between level of physical activity and depressive symptoms among Korean male workers. Methods: A self-administered questionnaire was distributed and anthropometric measurements were conducted with 1,379 male workers during a general health check. From this data, we identified the general characteristics, levels of physical activity(IPAQ), and depressive symptoms(CES-D) of the study population. We conducted univariate logistic regression to verify the variables that affect depressive symptoms and multivariate logistic regression to calculate odds ratios. Results: Among the 1,379 male workers, 43.4% were in the insufficiently active group(IPAQ category 1) and 22.8% were in the depressive symptom group($CES-D{\geq}16$). The odds ratio(OR) for depressive symptoms was statistically higher in the insufficiently active group, workers aged over 30, the shift work group, and the unmarried group. Adjusted for those variables, the ORs for depressive symptoms were found to be 1.45(95% CI=1.25-2.11), 1.15(OR=1.15, 95% CI=1.08-1.99) and 1.75(95% CI=1.48-2.02), for the insufficiently active group, workers aged over 30, and the shift work group, respectively. Conclusions: We found physical inactivity, age, marital status, and shift work to be associated with depressive symptoms among male workers. This study supports the suggestion that physical activity can be helpful to reduce depressive symptoms among workers.

We investigate what happens when we try to work with continuing block codes (i.e., left or right continuing factor maps) between shift spaces that may not be shifts of finite type. For example, we demonstrate that continuing block codes on strictly sofic shifts do not behave as well as those on shifts of finite type; a continuing block code on a sofic shift need not have a uniformly bounded retract, unlike one on a shift of finite type. A right eresolving code on a sofic shift can display any behavior arbitrary block codes can have. We also show that a right continuing factor of a shift of finite type is always a shift of finite type.

The CO molecules adsorbed on Ni(111) surface is studied in the cluster approximation employing EH method with self-consistent charge iteration. The effect of CO coverage is simulated by allowing the variation of valence state ionization potentials of each Ni atom in model cluster according to the self-consistent charge iteration method. The CO coverage dependent C-O stretching frequency shift, adsorption site conversion, and metal work function change are attributed to the charge transfer between metal surface and adsorbate. For CO/Ni(111) system, net charge transfer from Ni surface to chemisorbed CO molecules makes surface Ni atoms be more positive with increasing coverage, and lowers Ni surface valence band. This leads to a weaker interaction between metal surface valence band and Co $2{\pi}^{\ast}$ MO, less charge transfer to a single CO molecule, and the bule shift of C-O stretching frequency. Further increase of coverage induces the conversion of 3-fold site CO to lower coordination site CO as well as the blue shift of C-O stretching frequency. This whole process is accompanied by the continuous increase of metal work function.

Objective Determine differences between faculty, residents, and nurses regarding night shift preparation, performance, recovery, and perception of emotional and physical health effects. Methods Survey study performed at an urban university medical center emergency department with an accredited residency program in emergency medicine. Results Forty-seven faculty, 37 residents, and 90 nurses completed the survey. There was no difference in use of physical sleep aids between groups, except nurses utilized blackout curtains more (69%) than residents (60%) and faculty (45%). Bedroom temperature preference was similar. The routine use of pharmacologic sleep aids differed: nurses and residents (both 38%) compared to faculty (13%). Residents routinely used melatonin more (79%) than did faculty (33%) and nurses (38%). Faculty preferred not to eat (45%), whereas residents (24%) preferred a full meal. The majority (>72%) in all groups drank coffee before their night shift and reported feeling tired despite their routine, with 4:00 a.m. as median nadir. Faculty reported a higher rate (41%) of falling asleep while driving compared to residents (14%) and nurses (32%), but the accident rate (3% to 6%) did not differ significantly. All had similar opinions regarding night shift-associated health effects. However, faculty reported lower level of satisfaction working night shifts, whereas nurses agreed less than the other groups regarding increased risk of drug and alcohol dependence. Conclusion Faculty, residents, and nurses shared many characteristics. Faculty tended to not use pharmacologic sleep aids, not eat before their shift, fall asleep at a higher rate while driving home, and enjoy night shift work less.
