Purpose: The purpose of this study was to investigate the sleep duration, social jetlag (SJL), and subjective sleep disturbance according to the individual chronotype in rotating shift nurses. Methods: A total of 344 rotating 3-shift nurses (mean age 28.67 years) were recruited at one university affiliated hospital. They completed the following questionnaires, which were used to assess their chronotype and sleep: the morningness-eveningness questionnaire (MEQ), self-reported sleep duration of work days (SDW_shift) and free days (SDF_shift) in each shift (day [D], evening [E], night [N]), and sleep disturbance (Insomnia severity index, ISI). SJL_shift was calculated as the difference in midsleep (MS=sleep onset+1/2 sleep duration) between work days (MSW) and free days (MSF). Results: Subjects were divided into 3 chronotype groups according to the MEQ; morning (MG, 4.4%) intermediate (IG, 57.8%), and evening groups (EG, 37.8%). SDW_D was shortest (4.68 hr) and SDF_E was longest (8.93 hr) in the EG. SJL_D was longest in the EG (3.77 hr), and SJL_N was longest in the MG (7.37 hr). The prevalence of sleep disturbance was 33.3% (MG), 29.6% (IG), and 40.0% (EG), respectively, without any statistical significance. Conclusion: In order to improve the sleep of shift workers, it is recommended that the evening chronotypes should reduce the day shifts and the morning chronotypes should reduce the night shifts. We also propose a study to determine whether these shift assignments can improve the sleep in shift nurses.

Background: This study aimed to identify the validity of breast cancer symptom questionnaire of worker's special health examination and its relationship with breast ultrasonography findings in young female night workers. Methods: The breast cancer symptom questionnaire data of worker's special health examination and breast ultrasonography results in young female shift workers who worked in one electronic manufacture company were collected from 2014 to 2018. Results: Of the 857 workers, 18 had a Breast Imaging Reporting and Database System category 4 or higher. Among other variables, shift work tenure alone was associated with the risk of having a Breast Imaging Reporting and Database System category higher than 4. The sensitivity, specificity, positive predictive value, and negative predictive value of the symptom questionnaire were 16.7%, 87.7%, 2.8%, and 98.0%, respectively. Conclusion: The current breast cancer symptom questionnaire of the worker's special health examination is inappropriate due to its low sensitivity and positive predictive value. In the future, female night workers will need alternative measures for more accurate screening for breast cancer.

Objective: An automated process for medication preparation and dispensing is essential to improve the quality of work. To reduce night pharmacy workload, a new automated dispensing cabinet system was implemented in a hospital emergency medical center. The purpose of this study is to verify that implementation of an automated dispensing cabinet system will influence the efficiency of night pharmacy work. Methods: To evaluate the new system implementation, a retrospective study and survey was performed in the Ewha Womans University medical center. We compared the dispensing and near-miss error rates between the automated dispensing cabinet system and a night pharmacy. The degree of satisfaction of night shift workers with the new system was surveyed. Results: This study showed significantly reduced dispensing rates of night medications (56.1% and 37.3%; p < 0.01) and near-miss night medications (0.27% and 0.17%; p<0.01). Thirty-two persons responded to the survey, and the satisfaction score for the new system was 4.0 (${\pm}0.8$). The scores were high in order of efficiency, management, and convenience. Time requirement was also reduced because of the simple step of only reviewing in the pharmacy with the new system. Conclusion: Due to system implementation, workload was reduced and time was saved for not only night shift workers but also patients receiving emergency discharge medicine. It was suggested that this will have a positive effect on pharmacist medical service and patient safety.

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.

본 연구는 일반병동에 근무하는 교대근무 간호사의 간호업무 수행실태와 직무만족도를 확인하기 위한 2차 자료 분석 연구이다. 연구 결과, 전체 간호 업무 중 대상자가 수행한 직접간호는 45%, 간접간호는 55%를 차지하였다. 교대 근무별로 주간에 수행한 업무량은 전체 업무량의 37.2%였고 인계 후 수행한 업무는 '직접간호(34.5%)'와 '기록과 보고(25.8%)'였다. 대상자들은 본인이 수행한 업무 중 일부분에 대해 간호보조 인력에게 위임 가능하거나, 타 의료인과 경계가 모호한 업무가 있다고 응답하였다. 야간근무의 직무이행도와 직무만족도 간의 유의한 상관관계(rs=.43, p=.01)가있었다. 이러한 결과는 교대근무별 직무분석에 근거한 업무효율성 제고 및 EMR적용, 스마트 기기 등을 활용한 인계시간 감소 전략, 업무 수행주체를 명확히 하는 방안이 필요함을 시사한다.

Purpose: The purpose of this study was to investigate the differences in sleep, fatigue, and neurocognitive function between shift nurses and non-shift nurses. Methods: A cross-sectional descriptive study design was used. A total of 100 nurses participated in the study. 50 were shift nurses and the remaining 50 were non-shift nurses. The Pittsburgh Sleep Quality Index, Fatigue Severity Scale, and a computerized neurocognitive function test (CNS Vital Signs-VS4) were administered to the subjects to assess verbal and visual memory, processing speed, reaction time, and simple attention. After the last night shift, the shift nurse conducted the study at around 8:00 am and the non-shift nurse participated after work. Results: Compared to non-shift nurses, shift nurses had a significantly lower sleep quality (p=.002) and higher fatigue (p=.001) and achieved significantly lower scores on verbal memory (p=.001), processing speed (p=.003), and reaction time (p=.018). There were significant correlations between sleep quality and processing speed (p=.042), and reaction time (p=.015) of shift nurses who were bad sleepers. Conclusion: This study findings suggest shift work could interfere with cognitive function. Personal and organizational programs should be developed to support their sleep and neurocognitive function.

We evaluated the eating pattern, physical activity, and daytime sleepiness level in Chilean shift workers. Fifty, middle-aged adult health workers from a public hospital in Santiago, Chile, were included: a group undergoing shift work (shift workers, including at least one "night shift" and one "long day", n = 33), and day workers under traditional schedule (from 8:00 to 17:00h, n = 17). Body composition, physical activity, and daytime sleepiness levels, and diet characteristics (diet composition, meals' timing, and diet quality) were assessed. Despite similar total energy intake, shift worker showed lower carbohydrate (% of energy) and higher protein intake (both P < 0.01), decreased diet quality, an irregular eating pattern, and delayed meal timing (all P < 0.05). Physical activity and daytime sleepiness levels did not differ between groups. Findings from this first Chilean study in healthcare shift workers support the fact that meal timing and diet quality appear as critical factors for upcoming intervention studies in this group.

Objectives: This study evaluated the association between work related characteristics and hypertension among white collar workers in Korea. Materials and methods: This study was based on the Third Korean Working Conditions Survey(KWCS) conducted in 2011 among workers 15 years of age or older. The total number of individuals included in the analysis was 10,365 white collar workers. Results: The prevalence rate of hypertension was 3.7% among men and 1.0% among women. In multiple logistic analysis the adjusted odds ratio showed statistically effective association to hypertension. For work related characteristics, 1.73 (95% confidence interval, 1.22-2.46) resulted for large-company workers compared with the small-company group, 2.14 (95% CI, 1.22-3.75) for the long working hours group (61 or above) compared with short working hours group(52 or below), 1.78(95% CI, 1.08-2.95) for night shift workers compared with day workers, and 1.54 (95% CI, 1.18-2.01) for high job stress workers compared with low job stress workers. Conclusions: This study showed that it is important for workers to manage their work environment in order to prevent hypertension by modifying their types of work.
