Purpose: This study examines the effect of aroma inhalation therapy with lavender and rosewood essential oils for alleviating fatigue and enhancing quality of sleep in nurse shift workers. Methods: The data were collected from November 9th to 27th in 2009 at four hospitals located in Seoul. Total 60 nurses who started their night-shift works were chosen for the study and allocated to either experimental group or control group. The experimental group had had aroma inhalation therapy with lavender and rosewood for 2 weeks and was compared the level of fatigue and quality of sleep with those of the control group. Results: Significant differences were shown between the experimental group and the control group. After 2 weeks, the nurses in experimental group reported significantly lower level of fatigue and higher quality of sleep compared to the nurses in control group. Conclusion: Therefore, aroma inhalation therapy by using lavender and rosewood essential oils can be an effective intervention for relieving the level of fatigue and enhancing quality of sleepf for nurse shift workers.

Purpose: The purpose of the study was to investigate the relationships between worker's health belief in health promotion programs and their demographic, health, and health behavior characteristics. Methods: This study used survey data from 262 small- and large-scale workplaces. The study included 1149 male and female workers who completed the questionnaires. Results: The health belief score increased significantly with age and length of service. Male, married, shift-work, and white-collar workers showed a significantly higher health belief score than female, single, non-shift-work, and blue-collar ones. Workers with disease history, hypertension, or obesity had a significantly higher health belief score. Regular exercise was significantly correlated with the health belief score. When all the variables were included in the model, the health belief score was significantly higher in workers who were married, had a longer length of service, worked in the sales department, were diagnosed with hypertension, exercised regularly, and felt fatigue. Conclusion: The results showed that workplace intervention programs meet more the needs of workers who have a higher health belief score. In addition, given that healthier life style was related to a higher health belief score, further research is required to find how to change health behavior in workers.

Job stress factors are factors that induce biological, psychological, and behavioral responses in individuals when they encounter mental and physical stimuli in the workplace. According to occupational safety and health standards, employers are responsible for the health consequences of job stress when workers engage in activities that result in high levels of physical fatigue and mental stress. Such activities include long working hours, shift work (including night shifts), driving vehicles, and operating precision machinery. Therefore, precautionary measures should be implemented. Following the COVID-19 epidemic, the logistics industry in Korea has experienced rapid growth owing to the shift from offline to online platforms facilitated by advanced digital infrastructure. Consequently, this study conducted a survey to analyze job stress factors among delivery workers. The survey utilized a Korean job stress factor assessment tool comprising 43 items and analyzed job stress factors considering the work characteristics of the courier business field obtained from responses provided by 421 courier workers nationwide. The survey analysis revealed that the physical environment, job demands, and job autonomy exhibited higher stress indices among Korean workers. Furthermore, the younger the age, the higher the stress on job demands, whereas the higher the age, the higher the stress on relationship conflict, job instability, and workplace culture. In addition, daytime delivery work was associated with higher stress levels in job demands and job instability compared with nighttime delivery work. These findings can serve as foundational data for reducing and preventing job stress among courier workers, whose workload has increased owing to the growth of the logistics industry.

The purpose of this study was carried out to rind out the prevalence of occupational musculoskeletal disorders among workers in manufacturing industries, so that the result could provide basic data necessary to prevent musculoskeletal disorders. Information on general characteristics, occupational characteristics, and musculoskeletal symptoms were obtained by a self-administered questionnaire between October and November in 2002, from 345 workers in Kim-hae and Ulsan, Kyung-nam province. The data were analyzed for chi-square test by using SPSS NVIN 10.0 program. The results are as follows: According to the self-reports, among musculoskeletal symptoms complain on shoulders are topping for 50.4%, low back is followed for 40.6%, leg/foot 35.7%, neck 34.5%, wrist/hand/finger 30.1%, and arm 24.3%. According to occupational characteristics prevalence by anatomical site, about neck pains 119 subject, occupational satisfaction is 62,6% in moderate group, work shift is 71.8% in no work shift group, each significant high. Symptom complain rate of 104 patients who complained on wrist, hand and finger pain is significantly related that 36.5% below 5 years and 36.5% above 15 years have been worked group. And each of them are significantly related 77.9% in labor workers group, 70% in no work shift group, 54.8% in frequent transfer group. Among 140 subjects who have back pain, that is significationtly reported on 37.1% below 5 years and 37.9% above 15 years and 60.0% moderate satisfied occupation group have been worked group. Therefore, some efforts should be proceeded such as improvement of working condition, flexibility for changing work, more pleasant and better working environment, and etc.

This study aimed to compare general and female health-related factor between day-work and shift-work worker. It is based on the data of the Korea National Health&Nutrition Examination Survey(KNHANES) 2nd year on 7th period. The number of participants was 10,430. Out of the participants, 1,995 workers' dara was analyzed. The age, marital status, education level, occupational status and childbirth experience of female workers indicated significant differences between day and shift work. By contrast, health-related quality of life did not represent significant differences these factors; income, subjective health cognition, stress perception, depression experience, menarcheal age, menopausal age and breastfeeding period. The shift work is inevitably implemented as an industrial development and flexible work hours. Therefore, social and national attention and measures as well as those of individual workers are required to reduce the side effects from shiftwork.

In spite of many previous studies conducted to prevent safety accidents at construction sites, the frequency of safety accidents has not decreased. And recently, a lot of research has been done to analyze the causes of the accidents resulting from the personal characteristics and behaviors of managers or workers, and eliminate them. However, despite these efforts, safety accidents occur consistently as managers and workers shift their responsibilities for the safety accidents onto someone other than themselves. Therefore, in order to prevent safety accidents, this study investigated the consciousness of shifting responsibility among managers and workers and analyzed the correlation between factors influencing the consciousness of shifting responsibility. In addition, it proposed the quantitative levels of the consciousness of shifting responsibility based on the survey of managers and workers. The results of this study demonstrated that managers tend to the shift responsibility onto workers, whereas workers the shift responsibility onto managers. It was additionally demonstrated that there is a correlation between the consciousness of shifting responsibility and the factors influencing it. The findings of this study are expected to improve the safety awareness among managers and workers and make contributions in the theoretical and practical aspects of construction safety management.

The factors influencing nicotine dependence of smoking shift workers (154 samples), working in manufacturing industry, were investigated. 23.4% of the sample showed moderate nicotine dependence while 14.3% did severe dependence. Nicotine dependence showed statistically significant difference with respect to sex, disease, and health condition and was positively correlated with occupational stress. Occupational stress, sex, and disease were identified as the influential factors, explaining 43.9%, and should be the basis for intervention to reduce nicotine dependence.
