This study was conducted among the university students to investigate the effects of working in an daytime and studying in an evening class on dietary behaviors and nutrient intakes. A 24-hour recall method was used along with food frequency questionnaires. The subjects were composed of three groups : 172 were in the daytime calss regular student group(RS), 178 were evening class students without a job(ESWOJ), and 140 were evening class students with a job(ESWJ). An average age of the ESWJ was 31 years old, which was 9 years older than the RS and 7 years older than the ESWOJ. The types of the residence were significantly different among the groups ; were seif-boarding 74% of the ESWJ stayed at home while 47% of the RS were self-boarding and 61% of the ESWOJ. The survey shows that while a great majority of the RS and ESWOJ has breakfast and supper at home, about 10% and 17% of the ESWJ ate breakfast and supper, respectively, at the cafeteria in their work place. The most frequently skipped meal was the breakfast in all groups. Approximately 9% of the ESWJ tended to skip the breakfast, while 27% of the RS and 33% of the ESWOJ did. It turns out that the mose common reason why ESWJ skipped meals was due to a lack of time. About 71% of the ESWJ ate out more than once a week compared to 57% and 62% of the RS and ESWOJ, respectively. Approximately 30% of the ESWJ ate out more than once a week compared to 57% and 62% of the RS and ESWOJ, respectively. Approximately 30% of the ESWJ spent less than 10 minutes at meal time, showing a hurried eating habit. The results show that the ESWJ tended to eat a variety of food s and eat less instant foods, but drink coffee more often compared to the other two groups. The results also show that in all groups, the intakes of energy, Ca, and vitamin A were lower than the Korean Recommended Daily Allowances(RDA). In addition to these nutrients, protein, vitamin B1, vitamin $B_2$, and niacin were also lower than the RDA in all make students, and Fe was lower than the RDA in all female students. Among the deficient nutrients, vitamin A showed the lowest % RDA : 48% in the male and 64% in the female students. Among the deficient nutrients, vitamin A showed the lowest % RDA ; 48% in the male and 64% in the female students. The intakes of Ca, Fe, and niacin in the ESWJ were significantly greater than those in the RS and ESWOJ groups, and the vitamin C intake in the ESWJ was greater than that in the ESWOJ(p<0.01). In conclusion, university students in all three groups have a serious imbalance in the nutrient intakes, and the evening class students with a daytime job have unhealthy dietary behaviors in the light of high frequency of eating out and heavy coffee drinking, a rushed eating pattern, and therefore showing a strong need of proper nutritional education for them.

Purpose: The purposes of this study were to investigate sleep quality and the related factors among clinical nurses. Methods: Data were collected from 208 nurses in general hospitals through self-report. Pittsburgh Sleep Quality Index (PSQI), Korean Epworth Sleepiness Scale (KESS), Insomnia Severity Index (ISS) were used. The data were analyzed t-test, ANOVA, $Scheff{\acute{e}}$ test, and multiple regression using the SPSS 20.0 program. Results: The mean scores of the subjects were $7.58{\pm}3.61$ on daytime sleepiness, $9.93{\pm}6.22$ on insomnia, and $7.29{\pm}3.05$ on sleep quality. The sleep quality in clinical nurses significantly influenced by insomnia (${\beta}=.55$, t=8.14, p<.001), daytime sleepiness (${\beta}=.16$, t=2.83, p=.005), and work satisfaction (${\beta}=-.15$, t=-2.35, p=.020). The three variables explained 55.9% of variance of sleep quality (F=10.73, p<.001). Conclusion: Sleep quality was influenced by daytime sleepiness, insomnia, and job satisfaction. To improve sleep quality, hospitals managers or leaders need to provide sleep promotion programs for preventing daytime sleepiness and insomnia.

This study aimed to identify workplace learning, job satisfaction and geriatric nursing practice, find the correlations between each variable, and investigate affecting factors on geriatric nursing practice. Subjects were 146 nurses in 9 long-term care hospitals including G City, and data were collected from May 1, 2016 through Jun. 30, 2016. Data analysis included independent t-test, one-way ANOVA, Pearson's correlation coefficient and multiple regression using the SPSS/WIN 20.0 program. The results showed that the correlations between each variable showed that incidental learning, a subregion of workplace learning (r=.20, p=.014), and job satisfaction (r=.29, p<.001) had a positive correlation with geriatric nursing practice, respectively. The affecting factors on geriatric nursing practice were job satisfaction, daytime working and nursing experience, and the explanatory power of the model was 20%(F=4.91, p<.001). Based on the results, job satisfaction should be increased to improve the quality of nursing in long-term care hospitals and various methods might be discussed to improve the job satisfaction. Daytime working was suggested one factor on geriatric nursing practice because nursing was provided mainly during daytime, and nursing experience was also one factor on geriatric nursing practice, so highly experienced geriatric nurses could provide high quality elderly patient care.

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.

Purpose: This study aimed to investigate problem behavior and its related factors in school-aged children. Methods: A descriptive correlational study was conducted with 221 mothers of children at 1st to 6th grades. Data were collected from March to April, 2015 using self-report structured questionnaires. Questionnaires included characteristics of subjects, Korean Child Behavior Checklist for measuring problem behavior and Children's Sleep Habits Questionnaire for assessing sleeping habits. Collected data were analyzed by independent t-test, $x^2$ test, and multiple logistic regression. Results: In logistic regression analysis, having any maternal job (aOR=2.8, 95% CI=1.1~6.9) and higher daytime sleepiness (aOR=2.9, 95% CI=1.2~7.4) were statistically significant contributors of internal problems. Higher bedtime resistance (aOR=2.2, 95% CI=1.0~4.9) and higher daytime sleepiness (aOR=2.8, 95% CI=1.2~6.3) were statistically significant contributors of external problems. Higher bedtime resistance (aOR=4.3, 95% CI=1.5~12.4) was statistically significant contributors of total problem behavior. Conclusion: School-aged children with sleeping problem are at risk for problem behavior. More attention is need to consider sleeping habits for supporting behavioral improvement in school-aged children.

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.
