Purpose: This study examined health behaviors, use of health services, and depression among women who perform daytime and shift work in Korea, as well as factors related to depression. Methods: We conducted a secondary analysis using data from the 2018 data of the 7th Korea National Health and Nutrition Examination Survey. Data on women, 1,493 regular daytime workers and 322 shift workers, were analyzed. Results: Women shift workers (χ²=43.97, p<.001), had a lower education level (χ²=45.56, p<.001), and lower personal income (χ²=16.85, p=.030) than their daytime counterparts. A higher proportion of shift workers were unmarried (χ²=37.47, p<.001) and they typically worked fewer than 40 hours per week (χ²=69.94, p<.001). The depression score of shift workers was higher than that of daytime workers (t=2.85, p=.005). A higher proportion of shift workers also drank alcohol (χ²=6.49, p=.032) and smoked (χ²=30.79, p<.001). Over 8% of shift workers typically slept fewer than 5 hours per night (χ²=14.17, p=.024). It was confirmed that depression in women shift workers was affected by age, personal income, marital status, health status, and smoking status, in addition to cancer screening participation, unmet medical care needs, and unmet dental care needs. Conclusion: More attention should be given to the health needs of women working shifts. Health promotion programs specific for women shift workers are needed to improve their physical and mental health, encourage use of medical care services, and improve public health policies and systems.

In order for start-up establishment to enter the business market, it has to get over the first mover advantage of the existing establishment. As a result, its working condition deteriorates and a great deal of occupational accidents take place. Based on 2009 standard, the occupational accident rate of start-up establishment is 1.28%, which is two times higher than existing establishment and the gap between manufacturing and service industry has been getting wide. For the characteristic of injured person in start-up establishment, it is showed that the occupancy rate of women and people with less than 30 age starting out in a career is high and the occupancy rate of occupational accident for holiday and night work is high. Therefore, the act for occupational accident prevention is needed in the early period of business and underprivileged group for occupational accident.

The objective of this work is the air quality modeling according to the practical roughness length using the building information as surface boundary conditions. As accurate wind and temperature field are required to produce realistic urban air quality modeling, comparative simulations by various roughness length are discussed. The prognostic meteorological fields and air quality field over complex areas of Seoul, Korea are generated by the PSU/NCAR mesoscale model (MM5) and the Third Generation Community Multi-scale Air Quality Modeling System (Models-3/CMAQ), respectively. The simulated $O_3$ concentration on complex terrain and their interactions with the weak synoptic flow had relatively strong effects by the roughness length. A comparison of the three meteorological fields of respective roughness length reveals substantial localized differences in surface temperature and wind folds. Under these conditions, the ascended mixing height and weakened wind speed at night which induced the stable boundary stronger, and the difference of simulated $O_3$ concentration is $2{\sim}6\;ppb$.

Purpose: The purpose of this study was to investigate factors which effect clinical nurses' exhaustion. Methods: This research was conducted targeting 140 clinical nurses. Data were collected from 18 September to 30 September 2015. Data were analyzed using the program SPSS/WIN 18.0. Descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression analysis were used. Results: Burnout was significantly different by age (F=7.99, p=.001), marital status (t=8.69, p=.004), department area (F=7.65, p<.001), frequency of night work in a month (F=7.65, p=<.001), and clinical career (F=3.68, p=.028). There was positive correlations between menstrual attitudes of participants and premenstrual syndrome (r=34, p<.001), menstrual attitudes and stress (r=.40, p<.001), and menstrual attitudes and burnout (r=.16, p=.031). There were positive correlations between premenstrual syndrome and stress (r=.46, p<.001), between premenstrual syndrome and burnout (r=.35, p<.001), and between stress and burnout (r=.36, p<.001). Factors influencing burnout were premenstrual syndrome (${\beta}=.335$) and age (${\beta}=.216$), with an explanatory power of 18.0%. Conclusion: There is a need to develop and apply program for reducing clinical nurses' pre-menstrual syndrome. In addition, policies are needed to allow for menstruation leave, thereby making it legal.

Nonsan green tourism is an agricultural tourism. Visitors can participate and experience the agricultural product harvests or particular farmer's work activities. For visitors it provide natural environment and to take freshen air with new rural activities. To the residents it creates extra benefits out of the visitors green tourism. But, for the time being, the characteristic point of the tourists behavior of this tour is 'stop and pass' style in a single day. To create various contents of this tour needs develop visitors to 'stay over night' program and examine the practical methods of traditional houses as its accommodation facilities.

Our country has depended on fossil fuel very much according to the Increasing of the demand of the electric power. For instance, if the reduction and freezing caused by the warm gas in earth by the regulation of international environment happen in Korea it will bring about the result of weakness in industrial activity. As a result, it will cause many problems to compete an advanced country which wants to connect environment with the activity of industrial product in their country. The photovoltaic system outputs have peak about a half past 13 o'clock(before and after) mainly in a good weather. The output decreases rapidly from a half past 17 o'clock and PV output doesn't work at six o'clock before the sun rises. The outputs of PV system stops at that time. The frequent degree of harmonics in dwelling house which lots of people live has peak from 19 o'clock to 22 o'clock Harmonics mainly happens at least at night. In recent, many researches about power quality has been studying very hard in order to solve the question, the voltage fluctuating and harmonics as one compensator. In this paper, I suggest the algorithm which can increase the power quality as a rate of operation of this system. This algorithm proves to have effectiveness through computer simulation.

Purpose: The purposes of this study were to understand correlation of parenting stress and turnover intention of nurses, and to provide basic data for effective nursing management. Methods: Subjects included 287 nurses who had children and worked in hospitals. Data were collected through organized questionnaires from September 1st to 30th 2010. Collected data was analyzed with descriptive statistics, t-test, ANOVA, correlation analysis using PASW statistics 18 program. Results: The average score for parenting stress of the participants was 3.12 out of 5. Nurture stress was statistically different depending on age, job position, shift work, night duty and stages of family development. The average score for turnover intention of the participants was 3.34 out of 5. Turnover intention was statistically different depending on age, number of children and stages of family development. As a result of correlation analysis of parenting stress and turnover intention, turnover intention showed positive correlation with daily stress, stress caused from taking parent role and average parenting stress. Conclusion: This study indicates that parenting stress is related with turnover intention, nursing managers should make efforts to decrease parenting stress in order to reduce turnover intention of nurses.

Purpose: The purpose of this study was to review articles, thesis and dissertation on turnover intention of hospital nurses in order to identify overall trends in turnover intention of nurses and suggest strategies for reducing turnover intention. Method: Thirty research papers on turnover intention of nurses were reviewed. Result: These papers were journal articles and thesis regarding nurses who worked in general wards, intensive nursing units, and emergency rooms in hospital. The tools used to measure turnover intention were Lawler (1983), Mobley (1982), and Lee (1995), and others. Most of tools were composed of 1-11 items, with 4-7 point Likert scales. Reported reliability was .55 to .91. The mean score for turnover intention was between 2.40 and 3.85. The important results revealed that job satisfaction, organizational commitment, and stress affected turnover intention of hospital nurses. Conclusion: The findings from this review indicate that to reduce turnover intention for hospital nurses, a nurse manager should increase job satisfaction, organizational commitment, and reduce stress by developing a good culture and work climate. Moreover it is necessary to assess stress and job satisfaction of nurses, and to manage nurses' welfare, including night duty policy, salary, and career ladder.

In this paper, 1 examined role gratification and role strain of South Korean working mothers. The results show that South Korean working mothers experienced very similar level of role gratification and role strain as taking their multiple roles. The findings also show that the factors of caregiving demands, employment demands, caregiving resources, employment resources are not strongly related to role gratification and role strain. Among the 12 caregiving demand variables and employment demand variables, number of children, type of family, number of hours worked were significantly related to producing role gratification. Among the 12 caregiving demand variables, number of hours worked, number of husbands absence due to night work were significantly related to producing role strain. Among the 8 caregiving resources, participants satisfaction due to income contribution, look to make a purchase new electric home appliances were significantly related to produce role satisfaction. Among the 8 caregiving resources, number of family support policies in the husbands workplace, participants satisfaction due to income contribution were significantly related to producing role strain.
