This study aimed to investigate predictors of turnover intention of home visiting nurses at 16 public health centers in Busan. There are two groups of independent factors: non-work related(i. e., age, educational level, working duration as nurses in hospitals, and certificate), and work related factors(i. e., working duration as nurses in public health centers, working duration as home visiting nurse, position, number of households visited per week, workload, cooperation among staff, support by supervisors, supply of vehicles, and supply of materials). Data were collected with self-administrated questionnaires which consisted of 4 items of non-work related factors, 9 items of work related factors, and 1 item of turnover intention to other department. Data were analyzed using an univariate logistic regression and multiple logistic regression. According to the results, heavy workload (Yes vs No, OR=4.31, $95\%$ CI=1.16-16.04) was the most powerful predictor on the turnover intention. In conclusion. this result was similar to those of other studies on the predictors of turnover intention of clinical nurses at hospitals. To decrease the turnover intention among home visiting nurses at public health centers in Busan, alleviating the workload is needed.

E-Government is an administrative innovation that utilizes information technology and is the most powerful means to strengthen government competitiveness. At this moment, countries around the world are continuously improving government competitiveness by continuously implementing government innovation through the implementation of e-Government. Many scholars argue that e-Government should be changed in response to the Fourth Industrial Revolution. Therefore, Korea adopted the government 3.0 instead of the e-Government and promoted the information policy. But the result was a failure. Korea was once a leading country in e-Government, but now it is falling due to government 3.0. The reason can be analyzed in various ways. First of all, over the past decade, Korea's e-Government has been neglected without obtaining the permanence of policy. And the Korea government pursued a new strategy under the name of disconnecting from the past and lost policy permanence. Therefore, future information policy, especially e-Government policies, should be pursued from a politically neutral point of view. The lesson of government 3.0 failure in Korea is clear. Regardless of the government's replacement & regime change, the information policy should be pursued with consistency.

The purpose of this study was to investigate parenting stress changes in both continuous working and continuous non-working mothers after the birth of their first child and their relationships with the cognitive variables about child-rearing, using the 3rd Panel Study on Korean Children(PSKC) by the Korea Institute of Child Care and Education(KICCE). The results revealed that the parenting stress of the non-working mothers was higher than the stress experienced by the working mothers. The increase in stress was only found both groups between the second year and the third year of childbirth. The total explanatory power of the knowledge, values and expectations regarding their children saw stress increase for the working mothers, but saw it decrease for the non-working mothers. Finally, the emotional value surrounding parenthood was the most powerful variable for both groups, with the exception of the non-working mothers' stress, as experienced in the first year.

Purpose: The purpose of this study was to examine the relationship of psychosocial wellbeing status and self leadership with job satisfaction of fire officers. The effects of these variables on job satisfaction were also examined. Methods: The study design was a descriptive, correlational design. For this study, data were collected from 189 fire officers in B metropolitan city, K and Y cities. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, and multiple regression analysis with SPSS 21.0 program. Results: The results showed that job satisfaction had a significant correlation with psychosocial wellbeing status (r=-.38, p<.001) and self leadership (r=.26, p<.001). Psychosocial wellbeing status had a significant correlation with self leadership(r=-.47, p<.001). Multiple regression analysis for job satisfaction revealed that the most powerful predictor was psychosocial wellbeing status followed by self leadership. Pychosocial wellbeing status, self leadership, age, marital status and current job task career explained 25.0% of the variance in job satisfaction. Conclusion: Findings indicate that various factors are related to the job satisfaction of fire officers. Based on the results of this study, further development and application of programs to improve fire officers' job satisfaction are needed.

In order to treat the wastewater containing organic compound, pre-treatment system connected with MSP(molecular separation process) was investigated. With the aim of selecting an optimum process of Fenton's oxidation, removal efficiency of each process in the optimum reaction condition was recommended. The $Fe/H_{2}O_{2}$(ferric sulfate to hydrogen peroxide)reagent is referred to as the Fenton's regent, which produces hydroxyl radicals by the interaction of Fe with $H_{2}O_{2}$. The powerful oxidizing ability and extreme kinetic reactively of the hydroxyl radical was well established. Increasing dosage of $Fe/H_{2}O_{2}$ increased removal efficiency as molar ratio of $Fe/H_{2}O_{2}$ between 0.2 and 2.5. Optimum dosage of molar ratio was 1. The removal efficiency for reaction condition was increased as pH decreased when the molar ratio of $Fe/H_{2}O_{2}$ was 1.7. Fenton's oxidation was most efficient in the reaction time 35 min for complex wastewater. Also, coagulation aid experiments using kaolin resulted in 3% of kaolin dosage.

Altitudinal patterns of plant species richness and the effects of area, the mid-domain effect, climatic variables, net primary productivity and latitude on observed richness patterns along the ridge of the Baekdudaegan Mountains, South Korea were studied. Data were collected from 1,100 plots along a 200 to 1,900 m altitudinal gradient on the ridge. A total of 802 plant species from 97 families and 342 genera were recorded. Common and rare species accounted for 91% and 9%, respectively, of the total plant species. The altitudinal patterns of species richness for total, common and rare plants showed distinctly hump-shaped patterns, although the absolute altitudes of the richness peaks varied somewhat among plant groups. The mid-domain effect was the most powerful explanatory variable for total and common species richness, whereas climatic variables were better predictors for rare plant richness. No effect of latitude on species richness was observed. Our study suggests that the mid-domain effect is a better predictor for wide-ranging species such as common species, whereas climatic variables are more important factors for range-restricted species such as rare species. The mechanisms underlying these richness patterns may reflect fundamental differences in the biology and ecology of different plant groups.

The major purpose of the present research was to examine the effect of adolescents's perception of parents' marital relationship and attachment with their parents on school adjustment. This study also tried to investigate the inter-relationship among related variables, and the differences in the level of school adjustment according to adolescents' general characteristics. The participants were 355 middle and high school students who lived in Chollabuk-Do province. The major results of this research were as follows. First, there were significant differences in the level of school adjustment according to sex, age, and grade point. average That is, the level of school adjustment was higher for males, for older adolescents, and for those recording higher grade point, than for females, for younger, and for those recording relatively lower grade point. Second, parents' marital relationship was positively correlated with positive aspects of attachment with their parents(i.e., communication and trust), and with school adjustment. but negatively correlated with negative aspect of attachment(i.e., alienation from their parents). Finally, multiple regression analyses were performed to analyze the relative significance of the related variables influencing on school adjustment after controlling the effect of sex, age, and grade point. It was found that communication with fathers was the most powerful predictor of school adjustment, while attachment with mothers was not found to be a significant predictor of school adjustment.

The purpose of this study was to investigate the effect of family of origin experiences on self-esteem and marital conflict among married men and women. For this purpose, a survey was conducted using self-administered questionnaires with 311 married men and women. The results of the study were as follows: First, men and women's family of origin experience(family of origin health, parents' marital conflict, triangulation) were correlated with self-esteem and marital conflict. Second, results of multiple regression analyses showed that men and women's self-esteem was most powerful predictors of marital conflict. Finally, men's family of origin experiences(family of origin health, parents' marital conflict, triangulation) had a direct effect on marital conflict, and family of origin health had a indirect effect through men's self-esteem on marital conflict. Women's parents' marital conflict, triangulation had a direct effect on marital conflict, and family of origin health had a indirect effect through women's self-esteem on marital conflict.

The purpose of this study was to investigate the selected predictors of the health promotion behavior of the elderly in Kangseo-ku, Kangnam-ku, Seoul. The study used an ecological perspective approach in that a microsystem (i.e. self-esteem, locus of control, introversion-extraversion and socio-demographic characteristics), and the environment such as a mesosystem (i.e. marriage satisfaction) and a macrosystem (i.e. social support, participation of social activities, social image of the elderly, social attitude of the elderly) were explored. A structured questionnaire was used to interview a sample of 188 elderly. Hierarchicai regression analysis yielded the results that the magnitude of the importance of the microsystem was found to be larger than any other systems investigated. The most powerful predictor of the health promotion behavior of the elderly was 'age', followed by 'participation of social activities', 'education', 'social support', 'locus of control', 'marriage satisfaction', and 'sex'. The research model accounted for $55\%$ of the health promotion behavior of the elderly.
