  • The purpose of this study was to investigate the factors related to problem drinking in male workers according to occupational classes. Data were derived from the 2012 Korean National Survey on male workers. A total of 391 office workers, 707 manufacturing workers, and 309 service workers participated in this study. Data were analyzed using Rao-Scott $X^2$-test, simple and multiple logistic regressions. Problem drinking was defined as ${\geq}8$ points in the Alcohol Use Disorders Identification Test. The problem drinking rates were 45.1% in office workers, 39.1% in manufacturing, and 42.3% in service. In office workers, the factor related to problem drinking was only smoking. In manufacturing workers, the factors related to problem drinking were spouse, smoking and prevalence of Diabetes. In service workers, the factors related to problem drinking were age and smoking. Therefore, different intervention should be developed for each occupational class in order to manage the problem drinking in male workers.

  • [purpose] This study was conducted to identify how a hospital's outsourcing workers' QWL influences Turnover Intention and to determine Dual Commitment cause any discrepancies in regards to the link between QWL and Turnover Intention. [Methodology/Approach] The study is based on 254 survey sheets answered by outsourcing employees working at general hospitals with more than 300 beds in Seoul and the methods of analysis used are as follows: reliability analysis, correlation analysis, multiple regression analysis, and hierarchical regressions analysis. [Findings] The study results First, analyzing how different types of QWL (individual, organizational, managemental) influence Turnover Intention, R2 turned out to be 30.7% and organizational factors and managemental factors show a statistically significant difference. In addition, organizational and managemental factors have negative effects on Turnover Intention while that of organization factors has a bigger influence. Second, verifying regulation effects of Dual Commitment in regards to the link between QWL and Turnover Intention, it is learned that Dual Commitment (hiring firm) has no regulation effects on the link. However, it does have a regulation effect on the link between QWL (managemental) and Turnover Intention. Moreover, after verifying regulation effects of Dual Commitment (client's firm), it is learned that it has regulation effect on the link between QWL (organizational and managemental) and Trunover Intention. [Practical Implications] In conclusion, lower Turnover Intention, it is necessary to impose tasks that suit the employees' competence and to encourage efficiency throughout clear communications and accurate directions.

  • The purpose of this study was to identify men's beauty service markets based on socio-cultural appearance attitude and to compare their satisfaction and intention to revisit beauty service. The study was done by survey method. Data of three hundred men aged from 20's to 40's were collected by on-line survey. Descriptive analyses, factor analyses, cluster analyses, Duncan tests, multiple regressions, and path analyses were applied. The results are as follows: First, five factors were found for men's socio-cultural attitude for their appearance. They were high involvement in appearance, social appearance, appearance satisfaction, appearance comparison and low involvement in appearance. Second, cluster analysis based on socio-cultural attitude produced three customer groups such as high involvement, social concern & satisfaction, and low involvement. Third, customer groups showed significant differences in some demographics and some items of service dimensions, which resulted in significant differences in satisfaction, and intention to revisit beauty shop services. A high involvement group was composed of young and unmarried men with more frequent visit to beauty shop service. In general, both the high involvement and the social concern & satisfaction groups showed higher evaluations than the low concern group in some of service items, level of satisfaction, and intention to revisit. In conclusion, attitude on their appearance could be useful factors in segmenting men's beauty service market. Levels and types of beauty shop service should be differentiated among consumer markets.

  • Objectives: The purpose of the study is to investigate the factors influencing on self-esteem, major satisfaction, and career identity. Methods: A self-reported questionnaire was filled out by 389 dental hygiene students in three colleges located in Metropolitan area. The questionnaire consisted of 5 questions of general characteristics, 10 questions of self-efficacy, 18 questions of major satisfaction, and 13 questions of career identity by Likert 5 scale. Cronbach's alpha was 0.92 in self-efficacy, 0.90 in major satisfaction, and 0.88 in career identity in the previous studies. Cronbach's alpha in this study was 0.911 in major satisfaction, 0.840 in self-efficacy, and 0.8090 in career identity. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, and stepwise multiple regressions. Results: The score was 3.47 in self-esteem, 3.79 in major satisfaction, and 3.03 in career identity. There were significant differences in self-esteem and major satisfaction based on grade, motivation for entering college, and clinical practice satisfaction. In case of career identity, there were significant differences based on characteristics, motivation for college choice, and clinical practice satisfaction. There was a positive correlation between negative self-esteem, positive self-esteem, general satisfaction, awareness satisfaction, curricula satisfaction, interpersonal relation satisfaction, and career identity. The influencing factors on career identity were aptitude, interest, self-esteem, and major satisfaction in order(p<0.001). Conclusions: The career identity is closely related to self-esteem and major satisfaction. It is desirable to open a variety of education courses and to develop systematic and practical programs to the students in order to improve the career identity.

  • In this study, a various rainfall-runoff modelling approaches have been applied to the runoff response of flood hydrograph in three experimental watershed of the western part of korea. Mathematical models of runoff response also have been studied including linear system theory based on modeling techniques. Eight models were operated at the five water level gauging stations and the parameters of each model were computed by the Rosenbrock's hill climbing method to minimize the objective function. For the parameter verification of the models, a different complex rainfall-runoff event was selected in the same of the three river basins and derived IUH of the each model could be calibrated. Furthermore multiple regressions of the logarithmic transformation method between model parameters and catchment characteristics were studied in the selected five station.

  • BACKGROUND/OBJECTIVES: Sustainable practices in foodservice organizations including commercial and noncommercial ones are critical to ensure the protection of the environment for the future. With the rapid growth of the foodservice industry, wiser usage of input sources such as food, utilities, and single use packaging should be reconsidered for future generations. Therefore, this study aims to investigate the customer's perceptions on sustainable practices and to identify the relationship among sustainable practices, social contribution and purchase intention. SUBJECTS/METHODS: The study was conducted using content analyses by reviewing articles on sustainable food service practices published domestically and abroad. Thereafter, data were collected with a face-to-face survey using a questionnaire and analyzed with factor analyses and multiple regressions. RESULTS: Sustainable practices classified with factor analysis consisted of 6 dimensions of green food material procurement, sustainable food preparation, green packaging, preservation of energy, waste management, and public relations on green activity, with a total of 25 green activities in foodservice operations. Consumers were not very familiar with the green activities implemented in the foodservice unit, with the lowest awareness of "green food material procurement (2.46 out of 5 points)", and the highest awareness of "green packaging (3.74)" and "waste management (3.28). The factors influencing the perception of social contribution by foodservice organizations among 6 sustainable practice dimensions were found to be public relations on green activity (${\beta}=0.154$), waste management (${\beta}=0.204$) and sustainable food preparation (${\beta}=0.183$). Green packaging (${\beta}=0.107$) and the social contribution of the foodservice organization (${\beta}=0.761$) had strong relationships with the image of the organization. The purchase intentions of customers was affected only by the foodservice image (${\beta}=0.775$). CONCLUSIONS: The results of this study suggest that sustainable practices by foodservice organization present a good image to customers and increase the awareness of valuable contributions that benefit the customer as well as the community.

  • The increasing interest in the use of Automated Speed Enforcement (ASE) systems in Korea enables to enforce speed violation by National Police Agency. We have analyzed the mechanism of ASE systems on traffic safety throughout Korea. 1 The data collected on a 2km road-section of each 32 ASE stations during one rear period indicate significant safety improvement. The results were (a) a decrease in the total number of accidents of 28%, (b) a decrease in the number of fatalities of 60%. 2. The study also that ASE systems are effective to reduce average speed, speed variance, and short headway. 3. Based on the operational data collected at 15 locations, an aggregate safety prediction model is proposed as a multiple regressions form. The primary operational variables that appear to affect the frequencies of accident are : average speed, speed variance, and the number of vehicles exceeding 30km/h of posted speed limit.

  • This study aimed to identify the self-rated health and its associated factors of the elderly. Study subjects were community-dwelling elderly of 60 or more. Survey was done by using questionnaire including general characteristics, lifestyle, and health related variables. Blood pressure, anthropometric variables, lipid profiles, and fasting glucose were checked. Descriptive statistics showed that good self-rated health was 78.2% in the elderly. Multiple logistic regressions revealed that good self-rated health was associated with disease(OR:10.83, 95% CI:2.47-47.43), depression(OR=2.50, 95% CI=1.20-5.18), and exercise(OR=3.01, 95% CI=1.40-6.47). Therefore, health promotion program considering associated factors of self-rated health should be developed.

  • There have been numerous studies in Korea and other countries of which the major hypotheses are identifying and dearibing the conditions under which the value of children has been formed. The present study proposes to view the formation of the value of children as a correlate of family's consumption-saving and work4eisure behavior pattern. The objectives of the proposed study are to identify the socio-economic and demographic factors determining the family's consumption-saving and work-leisure behavior pattern and to analyse the relationship between the value of children and this behavior pattern. The conceptual framwork of the analysis is that an individual family's socio-economic and demographic factors influence and shape the consumption-saving and work-leisure behaviors and these behaviors in turn influence and reflect the correlates and proximate determinants of the family'sfertility. In this paper, regression model is used to analyse the hypothesized relationship among the various variables. The regression methods used are first and second stage multiple regressions. In addition, MONOVA has been used to show the interactions. Data used are collected from the government publicactions. The major findings from this study are as follows: As the living Standard improves, n individual family's consumption of necessities and its working hours decline, while savings and leisure activities increase. The phenomena result in the fertility reduction as can be seen in the more developed conntries. Child-bearing and rearing activities are found to be the important component to determine the condumption-saving and work-leisure activies. The married women's labor participation, and the investment in education and health are also found to be the factors reducing fertility rate.
