This paper explores variables that influence the prediction of OTT service experience and free(AVOD)/ paid(SVOD) service use. Research results showed that five variables such as gender, age, personal income, household composition, and e-commerce use experience had a significant impact on identifying OTT service experience and whether to use free or paid services. Also, it was found that the probability of using SVOD increases as they prefer news and drama genres and use OTT services for more time. In summary, those who are relatively young, have a high personal income, and are more adapted to digital environments such as e-commerce are more likely to use SVOD.

This paper aims to predict Busan's regional product and employment using the logistic regression models and machine learning models. The following are the main findings of the empirical analysis. First, the OLS regression model shows that the main industries such as electricity and electronics, machine and transport, and finance and insurance affect the Busan's income positively. Second, the binomial logistic regression models show that the Busan's strategic industries such as the future transport machinery, life-care, and smart marine industries contribute on the Busan's income in large order. Third, the multinomial logistic regression models show that the Korea's main industries such as the precise machinery, transport equipment, and machinery influence the Busan's economy positively. And Korea's exports and the depreciation can affect Busan's economy more positively at the higher employment level. Fourth, the voting ensemble model show the higher predictive power than artificial neural network model and support vector machine models. Furthermore, the gradient boosting model and the random forest show the higher predictive power than the voting model in large order.

Objectives : The purpose of this study was to provide some information on the development of oral health care programs geared toward diabetics and ways of promoting their oral health. Methods : The subjects in this study were 586 diabetics who were selected from the 2009 third-year raw data of the 4th(2007~2009) National Health & Nutrition Survey. The data were analyzed with the statistical package SPSS 12.0 to grasp the influence of their sociodemographic characteristics and oral health behaviors on the presence or absence of periodontal diseases and missing tooth. Results : 1. Periodontal diseases were twofold more prevalent among the men than the women(p<0.01). By age, those who were in their 60s had 1.11-fold more periodontal diseases than those who were in their 70s and up(p<0.05). 2. The men and women were similar to each other in the number of missing tooth. By age, the number of missing tooth got smaller in proportion to decrease in age. By income, the number of missing tooth was 1.48-fold larger among the patients who earned an income of one million won or less than those who earned an income of two million won or more(p<0.01). Conclusions : The above-mentioned findings suggest that prospective cohort studies should be implemented to present prediction models of periodontal diseases and diabetes instead of merely sticking to cross-sectional studies. And oral health programs should be developed based on the findings of cohort studies to encourage diabetics to care about their oral health, and in which way they should be helped to promote their oral health should carefully be considered.

Recently, Korean government documented the plan to cope with the situation related to rich pensioners of Basic old-age pension. The purpose of this paper is to verify that how many rich pensioners are existing and to evaluate government reform plan's validity and effect. Main results are as follows; firstly, if the definition of rich pensioners is on the top 10%, the proportion of them would form 2.9% of total. And then, an amount of expenditure for them is only 2.6% of total. Secondly, in terms of disposable income, debt, and transfer income from child, the household who would be applied by government's plan is not richer than other household who is in the same living standard. And then, if the government's plan enforced, the effect might be very small. Lastly, the plan of government will discriminate against persons who support their parent. As a result, Basic old-age pension will be worsen. This paper should underline that the government's reform is only the 'hidden' retrenchment strategy in order to introduce a standard of the obligation to support own parent in the state without scientific prediction and serious discussion of negative public opinion. That is why, this is the same as the 'Trojan Horse'.

Objectives : This study was to examine factors affecting the job satisfaction of dental hygienists. Methods : The subjects in this study were dental hygienists who worked at dental hospitals, dental clinics and general hospitals in the city of Gwangju. A survey was conducted by mail from January 2 to March 2, 2007. Out of the collected data, 208 answer sheets were analyzed. Results : 1. The dental hygienists investigated got a mean of 3.20 on job satisfaction. Among the job satisfaction factors, relationship with patients ranked highest(3.79), followed by relationship with colleagues(3.62), working environments(3.39), future prospects(3.30), professional status (2.89), pay(2.82) and required workload(2.58). 2. Regarding links between general characteristics and job satisfaction, the older dental hygienists were more satisfied with professional status, pay, required workload and relationship with patients. By marital status, the married dental hygienists expressed better satisfaction at professional status than the unmarried ones. By education, those who were receiving college education or received the same or higher education were more gratified than the junior college graduates. By the total length of career, the dental hygienists whose length of career was longer were more gratified with professional status, future prospects and relationship with patients. By workplace, the dental hospital workers were more satisfied with working environments, and the general hospital employees were more gratified with pay. The dental hospital employees were better satisfied with future prospects as well. As to the impact of the length of career at the current workplace, there was a tendency that those who worked at their current workplaces for a longer time expressed better satisfaction with professional status, pay and relationship with patients. By monthly mean income, the larger income earners had a tendency to be better gratified with professional status, pay and relationship with patients. 3. The general characteristics that were selected as independent variables were identified as the factors that exercised an influence on the job satisfaction of the dental hygienists and made an about 14.0% prediction of it. Out of those factors, the total length of career and monthly mean income had a statistically significant impact on that. Conclusions : The above-mentioned findings suggested that out of the seven job satisfaction components, they gave the lowest marks to satisfaction level with pay. As a result of making a multiple regression analysis, it's found that job satisfaction was under the influence of the total length of career and monthly mean income. Therefore there should be an improvement in the pay system in order to boost the job satisfaction of dental hygienists, and they should be paid properly in accordance with total length of career.
