This study was conducted to examine the oral health awareness, needs of dental treatment and the oral and maxillofacial pains targeting pneumoconiosis patients of care hospitals for the purpose of providing basic data for preparing a plan to improve the oral health of patients plagued with pneumoconiosis. As the subjects of survey, total 120 patients who have agreed to the research among the patients of three care hospitals, were enrolled between March and July in 2015. As the result of the study on the factors that influence the oral health perception, it was verified that the persons of an average monthly income of 2 million won or more, were shown to have significantly better oral health awareness than the subjects of monthly earning of less than 2 million won (p<0.05), thus showing that the oral health awareness by the people of monthly income of more than 2 million won, was 0.77 times higher compared to the others. Therefore, in order to improve the oral health awareness of pneumoconiosis patients, the economic stability of the patients should be taken into account as a priority when examining the oral health policy decisions and it was recommended that the survey and research on the oral health of patients with pneumoconiosis can be done in amore systematic manner.

In this paper We measured average earnings differentials between the government and the private sector, the degree of earnings inequality within each sector, and estimated net earnings differentials between the public and private sector in 1982, 1985, 1990, 1995 and 1998, respectively. According to our estimation results, the public servants in Korea are being more paid than the private sector on the average, and have been enjoying higher net wage premium after controlling variables such as education level, job experience and occupation, etc. In terms of earning inequality within each sector, the public sector was proven to have very narrow earnings differentials between the top and the bottom, compared to quite large differentials in the private sector. Wide recognition that the public servants' compensation is lower in Korea seems quite wrong. The problem to be resolved is the earnings standardization in the public sector and the strong trend toward more equality in recent years. We recommend that the wage gap between the higher rank and the lower rank should be extended, and employment flexibility within the lower positions or ranks of the bureaucracy should be enhanced.

Most nancial preference methods for market risk management are to estimate VaR. In many real cases, it happens to obtain the VaRs of the univariate as well as multivariate distributions based on multivariate data. Copula functions are used to explore the dependence of non-normal random variables and generate the corresponding multivariate distribution functions in this work. We estimate Archimedian Copula functions including Clayton Copula, Gumbel Copula, Frank Copula that are tted to the multivariate earning rate distribution, and then obtain their VaRs. With these Copula functions, we estimate the VaRs of both a certain integrated industry and individual industries. The parameters of three kinds of Copula functions are estimated for an illustrated stock data of two Korean industries to obtain the VaR of the bivariate distribution and those of the corresponding univariate distributions. These VaRs are compared with those obtained from other methods to discuss the accuracy of the estimations.

Income is a vital aspect of economic life. Knowing what their income will help people create budgets that allow them to pay for their living expenses. Income data is used by banks, stores, and service companies for marketing purposes and for retaining loyal customers; it is a crucial demographic element used at a wide variety of customer touch points. Therefore, it is essential to be able to make income predictions for existing and potential customers. This paper aims to predict employment earnings or income based on history, and uses machine learning techniques such as SVMs (Support Vector Machines), Gaussian, decision tree and DCNNs (Deep Convolutional Neural Networks) for predicting employment earnings. The results show that the DCNN method provides optimum results with 88% compared to other machine learning techniques used in this paper. Improvement of the data length such PCA has the potential to provide more optimum result.

The study is aimed to analyze the influence of FTA(Free Trade Agreement) between Korea and Japan on tourism and to suggest ways to increase tourists exchange between them by considering countermeasures of Korea's tourism based on the analysis and deriving political significance. The results of the study showed that the expected effects of FTA between Korea and Japan on tourism would overall be positive. There would be increases in employment and a higher rate of foreign-exchange earning, which plays a critical role in the cash flow. Therefore the government is required to prepare for several political measures as follows. First, ways to promote investment in tourism have to be established in a systematic way for FTA. Second, restructuring of tourism has to be considered seriously for tourism to be a high value-added industry after FTA. Third, the tourism information industry needs to be included in the tourism promotion act to promote e-tourism using information technology. In addition to this, an expansive cluster strategy needs to be developed, which relates tourism to other industries like culture and movies and to find ways to re-locate and re-educate manpower currently engaged in the tourism industry. Though the study investigated the influence of FTA on tourism through a practical analysis, it was restricted only to Korea. So the influence of FTA between Korea and Japan on the tourism of Japan should be included in further study. Furthermore, in subsequent studies the CGE(Computable General Equilibrium) model will be applied for objective analysis of the effects. Or measuring the ripple effect with multinational inter-industry relation table will be made for the study to make practical contributions to the development of government policy.

This study analyzes the effect of separation of dispensary from medical practice on hospital management performance. The results are as follow. The earning ratios of large size hospitals become deteriorated significantly after the separation of dispensary. The growth ratios of revenues from inpatient were unchanged, but the growth ratios of revenues from outpatient of large and middle size hospitals were decreased significantly. Hospitals can't sell the medicines to the outpatient after the separation of dispensary, but they can do to the outpatient. The labor cost ratios of small and large size hospitals are increased significantly after the separation of dispensary. There are two reasons for increase of labor cost ratios. One is the decrease of material cost ratio. The other is the increase of doctor's salary. The material cost ratios of every size hospital are decreased significantly after the separation of dispensary. Because medicines costs of outpatients are decreased. The labor cost and doctors' salary per patient of middle and large size hospitals are increased significantly after the separation of dispensary. And average treatment fees per day of inpatients of middle and large size hospitals are increased significantly after the separation of dispensary. But those of outpatients are decreased significantly. Average numbers of outpatients per bed of small and large hospitals are decreased significantly after the separation of dispensary. And average numbers of inpatients per bed of large hospitals are decreased significantly. In summary, as a consequence of separation of dispensary from medical practice, management performances of large size hospitals become deteriorated significantly.

This study was to find out the effects of out-of-class environmental experience learning on elementary students' environmental literacy. For this study, we developed and applied environmental education program utilizing out-of-class facilities and ecological park for the 5th-grade students. The subjects of this study were the 5th grade students of an elementary school located in Si-hung city. The study was carried out for two groups, an experiment group of 29 students and control group of 29 students. The education program using out-of-class environmental experience learning was provided to the experiment group while lecture-oriented education program was provided to the control group. The questionnaire used in this study to assess the environmental literacy of the study objects consists of 41 questions under 4 domains (knowledge, emotion, skill, behavior). After observing and analyzing the effects of out-of-class environmental experience learning on students' environmental literacy, we found that the program using the out-of-class environmental experience learning posed greater impacts than lecture-oriented program. By domains, environmental literacy in 3 domains illustrated positive improvement. In particular, skill domain illustrated much more improvement in environmental literacy. But, domain of behavior didn't illustrated improvement in environmental literacy. The result of this study signified that the out-of-class environmental experience learning has positive and effective impact on the environmental literacy. And out-of-class environmental experience learning is more suitable to improve the skill domain of the environmental literacy than lecture-oriented learning. But, it is couldn't improve the domain of behavior. Therefore, in order to improve behavior domain, the program must apply with effective evaluation and home training.
