The purpose of this study is to analyze the changes in job satisfaction and turnover intention according to the level of Emotional labor and the mediating effect in dental hygienists. The survey was performed from April, 2016 to November, 2016 against 300 dental sanitarian working in Daejeon and Daegu district and a total of 292 people's data was made an object for final analysis. As a result of it, the emotional labor and exhaustion showed positive relationship and thus as the emotional labor is high, exhaustion was high(P<0.1), and the job satisfaction was negative and thus as the emotional labor is low, the job satisfaction was high(P<0.1) Also, the emotional labor in the turnover intention was positively related and thus as the emotional labor is high, the turnover intention was high(P<0.5). Thus, a scheme to lower the job stress and the exhaustion experience degree and increase the compensation and welfare benefits in order to solve the emotional labor of the dental sanitarian.

Korea's spatial information companies have been supported by the government due to overcome the weak global competitiveness. This research examines possible causality between the request from the company and the policy support by the government. Structural equation model is used to analyze the recognized competitiveness and the supporting policy. The analysis result shows no statistically significant causality between the company's request and government's support. In other words, the current policies including subsidies, tax incentives, national certificates, and information channels do not impact the global competitiveness of a spatial information company. This research concludes that it is necessity to identify actual weaknesses of the company and to review the efficiency of the supporting policies to overcome those identified weaknesses.

The purpose of this study was to analyze the association among high school students' self-efficacy, self-resilience, and oral health promotion lifestyle, identify relevant factors, and provide basic data for oral health promotion programs. The subjects of this study were 287 students, research tool was the structured, anonymous, self-administrated questionnaire. The data were analyzed by SPSSWIN 18.0, Pearson correlation and Hierarchial multiple regression et al. Significant positive correlation was found between self-efficacy and self-resilience and between self-efficacy and oral health promotion lifestyle and positive correlation was also found between self-resilience and oral health promotion lifestyle. Mother's education, past oral health behavior, self-efficacy, and self-resilience affected oral health promotion lifestyle, with the explanatory power of 32.3%. Since self-efficacy and self-resilience are correlated with oral health promotion lifestyle, it is necessary to develop a plan for activating oral health education with the objective of improving the combination of these factors.

Contingency tables are used to compare counts of n-grams to determine if the n-gram is a true collocation, meaning that the words that make up the n-gram are highly associated in the text. Some statistical methods for identifying collocation are used. They are Kulczinsky coefficient, Ochiai coefficient, Frager and McGowan coefficient, Yule coefficient, mutual information, and chi-square, and so on. But the main problem is that these measures are based ell the assumption of a nor-mal or approximately normal distribution of the variables being sampled. While this assumption is valid in most instances, it is not valid when comparing the rates of occurrence of rare events, and texts are composed mostly of rare events. In this paper we have simply reviewed some statistics about testing association of two words. Some randomization tests to evaluate the significance level in analyzing collocation in large corpora are proposed. A related graph can be used to compare different lest statistics that ran be used to analyze the same contingency table.

This study intended to explain the relationship between climate change and magnetic susceptibility of estuarine sediment. Data of OSL dating and magnetic susceptibility from estuarine tidal sediment were compared with various climate change data. During the last Holocene, the intense of magnetic susceptibility related with weaker Siberian High and stronger Asian Summer Monsoon. It is explained that high precipitation and runoff made much fluvial sediment input to the estuary. From the early to mid Holocene, there is no clear relationship between climate change and MS because of the much coastal sediment input caused by rapid sea level rise and the formation of upland soil and coastal marsh. These results contribute to reconstruct paleo-environmental changes of west coast of Korea, in the way of using benefit of ubiquitous estuarine tidal flats and relatively useful magnetic susceptibility methodoloy.

This study examines empirically on relevance between bank performance and IC(Intellectual Capital) in the field of banking sector in Korea. IC is measured by VAIC(Value Added Intellectual Capital) and VAIC consists of HCE(Human Capital Efficiency Coefficient), CEE(Capital Employed Efficiency Coefficient) and SCE(Structural Capital Efficiency Coefficient). Main results are as follows. First, the effects of IC(Intellectual capital) on banks performance show significant (+) effect on the performance of banks. Second, Human capital and bank size shows the significant effect on the banks financial performance but SCE, CEE, and other variables didn't show it. As a concluding remark, IC(Intellectual capital) is very helpful for banks to go forward financially to get information and knowledges easily. This study help stakeholders and investors assess the value creating potential of banks and policy makers to implement policies for performance establishment of a Korean banking sector.

To generate individualized and adaptive course, it's required to have the foundation structure in which learning objects are connected with each other with logical relevances. Each learner can have peculiar learning path at each point of time of learning through the logical relevancy between those learning objects and various links, considering individual learner. The purpose of this study is to design a learning object-basis individualized learning system structure, considering semantic sequencing by learning task types. It is our understanding that the individualized learning system design model of this study, considering the relevancy between learning objects, can be a fresh trial to accommodate semantic learning and true educational spirits in e-Learning at this point of time when criticism, such as the learning object based course design is simply a collection of meaningless objects, etc., is becoming influential.
