In this study, electrical resistivity tomography (ERT) were conducted to find the mineralized zone at the Geumpung mine in Dojeon-ri, Susan-myeon, Jecheon-si, Chungcheongbuk-do. The deviation of the inclined borehole was measured to obtain the exact positions of the electrodes for correcting apparent resistivity values from ERT. Geophysical loggings such as resistivity and natural gamma were conducted to obtain the properties of the material near the borehole. Measurements of the physical properties of the cores, such as porosity, water content, density, susceptibility, resistivity were performed to analyze the correlation between physical properties and resistivity. Grade analysis for core sample was also conducted to identify relationship between grade and resistivity. Rock property analysis shows that the resistivity is more dominated by susceptibility and grade than by porosity and water content in the mineralized zone. The results of ERT are well consistent with geophysical logging data and geologic column. So ERT is powerful method to identify conductive mineralized zone.

This study is to investigate the impact of the social capital on organization trust, and the impact of the organization trust on recommendation intention, and turnover intention. And by this it is also to integrally analyze through what route social capital affects the recommendation intention and turnover intention. An actual analysis through covariance structural equation model was made targeting the members of small and medium sized manufacturing companies. The results of the actual analysis showed that the relational dimension in the social capital had an positive(+) and the most pervasive effect on the organization trust. Relational dimension refers to the formation relationships among members and has a significant value in the interaction in the relation between subordinates and superiors, between colleagues, and between departments. Secondly, the cognitive dimension in the social capital was revealed to have no significant effect on the organization trust and structural dimension was revealed to have a positive(+) effect on the organization trust. Structural dimension refers to the capital value which shows itself in the social network and relationship existing between the members and is formed through building the best network within an organization. Thirdly, organization trust was revealed to have a positive(+) impact on the recommendation intention and to have a negative(-) impact on the turnover intention. Finally, the summary, implications, limitations, and future research direction of this study were presented.

The purpose of this study is Big Five personality factors of personality type on career behavior, that is, entry to the unsafe first job in Korean university students. To accomplish this research objective, this study collected data from 500 students in three universities and two colleges located in the Chungcheong region. Among 350 questionnaires, 342 copies were used for a final analysis. In order to analyze the survey data, statistical package program SPSS/WIN 18.0 was utilized and statistical techniques such as basic statistical analysis, factor analysis, Cronbach's alpha, correlation analysis, and multiple regression analysis were used. The results obtained in this study can be summarized as follows. The extraversion personality and agreeableness personality of college students has a significant effect on the entry to the unsafe first job in the positive direction. On the other hand, the neurotic personality and openness to experience has a significant effect on the entry to the unsafe first job in the negative direction. However, the integrity personality of college students was not statistically significant. Finally, based on the empirical results we suggested several theoretical and practical implications.

To investigate knowledge and attitude of parents about early childhood caries and dental caries prevention, a questionnaire survey was conducted on 247 parents of children who had oral screening experience among 3 to 5 years old children in 3 kindergartens in Jeonju city. A total of 220 completed questionnaires were selected for final analysis. The overall perception of the parents about oral health of the children was 82.3 points (10.7 / 13) in terms of 100 points. There were statistically significant correlations between maternal age (p = 0.027), maternal education level (p = 0.002), household monthly income (p = 0.000) and maternal oral health knowledge level. The main source of oral health information was 'dentist and dental hygienist'(83.6%) followed by 'Web search'(22.3%). Compared with the previous studies, the level of knowledge of parents about oral health of the children was improved. However, in order to raise awareness of the parents about the poorly assessed items in this study, it is necessary to increase the participation rate by advertising the national dental screening program for infants and children and make efforts to improve the quality of oral health education in screening.

In the previous studies on co-constructing scientific models, students have had various difficulties in constructing their models. As an alternative to compensate for these problems, we introduced smart devices in the modeling process and examined its roles. 60 students from two classes in the fifth grade of an elementary school in Seoul had classes to make up the solar system model in a small group using the smart devices and we examined the roles of smart devices in their classes. The result is as follows; First, students were able to generate their scientific model through various functions of smart devices throughout the modeling process. In particular, smart devices provide highly descriptive and authoritative information that meets the needs of students as well as the opportunity to observe the planets from various perspectives. Moreover, they were not only able to express their models easily as they wanted to express them, but also were able to receive feedbacks from various agents. In order for these smart devices to function properly in the co-construction of scientific models, it is necessary to improve the related environment as well as students' technological literacy.

Objective : The purpose of this study is to investigate the effect of self swallowing exercise program with neuromuscular electrical stimulation(NMES) on swallowing function. Methods : Subjects who were diagnosed in dysphagia were randomly divided into the control group or experimental group. Both group were received NMES during 60 minutes with traditional swallowing therapy during 30 minutes. Additionally the experimental group was received self swallowing exercise during 30 minutes. We invested subject's characteristics through medical chart. We used VDS(Videofluoroscopic Dysphagia Scale) and PAS(Penetration Aspiration Scale) for assessing the swallowing function. Results : There were not significantly different in both group's pre swallowing function. The control group was significantly improved on pyriform sinus residue, aspiration, and VDS total score(p<.05). The experimental group was significantly improved on vallecular residue, pyriform sinus residue, and VDS total score(p<.05). Both group's difference of pre and post swallowing function were not significantly different. Conclusion : Self swallowing exercise and traditional swallowing therapy with NMES and traditional swallowing therapy with NMES are positive effect on swallowing function. The self swallowing exercise is not effective factor.
