  • Entrepreneurship provides working opportunities to not only an entrepreneur himself but also many other people on the way its process. Boosting entrepreneurship, therefore, seems the most effective way for activating one's economy as well as creating jobs. This study examines factors that influence on entrepreneurial intention of Korean and Korean-Chinese's who will eventually be the potential entrepreneurs. This model tests various theoretical research hypotheses relating to individual psychological characteristics, and entrepreneurial motivation and entrepreneurial intention. Valid 247 questionnaires have been collected within about one month of 2013. Statistical processing of the data collected from this survey to take advantage of the statistical package SPSS 18.0 program through a process of data coding in the following ways: by frequency analysis, factor analysis, regression analysis. The result of hypothesis testing are as follows. The result of analysis shows that risk-taking propensity and desire for self-achievement is not a significant factor to entrepreneurial intention in both countries. But entrepreneurial self-efficiency and entrepreneurial motivation positively influence entrepreneurial intention both of the Korean and Korean-Chinese. At the last, the study examines moderate effect, that is, whether social support influences on entrepreneurial intention as a moderate variable. it is confirmed that the social support does play a positive role to entrepreneurial intention. Beside, discussion is made on the implications of the study for academicians and practitioners, the limitations of the study, and some directions for future studies.

  • This is a research for thickness change of denture base according to the shape of sprue & investment position of denture base in flask when injecting polyamid base resin for flexible partial denture as a part of study for Valplast among the flexible partial denture with a nylon base. It has been introduced several kinds of flexible partial denture product with a nylon base, but Valplast is the most widely used product among them. Valplast has been the most generally used material today since developed in 1950s in the United States as a material for flexible partial denture. Valplast is much more aesthetic than general metal-acrylic partial denture due to its translucent pink color and biocompatibility in terms of material characteristic. It keeps its flexibility for a long time after production, imposes a less burden on the teeth used as abutment, and it can be easily insert and remove due to its particular suppleness. Moreover, it is felt like real teeth more than metal-acrylic partial denture when being put in and takes alveolar bone under good protection since it receives occlusal force equally under the denture base. The most outstanding feature of Valplast is flexibility. The extent of its flexibility is determined by width & thickness of denture base. Considering general working procedure of Valplast, it can be seen that the thickness of denture base formed out of wax is increasing by the pressure while injecting resin. This research is to decide and test on the thickness increasing of Valplast by injecting pressure and the hypothesis upon that and is to prepare the basis estimating the increasing extent of thickness of denture base on the basis of the test result. In this test, it is expected occlusal malposition & thickness increasing of denture base by injecting pressure according to 4 kinds of test data which are to select 3 types of sprue method settling the forefront position at which the test material of fixed standard can be invested and to position the test material at the rearmost part keeping the minimum distance to set sprue. For 4 kinds of injecting test by investment position & sprue type, 20 test materials, 5 for each test were produced and a pressure of 1,180Kg was given with automatic injector of air cylinder type. The results are as follows: 1. For the amount of thickness increasing of denture base by investment position, the thickness of front investment is less increasing than the one of rear investment. 2. For the amount of thickness increasing of denture base by sprue type, the thickness of straight decompression sprue type which can absorb the injecting pressure after injecting polyamide base resin is less increasing than the other sprue types.

  • The purpose of this study is to define the relationship between ethical management, organizational culture, and management performance in long-term care institutes for the elderly while identifying the level of ethical management, organizational culture, and management performance of caregivers and the impact and mediation of the relationships between them based on the hypothesis. The results show that caregivers in the Gyeonggi region scored 2.929 out of 5 in ethical management, 3.393 in organizational culture, 2.925 in organizational transparency and 3.185 in management performance. The levels of ethical management, organizational culture and management performance in caregivers are lower than those of welfare workers, social workers, and nursing assistants. This is due to their relatively low level of education, wages and working environment. This study determined that there is a significant relationship between variables in terms of correlation between ethical management, management performance, organization transparency, and organizational culture. Second, the authors adopted hypotheses that ethical management has a statistical effect on organizational transparency, management performance, and organization culture. Third, the authors concluded that organizational culture has a direct impact on organization transparency and there is a significant mediation effect between ethical management, organizational transparency, and management performance. Based on these results, we propose the following: First, ethical leadership at the core of ethical management. Second, awareness in organizational transparency. Third, balanced management performance. Fourth, a flexible organizational culture that can respond to ethical management environment must be established.

  • The purpose of this study was to examine the effect of the possibility of job-related risk, emotional labor, and emotional leadership on the job turnover intention of caregivers working at the long-term care facilities in Korea. For the study, survey data of 434 caregivers at senior nursing homes were collected and analyzed using hierarchical multiple regression method. The results showed that high level of caregivers'perception of both the possibility of management risk and employee risk led to increased turnover intention. On the other hand, perception of the possibility of social-disaster risk did not give significant impact on turnover intention. Although the perception of the possibility of service user risk gave statistically significant effect on the turnover intention, the direction was the opposite to the one set at the research hypothesis. Frequent camouflage behavior("surface acting") of caregivers, which is the kind of emotional labor led to increased turnover intention. However, caregivers'behavior consistent with their inner warm heart("deep acting") did not lead to a statistically significant result. Lastly, the more caregivers perceive their superiors'emotionally supportive leadership, the lower possibility of turnover intention. Based on the above result, the researchers suggested several intervention methods in order to prevent turnover of caregivers and improve service quality of long-term care institutions.

  • The objective of this study is to search for a theoretical and practical solution to the question of what is the most effective and qualitative method of information service for the college and university libraries in Korea. Assuming the maximum service or total service theory in information services, therefore, it appears natural that the subject specialist who is highly knowledgeable in his subject is indispensable in raising the quality of information librarians. The procedure of this research was as follows: There was no college and university library employing any full-time subject spceialist in Korea. This research, however, was proceeded on the assumption that subject specialists are already employed in all of the college and university libraries after the subject specialist system is established. The least qualification of subject specialist is limited, based on the criteria given by the foreign literature, to those who have master's degree in Library Science and bachelor's degree in any other subject area, those who have bacholor's degree in Library Science and master's degree in any other subject area, or those who have both bacholor's and master's degrees in Library Science with minor in any subject field . To prove the research hypothesis that the subject specialist will perform his role more efficiently than the generalist in effectively providing information service based on both accuracy and speed, this research as an obtrusive testing method analyzed the effectiveness by presenting information questions to the generalists and subject specialists who are information librarians in college and university libraries. For this study 20 librarians working at 12 university libraries were tested for performance levels of information services. The result showed $59.75\%$ an absolute performance rate and $75.20\%$ an adjust performance rate. Compared to Thomas Childer's 1970 study in which he used the unobtrusive testing method, these results were $5\%$ higher in the absolute performance rate and $11.36\%$ higher in the adjust performance rate. In comparing the generalist with the subject specialist in efficiency of information service, while the absolute performance rate was $57.08\%$ and the adjust performance rate was $73.08\%$ in the case of the generalist, the absolute rate was $63.75\%$ and the adjust rate was $78.38\%$ in the case of specialist, therefore, the efficiency of the subject specialist was $6.67\%$ higher in the absolute performance rate and $5.30\%$ higher in the adjust performance rate than that of generalist. But the factor of speediness was excluded from the analysis because of the difference between the time the interviewers recorded and the time the interviewee recorded. On the basis of the result of this research, it should be desirable to educate subject specialists and employ them as information librarians and for them to function as efficient subject specialists in order to improve the effectiveness of information services, the nucleus of the raison d'etre of college and university libraries.

  • This study purported to examine the effects of precarious employment and social capital on the changes of self-rated health status among the middle aged and the young-old population in South Korea. The study analyzed 12 year follow-up data generated by the Korean Labor and Income Panel Study(KLIPS 6-17), which included 10532 employed subjects aged 55 to 75. Multi-level growth curve modeling was performed by fixed and random effect models using STATA 13.0 program. Afterwards, Hausman test was performed, which resulted in support of the estimation by fixed effect model. The results showed that a day labor position was significant factor affecting the deteriorated changes of self-rated health status over time. In addition, wage, weekly working hours, and private/relational social capitals were also found to be significant factors affecting the changes of the self-rated health status. The results supported the divergence hypothesis as well as the cumulative advantage theory. Efforts should be made to develop and implement various employment support policies and social service programs to alleviate the health inequality of the employed workers over their middle-aged to young-old period.
