Objectives: This study involved a non-equivalent control group, pre-test/post-test measurement experiment to evaluate the efficacy of distributing plaque disclosing agents to healthy adults living in South Korea and promoting its self-application. Methods: O'Leary index, PHP index, oral health behavior intention, and oral care satisfaction were used as research tools. A notice was posted on the bulletin board from September 12 to October 15, 2016, to recruit adults aged 20-50 years. Data were analyzed using SPSS Version 22.0, and frequency analysis, Pearson's chi-squared, one-way analysis of variance (ANOVA), Kruskal-Wallis, and repeated measures ANOVA were performed. Results: The O'Leary index was significantly reduced in the group (p<0.01), and time (p<0.01) after education and width of the decrease had the highest score in the group that received education on plaque disclosing only. They were followed by the group that received education on plaque disclosing and the rolling method, the group that received education on the rolling method alone, and the control group. The PHP index significantly decreased in the group(p<0.01) and time (p<0.01), and the group time (p=0.039) after education, and width of the decrease had the highest score in the group that received education on plaque disclosing and rolling method. They were followed by the group that received education on plaque disclosing alone, the group that received education on the rolling method alone, and the control group. Conclusions: Based on the aforementioned findings, the direct use of plaque disclosing had a marked effect on self-oral care. These results suggest that the self-application of plaque disclosing could be an effective self-care method for improving the oral environment.

Since the curriculum of the department of library and information science for nurturing librarians and teacher-librarians is not standardized and the education scope and content of subjects for each exam to recruit librarians and teacher-librarians is also not standardized, the objectivity and credibility required for national exam are not guaranteed. This study is for developing a standard curriculum as one of the solutions regarding the foregoing problem. To achieve the goal of this study, first of all, the requirements for librarians and teacher-librarians and a national exam related to Teacher Certification Examination, regulation, and implementation rules were reviewed. Secondly, the justification of the suggested subjects through analyzing prior studies for developing a curriculum for library and information science was reviewed. Thirdly, the subjects resulted from the two foregoing methods were confirmed as a standard curriculum for library and information science through a focus group discussion among practicing librarians.

Health Information Exchange (HIE) is expected to improve the quality and efficiency of care by allowing providers online access to healthcare information generated by other providers at the point of care. However, the adoption of the technology in Korea has been slow since its pilot program in 2007~2010 at Seoul National University Bundang Hospital. The objective of this study was to survey stakeholders on the incentive program for the facilitation of HIE adoption. We surveyed 39 experts representing 6 categories of stakeholders-provider, insurer, government, information service firms, customers, and medical informatics experts for the interviews. Interview questions included program objectives, program participation requirements, incentive payment method, and administrative burden for program participation. Experts indicated that the quality of care was the most important value the program should aim to achieve through the HIE adoption. They suggested that the requirements and administrative burden for participation should be kept at minimum to recruit a large number of providers to the program, which is an indicator of program success. Experts were divided on the payment method whether the incentive should be paid as a part of the fee payment scheme operated by the National Health Insurance (NHI) or should be a payment made independent of the NHI. The source of the divide was conflict of interest among stakeholders as to who pays for the program, and the insurer and consumer groups were against the NHI taking the financial burden. It appeared to be the most significant factor for the successful program launching to resolve the gap in perceptions about benefits of the technology among stakeholders and to win the willingness to pay for the program.

Purpose: This study aimed to examine the effect of spouses participating in health coaching on stage of the change, health behaviors, and physiological indicators among male office workers with cardiocerebrovascular disease (CVD) risk factors and compare the findings with trainers who provided health coaching only to workers. Methods: A quasi-experimental pretest-posttest design was used. Convenience sampling was used to recruit participants from a manufacturing research and development company in the city of Gyeonggi province. The health coaching program for the experimental group (n=26) included individual counseling sessions according to workers' stage of change, and provision of customized health information materials on CVD prevention to workers and their spouses for 12 weeks through mobile phone and email. Results: After 12 weeks of intervention, the total score for health behavior, and scores on the sub-areas of exercise and health checkups significantly improved in the experimental group, but there were no significant differences in the scores of stage of the change and physical indicators. The results of a paired t-test showed a significant decrease in the body mass index, abdominal circumference, systolic blood pressure, diastolic blood pressure, total cholesterol and triglyceride values, and a significant increase in the high-density lipoprotein cholesterol value in the experimental group after the intervention. Conclusion: To improve the health of male workers with CVD risk factors in the workplace, sharing health information with their spouses has proven to be more effective than health coaching for only workers. Therefore, it is important to develop strategies to encourage spousal participation when planning workplace health education for changing health-related behaviors.

In order to estimate the ecological parameters of the population, short-necked clams, Ruditapes philippinarum, were collected from Jindu coast at Hansan Island, from April to December in 2005. The growth of the clam was estimated by von Bertalanffy growth model and each parameters were obtained from a nonlinear regression as $L_{\infty}\;=\;48.8\;mm$, k = 0.28 and $t_0\;=\;-0.88\;(R^2\;=\;0.994)$. Instantaneous coefficient of total mortality (Z) and fishing mortality (F) was calculated to be 0.8614/yr. and 0.6122/yr, respectively. The age at the first capture was estimated to be 2.88 year. Using the present parameter for clam fishing, the yield-per recruit (Y/R) was estimated to be 3.44g. Although the maximum Y/R was obtained under the parameters ($t_c\;=\;3.48\;yr$. and F = 0.9295/yr), it is favorable to maintain the current fishing effort considering the annual fluctuation of the parameters.

Even though both N-methyl-4-phenyl-1,2,5,6-tetrahydropyridine (MPTP) and 6-hydroxydopamine have been widely used to establish the experimental model for dopaminergic neuronal ce ll death. mechanisms underlying this phenomenon have not been firmly explored. To investigate how these dopaminergic neurotoxins induce neuronal cell death, murine dopaminergic neuronal cell line, MN9D cells were treated with various concentration of either 6-hydroxydopamine or active form of MPTP, N methyl-4-phenylpyridinium (MPP$^+$). Treatment of cells with 5-100 uM 6-hydroxydopamine resulted in apoptotic cell death whereas cell death induced by 5~50 uM MPP$^+$ was not demonstrated typical apoptotic characteristics such as cell shrinkage, apoptotic body and nuclear condensation. Cell death induced by 6-hydroxydopamine was partially blocked in the presence of antioxidants including soluble form of vitamin E or desferrioxamine suggesting that generation of oxidative stress may be associated with 6-hydroxydopamine-induced cell death in MN9D cells. In contrast, MPP$^+$-induced cell death was not blocked by treatment with any of antioxidants tested. As previously demonstrated that MPP$^+$ caused metabolic alterations such as glucose metabolism, removal of glucose from the medium partially inhibited MPP$^+$-induced cell death suggesting excessive cycles of glycolysis may be associated with MPP$^+$-induced cell death. Taken together, these studies demonstrate that two types of dopaminergic neurotoxins recruit distinct neuronal cell death pathways.

The eventual goal of tumor immunotherapy is to develop a vaccine inducing a specific anti-tumor immunity. Cytokine gene therapy is an effective way at least in animal models, but limited efficacy and various side effects obstruct clinical applications. In this study, we developed a tumor vaccine expressing a membrane-bound form of IL-2(mbIL-2) and SDF-1 in B16F10 melanoma cells. The tumor clones expressing mbIL-2 showed reduced tumorigenicity, and additional expression of SDF-1 to mbIL-2 expressing tumor cells caused more severe reduction in tumorigenicity. However, expression of the SDF-1 alone did not affect on the tumorigenicity, probably because of limited production of SDF-1 in the SDF-1 transfected clones. When the mice once rejected mbIL-2/SDF-1 expressing tumor clone were re-challenged with wild type B16F10 tumor cells, all of the mice survived. This result suggests that mbIL-2/SDF-1 tumor clone is effective in inducing systemic anti-tumor immunity against wild type B16 melanoma. Furthermore, culture supernatant of tumor clones expressing SDF-1 induced lymphocyte migration in vitro. These results, all together, suggest that expression of mbIL-2 and SDF-1 in tumor cells enhances anti-tumor immune responses through different roles; the secreted SDF-1 may function as a chemoattractant to recruit immune cells to tumor vaccine injection site, and the mbIL-2 on tumor cells may provide costimulatory signal for CTL activation in physical contacts.

Police organization tries to recruit competent and young persons, but its concern for retiring persons is extremely little and it expels those who are not prepared to live in outside society. The studies on the management and support the retiring police officers who dedicated their lives to our society are very rare. The object of this study is to study the needs for reemployment in police officers and to develop retirement systems and vocational abilities. Finally, I suggest the establishment of the unit that fully takes charge of retirement management, the method of setting up the learning organization for self-development, the effective ways to get various licenses, the offer of informations on fields of reemployment, the development and management of preparing and support programs for retirement persons.

Purpose: This study aims to investigate and explain the influence of personal characteristics on female immigrants' perception and attitude towards the Korean food culture. Methods: Exploratory research was performed by conducting a self-administered survey. A purposive sampling method was used to recruit 289 participants to determine their level of information awareness, perception and familiarity with Korean food culture. Results: Female immigrants' mean FNS score was 3.70. FNS score decreased in women from Northeast Asia, women who received higher education, and in urban women. The level of information awareness of Korean Food culture was 3.47, which was above average. Women from Southeast Asia had a higher level of awareness about cooking methods and table setting. Females living in the countryside and those who had lived for more than 7 years in Korea had higher levels of information awareness than other groups. Women from Southeast Asia perceived that Korean food is spicy; on the other hand, women from Northeast Asia discerned that Korean food is pungent and is prepared scientifically. The neophilic group more positively recognized Korean foods based on taste and nutritional value than did the neophobic group. Subjects living in the countryside were more likely to evaluate nutritional value, scientific aspects and artistry higher. The research also found that the neophilic group and immigrants who had lived for more than 7 years in Korea were significantly correlated with the familiarity with Korean food culture. Conclusion: The findings provide an initial step towards developing a customized education program for female marriage immigrants to adapt and to become familiar with Korean food culture with a comprehensive understanding of personal traits for accepting a new food culture.
