The purpose of this study was to analyze the effect of mediating variables on the relationship between job stress and stress response. A survey was conducted to 243 clinical dental hygienists from January 15, 2013 to March 20, 2013 and the data were analyzed using t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical multiple regression analysis. The subjects who worked in poor working environment, had high level of role conflict and overload and aggressive nature showed high stress responsivity (p<0.01). The variable that showed mediation effect on the relationship between job stress and physical discomfort, depression was shown to be personality type (p<0.05). Also, the variable that showed mediation effect on the relationship between job stress and turnover intention was social support (p<0.05). According to the results, personality type and social support were shown to be important parameters when it came to the relationship between job stress and stress response. Therefore, in order to reduce negative outcomes caused by stress, it is suggested to provide an educational opportunity on self-control management while increasing social support from the organizational and structural level. Especially, it is asked to expand the system that provides encouragement and recognition to feel the sense of achievement in the course of their duty execution.

This study is to present basic materials to further selection of details of health care service bill and supply resources by analysing the consciousness of radiological technologist and dental hygienist about health care service bill proposed for prevention and early diagnosis of a disease through the improvement of living habit. Subjects were 359 of dental hygienists and radiological technologists investigated from 2010 July to September for three months. As the result, recognition level on health care service bill or its details was less than 30.0% but the opinion that health care service bill is necessary was 78.0%. In its additional item, radiological technologist hope to be maintained currently, and 82.3% of the dental hygienist hope to be added, their prefered additional item was dental disease. A dominant opinion was that dental hygienist and radiological technologist as a service supply personnel were included, and their intention to participate was 8.1 in average. In conclusion, the health care service bill is indispensable, but more systematic study is required based on collecting various opinions about major contents and service provider. Particularly it is inevitable to include the health human resources such as experienced dental hygienist and radiological technologist who had completed the regular course of health education and are having continuous clinical discipline.

The immunoregulatory cytokine Interleukin 10 (IL-10) protein is produced by various cells during the course of inflammatory disorders. Mainly, it downregulates pro-inflammatory cytokines, antigen presentation, and helper T cell activation. In this study, we show that the ratio of IL-10-producing cells was significantly increased in lineage negative (i.e., not T, B, or leukocyte cell lineages) cells than in lineage positive cells in lymphoid and peripheral tissues. We further observed that IL-10-producing innate lymphoid cells (ILCs), here called firstly ILC10, were increased in number in oxazolone-induced contact hypersensitivity (CHS) mice. In detail, IL-10-producing lineage negative cells were elevated in the axillary, inguinal lymph node, and ear tissues of CHS mice. Notably, the cells expressed classical ILC marker proteins such as CD45, CD127, and Sca-1. Altogether, our findings suggest for the first time that ILC10s are present in various physiological settings and could be involved in numerous immune responses as regulatory cells.

The purpose of this study was to evaluate the tooth whitening efficacy of 2.9% hydrogen peroxide strip with primer gel of alkaline condition and containing metallic salts as catalyst in-vitro. Hydroxyapatite (HAP) disk was made by compressing and sintering 0.3 g of mixture of HAP powder and polyvinyl alcohol. This HAP disk was stained using modified Stookey's methods. Main bleaching materials were 2.9% hydrogen peroxide strips and the primer gel containing metallic salts as catalyst and pH controller. Stained HAP disks were allocated to each control or experimental groups by color grade. Stained HAP disks were treated for 30 minutes in $37^{\circ}C/80%$ incubator for wetting, then each primer gel according to control or each test group was spread and strips were attached. After 30 minutes for each group strips were detached and HAP disks were washed, dried then color was measured by colorimeter. Efficacy was evaluated by comparing ${\Delta}L$ values of HAP disks at baseline and after treated. Among some kinds of metallic salts for as catalyst, ferric chloride showed best improvement of efficacy and it was statistically significant (p<0.05) compared to control group. Evaluating whitening efficacy according to various pH of primer, efficacy using primer of alkaline condition was increased significantly (p<0.05) compared to control and primers of acidic or neutral conditions. Evaluating whitening efficacy for time course, efficacy of test group for 30 minutes was similar to that of control for 120 minutes. It can be concluded that 2.9% hydrogen peroxide strips using with primer of alkaline condition and containing ferric chloride showed significantly increased whitening efficacy compared to the case of strips only.

Enamel knot (EK)-a signaling center-refers to a transient morphological structure comprising epithelial tissue. EK is believed to regulate tooth development in early organogenesis without its own cellular alterations, including proliferation and differentiation. EKs show a very simple but conserved structure and share functions with teeth of recently evolved vertebrates, suggesting conserved signaling in certain organs, such as functional teeth, through the course of evolution. In this study, we examined the expression patterns of key EK-specific genes including Dusp26, Fat4, Meis2, Sln, and Zpld1 during mice embryogenesis. Expression patterns of these genes may reveal putative differentiation mechanisms underlying tooth morphogenesis.

After Fukushima Nuclear Accident on Mar11, 2011, to grasp the thought of university students in Korea on radiation and medical radiation and seek for the right mass communication on the radiation safety of the people and the proper teaching method on radiation, 790 questionnaires from the universities which had a four-year department of radiological science in 5 provinces(Gyeonggi, Gangwon, Chungcheong, Jeolla, and Gyeongsang-do) all over the country were collected and analyzed. The questionnaire was composed of 36 items, and it was analyzed that one of the important causes that made them feel that radiation was dangerous was 'even if they were exposed to the small quantity of radiation, they could have trouble later.' ($3.28{\pm}1.05$). In the item of the control of radiation, there were the respondents who answered that the government should take action rather than an individual($3.87{\pm}0.89$). In the item of 'Fukushima Nuclear Accident made me think that 'We should not keep nuclear power generation', the result was $2.79{\pm}0.95$. In the item of 'My thought on the medical radiation has negatively changed since Fukushima Nuclear Accident', the students who hadn't taken the course related with radiation showed a negative thought on the medical radiation, such as, there was $2.64{\pm}1.02$ as a whole, $2.31{\pm}1.00$ in department of radiological science, $2.94{\pm}0.95$ in department of dental hygiene, and $3.13{\pm}0.82$ in other departments. And also, those who thought that the education of radiation was necessary were 82.28%, and T.V or Internet was thought as the most effective teaching method.

Purpose .This study aims to assess the influence factors on the level of satisfaction with hospital training and to provide basic data for more efficient hospital practice of students' public health administration . Methods . We have conducted a survey on students satisfaction with their hands on practice against 200 students in Busan, Kyeongnam and Kyungbook area, who have completed their practice in public health administration. We have identified the general characteristics of the target respondents, the current training status of the department for the hospital practice and training venue; also analyzed the characteristics composed of the apprentice student's attitude before the practice, satisfaction with the department training program and hospital for practice, as well as their practice at hospital. The general characteristics of the target respondents and clinic practice status at the hospital were measured in percentage and frequency analysis; the average and standard deviations of hospital size were also measured; and the correlations between satisfaction with the department, attitude towards the practice and satisfaction with the hospital were analyzed. Results . Most public health administration students experienced their practice at the hospital after the first semester on the $2^{nd}$year and they have received the foundation training for the practice. The survey allowed multiple responses and the results are as follows: medical terminology 49.5%, medical coordinator 36.7%, Hospital administration 26.5%, Health insurance 17.3%, and medical recording and practice 13.8% respectively. In terms of each individual student's attitude towards the practice at the hospital, the respondents answered as follows: I have completed the obligatory subjects for the practice before the practice 89.5%; I have been fully informed on the hospital for my practice. 74.5%; I responsibly practiced and worked with professionalism and sense of belonging to the hospital as a member of staff 90%; I have actively learned and adopted 95%; My knowledge and skills from the practice was relevant to the theory and practice from my course 83.5%. The findings of satisfaction by size of hospital were in order of a small clinic($3.24{\pm}0.63$), medium sized clinic($3.27{\pm}0.65$), hospital ($3.20{\pm}0.61$), and large sized comprehensive hospital ($2.93{\pm}0.74$). Consequently the satisfaction rate shows no significant difference by size of hospital. In relations between practice attitude and satisfaction with subject, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.04), the matter of a sense of belonging and responsibility at hospital during practice(p=0.33). the matter of active adaptation attitude during practice (p=0.42), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. In relations between practice attitude and satisfaction with the hospital for practice, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.01), the matter of a sense of belonging and responsibility at hospital during practice(p=0.04), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. Conclusion . The most essential subject for the practice in public health administration is medical terminology and there is no significance in satisfaction with the practice by size of hospital. Students were content with the hospital where they can experience as much as possible. Students content with their major show positive attitude towards the practice and so do those content with the hospital. Those with the positive attitude towards the practice show the high correlation of satisfaction with both the major and hospital. As a result, the satisfaction with the major is the significant attribute to the practice in the hospital.

Secretory leukocyte protease inhibitor (SLPI) involves tissue protection against the destructive action of neutrophil elastase at the site of inflammation. Several studies on new functions of SLPI have demonstrated that SLPI may play a primary role in innate immunity than protease inhibitor, To identify the function of SLPI by lipopolysaccharide (LPS) stimulation in the embryonic fibroblast (NIH3T3) cells. we studied the expression of SLPI compared to other growth factors involving the LPS treatment. To address this, we performed the reverse transcriptase polymerase chain reaction (RT-PCR) and Western blots for the detection of mRNA and protein expression of the SLPI and some growth factors such as VEGF. bFGF, and PDGF-BB after LPS stimulation. NIH3T3 cells were exposed 100 ng/mL Escherichia coli LPS for 30min, 60min, 90min, 24h, and 48h, respectively. The result of RT-PCR showed that SLPI and VEGF mRNA was expressed strongly in NIH3T3 without related to LPS stimulation. mRNA of bFGF was weakly expressed such as the expression of the control. PDGF mRNA expression gradually increased follows at time course. However, SLPI protein level was increased in lysates and culture medium by LPS stimulation. Phase contrast microscopic and scanning electron microscopic observation showed that the increased cell number and cytoplasmic enlargement of the NIH3T3 cells. Therefore, it suggests that the LPS upregulates SLPI expression in NIH3T3 cells. Moreover, secreted SLPI may stimulate cell proliferation and migration.
