The purpose of this study was to investigate research ethics awareness for health and medical science researchers. The variables for the study included intrinsic motivation, knowledge sharing for research ethics awareness. The data were collected from 254 employees of the research ethics awareness who gave their informed consent and completed a self-reported questionnaire in May, 2017. A path analysis model was established and used to assess parameters such as research ethics concern, intrinsic motivation, knowledge sharing for research ethics awareness. The fitness of the hypothetical model was adequate(=49.585, GFI=0.954, NFI=0.895, CFI=0.915, IFI=0.916, RMR=0.021). Research ethics interest was found to have a positive influence on intrinsic motivation, knowledge sharing, and research ethics consciousness. Intrinsic motivation as a parameter was positively (+) influence on knowledge sharing. SMC (Squared Multiple Correlations) is a multiple correlation coefficient which is explained by exogenous variables, and explanatory power of intrinsic motivation, knowledge sharing, and research ethics are 15.2%, 24.0% and 18.0%, respectively. Research ethics interest in the research ethics of health and medical science researchers was significant as direct and indirect effects. In order for the correct ethical consciousness to be established, it is necessary to raise the interest in research ethics, and to establish an intervention strategy to strengthen the intrinsic motivation of the research as well as sharing knowledge among researchers.
Objectives: The purpose of the study is to investigate the effect of chewing gum containing Prunus mume extract(PME) on the change of saliva ingredients. On the basis of the biological background of molecules and diagnostic indices in the use of saliva, the mastication effect of chewing gum containing PME was demonstrated in terms of secretory IgA concentration and total protein concentration in stimulated saliva. Methods: This study is an experimental research on the use of a research design before and after applying a randomized control group. Participants were distributed randomly to the experimental group and the control group, respectively. The experiment group was instructed to masticate the chewing gum containing PME for 10 minutes for one month after each meal within 30 minutes. Salivary secretion was collected by the participants between 8 and 10 a.m in the morning in the research office. For the measurement of secretory IgA and total protein concentrations in the saliva, indirect enzyme-linked immunosorbent assay(ELISA) was used. Results: The salivation stimulation rate was significantly increased after four weeks of masticating chewing gum containing PME after each meal(p<0.001). Mastication of chewing gum containing PME for four weeks decreased the concentration of secretory IgA much more significantly than that after mastication for one week(p=0.003). The concentration of total protein in the saliva was decreased after four weeks in the experimental and control groups. Conclusions: Mastication of chewing gum containing PME stimulated salivary secretion and led to oral disease prevention in patients with xerostomia. Furthermore, it seems to be urgent to seek measures that can be utilized in intervention for patients with xerostomia.
The purpose of this study was attempted to analyze the factors influencing satisfaction on clinical practice and the Relationship between Achievement motivation and Satisfaction on clinical practice. The subjects were 452 dental hygiene students of junior college in Korea. The instruments used the achievement motivation scale developed by Yong-Hun Park and the satisfaction on clinical practice scale by the researcher based on the Sook-Ja Lee. The data were collected from February 20 to March 11, 2000, by the questionnaire method. The data were analyzed by Frequence, Mean, t-test, ANOVA, Duncan's multiple range test, Pearson's correlation coefficient, Multiple regression for associations and Cronbach's Alpha for reliability using SPSS. The result of the study were as follows: 1. The average achievemet motivfation score of subjects was 3.73. 2. The average satisfaction on clinical practice score of subjects was 2.95. 3. In the relationship between the achievement motive and general characteristics, there was significant difference -- the students who are the olders(p=0.018) and studying in the evening time have higher level of achievement motive than the students who are studying in day time(p=0.008). Also the students who have high achievement of professional education(p=0.000) and the students who have high satisfaction of dental hygiene theory showed a higher level of achievement motive(p=0.000). It shows that the people, who try to develop themselves continually have a higher level of achievement motive instead of being content with things as they are. 4. In the relationship between satisfaction on clinical practice and general characteristics, there was significant difference -- the group which has more satisfaction of dental hygiene showed higher satisfaction on clinical practice(p=0.000) and the group which has practiced in university dental hospital and hospital than dental clinic showed higher it(p=0.026). 5. There was the positive correlation at a significant level between achievement motivation and satisfaction on clinical practice(r=0.292). AS mentioned above, The level satisfaction on clinical practice of student of Dental hygiene was revealed to be low. For more efficient and desirable practice education, I would like to suggest that managerial program is required actively according to practice curriculum to study comparison with a field of study. The training programs to enhance private achievement motive also should be developed concretely and actively.
본 연구는 B화력 직원들이 대형화재의 위기관리 복구과정에서 인지했던 심리적 소진과 집단주의가 조직몰입에 미치는 영향을 파악하기 위하여 소진, 집단주의, 조직이미지, 외부이미지, 직무만족과 조직몰입 간의 경로모형을 검증 및 구축하였다. 자료수집은 B화력 조직원 286명에게 구조화된 설문지로 자기기입법에 의한 설문조사를 실시하였고, SPSS와 AMOS 프로그램을 이용하여 분석하였다. 가설모형의 전반적인 적합도는 양호하였다(=5.52, p=.05, GFI=.992, CFI=.981, IFI=.982, AGFI=.913, RESEA=.083, SRNR=.032). 본 연구의 가설적 모형에 대한 분석결과, 대상자는 조직몰입에 대하여 소진, 집단주의 및 직무만족이 직접효과와 총효과를 갖는 것으로 나타났다. 또한 조직이미지와 외부이미지는 조직몰입에 대하여 간접효과와 총효과가 유의한 것으로 나타났으며, 모형의 설명력은 72.9%였다. 본 연구결과를 토대로 위기관리에 대처하여 조직몰입을 높이기 위해서는 조직구성원들의 소진 중재 프로그램개발이 필요하며, 집단주의, 조직이미지, 외부이미지 및 직무만족을 높이기 위한 방안 모색이 필요하다.

Methods:Total of 992 researches were published between 2001 to 2015 were reviewed using analysis criteria. Results: 23.7% of the researches were supported financially. The most frequent research topics were oral health (40.9%). 3 to 5 researchers per research (38.5%) was most common and 84.1% of principal researchers were professors. 29 researchers were approved by IRB (2011 to 2015). As for the type of research, 87.1% of quantitative studies adapted survey and 9.5% adapted experiment. Convenient sampling was used in 85.6% of the researches. 32.7% of studies searched information in school.

Conclusions: The findings of this study suggested the recent trends and the direction in dental hygiene research.
To resolve the environmental and economics problems of fossil fuel energy, a hydrogen economy is promoted in many developed countries. Massive production of hydrogen using a nuclear power is a practical way to feed fuel required for the hydrogen economy. The author introduces a very high temperature reactor and its development status. He also reviews recent achievements and directions of research in hydrogen production process, such as sulfur-iodine thermochemical cycle, sulfur hybrid cycle, and high temperature electrolysis. 화석연료 사용으로 야기된 환경문제, 경제문제를 해결하기 위한 방안으로 수소경제가 추진되고 있다. 원자력을 이용한 대량수소생산은 수소경제를 뒷받침하기 위한 현실적인 방안이다. 본 논문에서는 원자력수소 생산에 사용할 초고온가스로의 특징과 개발현황, 초고온가스로로부터 발생하는 고온의 열을 이용한 수소생산방법 중 유력시 되는 기술로서 요오드-황 열화학법, 황산하이브리드법, 고온전기분해법의 기술개발 현황과 방향을 소개한다.
