Objectives : The purpose of this study was to analyze the status of oral health in relation to the acknowledgement of oral health trouble and oral health habits. Methods : This study was conducted after IRB was received, on 273 patients who had received health screenings between October-1, 2014 and January-31, 2015 at a general hospital in Busan. Results : Regarding the status of oral health in relation to the acknowledgement of oral health trouble, the rates of dental caries and periodontal disease were higher when the patients knew the reasons for trouble about the oral hygiene. With regard to oral health habits, our results showed that the more frequently the patients ate sugary snacks per day, the probability of experiencing periodontal disease was higher than for the patients who did not eat sugary snacks. Our results also, showed that the occurrence of dental caries is very much dependent upon whether a patient had experienced education on toothbrushing. Conclusions : Patients need to become more aware of their oral health through education. A program that emphasizes the importance of preventive oral health behaviors and the maintenance of correct oral health behavior should be developed.

The purpose of this study is to understand present situation of clinical trials, and evaluate the preparedness of the desiRnated institutions to abide by GCP(Good Clinical Practice) standards during clinical trials. Survey on the status of clinical trials was conducted for the desienated 83 clinical trial hospitals, and response rate was $95.2\%$. The results showed that 39 hospitals have conducted clinical trials to obtain drug manufacturing approval from 1990 to 1994. Most of them were trials on Phase III. Only $46.8\%$ of the institutions had sufficient human resources to perform the clinical trials. Institutions which established IRB(Institutional Review Board) accounted for 41 or $51.9\%$, but those who have a protocol evaluation guideline, or Adverse Drug Reaction(ADR) reporting system were only 12, and 21 Places, respectively. Regarding supervision of the investigational drugs, less than 30 institutions designated pharmacist as a supervisor. In conducting clinical trials, $97.4\%$ of trials had high rates of prior consent of testees, but only part of them-$61.7\%$-gave written consent. The level of conducting GCP is found to be unsatisfactory. Institutions must build the appropriate infrastructure and government must prepare in order to protect testees' rights as well as to ensure validity of the results.

Face transplantation has been reported over the last six years, and it started in 2004 with the announcement of Cleveland Clinic granting the world's first IRB approval to proceed with human face transplantation. Composite tissue allografts (CTAs) in the facial region are considered to be more immunogenic than other solid organ transplants, so these kinds of animal experiments were also considered as challengeable activities to the facial reconstructive surgeons. For the better understanding of CTAs in the oral and maxillofacial fields, we reviewed several recent articles about facial composite transplantation animal model, and summarized some knowledges of composite midface allotransplantation model with sensory and motor reinnervation in this review article.

Purpose: The objective of this study is to analyze systematically the trends of experimental researches in the area of community health nursing. Methods: This is a study based on literature review, which analyzed 137 experimental research papers in the Journal of Korean Academy of Community Health Nursing, from the first issue in 1989 to those in 2012. Results: 1) The proportion of experimental researches in the total published papers was 14.9%. 2) The mainly used research method was quasi-experiment, which was 60.6% of them, and there was no RCT. 3) Convenient sampling was used in 95.6% of the researches. 4) Only 5.1% were reviewed for keeping the ethical standards for the study objects by the IRB. 5 When classified by the Omaha Classification System, psycho-social researches were most frequent, which were followed by physiological, health-related behavioral, and environmental ones in order of frequency. Conclusion: This study found that the proportion of experimental research papers was increasing in the 2000s and ethical standards were required more rigorously. However, it was suggested that the research design be more elaborated and sampling methods be manifested to reduce research bias and errors.

Objectives: The purpose of this study was to investigate factors affecting the drinking behavior in high school students. Methods: There were 620 subjects who were first and second graders of seven high schools in Daegu. This study used Sinhaengwoo (1998)'s drinking behavior scale, Rowlison and Felner (1988)'s stress scale, Kovacs (1981)'s children's depression inventory, Rosenberg (1965)'s self-esteem scale. The data were analyzed by descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression using SPSS/win 18.0 program. This study was approved by the Institutional Review Boards (IRB) of the Keimyung university hospital(No. 12-112). Results: The mean score for drinking behavior in high school students was 23.1points. Factors influencing drinking behavior in high school students were identified as self-esteem(t=-3.67, p<.001), stress(t=6.79, p<.001), school types(t=4.02, p<.001), sex(t=-3.67, p<.001). These factors explained 27% of drinking behavior reported by high school students. Conclusion: The results indicate which factors are majors influencing drinking behavior in high school students. Therefore, self-esteem enhancement could be considered as an effective strategy to reduce the drinking behavior in high school students.

This review was conducted to investigate clinical trial trend, clinical effect, and study methods of forest healing. Literature search was performed using the search engines of eight electronic databases from inception to march 2010 without language limitation. The search terms were "forest healing", "forest experience", "forest therapy", "forest treatment", "clinical trial", and "clinical study". Inclusion criteria were randomized controlled trials (RCTs) among all kinds of study searched about forest healing. Selection literature and data extraction was performed by authors(SH Sun and SG Lee) independently. Total three studies were selected finally. The methodological quality in all study was low because of poor reporting. Study indications were metal health, depression, self-esteem, and stress. The scale of studies was very small, which was the level of pilot study. There were no description for obtaining informed consent and being reviewed by Institutional Review Board (IRB), and could be any problems for statistical method in any studies. It is difficult to accept the fact that each studies had the significant effect for study indications in the results of studies. It is concluded that the evidence that health healing have a significant effect is insufficient. Further systematic and methodological study and well-designed clinical trial will be needed.
