The purpose of this study is to compare the health status of Korean and Chosun-Jok elementary children. To accurately achieve the purpose, a survey was conducted in Yanbian area in China and Kojae in Korea during the period of June 15 to July in 1995. This survey was performed by using two survey methods. The first was the parents' survey method. It asked structured questions about their children. The second method focused on the actual health of the children. It used the collection of children's physical records in school. Guided by the school teachers, each child distributed the questionnaires to their parents. We used stratified-cluster sampling method to determine subjects. 1,083 questionnaires of 1,749 were used to analyze the data (666 questionnaires were incomplete and were not used in the analysis). Each questionnaire matched the data of their physical record. : Body Weight, Body Height, Chest-Circumstance, Eyesight, Dental Health. Using the data, we compared the BMI(Body Mass Index) the Koreans and Chosun-Jok in China. The results of this study were as follows : Comparing the general average physique of contained body height, body weight and chest circumstance of Korean and Chosun-Jok, the general physique of Chosun-Jok is inferior to that of Korean regardless of age and sex. Meanwhile, the average physical constitution of Korean compared the Chosun-Jok (i.e. eyesight and dental hygiene), revealed that the physical constitution of Chosun-Jok is superior to that of Korean without concern of age and sex. Average BMI of Chosun-Jok is lower than that of Koreans. But, it seemed that most of the students in both groups maintain an adequate health level. In the case of children from 10 to 12 years old, females are superior to males through all data contained of the body weight, the chest circumstance, and the body height. It seems that females and males have a different maximum growth age. Most of the parents preferred a good physique as a good health condition for their children. The physique of each child was affected with some variables, including the number of family members, and the educational level of the parents. According to the above results, the students' physique in Korea is superior to that of Chosun-Jok in China. But, Koreans are inferior to Ethnic Koreans in China in the students' physical constitution. In conclusion, we consider Chosun-Jok in China to maintain an adequate health level in their physique and physical constitution.

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.

This double-blind controlled clinical and microbiological study was carried out to determine the effects of mouthwash preparation containing the mixture of herbal extract on developing plaque and gingivitis in the experimental gingivitis model. Following a 2-week normalization period, 34 dental students were distributed randomly into 1 of 3 treatment groups. They rinsed, under supervision, two times daily for 3 weeks with either normal saline(CT), 0.1% chlorhexidine(CH), or the mixture of herbal extract (HT), but refrained from any oral hygiene measures. The Plaque Index(PlI), the Gingival Index(GI), and the amount of Gingival Crevicular Fluid(GCF) were measured at week 0,1,2, and 3 of the experimental period, while the assessment of total wet weight of plaque and the phase contrast microscopic examination of plaque were performed at the end of experimental period(3 weeks). Subjects using mouthrinse preparation containing the mixture of herbal extract demonstrated negligible, if any, changes in the accumulation and microbial composition of plaque compared to those using normal saline, while the reduction of gingival inflammation by this mixture was highly significant and comparable to that of chlorhexidine. The results of this study indicate that the preparation containing the mixture of herbal extract do not provide any antiplaque benefits but is very effective in inhibiting the development of and in reducing existing experimental gingivitis when used as mouthrinse. Further research is needed to determine whether a significant reduction of gingival inflammation without a concomitant decrease in plaque accumulation is of clinical importance.
