Staphyylococci are responsible for over 80 per cents of the suppurative diseases encountered in medical practice. They cause most suppurative infections of the skin but may also invade and produce severe infections in any other parts of the body. In order to know the carrier rate of staphylococci between the parahospital workers and in the hospital workers, the author undertook isolation of S aureus from nasal cavity on 68 cases of freshmen, 31 cases of sophomores, and 37 cases of juniors in Busan National University, and 30 cases of nursing students, 30 cases of nurses, 30 cases of nurses in charge of operating room and 30 cases of doctors in Busan National University Hospital. The tested total cases were 256 cases which were 136 Cases in parahospital workers and which were 120 cases in hospital workers. The biochemical characters of S aureus strains isolated were studied on coagulase test, mannitol test, hemolysis test and sensitivity test to antimicrobial agents. The results obtained were as follows: 1. S aureus were isolated 49 cases(29.7%) from nasal cavity parahospital workers and were isolated 67 cases(55.8%) from nasal cavity on hospital workers. 2. Among 40 strains of S aureus isolated from parahospital worker's nasal cavity coagulase positive were 29 cases(72.1%), and coagulase negative were 11 cases(27.5%). And mannitol positive were 29 cases(72.5%), and mannitol negative were 11 cases(27.5%). 3. Among 67 strains of S aureus isolated from hospital worker's nasal cavity coagulase positive were 59 cases(88.1%), and coagulase negative were 8 cases(11.9%). And mannitol positive were 49 cases(73.1%), and mannitol negative were 18 cases(26.9%). 4. The hemolysis test of each erythocytes on coagulase and mannitol positive S aureus isolated were sensitive to rabbit(40 cases: 81.6%), guinea pig(26 cases: 53.6%), sheep(13 case: 26.5%), and were not sensitive to chicken and human erythrocytes, respectively. 5. The hemolysis test of each erythocytes on 10 strains of coagulase and mannitol negative S aureus isolated were not sensitive to all of, erythrocytes. 6. The sensitivity test to the various chemotherapeutic agents was almost sensitive to the strains isolated from parahospital workers, but was almost resistant to the strains isolated from hospital workers.

The student's attitude toward science is generally influenced by their teachers. Therefore, teachers' positive attitudes toward science and science teaching play an important role to change the student's attitude toward science. The purpose of this survey is to investigate the status on attitudes toward science and science teaching among the secondary school science teachers in Korea. The attitudes were surveyed by the questionnaire which was developed by Sung-Jae Pak. The instrument is designed to use Likert type scale and is composed of two kinds of scale: one is the attitudes toward science scale (the AT scale) and the other is the attitudes toward science teaching scale (the AT Kale), which contains 24 questions respectively. Each of them has 6 sub-level areas. The six areas of attitude toward science are as follow: The goals and values, process and method of science, knowledge and the view of nature, social and cultural aspects, scientist and a career in science, the preferences and willingness. The six areas of attitude toward science teaching are as follow: The goals and values, process and method of science teaching, the content and structure, social and cultural aspects, science educator and a career in science teaching, satisfaction and willingness. From 152 teachers' responses, the tendency of total as well as each area and the contrast of their backgrounds at the level of 5% significance were analyzed by SPSS computer program. Some results and conclusion of the study are as follow: 1. The overall attitude of the measured secondary school science teachers shows a positive trend tendency. Also total positive attitude toward science teaching are slightly higher than that of science, which support the fact that the teachers are not scientists but they are directly involved in teaching of science. 2. The attitudes toward science are moderately correlated to the attitudes toward science teaching (r=0.52). 3. The areas of knowledge, nature-view and tile area of social aspects of science show a very negative tendency. Also the two areas are not correlated to some other areal at the level at 5% significance. 4. Female science teachers exhibit just a little more positive attitudes than those of male teachers in science teaching. 5. The science teachers who wanted to have a profession of scholar or educator exhibit a little more positive attitudes than others in science and total attitudes (AS+AT). 6. The more the science teachers have "intellectual delights" the more their attitudes toward science and science teaching are positive. 7. At the level of 5% significance, there are differences which college they graduated from, but there are no differences in multiple comparison at 10% level. 8. The differences in their background dose not appear in such as age; teaching career; academic career; deny the superstition; their onlook for the scientist or educator when they were freshmen; major the basic science; opinions about the U.F.O. and the origin of life. 9. The responses of certain individual statement are quite different from the overall tendencies, which strongly suggest the de1ailed analysis and deeper study. For the continuing study, it is recommendable to revile the measuring tools with the theoretical study for the better validity and reliability, and investigate the status of the attitudes toward science and science teaching among the science teachers with sufficient samples.
The purpose of this study was to examine the health promotion behavior of dental hygiene students in boosting a university student health. The subjects in this study were 687 dental hygiene students in four different colleges in Gyeonggi province. A survey was conducted in September and October 2007, and the collected data were analyzed with SPSS 12.0 program. The findings of the study were as follows: 1. The he freshmen scored lowest in oral health care behavior($3.11{\pm}.57$), and the gap between them and the others was statistically significant (p < .001). 2. In regard to health promotion behavior, the students who found themselves not to be in good shape scored lower in terms of nutritional care($3.63{\pm}.63$), social support($2.43{\pm}.60$), responsibility for their own health($2.40{\pm}.68$) and esteem for their own lives($2.33{\pm}.51$). There were statistically significant differences between them and the others(p < .001, p < 0.01). 3. As to the relationship of the academic background of parents to health promotion behavior, the students whose fathers stopped at middle school($3.62{\pm}.52$) lagged behind most in terms of nutritional (p < .001), and those whose mothers stopped at middle school($2.52{\pm}.52$) were given the smallest social support. The gap between these groups and the others were statistically significant(p < .05). 4. The self-boarding students($3.66{\pm}.57$) fall behind most in the aspect of nutritional care, and there was a statistically significant gap between them and the others(p < .001). 5. The students whose monthly mean household income was one million won or less($2.42{\pm}.62$) valued their own lives least, and the gap between them and the others was statistically significant(p < .05). 6. As for correlation among the variables, stronger social support led to better reverence for life, and better esteem for life was concurrent with better stress management. There was a statistically significant relationship between those variables(p < .01).

The purpose of this study was to develop and evaluate a teaching learning process plan for the practice of caring and sharing to improve character of highschool students through Home Economics subject. The teaching learning process plan consisting of 13-session lessons has been developed and implemented according to the ADDIE model for the unit of 'Happy Family Life and Culture led by Family'. The unit was divided into two themes: Theme I caring through sharing and Theme II caring through practice. Six practice elements of caring and sharing such as communication, gratitude, courage, love, empathy, and environment drawn from Theme I are applied to Theme II. Various activities and teaching materials as well as questionnaire were developed. The plan was applied to 8 classes, 287 freshmen of S highschool in Jeonju-si from March to May, 2014. Three factors were drawn from 35 character-related items: self-perception, perception of caring and sharing, and practice of caring and sharing. These factors were related to respondents' satisfaction with family relationships and school life. Two factors except self-perception improved through 13 lessons. Students evaluated that the whole caring and sharing practice lessons of Theme I and II gave them the chance to realize a actual practice in everyday life was important even with small efforts such as cooking for special family. Also students commented that the praising workbook was impressive. All 23 items of evaluation gained from over 3.5 to 4.2 on 5-point scale. It can be concluded that the teaching learning process plan for the practice of caring and sharing for the unit of 'Happy Family Life and Culture led by Family' would improve character of highschool students through the Home Economics subject.

This study was performed to investigate the relations between dietary habit and academic achievement, subjective health judgement, and physical status. The subjects consisted of freshmen in university and answered to questionnaires through the Internet. The questionnaire consists of the dietary habit, academic achievement (College Scholastic Ability Test), subjective health judgement, and physical status during their 3$^{rd}$ grade in high school days. Data were collected from 3,612 people. Over 33% of respondents had their breakfast daily. Subjects who had breakfast below twice per week were 37.9%. The major reason of skipping breakfast was lack of time to eat breakfast (62.8%). The subjects who recognized the importance of breakfast were 80.6% (p<0.001). More than half (52.7%) thought that dinner was most tasty. People who ate breakfast regularly had a tendency to recognize their health state were in good health (p<0.01). There was no significant difference of BMI (body mass index) according to the frequency of breakfast per week. The subjects who had their breakfast regularly and well-balanced dietary habit reported higher marks in the College Scholastic Ability Test. In contrast, the subjects who rarely had breakfast showed poor marks of academic achievement and subjective health judgement. According to these results, a good dietary habit is considered to be important to academic achievement and confidence in health. Therefore we suggest the school breakfast program and nutrition education program should be required for teenagers. In addition, the findings from this study would provide the basic information for nutrition education in Korean teenagers..

The purpose of this research is to draw suggestions on the settling of the 2015 revised curriculum and the direction of science curriculum improvement by identifying the current status of science general elective courses for high school sophomores, and examining teachers' perception. To this end, with 12 city and provincial education offices' cooperation, we analyzed the status of science elective subjects that freshmen took in 2018 by school year, school type and region. In addition, in-depth interviews were conducted with nine science teachers of the focus group to discuss ways to improve curriculum operation and implementation of science general elective courses, and ways to raise the selection rate. The number of science general elective courses for high school students in 12 municipal and provincial education offices was confirmed to be 163,710 for Physics I, 216,754 for Chemistry I, 290,736 for Bioscience I, and 200,861 for Earth Science I. By school type, autonomous high schools have the highest completion rate, while specialized schools and vocational schools have very low rates. Units completed per semester for general elective courses were mostly three units (61.5%) and two units (28.7%). High school science teachers suggested reconstruction of three-unit elective courses that can be completed in one semester, content development focused on competences rather than knowledge, and the need for a teacher community to improve teachers' teaching competences. Based on the results of the research, ways to operate high school science elective curriculum in preparation for the high school credit system were suggested.
The purpose of this study was to investigate the differences in health belief related to vaccination among dental hygiene students, identify the factors affecting hepatitis B vaccination, and provide basic data for health education concerning hepatitis B prevention. Hepatitis B vaccination was positively correlated (r=0.179, p=0.003) with seriousness of believing that hepatitis B would affect psychological, physical, and social activities and negative correlation (r=-0.183, p=0.002) was also found between perceived barriers related to hepatitis B. As for the factors affecting hepatitis B vaccination, juniors were 0.39 times (95% confidence interval [CI]=0.21, 0.71) more likely to have it affected than seniors and those who were more serious, and who had greater barriers were more likely to have it affected-1.80 times (95% CI=1.29, 2.52), 0.61 times (95% CI=0.41, 0.90) respectively (p<0.05). It is therefore urgent to develop a program within a curriculum that can begin with freshmen along with specific education with the objective of obliging dental hygiene students to receive hepatitis B vaccination. It is also necessary to provide consecutive sessions of education rather than one-time education and to develop a specific plan for obligatory hepatitis B vaccination through correct and thorough education.

The plan consisting of 3 lessons has been developed and implemented according to the ADDIE model. Various activity materials (7 student's activity sheets, 3 reading texts, 1 homework sheet, 3 sets of ppt, 6 videos, and 3 teacher's reading texts) as well as questionnaire were developed for the 3-session lessons. The plans were implemented by the researcher to 204 freshmen, 8 classes, of C middle school in Seoul during september, 2017. The result, of students' lower level of actual participation in interacting with neighbors comparing to their interests in, supported the need of this study. Students were satisfied with the whole 3-lessons in the aspects such as beneficial usage of the contents in their daily life and in building the sense of community, as well as adequacy of materials and activities. Students also reported that they would highly aware to the importance of interacting with neighbors and to practice the contents learned from the lessons in daily life at community. They had an opportunity to reflect one's own attitude to neighbors and recommended to teach it to other schools, too. It can be concluded that the teaching·learning process plan for 'interacting with neighbors' would raise students' housing values living together and attain the overall objective and achievement standards of 2015 home economics middle school curriculum.
