It is well known that smoking habit is hazardous to health, especially for juvenile. The present study on smoking behavior of high school students in Seoul has two major objectives. The first objective is to find out the smoking behavior of high school students in Seoul. Toward this objective, individual's smoking experience has been examined as ever smoking and never smoking. The second objective is to determine the variables associated with their smoking behavior at the individual, family and school environment levels. For the data collection, the survey was carried out for the four high schools in Seoul from September 15 through October 15, 1982. The major findings are summarized as follows: 1. Smoking behavior of the students 1) Out of 1,278 respondents, 30.2% of them were found to be current smokers and 29.3% of them were former smokers. This implies that around 60% of school students in Seoul have experienced smoking. 2) A significant differences in the current smoking rates between two types of the school students were shown as 19.3% for day-time school and 42% for night-time school. 3) In terms of the current smoking behavior, the students who don't live with parents were higher in smoking rate than those of the living with parents. 2. Attitudes and knowledge about smoking 1) Attitudes of students toward smoking in high school days were shown that around 17% of them agreed with it and around 64% of them disagreed with it. 2) Around 99% of the respondents answered that their smoking is harmful for health. A source of the information about negative effects of smoking on health was 'Radio and TV' (23.9%) as the most influential, 'school teacher' (20.9%), 'Newspaper' (18.2%) and so on. 3. Behavioral analysis for the current smokers 1) The factors affected for motivation in the first smoking were 'curiosity' (59.7%), 'temptation of friend' (19.7%), 'resistance feeling, (7.1%), 'merely interest and pleasure' (6%) respectively. 2) The time of the first smoking was 'third grade of Junior-high school' (31.5%) as highest, 'first grade of Senior-high school' (23.7%) and 'second grade of Junior-high school' (14.7%). 3) An average daily number of cigarettes consuming of current smokers was seven cigarettes. 4. Family and school-mates influences on individual's smoking behavior 1) The data revealed a significant relationship between student's smoking and their parent's smoking behavior. Around 75% of the students whom both parents are smoking have experienced cigarette smoking. It was found that the individual's smoking behavior was influenced by his sibling. Around 65% of the students whom brothers are smoking have experienced cigarette smoking. 2) The 'Smoking-Index' of friendship network or a group explained individual's smoking behavior in the group. The result of dyad analysis of smoking behavior in the friendship network showed that a high score of 'Smoking-Index' tended to be explained an adoption of smoking behavior at the individual level in the group. on the other hand, a low score of 'Smoking-Index' explained non-smoking behavior in the group.

Medical personnek are one of several groups that have been reported to have a high incidence of hepatiris B. It is also thought that the occurrence rate of hepatitis B surface antigen(HBsAg), aserologic marker for hepatitis B virus(HBV), is expected to be high in the dental personnel who are frequently exposed to the blood and saliva of the patients. Although many studies have been done to determine the HBsAg status of virus groups, limited investigations have been performed on dental personnel, especially in this country. The main purpose of this study was to identify HBsAg positivity among dental students, interns, and residents who would be expected to be a high risk group of hepatitis B infection. Screening test for HBsAg of a dental school population was performed by indirect hemagglutination(IHA)in 1982. The results were as follows : 1. Thirty four out of a total 362 persons(9.4%)tested in the study had positive response for HBsAg in their serum samples. 2. Twenty seven out of 320 dental students(8.4%)had positive for HBsAg, and in Senior class 12 out of 82 dental students (14.6%)had positive response that was the highest incidence among dental students group. 3. Seven out of 42 interns and residents(16.7%)had positive for HBsAg, and it was the highest incidence in this dental school population.

The reality of violence involving youth has recently increased and has become a serious social problem. The study was done to identity violence related feetors including types of assault, victim status and a violence preventive plan. The subjects were students in boy's high schools in the Jinju area and data were collected through a questionnaire. The research was done to demonstrate the seriousness of school violence and to determine the origins of the problems present measures to eradicate school violence. 1. The types of assault included slander, violent language to classmates, destroying school property, stealing money by beating and violent conduct, sexual harrassment or sexual violence. About 19% of the high school students had experience as violent assaulters. The reasons for such assault were abuse by the victim, discontent at home & school and for amusement with friends without any reason. 2. With respect to the status of damage by violence most cases took place within the school which is considered to be safe for students. Violence such as slander, abuse, violence language, disregarding or excluding took place the most at school and in case of the assaulter it was a college student or a student in the senior grad. 3. As for measure to prevent violence identified by the students, the need to provide space for youth leisure activity was listed as important along with the need for guidance for the future which took into account suitability related to the student's ability and the need to get rid of education mainly for entrance exams. Endeavors to prevent violence must be persistent in all aspect, so that such inhuman like violence will not appear and the negative elements raised by youth will be solved one by one.

Purpose : This study was performed to identify the knowledge and educational wants for first-aid and its related factors of senior students in elementary schools. Methods : From July 11-25, 2008, this study surveyed 437 elementary school students using a structured questionnaire. Result : Of the study subjects, 47.6% of the subjects had experienced first-aid conditions 25.4% had injuries, 11.0% had indigestion, 10.5% had sprains, 6.2% had acute abdominal pains, 5.9% had brash, and 5.7% had fractures. The experience rates of first-aid conditions were significantly different according to gender, mothers' educational status, means of school attendance and amount of exercise. The experience rate of first-aid education was 71.4%. There was a significant difference with grade, and school reports. They had education about cardiopulmonary resuscitation (52.5%), injury treatment and desmology(48.7%) in a good order. The score of knowledge about first-aid was $13.95{\pm}4.1$ and it was converted on the basis of 100 points, the results were below 50points, and there was a significant difference in grades. Educational wants for first-aid was 64.3%, and as a result of multi-logistic regression analysis of characteristics relating to educational wants, there was a significant difference between gender, grade, mothers' educational status, and amount of exercise. Conclusion : The rate of first-aid experience of elementary school students was high, but as their recognition and knowledge on first-aid was low, the importance of first-aid education and educational wants should be reflected for practical and organized education.

Polyurethane foam was utilized to collect protists from the 2 ponds in Seoul National University and another pond in vicinity of Paldang Dam. The identified protists were 4 species in Cyanophyta, 2 species in Euglenophyta, 19 species in Chrysophyta, 9 species in Chlorophyta, 2 species in Ciliophora, and 3 species in Sarcodian. To test the adoptability of the sampling method for classes in junior and senior high school, frequency of the 25 protists in each observation and in each preparation were calculated. The families which were present at high frequencies were Naviculaceae. Fragilariaceae, Cymbellaceae and Coelastraceae. In an experimental application of the 40 pictures taken from the samples, students in junior classes recognized the protists by their outer morphology, internal structure. color, and colonial types, in decreasing order. Use of the collecting method and the applicability of protists for teaching biology were discussed.

This study attempts to compare the topic "approximate value" in mathematics text-books of the 2nd year of South Korean junior high schools and that of the 3rd year of North Korean high schools. In addition, a survey questionnaire was distributed to junior and senior high school students as well as to mathematics teachers in South Korea. Based on the results of the survey, this study attempts to uncover the issues within the current teaching methods of "approximate value" and proposes the directions in which the teaching of approximate value should go in order to enhance mathematical thinking power and creativity of the students. First, it Is necessary to teach students how an error applies to the real world. To accomplish this end, it may be worthwhile to consider introducing the relative errors with more seriousness. Second, it is more important to teach the way of thinking which is concealed in the background of the calculation methods of approximate values than to simply teach mere calculation methods. Third, it is necessary to teach the calculation of approximate value with more realistic examples. Fourth, It is needed to teach students what the differences are when the terminology of "approximately" and "about" is used in real life and in mathematics.

Through this study, we aimed to capture the nature of a mathematics method course, called "the Curriculum Development and Teaching Methods in Mathematics Education" which is a pedagogy course for teaching for secondary school mathematics taught at a university located in a south eastern part of South Korea. The research participants include three junior students who took the methods course and a local high school math teacher with two professors. The research has three parts. First, we designed a method course to prepare the junior or senior students for a teaching practicum. The individual students gave a mini lecture about a secondary mathematical topic as a course requirement. Second, the three students watched a classroom video-clip of the high school teacher and analyzed his instruction before the actual classroom visits. Furthermore, by "Let's Learn" program for students, the course was associated with a local community through the students and so that they could visit the teacher's classroom three times to observe his math classroom teaching. The students discussed the difference between their own mini lectures and the actual math classroom teaching to develop an understanding of what it entails to teach an actual math class. Third, the first author supervised the students' activities in the program including their report for it to bring out their findings to the class of the method course. We found out this method course provided the students with the experience of various aspects of actual math lesson as well as learning theories about the pedagogy for teaching for secondary school mathematics. We conclude that this course gives a model for the method course in mathematics education for secondary school mathematics.

The purpose of this study was to evaluate the diagnostic performance of the senior dental students for the proximal dental caries on intraoral radiographs and to compare it with the dental hospital residents, the reference group. It was also investigated the diagnostic performance according to the carious lesion depth. Thirty-five intraoral periapical and bitewing radiographs with 213 proximal surfaces included in this study were selected from the dental patients at Chonnam National University Hospital. The observers were 181 senior dental students from 5 dental schools and 40 dentists who were second year resident from 5 dental hospitals. They were asked to evaluate the presence or the absence of the proximal dental caries. The results were as follows: 1. The mean of the hitting rate for the overall observers was 184.51 surfaces and the diagnostic accuracy was 86.62％. 2. The diagnostic performance of the sound proximal tooth surfaces was very high, i.e., 91.5％ true negative rate and 8.5％ false positive rate. 3. The diagnostic performance of the dentist group was higher than the student group(P<0.05). 4. The proximal dental caries perceptibility increased as the lesion depth increased significantly(P<0.001) except no difference between the carious lesion depth III and IV (P>0.001).
