Purpose: By analyzing factors related to suicide ideation of Korean middle and high school students, the purpose of this study was to multi-dimensionally understand suicide ideation of Korean middle and high school students and arrange the plans to prevent suicide. Methods: This study used and analyzed the data on ‘The 3rd (Year2007) Korea Youth Health Risk Behavior Web-based Survey (KYHRBWS)' conducted by the Korea Centers for Disease Control and Prevention. In this study, we analyzed 74,698 respondents in total. SPSS 12.0 Program was used to analyze the survey. Descriptive statistics, Chi-Square Test and multivariate logistic regression were also used as research methods. Results: 23.8% of the Korean middle and high school students had suicide ideation during the last one year. Girls had higher possibility of suicide ideation by 1.51 times compared to boys. Students with poor academic achievement had more suicide ideation. In terms of health characteristics, students who perceived themselves as not healthy, and students with short weekday sleeping hours, more drinking experience and more smoking experience had more suicide ideation than others. Furthermore, students who perceived themselves as overweight or obese had more suicide ideation than other students. In terms of mental characteristics, students with high level of stress, low level of happiness and depression had more suicide ideation. Conclusion: As a result of this study, we found out that the factor that had the biggest influence on suicide ideation of Korean middle and high school students was depression. Consequently, active supports and policies to decrease suicide ideation of Korean middle and high school students are necessary. Therefore, active interviews, education for suicide prevention, and periodical screening inspection should be introduced in schools.

Purpose: This study was conducted to examine tuberculosis-related knowledge, attitude and preventive behaviors of middle school students and to investigate socio-demographic and health-related factors. Methods: 198 male and 188 female middle school students in M city were recruited for the survey. Independent sample t-test, One-way ANOVA and $Scheff{\acute{e}}^{\prime}s$ test and Pearson's correlation were performed to examine factors associated with tuberculosis-related knowledge, attitude and preventive behaviors. Results: The percentage of correct answers to questions testing tuberculosis-related knowledge was very low, 33%. The mean scores of attitude and preventive behaviors were 3.02 and 2.90 out of 4 (highest score), respectively. Middle school students who had experiences of health education or tuberculosis-related education showed significantly higher scores than their counterparts in all factors - knowledge, attitude, and preventive behaviors. Parental education, academic achievement, smoking, sleeping time, infectious disease education, and source of tuberculosis information were associated with knowledge, attitude, and preventive behaviors. Knowledge about tuberculosis had a positive correlation with attitude and preventive behaviors. Conclusion: The level of tuberculosis-related knowledge, attitude, and preventive behaviors was very low among middle school students. In addition, school health education was highly related to a higher level of knowledge, attitude, and preventive behaviors regarding tuberculosis. Therefore, to intensify students' preventive behaviors against tuberculosis and other infection diseases, sustainable school health education should be provided for middle school students who are at risk of developing tuberculosis.

Objectives : Among adolescents, the proportion of daily smoking tends to increase with age, and does not return to the previous level. Therefore, we examined the factors associated with smoking frequency in a nationwide sample of Korean adolescents to help prevent the progression of smoking. Methods : Among 127,804 adolescents who participated in the 2016 and 2017 Korean Youth Risk Behavior Web-Based Survey, data from 7,781 adolescents who replied that they currently smoked were analyzed. According to the frequency of cigarette smoking, participants were classified into daily and non-daily smokers. Participants' socio-demographic characteristics, smoking behavior, and psychological problems including perceived stress, depressive mood, and suicidality were assessed. Results : There were 3,627(47.4%) daily smokers and 4,154(52.6%) non-daily smokers. Low parental educational level, and early smoking experience were positively associated with daily smoking. High academic achievement, and high socio-economic status were negatively associated with daily smoking. Daily smoking was positively associated with lower happiness, lower sleep satisfaction, and severe stress during the past 12 months. Factors affecting suicide attempts of smokers were sex, residential type, socioeconomic status, and early smoking experience. Conclusion : The results indicated that socially disadvantaged families, and smoking experience with young age influenced daily smoking among Korean adolescents. Daily smoking was associated with psychological problems including lower happiness, lower sleep satisfaction, and severe stress. Early smoking experience influenced suicidal attempts among Korean adolescent smokers. Early intervention for smoking cessation in this high-risk group may contribute to prevention of these psychiatric complications of smoking.

This study investigated the elementary school students' perception of the "purpose of scientists' experiments" and discovered what roles teachers can take to provide guidance. The study subjects were 193 elementary school students (96 boys and 97 girls) in a school located in Gyeonggi-do. The responses were analyzed through categorization based on their gender, science test score at school, and understanding of the purposes of scientific experiments based on students' choice of science-related future careers. The results of this study were as follows. In relation to the purpose of science experiments, the elementary school students considered intrinsic values of doing experiments more valuable than their extrinsic values. Next, 34.2% of the students answered that scientists do science experiment 'to find a new fact' and 26.9% of the students answered 'to make life convenient.' The results showed that girls responded 'social usefulness' more frequently than boys. Considering the achievement levels, it was found that high level students replied 'to make life convenient' more frequently than middle and low level students on why scientists do science experiments. Students who want to have a science-related career had varied ideas about it.

This study aimed at investigating the level of high school students' entrance exam stress and mental health first and also investigating if the entrance exam stress and mental health are related to gender, grade, character type, parenting style and economic status. This is expected to be used as a fundamental data for the development of health education program on high school students' stress and diagnosis of their mental health. To achieve those goals above, the questionnaire was used and the sample consisted of 600 students from general high schools in a large city, C and in a smaller city, A in Chungnam province through questionnaire and the conclusion, which was based on 582 proper questionnaires from the 600 questionnaires, through variable analysis, correlation analysis and multi-regression, is below. First, according to the information provided by respondents, the result showed the relationship between those background variables and the entrance exam stress and mental health level. As the students are more introverted and the parenting style is more authoritative, the entrance exam stress is higher and the mental health level is higher as the parenting style is more authoritative and the economic status is lower. In gender, the entrance exam stress level was high for male students in regard to parents pressure. For female students, it was due to the insufficient free time. In test performance, the good grade group showed high stress level when they don't have enough free time and the poor grade group showed high stress level when they have test tension and poor test performance. In character style, the introverted group showed high stress level in future uncertainty. In parenting style, the authoritative group showed significantly high level in all four sub-factors and there is no significant relationship with the stress level and economic statue. Female students reported higher mental health level than male students in somatization and depression. In academic achievement, the poor grade group showed high level in obsession, fear-anxiety and psychotism. In character style, the introverted group showed high level in sensitivity towards others and depression. And in parenting style, the authoritative group is higher in 9 sub-factors than the other two groups in the factor, economic status. The lower economic status group showed high mental health problem level in this order; in obsession, sensitivity towards others, depression, paranonia and psychotism. Second, the results revealed that there is a significant difference among the groups after comparing and analyzing the relationship between the mental health level according to the three groups, the first, second and third group divided by the degree of entrance exam stress. And the higher the entrance exam stress is, the higher the mental health problem level is. Verification showed that there was obvious difference among the groups. the entrance exam stress was positively correlated with the mental health level. The lack of free time, future uncertainty, test anxiety/poor test performance and parents pressure, these factors, in that order, were correlated with the mental health level. when the prediction variables which influenced on mental health are analyzed, test-anxiety/poor test performance was found to be related to mental health most. And after the factor, test-anxiety, future uncertainty and the lack of free time were listed(ranked), however results did not show any correlation with parents' pressure.

The purpose of this study is to investigate a meaningful path model among the components of students' positive experiences about science and science learning to understand the interactive relationships among different variables of affective domains. Positive Experiences about Science (PES) means whole experiences that have positive effects on students' affectional achievement related with science learning, which consists of science academic emotion, science-related self-concept, science learning motivation, science-related attitude, and science-related career aspiration. We conducted an online survey with 1,841 students consisting of 4th, 6th, 8th, and 10th graders from 17 provinces and cities using Test for Indicators of Positive Experiences about Science (TIPES). To explore the structural relationships among variables, we selected and analyzed an optimal structural equation model and then conducted multigroup analyses among groups. According to the analysis of the structural equation model, 'positive as well as negative science academic emotion' has effects on science learning motivation, science-related attitude, and science-related career aspiration via science-related self-concept. According to the independent t-test results for TIPES scores by participants' characteristics, there were statistically significant differences in the average scores of five sub-components of PES depending on gender, school-level, school location, and participation in science-related activities. According to the multi-group analysis results, the difference of path coefficients by gender and school-level were statistically significant, whereas the difference of path coefficients by school location and participation were not significant. Discussed in the conclusion are the implications of this research for science education research and ways to help students' affectional achievement related with science learning.

The purpose of this study is to explore the science learning motivation of technical high school students through comparison with general high school students. 596 high school students and 1063 general high school students participated in the study. Three statistical methods were used for data analysis: two-way ANOVA, independent sample t-test, and Pearson correlation analysis. The results showed that the interaction between school type and grade had a significant effect on the difference of students' motivation for science learning. There was a significant difference in learning motivation among general high school students according to academic year, while there was no significant difference between first and second grader of technical high school students. Especially, technical high school students showed low level of science learning motivation compared to the students in general high school. The correlations among five motivational factors of science learning motivation were also significantly lower than that of general high school students. Lastly, the result of correlation analysis between science motivation and academic achievement showed that second year students in technical high school had less correlation coefficients than the first year students. Given these results, it is necessary to develop a educational strategy for enhancing science learning motivation of technical school students. We will discuss the direction of science education for technical high school based on our findings.

The purpose of this research was to find out if the analogical role-playing class activity had an effect on the students' academic achievements on cellular respirations as well as their science learning motivation for those who took part in the cellular respiration. To examine the effects of applying the activity, the research was conducted targeting a high school with humanities and social sciences courses, located in Busan. The target was specified as two classes that had selected a Biology II class, with one class (27 students) set as the test group and the other class (28 students) set as the control group. The conclusion drawn from this research was as follows: First, it seemed that the analogical role-playing activity helped the students to take their own parts in cellular respiration and gave them an opportunity to explain the concepts through direct physical activities, enhancing their academic achievements. Second, it was concluded that as the students found confidence and relevance in scientific knowledge as well as obtained a sense of accomplishment, the analogical role-playing class activity increased their level of satisfaction and their science learning motives. Third, as a result of the interviews on the change of the concept, students expressed some dissatisfaction over the new concept, and thought of the analogical role-playing activity as an intelligible alternative. It appeared that the alternative was plausible and fruitful.

The purpose of this study was to develop an inclusive dental hygiene practice model in an effort to stir up the self-directed learning of learners to boost their problem-solving skills and ability of providing inclusive personal oral health care in a systematic and efficient manner. The subjects in this study were 41 dental hygiene students who were in their second year in C college located in South Jeolla Province as of 2009. An inclusive dental hygiene practice was implemented during a 15-week period of time from August 31 to December 7, 2009, and a self-administered survey was conducted before and after that by using the same questionnaires. Whether there were any differences between before and after the application of the inclusive dental hygiene practice model was checked, and there was improvement in all the learning motivation, self-directed learning capabilities and satisfaction level. Concerning the relationship of academic standing to changes in learning motivation, self-directed learning capabilities and satisfaction level, the inclusive dental hygiene practice model brought more favorable changes to the students in the lower tiers. The inclusive dental hygiene model should be applied to not only practical courses but theoretical ones so that learners could make progress both in theory and practice, and evaluation tools geared toward assessing their academic achievement and practical abilities should be developed.
