Objectives: The purpose of this study was to identify the current status of contraception use and analyze factors affecting contraception use among Korean adolescents. Methods: This cross sectional study used secondary data from the 2013 Adolescent Health Behavior Online Survey (KYRBS), which included a nationally representative sample of middle and high school students. A total of 3,475 adolescents who had experienced sexual intercourse were included in the study. Results: Almost 4.8% of total adolescents experienced sexual intercourse. Only 26.8% of them had sex with contraception. The significant predictors related to contraception use were as follows: sexual intercourse experience after drinking (OR=2.02) and living with mother (OR=3.00) for male middle school student, first intercourse experience (OR=2.04) for female middle school students, and first intercourse experience (OR=1.59) and intercourse experience after drinking (OR=0.56) for male high school students. On the other hand, there were no predictors for female high school students. Conclusions: Development and application of effective strategies according to gender and school level are needed to increase contraception rate of adolescents.

This exploratory study is aimed at exploring the validity of the Science Motivation Questionnaire (SMQ) developed for university students, to measure the science motivation of middle school students and analyze the differences on gender and country factors of SMQ. A total of 371 students participated in this study: 171 middle school students from the USA and 200 secondary students from Korea. All participants were enrolled in the STEM program and activities in Utah, USA (for US students) and at a Korean university institute for gifted and talented students (for Korean students). In this study, exploratory and confirmatory factor analyses and latent mean analysis were used to analyze the gender and country differences. The results indicated that the 25 items of SMQ scale were theoretically meaningful and valid for middle school students. The latent mean difference by gender indicated that male students have higher intrinsic motivation, career motivation, grade motivation, and self-determination than female students. Moreover, a significant difference exists in these factors between the two countries. Further findings reveal that Korean students scored higher than US students in terms of the aforementioned factors. This study will provide significant insights in and contribution to science motivation issues in STEM education and the development of design-based engineering programs.

The purpose of this study was to identify the preferable learning strategies in science learning and to find out the relationship between these strategies and scientific achievement of students in the secondary school. The learning strategies were tested with two categories, self-focused and work-focused learning. The four types of learning strategies in science learning were analyzed, and they were named to organization, monitoring, elaboration and memorization strategies, which were defined by GSSS test. In the self-focused learning, the organization and monitoring strategies were preferred to the elaboration and memorization strategies. Middle school students had a preference for memorization strategy (p=0.000), whereas high school students had a preference for monitoring strategy (p=0.015). In the case of organization strategy, female groups were preferable to male groups (p=0.027). In the second form of learning types, work-focused learning, the memorization strategy was the same preference as organization and monitoring strategies in the secondary school students, especially the male groups of high school students. The preference of elaboration strategy was relative lower compared with that of self-focused learning type. Middle school students had a preference for monitoring strategy (p=0.001), whereas high school students had a preference for elaboration strategy (p=0.001). The difference of each preference between male and female groups was not shown. From the analysis of correlation between learning strategy and scientific achievement, it showed that the monitoring strategy was commonly correlated with scientific achievement. In the self-focused learning, elaboration and organization strategies were correlated with scientific achievement in high school students (p<0.05). In the work-focused learning, memorization strategy was correlated with scientific achievement in middle school students, especially in male groups (p<0.05).

The purpose of this study is to analyze the gender differences of elementary, junior high, and high school students in the artificial intelligence ethics awareness (hereinafter referred to as AIEA). This is a study to investigate whether there is a gender difference in the AIEA, and if so, when the gender difference will occur. This study was conducted with 198 elementary school students (98 female students, 100 male students), 265 middle school students (166 female students, 99 male students), and 114 high school students (58 female students and 56 male students) in I Metropolitan City. The results are as follows: First, a gender difference in the AIEA between all boys and girls was confirmed. Second, the gender difference in the AIEA tended to be solidified as the school age increased from elementary school to middle school and high school. Third, female students at all stages of elementary school, junior high school, and high school are not yet very reliable in artificial intelligence, and there is a greater concern about non-discrimination than boys. It turns out that they have a negative position on permission to enter the territory. Fourth, the interaction effects of school age and gender have been identified in 'stability and reliability,' and in 'permit and limit' categories. Taken together, these results show that an educational strategy that approaches the gender equality perspective of the educational program is necessary so that there will be no gender difference in the AIEA during artificial intelligence education activities.

Purpose: The purpose of this study is to investigate the factors influencing suicidal ideation in middle school students. Methods: Suicidal Ideation Questionnaire (SIQ) results, personal characteristics, child abuse experiences, and stress were obtained from a sample of 657 middle school students from 3 conveniently selected schools in S city. Results: Suicidal ideation of participants was positively correlated with child abuse experience, stress, psychosomatic symptoms, antisocial personality and depressive tendencies, whereas sociability and self-esteem were negatively correlated with suicidal ideation. Significant factors influencing suicidal ideation included an antisocial personality tendency, stress related to the family environment, mental abuse, gender (female), depressive trend, running away from home, sociability, and stress related to academic performance. These factors explained 39.9% of the variance. Conclusion: These results suggest that earlier screening and intervention programs for depression and stress in middle school students will be helpful in reducing suicidal ideation. Further studies are needed in which other strategies that could prevent suicidal ideation in middle school students are examined.

The purpose of this study was to survey the actual condition of the Middle School Students on a Drug. In this study, 500 middle school students in Seoul response to a questionnaire which is composed to analyse two categories, i.e. general facts, the actual condition of drug use (the frequency of drug use, the degree of perception on drugs, the people using a drug surrounding the degree of purchase on drugs). And the students are classified by satisfactory degree on their home backgrounds, satisfactory degree on their school life, and school record. The data is analysed by means of frequency, percentage, chi-square test and Pearson's correlation using the $SPSS-PC^+$ package program. The results of this study were as follow : The frequency of drug use except a alcohol and the degree of perception on a drug among female students are higher than among male. The female students are more permissive on the drug use and they are also tend to think more easily the purchase of a drug. The frequency of drug use and the degree of perception on drugs are higher in the group of the lower satisfactory degree on their home background. Especially, there are many people using drugs surrounding the students in the lower group. The frequency of drug use and the degree of perception on drugs are higher in the group that has the lower satisfactory degree on school life. The students in the group having low school record have more dangerous thought about the use of drugs than the students of high record. The degree of perception on a drug is higher in a higher group, and the students in a higher group also think more easily the purchase of drugs. The percentage of students using drugs are not high, but the high percentage of students are interested in the drugs and they have permissive attitudes on drugs. Thus, the preventive education for drug abuse must be done rapidly.
