Students are exposed to many visual representations in various visual cultures. Infographics combining visual representations and writing can effectively convey information. Also it can be efficient ways for teachers to focus on important contents. Students can use infographics as a method directly to organize information. Therefore, the infographics that students use both writings and images directly and visually will be more effective on elementary school science classes than the workbook. Classes are guided with the same scientific inquiry and experiment written on the science textbook. The experimental group students organized scientific inquiry by infographics, while the comparison group students still used the workbook. First, the types of infographics are determined by what students want to explain. Based on learning objectives, students used the right type of infographics to effectively convey their focus on information. Second, the infographics organizing activities used in the classes had a significant effect on students' academic achievement. Also, the infographics organizing classes are positively associated to science-related attitudes, including such+ as 'Leisure Interest in Science', 'Adoption of Scientific Attitudes', and 'Attitude to Scientific Inquiry'. Third, visual tendency and classroom treatments had no interactions, but the experimental group had a positive impact regardless of student's characteristics. Fourth, experimental group showed positive attitudes toward to students' perception of infographics. Since some of students had difficulties organizing information in infographics, further research is required to enable students to reduce their burden in application of infographics.

By using the concept of 'Resonance' in benzene which stems from a unit dealing with the carbocyclic compounds which is in a text 'Chemistry I', I developed teaching methods based on the history of science. This study was executed to analyze the effect by applying these methods. Seventy 3rd grade male students, who are attending a high school located in the Pohang area were used in this study. I investigated the level of the relative difficulty and the degree of scholastic achievement from each treatment group and controlled group using the concept of Resonance from the preceeding study. In this study, these 70 students divided into two classes- a traditional lecture group consisting of male 35 student, and a group using the history of chemistry consisting of the remaining 35 student and after a specified period, their scholastic achievement was analyzed. As a result of this study, the treatment group scored much higher (50.143) than the controlled group(25.429) in average score and showed significant difference between two groups. Through this study was based on the history of chemistry, after scientists let them realize the process of improving science attitude, and think like scientists, giving conceptual class can get much more efficiency and durability for learning.

This study aims to determine the effects of mental health on obesity among Korean adolescents. The data in this study were obtained from the 2013 Korean Youth Health Risk Behavior Web-based Survey conducted in 70,354 adolescents aged twelve to eighteen (35,575 males and 34,779 females) from June 1 to 30, 2013. The variables included age, the economic status of household, academic achievement, health status, perceived happiness, perceived stress, satisfaction of sleeping, perceived depression, and suicidal ideation and the data were processed using t-test, chi square test, and logistic regression analysis. The general characteristics affecting obesity for both Korean male and female adolescents included age (p<0.001), the economic status of households (p<0.001), academic achievement (p<0.001), and health status (p<0.001); the variable of mental health affecting obesity was suicidal ideation among females (p<0.05). It is expected that female adolescents' experience of suicidal ideation can be used as information to predict the likelihood of obesity in managing an obesity program for adolescents and it is necessary to provide obesity education suitable for age and to include obesity guidance in consideration of gender and the economic status.

University dormitories play an important role in both the campus experience and academic achievement, as well as providing the students with their basic necessities. Further, there is a high demand to increase the capacity in order to raise the retention rate and to invite more foreign students. Students' social interaction and sense of community (SOC) also play an important role in reducing the stress associated with studying and home sickness and, consequently,the campus is a place that provides positive opportunities for their personal growth and adaptation into their peer group social culture. The purpose of this study is to investigate the effects of the physical environment of the dormitory facilities on the students' sense of community and social interaction in across-cultural background.The ${\chi}^2$ analysis indicated that individual characteristics exist regarding SOC, however, there were no statistically significant differences between the two cultural groups. The factors of SOC and physical environment were higher in the Korean student group than in the U.S. group. The regression analysis indicated that the U.S. students considered a physically comfortable environment as the primary issue for social interaction, while the Korean group placed more emphasis on a family-oriented home environment. The linear analysis confirmed that satisfaction with the physical environment influenced the social interaction and SOC level. Finally, this study suggests that creating a homely environment is more important than the functioning of the institution in university dormitory planning.

The purpose of the study were to analyze the patterns of adolescent suicide attempts, and to explore the effects of personal psychology (subjective depression, subjective stress), health status (BMI, subjective health perception), and subjective academic performance on the types of youth suicide attempts. For this research, data of 'The 15th Korea Youth Risk Behavior Survey' were analyzed employing a hierarchical logistic regression analysis. The findings are as follows. First, out of 1,731 youth suicide attempts 156 (9%) were impulsive and 1,575 (91%) were planned. Girls(67.3%) attempted suicide more than boys (32.5%), and middle school students (62%) attempted suicide more than high school students (38%). Second, the variables that significantly affect suicide attempt types were subjective depression, subjective stress, and subjective health perception, after controlling for gender, grade level, school type, and SES. The rate of planned suicide attempts was higher among those who experienced depression than among those who did not. In the case of subjective stress, adolescents who felt stressed were likely to commit planned suicide attempts. Those who attempted impulsive suicide showed 1.32 times higher subjective health perception scores than those who attempted planned suicide, indicating adolescents who perceived they were not healthy were more likely to attempt planned suicide. BMI and subjective academic performance did not have a significant effect on the types of youth suicide attempts. These findings suggested the necessity of systematic intervention in Home Economics classes or extra-curricular programs, to prevent potential youth suicide attempts.
