Objectives: The purpose of this study was to compare oral symptoms in middle school and high school students of multicultural and ordinary families in Korea. Methods: We used data from the web-based survey of the National 2014 Korean Youth Risk Behavior of Korean Center for Disease Control. A total of 71,174 subjects responded about their father or mother's Korean nationality. We classified a subject as an adolescent of a multicultural family if aparticipant's father or mother's nationality was not Korean. Data was analyzed using SPSS Ver. 19.0. Results: High school students of multicultural families have experienced more oral disease symptoms, compared to high school students of ordinary families. After adjusting general characteristics and oral health behaviors, high school students of multicultural families experienced 1.78 times higher frequency of oral disease symptoms compared to high school students of ordinary families. Conclusions: The family type and age characteristics of adolescents should be considered when establishing policies and institutions targeting adolescents to improve oral health.

The objective of this research is to understand the current field and composition of environment related terminology used in middle and high school textbooks, to find out uniformity and relationship between them, and development for the future establishement and replacement in the environmental education, simultaneously. The results of this study are as follows: 1. The terms used in middle school textbooks were found out to be 334, while those used in high school were 717. Total terms used were 870(759 kinds) and those recorded in the environmental terminology dictionary were 362 including synonyms. 2. Of those 870, 211 terms (24.25%) which were the same words have been used in interlinked connection with the Middle and High schools. While 136 terms(15.63%) have been used in the only middle, and 524 terms(60.23%) have been used in the only high schools. In middle and high school environmental text books 211 (24.25%) terms were the same interlinked terms. Of those extracted terms, 136(15.63%) were used in the middle school 'environmental' textbooks and in high school, 524(60.23%) were used in 'environmental science' book. These results shows that there is big gap between middle and high school contents and we will need more consideration in selecting the terms and better substance. 3. The same terminologies used in both middle and high schools were total number of 676. In those terms 257 kinds(76.26%) were used in middle school 'environmental' text books, and 563 kinds(78.52%) in high school 'environmental science' text books. Here are some details : 1) Terms used as same meaning but different in expression in middle school: 83 kinds, 192 terms (11.99%). 2) Differently expressed in the same text book : in middle school - 20 kinds(2.64%) in high school - 61 kinds(8.04%) 3) Differently expressed terms between middle and high school: 51 kinds(6.72%) 4) Same meaning in 3 expressions or more : 19 kinds 4. Of the examined terms 362(including 43 synonyms) were defined in environmental dictionary which is 41.8% of the total words. In the future specialization in utmost fields will be needed 5. When dividing those examined terms according to the middle and high school curriculum, the most terms were used in nature and pollution fields following environmental preserving, artificial environment, and environmenatal counterplan. In middle schools the most used terms were in the field of environment pollution, preservation, counterplan, and sanitation. These results reflects the education goals and objectives of middle schools. But for the middle school 'environment' curriculum moret uniform distribution are needed and for the high schools' 'environmental science' program, the fields in artificial environment, industrization, urbanization, and sanitation should be intensified.

The purpose of this paper was to understand the relationship of high school boy's satisfaction with a Korean traditional style school uniform and their attitudes and image evaluation to male regarding wearing school uniforms. A survey was administered to 128 male high school students. To find our factors of their attitudes and their images regarding wearing school uniforms, Varimax rotated factor analysis was adopted. The results showed that each few factors were identified in their wearing attitudes and images. Multiple regression analysis was to investigate the relationship between these factors and the satisfaction with their school uniform. As a result of this, if their satisfaction becomes greater, they tend to recognize the distinctive design of their school uniform and wear their school uniform on various occasions. In addition, the more they become satisfied with their school uniform, the more the students are comfortable with the uniform and recognize it as a symbol of status as well. The relationship between the factors of their wearing attitudes and satisfaction with their school uniform shows that of their satisfaction becomes greater, they recognize the school uniform as good looking, comfortable and as an intelligent image. The analysis of their attitudes and images indicates that the factor of a good looking images is correlated with all factors of their attitudes. Therefore the attitudes of high school boys toward wearing a school uniform have been changed and revealed to be different from previous research results.

The purpose of this study was to investigate the sensation seeking tendency and knitwear purchase behaviors of high school girls. The data were obtained from 475 high school girls at 6 high schools located in Daejeon. The method of study is a survey consisted of sensation seeking tendency items, knitwear purchase behavior items and demographic attribution. Data were analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS WIN 17.0 program. The results of study are as follows. First, high school girls generally liked knitwears by reason of comfort and activity. Most girls purchased the knitwears to wear ordinary casual wear(81.5%). They usually thought sweater and cardigan to be representative of knitwears. Also, they mostly purchased the knitwears of simple and active design, achromatic color, 100% cotton, and solid or simple stripe pattern. The design and price were considered as important evaluation criteria in knitwear purchase. The information sources used by them were store display, friends, and internet. Second, the knitwear purchase behaviors of high school girls showed the difference between groups with high- and low-sensation seeking tendency. The most important factor of knitwear purchase was an unique and characteristic design in high group and a simple and active design in low group. In conclusion, high school girls liked knitwears and had different knitwear purchase behaviors according to the sensation seeking tendency.

In this study, by classifying latent groups for disaster safety awareness focusing on the four sub-factors of the developed disaster awareness scale of high school students, the characteristics of each group were examined, and the differences between latent classes according to inter-individual differences were investigated. As a result of analysis based on the data of a total of 1054 high school students, the disaster safety awareness of high school students was classified into three latent groups. Each latent group was named 'High Safety Awareness Type(SAT)', 'Normal SAT', and 'Low SAT' according to its characteristics. In all four fire safety awareness sub-factors, 'High SAT', which had a high score, accounted for 56.5% of the total, and 'Normal SAT', which had a moderate score in the sub-factors, had the lowest ratio at 20.3%. There were no significant differences by gender, grade, and academic achievement of the latent group. These results are not only meaningful as the first study of the latent profile analysis of high school students on disaster safety awareness, but also help to identify the characteristics of individuals in each latent group with more subdivisions and provide useful data for disaster safety awareness education according to individual differences. The implications of this study and suggestions for follow-up studies were discussed.
