The purpose of this study was to examine the size, form of dental arch and occlusion type in college students in our country and the relationship of the factors. The subjects in this study were 210 selected dental hygiene students. The collected data were analyzed by a statistical package PASW 18.0. When their size, form and occlusion of dental arch were analyzed, the inter-canine width of the maxillary was 34.38 mm, and the inter-first molar width was 52.05 mm. The canine depth was 8.60 mm, and the first molar depth was 28.69 mm. As for the mandibular, the inter-canine width was 26.42 mm, and the inter-first molar width was 44.83 mm. The canine depth was 5.54 mm, and the first molar depth was 24.38 mm. Concerning the form of dental arch, the percentage of normal dental arch in the maxillary stood at 29.0, and that of crowding stood at 60.5. The percentage of spacing stood at 10.5. In the case of the mandibular, the percentage of normal dental arch stood at 29.0; crowding, 55.7; and spacing, 15.2. In relation to occlusion, the percentage of normal occlusion stood at 16.7. As to malocclusion, class I that accounted for 55.7 was most common, and class II and class III respectively accounted for 20.5 and 7.1. When the size of dental arch was compared according to the form and occlusion of it, dental arch was largest (45.95 mm) in size when the form of dental arch in the inter-first molar width of the mandibular was spacing. The size of dental arch was 44.73 mm when its form in the same region was normal, and that was 44.58 mm when its form in the same region was crowding (p=0.032). Regarding the relationship between the form and occlusion of dental arch, crowding was most common when there were class I, II and III of malocclusion both in the maxillary and mandibular.

This study investigated how collaborative reflection between novice secondary science teachers promoted the development of teaching professionalism. We intentionally selected research participants who shared sufficient rapport. Data were collected by videotaping the classes taught by participants, pre-talk, post-interviews and nine collaborative reflection processes. All data were transcribed and analyzed. Results indicated that all three teachers showed changes in teaching practice. Minyoung's practice involved a teacher-led lecture, but through collaborative reflection, she could create a learning environment to enhance students' power and ownership in her class. Emphasizing academic rigor, Soyoung used to teach content outside the scope of the curriculum, but through collaborative reflection, she became more considerate of students' understanding. Finally, in Jiyeon's classes inquiry activities and theoretical explanations were separated from each other. However, she repeated her efforts to improve her class after collaborative reflection, allowing students to construct explanations through activities. In this study, three factors that promoted the development of teachers' pedagogical content knowledge through collaborative reflection were identified. First, the different teaching orientations of the three teachers who participated in this study, promoted sharing of opinions through collaborative reflection. Second, reflection based on teaching practice enabled practical feedback on the class, which enhanced the development of teachers' pedagogical content knowledge. Third, the equal status and formation of rapport between the three teachers created an environment for productive reflection. These results suggest that future teacher education programs should target communities that can promote collaborative reflection based on teachers' teaching practice.

This study examines longitudinally influences that parents have on their children's academic achievement and the mediating role of various psychological factors. In terms of parents-child relationship, the following variables are examined: Social support from parents, achievement pressure, parental expectation, sense of indebtedness to parents, and respect for parents. For adolescents functioning, the following variables are examined: Efficacy for self-regulated learning, achievement motivation, studying time, and academic achievement. In the first phase of the longitudinal study, a total of 961 Grade 6 students completed a questionnaire. In the second phrase, a total of 856 students completed a questionnaire when they were Grade 7. In the third phrase, a total of 830 students completed a questionnaire when they were Grade 9. In the third phase, a matched sample of 722 fathers and 767 mothers of the adolescents completed a questionnaire. From the sample, 694 matched sample of adolescents, mothers, and fathers have been selected for the following analysis. The results of the path analysis indicate that adolescents' past academic grade was the most powerful predictor of adolescents' current academic achievement. Second, a sense of indebtedness felt towards the parents increased adolescents' achievement motivation, which increased their studying time and which in turn positively affected their academic achievement. Third, adolescents' respect for their parents increased their efficacy for self-regulated learning, which had a positive effect on their academic achievement. Fourth, parental social support increased adolescents' efficacy for self-regulated learning and parental achievement pressure increased adolescents' achievement motivation. Fifth, parental expectation had positive influence on adolescents' academic achievement. Sixth, efficacy for self-regulated learning had direct positive influence on academic achievement. These results indicate that the past achievement is the most important predictor of adolescents' current academic achievement and parent-child relationship and efficacy for self-regulated learning are also important variables that influence adolescents' achievement.

This study was conducted to estimate the dental caries experience, oral hygiene status and the factors influencing the dental disease in the smoking adolescents and to provide the baseline data for managing smokers efficiently. We recruited 156 smokers(male: 106, female: 50) in middle, high school students in 5 day Non-smoking program in seoul city and 176 non-smokers(male: 64, female: 112) by matching method for considering sex and age from June 1 to August 31 2009. Data on general characteristics, basic oral health care, smoking factors, self-efficiency, control of oral health, oral health promotion behavior, knowledge of oral health were collected by a questionnaire interview. DMFT index, DT index, MT index, FT index, Plaque index, Calculus index were calculated by the oral examination. The results of this study were as follows. 1. Dental clinic visit(p < 0.05), self-perception of oral health status(p < 0.001), oral health concern (p < 0.01) in non-smoker group were significantly higher than that of smoker group. 2. self-efficiency(p<0.05), oral health promotion behavior(p < 0.05) in non-smoker group were significantly higher than that of smoker group. 3. DT index, Plaque index, Calculus index in non-smoker group was significantly lower than that of smoker group(p < 0.0001). 4. The fewer smoke amount, the lower DT index(p < 0.05), Plaque index(p < 0.01), Calculus index(p < 0.001). 5. It was significant correlated among DT index and self-efficiency, oral health promotion behavior, control of oral health. 6. In multiple regression analysis, oral health promotion behavior, Plaque index was proved as a significant factors related with the degree of dental caries experience in smoking adolescents. In other word, the higher oral health promotion behavior, the lower Plaque index, the fewer DT index.

Genetic determinism of human behaviors is considered as a philosophical perspective that genes in humans determine biological as well as social traits. However, many biologists agree that human traits are determined by interactions between genes and genes, as well as between genes and environments. In this context, genetic determinism still affect ideas of the general public as well as research directions of biologists. According to Cl$\acute{e}$ment's KVP model (Cast$\acute{e}$ra & Cl$\acute{e}$ment, 2012), teachers' conceptions of genetic determinism influence students' concepts of genetics. This study intends to investigate teachers' conceptions on genetic determinism of human behaviors. For this end, a questionnaire adopted from a previous research (Cast$\acute{e}$ra & Cl$\acute{e}$ment, 2012) has been administered to 308 teachers including 151 pre-service and 157 in-service. Factor analysis has been conducted to extract major factors and one-way ANOVA has been employed to find out differences in extracted factors among different groups of teachers. Four factors have been extracted from 14 items of questionnaire, including factor 1, a perspective of genetic determinism of gender differences in intellectual ability, social status, and emotional traits; factor 2, a perspective of genetic determinism of individual differences in intellectual ability; factor 3, a perspective of genetic determinism of individual differences in biological immune function and behavioral trait; and factor 4, a perspective of genetic determinism of ethnic differences. From the results of One-way ANOVA among teacher groups on four factors, first, it has shown a significant difference in factor 1 (F=3.325, p=.006), factor 3 (F=3.320, p=.006) and factor 4 (F=4.325, p=.001) due to their subject matters. In post-hoc comparison there have been no significant difference between biology teachers and other teachers. It has also been found that there was a significant difference between pre-service and in-service teachers in factor 1 (t=-3.938, p=.000) and factor 4 (t=-3.121, p=.002) and in-service teachers are more genetic deterministic than pre-service teachers. Finally, different religions have no influence on teachers' conceptions of genetic determinism of human behaviors.

The purpose of this study was to investigate the factors affecting hearing loss in adolescent's use of PCPs, and to give the basic data for adolescent's hearing conservation program development and prevention education against their hearing loss. This study was a descriptive research about three factors affecting hearing loss; the knowledge and attitude about noise, the perception of hearing loss and the hearing threshold. The subjects of this study were 383 students in two general high schools and two vocational high schools in Teagu. They have been using PCPs but with no current or past ear disease. This study was carried out from Sep. 1. 2000 to Oct. 24, 2000. The instrument used for the knowledge and attitude about noise was a questionnaire developed by Rhee. Kyung Yong and Yi. Kwan Hyung(1996). The instrument used for the perception of hearing loss was a Smith Hearing Screening Questionnaire. A Belton Model 112 Audiometer. air-conduction hearing test instrument. was used for the hearing threshold. Data was analysed by a SPSS/Win 10.0 program with frequency. percentage, t-test. ANOVA and pearson correlation. The results of this study were as follows; 1. The average of concern about hearing scored the highest $3.66{\pm}0.70$. The average of perceived susceptibility scored $2.64{\pm}0.85$ and the average of knowledge about noise scored $2.13{\pm}0.56$. The average of total knowledge and attitude about noise scored $2.82{\pm}0.46$. The average of discomfort of hearing loss($2.51{\pm}0.81$) scored higher than that fear of hearing loss($1.35{\pm}0.53$). The average of total perception of hearing loss scored $1.93{\pm}0.59$. The hearing threshold of the subjects scored the highest at 500Hz(Lt. $23.21{\pm}6.62$, Rt. $23.39{\pm}7.02$) and scored higher in order of 1000Hz, 2000Hz, 4000Hz and 8000Hz. 2. The knowledge and attitude about noise and the perception of hearing loss were both affected only by one important characteristic, which was general and vocational high schools. The knowledge and attitude about noise raked (t=5.258, p=0.000), and perception of hearing loss raked(t=2.241. p=0.026). However. several other important characteristics also impacted significantly on the knowledge and attitudes about noise. They included grade (t = 1. 987. p=0.048), father's education(F=2.745. p=0.043), marks(F=3.157, p=0.044), drinking(t=2.307, p=0.022) and smoking(t=2.587, p=0.010). The left hearing threshold differed significantly by sex at 1000Hz(t=5.175, p<0.001) and 8000Hz (t=3.334, p<0.01). According to general and vocational high schools (p<0.001), at 500Hz (t=-5.056), 1000Hz (t=-5.253), 2000Hz (t=-4.905), 4000Hz (t=-4.704) and 8000Hz (t=-5.204) significant differences were also shown. Marks were significant at 1000Hz (F=3.824, p<0.05) and drinking was found to be significant at 500Hz(t=2.203, p<0.05). The right hearing threshold differed significantly by sex at l000Hz(t=5.557. p<0.001). 4000Hz(t=2.234. p<0.05) and 8000Hz (t=2.730. p<0.01). According to general and vocational high schools(p<0.001) at 500Hz (t=-4.730), 1000Hz(t=-6.271). 2000Hz (t=-4.573). 4000Hz(t=-3.554) and 8000Hz (t=-3.405) significant differences were also shown. Grades impacted at 500Hz(t=2.201. p<0.05) and 4000Hz(t=2.511. p<0.05), while marks were significant at l000Hz(F=4.1l5. p<0.05) and drinking was significant at 500Hz(t=2.333. p<0.05). 3. The left hearing threshold in accordance with use of PCPs differed significantly at 2000Hz(F=2.996. p=0.03l) according to volume level and at 8000Hz(F=2.197. p=0.022) according to duration${\times}$hours per day. The right hearing threshold differed significantly at l000Hz(F=3.075. p=0.028) according to volume level and at 8000Hz(F=2.925. p=0.034) according to duration. 4. The knowledge and attitudes about noise showed a light positive correlation with the perception of hearing loss. A positive correlation was shown. as stated previously in all Hz, between the left hearing threshold and the right hearing threshold, especially the highest correlation at 2000Hz(r=0.761. p=0.000). This study has shown that the factors related to adolescent's use of PCPs are important as they impact significantly an adolescent's hearing. These results then indicate that in future, when designing a hearing conservation program and prevention education this data should be considered.

Attitudes to the health and dietary life of teachers affect their students. The purpose of this study was to investigate dietary and education awareness, eating habits and dietary management competency of the preliminary teachers and teachers. Data was collected from 812 pre-service teachers and teachers in South Korea using a 5-Likert self-administrated questionnaire in October to December of 2017. Data was analyzed using factor analysis, reliability, one-way analysis of variance, and correlation. The results of this study are as follows. Dietary and education awareness was classified into dietary concern and dietary management stress. Eating habits composed of healthy eating habit and bad eating habit. Dietary management competency was sub-grouped into dietary knowledge, cooking, dietary sanitation and safety, and environment. The all factors of pre - service teachers and teachers showed a significant difference except for the environmental ability factor (p <0.01). All factors were significantly different according to the age and the number of meal preparation (p <0.05). The eating habits were not significantly differences from sex. The major and health condition showed significant differences except dietary management stress and cooking factors (p <0.01). The obesity index showed significant difference in the dietary concern, bad eating habits, and cooking factors (p <0.01). In conclusion, it was required to education and develop education materials that can help the STEAM education using the dietary area. The dietary education program for the pre - service teachers and the teachers should increase the number of participating in the meal preparation considering the difference according to the general characteristics, so that the dietary management competency and the healthy eating habits should be formed.

The objective of this study was to examine the relation between delinquency and career maturity in school adolescents and to determine whether activities for enhancing career maturity can have protective effects against juvenile delinquencies. Research questions for this study are: first, how serious school adolescents' delinquencies are; and second, what relation there is between delinquency and career maturity in school adolescents. Third, how different is school adolescents' career maturity according to their experience in delinquencies? The results of this study were as follows. First, 55.8% of the school adolescents committed one or more of the 14 types of delinquent acts included in the delinquency inventory during the last one year, and the percentage was higher among male students than among female ones. Second, no correlation was observed between the school adolescents' overall delinquency level and overall career maturity. According to the sub-factors of career maturity, however, the overall delinquency level was in a negative correlation with objectiveness and a positive correlation with independence/decisiveness. That is, objectiveness was higher in the group without experiences in delinquencies than in the group with such experiences. and Type II status offenses (truancy, runaway) was in a negative correlation with overall career maturity, and in a negative correlation with objectiveness and confidence. Third, no significant difference was observed in career maturity between those with experience in delinquencies and those without. Among the sub-factors of career maturity, however, objectiveness was higher in those without experience in delinquencies than in those with. and Overall career maturity, and objectiveness and confidence among the sub-factors of career maturity were significantly higher in those without experience in Type II (truancy, runaway) status offenses than those with. The results of this study suggest that the objectiveness of career maturity can be a protective factor against juvenile delinquency. Furthermore, they suggest that activities for enhancing career maturity may protect adolescents from Type II status offenses. These results may provide basic materials necessary to develop career counseling approaches and interventions strategies for preventing school adolescents' delinquencies.

Objectives : This study aims to examine satisfaction of dental treatment and revisit and intention of recommendation to dental patients and to supply as a basic resource for dental management improvement. Methods : 645 dental patients to dental hospitals in G City were subjects of this study. 27 dental hospitals were randomly chosen per 5 or 6 in 5 Districts. The intention of the survey was explained to 645 patients and it was agreed to have questionnaire survey. Questionnaire survey was carried out for 2 weeks in April 2011. Total 593 were used for the analysis except for insufficient answer sheets. The analysis was executed by using SPSS 18.0 and the results are as follows. Results : 1. The highest figures are as follows: female was 53.29% in sex, 20-29 age group was 44.52%, graduates of university were 38.62%, students were 28.50%, monthly family income with 300-399 million won was 31.70%. As to the treatment, dental caries were highest with 46.21% followed by scaling with 40.81%. As to the number of visit, 39.80% were over 5 times, and as to the opportunity to use, 29.34% answered it because it is close to home. 2. As to satisfaction, male was 4.15, over 60years old was 4.58, self-employed was 4.33, friendship with dentist as opportunity to use was 4.37. And as to revisit intention, over 60 years old was 4.60, over postgraduate in education level was 4.38, self-employed was 4.43, over 5 times visit was 4.32, and fame as opportunity to use was 4.39 which were the highest. As to the intention of recommendation to others, female was 4.24, over 60 years old was 4.65, self-employed was 4.36, friendship with dentist as opportunity was 4.43 which were the highest and showed significant differences (p<0.05). 3. As to patient satisfaction, there were strong relevance between revisit intention and intention of recommendation with 0.769 and 0.744 respectively. And, as to revisit intention, it had significant relation with revisit intention with 0.791. 4. The explanatory power of the regression analysis on the factors affecting revisit intention was 61.20%. The revisit intention was high when the satisfaction of dental hospital was high (${\beta}$=0.767, p<0.001), the number of visit (${\beta}$=0.026, p<0.01), reason for a visit (${\beta}$=0.070, p<0.01), education level (${\beta}$=-0.063, p<0.05) and occupation (${\beta}$=0.078, p<0.05). 5. The explanatory power of the regression analysis on the factors affecting intention of recommendation was 59.9%. The intention was taken patients satisfaction(${\beta}$=0.601, p<0.001), dental hygienist's kindness (${\beta}$=0.218, p<0.001), female (${\beta}$=0.079, p<0.05), reason for a visit(${\beta}$=-0.059, p<0.05), dissatisfaction treat(${\beta}$=0.084, p<0.05), dentist's kindness (${\beta}$=-0.080, p<0.05), age (${\beta}$=0.054, p<0.05). Conclusions : To improve revisit rate of patients, the refurbishing hospital facility, treatment and kindness of dental hygienists and satisfaction of treatment must be improved. And it also needs to accept complaint from female patients in a positive manner, and understand and correct complaints actively from the perspective of patients.
