This study intended to investigate the characteristics of adolescent drug user in Korea. A questionnaire on adolescent drug use was administered to 1st or 2nd grade 898 students (465 males, 433 females) from 9 senior high schools in Seoul area. The extent of current using six representative drugs such as cigarettes, alcohol, chemical substance inducing hallucination(e,g., thinner, bond etc.), psychostimulant, hypnotic and minor tranqulizer was self-reported. Also their psychological distress, self-concept and individual-related variables such as academic grade, deviant behavior, drug-using peers, the perceived availability of drugs, the degree of family discipline, and the perceived parents' attitude for drinking and smoking were surveyed. Subjects were grouped into six(male) or five(female) subgroups (nonuser, simple experiencer, one kind of drug user, two kinds of drugs user, three kinds of drugs user(male only), minor tranqulizer user) to their extent of drug use. Then ANOVA procedure performed for group comparison of their psychological distress, self-concept and individual-related variables. The results showed that the most popular drugs among adolescents in Korea were cigarettes and alcohol. Minor tranqulizer was used by about 2.8% of male and 7.41% of female subjects. In general abusers showed lower academic grade, more deviant experiences, having more drug-using peers, higher degree of psychological distress, and lower postitive self-concept than nonuser group. According to the results of discriminant analysis, hostility and deviant behavior were reliable predictive variables that distinguished abuser group from nonuser group among the associated variables in this study. These results suggest that some common factors affect drug use of Korean high school students : high school students who have many common risk factors could be abusers more easily. These findings supported risk factor theory that the extent of drug use of adolescents might be associated with general maladjustment in everyday life.

The purposes of this study were to investigate the actual condition and to deal with the psychological characteristics of computer addicted adolescent using the Minnesota Multiphasic Personality Inventory (MMPI). The subjects of this study were 407(male 185, female 222) 2nd grade students in senior high school in Daegu. All participant were evaluated on the basis of the Minnesota Multiphasic Personality Inventory (MMPI) and the upgraded Computer Addiction Inventory (CAI) scale which referred to the Young's Internet Addiction Self Diagnosis Scale and the Mind Test's Came Addiction. SPSS version 10.0 was used for data analysis. The scores of F, Hs, D, Pd, Pa, Pt, Sc of the MMPI scales showed that there were statistically significant differences between computer addicted adolescents and non-addicted adolescents. The rate of addicted adolescents was significantly higher than that of non-addicted adolescent in psychological problematic score ranges in the scales. The characteristics of the scores of computer addiction adolescents were similar to those of alcohol and drug addicts in the scales of D, Pd, and Pt. This survey revealed that the psychological disorders suffered by computer addiction adolescents may cause more serious social problems than alcohol and drug addicts.

The purposes of this study were to investigate the actual conditions and deal with the psychological characteristics of adolescent cellular phone addicts through the Minnesota Multiphase Personality Inventory (MMPI). The subjects of this study were 407 senior high school students (male 185, female 222) in 2nd grade in Daegu. The cellular phone addiction inventory (CPAI) was designed on the basis of an interview process, referring to the Young's Internet Addiction Self Diagnosis Scale. SPSS version 10.0 was employed for data analysis. The mean score of the adolescent addict group was significantly higher than the non-addict group in Scale Pd, Pa, Pt, Sc and Ma. This result indicates that the cellular phone addict group is likely to suffer from more serious pathological disorders than the non-addict group. The rate of addictive adolescents was significantly higher in the addict group than in the non-addict group in psychological problematic score ranges in Scale Sc (Schizophrenia) and Ma (Hypomania). The study result suggests that adolescents who addictively use a cellular phone will be more likely to show immaturity, instability, impulsive personality, excessive activities, and escapism.

In this study, we analyzed the causes of decrease in the number of students taking Chemistry ? in the College Scholastics Ability Test (CSAT) by analyzing the adequacy of the Chemistry I question in the CSAT and the recognition survey of students and teachers about the Chemistry I choice. We analyzed some questions in Chemistry I of the CSAT from the year 2014 to 2016. The questions were analyzed to determine whether they were appropriate to the curriculum content, achievement standard, and achievement level. The target of the survey for perception was 452 senior high school students and 68 science teachers. The result of the study showed that the questions in Chemistry I are somewhat difficult compared to the depth and achievement level required by the curriculum, and it also requires mathematical thinking ability. Students recognized the mathematical thinking and complex mathematical skills are needed to solve problems in Chemistry I. Teachers also thought that the choice of Chemistry I is unfavorable in aspect of meeting the minimum academic ability standard, and accordingly, they did not actively recommend students to take Chemistry I. Moreover, most of the teachers recognized that it is necessary to improve the direction of writing questions for Chemistry I. Therefore, setting questions that can be solved using chemical knowledge, not mathematical ability need to be addressed.

The purpose of this study is to investigate the influences of Science Core schools on students' positive experiences about science (PES) through in-depth interviews with teachers in charge of science core schools. In-depth interviews with teachers were conducted to explore the factors that led to the effectiveness of science core schools in improving the student's PES in light of operational characteristics of science core schools as leading schools, characteristic factors of science core schools on students PES, and improvement plans and requirements of science core schools as leading schools, as well as implications for general high schools. In the case of science core schools, the teacher's enthusiasm for science teaching encouraged students' participation in science classes, promoted students' interest in science other than science-core classes, improved students' inquiry and research skills, increased students' competencies such as communications and collaboration by improving science instructions, and affected career search and exploration based on interests in science experiences. Based on the results, ways to spread the characteristics of science core schools to general schools' curriculum implementation are suggested including providing opportunities to experience the value of science study, to experience science and engineering careers through senior students, to participate in team projects and self-regulated science inquires, and so on.

This paper is a result from validation study for SPDA(A Screening Scale For Potential Drug-use Adolescents) created in 2003 and newly developed during 2004. SPDA aims to screen adolescents in their early stage of drug-use and to help practitioners make a preventive approach for the adolescents. 4307 junior and senior high school students were selected as primary research subjects by stratified and quota sampling methods. 305 adolescents on probation were also selected as a comparison group and asked to answer the same questionnaire. Reliability for SPDA recorded 0.914, which proved to be better than previous year's (0.898). Exploratory and confirmatory factor analyses to test construct validity proved that SPDA could be divided into 7 factors and that each factor structure of SPDA could be a proper measurement model with high level of fitness and factor loadings. Discriminant analysis to test predictive validity confirmed that SPDA could classify the adolescents excellently by the frequency of drug-use, with hit ratio of 86.6 percent(78.8% and 87.4% for junior and senior high school students respectively). For concurrent validity test, Hare Home Self-Esteem Scale, Hare School Self-Esteem, Zuckerman-Kuhlman Sensation-seeking Scale were employed to find correlation with SPDA and all the three scales had significant Pearson correlation coefficients with SPDA. Known-groups validity test indicated that SPDA had an adequate power to classify out adolescents on probation from those in schooling, with a hit ratio of 71.8 percent. Cut-off point to detect adolescents with high risk of substance use was 77, which indicated approximately T score, 55 (0.5 SD), satisfying sensitivity, specificity, and efficiency criteria.

This study is to verify relative influence of individual, parent, peer, teacher-related variables as protective factors and risk factors of academic hatred. Surveys were conducted with 1,015 (women, 57.3%) high school third grade students across eight schools where are located in Seoul, Incheon, and Geyonggi province. Correlation analysis and hierarchical multiple regression analysis were performed. The findings are summarized as follows. Teacher's academic pressure did not have significant correlation with student's basic psychological needs, teacher's autonomy support, teacher's support, and peer support whereas other variables showed significant correlation each others. The hierarchical multiple regression analysis indicated that student's individual competence and autonomy, parent's academic support, and teacher's emotional support work as protective factors and that parent's academic pressure functions as a risk factor. The effects of peer support disappeared when teacher-related factors were included. In addition, the effects of teacher's autonomy support disappeared, while the effects of teacher's support strengthened when learner's basic psychological needs were input. This study is meaningful in that it clarified academic hatred which had not been studied in other research and that it provided theoretical foundation for subsequent studies on academic hatred by examining relative influence of related variables. Lastly, it presented its limitation, implications on intervening strategies in school counseling, and suggestions for later studies.

This study hypothesizes that the present deadlock situation in public library development in Korea has chiefly been caused by the underdevelopment of the consciousness of the librarians themselves presently employed in various levels of public libraries throughout the country. This study, therefore, aims to define the areas in librarians' consciousness in which elements of backwardness prevail, and thereby to produce a theoretical framework to develop public library services in Korea on an indigenous footing. To do this, the present author set up a relationship between the traditional consciousness of the Korean People and the public library performances, based on existing published materials. In order to prove hisirelatonship, he then sent out questionnaires to public librarians and male high school students and analyzed the answered questionnaires using Pearson's Correlation Analysis and Multiple Regression Analysis. Results of the analysis are asfollows: 1) Those who place an importance on the show of respectability tend to prefer to work in an indirect services area. 2) Male librarians tend to show a job satisfaction because of chances of promotion reflecting a positive correlation between this-worldiness of librarians and their job satisfaction. 3) Male librarians tend to be satisfied in their job for the conviction for their self-accomplishment, and female librarians tend to be satisfied in their job for the attention and respect they receive from users. 4) Library technicians tend to draw their job satisfaction from their sense of job stability. 5) Male librarians tend to be dissatisfied for the lack of the monetary rewards they receive, while female librarians tend to be dissatisfied for the lack of promotional chances. 6) Most librarians tend to maintain a positive job attitude for the promotional chances, reflecting a positive correlation between this­worldliness in librarians and their service attitude. 7) Power-orientednes in librarians and their job satisfaction correlate negatively in the case of male librarians. This does not apply to female librarians. 8) Power-orientedness and good service attitude correlate negatively in the case of male librarians. This does not apply to female librarians. 9) The fact that male high school students desire to enter good colleges and universities and to obtain a position in his job positively correlate to the fact that public libraries have transformed themselves into a mere reading room. 10) Male library science students show a maladjustment in their major department in earlier years for the professional uncertainty, and as they advance into senior years they show a positive attitude about the library profession.

Purpose: Prosthodontics education of Korean dental schools is developing under liberal regulation according to the character of each school. Diversity in the current environment and condition for each school make it impossible to apply the same and uniform education curriculum. Therefore the purpose of this paper is to analyze and validate the status of the 2012 prosthodontics education curriculum in Korean dental schools, and to suggest future direction. Materials and methods: A survey was completed by all the 11 dental schools in South Korea. Results: The number of students, age, sex, credits for prosthodontics lecture and practice courses, evaluation method before senior students' clinical practice, modalities for minimum requirement for graduation, beginning and finishing timing of clinical practice and faculty personnel involved in the education varied among the dental schools. Conclusion: High-quality educators leading an expanded teaching personnel are required, education hours must be increased and efficient curriculum must be organized to improve the prosthodontics education.

The current mathematics curriculum are consist of the following domains: 'Characteristics', 'Objectives', 'Contents', 'Teaching and learning method', and 'Assessment'. The mathematics standards which students have to learn in the school are presented in the domain of 'Contents'. 'Contents' are consist of the following sub-domains: 'Number and Operation', 'Geometric Figures', 'Measures', 'Probability and Statistics', and 'Pattern and Problem-Solving' (Elementary School); 'Number and Operation', 'Geometry', 'Letter and Formula', 'Function', and 'Probability and Statistics' (Junior and Senior High School). These sub-domains of 'Contents' are dealing with mathematical subjects, except 'Problem-Solving' at the elementary school level. In this study, the sub-domain of 'mathematical process' was suggested in an equal position to the typical sub-domains of 'Contents'.
