SQL is the most common language in data processing. Therefore, most of the colleges offer SQL in their curriculum. In this research, an auto scoring SQL test is proposed for the efficient results of SQL education. The system was treated with algorithms instead of using expensive DBMS(Data Base Management System) for automatic scoring, and satisfactory results were produced. For this system, the test question bank was established out of 'personnel management' and 'academic management'. It provides users with different sets of test each time. Scoring was done by dividing tables into two sections. The one that does not change the table(select) and the other that actually changes the table(update, insert, delete). In the case of a search, the answer and response were executed at first and then the results were compared and processed, the user's answers are evaluated by comparing the table with the correct answer. Modification, insertion, and deletion of table actually changes the data table, so data was restored by using ROLLBACK command. This system was implemented and tested 772 times on the 88 students in Computer Information Division of our college. The results of the implementation show that the average scoring time for a test consisting of 10 questions is 0.052 seconds, and the performance of this system is distinguished considering that multiple responses cannot be processed at the same time by a human grader, we want to develop a problem system that takes into account the difficulty of the problem into account near future.

The purpose of this study was to examine the effects of Adlerian Encouragement Program on the interpersonal satisfaction, self-efficacy and self-esteem among elementary school students. The program was consisted of 8 sessions: 1^st session was for introducing programs and making positive nicknames, 2^nd~5^th sessions were for abandoning inferiority and discouraged thoughts, displaying posters of success experiences, creating merit trees, 6^th~7^th sessions were for self-encouragement and other people encouragement, 8^th session was for closing the program. Subjects were 40 students who were the fifth grader students at I elementary school in G city. The subjects were divided into an experimental group(N=21) and a control group(N=19). All participants were asked to complete the Interpersonal Satisfaction scale(Kim, 2010), Self-efficacy scale(Han, 2003) and Self-esteem scale(Choi & Jeon, 1993). The pretest and post-test were taken in order to verify the effectiveness of the program. The data were analyzed with ANCOVA. The results are as follows: the Adlerian Encouragement Program had a significant impact on interpersonal satisfaction and self-esteem but didn't show a significant impact on self-efficacy. The study confirmed that the Adlerian Encouragement Program had a significant effect on interpersonal satisfaction and self-esteem of elementary school students, suggesting the encouragement, a key technique in Adlerian psychology, is an important educational philosophy and method for healthy development and democratic class management.

This paper is based on the effects of Zone of Proximal Development and scaffolding theory of social constructivist, Russian psychologist Vygotsky. He insisted that a social interaction play a fundamental role in the development of cognition. This study is to examine the efficient of the scaffolding types in Math class. The ZPD is the distance between a student's ability to perform a task under adult guidances or with peer collaboration and the student's ability solving the problem independently. To conduct the research was grouped into an experimental first grader five students in H high school in Y county. After class, students were questioned through Semi-structured interviews. The results of this study are below. First, Students were satisfied with the class mixed micro-scaffolding types and Macro-scaffolding types and improved their math thinking ability and the ways of solving problems. Second, The results of the class showed that students' ability to perform a task was transferred to the higher level through the help of a teacher or peers. Students could have more time to listen to peers' opinions and to say their own thoughts freely than they were under the lecture method instruction. Third, Students were interested in math through the experimental class. That's because the appropriate help of the scaffolding type, a cooperate study, relative with real life, using an engineering tools. They made a change of perception.

Objectives The Eum-Yang (Yin-Yang in English) temperament was shown to have clinical and structural validity with Sasang Personality Questionnaire (SPQ), however the studies of the association with behavior problems and personality structure in adolescents were not satisfactory. The purpose of this study was to examine the relationships between Eum-Yang temperament and behavior problems in Korean middle school students. Methods 122 first grader of middle school students (68 boys and 54 girls) completed SPQ, Junior version of Temperament and Character Inventory (JTCI), and Youth Self Report (YSR). The correlations between SPQ, JTCI, and YSR subscales were investigated. And, also the differences between SPQ, JTCI, and YSR subscales among Yang (high 30% of SPQ total score) and Eum (low 30% of SPQ total score) temperament groups classified with SPQ total score were examined. Results The SPQ total score were correlated with Novelty-Seeking (r=.321) and Reward-Dependence (r=.392) in boys, and with Novelty-Seeking (r=.427) and Harm-Avoidance (r=-.444) in girls. The SPQ total score were not significantly correlated with Body Mass Index, Ponderal Index and YSR total, however significantly correlated with YSR Internalizing problems and Withdrawal/depressed subscale (r=-.242 and r=-.419) in boys and Withdrawal/depressed subscale (r=-.449) in girls. There were significant differences between Eum and Yang groups in Novelty-Seeking, Harm-Avoidance and Withdrawal/depressed as for boys and girls. Conclusions The biopsychological structure of SPQ was confirmed with middle school students. The behavioral (SPQ-B) and emotional (SPQ-E) perspectives of Eum-Yang were found to be protective and risk factors, and also correlated with Externalizing and Internalizing behavior problems, respectively. The biopsychological characteristics of Eum-Yang temperament and its relation with psychopathological symptoms in late-childhood should be carefully analyzed.

The purpose of this study was to investigate about the effects of parental rearing behavior on self-esteem and gender role stereotype during adolescence and to reveal the mediating effect of self-esteem on adolescents' gender role strerotype. Also investigated the relationship among these variables and condition variables. For this purpose, used the Second Grade longitudianl Panel data of Middle School from the Korea Youth Panel Survay(KYPS). And the latent growth model was analyzed 3,449 men and women adolescents' cases of the first, the fourth and the sixth wave of the Korea Youth Panel Survey(KYPS) administered by Korea Institute for Youth development. And the structural equation model was used to investigate whether self-esteem mediates parental rearing behavior and male and female gender role Strerotype. The results of this study, the direct effect between variable factors showed that the more positive the parenting behavior of the second grader of middle school is, the more positive the self-esteem of male adolescents and the initial value of stereotypes of male gender role. It also affects the self-esteem of female adolescents and stereotypes of female gender roles but not statistically significant. The male gender role stereotypes were decreased in influence by the rate of change of parental rearing behaviors, and the initial value and the rate of change of self-esteem were statistically influenced to the male gender role stereotypes and the higher the self-esteem, the higher the self-esteem. However, there was no significant effect on stereotypes of female gender roles. As a result of analyzing the mediating effect of self-esteem, partially mediated between the initial value of parental rearing behavior and initial stereotype of male gender role, but there was no longitudinal mediation effect. There was no mediating effect of self-esteem between parental rearing behaviors and stereotypes of female gender roles and there was no longitudinal mediation effect. The effect of condition variable gender was found that female adolescents are more affected by paretal rearing behavior than male adolescents and also affected by the growth process. The monthly income of households influenced the initial value of parental rearing behaviors and showed a difference in parental rearing behavior according to household income. And the higher the mother 's educational level, the more the self-esteem of male adolescents was affected.

The purpose of this study was to look into how social support for high school students was affecting suicidal ideation and verify how the moderating effect worked on risk factors in the relationship between social support and suicidal ideation. Specifically, three sub-factors of social support were classified into friend support, teacher support, and parent support, and were set as independent variables. In addition, suicidal ideation was dependent variables, gender, grade level, and school type as moderating variables. The main research results are as follows. First, teacher support, friend support, and parent support all appeared to have a significant negative effect on suicidal ideation. Second, the suicidal thoughts were higher in female students than in male students than in male students and in students of general high school than in those of vocational high school. Third, support from friends and parents was more effects in reducing suicidal thoughts for female students than male students. Fourth, the effect that teacher support that support and parent support reduce suicidal thoughts was greater for first graders than second graders. Bases on the results of the analysis, interviews were also conducted with high school teachers. Through the results of this study, I would like to propose practical measures to alleviate social problems related to suicide in high school students and to provide basic data for policy measures.

This survey was conducted to investigate the present status of farm tractor utilization for obtaining a basic reference to the establishment of the government's agricultural mechanization strategies. Thirty two counties from the eight provinces except Jeju were covered in this study. From these selected areas, 433 sample farms having farm tractor were taken to obtain the general informations by the enquete, and 93 sample farms among them to investigate the status of daily tractor use in the year of 1980. The analyzed results are summarized as follows: 1. Farm tractors owned by the rice-oriented farms holds 71.5 percent of the total number of tractors the livestock-oriented farms 17.0 percent, and the orchard-oriented farms 7.0 percent. Among the farm tractors 64.3 percent was a large size (46ps) and 35.7 percent a small size(19~23ps). 2. Most of the tractors surveyed were equipped with the essential attachments such as plow and rotavator. About 18 percent of the tractor owners had no trailer, which seemed too high considering the large percentage of tractor use for transportation. The availability of other attachments was very low except a grader on the rice-oriented farms and a hay harvester and a front loader on the livestock-oriented farms. 3. The average size of farm was 3.9 hectare for the rice-oriented farms, 13.9 hectare for the livestock-oriented farms and 7.4 hectare for the orchard-oriented farms. It was obious that the average farm size of was too small compared to the theoretical machine capacity of the tractors. 4. About 70 percent of the tractor operators were in the age of twenties and thirties. About 90 percent of them had an educational level of middle school graduate or above even though their technical level was very low. 5. Any particular problem in tractor use was not found in this survey. From the farmer's preference for purchasing a new tractor, however, it is estimated the demand on a 20-30ps tractor will be more increased. 6. The average annual use of tractor was of about 100 days or 400 hours. It appeared that the rice-oriented farms used most with 412.4 hours per year, and followed by the livestock-oriented farms with 403.6 hours, the orchard oriented farms with 377.7 hours. 7. Among the total hours of tractor use, 47.3 percent was for transportation, and 41.6 percent was for plowing and rotary tillage. The largest portion of the annual tractor use was taken by transportation on the livestock-oriented farms, by land preperation on the rice-oriented farms, and by loading and chemical spraying on the orchard-oriented farms. 8. The hours of tractor use had a peak in May. The hours of use for own farm was remarkably different among the different farm oriented, but there was no considerable difference between the too different sizes of tractor. 9. The hours of tractor use decreased as the age of the operator or the educational level increased. The reason might be that the operators who had a high educational level or were older had a tendency of disliking custom works. 10. The average custom use of tractor was 171.3 hours per year, and the ratio of custom work was 63.7 percent on the rice-oriented farms, 31.7 percent on the livestock-oriented farms and 22.4 percent on the orchard-oriented farms. Among the custom works, the most popular one was the grader leveling. 11. The charge on custom work was about 40,000 Won per hectare for plowing and rotary tillage, and it was the most expensive in the southeastern region, and next followed by the southwestern region. 12. The average plowing capacity of the small tractor was 7.8 hours per hectare in the paddy field, and that of the large tractors was 4.3 hours per hectare. The average rotary-tilling capacities of the small and the large tractors were 6.5 and 4.3 hours per hectare, in the paddy field respectively.
