This study conducted a comparison analysis of the differences by scope between juvenile delinquents, under sentence of juvenile protective disposition, and normal middle high school boys' self-esteem and sociality; it aims to search for the correctional policy to prevent juvenile delinquency. I conducted a survey, as a sampling target, of students (84) at Daedeok Juvenile Reformatory, located in Daejeon-si, Korea, and the normal middle high school boys (230). The results of analysis showed that in the analysis of self-esteem difference, juvenile delinquents were found high in the global self-esteem and school-academic self-esteem, but the normal adolescents were found high only in the scope of family-parents self-esteem. In leadership, a subordinate scope of sociality, juvenile delinquents showed the high result, and in independence and cooperativity, normal adolescents were found high. In conclusion, as the distinction between self-esteem and sociality is different by scope, depending on the individual's characteristic and environment, it suggests that the correctional policy through the customized plan is effective at preventing delinquency.

I made the three main estimated head about the facility of mechanical pencil which we always use in normal days. The head are these, the first is apparent usability by experiment, the second is the feeling when grasping, the third is the feeling when writing. After making the head, 1 selected the head which give the effect to the facility and make sure the interaction between heads by the method of actual test with 36 samples. After this test, 1 can find that there is no high interaction between the facility and the intuitively feeling by experiment. It's because the expectation which was made by experiment for the facility is higher than the real. but there is high interaction between the feeling of wearing and the feeling of writing. The mechanical pencil which has good facility is that the total length is long(169mm), the thickness is big($\Phi$8.5mm), the weight is little bit heavy(21.4g), the intersection is not circle, the surface where is hold by fingers has across grooves, and the body is glossy.

To investigate the characteristics of $Gammakgeolli$ to which processed forms of persimmon were added, $Gokkam$, $Gammalaengi$, whole powder, peel powder, and paste were used as various processed forms. The moisture, total polyphenol, and soluble-solid contents of the persimmon used for making $Gammakgeolli$ showed a big difference according to the processed form of persimmon, and influenced the total polyphenol and alcohol contents of the $Gammakgeolli$. The pH and total acid of the $Gammakgeolli$, which were 3.7~4.1 and 0.20~0.29% (w/v), respectively, were similar to those of commercial $Makgeolli$. The amino acidity increased on the fifth day after fermentation from that on the third day, and showed relatively high levels in the whole power, peel power, and paste. The volatile-acid contents of the $Gammakgeolli$s were within the range of 80~100 ppm and showed the highest level in the persimmon-paste-treated sample. Among the major organic acids of $Gammakgeolli$ (oxalic, citric, tartaric, malic, succinic, lactic, and acetic acid), lactic acid had the highest concentration. The $Gammakgeolli$ to which hole power or paste was added showed a high level of yellowness and a good color in the sensatory evaluation. In the sensory evaluation (selection rate) of the taste and overall acceptability, the $Gammakgeolli$ treated with $Gammalaengi$ was the best.

To extend the potential benefits of error, the current study examined factors that affect students' error perception in the classroom. An experimental design was used to measure relations of classroom goal structure, feedback, and social relationships on students' perception of error. A total of 316 fourth-, fifth-, and sixth-grade elementary students participated as part of their regular class curriculum. Self-reported questionnaires were administered to measure students' perception of errors and relationships with teacher and peers, and then students were manipulated by classroom goal structure and feedback. Multiple regression analysis results suggested that students' perception of learning from error was affected mostly by relationships with peers, followed by relationships with teacher and the type of feedback. Students' perception of risk taking for error was also affected by relationships with peers and teacher, followed by the classroom goal structure. However, classroom goal structure and feedback did not affect their perception of thinking about error to improve their learning as well as error strain. These results imply how the classroom climate should be structured to improve perception of errors to improve student's learning.

이 연구는 고령화 사회의 도래에 따른 위기의 상황에서 농촌노인들의 삶의 질의 측면에서 가족 및 사회적 관계는 어떠하며, 심각한 사회문제로 대두되고 있는 농촌노인들의 복지정책의 문제점을 살펴보고자 한다. 농촌노인의 삶의 질을 살펴보기 위하여, 농촌 노인의 가족구성을 살펴본 결과 농촌노인들은 노부부만 거주하는 비율이 가장 높고(39.0%), 결혼한 아들 가족과 함께 사는 경우(27.3%), 독거(21.2%), 미혼자녀와 함께 사는(7.9%) 순으로 높은 비율을 보이고 있다. 사회적 관계는 따로 사는 자녀와의 관계가 가장 높으며(97.1%), 그 다음으로는 친한 친구나 이웃이 있고(94.8%), 자주 왕래하는 비동거 자녀는 평균 2.4명, 친척은 약 3명, 친구나 이웃은 5.5명으로 총 약 10여명의 가까운 사람들과 교류하여 사회적 관계가 비교적 높은 편으로 나타나고 있다(농림부, 2002). 농촌노인의 삶의 질은 가족간의 관계가 아주 중요한 지원 체계로서 자녀와 동거하는 농촌노인들은 단독가구 노인에 비해 높은 생활만족도, 높은 행복감, 낮은 고독감을 보이는 것으로 나타나고 있고(한경혜, 2003), 노인의 사회적 지원 망의 크기가 크고 다양할수록 노인의 생활 만족도나 심리적 복지감에 긍정적인 영향을 미친다고 한다.

Purpose of study: The purpose of this study is to explore the moderating effect of learning motivation in the effect of cognitive presence on cognitive regulation. Research content and method: The subjects of this study were 160 preservice teachers who are enrolled in the Faculty of Education of a university. The survey measured cognitive control, human presence, and learning motivation. Among the collected data, learning motivation was averaged. In addition, a group with low learning motivation and a group with high motivation were distinguished. Next, this study compared the averages of cognitive control by classifying the learning motivation levels. The collected data was analyzed using a multiple regression (Stepwise) method to explore the effect of cognitive presence on cognitive control. First, multiple regression analysis was performed on the entire group. Second, multiple regression analysis was performed by dividing the group with low learning motivation from the group with high motivation. Conclusions and Suggestions: As a result of the analysis, the group with high learning motivation showed a higher level of cognitive control than the group with low motivation. In the group with high learning motivation, only content understanding among the sub-factors of cognitive presence had an effect on cognitive control. In the group with low learning motivation, all factors of cognitive presence were affected.

The purpose of this study is to establish a model for predicting academic achievement of college students and to reveal the interrelationship and relative influence of each factor. For this, we surveyed the personal factors and learning strategy factors of 1,310 learners at J University, and analyzed the discriminant factors and patterns of the predictors of academic achievement through the decision tree analysis, a data mining method, and examined the relative effects of each factor. Binary logistic regression analysis was performed for viewing. As a result, the most important factor for predicting academic achievement was efficacy, and other factors such as motivation, time management, and depression were predictive of academic achievement. The patterns of factors predicting academic achievement were found to be high in efficacy and time management, and high in motivation for learning even if the efficacy was moderate. Low efficacy and learning motivation, and high depression have been shown to decrease academic achievement. Based on these results, the study suggested the efficacy and motivation to improve academic achievement of college students, strengthening time management education, and managing negative emotions.

The purpose of this study was to confirm how the students have responded to their class according to STEB (science teaching efficacy belief) of secondary science teacher in astronomy classes. Middle school teachers in charge of 'The Solar System' and 'The Exosphere and Space Development' in the 2009 Revision Science Curriculum content system is selected as an object of study through random sampling method. Twenty-nine teachers were taken STEB questionnaire and asked to make it out. Twenty-seven completed a questionnaire of them is selected for this study. In addition, the top and bottom 5% selected through frequency analysis with the total score from the questionnaire were regarded as high and low STEB teachers. For data collection, this study was used methods such as semi-structured interviews, recording, participant observation. The results were as follows: First, science teachers of high STEB had a high accessibility about excellent professional knowledge and content of the curriculum relating to astronomical field. Second, high STEB teachers were prepared by the appropriate teaching strategies adequate to student-centered learning, whereas the low STEB teachers totally have had teacher-centered learning. Third, high STEB teachers had been provided as the idea that you can take advantage of a variety of instruments, as well as scientific knowledge through the Astronomical Society. Therefore, confidence in astronomical class and teaching strategies through content of the curriculum were very important variables to predict the STEB as well as astronomy-related class activities such as astronomical observations.

This study explored the effectiveness of science teaching practice and science teaching efficacy beliefs by development of elementary school teachers' pedagogical content knowledge. Three research questions are formulated: 1) Is there any relationship between the development of teachers' pedagogical content knowledge and the science teaching efficacy beliefs? 2) How does the development of teachers' pedagogical content knowledge affect the science teaching practice? 3) How do the science teaching efficacy beliefs affect the science teaching practice? 120 subjects were chosen in 53 public elementary schools. Quantitative and qualitative data were collected and analyzed to triangulate the results. Results indicate that the development of teachers' pedagogical content knowledge and science teaching efficacy beliefs are more developed in accordance with teachers' teaching career and academic career are increased. There are significant relationships between teachers' science pedagogical content knowledge and science teaching efficacy beliefs. The more the teachers' pedagogical content knowledge, the more confident in science teaching practice. The more the science teaching efficacy beliefs, the more confident in science teaching practice. Also these teachers tried to present teaching objectives and learning problems in the beginning stages of science lessons, and they tried to review each learning stage.

This study investigated how parents' parenting attitude and youth's subjective class identification influence on game addiction. Total 177 youths from 16 to 24 participated an online survey. According to the results, parents' excessive expectation and youths' high level of self-control were associated with low level of game addiction. We divided a total into two groups; low subjective class identification group vs. high subjective class identification group based on the subjective class identification(SCI) scores. In low SCI group, excessive expectation and high level of self-control were associated with low level of game addiction. On the contrary, in high SCI group, only interference was associated with low level of game addiction. Parents' certain parenting attitude variables and individuals' level of SCI is strongly related to addictive use of game media and other various type of new media.
