The purpose of this study is to see correlation between parental psychological control and volition control in mathematics learning of 6th grade of elementary school. This study has carried out a survey for 371 male and female students in 6th grade of elementary school in Gyeongnam. We analyzed the collected data statistically, and the results are as follows. First, there was a significant difference in the level of volition control in mathematics learning between male and female students. The level of volition control in mathematics learning was found to be higher in female groups than in male groups. Second, there was no significant difference in father and mother's psychological control level perceived by 6th grade elementary school students. Third, there was a significant negative correlation between parental psychological control and their children's level of volition control in mathematics learning. In this study, by examining the correlation between parental psychological control and volition control level in mathematics learning of elementary school students, the higher the parental psychological control, the lower the level of volition control of their children. So, that it is important to have a parenting attitude that respects their children's emotion and expression.

We proposed a-Si:H TFT (hydrogenated amorphous silicon thin film transistor) level shifter which reduced number of power sources. To reduce the number of power sources from four to two, modified bootstrapped inverter was used for the level shifter. The shift register was verified by PSPICE circuit simulation and fabricated. The fabricated level shifter successfully shifted low input (0 to 5 V) to high level output (-7 to 23 V).

Two (second-grade) classes of Yu-song middle school were chosen to research the effect of the visualization in the learning of probability calculation at a middle school. One class, as an experiment class, was taught the probability calculation of probability unit by the visualization learning and the other, as a controlled class, was taught it by the traditional lecture, and then through the writing tests there was a verification on the effect of right after test and the delaying test after 3 weeks to examine the learning effect of high- and low-level groups. It was difficult for the students to visualize the problems of the probability calculation, but I suggested simple models to the students and helped them to learn meaningfully. As a result of this study, there showed statistically significant difference in high-level group in the right after test.(P< .05) In the delaying test after 3 weeks, there also showed statistically significant marks only in high-level group.(P< .05) The visualization in the learning of probability calculation took more affirmative effect in the experiment class than the comparative class only in high-level group. The students in low-level group has difficulties in the visualization activities, but all the students in high-and low-level group thought the visualization was a great help to them in learning probability calculation.

Deep learning techniques such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) show superior performance in text classification than traditional approaches such as Support Vector Machines (SVMs) and Naïve Bayesian approaches. When using CNNs for text classification tasks, word embedding or character embedding is a step to transform words or characters to fixed size vectors before feeding them into convolutional layers. In this paper, we propose a parallel word-level and character-level embedding approach in CNNs for text classification. The proposed approach can capture word-level and character-level patterns concurrently in CNNs. To show the usefulness of proposed approach, we perform experiments with two English and three Korean text datasets. The experimental results show that character-level embedding works better in Korean and word-level embedding performs well in English. Also the experimental results reveal that the proposed approach provides better performance than traditional CNNs with word-level embedding or character-level embedding in both Korean and English documents. From more detail investigation, we find that the proposed approach tends to perform better when there is relatively small amount of data comparing to the traditional embedding approaches.

Purpose: This study aims at identifying individual- and school-level factors associated with unintentional injuries to Korean adolescents at school by applying multilevel modeling. Methods: From the database of the eleventh Korea Youth Risk Behavior Web-based Survey (KYRBS), the researchers selected 68,043 adolescents from the $7^{th}$ to the $12^{th}$ grades. Data were analyzed using ${\chi}^2$ test for prevalence and multilevel modeling for related factors of unintentional injuries at school. Results: About 22.9 percent of the adolescents had treatment experiences for unintentional injuries at school in the past 12 months. At the individual level, the significant factors associated with unintentional injuries at school included gender, grade, academic achievement, current smoking, alcohol consumption, frequency of high caffeine intake, depression, and relief of fatigue after sleep. At the group level, the significant factors included number of physical education per week and safety education. Conclusion: School based injury prevention programs should be sensitive to both individual- and school-level factors associated with unintentional injury at school among Korean adolescents.

This study was designed to investigate the relationships among adolescent′s study load, peer relationships, school violence and their level of satisfaction with school life. Its purpose was not only to identify and describe their overall school life, but most importantly, to provide baseline data to develop intervention programs that shall improve the level of adolescents′satisfaction with school life. The analysis of data revealed the following results: 1. Adolescents felt highly stressed by their studies. The mean score was 3.40 out of 5 points. 2. Adolescents were highly intimate and relatively low confident with their friends, 4.28 and 3.82 respectively. 3. Approximately half of the respondents(45.4%) had an experience of making their classmates feel "exclusive". In connection, 27% had been involved in school violence. 4. The mean score of adolescents′ level of satisfaction with school life was 2.33.

The purpose of this study is to find out the level of science teaching efficacy belief in the elementary school teachers and to find out the students' science process skills and scientific attitudes according to the level of the teacher's science teaching efficacy belief. After measuring science teaching efficacy belief of 109 teachers from nine elementary schools, three teachers who received the high score and three teachers who received the low score were selected from each 5th and 6th grade. Science process skills and scientific attitudes of 331 students who were in the selected 12 teachers' classes were measured. The results of this study were as follows; First, there were significant differences on the elementary school teachers' science teaching efficacy belief according to teacher's gender and career. The men's average score was clearly higher than women's average score on personal science teaching efficacy in science teaching efficacy belief according to teacher's gender. There was a obvious difference between the group of more than six-year less than ten-year and the group of more than fifteen-year less than twenty-year, the group of more than twenty-year on science teaching outcome expectancy in science teaching efficacy belief according to teacher's career. Second, there was not a evident difference on the elementary school students' science process skill according to the level of the elementary school teachers' science teaching efficacy. Third, there was a distinct difference on the elementary school students' scientific attitude according to the elementary school teachers' science teaching efficacy. There was a significant difference on the openness and the endurance in each scientific attitude. The level of science teaching efficacy belief in the elementary school teachers had few effects on the elementary school students' science process skill, on the other hand the level of science teaching efficacy belief in the elementary school teachers had an positive effect on the elementary school students' scientific attitude.

Objectives: This study aims to evaluate the impact of patient-physician communication curriculum on students of Korean medical school in terms of cognitive, affective, and psychomotor level of communication skills. Methods: A communication curriculum was developed considering COVID-19 pandemic situation. Lectures, peer role-play, open interview with standardized patient (SP), discussion and feedback were conducted by online, and face-to-face 1:1 SP-interview was performed. Scores of written test, peer role-play of medical communication, SP-interview, self-evaluation on one's interview with real patients in clinical clerkship, and questionnaire of importance were collected and analyzed. Results: Converted to 100 point scale, the mean score of written test (cognitive level) was 91.2 while that of importance questionnaire (affective level) was 77.5. The mean scores of psychomotor level were 72.5, 77.5, and 62.5 for peer role-play, SP-interview, and real patient interview in clerkship, respectively. Conclusions: Students' performance is lower in higher level of competence. Curriculums should provide more opportunities of practices to students, and include evaluation focusing on performance skills.
