There have been many emotion researches to investigate physiological responses on specific emotions with physiological parameters such as heart rate, blood volume flow, and skin conductance. Very few researches, however, exists by detecting them with facial skin temperature. The purpose of present study was to observe the differences of facial skin temperature by using thermal camera, when participants stimulated by monitor scenes which could evoke fear or joy. There were totally 98 of participants; undergraduate students who were in their adult age and middle, high school students who were in their adolescence. We measured their facial temperature, before and after presenting emotional stimulus to see changes between both times. Temperature values were extracted in these regions; forehead, inner corners of the eyes, bridge of the nose, end of the nose, and cheeks. Temperature values in bridge and end of the nose were significantly decreased in fear emotion stimulated. There was also significant temperature increase in the area of forehead and the inner corners of the eyes, while the temperature value in end of the nose decreased. It showed decrease in both stimulated fear and joy. These results might be described as follows: When arousal level going up, sympathetic nervous activity increases, and in turn it makes blood flow in peripheral vessels under the nose decrease. Facial temperature changes by fear or joy in this study were the same as the previous studies which measured temperature of finger tip, when participants experiencing emotions. Our results may help to develop emotion-measuring techniques and establish computer system bases which are to detect human emotions.

This study analyzed the characteristics of National Science Curricula in the UK, Australia, New Zealand, Canada, Singapore, and Korea with respect to core competencies. In the case of overseas countries, literature review on their curricula was conducted, and four common features were extracted: 'association of cross-curricular competencies with science-specific competencies', 'a combination of science contents and scientific practices', 'an emphasis on communication skills', and 'representation of an achievement level of competency'. In addition, the common core competencies of science education were 'critical thinking', 'creative thinking', 'problem solving', 'inquiry skills', 'communication skills', 'cultural literacy', 'ability to integrate discipline', 'application skills', and 'personal/social competency'. In relation to these features, this study also investigated Korean science teachers' perceptions of core competencies in science education. A survey was conducted on 135 teachers in elementary, middle, and high school in Korea. Teachers were not well aware of what core competencies are, and after introduction, they thought that they wanted to and needed to teach core competencies to their students. Teachers claimed that critical core competencies in science education are 'creative thinking', 'problem solving', and 'inquiry skills'. Teachers thought that core competencies-based science class would help develop students' scientific literacy and communication skills. However, they have difficulties in conducting core competencies-based science class because they are not familiar with how to conduct the class and they expect that it will take a long time to prepare such a class.

The new paradigm of the 21st Century science education explores a wide range of possibilities that can foster students' interest toward science and creative convergence thinking. In this study, through the analysis of programs that were developed in 'STEAM leader school' and 'STEAM teacher association for research' supported by the 'Ministry of Education, Science, and Technology,' we analyzed the linking frequency with each of STEAM education's fields and teachers' perception for the convergence strategy of technology and engineering. The results of this study show that linking frequency of technology and engineering is lower than the field of arts and mathematics in elementary school, but higher in middle and high school. 'Introduction technology contents in lives' in technology and 'crafts activity' in engineering are the most used teaching and learning strategy in STEAM education. But, although 'crafts activity' is engineering's major way of learning, many teachers understand and use it as a technological teaching learning strategy. It is important to understand that each of STEAM education's field has a unique nature and educational implications, for the effective settlement of STEAM education, we need to consider teaching and learning strategy in various way.

The purposes of this study were to develop the customized instructional programs by the causes of science underachievement and to identify the effectiveness of these programs. For these, we analyzed the characteristics of underachievers and causes of science underachievement and classified 22 7th grade science underachievers into three different types such as lack of science process skill, lack of science learning motivation, and lack of science learning strategy. They then were divided into the experimental and comparative groups. Instructional programs treated for both groups covered the same topics and were conducted once a week for 60 minutes each time for 15 weeks. Eleven students in the comparative group were treated with an activity-centered science program that dealt with basic science concepts. Unlike science underachievers in the comparative group, those in the experimental group were given customized instructional program. After the treatment, students were administered several tests including a test on awareness of the program, science process skill test, science learning motivation and strategy test, and academic science achievement test. In addition to the results of those tests, worksheets, daily activity reports, and interviews were used to evaluate a customized instructional program that was applied to the experimental group. Results of the study showed that these programs relieved science underachievers from the cause of poor achievement and accordingly help them achieve better performance in academics. In addition, both lack of learning motivation and lack of learning strategy types tended to relieve the other causes of science underachievement. Also, the experimental group showed a high level of satisfaction with the customized instructional programs.

In this study, pre-service science teachers' difficulties in teaching practice were investigated from the perspectives of pre-service teachers and cooperating teachers. Nine pre-service teachers who were attending a department of chemistry education at a college of education in Seoul and participated in teaching practice, and two of their cooperating teachers participated in the study. Teaching practice were observed, documentary data were collected, and interviews were conducted. The collected data were analyzed using analysis method of grounded theory. As results of the analysis, the pre-service teachers had difficulties in preparing and executing lessons which include experiments, because education related to experiments in middle and high schools was insufficient at the college of education and environments of cooperating school were unfamiliar to them. They had difficulties in encountering various responses from students in student-centered activities and tried to control students. Cooperating teachers did not provide specific assistance to ensure the autonomy of pre-service teachers, so that pre-service teachers suffered. Guiding science club activities was a meaningful experience to pre-service teachers, but it was a burden on both pre-service teachers and cooperating teachers. Educational implications of these findings were discussed.

This study analyzes the effects of the self-esteem on the life satisfaction of 2,040 middle school senior students using the Korean Children and Youth Panel Survey 2012 Data (KCYPS 2012) provided by the National Youth Policy Institute. In the ecological perspectives, this study considers two factors which influence the life satisfaction of the students; one factor is the environmental characteristics like parent intimacy, friend intimacy, teacher intimacy and study adaptation, and the other factor is the individual characteristics. In particular, self-esteem as one of the individual characteristics is divided into two separate categories, positive self and negative self. The two categories are found to have some interaction effects on the life satisfaction at the evaluation level. The effects of the negative self-evaluation on the life satisfaction appear to be different depending on the level of the positive self-evaluation. As the level of the positive self-evaluation becomes higher, the effects of the negative self-evaluation on the life satisfaction decreases. The life satisfaction becomes higher as the level of the negative self-evaluation is lower, and the life satisfaction is not high relatively at the low level of the positive self-evaluation. These results suggest that solving the adolescent's negative self-formation problem can not bring out the positive self-formation and there should be some plans for the positive self-formation more than simply solving the negative self- formation problem in order to improve the life satisfaction.

This study analyzes the effects of perceived parental attitude on self-esteem in elementary and junior high school students. For this purpose, a questionnaire was given to 220 students, including 5th and 6th graders in elementary schools and 7th graders in middle schools in the Gyeonggi area. A total of 188 responses to the questionnaire were analyzed after excluding 22 responses that insincere responses or missing items. Descriptive statistics were used to investigate the general characteristics of the subjects, and a t-test, ANOVA, correlation analysis, and multiple regression analysis were performed to examine the differences in parental attitude and self-esteem according to the general characteristics of the subjects. The results showed that there is a stronger relationship for mothers between parental attitude and self-esteem perceived by children than for fathers. There were no significant differences between parental attitude and self-esteem according to the grade of the children. Among the subfactors of parental attitude, affectionate attitude and overprotective attitude were found to have a positive effect on self-esteem. In particular, an affectionate attitude among fathers had a positive effect on the self-esteem of children.

The purpose of this study is to investigate the effect of parents' socioeconomic status, communication between parents and adolescents, and adolescents self-esteem on adolescents emotional autonomy and behavioral autonomy. The data were collected from 367 middle and high school students. The significant results were as follows. First, emotional autonomy was influenced by dysfunctional communication between the father and adolescent and open communication between the mother and adolescent after controlling for the socioeconomic status of the parents in step 2. Second, behavioral autonomy was affected by the socioeconomic status of the parents in step 1, and dysfunctional communication between the mother and adolescent and self-esteem were the meaningful predictors of behavioral autonomy after controlling for the socioeconomic status of the parents in step 2. Finally, the meanings and limitations of this research and implications for counseling strategies were discussed.

The purpose of this study was to analyze the characteristics reflected in the 2015 revised home economics curriculum for the key competencies presented in the OECD education 2030 project. The results indicate that first, in general, about 46.5% of the competencies could be classified into the skill, attitude and value category; 17% into the learning concept framework category; 24.2% into the competency development cycle category; and 12.5% into the complex competency category. Overall, the competencies of the OECD learning framework are found to be reflected primarily in the achievement standards(59%), followed by characteristics(16.1%), teaching-learning and assessments orientation(9.4%), content system(8%), and goals(7.6%). Second, the key competencies were reflected in the middle school curriculum, more often in the descending order of action, problem-solving, communication, respect, creative thinking, conflict resolution, empathy, critical thinking, self-regulation, and student agency. In the high school curriculum, the competencies were reflected more often in the descending order of action, empathy, problem-solving, anticipation, global competence, self-regulation, student agency, literacy for sustainable development, reflection, and critical thinking. Third, the heat map shows that the competencies corresponding to the third and fourth levels are most frequently reflected in the curriculum. Therefore, it is advisable to develop effective plans to execute and support the reflection of key competencies in the curriculum. Through this study, home economics educators are expected to understand the inter-connectivity between the key competencies emphasized by the OECD learning framework and the competencies of home economics as a practical subject, and to scrutinize how to help individual students develop their overall competencies and be prepared for the future.

This study evaluated the perception, school stress, psychological factors, and association of students in middle and high school groups in terms of their BMI (Body Mass Index). The '2010 Korea Youth Health Survey 'was used to study data 7187 people. The subjects were classified into the underweight group (BMI < 20), normal group (BMI 20 - 24), overweight group (BMI of 25-29), and obese group (BMI of 30 or higher). The subjects found to have experienced smoking were as follows: underweight BMI group (17.2%), normal weight group (18.4%), overweight group (21.8%), and obese group (25.8%) (p=0.016). The level of satisfaction was as follows: $14.24{\pm}3.15$ for the normal weight group, $13.67{\pm}3.13$ for the overweight, and $12.84{\pm}3.72$ in the obese group. The normal-weight group had a higher level of satisfaction (p=0.005). Underweight, normal, overweight, and obese BMI group were at school for an average of $33.57{\pm}5.76$, $33.45{\pm}5.50$, $33.12{\pm}5.34$, and $32.21{\pm}7.43$ hours per week, respectively (p=0.044). Therefore, the development of social misfit youths needs to be managed properly and effectively to improve their physical and mental health. Industry, academia and government need to collaborate with programs to achieve this aim.
