The creative thinking and emotional trainings are very important educational issues in the knowledge-information-based future society. Recently STEAM education is suggested as one of the educational solutions to prepare the future society. The aims of this study are to develop STEAM teaching-learning program and analyze its effects on the creativity and emotional intelligence of science-gifted and general students in elementary school. Four different subject matters based on the 2007-revised curriculum were selected to construct the brain-based STEAM teaching-learning program consisting of 12 class hours. The program was applied to 50 elementary general students and 19 science-gifted elementary students. The findings of this research are as follows. The brain-based STEAM programs is effective to improve the creativity and emotional intelligence of science-gifted and general elementary students after class. The creativity of two groups was not statistically different before the class. However after class, the creativity of gifted-science students is significantly higher than that of general students. The emotional intelligence of gifted-science students was higher than that of general students before the class. Therefore in oder to analyze the different effects of the program on two groups in emotional intelligence, the test results of both group of students were analyzed by ANCOVA after class. This analysis also showed that the program is more effective in gifted-science students to improve the emotional intelligence compared to general students.

The purpose of this study was to analyze the relations among the three factors: 1) characteristics of family, 2) nutrient intake status and 3) academic achievements. The subjects in this study were 7,698 boys and girls attending primary, middle and high schools in South Korea. The questionnaire was made and distributed to the student to answer the questions about family background and food intake status. Food intake frequency method was used to examine nutrient intake status. Academic achievement results of last semester were taken from students school records. Followings are the results of the study:1. Most of the mean nutrient intakes were above the Korean recommended dietary allowances. However, calcium, iron, and vitamin A intakes were below the Korean recommended dietary allowances. Therefore, it is recommended to increase the intake of these nutrients in these students to meet the RDA.2. Total amounts of food intake were decreasing in higher grades and food intake of boys was higher than that of girls. 3. Educational period of parents and economic status of family had grades influences on student's academic achievement and nutritional status. The students with parents of higher education and higher economic status had better academic achievement and balanced nutritional status. 4. When students were divided into three groups with respect to the percentage of recommended nutrient intake, the group with nutrient intake of 75-125% of RDA achieved better academic achievement than other groups. In conclusion, educational length and economic status of parents and optimal intake of nutrients (75-125% of RDA)by students significantly affected academic achievements of the students.

The purpose of the study is to examine the demographic characteristics and socio-psychological factors affecting willingness to take health foods among elderly, which is to get the basic materials of educational program for helping their desirable intake of healthy food. The data were collected from 1,032 elderly subjects and analyzed by SPSS Windows Version 12.0. About forty-one percent of the respondents were taking health foods in the period of survey. The main reason of taking health foods was to maintain and improve their health. The elderly subjects were classified into three groups: (1) a group having willingness to take healthy food, (2) a group having unwillingness to take healthy food, and (3) a group having a wait-and-see attitude. According to the results of chi-square and analysis of one-way variance, there were significant differences among three groups in the variables of 'sex', 'age', 'educational level', 'marriage status', 'monthly allowance', 'eating habit', 'concerns about health', 'self -evaluation of health condition', 'self-evaluation of health condition compared to the same age', 'concerns about health foods', and 'awareness of health foods'. In addition, the result of multinomial logistic regression analysis showed that the factors affecting willingness to take health foods in the future are 'age', 'concerns about health', 'self-evaluation of health condition compared to the same age', 'awareness of health foods', and 'intake of health foods in the period of survey'.

Purpose: This study purposed to examine the effect on health educational curriculum by grasping knowledge, attitude, and the extent of practicing it after giving a health education curriculum for 17 hours. Methods: This study was a non-equivalent control group pretest-posttest conducted with the first-graders enrolled in a middle school students in Gyeonggi Province. A total of 191 completed questionnaires from the test group and the control group each were used for the final analysis. The survey period was from March 5 to March 13, 2009 before the education was given from July 20 to July 25, 2009 after the education. A total of 38 questions were used to measure knowledge and a total of 39 questions were used to measure attitude and practice. This study used $x^2$ test, ANOVA, and t-test, Paired t-test. Results: After the health education curriculum was given, the test group s knowledge of health education was found higher than that of the control group. There was a difference between two groups, but considering the perfect score of 38, the knowledge scores of both groups were not high. With regard to each group s attitude and practice of health education, the study compared the scores obtained before and after the education and found that the test group had higher scores than the control group, showing a significant difference. Conclusion: In order for a health education curriculum to successfully have favorable influence on the health of teenagers, the curriculum should be offered for a more extended period of time than 17 hours and as a compulsory course, not a selective one, so that all the students can develop their health management capabilities.

An individual's food-related personal traits play an important role in influencing personal food choice and habits. According to culture, their influence can manifest differently. To ascertain personal traits about food, FNS (food neophobia scale) and FIS (food involvement scale) were employed in recent studies. This study aimed to understand the food culture and food choices of East-South Asians who live or stay in Korea through comparison of FNS and FIS. Eighty Koreans and 233 East-south Asians (Indonesians, Filipinos, Malaysians, Vietnamese, Thai, Singaporeans, and Bangladeshi) completed a questionnaire to measure FNS (10 questions), FIS (12 questions), and sociodemographic conditions (9 questions). ANOVA was conducted to ascertain FNS and FIS between the groups, and regression analysis was carried out to determine which sociodemographic factors had an effect. The items were analyzed to determine the differences according to gender, age, marital status, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. FNS showed significant differences between the groups with regard to sociodemographic characteristics, except gender, age, and marital status, whereas FIS showed significant differences in gender, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. The results of the regression analysis suggest that nationality strongly affected FNS and FIS, and FIS was also affected by gender.

This study verified the effects that a programming-based TPACK education program, through design-based research on TPACK, had on pre-service teachers. The research subjects were pre-service teachers attending teacher training at a university in Korea, and 129 control groups and 126 experimental groups were recruited through lectures. The treatment used a TPACK educational program developed in a design-based study (Kim & Lee, 2019). A TPACK test tool developed by Park and Kang (2014) was used. The test results were analyzed via independent sample t-test and paired sample t-test. The results show that the programming-based TPACK education program (first cycle) was only effective in improving TPK and TPACK, but an effective educational program was developed to improve PCK, TCK, TK (second cycle), PK (third cycle), and CK (final cycle). This design-based research therefore confirmed the development of a programming-based TPACK education program that was effective for improving the TPACK of pre-service teachers.

Objectives: This study identified how personal characteristics, healthy behavior and social capital might influence on physical activity of adults. Methods: This study used data from the health survey of a city of Korea. We surveyed 1,000 adults sampled by stratified sampling methods from 67,889 households. Outcome variable was the stage of physical activity which was broken into 5 categories. Sociodemographic factors, healthy behavior, self-rated health status and social capital were used as control variables. Sociodemographic factors included age, sex, educational status, economic status measured by deprivation score, residential period within survey city. Social capital was measured by Integrated Questionnaire for the Measurement of Social Capital (SC-IQ). This study used chi-square test and ordered logistic regression models to examine the associations between independent variables and physical activity. Variables were added to the regression model in three groups using a hierarchical approach. Results: Physical activity was significantly more likely to become active if they have higher educational status, healthier behavior. Among the six dimensions of SC-IQ, only "groups and networks" that is structural dimensions of social capital and "trust and solidarity" that is cognitive dimensions of social capital were significantly related to physical activity of adults. We found that a person having higher density of membership and having larger size of networks showed the high possibility of active physical activity. A person having high solidarity was significantly associated with physical activity, but general trust was inversely related to physical activity. Output dimensions of social capital did not show significant relationship to physical activity. Conclusion: We found that social capital is useful concept to explain health behaviors like physical activity. However we must consider social, cultural and political context of the study to evaluate the effect of social capital to health status and health determinants and to capture the exact meaning of relationship between them. We suggest further researches to refine the concept of social capital and to explain the relationship of social capital to diverse health determinants.

PBL is a process and an effective educational tool that empower the student to be an active participant and emphasize a clinical context for learning, developing skills in working with a group, and encouraging self-directed study. The purpose of this study was to develop the PBL module based on lung cancer case, and to evaluate after implementation. The data on lung cancer patients at C university hospital in K city were collected from interviews and nursing records in June, 1999. A PBL module was developed including situation scenarios, timetable and tutor guide. PBL course was conducted at C university for short term period (3 days) in August, 2000. Fourteen nursing students at C college were participated in this study and they were divided into two small groups. I explained them about the PBL course through a preparatory meeting. At a stage of implementation, two groups went through the same process consisting of seven steps with group meetings and self-directed study. Their performances of identifying, stating problems and presenting referred resources were evaluated and supervised by researcher. The PBL course was evaluated by them with questionnaire and essay. Most students responded positively about PBL course and preferred the tutors in a supportive attitude. However, 3 days for PBL course seemed not enough for maximal educational benefits, and many possible problems were discussed. It is necessary for nursing educators to accumulate lots of knowledge and skills regarding creating good working problems and implementing and evaluating diverse PBL tutorials to test the feasibility changing to PBL curriculum.

The objective of this study was to characterize factors influencing genetic improvement of dairy cattle for milk production at farm level. Data were accumulated from 305-day milk yields and pedigree information from 1,921 first-lactation dairy cows that calved from 1990 to 2007 on 161 farms in Central Thailand. Variance components were estimated using average information restricted maximum likelihood procedures. Animal breeding values were predicted by an animal model that contained herd-year-season, calving age, and regression additive genetic group as fixed effects, and cow and residual as random effects. Estimated breeding values from cows that calved in a particular month were used to estimate genetic trends for each individual farm. Within-farm genetic trends (b, regression coefficient of farm milk production per month) were used to classify farms into 3 groups: i) farms with negative genetic trend (b<-0.5 kg/mo), ii) farms with no genetic trend (-0.5 kg/$mo{\leq}b{\leq}0.5$ kg/mo), and iii) farms with positive genetic trend (b>0.5 kg/mo). Questionnaires were used to gather information from individual farmers on educational background, herd characteristics, farm management, decision making practices, and opinion on dairy farming. Farmer's responses to the questionnaire were used to test the association between these factors and farm groups using Fisher's exact test. Estimated genetic trend for the complete population was $0.29{\pm}1.02$ kg/year for cows. At farm level, most farms (40%) had positive genetic trend ($0.63{\pm}4.67$ to $230.79{\pm}166.63$ kg/mo) followed by farms with negative genetic trend (35%; $-173.68{\pm}39.63$ to $-0.62{\pm}2.57$ kg/mo) and those with no genetic trend (25%; $-0.52{\pm}3.52$ to $0.55{\pm}2.68$ kg/mo). Except for educational background (p<0.05), all other factors were not significantly associated with farm group.
