As sensor technologies and image processing technologies make collecting information on users' behavior easy, many researchers have examined automatic emotion recognition based on facial expressions, body expressions, and tone of voice, among others. Specifically, many studies have used normal cameras in the multimodal case using facial and body expressions. Thus, previous studies used a limited number of information because normal cameras generally produce only two-dimensional images. In the present research, we propose an artificial neural network-based model using a high-definition webcam and Kinect to recognize users' emotions from facial and bodily expressions when watching a movie trailer. We validate the proposed model in a naturally occurring field environment rather than in an artificially controlled laboratory environment. The result of this research will be helpful in the wide use of emotion recognition models in advertisements, exhibitions, and interactive shows.

본 연구의 목적은 영어 듣기와 읽기 수업을 위한 블렌디드 러닝에서 학생들의 학습행태를 파악함으로써 그 교육적 효과를 진단하는 사례연구이다. 연구대상은 Academic English Listening and Reading 과목을 수강했던 75명의 학생이며 연구도구는 2차례 실시한 설문이다. 연구 결과 영어듣기를 위한 온라인 수업에서 학생들은 스크립트를 보거나 교수 동영상 강의를 보고 듣기 퀴즈를 풀고 있었으며, 예습의 역할을 하고 있는 스크립트 요약 과제의 경우 번역본을 찾아보는 등의 바람직하지 않은 학습행태를 형성했음을 알 수 있었다. 반면 오프라인 수업에서 학생들은 조별활동에 성실하게 참여했으며 교수 해설 강의에 잘 집중하는 모습을 보여주었다. 따라서 학생들의 바람직하지 않은 온라인 수업의 학습행태를 감안할 때 이 블렌디드 러닝은 면대면 수업에 비하여 교육적 효과가 떨어진다고 판단되었다. 이에 이러한 부정적인 학습행태를 개선하기 위한 해결책들을 논의하였다.

영화 관객들은 영화를 선택하기 위해 정보를 수집하는 등의 과정에서 추가적인 비용을 지불할 수 있다. 본 논문은 이러한 비용을 거래비용의 관점에서 접근하여 영화 소비행위를 분석하였다. 분석을 위해 '2015 영화소비자조사'를 사용하여 영화 정보와 개인의 인구사회학적 특성을 독립변수로, 관람편수와 관람빈도를 종속변수로 삼아 회귀분석과 다항 로지스틱 회귀 분석을 실시하였다. 분석 결과, '감독', '온라인 평가' 등의 요소를 고려하는 소비자일수록 영화 소비가 활발한 것으로 나타났고, 관람 빈도별 분석에서는 저 고 관람자별로 영화를 선택할 때 고려하는 유의미한 정보가 다르게 나타났다. 이를 통해 개인이 보유한 문화자본과 취향 그리고 영화 정보를 인식하는 정도에 따라 영화 소비가 달라질 수도 있음을 알 수 있었다. 기존 연구들이 주로 영화의 흥행 결정 요인을 분석했다면 본 연구는 소비자의 입장에서 개별 영화 정보를 이용하는 것을 거래비용 관점에서 개인의 취향의 유무, 형성의 정도에 따라 차이가 있다는 것을 실증적으로 분석했다는데 의의가 있다. 상기의 결과를 바탕으로 거래비용이 영화소비에 영향을 미치고 일정 정도의 소비를 통해 취향이 형성되면 거래비용이 낮아져 소비가 늘어나는 순환적 구조라는 것을 추정할 수 있었다. 따라서 제작사는 소비자가 영화 관람에 필요한 거래비용을 낮출 수 있도록 영화 정보를 적절하게 활용하는 마케팅 전략을 수립하고 집행할 필요가 있다.

The necessity of school health promoting projects is well known to many researchers, however, there is a lack of research on the development of strategies for school health programs and the evaluation of the effectiveness of the programs. The results of our previous study in 1996 identified poor eyesight as one of the several health problems among elementary school children in urban areas. The main objective of this study is to develop, implement, and evaluate vision care for elementary school children. The research method utilized a quasi experimental design using non-equivalent group, pre-post comparison. The sample consisted of all second grade children in two elementary schools in Kyung-giProvince. In order to prevent a contamination effect of the vision care program, one school was selected as a control and the other school was selected as a treatment group. The experimental school had 467 children and the control school had 402 children. The visual acuity of children in both group was measured and a survey questionnaire was sent out to parents on the knowledge, attitude, and behavior related to vision care before the program was implemented. The children of the experimental school received the following programs; separate education on proper nutrition and care of eyesight for children and parents, daily eye exercises using video tape, and an essay and poster contest on healthy eyesight. The eye exercise program lasted from March, 1997 to November, 1997. On November, 1997, visual acuity was measured again from children in both schools. The data was analyzed by using SAS statistical package. The results indicate that the children in the experimental group had significantly (p〈0.001) better eyesight than the children in the control group. Also, some of the behavior highly related to the poor eyesight are poor maternal eyesight and watching TV from a short distance. In conclusion, one of the significance of this project is that the vision care program was developed after the need assessment. It will be encouraged in the future that more school health program should be developed after a need assessment. Also, inclusion of family members was important in health promoting projects within a school setting since healthy behavior needs to be reinforced at horne as well as at school.

This study was conducted to investigate the differences in food habits, eating behaviors and food frequency by gender and regions in upper grade elementary school children in Korea. Subjects of this study were 1,211 children, 645 boys and 566 girls, attending 6 elementary schools (4th, 5th and 6th graders). 389 children lived in Seoul and 822 children lived in other regions. Mean height, weight and BMI of subjects were 142.4 cm, 38.7 kg and $18.8\;kg/m^2$ respectively. 70.5% of the subjects had breakfast every day and 12.4% of the subjects skipped breakfast. There were significant differences between boys and girls in causes of skipping breakfast, overeating, meal volume, and duration of meals. Girls showed more desirable eating behavior than boys (p < 0.001). Scores for specific eating behaviors such as unbalanced diet and intake of meats and vegetables were better in girls (p < 0.001), and boys ate meals faster than girls (p > 0.001). There were significant differences between Seoul and other regions in eating behavior. Eating behavior scores of children in other regions were higher than in Seoul (p < 0.01). Children in Seoul had a higher frequency of watching television with meals. Frequency of fruits (p < 0.001), milk products (p < 0.01), and meats (p < 0.05) of children in Seoul were higher than other regions. Otherwise the frequency of simple sugar products of children in other regions was higher than Seoul (p < 0.001). Frequency of green vegetables was higher for girls than boys, and frequency of fast foods was higher for boys than girls. These results showed that in nutrition education programs designed to improve the nutritional health of elementary school children, we need to focus more on differences in the children's food habits and eating behaviors by gender and regions. In consideration of these differences, such educational programs need to have a different emphasis for each gender and regions to serve its specific needs.

BACKGROUND/OBJECTIVES: Dietary behavior and life stress in adolescence is related to growth rate and learning ability. This study was conducted to identify the relations between dietary habits, dietary attitude nutritional knowledge and life stress among high school girls in Korea and China. SUBJECTS/METHODS: The subjects of this study were 221 high school girls in Korea and 227 high school girls in China. The questionnaire were about dietary habits, dietary attitude, nutritional knowledge and life stress. RESULTS: The dietary habits of chinese girls were healthier than those of Korean girls with a significant difference (P < .001). There was no significant difference in dietary attitude between Korean girls and Chinese girls. Korean girls had more nutritional knowledge than Chinese girls with a significant difference (P < .001). Korean girls did less physical exercise but spent more time watching TV and using PCs, compared to Chinese girls. Korean girls' degree of confidence in nutrition information that they had learned and their performance in their real lives were low. Also, they had a low level of awareness of the need for nutritional education. There was no significant difference in life stress between the two groups. Dietary habits had a significantly negative correlation with life stress in both Korean and Chinese girls (P < .01, P < .001). As for Chinese students, dietary attitude had a negative correlation with life stress with a significant difference (P < .05). As for Korean girls, nutritional knowledge had a negative correlation with life stress with a significant difference (P < .05), which means as life stress was less, dietary habits were better. CONCLUSIONS: This study shows that effective nutrition education programs should include components that encourage application of learned nutrition information to real life, increase physical exercise and reduce life stress.

In order to provide data of effective health education for practice of preventive health behavior for visual acuity care. The authors investgated the actual acuity and health behavior for visual acuity care. The subjects of this study were 2250 students in high school. The data were collected by questionnaire developed for the purpose of this study which has been made through references and student's health record. The results were as follows, 1) As students move up to grade, the number of students with decreased visual acuity had a tendency to increase. In cases with decreased visual acuity below 0.2 in one or both eye, the number of cases was increased in accordance with moving up to grade, especially visual acuity of right eye was more decreased than that of left eye. 2) As to proportion of the group with decreased visual acuity among the total students, among 2250 students, students with decreased visual acuity was 35.6%(800 students). According to school type, in academic school, frequency of students with decreased visual acuity in day school was higher then that in night school. In commercial school, the frequency of students who had decreased visual acuity in night school were higher than that of students in day school. 3) As to variables influencing the decreased visual activity, there was a significant different between groups with normal visual acuity and groups with subnormal in terms of awareness of visual acuity by themself, parent's visual acuity, unbalanced eating habit, distance from television, or books, posture in watching television, posture in reading, awareness of illumination in classroom. 4) As to practice of protective and preventive health behavior for visual acuity care, In group with normal visual acuity. There was good practice such as proper eating habit, proper studying habit, and health habit in its descending order, but proper illumination and regular eye test were practiced poorly. In group with subnormal visual acuity, one of the vest practice in visual acuity care was an effort to prevent eye strain. Other good practice involve tasking regular eye test, maintaining proper studing habit, in its descending order.

This study examined the state of health and weight maintenance according to the body mass index (BMI) , and explored demographic variables, diet variables, the degree of stress etc. The results presented were based on data collected from 428 women who are mothers of the middle school children in Jeongeup city. Using SPSS WIN (Ver 9.0) , the frequency, percentage, mean, standard deviation, chi-square, ANOVA, and correlation analysis were provided. The mean of BMI for the subjects was 22.6, the ratio of obese women (BMI $\geq$ 25) was 22.9%. The frequency of the reported circulation or respiratory related diseases was greater in the obese group compared to the normal weight ($20 \leq BMI \leq 25$) or the lean (BMI < 20) groups. The obese group had less awareness of obesity. Those who regard themselves obese had lower rates of satisfaction with their body shape and higher rates of interest in weight control. Approximately 65% of the subjects attempted weight reduction more than once. Subjects who were obese had the most undesirable dietary behavior. In particular, this group had the higher rates of rushed meals, overeating, meals while watching TV or newspapers, and snacking, and eating out. In analyzing the correlation of variables influencing obesity, there were positive correlations between obesity and overeating, obesity and the degree of stress. Correlations between obesity and satisfaction for life found to be negative. Moreover, stress had a positive correlation with obesity and overeating, and showed negative correlation with eating behavior. Consequently, stress seemed to induce undesirable eating behaviors and increase obesity. Of the demographic background variables, subjects who were obese tended to be older, had lower levels of education, higher rates of employment, longer period of marriage, the higher number of children, preschool children or children preparing for highschool or college, lower satisfaction with children and household life.
