Due to the rapid development of multimedia appliances, the increasing amount of multimedia data enforces the development of automatic video analysis techniques. In this paper, a method of ToC generation is proposed for educational video contents. The proposed method consists of two parts: scene segmentation followed by scene annotation. First, video sequence is divided into scenes by the proposed scene segmentation algorithm utilizing the characteristics of educational video. Then each shot in the scene is annotated in terms of scene type, existence of enclosed caption and main speaker of the shot. The ToC generated by the proposed method represents the structure of a video by the hierarchy of scenes and shots and gives description of each scene and shot by extracted features. Hence the generated ToC can help users to perceive the content of a video at a glance and. to access a desired position of a video easily. Also, the generated ToC automatically by the system can be further edited manually for the refinement to effectively reduce the required time achieving more detailed description of the video content. The experimental result showed that the proposed method can generate ToC for educational video with high accuracy.

The purpose of this study is to explore non-major students' perception and experiences in college software education. For this, we analyzed the reflection journals of 36 non-major students in D University based on the Consensual Qualitative Research(CQR). As a result, there was not general core concept to all students nor a typical core concept that appeared to more than 50% students. However, various variable core concepts could be derived. Overall, 57 variable concepts were derived from experience in SW education and 7 variable concepts for perception of SW education. Based on this result, we found many of non-major students feel difficulty from unfamiliarity to SW education. Also, many students have satisfaction in their perception to SW education about personalized learning that their professor provided in the class. Lastly, we conclude that a methodology for SW education needs to have a careful operation strategy and interactive design. Although this study has not been able to elucidate general core concepts that appear to all learners, it has significant implication in terms of providing various implicit core concepts and suggestions for effective software education for non-major students.

The mathematical ability is an essential element for achieving professional competencies and for enhancing application ability in a vocational world and exploring its experiences. In this aspect, for vocational high school students, it is an important and urgent issue to develop remedial learning programs for developing mathematical basic and application ability. In particular, the program is developed based on the individual achievement level, focused on a mathematical basic ability to be applied efficiently in a vocational world. Because of this reason, in this study, the program is comprised of two phases; one is diagnosis test and the other is remedial teaching and learning materials. Then, diagnosis test includes three test; I) level testing evaluation for selecting the subject of remedial learning, ii) pre-test for deciding on which area and level of the materials when students begin to study, and iii) post-test for confirming the learning status is satisfied and the possibility of next step(level) or the other area of the materials. To accomplish this, this study tried to devise an efficient remedial learning system. Based on the system, this study developed remedial learning programs on the four areas of number and quantity, change and relation, uncertain thing, and figure and shape in the middle school level. In particular, this program is comprised of two types of knowledge. One is K-knowledge which is an essential knowledge to achieve a basic mathematical ability. The other is C-knowledge which is the advanced knowledge required to apply efficiently in a vocational world. This paper deals with the content mentioned above, but examples of the materials is shown focused on the area of change and relation.

This qualitative analysis was conducted to analyze the effects of teeth and eating foods in the elderly on their subjective happiness based on a focus-group interview (FGI). The study subjects were 10 people over 65 years old who visited a social welfare center in D City and agreed to participate in the study. One group consisted of five members and FGIs were performed for about 40 minutes per group. Based on the study results, five topics were evaluated, status of teeth, methods of dental health control, inconvenience within mouth, eating foods, and eating foods and subjective happiness. The study subjects answered that they felt distressed and annoyed if they could only see, but not eat favorite foods and that this made them feel old. One respondent even mentioned it made them want to stop living. Based on the results of this study, it is necessary to develop customized dental health control programs by age, gender, income level, education level, and health status, and to build the specialists.

Purpose: This study was conducted to assess the effects of a personalized nutritional intervention program on food security and health and nutritional status of elderly people in the city of Seoul. Methods: A total of 372 elderly adults aged 65 years or above who resided in Seoul were enrolled in this study. Personalized supplementary food supply and nutritional education based on chronic disease status, disability and cooking ability were implemented for 4 months. To evaluate the effectiveness of the program, nutrient intake, food security status, anemia status, chronic disease management, and frailty status, and prevalence of malnutrition (Mini Nutritional Assessment) were examined. Results: After the program, all subjects displayed significantly increased nutrient intake. Before the intervention, all subjects were in a state of food insecurity; however, after the intervention, 37.1% of the subjects were food secure. Moreover, the rates of being at risk of malnutrition and malnutrition in subjects were decreased and instead rate of those who improved to normal increased to 29.8% from 0% of normal rate before the prevention. The rate of subjects without anemia increased from 18.7% to 28.5% after the intervention. In addition, the rate of subjects with intensive or periodic management of chronic diseases decreased, while those with occasional management of chronic diseases increased from 0% to 4.6%. Furthermore, the rates of being at risk of frailty and frailty were decreased and the normal rate increased from 0% to 9.7% instead. Age group-based analysis showed that elderly people over 80 years showed less improvement in the management of the chronic disease status and the frailty status. Conclusion: Personalized supplementary food supplies and nutritional education improved not only the nutritional status but also disease status in vulnerable older adults, and the effects were more significant in adults aged less than 80 years.

This study aimed to track changes in students' perception about schools over time, to analyze how participation in the Education Welfare Priority Support Project(hereafter "the Project") explains the changes, and to determine how the results of changes affect students' learning engagement, self-confidence, and peer relationship. Data were collected from 103 schools nation-wide(51 elementary and 52 middle schools) from 2015, 2016 and 2017 from 820, 911, and 837 students, respectively. The data were analyzed by applying a latent growth model with two stages: unconditional and conditional. The findings are that first, the perception about schools by the students who participated in the Project increased over time; and second, that the improvement of students' perception of schools has a positive influence on their learning engagement, self-confidence, and peer relationship. In the future, it was suggested that programs aimed at improving positive perception about schools should be provided to all students led by teachers, and a customized integrated support program should be arranged to students in need of intensive support by the educational welfare specialists.

Purpose: Despite the well-known public health benefits of vaccination, increasing public concern about the safety of childhood vaccinations has led some parents to refuse or hesitate having their children immunized. The purpose of this study was to identify the subjectivity of parents toward refusal of childhood vaccination. Methods: Q-methodology, in which subjective viewpoints are explored and analyzed using a combination of quantitative and qualitative techniques, was used. Thirty-five participants were asked to rank 42 statements on diverse issues of childhood vaccination according to a continuous 9-point scale ranging from -4 for strongly disagree to +4 for strongly agree. Collected data was analyzed using the PC-QUANAL program. Results: The results revealed three discrete groups of parents in the refusal of children's immunization: type I, distrust; type II, concern about side effects, and type III, belief that vaccinations are unnecessary. Conclusion: Special nurse counselors who can provide correct information about vaccination based on the three types should be part of the government policy. Customized education programs to shift viewpoints should be also redeveloped according to the results in this study.

The objectives of this study were to explore food-related lifestyle segments of the older consumers, to identify its socio-demographic characteristics, and to investigate the differences in variables regarding health beliefs. A survey was conducted of adults 55 years of age and older living in Seoul, South Korea from March 28 to April 10, 2007. Out of the 500 distributed questionnaires, 361 were retained for final analysis: a response rate of 72.2%. As a result of cluster analysis, five consumer segments were identified; health-managing group, diet-unconcerned group, convenience-oriented group, taste-oriented group, unpracticed group. Significant differences were found among the five segments in terms of socio-demographic characteristics and variables regarding health beliefs (i.e., perceived self-efficacy, perceived barriers, perceived benefits). In the health-managing group and taste-oriented group, mean scores of perceived self-efficacy (p<0.001) and perceived benefits (p<0.001) were significantly higher than other groups. However, in the diet-unconcerned group and convenience-oriented group, the mean scores of perceived barriers (p<0.01) were significantly high. This study shows that foodservice operators targeting the older consumers should consider characteristics of each segment to develop a customized program.
