The study surveyed 1,127 mothers whose children aged 3 to 5 went to 25 randomly selected kindergartens, which were located in Busan Metropolitan City and the adjacent Gimhae City, and analyzed the preventive health behaviors on their children and the condition of home health education on their children. As the compulsory kindergarten education will e to be implemented within 4 years, this study aimed to draw up the rudimentary material for health education at kindergartens. The study results are summed up as follows: 1. Mothers' awareness of health-related attitude and behavioral level for their children at kindergarten: 1) The general health condition of the children, which mothers are aware of, was that they were healthy on the whole. As their children becomes older, the income level of the parents is lower, and mothers have lower level of educational standard, the health condition of the children was found a little lower. 2) In terms of mothers' recognition of the practice level of preventive health behaviors, the items such as going to bed regularly, washing hands and feet well, and having meals regularly were high in the practice level, while exercise and tooth-brushing were not practiced well. 2. The condition of mothers' health education of their children: 1) It was found that washing hands and feet, restriction of overeating and preference for specific kinds of food, guidance on regular sleep and regular meal were practiced well among items of home health education targeting kindergarten children. 2) Mothers have obtained information on family health from printed matter such as newspaper or magazine rather than the visual media. 3) From the cross analysis of mothers' health education on children and children's health behaviors, as the standard of education of mothers was higher, so was the level of preventive health behaviors of children. 3. From the result of multi regression analysis of the factors influencing the preventive hygiene of kindergarten children, it was found that as the home health education level was higher, so was the health behavior of children. On the other hand, as the mothers were older, the health behavior of children became lower.

Research into scientific inquiry methods indicates that providing various types of inquiry methods can enhance students' science loaming in terms of providing students with actual science in various ways' more so than exposure to one type of inquiry method. This article develops a framework for an analysis of scientific inquiry types based on the nature of scientific enterprise. We selected three types of scientific inquiry: these were minds-on activities, hands-on activities, and experimenting. Elementary science textbooks in the 7th national science curriculum were analysed according to the following subject areas; earth science, physics, biology, and chemistry. A total of 61 teaching units from 3rd through 6th grade science textbooks were investigated. The frequencies of each type of scientific inquiry method were slightly different among four science subject areas. The most frequent type which appeared in physics and chemistry was the hands-on type, while the minds-on activity type was the most frequent type which appeared in earth science and biology.

This study analyzed the influencing factors of learning engagement and teaching presence in online programming practice classes. The subjects of this study were students enrolled in an industrial specialized high school, who practiced creating Arduino circuits and programming using a web-based virtual practice tool called Tinkercad. This research adopted a tool that can measure task value, learning flow, learning engagement, and teaching presence. Based on this analysis, learning flow had a mediating effect between task value and online learning engagement, as well as between task value and teaching presence. Increasing learning engagement in online classes requires sensitizing the learners about task value, using hands-on platforms available online, and expanding interaction with instructors to increase learning flow of students. Furthermore, using virtual hands-on tools in online programming classes is relevant in increasing learning engagement. Future research tasks include: confirming the effectiveness of online learning engagement and teaching presence through pre- and post-tests, and conducting research on various practical subjects.

This study evaluated effects of food additive nutrition education on food additives-related knowledge, subjective awareness, and perception and dietary behaviors of food label use and processed-food intake. The study subjects were 5th grade students attending an elementary school in Seoul. A total of 101 subjects were assigned to either education (N = 50) or control (N = 51) group, and 3 food additive nutrition education classes were implemented to the education group. Self-administered questionnaires were collected from all the participants twice, a week before and after the nutrition education to compare the changes between two groups. The food additives-related knowledge and subjective awareness significantly improved in the education group compared to the control group. The changes in perceived harmfulness and perceived necessity for taste were also detected significantly different between the two groups, with more positive changes in the education group. Dietary behaviors of checking food labels and trying to purchase processed-foods with less food additives improved in the education group at a significant level in comparison with the control group. Additionally changes in intake frequency of several processed-food items were significantly different between the groups, again in a more positive direction in the education group. The study findings showed short-term food-additive nutrition education including hands-on activities could positively modify elementary school children's food additives-related knowledge, perception, and certain dietary behaviors, stressing better settlement of in-class nutrition education within an elementary school's education curriculum.

In 2020, the COVID-19 pandemic has brought dramatic changes in the field of engineering education. Contrary to the traditional engineering education emphasis on content-oriented, design-based, hands-on, experimental, and field experience, most of engineering classes in 2020 had to be undertaken remotely online. However, it has not been explored how professors and students perceive about such a shift in engineering education. The aim of the current study was to investigate the perceptions of professors and students on online classes in engineering colleges during spring Semester 2020. Questionnaire data were collected from 100 professors and 4,152 students in the college of engineering. The results of this study were as following: Students were less satisfied with the online classes than professors. The online lecture method that students were most satisfied with was the recorded lecture. This is likely due to the fact that the recorded lectures can be repeated multiple times anytime, anywhere. Moreover, the experimental classes, which conventionally has more of an emphasis on the hands-on experience, also had to be conducted remotely, showing even lower satisfaction among students. Most of professors reported that the average hours they spent on preparing for online lecture increased compared to face-to-face class. Both professors and students preferred in-person exam as a desirable method of end-of-semester assessment for grading. The results of the current study have important implications for the improvement of online course environments. It is important for professors to design a structured class suitable for online education and understand the challenges students encounter during online classes. Also, professors should communicate more openly about their expectations and rubrics for class goals and assignments. Schools also needs to make effort to provide the support for the internet environment of students.

A study was conducted in order to develope HACCP model in school lunch in Korea. Results: 1. Of 22 menus 4(18%) were non heating processes (#1), 2(9%) were food handling by using hands (#2), and 16(73%) were heating processes (#3). Of 279 menus 36(12.9%) belong to process #1, 8(2.9%) to process #2, and 235(84%) to process #3. 2. The critical control points for process #1 were contamination by hands of food handlers, and unsanitary food preparation habits of food handlers. Those for process #2 were improper heating temperature, contaminations by food handlers' hands, and unsanitary food handling habits, and cross contamination by unclean utensils and equipment. 3. Management criteria for the CCPs were conditions of food storage, refrigeration, freezing, food cooking temperature, personal hygiene, washing and sanitization of utensils and equipment. 4. Monitoring criteria for CCPs were observation, temperature checking, inspection of utensils and equipment, and practice of good personal hygiene. 5. Corrective actions were refusal of unsafe products, correction of improper temperature, proper cleaning and sanitization, and proper reheating time and temperature.
