A study on food sanitation in school textbooks was performed for 7 months from October 1, 1992 through may 31, 1993. A total of 243 textbooks (77 from elementary school level, 52 from junior high school level and 114 from senior high school level) were reviewed and analyzed. This study was performed in order to develop better method for teaching the subjet of food sanitation to students effectively. The results are as follows: 1) A total number of pages of textbooks dealing with food sanitation were 48 pages (0.53%) in elementary level textbooks, 38.05 pages (0.31%) in junior high school level and 105.05 pages (0.34%) in senior high school level. 2) 104.05 pages were allocated for the subject of food storage, 33 pages for insect and rodent control, 32 pages for food poisoning, 15 pages for food contamination and 7 pages for kitchen hygiene. 3) Of the four categories of textbooks, the numbr of pages dealing with food sanitation were 145 in home economics, 31 in physical education, 12 in social studies and 3.0 in science. 4) Home economics and physical education textbooks allocated many pages in dealing with food sanitation. Home economics textbooks had 88 pages for food storage, 26.05 pages for food poisoning, 7 pages for food contamination, and 2 pages for kitchen hygiene. Physical education textbooks had 15 pages about food storage, 4 pages for food poisoning, 5 pages for food contamination, and 1 page for kitchen hygiene. 5) Social studies textbooks had 5 pages for food storage, 4 pages for insect and rodent control, 3 pages for food contamination. 6) The number of pages dealing with food sanitation in elementary school level textbooks were 20 in physical education, 13 in home economics, 12 in social studies, 3 in science respectively. 7) The number of pages dealing with food sanitation in junior high school level textbooks were 31.05 in home economics, and 7.00 in physical education textbooks. 31.50 pages were about food storage, 6 pages about food poisoning, 13 pages about insect and rodent control, and 1 page about kitchen hygiene. 8) The number of pages dealing with food sanitation in senior high school level textbooks were 101.05 in home economics and 4 in physical education textbooks. 64 pages were about food storage, 21.05 about food poisoning, 13 about insect and rodent control, 4 about kitchen hygiene, and 3 about food contamination. 9) Pictures, drawings and tables were used in explaining food sanitation in the textbooks, 32 drawings of a total of 38 cuts in elementary school level textbooks, 8 pictures of 10 cuts in junior high school level and 13 tables of 14 cuts in senior high school level were used. 10) 5th grade textbooks of elementary school did not have a subject on food poisoning. Other grade textbooks in elementary school level did not contain a subject on food contamination and insect and rodent control. It's recommended that these subjects be contained in the textbooks. 11) It is necessary to teach a subject on health or health and environment independently and contain food sanitation in the subject. It is recommended that a textbook on health or health and environment be published and taught to students. 12) It is recommended that teachers specialized in health education be assigened to schools to teach health related subjects. 13) It is recommended that book publishers use the latest information in the textbooks and technical terms be unified.

In the era of the 4^th industrial revolution and convergence, various discussions and studies have been conducted to develop future social talents, and through this, the need for creative convergence talents is increasing. In line with the change to a software-oriented society, countries around the world are trying to strengthen SW education, but high school students' awareness of the necessity of information subject and SW education that is the center of convergence is insufficient. Therefore, opportunities for convergence of the information subject and various fields should be provided. In this study, information education was converged to the science exploration experiment subject to construct an educational program that can develop creative convergence, and a convergence class using physical computing were applied to high school students for 9 hours. As a result of the experiment, the recognition of SW education of the experimental group was improved, and it was confirmed that the learner's convergence literacy of the experimental group was statistically different from that of the control group that conducted the general science experiment class.

The aim of this study was to assess adolescents' sexuality and to gather student opinions on current school-based sex education in South Korea. A self-administered questionnaire survey was conducted in Seoul, Incheon, and Kyunggi Province to assess the status and needs of high school sexuality education. Survey data was obtained from 1,130 senior high school students. The rates of sexual intercourse for boys and girls were 33.1% and 13.2% respectively. Boys were more likely to be sexually involved (p = .000) and experienced earlier at first sexual intercourse than girls (p = .006). Among students who had sexual intercourse, only 20.3% (21.1% of boys and 19.1% of girls) used contraceptives at first sexual intercourse. The proportion of respondents who had had sexual intercourse was higher among those with poor self-perceived academic performance (p = .000). The proportion was also higher among those with a boy or girl friend (p = .000). Other risk-taking behaviors such as smoking and drinking were associated with sexual activity (p = .000). This study found that most students were not satisfied with sex education because of teachers' lack of information and skills in delivering it. Most teachers providing sex education were not qualified and/or trained. They should receive adequate training and guidelines for the training. Training should also give teachers time to practice and become comfortable in delivering it.

Along with a variety of coding education, physical computing education for controlling various sensors is being actively conducted for elementary, middle, and high school students in line with the era of the fourth industrial revolution. A problem with physical computing education using Arduino is pin connection errors between Arduino and various sensors. Most of the students who come into contact with the Arduino for the first time often do not know the purpose of the Arduino pin and the connection position of the pin. Also, hardware built with incorrect pin connections to the Arduino board often does not work properly. If this case continues, students will lose interest in coding education. Therefore, in this paper, we implemented an augmented reality application that informs the connection process of the Arduino board and the sensor during physical computing coding education using Arduino, and designed and implemented educational content for the Arduino pin position and connection process. First, we explain the role of the Arduino board and the sensor and the location of the pins. After that, the students run the educational augmented reality educational content using their smartphones and check the correct pin connection process between the Arduino and the sensor. In the physical computing education, augmented reality content is used to increase the understanding and immersion of the class. It is expected that the educational effect will also increase by inducing fun and interest in physical computing coding education.
