The aim of this study is to characterize the optical properties of white light-emitting diodes lighting modules and then to evaluate the sensitivity of students and teachers in reacting to the optical properties of these modules. For the sake of this study, each of 5 lighting modules was introduced to the 5 test cabinets. The 5 test cabinets were evaluated and analyzed the student and teacher's sensitivity reaction. We have selected If questions on sensitivity of the lighting and evaluated these questions with semantic differential method. To verify the reliability and objectivity of the questions, the feasibility survey was carried out by a preliminary test. As a result of the test, the sensitivities on the test cabinets were classified the 4 factors, namely, activity as the first factor, stability as the second one , potency as the third one and sensitive image as the fourth one respectively. By the evaluation of student and teacher's sensitivity on the correlated color temperature, they preferred the cabinet with the higher color temperature in view of the activity and potency. And they preferred the cabinet with the lower color temperature in view of the stability factor. In the sensitive image, they preferred the 5800K, bluish white lighting regardless of the color temperature. By the evaluation on the color rendering index, they preferred the cabinet with the higher color rendering index in view of the activity, stability and sensitive image. In the potency factor, they preferred the white lighting with the middle color rendering index.

As environmental issues have become a worldwide concern after the 20th century, the idea and the term of 'green growth development' has become familiar to the public. After 2008, the green growth development dramatically became an important ideology in Korea; thus industries, studies and product investments in relation are in active progress. Following the trend, the latter major unit of the middle school textbook "Technology & Home Economics" was named the revision of elementary, middle and high school textbooks in 2009. The learning goal of 'green' or 'eco-friendly' of the revised edition of the textbook will guide the middle school students to have better understanding of the issues of clothing habits and the environment. Furthermore, students will be able to apply the 'green' concepts in their real life and put eco-friendly clothing habits into action. Thus, the practice of effective learning will depend on the quality of the current issue of the textbook. Therefore this study analyzes the eco-friendly contents of the semi-unit from 7 different textbooks and presents an example of textbook production to the preliminary teacher of home economics.

BACKGROUND/OBJECTIVES: Nutrition knowledge has been reported to have a weak positive effect on healthy eating behavior. This study aimed to determine if there was a difference in nutrition knowledge depending on the choice of science subject in high school and whether that affected the actual eating habits of college students in Japan. SUBJECTS/METHODS: The subjects were 514 college students, the majority first-year students, in 3 cities in Japan. A questionnaire survey was conducted on elective subjects in science in high school, diet (11 items), lifestyle (5 items), and nutrition knowledge (34 questions). The preliminary survey was conducted on 47 students in the fall of 2019, and the full-scale survey was conducted in May-June and October-November 2021 at the end of lectures for the first-year students. RESULTS: The students in the high-score group (24-31 points, n = 180) had a higher intake of vegetables (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.12-2.82; P = 0.015) and breakfast (OR, 1.64; 95% CI, 1.03-2.60; P = 0.035), and a reduced intake of fast food (OR, 0.27; 95% CI, 0.14-0.51; P < 0.001) than those in the low-score group (6-19 points, n = 150). Only the biology and chemistry students had significantly higher nutrition scores than the other groups (all: P < 0.001), but no significant difference was found between the other groups. Understanding nutrition learned in elementary and junior high school is appropriate, while molecular structure, recommended amount, and food poisoning were insufficient. CONCLUSIONS: Knowledge of nutrition appears to have a positive effect on the actual eating habits of college students. Although biology and chemistry in high school may help students understand the foundations of good nutrition, specialized food education may be required to make informed dietary choices.

Online teaching has become a daily routine in schools after 2020, and at the same time, the ability to design and conduct classes using smart devices and apps is becoming more important to teachers. Therefore, in this study, we tried to find out how the demonstration of classes using smart devices and apps online has an effect on the intentions of prospective teachers who want to use them in the future. To this end, classes were designed according to the design principles for improving smart education capabilities of pre-service teachers, and the classes were conducted for pre-service teachers. Afterwards, the variables included in the UTAUT model, such as Performance Expectancy, effort Expectancy, social influence, Voluntariness of Use, Behavioral Intention, and Facilitating Conditions, were measured before and after classes, respectively, and the effectiveness of the class was verified through t-test of response samples. As a result, it was confirmed that all variables except the Facilitating Conditions had a significant positive(+) effect. These results suggest that online class demonstration education can be a way for pre-service teachers to more practically adapt to the educational field where smart education is required.

The purpose of this study was to determine the perception and understanding of Free Learning Semester (FLS) in home economics teachers and to provide basic informations for effective implement of FLS in future school curricula. Home economics teachers perceived that the objective of FLS was to help students explore their careers and make preliminary decisions. In addition, teachers thought that FLS should be run by active students' participation to find out their dreams and talents. However, teachers felt difficulties in obtaining information or documents related to implementing FLS. Moreover, there were lack of connected activities with local communities to operate FLS. Teachers recognized that it is necessary to receive FLS-related education. Regarding home economics teachers' role in FLS implement, they should provide career education with a perspective of lifelong career and nurture students' capability to lead their lives by themselves. In that sense, FLS should help students find out their dreams and talents, think about their career, set up lifelong career plan through home economics education, and nurture capability to lead their lives. In addition, home economics teachers should provide continuous career education in home economics education at academic semesters.

Purpose: The purpose of this preliminary study was to investigate gender equality consciousness among elementary school teachers and the 6th graders at 3 rural area in Korea. Methods: There were 78 teachers and 323 6th graders from five elementary schools in Y area in Jeonnam province. The data was collected with 3 structured self-reported questionnaire from June to July 2003. The instrument, which was developed by Korean Women Development Institute to test gender equality consciousness, was composed of 20-items (Cronbach's ${\alpha}$ = .87 in teachr group; Cronbach's ${\alpha}$ = .83 in children group) with four subcategories: family life, school life, business life, and social life. The data was analyzed by a one-way ANOVA and t-test using SPSS/PC+. Results: 1. Teachers' gender equality consciousness: The teachers' gender equality consciousness was significantly more affirmative in females (t = 5.313, p = .001) and in the younger teacher group (F = 24.710, p = .001). On the other hand, there was no significant difference according to marital status. The differences in all four subcategories were also significantly affirmative in the female and younger teacher group. 2. Students' gender equality consciousness: The gender equality consciousness among the 6th graders was somewhat different from the teachers'. School girls (t = 8.988, p = .001) and children from double income families (t = 3.171, p = .042) were more affirmative in gender equality consciousness than the other groups. In the four sub-categories, school girls were also significantly more affirmative in all four subcategories. On the other hand, according to the family income source, the children from double income families also tended to be more affirmative only in the subcategory of family life (t = 3.196, p = .042) Conclusions: Gender equality consciousness is remarkably different according to gender both in Korean elementary school teachers and in school children. Age was a key variable in teachers for gender equality consciousness. Further research in gender equality consciousness of parents, school principals and urban school population would be useful. In order to promote gender equality consciousness, various educational materials and a mass education campaign should be developed.

The purpose of this study was to identify latent classes in school readiness which were measured by both parents and teachers, and to test the relationship with school adaption, academic abilities, problematic behaviors, self-esteem, and happiness. Latent Profile Analysis (LPA), MANOVA, and one-way ANOVA were conducted using the data of 1,154 1st to 3rd grade elementary school students, and the data was collected between the 7th year (2014) to the 10th year (2017) from the Korean Children and Youth Panel Study. The results of study were as follows. First, four school readiness groups were identified: the consistent low group, parent perceived high group, the teacher perceived high group, the consistent high group. Second, the consistent high group and the teacher perceived high group showed relatively better academic abilities and school adaption than the consistent low group. Furthermore, the consistent high group showed higher academic abilities, self-esteem, and happiness, but lower problematic behaviors than the consistent low group. The findings of this study could be utilized as preliminary data for understanding school readiness to promote successful school adaption and psychological well-being of children.

This study aims to verify the effect of school library education service on the information literacy ability of high school students in the poor economic environment. For this purpose, we narrowed down to 215 high school first graders with substandard educational conditions, and then implemented information literacy education. The results of the information literacy test were compared, before and after the information literacy service. The preliminary tests of 15 schools including the targeted school were conducted, and we found that the results of the self-evaluation in those 15 schools exceed those with other generally good educational conditions. We considered in all aspects to find out how to overcome the information literacy gap through information literacy programs. Reflecting on the previous research verifying that the difference in educational environment affects the information literacy, we can confirm that the information literacy education service, which is the core service of the school library, can narrow the information literacy gap. We hope that this study will be a basis for the systematic establishment of information literacy education in public education.
