This study was conducted to investigate the dietary behavior and health-related lifestyles of university students in Incheon arear Self administered questionnaires were collected ken 179 food and nutrition major and non-major students. Statistical data analysis was completed using a SPSS v.10.0 program. The results are summarized as follows: The average weight, height, BMI and PIBW of the major and non-major male and female students were 69.89kg, 172.89cm, 23.4 and 106.49 ; 67.27kg, 173.98cm, 22.2 and 101.35 ; 50.61kg, 161.20cm, 19.53 and 92.25 ; 53.77kg, 161.53cm, 20.56 and 97.18, respectively. The breakfast skipping ratio of the subjects were very high, which was mainly due to the reason“lack of time”More than 75% of male students and 61% of female students responded to have lunch at university canteens or restaurants around campus regularly. About 56% of male students and 68% of female students responded to have dinner irregularly, which mainly caused by the reasons“irregularity of lecture”and “appointment with friends”. The ratio of snacks intake of the subjects were high; Ramyun was the snack item taken the most by the male students and fruits and cookies by the female ones. More than 50% male students and 2% of female students were smokers. A half of students dunk alcohol once or twice a week. The dietary behaviors and health-related lifestyles between major and non-major male students tended to be very similar. The major female students showed more health-oriented dietary behaviors in comparison with the non-major ones. Therefore, they should have a major-oriented and practically organized nutritional education program to correct their dietary behaviors and health-related lifestyles fur health.

In this paper, we proposed "Future Design and Success Engineering in Global Society by Self-Innovation" (an abbreviated name: FDSE). We started to make a small experiment between Korea Maritime University and Yamagata University at the current year. After inspecting the results, especially, successful and unsuccessful points in our lecture, we have to develop the strong points and amend the week points, through making the analysis of success-failure, which is his favorite management method. We have to level up the contents of our work in the future. The students for this lecture would learn from experiences of "the common knowledge (common field of discussion)", held common languages, common thought, common system. They filled up the blanks of "The Matrix Frame" which is mentioned in the previous report, and they expressed their own way of life (work, study). As a matter of course, their personal private affairs must not be made public. It is quite happy that the cultural, economical exchanges between Korea and Japan are now in full flourish and people do a lot of traveling each other. However, if this project will start on the educational global standard, we have a world-wide significance. Moreover, we can promote goodwill between Korea and Japan, and also we can contribute to a better international understanding and the peace of the world by students in both Universities. We hope that candidates for this lecture will have a rounded personality and be a life worthy of human being for realizing Self-Actualization in "Motivation and Personality" by Abraham Maslow.

This study was conducted to investigate the dietary behaviors and health-related lifestyles, according to exercise habits, of female university students in the Jeonju area. Self-administered questionnaires were collected from 285 students, and the statistical data analysis was completed using the SPSS v. 10.0 program. The results are summarized as follows. The weight, height, and BMI averages of the regular exercise and non-exercise groups were 53.05 kg, 162.46 cm, and 20.23, and 50.81 kg, 161.46 cm, and 19.48, respectively. The breakfast skipping ratio was higher in the non-exercise group than the exercise group. More than 72% of the exercise and 71% of the non-exercise group responded to regularly having lunch at the university canteens or restaurants around campus. Approximately 70% of the exercise and 71% of the non-exercise group responded to having dinner irregularly, which was mainly caused by reasons such as 'irregularity of life style' and 'appointments with friends'. The snack intake ratios of the exercise and non-exercise groups were high, but the exercise group ate more fruit, yogurt, and milk than the non-exercise group. The favorite sports of the exercise group were 'walk(jogging)', 'yoga', 'bicycle,' 'swim,' etc. In particular, 5.3% of the exercise group had ridden a bicycle to the university. More than 97% of the students were non-smokers. About 14% of the exercise and 15% of the non-exercise group rank alcohol once or twice a week. The exercise group did not show exceptional health-oriented dietary behaviors in comparison to the non-exorcise group. Therefore, an exercise-oriented nutrition education program would be beneficial to the students, in order to improve their dietary behaviors and health-related lifestyles.

The hyoscyamine 6${\beta}$-hydroxylase (h6h) gene was introduced into the genome of Scopolia parviflora through the Agrobacterium rhizogenes binary vector system. The enzyme was expressed ally and tissue specific selectively in roots, resulting in five transgenic hairy root lines. The presence of the h6h gene in kanamycin-resistant hairy roots and its overexpression were confirmed by polymerase chain reaction (PCR), Northern blotting, and Western blotting, respectively. In the transgenic hairy root lines which constitutively expressed the H6H enzyme, hyoscyamine and scopolamine accumulated in high concentration. Among the transgenic hairy root lines that expressed the H6H enzyme, only two were more productive. The levels of tropane alkaloids in transgenic hairy root varied greatly: The best transgenic line (#5) contained 8.12 mg of scopolamine per g dry weight, which produced the compound three times more than wild-type root. These results suggest a possibility of improving the yield of tropane alkaloids in hairy root lines by genetic and metabolic engineering.

Tunicates are known to contain biologically active materials and one species in particular, the sea peach (Halocynthia aurantium), has not been thoroughly studied. In this study we aimed to analyze the fatty acids profile of the H. aurantium body wall and its immunomodulatory effects on RAW264.7 macrophage-like cells. The fatty acids were classified into three categories: saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs). Omega-3 fatty acid content, including EPA and DHA, was higher than omega-6 fatty acids. H. aurantium body wall fatty acids exhibited enhanced immune response and anti-inflammatory effects on RAW264.7 macrophage-like cells. Under normal conditions, fatty acids significantly increase nitric oxide (NO) and PGE2 production in a dose-dependent manner, thereby improving the immune response. On the other hand, in LPS-treated RAW264.7 cells, fatty acids significantly decreased nitric oxide (NO) and PGE2 production in a dose-dependent manner, thereby enhancing anti-inflammatory effects. Fatty acids transcriptionally control the expression of the immune-associated genes, iNOS, IL-1β, IL-6, COX-2, and TNF-α, via the MAPK and NF-κB signaling cascades in RAW264.7 cells. However, in LPS-stimulated RAW264.7 cells, H. aurantium body wall fatty acids significantly inhibited expression of inflammatory cytokine; similarly, production of COX-2 and PGE2 was inhibited. The results of our present study provide insight into the immune-improving and anti-inflammatory effects of H. aurantium body wall fatty acids on macrophages. In addition, our study demonstrates that H. aurantium body wall is a potential source of immune regulatory components.

The advent of the carbon neutrality era has led to a paradigm shift in education toward ecological transition education. It is time to understand the concept and practice of ecological transition education pursued in the 2022 revised curriculum and prepare for changes to the main life education covered in home economics education. Therefore, the purpose of this study is to explore the role of home economics education for carbon neutrality for future generations who will have to live in the era of rapidly changing climate crisis, and to propose a practice plan for ecological transition education in the main living area based on the educational contents of the 2022 revised curriculum. To achieve these objectives, this study reviewed previous research on carbon neutrality and ecological transition education, analyzed the curriculum for main life from the first curriculum to the 2022 revised curriculum, and proposed the direction of main life education for ecological transition education. Through this study, the importance of carbon neutrality and ecological transition can be emphasized in home economics education, and it is expected that it can be used as a basis for realizing ecological transition education in actual education sites.

This pilot study was performed to produce data of the Children's Dietary Life Safety (CDLS) Index which is required by the Special Act on Safety Management of Children's Dietary Life and to evaluate the CDLS Index for 7 metropolitan cities and 9 provinces in Korea. To calculate the CDLS Index score, data regarding the evaluation indicators in the children's food safety domain and children's nutrition safety domain were collected from the local governments in 2009. For data regarding the indicators in the children's perception & practice domain, a survey was conducted on 2,400 5th grade children selected by stratified sampling in 16 local areas. Relative scores of indicators in each domain were calculated using the data provided by local governments and the survey, the weights are applied on relative scores, and then the CDLS Index scores of local governments were produced by adding scores of the 3 domains. The national average scores of the food safety domain, the nutrition safety domain and the perception and practice domain were 23.74 (14.67-26.50 on a 40-point scale), 16.65 (12.25-19.60 on a 40-point scale), and 14.88 (14.16-15.30 on a 20-point scale), respectively. The national average score of the CDLS Index which was produced by adding the scores of the three domains was 55.27 ranging 46.44-58.94 among local governments. The CDLS Index scores produced in this study may provide the motivation for comparing relative accomplishment and for actively achieving the goals through establishment of the target value by local governments. Also, it can be used as useful data for the establishment and improvement of children's dietary life safety policy at the national level.

This study was performed to analyze children's perceptions and practice levels according to gender and obesity status using a dietary life safety index. A national survey was conducted on fifth grade children (n = 2,400), who were selected using three-stage stratified cluster sampling from 16 provinces. The average height was 144.8 cm, and weight was 38.8 kg. The average body mass index was 18.4 kg/$m^2$ and underweight, overweight, and obese children were identified using the 2009 KHNANES cutoff values, which were 5.3%, 10%, and 5.9%, respectively. The perception and practice scores for hand-washing prior to eating were high and the score for willing to buy at a clean store was also high. However, students answered that the hygiene level of food stores near the school was poor. More students skipped breakfast than lunch or dinner. The frequency scores for fruit and vegetables were significantly higher for girls than those for boys. Students had a good understanding of nutrition labeling but did not frequently check the label. Seventy-five percent of the students tried to avoid high calorie foods with low nutritional value, but only 40% had the appropriate knowledge about high calorie foods with low nutritional value. Girls had better dietary life perception and practice levels than those of boys. No differences in perception or practice levels were observed based on obesity status. Nutrition education on the importance of eating breakfast and having accurate knowledge on nutrition labeling and high calorie foods with low nutritional value is needed. Behavior-centered education should be implemented to improve the perceptions and practice level of student's dietary life.
