This study aimed to investigate how the current elementary school teachers think about nutrition education, how they are teaching, and what kind of problems have occurred. And this study was made to provide basic materials to be used for the effective nutrition education in the elementary school. The survey was done on 60 elementary school teachers and 570 elementary school students of the 5th and 6th grade in Gyeonggi Province by questionnaire and analyzed for the perception of nutrition education, current status of nutrition education, nutrition knowledge and cooking knowledge. The average scores of nutrition knowledge were 2.72 for male and 3.75 for female students out of full score of 5. The fifth grade students learned more nutrition education than the sixth grade ones in accordance with the different curricula. Nutrition education was taught as apart of other subjects(87%) and mainly done by lectures. For most of the students, information source of the nutrition education was the meal service(47.4%) and the most common one was the Internet that 38.1 % of the teachers used. Most of the students responded that nutrition education was necessary in the curriculum of elementary school for proper growth(36.2%), intelligence(25.9%), health(21.5%), and dieting(16.4%). The perception for the suitable teacher was in the order of nutrition specialist and dietician. And the right time of the related class was in the order of spare time everyday, a special activity time, and the meal service time. The important contents of nutrition education were in the order of proper eating habits, growth & nutrition, food hygiene and diseases. Nutrition problems of the elementary students were in the order of unbalanced diet, too much ingestion of processed and instant foods, lack of table manners, and child fatness and weakness. 80.0% of the teachers supported the early nutrition education and demanded it should begin when children are in kindergarten. The analysis showed that nutrition education should be taught by parents(29.4%), teachers(29.2%), and nutritionists(25.9%) and that family and school should cooperate closely. Main responses of the teachers to the children's problems were that they had too much instant food, did not eat in a variety, and had no manners in eating. Ironically, they thought malnutrition, fainting and growth stunt were not important nutrition related problems.

It was performed to find out difference of the nutritional contents between chungjung chicken meats grown chemicals free and general chicken meats. The chungjung chicken was eat and given feeds of good quality mixed living microbial agent, power of ginseng leaves and by-product of extract liquefied sea foods from fishes producted clean area of the Western Sea, including plentiful calciums, amino acids, docosahexanoic acid(DHA) etc. Addition of they improved chungjung chicken yields and meat quality compared to general chicken given feeds mixed antibiotic etc. Also, chungjung chickens eaten miced type develop resistance to in disease. There were significant trend in crude proteins, calciums, crude lipids contents, and unsaturated fatty acids between the chungjung chicken meats and the general chicken meats. The crude proteins and calciums contents were higher in the chungjung chicken meats than the general chicken meats, but the crude lipids contents were higher in the general chicken meats than that. Also, contents of the n6 fatty acids and n3 fatty acids in chungjung meats were higher than that. Especially, contents of DHA in the chungjung chicken meats were detected higher than the general chicken meats. Therefore, the results from this experiments will provide a information for the nutritional knowledge of the 'white meats', especially the clean chicken meats.

The relationship between dietary practices and juvenile delinquency was studied using a dietary survey. Subjects were selected from juvenile delinquents who were under the supervision of the Seoul Probation Office of the Ministry of Justice. The study group consisted of 52 male and 52 female delinquents. As a control group, 104 exemplary high school students were selected in Seoul. A questionnaire was designed to find out the subjects' general characteristics, dietary habits, lifestyle, eating behavior, food frequency, and nutrient intake using the 24-hour recall method. Compared to the exemplary students, the juvenile delinquents were significantly different in education level, family status, monthly allowance, residence status, breast fed, parents' education level, parents' concern. In dietary habits, fifty-eight percent of the juvenile delinquents ate 2 or fewer meals per day, preferred to eat with friends, and liked hot tasting foods. The juvenile delinquents consumed more ion drinks (OR = 9.26 CI: 3.83 -22.37), rameon (OR = 7.67 CI: 3.21 - 18.33), cola (OR = 6.75 CI: 2.91 - 15.69), soft drinks (OR = 6.12 CI: 2.53- 14.81), steamed korean sausage (OR = 5.34 CI:2.31 - 12.32), hamburger (OR = 5.15 CI: 1.91 - 13.87), kimbab (OR = 3.63 CI: 1.76-7.46), ddokbokgi (OR = 3.17 CI: 1.58-6.38), candy (OR = 3.08 CI: 1.41-6.73), white rice (OR = 2.59 CI: 1.19-5.64), hotdog (OR = 2.52 CI: 1.31-4.86), and less rice mixed with grains (OR = 0.02 CI: 0.01-0.05), tangerine (OR = 0.06 CI: 0.02 - 0.20), milk (OR = 0.29 CI: 0.14 - 0.60), roasted fish (OR = 0.32 CI: 0.28-0.99, anchovy (OR = 0.35 CI: 0.17 - 0.72), seaweed (OR = 0.37 CI: 0.16 - 0.83), and tofu (OR = 0.48 CI: 0.23-0.99) than the exemplary students. With respect to the juvenile delinquents, the nutrient intakes lower than 75％ of the Korean RDA were for riboflavin (75.0％) and calcium (47.9％) among the boys, and calcium (46.9％) and iron (60.4％) among the girls. To prevent juvenile delinquency, nutritional education and well-balanced school food service meals should be emphasized so as to improve the management of dietary practices.

In this study, the microbial levels on mixed vegetable salads, fresh fruits, and frozen fruits distributed in Korea were comparatively analyzed by food group, region, and quarter. Samples were collected from big markets in large cities from 2018 to 2019 and used for microbiological analysis. The levels of aerobic bacteria for mixed vegetable salads, fresh fruits, and frozen fruits were 6.48, 5.07, and 3.78 log CFU/g, respectively. As a result of analyzing the quarterly contamination levels of aerobic bacteria, the first quarter contamination level was 5.12 log CFU/g while the second quarter showed 6.26 log CFU/g, the third quarter 5.73 log CFU/g, and the fourth quarter 4.42 log CFU/g. A higher number of aerobic bacteria was observed in the second and third quarters when the temperature was higher. There was no difference in the number of bacteria by region. The levels of the coliform group were 1.98 - 3.93 log CFU/g in all samples, and Escherichia coli was detected at 1.38 log CFU/g in 3 out of 27 mixed vegetable salads. Since the mixed vegetable salad and fresh fruit used in this study exceeded the standard (3 log CFU/g) for unheated foods and E. coli was detected in three fresh fruits, stricter hygiene management in the manufacturing stage of salads and fresh fruit is required.

As the school lunch program is expanding to middle and high schools in Korea, a survey has been conducted to provide informations of the types and menus which are most favored on 190 middle and high school students in Metropolitan area. The sources/menus of foods relating to their lunches were proportionally ranked as: school food services (54.2%): individual lunch-box from home(37.4%); take-out lunch box(3.7%): school cafeterias(1.6%): and commercial restaurant, undefined, and skip a meal(1.1%). For the present practices for lunch, 52.1 and 47.9% of the students responded satisfaction on its sources and menus, respectively. A meal valued less than 2,000 won was paid by 54.9% of the respondents. In the meantime, 33.7 and 55.4% of the students were unsatisfied with lunch box from home and school cafeteria of the present lunch practices, respectively. The reasons against their satisfactions were enumerated as their preferences for take-out lunch box(22.2%), school cafeteria(21.0%), outside restaurant(17.3%), individual lunch-box from home(16.1%), school cafeterias(8.6%), and undefined (14.8%). For the individual lunch-box from home, two major obstacles, i.e., it is neither warm to eat, nor diverse/properly-sized in side dishes, were reasons for dissatisfaction of the students. The school lunch programs were blamed for its poor taste and lacks of variety and volume of the side dish which is mostly composed of kimchi, seasoned vegetables, and bulgogi. The most popular side dishes were pork- or fish cutlets, hams, and sausages while food with carrots, garlics or red peppers, vegetables like pumpkins, lotus roots, and seasoned vegetables were mostly disliked. It was concluded that the school lunch programs for middle- and high school students could be settled down by preparing with well-nourished food items that suits students' taste best and be served at right temperature.

The purpose of this study was to investigate food safety knowledge, food safety attitudes, and handling behavior in the elderly. The survey was conducted on 358 individuals over 65 years old in urban and rural areas. Data were analyzed with descriptive analysis and ${\chi}^2$ test analysis of variance using SPSS. From the results on elderly's food safety knowledge, the item 'tangerines should be washed before eating' was correctly answered by urban subjects (75.4%) than rural subjects (49.7%). 'Is it okay to cook meat left on the sink since afternoon in the evening' showed the lowest correct answer rate in both urban (23.1%) and rural (31.9%) subjects. For the item related to food keeping, 'Bacterial cells do not multiply in Samgyetang when it is kept in a refrigerator right after boiling thoroughly', 58.5% of urban and 54.6% of rural elderly answered correctly. Most elderly people showed a tendency to think that boiled foods might be safe to eat. Secondly, for food safety attitudes, urban elderly had more proper attitude regarding the item, 'Namul is very tasty only when mixed with bare hands' (disagree rate 34.9%) than rural elderly (P<0.05)'. On the other hand, rural elderly had more positive attitudes regarding the store principle "first in, first out" compared to urban elderly (P<0.001). Thirdly, regarding food safety behaviors, only 67.9% of urban and 58.7% of rural elderly responded that they washed their hands right after answering the telephone while cooking. Exactly 33.8% of urban and 39.6% of rural older people replied 'defrost meat on top of sink or table' as the defrost method for frozen foods, showing that elderly did not recognize the risk of foodborne illness during improper defrosting at room temperature.

This study is conducted to investigate the contents of ${\beta}$-carotene and retinol in bap (e.g. gimbap, bokkeumbap, sushi, deopbap, bibimbap), guk (e.g. sundaeguk, seonjiguk), tang (e.g. galbitang, chueotang), and jjigae (e.g. dongtaejjigae, kimchi jjigae with port) by using saponification extraction and HPLC analysis. The samples were collected from six regions in Korea (Gangwon-do, Gyeonggi-do, Gyeongsang-do, Seoul, Jeonla-do, Chuncheong-do). In bap, the ${\beta}$-carotene contents of kimchi gimbap (234.459~719.180 ${\mu}g/100g$), bibimbap (200.091~489.867 ${\mu}g/100g$) and pork deopbap (228.876~778.591 ${\mu}g/100g$) were higher than that of sushi (0.000~41.234 ${\mu}g/100g$), and jajangbap (4.833~28.141 ${\mu}g/100g$). The retinol contents of bap was 0.000~60.418 ${\mu}g/100g$, among which, omelet rice (13.974~60.418 ${\mu}g/100g$) showed the highest amount of retinol. Among the analyzed guk (tang) and jjigae, higher contents of ${\beta}$-carotene were observed in chueoutang (346.261~843.947 ${\mu}g/100g$), kimchi jjigae with pork (178.558~352.604 ${\mu}g/100g$) and altang (169.443~175.287 ${\mu}g/100g$). The retinol of guk (tang) and jjigae were not detected to doganitang, gomtang, naejangtang, chueotang and soy sprout haejangguk.

Purpose: The aim of this study was to investigate children's eating behaviors and teachers' feeding practices during mealtime at child-care centers. In addition, it focused on the difference of teachers' feeding practices on children age under 2 years ( ${\leq}2$ years old) and 3 years and older (3~5 years old). Methods: A total of 169 teachers working at childcare centers in Geumcheon-gu, Seoul, Korea, completed self-report questionnaires in December 2013. The questionnaires were composed of questions on children's eating behaviors, feeding practices; 'Explain', 'Praise', 'Modeling', 'Indulgent', 'Insist' and 'Reward', interaction with home, and a range of demographic information (analysis rate: 51.2%). Results: Approximately 59.2% of teachers had not taken a class on feeding practice and the average score for nutrition knowledge was 14.6 out of 30 points. The most undesirable eating behavior of children during mealtime was 'eating while walking around (36.7%)' both ' ${\leq}2$ years old' and '3~5 years old'. Regarding feeding practices according to children's undesirable eating behaviors during mealtime, there were differences between age groups. When children did not eat all of the foods that were served and did not clean up silverware or seats after having food, teachers caring for '3~5 years old' practiced 'Explain'. However, percentages of those who practiced 'Indulgent' and 'Modeling' were significantly higher in teachers caring for ' ${\leq}2$ years old' than '3~5 years old'. Conclusion: These findings indicated that teachers caring for children lack education and knowledge about nutrition and feeding practice. In addition, verbal feeding practices, like explain, were mainly used by teachers. As a result, for teachers, guidelines and programs for learning about age appropriate feeding practice during mealtime at child-care centers may be needed.
