This study was designed to obtain basic data for the globalization of Korean food and the expansion of food exports through contract foodservices. A survey of dietary habits and attitudes toward school foodservices was given to students in three American international schools served by a domestic contract foodservice management company located in Seoul and Gyeonggi area. The results showed an average of three meals taken daily 3.39 times for male students and 2.95 times for female students and the time required for a meal was about 24~26 minutes. The average breakfast frequency was 5.10 times(4.59 times for male students and 5.35 times for female students) and many students reported skipping breakfast due to a lack of time. The average weekly frequency of dining out was 1.78 times(2.15 times for male students and 1.60 times for female students). In all schools, irrespective of gender and grade, students responded that a desire for snacking was 'why they want to have cookies', and snacking hours were frequently listed as 'between noon and evening'. Many also responded that an unbalanced diet is the reason some snacks are 'not to their taste'. Overall, students were highly satisfied with the foodservice menu, although there was a significant difference in what was considered proper food temperature, proper food seasoning, suitable amounts of food, and freshness of food. Male and female students were specifically highly satisfied with the 'freshness of food materials' and 'variety of menu' respectively. Overall, all students were highly satisfied with the foodservice, including the 'cleanliness of tables and trays'.

The purpose of this study was to analyze the relations of children's skipping meals after researching eating habits and lifestyle, parents' appreciation in nutrition behavior and dietary intake, throughout the research based on 4th to 6th grade students, total of 362 children at an elementary school in Inchoen. There were 104 students in skipping meals group and 258 students in eating meals group, with the average ages of 10.9, and 10.8, respectively. The average height and weight were 144.5 cm, 38.6 kg for skipping meals group, and 145.7 cm, 39.3 kg for eating meals group. Parents' appreciation of importance in breakfast showed a significant difference in whether children skip the meals or not (p<0.01). 43.7% of parents in skipping meals group answered that they serve breakfast everyday, compared to eating meals group with the percentage of 94.9%, showing significant difference in frequency of serving breakfast for their children (p<0.001). The skipping meals group answered that the reason they do not have breakfast is because they do not have time, which showed the highest percentage of 41.2%. For the eating meals group, 40.5% of students answered that they do not have appetite, which also showed difference (p<0.001). The skipping meals group tended to wake up later than those who have breakfast in the morning(p<0.01). The breakfast time for skipping meals group was later than the eating meals group, and according to whether they have breakfast of not, it showed a difference as well(p<0.01). Total score of nutrition attitude in skipping meals group and eating meals group were 30.8 and 32.1, showing that eating meals group showed more good in nutrition attitude (p<0.05). Daily intakes of energy (p<0.01) and protein (p<0.01) in skipping meals group were significantly lower than those in eating meals group. Skipping meals group bad lower rates in INQs of protein (p<0.01) and zinc (p<0.01), showing that skipping meals group is having low quality meals in nutrition. In conclusion, this study revealed that students with skipping meals are more likely to have meals that lacks nutrition or have low quality meals, and the time of rising hour in the morning, frequency of eating snacks can also affect whether or not they skip meals.

There is a rising trend in obesity due to various factors, including changes in eating habits, lack of exercise, and genetic and psychological factors. Citrus peel has been reported to prevent obesity via antioxidative, antihypertensive, and LDL cholesterol-lowering effects. This study investigated the effects of citrus peel extract fermented with or without Aspergillus oryzae in a mouse model of diet-induced obesity. The animals were divided into four groups: a high-fat diet group (HFD), a normal fat diet (NFD) group, a citrus peel extract (CP) group, and a citrus peel extract fermented with A. oryzae (CPA) group. The citrus peel extract improved lipid metabolism and weight loss in the high-fat diet-induced obese mouse model. As expected, the body weight was higher in the HFD group compared with the NFD, CP, and CPA groups. However, the concentrations of total cholesterol (TG) and triglyceride (TC) in the serum and liver of the CP and CPA groups were lower than in the HFD group. There were no significant differences in the HDL cholesterol concentration among the groups. Taken together, our results suggest that extract of citrus peel biotransformed with A. oryzae had more antiobesity activity than citrus peel not transformed by A. oryzae through the fermentation of metabolites.

The purpose of this study was to investigate the effects of the regular Upright Body Type Excercise on posture, muscle strength of leg, lung capacity and depression of people with mental illness. The subjects of this study were recruited from B mental health center (5 years and more mental illness patients, n=19) located in P city. For the exercise group, They were carried out the Upright Body Type Excercise Program during 8 weeks (60 min/time, 3 times/week). They were randomly divided into two groups. Exercise group (n=10) and Control group (n=9). And also, they were agreed with consent forms before the experiments. Research results were as follows. Through the upper body type exercise, there was significantly difference in PEF and FEV1/FVC in the trained group. And also, there was much improved in depression level in the trained group. The change of melancholy feeling before and after the program was not statistically significant. However, because of limitations of sampling size due to the peculiarities of the program participants, in consideration of the limit of statistical validation exists clearly, intended to better understand the subjective experience of attendees, qualitative analyzing(qualitative research) was carried out in parallel. It was conducted a deep interview only person accepted among program participants, thematic analysis, subject analysis tasks to be subdivided by classifying by considering the semantic units of what participants expressed, was thus carried out. It found that the degree of melancholy feeling of mental disorders who participated in the Upright Body Typed Exercise Program was reduced. The course of the experience of change in depression appered the three subjects and six sub-themes such as "the start of the change", "interest of the program", "recognition of the need of the body’s health", "physical health promotion", "recovery of physical function", "negative change of habits (attitude)", "reduction of sense of depression", "confidence that it is possible to", "hope for the future". Therefore, upper body type exercise is much helpful in lung capacity and mental health of people with mental illness. So, this type of exercise mostly needed in the people with mental illness group than the other group for the quality of life.

The purpose of this study is to examine the relationship between the content areas and competencies of the Family & Consumer Sciences National Standards(NSFCS 3.0) of the U. S. and UNESCO Global Citizenship Education(GCED). For this purpose, the global perspective, content areas and competencies in NSFCS 3.0 and the keywords related to the three areas of content areas of UNESCO GCED were analyzed. Specifically, the content standards and competencies related to the words 'world' or 'global' were extracted and their relationship to the GCED topics and keywords were analyzed. The results of the study are as follows. First, NSFCS 3.0 described the direct correlation between individuals and the world by recognizing individuals as global citizens in 14 areas except for 'interpersonal relations' and 'parenting', specifically using the keyword of 'world' in content standards and competencies. Second, in the content standards and competencies of NSFCS 3.0, the keywords related to the topics of GCED areas were presented evenly in the three areas of FCS, dietary habits, family life, and human development. The social and emotional areas were not presented in clothing, housing, and consumer life. On the other hand, the behavioral area, which is emphasized most in the GCED, is presented in all the FCS content areas. From this, it is apparent that the learning field for GCED may be considered as the area of life pursued by the home economics curriculum. The results of this study provide foundational bases for understanding the relationship between NSFCS 3.0 and the GCED, and implications as to how to implement the content of the GCED in the next revision of the national home economics curriculum of Korea.

We survey recognition of nutrition labeling on the processed foods for the college students with distinction of sex and their major. The frequency of purchase that processed food is over the 3-5 times in a week. The man students preferred to have Ramyon, milk and milk products and the woman students' ingested snacks, soft drinks and sugar snacks. For another, the food major students like to have juice, soft drink, milk and milk products. Then again, the non-food major students ingested Ramyon, snacks and sugar snacks. The woman students and food major students show higher recognition of nutrition labeling and confirmation of it. The man student replied reason why to confirm nutrition labeling is to keep their health. But the woman students show interest to confirm nutrition content. The food major students confirm the nutrition labeling to determine the nutrition labels. The non-food major students did not confirm the nutrition labeling because they think it is an involved style. For knowledge of nutrition contents, the woman student and the student majoring food are well informed. But, all of the student show poor knowledge for staple foods, nutrient function and vitamin. As the research results, we suggest that the educated the student nutrition knowledge for nutrition labeling on the products. It helps to improve their dietary life and eating habits. And they can avoid buying of the processed foods by habit without confirmation of the nutrition.

The diet composition of whitespotted conger, Conger myriaster was studied using 129 specimens collected in the coastal waters Geoje, Korea from June 2018 to May 2019. The size of the specimens ranged from 11.5~22.9 cm in preanus length (AL). C. myriaster was a piscivore that consumes mainly pisces such as Engraulis japonicus and Gobiidae (%IRI: 98.4%). Of the fish species E. japonicus was the most preferred prey. Based on these results, it is considered that Conger myriaster has a characteristic of feeding on abundant prey organisms in the study area. The dietary compositions of C. myriaster was not significantly different among size classes. These results are considered to be due to a lack of specimens and the various size groups were not collected. Based on these results, it is thought that immature fishes inhabit the coast of Geoje. As body size of C. myriaster increased the mean weigh of prey per stomach (mW/ST) tended to increase (one-way ANOVA, P<0.05).

This study was accomplished to investigate the prevalence of obesity among the 229 elementary school children(boys; 115 persons, girls; 114 persons) during 4 years by retrospective study. The results were as follows; 1. The mean height and weight of 229 subjects were 143.2cm(boys;143.4cm, girls; 142.7cm), 38.8kg(boys;40.4kg, girls;36.9kg), respectively. And other anthropometric body index such as the mean BMI, Rohrer Index, WLI and Obesity Index of subjects were 18.8(boys;19.5, girls; 18.0), 1.31(boys;1.36, girls; 1.26), 115.5(boys;121.4, girls; 108.9) and 110.6(boys;114.5, girls; 106.7), respectively. 2. The mean percentile values of height and weight of subjects were higher than the '85 Korean Children's Growth Standard, respectively. In the case of boys, the 75th percentile value of weights was larger than that's 97th's. And in the case of girls, the 75th percentile value of weights was equalled to the that's 90th's. 3. When the subjects were classified into 4 groups such as obese, overweight, normal, and lean groups according to Obesity Index, their percentages were 28.8%(boys; 38.3%, girls; 19.3%), ll.8%(boys; 9.6%, girls; 14.0%), 50.7%(boys; 47.0%, girls; 54.4%) and 8.7%(boys; 5.2%, girls; 12.3%), respectively. And only I person(3.3%) is classified into normal group and 2 persons(6.7%) are classified into overweight group when they become 5 grade among 30 persons(13.1%) who were classified into obese group when they were I grade. 4. Changes in percentage of subjects differentiated by 3 indices during 4 years(from I grade to 5 grade) were as follows; In the case of BMI were 5.2%, 5.2%, 11.8%, 21.0%, 27.5%. In the case of Roher index were 13.1%, 11.8%, 14.4%, 14.8%, 17.8%. And in the case of WLI were 15.7%, 21.6%, 29.5%, 32.2%, 36.7%. 5. There was no significant difference among 4 groups on the skip rate of breakfast(obese;48.5%, overweight;55. mean meal time of subjects took about 10 minutes which was short, and the eating rate of obese group was significantly shorter than that of other groups(p<0.05). There was a tendency that the rate of the obese or overweight group eating together in breakfast and dinner was lower than that of normal or lean group. The mean T.V. watching time and the rate of eating out of subjects were 1-2 hours/day and 1 or 2 times/week. In conclusion, the subjects have been grown remarkably compared to the '85 Korean Children's Growth Standard, especially boy's weight. In order to the elementary school children to be grew as healthful citizen they should recognize the importance of meals of everyday, the balanced meals, and desirable eating habits. In addition to these, we should educate the ways of meal-life to them. We also are in need to develope the methods of education for the students themselves and their parents so that could prevent the increase rate of obesity.

Objectives: This study was performed to identify the current barriers of obesity management for children using Community Child Care Centers and their caregivers (parents and teachers working in the Centers). Further, this study explored the possibility of utilizing a mobile phone application for tailored obesity prevention and management programs to overcome the current difficulties associated with children's obesity management. Methods: The qualitative data were collected through in-depth interviews with 20 obese and overweight children or children who wanted to participate in this study using Community Child Care Centers, 12 teachers working at the Centers, and a focus group interview with five parents of children using the Centers. Data were analyzed with a thematic approach categorizing themes and sub-themes based on the transcripts. Results: The current barriers of obesity management of obese and overweight children using Community Child Care Centers were lack of self-directed motivation regarding obesity management (chronic obesity-induced lifestyles and reduced self-confidence due to stigma) and lack of support from households and Community Child Care Centers (latchkey child, inconsistency in dietary guidance between the Center and household, repetitive pressure to eat, and absence of regular nutrition education). Mobile phone applications may have potential to overcome the current barriers by providing handy and interesting obesity management based on visual media (real-time tracking of lifestyles using behavior records and social support using gamification), environmental support (supplementation of parental care and network-based education between the Community Child Care Center and household), and individualized intervention (encouragement of tailored and gradual changes in eating habits and tailored goal setting). It is predicted that the real-time mobile phone program will provide information for improving nutritional knowledge and behavioral skills as well as lead to sustainable children's coping strategies regarding obesity management. In addition, it is expected that environmental factors may be improved by network-based education between the Community Child Care Centers and households using the characteristics of mobile phones, which are free from space and time constraints. Conclusions: The tailored education program for children using Community Child Care Centers based on mobile phones may prevent and reduce childhood obesity by overcoming the current barriers of obesity management for children, providing environmental and individualized support to promote healthy lifestyles and quality of life in the future.

In this study, 60 seniors aged at least 65 years who attended C Senior College in Daegu were selected and randomly allocated to test and control groups of 30 subjects each. The Clean Diet Program was only applied to the test group, and the differences in self-efficacy, depression, health behavior, subjective perception of health, wellness, and physiological indices (blood pressure, blood glucose levels, hyperlipidemia, and BMI) between the test and control groups were compared. The results show a significant difference in the test group exhibiting improved or mitigated self-efficacy (t=6.003, p<.001), depression (t=4.038, p<.001), health behavior (t=6.196, p<.001), subjective perception of health (t=6.624, p<.001), and wellness (t=7.069, p<.001). Among the physiological indices, there was a significant decrease in BMI (t=5.974, p<.001). The results demonstrate the mediation effects of the Clean Diet Program. Since the Clean Diet Program can be implemented through walking, simple exercises, and eating habits, it provides great economic efficiency and usefulness and provides a very reasonable intervention program for the elderly. Based on the results, we discuss how to improve the elderly's attitude toward health promotion and their quality of life.
