The diet of the walleye pollock Gadus chalcogrammus, was studied by examining the stomach contents of 864 individuals. Using gill nets, samples were collected monthly from January to December 2017 in Jugwang, Sokcho, Yangyang, Uljin, Ganggu, and Gampo, Korea. The specimens ranged in total length (TL) from 16.6 to 75.2 cm. G. chalcogrammus fed mainly on Euphausia pacifica (Euphausiacea) and less on Cephalopoda, Pisces, Mysidacea, and Macrura. The results indicated that G. chalcogrammus is a specialist feeder, feeding mainly Euphausiacea. With growth, however, its diet shifted from Euphausiacea to Cephalopoda, Macrura and Pisces. Smaller individuals (<40.0 cm TL) consumed mainly Euphausiacea. The proportion of Euphausiacea decreased with increasing body size, whereas the consumption of Cephalopoda and Macrura increased gradually.

Recently, childhood obesity is increasing in Korea mainly due to westernized dietary pattern. The purpose of this study is to investigate diet pattern(habit and behavior), nutritional knowledge and taste favor in normal and obese children. We carried out anthropometries and self questionaire about life style among the 5th-grader in elementary school(88 boys, 102 girls) in Seoul. The results are as follows : Physical conditions are boys’average hight and weight 142.0cm, 37.5kg ; and girls’143.7cm, 35.6kg. BMI are normal group 38.7% and abnormal group 61.3%(obese 24.2% underweight 16.1% overweight 14.0% very underweight 7.0%) A great part of obese children live in apartment house(79.5% of obese children in southern Seoul; 60.2% in northern Seoul). Obese parents have obese children. Diet behavior, diet pattern, food habit and food preferance of children are similar to their parents, especially their mothers. Preferance in taste of children follows in order of hot, sweet and mild. Especially obese children favor sweet taste more than others. The 61% of them are interested in weight control. Their nutritional knowledges are poor(4.9/10). They like more westernized food(hamberger) than korean food(In-jul-me).
This study was to suggest the roles of social enterprises in maintaining healthy life of the socially vulnerable by creating a customized care environment through chronic disease diet management targeting the elderly at home in need of care in the community. As for the subjects of this study, 102 in-home elderly people aged 65 or older (14 males & 88 females) who needed care in the community were provided with a diet management lunch box delivery service customized for chronic diseases. Theoretical education and cooking class on chronic diseases were provided to 15 volunteers with 10 sessions, and customized lunch boxes were provided to the elderly with chronic diseases at home on that day. In conclusion, it is believed that only by increasing the level of knowledge about chronic diseases and nutritional knowledge of the elderly will it be possible to establish a proper meal plan. Since the role of volunteers is important, it is necessary to systematically seek nutritional education methods for volunteers.
Atopic dermatitis (AD) is believed to be associated with the intake of antioxidant nutrients and fatty acids due to its immunological dysfunction. The purpose of this study was to examine the effects of nutrition education promoting vegetable, fruit, and fish intake on the severity of AD in children. Children with AD aged 6 months to 5 years were randomly assigned into education and control groups, and followed for 1 year. Seventy-six children completed the study (38 for control, 38 for education). The education group received education promoting the intakes of antioxidant-rich foods (vegetables, fruits) and n-3 fatty acid foods (fish). A 24-hour food recall was collected for the diet information. After education, all vegetables (p < 0.001), fruits (p < 0.01), and fish (p < 0.05) intakes per 1000 kcal increased significantly in the education group, whereas only vegetable intake increased in the control group (p < 0.001). The SCORAD index, the severity of atopic dermatitis, decreased significantly in the education group (p < 0.05). Increased consumption of dietary vitamin E was significantly associated with reduction in the SCORAD index, after adjusting for age and gender (p < 0.05). A nutritional education program to increase vegetable, fruit, and fish intake may be effective in reducing the severity of AD, and vitamin E intake may be associated with the decreased severity of AD. More controlled studies on the relationship between these intakes and severity of AD, with intensive diet and/or supplement intervention programs, are needed to obtain conclusive results.
This study was designed to develop, implement and evaluate a nutrition education program for elementary school children. Subjects consisted of 47 children in the 6th grade in Seoul, Korea. They received five sessions of nutrition education from June to July, 1999. Topics for nutrition education included function of nutrients, food sources of nutrients, balanced diet, meal planning, and adequate energy intake. Each session lasted 40 minutes. To evaluate program effectiveness, one group pretest-posttest design was used. Subjects were given a pretest and a posttest on nutrition knowledge, eating attitudes, eating behavior, and dietary intake. All data were statistically analyzed mainly using the paired t-test and $\chi$$^2$-test. There was a significant difference between pretest and posttest score on nutrition knowledge(p<0.001), subscales of nutrition knowledge including food sources of nutrients, function of nutrients, and balanced diet(p<0.001). These changes in nutrition knowledge were also shown both in boys(p<0.001) and in girls(p<0.001). Eating attitudes, subscales of eating attitudes, and eating behavior were not significantly changed after nutrition education, although some changes were observed in these variables. Dietary intakes were not significantly were not significantly changed after nutrition education for all subjects ; however, different patterns in dietary intakes were observed when examined by sex. There was an increase in nutrient intakes among boys, while there was a significant decrease in nutrient intakes among girls after program implementation. Especially, it was noted that girls had diets deficient in iron, calcium, and vitamin A, even after nutrition education. It was concluded that a five-week nutrition education program can improve nutrition knowledge or some dietary intake, but this might not be enough to induce changes in food attitudes, eating behavior or dietary intakes. It might be necessary to incorporate diverse approaches, targeting sub-groups of children, and follow-up in nutrition education for elementary school children.

This study aimed to develop, and evaluate the effectiveness of, a home economics dietary education program that could be used to improve high school students' sustainable dietary competencies. To achieve this goal, learning objectives and elements were selected for the education program to improve the students' sustainable dietary competency. The content validity of this program was verified with numerous experts. After implementing the new educational program, its effect on high school students' sustainable dietary competencies was assessed through pre- and post-tests. The results of this study are summarized as follows. First, through the textbook analysis, the necessity of developing an educational program that can cultivate the three areas that constitute a sustainable diet (environment, health, and consideration) was confirmed. Second, a total of nine teaching and learning plans for sustainable dietary education programs were developed. From there, content validity verification was conducted by experts, indicating that the developed educational program was highly applicable in the field. Third, after the implementation, a survey was conducted based on a questionnaire consisting of 20 items related to three areas of sustainable diet, while the pre- and post-test assessment indicated statistically significant differences in all three areas: environment (pre: 3.40, post: 4.46, p<.001), health (pre: 3.15, post: 4.32, p<.001), and consideration (pre: 3.46, post: 4.48, p<.001). It is expected that the educational program developed in this study will be used as a basis for dietary education that fosters food citizenship in high school home economics courses.
The purpose of this survey was to investigate eating habits, life styles and nutritional care of diabetic outpatients and to provide basic data for developing individualized nutritional care and diabetic education programs. This survey was carried out by nutritional counseling with a questionnaire and checking medical record. Information about the general characteristics of the subjects, eating habits, health-related life styles and attitude and perception of subjects to diet therapy was gathered from 200 randomly-sampled diabetic outpatients at a University Hospital located in Inchon. All data were analyzed by Statistical Analysis System(SAS) software. The results are summarized as follows : Female subjects were 63.5% of total subjects and 65.5% of total subjects were 50 years or more. The average Body Mas Index(BMI) of male and female subjects were 23.06kg/㎡ and 25.02kg/㎡ respectively and 44% of all subjects wee obese. Among subjects, type II diabetic patients were 81.0% and 82.5% of subjects had suffered from diabetes for more than one year. Also 41% subjects had diabetic history in their family. More than half of the subjects had nutrition education concerning diabetes. Also 75.5% of them thought that nutrition education was effective. The most important guideline in diet therapy was to eat cooked rice with dietary fiber-rich grains. Therefore, it might be necessary to develop nutrition education program adjusted according to diabetic patient's needs and life styles, which may increase feasibility of self-care and implementation of management guidelines.

Purpose: The purpose of this study was to investigate the knowledge of diabetes and insulin use in patients with type 2 diabetes. Method: Participants (139) were recruited from the endocrinology outpatient department of a tertiary care hospital in an urban city. Knowledge of diabetes knowledge was measured by a brief diabetes knowledge test which had two components: a 14-item general test and a 9-item insulin-use subscale. Result: The average scores for knowledge of diabetes and insulin were 62.4 and 41.8 respectively. Scores were lower for items on the definition of glycosylated hemoglobin, diabetic diet, signs of ketoacidosis, and insulin reaction compared to other items. Knowledge scores were significantly lower for older participants, those who had lower levels of education, those who did not have a spouse, those who did not have a job, those who were not being treated with insulin, and those who tested their blood glucose less than 3 times a day. Conclusion: Definition of glycosylated hemoglobin, diabetic diet, signs of ketoacidosis, and insulin reaction should be included in education for patients with type 2 diabetes. Special education programs should be developed for elderly people, those with low levels of education those without a spouse, or without a job, or who are not being treated with insulin.

This study was designed to assess the needs for nutrition education and educational materials for older adults. Two cross-sectional surreys were conducted. The first survey, conducted by personal interviews, was part of the large-scale elderly nutrition study. Subjects were adults aged 50 and over, recruited from 6 large cities and 8 middle-sized cities(n = 1,850). The second survey, done by mail survey using open-ended questions, was conducted with dietitians working at public health centers or hospitals(n = 53). Adults aged 50 and over were interested in topics such as healthly eating(32.1%), hypertension/stroke and diet(22.1%), osteoporosis and diet(11.4%), and diabetes and diet(9.2%). Television and radio(58.2%), health professionals(12.2%) and friends(7.9%) were common sources of nutrition information. Preferred topics of nutrition education and sources of nutrition information were different by general characteristics of subjects, suggesting that nutrition education or educational materials be planned considering the characteristics of subjects. About 70% of subjects indicated that they sometimes use or do not use nutrition information in daily lives, suggesting the need to provide more practical information. Among 53 facilities responding to the second survey, 73.6% provided nutrition education for older adults. Common topics for nutrition education included diabetes(39.3%), hypertension and stroke(19.1%) and general nutritional management(11.2%). These were consistent to the topics preferred by older adults. As materials In elderly education, dietitians wanted primarily to use leaflets and slides. Boards, booklets and posters were other commonly cited materials. For contents of elderly educational materials, dietitians mentioned the nutritional management for age-related diseases(33.8%), general nutritional management for older adults(25.4%) and practically applicable information(19.7%). They also suggested that nutrition education materials for the elderly should use larger print and attractive pictures, and be easily understood, as well as presenting simple, specific and practical information. These results provide baseline information for developing nutrition education and educational materials for older adults.
The chemical components in plant cuticular wax can be used as markers to estimate the species composition of the diet of grazing animals. In this experiment, composition of the diet of yak on the Qinghai-Tibetan plateau was estimated using n-alkane analysis. During the grazing period, samples of whole plants of the species present, plus fecal samples voided by the yak, were collected, air-dried and ground prior to the extraction of cuticular wax n-alkanes. The species composition of the yak diets was estimated by relating fecal alkane contents to those of the plant species, using the 'ATWHAT'software package. The results showed that the n-alkane technique can detect the main dietary components selected by yak. The diet consumed by yak contained 33% Kobresia humilis, 67% Stipa aliena in summer pasture; 26% Potentilla anserine, 74% Carex qinghaiensis in autumn pasture; 52% Carex qinghaiensis, 32% Heteropappus bowerii and 16% Saussurea semifasciata in winter pasture and 5% Carex qinghaiensis, 95% Achnatherum splendens in spring pasture. The apparent selection for forbs is likely to be a reason for nutritional constraint of yak inhabiting alpine environments.
