The feeding habits of Okamejei kenojei were studied using 242 specimens collected from October 2010 to September 2011 in the coastal waters of Gadeok-do, Korea. O. kenojei was carnivorous feeder that consumed mainly shrimps, crabs, and fishes. Its diet also included small quantities of stomatods, cephalopods, amphipods. The size of O. kenojei ranged from 10.4 to 47.4 cm in total length (TL). O. kenojei showed ontogenetic dietary shift. <15.0, 15.0-19.9 cm size classes fed mainly on shrimps and amphipods. 20.0-24.9 cm size class fed mainly shrimps and crabs. Thereafter, shrimps and crabs were decreased with ontogenesis while fishes and cephalopods were increased. Increasing size, the mN/ST were constantly decreased, but mW/ST were constantly increased.

Objectives : This study aimed to explore the influence of food intake and oral health behaviors on dental caries in juveniles. Methods : A total of 2,129 juveniles completed a questionnaire survey to identify the presence of permanent teeth caries, behaviors relevant to oral health and food intake based on the fourth National Health and Nutrition Survey. Results : Multiple logistic regression analysis showed that higher occasions of intake of carbonated drinks significantly cased dental caries in the meanwhile oral health behavior and the number of toothbrushing was in reverse proportion to dntal caries. The risk of dental caries was higher in the group of lower frequency of toothbrushing and intake of carbonated drink. Conclusions : Carbonated drinks intake and the number of toothbrushing is closely related to dental caries. So it is very important to develop oral health education program in order to improve eating habits and toothbrushing habits in juveniles.

The Feeding habits of larval Liparis tanakae collected from the Nakdong River estuary were studied. L. tanakae [3.8-10.6 mm notochord length(NL)] was a carnivore thatconsumed mainly copepods. Its diet also included small numbers of free-living flatworms (Macrostomida), tintinnids, cladocerans, and polychaetes larvae. To evaluate ontogenetic changes in dietary composition, three size groups were designated: 3-5, 5-7, and >7 mm. Copepods were the most important prey items for all size groups. The smallest size group frequently preyed on polychaete and bivalve larvae, along with copepods. As notochord length increased, the numbers of cladocerans and Macrostomida increased relative to those of polychaete and bivalve larvae.

The feeding habits of Spanish mackerel (Scomberomorus niphonius) were studied based on the examination of stomach contents of 445 specimens collected from January to December 2004, in the Southern Sea of Korea. The size of Spanish mackerel ranged from 26.1 to 105.4 cm in fork length (FL). Spanish mackerel was a piscivorous fish which mainly consumed teleost fishes such as chub mackerel (Scomber japonicus) and anchovy (Engraulis japonicus). Its diet also included small quantities of shrimps, stomatopods, cephalopods, crabs, polychaetes, amphipods, cumaceans and copepods. Smaller individuals (<60 cm FL) consumed small fishes such as Engraulis japonicus and crustaceans. The portion of these prey items decreased with increasing fish size, and this decrease was paralleled with increased consumption of lager fishes such as Scomber japonicus and Cololabis saira. The prey size increased with the increase of fish size.

The purpose of this study was to provide basic data of nutrition education to teach the right eating habit and lifestyle by investigating eating habit of students in private and public elementary schools of Kangnam and Kangbuk region. When the eating habit was investigated, there was no difference between the residential region, and school types. Depending on gender and person who cooked, there was meaningful difference in the eating habit. When the mother or father cooked for the student, his or her child had breakfast everyday, had a meal regularly, enjoyed the meal with the family, and left less food. This shows that the meal with family is a very positive factor in the formation of right eating habit. The female students tend to eat snacks, skip breakfast, have unbalanced diet, leave food, and watch TV during a meal more than the male students. Therefore, the female students need more education of eating habit. Also, not many the students usually got corrected their bad eating habits from others, and this showed that no proper guidance of their bad eating habits was done. Nevertheless, the students tried to correct their eating habits by themselves. If the schools and students' give them the proper education about eating habit, it can be more effective. Therefore, the school should teach the students and their parents the right table manner and nutrition information through a systematical curriculum. In special cases, they should teach the students individually.

The feeding habits of the Pacific herring Clupea pallasii were examined based on 333 specimens collected from the coastal waters of the East Sea of Korea. Sampling was conducted in April, June, and September 2019 and February 2020. The total length of the C. pallasii ranged from 11.9 cm to 37.7 cm. Euphausiids (93.0%, index of relative importance, IRI), especially Euphausia, comprised the primary diet of the pacific herring, in addition to amphipods, copepods, and fishes. The dietary composition of C. pallasii showed non-significant differences by size. As body size of C. pallasii increased, the mean number of preys per stomach (mN/ST) and the mean weight of preys per stomach (mW/ST) tended to increase.

This study was carried out to evaluate the effects of supplementary diet in infants. Influence of appropriate dietary habits on infants was also examined by being applicable to diets fortified chewiness as a means of intervention. The iron supplementary diet was supported to the healthy infants twice a day for three months. Measures of hemoglobin, hematocrit, RBC count, serum iron, TIBC, ferritin, development examination, and dietary intake patterns of experimental group (n = 25) and control group (n = 20) were performed before and after the intervention. The amount of iron intake from the supplementary diet in the experimental group was $1.77{\pm}0.80 {\cal}mg/day$. After the intervention period, the experimental group not only had increased intakes of grains also decreased intakes of milk. Outcomes observed in infants receiving iron intervention showed that the improved trend of excessive milk intakes and the possibility as a regular diet by serving the iron supplementary diet which can apply to main dish. All measures in blood did not provide significant differences except TIBC between the experimental and the control group before the intervention. But, after the intervention, the experimental group improved most levels of measures, especially significance in hemoglobin, but serum iron. Development of two groups did not differ significantly and both groups were in the range of normal infants' development. However, the levels of MDI and PDI evaluated by BSID-II in the experimental group were slightly higher than the control. Furthermore, the development of cognitive and languistic function was associated with infant growth in the experimental group. In conclusion, this research demonstrated that the iron supplementary diet could affect the iron status and the development of infants despite low-dose supplementation of iron.

It is suggested that evaluation of diet quality may be a great indicator of nutritional assessment. The aim of this study was to evaluate the diet quality of children and adolescents based on nutrient and food group intake and Diet Quality Index-International (DQI-I). This survey was conducted through questionnaires and diet record survey to 477 students (elementary school students; n = 131, middle school students; n = 136, and high school students; n = 210). The results showed that high school students were significantly more often to skip breakfast compared with the other groups. The middle and high school students consumed significantly higher intakes of food and energy compared to the elementary school students. Also the number of nutrients in Index of Nutritional Quality (INQ) < 1.0 of high school students were significantly higher than that of elementary and middle school students. The Korean's dietary diversity score (KDDS) of elementary school, middle school and high school students were 4.1, 4.4 and 4.3 respectively. The average DQI-I of elementary school, middle school and high school students were 66.7, 65.5, and 63.7, respectively and there was significant difference. Also, middle school students showed to have higher score in variety and adequacy category compared with the other groups, and elementary school students appeared to have higher score in moderation category. In conclusion, high school students appeared to have unhealthy dietary habits in terms of high frequency of skipping breakfast and lower INQ and DQI-I score compared to the elementary school and middle school students. Therefore, the proper dietary management should be needed for high school students.

For the purpose of carrying out nutrition counseling effectively and efficiently, this study assessed the nutrition counseling practice, perception and nutrition knowledge of elementary school children in Gyeongbuk province. Survey questionnaires were distributed between November 2009 and December 2009 to 100 nutrition counseling experienced children (participants) and 110 nutrition counseling non-experienced children (non-participants) and were completed with nutrition teachers' assistance. According to the survey results, girls and overweight/obese children showed higher tendency of participation in nutrition counseling (p<0.001). Participants who took nutrition counseling according to their own intentions showed satisfaction after counseling on diverse subjects such as obesity, unbalanced diet, and weight control. Particularly, 'lack of counseling session time', 'unfavorable counseling condition' or 'difficult explanation' caused participants unsatisfaction after counseling. Participants usually perceived the meaning of nutrition counseling more correctly than non-participants and showed positive intentions for taking further counseling in the future(p<0.001). Diet good for weight control, good food to fix unbalanced diet and diet good for growing stature were the top three subjects of nutrition counseling chosen by subjects (p<0.001). Participants also showed higher nutrition knowledge scores than non-participants. Therefore, it is critically important to apply nutrition counseling in the proper environment (counseling room, time, teaching materials, etc) to elementary school students to fix healthy food habits. Therefore, nutrition teachers need to be provide professional nutrition counseling skills and knowledge.
