The otitis media has the highest rate of occurrence in 6-36 month after birth, and relatively high rate of occurrence to six years old. It is one of major cause for hearing loss problem because of its high rate of recurrence. The researcher observed at bed that feeding posture and feeding habit at night have some relationship with occurrence of otitis media. I found that medical research in this area was very weak, and it caused her to concentrate her research on the topic. This paper was undertook a retrospective case-control study to find out the relationship between the mode of feeding and the occurrence of otitis media among the otitis media patients and the healthy persons. As the controling groups, the researcher chose fifty eight mothers whose children received the treatment of otitis media(6-36 months after birth) from the pediatrics clinic of two general hospitals in Seoul, as the patient group, and forty five mothers who consulted with their child to well baby clinic at the general hospital and kindergarten in Seoul as the control group. The results of the survey can be summarized as followed : 1. "Otitis media patient group may have more lying posture mothers while feeding than the healthy control group". The first hypothesis is supported by the fact that the children who have lying posture feeding habit mothers are more easily exposed to otitis media than those who have sitting posture feeding habit mothers as the analysis show : $X^2=8.142$, p = .017 2. "Otitis media patient group may have higher rate of sleeping habit with milk bottle on the month at night than the healthy control group does". The second hypothesis was supported by the fact that the patients group has higher rate of expected sleeping habit than the healthy group dose as the analysis show : $X^2=4.35$, p = .037 3. "Otitis media can be found more in the artificial feeding group than in the healthy children group". The hypothesis is rejected by the analysis, $X^2=1.550$, p = .416. Though the hypothesis is not supported by this research, we need to encourage mothers to feed mother's breast milk on the ground that healthy group has mother's milk feeding tendency, and the best food for infants is their mother's milk, and psychological-sociological effects of breast feeding os quite good for children. It will improve the health of infants. It can be summarized as follows : Otitis media is more concerned with posture of feeding and night feeding habits than feeding modes. On the basis of this survey, feeding education problem for mothers of infants need to be developed. In the education, sitting-embracing posture of feeding, mother's breast feeding, and prohibition of children's lying posture feeding at night need to be emphasized.

The purpose of this study was to investigate the prevalence of severe early childhood caries and feeding pratices in preschool children. The subjects of study were six hundred and seventy-two preschool children in Iksan city. Severe early childhood caries(S-ECC) was defined as the presence of one or more cavitated, missing due to caries, or filled smooth surfaces in primary maxillary anterior teeth. The caregivers of children were given a questionnaire including age, gender, birthweight, and feeding practices. The prevalence of S-ECC was 34.5%. The prevalence was significantly higher when there were the habit of sleeping while feeding, the habit of feeding sour or sweet content in the bottle, and the habit of using the pacifier. Birth weight, breast-feeding, bottle-feeding, and the sippy cup habit showed no significant association with the prevalence of S-ECC. There were significant positive associations between breast-feeding and sleeping while feeding, between bottle-feeding and the pacifier, between sleeping while feeding and sour or sweet content in the bottle, between sleeping while feeding and the sippy cup, between sleeping while feeding and the pacifier, and between the sippy cup and the pacifier. There were significant negative associations between breast-feeding and the pacifier.

This study was conducted to investigate to the effect of weaning food-feeding methods on Preschool-Children's food habit, food preference and iron nutritional status for the subjects of 337 children, aged 18-60 months attending day care centers in Suwon and Seoul area. It divided the subjects into two groups according to the weaning food-feeding methods during their weaning period. One group(spoon-group) was defied as one had used to spoon over two times a day for 5 months and the ohter group (bottle-group) as one had used to bottle over two times a day for 5 months in weaning periods. All of the data were analyzed based on the weaning food-feeding method, mainly using bottle or spoon during their weaning period. The study results are summarized as follows. 1) 44.2% of the mothers mostly used bottle and 46.6% of them mostly used bottle to feed weaning foods. Age difference between the two groups was not found. 2) The numbers of daily consumed foods were significantly more higher in the spoon-group than the bottle-group and the amount of daily milk consumption was more higher among bottle-group. 3) Both of food intake frequency and food preference scores of the spoon-group were significantly higher than food intake frequency and food preference scores the bottle-group. 4) Iron nutritional status assessed by Hb and Hct was low in general. Only 26-63% of the subjects at each monthly age were in normal range. The higher the children's age, the more were grouped in normal range, which was more evident among children of the bottle-group. 5) Mother's nutrition knowledge related to weaning was more higher among spoon-group than both-group. There results shows the importance of appropriate weaning food-feeding methods for Preschool-children's food habit, food preference and nutritional status especially iron nutritional status. Nutrition education for mothers with weaning aged children has to be stressed and related programs have to be intervened effectively.

To investigate the prevalence and etiologic factors of nursing caries, oral examination was performed on 1,100 kindergarten children from 6 Seoul areas and 3 Hongchun areas. Parents were asked to fill out questionnaires. The following results were obtained: 1. The prevalence of nursing caries among 1,100 in the sample group(age 30-75 months) was 14.8%. 2. Fathers' education level(p<0.05), mothers' education level(p<0.01) and monthly income was higher in caries-free group children. 3. When the dietary tendencies of nursing caries group and caries-free group were compared, no significant differences in the length and method of feeding were found. However, nursing caries group showed higher frequency of bedtime nursing habit(p<0.01), daytime use of bottle as a comforter(p<0.01) and other beverage feeding in addition to milk(p<0.01). 4. When the parents' awareness of caries prevention was compared, caries-free group per formed more frequent tooth cleansing(p<0.05) and periodic dental examination(p<0.01).5. Dental caries experience of mothers was significantly lower in the caries free group(p<0.05). From the above results, it can be concluded that deleterious nursing habit had great effect on developing nursing caries and the incidence of nursing caries was lower among children with parents of higher socioeconomic status.

To analyze the mode of inheritance of this gene in Fb strain, carried out cross experiment between Fb and several Japanese and Chinese origin strains. The results of crossing experiments, feeding ratio in F1 hybrids were nearly the mid of parents, F2 and backcrossed hybrids(BF1) were approximately intermediate between Fb and other strains. Hence, the feeding habit of cabbage leaves on Fb strain is assume to be incomplete dominance.

Studies were carried out to report breeding procedure and characteristics of Fb, a strain of silkworm with abnormal food habit polyphagous. Selection was continued up to the 14th generation toward higher incidence of cabbage leaves feeding variants. In the autumn of 1992(7th generation), selected strain were subjected to severe selection by feeding them on artificial diet that did not contain mulberry leaf powder. The results were clearly positive and reached to higher than 95% of cabbage feeding in the 14th generation. This strain was first discovered by feeding cabbage leaves, but later they were observed to eat some kind of plants like lettuce, Chinese cabbage, radish, beet, apple, persimmon, pear, etc. As described above the procedure, cabbage feeding trait was clearly heritable. The strain responsible for this traits was named Fb.

Feeding habits of Gobiobotia brevibarba were investigated at Hongcheon River of Bangokri, Seomyon, Hongcheongun, Kangwondo from January to December, 2000. G. brevibarba was a carnivore and consumed mainly Ephemeroptera, Tricoptera and Diptera. Small quantities of Plecoptera and Coleoptera were included as a minor food items. The species showed ontogenetic changes in feeding habits. Individuals of small size (21~50 mm SL) fed mainly on small prey organisms such as Diptera and Ephemeroptera. However, larger Tricoptera were heavily selected with increasing fish size. The relative proportion of these food items changed with season. The prey selection indices for Ephemeroptera were positively selected in spring, summer and autumn, and negatively selected in winter, Diptera were positively selected in March, October and November.

We investigated the feeding habits of Rhynchocypris kumgangensis in Hongcheon River of Saenggokri, Seoseokmyeon, Hongcheongun, Gangwon-do, Korea from April 2002 to March 2003. The fish is korean endemic species upper streams in Korea. It was asscertained that R. kumgangensis is a carnivore and consumes mainly Ephemeroptera, Diptera, Terrestrial insects and Trichoptera. The most important prey was chironomids: Chironomus sp. Their feeding habits changed according to growth. Small fish fed mainly on small prey organisms such as Diptera, while larger fish fed much more on Ephemeroptera and Terrestrial insects. There were also seasonal changes in the relative proportion of their food items.

In this study was made a survey of the dietary habit with too many likes and dislikes (one-sided dietary habit) of first grade primary school children on 1098 primary school children, in an attempt to provide data for an efficient nutrition management for children. The results of the survey were interpreted in term of the standard of education and the state of employment of the children's mothers, the standard of living, sex, the number of sibling, the order of birth, whether or not living together with grandmother, and the breast feeding period. From the results of this study it seems that the overprotection by mothers leads the children to one-sided dietary habit. The mothers listed the lack of nutrition knowledge and the lack of efforts for meal management as major reasons for that they failed to help their children form a good dietary habits.

Habitat, reproduction and feeding habit of endangered fish Koreocobitis naktongensis from Jaho stream, Gyeongsangbuk-do, Korea were investigated from March 2010 to June 2011. This species inhabits at the upper and middle parts of stream, which were composed of cobbles and pebbles bottom. The current velocities in these microhabitat were 5~10 cm/sec and depth were 50~110cm. The sex ratio of female to male was 1 : 0.92. It is presumed that the spawning season is from May to June when water temperatures were 17 ~ 20$^{\circ}C$. The average number of mature eggs in ovary were about 22,643 (15,909~30,323), mean egg diameter was 0.87${\pm}$0.05mm. K. naktongensis fed mainly on Chironomidae (IRI, 72.0%) and Ephydridae (26.9%) of Diptera.
