The propose of this study was to investigate taurine intake in formula-fed and breast-fed infants and to estimate the level of taurine of blood and urine in order to determine the requirement of taurine intake in infants. These results will be useful to suggest the guideline of requirement of taurine intake and may contribute toward the proper use of breast milk substitutes. Experimental groups were breast-fed infants (n=10) and formula-fed infants (n=10) of 20 normal delivery infants in general hospital. This study was longitudinal study from birth up to 16weeks (0 week, 4 weeks, 8 weeks, 12 weeks, 16 weeks). The items of test were anthropometry(weight, height, head circumference, chest circumference), intake of taurine, taurine level of blood and urine in breast-fed and formula-fed infants. There were no significant differences between breast-fed and formula-fed infants in weight, height, head and chest circumference. There is a need for future studies of exclusive infants with larger samples to determine which growth pattern should be considered as the norm. Taurine concentration of plasma and urine did not differ between breast-fed and formula-fed infants. Taurine intake recommendations for infants is about 30mg/day from this study. This data will be useful for production of human-like formula milk and suggestion of an index of selection of a consumer in taurine.

The purpose of this study is to first discriminate and assess those infants who appear healthy in appearance but who could face possible risk factors in the future and, secondly, to identify those infants who may have difficulties in their developmental stages. The subjects of this study consisted of 35 full-term infants (39-40 weeks) and 33 pre-term infants (34-35 weeks). The infants' voices were recorded for three minutes, for which EDIROL by Roland and a stand-type microphone made by SONY were used. This was done to discern the value of the Breath unit (B-unit) and the fundamental frequencies ($F_0$). It was found that there were significant differences in terms of F0 since the pre-term infants had higher F0 than the full-term infants, showing a result of 436.4 Hz for the full-term infants and 460 Hz for the pre-term infants (p<.05) There was an average rate of 4.01 for the full-term infants and 4.02 (SD=1.69) for the pre-term infants in shimmer. For NHR, it was observed .44 for the full-term infants and .50 for the pre-term infants, thus revealing no significant differences in these observations. This study shows that the crying of newborn babies is related to their physical conditions and it is a sensatory response to these conditions. Furthermore, this study could be helpful for the early detection and measurement of newborn babies who look clinically healthy but could be at risk through acoustic and physiological analyses.

The purpose of this study was to compare the temperamental differences between the normal infants and low-birth-weight infants. The subjects of this study were 70 mothers with normal infants and 62 mothers with the low-birth-weight. Convenient sampling was done at three regions. The infant temperament scale developed by Pridham & others (1994) was used. Data were analyzed by SPSS WIN program. The results were as follows; 1) There was a significant difference in total temperament score between the low-birth-weight infants and normal infants. The scores of the low-birth-weight infants were significantly lower than those of normal infants in the subscales of amenability and persistence, activity, and reactivity. In adaptability, there was no significant difference between two groups. 2) In both groups, there were no significant difference by socio-economic status of parents, delivery type, and birth order. But, in the case of low-birth-weight infants, the temperament score of infants over 6 months was significantly higher than that of infants under 6 months. 3) In the correlation analysis among subscales of the temperament, amenability and persistence, activity, and reactivity showed the significant relationship. But adaptability showed significant correlation only with the amenability and persistence. In conclusion, temperament score of low-birth-weight infants were significantly lower than that of normal infants. It was suggested that parenting education for low-birth-weight infants would be needed to understand and impact the positive infant temperament.

Objectives: The purpose of this study was to investigate the factors affecting the use of oral hygiene products in infants. Methods: From October 2015 to December 2015, astructured questionnaire survey was conducted for infants and parents about the infants' oral hygiene product use from 0 to 4 years of age in Seoul and other metropolitan areas. Results: The use of oral tissues for infants and children was more frequent in infants, with less than four uses of oral tissues per 10 infants. The overall amount of toothpaste usage among infants was lower than those of infants whose parents are high school or college graduates. The number of oral tissues used per infant per week was less among infants who sucked less than 4 times per 10 infants. The frequency of use of infant mouthwash per week in every 10 infants was less than those who swallow mouthwash less than once. The number of mouth rinses after the use of oral tissues for infants was high in boys, and the number of infants who sucked oral tissues was less than 4 times when used 10 times. The number of mouth rinses after the use of toothpaste was less for infants with college-graduate parents. The factors affecting the number of mouth rinsings after using oral tissues for infants were gender and sucking frequency. Conclusions: In this study, the oral hygiene products for infants were found to differ and affect the usage, the frequency of use, and the number of mouth rinses according to the general characteristics of infants' and parents and the use of oral hygiene products.

One- to three-month-old infants (n=232) were compared their upper arm cumference and skinfold thickness(triceps, subscapular) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). As reported previously, weight, length, head and chest circumferences of these infants were good, and overall growth status was not significantly different by feeding methods, but weight, weight velocity and chest circumference of formula-fed infants were higher than breast-feds at 3month, significantly. Hear, the triceps skinfold thickness of infants at 1, 2, and 3 postpartum months were 7.4, 9.5 and 10.5 mm, respectively. The triceps skinfold thickness of breast-fed infants were higher than formula-feds at 1 and 2 postpartum month, but at 3 month that of formula-fed infants was greater than breast-fed infants, insignificantly. The subscapular skinfold thickness of infants were 6.4, 9.2 and 10.6 mm at 1 to 3 postpartum months, respectively. The upper arm circumference of infants were 11.7, 13.4, 14.3cm, and the arm muscle diameter were 34.5,39.3 and 41.7cm at one to three postpartum months, respectively. The upper arm circumference of male infants was higher than females at 2, 3 postpartum months. Overall, there were no signifiant differences between feeding methods in triceps and subscapular skinfold thickness, upper arm circumference and arm muscle diameter. But 3-month-old formula-fed male infant showed bigger significantly in arm circumference than the breast-feds. From this survey, long-term survey on growth and body composition of large scales might be necessary to determine the effect of feeding methods of infants after 3 months and to set proper body composition standard for infant.

The purpose of this study was to examine the effect of treatment when the V{\ddot{o}}jta therapy applied to the infant with central coordination disturbance in early stage. The subject were 10 cases : each one with the V{\ddot{o}}jta therapy applied to the group of the infants before 6 months old and the group of the infants over 6 months old. When the V{\ddot{o}}jta therapy was applied I analized the papper which was written about the infants who were diagnosed as moderate CCD and divided two groups which were the infants before 6 months old and the infants over 6 months old. These collected data were analyzed by using t-test. The results of study were as follow; 1. When I compared the locomotion stage after the V{\ddot{o}}jta therapy. t-test showed significant differences. The group of infants before 6 months old had the result 7 to over stage 7 and the group of infants over 6months old had the result 2(p<.05). 2. When I compared the result of the postural reaction after the V{\ddot{o}}jta therapy, 1-test showed significant differences. The group of infants before 6 months old had 6 cases was normalizes and the group of infants over 6 months old had 1 case was normalized(p<.05). 3. When 1 compared the duration of the V{\ddot{o}}jta therapy between the group of infants before 6 months old and the group of infants over 6 months old. t-test showed significant differences. The group of the infants before 6 months old had 5 cases for 1-6 months and 4 cases for 7-15 months, 3 cases for 16-24 months and the group of infants over 6 months old had 6 cases for 7-15 months and cases for 16-24 months, 1 case for 25-30 months(p<.01).

Purpose: We investigated fecal calprotectin (FC) levels in preterm infants with and without feeding intolerance (FI), and compared the FC levels according to the type of feeding. Methods: The medical records of 67 premature infants were reviewed retrospectively. The fully enteral-fed infants were classified into two groups; the FI group (29 infants) and the control group (31 infants). Seven infants with necrotizing enterocolitis, sepsis, and perinatal asphyxia were excluded. If breast milk (BM) or preterm formula (PF) could not be tolerated by infants with FI, amino acid-based formula (AAF) was tried temporarily. Once FI improved, AAF was discontinued, and BM or PF was resumed. We investigated the FC levels according to the type of feeding. Results: Significant differences were found in gestational age, birth weight, age when full enteral feeding was achieved, and hospital stay between the FI and control group (p<0.05). The FC levels in the FI group were significantly higher than those in the control group (p<0.05). The FC levels in the AAF-fed infants with FI were significantly lower than those in the BM- or PF-fed infants (p<0.05). The growth velocities (g/d) and z scores were not significantly different between the FI and control group (p>0.05). Conclusion: The FC levels in AAF-fed infants with FI showed significantly lower than those in the BM- or PF-fed infants with FI. The mitigation of gut inflammation through the decrease of FC levels in AAF-fed infants with FI could be presumed.

The relations between micorfloral compositions and environmental factors of 32 Korean infants were sought through statistical analysis after examination of fecal bacterial and questions to their mothers about feeding experiences at three different times for each subjects, about one week after birth, before weaning (2-3 months after birth), and after weaning 95-7 months after birth). The majority of mothers fed their infants cereal foods after the age of 4 months and began weaning with fruit juice and commercial weaning foods. Defection frequencies and fecal pH of infants decreased significantly during the examination period and 37.5% of total infants in fecal samples increased significantly during the examination period, which means that the kinds of bacterial genera increase with aging of infants. Frequencies of streptococci were significantly higher in infants fed delivered by Caesarian section than infants delivered naturally. Frequencies of clostridia were significantly higher in infants fed with cereal food before 4 months of age than after 5 months. The infants fed with probiotics showed significantly higher frequencies of veillonella at about 1 week old. They also showed significantly higher frequencies of clostridia before weaning than the infant fed with no probiotics, but significantly lower frequencies of C. perfringens before weaning. The infants fed with probiotics showed significantly higher number of streptococci at the age of about 1 week and significantly higher numbers of total aerobes before weaning, but significantly lower numbers of bacteroides after weaning than their counter parts. The fecal pH was directly proportional to the number of clostridia, klebsiella, and total aerobes at about 1 week after birth, to the number of E. coli before weaning, and to the number of streptococci and clostridia after weaning. Fecal pH had a negative relationship to the total number of anaerobes in 1-week-old infants. The infants that had diarrhea during lactation showed higher frequencies of bacteroides before weaning than those that didn't.

The World Health Organization recommends that infants should be exclusively breastfed for the first 6 months of life to provide optimal nutrition in this critical period of life. After this, infants should receive nutritionally adequate and safe complementary foods while breastfeeding continues for up to 2 years of age or beyond. For nonbreastfed infants, infant formula is an available option to provide the nutrition needed. Infant formula is usually prepared from industrially modified cow's milk and processed to adjust for the nutritional needs of infants. However, cow's milk is one of the most common causes of food allergy, affecting 2%-5% of all formula-fed infants during their first year of life. One strategy to prevent cow's milk allergy in nonbreastfed infants is the use of partially hydrolyzed formula (pHF) in high-risk infants, which are infants born in families with atopic disease. However, based on an epidemiological study, approximately half of the infants who develop allergy are not part of the at-risk group. This is because the non-at-risk group is significantly larger than the at-risk group and the non-at-risk infants have approximately 15% risk of developing allergies. This study aimed to evaluate the effects of partially hydrolyzed whey formula (pHF-W) in nonbreastfed infants and determine whether pHF-W can prevent atopic disease in high-risk infants and can be used as routine starter formula regardless of the allergy risk status.
