A infancy is the period in that growth and development of man are the most fast and neutrial requirement is the most big on his life. The insufficient neutrition of this period can have bad effect uppon man's whole life health not only physically but also pscychogenically and emotionally. Therefore a proper feeding at a proper time is very important to form the good food behavior and emotional development. The rate of using the commercial weaning food in Korea has gradually increased since 1970 and expected to be more increasing in future. In this paper, I investigate the general weaning status, stneutrial component and material content of infant weaning foods marketing in Korea at present. The material for this study have been collected in the exposition of products and data from manufacturing companies and etc. The conclusion is following. 1. The proper weaning period is from $4{\sim}6$ momth to 12 momth, but recently it is inclined to prolong. 2. In weaning methods, using a spoon is superior to using a bottle in food behavior and neutrial status. 3. The commercial weaning foods have two type, the powder type and formula type, but except gober's, all products marketing in Korea are the powder type and a sort of product is very simple. Therefore it is necessary to develp the more various kind of weaning foods, especially the formula type. 4. In the neutrial component, Son-Sik (flour of grain) cannot be up to international standards and the greater parts of weaning foods have too much suger over the standards.

In this article, the writer attempted to study the followings: (1) mother's knowledge of milk feeding (including method of sterilization, formula and feeding) (2) reasons of artificial feeding (3) how much mothers are concerned about their artificial feeding infants (4) condition of growth and development of artificial feeding infants. As the object of study, 96 mothers with artificial feeding infants, who had consulted dep't of pediatrics of two Hospitals in Seoul (Korea Hospital and Med. College Woo Suk Hospital, Korea Uni.) and well baby clinic of the two Health Centers (Sung Dong and Dongdaemoon), were randomly sampled. The data were treated by the statistic method of chi-square and percentage, and come to the following conclusion. 1. Knowledge of milk feeding Sterilization: 70 percentages of mothers know about the milk sterilization (including bottle, nipple and instrument), but 55 percentages of them do not know the nipple sterilization correctly. Formula: 69 percentages of mothers follow the indicator or in accordance with doctor's directions, but 31 percentages do at their option by reasons that the baby often coughs up the milk, the baby is too small, the baby often has digestive troubles, or the baby grow fleshy heavily etc, except family economic problems. Feeding: only half of mothers know the correct feeding method, especially they do not know how to determine the heat degree of milk and how to bubble up the baby correctly. They just do feeding according to the accepted usages. 2. Reasons of artificial feeding Of the reasons of artificial feeding, 18 percentages were caused by infants and 82 percentages by mothers. Most of the reasons are mainly due to the lack of breast milk and sufficient supply of nourishments rather than mother's deficiency or mother's abnormality. 3. Mother's concern for artificial feeding infants Mothers who are sharply concerned for their artificial feeding baby's growth and development: 63%, mothers who made the baby (artificial feeding infant) routine vaccinated: 81%, mothers who ear anxious about the baby's future personality forming : 68%, mothers who care about the baby's condition of nourishment; 60%, mothers who are anxious about tile selection of baby's food; 54%. 4. The growth and development of artificial feeding infants compared with Korean average infants. The artificial feeding infants are above the Korean average infants in stature by 1.21 centimeters and in weight by 0.3 kilograms. Conclusion: It has been said that there is no better food for infant than the breast milk. However, the artificial feeding has been used for the supplement of nourishments and as substitute food for the breast milk. And this artificial feeding could give the married women the chance to act in society and more opportunity to develop themselves and to work for others at home and other fields. Considering these advantages, artificial feeding should not be exclusive, but preferably should be more improved and inquired positively. And even in artificial feeding, what is most important is that mothers should recognize the requirement and need of artificial feeding clearly and correctly, and they should be accustomed to the correct knowledge and skills of artificial feeding in order to practice it appropriately. In some degree, they should be properly trained in school education process.

The purpose of this study was to investigate lactic acid bacteria with antioxidative and probiotic activities isolated from Korean healthy infant feces and kimchi. Isolates A1, A2, S1, S2, and S3 were assigned to Lactobacillus sp. and isolates A3, A4, E1, E2, E3, and E4 were assigned to Leuconostoc sp. on the basis of their physiological properties and 16S ribosomal DNA sequence analysis. Most strains were confirmed as safe bioresources through nonhemolytic activities and non-production of harmful enzymes such as β-glucosidase, β-glucuronidase and tryptophanase. The 11 isolates showed different resistance to acid and bile acids. In addition, they exhibited antibacterial activity against foodborne bacteria, especially Bacillus cereus, Listeria monocytogenes, and Escherichia coli. Furthermore, all strains showed significantly high levels of hydrophobicity. The antioxidant effects of culture filtrates of the 11 strains included 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging capacity, 2.2'-azino-bis (2-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical cation scavenging activity, and superoxide dismutase activity. The results revealed that most of the culture filtrates have effective scavenging activity for DPPH and ABTS radicals. All strains appeared to have effective superoxide dismutase activity. In conclusion, the isolated strains A1, A3, S1, and S3 have significant probiotic activities applicable to the development of functional foods and health-related products. These strains might also contribute to preventing and controlling several diseases associated with oxidative stress, when used as probiotics.

This study was conducted in order to identify the relationship between the home literacy activities, mothers' verbal behavior, toddler-mother joint attention and the language-cognitive development of toddlers. The language-cognitive development of toddlers was assessed by means of the Mental Scale from the Korean Bayley Scale of Infant Development II (K-BSID-II). The home literacy activities were measured by means of the questionnaire used by You (2009), which was partly modified from Shapiro (1979). Lee & Kim (2004)'s categories was used to observe the mothers' verbal behaviors during shared book reading; joint attention episodes were observed by classification categories for engagement condition (Bakeman & Adamson, 1984). One of the more important conclusions of this study is our suggestion that mothers' verbal behaviors and the toddler-mother coordinated joint attention were significantly related to the language-cognitive development of toddlers as it takes place within low-income families.

The purpose of this study was to compare the different environment among the young children of large and small cities and rural areas in Korea, in order to know how these different environment have an effect on the children's intellectual and emotional development. For this subjects, 2,700 questionares with 51 items were distributed to the infants' mothers in each area to interview and answer. About 1,800 questionaires were gathered from 3 metropolitan, 6 cities and 6 rural areas in (each 2 farming, fishing and mining villages) The results of analyzing these questionaires were like following; 1. The average number of children of each family was 2.5 in large cities, 3.0 in small cities and 3.6 in the rural areas. 2. White about 75% of infants' parents of large cities graduated college education, only 6% of the rural parents did it. Most infants' parents of the rural areas have only graduated the elementary school. 3. About 90% of the rural, small and large cities family have had radios and T.V sets, and 90% of infants watched T.V program for 2 hours a day in average. 4. While about 50% of large cities' young children were not reared by their mother's milk but by milk and other foods, about 95% of rural infants by breasting mills. 5. Young children of large cities were wearing about 5 months earlier than those of the rural. 6. While 20% children of cities were taught in the kindergarten, most children of the rural areas could not be taught in the kindergarten. 7. About 45% young children of the rural areas and cities were understood and taught reading, writing letters and numbers by their parents, brothers and sisters before entering primary school. 8. While 50% young children of large cities have had pianos and were taught music in kindergarten or piano tutor's, most of the rural areas have not had pianos and could not be taught music. 9. Most children's favorite music songs were T.V signals or C.M songs in both the rural and cities. 10. While most children of cities have had lots of children's pictures or fairy tale books. most infants of the rural areas have had nothing or a few. 11. As lots of infants could not find their pleasure resorts of sport tools outside, they used to play in side streets or publicroads with their friends. 12. While most infant's parents in cities wanted to make their infants lawyer or medicine doctor, most parents in rural areas wanted to make their children teacher or technician. 13. About a half of Korean infants have had their own rooms or have lived in it together with their brother or sister. In conclusion, as children of large cities have had more various kinds of cultural circumstances than the rural areas in aspects of cultural institutions' tools and environment of their parents' education, books, toys, pleasure resorts and their own rooms, the intellectual development of the former could be considered to surpass those of the latter. In other words, the average IQ points of urban's young children are 10 point higher than those of the rural areas, which means the better circumstance would affect the infant's intellectual development. Therefore, the government must support to make good circumstances of the children in the rural areas.

The accuracy of Monte Carlo (MC) simulations in estimating the computed tomography radiation dose is highly dependent on the accuracy of CT scanner model. A system was developed to observe the 3D model intuitively and to calculate the X-ray energy spectrum and the bowtie (BT) filter model more accurately in Monte Carlo N-particle (MCNP). Labview's built-in Open Graphics Library (OpenGL) was used to display basic surfaces, and constructive solid geometry (CSG) method was used to realize Boolean operations. The energy spectrum was calculated by simulating the process of electronic shooting and the BT filter model was accurately modeled based on the calculated shape curve. Physical data from a study was used as an example to illustrate the accuracy of the constructed model. RMSE between the simulation and the measurement results were 0.97% and 0.74% for two filters of different shapes. It can be seen from the comparison results that to obtain an accurate CT scanner model, physical measurements should be taken as the standard. The energy spectrum library should be established based on Monte Carlo simulations with modifiable input files. It is necessary to use the three-segment splicing modeling method to construct the bowtie filter model.

The purpose of this study was to examine developmental trends in script-based organization strategy and relative influences of age, use of organizational strategy and category typicality of lists on children's recall. The subjects were 120 infant children, -40 four years old, 40 five years old, 40 six years old. All subjects were received 1 of 2 slot-filler lists of items differing in category representativness. Data were analysed by two-way Anova, Duncan's post-hoc test and Multiple Regression analysis. The major findings were as follows. 1. Recall and use of organizational strategy were increased with age. 2. At each age level, children showed high level of recall and organization strategy for category typical than category atypical. 3. Children's age, use of organizational strategy and category typicality of list significantly predicted children's recall. 42% of the variance of children's recall was explained by three variables. The relative influence of age to the prediction of children's recall was the strongest.
