This study explores reading fluency among elementary school students considering language level and family income(low SES). Forty eight students from 1st to 3rd grades participated in two paragraph reading tasks. Half of the children were from low income family and half of the children had low lexical knowledge. Reading fluency as in the number of correctly read syllables per minute, the total error frequency and error types were used to compare group differences. There were significant differences in the number of correctly read syllables per minute between two income groups and two language groups. There was a significant difference between low income group and non-low income group in total number of errors only when children's lexical knowledge were low. There were no group differences in error types of repetition and omission. Substitution and insertion error seemed to reflect the total error pattern. These results imply the importance of early screening and early involvement for children with low lexical knowledge from low income family. Monitoring and early intervention will support these children's reading development.

The study examined some statistics of children with disabilities, relevant research and education, and welfare policies undertaken for the last three decades. The changed perceptions regarding children with disabilities have led education and legislation to great improvement. As a result, the number of children who are registered as having disabilities has been increased. Also, children who received any benefits of education and welfare have been consistently risen. The noticeable features of the existing studies are summarized as follows : An increase in number, a variety of the contents, specification of the topics, and a close connection to the basic studies. In spite of the progression and improvement observed in the areas of education and welfare policy making, more practical approaches are needed in order to reflect various needs of children with disabilities and their families.

This study examined the effects of estimation activities on children's operation and measurement abilities. Subjects were 60 five-year-old children. This experiment used the untreated control group design with pretest and posttest. Instruments used to collect data were the Number and Operation and Measurement tests part of the Test of Mathematics Ability for Young Children (TMAYC) developed by Hong, Lee and Chung (2006). ANCOVA was employed for statistical analysis. Results of the posttest showed that children in the experimental group scored significantly higher on children's operation and measurement abilities than the control group. Results imply that an estimation program can be an effective teaching model for improving children's operation and measurement abilities.

This study examined the factors affecting the number of hours spent in child care centers by children of dual-working families. Data for this study was collected by way of a survey that involved a total of 33 child care centers. A total of 465 families took part in the study. Child factors, parental factors, household factors, and child care center factors were included in the hierarchical regression model on which this study was based. The results of this study identified eight primary factors related to the number of hours spent in child care centers by children of dual working families, which were as follows: (1) children's engagement in extracurricular activities, (2) maternal working hours, (3) parents' preference for child care center as a non-parental care provider, (4) the number of children attending the child care center in the household, (5) the presence of adults other than parents in the household, (6) accessibility to the child care center, (7) the satisfaction with child care services, and (8) the primary purpose of child care center use.

The purpose of this study is to analyze the effects of women 's perception of economic risk on the fertility gap. This study analyzed how the economic risks such as the risk of unemployment and poverty, the risk of housing insecurity, the risk of financial instability and the risk of economic downturn affects the gap between the actual number of children and the ideal number of children. For this purpose, exploratory factor analysis, reliability analysis, correlation analysis and multiple regression analysis were performed using the KGSS(Korean General Social Survey) 2014 dataset. The result of the analysis shows that women who perceived economic risk seriously had fewer children but had a higher fertility gap. This study suggested policy suggestions based on the above results.

This study introduces an automated Praat script allowing optimal formant analysis for children's vowels. Using Burg's algorithm in Praat, formants can be extracted by setting the maximum formant value and the number of formants. The optimal formant setting was determined by identifying the two conditions, F1 and F2, with minimum standard deviations. When applying the optimal formant setting determined by the script, the results of normality tests were not significant among all vowels except /e/ for the maximum formant value, and among the vowels /a/, /e/, /i/, /o/, /u/ and /ʌ/ for the number of formants. This indicates that when analyzing the formants of children's vowel sounds, the unilateral application of a parameter setting (the maximum formant value and the number of formants) to all vowels is problematic. The performance of the optimal formant setting script was evaluated along with 3 different algorithm in order to determine whether it properly extracts formants for children's vowels. To this end, Korean monophghongs of 6-year-old children were collected and the Praat scripts were applied to the data. Resultant Formant plots and statistical analysis showed that optimum_script and qtone_script, which links to the perceptual unit, performed very well in formant extraction compared to the remaining 2 scripts.

This study is focused on the amount of time spent on child care by mothers with preschool children with developmental disabilities. It is designed to find out how much time mothers spend taking care of their children and to identify related factors. The subjects of this study are 162 mothers of children with developmental disabilities residing in Seoul. The findings are as follows: First, mothers with preschool children with developmental disabilities spent 6 hours and 50 minutes per day caring for their children during weekdays and 6 hours and 10 minutes on weekend days. This is double the amount of time spent by the average mother with preschool children. Second, mothers spent much more time caring for their disabled children than they do for their children without disabilities. Third, determinants of a mother's time for caring their disabled child during weekdays were mother's employment, the number of children, and gender of the disabled child. On weekend days, determinants of mother's care time were the number of children and husband's help for childrearing.

As the result of a survey conducted by the author on the status of tile 12 educational institutions for mentally retarded children in Korea and their quartering facilities as well as on 934 children accommodated in such institutions, the following conclusion has been reached: 1) More than a half (approximately 58 percent) of the facilities for mentally retarded children are concentrated in Seoul. About eighty-three percent of these facilities are private establishments, of which 70 percent have their proprietors concurrently as their superintendents. Although these facilities were first established as many as 22 years ago, it has been only five or six years since education was actually started for mentally restarted children. 2) Out of a total of 179 employes, teachers number 99, there by constituting approximately 57.6 percent. Out of them, however, only 32 teachers or 2.8 percent have special teachers licenses. Thus, each teachers has to take care of an average of 29 children. This is excessive a number of children per teachers in view of the special nature of this education, there by indication how urgent it would be to secure more teachers lot this field. 3) Out of the mantally retarded children investigated 57.6 percent suffer from physical disorder in addition to mental retardation, 53.0 percent from mental alienation illnesses besides retardation, and 25 pent from physical, mental disorders in addition to retardation. It is therefore necessary to maintain medical and nursing facilities together with educational facilities. however, two places have no medical facilities at all, and four other places, without medical personnel, have to receive medical support from nearby hospitals or clinics. 4) The total number of children in the surveyed facilities is 934, who can be broken down into 58.7 percent boys and 41.3 percent for girls. They are classified into 12.5 percent for idiot, 37.7 percent for imbeciles, 32.7 percent for morons, and 17.3 percent for thoes children on borderline. Their average age is 13.9 years. 5) As the result of education, the illiteracy rate of mentally retarded children has decreased from 78.1 percent to 32.1 percent while the percentage of those taking the primary school course has increased for 12.2 per cent to 33.5 percent. As a result, it has been learned that education is definitely necessary for Retarded children though it may be a difficult task. 6) The children who have mentally retarded children among their brothers or sisters constitute 6.3 percent of the total number. The corresponding rate for boys is 3.5 percent while that for girls is a remarkably higher rate 10.6 percent. Through studies on the causes of their mental retardation, it has been learned that 39.6 percent of them is of the inherent type and 35.3 percent is of the environmental type. Control and improvement of health of mothers and children, early diagnosis and early treatment are believed to be very important because they could prevent or alleviant much of these conditions. 7) The storage age of teachers and employes is 35.3 years, an indication that a great proportion of them is experienced in a way or another as their major difficulty or problems in serving with these special school, 22.5 percent cited inadequate payment 24.5 gave the inadequate public understanding, and 22.5 percent pointed out the lack of understanding on the part of give parents.

The purpose of this paper is to address the theory of counting and the development of number concepts. Leslie Steffe and his colleagues developed the theory of children's counting types using the teaching experiment. As the results of their research, they published two books： "Children's counting types" (Steffe, von Glasersfeld, Richards, '||'&'||' Cobb, 1983) and "Construction of arithmetic meanings and strategies" (Steffe, Cobb, ＆ von Glasersfeld, 1988). They classified children's counting types into five categories： Perceptual Counting Stage, Figural Counting Stages, Initial Number Sequence Stage, Tacitly Nested Number Sequence Stage, and Explicitly Nested Number Sequence Stage. The meaning of this theory is added in the last part of this paper. this paper.

The purpose of this study is to fined out the characteristics of using & change of the residential space according to the children age and family life cycle. The results of this study are as follows: The first, as children grow up, children's activity space changed from living room to the private room, and housing condition was related to the frequency of each activity. The second, as children grow up, family's sleeping pattern changed, and this change effected the number of private rooms for sleeping and the use of the extra room. The third, changes of the using of dwelling space come out several pattern, increasing bedroom number through reconstruction, exchange of An-band and children room, parents' sleeping space move to living room, and change the function of rooms. The change pattern of the correspondence to the housing needs differed from each family life cycle stage.
