Purpose: The current descriptive study examined the health and healthcare status of preschoolers in poverty group compared to those of comparison group. Method: Data were collected from 51 mothers in federal poverty group and 49 in low-income group and 200 mothers in normal income comparison group in one city. The instruments used for this study were Korean CBCL and health related questionnaire. Results: Public assistance group showed more low-birth-weight infants, developmental delay, and hospital admission experiences. Their compliance for vaccination and congenital metabolic disorder test were lower than those of comparison group. Preschoolers' behavior problems were not significantly different depending upon the income of the group. Conclusion: Preschoolers' health and healthcare status are affected by the socioeconomic characteristics of the family. It indicated an need for anticipatory guidance and early intervention that might help to prevent or ameliorate potential health problems in poverty.

The environment is very important to the human being, most of all, infant is sensitive to the environment because infant is on the way to the brought-up. The Furniture in living space is a medium to connect a house and dweller, and is intimately relate to the living environment. Therefore we have to consider the infant various behavior for the plan of infant furniture. But studies on the infant seems not to have concern of infant environment as a living. Specialty, the demands of the adults for space is up to express in living space, but that of infant is latent. Also the demands of infant is difficult for the adults to be understood. So the studies on the infant furniture through the Infant playing behavior have to be achieved for the proper infant cultural environment.

Currently, there is no library only for children in Korea, but as people realized that reading education was important, public libraries have started making space for children. However, most of spaces in public library were designed regardless of physical development and behavior. Therefore it was even worse for children to use library. Planning must be concerned about indoor surroundings that satisfy children's psychological desire and characteristic. Consequently, this study is going to have a thorough grasp of the problems of children library, and present organized information which fits their reading environment and human technology.

501 preschool children from 4 to 6 years were examined for their salivary reductase activity and caries experience by Resazurin Disc Test and dental examination respectively. We asked the parents about their children's oral hygiene habits, between-meal eating habits, and physical exercise habits by the questionnaire. Toothbrushing frequency had negative relation to salivary reductase activity and caries experience. Caries experience was low when parents did toothbrushing for children, when teeth were brushed at bedtime, and when fluoride toothpastes were used. Salivary reductase activity and caries experience were high in bread & cookies group, chocolates & candies group, milk & soft drink group, and fruits & vegetables group in order. Caries experience was high in case of irregular between-meal eating. Sweet food eating frequency had positive relation to caries experience. Caries activity was low in case of eating homemade non-sweet between-meals. Salivary reductase activity and caries experience were low when gum-chewing frequency was high. Salivary reductase activity and caries experience were high when the amount of physical exercise was low.

The purpose of this study was to do an epidemiological survey of the salivary reductase activity and dental caries prevalence of the large group of preschool children and analyze the validity of the salivary reductase activity test as a caries activity test. One thousand and forty-four preschool children were examined for caries experience and salivary reductase activity by dental survey and the Resazurin Disc Test. 39.8% of children showed low salivary reductase activity, 39.4% showed middle, and 20.8% showed high. Salivary reductase activity increased as age increased. All indexes of caries experience were high when salivary reductase activity was high. There was positive relation between salivary reductase activity and caries experience. The salivary reductase activity of children with no caries experience was lower than that of children with caries experience. The salivary reductase activity of children with low caries experience was lower than that of children with high caries experience. It seemed that the salivary reductase activity test had basic validity as a caries activity test. However, the test's ability to select the small risk group of high caries susceptibility should be enhanced.

This study aims to identify the beneficial effects of forest experience on emotional changes in young children who are exposed to smartphones in daily life. This research was conducted on 41 children aged five and six years at a kindergarten in Chungcheongnamdo province. The children participated in a five-month forest experience program, conducted twice a week. Before beginning the study, its purpose and procedure were explained to the children's parents and kindergarten teachers, after which written content was collected. Before and after the five-month experience, questionnaires about smartphone use and emotional conditions were administered through the parents. The participants were divided into two groups, namely average-use and high-use groups, depending on the smartphone addiction proneness score. It was found that negative psychological subscales such as anxiety, impulse, and depression decreased following the five-month forest experience in both groups. Positive psychological attitudes such as sociability and creativity increased significantly after the forest experience. The high-use group showed a wider range of positive changes compared to the average-use group. Accordingly, forest experiences can be used as an effective solution for smartphone addiction problems among young children.

Objectives: This study was conducted to reveal the biological basis of dental plaque and preschool children's dental health status through repetitive and continuous toothbrushing instruction to preschool children, using quantitative criteria, and to emphasize the importance of the role of an oral health manager for the prevention of dental caries. Methods: After IRB approval, toothbrushing instruction and oral microbial specimen collection were conducted with children of preschool age at the Daycare Center attached to D. University, Busan. Specimens from 27 children were characterized by analysis with real-time multi-chain enzymatic polymerization reaction technique at an agency specializing in genetic analysis. Results: In a survey of the children's dental health behaviors, 48.1% responded that the toothbrushing time is 91 to 150 seconds; 66.7% responded that the frequency of toothbrushing is more than three times per day; 81.5% stated that they performed tongue brushing; and 81.5% brushed their teeth. Regarding levels of dental cariogenic bacteria, after children received continuous toothbrushing instruction, there were reductions in both Streptococcus mutans and Streptococcus sobrinus. Regarding toothbrushing time, the time increased in relation to the presence of instruction. Regarding Quigley Hein Index, the index decreased in the early and middle periods upon addition of instruction, then increased in the middle and later periods. Conclusions: Through persistent and repetitive toothbrushing instruction, healthy behavior can be positively established in children of preschool age; it is necessary to prepare institutional measures so opportunities for dental health education can be consistently provided and maintained. In the future, it will be necessary to conduct a follow-up study to verify the factors affecting toothbrushing time and volume of oral pathogens.

Objective : The purpose of the study is to examine the length of institutionalization and sensory modulation for preschooler without disabilities, and to investigate the relationship between the length of institutionalization and behavioral problem. Method : Mothers of preschoolers without disabilities between ages of 3 and 7 who attend D kindergarten was participated. Nursery school teacher of institutionalized children without disabilities between ages of 3 and 7 who attend child-welfare facilities was participated. We used Short Sensory Profile(SSP) and Children Behavior Check list. The results were analyzed with SPSS 11.0. Results : There was no significant difference between longer length of institutionalization and shorter length of institutionalization in sensory modulation and behavioral problem. Regarding the sensory modulation and behavior problem according to child-welfare facilities, means showed the statistically significant difference. Regarding sensory modulation of test items, movement sensitivity and low energy/weak showed the statistically significant difference in home-reared children than institutionalized children. Conclusions : The results of the study showed high correlation environmental effect in institutionalized children. Further research is needed to improve environmental for institutionalized children.
