Nowadays, the degree of women participation in society is increasing due to modern society's industrialization and urbanization. Already enrollment of kingdergarten is nearly 30 percent higher already since 2005. Moreover, the figure is swing upward this 2014. therefore, including nursery and day care center have to consider to the highest rate. On the other hand, toddlers in our country spend most of their time in the kindergarten center. So people have to take look at possibility of accidents and we are aware about it. As a result, It was announced that the standard of education for the prevention of accident should be implemented in the toddler's facilities. Despite of accompanying education, The percentage of infant's accident is consistently growing every year. in accordance with that, we need to study about architectural planning considering the rage of the activities for child. Externally, infant safety training is being implemented on current regulation. but, the standard of toddler safety is not internally executed in that facilities. In this study, I analyzed the types of toddler's accident on statistics. I visited different web sites about kindergarten and I also made a research through an interview with a preschool teacher.

The qualify of preschool education is related to the qualify of the physical environment, This research is aiming to develop and validate the set of scales for the measurement of physical quality of the interior spaces in child care facilities. The research has been in three major phases: (1)the development of indicative sub-scales for the description, measurement and evaluation of the physical designed quality of early childhood environments (2)two rounds of iterative phases of reliability and validity testing of the scales through expert panels and observational field-testing and (3)implications for future research to be done. 13 sub-scales were developed, which are based on Moore's 15 design principal for child care environments. And each sub-scale includes several evaluation items based upon developmental theory, existing empirical literature, and Korean, Australian and American child care standards. This set of scales will (1)aid research on the effects of environmental variables on quality of child care facilities for infants, toddlers, and preschoolers; (2)permit evaluation of such environments to identify areas of needed improvement; and (3)provide information for policy makers, parents, administrators, and designers/architects.

Residents of apartment complex make various attempts for their community. However, a community space in current apartment complex is planned uniformly without consideration of residents' diversity and the physical aid environment for aged people, children and the handicapped is in limited supply. Community spaces in apartment complexes satisfy various residents but need further study about this. The purpose of this study intends to evaluate the applicability of Universal design of community in apartment complex. Research was done examining 12 different apartment complexes in Seoul, which were all built after the year 2002. Researched community spaces were the senior citizen's center an indoor exercise area and a preschool which were evaluated and measured by passage areas, ramps, stairways and entrances. As a result, the study found that application of Universal design of community spaces in apartment complexes were evaluated relatively low. The environment of community space in apartment complex is not considered the blind, deaf, disabled, children and aged people because the application of these categories doesn't be enforced a law. Hence, Universal design regulations and design guidelines were established to satisfy residents of apartment complex.

This study was carried out to investigate foodservice management practices of 100 child care centers nationwide, and to provide background information for developing foodservice management policies at child care centers. Approximately 20% of the child care centers had a separate dining room; most of the centers were vulnerable to sanitation or safety problems. The percentage of the centers that planned menus was about 60% and 10% established standardized recipes. Fourteen percent of the centers kept records for distribution and menu evaluation and 33% kept sanitation management records. Since only 7% of the centers employed a dietitian, foodservice in most centers were not managed by professionals. The results of menu assessment revealed that 56.5% of the national/public child care centers received 19 points or higher out of 21 points, whereas 5.6% of the private child care centers received the same scores. Proper usage and storage of raw food, sanitary management of equipment and facilities, waste management/leftover food treatment, and basic facility of cooking zones were performed well by many centers. The overall scores of foodservice performance were only 31.2 out of 60 points, representing relatively poor safety management, food procurement management, and facilities and equipment management. These results indicate that the foodservice management of the child care centers are in a relatively poor state. Since nutrition management of the most centers was performed by non-professionals, it may not be possible to provide proper nutrition for health and normal growth of preschool children and to perform efficient nutrition education programs. The following suggestions are strongly recommended in order to improve foodservice performance at child care centers. First, foodservice administration should be performed by a dietitian, and second, efforts should be focused on strengthening nutrition and sanitation management.

Background: Children who use playground facilities are exposed to potential risks due to the high concentration of heavy metals contained in the finishing materials of facilities in children's playgrounds. Objectives: The purpose of this study was to investigate the concentration of heavy metals in the finishing materials of outdoor children's playgrounds where harmful heavy metals exist in Gwangju and to conduct human risk assessment for children and adults by age to find the risks and limitations. Methods: The bottom and top layers of double-painted paint were peeled off and collected together from the finishing materials of children's play facilities such as slides, swings, and seesaws in 147 children's parks in Gwangju. Heavy metals were analyzed using ICP-OES, etc., and human risk assessment was performed using the concentrations of heavy metals. Results: Based on 1.0E-04, which requires legal regulation, CTE was found to pose a carcinogenic risk for preschool children and no carcinogenic risk for the rest of the age groups. However, RME showed that both men and women of all ages had a carcinogenic risk. For reference, when the carcinogenic risk was based on 1.0E-06, CTE was found to pose a carcinogenic risk from infants to elementary school students, and RME was found to have a carcinogenic risk in all age groups. It was judged that there is a non-carcinogenic risk if the non-carcinogenic risk exceeds 1 based on the hazard index (HI) 1. In CTE, there was no non-carcinogenic risk, and RME for preschooler males (1.49E+00) and females (1.56E+00) were found to have non-carcinogenic risk. Conclusions: This study was meaningful in that it examines the differences in the current management of heavy metals concentration standards and potential carcinogenic and non-carcinogenic risks to the human body and discusses the relationship between heavy metals and human health effects.

Objectives: Although the risk assessments for nitrogen dioxide ($NO_2$) and ozone ($O_3$) have been extensively studied, most of the existing risk assessments were limited mainly to indoor environments such as workplaces, schools, and multi-use facilities. Therefore, integrated risk assessment is needed to consider exposure in all microenvironments, including outdoors. The purpose of this study was to assess the differences in risk among sub-population groups according to time-activity patterns and reported concentrations, as well as the lifetime risk of Koreans. Methods: In this study, we estimated time-weighted average exposure concentrations of $NO_2$ and $O_3$ for preschool children, students, housewives, workers, and seniors using residential time and indoor concentrations (house, school or workplace, other), outdoors, and transport by meta-analysis method. The risk for $NO_2$ and $O_3$ were assessed by hazard quotient using reference concentrations 30 and 60 ppb, respectively. The risk assessments were conducted through 1,000,000 Monte-Carlo simulations for probabilistic analysis. Results: Preschool children, students, housewives, workers, and seniors spent 91.9, 86.0, 79.8, 82.2, and 77.3% of their day in a house, school, or workplace, respectively. The risk assessment for the lifetime of a housewife and a worker showed that 33.8 and 28.4% of hazard quotients of $NO_2$ exceed 1, respectively, and more than 99% of hazard quotient of $O_3$ were less than 1. Conclusions: The risk of $NO_2$ and $O_3$ by sub-population group and for the lifetime of housewives and workers were assessed. The risk for $NO_2$ was higher than for $O_3$ and showed a different risk by sub-population group. Both $NO_2$ and $O_3$ showed a higher risk for housewives than for workers. This study can be used as a basis for lifetime exposure and risk assessment for $NO_2$ and $O_3$.

Objectives : The oral care during early childhood plays an important role to maintain sound oral health during adulthood. As the number of children's using child care facilities is on the rise recently, the children's oral health awareness and behavior of the educators at nurseries and kindergartens are to be examined. Methods : A self-recording survey was conducted on 194 educators at the nurseries and kindergartens in Chungnam region. Results : The most frequently given snack was milk, 91.8 percent of the facilities had children brush their teeth, 63.4 percent made them apply fluoride and 56.2 percent kept children's toothbrushes in an ultraviolet rays sterilizer. There was a meaningful difference in the awareness of the necessity to educate children about oral health according to the offer of the opportunity to apply fluoride (p<0.05). A meaningful difference was found in the recognition of the necessity to educate children according to their grade (p<0.05) and to train teachers themselves (p<0.05). The most desirable persons in charge of oral health education were dentists in health centers (46.9%) in order. The more experience in teaching they have had (p<0.05), when they're married (50.5%) (p<0.05) and when they're not homeroom teachers (52.6 percent), the more regular checkups they have had (p<0.05). As for the importance of oral health and the results of regular checkups, those who had answered 'very important'(42.4%) showed higher rate of regular checkup (p<0.05) than those who had answered 'important'(23.9%). When teachers have the experience to get trained about oral care (96.3%), the practice frequency of brushing teeth was proved to become higher (p<0.05). Conclusions : The educators for children should recognize the importance of oral health education, educate children to practice oral health care, and the environment and systematic foundation should be established which the educators manage effectively.

Objective : The purpose of this study were to examine internal reliability and internal validity for Short Sensory Profile(SSP) and to suggest the useful criteria for sensory processing abilities in Korean culture. Methods : The Short Sensory Profile(SSP) was completed by mothers of 304 children typically developing between 3 to 10 years of age in those preschool, kindergarten and elementary school located Seoul and Gyeonggi-do. The total agency for this study was 14 facilities and the period of study was from July, 2002 to June, 2003. Kim Mi Sun(2001) translated and modified the Short Sensory Profile that Macintoshi developed and the tool for the study was used. The data were analyzed with reliability test and Pearson's correlation. Results : 1. Internal reliability of the total tests and sections was estimated by calculating Cronbach's Alphas. Reliability value of the total tests was .889. 2. For internal validity the correlations range from .131 to .575 in magnitude, suggesting that the sections of the Short Sensory Profile tap relatively unique constructs and support the factor structure developed. 3. The total score of the Short Sensory Profile(SSP) range from 118 to 190, mean and SD was 163.12, 14.87. 4. Of 403 children represented by the survey, 32 children(10.5%) met criteria for sensory processing disorders based upon parental perceptions. 5. Cut scores were determined by computing the raw score cut scores for -1 SD and -2 SD. The normal group of sensory processing abilities had score which range from 190 to 149, the probable problem group had score which range from 148 to 134, and the definite problem group had score which range from 133 to 138. Conclusion : Findings from the above study suggest that Short Sensory Profile be the screening tool for sensory processing disorders within Korean culture. Further research is needed to compare with children with the various sensory processing disabilities(PDD, LD, CP ect,).
