Injury is a leading cause of death in the children and adolescent populations. In particular, more than 80％ of unintentional injury was related to risk-taking behaviors involved in diverse accidents around school and home. Therefore, educational approaches should be provided for children and adolescent populations, and schools are the essential and appropriate sites to conduct safety education. This study was conducted to identify injury prevalence and safety education at schools among middle and high school students in Korea. About 1,034 middle and high students in 28 schools participated in a self-administered survey. The target schools were selected from the stratified random sampling method throughout schools of seven metropolitan cities in Korea. The questionnaires were delivered to the vice-principals by ground mailing service and the vice-principals administered survey data collection. The questionnaire asked about safety education provided in schools, injury experience in the last year, needs for injury prevention class in school, and demographics. All survey responses were entered into SPSS worksheet. Multivariate analysis of variance (MANOVA) and descriptive discriminant analysis (DDA) were used in statistical analysis with SPSS software 11.1. Multivariate analysis of variance was conducted as a preliminary analysis of DDA. According to the result of multivariate analysis of variance, gender (man), grade (poor), living with both parents, and displaying injury prevention messages on school news board were significantly different between the injured student group and the uninjured student group (p＝ .00). These four factors also had significant effects on students' injury experience in DDA, although correlation of the four factors with injury experience was weak overall based on their canonical function coefficients. All structure coefficients of the four factors were greater than .30, which means the four factors have discriminant effects on injury prevalence. The sizes of the discriminant effects, in order, were largly from gender, grade, living with both parents, and safety message display on school news boards.

In modern society, we are living indoor at 80 - 90 % or more of the day, therefore most people are exposed to unconscious indoor air pollutants by various causes. When mother and infant, whose level of immunity are weak, are exposed to polluted indoor air, respiratory diseases and atopy can occur by the growth of bacteria. Therefore, appropriate indoor air quality management is important especially at nursery, elementary school and postpartum clinic etc. In this study, we compared the characteristics of the indoor air qualities of primary school facilities and infant facilities. In this study, seasonal effects were investigated. Also the effects of individual activity area were studied for indoor air quality. During summer season(May-August), the air qualities of each 16 elementary school and nursery school were investigated. During winter season(October-december), the air qualities of each 10 elementary school and nursery school were investigated. As a result, during winter season in 10 of 16 nursery school, $CO_2$ concentration exceeded regulation level of 1000 ppm. This resulted from the operation of heating system and poor ventilation. Also the air quality of all parameters during winter season were worse than during summer, maybe due to poor ventilation. Except HCHO, the concentrations of other parameters were higher in nursery school. This seems to result from relatively low individual activity area of nursery school than elementary school. From this research, more strong regulation for ventilation and installation of air purifier should be implemented.

Background: Researchers have previously commenced examining the degree of concordance between parent proxy and child self-reports on health-related quality of life (HRQOL) of many disease and impairment populations. Objects: To explore the differences between parent proxy and child self-reports on the HRQOL using Korean version of KIDSCREEN-10 questionnaires for applying to elementary school children and their parents who participated for a school-based wellness program. Methods: The focus groups were recruited for a school-based wellness program by implementing the following wellness services: 1) referring to a screening session for detecting potential posture-related musculoskeletal problems and 2) recommending home exercise programs. Before a primary field testing for the program, two focus groups were formed with a group of 9 parents and their 9 elementary school children aged 8-10 years of age. The parent proxy and child self-report versions of KIDSCREEN-10 questionnaires were administered to both groups after completion of the wellness program. Item level Rasch rating scale analysis was applied to compute logit scales of KIDSCREEN-10 questionnaire. Intraclass correlation coefficients (ICCs) and scatterplot of item difficulty between two reports were analyzed. Results: For fit statistics of parent proxy report, all items except 4 items (i.e., psychological well-being, mood/emotions, self-perception, parent relation) were found to be acceptable. For fit statistics of child self-report, all items except 3 items (i.e., psychological well-being, autonomy and home life) were acceptable. The relationship between two reports using ICCs were ranging from weak to very strong at p = 0.05 (i.e, ICCs = 0.011 to 0.905). Scatterplot analysis between two reports showed a major disparity on self-perception item at 95% confidence intervals. Conclusion: Both item level analyses and ICC comparisons provided a disparity between parent proxy and child self-reports of the HRQOL on self-perception item after competing a school-based wellness program. Therapist should consider the item as part of the HRQOL assessment.

Demand of natural interior finishing material has been widely sprayed in nowadays because many weak people as children, pregnant women, and elder people are being struggled with sick house syndrome due to volatile organic compounds such as formaldehyde, toluene, benzene, etc. Our research group developed a no-added formaldehyde adhesive for wood-based panels from mainly rice powder and some additives in the previous study for abating sick house syndrome. Since the rice powder adhesive provides a good source of nutrients with microorganisms, it was suspected a susceptibility of the rice powder adhesive to fungal and sapstain attack. We evaluated anti-sapstain activity of the rice powder adhesives modified by adding wood preservatives. We modified the rice powder adhesive by adding three different types of anti-sapstain preservatives at three different concentrations to assess their anti-sapstin activity. The bonding strengths of the modified rice powder adhesives were still outstanding performance on all samples. Moreover, the plywood manufactured with the modified rice powder adhesive satisfied outdoor use requirement for ordinary plywood (KS F3101, Korean Standard). The results obtained showed that at least 3% of preservative should be added to the rice powder adhesive to obtain effective anti-sapstain activity.

This study purposed to survey grandparents' difficulties in parenting their grand children at grandparent-grandchild households in South Jeolla rural areas. This study was conducted through in-depth interviews from January to October, 2008. The subjects were eight grandparents living with their grandchildren in Boseong-gun, Gangjin-gun, Yeonggwang-gun, Hampyeong-gun, Haenam-gun and Damyang-gun in South Jeolla province. The results are as follows: the grandparents' difficulties in parenting grandchildren are divided into four categories of variable factors: 'Difficulties related to grandparents themselves'; 'Difficulties related to their grandchildren'; 'Difficulties related to early childhood education institution: and 'Difficulties related to their grandchildren's peer group or surrounding people'. The main difficulties in these categories are 'poor, aging and weak conditions of grandparents: 'conflicts in their parenting attitude to have compassion on grandchildren: 'grandparents' not enough educational support to grandchildren due to their ignorance about today's education system: and 'anxiety about the possibility for their grandchildren to be abandoned once again.' These results can be used as a piece of basic information for desirable supports to grandparent-grandchild households.

In the Grid Database, some replicas will have more requests from the clients than others. A fast consistency algorithm has been presented to satisfy the high demand nodes in a shorter period of time. But it has poor performance in multiple regions of high demand for forming the island of locally consistent replicas. Then, a leader election method is proposed, whereas it needs much additional cost for periodic leader election, information storage, and message passing, Also, false leader can be created. In this paper, we propose a tree-based algorithm for replica update propagation. Leader replicas with high demand are considered as the roots of trees which are interconnected. All the other replicas are sorted and considered as nodes of the trees. Once an update occurs at any replica, it need be transmitted to the leader replicas first. Every node that receives the update propagates it to its children in the tree. The update propagation is optimized by cost reduction for fixed propagation schedule. And it is also flexible for the dynamic model in which the demand conditions change with time.

Together with the concern about the indoor air quality as sick house syndrome, the Ministry of Environment announced "Indoor Air Quality Control Law for the Multi Purpose Facility," which made the interests to be focused in the urgent understanding of current condition and preparation of measures about the indoor air pollution. The law was revised to obligatorily notify the amount of Formaldehyde and Volatile Organic Compounds in the case of newly constructed apartments with more than 100 houses. School also have its own indoor air quality guideline. Indoor air quality in school is very important because, children who very weak to indoor pollutants reside long time in there. The purpose of this paper is to to survey indoor air quality in school by field measurement. Field measurements were performed in 11 schools which were selected from 3 major cities(Incheon, Dae-jeon, chuncheon) in korea, Totally concentration of indoor pollutants were determined in 32 classroom. Target air pollutants were TVOC, formaldehyde, dust, CO, CO2. For the result of this investigation, Indoor air quality in classroom was very poor and it was found that some pollutants(TVOC, float bacteria) exceed the guideline.
