  • In this study, we looked into the method to establish fire growth rate by buildings use for growing fire at the beginning of a fire considering the characteristics of the combustibles in a performance-based design. Actual conditions survey and literature review were carried out for the fire load and exposed surface area of combustibles to establish design fire by domestic building use. As a results, a simplified prediction equation of fire growth rate which depends on fire load and weight of combustibles could be derived by calculating the relation between the fire load and the fire growth rate of an initial fire through investigation of combustibles by domestic building use.Also, as a result of analyzing the placement of combustibles and location of the ignition source, it was found that the influence of the materials of the combustibles and the materials of the combustibles adjacent to the ignition source is big. Though 4 different experiments were carried out for the evaluation, the result of comparing the findings with those of FGR model showed that the fire growth rate was similarly derived.

  • This study was carried out to investigate the feeding practices, growth status and correlation with maternal perceptions of breast feeding and lactation with infuts' feeding methods in the Pocheon area. The subjects were 103 infants ranging from 3 to 21 postpartum months and their mothers. The results obtained were as follows : In this survey, 36.9% of the infants were breast-feeding, while 53.4% of them were bottle-feeding, and 9.7% of them were mixed-feeding. The reason for bottle-feeding was due mainly to the lack of breast-milk secretion. Z-scores of weight-f3r-age and height-for-age were similar to Korean standards, but malnutrition and overnutrition were also noticed by kaup index and WLI. The average maternal perceptions of breast-feeding and lactation was 3.7 out of 10 possible points, the breast-feeding group scored 4.7, and formula-feeding and mixed-feeding group scored 3.0. That of BF group was higher than FF+MF groups and was positively correlated with growth status. Therefore to ensure proper growth of infants and to promote breast-feeding, efforts should be given to community nutritional services including nutrition education for the importance of colostrum and breast-milk, practical breast-feeding methods, and nutritional management during pregnancy. Also nutrition education for mothers will be continued to 1-3 postpartum months to promote successful breast-feeding.

  • Purpose - This study aims to analyze the relationship between trends in innovative EU industries and market distribution in smaller emerging markets under an open economy. Research design, data, and methodology - Although innovation was well-distributed, due to socio-economic factors following European integration, CEE had not achieved sustainable economic growth. However, this paper analyzes the differences among changes in CEE innovation for smaller emerging markets dominated since 2000. Market distribution has facilitated new markets for innovative industries, according to EU surveys and economic indicators. Results - The dominance of the local industrial market distribution has deterred innovation investment the survey shows that innovation investment has been shrinking, despite the EU's open innovation policy for CEE employment and R&D. For the CEE case, there were expectation gaps and uncertainty about whether to use the new distribution dominance or TNCs' innovation in smaller emerging countries without local industrial innovation. Conclusions - Innovation generates market growth and distribution power however, small growth requires stimulation, and creativity and innovative edge need further focus in local public and corporate strategy.

  • Growth mixture modeling was used to identify types of changes in overt aggression from Grades 4 to 7 among a sample from the Korean Youth Panel Survey. Three discrete patterns were found to adequately explain changes of overt aggression in both boys and girls : Persistent intermediate aggression; Increasing aggression; and Decreasing aggression. Most boys (93%) fell into the Persistent intermediate aggression group and 49% of girls were found to fall into the Increasing aggression group. This suggests that prevention programs should recognize that girls are at risk of increasing aggression in their early adolescence. Multinomial logistic regression analysis shows that self-control, child abuse, peer support, and involvement with deviant peers at Grades 4 were all strongly associated with trajectory class membership. These associations did not differ by gender. These findings suggest that prevention programs should focus on the multiple risk factors of both boys and girls.
