Objectives: The purpose of this study is to estimate genetic and environmental factors which can effect growth, and predict final height using this factors. Methods: Correlation analysis and regression analysis were conducted between measurements of height and Genetic & environmental factors through survey from 1352 child & adolescent patients. Results: Factors which have correlation with height percentile are MPH(Mid-Parental Height), NBW(Neonatal body weight), anorexia, dyspepsia, atopic dermatitis, frequency of breakfast and quality of sleeping time. MPH has moderate relation, NBW and anorexia have fair relation, and other factors have linear but poor relation. Regression equation from factors which have correlation and height percentile has 26.9% of predictive power. Regression equation considering only genetic factor has 20.4%. MPH has the most effect on height percentile. Anorexia has more effect than NBW. Other factors also have small and similar effect. Conclusions: Height of parents has the most effect on growth, anorexia, dyspepsia, atopic dermatitis, frequency of breakfast and quality of sleeping time also has effect.

The purpose of the present study was to examine the relation of total antioxidant status (TAS) to metabolic risk factors in Korean adults. Anthropometric measures, blood pressure, serum lipids and fasting glucose were determined in 406 men and women. TAS was measured by using commercially available Randox kit. Serum TAS was significantly positively correlated with body weight (p=0.004), body mass index (BMI) (p=0.033), waist circumference (p=0.017), total cholesterol (p=0.038) and triglyceride (TG) (p<0.001). The mean TAS of hypertriglyceridemic subjects (TG ${\geq}$150 mg/dl) was significantly higher than that of subjects whose TG was lower than 150 mg/dl (p=0.001). When central obesity, TG, high density lipoprotein cholesterol, fasting glucose and blood pressure were considered as metabolic risk factors, TAS was shown to be elevated with increased number of metabolic risk factors (p=0.004). The positive association between TAS and a number of metabolic risk factors suggests that increased TAS may not always indicate one's healthier condition. In order to help understand TAS as a marker of total antioxidant capacity in humans with various metabolic conditions, it is needed to clarify the factors affecting TAS in relation to changes in metabolic risk factors.

The purpose of this study is to consider the relation between the deciding factors of local identity and local image improvement. To achieve this purpose, the deciding factors of local identity have been set as the following four: historical identity, cultural identity, (nature) scenery identity, and industrial identity. The writer has established a model to represent the relation between these factors and the local image improvement, namely 'Visitor Satisfaction' and 'Revisit Intentions', and framed a hypothesis for empirical verification. The study results are as follows: First, the deciding factors of local identity which this study addressed are empirically proven to have a significant effect on the visitor satisfaction and the intention to revisit in which is it likely that the greater the impact of the deciding factors, the higher the visitor satisfaction and revisit intentions would be. Second, the deciding factors of local identity, it appears that the 'historical identity' factor had the largest impact on the visitor satisfaction, and the 'cultural identity' factor had the largest impact on the revisit intentions. Therefore, of the four deciding factors, the 'historical identity' should be considered the highest priority to increase the visitor satisfaction, and the 'cultural identity' should be considered the highest priority to increase the revisit intentions. Third, based on the verification of the relation between the visitor satisfaction and revisit intentions, it can be presumed that the greater the visitor satisfaction, the higher the revisit intentions would be.

The present study purposed to examine adolescents' peer relation quality, and school life maladjustment according to the characteristic of their mobile phone use and their mobile phone addiction. The subjects of this study were 490 middle/high school students in Namyangju City. A survey was conducted using a self reporting questionnaire, and collected data were analyzed with SPSS 12.0. The results are as follows. First, mobile phone use was different according to gender, school year and the degree of mobile phone addiction. Second, the addiction group was 12.9% of the subjects, the dependent group was 52.7%, and the non addiction group and 34.5%. Third, in the addiction group, the negative factors of peer relation quality were significantly higher than the positive factors of peer relation quality. Fourth, in the addiction group, all the factors of school life maladjustment were significantly high. Fifth, school life maladjustment was higher when the degree of mobile phone addiction was high and when the negative factors of peer relation quality were high. This suggests the necessity for education on the right use of the mobile phone and mobile phone addiction treatment program; in order to improve adolescents' peer relation quality and ease their school life maladjustment. The results of this study are expected to be useful in developing effective interventions for adolescents' healthy growth.

SNS is one of the fastest service entering in mature stage. But now there are not any empirical analysis the effect of SNS from user point of view. In this paper, we investigate the effect of self presentation on SNS to interpersonal relation and intention to use. we set online presentation self-efficacy and involvement as two antecedent factors. And we suggest that the purposes of using SNS be Image improvement and knowledge contribution. The change of interpersonal relation in offline is set a result of using SNS and a mediating variable between online self-presentation and intention to use. In the results, firstly, we confirmed that the online presentation self-efficacy and involvement are predisposing factors for online self-presentation on SNS in the positive direction. Secondly, the using SNS has significantly positive effect on the change of interpersonal relation. Especially, the improvement of interpersonal relation is originated from image improvement and knowledge contribution. Thirdly, the improvement of interpersonal relation have also significantly more higher effect on the intention of use.
