The purpose of this study was to compare the social competence of children in onechild and twoor morechild families and to investigate such relate variables as sex and presence of grandparents. The sample of this study was 120 mothers selected from the children´s kindergartens in Seoul. Iowa Social Competency Scales were used to measure the children´s social competence. The data were analyzed with ttext and twoway ANOVA. There were no significant differences in any dimension of children´s social competence between children in onechild and towor morechild families. In onechild families, there we re no significant effects but some significant interactions according to sex and presence of grandparents in the child‘s social competence. In twoor morechild families, there were some significant differences according to sex and presence of grandparents in the social competence of children.

The purpose of the present study is to determine the levels of maximal oxygen uptake and anaerobic threshold of boxing players(n=23), ken-do players(n=18), Judo players(n=12), T.D.K players(n=18). Treadmill test was used to measure maximal state and anaerobic threshold of metabolic variables. Treadmill exercises protocol was 2-min incremental test from an initial work load of 0MPH(grade : 0%) to all-out by step of 1.0MPH(grade : 2%). The results of measurement was as follows : 1. Absolute(1/min) and relative(ml/kg/min) maximal oxygen uptake was highest(5.08l/min, 65.01 ml/kg/min) in Judo layers, followed in order by the T.D.K players (4.37l/min, 64.74 ml/kg/min), Boxing players(4.18) l/min, 63.19 ml/kg/min) and ken-do players(3.81l/min, 58.65 ml/kg/min). It is not significant difference in the relative maximal oxygen uptake, but is significant difference between group in the absolute maximal oxygen uptake(p<0.001) 2. AT-VO₂(l/min) and AT-VO₂(ml/kg/min) in the anaerobic threshold was highest (3.71 l/min, 47.28 ml/kg/min) in Judo players, followed in order by the T.K.D players(3.29 l/min, 48.75 ml/kg/min), boxing players(2.90 l/min, 43.91 ml/kg/min) and ken-do players(2.82 l/min, 43.52 ml/kg/min). It is not significant difference in the AT-V02(ml/kg/min), but is significant difference between group in the AT-V02(l/min). (p<0.001) 3. %HRmax and %V 02max in the anaerobic threshold was not significant difference between group.
