This paper shows that when children's ability is heterogeneous, a parent's choices about educational expenditures and fertility follow a pooling equilibrium or a separating equilibrium. Which of the two equilibria will prevail depends on the probability of getting a high-ability child as well as productivity differentials in producing children's adult human capital. Adopting the model of Acemoglu's (1999), this paper presents that the outcome of the pooling choice in the pooling regime and the outcome of the separating choice in the separating regime make the growth rate of human capital higher than otherwise. In addition, as the probability of a high-ability child increases, the growth rate of human capital in the separating equilibrium exceeds that in the pooling equilibrium.

Purpose: The purpose of this study was to evaluate the The Influence of contract-relax exercise of PNF on Equilibrium Ability. Methods: The subjects were consisted of thirty patients (14 females and 16 males). They were from 20 to 42 years old and the mean age was 25.03. All subjects were randomly assigned to two groups: contract-relax exercise of proprioceptive neuromuscular facilitation(PNF) group (n=15), control group (n=15). Contract-relax exercise group received contract-relax exercise for about 10 minutes along with therapeutic massage for about 15 minutes, 3 times per week during 4 weeks period. However, control group did not receive intervention during the same 4 weeks. The Balance performance monitor(BPM) was used to measure equilibrium ability. All measurements of each subjects were measured at pre-experiment, after 2 weeks, and post-experiment. Results: The results of this study were summarized below : 1. The sway area of contract-relax exercise group was significantly reduced according to within treatment period(p<.05), most significantly reduced between pre-test and post-test(p<.05). Contract-relax exercise group significantly more reduced than control group(p<.05). 2. The sway path length of contract-relax exercise group was significantly reduced according to within treatment period(p<.05), most significantly reduced between pre-test and post-test(p<.05). Contract-relax exercise group significantly more reduced than control group(p<.05). Conclusion : Contract-relax exercise applied with therapeutic massage can increased equilibrium ability. Additional randomized controlled trials to more fully investigate treatment effects and factors that may mediate these effects are needed.

Objective: The purpose of this study was to examine the main and interaction effects of mothers' parental internal attributions and neuroticism on self-perception of the parental role. Methods: A total of 138 mothers with toddlers in Seoul and other big cities in Korea completed questionnaires, and data were analyzed by Pearson's correlation and multiple regression analyses. Results: The results were as follows: First, mothers who attributed their successful parenting to ability showed lower satisfaction, and mothers who attributed their successful parenting to ability and effort showed higher feelings of equilibrium. Mothers with higher levels of neuroticism showed higher competence, parental investment, and satisfaction in their self-perception of the parental role. Second, there were significant interaction effects between ability attribution and neuroticism on feelings of equilibrium, between effort attribution and neuroticism on feelings of equilibrium, between ability attribution and neuroticism on competence, and between effort attribution and neuroticism on parenting investment. Conclusion: The findings of this research indicate that neuroticism showed a positive effect on self-perception of the parental role because neuroticism indicates sensitivity in parenting. Further, the effects of neuroticism on self-perception of the parental role differed by mothers internal attribution.

The purpose of this study was to investigate the effect of somatosensory input on the gait ability and equilibrium sensory of elderly women. The subjects who participated in this study were 31 elderly women with a mean age of 75 years or older who no using a walking stick and had no abnormality in otolaryngology. The control group consisted of 30 elderly women who did not exercise regularly more than twice a week. Dependent variables consisted of 2.44m timed up and go test, 10m usual gait, 10m fast gait and 6minute gait. The equilibrium sensory test was performed using EquiTest (NeuroCom, USA). The results of the study on gait ability were not statistically significant for 2.44m timed up and go test, and 10m usual gait. However, 10m fast gait (P<.001) and 6min gait (P<.05) showed significant differences. According to the results of the study on equilibrium sensory ability, there was no significant difference between Condition 1 and Condition 5 however Condition 2 (P<.01), Condition 3 (P<.01), Condition 4(P<.01) and Condition 6 (P<.05) showed statistically significant differences. In conclusion, walking stick have beneficial effects on walking and equilibrium sensation, and elderly women need to actively use walking stick when going out and walking.

This study examines the effects of spasticity, equilibrium and gait ability at lower extremity on lumbar stabilization exercise(LSE) with Swiss ball. This experiment was conducted to compare BBS, FRT, MAS and TUG by Swiss ball LSE with 34 stroke patients. equilibrium by BBS or FRT, spasticity by MAS and gait ability by TUG were measured after a 8-week traditional exercise physical therapy(17 subject of stroke patient) and a Swiss ball LSE(17 subject of stroke patient). These result lead us to the conclusion that BBS & FRT were statistically increased and MAS and TUG were decreased on Swiss ball LSE group. there were statistically differential effect between each group on FRT and MAS. These results suggest that Swiss ball LSE has the capability to improve spasticity, equilibrium and gait ability at lower extremity. Consequently, Swiss ball LSE would be lead to restoration of muscle spasticity, equilibrium and gait ability on stroke patients.

In this paper, we present the development of a new training system for equilibrium sense and postural control. This system consists of an unstable platform, a force plate, a computer, and training programs. The unstable platform provides 360 degrees of movement allowing for training in all directions. To evaluate the effects of the training system, we performed various experiments to train the ability of equilibrium sense and postural control of fifteen young healthy subjects. We measured the time a subject maintains his or her center of pressure on a target, the time a subject moves his or her center of pressure to a target, and the mean absolute deviation of the trace before and after the training. We analyzed these parameters obtained before and after the training using paried-sample T-test. The result shows that the subjects experienced distinctive enhancement in their ability of postural control through the training using our system.
