The purpose of this study is to examine major factors that affect patterns of living arrangements of older Korean noncitizens in the United States using the 1990 8% Public Use Microdata Sample(PUMS). In order to do so, I analyzed the effects of four factors including acculturation(English proficiency and Age at migration), economic circumstances(Personal Income and Supplemental Security Income: SSI receipt), health status(Mobility and Personal care limitation), and the ethnic community. The results show that acculturation and economic circumstances play an important role in determining the patterns of living arrangements among older Korean aliens, whereas the health status and the ethnic community do not show consistent effects. Regardless of marital status, the impact of age at migration is positively associated with solitary living of older Korean noncitizens, though, the effect of English proficiency show the opposite direction in accordance with marital status. That is, among nonmarried elders, those who cannot speak English are more likely to live alone. The case is reverse for married elders. The impact of economic feasibility is also positively associated with independent living arrangements. Those who receive SSI are much more likely to live apart from family, and elders whose annual personal income between $5, 001 and $10, 000 have the greatest propensity of solitary living-a large proportion of their income source is SSI. Individuals who receive SSI are also qualified to collect Medicaid, food stamps, rent subsidies, and other welfare benefits. In a sense, the economic feasibility provided by welfare benefits is the key determinant of independent living of older Korean noncitizens. Therefore, the recent welfare reform which denies legal aliens welfare benefits such as SSI and food stamps will severly affect the present living arrangements of older Korean aliens, and give economic burden to their family member The findings also show that there are significant differences within the elderly Korean Americans in terms of demographics, income, fertility, health status, and patterns of living arrangements by U.S. citizenship status. In particular, after controlling for age at migration as a proxy for acculturation, there is a statistically significant variation in living arrangements between elderly Korean noncitizens and naturalized citizens. For both theoretical and methodological reasons, future research on minority aging needs to investigate the concept of U.S. citizenship status for its impact on patterns of living arrangements among the minority elderly.

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.

Objective : The purpose of this study is to find out whether group approach of sensory integration (SI) enhances sensory processing, fine motor function, and social skill for the children with sensory integration disorders. Method : Three children with problems related in sensory integration had got received 21 intervention sessions. We evaluated children with sensory profile(SP), social maturity test, Korean-developmental test of visual perception(K-DTVP), Bruininks-Oseretsky Test of Motor Proficiency(BOTMP) before-and after intervention. The statistical significance of data is tested by the Wilcoxon matched-pair signed rank test. Results : All data of post-intervention did not show any statistically significant differences; SP, social maturity test, K-DTVP, BOTMP. Conclusions : This study is to verify the effect of group SI intervention on sensory processing, fine motor function, and social skill for children with sensory integration disabilities. The results were not statistically significant. However, the average score after SI intervention has been improved in the section of fine motor and social skill comparing to that of pre-intervention period. It would have positive impact for children with sensory integration disabilities. It is needed to study with the larger number of target children and more often treatment session are suggested. The confounding variables also should be controlled in the further study.

Analysis of combat effectiveness is required to consider the concept of tactical cooperative engagement between manned-unmanned weapon systems, in order to predict the required operational capabilities of future weapon systems that meets the concept of 'effect-based synchronized operations.' However, analytical methods such as mathematical and statistical models make it difficult to analyze the effects of complex systems under nonlinear warfare. In this paper, we propose a combat simulation model that can simulate the concept of cooperative engagement between manned-unmanned combat entities based on wireless communications. First, we model unmanned combat entities, e.g., unmanned ground vehicles and drones, and manned combat entities, e.g., combatants and artillery, considering the capabilities required by the future ground system. We also simulate tactical behavior in which all entities perform their mission while sharing battlefield situation information through wireless communications. Finally we explore the feasibility of the proposed model by analyzing combat effectiveness such as target acquisition rate, remote control success rate, reconnaissance lead time, survival rate, and enemy's loss rate under a small-unit armor reconnaissance scenario. The proposed model is expected to be used in war-game combat experiments as well as analysis of the effects of manned-unmanned ground weapons.

Objectives：This study was done as a part of investigating individual and socioenvironmental factors affecting test anxiety in adolescent. The focusing of this study was detecting specific family enviromental factors affecting worry and emotionality of test anxiety. Methods：The subjects of this study were 880 middle and high school students in Seoul, Korea. To evaluate test anxiety level, Spielberger's Test Anxiety Inventory was applied and to evaluate familial factor, Moos and Moos' Family Environmental Scale was done. Results：The results were as follows. 1) Total and worry part of test anxiety scores were negatively correlated with cohesion and independence scores. Total, worry, and emotional part of test anxiety scores were positively correlated with achievement orientation and control scores. 2) High test anxiety group showed higher achievement orientation and control scores, and lower cohesion scores than low test anxiety group. 3) The higher socioeducational level of parents were, the higher three subscale (cohesion, independence, and achievement orientation) scores were, except control score. Conclusion：In therapeutic approach of adolescent's test anxiety, the importance of education and treatment of their parents should be emphasized. Parents should set their children's appropriate achievement goal, encourage their children's independency instead of control. Cohesion of familial members are also needed.
