In this paper, we propose a personal-computer-based wireless data access system, which used direct sequence spread spectrum method and the ISM band with 2.44GHz radio frequency. By applying bi-directional transmission between wireless handy terminals and PC or servers, it can be effectively connected with any kinds of database systems such as Oracle, MS-SQL and Access. Therefore it could economically be used as peripheral equipments for ERP or SCM system.

Systems are often operated by not integration but blocking, i.e., non-standardization. The system blocking is mainly caused by non-standardization or incompatibility. The integrated system is effective, but researches for quantification of effectiveness from integrating system are few. System blocking causes additional cost which is almost intangible and potential. In this paper we proposed a model to quantify the effectiveness of system integration. To verify the validity of proposed model, we applied the model for Korean information and communication industry and forecasted the cost of integration for South and North Korean telecommunication industry in the way of three scenarios.

Objective : The purpose of this paper was to study the effect of involved upper extremity’s motor function recovery on Activities of Daily Living in subject with hemiplegia by using Fugl-Meyer Assessment (FMA) as a motor recovery test and Functional Independence Measure (FIM) as a functional test.Method : The subjects of the study were 20 stroke patients who were admitted in KeiMyung University Dongsan Medical Center from November, 2002 to April, 2003. Data were analyzed for wilcoxon signed-rank test, mann-Whitney U test, spearman’s rho using SPSS/PC+ program. Result : The results of the study was as follow;1. Involved upper extremity’s motor function and independence of ADL is significantly differ-ence after occupational therapy(p<.05).2. Involved upper extremity’s motor function recovery is not significantly correlated in-dependence of ADL. but, motor FIM and FMA is significantly correlated after occupational therapy(r=.461).3. Involved upper extremity’s motor function recovery is significantly difference in lesion site and not significant difference in sex, involved side (p<.05).4. Independence of ADL is not significant difference in lesion site, sex, involved side(p>.05).Conclusion : The results suggest that lesion site maybe a factor to predict involved upper extremity’s motor recovery and require various occupational therapy program according to lesion site.
