The objectives of this study was to analyze and solve the relationship between IT investment and the performance of the company using IO model suggested by Marchand et al, 2001. In this study, we first tried to investigate the cognition and importance level of the SME's CEO through the survey. Using survey results, we extracted 6 research variables from 15 IO variables and analyzed how the performance of the company have been affected by these variables. We birefly summarized as follow. The CEO of the SMEs only considered TIR as critical resources among IT resources irrespective of the important contribution of human IT resources to company's performance. Also they did not recognize the effective information use by people led to key behaviors and values.

This paper proposes the gait phase classifier using backpropagation neural networks method which uses the angle of lower body’s joints and ground reaction force as input signals. The classification of a gait phase is useful to understand the gait characteristics of pathologic gait and to control the gait rehabilitation systems. The classifier categorizes a gait cycle as 7 phases which are commonly used to classify the sub-phases of the gait in the literature. We verify the efficiency of the proposed method through experiments.
