The purpose of this study is to explore which factors influence the performance of computer practice-education in vocational high schools. We collected 604 response data from total 7 vocational high schools in Seoul City to test empirical analysis using SEM(Structural Equation Modeling) frequently used in social-science area. According to our results, all independent variables(learner's response learner's motivation, learner's attitude, learning contents, intention to learn, learner's ability and learning behavior) were found positively influencing learning performance of students. Based upon them we contributed our research model to combine TRA theory in psychology with Holton theory for academic implications. And also, from the perspective of practical implication, we can expect that our results will provide some useful guidelines for operating effective computer-practice education.

A 4-level baroclinic numerical model is designed by using the vorticity equation and Omega equation. Block-Cyclic-Reduction method is applied to the solution of the Helmholtz defferential equation, which is proved to be better than the Relaxation method from the composite viewpoint of accuracy, stability and economy. It was investigated whether the model explains the physical process influenced by voricity and temperature advection. It was also examined if the model atmosphere describes the general circulation. This examination is similar to Phillips(1956). The result of this numerical experiment shows that the model explains qualitatively the Quasi-Geostrophic theory for the development of Baroclinic wave, as throughly described in Holton(1972).
