The purpose of this paper id to study the factors influencing MIS user satisfaction. For this purpose. I have reviewed the results of past studies on the performance factor of MIS, and introduced a new model associated with small & Medium Business. On the basis of this model, I have hypothesized that the following variables influence user satisfaction : (gender, age), individual characteristics(user attitude, training for user), managerial characteristic(top management involvement, organizational support) and task characteristics(task structure). There were 195 participants surveyed using questionnaires from 25 different small & medium Business in Pusan. The research model and associated hypotheses were tested by following statistical techniques: reliability test, regression, t-test and ANOVA. The findings of this study are follows; 1. It was found that gender and age are not correlated user satisfaction. 2. Among individual characteristics, only user attitude influence user satisfaction significantly. 3. While organizational supports influence positively user satisfaction, top management involvement do not influence it. 4. Task structure is highly correlated with user satisfaction. In spite of many factors affecting MIS success, this study did not consider all variables affect on user satisfaction. We need integrated model including more various factors.

This paper describes the optimal sizing of each component using computer simulation and presents the efficient operating scheme of series HEV using hardware simulator, the equivalent system. As the sizing method of components have been experimental and empirical, it is needed to spend much time and development cost. however, the results of computer simulation will set the optimal sizing of components in short time. There are two type of driving control, power-tracking mode and load-levelling mode, ill series HEV. This paper presents that series HEV be operated ill the load-levelling mode which is more efficient than power-tracking mode.

The 『Naegyeongseupyubangron(內經拾遺方論)』, written by Nakyonggil(駱龍吉), is an ancient book of Bangron(方論). The exact time period of this book is unknown. To estimate its written time, we compared the contents of this book to other sources on the cause of diseases, the description of symptoms, the transmission of diseases, and treatments. In addition, we analyzed the features of the book by comparing it to other books of Bangron(方論). As a result, we estimated the approximate time period that it was written and gained a better understanding of the ancient medicine. We reached several conclusions through this study. 1. The approximate time period of『Naegyeongseupyubangron(內經拾遺方論)』is that of the Southern Song(南宋) dynasty of China, probably after『Saminbang(三因方)』between 1174 and 1279. 2. Nakyonggil(駱龍吉) was influenced by Wangbing(王冰), Sonsamak(孫思邈), Yuhagan(劉河間), Jinmutaek(陳無擇). and he influenced 『Uibanggo(醫方考)』. 3. The 『Naegyeongseupyubangron(內經拾遺方論)』 is the most comprehensive book among the books of Bangron(方論) because of its analysis of the 『Hwangjenaegyeong(黃帝內經)』 and its connection to the treatment of ancient diseases in Oriental Medical History.

In this paper, the empirical study for a hybrid generation system based on wind power which is leading renewable energy was performed. The simulation for the overall operation of the wind generator, diesel generators, monitoring system and a central controller operated in Demonstration Complex was carried out. In addition, the adequacy of the control algorithm was examined through the experiments.
