The present research aimed at investigating the impacts of volunteer activities on self-development and sociability-development. In study 1, the scale comprised of 15 items was developed to measure the meaningfulness of volunteer activities. An exploratory factor analysis was conducted on the data obtained from 428 undergraduates (193 males and 235 females). A confirmatory factor analysis was then conducted on the data obtained from 280 undergraduates (124 males and 156 females). In study 2, the impacts of volunteer activities on 947 undergraduates (461 males and 486 females) were analyzed in terms of self-development and sociability-development. Self-development consisted of self-evaluation, self-esteem, and quality of life. Sociability-development consisted of pother-acceptances, sense of community, and democratic citizenship. The results showed that not more volunteer activities itself but more meaningfulness of those activities had stronger relations with self-development and sociability-development. Finally, a values of the undergraduates internalized for volunteer activities and their levels of self-development and sociability-development expectation were discussed.

Teachers' questioning plays an important role in mathematics teaching and learning by asking students to react or to participate in mathematical discourse. Previous studies on teachers' questioning have not focused on how to questioning to formulate an effective mathematical discourse which is contributed by students because studies mostly analyzed and categorized teachers' questions according to cognitive levels of questions without consideration of context. Therefore, this study explored characteristics of teachers' questioning to formulate an effective characteristics of teachers' questioning to formulate an effective mathematical discourse in mathematics classrooms. By reviewing and analyzing mathematics discourse and studies on teachers' questioning theoretically, we presented openness, sharedness, and productivity as characteristics of teachers' questioning. Through a middle school mathematics teacher's case, we examined three characteristics were necessary to formulate an effective mathematical discourse. Based on results from theoretical analysis and case analysis, we discussed that openness, sharedness, and productivity would be useful as a framework to analyze teachers' questioning.

In this paper, We proposed the approach of GPU and motion vector to analysis the Human activity in real-time surveillance system. The most important part, that is detect blob(human) in the foreground. We use to detect Adaptive Gaussian Mixture, Weighted subtraction image for salient motion and motion vector. And then, We use motion vector for human activity analysis. In this paper, the activities of human recognize and classified such as meta-classes like this {Active, Inactive}, {Position Moving, Fixed Moving}, {Walking, Running}. We created approximately 300 conditions for the simulation. As a result, We showed a high success rate about 86~98%. The results also showed that the high resolution experiment by the proposed GPU-based method was over 10 times faster than the cpu-based method.

The purposes of this study is to examine the effect of fitness among entrepreneurship, dynamic capabilities and innovation activities on business performance. A survey was conducted and analyzed on small & medium manufacturing companies in Korea with the following result of the study. First, the fitness of entrepreneurship and dynamic capabilities, the fitness of dynamic capabilities and innovation activities, the fitness of entrepreneurship and innovation activities have a significant effect on business performance respectively. Second, the fitness of all the three variables also has a significant positive effect on the performance. Additional path analysis shows that dynamic capabilities and innovation activities have mediating roles between entrepreneurship and business performance. The results imply that not only each of the entrepreneurship, dynamic capabilities, and innovation activities has a positive effect on business performance but also the three factors in harmony have a synergic positive effect on the business performance.

It is the aim of this paper to find the requisites for the target problem solving process in reference to the base problem and to search the roles of those. Focusing on the structural similarity, analytic activity and comparative activity in stage of similar mathematical problem solving process, we tried to find the roles of them. We observed closely how four students solve the target problem in reference to the base problem. And so we got the following conclusions. The insight of structural similarity prepare the ground appling the solving method of base problem in the process solving the target problem. And we knew that the analytic activity can become the instrument which find out the truth about the guess. Finally the comparative activity can set up the direction of solution of the target problem. Thus we knew that the insight of structural similarity, the analytic activity and the comparative activity are necessary for similar mathematical problem to solve. We think that it requires the efforts to develop the various programs about teaching-learning method focusing on the structural similarity, analytic activity and comparative activity in stage of similar mathematical problem solving process. And we also think that it needs the study to research the roles of other elements for similar mathematical problem solving but to find the roles of the structural similarity, analytic activity and comparative activity.

Despite the rapidly increased concern on the circularity of the program development activities in the social service agencies, there are only a few studies about the phenomena. This study is to describe the characteristics of program development in the process of adopting, developing, and disseminating the social programs and to figure out the factors influencing differences in the 3 activities in social service agencies. The researchers constructed an explanative model including each 12-13 independent variables with 3 consecutive dependent variables on the basis of reviewing the related literatures. A multiple regression analysis was applied to predict the features of the program development using 195 questionaries responded from social workers in community service centers. As the result of the descriptive analysis, the two noticeable features are found; (1) the agencies have very actively adopted outside programs, developed appropriate programs for the agency, and disseminated the programs into other agencies in the community. (2) there are some positive aspects of the factors in related to the process of the program development. The results of the regression analysis show that the three dependent variables of the adoption, development, and dissemination are very closely interconnected with each others, showing the evidence of the circularity in the agencies. In addition, the 5 independent variables at the value of p .01 are statistically related with the circularity of the three dependent activities. The implication of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.
