For the successful implementation of IT projects, individual consultant's competency in the project is very important. Especially, 3 key factors which are 1) Learning-by-Doing, 2) Learning-from-Others, and 3) Learning-by-Investment with individual consultant's competency, are required for solving various critical issues which can be occurred during implementing IT project. The objective of this research is to examine the effects of these learning processes on decision performance of consultants. Prior to setup the research model, we conducted 3 times in-depth interviews with IT consultants who have over 20 years IT project experiences. Through interviews with IT project expert, we tried to validate our research model and develop survey questionnaires. Over 100 consultants, who are working at SI companies those of Samsung SDS, LG CNS, SK C&C and other small SI companies, were participated to survey. In the contrary of our thoughts before conducted experiment, we got the interesting result from pilot experiment. Most influenced learning process was Learning-by-Doing and less influenced learning process was Learning-from-Others.

This study proposes basic information to make effective environments for social welfare education, revealing the reasons why students choose the social welfare major at Konyang Cyber University. We conducted qualitative research with 41 students in the social welfare department at Konyang Cyber University. The result of this research is as follows. First, most students chose their major to get a certificate that can benefit them in the near future. Second, they chose their major as a way to achieve renown, and to enhance the quality of their lives. Third, they desired to contribute to society through their social work. Finally, individual experiences and family background were also motives. Based on the research, to improve learning outcomes in social welfare education, the necessary learning strategies are as follows. First, goal-oriented learning is necessary for students who want to get the certificate. A practical curriculum needs to contain both practical skills and professional knowledge applicable to the social work field. Second, education for students who choose the major to gain fame, and to develop their lives, requires generation-integrated education to help them review their lives and find their own meaning in life. Third, education for students who choose the major for a practical social contribution has to contain volunteer training that can lead them to be professional volunteers in society. Fourth, education for students who choose the major based on their personal experiences and their family background needs to deal with case management, which discovers the recipients who need help in society and the students who can achieve visible outcomes after all.

The purpose of this study is to find out whether G-learning method can raise students' academic motivation of the mathematics in elementary school. The subjects were 687 students in the same school. They were divided into two groups, control group and experimental group. Written tests were taken before and after the semester to evaluate the students' motivation of the mathematics. According to the results, the participation in G-learning program improved their academic achievements of mathematics. Experimental group showed statistically significant improvement in intrinsic motivation. On the contrary, control group showed statistically significant improvement in extrinsic motivation. This means that G-learning method make students study mathematics on their own initiative.

By the help of expansion of computer network and rapid growth of Internet, the information infrastructure is now able to provide a wide range of services. Especially open architecture - the inherent nature of Internet - has not only got in the way of offering QoS service, managing networks, but also made the users vulnerable to both the threat of backing and the issue of information leak. Thus, people recognized the importance of both taking active, prompt and real-time action against intrusion threat, and at the same time, analyzing the similar patterns of in-trusion already known. There are now many researches underway on Intrusion Detection System(IDS). The paper carries research on the in-trusion detection system which hired supervised learning algorithm and Fuzzy membership function especially with Neuro-Fuzzy model in order to improve its performance. It modifies tansigmoid transfer function of Neural Networks into fuzzy membership function, so that it can reduce the uncertainty of anomaly intrusion detection. Finally, the fuzzy logic suggested here has been applied to a network-based anomaly intrusion detection system, tested against intrusion data offered by DARPA 2000 Intrusion Data Sets, and proven that it overcomes the shortcomings that Anomaly Intrusion Detection usually has.

Creativity is the most important characteristic and ability in the 21st century. Recently leading people in Korean society are aware of the significance of the enhancement of the creativity. However, Korean students are less likely to take initiative or depart from standard ways of thinking or doing things, because Korean Confucius culture puts an emphasis on collectivism. An individual has an obligation to conform in order to avoid conflict and maintain social harmony. The rule of respecting parents and teachers leads to a lack of self-expression and entails silence. Brainstorming technique developed by American Osbron, who originated the group brainstorming in 1953, is the most popular creative thinking method for the students. Brainstorming technique has two principles : ideation can be more productive if criticism is concurrently excluded; The more ideas the better. In doing BS, each panel should consist of chairperson, an assistant chairperson, recorder, and 10 others including 2-3 females. However there are several problems in doing group BS, such as production blocking, uniformity thinking, evaluation apprehension, and social loafing. This study was undertaken to investigate the proper way of forming Brainstorming groups with Korean students according to the Sasang Constitutional Medicine originated by Korean Lee Je-ma in 1894. Human beings are classified in four group in Sasang Constitutional Medicine : Taeyang-In, Teaum-In, Soyang-In and Soum-In. Two Yang-Ins are more self-expressive : Taeyang-In has very unique ides and thoughts; Soyang-In is very humorous and like to present his/her ideas. On the other hand, two Um-Ins are passive and are not likely to speak out their ideas in group. Therefore, in this investigation firstly, the brainstorming group was formed with two Yang-Ins (Taeyang-In and Soyang-In) and two Um-Ins(Taeum-In and Soum-In) separately and secondly, Yang-Ins and Um-Ins were mixed. And the first method was compared with the second method in terms of the degree of participation of the group members and finally the better grouping method to produce more and better ideas was discussed and suggested for the educational system.

With the five-day workweek system in bank and the increased usage of ATM(Automatic Toller Machine), it is required that the financial crime using stolen credit card should be prevented. Though a CCTV camera is usually installed in near ATM, an intelligent criminal can cheat it disguising himself with sunglass or mask. In this paper, we propose facial feature verification system which can detect whether the user's face can be Identified or not, using image processing algorithm and SVM(Support Vector Machine). Experimental results show that FAR(Error Rate for accepting a disguised man as a non-disguised one) is 1% and FRR(Error Rate for rejecting a normal/non-disguised man as a disguised one) is 2% for training data. In addition, it shows the FAR of 2.5% and the FRR of 1.43% for test data.

A Case Study on Venture and Small-Business Executives' Use of Strategic Intuition in the Decision Making Process This paper is a case study on how Venture and Small-Business Executives managers can take advantage of their intuitions in situations where the business environment is increasingly uncertain, a novel situation occurs without any data to reflect on, when rational decision-making is not possible, and when the business environment changes. The case study is based on a literature review, in-depth interviews with 16 business managers, and an analysis of Klein, G's (1998) "Generic Mental Simulation Model." The "intuition" discussed in this analysis is classified into two types of intuition: the Expert Intuition which is based on one's own experiences, and Strategic Intuition which is based on the experience of others. Case study strategic management intuition and intuition, the experts were utilized differently. Features of professional intuition to work quickly without any effort by, while the strategic intuition, is time-consuming. Another feature that has already occurred, one expert intuition in decision-making about the widely used strategic intuition was used a lot in future decision-making. The case study results revealed that managers were using expert intuition and strategic intuition differentially. More specifically, Expert Intuition was activated effortlessly, while strategic intuition required more time. Also, expert intuition was used mainly for making judgments about events that have already happened, while strategic intuition was used more often for judgments regarding events in the future. The process of strategic intuition involved (1) Strategic concerns, (2) the discovery of medium, (3) Primary mental simulation, (4) The offsetting of key parameters, (5) secondary mental simulation, and (6) the decision making process. These steps were used to develop the "Strategic Intuition Decision-making Model" for Venture and Small-Business Executives. The case study results further showed that firstly, the success of decision-making was determined in the "secondary mental simulation' stage, and secondly, that more difficulty in management was encountered when expert intuition was used more than strategic intuition and lastly strategic intuition is possible to be educated.
