Recently there are many development and support policies for start-up companies because of successful venture companies related to ICT services. However, as these policies have focused on the support for the initial stage of start-up, many start-up companies have difficulties to continuously grow up. The main reason for these difficulties is that they recognize start-up tasks as independent activities. However, many experts or related articles say that start-up tasks are composed of related processes from the initial stage to the stable stage of start-up firms. In this study, we models the start-up processes based on the survey collected by the start-up companies, and analyze the start-up process of ICT service companies with process mining techniques. Through process mining analysis, we can draw a sequential flow of tasks for start-ups and the characteristics of them. The analysis of start-up businessman, idea derivation, creating business model, business diversification processes are resulted as important processes, but marketing activity and managing investment funds are not. This result means that marketing activity and managing investment funds are activities that need ongoing attention. Moreover, we can find temporal and complementary tasks which could not be captured by independent individual-level activity analysis. Our process analysis results are expected to be used in simulation-based web-intelligent system to support start-up business, and more cumulated start-up business cases will be helpful to give more detailed individual-level personalization service. And our proposed process model and analyzing results can be used to solve many difficulties for start-up companies.

Huge growth in developmental level, new accomplishment, and The period of adolescents is not only the transition stage but also improvement of academic level. In this level of stage, adolescents have difficulties in development, so they show psychological abnormality such as stress and depression. They could develop mental disorder such as depression or anxiety if they do not overcome the abnormality. According to the situation of the insufficiency of the decent program for adolescents' mental health in the current society, we are strongly requested to develop the psycho-therapeutic program for them. Therefore, in this study, we examined the effect of the musical activities as blues music structure on the improvement of the Self-Efficacy in the female middle school students who have depressive tendencies as well as what they experienced through the activities. The 3 participants were selected out of 70 students in the first year at the "D" middle school in Seoul by being tested with Child Depression Inventory(CDI) and Self-Efficacy Scale(SES). The musical activities were built with 3 steps. Of which, the first one was the introduction to each other, the formation of rapport, and induction of their interests to the musical activities through blues. The second one was letting participants learn the blues music structure by practice and play assigned music(including improvisation) during later 5 sessions with different difficulties at each session. The third one was giving them opportunities to play a music out of the acquired ones during the session or creative music by their own, which results in maximizing musical activities and an acquired experience. As a result, first of all, the scores of CDI test of 3 participants in 10 time sessions showed slight changes, suggesting the negative correlation between CDI and SES even though changes were not big differences. Secondly, the scores of SES test of 3 subjects in 10 time sessions were all changed and especially preference for tasking was significant. Thirdly, the scores of SES for musical playing test of 3 participants in 10 time sessions were all changed and especially preference for musical tasking was significant shown. Finally, according to answers of 3 participants in 10 time sessions for the after questionnaire on musical activities, participants experienced affirmative self-confidence and positive emotion. Taken together, it was suggested that musical activities using blues music structure could be promising therapeutic intervention method.

In this paper, a mechanism of an omni-directional personal mobility which can drive diagonally is proposed. Mobility is a prerequisite involved in basic human life and activities. Personal mobility vehicle is a new mobility method which overcome the limits of automobiles. However, personal mobilities with four wheeled structure still have limitations. The proposed personal mobility vehicle can overcome the limitations of mobility because its rear wheels can be steered omni-directionally. In addition, the handicapped can drive it through a narrow road such as an alleyway or corridor and avoid obstacles on the traveling route. The proposed mechanism of personal mobility and the steering performance are tested by experiments, and the feasibility of diagonal driving is verified.

This study was to investigate how the underachievers of mathematics in a non-leveling excellent high school would overcome the errors through the lessons based on the inductive thinking model in the equation of a circle. The results showed that when there were many stages to solve the problem, the students gave it up or forgot the stage they reached. In this case, if they had a revisit-opportunity to review their thinking process by planning ahead the stage to solve the problem and recording it, the omission error of the solving process and the error of wrong conclusions would be dramatically decreased. Moreover, they understood the mathematical concept, principle, and formula and remembered the learning contents extremely well through thinking by themselves in exploration-based activities and by using visualization for the problem and could solve the problem through these pictures besides algebraic expressions.

This study is an attempt to analyze the individual merit of the INSTRAT model, which forms a cognitive process paradigm, and that of the Big6 model, which involves a functional approach, as tools for enhancing human information activities and aptitude. The former was examined through logical interpretations, while the latter was deduced from interviews using the Micro-Moment Time-Line method, a key methodology used in the Sense-Making Approaches. Results indicate that the application of the INSTRAT model is suitable for developing information systems that can assist users in the stage of defining information needs and search strategies, and that the application of the Big6 model is appropriate in information literacy education or information aptitude training. Of particular significance is the fact that the study proves for the first time that human information problem-solving behavior indeed follows the process delineated in the Big6 model.

As Electronic Commerce(EC) has been emerged and has developed, many researchers have tried to establish EC framework for automated contract and negotiation using agent technologies. Traditional researches, however, often had limitations. They often enforced the user's participations during the automated contract process of agents. They also could only consider a few of the user's requirements for a specific goods and did not have supported the procedures and methodologies for making the best contract. In this paper, we propose business model on EC based on multiagents to overcome the defects of the previous researches. We apply CSP techniques to brokerage process to satisfy various preferential requirements from the user. We also propose efficient negotiation mechanism using negotiation model of game theory. The contract candidates automatically negotiate and mediate in terms of their benefits through the proposed negotiation mechanism. For the optimal brokerage and automated negotiation, the agents process activities for contract on three layers, which are called competition layer, constraint satisfaction layer and negotiation layer in the proposed model. We also design the message driven communication protocol to support the automated contract among the agents. Finally, we have implemented prototype systems applying the proposed model and have shown the various experimental results for efficiency of the proposed model.

This is a case study on two schools practising integrated science education (hereafter ISE). The purposes of this study are to investigate the types and features of ISE in the schools actively practising ISE, to identify the contextual factors of the schools, and to give implications for implementing ISE in schools. This study investigated the contextual factors in practicing ISE with a focus on the two schools, a middle school in Gyeonggi-do and a high school in Busan. They were breaking down the boundaries among teaching subjects and providing student-oriented instruction with problems in the real world. The data were collected by observing classes, by interviewing teachers, and by reviewing school documents and students' reports. The research findings are as follows: first, the two schools took part in ISE actively. They teach science to students providing integrated experiences mainly by using interdisciplinary knowledge and/or by solving the problems pertaining to the real world. While the former integrated subjects centering on topics, the latter focused on a project-based learning driven by students. They have differences in regard to the role of teachers and students, the level of integration and the type of integration. Second, the contextual factors that enabled ISE to be implemented there were found. The previous studies revealed six contextual factors in practising ISE: small and stable learning environment, leadership, team activities, in-school planning time, flexible timetable and community links. This study also found similar factors. However, the cases of this study provided ISE on a large scale and in a short period of time, instead of a small and stable learning environment. Teachers viewed the process of ISE not only as a tool to overcome the conservative culture of teachers but also as a pursuit of innovation.
