This study suggests a set of Causal Loop Diagram (CLD) of Causality Mechanism which integrates the matter of characteristics of emerging market and its expansion strategies. In order to make CLD more objective, all causalities are articulated from recent 55 studies (2000~2012) of SSCI Top Journals. This approach is valuable in that it is a first try to draw all the causalities from rigorous literature review regarding emerging market strategy. The 5 CLDs will show and clarify the strategies of how to expand into emerging market for MNCs. In sum, political activity and institutional void is a critical factor related to characteristics of emerging market, and CSV and cultural distance should be considered as a leverage point. For all this study's contribution to clarify the causality of emerging market strategies with abundant literature review, the study has its limits in integrating and testing CLD.

The purpose of this study was to development a model of problem solving instruction for improving practical skill-competence in technical high school. For the study, various literature researches were reviewed intensively about problem solving process, laboratory instruction's approaches and learning principals. The problem solving instruction process was composed with identifying problems, generating alternative solutions, investigation and research, choosing a solution, acting on a plan, modeling of problem solving, testing and evaluating, redesigning and improving. The skills schema combines a four domain of skilled activity, that is, cognitive skills, psychomotor skills, reactive skills and interactive skills. The problem solving instruction was composed with five major learning systems-emotional, social, cognitive, physical, and reflective-that can be used extensively as generic lesson plashing. The teacher serves as a coach or guide for student learning. As a facilitator, the teacher challenges, questions, and stimulates the students in their thinking, problem solving and self-directed study. In this process, students represent problem with think aloud, assume responsibility for their learning and move from teacher-centered to student-centered education.

This paper proposes the Train Control System for the LRT(light rail transit). With regard to information processing in car, we build a computer network in the car, turned the hardware required for train control into software, and developed the Train Control Monitoring System(TCMS) and ATC. Drive Type of Train control system car can drive with Driverless mode basically, and this paper applied 10Mbps special communication type for car control, data analysis, The propulsion efforts and breaking effort can control the cars. It is used Vector Control in Propulsion control and proposed Operating pattern for Propulsion control thinking Operating data of Rubber Tire LRT.

Traffic congestion stems from the widespread desires of people to purse certain goals that inevitably overload existing roads every day. he a transportation policy, congestion toll system has been implemented in Seoul, since 1996. The growing concerns on whether the system would achieve sustained results in the future motivated us to investigate the effectiveness of this policy. Developing and running the congestion toll simulation model, we find that this policy is not an effective policy in the long m. The paper indicates the power of system dynamics approach as a tool for evaluating complex policy like a congestion toll, and suggest that city transportation policy maker should approach the problem with systems thinking and analyze the effectiveness of policy on the basis of understanding the dynamic relationships among subsystems.

This paper deals with non-algebraic Kripke-style semantics for three-valued paraconsistent logic: set-theoretical Kripke-style semantics. We first recall two three-valued paraconsistent systems. We next introduce set-theoretical Kripke-style semantics for them.

This paper grasped the labor productivity actual condition by the standard of per unit working hour and production about the main products of our country's industrial the main materials and could understand the average of our country's labor productivity as compared this with the labor productivity actual condition of Japan. As the point at issue of analitical result. 1. Low a matter of thinking about productivity. 2. Have a lot of difficult problem in an industrial part. 3. Have the point at issue on technical development and accumulation. 4. Have the point at issue on management. As a countermeasure about these. 1. must convert the way of use of industrial policy. 2. must make a housing development and special serialization of a small and medium enterprise. 3. must establish an organic technical development system. 4. must grope the policy of management rationalization.

최근 국내외에서 소프트웨어 교육의 중요성이 강조되고 있다. 2015년 개정 교육과정에서도 초 중등생들의 컴퓨팅사고력 계발에 관심이 집중되면서 초 중등학생들을 대상으로 코딩교육이 진행되고 있다. 컴퓨팅사고력 증진을 위해 그 핵심요소인 추상화와 자동화 능력을 신장시킬 여러 방법들이 연구되고 있다. 본 연구에서는 추상화 능력에 대해 교육심리 측면에서 학생들의 프로그래밍 능력 특성을 파악한 후, 컴퓨팅 사고력 계발에 도움을 주고자 한다. 이를 위해 일반계 고등학생들을 대상으로 파이썬 프로그래밍 교육을 보다 용이하게 진행하기 위하여 러플(RUR-PLE) 프로그래밍을 한 학기동안 학습한 후, 학생들의 추상적 사고수준이 프로그램을 이해하는데 어떻게 영향을 미치며 성별 간에 어떤 차이를 가지는지를 분석한다.

Perhaps, one of the typical emerging markets drawing tremendous attention from not only business professionals but also policy-makers would be the mobile Internet services. In recent years many research institutes reported their predictions on the growth of the mobile Internet services market, announcing that the market would show explosive growth and replace the wired Internet service market rapidly. Unfortunately, however, the reality we are facing at present is quite different from their expectations. The realized share of the mobile services in Korea last year has turned out remaining only about one percent of the total network service revenue. What are the reasons for the gap between the prospects and the reality? Starting from this question, this paper attempts to explore the generic pitfalls of the traditional number-crunching methods adopted thus far for the forecast of newly emerging market trends, and present an alternative by introducing systems thinking to the mobile Internet service market as an example, followed by its rationale as a new tool for forecasting and some reasoning about why traditional methods are no longer appropriate.

This paper deals with one sort of Kripke-style semantics for three-valued paraconsistent logic: algebraic Kripke-style semantics. We first introduce two three-valued systems, define their corresponding algebraic structures, and give algebraic completeness results for them. Next, we introduce algebraic Kripke-style semantics for them, and then connect them with algebraic semantics.

This paper deals with the introduction of capstone design project by team activities in Department of Electronics and Communication Engineering, Korea Maritime University. This course is referred to as Creative Engineering Design for spring semester of 4th-year undergraduates. The course focuses on creative thinking and cooperative mind to students by learning engineering design skills, realizing their idea through design project and recognizing practicality of their systems. The intent of the course is to provide a true "capstone" experience, where students can combine their skills to achieve the successful completion of a project. This paper describes class process and evaluation method, and cooperative works with mentees and industrial mentors connected through Hanium network for IT mentoring activities.
