The purpose of this paper is to evaluate the policies for reducing private tutoring expenditure in Roh Mu Hyun and Lee Myeong Bak Government using Causal Loop analysis based on the Systems Thinking perspective. The results are as follows. First, high educational achievers receive more private tutoring than lowers and children who have rich parents have better chance to take private tutoring than the others. It reflects the social characteristics which emphasize the academic ability and educational background. Second, two governments implemented educational policies to control the private tutoring expenditure as balancing loops ; strengthening public education, providing after school programs and EBS KSAT teaching and improving the entrance exam of university. Third, they overlooked the unintended feedback loops coming from 1) incongruity between causes and countermeasures of shadow education 2) wrong perception of substitutional relationship between public education and shadow education 3) side effect of the policy increasing the weight of student record 4) problems of diversifying high schools 5) dilemma of easing the burden of testing through admission officer system. The conclusion is that policies of reducing the private education expenses have failed because two governments don't consider unintended Feedback Loops in the process of making education policies. So we have to make policies based on Systems Thinking and reducing private education expenses should not be the purpose of strengthening the public education.

The Korean defense industry was brought up in the government policy since 1970's. The important parts of defense industrial technologies have not been developed, and usually introduced from overseas. Moreover, the development of advanced technologies was not actively stimulated or pursued, consequently shaping the current structure of the defense industry which lacks global competitiveness due to the dearth of high technologies necessary for high-technology weapons. This research analyzes the systems of the Korean defense industry through a systems thinking approach in order to understand the whole mechanism and to find ways to improve the defense industry. Finding some leverages is the main purpose of systems thinking, that yields desirable results with a little effort. The three policy leverages are: (1) the policy for timely fielding; (2) the R&D investment for development and production of domestic high-technology weapons; and (3) the policy measures for exports. The research findings will contribute to the invigorating and developing the Korean defense industry by providing policy-makers and acquisition practitioners with systematic understanding and insight into the dynamics of the defense industry for them to make and execute efficient policies taking into account the Korean overall defense industry.

This study structurally analyzes major inefficiency of Korea's healthcare delivery system by utilizing the systems thinking. In particular, the phenomenon of patient's concentrated visits to large hospitals, waste of resource due to competitions between clinics and large hopitals, and the structure of oversupply were visualized using the causal loop diagram. The inefficient structure of healthcare delivery system can be understood more clearly by utilizing the major system archetypes of 'success to the successful', 'tragedy of commons', 'escalation' and 'limits to growth'. This study also finds solution from archetypal structure suggested by Wolstenholme. The inefficient status of healthcare delivery system might be explained by the 'out of control' archetype. In conclusion, the public resources such as the national health insurance need to be acknowledged as the entire achievement. All the participants should cooperate with each other in order to improve the inefficiency of the healthcare delivery system. In addition, the arrangement of incentive system for cooperation, acceleration of health information technology, and development of innovative business models make the sustainable healthcare delivery system.

This study aims to understand how and why each stage of capitalism grows and changes into the new direction in the moment of crisis, based on the systems thinking approach through the causal loop feedback structure. To achieve the research purpose, it classifies the evolution process of the capitalistic economic system into 4 types: Capitalism 1.0(Classical Laissez-Faire Capitalism), 2.0(Revised Capitalism), 3.0(Neo-liberalism), and 4.0(New Capitalism for the Future). This study focuses particularly on by which feedback structure the growth, crisis, and new transition of capitalism could be explained. The main research results are as follows. The intended positive feedback structure caused the growth at each early stage of capitalism. After that time, as a result of the uncontrolled growth, the negative feedback structure controlling its growth operated on the one hand, while the positive feedback structure amplifying the crisis did on the other hand. The study suggests the Resilient Capitalism as the new evolutional direction of Capitalism 4.0. It can contribute to strengthening its resilience by which all the economic players can recover promptly and flexibly from the crises such as the failure of competition and unemployment.

South Korea has the defense burdensharing agreement with the United States in reference to the U.S. troops stationed in Korea since 1991, based on Special Measure Agreement(SMA). Due to the growth of Korea's economic power and the U.S. provision of the security environment on Korean penninsula, the U.S. government steadily demanded the rise of contributions to common defense from South Korea and South Korea accepted most of the U.S. requests without proper principles of negotiation concerning the cost sharing. This paper analyzes the systems of the Korea－U.S. cost sharing program through a systems thinking, that yields desirable results with a little effort. The three policy leverages are: 1) the development of negotiation principles; 2) the policy making closely linked with National Defense Reform Basic Plan; 3) the policy making with responsibility burdensharing than cost burdensharing. This paper findings will contribute to the developing the Korea－U.S. cost sharing program by providing policy－makers and policy-practitioners with systematic understanding and insight into the dynamics of the program. Also, this will enable the program to execute more effectively with a concrete formula.

This study aims to explore the new paradigm of regional development strategy with the theory of Resilience. Resilience can be defined in terms of a set of interacted capacities to absorb and adapted to different kinds of shocks and disturbance at the regional level. This study focuses particularly on the interaction of component of resilience with the context of regional development strategy. As a result of the Systems thinking approach about dynamic interactions between resilience components and regional problems, this study find that there are many feedback structures which is need for a better understanding of the complex regional resilient development system. This study suggests that the Archytypes of resilience-focused strategy of regional development, which could help achieve an evolution for regional community and people to adapt and bounce back from crisis.

Objective: The purpose of this paper is to introduce new research trends of human error and accident modeling and to suggest future promising research directions in those areas. Background: Various methods and techniques have been developed to understand the nature of human errors, to classify them, to analyze their causes, to prevent their negative effects, and to use their concepts during design process. However, it has been reported that they are impractical and ineffective for modern complex systems, and new research approaches are needed to secure the safety of those systems. Method: Six different perspectives to study human error and system safety are explained, and then seven recent research trends are introduced in relation to the six perspectives. The implications of the new research trends and viable research directions based on them are discussed from a cognitive systems engineering point of view. Results: Traditional methods for analyzing human errors and identifying causes of accidents have critical limitations in complex systems, and recent research trends seem to provide some insights and clues for overcoming them. Conclusion: Recent research trends of human error and accident modeling emphasize different concepts and viewpoints, which include systems thinking, sociotechnical perspective, ecological modelling, system resilience, and safety culture. Application: The research topics explained in this paper will help researchers to establish future research programmes.

4차 산업혁명 시대가 도래함으로써 수많은 영역에 다양한 소프트웨어의 고품질화가 필수적이다. 특히 비전공자 및 기초 전공자들에게는 창의적 사고 기반으로 코드 할 수 있는 능력이 요구된다. 하지만 문제는 창의적 사고 기반의 소프트웨어에 대한 정의 및 아이디어가 부족하다는 것이다. 또한, 비전공자 및 기초 전공자를 위한 코딩 교육 영역에서, 창의적 사고 기반 디자인씽킹과 코딩화는 괴리가 존재한다. 즉 실질적으로는 창의적 사고기법을 통해서 소프트웨어 설계 및 코딩이 가능해야 한다는 점이다. 이런 문제를 해결하기 위해, 창의적 사고 기법과 소프트웨어 개발 프로세스 기법의 접목을 통해 비전공자의 소프트웨어공학 개념 없이도, 디자인씽킹 메커니즘 기반의 코드 템플릿을 제시한다. 이를 통해 창의적 설계의 코딩화를 기대한다.
