Objective: The purpose of this study is to grasp the fundamental structure of incident occurrence in nuclear organizations based on system thinking, and analyze how various causes are interrelated in terms of the causal loop diagram. Background: The recent domestic and overseas nuclear power plant-related incidents and accidents are directly or indirectly associated with safety culture, and thus effective plans for the improvement of safety culture are being called for. While the safety of a nuclear power plant is highly dependent upon technology and equipment, the utilization, maintenance and inspection of the technology and equipment are conducted by workers of the nuclear power plant. Method: Methodology of system thinking perspective using causal loop analysis. Results: As a result of the analysis, first, it turned out that the fundamental cause of incident occurrence in nuclear organizations is time constraint. Second, if a workload of workers increases, their adherence to regulations and procedures comes to be reduced due to time constraint. Third, it is needed, through organizational learning education, to increase actions made from thoughts considering safety as the utmost priority in advance. Fourth, it is necessary to improve professionalism by enhancing educational programs for new workers, and to develop various scenarios with which they can cope with certain situations. Application: This paper provides a base for system dynamics simulation model for future study.

With emphasis on the importance of systems thinking for the establishment of learning organization, Senge in his famous book "The Fifth Discipline", explains in depth four disciplines such as personal mastery, mental models, shared vision, team learning, which are all geared up to the implementation of learning organization. However, two critical pitfalls are found: First, a holistic picture is absent in his presentation of learning organization, which just seems like a puzzle with linking pieces missing between disciplines. Secondly, as is often the case too much details are discussed in expense of insights on each discipline. This paper thus attempts to draw core metaphysical insights underlying Senge's learning organization disciplines by reinterpreting them from oriental perspectives; and to identify mechanisms depicting how they are working together as a whole, which is enabled by exploiting causal loop diagrams as a tool of systems thinking. In addition some thoughts on the implications of systems thinking on each of the learning organization disciplines.

본 연구에서는 창의적 사고력은 협의의 측면으로 정의하여 제시하였고 그리고 비판적 사고력은 강한 의미의 측면으로 정의하여 제시하였으며, 이를 토대로 하여 현행 탐구 교수 전략을 수정 보완하는데 활용할 수 있는 창의적 사고력과 비판적 사고력 신장 모델을 개발하였다. 이 모델은 교사가 물어보는 인과적 질문에 대하여 학생들로 하여금 발산적 사고력을 활용하면서 조별 토론에 의하여 잠정적 설명들을 적어도 세 가지로 응답들을 하게 한 후에, 이어서 조 별 토론하면서 보다 더 나은 하나의 설명(가설)을 선택하도록 하는 가설을 제안하는 과정이다. 발산적인 사고로 다양한 가설들을 만들어 내기 위해서도 조 별 협동학습 활동이 필수적이며, 또한 학생들로 하여금 강한 의미의 비판적 사고를 형성하게 하기 위해서도 반드시 협동 학습에서 조 별 토론에 의하여 얻어진 사고의 결과들을 만들어 내도록 하여야 한다. 이러한 과정을 경험하면서 학생들은 창의적인 사고와 비판적인 수렴적 사고를 작동하게 되는 것이다. 이 창의적 사고력과 비판적 사고력 신장 모델을 적용한 수업 전략에는 기존 수업 전략에 비하여 아주 조그마한 차이만을 보여주나, 이와 같은 창의적 사고력과 비판적 사고력을 활용한 탐구 교수 전략을 중학교 2학년 학생들과 대학교 1학년 학생들에게 적용한 결과에 의하면 비교반과 비교하였을 때 유의미하게 창의력이 신장되었다. 창의적 사고력과 비판적 사고력 신장 모델을 활용한 다양한 여덟 개의 실례들을 개발하였다. 이 여덟 개의 결과들은 기존의 탐구 교수 전략에 들어 있는 인과적 질문에 대하여 설명들(가설들)을 하고 있는 형태들을 갖추고 있다.

This paper investigates psychological differences between constructors and interpreters of causal maps. This paper argues that dissipation effects and dilution effects applies to those who are to interpret causal maps not to those who construct them. Dissipation effects are psychological tendency that people perceive causal effect as weak as the number of causal links increases. Dilution effects occur when people undervalue the strength of causal relation as the number of causal variables increases. Experimental results show that concentration effects opposite to the dissipation effects and dilution effects explain more correctly the perception of constructors of causal maps. This paper points out that this asymmetric psychological tendencies between constructors and interpreters of causal maps is the psychological source of the communication problems between systems thinkers and their clients.

The purpose of this study is to analyze Foreign Exchange(FX) exposure and FX hedge strategy based on the systems thinking perspective using causal loop diagrams. FX exposure has been a critical issue on a business management. Many studies in Korea have researches on variables which make effects to the company value. This study displays causal loop diagrams(CLDs) on these issues. In order to make CLD more objective, most causalities are articulated from recent 72 studies (1998~2013) of domestic top journals. This approach is valuable in that it is the first try to draw all the causalities from various literature review regarding FX exposure and FX hedge strategy. This study is expected to make a useful and basic material to research the financial issues of corporate, as the first research to dynamically understand FX exposure and FX hedge strategy.

The purpose of this paper is to review relationship between spatial characteristics of compact city and urban sustainabiliy from system dynamics perspective using causal loop analysis. It has been argued that spatial characteristics of compact city, high population density and mixed land use, are positively related to urban sustainability. However, research results that are not consistent with pros of compact city argument have been accumulated too. It is especially true when spatial characteristics of compact city are examined with regard to each dimension of sustainablility: economic, social, and environmental sustainability. Reviewing each dimension of sustainability with regard to spatial characteristics based on causal loop analysis, this paper provides more clear understanding on relationship between compact city and sustainability. Also this paper provides a base for system dynamics simulation for future study.

This study aims to conceptually identify the circular causal-relationship which is structured between downsizing and technological innovation in organization. First, through the literature review concerning downsizing and (technological) innovations, we have outlined the conceptual building blocks and research boundaries in this field. Second, we used system thinking method to accomplish our research purpose. The research findings are as follows. First, the promotion of financial resources by downsizing have trade-off relations that have negative of effects in short terms, but positive effects in long time. Second, workforce reduction by downsizing usually has negative influence on employees. Third, capital reduction by downsizing generates not only the climates of cost-cut but also the fact that although the climates may increase economic performance in short terms, it may interrupt technological innovations in long terms. In conclusion, this theses suggests that the relationship of downsizing and technological innovations have complex causal and feedback structures. Therefore, the results of this thesis propose that the argument or practices of downsizing with partial emphasis is very dangerous. Finally some limitations are also discussed.

The defence industry of the Republic of Korea(ROK) has grown up since 1970, however it is facing a growth hindrance due to its structural problem. Many professionals of defense industry has developed some measures to upgrade and energize the defence industry of ROK, and also the current government is implementing various transformations and new policies under the initiative of cooperative independence defence. But most of papers published so far have some limitations resulting from their qualitative contents. And also it is true for them not to show policy alternatives devised by the system thinking. This paper identifies essential factors of defense industry, then analyze the causal relation among those factors. It also shows the causal loop to identify the politic leverages, on which concrete measures to resolve the structural problems are based.

This research aims to identify important variables and their effects on diabetes prevention or progression from prediabetes to diabetic complication using system thinking. Based on the existing studies, we have constructed a causal loop diagram explaining dynamics of diabetes and have found 7 important reinforcing loops and 3 balancing loops in the causal loop diagram. The CLD displays an effect of increasing prediabetes early detection and awareness on diabetes prevention. The findings indicate that the projects in Korea for reducing incidence of diabetes and potential risk of complication have focused on variables which are related only on diabetes even though prediabetes has been a critical point on diabetes prevention and management. Thus, it also concludes that the effect of projects focusing only on diabetes have faced limitation to manage diabetes accordingly.

The purpose of this paper is to explore causal relationship between social capital and firm's performance using systems thinking analysis. In strategic networks, the relationship between the members is an important factor affecting the performance. For this reason, we study relationship between social capital and firm's performance on strategic networks. The results show: Firstly, as presented in the existing research, trust and performance are positive relationship(+) and verify the entire system on strategic networks. Secondly, due to exclusiveness and embeddedness of social capital, there is nonlinear relationship between social capital and the firm's performance. Thirdly, the key factor of firm's performance on strategic networks verify relationship dependency and trust.
