South Korea has been reluctant to open its geospatial information overseas to ensure security as a divided country. However, this cannot continue as the domestic and international environments related to geospatial information and the industrial ecosystem of information and communication technologies have been changing dramatically. Within this context, this study aims to analyze the causal relations among relevant variables and how they change and interact with time using a systems thinking process. First, causal maps were created for the domains of national security, map-based convergence service, and corporate competition. Then, the causal maps for each domain were integrated, based on which the points for policy intervention and dominant feedback loops were identified. The analysis results showed that securing the self-sufficiency of domestic geospatial businesses is a key element to determine the whole causal map, and the variable that changes the dominant feedback loop from a vicious circle to a virtuous one is the decision to open geospatial information overseas. In this study, I found the policy leverage that is a policy intervention point that can produce a great effect with little input by building a causal map of the interactions between major variables. This study is significant in that it identified and analyzed the dominant feedback loop as to which causal structure would dominate the system in the long term. The results of this study can be used to discuss not only the impacts of map data overseas opening on the national security and geospatial information industry, but also the interactions in the future when Google or other global companies request to release the geospatial information.

Up until now, Korea has been recognized as one of the most severe and strict countries in terms of social regulation. As a result of that, it is generally accepted that economic activities in private sector have been contracted to some extent, weakening national competitiveness. Under this background, this paper examines the complex relationships among factors affecting national competitiveness and regulation and also seeks to discover feedback loops associated with its relationship. The research result shows that reinforcing feedback and balancing feedback loops are found in the system concerned with national competitiveness and regulation. Accordingly, it implies that we need to pay our attention to the management of those loops in order to discover the optimal point striking the balance between regulation and deregulation in terms of national competitiveness. It also implies that we need to conduct sensitivity analysis to forecast the potential results which the scenarios will bring about.

이 논문은 현재 해양오염관리의 패러다임을 분석하고 시스템 과학화에도 불구하고 드러난 초동대응 실패, 대응체계혼선, 피해 최소화 실패 등 문제점과 이를 통한 변화의 전조와 인과관계를 동시에 고려할 수 있도록 인과지도(Causal Map)를 작성하여 변화를 분석했다. 현재 패러다임의 지배적 피드백 루프(Dominant Feedback Loop)를 파악하고 이를 통해 유출원을 신속하게 봉쇄할 수 있는 장비 개발과 더불어 피해자로만 인정하는 지역주민에 대하여 방제활동 및 전략수립을 결정하는 자원으로 전환시킬 수 있도록 프로그램 개발과 더불어 지원, 협조되는 기관의 증가에도 현장에서 신속하게 판단할 수 있는 체계로 개선되어야 한다.

If a system such as a port and regional economy has a large boundary and complexity, the system's substance is considered as a black box, forecast accuracy will be very low. Futhermore various components in a port and regional economy exert significant influence on each other. To copy with these problem the form of structure models were introduced by using SD model. This study has the issue of simplifying the regional economic effects of the port as contributing to raising the regional income. The regional economic effects of port have various indirect ones except for this. So, SD(System Dynamics) was presented, and applied to simulate port and regional economy.

The number of professionals in the science and engineering fields decreases all over the world. Especially in Korea, the declining rate of both the laborable and economically active population, aging of the population at the fastest level, and the declining birth rate make it tougher to secure the core brains of the future. After speculation of all programs above, some common factors have been derived and every program appeared to have the support for each level of inducing, caring, and utilizing. And the means of support could be categorized into the financial, legal, and social aspects. Lastly, a logical tool called Systems Thinking has been applied to the FLS Conditions and the Brain Internalization Process to assure the efficacy and applicability of the models. This is to minimize any de facto side effects by analyzing all 'feedback loops' stemming from the models. And the 'causal loop diagrams' have been utilized to come with the complementary measures. Such series of verification could convince the virtue of the models. Governments and universities can make use of the FLS Conditions and the Brain Internalization Process so the policies or plans about the foreign brains can be built in a uniformized and consistent framework. I hope, as a result, the international competency of Korea to induce and utilize the foreign brains be raised with the constant and standardized formality.

우리나라에서 원자력 시설의 안전 확보를 위한 현장 규제는 원전 부지내에 설치되어 운용되고 있는 주재관실과 방사능 재난 발생에 대응하기 위한 현장방사능방재지휘센터 등으로 분산되어 있다. 원유 고유가, 에너지 안보, 및 기후 변화 협약 등에 대한 대응책으로, 신규 원자력 시설의 건설이 진행 중에 있으며, 이에 따라 원자력 규제 대상이 증가하고 있다. 지역주민이 신뢰하는 원자력 시설의 안전 규제의 필요성에 따라 현장 규제의 업무량도 증가하고 현장 규제 요건도 강화되고 있는 추세이다. 분산되어 있는 원자력 안전규제 시스템을 통합적인 체계로 전환하기 위한 방안들 가운데, 이 연구에서는 규제의 효율성/효과성을 향상시키기 위해 원자력 안전 지역사무소의 설치가 고려되었다. 이 연구의 주요 목적은 시스템 다이내믹스 기법을 활용한 지역사무소 설치의 타당성 모델을 제시하는 것이다. 이 SD 모델을 통해 지역사무소 설치가 규제 효과성을 포함한 다른 변수들에 미치는 영향을 전체론적 (holistic) 관점에서 평가할 수 있다. 이 SD 모델에서 이해관계자 (예: 중앙행정기관, 규제기관, 지방자지단체, NGO, 국민 등) 각각의 우선적인 목표는 갈등적 다중목표가 된다. 이러한 다중목표는 원자력 안전 규제의 의사결정 단계에서 거버넌스(governance) 체제 (예: 규제 기관, 사업자, 지역주민 등이 참여하는 체제)의 구축, 원자력 관련 민원 해결을 통해 성취될 수 있다. 시스템 다이내믹스 접근법의 주요 변수 정의 단계에서는 다양한 관점의 상호영향을 고려하면서 지역사무소 설치에 필요한 기본 개념이 도출되었다. 시스템 다이내믹스 접근법의 모델링 단계에서는 이들 기본 개념에서부터 지역사무소 설치 타당성 정책의 인과 지도(causal map)가 작성되었다. 이러한 인과 지도들로부터 지역사무소의 설치 타당성으로 이끄는 다양한 자기-강화 (self-reinforcing) 루프들이 발견되었다.

The purpose of the study is to research students' proficiency with systems-thinking approach concerning water cycles and to acquire data on Earth System-related concepts based on students' feedback. To achieve the purpose of the study, I chose 4 mid-level high school juniors living in Pohang, where the high school equalization policy has not been implemented, and the students answered a questionnaire about water cycles. Then, based on the results, I created a causal map and evaluated it using systems-thinking analysis. The results of the study are as follows: First of all, among the answers of the subjects, there were 21 concepts related to the conception of the earth system : 14 of the conceptions were linked scientifically, and 7 of the conceptions were not linked scientifically. Secondly, results of the causal map of what the subjects described showed that only two students'(A and C) feedback loops were completed, and that student C's feedback loop included unscientific reasoning. In conclusion, this study indicated that the students failed to understand the water cycle with the systems-thinking approach, or alternatively they applied low-level systems-thinking approach and had a lower understanding of it.

Ship is bring operated under a highly dynamic environments and many factors are related whit marine accident and those factors are interacting. An analysis on the marine accident is very important to prepare countermeasures which will ensure the safe navigation. This paper aims to build a model of the causes and improved policy for marine accident using SD(System Dynamics} approach and to measure a effect which is risk control countermeasures of marine accident. The methodology of this paper is to perform the causes and improved policy for marine accident using Brainstorming method and was to changed by quantitutive, qualitative factors and their feedback loops in casual map. This model was performed over 23 years($1997\~2020$) in a standard simulation model and 4 policy simulation models.

본 연구에서는 시스템다이내믹스(System Dynamics, SD) 방법론에 입각하여 국내의 신기술인증제도(New Technology Certification System, NTCS)의 운영에 내재된 요소들 간의 상호관계를 신기술 개발투자, 신기술의 사업화 및 신기술에 의한 매출과 연관하여 피드백루프 메카니즘을 내포하고 있는 인과지도로 규명하였다. 이렇게 개념화된 인과지도는 국내의 여러 신기술인증제도 중 환경부에서 운영중인 '환경신기술인증 및 기술검증제도(New Excellent Technology and Environmental Technology Verification, NET & ETV)'에 적용되었으며 NET & ETV의 운영 성과를 신기술에 의한 매출액(수주금액)의 관점에서 분석 및 예측할 수 있는 SD 컴퓨터 시뮬레이션 모델이 개발되었다. 개발된 SD 모형은 NET & ETV 운영의 주요 지표에 관한 기존 통계자료를 적절히 모사하였으며 모형의 검증과정에서 시행착오를 통하여 산정된 값들은 NET & ETV의 일반적인 과거 상태를 합리적인 범위 내에서 적절하게 나타내고 있는 것으로 나타났다. 본 연구에서는 개발된 SD모형을 이용하여 기본시나리오에 대한 NET & ETV의 미래 운영 상태를 예측하였으며, 환경신기술의 적용 현장 당 수주금액에 대한 시간 추세선식의 민감도를 발견하였다.
