The purpose of this study is to identify the procedures leading to gambling addiction and its implications. To achieve this goal, a causal map and System Dynamics (SD) simulation model of gambling addiction were constructed firstly. Second, the implications for the current gambling addiction policies were derived using the results of causal map and SD simulation analysis.
The implications could be summarized as follows. Primarily, the current policy for developing legal gambling should be changed to policy to control the total amount of gambling and to research on the prevention of gambling addiction. Next, efforts should be made to apply the anti-addiction measures created through the research to the illegal gambling industry.

In the information age, where convergence of all information and devices has become a reality, standards have increased in importance as strategic assets. The purpose of this research is to understand the dynamic mechanisms surrounding standards. To this end, this paper examines the theoretical discussions related to standards and constructs a causal map on the dynamic mechanism of standardization. Through this analysis, this paper proposes the dynamic mechanism of standardization. This paper also attempts to point out the positive effects of standards led by the government as well as negative effects.

Efforts to promote ecotourism at major ecotourism sites in Korea remain at the macroeconomic policy stage, such as maximizing the value of ecosystem services or expanding protected areas, without considering the degradation of the biological habitat environment due to increased visitor pressure and tourism infrastructure. In addition, the development of underdeveloped areas and infrastructure for the vitalization of the local economy is given priority, and ecotourism is stagnant due to the conflict between natural environment conservation and social environment development. Therefore, a research is needed to understand the current situation of ecotourism and to suggest solutions. In this study, literature review on ecotourism impacts and social-ecological systems were carried out, and the Nakdong Estuary ecotourism system was analyzed. In addition, this paper suggests a transformation plan of tourism resources. This study has the scalability that can be applied to check the current system and suggest improvement methods in various ecotourism sites.

After The Limits to Growth, System Dynamics studies, alike C-Roads, have been following a strong tradition of the prediction which was considered as a function of System Dynamics. And until now, this has been focused mainly on Stock-Flow Diagram.
However, this study suggests a new way of the future prediction through the future analysis based on Causal Loop Diagram, as following the System Dynamics philosophy.
This future analysis is different with Future Study. In this paper we discuss the concept of causality, time, future prediction, which are the philosophycal ground for future analysis with Causal Loop Diagram.
Moreover, this study suggests an expanded way to describe the predicted future with a combined methodology of Casual Loop Diagram and the scenario method. Using this way, without computational simulation, the future analysis could address the predicted future within the system dynamics philosophy.
