In Western Europo and the US, there has been a general trend over 30 years of reducing the amount of force by the police, through a paradigm shift from 'Escalated Force Model' towards 'Negotiated Management Model'. In tune with this trend, for example, the Swedish Police have implemented the uniformed 'Dialogue Police' system, in order to establish communication contact with demonstrators, before, during, and after their events, The Negotiated Management Model involves a greater respect for the rights of protesters, a more tolerant approach to community, and improved intelligence, communication, and flexibility, in order to facilitate lawful protests and to reduce the possibility of an escalation of major public disorder. The Korean National Police (KNP) appears to be operated within this negotiated management framework, since in preparation for the G20 Seoul Summit, they have also emphasized good communication between the police and protest groups, by newly creating the concept of 'Protest Policing Through Facilitation of Lawful Protests'. In this context, this study first attempts to analyze not only the negotiated management model, but also the Swedish dialogue police. Secondly, the study conducts a comparative study between the KNP's Protest Policing Through Facilitation of Lawful Protest and the Swedish dialogue police system, particularly, in conjunction with the negotiated management. Although Korean and western police have different system and history, protest policing model is now approaching with each other through a link between conflict resolution techniques, such as dialogue, negotiation, mediation and facilitation. Finally, the study is to prove if the KNP's protest policing model corresponds with the negotiated management model, and further to suggest new 'Facilitation of Conflict Resolution Model' as a desirable future of the KNP's protest policing.

An important issue in multiagent reinforcement learning is how an agent should team its optimal policy through trial-and-error interactions in a dynamic environment where there exist other agents able to influence its own performance. Most previous works for multiagent reinforcement teaming tend to apply single-agent reinforcement learning techniques without any extensions or are based upon some unrealistic assumptions even though they build and use explicit models of other agents. In this paper, basic concepts that constitute the common foundation of multiagent reinforcement learning techniques are first formulated, and then, based on these concepts, previous works are compared in terms of characteristics and limitations. After that, a policy model of the opponent agent and a new multiagent reinforcement learning method using this model are introduced. Unlike previous works, the proposed multiagent reinforcement learning method utilize a policy model instead of the Q function model of the opponent agent. Moreover, this learning method can improve learning efficiency by using a simpler one than other richer but time-consuming policy models such as Finite State Machines(FSM) and Markov chains. In this paper. the Cat and Mouse game is introduced as an adversarial multiagent environment. And effectiveness of the proposed multiagent reinforcement learning method is analyzed through experiments using this game as testbed.

This study aims to estimate potential climate change damage in Korea using the PAGE model. This study reviewed previous a reasearch to compare relative sensitivity to climate change in Korea and other regions to generate climate change damage function. It was found that sensitivity to climate change in Korea is similar to other Organization for Economic Cooperation and Development (OECD) countries. This study estimated climate change impact for three scenarios. If no action is taken, climate change damage cost in Korea could reach US$ 12,928 ~ 57,900 M. Cumulative Net Present Value (NPV)of climate change impact from 1990 to 2100 would be between US$ 143,226 ~ 921,701 Mdepending on emission scenarios. However, this result should be interpreted with caution as it draws its damage function based on only a few available references. Results also showed that an adaptation policy could decrease the degree of climate change impact significantly. If an adaptation policy is implemented, climate change impact will be decreased by US$ 11,355 million dollars in Korea in 2100.

지역개발과 지역의 지속가능한 발전전략의 수립을 위해 지역의 환경적, 사회적, 경제적 특성을 통합한 지속가능발전 모델을 구축하는 것은 매우 중요하다. 본 논문은 지속가능발전 전략의 모색과 관련정책의 파급효과를 측정하기 위하여 이러한 통합모델의 개발과 적용을 목적으로 한다. 이러한 목적에 따라 높은 환경질을 유지하고 대나무와 같은 생태자원을 육성함으로써 생태관광과 대나무신산업 등의 새로운 지역개발 정책을 수행하는 전라남도 담양군을 대상으로 지속가능발전 체계동태모형을 구축한다. 담양군 사례분석의 결과는 죽림육성 정책과 대나무신산업과 같은 지역특화산업에 대한 기술개발 및 각종 재원의 병행이 인구유입과 지역경제의 활성화에 매우 효과적임을 제시하고 있다. 결론적으로 본 논문에서는 지역의 지속가능성에 관한 시스템적 사고를 통해 지역개발에 있어서 지역의 환경적 특성을 살린 생태자원의 육성과 적절한 산업정책을 병행하는 생태발전 전략이 지역의 지속가능발전에 있어서 매우 중요한 수단이 될 수 있음을 제시하고 있다.

한국은 세계적으로 정부 주도의 IT 정책이 가장 성공한 나라로 평가되어 왔으나 최근 스마트폰 등 모바일 중심의 세상이 도래하면서 기존 정보통신사업 생태계가 크게 요동치고 있다. 더욱이 이러한 새로운 패러다임 및 BM이 미국발이어서 새로운 시장 창출형 정책선도 모델 발굴이 매우 시급하다. 그러나 과거와는 전혀 다른 새로운 환경, 즉 규제의 힘이 약해지고 새로운 Value Chain 및 산업조직 등 시장의 힘이 강해진 상황에서 이용자의 참여를 유도하고 궁극적으로 시장의 잠재적 수요를 창출할 수 있는 소통적 정책모델 정립이 매우 중요하다고 할 수 있다. 이러한 관점에서 통신산업은 수동적으로 관리해야 할 대상이 아니라 미래 국가경쟁력을 위해서 적극적으로 진흥, 육성해야 할 분야라는 인식전환이 그 어느 때보다 필요하다.

This study examines the most recent successful venture development practices in the United States, Israel, Germany, Finland, and China. The purpose of this study was to find out which foreign country's venture promotion policy is appropriate to korea, why foreign country's venture policy is appropriate to korea and why it is not appropriate, and to draw policy implications for domestic venture promotion and development. The research method was conducted by 50 panel of venture experts using Delphi research technique called 'expert consensus'. As a result of the Delphi research, Finland's venture promotion policy has received the highest evaluation in the usefulness, ease and suitability. Like Finland, the establishment of venture ecosystem through organic activities of private, government, industry, academia, and research was analyzed as the first priority for domestic venture policy. Analyzed. In addition, it was analyzed that the venture policy followed by the private sector under the government's strong promotion policy was no longer appropriate.

본 연구는 다양한 변수에 따라 달라지는 환경산업의 경제성을 비교평가히는 모델을 개발한 것이다. 최근 환경산업으로 부각되고 있는 지역난방과 개별가스난방사업을 사례로 모델을 실증적으로 적용하여 시뮬레이션하였다. 열병합발전과 보조보일러 및 쓰레기 소각로로 구성된 지역난방시스템과 소각로와 개별 가스보일러로 구성된 개별난방시스템을 각각 최적화하고 최저비용을 구하여 비교한 것이다. 분석대상에 쓰레기소각로을 첨가함으로써 매립에서 소각으로 바뀌는 쓰레기정책을 반영하였으나 소각로 규모는 사전에 열공급과는 무관하게 결정되므로 다른 시스템과 연계하여 최적화 하지 않고 600톤/일의 규모로 정하여 분석하였다. 최적화하는 경우는 훨씬 규모가 줄어드는 것으로 나타났다. 국가경제적인 측면에서 다양한 난방방식에 따른 규모별, 열원별, 지역별(기후별), 사용연료별로 경제성과 환경성을 비교평가함으로써 변수의 변화에 따른 합리적인 난방방식 및 사용연료를 선택하도록 하였다. 환경배출량도 동시에 비교하였으나 시나리오 간에 크게 차이가 나지않아 비교에는 포함시키지 않았다. 이 모델은 난방사업 뿐만 아니라 갈등이 예상되는 다른 환경산업들을 평가하는데도 용이하게 활용될 수 있도록 GAUSS프로그램으로 개발되어 있다.

Recently, housing prices have surged, and the government has implemented various regulations, such as finance and taxes. Because of the policy, the nationwide housing price have stabilized, but polarization has occurred. Some argue that regulation can adversely affect the actual demand. Therefore, not only the correlation between market variables but also ripple effect of policy has to be analyzed in policy planning and analysis from a microscopic point of view. In this study, a simulation model was developed by integrating system dynamics for analyzing market structure and agent-based model for modeling decision process of market participants. This research applied the financial regulation and the tax regulation to the model and evaluated the policy effectiveness. This study reveals which feedback dominates according to the policies, which have same purpose. It is because market participants make different decision for each policy. Furthermore, there were other ripple effects not only in the policy target submarket but also in other submarket.

This research investigates the quantitative screening methods for the Grant Funding system and seeks for the efficient evaluation of a number of proposals. We search foreign cases of Grand Funding, but we found no appropriate model for using in Korea. Thus, we had to develope our own model for better screening. First, we analyse the existing evaluation system and find some problems and challenges. Second, we suggest a quantitative screening system for Grant Funding with a numeric model, and operates a tedious simulation by using the previous data and our suggested model. Third, we test the suggested model and find the optimal model by using simulation method The number of data analysed for simulation is larger than 200 thousands. Last, we suggest some brief policy implications based on the results in the paper.
