강화학습은 환경과 상호작용하는 과정을 통하여 목표를 이루기 위한 전략을 학습하는 방법으로써 에이전트의 학습방법으로 많이 사용한다. 독립적인 에이전트가 아닌 상호 의사소통이 가능한 다중 에이전트 환경에서 에이전트의 학습정보를 서로 검색 및 공유가 가능하다면 환경이 거대하더라도 기존의 강화학습보다 빠르게 학습이 이루어질 것이다. 하지만 아직 다중 에이전트 환경에서 학습 방법에 대한 연구가 미흡하여 학습정보의 검색과 공유에 대해 다양한 방법들이 요구되고 있다. 본 논문에서는 대상 에이전트 학습 정보와 주변 에이전트들의 학습 정보 사이에 편집거리를 비교하여 유사한 에이전트를 찾고 그 에이전트 정보를 강화학습 사전정보로 사용함으로써 학습속도를 향상시킨 ED+Q-Learning 시스템을 제안한다.

In recent years, international cooperation has become important not only at the humanitarian level but also at the socio-economic level. As a result, major foreign countries are increasing capital-intensive international cooperation. In this environment, Korea needs to look for differentiated international cooperation plans centered on sustainable talent cultivation and move away from capital-based international cooperation. In this study, we analyzed the case of HRD (Human Resource Development) center in Cambodia as an international cooperation model between industry-academia-college for training software (SW) workforce. The HRD Center in Cambodia is an educational institution that fosters SW talent and can be viewed as an international cooperation model that can influence the ICT industry in Cambodia as an educational platform. In fact, 190 people who have been hired so far have entered various fields. 97% of graduates have been satisfied with HRD center and 90% of them are willing to recommend the center. In particular, as highlighted in the case study, the HRD Center has had a positive effect on not only cultivating self-initiated learning-based SW talent, but also formulating positive image of Korea and Korean companies thereby facilitating entry into the global market. The HRD Center in Cambodia has developed a virtuous cycle of fostering human resources, providing education, advancing industry and building a cooperative network. Korea has transformed into a platform for international cooperation and human resource development and education by providing active support and aid. This case study will be utilized as a new model of international cooperation with SW expert training platform for Korea.

이 연구는 ‘도로사선제한’(건축법 제60조 3항) 폐지의 배경과 의도를 파악하고 향후 우리 도시에 미칠 영향을 예측하는데 목적이 있다. 이를 위하여 각종 공적 서류의 검토를 통해 넓은 범위에서 개정배경을 분석하였다. 그리고 강남대로 이면도로의 두 건축물을 대상으로 시뮬레이션을 수행하여 개정 이후의 변화 양상을 시각화하여 분석하였다. 공적 서류의 검토 결과, 면밀한 학술적 검토가 부족한 상황에서 정부의 규제개혁을 통한 경제 활성화의 일환으로 추진된 것임을 확인할 수 있었다. 시뮬레이션 결과, 모든 시나리오에서 건물의 연면적 증가가 나타나 투자 촉진 효과가 있는 것으로 나타났다. 하지만 지구단위계획이나 가로구역별 최고높이제한이 적용되지 않는다고 가정했을 때, 무분별한 난개발에 따른 문제점이 발생할 것으로 예측되었다. 따라서 ‘도로사선제한’ 폐지에 이어 지구단위계획구역 및 가로구역별 최고높이제한구역의 지정 확대가 조속히 이루어져야 할 것이다. This study aims to explore the background, purpose, and expected outcomes of the abolition of ‘Diagonal Plane Control by Street Width (DPCSW)’. The methods of this study are as follows: (1) literature reviews with official documents and (2) empirical analysis and simulation with several sites located at a narrow street near Gangnam Station in Seoul. In conclusion, the abolition of DPCSW was intended to promote domestic real estate market, while lacking thorough scientific research. The simulation results show total floor areas in each building would effectively increase with the abolition and boost real estate market. However, the results also indicate without alternative design guidelines, the abolition of DPCSW can result in uncontrolled development with excessive urban density. Alternative urban design regulations such as Building Maximum Height by Block Unit and District Unit Plan should be extendedly applied to a wider area as soon as possible to prevent these issues.
