신용평가를 위한 데이터마이닝 분류모형의 통합모형에 관한 연구
김갑식,Kim Kap Sik 한국정보처리학회 2005 정보처리학회논문지D Vol.12 No.2
본 연구는 금융기관에서의 고객신용평가를 위한 최적의 데이터마이닝 모형을 제안한다. 이를 위해 할부금융시장에서의 고객정보 및 할부진행 과정에 대한 세부 내역을 바탕으로 다계층 퍼셉트론(Multi-Layered Perceptrons:MLP)과 다변량 판별분석(Multivariate Discrimination Analysis : MDA), 그리고 의사결정나무(Decision Tree)를 적용하여 각각의 개별모형을 도출하고 이론 유전자 알고리즘을 이용하여 통합한 최종 모형을 구해 그 결과론 각 단일모형과 비교${\cdot}$분석하였다. 그 견과 유전자 알고리즘을 통해 결합한 통합모형의 성능이 가장 우수한 것으로 나타났다. 이에 본 연구는 기존에 진행되었던 개변모형에 대한 검증은 물론, 단순히 여러 개의 모형을 비교${\cdot}$분석하여 우월한 모형을 평가하는 기존 방법론 상의 한계를 극복하기 위해 각각의 개별모형을 유전자 알고리즘을 통해 통합모형으로 구축하는 하나의 방법론을 제시하였다는데 그 의의가 있다. This study presents an integrated data mining model for the credit evaluation of the customers of a capital company. Based on customer information and financing processes in capital market, we derived individual models from multi-layered perceptrons(MLP), multivariate discrimination analysis(MDA), and decision tree. Further, the results from the existing models were compared with the results from the integrated model using genetic algorithm. The integrated model presented by this study turned out to be superior to the existing models. This study contributes not only to verifying the existing individual models but also to overcoming the limitations of the existing approaches.

The evolution of computer has seen the biggest turning point in the history of modern management. With the development of computer and other information technology, firms have been able to manage uncertainty to a certain extent, since decision makers have been able to consider many more contingent variables and obtain more effective and accurate information in more efficient ways. This isespecially true for network technology including VAN, LAN, WAN, MAN in today's more globalized and complicated business environment. Many firms put their efforts to figure out the possibility of increaing effectiveness of decision making and efficiency of daily operations by introducing network technologies. Some firms report successful experiences while the others are not. The level of success mostly determined by if they establish effective ways to utilize various network technoligies or not. This study has been done to propose ways for the effective usage of VAN. (1) The reliability of information from VAN must be fully guaranteed. (2) A VAN should be compatible and integrated with different VANs. (3) A VAN should be able to access and process various information media such as audio information, video information and text information. (4) A satisfactory after-service system is required. (5) Relevant regulations, guidelines and policies should be prepared and implemented effectively. (6) Set up a long-range plans for the training and eduction of VAN experts.

본 논문의 목적은 수령제와 당·정·군 관계를 중심으로 북한 김정은 정권의 권력구조의 특징을 살펴보는 것이다. 본 논문의 문제의식은 북한에서 1967년 유일적 지배체제가 형성된 이후 수령제의 기본 요소인 수령의 유일적 최고결정권, 당적 지배, 정(政)과 군(軍)의 역할 분담 등이 지속되고 있으나, 시대별로 그 기본 요소 간 관계가 재조정된다는 것이다. 김정은 시대 권력구조의 특징은 다음과 같다. 김정은은 김일성\김정일에 비해 수령으로서의 능력이 떨어지기 때문에‘수령 개인의 카리스마에 의존하던 정치’에서‘정치시스템에 의한 정치’로의 전환을 추진하고 있다. 또한 김정일 시대에 약화된 당을 북한정치의 중심으로 이동시키고 있다. 그리고 경제발전과 체제 보위를 위해 내각과 군대의 독자적 역할을 강화하고 있다. 향후 김정은 정권의 권력구조는 김정일 시대의 수령제와 중국의 집단지도체제의 중간형태일 것이다. The purpose of this article is to examine the characteristics of the power structure of Kim Jong-un regime centering on the party-state-military relations in North Korea. This paper is based on the argument that since the official launch of the monolithic leadership system in 1967, the basic elements of suryong system maintained which are: suryong`s monolithic and absolute decision-making power, domination of the party, and continuation of role-sharing between the state and the military. However, these basic elements underwent reconfiguration of relationships by varying periods. The characteristics in Kim Jong-un era are as follows. Compared to his father and grandfather Kim Jong-il and Kim Il-sung, Kim Jong-un has a relatively weaker capability as a suryong or supreme leader. Thus, there are movements to promote transition from ‘politics based on charismatic leadership of the suryong’ to ‘politics based on political system.’ In addition, Kim Jong-un regime is shifting the core of North Korean politics back to the party, which was weakened during Kim Jong-il`s rule. There is also reinforcement of individual roles of the Cabinet and the military to promote economic development and regime security. The future power structure of Kim Jong-un regime is likely to take the middle of the road approach, in between the suryong system in Kim Jong-il era and China`s collective leadership system.

노무현 행정부의 위기관리체계: 인간안보와 재난관리의 접목 가능성
김갑식 ( Kap Sik Kim ) 북한연구학회 2008 北韓硏究學會報 Vol.12 No.2
A distinct feature of contemporary security problem is the emerging role of civil groups. In contrast to the previous traditional meaning of the concept, security, recently, the concept broadens its meaning over the arena of human security which concerns with the improvement on the quality of individual living standards. Civil groups play a leading role in this respect. In addition, as the arena of human security shares lots of issues with the arena of disaster management, civil groups are expected to extend their roles into the crisis management focusing on disaster management. This article, in these respects, aims to explore the features of crisis management system in president Roh administration focusing on the `Crisis Management Manuel` enacted by the National Security Council. In the processes, it claims civil groups should actively participate in the crisis management. In particular, applying the concept of disaster management governance, it examines the possible coordination measures between the governing authority and civil groups about the crisis management.
