  • The current business environment has been characterized as less munificent, highly uncertain and constantly evolving. In this environment, the company with dynamic capability is reported to be more successful than others in building competitive advantage. Dynamic capability focuses on the link between a dynamically changing environment, strategic agility, architectural reconfiguration, and value creation. Being characterized to be flexible and adaptive to market circumstance changes, an organization with dynamic capability is described to have high resource fluidity, which represents business process, resource allocation, human resource management and incentives that make business transformation faster and easier. Successful redeployment of the resources for dynamic adaptation requires organizational forms and reward systems to be well aligned with firm's technological infrastructures and business process. The alignment is considered to be an executive level commitment. Building dynamic capability is knowledge driven; relying on new knowledge to reconfigure firm's resources. Past studies established the link between the effective execution of a knowledge-focused strategy and relevant setting of architectural elements such as human resources, structure, process and information systems. They do not, however, describe in detail the underlying processes by which architectural elements are adjusted in coordinated manners to build knowledge-driven dynamic capability. In fact, understandings of these processes are one of the top issues in IT management. This study analyzed how a Korean corporation with a knowledge-focused strategy aligned its architectural elements to develop the dynamic capability and thus create value in the dynamically changing markets. When the Korean economy was in crisis, the company implemented a knowledge-focused strategy, restructured the organization's architecture by which human and knowledge resources are identified, structured, integrated and coordinated to identify and seize market opportunity. Specifically, the following architectural elements were reconfigured: human resource, decision rights, reward and evaluation systems, process, and IT infrastructure. As indicated by sales growth, the reconfiguration helped the company create value under an extremely turbulent environment. According to Ancona et al. (2001), depending on the types of lenses the organization uses, different types of architecture will emerge. For example, if an organization uses political lenses focusing on power, influence, and conflict. the architecture that leverage power and negotiate across multiple interest groups would emerge. Similarly, if an organization uses economic lenses focusing on the rational behavior of organizational actors making choices based on the costs and benefits of action, organizational architecture should be designed to motivate and provide incentives for the actors (Smith, 2001). Compared to this view, information processing perspectives consider architecture to be designed to maximize the capacity of information processing by the actors. Using knowledge lenses, the company studied in this research established architectural elements in a manner that allows the firm to effectively structure knowledge resources to form dynamic capability. This study is revelatory single case with a historic perspective. As a result of this study, a set of propositions and a framework are derived, which can be used for architectural alignment.

  • By providing a number of unprecedented knowledge sources, virtual communities have stimulated interests in knowledge sourcing Specifically, virtual communities have triggered fundamental changes in the ways that people interact with one another. Thus, there is a critical need to examine how people try to behave for sourcing knowledge in virtual communities, particularly in terms of the demand-side perspective of knowledge. To address the knowledge gap regarding knowledge sourcing behavior from the knowledge recipients' side, this study draws upon GPA(goal-plan-action) theory with both the social cognitive theory and the goal-setting theory as overarching theories. Furthermore, we apply past experience in virtual communities and trust in knowledge providers as moderating variables to deeply understand the knowledge recipients' behavior. We expect to present theoretical and practical implications through our findings, which are relevant to cognitive goal-setting and knowledge sourcing behavior. In the theoretical perspective, this study illustrates how knowledge recipients determine knowledge sourcing behavior. Based on our findings, this study has practical implications for virtual communities to effectively balance knowledge repositories and knowledge management systems with knowledge providers and recipients.

  • 금융기관의 지식경영 초기 단계 이후부터는 지속적인 지식 창출과 효율적인 지식 검색이 지식경영의 핵심 요인으로 보고, 지식 창출의 한 방안으로 e-러닝을 제시하고, 효율적인 지식 검색 체제를 구축하기 위해서 리포지토리에 저장된 학습객체, 지식객체, 자료실 정보객체를 유사성에 따라 분류하고 상호 연관관계를 맺음으로써 키워드 검색은 물론 분류 검색과 연관 검색을 가능하게 하는 토픽맵 개념에 기반을 둔 지식맵을 활용한 통합 리포지토리 모형을 제안해 보았다. 모형 구현을 위해서 사용된 연구 방법에는 지식 관리 현황을 파악하기 위해서 세 보험회사들을 대상으로 사례 연구를 실시하였고, 기존의 토픽맵 기반의 실험적인 정보시스템들도 분석, 참조하였다. 디렉토리 형식의 전통적인 지식맵은 관련된 지식을 연계시키기가 어려워 지식관리시스템의 효율적인 브라우징이나 검색에 걸림돌로 작용하고 있는데 본 연구에서 제안된 모형은 이러한 문제점들을 개선할 하나의 안으로 이용될 수 있을 것이다.

  • The wide spread of internet business recently necessitates recommendation systems which can recommend the most suitable product fur customer demands. Currently the recommendation systems use content-based filtering and/or collaborative filtering methods, which are unable both to explain the reason for the recommendation and to reflect constantly changing requirements of the users. These methods guarantee good efficiency only if there is a lot of information about users. This paper proposes an algorithm called 'demand articulate & integration' which can perceive user's continuously varying intents and recommend proper contents. A method of knowledge classification which can be applicable to this algorithm is also developed in order to disassemble knowledge into basic units and articulate indices. The algorithm provides recommendation outputs that are close to expert's opinion through the tracing of articulate index. As a case study, a knowledge base for heritage information is constructed with the expert guide's knowledge. An intelligent recommendation system that can guide heritage tour as good as the expert guider is developed.

  • 위성의 수와 복잡도가 증가함에 따라서 다양한 고장이 생기는 경우를 예측하고 고장이 발생한 경우 이를 감지하여 신속히 감지하여 처리하는 노력의 필요성이 증가하게 된다. 현재는 위성 관제소의 전문요원들이 이러한 작업을 수행하고 있지만, 많은 부분이 일상적인 작업이므로 이러한 진단 작업을 자동화할 필요성이 있다. 즉, 일상적인 작업은 전문가시스템이 수행하고, 보다 복잡하고 고차원적인 문제는 전문요원이 해결하는 방식이 바람직하다. 이 논문에서는 이러한 노력의 일환으로 인공지능의 사례기반 방식을 도입한 위성 고장진단 전문가시스템을 구축하기 위한 방법론과 이에 따른 프로토타입 시스템을 설계하고 구현하였다. 사례기반 시스템은 과거의 사례를 기억하고 있는 사례베이스를 구축하고 고장의 증상이 발생한 경우에 이러한 사례베이스로부터 가장 근사한 경우를 인덱스하여 처리하는 기능을 가지고 있다. 이 논문은 이러한 기능을 가지는 사례기반 시스템의 구조와 활용방안에 대해서 서술하고자 한다.

  • Fuzzy control has been researched for application of industrial processes which have no accurate mathematical model and could not controlled by conventional methods because of a lack of quantitative input-output data. Intelligent control approach based on fuzzy logic could directly reflex human thinking and natural language to controller comparing with conventional methods. In this paper, the tested system is constructed for sending a ball to the goal position using wind from two DC motors in the path. This system contains non-linearity and uncertainty because of the characteristic of aerodynamics inside the path. The system used in this experiment could be hardly modeled by mathematic methods and could not be easily controlled by linear control manners. The controller, in this paper could control the system containing non-linearity and uncertainty because it is designed based on the input-output data and experimental knowledge obtained by trials.

  • A behavior-based control and learning architecture is proposed, where reinforcement learning is applied to learn proper associations between stimulus and response by using two types of memory called as short Term Memory and Long Term Memory. In particular, to solve delayed-reward problem, a knowledge-propagation (KP) method is proposed, where well-designed or well-trained S-R(stimulus-response) associations for low-level sensors are utilized to learn new S-R associations for high-level sensors, in case that those S-R associations require the same objective such as obstacle avoidance. To show the validity of our proposed KP method, comparative experiments are performed for the cases that (ⅰ) only a delayed reward is used, (ⅱ) some of S-R pairs are preprogrammed, (ⅲ) immediate reward is possible, and (ⅳ) the proposed KP method is applied.

  • In manufacturing process, usually 2-dimensional part drawing is used as a basic data. If a designer wants to recognize 2-dimensional drawing and formulate 3-dimensional shape, a proper feature recognition rule is required as a prerequisite step. These rules are converted Into knowledge base, should be ed separately in the recognition program and can be referenced In similar way of database application. In this paper, basic feature recognition rules are addressed in structure type knowledge base, and the application system is formulated which can be operated separately with existing data driven program.
