  • During therapy sessions, feedback is often provided concurrently by the physical therapist as the patient attempts to perform a movement and after the movement attempt. This feedback is provided to enhance the patient's balance abilities. However, recent studies in nondisabled populations have suggested that frequent feedback may be detrimental to retention or learning of motor skills. This study compared the effects of 100% relative frequency of knowledge of performance (KP) with 66% relative frequency of KP for motor learning on balance retraining in patients with hemiplegia. Twenty patients with hemiplegic were randomly assigned to one of two experimental groups. The acquisition phase consisted of 16 blocks of 5 trials for 2 days (80 total practice trials). The retention phase consisted of 2 blocks of a short-term retention test, one day after the end of the acquisition phase and a long-term retention test, one week after the end of the short-term retention test. In the 100% feedback condition, participants received feedback after every practice trial. A faded KP schedule was used in the 66% condition. No significant differences were found between the two groups during all experimental phases (acquisition and retention phases), (p>.05). However, there were significant decreases in balance index for both groups of acquisition phase (p<.05). These results suggest that 66% relative frequency of KP is not more effective than 100% relative frequency of KP with respect to retention over time when hemiparetic patients attempt to learn balance.

  • Knowledge management (KM) is emerging as a robust management mechanism with which an organization can remain highly intelligent and competitive in a turbulent market. Organization knowledge is at the heart of KM success. As a vehicle of acquiring organizational knowledge in a distributed decision-making environment, we applied a fuzzy cognitive map (FMM) technique and proved its effectiveness in a distributed knowledge management environment. Our approach was applied to the financial statement analysis problem, yielding a robust result.

  • Knowledge management has recently emerged as an appealing subject in management literature. Although its history is short, it can benefit greatly from the long history of other related disciplines in building its theories. Innovation, organizational learning, knowledge creation, organizational capability building, technology transfer and network, information technology, organizational behavior, and intellectual capital are the disciplines that have accumulated theories related to knowledge management. This paper first presents a conceptual framework that integrates three dimensions: the characteristics of knowledge (tacit and explicit), knowledge process (acquisition, creation, diffusion, storing, measurement, and application of knowledge), and the unit of analysis (individual, organization, sector, and nation). The conceptual framework produces a number of cells that need to be filled by new theories in order to understand knowledge management better. It then reviews existing theories available in the related disciplines that may be used as building blocks in constructing new theories for these cells. Finally, based on the theories available in other disciplines, the paper suggests a set of future research directions for knowledge management at the level of individual, organization, sector, and nation.

  • Knowledge sharing is safe to say that we have already embarked on knowledge-based global economy where knowledge is a decisive factor in global competition for corporations. So in the age of knowledge-based management, it is how we use knowledge that decides success or failure for corporations and the competitiveness of their countries at large as well. We did this research with the help of those who were working in ICT industry including manufacturing, tourism, and others. In this research, we looked into how project participants, organizational characteristic, and relational characteristic affect knowledge sharing and utilization, and what are the factors that have positive effects on corporate success. And all the factors presented in the research are found to have positive effects on the knowledge sharing and utilization. The factors appeared to have positive effects starting with project at first and then on corporate success at large.

  • 지능형 시스템에서 기존의 수작업 기반의 지식구조 구축은 많은 시간과 노력이 들어가며 환경의 변화에 적절히 적응하기가 어려운 한계가 있다 이러한 한계를 극복하기 위하여 최근 학습을 통한 동적 지식구조 구축방법이 연구되고 있다. 자율 자아 성장(AMD: Autonomous Mental Development)은 자율적 기계 학습의 새로운 패러다임으로 지능형 시스템이 변화하는 환경에 스스로 적응하도록 시도한다 대화형 에이전트에서의 대화 학습은 AMD와 동일한 맥락에서 해석할 수 있다. 본 논문에서는 화행별 템플릿과 유전자 프로그래밍을 이용한 대화형 에이전트의 대화 학습기법을 제안한다. 제안하는 에이전트는 화행별 템플릿을 기반으로 대화 지식을 획득하고 유전자 프로그래밍의 진화 방법을 통해 적절한 표현을 갖는 문장을 생성한다. 적용 사례와 사용자 평가를 통해서 제안하는 방법의 유용성을 확인하였다.

  • 본 연구는 증강현실 활용 역사 독서가 초등학생들의 역사 독서 몰입, 역사 흥미 및 역사 지식 습득에 미치는 영향과 증강현실 활용 독서에 대한 인식을 탐색하였다. 연구를 위해 증강현실 콘텐츠가 포함된 역사책과 증강현실 콘텐츠가 제외된 동일 책을 초등학교 3, 4학년생으로 구성된 실험집단(15명)과 통제집단(15명)에게 제공하였다. 실험 후 역사 독서 몰입, 흥미 및 지식수준에 대한 검사를 실시한 결과 증강현실 활용 독서가 역사 독서 몰입과 역사 흥미 향상에 긍정적인 효과가 있었으나, 역사 지식 습득에서는 유의한 차이가 발견되지 않았다. 또한 학습자들은 증강현실을 통해 공부하는 과정이 즐겁고 재미있다고 인식하였으며, 재미와 흥미를 유발하는 캐릭터, 소리, 현실감 있는 모션, 선명한 3D가 나오는 증강현실 콘텐츠를 선호하였다. 학생들이 선호하는 증강현실 콘텐츠는 재미있는 캐릭터, 긴 동영상과 자막, 그리고 오랫동안 스마트기기를 들지 않고 증강현실 영상을 볼 수 있는 형태 등이었다.

  • Purpose: This study was to evaluate the strengthening process of advanced beginner's nursing competence through the concept mapping methods. Methods: This study was conducted with focus group study for 1 month from November to December 2012 (n=5). Data were analyzed through open coding, axial coding and selection coding stage. Results: Advanced beginner to represent the experience of nursing empowerment and the three categories of the nine concepts were derived. The first category is 'able to see the entire search.' This concept is to start a search query, the search process of thinking, behavior change is expected. The second category is 'behavior change through the acquisition of knowledge.', and this concept is the embodiment of knowledge, confidence rising, and action changing. The third category is 'nursing empowerment', the aesthetic, ethical, and personal knowledge acquisition, as well as self-growth. Conclusion: Advanced beginner saw the full flow through the concept mapping and obtained knowledge, and changed behavior. Thus, the concept mapping is effective to strengthen the nursing competence.

  • Industrial processes are normally operated by skilled humans who have the cumulative and logical information about the system. Fuzzy control has been investigated for many application. Intelligent control approaches based on fuzzy logic have a chance to include human thinking. This paper represents modeling approach based upon operators knowledge without mathematical model of the system and optimize the controller. The experimented system is constructed for sending a ball to the goal position using wind of two DC motors in the predefined path. A vision camera to mimic human eyes detects the ball position. The system used in this experiment could be hardly modeled by mathematical methods and ould not be easily controlled by conventional manners. The controller is designed based on the input-output data and experimental knowledge obtained by trials, and optimized under the predefined performance criterion. And this paper shows the data adaptation for changeable operating condition. When the system is driven in the abnormal condition with unconsidered noise, the new optimal operating parameters could be defined by adjusting membership functions. Thus, this technique could be applied in industrial fields.
