In a new era of Cloud and Big data, how to search the useful data from dynamic huge data pool in a right time and right way is most important at the stage where the information is getting more important. Above all, in the era of s Big Data it is required to design the advanced efficient intelligent Knowledge system which can process the dynamic variable big data. Accordingly in this paper we propose Dynamic personal Knowledge Network as one of the advanced Intelligent system approach. Adopting the human brain function and its neuro dynamics, an Intelligent system which has a structural flexibility was designed. For Structure-Function association, a personal Knowledge Network is made to be structured and to have reorganizing function as connecting the common nodes. We also design this system to have a reasoning process in the extracted optimal paths from the Knowledge Network.

Fuzzy Cognitive Map (FCM) and Bayesian Belief Network (BBN) are two major frameworks for modeling, representing and reasoning about causal knowledge. Despite their extensive use in causal knowledge engineering, there is no reported work which compares their respective roles. This paper aims to fill the gap by providing a qualitative comparison of the two frameworks through a systematic analysis based on some inherent features of the frameworks. We proposed a set of comparison criteria which covers the entire process of causal knowledge engineering, including modeling, representation, and reasoning. These criteria are usability, expressiveness, reasoning capability, formality, and soundness. The results of comparison have revealed some important facts about the characteristics of FCM and BBN, which will help to determine how FCM and BBN should be used, with respect to each other, in causal knowledge engineering.

The purpose of this study is to look into the influence of salesperson's human networking and knowledge on its job in an insurance company in its performances and to suggest how to effectively manage and develop salespersons. For this study, 305 salespersons participated in a questionnaire survey and we used T-TEST to analyze the data. The results are as follows. Its performance is positively influenced by salesperson's networking and knowledge on its job. In term of moderating effect on the attitude for its job, making efforts to organize networking was rejected, however the attitude for retaining their networking positively affected to the performance. As a result, the higher the level of salesperson's knowledge and networking is the higher its performance. To increase competitiveness, an insurance company has a strategy for the support to organize networking and the training of salespersons to become high performers.

기업 네트워크에서 안전하고 효과적이며 안정된 망 운영관리 환경 제공은 당면한 중요과제이며 기업 경쟁력의 핵심인 정보기술을 통한 생산성과도 연계성을 갖고 있다. 이러한 필요에 맞추어 많은 네트워크 관리 시스템들이 개발되어 상용화 되었으나 이들 관리시스템들은 트래픽 모니터링에 의한 통계값 제공과 같은 단순 평면적인 관리 기능만을 제공할 뿐 네트워크의 특성과 환경에 따른 분석, 진단 기능은 제공하지 못하고 있다. 또한 현재의 네트워크 환경은 다양한 통신장비와 서비스들의 개발에 따른 망 구성 요소의 이질성과 복잡성이 증가하고 있으며 이는 전문적인 네트워크 운영관리와 분석기술을 요구하고 있다. 이는 관리자에게 네트워크가 점점 다양화, 복잡화 되는 환경에서 부담으로 작용할 뿐 아니라 결과를 도출하는데 많은 시간과 비용이 소요된다. 따라서 기존 네트워크 관리 시스템의 한계를 극복하고 네트워크 환경 변화를 수용, 관리자의 운영경험지식을 데이터베이스화하여 지능적인 네트워크의 분석과 진단이 가능한 시스템의 개발이 필요하다. 본 논문은 이러한 시스템 구축의 전제조건으로 네트워크 운영경험 데이터베이스를 구축하여 이를 통한 네트워크 환경 변화를 수용할 수 있는 임계값 최적화와 향후 한국전력 사내 데이터통신망의 지능화된 분석과 진단을 위해 활용하게 될 지식 발견 시스템을 설계 및 구현하였다.

최근 몇 년 동안 웹 기반의 서비스는 웹 2.0이라는 단어로 설명되면서 집단지성, 소셜네트 워크서비스 등 다양한 형태로 발전되어 왔다. 특히 소셜네트워크서비스는 모바일 환경의 발전과 함께 수년간 계속 발전할 것으로 예상된다. 그리고 집단지성의 경우 이제는 웹기반 서비스에서 고객의 요구를 판별하고, 새로운 지식을 작성하는 방법으로 많이 활용되고 있다. 본 논문에서는 인공지능의 한 방법인 전문가시스템(Expert System)과 집단지성의 기술을 활용하여 전문지식을 관리하는 소셜네트워크서비스의 설계 및 구현의 과정을 설명하고자 한다.

신경회로망 구조의 정제(精製)는 회로망의 일반화능력이나 효율성의 관점에서 중요한 문제이다. 본 논문에서는 feed-forward neural networks로부터 은닉지식을 추출하는 방법을 사용하여 네트워크 재구성을 통한 정제방법을 제안한다. 먼저, 효율적인 if-then rule 추출방법을 제시하고 그 추출된 룰들을 사용하여 룰기반 네트워크로 변환하는 과정을 보여준다. 생성된 룰기반 네트워크 fully connected network에 비하여 상당히 축소된 연결 복잡도를 가지게 되며 일반적으로 더 우수한 일반화능력을 가지게 된다. 본 연구는 도메인 지식이 없이 데이타만 사용하여 어떻게 정제된 룰기반 신경망회로를 생성하고 있는가를 보여준다. 도메인 데이타들에 대한 실험결과도 제시하였다.

The study sets out to examine the relationship between the effects of government support, network capability, and knowledge sharing on the effects of innovative behavior on innovation performance. As digital-based networks and knowledge sharing activities are rapidly becoming common in the era of the spread of Covid-19, 357 questionnaires were analyzed for incumbent employees and the research hypotheses are verified using SPSS 24 and smart PLS 3 to prove the relationships between variables. As a result of the study, it is found that innovation performance increased when government support, network capability, and knowledge sharing increased. Innovative behavior is found to significantly mediate the relationship between network capability, knowledge sharing, and innovation performance, and government support was found to have a significant effect on network capabiltiy. Therefore, in order to induce innovative actions that are important in creating innovative results, various programs to enhance the network capabilities of entrepreneurs and promote knowledge sharing should be required as government support policies. This will serve as a driving force for entrepreneurs to voluntarily develop and implement ideas more flexibly and freely, thereby enhancing competitiveness through innovative growth of companies and industries. In other words, this study verified the effectiveness of government support in the network capability to help create innovative results by inducing innovative behavior along with knowledge sharing activities, and comprehensively demonstrated the relationship between factors in the overall structure.

The use of social media has many advantages such as knowledge sharing, social networking, and communicating with other people. However, it has given rise to various side effects including stress, Which is defined as social network stress in this study. This study aims to conceptualize social network stress and investigate its effect on switching behavior in social media. For this purpose, we present a research model that consists of the antecedents and consequences of social network stress and test it empirically using LISREL 8.7 based on the structural equation model. The empirical results showed that knowledge sharing and self-disclosure had positive impact on social network stress, which in turn positively influenced social media switching behaviors. In conclusion, we discussed both theoretical and practical implications of this research and suggested its limitations.
