  • 저장 및 관리하는 지식의 분류체계로서의 의미를 갖는 지식지도는, 문제해결을 위하여 지식을 조회 및 선택하는 사용자의 활동을 지원하고 보완할 수 있는 구조를 갖추어야 한다. 계층형 구조를 갖는 기존의 지식지도는, 관리하는 지식을 체계적으로 정리하는 데에는 이점이 있으나, 지식 사용자가 갖는 인지 및 활용의 논리를 반영하지 못할 뿐만 아니라 지식을 조회 및 추출하는 사용자의 활동을 지원하지 못한다. 본 연구는, 내용적 관련성을 갖는 연관지식을 연쇄적으로 조회 및 추출하는 사용자의 지식활용 패턴을 반영하는, 키워드 기반 네트워크형 지식지도를 구축하는 방법론을 제시한다. 즉, 지식 간 내용적 연관성을 파악하기 위하여 키워드를 추출하고 공통된 키워드를 갖는 지식 간 링크를 해당 키워드를 이용하여 정의한다. 키워드는 해당 지식의 내용을 대변하므로, 키워드를 기반으로 정의된 링크는 내용적으로 관련성이 있는 지식 간에 형성되며, 이를 종합하면 내용적 연관성을 지식 간의 네트워크, 즉 네트워크형 지식지도가 완성된다. 제시된 방법론의 적용 타당성을 검토하기 위해 50개의 연구논문을 이용하여 이들 간의 내용적 연관성을 표현하는 네트워크형 지식지도를 구현하였으며, 검토 결과 만족할만한 수준의 정밀도와 재현율을 보였다.

  • Knowledge is important to both individuals and organizations. Individuals can have the opportunity to have bargaining power within their organisations by having knowledge of know-how and ideas. Having ample knowledge of the organization can bring about advantages in securing competitive advantage. Organization wants to encourage employees to share knowledge. Despite the efforts to enhance knowledge sharing, often the effort failed. Employees are unwilling to share their knowledge or hide their knowledge. The purpose of this study is to clarify the relationship between knowledge hiding and knowledge sharing based on exploring the influence factors of knowledge hiding and knowledge sharing. As a result, the influence factors of knowledge hiding and knowledge sharing were different. The influences of knowledge hiding influenced knowledge hiding only and did not affect knowledge sharing. This implies that knowledge hiding and knowledge sharing do not exist on a single line but exist independently of each other, such as 'Herzberg's two-factor theory'. This study suggests that knowledge hiding is a field of interest as well as knowledge sharing. In practice, it is suggested that the concept of promoting knowledge sharing is not a way to reduce knowledge hiding, so the two concepts should be managed separately.

  • The definition of convergence employed in this study is a sociocultural phenomenon where different patterns, genres or fields coexist along with the existence of a knowledge based society. The focus of this study was centered on identifying the characteristics of contemporary fashion paradigm in association with changing cultural convergence according to the theories of Mark Weiser and other futurologists. The purpose of this study was to delve into the features of this paradigm in conjunction with changing cultural convergence in 21st century's knowledge-based society, and the influence of convergence paradigm on fashion. After identifying the features of knowledge-based society paradigm in association with changing cultural convergence, the characteristics of the fashion paradigm in order to ascertain and analyze fashion trends. Conclusions based on analyzed data indicate that in a knowledge-based society, paradigm change resulting from convergence phenomena contributes to facilitating the dissolution of fashion from other fields and its fusion with other areas.

  • This study proposes a dependency grammar-based self-attention multilayered bidirectional long short-term memory (DG-M-Bi-LSTM) model for subject-predicate-object (SPO) tuple recognition from natural language (NL) sentences. To add recent knowledge to the knowledge base autonomously, it is essential to extract knowledge from numerous NL data. Therefore, this study proposes a high-accuracy SPO tuple recognition model that requires a small amount of learning data to extract knowledge from NL sentences. The accuracy of SPO tuple recognition using DG-M-Bi-LSTM is compared with that using NL-based self-attention multilayered bidirectional LSTM, DG-based bidirectional encoder representations from transformers (BERT), and NL-based BERT to evaluate its effectiveness. The DG-M-Bi-LSTM model achieves the best results in terms of recognition accuracy for extracting SPO tuples from NL sentences even if it has fewer deep neural network (DNN) parameters than BERT. In particular, its accuracy is better than that of BERT when the learning data are limited. Additionally, its pretrained DNN parameters can be applied to other domains because it learns the structural relations in NL sentences.

  • Knowledge1 is considered to be a key element of understanding how organizations gain and sustain competitive advantages. But very few firms are capable of creating the requisite knowledge and thus, firms should acquire and exploit new knowledge through knowledge transfer processes. The empirical part of this study involves examining relationships among adaptability of knowledge and knowledge transfer and marketing performance and testing the moderating roles of absorptive capacity, socialization and local marketing knowledge. This study is organized as follows: (1) Previous literature on knowledge, knowledge transfer and absorptive capacity is summarized, followed by the development of hypotheses derived from the knowledge-based view and absorptive capacity. (2) The hypotheses are tested with data collected from MNCs' subsidiaries performing marketing activities in Korea.Thestudyisclosedwithfindings,implications,andconclusions. Following six research hypotheses are drawn from literature review in related areas: H1: Adaptability of knowledge transferred from the MNCs' headquarters and other subsidiaries is positively associated with knowledge inflows into the receiving subsidiary. H2: The level of marketing knowledge transferred from the MNCs' headquarters and other subsidiaries is positively associated with marketing performance of the receiving subsidiary. H3: Increases in potential absorptive capacity will enhance the relationship between adaptability of knowledge and the level of marketing knowledge transfer. H4: Increases in realized absorptive capacity will enhance the relationship between the level of knowledge transfer and marketing performance of the receiving subsidiary. H5: Increases in socialization activity among the headquarters and subsidiaries will enhance the relationship between adaptability of knowledge and the level of marketing knowledge transfer. H6: Increases in the level of locally developed marketing knowledge will enhance the relationship between the level of knowledge transfer and marketing performance of the receiving subsidiary. The research framework that illustrates the proposed hypotheses is presented in figure 1. The unit of analysis for this study is knowledge transfer from the MNCs' headquarters and other subsidiaries to their subsidiaries operating in South Korea. The population for this study consists of subsidiaries established either as joint ventures or as wholly-owned subsidiaries. A group of 603 foreign firms were drawn from diverse industry organizations and business societies. After personal contact, telephone, fax, and e-mail to request that the respondents complete the questionnaire, 282 valid questionnaires from 133 initial sample companies were collected. The results of the empirical analyses significantly support all of the proposed hypotheses except hypothesis 3. Adaptability of external knowledge promotes knowledge transfer and the relationship is moderated by a firm's potential knowledge absorptive capacity. On the other hand, knowledge transfer improves a firm's marketing performance and a firm's realized knowledge absorptive capacity and local marketing knowledge moderate the relationship. The theoretical and practical implications of the findings in this study are as follows: (1) firms must take seeking, transferring, sharing and exploiting of external knowledge into serious consideration, while simultaneously creating knowledge to support the necessary business operations, remain competitive, and achieve superior performance. (2) Firms should continuously seek to develop their knowledge absorptive capacity (both potential and realized capacity) to absorb, learn and utilize valuable external knowledge. (3) Firms should emphasize not only absorptive capacity, but also development of local knowledge. Firms with strong absorptive capability and local knowledge can learn and transfer more external knowledge, which can be translated into greater levels of competence and performance.

  • Knowledge classification and expression of constructed knowledge have been main research issues in the field of knowledge representation. Constructed design knowledge of the former product loses its utility when new products with different structures are introduced to the market. In order to construct the design knowledge for a new product. designers need to reconstruct the design knowledge with new relationships. The design knowledge has been constructed with level trees, but it is difficult to rearrange the relations. Design DNA is proposed in this work in order to facilitate the rearrangement of design knowledge and give flexibility to knowledge structure. Design DNA is based on Layout-oriented domain knowledge and Function-oriented domain knowledge, which enables to generate new design knowledge that will result in new part geometries for given constraints on the part functions. Design DNA is applied to the design knowledge of lever system of the automatic transmission of passenger cars as an example.

  • Today a knowledge management systems (KMS) is an enabler for gaining competitive position in the market environments. However, it is just recognized as a conceptual management paradigm not as realistic management philosophy in an organization. A firm just accustomed to deal with tangible assets such as inventory and buildings based on the cumulated experiences. However, the firm often struggle with how to define and apply the knowledge management system into its real business activities such as business strategy and productivity. For example, one of textile company, E-land, in Korea found the way how the firm utilize intelligent assets of its employees to overcome the performance differences among the employees in an organization to increase their ability. Managers in an organization should fully understand and try to figure out the concept of knowledge management systems to implement KMS more efficiently and effectively. Even though lots of previous knowledge management literature proposed several unique knowledge management process models, they have their own terms, process sequences, or different approaches. There are three common knowledge management processes: knowledge creation, knowledge store and search, knowledge sharing process. In this study, a new KM process theoretical framework based on the previous researches is developed. This study will guide to those who will adopt or implement of KMS in the organization in near future.

  • 기업체의 경우 지식의 창출, 공유, 활용이 조직의 전 부서에서 발생하고 있기 때문에 자료실 정보시스템 또는 지식관리시스템이라는 제한된 공간에서 수동적으로 수집되는 정보, 지식만으로는 이용자의 요구를 제대로 만족시킬 수 없다. 따라서 본 연구에서는 BPM(Business Process Management)이 활성화 되어 있는 은행 환경에서 은행의 일반 업무 및 조사를 지원해 주는 지식, 정보, 문서 등의 암묵적 지식과 형식적 지식을 수집, 공유, 활용할 수 있는 온톨로지 기반 지식 리포지토리 모형을 구현해 보았다. 국내 일반 은행 환경에 맞는 모형을 제안하기 위해서 은행의 지식 관리의 현황, 문제점 및 개선점 등을 네 개의 일반 은행의 각 지식관리자와 자료실 사서 그리고 30명의 은행원들을 대상으로 한 면담과 설문지 조사를 통해서 파악한 후, 이러한 조사 결과를 기초로 하여 모형을 구현하였다.
