  • 본 연구는 작업현장, 교육현장, 기타 시공간에서 작업자의 현재 상황이나 담당업무 맥락에 따라 개인의 숙련도나 학습 진도에 맞추어 비공식학습과 공식학습 모두 실시간으로 발생할 수 있는 개인 추천 서비스 구현을 목표로 한다. 이에 복합지식을 기반으로 실시간으로 코칭과 조언을 들을 수 있으며, 다차원적인 관계를 쉽게 검색하고 추천할 수 있는 개인 맞춤형 복합지식 지능화 추천 시스템을 설계하였다. 이를 위해, 복합지식 저장소와 복합지식관리 모듈을 개발하였다. 특정 산업분야에서는 장기적으로 축척되는 지식베이스를 근간으로 하여 전문적인 문제해결 혹은 코칭 서비스 등을 부가적으로 창출할 것으로 기대된다.

  • 본 논문에서는 설계 경험이 적은 설계자가 효율적으로 선급규정을 이용하여 선체설계를 할 수 있도록, 범용 전문가시스템 쉘(Shell)인 NEXPERT를 이용하여, 선체 구조설계를 지원할 수 있는 전문가 시스템을 개발하였다. 먼저, 기존의 Rule Scantling프로그램으로 부터 지식을 추출하고, 이를 바탕으로 객체지향개념에 의해 지식의 그룹핑과 계층화를 시도하였다. 또한, NEXPERT가 갖고 있는 외부 프로그램과의 접속기능(Callable Interface)을 이용하여 각종 설계에 필요한 프로그램과 실적선 데이타베이스를 접속하였다. 특히, Motif를 이용한 그래픽 사용자 인터페이스(Graphical User Interface : GUI)를 도입하였고, 설계자가 결과에 대해 검토를 할 수 있도록 Knowledge tracing 기능을 부여함으로써, 사용자 지향의 구조부재 치수 결정 지원 전문가 시스템을 개발하였다.

  • Purpose: The purpose of this study was to investigate hospital nurses' delirium screening for postoperative delirium, delirium knowledge, and delirium care using case scenarios at a tertiary hospital in Seoul. Methods: A total of 235 nurses working at surgical units participated in this questionnaire-based study. Five cases scenarios were developed based on diagnosed postoperative delirium cases. Data were collected from April 1 to May 1, 2021. Results: The delirium screening score was 4.20±1.17 out of 5. The delirium knowledge score was 34.35±4.57 out of 47. The delirium care score was 67.61±9.26 out of 92. The correlation between the delirium screening and delirium knowledge was statistically significant (r=.18, p=.005). The correlation between the delirium knowledge and delirium care was statistically significant (r=.25, p<.001). Conclusion: The findings showed that the continuing educations of delirium for hospital nurses and the development of a delirium education programs were important to improve delirium screening and care.

  • This study is to establish the domains and the standards of instructional evaluation on the teacher knowledge dealing with the knowledge of 'teaching and learning methods and assessment'. Especially, in this study, the instruction assessment standards are developed focused on the five types of mathematics competencies such as problem solving, communication, reasoning, connection, information and handling, which were emphasized in the mathematical curriculum revised in 2022. By the result, ten domains such as an instruction involving instruction goal and content, problem-solving competency, data treatment competency, learners' achievement level and attitude, communication competency, reasoning competency, connection competency, the assessment method and procedure based on the competency, the assessment tool development based on the competency, assessment result based on the competency were new established. According to those domains, the total 20 instructional evaluation standards were developed. This study is limited to consider the domain of 'teaching and learning methods and assessment' among the domains of teacher knowledge, while dealing with the elements of mathematics competencies in the standards. However, instructional evaluation standards reflecting these competencies should be developed in the other diverse domains of teacher knowledge.

  • 과거 산업화 시대와 비교하여 현대 지식사회에서는 노동력의 중심이 육체노동에서 지식 노동으로 이동되었지만, 지식근로자의 생산성에는 극적인 성과가 나타나지 않고 있다. 따라서 "현대경영학의 아버지"라고 불리는 피터 드러커의 사상을 기반으로 전문가, 성과, 집중, 자기관리, 인생의 후반부의 지식근로의 요인과 지식근로자의 생산성 결정요소인 과업, 혁신, 자율성, 교육, 품질, ICT활용능력과의 연관성에 대하여 연구한 결과, 지식근로의 요인에 있어서는 성과>집중>자기관리>전문가, 인생의 후반부 순으로 연관성이 높은 것으로 나타났다. 특히 지식근로자에게 모든 생산성 결정요소와 영향요인으로는 성과로 나타났다. 따라서 지식근로자는 "성과"를 중심으로 자신의 분야에서 끊임없는 정보의 탐색과 활용을 통하여 목표를 달성하고, 조직과 사회에 공헌하면서 더불어 살아가는 공동체를 형성하는 데 앞장서야 할 것이다.

  • Objectives: A learning organization was designed and implemented on the basis of the selection criteria and essential elements of knowledge translation theory. Methods: The learning organization was designed on the basis of biosafety harmonization criteria and risk management strategy and was implemented as the learning organization for biosafety management by the National Institute of Health, Korea Centers for Disease Control & Prevention. The effect of knowledge translation in the research institutions by evidence-based policy was verified. Results: The result of applying the knowledge translation theory involving all stakeholders showed a positive reaction in establishing and implementing biosafety management strategy and embodied risk assessment criteria and evoked sympathy with the necessity of learning and using of expert knowledge about risk assessment and risk management. All stakeholders initiated voluntarily action toward new human-network construction and communication between similar organizations. The learning organization's capability expanded the base of knowledge translation. Conclusion: These results showed that a learning organization could enhance the autonomous safety management system by diffusion of knowledge translation.

  • The purpose of this study was to examine the effects of brand knowledge on evaluations of brand extensions in fashion market. Here, consumer knowledge toward the parent brand was based on the brand and on the company which introduced the brand. The brand extensions were classified into brand-name extension and corporate-name extension. For this study, questionnaires were administered to 700 single women in twenties. The questionnaires were designed to measure brand extension evaluations and brand knowledge in terms of familiarity, use experience and self-assessed knowledge, evaluations of the attributes and attitudes based on the brand and corporate. Employing a sample of 621 women, data were analyzed by t-test. Major findings of this study are summarized as follows; 1) The higher the level of brand knowledge such as brand familiarity, brand use experience and self-assessed brand knoil- edge was, the higher positive effects were on the evaluations of brand-name extension. Also, evaluations of brand attributes and brand attitude positively influenced the evaluations of brand-name extension. 2) The higher the level of corporate knowledge such as corporate familiarity and use experience of product manufactured by the company was, the higher positive effects were on the evaluations of corporate-name extension. Also, evaluations of corporate attributes and attitude on corporate positively influenced the evaluations of corporate-name extension. These results demonstrate that positive knowledges and affects on the parent brand are transferred to its extended product through categorization process.

  • Mathematics preservice teachers' Mathematical Content Knowledge ("MCK") includes not only knowledge for mathematics, but also academic knowledge for school mathematics and mathematical process knowledge. We can consider the items in PISA 2012 as suitable tools to assess process knowledge as well as mathematical content knowledge because these items are developed by competent international educational experts. Therefore, the responses to items with the low percentage of correct answers in conjunction with the mathematical contents were analyzed with focus on FMC. The results showed the reasoning competency in responses using the conditions of the problem and of understanding the conditions after reading the complex problems within the context (i.e. the reasoning and argumentation competency, and communication competency) requires improvements. Furthermore the results indicated the errors due to a lack of ability of devising strategies for problem solving. Based on the foregoing results, the implications towards the directions of the education for the preservice mathematics teachers have been derived.

  • 규칙 기반 지식표현은 전문가 시스템의 지식을 저장하고 조작하는 기법중 가장 많이 사용되는 기법이다. 그런데 이 방법으로 표현된 지식의 양은 점점 많아지며, 그 관계가 복잡해지고 내용이 변경될 수 있기 때문에 지식베이스의 일관성 및 완결성을 유지하는 검증 시스템이 필요하다. 따라서 본 논문에서는 새로운 규칙이 첨가될 때 야기될 수 있는 오류를 구조적 측면과 의미론적 측면에서 검증한 후 자체 수정하거나 자체 수정이 불가능할 경우 전문가가 수정하도록 하여 일관성과 완결성이 확증된 후 새로운 규칙이 추가되어질 수 있도록 함으로써 전문가 시스템의 신뢰도를 높이고 효율성을 제고할 수 있는 검증시스탬이 제안되었다.

  • Grinding has difficulty in satisfying the qualitative knowledge based on the skilled expert as well as quantitative data for all user. Design of grinding database is based on the frame-based model for utilizing the empirical and qualitative knowledge. Inthis paper, basic strategy to develop the grinding database by frame-based model, which is strongly dependent upon experience and intuition, frame-base model, which is strongly dependent upon experience and intuition, is described. Design of grinding database is based on the frame-based model for utilizing the ambiguous knowledge and inference is accomplised by the object-oriented paradigm system.
