This article describes a novel model-based compensating neural network (NN) model developed to be used in our active binocular head controller, which addresses both the kinematics and dynamics aspects in trying to precisely track a moving object of interest to keep it in view. The compensating NN model is constructed using two classes of self-tuning neural models: namely Neural Gas (NG) algorithm and SoftMax function networks. The resultant servo controller is shown to be able to handle the tracking problem with a minimum knowledge of the dynamic aspects of the system.

This study proposes University 2.0 as a model case of open, flexible, and distributed learning environment for higher education based on theoretical foundations and perspectives. As web 2.0 technologies emerge into the field of education, ways of generating and disseminating information and knowledge have been drastically changed. Professors are no longer the only source of knowledge. Students using internet often become prosumers of knowledge who search and access information through the web as well as publish their own knowledge using the web. A concept and framework of University 2.0 is introduced for implementing the new interactive learning paradigm with an open, flexible and distributed learning environment for higher education. University 2.0 incorporates online and offline learning environments with various educational media. Furthermore, it employs various learning strategies and integrates formal and informal learning through learning communities. Both instructors and students in University 2.0 environment are expected to be active knowledge generators as well as creative designers of their own learning and teaching.

최근 자연어 처리에서 사용되던 트랜스포머 모델이 이미지 초해상화 분야에서도 적용되면서 좋은 성능을 보여주고 있다. 그러나 이러한 트랜스포머 기반 모델들은 복잡하고 많은 학습 파라미터를 가지고 있어 많은 하드웨어 자원을 요구하기 때문에 작은 모바일 기기에서는 사용하기 어렵다는 단점을 가지고 있다. 따라서 본 논문에서는 트랜스포머 기반 초해상화 모델의 크기를 효과적으로 줄일 수 있는 지식 증류 기법을 제안한다. 실험 결과 트랜스포머 블록의 개수를 줄인 학생 모델에서 제안 기법을 적용해 교사 모델과 비슷한 성능을 내거나 더 높일 수 있음을 확인하였다.

Purpose: Knowledge, clinical reasoning, and self-confidence are the basis for undergraduate education, and determine students' level of competence. The purpose of this study was to assess the effects of the addition of a one-time simulation experience to the didactic curriculum on nursing students' knowledge acquisition, clinical reasoning skill, and self-confidence. Methods: Using a quasi-experimental crossover design consisted of intervention and wait-list control groups. Participants were non-randomly assigned to the first intervention group (Group A, n=48) or the wait-list control group (Group B, n=46). Knowledge level was assessed through a multiple choice written test, and clinical reasoning skill was measured using a nursing process model-based rubric. Self-confidence was measured using a self-reported questionnaire. Results: Results indicated that students in the simulation group scored significantly higher on clinical reasoning skill and related knowledge than those in the didactic lecture group; no difference was found for self-confidence. Conclusion: Findings suggest that undergraduate nursing education requires a simulation-based curriculum for clinical reasoning development and knowledge acquisition.

This paper deals with manufacturing process design of a simplified gun tube applying CE principle. A concept and characteristics of CE, mathematical model for understanding interaction between design and manufacturing, basic elements and related equations for process planning and cost estimating are introduced. A Knowledge-based Computer-Aided Process Planning System(KCAPPS) is constructed, yielding optimal production cost/time for the shape input and selection of appropriate machines and tools.

거대언어모델(LLM)에 대한 수요와 활용 사례가 증가함에 따라 사용자의 민감정보가 LLM 사용 과정 중에 입력 및 유출되는 위험성 또한 증가하고 있다. 일반적으로 LLM 환각 문제의 해결을 위한 도구로 알려진 지식그래프는, LLM과는 별개로 구축되어 사용자의 민감정보를 별도로 보관 및 관리할 수 있으므로, 민감정보의 유출 가능성을 최소화하는 하나의 방법이 될 수 있다. 따라서 본 연구는 사용자로부터 입력된 자연어 기반의 질문을 LLM을 통해 지식그래프 유형에 맞는 쿼리문으로 변환하고 이를 이용하여 쿼리 실행과 결과 추출을 진행하는 지식그래프 기반 챗봇을 제시한다. 또한 본 연구에서 개발된 지식그래프 기반 챗봇의 기능적 유효성 판단을 위하여, 기존 지식그래프에 대한 이해도와 적응력, 새로운 개체 클라스 생성 능력, 그리고 지식그래프 콘텐츠에 대한 LLM의 접근 가능성 여부를 판단하는 성능 테스트를 수행한다.

건설산업은 타 산업과는 다른 특수성을 가지고 있다. 이런 특수한 건설산업에서 지식경영을 실천하기 위해서는 현장을 중심으로 한 시스템적인 접근과 기업문화적인 접근이 동시에 요구된다. 하지만 대부분의 건설기업들은 지식경영을 실천하기 위해 시스템적인 접근에만 몰두하고 있는 것이 현실이고 그러한 이유가 건설기업 지식경영 실패의 원인이 되고 있다. 이러한 구조적 모순을 해결하고자 본고에서는 CoP를 기반으로 하는 건설기업 학습조직에 대 해 연구하였다.

As growth of the web-based applications, the requirements of the users who have been very familiar to the web-based user interfaces and customer-oriented services on the Internet would become more knowledge-intensive and higher technology involved in a more convenient and polite way of service delivery. Therefore, the service quality of information system department should be considered as a very important factor influencing success of information systems. The objective of this study is to provide the relationship between service quality of IS department and its impacts such as use, user satisfaction and job performance. For this purpose, we provide a research model for it and test it empirically for the users of the corporate portal in one of main telecommunication service providers in Korea. In result, our model with satisfiable validity and reliability shows not only importance of IS departments' service quality but also two-faced characteristics of service quality. That is, while technical competence which means with knowledge and expertise of IS department staffs is more related with user satisfaction on information systems, personal service which means the way and manner of service delivery is more related with use of it.

The construction drawing is a collection of knowledge that has accumulated knowledge and experience of designers and is highly valuable for recycling in the future. BIM is a process and technology that acquires and manages the information needed for the whole life cycle of a building. In order to recycle digitalized 2D drawings in BIM Tool, it is required to use 3D information based on the drawing information to save and reuse them, but there is little research on related methods or system development. In this study, 3D elements are created based on 2D drawing information, and libraries are constructed, and BIM Tool is used to improve the recyclability of drawing information.
