Today, It has developed actively e-learning according to web without time and place which increase of PC user with super-highway information network and various up-to-date information rapid growth. It has to provide the chance to student which will be able to practice and to think free and originative under liberal learning environment that learner can compose knowledge through various thinking by themselves. From the present paper, I would design e-learning system using TGT model of cooperative e-learning system that more effective studying through advantage of e-learning studying. I look forward to helping improvement of student's real ability as embody competitive games method by TGT model's basic theory of web-based.

This paper proposes a method to implement biological early warning systems(BEWS). This system generates periodically data event using a monitoring daemon and it extracts the feature parameters from this data sets. The feature parameters are derived with 6 variables, x/y coordinates, distance, absolute distance, angle, and fractal dimension. Specially by using the fractal dimension theory, the proposed algorithm define the input features represent the organism characteristics in non-toxic or toxic environment. And to find a moderate algorithm for learning the extracted feature data, the system uses an extended learning algorithm(UChoo) popularly used in machine learning. And this algorithm includes a learning method with the extended data expression to overcome the BEWS environment which the feature sets added periodically by a monitoring daemon. In this algorithm, decision tree classifier define class distribution information using the weight parameter in the extended data expression. Experimental results show that the proposed BEWS is available for environmental toxicity detection.

Although online education has many advantages such as providing huge information and overcoming time and space limit over the traditional education, its effects may not be good unless proper user interface is not provided. Only well-designed interface can allow students to learn correct information quickly and study creatively and actively. The purpose of this study is to design and implement user interface suitable for elementary school students. In this study, in order to design proper user interface for elementary school students, factors affecting human-computer interaction have been analyzed and adopted. Also, design and structure of existing educational portal sites are analyzed so that the most common design elements are adopted. Finally, extensive survey is carried out in order to examine preference and navigation style of elementary school students and teachers. The survey results are reflected on the design principles of this work.

The purpose of this study was to identify the antecedents of organizational innovativeness, which in turn influence firm performance that is composed of new product development performance and overall firm performance. We collected responses from C-level executives, and conducted a structural equation model analysis. Results revealed that organizational memory and market orientation influence organizational innovativeness, which in turn influence new product development performance and overall firm performance. However, interestingly, new product development performance was not found to affect overall firm performance. Based on these results, we have confirmed the importance of market orientation and organizational memory for organizational innovativeness. Practical implications related to the results are provided.

제6세대 컴퓨터로 불리는 신경컴퓨터는 학습과 병렬처리에 의해 인간의 두뇌 기능을 모방한다. 인간의 두뇌는 시각인식, 음성인식, 촉각감지 등 패턴인식뿐 아니라 인간의 복잡한 신체구조를 시각, 촉각 같은 감각기관의 도움을 얻어 움직이는 중요한 역할도 한다. 바로 이 모터제어(motor control) 역시 신경회로가 담당하기 때문에 이를 기계적 신체에 해당하는 로보트 또는 광범위하게 기계, 비행기, 산업공정에 응용하는 것은 매우 자연스럽게 보인다. 이처럼 신경회로가 제어에 응용되는 것을 신경제어 (neurocontrol)라 하고 이를 이용한 기계를 지능기계(intelligent machinery)라 한다. 지능기계는 기본적으로 인간처럼 경험축적 학습 불확실한 환경에서의 적응 자기진단 등의 장점을 가지고 있다. 신경회로의 지극히 광범위한 응용분야중 신경제어는 가장 먼저 실현될 가능성이 높다. 실제로 로보트나 공정제어(process control)처럼 복잡한 비선형 시스템의 제어는 다량의 센서 정보에 기초한 실시간 제어를 필수로 하며 이는 신경회로를 사용함으로써 가장 효율적, 경제적으로 구현할 수 있다. 실제로 신경제어는 전세계적으로 이미 시스템 제어에 응용되어 좋은 결과를 내고 있다. 신경회로의 로보트나 자동화 응용은 학술적인 측면에서는 복잡한 비선형 시스템의 지능제어 (intelligent control)문제에 대한 신선한 해결책을 마련해줄 뿐 아니라 산업자동화라는 막대한 시장을 뒤로 하고 있어 이론에서 실제에 걸쳐 가장 광범위한 파급효과를 가지는 최첨단 기술로 보여진다. 고부가가치 상품을 통한 국제 경쟁력 제고의 차원에서도 정부, 기업 등의 과감한 연구 개발투자가 선행되어야 한다. 특히 이 분야의 연구는 선진국도 최근에 시작한 점으로 보아 정부, 기업이 이에 대한 연구 개발투자를 현명하게 할 경우에 세계적 기술 경쟁력도 확보할 수 있을 것이다. 본 해설에서는 로보트 및 시스템 제어에 관한 기초 이론을 설명하고 신경회로 적용기술을 소개하고 기존 방법과 비교 했을 때의 우월성, 전세계적인 응용연구, 국내외 연구개발 현황, 상업화 가능성, 산업계 응용례, 기술상의 문제점, 향후 전망 등을 다루기로 한다.

The purpose of this study was to analyze the pre-service teachers' perception for education paradigm and teacher's teaching competency in the fourth industrial revolution era. For this study 53 pre-service teachers participated in the discussion instruction during one semester. The study result was to analyze the discussion reports of pre-service students using the grounded theory approach. As a result, the pre-service students responded that the school needs to change the learner-centered education and assessment method in the fourth industrial revolution era. Secondly, the result of the teachers' teaching competencies was the integrated curriculum reconstruction, information processing, empathy and understanding, creative teaching and instructional design, collaboration and communication. This study is expected to contribute to the change of education paradigm for pre-service teachers in the fourth industrial revolution era.

e-learning has been recently introduced in all educational domains and it has expanded rapidly in educational field. Blended learning, which has emerged with e-learning nowadays, is an exact example of a new paradigm. It has not only educational effects of traditional classroom learning, but it also has effects of e-learning which provides learner-centered classroom environment and removes barriers of time and space. This study looked into several e-learning contents evaluation criteria that were already studied, And arranged with the evaluation question item that can evaluate learning effectiveness of e-learning contents in elementary school through a questionnaire executed in elementary school teachers. And it used this evaluation question item and the study accomplishment results of an education ruler, and applied to learning effectiveness evaluation of e-learning contents. This paper will give future directions and assessment criteria of e-learning. Moreover, this thesis will provide theoretical and practical materials for developing e-learning contents to improve quality of blended learning.

The object of this paper is to make learners have study environment to study adaptively, anywhere, anyone, anytime and, just in time, not disturbed by time and place. So, it helps learners find solutions to questions and problems which they can face in the process of learning. This paper desires to find possibility of ontology which can solve problems after considering semantic web and theory of ontology by studying existing reference books. As ontology has the structure that can guess the data which is not showed clearly, so it can make the result more accurate and be the knowledge every learner sympathize and trust. I established the ontology frame about the electronic circuit which learners can solve their questions everywhere, anytime, and reconfirm what they studied, so I studied on application for e-learning based on ontology.

학교 교재원은 생명과 환경 관련 교과 교육을 위한 가장 효과적인 학습 교재일 뿐 아니라 학생들의 성장 발달에 큰 영향을 줄 수 있는 곳이지만 학교 현장에서는 학교 교재원 관련 기준이 제정되어 있지 않으며 관리 장부도 허술하다. 또, 식물관리에 관한 기술이나 이론을 겸비한 전문가가 거의 없으며, 교재원 관련 고급 인력을 배치하기도 쉽지 않은 상황이다. 따라서 식물 및 교재원 관련 정보를 데이터베이스화하고 커뮤니티를 통해 정보를 교류하여 교재원 관리자가 관리를 좀 더 체계적으로 할 수 있게 돕고, 학생들이 좀 더 계획성있게 설계된 교재원을 접할 수 있도록 하는 교재원 관리시스템을 제안한다. 본 연구에서 제안하는 관리시스템으로 관리자는 좀 더 전문적이고 수월하게 교재원을 관리하고, 자라나는 학생들은 좀 더 다양한 과학적 자극을 받을 수 있을 것으로 기대한다.

Neural network is a very exciting and generic framework to develop almost all ranges of machine learning technologies and its potential is far beyond its current capabilities. Among other characteristics, neural network acts as associative memory obtained from the values structurally stored in synaptic inherent structure. Due to innate complexity of neural networks system, in its practical implementation and maintenance, multifaceted problems are known to be unavoidable. In this paper, we present design and implementation details of GUI software which can be valuable tool to maintain and develop neural networks. It has capability of displaying every state of synaptic weights with network nodal relation in each learning step.
