본 논문에서는 얼굴 인식을 위하여 인공 신경망의 일종인 Extreme Learning Machine의 학습 알고리즘을 기반으로 하여 지능형 알고리즘인 퍼지 집합 이론을 이용하여 주변 노이즈에 매우 강한 특성을 보이며 학습 속도가 매우 빠른 새로운 패턴 분류기를 제안한다. 제안된 퍼지 패턴 분류기는 기존 신경회로망의 학습 속도에 비해 매우 빠른 학습 속도를 보이며, 패턴 분류기의 일반화 성능이 우수하다고 알려진 Extreme Learning Machine의 특성을 퍼지 집합 이론과 결합하여 퍼지 패턴 분류기의 일반화 성능을 개선하였다. 제안된 퍼지 패턴 분류기는 얼굴 인식 데이터를 이용하여 성능을 평가 하였다.

Recently, the advent or WWW widely increased computer-mediated instruction and a majority of Web-based instruction lack interactive capabilities. In this study. we propose a adaptive Web-based courseware model with learner's motivates and design database tables in order to apply using button theory. Therefore, we design database tables which is diagnosed learner's status within each windows with contents for checking motivation to learn itself via Web-based cyber instruction.

This study is a case study comparing and examining the effects of non-face-to-face(NFTF) classes in the 2021-2 semester and face-to-face(FTF) classes in the 2022-2 semester on learning immersion, learning stress, and learning satisfaction. The learning immersion and learning satisfaction of 240 students were analyzed in NFTF and FTF classes of department S of C junior college where the same textbook, same subject, and same professor were taught. For data processing, SPSS Ver. 23.0 was used. The data is used to measure reliability by Cronbach's α, t-test, Pearson's correlation coefficient, and multiple regression analysis. The results of this study are as follows. First, learners' learning immersion was higher in FTF than NFTF classes among engineering major subjects. Second, it was found that there was a difference in learning stress according to the types of FTF and NFTF classes in engineering major subjects. Third, it was found that there were differences in practice content, communication, and task performance of sub-factors of learning satisfaction according to FTF and NFTF class types in engineering major subjects. In conclusion, it was found that FTF classes had a more positive effect on learning immersion and satisfaction, and NFTF classes had a more negative effect on learning stress.

In this paper, we aim to draw up an alternative instruction scheme by designing a web based instruction model on mathematics. Some learning materials are developed according to the scheme, and its educational effects are examined when it is committed to through regular curriculum. The study is composed of three major parts; setting of the theoretical foundation on cultivating Web based educational materials, design and composition of Web based teaching-learning model, and its experiments in the regular class. First of all, we are concerned with the core principles on WBI including the learning theories, developing learner oriented instruction model, design as well as build-up process for education materials, and strategy in instruction. Next, we propose an alternative instruction model for mathematics, in which programs to embody mathematics education and instruction on the Web are constructed, on the while, the study is proceeded through the Web Site. Finally, we design and produce a WBI instruction model on the subject of the plane quadratic curves. This model is examined in the regular class to estimate its educational effects compared with traditional teaching standpoints. Concomitantly, we explore essential elements and the direction of future growth associated with the Web oriented education.

Fuzzy set의 또 다른 장점은 "학습"을 함으로써 시간에 따라 변하는 환경에 대해서도 적용이 가능하다는데 있다. 학습하는 Fuzzy 인공지능의 필요성은 목표하는 바가 복잡할수록, 그리고 신뢰도가 떨어질수록 그 중요성을 더해간다. 이 Fuzzy System의 학습과정은 특히 "Unsupervised Learning"이라는 목표하에 그 연구열이 점점 더해가고 있다. 수년안에 사람들간에 이러한 대화가 오고갈 것은 명백해진 것 같다.화가 오고갈 것은 명백해진 것 같다.

6차 교육과정이 추구하는 인간상의 하나가 "창의적 사람"이다(대천 교육청, 1994). 앞으로 다가올 21세기는 정보화 사회, 다원화 사회, 세계화 사회가 될 것으로 전망되며, 국가간의 무한 경쟁 시대에 대처하기 위해서는 종래의 방법과 가치관에 의한 교육의 틀에서 탈피하여, 창의력을 기르는 교수-학습 지도 방법이 있어야 할 것이다.(중략)할 것이다.(중략)

As tourists travel to other regions, they encounter numerous facts that conflict with their views. At that time, we change our view of coping with life. In this respect, tourism is a new way of learning. As a new learning method, tourism experience research is a new approach. In this study, the relationship between experience and learning experienced in tourist destinations was analyzed by applying the activity theory. The analysis units applied in the activity theory were set as subjects, goals, communities, roles, methods and rules, outcomes, and relevance to local communities. Based on this, in-depth interviews were conducted with commentators and guides who had a great influence on the tourism experience to analyze the learning process of tourists. As a result of the analysis, the experiences of tourists during the tour were interactive in various forms within the unit as well as the unit of the activity system of the commentator and guide. This interaction induces changes in the tourism experience activity system, enabling tourists to learn. The content is that the value of learning increases as the role of guide and commentator increases, that the social and cultural dimension of tourism experience is included in the learning effect, and the contradictions that arise from interactions within or between activity systems. The fact that they find the solution process themselves, and that tourism activity is not an isolated unit, but exists at the intersection of hierarchies and networks, is affected by the activities and environments of others.

The COVID-19 Pandemic incident forced all educational and learning activities to move online, so it is no longer an option to use information and communication technology for education and learning. Venture capital has made the largest investment ever in Edu-tech startups. This study investigates the factors influencing the intention to use digital technology in education, taking into account the Unified Theory of Acceptance and Use of Technology (UTAUT) along with digital literacy, which has become an essential ability in the digital age. As a result of the structural equation model analysis, we find that performance expectation, effort expectation, and social influence have a positive effect on the intention to use digital technology in education. Moreover, digital literacy has a positive effect on performance expectation, effort expectation, and social impact, but the direct effect on the intention to use digital technology on learning is not significant. Furthermore, to see the moderating effect of age, the results of multi-group analysis present that the differences between 10s and 60s, between 20s and 60s, between 30s and 60s on the path of social influence on the intention to use digital technology in education are significantly reduced. This study academically contributes to expanding the research on the factors affecting the intention to use digital technology in a specific situation of education by considering both digital literacy and Unified Theory of Acceptance and Use of Technology (UTAUT). In addition, it can be used as a practical guide to the factors to be considered for each age when making learning participants more actively use digital technology.

수학의 내용을 학생에게 지도할 때 기계적인 계산법칙을 가르치는 것보다 개념을 이해할 수 있도록 돕는 것은 교사의 중요한 역할이다. 그 동안 연구를 통해 정수를 지도하기 위한 모델들은 꽤 많이 알려져 왔으나 이 모델들을 학생에게 직접 적용하였을 때 일어나는 현상을 파악한 연구는 그리 많지 않다. 따라서 본 연구는 상위, 중위권 초등학교 5학년을 대상으로 EIS이론에 바탕을 둔 정수의 모델을 통해 학생들이 정수의 개념을 어떻게 형성하고 그 과정에서 어떤 오류를 나타내는지, 또 무엇을 가장 어려워하는지 등 그 학습과정을 조사하였다.
