학습 객체는 생산 및 효율성과 구성주의적 학습 효과성을 겸비하면서, 컴퓨터 기반 학습 환경에 잘 적용될 수도 있는 차세대 학습 개념으로 각광 받고 있다. 그 탄생의 연원을 소프트웨어 공학에서의 객체지향 설계 이론에 기초한 이 학습 객체 설계 이론은, 그러나 학습자라는 학습의 주체에 대한 고려의 부족, 맥락성과 연계성, 그리고 의미론적 응집성이라는 "학습"의 논리를 담아내기에 충분한 수준의 이론적 기반을 갖추고 있지 못한 것이 현실이다. 본 연구에서는 학습 객체 설계 이론이라는 독특한 설계 모델을 지향하면서, 그 기초 작업으로서 관련 이론들을 정리해 내고, 메타포 수준의 개념틀 속에 자리 잡아 두며, 나아가 그 설계를 위한 원리들에 대한 분석을 시도하였다. 본 연구는 향후 구체적인 개발 사례를 통한 실증 연구와, 아울러 LCMS, 하이퍼텍스트의 노드와 링크 개념 등과 연결되면서, 본격적인 디지털 학습 콘텐츠 개발을 위한 이론을 지향하는 이론 연구로서의 의미를 갖는다.

Simulation-Based Expert System(SIMBES) is a very effective tool to solve complex antral hard problems. The SIMBES model includes a simulator, a feature extractor, a machine learning system, a performance evaluator, and a Knowledge-Based Expert System(KBES). Since SIMBES depends on Problem domains, a schedule-based material requirements planning problem, which is NP-hard, was selected to exemplify the SIMBES model. To implement the SIMBES application in Smalltalk paradigm, a system class hierarchy was constructed. The hierarchy consists of five large classes such as Job Generator, Job Scheduler, Job Evaluator, Inference Engine, and Executive System. Several classes inside these classes were identified. Additionally, instance protocols about all classes have been described in terms of messages and pseudo methods. These protocols can be implemented easily by any other object-oriented languages. Furthermore, these results may be used as a skeletal system to develop a new SIMBES efficiently, especially when the application is related to other scheduling problems.

To enable a relevance feedback paradigm to evolve itself by users' feedback, a reinforcement learning method is proposed. The feature space of the medical images is partitioned into positive and negative hypercubes by the system. Each hypercube constitutes an individual in a genetic algorithm infrastructure. The rules take recombination and mutation operators to make new rules for better exploring the feature space. The effectiveness of the rules is checked by a scoring method by which the ineffective rules will be omitted gradually and the effective ones survive. Our experiments on a set of 10,004 images from the IRMA database show that the proposed approach can better describe the semantic content of images for image retrieval with respect to other existing approaches in the literature.

나이브 베이시안은 기계학습에서 많이 사용되고 상대적으로 좋은 성능을 보인다. 하지만 전통적인 나이브 베이시안 학습의 환경은 두 가지의 가정을 기반으로 학습을 수행한다: (1) 각 속성들의 값은 서로 독립적이다. (2) 각 속성들의 중요도는 동일하다. 본 연구에서는 각 속성의 중요도가 동일하다는 가정에 대하여 새로운 방법을 제시한다. 즉 각 속성은 현실적으로 다른 중요도를 가지며 본 논문은 나이브 베이시안에서 각 속성의 중요도를 계산하는 새로운 방식을 제안한다. 제안된 알고리즘은 다수의 데이터를 이용하여 기존의 나이브 베이시안과 SBC 등의 다른 확장된 나이브 베이시안 방법들과 비교하였고 대부분의 경우에 더 좋은 성능을 보임을 알 수 있었다.

최근 들어 '학습자 중심의 자기주도 학습' 이라는 새로운 교육패러다임에 대한 관심이 집중되면서, 문제중심학습(Problem-Based Learning; PBL)이 학생의 과학적 사고능력 및 지식의 확장, 적용력, 비판적 지식창출 능력, 창의적 문제해결 능력을 향상시킬 수 있는 방법으로 주목받고 있다. 기계공학 분야에서도 이러한 PBL교육기법을 적용한 교과과정 개발에 대한 노력들이 활발히 전개되고 있으며, 본 논문에서 제시하는 '제품해체 설계추론'교과목도 그러한 교육방법을 적용한 한 예시라 할 수 있다. 제품해체 설계추론은 제품개발에 있어서 그 기여도가 가장 높은 기초물리학이 실제 제품에 어떻게 응용되고 있는가를 학생들이 직접 참여하여 체험할 수 있게 하는 제품해체 학습법 (product dissection)을 도입하여, 설계추론(design reasoning)에 있어서 기초물리학의 중요성을 인식시키는 한편, 다양한 기초과학에 대한 흥미를 유발할 수 있는 실습위주의 교과목이라 할 수 있다. 이러한 교과목을 통하여 창의적 설계 인력 양성에 큰 역할을 할 수 있을 것으로 기대한다.

The purpose of this study is to development of a teaching-learning model for active learning in engineering education. For this, the adequacy between educational objectives and active learning activities is verified and furthermore an "active learning teaching-learning model" is suggested. This suggested teaching-learning model is expected to supplement weakness of traditional lecture-type teaching-learning activity. Based on the literature review, first, the representative activities of active learning were derived. there are twenty active learning activities, which compose of five of individual learning activity, five of pair-learning activity and five of group-learning activity, and five of alternative- learning activity. In addition, a survey on adequacy between designed active learning activities and learning outcomes were conducted to ten educational experts. Lawshe's content validity calculation method was applied to analyze the validity of this study. Second, five teaching-learning principles, such as thinking, interaction, expression, reflection, and evaluation were derived to develop an "active learning teaching-learning model" which supplements lecture-type classes and then the "TIERA teaching-learning model" which consists of five stages was designed. Finally, based on the survey on educational experts, adequate active learning activities were proposed to apply in each stage of the "TIERA teaching-learning model" and as a result the TIERA model's active learning activities were developed. The result of this study shows that some activities of active learning are appropriate to induce high cognitive learning skills from the learners even in traditional lecture-type classrooms and therefore this study suggests meaningful direction to new paradigm of teaching-learning for engineering education. This study also suggests that instructors of engineering education can turn their traditional teaching-learning activities into dynamic learning activities by utilizing "active learning teaching-learning model".

This article tried to show a new paradigm for elementary school counseling in Korea. Counseling in Korean elementary school has focused on the individual child and/or group of the children without considering school circumstances. But school has some special features which have to be counted for the efficiency of child counseling. Take for an example, children have to spend most of their day time with a class teacher for 6 days a week. So the talks and behaviors of the class teacher have strong influence on the children. These factors should be included in the elementary school counseling to help children grow up and develop. : Six main topics discussed in this articles were as follows. 1. Developmental tasks of Korean children have to be searched and organized. 2. The concept of class management has to be combined with the concept of counseling. 3. Establishing the conditions to facilitate subject learning has to be emphasized in the school counseling. 4. Counseling instruments applicable to the children should be developed. 5. The proper knowledge of teacher's way cf talking and behaving in class life should be organized. 6. The resources of school counseling should be identified and interconnected to provide better counseling service to the children.

The recent medical education paradigm shift from teacher-centered to student-centered education, has led to a concentration on students' performance and competency. This means that a physician should be able to provide adequate health care in any real medical treatment situation. In order to reflect such a paradigm shift, The Catholic University of Korea School of Medicine launched a new curriculum in 2009 that emphasizes students' performance and competency-based education, known as "outcome-based education." In outcome-based education, the educational process is determined by the desired outcome, signifying the detailed competency that a graduating student should have. Thus, in outcome-based education, we should first determine the competency that results from adequate training and education, followed by specific teaching and learning strategies, methods, and assessment. This paper reviews how The Catholic University School of Medicine developed its new curriculum according to the development steps of outcome-based education.

Today, further education of adults in the UK is one of the developing areas of continuing education. The Open University with distance learning, in the process of which innovative forms and methods based on computer and telecommunication technologies are used, is particularly successful in the organization of additional education of the adult population. The advantages of distance learning, multimedia - the latest information technologies, which provide the combination of graphic images, video, sound with the help of modern computer tools, are noted. The basic principles and forms underlying the technologies and forms of work with the elderly are defined. The international experience of implementing "Universities of the Third Age" is summarized. The most widespread approach in adult education in Great Britain is informational. The use of computer technologies motivates a new paradigm in educational methods and strategies, which requires new approaches, forms of learning, and innovative ways of delivering educational materials to adult learners. Information technologies have gained great popularity in such activities as distance learning, online learning, assistance in the education management system, development of programs and virtual textbooks in various subjects, online search for information for the educational process, computer testing of students' knowledge, creation of electronic libraries, formation of a single scientific electronic environment, publication of virtual magazines and newspapers on pedagogical topics, teleconferences, expansion of international cooperation in the field of Internet education. The information technology of synchronous distance learning "online" has gained considerable popularity in the educational process today. A promising direction is the use of multimedia technologies in educational activities to create a design of a virtual computer environment by decoding audiovisual information.
