일반적으로 자기구성 지도에서는 구조가 초기에 결정되어 학습이 끝날때까지 변하기 않기 때문에 각 문제에 대한 구조를 반복된 실험을 통해서 최적화시켜야 한다. 그러나, 지도의 구조가 학습중에 적절하게 변경된다면, 해당 문제에 가장 알맞은 구조의 지도를 생성할 수 있을 것이다. 이 논문에서는 기존의 적응형 자기 구성 지도의 비교사 학습방법에 LVQ 알고리즘을 이용한 교사 학습방법을 결합한 구조 적응형 자기 구성 지도 모델을 제안한다. 이 방법은 일반적인 자기구성 지도 알고리즘보다 작은 수의 노드를 가지고 높은 성능을 보일 뿐만 아니라, 자기 구성 지도의 특성인 위상 보존도 잘 이루어진다. 오프라인 필기 숫자 데이터로 실험한 결과, 제안한 방법이 유용함을 알 수 있었다.

인터넷의 방대한 자료 중 필요한 자료만을 선별하고, 분석.종합하여 유용한 정보를 도출하는 능력이 더욱 더 요구되고 있다. 유용한 정보를 도출하기 위해서는 컴퓨터가 가지고 있는 정보처리 능력을 최대한 활용할 수 있어야 하며 교수자는 학습자에게 문제해결을 할 수 있도록 정보활용 능력을 길러주는 것이 교수자의 역할이다. 본 연구는 WWW에서 학습자와 학습자료간의 상호작용이 가능하도록 하였으며 학습자 상호간에도 상호작용이 가능하도록 공동학습장을 마련하였다. 또 교과학습을 효율적으로 하기 위해 홈페이지 제작학습 및 정보 검색방법, FTP 사용법, 압축/해제하기 등을 탑재하여 효율적인 정보활용을 위해 기본적인 도구들의 사용법을 습득할 수 있도록 하였으며, 학습자가 인터넷 홈페이지를 활용하여 과제 학습을 자기 주도적으로 해결함으로써 정보활용 능력을 신장시키는 시스템을 제안하였다.

The current and ethnic issues represented in child-rearing practices of Korean-Chinese families in YanBian, China, were studied with the participation of 7 primary caregivers (4 mothers and 3 grandmothers) of young children who were interviewed and observed in their homes. Current issues were categorized as competitive bilingual ability, expectations about third language learning (English), expectations of high academic accomplishment and early education, and economic challenges in parenting. Ethnicity issues included ethnic pride as Korean-Chinese, conflicts of ethnic education, participation in local Korean culture, and rearing the child to have the self-expressive and assertive characteristics of typical Korean children. Results were discussed in terms of understanding and supporting child-rearing of minorities and families with multi-cultural background.

Listening comprehension is an integrative and creative process of interaction through which listeners receive speakers' production of linguistic or non-linguistic knowledge. Compared with reading comprehension, it may arouse difficulties and thus impose more burdens on foreign learners. The Audio-Lingual Method focused primarily on speaking. Mimicry, repetition, rote memory, and transformation drills actually interfered with listening comprehension. So learners lost interest and were not highly motivated. Improving listening comprehension requires continual attentiveness and interest. Listening skill can be extended systematically only when students are frequently exposed to a wide range of listening materials with an affective, cultural, social, and psycholinguistic approach. Therefore, teachers should help students learn how to comprehend intactly the overall meaning of intended messages. The literature on teaching listening skill suggests various useful activities: TPR, dictation, role playing, singing, picture recognition, completion, prediction, seeking specific information, summarizing, labeling, humor, jokes, cartoons, media, and so on. Practical classroom teaching necessitates a systematic procedure in which students should take part in meaningful tasks/activities. In addition to this, learners must practice listening comprehension trough a self-study process.

In this paper we propose a fast and precise control algorithm for a mobile robot, which aims at the self-tuning control applying two multi-layered neural networks to the structure of computed torque method. Through this algorithm, the nonlinear terms of external disturbance caused by variable task environments and dynamic model errors are estimated and compensated in real time by a long term neural network which has long learning period to extract the non-linearity globally. A short term neural network which has short teaming period is also used for determining optimal gains of PID compensator in order to come over the high frequency disturbance which is not known a priori, as well as to maintain the stability. To justify the global effectiveness of this algorithm where each of the long term and short term neural networks has its own functions, simulations are peformed. This algorithm can also be utilized to come over the serious shortcoming of neural networks, i.e., inefficiency in real time.

최근 학교 현장에서는 전통적인 교수 학습 방법을 탈피한 정보통신기술을 활용한 교수 학습 방법은 거스를 수 없는 정보화 사회의 새로운 교수 학습 모형으로 보편화되어 가고 있다. 이에 본 연구에서는 현실 여건을 개선하고 교육과정이 요구하는 목표 달성을 위하여 학생들의 인터넷 사용의 대부분을 차지하는 커뮤니티 활동을 미니홈페이지라는 공간을 통해 교사와 학생 사이에 학습과 대화의 장으로 활용하기 위해 ICT 활용 교육 커뮤니티를 구축하였다. 이를 활용하여 학생들이 학습에 대한 관심과 흥미를 유발하고 시간과 장소에 구애를 받지 않으며 학생 자신이 주도적으로 학습 과제를 해결하는 학습과정으로 교수 학습 방법의 개선을 통하여 학생의 자기주도적 학습 능력이 신장되도록 ICT 활용 교육을 활성화하여 ICT 활용 교육이 우리 학교 현장에 튼튼히 뿌리를 내리는 데에 기여하고자 HTML학습을 위한 홈페이지를 블로그툴을 이용하여 구현하였다.

21세기의 세계화, 정보화 시대를 주도할 자율적이고 창의적인 한국인을 육성하기 위하여 제7차 교육과정은 자율과 창의에 바탕을 둔 학생 중심의 교육과정을 표방하고 자기 주도적 학습 능력의 신장에 역점을 두고있다. 이에 따라 자기 주도적 학습 능력신장을 위한 수학과 교수 학습 자료들이 제작되어 보급 활용되고 있으나 구체적 조작기 아동의 특성에 맞는 초등학교 저학년 수학교과의 자기 주도적 학습 능력 신장을 위한 효과적인 프로그램은 부족한 실정이다. 이에 본 연구는 선행 연구 사례들을 분식하여 나타난 단점들을 수정, 보완하고, 초등학교 '확률과 통계'영역 중 3학년 나 단계의 '자료 정리하기' 단원을 재구성하였다. 그리고 이를 웹기반 학습 프로그램으로 개발하여 현장에 적용해 봄으로써 그 효과를 검증하고자 한다.

The paper examined effect of age cohort on life cycle financial planning. A total of 990 questionnaires were distributed with a 55.2% return rate. Seven hypotheses were analysed using hierarchical and ordinary regression analysis. The results revealed that age cohort variables made significant contribution to life cycle financial planning as well as personal orientation towards retirement planning, particularly the younger age cohort. Age cohorts do affect personal orientation towards retirement planning with the confidence level making a significant impact. Current financial resources do have a strong positive impact on consumption for all age cohorts. On the other hand, no significant effect was found between age cohorts and current financial resources but older age cohorts were relatively more significant predictors. The implication was that not only should their individual perceptions of financial planning become an increasingly important part of people's long-term commitment throughout their life-cycle, it must also assume the role as a self-directed life-long learning process, in view of the ever-changing and complicated financial environment.

Our prediction model is based on the development of "Semantic Location Model." It embodies geometrical and topological information which can increase the efficiency in prediction and make it easy to manipulate the prediction model. Data mining is being implemented to extract the inhabitant's location patterns generated day by day. As a result, the self-learning system will be able to semantically predict the inhabitant's location in advance. This context-aware system brings about the key component of the ubiquitous computing environment. First, we explain the semantic location model and data mining methods. Then the location prediction model for the ubiquitous computing system is described in details. Finally, the prototype system is introduced to demonstrate and evaluate our prediction model.

The objectives of this study were to inquiry of application types and use methodology of EBS-CSAT prep books of vocation education division in specialized vocational high schools. Research participants are 8 specialized vocational high school teachers in Seoul and Gyeonggi, and subjects are basic industry and basic drawing. The teachers had using EBS-CSAT prep books in class or after-school. The results are as follows: The teachers used items explanation of after-school rather than regular classes using EBS-CSAT prep books of vocation education division in specialized vocational high schools. Online lectures were used for self-directed learning of specialized vocational high school students rather than regular classes. Students and teachers of specialized vocational high school needed EBS-CSAT prep books of vocation education division by free gift instead of EBS-CSAT prep books of Korea language, english, math.
