The purposes of this study are to identify the types of teacher efficacy, to present a theoretical base for teacher efficacy among Home Economics teachers and subsequently, to improve the quality in the practices of home economics education. To achieve these purposes, 263 secondary school home economics teachers were surveyed by the prime investigator. The three research questions of this study were: 1. What are the individual characteristics, the environmental characteristics and the trends of teacher efficacy among secondary school home economics teachers? 2. What is the factor in teacher efficacy among secondary school home economics teachers? 3. What are the types of teacher efficacy among secondary school home economics teachers? For these research questions, factor analysis and cluster analysis were conducted. The factor analysis on teacher efficacy with a survey of secondary school home economics teachers produced 5 factors of efficacy: classroom management, needs assistance, instructional strategies, environmental assistance and teaming assistance. The teacher efficacy had a mean of 3.58 and the home economics teachers showed a slightly higher level in teacher efficacy. Of the 5 efficacy factors, classroom management showed the highest level (M=3.89), followed by learning assistance (M=3.81), instrumental strategies (M=3.57), environmental assistance (M=3.42) and needs assistance (M=3.19). Overall, the teachers had positive feeling in teacher efficacy. Three types of teachers were found in the types of teacher efficacy: the supreme, the average and the efforts-needy. Those types were identified based on the mean scores of the five sub-domains from the factor analysis. To enhance the teacher efficacy, the needs assessments for the students and behavioral adjustment issues should be reflected in the curriculum of teacher education and workshops. The primary investigator suggested that continuous and long-term plans for teacher education need to be developed because short-term plans may not be effective in changing attitudes such as teacher efficacy.

Considering the present and expected demand for human resources by the maritime community, its quantity and quality depend on the number of the ships and the technology applied to them. Scientific and economic developments in this community bring the intensive use of modem technology for many of ships operation. Generally it effects to reduce the quantity of manpower, while it increases the requirement of qualifications of human resources to utilize such advanced technology. Considering above, the maritime education, training and research activities should be revised and updated according to the demand of the community. Because of a difference between the transition of the demand for the human resources and development of the maritime education, training and research activities, there are two most common questions as “What to teach” and “How to teach”. The first question has been asked for many years. The contents of maritime education and training are always related to the existing maritime knowledge and technology and should be updated with consideration of changes of the demand namely “Globalisation of maritime community”. It brings globalisation of the maritime education, training and research activities. The second question is still keeping us busy to look for the best way. Presently traditional methods are used together with new system, while the use of sophisticated simulation, communication and information systems etc. and it is changing our understanding on teaching. This paper introduces the new role of Maritime Institutions from the viewpoints of the maritime education. training and research activities. The role of guide for seafarers and maritime companies is always essential and the concepts such as “Refreshment Training”, “On the Job Training”, “Lifelong” or “Continuous Training” bring new understanding to the training period, trainee's age and position. As a result, the maritime institutions should be ready for their new role, which is, in brief, guiding the maritime society, recommending and providing new learning environments, organising research and developments, performing the education, training and assessment, improving existing methods and developing new methods of the education, training and assessment.

Objective:The present study examined the association between basic neurocognitive functions and emotional recognition in chronic schizophrenia. Furthermore, to Investigate cognitive variable related to emotion recognition in Schizophrenia. Methods:Forty eight patients from the Yongin Psychiatric Rehabilitation Center were evaluated for neurocognitive function, and Emotional Recognition Test which has four subscales finding emotional clue, discriminating emotions, understanding emotional context and emotional capacity. Measures of neurocognitive functioning were selected based on hypothesized relationships to perception of emotion. These measures included:1) Letter Number Sequencing Test, a measure of working memory;2) Word Fluency and Block Design, a measure of executive function;3) Hopkins Verbal Learning Test-Korean version, a measure of verbal memory;4) Digit Span, a measure of immediate memory;5) Span of Apprehension Task, a measure of early visual processing, visual scanning;6) Continuous Performance Test, a measure of sustained attention functioning. Correlation analyses between specific neurocognitive measures and emotional recognition test were made. To examine the degree to which neurocognitive performance predicting emotional recognition, hierarchical regression analyses were also made. Results:Working memory, and verbal memory were closely related with emotional discrimination. Working memory, Span of Apprehension and Digit Span were closely related with contextual recognition. Among cognitive measures, Span of Apprehension, Working memory, Digit Span were most important variables in predicting emotional capacity. Conclusion:These results are relevant considering that emotional information processing depends, in part, on the abilities to scan the context and to use immediate working memory. These results indicated that mul- tifaceted cognitive training program added with Emotional Recognition Task(Cognitive Behavioral Rehabilitation Therapy added with Emotional Management Program) are promising.

The purpose of this study is to investigate how fifth and sixth graders recognize average and to find out suggestions for teaching/learning methods of average by examining which difference there is depending on the way of the word problem presentation. For the this purpose, was conducted experiment study with the way of the world problem presentation set up as experimental treatment. The conclusions drawn from the results obtained in the this study were as follows : First, since students who did not learn the regular course of average had various informal concepts already, it is needed to consider handling more various concepts of average in order to enable students to expand flexible thoughts. Second, compared with fifth and sixth graders showed a wide difference in informal concepts of average depending on the way of the word problem presentation. In expect data with given average, concepts of mean as algorithm, balance point, and mode indicated similar percentage, while in estimate average with given data, the percentage of students who showed the concept of mean was very high at 67.6%. That may be because problems related to mean in the current textbooks are items of 'estimate average with given data', so in types of 'estimate average with given data', students solve questions with mean as algorithm without considering situations of problems. This result suggests that it is necessary to diversify the way of the word problem presentation even in textbooks. Third, as a result of analyzing informal concepts of average, there was significant difference in grades. In addition, the results suggested that there would be difference in the concepts of average depending on gender or attributes of discrete quantity and continuous quantity.

현대를 살아가는 현대인들이 경험하는 만성통증 및 디스크는 성인의 80% 이상이 경험하는 흔한 질병이다. 이러한 질환들 중 교통사고, 추락 등 물리적인 충격에 의한 발생율은 10%정도이며 대부분이 습관적으로 부적합한 자세를 취하게 되어 특정 부위에 지속적인 스트레스가 쌓여 발생하게 된다. 이처럼 부적합한 자세가 오랫동안 이어져 질환의 원인이 되는 것을 알면서도 고쳐지지 않는 이유는 지속적인 반복을 통한 습관화로 인하여 부적합한 자세를 바로 인지하지 못함으로써 바르게 교정하지 못하고 지속되어지기 때문이다. 따라서 본 시스템은 자세를 측정할 수 있는 센서들을 사용자에게 부착 후 사용자의 자세에 따른 데이터를 수집하여 정확한 자세를 측정하고 자세추정알고리즘을 이용하여 해당 자세의 적합여부를 추정한다. 사용자가 부적합한 자세를 지속적으로 취할 경우 이를 인지할 수 있도록 한다. 그리고 적합한 자세로 변경하도록 유도하여 부적합한 자세의 습관화를 방지하는데 목적을 두고 있다. 또한 부적합한 자세의 원인을 분석 후 제거하여 적합한 자세를 취하는데 보조자의 기능을 수행 한다. 정확한 측정을 통한 반복적인 인지 학습을 통해 올바른 자세를 습관화 한다면 성장기 어린이와 만성 질환자에게 많은 도움을 줄 것으로 생각 된다.

This study aims to examine both the theoretical framework and practical method for the building a subject-oriented collection of information resources form Internet. Through the study, a few conclusions as well as a suggestion were derived. 1. Conclusions : (1) The continuous learning and studying by the librarians working in the information society is required in order that they could have a broader recognition of the existence of various resources from Internet by subject, and that they could be armed with a greater ability to evaluate for the information filtering. (2) The use of a subject directory to collect needed information resources form Internet revealed the necessity for going through many steps linked by hierarchical indexes till arriving at the desired information, and accordingly the great time was needed to conduct the work. (3) In case of using various search engines, since the output of the relevant information largely depends on the adequate defining of the topic, the right selection of search terms and the accurate methods of inputting the keywords, systematic organization of the resources is not simple and easy. The classifying work of collected resources for the topic into the broader categories differs from that of the resources form other topics, for example, psychology, because of the idiosyncrasy of the contents of the each topic. (4) As one method to provide more revolutionary value-added service using Internet, it is necessary for the librarians to learn the skills to build the Web resource pages of subject-oriented collection of information resources from Internet on the specific subject. 2. A suggestion : Since the study did not complete the collection and organization of the information resources from the Internet on this topic, the remaining research and task should be the thorough collection of resources and the building the Web resource pages consisting of interconnecting links of indexes by spending greater time.

실시간영상에서 객체의 분할 및 추적은 침입자 감시와 로봇의 물체 추적, 증강현실의 객체 추적등 다양한 분야에서 사용되고 있다. 본 논문에서는 초기 입력 영상의 일부를 학습하여 배경모델로 제작한 후, 배경제거 방법을 이용하여 움직이는 객체의 분할을 통해 객체를 검출하였다. 검출된 객체의 영역을 기반으로 HSV 색상히스토그램과 파티클 필터를 이용하여 객체의 움직임을 추적하는 방법을 제안한다. 제안한 분할 방법은 평균 배경모델을 이용한 방법보다 주변환경 변화의 영향을 적게 받으며, 움직이는 객체의 검출 성능이 더욱 우수하였다. 또한 단일 객체 및 다수의 객체가 존재하는 환경에서 추적 객체가 유사한 색상 객체와 겹치는 경우, 추적 객체의 영역 절반 이상이 가려지는 경우에도 지속적으로 추적하는 결과를 얻을 수 있었다. 2개의 비디오 영상을 사용한 실험결과는 평균 중첩율 85.9%, 추적률 96.3%의 성능을 보여준다.

본 연구는 대학 원격강의의 질을 높이기 위한 연구의 발판이 되도록 현재 사용되는 대표적인 두 개의 화상 미팅서비스의 사용성 평가를 하는 것이다. 기능을 중심으로 분석하기 위해 카노모델(Kano)을 기반으로 한 질문지를 설계하여 반구조적 심층면담을 실시해 정성적인 접근을 꾀하였다. 두 서비스의 1차원적 기능인 화면공유 기능이 중요하게 여겨지고 있었고 매력적인 기능들은 비교적 다양한 방향성을 갖고 있었다. 꼭 있어야 할 기능인 카메라, 마이크의 경우 사용자에 따른 장비로 인해 질의 격차가 컸다. 대체할 타 플랫폼이 존재하는 업로드/다운로드 기능과 교육적 목적과 거리가 있는 예약하기, 전화걸기 기능들은 활용가치가 낮았다. 웹엑스는 전체적인 노후 된 UI가, 줌은 일방적인 음소거 기능이 원치 않는 기능으로 조사되었다. 그리고 이러한 결과를 분석해서 도출한 결론으로 개발 방향성을 다섯 가지로 제시하였다. 코로나-19에 따른 장기적인 교육 운영 방식을 고민해야 하는 상황에서 본 연구가 이러한 화상미팅 서비스가 교육용으로 개발되는 발판이 되도록 지속적인 연구로 이어져야 할 것이다.
