The purpose of this study is to analyze the relationship between home economics curriculum and media literacy education. For this purpose, 12 kinds = types of learning materials for middle school 'Technology·Home Economics 2' textbooks were analyzed. After selecting 'Media Literacy Performance Goals(MLPG)' as the basis for analysis, the distribution of media data and reflection of MLPG were analyzed by frequency and content analysis. The results of this study are as follows. First, 39.6% of the learning materials using media materials out of the total learning materials of 12 textbooks, and there were differences in the frequency and weight of learning materials using media materials by publishers. Depending on the type of media, 68.3% of 'printing', 16.7% of 'images, video', 13.5% of 'digital', and 86.5% of the use of unidirectional media. Second, there was a difference in frequency and weight of learning materials reflecting the MLPG by publishers, and it was necessary to supplement the learning content to improve overall media literacy. Among the MLPG reflected in the learning materials, 'meaning and communication' was the most reflected performance goal, with 58.8%, but there was no two-way communication through the media. Based on the results of these textbook analysis, MLPG in Home Economics are revised as follows. 'Understanding the meaning and self-expression', 'Communication and social participation', 'Use of responsible media', 'Appreciation and enjoyment', 'Use of media technology', 'Information search and selection', 'Creation and production', 'Critical understanding and evaluation'.

The purpose of this study is to investigate the level of awareness and current performance level of self-directed learning (SDL) in nursing students. The core concepts were defined and a rubric was developed through literature review. It was applied later to subjects and the results were analyzed. According to the results, there were significant differences between the current performance level and the awareness level of SDL in all items. Students who chose nursing as a major due to their high school/SAT grades showed lower current performance level than others. There were insignificant differences in the current performance level influencing the next grade. The level of awareness showed insignificant differences according to the reason for selecting nursing as a major, satisfaction on major, and grade point average (GPA). In conclusion, there was a discrepancy between the level of awareness and the current performance level of SDL of nursing students, which indicates that they were aware of the necessity of SDL, but did not actually perform it. Nursing educators should seek for strategies that can improve SDL ability of their students as well as to better grasp the level of the SDL of their student and the current performance level of SDL to apply them to the instructional design.

A three factor experiment was conducted to explore the effects of giving prompts and asking for self explanation and the modulating effect of the need for cognition (NC) on the two interventions. The effects of giving prompts and asking for self explanation were different depending on the task and the level of need for cognition. Participants of low NC conditions showed the prompt effect and the self explanation effect in the memory tests. On the other hand, participants in the high NC conditions performed better in the comprehension test when they were given prompts and were asked to self explain. However, high NC participants performed worse when they were asked to self explain without providing the prompts. The results were interpreted to suggest the importance of detecting the right parts in getting the self explanation effect.

인간의 사고 기능과 학습기능이 '뇌'를 바탕으로 이루어진다고 할 때, 뇌의 긴장을 풀어 원래의 건강하고 창조적인 이완 상태에서의 학습 상태가 유효하게 된다. 즉, 뇌파가 " $\alpha$" 상태 가 되었을 때 긴장된 신체의 각 부분이 충분히 이완되고 두뇌는 맑고 건강한 상태를 유지하여 활발하고 창조적인 상태가 된다. 뇌파의 측정 및 분석된 기존 연구에 의하면, 인간의 심리상태와 신체 상태, 행동 패턴에도 직, 간접적인 영향을 주어 뇌파의 조절이 인간 잠재능력 개발의 첩경이라는 결과가 보고되어진다. 이러한 관점에서 본 연구에서는 뇌의 특성을 고려하여 뇌를 이완시킴으로써 학생들의 학습능력을 향상시키 기 위한 새로운 접근 방법을 시도한다. 뇌파 조절이 가해지는 환경하에 학습 효율의 변화 정도를 정성적( 심리적, 학습적, 신체적) 및 정량적(영어 단어 암기력 TEST, 뇌파 특정 등)으로 평가 및 분석을 통해 뇌파 조절 효과가 학생들의 학습 효율을 더욱 향상 시킬 수 있는 지의 타당성을 검증하고 그 결과를 바탕으로 새로운 학습 방법을 모색하고자 한다. 한편, 본 연구에서는 실험 대상을 본 대학 임의의 2학년 학생 13 명 을 대상으로 하고 실험기간은 약 4개월에 걸쳐 실험 하였다. 뇌파 측정은 13명중 임의의 학생 7명을 선정 하여 각 40분씩 측정 분석하였다. 또한 영어 단어 암기력 TEST를 실시하여 그 결과를 뇌파 조절 전,후로 나누어 비교 분석하였다. 정성적 분석으로서 종합 설문지를 이용한 15 개 항목의 5점 척도를 사용하여 분석하였으며 가가 통계 이론을 이용하여 검증하였다. 뇌파 측정은 수행 전후 비교 결과 " .alpha. " 노출 비율이 수행 전보다 수행 후가 다소 높은 비유로 나타났으며, 특히 영어 단어 암기력은 평균적으로 크게 상승되는 것으로 나타났다. 정성적 분석 결과에서는 많은 심리적 변화 상태가 나타나고 있지만 전체적으로 마음의 안정감, 몸의 긴장 이완에 따른 건강 상태 유지, 수업 집중도 향상 등이 나타났다. 위와 같은 종합 적 분석 결과에 따라, 본 연구는 제조 현장의 생산성 향상 및 품질 향상과 연계하여 작업자의 작업 집중도 향상, 작업자의 육체적, 심리적 변화에 따른 생산성 및 품질 향상 변화 정도 등의 산업공학(인간공학) 제 분야의 여러 측면에서 연구 및 적용이 가능하리라 사료된다.

Recently, various methods of text embedding using deep learning algorithms have been proposed. Especially, the way of using pre-trained language model which uses tremendous amount of text data in training is mainly applied for embedding new text data. However, traditional pre-trained language model has some limitations that it is hard to understand unique context of new text data when the text has too many tokens. In this paper, we propose self-supervised learning-based fine tuning method for pre-trained language model to infer vectors of long-text. Also, we applied our method to news articles and classified them into categories and compared classification accuracy with traditional models. As a result, it was confirmed that the vector generated by the proposed model more accurately expresses the inherent characteristics of the document than the vectors generated by the traditional models.

This paper proposes a Distributed Autonomous Robotic System(AIS) based on Artificial Immune System(AIS) and Distributed Genetic Algorithm(DGA). The behaviors of robots in the system are divided into global behaviors and local behaviors. The global behaviors are actions to search tasks in environment. These actions are composed of two types: dispersion and aggregation. AIS decides one among above two actions, which robot should select and act on in the global. The local behaviors are actions to execute searched tasks. The robots learn the cooperative actions in these behaviors by the DGA in the local. The proposed system is more adaptive than the existing system at the viewpoint that the robots learn and adapt the changing of tasks.
