The purpose of this study is to analyze the structural relationship among the usefulness, ease of use, use intention, and learning utilization of smart learning devices recognized by college students. In order to achieve this, the following problems were addressed: first, how do college students' recognition of ease and usefulness of smart learning devices? second, how do college students' recognition of ease and learning utilization? third, what mediating effects od use of smart learning devices and learning utilization? As for the research method, a survey of 350 students who participated in smart learning was conducted to conduct a home review, confirmatory factor analysis, and bootsrapping for structural equation estimation and mediating analysis. As a result of the analysis on this, first, it was found that the usefulness and ease of smart learning devices recognized by college students had an effect on the intention of use. Second, it was found that the perception of the usefulness and ease of smart devices perceived by college students had an effect on the use of smart learning device learning. Third, it was found that the intention to use smart devices perceived by college students mediated the relationship between usefulness and learning utilization, and it was found that it mediated the relationship between ease and learning utilization. The implications are that instructors can recognize and utilize the intention of using smart learning devices properly by allowing college students to recognize the usefulness and ease of using smart learning devices in the classroom, thereby increasing the learning utilization of smart learning devices in class. In addition, efforts are needed to enable college students to recognize the usefulness of smart devices and to expand the use of learning.

The purpose of this study is to examine difference of information processing style on lesson comprehension scores and usability ratings in e-Learning containing visual information structure. To address this goal, 68 university students were participated in this research. They were asked information processing style test, lesson comprehension test, and usability ratings after completed e-Learning lesson. According to the result, there was not significant difference between visual and verbal information process style on lesson comprehension as learn outcomes. However, students who are visual information processing style were significantly higher ratings than students who are verbal information processing style on 4 of 8 usability scales; awareness of lesson structure, awareness of lesson length, ease of navigation, and ease of lesson learning. These result indicate that there will be needed the design of aptitude treatment interaction for e-Book according to information processing style.

This study delineates the process of analyzing the illustrations in high school English I textbook. The goal of this study is to shed light on the issues related to producing better English textbooks. The methods include analysis of the illustrations in the textbook developed under the 2009 Revised National Curriculum and surveys of teachers and students' awareness about them. This study classified common features in the illustrations to devise four analysis criteria: cultural aspects, expression styles, expression techniques, and linguistic functions of the illustrations. The questionnaire was made for both teachers and students. The questions in the survey of teachers were about the relevance to the contents, the layout and formation, learners' interest, cognitive aspects, easiness of teaching and learning, and connectivity with language functions. In the survey of students, familiarity, interest level, learnability, favored expression technique and expression material were considered. The result of the surveys showed that the teachability and learnability are key factors in developing illustrations for English textbooks, and they should look familiar to the students.

The purpose of this study is finding factors affecting the students' use of the Cyber Home Learning Service System and exploring the direction of this system. It is based on the TAM(Technology Acceptance Model) and the result of the previous studies, six external and three internal factors influencing the sue of Cyber Home Learning Service System were extracted. The participants were 201 elementary school students in Pusan. The response of the questionnaire was gathered by online survey system. To analyze the data and the hypothesis, multiple regression and factor analysis were explored. The result indicated that (a) "usefulness" and "future-intention" affected statically to the use, (b) "usefulness" to the future-intention, (c) "subjective judgement", "fun", and "ease of use" to the usefulness, (d) "self-efficiency" and "contents quality" to the ease of use.

본 논문에서는 SVM의 학습성 개선을 위해 모멘트와 kernel-adatron 기법이 조합된 하이브리드 학습알고리즘을 제안하였다. 제안된 학습알고리즘은 SVM의 학습기법인 기울기상승법에서 발생하는 최적해로의 수렴에 따른 발진을 억제하여 그 수렴속도를 좀 더 개선시키는 모멘트의 장점과 비선형 특징공간에서의 동작과 구현의 용이성을 가진 kernel-adatron 알고리즘의 장점을 그대로 살리는 것이다. 제안된 알고리즘을 비선형 함수 회귀에 적용해 본 결과 학습속도에 있어서 QP와 기존의 kernel-adatron 알고리즘보다 더 우수한 성능이 있음을 확인하였다

The purpose of this study is to investigate the change of students' perceptions by comparing factors affecting e-learning intention before and after e-learning experience based on longitudinal data. For this purpose, a research study was conducted targeting university students at Y and K universities in Gyeongsangbuk-do. As a result, first, the convenience of learning time, the ease of learning process, and the usefulness of e-learning had an effect on e-learning intention regardless of the learning experience. Second, the convenience of the learning space was different in the perception before and after the learning experience, and it was found to affect the intention to use after the e-learning experience. Third, college students who have experienced e-learning have shown that the ease of learning process has the most influence on their intention to use. The results of this study can provide an effective direction of e-learning activation and provide basic data for longitudinal research on e-learning learners.

본 연구는 정보기술의 사용(Usage)과 수용(Adoption)을 예상하는 목적보다는 웹 기반 협동합습 시스템사용 의도와 사용행위에 영향을 미치는 변수들을 폭 넓게 이해하고, 실질적으로 활용 할 수 있는 변수를 찾는데 목적이 있기 때문에 분해된 계획 행동 이론(Decomposed TPB)을 기반 하였고, 분해된 변수들 중 일부분(지각된 유용성, 지각된 용이성, 명시적 영향, 암시적 영향)과 웹 환경의 중요 요소인 '흥미성' 을 포함하여 사용의도(Use Intention)에 영향을 미치는 변수들을 2개 대학의 대학생 256명을 대상으로 자료를 수집하여 실증 분석하였다. 연구결과 다차원으로 분해된 일부 변수들 중 태도적 믿음 변수인 '지각된 용이성'을 제외하고 분해된 모든 변수가 사용의도에 긍정적 강한 영향을 미치고 있음을 알 수 있었고, 특히 주관적 규범(명시적 영향, 암시적 영향)변수는 준거집단을 통해서 웹기반 협동학습 시스템에 대한 행동의도나 인지에 영향을 줄 수 있는 중요 변수로 나타났다. 이러한 결과는 준거인이 되는 팀장은 팀원 및 학습자들과의 상호작용(협동학습을 통한 화상토론, 게시판정활동, 오프라인 정기 모임, 동영상 동시 시청)과 팀원 관리 및 운영하는 역할이기 때문에 새로운 정보 기술 및 시스템 사용 권유를 하거나, 직접 기술사용을 하는 주변 분위기는 협동합습에 참여한 학습자들에게 조금이나마 영향을 줄 수 있음을 추측 해 볼 수 있고 영향력 있는 중요변수임을 제시하였다.
