This study aims to investigate the relationship between various motivational factors and to identify other causative components affecting English learners' learning motivation(From March to Jun, 2012). In case of integrative motivation and instrumental motivation, there was a statistically significant difference among those who have studied in other countries. However, in the case of negative motivation, there was a statistically significant difference among those who have no learning experience in other countries. English learners' learning motivation between the students majoring in Liberal Arts and Others, learning contents and teaching methods were significant factors.

This study aimed to investigate the effects of science learning motivation and science self-efficacy on the science learning flow of preservice elementary teachers. The study recruited 77 preservice elementary teachers during their sophomore year from the B university of education. Descriptive statistics, correlation coefficient, and multiple regression were used for data analysis. The results were as follows: science learning motivation and science self-efficacy exerted a significant positive correlation with and a statistically significant effect on science learning flow. Satisfaction was the main influential subelement of science learning motivation. For science self-efficacy, the main influential subelements were emotional stability and language encouragement. Moreover, it was deduced that self-efficacy exerted a greater effect on science learning flow than science learning motivation.

학습에 동기부여를 위한 도전들이 있는 상황을 증진시키는데 효과적이고 도움이 되는 정보에는 어떠한 종류들이 있는지 조사되고 있다. 특히 Keller(1998)의 동기유발 요소 중에서도 학습자들의 요구나 흥미, 학습할 내용과의 관련성을 제시하는 것이 학습 동기와 학업성취를 높인다고 밝히고 있다. 그러나 이런 동기유발 요소만으로 학업성취가 높아지는 과정을 모두 설명하기는 부족하다. 웹기반 학습에서는 학습에 대한 의지를 지속시키지 않으면 학습자들이 학습에 대한 인지적 과부하와 방향상실을 경험하게 되어 오히려 학습의 효과가 떨어지게 된다. 이러한 관련성과 학습 의지적 요소에 관한 선행연구들을 바탕으로 웹 기반 학습에서 관련성과 학습 의지 요소 전략의 사용이 학습 동기 및 학업성취에 미치는 영향을 밝히고자 한다.

Motivation is a generative power of making learning interesting and sustaining learning for students. Textbooks are important tools in carrying out lessons. And it is meaningful to analyze how textbooks motivate learning. This study is to analyze components of motivation in learning of the 7th grade middle school science textbooks. Keller's ARCS model was used for the analysis. The result of the study is as follows. First, the eight textbooks had various components from A1 to R3. Second, analyzing textbooks by parts of the textbooks, the body had the most motivation strategies and the next was the introduction, lastly the finishing part. Third, the most frequently used strategy on the attention factor is A1. And the most frequently used strategy in the relevance factor is R3.

Time synchronization is a prerequisite in wireless sensor network applications such as object tracking, consistent state update, duplication detection, and temporal order delivery. This paper analyze time synchronization accuracy of pair-wise time synchronization algorithm which is a typical time synchronization model of time synchronization method in wireless sensor networks. In addition, the analyzed results are verified by simulations. These results can be utilized for performance improvement or development of time synchronization in wireless sensor networks.

The purpose of this study was to identify the effects of the health leader education on health behavior motivation, perceived health status, knowledge improvement, and life satisfaction among the living in rural area. The subjects consisted of 50 health leaders who participated in the health leader education program. Pre-and post-education tests were collected after education. The data were analyzed using the SPSS 22.0 program with frequency, means, ANOVA, Paired t-test. The data significant changes in motivation, perceived health status, knowledge improvement. The data not significant changes in life satisfaction. Based on this study, a continuous health leader education program through a community health center is needed for rural community people.

This paper proposes three methods of the time synchronization for Pseudolite and GPS and analyzes pseudolite time synchronization error factors for software based performance evaluation on proposed time synchronization methods. Proposed three time synchronization methods are pseudolite time synchronization station construction method, method by using UTC(KRIS) clock source and GPS timing receiver based time synchronization method. Also, we analyze pseudolite time synchronization error factors such as errors of pseudolite clock and reference clock, time delay as clock transmission line, measurement error of time interval counter and error as clock synchronization algorithm to design simulation platform for performance evaluation of pseudolite time synchronization.

This study analyzes MMORPG in user's desire perspective and tried to find specific motivation factors. In research result, character has been separated in user character, another user character, boss monster and support character. And character's factor analysis yielded three factors: visual attraction, psychological propensity and competence. The result of the regression analysis about character's motivation factor show that it is significantly different that motivation level and motivation factors from each character. This finding implies that specific motivation factors can serve to make strategy for motivate user's game playing.

종단간 전송 지연은 시각 동기, 네트워크 성능 측정 등에서 매우 중요한 요소이다. 그러나 IP에 기반하고 있는 Internet은 여러 통신망 상의 지연 요소를 정확히 전달할 수 있는 구조가 없기 때문에 종단간 전송에 있어 전송 지연을 정확하게 알 수 없다. 특히 UDP 네트워크의 경우 전송할 때와 수신할 때 경로가 같지 않기 때문에 일반적으로 일주 지연 시간을 이용하지만 각 편도 전송 지연 시간 차이는 시스템의 다른 요소에 대해서 오류 요소로 작용할 수 있다. 본 논문에서는 일주 지연 시간을 전송시 지연 시간과 수신시 지연 시간으로 따로 측정 분석하였다. 측정 결과 편도 전송 지연 시간 차이 값은 수십 밀리초 범위를 가지며 이는 NTP 등에서 시각을 동기화 할 때 통상적인 정확도, 수 밀리초를 훨씬 넘어선다. 이것은 편도 지연 시간 차이값이 시각 동기, 네트워크 성능 평가 등에서 중요한 오류값으로 작용한다는 것을 의미한다. 분석 결과를 실험 데이터에 적용할 경우 실제 편도 지연 시간에 근사한 값을 구할 수 있고 좀더 정확한 시각 동기, 네트워크 성능 평가가 가능하게 된다.
