This study was carried out to P University of Education 111 students who participated in science materials study course 1 in spring semester 2011. Students have taken the course pre-service teachers of elementary school classes to target elementary school earth science field, they selected one of the sections to create a class and the students have fulfilled 15-minute classes in respectively from the first week of May 2011 to until end of that course. In this class, colleagues evaluated the classes and we used evaluated scores to determine level of instructional motivation strategy. The obtained results from this study are as follows; First, motivational strategies used by preliminary elementary school teacher were questions, presentation of pictures and photographs, storytelling, presentation of contradictory concepts and phenomena, pilot experiments Second, among preliminary elementary teachers' motivational strategies for teaching in the field of the earth storytelling, presenting contradictory phenomena and concepts, pilot experiment, presentation of contradictory concepts, questions got higher scores in the order. Third, storytelling received the highest scores by the evaluators. So we can consider storytelling as a good strategy for the next class. In particular, storytelling used by animism were more effective. Fourth, preliminary elementary school teachers used life knowledges and dairy experiences as instructional motivation.

주문형 교육 시스템(EOD)에서 스케쥴링 기법은 시스템의 효율을 높이고, 한번의 디스크 검색으로 여러 학습자들의 요구를 만족시키도록 설계되어야 한다. 이에 본 논문에서는 학습자 시스템의 자원을 활용함으로 서버의 디스크 입출력과 버퍼 소비를 줄이는 스케쥴링 기법을 제안하였다. 본 논문에서 제안한 스케쥴링 기법은 모든 서비스를 서버가 제공하는 것이 아니라 해당 자료를 저장하고 있는 학습자 시스템으로 하여금 서비스하도록 한다. 그럼으로써 학습자들의 초기지연시간 단축을 가져오고 서버의 처리량이 증가하게 된다. 본 논문에서 제안한 기법과 기존의 기법의 성능을 시뮬레이션으로 비교한 결과 제안한 기법이 효율적인 성능을 나타냈다.

The optimal price strategy selection of two bounded rational cognitive mobile virtual network operators (MVNOs) in a duopoly spectrum sharing market is investigated. The bounded rational operators dynamically compete to sell the leased spectrum to secondary users in order to maximize their profits. Meanwhile, the secondary users' heterogeneous preferences to rate and price are taken into consideration. The evolutionary game theory (EGT) is employed to model the dynamic price strategy selection of the MVNOs taking into account the response of the secondary users. The behavior dynamics and the evolutionary stable strategy (ESS) of the operators are derived via replicated dynamics. Furthermore, a reward and punishment mechanism is developed to optimize the performance of the operators. Numerical results show that the proposed evolutionary algorithm is convergent to the ESS, and the incentive mechanism increases the profits of the operators. It may provide some insight about the optimal price strategy selection for MVNOs in the next generation cognitive wireless networks.

본 연구는 Davydov가 언급한 이론적 일반화가 구체적으로 어떻게 이루어지는지를 탐구하는 것을 목적으로 하며, 이를 위해 본질적 속성의 인식을 돕는 전략과, 이 전략을 통해 이루어지는 이론적 일반화의 과정을 제시하는 것을 연구문제로 설정하였다. 본질적 속성의 인식을 돕는 전략으로 WIOS를 제시하였다. WIOS는 일반화하려는 명제의 결론을 고정하여, 명제의 가정으로부터 추출한 여러 속성을 대상으로 WIO를 통해 결론에 영향을 미치는 속성과 그렇지 않는 속성의 인지를 통해 본질을 추출하는 전략이다. 한편, 이 전략을 통해 이루어지는 이론적 일반화의 과정을 '인지, WIOS, 일반화된 명제의 추측, 정당화, 본질적 속성에 대한 통찰'의 순으로 제시하였다. 그리고 WIOS를 통해 이루어지는 이론적 일반화의 과정을 중학교 교과서에 수록된 2가지 정리에 적용하여 보았으며, 이를 통해 이 전략의 과정이 이론적 일반화의 수행을 도울 수 있는 전략임을 확인해 보았다.

The purpose of this study is to develop a science writing teaching strategy, and to apply it to the fourth-graders in elementary science classes. We examined its effect on their motivation, attitude, and understanding of science concept. For the research fourth grade children were grouped into three classes: an experimental class A of 27 children, an experimental class B of 24 and a comparative class of 27. All of them are from H elementary school in Seoul, Korea. Experimental class A learned science writing with a newly developed strategy while experimental class B learned science writing in a traditional method. Comparative class did not learn science writing. As a result, class A showed positive changes on students' science motivation, attitude, and understanding of science concept. In addition, class B with even one science writing task for a chapter had higher achievement in the understanding of science concept than the comparative class had.

The purpose of this study was to identify the necessity of research for increasing French language learners and to examine their use of listening strategies according to their proficiency as a basic study for their continuous learning and communication skills. In the case of French language Korean learners, both the beginner and intermediate learners used the upper cognitive strategy most frequently. However, the cognitive strategy, which has been mentioned as a frequently used strategy in previous studies, was found to be the least used in this study. This finding can be attributed to differences in mores and mastery of prior studies and research subjects. The cognitive strategy was lower in both the beginner and intermediate levels, but the level of use increased significantly in the intermediate level compared to the beginner level, showing only statistically significant differences in the usage patterns according to the proficiency level among the four listening strategies.
