미래 사회의 변화에 대비하기 위해 범교과 학습이 강조되며, 범교과 학습 주제와 교과를 연계할 필요성이 증가하고 있다. 그러나 수학과에서 범교과 학습을 어떻게 다뤄야 하는지에 관한 연구는 거의 없다. 본 연구에서는 교과별 교육 과정과 수학과 교과서에 적용된 범교과 학습 주제의 내용과 방법을 문헌 분석하였다. 연구 결과 교과별 교육과정을 적용된 범교과 학습 주제의 다양성, 주된 범교과 학습 주제의 유무에 따라 총 4가지 유형으로 구분할 수 있었고 이 때 수학과 교육과정은 일부 범교과 학습 주제가 소극적으로 다뤄지고 주된 주제가 없는 유형에 속하였다. 한편, 2015 개정 교육과정에 따른 5~6학년군 수학 교과서 10종을 분석한 결과, 교육과정과 달리 교과서에는 다양한 범교과 학습주제가 적용되어 있었고 이중 환경·지속가능발전 교육, 안전·건강 교육, 진로 교육, 인성 교육, 경제·금융 교육 순으로 주를 이뤘다. 또한 수학 교과서에는 범교과 학습 주제가 소재, 발문, 설명, 자료, 삽화와 같이 다양한 유형으로 반영되어 있었는데, 주로 소재나 삽화로 나타난 경우가 많았다. 그리고 수학 교과서에는 범교과 학습 주제가 주로 도입 차시, 본 차시의 도입 활동, 특화 차시에 반영되어 있었다. 이런 결과를 바탕으로 수학과에 범교과 학습 주제를 연계하는 방안을 모색하고 제시하였다.

This study analyses the cross-application system, one of the diversified college admission processes, based on the entrance examination system by the reorganization of the education curriculum. In addition, this study suggests an improvement direction of mathematics education for students who cross-apply by comparing and analysing academic results in Calculus for those students entering universities through the cross-application system.

The purpose of this study is to analyze the setting and directions of cross-curricular learning topics based on research on experts' recognition of cross-curricular learning topics. The study method adopted was Delphi, and the subjects selected were curricular experts. This study has drawn following results: first, regarding the essence and problems of cross-curricular learning topics, even among the experts, there is no opinion agreed about cross-curricular learning topics' concept, essence, or characters. Second, more detailed discussion is demanded to select cross-curricular learning topics and set up a guideline about the operation. Third, it is needed to examine closely if presently suggested cross-curricular learning topics are duplicated or not and consider related subjects connected with those cross-curricular learning topics to improve education more systematically. Fourth, it is necessary to conduct more profound and systematic research on core competence that can embrace those cross-curricular learning topics. Fifth, to cope with changes in society and demands at school, it is needed to discuss how cross-curricular learning topics should be added or which learning topics should be added.

The purpose of the present study is to develop several types of English teaching/learning models in view of cross-curricular approach in Korean elementary school. Brewster(1992)' model is suitable for younger children as well as the 1st or 2nd graders. For 3rd or 4th graders, Halliwel1(1997)' model seems more proper type in Korean EFL situation. There has been studying for cross-curricular approach in elementary English education. Many studies has recently focused the characteristics of elementary students by cognitive and psychological perspectives. Among them, Park(1996)'s research talks about the elementary school students. Han(1996)'s research based on the notion of applied to other subjects. Kim(1999)'s also emphasized the importance of linking other subjects. Kim(2003) argued the need of integrating English with other subjects. The elementary education as the National Common Basic Curriculum(NCBC) has the essence of cross-curricular approach, so the English education will be linked with other subject matters more and more, not just as for Communicative function based English education but as both content and function based subject matter.

Purpose: We investigated the effects of physical practice, mental practice, and cross education using serial reaction time (SRT). We recruited 21 right-handed healthy males and females who gave consent and had no clinical history for their upper limbs. Methods: The subjects were divided into three groups; actual practice (n=7), mental practice (n=7), and controls (n=7), who performed actual training, mental training, or no intervention respectively for three weeks. Super lab 4.0 displayed four symbols on the monitor and subjects pushed on the matching button, with reaction time assessed pre- and post-intervention. Results: Reaction time was significantly lower after actual or mental practice (p<0.05). Actual practice also decreased left hand reaction time. Conclusion: Actual practice and mental practice can improve motor learning, but mental practice is not sufficient for cross education.

Tolerance education must be based on the fact that tolerance like democracy cannot be achieved once and for all. Students must learn to constantly watch political and cultural processes for negative developments. Tolerance for others' values and behaviour can be learnt by studying previous historiographical views. The basic attitude to be learnt is repect for other cultures - within one's own culture as well as foreign cultures.

In order to improve the measurement accuracy of the 6-dimensional accelerometer, the cross coupling compensation method of the accelerometer needs to be studied. In this paper, the non-linear error caused by cross coupling of piezoelectric six-dimensional accelerometer is compensated online. The cross coupling filter is obtained by analyzing the cross coupling principle of a piezoelectric six-dimensional accelerometer. Linear and non-linear fitting methods are designed. A two-level calibration hybrid compensation algorithm is proposed. An experimental prototype of a piezoelectric six-dimensional accelerometer is fabricated. Calibration and test experiments of accelerometer were carried out. The measured results show that the average non-linearity of the proposed algorithm is 2.2628% lower than that of the least square method, the solution time is 0.019382 seconds, and the proposed algorithm can realize the real-time measurement in six dimensions while improving the measurement accuracy. The proposed algorithm combines real-time and high precision. The research results provide theoretical and technical support for the calibration method and online compensation technology of the 6-dimensional accelerometer.

In the context of Korean educational research, the number of qualitative research studies has gradually increased since 2000. It has become one of the most important research methods today. The field of math education is no exception to this trend, and qualitative approaches are now becoming one of the main research methods. This increase in qualitative research has contributed to the provision of detailed information about educational practice, but at the same time, the overall level of credibility in the results of qualitative research seems to be lower than that of quantitative research. This study started with the problem consciousness that the number of qualitative studies is increasing in the field of mathematical education, but there is a lack of discussion on the methodology of applying qualitative research methods. In this study, among the papers published in the journal related to mathematical education, papers using a qualitative approach are analyzed focusing on cross-case analysis. Based on the analysis results, the tendency to use qualitative approaches is diagnosed, ways of improving the validity and trustworthiness of qualitative research results in the field of mathematical education are examined, and implications and suggestions are presented.

Owing to limited energy in wireless devices power saving is very critical to prolong the lifetime of the networks. In this regard, we designed a cross-layer optimization mechanism based on power control in which source node broadcasts a Route Request Packet (RREQ) containing information such as node id, image size, end to end bit error rate (BER) and residual battery energy to its neighbor nodes to initiate a multimedia session. Each intermediate node appends its remaining battery energy, link gain, node id and average noise power to the RREQ packet. Upon receiving the RREQ packets, the sink node finds node disjoint paths and calculates the optimal power vectors for each disjoint path using cross layer optimization algorithm. Sink based cross-layer maximal minimal residual energy (MMRE) algorithm finds the number of image packets that can be sent on each path and sends the Route Reply Packet (RREP) to the source on each disjoint path which contains the information such as optimal power vector, remaining battery energy vector and number of packets that can be sent on the path by the source. Simulation results indicate that considerable energy saving can be accomplished with the proposed cross layer power control algorithm.
