최근에 성능의 한계를 드러내고 있는 수퍼스칼라 RISC를 대체할 새로운 프로세서 구조로서 SMT(Simultaneous Multi-Threading)이 활발히 연구되고 있다. SMT는 하나의 프로세서에 여러 개의 스레드가 하드웨어 자원을 동적으로 공유하며 동시에 수행되는 구조이다. 이러한 환경에서는 프로세서 안에 존재하는 여러 스레드로부터 명령어를 원활하게 공급하여 주는 것이 중요하다. SMT 프로세서는 기존의 프로세서에 비하여 사이클 당 실제 처리되는 명령어 수가 월등히 많기 때문에, 사이클 당 명령어 페치량과 페치된 명령어를 임시 저장하는 페치 큐의 엔트리수가 신중하게 결정되어야 한다. 또한 사이클마다 페치할 스레드와 각 스레드의 페치량을 결정하는 것이 성능에 큰 영향을 미친다. 따라서 본 논문에서는 이러한 요소들이 프로세서 전체의 성능에 미치는 영향을 분석하고 그 결과를 바탕으로 SMT 프로세서에 최적화된 명령어 페치 전략에 대하여 논한다.

In the teacher's guide of mathematics textbook for the 1st grade of the middle school, the clear and logical reason why the multiplication of negative number to negative number makes positive number, and $a^{-m}$ with a>0 and m>0, is defined by ${\frac{1}{a^m}}$ is not given. When we define the multiplication or the power by successive addition or successive multiplication of the same number, respectively, we encounter this ambiguity, in the case that the number of successive operations is negative, In this paper, we name this number, negative counting number, and we make the following more logical and intuitive definition, which is "negatively many successive operations is defined by positively many successive inverse operations." According to this new definition, we define the multiplication by the successive addition or the successive subtraction of the same number, when the multiplier is positive or negative respectively, and the power by the successive multiplication or the power is positive or negative, respectively. In addition, using this new definition and following the E.R.S Instruction strategy which revised and complemented the Bruner's E.I.S Instruction strategy, we develope new teaching model available in the 1st grade class of middle school where the concept of integers, three operations of integers are introduced.ntroduced.

This study examines how teaching metacognitive strategies to students in a sixth-grade mathematics class affects their metacognitive awareness. Participants were 36 sixth-grade students in a middle school affiliated with the Ministry of National Education of Turkey in the 2020-2021 academic year. The students in the experimental group (n = 18) were taught a total of 40 mathematics lessons for eight weeks to improve their metacognitive awareness. The students in the control group (n=18) were taught mathematics in line with the regular mathematics curriculum. Using the Jr. Metacognitive Awareness Inventory, participants in both groups took a pre-test at the beginning and a post-test at the end of the study. To better interpret the data obtained, various statistical tests were performed. The pre-test and post-test averages of the groups were compared using the t-test for the normally distributed data for dependent and independent groups. The pre-test results showed no significant difference between the metacognitive awareness scores of the experimental and control groups (p>0.05). The comparison of post-test averages showed that students' metacognitive awareness differed significantly in favor of the experimental group (p<0.05). According to this, it was concluded that metacognitive strategy teaching in mathematics courses positively affected students' metacognitive awareness levels.

The purpose of this research is to improve the writing ability of students by an ideal test model of English writing based on strategies of procedural learning stages enhancing the level of students' writing ability. Assessment of writing in the field of English education has been limited so far to very restricted areas with no appropriate scientific scrutiny. Assessment is really meaningful only when it exactly estimates the ability of students. Since English writing competence has become indispensable in this era of global village, writing instruction should be most emphasized. The most forceful method of busting writing instruction is to utilize the so-called washback effect of testing. So, to develop a good test model of writing, the first thing that is required is to inspect writing strategy in steps and, then, testing itself. First of all, analyzed with a special reference to the 6th high school English curriculum were the goals and contents of the syllabus reflected in one kind of junior high textbook and eight different kinds of senior high textbooks. Then questionnaires on the whole area of writing and tendencies of English writing classes were given to 100 English teachers, 300 students. The results of questionnaires were statistically analyzed. Then, some suggestions and opinions about the questioning method were made: the procedural strategy in steps, English writing instruction and test model of assessment were applied to the syllabus referring to teaching plans. On the bases of the results of the questionnaires, three pretests and a final test of English writing were administered to verify the effect of enhanced English writing competence which had been gradually promoted and, through the promotion, produced the test criteria of English writing. In conclusion, guidance and evaluation of English writing through in steps are really indispensable to increase student's practical ability and, accordingly, we are in need of the development of a testing method of useful writing practiced in school class above anything else. So, it is necessary to further the study on methods to assess writing ability on the bases of participation and fluency of students with their keen interest in English. Also, to intensify the effect of the test model, more accommodating reorganization of syllabus is required in our education. For instance, we need a flexible operation in organizing time units from the current 50 minutes to 100-130 minutes.

The purpose of this study was to develop and apply a differentiated instruction-learning reflecting various characteristics and demands of the gifted underachievers, and thereby help to develop the study attitude and study achievement of the gifted underachievers. To achieve the purpose, a case study on five gifted underachievers who are in $6^{th}$ grade of elementary school was conducted. By collecting and analyzing a variety of data including standardized tests, interviews with teachers, students, and parents, and observation journals, this researcher examined the characteristics and demands of the gifted underachievers. For the development of the program, differentiated strategies were designed according to students' interest and concern, their multiple-intelligence, and their learning styles. As a result of the application of them, a program with a total of 20 sections was finally developed. The result of the application for the differentiated instruction-learning program revealed improvements in their academic achievements. In addition, it was found that their learning motives were improved. The program was also found to affect their self-concept and their attitude toward learning. The study showed that developing an education program for the gifted underachievers should begin from the analysis of each student's characteristics. Also, it was found that a differentiation strategy could become an alternative to apply various characteristics and demands of the gifted underachievers to the development of a program. The gifted underachievers' intellectual and definitive characteristics were changed even by the short-term mediation. Therefore, the new issue about educating the gifted is to provide a differentiated instruction-learning program fitting their characteristics and demands and help them exert their potential as best as they could.

본 연구는 교사와 학생의 가치의 변화 양상을 분석하기 위해 수학학습 가치 설문지를 활용하여 15차시 수업이 진행되는 과정에서 학생들과 교사의 가치를 4차에 걸쳐 분석하였다. 그 결과 가치는 개인이 수많은 경험을 거쳐 내면화된 깊이 있는 판단 양식임에도 불구하고 수업이 진행됨에 따라 많은 변화가 나타났다. 교사는 자신이 중요하게 생각하는 가치를 무조건 강요하기 보다는 학생들이 무엇을 중요하게 생각하는지를 반영하여 자신의 목표를 수정해 나갔다. 수학적 가치의 경우, 합리주의, 객관주의, 미스터리는 교사와 학생이 서로 수렴하였고, 통제는 일관되게 유지되었으며, 개방의 경우 교사와 학생모두 상향 하였다. 수학 교육적 가치의 경우에는 이해, 즐거움, 용어, 적용의 경우 서로 수렴하였고, 성취는 일관되게 유지되었다. 또한 교사는 효과적인 수업으로 나아가기 위해 끊임없이 학생과의 가치에 대해 협상해 가면서 몇 가지 전략을 사용했다. 이러한 연구 결과를 바탕으로 진정한 의미에서 학습자 중심수업으로 나아가기 위한 한 가지 방안으로 가치가 중요한 요인이 될 수 있다는 시사점을 제공하고자 하였다.

The purpose of this study is to investigate the effects of peer-to-peer relay feedback strategy on achievement in mathematical problem solving and mathematical communication ability. The experimental instruction was given to 99 students. They were divided into two groups. In this research a strategy of peer-to-peer relay feedback is developed. To enhance lateral communication, students were instructed according to the strategy to read open-type problems, to write mathematical ideas individually and to share their ideas and get feedback in relay method with peers within a small subgroup. The results are as follows. 1) Mathematics achievement assessments were carried six times in the cleanup phases of the class. There was no difference at the 1st test. 2) The second t-test of mathematical communication abilities showed that there was meaningful difference and that peer-to-peer relay feedback was effective. But there was no difference on reading. 3) Peer-to-peer relay feedback strategy has a positive impact.
