This paper introduces an instruction fetch unit which is designed for RAPTOR, an on-chip multiprocessor. In order to reduce control hazards, the proposed fetch unit supports a hybrid branch prediction scheme which consists of a static scheme and the 2bC branch prediction scheme. The fetch unit also utilizes the branch folding technique with two instruction buffers to avoid the branch penalty caused by imspredictions. Instructions are predecoded in the fetch unit to achieve extra performance gain.

In order to support various parallel computing systems, it is necessary to extend LLVM IR to more efficiently support vector / matrix and to design LLVM IR to machine code as a new algorithm. As shown in the IR example, RISC instruction generation is naturally generated because the RISC instruction is basically composed of the RISC instruction, and the vector instruction is also not supported. There is a need for new IR structures, command generation algorithms and related extensions to support vector / matrix more robustly. To do this, it is important to map each instruction in the LLVM IR to the appropriate instruction in the target architecture (vector / matrix) (instruction selection algorithm). It is necessary to understand the meaning of LLVM IR command, to compare the meaning of each instruction of the target architecture with syntax, and to select the instruction that matches the pattern to make mapping efficient.

Due to a lack of teachers and available classrooms, high school students are not able to take the elective courses of their choice. In order to solve this problem with online instruction, I have used the following methods: First, I conducted a literature study to examine the concepts and models of online instruction. Second, I compared the number of students who took the CSAT subject tests with the number of students who enrolled in optional courses through KEDI's Education Statistics Services. Using the data gathered from this comparison, I could predict the demand for each optional course. Finally, I proposed amending the Elementary and Secondary Education Act; the Enforcement Decree of the Elementary and Secondary Education Act; the General Statement Curriculum of High Schools; and the Guidelines for Recording School through the expert interviews for on-line instruction in order to establish online instruction for high school students.

The key feature of the $7^{th}$ Education curriculum, which is applied by order by year from 2000, is represented by differentiated curriculum. In order to embody differentiated curriculum, it is extensively recommended the level-based instruction. Level-based class basically has purposes to give students matched study experiences in accordance with their abilities and to help all students to understand what they have learned through providing differentiated instruction with considering the learners' stand points. The preceding researches have reported many cases about operating methods and educational effectiveness for the level-based instruction. In the meantime, researches about students' acceptances or opinions related to the level-based instruction are not sufficient. In this research, students opinions about level-based instruction are analyzed, based on the distinction of sex and level, and improving operational methods are suggested.

The purpose of this paper is to examine the effectiveness of presentation-based instruction and to suggest a model of instruction targeted to the Korean intermediate level students learning English as a foreign language (EFL). To achieve this objective, the author examined how the acquisition of practical English through oral presentation would enhance the students' learning motivation, language abilities, and communicative competence in concrete situations. It was confirmed that the trained leader and systematic teaching and learning are needed to maximize the effects of presentation-based instruction. In doing so, the author compared and analyzed the collected data in order to support the validity of this teaching method. It was further pointed out that the teacher should have a close look at the roles of the presenter and learner in an effort to work out the usefulness of such an instruction model. The method of presentation in classroom settings would be a practical mode to attain the essential purpose of EFL teaching particularly to get over the drawbacks of Korean students' communicative competence. As a result, it would be an effective teaching method to meet the nation's long-standing demands for EFL education.

The research objective was to identify the effect of various instruction media on improving students' foodservice management competencies and for increasing class satisfaction. The research involved a comparison of two student groups. One group consisted of students who attended a lecture-based food purchasing class (Group A). The other group was students who attended the same class, and who also used various media as well as receiving the lecture (Group B). The results were as follows: 1) After a 16 week program, Group B perceived their procurement management competencies to be higher than those of Group A, especially in setting up purchasing goals, marketing research, and using computer systems for procurement; 2) In terms of class satisfaction, it was also observed that Group B was more satisfied with food purchasing class than was Group A. Group B gave high scores, especially in effective utilization of media, increasing motivation, and understanding; 3) Group B perceived that various instruction media was helpful for developing their procurement management competencies. Respondents evaluated the usefulness of media in the following order: using Power Point watching videos, visiting web-sites for food purchasing class, and surfing the World Wide Web. The results of the research show that using various instruction media for food purchasing classes would improve students' foodservice management competencies. Therefore, instructors who teach foodservice management related courses should consider developing teaching strategies that apply various instruction media for students to enhance their foodservice management competencies and to increase class satisfaction.

This study is to establish the items on class critiques based on the mathematical competencies according to the mathematics curriculum revised in 2015. Namely, this study deals with the items on how pre-service or in-service teachers understand and comment on mathematics instruction on their own instruction or peers' instruction. To accomplish this, first of all the draft items on instructional reviews was developed by researchers of this study on the basis of the previous study(Hwang, 2018). In order to revise and develop the draft items, the experimental study was executed. The experimental study was done by the subject of 11 groups who are undergraduate students in the educational college of C University. The subject was supposed to watch an in-service middle school mathematics teacher's excellent instruction(study) video and to comment the instruction video on the draft items on class critiques. While analyzing the comments of the subject, the revised items on the class critiques were to be develop. Based on this study, from now on, the final and ideal items on the class critiques would be establish to reflect and comment teachers' instruction.

The purpose of this study is to identify the teaching anxiety experienced by instruction librarians of university libraries and to propose support measures to alleviate it. In order to achieve the purpose of this study, a survey was conducted targeting instruction librarians among librarians of group 'A' university across the country. As a result of analyzing a total of 138 valid responses, 84.8% of the librarians responded that they had experienced teaching anxiety. There was no difference in teaching anxiety in terms of library work experience, instruction work experience, instruction frequency, instruction work weight, and librarian role recognition, but there was a significant difference in emotions and readiness before entering the teaching role. As a way to alleviate the teaching anxiety of instruction librarians, it was suggested that the curriculum for user education should be established from the undergraduate course in library and information science, guidelines should be prepared at the level of higher institutions or councils, and to diversify the curriculum of specialized librarian education and training institutions.
