The ARM7 TDMI microprocessor employ a software routine iteration method in order to handle integer division operation, but this method has long execution time and many execution instruction. In this paper, we proposed ARM7 TDMI microprocessor with integer division instruction. To make this, we additionally defined UDIV instruction for unsigned integer division operation and SDIV instruction for signed integer division operation, and proposed ARM7 TDMI microprocessor data Path to apply division algorithm. Applied division algorithm is nonrestoring division algorithm and additive hardware is reduced using existent ARM data path. To verify the proposed method, we designed proposed method on RTL level using HDL, and conducted logic simulation. we estimated the number of execution cycles and the number of execution instructions as compared proposed method with a software routine iteration method, and compared with other published integer divider from the number of execution cycles and hardware size.

The objectives of this study were to measure the effect of Practical Reasoning Instruction in Home Economics : specifically. its effect on developing of critical thinking as well as to evaluate the degree of the critical thinking process. with reference to its sub-factors and the level. The research subjects were consisted of the experimental group of 119 freshman class female students from the “A” High School and the comparative group of 110 freshman class female student from the “C” High School in the city of Chung-Ju. This research was conducted under the pre-post test control group design. administering the Pre-Post testing to both the experimental and the comparative groups. The experimental group was subjected to Practical Reasoning Instruction in Home Economics : whereas the comparative group was taught under the lecture-Instruction in Home Economics The research findings are as follows: 1. Those who studied Home Economics under the Practical reasoning method scored higher on the critical thinking Process than the comparative group students who were taught Home Economics in the lecture-style approach. 2. The experimental group of students. who studied Home Economics under the Practical reasoning method. scored higher than the comparative group in their ability to perceive assumption and to render Judgment among the five sub-factors of their critical thinking processes.

We have been received questionnairs on the general characteristics and cognition of radiotechnological students, instruction which they hope, and the present processing actural states of instruction to 610 numbers of 2, 3 years radiotechnological students in korea. We have been perceived the actural states of radiotechnological instruction by the results of questionnaires, therefore, the imperfections of student's contentment, lack of instruction plan and audio-visual material's practical use, insufficient of study activities on instruction process, lack of clinical adaptation and practice of lecture evaluation were founded. We propose the solving method of these problems as the improvement of instruction. It is necessary for the will and effort of college and teacher to practices these problems.

This study examined the effects of a practical problem based home economics instruction using multiple intelligences teaching and learning methods for the prevention school violence by high school students'. The contents of this study are as follow. 1) Develop the practical problem-based instruction using multiple intelligence and teaching and learning strategies for each protective factor both in teaching method aspects and learning content aspects during the 29-period of lesson plans. 2) Examine the effects of the instruction in the changes of pre- and post- impulsivity and aggression, self-esteem, empathy and attitudes to school violence after implementing home economics lesson plans. 3) Evaluate the instruction. The subjects of this study were 288 first grade students (124 male and 164 female students). The study utilizes a quasi-experimental pre-post design. The effect of the instruction by the paired t-test results showed that the aggression and impulsivity by the learners had been lowered; however, empathy and self-esteem increased; in addition, learners' attitudes toward school violence had changed positively. In conclusion, self-esteem in school as sub-variables of self-esteem increased; however, there was no statistically significant difference.

Web provides a new instruction and learning method to get the interactive learning for people. But it is not efficient for the interaction of the education resources in the Web, and also it is difficult for the accommodative instruction to the learners who need suitable level for themselves. Therefore this thesis proposes web-based instruction system by agent technology that enables to increase the interaction, not losing their own way and learning by level, when the learners have instruction with using of web.

The first thing in designing application-specific instruction set processor is having instruction set closely matching hardware characteristics. This instruction set design problem can be more complicated when cobined with implementation method selection problem of each instruction. Our processor model supports two kinds of instructions-primitive or special instructions. Primitive instructions are implemented using common multifunctional hardware such as ALU. Special instructions require a set of dedicated hardware, which actually functions as a coprocessor to the main processor. In this case, special instructions and primitive instructions can be executed independently. In this paper, we present novel algorithm for genrating special instructions for given application. Parallelism between special instructions and primitive instructions is also considered during the performance estimation stage of generated special instructions.

The purpose of this study is to examine the effects of scaffolding instruction on motivated learning strategies and academic achievement. Subjects of this study were 96 middle school first grade students in Busan, who were randomly assigned to two experimental group and one control group. The one experimental group had received scaffolding instruction by teacher, and the other experimental group had received scaffolding instruction by the interaction of peers. Control group were given traditional lessons only by the method of lecture. Students were given English Academic Achievement Test, Motivated Strategies of Learning Questionnaire. T test and ANOVA were used to analyze date. The results of this study showed that scaffolding instruction by ZPD turned out to have a positive influence on motivated learning strategies and academic achievement.

The burst loading of a pre-created cache-image is an effective method to reduce the instruction cache misses in the early stage of the program execution. It is useful to alleviate the performance degradation as well as the energy inefficiency, which is induced by the concentrated cold misses at the instruction cache. However, there are some defects, including software overhead on the compiler and installer. Furthermore, there are several mismatches as a result of the dynamic properties for specific applications. This paper addresses these issues and proposes a cache-image maintenance/recreation policy that can conduct dynamic management using a hardware-assisted method. The results of the simulation show that the proposed method can maintain the cache-image with a proper size and validity.

This study investigates the effect of play-based software education instruction strategy for improving computational thinking as a method of software education. The play-based instruction strategy is a teaching-learning strategy in which the presented code is navigated through play, and the functions are revised and newly reconstructed. We designed an education program with the play-based instruction strategy and applied the program to elementary students. In order to verify the effectiveness of the research, we examined the competence of computing thinking concept and computing thinking practice. As a result, the computing thinking concept and computational thinking practice were that the proposed teaching-learning model is higher than the direct teaching method.
