Embedded processors often accommodate two instruction sets, a standard instruction set and a compressed instruction set. With the compressed instruction set, code size can be reduced while instruction count (and consequently execution time) can be increased. To achieve code size reduction without significant increase of execution time, this paper proposes a new compressed instruction set architecture, called TOE (Two Operations Execution). The proposed instruction set format includes the parallel bit that indicates an instruction can be executed simultaneously with the next instruction. To add the parallel bit, TOE instruction format reduces the destination register field. The reduction of the register field limits the number of registers that are accessible by an instruction. To overcome the limited accessibility of registers, TOE adapts non-homogeneous register partition in which registers are divided into multiple subsets, each of which are accessed by different groups of instructions. With non-homogeneous registers, each instruction can access only a limited number of registers, but an entire program can access all available registers. With efficient non-homogeneous register allocator, all registers can be used in a balanced manner. As a result, the increase of code size due to register spills is negligible. Experimental results show that more than 30% of TOE instructions can be executed in parallel without significant increase of code size when compared to existing Thumb instruction set.

Objectives: Subjects of this study were technical high school students. It researched students' smoking status, smoking attitude, smoking perception and willingness to quit smoking, providing them with a five-day-smoking cessation program. Methods: Data collection proceeded from April to August 2008. The subjects were the whole number, 38 students, of 1EA technical high school located. The subjects who attended the smoking cessation program were the first and second grade students of the high school whom classroom teachers recommended. As to the subject, I comparatively analyzed differences between the before and after instruction, between after instruction and after consecutive consulting, and between before instruction and after consecutive consulting. The five-day-smoking cessation program took 2 successive hours a day for five days. Results: Average age for them to start smoking was 13.6 and to form smoking habits was 15.5. Average smoking period was 31.6 months and average smoking quantity was 11.2 cigarettes. As a result of the five-days smoking cessation program, 10.5% of the participants quit smoking and smoking quantity also significantly reduced. After instruction, willingness to quit smoking was generally higher than before. Smoking attitude, especially toward adolescent smoking, changed to be more negative than before. Perception of smoking also changed to be positive. Conclusions: The results from the comparative analysis of before and after instruction revealed a decrease on smoking quantity of the participants who attended the smoking cessation program. It also showed a significant change on smoking attitude, willingness to quit smoking and smoking perception.

The purpose of this study was to evaluate the effects of Web-based nutrition education program for junior and senior high school students. Three materials, which were printed materials on Group I, WBI (Web-Based Instruction) leaflet on Group II and the web-based nutrition education program developed in the antecedent research, were applied for 564 students in 3 junior high school and 4 senior high school in Seoul during 4 weeks. Pre-test was done from October 21 to October 26, 2002 and post-test was done from November 25 to December 13, 2002. The statistical data analysis was completed using SPSS WIN (ver. 11.0) for descriptive analysis, t-test and ANOVA. According to the evaluation of effectiveness for web-based nutrition education program, nutrition knowledge, food attitude, food habit and nutrient intake were not significantly improved but positively. And on the evaluation of effectiveness for nutrition education program by materials, WBI was more effective educational materials than WBI leaflet and printed materials. Consequently nutrition knowledge, food attitude, food habit and nutrient intake were improved positively but not significantly using WBI, which was due to the instructional period of the only 4 weeks. Therefore long-term instruction should be required for effective nutrition program, as well as more WBI nutrition education program for high school students would need to be developed in the near future in that WBI was effective material on nutrition education.

Open education can be defined as education which apply rule of respect, rule of freedom, rule of individual instruction, and rule of environment. The purpose of this study was to look into the present condition of individual instruction, to find the problems of instruction, especially ill practical arts, and then to suggest the improvement plans on the problems. In order to solve the problems, after briefly reviewing theoretical background of open education, we suggested a CAI(Computer Assisted Instruction) program which was made by Chinju National University of Education and KEDI(Korean Educational Development Institute). And then we applied the program to the classes of the 4th grade of elementary school. In this thesis, we didn't analyze the result of the questionnaire or interview, however, it is believed that using CAI program is a adaptive lesson method of individual instruction.

The purpose of this study is to investigate how the different types of reading instruction programs and reading methods influenced the creative ability and the self-directed learning ability, They were divided into two groups. Class A was taught to use 'The Author-Reader-Inquirer Cycle'. which concentrated on the writing-centered reading program model. Class B was taught to use 'The Literature Circles'. which concentrated on the speaking and listening-centered reading program model. After reading instruction. the creative ability and the self-directed learning ability increased. The writing-centered reading instruction was more effective than the speaking and listening-centered reading instruction. The reading instruction during the long-period was more effective than that during the short-period. The 'intensive reading' among the reading methods had a significant influence on the creative ability and the self-directed learning ability.

Much of the current literature on reading instruction supports the idea of teaching students a series of reading strategies instead of isolated reading skills. Reading strategies are plans or methods that can be used or taught to facilitate reading proficiency. In the meantime, the reading instruction program of school library is the reading promotion event has been limited. Therefore, the reading instruction program of school library need to focus reading strategies oriented instruction rather than reading skill. This Study categorizes Reading Strategies that divided into text type, text structure, reading process, cognitive strategies.

The purpose of this study is on Effect of Teacher Librarian Information Literacy on Library-Assisted Instruction and on searching the method of increasing the Information Literacy. The result of this study indicates that there is no statistically meaningful between the Library-Assisted Instruction and Teacher Librarian's Information Literacy. However the School Library-Assisted Instruction extremely lacks forming a scheme and Information Literacy extremely lacks Information seeking Therefore subject teachers and the librarian teachers need to reinforce the cooperation to reinvigorate the School Library-Assisted Instruction and systematic training program of Information seeking have to be practiced to increase Librarian Teacher's Information Literacy.

This paper proposes a program counter unit(PCU) on the pipelined architecture of RISC (Reduced Instruction Set Computer) type high performance processors, PCU is used for supplying instruction addresses to memory units(Instruction Cache) efficiently. A RISC processor's PCU has to compute the instruction address within required intervals continnously. So, using the method of self-generated incrementor, is more efficient than the conventional one's using ALU or private adder. The proposed PCU is designed to have the fast +4(Byte Address) operation incrementor that has no carry propagation delay. Design specifications are taken by analyzing the whole data path operation of target processor's default and exceptional mode instructions. CMOS and wired logic circuit technologic are used in PCU for the fast operation which has small layout area and power dissipation. The schematic capture and logic, timing simulation of proposed PCU are performed on Apollo W/S using Mentor Graphics CAD tooks.

Although many elementary school students love to read edutainment comics, they are not appropriately guided when they read those books. This study aimed to suggest the necessity of reading instruction for the edutainment comics. To achieve the purpose of this study, we examined the 8 chapters programs of reading instruction-for the 4th grade students-in 2 times. After carrying out the 1st program, we found out the problem related to the program and developed the trouble shooted the 2nd program. The purpose of this study is to show necessity of reading instruction on the edutainment comics in order to activate students' reading. This research shows that if teachers use edutainment comics appropriately to teach students with learning difficulties and reading difficulties, they might help the students by developing their learning abilities and enthusiasm for reading. This study suggests reading guidance program should be used to improve students' learning and reading activities as elementary school students can have more interests to specific topics through the edutainment comics.
