LIBL(Linguistic Instruction Based Leaning) is an effective learning algorithm for fuzzy controller which interpretes and uses natural language of human The possibiliy of the LIBL algorithm to the fuzzy control of dynamic systems is investigated in this paper. Rise time, percent overshoot, and steady stste are proposed as suitable meaning elements for dynamic systems. A supervisor is able to give "higer-level linguistic instruction" to the learning algorithm through these three meaning elements Simulation results for a DC servo motor show the validity of the proposed algorithm.

The architecture of microprocessor for a embedded system should be one that can perform more tasks with fewer instruction codes. The machine codes that high-level language compiler produces are mainly composed of specific ones, and codes that have small size are more frequently used. Extended Instruction Set Architecture (EISC) was proposed for that reason. We have designed pipe-line system for 64 bit EISC microprocessor. function level simulator was made for verification of design and instruction set architecture was also verified by that simulator. The behavioral function of synthesized logic was verified by comparison with the results of cycle-based simulator.

In this paper, the instruction set and the architecture of a RISC processor for programmable logic controller is suggested. From the measurement of existing programs, the characteristics of ladder instructions are analyzed. The instruction set is defined so that the existing ladder program can be reused with simple translation. Because bit instructions controls the behavior of word instructions, the processor suits for high level language like SFC. Simulations show that the PLC with the suggested processor is twenty times faster than the PLC with the multi-purpose microprocessor.

This paper proposes on-chip instruction and data cache memories on RISC reduced instruction set computer) architecture which supports fast instruction fetch and data read/write, and enables RISC processor under research to obtain high performance. In the execution of HLL(high level language) programs, heavily used local scalar variables are stored in large register file, but arrays, structures, and global scalar variables are difficult for compiler to allocate registers. These problems can be solved by on-chip Instruction/Data cache. And each cycle of instruction fetch, pad delay causes the lowering of the processors's performance. Cache memories are designed in CMOS technology and SRAM(static-RAM), that saves layout area and power dissipation, is used for instruction and data storage. To speed up and support RISC processor's piplined architecture efficiently, hardwired logic technology is used overall circuits i cache blocks. The schematic capture and timing simulation of proposed cache memorises are performed on Apollo DN4000 workstation using Mentor Graphics CAD tools.

The purpose of the study is to investigate the effectiveness of the cultural instruction based on the critical pedagogy through film. The participants were 21 college students enrolling 'Understanding American/British culture'class and the class was 15 week long. During class, they discussed and selected the cultural topics related to the movies, complete the research papers, and then gave presentations. The students' portfolio, which consists of the goal statements, research papers, and the reflective journals, was analyzed to investigate the effectiveness of the instruction. The results showed that the instruction was effective in five aspects. They are, 1)accumulation of the cultural knowledge, 2)better understanding of the target culture and its people, 3)acquisition of the critical perspectives toward the target and their own cultures, 4)teaching method, and 5)increase of the motivation for studying other cultures. The study suggested that the instruction should be applied to English-medium class with more advanced students.

Listening comprehension is an integrative and creative process of interaction through which listeners receive speakers' production of linguistic or non-linguistic knowledge. Improving listening comprehension requires continual attentiveness and interest. .Listening skill can be extended systematically only when students are frequently exposed to a wide range of listening materials with an affective, cultural, social, and psycholinguistic approach. Therefore, teachers should help students learn how to comprehend intactly the overall meaning of intended messages. Practical classroom teaching necessitates a systematic procedure in which students should take part in meaningful tasks and activities. This study purposes to investigate the effects of task-based listening comprehension instruction on improvement of EFL learners' listening comprehension and their attitude and interest. 74 freshmen who enrolled in College English conversation classes in Kongju National University participated in this study. The participants were administered listening comprehension tests and questionnaires. The results show that the listening comprehension instruction through tasks and activities has a positive impact on EFL learners' improvement of listening comprehension and their attitude and interest toward the target language as well.

This paper analyzed the effect of using a content-based English textbook in teaching English to Korean college students. The textbook reflected the recent trend in EFL/ESL development that subject matters should be taught as part of the language instruction. The analysis of the questionnaire survey conducted to college students at the end of the semester revealed an encouraging result that this new type of ELT college textbook is effective in helping Korean college students prepare for learning their subject areas through English. Based on this positive outcome, a suggestion is made that the current general purpose college English teaching curriculum be shifted toward a content-based specific purpose type to accommodate the increasing demand of learning subject areas through English in colleges in Korea.

Research studies have shown that phonological awareness focused analogies and anagrams can be used as an effective game-based teaching instruction. However, previous studies used analogies and anagrams as separate instructional tools, especially in EFL-related situations. There has been no vocabulary learning in analogies/anagrams instruction provided, nor has there been usage of an integrated workbook for 'vocabulary learning and analogies/anagrams'. This study examined the effect on learners' vocabulary acquisition scores when a truly phonological awareness integrated 'analogies/anagrams and vocabulary learning' workbook was used as an instructional practice workbook. The results show that the phonological awareness integrated instruction significantly increased learners' vocabulary acquisition scores among 40 college students with minimal or basic level of English proficiency.

The goal of this study is to explore the possibility of applying the podcasting in Korean education for foreign students. To achieve this goal, concepts and applicability of the podcasting is discussed. Previous studies on foreign language education are reviewed and the cases on Korean language education based on technology using mobile phones are investigated. Some of the outstanding merits of the podcasting are found to be its accessibility, mobility and variability along with its room for control by the learners. It also enables the learners to be motivated and to enhance their learning ability. In addition, the podcasting with the content-based instruction is applied for the foreign students majoring in business and its results and implications are discussed. Based on the above results of this study, more active discussions are expected on such issues as educational designs through the podcasting, related variables and the performance evaluation.
