Recently classroom monitoring is becoming important since the lecture is being held in the classroom and academic institutions are interested in the quality assurance. Some institutions have adopted ISO 9000 systems and constructed monitoring system through measurement, analysis and improvement. In this study quality assurance problems in academic institutions and the requirements of ISO 9001:2000 will be briefly discussed. Next we will investigate how to monitor the lecture in the classroom(in-class) using statistical process control techniques such as control charts. Then case study will be given to illustrate the technique to use appropriate statistics. Finally how to monitor the learning process during in-class and after-class will be proposed.

공격 방법의 다양화와 지능화에 대응하기 위해 침입탐지시스템(IDS)의 성능도 향상되고 있다. 특히, 데이터 마이닝 기반의 침입탐지시스템은 기존 침입탐지시스템의 많은 문제점을 개선시켰다. 그러나 데이터 마이닝에 기반한 침입탐지시스템의 탐지 정확도가 트레이닝 데이터(training data)에 포함된 속성(features)과 선택된 axis 및 reference 속성에 의해 결정됨에도 불구하고 현재의 데이터 마이닝 기반의 침입탐지시스템은 트레이닝 데이터에 포함된 고유의 속성만을 고려하기 때문에 탐지 정확도를 향상시키는 데는 한계가 있다. 따라서 본 논문에서는 데이터 마이닝에 기반한 침입탐지시스템의 탐지 정확도를 향상시키기 위하여 기존 데이터 마이닝 기반의 침입탐지시스템이 고려했던 고유의 속성 외에 침입과 밀접하게 관련되고 axis및 reference속성으로도 사용될 수 있는 새로운 속성을 제안한다.

In this paper, a novel technique that improves the performance of generalized mixture decomposition algorithm (GMDA) based on pre-training phase unwrapping. From the investigation of the GMDA scheme, it was discovered that the conventional GMDA technique cannot fully consider phase unwrapping, because the estimated inter-channel phase difference (IPD) slope is initialized randomly. To avoid this phenomenon, the proposed GMDA approach initialized the IPD slope from the data of low-frequency bins. Experimental results show that comparing to the conventional GMDA technique, the proposed GMDA technique based on pre-training phase unwrapping obtains a lower estimation error. When integrated into a source localization system, the result of source localization is improved.

The performance of a MIMO system with adaptive modulation (AM) and space-time coding over Ricean fading channels for perfect and imperfect channel state information (CSI) is presented. The fading gain value is partitioned into a number of regions by which the modulation is adapted according to the region the fading gain falls in. Under a target bit error rate (BER) constraint, the switching thresholds for AM are given. Based on these results, we derive the calculation formulae of the theoretical spectrum efficiency (SE) and average BER. As a result, closed-form SE expression and accurate BER expression are respectively obtained. Besides, using the approximation of complementary error function, a tightly closed-form approximation of average BER is also derived to simplify the calculation of accurate theoretical BER. Computer simulation shows that the theoretical SE and BER are in good agreement with the corresponding simulation, and the approximate BER is also close to the accurate one. The results show that the AM scheme in Ricean fading channel provides better SE than that in Rayleigh fading channel due to the direct-path propagation, and has performance degradation in SE and BER for imperfect CSI.

This paper presents the cyber education system which aims to improve the effect of cyber education that remains limited by uniform educational course being provided to all students. In this respect, a cyber English educational program has been provided to all individual students in different levels through combining CRM with WBI. The paper has analyzed the academic interest of each learner in the process of education using the algorithm that this paper proposes. Here the CRM algorithm enables the study to categorize the degree of learners interest in the process of education and utilize this in cyber education. The frame of education program based on the students' interest which is introduced in the paper is expected to contribute as one of the cyber education strategies that will increase the learners' academic interest.

The purpose of this study was to provide information on how to improve both the satisfaction and the current sizing system for the school uniform focused on middle and high school girls' students. For the satisfaction of their school uniform, there were statistical significance by the academic year in jacket design, blouse color, and skirt design in the case of middle school girls'. On the other hand, high school girls' evaluation of school uniform was significantly different in jacket color, jacket design, blouse color, textile of blouse, skirt color, and skirt design by the academic year. For the assessment of wearing motion, there was no significant difference by the grade in both middle school and high school girls'. However, it was shown more frequency of discomfort than that of comfort. For the evaluation of sizing fitness, the breadth of sleeve in jacket and the width of blouse were statistical significance in middle school girls' by the grade while the width of jacket, he breadth of sleeve in jacket, the length of blouse, the width of blouse and length of sleeve in blouse were different in high school students by the grade.

Gwae(卦氣) theory was one of the main theoretical foundation of yiology in the Han(漢)-dynasty. It was based on the concept that the trigram or hexagram of the book of change corresponds to the seasonal point such as 24 solar terms in one year, so there was so much influence from astronomy and divination system of that time in the development of theoretical principle of Gwae(卦氣) theory. Since Han(漢) Dynasty, the theoretical method such as Gwae(卦氣) theory that correlates the astronomy and divination system with the book of change, had become one of the main academic thoughts throughout the entire history in China, and it was also like that in medicine. Nevertheless there still exists the skeptical sights that Gwae(卦氣) theory was not a part of orthodox yiology, that had been developed by Confucian scholar and had also been recognized as the right path to the study of the book of change. Nowadays because of the new opportunity such as the excavation of the ancient silk script, this kind of controversy has moved on its another step. With regard to this problem, this article will treat the current thoughts about the Gwae(卦氣) theory and think about the substantial basis of each point of view.

This study attempts to reorganize the knowledge classification system for the research fields and majors in education by designing a new classification schedule. Content analysis of the majors and curriculums in the universities and major areas of the academic professors in Korea, and the comparison with the various headings in several classification systems for research fields were carried out. Based upon the comparison with library classification systems and reviews and opinions of subject specialists in major disciplines, finally, a knowledge classification system composed of three parts - schedules, tables and a relative index - was presented. The proposed classification scheme was tested for classifying the research projects listed in the 1998 catalog of the academic research funded by Korea Research Foundation. Also, several ways for developing a more useful knowledge classification scheme to organize disciplinary information effectively and to encourage interdisciplinary research were suggested.
