This study aims to analyze how the history of mathematics is used in Chinese mathematics textbooks. As a framework for analysis, we categorized nine types of using the history of mathematics in textbooks. We analyzed 18 mathematics textbooks for Chinese elementary and middle schools. As a result, we found that various types of using the history of mathematics were adopted in Chinese textbooks except for explorations of mathematical errors in history. We also noticed three characteristics: preference to using for motivation and reading matters in elementary school levels, high frequencies of using problems from traditional mathematical books and origins of mathematical concepts or symbols, and emphasis on ethnic superiority through the Chinese traditional mathematics. Based on the results of analysis, we discussed and induced some implications for using the history in our mathematics textbooks.

One of the benefits of the internet-assisted instruction is that it can improve L2 Learners' motivation to express themselves in English. The purpose of this paper is to investigate an effective approach to British-American fiction learning in Korean universities, which can emphasize communicative strategies drawing on video-conferencing system, a chat system(CUSeeMe), and an e-mail system. Students are passive participants who cannot assert their creativity in the traditional teaching method of British-American fiction, which mainly relies upon reading and translation far from literature lessons. In CCDL(Cross-cultural distance learning) class, students can play active roles in asserting their own ideas and assuming considerable responsibility for making a presentation in English. A professor can play a role as a coordinator in supporting the students' activities and in winding up the class. The main significance of this article lies in providing a paradigm for CCDL class beyond the limitation of the traditional teaching method of British-American fiction in Korea and futhermore in exploring the eclectic integration of the traditional one and CCDL.

Both coordinated multi-point transmission and frequency reuse are effective approaches to mitigate inter-cell interference and improve network coverage. The motivation of this work is to explore the manner to effectively utilize the spectrum resource by reasonably combining cooperation and frequency reuse. The $Mat{\acute{e}}rn$ cluster process, which is appropriate to model networks with hot spots, is used to model the spatial distribution of base stations. Two cooperative mechanisms, coherent and non-coherent joint transmission (JT), are analyzed and compared. We also evaluate the effect of multiple antennas and imperfect channel state information. The simulation reveals that the proposed approach to combine cooperation and frequency reuse is effective to improve the network coverage for users located at both the center and the boundary of the cooperative region.

This paper determined students' ranks of difficulty on the use of materials in terms of 1) understanding the layout of the learning materials, 2) reading comprehension of the learning materials, and 3) realization on relevance to needs of the learning materials. It also determined students' 4) rank and frequency of attitude on the materials. With the data gathered through 128 survey questionnaires, 7 focused group discussions, and 10 interviews, the results were found out that there was an inappropriate assessment procedure set by this particular university. The researcher concludes that: 1) design of four types of classes by just using the two textbooks with their respective workbooks is grammar-based with limited conversation activities; 2) placement for these students in one big class size was implemented without considering their common interest and motivation and language levels; and, 3) qualification of teachers teaching these EFL students did not support students' real needs and the language program itself. Content professors who were made to teach may have the ability to input learning, but their teaching styles may differ from the ones who are real English teachers. This paper then recommends that teachers and school administration should have an appropriate placement exam before students attend the class, especially in a big class size. There could only be a few problems among students in one big class size when students' level of competence is proportioned. With this, topics and conversation activities can even be more flexible with the maneuver of art of questioning, various dimensions of thinking, strategic competence, learning attitude or behavior, etc. to ensure sustenance of communicative mode and level of interest and motivation in the classroom. Grammar-based instruction can only be taught when a need arises. Thus, the course description of each class will be able to transact the objectives ready for developing students' communication competence. Moreover, proper measurement can be utilized to validly assess the amount of students' learning and the progress of language curriculum design in terms of materials selection and teaching approach.

In this Paper, an Audio-Visual Teaching aid (AVTA) for use in a classroom and with Internet is presented. A system, which was designed and tested, consists of a wireless Microphone system, Text to Speech conversion Software, Noise filtering circuit and a Computer. An IBM compatible PC with sound card and Network Interface card and a Web browser and a voice and text messenger service were used to provide slightly delayed text and also voice over the internet for remote teaming, while providing scrolling text from a real time lecture in a classroom. The motivation for design of this system, was to aid Korean students who may have difficulty in listening comprehension while have, fairly good reading ability of text. This application of this system is twofold. On one hand it will help the students in a class to view and listen to a lecture, and on the other hand, it will serve as a vehicle for remote access (audio and text) for a classroom lecture. The project provides a simple and low cost solution to remote learning and also allows a student to have access to classroom in emergency situations when the student, can not attend a class. In addition, such system allows the student in capturing a teacher's lecture in audio and text form, without the need to be present in class or having to take many notes. This system will therefore help students in many ways.

This paper is written to clarify the specific details of the Sabu-Songyu­Mongnok(사부송유목록). which is a reading list for recitation and appreciation of Chinese classics edited by Hong Suk-Chu(1774-1842) when he was 56 years old for the stimulation of his younger brother Hyun-Ju (1793-1865)'s reading life. In this study the catalogue's title interpretation. the time of the editing, the motive for the editing and the analysis of the contents are revealed as what they actually are. The main details are as followings. There is no date written on the Sabu-Songyu-Mongnok but the writer estimate it to be around 1829. After Hong Suk-Chu recognized the fact that although his younger brother Hyun-Ju was interested in reading but felt that he was a little too old to begin to read all the books of the whole classes. he selected the classic works from whole subjects, i.e. history, philosophy and anthology, that he thought which would best represent each subject. From these selected works he then picked out the most important chapters or parts of the works. Another motivation of the editing was for the stimulation of the reading life for Hong Suk-chu himself and for people like himself who were getting old and losing their vitality. The Sabu-Songyu-Mongnok consists of four categories. i.e. classics category, history category, philosophy category and anthology category, and in the catalogue, 26 different works are entered. The classics category has ten, the history category has six, the philosophy category has six and the anthology category has four. Each of the works are entered under the title of the book, and hen the chapter heading. The Sabu-Songyu-Mongnok was edited 19 years later than Hong-ssi toksorok(홍씨독서록) or an Annotated Bibliography of Korean and Chinese Books. Comparing each category of the catalogue with the Hong-ssi toksorok, the writer could catch the following characteristics. 1. Although there was no indication of the class heading, the sequence of the arrangement of the entries in the classics categories was the same as the sequence of the classes in the Hong-ssi toksorok. 2. The Zuo-shi Chun-qiu-zhuan(좌씨춘추전) is recorded in the class of Chunqiu of the classics category in the Hong-ssi toksorok, but in the Sabu-Songyu­Mongnok, it belongs to the history category. 3. In the philosophy category of the catalogue, Chuangtzu(장자) writings are included because it is so well written. 4. Unlike the categories of classics, history and anthology, the philosophy category is recorded under the author's name. This is fascinating because it unites with the conventional cataloguing practice of the west. 5. In the anthology category, the writings with the best styles from the Chuci(초사) or the poems of Chou, Wen-xuan(문선), wen-yuan-ying-hua(문여영화) are selected and classified into four parts: (1) poems, (2) proses of Han, Wei and Pre-Qin dynasties. (3) Si-liu-pian-li-wen(사육병려문), (4) classic style of writings of Tang and Song dynasties (당송고문). 6. There was an unusually large number of Han Yu's writings selected from the great eight poets of Tang and Song dynasty writings. (20 categories out of $43: 47\%)$ After comparing the entries of the Sabu-Songyu-Mongnok, it can be concluded that all the entries were also included in the Hong-ssi tokrorok. The fact that the sequence of the entries in the classics category and that the literary works were sequenced under the same subject by the year of editing or writing like as the Hong-ssi toksorok Also it is unusual that there was not even one literary work of a Korean in the catalogue. Anyhow this catalogue is the first recitation catalogue in our country that was edited for the people in the prime of life as well as for old people and is the only one existing today.

본 연구의 목적은 학자들의 정의가 반영되어 있는 영재아 행동특성 평정척도(SRBCSS-R)에 비추어 과학영재를 둔 어머니들이 갖고 있는 영재성에 대한 인식을 확인하는 것이다. 이를 위해 초등 과학영재를 둔 어머니 18명과 중등 과학영재를 둔 어머니 32명에게서 영재성에 대한 설문을 실시하고, 이를 언어네트워크분석법을 활용하여 단어분석과 프레임 분석을 수행하였다. 그 결과 단어분석에서는 초등 과학영재를 둔 어머니들이 독서, 과학, 제작 등의 단어에 영재성을 연결시키고 있는 반면, 중등 과학영재들 둔 어머니들은 문제, 문제풀이, 수학 등에 영재성을 연결시키고 있었다. 프레임 분석에서는 초등 과학영재를 둔 어머니들이 창의성, 동기 등의 범주에 강하게 연결되어 있는 반면, 중등 과학영재를 둔 어머니들은 학습, 동기 등의 범주에 강하게 연결시켜 인식하고 있다. 즉, 과학영재를 둔 어머니들의 영재성에 대한 인식은 영재아 행동특성 평정척도에 비추었을 때 일부의 요소만을 영재성으로 인식하고 있었다. 따라서 어머니들의 영재성에 대한 올바른 이해하기 요구되며, 과학영재들에 적합한 교육을 위해서 부모교육이 필요할 것이다.
