The new computer program, visual SolidMech (ver 2.0), for mechanics of materials and structural mechanics has been developed using visual C++. The visual SolidMech is organized in a format similar to most standard texts on mechanics of materials and structural mechanics. This program consists of a number of menus to perform various calculations as well as a set of dedicated graphical user interfaces. Solutions to problems are given in both graphical and numerical forms. The visual SolidMech will help students develop problem-solving skills by showing them the important factors affecting various problem types, by helping them visualize the nature of internal stresses and member deformations, and by providing them an easy-to-use means of investigating a greater number of problems and variations. This new program can be utilized as a supplement to existing texts in mechanics of materials and structural mechanics.

Web Based electronic texts are studied on the statistics education fields. In this paper, we discuss the current problems encountered by many statistics electronic texts. We also suggest a new design concept for the Web Based interactive material. In addition, we presented several examples to demonstrate.

The purpose of this paper is to analyze educational theories and practices represented in the movie Dangerous Minds. This paper begins by giving the overview of the movie. Then this paper makes an analysis of the pedagogical methods and practices used by the teacher in the movie, which can encourage students to fulfill their academic success and social mobility. The lives of students at risk are transformed through the teacher's beliefs and pedagogical practices based on the constructivism, leading students on a path of selfdiscovery and self-empowerment. What is imperative in the students' lives here is their intrinsic motivation and self-efficacy toward the self and their educational system. By providing constructivist pedagogical paradigms and viewing these media texts within the context of an urban school, this paper intends to introduce educational theories and methods which can create better educational environment for students. In short, this study explores teaching theories and methods represented in the movie based on the constructivist perspectives, which are supposed to fully cultivate the potential of students.

This study was undertaken in order to develop practical automatic indexing techniques suitable for Korean natural language texts. It has taken a modest step toward this goal by developing an automatic syntactico-statistical indexing method and evaluating the method by comparing the resutls with manual indexing. For this experimental study, the Korean text database was constructed manually based on 300 abstracts covering business subject. The experimental results showed that the performance of the automatic syntactico-statistical indexing system was comparable to that of other studies which have compared automatic indexing with manual indexing.

Effectiveness of information conveyance in reading is affected by several factors such as line length, letter size, line spacing arrangement as well as typeface itself. This study examined relative importance of these factors by asking people to read the texts that was constituted with non-square form letter and rank the preference of texts through conjoint analysis. In the case of reading time, justification was the most important factor, followed by leading, line spacing, letter width, line length, font size, font type in their order of importance. And in the case of preference decision, letter width was the most important factor, followed by font size, justification, line spacing, leading, line length, font type. The result will be useful in understanding how to consider human preference in the hangul typography.

In this research, a nameplate engraving system for images and texts downloaded through Internet on nameplate is developed. The system consists of two subsystems: thinning algorithm and NC code generation module. In the thinning algorithm, the concept of connectivity is used and center lines of images and texts, which will be used as NC tool paths, can be obtained successfully. Because the center lines are composed of a lot of pixels, NC code would be too long. In the NC code generation module, many useless pixel data are removed and linear interpolation algorithm is applied to only the remaining pixels. By performing actual experiments, the thinning algorithm and the NC code generation module are verified.

Standard Gaussian Mixture Model (GMM) is a well-known method for image segmentation. However, one of its problems is that we consider the pixel as independent to each other, which can cause the segmentation results sensitive to noise. It explains why some of existing algorithms still cannot segment texts from the background clearly. Therefore, we present a new method in which we incorporate the spatial relationship between a pixel and its neighbors inside $3{\times}3$ windows to segment the text. Our approach works well with images containing texts, which has different sizes, shapes or colors in case of light changes or complex background. Experimental results demonstrate the robustness, accuracy and effectiveness of the proposed model in image segmentation compared to other methods.

Objective : This study is about how the theory on ten kinds of prescriptions has been developed and how it has been applied for in prescription books and clinical texts. Methods : I made a comparison of this theory in prescriptions books and clinical texts. After it, I investigated the developing history based on it. Results and Conclusion : This theory had been used for classification of not prescription but herb, until Cho Gil(趙佶) and Seong Mugi(成無已) enlarged its meanings. The first mention about it was made by Jin Janggi(陳藏器). Yu Wanso(劉完素) gave it more definite meanings by showing prescription examples than before. Jang Jahwa(張子和) corrected what Yu Wanso explained. Besides, someone for example, Gu Jongseok(寇宗奭), Mok Huiong(繆希雍), Seo Chunbo(徐春甫), and so on added some kinds of prescription.

Objectives : To investigate how 『Duchanggyeongheombang』 has been adopted and edited in practical texts such as 『Gosachwalyo』, 『Sallimgyeongje』, 『Gosasinseo』. Methods : Based on the disassembled verses of a paragraph in the 『Duchanggyeongheombang』, the 「Duchanggyeongheombang」 contents in 『Gosachwalyo』, 『Sallimgyeongje』,『Gosasinseo』 were compared and examined. Results : 『Gosachwalyo』 directly summarized and quoted the contents of 『Duchanggyeongheombang』 written by Park, Jinhee, while the contents in 『Sallimgyeongje』 and 『Gosasinseo』 are mostly similar, summarizing and quoting from 『Gosachwalyo』. Conclusions : In the perspective of text categorization, while the professional and specialized contents of 『Duchanggyeongheombang』 has been excluded, it was edited in ways of increasing practicality. As these texts were widely dispersed to the public, we can conclude that 『Duchanggyeongheombang』 was very influential in the treatment of douchang(痘瘡, smallpox) among the public.

Objective : I will study about similarities and differences of furunculus section between Sonjininchungeumbang and Bigeupchungeumyobang. Method : I compare furunculus section of Sonjininchungeumbang with Bigeupchungeumyobang to investigate changes of texts. Result : I can find significant differences of furunculus section between Sonjininchungeumbang and Bigeupchungeumyobang, specially the 3rd prescription of Balbae(發背方第三), the 6th prescription of Pyojeo(瘭疽方第六). Conclusion : Sonjininchungeumbang is a prescription book which is compiled in Dang dynasty. And Bigeupchungeumyobangis is a revised version of Sonjininchungeumbang which is compiled by the Bureau for Revising Medical Texts(校正醫書局) in Song dynsasty. Bigeupchungeumyobangis shows the added medical knowledge about furunculus in Song dynsasty.
