The new algorithm for halftone generation for gravure engraving was developed. The basic concept of this algorithm is based on the mapping and equal density expansion methods that we are mapped out. The program was used by the Microsoft Visiul C++2.0 and could be loaded in IBM personal computer.

In this paper, we psropose a virtual information desk using VRML and internet. We review about VRML which can construct a virtual world on the internet. Next, we explain a basic concept of a web-based virtual information desk using VRML and javascript. Implementation details and advantages of the developed system are described also.

본 논문에서는 유연생산시스템 (FMS: Flexible Manufacturing System)의 객체지향 시뮬레이션(OOS: Object Oriented Simulation)에 대한 기존의 연구들을 소개한다. 먼저 FMS와 객체지향시뮬레이션의 일반적인 개념에 대해서 이야기하고 기존의 연구들을 대상 시스템의 추상화(abstraction)과정을 중심으로 분류하여 정리하였다. 추상화 방법론과 FMS를 위한 객체지향시뮬레이션의 현황 및 과제에 대해서도 간략하게 살펴보았다.

Analyzing textbook is the first step for enhancing the level of biology education especially in Korea. Prior studies of textbook analysis have mostly dealt with such topics as terminology analysis, content analysis, relationship analysis of chapters, and comparative studies. However, not much attention was paid to concept system to be learned and to relevance of concepts chosen. Therefore, the purpose of this study is to clarify the concept system and to elucidate the relationship among concepts for effective learning. Novak's concept map was utilized as a theoretical framework for the analysis of chapter I of high school biology textbook. Concept map has several distinctive merits in many aspects such as teaching, learning, and evaluation. It not only makes the understanding of key concepts and proposition a lot easier, but also helps to link prior knowledge and new concepts more effectively. This study will be a basic material for improving textbook for effective biology learning. The conclusions of the study are as follows: 1. Concepts in subchapters were arranged unsystematically or they were overlapping. For more effective understanding, those items should be rearranged. 2. Key concepts are not arrayed properly according to their hierarchy. Therefore, it was hard for students to set up concept structure. 3. The concepts emphasized by bold letters were not selected properly in accordance with their importance. Appropriate concepts should be chosen. 4. Key concepts should be explained by using examples in everyday life for easy understanding. 5. Many concepts in molecular biology is too abstract to grasp their meaning. Therefore, many audio-visual materials should be used to aid concept building.
