텍스트로부터의 자동 디지털 영상제작을 위한 카메라 자동 제어
장세민(Se-Min Jang),박종철(Jong C. Park) 한국정보과학회 2004 한국정보과학회 학술발표논문집 Vol.31 No.1B
영화를 제작하는 과정에 필수적으로 사용되고 있는 대본(臺本)에는 필요한 부분마다 영상기법이 명시되어 있어서 실제 장면을 구현하는 과정에 원작자가 의도하는 상황을 비교적 정확하게 재현하는 것이 가능하다. 이에 비하여 교통사고 사건보고서나 동화 등을 기반으로 디지털 영상을 자동으로 제작하려는 경우 이러한 영상기법이 명시되어 있지 않다. 그러므로 자연언어로 기술된 자료로 부터 디지털 영상을 자동으로 제작하기 위해서는 작가의 의도를 파악하여 적절한 영상기법을 추출 하는 방안이 있어야 한다. 본 논문의 선행 연구에서는 동화를 대상으로 하는 애니메이션 자동 생성을 위해서 시간 관리, 참조 해결, 위치 설정, 세부 명령 결정 및 다수 캐릭터 제어 등의 요소 기술이 필요하다는 것을 보이고 특히 시간 관리 중에서 적절한 장면전환이 필요한 경우를 자동으로 파악하는 방안을 제시하였다. 본 논문에서는 결합범주문법을 사용하여 동화 문장에 나타나는 작가의 의도를 분석하고, 이에 부합하는 다양한 카메라 운용기법을 자동으로 파악하여 적용한 디지털 영상 제작 방안을 제시하고 구현한 시스템을 보인다.

Objective: To induce a mouse model of scleroderma with repeated bleomycin injections for research into human scleroderma at our research laboratory. Methods: The protocol of Yamamoto et al. was replicated to establish the bleomycin-induced mouse model of scleroderma. Results: A mouse model of scleroderma was induced by repeated subcutaneous injections of bleomycin. The dermal thickness increased with homogeneous and thickened collagen bundles. Semiquantitative measurements of dermal fibrosis were prominent in bleomycin-treated mice. Conclusion: A mouse model of scleroderma was induced with repeated injections of bleomycin at our laboratory.

The results of the measurement of the flow-rate coefficient (Cv-value) and the analysis of a small ball valve are summarized follows. The Cv-values of 1/2-, 3/4- and 1-inch ball valves were measured using a flow-rate measurement test. The manufacturer obtained the Cv-value using a theoretical calculation method. The new experimental measurement and analysis method yielded more reliable results. In addition, the Cv value obtained through numerical analysis was almost identical the value provided by the manufacturer, which was based on experimental results. A Study on Flow Analysis results are all similar appearances as the reliability of the results.
중학교 수학과 CAI 프로그램 개발 연구 : 이차함수의 그래프를 중심으로 Focused on the graph of quadratic function
張世敏 한국학교수학회 1998 韓國學校數學會論文集 Vol.1 No.1
In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws, acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, character and movement state of various quadratic function graph types can be used. Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Then, students understand the mathematical concepts and the correct quadratic function graph correctly. Consquently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the quadratic function graph", which exists in mathematical curriculum the middle school. When this program is used for students, it is expected the following educational effect. 1. Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 2. This program will cause students to from the mathematical concepts correctly. 3. By visualizing the process of drawing the quadratic function graph, students understand the quadratic function graph structually. 4. Through the feedback, the recognition ability of the trigonometric function can be improved. 5. It is possible to change the teacher-centered instruction into the student-centered instruction. For the purpose of increasing the efficiencies and qualities of mathmatics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher's role, tearchers have to use the CIA program carefully.
