이항재,강명웅 순천향대학교 1992 논문집 Vol.15 No.3

The purpose of this study was to examine educational suggestions by investigating the relationship of affective characteristics and school achievement of elementary school children. The affective characteristics selected for this study were educational selfconcept, study habit, and the attribution of success and failure. The hypotheses were as follows. 1.There will be significant correlation between educational self-concept and school achievement. 2.There will be significant correlation between educational self-concept and school achievement. 3.There will be significant correlation between attribution of success and failure and school achievement. The subjects were 480 children from 7 elementary schools in a city and rural areas of Chung Name (240 4th graders and 240 6th graders.) Test of Affective Characteristics in Learning developed by Byungryang Park was used for self-concept and study habit, and the instrument used by Miri Lee in "Relationship between Attribution and Achievement Motive" was used for attribution of success and failure. The results of school achievement test carried out by Chung Name Educational Reaearch Center was used for school achievement. The data were analyzed by correlation analysis and t-test 1.There was significant correlation between educational self-concept and school achievement (P<.01). No significant differences were found between children of different areas or grades. 2.There was positive correlation between study habit and school achievement. The correlation coefficients were r=.57 in city, r=.61 in rural areas, r=.64 in 4the graders, r=.56 in 6th graders. Also, there was significant difference of correlation between 6th graders of city and rural areas. There was positive correlation (r=.56) between attentiveness behavior and school achievement. The influence of attentiveness on school achievement was higher in case of children in the city (t=5.26, P<.001). The correlation of skill application behavior and school achievement was positive (r=.52) except in case of 6th graders of the city. There was also positive correlation between self-study behavior and school achievement (r= .48). No significant differences sere found between areas or grades. 3.In order to investigate the correlation between attribution of success and failure and school achievement, ability, effort task difficulty, and fortune attribution factors of two groups divided by school achievement groups attributed their own success, others success, and success of both cases to effort factor mostly, and then ability, task-difficulty, or fortune factors. There was significant difference between effort and ability factors in case of higher achievement group; and fortune and task-difficulty factors, in case of lower achievement group. There was also significant differences between effort and ability factors in case of higher achievement group of city, and effort factor in case of higher group of rural areas, and fortune and task-difficulty factors in case of lower achievement group of rural areas. Both higher and lower achievement groups attributed their failure to effort mostly, and to fortune factor leastly. Effort and task difficulty factors in case of higher achievement groups and fortune and ability factors in lower group showed significant differences. Also, effort factor of higher achievement group and fortune factors of lower achievement group of the city showed significant differences; while, effort factor and task-difficulty factor of higher group, and fortune and ability factors of lower of rural areas shower significant differences.

Owing to the curriculum's revision of primary and high school in the beginning of 1970, several elementary concepts of modern mathematics were introduced as new teaching contents. So the efficient ways to reeducate the present teachers and to publish a desirable textbook have been badly needed. In this paper, we investigate the present situations of administration and teachers of mathematics department in the city and rural area. On the basis of these results, we find out the better ways of mathematics education from the following points of view: 1. The general administrations of mathematics department. 2. The reeducation and education for mathematics teachers. 3. Mathematics textbooks. 4. Evaluations and tests.

계층적이고 반자동적인 비디오에서의 객체 추출 방법

박현재,강행봉 가톨릭대학교 자연과학연구소 2001 자연과학논문집 Vol.22 No.-

객체 기반 압축 기술은 MPEG-4에서 이용되는 기술로 객체와 배경을 따로 압축하는 방법이다. 이 방식은 압축률을 높임과 동시에 객체들간의 재합성 및 검색 등에도 이용할 수 있는 장점이 있다. 하지만, 활발한 연구에도 불구하고, 객체와 배경을 완전하게 구분해내는 알고리즘은 아직 개발되지 않고 있다. 본 논문에서는 자동화에 어려움이 있는 객체 추출 기법을 사용자의 상호 작용에 의한 반자동적인 방법으로 추출하는 방법을 제안한다. 이 방법에는 M-RSST를 이용해 공간적인 분할을 실시한 뒤에 모션 정보를 이용해서 분할된 영역들을 합병한다. 그 후 BPT에 의해 영역의 크기를 조절하며, 사용자가 원하는 영역을 선택하게 함으로써 객체 추출 과정을 간략하게 한다. Object-based coding has become one of the most actively researched areas in the past years because it can increase transmission-rate remarkably. Object-based coding system requires object extraction skill. The object extraction skill enables the system to efficiently compress pictures and to synthesize or edit pictures and videos. It can be useful in many other areas as well. While the research of the object extraction has been advanced, the algorithm, which extracts the object from its background, has not been extensively researched yet. In this paper, we propose a new semi-automatic object extraction approach for the algorithm. This proposed algorithm utilizes a user's actions to precisely extract foregrounds. This algorithm uses spatial segmentation based on color similarity and temporal segmentation to decrease the number of a user's operations. Spatial segmentation performs M-RSST(Multi-resolution Recursive Shortest Spanning Tree) followed by construction of BPT(Binary Partition Tree) of the image. M-RSST divides an image into several regions and BPT enables a user to select regions which he or she wants. Temporal segmentation is performed to merge regions that have similar motion.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Dewey와 Russell의 實驗學校 考察 : 兒童敎育實際를 中心으로 The practice of child Education

李恒宰 순천향대학교 1991 논문집 Vol.14 No.3

This study is to investigate the experimental schools of John Dewey and Bertrand Russell. There have been many other studies on the contribution of J. Dewey and B. Russell on school society, but they were confined to educational theories of Dewey's and Beacon Hill's schools; however, their experimental schools have been neglected. Therefore, instead of fragmentary aspects, this study is to investigate their child education practices. This paper is a comparative study on the experimental schools of J. Dewey and B.Russell. The purposes of this study are as follow. 1. To compare experimental schools of child education of J. Dewey and B.Russell. 2. To obtain suggestions for modern education of Korea. The common factors of this study are the emergence from traditional teaching method and the innovation of a view of school. This study will provide a good suggestion for Korean education, and contribute to social reconstruction; the followings are to be investigated. First, the educational theory and philosophy of Dewey and Russell were based on the concept of freedom, and they practiced it through experimental schools. Second, desirable understanding of J.Dewey and B.Russell will bring out a good suggestion for the establishment of educational objectives of Korea. Third, the freedom of J.Dewey, and the freedom and discipline of B.Russell must be practiced in education. Freedom in education is necessary.

In this paper, I would like to investigate about "performance evaluation techniques" and "performance evaluation factors" used in performance analysis for systems in network based distributed system, image conference system and parallel processing systems. The aim is to propose profitable performance evaluation factors and performance evaluation techniques. For this, I went through similar systems to evaluation factors and performance evaluation techniques. For this, I went through similar systems to evaluate the performance of MICS(Medical Image Conference system)which is still being developed and worked out performance evaluation factors and evaluation methods to evaluate performance of system.
