The purpose of this study is to know if there are any differences between satisfactions about professional basketball league facilities and circumstances, and to analyze influences which facilities and circumstances make on a revisit intention. Examples of this study are spectators who purchased Korean men's professional basketball regular league tickets in 2003. Examples are 600 people and they are collected from Nov. 22, 2003 to Dec. 3, 2003 and first examples were 630 but incongruities were excepted. A One-Way ANOVA was conducted to know spectators' satisfaction differences followed by social demographic features and we got following results through the Multiple Regression Analysis to know effects which the satisfaction influences upon the revisit rate. First, there were differences on professional basketball pans' satisfactions about facilities and circumstances. In all factors but a 'stadium outline' factor. there appeared differences between other types of pans. One type of pans which supports a basketball team strongly showed higher satisfactions about facilities and circumstances than the other type of pans. Second, in professional basketball pans' satisfaction factors about facilities and circumstances, it was showed that the access to the stadium and event factors in the stadium influence affirmatively upon the revisit intention.

This paper is results of numerical analysis to investigate stress-strain behavior of sandy soils. Tree different constitutive relationships of Modified cam-Clay Model, Hyperbolic Model and Lade's Double-Work-Hardening Model were applied to predict stress-strain behavior of them. For each model, constitutive relations as well as parameters governing stress-strain behavior were programmed numerically. Weathered granite soil, tests were carried out with rich in Korea, and Ju Mun Jin Standard Sand were used as specimen of sandy soil. Stress-strain behaviors of these soils were obtained by performing isotropic compression and drained triaxial compression tests. For Weathered granite soil, tests were carried out with three different water contents determined on the basis of compaction test results. Four different relative densities were used with Ju Mun Jin Standard Sand. Numerically Predicted results with three different models were compared with tested results. Therefore applicability and problems of each model were discussed. Numerical analysis about sensitivity of parameters was also performed to investigate how these parameters influenced stress-strain behavior of sandy soils.

황병곤,이상열 대구대학교 정보통신연구소 2003 情報通信硏究 Vol.1 No.2

대부분의 멀티미디어 검색시스템은 아직까지 내용기반에 의한 검색기술이 실용적 사용이 어려우므로 텍스트기반 검색을 하고 있다. 본 논문에서는 Web상에서 미디어 정보를 검색하는 것으로, HTML문서상에 있는 텍스트 중 이미지의 표제나 이미지 링크상의 텍스트를 추출하여 색인 정보로 사용하였다. 이 텍스트 추출방법은 기존의 N-Gram색인 방법에 질의자의 선택 가중치를 부여하므로 검색 효율을 높일 수 있다. As most Multimedia retrieval system is using text based retrieval not be practical to content based retrieval can not be practical to it. In this paper, we retrieve multimedia contents in the web. After extracting the texts to express the name and link of images. We used them as indexing information in item. We add the weight of the user to the existing N-gram indexing method. Therefore, we can incase a retrieval efficiency.

방상원,정병수,오수열 木浦大學校 情報産業硏究所 1994 情報産業硏究誌 Vol.2 No.-

다층 퍼셉트론은 우수한 일반화 성능과 구현의 용이함 때문에 많은 문제에 사용되고 있다. 다층 퍼셉트론에서 사용되는 중간층 노드의 수는 적용되는 문제에 따라 달라지므로 문제의 복잡도에 따라 적정한 수의 중간층 노드를 설정하여야 한다. 그러나 적정한 수의 중간층 노드의 수를 학습을 시작하기 전에 미리 알아내는 것이 어려우므로 충분히 많은 중간층 노드를 사용하여 학습하다가 학습이 종료된 후에 불필요한 노드를 찾아내어 제거하는 방법을 일반적으로 이용한다. 본 논문에서는 이 문제를 다층 퍼셉트론을 이용하여 일반화된 세선화 template를 추출하는 실험에 적용하여 실험하였다. Multi-layer perceptron is used in many problem because its generalization performance is good and implementation is easy. The number of hidden node is different according to complexity of applied problem, so we must set suitable hidden node. But it is difficult that know suitable number of hidden node before learning, therefore, hidden node is reduced after learning. In this paper, node reduction algorithm is simulated on Generalized Template Matching (GTM) problem and optimized GTM is obtained.
