영상검색은 문자위주의 검색의 한계로, 그 내용에 기반 한 특징벡터를 이용하여 검색을 수행한다. 특징벡터간의 거리를 계산하고 그 값들에 순위를 매긴다. 이렇게 얻어진 순위 값들을 가지고 사용된 검색방법의 유효성을 검사하는데 Recall/Precision방법이 이용되고 있다. 질의영상과 같은 군에 속하는 영상이 얼마나 검출되었는지를 검출된 영상에 기반 하여 계산하거나, 영상 군에 기반 하여 계산하는 방법들이다. 그러나, 검출되는 순위 값의 범위를 정하고, 그 범위 내에 속하는 만족하는 값의 개수를 세는 방법을 이용한다. 따라서 주어진 두 샘플의 전체적인 경향을 비교하지는 못한다. 본 연구에서는 순위를 이용하여 비교하고자하는 두 샘플의 순위들을 결합하여 순위를 매기고 각 샘플들에 매겨진 순위값들의 평균과 분산을 이용하여 각 샘플들을 전체적으로 비교할 수 있다. Retrieval effectiveness of content-based image is usually measured by "recall and precision" method. The method has disadvantages such that it depends on the number of considered images among retrieved ones. We propose the Wilcoxon rank test for measuring retrieval effectiveness instead of the recall and precision.

남윤자,이형숙,조영아 한국의류학회 1993 한국의류학회지 Vol.17 No.4
The Purpose of this study was to develop pattern drafting methods of the hip block and sleeve for female college students of 18 to 26 year-old. The study procedures and results were as follows 1. 313 female college students were measured, 17items were analyzed statisitcally. 2. New hip block and sleeve sloper were developed based on the result of the data analysis and fitting tests. 3. The sensory test was applied to evaluate the new hip block and sleeve sloper for female college student by comparing it with Japanese Bunka method sloper. According to statistical analysis of the result of 40items on the questionnaire, all the items showed significant difference(a∠=0.01) between the two, with the new pattern having higher scores. The new drafting method proved to be better fitted at all 40items, and to be comfortable.

The Purpose of this study was to utilize of CAD System in pattern making process for women's apparel. The automation by the use of CAD System provides the higher accuracy and efficiency in pattern making process. AccuMark 300 System was used, for this study. The results from this study were as follows 1. New size spec chart and grading pitch chart were developed based on the data analysis and fitting tests for female college students. 2. New jacket block was developed based on the torso length sloper. 3. Automatic grading of jacket block have been developed by creation and modification of grading rules of block pattern. 4. Pattern Design Systyem(P/D/S) were enabled to be constructed directly form a block pattern by modifications to existing styled pattern. 5. Original master pattern was generated by P/D/S menu option. 6. Production pattern added seam allowance, notchs was generated by P/D/S menu option. 7. Interative maker making process have enabled to save a wide range of time and space. 8. Measurement of garment by P/D/S measuring tools is to utilize in garment costing, quality control.

원격탐사에 사용되는 편미분방정식을 고속으로 풀기 위한 기법을 프로그래밍하고 성능을 향상시킬 수 있는 방법을 제시했다. 미지수가 30만개 이상되는 복소수(non-Hermitian) 행렬의 해를 구하는 프로그램을 작성했다. 이 프로그램은 C와 PVM에 기반을 두고 있다. 수렴속도를 향상시키기 위해 대각 스케일링을 이용했다. 통신속도의 개선을 위해 데이터 압축 기법을 이용했다. 수렴속도를 측정 제시함으로써 실제 문제 적용에 참고할 수 있다. Network-based computing with cluster of personal computers or workstations recently has become an important and successful technique. Network-based computing enables fast computation and resolves short of storage with computers on the desks. Cluster of inexpensive computers offers them aggregated computing power and storage to challenge very large-scale problems. Iterative solvers are used for the large sparse linear systems. Preconditioners accelerate the rate of convergence of the iterative solvers. However, parallelization accelerate the rate of convergence of the iterative solvers. However, parallelization of preconditioners is far from satisfaction so far. Thus, the simplest diagonal scaling is a good alternative for improved convergence and easy parallelization. In order to reduce communication overhead, a data compression technique is considered. Data communication time can be reduced at the cost of convergence rate. MATLAB simulation result is given in this paper. This method is effective to cluster of computers connected through slow networks.

The advent of neuroimaging technique has enabled the accurate diagnosis of structural abnormalities associated with intractable epilepsy. Among these, neuronal migration disorders(NMDs) or cortical dysplasias(CDs) involving cerebral cortex are increasingly recognized as a major cause of intractable epilepsy. CDs are expressed as variety of forms depending upon the time of injury to the developing nervous system. CDs are highly and intrinsically epileptogenic. It is crucial to completely resect the epileptogenic zone in focal CDs for better seizure outcome. Hemispherectomy or multilobar resection is preferred for hemimegalencephaly. Callosotomy can be chosen in the diffuse CDs who have intractable drop attacks. However, resective surgery can benefit the selected patients with diffuse CDs if localizing information persists.

The purpose of this study was to evaluate the value of briquet ash as a component of rooting media in Chrysanthemum morifolium. Various rooting media were made in mixture at different ratio and alone using sand, vermiculite and briquet ash as components of soil mixture. In order to investigate the effect of the particle size of briquet ash on rooting of stemcuttings, various particle sizes were used as rooting media. Rooting ratio, number of root and root length were examined to evaluate the effect of the various rooting media and the particle sizes of briquet ash. The important conclusions of this study are summerized as follows; 1. Briquet ash was better rooting medium than sand, but it showed more effective result when it was used in mixture with other rooting media. 2. The particle size of briquet ash as a rooting medium to produce a healthy vegetatively propagated plant showed the best result at 2-3mm.

Objectives : the purpose of this study is to report the improvement of HIVD patients with gait difficulty, who treated by M.S.T(Motion Style Treatment) Methods : the clinical study was done on 3 cases of patients with disc extrusion, whose walking ability was not improved after the admission in Ja-Seng Oriental Medicine Hospital for a week. we checked the walking time and NRS score after the treatment of M.S.T(Motion Style Treatment) each day. Results : the walking time increased after the treatment of M.S.T(Motion Style Treatment). Whereas NRS score decreased after the treatment of M.S.T(Motion Style Treatment). after 2-3 weeks of treatment, 3 cases of patients could walk more than 20 minutes.
