In this paper, we introduce an Automatic Hypertext Generation System for text document written in korean. Also, we made a parser which divide text document into a set of cards. This cards were configured hierarchical structure. Each card in the hierarchy is associated with the formal identifier already present in the conventional version. After these steps were completed. we addressed our most pressing research concerns-indexing and retrieval. Each card can be retrieved by user's natural language query and graph traversal And, we believe that radiology picture archiving and communication systems will provide a valuable impetus for the implementation.

김명관 서울保健大學 1995 論文集 Vol.15 No.1

We have attempted to develop a medical patient records management system for 1,000 bed hospital model. A Medical Patient Record is configured by Doctor's order. Nusing Progress Note, Doctor's Progress Note, Intern's White Note, several inspection sheets, charts and etc. The Management system for patient records is archiveing and retrieval system about several type medical data. The computer networking and multimedia communication are the state of the art techniques in computer science area. The most popular server system in Internet is WWW(World Wide Web). Therefore, HTTP(Hyper Text Transport Protocol) was investigated for replying for queries. Finally, the relationship between UMLS(Unified Medical Language System) and our system will be discussed.

저가의 랜(LAN)과 PC환경을 이용한 의료화상 검색시스템에 관한연구

김명관 서울保健大學 1996 論文集 Vol.16 No.1

The Picture Archiving and Communication System(PACS) concept originated in radiology. The goal of PACS is to develop computer hardware and software which would enable electronic access and storage of patient data and images. But the cost is very high. We have attempted to develop a low cost PACS. Therefore, Web and Ethernet were investigated for solve this problem.

遠隔探査技法을 利用한 金海平野의 地表環境分析

金又寬,曺明姬 慶北大學校 1991 論文集 Vol.51 No.-

Various techniques of remote sensing are applied to identify types of land cover on the Kimhae Delta Plain from its Landsat TM inage of November 21, 1984. The techniques used here are evaluated in terms of their effectiveness and limitation in land cover classification. And then examinations are made of distributional characteristics that individual land covers have over the area. The rssults of an effectiveness evaluation of remote sensing techniques in this study are as follows. 1. A Visual analysis of individual spectral bands shows that targets in the area are more easily distinguished in one band than in another one. 2. An analysis based on false color composite images shows that the combination of bands 4-3-2 is most effective for classifying large-scale land covers like manmade structure or vegetation ect. And band combinations of 5-4-3, 5-3-2, or 5-4-2 are complementarily needed for a detailed classificaton of vegetation or man-made structure. 3. Density slicing is found a useful technique to classify in detail water or soil of different quality. Especially, its application to the band 5 image shows a better result than that to any other bands. But density slicing is found inadequate for the area which has many terrestrial elements of subtle spectral difference mixed wildly. 4. A Supervised classification using the maximum likelihood method indicates that : 1) the band combination of 5-4-3 proves most effective in the land cover classification, which results in 16 different classes. 2) supervised classification provides more distinguishing accurate and interpretable results, and 3) agricultural produces such as green onion, radish/cabbage, and parsley are readily recognize, and for the first time it is found possible to distinguish between fresh and salt water, and between non-saline and saline soil. Distributional characteristics of individual land covers are as follows. 1. The Kimhae Delta Plain has an individual vegetable produce to concentrate over some specific areas. Green onion forms a large patch throughout Myungho-Do especially by covering its beach ridge of sandy soil in the coastal delta. Radish/cabbage centers around the natural levee along the Chukrim-Gang and the Pyongchon-Gang. And parsley forms a large patch in the Pombangri area. 2. Non-saline soil is located in paddy fields of the upper delta and its surrounding area, whereas saline soil is found in those of the lower delta. 3. The Pyongchon-Gang, Chukrim-Gang and Macdo-Gang are of fresh water, which have underwater facilities for protection againt salt water reflux in their mouths. In the year of 1984 when the Naktong River did not have such a facility, salt water appeared far inland along its main stream.

유해 사진 탐지 도구 개발에 관한 연구

인터넷의 확산과 더불어 무수히 많은 음란물 사이트들이 양산되고 있다. 음란물을 방지하기 위한 도구들은 주로 사이트 주소를 가지고 이루어지는 경우와 사이트 내의 키워드를 사용한 방지가 대부분이다. 본 논문에서는 우선 색상분포에 따른 영상 분류가 실시간 처리 및 유해 영상 인식에 효과적 임을 보였다. 또한 기계학습 기법을 사용하여 유해 영상을 직접 구분하는 알고리즘을 제안한다. 약 2000 장 이상의 사진을 가지고 학습 및 분류를 시행했으며 상관계수, 베이지안, NN기법들을 복합적으로 사용 하여 2 단계 구분 기법을 적용한 결과 80% 에 가까운 높은 정확도와 대상 사진에 영향 받지 않는 안정도를 보였다. In this paper, we propose a Internet filtering tool which allows parents to manage their children's Internet access, block access to Internet sites they deem inappropriate. The other filtering tools which like Cyber Patrol. NCA Patrol. Argus, Netfilter are oriented only URL filtering or keyword detection methods. Thease methods are used on limited fields application. But our approach is focus on image color space model. First we convert RGB color space to HLS (Hue Luminance Saturation). Next, this HLS histogram learned by our classification method tools which include cohesion factor, naive baysian, k-nearest neighbor. Then we use voting for result from various classification methods. Using 2.000 picture, we prove that 2-layer voting result have better accuracy than other methods.

The purpose of this research is to verify the relationship between the changes of the operating cycle and the changes of the stock price in the firm. If the reduction of the operating cycle means a positive result of successful business reengineering of an enterprise whereas the increase in the operating cycle has an immense impact on stagnant sales and inefficient inventory management, a negative correlation is expected to exist between the operating cycle and the stock price. Following is a summary of this research ; First, the changes in operating cycle or the ratio of cash cycle and the stock price has a negative correlation. This finding is evident within industries of electronics, transportation equipment and machineries, but not so obvious in other industries. Secondly, the following findings are established for the operating cycle, cash generation capability, and the stock price ; ·As the capability of cash generation increases, the stock price increases. ·As the operation cycle extends, the stock price and the capability of cash generation decreases. Third, a negative correlation is found in the relationship among the raw material, work-in-progress, finished goods and account receivable collection and is maintained between the stock price and each respective factor. And finally, when the operating cycle is extended a negative correlation is found between the stock price and the operating cycle whereas when it is shortened such negative correlation is not found. This indicates only a negative impact on the operating cycle is relevant to the stock price.

In recent years the amount of sequencing has increased tremendously, especially due to the introduction of automated DNA sequencing. PCR is principal method for the synthesis of templates for DNA sequencing. Consequently, the need for PCR cleanup for template preparation has increased. Already, many PCR purification kits are marketed. This DNA purification kits uses most glass membrane or silica gel, So, can do rapidly efficient purification by simple miniprep. But, efficiency of purification kits is different according to manufacturer and is very expensive. Therefore, we compare the homemade Diatomaceous earth column with major manufacturer's spin column methods for DNA purification. As a result, we found that the homemade Diatomaceous earth column method resulted in equal or better yields relative to the commercial purification kits.

The purpose of this study is to develop an internet based physical distribution management system for electronic commerce. It includes an internet shopping mall which has multi-supply centers and a decision agent. And, it has supporting systems such as a mailing system, a bulletin board system, etc. for inter-communication with customers. Appling this system, it is expected that not only the administrator could operate physical distribution efficiently but also customers could do their better shopping via internet.
