한글대장경 검색 시스템

한글대장경의 전산화 및 검색 시스템 개발은 세계에 우리 문화의 우수성을 널리 알리고, 우리 문화유산에 대한 국민적 관심을 높이며 해당 분야에 대한 효과적인 연구를 지원하기 위해 반드시 필요하다. 한글대장경은 고려대장경의 번역본으로 주로 한글로 기록되어 있지만, 원문의 이해를 돕기 위해서 다양한 한자가 사용되고 있다. 이러한 한자들은 본자(本字)와 뜻은 같지만 모양이 틀린 이체자(異體字)및 오자(誤字)나 탈자(脫字)로 간주되는 파자(破字) 등을 포함하고 있으므로 입력이나 저장 뿐 아니라 검색 관점에서도 여러 가지 문제점을 갖는다. 또한 인터넷이 널리 보급되면서 인터넷을 통한 문헌 검색이 증가하였지만 기존의 문헌 검색 시스템은 용어 검색, 색인 검색 등과 같은 단순한 검색만을 지원하기 때문에 사용자의 다양한 검색 요구를 충족시키기가 어려웠다. 본 연구에서는 한글대장경의 효과적인 입력과 저장을 위해 유니코드(unicode)를 사용하였고, 효율적인 검색을 위해 문서 구조를 XML로 정의하였으며, 결과내 검색과 히스토리 검색 등과 같은 다양한 검색 방법을 지원하는 웹 기반 한글 대장경 검색 시스템을 개발하였다.

Macrodactyly is one of the rare congenital anomalies of the upper extrimity. Fastt found 19 cases among 1476 patients with congenital anomalies of the upperextrimity, an incidence of 0.9 percent. The index finger is most commonly invlove. Multiple digits are involved two to and the index-long fingers. The authors recently experienced one case of macrodactyly involving the thumb and index finger in 20 year old female patient. The patient was treated with finger shortening using multiple corrective step ostectomies with the preservation of joints. We present this case with a review fo the literature.

Amelanotic melanoma is extremely rare and more aggressive than similarly staged pigmented lesion. It has been estimated that 2 percent of all melanoma is clinically amelanotic. The authors recently experienced 2 cases of amelanotic melanomas. An amelanotic melanoma of the left lower eyelid was widely excised, and reconstructed with the nasal mucochondral graft and Mustard cheek flap. Until 33month after the operation, no metastatic lesion was found and well being state. An amelanotic melanoma on the right buccal mucosa, in the other patients was widely excised and reconstructed with bilobed forearm flap. 10month later lung metastasis was noted.

이보영,한영근 명지대학교 산업기술연구소 2001 産業技術硏究所論文集 Vol.20 No.-

In this research, an architecture of Web based software system for performing physical validation of Automated Manufacturing Systems(AMS) in the design phase as well as in actual operation stages is presented together with implementation details. The proposed software system can be used for validating a general AMS model by modeling of facilities, facility layout, etc. The system has three major modules : 1) shape modeling module for defining basic solid primitives, 2) equipment modeling module for modeling physical configurations including kinematics of the facilities in AMS, 3) facility layout design module for constructing the physical layout model of AMS. The main results of this research include : 1) modeling method and virtual layout for facilities in AMS, 2) development of an web based software system using VRML, EAI and JAVA, 3) an application software system in the modeling of a Flexible Manufacturing System.

본 연구는 탄산가스화법에 의한 탄산칼슘 입자 제조 공정에 있어서, 탄산가스로 채워진 반응기에 수산화칼슘 슬러리를 분사하는 방법으로 탄산칼슘 입자를 제조하였다. 수산화 칼슘의 농도(0.25~1.0wt%), 분사압력(0.5kgf /㎠~1.5kgf /㎠) 및 반응기 온도(20℃, 28℃)의 변화에 따른 생성된 탄산칼슘을 관찰하였다. 수산화 칼슘의 농도가 비교적 높으면(0.75wt%, 1.0wt%), 생성물의 pH와 전도도는 높게 나타났다. 분사압력에 의한 탄산칼슘 제조의 변화는 분사압력이 높아질수록(1.5kgf /㎠), pH와 전도도는 높게 측정되었다. 그러나, 수산화 칼슘의 농도와 분사압력의 변화가 탄산칼슘의 입자크기, 형태, 결정구조에 영향을 미치지는 않았다. 반응기의 온도가 28℃에서 생성된 탄산칼슘은 1.0㎛이하의 칼사이트 상 입자가 제조되었으며, 20℃에서 생성된 탄산칼슘은 0.5㎛이하의 칼사이트 상 입자가 제조되었다. 반응기의 온도가 낮아질수록 탄산칼슘 입자의 크기가 작아짐을 알 수 있었다. For the preparation of calcium carbonate particles from aqueous Ca(OH)2 slurry, carbonation reaction of aqueous Ca(OH)2 slurry was carried out by spouting the aqueous slurry of Ca(OH)2 into reactor filled with CO2 gas. The concentration of Ca(OH)2 varies from 0.25wt% to 1.0wt%, nozzle pressure from 0.5kgf /㎠ to 1.5kgf /㎠, and reactor temperature were set at 20℃ and 28℃. With relatively high concentration of 0.75wt% and 1.0wt% of Ca(OH)2, pH and conductivity of product-stream were observed high value. High pH and conductivity were observed at high nozzle pressure of 1.5kgf /㎠. The concentration of Ca(OH)2 and nozzle pressure, however, did not change the particle size and shape of calcium carbonate synthesized by carbonation reaction. The reaction temperature affected particle size. At reactor temperatures of 28℃ and 20℃, the particle sizes were about 1.0㎛ and 0.5㎛, respectively. Crystal structure of calcium calcium carbonate was of calcite. When reactor temperature was lower, the size of calcium carbonate particle was smaller.

Objects : Event related potential(ERP) has been recently applied to examine the neurophysiological disturbance in attention deficit hyperactivity disorder(ADHD), particularly with regard to N100 &P300 which are known as one of ERP components closely linked with cognitive function. On the basis of these aspects, this study was designed to evaluate electrophysiologic cfaracteristics and its availability for diagnosis and treament of ADHD children by comparison of ERP between normal controls and ADHD children before and after metylphenidate(MPD) administration. Methods : We examined the topograhic auditory ERP and T. O. V. A. (Test of variables of attention), a standardized computerized visual continuous performance test following adminstration of stimulant drug, MPD 10㎎ in 13 ADHD children and compared these results with those of 11 normal controls. Results : The results were as follows : 1) Though the difference was not stastically significant(P=0.0548), N100 latencies seemed to be longer in ADHD children than in normal controls. N100 amplitudes also seemed to be larger in ADHD children than in normal controls(P=0.0629). 2) The P300 latencies significantly shortened after MPD administration when compared with those before MPD administration in ADHD group(P<0.01). 3) ADHD group performed significantly less well than normal controls in T.O.V.A.(P<0.05). And T.O.V.A. scores significantly improved after MPD administration in ADHD group(P<0.01). 4) The N100 & P300 latencies and the T.O.V.A. scores were significantly correlated before MPD administration in ADHD group(P<0.05). 5) The P300 latencies before MPD administration were significantly correlated with the amplitudes of changes of T.O.V.A. scores after MPD administration(P<0.05). Conclusion : It seemes that prolonged N100 latency of ADHD children can be regarded as a relatively enduring trait marker and that P300 latency may reflect attentional response ability along with therapeutic effect by stimulant.

There were studied on the chronic liver diseases, 38 patients for determination of lipoprotein fractions and serum lipids visiting to the Chunan Soonchunhyang Hospital. The results are obtained as followings: 1. The lipoprotein fractions in liver diseases were shown as:α-Lp 28.21±7.22%, pre-β-Lp 28.57±10.00%. β-Lp42.94±7.26%. 2. Pearson correlation between serum cholesterol and lipoprotein fractions was shown that chronic liver diseases are significant except β-Lp, and blood triglyceride with all lipoprotein fractions. 3. To compare between chronic liver diseases and lipoprotein fractions pre-β-Lp was only shown significantly positive. 4. From the above results chronic liver diseases were not determined from blood lipids and lipoprotein fractions.
