Asphaltene 증가에 따른 Asphalt의 物性變化

洪元杓,金熹洛 忠南大學校 産業技術硏究所 1986 산업기술연구논문집 Vol.1 No.2

To investigate the effect of asphaltene content on the change of physical properties of modified asphalt, the experiments were performed by changing amounts of additive, catalyst, heating temperature, heating time and amount of air. The results from the experiments are as follows: 1. The contents of asphaltene observed from the chemical treatment of straight asphalt as a raw material increased in the order of catalyst use of FeCl₂and P₂O , addition of polymer and heating temperature. However the effect of air blowing was negligible. 2. As a result of increased asphaltene contents in straight asphalt, the decreasing rate of penetration was observed to be nearly propertional to the increasing rate of softening point.

홍금원,임재수,서희철,임해창 고려대학교 컴퓨터과학기술연구소 2001 JOURNAL OF COMPUTER SCIENCE & ENGINEERING TECHNOLO Vol.3 No.-

본 논문에서는 한국어의 특성을 고려한 용례 검색 시스템을 제안한다. 제안된 시스템은 직접 용례 검색과 색인 기반 용례 검색을 제공한다. 직접 용례 검색에서는 원시 말뭉치에서 한글 음절 단위의 검색뿐만 아니라 한글 자소 단위의 검색이 가능하며, 색인 기반 용례 검색에서는 어절, 형태소, 그리고 체계화된 품사정보를 이용한 검색이 가능하다. 검색속도 및 색인된 파일의 크기는 실험을 통하여 최적화 한다. 사용자는 검색된 용례로부터 연산 및 정렬 과정을 거쳐서 보다 정확하게 선별된 용례를 얻을 수 있다. 본 시스템을 통해 얻어진 용례 정보는 사전 편찬 등의 한국어 연구의 기초 자료로 활용할 수 있으며, 말뭉치를 기반으로 한 다양한 분야에서 활용할 수 있을 것이다. In this paper, we propose the concordance system considering the characteristics of Korean. The proposed system provides two kinds of retrieval method: direct access retrieval and index based retrieval. In direct access retrieval method, it is possible to retrieve examples using grapheme-based query as well as syllable based query. In index-based retrieval method, it is possible to retrieve examples using eojeol, morpheme, or part-of-speech. The speed of the system and the size of the indexed file is optimized through several experiments. Users can acquire the exact and selective examples from previously retrieved items by filtering and/or sorting. The linguistic information acquired by the system can be utilized as basic data for Korean Linguistic research such as lexicography and it can be used in various application fields based on corpus.

The purpose of this study is a development of releasing agent which is used for slate curing. The required conditions for preparing of releasing agent which is used for slate curing are as follows ; 1) The releasing agent is required to have a good affinity with water. 2) It is required to be stable against hydration heat which is generated in the course of curing process. 3) It is required to have a film forming property during curing stage. 4) It is required to have a low evaporation rate. Several experiments such as surface tension, evaporation rate, and economic analysis, were proceeded on the materials which were satisified with the above descriptions. From the experimental experiments, the optimum parts ratio of the releasing agent was confirmed as "light oil : methylene chloride : rice bran oil (3 parts) + Stearic acid(2 Parts) = 200 : 20 : 5"

홍승철,김현집,정희원,조병규,한대희,지제근,최길수,심보성 대한신경외과학회 1986 Journal of Korean neurosurgical society Vol.15 No.2

Authors report 10 cases of intracranial inflammatory granulomatous lesions which were identified on CT scan and proven pathologically after surgical excision. They were composed of three cases of tuberculoma, three cases of degenerated cysticercus, two cases of healed abscess and two cases of non-specific inflammatory lesions. Most patients were children or young adults. Seizure was the most frequent presenting symptom. All cases had characteristic CT findings in common a small nodular or ring-like lesion with strong enhancement surrounded by irregular-shaped low density area. Surgical exploration is of value in that specific diagnosis would not be possible with clinical and radiological findings only.

Objectives : To evaluate the absorbed and effective doses of spiral and computed tomography for the dental implant planning. Materials and Methods : For radiographic projection, TLD chips were placed in 22 sites of humanoid phantom to record the exposure to skin and the mean absorbed dose to bone marrow, thyroid, pituitary, parotid and submandibular glands and nesophagus. Effective dose was calculated, using the method suggested by Frederiksen et al.. Patient situations of a single tooth gap in upper and lower midline region, edentulous maxilla and mandible were simulated for spiral tomography.35 axial slices(maxilla) and 40 axial slices (mandible) with low and standard dose setting were used for computed tomography. All the radiographic procedures were repeated three times. Results : The mean effective dose in case of maxilla was 0.865 mSv,0.452 mSv,0.136 mSv and 0.025 mSv, in spiral tomography of complete edentulous maxilla, computed tomography with standard mAs , computed nomography with low mAs and spiral tomography of a single tooth gap (p〈0.05). That in case of mandible was 0.614 mSv, 0.448 mSv, 0.137 mSv and 0.036 mSv, in spiral tomography of complete edentulous mandible, computed tomography with standard mAs, computed tomography with low mAs and spiral tomography of a single tooth gap (p〈0.05). Conclusions : Based on these results, it can be concluded that low mAs computed tomography is recommended instead of spiral tomography for the complete edentulous maxilla and mandible dental implant treatment planning.

무증상으로 발견된 담낭-담관 누공을 동반한 Mirizzi 증후군 1예

홍진희,전태주,서지영,서동대,오태훈,신원창,최원충,신은아,김기환 인제대학교 2009 仁濟醫學 Vol.30 No.-

Mirizzi's syndrome is a rare complication of the gallstone disease, characterized by narrowing of the common bile duct (CBD) due to chronic extrinsic compression of an impacted gallstone in the cystic duct or the neck of the gallbladder. The impacted gallstone may erode into the bile duct, causing cholecystocholedochal fistula. The patients generally have history of repeated attacks of jaundice and abdominal pain. But there is no report about asymptomatic Mirizzi syndrome with cholecystocholedochal fistula which were found incidentally. So herein we present our clinical experience with a case of asymptomatic Mirizzi syndrome with cholecystocholedochal fistula in a young female.

The object of this study is to analyze the dynamic characteristic of lateral damper for the railway vehicle. The vibration characteristics are studied from eigenvalue analysis for critical velocity, and frequency analysis for the effects of the damper. Critical velocity of the model passenger car is found to be a) 20 m/s for damping force of 0 kg s/m, b) 64 m/s for damping force of 1,500 kg s/m, c) 60∼74 m/s for damping force of 730∼2,500 kg s/m. In high speed running, damping force should be decreased for high critical velocity. Lateral damping force should be greater than 730 kg s/m for stable running.
