Purpose . To determine whether the significant relationship exists between radiographic appearance, whether it is unilocular or multilocular, and its corresponding clinical and histologic features by examining the odontogenic keratocyst clinically, radiologically and histologically. Materials and Methods : This study was conducted on 48 cases of odontogenic keratocyst from the files of Dental Hospital, Yonsei University for the years 1982 through 1995. Results and Conclusions : The mean age of patients was 30.5 years in the unilocular group and 35.5 years in the multilocular group. The male to female ratio was 1 : 1.06 in the unilocular group and 1 . 1.75 in the multilocular group. The chief complaint was swelling in both groups(unilocular 35.1%, multilocular 54.5%). In the occurrence site, the border of the lesion, the displacement and external root resorption of the adjacent teeth, there were no statistically significant difference between the unilocular group and multilocular group, but in the border type, there was statistically significant difference (x2-test, p<0.05). Two recurred cases were observed among 11 cases of odontogenic keratocyst. One was unilocular case and the other was multilocular case. (Korean J Oral Maxillofac radiol 2000; 30: 199-205)

김지혜,곽재용,임창열 대한내과학회 2003 대한내과학회지 Vol.65 No.4

악성 림프종에서 자궁 경부로의 전이는 드물지 않지만 자궁 경부의 원발성 림프종은 드물다. 우연히 건강검진에서 발견하게된 병기 IE로 진단된 자궁경부의 T-세포 림프종 1 예를 보고하고 올바른 진단과 분류가 이루어지면 적절한 치료를 할 수 있고 이로 인해 성공적인 예후를 보일 수 있음을 강조한다. Non-Hodgkin's lymphoma can involve the gynecologic tract, most often as a manifestatiion of systemic involvement. Primary lymphomas of the female genital tract are rare. Most involve the cervix rather than the uterine corpus. All of those previously reported have been B-cell lymphomas, with the exception of several case reports. Primary T-cell lymphoma of the uterine cervix is rare. We describe a rare case of primary cytotoxic T-cell lymphoma of the uterine cervix, Ann Arbor stage IE in a 55-year-old woman. The tumor, incidentally disclosed at gynecological examination, appeared as diffuse cervical enlargement with mucosal erosion. A biopsy was taken and showed diffuse infiltration of variable sized lymphoma cells. Neoplastic cells were positive for LCA, CD3, TIA-1 and consistent with cytotoxic T-cell lymphoma. She was treated with 3 cycles of cyclophosphamide, doxorubicin, vincristine, and prednisolone(CHOP). After chemotherapy, the patient was treated by pelvic external radiation therapy. At present, the patient is well and disease-free.

김지열 한국경상학회, 한국국민경제학회 2004 경제연구 Vol.22 No.1

지금까지 대부분의 연구들은 주식시장에 대하여 많은 확률모형들을 사용하여 주식시장에서의 주식가격이 합리적기대가설(rational expectation hypothesis)과 효율적시장가설(efficient market hypothesis)에 의해 임의보행과정(random walk process)을 따른다는 결론을 내고 있지만, 현실적으로는 주식시장에서의 이러한 임의보행과정이 실제로 주식시장의 움직임을 얼마나 정확히 설명하고 있는지에 대해서는 지금까지도 많은 의문이 제기되고 있다. 이러한 의문에 대해 본 논문에서는 우리나라의 주식시장에서 주식수익률과 주식수익률의 변동성에 관하여 장기기억효과(long-term memory effect)가 존재하는지, 그리고 장기기억효과가 존재한다면 종합주가지수(KOSPI:Korean Composite Stock Price Index)와 코스닥종합지수(Korea Securities Dealers Association Automated Quotations Composite Index)와는 어떤 차이가 있는지에 대하여 비교 분석하였다. 이러한 본 논문의 연구는 아직까지는 선행연구들을 찾기가 쉽지 않으므로, 본 논문이 주식시장의 성격 및 본질의 분석에 새로운 연구 방법으로서 하나의 대안이 될 수 있을 것이다. The studies until now are concluding that stock price in stock market follows random walk process by rational expectation hypothesis and efficient market hypothesis developing a lot of linear probability models that is many by judgment which time series data of stock market follow normal distribution by central limit theorem. However, random walk process in stock market has a lot of questions actually. Analyzed whether long-term memory effect exist in stock earning rate and volatility of stocks earning rate of Korea in thesis treating on this question. And if long-term memory effect exists. Korean composite stock price index and Korea securities dealers association automated quotations composite index analyzed what difference is.

RF무선모듈을 이용한 ECU 진단신호의 원격 계측

서지원,권대규,방두열,이성철 전북대학교 공학연구원 ( 구 전북대학교 공업기술연구소 ) 2003 工學硏究 Vol.34 No.-

In this paper, we present a remote measurement system for the wireless monitoring of ECU Sensor Signals of vehicle. In order to measure the ECU sensor signals, the interface circuit is designed to communicate ECU and designed terminal wirelessly according to the ISO, SAE regulation of communication protocol standard. A micro-controller 80C196KC is used for communicating ECU sensor signals. ECU sensor signals are transmitted to the RF-wireless terminal that was developed using the micro controller 80386EX, LCD, and RF-module. 80386EX software is programmed to monitor the ECU sensor signals using the Borland C++ compiler in which the half duplex method was used for the RS232 communication. The algorithms for measuring the ECU sensor signals are verified to monitor ECU state. At the same time, the information to fix the vehicle's problem can be shown on the developed monitoring software. The possibility for remote measurement of ECU sensor signals using 80386EX is also verified through the developed systems and algorithms.

목적 : 본 연구는 수근관 증후군의 발생위험이 높은 작업형태에 종사하는 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장과 목재소 근로자에서 근전도검사를 이용하여 수근관 증후군의 유병률을 조사하고자 하였다. 방법 : 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장 근로자 69명과 목재소 근로자 17명을 실험군으로, 관리직, 경리, 경비등 상지의 단순반복작업이 없는 근로자 28명을 대조군으로 선정하여, 작업적 및 병력조사, 이학적 검사와 근전도검사를 통해 수근관 증후군의 유병률을 조사하였다. 결과 : 수근관 증후군의 유병률은 육류 및 어류 가공 사업장과 목재소에서 각각 26.09 % (18명)와 29.41 %(5명)로 조사되었으며, 육류 및 어류가공사업장과 목재소 근로자를 '7년 이상과 미만의 작업기간'으로 층화하여 비교한 결과 '상지부위의 통증 호소 유무', 'Visual Analogue Scale(VAS: 총 10점) 4점 이상 여부', 'Tinel teat 양성 유무', 'Phalen test 양성 유무'는 모두 단기 작업근로자군에서 양성의 빈도가 증가되었고 '수근관 증후군 유무'는 장기작업근로자군에서 양성의 빈도가 증가되었다. 결론 : 육류 및 어류 가공 사업장과 목재소의 수근관 증후군 유병률은 각각 26.09 %와 29.41 %로 육류 및 어류 가공 사업장과 목재소는 1996년 OSHA가 지정한 바와 같이 위험한 작업요인이 있는 작업장으로 분류하여 관리되어야 할 것으로 생각된다. Objectives : This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method. Methods : Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS. Results : 18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms (complaint of upper extremities, Visual Analogue Scale ≥4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group(p<0.05). The prevalence of symptoms and signs were higher in short term workers(<7 years), but the prevalence of CTS was higher in long term workers(≥7 years). Conclusions : The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996

인터리브가 삽입된 CFRP 적층판의 층간파괴 인성평가

김지훈,강태식,한길영,김재열,심재기 한국공작기계학회 2001 한국생산제조학회지 Vol.10 No.4

In this paper, an investigation was performed on the dynamic interlaminar fracture toughness of CFRP(carbon fiber reinforcement plastics). Specimens used in this experiment are CF/PEEK laminated plates. In this experiments, Split Hopkin-son's Bar(SHPE) test was apply to dynamic and notched flexure test. The mode II fracture toughness of each unidirectional CFRP was estimated by the analyzed deflection of the specimen and J-integral with the measured impulsive load and reac-tions at the supported points. As an experimental result the vibration amplitude of [0˚_10/F_4/0˚_10] laminates appear more than that of [0˚_10/F_2/0˚_10] laminates for the J-integral and displacement velocity at a measuring point. Also, it is thought that the dynamic fracture toughness of two kind specimen(CF/PEEK) with the in crease of displacement velocity becomes great at a measuring point with in the range of measurement.
