Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

색채 선별기 영상보정 시스템 구현

이재균,김춘식,이채욱 대구대학교 정보통신연구소 2010 情報通信硏究 Vol.7 No.1

우리가 주식으로 하고 있는 쌀이나 곡물들은 대부분 색채 선별기(color sorter)를 이용하여 선별하고 있다. 이러한, 색채선별기의 성능을 좌우하는 것은 선별력이라 할 수 있고, 선별력을 좌우하는 가장 중요한 요소는 광학 선별 센서이다. 곡물을 선별하는 방식으로 포토센서 선별방식과 CCD 센서 선별방식으로 나눌 수 있다. 대부분의 시스템에서 CCD 센서 선별방식이 포토센서 선별방식보다 많이 사용되는데 그 이유는 많은 양의 원료를 한꺼번에 선별할 수 있기 때문이다. 기존 CCD 센서 색채선별기는 일정한 선별구역을 나누어 구역마다 영상신호 레벨차를 구별하여 선별신호를 보내는 데, CCD 센서의 동작에 있어서 보정 전의 영상신호는 렌즈로 기인한 프레임을 중심으로 하여 바깥쪽으로 구부러져 마치 배가 튀어 나온듯한 배럴(barrel)왜곡 현상이 발생한다. 본 논문에서는 마이크로 컨트롤러를 사용하여 이미지 센서에 검출된 왜곡 영상에 대한 보정을 할 수 있는 CCD 영상 보정회로시스템을 구현하고자 한다. We are doing to the food or corn and are assorting a color sorting machine. To decide the performance of such color sorting machine is the sorting technique. Most important element which controls the sorting technique is an optical sorting sensor. The method to assort the corn has the photo sensor method and CCD sensor method. CCD sensor is used much in most systems than a photo sensor method, because, it can select raw materials of much quantity at once. Existing CCD sensor color sorter sends sorting signal distinguishing a video signal level car in area dividing fixed sorting area, as long as relationship video signal hides by lens before revision in action of CCD sensor, because ship bounds hors awry laying stress on frame, one barrel (barrel) distortion phenomenon happens. In this paper, we proposed the CCD image compensation system using micro controller which can be compensate for detected distortion image in image sensor.

In order to clarify the difference between the physiological activities of resistant rootstock, Pyrus betulaefolia (P.b) and susceptible one, Pyrus serotina (P.s) in response to physiological disorder, so called "Yubu fruit", this experiment was conducted. Pear trees cv. "Isipseki" used in experiment were grafted on P. betulaefolia and P. serotina, and then they cultivated in pot during 3 years. The results obtained are as follows: (1) The rootstock P.b absorbed more water and cations(Ca??, Mg??, K?) than P.s, and the difference of absorption between two rootstocks was great in early growing season. (2) Concerning to ratio between absorbed cations, Ca??/K? and Ca?//Mg?? were high in P.b, but Mg/K did not shown these tendency. (3) Superior absorbing power in P.b rootstock was revealed greatly in volcanic ash than sand soil. (4) According to soil dryness, absorption of water and cations was decreased significantly regardless of rootstocks. (5) As compared with xylem of roots in both rootstocks, the hole size of vessels was larger in P.b than P.s.

Deep burns of the face & lips often lead to scarring and contraction of the circum-oral tissues with a marked reduction in the size of the oral aperture. Such burns most commonly caused by electrical contact, for example, children sucking electric plugs, or as a result of chemical burns and the exposture to flame. Once having burns, burned tissue may contract and reduce considerably the size and mobility of the mouth ; therefore bring up the resultant functional disturbance, verbal difficulty, even disgestive difficulty, and poor appearance, which fall into difficulty in social acceptability, caused by burns. In our department, 2 patients who were complain of functional limitations and esthetic problem owing to scar contracture, were visited, and we treated this microstomia with scar excision, graft and flap technique, and postoperative intensive physical therapy. We obtained relatively favorable results, thus report this cases with literature review.

김영재,장근선 선문대학교ㆍ중소기업기술지원연구소 2000 선문공대 연구/기술 논문집 Vol.5 No.1

전세계적으로 CFC계열 냉매의 사용이 규제됨에 기존 냉매들을 대체할 수 있는 새로운 대체냉매의 개발이 활발하게 이루어지고 있다. 대체냉매의 사용은 필연적으로 냉동공조기기의 시스템특성을 변화시키고 이에 따라 변화된 시스템특성에 적합한 새로운 운전조건이 필요하게 되었다. 증발기, 응축기와 같은 열교환기는 에어컨의 소용화, 고효율화 및 저소음화의 모든 요소에 직접적으로 영향을 주므로 대체냉매용 또는 신형 공조기의 개발 및 설계기술에 필수적인 고려 사항이다. 공조기기의 열교환기 설계나 열교환기의 공기측 전열 성능을 해석하기 위해서는 습공기의 성질을 알아야 한다. 이러한 습공기의 성질들은 습공기선도(Psychrometric chart)를 이용하여 구할 수 있다. 본 연구에서는 습공기선도의 물성치 및 습공기선도를 이용하여 공기측 전열량을 예측할 수 있는 프로그램을 Visual C++와 Visua Fortran을 이용하여 개발하였다. It has been a world-wide trend to seek a new refrigerant alternative due to worldwide regulations on the use of the conventional CFC’s The alternative refrigerants necessarily changes the system characteristics of refrigeratior equipment As a result, it is necessary to develop new operating conditions suitable to the changes of system characteristics In general, the refrigeration system mainly consists of various standard components such as the evaporator, the condenser, the compressor, and the expansion device. Among them, the heat exchanger such as the evaporator and the condenser is an important component for developing new refrigeration equipments using alternative refrigerants. Generally, the physica properties of the wet air have to be konwn for designing heat exchangers and calculating the air-side heat trnasfer rate These physical properties of the wet air can be obtained from the psychrometric chart. In this study a computer program. that estimate the properties of the wet air and air-side heat transfer rate, has been developed using Viusal C++ and Visua Fortran.

악성종양과 감별이 어려웠던 악안면 영역의 감염질환에 대한 치험례

서재훈,김영균,여환호 大韓顎顔面成形再建外科學會 1995 Maxillofacial Plastic Reconstructive Surgery Vol.17 No.3

It is very difficult to differentiate the malignant tumor from the maxillofacial infections that have unclear cause, severe indurated swelling, pain and nonresponsiveness to antibioitic treatment and incision and drainage. Incisional biopsy, CT, and MRI examination may not distinguish between infection and a malignant tumors. And then, the clinicians can make a mistake that they perform a unnecessary radical surgery because of inaccurate diagnosis. We present three case reports of maxillofacial infectious disease with diagnosis process, treatment and differential diagnosis. The infectious disease were not resolved with antibiotic and surgical drainage. The progression of clinical sign and radiographic, indings of these disease were masqueraded as malignant tumors.
