위 MALT 림프종에서 다발성 림프절 전이로 오인된 동시성 림프절 결핵 1예

김성은,김규종,김도현,송준영,문대성,장리라,유찬희,문원,박무인,박선자,김영옥 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.2

28세 남자가 내시경적 점막절제술을 통해 저등급 위MALT 림프종으로 진단되었다. 병기설정을 위해 18F-FDG PET 검사를 시행하였고 우측 쇄골상부, 우측상/하부 기관주위, AP window 부위에 강한 섭취가 관찰되어 전이성 림프절로 판단하였다. 그러나, 우측 쇄골상부 림프절에서 시행한 절제생검에서 만성육아종성염증소견이 관찰되었고 조직의 결핵 중합효소연쇄반응에서도 양성 반응을 보였다. 2개월간 항결핵제의 사용 후 시행한 추적 컴퓨터단층촬영 검사에서 림프절 크기의 감소를 보여 최종적으로 위 MALT 림프종에서 광범위 림프절 전이로 오인된 동시성 림프절 결핵으로 진단되었다. A 28-year-old man was diagnosed as gastric MALT lymphoma in diagnostic EMR (endoscopic mucosal resection). He subsequently underwent an 18F-FDG PET. 18F-FDG PET showed intense multifocal uptake in right supraclavicular, right upper and lower paratracheal, and AP window areas that was considered radiologically to represent widespread metastatic lymphadenopathy. Excisional biopsy of a supraclavicular lymph node, however, revealed chronic granulomatous lymphadenitis with a positive reaction of Tb-nested PCR. After antituberculosis treatment for 2 months, a follow-up CT scan showed complete resolution of the lesions. Intense 18F-FDG uptake could be due to an infectious process such as synchronous tuberculous lymphadenitis. Therefore, this could mimic a malignant condition such as lymphoma with extensive lymph node metastasis due to a false-positive finding, which may lead to a misdiagnosis.

반응경로 모델링을 이용한 결정질암 지하수의 지구화학적 진화경로 예측

성규열,박맹언,고용권,김천수 韓國海洋大學校 附設 海洋科學技術硏究所 2002 硏究論文集 Vol.11 No.1

화강암지역에서 산출되는 국내 지하수의 화학조성은 주로 Ca-HCO_3와 Na-HCO_3, 형에 속하며, 일부는 Ca-(CI+SO_4) 또는 Na-(CI+SO_4)형의 특성을 나타낸다. 회장암 지역의 용출수는 Ca-HCO_3형에, 지하수는 Na-HCO_3 형에 도시된다. 빗물-화강암 반응에 대한 반응경로 모델리 결과는 초기 Ca-CI형에서 시작하여 Ca-HCO_3을 거친 후, 최종적으로 Na-HCO_3형으로 진화하는 경향을 보인다. 빗물-회장암 반응 역시 빗물-화강암 반응에서와 유사하게 진화되는 경향을 보이며, 모델링 결과는 현장자료와 잘 일치된다. 빗물-화강암/회장암 반응경로 모델링 결과, 반응이 진행됨에 따라 수소이온 활동도는 점차 감소(pH는 증가)하며, 양이온의 농도는 pH의 변화에 따른 모암을 구성하는 광물들의 순차적 용해, 2차 생성광물의 침전 및 재용해 등에 의해 다양한 농도변화를 보여준다. 빗물-화강암의 반응비에 따라 깁사이트, 적철석, 망간산화물, 카오리나이트, 실리카, 녹니석, 백운모, 방해석, 로몬타이트, 프레나이트, 아날심의 순으로 침전이 발생하며, 빗물-회장암의 반응에서도 이와 동일한 침전순서를 보이지만 실리카의 침전이 없고 아날심 대신 파라고나이트가 침전된다. 빗물-화강암 반응에서는 실리카가 가장 우세한 광물이며, 빗물-회장암 반응에서는 카오리나이트가 가장 우세한 광물이며, 전체적인 2차 생성광물의 침전량은 화강암보다 회장암 반응이 더 우세하다. The chemical compositions of groundwaters from the granite areas mainly belong to Ca-HCO_3 and Na-HCO_3 type, and some of these belong to Ca-(CI+SO_4) type. Spring water and groundwaters from anorthosite areas belong to Ca-HCO_3 and Na-HCO_3 type, respectively. The result of reaction path modeling shows taht the chemical compositions of aqueous solution reacted with granite evolve from initial Ca-CI type, via Ca-HCO_3 type, to Na-HCO_3 type. The result of rain water-anorthosite interaction is similar to evolution path of granite reaction and both of these results agree well with the field data. In the reaction path modeling of rain watergranite/anorthosite reaction, as a reaction is progressing, the activity of hydrogen ion decreases(pH increases). The concentrations of cations are controlled by the dissolution of rock-forming minerals and precipitation and re-dissolution of secondary minerals according to the pH. The continuous addition of granite causes the formation of secondary minerals in the following sequence; gibbsite plus hematite, Mn-oxide, kaolinite, silica, chlorite, muscovite (a proxy for illite here), calcite, laumontite, prehnite, and finally analcime. In the anorthosite reaction, the order of precipitation of secondary minerals is the same as with granite reaction except that there is no silica precipitation and paragonite precipitates instead of analcime. The silica and kaolinite are predominant minerals in the granite and anorthosite reactions, respectively. Total quantities of secondary minerals in the anorthosite reaction are more abundant than those in the granite reaction.

As an application area, it is one of rehabilitation machines of walking disable patients. First of all, the existing walking training robots were surveyed with aspect of types and specifications for the design of intelligent training robot. Several mechanisms were considered t o satisfy the strict requirements for a human friendly robot concept. An eletromechanical linear mechanism and a position control with force feedback are employed for efficient training method. The proposed control method has been applied t o the rehabilitation robot manipulator and is shown the control efficiency to retain a presetting reduced weight for two legs.

성일용,류성호,신상훈,김욱규,김종렬,정인교,변기정 大韓顎顔面成形再建外科學會 2003 Maxillofacial Plastic Reconstructive Surgery Vol.25 No.1

The authors analyzed retrospectively the 60 patients with ameloblastoma who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from MArch, 1990 to December, 1995. The results obtained were as follows: There were 26 males (43.3%) and 34 females (56.7%). The peak age of patients was the third decade (41.7%). The majority of cases occurred in the mandible 93.3%, especially in the angle region (91.1%). Eighteen of 60 patients (30.0%) were associated with an impacted tooth, by impacted 3rd molar teeth (16.6%), molar (10.0%), and premolar and canine (3.4%) in order., Fifteen of 60 patients (25%) were associated with an odontogenic cyst, by dentigenous cyst(13.3%), odontogenic keratocyst(8.4%), and radicular cyst(3.3%) in order. Radiographically, there were 32 unilocular types(54.2%) with average age of 24.9±10.8 years, 14 multilocular types(23.7%) with average age of 35.7±17.7 and 13 mixed types(22.0%) with average age of 41.4±15.8. Histopathologically, there were 42 follicular types(70.0%) with average age of 33.7±15.1 years and 18 plexiform types(30.0%) with average age of 26±14.6. Conservertive treatment was performed in the 33 patients(55.0%) and their average age was 25.2±13.9 years and radical treatment in the 27 patients(45.0%) and their average age was 39.3±41.8. Overall recurrence rate was 10%. A consistent correlation between the age of the patient and the radiographic or histologic type of mandibular ameloblastoma was observed. There was a tendency for ameloblastomas of the follicular type to show a multilocular or mixed appearance and for those of the plexiform type to show a unilocular appearance.

섬망 치료에 있어서 Quetiapine과 Risperidone의 효과 비교

사공정규,정성원 대한생물치료정신의학회 2011 생물치료정신의학 Vol.17 No.2

본 연구에서는 최근에 개발된 비전형 항정신병 약물인 quetiapine이 섬망의 치료에 효과가 있는지와 비전형 항정신병 약물인 risperidone과 효과의 차이가 있는지 평가하고자 하였다. 총 71명의 환자가 본 연구 대상에 포함되었고 CGI, K-DRS, K-DRS-R-98, K-MMSE를 평가 도구로 하여 치료 전과 치료 일 주일 후 측정한 전체 점수를 비교하였다. 부작용에 대한 평가도구로는 ESRS 점수를 치료 전후에 비교하였다. 연구 결과 두 군 모두에서 일주일 후 측정한 CGI-S, K-DRS, K-DRS-R-98, K-MMSE에서 통계학적으로 유의한 차이를 보였다. 두 군 간 치료전후의 통계학적인 차이는 보이지 않았다. 부작용은 두군 모두에서 나타나지 않았다. 이번 연구에서 quetiapine은 섬망 환자의 치료에 있어 risperidone과 동등한 효과를 보이고 부작용이 적어 섬망 환자의 치료에 안전하게 사용할 수 있을 것으로 기대된다. Objectives:It has been shown that risperidone, an atypical antipsychotics, has effectiveness for treatment of delirium as good as haloperidol and has less side effects than haloperidol. Quetiapine also has less extrapyramidal side effects and has effectiveness for treatment of delirium. The aim of this study was to investigate whether quetiapine is effective for the treatment of delirium compared with risperidone. Methods:All subjects(71 patients) were randomized to receive either risperidone(35 patients) or quetiapine(36 patients) with fixed dose at the first day of treatment. Then, all subjects received either medications with flexible doses according to judgement on clinical status of patients. The effectiveness was evaluated using Clinical Global Impression-Severity(CGI-S), Korean version of Delirium Rating Scale(K-DRS), Korean Mini Mental Status Examination(K-MMSE), and Korean version of Delirium Rating Scale-Revised-98. Results:There was no significant difference between both groups in the baseline K-DRS, K-DRS-R-98, K-MMSE and CGI scores. At the seventh day of the treatment, K-DRS, K-DRS-R-98 and CGI scores were significantly improved from the baseline both in the quetiapine and risperidone treatment group. Conclusion:Quetiapine is effective for treatment of delirium.

리눅스를 기반으로 한 홈오토메이션 서버의 구현

성한용,김규칠,방철원,김용석 江原大學校 産業技術硏究所 2002 産業技術硏究 Vol.22 No.B

It becomes common to use computers to control electronic devices and security facilities in newly constructed buildings and house. There are many home application devices in the market which can be controlled by computers. But they are expensive and managed by specialized companies. This paper is focused on personal computers which are available in most homes and can be used to control home electronic appliances and home security facilities. We implemented a home automation server based on Linux. The standard parallel port of personal computer is used to connect sensors and actuators. Therefore, the cost of the server is very low. Moreover, the server is connected to Internet and anywhere we can control and monitor the home security facilities and home automation systems.
