과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

불어 시청각 교재 및 교수법 개발

金旭熔,朴仁善,李輝子 亞洲大學校 1985 論文集 Vol.8 No.-

Nous avons essaye, dans cette etude, d'effectuer une comparaison sommaire des methodes audio-visuels entre De vive voix et Sans frontieres. De vive voix, paru en 1972, est une methode audio-visuel inspiree des recherches de la linguistique structurale. Cette methode invite a apprendre par coeur les dialogues comme modeles de langue par des exercices structuraux pour atteindre a l'objectif de communication. L'essentiel de la morphologie et de la syntaxe du francais est etudie dans ce texte selon une progression serree. La grammaire a souvent la forme d'un mecanisme grammatical a force des exercices structuraux. Mais ces exercices sont peu interessants, quelquefois trop enuyeux pour les etudiants meme s'ils donnent les notions de base de syntaxe. Par contre Sans frontieres est une methode qui a essaye de faire la synthese des approches structurales et communicatives. Du cote du structuralisme, on remarquera les dialogues audiovisuels, des exercices structuraux, de la grammaire explicite, des listes de vocabulaire. Du cote du fonctionalisme, on trouvera beaucoup de documents authentiques, jeux de role, exercices de creation. Cette methode nous fait entrer dans la realite francaise avec les documents authentiques, avec les vocabulaire actuel de tous les jours et nous fait connaitre les registres de langues francaises propres a chaque categorie sociale. Sans frontieres est une methode vraiment adapte au cours de conversation. Elle invite a faire parler, instruit en amusant et fait enfin arriver a communiquer en langue francaise.

SF_6 절연파괴에 미치는 도전성 파티클의 영향

구자윤,이방욱 漢陽大學校 工學技術硏究所 1996 工學技術論文集 Vol.5 No.1

In this work, particle effect on the breakdown in pressurized SF6 was systematically investigated using Cu particle fixed on the parallel electrode monitoring system. For this experiments, various size particles were prepared and D.C Voltage and Lightning Impulse voltage were applied to the system as a function of gas pressure from 1 atm to 5 atm. At D.C test, it was revealed that particle length could affect the breakdown voltage seriously and corona stabilization effect could influence the breakdown voltage at some critical pressure and streamer corona was main discharge mechanism on the breakdown in SF6. At L.I test, breakdown voltages were affected depending on the the polarity of applying impulse voltage. It was noticed that the negative polarity could reduce the insulation strength much greater than the positive polarity and breakdown voltage could not be raised by increasing gas pressure above the critical value.

We intended to determine the usefulness of window operation for adult hydrocele repair. We reviewed medical records of 132 patients from January 1995 to June 1998 with primary hydrocele and evaluated complications and recurrence rates of eversion and/or excision, plication, and internal drainage technique. Recurrence rate was highest in internal drainage technique as 85.2%, and those of eversion and/or excision and plication technique were 1.3% and 4%, respectively. Complication rate was highest in eversion and/or excision technique, and lowest in internal drainage technique. Although complication rate was lowest in window operation, this operation could not be successful due to high recurrence, and we suggest that this operation should be abandoned for hydrocele repair.

We intended to know whether all of the patients with asymptomatic microscopic hematuria should be urologically investigated routinely. We reviewed the medical records with asmptomatic microscopic hematuria from January 1995 to December 1997. Urological studies included intravenous urography or ultrasonography, urine cytology, cystoscopy and biopsy, urine AFB smear and culture and urine PCR for AFB. The age with patients ranged from 9 to 74 years(mean age: 39.7 years). Benign diseases were found in elderly patients and patients with high degree of hematuria, but there was no patients who had urological malignant disease. According to the results, we suggest that follow-up with urine cytology is sufficient to younger patients or low degree of hematuria with asymptomatic microscopic hematuria.

한국인 모발과 내부장기조직간 Cd, Hg, Pb 및 Zn함량의 상호관련성

유영찬,이상기,양자열,김기욱,이수연,정규혁 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.1

In order to study the relationships between trace element concentrations of hair and internal organs, autopsy samples of hair, liver, kidney cortex, kidney medulla, heart, lung, spleen, cerebrum, testis and bone from 162 Korean subjects were analyzed for Cd, Hg, Pb and Zn by inductively coupled plasma atomic emission spectrometry. High significant positive correlations were found between the Cd concentration in hair and bone and Pb in hair and lung. Hair Hg levels were highly significantly correlated with organ Hg levels in the liver, kidney cortex, kidney medulla, heart, lung, spleen, cerebrum, testis and bone. And hair Zn levels were highly significantly correlated with organ Zn levels in the kidney cortex, kidney medulla, spleen, testis and bone.

This study was conducted to measure and compare the salivary cotinine concentration between smokers and nonsmokers, and to investigate the effect on the exposure to environmental tobacco smoke(ETS) with housewives, living on an apartment of Korea. Saliva samples were taken from all volunteers and salivary cotinine was analyzed by a developed radioimmunoassay(RIA) method. The median salivary cotinine levels were 52.8±12.6 ng/ml and 44.6± 9.7 ng/ml in male smokers and in female ones, respectively, and they were 4.3±2.1 ng/ml and 2.9±3.1 ng/ml in male nonsmokers and in female ones, respectively. In addition, average salivary cotinine levels were 3.8±2.7 ng/ml in housewives from smoking homes and 2.4±2.4ng/ml in ones from nonsmoking homes. Results obtained from the analysis of salivary cotinine demonstrate that smokers had a significantly higher concentration of salivary cotinine than nonsmoker. But, there was no significant difference in the salivary cotinine concentration for housewives living in apartment between with smoking husband and with nonsmoking husband.

여성 하부요관석환자에서 무마취하 요관경하 배석술

박영호,송윤섭,임용순,김영호,이남규,구자현,서병욱,김민의,전윤수 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.2

Although ureteroscopy(URS) has been used widely to remove ureteral calculi, there is an argument against the belief that anesthesia or admission is needed for URS. We evaluated the experience of URS without anesthesia in female patients. From September 1997 to July 1998, URS was performed in 31 female patients without anesthesia. EHL(Electrohydraulic Lithotripsy) was used in 21 patients with impacted or large stone over 5mm. All patients were given oral antibiotics for 3 days and follow-up KUB was taken to confirm successful removal of the stone one week after the procedure. Successful treatment was defined as complete removal of the stone or residual fragments less than 2mm. Overall success rate was 96.7%(30 cases among 31 cases). All but one patient tolerated with analgesia through the entire procedures. There were only minimal complications such as mild flank pain and hematuria. So, we recommend that non-anesthetic ureteroscopic removal of stone as the first choice for treatment of lower ureteral stones in female based on the minimal morbidity, high success rate and low cost.
