        홍수민 ( Su Min Hong ),김유선 ( You Sun Kim ),문정섭 ( Jung Seop Moon ),김진남 ( Jin Nam Kim ),오명기 ( Myoung Ki Oh ),권선옥 ( Sun Ok Kwon ),정성연 ( Seong Yeon Jeong ),홍성우 ( Seong Woo Hong ),강윤경 ( Yun Kyung Kang ) 대한소화기학회 2013 대한소화기학회지 Vol.61 No.2

        Background/Aims: Rectal carcinoid tumors can be resected with endoscopy, and it is important to assess their prognostic factors. We evaluated the potential of Ki-67 expression as a prognostic factor in rectal carcinoid tumors. Methods: We retrospectively reviewed the medical records of 37 patients with rectal carcinoid tumors who got endoscopic resection from January 2001 to January 2011 at Inje University Seoul Paik Hospital. We analyzed their endoscopic and histologic findings, Ki-67 expression, clinical outcome, and prognosis. Results: The mean age (±SD) of the patients was 56.3±10.7 years, and the male : female ratio was 3.6:1. The mean tumor size was 0.5±0.4 cm, 33 patients showed grade 1 tumors (89.2%) and the average Ki-67 expression was 0.7±1.2%. Thirty five patients underwent endoscopic mucosal resection, and two required endoscopic submucosal dissection. Eight patients had positive margins after resection, but no cases of lymphovascular invasion were identified. The median follow-up duration was 21.4±25.4 months, and no recurrences were observed. Conclusions: In low grade rectal carcinoid tumors which are lack of central depression on colonoscopy, the expression of a molecular marker of malignant potential, Ki-67, was low. Therefore, endoscopic resection seemed to be a safe and effective treatment for these tumors.

        석면에 장기간 노출된 퇴직한 수리조선업 근로자의 폐영상 : 단순흉부촬영 및 고해상전산화단층촬영 소견과 그 유병률 Lung and Pleural Diseases Prevalence on Chest Radiograph and HRCT

        김기남,김정일,,이기남,정갑열,김준연 大韓産業醫學會 2006 대한직업환경의학회지 Vol.18 No.2

        목적: 장기간 석면에 노출되었던 퇴직한 조선소 근로자에서 단순흉부촬영과 고해상 CT소견 및 그 유병률을 알아보고자 하였다. 대상 및 방법: 수리조선소에서 배관공 또는 영선반에서 근무한 후 퇴직한 근로자 18명을 대상으로 하여 후전면 및 측면 단순흉부촬영과 고해상 CT를 시행하였다. 이들은 모두 조선소에서 사용하는 단열재 사용 작업 중에 석면에 노출되었다. 결과: 단순흉부촬영에서 총 18례 중 12례(66.7%)에서 흉막병변이 관찰되었다. 흉막플라크의 위치는 횡경막 단독으로 비후된 경우가 5례로 가장 많았으며, 외측흉벽 흉막플라크의 두계는 a가 3례, b가 1례에서 보였고, 길이는 1이 4례, 2가 1례에서 보였다. 흉막플라크를 가진 12례 중 2례는 미만성 흉막비후를 동시에 보였다. 흉막플라크의 석회화는 횡경막에서만 4례 관찰되었다. 석면과 관련된 폐실질병변이 의심되는 소견은 관찰되지 않았다. 고해상 CT에서는 16례(88.9%)에서 흉막비후가 관찰되었으며, 위치는 척추 주위 13례, 횡경막 11례 등이었다. 동반된 석회화는 7례에서 보였다. 두께는 1 mm부터 1cm까지 이었고, 길이는 2cm부터 47cm이상까지 매우 다양하였다. 3명(16.7%)에서 흉막비후 근처의 하폐 기저부에 흉막하 곡선이 나타나는 석면폐증의 초기 소견이 보였다. 결론: 장기간 석면에 노출된 근로자의 석면 관련 흉막병변의 유병률이 매우 높아 장기적인 추적검사가 필요하다고 사료된다. Purpose: To determine imaging findings among retired workers who were long-term exposed to asbestos. Lung and pleural diseases prevalence were studied on chest radiograph and HRCT. Materials and Methods: Eighteen workers who were long-term exposedto asbestos occupationally in shipyards were examined by chest radiographs (PA and lateral view) and HRCT (high-resolution computed tomography). Results: In 12of 18 subjects (66.7%), asbestos-related pleural abnormalities were evident in diaphragmatic, lateral chest wall and costophrenic angle of the pleura on chest radiographs. The thickness of pleural plaques at the lateral chest wall varied. Diffuse pleural thickening was evident in 2 workers. Parenchymal abnormalities were not found on chest radiographs. On HRCT, pleural thickening wasobserved in 16 of 18 subjects (88.9%), in the areas of juxtavertebral, diaphragmatic, anterior, lateral, mediastinal and fissural pleura. Curvilinear subpleural lines representing early parenchymal asbestosis were found in the lower posterior lung in three of 18 subjects (16.7%). Conclusions: In long term asbestos-exposed workers, the asbestos-related pleural disease was 66.7% on chest radiographs and 88.9% on HRCT. The authors suggest that this group should be followed up periodically

        목적 : 국내에서 발열을 동반한 호중구감소증이 있는 악성 종양환자에게 경험적 항생제로 베타락탐계 항생제와 아미노배당체의 병합요법의 사용이 일반적이다. Cefepime은 광범위 항균 작용을 가지고 있어, 그람 음성균 뿐만 아니라 그람 양성균에 대해서도 우수한 효과를 나타낸다. 재료 및 방법: 발열을 동반한 호중구감소증이 있는 악성 종양환자를 대상으로 무작위, 공개, 비교 연구를 시행하였다. 대상 환자를 무작위로 cefepime 단독요법군과 ceftazidime 및 tobramycin 병합요법군으로 나누어 투여하고 각각의 임상적 효능과 안전성을 비교하였다. 구강및 인후 점막염이 있는 환자에서 분리된 녹색 연쇄알 구균에 대한 항생제 내성 정도를 조사하였다. 결과 : 대상환자 89명 중 CA 투여군이 48예(53.9%), CT 투여군이 41예(46.1%)이었다. 발열의 유형별로 MDI는 18예(20.2%), CDI는 9예(10.1%), UF는 62예(69.7%)로 두 군 간에 차이가 없었다. CA 투여군과 CT 투여군의 임상적 호전률은 시험약 투여 후 2-4일째 각각 91.7%, 85.4% (P=0.31), 치료 종료 시 각각 91.7%, 100% (P=0.15)로 두 군간에 유의한 차이가 없었다. 치료 종료 시 CA 투여군과 CT 투여군의 세균학적 소실률은 모두 100%로 두 군간의 유의한 차이가 없었다(P=0.78). 점막염이 있는 환자로부터 녹색 연쇄알 구균이 분리된 경우는 25예(28.1%)이었으며, 분리된 녹색 연쇄알 구균은 penicillin, ceftriaxone, cefepime, vancomycin에 모두 감수성을 보였다. 약제 관련 이상 반응의 발생 빈도도 두 군간에 유의한 차이가 없었다. 결론 : 발열을 동반한 호중구감소증이 있는 악성 종양환자의 경험적 항생제로서 cefepime 단독요법은 ceftazidime 및 아미노배당체의 병합요법만큼 효과적이고 안전하였다. Background : Broad-spectrum antibiotic therapy has been recommended as an empirical regimen in cancer patients with febrile neutropenia. Cefepime is a fourth generation cephalosporin with good activity against both gram-positive cocci and gram-negative bacilli. Materials and Methods : To compare the efficacy and safety of cefepime alone with ceftazidime plus tobramycin as empirical regimen for adult cancer patients with febrile neutropenia, a randomized, open label, comparative trial was performed. If the patient showed clinical improvent 72 hours, antibiotic could be changed to oral ciprofloxacin. Clinical and microbiological responses were determined at 72 hours and at the end of therapy. To investigate the antimicrobial resistance of viridans streptococci, swab cultures were obtained from throat in all enrolled patients and antimicrobial susceptibility tests were performed by using microdilution method according to the NCCLS. Results : A total of 89 patients were enrolled. Forty-eight patients received cefepime alone (CA), and 41 patients received ceftazidime plus tobramycin (CT). Demographic and baseline clinical characteristics were similar in both groups (P>0.05). The initial clinical success rate at day 2-4 in group CA (91.7%) was similar with that in CT group (85.4%) (P=0.31). At the end of therapy, the final clinical success rate in CA group (91.7%) was similar to that in CT group (100%) (P=0.15). In 18 patients, with microbiologically defined infections, the eradication rate was 100% in both groups. Adverse events including liver dysfunction (21.3%) and renal dysfunction (2.2%), were similar in both groups (P=0.87). Viridans streptococci were isolated from the throat cultures in 25 cases, and all of these strains were susceptible to penicillin (MIC_(90) 0.12 ㎍/mL), cefepime (1 ㎍/mL), and vancomycin (0.12 ㎍/mL). Conclusion : Efficacy and safety of cefepime monotherapy was comparable to the combination of ceftazidime and tobramycin. It could be used as an alternative empirical regimen for treating cancer patients with febrile neutropenia.

        폐쇄성 수면 무호흡 환자의 측모 두부방사선계측사진 및 치아모형 연구

        정미라,황상희,남기영,김종배,권오원 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.3

        폐쇄성 수면 무호흡증이란 수면도중 주기적으로 호흡이 멈추는 증상을 말한다. 상악과 하악이 후퇴되어 있거나 하악이 작으며 수평적으로 기도 폭경이 좁고 혀가 후방에 위치하는 등 폐쇄성 수면 무호흡 환자의 전후방적인 악골 및 연조직 특성에 대한 평가는 많았으나 치열 및 악궁에 대한 평가가 부족하여 폐쇄성 수면 무호흡증 환자의 골격적 특징과 악궁의 폭경과 구개깊이와 수면무호흡지수와의 상관관계를 알아보고자 하였다. 계명대학교 의과대학 동산의료원 수면클리닉에 수면장애를 주소로 내원한 환자 중 수면다원검사와 측모 두부방사선계측사진과 치아모형이 갖추어진 38명의 남자를 대상으로 하여 치아모형과 측모 두부방사선계측사진, 수면무호흡지수와 체질량지수를 비교하였다. 수면무호흡지수와 악궁의 횡폭경, 구개깊이, 수직피개량 및 수평피개량과는 상관관계가 없었으며 수면무호흡군에서 상기도 폭경은 좁고, 하기도 폭경은 넓은 경향이 있었다. 수면무호흡지수와 상기도 폭경은 미약한 음의 상관관계를 가졌으나 하기도 폭경은 미약한 양의 상관관계를 가졌고, 수면무호흡지수가 클수록 하악 하연으로터 설골까지의 거리도 멀었다. To evaluate the cephalometric and dental characteristics of obstructive sleep apnea (OSA) patients, 23 OSA patients and 15 control, non-OSA, patients who visited the Sleep Disorder Clinic Center, Keimyung University were investigated. Patients who suffered from apnea-hypopnea episodes over 10 times per hour were diagnosed as having OSA after polysomnograph testing. Impressions were taken with alginate. Cephalometric radiographs were taken at maximum intercuspation. The dental cast measurements, including transpalatal width, intercanine width, intermolar width and palatal depth did not differ between the control and OAS groups and did not have a positive correlation with the apnea-hypopnea index (AHI). Upper airway width was statistically narrower than the control group. Upper airway width had a low negative correlation with AHI, but, lower airway width had a low positive correlation, and, the higher the AHI score, the longer the mandibular border to hyoid distance.

      • 餘暇活動 參加의 社會的 要件 : 椿川市內 主婦들을 中心으로 Like above results based on researches about social in women's leisure activity in Chunchon city can be derived

        鄭淸子,夫基源,朴南煥 江原大學校附設 體育科學硏究所 1984 江原大學校附設體育科學硏究所論文集 Vol.- No.9

        S. E. S. is one of the elements in resolving participation for individual leisure activities and is static leisure activity rather than dynamic activity. It is probable that that women try to participate in leisure activity dynamically, their husbands, however, have initiative in women's activities. However, it is certain that social elements in the step from family of orientation to family of procreation cannot be found apparently. This(research) remains a few questionable problems. One of them is to explain several elements except for choice of leisure activities and effective factors in participation in leisure activity; resolving participation in activities not only for women but all of the members in family.

      • 수용성 절삭유제 내에서 Saccharomyces cerevisiae와 Escherichia coli의 성장에 관한 연구

        정광진,최희영,김장규,원성호,김남기 成均館大學校 科學技術硏究所 1992 論文集 Vol.43 No.2

        The water-soluble cutting oil was used in the type of the mixture of additive lubricant, surfactant, etc., as the organic nutrients, with water. Therefore it was easy to be affected by microbials ; they brought the bad odor by putridity, decreased the cutting property, and destroyed the emulsion phase. In the study using cells, Saccharomyces cerevisiae and Escherichia coli, we studied the effect of concentration and dilution ratio on the growth of cells and the cell growth rate, the pH variance and the change of oil's concentration. The results obtained in this experiment were as follows : 1) The result of test dilution ratio (water:oil) vs. cell growth was that by using E. coli, the growth was better in this order in emulsion type (sample 1) 50:1 > 30:1 > 100:1, and in the soluble type (sample 2) the order was 100:1 > 50:1 > 30:1. The effect of the cutting oil's concentration on the Saccaromyces cerevisiae's was less in this order 100:1 < 50:1 < 30:1 ; the maximum growth was occurred at 100:1. 2) In sample 1 by using E, coli, pH range was changed from 9.5 to 8.0 and refractive index(the cutting oil's concentration) was changed from 1.3327 to 1.3318. And in the test using S. cerevisiae, pH range was varied from 9.5 to 6.2 and refractive index was changed from 1.3330 to 1.3310. In sample 2 by using E. coil, pH was changed to 8.9 and refractive index was changed from 1. 3315 to 1.3313 and in that of using S cerevisiae, pH was changed to 8.1 and refractive index was decreased from 1.3355 to 1.3340.
