        오재규,박선주,유태현 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.3

        Granular cell tumors are relatively uncommon benign laryngeal lesions, especially in children. The granular cell tumor can occurs everywhere in our body. Half of all granular cell tumors occur in the head and neck, with a third of these occuring in the tongue. The larynx is relatively uncommon location, accounting for approximately 7% to 10% of all reported cases. Typically, the most common presenting symptom is hoarseness, with some patients also presenting stridor, hemoptysis, dysphagia. But the tumor may be asymptomatic and be discovered only incidentally during a routine examination. Confirmative diagnosis should be made histopathologically and supported by immunohistochemical staining using S-100. Treatment of a granular cell tumor is complete excision with an attempt to maintain normal structures. We experienced a 14-year-old woman with laryngeal granular cell tumor, which involves the epiglottic lower margin. She was successfully treated with complete excision under laryngomicroscopic dissection. So we report it with a review of literatures.

        Park, Hong Yul,Choi, Gi Hyuk,Yoon, Hyeong Sik,Lee, Seunghoon,Woo, Sun Hee,Shim, Hyung Sik,Oh, Kyoung Hwan,Cho, Young Min,Yong, Sang Soon,Lee, Sang Gyu,Heo, Haeng Pal 대한원격탐사학회 1998 International Symposium on Remote Sensing Vol.14 No.1

        Korea Aerospace Research Institute (KAKI) is developing a Korea Multi-Purpose Satellite I (KOMPSAT-1) which accommodates Electro-Optical Camera (EOC), Ocean Scanning Multi-spectral Imager (OSMI), and Space Physics Sensor (SPS). The satellite has the weight of about 500kg and will be operated on the 10:50 AM sun-synchronized orbit with the altitude of 685 km. The satellite will be launched in 1999 and its lifetime is expected to be over 3 years. The main mission of EOC is the cartography to provide the images from a remote earth view for the production of 1/25000-scale maps of KOREA. EOC collects 510 - 730 nm panchromatic imagery with the ground sample distance(GSD) of 6.6 m and the swath width of 17 km by push broom scanning. EOC also can scan ±45 degree across the ground track using body pointing method. The primary mission of OSMI is worldwide ocean color monitoring for the study of biological oceanography. It will generate 6 band ocean color images with 800 km swath width and 1km GSD by whiskbroom scanning. OSMI is designed to provide on-orbit spectral band selectability in the spectral range from 400 nm to 900 nm through ground command. This flexibility in band selection can be used for various applications and will provide research opportunities to support the next generation sensor design. SPS consists of High Energy Particle Detector (HEPD) and Ionosphere Measurement Sensor (IMS). HEPD has missions to characterize the low altitude high-energy particle environment and to study the effects of radiation environment on microelectronics. IMS measures densities and temperature of electrons in the ionosphere and monitors the ionospheric irregularities at the KOMPSAT orbit.

        박선규,반성수,우영제,김규용,김무한 忠南大學校 産業技術硏究所 1998 산업기술연구논문집 Vol.13 No.1

        The fluidity of high flowing concrete can be affected by numerous parameters which characterize either the cement or the admixture. The reactivity of a cement as determined by its chemical compositions (especially its C₃A content), its fineness and its content in sulfates and alkalies obviously plays a key role in rheology of high flowing concrete in fresh state. Specific properties of high range water reducing AE agent used to enhance the workability of high flowing concrete also exert important influence. The purpose of this experimental study is to investigate and analyze the effect of cement and high range water reducing AE agent in fluidity, setting, compressive strength of high flowing concrete. As a result, we found that fluidity of high flowing concrete is affected greatly by kind of cement and high range water reducing AE agent, also, there is harmonic character between high belite cement and polycarbonic acid high range water reducing AE agent.

        오재규,박선주,유태현 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.3

        Background and Objectives : Hemorrhage is one of the most common complication after tonsillectomy. Despite of many various efforts, it still remains unsolved problem to many otolaryngologist. Because so many factors are related to postoperative bleeding after tonsillectomy, so we tried to see the postoperative hemorrhage rate in relation to various parameters. Material and Methods : A retrospective study on patients who had underwent tonsillectomy in Wallace Memorial Baptist Hospital for 6 years from January 2002 to December 2007. Parameters such as sex, seasons of year, age distribution, tonsil size, previous tonsillitis history and anesthesia type were considered. Results : Overall hemorrhage rate was 2.6%. Postoperative hemorrhage was common in adult males with incidence of 4.5% and most of them was secondary hemorrhage. In age distribution, the incidence was high in the group of 16~30 year. Bleeding was common in autumn, grade II tonsil and increased when the history of tonsillitis was frequent, and local tonsillectomy was better in terms of bleeding compared with tonsillectomy under general anesthesia. but there was no statistical significance. Conclusion : To reduce the incidence of postoperative hemorrhage, perioperative education and complete bleeding control during operation is important for high risk patients.

      • 유통정보시스템의 효율적 구축방안에 관한 연구 : 부산·대구지역을 중심으로 Focusing on the Sales Business in Pusan-Taegu

        李奎煥,朴善泰,金香蘭 대구산업정보대학 1998 논문집 Vol.12 No.1

        This study aimed first to correctly understand informationalization of distribution, that is POS System, EDI, EOS, and distributing VAN, second to observe the present condition and preceeding examples of construction of informationalization of distribution in our country and to execute analysis of corroborative evidence regarding informationalization of distribution centered on distributing companies in Pusan and Taegu districts, third to grasp the impeding primary factors when informationalization is built up, and fourth to present effective building up lans of informationalization of distribution in Pusan and Taegu districts which will be the foundation of informationalization of distribution in the distributing business circles. The writer studied, for the method of study, by dividing into theoretical study, research portion of the present condition and preceeding examples of building up informationalization of distribution, and analysis of corroborative evidence. For the theoretical study portion and analysis examples, the study method by documentary records was applied, and domestic and foreign books, theses and periodicals related to the informationalization of distribution were consulted. For the analysis of corroborative evidence, the writer studied by questionaires regarding opening of distributing markets, distriubuting environment and distributing information system of the distributing market by the retail dealers as its objects, and selected research by questionaires to collect information by personally visiting each company. About 15 universities and junior colleges related to the distributing industry in our country produce about 1,280 of fundamental manpower related to distrribution every year, and a portion of large-sized distributing companies established and are managing even inter-company colleges, but it is the real situation that these are not sufficient in quality and quantity. In order to cultivate manpower specialized in distribution, the industry, universities and government, forming a trinity, should cope with the matter jointly, and especially, the government level should newly establish subjects of study related to the distribution drastically and political and financial support should be necessarily followed. Also, if POS system is induced, as the source of tax revenue is completely exposed, compared with those companies which do not induce POS System, they will suffer disadvantage, so preferential treating method is necessary in case of application of valued added tax or income standard. The customary practice of dealing without data harmful to normal commercial transaction order and against equity is pointed out as the most fundamental problem point being held by the distributing business circle in our country. For the sake of effective building up the distributing information system, the source making rate shall be raised, the ratio of domestic made instruments of POS System shall be increased, by developing EOS System which can be connected with manufacturing companies, POS System shall be utilized effectively by connecting with the management information system of the whole enterprises, EIS (Executive Information System) and various data base, and shall be connected with EOS with other components of distributing channel and EOS and EFT (Electronic Fund Transfer) system shall be connected through EDI or VAN. Such distributing information system can accomplish composite distribution information systematization, so it can promote greatly the management power not only of distributing business but manufacturing business.

      • Bisthmus 제재와 항생제의 복합 투여가 Helicobactor pylori 박멸과 재발에 미치는 영향

        김선주,황성규,박상흠,이문호 순천향대학교 1994 논문집 Vol.17 No.4

        위점막내에 존재하는 Helicobacter pylori는 소화성 궤양의 발생과 재발에 중요한 인자로 인식되고 있으며, bisthmus, metronidazole, amoxicillin을 포함하는 3제 병합요법을 시행하면 H. pylori균의 박멸에 유효하고 소화성 궤양 재발 빈도를 낮출 수 있다고 한다. 그러나 3제 병합요법은 부작용 발생율이 높아 치료 실패의 주원인이 되고 있다. 이에 저자등은 H. pylori 양성인 소화성 궤양환자에서 H₂ 길항제 투여와 함께 3제 병합요법을 시행하였고, 또한 비교적 약제 부작용이 많은 metronidazole을 제외한 이제 병합 요법을 시행하여 H₂ 길항제 단독 투여한 대조군과 6개월간 추적하여 균의 박멸및 재발 여부를 비교 관찰하였다. 대조군은 Nizatidine을 8주간 투여하였으며 치료 1군은 nizatidine(150mg 하루 2회 복용)을 8주간 투여하고 첫 2주간은 TDB(240mg 하루 2회 복용), amoxicilline(500mg 하루 4회 복용) 투여하였다. 치료 2군은 nizatidine(150mg 하루 2회 복용)을 8주간 투여하고 첫 2주간은 TDB(240mg 하루 2회 복용)과 amoxicilline(500mg 하루 4회복용) metronidazole (250mg thrice a day)을 투여하였다. 치료 8주후 치료 1군은 53%에서, 치료 2군은 100%에서 균이 음전되었으나 대조군은 1예도 음전되지 않았다. 치료 2군의 13%에서 약물에 의한 부작용이 관찰되었다. 치료 6개월 추적 검사시 대조군은 모두 H. pylori 감염이 지속되었으며 치료 1군에서는 63%에서 재발하였으며, 치료 2군에서는 15%에서 재발하였다. 대조군에서는 소화성 궤양(위궤양 1명, 십이지장 궤양 4명)이 5명에서 재발하였으나 치료군에서는 재발이 없었다. H. pylori박멸된 환자에서의 항 H.pylori 항체(IgG)가는 치료 6개월에 치료전의 40%로 감소한 반면, 대조군의 항체가는 변화가 없었다. 이상의 결과로 H₂ 길항제(nizatidine)을 metronidazole 750mg/day, TDB 480mg/day, amoxicillin 2.0gm/day를 2주간 투여하면 약제에 의한 합병증이 비교적 적고, Helicobacter pylori 박멸과 재발 방지에 효과적이며 혈청 H. pylori 항체(IgG)의 추적 검사는 항 H. pylori 치료후 균박멸의 추적검사에 유용함을 알 수 있었다. It has recently been recognized that Helicobacter pylori is a important factor in the development and the recurrence of peptic ulcer diseases. Several studies has been shown that the eradication of Helicobacter pylori is associated with considerable reduction in the the rate of recurrence of peptic ulcer. Triple therapy including bisthmus, amoxicillin, metronidazole is known to be useful in the eradication of Helicobacter pylori, but relatively frequent side effects are a major problem. This study was performed to evaluate the clinical course and the efficacy of triple therapy with H₂ blocker and bisthmus plus amoxicillin therpy with H₂ blocker in the eradication and the recurrence of Helicobacter pylori at 8 weeks and 6 months of treatment. Forty five patients with peptic ulcer disease with a positive urease test of the gastric mucosa were enrolled and assigned to receive H₂ blocker (nizatidine 150mg twice a day) for 8 weeks(control group), tripottasium dicitrato bismuthate 240mg twice a day and amoxicillin 500mg four times a day for 2 weeks, nizatidine for 8 weeks (treatment group Ⅰ), tripottasium dicitrato bismuthate 240mg twice a day and amoxicillin 500mg four times a day, metronidazole 250mg thrice a day for 2 weeks, nizatidine for 8 weeks(treatment group Ⅱ). H. pylori was eradicated in 53% of treatment group Ⅰ, 100% of treatment group Ⅱ, none of control group after 8 weeks of treatment. Helicobacter pylori infection is recurred in 63% of of treatment group Ⅰ and 15% of treatment group Ⅱ. Side effects were recorded in 3 patients(2 patients on treatment group Ⅱ, 1 patient on treatment group Ⅰ), but it were minor side effects. No patients on treatment groups recurred peptic ulcer disease, while 5 patients on control group. Anti-H. pylori antibody IgG remained constant in bacteria positive control group, but in patients in whom H. pylori had been eradicated serum antibody titers fell significantly at 6 months of treatment. In conclusion, triple therapy including a low dose metronidazole with nizatidine is effective on the eradication of Helicobacter pylori infection and reduced the rate of side effects. Bisthmus and amoxicillin with nizatidine is not effective on the eradication and the recurrence of Helicobactor pylori infection. Serologic tests for H. pylori are reliable means of monitoring success of eradication of H. pylori.
