실시간성을 제공하는 신뢰적인 다중 그룹통신의 설계 및 구현

윤미연,신용태 崇實大學校 生産技術硏究所 2001 論文集 Vol.31 No.-

In this thesis, it is proposed and designed a group communication API using Objected-Oriented. It is divided as two services, group membership services and delivery services. The group membership services provide dynamic group management. And the Delivery services provide data transmission management. This API has reusability, scalability, flexibility as using Objected-Oriented. And also it is very easy to add, modify and delete later on. Moreover, due to encapsulate of low-level entity, it provides convenient user interface.

표면을 열처리한강은 어떤 깊이에 대하여 일반적으로 경도의 변화층을 가지고 있다고 잘 알려져 있다. 이것은 기계적 특성이 다른 두 재료를 붙여 놓은 것과 같은 이종재료간 접합구조물로 생각할 수 있을 것이다. 열처리 후에는 재료의 성질이 변화하는 것으로 알려져 있고, 경도 및 인장강도 등이 변화하는 물성치의 예이다. 그런데 재료의 탄성계수와 푸아송의 비가 열처리 후에 달라지는지에 대한 연구 결과는 찾기가 어렵다. 본 연구에서는 SM45C강 환봉의 열처리한 후에 탄성계수와 푸아송 비의 변화에 대하여 실험적으로 규명하고 열처리 경화층을 이종재료의 층으로 고려하여 탄성 응력해석해야 할지를 한 가지의 해석모델을 설정하여 검토하였다. In general, it is well known that the surface heat-treated steel has a certain depth of hardened layer with different hardness. The surface heat-treated steel can be thought as a dissimilar structure bonded by two materials which have different mechanical properties. Material properties are changed by heat treatment and hardness, tensile strength etc. are examples of changing material properties. To author's knowledge, it is difficult to find out the results of study for elastic modulus and Poisson's ratio of heat-treated materials. In this paper. Elastic modulus and Poisson's ratio for the heat-treated SM45C steel rod were investigated experimentally. Elastic finite element analysis was also performed to investigate that the surface heat-treated hardened layer must be considered as a dissimilar structure.

김용태,엄민식,이석영,신관희,서정원,윤석중,이상철,김원재 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.2

연구목적: 진성 복압성 요실금의 치료법으로서 복강경을 이용한 Burch 수술을 타수술법과 비교하여 그 유용성을 알아보고자 하였다. 대상 및 방법: 진성 복압성 요실금을 주소로 본원 비뇨기과에서 수술을 시행받은 44명의 환자를 수술법별로 분류하여 수술법에 따른 성공률, 수술 시간, 입원 기간 및 합병증의 빈도를 비교 분석 하였다. 결과: 전체 환자에서 수술 성공률은 86.4% 였으며 이들 중 복강경을 이용한 Burch 수술군에서는 성공률이 100% 이었다. 복강경을 이용한 Burch 수술군은 타수술군에 비하여 입원 기간이 짧았다. 복강경을 이용한 Burch 수술군은 합병증이 매우 경미하였으며 전체 환자의 31.8%에서 단기간의 배뇨곤란을 호소하였으나 장기간의 배뇨곤란은 없었으며 슬링 수술군에서는 3례(16.7%)에서 심한 절박성 요실금을 호소하였다. 결론: 복강경을 이용한 Burch 수술은 높은 치료 성공률과 낮은 합병증의 빈도를 나타내어 진성 복압성 요실금의 치료에서 매우 우수한 수술법으로 사료된다. Purpose: We performed this study to investigate the usefulness of laparoscopic Burch colposuspension as a treatment of genuine stress incontinence compare to other anti-incontinence operation. Materials and Methods : We analyzed success rate, operation time, admission day, and complication rate of various anti-incontinence operations in 44 genuine stress incontinence patients who have been received operation in our hospital. Results : Overall success rate was 86.4%, but laparoscopic Burch coposuspension showed 100% success rate. Laparoscopic Burch colposuspension required shorter admission day compared to other anti-incontinence oparations. Complication rate was lower in laparoscopic Burch colposuspension group. Short-term voiding problems were identified in 31.8% of total patients but 3 patients(16.7%) who have received sling operation complained severe urge incontinence. Conclusion : Laparoscopic Burch colposuspension is considered as an effective surgical method for genuine stress incontinence due to high success rate and low complication rate.

N-benzoyl과 N-benzylaniline류의 광화학

박용태,이익형,윤달호 慶北大學校 自然科學大學 1986 自然科學論文集 Vol.4 No.-

Several N-benzoylanilines were prepared by adding aniline into the hot substituted benzoyl chlorides for photochemical reaction studies. N-benzylanilines were also synthesized by reacting appropriated benzyl halides with anilines. N-benzoyl or N-benzylanilines in the deaerated benzene solution or acetonitrile-water solution in presence of hydroxide were irradiated with 100W-mercury arc lamp. N,N-dibenzoylaniline and N,N-bis-(2-chlorobenzoyl)-aniline gave photo-Fries type reaction products effectively. N-(o-chlorobenzyl)aniline gave photo-cyclized reaction products in the base condition and photo-Fries type reaction products in the deaerated benzene solution.

An Ac-type Plasma Display Panel (PDP) operating with Ne-Ar(0.1%) Penning mixture gas is fabicated. The characterics of the panel with electrodes covered with thin and thick dielectric layers are studied. The brightness of the Neon-orange light emitted by the panel measured as function of applied voltage and frequency. As an application, a graphic display system equipped with PDP showing still and moving pictures is made.

김태현,김상욱,최지훈,송우건,윤경호,김진아,최석채,나용호 圓光大學校 醫科學硏究所 1999 圓光醫科學 Vol.15 No.2

Dieulafoy's ulcer is an uncommon lesion that usually presents wih massive bleeding. Although it has been observed, for the most part, in the stomach, it has also been identified in the small bowel and colon A 35-year-old male presented with lower gastrointestinal bleeding, which was found to be caused by a Dieulafoy's ulcer in the rectum. Diagnosis was by colonoscopy. (This lesion was injected initially with endoscopic injection of a solution of hypertonic saline solution with 1/10,000 epinephrine followed by bipolar electrocoagulation.) No further bleeding has occurred with follow-up 6 months. We report one patients with extragastric Dieulafoy's lesion in the rectum.

정인용,정현우,김태환,진수일,윤택구 대한방사선 방어학회 1988 방사선방어학회지 Vol.13 No.1

국내 原子力 産業의 施設增大로 放射線核種汚染의 가능성이 날로 증가되고 있음에도 불구하고 종사자 및 인근주민에 대한 診療對策에 관한 연구가 전무한 실정에 있어 이에 대한 기초자려마련의 일환인 應急處置方案을 수립코자 58CoCl2 1μCi를 마우스 (NIH-(GP))의 腹腔內에 投與한 후 CoNa3 DTPA 8.4mg/0.2ml saline, CoNa3 DTPA 8.4mg/0.2ml saline, saline 5ml등을 각각 投與하였으며, cobalt의 全身殘存量, 體內分布 및 尿內 含有된 量을 測定하기 위해 投與 後 4, 8, 12, 48시간, 그리고 7일에 MCA의 Ge-detector로 放射能을 計測하였고, 또한 각 實質臟器內 殘存된 cobalt의 放射能을 測定하기 위하여 각 group당 6마리의 마우스를 屠殺解體하여 測定하였던바 다음과 같은 결론을 얻었다. CoNa3 DTPA 處置群에서는 汚染된 放射性 cobalt의 全身殘存率의 減少 및 排泄率 增加에 유효한 效果가 있었으며, system contamination에 대한 방어효과는 CoNa3 DTPA, CoNa3 DTPA 그리고 saline 順으로 유효하였다. 결론적으로 본 실험결과로 볼 때 放射性 cobalt의 體內汚染에 대한 緊扱措置는 CoNa3 DTPA와 다량의 물을 동시에 投與함으로써 體內汚染된 放射性 cobalt의 排泄을 促進시킬 것으로 사료된다. In case of the acute intake of radionuclide, an early medical treatment may be necessary, but the little is established the procedures to decontaminate the victims of internal contamination in Korea. The purpose of the present investigation is to study chemical agents to remove radiocobalt from the victims and to provide a more reliable procedure for the treatment. The removals of radiocobalt from the NIH-(GP)mice injected intraperitoneally with lμCi of 58Co as CoCl2 were investigated with doses of either CaNa3 DTPA 8.4mg/0.2ml saline, CoNa3 DTPA 8.4mg/0.2ml saline, or saline 5ml. The radioactivity was determined by MCA and Ge-detector on 4, 8, 12, 48 hours and 7 days for the whole body, organ distribution and urine excretion. Six mice per each group were sacrificed for the measurement of cobalt retention in the parenchymal tissue. The cobalt trisodium chelate had a pronounced effect on reducing the whole body retention and increasing the excretion rate. Regarding to the systemic protective effects, CoNa3 DTPA, CaNa3 DTPA and saline were effected significantly in order. In conclusion, the extrapolations from these results to human were suggested that the rapid administration of cobalt trisodium chelate and an amount of saline to the contaminated person after internal contamination of radiocobalt were markedly increasing the decontamination effects.

The wastewater from textile industry typically containing high alkalify, salts, organic matter, and high color. Textile wastewater is usually treated by anaerobic-aerobic activated-sludge process. The activated-sludge process is effective the reduction of organic matter, but generally does not remove color. Ozone process is one of the most effective process in removal of color for the textile wastewater. Ozone has a strong oxidized dissolution of organism, deceleration, deodorization, fumigation, etc., regarding to water. This study focused on the color removal of textile wastewater. In this study, textile wastewater was treated strongly with ozone at 650mg/hr and the flow rate through ozone contact tank was adjusted to 5L/min. In an application Ozone treatment, Color was generally decreased with time, however, COD removal effect was not that good. In this study, the removal efficiencies of CODcr and Color were 23.5%, 80.4% respectively.
