Purpose: When performing partial nephrectomy, there is a risk of excessive blood loss; this necessitates transfusion and it also results in deterioration of the renal function when a vascular clamp is used. We evaluated the usefulness of the microwave tissue coagulator for performing partial nephrectomy for renal cell carcinoma and benign renal tumors. Materials and Methods: From October 2000 to January 2005, partial nephrectomy was performed without renal pedicle clamping with using the microwave tissue coagulator for 9 patients with seven renal cell carcinomas and two angiomyolipomas. Results: In 6 patients, partial nephrectomy was successful with using the microwave tissue coagulator without renal pedicle clamping. The mean operative time and blood loss were 184 minutes and 223ml, respectively. For the remaining cases, three had positive tumor margins, so radical nephrectomy was performed for those cases. The mean creatinine level was not increased postoperatively. The mean preoperative and postoperative hemoglobin levels were 12.6g/dl and 11.7g/dl, respectively. Conclusions: Partial nephrectomy with using the microwave tissue coagulator can be safe and successful without performing renal pedicle clamping. However, the insertion line of the microwave electrode must be carefully determined for the resection to be curative, the same as when making the cut line for conventional partial nephrectomy

Fractal mathematics is being highlighted as a research method for classification of image. But the application of Fractal dimension(FD) has been requited the complicated calculation method because of its complex repetition progressing. In this paper, it has been developed the new approach method to express the Fractal Dimension(FD) for aging level calculation and estimation system of outside insulator using special image processing algorithm. As a result after FD testing, the recognized aging estimation of FD has a very characteristics compared to the conventional visual inspection.

Purpose: We compared the recovery periods in zoster-associated voiding dysfunction according to the treatment modality to establish the best treatment policy. Materials and Methods: From January 2004 to August 2006, medical records of 250 patients admitted for zoster infection were reviewed. Of 250 patients, patients complaining of lower urinary tract symptoms (LUTS) were selected. The clinical and urodynamic features, and treatment outcomes were analyzed. Results: Thirty eight (15.2%) of 250 patients had zoster-associated LUTS. Urinary retention was the most common symptom. Urodynamically, detrusor underactivity was the most common finding (71.8%). Twenty were followed, of which 5 received oral medication, 10 received clean intermittent catheterization (CIC), 4 received indwelling catheterization (IC) and remained 1 was observed without treatment. All patients regained normal voiding function. Mean recovery period was 12 days. According to the treatment modality, mean recovery period was 21 days in medication group, 10 days in CIC group, and 6 days in IC group. The mean recovery period was significantly shorter in CIC or Ie group than medication group (p=0.013, 0.005). Conclusion: Zoster-associated voiding dysfunction is a reversible condition. Thus, patients with mild symptoms can be observed. However, if symptoms are severe or retention develops, catheterization is recommended rather than medication alone.

Interval from Prostate Biopsy to Radical Prostatectomy Does Not Affect Immediate Operative Outcomes for Open or Minimally Invasive Approach

박범수,추설호,전황균,정병창,서성일,전성수,이현무,최한용 대한의학회 2014 Journal of Korean medical science Vol.12 No.12

Traditionally, urologists recommend an interval of at least 4 weeks after prostate biopsybefore radical prostatectomy. The aim of our study was to evaluate whether the intervalfrom prostate biopsy to radical prostatectomy affects immediate operative outcomes, witha focus on differences in surgical approach. The study population of 1,848 radicalprostatectomy patients was divided into two groups according to the surgical approach:open or minimally invasive. Open group included perineal and retropubic approach, andminimally invasive group included laparoscopic and robotic approach. The cut-off of thebiopsy-to-surgery interval was 4 weeks. Positive surgical margin status, operative time andestimated blood loss were evaluated as endpoint parameters. In the open group, therewere significant differences in operative time and estimated blood loss between the< 4-week and ≥ 4-week interval subgroups, but there was no difference in positivemargin rate. In the minimally invasive group, there were no differences in the threeoutcome parameters between the two subgroups. Multivariate analysis revealed that thebiopsy-to-surgery interval was not a significant factor affecting immediate operativeoutcomes in both open and minimally invasive groups, with the exception of the interval< 4 weeks as a significant factor decreasing operative time in the minimally invasive group. In conclusion, performing open or minimally invasive radical prostatectomy within 4 weeksof prostate biopsy is feasible for both approaches, and is even beneficial for minimallyinvasive radical prostatectomy to reduce operative time.

혼례의 근본 정신과 혼례의식의 개선

박범수 서울敎育大學校 學生生活硏究所 1999 學生生活硏究 Vol.25 No.-

예절은 시대에 맞게 개선되어야 한다는 정신에서 본 논문은 옛 것을 살피면서 새 것을 마련해 보려는 시도이다. 혼례를 선택한 이유는 통과 의례 중 혼례가 가장 큰 사회 문제를 야기 시키고 있으며, 계층간의 갈등을 일으킨다고 생각했기 때문이다. 옛 혼례는 음양이론을 기본 철학으로 하여 모든 절차가 엄격하였고 특히 예절 상대자에 대한 배려가 지극하였다. 혼례를 개인과 개인의 결합으로 보지 않고 종족간의 결합으로 간주하여 반드시 종족 대표자가 의사 결정에 관여하였다. 혼례는 三誓精神위에서 진행되었는데 三誓란 조상에 대한 서약, 부모에 대한 서약, 배우자에 대한 서약을 말한다. 옛 혼례는 자연의 섭리를 실현하기 위하여 우주의 원리를 바탕으로 시행되는 것이어서 엄격하고 확고하였으며 타인에 대한 심심한 배려 아래에서 진행되었으나. 현대의 안목으로 보면 결점도 있다. 남녀의 차별이 심하여 모든 의식이 남자 중심으로 진행되며, 인간관계를 상하위주로 보기 때문에 폐쇄적이고 보수적이었다. 혼례의 의사 결정에 당사자는 배제된 채 어른들이 결정하는 것이나, 신부가 시부모님께 인사하고 시댁의 조상을 알현하기 전에는 신랑이 신부의 부모에게 인사를 하지 아니하며, 더구나 신부의 아버지는 사위를 사양하는 손님으로 대해야 한다는 대목은 옛 혼례의 폐쇄성을 잘 대변하고 있다. 현행의 혼례를 살펴보면 문제점은 더욱 많다. 혼인의 의사 결정이 당사자 중심이어서 경박한 경우가 많고, 과다한 예물과 혼수는 반드시 시정해야 할 문제이며, 혼례식의 각종 진행과정이 관련되는 상인들의 상업주의에 의해 오도되는 경우도 많다. 의식의 진행에서 개인의 욕심이나 체면치fp는 반드시 배격되어야한다. 그런 점에서 우리의 옛 혼례는 본받을 점이 많다. 혼례의식의 개선을 위해서는 다음의 세 가지가 고려되어야한다. 첫째, 당사자의 유익함을 생각하되 먼 장래까지를 내다보고 지나치게 현재에 집착하지 말아야 한다. 둘째, 결혼 상대자의 입장으로부터 부모님, 그리고 주변에 있는 모든 타인들의 입장을 깊이 배려해야 한다. 셋째로 혼례의식이 사회에 미치는 영향을 철저히 가려야 한다. Under the thought that traditional culture should be changed as time goes by, this thesis will review traditional and modern wedding to see their good parts and bad parts. Then, we can try to plan how to change our wedding tradition to be perfectly fit for this modern society without causing any problems. Since wedding tradition causes the biggest social problem such as serious social distinctions. our wedding culture is selected as the topic of this thesis. Brief and clear outline about old and new wedding ceremony will be explained. Following, we will see three consideration's that can solve the problem of wedding tradition. "The Sun and the Moon Principle" is the basic philosophy of the traditional wedding. and the traditional wedding has been performed though complicated procedures which is based on "The Sun the Moon principle". Too careful obligation about their partners in traditional wedding is troublesome which does not have the beauty of just enough consideration to their spouses. Traditional wedding is concerned as the union of two people who love each other: the head of the family decided each marriage that sounds odd and extremely strange in modern society. Old wedding tradition proceeded upon " Three Conventions" that are the promises to their ancestors. parents. and spouses. On the other hands. this "Three Conventions" are lightly performed in modern wedding. To realize provision of nature, Traditional wedding was enforced under the metaphysical principle of the universe: Therefore, traditional wedding was strict and firmed, and it had performed under the deep and too profound consideration about all the people that could be the disadvantage in modern insight. Serious sexual discrimination and too much acceptance of their parents' decisions were the reasons of the problems of the traditional wedding. Every single wedding ceremony showed sexual discrimination: brides had to always greet their bridegrooms' parents, but bridegrooms should not greet parents of brides before brides were presented to their husbands' ancestors. Even, the father of the bride could not treat his son-in-law as his inferior so that son-in-law was always discomfort visitor. Moreover, bride and bridegroom's decision was ignored when their marriage was decided by their parents. actually people got married to the people who their parents decided by matching social classes without considering their son/daughter's emotional feelings. Current wedding ceremony has more problems than the traditional one. Only two people decide their marriage on their own decision without caring other family members' opinions. In addition, superabundant wedding presents, the wrong wedding method which was leaded merchants, excessive embellishment of personal dignity to show their richness or power should be gotten rid of. To make better wedding tradition, three main progressive conceptions should be considered. First, think about the happiness of the bride and the bridegroom by considering their better future than just their sweet dreams for this moment. Second, make thoughtful considerations in preparing marriage ceremony and inviting people for wedding. Demanding parents' sacrifice to pay for too expensive marriage expenses or unreasonable requesting to attend wedding ceremony to their friends and family who live far from then are examples of wrong consideration about marriage. Third, try to give a good influence in their society when planning wedding ceremony. Too luxurious marriage could be a good example which make bigger social disorder.

박범수,강창우,권현조,최승원,김선환,고현송,염진영,송시헌 대한뇌혈관외과학회 2013 Journal of Cerebrovascular and Endovascular Neuros Vol.15 No.3

Objective:This study was conducted to assess the efficacy and safety of endovascular mechanical thrombectomy (EMT) for patients diagnosed with basilar artery (BA) occlusion. Materials and Methods : We retrospectively analyzed clinical and imaging data of 16 patients diagnosed with BA occlusion who were treated with endovascular intervention from July 2012 to February 2013. Direct suction using the Penumbra system and thrombus retrieval by the Solitaire stent were the main endovascular techniques used to restore BA flow. The outcomes were evaluated based on rate of angiographic recanalization, rate of improvement of National Institutes of Health Stroke Scale (NIHSS) score, rate of modified Rankin Scale (mRS) at discharge and after 3 months, and rate of cerebral hemorrhagic complications. Successful recanalization was defined as achieving Thrombolysis In Cerebral Infarction (TICI) of II or III. Results : Sixteen patients received thrombectomy. The mean age was 67.8 ± 11 years and the mean NIHSS score was 12.3 ± 8.2. Eight patients treated within 6 hours of symptom onset were grouped as A and the other 8 patients treated beyond 6 hours (range, 6-120) were grouped as B. Successful recanalization was met in six patients (75%) for group A and 7 (87.5%) for group B. Favorable outcome occurred in 4 patients (50%) for group A and 5 (62.5%) for group B. Conclusion : Our study supports the effectiveness and safety of endovascular mechanical thrombectomy in treating BA occlusion even 6 hours after symptom onset.

박범수,정병창,전성수,이현무,최한용,서성일 연세대학교의과대학 2013 Yonsei medical journal Vol.54 No.4

Purpose: The use of laparoscopic radical cystectomy (LRC) for muscle-invasive bladder cancer is not yet widespread because of the technical difficulties of the procedure and the lengthy operating time. In this study, we report a single surgeon’s experience with LRC. Materials and Methods: Thirty patients (25 men and 5 women) with bladder cancer underwent LRC and ileal conduit by a single surgeon between November 2007 and May 2011. An extracorporeal urinary diversion was performed through 5-6 cm midline incision for specimen extraction. Results:The median operating time and estimated blood loss were 527.5 minutes and 275 mL, respectively. There was no conversion to open surgery. The median time to oral intake and postoperative hospital stay were 5 days and 12 days, respectively. The rates of immediate, early postoperative and late postoperative complication were 3.3%, 20% and 20%, respectively. With 16 months of median follow-up, the overall and recurrence-free survival rates were 70% and 56.7%, respectively. Conclusion: LRC is feasible for the management of invasive bladder cancer and, with appropriate patient selection, can be a good alternative to open or robot-assisted radical cystectomy in the era of robot-assisted surgery.

박범수,김영민,허무원,이상현 대한건축학회 2020 大韓建築學會論文集 : 構造系 Vol.36 No.1

In this study, various application schemes of seismic isolation system which can be applied to Hanok have been studied by analyzing itsstructural characteristics under seismic load. Structural stability of Hanok is more required against seismic load as Hanok becomeslong-spanned and multi-storied. To meet this goal, it becomes necessary to study more advanced technology such as seismic isolation designas well as seismic control design and seismic resistant design suitable to Hanok. Seismic isolation systems have been successfully applied toRC and steel structures to improve structural performance during earthquakes. Based on these previous study, we proposed four applicationschemes of seismic isolation design suitable for Hanok and analyzed their structural characteristics and applicability to Hanok in conceptuallevel based on its structural characteristics. The proposed four schemes are base isolation method, ground isolation method, roof isolationmethod and intermediate-story isolation method. The applicability of the proposed method was evaluated by performing boundary nonlineardynamic analysis to the typical Hanok for the two types of isolation method, that is, ground isolation method and roof isolation method, andthe results showed that the proposed methods produced good performance enough to be applied to Hanok. 본 연구에서는 한옥에 적용 가능한 면진기법을 제안하고 각 방안의 구조적 특성을 고찰하였다. 한옥이 장경간화 및 다층화 될수록 구조적 안정성에 대한 요구는 더 커지고, 이를 위해 내진 및 제진설계 뿐만 아니라 면진설계와 같은 보다 앞선 기술이 요구되고 있다. 한옥에 적용 가능한 네 가지 면진기법인 기초면진, 지상층면진, 지붕층면진, 중간층면진 방안을 제안하고, 각 방안들의 구조적 특성 및 적용성을 분석하였다. 사례 한옥에 지상층면진과 지붕층면진을 적용하여 경계비선형동적해석을 수행하여 한옥에의 적용성을 확인하였다.
