Purpose: A laparoscopic procedure is considered the treatment of choice for an adrenalectomy. We report our experience of a laparoscopic transperitoneal adrenalectomy in a series of 41 patients. Materials and Methods: Between February 1999 and September 2004, 41 consecutive patients underwent a laparoscopic transperitoneal adrenalectomy. The indications for a adrenalectomy were primary aldosteronism in 16 patients, Cushing's syndrome in 7, pheochromocytoma in 6, nonfunctional adenoma in 5, adrenal cyst in 3, benign cystic teratoma in 2, myelolipoma in 1 and metastatic renal cell carcinoma in 1. The author analyzed the results of each operation. Results: The affected adrenal gland was successfully removed, with the exception of 3 cases. Conversion to open surgery was necessary in 3 of the pheochromocytoma patients due to massive intraoperative bleeding and severe adhesion to retroperitoneal fat. The mean operative time was 245.3 minutes(125-420). The mean intraoperative blood loss and adrenal mass size were 189.6ml(20-2100) and 3.6cm(1.0-10.4), respectively. The mean post-operative hospital stay was 10.4 days(5-29). The mean times to oral intake and ambulation were 1.4(1-3) and 1.0 days(1-2) after the operation, respectively. The mean number of days of analgesic administration was 2.1(0-6). The conversion and major complication rates were 7.3 and 10.5%, respectively. Conclusions: A laparoscopic adrenalectomy is safe and effective in nearly all adrenal pathologies, with early oral intake, ambulation and a low number of days of pain control.

Misplacement or Migration? Extremely Rare Case of Cardiac Migration of a Ureteral J Stent

김태남,이찬호,공도훈,신동길,이정주 대한비뇨의학회 2014 Investigative and Clinical Urology Vol.55 No.5

A 29-year-old woman with mild back pain when coughing and suprapubic discomfort after voiding was admitted to Pusan National University Hospital. Two weeks earlier, she had undergone a hysterectomy and right-sided ureteroneocystostomy for uterine atony and right ureteral injury with bladder rupture. Computed tomography showed that a ureteral J stent extended from the right ovarian vein to the right cardiac chamber. The stent was retrieved via both femoral veins with a snare loop and pigtail catheter. Computed tomography showed that the urinary and vascular tracts were normal 5 months after the procedure.

본 연구의 목적은 강원도 산악지역에서 교량 설계 지침 개발에 있다. 2002년 태풍 루사, 2003년 매미, 2006년 에위니아에 이은 7월 집중호우로 강원도 산악지역에서는 큰 피해를 당한 바 있다. 이런 피해의 원인은 강원도 산악지역에 위치하는 하천의 지역적, 지형학적 조건을 고려하지 못한 부분적인 이유도 있는 것으로 판단된다. 교량피해의 대부분은 교각과 교대의 기초부분 세굴(침식) 때문에 발생되었다. 다른 이유로는 고사목, 나뭇가지 및 부유잡물 등이 교각과 상판에 걸려서 물의 흐름을 어렵게 만들거나 차단 시켜서 발생되었다. 수해현장의 피해 형태와 원인 등을 분석하여 이로부터 설계 지침을 제시하였다. The purpose of this study is development of bridge design guidelines in Kangwondo mountain area. Much damages heve been wrought by Typhoon Rusa(2002), Maemi(2003), Ewinniar(2006) and severe rain storm in July 2006 in Kangwondo mountain area. The partial cause of these much damages are not consider the regional and geomorphologic condition of river in Kangwondo mountain area. Most of the bridge damages were caused by severe wash out the foundation of pier and abutment. As other reasons, dead trees, branches of the trees and floating materials were catched by pier and deck which make difficult or cut off the flow. Design guidelines are presented by analysis the types and reasons of damages of the disaster.

우리나라 대학생들의 창업에 대한 의식조사 연구 - 건설업을 중심으로 -

최근 3년간 (2011~2009) 신입생을 대상으로 실시한 조사에서 취업을 희망한다는 경우 60.2%(3년간 평균치), 자영업 포함하여 창업을 희망하는 경우가 4.0%, 유학 포함하여 대학원 진학이 13.5% 그리고 나머지는 구체적 계획이 없는(22.3%) 것으로 조사 되었다. 극히 적은 수가 창업을 원하고 있는 것으로 나타났다. 신입생들은 창업이 불확실하다고 생각하고 따라서 창업보다 취업의 안정성을 크게 선호하고 있는 것으로 조사되었다. 본 연구는 건설회사 창업과 관련된 문제점 및 원인을 조사, 분석하고 그 대안을 제시하는데 목적이 있다. 조사 및 분석 대상은 건설공학 전공자에 대하여 실시하였다. In the past three yesrs(2011-2009), a recent study found that the freshman demand employment 60.2%(average the three yesrs), foundation of company(include self-empolyment) 4.0%, entrance into graduate school(include study abroad) 13.5% and the others are net yet decision 22.3%. Very small numbers are want to establish company's business. Freshman prefer employment's safety than the foundation of company can be chancy business. The purpose of this study is survey and analyze out the reason, then present an alternative proposal in the problem concern of establish construction company's business. The survey and analyze out subjects for the students who majored in construction engineering.

흰쥐 방광출구 단기부분폐색에 의한 방광혈류 변화와 허혈에 관여하는 유전자 발현 변화

김태남,박영수,이정주 대한비뇨의학회 2005 Investigative and Clinical Urology Vol.46 No.9

Purpose: This study was aimed at evaluating the expressions of types I and III collagen, inducible nitric oxide synthase(iNOS), hypoxic inducible factor-1α(HIF-1α), vascular endothelial growth factor(VEGF) and the hemodynamic changes of the bladder during the acute stages of a partial bladder outlet obstruction(PBOO) in adult rats. Materials and Methods: Bladder specimens were aseptically removed from 35 Sprague-Dawley adult rats(8 week old, weight 250-300gm) of both sham and experimental groups at 6, 12 and 24 hours, and 2, 3, 5 and 7 days after establishing a partial bladder outlet obstruction. Bladder blood flow was measured at the left vesicular artery using a laser flowmeter. The expressions of types I and III collagen, iNOS, HIF-1α and VEGF in relation to changes of the bladder wall were evaluated by immunohistochemical staining and Western blot assay. Results: There was a significant difference in the vesical blood flow between the sham and experimental groups after the establishment of a PBOO. The bladder blood flow of the experimental groups was significantly decreased after establishing a PBOO of 3 days duration. The expressions of type III collagen and iNOS from the immunohistochemical staining of the bladder were markedly increased during the acute stages of a PBOO. The expressions of HIF-1α and VEGF from the Western blot of the bladder increased with duration of the obstruction. Conclusions: A decreased bladder blood flow during the acute stages of PBOO generally enhanced the expressions of iNOS and type III collagen. This study suggests that hypoxia of the bladder after establishing a PBOO induces the expression of HIF-1α, and then enhances the production of nitric oxide(NO) due to activation of iNOS, which finally results in bladder growth and a decrease in bladder wall compliance

Analytic solutions are the most common method for free vibration analysis of structures. In general some idealization of structure is always present in the mathematical model, so it is recommend to compare the results another methods. Experimental tests are useful in order to compare the analytic solutions and to improve the results. In this study, a free vibration analysis of cable-stayed bridge by small scale model tests have been carried out in order to understand their dynamic characteristics. The determined dynamic characteristics are more shapes, natural frequencies and damping ratios. The example of cable-stayed bridge is Dolsan bridge and the basic scale factor for the model is 1/150.

Short rare minisatellite variant of BORIS-MS2 is related to bladder cancer susceptibility

김태남,김원태,정미소,문미혜,김민혜,이정주,임선희 한국유전학회 2019 Genes & Genomics Vol.41 No.2

Background BORIS/CTCFL, a paralog of CTCF and member of the cancer-testicular antigen family, is abnormally activated in multiple cancers. Objective We investigated the relationship between polymorphic variants of the BORIS minisatellite 2 (BORIS-MS2), located within the 5′ upstream promoter region of BORIS, and bladder cancer. Methods We used case-control study with 516 controls and 113 bladder cancer patients. To evaluate whether minisatellite variants play a role in BORIS expression, we examined the transcript levels of a reporter gene linked to these minisatellites in cell lines. We also examined BORIS expression in cancerous and non-cancerous bladder tissue. Results A statistically significant association was identified between the short rare allele (13-repeat) and bladder cancer incidence (odds ratio (OR) 2.97, 95% confidence interval (CI) [1.14, 7.74]; P = 0.020). In particular, short rare alleles in the younger group (aged < 65) were associated with statistically significant increase in bladder cancer risk (OR 5.38, CI [1.32, 21.87]; P = 0.01). The BORIS-MS2 region acted as a negative regulator, and the expression level of the luciferase reporter in bladder cancer cells was less effectively inhibited than in normal cells. Furthermore, the expression of BORIS mRNA significantly differed (P < 0.05) between normal and cancerous muscle-invasive bladder cancer tissues, and relationship to clinical parameters was observed. Conclusions The short rare allele of BORIS-MS2 could be used to identify bladder cancer risk. BORIS expression levels have been shown to increase with the progression of bladder cancer, could be used as a biomarker for its progression.
