Clinical Studies on Postcoital Hematuria

이수형,김선일,안현수,김영수,김세중 대한비뇨의학회 2008 Investigative and Clinical Urology Vol.49 No.3

Purpose: A study was conducted to evaluate the clinical characteristics of patients with postcoital hematuria without bloody ejaculate. Materials and Methods: The records of 21 men(mean age 48.6 years, range 27-64 years) with isolated postcoital hematuria without bloody ejaculate were retrospectively reviewed. Patients underwent routine laboratory testing including coagulation studies and urological evaluation which included urinalysis, urine cytology, abdominal and transrectal ultrasonography, and cystourethroscopy. Results: Among total 21 patients, there were no detectable abnormalities in 11(52.4%) patients. Lesions were found in 10(47.6%) patients, which included 1 pathologically proven prostatic urethral hemangioma, 5 benign prostatic hyperplasia, 1 bladder neck obstruction, and 3 ultrasonographically identified seminal vesicle dilatation. In 19(90.5%) patients, symptom subsided after treatment or simple observation without recurrences. In the remaining two patients, postcoital hematuria has still persisted intermittently. Conclusions: Thorough evaluations are necessary in the case of postcoital hematuria as treatable lesions could be identified. In cases without identifiable causes, the patients could be reassured that the condition is benign and self-limiting.

짧은말뚝의 전도 파괴 시 작용하는 토압분포

이수형,이성진,이성혁,이진욱,이승현 한국방재학회 2013 한국방재학회논문집 Vol.13 No.5

모멘트에 의한 전도로 파괴되는 짧은말뚝에 작용하는 연직토압분포를 측정하기 위한 실물 재하실험을 수행하였다. 굴착 후 거푸집을 설치하여 콘크리트를 현장타설하고 되메우는 방식으로 설치된 단면 1.1 m×1.1 m, 근입깊이 2.2 m의 기초에 11개의 토압계를 설치하고 모멘트 하중을 가하여 기초를 전도시키는 실험을 수행하였다. 측정된 흙과 기초 사이에 발생하는 토압의 분포를 기존에 제시된 이론과 비교 분석하여 그 유효성을 평가하였으며, 지표 부분에 다짐이 이루어진 경우 이론에 의해 예측된것보다 더 큰 토압이 기초 상부에 작용하는 것을 발견하였다. 계측된 토압을 적용한 합리적인 설계가 가능할 수 있도록 기초에 작용하는 연직토압에 대한 단순화된 분포를 제안하였다. Earth pressures acting on a short rigid foundation during overturning failure were measured by a real-scale load test. A cast-inplace concrete foundation with square section of 1.0 m width and 2.2 m embedded depth was equipped with 11 earth pressure cells. Moment was applied to the pole supported by the foundation until overturning failure occurred. Earth pressure distribution between the foundation and soil was compared with those from the existing theories to verify their validities. In the measurement result, increase of earth pressure on the upper foundation was found in comparison with the theories, that was caused by the soil compaction at the ground surface. A Simplified distribution of vertical soil pressure on the foundation for the reasonable design was proposed.

Purpose : The aim of this study is to evaluate unwanted scattered dose to ovary by scattering and leakage generated from treatment fields of Tomotherapy for childbearing woman with breast cancer. Materials and Methods : The radiation treatments plans for left breast cancer were established using Tomotherapy planning system (Tomotherapy, Inc, USA). They were generated by using helical and direct Tomotherapy methods for comparison. The CT images for the planning were scanned with 2.5 mm slice thickness using anthropomorphic phantom (Alderson-Rando phantom, The Phantom Laboratory, USA). The measurement points for the ovary dose were determined at the points laterally 30 cm apart from mid-point of treatment field of the pelvis. The measurements were repeated five times and averaged using glass dosimeters (1.5 mm diameter and 12 mm of length) equipped with low-energy correction filter. The measures dose values were also converted to Organ Equivalent Dose (OED) by the linear exponential dose-response model. Results : Scattered doses of ovary which were measured based on two methods of Tomo helical and Tomo direct showed average of $64.94{\pm}0.84mGy$ and $37.64{\pm}1.20mGy$ in left ovary part and average of $64.38{\pm}1.85mGy$ and $32.96{\pm}1.11mGy$ in right ovary part. This showed when executing Tomotherapy, measured scattered dose of Tomo Helical method which has relatively greater monitor units (MUs) and longer irradiation time are approximately 1.8 times higher than Tomo direct method. Conclusion : Scattered dose of left and right ovary of childbearing women is lower than ICRP recommended does which is not seriously worried level against the infertility and secondary cancer occurrence. However, as breast cancer occurrence ages become younger in the future and radiation therapy using high-precision image guidance equipment like Tomotherapy is developed, clinical follow-up studies about the ovary dose of childbearing women patients would be more required.

지오셀을 이용한 투수성 포장의 지지력 평가

이수형,유인균,이대영 한국토목섬유학회 2012 한국지반신소재학회 논문집 Vol.11 No.3

본 논문에서는 하부층 연약지반 보강공법으로 사용되고 있는 지오셀을 이용한 투수성 도로포장의 지지력 거동 특성을 다루었다. 현장시험을 통해 지오셀 포장의 지지력 변화를 일반쇄석 포장과 비교하여 분석하기위해 FWD를 이용하여 지지력 특성을 평가하였다. 실험결과 1.5㎜ 두께의 지오셀의 경우 보강효과가 나타나는 것으로 측정되었으며 재하하중이 증가함에따라 보강효과도 큰 것으로 평가 되었다. This paper presents the results of investigation into bearing capacity of a geocell reinforced load base. In order to analyze variation of bearing capacity of the geocell reinforced road base comparing to without reinforced geocell road base, a series of full-scale tests were performed and measured using FWD (Falling Weight Deflectometer). The results indicate that bearing capacity of geocell (T=1.5 ㎜) reinforecd road base increase than the unreinforced road base.

Quetiapine 사용과 관련하여 발생한 당뇨병성 케톤산증 1예

이수형 대한내분비학회 2010 Endocrinology and metabolism Vol.25 No.3

New onset diabetes and diabetic ketoacidosis have been reported with administering atypical antipsychotics. Whereas clozapine and olanzapine are associated with a relatively high incidence of new onset diabetes and diabetic ketoacidosis, there are few case reports that have has been documented implicating quetiapine as the contributor to causing diabetes and diabetic ketoacidosis. I report here on a case of diabetic ketoacidosis that developed in a patient who was associated with quetiapine therapy. A 32-year-old woman with schizophrenia was transferred to the emergency room with diabetic ketoacidosis and vaginal bleeding. Seventeen months before this episode, she was hospitalized in an inpatient psychiatric institution and treated with quetiapine 1200mg, haloperidol 3mg, diazepam 5mg and benztropine 3mg with normal blood glucose levels. She had no personal and familial history of diabetes mellitus. She had no risk factors for diabetes mellitus and she also had no precipitating factor for diabetic ketoacidosis except for taking the atypical antipsychotic quetiapine. I believe that this case is the first case report of quetiapine associated diabetic ketoacidosis in Korea. Considering the unpredictability of hyperglycemia associated with quetiapine, monitoring the blood glucose should be part of the routine care when administering quetiapine.
