        Chronic prostatitis/chronic pelvic pain syndrome in adolescents compared with that in young adults

        이건철,조인래 대한비뇨의학회 2017 Investigative and Clinical Urology Vol.58 No.4

        Purpose: Chronic prostatitis (CP)/chronic pelvic pain syndrome (CPPS) has been studied mainly in adults; reports in adolescents are rare. We compared the clinical characteristics of adolescent CP/CPPS patients with those of young adults. Materials and Methods: We retrospectively analyzed 20 adolescents with CP/CPPS aged <20 years who visited our outpatient department from August 2005 to April 2012. The control group comprised 120 young adult CP/CPPS patients. A complete medical history, physical examination, the national institute of health-chronic prostatitis symptoms index (NIH-CPSI) questionnaire, urinalysis, expressed prostatic secretion (EPS) or semen analysis, transrectal prostate ultrasonography, and prostate-specific antigen (PSA) were performed. Based on the EPS or semen analysis, patients were divided into category III-A or III-B. Results: The mean age was 16.5±2.0 and 32.8±5.0 years in the adolescent and control groups, respectively. A sexual activity history was seen in 2 patients; 9 and 11 patients were in category III-A and III-B, respectively. The PSA was 0.65±0.39 and 1.22±0.48 ng/mL in the adolescent and control groups, respectively. The prostate size was 12.4±4.4 and 21.0±4.9 g in the adolescent and control groups, respectively. The NIH-CPSI scores in the adolescent group were 9.2±5.2, 5.5±3.5, 7.5±3.2, and 22.2±8.1 for pain, voiding, quality of life (QoL) domains, and total scores, respectively. The adolescent group showed a tendency to exhibit high voiding symptom scores. Conclusions: CPPS has an equally severe impact on QoL in adults and adolescents. Apart from high voiding symptom scores in adolescents, no difference was found in terms of urologic clinical parameters.

        잔골재 대체재로서 바텀애쉬를 이용한 초속경 그라우트재의 수밀성 및 내구특성

        이건철,오동욱,조병영,김영근,조정기,Lee, Gun-Cheol,Oh, Dong-Uk,Cho, Byoung-Young,Kim, Young-Geun,Cho, Chung-Ki 한국건설순환자원학회 2011 한국건설순환자원학회지 Vol.6 No.3

        본 연구에서는 산업부산물로서 재활용율이 낮은 바텀애쉬와 혼화재를 이용하는 에코개념의 터널 보수용 초속경 그라우트 모르타르 개발을 목적으로 실시공 환경조건의 온도하에서 초속경 그라우트 모르타르의 수밀성 및 내구특성에 대하여 검토하였다. 수밀성으로 투수량 및 물흡수계수는 석탄회를 이용하는 시리즈 II의 경우가 증가하는 것으로 나타났으며, 온도조건별로는 $20^{\circ}C$ 양생조건이 $5^{\circ}C$ 양생조건 보다 투수량이 적은 것으로 나타났다. 또한, 본 연구범위 모든 시료는 KS F 4042(콘크리트 구조물 보수용 폴리머 시멘트 모르타르) 투수량 기준인 20g 이내를 만족하는 것으로 나타났다. 내구성으로 중성화 저항성은 고로슬래그 미분말로 치환 사용에 따른 단위시멘트량 감소로 약간 저하하는 것으로 나타났다. 또한, 내알칼리성 및 내산성 결과는 시리즈 I의 경우 수산화칼슘용액에 침지후의 압축강도가 침지전의 압축강도에 비해 저하하는 것으로 나타났다. 반면, 시리즈 II의 경우 강도저하가 미비한 것으로 나타났으며, $5^{\circ}C$ 양생조건의 경우 C 타입의 시멘트를 제외하고는 28일 재령의 압축강도와 동등한 값을 나타내어 고로슬래그 미분말 및 버텀애쉬를 치환 사용한 경우 내알칼리성 및 내산성이 큰 것 알 수 있었다. In this study, in order to develop ultra rapid hardening mortar(URHM) for tunnel repairs using bottom ash of low recycle ratio and Admixture as Eco concept, watertightness and durability properties of URHM on temperature condition of construction field were performed. Test result, seepage quantity and water absorption coefficient regarding watertightness of URHM were as in the following : series II > series I. Seepage quantity for the standard condition were smaller than low temperatures. all specimens were satisfied below 20g as standards of seepage quantity on KS F 4042. Because of the decrease of unit cement content by to replacement of blast furnace slag, the neutrlization resistance for durability properties was reduced. The result of alkali resistance and acide resistance, compressive strengths for specimens soaked in calcium hydroxide solution of seriesI were lower than compressive strengths for specimens not soaked. On the other hand, the case of series II show that the deterioration of compressive strengths for specimens was not almost showed. Compressive strengths of specimens soaked were similar with specimens not soaked except series II-C in $5^{\circ}C$. Therefore, specimens using both blast furnace slag and bottom ash were good in alkali resistance and acide resistance.

        플랭크 운동 시 불안정 지지면의 위치가 배근육의 두께 변화에 미치는 영향

        이건철,한지원,김수지,이승엽,이초롱,조아리,차예린 대한스포츠물리치료학회 2022 정형스포츠물리치료학회지 Vol.18 No.2

        Purpose: This study aimed to apply an unstable support surface to the upper and lower extremities and todetermine how the application of the upper and lower extremities affects the change in thickness of theabdominal muscles. Methods: The experiment was conducted by randomly classifying adults in their 20s into three groups: plankexercise groups that applied an unstable support surface to only the upper extremities, to only the lowerextremities, and to both the upper and lower extremities . The experiment was conducted three times a weekfor a total of 6 weeks. In this study, abdominal muscle thickness was measured using an ultrasound imagingdevice. Repeated measures analysis of variance was performed for statistical analysis. Results: Muscle thickness significantly increased in the oblique extrinsic, oblique oblique, and transversusabdominis according to the training period in all groups that performed plank exercise on unstable supportsurfaces (p<.05). Conclusion: Plank exercises on an unstable support surface for improving abdominal muscles in the clinicalfield can be applied according to the physical condition of the client.

        FRP 표면매립 공법 적용 무기계 내화 접착제의 기초적 연구

        이건철,박동철 대한건축학회지회연합회 2020 대한건축학회연합논문집 Vol.22 No.1

        In the case of aged structure, maintenance and reinforcement are inevitable for improving the performances and durability. Among the maintenance and reinforcement of the building structures, FRP surface mounted method has been suggested as a successful method in reinforcing efficiency, durability, and fire resistance with its increased adhesive area due to the mounting method of filling epoxy adhesive in groove at tensile area of reinforced concrete structure. However, the epoxy resin used as an adhesive can be lost its adhesive performance with fire conditions, the surface mounted method should be improved with inorganic adhesives against fire exposed conditions. In this research, with the aim of inventing a new inorganic adhesive for FRP surface mounted method, the fundamental properties and fire resisting performance of aluminosilicate based fireproof adhesive were assessed. As a result, under the high temperature conditions, aluminosilicate based adhesive showed higher adhesive performance than organic adhesives such as an epoxy resin.
