차량용 Printed On-Glass 안테나에 관한 연구
박상명,이중근 漢陽大學校 工學技術硏究所 1998 工學技術論文集 Vol.7 No.1
본 논문에서는 차량 뒷 유리와 열선과 유사하게 차 유리 표면에 패턴으로 실장 되어 사용 될 수 있는 Printed On-Glass 안테나의 특성을 해석 하였다. 먼저 도체 판을 동일한 크기의 세그먼트로 분할하고, 각각에 전류와 전하의 기저 함수를 가정 한 후 모멘트 법(Moment Method)을 사용하여 도체 판에 대한 산란 문제를 해석하였다. 또한 동일한 알고리즘을 Printed On-Glass 안테나 해석에 적용하였으며, 연산의 수를 줄이기 위해 안테나 요소(Element)를 세그먼트로 분할할 때 안테나 구조를 고려하여 각 세그먼트의 크기를 달리하여 해석하였다. 시뮬레이션 된 안테나 패턴상의 전류 분포로부터 안테나 임피던스와 복사 패턴을 계산하였으며, 시뮬레이션과 실제 측정치를 비교한 결과 서로 유사함을 알 수 있었다. The objective of this paper is in the analysis and simulation of the characteristics of an automobile printed On-Glass antenna. With numerical methods (Moment Method), scattering problems on a finite flat conducting plate are analyzed by segmentation of the conducting plates, and assumed a current and charge basis function for each segment. Then these algorithms are applied to a printed On-Glass antenna problem. Segment sizes were adaptively chosen to save the calculation times. From the simulated current distribution on antenna patterns, antenna impedances are calculated, and radiation patterns are simulated. Then these are compared with the measured values, which turned out to be similar to each other.

감성공학에 의한 운전자의 가로경관 평가요인 분석에 관한 연구
박상명,남궁문,이병주 대한교통학회 2006 대한교통학회지 Vol.24 No.3
Recently, flowerbed median strips are being installed in urban highways for safety and scenery. In addition, efforts to enhance urban image through roadside flowerbeds and trees are being exerted for afforestation to enhance the urban environment. The sensibility of humans, such as the feeling of agreeableness of drivers must be considered when planning roads. However, not many researches on users on road environment are being conducted.Accordingly, KANSEI Engineering that is attracting attention nowadays was applied to form the image or sensibility of humans as definite object, in order to grasp the relation between the personal attributes of users and road formation with sensible factors considered when the road users evaluates the road scenery.As the result of research, streetscape was not evaluated based on individual factors such as roads, trees and buildings that form roads, but was based on sensibility image based on harmony of the overall road formation according to the changes of each factors. 최근 도심지에는 간선도로의 안전성과 경관성을 고려하여 화단형 중앙분리대를 설치하고 있다. 또한, 도심지 환경개선을 위한 도로변 녹지조성과 가로수 식재 등을 통한 도시의 이미지 개선을 위한 노력이 계속되고 있다. 따라서 도로 설계단계에서 운전자가 느낄 수 있는 쾌적성 등과 같은 감성적인 측면을 고려할 필요가 있다고 생각되지만 도로환경에 대한 이용자 측면의 연구가 미흡한 실정이다.이에 본 연구에서는 인간이 가진 감성이나 이미지를 구체적인 물체로 만들 수 있는 공학적인 방법으로 최근 주목을 끌고 있는 감성공학을 적용하여 도로이용자가 도심지의 기초경관을 평가하는데 있어 고려하는 감성요인과 개인속성 및 도로 구성요소간의 관계를 파악하고자 하였다.연구결과, 도심의 가로경관은 도로를 구성하는 도로, 가로수와 주변 건물 등 개개의 요소에 의해 평가되는 것이 아니라 각 요소들의 구성비에 의한 전체 도로 구성요소의 조화에 의한 감성이미지에 의해 평가된다는 것을 알 수 있었다.

직장 내 리도카인젤리 투여 및 전립선주위신경차단술 병행의 전립선 재생검 시 통증 경감에 대한 효과
박상명,홍성주,노상휴 대한비뇨의학회 2005 Investigative and Clinical Urology Vol.46 No.10
Purpose: We evaluated the effectiveness of intrarectal lidocaine-gel and periprostatic nerve block, or the combined method, on the reduction of pain during repeated transrectal prostate biopsy. Materials and Methods: 61 patients with a negative pathology after an initial sextant biopsy, with no sedatives or analgesia, were rebiopsied using the 12 extended biopsy technique. The patients scheduled for a repeat prostate biopsy were randomized to the combination method(group 1, 19 patients), periprostatic nerve block(group 2, 23 patients) or intrarectal lidocaine-gel(group 3, 19 patients). After the repeat biopsy, the rectal pain during probe insertion, pain intensity during prostate biopsy and complication rates were recorded. Pain was evaluated by a 10-point linear visual analogue scale(VAS). An ANOVA test was used as the statistical analysis for the assessment of VAS, with p<0.05 considered significant. Results: No significant difference was found in mean patient age, prostate specific antigen level, prostate volume and complication rates between the groups. The VAS during probe insertion were significantly lower in group 1 and 3(mean 1.74 and 1.84) than in group 2(mean 3.96, p<0.001). The VAS during biopsy was significantly lower in group 1(mean 3.05) than group 3(mean 4.63, p<0.001). Conclusions: Periprostatic nerve block decreased pain during the repeated prostate biopsy, but had no effect on the pain felt during transrectal probe insertion. Intrarectal lidocaine-gel decreased the pain only during probe insertion. However, the combination of intrarectal lidocaine-gel and periprostatic nerve block was effective in reducing the pain, both at biopsy and during probe insertion, in the repeated 12 core biopsy.

We present an unusual case of a penile cavernosal abscess. This patient did not improve clinically despite repeat percutaneous aspiration of the abscess and administration of oral fluoroquinolone. Surgical drainage was required. Culture of pus and infected tissues were negative. Three months postoperatively, penile deviation to the left side and erectile dysfunction occurred but the patient was able to have sexual intercourse by using the medication of oral vardenafil. Colchicine was administered orally to the patient for 9 months and the penile curvature was improved.

Adenomatoid tumors arising in the tunica vaginalis are relative rare neoplasms, and usually benign in nature. An appropriate treatment of an adenomatoid tumor is local excision. Herein, a case of an adenomatoid tumor of the tunica vaginalis, in a 40-year-old man, is described. An orchiectomy was performed to excise the mass, and pathologic evaluation revealed an adenomatoid tumor of the tunica vaginalis. (Korean J Urol 2004;45:1171-1173)
