In aquaculture industrial field, an automatic management and control system is needed to cope with the difficulties such as expensive wage, ripe age of management worker and risk according to the unexpected change of environmental conditions in the aquarium. This paper introduces an automatic aquarium monitoring and control system. The system is developed using PC single board computer. A PC can be connected to multi-single board computers, and the communication between PC and single board computers is based on RS-422/485 interfacing method. The physical data of pH, DO, temperature and water level etc. are real-timely treated in the single board computer through individual transducers, transfered to the main monitoring PC through RS-422/485 communication, and those data are graphically shown on the PC monitor. Furthermore, the environmental circumstance can be monitored through the image processing system, and the emergency system can be operated under the condition of environmental incident such as electric power stoppage, DO deficiency, pump shut down and low level water etc.

목적: 본원에서 수술로서 치료한 요도 종물에 대해 임상적 고찰을 하고자 하였다. 방법: 1985년 1월부터 1994년 12월까지 만 10년간 본원에서 수술적 방법으로 치료한 82례에 대해 환자의 성별, 연령분포, 주 증상, 질환별 분류와 각각에 따른 치료 방법등으로 구분하여 조사하였다. 결과: 1) 이들의 연령별 분포는 10세부터 82세까지로 평균 48.7세였으며, 여자가 70례로 대부분을 차지하였다. 2) 주 증상은 요도 주위 이물감이 42례(51.2%)로 제일 흔한 증상이었으며, 점상 출혈이 20례(24.4%), 배뇨통이 12례(14.6%), 기타 잔뇨감, 빈뇨 등 다양한 양상을 보였다. 3) 요로감염으로 농뇨를 보인 경우가 14례(17.1%)이었으며, 혈뇨를 보인 경우는 10례(12.2%)이었고, 요배양 검사에서 E.coli가 8례(9.8%), Klebsiella가 1례에서 각각 검출되었다. 4) 질환별 빈도는 요도 육구가 40례(48.8%), 요도 게실 13례(15.9%), 요도 콘딜로마 10례(12.2%), 요도 평활근종 8례(9.8%), 요도 유두종, 요도 용종, 비정형중식증, 만성 염증이 각각 2례, 요도 평활 근육종, 요도 점막탈출, 요도 정맥 혈전증이 각각 1례 있었다. 요도육구는 조직병리학적으로 세형으로 분류할 수 있으며, 모세혈관 확장형이 24례(60%)로 다수를 차지하였고, 그외에 육이종형이 8례, 유두종형이 8례였다. 5) 이들의 치료는 전기 혹은 레이저 소작술을 이용한 외과적 절제술을 시행하였으며 요도 평활근육종에 대해서는 방사선 치료를 추가하였다. 결론: 이상의 결과로 요도에 발생하는 종물은 대부분 여성에서 발견되며, 그 중에서 대부분은 양성이고, 요도 육구가 절반 가까이를 차지하고 있으며, 전기 혹은 레이저 소작술을 이용한 외과적 절제술로 증상의 호전이 있었고 재발하는 방광염등이 없는 점등식으로 비교적 치료가 잘되는 것을 알 수 있었다. Objectives : Urethral masses are not common in urogenital disease. The purpose of this study is to investigate and analyze urethral masses. Methods : We reviewed 82 cases of urethral mass which were confirmed pathologically at Urology Department of Ewha Womans University Hospital from January 1985 to December 1994. Results : 1) Age distribution was between 10 and 82 years(mean age 48.7 years), showing the highest incidence in 31 to 60 years(53/82, 64.6%) and female to male ratio was 5.8:1. 2) Major symptoms were foreign body sensation of urethra(42/82, 51.2%), vaginal spotting (20/82,24.4%), dysuria(12/82, 14.6%), residual urine sensation and urinary frequency. 3) Among them, 40 cases were urethral caruncle(40/82,48.8%), 13 were urethral diver-ticulum(13/82, 15.9%), 10 were urethral condyloma(10/82, 12.2%), and 8 were urethral leiomyoma(8/82, 9.8%). 4) Among urethral caruncles, 24 cases were telangiectatic type(24/40, 60%), 8 were papillomatous type(8/40, 20%) and 8 were granulomatous type(8/40, 20%). 5) Surgical excision with electrocauterization or laser fulguration was performed in all cases and radiation therapy was added in case of leiomyosarcoma. Conclusion : These results suggest that urethral masses are more common in female than male, most of them are benign condition, urethral caruncle is a major disease, and surgical excision with electrocauterization or laser fulguration is a good treatment.

Wilms' tumor is the most frquent malignant abdominal tumor in children but is rare in adults. Adult Wiulms' tumor is less than 1% of all wilms' tumor, and has poor prognosis than childhood Wilms' tumor. Wilms' tumor in children classically demonstrate the curative potential of combined modality cancer therapy. However, guide line for management in adult Wilms' tumor is less clear. We reported a case of adult Wilms' tumor developed in 18 year-old male patient which was presented with right flank pain after slip-down for 1day.
