본 연구에서는, 안산정수장에 구축된 수도시설 운영정보화 시스템에 의한 처리수질개선 등 정수장 효율개선효과를 평가하였다. 분석기간 동안의 안산정수장 생활용수 유입유량은 운영정보화 시스템이 구축되기 전인 2004년도보다 구축 후인 2005년도가 약 15.6% 감소한 것으로 나타났다. 원수의 평균탁도는 2005년 12.37 NTU, 2004년 12.06 NTU로 비슷한 값을 나타내었으나, 연평균 응집제의 주입농도는 2005년도가 12.06 mg/L으로 2004년(10.31 mg/L)보다 다소 높은 것으로 나타났고, 정수탁도는 약간 개선된 처리효율을 나타내었다. 원수의 CODMn 및 BOD 등의 분석결과, 2004년보다 2005년의 원수수질이 개선된 것으로 판단할 수 있었다. 정수의 KMnO₄ 소비량은 2004년(2.95 mg/L)보다 2005년은 1.25 mg/L로써 그 양이 줄어들었고, THMs의 농도도 2004년(0.038 mg/L)보다 2005년 0.025 mg/L로써 다소 개선되었다. 본 연구결과, 약품주입 등 정수장 운영은 운영 정보화 시스템의 구축에 의해 보다 최적의 상태를 도모할 수 있으며, 이에 따라 수질개선효과도 있음을 판단할 수 있었다. In this study, the improvement of the operation condition and the water quality in water treatment plant by operating information system(OIS) was evaluated for Ansan water treatment plant. The average flow rate of raw water in the year 2005(after constructing the OIS) appeared 15.6 % lower than that in the year 2004(before constructing the OIS). The mean value(12.37 NTU) of raw water turbidity in the year 2005 remained constant, or nearly so with that(12.06 NTU) in the year 2004. The average dosing rates of coagulant appeared 12.06 mg/L in the year 2005 which was higher than 10.31 mg/L in the year 2004. Furthermore, the average turbidity concentration of fresh water in the year 2005 appeared slightly better than that in the year 2004. From CODMn and BOD concentration of raw water, the water quality in the year 2005 were better than those in the year 2004. The average concentration of KMnO₄ in the year 2004 and the year 2005 was 2.95 mg/L and 1.25 mg/L, respectively, and the average concentration of THMs in the year 2004 and the year 2005 appeared 0.038 mg/L and 0.025 mg/L, respectively. Therefore, the fresh water quality in the year 2005 was better than that in the year 2004. In this study, it is considered that the operation of Ansan water treatment plant may be optimized by OIS, and thus the OIS may be very useful method to improve the water quality.

Nocturnal enuresis is a symptom rather than a disease. Lots of theories have been proposed to explain why children with nocturnal enuresis fail to recognize or respond to their full or contracting bladder during sleep. Although these theories, which include behavioral, genetic, developmental, neurologic, psychological, urodynamic, and organic causes, are diverse and may be able to explain selected cases, there is no single explanation for this symptom, and in each individual multiple factors may be operative. Clearly, the vast majority of children with nocturnal enuresis do not suffer from psychiatric, neurologic, or urologic disturbances, and investigation and treatment along these lines is both inappropriate and unrewarding. A number of treatment modalities have been used for nocturnal enuresis, but their effectiveness, even in controlled studies, has been difficult to assess because of the high spontaneous annual remission rate (15%) and the extremely high placebo improvement effect, which can exceed 65%. Proven, reproducible, and effective therapy has evolved along two lines: drug therapy and behavioral modification. The physician who cares for patients with enuresis must develop an orderly, practical, and effective approach to evaluating and treating the children who present with nocturnal enuresis.

Primary urethral carcinoma in females is uncommon neoplasm that only 0.02% of all types of cancer in women. Understanding the feature and character of disease has helped us select proper treatment in individual case. We report a case of primary transitional cell carcinoma of the female urethra with brief review of the literature.

Superficial venous thrombosis of the chest wall was first described by Mondor in 1939. Braun-Falco reported in 1955 superficial penile vein involvement in diffuse thrombophlebitis of the abdominal wall and in 1958 Helm and Hodge first described isolated superficial dorsal penile vein thrombosis. Since then, fewer than 50 cases have been reported. The clinical presentation is usually redness and swelling of the dorsum of the penis, accompanied by a palpable, tender thrombotic vein. This acute and painful disease frightens the patients, who is concerned about his fertility and sexual function. The main cause of this disease is frequent sexual intercourse. Diagnosis is based upon anamnesis, physical examination and penile sonography with color Doppler imaging. It is usually a benign disease which resolves quickly under appropriate medical therapy. We present a man who was visited for this condition and was conservatively treated.

Renal artery thrombosis may result from external trauma of a blunt nature. Such injury is induced by rapid deceleration resulting in the stretching of the renal vasculature, disruption of the arterial intima-the least elastic layer of the arterial wall and eventual thrombosis. The treatment of renal artery thrombosis is controversial, with physician's options divided between prompt surgical exploration with vascular repair and clinical observation. We experienced 1 case of traumatic renal artery thrombosis and report that with a brief review of the literature.

Sparoganosis is a parasitic infestation of human by a lavel form of an animal tapeworm, genus spirometra. ingestion of raw or undercooked flesh of numerous intermediate hosts results in human infection. Sparganum is usually found in the subcutaneous tissues of various parts of the body, but other sites, such as orbit, brain, and the abdominal viscera, have been recorded. we experienced a case of sparganosis it the spermatic cord.
