Autosomal dominant polycystic kidney disease(ADPKD) is one of most common hereditary disorder. It is potentially fatal and the major mobilities are hypertension and renal failure. To elucidate clinical characteristics and outcomes of ADPKD, 67 ADPKD patients were analyzed retrospectively. The male to female ratio was 48 years for males and 42 years for females. The factors leading to the dignosis of ADPKD were flank or abdominal pain (46%), palpable abdominal mass (24%), incidental findings (18%), gross hematuria and headache. Urinalysis result showed hematuria (31%), proteinuria (19%), pyuria (18%). Among renal complications hypertension (67%) was the most common. Other complications were urolithiasis (16%) upper urinary tract infection (9%), cyst infection (7%). Azotemia was observed in 24% of cases. Echocardiography showed left ventricular hypertrophy in 24% and valvular regurgitation in 18% of cases, but there was no mital valve prolapse. Cerebrovascular events occurred in 6 cases (2 cases of intervertebral hemorrhage and 4 cases of cerebral infarction). Hipatic cyst were observed in 64% of cases. Eighteen cases culminated in end stage renal failure (ESRF) at an of 47. According to this study, the most common complications of ADPKD was hypertension (67%), ESRF (27%), and cerebrovascular event (9%). Hypertension was more frequently observed in increased creatinine group than normal.

Phosphate remaining in wastewater treatment must be removed for the conservation of water quality in a water system. The concentration of phosphate can be decreased from a physic-chemical method for the discharge water of a sewage disposal plant. In this study, it was performed to examine the adsorptive characteristics of sand filter through batch and column experiments in saturated soil. Batch experiment evaluates the concentration change of phosphate with retention time and column experiment performs to analyze a breakthrough curve for phosphate adsorption. And the batch experiment result of adsorptive equilibrium was fitted for the Langmuir model and the Freundlich model. The results obtained from this study were summarized as follows; 1. In the batch experiment, the adsorptive capacity of PO_4^-3 by sand was below 47% of adsorption rate for retention 24 hours in the range of initial concentration 2.0㎎/ℓ ∼4.6㎎/ℓ. 2. The Langmuir and the Freundlich models on the adsorptive equilibrium were fitted well to both in a good correlation coefficient. 3. In the column experiment, the adsorptive breakthrough curve for input PO_4^-3(15.0㎎/ℓ) occurred to about 30ℓ. And output concentration was almost decided at initial breakthrough curve.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

Objectives : To clarify clinical features of panic disorder and to compare the characteristics of cognitive patterns, avoidance behaviors, and coping strategies among patients who have panic disorder with or without agoraphobia. Methods : Family backgrounds, cognitive patterns in the first panic attack, coping strategies, and avoidance behaviors were compared among the three groups classified by panic patients with mild agoraphobia(mild PDA=66), severe agoraphobia(severe PDA=71), and without agoraphobia(PD=21) Results : 1) Severe PDA reported significantly high panic attack frequency and more dysfunctional level than PD. 2) Catastrophic thinking of 'dying' in PD was significantly frequent than the other groups. Other fears of 'going craze or loss of control' in severe PDA were the highest among the three groups, though it was not significant. Specific thinking process or interpretation in the first panic attack was not significantly different among the three groups. 3) As avoidance behaviors became worse, the frequency of avoidance behaviors and the patters of avoidance behaviors increased. Conclusions : The results suggested that as avoidance behaviors became worse, the frequency of panic, maladaptive functioning and the patterns of avoidance behaviors increase. This might be why we need to decrease avoidance behaviors through exposure as the treatment.

It was researched that the possibility for developing multistage culture system to cultivate larvae by computer simulation with basic experiments. This culture system was composed of 3 stages. Chlorella sp. at the 1st stage are being supplied to the rotifer(Brachionus plicatilis) at 2nd stage, and the rotifer are bing feeded to larvae at the 3rd stage. In this study, Chlorella sp. were cultivated by batch culture to search for the possibility of continuous feeding rate Chlorella sp., ???????? and ??(cells/hㆍrotifer) in the multistage culture system, then the change of the rotifer concentration at 2nd stage was simulated by computer. The required amount of rotifer for the growth of larvae was also increased as the increase of the length of larvae. On the 9th day of the culture, the rotifer uptake rate of larvae was 250(cells/dayㆍlarvae). Based on these basic experiments and results. It was suggested that the possibility of multistage culture system to cultivate larvae with continuous feeding of Chlorella sp. and rotifer.
