Renal vein thrombosis (RVT) is not an uncommon condition amongst patients with nephrotic syndrome or malignancy. Septic pulmonary embolism (SPE) is associated with risk factors such as intravenous drug use, pelvic thrombophlebitis, and suppurative processes in the head and neck. However, acute pyelonephritis is a rare cause of RVT and SPE. Case reports on RVT and SPE due to acute pyelonephritis are rare. In most of the earlier cases, patients had underlying conditions such as diabetes mellitus, renal carcinoma, calyceal stones, and hyperhomocysteinemia. We report a case of acute pyelonephritis complicated by RVT and SPE that occurred in a patient without any predisposing risk factors for thromboembolism. RVT and SPE were diagnosed using computed tomography and ventilation/perfusion scan. The patient recovered with antibiotics and anticoagulation therapy without any surgical interventions.

警察秩序法上 危險槪念 및 表見危險과 危險의 疑心 : 독일경찰법학의 위험개념 검토를 중심으로

李起椿 한국공법학회 2003 公法硏究 Vol.31 No.4

Der begriff "Gefahr" ist immer noch unstritten. Die Auffassungen, die die Gefahr objektiv mit der ex-post-Sicht verstehen will, haben Zweck, Mißbrauchsmo¨glichkeit der Generalklauselsanwendung fu¨r Rechtsschutz der Adressaten mit begriff Gefahr zu kontrollieren. Aber fu¨r Polizeibeamten, unter Zeitdruck effektiv o¨ffentliche Interesse schu¨tzen zu mu¨ssen, ist Gefahr unter offer zu Ungewißheit zu verstehen. Soweit man diesen subjektiven Gefahr-begriff zustimme, sind die Begriffe "Anscheinsgefahr" und "Gefahrenverdacht" sowie "Gefahrerforschungseingriff" entbehrlich. Gefahr als eine der Tatbestandsvoraussetzungen der Generalklausel ist mit ex-ante-Betrachtungsweise zu beurteilen. Und sei zwischen gefa¨hrdetem Rechtsgut und Wahrscheinlichkeit des Schadenseintritts im Rahmen der Prognoseentscheidung eine Relation herzustellen (sog. je-desto-Formel). Je ho¨herrangiger das gefa¨hrdete Rechtsgut ist, je ho¨her der drohende Schaden ist, desto geringere Anforderungen sind an die Wahrscheinlichkeit des Schadenseintritts zu stellen. Daher sind fu¨r beurteilung der Gefahr der Rang des Rechtsguts, die Schwere des Schadens, die zeitliche Dringlichkeit wichtig. Schließlich nach dem normativ-subjektiven Gefahrbegriff ist Anscheinsgefahr die "echte" Gefahr. Und im Falle des Gefahrenverdachts ist Erkenntnis der Polizeibeamten u¨ber Ungewißheit des Schadenseintritts bedeutungslos fu¨r Rechtma¨ßigkeit der Eingriffe. Dabei mu¨ssen die Eingriffe nicht "vorla¨ufig" sind, soweit Verha¨ltnisma¨ßigkeitsgrundsatz befolgen wird.

산업적으로 산도 17.0% 이상의 고산도 식초를 생산하기 위하여 반연속식인 1st stage와 유가식인 2nd stage로 구성된 two stage 초산 발효를 온도 30 ℃, 교반속도 600 rpm, 통기량 0.1 vvm에서 실시하였다. 1st stage에서 초기 에탄올 농도를 50.0 g/ℓ, 잔류 에탄올 농도를 5.0 g/ℓ로 정하여 반연속적으로 초산발효를 하고, 2nd stage 에서 발효시간의 경과에 따라 에탄올을 유가식으로 첨가하여 초산발효액내의 에탄올 농도를 5.0 g/ℓ에서 10.0 g/ℓ로 유지했을 때 산도가 17.6%인 고산도 식초를 생산할 수 있었으며, 또한 이 ??의 최대 초산 생산성은 3.3 g/ℓ·hr였다. The production of vinegar containing 16.0 ∼18.0% of acetic acid was examined in two stage fermentation consisting of semi-continuous and fed-batch type. The optimum conditions were obtained when the fermentation was carried out at agitation of 600 rpm, aeration of 0.1 vvm and temperature of 30℃. The initial and residual ethanol concentration in 1st stage were 50.0 g/ℓ and 5.0 g/ℓ, respectively, and the ethanol concentration in 2nd stage was maintained from 5.0 to 10.0 g/ℓ. The maximum productivity was 3.3 g/ℓ-hr and the acidity was 17.6% after the two days of acetic acid fermentation.

이기형,전정열 慶熙大學校 1983 論文集 Vol.12 No.-

A 41-year-old-woman with hypertension and hypokalemia underwent adrenalectomy for primary aldosteronism, She was found to have and adenoma in right adrenocortical region on pathologic result. The diagnosis was made by finding low plasma renin activity, which could not be stimulated, and unsuppresable elevated plasma or urin aldosterone. The localization of an adenoma was accomplished by adrenal angioraphy, venography ultrasonogram, and CT. The CT was more helpful to identify the localization of the tumor than other radiologic studies. The patient was recovered completly from hypertension and hypokalemia after operation.

영양제로서 결정 NH₄H₂PO₄를 첨가한 피혁 공장 폐수의 생물학적 처리

전명순,임병란,최기덕,이수구 서울산업대학교 산업대학원 1993 大學院論文集 Vol.2 No.-

피혁 공장 폐수의 생물학적 처리에 있어서 유입 폐수의 급격한 부하변동, 독성물질의 유입 및 미생물의 성장에 필요한 각종 영양소의 불균형 등으로 인해 처리효율이 낮고 운전관리상 어려움이 많다. 따라서 본 연구에서는 피혁공장 폐수의 생물학적처리효율을 높이기 위하여 각종 영양제의 주입에 따른 처리효과에 관한 실험을 실시하여 적절한 영양제를 선정하고, 최적 주입량 등을 결정 하였다. 실험대상 폐수는 반월공단내의 피혁 공단 폐수로서 중화 및 응집참전 밥법으로 전처리 한 후 포기조에 유입되는 폐수를 대상으로 하였다. 영양제로는 회분식 실험에서 피혁폐수의 처리효율이 가장 우수한 것으로 나타난 결정 APM (ammonium phosphate monobasic, NH₄H₂PO₄)을 이용하였다. 연속식 활성 슬러지 공장에 있어서 폐수의 유량, 슬러지 반송율, 결정 APM 주입량 등을 변화시켜 그에 따른 처리효율에 미치는 영향을 실험 고찰하였으며, 생물 반응공학적인 반응해석을 통하여 설계에 필요한 반응상수 등을 구하였다. 연속식 활성슬러지법에서체류시간 12시간의 조건에서 영양제 미주입시 BOD 제거효율은 68%에 불과하였으나, 영양제로서 요소와 인산을 주입한 경우 73%로 증가하였으며 결정APM을 주입한 경우 90% 이상의 높은 처리율을 얻을 수 있었다. 결정 APM의 최적 주입량은 회분식 실험의 경우 300㎎/L이었으나, 연속식 실험의 경우 50㎎/L로 낮게 나타났는데, 이는 반송되는 슬러지내의 높은 인농도와 미량원소에 기인한다. 결정 APM을 50㎎/L 주입한 후 수리학적 체류시간을 6∼30 시간의 범위로 변화시켜 실험한 결과, BOD 제거효율은 체류시간 6시간에서는 67%에 불과하였으나, 12시간의 경우 93%, 30시간의 경우 98%이었다. 따라서 BOD제거효율 90%이상을 얻기 위해서는 수리학적 체류시간은 11시간 이상, F/M비는 0,65 ㎏ BOD/㎏ MLVSS·d 이하로 운전하여야 하는 것으로 나타났다. This study was performed to enhance the treatment efficiency of leather wastewater adding APM(ammonium phosphate monobasic, NH₄H₂PO₄) crystal as nutrient which contained the sufficient mineral components. The effect of APM crystal on biological treatment were studied and its optimum dosage and kinetic coefficients were determined. In the continuous activated sludge system for field wastewater of Banwol leather complex, BOD removal efficiency could be obtained over 90% with adding APM crystal, while it was 68% without nutrients and 73% with urea and phosphoric acid in the condition of HRT 12hr and SRT 3 days. The optimum dosage of APM crystal was 50㎎/L which was low compared with 300㎎/L in batch test due to recycling sludge contained high content of phosphate and mineral nutrients. In the condition of adding APM crystal 50㎎/L and hydraulic retention time in the range 6∼30hr, BOD removal efficiencies were 67% for HRT 6hr, 93% for 12hr and 98% for 30hr. In order to obtain over 90% of BOD removal efficiency, HRT should be maintained over 11 hr and F/M ratio within 0.65 ㎏ BOD/㎏ MLVSS·d.

Objective : Between 1991 and 1993 data were collected to evaluate risk factors for endometriosis. Design : A case-control study was conducted on 54 cases with laparotomically confirmed pelvic endometriosis consecutively admitted to CNUH. The control group consisted of 60 women admitted to hospital for benigh gynecologic disease. Results : No relation emerged with marital status, age at marriage, marital life, level of education, socio-economic status, age at menarche, menstrual regularity, number of spontaneous abortion, duration after last delivery, height and weight. But compared to control group, longer menstrual period, larger menstrual amount, severe menstrual pain, less number of parity, and less number of induced abortion signifcantly increased risk of endometriosis Conclusions : This study showed that frequent menstrual cycles and long period of menstruation with frequent and large amount of retrograde menstrual flow increased the risk of endometriosis.

To study the effects of exposure to carbon disulfide on blood pressure and serum cholesterol level, we gathered the informations from file of the periodic health examination for occupational disease, the periodic health examination for general disease and medical records in, Wonjin factory clinic. The study subjects were 266 workers who had worked in spinning department as exposure group, and 207 male office workers and 59 female office workers as non-exposure group. The results are as follows; 1. The slope coefficients of systolic blood pressure(as dependent variable) and age and exposure duration(as independent variable) were 0.013 and 0.066 respectively in exposure group. And the slope coefficients of diastolic blood pressure(as dependent variable) and age and expoure duration(as independent variable) mere 0.010 and 0.051 respectively in expoure group. 2. The slope coefficients of systolic blood pressure(as dependent variable) and age and tenure duration(as independent variable) were 0.019 and 0.009 respectively in male unexposure group, and were 0.032 and 0.018 respectively in female unexposure group. And the slope coefficients of diastolic blood pressure(as dependent variable) and age and tenure duration(as independent variable) were 0.016 and 0.009 respectively in male unexposure group, and were 0.019 and 0.033 respectively in female unexposure group. 3. The slope coefficient of exposure duration was greater than that of age in exposure group and that of age was greater than that of tenure duration in male unexposure group. 4.There was no significant difference of blood pressure between the exposure and non-exposure group. 5.The slope coefficients of Serum cholesterol(as dependent variable) and age and exposure duration(as independent variable) were 0.03 and 0.035 respectively in exposure group. The slope coefficients of serum cholesterol(as dependent variable) and age and tenure duration(as independent variable) were 0.102 and -0.012 respectively in male unexposure group. And the slope coefficients was very low in female unexposure group. 6. The slope coefficient of exposure duration was similar to that of age in exposure group, and only age was positively related to serum cholesterol in male unexposure group.

강길전,이오성,이기환 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

A clinical study was performed to evaluate the significance of 77 patients with salpingitis isthmica nodosa(SIN)who were confirmed on surgical specimens. The results were as follows. 1. The prevalence age of SIN was 30 decade. 2. The suspicious causative factor was not found from past history. 3. Bilaterality was found only 1/3 of cases. 4. Nearly twenty percent of SIN patients was found as ectopic tubal pregnancy. Accordingly, if HSG is suggestive of SIN, microsurgical removal of SIN lesion will be preventive measure for ectopic pregnancy. 5. Nearly one quarter of SIN patients was found as infertility. Accordingly, if HSG is suggestive of SIN and all infertility work-up are normal, microsurgical correction of SIN will be valuable.

The study was conducted to investigate the effect of different light qualities and day lengths controlled by using Light-Emitting Diode (LED) of blue, red, or blue plus red provided by LED System on flowering and growth of F1 Cyclamen miniature. Cyclamen persicum 'Dixie White' seedlings which have raised for 170 days after sowing were grown under conditions of 20° C air temperature and 60% relative humidity. Day length was controlled by blue, re, or blue plus red light (1:1 in energy ratio) with 10 or 12 hr for 63 days. Photosynthetic photon flux in the treatments with 10 or 12 hr was about 100 or 83 μmol m-2 s-1, respectively. Fluorescent lamp treatment of 12 hr day length was considered as a control. Flowering and growth in all the treatments were significantly affected by light quality or day length tested in the experiment. Number of flowers, which opened above the leaf canopy, was higher in red light treatment with 10 hr day length than that in control. Days to flowering were the shortest in day length treatment of 10 hr per day with blue plus red light among the treatments. Blooming period was also the longest in red treatment regardless of day length and mixture light treatment, and thus above 20 days prolonged than that in control. Otherwise, number of unfolded leaves or net photosynthetic rate was not significantly affected by the different light qualities and day lengths.
