The purpose of this study is to classify the factors influenced on the damages of head works suffered from the storm flood occurred on July 22 1980 in both Musim and Bochong rivers and to find out an integral counter measures against the causes influenced on the disaster of head works in the engineering aspect of planning, design, construction and maintenance. In this survey, number of samples was taken 25 head Works, and the counter measures against the causes of their disasters summarized was as follows, 1. In the aspect of planning a. As the flood water level after the establishment of head works is more increased than the level before setting of head works owing to having more gentle slope of river bed between the head works than nature slope of river bed. Number of head works should be reduced for the appropriate annexation of them b. In the place where head works is established on the curved point of levee, the destruction of levee becomes severe by the strong deflective current. Therefore the setting of head works on the curved point should be kept off as long as possible and in case of unavoidable circumstances the construction method such as reinforced concrete wall or stone wall filed with concrete and anchored bank revetments should be considered. 2. In the aspect of design a. As scoring phenomena at up stream is serious around the weir Where the concentration of strong current is present in such a place, up stream apron having impermeability should be designed to resist and prevent scoring. b. As the length of apron and protected bed is too short to prevent scoring as down stream bed, the design length should be taken somewhat more than the calculated value, but in the case the calculated length becomes too long to be profitable, a device of water cushion should be considered. c. The structure of protected river bed should be improved to make stone mesh bags fixed to apron and to have vinyl mattress laid on river bed together with the improvement for increasing the stability of stone mesh bags and preventing the sucked sand from the river bed. d. As the shortage of cut-off length, especialy in case of the cutoffs conneting both shore sides of river makes the cause of destruction of embankment and weir body, the culculation of cut-off length should be taken enough length based on seepage length. 3. In the aspect of design and constructions a. The overturing destruction of weir by piping action was based on the jet water through cracks at the construction and expansion joints. therefore the expansion joint should be designed and constructed with the insertion of water proof plate and asphalt filling, and the construction joint, with concaved shape structure and steel reinforcement. b. As the wrong design and construction of the weep holes on apron will cause water piping and weir destruction, the design and construction of filter based on the rule of filter should be kept for weep holes. c. The wrong design and construction of bank revetment caused the severe destruction of levee and weir body resulting from scoring and impulse by strong current and formation of water route behind the revetment. Therefore bank revetment should be designod and constructed with stone wall filled with concrete and anchored, or reinforced concrete wall to prevent the formation of water flow route behind the wall and to resist against the scoring and impulse of strong stream. 4. In the aspect of maintenance When the damaged parts occurred at head works the authorities and farmers concerned should find and mend them as soon as possible with mutual cooperation, and on the other hand public citizen should be guided for good use of public property.

목적: 발열이 있는 소아 신우 신염에서 단일 세균과 혼합 세균 감염군 두 군간의 임상적인 비교를 하였을 때, 통계학적으로 유의한 차이를 보이는지 알아보고자 하였다. 방법: 2008년 1월부터 2010년 8월까지 ${\bigcirc}{\bigcirc}$대학교 ${\bigcirc}{\bigcirc}$병원과 ${\bigcirc}{\bigcirc}$병원을 대상으로 2년 8개월간 발열이 있는 신우 신염 환아 95명 중, 치골 상부 방광 천자 및 도뇨관 채뇨에 의해 채취한 요 배양 검사 상 단일균 군(S 군) 89명과 혼합균 군(M 군) 6명의 두 군으로 나눠 후향적으로 임상 소견을 비교하였다. 비교 항목으로는 발열 일수, 말초 혈액 백혈구 수치와 C-반응 단백(CRP), 수신증, 방광 요관 역류, 신반흔 형성에 대한 비교를 분석하였다(수신증, 방광 요관 역류 및 신 반흔이 있으면= 1, 없으면= 0). 결과: 단일균 양성인 환아 그룹과 혼합균 양성인 환아 그룹에서 발열 일수(혼합균 vs 단일균 $4.7{\pm}3.1$ vs. $6{\pm}5.7$ days), 혈청 백혈구 수치(혼합균 vs 단일균 $18,630{\pm}6,483$ vs. $20,153{\pm}7,660/uL$)와 C-반응 단백 수치(혼합균 vs 단일균 $100.6{\pm}2.46$ vs. $81.1{\pm}0.09\;mg/L$), 수신증, 방광 요관 역류 그리고 신 반흔 모두 두 군간에 통계학적으로 유의한 차이가 없었다. 결론: 요로 감염 환아에서 요 배양 검사 상 혼합균 양성이 나온 경우 일반적으로 오염 균주로 생각하고 간과되기 쉬울 수 있으나, 진단 시 주의 깊게 해석하는 것이 필요할 것으로 사료된다. Purpose: We investigated the clinical presentation of febrile pediatric patients with acute pyelonephritis (APN) with a mixed urine culture from an aseptic urine sample, and compared with that of those with a single culture. Methods: We retrospectively reviewed the medical charts of 95 patients diagnosed as APN with fever between January 2008 and October 2010 at Korea University Medical Center. We classified the patients with APN into two groups with a positive single culture (S group) and a positive mixed culture (M group) from an aseptic urine sample of suprapubic bladder aspiration or urethral catheterization and compared the fever duration, laboratory markers such as serum white blood cell (WBC) counts and C-reactive protein (CRP) values in peripheral blood, and the presence of hydronephrosis, renal scar and vesicoureteral reflux (VUR) between the two groups (If presence of hydronephrosis, scar and VUR=1 and no=0). Results: Total pediatric patients with febrile APN were 95 patients, a positive S group was 89 patients and a positive M group was 6 patients. Fever duration (S vs. M, $4.7{\pm}3.1$ vs. $6{\pm}5.7$ days), serum WBC (S vs. M, $18,630{\pm}6,483$ vs. $20,153{\pm}7,660/{\mu}L$) and CRP (S vs. M, $100.6{\pm}2.46$ vs. $81.1{\pm}0.09\;mg/L$) values, and the presence of hydronephrosis, renal scar and VUR were not different between the two groups. Conclusion: Our data shows that there were no specific differences of clinical manifestation between a positive single urine culture and a positive mixed urine culture in pediatric APN. A mixed urine culture from an aseptic urine sample should be interpreted cautiously.

The aim of this report is to analyze the Occurring rate of damage at each region of head works and to clear its damaged mechanism, centering around the destroyed situations of head works along both Musim and Bochong Rivers suffered from the storm flood occurred on July 22, 1980. The results obtained from the investigation of 25 head works taken for samples are summarized as follows. 1. The occurring rate of damage at each region of head works showed the largest number of 100 percentage in the revetment and protected riverbed work respectively, in the order of the next largest number, 68 percentage in weir body, 56 percentage in apron and 36 percentage in bank. 2. The destructive damage of revetment influenced largely on sweeping bank away, and destructive sufferings of weir body and protected bed work affected on the destruction of apron, otherwise the destructive sufferings of apron reversely also acted on the- destruction of weirbody and protected bed work. In other hand, partial damage of weir body at the side of revetment is largely influenced by destructive sweeping away of bank. 3. It was showed that the destructive phenomena of weir body occurred largely at the part of concentrated flow and also had a deep relation with scoring by concentrated flow around upstream foundation of weir. 4. The suffered region of revetment is the down stream part just near weir body and the degree of damage is more severe at the curved part of bank that center of flow is concentrated.

목적 : 모든 조영증강검사 전 혈관의 셀라인 테스트로 인한 Swelling, 혈관 외 유출(Extravasation)의 부작용을 최소화 하는데 목적이 있다. 대상 및 방법 : 응급CT실에서 조영증강검사를 시행하는 환자를 대상으로 간호사가 가장 적정한 위치의 IV를 한 곳에 자동조영제주입기의 Extend tube를 3-way에 연결하고, 순차적으로 셀라인을 주입하여, Swelling된 환자를 기록하였다. 결과 : 조영증강검사를 시행한 환자의 swelling 또는 (Extravasation)될 수 있는 16명의 환자를 조영제 주입 전 셀라인 테스트로 발견하였고, 7,332명의 환자분들 중에 2명의 환자만이 검사 후 심각하지 않게 약간 부은 swelling정도를 나타내었다. 결론 : 조영증강검사를 하는 모든 환자의 간호사가 손등, 팔꿈치, 발, 정강이 기타 등등 무작위로 가장 적정한 위치의 IV를 확보한 환자의 조영제 주입 전 셀라인 주입 테스트로 환자혈관의 좋고, 나쁨의 상태를 파악할 수 있어 혈관이 약해 생기는 swelling이나 (Extravasation)등의 부작용을 줄일 수 있을 것으로 사료된다. Purpose : It is intended to minimize side effects, swelling and extravasation caused by saline test for blood vessel before all contrast-enhanced examinations. Participants and Methods : In patients for whom medical examination is performed at emergency CT room, the extend tubes were connected to 3-way of contrast auto-injector at a place where a nurse made IV with the most appropriate position, and saline was injected in sequence, and patients with swelling were recorded. Results : Among patients for whom a contrast-enhanced examined was performed, 16 patients in whom swelling or extravasation might occur were found out through saline test before contrast injection. And a level of slight swelling not serious was shown in just 2 out of 7,332 patients after examination. Conclusion : It is possible to figure out whether patients blood vessel is in good or bad condition by saline injection test before contrast injection into patients for whom nurses in charge of patients who undergo a contrast-enhanced examination ensure IV in the most appropriate position such as the back of hand, elbow, foot and shin randomly. Therefore, it is thought that side effects such as swelling or extravasation occurring due to weak blood vessel can be reduced.
