Purpose: This study was conducted to investigate the effect of body mass index (BMI) and abdominal circumference (AC) on the diagnosis of appendicitis using ultrasonography (US). Methods: Between January 1, 2007, and June 30, 2007, we recruited 170 patients who complained about right lower-quadrant pain and who had an Alvarado score greater than 7 points. We recorded the height, weight, and AC for each patient and calculated a BMI. All patients received US investigation by emergency department residents. The cases were categorized according to whether the appendicitis was visible or non-visible. The sensitivity, specificity, and accuracy for each group were assessed and compared. Results: A total of 170 patients was enrolled. Of those 94 patients had visible signs of appendicitis, and 76 patients had non-visible appendicitis. The mean BMI and AC of visible group were 22.09±3.12 and 77.47±9.32, as compared with 22.43±4.05 and 83.83±9.48 for the non-visible group, and the groups had significant differences in BMI and AC (p<0.001). The sensitivity, specificity and accuracy of US in patients with BMI under 25 were 58%, 60%, and 58%, respectively, and for those with BMI over 25 were 35%, 50%, and 36%. The sensitivity, specificity, and accuracy of US for male patients with AC under 90 cm were 55%, 75%, and 56%, and for those with AC over 90 cm the numbers were 35%, 50%, and 33%. The sensitivity, specificity, and accuracy of US in females with AC under 80 cm were 75%, 75%, and 74% and for those with AC over 80 cm, 45%, 50%, and 47%. Conclusion: Increasing BMI and AC negatively affect the US sensitivity, specificity, and accuracy in an appendicitis diagnosis.

우리나라에서 가축 사육밀도가 가장 높고 오리농법을 가장 대규모로 실시하고 있는 충남 홍성군 홍동면, 장곡면의 흥동저수지 유역을 사례지역으로 선정하여 오리농법에 의한 벼 재배가 지역 환경과 주변 수질에 미치는 영향을 밝히고 이를 바탕으로 친환경농업의 달성을 위한 올바른 발전방안을 제시코자 오리농법에 의한 벼 재배가 토양 환경과 주변 수질에 미치는 영향을 분석하였다. 오리농법 실시 논의 토양화학성은 벼농사를 위한 적정범위 안에 있었지만 일반농법 실시 논보다 유기물 함량과 유효인산 함량이 높아 오리농법 실시 논의 양분투입량이 상대적으로 많은 것으로 추정되어 지속농업의 달성을 위해서는 적정량의 퇴비나 유기질비료의 시용이 요구됨을 알 수 있었다. 조사지역 하천수의 수질은 T-N, T-P, COD 값들이 높아 상당히 인근의 하천들이 오염되었음을 나타내고 있으며, T-N, T-P, COD 등으로 평가한 수질의 오염도가 논으로부터 비료성분의 유출 가능성과 일치한 결과로 볼 때 이 지역의 하천수가 벼재배에 의해 배출되는 오염물질의 영향을 일정부분 받고 있는 것으로 평가될 수 있었다. 오리농법 실시 논의 표면수 수질은 일반농법 실시 논보다 EC는 135.7%, COD는 220.1%, T-N는 172.0%, T-P는 227.9%가 높았으며 특히, COD와 T-P는 2배 이상이 높았으며 오리의 활동에 의해 발생하는 물의 탁도와 유의성 있는 상관관계를 보여 오리농법에 의한 벼 재배는 일반농법에 의한 벼 재배 방법보다 논물유출에 의한 잠재 수질오염 가능성이 큰 것으로 평가되었다. 따라서 오리농법 실시 논은 논물 유출에 의한 주변 수질오염 방지를 위해 더욱 철저한 물꼬관리가 필요한 것으로 판단되었다. To clarify the impact of the rice-duck farming system on the regional environment and the surrounding, a case study was carried out at Hongdong Reservoir valley of Hongdong-myeon and Janggok-myeon, Hongseong-gun, Chungcheongnam-do where the density of livestock grazing is the highest and rice cultivation with the rice-duck farming system is extensively practiced. The soil characteristics and water qualities at paddy fields were compared between two rice cultivation methods of rice-duck farming system and conventional farming system. The organic matters and available phosphate contents in soil of paddy fields where the rice-duck farming system was practiced were higher than those of paddy fields where conventional farming system was practiced. However, the available phosphate content was lower than the optimum for rice cultivation and the mean concentration of paddy soil in Korea. The surface water quality of the paddy field with the rice-duck farming system was practiced had higher EC (137 %), $COD_{Cr}$ (220 %), T-N (172 %), and T-P (226 %) contents than that with the conventional farming system was practiced. Especially, $COD_{Cr}$ and T-P were more than 2 times higher, which tells that the possibility of water pollution by drainage water of paddy field is higher in the paddy fields with the rice-duck farming system practiced than in those with the conventional farming practiced. The higher contents of T-P and $COD_{Cr}$ in surface water at the paddy field of rice-duck farming system practiced were directly caused by soil particles in the muddy water. Consequently, it is necessary to thoroughly manage the irrigation and drainage system of rice-duck farming system practiced to prevent outflow of surface water from paddy and pollution of surrounding water system.

Background: Contrast-enhanced Abdominopelvic Computed Tomography(CT) is widely used for diagnosing abdominal injuries after blunt trauma. The purpose of this retrospective study is to classify the contrast-enhanced Abdominopelvic CT finding of mesenteric injuries after blunt abdominal trauma and assess of CT finding on clinical management. Methods: Between January 2000 and December 2003, 607 consecutive spiral abdomonopelvic CT examinations were performed in the ER of Gil medical center after blunt abdominal trauma. CT represented mesenteric injuries : bowel wall thickening or hematoma, mesenteric haziness or fatty infiltration, confined fluid or hematoma within mesenteric folds. We classified patients into 5 Grade by the hematoma size on CT scans : Grade I(None, 0 mm), II(Minimal, ≤10 mm), III(Small, 11~30mm), IV(Moderate, 31~60 mm), V(Large, ≥61 mm). Results: On the basis of the CT findings, 42 of the 607 patients were selected. 18 (42.9%) of 42 patients were classified as having grade I, II, III (≤30 mm) and 24 (57.1%) of 42 patients as having grade IV, V(≥31 mm). Of the 18 patients with grade I, II, III, 16(88.9%) were managed conservatively, while 2(11.1%) underwent surgery. of the 24 patients with grade IV, V injuries, 20(83.3%) were treated surgically and 4(16.7%) patients were managed conservatively. Conclusions: It is sufficient to treat of grade I, II, III mesenteric injuries by conservative management. It should be considered emergency operation to treatment of grade IV, V mesenteric injuries. (p<0.001) There were no relations between grading and initial systolic blood pressure, initial blood pressure and operation.

To establish the best rice cultivating system in the aspects of environment-loving agriculture, the amounts and patterns of nitrogen leached in the paddy soil were investigated with 7 treatments; Recommendation(R), Farmer`s usual practice(FUP), Straw compost+chemical fertilizers reduced(SCF), Fresh straw+recommendation(FSC), Fresh cow manure(FCM), Cow manure compost(CMC), and no fertilization as Control(C). And SCF, FCM and CMC were applied with same amounts of total nitrogen to R. The infiltrated water samples were collected in ceramic porous cups which were buried at 60㎝ depth from the top. Concentrations of nitrate-N in irrigated water were 1.3㎎ ℓ^(-1) on rice transplanting season when nutrients began to elute from paddy soil, and 0.4㎎ ℓ^(-1) after breaking off irrigation. But it was 4-6㎎ ℓ^(-1) in rice growing period. The maximum concentration of nitrate-N in leachate was not more than 7㎎ ℓ^(-1) during rice cultivation. The amounts of nitrogen leached in R, FUP, SCF, FSR, FCM, CMC and C were 59, 63, 25, 41, 24, 27, 17㎏ ㏊^(-1)y^(-1) respectively. Nitrogen leaching was decreased to about 30% by supplement of fresh rice straw(FSC) to R. Furthermore, it was possible to reduce to over 50% of nitrogen leaching by reducing chemical fertilizer application(CF), or by substituting of chemical fertilizers with fresh cow manure(FCM) or cow manure compost(CMC). In added organic fertilizer treatments, the amounts of infiltrated nitrogen were less 13-46㎏ ㏊^(-1)y^(-1) than that of input by irrigation. This experiment showed that nutrients leaching was minimized by substitution of chemical fertilizers with organic fertilizer or by application of straw with chemical fertilizers in rice paddy soil and rice cultivation with suitable fertilizer management can work as a purifier rather than contaminator of water.
