N/A In 938 patients suspected of having pancreatic or biliary tract disease, 104 patients were shown to have biliary tract cancer demonstrated by endoscopic retrograde cholangiopancreatography, at kwangju christian hospital from Sep, 1971j to Aug, 1982. Authors analyzed the biliary tract cancer and compared them with the final diagnosis, The results were as follow 1) There were 41 cases of primary CBD ca and 19 cases(46.3%) of them were located in upper portion of CBD. In CBD cancer, stenosis of CBD(58. 5%) were more common than obstructive type(41. 5%) by ERCP. Male and female ratio was 2.2: 1 and 6th decade were most common. 2) There were 5 cases of primary GB cancer. Four of them were diagnosed by ERCP and remainer were by ERCP. In all cases, liver metastasis was suspected by liver scanning. 3) There were 14 cases of primary ampulla of Vater cancer. All of them were diagnosed by ERCP except one and female(9) was more common than male(5) In 6 cases of them, liver metastasis was suspected by liver scanning and prognosis was better than other biliary tract cancer. 4) There were 22 cases of infiltrative obstructive ampullary cancer and 16 cases of them were from pancreas cancer and male(17) was more common than female(5).Nearly all of them were not indicated for surgical treatment 5) There were 22 cases of metastatic biliary due to early distant metastasis. Tract cancer and in all cases, their primary foci were pancreas and 13 cases of them were male. Most common metastatic site of biliary tract was upper portion of CBC(18) and in all cases, liver metastasis was also demonstrated by liver scanning.

N/A ERCP has some advantages in the diagnosis of pancreatic cyst. One is that ERCP can find the ultrasonographically undetectable cyst which is less than 5 cm located in the left upper quadrant. Also ERCP provides the information about the ductal anatomy underlying diseases of pancreatic cyst. Authors report the clinical study S: ERCP finding of 10 cases of pancreatic cyst. The results were as follows 1) Out of 938 cases of ERCP, the pancreatic cysts were 10 cases and 1 case was mucinoous cystadenoma of pancreas and others were pseudocysts. 2) The etiologic causes of pancreatic pseudocysts were acute and chronic pancreatitis(4 cases) malignancy(2 cases) trauma(1 case) and unknown(2 cases). 3) There is no specific age-incidence and male to female ratio was 4: 1 4) The most common site of pseudocyst was tail and the mucinous cystadenoma was located in the head. 5) The most common chief complaints were upper abdominal pain & palpable abdominal mass and serum amylase was elevated in 4 cases & leukocytosis in 3 cases. 6) The diagnosis by UGI-series was pancreatic cyst(3 cases), retroperitoneal tumor(2 cases) normal(2 cases) and by G.I echo, pancreatic cyst(4 cases) retroperitoneal cystic tumor(1 case) & normal(1 case). 7) The complication after ERCP is absent except mild transient elevation of serum amylase 8) The complications of pancreatic pseudocyst were infection(2 cases) k retroperitoneal rupture(1 case) and tbe frequency rate was 33% 9) The ERCP finding was variable. In 5 cases, we have demonstrated the communication from the pancreatic duct system to the cyst with the filling of dye and they are small cysts located in the parenchyme. Other findings were the displacement & compression defect of CBD by the head cyst and the complete obstruction, stenosis and displacement of the pancreatic duct
소규모 농업유역에서 질소와 인의 하천 부하에 대한 AGNPS 모형의 적용

우리 나라의 농업지대 소유역에서 질소와 인의 부하에 대한 농업비점오염 모형 AGNPS의 적용 가능성을 검토하고자 경북 영천군 임고천 유역에서 조사된 실제 강우사상에 대하여 강우사상별로 실측치와 모형의 예측치를 비교하였다. CN 식에 대한 보정을 거친 모형을 적용한 결과, 첨두유량은 강우에 따라 다소 차이는 있었으나 예측치는 모형효율 0.97로 실측치와 거의 일치하였다. 이는 유역의 특성을 고려하여 CN 식을 수정하였고 유역의 동질성을 위해 격자망을 비교적 세분화하였기 때문으로 판단된다. 총 질소와 총인 농도의 경우의 실측치와 예측치를 비교하면 모형효율은 각각 0.93과 0.74였으며, 총인의 경우 총질소에 비해 결정계수가 비교적 낮은 것은 토지 이용에 따른 시비 및 생활 및 축산 오수 유입 등의 차이에 상대적으로 민감하게 영향을 받았기 때문으로 판단된다. 농업비점오염 부하를 예측하는 모형인 AGNPS는 적용 대상 유역의 특성을 잘 고려하여 매개변수들을 적절히 보정하고 정확한 입력자료를 확보하면 우리나라 소규모 농업 유역에서도 활용될 수 있을 것으로 판단된다. The event-based agricultural non-point source(AGNPS) pollution model was applied to estimate the loads of nitrogen and phosphorus in a stream draining small agricultural watersheds. Calibration and verification of the model were performed using observed data collected from rainfall events in the Imgo watersheds during 1997-1998. Parameter calibrations were made for the runoff curve number. The peak flow volumes in the watersheds were well reproduced by the modified model. Average deviation between observed and simulated values was 10%, and this match was confirmed by the coefficient of efficiency value of 0.97. The deviations tended to increase as the peak flows increased. The simulated total N concentrations in the stream water were fairly close to the measured values, and the coefficient of efficiency in the estimation was 0.93. However, there were relatively large variations between calculated and observed values of total P concentration, and the coefficient of efficiency in the estimation was 0.74. Any inaccuracies that arise in estimating runoff flow and nutrient loading can not be explained exactly and further adjustment and refinements may be needed for application of AGNPS in agricultural watersheds. With this restrictions in mind, it can be concluded that AGNPS can provide realistic estimates of nonpoint source nutrient yields.
