This study is to develop research models suitable for e-Customs Clearance Single Window and empirically analyze them in order to examine and verify factors affecting e-Customs Clearance system in Korea on the basis of previously-verified studies such as Technology Accept Model(TAM), Task-Technology Fit Model(TTF) and managing tool like a Plan-Do-Check-reAct(PDCA) Model. Among many factors, this paper comprehensively analyzes an acceptance factor, which is one of the factors affecting the implementation and performance of e-Customs Clearance Single Window, from the Information Technological context, the Public Administration Task context in the customs clearance office, and the quality management environmental context. The finding from this paper are four factors which affecting on the e-Customs Clearance Single Window. The planing phase's factors affecting on the Do, Check, reAct, use rate and effect. The doing phase's factors don't affecting on the Check, reAct, use rate and effect. The checking phase's factors affecting a little bit on the reAct and effect but don't affecting on use rate. The reActing phase's factors don't affecting on use rate, but affecting on the effect. The use rate of e-Customs Clearance Single Windows affecting on the effect a little bit. So we can say there are the correlation between IT acceptance and performance on the e-Customs Clearance Single Window.

장동일,이정호,전환돈,김중훈,Chang, Dong-Eil,Lee, Jung-Ho,Jun, Hwan-Don,Kim, Joong-Hoon 한국방재학회 2008 한국방재학회논문집 Vol.8 No.5

본 연구에서는 도로 측구에 매설된 우수관거와 함께 빗물받이 간격을 최적화하는 우수관거 최적 설계 모형을 제시하였다. 빗물받이 간격이 변화하면 각 측구에 대한 유역면적이 변화하게 되며, 각 측구로 유입되는 유량을 또한 변화시키게 된다. 각 측구로 유입되는 유량이 달라질 경우 하부에 매설된 우수관거의 필요용량이 달라지므로 관경의 변화가 요구되는 결과를 낳는다. 즉 빗물받이 간격이 달라진다면 빗물받이 개수, 각 우수관거의 관경 및 연장, 그리고 관거별 경사 등의 설계조합이 달라진다. 그에 따라서 최소비용을 위한 빗물받이 간격 별 우수관의 설계조합은 최적화를 통하여 해결해야한다. 수리학적 조건을 만족하는 빗물받이 간격 및 우수관의 설계조합을 유전자 알고리즘을 통하여 결정하였다. 도로의 조건들은 실제도로에 맞게 가정하였으며 강우조건은 서울지방의 재현기간 10년 지속시간 1시간 강우를 사용하였다. 현재 하수도 시설기준 및 여러 기준에 의해 포괄적으로 소개된 빗물받이 적정 간격은 $10{\sim}30\;m$이므로 본 모형을 이용한 빗물받이 최적 간격에 대한 해의 탐색은 이 범위 내에서 이루어졌다. 본 연구는 도로의 경사조건에 따른 빗물받이 최적간격과 우수관의 최적조합을 최소 건설비용을 통하여 제시하였으며 본 연구에 의해 획득된 결과에 의하면 노면경사에 따라 최적 빗물받이 간격이 다르며 빗물받이 간격에 따라 공사비용을최대 20% 감소시킬 수 있었다. This study presented a design model optimizing a distance of inlet with drainage pipe laid under the gutter in road. When the distance of inlet changed, a basin for the gutter divided by the distance of inlet and the inflow coming into the gutter would be changed. In this case, the change of inlet distance causes the change of a diameter of drainage pipe and slope because of the change of capacity. Therefore, the optimization is needed to design the combination of them for the distance of inlet. Genetic Algorithm is used to determine the optimal combination of them. The conditions of road and the precipitation were assumed like a real and the range of inlet distance adopted $10{\sim}30\;m$ which has been introduced in domestic. This model presented the optimal distance of inlet and the combination of pipe and slope through the minimum cost. The result of the study is that the optimal distance of inlet is different from each slope of road and it can reduce about 20% of total cost for the distance of inlet.

To assess the change in left ventricular function after hospital discharge, 57 patients with acute myocardial infarction were studied before discharge and 26 of them after discharge as well with either or both of treadmill test and radionuclide ventriculography(RNV). Follow-up study patients were 2g men with mean age of 53.1. Their infarct locations were anterior in 16 cases, inferior in 8 cases and anterior and inferior in 2 cases; 21 cases were in Killip class I, 3 cases in II, and 2 cases in III. Follow-up study was performed 2~19 months(mean 7.3 months) after acute myocardial infarction. The results were as follows: 1) Predischarge study showed that a relationship is present between regional wall motion abnormality, Killip class, peak serum CK and left ventricular ejection fraction(LVEF). 2) Predischarge and follow-up treadmill tests showed no significant change. 3) Follow-up RNV showed worsening of regional wall motion only in 1 case: Other cases showed either improvement or no change in regional wall motion. 4) Overall patients showed a significant increase in LVEF on follow-up. By location, only anterior infarction showed a significant increase in LVEF. 5) Killip class I patients showed a significant increase in LVEF on follow-up. 6) Most cases in this study were uncomplicated myocardial infarction and they showed improved LV function(suggested by RNV) on follow-up. Treadmill test also seems to be valuable for evaluationg improvement in exercise capacity on follow-up. So it is recomended that treadmill test or RNV be performed after discharge to evaluate change in LV function objectively.

저자들은 만성췌장염환자에서 지속적인 오심과 구토를 주소로 내원하여 십이지장협착으로 진단된 1예를 경험하였기에 보고하는 바이다. Duodenal stenosis resulting from fibroinflammatory process is a rare complication of chronic pancreatitis. The mechanism of duodenal stenosis seems to be related to ischemia and edema caused by persistent inflammation, which results in irreversible change of duodenal wall structure. We experienced a chronic alcoholic male patient with duodenal stenosis who had a history of choledochojejunostomy to relieve distal bile duct stenosis several years ago. He had suffered persistent postprandial nausea and vomiting for several months. Barium study of upper gastrointestinal tract and repeated endoscopy show narrowing lumen of duodenum with coarse nodular surface due to reactive inflammatory change.

Splenic abscess is a rare illness. Its incidence has ranged from 0.14 to 0.7 % in various autopsies conducted in the US. Even in the most recently published articles, diagnosis was made only in autopsies in 37 % of the cases. While splenic abscess may arise occasionally from contiguous spread of infection or direct trauma to the spleen, usually it develops with hematogenous spread or infection. But, bacterial endocarditis is the most common cause. RUQ pain of abdomen developed in only half of series. Splenomegaly, fever and leucocytosis was also present. When splenic abscesses are being considered in a differential diagnosis, CT scan of the abdomen has been the most sensitive diagnostic tool. Streptococcal species are the most common bacterial isolates from splenic abscesses, S. aureus is the next most common. Salmonella species are seen commonly in patients with sickle cell hemoglobinopathy. Because of the high mortality related for splenic abscess, the treatment of choice is splenectomy with adjunctive antibiotics. However, percutaneous drainage has been successful alternative. We reported a 19-years old female patient who had splenic abscess after remission induction chemotherapy of acute leukemia, successfully treated with splenectomy.

Otitis media with effusion (OME) is one of the most common disease in children but its pathogenesis is not clear. In particular the role of allergy has revealed conflicting support with widely varing opinions as to its importance. Within recent years, striking biochemical and immunochemical analytic techniques have opened a new approach the study of otitis media with effusion. So we focused on distributions of IgE in adenoid tissue and serum IgE levels. Authors compared the serum IgE and the distribution of IgE in adenoid tissue between the 20 patients underwent tonsillectomy, adenoidectomy and ventilating tube insertion and control group of 11 patients underwent tonsillectomy and adenoidectomy. The results were as follows; 1. In the distribution of IgE in adenoid tissue, there was a significant increase in the group of patients with OME compared to the control group (P<0.01). 2. In the analysis of serum IgE levels, the levels of IgE in the OME patients an control group were higher than normal level, although the level of IgE in the OME patients were less than that of control group, there was no significance P>0.05).

Idiopathic hypereosinophilic syndrome is characterized by marked elevation of eosinophil count ( >1,500/㎣) in peripheral blood without explaining etiology. It shows tissue involvement in many organs such as liver, G-I tract, myocar dium, lung, skin, kidney and nerve. Some case of hypereosinophilic syndrome with hepatic involvement have been reported, but not much. We have recently experienced a case with idiopathic hypereosinophilic syndrome of a 40 year old man who presented with RUQ pain. By abdominal CT, ill- defined subcapsular hematoma was detected. Liver biopsy showed eosinophilic infiltration within the portal tract and sinusoid. Drain procedure and corticosteroid adminiiatbrought marked improvement of clinical manifestation, hematologic abnormality and radiologic abnormality.

This research was conducted as a fundamental study to apply tailored blank welding technique into automotive production process. The materials used in this study were 2.0mm thickness low carbon steel sheets and 1.2mm Zn-coated low carbon steel sheets. To ensure the reproducibility and to consider various factors, experiments were conducted by applying Taguchi experimental method with 6 factors. Every welding process was repeated 3 times to offset the effect of uncontrolled factors. Elongation and LDH(Limited Dome Height) were measured to evaluate formability of specimens and Optical microscopy, XRD, SEM, and EDS analysis were performed to observe the microstructures and to determine the solidification mode in the weld. The elongation of specimen welded with optimum condition was 83% of base metal, and LDH was 84% of base metal. In case of laser treated specimen where Zn coating was removed, elongation was 85% of base metal, and LDH was 85% of base metal. In fusion zone, phases were consisted of quasi-polygonal ferrite, banitic ferrite, and martensite.
