This study aims to investigate the actual extracurricular education and economic strains of households. For these purposes, 372 households in Kwangju with students but collegians were surveyed through the questionnaire method. The frequency, percentile, One-way ANOVA in GLM and Chi-square test were used for the data analysis. The Results were as follows: 1. Most of households takes extracurricular lessons(334) and be willing to do (268). Many have concerns about it and need it. 2. The average lesson number is 2 subject and average cost per household is 177,000 won. 3. The average economic strains due to the extracurricular cost is 22 points. Economic strains differ according to the socio-economic variables (e. g. father's educational level, mother's educational level, average income level per month, and to the attitude variables, extracurricular will in future, parent concerns, and needs. Here we can conclude, many households have economic strains due to extracurricular fees. And the economic strains by extracurricular lessons are so undesirable to family growth and development that government have to reform the educational structure. So the social need to the extracurricular lesson will be taken away. But in reality, still extracurricular lessons are so needed that the households must have any strategies to face the economic strains.

Bisthmus 제재와 항생제의 복합 투여가 Helicobactor pylori 박멸과 재발에 미치는 영향

김선주,황성규,박상흠,이문호 순천향대학교 1994 논문집 Vol.17 No.4

위점막내에 존재하는 Helicobacter pylori는 소화성 궤양의 발생과 재발에 중요한 인자로 인식되고 있으며, bisthmus, metronidazole, amoxicillin을 포함하는 3제 병합요법을 시행하면 H. pylori균의 박멸에 유효하고 소화성 궤양 재발 빈도를 낮출 수 있다고 한다. 그러나 3제 병합요법은 부작용 발생율이 높아 치료 실패의 주원인이 되고 있다. 이에 저자등은 H. pylori 양성인 소화성 궤양환자에서 H₂ 길항제 투여와 함께 3제 병합요법을 시행하였고, 또한 비교적 약제 부작용이 많은 metronidazole을 제외한 이제 병합 요법을 시행하여 H₂ 길항제 단독 투여한 대조군과 6개월간 추적하여 균의 박멸및 재발 여부를 비교 관찰하였다. 대조군은 Nizatidine을 8주간 투여하였으며 치료 1군은 nizatidine(150mg 하루 2회 복용)을 8주간 투여하고 첫 2주간은 TDB(240mg 하루 2회 복용), amoxicilline(500mg 하루 4회 복용) 투여하였다. 치료 2군은 nizatidine(150mg 하루 2회 복용)을 8주간 투여하고 첫 2주간은 TDB(240mg 하루 2회 복용)과 amoxicilline(500mg 하루 4회복용) metronidazole (250mg thrice a day)을 투여하였다. 치료 8주후 치료 1군은 53%에서, 치료 2군은 100%에서 균이 음전되었으나 대조군은 1예도 음전되지 않았다. 치료 2군의 13%에서 약물에 의한 부작용이 관찰되었다. 치료 6개월 추적 검사시 대조군은 모두 H. pylori 감염이 지속되었으며 치료 1군에서는 63%에서 재발하였으며, 치료 2군에서는 15%에서 재발하였다. 대조군에서는 소화성 궤양(위궤양 1명, 십이지장 궤양 4명)이 5명에서 재발하였으나 치료군에서는 재발이 없었다. H. pylori박멸된 환자에서의 항 H.pylori 항체(IgG)가는 치료 6개월에 치료전의 40%로 감소한 반면, 대조군의 항체가는 변화가 없었다. 이상의 결과로 H₂ 길항제(nizatidine)을 metronidazole 750mg/day, TDB 480mg/day, amoxicillin 2.0gm/day를 2주간 투여하면 약제에 의한 합병증이 비교적 적고, Helicobacter pylori 박멸과 재발 방지에 효과적이며 혈청 H. pylori 항체(IgG)의 추적 검사는 항 H. pylori 치료후 균박멸의 추적검사에 유용함을 알 수 있었다. It has recently been recognized that Helicobacter pylori is a important factor in the development and the recurrence of peptic ulcer diseases. Several studies has been shown that the eradication of Helicobacter pylori is associated with considerable reduction in the the rate of recurrence of peptic ulcer. Triple therapy including bisthmus, amoxicillin, metronidazole is known to be useful in the eradication of Helicobacter pylori, but relatively frequent side effects are a major problem. This study was performed to evaluate the clinical course and the efficacy of triple therapy with H₂ blocker and bisthmus plus amoxicillin therpy with H₂ blocker in the eradication and the recurrence of Helicobacter pylori at 8 weeks and 6 months of treatment. Forty five patients with peptic ulcer disease with a positive urease test of the gastric mucosa were enrolled and assigned to receive H₂ blocker (nizatidine 150mg twice a day) for 8 weeks(control group), tripottasium dicitrato bismuthate 240mg twice a day and amoxicillin 500mg four times a day for 2 weeks, nizatidine for 8 weeks (treatment group Ⅰ), tripottasium dicitrato bismuthate 240mg twice a day and amoxicillin 500mg four times a day, metronidazole 250mg thrice a day for 2 weeks, nizatidine for 8 weeks(treatment group Ⅱ). H. pylori was eradicated in 53% of treatment group Ⅰ, 100% of treatment group Ⅱ, none of control group after 8 weeks of treatment. Helicobacter pylori infection is recurred in 63% of of treatment group Ⅰ and 15% of treatment group Ⅱ. Side effects were recorded in 3 patients(2 patients on treatment group Ⅱ, 1 patient on treatment group Ⅰ), but it were minor side effects. No patients on treatment groups recurred peptic ulcer disease, while 5 patients on control group. Anti-H. pylori antibody IgG remained constant in bacteria positive control group, but in patients in whom H. pylori had been eradicated serum antibody titers fell significantly at 6 months of treatment. In conclusion, triple therapy including a low dose metronidazole with nizatidine is effective on the eradication of Helicobacter pylori infection and reduced the rate of side effects. Bisthmus and amoxicillin with nizatidine is not effective on the eradication and the recurrence of Helicobactor pylori infection. Serologic tests for H. pylori are reliable means of monitoring success of eradication of H. pylori.

Finite strip method, developed by Cheung to improve the finite element method, uses trigonometric series as longitudinal interpolation functions. Although this method is useful and highly accurate for simple structures, it cannot be used for structures with complex boundary conditions. The objective of this study is to get rid of this effect of finite strip method using B-spline functions as displacement functions in analyzing plates. Stiffness matrices are derived using principle of minimum total potential energy for a plate element. An algorithm is developed and applied to plate with various boundary conditions. To demonstrate the accuracy and versatility of developed method, the results of the method were compared with those from the closed-from solution and the finite element method. As a result, the presented method is proved to be more accurate and economical than the finite element method, and applicable to plates with complex boundary conditions.

Half space problems of structural system, which are usually solved using simple truncation of far field or using analytical far field solution, are considered using infinite elements. Among the infinite elements previously developed, a mapped infinite element is adopted and implemented in a finite element code which can handle two dimensional problems. Implemented program is applied to a cavity problem subject to internal pressure. The resulting solutions are compared with boundary element solutions due to Brebbia. In addition, conventional finite element analyses with simple truncation are carried out to compare the efficiency and accuracy of the developed program. The results show that the developed program renders accurate solutions which are close to the known values. Also, it can be seen that the developed program requires a smaller number of elements, so as shorter computing time than the conventional finite element codes, to get the same degree of accuracy.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

Moon Joo Hwang,Kyeong Ok Kim,A Lim Kim,Si Hyung Lee,Byung Ik Jang,Tae Nyeun Kim 대한장연구학회 2018 Intestinal Research Vol.16 No.3

Background/Aims: We aimed to assess the rate of histologic discrepancy (HD) between endoscopic forceps biopsy (EFB) and totally resected specimens in colorectal polyp and analyze the risk factors of discordant group, especially under-diagnosis (UD) cases before complete removal of colorectal polyp. Methods: From 2010 to 2015, a total of 290 polyps in 210 patients which had baseline pathology report before endoscopic resection (ER) were analyzed. UD cases were defined as those in which the diagnosis changed to a more advanced histologic feature after ER. Results: A change in the final histology after ER was noted in 137 cases (47.2%), and after excluding 9 insignificant cases, 128 cases were further categorized into over-diagnosed and under-diagnosed group. UD occurred in 86 cases (29.7%) and change from benign to malignancy was noted in 26 cases (8.9%). On univariate analysis, a larger polyp size (>10 mm) was significantly associated with both HD (P<0.001) and UD (P<0.001). Regarding polyp morphology, protruding or flat was not significantly important. On multivariate analysis, polyp size >10 mm was the single most significant predictor of both HD (P<0.001) and UD (P<0.001). Conclusions: The HD and UD rates were 47.2% and 29.7%, respectively. Polyp size >10 mm was the most important predictor of both HD and UD. We should be careful in making treatment strategy of colorectal polyp based on histologic report of EFB especially when the size of polyp is >10 mm.

Severe acute pancreatitis occurs in about 20% of patients with acute pancreatitis and can be associated with multiorgan failure. Acute renal failure caused by severe acute pancreatitis not only aggravates pancreatitis but also increases patient mortality. Peritoneal exudate contains many toxic substances such as amylase, lipase, phospholipase-A, trypsinogen, prostaglandins, kinin forming enzymes, and histamine releasing factor. Upon entering the circulation, these substances can cause complications, which are responsible for the majority of early deaths. This said, peritoneal dialysis is indicated to remove toxic materials from the peritoneal cavity and to manage acute renal failure. We report three acute peritoneal dialysis cases in acute renal failure associated with severe acute pancreatitis.
