Objectives : The purpose of this study is to infer the prescription effectiveness that have not been recorded in the existing effectiveness and to find out how to classify. Methods : The herbal compositions of bang-yaghabpyeon, the herbal textbooks and contents related to the prescription textbooks' effectiveness were entered into the database using the 'Access 2014 of the MS'. The effectiveness are inferred using query sentences. Results : The prescription effectiveness in the bang-yaghabpyeon were inferred using the herbal classification, herbal effectiveness and herbal effectiveness inferred from prescription textbooks. Conclusions : Each information of herbal effectiveness strength was extracted using the prescription textbooks' effectiveness information. These results were efficient to infer and classify bang-yaghabpyeon prescription effectiveness.

Background: Eradication of Helicobacter pylori infection with triple therapy (TT) hasbeen reported to achieve unacceptable rates in Korea. Sequential therapy (ST) and concomitant therapy (CT) has been suggested as alternatives to the TT regimen. The aim of this study was to compare the effi cacy of ST and CT with that of TT in Korea. Methods: For this multicentre, randomized trial, patients (=20 years of age) with H. pylori infection from 5 centers in Korea were recruited. Patients were randomly allocated to TT (PPI, amoxicillin and clarithromycin for 10 days), ST (PPI and amoxicillin for the fi rst 5 days, followed by PPI, clarithromycin and metronidazole for the next 5 days) or CT (PPI, amoxicillin, clarithromycin and metronidazole for 10 days). The primary outcome was the eradication rate of each treatment by intention-to-treat (ITT) and per-protocol (PP) analysis. Results: From March, 2013 a total of 151 patients were enrolled in our study. Sixty one patients were allocated to the TT, 49 patients to CT group, and 29 patients to the ST group. For ITT analysis, the eradication rates of TT, ST and CT were 67.2% (41/61), 59.2% (29/49), 68.3% (28/41), respectively. For PP analysis, the eradication rates were 91.1% (41/45), 82.9% (29/35), 93.3% (28/30), respectively. We recorded no signifi cant difference in the occurrence of adverse effects or in compliance between the three groups. Conclusions: TT and CT regimens seem to achieve higher eradication rates than the ST regimen in Korea. Additional study results from more patients are expected.

Concrete infill and reinforcement are one of the most well-known strengthening methods of structural elements. This study investigated flexural performance of concrete infill composite PHC pile (ICP pile) reinforced by infill concrete and longitudinal rebars in hollow PHC pile. A total four series of pile specimens were tested by four points bending method under simply supported conditions and investigated bending moment experimentally and analytically. From the test results, it was found that although reinforcement of infilled concrete on the pure bending moment of PHC pile was negligible, reinforcement of PHC pile using infilled concrete and longitudinal rebars increase the maximum bending moment with range from 1.95 to 2.31 times than that of conventional PHC pile. The error of bending moment between experimental results and predicted results by nonlinear sectional analysis on the basis of the conventional layered sectional approach was in the range of -2.54 % to 2.80 %. The axial compression and moment interaction analysis for ICP piles shows more significant strengthening effects of infilled concrete and longitudinal rebars.

Purpose: Improved survival of patients with childhood acute lymphoblastic leukemia (ALL) has drawn attention to the potential for late consequences of previous treatments among survivors, including metabolic syndrome. In this study, we evaluated changes in 3 parameters, namely, random blood glucose, body mass index (BMI), and Z score for BMI (Z-BMI), in children with ALL during chemotherapy and after completion of treatment. Methods: Patients newly diagnosed with ALL from January, 2005 to December, 2008 at Saint Mary's Hospital, The Catholic University of Korea, who completed treatment with chemotherapy only were included (n=107). Random glucose, BMI, and Z-BMI were recorded at 5 intervals: at diagnosis, before maintenance treatment, at completion of maintenance treatment, and 6 and 12 months after completion of maintenance treatment. Similar analyses were conducted on 2 subcohorts based on ALL risk groups. Results: For random glucose, a paired comparison showed significantly lower levels at 12 months post-treatment compared to those at initial diagnosis ($P$ <0.001) and before maintenance ($P$ <0.001). The Z-BMI score was significantly higher before maintenance than at diagnosis ($P$ <0.001), but decreased significantly at the end of treatment ($P$ <0.001) and remained low at 6 months ($P$ <0.001) and 12 months ($P$ <0.001) post-treatment. Similar results were obtained upon analysis of risk group-based subcohorts. Conclusion: For a cohort of ALL patients treated without allogeneic transplantation or cranial irradiation, decrease in random glucose and Z-BMI after completion of chemotherapy does not indicate future glucose intolerance or obesity.

<P>Mechanical tests were carried out to evaluate the influence and effects of fluidity and compressive strength of cement grout on semirigid asphalt pavement. An open graded asphalt skeleton was designed in order to achieve target porosity in the range of 18~22%. In addition, four types of cement grout mixtures were produced with varying mix proportions with ultrarapid hardening cement and chemical admixtures, that is, accelerating and retarding agents. For the semirigid pavement specimens, mechanical experiments to measure properties such as porosity, flexural strength, Marshall stability, and wheel tracking resistance were carried out. The test results demonstrated that the flow time (fluidity) of cement grout is the most significant factor that determines the mechanical properties of semirigid asphalt specimens under constant condition of the open graded asphalt skeleton. For the semirigid pavement mixing proportion in the current study, it is recommended that the porosity of the open graded asphalt skeleton and flow time of cement grout should be 20% and within 12 seconds, respectively.</P>

To evaluate the variability of pulmonary function test, we measured individual coefficient of variation and significance level of spirometry in 16 normal subjects and 12 patients with obstructive pulmonary disease. The results were as follows; 1) In normal subjects, individual coefficient of variation of FVC, FEV1, FEF 25~75%. within a day were 2.05%, 1.97%, 5.80% and significance levels were 3%, 3%, 10%. 2) In patients, individual coefficint of variation of FVC. FEV1, FEF 25~75% within a day were 4.76%, 3.86%, 6.32% and significance levels were 8%, 6%, 10%. 3) In normal subjects, individual coefficient of FVC, FEV1, FEF 25~75% at an interval of two months were 1.71%, 1,66%, 3.83% and significance level were 3%, 3%, 6%.
