Using the sludge water in producing ready mixed concrete, which is generated as washing surplus concrete after completing manufacturing and transportation of concrete is the best method in meeting the issue of cost of production and environment. However, in reality, using sludge water decreases Quality, and solid ingredients adhere to the transportation line of sludge water and the basin of sludge water, agitated to prevent precipitation of sludge, which incurs tremendous amount of repair expenses. In order to resolve the problems above, we have studied stable methods of supplying sludge water and experimentally reviewed the types of facilities. The result showed that a facility that added stabilizing agents which retarded hydration of unhydrated cement in sludge water for certain periods (2-3 days) and simultaneously agitated and moved by air diffusion and vertical flat blade impeller was most effective in stabilizing concentration of solid and preventing precipitation of solid in the bottom of basin. In addition, the performance of agitation and prevention of adherence of reaction basin of sludge water depended on selective efficiency of sand grain, and it has been studied that buffering inconsistent band of circulation of sludge water by operating the ring blower for air diffusion to the maximum was advantageous to preventing managing concentration and prevention of adherence.

This paper addresses a new feature map building method that can minimizes the appearance of phantom features by using only sparse sonar data. The approach is composed of extraction of features and building a probability grid map using only the footprint of sparse sonar data, estimation of position uncertainty of the feature, and evaluation of the reliable features. A virtual circle association frame model has been developed, which associates two sonar footprints into a virtual circle frame. Using this model, geometric primitives such as line, point, or arc features are separately extracted. While extracting the feature, a grid map is also built using the orientation probability approach. Position uncertainty of each extracted feature is, then, estimated by considering both the position uncertainty of the robot and the measurement uncertainty of the sonar sensor. Finally, the reliable features among all extracted ones are evaluated from grid association method. The proposed methods have been tested in a real home environment with a mobile robot.

Recently, Most enterprises produced ready mixed concrete uses a mixing water as a recycling water without a density control in proportion to guide and standard. That is a cause of deterioration in the concrete quality like a reduce of strength, laitance, crack, etc. This study shows basic materials for development of ready mixed concrete recycling water density control system that holds down a deterioration in the concrete quality by using a mixed water treated recycling water with stabilizing agent and examines a possibility of re-using components of cement in recycling water. Therefore, in the experiment, we make a recycling water contains 3,5,7% of solid content ratio examines a property of a mixing water with a stabilizing agent and without it. Results of this study is next as follow. 1. The slump is decreased 1~2cm in a mixing without a stabilizing agent and the mixing with a stabilizing agent is similar to the standard mixing. 2. The air content is 4~4.7% in proportion to an increase of solid content without a stabilizing agent and the mixing with a stabilizing agent is similar to the standard mixing. 3. The compressive strength of an early curing age is tendency to increase both the mixing without a stabilizing agent and the mixing with a stabilizing agent. But, After 14days is passed, Compressive strength is decreased in a mixing without a stabilizing agent but increased a mixing with a stabilizing agent.

In this study is investigated the engineering properties of concrete using stabilizing agent of recycling water in order to suggest a practical use of recycling water. According to the results. as stabilizing agent is added. fluidity and air content varies slightly with W/C, but does not make a big difference. Bleeding is reduced by adding stabilizing agent, and so it decreases by about 40% at the adding ratio of 0.15%. When stabilizing agent is not added, compressive strength decreases in comparison with plain concrete, but increases by adding stabilizing agent, so it is largest at adding ratio of 0.30%(W/C 30%) and 0.15%(W/C 40, 50%). Length change by drying shrinkage is larger than plain concrete in the case of no adding of stabilizing agent, but decreases by the use of stabilizing agent. Therefore, it is thought that when stabilizing agent is added to recycling water, quality deterioration of concrete is prevented, moreover, quality of concrete can be improved.

Aims: We aimed to evaluate the efficacy and safety of Daclatasvir (DAV) and Asunaprevir (ASV) in patients with chronic hepatitis C virus (HCV) and chronic renal failure (CRF). Methods: 22 chronic hemodialysis patients with HCV infection at 12 medical centers have prospectively enrolled from Feb, 2016 to Feb, 2017 (NCT02580474). Of those, 9 patients who were followed 12 weeks after treatment ended were included. We evaluated the virological responses at each week 4, 12, 24 and the 12-week sustained virologic response (SVR12). The tolerability and safety of patients were also evaluated. Results: Of these 20 patients, there had no resistance-associated variant of NS5A (NS5A RAVs) and 2 patients showed indeterminate NS5A RAVs. 12 patients (54.5%) completed the 24 weeks treatment of DAV and ASV. 6 patients (27.2%) have continued, but 4 patients discontinued study prior to 12 weeks. Overall, all patients (n=9) achieved SVR12. Virologic response at week 4, 12 and 24 showed 94.4% (17/18), 93.3% (14/15), and 100% (12/12) respectively. DCV and ASV were well tolerated among the majority of patients and discontinuation of the treatment due to adverse events (hypertension, bradycardia, leukemia) was occurred in 3 patients. In two patients with indeterminate NS5A RAVs, one achieved SVR12 but the other showed viral breakthrough and discontinued treatment. Conclusions: In this study, DAV and ASV combination therapy for chronic hemodialysis patients with HCV infection achieved high sustained virological response with few adverse events. Close monitoring of safety and tolerability may be necessary when treating chronic hepatitis C patients with CRF receiving DCV and ASV.

The objective of this research was to investigate the changes in the contents of physicochemical properties including γ-aminobutyric acid (GABA), total dietary fiber (TDF), amylose, protein, and fat content in brown rice through germination for 2 different years. Total phenolic contents and antioxidant activities of DPPH and ABTS radical scavenging capacities were also determined in different solvent extracts. For the physicochemical properties, GABA, TDF, protein, and fat content increased, whereas amylose levels decreased. Specially, GABA and TDF levels showed the greatest variations among cultivars and harvest years. Total phenolic content and antioxidant activity significantly increased. The average total phenolic content at a concentration of 0.5 ㎎/mL in different extract solvents occurred in this order: methanol>ethylacetate>chloroform>hexane extracts. Additionally, 'Keunnun' exhibited the highest GABA levels, highest total phenolic content, and highest antioxidant activity after germination, with increases of approximately 3.7, 2.0, and 1.9 times, respectively, compared to levels before germination. These results suggest that, because of its high physicochemical contents and strong radical scavenging activities, germinated brown rice can be used as beneficial supplement.

Lee, Dong-Soo,Lee, Ji Hye,Park, Jie Yeun,Lee, Seung Jun,Kim, Keun Jung,Kim, Eun Young,Son, Hwa-Young,Sohn, Sea Hwan,Woo, Jae Suk,Kim, Min Kyu The Society ; Maruzen Co. [distributor] 2013 The Journal of veterinary medical science Vol.75 No.2

<P>True hermaphrodites are animals of equivocal sex in which both male and female gonads develop simultaneously in the same individual. The frequency of true hermaphroditism is relatively higher in pigs than in other domestic animals. Two Korean pigs were diagnosed with true hermaphroditism showing ovotestes, epididymides, a penis and uteri. The testicular tissues consisted of Sertoli cells that were devoid of spermatogenic cells and showed proliferation of interstitial cells. However, uteri looked normal and had well-developed endometrial glands. Samples showed the interpretation of 38, XX female karyotype and sex-determining region Y (SRY) gene expression was negative. These findings could be helpful to understand true porcine hermaphroditism for animal research as well as for the industry of Korean domestic animals.</P>

Sea-Won Lee,MD,Tae-Kon Hwang,MD,Sung-Hoo Hong,MD,Ji-Youl Lee,MD,Mi Joo Chung,MD,Song Mi Jeong,MD,Sung Hwan Kim,MD,Jong Hoon Lee,MD,Hong Seok Jang,MD,Sei Chul Yoon,MD 대한방사선종양학회 2014 Radiation Oncology Journal Vol.32 No.3

Purpose: This single institutional study is aimed to observe the outcome of patients who received postoperative radiotherapy after radical prostatectomy. Materials and Methods: A total of 59 men with histologically identified prostate adenocarcinoma who had received postoperative radiation after radical prostatectomy from August 2005 to July 2011 in Seoul St. Mary’s Hospital of the Catholic University of Korea, was included. They received 45–50 Gy to the pelvis and boost on the prostate bed was given up to total dose of 63–72 Gy (median, 64.8 Gy) in conventional fractionation. The proportion of patients given hormonal therapy and the pattern in which it was given were analyzed. Primary endpoint was biochemical relapse-free survival (bRFS) after radiotherapy completion. Secondary endpoint was overall survival (OS). Biochemical relapse was defined as a prostate-specific antigen level above 0.2 ng/mL. Results: After median follow-up of 53 months (range, 0 to 104 months), the 5-year bRFS of all patients was estimated 80.4%. The 5-year OS was estimated 96.6%. Patients who were given androgen deprivation therapy had a 5-year bRFS of 95.1% while the ones who were not given any had that of 40.0% (p < 0.01). However, the statistical significance in survival difference did not persist in multivariate analysis. The 3-year actuarial grade 3 chronic toxicity was 1.7% and no grade 3 acute toxicity was observed. Conclusion: The biochemical and toxicity outcome of post-radical prostatectomy radiotherapy in our institution is favorable and comparable to those of other studies.
