Soybean variety, Hwangkeumkong was planted May 12 in 60×15cm plant density and was transplanted May 26 for some missing hills. Soybean was fertilized with 50kg/10a soybean exclusive compound fertilizer, 10kg/10a fused phosphate, 1.5kg/10a borax, and 1.5kg/10a zinc and as a supplementary was fertilized with potassium chloride in twice. Hilling was performed in three times against lodging damage and damp injury. And pinching was performed June 17. Prop were established for the lodging prevention. Water was applied in five times after early in August. As s result, soybean fields were 667kg/10a.
On–Off Shaping Commands for Asymmetrically Delayed Second-Order Actuators
성윤경,류봉조 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.5
On–off shaping commands are proposed for residual oscillation reduction in undamped flexible systems with asymmetrically delayed second-order actuators, which is a common issue in industrial applications. Asymmetrically delayed second-order actuators could produce large residual oscillations in undamped flexible systems during rest-to-rest operations. Therefore, an exact solution for the on–off shaping commands is developed with a phasor vector approach and step response functions of a second-order system. In addition, a method to obtain robust on–off shaping commands is presented with parameter optimization formulation to compensate for modeling uncertainties under asymmetrically delayed second-order actuators. The control performance of both approaches is analyzed with respect to the command design parameters, residual oscillations, and sensitivity, and it is compared with conventional input shapers. The proposed on–off input shaping commands are numerically evaluated with an undamped single-mode system, and they were experimentally validated with a minibridge crane.
예방적 lamivudine 투여로 성공적인 동종골수이식술을 시행한 HBV 양성 중증 재생불량빈혈 환자 1예

저자들은 만성 B형 감염을 동반한 중증 재생불량빈혈 환자에게 lamivudine을 예방적으로 투여하여 HBV의 재활성 없이 성공적으로 동종골수이식술을 시행하였기에 문헌고찰과 함께 보고하는 바이다. Reactivation of hepatitis B virus (HBV) infection has been known to be a serious complication of immunosuppressive or cytotoxic chemotherapy in HBV carriers or chronic hepatitis B patients. We report here a 25-year-old woman who has severe aplastic anemia and chronic hepatitis B underwent successful allogeneic bone marrow transplantation (BMT) with prophylactic lamivudine treatment and showed no evidence of reactivation of hepatitis B, HBV DNA elevation, or liver dysfunction. This result suggests that prophylactic administration of lamivudine to a BMT recipient of chronic hepatitis B might be a safe and promising measure to prevent fatal liver dysfunction.

Remission is a primary end point of in clinical practice and trials of treatments for rheumatoid arthritis (RA). The 2011 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) remission criteria were developed to provide a consensus definition of remission. This study aimed to assess the concordance between the new remission criteria and the physician’s clinical judgment of remission and also to identify factors that affect the discordance between these two approaches. A total of 3,209 patients with RA were included from the KORean Observational Study Network for Arthritis (KORONA) database. The frequency of remission was evaluated based on each approach. The agreement between the results was estimated by Cohen’s kappa (κ). Patients with remission according to the 2011 ACR/EULAR criteria (i.e. the Boolean criteria) and/or physician judgment (n = 855) were divided into three groups: concordant remission, the Boolean criteria only, and physician judgment only. Multinomial logistic regression analysis was used to identify factors responsible for the assignment of patients with remission to one of the discordant groups rather than the concordant group. The remission rates using the Boolean criteria and physician judgment were 10.5% and 19.9%, respectively. The agreement between two approaches for remission was low (κ = 0.226) and the concordant remission rate was only 5.5% (n = 177). Pain affected classification in both discordant groups, whereas fatigue was associated with remission only by physician clinical judgment. The Boolean criteria were more stringent than clinical judgment. Patient subjective symptoms such as pain and fatigue were associated with discordance between the two approaches.
