In this paper, we study the long-time dynamical behavior for the extensible suspension bridge equations with past history. We prove the existence of the global attractors by using the contraction function method. Furthermore, the regularity of global attractor is achieved.

본 연구에서는 종횡비가 낮은 직사각형 밀폐용기 내에 Rayleigh수가 충분히 커서 흐름의 운동력이 용기 양단에 존재하는 경우에 PartⅠ에서 개발된 해석적인 모델 을 근거한 scaling analysis를 통해 그 내부 흐름 형태를 정성적으로 예측, 기존의 결 과와 비교, 검토하였다. 해석결과, Prandtl수에 따라 여러가지 내부 흐름 형태가 존 재할 수 있음이 밝혀졌으며 용기 내 뚜렷한 경계층 흐름이 존재하기 위한 필요조건도 아울러 얻어졌다.

For solving symmetric systems of linear equations, it is shown that a new Krylov subspace method can be obtained. The new approach is one of the projection methods, and we call it the projection method for convenience in this paper. The projection method maintains the residual vector like simpler GMRES, symmetric QMR, SYMMLQ, and MINRES. By studying the quasiminimal residual method, we show that an extended projection method and the scaled symmetric QMR method are equivalent.

We investigate strong convergence of Halpern's iteration for a countable family of strongly relatively nonexpansive mappings in the framework of uniformly convex and uniformly smooth Banach spaces. Our results extend those announced by many authors.

ThingsBoard에서 사용되는 엑세스 토큰 인증 방식에 블록체인 메커니즘을 적용하여 디바이스의 무결성을 강화한다. 인증에 사용되는 데이터는 보호되어야 하고, 빠르게 제공되어야하기 때문에 제안 인증 방식에 퍼미션드 블록체인을 사용한다. 본 논문은 실험을 통해 블록체인 기반의 제안 인증 방식이 디바이스의 무결성을 강화하면서도 큰 성능저하를 발생시키지 않는 것을 검증한다.

인간의 보행에는 다양한 분야에서 유용하게 사용할 수 있는 정보를 가지고 있어 의료분야와 수사기관에서 사용되고 있다. 보행 데이터로부터 유용한 정보를 얻어내기 위해 선행되어야 하는 작업은 보행주기를 판별하는 것이다. 본 연구에서는 보행주기 판별을 위하여 발 뒷굽 닿기와 발가락 떼기 행동을 가속도 값과 각속도 값을 사용하여 알아내고, 정확도를 분석하는 알고리즘에 대해 논한다.

This study was carried out to compare the bioavailability of $Ceclex^{(R)}$ SR TAB (test drug, cefaclor 375 mg/Tablet) with that of Ceclor $MR^{(R)}$ SR IAB (reference drug) and to estimate the pharmacokinetic parameters of cefaclor in healthy Korean volunteers. The bioavailability was examined on 24 healthy volunteers who received a single dose (375 mg) of each drug in the fasting state in a randomized balanced 2-way crossover design. After dosing, blood samples were collected for a period of 7 hours. Plasma concentrations of cefaclor were determined using HPLC with UV detection. The pharmacokinetic parameters $(AUC_{0-7h},\;C_{max},\;T_{max},\;AUC_{inf},\;K_e,\;t_{1/2},\;V_d/F,\;and\;CL/F)$ were calculated with non-compartmental pharmacokinetic analysis. The ANOVA test was utilized for the statistical analysis of the $T_{max}$, log-transformed $AUC_{0-7h$}$, log-transformed $C_{max},\;t_{1/2},\;V_d/F$, and $CL/F$. The ratios of geometric means of $AUC_{0-7h}\;and\;C_{max}$ between test drug End reference drug were $95.67\%\;(8.55\;vs\;8.18{\mu}g{\cdot}hr/ml)\;and\;103.86\%\;(2.85\;vs\;2.96{\mu}g/ml)$, respectively. The $T_{max}$ of test drug and reference drug was $2.56\pm0.15\;and\;2.23\pm0.13\;hrs,\;respectively.\;The\;90\%$ confidence intervals of mean difference of logarithmic transformed $AUC_{0-7h}\;and\;C_{max}$ were log0.90-log1.04 and log0.91-log1.13, respectively. It shows that the bioavailability of test drug is equivalent with that of reference drug.
