B-ISDN using ATM should provide QoS of various service and also fair control for each source. In this paper, we suggested the Virtual-Time-based Round Robin(VTRR), fair scheduling algorithm guaranteeing demanded QoS. We searched the characteristic and required points possessing proper fair scheduling algorithm in high speed network. And we analyzed the performance character and simulation. The result is that VTRR is much simpler in algorithm and is better than WFQ or GPS in performance.

It is very important item the prediction of wave height distribution in harbor before the construction. If the harbor calmness is not good after the construction. it will be considered again. A numerical model based on the mild slope equation is occasionally used to calculate the wave height distribution in the harbor. But this model is usually described for regular waves. We attempted the prediction method an irregular wave field by energy superposition for regular waves with different wave direction and frequencies. Also. this applicability study was investigated on the onsan harbor

In this research, we made a one and two-dimensional analysis of numerical data collected from the bend curvature of a bended river section. According to the result from the numerical analysis, the inflow & output angle caused a water level deviation which increased with an increase of the flood discharge. From the water level deviation of our two- dimensional numerical model, we obtained the maximum slope of 6,67% when the inflow and output angle was 105 degrees and the flood discharge was 500 CMS. As for the right side, the differences with the one-dimensional numerical model were reduced when the angle was more than 90˚. As for the left side the differences were reduced when the angle was more than 105˚. For a river with more than 90 degrees bend curvature, a hydraulic experiment would be more appropriate than a numerical analysis.

Lavandula vera is indispensable member of the herb family, used for perfumes and potpourri. Androgens have profound effects on the physiology of the sebaceous gland. Sebum is secreted due to the effect of androgen, which starts to be secreted at puberty. Using the human sebocyte cell line SZ95, the author investigated the inhibitory effect of Lavandula vera on the lipid production. Light microscopic finding were examined numerous cytoplasmic lipid droplets SZ95 cells by Oil red staining and lipid droplets were increased markedly by testosterone. On the other hand, combined treatment with Lavandula vera and testosterone resulted in a lower lipid droplets than with testosterone alone in a dose-dependent manner. These findings indicate that Lavandula vera acts antagonistically to testosterone and inhibits the lipid synthesis of SZ95 cells at the cellular level.
Air-ring microstructure arrays for enhanced light extraction from a face-up light-emitting diode.
Kim, Hyun Kyu,Park, Young Jae,Kang, Ji Hye,Han, Nam,Han, Min,Ryu, Beo Deul,Ko, Kang Bok,Yang, Jong Han,Kim, Young Taek,Chandramohan, S,Jeong, Hyun,Jeong, Mun Seok,Hong, Chang-Hee Optical Society of America 2013 Optics letters Vol.38 No.9
<P>In this Letter, a light-emitting diode (LED) with prism-shaped-air-ring microstructures (PSAMs) formed on flat sapphire substrate is demonstrated as an alternative design to face-up LEDs on patterned sapphire substrate (PSS) for enhanced light extraction efficiency. In this LED design, the emitted photons can be deflected to the top of the chip for its effective extraction, contrary to the PSS-LED wherein photons are guided to sapphire and get absorbed by packaging materials. The PSAM-LED showed an enhancement in the radiometric power as high as 10% with a low far-field angle of 129 over that of a PSS-LED under an injection current of 20 mA.</P>

Purpose: The midline catheter (MC) is a peripheral venous access device with the catheter tip located in the axilla and available for mid-term intravenous (IV) therapy. This study evaluated the efficacy and clinical outcomes associated with the placement of MCs with an integrated wire-accelerated Seldinger technique for IV access. Materials and Methods: A retrospective review was conducted at a single center in South Korea between March 2020 and July 2020. Consecutive patients in whom MC insertions were performed by vascular surgeons were enrolled. The outcomes included catheter indwelling time and incidence of catheter-related adverse events. Results: Ninety-five patients (117 catheters) were included in the study. The total indwelling time was 1,964 days, with a median of 16.7 days (range, 0-76). The complication-free catheter rates at 5 and 28 days were 92.9% and 65.5%, respectively. Overall, 32 (27.4%) catheters were removed due to complications; however, major complications, such as symptomatic deep venous thrombosis and catheterinduced bloodstream infections, were confirmed in only 3 (2.6%) catheters. A common reason for premature catheter removal is inadvertent removal owing to patient inattention. A high body mass index and female sex were identified as risk factors for short indwelling times and complicated premature catheter removal. Conclusion: MC insertion is a simple and operator-friendly procedure with a low rate of major complication. It enables mid-term IV treatment through a single procedure if there are no specific complications, thereby improving quality of life of patients during hospital stay.
