Antibacterial low‐density polyethylene (LDPE)‐ and poly (lactide)/poly (butylene adipate‐co‐terephthalate) (PLA/PBAT)‐based films incorporated with elemental sulfur (ES) nanoparticles (SNPs) were prepared using a blow extrusion method for food packaging applications. Flexible free‐standing manufactured an industrial processing without any modification. The characterized ultraviolet (UV)–visible spectroscopy, field emission scanning electron microscope (FESEM), X‐ray diffraction (XRD),...

The unit cell structures of the consist a combination an ordinary Jerusalem cross and its complementary counterpart that resonates THz regime. columnar repetition resonator enables spectral responses incident waves with mutually orthogonal linear polarizations. operating principles metamaterial interaction between juxtaposed crosses are explained using equivalent circuit method confirmed full-wave...
A three octave ultra‐wideband 3‐port circulator is proposed and implemented using 110 nm CMOS technology. The operates across the frequency range from 0.5 to 4 GHz with supply voltage of 3 − V. measured insertion loss 1.3 4.9 dB, return better than 12 dB isolation more dB.
This retrospective cross-sectional study aims to investigate the prevalence and seriousness of drug-induced nephrotoxicity identify clinical predictors intensifying nephrotoxicity. Adverse drug events (ADEs) reported Korean Event Reporting System Database (KAERS DB) from January 2012 December 2021 were investigated. The association between etiologic was estimated in reporting odds ratio (ROR) based on disproportionality analysis. Logistic regression utilized recognize associated with serious...
Abstract Strong and narrowband terahertz (THz) radiation is obtained from a GaAs‐based pseudomorphic high‐electron‐mobility transistor (pHEMT). The properties with respect to the bias conditions operating temperature are extensively characterized. maximum emission power measured be 63 278 μW at room 77 K, respectively. By using THz pHEMT, metal object hidden in cloth was successfully imaged.
The purpose of the present study was to evaluate bioequivalence two torasemide tablets, Torem tablet (Roche Korea Co., Ltd., Korea, reference drug) and Boryung Torsemide (Boryung Pharmaceutical test drug), according guidelines Food Drug Administration (KFDA). After adding an internal standard (furosemide) human serum, serum samples were extracted using 5 mL ethyl acetate. Compounds analyzed by reverse-phase HPLC method with UV detection. This showed linear response over concentration range...
In recent years, the demand for real-time multi-media service in WLAN environment rapidly increases due to Wi-Fi smart phone user growth. order transmit multimedia many users, broadcast transmission is more efficient than unicast transmission. However, without retransmissions leads higher loss rate real wireless environments. this paper, we propose a phone-based reliable system with packet-level forward error correction scheme using Reed-Solomon code. According our experimental results,...
This study aims to investigate the prevalence and seriousness of drug-induced arrhythmia identify predictors associated with arrhythmia. Drug-induced cases reported Korean Adverse Event Reporting System Database (KAERS DB) from January 2012 December 2021 were investigated. A disproportionality test was performed detect association etiologic medication classes types, along patient demographic information, Logistic regression that increase risk serious The most common agent for sevoflurane,...
Meloxicam-loaded microspheres were prepared with poly(D,L-lactic acid)(PLA) by a solvent-emulsion evaporation method. The morphology, particle size, drug loading capacity, entrapment efficiency (EE) and release patterns of investigated in vitro. Various batches micro spheres different size content obtained changing the ratio meloxicam to molecular weight, PLA concentration dispersed phase stirring rate. Meloxicam crystals on microsphere surface, which released rapidly could act as dose,...
We designed dynamic projection mapping system for augmented character in performing art. Motion data collection coordinate space should be acquired to track shape and movement of a project on the real time. Also, interactive three-dimensional contents need identical precisely character.
In the wireless sensor network, there are cluster based routing protocols for network monitoring like LEACH. earlier works, data aggregation periods of these same, although each can have different environments or situations time-varying. Thus, it occurred to inefficiently consume energy in non-interested areas. addition, is also inefficient interested areas that require frequent measurements because next measurement time fixed regardless current environment. Therefore, this paper, we suggest...
