Abstract
Coronavirus disease 2019 (COVID-19) first emerged in Wuhan, China in December 2019, and since then the frequency of bacterial and fungal coinfections has been continuously rising. While invasive pulmonary aspergillosis is increasingly being recognized in association with COVID-19, there is limited information with regards to COVID-19 associated mucormycosis. Here, we describe a 50-year-old woman with uncontrolled diabetes who received systemic corticosteroids and remdesevir during her admission for COVID-19. Few days after discharge, the patient was readmitted due to facial swelling and numbness, and a diagnosis of COVID-19 associated rhinosinusitis mucormycosis due to Rhizopus arrhizus (formerly Rhizopus oryzae) was confirmed with sequencing of the internal transcribed spacer (ITS) region of the ribosomal DNA. This report aims to address the importance of short-term follow-up in COVID-19 patients who have received systemic corticosteroids, particularly those with predisposing conditions, as early detection and prompt, aggressive treatment is essential for the management of invasive fungal infections.

Published: June 2021

Abstract
In the research paper, the semi-analytical modelling is done for low drain-induced barrier lowering (DIBL) dual-metal gate all around FET (DM GAAFET). Vacuum and silicon nitride are considered in the act of the gate oxide material near drain region for dual-metal vacuum oxide gate all around FET (DM-VO GAAFET) and dual-metal nitride oxide gate all around FET (DM-NO GAAFET) respectively, in which surface potential, threshold voltage, and DIBL are modelled for both the devices. The proposed models are validated by comparing DM-NO GAAFET with DM-VO GAAFET. DM-NO GAAFET shows the better device performance than DM-VO GAAFET as the threshold voltage increased by 10% and DIBL decreased by 50% in simulated as well as analytical results. The obtained results are having very close agreement with simulated results for both the GAAFETs.

Abstract
Caffeoyl shikimate esterase (CSE) hydrolyzes caffeoyl shikimate into caffeate and shikimate in the phenylpropanoid pathway. In this study, we performed systematic analysis of CSE gene family in poplar and investigated the possible roles of CSEs and CSE-like genes in Populus. We performed a genome-wide analysis of the CSE family, including functional and phylogenetic analyses of CSE and CSE-like genes using the poplar (Populus trichocarpa) genome. Eighteen CSE and CSE-like genes were identified in the Populus genome and five phylogenetic groups were identified from phylogenetic analysis. CSEs in Group Ia, which were proposed as bona fide CSEs, have probably been lost in most monocots except Oryza sativa. Primary functional classification showed that PoptrCSE1 and PoptrCSE2 had putative function in lignin biosynthesis. In addition, PoptrCSE2, along with PoptrCSE12 might also respond to stress with a function in cell wall biosynthesis. Enzymatic assay of Populus tomentosa (Popto) CSE1, -2 and -12 showed that PoptoCSE1 and -2 kept CSE activity. PoptoCSE1 and 2 had similar biochemical properties, tissue expression pattern and subcellular localization. Most of the PoptrCSE-like genes are homologs of AtMAGL (monoacylglycerol lipase) genes in Arabidopsis and may function as MAG lipase in poplar. Our study provides systematic understanding of this novel gene family and suggests the CSE function in monolignol biosynthesis in Populus.

Abstract
1) PurposeThe need for hospice palliative care continues to grow as the number of deaths from cancer increases with increasing interest in and need for the management of end stage cancer patients. We conducted this study to determine differences in quantity and cost of drugs used by end-stage cancer patients who were hospitalized in general wards or hospice wards for 7 days before death.2) MethodsAmong patients who died in the hospice ward or the general ward of a university hospital in a metropolitan city (Seoul) from January 2016 to September 2019, patients aged over 18 years with a hospital stay of 8 days or more were selected. A total of 526 patients were selected, including 290 from hospice wards and 236 from general wards.3) ResultsNumbers of PO, injections, and fluid, but not opioids, used in the hospice ward were significantly lower than those in the general ward. Cost of PO, injections, fluid, and total costs were significantly lower in the hospice ward than in the general ward. In the case of opioids, the cost was higher for the hospice ward. Total costs including all drug costs in the hospice ward were significantly lower than those in the general ward. 4) ConclusionCaring for people with terminal cancer in a hospice can lower costs and increase satisfaction for dying patients. Reducing the proportion of patients caring for terminal cancer in general wards and increasing access to hospice services can address health insurance deficits and exhaustion.

Abstract
A novel, strictly anaerobic, gram-negative, segmented filamentous bacterium (SFB), strain AGMB03513T, was isolated from the faeces of a 5-month-old pig. Comparative analysis of 16S rRNA gene sequences indicated that strain AGMB03513T forms a lineage within the genus Anaerostipes and is most closely related to Anaerostipes butyraticus DSM 22094T (= KCTC 15125T, 95.8%), Anaerostipes hadrus DSM 3319T (= KCTC 15606T, 95.5%), Anaerostipes caccae DSM 14662T (= KCTC 15019T, 94.0%), and Anaerostipes rhamnosivorans DSM 26241T (= KCTC 15316T, 93.4%). Phylogenetic analysis based on the 16S rRNA gene and whole genome sequencing analysis revealed that its closest relatives are members of the family Lachnospiraceae and that the closest related is Anaerostipes butyraticus. Strain AGMB03513T grows at temperatures of between 30 and 45°C within a pH range of 7.0 to 9.0, and in medium containing up to 1.5% NaCl. Cells were found to utilize d-glucose, d-mannitol, d-lactose, d-saccharose, d-maltose, d-xylose, l-arabinose, d-mannose, and d-sorbitol, and acetate was identified as the major end product of metabolism. The DNA G+C content of the strain is 37.0 mol%. Average nucleotide identity (ANI) values obtained in comparisons of strain AGMB03513T with reference strains of species in the genus Anaerostipes were between 71.0% and 75.7%, which are below the ANI criterion for interspecies identity. The major components of cellular fatty acids were C12:0, C16:0, and C18:0. On the basis of phenotypic, phylogenetic, biochemical, chemotaxonomic, and genomic characteristics, we consider it reasonable to assign novel species status to strain AGMB03513T, for which we propose the name Anaerostipes faecalis sp. nov. The type strain AGMB03513T (=KCTC 25020T=NBRC 114896T).

Abstract
Mycelium-based biofoam has the potential to become an alternative to petroleum-polymeric based-foam by utilising fungal mycelium and lignocellulosic material as the matrix and substrate, respectively. The lignocellulosic materials, which were rice husk, sawdust, and sugarcane bagasse, which is crucial for the production of biofoam, were tested as a substrate for Pleurotus ostreatus mycelium growth during the screening procedure. Three growth factors were varied during mycelium-based biofoam production: incubation temperature, spawn loading, and moisture content. In this study, rice husk was the ideal substrate in the production of mycelium biofoam compared to other fungi. The inhibition of P. ostreatus mycelium growth at 30°C incubation temperature was due to decay and contamination. On the other hand, by varying the growth factor of mycelium biofoam on rice husk, the optimum dry density of mycelium-biofoam was observed at 50% (w/w) moisture content (1.07 g/cm3), while the optimum compressive strength was observed at 40% (w/w) spawn loading (1.350 MPa). These results showed that varying the growth factor could influence the mechanical behaviour of the material. The morphology of the biofoam was also observed through a scanning electron microscope (SEM). Short and highly entangled tube-like structures and compact filaments forming a material were seen, responsible for the lightness characteristic of the material. The functional group of the biofoam was also determined using a Fourier transform infrared (FTIR) spectrophotometer. A new band of proteins and lipids was detected at 1633 cm−1 and 3280 cm−1 in the biofoam. It clearly shows that the chemical nature of feeding substrate responsible for the changes of material spectra. Therefore, this study highlighted that the biodegradable mycelium biofoam of P.ostreatus using rice husk as a substrate is a promising alternative to polymeric foam.
Functional Status in Relation to Depression Among Elderly Individuals in Indonesia
Authors: Idaiani Sri , Indrawati Lely 
Published: June 2021

Abstract
Background: Depression among elderly individuals is related to physical illness, functional status, prolonged treatment and other factors. Depression is not effectively treated with medication but can be alleviated by treating the physical illness and improving functional status. Therefore, this study aims to determine the relationship between functional status and depression in elderly individuals in Indonesia.Methods: The data used were obtained from a national survey dataset, namely, the Basic Health Research and Socio-Economic Survey in 2018, which was carried out in 34 provinces and 514 districts or cities. The total number of respondents was 93,829, aged ≥ 60 years. Functional status and depression were assessed using the Barthel index and MINI (Mini International Neuropsychiatric Interview), respectively. Furthermore, data processing was carried out with the Statistical Package for Social Sciences (SPSS) version 26 program and analyzed using the chi-square test and multiple logistic regression with the complex sample method.Results: Elderly individuals with severe dependence were at the greatest risk of becoming depressed compared to those without functional impairment or with independence after considering sociodemographic factors and disease history have 5.730 (95% CI= 4.302-7.632) the adj odds. Furthermore, this figure was higher than that of individuals with total dependence have 4.147 (95% CI=3.231-5.231) the adj odds. The physical illness experienced also played a role in the risk for depression, which was higher among elderly individuals with stroke and a history of injury. The sociodemographic factors involved include low education and economic levels. In contrast, the area of residence and marital status had no statistically significant effect on the relationship between functional disorders and depression.Conclusions: Elderly individuals with decreased functional status are prone to depression. The highest probability for depression was observed among those with severe dependence compared to those with total dependence. Consequently, interventions that involve various sectors, including social and family support, are needed.

Published: June 2021

Abstract
The potential application of biochar in water treatment is attracting interest due to its sustainability and low production cost. In the present study, H3PO4-modified biochar (H-PBC), ethylenediaminetetraacetic acid-modified biochar (E-PBC), and NaOH-modified biochar (O-PBC) were prepared for Ni(II) and Pb(II) adsorption in an aqueous solution. Scanning electron microscopy (SEM), X-ray diffraction analysis, Brunauer–Emmett–Teller analysis, and Fourier transform infrared (FT-IR) spectroscopy were employed to characterize the as-obtained samples, and their capacities for Ni(II) and Pb(II) adsorption were determined. SEM showed that H-PBC retained the hierarchical porous structure of pristine biochar, and projections were observed on its surface. FT-IR showed that H-PBC possessed abundant oxygen-containing and phosphorus-containing functional groups on the surface. H-PBC, E-PBC, and O-PBC all exhibited excellent performance at Ni(II) and Pb(II) adsorption with qmax values of 64.94 mg/g, 47.17 mg/g, and 60.24 mg/g, and 243.90 mg/g, 156.25 mg/g, and 192.31 mg/g, respectively, which were significantly higher than the adsorption capacity (19.80 mg/g and 38.31 mg/g) of pristine biochar. Pseudo-second order models suggested that the adsorption process was controlled by chemical adsorption. Regeneration analysis showed that H-PBC had superior reusability characteristics. H-PBC had a greater adsorption capacity than other adsorbents due to its large specific surface area, and abundant oxygen-containing and phosphorus-containing functional groups. The results obtained in this study suggest that H-PBC is a promising adsorbent for the removal of heavy metals from aqueous solutions.

Abstract
A novel Gram-stain negative, asporogenous, slimy, rod-shaped, non-motile bacterium was isolated from the root samples collected from rice field located in Ilsan, South Korea. Phylogenetic analysis of the 16S rRNA sequence of the bacterium revealed a close proximity to Tianweitania sediminis Z8T (96.5%) followed by genera Mesorhizobium (96.4-95.6%), Aquabacterium (95.9-95.7%), Rhizobium (95.8%) and Ochrobactrum (95.6%). Strain ROOL2T produced white slime on R2A agar plates and grew optimally at 30℃ in the presence of 1-6% (w/v) NaCl and at pH 7.5. The major respiratory quinone was ubiquinone-10 and the major cellular fatty acids were C18 :1ω7c, summed feature 4 (comprising iso-C17:1 I and/or anteiso-C17:1 B) and summed feature 8 (comprising C18:1ω6c and/or C18:1ω7c). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylmethylethanolamine, phosphatidylglycerol, one unidentified aminolipid and two unidentified lipids. The assembled draft genome of strain ROOL2T had 28 contigs with N50 values of 656,326 nt, total length of 4,894,583 bp and a DNA G+C content of 61.5%. The average amino acid identity (AAI) values of strain ROOL2T against the genomes of related members belonging to the same family were below 68%, is below the suggested threshold for genera boundaries. The ANI and dDDH values between the strain ROOL2T and the type strains of phylogenetically related species were 61.8-76.3% and 19.4-21.1%, respectively. Strain ROOL2T only produced carotenoid-type pigment when grown on LB agar but doesn’t produced slime material, in opposite they produced slime materials on R2A and doesn’t produces carotenoid-type pigments. The slime layer protects its inhabitants from environmental dangers such as desiccation and antibiotics. Strain ROOL2T produced indole acetic acid (IAA) in the presence of tryptophan. Bacterial IAA is a crucial phytohormone in plant growth and development. Striking gene clusters for indole-3-glycerol phosphatase and tryptophan synthase were found in the genome of strain ROOL2T. The genotypic and phenotypic characteristics indicated that strain ROOL2T represents a novel genus belonging the family Phyllobacteriaceae, for which the name Oryzicola mucosus gen. nov., sp. nov. is proposed. The type strain is ROOL2T (KCTC 82711T = NBRC 114717T).

Published: June 2021

Abstract
Gesture controlled wheelchair is designed and intended to perform specific job functions combining software interfacing with the hardware along with the embedded electronics, through hand controlled gestures. In this paper, a novel multiple control option-based wheelchair is proposed to cater to the needs of handicapped patients and senior citizens. This work is aimed at designing, integrating, coding, interfacing and testing a fully motorized, gesture controlled wheelchair which involves the physical implementation of the hardware, the software interfacing and testing. This Smart wheelchair is furnished with sensors, interactive cameras controlled by a processor unit that can control the various tasks it is designed to perform. The proposed Smart Wheelchair utilizes micro-electro-mechanical-system (MEMS) accelerometers to recognize various hand gestures performing a specific task. It is an accelerometer-based system which controls a robotic arm wirelessly using a small, low-cost, 3-axis degrees of freedom accelerometer through RF signals. The gestures are also trained by machine learning to identify the training patterns by choosing the appropriate mode selection. The hand gestures are thus based on motion sensor and pattern recognition. Apart from these hand gestures, the smart wheelchair can also be controlled by an android mobile app through a smartphone or by a hand held device that can navigate the smart wheelchair in the forward, backward, right, left directions and also perform a stop operation. The Smart Wheelchair also detects an obstruction present on the way of navigation and is operated in accordance with the command. An interactive camera equipped with a microphone and speaker is meant for communication for the elderly for sending and receiving voice commands remotely. The camera can be accessed through an IoT environment which can be communicated on remote IP addresses on smartphones and personal computers. There are two Arduino Uno Rev3 Controller modules programmed to control the gestures of the gyroscopic accelerometer and other control methods based on a mode selection switch held by the user. The proposed methodology is also realized by Proteus, a simulation tool to check its practical credibility. The proposed circuitry is physically realized as a Smart Wheelchair prototype implemented with the above multi control which could be modified as any physical structure platform having two wheels.

Published: June 2021

Abstract
A compact UWB FSS reflector is presented based on interdigital structure for gain enhancement of an UWB antenna. An equivalent circuit approach is proposed for the analysis of the FSS reflector. The reflector comprises a 6 × 6 array of unit cell dimension 6 mm × 6 mm and which is very compact. The reflector gives a linear phase response over UWB band. A UWB monopole antenna is designed with a half circular disc structure based on microstrip technology. A maximum of 5 dBi gain enhancement is achieved with this compact FSS reflector when placed at a distance below the antenna. The measured results closely follow the simulated ones which proves feasibility of this design.

Abstract
The use of mm Wave or millimeter wave bands for systems based on mobile and wireless communication’s next generation is a promising alternate that has the capability for supporting continuous rates of data over tens of Gigabits per second or Gbps. Although the advantages are clear of using a large available spectrum, there are some challenges which are related to the characteristics of propagation at higher frequency bands which are needed to be dealt. In the existing system, an adaptive transmission that can reduce the probability of outage of secrecy capacity primarily when the mean signal to noise ratio of the eavesdropper is comparatively lower than the legitimate receiver’s mean signal to noise ratio. As more number of devices are connected to the network, security threats are also becoming a real concern. For ensuring the normal operation of smart city, monitoring of abnormal behaviors becomes essential. A smart city requires a guarantee mechanism which is reliable for guaranteeing the QoS. The network’s QoS or quality of service can be affected by various abnormalities in the network like abnormal flow, link fault and DDoS attack etc. which causes packet loss and also interruption of service. Also as more number of IoT devices are connected to the network, security threats are the main issue as more personal information becomes vulnerable.In the proposed system, Design of Resilient or Spatial Correlation is evaluated, this kind of Spatial Correlation enable the physical later to do the iterative search for N number of times until the communication is established without any blockage of objects. To reduce the disconnection of data transfer due to line of sight issues, an adaptive Resilient Correlation scheme is newly proposed here.
