Methodology for Real-Time Evaluation of Geographic Health Care Resource Allocation: Iwate Prefectural Hospitals

The effective utilization and assessment of medical resources have become a common concern for scholars in various countries due to the impact of the COVID-19 pandemic. This study deals with a method to monitor medical resource allocation in real-time and verify the effectiveness of the proposed method with actual data. In this work, we selected Iwate Prefecture in northeastern Japan based on the geographical characteristics and social environment. By collecting data from the Japanese Ministry of Land, Infrastructure, Transport, and Tourism and Welfare (MLIT), we clustered population centers in Iwate Prefecture, and found the clustering centers in densely populated areas from the k-means algorithm. Subsequently, to compare the distribution of county-level medical resources across different secondary care areas, we selected the indicators of Iwate Prefectural Hospitals from the Hospital Intelligence Agency. We classified 19 prefectural hospitals in Iwate Prefecture into four different clusters using the spectral clustering algorithm. The clustering results revealed that all hospitals close to the " clustering centers in densely populated areas" were Iwate prefectural disaster stronghold hospitals. Moreover, we found that these hospitals performed well in operational indicators. Only the Ninohe prefectural hospital in the Ninohe medical area was found not located in a population center. However, it still performs well in terms of business indicators since the Ninohe medical area has a high proportion of public hospitals and the Ninohe prefectural hospital plays an important role. Hence, the government should fully consider geographical characteristics when considering hospital restructuring. We used a real data set to demonstrate the validity of the proposed technique, providing a theoretical basis for the government's healthcare policy.
Trophic interactions and metal transfer in marine ecosystems driven by the Peruvian scallop
 Argopecten purpuratus
 aquaculture

This study investigates the trophic interactions and As and Cd transfer along seven marine ecosystems in Peru. Five of these ecosystems are driven by aquaculture of highest trophic magnification factors (TMFs) were 1.46 and 1.07 for As and Cd, respectively, and were both found at the location in front of the Illescas Reserve Zone (northern Peru). Metal biomagnification and non-biomagnification effects were found in the Peruvian marine food webs, but A. purpuratus always fitted the trophic metal magnification or bio-dilution regression model as intermediate consumer and/or prey. The TMFs and linear metal relationships implied that As contamination is a serious concern in marine ecosystems in Peru. The aim of this study is to understand the structure of the different marine ecosystems in Peruvian coastal waters. Trophic interactions and metal transfer (i.e., possible biomagnification effects) were determined along the food webs. Because the presence of the Peruvian scallop A. purpuratus aquaculture was relevant in most locations (i.e., SB, IRZ, and Paracas Bay), the first insights in these ecosystems could also be used for appropriate management of this important economic activity in Peru, as well as to understand the role of A. purpuratus as a vector of metals in seafood for human consumption. This study revealed a trend of increasing δ 15 N and δ 13 C from food sources to top consumers (i.e., snails, crabs, octopus, shrimps), by passing through the scallop A. purpuratus . This points at A. purpuratus ' crucial role as intermediate consumer and main food item for predators in the studied marine food webs. Based on SIAR-mixed models, the most voracious consumers of A. purpuratus were: Cymatium sp. > H. chilensis > O. mimus > T. chocolata > R. setosum > B. ventricosa , thus we suggest to prioritize these species in any major fishing (removal) effort to reduce the operational culture costs. The invasive C. filiformis seems to be part of the benthic food webs; this species is playing an important role in energy transfer as main food source for herbivorous consumers (e.g., sea urchins). Trophic regression lines also showed that A. purpuratus is a key prey species for the most important predators, as well as the main source for metal transfer to higher trophic levels. Even in food webs where a non-biomagnification (or bio-dilution) effect was observed, A. purpuratus played a key role in the metal transfer. Seston is the major contributor to A. purpuratus ' diet, followed by sediments and marine and brackish water POM, leaving the freshwater (river) POM input as the least important contributor. TMFs led to conclude that As is an actual concern in Peruvian marine ecosystems.
Recent progress on precious metal single atom materials for water splitting catalysis

Electrochemical water splitting for hydrogen production has sparked intensive interests because it provides a new approach for sustainable energy resources and the avoidance of environmental problems. The precious metal‐based single atomic catalysts (PMSACs) have been widely employed in water splitting catalysis by virtue of their maximum atom utilization and unique electronic structure, which can reduce metal amounts and remain high catalytic performance simultaneously. In this review, we will summarize recent research efforts toward developing SACs based on precious metals with excellent performance for electrochemical water splitting catalysis. First, the synthesis strategies for PMSACs will be classified and introduced including high‐temperature pyrolysis, electrochemical method, photochemical reduction, wet chemistry method, etc. Then, a short description of characterization techniques for SACs will be given, which mainly involves the aberration‐corrected scanning‐transmission electron microscopy (AC‐STEM) and X‐ray absorption spectroscopy (XAS). In particular, the relationship between the electronic structure of the precious metal atomic sites and performance for water splitting will be discussed according to the theoretical and experimental results. Finally, a brief perspective will be provided to highlight the challenges and opportunities for the development of novel PMSACs suitable for electrochemical water splitting applications.

SITool (v1.0) – a new evaluation tool for large-scale sea ice simulations: application to CMIP6 OMIP

Abstract. The Sea Ice Evaluation Tool (SITool) described in this paper is a performance metrics and diagnostics tool developed to evaluate the skill of bi-polar model reconstructions of sea ice concentration, extent, edge location, drift, thickness, and snow depth. It is a Python-based software and consists of well-documented functions used to derive various sea ice metrics and diagnostics. Here, the SITool version 1.0 (v1.0) is introduced and documented, and is then used to evaluate the performance of global sea ice reconstructions from nine models that provided sea ice output under the experimental protocols of the Coupled Model Intercomparison Project 6 (CMIP6) Ocean Model Intercomparison Project with two different atmospheric forcing datasets: the Coordinated Ocean-ice Reference Experiments version 2 (CORE-II) and the updated Japanese 55-year atmospheric reanalysis (JRA55-do). Two sets of observational references for sea ice concentration, thickness, snow depth, and ice drift are systematically used to reflect the impact of observational uncertainty on model performance. Based on available model outputs and observational references, the ice concentration, extent, and edge location during 1980–2007, as well as the ice thickness, snow depth, and ice drift during 2003–2007 are evaluated. It is found that (1) in general, model biases are larger than observational uncertainties and model performances are primarily consistent compared to different observational references, (2) By changing the atmospheric forcing from CORE-II to JRA55-do reanalysis data, the overall performance (mean state, interannual variability and trend) of the simulated sea ice areal properties in both hemispheres, as well as the mean ice thickness simulation in the Antarctic, the mean snow depth and ice drift simulations in both hemispheres are improved, (3) the simulated sea ice areal properties are also improved in the model with increased spatial resolution, (4) for the cross-metric analysis, there is no link between the performance in one variable and the performance in another. The SITool is an open-access version-controlled software that can run on a wide range of CMIP6 compliant sea ice outputs. The current version of SITool (v1.0) is primarily developed to evaluate atmosphere-forced simulations and it could be eventually extended to fully coupled models.
Knowledge management in project management: mapping bibliographic convergence

ABSTRACT The present study sought to map the bibliographic convergence of Knowledge Management (KM) and Project Management (PM). To achieve this goal, we adopted bibliometric techniques, supported by exploratory factor analysis (EFA). The bibliographic coupling showed that the emerging KM literature deals with KM and results in PM, KM and project-oriented organisations, KM and project success, projects as a knowledge source, KM in interorganisational projects, and knowledge transfer in projects. Moreover, we determined that the intellectual structure of the area, KM fundamentals, KM and learning in project-based organisations, KM in organisations and projects, and KM and social mechanisms were also notable themes. Additionally, the EFA detected a relationship between the emerging themes and articles representing the intellectual structure. Furthermore, our results provide insights practitioners can use to recognise emerging issues the organisation is experiencing in the literature.
Bacterial Cellulose Nanocrystals (BCNC) Preparation and Characterization from Three Bacterial Cellulose Sources and Development of Functionalized BCNCs as Nucleic Acid Delivery Systems

Bacterial cellulose (BC) is an excellent renewable resource of high-purity cellulose that can be used as original fiber forms or isolated nanocrystalline forms, known as bacterial cellulose nanocrystals (BCNCs), which have gained more attention in the development of highly biocompatible biomaterials. In this work, BCNC production was studied with regard to the influences of the varying BC sources (BC pellicles produced by three different BC-producing bacterial strains of Komagataeibacter xylinus) and acid hydrolysis conditions (hydrochloric acid, sulfuric acid, and a mixture of both acids) on the production yield, morphology, and physicochemical properties of the resulting BCNC. BCNC production with these variable factors provided the distinctive characteristics of rodlike nanocrystals, which can be useful for various applications. For demonstration of the biomedical application as nucleic acid delivery systems, cationic BCNCs were developed by simple cationic surface modification by the physical adsorpti.
In Vitro Study of Antioxidant Activity of Serum and Plasma Samples As Well As Glutathione Exposed to Various Exogenous Stress Factors

The imbalance between the production of Reactive Oxygen Species (ROS) and their sequestration promotes the formation of so-called oxidative stress conditions which are considered crucial in the aging process and development of many human diseases. Glutathione plays an essential role in the antioxidative barricade against ROS. Its role in the detoxification process of xenobiotics and carcinogen is also known. However, there are no comparative studies on the antioxidant properties of both biological samples and glutathione as well as the change in these properties as a result of exposure to various stress factors. This paper fills this gap comparing the antioxidant activity of serum and plasma samples of the known glutathione content with the activity of glutathione itself assessed by the different methods. In addition, it reveals a significant role of environmental xenobiotics in oxidative stress and differentiates the stress induced by different groups of drugs, among which the greatest one has been demonstrated for antiarrhythmic drugs and cytostatics. More importantly, it proves that human plasma is more resistant to stress factors and N-acetylcysteine clearly promotes the extension of antioxidant properties of both the plasma and serum samples. The latter conclusion is consistent with the implied preventive and/or supportive action of this drug against SARS-CoV-2.
Modelling the Relationship between Sludge Filtration Resistance and Capillary Suction Time

This study modeled the relationship between Sludge Filtration Resistance (SFR) and Capillary Suction Time (CST) using the data generated from different concentrations of CaCl2 for SFR and CST empirically using the Equation proposed by Christensen et al. (1993). The main purpose of conducting CST and SRF tests at wastewater treatment plants is to save operating costs by evaluating the optimal dose of the sludge conditioner, known as the dose of coagulant that yields the minimal capillary suction time or resistance to filtration. In order to establish a relationship between the SFR with CST, there is a relatively good correlation between CST and SFR. The results showed that the values of CST decreased with increasing CaCl2 concentration, and a good dewaterability could be obtained at the CaCl2 dosage of 18 g with the corresponding CST of 5.52 s for 20 mm internal cylinder and 30.84 s for 14.5 mm internal cylinder. The results of SFR tests shown decreased with an increase in CaCl2 dosage. The optimal CaCl2 dosage was 18 g and the corresponding SFR was 2.65 × 108 N·s/m5. The results of this study for CST recommend larger diameter cylinder to be used to test heavy sludge because the larger cylinder significantly reduces the variability and the time taken to conduct the CST tests.
“Alexa, let me ask you something different” Children's adaptive information search with voice assistants

In this study, we investigated how children interact with voice assistants, particularly focusing on what kinds of questions they ask and how they react to the responses obtained. We recorded 3-to 10-year-old children's ( N = 43) spontaneous interactions with Amazon Alexa, and analyzed the questions they asked, as well as how they adjusted their information search based on the responses received. Our results confirm previous work in showing that children's questions are mostly information-seeking, yet the type of questions children ask also depends on their age and familiarity with voice assistants. For example, children who are younger and less familiar with voice assistants are more likely to ask questions about themselves and their environment (e.g., “ What is my sister's name? ” ). We also show for the first time that, even though all children are sensitive to the relevance and accuracy of voice assistants' responses to a certain extent, older children are more likely to change the topic and type of the questions asked upon receiving irrelevant or uninformative responses. This study shows that, with age and familiarity, children become more sensitive to the behavior, informativeness, and constraints of artificial agents, growing into adaptive and sophisticated technology users.
Broadband crossed dipole circularly polarized antenna with parasitic round‐metal pillars

A broad crossed dipole circularly polarized antenna (CPA) with modified and parasitic elements is presented. The crossed dipole CPA is consisted of a pair of vacant‐quarter printed rings as continuous phase feeding structure, four L‐shaped strips as radiated patch, four grounded round‐metal pillars as parasitic element and a circular ground as a reflector. Note that two deformed trapezoid‐microstrip lines as impedance matching element are used to feed the crossed dipole CPA, which is different from the traditional rectangular‐microstrip lines. Moreover, the rotated L‐shaped strips as radiated patch are used to realize CP radiation, but four rotated grounded round metal pillars as the only parasitic element are arranged at the edge of the L‐shaped strips to improve the CP bandwidth. Through making use of these elements, multiple CP resonant modes could be together stimulated, which leads to an increase in the CP bandwidth. The antenna prototype is fabricated and tested to verify the rationality of the design. Finally, the designed crossed dipole CPA features a broad 3‐dB axial ratio bandwidth of 78% (1.25‐2.85, 2.05 GHz), and a wide −10‐dB impedance bandwidth of 107.4% (0.94‐3.12, 2.03 GHz), which could include the WiBro (2.3‐2.39 GHz) and GPS (L1 1.575 GHz) band. Thus, the presented crossed dipole CPA would be a very promising candidate in the wireless communication systems.
Application of Statistical Monitoring Using Autocorrelated Data and With the Influence of Multicollinearity in a Steel Process

The purpose of this article is to demonstrate a practical application of control charts in an industrial process that has data auto-correlated with each other. Although the control charts created by Walter A. Shewhart are very effective in monitoring processes, there are very important statistical assumptions for Shewhart's control charts to be applied correctly. Choosing the correct Control Chart is essential for managers to be able to make coherent decisions within companies. With this study, it was possible to demonstrate that the original data collected in the process, which at first appeared to have many special causes of variation, was actually a stable process (no anomalies present). However, this finding required the use of autoregressive models, multivariate statistics, autocorrelation and normality tests, multicollinearity analysis and the use of the EWMA control chart. It was concluded that it is of fundamental importance to choose the appropriate control chart for monitoring industrial processes, to ensure that changes in processes do not incorporate non-existent variations and do not cause an increase in the number of defective products.
Bradyrhizobium inoculation has a greater effect on soybean growth, production and yield quality in organic than conventional farming systems

Abstract Globally, organic farming and bradyrhizobia inoculation are gaining popularity as agronomically and environmentally sound soil management strategies with great potential to alleviate declining soil fertility, maintain environmental quality and enhance soybean production. However, the role of bradyrhizobia in organic farming system is poorly understood. Field experiment was conducted to evaluate the effects of bradyrhizobia inoculation and organic farming on growth parameters and yield quality of soybean varieties: SC squire, SB19 and Gazelle. The experimental treatments included native bradyrhizobia, commercial Bradyrhizobium japonicum, mixture of native + commercial bradyrhizobia and uninoculated control. The experimental design was a split-split plot, with three replications. The results demonstrated significant improvement in soybean nodule dry weight (NDW), shoot dry weight (SDW) and seed dry weight (SEDW) following bradyrhizobia inoculation. Remarkably, organic farming significantly out-performed conventional systems in nodulation, SDW and SEDW. Moreover, seed nutrient content differed depending on farming system; where nitrogen, phosphorus, potassium and organic carbon were higher in organic farming. Soybean varieties differed significantly on SDW, NDW and SEDW; where SC squire performed better than SB19 and Gazelle. The results demonstrate the importance of organic farming and bradyrhizobia inoculation in enhancing soil fertility, yield production and quality, a key step towards sustainable food production.
Green synthesis of silver nanoparticles using Cordia dichotoma fruit extract and its enhanced antibacterial, anti-biofilm and photo catalytic activity

The present study describes the antibacterial, anti-biofilm and photo catalytic activity of silver nanoparticles synthesized using Cordia dichotoma fruits (Cd-AgNPs) for the first time. The phyto-synthesized Cd-AgNPs were characterized by UV-Visible spectroscopy, Field emission-scanning electron microscopy (FE-SEM), Transmission electron microscopy (TEM), Energy dispersive x-ray spectrometer (EDX), Fourier transform infrared spectroscopy (FT-IR), and x-ray diffraction (XRD). FE-SEM and TEM observation showed that the average size of 2–60 nm with spherical shape of Cd-AgNPs and the presence of phyto-compounds which are responsible for capping and reduction were studied by FT-IR. XRD studies revealed the face-centered cubic structure of Cd-AgNPs. The synthesized Cd-AgNPs showed significant antibacterial activity against Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli, assayed using agar well diffusion method. Phyto-synthesized Cd-AgNPs exhibited more than 90% inhibition of biofilm activity formed by S. aureus and E. coli. Furthermore, photocatalytic degradation of crystal violet (CV) under UV light irradiation using Cd-AgNPs was performed. Synthesized Cd-AgNPs exhibited ∼85% degradation activity for CV. Collectively, our findings suggest that C.dichotoma is a green source for the eco-friendly synthesis of Cd-AgNPs, which further can be used as a novel biocidal agent against bacterial pathogens and a potent photo catalytic agent.
Insights into Transcriptional Regulation by Individual H3K4 Methylation Marks in S. Cerevisiae

Set1 is a lysine methyltransferase in S. cerevisiae that catalyzes the mono, di and tri methylation of the fourth lysine on the amino terminal tail of histone H3 (H3K4). Set1-like methyltransferases are evolutionarily conserved, and research has linked their function to developmental gene regulation and several cancers in higher eukaryotes. Set1 is a member of the multiprotein COMPASS complex in S. cerevisiae. The H3K4 methylation activity of COMPASS regulates gene expression and chromosome segregation in vivo. The three distinct methyl marks on histone H3K4 act in discrete ways to regulate transcription. Trimethylation of H3K4 is usually associated with active transcription whereas dimethylation of H3K4 is associated with gene repression. In this study, amino acid substitution mutants of SET1 that encode partial function Set1 proteins capable of H3K4me1, H3K4me1 and H3K4me2, or H3K4me1and H3K4me3 were analyzed to learn more about the roles of individual H3K4 methyl marks in transcription. The findings reveal a previously unappreciated role for H3K4me1 in activation of transcription of the HIS3 gene in S. cerevisiae cultures grown under histidine-starvation conditions. Surprisingly, induction of the HIS3 gene in cultures grown under histidine starvation is not accompanied by significant changes in the profiles of H3K4-methylated nucleosomes at the HIS3 gene in SET1 wild-type strains and set1 partial-function mutants. The data show that H3K4me1 supports induction of HIS3 mRNA to wild-type levels under histidine-starvation conditions and that higher-order H3K4 methylation (H3K4me2 and H3K4me3) is not required.
