Adherence to the Japanese Food Guide: The Association between Three Scoring Systems and Cardiometabolic Risks in Japanese Adolescents

The Japanese Food Guide Spinning Top (JFGST) indicates optimal intake of five food groups (grain, fish and meat, vegetables, milk, and fruits) and sugar and confectionaries. We aimed to investigate whether adherence to the JFGST in 8th grade junior high school students (n = 3162) was associated with cardiometabolic risks and how different scorings of the JFGST influenced the associations. Metabolic risks were assessed from anthropometrics, blood pressure measurements, and blood glucose and lipid profile measurements. Three types of scoring adherent to the JFGST were analyzed (10 points were given for each item with optimal intake; range: 0–60): the original scoring (ORG scoring); first modified scoring, which had no upper limits for vegetables and fruits (MOD1 scoring); and MOD2 scoring without upper limits for five dishes (MOD2 scoring). The MOD2 scoring was positively associated with dietary fiber, potassium, calcium, and vitamins. All types of scorings were associated with low glucose levels (p ≤ 0.001); the MOD2 scoring was associated with low systolic blood pressure (p = 0.001) and low cardiometabolic risk (p = 0.003). Our findings suggest that Japanese adolescents adherent to the JFGST had low cardiometabolic risks and should not fall below lower limits for intake of the abovementioned five food groups.
Social Media Use Among Library and Information Science Students: A Case Study

The purpose of this study is to identify the prevailing conditions of social media use among undergraduate students of Library and Information Science in a Nigerian University. Simple random sampling technique was used to select a sample of 180 full-time undergraduate students purposely. Descriptive statistics was used to analyze data collected through the administration of questionnaire. Research findings showed that a great number of students of Library and Information Science are addicted to social media for wrong academic purposes. The levels of addiction varied according to four Likert scale type. The highly addiction was among student using WhatApp (40.82%) and not addicted among students using BB chat (13.12%). The demographic indicators provided the obvious results of singles (77.78%) possessing prevalence tendency of addiction, and surprisingly those between the ages of 27-30 (40%) were most addicted. The paper recommends awareness programmes that are tailored to reveal the ills of social media addiction and pave ways to balance use of social media platforms that benefit academic activities among students.
Fabrication and Characterization of Nanocomposite Hydrogel Based on Alginate/Nano-Hydroxyapatite Loaded with Linum usitatissimum Extract as a Bone Tissue Engineering Scaffold

In the current paper, we fabricated, characterized, and applied nanocomposite hydrogel based on alginate (Alg) and nano-hydroxyapatite (nHA) loaded with phenolic purified extracts from the aerial part of Linum usitatissimum (LOH) as the bone tissue engineering scaffold. nHA was synthesized based on the wet chemical technique/precipitation reaction and incorporated into Alg hydrogel as the filler via physical cross-linking. The characterizations (SEM, DLS, and Zeta potential) revealed that the synthesized nHA possess a plate-like shape with nanometric dimensions. The fabricated nanocomposite has a porous architecture with interconnected pores. The average pore size was in the range of 100–200 µm and the porosity range of 80–90%. The LOH release measurement showed that about 90% of the loaded drug was released within 12 h followed by a sustained release over 48 h. The in vitro assessments showed that the nanocomposite possesses significant antioxidant activity promoting bone regeneration. The hemolysis induction measurement showed that the nanocomposites were hemocompatible with negligible hemolysis induction. The cell viability/proliferation confirmed the biocompatibility of the nanocomposites, which induced proliferative effects in a dose-dependent manner. This study revealed the fabricated nanocomposites are bioactive and osteoactive applicable for bone tissue engineering applications.
Variáveis institucionais explicativas do desempenho de estudantes de Ciências Contábeis e Administração

O objetivo deste estudo foi analisar a associação entre variáveis institucionais e o desempenho de estudantes de ciências contábeis e administração. Foram utilizados os microdados do Enade 2018, obtendo-se 152.491 observações válidas. O desempenho foi mensurado de três formas: desempenho final, desempenho na prova de formação geral e desempenho na prova de componente específico. Ademais, foram consideradas as seguintes variáveis institucionais: organização acadêmica, região, modalidade e turno. Os dados foram examinados a partir de modelos de regressão Box Cox Cole Green (BCCG) com zeros ajustados. A partir dos resultados, concluiu-se que as variáveis institucionais foram relevantes para explicar o desempenho. Especificamente, destaca-se que os estudantes matriculados em centros federais de educação tecnológica tiveram desempenho superior aos das outras formas de organização acadêmica. Outro ponto é que os alunos da região Norte performaram pior do que o das outras regiões de modo geral. Todavia, superaram os alunos da região Centro-Oeste nas questões de formação geral. Quanto à modalidade de ensino, verificou-se que alunos do ensino presencial apresentaram performance superior a dos estudantes do ensino a distância (EaD). E os alunos do turno integral tiveram melhores performances de modo geral. Como implicações, aponta-se que as instituições que oferecem cursos de contabilidade e administração na região Norte podem querer aprimorar a qualidade do ensino, assim como as do Centro-Oeste podem querer fazê-lo em relação ao ensino de formação geral. Da mesma forma, o ensino da modalidade EaD pode ser aprimorado e a oferta de cursos em período integral pode ser pensada e, potencialmente, implantada.
Forensic Investigation of Ultrathin Whitetopping Pavements in Florida

Developed in the early 1990s, ultrathin whitetopping (UTW) is a relatively new technique for asphalt pavement rehabilitation. To evaluate the applicability of UTW pavement in Florida, in 1997, the Florida Department of Transportation (FDOT) constructed an experimental UTW pavement in a weigh station along I-10, located in north Florida. The performance of these test sections, however, was less than ideal, with the observation of some early cracking on the concrete surface, which developed into severe cracking with time. Therefore, a forensic investigation was conducted to determine the causes of the problems in these UTW sections, so that lessons could be learned from this experimental project, the use of UTW under Florida's conditions could be adequately assessed, and UTW technology could be properly applied in the future. The scope of work consisted of field evaluation, laboratory testing, and pavement design evaluation. Field evaluation included a pavement condition survey, pavement temperature measurement, nondestructive load testing using a falling weight deflectometer, and slab thickness determination. Laboratory tests were performed to determine concrete and asphalt material properties. Other design and traffic data were also acquired from FDOT. Data collected from the field evaluation and laboratory testing were used in conjunction with a mechanistic UTW pavement design/evaluation procedure to determine the possible causes for premature failure. From this comprehensive evaluation, the primary cause for the failure was found to be inadequate UTW pavement design. The inadequacy of the combination of thickness and slab dimensions contributed to the early cracking of the UTW pavement.
Mitigating the Negative Effect of Drought Stress in Oat (Avena sativa L.) with Silicon and Sulphur Foliar Fertilization

A field experiment was carried out in the 2020–2021 growing season, aiming at investigating the abiotic stress tolerance of oat (Avena sativa L.) with silicon and sulphur foliar fertilization treatments and monitoring the effect of treatments on the physiology, production and stress tolerance of winter oat varieties. In the Hungarian national list of varieties, six winter oat varieties were registered in 2020, and all of the registered varieties were sown in a small plot field experiment in Debrecen, Hungary. The drought tolerance of the oat could be tested, because June was very dry in 2021; the rainfall that month totaled 6 mm only despite a 30-year average of 66.5 mm, and the average temperature for the month was 3.2 °C higher than the 30-year average. Foliar application of silicon and sulphur fertilizers caused differences in the photosynthesis rate, total conductance to CO2, transpiration, water use efficiency, leaf area, chlorophyll content, carotenoid content, thousand kernel weight (TKW) and yield of winter oat. The application of silicon significantly increased the photosynthesis rate (16.8–149.3%), transpiration (5.4–5.6%), air–leaf temperature difference (16.2–43.2%), chlorophyll (1.0%) and carotenoid (2.5%) content. The yield increased by 10.2% (Si) and 8.0% (Si plus S), and the TKW by 3.3% (Si) and 5.0% (Si plus S), compared to the control plots. The plants in the control plots assimilated less CO2 while transpiring 1 m3 water more than in the Si, S or Si plus S fertilized plots. The effect of the silicon varied from 9.0 to 195.4% in water use efficiency (WUE) in the three development stages (BBCH52, BBCH65 and BBCH77). A lower leaf area index was measured in the foliar fertilized plots; even so, the yield was higher, compared to that from the control plots. Great variation was found in response to the foliar Si and S fertilization among winter oat varieties—in WUE, 2.0–43.1%; in total conductance to CO2, 4.9–37.3%; in leaf area, 1.6–34.1%. Despite the droughty weather of June, the winter oat varieties produced a high yield. The highest yield was in ‘GK Arany’ (7015.7 kg ha−1), which was 23.8% more than the lowest yield (‘Mv Kincsem’, 5665.6 kg ha −1). In the average of the treatments, the TKW increased from 23.9 to 33.9 g (41.8%). ‘Mv Hópehely’ had the highest TKW. Our results provide information about the abiotic stress tolerance of winter oat, which, besides being a good model plant because of its drought resistance, is an important human food and animal feed.
Android Malware Analysis and Benchmarking with Deep Learning

Android operating system has been widely used in mobile phones, televisions, smart watches, cars and other Internet of Things applications with its open source structure and wide application market. This widespread use and open-source nature make this operating system and its devices easy and lucrative targets for cyber attackers. One of the most used methods often preferred by attackers is to install malware applications on user devices. As the number of malware programs is increasing, the traditional methods can be insufficient in detecting. Machine learning-based and deep learning-based methods have achieved promising results in malware detection and classification. Deep learning-based methods have an increasing use in malware detection, thanks to the low need for domain expertise and their feature extracting capabilities. Convolutional neural networks (CNN) are popular deep learning methods that are widely used in visual analysis of malware by transforming them to images. In this study, a batch fine-tune transfer learning method was proposed and used on popular CNN models, Xception, ResNet, VGG, Inception, MobileNet, DenseNet, NasNet, EfficientNet. According to the results, the models were analyzed and compared with metrics like accuracy, specificity, recall, precision, F1-score.
A New Method Based on Position Sensitive Detectors to Measure Spatial Angle of Large-Scale Gyroidal

Technology of spatial angle measurement is widely used in the aviation and national defence. Based on research of the spatial angle measurement, a system to measure the spatial angle is devised in this paper, which uses position sensitive detectors (PSD) as the detector and the laser beam emitted from a semiconductor laser as the straightness reference. The detecting system has some characteristics. A novel method is introduced to correct the spatial angle between the incident beam laser and the photoelectric surface of the PSD, which makes the incident beam laser vertical to the PSD. Besides, a back-propagation (BP) neural network is used in this system to compensate the nonlinearity errors of the 2-D PSD, which can improve the credibility of the detectors output data. It also has advantage of reliable data and high precision to measure the spatial angle of the large-scale gyroidal components. Meanwhile, the measuring principle, optical system and electric circuits of the experimental equipment are analyzed in the paper. The result shows that the experimental equipment is more precise and sensitive than old equipment. The relative error can achieve good accuracy. The detecting system has some theoretical research significance in realizing untouched measurement of large-scale gyroidal components in other similar situation.
Distance protection and voltage stability

In this paper the influence of zone 3 distance relays in the case of voltage instability is examined. Different types of relay characteristics are analysed. An adaptive algorithm to prevent undesirable zone 3 operations during voltage instability is proposed. Studies are based on simulations in a fifteen bus system developed by the authors. Data on the mixture of electromechanical, solid-state and numerical distance relays in the Swedish transmission system are presented together with statistics of zone 3 operations from the start of year 1985 until the end of 1998. The investigation shows that undesirable zone 3 distance relay operations during voltage instability can be the difference between a total blackout and a recovering system. Simulations have shown that the adaptive algorithm may save the system from a collapse.
Understanding the Interactions of Happiness, Self-Rated Health, Mental Feelings, Habit of Eating Healthy and Sport/Activities: A Path Model for Abu Dhabi

Understanding the interactions between happiness, self-perception of health, healthy eating behaviors, physical activities, and psychological feelings or symptoms of mental health provides necessary inputs for social policymaking. Using data from the second cycle of the Abu Dhabi Quality of Life survey, this study examined a path analysis of Abu Dhabi residents’ nature of assimilations between these variables. The results point to the significant association between happiness and self-rated health. In addition, the results portray significant direct paths to happiness from three mental feeling variables—“feeling calm and peaceful”, “having lots of energy”, and “feeling downhearted and depressed”. The variable of “often feeling rushed or pressed for time” shows a direct path to self-rated health only. Eating healthy food is significantly associated with both happiness and self-perception of health. In addition, “often doing physical activities” positively influences happiness. The present study enhances and refines policymakers’ understanding of the considered factors on happiness and self-rated health with further elaborations of the mediating roles of specific well-being determinants. Limitations and future research directions are also discussed.
Analysis of quantitative differences in large-aperture size for free-space optical communication systems with circle polarization shift keying and on-off keying in atmospheric turbulence channels

A theoretical model is proposed to study quantitative differences in the size of large-aperture between circle polarization shift keying (CPolSK) and on-off keying (OOK). The quantitative differences can be analyzed with the impact from atmospheric condition, link length, and communication wavelength. Numerical results show that FSO CPolSK systems with longer communication wavelength can reduce the size even smaller than the systems using OOK, while it can be not obvious with increasing link length. Meanwhile, increasing average signal-to-noise ratio (SNR) leads to a reduction of the difference in aperture size. These results can be helpful for FSO systems design.
Theoretical comparison of alternative delivery systems for projects in unpredictable environments

A project delivery process simulation is presented based upon empirical studies in the design‐build environment of semiconductor fabrication facilities (‘fabs’). The model captures key tasks and decisions in design, procurement and construction, as well as design criteria changes along the delivery of a R&D fab utility system. Simulation shows that to involve the specialty contractor from the project start on average expedites project delivery since it prevents delays caused by bidding and by contractors' unfamiliarity with the design product definition. Yet, in unpredictable project environments – environments in which design criteria are likely to change irrespectively of the project progress status – simulation reveals that the averages of construction rework and waste increase if design is prematurely frozen. Assuming that work methods do not change and design criteria remain uncertain, results indicate that a system that combines early contractor involvement with judicious postponement of the design start reduces the average duration of the fab utility delivery in relation to the expected duration if competitive bidding was used, with limited increase in the averages of construction rework and waste. Additional efficiency is gained when specialty contractors relax conservative assumptions on anticipated site conditions. An economic model uses simulation results to assess the tradeoffs between alternative project delivery systems for the case of R&D fabs.
Conducting polymer supported bilayer lipid membrane reconstituted with alamethicin

Ionic electroactive polymers and bioderived materials have been independently demonstrated as actuators, sensors and energy harvesting devices. In an electroactive polymer, the applied electric field between the cathode and anode drives ion transport between the electrodes, impregnated electrolyte and the bulk of the polymer to generate force and displacement. Similarly, in a bioderived material an input stimulus (electrical, chemoelectrical or chemical) applied across the protein in a bilayer lipid membrane (BLM) displaces ions across the membrane barrier and enables sensing and actuation functions. This paper presents a novel architecture for a device that integrates the ionic function of an electroactive polymer and a bioderived material into a thin-film laminated device combining their unique advantages. A conducting polymer (PPy(DBS)) is used as the electroactive polymer and alamethicin-bound bilayer lipid membrane is used as the bioderived material in the thin-film laminated device. Owing to the configuration of the laminated device, the protein regulates the ionic concentration in the conducting polymer and regulates the electrochemical doping/undoping process in the polymer. By electrically connecting the conducting polymer across its thickness, this arrangement provides a mechanism external to the polymer besides electrical field that can control the electrical, mechanical and/or optical properties of the conducting polymer. This paper also presents the fabrication and characterization of the integrated ionic device and presents a template for the development of a novel category of electroactive ionic devices.
Disturbance of Vancomycin Infusion Flow during Multidrug Infusion: Influence on Endothelial Cell Toxicity

Background: Phlebitis is a common side effect of vancomycin peripheral intravenous (PIV) infusion. As only one PIV catheter is frequently used to deliver several drugs to hospitalized patients through the same Y-site, perturbation of the infusion flow by hydration or other IV medication may influence vancomycin exposure to endothelial cells and modulate toxicity. Methods: We assessed the toxicity of variations in vancomycin concentration induced by drug mass flow variations in human umbilical vein endothelial cells (HUVECs), simulating a 24 h multi-infusion therapy on the same line. Results were expressed as the percentage of viable cells compared with a 100% control, and the Kruskal–Wallis test was used to assess the toxicity of vancomycin. Results: Our results showed that variations in vancomycin concentration did not significantly influence local toxicity compared to a fixed concentration of vancomycin. Nevertheless, the loss of cell viability induced by mechanical trauma mimicking multidrug infusion could increase the risk of phlebitis. Conclusion: To ensure that vancomycin-induced phlebitis must have other causes than variation in drug mass flow, further in vitro experiments should be performed to limit mechanical stress to frequent culture medium change.
Effects of Powder Reuse and Spatial Location Dependency on the Powder Characteristics and Defect Structure of Additively Manufactured Ti-6Al-4V Parts

In laser powder bed fusion additive manufacturing (L-PBF AM), different powder characteristics including particle size and morphology may yield different packing states and thus different defect content in the resulting parts. As the powder is spread by the recoater, the packing state may not be uniform on the powder bed, giving rise to location-dependent part performance. In addition, as the powder is reused (a common practice in AM industry), its characteristics continuously evolve, causing the defect content to change from build to build. This study aims to investigate the effects of powder reuse and part location on powder characteristics as well as the defect structure of the parts. Results indicate powder reuse in an L-PBF system may reduce the number of defects in the as-fabricated parts due to the superior packing state of reused powder. Part density was also found to be location-dependent, with more defects near the gas outlet.
Impact of physical, physiological and nutritional factors on the daily productivity of female tea pluckers in Jalpaiguri District, West Bengal

Aims: The purpose of this study was to see if there was any link between physical and physioolgical parameters, nutritional condition of the female tea pluckers and productivity in terms of plucked tea leaves per day in different tea estates of Jalpaiguri District, West Bengal, India Results: Results of our study revealed that out of total female pluckers in our study, 92.27% female tea pluckers were anemic (Hb concentration below 12 gm/dL) and 54.07% female tea pluckers BMI (kg/m) less than 18.5. Prevalence of moderate anemia was much higher in subjects with lower standard of living index. Female tea pluckers with lower hemoglobin concentration, lower physical and physiological parameters showed less productivity in terms of tea leaves plucked per day. Methods: In this study total 293 female individuals including Two hundred and thirty three female tea pluckers between 1845 years of age and sixty control subjects who voluntarily participated were included. Various physical and physiological, socio demographic, health and diet variables were investigated. A variety of physiological and anthropometric characteristics, as well as hemoglobin concentration and productivity in terms of plucked tea leaves per day were also assessed. Conclusion: Workers involved in tea plucking required a sufficient quality food in their daily diet. The nutritional level and health status of this community can be improved by raising the health awareness, providing nutritional assistance. Overall health status of these female tea pluckers are directly related to their earning (wages) from tea garden.
