On Becoming an Online University in an Emergency Period: Voices From the Students at a State University

This study purposes to examine the emergency transition to distance education during the COVID-19 pandemic from the perspective of university students. Based on this purpose, university students were asked open-ended questions about their distance education experience during the COVID-19 pandemic. Transactional Distance Theory was used as the theoretical framework to form the questions and interpret the findings. 441 university students from a state university participated in the study, and 1443 comments were analysed by using text mining techniques. The findings of the study have revealed that students acknowledge the rapid transition positively, but they have also indicated that the effectiveness of distance education is low. The reason for the ineffectiveness was observed as the lack of interactive elements in the content and the low level of communication between faculty members and students. As a result of the findings of the study, several recommendations on how institutions can take precautions are presented.

A tunable laser diode has been made by using a nickel micro-external mirror which is actuated by an electrostatic comb-drive. The mirror was fabricated by nickel surface micromachining. Its displacement was /spl sim/10 /spl mu/m with <2 nm accuracy. Wavelength tunability of /spl sim/20 nm can be obtained by controlling the external cavity.
SIFAT FISIKOKIMIA DAN SENSORIS INSTANT STARCH NOODLE PATI AREN YANG DISUBSTITUSI DENGAN PATI TAPIOKA

The research aimed to identify the physico-chemical and sensory characteristics of aren instant starch noodle (ISN) substituted with 0, 5, 10, 15, 20, and 25% of tapioca starch. The physicochemical and sensory characteristics observed were gelatinization level, water content, white degree, cooking rate, cooking loss, tensile strength, elongation, texture, performance, aroma, taste and viscosity. Corn ISN was used as a comparison. The research results showed that the percentage of the tapioca starch that could substitute the aren starch was in the ranges of 5 – 20%. Substituting with 20% tapioca starch could yield ISN most similar to the corn ISN in which physicochemical and sensory characteristics were acceptable to consumers. However, the water content of the ISN resulted from the research still higher than that of standard category, therefore the time length for drying need to be prolonged.

To do this, servomotor was installed into the let-off unit of the loom using PID controller, additionally fuzzy logic based let-off control was realised. Experimentally obtained warp tension values for each control methods were compared. According to the results, maximal tension values for the conventional, PID and fuzzy logic controlled systems were found to be 53, 45 and 35 cN, respectively. As a result, it is determined that the least warp tension interval and mean warp tension value are in let-off system controlled by fuzzy logic.
Breaking the Data Value-Privacy Paradox in Mobile Mental Health Systems Through User-Centered Privacy Protection: A Web-Based Survey Study

Background Mobile mental health systems (MMHS) have been increasingly developed and deployed in support of monitoring, management, and intervention with regard to patients with mental disorders. However, many of these systems rely on patient data collected by smartphones or other wearable devices to infer patients’ mental status, which raises privacy concerns. Such a value-privacy paradox poses significant challenges to patients’ adoption and use of MMHS; yet, there has been limited understanding of it. Objective To address the significant literature gap, this research aims to investigate both the antecedents of patients’ privacy concerns and the effects of privacy concerns on their continuous usage intention with regard to MMHS. Methods Using a web-based survey, this research collected data from 170 participants with MMHS experience recruited from online mental health communities and a university community. The data analyses used both repeated analysis of variance and partial least squares regression. Results The results showed that data type (P=.003), data stage (P<.001), privacy victimization experience (P=.01), and privacy awareness (P=.08) have positive effects on privacy concerns. Specifically, users report higher privacy concerns for social interaction data (P=.007) and self-reported data (P=.001) than for biometrics data; privacy concerns are higher for data transmission (P=.01) and data sharing (P<.001) than for data collection. Our results also reveal that privacy concerns have an effect on attitude toward privacy protection (P=.001), which in turn affects continuous usage intention with regard to MMHS. Conclusions This study contributes to the literature by deepening our understanding of the data value-privacy paradox in MMHS research. The findings offer practical guidelines for breaking the paradox through the design of user-centered and privacy-preserving MMHS.
Optimization, Characterization, and Antibacterial Activity of Copper Nanoparticles Synthesized Using Senna didymobotrya Root Extract

The economic burden and high mortality associated with multidrug-resistant bacteria is a major public health concern. Biosynthesized copper nanoparticles (CuNPs) could be a potential alternative to combat bacterial resistance to conventional medicine. This study for the first time aimed at optimizing the synthesis conditions (concentration of copper ions, temperature, and pH) to obtain the smallest size of CuNPs, characterizing and testing the antibacterial efficacy of CuNPs prepared from Senna didymobotrya (S. didymobotrya) roots. Extraction was done by the Soxhlet method using methanol as the solvent. Gas chromatography-mass spectrometry (GC-MS) analysis was performed to identify compounds in S. didymobotrya root extracts. Box–Behnken design was used to obtain optimal synthesis conditions as determined using a particle analyzer. Characterization was done using ultraviolet-visible (UV-Vis), particle size analyzer, X-ray diffraction, zeta potentiometer, and Fourier transform infrared (FT-IR). Bioassay was conducted using the Kirby–Bauer disk diffusion susceptibility test. The major compounds identified by GC-MS in reference to the NIST library were benzoic acid, thymol, N-benzyl-2-phenethylamine, benzaldehyde, vanillin, phenylacetic acid, and benzothiazole. UV-Vis spectrum showed a characteristic peak at 570 nm indicating the formation of CuNPs. The optimum synthesis conditions were temperature of 80°C, pH 3.0, and copper ion concentration of 0.0125 M. The FT-IR spectrum showed absorptions in the range 3500–3400 cm−1 (N-H stretch), 3400–2400 cm−1 (O-H stretch), and 988–830 cm−1 (C-H bend) and peak at 1612 cm−1 (C=C stretch), and 1271 cm−1 (C-O bend). Cu nanoparticle sizes were 5.55–63.60 nm. The zeta potential value was −69.4 mV indicating that they were stable. The biosynthesized nanoparticles exhibited significant antimicrobial activity on Escherichia coli and Staphylococcus aureus with the zone of inhibition diameters of 26.00 ± 0.58 mm and 30.00 ± 0.58 mm compared to amoxicillin clavulanate (standard) with inhibition diameters of 20 ± 0.58 mm and 28.00 ± 0.58 mm, respectively.
Measurements of atoms and metastable species in N2 and H2–N2 nanosecond pulse plasmas

Time-resolved, absolute number densities of metastable N2(A3Σ u +, v = 0, 1) molecules, ground state N2 and H atoms, and rotational–translational temperature have been measured by tunable diode laser absorption spectroscopy and two-photon absorption laser-induced fluorescence in diffuse N2 and N2–H2 plasmas during and after a nanosecond pulse discharge burst. Comparison of the measurement results with the kinetic modeling predictions, specifically the significant reduction of the N2(A3Σ u +) populations and the rate of N atom generation during the burst, suggests that these two trends are related. The slow N atom decay in the afterglow, on a time scale longer than the discharge burst, demonstrates that the latter trend is not affected by N atom recombination, diffusion to the walls, or convection with the flow. This leads to the conclusion that the energy pooling in collisions of N2(A3Σ u +) molecules is a major channel of N2 dissociation in electric discharges where a significant fraction of the input energy goes to electronic excitation of N2. Additional measurements in a 1% H2–N2 mixture demonstrate a further significant reduction of N2(A3Σ u +, v = 0, 1) populations, due to the rapid quenching by H atoms accumulating in the plasma. Comparison with the modeling predictions suggests that the N2(A3Σ u +) molecules may be initially formed in the highly vibrationally excited states. The reduction of the N2(A3Σ u +) number density also diminishes the contribution of the energy pooling process into N2 dissociation, thus reducing the N atom number density. The rate of N atom generation during the burst also decreases, due to its strong coupling to N2(A3Σ u +, v) populations. On the other hand, the rate of H atom generation, produced predominantly by the dissociative quenching of the excited electronic states of N2 by H2, remains about the same during the burst, resulting in a nearly linear rise in the H atom number density. Comparison of the kinetic model predictions with the experimental results suggests that the yield of H atoms during the quenching of the excited electronic state of N2 by molecular H2 is significantly less than 100%. The present results quantify the yield of N and H atoms in high-pressure H2–N2 plasmas, which have significant potential for ammonia generation using plasma-assisted catalysis.
Determinan Profitabilitas Bank Umum Syariah Di Indonesia Dengan Tingkat Likuiditas Sebagai Variabel Intervening

This research aims to analyze the effect of capital adequacy ratio (CAR), financing risk (NPF), and operational efficiency (BOPO) on profitability (ROA) with liquidity level (FDR) as an intervening variable in Islamic commercial banks (ICB) in Indonesia in 2015 to 2019. The data used is secondary data in panel data, taken from the annual reports published by each ICB official website. Data analysis used multiple linear regression and path analysis. The results of this study found that CAR has a negative effect on ROA, NPF has a negative effect on ROA, BOPO has a negative effect on ROA, FDR has a positive effect on ROA, CAR has a negative effect on FDR, NPF has a negative effect on FDR, BOPO has a positive effect on FDR liquidity. At the same time, FDR cannot be an intervening variable in the relationship of CAR, NPF, BOPO to ROA. This research provides insight for ICB in maintaining the value of NPF and BOPO to increase the company's net profit.
In Vitro Rapid Multiplication of a Highly Valuable Ornamental Aquatic Plant Anubias Heterophylla

The present study focuses on the development of a micropropagation protocol for true to type plants of Anubias heterophylla, a valuable ornamental aquatic plant. Natural propagation of aquatic species is limited due to the production of a small number of plants with a long cultivation period, disease and requirement of a large space for propagation. Surface-disinfected shoot tip explants were cultured on MS medium containing 0.1 % (w/v) activated charcoal (AC) and supplemented with 6-benzylaminopurine (BAP) at different concentrations (0, 1.0, 3.0 and 5.0 mg/L) either singly or in combination with alpha Naphthalene acetic acid (NAA) and 2,4-Dichlorophenoxy acetic acid (2,4-D) (0.5 and 1.0 mg/L). Among different auxins and cytokinin used, the number of shoots initiated per explant varied significantly among the different auxin and cytokinin combinations. The highest number of shoots per explants (3.60 ± 0.24) was formed in the culture medium containing 1.0 mg/L NAA in combination with 1.0 mg/L BAP, followed by in the culture medium with 3.0 mg/L BAP (2.40 ± 0.24). In the culture medium with 1.0 mg/L NAA and 1.0 mg/L BAP, 100 % of the cultured explants regenerated new shoots within 60 days. The maximum number of roots (19.80 ± 0.20 roots) per explant was observed after 60 days of culture on MS medium contained 0.1 % (w/v) AC and supplemented with 1.0 mg/L NAA and 1.0 mg/L BAP. With a 100% survival rate, the regenerated plantlets were effectively acclimatized to submerged underwater environments. Plantlets exhibited phenotypic traits that were comparable to those of their donor plant. This protocol is suited for commercial Anubias heterophylla propagation in the aquarium industry. HIGHLIGHTS The development of a micropropagation protocol for true to type plants of Anubias heterophylla The initiation of aseptic cultures of Anubias heterophylla from shoot tip explants Optimization of culture medium for shoot proliferation Rooting micro shoots and hardening of rooted micro shoots
Planning to Minimize the Human Muscular Effort during Forceful Human-Robot Collaboration

This work addresses the problem of planning a robot configuration and grasp to position a shared object during forceful human-robot collaboration, such as a puncturing or a cutting task. Particularly, our goal is to find a robot configuration that positions the jointly manipulated object such that the muscular effort of the human, operating on the same object, is minimized while also ensuring the stability of the interaction for the robot. This raises three challenges. First, we predict the human muscular effort given a human-robot combined kinematic configuration and the interaction forces of a task. To do this, we perform task-space to muscle-space mapping for two different musculoskeletal models of the human arm. Second, we predict the human body kinematic configuration given a robot configuration and the resulting object pose in the workspace. To do this, we assume that the human prefers the body configuration that minimizes the muscular effort. And third, we ensure that, under the forces applied by the human, the robot grasp on the object is stable and the robot joint torques are within limits. Addressing these three challenges, we build a planner that, given a forceful task description, can output the robot grasp on an object and the robot configuration to position the shared object in space. We quantitatively analyze the performance of the planner and the validity of our assumptions. We conduct experiments with human subjects to measure their kinematic configurations, muscular activity, and force output during collaborative puncturing and cutting tasks. The results illustrate the effectiveness of our planner in reducing the human muscular load. For instance, for the puncturing task, our planner is able to reduce muscular load by \( 69.5\% \) compared to a user-based selection of object poses.
A Comparative Analysis of Modeling and Predicting Perceived and Induced Emotions in Sonification

Sonification is the utilization of sounds to convey information about data or events. There are two types of emotions associated with sounds: (1) “perceived” emotions, in which listeners recognize the emotions expressed by the sound, and (2) “induced” emotions, in which listeners feel emotions induced by the sound. Although listeners may widely agree on the perceived emotion for a given sound, they often do not agree about the induced emotion of a given sound, so it is difficult to model induced emotions. This paper describes the development of several machine and deep learning models that predict the perceived and induced emotions associated with certain sounds, and it analyzes and compares the accuracy of those predictions. The results revealed that models built for predicting perceived emotions are more accurate than ones built for predicting induced emotions. However, the gap in predictive power between such models can be narrowed substantially through the optimization of the machine and deep learning models. This research has several applications in automated configurations of hardware devices and their integration with software components in the context of the Internet of Things, for which security is of utmost importance.
Utilization and impact of online sourcing of information on the academic performance of medical students in a Nigerian university

This study examines the use of internet facilities by medical students of the Lagos State University College of Medicine (LASUCOM) Ikeja. Apart from serving as a learning tool, the sourcing of information through the internet motivates students to undertake research and helps them to develop skills in collecting and analyzing data. A two-part questionnaire was developed and used to elicit the necessary information for the study. Three hundred and five copies of the questionnaire were distributed to the students in the College of Medicine Ikeja, Nigeria, out of which 250 copies were completed, returned and used for the study. This constitutes 81.9% response rate. Findings showed that the medical students have access to internet facilities, although majority of the respondents (46.4%) have access through cybercafes around the campus. On the average, respondents spent at least between 30 min and 1 h accessing the internet on a weekly basis. The study also revealed that medical students consulted the PUBMED database regularly and that access to myriads of online resources through the internet has a positive effect on the academic performance of the respondents. The study recommends increase in the number of computer terminals for accessing internet facility in the College including acquisition of internet ready computers for the College library. Another vital recommendation is the need for an increase in the bandwidth of the hub for the internet connectivity in the College. Key words: Lagos State University College of Medicine, Ikeja, Nigeria, internet use, academic performance, students’ usage, education.
AN ANALYSIS OF THE USE OF WEB DESIGN CONVENTIONS IN COMPANY WEBSITES

Web usability advocates stress the importance of simplicity, consistency, and following web design conventions. Without this, users may get lost, feel confused or frustrated, or may abandon a site. Web usability authorities have made anecdotal remarks about the failure of sites to follow web conventions, but there have been few research attempts to address this issue. This study examines the websites of INC. 500 companies using five design measures related to link appearance and navigation. The results revealed that company practices with respect to these web design conventions are highly variable. This makes many websites more unpredictable than they otherwise would be and it imposes a greater cognitive load on web users. The results suggest that many websites might reexamine their sites from a usability perspective.
Digital technologies (DT) adoption in agri-food supply chains amidst COVID-19: an approach towards food security concerns in developing countries

Purpose This study aims to explore the critical factors for digital technologies (DT) adoption to develop a sustainable agri-food supply chain (AFSC). As the developing countries are struggling to survive during COVID-19, DT adoption in AFSC can bring resilience and minimizes the food security concerns. Design/methodology/approach The study has used Fuzzy Delphi and fuzzy decision-making trial and evaluation laboratory (DEMATEL) methods for identifying the critical success factors (CSFs) for DT adoption and inter-relationship among them to explore the crucial factors for food security across AFSC. Findings The research reveals that “Digital Technologies, Logistics and infrastructure” is the most crucial CSF for managing food security in developing economy during the COVID-19 situation. This factor supports the decision-makers to manage data for demand and supply management and helps to survive and sustain in the disruptive environment. The findings of the study will help farmers and supply chain partners to manage the smooth flow of food items from source to end-users during a disruptive environment. The sourcing, manufacturing and delivery methods are needed to be changed with DT inclusion and may support to redesign their internal systems for improvisation. This shorter AFSC will enhance the resilience in AFSCs. Research limitations/implications The emergency situation raised by the COVID-19 pandemic has brought global food security concerns. Adoption of DT across AFSCs can strategically reduce food waste and optimize the demand and supply balance. Originality/value The study aims to build a comprehensive framework by identifying the CSFs to develop resilient and sustainable AFSC amidst COVID-19.
Optimal Beamforming for IRS-Assisted SWIPT System with an Energy-Harvesting Eavesdropper

In this paper, we study a simultaneous wireless information and power transfer (SWIPT) system aided by the intelligent reflecting surface (IRS) technology, where an AP transmits confidential information to the legitimate information receiver (IR) in the presence of an energy harvesting (EH) receiver that could be a potential eavesdropper. We aim to maximize the secrecy rate at the legitimate IR by jointly optimizing the information beamforming vector and the energy transfer beamforming vector at the access point (AP), and the phase shift matrix at the IRS, subject to the minimum harvested power required by the EH receiver. The semi-definite relaxation (SDR) approach and the alternating optimization (AO) method are proposed to convert the original non-convex optimization problem to a series of semi-definite programs (SDPs), which are solved iteratively. Numerical results show that the achievable secrecy rate of the proposed IRS-assisted SWIPT system is higher than that of the SWIPT system without the assistance of the IRS.
