Patient Satisfaction Determinants of Inpatient Healthcare

The aim of the study was to analyse and evaluate the determinants influencing the overall satisfaction of patients with inpatient healthcare in the conditions of the Czech Republic. A total of the 1425 patients, who experienced hospitalisation and agreed to participate, were questioned in the study. A research questionnaire was used to obtain data on satisfaction with hospitalisation. The subject of the research consisted of the indicators related to the following factors: (i) satisfaction with the hospital, clinic, room and meals; (ii) satisfaction with medical staff—nurses, physician expertise and other staff; (iii) the quality of the treatment provided; (iv) satisfaction with leaving the hospital. The formulated statistical hypotheses were evaluated through structural equation modelling. The results of the analyses brought interesting findings. Satisfaction with medical staff is the most significant factor which has a positive effect on satisfaction with hospitalisation. Physician expertise (with trust and good communication skills) is more important for patients than satisfaction with nurses or other staff. The results obtained from the study represent valuable information for policymakers, regional healthcare plans, as well as for managers of hospitals.
Cytotoxic Effect In Vitro of Acalypha monostachya Extracts over Human Tumor Cell Lines

Acalypha monostachya (A. monostachya) is a plant that is used in traditional medicine as a cancer treatment; however, its effect has not been validated. In this study, the potential cytotoxic effects and morphological changes of A. monostachya were evaluated in human tumor cell lines. The aqueous (AE), methanolic (ME), and hexane (HE) extracts were obtained, and flavonoid-type phenolic compounds were detected, which indicates an antineoplastic effect. We observed a time-dependent and concentration-selective toxicity in human tumor cells. Additionally, the ME and HE showed the greatest cytotoxic effect at minimum concentrations compared to the AE, which showed this effect at the highest concentrations. All extracts induced significant morphological changes in tumor cells. The HeLa (cervix carcinoma) cells were more sensitive compared to the MDA-MB-231 (triple-negative breast cancer) cells. In conclusion, we demonstrated a cytotoxic in vitro effect of A. monostachya extracts in tumoral human cell lines. These results show the potential antineoplastic effects of A. monostachya in vitro. Hereafter, our lab team will continue working to usefully isolate and obtain the specific compounds of A. monostachya extracts with cytotoxic effects on tumor cells to find more alternatives for cancer treatment.
A comprehensive study on multi-objective design optimization of spur gear

Abstract The paper presents procedure for design optimization of a spur gear set with the objective of minimization of the gear weight, contact stress along path of contact and optimum film thickness at the contact point. Particle swarm optimization, particle swarm optimization based teaching learning optimization and Jaya algorithms are presented here to ensure the remarkable reduction in weight and contact stress of a profile modified spur gear set with adequate film thickness at the point of contact. The parametric and sensitivity analysis performed here recommended the manufacturing tolerance to be maintained for the different critical design variables. The contact stress analysis using finite element method suggested the use of negatively altered tooth sum spur gear for compact design with better strength balance and scoring resistance. The optimized values of addendum co-efficient within the design space significantly improves the gear design as compared to the conventional design.
Investigating Problem Solving Skills and Chemistry Learning Experiences of Higher Education Base on Gender and Grade Level Differences

The purpose of this study was to investigate the problem-solving skills (PSS) and chemistry learning experiences (LE) of teacher candidates. 191 pre-service chemistry teacher (130 women, 61 men) were taken as the research sample using the purposive random sampling technique. The research design used a cross-sectional survey with focus group interviews. The quantitative data obtained were analyzed using the MANOVA test and while the interview data using the Patton analysis technique. The research findings show that: 1) the level of the chemistry learning experience of pre-service chemistry teacher (LE) is higher than the ability of problem-solving skills (PSS); 2) the level of ability of female chemistry teacher candidates for PSS and LE was found to be higher than that of males; (3) there are differences in PSS and LE based on grades levels, but there is no difference based on gender; 4) there is a difference in PSS and LE between freshman, sophomore, and junior grades. The findings of the interview are relevant to the results of the survey which proved that male and female students both have positive attitudes towards chemistry, however, it was found that there were differences in PSS and LE between grade level (1stgrade, 2stgrade, 3st grade). Thus, it is suggested that the learning process in universities prioritizes the development of LE and PSS in chemistry learning so as to improve the soft skills and academic achievement of prospective chemistry teachers.
A Data Quality Assessment Approach in the SmartWork Project's Time-series Data Imputation Paradigm

: The plethora of collected data streams of the SmartWork project’s sensing system is often accompanied by missing values, yielding the need for estimating these missing values through imputation, which may prove unnecessary or computationally expensive in relation to the outcome. This work introduces a data quality assessment approach that allows for decision making regarding the need/efﬁciency of data completion in order to save system computational resources and ensure quality of imputed data. Preliminary validation of the proposed approach is performed by assessing the correlation between the proposed data quality assessment scores and the normalized mean square error of the imputation on various simulated missing patterns. The results reinforce our initial hypothesis that the suggested score is a suitable data quality indicator, correlating well with the potential errors introduced by imputation in the case of a given batch of input data.
Prevalence of Acne Inversa (Hidradenitis Suppurativa) in China: A Nationwide Cross-Sectional Epidemiological Study

Abstract Objective: This study was performed to estimate the prevalence of hidradenitis suppurativa (HS) in China and describe the demographic and clinical features of HS in the Chinese population. Methods: This multicenter clinic-based cross-sectional study was conducted in dermatology clinics within 19 hospitals located in 15 cities/provinces across China from September to October 2020. The prevalence of HS was calculated as the percentage of patients with HS among all visitors at participating clinics during the 1-month study period. HS was independently diagnosed by two certified dermatologists at each site. All visitors at participating clinics were screened, and all patients with HS were invited to participate in a questionnaire survey to elucidate the demographics and clinical features of HS in the Chinese population. Results: We identified 92 patients with HS among 274,742 visitors at participating clinics. The prevalence rate was 0.03349% or 33.49 per 100,000 population (95% confidence interval, 26.64-40.32), and the female:male ratio was 1.0:4.7. Conclusion: The overall prevalence of HS in China was lower than that in Western and other Asian countries with a predominance of male patients.
Erosion rates in a wet, temperate climate derived from rock luminescence techniques

Abstract. A new luminescence erosion meter has huge potential for inferring erosion rates on sub-millennial scales for both steady and transient states of erosion, which is not currently possible with any existing techniques capable of measuring erosion. This study applies new rock luminescence techniques to a well-constrained scenario provided by the Beinn Alligin rock avalanche, NW Scotland. Boulders in this deposit are lithologically consistent and have known cosmogenic nuclide ages and independently derived Holocene erosion rates. We find that luminescence-derived exposure ages for the Beinn Alligin rock avalanche were an order of magnitude younger than existing cosmogenic nuclide exposure ages, suggestive of high erosion rates (as supported by field evidence of quartz grain protrusions on the rock surfaces). Erosion rates determined by luminescence were consistent with independently derived rates measured from boulder edge roundness. Inversion modelling indicates a transient state of erosion reflecting the stochastic nature of erosional processes over the last ∼4.5 kyr in the wet, temperate climate of NW Scotland. Erosion was likely modulated by known fluctuations in moisture availability and to a lesser extent temperature, which controlled the extent of chemical weathering of these highly lithified rocks prior to erosion. The use of a multi-elevated temperature, post-infra-red, infra-red stimulated luminescence (MET-pIRIR) protocol (50, 150 and 225 ∘C) was advantageous as it identified samples with complexities that would not have been observed using only the standard infra-red stimulated luminescence (IRSL) signal measured at 50 ∘C, such as that introduced by within-sample variability (e.g. surficial coatings). This study demonstrates that the luminescence erosion meter can infer accurate erosion rates on sub-millennial scales and identify transient states of erosion (i.e. stochastic processes) in agreement with independently derived erosion rates for the same deposit.
Application of Computerized Learning Games in Teaching at Karak Schools: Challenges Encountered when Teaching English Language

This study aimed at examining the level of applying computerized learning games in teaching among various schools in Karak metropolis. The study further evaluates the challenges encountered by teachers and the obstacles faced by students in learning English language. To collect the required data for the study, two survey questionnaires were used among the selected teachers. The targeted respondents consist of 82 male and female teachers of English language who teach students at third grade in various schools within the Karak metropolis. Results showed that the level of employing English teachers for computerized learning games in teaching of English for the third grade among various schools of Karak was to a medium degree, while the obstacles faced by students in learning English from the teacher’s point of view was at a high degree. Further results showed that, the attitudes of teachers toward the use of computerized learning games in learning English were high. In view of these findings, there is need to recognize the significance and encourage the application of computerized learning games in the teaching of English language to students at the basic stage.
Microstructures and Reaction Properties of Ti/Ni, Ti/Al and Ni/Al Multilayer Films

Reactive multilayer thin films are well-defined heterogeneous nanostructured energetic materials which can release chemical energy through a self-sustainable reaction. They have attracted intense interests due to potential applications in diverse fields such as joining, igniters, and high energy density power sources. In this paper, Ti/Ni, Ti/Al and Ni/Al multilayer films were prepared by magnetron sputtering. The reaction kinetics, microstructure and phase variation of these free-standing films are comparatively investigated. During slow heat reaction, the reaction products of reactive multilayer Ti/Ni nanofoils change from B2-TiNi austenite phase into TiNi3, illustrating an evolution of the phase transformation during reaction. These intermediate phases are also identified by slow heating and quenching. The fast speed imaging exhibits that the front speed is 0.47m/s, 0.8m/s and 3m/s respectively for as-deposited Ti/Ni, Ti/Al, and Ni/Al films. Differential thermal analysis yields that the corresponding releasing heat is 551.44 J/g, 434.18 J/g, and 562.5 J/g for these three composites. The theoretical minimum multilayer thickness for melting a tin solder layer has been calculated on the base of these characterizations, which proved the application potential of joining using the as-deposited film.
Two-dimensional cyano-bridged coordination polymer of Mn(H2O)2[Ni(CN)4]: structural analysis and proton conductivity measurements upon dehydration and rehydration

Two-dimensional (2D) materials are widely investigated as electronic or catalytic materials as well as being conventionally used as adsorbents for accommodating guest molecules in the interlayer spaces. 2D coordination polymers have flexible structures, which are transformed even by a weak external stimulus such as a humidity change. Here we report a structural analysis and proton conductivity measurements of a 2D cyano-bridged coordination polymer of the Mn[Ni(CN)4] system upon dehydration and rehydration. The structure of the sample at high humidity was determined by single-crystal diffraction, while the structure at low humidity was solved by Rietveld analysis of synchrotron powder diffraction data. At high humidity, the material contains coordinated and non-coordinated water molecules as [Mn(H2O)2Ni(CN)4]·3H2O. These water molecules were further analyzed by TG-DTA and classified into three types: (i) two coordinated molecules, (ii) two weakly adsorbed non-coordinated molecules and (iii) a strongly adsorbed non-coordinated molecule. These water molecules play a key role in crystal structure transformation upon dehydration/hydration, where the two-dimensional coordination network is retained but the curvature changes by tilting of MnO6 octahedra owing to the change in hydrogen bonds between the water molecules. Because the water molecules form hydrogen bonding networks, proton conductivity was expected. Thus, we investigated the proton conductivity using the single-crystal AC impedance method and found that the crystals were insulating. This in turn suggests that the water molecules in the interlayer spaces do not dissociate into protons mostly, and the spaces are non-ionic.
Validation of the Korean Version of Impact of Event Scale—Revised (IES-R) in Korean Nurses during the COVID-19 Pandemic

Nurses working amid the COVID-19 pandemic are at increased risk of developing post-traumatic stress disorder (PTSD). This study was conducted to verify the reliability and validity of the Korean version of Impact of Event Scale—Revised (IES-R), one of the most used tools for assessing trauma. Secondary data of 249 nurses who performed face-to-face nursing tasks during the COVID-19 pandemic, collected through an online survey, were analyzed by conducting a factor analysis of the K-IES-R and testing the internal consistency and concurrent validity with the Perceived Stress Scale (PSS), Generalized Anxiety Disorder Screener (GAD-7), and Dimensions of Anger Reactions-5 (DAR-5). The result of an exploratory factor analysis of the K-IES-R supported a three-factor structure of intrusion, avoidance, and sleep disturbance, with CMIN/DF = 2.98, RMSEA = 0.09, SRMR = 0.03, CFI = 0.93, and TLI = 0.90. The Cronbach’s alpha of each subscale was 0.88–0.94. The total K-IES-R score and each factor’s value showed a significant correlation (moderate or higher) with the PSS, GAD-7, and DAR-5. The K-IES-R was verified as a useful tool for assessing post-traumatic stress symptoms in nurses who directly perform nursing tasks in crises such as COVID-19. This study suggests the tool be used for early assessment of post-traumatic stress symptoms in nurses and providing appropriate interventions.
JaVerT: JavaScript Verification and Testing Framework: Invited Talk

We present a novel, unified approach to the development of compositional symbolic execution tools, which bridges the gap between traditional symbolic execution and compositional program reasoning based on separation logic. We apply our approach to JavaScript, providing support for full verification, whole-program symbolic testing, and automatic compositional testing based on bi-abduction.
Listening to speech in noisy scenes: Antithetical contribution of primary and non-primary auditory cortex

Invasive and non-invasive electrophysiological measurements during “cocktail-party”-like listening indicate that neural activity in human auditory cortex (AC) “tracks” the envelope of relevant speech. Due to the measurements’ limited coverage and/or spatial resolution, however, the distinct contribution of primary and non-primary auditory areas remains unclear. Using 7-Tesla fMRI, here we measured brain responses of participants attending to one speaker, without and with another concurrent speaker. Using voxel-wise modeling, we observed significant speech envelope tracking in bilateral Heschl’s gyrus (HG) and middle superior temporal sulcus (mSTS), despite the sluggish fMRI responses and slow temporal sampling. Neural activity was either positively (HG) or negatively (mSTS) correlated to the speech envelope. Spatial pattern analyses indicated that whereas tracking in HG reflected both relevant and (to a lesser extent) non-relevant speech, right mSTS selectively represented the relevant speech signal. These results indicate that primary and non-primary AC antithetically process ongoing speech suggesting a push-pull of acoustic and linguistic information.
Working in a Smart Home-office: Exploring the Impacts on Productivity and Wellbeing

Following the outbreak of the Coronavirus (COVID-19) pandemic, many organisations have shifted to remote working overnight. The new reality has created conditions to use smart home technologies for work purposes, for which they were not originally intended. The lack of insights into the new application of smart home technologies has led to two research objectives. First, the paper aimed to investigate the factors correlating with productivity and perceived wellbeing. Second, the study tried to explore individuals' intentions to use smart home offices for remote work in the future. 528 responses were gathered from individuals who had smart homes and had worked from home during the pandemic. The results showed that productivity positively relates to service relevance, perceived usefulness, perceived ease of use, hedonic beliefs, control over environmental conditions, innovativeness and attitude. Task-technology fit, service relevance, attitude to smart homes, innovativeness, hedonic beliefs, perceived usefulness, perceived ease of use and control over environmental conditions correlate with perceived wellbeing. The intention to work from smart home-offices in the future is determined by perceived wellbeing. Findings contribute to the research on smart homes and remote work practices, by providing the first empirical evidence about the new applications and outcomes of smart home use in the work context.
Irrigation Frequency and Plant Density Affect Phenology and Crop Growth of Haricot Bean (Phaseolus vulgaris L.)

A field study was conducted involving a factorial combination of two haricot bean (Phaseolus vulgaris L.) varieties ‘Roba-1’ and ‘Mexican-142’ with three irrigation frequencies at 60, 90 and 120 mm cumulative pan evaporation (CPE) using an IW/CPE ratio thereby fixing the depth of irrigation water (IW) to 60 mm and three planting density levels (150000, 250000, 350000 plants/ha) to investigate their effects on phenology and crop growth at Tony farm, Dire Dawa during winter (bega). A split plot design was laid out with irrigation frequency as the main plot while a combination of planting density and variety served as sub-plots with three replications each. Days to maturity and crop growth parameters of haricot bean increased as irrigation frequency increased from 120 to 90 then to 60 mm CPE. Variety significantly influenced phenological stage, specifically days to flowering and days to maturity. Plant height and leaf number were significantly higher for ‘Mexican-142’, with a 17.7 and 29.0% increase, respectively. As plant density increased, it significantly (P < 0.05) decreased leaf area and leaf number, and increased the leaf area index of beans. The highest seed yield/plant was recorded with the minimum plant density (150000 plants/ha) and lowest seed yield/plant with the highest plant density (350000 plants/ha). The increased irrigation frequency from 120 to 60 mm CPE significantly increased seed yield/plant from 38.22 to 59.94 g. _____________________________________________________________________________________________________________
Study of magnetic fluctuations and ordering in uranium compounds by heat capacity and neutron scattering measurements

URhGe is the first ferromagnet discovered that shows superconductivity at ambient pressure. It shows a rich temperature-magnetic field phase diagram with a re-emergence of superconductivity at high magnetic field where the moments rotate. This suggests that the quantum fluctuations associated with the moment rotation may provide the pairing interaction for superconductivity. The objective of this thesis was to study these critical fluctuations with inelastic neutron scattering and heat capacity measurements, using the latter to test the bulk nature of the superconductivity and determine the types of gap nodes to help test this hypothesis. To perform the heat capacity measurements, it was necessary to develop an apparatus that measures milligram samples in the temperature range 50-1000 mK, and magnetic field range 0-12 T. The field exerts a mechanical force upon the sample, which causes it to rotate, perturbing the system destructively. The apparatus developed in this thesis overcomes this difficulty by holding the sample with tensioned kevlar wires. Testing was done by making measurements on UPt3, a well characterised superconductor. It was then used to measure URhGe in zero magnetic field. The extension to measurements in high magnetic field were not performed however, due to the structural integrity of the apparatus being weak this was in an attempt to reduce the thermodynamic signature of the background. After many iterations of apparatus design and build, the device was proved not appropriate for high fields. A discussion of the zero-field data, as well as the design and build process, is given. The Curie temperature of URhGe is suppressed with magnetic field (applied along the b-axis), reaching zero temperature at the moment rotation transition referred to above. Small angle neutron scattering (SANS) was measured at both zero and finite fields to detect the evolution and relaxation of the
Sustainability and Wellbeing in Healthcare Facilities. An Investigation Inside a Historic Hospital

Received: 5 October 2021 Accepted: 25 October 2021 Sustainability, health and well-being are strictly connected. The WHO has recently highlighted the importance of designing, management, organization and also retrofitting and refurbishment interventions for health care facilities based on climate-resilient and environmentally sustainable health criterion. In this study we propose a practical method based on the combination of physical-real and virtual information, i.e. the integration between continuous monitoring system and transient simulations, for the assessment of microclimatic and ventilation parameters, user influx/presence and behaviour, real operation (on demand) of plants and control/regulation system adjustment. The method is based on a system thinking that assures people and environment health, safety, quality of services and management, reducing energy and facility costs. Findings provided the fundamentals for training health workers and people/patients, aiming at conscious interaction for health and wellbeing protection, but also environmental sustainability and management quality. This is particularly important for healthcare environments housed in historic buildings, such as the one studied.
