Partial Least Square-Structural Equation modeling (PLS-SEM) is applied as a statistical analysis to this study. The results of data analysis showed that the location has a positive effect on patient satisfaction. In addition, facilities have a positive effect on patient satisfaction. Meanwhile, location does not have a positive effect on patient loyalty and facilities do not have a positive effect on patient loyalty. Finally, patient satisfaction has a positive effect on patient loyalty.
Improvement of acceptance of mobile commerce

Although almost 80 percent of the people has a smartphone these days, only 10 percent of online purchases are made via smartphones. There seems to be no clear reasons given in existing literature as for why this percentage is so low. This research aims to discover the facilitating and impeding factors for the attitude of consumers towards mobile purchasing. A literature review was conducted and the factors that are extracted from various models that explain the adoption process are tested through a questionnaire. Analyzes is done after collecting data from 376 valid respondents. The findings show that, in contradiction with literature found in the literature review, ‘perceived ease of use’ of the technology acceptance model is the most critical factor for consumers to either purchase or not purchase via smartphones. In addition, security and compatibility of websites contribute to one’s attitude towards purchasing via smartphones. The results of this research are useful for companies to keep in mind when adjusting their mobile strategy, for example moving from IT-driven to business-driven. This study contributes to literature by critically analyzing previous studies and gaining alternative results with respect to previous studies. Future research should focus on the technical aspects of smartphones and websites to further influence higher adoption rates.
Prevalence of Stress, and Its Impact on Academic Performance Among Undergraduate Medical Students in University of Cyberjaya

Introduction: Chronic stress among medical students affects academic performance. Among the most established source of stress is academic-related stressors, such as exams. This study aimed to evaluate the prevalence of stress level, relationship between stress levels and academic performances among medical students at University of Cyberjaya. Methods: A cross-sectional online survey was conducted on 216 targeted respondents based on single proportion formula for sample size calculation. Data were collected using self-administered questionnaire to obtain respondents demographic and evaluate stress level using Perceived Stress Scale Questionnaire (PSS-10) and Medical Stress Questionnaire (MSSQ). Data were analysed using IBM SPSS Statistics for Windows, Version 23.0 and Spearman correlation analysis was used to determine the association between stress level and academic performance. Results: Of 216 targeted respondents, 197 (91%) responded, with majority (73.6%) aged 22 years and above. The majority of students (87%) felt stress within six months, having mild stress level (45.2%), moderate stress levels (40.1%), severe stress (8.1%) and low stress level (6.6%). Academic-related was found to be the most prevalent stressor (Score 2.43, SD 0.728). The relationship between perceived stress level and GPA showed a significant correlation at (r = -0.95, p<0.01) indicating the higher the stress level, the lower the academic performance. Conclusion: The prevalence of stress among medical students of UOC was high, and the higher stress level was significantly correlated with lower academic performance.
Reliability Prediction and Web Service Selection Using Soft Computing Techniques for Service-Oriented Systems

Building a wide variety of distributed systems is a complex task these days. Since, service oriented architecture (SOA) is a major framework for distributed systems, it’s reliability is the major concern while developing a related software. The assessment of reliability in service-oriented systems (SOS) mainly depends on the accessibility of web-services, which leans on different parameters i.e. unpredictable internet, communication links and the location of web services. Hence, reliability needs to be predicted for the better functioning of a system. Selection of an optimal web-service is also an important concern in SOS. Since, for an abstract task to perform in SOS, a large number of functionally equivalent web service candidates are available. The same web service candidate can perform differently with different users. So, a technique is required for building the personalized web service ranking framework for designers. Hence, for predicting the reliability of SOS and for selection of an optimal web service candidate from functionally equivalent set of web service candidates a most effective approach is desired. In this work, a novel methodology is proposed for predicting the reliability of Web Service candidate which basically uses the past failure experience of similar service users and a personalized framework for selection of an optimal Web Service candidate from functionally equivalent candidates' set which basically is associated with the past Web-Service usage experience of similar users. In this work, no additional invocation of Web service is required. The experimental results are compared with many other techniques proposed by other authors in literature which shows the effectiveness of proposed approach.
Hardware in the Loop (HIL) Analysis of Fuzzy Controller for Ball and Beam System

Ball and beam system is a nonlinear and unstable system which is used as an applied sample in research laboratories as a tool to represent the performance of different control algorithms. The present study utilizes hardware in the loop realization of classic (PID type) and fuzzy controllers by Sugeno fuzzy inference approach in order to evaluate their performances. All activities for design and simulation of controller were performed by MATLAB and Simulink software. Then, the simulation environment of MATLAB was linked to the operator interface as well as actuators and sensors in hardware in the loop structure by writing a real time kernel through DAQ interface cards. Simulation results show the appropriate performance of fuzzy controller in comparison to PD and PID controllers. By using fast processors for implementation of fuzzy controller, settling time, overshoot percentage and steady state error of the closed loop system were significantly improved in comparison to the common classic structure. Also, all simulation results were verified by hardware in the loop test.
Modeling vaccination and control strategies for outbreaks of monkeypox at gatherings

Background The monkeypox outbreak in non-endemic countries in recent months has led the World Health Organization (WHO) to declare a public health emergency of international concern (PHEIC). It is thought that festivals, parties, and other gatherings may have contributed to the outbreak. Methods We considered a hypothetical metropolitan city and modeled the transmission of the monkeypox virus in humans in a high-risk group (HRG) and a low-risk group (LRG) using a Susceptible-Exposed-Infectious-Recovered (SEIR) model and incorporated gathering events. Model simulations assessed how the vaccination strategies combined with other public health measures can contribute to mitigating or halting outbreaks from mass gathering events. Results The risk of a monkeypox outbreak was high when mass gathering events occurred in the absence of public health control measures. However, the outbreaks were controlled by isolating cases and vaccinating their close contacts. Furthermore, contact tracing, vaccinating, and isolating close contacts, if they can be implemented, were more effective for the containment of monkeypox transmission during summer gatherings than a broad vaccination campaign among HRG, when accounting for the low vaccination coverage in the overall population, and the time needed for the development of the immune responses. Reducing the number of attendees and effective contacts during the gathering could also prevent a burgeoning outbreak, as could restricting attendance through vaccination requirements. Conclusion Monkeypox outbreaks following mass gatherings can be made less likely with some restrictions on either the number and density of attendees in the gathering or vaccination requirements. The ring vaccination strategy inoculating close contacts of confirmed cases may not be enough to prevent potential outbreaks; however, mass gatherings can be rendered less risky if that strategy is combined with public health measures, including identifying and isolating cases and contact tracing. Compliance with the community and promotion of awareness are also indispensable to containing the outbreak.
Fear of relapse and quality of life in multiple sclerosis: the mediating role of psychological resilience

The goal of this study was to examine the mediating role of psychological resilience in the relationship between fear of relapse and quality of life in a sample of patients with multiple sclerosis (PwMS). This cross-sectional study was developed online. A total of 240 PwMS were surveyed using the Multiple Sclerosis Quality of Life inventory, the Fear of Relapse Scale and the Connor-Davidson Resilience Scale. To perform the mediation analysis PROCESS macro was used. In our study, fear of relapse was a predictor of psychological resilience and quality of life, and psychological resilience was a predictor of quality of life. Finally, psychological resilience showed a mediating role in the relationship between fear of relapse and quality of life. Considering that resilience is a modifiable variable, the implementation of interventions aimed at enhancing resilience can have a favorable impact on the psychological well-being and quality of life of patients with multiple sclerosis.
A psycho-cognitive model for exertional heatstroke: theory and preliminary testing using self-report measures in a case-control study

Background. Exertional heatstroke (EHS) is the most serious condition in the spectrum of heat illnesses that can occur during sport competition or physical effort under environmental stress. Despite substantial progress in understanding the pathophysiology of EHS, evidence appears to be insufficient for confining its description to a purely physiological syndrome. Objective. We introduce a psycho-cognitive model for EHS, and we initiate its experimental validation using self-report measures in a case-control study. Our working hypothesis is that EHS might be the consequence of the alteration of cost-benefit trade-off associated with prolonged physical activity. Specifically, we propose that EHS might result from the overvaluation of benefits associated with physical effort, as a consequence of overmotivation to succeed, and/or the undervalued costs of effort exertion that result from low interoceptive body awareness, i.e. disrupted processing of signals about the internal (physiological) state of the body. Results. Our psychometric data showed that subjects with a history of EHS (cases, N=51) self-report lower interoceptive body awareness compared to healthy subjects (controls, n=43), but do not differ in terms of motivational trait (global motivation). In addition, we found that cases show a less developed trait mindfulness compared to controls. Conclusion. We provide theoretical foundations and preliminary support for a psycho-cognitive model of EHS. Our findings suggest that relatively simple measures (self-report questionnaires) may have utility in identifying intrinsic (individual-specific) risk factors for EHS. Psycho-cognitive approach of the EHS could potentially lead to novel prevention strategies to mitigate its risk in sport competitions.
Demographic and Viral-Genetic Analyses of COVID-19 Severity in Bahrain Identify Local Risk Factors and a Protective Effect of Polymerase Mutations

A multitude of demographic, health, and genetic factors are associated with the risk of developing severe COVID-19 following infection by the SARS-CoV-2. There is a need to perform studies across human societies and to investigate the full spectrum of genetic variation of the virus. Using data from 869 COVID-19 patients in Bahrain between March 2020 and March 2021, we analyzed paired viral sequencing and non-genetic host data to understand host and viral determinants of severe COVID-19. We estimated the effects of demographic variables specific to the Bahrain population and found that the impact of health factors are largely consistent with other populations. To extend beyond the common variants of concern in the Spike protein analyzed by previous studies, we used a viral burden approach and detected a protective effect of low-frequency missense viral mutations in the RNA-dependent RNA polymerase (Pol) gene on disease severity. Our results contribute to the survey of severe COVID-19 in diverse populations and highlight the benefits of studying rare viral mutations.
Corruption in Nigeria–Removing the Psychological and Ethical Connections through Civic Education

: Corruption is pandemic in Nigeria. From high-profile cases to individual selfish mentality, the syndrome has been very pervasive and currently, corruption seems to be fighting back in the country. This paper highlights some definition of corruption and explores the psychological and ethical bases for corrupt mentality in Nigeria. The paper therefore posits that there is the need to institutionalize regulations with ethical reorientation of the young ones against greed and nepotism with appropriate civic value system. As charity begins at home, it is recommended that the home as an informal sector for civic learning should form a synergy with school civic education for promoting corrupt-free mentality.
Sheath effects on current collection by particle detectors with narrow acceptance angles

Restriction of the aperture acceptance angle of an ion or electron trap on an attracting spacecraft significantly alters the volt-ampere characteristics of the instrument in a low Mach number plasma. It is shown when the angular acceptance of the aperture is restricted the current to the collector tends to be independent of the Debye length. Expressions for the RPA characteristics for both a thin sheath and a thick sheath are derived; and it is shown that as the aperture is narrowed the curves tend toward equivalence.
Identiﬁcation before-after Forest Fire and Prediction of Mangrove Forest Based on Markov-Cellular Automata in Part of Sembilang National Park, Banyuasin, South Sumatra, Indonesia

: In 1997, the worst forest ﬁre in Indonesia occurred and hit mangrove forest areas including in Sembilang National Park Banyuasin Regency, South Sumatra. Therefore, the Indonesian government keeps in trying to rehabilitate the mangrove forest in Sembilang National Park. This study aimed to identify the mangrove forest changing and to predict on the future year. The situations before and after forest ﬁre were analyzed. This study applied an integrated Markov Chain and Cellular Automata model to identify mangrove forest change in the interval years of 1989–2015 and predict it in 2028. Remote sensing technology is used based on Landsat satellite imagery (1989, 1998, 2002, and 2015). The results showed mangrove forest has decreased around 9.6% from 1989 to 1998 due to forest ﬁre, and has increased by 8.4% between 1998 and 2002, and 2.3% in 2002–2015. Other results show that mangroves area has continued to increase from 2015 to 2028 by 27.4% to 31% (7974.8 ha). It shows that the mangrove ecosystem is periodically changing due to good management by the Indonesian government.
Wako UV Colorlmetrlc Pancreatic Lipase Assay wIth 1 , 2-Dlilnoieoylglycerol as Substrate Evaluated ,

Concentrations of laniinin, a main constituent of basement membranes, in serum are significantly increased in patients with chronic active liver disease, rheumatoid arthritis, tumors, and diabetes. We have now investigated laminin in sera ofhyperthyroid patients, because a report (1) noted increased concentrations of the aminoterminal propeptide oftype Ill procollagen (PIJINP), another connective-tissue-derived component, in serum of hyperthyroid patients. We determined laminin, triiodothyronine, thyroxin, free thyroxin (F#{149}F4), and thyrotropin (TSH) in sera from 42 patients with hyperthyroidism. Compared with a healthy reference population (n = 146, mean ± SD: 1.06 ± 0.15 kilo-arb. units/L), concentrations of laminin in serum of hyperthyroid patients (1.56 ± 0.33 kilo-arb. unitsfL) were significantly increased (P <0.01). Only weak correlations were found between laminin and VF (r = 0.32) and TSH (r = 0.50). The mean laminin concentration in serum of these patients is nearly the same as we have seen in patients with liver fibrosis (1.57 ± 0.47 kilo-arb. unitsfL), but is clearly lower than in patients with liver cirrhosis (2.16 ± 0.84 kilo-arb. units/L) (2). Increased laminin concentrations in hyperthyroidism might be caused directly by one or several of the thyroid hormones, but more probably the increase is a nonspecific consequence of the general metabolic activation in hyperthyroidism. For instance, we confirmed the finding (unpublished) that serum PIIINP is also significantly increased in patients suffering from hyperthyroidism (1). It is doubtful whether measurements of serum laminin are clinically useful for diagnosis and (or) follow-up of disorders of the thyroid gland. We saw no strong correlations between thyroid hormone concentrations and laminin, so the severity of the disease cannot be assessed by the degree of the increase of laminin in serum. However, our results clearly point to hyperthyroidism as an additional condition that must be considered when increased lainiin concentrations have to be interpreted.
Swarm based Optimization Technique for Detection of Brain Tumor in T2-Weighted MRI Images

Tumor detection is one of the most critical tasks from the brain MRI images. Commonly magnetic resonance scanner produces brain images with burst tissues where distinctive and combined sights of the tissues are required. The manual view of such tissues on image is impossible and leads to generate errors. Hence with the help of soft computing techniques, the detection of tumor region can be effectively done which will assist the radiologist extensively without errors. Several soft computing techniques have been proposed to improve the accuracy and reduce the false contour detection in medical images. In this work automatic brain tumor detection from MRI images using nature inspired meta-heuristic optimization technique is proposed. The proposed methodology consists of four stages such as pre-processing, segmentation, feature extraction and classification. In preprocessing, the quality of the image is enhanced with median filter by removing the noise. The particle swarm optimization (PSO) algorithm segments the pre-processed image and several textural and shape features are extracted through gray level co-occurrence matrix (GLCM) technique. Finally, the support vector machine (SVM) classifies the extracted tumor from the brain MRI images. The performance of the proposed automated detection method is evaluated on publically available dataset and real images and the obtained results are compared with existing methods. This method yields good, robust and fast segmentation results.

Eight highly expressed candidate genes were selected for mRNA proﬁling to monitor the transcriptome kinetics of Aspergillus fumigatus strains exposed to antifungal drugs as potential biomarkers of live cells to assess treatment efﬁcacy. Mycelia were treated with fungicidal drugs amphotericin B and voriconazole, as well as the fungistatic drug micafungin. Transcription was monitored at 0, 4, 8, and 24 h posttreatment. The expression turnover proﬁle provides a possible tool to assess antifungal therapy effects.
CESifo Working Paper Series CURRENCY TRADERS AND EXCHANGE RATE DYNAMICS: A SURVEY OF THE U.S. MARKET Yin-Wong

We report findings from a survey of United States foreign exchange traders. Our results indicate that: (i) in recent years electronically-brokered transactions have risen substantially, mostly at the expense of traditional brokers; (ii) the market norm is an important determinant of interbank bid-ask spread and the most widely-cited reason for deviating from the conventional bid-ask spread is a thin/hectic market; (iii) half or more of market respondents believe that large players dominate in the dollar-pound and dollar-Swiss franc markets; (iv) technical trading best characterizes about 30% of traders, with this proportion rising from five years ago; (v) news about macroeconomic variables is rapidly incorporated into exchange rates; (vi) the importance of individual macroeconomic variables shifts over time, although interest rates always appear to be important; (vii) economic fundamentals are perceived to be more important at longer horizons, while short-run deviations from the fundamentals are attributed to excess speculation and institutional customer/hedge fund manipulation; (viii) speculation is generally viewed positively, as enhancing market efficiency and liquidity, even though it exacerbates volatility; (ix) central bank intervention does not appear to have substantial effect, although there is general agreement that it increases volatility, and finally; (x) traders do not view purchasing power parity as a useful concept, even though a significant proportion (40%) believe that it affects exchange rates at horizons of over six months.
Review article Inclusion of jellyﬁsh in 30 þ years of Ecopath with Ecosim models

a decade ago concluded that recreation of jellyﬁsh population dynamics in models required additional ecological research and the careful consideration of their unique biology during model construction. Here, amidst calls for ecosystem-based management and the growing rec-ognition of jellyﬁshes’ role in foodwebs, we investigate how jellyﬁsh are implemented in EwE models and identify areas requiring improve-ment. Over time, an increasing percentage of models have included jellyﬁsh. Jellyﬁsh were often linked to the wider ecosystem, with many predators and prey included in models. However, ecotrophic efﬁciency, a measure of the extent to which they are used by higher trophic levels, was frequently set at low values, suggesting that jellyﬁsh are still perceived as under-utilized components of the ecosystem. Moving forward, greater care should be taken to differentiate the functional roles played by ctenophores, cnidarians, and pelagic tunicates. Additionally, when feasible, early life stages should be incorporated as multi-stanza groups to more accurately depict jellyﬁshes’ complex life cycle.
