Published: August 2023

Abstract
Purpose
Muscle contraction type in resistance exercise training may confer benefits besides strength in individuals with osteoarthritis and cardiovascular disease (CVD) risks. The purpose of the study was to explore whether Eccentric-resistance training (RT) improved hemodynamic responses to acute walking exercise stress compared to Concentric-RT among individuals with knee OA over four months.

Methods
This was a secondary analysis from a randomized, controlled, single-blinded study. Participants (N = 88; 68.3 ± 6.4 yrs; 67.4% female) were randomized to one of two work-matched resistance training (RT) programs against a non-RT control group. Pre-training and month four, participants completed a self-paced Six-Minute Walk Test (6MWT) and progressive treadmill exercise test. Heart rates, blood pressures and mean arterial pressures (MAP) were captured during each test. Antihypertensive medications use was documented at each time point.

Results
Leg strength improved in both training groups by month four (p < .05). Changes in 6MWT distance and progressive treadmill test time were not different across groups over four months. Neither Concentric or Eccentric RT produced different hemodyamic responses during the 6MWT compared to the control group post-training. However, Concentric RT was associated with 6.0%-7.4% reductions in systolic blood pressure during the graded treadmill walking test at 50%, 75% and 100% of the test time compared to Eccentric RT and the controls (p = .045). MAP values were lower at 75% and 100% of the treadmill test after Concentric RT (5.7%-6.0% reductions) compared to Eccentric RT (1.0%-2.4% reductions) and controls (1.5% and 4.0% elevations) post-training (p = .024). Antihypertensive medication use did not change in any group.

Conclusions
The repeated, progressive exposures of Concentric RT-induced blunted the hypertensive responses to acute exercise compared to Eccentric-RT. Among people with knee OA, Concentric-RT may confer strength benefits to manage OA and possibly reduce cardiovascular stress during exercise.

Abstract
Background
The evaluation of health status by cardiopulmonary exercise test (CPET) has shown increasing interest in the paediatric population. Our group recently established reference Z-score values for paediatric cycle ergometer VO2max, applicable to normal and extreme weights, from a cohort of 1141 healthy children. There are currently no validated reference values for the other CPET parameters in the paediatric population. This study aimed to establish, from the same cohort, reference Z-score values for the main paediatric cycle ergometer CPET parameters, apart from VO2max.

Results
In this cross-sectional study, 909 healthy children aged 5–18 years old underwent a CPET. Linear, quadratic, and polynomial mathematical regression equations were applied to identify the best CPET parameters Z-scores, according to anthropometric parameters (sex, age, height, weight, and BMI). This study provided Z-scores for maximal CPET parameters (heart rate, respiratory exchange ratio, workload, and oxygen pulse), submaximal CPET parameters (ventilatory anaerobic threshold, VE/VCO2 slope, and oxygen uptake efficiency slope), and maximum ventilatory CPET parameters (tidal volume, respiratory rate, breathing reserve, and ventilatory equivalent for CO2 and O2).

Conclusions
This study defined paediatric reference Z-score values for the main cycle ergometer CPET parameters, in addition to the existing reference values for VO2max, applicable to children of normal and extreme weights. Providing Z-scores for CPET parameters in the paediatric population should be useful in the follow-up of children with various chronic diseases. Thus, new paediatric research fields are opening up, such as prognostic studies and clinical trials using cardiopulmonary fitness outcomes.

Exploring bilingual EFL teacher resilience in the Iranian non-profit and state schools: a mixed-methods study
Authors: Rezazadeh Khadijeh , Janebi Enayat Mostafa , Poorebrahim Fatemeh 
Published: August 2023

AbstractThe present mixed-methods study investigated the factors that build Iranian bilingual Azeri-Persian English as a foreign language teacher resilience (TR) in non-profit and state schools. To do so, 205 male and female teachers selected through snowball sampling from several schools in different regions of Iran participated in this study. In the quantitative phase, the Connor and Davidson resilience scale (CD-RISC) was utilized to measure TR. First, the factor structure of the scale was ensured through testing confirmatory factor analysis (CFA). Results indicated that all the five factors of TR tested by the CD-RISC were evident among all the respondents, and there were no significant differences between the factors building TR in state and non-profit schools. For the qualitative phase, 26 male and female teachers selected through purposive sampling participated in semi-structured interviews which were thematically analyzed through MAXQDA software. The findings revealed that while state school teachers perceived satisfactory curriculum and policies and consulting with colleagues as the building factors for TR, non-profit school teachers highlighted teacher training courses, teacher-student rapport, and students’ progress as the important factors. The pedagogical implications of this study for teacher education are explained.

Published: August 2023

Abstract
Background
In patient-oriented research (POR), patients contribute their valuable knowledge and lived-experiences to work together as active research partners at all stages of the health research cycle. However, research looking to understand how patient research partners (PRPs) and researchers work together in meaningful and collaborative ways remains limited. This study aims to evaluate patient engagement with the RePORT Patient Advisory Council (PAC) and to identify barriers and facilitators to meaningful patient engagement encountered within research partnerships involving patient research partners and researchers.

Methods
The RePORT PAC members included nine PRPs and nine researchers (clinician-researchers, research staff, patient engagement experts) from both Alberta and British Columbia. All members were contacted and invited to complete an anonymous online survey (Public and Patient Engagement Evaluation (PPEET) tool) at two different project times points. The PAC was invited for a semi-structured interview to gain in-depth understanding of their experiences working together. Interviews were audio-recorded, transcribed, and the data was thematically analyzed with the support of a qualitative analysis software, NVivo.

Results
A total of nine PRPs (100%) and three researchers (33%) participated in the baseline survey in February 2022 while six PRPs (67%) responded and three researchers (33%) completed the follow up survey in May 2022. For the semi-structured interviews, nine PRPs (100%) and six researchers (67%) participated. According to the survey results, PAC members agreed that the supports (e. g. training, compensation) needed to contribute to the project were available throughout the project. The survey responses also showed that most members of the PAC felt their opinions and views were heard. Responses to the survey regarding diversity within the PAC were mixed. There were many suggestions for improving diversity and collaboration provided by PAC members during the semi-structured interviews. PAC members mentioned that PAC PRPs informed the co-development of research materials such as recruitment posters and interview guides for the RePORT study.

Conclusions
Through fostering a collaborative environment, we can engage a diverse group of people to work together meaningfully in health research. We have identified what works well, and areas for improvement within our research partnership involving PRPs and researchers as well as recommendations for POR projects more broadly, going forward.

Published: August 2023

Abstract
Background
This study aimed to analyze the clinical outcome and complications of narrow-diameter dental implants (NDIs) (diameter ≤3.5 mm).

Methods
The 274 NDIs that met the selection criteria from 2013 to 2018 were included in the retrospective study, and the survival rates (SVR) were compared. Mechanical complications included screw loosening and fractures of the implant components, such as the implant fixture, abutment, and prosthesis. In addition, marginal bone loss (MBL) was measured immediately after surgery and 1 year after loading.

Results
The 3-year cumulative SVR was 92.4%. Nineteen fixtures failed during the follow-up. The failure rate was significantly higher (OR=4.573, p<0.05) in smokers and was significantly higher in osteoporosis patients (OR=3.420, p<0.05). The vertical and horizontal values of MBL were 0.33±0.32 mm and 0.18±0.17 mm, respectively. Mechanical complications included screw loosening (5.5%) and porcelain fracture (2.2%), but no fractures of the fixture or components were observed. The choice of titanium and zirconium (TiZr) alloy implant was significantly more frequent in the posterior region. Bone graft was significantly more frequently done in the anterior region.

Conclusions
According to the high SVR and stability of NDIs, the findings of the study suggest that NDIs may be a replacement for regular diameter dental implants (RDIs) and the use of TiZr alloy could extend the indication of NDIs. In the esthetic area, contour augmentation may be a reason for increasing the frequency of bone grafts.
Traditional food for a sustainable future? exploring vulnerabilities and strengths in Italy’s foodscape and short agrifood chains
Authors: Fontefrancesco Michele Filippo 
Published: August 2023

AbstractThe article discusses the role of gastronomy in shaping a sustainable future and highlights the importance of food as a fundamental resource for sustainable development. It emphasizes the need to reevaluate food production, sales, and consumption cycles to minimize their economic, environmental, and social impact on the planet. The concept of sustainability has evolved beyond its initial definition and now focuses on rejuvenating compromised environments. The critique of 20th-century food production methods and the cultural dominance of maximizing yields and standardizing production is mentioned. The text also mentions the resurgence of interest in local and indigenous gastronomies and the potential risks of oversimplification and underestimation in valuing these culinary traditions. The vulnerabilities and strengths of short agrifood chains in Italy are analyzed, and the article suggests ways forward for utilizing traditional gastronomy for economic and rural development. The analysis is part of the “NODES- Nord Ovest Digitale e Sostenibile” project funded by the Italian Ministry of University and Research.
Enhancing non-profiled side-channel attacks by time-frequency analysis
Authors: Jin Chengbin , Zhou Yongbin 
Published: August 2023

AbstractSide-channel analysis (SCA) has become an increasing important method to assess the physical security of cryptographic systems. In the process of SCA, the number of attack data directly determines the performance of SCA. With sufficient attack data, the adversary can achieve a successful SCA. However, in reality, the cryptographic device may be protected with some countermeasures to limit the number of encryptions using the same key. In this case, the adversary cannot use casual numbers of data to perform SCA. The performance of SCA will be severely dropped if the attack traces are insufficient. In this paper, we introduce wavelet scatter transform (WST) and short-time fourier transform (STFT) to non-profiled side-channel analysis domains, to improve the performance of side-channel attacks in the context of insufficient data. We design a practical framework to provide suitable parameters for WST/STFT-based SCA. Using the proposed method, the WST/STFT-based SCA method can significantly enhance the performance and robustness of non-profiled SCA. The practical attacks against four public datasets show that the proposed method is able to achieve more robust performance. Compared with the original correlation power analysis (CPA), the number of attack data can be reduced by 50–95%.

Published: August 2023

AbstractPrediction and diagnosis of cardiovascular diseases (CVDs) based, among other things, on medical examinations and patient symptoms are the biggest challenges in medicine. About 17.9 million people die from CVDs annually, accounting for 31% of all deaths worldwide. With a timely prognosis and thorough consideration of the patient’s medical history and lifestyle, it is possible to predict CVDs and take preventive measures to eliminate or control this life-threatening disease. In this study, we used various patient datasets from a major hospital in the United States as prognostic factors for CVD. The data was obtained by monitoring a total of 918 patients whose criteria for adults were 28-77 years old. In this study, we present a data mining modeling approach to analyze the performance, classification accuracy and number of clusters on Cardiovascular Disease Prognostic datasets in unsupervised machine learning (ML) using the Orange data mining software. Various techniques are then used to classify the model parameters, such as k-nearest neighbors, support vector machine, random forest, artificial neural network (ANN), naïve bayes, logistic regression, stochastic gradient descent (SGD), and AdaBoost. To determine the number of clusters, various unsupervised ML clustering methods were used, such as k-means, hierarchical, and density-based spatial clustering of applications with noise clustering. The results showed that the best model performance analysis and classification accuracy were SGD and ANN, both of which had a high score of 0.900 on Cardiovascular Disease Prognostic datasets. Based on the results of most clustering methods, such as k-means and hierarchical clustering, Cardiovascular Disease Prognostic datasets can be divided into two clusters. The prognostic accuracy of CVD depends on the accuracy of the proposed model in determining the diagnostic model. The more accurate the model, the better it can predict which patients are at risk for CVD.
Performance and control of a reverse osmosis unit integrated with Pelton Wheel to supply emergency electric loads under various operating conditions

Published: August 2023

AbstractNowadays, the whole world is moving very quickly into the field of seawater desalination. This is because the world suffers from a lack of potable water. Water and energy are adjoining linked fields. The present work aims at investigating the performance of a reverse osmosis (RO) plant integrated with Pelton Wheel under various operating conditions. The main reason for using Pelton turbine instead of the pressure exchanger (PX) is the low cost of Pelton compared to that of PX. The RO system integrated with the Pelton Wheel was tested under various operating pressures of 650, 700, 750, 800, and 850 kPa. Changing the feed water pressure affects the pressure of the reject entering the Pelton wheel and this, in turn, affects the velocity of the water jet. Also, the impact of varying the feed water salinity (total dissolved solids (TDS) = 400, 500, 600, 700, and 850 ppm) and temperature (20–39 °C) on the permeate and reject of RO was tested. In addition, a theoretical modeling was built to predict the performance of the RO system. The permeate flow rate was increased by raising the RO operating pressures. The permeate flow rate was augmented from 2.5 to 4.3 L min−1 when increasing the operating pressure from 650 to 850 kPa, respectively. Therefore, the permeate flow rate is enhanced by around 72% when increasing the operating pressure by only 30%. Besides, increasing the pressure by 30% (from 650 to 860 kPa) decreased the generated power of the Pelton Wheel by approximately 72% (from 960 to 270 W, respectively). Also, increasing the feed water salinity leads to raise the salinity of RO permeate, and vice versa. The RO permeate salinity is raised from 165 to 285 ppm when increasing the operating pressure from 650 to 850 kPa, respectively. As well, the more the increase in feed water temperature, the more improve in the permeate flux and salinity. The permeate TDS was decreased from 140 ppm at feed-water temperature 20 °C to 56 ppm at feed water temperature 39 °C. In this study, the Arduino program circuit was used to supply the required emergency loads by controlling the pressure values of high-pressure pump due to easy and open code program. Finally, the theoretical modelling results are in good correspondence with the experimental results. The average deviation among the theoretical and experimental results was 3.5%.

Background
Prior self-harm represents the most significant risk factor for future self-harm or suicide.

Aim
To evaluate the cost-effectiveness of a theoretical brief aftercare intervention (involving brief follow-up contact, care coordination and safety planning), following a hospital-treated self-harm episode, for reducing repeated self-harm within the Australian context.

Method
We employed economic modelling techniques to undertake: (a) a return-on-investment analysis, which compared the cost-savings generated by the intervention with the overall cost of implementing the intervention; and (b) a cost–utility analysis, which compared the net costs of the intervention with health outcomes measured in quality-adjusted life years (QALYs). We considered cost offsets associated with hospital admission for self-harm and the cost of suicide over a period of 10 years in the base case analysis. Uncertainty and one-way sensitivity analyses were also conducted.

Results
The brief aftercare intervention resulted in net cost-savings of AUD$7.5 M (95% uncertainty interval: −56.2 M to 15.1 M) and was associated with a gain of 222 (95% uncertainty interval: 45 to 563) QALYs over a 10-year period. The estimated return-on-investment ratio for the intervention's modelled cost in relation to cost-savings was 1.58 (95% uncertainty interval: −0.17 to 5.33). Eighty-seven per cent of uncertainty iterations showed that the intervention could be considered cost-effective, either through cost-savings or with an acceptable cost-effectiveness ratio of 50 000 per QALY gained. The results remained robust across sensitivity analyses.

Conclusions
A theoretical brief aftercare intervention is highly likely to be cost-effective for preventing suicide and self-harm among individuals with a history of self-harm.

Aspects of Significance in the “Dark Heritage” of Thessaloniki, Greece
Authors: Zygomalas Dimitrios 
Published: August 2023

Located in the north of Greece and boasting an interrupted history of over 2.300 years, Thessaloniki has a wide array of architectural monuments to display. Hellenistic residences, Roman administrative centers, Byzantine churches, and Ottoman communal buildings have shaped for decades the city’s historical profile, leaving limited space for a nonetheless widely acknowledged architectural grouping, namely its “dark heritage”.
Comprising buildings and sites that have over the years been related to rare phenomena and curious events, Thessaloniki’s “heritage of darkness” fascinates the imagination of its residents, in addition to providing a frequent subject for the writings of local journalists and researchers, and a focal point in the work of the services and bodies involved in monument protection. The above players evidently evaluate its constituents in different manners, thus leading to the emergence of multiple aspects of significance in the appraisal of the city’s “dark heritage”.
This paper aims to identify these aspects and determine their interrelation and impact on the preservation of the buildings and sites involved. To this end, based on bibliographical research and on-site examination, it begins with a comprehensive overview of the dreaded built assets, followed by the identification of the players involved in their treatment and their respective attitudes. From there on, a discussion of the interaction of these attitudes is pursued, culminating in original conclusions as to the consequences of this interaction for the safeguarding of the tangible and intangible qualities of the city’s “heritage of the dark”.

Authors: Ramanathan Malinidevi , Kalirajan Vaishnavi 
Published: August 2023

In this paper, the Maize Streak Virus disease model which involves the Maize and the Homopteran population is considered. This system of the differential equation is analytically solved by using Adomian Decomposition Method. The analytical results are compared with numerical simulation by assuming certain values for the parameter. Further, the demolishing and contamination rate of contagious and receptive homopteran on receptive and contagious Maize plant parameters are analyzed to reduce the contamination rate. In addition, the death rates of contagious maize, receptive homopteran and contagious homopteran are also discussed to remove the contagious population and make them free from Maize Streak Virus.
