Method: A controlled and randomized study, blind to the evaluator, was executed. We evaluated 78 elderly people, divided into the neuropsychological and control groups, through a semi-structured interview, Addenbrooke’s Cognitive Examination, Katz Index, Lawton and Brody Scale, Geriatric Depression Scale, Beck Anxiety Inventory, Personal Development Scale, WHOQOL-bref and WHOQOL--old. Results: After the intervention, the neuropsychological group showed improvement in the cognitive subtests and in the total score, reduction in the frequency of symptoms associated with anxiety and depression, better psychological well-being, and quality of life. The research highlights useful intervention strategies for improving the general condition of these patients and rehabilitating damaged areas. Conclusion: We concluded that there is a relationship between neuropsychological intervention and improvement in cognitive and psychological performance, as well as in the quality of life in elderly people with mild cognitive impairment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aging" title="aging">aging</a>, <a href="https://publications.waset.org/abstracts/search?q=mild%20cognitive%20impairment" title=" mild cognitive impairment"> mild cognitive impairment</a>, <a href="https://publications.waset.org/abstracts/search?q=neuropsychology" title=" neuropsychology"> neuropsychology</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/152754/impact-of-neuropsychological-intervention-in-mild-cognitive-impairment-a-controlled-randomized-and-blind-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152754.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">174</span> Histological Characteristics of the Organs of Adult Zebrafish as a Biomarker for the Study of New Drugs with Effect on the Snake Venom of Bothrops alternatus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Carlos%20Tavares%20Carvalho">Jose Carlos Tavares Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hady%20Keita"> Hady Keita</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Rocha%20Santana"> Giovanna Rocha Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Victor%20Ferreira%20Dos%20Santos"> Igor Victor Ferreira Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesus%20Rafael%20Rodriguez%20Amado"> Jesus Rafael Rodriguez Amado</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariadna%20Lafourcade%20Prada"> Ariadna Lafourcade Prada</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Maciel%20Ferreira"> Adriana Maciel Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Helison%20Oliveira"> Helison Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Summary: As animal model, zebrafish can be a good opportunity to establish a profile of tissue alteration caused by Bothrops alternatus venom and to screen new anti-venom drugs. Objective: To establish tissue biomarkers from zebrafish injected by snake venom and elucidate the use of glucocorticoids in ophidic accidents. Materials and Methods: The Danio rerio fish were randomly divided into four groups: control group, venom group, Dexamethasone1h before venom injected group and Dexamethasone 1 h after venom injected group. The concentration of Bothrops alternatus venom was 0.13 mg/ml and the fish received 20µl/Fish. The Body weight measurement and histological characteristics of gills, kidneys, liver, and intestine were determinate. Results: Physical analysis shows necrosis accompanied by inflammation in animals receiving the Bothrops alternatus venom. Significant difference was observed in the variation of weight between the control group, and the groups received the venom (t student test, p < 0.05). The average histological alterations index of gill, liver, kidney or intestine was statistically higher in animals received the venom (t Student test, p < 0.05). The alterations were lower in the groups that received Dexamethasone 1h before and after venom injected compared to the group that received only the venom. Dexamethasone 1h before venom injected group had minor histopathological alterations. Conclusion: The organs of zebrafish may be a tissue biomarker of alterations from Bothrops alternatus venom and dexamethasone reduced the damage caused by this venom in the organs studied, which may suggest the use of zebrafish as animal model for research related to screening new drug against snake venom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zebrafish" title="zebrafish">zebrafish</a>, <a href="https://publications.waset.org/abstracts/search?q=snake%20venom" title=" snake venom"> snake venom</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=drugs" title=" drugs"> drugs</a> </p> <a href="https://publications.waset.org/abstracts/53757/histological-characteristics-of-the-organs-of-adult-zebrafish-as-a-biomarker-for-the-study-of-new-drugs-with-effect-on-the-snake-venom-of-bothrops-alternatus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53757.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">173</span> Assessment of Students Skills in Error Detection in SQL Classes using Rubric Framework - An Empirical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dirson%20Santos%20De%20Campos">Dirson Santos De Campos</a>, <a href="https://publications.waset.org/abstracts/search?q=Deller%20James%20Ferreira"> Deller James Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Cavalcante%20Gon%C3%A7alves"> Anderson Cavalcante Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Uyara%20Ferreira%20Silva"> Uyara Ferreira Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rubrics to learning research provide many evaluation criteria and expected performance standards linked to defined student activity for learning and pedagogical objectives. Despite the rubric being used in education at all levels, academic literature on rubrics as a tool to support research in SQL Education is quite rare. There is a large class of SQL queries is syntactically correct, but certainly, not all are semantically correct. Detecting and correcting errors is a recurring problem in SQL education. In this paper, we usthe Rubric Abstract Framework (RAF), which consists of steps, that allows us to map the information to measure student performance guided by didactic objectives defined by the teacher as long as it is contextualized domain modeling by rubric. An empirical study was done that demonstrates how rubrics can mitigate student difficulties in finding logical errors and easing teacher workload in SQL education. Detecting and correcting logical errors is an important skill for students. Researchers have proposed several ways to improve SQL education because understanding this paradigm skills are crucial in software engineering and computer science. The RAF instantiation was using in an empirical study developed during the COVID-19 pandemic in database course. The pandemic transformed face-to-face and remote education, without presential classes. The lab activities were conducted remotely, which hinders the teaching-learning process, in particular for this research, in verifying the evidence or statements of knowledge, skills, and abilities (KSAs) of students. Various research in academia and industry involved databases. The innovation proposed in this paper is the approach used where the results obtained when using rubrics to map logical errors in query formulation have been analyzed with gains obtained by students empirically verified. The research approach can be used in the post-pandemic period in both classroom and distance learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rubric" title="rubric">rubric</a>, <a href="https://publications.waset.org/abstracts/search?q=logical%20error" title=" logical error"> logical error</a>, <a href="https://publications.waset.org/abstracts/search?q=structured%20query%20language%20%28SQL%29" title=" structured query language (SQL)"> structured query language (SQL)</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20study" title=" empirical study"> empirical study</a>, <a href="https://publications.waset.org/abstracts/search?q=SQL%20education" title=" SQL education"> SQL education</a> </p> <a href="https://publications.waset.org/abstracts/142000/assessment-of-students-skills-in-error-detection-in-sql-classes-using-rubric-framework-an-empirical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142000.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">172</span> A Model for Operating Rooms Scheduling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Francisco%20Ferreira%20Ribeiro">Jose Francisco Ferreira Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Bevilacqua%20Leoneti"> Alexandre Bevilacqua Leoneti</a>, <a href="https://publications.waset.org/abstracts/search?q=Andre%20Lucirton%20Costa"> Andre Lucirton Costa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a mathematical model in binary variables 0/1 to make the assignment of surgical procedures to the operating rooms in a hospital.

Bystanders of this phenomenon can help diminish the incidence of this phenomenon if they engage in pro-social behavior. However, different social-cognitive and affective bystander reactions may surface because of the lack of contextual information and emotional cues in cyberbullying situations. Hence, this study investigated how cyberbullying bystanders’ unpleasant emotions could be related to their personal moral beliefs and their behavioral intentions to cyberbully or defend the victim. It also proposed to investigate how their normative beliefs of perceived severity about cyberbullying behavior could be related to their personal moral beliefs and their behavioral intentions. Three groups of adolescents participated in this study, namely a first of group 402 students (5th – 12th graders; Mage = 13.12; SD = 2.19; 55.7% girls) to compute explorative factorial analyses of the instruments used; a second group of 676 students (5th – 12th graders; Mage = 14.10; SD = 2.74; 55.5% were boys) to run confirmatory factor analyses; and a third group (N = 397; 5th – 12th graders; Mage = 13.88 years; SD = 1.45; 55.5% girls) to perform the main analyses to test the research hypotheses. Self-report measures were used, such as the Personal moral beliefs about cyberbullying behavior questionnaire, the Normative beliefs of perceived severity about cyberbullying behavior questionnaire, the Unpleasant emotions about cyberbullying incidents questionnaires, and the Bystanders’ behavioral intentions in cyberbullying situations questionnaires. Path analysis results revealed that unpleasant emotions were mediators of the relationship between adolescent cyberbullying bystanders’ personal moral beliefs and their intentions to help the victims in cyberbullying situations. Moreover, adolescent cyberbullying bystanders’ normative beliefs of gravity were mediators of the relationship between their personal moral beliefs and their intentions to cyberbully others. These findings provide insights for the development of prevention and intervention programs that promote social and emotional learning strategies as a means to prevent and intervene in cyberbullying. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyberbullying" title="cyberbullying">cyberbullying</a>, <a href="https://publications.waset.org/abstracts/search?q=normative%20beliefs%20of%20perceived%20severity" title=" normative beliefs of perceived severity"> normative beliefs of perceived severity</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20moral%20beliefs" title=" personal moral beliefs"> personal moral beliefs</a>, <a href="https://publications.waset.org/abstracts/search?q=unpleasant%20emotions" title=" unpleasant emotions"> unpleasant emotions</a> </p> <a href="https://publications.waset.org/abstracts/142308/how-unpleasant-emotions-morals-and-normative-beliefs-of-severity-relate-to-cyberbullying-intentions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142308.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">217</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">170</span> Program of Health/Safety Integration and the Total Worker Health Concept in the Improvement of Absenteeism of the Work Accommodation Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20R.%20Ferreira">L.

Work accommodation is a necessity in most companies as it allows the worker to return to its function respecting its physical limitations. This study had the objective to verify if the integration of health and safety in the companies, with the inclusion of the concept of TWH promoted by an occupational health service has impacted in the management of absenteeism of workers in work accommodation. Method: A retrospective and paired cohort study was used, in which the impact of the implementation of the Program for the Health/Safety Integration and Total Worker Health Concept (PHSITWHC) was evaluated using the indices of absenteeism, health attestations, days and hours of sick leave of workers that underwent job accommodation/rehabilitation. This was a cohort study and the data were collected from January to September of 2017, prior to the initiation of the integration program, and compared with the data obtained from January to September of 2018, after the implementation of the program. For the statistical analysis, the student's t-test was used, with statistically significant differences being made at p < 0.05. Results: The results showed a 35% reduction in the number of absenteeism rate in 2018 compared to the same period in 2017. There was also a significant reduction in the total numbers of days of attestations/absences (mean of 2,8) as well as days of attestations, absence and sick leaves (mean of 5,2) in 2018 data after the implementation of PHSITWHC compared to 2017 data, means of 4,3 and 25,1, respectively, prior to the program. Conclusion: It can be concluded that the inclusion of the PHSITWHC was associated with a reduction in the rate of absenteeism of workers that underwent job accommodation. It was observed that, once health and safety were approached and integrated with the inclusion of the TWH concept, it was possible to reduce absenteeism, and improve worker’s quality of life and wellness, and work accommodation management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absenteeism" title="absenteeism">absenteeism</a>, <a href="https://publications.waset.org/abstracts/search?q=health%2Fsafety%20integration" title=" health/safety integration"> health/safety integration</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20accommodation%20management" title=" work accommodation management"> work accommodation management</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20worker%20health" title=" total worker health"> total worker health</a> </p> <a href="https://publications.waset.org/abstracts/105106/program-of-healthsafety-integration-and-the-total-worker-health-concept-in-the-improvement-of-absenteeism-of-the-work-accommodation-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">169</span> Computational Tool for Surface Electromyography Analysis; an Easy Way for Non-Engineers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabiano%20Araujo%20Soares">Fabiano Araujo Soares</a>, <a href="https://publications.waset.org/abstracts/search?q=Sauro%20Emerick%20Salomoni"> Sauro Emerick Salomoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Paulo%20Lima%20da%20Silva"> Joao Paulo Lima da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Luiz%20Moura"> Igor Luiz Moura</a>, <a href="https://publications.waset.org/abstracts/search?q=Adson%20Ferreira%20da%20Rocha"> Adson Ferreira da Rocha </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a tool developed in the Matlab platform.

The study analyzed the association between the worker’s health and the actions performed by the companies related to injured professional. The research method performed a retrospective, cross-sectional and quantitative database analysis. The documents of labor lawsuits with shoulder injury registered at the Regional Labor Court in the 15<sup>th</sup> region (Campinas - São Paulo) were submitted to the medical examination and evaluated during the period from 2012 until 2015. The data collected were age, gender, onset of symptoms, length of service, current occupation, type of shoulder injury, referred complaints, type of acromion, associated or related diseases, company actions as CAT (workplace accident communication), compliance of NR7 by the organization (Environmental Risk Prevention Program - PPRA and Medical Coordination Program in Occupational Health - PCMSO). Results: From the 93 workers evaluated, there was a prevalence of men (58.1%), with a mean age of 42.6 y-o, and 54.8% were included in the age group 35-49 years. Regarding the length of work time in the company, 66.7% have worked for more than 5 years. There was an association between gender and current occupational status (p < 0.005), with predominance of women in household occupation (13 vs. 2) and predominance of unemployed men in job search situation (24 vs. 10) and reintegrated to work by judicial decision (8 vs. 2). There was also a correlation between pain and functional limitation (p < 0.01). There was a positive association of PPRA with the complaint of functional limitation and negative association with pain (p < 0.04). There was also a correlation between the sedentary lifestyle and the presence of PCMSO and PPRA (p < 0.04), and the absence of CAT in the companies (p < 0.001). It was concluded that the appearance or aggravation of osseous and articular shoulder pathologies in workers who have undertaken labor law suits seem to be associated with individual habits or inadequate labor practices. These data can help preventing the occurrence of these lesions by implementing local health promotion policies at work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=work-related%20accidents" title="work-related accidents">work-related accidents</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-sectional%20study" title=" cross-sectional study"> cross-sectional study</a>, <a href="https://publications.waset.org/abstracts/search?q=shoulder%20lesions" title=" shoulder lesions"> shoulder lesions</a>, <a href="https://publications.waset.org/abstracts/search?q=labor%20lawsuits" title=" labor lawsuits"> labor lawsuits</a> </p> <a href="https://publications.waset.org/abstracts/105103/work-related-shoulder-lesions-and-labor-lawsuits-in-brazil-cross-sectional-study-on-worker-health-actions-developed-by-employers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105103.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">218</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">167</span> Adsorption of Paracetamol Using Activated Carbon of Dende and Babassu Coconut Mesocarp</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20C.%20Ferreira">R.

Kinetic and equilibrium data were obtained at different values of pH. Babassu activated carbon showed higher efficiency due to its acidity and higher microporosity. Pseudo-second order model was better adjusted to the kinetic results. Equilibrium data may be represented by Langmuir equation. Lower solution pH provided better removal efficiency as the carbonil groups may be attracted by the positively charged carbon surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title=" activated carbon"> activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=babassu" title=" babassu"> babassu</a>, <a href="https://publications.waset.org/abstracts/search?q=dende" title=" dende"> dende</a> </p> <a href="https://publications.waset.org/abstracts/23917/adsorption-of-paracetamol-using-activated-carbon-of-dende-and-babassu-coconut-mesocarp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23917.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">166</span> Biostimulation Effect of Ozone Therapy and Superficial Peeling on Facial Rejuvenation: A Case Report and Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferreira%20R.">Ferreira R.</a>, <a href="https://publications.waset.org/abstracts/search?q=Rocha%20K."> Rocha K.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ozone therapy is indicated for improving skin aesthetics, adjusting oxidative tissue levels, increasing collagen production, and even skin volumizing.

For this, the methodology used was based on a statistical analysis of the data provided by the Government of Spain. The results will allow to know in which jobs women suffer accidents, in what type of companies and the severity of the accident. Based on these results, specific intervention policies may be defined according to the needs detected in each sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Injured%20women" title="Injured women">Injured women</a>, <a href="https://publications.waset.org/abstracts/search?q=Gender%20perspective" title=" Gender perspective"> Gender perspective</a>, <a href="https://publications.waset.org/abstracts/search?q=Occupational%20accidents" title=" Occupational accidents"> Occupational accidents</a>, <a href="https://publications.waset.org/abstracts/search?q=Occupational%20health%20and%20safety" title=" Occupational health and safety"> Occupational health and safety</a> </p> <a href="https://publications.waset.org/abstracts/124124/the-gender-perspective-applied-to-the-analysis-of-occupational-accidents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124124.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">164</span> Photoluminescence Spectroscopy to Probe Mixed Valence State in Eu-Doped Nanocrystalline Glass-Ceramics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruchika%20Bagga">Ruchika Bagga</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauro%20Falconieri"> Mauro Falconieri</a>, <a href="https://publications.waset.org/abstracts/search?q=Venu%20Gopal%20Achanta"> Venu Gopal Achanta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20M.%20F.%20Ferreira"> José M.

Consequently, the nature and essence of the workplace needs to be reconfigured so that creativity and productivity can be better promoted at these spaces. Using a multidisciplinary approach and a user-centered methodology, combining product design, electronic engineering, software and human-computer interaction, we have designed and developed a new seat that uses embedded sensors and actuators to increase the overall well-being of its users, their productivity and their creativity. Our contribution focuses on the parameters that most affect the user’s work on these kinds of spaces, which are, according to our study, noise and temperature.

This study seeks to develop a conceptual model aimed at measuring the dynamic interactions of the triple/quadruple helix, balancing innovation and entrepreneurship initiatives as pillars of regional competitiveness – the Regional Helix Scoreboard (RHS). To this aim, different strands of literature are identified according to their focus on specific regional competitiveness governance mechanisms. We put forward an overview of the state-of-the-art of research and is duly assessed in order to develop and propose a framework of analysis that enables an integrated approach in the context of collaborative dynamics. We conclude by presenting the RHS for the study of regional competitiveness dynamics, which integrates and associates different backgrounds and identifies a number of key performance indicators for research challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=KPIs" title=" KPIs"> KPIs</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20measurement" title=" performance measurement"> performance measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20competitiveness" title=" regional competitiveness"> regional competitiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20helix%20scoreboard" title=" regional helix scoreboard"> regional helix scoreboard</a> </p> <a href="https://publications.waset.org/abstracts/51803/measuring-innovative-and-entrepreneurial-networks-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51803.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">329</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">159</span> Relation of Electromyography, Strength and Fatigue During Ramp Isometric Contractions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Ferreira%20Amorim">Cesar Ferreira Amorim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamotsu%20Hirata"> Tamotsu Hirata</a>, <a href="https://publications.waset.org/abstracts/search?q=Runer%20Augusto%20Marson"> Runer Augusto Marson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to determine the effect of strength ramp isometric contraction on changes in surface electromyography (sEMG) signal characteristics of the hamstrings muscles. All measurements were obtained from 20 healthy well trained healthy adults (age 19.5 ± 0.8 yrs, body mass 63.4 ± 1.5 kg, height: 1.65 ± 0.05 m). Subjects had to perform isometric ramp contractions in knee flexion with the force gradually increasing from 0 to 40% of the maximal voluntary contraction (MVC) in a 20s period. The root mean square (RMS) amplitude of sEMG signals obtained from the biceps femoris (caput longum) were calculated at four different strength levels (10, 20, 30, and 40% MVC) from the ramp isometric contractions (5s during the 20s task %MVC). The main results were a more pronounced increase non-linear in sEMG-RMS amplitude for the muscles. The protocol described here may provide a useful index for measuring of strength neuromuscular fatigue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosignal" title="biosignal">biosignal</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20electromyography" title=" surface electromyography"> surface electromyography</a>, <a href="https://publications.waset.org/abstracts/search?q=ramp%20contractions" title=" ramp contractions"> ramp contractions</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/32275/relation-of-electromyography-strength-and-fatigue-during-ramp-isometric-contractions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32275.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">483</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">158</span> Creating a Virtual Perception for Upper Limb Rehabilitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nina%20Robson">Nina Robson</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenneth%20John%20Faller%20II"> Kenneth John Faller II</a>, <a href="https://publications.waset.org/abstracts/search?q=Vishalkumar%20Ahir"> Vishalkumar Ahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Arthur%20Ricardo%20Deps%20Miguel%20Ferreira"> Arthur Ricardo Deps Miguel Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Buchanan"> John Buchanan</a>, <a href="https://publications.waset.org/abstracts/search?q=Amarnath%20Banerjee"> Amarnath Banerjee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the development of a virtual-reality system ARWED, which will be used in physical rehabilitation of patients with reduced upper extremity mobility to increase limb Active Range of Motion (AROM).

The removal is very expensive due to the high cost of normal adsorbents. Lignocellulosic materials and mainly treated materials have proven to be a good solution for this problem. Adsorption tests were performed at different pH, different times and with varying concentrations. Results show that is at pH 3 that treated wood absorbs more chromium ranging from 70% (2h treatment) to almost 100% (12 h treatment) much more than untreated wood with less than 40%. Most of the adsorption is made in the first 2-3 hours for untreated and heat treated wood. Modified wood adsorbs more chromium throughout the time. For all the samples, adsorption fitted relatively well the Langmuir model with correlation coefficient ranging from 0.85 to 0.97. The results show that heat treated wood is a good adsorbent ant that this might be a good utilization for sawdust from treating companies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium" title=" chromium"> chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20modification" title=" wood modification"> wood modification</a> </p> <a href="https://publications.waset.org/abstracts/11132/chromium-adsorption-by-modified-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11132.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">499</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">156</span> Machine Learning Techniques to Develop Traffic Accident Frequency Prediction Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Aguiar">Rodrigo Aguiar</a>, <a href="https://publications.waset.org/abstracts/search?q=Adelino%20Ferreira"> Adelino Ferreira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Road traffic accidents are the leading cause of unnatural death and injuries worldwide, representing a significant problem of road safety.

Method: Clinical, crossover study, in which six adult individuals diagnosed with MS and spasticity in the lower limbs were randomized to receive one session of high-frequency (≥5Hz) and low-frequency (≤ 1Hz) TMS on motor cortex (M1) hotspot for quadriceps muscle, with a one-week interval between the sessions. To assess the spasticity was applied the Ashworth scale and were analyzed the latency time (ms) of the motor evoked potential (MEP) and the central motor conduction time (CMCT) of the bilateral quadriceps muscle. Assessments were performed before and after each intervention. The difference between groups was analyzed using the Friedman test, with a significance level of 0.05 adopted. Results: All statistical analyzes were performed using the SPSS Statistic version 26 programs, with a significance level established for the analyzes at p<0.05. Shapiro Wilk normality test. Parametric data were represented as mean and standard deviation for non-parametric variables, median and interquartile range, and frequency and percentage for categorical variables. There was no clinical change in quadriceps spasticity assessed using the Ashworth scale for the 1 Hz (p=0.813) and 5 Hz (p= 0.232) protocols for both limbs. Motor Evoked Potential latency time: in the 5hz protocol, there was no significant change for the contralateral side from pre to post-treatment (p>0.05), and for the ipsilateral side, there was a decrease in latency time of 0.07 seconds (p<0.05 ); for the 1Hz protocol there was an increase of 0.04 seconds in the latency time (p<0.05) for the contralateral side to the stimulus, and for the ipsilateral side there was a decrease in the latency time of 0.04 seconds (p=<0.05), with a significant difference between the contralateral (p=0.007) and ipsilateral (p=0.014) groups. Central motor conduction time in the 1Hz protocol, there was no change for the contralateral side (p>0.05) and for the ipsilateral side (p>0.05). In the 5Hz protocol for the contralateral side, there was a small decrease in latency time (p<0.05) and for the ipsilateral side, there was a decrease of 0.6 seconds in the latency time (p<0.05) with a significant difference between groups (p=0.019). Conclusion: A high or low-frequency session does not change spasticity, but it is observed that when the low-frequency protocol was performed, there was an increase in latency time on the stimulated side, and a decrease in latency time on the non-stimulated side, considering then that inhibiting the motor cortex increases cortical excitability on the opposite side. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title="multiple sclerosis">multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=spasticity" title=" spasticity"> spasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20evoked%20potential" title=" motor evoked potential"> motor evoked potential</a>, <a href="https://publications.waset.org/abstracts/search?q=transcranial%20magnetic%20stimulation" title=" transcranial magnetic stimulation"> transcranial magnetic stimulation</a> </p> <a href="https://publications.waset.org/abstracts/165786/comparison-of-two-transcranial-magnetic-stimulation-protocols-on-spasticity-in-multiple-sclerosis-pilot-study-of-a-randomized-and-blind-cross-over-clinical-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165786.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">154</span> Cerium Salt Effect in 70s Bioactive Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandra%20N.%20Santos">Alessandra N.

After hydrothermal and cation exchange procedures, the Mn residues transformed to a single phase, Mg-OMS-1. The raw material and the synthesis processes were analyzed by means of X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Infrared spectroscopy (FTIR). The tunnel structure was synthesized hydrothermally at 180 °C for three days without impurities. According to the XRD analysis, the formation of crystalline Mg-OMS-1 was identified through reflections at 9.8º, 12º and 18º (2θ), as well as a thermal stability around 300 ºC. The SEM analysis indicated that the final product presents good crystallinity with a homogeneous size. In addition, an intense and diagnostic FTIR band was identified at 515 cm⁻¹ related to the MnO₆ octahedral stretching vibrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mn%20residues" title="Mn residues ">Mn residues </a>, <a href="https://publications.waset.org/abstracts/search?q=Octahedral%20Molecular%20Sieve" title=" Octahedral Molecular Sieve"> Octahedral Molecular Sieve</a>, <a href="https://publications.waset.org/abstracts/search?q=Synthesis" title=" Synthesis"> Synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=Characterization" title=" Characterization"> Characterization</a> </p> <a href="https://publications.waset.org/abstracts/76558/hydrothermal-synthesis-of-octahedral-molecular-sieve-from-mn-oxide-residues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76558.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">192</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">151</span> An Electromechanical Device to Use in Road Pavements to Convert Vehicles Mechanical Energy into Electrical Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Duarte">Francisco Duarte</a>, <a href="https://publications.waset.org/abstracts/search?q=Adelino%20Ferreira"> Adelino Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Fael"> Paulo Fael</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the growing need for alternative energy sources, research into energy harvesting technologies has increased considerably in recent years. The particular case of energy harvesting on road pavements is a very recent area of research, with different technologies having been developed in recent years.

This paper deals with the development of a mechanical system to implement on a road pavement energy harvesting electromechanical device, to transmit energy from the device surface to an electrical generator. The main goal is to quantify the energy harvesting, transmission and conversion efficiency of the proposed system and compare it with existing systems.

Maternal sleep deprivation can trigger or aggravate psychosomatic problems such as depression, anxiety and stress that can directly influence maternal safety, with consequences for the baby's and mother's sleep. Such conditions can affect the family's quality of life and child development. Objective: To correlate maternal security with maternal state anxiety scores and the mother's and baby's total sleep time. Method: Cross-sectional study carried out with 96 mothers of babies aged 10 to 24 months, accompanied by nursing professionals linked to a Federal University in Northeast Brazil. Study variables were maternal security, maternal state anxiety scores, infant latency and sleep time, and total nocturnal sleep time of mother and infant. Maternal safety was calculated using a four-point Likert scale (1=not at all safe, 2=somewhat safe, 3=very safe, 4=completely safe). Maternal anxiety was measured by State-Trait Anxiety Inventory, state-anxiety subscale whose scores vary from 20 to 80 points, and the higher the score, the higher the anxiety levels. Scores below 33 are considered mild; from 33 to 49, moderate and above 49, high. As for the total nocturnal sleep time, values between 7-9 hours of sleep were considered adequate for mothers, and values between 9-12 hours for the baby, according to the guidelines of the National Sleep Foundation. For the sleep latency time, a time equal to or less than 20 min was considered adequate. It is noteworthy that the latency time and the time of night sleep of the mother and the baby were obtained by the mother's subjective report. To correlate the data, Spearman's correlation was used in the statistical package R version 3.6.3. Results: 96 women and babies participated, aged 22 to 38 years (mean 30.8) and 10 to 24 months (mean 14.7), respectively. The average of maternal security was 2.89 (unsafe); Mean maternal state anxiety scores were 43.75 (moderate anxiety). The babies' average sleep latency time was 39.6 min (>20 min). The mean sleep times of the mother and baby were, respectively, 6h and 42min and 8h and 19min, both less than the recommended nocturnal sleep time. Maternal security was positively correlated with maternal state anxiety scores (rh=266, p=0.009) and negatively correlated with infant sleep latency (rh= -0.30. P=0.003). Baby sleep time was positively correlated with maternal sleep time. (rh 0.46, p<0.001). Conclusion: The more secure the mothers considered themselves, the higher the anxiety scores and the shorter the baby's sleep latency. Also, the longer the baby sleeps, the longer the mother sleeps. Thus, interventions are needed to promote the quality and efficiency of sleep for both mother and baby. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sleep" title="sleep">sleep</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=infant" title=" infant"> infant</a>, <a href="https://publications.waset.org/abstracts/search?q=mother-child%20relations" title=" mother-child relations"> mother-child relations</a> </p> <a href="https://publications.waset.org/abstracts/167836/safety-and-maternal-anxiety-in-mothers-and-babys-sleep-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167836.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">149</span> Patient-Specific Modeling Algorithm for Medical Data Based on AUC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20Ribeiro">Guilherme Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Oliveira"> Alexandre Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Ferreira"> Antonio Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyam%20Visweswaran"> Shyam Visweswaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Gregory%20Cooper"> Gregory Cooper</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Patient-specific models are instance-based learning algorithms that take advantage of the particular features of the patient case at hand to predict an outcome.

Due to their operational characteristics, they can generate time-varying harmonic and inter-harmonic distortions. For this reason, the application of methods of measurement based on traditional Fourier analysis, as proposed by IEC 61000-4-7, can provide inaccurate results. Considering the aspects mentioned herein, came the idea of the development of this work which aims to present the results of a comparative evaluation between a methodology arising from the combination of the Prony method with the Kalman filter and another method based on the IEC 61000-4-30 and IEC 61000-4-7 standards. Employed in this study were synthetic signals and data acquired through measurements in a 50kWp photovoltaic installation. <p class="card-text"><strong>Keywords:</strong> <a
