Information and Communication Technology has the potential to contribute towards reducing isolation, loneliness, and to assist in improving interpersonal relations and fostering acculturation processes. Therefore, the use of mobile phones by refugees might contribute to their social connectedness. This paper aims to demonstrate how existing literature has shown how the use of mobile phones by refugees should engender social connectedness amongst the refugees. Data for the study are drawn from existing literature; we searched a number of electronic databases for papers published between 2010 and 2019. The main findings of the study relate to the use of mobile phones by refugees to (i) create a sense of belonging, (ii) maintain relationships, and (iii) advance the acculturation process. The analysis highlighted a gap in the research over refugees and social connectedness. In particular, further studies should consider evaluating the differences between those who have a refugee permit, those who are waiting for the refugee permit, and those whose request was denied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=belonging" title="belonging">belonging</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20phones" title=" mobile phones"> mobile phones</a>, <a href="https://publications.waset.org/abstracts/search?q=refugees" title=" refugees"> refugees</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20connectedness" title=" social connectedness"> social connectedness</a> </p> <a href="https://publications.waset.org/abstracts/116779/the-use-of-mobile-phones-by-refugees-to-create-social-connectedness-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116779.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">204</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">23</span> The Effects of Mobile Phones in Mitigating Cultural Shock amongst Refugees: Case of South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Vuningoma">Sarah Vuningoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Rosa%20Lorini"> Maria Rosa Lorini</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallace%20Chigona"> Wallace Chigona</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The potential of mobile phones is evident in their ability to address isolation and loneliness, support the improvement of interpersonal relations, and contribute to the facilitation of assimilation processes. Mobile phones can play a role in facilitating the integration of refugees into a new environment. This study aims to evaluate the impact of mobile phone use on helping refugees navigate the challenges posed by cultural differences in the host country. Semi-structured interviews were employed to collect data for the study, involving a sample size of 27 participants. Participants in the study were refugees based in South Africa, and thematic analysis was the chosen method for data analysis. The research highlights the numerous challenges faced by refugees in their host nation, including a lack of local cultural skills, the separation of family and friends from their countries of origin, hurdles in acquiring legal documentation, and the complexities of assimilating into the unfamiliar community. The use of mobile phones by refugees comes with several advantages, such as the advancement of language and cultural understanding, seamless integration into the host country, streamlined communication, and the exploration of diverse opportunities. Concurrently, mobile phones allow refugees in South Africa to manage the impact of culture shock. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20phones" title="mobile phones">mobile phones</a>, <a href="https://publications.waset.org/abstracts/search?q=culture%20shock" title=" culture shock"> culture shock</a>, <a href="https://publications.waset.org/abstracts/search?q=refugees" title=" refugees"> refugees</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/159367/the-effects-of-mobile-phones-in-mitigating-cultural-shock-amongst-refugees-case-of-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159367.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">90</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">22</span> Analytical Comparison of Conventional Algorithms with Vedic Algorithm for Digital Multiplier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akhilesh%20G.%20Naik">Akhilesh G.

Modern processing applications require suitable pipelined approaches, and therefore, algorithms that are friendlier with pipelined architectures. Traditional algorithms like Wallace Tree, Radix-4 Booth, Radix-8 Booth, Dadda architectures have been proven to be comparatively slow for pipelined architectures. These architectures, therefore, need to be optimized or combined with other architectures amongst them to enhance its performances and to be made suitable for pipelined hardware/architectures. Recently, Vedic algorithm mathematically has proven to be efficient by appearing to be less complex and with fewer steps for its output establishment and have assumed renewed importance. This paper describes and shows how the Vedic algorithm can be better suited for pipelined architectures and also can be combined with traditional architectures and algorithms for enhancing its ability even further. In this paper, we also established that for complex applications on DSP and other microcontroller architectures, using Vedic approach for multiplication proves to be the best available and efficient option. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wallace%20Tree" title="Wallace Tree">Wallace Tree</a>, <a href="https://publications.waset.org/abstracts/search?q=Radix-4%20Booth" title=" Radix-4 Booth"> Radix-4 Booth</a>, <a href="https://publications.waset.org/abstracts/search?q=Radix-8%20Booth" title=" Radix-8 Booth"> Radix-8 Booth</a>, <a href="https://publications.waset.org/abstracts/search?q=Dadda" title=" Dadda"> Dadda</a>, <a href="https://publications.waset.org/abstracts/search?q=Vedic" title=" Vedic"> Vedic</a>, <a href="https://publications.waset.org/abstracts/search?q=Single-Stage%20Karatsuba%20%28SSK%29" title=" Single-Stage Karatsuba (SSK)"> Single-Stage Karatsuba (SSK)</a>, <a href="https://publications.waset.org/abstracts/search?q=Looped%20Karatsuba%20%28LK%29" title=" Looped Karatsuba (LK)"> Looped Karatsuba (LK)</a> </p> <a href="https://publications.waset.org/abstracts/86906/analytical-comparison-of-conventional-algorithms-with-vedic-algorithm-for-digital-multiplier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86906.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">169</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">21</span> Social Learning and the Flipped Classroom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Albin%20Wallace">Albin Wallace</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the use of social learning platforms in conjunction with the emergent pedagogy of the ‘flipped classroom’.

Traditional methods of protecting the electrical grid have relied on relaying systems receiving voltage and current inputs from inductive instruments transformers (IT). This method has provided robust and stable performance throughout the years. Today with the advent of new non-conventional transformers (NCIT) and sensors, the electrical landscape is changing. These new systems have to ability to provide the same electrical performance as traditional instrument transformers with the added features of data acquisition, communication, smaller footprint, lower cost and resistance to GMD/GIC events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-conventional%20instrument%20transformers" title="non-conventional instrument transformers">non-conventional instrument transformers</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20substations" title=" digital substations"> digital substations</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grids" title=" smart grids"> smart grids</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-grids" title=" micro-grids"> micro-grids</a> </p> <a href="https://publications.waset.org/abstracts/169714/feasiblity-of-replacing-inductive-instrument-transformers-with-non-conventional-intrument-transformers-to-replace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169714.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">82</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">17</span> Embedded Electrochemistry with Miniaturized, Drone-Based, Potentiostat System for Remote Detection Chemical Warfare Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amer%20Dawoud">Amer Dawoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesy%20Motchaalangaram"> Jesy Motchaalangaram</a>, <a href="https://publications.waset.org/abstracts/search?q=Arati%20Biswakarma"> Arati Biswakarma</a>, <a href="https://publications.waset.org/abstracts/search?q=Wujan%20Mio"> Wujan Mio</a>, <a href="https://publications.waset.org/abstracts/search?q=Karl%20Wallace"> Karl Wallace</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of an embedded miniaturized drone-based system for remote detection of Chemical Warfare Agents (CWA) is proposed.

Vibration analysis methods have the potential to be combined with artificial intelligence systems where an automatic diagnostic method can be approached. An automatic fault diagnosis approach could be a good option to minimize human error and to provide a precise machine fault classification. This work aims to introduce an approach to centrifugal pump fault diagnosis based on artificial intelligence and genetic algorithm systems. An overview of the future works, research methodology and proposed experimental setup is presented and discussed. The expected results and outcomes based on the experimental work are illustrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=centrifugal%20pump%20setup" title="centrifugal pump setup">centrifugal pump setup</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20analysis" title=" vibration analysis"> vibration analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/66155/experimental-set-up-for-investigation-of-fault-diagnosis-of-a-centrifugal-pump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66155.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">410</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">14</span> Positioning Food Safety in Halal Assurance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marin%20Neio%20Demirci">Marin Neio Demirci</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Mei%20Soon"> Jan Mei Soon</a>, <a href="https://publications.waset.org/abstracts/search?q=Carol%20A.%20Wallace"> Carol A.

Muslims are allowed to eat halal and wholesome food that has been provided for them. However, some of the main prohibitions are swine flesh, blood, carrion, animals not slaughtered according to Islamic laws and alcoholic drinks. At present Halal assurance is in a complicated state, with various Halal standards differing from each other without gaining mutual acceptance. The world is starting to understand the need for an influential globally accepted standard that would open doors to global markets and gain consumer confidence. This paper discusses issues mainly related to food safety in Halal assurance. The aim was to discover and describe the approach to food safety requirements in Halal food provision and how this is incorporated in the Halal assurance systems. The position of food safety regulation within Halal requirements or Halal standards’ requirements for food safety is still unclear. This review also considers whether current Halal standards include criteria in common with internationally accepted food hygiene standards and emphasizes the potential of using the HACCP system for Halal assurance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=certification" title="certification">certification</a>, <a href="https://publications.waset.org/abstracts/search?q=GHP" title=" GHP"> GHP</a>, <a href="https://publications.waset.org/abstracts/search?q=HACCP" title=" HACCP"> HACCP</a>, <a href="https://publications.waset.org/abstracts/search?q=Halal%20standard" title=" Halal standard"> Halal standard</a> </p> <a href="https://publications.waset.org/abstracts/55352/positioning-food-safety-in-halal-assurance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55352.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">352</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">13</span> Delayed Disclosure: Factors Influencing Coming Out Decisions Among Transgender Adolescents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wallace%20Wong">Wallace Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Julia%20Toews"> Julia Toews</a>, <a href="https://publications.waset.org/abstracts/search?q=Kirsten%20Graham"> Kirsten Graham</a>, <a href="https://publications.waset.org/abstracts/search?q=Teija%20Yli-Renko"> Teija Yli-Renko</a>, <a href="https://publications.waset.org/abstracts/search?q=Dorcas%20Chau"> Dorcas Chau</a>, <a href="https://publications.waset.org/abstracts/search?q=Judith%20Lai"> Judith Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Momoka%20Nabatame"> Momoka Nabatame</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many transgender individuals report recognizing their non-cisgender identity in early childhood. However, numerous transgender adolescents choose to delay coming out to their family or friends until after puberty. This study explored factors influencing this decision by analyzing data from over 100 cases of transgender adolescents who disclosed their identity post-puberty. Using a qualitative thematic analysis approach, we identified key factors affecting this choice, including fear of rejection, lack of affirming resources, internalized transphobia, and safety concerns. The study also revealed the positive impact of increased transgender visibility and online support communities in facilitating later coming-out experiences. Our findings highlight the intersection of personal, social, and environmental factors contributing to disclosure timing for transgender adolescents. These insights can inform supportive interventions and policies to assist transgender youth throughout their coming out process, regardless of when it occurs. This research contributes to a deeper understanding of the challenges faced by transgender adolescents and the support they need during this critical period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transgender" title="transgender">transgender</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20identity" title=" gender identity"> gender identity</a>, <a href="https://publications.waset.org/abstracts/search?q=coming%20out" title=" coming out"> coming out</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a> </p> <a href="https://publications.waset.org/abstracts/192452/delayed-disclosure-factors-influencing-coming-out-decisions-among-transgender-adolescents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192452.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">20</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">12</span> Material Characterization of Medical Grade Woven Bio-Fabric for Use in ABAQUS *FABRIC Material Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lewis%20Wallace">Lewis Wallace</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Dempster"> William Dempster</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Nash"> David Nash</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandros%20Boukis"> Alexandros Boukis</a>, <a href="https://publications.waset.org/abstracts/search?q=Craig%20Maclean"> Craig Maclean</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper, through traditional test methods and close adherence to international standards, presents a characterization study of a woven Polyethylene Terephthalate (PET). Testing is undergone in the axial, shear, and out-of-plane (bend) directions, and the results are fitted to the *FABRIC material model with ABAQUS FEA. The non-linear behaviors of the fabric in the axial and shear directions and behaviors on the macro scale are explored at the meso scale level. The medical grade bio-fabric is tested in untreated and heat-treated forms, and deviations are closely analyzed at the micro, meso, and macro scales to determine the effects of the process. The heat-treatment process was found to increase the stiffness of the fabric during axial and bending stiffness testing but had a negligible effect on the shear response. The ability of *FABRIC to capture behaviors unique to fabric deformation is discussed, whereby the unique phenomenological input can accurately represent the experimentally derived inputs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental%20techniques" title="experimental techniques">experimental techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA%20modelling" title=" FEA modelling"> FEA modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20characterization" title=" materials characterization"> materials characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=post-processing%20techniques" title=" post-processing techniques"> post-processing techniques</a> </p> <a href="https://publications.waset.org/abstracts/170670/material-characterization-of-medical-grade-woven-bio-fabric-for-use-in-abaqus-fabric-material-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170670.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">95</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">11</span> Reclaimed Tire and Carbon Black Mixture Effect on Mechanical Properties of Rubber Blends SBR/NR/BRcis Uses as Damping Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samir%20Hassan%20AL-Nesrawy">Samir Hassan AL-Nesrawy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Al-Maamori"> Mohammed Al-Maamori</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20S.%20Hassani"> A.

After having been certain about attaining the physical and mechanical properties of the new samples which are similar to the levels of their standard ones, damping properties for the new samples have been measured and compared with those of the standard fenders. The new samples included four rubber blends from (SBR/NR/BR-cis) and four loading levels of mix carbon black (type N-375) and reclaim to become sixteen compound contain SBR(100,60,60,60), NR(0,10,20,30), BRcis(30,20,10,0) and loading level for C.B, Reclaim (10,20,30,40). Damping measurements have been carried out by the method Free Vibration Resilience Pendulum method (by using Wallace R2-Dunlop Tripsometer) and from this Resilience Pendulum method, both the resilience percentage value (R%) and time decay (t0) have been measured at 50oC. We found that the results of this method proved that the increment of C.B, Reclaim level in these robber composite lead to decreasing the resiliency (R%) and damping time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damping%20materials" title="damping materials">damping materials</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20black%20mixture%20effect" title=" carbon black mixture effect"> carbon black mixture effect</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber%20blends%20SBR%2FNR%2FBRcis" title=" rubber blends SBR/NR/BRcis "> rubber blends SBR/NR/BRcis </a> </p> <a href="https://publications.waset.org/abstracts/2802/reclaimed-tire-and-carbon-black-mixture-effect-on-mechanical-properties-of-rubber-blends-sbrnrbrcis-uses-as-damping-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2802.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">452</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">10</span> IL-21 Production by CD4+ Effector T Cells and Frequency of Circulating Follicular Helper T Cells Are Increased in Type 1 Diabetes Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferreira%20RC">Ferreira RC</a>, <a href="https://publications.waset.org/abstracts/search?q=Simons%20HZ"> Simons HZ</a>, <a href="https://publications.waset.org/abstracts/search?q=Thompson%20WS"> Thompson WS</a>, <a href="https://publications.waset.org/abstracts/search?q=Cutler%20AJ"> Cutler AJ</a>, <a href="https://publications.waset.org/abstracts/search?q=Dopico%20XC"> Dopico XC</a>, <a href="https://publications.waset.org/abstracts/search?q=Smyth%20DJ"> Smyth DJ</a>, <a href="https://publications.waset.org/abstracts/search?q=Mashar%20M"> Mashar M</a>, <a href="https://publications.waset.org/abstracts/search?q=Schuilenburg%20H"> Schuilenburg H</a>, <a href="https://publications.waset.org/abstracts/search?q=Walker%20NM"> Walker NM</a>, <a href="https://publications.waset.org/abstracts/search?q=Dunger%20DB"> Dunger DB</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallace%20C"> Wallace C</a>, <a href="https://publications.waset.org/abstracts/search?q=Todd%20JA"> Todd JA</a>, <a href="https://publications.waset.org/abstracts/search?q=Wicker%20LS"> Wicker LS</a>, <a href="https://publications.waset.org/abstracts/search?q=Pekalski%20ML"> Pekalski ML</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Type 1 diabetes is caused by autoimmune destruction of insulin-secreting beta cells in the pancreas. T cells are known to play an important role in this immune-mediated destruction; however, there is no general consensus regarding alterations in cytokine production or T cell subsets in peripheral blood of patients with type 1 diabetes. Using polychromatic flow cytometry of peripheral blood mononuclear cells (PBMCs), we assessed production of the proinflammatory cytokines IL-21, IFN-γ and IL-17 by memory CD4 T effector (Teff) cells in 69 patients with type 1 diabetes and 61 healthy donors. We found a 21.9% (95% CI 5.8, 40.2; p = 3.9 × 10(-3)) higher frequency of IL-21(+) CD45RA(-) memory CD4(+) Teffs in patients with type 1 diabetes (geometric mean 5.92% [95% CI 5.44, 6.44]) compared with healthy donors (geometric mean 4.88% [95% CI 4.33, 5.50]). In a separate cohort of 30 patients with type 1 diabetes and 32 healthy donors, we assessed the frequency of circulating T follicular helper (Tfh) cells in whole blood. Consistent with the increased production of IL-21, we also found a 14.9% increase in circulating Tfh cells in the patients with type 1 diabetes (95% CI 2.9, 26.9; p = 0.016). Analysis of IL-21 production by PBMCs from a subset of 46 of the 62 donors immunophenotyped for Tfh showed that frequency of Tfh cells was associated with the frequency of IL-21+ cells (r2 = 0.174, p = 0.004). These results indicate that increased IL-21 production is likely to be an aetiological factor in the pathogenesis of type 1 diabetes that could be considered as a potential therapeutic target. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=T%20follicular%20helper%20cell" title="T follicular helper cell">T follicular helper cell</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-21" title=" IL-21"> IL-21</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-17" title=" IL-17"> IL-17</a>, <a href="https://publications.waset.org/abstracts/search?q=type%201%20diabetes" title=" type 1 diabetes"> type 1 diabetes</a> </p> <a href="https://publications.waset.org/abstracts/32813/il-21-production-by-cd4-effector-t-cells-and-frequency-of-circulating-follicular-helper-t-cells-are-increased-in-type-1-diabetes-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32813.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">380</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">9</span> Biocompatibility and Electrochemical Assessment of Biomedical Ti-24Nb-4Zr-8Sn Produced by Spark Plasma Sintering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jerman%20Madonsela">Jerman Madonsela</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallace%20%20Matizamhuka"> Wallace Matizamhuka</a>, <a href="https://publications.waset.org/abstracts/search?q=Akiko%20%20Yamamoto"> Akiko Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ronald%20Machaka"> Ronald Machaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Brendon%20Shongwe"> Brendon Shongwe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, biocompatibility evaluation of nanostructured near beta Ti-24Nb-4Zr-8Sn (Ti2448) alloy with non-toxic elements produced utilizing Spark plasma sintering (SPS) of very fine microsized powders attained through mechanical alloying was performed. The results were compared with pure titanium and Ti-6Al-4V (Ti64) alloy. Cell proliferation test was performed using murine osteoblastic cells, MC3T3-E1 at two cell densities; 400 and 4000 cells/mL for 7 days incubation. Pure titanium took a lead under both conditions suggesting that the presence of other oxide layers influence cell proliferation. No significant difference in cell proliferation was observed between Ti64 and Ti2448. Potentiodynamic measurement in Hanks, 0.9% NaCl and cell culture medium showed no distinct difference on the anodic polarization curves of the three alloys, indicating that the same anodic reaction occurred on their surface but with different rates. However, Ti2448 showed better corrosion resistance in cell culture medium with a slightly lower corrosion rate of 2.96 nA/cm2 compared to 4.86 nA/cm2 and 5.62 nA/cm2 of Ti and Ti64 respectively. Ti2448 adsorbed less protein as compared to Ti and Ti64 though no notable difference in surface wettability was observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title="biocompatibility">biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoblast" title=" osteoblast"> osteoblast</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20wettability" title=" surface wettability"> surface wettability</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20adsorption" title=" protein adsorption"> protein adsorption</a> </p> <a href="https://publications.waset.org/abstracts/93233/biocompatibility-and-electrochemical-assessment-of-biomedical-ti-24nb-4zr-8sn-produced-by-spark-plasma-sintering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93233.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">222</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">8</span> Blade Runner and Slavery in the 21st Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B%C3%BClent%20Diken">Bülent Diken</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper looks to set Ridley Scott’s original film Blade Runner (1982) and Denis Villeneuve’s Blade Runner 2049 (2017) in order to provide an analysis of both films with respect to the new configurations of slavery in the 21st century. Both Blade Runner films present a de-politicized society that oscillates between two extremes: the spectral (the eye, optics, digital communications) and the biopolitical (the body, haptics). On the one hand, recognizing the subject only as a sign, the society of the spectacle registers, identifies, produces and reproduces the subject as a code. At the same time, though, the subject is constantly reduced to a naked body, to bare life, for biometric technologies to scan it as a biological body or body parts. Being simultaneously a pure code (word without body) and an instrument slave (body without word), the replicants are thus the paradigmatic subjects of this society. The paper focuses first on the similarity: both films depict a relationship between masters and slaves, that is, a despotic relationship. The master uses the (body of the) slave as an instrument, as an extension of his own body. Blade Runner 2019 frames the despotic relation in this classical way through its triangulation with the economy (the Tyrell Corporation) and the slave-replicants’ dissent (rejecting their reduction to mere instruments). In a counter-classical approach, in Blade Runner 2049, the focus shifts to another triangulation: despotism, economy (the Wallace Corporation) and consent (of replicants who no longer perceive themselves as slaves). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blade%20Runner" title="Blade Runner">Blade Runner</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20spectacle" title=" the spectacle"> the spectacle</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-politics" title=" bio-politics"> bio-politics</a>, <a href="https://publications.waset.org/abstracts/search?q=slavery" title=" slavery"> slavery</a>, <a href="https://publications.waset.org/abstracts/search?q=imstrumentalisation" title=" imstrumentalisation"> imstrumentalisation</a> </p> <a href="https://publications.waset.org/abstracts/177328/blade-runner-and-slavery-in-the-21st-century" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177328.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">69</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">7</span> Screening for Diabetes in Patients with Chronic Pancreatitis: The Belfast Trust Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riyas%20Peringattuthodiyil">Riyas Peringattuthodiyil</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Taylor"> Mark Taylor</a>, <a href="https://publications.waset.org/abstracts/search?q=Ian%20Wallace"> Ian Wallace</a>, <a href="https://publications.waset.org/abstracts/search?q=Ailish%20Nugent"> Ailish Nugent</a>, <a href="https://publications.waset.org/abstracts/search?q=Mike%20Mitchell"> Mike Mitchell</a>, <a href="https://publications.waset.org/abstracts/search?q=Judith%20Thompson"> Judith Thompson</a>, <a href="https://publications.waset.org/abstracts/search?q=Allison%20McKee"> Allison McKee</a>, <a href="https://publications.waset.org/abstracts/search?q=Philip%20C.%20Johnston"> Philip C.

Background: Patients with chronic pancreatitis are at risk of developing diabetes, earlier diagnosis with subsequent multi-disciplinary input has the potential to improve clinical outcomes. Methods: Clinical and laboratory data of patients with chronic pancreatitis were obtained through the Northern Ireland Electronic Healthcare Record (NIECR), specialist hepatobiliary, and gastrointestinal clinics. Patients were invited to have a blood test for HbA1c. Newly diagnosed patients with diabetes were then invited to attend a dedicated Belfast City Hospital (BCH) specialist chronic pancreatitis and diabetes clinic for follow up. Results: A total of 89 chronic pancreatitis patients were identified; Male54; Female:35, mean age 52 years, range 12-90 years. Aetiology of CP included alcohol 52/89 (58%), gallstones 18/89 (20%), idiopathic 10/89 11%, 2 were genetic, 1: post ECRP, 1: IgG autoimmune, 1: medication induced, 1: lipoprotein lipase deficiency 1: mumps, 1: IVDU and 1: pancreatic divisum. No patients had pancreatic carcinoma. Mean duration of CP was nine years, range 3-30 years. 15/89 (16%) of patients underwent previous pancreatic surgery/resections. Recent mean BMI was 25.1 range 14-40 kg/m². 62/89 (70%) patients had HbA1c performed. Mean HbA1c was 42 mmol/mol, range 27-97mmol/mol, 42/62 (68%) had normal HbA1c (< 42 mmol/mol) 13/62 (21%) had pre-diabetes (42-47mmol/mol) and 7/62 (11%) had diabetes (≥ 48 mmol/mol). Conclusions: Of those that participated in the screening program around one-third of patients with CP had glycaemic control in the pre and diabetic range. Potential opportunities for improving screening rates for diabetes in this cohort could include regular yearly testing at gastrointestinal and hepatobiliary clinics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pancreatogenic%20diabetes" title="pancreatogenic diabetes">pancreatogenic diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20pancreatitis" title=" chronic pancreatitis"> chronic pancreatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=trust%20experience" title=" trust experience"> trust experience</a> </p> <a href="https://publications.waset.org/abstracts/97553/screening-for-diabetes-in-patients-with-chronic-pancreatitis-the-belfast-trust-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97553.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">159</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">6</span> Proliferative Effect of Some Calcium Channel Blockers on the Human Embryonic Kidney Cell Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lukman%20Ahmad%20Jamil">Lukman Ahmad Jamil</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20M.%20Wallace"> Heather M.

However, these associations were enmeshed with controversies in the absence of laboratory based studies to back up those claims. Aim: The aim of this study was to determine in mechanistic terms the association between the long-term administration of nifedipine and diltiazem and increased risk of developing cancer using the human embryonic kidney (HEK293) cell line. Methods: Cell counting using the Trypan blue dye exclusion and 3-4, 5-Dimethylthiazol-2-yl-2, 5-diphenyl-tetrazolium bromide (MTT) assays were used to investigate the effect of nifedipine and diltiazem on the growth pattern of HEK293 cells. Protein assay using modified Lowry method and analysis of intracellular polyamines concentration using Liquid Chromatography – Tandem Mass Spectrometry (LC-MS) were performed to ascertain the mechanism through which chronic use of nifedipine increases the risk of developing cancer. Results: Both nifedipine and diltiazem significantly increased the proliferation of HEK293 cells dose and time dependently. This proliferative effect after 24, 48 and 72-hour incubation period was observed at 0.78, 1.56 and 25 µM for nifedipine and 0.39, 1.56 and 25 µM for diltiazem, respectively. The increased proliferation of the cells was found to be statistically significantly (p<0.05). Furthermore, the increased proliferation of the cells induced by nifedipine was associated with the increase in the protein content and elevated intracellular polyamines concentration level. Conclusion: The chronic use of nifedipine is associated with increased proliferation of cells with concomitant elevation of polyamines concentration and elevated polyamine levels have been implicated in many malignant transformations and hence, these provide a possible explanation on the link between long term use of nifedipine and development of some human cancers. Further studies are needed to evaluate the cause of this association. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=nifedipine" title=" nifedipine"> nifedipine</a>, <a href="https://publications.waset.org/abstracts/search?q=polyamine" title=" polyamine"> polyamine</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferation" title=" proliferation"> proliferation</a> </p> <a href="https://publications.waset.org/abstracts/77684/proliferative-effect-of-some-calcium-channel-blockers-on-the-human-embryonic-kidney-cell-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77684.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">198</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">5</span> Prompting and Encouraging Community Hydration through Education: A Realist Review and Evaluation Exploring Hydration in a Population at Risk of Frailty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Davies">Mark Davies</a>, <a href="https://publications.waset.org/abstracts/search?q=Carolyn%20Wallace"> Carolyn Wallace</a>, <a href="https://publications.waset.org/abstracts/search?q=Christina%20Lloydwin"> Christina Lloydwin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20Powell"> Tom Powell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Frailty is increasingly recognized as a public health problem within an aging population. It is often characterized as an accumulation of clinical symptoms with progressive decline. We contend that dehydration is potentially the missing link driving the cycle of frailty; it contributes to malnutrition and cognitive decline and is a risk factor for other conditions. Frailty may also impact on fluid intake in cognitively intact older adults, indicating the cyclical nature of dehydration contributing to increasing frailty. Aim: To examine the relationships between fluid, hydration, and frailty in older adults in order to determine what works, for whom, how, why, and in what circumstances. Methods: A Realist Synthesis was first undertaken with n=50 studies, leading to the development of a Refined Programme Theory (RPT) articulating what hydration interventions work, for whom, to what degree, in what contexts, and how & why. Within the subsequent evaluation, the RPT was further confirmed/refuted/refined following semi-structured interviews with n=8 participants (healthcare professionals and patients). The RAMESES Quality Standards were followed throughout the study. Results: The Refined Programme Theory (RPT) highlighted three factors that result in optimized hydration for frail older people, i.e., Developing an Understanding Around Hydration, Empowering Participation, and System Reconfiguration. Our RPT indicates that hydration interventions work by developing an understanding of the importance of hydration, mitigating physical & cognitive barriers, increasing the agency of the patient, using a prompting process to reinforce drinking behavior, and routinizing hydration as a dimension of overall care. Conclusion: The study indicates that a greater understanding of the importance of hydration is required for all parties. Patients also require physical and psychological support if they are to be active agents in meeting their hydration needs. At a wider ‘system’ level, organizations must work in an integrated manner introducing processes that enable continuing professional development (CPD), encourage ongoing holistic assessment, and routinize hydration support. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frailty" title="frailty">frailty</a>, <a href="https://publications.waset.org/abstracts/search?q=dehydration" title=" dehydration"> dehydration</a>, <a href="https://publications.waset.org/abstracts/search?q=older%20adults" title=" older adults"> older adults</a>, <a href="https://publications.waset.org/abstracts/search?q=realist%20review" title=" realist review"> realist review</a>, <a href="https://publications.waset.org/abstracts/search?q=realist%20evaluation" title=" realist evaluation"> realist evaluation</a> </p> <a href="https://publications.waset.org/abstracts/165087/prompting-and-encouraging-community-hydration-through-education-a-realist-review-and-evaluation-exploring-hydration-in-a-population-at-risk-of-frailty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165087.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">75</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">4</span> Knowledge Transfer to Builders in Improving Housing Resilience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Shaikh">Saima Shaikh</a>, <a href="https://publications.waset.org/abstracts/search?q=Andre%20Brown"> Andre Brown</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallace%20Enegbuma"> Wallace Enegbuma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Earthquakes strike both developed and developing countries, causing tremendous damage and the loss of lives of millions of people, mainly due to the collapsing of buildings, particularly in poorer countries. Despite the socio-economic and technological restrictions, the poorer countries have adopted proven and established housing-strengthening techniques from affluent countries. Rural communities are aware of the earthquake-strengthening mechanisms for improving housing resilience, but owing to socio-economic and technological constraints, the seismic guidelines are rarely implemented, resulting in informal construction practice. Unregistered skilled laborers make substantial contributions to the informal construction sector, particularly in rural areas where knowledge is scarce. Laborers employ their local expertise in house construction; however, owing to a lack of seismic expertise in safe building procedures, the authorities' regulated seismic norms are not applied. From the perspective of seismic knowledge transformation in safe buildings practices, the study focuses on the feasibility of seismic guidelines implementation. The study firstly employs a literature review of massive-scale reconstruction after the 2005 earthquake in rural Pakistan. The 2005-earthquake damaged over 400,000 homes, killed 70,000 people and displaced 2.8 million people. The research subsequently corroborated the pragmatic approach using questionnaire field survey among the rural people in 2005-earthquake affected areas. Using the literature and the questionnaire survey, the research analyzing people's perspectives on technical acceptability, financial restrictions, and socioeconomic viability and examines the effectiveness of seismic knowledge transfer in safe buildings practices. The findings support the creation of a knowledge transfer framework in disaster mitigation and recovery planning, assisting rural communities and builders in minimising losses and improving response and recovery, as well as improving housing resilience and lowering vulnerabilities. Finally, certain conclusions are obtained in order to continue the resilience research. The research can be further applied in rural areas of developing countries having similar construction practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquakes" title="earthquakes">earthquakes</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20transfer" title=" knowledge transfer"> knowledge transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20construction%20practices" title=" informal construction practices"> informal construction practices</a> </p> <a href="https://publications.waset.org/abstracts/139220/knowledge-transfer-to-builders-in-improving-housing-resilience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139220.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">173</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">3</span> Utilization of Process Mapping Tool to Enhance Production Drilling in Underground Metal Mining Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidharth%20Talan">Sidharth Talan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar%20Sharma"> Sanjay Kumar Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Eoin%20Joseph%20Wallace"> Eoin Joseph Wallace</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikita%20Agrawal"> Nikita Agrawal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Underground mining is at the core of rapidly evolving metals and minerals sector due to the increasing mineral consumption globally. Even though the surface mines are still more abundant on earth, the scales of industry are slowly tipping towards underground mining due to rising depth and complexities of orebodies. Thus, the efficient and productive functioning of underground operations depends significantly on the synchronized performance of key elements such as operating site, mining equipment, manpower and mine services. Production drilling is the process of conducting long hole drilling for the purpose of charging and blasting these holes for the production of ore in underground metal mines. Thus, production drilling is the crucial segment in the underground metal mining value chain. This paper presents the process mapping tool to evaluate the production drilling process in the underground metal mining operation by dividing the given process into three segments namely Input, Process and Output. The three segments are further segregated into factors and sub-factors. As per the study, the major input factors crucial for the efficient functioning of production drilling process are power, drilling water, geotechnical support of the drilling site, skilled drilling operators, services installation crew, oils and drill accessories for drilling machine, survey markings at drill site, proper housekeeping, regular maintenance of drill machine, suitable transportation for reaching the drilling site and finally proper ventilation. The major outputs for the production drilling process are ore, waste as a result of dilution, timely reporting and investigation of unsafe practices, optimized process time and finally well fragmented blasted material within specifications set by the mining company. The paper also exhibits the drilling loss matrix, which is utilized to appraise the loss in planned production meters per day in a mine on account of availability loss in the machine due to breakdowns, underutilization of the machine and productivity loss in the machine measured in drilling meters per unit of percussion hour with respect to its planned productivity for the day. The given three losses would be essential to detect the bottlenecks in the process map of production drilling operation so as to instigate the action plan to suppress or prevent the causes leading to the operational performance deficiency. The given tool is beneficial to mine management to focus on the critical factors negatively impacting the production drilling operation and design necessary operational and maintenance strategies to mitigate them.  <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=process%20map" title="process map">process map</a>, <a href="https://publications.waset.org/abstracts/search?q=drilling%20loss%20matrix" title=" drilling loss matrix"> drilling loss matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=SIPOC" title=" SIPOC"> SIPOC</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=percussion%20rate" title=" percussion rate"> percussion rate</a> </p> <a href="https://publications.waset.org/abstracts/94947/utilization-of-process-mapping-tool-to-enhance-production-drilling-in-underground-metal-mining-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94947.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">215</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">2</span> Using Virtual Reality Exergaming to Improve Health of College Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juanita%20Wallace">Juanita Wallace</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Jackson"> Mark Jackson</a>, <a href="https://publications.waset.org/abstracts/search?q=Bethany%20Jurs"> Bethany Jurs</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Exergames, VR games used as a form of exercise, are being used to reduce sedentary lifestyles in a vast number of populations. However, there is a distinct lack of research comparing the physiological response during VR exergaming to that of traditional exercises. The purpose of this study was to create a foundationary investigation establishing changes in physiological responses resulting from VR exergaming in a college aged population. Methods: In this IRB approved study, college aged students were recruited to play a virtual reality exergame (Beat Saber) on the Oculus Quest 2 (Facebook, 2021) in either a control group (CG) or training group (TG). Both groups consisted of subjects who were not habitual users of virtual reality. The CG played VR one time per week for three weeks and the TG played 150 min/week three weeks. Each group played the same nine Beat Saber songs, in a randomized order, during 30 minute sessions. Song difficulty was increased during play based on song performance. Subjects completed a pre- and posttests at which the following was collected: • Beat Saber Game Metrics: song level played, song score, number of beats completed per song and accuracy (beats completed/total beats) • Physiological Data: heart rate (max and avg.), active calories • Demographics Results: A total of 20 subjects completed the study; nine in the CG (3 males, 6 females) and 11 (5 males, 6 females) in the TG. • Beat Saber Song Metrics: The TG improved performance from a normal/hard difficulty to hard/expert. The CG stayed at the normal/hard difficulty. At the pretest there was no difference in game accuracy between groups. However, at the posttest the CG had a higher accuracy. • Physiological Data (Table 1): Average heart rates were similar between the TG and CG at both the pre- and posttest. However, the TG expended more total calories. Discussion: Due to the lack of peer reviewed literature on c exergaming using Beat Saber, the results of this study cannot be directly compared. However, the results of this study can be compared with the previously established trends for traditional exercise. In traditional exercise, an increase in training volume equates to increased efficiency at the activity. The TG should naturally increase in difficulty at a faster rate than the CG because they played 150 hours per week. Heart rate and caloric responses also increase during traditional exercise as load increases (i.e. speed or resistance). The TG reported an increase in total calories due to a higher difficulty of play. The song accuracy decreases in the TG can be explained by the increased difficulty of play. Conclusion: VR exergaming is comparable to traditional exercise for loads within the 50-70% of maximum heart rate. The ability to use VR for health could motivate individuals who do not engage in traditional exercise. In addition, individuals in health professions can and should promote VR exergaming as a viable way to increase physical activity and improve health in their clients/patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title="virtual reality">virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=exergaming" title=" exergaming"> exergaming</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate" title=" heart rate"> heart rate</a>, <a href="https://publications.waset.org/abstracts/search?q=wellness" title=" wellness"> wellness</a> </p> <a href="https://publications.waset.org/abstracts/143948/using-virtual-reality-exergaming-to-improve-health-of-college-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143948.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">187</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">1</span> Recurrent Neural Networks for Classifying Outliers in Electronic Health Record Clinical Text </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duncan%20Wallace">Duncan Wallace</a>, <a href="https://publications.waset.org/abstracts/search?q=M-Tahar%20Kechadi"> M-Tahar Kechadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, Machine Learning (ML) approaches have been successfully applied to an analysis of patient symptom data in the context of disease diagnosis, at least where such data is well codified. However, much of the data present in Electronic Health Records (EHR) are unlikely to prove suitable for classic ML approaches. Furthermore, as scores of data are widely spread across both hospitals and individuals, a decentralized, computationally scalable methodology is a priority. The focus of this paper is to develop a method to predict outliers in an out-of-hours healthcare provision center (OOHC). In particular, our research is based upon the early identification of patients who have underlying conditions which will cause them to repeatedly require medical attention. OOHC act as an ad-hoc delivery of triage and treatment, where interactions occur without recourse to a full medical history of the patient in question. Medical histories, relating to patients contacting an OOHC, may reside in several distinct EHR systems in multiple hospitals or surgeries, which are unavailable to the OOHC in question. As such, although a local solution is optimal for this problem, it follows that the data under investigation is incomplete, heterogeneous, and comprised mostly of noisy textual notes compiled during routine OOHC activities. Through the use of Deep Learning methodologies, the aim of this paper is to provide the means to identify patient cases, upon initial contact, which are likely to relate to such outliers. To this end, we compare the performance of Long Short-Term Memory, Gated Recurrent Units, and combinations of both with Convolutional Neural Networks. A further aim of this paper is to elucidate the discovery of such outliers by examining the exact terms which provide a strong indication of positive and negative case entries. While free-text is the principal data extracted from EHRs for classification, EHRs also contain normalized features. Although the specific demographical features treated within our corpus are relatively limited in scope, we examine whether it is beneficial to include such features among the inputs to our neural network, or whether these features are more successfully exploited in conjunction with a different form of a classifier. In this section, we compare the performance of randomly generated regression trees and support vector machines and determine the extent to which our classification program can be improved upon by using either of these machine learning approaches in conjunction with the output of our Recurrent Neural Network application. The output of our neural network is also used to help determine the most significant lexemes present within the corpus for determining high-risk patients. By combining the confidence of our classification program in relation to lexemes within true positive and true negative cases, with an inverse document frequency of the lexemes related to these cases, we can determine what features act as the primary indicators of frequent-attender and non-frequent-attender cases, providing a human interpretable appreciation of how our program classifies cases. <p
