Review of related work and literature revealed several important aspects to be considered when implementing the operation guide including Identify supporting IT groups, specify each group roles and responsibilities, formulate the IT operations in terms of processes (input/output), list each process main steps, provide the details of each process main step, develop the RACI (Responsible, Accountable, Consulted, and Informed) chart, highlight the process KPI’s, utilized systems, and forms. Identified aspects were then addressed in the actual implementation via several practices, including developing the operation guide for all IT supported operations, creating a shared folder for the operations guide, and announcing the implementation to all IT staff. The implementation of the mentioned practice was benchmarked, identified as best in class, and adopted by other internal organizations. Moreover, it was evident and appreciated by IT management. The significance of this study stems from the fact that it might be among the first studies in Saudi Arabia that propose a practical guideline to implement IT operations guide by IT organizations. Additional research significance comes from the study being conducted in Saudi Aramco, one of the world’s biggest integrated energy and petrochemical companies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=operations%20guide" title="operations guide">operations guide</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20implementation" title=" process implementation"> process implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Aramco%20company" title=" Saudi Aramco company"> Saudi Aramco company</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20technology" title=" information technology"> information technology</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20of%20procedure" title=" standard of procedure"> standard of procedure</a> </p> <a href="https://publications.waset.org/abstracts/156577/operations-guide-implementation-practice-in-information-technology-organizations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156577.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">2937</span> The Impacts of Technology on Operations Costs: The Mediating Role of Operation Flexibility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fazli%20Idris">Fazli Idris</a>, <a href="https://publications.waset.org/abstracts/search?q=Jihad%20Mohammad"> Jihad Mohammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aims to determine the impact of technology and service operations flexibility, which is divided into external flexibility and internal robustness, on operations costs. A mediation model is proposed that links technology to operations costs via operation flexibility. Drawing on a sample of 475 of operations managers of various service sectors in Malaysia and South Africa, Structural Equation Modeling (SEM) was employed to test the relationship using Smart-PLS procedures. It was found that a significant relationship was established between technologies to operations costs via both operations flexibility dimensions.

Three-dimensional Numerical study was performed to analyze the effect of adjustable guide vane for improving the airflow rate in axial fans. Grid independence test was done between five different meshes in order to choose the reliable mesh. In flow analyses, Reynolds averaged Navier-Stokes (RANS) equations was solved using three types of turbulence models named k-ɛ, k-ω and k-ω SST. The aerodynamic performances of the fan and guide vane were evaluated. Numerical method was validated by comparing with experimental test according to AMECA 210 standard. Results showed that, by using the adjustable guide vane the airflow rate is increased around 3% to 6 %. The maximum enhancement of the airflow rate was achieved when pressure was 374pa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20fan" title="axial fan">axial fan</a>, <a href="https://publications.waset.org/abstracts/search?q=adjustable%20guide%20vane" title=" adjustable guide vane"> adjustable guide vane</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=turbo%20machinery" title=" turbo machinery "> turbo machinery </a> </p> <a href="https://publications.waset.org/abstracts/44057/numerical-investigation-the-effect-of-adjustable-guide-vane-for-improving-the-airflow-rate-in-axial-fans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44057.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">337</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">2935</span> Visitor Expectation on a Tour Guide Business as Part of Promoting the Sustainability Tourism in Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kawinphat%20Lertpontmanee">Kawinphat Lertpontmanee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tourism industry in Thailand is regarded as an energizer of the domestic economy for several years.

Intermittent oro-esophageal (IOE) tube feeding is one of the well-known feeding methods for the dysphasia patients. However, it is hard to insert at the proper position in esophagus. In this study, we design and fabricate the IOE tube guide using 3-dimensional (3D) printer. The printed IOE tube is tested in a mannequin (Airway Management Trainer, Co., Ltd., Copenhagen, Denmark) mimicking human’s esophagus. The gag reflex point is measured as the design point in the mannequin. To avoid the gag reflex, we design various shapes of IOE tube guide. One structure is separated into three parts; biting part, part through oral cavity, connecting part to oro-esophageal. We designed 6 types of IOE tube guide adjusting length and angle of these three parts. To evaluate the IOE tube guide, it is inserted in the mannequin, and through the inserted guide, an endoscopic camera successfully arrived at the oro-esophageal. We had planned to apply this mannequin-based design experience to patients in near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dysphagia" title="dysphagia">dysphagia</a>, <a href="https://publications.waset.org/abstracts/search?q=feeding%20method" title=" feeding method"> feeding method</a>, <a href="https://publications.waset.org/abstracts/search?q=IOE%20tube%20guide" title=" IOE tube guide"> IOE tube guide</a>, <a href="https://publications.waset.org/abstracts/search?q=3-D%20printer" title=" 3-D printer"> 3-D printer</a> </p> <a href="https://publications.waset.org/abstracts/49780/mannequin-evaluation-of-3d-printed-intermittent-oro-esophageal-tube-guide-for-dysphagia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49780.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">434</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">2933</span> A Survey on E-Guide to Educational Tour Planning in Environmental Science among Standard Six Primary School Students the Ministry of Education Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.Halim%20Sahelan">A.Halim Sahelan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Halid%20Abu"> Mohd Halid Abu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamaluddin%20Hashim"> Jamaluddin Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulisman%20Maksom"> Zulisman Maksom</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Afif%20Md%20Nasir"> Mohd Afif Md Nasir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to assess the students' needs for the tour planning e-guide.

For example, the famous British Special Operations Executive (SOE) and the Americans’ Office for Strategic Services (OSS) – the forerunners of modern day CIA were born in World War 2. These special operations units were tasked with the conduct of sabotage and subversion activities behind enemy lines, placing great importance in forming Fifth Column activities and supporting resistance movements. This pointed to a paradoxical argument that modern day special operations is a product of Western modern military innovation but utilizing Eastern ways of ‘ungentlemanly’ warfare. This thesis is superfluous as special operations had been well practised by both ancient Western empires such as the Greeks and Romans, and around the same time in the East, such as in China, and Japan. This paper will describe the practice of special operations, first from the Western military history of the Greeks during the Peloponnesian war. It will then highlight the similar practice of special operations by the Near Eastern Assassins and Eastern militaries by using examples from the Chinese and the Japanese. This paper propounds that special operations, or ways of warfare as a whole, has no cultural and geographical divide, but rather very similarly practiced by men from all over the world. Ideas of fighting, killing and ultimately winning a war have similar undertones – attempts to find ways to win economically and at the least time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=special%20operations" title="special operations">special operations</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20culture" title=" strategic culture"> strategic culture</a>, <a href="https://publications.waset.org/abstracts/search?q=ways%20of%20warfare" title=" ways of warfare"> ways of warfare</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Tzu" title=" Sun Tzu"> Sun Tzu</a>, <a href="https://publications.waset.org/abstracts/search?q=Frontinus" title=" Frontinus"> Frontinus</a> </p> <a href="https://publications.waset.org/abstracts/61434/western-and-eastern-ways-of-special-warfare-the-strategic-history-of-special-operations-from-western-and-eastern-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61434.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">472</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">2930</span> Variations of the Modal Characteristics of the Feeding Stage with Different Preloaded Linear Guide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui-Pui%20Hung">Jui-Pui Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Run%20Chen"> Yong-Run Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei-Cheng%20Shih"> Wei-Cheng Shih</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Wei%20Lin"> Chun-Wei Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was aimed to assess the variations of the modal characteristics of the feeding stage with different linear guide modulus. The dynamic characteristics of the feeding stage were characterized in terms of the modal stiffness, modal frequency and modal damping, which are assessed from the vibration tests. According to the experimental measurements, the actual preload of the linear guide modulus was found to deviate from the rated values as setting in factory. This may be due to the assemblage errors of guide modules. For the stage with linear guides, the dynamic stiffness was affected to change by the preload set on the rolling balls. The variation of the dynamic stiffness at first and second modes is 20.8 and 10.5%, respectively when the linear guide preload is adjusted from medium and high amount. But the modal damping ratio is reduced by 8.97 and 9.65%, respectively. For high-frequency mode, the modal stiffness increases by 171.2% and the damping ratio reduced by 34.4%. Current results demonstrate the importance in the determining the preloaded amount of linear guide modulus in practical application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20stiffness" title="contact stiffness">contact stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=feeding%20stage" title=" feeding stage"> feeding stage</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20guides" title=" linear guides"> linear guides</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20characteristics" title=" modal characteristics"> modal characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-load" title=" pre-load"> pre-load</a> </p> <a href="https://publications.waset.org/abstracts/51628/variations-of-the-modal-characteristics-of-the-feeding-stage-with-different-preloaded-linear-guide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51628.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">430</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">2929</span> Assessing the Actions of the Farm Mangers to Execute Field Operations at Opportune Times</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Edwards">G.

However determining a field’s readiness is a difficult process that can involve large amounts of data and an experienced farm manager. A consequence of this is that operations are often executed when fields are unready, or partially unready, which can compromise results incurring environmental impacts, decreased yield and increased operational costs. In order to assess timeliness of operations’ execution, a new scheme is introduced to quantify the aptitude of farm managers to plan operations. Two criteria are presented by which the execution of operations can be evaluated as to their exploitation of a field’s readiness window. A dataset containing the execution dates of spring and autumn operations on 93 fields in Iowa, USA, over two years, was considered as an example and used to demonstrate how operations’ executions can be evaluated. The execution dates were compared with simulated data to gain a measure of how disparate the actual execution was from the ideal execution. The presented tool is able to evaluate the spring operations better than the autumn operations as required data was lacking to correctly parameterise the crop model. Further work is needed on the underlying models of the decision support tool in order for its situational knowledge to emulate reality more consistently. However the assessment methods and evaluation criteria presented offer a standard by which operations' execution proficiency can be quantified and could be used to identify farm managers who require decisional support when planning operations, or as a means of incentivising and promoting the use of sustainable farming practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=operation%20management" title="operation management">operation management</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20readiness" title=" field readiness"> field readiness</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20farming" title=" sustainable farming"> sustainable farming</a>, <a href="https://publications.waset.org/abstracts/search?q=workability" title=" workability"> workability</a> </p> <a href="https://publications.waset.org/abstracts/37757/assessing-the-actions-of-the-farm-mangers-to-execute-field-operations-at-opportune-times" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37757.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">387</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">2928</span> Failure Analysis of Low Relaxation Prestressed High Carbon Steel Wire During Drawing Operation: A Metallurgical Investigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Souvik%20Das">Souvik Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20%20Bhattacharya"> Sandip Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Mukhopadhyay"> Goutam Mukhopadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Manashi%20Adhikary"> Manashi Adhikary</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wires breakages during cold drawing are a complex phenomenon; wire breakages may be induced by improper wire-rod quality, inappropriate heat-treated microstructure, and/or lubrication breakdown on the wire surface. A comprehensive metallurgical investigation of failed/broken wire samples is therefore essential for understanding the origin of failure. Frequent breakage of wires during drawing is a matter of serious concern to the wire drawers as it erodes their already slim margins through reduced productivity and loss in yield. The present paper highlights the failure investigation of wires of Low Relaxation Prestressed High Carbon grade during cold drawing due to entrapment of hard constituents detached from the roller entry guide during rolling operations. The hardness measurement of this entrapped location indicates 54.9 Rockwell Hardness as against the rest portion 33.4 Rockwell Hardness. The microstructure chemical analysis and X-ray mapping analysis data of the entrapment location confirmed complex chromium carbide originated from D2-steel used in entry guide during the rolling process. Since the harder entrapped phase could not be deformed in the same manner as the parent phase, the failure of the wire rod occurs during hot rolling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LRPC" title="LRPC">LRPC</a>, <a href="https://publications.waset.org/abstracts/search?q=D2-steel" title=" D2-steel"> D2-steel</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium%20carbide" title=" chromium carbide"> chromium carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=roller%20guide" title=" roller guide"> roller guide</a> </p> <a href="https://publications.waset.org/abstracts/106416/failure-analysis-of-low-relaxation-prestressed-high-carbon-steel-wire-during-drawing-operation-a-metallurgical-investigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106416.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">2927</span> Pre- and Post-Analyses of Disruptive Quay Crane Scheduling Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20-H.%20Yang">K. -H.

There were a certain number of scheduling algorithms for quay crane operations, but without considering some nuisance factors that might disrupt the quay crane operations. For example, bad grapples make a crane unable to load or unload containers or a sudden strong breeze stops operations temporarily. Although these disruptive conditions randomly occur, they influence the efficiency of quay crane operations. The disruption is not considered in the operational procedures nor is evaluated in advance for its impacts. This study applies simulation and optimization approaches to develop structures of pre-analysis and post-analysis for the Quay Crane Scheduling Problem to deal with disruptive scenarios for quay crane operation. Numerical experiments are used for demonstrations for the validity of the developed approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disruptive%20quay%20crane%20scheduling" title="disruptive quay crane scheduling">disruptive quay crane scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-analysis" title=" pre-analysis"> pre-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=post-analysis" title=" post-analysis"> post-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=disruption" title=" disruption"> disruption</a> </p> <a href="https://publications.waset.org/abstracts/88036/pre-and-post-analyses-of-disruptive-quay-crane-scheduling-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88036.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">2926</span> The Effective Operations Competitive Advantages of Mobile Phone Service Providers across Countries: The Case of Middle East Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yazan%20Khalid%20Abed-Allah%20Migdadi">Yazan Khalid Abed-Allah Migdadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is identifying the effective operations competitive advantages of mobile phone service providers across countries.

Countering terrorism requires several measures that must be taken at the same time. Counterterrorism strategies of most countries depend on military measures. However, those strategies should also focus on nonlethal measures, such as economic, political, and social measures. The psychological dimensions of terrorism must be understood, evaluated, and used in countering terrorism. This study suggests that psychological operations, as nonlethal military operations, can be used to influence individuals not to join terrorist organizations and to facilitate defections from terrorist organizations. However, in order to implement effective psychological operations, one has to have appropriate intelligence about terrorist organizations. Examining terrorist organizations help us to identify their vulnerabilities and obtain this intelligence. This article concludes that terrorists’ motivations, terrorist organizations’ radicalization, recruitment, and conversion processes, ideology, goals, strategies, and general structure form the intelligence requirement for psychological operations in counterterrorism.

However, it takes many years to be able to use a tactile guide map without difficulty. Thus, information support, in which audio information is added in addition to tactile information, is required. In the present research, a method to prepare an in-school tactile guide map with an additional audio reading function was developed.

The tracheal introducer, known as the bougie guide, can aid ETI in patients with difficult airway pattern. Realistic simulation (RS) is a methodology utilized for healthcare professionals training. To improve skills in using the bougie guide of physicians from Recôncavo da Bahia region in Brazil, during COVID-19 outbreak, RS training was carried out. Simulated scenario included the Nasco Lifeform realistic simulator for ETI and a bougie guide introducer. Training was a capacitation program organized by the Health Department of Bahia State. Objective: To report effects in participants´ self-confidence perception for using bougie guide after a RS based training. Methods: Descriptive study, secondary data extracted from questionnaires. Priority workplace and previous knowledge about bougie were reported on a preparticipation formulary. Participants also completed pre- and post-training qualitative self-assessment (10-point Likert scale) regarding to self-confidence in using bougie guide. Distribution analysis for qualitative data was performed with Wilcoxon Signed Rank Test, and self-confidence increase analysis in frequency contingency tables with Fisher's exact test. Results: From May to June 2020 a total of 36 physicians participated of training, 25 (69%) from primary care setting, 32 (89%) with no previous knowledge about the bougie guide utilization. For those who had previous knowledge about bougie pre-training self-confidence median was 6,5, and 2 for participants who had not. In overall there was an increase in self-confidence median for bougie utilization. Median (variation) before and after training was 2.5 (1-7) vs. 8 (4-10) (p <0.0001). Among those who had no previous knowledge about bougie (n = 32) an increase in self-confidence greater than 3 points for bougie utilization was reported by 31 vs. 1 participants (p = 0.71). Conclusions: Most of participants had no previous knowledge about using the bougie guide. RS training contributed to self-confidence increase for using bougie for ETI procedure. RS methodology can contribute for training in using the bougie guide for ETI procedure during COVID-19 outbreak. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bougie" title="bougie">bougie</a>, <a href="https://publications.waset.org/abstracts/search?q=confidence" title=" confidence"> confidence</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=endotracheal%20intubation" title=" endotracheal intubation"> endotracheal intubation</a>, <a href="https://publications.waset.org/abstracts/search?q=realistic%20simulation" title=" realistic simulation"> realistic simulation</a> </p> <a href="https://publications.waset.org/abstracts/128757/report-of-a-realistic-simulation-training-in-using-bougie-guide-for-endotracheal-intubation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128757.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">144</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">2922</span> A Learning Effects Research Applied a Mobile Guide System with Augmented Reality for Education Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20L.%20Chang">Y.

The study included 96 college students as participants and employed a quasi-experimental research design. This study evaluated the learning performance of education center students aided with different guided modes, including their flow experience, activity involvement, learning effects, as well as their attitude and acceptance of using the guide systems. The results showed that (a) the AR guide promoted visitors’ flow experience; (b) the AR-guidance activity involvement and flow experience having a significant positive effect; (c) most of the visitors of mobile guide system with AR elicited a positive response and acceptance attitude. These results confirm the necessity of human–computer–context interaction.

This also addresses the competencies outlined in the curriculum guide while, at the same time, providing instructional material which the pupils can work on and practice solving word problems. The twelve randomly selected grade four pupils of Mantuyom Elementary School have been chosen as respondents for this action research in consideration of their consent and approval. A Pre-Test and a Post-test have been given to the pupils to determine their baseline proficiency level in four fundamental operations. The data has been statistically treated using a T-test to determine their difference. At a mean score of 13.42 and 16.83 for pre and post-tests, respectively, the p-value of 0.000620816 reflects a highly significant difference for the pre-test and post-test. This is lesser than the 0.05 level of significance (p≤0.05). Therefore, it is found that the compendium of contextualized story word problems is an efficient instructional material for Mathematics 4, yet; it is recommended that a Parents’ User Guide shall be developed to assist the parents in the conduct of the Remediation, Reinforcement and Enhancement (RRE). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=action%20research" title="action research">action research</a>, <a href="https://publications.waset.org/abstracts/search?q=compendium" title=" compendium"> compendium</a>, <a href="https://publications.waset.org/abstracts/search?q=contextualized" title=" contextualized"> contextualized</a>, <a href="https://publications.waset.org/abstracts/search?q=story" title=" story"> story</a>, <a href="https://publications.waset.org/abstracts/search?q=word%20problem" title=" word problem"> word problem</a>, <a href="https://publications.waset.org/abstracts/search?q=research" title=" research"> research</a>, <a href="https://publications.waset.org/abstracts/search?q=intervention" title=" intervention"> intervention</a> </p> <a href="https://publications.waset.org/abstracts/153628/utilization-of-the-compendium-on-contextualized-story-word-problems-in-mathematics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153628.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">98</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">2919</span> Principal Component Analysis Applied to the Electric Power Systems – Practical Guide; Practical Guide for Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Morales">John Morales</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Ordu%C3%B1a"> Eduardo Orduña</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently the Principal Component Analysis (PCA) theory has been used to develop algorithms regarding to Electric Power Systems (EPS).

The study determined the sequence that was more effective and mostly adopted by teachers of the operations. One hundred (100) teachers and sixty pupils (60) from primary one were used for the study. The pupils were divided into two equal groups. The researcher taught these operations to each group separately for four weeks (4 weeks). Group one was taught using the ASMD sequence, while group two was taught using ASMD sequence. In order to generate the needed data for the study, questionnaires and tests were administered on the samples. Data collected were analyzed and major findings were arrived at: (i) Two primary mathematics text books were used in all the primary schools in the area; (ii) Each of the textbooks contained the ASMD sequence; (iii) 73% of the teachers sampled adopted the ASMD sequence of teaching these operations; and (iv) Group one of the pupils (taught using AMSD sequence) performed significantly better than their counter parts in group two (taught using AMSD sequence). On the basis of this, the researcher concluded that the AMSD sequence was more effective in teaching the operations than the ASMD sequence. Consequently, the researcher concluded that primary schools teachers, authors of primary mathematics textbooks, and curriculum planner should adopt the AMSD sequence of teaching these operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=matematic" title="matematic">matematic</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20school" title=" high school"> high school</a>, <a href="https://publications.waset.org/abstracts/search?q=four%20basic%20operations" title=" four basic operations"> four basic operations</a>, <a href="https://publications.waset.org/abstracts/search?q=effectiveness%20of%20teaching" title=" effectiveness of teaching"> effectiveness of teaching</a> </p> <a href="https://publications.waset.org/abstracts/8847/comparing-the-sequence-and-effectiveness-of-teaching-the-four-basic-operations-and-mathematics-in-primary-schools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8847.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">253</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">2917</span> Digital Twin Smart Hospital: A Guide for Implementation and Improvements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enido%20Fabiano%20de%20Ramos">Enido Fabiano de Ramos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ieda%20Kanashiro%20Makiya"> Ieda Kanashiro Makiya</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20I.%20Giocondo%20Cesar"> Francisco I.

However, it is unclear what exploration and exploitation capabilities imply in improvement and development work within an operations context. So in order to better understand how to develop exploration and exploitation capabilities within operations, the main characteristics of these constructs needs to be identified and further understood. Thus, the objective of this research is to increase the understanding about exploitation and exploration characteristics, to concretize what they translates to within the context of improvement and development work in an operations unit, and to identify practical challenges. A literature review and a case study are presented. In the literature review, different interpretations of exploration and exploitation are portrayed, key characteristics have been identified, and a deepened understanding of exploration and exploitation characteristics is described. The case in the study is an operations unit, and the aim is to explore to what extent and in what ways exploration and exploitation activities are part of the improvement structures and processes. The contribution includes an identification of key characteristics of exploitation and exploration, as well as an interpretation of the constructs. Further, some practical challenges are identified. For instance, exploration activities tend to be given low priority, both in daily work as in the manufacturing strategy. Also, the overall understanding about the concepts of exploitation and exploration (or any similar aspect of dynamic improvement capabilities) is very low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exploitation" title="exploitation">exploitation</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration" title=" exploration"> exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement" title=" improvement"> improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20production" title=" lean production"> lean production</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title=" manufacturing"> manufacturing</a> </p> <a href="https://publications.waset.org/abstracts/32306/exploration-and-exploitation-within-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32306.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">487</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">2914</span> Multipurpose Agricultural Robot Platform: Conceptual Design of Control System Software for Autonomous Driving and Agricultural Operations Using Programmable Logic Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Abhishesh">P.

Based on given initial conditions by field analysis and desired agricultural operations, the structural design development of MARP is done using modelling and analysis tool. PLC, being robust and easy to use, has been used to design the autonomous control system of robot platform for desired parameters. The robot is capable of performing autonomous driving and three automatic agricultural operations, viz. hilling, mulching, and sowing of seeds in the respective order. The input received from various sensors on the field is later transmitted to the controller via ZigBee network to make the changes in the control program to get desired field output. The research is conducted to provide assistance to farmers by reducing labor hours for agricultural activities by implementing automation. This study will provide an alternative to the existing systems with machineries attached behind tractors and rigorous manual operations on agricultural field at effective cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20operations" title="agricultural operations">agricultural operations</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20driving" title=" autonomous driving"> autonomous driving</a>, <a href="https://publications.waset.org/abstracts/search?q=MARP" title=" MARP"> MARP</a>, <a href="https://publications.waset.org/abstracts/search?q=PLC" title=" PLC"> PLC</a> </p> <a href="https://publications.waset.org/abstracts/64269/multipurpose-agricultural-robot-platform-conceptual-design-of-control-system-software-for-autonomous-driving-and-agricultural-operations-using-programmable-logic-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64269.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">363</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">2913</span> Internal Leakage Analysis from Pd to Pc Port Direction in ECV Body Used in External Variable Type A/C Compressor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Iqbal%20Mahmud">M.

Method: The demographic, pre and post-operative treatment and implant characteristics were collected of all patients at Basildon hospital who underwent breast reconstruction from 2017-2023. We used the Breast-Q psychosocial well-being, physical well-being, and satisfaction with breasts scales. An Independent t-test was conducted for each group, and linear regression of age and implant size. Results: 69 patients were contacted, and 39 PROMs returned. The mean age of patients was 57.6. 40% had smoked before, and 40.8% had BMI>30. 29 had pre-pectoral placement, and 40 had subpectoral placement. 17 had smooth implants, and 52 textured. Sub pectoral placement was associated with higher (75.7 vs. 61.9 p=0.046) psychosocial scores than pre pectoral, and textured implants were associated with a lower physical score than the smooth surface (34.7 VS 50.2 P=0.046). On linear regression, age was positively associated (p=0.007) with psychosocial score. Conclusion: We present a large cohort of patients who underwent breast reconstruction. Understanding the PROMs of these procedures can guide clinicians, patients and policy makers to be more informed of the course of rehabilitation of these operations. Significance: We have found that from a patient perspective subpectoral implant placement was associated with a statistically significant improvement in psychosocial scores. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20surgery" title="breast surgery">breast surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=mastectomy" title=" mastectomy"> mastectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20implants" title=" breast implants"> breast implants</a>, <a href="https://publications.waset.org/abstracts/search?q=oncology" title=" oncology"> oncology</a> </p> <a href="https://publications.waset.org/abstracts/183040/patient-reported-outcome-measures-post-implant-based-reconstruction-basildon-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183040.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">61</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">2910</span> Regulation of the Commercial Credits in the Foreign Exchange Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marija%20Vicic">Marija Vicic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of commercial credit regulation in an unified way under Law on Foreign Exchange Operations in Republic of Serbia allows an easier state monitoring of credit operations performed by non-professionals on foreign exchange market. By broadly defining the term “commercial credits“, the state (i.e. National Bank of Serbia) is given the authority to monitor the performance of all obligations under commercial contracts in which the obligations are not performed simultaneously. In the first part of the paper, the author analyses the economic gist of commercial credits with the purpose of giving an insight into their special treatment. The author examines the term „commercial credits“ given in Law on foreign exchange operations and the difference between financial credits and irregular commercial credits (exports and imports of goods and services deemed to be commercial credits) is particularly highlighted. In the second part, the author emphasizes the specifics of commercial credit contracts, especially the effects of special requests for the parties to these contracts to notify National Bank of Serbia and specific regulations regarding maturity of obligations under these commercial credits and the assignment and compensation of the said contracts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commercial%20credit" title="commercial credit">commercial credit</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20exchange%20operations" title=" foreign exchange operations"> foreign exchange operations</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20transactions" title=" commercial transactions"> commercial transactions</a>, <a href="https://publications.waset.org/abstracts/search?q=deferred%20payment" title=" deferred payment"> deferred payment</a>, <a href="https://publications.waset.org/abstracts/search?q=advance%20payment" title=" advance payment"> advance payment</a>, <a href="https://publications.waset.org/abstracts/search?q=%28non%29%20resident" title=" (non) resident"> (non) resident</a> </p> <a href="https://publications.waset.org/abstracts/27991/regulation-of-the-commercial-credits-in-the-foreign-exchange-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27991.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">421</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">2909</span> Tribological Behavior of PTFE Composites Used for Guide Rings of Hydraulic Actuating Cylinders under Oil-Lubricated Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trabelsi%20Mohamed">Trabelsi Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Kharrat%20Mohamed"> Kharrat Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Dammak%20Maher"> Dammak Maher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Guide rings play an important role in the performance and durability of hydraulic actuating cylinders. In service, guide rings surfaces are subjected to friction and wear against steel counterface. A good mastery of these phenomena is required for the improvement of the energy safeguard and the durability of the actuating cylinder. Polytetrafluoroethylene (PTFE) polymer is extensively used in guide rings thanks to its low coefficient of friction, its good resistance to solvents as well as its high temperature stability. In this study, friction and wear behavior of two PTFE composites filled with bronze and bronze plus MoS2 were evaluated under oil-lubricated condition, aiming as guide rings for hydraulic actuating cylinder. Wear tests of the PTFE composite specimen sliding against steel ball were conducted using reciprocating linear tribometer. The wear mechanisms of the composites under the same sliding condition were discussed, based on Scanning Electron Microscopy examination of the worn composite surface and the optical micrographs of the steel counter surface. As for the results, comparative friction behaviors of the PTFE composites and lower friction coefficients were recorded under oil lubricated condition. The wear behavior was considerably improved to compare with this in dry sliding, while the oil adsorbed layer limited the transfer of the PTFE to the steel counter face during the sliding test. <p
