This expansion of work duties to non-work time challenges their work-life balance. However, there has been inconsistency in the results on how these relationships correlate. This, therefore, calls for further research studies to examine the moderating mechanisms of such relationships. The present study, therefore, ascertained how vocational and technical educators’ technology acceptance relates to their work-related ICT use beyond their working hours and work-life balance, as well as how their integration affects these relationships. The population of the study comprised 320 Vocational and Technical Educators from the Southeast geopolitical zone of Nigeria. Data were collected from the respondents using the structured questionnaire. The questionnaire was validated by three experts. The reliability of the study was conducted using 20 vocational and technical educators from the South who were not part of the population. The overall reliability coefficient of 0.81 was established using Cronbach’s alpha method. The data collected was analyzed using Structural equation modeling. Findings, among others, revealed that vocational and technical educators’ work-life balance was mediated by increased digital learning environment use after work hours, although reduced by social influence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vocational%20and%20technical%20educators" title="vocational and technical educators">vocational and technical educators</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20learning%20environment" title=" digital learning environment"> digital learning environment</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20hours" title=" working hours"> working hours</a>, <a href="https://publications.waset.org/abstracts/search?q=work-life%20balance" title=" work-life balance"> work-life balance</a>, <a href="https://publications.waset.org/abstracts/search?q=integration%20preference" title=" integration preference"> integration preference</a> </p> <a href="https://publications.waset.org/abstracts/182690/vocational-and-technical-educators-acceptance-and-use-of-digital-learning-environments-beyond-working-hours-implications-for-work-life-balance-and-the-role-of-integration-preference" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182690.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">67</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">12330</span> Investigation of Operational Conditions for Treatment of Industrial Wastewater Contaminated with Pesticides Using Electro-Fenton Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Gar%20Alalm">Mohamed Gar Alalm</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to investigate various operating conditions that affect the performance of the electro-Fenton process for degradation of pesticides.

Given the challenges and technical limitations of experimental studies for accurate interface temperature sensing, complex manufacturing process, and short duration of membranes, a dimensionless lattice Boltzmann method capable of restoring thermophysical properties of working fluid is particularly derived. The evaporation of R134a to its pure vapour ambient in nanoporous membranes with the pore diameter of 80nm, thickness of 472nm, and three porosities of 0.25, 0.33 and 0.5 are numerically simulated. The numerical results indicate that the highest heat transfer coefficient is about 1740kW/m²·K; the highest heat flux is about 1.49kW/cm² with only about the wall superheat of 8.59K in the case of porosity equals to 0.5. The dissipated heat flux scaled with porosity because of the increasing effective evaporative area. Additionally, the self-regulation of the shape and curvature of the meniscus under different operating conditions is also observed. This work shows a promising approach to forecast the membrane performance for different geometry and working fluids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20heat%20flux" title="high heat flux">high heat flux</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrathin%20nanoporous%20membrane" title=" ultrathin nanoporous membrane"> ultrathin nanoporous membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film%20evaporation" title=" thin film evaporation"> thin film evaporation</a>, <a href="https://publications.waset.org/abstracts/search?q=lattice%20Boltzmann%20method" title=" lattice Boltzmann method"> lattice Boltzmann method</a> </p> <a href="https://publications.waset.org/abstracts/127523/investigation-on-ultrahigh-heat-flux-of-nanoporous-membrane-evaporation-using-dimensionless-lattice-boltzmann-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127523.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">162</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">12327</span> Correlation to Predict Thermal Performance According to Working Fluids of Vertical Closed-Loop Pulsating Heat Pipe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niti%20Kammuang-lue">Niti Kammuang-lue</a>, <a href="https://publications.waset.org/abstracts/search?q=Kritsada%20On-ai"> Kritsada On-ai</a>, <a href="https://publications.waset.org/abstracts/search?q=Phrut%20Sakulchangsatjatai"> Phrut Sakulchangsatjatai</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradit%20Terdtoon"> Pradit Terdtoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objectives of this paper are to investigate effects of dimensionless numbers on thermal performance of the vertical closed-loop pulsating heat pipe (VCLPHP) and to establish a correlation to predict the thermal performance of the VCLPHP. The CLPHPs were made of long copper capillary tubes with inner diameters of 1.50, 1.78, and 2.16mm and bent into 26 turns. Then, both ends were connected together to form a loop. The evaporator, adiabatic, and condenser sections length were equal to 50 and 150 mm. R123, R141b, acetone, ethanol, and water were chosen as variable working fluids with constant filling ratio of 50% by total volume. Inlet temperature of heating medium and adiabatic section temperature was constantly controlled at 80 and 50oC, respectively. Thermal performance was represented in a term of Kutateladze number (Ku). It can be concluded that when Prandtl number of liquid working fluid (Prl), and Karman number (Ka) increases, thermal performance increases. On contrary, when Bond number (Bo), Jacob number (Ja), and Aspect ratio (Le/Di) increases, thermal performance decreases. Moreover, the correlation to predict more precise thermal performance has been successfully established by analyzing on all dimensionless numbers that have effect on the thermal performance of the VCLPHP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vertical%20closed-loop%20pulsating%20heat%20pipe" title="vertical closed-loop pulsating heat pipe">vertical closed-loop pulsating heat pipe</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20fluid" title=" working fluid"> working fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20performance" title=" thermal performance"> thermal performance</a>, <a href="https://publications.waset.org/abstracts/search?q=dimensionless%20parameter" title=" dimensionless parameter"> dimensionless parameter</a> </p> <a href="https://publications.waset.org/abstracts/4883/correlation-to-predict-thermal-performance-according-to-working-fluids-of-vertical-closed-loop-pulsating-heat-pipe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4883.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">414</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">12326</span> Modeling and Prediction of Hot Deformation Behavior of IN718</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Azarbarmas">M.

A sample of grade 1 educators were selected for the study. The sample comprised of twelve grades 1 educators from four local schools in the Western Cape. All twelve educators were individually interviewed and discussed the management strategies used in the classroom when working with learner presenting with ADHD symptoms. The data was analysed qualitatively with a focus in identifying, sorting and analyse meaning according to the subjective perception, understanding and behaviour of the grade 1 educators within their context. Furthermore, the social, cultural, political and physical environment of the participants were taken into consideration to explore and interpret the link between these elements. The findings were as follows: many educators felt that they did not receive enough training on Attention Deficit Hyperactivity Disorder, therefore lacking knowledge on how to apply management strategies to address this. Managing a diverse range of learners, lack of resources, lack of parental involvement, lack of assistance in the classroom, as well as distracted and disorganised children posed as challenges for educators working with learners presenting with Attention Deficit Hyperactivity Disorder symptoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ADHD" title="ADHD">ADHD</a>, <a href="https://publications.waset.org/abstracts/search?q=Grade%201%20educators" title=" Grade 1 educators"> Grade 1 educators</a>, <a href="https://publications.waset.org/abstracts/search?q=Learners" title=" Learners"> Learners</a>, <a href="https://publications.waset.org/abstracts/search?q=Management%20strategies" title=" Management strategies"> Management strategies</a> </p> <a href="https://publications.waset.org/abstracts/91557/exploring-management-strategies-used-by-grade-1-educators-in-the-classroom-working-with-learners-presenting-with-adhd-symptoms-in-the-western-cape" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91557.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">209</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">12322</span> Parameter and Lose Effect Analysis of Beta Stirling Cycle Refrigerating Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muluken%20Z.%20Getie">Muluken Z.

First, the developed numerical model incorporates into the ideal adiabatic analysis, the shuttle heat transfer (heat loss from compression space to expansion space), and gas leakage from the working space to the buffer space into the crankcase. The other losses that may not have a direct effect on the temperature and pressure of working fluid are simply incorporated in a simple analysis. The model is then validated by reversing the model to the engine model and compared with other literature results using (GPU-3) engine. After validating the model with other engine model and experiment results, analysis of the effect of phase angle, shuttle heat lose and gas leakage on temperature, pressure, and performance (power requirement, cooling capacity and coefficient of performance) of refrigerating machine considering the FEMTO 60 Stirling engine as a case study have been conducted. Shuttle heat loss has a greater effect on the temperature of working gas; gas leakage to the crankcase has more effect on the pressure of working spaces and hence both have a considerable impact on the performance of the Stirling cycle refrigerating machine. The optimum coefficient of performance exists between phase angles of 900-950, and optimum cooling capacity could be found between phase angles of 950-980. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta%20configuration" title="beta configuration">beta configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20model" title=" engine model"> engine model</a>, <a href="https://publications.waset.org/abstracts/search?q=moderate%20cooling" title=" moderate cooling"> moderate cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=stirling%20refrigerator" title=" stirling refrigerator"> stirling refrigerator</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20validation" title=" and validation"> and validation</a> </p> <a href="https://publications.waset.org/abstracts/120316/parameter-and-lose-effect-analysis-of-beta-stirling-cycle-refrigerating-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120316.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12321</span> Numerical Investigations of Unstable Pressure Fluctuations Behavior in a Side Channel Pump</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Desmond%20Appiah">Desmond Appiah</a>, <a href="https://publications.waset.org/abstracts/search?q=Fan%20Zhang"> Fan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shouqi%20Yuan"> Shouqi Yuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Xueyuan"> Wei Xueyuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20N.%20Asomani"> Stephen N. Asomani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The side channel pump has distinctive hydraulic performance characteristics over other vane pumps because of its generation of high pressure heads in only one impeller revolution. Hence, there is soaring utilization and application in the fields of petrochemical, food processing fields, automotive and aerospace fuel pumping where high heads are required at low flows. The side channel pump is characterized by unstable flow because after fluid flows into the impeller passage, it moves into the side channel and comes back to the impeller again and then moves to the next circulation. Consequently, the flow leaves the side channel pump following a helical path. However, the pressure fluctuation exhibited in the flow greatly contributes to the unwanted noise and vibration which is associated with the flow. In this paper, a side channel pump prototype was examined thoroughly through numerical calculations based on SST k-ω turbulence model to ascertain the pressure fluctuation behavior. The pressure fluctuation intensity of the 3D unstable flow dynamics were carefully investigated under different working conditions 0.8QBEP, 1.0 QBEP and 1.2QBEP. The results showed that the pressure fluctuation distribution around the pressure side of the blade is greater than the suction side at the impeller and side channel interface (z=0) for all three operating conditions. Part-load condition 0.8QBEP recorded the highest pressure fluctuation distribution because of the high circulation velocity thus causing an intense exchanged flow between the impeller and side channel. Time and frequency domains spectra of the pressure fluctuation patterns in the impeller and the side channel were also analyzed under the best efficiency point value, QBEP using the solution from the numerical calculations. It was observed from the time-domain analysis that the pressure fluctuation characteristics in the impeller flow passage increased steadily until the flow reached the interrupter which separates low-pressure at the inflow from high pressure at the outflow. The pressure fluctuation amplitudes in the frequency domain spectrum at the different monitoring points depicted a gentle decreasing trend of the pressure amplitudes which was common among the operating conditions. The frequency domain also revealed that the main excitation frequencies occurred at 600Hz, 1200Hz, and 1800Hz and continued in the integers of the rotating shaft frequency. Also, the mass flow exchange plots indicated that the side channel pump is characterized with many vortex flows. Operating conditions 0.8QBEP, 1.0 QBEP depicted less and similar vortex flow while 1.2Q recorded many vortex flows around the inflow, middle and outflow regions. The results of the numerical calculations were finally verified experimentally. The performance characteristics curves from the simulated results showed that 0.8QBEP working condition recorded a head increase of 43.03% and efficiency decrease of 6.73% compared to 1.0QBEP. It can be concluded that for industrial applications where the high heads are mostly required, the side channel pump can be designed to operate at part-load conditions. This paper can serve as a source of information in order to optimize a reliable performance and widen the applications of the side channel pumps. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exchanged%20flow" title="exchanged flow">exchanged flow</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20fluctuation" title=" pressure fluctuation"> pressure fluctuation</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=side%20channel%20pump" title=" side channel pump"> side channel pump</a> </p> <a href="https://publications.waset.org/abstracts/91948/numerical-investigations-of-unstable-pressure-fluctuations-behavior-in-a-side-channel-pump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91948.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">136</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">12320</span> Experimental Study of the Modifications of the Bed of a River under Extreme Flow Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Ghenaim">A.

Such aspiration meets with reality when the destined parent is able to give adequate supports and services to his/her children, whether the latter are got by birth or through adoption. The adequacy of services parents provide their children is both enriched and tempted by the work on which they involve. On the one hand, parents need to work and earn a living in order to support their family. On the other hand, they must spend most of their time outside home to do the work, which shortens the time and might they spare to care for their children. Where the sufficiency of services parents owe their children could be ascertained by in terms of life skills, physical care and related provisions, the role of working fathers and mothers in providing such supports could be diverse across cultures and work traditions. Hence, this research deals with the investigation of working mothers’ parental practices, challenges they face in providing parental services and the implication for the future progress of the parents and their children. Target of the study will be Arsi University in Oromia Regional State of Ethiopia. Descriptive survey design in holding the research, and data for the research will be collected in the form of experiential self-report from 150 working mothers selected from the entire working women population of Colleges of Agriculture and Environmental Studies and College of Health Sciences through stratified random-sampling. Instruments of data collection will be closed and open-ended questionnaire. Complementary data will also be collected from purposively selected samples through semi-structured interview. Data for the research will be collected through questionnaire first and then through interview. Data analysis will also follow the same procedure. The collected data will systematically be organized and statistically and thematically analyzed in order to come up with indicative findings. The overarching thesis is that, working mothers in the study area bear a lot of responsibilities both at home and at work place which leave them very little time for parenting services. Unless due attention is given to the way they can spare time for their children, they are more likely to be tense between work-life and family care services, which tempt them in different directions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=challenges" title="challenges">challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=mothers" title=" mothers"> mothers</a>, <a href="https://publications.waset.org/abstracts/search?q=practices" title=" practices"> practices</a>, <a href="https://publications.waset.org/abstracts/search?q=university" title=" university"> university</a>, <a href="https://publications.waset.org/abstracts/search?q=working" title=" working"> working</a> </p> <a href="https://publications.waset.org/abstracts/59318/parenting-practices-challenges-and-prospectus-of-working-mothers-in-arsi-university-oromia-regional-state-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59318.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">300</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">12318</span> Performance Analysis of Air Conditioning System Working on the Vapour Compression Refrigeration Cycle under Magnetohydrodynamic Influence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikhil%20S.%20Mane">Nikhil S.

The use of magnetohydrodynamic (MHD) forces in power generation and mass transfer is increasing steadily but its application to enhance the convective currents in fluids needed to be explored. The enhancement in convective heat transfer using MHD forces can be employed in heat exchangers, cooling of molten metal, vapour compression refrigeration (VCR) systems etc. The effective increase in the convective heat transfer without any additional energy consumption will lead to the energy efficient heat exchanging devices. In this work, the effect of MHD forces on the performance of air conditioning system working on the VCR system is studied. The refrigerant in VCR system is exposed to the magnetic field which influenced the flow of refrigerant. The different intensities of magnets are used on the different liquid refrigerants and investigation on performance of split air conditioning system is done under different loading conditions. The results of this research work show that the application of magnet on refrigerant flow has positive influence on the coefficient of performance (COP) of split air conditioning system. It is also observed that with increasing intensity of magnetic force the COP of split air conditioning system also increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamics" title="magnetohydrodynamics">magnetohydrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer%20enhancement" title=" heat transfer enhancement"> heat transfer enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=VCRS" title=" VCRS"> VCRS</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning" title=" air conditioning"> air conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigeration" title=" refrigeration"> refrigeration</a> </p> <a href="https://publications.waset.org/abstracts/81030/performance-analysis-of-air-conditioning-system-working-on-the-vapour-compression-refrigeration-cycle-under-magnetohydrodynamic-influence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81030.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">212</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">12317</span> Assisted Approach as a Tool for Increasing Attention When Using the iPad in a Special Elementary School: Action Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vojt%C4%9Bch%20Gybas">Vojtěch Gybas</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Klubal"> Libor Klubal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kate%C5%99ina%20Kostol%C3%A1nyov%C3%A1"> Kateřina Kostolányová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, mobile touch technologies, such as tablets, are an integral part of teaching and learning in many special elementary schools. Many special education teachers tend to choose an iPad tablet with iOS. The reason is simple; the iPad has a function for pupils with special educational needs. If we decide to use tablets in teaching, in general, first we should try to stimulate the cognitive abilities of the pupil at the highest level, while holding the pupil’s attention on the task, when working with the device. This paper will describe how student attention can be increased by eliminating the working environment of selected applications, while using iPads with pupils in a special elementary school. Assisted function approach is highly effective at eliminating unwanted touching by a pupil when working on the desktop iPad, thus actively increasing the pupil´s attention while working on specific educational applications. During the various stages of the action, the research was conducted via data collection and interpretation. After a phase of gaining results and ideas for practice and actions, we carried out the check measurement, this time using the tool-assisted approach. In both cases, the pupils worked in the Math Board application and the resulting differences were evident. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=special%20elementary%20school" title="special elementary school">special elementary school</a>, <a href="https://publications.waset.org/abstracts/search?q=a%20mobile%20touch%20device" title=" a mobile touch device"> a mobile touch device</a>, <a href="https://publications.waset.org/abstracts/search?q=iPad" title=" iPad"> iPad</a>, <a href="https://publications.waset.org/abstracts/search?q=attention" title=" attention"> attention</a>, <a href="https://publications.waset.org/abstracts/search?q=Math%20Board" title=" Math Board"> Math Board</a> </p> <a href="https://publications.waset.org/abstracts/60753/assisted-approach-as-a-tool-for-increasing-attention-when-using-the-ipad-in-a-special-elementary-school-action-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60753.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">254</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">12316</span> Stabilizing a Failed Slope in Islamabad, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Umer%20Zubair">Muhammad Umer Zubair</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamran%20Akhtar"> Kamran Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Arsalan%20Khan"> Muhammad Arsalan Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is based on a research carried out on a failed slope in Defence Housing Authority (DHA) Phase I, Islamabad.

Yet 40% of the 65–74-year-olds do not use the Internet at all, and digital divide between young and elderly people's use of ICT is larger than in many advanced countries. Poor access to ICT resource and insufficient digital skills can lead to detachment from digital health resources, delayed diagnoses, and increased rates of hospitalization. To reveal digital divide within the elderly population itself, the presentation focuses on the health information behavior of Estonian seniors who either continue or have stopped working after retirement to use digital health applications. The author's main interest is on access, trust, and skills to use the Internet for medical purposes. Fifteen in-depth interviews with 65+ working persons, as well as 15 interviews with full-time retirees, were conducted. Also, six think-aloud protocols were conducted. The results indicate that older adults, who due to the nature of their work, have regular access to computers, often search for health-related information online. They exposed high source criticism and were successful in solving the given tasks. Conversely, most of the fully retired older adults claimed not using computers or other digital devices and cited lack of skills as the main reason for their inactivity. Thus, when developing health applications, it should be borne in mind that the ability and willingness of older adults to use e-solutions are very different. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20divide" title="digital divide">digital divide</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20healthcare" title=" digital healthcare"> digital healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20information%20behavior" title=" health information behavior"> health information behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=older%20adults" title=" older adults"> older adults</a> </p> <a href="https://publications.waset.org/abstracts/125383/readiness-of-estonian-working-and-non-working-older-adults-to-benefit-from-ehealth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125383.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">153</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">12313</span> Numerical Investigation of the Effect of the Spark Plug Gap on Engine-Like Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20Pinheiro%20Martins">Fernanda Pinheiro Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Teixeira%20Lacava"> Pedro Teixeira Lacava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this research is to analyze the effects of different spark plug conditions in engine-like conditions by applying computational fluid dynamics analysis.

The random variations in the measured intensity of solar irradiance are due to clouds and, in the case of arid regions, dust storms which decrease the intensity of intensity of solar irradiance. Therefore, modeling PV power output using average, maximum, or minimum solar irradiance values is inefficient to predict power generation reliably. The overall objective of this paper is to predict the power output of PV modules using Monte Carlo approach based the weather and solar conditions measured in Kuwait. Given the 250 Wp PV module used in study, the average daily power output is 1021 Wh/day. The maximum power was generated in April and the minimum power was generated in January 1187 Wh/day and 823 Wh/day respectively. The certainty of the daily predictions varies seasonally and according to the weather conditions. The output predictions were far more certain in the summer months, for example, the 80% certainty range for August is 89 Wh/day, whereas the 80% certainty range for April is 250 Wh/day. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo" title="Monte Carlo">Monte Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20renewable%20energy" title=" variable renewable energy"> variable renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait" title=" Kuwait"> Kuwait</a> </p> <a href="https://publications.waset.org/abstracts/99078/working-title-estimating-the-power-output-of-photovoltaics-in-kuwait-using-a-monte-carlo-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99078.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">131</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">12311</span> An Educational Application of Online Games for Learning Difficulties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Margoudi">Maria Margoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zacharoula%20Smyraniou"> Zacharoula Smyraniou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current paper presents the results of a conducted case study, which was part of the author’s master thesis. During the past few years the number of children diagnosed with Learning Difficulties has drastically augmented and especially the cases of ADHD (Attention Deficit Hyperactivity Disorder). One of the core characteristics of ADHD is a deficit in working memory functions. The review of the literature indicates a plethora of educational software that aim at training and enhancing the working memory. Nevertheless, in the current paper, the possibility of using for the same purpose free, online games will be explored. Another issue of interest is the potential effect of the working memory training to the core symptoms of ADHD. In order to explore the abovementioned research questions, three digital tests are employed, all of which are developed on the E-slate platform by the author, in order to check the level of ADHD’s symptoms and to be used as diagnostic tools, both in the beginning and in the end of the case study. The tools used during the main intervention of the research are free online games for the training of working memory. The research and the data analysis focus on the following axes: a) the presence and the possible change in two of the core symptoms of ADHD, attention and impulsivity and b) a possible change in the general cognitive abilities of the individual. The case study was conducted with the participation of a thirteen year-old, female student, diagnosed with ADHD, during after-school hours. The results of the study indicate positive changes both in the levels of attention and impulsivity. Therefore we conclude that the training of working memory through the use of free, online games has a positive impact on the characteristics of ADHD. Finally, concerning the second research question, the change in general cognitive abilities, no significant changes were noted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ADHD" title="ADHD">ADHD</a>, <a href="https://publications.waset.org/abstracts/search?q=attention" title=" attention"> attention</a>, <a href="https://publications.waset.org/abstracts/search?q=impulsivity" title=" impulsivity"> impulsivity</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20games" title=" online games"> online games</a> </p> <a href="https://publications.waset.org/abstracts/33683/an-educational-application-of-online-games-for-learning-difficulties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33683.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">358</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">12310</span> The Views of Teachers over the Father Involvement to Preschool Education Programs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Tezel%20Sahin">Fatma Tezel Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Nur%20Aydin%20Kilic"> Zeynep Nur Aydin Kilic</a>, <a href="https://publications.waset.org/abstracts/search?q=Aysegul%20Akinci%20Cosgun"> Aysegul Akinci Cosgun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Family involvement activities are a significant place in increasing the success in preschool education and maintaining the education. It is necessary that both of the parents be in the family involvement activities. However, while mother involvement is obtained in the family involvement activities, father involvement is neglected. For that reason, the current study aims at determining the views of teachers with regard to father involvement in the preschool education programs. The working group of the study consisted of 23 preschool teachers. The study is a descriptive survey. The data were obtained through individual interviews. As a data collection instrument, “Teacher Interview Form” was used. The data were analysed through content analysis method. The data regarding the views of the teachers were given as frequency and percentage values. At the end of the research, a great majority of the teachers stated that they were proficient in applying family involvement studies. They also pointed out that they held more family meetings in order to obtain family involvement and then they implemented involvement activities both in the class and out of the class for parents. They expressed that they observed more mother involvement in these activities that fathers. Parents expressed that the reasons why fathers involved in these activities less compared to mothers were the working conditions of fathers and that it was regarded as a task of mothers. Depending on the results of the research, it is likely to recommend that fathers should be informed about the involvement in family activities and that some applications and opportunities should be supplied for the fathers in preschool education institutions in order to encourage them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=preschool%20education" title="preschool education">preschool education</a>, <a href="https://publications.waset.org/abstracts/search?q=parent%20involvement" title=" parent involvement"> parent involvement</a>, <a href="https://publications.waset.org/abstracts/search?q=father%20involvement" title=" father involvement"> father involvement</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20views" title=" teacher views "> teacher views </a> </p> <a href="https://publications.waset.org/abstracts/61826/the-views-of-teachers-over-the-father-involvement-to-preschool-education-programs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61826.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">324</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">12309</span> Uni-Mode Uniqueness Conditions for Candecomp/Parafac of N-Way Arrays with Linearly Dependent Loadings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ling%20Zhang">Ling Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weikai%20Li"> Weikai Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently three sufficient conditions for the three-way Candecomp/Parafac (CP) model which ensure uniqueness in one of the three modes(“uni-mode uniqueness”) are given.

The youths of today irrespective of their gender need to acquire the knowledge, skills and attitudes that will enable them to create or find jobs as well as cope with unpredictable labour market changes throughout their working lives. In a study carried out to determine the influence of gender on job-competencies requirements of chemical-based industries and undergraduate-competencies acquisition by chemists working in the industries, all chemistry graduates working in twenty (20) chemical-based industries that were randomly selected from six sectors of chemical-based industries in Lagos and Ogun States of Nigeria were administered with Job-competencies required and undergraduate-competencies acquired assessment questionnaire. The data were analysed using means and independent sample t-test. The findings revealed that the population of female chemists working in chemical-based industries is low compared with the number of male chemists; furthermore, job-competencies requirements are found not to be gender sensitive while there is no significant difference in undergraduate-competencies acquisition of male and female chemists. This suggests that females should be given the same opportunity of employment in chemical-based industries as their male counterparts. The study also revealed the level of acquisition of undergraduate competencies as related to the needs of chemical-based industries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge" title="knowledge">knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=skill" title=" skill"> skill</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=acquired" title=" acquired"> acquired</a>, <a href="https://publications.waset.org/abstracts/search?q=required" title=" required"> required</a>, <a href="https://publications.waset.org/abstracts/search?q=employability" title=" employability"> employability</a> </p> <a href="https://publications.waset.org/abstracts/21145/the-influence-of-gender-on-job-competencies-requirements-of-chemical-based-industries-and-undergraduate-competencies-acquisition-of-chemists-in-south-west-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21145.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">379</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">12306</span> The Response to Various Planting Conditions of Thein Corn Inbred Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Boonlertnirun">K.

The results showed that no interaction between inbred line and planting condition in terms of yield. Correlation between planting conditions based on yield of inbred line was positive at medium level. Thein corn inbreds, namely L7, L5, L16, and L14 lines were tolerant to low nitrogen condition because they could produce high yield under all planting conditions and they were selected to be germ plasm for further breeding program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inbred%20line" title="inbred line">inbred line</a>, <a href="https://publications.waset.org/abstracts/search?q=planting%20condition" title=" planting condition"> planting condition</a>, <a href="https://publications.waset.org/abstracts/search?q=Thein%20corn" title=" Thein corn"> Thein corn</a>, <a href="https://publications.waset.org/abstracts/search?q=planting%20conditions" title=" planting conditions"> planting conditions</a> </p> <a href="https://publications.waset.org/abstracts/2298/the-response-to-various-planting-conditions-of-thein-corn-inbred-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2298.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">372</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">12305</span> Intensive Use of Software in Teaching and Learning Calculus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nodelman%20V.">Nodelman V.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite serious difficulties in the assimilation of the conceptual system of Calculus, software in the educational process is used only occasionally, and even then, mainly for illustration purposes. The following are a few reasons: The non-trivial nature of the studied material, Lack of skills in working with software, Fear of losing time working with software, The variety of the software itself, the corresponding interface, syntax, and the methods of working with the software, The need to find suitable models, and familiarize yourself with working with them, Incomplete compatibility of the found models with the content and teaching methods of the studied material. This paper proposes an active use of the developed non-commercial software VusuMatica, which allows removing these restrictions through Broad support for the studied mathematical material (and not only Calculus). As a result - no need to select the right software, Emphasizing the unity of mathematics, its intrasubject and interdisciplinary relations, User-friendly interface, Absence of special syntax in defining mathematical objects, Ease of building models of the studied material and manipulating them, Unlimited flexibility of models thanks to the ability to redefine objects, which allows exploring objects characteristics, and considering examples and counterexamples of the concepts under study. The construction of models is based on an original approach to the analysis of the structure of the studied concepts. Thanks to the ease of construction, students are able not only to use ready-made models but also to create them on their own and explore the material studied with their help. The presentation includes examples of using VusuMatica in studying the concepts of limit and continuity of a function, its derivative, and integral. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=counterexamples" title="counterexamples">counterexamples</a>, <a href="https://publications.waset.org/abstracts/search?q=limitations%20and%20requirements" title=" limitations and requirements"> limitations and requirements</a>, <a href="https://publications.waset.org/abstracts/search?q=software" title=" software"> software</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20learning%20calculus" title=" teaching and learning calculus"> teaching and learning calculus</a>, <a href="https://publications.waset.org/abstracts/search?q=user-friendly%20interface%20and%20syntax" title=" user-friendly interface and syntax"> user-friendly interface and syntax</a> </p> <a href="https://publications.waset.org/abstracts/159150/intensive-use-of-software-in-teaching-and-learning-calculus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159150.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">81</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">12304</span> Manual Pit Emptiers and Their Heath: Profiles, Determinants and Interventions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivy%20Chumo">Ivy Chumo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheillah%20Simiyu"> Sheillah Simiyu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hellen%20Gitau"> Hellen Gitau</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Kisiangani"> Isaac Kisiangani</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Kabaria%20Kanyiva%20Muindi"> Caroline Kabaria Kanyiva Muindi</a>, <a href="https://publications.waset.org/abstracts/search?q=Blessing%20Mberu"> Blessing Mberu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global sanitation workforce bridges the gap between sanitation infrastructure and the provision of sanitation services through essential public service work. Manual pit emptiers often perform the work at the cost of their dignity, safety, and health as their work requires repeated heavy physical activities such as lifting, carrying, pulling, and pushing. This exposes them to occupational and environmental health hazards and risking illness, injury, and death. The study will extend the studies by presenting occupational health risks and suggestions for improvement in informal settlements of Nairobi, Kenya. This is a qualitative study conducted among sanitation stakeholders in Korogocho, Mukuru and Kibera informal settlements in Nairobi. Data were captured using digital voice recorders, transcribed and thematically analysed. The discussion notes were further supported by observational notes made during the interviews. These formed the basis for a robust picture of occupational health of manual pit emptiers; a lack or inappropriate use of protective clothing, and prolonged duration of working hours were described to contribute to the occupational health hazard. To continue working, manual pit emptiers had devised coping strategies which include working in groups, improvised protective clothing, sharing the available protective clothing, working at night and consuming alcohol drinks while at work. Many of these strategies are detrimental to their health. Occupational health hazards among pit emptiers are key for effective working and is as a result of a lack of collaboration amongst stakeholders linked to health, safety and lack of PPE of pit emptiers. Collaborations amongst sanitation stakeholders is paramount for health, safety, and in ensuring the provision and use of personal protective devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sanitation" title="sanitation">sanitation</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health" title=" occupational health"> occupational health</a>, <a href="https://publications.waset.org/abstracts/search?q=manual%20emptiers" title=" manual emptiers"> manual emptiers</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20settlements" title=" informal settlements"> informal settlements</a> </p> <a href="https://publications.waset.org/abstracts/134217/manual-pit-emptiers-and-their-heath-profiles-determinants-and-interventions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134217.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">199</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">12303</span> Improving Working Memory in School Children through Chess Training</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Veena%20Easvaradoss">Veena Easvaradoss</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebenezer%20Joseph"> Ebenezer Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumathi%20Chandrasekaran"> Sumathi Chandrasekaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Sweta%20Jain"> Sweta Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Aparna%20Anna%20Mathai"> Aparna Anna Mathai</a>, <a href="https://publications.waset.org/abstracts/search?q=Senta%20Christy"> Senta Christy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Working memory refers to a cognitive processing space where information is received, managed, transformed, and briefly stored. It is an operational process of transforming information for the execution of cognitive tasks in different and new ways. Many class room activities require children to remember information and mentally manipulate it. While the impact of chess training on intelligence and academic performance has been unequivocally established, its impact on working memory needs to be studied. This study, funded by the Cognitive Science Research Initiative, Department of Science & Technology, Government of India, analyzed the effect of one-year chess training on the working memory of children. A pretest–posttest with control group design was used, with 52 children in the experimental group and 50 children in the control group. The sample was selected from children studying in school (grades 3 to 9), which included both the genders. The experimental group underwent weekly chess training for one year, while the control group was involved in extracurricular activities. Working memory was measured by two subtests of WISC-IV INDIA. The Digit Span Subtest involves recalling a list of numbers of increasing length presented orally in forward and in reverse order, and the Letter–Number Sequencing Subtest involves rearranging jumbled alphabets and numbers presented orally following a given rule. Both tasks require the child to receive and briefly store information, manipulate it, and present it in a changed format. The Children were trained using Winning Moves curriculum, audio- visual learning method, hands-on- chess training and recording the games using score sheets, analyze their mistakes, thereby increasing their Meta-Analytical abilities. They were also trained in Opening theory, Checkmating techniques, End-game theory and Tactical principles. Pre equivalence of means was established. Analysis revealed that the experimental group had significant gains in working memory compared to the control group. The present study clearly establishes a link between chess training and working memory. The transfer of chess training to the improvement of working memory could be attributed to the fact that while playing chess, children evaluate positions, visualize new positions in their mind, analyze the pros and cons of each move, and choose moves based on the information stored in their mind. If working-memory’s capacity could be expanded or made to function more efficiently, it could result in the improvement of executive functions as well as the scholastic performance of the child. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chess%20training" title="chess training">chess training</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20development" title=" cognitive development"> cognitive development</a>, <a href="https://publications.waset.org/abstracts/search?q=executive%20functions" title=" executive functions"> executive functions</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20children" title=" school children"> school children</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20memory" title=" working memory"> working memory</a> </p> <a href="https://publications.waset.org/abstracts/61490/improving-working-memory-in-school-children-through-chess-training" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61490.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">263</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">12302</span> Neural Network Based Approach of Software Maintenance Prediction for Laboratory Information System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vuk%20M.%20Popovic">Vuk M.

After that, any modification to it corresponds to maintenance. Software maintenance involves modifications to keep a software project usable in a changed or a changing environment, to correct discovered faults, and modifications, and to improve performance or maintainability. Software maintenance and management of software maintenance are recognized as two most important and most expensive processes in a life of a software product. This research is basing the prediction of maintenance, on risks and time evaluation, and using them as data sets for working with neural networks. The aim of this paper is to provide support to project maintenance managers. They will be able to pass the issues planned for the next software-service-patch to the experts, for risk and working time evaluation, and afterward to put all data to neural networks in order to get software maintenance prediction. This process will lead to the more accurate prediction of the working hours needed for the software-service-patch, which will eventually lead to better planning of budget for the software maintenance projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laboratory%20information%20system" title="laboratory information system">laboratory
