Due to the refractory characteristic and high chemical activity at elevated temperature, electrostatic levitation technique has been utilized to fulfill the rapid solidification of RHEA. Several RHEAs consisting W, Ta, Mo, Nb, Zr have been selected to perform the undercooling and rapid solidification by ESL. They are substantially undercooled by up to 0.2TL. The evolution of as-solidified microstructure and component redistribution with undercooling have been investigated by SEM, EBSD, and EPMA analysis. According to the EPMA results of composing elements at different undercooling levels, the chemical distribution relevant to undercooling was also analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20distribution" title="chemical distribution">chemical distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=high-entropy%20alloy" title=" high-entropy alloy"> high-entropy alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20solidification" title=" rapid solidification"> rapid solidification</a>, <a href="https://publications.waset.org/abstracts/search?q=undercooling" title=" undercooling"> undercooling</a> </p> <a href="https://publications.waset.org/abstracts/127404/undercooling-of-refractory-high-entropy-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127404.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">128</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">20</span> The Effects of Cultural Self-Efficacy and Perceived Social Support on Acculturative Stress of International Postgraduate Students in the United Kingdom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rhea%20Mathews">Rhea Mathews</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the study is to investigate the effects of perceived social support and cultural self-efficacy on the acculturative stress of international postgraduate students in the United Kingdom. The study adopted Berry, Kim, Minde & Mok’s (1987) acculturative framework on acculturative stress and examined the relationship between the variables. The study hypothesized that perceived social support and cultural self-efficacy would predict lower levels of acculturative stress among students. Postgraduate students in the United Kingdom (N = 76) completed three surveys measuring the variables; Acculturative Stress Scale for International Students, Multidimensional Scale of Perceived Social Support, and Cultural Self-efficacy for Adolescents. To evaluate the role of the perceived social support and cultural self-efficacy in determining the acculturative stress level of international students, multiple linear regression was employed. Both independent variables exhibited a significant, negative relationship with acculturative stress (p < 0.001; p < 0.01). Results described that cultural self-efficacy and perceived social support significantly predicted acculturative stress (p < 0.01). Together, the variables accounted for 22% of the variance in acculturative stress scores (adjusted R² = 0.22), with cultural self-efficacy playing a larger role in predicting the dependent variable. Limitations and implications of the study are noted. The findings of the study are discussed in relation to enhancing international students’ acculturative experience when relocating to a new environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acculturative%20stress" title="acculturative stress">acculturative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=coping" title=" coping"> coping</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20adjustment" title=" cultural adjustment"> cultural adjustment</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20self-efficacy" title=" cultural self-efficacy"> cultural self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20education" title=" international education"> international education</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20students" title=" international students"> international students</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20social%20support" title=" perceived social support "> perceived social support </a> </p> <a href="https://publications.waset.org/abstracts/92552/the-effects-of-cultural-self-efficacy-and-perceived-social-support-on-acculturative-stress-of-international-postgraduate-students-in-the-united-kingdom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92552.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">327</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">19</span> Enhanced High-Temperature Strength of HfNbTaTiZrV Refractory High-Entropy Alloy via Al₂O₃ Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bingjie%20Wang">Bingjie Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qianqian%20Qang"> Qianqian Qang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nan%20Lu"> Nan Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiubing%20Liang"> Xiubing Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Baolong%20Shen"> Baolong Shen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Novel composites of HfNbTaTiZrV refractory high-entropy alloy (RHEA) reinforced with 0-5 vol.% Al₂O₃ particles have been synthesized by vacuum arc melting. The microstructure evolution, compressive mechanical properties at room and elevated temperatures, as well as strengthening mechanism of the composites, are analyzed. The HfNbTaTiZrV RHEA reinforced with 4 vol.% Al₂O₃ displays excellent phase stability at elevated temperatures. A superior compressive yield strength of 2700 MPa at room temperature, 1392 MPa at 800 °C, and 693 MPa at 1000 °C has been obtained for this composite. The improved yield strength results from multiple strengthening mechanisms caused by Al₂O₃ addition, including interstitial strengthening, grain boundary strengthening, and dispersion strengthening. Besides, the effects of interstitial strengthening increase with the temperature and is the main strengthening mechanism at elevated temperatures. These findings not only promote the development of oxide-reinforced RHEAs for challenging engineering applications but also provide guidelines for the design of light refractory materials with multiple strengthening mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al%E2%82%82O%E2%82%83-reinforcement" title="Al₂O₃-reinforcement">Al₂O₃-reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=HfNbTaTiZrV" title=" HfNbTaTiZrV"> HfNbTaTiZrV</a>, <a href="https://publications.waset.org/abstracts/search?q=refractory%20high-entropy%20alloy" title=" refractory high-entropy alloy"> refractory high-entropy alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=interstitial%20strengthening" title=" interstitial strengthening"> interstitial strengthening</a> </p> <a href="https://publications.waset.org/abstracts/158860/enhanced-high-temperature-strength-of-hfnbtatizrv-refractory-high-entropy-alloy-via-al2o3-reinforcement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158860.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">115</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">18</span> The Effects of Above-Average Precipitation after Extended Drought on Phytoplankton in Southern California Surface Water Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margaret%20K.%20Spoo-Chupka">Margaret K. Spoo-Chupka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Metropolitan Water District of Southern California (MWDSC) manages surface water reservoirs that are a source of drinking water for more than 19 million people in Southern California. These reservoirs experience periodic planktonic cyanobacteria blooms that can impact water quality. MWDSC imports water from two sources – the Colorado River (CR) and the State Water Project (SWP). The SWP brings supplies from the Sacramento-San Joaquin Delta that are characterized as having higher nutrients than CR water. Above average precipitation in 2017 after five years of drought allowed the majority of the reservoirs to fill. Phytoplankton was analyzed during the drought and after the drought at three reservoirs: Diamond Valley Lake (DVL), which receives SWP water exclusively, Lake Skinner, which can receive a blend of SWP and CR water, and Lake Mathews, which generally receives only CR water. DVL experienced a significant increase in water elevation in 2017 due to large SWP inflows, and there were no significant changes to total phytoplankton biomass, Shannon-Wiener diversity of the phytoplankton, or cyanobacteria biomass in 2017 compared to previous drought years despite the higher nutrient loads. The biomass of cyanobacteria that could potentially impact DVL water quality (Microcystis spp., Aphanizomenon flos-aquae, Dolichospermum spp., and Limnoraphis birgei) did not differ significantly between the heavy precipitation year and drought years. Compared to the other reservoirs, DVL generally has the highest concentration of cyanobacteria due to the water supply having greater nutrients. Lake Mathews’ water levels were similar in drought and wet years due to a reliable supply of CR water and there were no significant changes in the total phytoplankton biomass, phytoplankton diversity, or cyanobacteria biomass in 2017 compared to previous drought years. The biomass of cyanobacteria that could potentially impact water quality at Lake Mathews (L. birgei and Microcystis spp.) did not differ significantly between 2017 and previous drought years. Lake Mathews generally had the lowest cyanobacteria biomass due to the water supply having lower nutrients. The CR supplied most of the water to Lake Skinner during drought years, while the SWP was the primary source during 2017. This change in water source resulted in a significant increase in phytoplankton biomass in 2017, no significant change in diversity, and a significant increase in cyanobacteria biomass. Cyanobacteria that could potentially impact water quality at Skinner included: Microcystis spp., Dolichospermum spp., and A.flos-aquae. There was no significant difference in Microcystis spp. biomass in 2017 compared to previous drought years, but biomass of Dolichospermum spp. and A.flos-aquae were significantly greater in 2017 compared to previous drought years. Dolichospermum sp. and A. flos-aquae are two cyanobacteria that are more sensitive to nutrients than Microcystis spp., which are more sensitive to temperature. Patterns in problem cyanobacteria abundance among Southern California reservoirs as a result of above-average precipitation after more than five years of drought were most closely related to nutrient loading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drought" title="drought">drought</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoirs" title=" reservoirs"> reservoirs</a>, <a href="https://publications.waset.org/abstracts/search?q=cyanobacteria" title=" cyanobacteria"> cyanobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20phytoplankton%20ecology" title=" and phytoplankton ecology"> and phytoplankton ecology</a> </p> <a href="https://publications.waset.org/abstracts/78359/the-effects-of-above-average-precipitation-after-extended-drought-on-phytoplankton-in-southern-california-surface-water-reservoirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78359.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">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Study of Corrosion in Structures due to Chloride Infiltration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sukrit%20Ghorai">Sukrit Ghorai</a>, <a href="https://publications.waset.org/abstracts/search?q=Akku%20Aby%20Mathews"> Akku Aby Mathews</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corrosion in reinforcing steel is the leading cause for deterioration in concrete structures.

However, it has some problems, such as brittleness after plasma exposure. High-entropy alloys (RHEAs) are a new opportunity for this deficiency. So, the neutron shielding behavior of WNbMoVTa and WNbMoVTaCr₀.₅Al compositions were examined against He⁺ irradiation in this study. The mechanical and irradiation properties of the WNbMoVTa base composition were investigated by adding the Al and Cr elements. The mechanical alloying (MA) for 6 hours was applied to obtain RHEA powders. According to the X-ray diffraction (XRD) method, the body-centered cubic (BCC) phase and NbTa phase with a small amount of WC impurity that comes from vials and balls were determined after 6 h MA. Also, RHEA powders were consolidated with the spark plasma sintering (SPS) method (1500 ºC, 30 MPa, and 10 min). After the SPS method, (Nb,Ta)C and W₂C₀.₈₅ phases were obtained with the decomposition of WC and stearic acid that is added during MA based on XRD results. Also, the BCC phase was obtained for both samples. While the Al₂O₃ phase with a small intensity was seen for the WNbMoVTaCr₀.₅Al sample, the Ta₂VO₆ phase was determined for the base sample. These phases were observed as three different regions according to scanning electron microscopy (SEM). All elements were distributed homogeneously on the white region by measuring an electron probe micro-analyzer (EPMA) coupled with a wavelength dispersive spectroscope (WDS). Also, the grey region of the WNbMoVTa sample was rich in Ta, V, and O elements. However, the amount of Al and O elements was higher for the grey region of the WNbMoVTaCr₀.₅Al sample. The high amount of Nb, Ta, and C elements were determined for both samples. Archimedes’ densities that were measured with alcohol media were closer to the theoretical densities of RHEAs. These values were important for the microhardness and irradiation resistance of compositions. While the Vickers microhardness value of the WNbMoVTa sample was measured as ~11 GPa, this value increased to nearly 13 GPa with the WNbMoVTaCr₀.₅Al sample. These values were compatible with the wear behavior. The wear volume loss was decreased to 0.16×10⁻⁴ from 1.25×10⁻⁴ mm³ by the addition of Al and Cr elements to the WNbMoVTa. The He⁺ irradiation was conducted on the samples to observe surface damage. After irradiation, the XRD patterns were shifted to the left because of defects and dislocations. He⁺ ions were infused under the surface, so they created the lattice expansion. The peak shifting of the WNbMoVTaCr₀.₅Al sample was less than the WNbMoVTa base sample, thanks to less impact. A small amount of fuzz was observed for the base sample. This structure was removed and transformed into a wavy structure with the addition of Cr and Al elements. Also, the deformation hardening was actualized after irradiation. A lower amount of hardening was obtained with the WNbMoVTaCr₀.₅Al sample based on the changing microhardness values. The surface deformation was decreased in the WNbMoVTaCr₀.₅Al sample. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=refractory%20high%20entropy%20alloy" title="refractory high entropy alloy">refractory high entropy alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=microhardness" title=" microhardness"> microhardness</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20resistance" title=" wear resistance"> wear resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=He%E2%81%BA%20irradiation" title=" He⁺ irradiation"> He⁺ irradiation</a> </p> <a href="https://publications.waset.org/abstracts/173985/investigation-studies-of-wnbmovta-and-wnbmovtacr05al-refractory-high-entropy-alloys-as-plasma-facing-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173985.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">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Health and Safety Practices of Midsayapenos in Relation to The Governance of the Local Government Unit of Midsayap in Responding to the COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jolai%20R.%20Garca">Jolai R.

Early screening of plants for pathogenic infections can serve as a boon in the Agricultural sector. The standard microbiology techniques has not kept pace with the rapid enumeration and automated methods for bacteria detection. Electrochemical Impedance Spectroscopy (EIS) serves as a label free bio sensing technique to monitor pathogens in real time. The changes in the electrical impedance of a growing bacterial culture can be monitored to detect activity of microorganisms. In this study, we demonstrate development of a gold interdigitated electrode (gold IDE) based impedance biosensor to detect bacterial cells in real on-field crop samples. To calibrate our impedance measurement system, nutrient broth suspended Escherichia coli cells were used. We extended this calibrated protocol to identify the agricultural pathogens in real potato tuber samples. Distinct difference was seen in the impedance recorded for the healthy and infected potato samples. Our results support the potential application of this Impedance based biosensor in Agricultural pathogen detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensor" title=" biosensor"> biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20impedance%20spectroscopy" title=" electrochemical impedance spectroscopy"> electrochemical impedance spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=microelectrode" title=" microelectrode"> microelectrode</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogen%20detection" title=" pathogen detection"> pathogen detection</a> </p> <a href="https://publications.waset.org/abstracts/129796/impedance-based-biosensor-for-agricultural-pathogen-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129796.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">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Clinical Efficacy of Indigenous Software for Automatic Detection of Stages of Retinopathy of Prematurity (ROP)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joshi%20Manisha">Joshi Manisha</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivaram"> Shivaram</a>, <a href="https://publications.waset.org/abstracts/search?q=Anand%20Vinekar"> Anand Vinekar</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanya%20Susan%20Mathews"> Tanya Susan Mathews</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeshaswini%20Nagaraj"> Yeshaswini Nagaraj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Retinopathy of prematurity (ROP) is abnormal blood vessel development in the retina of the eye in a premature infant. The principal object of the invention is to provide a technique for detecting demarcation line and ridge detection for a given ROP image that facilitates early detection of ROP in stage 1 and stage 2. The demarcation line is an indicator of Stage 1 of the ROP and the ridge is the hallmark of typically Stage 2 ROP. Thirty Retcam images of Asian Indian infants obtained during routine ROP screening have been used for the analysis. A graphical user interface has been developed to detect demarcation line/ridge and to extract ground truth. This novel algorithm uses multilevel vessel enhancement to enhance tubular structures in the digital ROP images. It has been observed that the orientation of the demarcation line/ridge is normal to the direction of the blood vessels, which is used for the identification of the ridge/ demarcation line. Quantitative analysis has been presented based on gold standard images marked by expert ophthalmologist. Image based analysis has been based on the length and the position of the detected ridge. In image based evaluation, average sensitivity and positive predictive value was found to be 92.30% and 85.71% respectively. In pixel based evaluation, average sensitivity, specificity, positive predictive value and negative predictive value achieved were 60.38%, 99.66%, 52.77% and 99.75% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ROP" title="ROP">ROP</a>, <a href="https://publications.waset.org/abstracts/search?q=ridge" title=" ridge"> ridge</a>, <a href="https://publications.waset.org/abstracts/search?q=multilevel%20vessel%20enhancement" title=" multilevel vessel enhancement"> multilevel vessel enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical" title=" biomedical"> biomedical</a> </p> <a href="https://publications.waset.org/abstracts/13078/clinical-efficacy-of-indigenous-software-for-automatic-detection-of-stages-of-retinopathy-of-prematurity-rop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13078.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">410</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> PathoPy2.0: Application of Fractal Geometry for Early Detection and Histopathological Analysis of Lung Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rhea%20Kapoor">Rhea Kapoor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fractal dimension provides a way to characterize non-geometric shapes like those found in nature. The purpose of this research is to estimate Minkowski fractal dimension of human lung images for early detection of lung cancer. Lung cancer is the leading cause of death among all types of cancer and an early histopathological analysis will help reduce deaths primarily due to late diagnosis. A Python application program, PathoPy2.0, was developed for analyzing medical images in pixelated format and estimating Minkowski fractal dimension using a new box-counting algorithm that allows windowing of images for more accurate calculation in the suspected areas of cancerous growth. Benchmark geometric fractals were used to validate the accuracy of the program and changes in fractal dimension of lung images to indicate the presence of issues in the lung. The accuracy of the program for the benchmark examples was between 93-99% of known values of the fractal dimensions. Fractal dimension values were then calculated for lung images, from National Cancer Institute, taken over time to correctly detect the presence of cancerous growth. For example, as the fractal dimension for a given lung increased from 1.19 to 1.27 due to cancerous growth, it represents a significant change in fractal dimension which lies between 1 and 2 for 2-D images. Based on the results obtained on many lung test cases, it was concluded that fractal dimension of human lungs can be used to diagnose lung cancer early. The ideas behind PathoPy2.0 can also be applied to study patterns in the electrical activity of the human brain and DNA matching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractals" title="fractals">fractals</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathological%20analysis" title=" histopathological analysis"> histopathological analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title=" lung cancer"> lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Minkowski%20dimension" title=" Minkowski dimension"> Minkowski dimension</a> </p> <a href="https://publications.waset.org/abstracts/96476/pathopy20-application-of-fractal-geometry-for-early-detection-and-histopathological-analysis-of-lung-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96476.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">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Determining the Prevalence and Risk Factors of Postpartum Depression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerald%20H.%20Artisen">Gerald H.

This research utilized a cross-sectional descriptive study to assess postpartum depression prevalence and identify contributing factors in Pasil, utilizing a quantitative approach and collecting data on sociodemographic characteristics, obstetric data, and the Edinburgh Postnatal Depression Scale. The study concluded that probable depression can be seen among mothers in the Pasil, which resulted in a risk of suicidality with a percentage of 40.08. Additionally, most of the respondents are aged 28–32, married, have a college degree, are unemployed, have a monthly income of 1,000–5,000, are female, have hypertension, gave birth naturally, have two children, have a planned pregnancy, and are currently breastfeeding. Lastly, the study found that mothers in Pasil who have unplanned pregnancies under obstetric factors are at high risk of developing postpartum depression, with a p-value below the 0.05 level. The study recommends barangay health professionals develop initiatives to inform aspiring mothers about postpartum depression (PPD) and resources to help them adjust to motherhood. It also recommends frequent check-ins with new mothers to identify special healthcare needs. Programs should be independently funded by LGUs, and support from family and relatives is recommended to prevent PPD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maternal%20health" title="maternal health">maternal health</a>, <a href="https://publications.waset.org/abstracts/search?q=postpartum%20depression" title=" postpartum depression"> postpartum depression</a>, <a href="https://publications.waset.org/abstracts/search?q=mothers" title=" mothers"> mothers</a>, <a href="https://publications.waset.org/abstracts/search?q=Pasil" title=" Pasil"> Pasil</a> </p> <a href="https://publications.waset.org/abstracts/191524/determining-the-prevalence-and-risk-factors-of-postpartum-depression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191524.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">29</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Conversion from Catholicism to Islam in and out of Prison: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nerissa%20Gloria%20Balboa">Nerissa Gloria Balboa</a>, <a href="https://publications.waset.org/abstracts/search?q=Aire%20Yukdawan"> Aire Yukdawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Venice%20Gordula"> Venice Gordula</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhea%20Jannagen%20Curva"> Rhea Jannagen Curva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research examined the lived experiences and compared their similarities and differences of former Catholics turned Muslim converts in and out of prison. Qualitative comparative study with an Interpretative Phenomenological Analysis approach was used to explore the lives of Muslim converts. Interviews were conducted at Islamic Studies, Call and Guidance of the Philippines (ISCAG) and Tarbiyyah Islamic Female Institute for Muslim converts out of prison, New Bilibid Prison (NBP) and Correctional Institution for Women (CIW) for Muslim converts in prison. Results of the study show that first, for Muslim converts out of prison, exploration begins through (1) experiences of Catholicism as a norm in the family and eventual realization of its emptiness in practice, (2) experiences of Islam as a norm in the environment and discovery of meaningfulness of Islam (3) experiences of gradual holistic transformation of being a Muslim; and (4) experiences of extension of oneself towards family and society. Secondly, for Muslim converts in prison, exploration begins through (1) experiences of Apathy towards Catholicism and eventual deviation from moral standards, (2) experiences of prison condition as an environment of reflection on spirituality; and (3) experiences of positive effects of being a Muslim inside Prison. Comparisons show that there exists similarities and differences across the two settings in terms of (1) experiences of Catholicism and the degree of its internalization and actualization, (2) experiences of Islamic encounters and the process of conversion; and (3) experience of Islamic devotion and Islamic construct for the self. Theoretical bases of religious conversion found in unique contexts are discussed, initiating a paradigm shift of thinking that is needed to address the deeply rooted prejudices within Catholic and Islamic circles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catholicism" title="Catholicism">Catholicism</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20conversion" title=" Islamic conversion"> Islamic conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20psychology" title=" social psychology"> social psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a> </p> <a href="https://publications.waset.org/abstracts/62343/conversion-from-catholicism-to-islam-in-and-out-of-prison-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62343.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">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Partial Triphallia: The First Case Report of External and Internal Penile Triplication in a Cadaver</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madeleine%20Gadd">Madeleine Gadd</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20How"> Rose How</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Mathews"> Edward Mathews</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Buchanan"> John Buchanan</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicky%20Cottrell"> Vicky Cottrell</a>, <a href="https://publications.waset.org/abstracts/search?q=Andre%20Coetzee"> Andre Coetzee</a>, <a href="https://publications.waset.org/abstracts/search?q=Karuna%20Katti"> Karuna Katti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Triphallia, a congenital anomaly describing the presence of three distinct penile shafts, has been reported only once in the literature. This case report describes the serendipitous discovery of the first reported human case of partial orthotopic triphallia during cadaveric dissection. Case Summary: Despite the normal appearance of external genitalia on examination, the dissection of a 78-year-old male revealed a remarkable anatomical variation: two small supernumerary penises situated in a transverse orientation postero inferiorly to the primary penis. The main and the larger supernumerary penile shafts displayed their own corpora cavernosa and glans penis, sharing a single urethra, which coursed through the secondary penis prior to its passage through the primary penis. The smallest of the supernumerary penises was similar in dimension to the secondary penis, at 3.7cm long and 1.2cm wide (compared to the secondary penis at 3.8cm long and 1.3cm wide). However, it lacked a urethra and a typical arrangement of the corpora cavernosa and spongiosum, making this a case of partial triphallia rather than true triphallia. Conclusion: This case report provides a comprehensive anatomical description of partial triphallia in a cadaver, shedding light on the morphology, embryology, and clinical implications of this anomaly. This case report underscores the importance of meticulous anatomical dissections, particularly since, without dissection, this anatomical variation would have remained undiscovered. Although we can only speculate the functional implications of this condition, understanding such anatomical variations contributes to both knowledge of human anatomy and clinical management, should the condition be encountered in living individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=triphallia" title="triphallia">triphallia</a>, <a href="https://publications.waset.org/abstracts/search?q=diphallia" title=" diphallia"> diphallia</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20abnormalities" title=" congenital abnormalities"> congenital abnormalities</a>, <a href="https://publications.waset.org/abstracts/search?q=genitourinary%20abnormalities" title=" genitourinary abnormalities"> genitourinary abnormalities</a>, <a href="https://publications.waset.org/abstracts/search?q=urology" title=" urology"> urology</a> </p> <a href="https://publications.waset.org/abstracts/169486/partial-triphallia-the-first-case-report-of-external-and-internal-penile-triplication-in-a-cadaver" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169486.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">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Factors Affecting Online Health Seeking Behaviors in Middle-Income Class Filipino Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reinzo%20Vittorio%20B.%20Cardenas">Reinzo Vittorio B.

The study aimed to explore and understand the factors affecting online health-seeking behaviors in middle-income class adults in Metro Manila. The study was conducted from March to April of 2021 with a sample size of 200 individuals aged 20 to 49 years old. The study was delivered via an online survey that used a questionnaire adapted from the research of Lee et al. (2015). Specifically, the survey consisted of three sections: assessing web-based health-seeking behaviors, consultation with health professionals, and participants' hesitancy to consult with physicians, which used a mix of a 5-point Likert-type scale with multiple responses and multiple-choice options. The results showed that the age and educational attainment of the respondents had a negative effect while presenting a positive effect of socio-economic status on health-seeking behavior. Lastly, there was a significant effect of participant’s hesitancy for professional consultation on their health-seeking behavior. The results gleaned from the study indicated that various individual and socio-economic factors might significantly affect one’s health-seeking behaviors. Although hesitancy had a significant effect on the spectrum of health-seeking behaviors, this does not imply that certain factors are specifically related to an individual’s tendency to seek health information. This information instead becomes essential in understanding the patient-physician relationship and giving patients a more holistic treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health-seeking%20behavior" title="health-seeking behavior">health-seeking behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20information" title=" health information"> health information</a>, <a href="https://publications.waset.org/abstracts/search?q=Internet" title=" Internet"> Internet</a>, <a href="https://publications.waset.org/abstracts/search?q=physician%20consultation" title=" physician consultation"> physician consultation</a> </p> <a href="https://publications.waset.org/abstracts/138833/factors-affecting-online-health-seeking-behaviors-in-middle-income-class-filipino-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138833.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">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Investigating the Flavin-Dependent Thymidylate Synthase (FDTS) Enzyme from Clostridioides Difficile (C. diff)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidra%20Shaw">Sidra Shaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarenna%20Shaw"> Sarenna Shaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Chae%20Joon%20Lee"> Chae Joon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Irimpan%20Mathews"> Irimpan Mathews</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Koehn"> Eric Koehn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the biggest public health concerns of our time is increasing antimicrobial resistance. As of 2019, the CDC has documented more than 2.8 million serious antibiotic resistant infections in the United States. Currently, antibiotic resistant infections are directly implicated in over 750,000 deaths per year globally. On our current trajectory, British economist Jim O’Neill predicts that by 2050, an additional 10 million people (about half the population of New York) will die annually due to drug resistant infections. As a result, new biochemical pathways must be targeted to generate next generation antibiotic drugs that will be effective against drug resistant bacteria. One enticing target is the biosynthesis of DNA within bacteria, as few drugs interrupt this essential life process. Thymidylate synthase enzymes are essential for life as they catalyze the synthesis of a DNA building block, 2′-deoxythymidine-5′-monophosphate (dTMP). In humans, the thymidylate synthase enzyme (TSase) has been shown to be distinct from the flavin-dependent thymidylate synthase (FDTS) produced by many pathogenic bacteria. TSase and FDTS have distinct structures and mechanisms of catalysis, which should allow selective inhibition of FDTS over human TSase. Currently, C. diff is one of the most antibiotic resistant bacteria, and no drugs that target thymine biosynthesis exist for C. diff. Here we present the initial biochemical characterization of FDTS from C. diff. Specifically, we examine enzyme kinetics and binding features of this enzyme to determine the nature of interaction with ligands/inhibitors and understand the molecular mechanism of catalysis. This research will provide more insight into the targetability of the C. diff FDTS enzyme for novel antibiotic drugs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flavin-dependent%20thymidylate%20synthase" title="flavin-dependent thymidylate synthase">flavin-dependent thymidylate synthase</a>, <a href="https://publications.waset.org/abstracts/search?q=FDTS" title=" FDTS"> FDTS</a>, <a href="https://publications.waset.org/abstracts/search?q=clostridioides%20difficile" title=" clostridioides difficile"> clostridioides difficile</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20diff" title=" C. diff"> C. diff</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance" title=" antibiotic resistance"> antibiotic resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20synthesis" title=" DNA synthesis"> DNA synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20kinetics" title=" enzyme kinetics"> enzyme kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=binding%20features" title=" binding features"> binding features</a> </p> <a href="https://publications.waset.org/abstracts/165607/investigating-the-flavin-dependent-thymidylate-synthase-fdts-enzyme-from-clostridioides-difficile-c-diff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165607.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">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Correlates of Modes of Transportation to Work among Working Adults in Ernakulam District, Kerala</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjaly%20Joseph">Anjaly Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=Elezebeth%20Mathews"> Elezebeth Mathews</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transportation and urban planning is the least recognised area for physical activity promotion in India, unlike developed regions. Identifying the preferred transportation modalities and factors associated with it is essential to address these lacunae. The objective of the study was to assess the prevalence of modes of transportation to work, and its correlates among working adults in Ernakulam District, Kerala. A cross sectional study was conducted among 350 working individuals in the age group of 18-60 years, selected through multi-staged stratified random sampling in Ernakulam district of Kerala. The inclusion criteria were working individuals 18-60 years, workplace at a distance of more than 1 km from the home and who worked five or more days a week. Pregnant women/women on maternity leave and drivers (taxi drivers, autorickshaw drivers, and lorry drivers) were excluded. An interview schedule was used to capture the modes of transportation namely, public, private and active transportation, socio demographic details, travel behaviour, anthropometric measurements and health status. Nearly two-thirds (64 percent) of them used private transportation to work, while active commuters were only 6.6 percent. The correlates identified for active commuting compared to other modes were low socio-economic status (OR=0.22, CI=0.5-0.85) and presence of a driving license (OR=4.95, CI= 1.59-15.45). The correlates identified for public transportation compared to private transportation were female gender (OR= 17.79, CI= 6.26-50.31), low income (OR=0.33, CI= 0.11-0.93), being unmarried (OR=5.19, CI=1.46-8.37), presence of no or only one private vehicle in the house (OR=4.23, CI=1.24-20.54) and presence of convenient public transportation facility to workplace (OR=3.97, CI= 1.66-9.47). The association between body mass index (BMI) and public transportation were explored and found that public transport users had lesser BMI than private commuters (OR=2.30, CI=1.23-4.29). Policies that encourage active and public transportation needs to be introduced such as discouraging private vehicle through taxes, introduction of convenient and safe public transportation facility, walking/cycling paths, and paid parking facility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20transportation" title="active transportation">active transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=correlates" title=" correlates"> correlates</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transportation" title=" public transportation"> public transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20modes" title=" transportation modes"> transportation modes</a> </p> <a href="https://publications.waset.org/abstracts/92151/correlates-of-modes-of-transportation-to-work-among-working-adults-in-ernakulam-district-kerala" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92151.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">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Variation in N₂ Fixation and N Contribution by 30 Groundnut (Arachis hypogaea L.)

Dakora</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Africa, poor nutrient availability, particularly N and P, coupled with low soil moisture due to erratic rainfall, constitutes the major crop production constraints. Although inorganic fertilizers are an option for meeting crop nutrient requirements for increased grain yield, the high cost and scarcity of inorganic inputs make them inaccessible to resource-poor farmers in Africa. Because crops grown on such nutrient-poor soils are micronutrient deficient, incorporating N₂-fixing legumes into cropping systems can sustainably improve crop yield and nutrient accumulation in the grain. In Africa, groundnut can easily form an effective symbiosis with native soil rhizobia, leading to marked N contribution in cropping systems. In this study, field experiments were conducted at Blesbokfontein in Mpumalanga Province to assess N₂ fixation and N contribution by 30 groundnut varieties during the 2018/2019 planting season using the ¹⁵N natural abundance technique. The results revealed marked differences in shoot dry matter yield, symbiotic N contribution, soil N uptake and grain yield among the groundnut varieties. The percent N derived from fixation ranged from 37 to 44% for varieties ICGV131051 and ICGV13984. The amount of N-fixed ranged from 21 to 58 kg/ha for varieties Chinese and IS-07273, soil N uptake from 31 to 80 kg/ha for varieties IS-07947 and IS-07273, and grain yield from 193 to 393 kg/ha for varieties ICGV15033 and ICGV131096, respectively. Compared to earlier studies on groundnut in South Africa, this study has shown low N₂ fixation and N contribution to the cropping systems, possibly due to environmental factors such as low soil moisture. Because the groundnut varieties differed in their growth, symbiotic performance and grain yield, more field testing is required over a range of differing agro-ecologies to identify genotypes suitable for different cropping environments <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C2%B9%E2%81%B5N%20natural%20abundance" title="¹⁵N natural abundance">¹⁵N natural abundance</a>, <a href="https://publications.waset.org/abstracts/search?q=percent%20N%20derived%20from%20fixation" title=" percent N derived from fixation"> percent N derived from fixation</a>, <a href="https://publications.waset.org/abstracts/search?q=amount%20of%20N-fixed" title=" amount of N-fixed"> amount of N-fixed</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20yield" title=" grain yield"> grain yield</a> </p> <a href="https://publications.waset.org/abstracts/140599/variation-in-n2-fixation-and-n-contribution-by-30-groundnut-arachis-hypogaea-l-varieties-grown-in-blesbokfontein-mpumalanga-province-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140599.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">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> The Implementation of Sexual and Reproductive Health Education Policy in Schools in Asia and Africa: A Scoping Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rhea%20Khosla">Rhea Khosla</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Tzortziou-Brown"> Victoria Tzortziou-Brown</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Adolescent SRH has been neglected since the start of the millennium. Adolescents comprise 16% of the global population, with the largest proportion living in Asia (650 million). By late adolescence, individuals in these regions are likely to become sexually active, and thus they must understand their SRH rights. Many lack knowledge of SRH, using unreliable sources for such information. Sex education is necessary to standardize and inform sexual knowledge, which empowers adolescents to make informed SRH decisions. School is an appropriate environment for this, however, SRH education requires effective policy to enforce. Nonetheless, this issue remains of low political priority in Asia and Africa. Current literature on sex education policy in schools in these regions is scarce and tends to have broad aims. Thus, a scoping review was necessary. Methods: Literature searches were conducted in February 2023 using six databases, including grey literature databases (PubMed, Scopus, Embase, Web of Science, Google Scholar, Global Index Medicus), returning a total of 1537 unique articles. After screening titles, abstracts and full text, 17 articles remained. References of included articles were additionally searched, producing a further 7 articles, which then underwent thematic analysis Results: Most countries in Africa and Asia did not have studies on this topic. Studies derived data from interviews with key stakeholders and quantitative methods quantified questionnaire responses. Barriers were: policy/curriculum issues, societal opinions, teaching discomfort, and lack of educator training. Limitations were insufficient timing, inconsistent implementation, insufficient hours dedicated to teaching, education received late into schooling, and discrepancies between teachers, schools, and students about whether policies were being implemented. Discussion: Based on the existing limited evidence, a cultural shift to reduce stigma seems necessary, alongside teacher and student involvement in policy formulation with effective implementation monitoring and educator training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescent" title="adolescent">adolescent</a>, <a href="https://publications.waset.org/abstracts/search?q=Africa" title=" Africa"> Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=Asia" title=" Asia"> Asia</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20and%20reproductive%20health" title=" sexual and reproductive health"> sexual and reproductive health</a>, <a href="https://publications.waset.org/abstracts/search?q=policy" title=" policy"> policy</a> </p> <a href="https://publications.waset.org/abstracts/183082/the-implementation-of-sexual-and-reproductive-health-education-policy-in-schools-in-asia-and-africa-a-scoping-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183082.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">45</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Exploring the Relationship Between Past and Present Reviews: The Influence of User Generated Content on Future Hotel Guest Experience Perceptions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sacha%20Joseph-Mathews">Sacha Joseph-Mathews</a>, <a href="https://publications.waset.org/abstracts/search?q=Leili%20Javadpour"> Leili Javadpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the tourism industry, hoteliers spend millions annually on marketing and positioning efforts for their respective hotels, all in an effort to create a specific image in the minds of the consumer. Yet despite extensive efforts to seduce potential hotel guests with sophisticated advertising messages generated by hotel entities, consumers continue to mistrust corporate branding, preferring instead to place their trust in the reviews of their consumer peers. In today’s complex and cluttered marketplace, online reviews can serve as a mediator for consumers who do not have actual knowledge and experiences with the brand, but are in the process of deciding whether or not to engage in a consumption exercise. Traditionally, consumers have used online reviews as a source of comfort and confirmation of a product/service’s positioning. But today, very few customers make any purchase decisions without first researching existing user reviews, making reviews more of a necessity, rather than a luxury in the purchase decision process. The influence of user generated content (UGC) is amplified in the tourism industry; as more than a third of potential hotel guests will not book a room without first reading a review. As corporate branding becomes less relevant and online reviews become more important, how much of the consumer’s stay expectations are being dictated by existing UGC? Moreover, as hotel guest experience a hotel through the lens of an existing review, how much of their stay and in turn their review, would have been influenced by those reviews that they read? Ultimately, there is the potential for UGC to dictate what potential guests will be most critical about, and or most focused on during their stay. If UGC is a stronger influencer in the purchase decision process than corporate branding, doesn’t it have the potential to dictate, the entire stay experience by influencing the expectations of the guest prior to them arriving on the property? For example, if a hotel is an eco-destination and they focus their branding on their website around sustainability and the retreat nature of the hotel. Yet, guest reviews constantly discuss how dissatisfactory the service and food was with no mention of nature or sustainability, will future reviews then focus primarily on the food? Using text analysis software to examine over 25,000 online reviews, we explore the extent to which new reviews are influenced by wording used in previous reviews for a hotel property, versus content generated by corporate positioning. Additionally, we investigate how distinct hotel related UGC is across different types of tourism destinations. Our findings suggest that UGC can have a greater impact on future reviews, than corporate branding and there is more cohesiveness across UGC of different types of hotel properties than anticipated. A model of User Generated Content Influence is presented and the managerial impact of the power of online reviews to trump corporate branding and shape future user experiences is discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=user%20generated%20content" title="user generated content">user generated content</a>, <a href="https://publications.waset.org/abstracts/search?q=UGC" title=" UGC"> UGC</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20branding" title=" corporate branding"> corporate branding</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20reviews" title=" online reviews"> online reviews</a>, <a href="https://publications.waset.org/abstracts/search?q=hotels%20and%20tourism" title=" hotels and tourism"> hotels and tourism</a> </p> <a href="https://publications.waset.org/abstracts/167186/exploring-the-relationship-between-past-and-present-reviews-the-influence-of-user-generated-content-on-future-hotel-guest-experience-perceptions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167186.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">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Speech and Swallowing Function after Tonsillo-Lingual Sulcus Resection with PMMC Flap Reconstruction: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Rhea%20Devaiah">K.

Premalatha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Tonsillar Lingual sulcus is the area between the tonsils and the base of the tongue. The surgical resection of the lesions in the head and neck results in changes in speech and swallowing functions. The severity of the speech and swallowing problem depends upon the site and extent of the lesion, types and extent of surgery and also the flexibility of the remaining structures. Need of the study: This paper focuses on the importance of speech and swallowing rehabilitation in an individual with the lesion in the Tonsillar Lingual Sulcus and post-operative functions. Aim: Evaluating the speech and swallow functions post-intensive speech and swallowing rehabilitation. The objectives are to evaluate the speech intelligibility and swallowing functions after intensive therapy and assess the quality of life. Method: The present study describes a report of an individual aged 47years male, with the diagnosis of basaloid squamous cell carcinoma, left tonsillar lingual sulcus (pT2n2M0) and underwent wide local excision with left radical neck dissection with PMMC flap reconstruction. Post-surgery the patient came with a complaint of reduced speech intelligibility, and difficulty in opening the mouth and swallowing. Detailed evaluation of the speech and swallowing functions were carried out such as OPME, articulation test, speech intelligibility, different phases of swallowing and trismus evaluation. Self-reported questionnaires such as SHI-E(Speech handicap Index- Indian English), DHI (Dysphagia handicap Index) and SESEQ -K (Self Evaluation of Swallowing Efficiency in Kannada) were also administered to know what the patient feels about his problem. Based on the evaluation, the patient was diagnosed with pharyngeal phase dysphagia associated with trismus and reduced speech intelligibility. Intensive speech and swallowing therapy was advised weekly twice for the duration of 1 hour. Results: Totally the patient attended 10 intensive speech and swallowing therapy sessions. Results indicated misarticulation of speech sounds such as lingua-palatal sounds. Mouth opening was restricted to one finger width with difficulty chewing, masticating, and swallowing the bolus. Intervention strategies included Oro motor exercise, Indirect swallowing therapy, usage of a trismus device to facilitate mouth opening, and change in the food consistency to help to swallow. A practice session was held with articulation drills to improve the production of speech sounds and also improve speech intelligibility. Significant changes in articulatory production and speech intelligibility and swallowing abilities were observed. The self-rated quality of life measures such as DHI, SHI and SESE Q-K revealed no speech handicap and near-normal swallowing ability indicating the improved QOL after the intensive speech and swallowing therapy. Conclusion: Speech and swallowing therapy post carcinoma in the tonsillar lingual sulcus is crucial as the tongue plays an important role in both speech and swallowing. The role of Speech-language and swallowing therapists in oral cancer should be highlighted in treating these patients and improving the overall quality of life. With intensive speech-language and swallowing therapy post-surgery for oral cancer, there can be a significant change in the speech outcome and swallowing functions depending on the site and extent of lesions which will thereby improve the individual’s QOL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20cancer" title="oral
