The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals. Objective: To determine the prevalence and characteristics of consumption of nutraceuticals in undergraduate students. Methodology: Cross-sectional study. It was a simple random sampling with the Statcalc EpiInfo software vr 6.04. It was designed an instrument for collection of demographic data and consumption of nutraceuticals. Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.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">576</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">113</span> Modeling and Simulation of a Cycloconverter with a Bond Graph Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Ayala-Jaimes">Gerardo Ayala-Jaimes</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilberto%20Gonzalez-Avalos"> Gilberto Gonzalez-Avalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Allen%20A.%20Castillo"> Allen A.

Cycloconverters, used in motor control, demonstrate the viability of graphical modeling. The use of Bonds is proposed to model the hybrid interaction of the system, and the results are displayed through simulations using 20Sim and Multisim software. The motivation behind developing these models with a graphical approach is to design and build low-cost energy converters, thereby making the main contribution of this document the modeling and simulation of a single-phase cycloconverter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20graph" title="bond graph">bond graph</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20system" title=" hybrid system"> hybrid system</a>, <a href="https://publications.waset.org/abstracts/search?q=rectifier" title=" rectifier"> rectifier</a>, <a href="https://publications.waset.org/abstracts/search?q=cycloconverter" title=" cycloconverter"> cycloconverter</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a> </p> <a href="https://publications.waset.org/abstracts/187321/modeling-and-simulation-of-a-cycloconverter-with-a-bond-graph-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187321.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">37</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">112</span> An Owen Value for Cooperative Games with Pairwise a Priori Incompatibilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20M.%20Gallardo">Jose M.

In these games, the negotiation has two stages. In the first stage, players can only negotiate with others with whom they are compatible. In the second stage, the grand coalition will be formed. We introduce a value for these games. Given a game with a priori incompatibility (N,v,g), we consider the family of coalitions without incompatibility relations among their players. This family is a normal set system or coalition configuration Ig. Therefore, we can assign to each game with a priori incompatibilities (N,v,g) a game with coalition configuration (N,v, Ig). Now, in order to obtain a payoff vector for (N,v,g), it suffices to calculate a payoff vector for (N,v, Ig). To this end, we apply a value for games with coalition configuration. In our case, we will use the dual configuration value, which has been studied in the literature. With this method, we obtain a value for games with a priori incompatibilities, which is called the Owen value for a priori incompatibilities. We provide a characterization of this value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooperative%20game" title="cooperative game">cooperative game</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20with%20coalition%20configuration" title=" game with coalition configuration"> game with coalition configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=graph" title=" graph"> graph</a>, <a href="https://publications.waset.org/abstracts/search?q=independent%20set" title=" independent set"> independent set</a>, <a href="https://publications.waset.org/abstracts/search?q=Owen%20value" title=" Owen value"> Owen value</a>, <a href="https://publications.waset.org/abstracts/search?q=Shapley%20value" title=" Shapley value"> Shapley value</a> </p> <a href="https://publications.waset.org/abstracts/112957/an-owen-value-for-cooperative-games-with-pairwise-a-priori-incompatibilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112957.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">111</span> Gender Differences in the Impact and Subjective Interpretation of Childhood Sexual Abuse Survivors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Borja-Alvarez">T.

This has resulted in less research looking at the particular context in which this abuse takes place for boys and the impact this abuse may have on male survivors. The aim of this study is to examine the sex and age of the perpetrators of child sexual abuse and explore gender differences in the impact along with the subjective interpretation that survivors attribute to these experiences. The data for this study was obtained from Ecuadorian university students (M = 230, F = 293) who reported sexual abuse using the ISPCAN Child Abuse Screening Tool Retrospective version (ICAST-R). Participants completed Horowitz's Impact of Event Scale (IES) and were also requested to choose among neutral, positive, and negative adjectives to describe these experiences. The results indicate that in the case of males, perpetrators were both males (adults =27%, peers =20%, relatives =10.3%, cousins =7.4%) and young females (girlfriends or ex-girlfriends =25.6%, neighborhood =20.7%, school =16.7%, cousins =15.3%, strangers =12.8%). In contrast, almost all females reported that adult males were the perpetrators (relatives =29.6%, neighborhood =11.9%, strangers =19.9%, family friends =9.7%). Regarding the impact of these events, significant gender differences emerged. More females (50%) than males (20%) presented symptoms of post-traumatic stress disorder (PTSD). Gender differences also surfaced in the way survivors interpret their experiences. Almost half of the male participants selected the word “consensual” followed by the words “normal”, “helped me to mature”, “shameful”, “confusing”, and “traumatic”. In contrast, almost all females chose the word “non-consensual” followed by the words “shameful”, “traumatic”, “scary”, and “confusing”. In conclusion, the findings of this study suggest that young females and adult males were the most common perpetrators of sexually abused boys whereas adult males were the most common perpetrators of sexually abused girls. The impact and the subjective interpretation of these experiences were more negative for girls than for boys. The factors that account for the gender differences in the impact and the interpretation of these experiences need further exploration. It is likely that the cultural expectations of sexual behaviors for boys and girls in Latin American societies may partially explain the differential impact in the way these childhood sexual abuse experiences are interpreted in adulthood. In Ecuador, as is the case in other Latin American countries, the machismo culture not only accepts but encourages early sexual behaviors in boys and negatively judges premature sexual behavior in females. The result of these different sexual expectations may be that sexually abused boys may re-define these experiences as “consensual” and “normal” in adulthood, even though these were not consensual at the time of occurrence. Future studies are needed to more deeply understand the different contexts of sexual abuse for boys and girls in order to analyze the long-term impact of these experiences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abuse" title="abuse">abuse</a>, <a href="https://publications.waset.org/abstracts/search?q=child" title=" child"> child</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20differences" title=" gender differences"> gender differences</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual" title=" sexual"> sexual</a> </p> <a href="https://publications.waset.org/abstracts/145551/gender-differences-in-the-impact-and-subjective-interpretation-of-childhood-sexual-abuse-survivors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145551.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">103</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">110</span> Human Trafficking and Prostitution in Amsterdam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Roiz">Isabel Roiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Cossio"> Alejandra Cossio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This essay will talk about the problems of forced prostitution, human trafficking, and sexual exploitation in the Netherlands.

The evidence confirms the presence of an overall increase in asymmetric market volatility in the Peruvian share market since the 2007 crisis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20crisis" title="financial crisis">financial crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=Latin%20American%20Integrated%20Market" title=" Latin American Integrated Market"> Latin American Integrated Market</a>, <a href="https://publications.waset.org/abstracts/search?q=TARCH" title=" TARCH"> TARCH</a>, <a href="https://publications.waset.org/abstracts/search?q=GARCH" title=" GARCH"> GARCH</a> </p> <a href="https://publications.waset.org/abstracts/57884/the-impact-of-the-global-financial-crises-on-mila-stock-markets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57884.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">279</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">107</span> Phage Capsid for Efficient Delivery of Cytotoxic Drugs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simona%20Dostalova">Simona Dostalova</a>, <a href="https://publications.waset.org/abstracts/search?q=Dita%20Munzova"> Dita Munzova</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Maria%20Jimenez%20Jimenez"> Ana Maria Jimenez Jimenez</a>, <a href="https://publications.waset.org/abstracts/search?q=Marketa%20Vaculovicova"> Marketa Vaculovicova</a>, <a href="https://publications.waset.org/abstracts/search?q=Vojtech%20Adam"> Vojtech Adam</a>, <a href="https://publications.waset.org/abstracts/search?q=Rene%20Kizek"> Rene Kizek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The boom of nanomedicine in recent years has led to the development of numerous new nanomaterials that can be used as nanocarriers in the drug delivery. These nanocarriers can either be synthetic or natural-based. The disadvantage of many synthetic nanocarriers is their toxicity in patient’s body. Protein cages that can naturally be found in human body do not exhibit such disadvantage. However, the release of cargo from some protein cages in target cells can be problematic. As a special type of protein cages can serve the capsid of many viruses, including phage. Phages infect bacterial cells; therefore they are not harmful to human cells. The targeting of phage particles to cancer cells can be solved by producing of empty phage capsids during which the targeting moieties (e.g. peptides) can be cloned into genes of phage capsid to decorate its surface. Moreover, the produced capsids do not contain viral nucleic acid and are therefore not infectious to beneficial bacteria in the patient’s body. The protein cage composed of viral capsid is larger than other frequently used apoferritin cage but its size is still small enough to benefit from passive targeting by Enhanced Permeability and Retention effect. In this work, bacteriophage λ was used, both whole and its empty capsid for delivery of different cytotoxic drugs (cisplatin, carboplatin, oxaliplatin, etoposide and doxorubicin). Large quantities of phage λ were obtained from phage λ-producing strain of E. coli cultivated in medium with 0.2 % maltose. After killing of E. coli with chloroform and its removal by centrifugation, the phage was concentrated by ultracentrifugation at 130 000 g and 4 °C for 3 h. The encapsulation of the drugs was performed by infusion method and four different concentrations of the drugs were encapsulated (200; 100; 50; 25 µg/ml). Free molecules of drugs were removed by dialysis. The encapsulation was verified using spectrophotometric and electrochemical methods. The amount of encapsulated drug linearly increased with the amount of applied drug (determination coefficient R2=0.8013). 76% of applied drug was encapsulated in phage λ particles (concentration of 10 µg/ml), even with the highest applied concentration of drugs, 200 µg/ml. Only 1% of encapsulated drug was detected in phage DNA. Similar results were obtained with encapsulation in phage empty capsid. Therefore, it can be concluded that the encapsulation of drugs into phage particles is efficient and mostly occurs by interaction of drugs with protein capsid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytostatics" title="cytostatics">cytostatics</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocarriers" title=" nanocarriers"> nanocarriers</a>, <a href="https://publications.waset.org/abstracts/search?q=phage%20capsid" title=" phage capsid"> phage capsid</a> </p> <a href="https://publications.waset.org/abstracts/24931/phage-capsid-for-efficient-delivery-of-cytotoxic-drugs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24931.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">493</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">106</span> Health Status Monitoring of COVID-19 Patient's through Blood Tests and Naïve-Bayes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Arias-Alcaide">Carlos Arias-Alcaide</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Soguero-Ruiz"> Cristina Soguero-Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Paloma%20Santos-%C3%81lvarez"> Paloma Santos-Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Adri%C3%A1n%20Garc%C3%ADa-Romero"> Adrián García-Romero</a>, <a href="https://publications.waset.org/abstracts/search?q=Inmaculada%20Mora-Jim%C3%A9nez"> Inmaculada Mora-Jiménez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysing clinical data with computers in such a way that have an impact on the practitioners’ workflow is a challenge nowadays.

New wireless communication standards are developed every decade, and the year 2030 is expected to see the introduction of 6G. The primary objectives of 6G network and terminal designs are focused on sustainability and environmental friendliness. The International Telecommunication Union-Recommendation division (ITU-R) has established the minimum requirements for 6G, with peak and user data rates of 1 Tbps and 10-100 Gbps, respectively. In this context, Light Fidelity (Li-Fi) technology is the most promising candidate to meet these requirements. This article will explore the various advantages, features, and potential applications of Li-Fi technology, and compare it with 5G networking, to showcase its potential impact among other emerging technologies that aim to enable 6G networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=6G%20networks" title="6G networks">6G networks</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence%20%28AI%29" title=" artificial intelligence (AI)"> artificial intelligence (AI)</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-Fi%20technology" title=" Li-Fi technology"> Li-Fi technology</a>, <a href="https://publications.waset.org/abstracts/search?q=Terahertz%20%28THz%29%20communication" title=" Terahertz (THz) communication"> Terahertz (THz) communication</a>, <a href="https://publications.waset.org/abstracts/search?q=visible%20light%20communication%20%28VLC%29" title=" visible light communication (VLC)"> visible light communication (VLC)</a> </p> <a href="https://publications.waset.org/abstracts/167153/emerging-technology-for-6g-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167153.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">101</span> Telemedicine for Substance-Related Disorders: A Patient Satisfaction Survey among Individuals in Argentina</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badino%20Manuel">Badino Manuel</a>, <a href="https://publications.waset.org/abstracts/search?q=Farias%20Maria%20Alejandra"> Farias Maria Alejandra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Telemedicine (TM) has the potential to develop efficient and cost-effective means for delivering quality health care services and outcomes, showing equal or, in some cases, better results than in-person treatment. To analyze patient satisfaction with the use of TM becomes relevant because this can affect the results of treatment and the adherence to it. The aim is to assess patient satisfaction with telemedicine for treating substance-related disorders in a mental health service in Córdoba, Argentina. A descriptive cross-sectional study was conducted among patients with substance-related disorders (N=115). A patient satisfaction survey was conducted from December 2021 to March 2022. For a total of 115 participants, 59,1% were male, 38,3% were female and 2,6% non-binary. In relation to educational status, 40% finished university, 39,1% high school, and 20,9 % only primary school. Regarding age, 4,3 % were young, 92,2% were adults, and 3,5% were elderly. Regarding TM treatment, 95,7% reported being satisfied. Furthermore, 85,2% of users declared that they would continueTM treatment, and 14,8% said that they would not resume TM treatment. To conclude, high levels of patient satisfaction contributes to the continuity of TM modality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=telemedicine" title="telemedicine">telemedicine</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=substance-related%20disorders" title=" substance-related disorders"> substance-related disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20satisfaction" title=" patient satisfaction"> patient satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/152651/telemedicine-for-substance-related-disorders-a-patient-satisfaction-survey-among-individuals-in-argentina" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152651.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">108</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">100</span> Application of Digital Tools for Improving Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20L.%20Jim%C3%A9nez">José L.

In this paper a case study presents how were used some of these technologies by accompanying a classroom course, this in order to provide students with a different and innovative experience as their teacher usually presented the activities to develop. As students worked in the various activities, they increased their digital skills by employing unknown tools that helped them in their professional training. The twenty-first century teacher should consider the use of Information and Communication Technologies in the classroom thinking in skills that students of the digital age should possess. It also takes a brief look at the history of distance education and it is also highlighted the importance of integrating technology as part of the student's training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20tools" title="digital tools">digital tools</a>, <a href="https://publications.waset.org/abstracts/search?q=on-line%20learning" title=" on-line learning"> on-line learning</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networks" title=" social networks"> social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/17565/application-of-digital-tools-for-improving-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17565.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">403</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">99</span> Social Representations: Unplanned and Unwanted Pregnancy in Adolescents from Leon-Mexico </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Sierra">Alejandra Sierra</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20de%20los%20Angeles%20Covarrubias"> Maria de los Angeles Covarrubias</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillermo%20Julian%20Gonzalez"> Guillermo Julian Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Noe%20Alfaro"> Noe Alfaro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to identify the cultural dimensions of the terms unplanned pregnancy and unwanted pregnancy built by adolescent women, through the focus of the social representations. Two associative methods were used: free listings and the paired comparison. 72 female students between the ages of 15 and 19 were interviewed, from the downtown area of Leon Guanajuato, Mexico. Words related to inducer terms were classified into five thematic categories: facilitators, consequences, reactions, expectations, and lexicon. The results showed that the social representations of unplanned pregnancy highlighted elements related to economic difficulties and negative emotional aspects, while unwanted pregnancy was associated with negative emotional aspects such as anger, anxiety, and sadness. The meanings each person attributes to terms related to pregnancy are culturally constructed and differ between populations; therefore, more attention should be paid to understanding the cultural meanings and attitudes of people in fertility decision-making, including also the views of adolescent men and other types of population, stratified by age groups and social conditions. <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=qualitative%20research" title=" qualitative research"> qualitative research</a>, <a href="https://publications.waset.org/abstracts/search?q=unplanned%20pregnancy" title=" unplanned pregnancy"> unplanned pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=unwanted%20pregnancy" title=" unwanted pregnancy"> unwanted pregnancy</a> </p> <a href="https://publications.waset.org/abstracts/82829/social-representations-unplanned-and-unwanted-pregnancy-in-adolescents-from-leon-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82829.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">213</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">98</span> Negative RT-PCR in a Newborn Infected with Zika Virus: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vallejo%20Michael">Vallejo Michael</a>, <a href="https://publications.waset.org/abstracts/search?q=Acu%C3%B1a%20Edgar"> Acuña Edgar</a>, <a href="https://publications.waset.org/abstracts/search?q=Roa%20Juan%20David"> Roa Juan David</a>, <a href="https://publications.waset.org/abstracts/search?q=Pe%C3%B1uela%20Rosa"> Peñuela Rosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Parra%20Alejandra"> Parra Alejandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Casallas%20Daniela"> Casallas Daniela</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodriguez%20Sheyla"> Rodriguez Sheyla </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Congenital Zika Virus Syndrome is an entity composed by a variety of birth defects presented in newborns that have been exposed to the Zika Virus during pregnancy.

Here we present the case of a newborn with microcephaly whose mother presented a confirmed Zika Virus infection during the third trimester of pregnancy, despite of the evident findings and the history of Zika infection the RT-PCR in amniotic and cerebrospinal fluid of the newborn was negative. RT-PCR has demonstrated a low sensibility in samples with low viral loads, reason why, we propose a clinical diagnosis in patients with clinical history of Zika Virus infection during pregnancy accompanied by evident clinical manifestations of the child. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congenital" title="congenital">congenital</a>, <a href="https://publications.waset.org/abstracts/search?q=Zika%20virus" title=" Zika virus"> Zika virus</a>, <a href="https://publications.waset.org/abstracts/search?q=microcephaly" title=" microcephaly"> microcephaly</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20transcriptase%20polymerase%20chain%20reaction" title=" reverse transcriptase polymerase chain reaction"> reverse transcriptase polymerase chain reaction</a> </p> <a href="https://publications.waset.org/abstracts/84563/negative-rt-pcr-in-a-newborn-infected-with-zika-virus-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84563.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">211</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">97</span> Relationship and Comorbidity between Down Syndrome and Autism Spectrum Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Jim%C3%A9nez%20Lidue%C3%B1a">Elena Jiménez Lidueña</a>, <a href="https://publications.waset.org/abstracts/search?q=Noelia%20Santos%20Muriel"> Noelia Santos Muriel</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20L%C3%B3pez%20Resa"> Patricia López Resa</a>, <a href="https://publications.waset.org/abstracts/search?q=Noelia%20Pulido%20Garc%C3%ADa"> Noelia Pulido García</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Moraleda%20Sep%C3%BAlveda"> Esther Moraleda Sepúlveda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there has been a notable increase in the number of investigations that establish that Down Syndrome and Autism Spectrum Disorder are diagnoses that can coexist together. However, there are also many studies that consider that both diagnoses present neuropsychological, linguistic and adaptive characteristics with a totally different profiles. The objective of this research is to question whether there really can be a profile that encompasses both disorders or if they can be incompatible with each other. To this end, a review of the scientific literature of recent years has been carried out. The results indicate that the two lines collect opposite approaches. On the one hand, there is research that supports the increase in comorbidity between Down Syndrome and Autism Spectrum Disorder and, on the other hand, shows a totally different general development profile between the two. The discussion focuses on discussing both lines of work and on proposing future lines of research in this regard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Down%20Syndrome" title="Down Syndrome">Down Syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=Autism" title=" Autism"> Autism</a>, <a href="https://publications.waset.org/abstracts/search?q=comorbidity" title=" comorbidity"> comorbidity</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic" title=" linguistic"> linguistic</a> </p> <a href="https://publications.waset.org/abstracts/165225/relationship-and-comorbidity-between-down-syndrome-and-autism-spectrum-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165225.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">96</span> Numerical Analysis of a Mechanism for the Morphology in the Extrados of an Airfoil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20R.%20Jimenez%20Barron">E.

A previous work on morphology is continued where the 'initial' profile is the NACA 4415 and as a new profile 'objective' the FUSION. The objective of this work is the dimensioning of the elements of the mechanism used to achieve the required changes. We consulted the different materials used in the aeronautics industry, as well as new materials in this area that could contribute to the good performance of the mechanism without negatively affecting the aerodynamics. These results allow evaluating the performance of a wing with variable extrados with respect to the defined morphology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title="numerical analysis">numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanisms" title=" mechanisms"> mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=morphing%20airfoil" title=" morphing airfoil"> morphing airfoil</a>, <a href="https://publications.waset.org/abstracts/search?q=morphing%20wings" title=" morphing wings"> morphing wings</a> </p> <a href="https://publications.waset.org/abstracts/77600/numerical-analysis-of-a-mechanism-for-the-morphology-in-the-extrados-of-an-airfoil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77600.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">235</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">95</span> Numerical and Experimental Assessment of a PCM Integrated Solar Chimney</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Carlos%20Frutos%20Dordelly">J.

In the last two decades, the mounting concern of greenhouse gas emissions and the need for an efficient passive ventilation system have driven the development of new alternative passive technologies such as ventilated facades, trombe walls or solar chimneys. The objective of the study is the assessment of PCM panels in an in situ solar chimney for the establishment of a numerical model. The PCM integrated solar chimney shows slight performance improvement in terms of mass flow rate and external temperature and outlet temperature difference. An increase of 11.3659 m<sup>3</sup>/h can be observed during low wind speed periods. Additionally, the surface temperature across the chimney goes beyond 45 °C and allows the activation of PCM panels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title="energy storage">energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20ventilation" title=" natural ventilation"> natural ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20changing%20materials" title=" phase changing materials"> phase changing materials</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20chimney" title=" solar chimney"> solar chimney</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a> </p> <a href="https://publications.waset.org/abstracts/75922/numerical-and-experimental-assessment-of-a-pcm-integrated-solar-chimney" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75922.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">366</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">94</span> Intermodal Strategies for Redistribution of Agrifood Products in the EU: The Case of Vegetable Supply Chain from Southeast of Spain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20C.%20P%C3%A9rez-Mesa">Juan C.

In this regard, apart from other institutions, the European Commission (EC) has designed plans in recent years promoting a more sustainable transportation model in an attempt to ultimately shift traffic from the road to the sea by using intermodality to achieve a model rebalancing. This issue proves especially relevant in supply chains from peripheral areas of the continent, where the supply of certain agrifood products is high. In such cases, the most difficult challenge is managing perishable goods. This study focuses on new approaches that strengthen the modal shift, as well as the reduction of externalities. This problem is analyzed by attempting to promote intermodal system (truck and short sea shipping) for transport, taking as point of reference highly perishable products (vegetables) exported from southeast Spain, which is the leading supplier to Europe. Methodologically, this paper seeks to contribute to the literature by proposing a different and complementary approach to establish a comparison between intermodal and the “only road” alternative. For this purpose, the multicriteria decision is utilized in a p-median model (P-M) adapted to the transport of perishables and to a means of shipping selection problem, which must consider different variables: transit cost, including externalities, time, and frequency (including agile response time). This scheme avoids bias in decision-making processes. By observing the results, it can be seen that the influence of the externalities as drivers of the modal shift is reduced when transit time is introduced as a decision variable. These findings confirm that the general strategies, those of the EC, based on environmental benefits lose their capacity for implementation when they are applied to complex circumstances. In general, the different estimations reveal that, in the case of perishables, intermodality would be a secondary and viable option only for very specific destinations (for example, Hamburg and nearby locations, the area of influence of London, Paris, and the Netherlands). Based on this framework, the general outlook on this subject should be modified. Perhaps the government should promote specific business strategies based on new trends in the supply chain, not only on the reduction of externalities, and find new approaches that strengthen the modal shift. A possible option is to redefine ports, conceptualizing them as digitalized redistribution and coordination centers and not only as areas of cargo exchange. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20externalities" title="environmental externalities">environmental externalities</a>, <a href="https://publications.waset.org/abstracts/search?q=intermodal%20transport" title=" intermodal transport"> intermodal transport</a>, <a href="https://publications.waset.org/abstracts/search?q=perishable%20food" title=" perishable food"> perishable food</a>, <a href="https://publications.waset.org/abstracts/search?q=transit%20time" title=" transit time"> transit time</a> </p> <a href="https://publications.waset.org/abstracts/148707/intermodal-strategies-for-redistribution-of-agrifood-products-in-the-eu-the-case-of-vegetable-supply-chain-from-southeast-of-spain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148707.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">93</span> Building Information Modelling Implementation in the Lifecycle of Sustainable Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Scarlet%20Alejandra%20Romano">Scarlet Alejandra Romano</a>, <a href="https://publications.waset.org/abstracts/search?q=Joni%20Kareco"> Joni Kareco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The three pillars of sustainability (social, economic and environmental) are relevant concepts to the Architecture, Engineering, and Construction (AEC) industry because of the increase of international agreements and guidelines related to this topic during the last years. Considering these three pillars, the AEC industry faces important challenges, for instance, to decrease the carbon emissions (environmental challenge), design sustainable spaces for people (social challenge), and improve the technology of this field to reduce costs and environmental problems (economic and environmental challenge). One alternative to overcome these challenges is Building Information Modelling program (BIM) because according to several authors, this technology improves the performance of the sustainable buildings in all their lifecycle phases. The main objective of this paper is to explore and analyse the current advantages and disadvantages of the BIM implementation in the life-cycle of sustainable buildings considering the three pillars of sustainability as analysis parameters. The methodology established to achieve this objective is exploratory-descriptive with the literature review technique. The partial results illustrate that despite the BIM disadvantages and the lack of information about its social sustainability advantages, this software represents a significant opportunity to improve the three sustainable pillars of the sustainable buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modelling" title="building information modelling">building information modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20lifecycle%20analysis" title=" building lifecycle analysis"> building lifecycle analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20buildings" title=" sustainable buildings"> sustainable buildings</a> </p> <a href="https://publications.waset.org/abstracts/89629/building-information-modelling-implementation-in-the-lifecycle-of-sustainable-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89629.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">186</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">92</span> Voice Signal Processing and Coding in MATLAB Generating a Plasma Signal in a Tesla Coil for a Security System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Jimenez">Juan Jimenez</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Yambay"> Erika Yambay</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayana%20Pilco"> Dayana Pilco</a>, <a href="https://publications.waset.org/abstracts/search?q=Brayan%20Parra"> Brayan Parra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an investigation of voice signal processing and coding using MATLAB, with the objective of generating a plasma signal on a Tesla coil within a security system.

We could all agree that one of the objectives of Higher Education is to provide students with a variety of intellectual and practical skills that, at the same time, will help them develop competitive advantages such as adaptation and critical thinking. Among the strategic objectives of Universidad de Monterrey (UDEM) has been to provide flexibility and satisfaction to students in the delivery modes of the academic offer. UDEM implemented a methodology that combines face to face with synchronous and asynchronous as delivery modes. UDEM goal, in this case, was to implement new technologies and different teaching methodologies that will improve the students learning experience. In this study, the experience of students during courses implemented in new delivery mode was compared with students in courses with traditional delivery modes. Students chose openly either way freely. After everything students around the world lived in 2020 and 2021, one can think that the face to face (traditional) delivery mode would be the one chosen by students. The results obtained in this study reveal that both delivery modes satisfy students and favor their learning process. We will show how the combination of delivery modes provides flexibility, so the proposal is that universities can include them in their academic offer as a response to the current student's learning interests and needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexibility" title="flexibility">flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20delivery%20modes" title=" new delivery modes"> new delivery modes</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20satisfaction" title=" student satisfaction"> student satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20offer" title=" academic offer"> academic offer</a> </p> <a href="https://publications.waset.org/abstracts/164168/students-experience-perception-in-courses-taught-in-new-delivery-modes-compared-to-traditional-modes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164168.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">101</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">90</span> Diagnosis, Development, and Adoption of Technology Packages for Innovation in Precision Agriculture in the Wine Sector in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nivon%20P.%20Alejandra">Nivon P.

The growing development of the viticulture and wine sector in Mexico prospects an increase in its national market participation for 2020, this is the reason to consider it a fertile field for the technological packages adoption that promote Precision Agriculture (PA) in a harmonic and sustainable development. A viability inspection of technological packages adoption by viticulture and wine sector is made following the methodology proposed by SAGARPA in 2015 and the World Bank in 2008: the history, actors, strengths and opportunities are analyzed in this particular agroindustrial sector, also its technological innovation system is inspected in order to improve technological capacities and innovation networks taking into account local and regional resources. PA and technological packages adoption can help improving the conditions and quality of the grape for winemaking: increasing the wine's storage potential and its nutraceutical nature. The assertive diagnosis in vineyard opportunity areas will help the management of the crop by applying natural treatments at the right time in the right place. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technological%20packages" title="technological packages">technological packages</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20farming" title=" precision farming"> precision farming</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a> </p> <a href="https://publications.waset.org/abstracts/90307/diagnosis-development-and-adoption-of-technology-packages-for-innovation-in-precision-agriculture-in-the-wine-sector-in-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90307.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">89</span> Experimental Approach for Determining Hemi-Anechoic Characteristics of Engineering Acoustical Test Chambers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santiago%20Montoya-Ospina">Santiago Montoya-Ospina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20E.%20Jim%C3%A9nez-Mej%C3%ADa"> Raúl E.

Comparison between theoretical and experimental data yields to minimum error, giving satisfactory results for the hemi-anechoic characterization of the chamber. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20impedance" title="acoustic impedance">acoustic impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=finite-difference%20time-domain" title=" finite-difference time-domain"> finite-difference time-domain</a>, <a href="https://publications.waset.org/abstracts/search?q=hemi-anechoic%20characterization" title=" hemi-anechoic characterization"> hemi-anechoic characterization</a> </p> <a href="https://publications.waset.org/abstracts/86159/experimental-approach-for-determining-hemi-anechoic-characteristics-of-engineering-acoustical-test-chambers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86159.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">88</span> Relocation of the Air Quality Monitoring Stations Network for Aburrá Valley Based on Local Climatic Zones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carmen%20E.%20Zapata">Carmen E.

These modifications provoke changes in the temperature distribution known as “the heat island effect”. According to this phenomenon, we have the need to conceive the urban planning based on climatological patterns that will assure its sustainable functioning, including the particularities of the climate variability. In the present study, it is identified the Local Climate Zones (LCZ) in the Metropolitan Area of the Aburrá Valley (Colombia) with the objective of relocate the air quality monitoring stations as a partial solution to the problem of how to measure representative air quality levels in a city for a local scale, but with instruments that measure in the microscale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20quality" title="air quality">air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20climatic%20zones" title=" local climatic zones"> local climatic zones</a>, <a href="https://publications.waset.org/abstracts/search?q=valley" title=" valley"> valley</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20stations" title=" monitoring stations"> monitoring stations</a> </p> <a href="https://publications.waset.org/abstracts/49614/relocation-of-the-air-quality-monitoring-stations-network-for-aburra-valley-based-on-local-climatic-zones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49614.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">272</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">87</span> Jopara: Conversational Code Switching Between Spanish and Guarani a Sociolinguistic Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Alejandra%20Mareco">Maria Alejandra Mareco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to explore a communicative strategy used by Guaraní-Spanish bilingual speakers. It will be presented in English or Spanish. This strategy is conversational code-switching, which is used by people from rural as well as urban areas in Formosa, Argentina and Paraguay. Guarani is an Aboriginal Language that is the official language in Paraguay. Code-switching is a language-processing phenomenon that creates communicative and social meaning in a given community. This paper poses a broad question at the onset of this study: Spanish-Guaraní speakers tend to use four different conversational code-switching patterns in their oral alternations, these four categories being: quotation, addressee specification, reiteration, and interjections. Later, spoken data were prioritized in terms of their importance and potential impact on the hypothesis outlined. Different groups of people were observed in real-world settings. They consisted of fourteen proficient Spanish Guaraní bilingual speakers from different social groups and ages. Afterward, a group of informants was chosen to obtain a wide range of natural encounters. Informants were observed with special attention to their natural communication, particularly oral interactions. Furthermore, the relationship between interlocutors during code-switching, as based on a negotiation between them, was considered of most relevance. Results were evaluated according to the interpretative method by testing the co-occurrence of the four conversational categories described above. The testing instruments identified that the four aspects of Spanish Guaraní code-switching introduced above were applied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bilingualism" title="bilingualism">bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20switching" title=" code switching"> code switching</a>, <a href="https://publications.waset.org/abstracts/search?q=aboriginal%20language" title=" aboriginal language"> aboriginal language</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20contact" title=" language contact"> language contact</a> </p> <a href="https://publications.waset.org/abstracts/194124/jopara-conversational-code-switching-between-spanish-and-guarani-a-sociolinguistic-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194124.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">5</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">86</span> Perception of Violence through the Drawing: A Research with Mexican University Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yessica%20Martinez%20Soto">Yessica Martinez Soto</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20E.%20Jimenez%20Yanez"> Cesar E.

It is up to social scientists to be able to carry out analyzes in this regard to identify the different ways in which violence is normalized among people. The interest of this research work focuses on investigating the perception of violence in Mexican University students through the technique of drawing. To carry out this research, we worked with 67 university students from the Autonomous University of Baja California in Mexico, who drew an image of how they understood the concept of violence. His works showed us a variety of emotions, actions, and elements that relate and link with violence. One of the methodological tools to recognize and establish the link between the knowledge of a concept between discourse and practice is through graphic representations, that is, drawings. Although the drawing gives us a personal interpretation of the reality of each artist, the repetition of elements and the representation of similar situations allowed us to identify the degrees of incidence of the different types of violence and the areas in which it manifests itself. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=college%20students" title="college students">college students</a>, <a href="https://publications.waset.org/abstracts/search?q=Mexico" title=" Mexico"> Mexico</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20representations" title=" social representations"> social representations</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a> </p> <a href="https://publications.waset.org/abstracts/91278/perception-of-violence-through-the-drawing-a-research-with-mexican-university-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91278.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">232</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">85</span> Prevalence of Anxiety and Depression: A Descriptive Cross-Sectional Study among Individuals with Substance-Related Disorders in Argentina</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badino%20Manuel">Badino Manuel</a>, <a href="https://publications.waset.org/abstracts/search?q=Farias%20Mar%C3%ADa%20Alejandra"> Farias María Alejandra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anxiety and depression are considered the main mental health issues found in people with substance-related disorders. Furthermore, substance-related disorders, anxiety-related and depressive disorders are among the leading causes of disability and are associated with increased mortality. The co-occurrence of substance-related disorders and these mental health conditions affect the accuracy in diagnosis, treatment plan, and recovery process. The aim is to describe the prevalence of anxiety and depression in patients with substance-related disorders in a mental health service in Córdoba, Argentina. A descriptive cross-sectional study was conducted among patients with substance-related disorders (N=305). Anxiety and depression were assessed using the Patient Health Questionnaire-4 (PHQ-4) during the period from December 2021 to March 2022. For a total of 305 participants, 71,8% were male, 25,6% female and 2,6% non-binary. As regards marital status, 51,5% were single, 21,6% as a couple, 5,9% married, 15,4% separated and 5,6% divorced. In relation to education status, 26,2% finished university, 56,1% high school, 16,4% only primary school and 1,3% no formal schooling. Regarding age, 10,8% were young, 84,3% were adults, and 4,9% were elderly. In-person treatment represented 64,6% of service users, and 35,4% were conducted through teleconsultation. 15,7% of service users scored 3 or higher for anxiety, and 32,1% scored 3 or higher for depression in the PHQ-4. 13,1% obtained a score of 3 or higher for both anxiety and depression. It is recommended to identify anxiety and depression among patients with substance-related disorders to improve the quality of diagnosis, treatment, and recovery. It is suggested to apply PHQ-4, PHQ-9 within the protocol of care for these patients. <p class="card-text"><strong>Keywords:</strong> <a
