One part of it is so-called petty corruption, related to large-scale bribe giving by ordinary citizens trying to influence the works of public administration or public services. As it is with all means of corruption, petty corruption is related to the level of democracy (or administration efficiency) in a society. The developed model captures some of the factors related to corruptive behavior, as well as people’s attitude towards petty corruption. It has four basic elements: user’s perception of corruption in the society of interest, the influence of social interactions, the influence of penalizing mechanism, and influence of campaigns against petty corruption. The model is agent-based, developed in NetLogo, with a lot of random settings that provide a wider scope of responses. Interactions of different settings for variables of elements provide insight into the influence of each element on attitude towards petty corruption, as well as petty corruptive behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agent-based%20model" title="agent-based model">agent-based model</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=influence" title=" influence"> influence</a>, <a href="https://publications.waset.org/abstracts/search?q=petty%20corruption" title=" petty corruption"> petty corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=society" title=" society"> society</a> </p> <a href="https://publications.waset.org/abstracts/93444/modeling-influence-on-petty-corruption-attitudes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93444.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Application of the MOOD Technique to the Steady-State Euler Equations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaspar%20J.%20Machado">Gaspar J.

We will consider the unidimensional Burgers' equation as the reference case for the scalar situation and the unidimensional Euler equations for the vectorial situation. We consider two approaches to solve the nonlinear equations: a time marching algorithm and a direct steady-state approach. We first develop the necessary and sufficient conditions to obtain the existence and unicity of the solution. We treat regular examples and solutions with a steady shock and to provide very-high-order finite volume approximations we implement a method based on the MOOD technology (Multi-dimensional Optimal Order Detection). The main ingredient consists in using an 'a posteriori' limiting strategy to eliminate non physical oscillations deriving from the Gibbs phenomenon while keeping a high accuracy for the smooth part. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Euler%20equations" title="Euler equations">Euler equations</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20volume" title=" finite volume"> finite volume</a>, <a href="https://publications.waset.org/abstracts/search?q=MOOD" title=" MOOD"> MOOD</a>, <a href="https://publications.waset.org/abstracts/search?q=steady-state" title=" steady-state"> steady-state</a> </p> <a href="https://publications.waset.org/abstracts/52830/application-of-the-mood-technique-to-the-steady-state-euler-equations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52830.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">276</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> Algorithm for Path Recognition in-between Tree Rows for Agricultural Wheeled-Mobile Robots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Rocha">Anderson Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Miguel%20de%20Figueiredo%20Dinis%20Oliveira%20Gaspar"> Pedro Miguel de Figueiredo Dinis Oliveira Gaspar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Machine vision has been widely used in recent years in agriculture, as a tool to promote the automation of processes and increase the levels of productivity. The aim of this work is the development of a path recognition algorithm based on image processing to guide a terrestrial robot in-between tree rows. The proposed algorithm was developed using the software MATLAB, and it uses several image processing operations, such as threshold detection, morphological erosion, histogram equalization and the Hough transform, to find edge lines along tree rows on an image and to create a path to be followed by a mobile robot. To develop the algorithm, a set of images of different types of orchards was used, which made possible the construction of a method capable of identifying paths between trees of different heights and aspects. The algorithm was evaluated using several images with different characteristics of quality and the results showed that the proposed method can successfully detect a path in different types of environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20mobile%20robot" title="agricultural mobile robot">agricultural mobile robot</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=path%20recognition" title=" path recognition"> path recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=hough%20transform" title=" hough transform"> hough transform</a> </p> <a href="https://publications.waset.org/abstracts/96928/algorithm-for-path-recognition-in-between-tree-rows-for-agricultural-wheeled-mobile-robots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96928.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">146</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> True Single SKU Script: Applying the Automated Test to Set Software Properties in a Global Software Development Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Brigido">Antonio Brigido</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Meireles"> Maria Meireles</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Barros"> Francisco Barros</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaspar%20Mota"> Gaspar Mota</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20Terra"> Fernanda Terra</a>, <a href="https://publications.waset.org/abstracts/search?q=Lidia%20Melo"> Lidia Melo</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Reis"> Marcelo Reis</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Souza"> Camilo Souza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the globalization of the software process advances, companies are increasingly committed to improving software development technologies across multiple locations. On the other hand, working with teams distributed in different locations also raises new challenges. In this sense, automated processes can help to improve the quality of process execution. Therefore, this work presents the development of a tool called TSS Script that automates the sample preparation process for carrier requirements validation tests. The objective of the work is to obtain significant gains in execution time and reducing errors in scenario preparation. To estimate the gains over time, the executions performed in an automated and manual way were timed. In addition, a questionnaire-based survey was developed to discover new requirements and improvements to include in this automated support. The results show an average gain of 46.67% of the total hours worked, referring to sample preparation. The use of the tool avoids human errors, and for this reason, it adds greater quality and speed to the process. Another relevant factor is the fact that the tester can perform other activities in parallel with sample preparation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Android" title="Android">Android</a>, <a href="https://publications.waset.org/abstracts/search?q=GSD" title=" GSD"> GSD</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20testing%20tool" title=" automated testing tool"> automated testing tool</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20products" title=" mobile products"> mobile products</a> </p> <a href="https://publications.waset.org/abstracts/139796/true-single-sku-script-applying-the-automated-test-to-set-software-properties-in-a-global-software-development-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139796.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">317</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> Standalone Docking Station with Combined Charging Methods for Agricultural Mobile Robots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonor%20Varandas">Leonor Varandas</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20D.%20Gaspar"> Pedro D.

In this paper, two different charging methods for agricultural standalone docking stations are shown that will take into account various variants as field size and its irregularities, work’s nature to which the robot will perform, deadlines that have to be respected, among others. Its features also are dependent on the orchard, season, battery type and its technical specifications and cost. First charging base method focuses on wireless charging, presenting more benefits for small field. The second charging base method relies on battery replacement being more suitable for large fields, thus avoiding the robot stop for recharge. Existing many methods to charge a battery, the CC CV was considered the most appropriate for either simplicity or effectiveness. The choice of the battery for agricultural purposes is if most importance. While the most common battery used is Li-ion battery, this study also discusses the use of graphene-based new type of batteries with 45% over capacity to the Li-ion one. A Battery Management Systems (BMS) is applied for battery balancing. All these approaches combined showed to be a promising method to improve a lot of technical agricultural work, not just in terms of plantation and harvesting but also about every technique to prevent harmful events like plagues and weeds or even to reduce crop time and cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20mobile%20robot" title="agricultural mobile robot">agricultural mobile robot</a>, <a href="https://publications.waset.org/abstracts/search?q=charging%20methods" title=" charging methods"> charging methods</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20replacement%20method" title=" battery replacement method"> battery replacement method</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20charging%20method" title=" wireless charging method"> wireless charging method</a> </p> <a href="https://publications.waset.org/abstracts/96931/standalone-docking-station-with-combined-charging-methods-for-agricultural-mobile-robots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96931.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">148</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> Functional Yoghurt Enriched with Microencapsulated Olive Leaves Extract Powder Using Polycaprolactone via Double Emulsion/Solvent Evaporation Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tamer%20El-Messery">Tamer El-Messery</a>, <a href="https://publications.waset.org/abstracts/search?q=Teresa%20Sanchez-Moya"> Teresa Sanchez-Moya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruben%20Lopez-Nicolas"> Ruben Lopez-Nicolas</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaspar%20Ros"> Gaspar Ros</a>, <a href="https://publications.waset.org/abstracts/search?q=Esmat%20Aly"> Esmat Aly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Olive leaves (OLs), the main by-product of the olive oil industry, have a considerable amount of phenolic compounds. The exploitation of these compounds represents the current trend in food processing. In this study, OLs polyphenols were microencapsulated with polycaprolactone (PCL) and utilized in formulating novel functional yoghurt. PCL-microcapsules were characterized by scanning electron microscopy, and Fourier transform infrared spectrometry analysis. Their total phenolic (TPC), total flavonoid (TFC) contents, and antioxidant activities (DPPH, FRAP, ABTS), and polyphenols bioaccessibility were measured after oral, gastric, and intestinal steps of in vitro digestion. The four yoghurt formulations (containing 0, 25, 50, and 75 mg of PCL-microsphere/100g yoghurt) were evaluated for their pH, acidity, syneresis viscosity, and color during storage. In vitro digestion significantly affected the phenolic composition in non-encapsulated extract while had a lower impact on encapsulated phenolics. Higher protection was provided for encapsulated OLs extract, and their higher release was observed at the intestinal phase. Yoghurt with PCL-microsphere had lower viscosity, syneresis, and color parameters, as compared to control yoghurt. Thus, OLs represent a valuable and cheap source of polyphenols which can be successfully applied, in microencapsulated form, to formulate functional yoghurt. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=yoghurt%20quality%20attributes" title="yoghurt quality attributes">yoghurt quality attributes</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20leaves" title=" olive leaves"> olive leaves</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20and%20flavonoids%20compounds" title=" phenolic and flavonoids compounds"> phenolic and flavonoids compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=polycaprolactone%20as%20microencapsulant" title=" polycaprolactone as microencapsulant"> polycaprolactone as microencapsulant</a> </p> <a href="https://publications.waset.org/abstracts/135540/functional-yoghurt-enriched-with-microencapsulated-olive-leaves-extract-powder-using-polycaprolactone-via-double-emulsionsolvent-evaporation-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135540.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">142</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> Current Status and Future Trends of Mechanized Fruit Thinning Devices and Sensor Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20Lopes">Marco Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20D.%20Gaspar"> Pedro D.

The research should be committed towards selective methods, which inevitably need to incorporate some kinds of sensor technology. Computer vision often comes out as an obvious solution for unstructured detection problems, although leaves despite the chosen point of view frequently occlude fruits. Further research on non-traditional sensors that are capable of object differentiation is needed. Ultrasonic and Near Infrared (NIR) technologies have been investigated for applications related to horticultural produce and show a potential to satisfy this need while simultaneously providing spatial information as time of flight sensors. Light Detection and Ranging (LIDAR) technology also shows a huge potential but it implies much greater costs and the related equipment is usually much larger, making it less suitable for portable devices, which may serve a purpose on smaller unstructured orchards. Portable devices may serve a purpose on these types of orchards. In what concerns sensor methods, on-tree fruit detection, major challenge is to overcome the problem of fruits’ occlusion by leaves and branches. Hence, nontraditional sensors capable of providing some type of differentiation should be investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fruit%20thinning" title="fruit thinning">fruit thinning</a>, <a href="https://publications.waset.org/abstracts/search?q=horticultural%20field" title=" horticultural field"> horticultural field</a>, <a href="https://publications.waset.org/abstracts/search?q=portable%20devices" title=" portable devices"> portable devices</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20technologies" title=" sensor technologies"> sensor technologies</a> </p> <a href="https://publications.waset.org/abstracts/96932/current-status-and-future-trends-of-mechanized-fruit-thinning-devices-and-sensor-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96932.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">139</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> Characterization of Volatile Compounds in Meat Lamb Fed in Different Algeria Pasture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Berrighi">Nabila Berrighi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaddour%20Bouderoua"> Kaddour Bouderoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Khossif"> Maria Khossif</a>, <a href="https://publications.waset.org/abstracts/search?q=Gema%20Nieto"> Gema Nieto</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaspar%20Ros"> Gaspar Ros</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ruminant meat is an important source of nutrients and is also of high sensory value. However, the importance and nature of these characteristics depend on ruminant nutrition. The objective of this study is to assess the effect of two Algerian feeding systems applied in the steppic rearing area of Djelfa and in the highlands one of Tiaret on the growth performance of lambs and on their meat quality, especially on their aroma compounds of meat. At the beginning of the experiment, lambs had an average body weight of 34.04 kg, and 35.40 kg for the group reared at Highland (0% concentrate) and Steppe (30% concentrate), respectively. The incorporation of the concentrated feed in Steppe had a significant effect on slaughter weight compared to lambs fed only on pasture (Highland) (49.72 Kg vs. 42.06 Kg, P<0.05). Beyond the first month, animals from the Steppe one showed better weight gains compared to those from Highland (14.32Kg vs. 8.02 Kg, respectively, P<0,05). After slaughter, samples from the Longissimus thoracis were removed and analyzed. The results point to significant differences in the amounts of many of the predominant volatile compounds between both groups (p<0.05), such as Hexanal, 2-methyl-3-furanthiol and nonanal (8.92 μg/kg vs. 4.57 μg/kg), (8.88 μg/kg vs. 7.45 μg/kg) and (2.09 μ/kg vs. 1.02 μg/kg) associated with smells of green, boiling meat and orange fruit, respectively. These compounds, measured by olfactometry, derived from the oxidation of lipids and appear to be responsible for the characteristic flavor of lamb meat in the steppe compared to that generated by meat from animals from the Highland pastures. The Algerian Steppe ecosystem is very interesting for outdoor sheep breeding, which allows to obtain attractive sensory quality and in the production of typical lamb meat that can be considered as a label. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=falvour" title="falvour">falvour</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20performance" title=" growth performance"> growth performance</a>, <a href="https://publications.waset.org/abstracts/search?q=lamb%20meat" title=" lamb meat"> lamb meat</a>, <a href="https://publications.waset.org/abstracts/search?q=steppe%20pasture" title=" steppe pasture"> steppe pasture</a> </p> <a href="https://publications.waset.org/abstracts/158117/characterization-of-volatile-compounds-in-meat-lamb-fed-in-different-algeria-pasture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158117.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">4</span> Fast Return Path Planning for Agricultural Autonomous Terrestrial Robot in a Known Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlo%20Cernicchiaro">Carlo Cernicchiaro</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20D.%20Gaspar"> Pedro D.

The introduction of robotic solutions in this field is an increasingly researched topic to make the most of the Earth's resources, thus going to avoid the problems of wear and tear of the human body due to the harsh agricultural work, and open the possibility of a constant careful processing 24 hours a day. This project is realized for a terrestrial autonomous robot aimed to navigate in an orchard collecting fallen peaches below the trees. When it receives the signal indicating the low battery, it has to return to the docking station where it will replace its battery and then return to the last work point and resume its routine. Considering a preset path in orchards with tree rows with variable length by which the robot goes iteratively using the algorithm D*. In case of low battery, the D* algorithm is still used to determine the fastest return path to the docking station as well as to come back from the docking station to the last work point. MATLAB simulations were performed to analyze the flexibility and adaptability of the developed algorithm. The simulation results show an enormous potential for adaptability, particularly in view of the irregularity of orchard field, since it is not flat and undergoes modifications over time from fallen branch as well as from other obstacles and constraints. The D* algorithm determines the best route in spite of the irregularity of the terrain. Moreover, in this work, it will be shown a possible solution to improve the initial points tracking and reduce time between movements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=path%20planning" title="path planning">path planning</a>, <a href="https://publications.waset.org/abstracts/search?q=fastest%20return%20path" title=" fastest return path"> fastest return path</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20autonomous%20terrestrial%20robot" title=" agricultural autonomous terrestrial robot"> agricultural autonomous terrestrial robot</a>, <a href="https://publications.waset.org/abstracts/search?q=docking%20station" title=" docking station"> docking station</a> </p> <a href="https://publications.waset.org/abstracts/96930/fast-return-path-planning-for-agricultural-autonomous-terrestrial-robot-in-a-known-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96930.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">134</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> Safety and Maternal Anxiety in Mother's and Baby's Sleep: Cross-sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rayanne%20Branco%20Dos%20Santos%20Lima">Rayanne Branco Dos Santos Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorena%20Pinheiro%20Barbosa"> Lorena Pinheiro Barbosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Ferreira%20Lima"> Kamila Ferreira Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Manuel%20Tegoma%20Ruiz"> Victor Manuel Tegoma Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Monyka%20Brito%20Lima%20Dos%20Santos"> Monyka Brito Lima Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Wendiane%20Gueiros%20Gaspar"> Maria Wendiane Gueiros Gaspar</a>, <a href="https://publications.waset.org/abstracts/search?q=Luzia%20Camila%20Coelho%20Ferreira"> Luzia Camila Coelho Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Leandro%20Cardozo%20Dos%20Santos%20Brito"> Leandro Cardozo Dos Santos Brito</a>, <a href="https://publications.waset.org/abstracts/search?q=Deyse%20Maria%20Alves%20Rocha"> Deyse Maria Alves Rocha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The lack of regulation of the baby's sleep-wake pattern in the first years of life affects the health of thousands of women. Maternal sleep deprivation can trigger or aggravate psychosomatic problems such as depression, anxiety and stress that can directly influence maternal safety, with consequences for the baby's and mother's sleep. Such conditions can affect the family's quality of life and child development. Objective: To correlate maternal security with maternal state anxiety scores and the mother's and baby's total sleep time. Method: Cross-sectional study carried out with 96 mothers of babies aged 10 to 24 months, accompanied by nursing professionals linked to a Federal University in Northeast Brazil. Study variables were maternal security, maternal state anxiety scores, infant latency and sleep time, and total nocturnal sleep time of mother and infant. Maternal safety was calculated using a four-point Likert scale (1=not at all safe, 2=somewhat safe, 3=very safe, 4=completely safe). Maternal anxiety was measured by State-Trait Anxiety Inventory, state-anxiety subscale whose scores vary from 20 to 80 points, and the higher the score, the higher the anxiety levels. Scores below 33 are considered mild; from 33 to 49, moderate and above 49, high. As for the total nocturnal sleep time, values between 7-9 hours of sleep were considered adequate for mothers, and values between 9-12 hours for the baby, according to the guidelines of the National Sleep Foundation. For the sleep latency time, a time equal to or less than 20 min was considered adequate. It is noteworthy that the latency time and the time of night sleep of the mother and the baby were obtained by the mother's subjective report. To correlate the data, Spearman's correlation was used in the statistical package R version 3.6.3. Results: 96 women and babies participated, aged 22 to 38 years (mean 30.8) and 10 to 24 months (mean 14.7), respectively. The average of maternal security was 2.89 (unsafe); Mean maternal state anxiety scores were 43.75 (moderate anxiety). The babies' average sleep latency time was 39.6 min (>20 min). The mean sleep times of the mother and baby were, respectively, 6h and 42min and 8h and 19min, both less than the recommended nocturnal sleep time. Maternal security was positively correlated with maternal state anxiety scores (rh=266, p=0.009) and negatively correlated with infant sleep latency (rh= -0.30. P=0.003). Baby sleep time was positively correlated with maternal sleep time. (rh 0.46, p<0.001). Conclusion: The more secure the mothers considered themselves, the higher the anxiety scores and the shorter the baby's sleep latency. Also, the longer the baby sleeps, the longer the mother sleeps. Thus, interventions are needed to promote the quality and efficiency of sleep for both mother and baby. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sleep" title="sleep">sleep</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=infant" title=" infant"> infant</a>, <a href="https://publications.waset.org/abstracts/search?q=mother-child%20relations" title=" mother-child relations"> mother-child relations</a> </p> <a href="https://publications.waset.org/abstracts/167836/safety-and-maternal-anxiety-in-mothers-and-babys-sleep-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167836.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Solutions for Food-Safe 3D Printing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Geremew%20Geidare%20Kailo">Geremew Geidare Kailo</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20G%C3%A1sp%C3%A1r"> Igor Gáspár</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A1s%20Koris"> András Koris</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Paj%C4%8Din"> Ivana Pajčin</a>, <a href="https://publications.waset.org/abstracts/search?q=Fl%C3%B3ra%20Vit%C3%A1lis"> Flóra Vitális</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanja%20Vlajkov"> Vanja Vlajkov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Three-dimension (3D) printing, a very popular additive manufacturing technology, has recently undergone rapid growth and replaced the use of conventional technology from prototyping to producing end-user parts and products. The 3D Printing technology involves a digital manufacturing machine that produces three-dimensional objects according to designs created by the user via 3D modeling or computer-aided design/manufacturing (CAD/CAM) software. The most popular 3D printing system is Fused Deposition Modeling (FDM) or also called Fused Filament Fabrication (FFF). A 3D-printed object is considered food safe if it can have direct contact with the food without any toxic effects, even after cleaning, storing, and reusing the object. This work analyzes the processing timeline of the filament (material for 3D printing) from unboxing to the extrusion through the nozzle. It is an important task to analyze the growth of bacteria on the 3D printed surface and in gaps between the layers. By default, the 3D-printed object is not food safe after longer usage and direct contact with food (even though they use food-safe filaments), but there are solutions for this problem. The aim of this work was to evaluate the 3D-printed object from different perspectives of food safety. Firstly, testing antimicrobial 3D printing filaments from a food safety aspect since the 3D Printed object in the food industry may have direct contact with the food. Therefore, the main purpose of the work is to reduce the microbial load on the surface of a 3D-printed part. Coating with epoxy resin was investigated, too, to see its effect on mechanical strength, thermal resistance, surface smoothness and food safety (cleanability). Another aim of this study was to test new temperature-resistant filaments and the effect of high temperature on 3D printed materials to see if they can be cleaned with boiling or similar hi-temp treatment. This work proved that all three mentioned methods could improve the food safety of the 3D printed object, but the size of this effect variates. The best result we got was with coating with epoxy resin, and the object was cleanable like any other injection molded plastic object with a smooth surface. Very good results we got by boiling the objects, and it is good to see that nowadays, more and more special filaments have a food-safe certificate and can withstand boiling temperatures too. Using antibacterial filaments reduced bacterial colonies to 1/5, but the biggest advantage of this method is that it doesn’t require any post-processing. The object is ready out of the 3D printer.

While EDs provide a critical service, high use is indicative of inappropriate and inefficient healthcare. In Portugal, all ED have the Manchester Triage System (MTS), a clinical risk management tool to enable that patients are seen in order of clinical priority. In 2023, more than 40% of the ED visits were of non-urgent conditions (blue and green), that could be better managed in primary health care (PHC), meaning wrong use of resources and lack of health literacy. From 2017, the country has a phone line, SNS24 (Contact Centre of the National Health Service), for triage, counseling, and referral service, 24 hours/7 days a week. The pilot project ‘Call before, save lives’ was implemented in the municipalities of Póvoa de Varzim and Vila do Conde (around 150.000 residents), in May 2023, by the executive board of the Portuguese Health Service, with the support of the Shared Services of the Ministry of Health, and local authorities. This geographical area has short travel times, 99% of the population a family doctor and the region is organized in a health local unit (HLU), integrating PHC and the local hospital. The purposes of this project included to increase awareness to contact SNS 24, before going to an ED, and non-urgent conditions oriented to a family doctor, reducing ED visits. The implementation of the project involved two phases, beginning with: i) development of campaigns using local influencers (fishmonger, model, fireman) through local institutions and media; ii) provision of telephone installed on site to contact SNS24; iii) establishment of open consultation in PHC; iv) promotion of the use of SNS24; v) creation of acute consultations at the hospital for complex chronic patients; and vi) direct referral for home hospitalization by PHC. The results of this project showed an excellent level of access to SNS24, an increase in the number of users referred to ED, with great satisfaction of users and professionals. The second phase, initiated in January 2024, for access to the ED, the need for prior referral was established as an admission rule, except for certain situations, as trauma patients. If the patient refuses, their registration in the ED and subsequent screening in accordance with the MTS must be ensured. When the patient is non-urgent, shall not be observed in the ED, provided that, according to his clinical condition, is guaranteed to be referred to PHC or to consultation/day hospital, through effective scheduling of an appointment for the same or the following day. In terms of results, 8 weeks after beginning of phase 2, we assist of a decrease in self-reported patients to ED from 59% to 15%, and a reduction of around 7% of ED visits. The key for this success was an effective public campaign that increases the knowledge of the right use of the health system, and capable of changing behaviors. <p
