plastic user behind packaging, accounting for 16% of plastic production. Building and construction is also by far the largest user of one of the most impactful plastics, polyvinyl chloride (aka vinyl or PVC), accounting for 69% of PVC production. Building materials also have an outsized contribution to plastic pollution, including microplastic pollution. Yet building materials are often overlooked in plastic waste and pollution reduction efforts. Habitable will present a plastics and petrochemical analysis of over 250 common building material types and demonstrate how changes to building material selection towards safer, renewable, and lower carbon materials can reduce global consumption of plastics and associated pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20materials" title="building materials">building materials</a>, <a href="https://publications.waset.org/abstracts/search?q=fenceline%20communities" title=" fenceline communities"> fenceline communities</a>, <a href="https://publications.waset.org/abstracts/search?q=microplastics" title=" microplastics"> microplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=safer%20alternatives" title=" safer alternatives"> safer alternatives</a>, <a href="https://publications.waset.org/abstracts/search?q=embodied%20carbon" title=" embodied carbon"> embodied carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20analysis" title=" life cycle analysis"> life cycle analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=petrochemicals" title=" petrochemicals"> petrochemicals</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a> </p> <a href="https://publications.waset.org/abstracts/190126/prevalence-of-plastic-use-in-building-and-construction-an-analysis-of-250-common-building-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190126.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">23</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">926</span> Condom Attitudes and Self-Efficacy: Unwrapping Safer Sex Practices among Heterosexual Bahamian Men</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theresa%20Adderley">Theresa Adderley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Aside from abstinence, correct and consistent use of latex condoms is the best known effective method to reduce HIV transmission among sexually active heterosexual individuals. When condoms are correctly used, the risk of HIV transmission is reduced by approximately 85%, relative to risk when not protected during sexual intercourse. The literature provides evidence that heterosexual young adults continue to be the group among whom STI rates are highest and the group that engages in more sexual risk-taking behaviors such as inconsistent or no condom usage. This study examines condom attitudes, condom use self-efficacy and their contributions to safer sex behaviors among heterosexual men living in The Bahamas. Methods: Guided by the Theory of Planned Behavior, and a convenience sample of 185 heterosexual males (Mage= 31.95, SD = 11.35), three standardized instruments were used to assess behaviors that may not only place heterosexual males at risk for HIV infection but also their female partners. Results: The results of this study suggest that condom attitudes, and condom use self-efficacy are important in explaining 24% variance in safer sex behaviors among Bahamian men. Income (β= -.15, p < .01; condom attitudes, (β= .36, p < .01), and condom use self-efficacy (β= .1, p < .01) were significantly associated with safer sex behaviors. Conclusion: Rather than focusing only on the use of safer sex behaviors, an effective HIV prevention strategy must consider condom attitudes and condom use self-efficacy as specific variables that may contribute to perpetuating the transmission of HIV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condom%20attitudes" title="condom attitudes">condom attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=safer%20sex%20behaviors" title=" safer sex behaviors"> safer sex behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=condom%20self-efficacy" title=" condom self-efficacy"> condom self-efficacy</a> </p> <a href="https://publications.waset.org/abstracts/61537/condom-attitudes-and-self-efficacy-unwrapping-safer-sex-practices-among-heterosexual-bahamian-men" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61537.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">298</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">925</span> The Asia-European Union (EU) Traffic Safety Benchmarking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazwan%20Al-Haji">Ghazwan Al-Haji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traffic safety has become a major concern in Southeast Asia due to the increasing number of road accidents resulting in fatalities and injuries. Southeast Asia has one of the highest road traffic fatality rates in the world, in terms of both population and number of cars, nearly six times higher than the EU region. One of the reasons for this concerning trend is the increasing share of motorcycles as a form of transportation throughout Southeast Asia. The purpose of this study is to benchmark traffic safety situations and statistics in six countries in Asia and the EU, which Indonesia, Malaysia, Vietnam, Italy, Portugal and Sweden. The research will assess the priorities and causes of road accidents in the target nations. Further, the study will analyze the existing practices and promote best practices that can be implemented toward safer roads in Asian target countries. In order to achieve this goal, the study categorizes various factors contributing to traffic accidents and best practices into 4 pillars (Safer Behavior, Safer Roads, Safer Vehicles and Road Safety Management). The result of the study consists of a list of recommendations that can be applied by policymakers to promote safer roads in Asia towards 2030. The study is co-financed by the EU project ASIASAFE. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traffic%20safety" title="traffic safety">traffic safety</a>, <a href="https://publications.waset.org/abstracts/search?q=ASIASAFE" title=" ASIASAFE"> ASIASAFE</a>, <a href="https://publications.waset.org/abstracts/search?q=Southeast%20Asia" title=" Southeast Asia"> Southeast Asia</a>, <a href="https://publications.waset.org/abstracts/search?q=EU%20project" title=" EU project"> EU project</a> </p> <a href="https://publications.waset.org/abstracts/166078/the-asia-european-union-eu-traffic-safety-benchmarking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166078.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">69</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">924</span> Coastal Erosion Control Alternatives with Geosynthetics: Study Case of Ponta Negra Beach, Natal, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Medeiros">M.

As an important stage of any Civil Engineering project, literature review is necessary in order to evaluate these alternatives and to guide the decisions. Ponta Negra beachfront has a very intensive urban pressure. In addition, a very short sand area induces high intensity erosion processes. Different attempts of solving the problem were already built. However, erosion issues are still an important concern since these structures collapsed. Geosynthetics present a great potential to be applied in this area. In order to study coastal erosion control alternatives with the use of geosynthetics, this paper presents a literature review about this subject. Several studies were collected in which beach conditions are similar to those found in Ponta Negra beach. It was possible to evaluate the alternatives that might be used in the area. Further studies include the application of such techniques in pilot areas and the evaluation of the erosion process. Finally, the best alternative for futures studies on Ponta Negra beach is geocontainers of geotextiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geosynthetics" title="geosynthetics">geosynthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20erosion%20control" title=" coastal erosion control"> coastal erosion control</a>, <a href="https://publications.waset.org/abstracts/search?q=alternatives" title=" alternatives"> alternatives</a>, <a href="https://publications.waset.org/abstracts/search?q=Ponta%20Negra%20beach" title=" Ponta Negra beach"> Ponta Negra beach</a> </p> <a href="https://publications.waset.org/abstracts/99716/coastal-erosion-control-alternatives-with-geosynthetics-study-case-of-ponta-negra-beach-natal-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99716.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">152</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">923</span> A Fuzzy Hybrıd Decısıon Support System for Naval Base Place Selectıon in a Foreıgn Country</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latif%20Yanar">Latif Yanar</a>, <a href="https://publications.waset.org/abstracts/search?q=Muharrem%20Ka%C3%A7an"> Muharrem Kaçan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, an Analytic Hierarchy Process and Analytic Network Process Decision Support System (DSS) model for determination of a navy base place in another country is proposed together with a decision support software (DESTEC 1.0) developed using C Sharp programming language. The proposed software also has the ability of performing the fuzzy models (Fuzzy AHP and Fuzzy ANP) of the proposed DSS to cope with the ambiguous and linguistic nature of the model. The AHP and ANP model, for a decision support for selecting the best place among the alternatives, including the criteria and alternatives, is developed and solved by the experts from Turkish Navy and Turkish academicians related to international relations branches of the universities in Turkey. Also, the questionnaires used for weighting of the criteria and the alternatives are filled by these experts.Some of our alternatives are: economic and political stability of the third country, the effect of another super power in that country, historical relations, security in that country, social facilities in the city in which the base will be built, the transportation security and difficulty from a main city that have an airport to the city will have the base etc. Over 20 criteria like these are determined which are categorized in social, political, economic and military aspects. As a result all the criteria and three alternatives are evaluated by different people who have background and experience to weight the criteria and alternatives as it must be in AHP and ANP evaluation system. The alternatives got their degrees all between 0 – 1 and the total is 1. At the end the DSS advices one of the alternatives as the best one to the decision maker according to the developed model and the evaluations of the experts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytic%20hierarchical%20process" title="analytic hierarchical process">analytic hierarchical process</a>, <a href="https://publications.waset.org/abstracts/search?q=analytic%20network%20process" title=" analytic network process"> analytic network process</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=naval%20base%20place%20selection" title=" naval base place selection"> naval base place selection</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20criteria%20decision%20making" title=" multiple criteria decision making"> multiple criteria decision making</a> </p> <a href="https://publications.waset.org/abstracts/7968/a-fuzzy-hybrid-decision-support-system-for-naval-base-place-selection-in-a-foreign-country" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7968.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">391</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">922</span> Mitigating Biofouling on Reverse Osmosis Membranes: Applying Greener Preservatives to Biofilm Treatment </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Curtin">Anna Curtin</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20%20Thibodeau"> Matthew Thibodeau</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Buckley"> Heather Buckley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water scarcity is characterized by a lack of access to clean and affordable drinking water, as well as water for hygienic and economic needs. The amount of people effected by water scarcity is expected to increase in the coming years due to climate change, population growth, and pollution, amongst other things. In response, scientists are pursuing cost effective drinking water treatment methods, often with a focus on alternative water sources. Desalination of seawater via reverse osmosis is one promising alternative method. Desalination of seawater via reverse osmosis, however, is limited significantly by biofouling of the filtration membrane. Biofouling is the buildup of microorganisms in a biofilm at the water-membrane interface. It clogs the membrane, decreasing the efficiency of filtration, consequently increasing operational and maintenance costs. Although effective, existing chemical treatment methods can damage the membrane, decreasing the lifespan of the membrane; create antibiotic resistance; and cause harm to humans and the environment if they pass through the membrane into the permeate. The current project focuses on applying safer preservatives used in home and personal care products to RO membranes to investigate the biofouling treatment efficacy. Currently, many of these safer preservatives have only been tested on cells in planktonic phase in suspension cultures, not on cells in biofilms. The results of suspension culture tests are not applicable to biofouling scenarios because organisms in planktonic phase in suspension cultures exhibit different morphological, chemical, and metabolic characteristics than those in a biofilm. Testing antifoulant efficacy of safer preservatives on biofilms will provide more applicable results to biofouling on RO membranes. To do this, biofilms will be grown on 96-well-plates and minimum inhibitory concentrations (MIC90) and log-reductions will be calculated for various safer preservatives. Results from these tests will be used to guide doses for tests of safer preservatives in a bench-scale RO system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reverse%20osmosis" title="reverse osmosis">reverse osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=biofouling" title=" biofouling"> biofouling</a>, <a href="https://publications.waset.org/abstracts/search?q=preservatives" title=" preservatives"> preservatives</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=safer%20alternative" title=" safer alternative"> safer alternative</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a> </p> <a href="https://publications.waset.org/abstracts/122887/mitigating-biofouling-on-reverse-osmosis-membranes-applying-greener-preservatives-to-biofilm-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122887.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">921</span> Development of Boro-Tellurite Glasses Enhanced with HfO2 for Radiation Shielding: Examination of Optical and Physical Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sleman%20Yahya%20Rasul">Sleman Yahya Rasul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to their transparency, various types of glass are utilized in numerous applications where clear visibility is essential. One such application involves environments where radiography, radiotherapy, and X-ray devices are used, all of which involve exposure to radiation. As is well-known, radiation can be lethal to humans. Consequently, there is a need for glass that can absorb and block these harmful rays in such settings. Effective protection from radiation typically requires materials with high atomic numbers and densities. Currently, lead oxide-infused glasses are commonly used for this purpose, but due to the toxicity of lead oxide, there is a demand for safer alternatives. HfO2 has been selected as an additive for boro-tellurite (M1-M2-M3) glasses intended for radiation shielding because it has a high atomic number, high density, and is non-toxic. In this study, new glasses will be developed as alternatives to leaded glasses by incorporating x mol% HfO2 into the boro-tellurite glass structure. The glass compositions will be melted and quenched using the traditional method in an alumina crucible at temperatures between 900–1100°C. The resulting glasses will be evaluated for their elastic properties (including elastic modulus, shear modulus, bulk modulus, and Poisson ratio), density, hardness, and fracture toughness. X-ray diffraction (XRD) will be used to examine the amorphous nature of the glasses, while Differential Thermal Analysis (DTA) will provide thermal analysis. Optical properties will be assessed through UV-Vis and Photoluminescence Spectroscopy, and structural properties will be studied using Raman spectroscopy and FTIR spectroscopy. Additionally, the radiation shielding capabilities will be investigated by measuring parameters such as mass attenuation coefficient, half-value thickness, mean free path, effective atomic number (Z_eff), and effective electron density (N_e). The aim of this study is to develop new, lead-free glasses with excellent optical properties and high mechanical strength to replace the leaded glasses currently used for radiation shielding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boro-tellurite%20glasses" title="boro-tellurite glasses">boro-tellurite glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=hfo2" title=" hfo2"> hfo2</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20shielding" title=" radiation shielding"> radiation shielding</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20properties" title=" elastic properties"> elastic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20properties" title=" optical properties"> optical properties</a> </p> <a href="https://publications.waset.org/abstracts/186303/development-of-boro-tellurite-glasses-enhanced-with-hfo2-for-radiation-shielding-examination-of-optical-and-physical-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186303.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">43</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">920</span> Discrete Choice Modeling in Education: Evaluating Early Childhood Educators’ Practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michalis%20Linardakis">Michalis Linardakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilis%20Grammatikopoulos"> Vasilis Grammatikopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Athanasios%20Gregoriadis"> Athanasios Gregoriadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalliopi%20Trouli"> Kalliopi Trouli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Discrete choice models belong to the family of Conjoint analysis that are applied on the preferences of the respondents towards a set of scenarios that describe alternative choices.

One of the advantages of discrete choice models compared to other more traditional data collection methods (e.g. questionnaires and interviews that use ratings) is that the respondent is called to select among competitive and realistic alternatives, rather than objectively rate each attribute that the alternatives may have. We present the effort to construct and choose representative attributes that would cover all possible choices of the respondents, and the scenarios that have arisen. For the purposes of the study, we used a sample of 50 preschool educators in Greece that responded to 4 scenarios (from the total of 16 scenarios that the orthogonal design resulted), with each scenario having three alternative teaching practices. Seven attributes of the alternatives were used in the scenarios. For the analysis of the data, we used multinomial logit model with random effects, multinomial probit model and generalized mixed logit model. The conclusions drawn from the estimated parameters of the models are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conjoint%20analysis" title="conjoint analysis">conjoint analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20choice%20models" title=" discrete choice models"> discrete choice models</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20data" title=" educational data"> educational data</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20statistical%20analysis" title=" multivariate statistical analysis"> multivariate statistical analysis</a> </p> <a href="https://publications.waset.org/abstracts/27531/discrete-choice-modeling-in-education-evaluating-early-childhood-educators-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27531.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">465</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">919</span> Development of an Interactive Display-Control Layout Design System for Trains Based on Train Drivers’ Mental Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyeonkyeong%20Yang">Hyeonkyeong Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Minseok%20Son"> Minseok Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Taekbeom%20Yoo"> Taekbeom Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Woojin%20Park"> Woojin Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human error is the most salient contributing factor to railway accidents. To reduce the frequency of human errors, many researchers and train designers have adopted ergonomic design principles for designing display-control layout in rail cab. There exist a number of approaches for designing the display control layout based on optimization methods. However, the ergonomically optimized layout design may not be the best design for train drivers, since the drivers have their own mental models based on their experiences. Consequently, the drivers may prefer the existing display-control layout design over the optimal design, and even show better driving performance using the existing design compared to that using the optimal design. Thus, in addition to ergonomic design principles, train drivers’ mental models also need to be considered for designing display-control layout in rail cab. This paper developed an ergonomic assessment system of display-control layout design, and an interactive layout design system that can generate design alternatives and calculate ergonomic assessment score in real-time. The design alternatives generated from the interactive layout design system may not include the optimal design from the ergonomics point of view. However, the system’s strength is that it considers train drivers’ mental models, which can help generate alternatives that are more friendly and easier to use for train drivers. Also, with the developed system, non-experts in ergonomics, such as train drivers, can refine the design alternatives and improve ergonomic assessment score in real-time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=display-control%20layout%20design" title="display-control layout design">display-control layout design</a>, <a href="https://publications.waset.org/abstracts/search?q=interactive%20layout%20design%20system" title=" interactive layout design system"> interactive layout design system</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20model" title=" mental model"> mental model</a>, <a href="https://publications.waset.org/abstracts/search?q=train%20drivers" title=" train drivers"> train drivers</a> </p> <a href="https://publications.waset.org/abstracts/52550/development-of-an-interactive-display-control-layout-design-system-for-trains-based-on-train-drivers-mental-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52550.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">306</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">918</span> Psychoeducation to Prevent Spread of HIV Among Men Who Have Sex with Men in Surabaya City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christina%20Albertina%20Ludwinia%20Parung">Christina Albertina Ludwinia Parung</a>, <a href="https://publications.waset.org/abstracts/search?q=I%20Gusti%20Ayu%20Maya%20Vratasti"> I Gusti Ayu Maya Vratasti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sexual transmission of HIV among Men who have Sex with Men (MSM) is believed to be one of the sources of the AIDS epidemic. Nowadays, government, communities, and NGOs are taking action to prevent its spread by assisting and educating groups of MSM in their countries. This assistance involves experts in many fields of study, including psychology. In the field of psychology, psychoeducation is believed to be one of the ways to assist the MSM groups. Just like in other countries, this psychoeducation assistance is also needed in Indonesia, where MSM groups are found in many cities within. Surabaya, as the second largest and densely populated city in Indonesia, is known to have a big number of MSM population. In September to December 2020, the author and a colleague conducted a mentoring effort to the MSM community at the MSM community gathering location called Gang Pattaya, in the city of Surabaya. The existence of this community is disguised by the general public, but is well known by NGOs. Community members do MSM out of their liking, although some do it in exchange for money. However, safety factors, such as using condoms for MSM, are not a priority for this community. They do MSM whether they receive a reward or not, just out of a boost of pleasure. There is no attempt to find out the health of the partner once they are attracted to each other. In general, they do not know whether they are infected with HIV. Most of them feel healthy and since they do not show any symptoms, they think it is not necessary to get tested. In the mentoring process, the researchers conduct psychoeducation, which begins with an approach to certain individuals so that they are comfortable with the researchers’ presence, then increasing awareness of safe sex behavior for HIV prevention for groups in the form of counseling using the Theory of Reasoned Action (TRA) approach. Counseling is carried out in various forms including roleplay, games, and seminars. The number of participants was 11 people, varying from 19-47 years old. Pretest related to knowledge of safe sex was carried out before conducting the intervention and post-test after the intervention. The normality test used is the Shapiro-Wilk analysis. Different tests on the data obtained were carried out using the non-parametric Wilcoxon Signed Ranks Test. None of the participants had lower post-test knowledge scores than the pre-test. Prestest and post test for safer sex behavior showed 2 participants with safer sex behavior did not change. Both belong to the senior group, while other participants have an improvement in their safer sex behavior. These findings suggest that intervention programs for MSM as an effort to reduce HIV transmission should pay attention to affective and cognitive coping strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HIV" title="HIV">HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=men%20who%20have%20sex%20with%20men" title=" men who have sex with men"> men who have sex with men</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoeducation" title=" psychoeducation"> psychoeducation</a>, <a href="https://publications.waset.org/abstracts/search?q=psychology%20health" title=" psychology health"> psychology health</a>, <a href="https://publications.waset.org/abstracts/search?q=safer%20sex%20behavior" title=" safer sex behavior"> safer sex behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20reasoned%20action" title=" theory of reasoned action"> theory of reasoned action</a> </p> <a href="https://publications.waset.org/abstracts/134232/psychoeducation-to-prevent-spread-of-hiv-among-men-who-have-sex-with-men-in-surabaya-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134232.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">917</span> The Role of the General Budget in the Agricultural and Rural Development as an Alternative Economic outside the Hydrocarbons Sector </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kherbache%20Radhwane">Kherbache Radhwane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is concerned with the nature of the strategy of agricultural and rural development, through the fiscal policy adopted by the government throughout programs included in the general budget of the state represented in the national program of agricultural and rural development.

In general, however, optimizing two or more performance factors confronts the limits of time and computational tools. The optimization phase typically repeats infinitely until a series of processes that generate alternatives and analyze the generated alternatives achieve the desired performance. In particular, as complex geometry or precision increases, computational resources and time are prohibitive to find the required performance, so an optimization methodology is needed to deal with this. Instead of directly analyzing all the alternatives in the optimization process, applying experimental techniques (heuristic method) learned through experimentation and experience can reduce resource waste. This study proposes and verifies a method to optimize the double envelope of a building composed of a perforated panel using machine learning to the design geometry and quantitative performance. The proposed method is to achieve the required performance with fewer resources by supplementing the existing method which cannot calculate the complex shape of the perforated panel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20envelope" title="building envelope">building envelope</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=perforated%20metal" title=" perforated metal"> perforated metal</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-factor%20optimization" title=" multi-factor optimization"> multi-factor optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=fa%C3%A7ade" title=" façade"> façade</a> </p> <a href="https://publications.waset.org/abstracts/81902/multi-factor-optimization-method-through-machine-learning-in-building-envelope-design-focusing-on-perforated-metal-facade" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81902.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">224</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">915</span> Assessing Water Bottle Consumption on College Campus in Abu Dhabi: Towards a Sustainable Future</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ludmilla%20Wikkeling-Scott">Ludmilla Wikkeling-Scott</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Karim"> Amira Karim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In a rapidly developing environment, concerns for pollution and depletion of natural resources are challenges facing global communities. A major source of waste on university campuses is the use of plastic bottles, while cost of production and processing is high. Consumer demand stimulates popularity of plastic bottle production, but researchers agree this is not a sustainable solution. This pilot study assesses plastic water bottle used and attitude towards alternatives among Emirati college students. Methods: This study was conducted in December 2016, using an anonymous self-administered survey of 17 questions. The survey included personal characteristics, plastic water bottle used, attitude towards alternative replacement and sustainability. For statistical analysis, STATA 14C was used to determine significance of association. Results: A total of 500 Emirati students (94.6% female) completed the survey. Of the students, 82.6% preferred bottled water over tap water, and 44.6% reported disposable bottled water use in their household, 42.6% purchased disposable bottled water more than twice a week, and 44.2% purchased bottled water at least once, while on campus. Students were willing to consider switching to alternative water bottle use if it was more convenient (22.54%), cost less (55.13%) or improved the taste (22.54%), while only 7.85% students would not consider any alternatives. There was a significant difference in attitude towards alternatives to water bottle use by area of study (p < 0.005). Conclusion: The UAE strives to be at the forefront of sustainable development and protecting biodiversity. However, a major challenge is the increasing amount of waste, exacerbated by the increasing consumer demand for convenience as seen in this billion-dollar industry. Plastic bottles, for all purposes, pose a serious threat to the environment and sustainable campus initiatives can help reduce the ecological footprint, improve awareness of safe alternatives and benefits to the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20foot%20print" title="ecological foot print">ecological foot print</a>, <a href="https://publications.waset.org/abstracts/search?q=emirati%20students" title=" emirati students"> emirati students</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20bottle%20consumption" title=" plastic bottle consumption"> plastic bottle consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20campus" title=" sustainable campus"> sustainable campus</a> </p> <a href="https://publications.waset.org/abstracts/72272/assessing-water-bottle-consumption-on-college-campus-in-abu-dhabi-towards-a-sustainable-future" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">914</span> Coastal Cliff Protection in Beit Yanai, Israel: Examination of Alternatives and Public Preference Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tzipi%20Eshet">Tzipi Eshet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary objectives of this work are the examination of public preferences and attributed importance to different characteristics of coastal cliff protection alternatives, and drawing conclusions about the applicable alternative in Beit-Yanai beach. Erosion of coastal cliffs is a natural phenomenon that occurs in many places in the world. This creates problems along the coastlines, which are densely populated areas with highly developed economic activity. In recent years, various aspects of the aeolianite cliffs along the Israeli coast have been studied extensively. There is a consensus among researchers regarding a general trend of cliff retreat. This affects civilian infrastructure, wildlife habitats and heritage values, as well as Increases the risk to human life. The Israeli government, committed to the integrated coastal zones management approach, decided on a policy and guidelines to deal with cliff erosion, which includes establishing physical protection on land and in the sea, sand nourishment and runoff drainage. Physical protection solutions to reduce the rate of retreat of the cliffs are considerably important both for planning authorities and visitors to the beach. Direct costs of different protection alternatives, as well as external costs and benefits, may vary, thus affecting consumer preferences. Planning and execution of sustainable coastal cliff protection alternatives must take into account the different characteristics and their impact on aspects of economics, environment and leisure. The rocky shore of Beit-Yanai Beach was chosen as a case study to examine the nature of the influence of various protective solutions on consumer preferences. This beach is located in the center of Israel's coastline, and acts as a focus of attraction for recreation, land and sea sports, and educational activities as well. If no action will be taken, cliff retreat will continue. A survey was conducted to reveal the importance of coastal protection alternatives characteristics and the visual preferences to visitors at beach Beit-Yanai and residents living on the cliff (N=287). Preferences and willingness-to-pay were explored using Contingent-Ranking and Choice-Experiments techniques. Results show that visitors’ and residents’ willingness-to-pay for coastal cliff protection alternatives is affected both by financial and environmental aspects, as well as leisure. They prefer coastal cliff protection alternatives that are not visible and do not need constant maintenance, do not affect the quality of seawater or the habitats of wildlife and do not lower the security level of the swimmers. No significant difference was found comparing willingness-to-pay among local and non-local users. Additionally, they mostly prefer a protection solution which is integrated in the coastal landscape and maintains the natural appearance of the beach. Of the possible protection alternatives proposed for the protection of the cliff in Beit Yanai beach are two techniques that meet public preferences: rock revetments and submerged detached breakwaters. Results indicate that the visiting public prefer the implementation of these protection alternatives and will be willing to pay for them. Future actions to reduce retreat rate in Beit-Yanai have to consider implications on the economic, environmental and social conditions, along with weighting public interest against the interest of the individual. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contingent-ranking" title="contingent-ranking">contingent-ranking</a>, <a href="https://publications.waset.org/abstracts/search?q=choice-experiments" title=" choice-experiments"> choice-experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20cliff%20protection" title=" coastal cliff protection"> coastal cliff protection</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion%20of%20coastal%20cliffs" title=" erosion of coastal cliffs"> erosion of coastal cliffs</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment "> environment </a> </p> <a href="https://publications.waset.org/abstracts/30624/coastal-cliff-protection-in-beit-yanai-israel-examination-of-alternatives-and-public-preference-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30624.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">306</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">913</span> Toward an Integrated Safe and Sustainable Food System: A General Overview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erkan%20Rehber">Erkan Rehber</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Vural"> Hasan Vural</a>, <a href="https://publications.waset.org/abstracts/search?q=Sule%20Turhan"> Sule Turhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is a fact that food is a vital need of human beings.

The remediation of mixture of pesticides is a challenging affair regarding inadvertent mixture of pesticides from agricultural lands treated with various compounds. Global concerns about the excessive use of pesticides have driven the need to develop more effective and safer alternatives for their remediation. We focused our work on the microbial degradation of a mixture of three Type II-pyrethroids, namely Cypermethrin, Cyhalothrin and Deltamethrin commonly applied for both agricultural and domestic purposes. The fungal strains (Fusarium strain 8-11P and Fusarium sp. zzz1124) had previously been isolated from agricultural soils and their ability to biotransform this amalgam was studied. In brief, the experiment was conducted in two growth systems (added carbon and carbon-free) enriched with variable concentrations of pyrethroids between 100 to 300 mgL⁻¹. Parameter optimization (pH, temperature, concentration and time) was done using a central composite design matrix of Response Surface Methodology (RSM). At concentrations below 200 mgL⁻¹, complete removal was observed; however, degradation of 95.6%/97.4 and 92.27%/95.65% (in carbon-free/added carbon) was observed for 250 and 300 mgL⁻¹ respectively. The consortium has been shown to degrade the pyrethroid mixture (300 mg L⁻¹) within 120 h. After 5 day incubation, the residual pyrethroids concentration in unsterilized soil were much lower than in sterilized soil, indicating that microbial degradation predominates in pyrethroids elimination with the half-life (t₁/₂) of 1.6 d and R² ranging from 0.992-0.999. Overall, these results showed that microbial consortia might be more efficient than single degrader strains. The findings will complement our current understanding of the bioremediation of mixture of Type II pyrethroids with microbial consortia and potentially heighten the importance for considering bioremediation as an effective alternative for the remediation of such pollutants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title="bioremediation">bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=fungi" title=" fungi"> fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrethroids" title=" pyrethroids"> pyrethroids</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a> </p> <a href="https://publications.waset.org/abstracts/105524/combined-use-of-microbial-consortia-for-the-enhanced-degradation-of-type-iix-pyrethroids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105524.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">147</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">911</span> The Application of Simulation Techniques to Enhance Nitroglycerin Production Efficiency: A Case Study of the Military Explosive Factory in Nakhon Sawan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeerasak%20Wisatphan">Jeerasak Wisatphan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nara%20Samattapapong"> Nara Samattapapong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study's goals were to enhance nitroglycerin manufacturing efficiency through simulation, recover nitroglycerin from the storage facility, and enhance nitroglycerine recovery and purge systems.

The results demonstrate that the alternative system-led Nitroglycerine Recovery and Nitroglycerine Purge System collaborate to produce Nitroglycerine, which is more efficient than other alternatives and can reduce production time. It can also improve the recovery of nitroglycerin. It also serves as a guideline for developing a real-world system and modeling it for training staff without wasting raw chemical materials or fuel energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency%20increase" title="efficiency increase">efficiency increase</a>, <a href="https://publications.waset.org/abstracts/search?q=nitroglycerine%20recovery%20and%20purge%20system" title=" nitroglycerine recovery and purge system"> nitroglycerine recovery and purge system</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20improvement" title=" production improvement"> production improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/161091/the-application-of-simulation-techniques-to-enhance-nitroglycerin-production-efficiency-a-case-study-of-the-military-explosive-factory-in-nakhon-sawan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161091.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">129</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">910</span> Sexual Harassment at University: Male Students' Perspectives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shakila%20Singh">Shakila Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sexual harassment continues to be a problem both in educational institutions and workplaces with the main victims being women and the main perpetrators being men. The achievement of quality education demands to create safe learning spaces for all students and requires extensive and integrated interventions. This article draws on the data from a broader study that aims to create safer learning environments at university by addressing gender violence. It attempts to understand male students’ perspectives about their role in sexual harassment on the campus. It is a move away from interventions that place the responsibility of prevention of sexual harassment, on women. The study adopts an interpretive paradigm within a qualitative approach. The sample comprises twenty male university students who were purposively selected because they live in the campus residences. The main data generation methods included focus group discussions and individual interviews. Findings show that while many male students agree that victims of sexual harassment are mainly women, they also suggest that men are victims of sexual harassment by women. Male students have varying understandings of what constitutes sexual harassment. They position themselves as victims who feel harassed by women’s dress and behaviour. Male students also felt under pressure by sexual advances made by women that forced them to comply in order to protect their masculinity. This article argues that social norms of masculinity are powerful drivers of behaviour that play a key role in the perpetuation of sexual harassment. Male students who feel strongly against sexual harassment of female students are constrained by their masculinities in their ability to act against it. Effective interventions need to actively engage students in reflecting on and challenging social and cultural norms that contribute to violent expressions and to develop alternatives with them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20violence" title="gender violence">gender violence</a>, <a href="https://publications.waset.org/abstracts/search?q=male%20students" title=" male students"> male students</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20harassment" title=" sexual harassment"> sexual harassment</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20students" title=" university students"> university students</a> </p> <a href="https://publications.waset.org/abstracts/85800/sexual-harassment-at-university-male-students-perspectives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85800.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">909</span> Algae Biomass as Alternatives to Wood Pulp in Handmade Paper Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piyali%20Mukherjee">Piyali Mukherjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jai%20Prakash%20Keshri"> Jai Prakash Keshri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anticipated shortages of raw materials for paper industry have forged the entry of algae as alternatives to wood pulp.

Intelligent road design methods that can result in optimized alignment constitute concrete and innovative responses towards better alternatives and more sustainable road infrastructures. As the largest amount of emissions of road infrastructures occur in the operation stage, it becomes very important to consider traffic weight and distribution in alignment design process. This study analyzes the effects of four traffic factors (i.e. operating speed, vehicle category, technology and fuel type) on adjusting the vertical alignment of a given road, using optimization techniques.

The pipeline consists of UNet-based segmentation, lung extraction, and a classification part, with the addition of optional slice removal techniques following the segmentation part. In this work, a batch normalization was added to the original UNet model to produce lighter and better localization, which is then utilized to build a full pipeline for COVID-19 diagnosis. To evaluate the effectiveness of the proposed pipeline, various segmentation methods were compared in terms of their performance and complexity. The proposed segmentation method with batch normalization outperformed traditional methods and other alternatives, resulting in a higher dice score on a publicly available dataset. Moreover, at the slice level, the proposed pipeline demonstrated high validation accuracy, indicating the efficiency of predicting 2D slices. At the patient level, the full approach exhibited higher validation accuracy and macro F1 score compared to other alternatives, surpassing the baseline. The classification component of the proposed pipeline utilizes a convolutional neural network (CNN) to make final diagnosis decisions. The COV19-CT-DB dataset, which contains a large number of CT scans with various types of slices and rigorously annotated for COVID-19 detection, was utilized for classification.

One of the vital and significant examples of the natural challenges is lack or water and desertification. In this research, the project team focuses on redesigning a prototype, using Value Engineering Methodology, which would provide similar functionalities to the well-known technology of Waterboxx kits while reducing the capital and operational costs and simplifying the process of manufacturing and usability by regular farmers. The design employs used tires and recycled plastic sheets as raw materials. Hence, this approach is going to help not just fighting desertification but also helping in getting rid of ever growing huge tire dumpsters in Kuwait, as well as helping in avoiding hazards of tire fires yielding in a safer and friendlier environment. Several alternatives for implementing the prototype have been considered. The best alternative in terms of value has been selected after thorough Function Analysis System Technique (FAST) exercise has been developed. A prototype has been fabricated and tested in a controlled simulated lab environment that is being followed by real environment field testing. Water and soil analysis conducted on the site of the experiment to cross compare between the composition of the soil before and after the experiment to insure that the prototype being tested is actually going to be environment safe. Experimentation shows that the design was equally as effective as, and may exceed, the original design with significant savings in cost. An estimated total cost reduction using the VE approach of 43.84% over the original design. This cost reduction does not consider the intangible costs of environmental issue of waste recycling which many further intensify the total savings of using the alternative VE design. This case study shows that Value Engineering Methodology can be an important tool in innovating new designs for reducing costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desertification" title="desertification">desertification</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20analysis" title=" functional analysis"> functional analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=scrap%20tires" title=" scrap tires"> scrap tires</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20engineering" title=" value engineering"> value engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20recycling" title=" waste recycling"> waste recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20irrigation%20rationing" title=" water irrigation rationing"> water irrigation rationing</a> </p> <a href="https://publications.waset.org/abstracts/76420/design-transformation-to-reduce-cost-in-irrigation-using-value-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76420.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">200</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">905</span> The Morphing Avatar of Startup Sales - Destination Virtual Reality </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sruthi%20Kannan">Sruthi Kannan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ongoing covid pandemic has accelerated digital transformation like never before.

While basic collaborative activities like voice, video calling, screen sharing have been replicated in these alternatives, there are several others that require a more intimate setup. Pitching, showcasing, and providing demonstrations are an integral part of selling strategies for startups. Traditionally these have been in-person engagements, enabling a depth of understanding of the startups’ offerings. In the new normal scenario of virtual-only connects, startups are feeling the brunt of the lack of in-person connections with potential customers and investors. This poster demonstrates how a virtual reality platform has been conceptualized and custom-built for startups to engage with their stakeholders and redefine their selling strategies.

The relationship between these two components, especially in areas surrounding our individual private dwellings, is highly influential on many social, economic, and wellbeing activities that may benefit neighbourhood residents. Neighbourhood and urban design – which are liable to be affected by the perceived quality of local public spaces – are likely to be significant factors influencing broader residents’ feelings of safety. With this in mind, this study reviews recent normative literature on how these design processes have influenced neighbourhood satisfaction including perceived safety with a focus on different aspects of public spaces including planning, management, and design in a mix-tenure neighbourhood. Following the study aim, Riverwood in Sydney’s southwest was chosen as a case study to gain a detailed understanding of the context by engaging with community members, residents, non-government organisations, and experts. Moreover, archival studies on neighbourhood satisfaction and safety, expert interviews, and resident questionnaires are presented to shed light on the relationship between neighbourhood satisfaction and perception of safety. The study argues that for the safer neighbourhood in urban areas, social-cultural factors need to be aligned toward strengthening physical factors and since making the environments safer, it is important to understand practical and achievable mechanisms which are required to improve existing estates. Findings show that increasing the clarity of community social and physical environmental involvements can promote residents’ feelings of safety and following neighbourhood satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neighbourhood%20satisfaction" title="neighbourhood satisfaction">neighbourhood satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20space" title=" public space"> public space</a>, <a href="https://publications.waset.org/abstracts/search?q=Riverwood" title=" Riverwood"> Riverwood</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20safety" title=" urban safety"> urban safety</a> </p> <a href="https://publications.waset.org/abstracts/110209/evaluating-the-relationship-between-neighbourhood-satisfaction-and-urban-safety-the-case-study-of-riverwood-sydney" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110209.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">181</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">903</span> Minimalism in Product Packaging: Alternatives to Bubble Wrap</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anusha%20Chanda">Anusha Chanda</a>, <a href="https://publications.waset.org/abstracts/search?q=Reenu%20Singh"> Reenu Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Packaging is one of the major contributors to global waste. While efforts are being made to switch to more sustainable types of packaging, such as switching from single use plastics to paper, not all polluting materials, have been rethought in terms of recycling. Minimalism in packaging design can help reduce the amount of waste produced greatly. While online companies have shifted to using cardboard boxes for packages, a large amount of waste in still generated from other materials affiliated with cardboard packaging, such as tape, bubble wrap, plastic wrap, among others. Minimalism also works by reducing extra packaging and increasing the reusability of the material. This paper looks at research related to minimalism in packaging design, minimalism, and sustainability. A survey was conducted in order to find out the different ways in which minimalism can be implemented in packaging design. Information gathered from the research and responses from the survey was used to ideate product design alternatives for sustainable substitutes for bubble wrap in packaging. This would help greatly reduce the amount of packaging waste and improve environmental quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=minimalism" title=" minimalism"> minimalism</a>, <a href="https://publications.waset.org/abstracts/search?q=packaging" title=" packaging"> packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20design" title=" product design"> product design</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a> </p> <a href="https://publications.waset.org/abstracts/137772/minimalism-in-product-packaging-alternatives-to-bubble-wrap" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137772.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">902</span> Identification of the Antimicrobial Effect of Liquorice Extracts on Gram-Positive Bacteria: Determination of Minimum Inhibitory Concentration and Mechanism of Action Using a luxABCDE Reporter Strain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madiha%20El%20Awamie">Madiha El Awamie</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Rees"> Catherine Rees</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural preservatives have been used as alternatives to traditional chemical preservatives; however, a limited number have been commercially developed and many remain to be investigated as sources of safer and effective antimicrobials. In this study, we have been investigating the antimicrobial activity of an extract of <em>Glycyrrhiza glabra</em> (liquorice) that was provided as a waste material from the production of liquorice flavourings for the food industry, and to investigate if this retained the expected antimicrobial activity so it could be used as a natural preservative. Antibacterial activity of liquorice extract was screened for evidence of growth inhibition against eight species of Gram-negative and Gram-positive bacteria, including <em>Listeria monocytogenes, Listeria innocua, Staphylococcus aureus, Enterococcus faecalis</em> and <em>Bacillus subtilis</em>. The Gram-negative bacteria tested include <em>Pseudomonas aeruginosa, Escherichia coli </em>and<em> Salmonella typhimurium</em> but none of these were affected by the extract. In contrast, for all of the Gram-positive bacteria tested, growth was inhibited as monitored using optical density. However parallel studies using viable count indicated that the cells were not killed meaning that the extract was bacteriostatic rather than bacteriocidal. The Minimum Inhibitory Concentration [MIC] and Minimum Bactericidal Concentration [MBC] of the extract was also determined and a concentration of 50 µg ml<sup>-1</sup> was found to have a strong bacteriostatic effect on Gram-positive bacteria. Microscopic analysis indicated that there were changes in cell shape suggesting the cell wall was affected. In addition, the use of a reporter strain of <em>Listeria</em> transformed with the bioluminescence genes <em>luxABCDE</em> indicated that cell energy levels were reduced when treated with either 12.5 or 50 µg ml<sup>-1</sup> of the extract, with the reduction in light output being proportional to the concentration of the extract used. Together these results suggest that the extract is inhibiting the growth of Gram-positive bacteria only by damaging the cell wall and/or membrane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title="antibacterial activity">antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=bioluminescence" title=" bioluminescence"> bioluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=Glycyrrhiza%20glabra" title=" Glycyrrhiza glabra"> Glycyrrhiza glabra</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20preservative" title=" natural preservative"> natural preservative</a> </p> <a href="https://publications.waset.org/abstracts/48797/identification-of-the-antimicrobial-effect-of-liquorice-extracts-on-gram-positive-bacteria-determination-of-minimum-inhibitory-concentration-and-mechanism-of-action-using-a-luxabcde-reporter-strain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48797.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">340</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">901</span> Triangular Hesitant Fuzzy TOPSIS Approach in Investment Projects Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irina%20Khutsishvili">Irina Khutsishvili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presented study develops a decision support methodology for multi-criteria group decision-making problem. The proposed methodology is based on the TOPSIS (Technique for Order Performance by Similarity to Ideal Solution) approach in the hesitant fuzzy environment. The main idea of decision-making problem is a selection of one best alternative or several ranking alternatives among a set of feasible alternatives. Typically, the process of decision-making is based on an evaluation of certain criteria. In many MCDM problems (such as medical diagnosis, project management, business and financial management, etc.), the process of decision-making involves experts' assessments. These assessments frequently are expressed in fuzzy numbers, confidence intervals, intuitionistic fuzzy values, hesitant fuzzy elements and so on. However, a more realistic approach is using linguistic expert assessments (linguistic variables). In the proposed methodology both the values and weights of the criteria take the form of linguistic variables, given by all decision makers. Then, these assessments are expressed in triangular fuzzy numbers. Consequently, proposed approach is based on triangular hesitant fuzzy TOPSIS decision-making model. Following the TOPSIS algorithm, first, the fuzzy positive ideal solution (FPIS) and the fuzzy negative-ideal solution (FNIS) are defined. Then the ranking of alternatives is performed in accordance with the proximity of their distances to the both FPIS and FNIS. Based on proposed approach the software package has been developed, which was used to rank investment projects in the real investment decision-making problem. The application and testing of the software were carried out based on the data provided by the ‘Bank of Georgia’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20TOPSIS%20approach" title="fuzzy TOPSIS approach">fuzzy TOPSIS approach</a>, <a href="https://publications.waset.org/abstracts/search?q=investment%20project" title=" investment project"> investment project</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20variable" title=" linguistic variable"> linguistic variable</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-criteria%20decision%20making" title=" multi-criteria decision making"> multi-criteria decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=triangular%20hesitant%20fuzzy%20set" title=" triangular hesitant fuzzy set"> triangular hesitant fuzzy set</a> </p> <a href="https://publications.waset.org/abstracts/59560/triangular-hesitant-fuzzy-topsis-approach-in-investment-projects-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59560.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">428</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">900</span> Re-Analyzing Energy-Conscious Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Svetlana%20Pushkar">Svetlana Pushkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleg%20Verbitsky"> Oleg Verbitsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An energy-conscious design for a classroom in a hot-humid climate is reanalyzed. The hypothesis of this study is that use of photovoltaic (PV) electricity generation in building operation energy consumption will lead to re-analysis of the energy-conscious design. Therefore, the objective of this study is to reanalyze the energy-conscious design by evaluating the environmental impact of operational energy with PV electrical generation. Using the hierarchical design structure of Eco-indicator 99, the alternatives for energy-conscious variables are statistically evaluated by applying a two-stage nested (hierarchical) ANOVA. The recommendations for the preferred solutions for application of glazing types, wall insulation, roof insulation, window size, roof mass, and window shading design alternatives were changed (for example, glazing type recommendations were changed from low-emissivity glazing, green, and double- glazed windows to low-emissivity glazing only), whereas the applications for the lighting control system and infiltration are not changed. Such analysis of operational energy can be defined as environment-conscious analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANOVA" title="ANOVA">ANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=Eco-Indicator%2099" title=" Eco-Indicator 99"> Eco-Indicator 99</a>, <a href="https://publications.waset.org/abstracts/search?q=energy-conscious%20design" title=" energy-conscious design"> energy-conscious design</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%E2%80%93humid%20climate" title=" hot–humid climate"> hot–humid climate</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a> </p> <a href="https://publications.waset.org/abstracts/79830/re-analyzing-energy-conscious-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79830.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">187</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">899</span> Building Safer Communities through Institutional Collaboration in Ghana: An Appraisal of Existing Arrangement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Louis%20Kusi%20Frimpong">Louis Kusi Frimpong</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Oteng-Ababio"> Martin Oteng-Ababio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of crime and insecurity in urban environments are often complex, multilayered, multidimensional and sometimes interwoven. It is from this perspective that recent approaches and strategies aimed at responding to crime and insecurity have looked at the problem from a social, economic, spatial and institutional point of view. In Ghana, there is much understanding of how various elements of the social and spatial setting influence crime and safety concerns of residents in urban areas. However, little research attention has been given to the institutional dimension of the problem of crime and insecurity in urban Ghana. In particular, scholars and policymakers in the area of safety and security have scarcely interrogated the forms of collaboration that exist between the various formal and informal institutions and how gaps and lapses in this collaboration influence vulnerability to crime and feelings of insecurity. Using Sekondi-Takoradi as a case study and drawing on both primary and secondary data, this paper assesses the activities of various institutions both formal and informal in crime control and prevention in the Sekondi-Takoradi metropolis, the third largest city in Ghana. More importantly, the paper seeks to address gaps in the institutional arrangement and coordination between and among institutions at the forefront of crime prevention efforts in the metropolis and by extension Ghanaian cities. The study found that whiles there is some form of collaboration between the police and the community, little collaboration existed between planning authorities and the police on the one hand, and the community on the other hand. The paper concludes that in light of the complex nature of a crime, institutional coordination and an inclusive approach involving formal and informal will be critical in promoting safer cities in Ghana. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crime%20prevention" title="crime prevention">crime prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=coordination" title=" coordination"> coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20arrangement" title=" institutional arrangement"> institutional arrangement</a> </p> <a href="https://publications.waset.org/abstracts/103461/building-safer-communities-through-institutional-collaboration-in-ghana-an-appraisal-of-existing-arrangement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103461.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">126</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">898</span> Methodology of Construction Equipment Optimization for Earthwork </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaehyun%20Choi">Jaehyun Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyunjung%20Kim"> Hyunjung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Namho%20Kim"> Namho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Earthwork is one of the critical civil construction operations that require large-quantities of resources due to its intensive dependency upon construction equipment. Therefore, efficient construction equipment management can highly contribute to productivity improvements and cost savings. Earthwork operation utilizes various combinations of construction equipment in order to meet project requirements such as time and cost. Identification of site condition and construction methods should be performed in advance in order to develop a proper execution plan. The factors to be considered include capacity of equipment assigned, the method of construction, the size of the site, and the surrounding condition. In addition, optimal combination of various construction equipment should be selected. However, in real world practice, equipment utilization plan is performed based on experience and intuition of management. The researchers evaluated the efficiency of various alternatives of construction equipment combinations by utilizing the process simulation model, validated the model from a case study project, and presented a methodology to find optimized plan among alternatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthwork%20operation"
