This study aimed to gain a thorough, in-depth understanding of the opinions of Filipinos from different age and income brackets on these issues in order to address the lack of studies analysing the current Philippine political landscape. An interview tackling relevant national issues were conducted with twelve respondents from the intersections of four age groups and three income brackets. The government’s handling of some issues received mixed opinions, some had neutral viewpoints, while others had more unfavorable ones. The responses differed on three levels: (1) the general stance on an issue; (2) the strength of a stance; and (3) the factoring in of an issue in forming an overall perception on the administration’s performance. Contrary to previous studies on political thought, opinions varied greatly such that no unique set of viewpoints could be attributed to any of the defined age or income groups. These results will be most useful to political science researchers, political analysts, and candidates shaping their platforms for the upcoming elections. Future studies are recommended to tackle more national issues and to consider other factors that may affect political opinions and behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age%20groups" title="age groups">age groups</a>, <a href="https://publications.waset.org/abstracts/search?q=opinion%20formation" title=" opinion formation"> opinion formation</a>, <a href="https://publications.waset.org/abstracts/search?q=socioeconomic%20brackets" title=" socioeconomic brackets"> socioeconomic brackets</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippine%20politics" title=" Philippine politics"> Philippine politics</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Duterte" title=" Rodrigo Duterte"> Rodrigo Duterte</a> </p> <a href="https://publications.waset.org/abstracts/111060/opinions-of-individuals-from-different-age-and-income-brackets-on-the-duterte-administrations-overall-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111060.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">137</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">108</span> Mathematics Vision of the Companies' Growth with Educational Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valencia%20P.%20L.%20Rodrigo">Valencia P.

With 180-degree (180°) acquisition, reconstructed images are distorted in the posterior wall of myocardium due to the lack of sufficient data of posterior projection. We hypothesized that quality of myocardial SPECT images can be improved by the addition of data acquisition of only a few posterior projections to ordinary 180° acquisition. The proposed acquisition method (180° plus acquisition methods) uses the dual-detector SPECT system with a pair of detector arranged in 90° perpendicular. Sampling angle was 5°, and the acquisition range was 180° from 45° right anterior oblique to 45° left posterior oblique. After the acquisition of 180°, the detector moved to additional acquisition position of reverse side once for 2 projections, twice for 4 projections, or 3 times for 6 projections. Since these acquisition methods cannot be done in the present system, actual data acquisition was done by 360° with a sampling angle of 5°, and projection data corresponding to above acquisition position were extracted for reconstruction. We underwent the phantom studies and a clinical study. SPECT images were compared by profile curve analysis and also quantitatively by contrast ratio. The distortion was improved by 180° plus method. Profile curve analysis showed increased of cardiac cavity. Analysis with contrast ratio revealed that SPECT images of the phantoms and the clinical study were improved from 180° acquisition by the present methods. The difference in the contrast was not clearly recognized between 180° plus 2 projections, 180° plus 4 projections, and 180° plus 6 projections. 180° plus 2 projections method may be feasible for myocardial SPECT because distortion of the image and the contrast were improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=180%C2%B0%20plus%20acquisition%20method" title="180° plus acquisition method">180° plus acquisition method</a>, <a href="https://publications.waset.org/abstracts/search?q=a%20few%20posterior%20projections" title=" a few posterior projections"> a few posterior projections</a>, <a href="https://publications.waset.org/abstracts/search?q=dual-detector%20SPECT%20system" title=" dual-detector SPECT system"> dual-detector SPECT system</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20SPECT" title=" myocardial SPECT"> myocardial SPECT</a> </p> <a href="https://publications.waset.org/abstracts/32339/study-of-a-few-additional-posterior-projection-data-to-180-acquisition-for-myocardial-spect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32339.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">295</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">104</span> Virtual Reality Application for Neurorehabilitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Vargas-Herrera">Daniel Vargas-Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivette%20Caldelas"> Ivette Caldelas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Brambila-Paz"> Fernando Brambila-Paz</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Montufar-Chaveznava"> Rodrigo Montufar-Chaveznava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a virtual reality application for neurorehabilitation.

The sample is comprised of 346 companies from 10 international markets, of which 49 companies (and a subsample of 13 distressed companies) lose a combined US$18.9 billion. An event study shows that most companies that present losses in derivatives experience negative abnormal returns, including a number of companies in which the effect is persistent after a year. The results of a probit model indicate that the lack of a formal hedging policy, no monitoring to the CFOs, and considerations of hubris and remuneration contribute to the mismanagement of hedging policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title="risk management">risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=hedging" title=" hedging"> hedging</a>, <a href="https://publications.waset.org/abstracts/search?q=derivatives" title=" derivatives"> derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance%20structure" title=" corporate governance structure"> corporate governance structure</a>, <a href="https://publications.waset.org/abstracts/search?q=event%20study" title=" event study"> event study</a>, <a href="https://publications.waset.org/abstracts/search?q=hubris" title=" hubris"> hubris</a> </p> <a href="https://publications.waset.org/abstracts/3438/hedging-and-corporate-governance-lessons-from-the-financial-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3438.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">442</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">102</span> Quality Control of 99mTc-Labeled Radiopharmaceuticals Using the Chromatography Strips</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasuyuki%20Takahashi">Yasuyuki Takahashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Akemi%20Yoshida"> Akemi Yoshida</a>, <a href="https://publications.waset.org/abstracts/search?q=Hirotaka%20Shimada"> Hirotaka Shimada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 99mTc-2-methoxy-isobutyl-isonitrile (MIBI) and 99mTcmercaptoacetylgylcylglycyl-glycine (MAG3 ) are heat to 368-372K and are labeled with 99mTc-pertechnetate. Quality control (QC) of 99mTc-labeled radiopharmaceuticals is performed at hospitals, using liquid chromatography, which is difficult to perform in general hospitals. We used chromatography strips to simplify QC and investigated the effects of the test procedures on quality control. In this study is 99mTc- MAG3. Solvent using chloroform + acetone + tetrahydrofuran, and the gamma counter was ARC-380CL. The changed conditions are as follows; heating temperature, resting time after labeled, and expiration year for use: which were 293, 313, 333, 353 and 372K; 15 min (293K and 372K) and 1 hour (293K); and 2011, 2012, 2013, 2014 and 2015 respectively were tested. Measurement time using the gamma counter was one minute. A nuclear medical clinician decided the quality of the preparation in judging the usability of the retest agent. Two people conducted the test procedure twice, in order to compare reproducibility. The percentage of radiochemical purity (% RCP) was approximately 50% under insufficient heat treatment, which improved as the temperature and heating time increased. Moreover, the % RCP improved with time even under low temperatures. Furthermore, there was no deterioration with time after the expiration date. The objective of these tests was to determine soluble 99mTc impurities, including 99mTc-pertechnetate and the hydrolyzed-reduced 99mTc.

It is concluded that quality control is a necessary procedure in nuclear medicine to ensure safe scanning.

Maintenance of mitochondrial efficiency is required to supply the ATP necessary for granulosa cell proliferation during the follicular development process. Treatment with Pyrroloquinoline quinone (PQQ) has been reported to increase the number of ovulated oocytes and pups per delivery in mice by maintaining healthy mitochondrial function. This study aimed to elucidate how PQQ maintains mitochondrial function during ovarian follicle growth. To do this, both in vitro and in vivo experiments were performed with granulosa cells from superovulated immature (3-week-old) mice that were pretreated with or without PQQ. The effects of PQQ on beta-oxidation, mitochondrial function, mitophagy, and mitochondrial biogenesis were examined. PQQ increased beta-oxidation-related genes and CPT1 protein content in granulosa cells and this was associated with a decreased phosphorylation of P38 signaling protein. Using the fatty acid oxidation assay on the flux analyzer, PQQ increased the reliance of beta-oxidation on the endogenous fatty acids and was associated with a mild UCP-dependant mitochondrial uncoupling, ATP production, mitophagy, and mitochondrial biogenesis. PQQ also increased the expression of endogenous antioxidant enzymes. Thus, PQQ induced beta-oxidation in growing granulosa cells relying on endogenous fatty acids. And reduced the Reactive oxygen species (ROS) production by inducing a mild mitochondrial uncoupling with keeping high mitochondrial function. Damaged mitochondria were recycled by the induced mitophagy and replaced by the increased mitochondrial biogenesis. Collectively, PQQ may enhance reproductivity by maintaining the efficiency of mitochondria to produce enough ATP required for normal folliculogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=granulosa%20cells" title="granulosa cells">granulosa cells</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20uncoupling" title=" mitochondrial uncoupling"> mitochondrial uncoupling</a>, <a href="https://publications.waset.org/abstracts/search?q=mitophagy" title=" mitophagy"> mitophagy</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrroloquinoline%20quinone%20%28PQQ%29" title=" pyrroloquinoline quinone (PQQ)"> pyrroloquinoline quinone (PQQ)</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species%20%28ROS%29." title=" reactive oxygen species (ROS)."> reactive oxygen species (ROS).</a> </p> <a href="https://publications.waset.org/abstracts/156680/pyrroloquinoline-quinone-enhances-the-mitochondrial-function-by-increasing-beta-oxidation-and-a-balanced-mitochondrial-recycling-in-mice-granulosa-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156680.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">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">97</span> Analyzing the Evolution and Maturation of Bitcoin Improvement Proposals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Costa">Rodrigo Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Mazzuchi"> Thomas Mazzuchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahram%20Sarkani"> Shahram Sarkani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study analyzes the evolution of Bitcoin Improvement Proposals (BIPs), the self-governing mechanism that enables updates to the Bitcoin protocol. By modeling BIP submission frequencies with a Negative Binomial distribution and detecting change points with the Pelt Rupture model, we identify three distinct intervals of proposal activity, suggesting shifts in development priorities over time. Long-term growth patterns, captured by Gompertz and Weibull models, indicate an S-shaped trend in cumulative BIP counts, pointing toward a maturation phase in Bitcoin’s protocol. Our findings suggest that Bitcoin may be entering a stable stage, with fewer fundamental changes and more incremental enhancements. This trend highlights the need for further research into BIP content and more studies into its dynamics to better understand decentralized protocol governance and maturation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bitcoin%20improvement%20proposals" title="bitcoin improvement proposals">bitcoin improvement proposals</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20management" title=" innovation management"> innovation management</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20point%20detection" title=" change point detection"> change point detection</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20modeling" title=" systems modeling"> systems modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/194645/analyzing-the-evolution-and-maturation-of-bitcoin-improvement-proposals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194645.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">5</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">96</span> Development of Ferrous-Aluminum Alloys from Recyclable Material by High Energy Milling </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arnold%20S.%20Freitas%20Neto">Arnold S.

However, the 180 to 240 minutes (min) waiting time after the intravenous (i.v.) injection of the tracer is both long and tiresome. To solve this shortcoming, a bone scan with a shorter waiting time is needed. In this study, we applied the Maximum Intensity Projection (MIP) and triple energy window (TEW) scatter correction to a whole body bone SPECT (Merged SPECT) and investigated shortening the waiting time. Methods: In a preliminary phantom study, hot gels of 99mTc-HMDP were inserted into sets of rods with diameters ranging from 4 to 19 mm. Each rod set covered a sector of a cylindrical phantom. The activity concentration of all rods was 2.5 times that of the background in the cylindrical body of the phantom. In the human study, SPECT images were obtained from chest to abdomen at 30 to 180 min after 99mTc- hydroxymethylene diphosphonate (HMDP) injection of healthy volunteers. For both studies, MIP images were reconstructed. Planar whole body images of the patients were also obtained. These were acquired at 200 min. The image quality of the SPECT and the planar images was compared. Additionally, 36 patients with breast cancer were scanned in the same way. The delectability of uptake regions (metastases) was compared visually. Results: In the phantom study, a 4 mm size hot gel was difficult to depict on the conventional SPECT, but MIP images could recognize it clearly. For both the healthy volunteers and the clinical patients, the accumulation of 99mTc-HMDP in the SPECT was good as early as 90 min. All findings of both image sets were in agreement. Conclusion: In phantoms, images from MIP with TEW scatter correction could detect all rods down to those with a diameter of 4 mm. In patients, MIP reconstruction with TEW scatter correction could improve the detectability of hot lesions. In addition, the time between injection and imaging could be shortened from that conventionally used for whole body scans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=merged%20SPECT" title="merged SPECT">merged SPECT</a>, <a href="https://publications.waset.org/abstracts/search?q=MIP" title=" MIP"> MIP</a>, <a href="https://publications.waset.org/abstracts/search?q=TEW%20scatter%20correction" title=" TEW scatter correction"> TEW scatter correction</a>, <a href="https://publications.waset.org/abstracts/search?q=99mTc-HMDP" title=" 99mTc-HMDP"> 99mTc-HMDP</a> </p> <a href="https://publications.waset.org/abstracts/13577/preliminary-evaluation-of-maximum-intensity-projection-spect-imaging-for-whole-body-tc-99m-hydroxymethylene-diphosphonate-bone-scanning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13577.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">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">94</span> Nonuniformity Correction Technique in Infrared Video Using Feedback Recursive Least Square Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Flavio%20O.%20Torres">Flavio O.

Located above the equator, it is possible that Japan may benefit from future climate change, yet Japan is also a rarely developed country located in the Asian Monsoon climate region, making it vulnerable to the impacts of climate change. In this regard, the Japanese government has initiated policies to adapt to the adverse effects of climate change through the promotion and popularization of environmentally-friendly farming practices. This study aims to determine profit efficiency among environmentally-friendly rice farmers in Shiga Prefecture using the Stochastic Frontier Approach. A cross-sectional survey was conducted among 66 farmers from top rice-producing cities through a structured questionnaire. Results showed that the gross farm income of environmentally-friendly rice farmers was higher by JPY 316,223.00/ha. Production costs were also found to be higher among environmentally-friendly rice farmers, especially on labor costs, which accounted for 32% of the total rice production cost. The resulting net farm income of environmentally-friendly rice farmers was only higher by JPY 18,044/ha. Results from the stochastic frontier analysis further showed that the profit efficiency of conventional farmers was only 69% as compared to environmentally-friendly rice farmers who had a profit efficiency of 76%. Furthermore, environmentally-friendly agriculture participation, other types of subsidy, educational level, and farm size were significant factors positively influencing profit efficiency.

An environmentally friendly alternative is the use of this waste for the production of cement-wood composites. The aim of this work was to study the possibility of using wood treated with CCA (Chromated Cooper Arsenate) in cement-wood. Specimens of Pinus sp. and Eucalyptus sp. were produced with wood raw in natura and treated with CCA. A test was performed to determine the parallel shear stress of samples after 14 days of drying, according to the Brazilian Standard NBR-7215/97. Based on the analyzed results it is concluded that the use of wood treated with CCA is not feasible in cement-wood production, because the composite samples of treated wood showed lower mechanical strength in shear stress than those with wood in natura. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20recovery" title="waste recovery">waste recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20composites" title=" wood composites"> wood composites</a>, <a href="https://publications.waset.org/abstracts/search?q=cement-wood" title=" cement-wood"> cement-wood</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20preservation" title=" wood preservation"> wood preservation</a>, <a href="https://publications.waset.org/abstracts/search?q=chromated%20copper%20arsenate" title=" chromated copper arsenate"> chromated copper arsenate</a> </p> <a href="https://publications.waset.org/abstracts/13252/study-on-parallel-shear-stress-of-cement-wood-composites-using-pinus-sp-and-eucalyptus-sp-in-natura-and-treated-with-cca" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13252.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">620</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">90</span> Computational Fluids Dynamics Investigation of the Effect of Geometric Parameters on the Ejector Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michel%20Wakim">Michel Wakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Rivera%20Tinoco"> Rodrigo Rivera Tinoco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Supersonic ejector is an economical device that use high pressure vapor to compress a low pressure vapor without any rotating parts or external power sources. Entrainment ratio is a major characteristic of the ejector performance, so the ejector performance is highly dependent on its geometry. The aim of this paper is to design ejector geometry, based on pre-specified operating conditions, and to study the flow behavior inside the ejector by using computational fluid dynamics ‘CFD’ by using ‘ANSYS FLUENT 15.0’ software. In the first section; 1-D mathematical model is carried out to predict the ejector geometry. The second part describes the flow behavior inside the designed model. CFD is the most reliable tool to reveal the mixing process at different parts of the supersonic turbulent flow and to study the effect of the geometry on the effective ejector area.

Located in central Brazil, its preservation is seriously threatened by the advance of intensive agriculture and livestock. Conservation Units and Indigenous Lands are increasingly isolated and subject to mega wildfires. Among the characteristics of this savanna, we highlight the high rate of primary biomass production and the reduced occurrence of large grazing animals. In this biome, the predominant fauna is more dependent on the fruits produced by the dicotyledonous species in relation to other tropical savannas. Fire is a key element in the balance between mono and dicotyledons or between the arboreal and herbaceous strata. Therefore, applying fire regimes that maintain the balance between these strata without harming fruit production is essential in the conservation strategies of Cerrado's biodiversity. Recently, Integrated Fire Management has started to be implemented in Brazilian protected areas. As a result, management with prescribed burns has increasingly replaced strategies based on fire exclusion, which in practice have resulted in large wildfires, with highly negative impacts on fruit and fauna production. In the Indigenous Lands, these fires were carried out respecting traditional knowledge. The indigenous people showed great concern about the effects of fire on fruit plants and important animals. They recommended that the burns be carried out between April and May, as it would result in a greater production of edible fruits ("fruiting burning"). In other tropical savannas in the southern hemisphere, the preferential period tends to be later, in the middle of the dry season, when the grasses are dormant (June to August). However, in the Cerrado, this late period coincides with the flowering and sprouting of several important fruit species. To verify the best burning season, the present work evaluated the effects of fire on flowering and fruit production of theByrsonima sp., Mouriri pusa, Caryocar brasiliense, Anacardium occidentale, Pouteria ramiflora, Hancornia speciosa, Byrsonima verbascifolia, Anacardium humille and Talisia subalbens. The evaluations were carried out in the field, covering 31 Indigenous Lands that cover 104,241.18 Km², where 3,386 prescribed burns were carried out between 2015 and 2018. The burning periods were divided into early (carried out during the rainy season), modal or “fruiting” (carried out during the transition between seasons) and late (carried out in the middle of the dry season, when the grasses are dormant). The results corroborate the traditional knowledge, demonstrating that the modal burns result in higher rates of reproduction and fruit production. Late burns showed intermediate results, followed by early burns. We conclude that management strategies based mainly on forage production, which are usually applied in savannas populated by grazing ungulates, may not be the best management strategy for South American savannas. The effects of fire on fruit plants, which have a particular phenologicalsynchronization with the fauna cycle, also need to be observed during the prescription of burns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cerrado%20biome" title="cerrado biome">cerrado biome</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20regimes" title=" fire regimes"> fire regimes</a>, <a href="https://publications.waset.org/abstracts/search?q=native%20fruits" title=" native fruits"> native fruits</a>, <a href="https://publications.waset.org/abstracts/search?q=prescribed%20burns" title=" prescribed burns"> prescribed burns</a> </p> <a href="https://publications.waset.org/abstracts/136541/the-importance-of-fruit-trees-for-prescribed-burning-in-a-south-american-savanna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136541.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">217</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">84</span> Performance Evaluation of a Minimum Mean Square Error-Based Physical Sidelink Share Channel Receiver under Fading Channel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yang%20Fu">Yang Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Rodrigo%20Navarro"> Jaime Rodrigo Navarro</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20F.%20Monserrat"> Jose F.

From Release 16 to Release 17, the Third Generation Partnership Project (3GPP) has introduced the definitions and services for 5G New Radio (NR) V2X. Experience from previous generations has shown that establishing a simulator for C-V2X communications is an essential preliminary step to achieve reliable and stable communication links. This paper proposes a complete framework of a link-level simulator based on the 3GPP specifications for the Physical Sidelink Share Channel (PSSCH) of the 5G NR Physical Layer (PHY). In this framework, several algorithms in the receiver part, i.e., sliding window in channel estimation and Minimum Mean Square Error (MMSE)-based equalization, are developed. Finally, the performance of the developed PSSCH receiver is validated through extensive simulations under different assumptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C-V2X" title="C-V2X">C-V2X</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20estimation" title=" channel estimation"> channel estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=link-level%20simulator" title=" link-level simulator"> link-level simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=sidelink" title=" sidelink"> sidelink</a>, <a href="https://publications.waset.org/abstracts/search?q=3GPP" title=" 3GPP"> 3GPP</a> </p> <a href="https://publications.waset.org/abstracts/163477/performance-evaluation-of-a-minimum-mean-square-error-based-physical-sidelink-share-channel-receiver-under-fading-channel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163477.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">130</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">83</span> Transaction Cost Analysis, Execution Quality, and Best Execution under MiFID II</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Zepeda">Rodrigo Zepeda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transaction cost analysis (TCA) is a way of analyzing the relative performance of different intermediaries and different trading strategies for trades undertaken in financial instruments. It is a way for an investor to determine the overall quality of execution of a particular trade, and there are many different approaches to undertaking TCA. Under the updated Markets in Financial Instruments Directive (2014/65/EU) (MiFID II), investment firms are required when executing orders, to take all sufficient steps to obtain the best possible result for their clients. This requirement for 'Best Execution' must take into account price, costs, speed, likelihood of execution and settlement, size, nature or any other consideration relevant to the execution of the order. The new regulatory compliance framework under MiFID II will now also apply across a very broad range of financial instruments. This article will provide a comprehensive technical analysis of how TCA and Best Execution will significantly change under MiFID II. It will also explain why harmonization of post-trade reporting requirements under MiFID II could potentially support the development of peer group analysis, which in turn could provide a new and highly advanced framework for TCA that could more effectively support Best Execution requirements under MiFID II. The study is significant because there are no studies that have dealt with TCA and Best Execution under MiFID II in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transaction%20cost%20analysis" title="transaction cost analysis">transaction cost analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=execution%20quality" title=" execution quality"> execution quality</a>, <a href="https://publications.waset.org/abstracts/search?q=best%20execution" title=" best execution"> best execution</a>, <a href="https://publications.waset.org/abstracts/search?q=MiFID%20II" title=" MiFID II"> MiFID II</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20instruments" title=" financial instruments"> financial instruments</a> </p> <a href="https://publications.waset.org/abstracts/69323/transaction-cost-analysis-execution-quality-and-best-execution-under-mifid-ii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69323.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">290</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">82</span> Digital Maturity Framework: A Tool to Manage the Information Technologies and Develop Activities of Innovation in Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulina%20Sol%C3%B3rzano%20Salgado">Paulina Solórzano Salgado</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Rodrigo%20Valencia%20P%C3%A9rez"> Luis Rodrigo Valencia Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20de%20Jes%C3%BAs%20Pastrana%20Palma"> Alberto de Jesús Pastrana Palma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, it is presented a digital maturity framework, which contributes to the development of small and medium-sized enterprises (SMEs) in the commercial sector. This proposal is based on three important concepts: Marketing activities in the enterprise, information and communication technologies ICT, as well as Innovation. Prior to the development of this framework, was formulated a quantitative assessment tool through a literature review, and was validated with a method used by experts, and which determines the relationship of digital marketing and innovation activities in companies. The instrument was applied to 64 Mexican companies from the Made in Mexico database, which allowed both descriptive results and correlation results. These contributed to the development of the methodology, and confirming that the management of digital marketing has a positive relation with innovation activities of companies. Also, that analytics in digital marketing is a source for its development. In this paper, the management stages and activities are presented to be developed by companies in order to generate knowledge, which will allow them to reach its digital maturity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20marketing" title="digital marketing">digital marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20maturity" title=" digital maturity"> digital maturity</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a> </p> <a href="https://publications.waset.org/abstracts/70476/digital-maturity-framework-a-tool-to-manage-the-information-technologies-and-develop-activities-of-innovation-in-companies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70476.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">469</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">81</span> Proposals for Continuous Quality Improvement of Public Transportation Federal District Using SERVQUAL</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Guimar%C3%A3es%20Santos">Rodrigo Guimarães Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of public transport services has been considered as a critical factor by their users and also by users of individual transport. Thus, this dissertation aims to adapt a model that assesses the quality of public transport and determines its level of service based on the views of its users. The methodology is widely used by marketers and allows measuring the quality of services by assessing the perceptions and expectations of users. The adapted SERVQUAL was tested with users of public transport service users and car in Brasília-DF, city of Brazil. This research involved 241 questionnaires answered by people living in the various administrative regions of Brasília-DF. The analysis of the determinants pointed out that the quality of the public transport service offered in the city is low and users of public transport and cars have a high degree of expectations for improvement in all tested determinants. This method enabled the identification of the most critical determinants and those needing strategic actions for continuous improvement of quality. Adapting the SERVQUAL for a public transport service was satisfactory and demonstrated applicability to internal and external services, including measuring the public transport services in other cities with the opinion of the users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transportation%20services" title="transportation
