Wireless sensor networks (WSN) have been implemented in nearly every field of use because they offer a solution to practical problems that can also be affordably implemented. The sensor nodes have limited computing resources, weak batteries, and limited storage space. The environmental or physical data collected by these nodes is transmitted straight to the BS. The data transfer cost is raised due to the direct data transmission. In addition, the lifetime of sensor networks is shortened because of the rise in energy required for data exchange. As a result, data aggregation is utilized in WSN to lessen the burden of transmission costs and lengthen the useful life of the sensor networks. Each sensor node's transmission is encrypted with cipher text generated by the Paillier homomorphic cryptosystem. In addition, the Bilinear aggregate signature method is used to create a digital signature at each sensor node. The cluster head BS is where the aggregation takes place once the cipher text and signature have been combined. Before deciding whether to accept or reject the message, the BS checks the aggregate signature. The homomorphic cryptosystem saves power because it does not perform intermediate-level or cluster-head decryption. Data integrity, authenticity, and confidentiality are all maintained while using less power with this technology. The Intel laboratory dataset is used in the implementation. When compared to current systems, the proposed SDA method requires less time and energy to calculate.

Authors: Antonio Vida V , Diculen Ligaya B
Published: May 2023

The use of indigenous game-based activities in teaching Physics concepts can eradicate the continuous perception of students that Physics is a boring and difficult subject. This study focused on the development and validation of indigenous game-based activities (IGBA) that can be used as a springboard to teach Physics concepts and enhance the performance of students. It used the Research and Development methodology that includes the validation of the indigenous game-based activities and try-out wherein the researcher used one-group pretest-posttest design to 42 purposively-selected students in a public secondary school in eastern Ilocos Norte, Philippines. Using a researcher-made and item-analyzed pretest and posttest, an adapted students’ views checklist, interview guide and adapted validation tool, the study found out that Ilocos Norte has a lot of indigenous games rich with Physics concepts, using games familiar to students encourages better participation among learners and solicits greater interest towards the subject, thus making the teaching-learning process more appealing to students. The purposively selected teachers strongly agreed that the IGBA is a valid instructional material for teaching Physics concepts. Tryout results show that the material effectively improves students’ performance in Physics.  It was supported by students’ views that when the activities are used in teaching, Physics becomes interesting, motivating, challenging, enjoyable and full of fun, not difficult to learn and understand because they are applicable and relevant, not time consuming because they ease students’ burden in problem-solving, elicit maximum participation among learners, and ensure greater retention of the concepts they learn.

Published: May 2023

Antimicrobial resistance (AMR) is a growing public health concern globally, with the threat of a post-antibiotic era, where common infections can become fatal, a very plausible reality. Despite ongoing efforts to control AMR, both mortality and expenses have increased. To combat this threat, a thorough understanding of the mechanisms and the driver behind this issue needs to be known. The key mechanisms of resistance are modification or destruction of antimicrobials, reduction of access to the target, and alteration of the target. These mechanisms may be present in the microorganisms naturally or may have been acquired from other microorganisms. As AMR jeopardizes the successful prevention and treatment of many infectious diseases, this article looks at the causes of AMR, along with the possible mechanisms of resistance development, and suggested control strategies to deal with the problem conclusively.

Authors: Mishra Shree , Sahu Binod , Kar Sushree , Dixit Sanjukta , Dash Ambika
Published: May 2023

Background: The prostate is a male reproductive accessory gland which gives rise to several pathological conditions. The present study aims to study the correlation of histopathology of prostatic diseases with the clinical profile of the patient coming to VSS Medical College (VSSMC), Burla for histopathological reporting of prostatic biopsies.

Aim and Objectives: The objectives of this study were as follows: (1) To correlate serum prostate-specific antigen (PSA) level with various clinical and pathological lesions of the prostrate gland, in a Hospital-based sample of Western Odisha population. (2) As the male gender represents almost half of the entire population, to find out different clinicopathological lesions, percentage-wise, so as to know the frequency of occurrence of such lesions.

Materials and Methods: Fifty-seven cases of prostatic diseases were recorded in the Department of Pathology, VSSMC, Burla for histopathological examination of prostatic tissue for 2 years from September 2017 to August 2019. All the samples were fixed in 5 μ sections with 10% neutral buffered formalin. Then Hematoxylin and Eosin stain (H and E stain) was used for staining. Appropriate clinical data comprising signs and symptoms, laboratory findings, and serum PSA levels were recorded.

Results: The present study, in the beginning, consisted of 64 patients, out of which seven patients were excluded by exclusion criteria, and finally, 57 cases were analyzed. The most prevalent age group for all prostatic diseases was 61–70 years with a mean of 67 years. The majority of the cases (73.67%) were benign mostly benign prostatic hyperplasia (BPH). Prostatic intraepithelial neoplasia (PIN) was 12.29% and malignant cases (all adenocarcinoma) were also 12.29%. All patients showed prostatomegaly. About 50% of cases suggestive of malignancy by digital rectal examination (DRE) were confirmed to be carcinoma by histopathological study. Serum creatinine level was raised in 16.27% of benign and 21.42% of premalignant and malignant conditions. Serum PSA level below 4 ng/mL were all benign and above 10 ng/mL were majority malignant conditions. However, at level 4–10 ng/mL, BPH and PIN cases were overlapped with cases of carcinoma.

Conclusion: Benign prostatic hyperplasia is the most commonly encountered prostatic lesion. Serum PSA level <4 ng/mL is associated with benign conditions and more than 10 ng/mL is associated more with carcinomas. Although, investigations such as DRE and serum PSA estimation aid in diagnosis, a definitive diagnosis of benign and malignant lesions of prostate can be made by histopathological study of prostatic biopsies.

This research article was an exploratory research study entitled, “Perception analysis on passenger’s attitudes toward home baggage check-in: revamping the aviation experience.” It was intended to study the passengers’ attitudes toward the home baggage check-in system and to reinvent the aviation experience. The overall passenger experience at the airport is cumbersome and time-consuming. The passenger not only has to arrive early but also has to go through a lot of security check-in procedures. But with a home baggage check-in system, one can avoid going through all this trouble and it also consumes less time and is very safe. Home baggage check-in is an emerging concept of home or hotel delivery and pickup service. One has to book a luggage pick-up slot online, hand their bags over after passing through Customs, and the bags will be delivered to their home, business or hotel, or the destination airport leaving them hassle-free. With Home check-in, one can avoid the usual check-in queues at the airport and head straight to the gate. While collecting the luggage, the agent will weigh the bags at the passenger’s home before they are checked in, so if they need to pay for extra baggage – or take anything out of their luggage – they can simply arrange it there and then. After checking – in the baggage, the agent will hand over the boarding pass with the instructions. One can even reserve their seat on board to make sure that they sit close to the people they are traveling with. The collected bags will be kept safe and secure before they are loaded on the flight, and the passengers will be kept up-to-date with SMS notifications letting them know exactly where their bags are at every step of their journey. The objective of the research was to compare the typical baggage check-in system and the home baggage check-in system, to analyze the passengers’ attitudes toward the home baggage check-in system, and to revise the aviation experience. In this study, the total sample size consisted of 150 participants. The tools used for data collection were personal data sheets and questionnaires on the passengers’ attitudes toward home baggage check-in. The collected data were classified, tabulated, assessed, and further analyzed. The results showed that almost every participant was extremely satisfied with the idea of introducing home baggage check-in services but was dissatisfied and unwilling to pay the extra amount charged by the airline for availing of the home baggage check-in service.

Authors: Cuisano Julio , Puma Solin
Published: May 2023

The effects of anhydrous ethanol (E) and castor oil (R) mixed with diesel fuel (D), commercially containing 5% biodiesel by volume, were researched experimentally to evaluate the combustion process and specific fuel consumption in a compression ignition engine, supercharged, six cylinders. In total, three mixtures were used, varying the diesel content from 95% (D95) to 80% v/v (D85), obtaining the following compositions: D95B0E0, D85B6E9 and D80B6.5E13.5. The experimental tests were performed in stationary conditions (1000 and 1800 rpm), two values ​​of effective torque (80, and 160N.m) and two conditions of intake air pressure (100 and 80 kPa).  The results obtained show that the mixtures containing ethanol and biodiesel lead to an early start of combustion at 1000 rpm and a delay at the start of combustion at 1800 rpm. The increase in ethanol and biodiesel over commercial fuel does not have any influence on specific fuel consumption; however, the altitude effect generates an increase in specific fuel consumption up to 11% and 7% at 1000 rpm and 1800 rpm respectively. The specific emissions of NOX, CO and CO2are increased with higher specific fuel consumption; in addition, the effect of simulated altitude allowed to verify that at higher altitudes there is a slight increase in sfc and EE of CO and CO2, together with a reduction in EE NOX. At 2000 m of simulated altitude (APCI = 80 kPa) the maximum increases of sfc, CO and CO2, with the mixture D80B6.5E13.5, were 5%, 122% and 18%, respectively. And the maximum reductions in NOX EE were also obtained with the D80B6.5E13.5 mixture, reaching decreases of up to 6%.

Published: May 2023

This paper describes the development of a system for detecting driver drowsiness whose goal is to alert drivers of their sleepy state to prevent traffic accidents. It is essential that drowsiness detection in a driving environment be conducted in a non-intrusive manner and that the driver not be troubled by alerts when they are not sleepy. We make use of the MediaPipe Facemesh framework to extract facial features and the Binary Classification Neural Network to precisely detect drowsy states in our solution to this open problem. The solution that minimize false positives is created to determine whether or not the driver exhibits sleepiness symptoms. The approach extracts numerical features from images using deep learning techniques, which are then added to a fuzzy logic-based system. This system typically achieve 91% accuracy on training data and 92% accuracy on test data. The fuzzy logic-based approach, however, stands out because it doesn't raise erroneous alerts (percentage of correctly identified footage where the driver is not tired). Although the findings are not particularly satisfying, the recommendations offered in this study are promising and may be used as a strong platform for future work.

Authors: Shah Pramatma Ram
Published: May 2023

Bituminous concrete mix is a composite material which is widely used for the construction of flexible pavements, surfacing of roads and airports, various parking lots etc. It generally consists of bitumen which works as a binder material, coarse aggregates, fine aggregates and filler materials which are generally mixed together in right proportion and laid down in layers followed by the compaction. In this present age of modernization and urbanization, construction is non stoppable and the construction by demolishing of old building has arisen a serious problem of treatment of demolished waste. Similarly, the use of plastic in our day-to-day life and its improper disposal is also creating serious environment pollution. So, there is big challenge in managing the demolished waste as well as the waste plastics. In this project i.e. partial replacement of RCA and LDPE in Bituminous concrete mix we have tried to replace the RCA (25%) in Natural Aggregates and LDPE (2%, 4%, 6% and 8% respectively) in bitumen content for the improvement of the pavement characteristics satisfying both the strength criteria and the economic aspects giving emphasize to less environment degradation and sustainability.

O modelo foi desenvolvido e validado pelos gestores locais da unidade e pelos gestores de nível estratégico, na sede, ao longo de um ano de pesquisa, e sua continuidade dar-se-á pelo seu escalonamento (replicabilidade) para as demais unidades da organização. As limitações enfrentadas foram em virtude do momento de mudança de direcionamento pelo qual a unidade passou no ano de execução da pesquisa, até então (2016) as unidades tinham foco em prover formação tecnológica de nível médio alinhada à vocação produtiva do Arranjo Produtivo Local, a partir de então (2017) as unidades passaram a ter foco no provimento de serviços tecnológicos além da formação tecnológica, de modo que a equipe de gestores da unidade (objeto de estudo) começou um processo de adaptação às novas demandas ao mesmo tempo em que a pesquisa era conduzida, fato que retardou em alguns momentos as etapas de coleta de dados e validação do modelo proposto. Os impactos esperados são o compartilhamento das boas práticas e resultados positivos tanto entre as unidades da organização, quanto entre as unidades e outros membros do ecossistema de inovação, a fim de que os processos de gestão da tecnologia e inovação inerentes às organizações componentes do sistema impactem numa melhoria de seus respectivos desempenhos, contribuindo assim para a melhoria do próprio ecossistema como um todo.
Gastos municipais em educação e o provimento de serviços educacionais pelo município: análise empírica sobre a influência de observatórios sociais nessa relação

A educação é um dos principais alvos da corrupção nos municípios brasileiros. Falhas nos mecanismos institucionais de controle da Administração Pública permitem que a corrupção municipal se multiplique, forçando a sociedade civil organizada a se mobilizar. Desde meados dos anos 2000, uma estratégia de monitoramento do setor público pela sociedade civil, que utiliza observatórios sociais para fiscalizar as licitações e condutas das prefeituras e secretarias municipais, foi implantada em centenas de municípios. Apesar disso, há dúvidas sobre a efetividade dessa modalidade de controle social, devido à escassez de estudos sobre seus efeitos, especialmente na educação municipal brasileira, onde não existem pesquisas dessa natureza. A literatura internacional mostra que desvios ilícitos e/ou graves ineficiências na gestão dos recursos da educação pública enfraquecem a relação entre o gasto governamental e o acesso da população aos serviços educacionais; de modo que coeficientes estatisticamente nulos, ou positivos, mas próximos de zero, para esta relação, representam sinais de corrupção ou graves ineficiências. Com base nisso, esta pesquisa avalia a existência de indícios de corrupção/ineficiências na gestão da educação municipal, analisando se a ação dos observatórios sociais é capaz de mitigá-los. A partir de um desenho metodológico que utiliza dados em painel e o método generalizado de momentos para estimar estes coeficientes nos períodos pré e pós-intervenção, comparando-os aos de um grupo de controle selecionado por pareamento por escore de propensão, encontramos evidências que sugerem que os observatórios sociais são efetivos no combate à corrupção, ineficiências administrativas e comportamentos oportunistas na gestão da educação municipal.Parte superior do formulário

The use of soil cover plants and alternative sources of nitrogen fertilization can promote improvements in the biological characteristics of the soil. The objective of this study was to determine the contribution of the isolated and/or intercropped cultivation of ground cover crops in autumn/winter and the use of poultry litter as a source of N in the wheat crop in succession on the soil mesofauna and macrofauna community. The experimental design was randomized blocks, with split plots, in a factorial arrangement (4 x 4), with three replications. The collections of the edaphic fauna were realized with pitfall traps PROVID in plots of 15 m². The edaphic fauna orders, abundance, Shannon diversity, Simpson dominance, Pielou evenness and the family of organisms of the order Collembola were evaluated. The use of ground cover plants in autumn/winter, induced a greater abundance of edaphic fauna organisms, which were mostly represented by the order Collembola, belonging to the Entomobryidae family. The isolated or intercropped cultivation of cover crops, associated with the use of N via poultry litter, enabled a greater diversity of organisms and a uniform distribution of different groups in the edaphic community.

Las pruebas de confianza “POLIGRAFO” son o no legales y que influencia tienen en la desvinculación de servidores policiales en el Ecuador.
Authors: Guamán-Chisag José Luis
Published: May 2023

El uso del polígrafo es un tema controvertido más aún cuando de sus resultados depende la estabilidad laboral de los examinados. En el estado ecuatoriano el polígrafo, se utiliza como un componente dentro de las pruebas de confianza que se le practican a los servidores de la Policía Nacional. La reprobación de las pruebas de polígrafos ha determinado la permanencia de los servidores policiales en sus puestos los cuales han sido desvinculados de manera inmediata y definitiva. Se desconoce si el uso del polígrafo tanto en los procesos de selección aspirantes como en la evaluación de los miembros constituye una práctica legal y cuál ha sido su influencia en la desvinculación de servidores policiales como parte del proceso de depuración de malos elementos de las filas policiales. La metodología empleada fue la revisión bibliográfica y documental. Se emplea el método descriptivo-bibliográfico, se utiliza para el análisis la normativa legal asociada al objeto de estudio y estudios indexados en bases de datos. Las pruebas técnicas constituyen unos de los requisitos vigentes que conforman la evaluación del desempeño de los servidores policiales en Ecuador desde hace bastante tiempo, sin embargo, este es un tema que ha sido poco investigado.
