Published: October 2022

Em diversas cidades brasileiras é observada a presença de moradias em terrenos com declividade, inclusive em áreas de preservação permanente (inclinação superior a 30%). Alguns modelos físicos vêm sendo utilizados na determinação de mapas de suscetibilidade a deslizamentos, sendo o mais consolidado o Shalstab. Este estudo propõe a aplicação do Método dos Taludes Infinitos para a geração de um mapa de suscetibilidade a deslizamentos translacionais para a Microbacia do Itacorubi, região central de Florianópolis. Para a determinação dos parâmetros de resistência ao cisalhamento (c e ϕ) foram realizados ensaios de cisalhamento direto e Borehole Shear Test (BST), e para as classes de suscetibilidade que serão atribuídas às unidades, foram utilizados os fatores de segurança estipulados pela NBR 11682. Foram ainda consideradas duas possibilidades de formulação, com e sem percolação. Estas possibilidades de análises foram aplicadas diretamente em SIG onde é possível obter a inclinação real do talude e gerar as classes de suscetibilidade a deslizamentos. Os mapas resultantes foram comparados ao mapa de suscetibilidade de Christ (2019) obtido com base no modelo Shalstab.

Published: October 2022

This study criticizes the Community Service Program in the field of accounting as muhasabah (self-introspection) and offers a new concept of knowledge. The approach used is humanist-theocentric. Criticism of the Community Service Program in the field of accounting only leads to one benchmark that is secular. The logical consequence of the bankable the Community Service Program is that it contributes to an increase in inflation. The new form of PKM in accounting is to improve people's natural abilities such as brain performance and communication skills. Brain performance is used for the most classic accounting practices and communication skills are used to get additional venture capital from God through relatives, and communities. The new form of the Community Service Programneeds to involve other disciplines.

Published: October 2022

Premarital sex is one of the most complex adolescent problems. Universities that are far from home, make female students have to rent temporary housing which results in a lack of supervision from parents, and increasingly free association can exacerbate sexual behavior in female students. This type of qualitative research with a quasi-qualitative approach. Determination of informants by a snowball with a total of 7 informants. The result of the study is that the main cause of premarital sex occurs because self-control then lifestyle, religious understanding, parental relationships, and the media also encourage premarital sex. The premarital sex behavior of female students is very vulnerable. The intensity of sexual intercourse is quite intense, they do not use contraception and they have premarital sex in boarding houses, in hotels, and even in private homes. The impact of premarital sex on teenagers or college students is that they experience a psychological impact, namely regret, but feelings have already made them keep doing it.
Minimizing Peak to Average Power Ratio in OFDM System with WHT and Log Companding
Authors: Achebe P. N.
Published: October 2022

Orthogonal Frequency Division Multiplexing (OFDM) suffers the effect of Peak to Average Power Ratio (PAPR) that reduces the strength or power of radio frequency (RF) signal at the transmitter and which also pushes the performance of transmitter amplifier into distortion. In order to minimize the effect of PAPR in OFDM, this paper proposed a system that precodes the OFDM signal using Walsh-Hadamard Transform (WHT) and Log function companding algorithm. Simulations were conducted in MATLAB environment while varying the number of subcarriers, N = 16, 64, 128, 256. simulation results indicated original OFDM revealed high PAPR in transmitted signal for the different number of subcarriers (N) such that for N =16, 64, 128, and 256, resulting in 7.964dB, 8.885 dB, 9.548 dB, and 9.961 dB respectively. With the introduction of WHT-Log companding scheme, the PAPR of OFDM signal was significantly reduced to 4.775 dB, 4.285 dB, 4.517 dB, and 4.602 dB by a percentage improvement of 40%, 51.8%, 52.7%, and 57.8% for N = 16, 64, 128, and 256 respectively. As a result, from the simulation results, the proposed system can be said to have largely reduced PAPR in OFDM system using a scheme with significant computational complexity.

The development of the Bangabandhu Satellite-1 has changed the direction of Bangladesh's satellite communication research. Bangladesh's dream project was the Bangabandhu Satellite 1. This satellite's primary goal is to maintain effective internet and communication services in remote places. First of all, we must concentrate to the depth of satellite communication system and its process to reach any conclusion. Our main goal of the research is to recognize a feasibility review on Bangabandhu satellite-2. So, for the feasibility studies we reviewed the most promising technical parts of Bangabandhu satellite-1. Here, we only focused the certain parts of the satellite such as coding, modulation, battery, purpose of ground station and the benefits of the satellite communication system. Then we moved on the main parts of the Bangabandhu satellite-2. As, Bangabandhu satellite-1 was Geosynchronous equatorial orbit (GEO) communication satellite and Bangabandhu satellite-2 will be Low Earth Orbit (LEO) observation satellite (LEO) so, some of configurations between them might be changed. Furthermore, we largely focused on Facts, efficiency, performance and noticeable difference between two satellites.
G-Jitter Effects on Transient Natural Convection Couette Flow in a Vertical Channel with Convective Boundary Condition
Authors: Bako Ponnan , O.Ajibade Abiodun
Published: October 2022

This article investigates the effects of g-jitter on transient natural convection Couette flow in a vertical channel. Fully developed laminar time dependent flow is considered. The flow formation is caused by the buoyancy force arising from the temperature gradient as a result of asymmetric heating of parallel plates as well as constant motion of one of the plates. The method of Laplace transforms is used to obtain the expressions for temperature and velocity which are used to compute the Nusselt number, skin-friction, mass flux and Mean temperature in Laplace domain then the Riemann-sum approximation is used to invert our expressions from Laplace domain to time domain. During the course of investigation, it was found that the influence of heat generation/absorption parameter on the rate of heat transfer on one plate is the reverse of the influence on the other plate. Increase in convective coefficients of the bounding plates constitute an enhancement to heat transfer, skin friction, mass flux as well as mean temperature within the channel

According to the report by the United Nations Office on Drugs and Crime (2020), the number of drug-users aged 12-64 has exceeded 275 million people, which accounts for 5.4% of the globe’s population. The highest number of drug addicts has been registered in the United States of America − 28.6 million; in the European Union – 17.4 million, while Russia accounts for 6 million, with 11.8 million deaths registered annually worldwide, that are directly or indirectly related to drug abuse. Tightening anti-drug measures along with higher demand for drugs from low-income groups of people result in expensive “classical” drugs being replaced with various substitutes, medicines and synthetic drugs, including phencyclidine. Chromatographic methods play a major role in the expert evaluation of narcotic drugs, toxic substances and their metabolic products in biological media, whereas the use of gas and liquid chromatography-mass spectrometry allows identifying – with a high reliability level – most compounds that are relevant in terms of analytical and forensic toxicology. This paper offers a comparative analysis and an overview of optimized methods to be employed to detect phencyclidine and its derivatives in biological fluids and tissues. There has also been toxicokinetics and biotransformation of phencyclidine studied, as well as a drip chemical analysis of phencyclidine carried out. The detection of phencyclidine and its derivatives through chromatographic methods has been improved. The obtained outcomes can be used for differentiating phencyclidine and its derivatives in forensic chemical and chemical-toxicological studies of biological material.

The society nowadays is being exposed to constant high toxicological stress. The expanding range of substances people use in their daily life, a growing drug addiction rate, newly developed highly active medicines, environmental and man-made disasters, the chemicals used to commit acts of terror, the progress of chemically-induced diseases – all these result in a steady increase in the number of poisoning cases. The detection of toxic substances in the body of someone who suffered poisoning is the leading area in diagnosing disease of chemical origin. Apart from clarifying the diagnosis, important is to identify the indications for hospitalization, the choice of the detoxification method, as well as that of the antidote therapy. Given that, chemical and toxicological studies aimed at the detection, identification, and quantification of a wide range of toxic substances in objects of biological origin are relevant and enjoy respective demand. This paper offers a comparative analysis of preliminary research methods, as well as extraction from internal organs, of biological fluids and physical evidence to be taken into account through chemical and toxicological analysis carried out to detect medicinal, narcotic substances and metabolites thereof. The research objects here were blood, urine, bile, internal organs, brain from human corpses of males and females, aged 21 to 65, with different causes of death, as well as physical evidence (residue of medicines). The results of this study can be used to select methods for detecting toxic substances at the stages of forensic chemical examination.

Authors: Dzampaeva Zhanna
Published: October 2022

Background: The global prevalence of periodontal disease in adults is estimated up to 60-90%. Thus, development of new methods for diagnosis and treatment of periodontitis with their approbation on animal models is important. Aim: To create an experimental model of periodontitis in rats for the best possible simulation of clinical manifestations in humans according to the current understanding of the etiology and pathogenesis of this disease. Methods: The experiment was performed on 20 male Wistar rats (230±20 g). According to the proposed methodology, periodontitis was modeled by placing a metal ligature on the gingival margin of the lower incisors in a figure eight-shaped manner and fixing it to the alveolar bone thus destroying the ameloblastic epithelium. Periodontal inflammation was studied clinically and histologically. Microcirculation parameters were analyzed by Doppler ultrasound. Results: The use of the proposed periodontitis model was associated with inflammation, hyperperfusion causing an oxidative stress and periodontal destruction: Vas, Vakd and Vam significantly increased by 40.0% (p=0.007), 60.63% (p=0.005) and 83.33% (p=0.005), respectively. Also, there were significant decreases in the Gosling (PI) and Stewart (SD) indices: 63.82% (P=0.008) and 20.39% (p=0.005). Conclusion: The developed model is easily reproducible and similar to the clinical characteristics of periodontitis in humans, decrease the modeling time to 7 days thus simplifying the new developments in diagnosis and treatment of periodontitis.

“Cloud” is a collective term for a large number of developments and possibilities. It is not an invention, but more of a “practical innovation”, combining several earlier inventions into something new and compelling. A cloud computing platform dynamically provisions, configures, reconfigures, and de provisions servers as needed [8]. Servers in the cloud can be physical machines or virtual machines. Security is a critical issue in cloud computing due to the variety of IT services that can be provided through a cloud environment. This paper focuses on the aspect of searching keywords over encrypted data while maintaining integrity of the data. Using a traditional algorithm like AES. Unlike traditional searching algorithms, here we try to implement a fuzzy logic which is based on a NLP technique called N gram. This fuzzy keyword searching significantly increases the efficiency and safety over cloud. This will keep the searching time efficient and acquire great results. The n-gram logic will be used to make sets of keywords which will used in the search implementation. To achieve more accurate results, Jaccard Coefficient will be used to find the similarity between the sets of keywords and rank them based on that. The purpose of this paper is to improve the traditional keyword search over encrypted data using cloud computing using advanced algorithms without compromising over security. Through rigorous security analysis, we show that our proposed solution is secure and maintains the privacy of the file server while efficiently using the fuzzy logic

The rapid rise in hacking and computer network assaults throughout the world has highlighted the need for more effective intrusion detection and prevention solutions. The intrusion detection system (IDS) is critical in identifying abnormalities and assaults on the network, which have grown in size and scope. IDS prevents intruders from gaining access to information in the field of network security as a result. The use of IDS is critical for detecting various types of attacks. Because the network traffic dataset contains a large number of features, the process of selecting and removing irrelevant features improves the accuracy of the classification algorithms. For the fact that a large dimension allows us to include more data, the feature vector can be built by combining different types of features. Contains a lot of redundant or irrelevant data can cause confusion. Over-fitting issues and a decrease in the generalization capacity of the model. Solving such a problem necessitates a sequence of feature selection methods the boosted maximum relevance maximum distance (BMRMD) method can report on the contribution of each feature as well as the predictive accuracy based on the best feature set. As a result, the best features in this study were chosen using the BMRMD assesses feature redundancy to determine feature relevance to the target class based on optimum ensemble feature classification

Study exploring the urban world deployment of LoRa waves using the ESP32  microcontroller

Secure communication over large distances is not possible with conventional Wifi or cellular networks. A long range secure communication model is required for such conditions. This paper puts forth a communication model suitable for information exchange over a such large distances. LoRa (Long Range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. The typical range provided by LoRa can be up to three miles (5km) in urban areas, and up to 10 miles (15 km) or more in rural areas of line of sight. LoRa’s high range is characterized by high wireless link budgets of around 155 dB to 170 dB. ESP32 is a series of low-cost, low-power system on chip microcontrollers. The LoRa modem is available as the SX127X module which is connected to the ESP32 boards. Data security is ensured by performing data encryption on the sender board and data decryption on the reciever board. The algorithms for encryption and decryption shown in this article is the AES method. This paper also explores the possibility of hijacking the data while transmitting and shows which algorithms are immune to attacks and which can be easily broken. The use cases for such a communication system could be for secure 2-way communication, communication in remote areas where cellular and Wifi are not available, effecient control of IOT devices over a much larger distance, control of unmanned ground and aerial vehicles, etc.
Identifying Effective Trajectory Predictions Under the Guidance of Trajectory Anomaly Detection Model

Published: October 2022

Trajectory Prediction (TP) is an important research topic in computer vision and robotics ﬁelds. Recently, many stochastic TP models have been proposed to deal with this problem and have achieved better performance than the traditional models with deterministic trajectory outputs. However, these stochastic models can generate a number of future trajectories with different qualities. They are lack of self-evaluation ability, that is, to examine the rationality of their prediction results, thus failing to guide users to identify high-quality ones from their candidate results. This hinders them from playing their best in real applications. In this paper, we make up for this defect and propose TPAD, a novel TP evaluation method based on the trajectory Anomaly Detection (AD) technique. In TPAD, we ﬁrstly combine the Automated Machine Learning (AutoML) technique and the experience in the AD and TP ﬁeld to automatically design an effective trajectory AD model. Then, we utilize the learned trajectory AD model to examine the rationality of the predicted trajectories, and screen out good TP results for users. Extensive experimental results demonstrate that TPAD can effectively identify near-optimal prediction results, improving stochastic TP models’ practical application effect.
Análisis ontológico de la muerte materna desde la concepción del pluriverso
Authors: Reyes Guillén Flor Ivett
Published: October 2022

El propósito del presente artículo es analizar a la muerte materna como un problema de salud pública y como un problema social de alto impacto, con consecuencias como la orfandad y el impacto económico en las familias. El diseño metodológico es de carácter mixto basado en entrevistas a profundidad, matematización de la realidad y la propuesta de indicadores para la sistematización de las intervenciones para la atención a la salud materna en espacios de diversidad cultural. Dentro de los resultados más importantes están la visibilidad de barreras culturales para la comunicación entre los actores sociales involucrados en la atención a la salud materna y su búsqueda. 

Dentro de las limitaciones de la investigación está la necesidad de ampliar la zona de estudio y compararla con otras zonas del estado y el país. Los hallazgos giran alrededor de las necesidades de contribuir a la interculturalidad que favorezca a los grupos étnicos que interactúan en búsqueda de la salud pública y el control de la mortalidad materna.

Literatura: Perpendicularidad entre emoción y mente
Authors: Banquez Maturana Ana Gabriela
Published: October 2022

En este trabajo se abordará el estudio literatura, y la perpendicularidad entre emoción y mente, desde una perspectiva neuropsicológica. Dicha iniciativa conlleva a la búsqueda de conceptualizaciones sobre la literatura interrelacionada con otros conceptos, tales como emoción y mente. Se manifesta la necesidad de redefnir qué se entiende por estas categorías en la investigación sobre la literatura; más cuando las expresiones literarias son creadas a partir de las concepciones de realidad o fantasía en las personas.

A su vez, se busca propiciar el desarrollo de la comunicación escrita y creativa en las personas como una fuente de liberación del pensamiento, a partir del pronunciamiento de las ventajas que dicha actividad causaría en la vida de las personas para su equilibrio emocional, al liberar las ideas y sentimientos reprimidos.

Así mismo, el aprovechamiento de sus habilidades de lectoescritura para la creación de propiedad intelectual que queden registradas en su historia de vida.

El acceso a un ambiente sano es un derecho humano, ubicado en el grupo de los DESC, con una alta complejidad de su reclamación, pues al ser un bien jurídico distinto a los demás la naturaleza necesita de una tutela diferente; recordemos que la naturaleza es sujeto activo, pues no únicamente afecta a los seres humanos, sino a otros habitantes del planeta, debiendo prevalecer el interés colectivo sobre el individual.

Aun cuando varios Estados han positivado los derechos de la naturaleza dentro de sus ordenamientos jurídicos, como lo ha hecho el Estado ecuatoriano en la Constitución del 2008, es notable que su protección sigue siendo débil, y para fortalecer estos aspectos el Estado deberá adoptar políticas públicas efcientes que le permitan fscalizar las actividades particulares, en las que se pretenda afectar al medio ambiente, lo que permitirá garantizar el derecho a un ambiente sano a toda la población.

Estos derechos ambientales, así como la degradación o modifcación de los ecosistemas, han logrado que el derecho proteja el ecosistema, lo cual ha dado el origen a la relación entre los derechos humanos y el ambiente, lo que ha alcanzado a todos los países del mundo, planteando retos que los Estados deben afrontar con todo lo que ello implica, es decir, hacer sostenible el ecosistema en los próximos años.

El compromiso no únicamente es del Estado, ni de las instituciones especializadas en la materia; es una responsabilidad de toda la población, dado que el derecho a un ambiente sano constituye una de las luchas sociales para conseguir su exigibilidad, para garantizar su goce efectivo a fn de que las personas tengan la posibilidad de plantear un reclamo individual para exigir al Estado el cumplimiento del derecho a gozar de un ambiente sano.
Megaesôfago em cães - revisão de literatura
Authors: Oliveira Ygor Garcia de , Soares Aline Fernandes , Novais Adriana Alonso
Published: October 2022

O megaesôfago é causado pela presença de hipomotilidade e consequente dilatação esofágica. O objetivo deste trabalho é realizar uma revisão literária de megaesôfago em cães, discutindo os principais sinais clínicos, diagnóstico e tratamento da doença. O principal sinal clínico associado a doença é a presença de regurgitação em animais jovens e o subdesenvolvimento do filhote após o desmame. O diagnóstico do megaesôfago é realizado com base nos sinais clínicos e principalmente com radiografia contrastada de região de tórax, que evidenciará dilatação esofágica. Até o seguinte momento não há cura ou tratamento clínico-cirúrgico que solucione a debilidade esofágica congênita. Inicialmente, deve-se realizar o tratamento dietético-conservador, diminuindo os riscos de dilatação e aspiração de conteúdo alimentar. O animal deve ser alimentado com alimentação pastosa, em uma plataforma elevada de maneira que o paciente fique em estação, com apoio dos membros posteriores, fazendo com que a gravidade auxilie a passagem do alimento através do esôfago ao estômago. O prognóstico do megaesôfago é reservado devido a natureza desta patologia, as complicações envolvidas e a falta de um tratamento definitivo. Embora o diagnóstico precoce auxilie no tratamento, a expectativa de vida é baixa, sendo aproximadamente um ano de idade.

Published: October 2022

The aim of the present study was to ascertain the accuracy of the Prefrontal Symptoms Inventory (PSI-16) for patients with probable Alzheimer, as well as to compare it with the Mini Mental State Examination (MMSE) and the Frontal Assessment Battery (FAB). The study included 159 elderly people, aged over 60 years, 50 with a diagnosis of probable Alzheimer and 109 without the pathology. In the total sample, the cut-off point of the PSI-16 was > 19 points, with sensitivity and specificity moderate. Accuracy in the group with a ³ 8 years of education was superior in all instruments. The AUCs of PSI-16 and MMSE remained similar, the SE of all instruments increased, and the SP obtained a decline, considering the elderly over 70 years old. PSI-16 is a self-report instrument suitable for tracking behavioral problems related to the prefrontal cortex, with little impact from age and education level.
