ABSTRACT Background: Spinal muscular atrophy (SMA) is a neurodegenerative disease of lower motor neurons associated with frequent occurrence of spinal deformity. Nusinersen is an antisense oligonucleotide that increases SMN protein level and is administrated by frequent intrathecal lumbar injections. Thus, spinal deformities and previous spinal surgery are important challenges for drug delivery in SMA. Objective: To report imaging methods used for Nusinersen injection in SMA patients. Methods: Nusinersen injection procedures in SMA types 2 and 3 patients who had previous spinal surgery were analyzed retrospectively to describe the imaging and puncture procedures, as well as the occurrence of complications. Results: Nine SMA patients (14 to 50 years old) underwent 57 lumbar punctures for nusinersen injection. Six patients had no interlaminar space available; in five of them, a transforaminal approach was used, and another one underwent a surgery to open a posterior bone window for the injections. Transforaminal puncture was performed using CT scan in three cases and fluoroscopy in the other two, with a similar success rate. One patient in the transforaminal group had post-procedure radiculitis, and another one had vagal reaction (hypotension). In three cases, with preserved interlaminar space, injections were performed by posterior interlaminar puncture, and only one adverse event was reported (post-puncture headache). Conclusion: In SMA patients with previous spinal surgery, the use of imaging-guided intervention is necessary for administering intrathecal nusinersen. Transforaminal technique is indicated in patients for whom the interlaminar space is not available, and injections should always be guided by either CT or fluoroscopy.

Published: March 2021

ABSTRACT Background: Cancer patients in general and glioblastoma patients, in particular, have an increased risk of developing complications from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and reaching a balance between the risk of exposure to infection and the clinical benefit of their treatment is ideal. The aggressive behavior of this group of tumors justifies the need for a multidisciplinary team to assist in clinical decisions during the current pandemic. Brazil is now ranked #2 in the number of cases and deaths from COVID-19 pandemic, and existing disparities in the treatment of neuro-oncology patients in Brazil will challenge the clinical and surgical decisions of this population, possibly affecting global survival. Objective: To search the literature about the management of glioblastomas during COVID-19 pandemic to guide surgical and clinical decisions in this population of patients in Brazil. Methods: We performed a systematic search on the PubMed electronic database targeting consensus statements concerning glioblastoma approaches during COVID-19 pandemic up to July 18, 2020. Results: When approaching glioblastoma during the COVID-19 pandemic, important parameters that help in the decision-making process are age, performance status, tumor molecular profile, and patient consent. Younger patients should follow the standard protocol after maximal safe resection, mainly those with MGMT methylated tumors. Aged and underperforming patients should be carefully evaluated, and probably a monotherapy scheme is to be considered. Centers are advised to engage in telemedicine and to elaborate means to reduce local infection. Conclusion: Approaching glioblastoma during the COVID-19 pandemic will be challenging worldwide, but particularly in Brazil, where a significant inequality of healthcare exists.

ABSTRACT Objective: to verify the validity and reliability of the Psychological Distress Scale for screening mental distress. Methods: a cross-sectional study with 75 elderly people. Psychological Distress scale and Self Reporting Questionnaire were used. Criterion validity was verified using Spearman’s correlation and diagnostic accuracy measures. Cronbach’s alpha coefficient was used to investigate reliability. Results: the total internal consistency of the Psychological Distress Scale was α=0.844. Concurrent validity between this instrument and the Self Reporting Questionnaire was ρ=0.722 (p<0.001). The best cut-off point for screening mental distress among elderly people was a total score greater than 14, with sensitivity equal to 75.47% and specificity equal to 85.0%. Conclusions: the scale was robust for screening mental distress, given its high reliability, in terms of homogeneity, and adequate criterion validity, whose best cut-off point for screening was a score greater than 14.

ABSTRACT Objective: to describe and analyze the scientific production on health care for Lesbians, Gays, Bisexuals, Transvestites, Transsexuals, Transgenders, Intersex (LGBTI+) and other variations of gender or sexual orientation living in Nursing Homes (NHs). Methods: a scoping review, in which PubMed, Web of Science, Scopus and Virtual Health Library databases were analyzed and studies from other sources were added. After assessment by two independent reviewers, 19 publications were selected to compose the sample. Results: the studies were grouped into two categories. Final considerations: NHs are configured as spaces that are not very inclusive, where LGBTI+ elders’ demands are not considered due to the cis-heteronormativity in force in these places. Training and awareness of health professionals on the LGBTI+ theme is a tool that can make such spaces more inclusive for this population.

ABSTRACT: Plant growth analysis can be used for soybean plants evaluation to identify morphologic changes caused by soil microbes after seed inoculation. The objective was to measure changes of inoculated soybean plants grown under regular field Brazilian production conditions. The experiment was carried out to compare 5 inoculation treatments: T1 (Bradyrhizobium japonicum and B. diazoefficiens), T2 (T1 and Azospirillum brasilense), T3 (T1 and Trichoderma asperellum), T4 (T1 and T. virens, and Bacillus amyloliquefaciens) and T5 (T1 and Penicillum bilaiae). Leaf area, shoot and root dry matter were measured at vegetative and reproductive growth stages. Results of this study validate the contribution of plant growth analysis of soybeans plants for identifying their responses promoted by the combined inoculation of their seeds with selected microbes. Also, the microbial effects on plant growth vary not only between microbes but also between parts of the plants and through the plant development stages. The introduction of different microbes in soybean rhizosphere combined with Bradyrhizobium sp. strains can contribute to increase crop dry matter productivity during its growing cycle.

Published: March 2021

ABSTRACT: Rumen development depends on the intake of solid food that is fermented into volatile fatty acids that stimulate the development of the rumen papillae in calves. The starter feeding can promote the growth of papillae in the rumen and as a consequence an earlier weaning. We evaluated the effects of calf starter on ruminal development, and productive response of lactating bull calves raised for meat in the tropics. Twelve male Brahman × Swiss American cross beef calves from a dual-purpose system were randomly assigned two treatments with six animals per treatment: milk-fed calves + Taiwan grass (Pennisetum purpureum, MT) and MT + calf starter, (MTS). Feed intake and growth were measured at 7-day intervals throughout until 210 d of age. At 90 days old, three calves from each treatment were harvested, and fluid and ruminal tissues were collected from the cranial, ventral, dorsal, and dorsal blind ruminal sacs for measurements of many papillaes per cm2 (NP), papillae length (LP) and papillae width (WP). Ruminal bacterial genotype identification was determined by amplicon generation with the Illumina platform. Calf starter-improved weight (Live weight, LW) and average weight gain (ADG) and NP, but, LP and WP was similar in both treatments (p < 0.05). In calves with starter feed treatment, we observed the bacteria Desulfonauticus autotrophicus sp. nov.that was not previously reported in ruminants. Use of calf starter showed benefit for calves with improved feed intake and rumen development because promoted a greater number of rumen papillae.
Ten years from propagule to mature plant of Butia purpurascens Glassman (Arecaceae): an endemic and endangered palm of the Brazilian Cerrado
Authors: Ressel K. , Guilherme F. A. G.
Published: March 2021

Abstract With occurrence mainly in the southwest Goiás, Butia purpurascens has fruits and leaves widely extracted by the regional population. Coexists with exotic grasses, frequent burnings and cattle’s grazing and trampling. Young individuals are rarely seen. We aim to provide information about propagules, seedling formation and the monitoring of saplings of B. purpurascens until adults in reproductive phase. Fruits were selected, measured and benefited after harvest. Of 6,000 fruits collected 3,112 were discarded for being perforated by Conotrachelus weevils. The experiment divided 2,600 fruits into 13 treatments, distributed in ripe and immature fruits, with and without pulp. In addition, we adopt mechanical and chemical break dormancy mechanisms, different storage periods and seeding depths. After sixteen months of monitoring, the formation of eleven seedlings was obtained without distinction of any treatment. Seedlings and saplings developed slowly, taking two years to emit the first metaphyll. Over time, ten individuals died, most from fungal attack. After ten years, the only surviving palm generated two inflorescences, which produced fruit. The inefficient seedling production and the slow development of saplings, combined with the impact of the extractivism and the high rate of predation of the pyrenes, suggest the low recruitment rate of the species observed, in natural conditions. This type of data is one of the important tools for creating guidelines for the species conservation. Therefore, we suggest considering the reclassification of B. purpurascens as a Critically Endangered species in the Official List of Threatened Brazilian Species of Extinction.
The present status, distribution, demography, and diet of the Dahl’s Jird
Authors: Bulut Ş.
Published: March 2021

Abstract Meriones dahli (Shidlovsky, 1962) was previously accepted to be a subspecies of M. meridianus (Pallas, 1773). However, it was later suggested that they are geographically isolated from each other. Although hybridological studies and differences in certain external characteristics support the idea that M. dahli is a separate species, there are still doubts on its species status, and the exact range of its distribution is not known. In this paper, we provide some taxonomic information about the species, and compare these with the information given in previous studies. We argue that some differences exist among Armenian population regarding external measurements. Recent studies indicate that M. dahli is currently only distributed in Turkey, as an endemic mammal species. We provide predictions about the distribution of M. dahli, and report the estimated population size to its maximum value. Food preference studies for this species, conducted under laboratory conditions, are also introduced for the first time. We discuss the ecological data obtained from field studies, and emphasize that the habitat of M. dahli is about to disappear. Consequently, the protection status of this species should urgently be changed to the CR category and conservation studies must be carried out immediately.

Legitimación de la violencia en parejas heterosexuales desde el género como una de las estructuras de práctica social
Authors: Idárraga Angélica Orozco , Caro Aura Aguilar , Macías María Amarís
Published: March 2021

Resumen Este artículo tuvo como objetivo develar las representaciones sociales de mujeres víctimas, agresores y prestatarios/as de servicios legitimadoras de violencia de pareja desde la estructura de género y práctica social en el distrito de Barranquilla, Colombia. Esta es una investigación cualitativa, con diseño fenomenológico-hermenéutico y teoría de representaciones sociales, que empleó como técnicas entrevistas a profundidad y análisis de contenido. Los hallazgos mostraron que la violencia para regular comportamiento, validación por celotipia, medidas conciliatorias y el supuesto agrado de las mujeres son formas legitimadoras de violencia en parejas heterosexuales. Se concluye que esta violencia se ha legitimado y naturalizado por el anclaje de representaciones, estereotipos y creencias, que ratifican el control de los hombres sobre las mujeres, en especial de su sexualidad y su cuerpo, como cosas de propiedad para el deleite y formas de autoridad, poder, control y desigualdad, que, a su vez, son permeadas por el modelo patriarcal.
Considerações sobre o impacto da covid-19 na relação indivíduo-sociedade: da hesitação vacinal ao clamor por uma vacina
Authors: Couto Marcia Thereza , Barbieri Carolina Luisa Alves , Matos Camila Carvalho de Souza Amorim
Published: March 2021

Resumo Desde março de 2020, quando a Organização Mundial de Saúde declarou que o mundo vivia uma pandemia de covid-19, acompanhamos um quadro sanitário sem precedentes nos últimos 100 anos. As medidas atuais contra a doença têm como objetivo o controle da transmissão e envolvem ações individuais e coletivas de higiene e distanciamento físico, enquanto a busca por uma vacina se apresenta como a esperança para vencer a pandemia. Considerando o contexto social de clamor por uma nova vacina, este ensaio crítico discute o paradoxo e as contradições da relação indivíduo-sociedade no contexto da covid-19 à luz da hesitação vacinal como fenômeno histórico e socialmente situado. Este ensaio aponta que as tomadas de decisão sobre (não) vacinar ou sobre (não) seguir as medidas preventivas e de controle da propagação da covid-19 são conformadas por pertencimentos sociais e atravessadas por desigualdades que tendem a se exacerbar. A infodemia que cerca a covid-19 e a hesitação vacinal refletem a tensão entre o risco cientificamente validado e o risco percebido subjetivamente, também influenciada pela crise de confiança na ciência. Percepções de risco e adesão a medidas de saúde extrapolam aspectos subjetivos e racionais e espelham valores e crenças conformados pelas dimensões política, econômica e sociocultural.

Published: March 2021

RESUMO A prevalência de meninos no fracasso escolar vem sendo salientada por vários autores e o fenômeno vem se acrescentando com a incidência do diagnóstico de TDAH no sexo masculino. Com base em dados coletados em um programa de extensão para crianças com queixa escolar, o presente artigo visa contribuir com uma articulação teórico-empírica acerca da perpetuação dos estereótipos de gênero na educação. O método incluiu a análise de 142 fichas de matrícula, 172 protocolos de observação e 10 registros de rodas de conversa. Além do predomínio masculino no atendimento, identificaram-se indícios de clichês sexistas, notadamente a agressividade física e a impulsividade para os meninos, e o culto à beleza para as meninas. A pesquisa salienta o papel dos educadores na perpetuação dos estereótipos de gênero e a fecundidade das rodas de conversa como instrumentos para sua identificação e desconstrução.

ABSTRACT Situation of study (SoS) has been reported as an excellent strategy to promote students’ significant learning. This work intended to demonstrate how a SoS on health education (“Knowing cancer: a way to life”) can be implemented within the co-creation (CoC) framework. The study was carried out in a middle school, with the participation of five groups: students (14-15 years old), teachers, future teachers, university teacher trainers and health professionals. The 10 activities were carried out in school and outdoors for five months, undergoing a process of self-reflexive cycle: “reflecting and planning”, “acting and observing”, and “analyzing and reflecting”. Transcripts of debates and of students’ and teachers’ texts were subject to content analysis. This study on a topic of health education demonstrated that the Situation of Study implemented in a co-creation process was very efficient for students to develop significant learning.
Retorno sobre uma antiga questão: Karl Marx e o estatuto dos Manuscritos econômico-filosóficos
Authors: Alves Wanderson Ferreira
Published: March 2021

RESUMO O artigo retoma a antiga questão do estatuto dos Manuscritos econômico-filosóficos de Karl Marx. Trata-se de um estudo teórico que se apoia na literatura de base sobre o tema e busca recuperar a história e as muitas disputas em torno dos Manuscritos de 1844, sobretudo em relação aos anos 1960-1970. O exame de algumas contribuições de três destacados autores do referido período - István Mészáros, Ernest Mandel e Lucien Sève - permite restituir a complexidade da discussão empreendida naquele contexto. O artigo conclui que, diante das questões tratadas, é importante ponderar sobre o conteúdo dos Manuscritos de 1844 no conjunto da obra marxiana, bem como é importante evitar duas posturas equivocadas, a de subestimar e a de superestimar esse incontornável texto de Marx.

Opinion: CASE Act will Harm Researchers and Freedom of Inquiry
Authors: Benson Sara , Vollmer Timothy
Published: March 2021

The Copyright Alternative in Small-Claims Enforcement Act of 2020 (CASE Act) was swept into law during the final days of 2020 as a part of the 5,500 page federal spending bill. In theory, the CASE Act aims to provide a venue for individual creators (such as photographers, graphic artists, musicians) to address smaller copyright infringement claims without spending the time and money required to pursue a copyright infringement lawsuit in Federal court. In reality, however, this additional bureaucratic structure created outside of the traditional court system is fraught with problems that will mostly incentivize large, well-resourced rightsholders or overly litigious copyright owners to take advantage of the system. At the same time, it will confuse and harm innocuous users of content, who may not understand the complexities of copyright law, and who do not know whether or how to respond to a notice of infringement via this small claims process. From our perspective, it will chill users who rely on crucial statutory exceptions to copyright, such as fair use, in their research and teaching activities.

Authors: Sakshi Bangia Ritika Thusoo, Sheilza Jain,
Published: March 2021

The advancement in the field of aerial robotics and control engineering has created many opportunities for the utilization of Unmanned Aerial Vehicles (UAVs).  Applications of UAVs from precision agriculture to delivering medicines and products at our doorsteps cannot be ignored. Quadrotors are the widely studied as sub-category of the rotor-type UAVs. Their ability to hover, vertical take-off and landing along with their small size and simple design make them suitable for many real-life applications like medicine delivery in containment zones struck with COVID-19. But under actuation caused due to four rotors to control six inputs creates instability in their flight. In this paper, Quadrotors and various Quadrotor applications are discussed. The various modeling and control techniques are discussed. Controlling techniques like LQR, LQG, PID and robust control is implemented for position, attitude and altitude control. Results for Proportional Integral and Derivative (PID) and Model Reference Adaptive Control (MRAC) of model generated using force-moment mathematical model are analyzed and compared using MATLAB Simulink. These control techniques are implemented for position, attitude and altitude control. In this paper, it has been concluded that MRAC performs better as compared to PID controller for position, attitude and Altitude control of Quadrotor.

The one major concern in the design of multiband patch antenna are the gain and bandwidth. Both gain and bandwidth of the multi band antenna can be improved for the better performance. In this paper a triangular multiband antenna is designed and the gain of the antenna is enhanced by the blend of reactive impedance surface and Frequency selective surface. The proposed antenna resonates 3.4 GHz, 4.2 GHz, 6.75 GHz,7.1 GHz, 7.5 GHz and 9.3 GHz with a better return loss and gain.
THE ROLE OF VIDEO CONFERENCING IN FOREIGN LANGUAGE LEARNING AMONG YOUNG STUDENTS
Authors: Medic Branko
Published: March 2021

During the coronavirus pandemic research on video conferencing effects on young language learners is more than ever relevant. During the sharp transition, educators need to fully understand the benefits and possible pitfalls of video conferencing, but also overcome resistance to change through knowledge. As author Philip Pullman rightly points out, “You cannot change what you are, only what you do.” This article summarised key research and provided evidence for and against the use of video conferencing in foreign language education. Thus, it gives food for thought and reflection, as well as directions for possible interventions.  However, the research was limited in terms of time and available literature, and the topic certainly requires more attention. In future, it is recommended to further research the use of multimodal interactions (sound, audio, text) in video conferencing, as well as coping strategies for dealing with the lack of interaction in the video conferencing-enabled classroom.
EARLY ACTION PREDICTION USING VGG16 MODEL AND BIDIRECTIONAL LSTM
Authors: Dr. Sammulal P Manju D, Dr. Seetha M,
Published: March 2021

Action prediction plays a key function, where an expected action needs to be identified before the action is completely performed. Prediction means inferring a potential action until it occurs at its early stage. This paper emphasizes on early action prediction, to predict an action before it occurs. In real time scenarios, the early prediction can be very crucial and has many applications like automated driving system, healthcare, video surveillance and other scenarios where a proactive action is needed before the situation goes out of control. VGG16 model is used for the early action prediction which is a convolutional neural network with 16 layers depth. Besides its capability of classifying objects in the frames, the availability of model weights enhances its capability. The model weights are available freely and preferred to used in different applications or models. The VGG-16 model along with Bidirectional structure of Lstm enables the network to provide both backward and forward information at every time step. The results of the proposed approach increased observation ratio ranging from 0.1 to 1.0 compared with the accuracy of GAN model.

Authors: Shweta Roy Himanshu Gulati,
Published: March 2021

In order to be forever etched in the minds of customers, Retail Store owners use Sensory Marketing techniques to provide a holistic experience to them at stores. How much a product or service is perceived by a customer is referred to as a sensory experience. The experience of a customer in a store has a huge impact on their buying decision and the image that the customer has of the company. In order to provide an experience that stays with the customers, retailers use techniques to influence the sensory experience of customers in a store. These experiences are results of external stimuli to our senses of touch, taste, sight, smell and hearing. This paper aims to study the factors that impact the holistic experience of consumers at a store. It aims to understand which sensory experience is of utmost importance to a customer in terms of providing a holistic sensory experience.  An effort is also done to identify and assess the holistic sensory experience of Indian retail industry customers, as well as to determine their understanding of sensory marketing strategies used in such retail shops.

There are plenty of ways to promote or sell a product, service, idea or an event, and only recently, there has been a surge in research that proves that visual aesthetics and design play a vital role in making an advertisement appealing or attractive to the consumer to buy or use.

The key purpose of this paper is to establish the principles or a framework that an advertiser keeps in mind while trying to appeal to the consumer’s perception of a brand offering. It shows how important visual design and imageries are in impacting the minds of the consumer. The people in the market are smart and they are able to identify the elements and traits in a design that makes it more appealing to them. And therefore, if a product’s communication appeals to its consumers, they are bound to purchase the said offering. Hence this study becomes very important for the brands, advertisers and the marketing industry as it tells them what makes their communications more attractive to their customers. Thus, the paper investigates how a customer’s opinion impacts their perception about the visual designs presented in the study.

The study allows the people of the sample group to pick their favoured design out of the options given based on a particular principal of design. The sample group is henceforth tested on various other principles of design theory and hence we establish the level of understanding the group possesses towards design and aesthetics of any product.     

The findings from empirical analysis indicates that visual designs of various ads tend to play a vital role when it comes to swaying the perception of consumers.

In was particularly observed in research that perceptive “matching” of target segment needs (desiring product being presented in a visually pleasing manner) and visual properties utilized in adverts (verbal or visual predominately) seems to be vital.

The utilization of images/visual design has an impact on the consumer’s perception as it is able to uplift recall value, motivate their attitude toward company’s promoted objects, and therefore harness their psychological intentions. Visual communication grabs attention as adverts have become so meta and complex in its efforts to use design & aesthetics to persuade customers and seize their focus.

Authors: Danh Nguyen Tan
Published: March 2021

Our living environment is increasingly polluted, not only because the amount of resources is increasingly being indiscriminately exploited, there are still many forms of production that pollute the environment, toxic substances which are difficult to decompose into the environment because of not-good human consciousness of some people. The improper collection and classification of daily-life waste is an issue that needs to be addressed. Besides, the situation of indiscriminate garbage disposal and many serious environmental pollution points is formed. Some people even bring domestic waste, dead animal carcasses to rivers and lakes right where they live. Facing the increasing risks of natural environmental pollution, Vietnam needs to promote the education of environmental protection awareness for all people in general and primary school students in particular. Students are the future generation of the country, are the decisive owners for the development of the whole society and are also the people most affected by natural resources and the environment. The article uses survey methods and analyzes data from journals and recent studies. The results show that we need to take action today so that students feel responsible for protecting resources and the environment for a clean and green world.

Published: March 2021

The image watermarking is widely used to provide the security. This paper provides the conceptual framework on image watermarking which is widely used for security purpose within the epoch of data and communication technology. Detailed discuss has been provided on the basis of the three phases. In the first phase of present paper focus has been made on image watermarking and data set will be prepared on which watermarking technique will be executed. Second phase need to locate a specific watermarking technique [LWT- WALSH HADMARD-SVD] which will provide appropriate results in term of PSNR and processing time. In second phase various attacks will be tested on images so that implemented method must stand against various attacks. Last phase emphasise on reverse process will be executed to extract cover and watermark image. Proposed technique is based on the secure encryption watermark .It is associated with image encryption. The encryption algorithm had been introduced in which watermarking information was based on the size of an image. It is clear from the outcomes of the hybrid proposed technique shows that it provides more security than the existing technique. Proposed techniques provide high level of security as compared to existed technology.

Social Danger of the Crime: Constitutional Law and Criminal Law Analysis
Authors: Guzeeva O. S.
Published: March 2021

In the Russian legal system, the crime, unlike other wrongs, is characterized as the act that has specific, namely criminal, public danger. Criminal liability in contrast to administrative liability is established for cases of high public danger. Turning to the meaningful characteristic of the phenomenon of public danger, the Russian doctrine proposed a number of theoretical constructions that in modern conditions, taking into account the need for updating the methodological framework of criminal law, can and should be reinterpreted and, to some extent, rediscovered.

Parameters of the “criminal” danger are not originally determined; they do not have clear evidence and criteria, and in modern conditions they cannot be calculated mathematically accurately. It is hardly possible to determine empirically the minimum threshold at which “crime begins”, since this task is political rather than experimental and cognitive, and it is resolved in the course of implementing the criminal policy of the State. Being a characteristic of all offenses, public danger has special quantitative parameters allowing us to assert specific criminal public danger that can be presented as a generalized indicator of the risk of a wrongful act, its actual or projected consequences and the identity of the perpetrator. The danger of a wrongful act serves as a starting point in assessing the risk of the crime at the lawmaking and law enforcement levels, assessing the risk of the wrong and of the crime that represent mismatched assessment practices. The risk created by the wrong depends on the balance between two significant factors: (a) the content and hierarchy of constitutional values at which the wrongful act is directed to cause harm; (b) characteristics of the threat emanating from the wrongful act that must be real, valid and must be confirmed by the specific actions or omissions of the wrongdoer.
