The National Commission to Prevent and Eradicate Violence Against Women reports that gender violence alerts in Mexico have been declared in 19 states and 4 states are waiting to be declared in 2019. The crime incidence rate published by INEGI shows that for every 100 thousand inhabitants, more than 11 thousand have been victims of robbery or assault on the street or public transport. Various systems have been developed whose objective is to reduce insecurity rates through the use of applications on mobile devices, however it is not considered a natural activation, since everything is done through virtual user interfaces. The developed system consists of an App on the mobile device and a hardware with wireless communication via Bluetooth 4.0 (Bluetooth low energy consumption) and a panic button using wearable technology. The activation is carried out through a panic button located on the smart garment, which allows the location to be sent through social networks, so their impact in emergency situations is explored.

Social tourism is a branch of tourism that seeks to ensure that all people have the opportunity to travel, and in this way create a development in the community where such programs are carried out as well as increase domestic tourism, and thereby fulfill the universal right to have vacations. In Mexico, not everyone has access to enforce this right since travel has become an activity only for a group of people. There is not enough information in studies about the Mexicans travel motivations, which is why it is important to identify the reasons that lead people to travel or what limits them to travel. This research is quantitative, exploratory and descriptive, where 300 subjects were studied, using the survey as a method of collection which resulted that most of the subjects travel to obtain new experiences, for recreation, to learn about new cultures and they do not travel due to lack of time and money, important data for the creation of new tourist offers that are available to all Mexican families, looking for the introduction of social tourism to Mexico.

Published: September 2020

In recent years, the Ministry of Public Education (SEP) has established new standards for the issuance of Digital Bachelor Degree Certificates titles by educational institutions and their registration with the Directorate General of Professions (DGP). Currently, the Technological Institute of the South of Guanajuato (ITSUR) through the academic body of Software Development under software engineering methodologies, is completing the first stage of developing an application to issue, sign and register digital bachelor degree certificates before the DGP. This application does not have any module that allows access to the student or general public interested in their validity. Therefore, it is required to develop new modules that require the student to follow up on the process, download the degree certificate and the graphic representation, as well as allow those employers or affected to verify the validity of a degree. The methodology to use will be iterative and incremental, to divide the project into iterations that generate increases in value and achieve stabilization in less time. This new version will have greater impact, as it may be distributed to other Technological Institutes that have implemented the Integral School Control System (SICE) owned by ITSUR and thus reduce the gap in the issuance of digital degree certificates.

Authors: Ramos Andrade Beraldo Mariana , L. S. B. Varzim Fernanda , Hildebrand Pulz Lidia
Published: September 2020

O linfoma é uma neoplasia caracterizada pela proliferação de células linfoides malignas, que pode se desenvolver em qualquer órgão, acometendo inicialmente linfonodos, baço e fígado. Sua causa não é bem elucidada, porém acredita-se na etiologia multifatorial, fatores genéticos, deficiência imunológica e carcinógenos químicos. Existem quatro classificações anatômicas para o linfoma: multicêntrico, alimentar ou digestiva, mediastínico e extranodal, sendo que 80% dos casos em cães são classificados como linfomas multicêntricos. O diagnóstico é baseado em análises citológicas, histológicas e biologia molecular, que auxiliam no estabelecimento do prognóstico do animal considerando o grau de malignidade do linfoma e o tipo celular de origem. Os exames laboratoriais, como os perfis hematológicos e bioquímicos, fornecem dados para o acompanhamento do animal, acometimento e estadiamento da doença. Perante o exposto, constata-se que o linfoma é uma afecção de grande relevância dentre aquelas que acometem cães, portanto, este estudo tem o objetivo de aliar a base teórica frente à apresentação clínica do linfoma, fornecendo o conhecimento das principais alterações descritas para gerar um diagnóstico precoce, estabelecendo uma ponte de sucesso com o clínico e permitindo ao paciente melhor qualidade de vida e sobrevida perante a doença.

Enhancing construction safety management through edge computing: framework and scenarios
Authors: Chen Ke
Published: September 2020

With the increasing complexity of construction activities, timely data collection and analysis become the prerequisites for supporting safety management decisions. However, conventional methods generally use centralized computing platforms, which might encounter challenges such as high latency and resource consumption. The recent development in edge computing brings new opportunities to address these challenges by offloading parts of the computing tasks from the center to the edge. This study thus attempts to develop a comprehensive edge computing framework to enable real-time construction safety management (CSM). Existing architectural frameworks of edge computing are reviewed, based on which an edge computing framework suitable for CSM is proposed. Then, the deployment of the proposed framework is elaborated through three safety management scenarios derived from actual construction projects. This study suggests that edge computing can improve the efficiency and quality of CSM. This study will also inform future studies on exploring the applications of edge computing in other construction management areas.

Published: September 2020

A ovinocultura é uma importante atividade pecuária no Sul do Brasil, propiciando renda e contribuindo para a reprodução social de pequenos produtores no meio rural. Dentre as fases existentes dentro de um sistema de produção de carne ovina, a terminação vem sendo amplamente discutida nos últimos anos, em razão de sua importância na garantia de um produto de qualidade e que atenda à demanda dos consumidores. Sendo assim, a presente revisão de literatura tem por objetivo abordar as particularidades de alguns sistemas de terminação de ovinos no Sul do Brasil, a exemplo da utilização de pastagem de Panicum maximum cv. Aruana, do sistema silvipastoril e do confinamento. Os sistemas a pasto são predominantes na Região Sul do Brasil, em razão das grandes extensões territoriais e por serem alternativas menos onerosas a curto prazo. O sistema silvipastoril apresenta um custo inicial mais elevado quando comparado ao anterior, mas a longo prazo pode ser mais rentável por associar duas atividades, a pecuária e a silvicultura. Entretanto, ambos os sistemas podem não atender à necessidade nutricional de animais em terminação ao longo de todo o ano, sendo necessária a utilização de suplementação. Por outro lado, o confinamento apresenta um elevado custo inicial, mas pode ser uma importante ferramenta para garantir a regularidade de oferta de carne ao longo do ano, além de animais terminados neste tipo de sistema apresentarem bons resultados produtivos.

Naphthalene diimide bis-guanidinio-carbonyl-pyrrole as a pH-switchable threading DNA intercalator
Authors: Jana Poulami , Šupljika Filip , Schmuck Carsten , Piantanida Ivo
Published: September 2020

A novel naphthalene diimde analogue (NDI) equipped at the imide positions with two guanidinio-carbonyl-pyrrole (GCP) pendant arms interacted significantly stronger with ds-DNA at pH 5 than at pH 7, due to reversible protonation of the GCP arms. This was consequence of a pH-switchable threading intercalation into ds-DNAs only at pH 5, while at neutral conditions (pH 7) NDI-GCP2switched to the DNA minor groove binding. Intriguingly, NDI-GCP2was at both pH values studied bound to the ds-RNA major groove, still showing a higher affinity and thermal denaturation effect at pH 5 due to GCP protonation. At excess over the DNA/RNA conjugate NDI-GCP2showed also aggregation along the ds-polynucleotide and AFM and DLS demonstrated that NDI-GCP2has pronounced ds-DNA condensation ability.
TOWARDS A SYSTEM OF COGNITIVE ELEMENTS UNDERLYING LANGUAGE SYSTEMS
Authors: Васильев Валерий Иванович , Никитинская Лариса Владимировна
Published: September 2020

В статье предпринята попытка выделить когнитивные признаки (элементы), создаваемые работой сознания и лежащие в основе языковых категорий, систем и подсистем. Возникновение когнитивных элементов прослеживается с использованием метода интроспекции в ходе бинарных операций, проводимых при восприятии с помощью коренного бинарного тензора, на основе положений психомеханики Гюстава Гийома. В результате выделено шесть последовательных стадий развития когнитивного образа, приводящих к осознанию когнитивных элементов, которые являются базовыми для системы языка и предусматривают возможность дальнейшего расширения. Постулирована возможность выхода с любой из основных стадий развития когнитивного образа в иные измерения с последующей цепочкой операций коренного бинарного тензора параллельно главной линии последовательности образования когнитивных элементов.

Elementary cognitive features underlying language systems are identified by applying the operations of the binary radical tensor to the act of perception following the principles of psychomechanics outlined in Gustave Guillaume’s works. The resulting features called cognitive elements are hierarchically structured and comprise the following levels: occurrence, stasis/kinesis, indeterminate/determinate kinesis, punctual/repetitive occurrence, single/multiple quality, external/internal pivot. A transition can be made from each of the cognitive elements to launch another sequence of binary operations.
DIFFERENTIATION OF APHORISTIC GENRES OF LEZGIN FOLKLORE
Authors: Гашарова Аида Руслановна
Published: September 2020

В данном исследовании произведена попытка разграничения афористических жанров лезгинского фольклора: народных пословиц, поговорок и загадок. Автором рассматриваются принципы их деления. Объектом исследования являются афористические жанры лезгинского фольклора, поскольку наряду с остальными жанрами устно-поэтического творчества они занимают видное место в фольклоре с присущей им распространенностью повествования. Исследование представляется весьма показательным и в плане выявления специфики и взаимодействия трех жанров, входящих в одну группу: пословиц, поговорок и загадок. Лезгинские пословицы - крупицы мудрости, меткие слова, которые имеют обобщающий характер и заключены в сжатую и выразительную форму. Пословицы имеют определенную структуру и отличаются внутренним художественным единством. Лезгинские поговорки - это меткие образные выражения, которые обогащают разговорную речь, придают ей самобытность, эмоциональную насыщенность; это метафоризация и аллегория без нравоучения. В них в косвенной, скрытой словесной форме говорится о ком-либо или о чем-либо, передается отношение говорящего к сказанному. Загадки - это замысловатые описания какого-либо предмета или явления, созданные с целью испытать сообразительность человека, равно как и с целью раскрыть ему глаза на поэтическую красоту и богатство предметно-вещественного мира. Цель исследования - показать различия между этими жанрами и их общие черты.

This study attempts to distinguish between aphoristic genres of the Lezgin folklore: folk proverbs, sayings and riddles. The author considers the principles for their differentiation. The object of the study is the aphoristic genres of the Lezgin folklore, since, along with other genres of folklore, they occupy a prominent position with their inherent narrative prevalence. The study seems very illustrative in terms of identifying the specifics and interaction of the three discussed genres (proverbs, sayings and riddles) which fall into the same group. The Lezgin proverbs are the grains of wisdom, striking words that have a generalizing character and are enclosed in a concise and expressive form. Proverbs have their own structure and are distinguished by their internal artistic unity. The Lezgin sayings are accurate figurative expressions that enrich spoken language, make it original and emotionally rich; it is metaphorization and allegory without moralizing. These expressions in an indirect, hidden verbal form speak of someone or something and express the speaker’s attitude to what is being said. Riddles are poetically intricate descriptions of an object or phenomenon, aiming to test a person’s quick wits, as well as to reveal the poetic beauty and richness of the material world. The subject of the study is to show the differences and similarities of these genres.

An Analysis of Time-Series Models for Age-Specific Mortality Rates in India
Authors: Sen Aritra , Dutta Shalmoli
Published: September 2020

Mortality is a continuous force of attrition, tending to reduce the population, a prime negative force in the balance of vital processes (Bhasin and Nag, 2004). Sample Registration System (SRS) serves as the only source of annual data on vital events on a full scale from 1969-70 in India. Few studies have examined the trends and patterns of mortality across time and regions in India (Preston and Bhat, 1984). The Under 5 Mortality Rates (U5MR) can be seen to decrease by more than half from 1970 to 2017 but in contrast little is known about the mortality patterns of the older children (5-9) and young adolescents (10-14), and not many studies have been done on their changing trends (Masquelier et al., 2018). Using the annual data for the 5-14 age, the trend of decline in the mortality patterns is studied from 1970 to 2013. The linear trend in the time series plot suggests analysis using time series models AR(p), MA(q), ARMA(p,q), Box- Jenkins ARIMA(p,d,q) and Random Walk with drift models to get the best fit to the trend of the data. The order of the time series models have been calculated by studying the ACF, PACF plots and the coefficients have been derived using the Yule-Walker equation matrix. An in-sample forecast of the years 2014-17 are taken. The Mean Squared Error (MSE) and the Mean Absolute Percentage Error (MAPE) as a measure of accuracy is used to determine the best fit model. ARIMA(3,1,1) produced lower values making it the best-fit model. Out-of-sample forecasting was done for 2018-2025. The forecast value shows that at the current trend, India would have 0.03 deaths per 1000 population in the 5-14 age group in 2025 showing that the government’s policies and health care interventions towards realization of the MDG4 goal is working positively.
SETTING THE “RIGHT” GOAL: POST M&A INNOVATION PERFORMANCE AND GOAL ORIENTATION
Authors: Doan Trang Thu
Published: September 2020

Pharmaceutical firms spend billions of dollars to develop the next breakthrough drug and to maintain their market shares. We investigate how pharmaceutical firms use mergers and acquisitions to boost their innovation performance which has been found to result in better performance outcomes. Adding to the recent research on mergers and acquisitions, we found that firms that are explicit with their R&D goal orientation from the beginning of the acquisition journey are more successful in their innovation endeavours than firms with other goal orientation. Further, the firms’ prior acquisition experience appears to aid their innovation performance. However, we found that target size can affect the post-acquisition innovation performance but has diminishing returns as target size increases. Ultimately, our findings suggest that having an explicit R&D goal orientation is really important for a healthy innovation pipeline for pharmaceutical firms.

Determinación de orientaciones de ciudades romanas por medio de la varatio
Authors: Orfila Pons Margarita , Rodríguez-Antón Andrea , Chávez-Álvarez Esther , González-García Antonio César , Sánchez López Elena H. , Belmonte Juan Antonio
Published: September 2020

En el presente artículo se aborda la tan debatida cuestión de las orientaciones de ciudades romanas combinando dos procedimientos: un análisis estadístico de las orientaciones de una muestra significativa de ciudades romanas en la península ibérica, y los resultados de una investigación basada en la experimentación y reconstrucción de instrumental de agrimensura romana. En concreto, se busca reforzar, o rechazar, la hipótesis del empleo de la varatio para la orientación en el terreno, y su posible modo de ejecución: método basado en la aplicación de triángulos rectángulos con catetos en proporción de números naturales. Se postula además la línea meridiana como la generadora de cada nuevo proyecto, incluyéndose un posible procedimiento para su obtención a partir de los preceptos de Vitruvio (De Architectura VI, I). Los resultados del análisis estadístico devuelven una distribución de las orientaciones no aleatoria y que, en muchos casos, está en buen acuerdo con los valores predichos de la aplicación de la técnica de la varatio en sus diferentes variantes. Con esto se pretende determinar si sería factible el empleo de una técnica estandarizada para trazar los patrones de orientación obtenidos.
Parcelaciones funerarias en necrópolis cordubenses. Reflexiones a partir de dos hallazgos recientes
Authors: Vaquerizo Gil Desiderio
Published: September 2020

Este trabajo ofrece una aproximación al paisaje de las áreas funerarias cordubenses de época altoimperial, sometidas a los vaivenes propios de una ciudad viva, en expansión y contracción alternas según las épocas, y objeto más que posible de especulación supuesto el sacrificio que representaba dedicar terrenos suburbanos de enorme potencial económico a fines funerarios y el alto precio consecuente de los loci. Creemos, de hecho, haber detectado ejemplos claros de lotizaciones bien planificadas en forma de recintos y acotados reforzados de forma ocasional mediante el uso de mensurae sepulcri, que analizamos a través de dos sepulcreta especialmente significativos excavados hace solo unos años.
Identidad y muerte en las necrópolis gaditanas a partir de la biografía de sus monumentos funerarios. El caso de Lucius Popillius Acastus
Authors: De Balbín-Bueno Ricardo
Published: September 2020

La identidad en el mundo antiguo es objeto de discusión a partir de parámetros diferentes, pero indudablemente las manifestaciones mortuorias aportan referencias de gran interés. El estudio del hallazgo y características de un monumento funerario singular de las necrópolis de Cádiz sirve para valorar la complejidad social del mundo de la muerte. En el caso que nos ocupa, tanto el propio monumento, como su ubicación, contexto y epígrafe, abundan en la conexión entre identidad y determinados usos funerarios que se arraigan en tradiciones ligadas a topografías funerarias específicas y culturas concretas. El contexto arqueológico, el uso de piedra local, el recubrimiento de emulación marmórea, posible uso de colorante en la placa o el tamaño y visibilidad de la pieza la singularizan en el contexto gaditano y peninsular. Una de las líneas de trabajo que se derivan de este análisis es cómo la presencia de etnias e identidades diversas llegó a determinar el mundo de la muerte tan marcadamente. Este aspecto reaviva los argumentos de reflexión sobre la representatividad de colonos, indígenas o extranjeros en la ciudad de Gades en la antigüedad.
Tecnología hidráulica y construcción de presas en Melque: estratigrafía, tipología, paisaje y proceso de obra
Authors: Barahona Oviedo Marisa
Published: September 2020

Se presenta una síntesis de los estudios realizados en el conjunto de presas del yacimiento de Melque (San Martín de Montalbán, Toledo). Su análisis se hacía necesario por la singularidad de estas construcciones y para ahondar en la explicación integral del complejo económico-productivo vinculado al monasterio mozárabe, ya conocido. El procedimiento metodológico seguido, específico y novedoso, combinó las herramientas estratigráfica y tipológica, propias de la Arqueología, con la revisión geomorfológica e hidrogeológica del entorno, documentando con detalle las presas del Sitio Histórico de Melque, a la vez que se profundiza en las dinámicas del paisaje histórico en el que se insertan. Esta múltiple estrategia ha permitido confirmar una cronología altomedieval para el conjunto de presas y vincula la construcción de las dos superiores de cada arroyo con la primera fase del asentamiento monástico mozárabe en la segunda mitad del siglo VIII.

Published: September 2020

Big data refers to the massive amount of data from sundry sources (gregarious media, healthcare, different sensor, etc.) with very high velocity. Due to expeditious growth, the multimedia or image data has rapidly incremented due to the expansion of convivial networking, surveillance cameras, satellite images, and medical images. Healthcare is the most promising area where big data can be applied to make a vicissitude in human life. The process for analyzing the intricate data is mundanely concerned with the disclosing of hidden patterns. In healthcare fields capturing the visual context of any medical images, extraction is a well introduced word in digital image processing. The motive of this research is to present a detailed overview of big data in healthcare and processing of non-invasive medical images with the avail of feature extraction techniques such as region growing segmentation, GLCM, and discrete wavelet transform.

Distributed denial of service (DDoS) attacks have become a serious danger against the availability of services in cloud computing environment. Current defending mechanisms cannot detect DDoS attacks with high accuracy. This is mainly due to the fact that the unrealistic value of the studied variables was used. In view of this problem, the authors propose a novel approach called confidence interval-based filtering (CIF) to detect DDoS attacks. The proposed approach is implemented using VMware and JAVA applications. The simulation results showed that CIF outperforms the existing approaches in terms of detection rate and false negative and positive rates with an acceptable computation time.

A utilização de pastagens na alimentação de rebanhos pode constituir em uma forma de economia para o produtor. Contudo, em áreas semiáridas a utilização desse recurso pode ser limitada, principalmente em regiões onde a utilização de irrigação é inviável. Nessas regiões cuidados especiais devem ser dados ao solo, já que em momentos de estiagem a redução da cobertura do solo pode elevar a taxa de erosão. A produção de produtos de origem animal para as populações alocadas em regiões semiáridas é abalada de forma mais marcante pelos períodos de estiagem mais extensos, não só quanto a disponibilidade de alimento, bem como a redução da qualidade nutricional da pastagem. Dessa forma, em momentos de carecimento de chuva em áreas semiáridas, alterações no manejo das pastagens e dos animais podem ser realizadas para promover melhores desempenhos produtivos dos rebanhos. Para obtenção de maior produção vegetal, a irrigação se faz necessária, principalmente quando se pensa em intensificação da produção animal a pasto. Embora, em algumas regiões do mundo, este recurso seja inviável. Sendo assim, é necessária exploração dos recursos disponíveis, como conservação de forragens, utilização de palma forrageira e utilização de coprodutos agroindustriais, que permitam viabilizar a atividade pecuária.

No ensino técnico, é essencial haver a integração dos conhecimentos teóricos e práticos para a formação de um bom profissional, cabendo ao professor buscar maneiras de integrar esses dois aspectos durante as aulas. A proposta deste trabalho foi verificar o nível de participação e envolvimento dos alunos durante o ensino de um conteúdo da disciplina de Metrologia ao associar o conteúdo teórico a uma aula prática em laboratório com a possibilidade de manuseio do objeto de estudo, como recurso didático-pedagógico, em comparação com uma aula teórica tradicional. Como resultado, foi possível observar que a utilização do recurso didático gerou maior participação, entendimento e motivação nos alunos durante o processo de ensino-aprendizagem em comparação com o ensino tradicional. Desse modo, considera-se que apresentar a teoria associada à prática é um caminho que pode apresentar resultados muito bons, se bem planejado e executado de forma sistemática.

Introdução: O aumento da expectativa de vida e consequente envelhecimento populacional é um grande desafio para o setor da saúde. Diante deste contexto espera-se identificar as vulnerabilidades do processo de assistência para readequação das intervenções e garantir a excelência no cuidado ao idoso. Objetivo:avaliar a implementação de medidas de prevenção da pneumonia em idosos hospitalizados.Método: estudo transversal.A coleta de dados ocorreu em um hospital público terciário, por meio de análise de prontuários e entrevista com idosos ou acompanhantes. A análise dos dados foi realizada por meio de programa estatístico Epi Info.3.54 Estudo aprovado pelo Comitê de Ética CAAE 394013144.0000.5231. Foram avaliados os cuidados para prevenção de pneumonia em 142 idosos. Resultado: constou-se que os cuidados foram prescritos na maioria das vezes, sendo que a maior diferença foi encontrada em relação à checagem e confirmação da realização do cuidado. O cuidado de cabeceira elevada foi checado por 92,9% dos profissionais e foi confirmada sua realização por 85% dos idosos. Em relação ao cuidado de higiene oral também foi encontrada uma diferença em relação à checagem, que foi de 98,5%, e sua confirmação da realização 83,8%. Conclusão: há necessidade de zelar e garantir a implementação das ações prescritas e da sua checagem para o desenvolvimento seguro e eficaz do plano de cuidado, pois, muitas vezes o cuidado prescrito é checado, mas sua realização não é confirmada na mesma porcentagem pelo usuário, o que traz à tona uma discussão importante sobre a qualidade do atendimento prestado ao idoso hospitalizado.

Published: September 2020

Objetivo: identificar o conhecimento de pacientes oncológicos em tratamento quimioterápico ambulatorial sobre os sinais e sintomas de emergência. Métodos: Estudo descritivo, qualitativo. Utilizaram-se dois instrumentos: um questionário de caracterização dos participantes e uma entrevista aberta. A análise do primeiro instrumento foi por estatística descritiva simples; o segundo por análise temática. Resultados: Os sintomas descritos pelos participantes foram: febre, náuseas, vômitos, constipação, incapacidade/dificuldade de ingestão alimentar, cefaleia, dor generalizada ou dor nos locais que remetem ao tumor, dispneia, vertigem, perda de consciência, perda da capacidade de andar, dor no peito e variações bruscas de nível de pressão sistêmica (aumento ou diminuição).Como condições que podem interferir na decisão da busca pelo serviço de emergência, foi identificada a manifestação de sintomas anormais para o paciente, o conhecimento do paciente sobre a patologia e tratamento, além da experiência prévia do paciente com o serviço de emergência. Conclusão: Em suma, os motivos que levam o paciente oncológico a buscar a emergência estão ligados à “gravidade” que o mesmo atribui aos efeitos do tratamento.

Objetivo: Descrever os tipos de atendimentos pré-hospitalares dejovens, realizados por um Grupamento do Corpo de Bombeiro, e compará-los segundo as características das vítimas e das ocorrências. Método: Estudo transversal, retrospectivo, descritivo e analítico, com abordagem quantitativa, composto por 198 ocorrências atendidas, em 2015, no Distrito Federal. Os dados foram coletados a partir das fichas de atendimentos do serviço. Para comparação proposta, aplicou-se o teste qui-quadrado e a razão de verossimilhança, adotando-se p<0,05. Resultados: A maioria dos atendidos era do sexo masculino (54,0%) e idade superior a 18 anos (86,4%). Predominaram-se os atendimentos com tempo de resposta menor que 10 minutos (83,8%) e gravidade classificada estável (98,0%). O resultado da comparação foi significativo para a categoria trauma quanto às características de idade, sexo, local de ocorrência e regional de destino, todas com p≤0,0001. Conclusão: A população jovem estudada, com ênfase ao sexo masculino, é vulnerável a ocorrências traumáticas, especificamente aos atendimentos ocorridos em via pública. Os dados expostos apontam para a necessidade de educação em saúde e ações intersetoriais que promovam a prevenção dessas ocorrências na população jovem.
