(CPS)  Hoje em dia não se pode falar em medicina esportiva sem falar em ressonância magnética, especialmente no diagnóstico das lesões das articulações. O joelho, por exemplo, é uma das articulações que mais preocupam preparadores físicos e esportistas, pois os afastamentos por lesões costumam tirar os atletas de circulação por vários meses. O joelho constitui uma das maiores e mais complexas articulações do corpo humano, pois é formado por ossos, tendões, cartilagens, meniscos e ligamentos que permitem a movimentação, a estabilidade e a resistência para suportar, aproximadamente, 70% do total da massa corporal.

Assim, baseado no exame de ressonância magnética do joelho de um atleta, que apresentava perfeitas condições nessa articulação, um médico fez os esquemas A e B, conforme a figura.

Sobre os componentes estruturais dos esquemas A e B, assinale a alternativa correta

 Uma empresa precisa comprar uma tampa para o seu reservatório, que tem a forma de um tronco de cone circular reto, conforme mostrado na figura.

Considere que a base do reservatório tenha raio r e que sua lateral faça um ângulo de 60° com o solo.

 Se a altura do reservatório é 12 m, a tampa a ser comprada deverá cobrir uma área de :

(UFPA) The Impact of Media Violence on Children and Adolescents: Opportunities for Clinical Interventions

Over the past 30 years there has been extensive research on the relationship between televised violence and violent behavior among youth. Longitudinal, cross-sectional, and experimental studies have all confirmed this correlation. Televised violence and the presence of television in American households have increased steadily over the years. Studies reveal that children watch approximately 28 hours of television a week, more time than they spend in school. The typical American child will view more than 200,000 acts of violence, including more than 16,000 murders before age 18. Television programs display 812 violent acts per hour; children's programming, particularly cartoons, displays up to 20 violent acts hourly.

How does televised violence result in aggressive behavior? Some researchers have demonstrated that very young children will imitate aggressive acts on TV in their play with peers. Before age 4, children are unable to distinguish between fact and fantasy and may view violence as an ordinary occurrence. In general, violence on television and in movies often conveys a model of conflict resolution. It is efficient, frequent, and inconsequential. Heroes are violent, and, as such, are rewarded for their behavior. 1They become role models for youth. The typical scenario of using violence for a righteous cause may translate in daily life into a justification for using violence to retaliate against perceived victimizers. Hence, vulnerable youth who have been victimized may be tempted to use violent means to solve problems. Unfortunately, there are few, if any, models of nonviolent conflict resolution in the media. Additionally, children who watch televised violence are desensitized to it. They may come to see violence as a fact of life and, over time, lose their ability to empathize with both the victim and the victimizer.

Child and adolescent psychiatrists, pediatricians and other physicians can have a major impact on the effects of media violence. The American Academy of Pediatrics (AAP) has created a list of recommendations to address television violence. It suggests that physicians talk openly with parents about the nature and extent of viewing patterns in their homes. Parents should limit television to 1-2 hours daily and watch programs with their children, enabling them to address any objectionable material seen.

Physicians should make parents and schools "media literate," meaning they should understand the risks of exposure to violence and teach children how to interpret what they see on television and in the movies, including the intent and content of commercials. In doing so, children may be increasingly able to discern which media messages are suitable. Schools and homes should teach children conflict resolution.

Physicians, in their role as health promoters, should become more active in educating the media to become more sensitive to the impact of violence on youth. The arena of media violence is a new frontier where physicians can promote health through public education and advocacy.

Leia o poema abaixo:

Pensem nas crianças

Mudas telepáticas

Pensem nas meninas

Cegas inexatas

Pensem nas mulheres

Rotas alteradas

Pensem nas feridas

Como rosas cálidas

Mas oh não se esqueçam

Da rosa da rosa

[...]

A rosa hereditária

A rosa radioativa

Estúpida e inválida

A rosa com cirrose

Sem cor sem perfume

Sem rosa sem nada.
