Virtual reality techniques, involving three-dimensional imaging and surround sound, are increasingly being used in diagnosis, treatment, and medical education. Initial applications of virtual reality in medicine involved visualization of the complex data sets generated by computed tomography (CT) and magnetic resonance imaging (MRI) scans. A recent application of these techniques for diagnostic purposes has been the “virtual colonoscopy,” in which data from a contrast-enhanced abdominal CT scan is used to make a “fly-through” of the colon. Radiologists then use this fly-through for colon cancer screening. Recent improvements in methodology have brought the sensitivity and specificity of this technique closer to the levels of optical colonoscopy, and patients prefer the technique to the traditional method.

Virtual reality has also been used extensively to treat phobias (such as a fear of heights, flying and spiders) and post-traumatic stress disorder. This type of therapy has been shown to be effective in the academic setting, and several commercial entities now offer it to patients. In one of my projects using the multi-user virtual reality environment offered by Second Life, one of several easily available online virtual reality environments, we have used a virtual psychosis environment to teach medical students about the auditory and visual hallucinations suffered by patients with schizophrenia.

Virtual reality has been used to provide medical education about healthcare responses to emergencies such as earthquakes, plane crashes and fires. While the primary advantage in phobia treatment is a “safe environment” which patients can explore, the primary advantage in emergency preparedness is simulation of events that are either too rare or too dangerous for effective real-world training. The immersive nature of the virtual reality experience helps to recreate the sense of urgency or panic associated with these events.

Virtual reality programs have also been used for a variety of medical emergency, mass casualty, and disaster response training sessions for medical and public health professionals. One study developed a protocol for training physicians to treat victims of chemical-origin mass casualties as well as victims of biological agents using simulated patients. Although it was found that using standardized patients for such training was more realistic, the computer-based simulations afforded a number of advantages over the live training. These included increased cost effectiveness, the opportunity to conduct the same training sessions over and over to improve skills, and the ability to use “just-in-time” learning techniques and experience the training session at any time and location, while adjusting the type and level of expertise required to use the training for various emergency response professionals. Others have explored the potential for training emergency responders for major health emergencies using virtual reality. Their objective was to increase exposure to life-like emergency situations to improve decision-making and performance and reduce psychological distress in a real health emergency.

Experience with recent natural disasters and terrorist acts has shown that good communication and coordination between responders is vital to an effective response. In my work using Second Life to develop a virtual mass disaster emergency clinic to hand out antibiotics to the population following a massive anthrax bioterrorism attack, we have found a number of important advantages of the virtual world, over the real world, for training first responders.

Responders to such events come from many different organizations, including fire, police, military, and hospital personnel. There are three major difficulties in training and evaluating these first responders in the real world:
1. They have little or no chance to train together before the event occurs and hence lack teamwork skills.
2. What training they may have had comes at great cost, in large part due to the effort and need to transport so many people to a specific training site at a specific time.
3. The training sites frequently cannot be the most common targets – for example, one cannot shut down the Golden Gate Bridge during rush hour to train for an earthquake or terror scenario.

Virtual reality offers some intriguing advantages over the real world for these aspects of first responder training, as all of the above difficulties can be overcome. Virtual reality systems can support multiple simultaneous users, each connecting to the system using standard office personal computers and broadband Internet access. Lifelike models of buildings, roads, bridges, and other natural and man-made structures where the users can interact can be constructed. Finally, the whole scenario can be digitally preserved and a full workflow analysis can be performed retrospectively. Public health officials and first-responders can work through the scenarios as many times as they like to familiarize themselves with the workflow and emergency protocols, without encumbering the time and expense of organizing a mock emergency in real life.

Virtual Reality treatments are rapidly becoming more available. They are currently being used to treat post-traumatic stress disorders caused by wartime experiences, and US servicemen are now increasingly being offered such programs. Rather than the traditional method of confronting old nightmares, online technology is able to deliver treatment in a far more therapeutic and humane way. Patients are “transported” to the battlefront and fears and traumas are resolved in virtual place and real time. Virtual Reality is here to stay, and will increasingly be used widely in a number of areas of healthcare.

There no wonder if you are seeing two year old using ipads, what you can do is have your kids utilize the benefit of such technology with educational videos for kids available by many websites. It’s important for a parent to be careful as getting wrong content can harm your kids.

Presently, projects are associating children in internet learning groups, following kids’ advancement through lessons and diversions, and altering each understudies’ experience. Thus, before you press the off catch, consider these eleven ways that you can augment your youngster’s innovation time at home and at school.

Learning with Technology at Home

Whether you’re passing back your touch-screen telephone to your kid, or your babies’ favored recess is at the machine, here are eight approaches to verify your youngster’s encounters with engineering are instructive and fun.

Concentrate on Active Engagement Any time your kid is locked in with a screen, says Shelley Pasnik, chief of the Center for Children and Technology, make inquiries. Stop a project, or quiet the advertisements, and ask captivating inquiries. What was that character considering? Why did Clifford do that? What would you have done in that circumstance?

Consider Repetition Dvds and YouTube features include a crucial element for youthful personalities and also a great source for educational videos for kids. Permit your young tyke to watch the same feature again and again, and ask him what he perceived after each one survey.

Make it Tactile Unlike machines that oblige a mouse to control questions on the screen, new tablet machines permit children control “physical” objects with their fingers.

Polish Problem Solving A rising class of amusements will constrain your youngster to take care of issues as he plays, building fixation and investigative aptitudes simultaneously. Berger suggests amusements that children need to evaluate, for example, Max and the Magic Marker or Crayon Physics. On the off chance that your youngster is trapped, urge him to discover better approaches to approach the problem. You can also get educational videos for kids on various subjects that not only cover the basics of their subjects but also help kids learn about various world, animals facts.

Empower Creation Use engineering for creation, not simply diversion. “Children have so few chances to express their will or settle on decisions,” says Pasnik. Let your kid record a story on your ipod, or sing a tune into your feature diversion framework. At that point, make a completely new sound utilizing the playback choices, ease off and accelerate her voice and include diverse foundations and beats until she’s made something particularly her.

Demonstrate to Him Generally accepted methods to Use It Many machine amusements have diverse levels and youthful youngsters may not know how to climb or change levels. In the event that your kid is stuck on one level that is gotten to be excessively simple, inquire as to whether he knows how to climb and help him in the event that he needs to a greater degree a test.

Finding ways to attract and retain new students is one of the core focuses of Enrollment Management divisions of colleges and universities, and Enrollment Management [] Consultants alike. Increasingly, college admissions officers are turning to technology in order to accomplish the task of attracting and retaining prospective students.

In the news, we’ve seen recent headlines that focus on Enrollment Management topics such as: the recent trend in State funding of higher education; the promotion of distance learning initiatives; performance based funding policies; and how colleges and universities seek to bolster socio-economic diversity among students, by promoting different admissions procedures.

We’ve also seen how the correct use of direct response marketing (a form of marketing that allows advertisers to quantify marketing ROI by soliciting a direct response from the consumer)–combined with sophisticated tracking technologies, and academic advising centers–provides more applications and enrollments. More colleges and Universities are turning to the internet, and other mediums that provide the opportunity for the increased efficiency of direct response marketing.

In an article entitled “Admissions deans grapple with the promises and pitfalls of electronic recruiting” Elizabeth Farrell discusses the new methods that universities are using to reach out to prospective students. A quote that appears in the article from the director of admissions of Colby, is a good summary:

“We’re really trying to keep up with what’s going on in the commercial world, because that’s what the kids are exposed to,” says Steve Thomas, director of admissions at Colby. “It’s what they’ve come to expect in dealing with us.”

As colleges and universities delve into advertising and marketing, they may not realize the enormous amount of time and money that can be saved by outsourcing Enrollment Marketing initiatives to Direct Response Marketing companies that are more equipped to reach target students, on a performance basis. This shouldn’t come as a surprise, as marketing agencies have been utilizing the internet and other channels in order to initiate direct quantifiable contact with consumers for some time now.

Promoting Diversity

An interesting article appeared in the New York Times today that focuses on promoting ethnic diversity in student bodies through scholarships and admissions procedures. Michael F. Summers is runs a biochemistry laboratory at the University of Maryland, Baltimore County. The article highlights the steps that Summers has taken in order to increase the number of African Americans that have access to an educational structure that will provide them with the opportunity to pursue doctoral degrees.

Summers has taken steps like creating the Meyerhoff Scholarship program, a full scholarship that is awarded to African Americans. This program has provided the opportunity to enter a competitive scientific program to about 800 undergraduates.

In addition to highlighting the aggressive position that Summers has taken, the article also highlights many statistics that show just how few African Americans are awarded PH.D’s in science, math, and engineering: less than 3%. TO address this, Summers created the Meyerhoff Scholarship, a program that starts with an aggressive admission criteria:

We take minority students — those with very high SATs and high school grades — and we offer them full scholarships. We compete for them with the Ivy Leagues and we focus on retaining them as science majors. We provide the same kind of nurturance they might get at the traditionally black colleges, but we do some extra things, too. In the summer between high school and college , we have a “bridge program” showing the students what it will take to excel in science. We say, “we expect you to get A’s,” and we show them how to study so they’ll get them.”

By securing a scholarship program that funds high-achieving economically underprivileged African Americans, Summers has evened-out the diversity of his lab: 15 of 32 researchers are African American, a proportion that is unheard of in a biochemistry lab.

The different approaches that colleges and universities are taking to generating student enrollments is very interesting, and we will continue to monitor the new ways that academic institutions seek to increase diversity, and increase applications and enrollments.
