Ergonomic Design in the Wearable Medical Devices Sphere
A Tampa, Florida, high school teacher, Steven A. Field, MD, offers students an engaging approach to the sciences. Among Florida educator Steven A. Field, MD’s areas of experience is human ergonomic research, and he has held appointments with corporate ergonomic committees and presented at national industry conferences.
As featured in Medical Plastic News, the focus of many niche companies such as i4 Product Design is on creating ergonomic products that increase the ease of human interaction. A major thrust by CAD designers is on making equipment in a hospital setting wearable, with a particular focus on utilizing specific areas on the head of the user.
Subjective measures such as “a comfortable fit” come to the fore in such design, with subtle differences tested on human wearers prior to decisions on whether to incorporate features such as slide and pivot capacities and modular parts.
An example of medical device design projects that resulted in diverging ergonomic routes are a pair of i4 -designed Optos desktop retinal scanning devices, the California and the Daytona. The user interface for the California model, which is employed by ophthalmologists in patient evaluations of up to 20 minutes, is distinct from the Daytona scanner, which is used on patients for less than a second.
A particular requirement was that the California model provide stabilization for the head and allow adjustability in both the scanner head and direct patient interface in ways that accommodate a wide range of users.

The Chemistry Foundations of Biology

Based in Tampa, Florida, Steven A. Field, MD teaches a number of courses, from Marine Science to Anatomy and Physiology, with the Hillsborough County School District. Among the courses Steven A. Field, MD teaches is Honors Biology. At the foundation of biology is chemistry, with all organic compounds composed of carbon.
Containing six neutrons and six protons, carbon is relatively compact and takes on a variety of chemical forms, including rings, sheets, spirals, double bonds, and triple bonds. Carbon atoms also have six electrons, and need for extra electrons, which ensures that they bond with other carbon molecules, as well as multiple other molecules such as nitrogen, hydrogen, oxygen, and phosphorus.
With an infinite number of combinations possible, this has enabled the development of complicated structures made possible on the Earth by carbon dioxide, which floats throughout the atmosphere. Simple carbon compounds include methane, which involves one carbon molecule and four hydrogen electrons inhabiting the outer electron shell. This is represented in chemistry by dot structure diagrams.

Pickleball - An Obscure Game Popularized in the US and Canada
Florida-based Hillsborough Community College biotechnology instructor Steven A. Field, MD brings more than 30 years of experience in the science field to his position. Beyond his activities in the science community, Steven A. Field MD enjoys playing a game known as pickleball.
Pickleball is a paddle sport that combines elements from tennis, ping-pong, and badminton. Played on a badminton-sized court, the sport utilizes a modified tennis court and requires players to hit a holed-plastic ball with paddles. The game uses simple rules in order to encourage participation from players of all ages, such as requiring the ball to ounce once before players can hit it and setting the net lower than in other paddle games. Teams take turn serving like in tennis, although teams can only earn points during their serve. Games are played as doubles or singles and continue until one team reaches 11 points.
Creators Joel Pritchard, Barney McCallum, and Bill Bell developed Pickleball in the 1960s during a short ferry ride from Seattle, Washington, with the intent of entertaining their children, who had grown bored of their usual summertime activities. Misconception over the origin of the game’s name remains widespread and rumors suggest the Pritchards named the game after the family dog. However, the family asserts that the dog was named after the game and the true inspiration came from their maritime pursuits.

Joseph P. Kennedy Foundation Fellowship Urges Disabled Advocacy
Florida resident Steven A. Field, MD, is currently a health sciences teacher with the Hillsborough County, Tampa school district. A graduate of the University of South Florida and the MD program at Hahnemann Medical College, Steven A. Field is also a recipient of the Joseph P. Kennedy, Jr. Foundation Fellowship.
Founded in 1946, the Joseph P. Kennedy, Jr. Foundation is a charitable organization that advocates for the rights of persons with intellectual disabilities. The Foundation implemented the Public Policy Fellowship Program in 1980 to support this goal. The one-year program in Washington, D.C. is designed to prepare individuals for leadership roles in public policy by providing experience in public administration. It also familiarizes fellows with the work of the disability community and requires that fellows demonstrate experience in one of several areas -
1.Advocacy to improve the lives of individuals with intellectual or developmental disabilities
2.Efforts to improve community services for disabled individuals in any service area, ranging from health care and employment to education and housing
3.Development, implementation, or support of training programs designed for disabled individuals or those around them
4.Engagement in efforts to empower disabled individuals, related to either their own life choices or to influencing public policy at the national or state levels
