How to get started learning about medicine online

Online medical courses are designed to enable students to gain medical knowledge from a distance. Knowledge in various fields in medicine like nursing, EMT, etc., can be acquired through these medical courses. Online medical courses may be general, like anatomy and physiology, ir specific like those dealing with healthcare informatics, patient transportation, and so on. 

Let us take a look at some of these courses. 

General Human Anatomy Course: The course provides the students with a brief introduction to human anatomy. The various systems like muscular, reproductive, nervous, etc., their interactions, form the core curriculum. 

Medical Terminology Course: This course familiarizes students with the basic terminology of medicine. Terminology relating to drugs, medical treatments, scholarly and general programs are taught in these courses. 

Emergency Medical Technician (EMT Course): The course makes the students proficient to begin working as EMTs. It also prepares students for pursuing paramedical courses. The online course makes use of interactive teaching methods, computer assignments, and electronic textbooks, for teaching. 

Medical Physiology Course: The course teaches students everything about human physiology. It is inclusive of study on various human organ systems. It covers homeostasis, cellular chemistry, signaling mechanisms, etc. 

Various institutes in India and around the world offer e-learning medicine courses. One of them includes Medvarsity. It offers more than 140 courses for nurses, doctors, and general medical enthusiasts. It offers courses like a masterclass in medical emergencies online. The masterclass is a course designed to help doctors working or aiming to work at Emergency departments in hospitals. Medvarsity works in collaboration with various medical institutions in India and abroad. 

John Hopkins is another university that offers online health courses. They include a series of undergraduate and graduate classes. The classes cover issues in public health, the various changes in the delivery of health care, and different ethical challenges. Some of their courses are Introduction to Health Policy, Ethical issues in Public Health, Managed Care and Health Insurance, Population Change and Public Health, etc.

Online medical courses are also available at the Massachusetts Institute of Technology. The institute offers an undergraduate class called Comparative Health Policy. The course analyses the system of healthcare in the United States, its successes, challenges, and prospects. It offers a comparative study of other countries’ health systems with America. It includes the study of the problems that affect health care delivery. The students can download the lecture notes as a part of the class. 

Online medical courses ensure that those who cannot study medicine in the traditional way can study in this way.

A step-by-step guide to 3D modeling for explainer videos

Are you looking to create explainer videos that will help take your product idea to your customers? Would you like to demonstrate why your potential customers must choose you over other competitors, in a succinct, yet compelling way? 

Add the magic of 3D animation to create to make your business ideas come alive and tell the stories themselves. Create captivating and visually appealing explainer videos that will unravel your business ideas and grab the attention of the viewer. 

So, how does this magic happen? What are the steps involved? Read on to know more.

The art of creating animations can be broadly categorized into 3 main stages: pre-production, production, and post-production. The concept of your explainer video is planned and developed in the pre-production stage. The actual animation happens in the production phase. The third and the final stage in creating an explainer video, is the post-production. Post-production involves rendering the animation frames, editing the pieces of animation, adding the soundtrack and compositing the animation.

With this in mind, let us understand the steps involved, in detail,  in creating animations using 3D models.

Step 1: Script and storyboards (Pre-production)

The first step in creating an explainer video is conceptualizing your ideas in the form of a story, called a script. You then visualize the script in the form of a storyboard. The storyboard is a screen-by-screen sketch of your story.

Step 2: Building a 3D model (Production) 

Your storyboard gets transformed into a 3D model in this step. Characters, environment and props are modeled in this step. While creating an explainer video, simple models are used in order to keep the file size manageable. 

Step 3: Texturing (Production)

Texturing is adding colors, material, dirt and even 2D images on the 3D model to enhance the look, feel and design of the model. Again, in an explainer video, basic texturing is applied.

Step 4: Rigging (Production)

For a 3D model to act and emote, it needs to be animated. To achieve this, animators create 3D skeletons and attach them to the 3D models. This process is called rigging.  

Step 5:  Lighting (Production)

Lighting sets the look and tone of the scene. A single directional light or the default light available are usually used in the explainer videos. 

Step 6:  Animation (Production) 

The puppet is now ready to come alive! The animation is all about giving life to a 3D model. While creating an explainer video, simple machine animations are used.

Step 7:  Rendering of the animation (Post-production) 

Next comes rendering of the animation created in an image sequence. It is important, but a time-consuming step in an animation production pipeline. 

Step 8:  Compositing (Post-production)

Compositing involves adding special effects and editing the raw renders to include other required components of the video including on screen text.. Everything from color correction to adding depth of field is done in this stage. 

Step 9: Music and voice over

No animation is complete without audio. Before exporting the video, soundtrack and voiceover are added. 

Step 10: Editing and final video output

Your explainer video is now almost ready. The renders and audio are edited and checked to ensure synchronization. The composited renders, music and foley are compiled and edited to ensure that everything is in synchronization. The video is then exported into a format that is suitable for broadcasting. 

So, this is how you can create animations for explainer videos using 3D modeling irrespective of the software that you choose to use. 

That’s all folks!

Aerial Robotics Beyond Drones: Interview with Bob Dahlstrom

We tend to think of drones as the only kinds of aerial robots, but Apellix has developed an aerial robot that can be used to deliver products instead of simply sensing or collecting images. Welcome to an interview with Bob Dahlstrom, CEO and founder of Apellix, a dynamic, new aerial robotics company.

1.  What is your name and your relation to innovation and robotics? 
Bob Dahlstrom – Growing up working at my parents’ hardware store from age 12 to my early 20’s provided me hands-on experience with the practical needs of people to fix, repair, or replace a wide variety of items – often with innovative mechanical solutions. Later, in the mid-80s while working in a “clean room” at an integrated circuit manufacturer and writing software code for the first time, I made the connection that the world was destined to have software interact with and instruct hardware, as we moved from physical and electrical mechanical systems to software-controlled systems.
