BackgroundSimulators used in teaching are interactive applications comprising a mathematical model of the system under study and a graphical user interface (GUI) that allows the user to control the model inputs and visualize the model results in an intuitive and educational way. Well-designed simulators promote active learning, enhance problem-solving skills, and encourage collaboration and small group discussion. However, creating simulators for teaching purposes is a challenging process that requires many contributors including educators, modelers, graphic designers, and programmers. The availability of a toolchain of user-friendly software tools for building simulators can facilitate this complex task.ObjectiveThis paper aimed to describe an open-source software toolchain termed Bodylight.js that facilitates the creation of browser-based client-side simulators for teaching purposes, which are platform independent, do not require any installation, and can work offline. The toolchain interconnects state-of-the-art modeling tools with current Web technologies and is designed to be resilient to future changes in the software ecosystem.MethodsWe used several open-source Web technologies, namely, WebAssembly and JavaScript, combined with the power of the Modelica modeling language and deployed them on the internet with interactive animations built using Adobe Animate.ResultsModels are implemented in the Modelica language using either OpenModelica or Dassault Systèmes Dymola and exported to a standardized Functional Mock-up Unit (FMU) to ensure future compatibility. The C code from the FMU is further compiled to WebAssembly using Emscripten. Industry-standard Adobe Animate is used to create interactive animations. A new tool called Bodylight.js Composer was developed for the toolchain that enables one to create the final simulator by composing the GUI using animations, plots, and control elements in a drag-and-drop style and binding them to the model variables. The resulting simulators are stand-alone HyperText Markup Language files including JavaScript and WebAssembly. Several simulators for physiology education were created using the Bodylight.js toolchain and have been received with general acclaim by teachers and students alike, thus validating our approach. The Nephron, Circulation, and Pressure-Volume Loop simulators are presented in this paper. Bodylight.js is licensed under General Public License 3.0 and is free for anyone to use.ConclusionsBodylight.js enables us to effectively develop teaching simulators. Armed with this technology, we intend to focus on the development of new simulators and interactive textbooks for medical education. Bodylight.js usage is not limited to developing simulators for medical education and can facilitate the development of simulators for teaching complex topics in a variety of different fields.

“…Collectively, the glomerular capsule and accompanying glomeruli are called renal corpuscles. [6] The endothelium of the glomerular capillaries is perforated by many pores, thus making it a multi-pore. It allows large amounts of solutes, especially protein-free fluids, to pass from the blood into the glomerular capsule.…”

Hemodialysis is an act to partially replace kidney function and dispose of substances (water, urea, creatinine, potassium, magnesium, etc.) that are not needed in the blood. Typically, 70% - 90% of hemodialysis patients have recently had high blood pressure (hypertension) during the first hemodialysis. After passing through the first month of hemodialysis (extracellular volume downhill), blood pressure decreased progressively, reaching a normal level of variable proportion (30% - 95%) in patients who are already been doing hemodialysis for a few months. Mean Arterial Pressure predialysis patients with a high initial decline in the first-week dialysis, then Mean Arterial Pressure settled and stable enough after three months of hemodialysis. This study aims to prove that there is an improvement in blood pressure after hemodialysis for patients with Chronic Kidney Disease at Universitas Kristen Indonesia Hospital. The methodology used is the analytic ex post facto with data collected retrospectively from the Archives of Medical Record Universitas Kristen Indonesia Hospital Inpatient and use quota-type sampling. The table above shows that of 52 patients with Chronic Kidney Disease Stage V undergoing hemodialysis, 29 individuals experienced an improvement (55.8%). While 23 individuals experienced no improved blood pressure (44.2%). Key words: CKD, hemodialysis, improvement of blood pressure.

“…A more detailed description of the simulator including its didactic objectives, models, and implementation is beyond the scope of this paper. More information is available in our recent work [88]. There is no time evolution in the model, and everything is computed in the initialization phase.…”
