Public transportation usage in Delhi has declined, with the Delhi Metro having a significant share. However, due to fare hikes and COVID-19 restrictions, the DM's share has been decreasing further. To improve ridership, a study is being conducted to evaluate the DM's performance and identify areas for improvement in passenger convenience and comfort. The Magenta line is investigated through an on-board survey to collect primary data. The survey covers commuter perceptions of safety & security, financial & economic factors, infrastructure & comfort and functional & operational features. The Relative Importance Index approach is used to analyse the data and evaluate DM performance. An ANN model is also presented to determine the factors influencing the choice to travel on the DM, with the “metro fare per trip” factor being a key consideration. Based on the analysis results, recommendations are made to improve the DM's performance. The study found that safety and security had the highest RII, followed by efficiency and viability, functional and operational features, infrastructure and comfort, and financial and economic factors. The subway fare had the lowest RII. The ANN model is adapted to understand the reasons behind low metro ridership.

Aim: The article aims to describe the technique of designing and fabricating ear prosthesis with the integration of computeraided design and computer-aided manufacturing (CAD/CAM) versus a conventional method. Background: The use of rapid prototyping for prosthesis fabrication preceded by the generation of ear prosthesis design utilising the computed tomography data of the patient are recent advance technologies. Case description: A 6-year-old boy came with congenitally missing right ear. The healthy left ear was mirrored and printed using the 3-dimensional (3D) printer. Since there was a tissue remnant on the affected side of the patient’s ear, the printed ear model was copied in wax. The incorporation of CAD/CAM eliminated the conventional technique involving impression taking of normal ear as a model. Thus, fabrication procedure was simplified, ensuring rapid production. Conclusion: The dimension, shape, and anatomic contour of the ear prosthesis were quite similar to those of the normal ear. This outcome suggested that using the CAD/CAM system to fabricate ear prosthesis from computed tomography data is a practical technique which can be used in a clinical setting. Clinical significance: Rapid prototyping techniques used in this case gave the highest possible level of accuracy in size, shape, and position of the prosthesis. It also decreased the patient appointments and fabrication time compared to the conventional technique.

Kaposi`s sarcoma (KS) is a tumor of endothelial origin, running a protracted clinical course. Four main types of KS have been described namely classical, endemic African, iatrogenic, human immunodeficiency virus (HIV) associated. There has been a spurt in the cases of KS after the HIV epidemic. We report a case of Kaposi sarcoma in a non-HIV elderly Kashmiri male and review the literature.
