Background: Estimation of stature is one of the commonly used methods in forensic analysis to establish identity of individuals. Estimation of stature from fragments of long bones is done by deriving linear regression equations. The objective of the present study was to derive a simple regression equation for estimating length of the tibia using the morphometry of proximal end of tibia. Materials and methods: In this descriptive study carried out in the department of anatomy of a medical college, anthropometric measurements of proximal end of 150 dry human tibiae were collected irrespective of the sex and side. The parameters measured included the mediolateral length of the proximal end, the anteroposterior length of the medial and lateral condyle of tibia, anteroposterior length of the intercondylar area, and the circumference of proximal end of tibia. The measurements were done using Vernier calliper and measuring tape. Length of the tibia was estimated by using simple regression analysis. Results: The following linear regression equations were derived. Length of tibia can be calculated by, 29.2749 + (1.1925 × Mediolateral length) ±1.1926, 27.6418 + (2.333 × Anteroposterior length of lateral condyle) ±1.132, 21.8342+(3.2614 ×Anteroposterior length of medial condyle) ±1.328, 33.542 +(0.8952 × Anteroposterior length of intercondylar region) ±1.474, 23.1902 +(0.76379 × Circumference of proximal end) ± 1.134 Conclusion: The study revealed that there is a positive correlation between the measurements of proximal end of tibia and its length. The equation derived would help in forensic analysis to estimate the stature of an individual. KEY WORDS: Humans, Tibia, Linear Models, Forensic Anthropology, Body Height.

Background: The COVID -19, a novel coronavirus disease spreading across the globe, most countries including India have ordered the closure of all educational institutions which has put the academic calendar to a functional standstill. The pandemic forced many institutions to shift to online mode using Google meet, Zoom, Microsoft teams, etc. The teaching-learning methodologies have been revamped globally due to the covid outbreak that many schools and teachers around the world are coping with alternative ways for delivery of instructions. In spite of its multiple advantages, there are quite a few limitations faced by online teaching such as lack of student-teacher interaction, social isolation, network connectivity issues, etc. The deviation from traditional teaching to online teaching prompted this study to assess the perceptions of students towards online learning. Aim: The purpose of the study was to determine the perceptions of medical students towards online teaching during the lockdown Materials and Methods: After obtaining approval from the institutional ethical committee, the questionnaire-based study was conducted on 150 first-year medical students of Adichunchanagiri Institute of medical sciences, B G Nagara. The data obtained were statistically analyzed and tabulated. Results: Responses have clearly shown that students prefer the traditional method of teaching such as lecture, discussion, etc. over online classes due to multiple issues faced during online teaching. Conclusion: Online teaching is the most common method and the best platform to keep learners/students engaged and safe during the lockdown period for Covid-19. Despite being in the technological era, students are still more inclined towards face-to-face teaching rather than e-teaching due to various reasons. Administration and faculty members should take appropriate measures to improve e-teaching quality and help students in better learning. KEY WORDS: Perception, Students, online teaching.
