Biological sex estimation is one of the main parameters required in the construction of a biological profile of an unknown deceased person. In corpses in an advanced state of decomposition, skeletonized or severely mutilated, bone analysis may provide the only way to access biological sex. Although the hip bones are the most dimorphic and useful bones for sex estimation, they are often badly preserved and/or fragmented or may not even be present in some cases. For that reason, it is necessary to develop sex estimation methods based on bones less dimorphic. In this study, 13 dimensions of the second cervical vertebra were measured in order to quantify sex-related variation and to generate a simple predictive model based on logistic regression analysis. For logistic regression fitting, 190 individuals from the Coimbra Identified Skeletal Collection were used as a training sample. The resulting model was also evaluated in an independent test sample composed of 47 individuals from the Identified Skeletal Collection of the 21st Century (University of Coimbra). The developed logistic regression model correctly estimated known sex in 86.7 to 89.7 % of the cases. The second cervical vertebra demonstrated to be a useful alternative for sex estimation when other skeletal elements are not available or suitable for analysis. This method seems promising but more reliability studies are required for a more robust validation.

S95ANNALS OF MEDICINE antibiotics can circulate. They also reinforce the need for good hygiene and disinfection of the site between appointments.

The background of the study was that the number of elderly people in the world and Indonesia in particular had increased and was a burden if their health conditions were not given enough attention. One of the issues of concern is the educational evaluation of the use of elderly anthropometer chairs can increase the comfort feeling of the elderly. The purpose of this study was to determine whether the educational use of anthropometer elderly chairs can reduce musculoskeletal complaints and increase the feeling of comfort in the elderly.The study was conducted at the Posyandu of Tumbak Bayuh Mengwi Village, Badung Regency, Bali Province and in the Posyandu RW 12, Bedali Village, UPT, Lawang Public Health Center, Malang Regency because they have similar characteristics. The method used is experimental (quasi experiment) using the same design as the subject (treatment by subject design). The results of the study concluded that musculoskeletal complaints in the initial condition with analysis using the t-pair test, obtained insignificant results (p> 0.05), meaning that there was no difference between the initial conditions.  Analysis Test the difference in the final condition (post) obtained significant results (p * <0.05) meaning that there is a difference between the final condition and the t-pair test analysis on comfort shows a value of p <0.05, meaning that the elderly shows a sense of comfort using elderly anthropometer chair. Recommended for Puskesmas in posyandu to have anthropometer elderly chairs and educate their use in the elderly.
