Introduction - Forensic Dentistry has great importance in the identification process, especially when professionals receive only the cephalic  portion of the body for analysis. The purpose of this study is to assess sexual dimorphism and age estimation using the  Transverse Cranial Index. Materials and methods - We studied a sample of 160 dry skulls, 80 males and 80 females, who belonged to individuals over the age of 20 years, and with age and sex known with absolute certainty. The studied skulls belonged to people whose relatives had not claimed their remains in the time established by the Cemetery administration and they were being sent for cremation. The following measurements were carried out:  the distance between the basion and bregma (maximum cranial height) and the distance between the eurio and eurio (maximum cranial width) and from these we calculated the Transverse Index. Results - According to statistical analysis, there was a success rate of 81.5% by logistic regression and 76.25% with discriminant analysis. The results were verified and the confidence interval was average throughout the test. The method of multiple linear regression used to predict the age was used, noting that the model was not significant (p = 0.3223). Conclusions - The results allowed the development of statistical methodology for the diagnosis of sex and age on future observations.

Introduction: Forensic Dentistry has a great importance in the process of human identification, especially when the professional has only the cranium to analyze. The aim of this study is to verify the sex dimorphism and age estimation by the facial measurements. Materials and Methods: A sample of 150 dry skulls was studied, 80 male and 70 female, which belonged to individuals aged over 20 years old. The sex and age of the individuals were surely known. The skulls that have been studied belonged to people whose bones have not been claimed by their relatives in the determined time by the cemetery and were being sent for incineration. The following measurements have been done: frontal curve and distance between bregma and mastoid process. Results: According to the statistical analysis, there was success rate of 71.8% by logistic regression and 70% by the discriminant analysis. It was also verified the mean and confidence interval by t test and used the method of multiple linear regression to predict age, evidencing the model was not significant (p = 0.5390). Conclusion: The results enable the development of a statistical methodology to identify gender and age in future observations.

Natural disasters, crime, and accidents can happen anytime. The hardest part after the tragedy is to identify the victim,especially if their bodies are no longer intact. Tooth is one of the most important parts of the body that can beidentified even if the body is already destroyed. One of the difficulties in the identification process is the inadequacy ofante mortem data of the victims, especially the children. In this paper, it discussed about dental ID card that can beuseful as summary information on cases of abduction or in the process of identifying the bodies in the event of adisaster. Odontogram in the dental identification card can help the dentist to create a plan of care for children and canalso assist in the gathering of data for epidemiological purposes that give data about the health condition of the child'smouth. Such data can be used as a basis for policy-making is a step to prevention, which is expected to improve theoral health of children in Indonesia. This card must be given to the patient and always taken when they go to thedentist. All providers of oral health services, including UKGS role in updating the data on a regular basis. It was concluded that the oral health information is very helpful in making the right decisions that improve oral health.Dental identification card is a real little effort in realizing it, have a major impact, simple but useful.

Objective: Age estimation is an important element in the forensic investigation, being one of the data primary sources to establish the identity of living people or unknown mortal remains. The methods used for this purpose are those based on individuals’ bones and teeth development. Since dental radiographs assume major role in the forensic context, this article aims to show, by means of literature review, the importance of dental radiographs as an aid in human identification process, particularly in the age estimation.Conclusion: The forensic dental examination contributes significantly to human identification, no matter if it is a living, in advanced decay, skeletonized or charred body. Therefore, it is important to raise awareness among dental professionals about the need to properly record and archive the information and data obtained during the daily clinical routine, since the greatest support for identification in forensic dentistry, mainly the individual’s age estimation, comes from clinical documentation produced daily by clinicians, especially dental radiographs.

Abstract Introduction Literature shows that exercise moderates the relationship between sleep and emotional distress (ED.) However, it is unclear whether different types of exercise, such as aerobic and strengthening, affect this relationship differently. We investigated the moderating role of two types of exercise (aerobic and strengthening) regarding the relationship between ED and sleep. Methods Our analysis was based on data from 2018 National Health Interview Survey (NHIS), a nationally representative study in which 2,814 participants provided all data. Participants were asked 1) “how many days they woke up feeling rested over the past week”, 2) the Kessler 6 scale to determine ED (a score >13 indicates ED), and 3) the average frequency of strengthening or aerobic exercise per week. Logistic regression analyses were performed to determine if the reported days of waking up rested predicted level of ED. We then investigated whether strengthening or aerobic exercise differentially moderated this relationship. Covariates such as age and sex were adjusted in the logistic regression models. Logistic regression analyses were performed to determine if subjective reporting of restful sleep predicted level of ED. We investigated whether strengthening exercise or aerobic exercise differentially moderated this relationship. Covariates such as age and sex were adjusted in the logistic regression models. Results On average, participants reported 4.41 restful nights of sleep (SD =2.41), 3.43 strengthening activities (SD = 3.19,) and 8.47 aerobic activities a week (SD=5.91.) We found a significant association between days over the past week reporting waking up feeling rested and ED outcome according to K6, Χ2(1) = -741, p= <.001. The odds ratio signified a decrease of 52% in ED scores for each unit of restful sleep (OR = .48, (95% CI = .33, .65) p=<.001.) In the logistic regression model with moderation, aerobic exercise had a significant moderation effect, Χ2(1) = .03, p=.04, but strengthening exercise did not. Conclusion We found that restful sleep predicted reduction in ED scores. Aerobic exercise moderated this relationship, while strengthening exercise did not. Further research should investigate the longitudinal effects of exercise type on the relationship between restful sleep and ED.

The Work Ability Index (WAI) is a validated and widely used tool in occupational research. However, normative values for physical therapists (PTs) by age and sex are lacking. Although the nature of PTs’ work is physically demanding, it is unknown whether muscular fitness is associated with their WAI. This study sought to provide reference WAI data for Spanish PTs and to evaluate the association between PTs’ muscular fitness and WAI. Data on WAI of 1005 PTs were collected using a questionnaire. A subgroup (n = 68) performed a battery of physical tests including grip strength, push-ups and back-extension endurance. Associations between muscular fitness and WAI were evaluated using logistic regression controlling for various confounders. PTs aged 50 years or older had lower WAI scores than their younger counterparts. PTs with high back-extension endurance scored 3.5 (95% CI) higher in the WAI than those with low endurance. No associations were found between grip strength or number of push-ups and WAI. Our findings seem to highlight the importance of muscular fitness in PTs, especially the back-extension endurance.

Generally, there is a significant relationship between some acoustic measures (F0 and formant parameters) and the body size of speakers; however, data become less clear when age and sex variables are controlled. To date, no other vocal parameter apart from F0 has been studied in relation to body size. In the present study, correlations between a set of 27 parameters of the Multi-dimensional Voice Program (Kay Elemetrics Corp.) and 4 body measures were obtained from 134 speakers of both sexes belonging to one age group (20–29 years). Correlations within sex groups were null or very weak, and all significant coefficients were below .35.

Abstract. Riverbank erosion affects river morphology and local habitat, and results in riparian land loss, property and infrastructure damage, and ultimately flood defence weakening. An important issue concerning riverbank erosion is the identification of the vulnerable areas in order to predict river changes and assist stream management/restoration. An approach to predict areas vulnerable to erosion is to quantify the erosion probability by identifying the underlying relations between riverbank erosion and geomorphological or hydrological variables that prevent or stimulate erosion. In the present work, a statistical methodology is proposed to predict the probability of the presence or absence of erosion in a river section. A physically based model determines the locations vulnerable to erosion by quantifying the potential eroded area. The derived results are used to determine validation locations for the evaluation of the statistical tool performance. The statistical tool is based on a series of independent local variables and employs the logistic regression methodology. It is developed in two forms, logistic regression and locally weighted logistic regression, which both deliver useful and accurate results. The second form, though, provides the most accurate results as it validates the presence or absence of erosion at all validation locations. The proposed tool is easy to use and accurate and can be applied to any region and river.
