O presente trabalho tem como objetivo verificar e comparar o nível de qualidade de vida e saúde mental entre 520 adolescentes de ambos os sexos, com idade de 12 anos a 17 anos de escolas públicas e particulares, de uma cidade do Estado de São Paulo, inserindo-se na área de estudos da saúde. Utilizou-se como instrumento o Questionário de Saúde Geral de Goldberg (QSG) e o Desenho da Figura Humana (DFH), analisados por alguns critérios de Machover (1949) e Hammer (1991) e expressos estatisticamente. Os resultados mostram um melhor desempenho dos estudantes de escola pública em relação à saúde geral, assim como a saúde mental da população feminina quando comparada com a masculina. A conclusão mais importante da pesquisa realizada é o fato de que, mesmo considerando as diferenças apontadas entre a escola pública e a particular, a instituição escola atua como uma variável positiva no controle e manutenção da saúde mental dos adolescentes escolarizados.

This work aims to evaluate the performance of various machine learning algorithms in the prediction of metal forming defects, particularly the occurrence of edge cracking. To this end, seven different single classifiers and two types of ensemble models (majority voting and stacking) were used to make predictions, based on a dataset generated from the results of two types of mechanical tests: the uniaxial tensile test and the hole expansion test. The performance evaluation was based on four metrics: accuracy, recall, precision and F-score, with the F-score being considered the most relevant. The best performances were achieved by the majority voting models. The ROC curve of a majority voting model was also evaluated, in order to confirm the predictive capabilities of the model. Globally, ML algorithms are able to predict the occurrence of edge cracking satisfactorily.

Introduction All types of violence perpetrated to a child or adolescent affect their future interpersonal relationships and may also have implications on mental health, academic, and professional performance [ 1 ]. About half of the people who have suffered at least one type of victimisation have shown behavioural changes [ 2 ]. The main objective of the current study is to analyse the relationship between youth victimisation trauma and the interpersonal reactivity (empathy) in adulthood. Materials and methods The sample was composed by 198 Portuguese adults between 18 and 69 years old ( M = 26.9, SD = 11.7), the majority was single ( n = 168, 84.8 % ), and completed higher education ( n = 96, 48.5%). Participants answered online to a sociodemographic questionnaire, the Childhood Trauma Questionnaire (CTQ) [ 3 ], and the Interpersonal Reactivity Index (IRI) [ 4 ]. The study was conducted following the ethical principles and was approved by the university institutional review board and ethics committee. Results There was a positive association between the total score of child abuse and the Personal Distress ( r = 0.223, p =.002) and Fantasy ( r = 0.160, p = 025) in adulthood. Personal Distress was positively correlated with Emotional Neglect ( r = 0.191, p = .007), with Physical Abuse ( r = 0.235, p = 0.01), and Physical Neglect ( r= 0.252 , p < 0.001). Fantasy was also positively correlated with Emotional Abuse ( r = 0.182, p = .010) and Sexual Abuse ( r = 0.160, p =.024). The total score of the IRI showed a positive correlation with Physical Abuse ( r = 0.174, p = .014) and Physical Neglect ( r = 0.167, p = .019). There was a negative correlation between Empathic Concern and Emotional Neglect ( r = −0.153, p = .032). There was also positive statistically significant correlations between the total score of the CTQ and the occurrence of Emotional Abuse ( r = 0.843, p < 0.001), Emotional Neglect ( r = 0.793 p < 0.001), Physical Abuse ( r = 0.641, p < 0.001) and Physical Neglect ( ...
