    © Crown 2019. The supervised learning classification algorithms are one of the most well known successful techniques for ambient assisted living environments. However the usual supervised learning classification approaches face issues that limit their application especially in dealing with the knowledge interpretation and with very large unbalanced labeled data set. To address these issues fuzzy classification method PROAFTN was proposed. PROAFTN is part of learning algorithms and enables to determine the fuzzy resemblance measures by generalizing the concordance and discordance indexes used in outranking methods. The main goal of this chapter is to show how the combined meta-heuristics with inductive learning techniques can improve performances of the PROAFTN classifier. The improved PROAFTN classifier is described and compared to well known classifiers, in terms of their learning methodology and classification accuracy. Through this chapter we have shown the ability of the metaheuristics when embedded to PROAFTN method to solve efficiency the classification problems

    DNA Methods to Identify Missing Persons

    Human identification by DNA analysis in missing person cases typically involves comparison of two categories of sample: a reference sample, which could be obtained from intimate items of the person in question or from family members, and the questioned sample from the unknown person-usually derived from the bones, teeth, or soft tissues of human remains. Exceptions include the analysis of archived tissues, such as those held by hospital pathology departments, and the analysis of samples relating to missing, but living persons. DNA is extracted from the questioned and reference samples and well-characterized regions of the genetic code are amplified from each source using the Polymerase Chain Reaction (PCR), which generates sufficient copies of the target region for visualization and comparison of the genetic sequences obtained from each sample. If the DNA sequences of the questioned and reference samples differ, this is normally sufficient for the questioned DNA to be excluded as having come from the same source. If the sequences are identical, statistical analysis is necessary to determine the probability that the match is a consequence of the questioned sequence coming from the same individual who provided the reference sample or from a randomly occurring individual in the general population. Match probabilities that are currently achievable are frequently greater than 1 in 1 billion, allowing identity to be assigned with considerable confidence in many cases

    FUNDAMENTOS: Há escassa literatura sobre a avaliação dos resultados cirúrgicos e do impacto da cirurgia de blefaroplastia superior na qualidade de vida dos pacientes. OBJETIVO: Avaliar o impacto na qualidade de vida dos pacientes submetidos à cirurgia de blefaroplastia superior. MÉTODOS: Estudo prospectivo com questionário padronizado, em mulheres adultas submetidas à blefaroplastia superior e avaliadas após 90 dias para estimativa do impacto cirúrgico na qualidade de vida e de complicações. RESULTADOS: Foram avaliadas 41 mulheres adultas saudáveis (idade mediana 53 anos) no período de junho de 2005 a março de 2006. O questionário apresentou alta consistência interna. O elemento de qualidade de vida de maior impacto na primeira semana foi relacionado à percepção da aparência física, e o de menor impacto foi relacionadoà convivência com as pessoas próximas. A cicatrização hipertrófica foi a principal complicação tardia. O grau de satisfação com a cirurgia relacionou-se significativamente com a ausência de efeitos indesejados (p<0,01). CONCLUSÕES: Os autores sugerem ferramenta consistente para avaliar o impacto dessa intervenção cirúrgica na qualidade de vida dos pacientes. Destacam ainda altos índices de satisfação dos pacientes com a blefaroplastia superior.<br>BACKGROUND: There is scarce literature on assessing surgical results and the impact of upper blepharoplasty on quality of life of patients. OBJECTIVE: To evaluate the impact on quality of life of patients submitted to upper blepharoplasty. METHODS: A prospective study using a standardized questionnaire applied to adult women submitted to upper blepharoplasty and evaluated 90 days later to estimate the surgical impact on quality of life and complications. RESULTS: Forty-one healthy adult females (median age of 53 years) were evaluated from June 2005 to March 2006. The questionnaire showed high internal consistency. The quality of life element with greater impact on the first postoperative week was related to physical appearance perception and that of lesser impact was associated to relationship with relatives and close friends. Hypertrophic scar was the main late complication. Satisfaction levels with the surgery were significantly related with absence of undesirable effects (p<0.01). CONCLUSIONS: The authors suggest a consistent tool to evaluate the impact of this surgical procedure on quality of life of patients. High satisfaction levels with upper blepharoplasty stood out
