Application of Gage R&R methodology for improving the training and evaluation of automatic optical inspection machine operators

The current level of demand by customers in the electronics industry requires the production of parts with an extremely high level of reliability and quality to ensure complete confidence on the end customer. Automatic Optical Inspection (AOI) machines have an important role in the monitoring and detection of errors during the manufacturing process for printed circuit boards. These machines present images of products with probable assembly mistakes to an operator and him decide whether the product has a real defect or if in turn this was an automated false detection. Operator training is an important aspect for obtaining a lower rate of evaluation failure by the operator and consequently a lower rate of actual defects that slip through to the following processes. The Gage R&R methodology for attributes is part of a Six Sigma strategy to examine the repeatability and reproducibility of an evaluation system, thus giving important feedback on the suitability of each operator in classifying defects. This methodology was already applied in several industry sectors and services at different processes, with excellent results in the evaluation of subjective parameters. An application for training operators of AOI machines was developed, in order to be able to check their fitness and improve future evaluation performance. This application will provide a better understanding of the specific training needs for each operator, and also to accompany the evolution of the training program for new components which in turn present additional new difficulties for the operator evaluation. The use of this application will contribute to reduce the number of defects misclassified by the operators that are passed on to the following steps in the productive process. This defect reduction will also contribute to the continuous improvement of the operator evaluation performance, which is seen as a quality management goal.

Relationship between antropometric, corporal composition and performance in young swimmers, boys and girls

The young athlete is physiologically unique from the adult and must be considered differently. The growth and development of their bones, muscles, nerves, and organs largely dictate their physiological and performance capacities (Bar–Or, 1983; Costill & Wilmore, 1994; Stager et al., 2008). Swimming performance, and the required times to reach a competition (TAC), shoud look for those diferences and should be compatibles with them.

Insatisfação corporal e as influencias dos meios de comunicação face à aparência, controlo do peso e obesidade

RESUMO: O objectivo deste estudo é identificar o índice da insatisfação corporal e as influências dos meios de comunicação nas atitudes da mulher face á mudança da aparência, controlo do peso e Obesidade. Pretende-se com este estudo caracterizar e relacionar o índice de insatisfação corporal e a influência exercida pelos meios de comunicação social, fazendo um estudo com base nas diferenças entre dois grupos, numa amostra de 118 participantes do sexo feminino. A amostra de conveniência é composta por 59 mulheres diagnosticadas com obesidade mórbida grau III e grau IV, acompanhada no Serviço de Obesidade do Hospital de Santa Maria e numa amostra de 59 mulheres sem o diagnóstico de obesidade mórbida, com idades compreendidas entre os 19 e os 72 anos. O Protocolo de avaliação foi constituído por um questionário com recolhas dos dados demográficos e métodos utilizados pela mulher para o controlo do peso e duas escalas Sociocultural Attitudes Towards Appearance Questionnaire 3 e Body Shape Questionnaire. Verificou-se uma elevada insatisfação corporal e influências dos meios de comunicação no grupo clínico. Foi verificado ainda que a faixa etária das mulheres entre os 26 aos 39 anos são as que mais sofrem influências dos meios de comunicação face as atitudes para mudar a aparência. ABSTRACT: The objective of this study is to identify the index of body dissatisfaction and the influences of media on women's attitudes will change the face looks. It is intended to characterize the study and associate the index of body dissatisfaction and the influences exerted by the media, control and obesity. Doing a study based on the differences between two groups, a sample of 118 participants were female, the non-random sample consisted by 59 women diagnosed with morbid obesity level III and Grade IV, monitored in the Office of Obesity, Hospital de Santa Maria and a random sample of 59 women without a diagnosis of morbid obesity aged between 19 and 72 years. The Protocol of evaluation was made of a questionnaire with collections of demographic data and methods used by women for weight control and two scales Sociocultural Attitudes Towards Appearance Questionnaire 3 and Body Shape Questionnaire. There was high body dissatisfaction and influences of the media in the clinical group. It was also verified that the age group of women among the 26 to 39 years who are suffering most are the influences of the media to change attitudes towards the dark.

A bot spooler architecture to integrate virtual worlds with e-learning management systems for corporate training

Joining efforts of academic and corporate teams, we developed an integration architecture - MULTIS - that enables corporate e-learning managers to use a Learning Management System (LMS) for management of educational activities in virtual worlds. This architecture was then implemented for the Formare LMS. In this paper we present this architecture and concretizations of its implementation for the Second Life Grid/OpenSimulator virtual world platforms. Current systems are focused on activities managed by individual trainers, rather than groups of trainers and large numbers of trainees: they focus on providing the LMS with information about educational activities taking place in a virtual world and/or being able to access within the virtual world some of the information stored in the LMS, and disregard the streamlining of activity setup and data collection in multi-trainer contexts, among other administrative issues. This architecture aims to overcome the limitations of existing systems for organizational management of corporate e-learning activities.

Effects of an exercise training program in physical condition after liver transplantation in familial amyloidotic polyneuropathy: a case report

Introduction: Familial amyloidotic polyneuropathy (FAP) is a neurodegenerative disease that leads to sensory and motor polyneuropathies as well as functional limitations. So far, liver transplantation is the only treatment for FAP because the mutated protein causing the disease is mainly produced in the liver. With the increasing survival of transplant recipients, functional and cardiovascular problems as consequences of immunosuppressant side effects are increasing associated with sedentary lifestyles and/or retransplantation status. We sought to analyze the impact of exercise training programs on 1 FAP patient’s course long-term after liver transplantation. Methodology. A FAP patient (female; 49 years of age; body mass index 18.8 kg/m2) underwent a liver transplantation 133 months before assessment. She was assessed for body composition, isometric quadriceps muscle strength, functional capacity, fatigue, and levels of physical activity before and after a 6-month period of combined exercise training. Results: After the exercise training program, almost all variables were improved, namely, total body skeletal muscle mass, proximal femoral bone mineral density, quadriceps strength, maximal oxygen consumption on 6 minutes walk test (6mwt) or VO2peak, total ventilation on 6mwt, and fatigue. The improvement in distance on 6mwt (69.2 m) was clinically significant. Preintervention the levels of physical activity were below international recommendations for health; after the program they achieved the recommendations. Conclusion: The results showed an improvement in functional capacity with a decrease in future disability risk associated with a better lifestyle with respect to physical activity levels in 1 patient.

Composição corporal, capacidade funcional e tempo em lista activa em indivíduos submetidos a transplante hepático por polineuropatia amiloidótica familiar

PAF–Doença neurodegenerativa relacionada com a produção hepática de Transtirretina met30 e respectiva deposição sistémica principalmente no sistema nervoso periférico, que se traduz clinicamente por uma neuropatia sensitivo-motora de início periférico e com graves limitações funcionais em alguns casos. Actualmente, o único tratamento conhecido para a PAF é o transplante hepático com medicação agressiva para o metabolismo muscular e ósseo e para a produção de força. Não existe actualmente qualquer caracterização quantitativa da composição corporal ou capacidade funcional para esta população. Objectivos do estudo: comparar a composição corporal e capacidade funcional entre doentes PAF transplantados (PAFT) e um grupo de indivíduos aparentemente saudáveis (GC); analisar possíveis relações entre composição corporal e capacidade funcional e tempo de espera para a cirurgia.

Índice de massa corporal (massa corporal.estatura-2) como indicador do estado nutricional de adultos: revisão da literatura

São discutidas as virtudes, limitações e possíveis aplicações do índice de massa corporal (IMC), também chamado de índice de Quételet, que é calculado pela divisão da massa corporal em quilogramas pelo quadrado da estatura em metros, como indicador do estado nutricional de adultos. Baseado numa revisão ampla da literatura, os limites de corte para a definição de sobrepeso (IMC ³ 25) e desnutrição energética crônica (IMC < 18,5) são apresentados e discutidos. Conclui-se que apesar de não representar a composição corporal de indivíduos, a facilidade de sua mensuração e a grande disponibilidade de dados de massa corporal e estatura parecem ser motivos suficientes para a utilização do IMC em estudos epidemiológicos, em associação (ou não) a outras medidas antropométricas, até que metodologias de campo que expressem a composição corporal sejam desenvolvidas para tais estudos.
