Well-Being at Work: A Cross-Sectional Study on the Portuguese Nutritionists.

This exploratory, nationwide cross-sectional study was performed to investigate the well-being of Portuguese nutritionists, in addition to outlining their professional and demographic profile. Descriptive analyses were carried out to determine the measures relating to centralising tendency and dispersion of the sample. We compared means and proportions through t-tests and Analysis of Variance (ANOVA). The sample size was 206 individuals, respecting a minimum of eight respondents per item to validate the instrument. We recruited Nutritionists from Portugal nationwide using the list of electronic mail provided by the Order of Nutritionists. We sent an electronic mail to all the Nutritionists registered in this Order. We also used messaging applications and social networks (Instagram, Facebook) to reach Nutritionists who were not accessing electronic mail. Most respondents are women (92.5%), young (mean age = 31.4 ± 8.07 years; 54.2% of participants aging under 30 years), single, and with no children. More than half are Catholic (73.8%) and have less than ten years of nutritionist undergraduate completion (55.4%). The only variable that influences well-being at work is the economic variable Household Monthly Income. Those who earn less than €500.00 per month perceive themselves at a lesser state of work well-being than those who earn from €2501.00 to €5000.00 per month.

Scheduling in cloud manufacturing systems: Recent systematic literature review.

Cloud Manufacturing (CMFg) is a novel production paradigm that benefits from Cloud Computing in order to develop manufacturing systems linked by the cloud. These systems, based on virtual platforms, allow direct linkage between customers and suppliers of manufacturing services, regardless of geographical distance. In this way, CMfg can expand both markets for producers, and suppliers for customers. However, these linkages imply a new challenge for production planning and decision-making process, especially in Scheduling. In this paper, a systematic literature review of articles addressing scheduling in Cloud Manufacturing environments is carried out. The review takes as its starting point a seminal study published in 2019, in which all problem features are described in detail. We pay special attention to the optimization methods and problem-solving strategies that have been suggested in CMfg scheduling. From the review carried out, we can assert that CMfg is a topic of growing interest within the scientific community. We also conclude that the methods based on bio-inspired metaheuristics are by far the most widely used (they represent more than 50% of the articles found). On the other hand, we suggest some lines for future research to further consolidate this field. In particular, we want to highlight the multi-objective approach, since due to the nature of the problem and the production paradigm, the optimization objectives involved are generally in conflict. In addition, decentralized approaches such as those based on game theory are promising lines for future research.

Comparison of three optical biometers: IOLMaster 500, Lenstar LS 900 and Aladdin.

PURPOSE: To evaluate the results of optical biometry using the IOLMaster 500, Lenstar LS 900 and Aladdin in eyes with cataract. METHODS: In 231 eyes of 152 patients with cataract, the measurements of 3 different biometers were retrospectively compared. Paired comparisons were performed for axial length (AL), mean keratometry (mean K) and anterior chamber depth (ACD). RESULTS: In only 197 of the 231 eyes (85.3%), it was possible to obtain reliable measurements of AL with all the three devices. It was not possible to determine AL in 16 eyes (6.9%) with Lenstar LS 900; in 19 eyes (8.2%) with Aladdin; and in 20 eyes (8.6%) with IOLMaster 500 possibly related to the severity of lens opacification (the corneas had good transparency in the eyes included in the study). There was a statistically significant difference in AL between IOLMaster 500 and the remaining two biometers (P = 0.03). However, the amount of difference was considered clinically not significant (0.04 mm). The mean keratometry (mean K) was determined in 203 eyes (87.9%) with all the three devices. Differences in mean K were between - 0.1 and 0.06 Diopters (D), which were considered neither statistically (P > 0.05) nor clinically significant. The anterior chamber depth (ACD) was determined in 197 eyes (85.28%) with all the three biometers. The differences between the three devices (0.03 to 0.13 mm) were not statistically significant and considered also clinically not significant. CONCLUSIONS: There were no clinically significant differences between these 3 biometers in AL, mean K and ACD.

Ansiedade social na infância e pré-adolescência: adaptação para o português de Portugal da SASC-R / Social anxiety disorder in childhood and pre-adolescence: adaptation of the SASC-R for european Portuguese

A Escala de Ansiedade Social para Crianças (forma revista) - SASC-R destina-se a avaliar as experiências de ansiedade social e de evitamento das crianças e pré-adolescentes no contexto das relações com os pares. Neste estudo, pretende-se validar para a população portuguesa a SASC-R, utilizando a estrutura proposta pelos autores da escala original, através da análise fatorial confirmatória (AFC). Procedemos à aplicação da SASC-R numa amostra de 486 crianças entre os 9 e os 15 anos. Os resultados indicam que a escala replica os fatores da versão original, possui boa consistência interna e uma validade de constructo bastante satisfatória. Este estudo sugere que a SASC-R é uma escala útil na avaliação da ansiedade social em crianças.

The Social Anxiety Scale for Children (revised form) - SASC-R evaluates the experience of social anxiety and avoidance felt by children and pre-adolescents in the context of relationship with their peers. This study aims to validate the Portuguese version of the SASC-R by confirmatory factor analysis using the structure proposed by the authors of the original scale. In a survey donewith 486 children between the ages of nine and 15 years, the results show that the scale reproduces the original factors, has a good internal consistency and a quite satisfactory construct validity. This study suggests that the SASC-R is a useful scale on the evaluation of social anxiety among children.
