Estimulação cognitiva em adultos e idosos de uma Faculdade Aberta à Terceira Idade / Cognitive stimulation in adults and elderly of a Faculty Open to Senior Citizens / Estimulación cognitiva en adultos y ancianos en una Universidad Abierta a Personas Mayores

Este artigo tem como objetivo investigar a efetividade de um treinamento de estimulação cognitiva (EC) em adultos e idosos participantes de uma Faculdade Aberta da Terceira Idade (FATI). Trata-se de um estudo exploratório e intervencionista, em que foram realizadas intervenções de estimulação cognitiva em um grupo de adultos e idosos participantes da FATI, n=19. Esperamos que este artigo contribua com as discussões e intervenções em estimulação cognitiva na área da Gerontologia, contribuindo para uma melhor sistematização das pesquisas aplicadas.

This article aims to investigate the effectiveness of a cognitive stimulation (CE) training in adults and elderly participants of a Faculty Open to Senior Citizens (FATI). This is an exploratory and interventional study in which cognitive stimulation interventions were performed in a group of adults and elderly participants of the FATI, n=19. We hope that this article contributes to the discussions and interventions in cognitive stimulation in the area of Gerontology, contributing to a better systematization of applied research.

Photosynthetic capacity and water use efficiency in Ricinus communis (L) under drought stress in semi-humid and semi-arid areas

ABSTRACT Castor bean is one of the crops with potential to provide raw material for production of oils for biodiesel. This species possess adaptive mechanisms for maintaining the water status when subjected to drought stress. A better understanding these mechanisms under field conditions can unravel the survival strategies used by this species. This study aimed to compare the physiological adaptations of Ricinus communis (L.) in two regions with different climates, the semi-arid and semi-humid subject to water stress. The plants showed greater vapor pressure deficit during the driest hours of the day, which contributed to higher values of the leaf temperature and leaf transpiration, however, the VPD(leaf-air) had the greatest effect on plants in the semi-arid region. In both regions, between 12:00 p.m. and 2:00 p.m., the plants presented reduction in the rates of photosynthesis and intracellular CO2 concentration in response to stomatal closure. During the dry season in the semi-arid region, photoinhibition occurred in the leaves of castor bean between 12:00 p.m. and 2:00 p.m. These results suggest that castor bean plants possess compensatory mechanisms for drought tolerance, such as: higher stomatal control and maintenance of photosynthetic capacity, allowing the plant to survive well in soil with low water availability.

Sugars levels of four sugarcane genotypes in different stem portions during the maturation phase

ABSTRACT Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil and climate conditions the varieties differ on the maturation curve. Thus, studies that allow establishing maturation curves of different sugarcane genotypes in the local soil and climate may indicate the proper harvesting period to ensure better quality of the raw material. This study aimed to analyze the levels of soluble sugars during the maturation phase and assess the technological and productivity indexes of four irrigated sugarcane genotypes in the region of Rio Largo, Alagoas. The experiment was conducted in randomized blocks in a 4 x 2 x 5 factorial: four genotypes (RB92579, RB98710, RB99395 and RB961003), two stem portions (internodes 1-4 and internodes 5-8) and five seasons (82, 49, 25, 13 and 3 days before harvesting), each treatment with three replications. Internodes 1-4 showed the highest levels of reducing sugars, while the largest accumulation of sucrose and total soluble solids occurred in internodes 5-8. RB99395 genotype showed more stability in the sugar levels during sugarcane maturation, which can indicate early maturation and high agricultural yield.

Reflexões sobre o envelhecimento humano e o futuro: questões de ética, comunicação e educação / Reflections on human aging and the future: ethics, communication and education issues

O acelerado envelhecimento populacional e o aumento da longevidade no Brasil trazem muitos problemas que afetam a população idosa, como a manutenção de sua saúde e uma boa qualidade de vida. Passa então a existir uma preocupação ética com a qualidade dos programas dedicados AA essa faixa etária e a formação e capacitação de profissionais que atendam a essa demanda. Atualmente, há uma grande necessidade de um novo posicionamento social ante essas questões, justificando a realização de uma reflexão sobre os aspectos éticos, da comunicação inter e intrageracional e da educação para o envelhecimento, desafios a serem enfrentados pela sociedade brasileira contemporânea. È o que propõe este estudo, que trata do idoso na sua relação com a sociedade atual.

The accelerated aging of the population and the increase in longevity in Brazil bring many problems that affect the elderly population, such as the maintenance of their health and a good quality of life. For this reason, there is now an ethical concern about the quality of programs targeted at this age group the training and qualification of professionals to meet this demand. Currently, there is great need for a new social positioning in relation to these issues, which justifies the implementation of a reflection on ethical, inter- and intra-generational communication and aging education, the challenges to be faced by the Brazilian society. This is what this study proposes, dealing with the elderly in their relationship with contemporary society.
