Sustainable fiber reinforced polymer (FRP) composites from renewable and biodegradable fibrous materials and polymer matrices are of great interest, as they can potentially reduce environmental impacts. However, the overall properties of such composites are still far from the high-performance conventional glass or carbon FRP composites. Therefore, a balance between composite performance and biodegradability is required with approaches to what one might call an eco-friendly composite. This review provides an overview of sustainable FRP composites, their manufacturing techniques, and sustainability in general at materials, manufacturing, and end-of-life levels. Sustainable plant-based natural fibers and polymer matrices are also summarized, followed by an overview of their modification techniques to obtain high-performance, multifunctional, and sustainable FRP composites. Current state-of-the-art mechanical and functional properties of such composites are then surveyed, and an overview of their potential applications in various industries, including automobile, aerospace, construction, medical, sports, and electronics is provided. Finally, future market trends, current challenges, and the future perspective on sustainable natural FRP composites are discussed.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adsu.202200258.

This cross-sectional design study aimed to describe quality of life and examine factors related to quality of life among older adults in Bangladesh. Convenience sampling was used to recruit 280 older adults from ten villages in two southern districts. The results demonstrate that the majority of the participants reported an overall moderate score of quality of life. Moreover, participants' sleep problems, depression, religiosity, and activities of daily living were negatively correlated with quality of life whereas social support and health service availability were positively correlated with quality of life. Implementing intervention programs upon the significant related factors to improve older adults' quality of life is recommended.

Emotional intelligence plays an important role in regulating the emotions induced by fatigue or stress and it is critically required in nurses who work in dynamic hospital environments. Nurses' emotional intelligence helps them to create a positive work environment in various unfavorable situations in order to provide patients care in a supportive manner. The aim of this study was to assess nurses' emotional intelligence in tertiary hospitals in Dali, the People's Republic of China. The participants were 291 nurses working at two tertiary hospitals. Data were collected via the Demographic Data Form and the Chinese Wong and Law Emotional Intelligence Scale. Descriptive statistics were used to analyze demographic and emotional intelligence data. Results showed that, generally, nurses perceived high levels of emotional intelligence. More specifically, nurses perceived high levels of emotional intelligence in themselves and moderate levels of emotional intelligence in others. They also perceived moderate levels for their ability to regulate their own emotions and for their use of emotion to facilitate performance. This study provides essential information regarding nurses' emotional intelligence. Nurse managers should use this study's results to develop strategies that assist their nurses' efforts to improve emotional intelligence.

The situation of elderly people is an increasingly pressing global concern. This issue is especially challenging for developing countries, where, traditionally, the majority of the elderly people have lived with their family and have been dependent on family support. Nowadays, however, appropriate family support is no longer guaranteed. An assessment tool for measuring active family support would be useful for describing the real living situation of the elderly. The purpose of this study was to develop an active family support scale for elderly people in Bangladesh. This study’s participants were 20 elderly people (aged from 65 to 75 years) who were asked about the support they perceived that they receive from their families. The proposed instrument was found to be a reliable family support scale for Bangladeshi elderly with an internal consistency reliability level of 0.94 (Cronbach’s Alpha Coefficient). The study’s findings are considered transferable to other developing countries. The scale can be used to assess elderly people’s perceived family support in Bangladesh and other developing countries and can support initiatives to improve family support.

Abstract:The proportion of older persons in Bangladesh is gradually increasing due to declining mortality rates and increased life expectancy. Bangladesh faces significant challenges around older persons' health and well-being. The aim of this study was to assess older persons' depression in two southern districts of Bangladesh and the relationship between depression and several socio-demographic characteristics. Data were collected from 280 older persons using Geriatric Depression Scale (GDS-10). Descriptive statistics were used to analyze demographic and depression data. One way classification of analysis of variance (ANOVA) was used to compare different groups of older persons with different socio-demographic characteristics. A large majority (84.3%) of participants reported having depression. Being widowed, being illiterate, the presence of disease(s), living in a nuclear family, and having a low income were found to be significant factors contributing to older persons' depression. The identification of internal and external factors that affect older persons' depression may inform screening and intervention programs and reduce the consequences of depression.
