The paper presents the first findings of the children’s subjective well-being survey in Poland, which was conducted among representative sample of over 3000 pupils aged 8, 10 and 12 years from Wielkopolska region in spring 2014. The study is a part of International Survey of Children’s Well-being (ISCWeB) - Children’s Worlds, developed by the International Society for Child Indicators (ISCI). The main purpose of the ISCWeB project is to gain a broad knowledge of children’s lives, their relationships with family members and friends, daily activities, time use and, in particular, their own perceptions and evaluations of their well-being. A particular attention in this paper is paid to the children’s subjective well-being including overall satisfaction with life, measured with use of different psychometric scales, eg. the single item scale on Overall Life Satisfaction (OLS) or the five-item Students Life Satisfaction Scale (SLSS5). Along with overall well-being of the children, it is very important to study various domains of their well-being. In the paper we took into consideration children’s evaluation of their five important life domains: family, school, friends, living environment and self.

Abstract:. More and more often a life cycle thinking is considered as a valuable element of environmental management. Product-based environmental management systems often refer to ecodesign, which can be used in various aspects of product management. Due to their own specificity, small and medium enterprises (SMEs) often encounter difficulties when conducting ecodesign activities. The paper presents a simplified approach based on the life cycle-based environmental classification of products intended for using in SMEs as a starting point for ecodesign. A main goal of the paper is to propose such classification and discuss its role in improving the environmental performance of products. The presented analysis included 50 products classified according to the chosen criteria. As the first step, a cluster analysis has been performed and a distinction between passive and active products has been made. A main conclusion was that the information received from the cluster analysis may be insufficient to be a sole basis for ecodesign. A second classification has been performed basing on the selected environmental impact indicators (GWP100a and CED) calculated for three life cycle stages: a production, an use and a final disposal. The final products' classification reflects the differences in environmental hotspots between products and can be used for supporting the SMEs in implementation of life cycle-based eco-design processes.
