The presented paper concerns the issues of communication networks applied to monitoring and control of reactive power compensator for small hydroelectric plants installed in areas distant from urban agglomerations. Ethernet, CAN, Modbus and GPRS transmission protocols has been used. Industrial programmable controller as a data collector has been used also.

Parental work migration can pose important risks for adolescents, such as joining inappropriate peer-groups, poor results in education or school drop-out. It can also facilitate positive changes in young people’s behaviour, as many become aware of the sacrifices their parents make to provide them with a better lifestyle and education and behave responsibly in return. Given that the literature highlights both negative and positive transformations related to parents’ migration, our aim is to address the impact of migration on adolescents left behind in rural Romania from their own perspective. We focus on teenagers’ experiences of separation from their mother, father or both, in different situations (family life, communication and rela-tionships, caring and concern for others, school achievements, future migration plans). Young people’s agency – their capacity to self-educate and organise themselves to perform well at school and in everyday activities following parental migration – is less studied in Romania. Thus, in addition to making the reality of these adolescents better known, our approach provides information that can be turned into policy solutions aimed at improving their life quality.

Technological progress is the driving force behind industrial development. It is a multidimensional and multi-level phenomenon. In this article we focus on its three manifestations: information and communication technologies (ICT), Industry 4.0 and agile manufacturing. The aim of this article is to analyse the relationship between these constructs as they are undoubtedly interrelated. ICT plays a key role, but it is not a goal itself. They are a prerequisite for the implementation of Industry 4.0, but together with it they serve to achieve agility by the manufacturing system and, as a result, achieve a competitive advantage by companies operating in turbulent and unpredictable environment. The literature findings in this paper are part of a broader study conducted on the impact of ICT on agility of SMEs operating in India. Therefore, we include also subsections showing the level of this relationship in Indian SMEs.
