The relationship between physical activity and the geographical context is a topic that has received less attention in middle and low income countries compared to studies investigating the association between physical activity and socio-economic factors. In turn, environmental variables are particularly important when studying physical activity levels, because the practice of physical activity depends on the right conditions. Socio-economic and demographic factors contribute significantly to changes in physical activity levels, but environmental changes can also lead to changes in population behavior and adherence to a more or less active lifestyle. Socio-economic changes related to technological advances also influence the population in different ways. In rural areas, this is done by modernizing farming and animal husbandry, improving communication and increasing the consumption of technology previously inaccessible to these population groups. Another issue is urban sprawl, which is associated with lower activity levels physical phenomenon that recorded an accelerated rate.

Children and adolescents with Down syndrome have a range of physical problems and difficulties that can affect their motor development and implicitly social integration. The physical development of children with Down syndrome is often slower. Despite this leaner, children with Down syndrome may participate in sports activities, they will take more time to do some things, but eventually they can do most of them. Cognitive problems - thinking and learning - are characteristic of people with Down syndrome and are usually moderate. Cognitive and behavioral problems include: attention deficit, impulsive behavior, slow learning and speech retardation. People with Down syndrome have a certain degree of difficulty. The degree of disability differs from one person to another and it is impossible to appreciate at the moment of birth how severe it will be. Therefore, it is important for these people to participate in various programs aimed at facilitating the development of motor skills, cognitive and social-emotional development. This research highlights the importance of adapted sports activities, aims to promote the necessary and useful practices in the lives of children and adolescents with Down syndrome. Approved sports programs are considered to offer learning opportunities to help people with Down syndrome overcome barriers to becoming a physically and socially educated person. The aim of the research is to identify sporting activities that generate progress in the physical development of children with disabilities, cognitive and social-emotional development.

Agriculture is a vital activity with major consequences on food security of the population and on regional and local ecosystems, becoming a geostrategic tool important for the economic development of any country. In accordance with the requirements of the European Union, agriculture must be developed and transformed into an ecological agriculture that can offer viable solutions for: satisfying the demand for natural products obtained without the use of fertilizers and chemical substances, while at the same time diversifying and expanding the agricultural sector in harmony with environmental protection and the principles of sustainable development. The aim of the paper is to highlight the evolution of Romanian agriculture in the context of sustainable development according to the requirements of the European Union.

Romania's present economy is characterized by its linearity, an important consumption of non-renewable resources, an incipient form of recycling and a production based on a high consumption of resources at high costs. At European Union level, the desire to evolve and transform the current economies into bio-economies is astringent. A bioeconomy, characterized by the achievement of sustainable production with a minimum consumption of fossil resources and a maximum result, the development of durable products, limiting the effects of pollution, increasing the quality of life and health of the population, reducing dependence on non-renewable resources, increasing food security, recycling rate and waste reduction, outlines a new model of economy that requires society to evolve into a future based on sustainable development. The aim of the paper is to analyze aspects of the bioeconomy and to point out how Romania can transform its current economy into a bioeconomy, while at the same time achieving sustainable economic development.

A distinctive sign of human being, verbal communication is the only and original way of expression man was endowed with by his Creator. A political being par excellence, i.e. gifted with the power of communication, with the desire for communion and need for solidarity, man uses verbal language in order to express themselves and bond with their fellow people. Nowadays, public discourse has deepened its possibilities of attracting, seducing and supporting the achievement of the most various human interests, but as it strayed from the moral religious principles, it lost its substance and became an empty shell and an extremely efficient means of manipulation. Professional ethics is that which should underlie public relationships among a variety of socio-professional categories, correct slippages and provide a model of what coming out in the public space should be, because the estrangement from moral principles always leads to personal failures and catastrophes of human civilisation. The rupture between morality and religion, or, better yet, ethical foundation without religious principles leads to a personal and professional relativisation, which is not at all useful, and to the exclusively economical and financial prioritisation of human activities. This is obvious, particularly at the political, public level, but also in terms of public discourse in general. This study aims to thoroughly research these aspects, in terms of fulfilling this immediate need for the thirst for the truth, for identifying the causes of the immorality of public discourse endeavour and its remediation. The need for morality, authenticity and truth is increasing, because, as falsehood is publicly manifested, the desire for justice and public honesty also emerges.

In strong relation to the multiplication of the roles of those who embrace a didactic career, their initial and lifelong training should be designed and implemented as a coherent and consistent approach, intended to form and develop all professional and transversal competencies necessary for a successful fulfilling of the teaching profession. One of the fundamental components of any psycho-pedagogical training programme dedicated to the teaching career is represented by the teaching training activity. All the actions related to this stage ensure, in a holistic and systemic manner, the necessary basis for the formation and development of the skills required to assume such a complex mission: to be a teacher. Starting from those premises, this paper tries to carry out a qualitative and quantitative analysis on the perceptions of the students who are preparing for the didactic career, on the one hand, and the perceptions of their teacher-mentors from the application schools in Dambovita County, on the other hand, concerning the multitude of aspects implied by the teacher training activity. Another purpose of this investigative approach is to identify some concrete methods to optimise the students’ teacher training, both from a macrostructural perspective, in terms of education policies and current teaching methods, and a microstructural perspective, according to the existing educational practices.

For many countries the marine, costal and maritime sectors represent an important foundation for sustainable development. This is why in order to deliver and achieve it, many countries extend their economy beyond land based activities. A sustainable blue economy in every country depends not only on their maritime and marine zones, but also on their existing economic activities and their issues regarding the environmental, social, and cultural conditions. The main objective of the “blue economy” is to ensure environmental sustainability while promoting social inclusion, economic growth and preservation or improvement of livelihoods (UNCTAD 2014, UNDESA 2014). According to the World Bank in Europe, the Blue Economy represents nearly 5.4 million jobs and generates a gross added value of approximately €500 billion per year. In order to have a sustainable blue economy each country should find the best way to balance sustainability and economic growth to allow optimal use of maritime resources, ensuring at the same time maximum benefit to the environment. Throughout this paper, we tried to emphasize the economic impact of the Blue economy, by analyzing the key sectors: maritime transport, cruise tourism, aquaculture and offshore oil and gas. In each country, some of these sectors need little encouragement and additional governance, while others required better and more efficient planning in order to obtain sustainable outcomes.

Following the story line of Information and Communication Technologies (ICT), since the first room sized computer to the nowadays finger sized processors, there is an uncontrollable increase of the number of devices per person, each time more powerful, as well as a massive access to the Internet. Altogether, this technological movement brought a new paradigm referred to as IoT (Internet of Things), that is quickly affecting almost all dimensions of life, supported on complex (ICT) infrastructures whose safety and security properties need to be addressed carefully. Although in a first look the Cloud architecture showed itself able to handle the requirements, currently this assumption is no longer true. The exponential growth of devices with limited resources exploited some limitations of the Cloud, namely the lack of bandwidth. This happened because, by design, it was architected to deal with high-level data produced by computer-like terminals. Since the introduction of the IoT paradigm, where billions of devises are continuously uploading minimal logs, there was a need to introduce a new middle-ware (at the edge), capable of gathering all elementary information, producing high-level information adequate to the Cloud. This project aimed to design such an edge, with specific requirements to support Smart Cities or similar environments. Following the generic Edge Computing paradigm, the architecture Edge4All currently aims to: accept and deal with different devices security levels; dynamically process the information and provide it through an API; keep historical data to provide a proper big data/machine learning information source; offer a platform to securely manage the deployed devices; and design a dynamic and intuitive dashboard displaying the information, warnings and alert messages, aiming to keep both the regular user well informed and offer an efficient decision-making tool, to related decision makers.

In [1], Buckman Et. al. define a Smart Building as the harmonious integration of intelligent systems, control mechanisms, architecture and construction materials to operate as an entire building system, with adaptability at its core to enable continuous building improvement in terms of energy efficiency, longevity, comfort, and satisfaction. The development of intelligent devices for these Smart Buildings is many times compromised by its form and size. This work explores the limitations due to antenna design restrictions, that are normally responsible for design constraints, power issues, used materials and component placement (e.g. sensors, batteries, etc). The work focuses on the importance of the antenna design, considering many aspects as the presence of surrounding materials, the device’s encapsulation and the proximity between the antenna and other electronic circuits. These aspects are especially important in devices designed for Smart Building applications where form, size, range, and power consumption impose severe restrictions. The proposed design features a reduced size embedded antenna and an ultra-lowpower microcontroller to interface several sensors and actuators. The results obtained have shown that the proposed device can be used for communications, in line-of-sight for up to 4.2 km, in urban environments for up to 1.2 km and for inbuilding communications for up to 152 m, without compromising the low-power features that LoRa supports. This technology allows a node capable of measure CO2, Temperature, Humidity, and Air Pressure to be powered by a CR2477 coin cell (that has a power capacity of 1000 mAh) over a period of 3 years and 7 months, approximately. This demo explores the concept previously introduced in the context of a Smart Building, not only for in-building communications but also for communications between buildings by means of a set of compact LoRa devices in operation.
