In this paper, we describe secure gateway for Internet of Things (IoT) devices with internal AAA mechanism, implemented to connect IoT sensors with Internet users. Secure gateway described in this paper allows to (1) authenticate each connected device, (2) authorise connection or reconguration performed by the device and (3) account each action. The same applies to Internet users who want to connect, download data from or upload data to an IoT device. Secure Gateway with internal AAA mechanism could be used in Smart Cities environments and in other IoT deployments where security is a critical concern. The mechanism presented in this paper is a new concept and has been practically validated in Polish national research network PL-LAB2020.
Renewable energy development is crucial for resolving global warming issues and achieving
sustainable development goals. The objective of this paper is to reveal renewable energy trends
using statistical data to identify the most developed technologies in the field, their distribution by
territory, checking the interrelation between investments in R&D and patent activity.
The changes in total investments made in renewables are studied for 2004–2019 and the increasing
trend has been observed with some fluctuations in certain years, major current investments in solar
and wind energy are detected. The dynamics of international patenting activity in solar and wind
technologies, geothermal and fuel cells, the total number of PCT applications over the past 10 years
by geographic region are considered. The results show some differences across various renewable
technologies. Solar is the most patented, wind and fuel cells are less patented but solar and wind
have shown an uptrend for the last five years, while fuel cell technologies showed a decline after
2008. Geothermal is the least patented.
The comparison between investment and patent application trends in renewables undercovers some
important issues – the leading role of Japan in patenting under the PCT procedure, while China is
a major investor in renewable energy; the US and Europe with big investments in renewables are
also leading in patent registration.
Correlation between investment in R&D and patenting activity in the field of global renewable
energy should be emphasized (correlation coefficient R = 0,849 for 2002–2019). Since private
and public investment is strongly stimulated by domestic renewable energy policies, IP indicators
can help identify policy instruments and their effectiveness within the further research
framework.
This article discusses the issue of hypermodernity, which was studied as part of the research project Poles in the World of Late Capitalism. The article presents biographical models of hypermodernity and strategies of coping with hypermodern ideology, that is, cyclothymias, conversions, and hypermodern episodes.
Previous research reported about high comorbidity between asthma and neurodevelopmental disorders. Recently, asthma was associated also with executive functions poorness. The current study aimed to investigate the verbal and visual memory performances among fifteen asthmatic kindergarten children compared to the performances of other fifteen healthy kindergarten children. The results showed that the asthmatic group revealed poor performances in the immediate short term verbal memory and the verbal working memory tests but not in the verbal learning test as it was compared to the healthy group. In addition, the asthmatic group revealed poor performances in the visual memory tasks compared to the healthy group. The results were explained in light of the assumption that poor executive functions might be interfere the process of managing the attentional resources which are needed through the process of memory encoding and retrieval.
The suitability of a land plot in a real estate market could be identified as a good investment because the land plot is deemed as popular. This activity is important for economic growth, who is one of the sustainable development goals. Mostly, all research in this field is focused on sustainability as well as the opinions of professionals. However, this field should be explored from another side which is based on real geodata. Criteria and its weight are very important in decision support systems. The correct criteria can help in selection of the best real estate object for an investment, but it is not only useful but also and a challenging task that has not yet been solved. The methods of research are data graphical analysis, correlation, decision supporting systems, etc. The research aims at determining the significance of the connections and using them as the criteria in the selected decision supporting method. In addition, it will be determined which decision supporting method defines the most suitable object for investment. These new criteria are proposed for operation in the land use models. Furthermore, it has been identified as one criterion, which is significant in the urban and agrarian territories. Also it turned out, that the land plot is the most active when it is as far from a densely built-up residential territory as possible and as close to a school, and when the land plot is as large as possible.
Bilingualism has long been observed in Silesia, a part of Poland which lies on the border between three cultures and languages: Polish, Czech and German. Some lin-guists consider Silesian one of the Polish dialects, others think it should be treated as a separate language. During the communist times the inhabitants of Upper Silesia were discouraged from using the local dialect at school or in public institutions. The situation has changed a lot since 1989 with the promotion of regional studies. Short characteristics of Silesian will be presented in the fi rst part of the paper.The main part of the project presents the results of a questionnaire which focuses on young people’s attitudes towards Silesian. The respondents (100 Polish students of English philology) fall into two groups – half of them identify themselves with the region and the other half do not. How many respondents speak Silesian? Where do they use it and how do they evaluate it? What is the linguistic stereotype of a person living in Upper Silesia? These are just a few questions that suggest themselves in the context of the study.
Speech is almost never delivered in ideal quiet conditions. On the contrary, the acoustic signal reaching a listener's ears is degraded by background noise and reverberations. The current study investigates the perception of the voicing contrast of initial stops in English by Polish non-native listeners. Previous research showed that Polish learners do not match native speakers of English in production and perception of English voiced and voiceless stops, which results from different phonetic implementations of voicing in the two languages. In the current study, two groups of Polish listeners recognised voicing of English initial stops in one-syllable words both in quiet and in six-talker babble. The results revealed different patterns of recognition for the two conditions. The place of articulation interacted significantly with voicing both in quiet and in noise, however results obtained suggest that performance in noise did not simply reflect the performance in quiet.
Drawing on extensive qualitative research into experiences of migration and settlement among Central and East European (CEE) migrants living in Scotland, this article examines the role of intersecting emotional and material (in)securities in migrant families’ decision-making regarding and experiences of longer-term settlement. The article queries fixed or given understandings of either ‘family’ or ‘secu-rity’ and explores the complex and sometimes contradictory relationship between them. In so doing, it makes a number of significant and interconnected theoretical and empirical contributions to existing research in the field of family migration. Through a critical analysis of the relationship between family and (in)security the article offers nuanced insight into the ways in which family processes of reunion, separation and (re)formation link to decisions regarding migration and settlement. The intersecting and sometimes contradictory forms of emotional and material support, obligation and vulnerability which both family relations and processes of migration and settlement entail are critically analysed by bring-ing together theoretical frameworks of social (in)security and understandings of family as ‘made’ rather than ‘given’. Finally, attention given to the temporal aspects of (in)security, as well as the transnational aspects of migrants’ lives, provides new ways of understanding the open-endedness of decision-making processes relating to migration and settlement, especially where these involve multiple decision-makers.
