At the international level, a major effort is being made to optimizethe flow of data and information for health systems management. The studiesshow that medical and economic efficiency is strongly influenced by the levelof development and complexity of implementing an integrated system of epidemiological monitoring and modeling. The solution proposed and describedin this paper is addressed to all public and private institutions involved inthe fight against the COVID-19 pandemic, using recognized methods andstandards in this field. The Green-Epidemio is a platform adaptable to thespecific features of any public institution for disease management, based onopen-source software, allowing the adaptation, customization, and furtherdevelopment of “open-source” applications, according to the specificities ofthe public institution, the changes in the economic and social environment andits legal framework. The platform has a mathematical model for the spreadof COVID-19 infection depending on the location of the outbreaks so thatthe allocation of resources and the geographical limitation of certain areascan be parameterized according to the number and location of the real-timeidentified outbreaks. The social impact of the proposed solution is due to theplanned applications of information flow management, which is a first stepin improving significantly the response time and efficiency of people-operatedresponse services. Moreover, institutional interoperability influences strategicsocietal factors.

A gesture-based interaction system for smart homes is a part of a complex cyber-physical environment, for which researchers and developers need to address major challenges in providing personalized gesture interactions. However, current research efforts have not tackled the problem of personalized gesture recognition that often involves user identification. To address this problem, we propose in this work a new event-driven service-oriented framework called gesture services for cyber-physical environments(GS-CPE) that extends the architecture of our previous work gesture profile for web services(GPWS). To provide user identification functionality, GS-CPE introduces a two-phase cascading gesture password recognition algorithm for gesture-based user identification using a two-phase cascading classifier with the hidden Markov model and the Golden Section Search, which achieves an accuracy rate of 96.2% with a small training dataset. To support personalized gesture interaction, an enhanced version of the Dynamic Time Warping algorithm with multiple gestural input sources and dynamic template adaptation support is implemented. Our experimental results demonstrate the performance of the algorithm can achieve an average accuracy rate of 98.5% in practical scenarios. Comparison results reveal that GS-CPE has faster response time and higher accuracy rate than other gesture interaction systems designed for smart-home environments.

The evaluation and reevaluation of the fundamental didactic principles suppose the acceptance at the level of an instructive-educative activity of a new educational paradigm. Thus, its understanding implies an assumption at a conceptual-theoretical level of some approaches where the didactic aspects find their usefulness by relating to value principles. This situation expresses in fact focus on the formative side specific to the process of didactic communication. Therefore, the understanding of the didactic principles emphasizes concrete modalities of completing the educational activities.

The purpose of this study is to generate essential scientific information regarding the floristic composition and the structures of the ecotone vegetation in the natural forest Codrul Secular Slătioara, because so far no such studies have been carried out in this reserve. Also, the results of this study provide important data, which can be the basis for the development of strategies for the conservation and sustainable use of some herbaceous species, valuable due to genetic and socio-economic, respectively of a regular forest monitoring program. The floristic studies were carried out in the 2020 to 2021 vegetation season. Based on the specialized literature, plant species were identified and then processed from the point of view of bioforms, floristic elements and ecological indices. The economic categories in which the identified species fall were also analyzed. Thus, a total of 292 species belonging to 46 botanical families were identified and their distribution by ecosystems is as follows: in the forest, 90 species were identified, in the lands adjacent to the forest, in the meadows, 202 species were found and in the area of border, 120 species of vascular plants were identified. Most of the species identified in the study area are hemicryptophytes, heliophiles, and eurytherms, which grow on dry to moderately moist, eurytrophic soils. More than 50% of the identified species belong to several categories of useful plants (fodder, medicinal, melliferous, edible).

Simultaneous observations of the solar eclipse on 06/01/2011 were carried out using a Foucault pendulum and a torsion balance. The instruments were installed in a salt mine, where the interference was minimal. Both instruments clearly reacted to the eclipse. We conclude that these reactions should not be considered as being gravitational effects.

The article examines the application of correlation analysis of experimental data in research into the process of extracting bioactive compounds and antioxidant activity in plant extracts from berries and grape pomace. The correlation analysis of the experimental data allowed the establishment of the second order statistical characteristics (autocorrelation function, intercorrelation function and correlation coefficient). Based on the correlation analysis of the experimental data, it was shown that the influencing factor and the measured parameters have zero correlation coefficients for all types of researched extracts. This indicates that they are not independent. Therefore, related mathematical models can be deduced.
