The purpose of the study is to identify the essence of public administration of municipal property. The theoretical and methodological relevance of this research paper lies in the fact that economists do not consider the issue of publicity in the management of regional property as a priority in modern realities. The goal set determined the need to solve the following problem: to determine the economic effect of managing regional property during its digitalization. To achieve the purpose of the study, methods of statistical information processing were used. The state property of the Perm Territory is considered as the objects of research. Digitalization of property in the regions will allow you to convert analog data streams into digital format and transfer existing communications into computer technologies. This process will be the first step towards achieving the goal, then it will be necessary to complete the automation of all processes (in the infrastructure), and provide modern equipment with digital technology support.

Background: Coupling digital technology with traditional neuropsychological test performance allows collection of high-precision metrics that can clarify and/or define underlying constructs related to brain and cognition. Objective: To identify graphomotor and information processing trajectories using a digitally administered version of the Digit Symbol Substitution Test (DSST). Methods: A subset of Long Life Family Study participants (n = 1,594) completed the DSST. Total time to draw each symbol was divided into ‘writing’ and non-writing or ‘thinking’ time. Bayesian clustering grouped participants by change in median time over intervals of eight consecutively drawn symbols across the 90 s test. Clusters were characterized based on sociodemographic characteristics, health and physical function data, APOE genotype, and neuropsychological test scores. Results: Clustering revealed four ‘thinking’ time trajectories, with two clusters showing significant changes within the test. Participants in these clusters obtained lower episodic memory scores but were similar in other health and functional characteristics. Clustering of ‘writing’ time also revealed four performance trajectories where one cluster of participants showed progressively slower writing time. These participants had weaker grip strength, slower gait speed, and greater perceived physical fatigability, but no differences in cognitive test scores. Conclusion: Digital data identified previously unrecognized patterns of ‘writing’ and ‘thinking’ time that cannot be detected without digital technology. These patterns of performance were differentially associated with measures of cognitive and physical function and may constitute specific neurocognitive biomarkers signaling the presence of subtle to mild dysfunction. Such information could inform the selection and timing of in-depth neuropsychological assessments and help target interventions.

Guidelines And Standards

The digital signature of documents and degrees is a topic widely discussed in the Federal Public Administration. Several laws and ordinances were created to standardize the issuance, validation and legal validity of digitally signed documents in national territory, such as the ordinances created by the Ministry of Education (MEC) to regulate the issuance of degrees in digital format. These ordinances created guidelines and standards that must be adopted by Federal Universities for the signing of in digital format. The main objective of this work is to study these ordinances, the main technologies and digital signature standards used in the literature to create a digital signature system model for University of Brasília-UnB, which complies with the MEC and ICP-Brazil standards. Moreover, the model must be developed with the main standards and technologies in the market, cohesive to the current UnB architecture, easy to maintain and update to new standards that may emerge, and also be a fully open source project. An architectural model and a prototype in Java language were developed using XAdES4j library as a microservice intermediated by the bus used in UnB. The prototype developed was compared with the current digital signature system named C3Web. The comparative tests and results between the two solutions showed that the current system used in UnB does not perform the signature in accordance with the standard proposed by the MEC, in addition to being a private system using proprietary technologies for the execution of digital signatures. The tests performed with the proposed model demonstrated that it performs the digital signature in accordance with the XAdES-T standard, regulations of the MEC and ICP-Brazil. In addition, the solution presented a performance comparable to the current system used by UnB with a little more effective security than the current system used. The current model developed in this work can be a basis for the creation of future subscription systems for Brazilian Universities.

Abstract Older adults comprise a highly heterogeneous group that engages with digital media in varying ways, therefore a large variation in technology support needs is likely. This study examines the nature of support for using digital media among older adults. We conducted in-depth qualitative interviews with older adults (age 59+) in Hungary, the Netherlands, and Switzerland (N=58) in 2019 exploring: (1) whether and how older adults receive support in using digital media; and (2) older adults’ perceptions of whether the support they receive meets their needs. We began with open coding, then conducted consensus meetings to identify themes and coding schemes, and wrote memos to share findings and ensure reliability across coders. We find that older adults voice a highly varying range of need for technical support as well as varying instances of both receiving and not receiving technical help. Participants report receiving help from different informal (e.g. spouses) and formal (e.g. computer classes) sources. However, support may not be immediate, posing challenges for older adults who depend on the availability of their support sources. Importantly, we also find that there are older adults who are quite self-sufficient in the ways they use digital technology. For older adults needing support, greater access to community-based support may help those without satisfactory options in their own social circle. Given our findings that older adults can have great ease with solving technology-related problems, peer-driven support networks where older adults can offer support to others may be an effective approach to providing digital technology guidance.

Background. Integrating mechanical cultivation measures with herbicides adapted to the state and degree of weed infestation effectively reduces segetal vegetation. Biostimulants in turn have a positive effect on plant growth and development and increase plant resistance to the adverse effects of various stress factors. The aim of the study was to evaluate the production and economic effects of cultivation of the table potato cultivar Gawin after the use of mechanical measures, herbicides and herbicides with biostimulants. Material and methods. The field study was carried out in the years 2012–2014 at the Przedsiębiorstwo Wielobranżowe Soleks, in the town of Wojnów located in the Mazowian Voivodeship, on light soil with quality class IVb which is classified as the very good rye complex. The test plant was the medium-early table potato cultivar Gawin. The experimental variants comprised of five methods of using mechanical and chemical measures: the control variant – only mechanical weeding and four variants with the use of herbicides or the use of herbicides and biostimulants: Harrier 295 ZC (linuron + clomazone), Harrier 295 ZC (linuron + clomazone) + Kelpak SL, Sencor 70 WG (metribuzin) and Sencor 70 WG (metribuzin) + Asahi SL. The standard gross margin method was used for the economic assessment of the methods of cultivation. Results. The total tuber yield on variants with mechanical and chemical cultivation was 22.5% higher compared with the control variant, and the marketable yield was 39% higher. Despite the relatively high costs incurred to protect the potato from weeds, integrating mechanical measures, herbicides and biostimulants was cost-effective. Conclusion. The highest yields of the cultivar Gawin (total and marketable) and the best economic effect in relation to the control variant were obtained using intensive mechanical weeding as well as the herbicide Sencor 70 WG and the biostimulant Asahi SL.

The article presents preliminary results of the comprehensive assessment of the economic effect for the infrastructure owner from transportation by trains composed with the innovation freight cars with axial load of 27 tons at the specific areas (grounds). Comprehensive economic assessment for the infrastructure owner consists in taking into account changes of expenses for improvement of technical properties of the new car, as well as the expenses for changes of the operation properties of the car handling areas, in particular: • one-time expenses for putting infrastructure of the areas of cars handling with the axial load from 25 to 27 tons in compliance with the new technical requirements; • financial results due to increase of carrying-capacity by means of increase of the weight at the permanent train length; • change of the current and one-time expenses for train traction composed of the innovation cars of increased carrying-capacity when changing the locomotive series and the number of section-kilometers per the unit of transportation operations.Calculations performed for the routes Chegdomyn – Vanino and Chelutay – Nakhodka indicated that effect of transportation in the innovation cars can be both positive and negative for the infrastructure owner depending on the operation and economic properties of the handling area (volume of transported freight in the examined cars, maintenance process of the locomotive runs, etc.).Taking into account the one-time costs for putting the superstructure in compliance with the technical requirements, the financial results of JSC “RZD” is getting worse at the examined routes.Obtained results have preliminary nature as more detailed accounting of expenses is required for putting infrastructure of the train handling areas composed from the cars of axial load 27 tons in compliance with the technical requirements.

Fitting platforms of variable freight storage lengths are used for transportation of rails and other cargo up to 25 m long. The use of innovative fixation for transportation on the fitting platforms contributes to enlargement of the range of cargo transported on such rolling stock and establishes conditions for safe transportation of such cargo.To evaluate the effectiveness of the arrangement of long cargo transportation on the fitting platform, this study examines two 25 m long rail transportation options. The transportation option involving two coupled 14.62 m platforms, when the cargo is fixed on the coupled platforms with the standard method is the basic option. The new option involves transportation of the 25 m long rails using 80-feet fitting platforms 25.62 m long at the coupling axes and multiway fi xation sets. A calendar year is assumed as the estimate period. The transported volume is assumed equal for each option, under considering the operating conditions of the calculation unit — one coupling of universal platform (or one 80-feet fitting platform), reducing the financial results to a ton of transported cargo. The value of the annual economic effect for the freight owner (Eyearown) is determined as the change of the freight owner’s expenses due to usage of the new option relative to the basic transportation option.The economic assessment of the transportation is performed considering the interests of each member of the transportation process and tested based on specific data. The results demonstrate the effectiveness of implementation of the technical and technological solution under consideration.
