TikTok is ranked 1st place in the period from January to December 2022. There have been suspicions over TikTok's efforts to further prosper its business through an initiative called Project S via TikTok Shop. Therefore, recently the government established Regulation of the Minister of Trade of the Republic of Indonesia Number 31 of 2003. With this policy, TikTok Shop stopped operating on October 4, 2023 due to violations of socio-commerce rules. This study aims to explore perspectives related to post-closure policies of TikTok Shops in relation to supporting the sustainability of MSMEs in Indonesia. This research uses a qualitative descriptive research method with phenomenology and case study approach. Data collection techniques through interviews with MSMEs and TikTok Shop users and literature studies. It is concluded that although the weakening of the conventional MSME market is not necessarily caused by e-commerce only, this policy is considered a good step to be taken to anticipate the threat of rampant trade from abroad that can threaten Indonesian MSMEs. MSMEs that have indeed utilized the TikTok Shop feature will still be able to use TikTok as a social media service for promotional means, only the transactions will be connected to other platforms.

Com os dados obtidos, fica exposta a necessidade de dar a devida atenção à gestão da área, para assim procurar realizar a mitigação dos problemas que, predominantemente estão associados à ocupação humana, mas que podem tornar-se uma maior ameaça associados às mudanças climáticas previstas para a região costeira.
The Turbulent Years of the Greek Catholic Education System After 1989
Authors: Inántsy-Pap Ágnes , Szilágyi Barnabás 
Published: January 2025

The present study focuses on the revival of denominational education in Hungary after the nationalisation of schools in 1948. It focuses on the decisive role played by Act IV of 1990, which created the legal and infrastructural conditions for the independent operation of denominational educational institutions. The law guaranteed freedom of religious belief and assembly, fostering the emergence of a pluralistic society that recognised the role of Churches in education. The analysis explores the relationship between social attitudes towards church schools and the political situation after the change of regime, and also examines the school takeovers in the Greek Catholic Metropolian Church. Surveys show that the reopening of church schools has received considerable public support, reflecting a nostalgic longing for pre-nationalisation educational values amid dissatisfaction with state education. At the same time, social divisions emerged, with some fearing the re-emergence of religious influence in education and others arguing for a greater role for the churches. The case study on the re-engagement of the Greek Catholic Church in education highlights difficulties such as funding and the need for consensus on educational values among stakeholders. The research draws on interviews with key figures in the Greek Catholic community and relevant literature to illustrate the nuanced dynamics at play during the transition period. Ultimately, this study contributes to our understanding of how historical context, legal frameworks and social attitudes shape contemporary educational policy in Hungary.

Introduction: In England, higher education institutions (HEIs) are modifying their processes to implement support strategies to decrease attrition rates. Some HEIs offer student buddy schemes to foster support networks, and knowledge exchange, build friendships, and increase confidence. Buddy schemes include peer-to-peer support coordinated by institutions, pairing experienced and non-experienced individuals aimed to provide support, advice, and training. At present, there is a lack of evidence capturing Operating Department Practitioner (ODP) students’ opinions about the implementation of a buddy scheme to improve student retention. Thus, to address this gap, a qualitative study with second year ODP students was undertaken.
Methods: Nine second year ODP students in the Midlands, England attended two focus groups. Questions relating to students’ thoughts and perceptions of barriers, and facilitators to a buddy scheme guided the discussion. All focus groups were audio-recorded and transcribed verbatim, and data were analysed using reflexive thematic analysis.
Results: All students regarded the buddy scheme to be potentially advantageous. The reflexive thematic analysis identified three main themes: (1) the value of having a buddy in supporting wellness; (2) the sharing of students’ experiences; and (3) the structure of the buddy scheme.
Implications For Practice: All participants agreed that a buddy scheme would greatly support fellow students both academically and professionally. ODP students see buddy schemes as critical for support and shared experience in completing their studies. Co-design is vital for developing the buddy scheme for ODP students, and further studies are needed to inform the effectiveness of evidence-based buddy schemes.
Determination of an Interval Between Certifications of the Standard Based on the Measurement Process Model in Time

Published: January 2025

Determination and assignment of reasonable intervals between certifications of standards is an important task to ensure the uniformity of measurements. The standards are intended for further transfer of the unit to standards and measuring instruments lower down the verification scheme, which means that exceeding the permissible values by metrological characteristics during operation is unacceptable, since it may lead to unreliability of the further transfer of the unit along the traceability chain. This risk can be reduced by finding the optimal interval between certifications, during which the metrological characteristics of the standard will not exceed the permissible values.The article proposes one of the options for determining the interval between certifications based on the analysis of the measurement model of the standard and modeling the time dependence of the error limits of the estimates of input quantities, including taking into account factors that are not directly involved in the measurement process but influence this process.

In the context of the rapid development of the Russian pharmaceutical industry, there is an urgent need to improve the State Primary Standard for the units of mass (molar) fraction and mass (molar) concentration of organic components in liquid and solid substances and materials based on liquid and gas chromatography-mass spectrometry with isotope dilution and gravimetry (GET 208).As a result of the improvement of GET 208 carried out in 2023, a new installation based on the highperformance liquid chromatography/high-resolution mass spectrometry method was included in the standard. Thus, the functionality of the GPE was expanded in accordance with the current requirements of the domestic industry and for the purpose of Russia’s successful participation in international comparisons in the field of organic analysis now and in the medium term.The article presents materials on the study of the capabilities of the new installation for solving various measurement problems in the field of organic analysis, describes specific analytical techniques and measurement methods, and provides experimental data and summarized results. Based on the completed studies, the metrological characteristics of GET 208 have been improved in terms of reproducing units of mass (molar) fraction of the main component in pure organic substances, mass fraction of organic components in solutions and materials.Improvement of GET 208 made it possible to create a scientific, methodological and instrumental basis for reproducing measurement units for a wide range of organic compounds.

Published: January 2025

Metrological support of gas analytical measurements is carried out by transferring units of molar fraction and mass concentration of components from the State Primary Standard of units of molar fraction, mass fraction and mass concentration of components in gas and gas condensate environs. Reference materials (RMs) for the composition of gas mixtures in cylinders under pressure are used as transmission means, as well as gas mixture generators, the output of which is a gas mixture with known metrological characteristics. The main problem of this method is to ensure long-term stability of the mixture. The use of dynamic methods implemented in gas mixture generators, when the prepared gas mixture is used directly from the generator output, allows to significantly minimize or completely avoid this problem.In recent years, quite a lot of gas mixture generators manufactured by domestic and foreign manufacturers have appeared on the market. Therefore, a comparative analysis of various methods of dosing the initial components implemented in gas mixture generators and used for metrological support of gas analytical measurements seems relevant.The practical significance of the study lies in the analysis of the metrological, technical and operational characteristics of generators implementing various methods of dosing components of gas mixtures, which can be used by manufacturers of these measuring instruments to develop optimal technical solutions in the development and creation of new types of generators and dynamic installations designed to reproduce and transmit units of component content in gas environs.The presented review may be useful for teachers and students of specialized higher education institutions to enhance their knowledge in the field of metrological support for gas analytical measurements.
On the Application of the Bayesian Approach to Estimating the Coverage Interval of a Bounded Measurand
Authors: Stepanov A. V. , Chunovkina A. G. 
Published: January 2025

The problem of estimating the measurement uncertainty near the natural measurand limits is of significant interest to practicing metrologists and is far from being resolved. The article considers the Bayesian approach to constructing an asymmetric coverage interval and estimating measurement uncertainty in the case where the set of permissible values of the measured quantity is bounded. Of particular interest is the case when the measured value is located near the boundary of the set of its permissible values, since the constructed «traditional» symmetric interval corresponding to a coverage factor value of two (for a confidence level of 95 %) goes beyond the boundaries of this set and, as a consequence, do not provide the specified level of confidence probability.When implementing the Bayesian approach, an important starting point is the choice of a priori density distribution. Four options for choosing a prior probability density are considered, including an asymmetric distribution from the family of two-sided power distributions (TSP). Recommendations are given for their selection and application depending on the proximity of the a priori estimate of the lower limit of the measured value, as well as the measured value, to the upper limit of the range of permissible values, relative to the measurement uncertainty value.A specialized software has been developed to estimate the posterior density characteristics (expectation, mode and standard deviation) of measurand distributions and construct the shortest coverage interval, as well as to calculate the confidence level corresponding to the «traditional» coverage interval obtained using expanded uncertainty. The use of this software allows to obtain complete information about the measurement accuracy and to make an informed choice when presenting the measurement result.The results obtained may be of interest to practicing metrologists in the development and certification of measurement techniques, processing of experimental data and presentation of measurement results when characterizing standard samples, as well as specialists involved in the application of methods of probability theory and mathematical statistics in solving practical problems.
Effect of FDM printing direction on the mechanical properties of products
Authors: Raspopina V. B. , Martynova V. V. , Stupina E. A. 
Published: January 2025

The study aims to examine the effect of printing direction in the FDM-technology (Fused Deposition Modeling) on the mechanical properties of products. Laboratory tests of type B specimens were conducted in accordance with GOST 11262-2017 using a Shimadzu AGS-10kNXD tensile tester with a loading rate of 2 mm/ min. The specimens were made of ABS (acrylonitrile butadiene styrene) thermoplastic. Under otherwise equal conditions, the printing direction of the specimens was changed. As a parameter representing this factor, the study adopted the inclination angle of printing filaments in the infill of the specimen α to its longitudinal axis. The test results of FDM specimens showed that at different inclination angles α, a consistent variation in experimental data is observed. The specimen comprises two components: the first is the infill of the specimen; the second is the shell of the specimen. An analysis (based on 3D models of specimens in the slicer) of the filament path in the layers and the structure of each layer revealed that the mechanical properties of test specimens are affected by both components. In the shell of the specimen, this effect is produced by its upper and lower edges. A detailed analysis of models representing each layer of the specimens helped explain the variation in the response of specimens with different α to the action of the same tensile load in terms of the magnitude of the failure load. In particular, the features of the infill structure are such that its effect on the magnitude of failure load is limited by an increase in the angle α from 0 to 45°. A further increase in α leads to a mirror repeat pattern. In this case, the effect of the shell on the magnitude of the failure load corresponds to the range of 0°≤α≤90°. Thus, the conducted research provided insights that can help lay the theoretical groundwork for a procedure for producing FDM parts with specified mechanical properties.

Published: January 2025

This study aims to develop a novel structure of an N-channel adaptive median signal filter with dynamic input exclusion. The proposed design is intended for highly reliable, fault-tolerant modular redundant power supply systems for spacecraft. To investigate the functionality of the proposed N-channel filter, we developed a simulation model for a 7-channel median signal filter using MATLAB Simulink. A model-based design approach was applied to validate the performance of the proposed element using the Altera Cyclone IV EP4CE115F29C7 field-programmable gate array (FPGA). The verification process involved the use of automatic code generation tools within MATLAB Simulink for the FPGA implementation. A novel structure of the N-channel median signal filter was proposed, featuring a dynamic exclusion of unused inputs from the median calculation. This guarantees that only valid input signals from operational modules within the power supply system be included in the median calculation. The simulation results demonstrated that, in contrast to existing counterparts, the proposed filter is capable of reliably outputting the median signal as the number of active input signals decreases from N to 1. The implementation of the filter as an intellectual property (IP) block based on the Altera Cyclone IV EP4CE115F29C7 FPGA demonstrated efficient resource utilisation, occupying 541 logic cells, while fully adhering to the specified operational logic. The proposed structure of the adaptive median signal filter can be employed in highly reliable, fault-tolerant spacecraft redundant power supply systems, maintaining functionality even in the event of multiple module failures, down to the last operational module. The developed solution meets the stringent fault-tolerance requirements of spacecraft power systems.
