Published: January 2025

Relevance. The largest share of online purchases by Russians was made in the popular category "travel and accommodation" which requires the transfer of personal data by a tourist. It follows from statistical reports on the development of the tourism industry. Personal data of a tourist as a consumer of services are used in contracts with tour operators, hotels, carriers, guides who carry out individual activities. Such data are taken into account in business processes to form personal tourist experience and customize targeted advertising with its help. In this regard, the issue of improving the mechanisms for protecting tourists personal data is becoming relevant.

The purpose is to establish the content of personal data protection in the field of tourism.

Research objectives: to determine the state of personal data protection; establish legal requirements for tour operators to ensure personal data protection of tourists; summarize the jurisprudence on research subject.

Methodology. The article is based on such methods as: analysis, description, interpretation, generalization, formal-legal.

Results. In the course of the study, it was found that the protection of tourists personal data is carried out by the norms of several federal legislative acts; tour operators independently establish a list of necessary information about the tourist for conducting activities and determine the policy regarding customers personal data processing; claims against tour operators with reference to the norms of civil legislation on the protection of personal data as independent requirements are not presented.

Conclusion. Personal data of tourists are protected by special federal legislation and many departmental regulations prescribing the obligation to ensure the safety of personal confidential information about the tourist and the customer of the service. In cases of this category, other legal methods of protecting the intangible good in question are used (norms of the law on personal data, administrative and criminal legislation), the explanation for which is seen in the unresolved issues related to the legal regime of two phenomena - personal data and private life.

Authors: VINAYAK GOUR  , SEVRAS HINGWE  , CHANDRAKANT  , JYOTI RAGHUWANSHI
Published: January 2025

Objectives: The transversus abdominis plane (TAP) block is a relatively new regional anesthesia technique that provides analgesia to the parietal peritoneum as well as the skin and muscles of the anterior abdominal wall. Despite a relatively low risk of complications and a high success rate using modern techniques, TAP blocks remain overwhelmingly underutilized. The objective is to compare the analgesic efficacy of 0.25% bupivacaine and 0.25% bupivacaine with 0.9 μg/kg dexmedetomidine in TAP block as a part of a multimodal analgesia regimen for post-cesarean delivery pain management.
Methods: Patients more than 18 years old posted for elective/emergency caesarean section in ABVGMC, Vidisha, Madhya Pradesh. After approval from the institutional ethical committee and written informed patients consent, 20 each pregnant women were included in the both study group. Group A: TAP block with 0.25% bupivacaine 20 mL each side Group B: TAP block with 0.25% bupivacaine with 0.9 μg/kg dexmedetomidine 20 mL each side. We studied TAP block in patients posted for elective caesarean section.
Results: The women received 0.25% bupivacaine or 0.25% bupivacaine with 0.9 μg/kg dexmedetomidine. The median visual analogue scale (VAS) for pain was significantly higher in the bupivacaine Group A at 12 h with compare to Group B. Overall, there was no difference in VAS score at 0.5, 2, 4, 6, and 24 h demands between the two groups. The mean time to first rescue analgesia in Group A was 14.6±5.5 h and in Group B was 16.8±4.2 h.
Conclusion: We conclude that the using dexmedetomidine as an additive to bupivacaine in ultrasound-guided TAP block for elective/emergency caesarean section provides prolonged duration of post-operative analgesia, and lowered VAS pain scores. The addition of dexmedetomidine to bupivacaine also reduced the total dose of opioid requirement in the first 24 h after caesarean section.

Optimizing Type II Diabetes Prediction Through Hybrid Big Data Analytics and H-SMOTE Tree Methodology
Authors: K.S. Praveenkumar  , R. Gunasundari
Published: January 2025

In the last few years, Type II diabetes has become much more common worldwide, presenting major problems for both healthcare systems and individuals. Utilizing big data analytics has shown potential as a means of forecasting and managing persistent illnesses, like Type II diabetes. This paper proposes a novel hybrid approach that combines big data analytics techniques with an H-SMOTE tree algorithm for the prediction of Type II diabetes. The suggested method addresses the problems of class imbalance present in medical datasets and improves prediction accuracy by combining steps of feature selection, data preprocessing, and classification. In order to prepare raw data for analysis, it must first be cleaned, standardised, and transformed. Then, feature selection techniques are used to identify the most important factors that help predict Type II diabetes. This approach streamlines the predictive model and lowers its dimensionality. In the classification phase, an algorithm called the H-SMOTE tree is used. This method combines two existing techniques: the Hoeffding Adaptive Tree (HAT) and Synthetic Minority Oversampling Technique (SMOTE). The H-SMOTE tree tackles imbalanced data by creating synthetic samples for the under-represented class, while also adapting the decision tree structure as it receives new data.   Experiments show that this approach is effective in accurately predicting Type II diabetes. The researchers found that the H-SMOTE tree model outperformed other machine learning methods, both classic and recent ones. In other words, it was more accurate in predicting T2DM cases. This was evident in terms of several metrics, including how well it identified true positives (sensitivity), how well it avoided false positives (specificity), and its overall performance captured by the AUC-ROC score. Additionally, the proposed method displays resilience and scalability, rendering it apt for managing extensive medical datasets frequently encountered within healthcare domains.

The sector of agriculture is one of the most crucial in the context of ensuring food security as well as in the care for sustainable development. The food security can be improved through several aspects, one of them being the agriculture system transition, implementing more and more regenerative measures. From the agriculture transition, due to the efforts needed to achieve the
expected level of green transition, farmers themselves are expected to benefit less than the future society and nature in a whole. Yet both financial institutions and agriculture companies have not reached a common understanding, what requirements should be in place to establish mutually beneficial financial products to achieve the expected level of transition in a timely manner.
The aim of this study is to evaluate funding options for agriculture transition in Baltic countries – Latvia, Lithuania, and Estonia. In total, for screening purposes, 29 different Banks operating in the Baltics were identified. The analysis of the financial product purposes provides a high-level perception, that loans, even if not indicating signs of support for green transition, may still
support the improvements of overall country and society sustainability. The expert judgement was used to find potential links with the United Nations Sustainable Development Goals (UN SDGs) identifying the potential SDGs that could be tackled when providing the financing to the specific purpose. Only two banks are observed to provide financial products that can be assessed as focused on green transition, and this research shows that financial products for agriculture companies willing to transition to sustainability are not broadly available.

Authors:   Latvia University of Life Sciences and Technologies, Latvia, Kļaviņš Atis
Published: January 2025

Robotic process automation (RPA) is relatively new software technology that is quickly being adopted by companies around the globe to free office workers from routine, monotonous and rule-based tasks letting them invest their time in higher complexity and value tasks. While big companies have money, time and workforce resources to implement RPA, small and medium enterprises (SME) fall behind in their effort to start using RPA despite the fact that for this segment of organizations RPA would be useful as it presents the opportunity to re-arrange their limited resources and delegate part of work to software.
To address this situation, the aim of this paper is to conduct systematic review of literature regarding RPA appliances in enterprises in order to find out how to implement RPA successfully, what processes to give to RPA, and how SMEs can implement RPA better. During the review main guidelines on how to implement RPA in enterprise in general and which processes to delegate to RPA in particular were identified as well as challenges RPA implementation might bring to company.
It was also noted that there is missing research on how to adopt RPA specifically in SMEs segment. The conclusion is that SMEs aimed RPA implementation guidelines are missing.

This study investigates the distribution and carbon content of organic soils in Latvia, leveraging machine learning techniques alongside remote sensing and National Forest Inventory (NFI) data to enhance the precision of organic soil mapping. Our approach integrates data from various sources, including airborne laser scanning (ALS) data, digital elevation models (DEM), depth-to-water (DTW) and wet area maps (WAM), and historical organic soil data. By classifying over 24,000 soil probing measurements across Latvia into distinct peat layer thickness categories, we develop a machine learning model that categorizes the thickness of the organic layer with notable accuracy. Our findings indicate that the model, particularly when employing the xgbTREE algorithm and over-sampling method, successfully identifies areas with peat layers thicker than 40 cm, demonstrating a significant improvement over traditional mapping methods. The study reveals an underestimation of organic soil coverage in Latvia by previous estimates, suggesting a broader distribution than recognized, with the model achieving an accuracy of 0.86 and a kappa value of 0.67. This research not only underscores the efficacy of integrating machine learning and remote sensing for soil mapping but also highlights the critical role of accurate data and models in determining organic soil distribution. The insights gained from this study are vital for policy-making and environmental planning, offering a more detailed understanding of Latviaʼs peatland resources and their conservation needs.

Published: January 2025

Sustainability, green growth and the European Union Green Deal principles are the cornerstones that should and will affect our lives. The aim of the paper is to provide possible improvements to higher education programmes to promote the implementation of the EU Green Deal as a factor for changes in business. The research is based on investigations into the entrepreneurship students’ knowledge of the EU Green Deal. A theoretical analysis of literature and policy documents were investigated to develop an appropriate questionnaire for the survey of Latvian university students. The research methods involve measures of central tendency and location, T-test, ANOVA and correlation analysis. The research results indicate that business curricula involve courses on Sustainable Development and universitiesʼ role in teaching the Green Deal because the students who hold experience in entrepreneurship report similar results if compared with students without experience in entrepreneurship. Students’ knowledge of the EU Green Deal should be improved since there are a number of aspects where the answers were not correct. This, in turn, prompts the need to strengthen and diversify education, so that business transformation towards the Green Deal is successful. The curricula should be further improved, as it allows students to better understand EU and global trends in saving the planet and put the knowledge into practice in their companies.

Published: January 2025

In this paper, we introduce the concepts of Ces?ro summability and Tauberian
theorem in neutrosophic normed spaces. We study that Ces?ro summability in
neutrosophic norm space does not imply ordinary convergence, and we give an
example in support of our statement. We define slowly oscillating sequences
in neutrosophic normed spaces and prove that Ces?ro summability of slowly
oscillating sequences implies ordinary convergence in neutrosophic normed
spaces. Finally, we define q?bounded sequence with respect to the
neutrosophic norm and also show how it relates to oscillating sequence in
neutrosophic normed spaces.

class of single-valued strictly pseudocontractive mappings in the sense that
the possession of L-Lipschitzian and demiclosedness properties as well as
closed and convex set of fixed points are guaranteed. Also, we introduce an
extended Mann and an extended Ishikawa iteration schemes for approximating a
common fixed point of a finite family of mappings. Furthermore, using the
extended Mann and the extended Ishikawa iteration schemes, we prove weak and
strong convergence theorems for our new classes of extended strictly
pseudocontractive and pseudocontractive mappings, respectively. Numerical
examples are also included to illustrate our results. The results obtained
improve, complement and extend the results on multi-valued and single-valued
mappings in the contemporary literature.
Perfect fluid spacetimes obeying certain restrictions on the energy-momentum tensor
Authors: De Krishnendu , De Uday
Published: January 2025

This paper is concerned with the study of a perfect fluid spacetime endowed
with the various forms of the energy-momentum tensor T. We establish that a
perfect fluid spacetime endowed with covariant constant energy-momentum
tensor represents a dark matter era or the matter content is a perfect fluid
spacetime with vanishing vorticity; whereas a perfect fluid spacetime
endowed with Codazzi type of T represents a dark matter era or the expansion
scalar vanishes, provided ?1 remains invariant under the velocity vector
field ?. Also, we show that a perfect fluid spacetime with pseudo-symmetric
energymomentum tensor represents a dark matter era or a phantom era,
provided the velocity vector field annihilates the curvature tensor.
Moreover, we characterize T-recurrent and weakly-T symmetric perfect fluid
spacetimes with Killing velocity vector field and acquired that the perfect
fluid spacetimes represent a radiation era in the first case and a stiff
matter for the last one.

Published: January 2025

We establish multidimensional analogues of one-dimensional stable limit
theorems due to H?usler and Luschgy (2015) for so called explosive
processes. As special cases we present multidimensional stable limit
theorems involving multidimensional normal-, Cauchy- and stable
distributions as well.

Authors: Ammar Aymen , Jeribi Aref , Saadaoui Bilel
Published: January 2025

In this paper, we introduce and study the essential approximation S-spectrum
and the essential defect S-spectrum in a right quaternionic Hilbert space.
Our results are used to describe the investigation of the stability of the
essential approximation S-spectrum and the essential defect S-spectrum of
linear operator A subjected to additive perturbation K such that (AK + KA +
K2 ? 2Re(q)K)Rq(A + K)?1 or Rq(A + K)?1(AK + KA + K2 ? 2Re(q)K) is a
quasi-compact operator in the right quaternionic Hilbert space.
Self-adjointness of magnetic Laplacians on triangulations
Authors: Anné Colette , Ayadi Hela , Chebbi Yassin , Torki-Hamza Nabila
Published: January 2025

The notions of magnetic difference operator or magnetic exterior derivative
defined on weighted graphs are discrete analogues of the notion of covariant
derivative on sections of a fibre bundle and its extension on differential
forms. In this paper, we extend these notions to certain 2-simplicial
complexes called triangulations, in a manner compatible with changes of
gauge. Then we study the magnetic Gaus-Bonnet operator naturally defined in
this context and introduce the geometric hypothesis of ??completeness which
ensures the essential self-adjointness of this operator. This gives also the
essential self-adjointness of the magnetic Laplacian on triangulations.
Finally we introduce an hypothesis of bounded curvature for the magnetic
potential which permits to caracterize the domain of the self-adjoint
extension.
On (L,N)-fuzzy betweenness relations
Authors: Zhao Hu , Zhao Yu-Jie , Zhang Shao-Yu
Published: January 2025

In this paper, aiming at the shortcomings of the definition of LRG-Galois
connections in [51], we give a new definition of (strong) LRG-Galois
connections, and we also introduce the notions of (L,N)-fuzzy betweenness
relations. By using a strong LRG-Galois connection in our sense, it is shown
that the category of (L,N)-fuzzy betweenness spaces and the category of
(L,M)-fuzzy convex spaces are isomorphic. Moreover, it is proved that the
lattice of (L,M)-fuzzy convex structures and the lattice of (L,N)-fuzzy
betweenness relations are complete lattice isomorphic.

Published: January 2025

We introduce Chen inequalities for slant Riemannian submersions from
cosymplectic manifolds onto Riemannian manifolds. We provide trivial and
non-trivial examples for slant Riemannian submersions, investigate some
curvature relations between the total space, the base space and fibres.
Moreover, we obtain Chen-Ricci inequalities on the vertical and the
horizontal distributions for slant Riemannian submersions from cosymplectic
space forms.
Common fixed points for set-valued generalized contractions on a metric space with graphical structure
Authors: Maiti Pallab , Sultana Asrifa
Published: January 2025

This manuscript deals with existence of common fixed points and coincidence
points for setvalued generalized f -contraction in the setting of metric
space having graphical structure. This result enables us to derive fixed
points for set-valued generalized contractions on a metric space having
directed graph. The main theorem generalizes and improves several results in
the literature. An invariant approximation result on a normed linear space
is derived from our main result. As an implementation of our main result, we
deduce the sufficient criteria for occurrence of solution for the Caputo
fractional differential equation.

Published: January 2025

Este artigo realiza uma revisão sistemática da literatura para investigar o papel dos empreendedores institucionais (EI) na transição sociotécnica do biometano, uma fonte renovável análoga ao gás natural de origem fóssil. Utilizando palavras-chave e operadores booleanos em bases de periódicos, identificamos 64 artigos, dos quais 20 foram selecionados para análise aprofundada. Os resultados destacam a predominância de pesquisas em regiões como os Países Baixos e os Estados Unidos, revelando uma lacuna teórica em relação ao biogás e biometano em contextos emergentes, como o Brasil. A revisão de literatura evidencia que os empreendedores institucionais desempenham um papel crucial na mobilização de recursos e na construção de redes de suporte, utilizando funções dos sistemas de inovação tecnológica (TIS) para superar barreiras institucionais e técnicas. Este estudo fornece uma compreensão mais rica das condições que favorecem o sucesso de inovações sustentáveis no setor energético e identifica lacunas que abrem caminhos para futuras pesquisas empíricas.
Balance Identification to Reduce the Risk of Falls in the Elderly
Authors: Norlinta Siti Nadhir Ollin , Irfan Muhammad
Published: January 2025

Background: Balance disorders are a major factor in influencing some elderly disability rates in Indonesia. Especially the incidence of falls that can cause a decrease in quality of life. Therefore, it is important to take preventive measures in the form of identifying the risk of falling in the elderly group with the Time Up and Go Test (TUG) balance test.
Research method: A quantitative study with a descriptive cross-sectional approach was used in the Tridadi elderly group, Sleman Regency, Special Region of Yogyakarta. The TUG test results were grouped into two; high risk of falling if the respondent completed the TUG test in more than 13.5 seconds and the normal category if the respondent was able to do the test in less than 13.5 seconds. The data were analyzed and presented based on a frequency table with sampling using the purposive sampling method.
Results: From a total of 29 Tridadi elderly group populations, the average total test duration was 10.68 seconds. Male respondents were on average faster in completing the test than female respondents 9.3:10.84. A high risk of falling was found in 4 out of 29 respondents (13%) all of whom were female with an age range of 48-69 years.
Conclusion: The level of risk of falling in the Tridadi elderly group shows that the female elderly group tends to have a higher risk of falling with a longer TUG test duration than men. By identifying the risk of falling figures, further steps need to be taken related to the analysis of risk factors and preventive and rehabilitative steps in the population at risk of falling.

Concentration disturbances among students are an important issue in higher education, especially in the digital era filled with distractions. This study aims to explore the effectiveness of brain gym exercise Exercise as a non-pharmacological intervention to enhance students' concentration. The method used is a quasi-experimental design with a pre-and-post test without a control group, involving 50 students from the D3 Physiotherapy Politeknik Unggulan Kalimantan. Concentration measurements were conducted before and after the intervention using a grid concentration test form. The results show a significant (P<0,05)  increase in students' concentration levels. Therefore, brain gym exercise can serve as an effective alternative for improving students' concentration, especially when performed regularly and continuously. This study contributes to the development of a holistic approach to addressing concentration disturbances in the academic environment.
