Published: December 2023

Abstract
This paper presents a contribution to the field of numerical solutions for contact problems, which pose significant challenges in engineering and simulations. Specifically, we address the intricate task of connecting bodies that have been discretized using non-conforming and non-overlapping meshes. Our primary focus lies in investigating the efficacy of the mortar method with a segment-to-segment approach. In this context, we provide a concise overview of the underlying theoretical framework and present our implementation in the MATLAB programming environment. To ascertain the reliability and accuracy of our proposed methodology, we conduct a rigorous validation study by comparing the outcomes obtained from our implementation with those derived from the widely adopted commercial software, ANSYS. To enable a comprehensive evaluation, we select specific benchmark problems that involve the interaction of two elastic bodies. Through a meticulous analysis and comparison of results, we demonstrate the effectiveness and robustness of our approach. The findings of this study contribute substantively to the advancement of numerical techniques for solving contact problems. The validated methodology not only establishes a solid foundation for future research endeavors but also offers a reliable framework for conducting simulations in this domain. Furthermore, the insights gained from this study can potentially facilitate the development of more efficient and accurate computational algorithms for addressing contact problems encountered in various engineering applications.

Abstract
The economy of Ecuador is characterized by a high predominance of micro and small enterprises. Multiple of these organizations are created each year and, as a general rule, the highest percentage die in their first year. Which is a strong reason for the abundance of research aimed at understanding the nature of their behavior. These studies assume different streams of analysis, which are developed from dissimilar areas of knowledge. This particular research seeks to evaluate how multiple variables affect the high annual mortality rate shown by micro and small enterprises. For this purpose, the descriptive statistics of the behavior of the variables are initially used to later identify, through a discriminant analysis, the variables that best explain a possible closure, which are: the attitude of entrepreneurs to face risks and failures, their perseverance, as well as the effectiveness of the feasibility studies that support the birth of the ventures.

EMOTIONAL SECURITY AS THE OPTIMIZING FACTOR OF COGNITIVE PROCESSES
Authors: Andriyenko Elena 
Published: December 2023

The article is devoted to the issue of emotional security as a factor of personal development in psychological and social contexts. The subject matter of the article is emotional security as the factor of optimization of cognition. Emotional security has been defined as a feeling of acceptance and confidence that promotes optimal cognitive and adaptive processes. For a long cognitive processes (memory, attention, perception, understanding, thinking, decision-making, action and impact) time have been interpreted exclusively as rational ones while the emotional and sensory sphere was understood as irrational. In the context of modern psychology the connection between cognitive processes and emotional sphere has become obvious. It has been concluded that emotional security is an important condition for optimizing cognitive processes in the context of learning and creating a safe educational environment. It has been stressed that the cognitive effects of four types of emotions should be taken into account: 1) emotions of novelty – fear, surprise, interest which affect the processes of sensation, perception and attention; 2) emotions of attack – anger, rage and heroism which affect motor and mental processes; 3) emotions of acquisition – pleasure, joy and delight which determine memory processes; 4) emotions of loss – disgust, sadness and despair which facilitate the processes of forgetting and indirectly contribute to the acceleration of thinking and concentration of effort.Key words: Emotions, Feelings, Emotional Security, Learning, Cognition, Mind, Worldview, Success.
Visions of Esmeralda Lock: Epistemic Injustice, ‘The Gypsy Woman’, and Gypsilorism
Authors: Lee Kenneth 
Published: December 2023

Using a combination of Jodie Matthews’ concepts of “The Gypsy Woman” as a product of successive trans-historical encounters (actual, literary, or visual) between Gypsy subject and non-Gypsy audience, formal Archival sources in the Scott MacFie Gypsy Collection at the University of Liverpool, Foucaultian archives of subjugated knowledges, and Miranda Fricker’s approaches to epistemic injustices, this article examines the life-narrative of a Romani woman, Esmeralda Lock, and her changing relationship with her Gypsilorist interlocutors over 70 years of her life. Following the example of Laura Ann Stoler, “factual stories” in Esmeralda’s life that re-affirm Gypsilorist fictions are also examined. Esmeralda was unique in that she was literate, and hence able to leave a small but important trail of correspondence spanning 62 years (including a hitherto unknown sketch and commentary) enabling a challenge to Gypsilorist (mis)representations of her life. Her correspondence also allows her changing epistemic value of Gypsilorists to be traced. Further analyses of epistemic injustices may offer new dimensions to understanding and explaining not just the construction of subordinating discourses, but also the mechanisms of Romani epistemic suppression.

Effect of taping on posture of thoracic region in patients with thoracic kyphosis using acceleration
Authors: Liu Yaoyao , Kim Minhee 
Published: December 2023

BACKGROUND: In the working environment of modern society, a poor sitting posture for a prolonged time may lead to abnormal spinal alignment such as thoracic kyphosis (TK). OBJECTIVE: This study aimed to evaluate the efficacy of taping for posture correction of patients with TK, providing theoretical and empirical guidance for clinicians attempting to rectify TK posture. METHODS: The study included 15 subjects aged 30–60 years, all with a TK angle of ⩾ 40∘. Subjects were required to ascend and descend a set of three steps (a low step, high step, and second low step) under three different conditions: without tape assistance, with taping assistance using 20% elongation, and with taping assistance using 40% elongation. A triaxial accelerometer was employed to measure and compare the anterior-posterior (AP), vertical (VT), and medial-lateral (MIL) movements of the thoracic vertebrae in the different conditions. RESULTS: There were no significant differences in the MIL (P= 0.903) or AP (P= 0.114) movements between the no tape assistance and 20% elongation taping conditions. However, a significant difference was found in the VT movement (P= 0.017). Comparing the no assistance condition to the 40% elongation taping condition, no significant changes were noted in the MIL movement (P= 0.650), but significant differences were detected in both the VT (P= 0.003) and AP movements (P= 0.016). No significant differences were found in any of the three measurements between 20% and 40% elongation taping. CONCLUSION: Taping serves as an effective method for immediately improving kyphotic posture. It corrects the position of the scapula and cervicothoracic line and exerts passive retraction on the relevant muscles, thus mitigating trunk imbalance.
Policy-Based Water Management Challenges at the Local Level Under Non-traditional Security Perspective: The Case of Hanoi City, Vietnam
Authors: Hoang Phi Dinh , Tran Nguyet , Nguyen Ky Xuan 
Published: December 2023

This study identifies water security (WS) management challenges at the local level with the case study of Hanoi, Vietnam, in 2020 - 2022. We apply an interdisciplinary approach of “Management of Non-traditional Security” and “systems thinking”. Particularly, it is inspired by the concept of Cost and Benefit Analysis and integrates the concept of WS (UN-Water), integrated water resources management (Global Water Partnership), and UN Sustainable Development Goal 6 on water. On this basis, the methodological framework is elaborated by an equation reflecting a cause-and-effect relationship between variables of WS state (\(∑_{i=1}^3 S_i\) including safety, stability, sustainability) and WS management costs (\(∑_{i=1}^3 C_i\) including risk, crisis, post-crisis recovery). These variables are assessed semi-quantitatively through six dimensions (technical, policy & legislation, social, economic, awareness & behavior, projects & programs) and measured by interval scale based on a 5-point Likert scale ranging from lowest (0-1.5) to highest (4.6-5) levels. The results show that WS management in Hanoi is ineffective with a very low level of WS state (\(∑_{i=1}^3 S_i\)= 1.86), characterized by water ecosystem degradation, insecure domestic water supply, and an overloading drainage system. If Hanoi’s authorities do not increase investment in WS risk management, its WS state will be worse, and the city will not be able to achieve its sustainable development goals for 2030 and beyond. This approach offers a better understanding of assessing the effectiveness of policy-based WS management under multidimensional aspects of non-traditional security issues, particularly at the local level of emerging countries like Vietnam. The findings contribute to a new way of thinking and a novel philosophy of the WS management system for data-driven policy-making and interdisciplinary water management research.

Published: December 2023

Introduction: To reduce greenhouse gases, the Kigali Amendment to the Montreal Protocol seeks a phasedown of hydrofluorocarbons. R134a alternatives were analyzed for use in a water-cooled chiller: R450A, R513A, R516A, R1234ze (E), R515A, and R515B.Methods: A thermodynamic model of the chiller was employed to calculate compressor power, an input to the life cycle climate performance (LCCP) framework to estimate total equivalent carbon dioxide emissions, CO2eq. Emissions were calculated for an 809 kW [230 Tons of refrigeration (RT) nameplate] water-cooled centrifugal chiller at constant cooling capacity using five power sources (i.e., coal, distillate fuel oil, natural gas, nuclear, and wind) for a median chiller lifetime of 27 years. Two chiller operating profiles were considered: one using operational data from a university campus and a second from literature based on the Atlantic Fleet operation.Results and discussion: When powered via fossil fuels, over 90% of emissions were due to the indirect emissions from energy; therefore, the global warming potential (GWP) of the refrigerant was not the primary contributor to the total CO2eq emissions. With natural gas, total LCCP emissions were reduced for R450A (7.8%), R513A (4.7%), R516A (9.4%), R1234ze (E) (10%), R515A (8.4%), and R515B (6.4%) compared to R134a for the university campus load profile. For the round-the-clock Atlantic Fleet profile, there were emission reductions for R450A (3.6%), R513A (0.25%), R516A (2.3%), R1234ze (E) (2.4%), R515A (1.5%) and R515B (2.4%) compared to R134a. When coupled with renewable energy, the indirect emissions from the chillers substantially decreased, and GWP-dependent leakage emissions accounted for up to 74% or 40% of emissions from R134a alternatives powered by wind and nuclear, respectively. For operation using the load profile from the university campus chillers, R450A had the highest coefficient of performance (COP) of 5.802, while R513A had the lowest COP (5.606). Tradeoffs between alternative refrigerants exist in terms of operation, temperature glide, size of heat exchangers, system design, flammability, cost, availability, and material compatibility. In terms of flammability, R134a, R513A, R450A, R515B and R515A are A1 (nonflammable) fluids. R450A and R516A also have temperature glides of 0.4 K and 0.056 K, respectively, which can affect condenser design. In terms of equipment modification (sizing), R513A require fewer modifications.
