Authors: Głowacka Mariola , Dykowska Grażyna , Gasik Monika , Humańska Marzena , Cybulski Mateusz
Published: April 2024

Background: Satisfaction with life is considered the best indicator of the quality of life of older people and is commonly used as an indicator of adaptation and successful aging. The objective of this study is to evaluate the quality of life and health among pre-seniors and seniors in Płock, Poland, focusing specifically on the interplay between life satisfaction and health outcomes. Methods: The study encompassed a total of 2040 individuals, categorized as pre-seniors and seniors. A diagnostic survey method was employed, utilizing a questionnaire that gathered sociodemographic data and incorporated two standardized psychometric scales: the Satisfaction with Life Scale (SWLS) and the Health Behaviours Inventory (HBI). Results: A majority of respondents demonstrated high levels of life satisfaction, with 1272 people (62.4%) scoring in the high range. In contrast, a smaller group, consisting of 299 respondents (14.7%), reported low satisfaction levels. Notably, men exhibited higher life satisfaction than women (p < 0.001). Additionally, a statistically significant but low correlation was found between the age of respondents and various aspects of the health behaviour index. This includes preventive behaviours (p < 0.001, r = 0.105), health practices (p < 0.001, r = 0.243), proper eating habits (p = 0.004, r = 0.063), and a positive mental attitude (p < 0.001, r = 0.098). These findings underline the complex interplay between age, life satisfaction, and health behaviours among the senior population. Conclusions: High life satisfaction and average to high levels of health behaviours were observed in our study, varying with gender and age. Individuals aged 61–75 reported the highest life satisfaction, whereas those aged 76–90 exhibited the most robust health behaviours. These results underscore the need for age- and gender-specific health policies and programs supporting sustainable aging, aligning with the Sustainable Development Goals. Further national research is essential to comprehensively explore these trends and support global well-being initiatives for aging populations.
Analysis of Transportation Systems for Colonies on Mars
Authors: de Curtò J. , de Zarzà I.
Published: April 2024

The colonization of Mars poses unprecedented challenges in developing sustainable and efficient transportation systems to support inter-settlement connectivity and resource distribution. This study conducts a comprehensive evaluation of two proposed transportation systems for Martian colonies: a ground-based magnetically levitated (maglev) train and a low-orbital spaceplane. Through simulation models, we assess the energy consumption, operational and construction costs, and environmental impacts of each system. Monte Carlo simulations further provide insights into the cost variability and financial risk associated with each option over a decade. Our findings reveal that while the spaceplane system offers lower average costs and reduced financial risk, the maglev train boasts greater scalability and potential for integration with Martian infrastructural development. The maglev system, despite its higher initial cost, emerges as a strategic asset for long-term colony expansion and sustainability, highlighting the need for balanced investment in transportation technologies that align with the goals of Martian colonization. Further extending our exploration, this study introduces advanced analysis of alternative transportation technologies, including hyperloop systems, drones, and rovers, incorporating dynamic environmental modeling of Mars and reinforcement learning for autonomous navigation. In an effort to enhance the realism and complexity of our navigation simulation of Mars, we introduce several significant improvements. These enhancements focus on the inclusion of dynamic atmospheric conditions, the simulation of terrain-specific obstacles such as craters and rocks, and the introduction of a swarm intelligence approach for navigating multiple drones simultaneously. This analysis serves as a foundational framework for future research and strategic planning in Martian transportation infrastructure.
The Relation between Infants’ Manual Lateralization and Their Performance of Object Manipulation and Tool Use
Authors: Babik Iryna , Llamas Kylie , Michel George F.
Published: April 2024

Previous research yielded inconsistent findings regarding whether manual lateralization (e.g., a distinct and consistent hand preference) affects manual performance during infancy and early childhood. The aim of the current study was to determine whether manual lateralization, viewed as a marker of hemispheric lateralization, is associated with infants’ performance in role-differentiated bimanual manipulation (RDBM) and tool use. This longitudinal study assessed 158 typically developing infants (91 males, aged 9.13 ± 0.15 months at baseline) monthly during the 9–14-month period. Developmental trajectories for manual lateralization in object acquisition were related to those for RDBM and tool use, even after accounting for potential sex differences. All statistical analyses were conducted using Hierarchical Linear Modeling software (version 6). Advanced RDBM performance was associated with a lower magnitude of manual lateralization and a higher tendency among infants to use both hands for object acquisition. No significant relation was found between the magnitude of manual lateralization and tool-use performance. Thus, the current results highlight the importance of hand coupling for enhanced RDBM performance. Moreover, across all ages, females outperformed males in sophisticated RDBMs, possibly due to their less pronounced manual lateralization and a greater inclination towards bimanual object acquisition—factors that appear to facilitate RDBM performance.

The article presents the data on the effect of vibration disease caused by exposure to local vibration on the state of male sexual function. The presence of erectile function in subjects with vibration disease, depending on its severity, is shown, which indicates the role of local vibration in the formation of erectile function and raises the problem of early prevention and timely treatment of identified disorders. Interaction disturbances in the hypothalamic-pituitary-gonadal system were identified in men with vibration disease caused by exposure to local vibration. Mandatory periodic medical examinations of enterprise employees whose work involves exposure to local vibra tion should be carried out once every 5 years at the occupational pathology center of a constituent entity of the Russian Federation (according to Order of the Ministry of Health of Russia No. 29n dated January 28, 2021). When conducting such medical examinations, we recommend involving neurologists and urologists-andrologists and expanding the list of instrumental research methods to include methods for assessing erectile function.
Improving approaches to product quality management at large manufacturing enterprises.
Authors:   MBA in Strategic Development, Russia, St. Petersburg, Dovgal D. A.
Published: April 2024

Dynamic conditions of the market environment force companies to seek and apply more progressive methods of quality management. While small companies are more flexible and can quickly adapt to new challenges, large enterprises find it more difficult to change their approaches due to the large number of internal standards, approval parties, and the degree of influence of quality standards on production operations. A reasonable combination of QMS approaches according to the ISO:9001:2015 standard and Lean principles improves the situation and helps improve production quality. However, in the conditions of modern competition, when production deadlines have a direct correlation with the financial wellbeing of the company, there is a need to introduce more modern, adaptive management technologies, for example, to make a transition to project management models even in such conservative areas as shipbuilding and construction. In this context, managing departments responsible for quality requires the manager not only to know the basic principles of forming and using project teams, but also to have the skills to apply these methods. The focus is gradually shifting towards “soft skills”, since the project management methodology, at its core, implies the correct distribution of roles between participants, identifying their strengths, which in turn is the result of a reasonable and professional approach to searching and hiring employees. Mental qualities and way of thinking prevail over applied knowledge and are more valuable for the leader and the company. This article analyzes the problems and challenges facing managers and the reasons for the decline in the overall quality level of large companies. In addition, the article provides practical examples indicating tools for improving the quality management system and describes the economic effect of introducing these tools.

Authors: Hernández-Rodríguez María Guadalupe
Published: April 2024

Microplastics are very small plastic particles, less than
5mm in diameter. These materials may originate from the
degradation of larger plastic products, such as bottles and
bags, or may be intentionally manufactured for use in
cosmetics. Microplastics are a significant environmental
problem because they can be ingested by marine animals
and other living things, causing them significant damage.
Furthermore, these materials can act as toxic
contaminants. The objective of this study is to know and
understand the negative effects of microplastics on
ecosystems, and on human health, and to know the
technologies that are being used to reduce this type of
contamination through recycling and the development of
alternatives to plastic, as well as knowing the policies that
are being developed to address this problem. This study
seeks to create greater public awareness of the problem,
improve understanding of the effects on ecosystems, and
identify the sources and routes of entry of microplastics
into the environment. In summary, research on
microplastics is essential to address the problem of plastic
pollution and to find effective solutions to protect our
environment and health.
Automatic identification of false opinions in social networks
Authors: Guzman-Cabrera Rafael
Published: April 2024

This paper presents the problem of detecting false opinions
in social networks, also called "opinion spam", describing
how lies can be automatically detected using different
methods. It has been shown that deception is frequently
present in everyday communication in social networks.
Deception detection is a well-known challenging problem
in any research area, basically because the human ability
to detect deception is deficient. Particular studies on social
psychology and communications show that the accuracy
rates of people's abilities to detect deception are in the
range of 55 to 58%, i.e., slightly better than chance. This
paper addresses the specific problem of deception
detection in communication. Emphasis is placed on those
approaches that use affective resources such as categorical
and psychometric information provided by natural
language processing tools. Finally, we focus on the
identification of opinion spam, whose detection is very
important for reliable opinion mining. Results obtained
using different machine learning methods are presented.
The results obtained allow us to see the feasibility of the
proposed methodology to carry out the detection of false
opinions in social networks by obtaining accuracy values
higher than 80%.

sized businesses
Authors: Zavala-Huerta Alejandro
Published: April 2024

E-commerce has transformed sales strategies, providing
various options for small and medium-sized enterprises
(SMEs). The surge of e-commerce has posed significant
challenges for SMEs, especially due to the rise of massive
sellers during the COVID-19 crisis. This research stems
from the need to understand how SMEs can implement ecommerce strategies effectively and profitably. The
objective is to analyze key factors such as costs, product
variety, user experience, brand positioning, and reputation,
to offer strong recommendations to SMEs in their choice
of digital sales channels. This study compares three ecommerce channels: online stores, social media, and
marketplaces. A detailed review of existing literature and
an exploratory analysis evaluating different key factors
was conducted. Specific criteria are used to compare and
contrast these options. Some of the results suggest that
online stores and social media offer greater control and
customization, although they entail initial costs and
constant development. Marketplaces, while optimizing
sales, can limit brand customization and reputation. The
findings suggest evaluating the objectives and needs of the
SME before choosing an e-commerce channel.

Effect of dye on the efficiency of Grätzel cells
Authors: Bernal-Martínez Guillermo
Published: April 2024

Renewable energies are playing a critical role in reducing
emissions in the energy generation sector. Photovoltaic
technologies have reduced their cost due to the
improvements in conversion efficiency, the cost of the
materials, the economies of scale, and the investments
made in research and development in the private and
public sectors. The Grätzel cells are part of the third
generation of photovoltaics. This generation of
photovoltaics looks to achieve photovoltaic devices with
great efficiency while keeping low costs using thin layer
processes and non-toxic materials. One of the main
features of these solar cells, also known as dye-sensitized
solar cells (DSSCs), is that the spectrum of absorbed light
depends on the dye used and can be tuned, which have a
big effect on the performance of the cell. This feature
grants this device great versatility, which gives this
technology a great potential to give energy to devices in
indoor illumination and as Building Integrated
Photovoltaics (BIPV). The relevance and working
principle of the Grätzel cells are presented in this text, as
well as the steps that were required to build these solar
cells in a laboratory setting.
