Abstract

OBJECTIVES:
Delivering chest compressions (CCs) at the targeted depth and rate is a crucial aspect of maintaining the quality of cardiopulmonary resuscitation (CPR). Although administering CCs on a firm surface is recommended, it may not always be feasible. This study aimed to determine whether the underlying surface affects CC depth and rate using a real-time feedback device.

METHODS:
An observational study was conducted on a manikin (ResusciAnne; Laerdal). 25 volunteer emergency medicine physicians performed 2 min of continuous CCs without feedback on the floor, emergency department stretcher (EDS), and ambulance stretcher (AS). The following day, all participants performed an additional 2 min of CCs while receiving audiovisual real-time feedback (ZOLL M2 series). Compression depths and rates were measured and recorded in a real-time feedback device.

RESULTS:
A total of 150 CC intervals were analyzed. The mean values of compression depths and rates on all surfaces are within the targeted range for high-quality CPR, except for the mean depth without feedback on the EDS (mean: 6.37 cm). There were a statistically significant difference, with both AS and EDS were achieved deeper compressions than those on the floor (P < 0.05). When examining the mean compression depths on three different surfaces with feedback, no statistically significant difference was observed. However, CCs performed without feedback on both AS and EDS were statistically significantly deeper than those on the floor. The mean compression rates both on the floor and the AS were statistically significantly faster compared to EDS. When examining the mean compression rates during CCs performed on three different surfaces with feedback, no statistically significant difference was observed but in the without feedback compressions, both on AS and floor were found to be statistically significantly faster than EDS.

CONCLUSIONS:
CC’s depth are influenced by the underlying surface. It appears more feasible to minimize surface-related differences while maintaining appropriate targets for depth using real-time feedback devices. The mean compression rate could be kept within the targeted range regardless of the surface.
Rigidity of smooth finite-time blow-up for equivariant self-dual Chern–Simons–Schrödinger equation
Authors: Kim Kihyun 
Published: January 2025

We consider the long-time dynamics for the self-dual Chern–Simons–Schrödinger (CSS) equation within equivariant symmetry. The self-dual CSS equation is a self-dual

L^{2}

-critical equation having pseudoconformal invariance and solitons. In this paper, we show that any

m

-equivariant,

m\geq1

,

H^{3}

finite-time blow-up solution to the self-dual CSS equation is a pseudoconformal blow-up solution. More precisely, such a solution decomposes into the sum of one modulated soliton, which contracts at the pseudoconformal rate

\lambda(t)\sim T-t

, and a radiation. Applying the pseudoconformal transform in reverse, we also obtain a refined soliton resolution theorem for

m

-equivariant,

m\geq1

, sufficiently regular and localized solutions: any such solutions blow up in the pseudoconformal regime, scatter (to

0

), or scatter to a modulated soliton with some fixed scale and phase. To our knowledge, this is the first result on the full classification of the dynamics of arbitrary smooth and spatially decaying solutions in the class of nonlinear Schrödinger equations which are not known to be completely integrable. Our analysis not only builds upon the previous works, especially the soliton resolution theorem by the author, Kwon, and Oh, but also refines all steps of the arguments typically employed in the forward construction of blow-up dynamics. The key feature of the proof is that we can identify the singular and regular parts of any

H^{3}

finite-time blow-up solutions, such that the evolution of the singular part is governed by a universal modulation dynamics while the regular part is kept

H^{3}

-bounded even up to the blow-up time. As a byproduct, we also observe that the asymptotic profile has a universal singular structure.
Generalized Erdős–Turán inequalities and stability of energy minimizers
Authors: Shu Ruiwen , Wang Jiuya 
Published: January 2025

The classical Erdős–Turán inequality on the distribution of roots for complex polynomials can be equivalently stated in a potential theoretic formulation, that is, if the logarithmic potential generated by a probability measure on the unit circle is close to

0

, then this probability measure is close to the uniform distribution. We generalize this classical inequality from

d=1

to higher dimensions

d>1

with the class of Riesz potentials which includes the logarithmic potential as a special case. In order to quantify how close a probability measure is to the uniform distribution in a general space, we use Wasserstein-infinity distance as a canonical extension of the concept of discrepancy. Then we give a compact description of this distance. Then for every dimension

d

, we prove inequalities bounding the Wasserstein-infinity distance between a probability measure

\rho

and the uniform distribution by the

L^{p}

-norm of the Riesz potentials generated by

\rho

. Our inequalities are proven to be sharp up to the constants for singular Riesz potentials. Our results indicate that the phenomenon discovered by Erdős and Turán about polynomials is much more universal than it seems. Finally, we apply these inequalities to prove stability theorems for energy minimizers, which provides a complementary perspective on the recent construction of energy minimizers with clustering behavior.

Authors: Selvaraj Girish , Ramasamy Palanivelu , Pavul Jegan 
Published: January 2025

Objective: This study aims to understand what drives people in India to purchase organic food, focusing on factors like health benefits, social influences, and practical value. It seeks to uncover how these elements shape consumer intentions and behavior.

Theoretical Framework: The research is guided by theories of consumer behavior, especially the Theory of Planned Behavior (TPB), which examines how attitudes, societal expectations, and perceived control influence decisions. Key concepts like health awareness, social pressure, and product value form the foundation for this exploration.

Method: A survey-based quantitative approach was used to collect data from Indian consumers with varying levels of familiarity with organic food. Participants responded to a structured questionnaire, which was validated for consistency (Cronbach’s Alpha = 0.912). The data were analyzed using reliability tests, descriptive statistics, and correlation studies.

Results and Discussion: The findings show that health benefits and social norms strongly influence organic food purchase intentions. Consumers generally view organic food as high-quality and good for health, but opinions on its safety and social status are mixed. Limited availability and convenience emerged as key challenges. These insights are examined in light of existing theories, along with the study’s limitations.

Research Implications: This study offers valuable guidance for policymakers, retailers, and producers to boost organic food adoption by improving accessibility, emphasizing health benefits, and leveraging social influence through marketing.

Originality/Value: Focusing on the Indian market, this research sheds new light on consumer motivations in an emerging economy, providing actionable strategies to promote organic food consumption.

Authors: Özgürel Gizem , Özsezgin İlknur , Ünal Aydın , Çilesiz Emre 
Published: January 2025

Objectives: The study aims to explore the effects of artificial intelligence (AI) technologies in the tourism sector and assess the potential reflections of these effects on tourists, particularly in the context of the "Dead Internet Theory." It examines how AI, as a technology capable of learning and problem-solving, can enhance customer satisfaction, reduce costs, and optimize business processes within the tourism industry.

Methods: The study utilizes a conceptual analysis of the "Dead Internet Theory" and its implications for the tourism sector. It investigates how AI technologies, which mimic human behavior and thought processes, influence interactions in the digital space, particularly in tourism. The research also evaluates the impact of AI on tourists' purchasing decisions, considering factors such as fake comments, artificial experiences, and algorithmic guidance.

Results: The findings indicate that the "Dead Internet Theory" suggests AI-generated content increasingly dominates the internet, limiting human participation and potentially manipulating digital interactions. In tourism, this can result in tourists being influenced by fake reviews, artificial experiences, and algorithmic recommendations, which may mislead their decisions. Additionally, the perception of fake popularity on social media could distort tourist behavior and negatively affect sustainable tourism practices.

Conclusion: The study concludes that while AI offers significant opportunities to improve customer satisfaction and optimize tourism business processes, it must be used ethically and with consideration for legal issues. To prevent digital manipulation, the research emphasizes the need for balancing AI use with ethical guidelines, promoting the reliability of online reviews, and developing strategies to ensure transparency in algorithmic referrals. Ethical principles and safeguards should be established to mitigate the negative impacts of AI on tourist behavior and support sustainable tourism practices.
Histomorphological Spectrum of Gastric Polyps: A Retrospective Analysis from a Tertiary Care Centre in South India
Authors: Shanker Swathy , Dhanya V , Kunhikannan Sandeep , Menon Mahesh , Sathi P P 
Published: January 2025

Abstract

Introduction: Gastric polyps are often incidentally detected during endoscopic evaluations, with a prevalence of approximately 5% in endoscopy cases. Their diagnosis and classification rely on histopathological examination to determine their nature and potential for malignancy. Common gastric polyps include hyperplastic polyps, fundic gland polyps, and adenomatous polyps. This study aims to evaluate the histopathological spectrum of gastric polyps in a tertiary care setting and document the associated clinical presentations. Materials and Methods: This retrospective observational study was conducted from January 2019 to February 2023 at a tertiary care centre in South India. A total of 124 patients with histopathologically confirmed gastric polyps were included. Patients with known gastric malignancies were excluded. Results: The study population showed a slight female predominance (53.2%). The most common clinical complaint was dyspepsia, reported by 61% of patients. Most patients were in the age group of 51–80 years. Hyperplastic polyps were the most frequently observed type (47.16%), followed by fundic gland polyps (40.65%). The body of the stomach was the most common site of polyp occurrence (47.15%). Conclusion: The findings suggest a predominance of fundic gland polyps in the studied South Indian population. Additionally, Helicobacter pylori infection was detected in more than 45% of hyperplastic polyps, emphasizing its potential role in polyp formation. Routine histopathological evaluation remains crucial for accurate classification and risk assessment of gastric polyps. Further studies are warranted to explore the clinical implications and long-term outcomes of gastric polyp management.
VAE-CNN: Deep Learning on Small Sample Dataset Improves Hydrogen Yield Prediction in Co-gasification
Authors: Vaiyapuri Thavavel , Elashmawi Walaa H. , S Shridevi , Asiedu William 
Published: January 2025

Renewable and ecologically friendly energy sources have piqued the attention of researchers due to the increasing usage of fossil fuels and the looming problem of global warming. One potential solution that might pave the way for sustainable growth is biohydrogen, which could significantly reduce reliance on fossil fuels. The co-gasification process is garnering attention as a promising method for the production of hydrogen from plastic waste and biomass. In this context, optimizing the process is crucial for improving and predicting biohydrogen production. The recent advancements in deep learning models have opened up promising new possibilities. Training these models with small in situ samples, however, results in poor accuracy. Hence, this research is the first of its kind to explore the possibility of using a variational autoencoder (VAE) to provide high-quality synthetic data and aid the identification of process parameters that can improve hydrogen generation in co-gasification. VAE-augmented training set is utilized to guide one-dimensional convolutional neural network (1D-CNN) to accurately capture the relationship between hydrogen production and the process parameters. The efficiency of VAE and 1D-CNN is verified by comprehensive comparison evaluations with different data augmentation (DA) schemes and regression models. The experimental findings demonstrate that the proposed VAE network significantly improves prediction performance by generating data that is more realistic in comparison to other DA schemes. With the synthetic data from VAE, 1D-CNN was able to optimize the co-gasification process for increased hydrogen production, with a 32% improvement in maximum error and a 7% improvement in root mean squared error.

Semantic field of health in the Hispanic toponymic discourse
Authors: Martynenko Irina 
Published: January 2025

Health and medical toponyms are not the most numerous groups in the toponomastics of the world, however, present an important part of the history of a city where they function. The article analyzes the extensive lexical-semantic field of health in Hispanic toponymy of the world in the aspect of its constituting units’ distribution. By means of the GeoNames electronic database, material for the study was selected using the continuous sampling method. The functioning of such units is analyzed from the pragmatic point of view, numerous examples are given. The boundaries of the core and peripheral region of the field are determined. It is established, in particular, that in Paraguay and Uruguay toponyms are associated with the names of outstanding doctors and scientists. And the generalizing concept of Medicina – the Spanish for “medicine” (mainly) – is a component that appears mostly in the urban toponymy. There are also Latin American cities named after diseases. The author comes to the conclusion that the meliorative connotation within this semantic field prevails over the pejorative one. And the linguistic parameters obtained can be viewed as markers of the national identity in toponymy of the indicated regions which are isosemic to the spread of the Spanish language on these terrritories. Parallels are drawn between the semantic field of health, developed by Russian toponymists in the field of regional onomastics, and that in the field of Hispanic toponymy. It is demonstrated that the most abundant Hispanic toponymic unit within the theme of health is Salud which is “health” for Spanish and the core or concept of the considered semantic field. Some place names can be attributed the “health” semantic field only with due caution as they belong to another semantic category. The article contributes to the development of the theory of the semantic field, national identity, toponomastics and linguodidactics.

Published: January 2025

This study assessed the availability and utilization of resources to support AABE programme in Samburu County. AABE was introduced by the Kenya Government, religious entities and non-governmental organizations (NGOs) with the aim of promoting access to basic education and enhancing Universal Primary Education for all (UPE). However, school enrolment and literacy levels in Samburu have been low, at (44%) and (12%) respectively, raising the need to examine the success of AABE in meeting the envisaged purpose. The study tested one hypotheses, namely, resource-input, in Samburu County. The study applied a survey research design and collected data from both primary and secondary sources. Three structured questionnaires were used for 400 learners’ household heads, and 56 teachers in charge of the 56 AABE Centres and 10 AABE providers. Secondary data were obtained from the Ministry of Education offices, AABE Centres, libraries and the internet. A stratified random sampling technique was used to sample the 400 respondents. Data was presented using frequency tabulations, chi-square, multiple regressions and correlation analyses. The findings had (73.4%) of the respondents who stated that Resource-input was inadequate. The respondents gave suggestions that there is need to approach the development in nomadic pastoralists areas from a multi-faceted approach such as addressing the problems of inadequacy of water, medical facilities, infrastructure, livelihoods and the problem of conflicts. The study recommended for more studies to be done on viability of AABE in other nomadic pastoral areas and encompassing other variables.

La fresa (Fragaria x ananassa) es una especie vegetal de gran importancia económica y agroalimentaria, que se cultiva en regiones agroindustriales de México, como el Bajío. El principal insumo de la producción agrícola son las plantas, cuya primera etapa de multiplicación empieza con la formación de clones por cultivo in vitro a partir de las plantas madre seleccionadas. Sin embargo, diversas características de las plantas regeneradas pueden presentar variaciones que reducen su valor agronómico y comercial. Dicha variabilidad es debida a múltiples factores, aunque destaca el efecto que tienen las combinaciones de auxinas y citocininas, así como sus concentraciones. El objetivo del presente estudio fue evaluar las características de plantas de fresa regeneradas in vitro mediante organogénesis directa ante diferentes concentraciones de auxinas y citocininas. Los explantes se obtuvieron de meristemos apicales en los estolones de plantas madre de la variedad Camino Real. Se utilizaron 21 tratamientos de auxinas (AIB y 2,4-D) y citocininas (BAP y cinetina) para evaluar la organogénesis. El mayor número de vitroplantas se obtuvo con la combinación del AIB y el BAP a 0,4 mg·L-1, con una tasa de regeneración promedio de 68,3 %. En dicho tratamiento se presentaron la vitroplantas con mejor desarrollo y alta respuesta antioxidante. La mayor concentración promedio de prolina de 1,7 µg mL-1, en el tratamiento control sin auxinas ni citocininas.
