Published: December 2023

This study aimed to evaluate the test-retest reliability of a sprint performance test with semi-tethered front crawl swimming to indirectly assess the current potential to perform at maximal anaerobic effort in adolescent swimmers. Eight adolescent swimmers participated in this study (gender: females (n = 4) aged 13.0 ± 0.8 years, body height 1.6 ± 0.0 m, body mass 50.1 ± 4.5 kg; and males (n = 4) aged 13.3 ± 1.3 years, body height 1.7 ± 0.1 m, body mass 59.0 ± 8.2 kg. The testing protocol consisted of two trials of 25 m semi-tethered front crawl swimming with maximal effort and with 1 kg resisted isotonic load. Velocity data were recorded automatically by the 1080 Sprint device for 15 m (between 3 m and 18 m). The Fast Fourier Transform algorithm filtered raw instantaneous swimming velocity data in distance (time) function. A third-degree polynomial was used to extract the individual velocity profile, from which the following variables were chosen for test-retest reliability and the assessment of sprint performance: ttrial15, vmax, vmin, tvto max, tvat max, Dto vmax, Dat vmax, fatigue index. Parameters such as vmax, vmin, and ttrial15 were estimated from swimming velocity profiles and considered as reliable. The CV showed low variance &lt;5%; while ICC2,1 demonstrated respectively good (ICC2,1: 0.88), very good (ICC2,1: 0.95), and excellent (ICC2,1: 0.98) rate of relative reliability; and the Bland-Altman index revealed an acceptable agreement (LoA ≤5%) between two measurements. The sprint performance test based on semi-tethered front crawl swimming confirmed that ttrial15, vmax, and vmin were reliable variables to indirectly indicate a potential to perform the maximal anaerobic effort among adolescent swimmers. The evaluation of the swimming velocity profiles allows coaches to monitor the adaptive changes of performance during the training process.

Published: December 2023

BackgroundThis study describes a method whose aim is to help companies assess the chemical occupational risks related to labeled products and industrial chemical emissions. The method is intended to be used by industrial hygienists at the scale of one company. Both inhalation and cutaneous exposure routes are taken into account.MethodsThe method relies on a control-banding scheme. A work situation is described by exposure parameters such as the process or the local exhaust ventilation and by the hazard of the product. Each possible value of the parameters is associated with a “band,” which is associated with an integer value. The multiplication of these values results in a score, which represents a priority for intervention. The higher the score, the more the situation warrants investigation for implementing prevention measures, such as chemical substitution and the addition of local exhaust ventilation. To simplify communication, the priority is associated with a colored priority band: red for “very high priority,” orange for “high priority,” and green for “moderate priority.” The priority bands are computed for all work situations performed in a company.ResultsAn example of the use of this method is described in a French façade insulation company.ConclusionA tool named Seirich was developed to implement this method and promote good practices for helping industrial hygienists in the prioritization of interventions for reducing chemical risk in France.

Authors: Uyar Betul , Donmezdil Suleyman 
Published: December 2023

ObjectiveThe aim of this study was to investigate the obsessive-compulsive and depressive symptoms of healthcare workers in a case-control setting as longitudinal.MethodIn this study included 49 healthcare workers and 47 non-health workers. A sociodemographic data form, the Maudsley Obsessive-Compulsive Inventory (MOCI), the Symptom Checklist-90 (SCL-90), and the Hamilton Depression Rating Scale (HAM-D) were used to assess individuals between June 1, 2020 and June 30, 2021. We assessed the same healthcare workers after 12 months on June 30, 2021 using MOCI, HAM-D, and SCL-90.ResultsMOCI and SCL-90 obsessive-compulsive subscale scores were significantly higher in the healthcare workers than in the non-health workers. When we assessed MOCI, HAM-D, and SCL-90 obsessive-compulsive subscale scores after 12 months, there was a statistically significant decrease in the scores of all three scales among the healthcare workers.ConclusionThe results of the study showed that healthcare workers were more likely to have obsessive-compulsive symptoms than non-health workers in the early part of the pandemic on June 1, 2020, as shown by their scores on MOCI and the obsessive-compulsive subscale of SCL-90. When we assessed the same participants after 12 months (June 30, 2021), both MOCI and SCL-90 obsessive-compulsive subscale scores had decreased significantly. In contrast to these results, HAM-D scores significantly increased.
Factors Influencing Alcohol Consumption in Russia
Authors: Sadykova E. A. 
Published: December 2023

The main purpose of the study is to determine the differences in factors influencing alcohol consumption in Russia (among urban and rural residents).The first part of the article provides the author's assessment of studies in which place of residence is considered as a specific factor influencing alcohol consumption. Attention is paid to works that focus on differences in factors affecting alcohol consumption depending on the place of residence.The main section of the article contains a description of the empirical testing of the hypotheses based on statistical data for 2012–2021 from the Russian Longitudinal Monitoring Survey (RLMS) NRU HSE. The author used panel logistic regression with random individual effects for the probability of alcohol consumption and a panel Tobin model for the volume of alcohol consumption. The study revealed differences in the degree of influence of the level of education and religiosity, marital status and the presence of children on the level of alcohol consumption among urban and rural residents. Thus, a higher level of religiosity reduces the likelihood of alcohol consumption by rural residents; the volume of alcohol consumption decreases with a rise in the level of religiosity in the city. It is also shown that the presence of children in families reduces per capita alcohol consumption only in villages.According to the author, the findings help make more effective and targeted recommendations for implementing state alcohol policy.

Published: December 2023

With the rapid spread of technology, consumers spend most of their free time on computers, smartphones, and social networks. It is becoming increasingly difficult for businesses to reach the consumer directly, and more and more businesses are reorganizing all or part of the electronic space. This process was particularly evident during the COVID-19 pandemic. Merchants are discovering ever new ways to present their goods and services. Thus, the changing needs of the user also change the means of promotion. However, the question constantly arises, what factors influence one or another consumer's choice, what increases the brand awareness, how to promote it most effectively on social networks?
We carried out a systematic and comparative analysis of the concepts published in the scientific literature, a study of the brand, brand awareness, brand promotion concepts, and factors increasing brand awareness.
The article aims to identify the factors that increase brand awareness and, based on the results of the Eye-tracking system research, to make suggestions for increasing brand awareness on social networks.
Research methods: a systematic and comparative analysis of concepts and methods published in the scientific literature, statistical processing, expert survey, research of the Eye-tracking system, multicriteria evaluation
Quantitative Evaluation of Assessment Items of the Technology Audit Method for Research and Technology Organisations (RTOs)
Authors: Hecklau Fabian 
Published: December 2023

Applied research and development (R&D) organisations strive to develop technological solutions that translate results from research and science into state-of-the-art products and services. As advanced technological capability is essential to their competitiveness, they need to be able to analyse and evaluate their technological capabilities. Hence, a tool or method is required that objectively and practically assesses the technological capability of Research and Technology Organisations (RTOs) while meeting their unique requirements. The technology audit enables the assessment of the technological capability and thus the technological maturity of an RTO. It focuses on the analysis of the research activities in the R&D service areas of the RTO. This allows for a comprehensive understanding of the technologies used, the research competencies, the technologies developed, and the established technology partnerships of the RTO. In this context of the development of a suitable technology audit methodology, this paper aims to describe the process of validation of assessment items for evaluating the technological maturity of applied R&D organisations. After a brief overview of the technology audit method and the assessment dimensions and items, the focus is placed on the process of its validation. An expert survey using a questionnaire was created and used to evaluate the relevance of the 11 assessment items for the technology audit instrument in the three dimensions of Technology Base, Products & Services and Cooperation, as well as the respective aspects within each assessment item. This evaluation is intended to validate the selection of the items and to specify their respective importance to ultimately optimise the process of auditing applied R&D organisations.
Direct Synthesis of Far-Field Patterns
Authors: Xiao Gaobiao 
Published: December 2023

I feel sorry that the manuscript is written in a hurry and most content
of the synthesis of the linear arrays is similar to that discussed
in C.A. Balanis book as pointed out by reviewers. However, I still post
this manuscript on this server as I indeed derived it from the very
beginning and I wish some part of them may be of usage for others,
especially the 2-D cases and some of my considerations on this issue.
The direct synthesis results are very good initial values for further
optimization with a method in which the properties of the entire
functions and the number of degrees of the freedom of far fields are
made full use of.

In this paper, the current distribution is expanded with Fourier series.
Analysis shows that only a limited number of the harmonic components of
the current can generate propagation fields and contribute to the
far-field pattern. Most importantly, it is found that this part of the
current can be directly obtained from the far-field without utilizing
any optimization algorithm. The degree of freedom of the far-field can
be exactly counted for a linear source or a rectangular planar source.
Numerical examples verify that the method is very efficient for
synthesizing large antenna arrays.
Explicit and Implicit Integration of Constitutive Equations of Chaboche Isotropic-Kinematic Hardening Material Model
Authors: Skrzat Andrzej , Wójcik Marta 
Published: December 2023

The proper selection of the material model and its parameters in numerical simulations of the material response under loading is a very important task. In the cyclic load one should assume different phenomena, e.g. ratchetting effect, the mean stress relaxation, creep, etc. The Chaboche kinematic hardening model is mainly applied in order to capture the Bauschinger effect due to its good description of the material behaviour under the cyclic loading. The modified Chaboche isotropic-kinematic hardening model is considered in this paper in order to simulate the strain-controlled and stress-controlled uniaxial cyclic tension-compression test. The implicit and explicit integration procedures are tested here, showing advantages and disadvantages of both methods. It is shown that both approaches provide similar results. The implicit integration method of constitutive equations is unconditionally stable and thus less calculation steps are required in comparison to the explicit procedure. The implicit and explicit integration of the Chaboche model including isotropic and kinematic hardening are then implemented for the 3D case in commercial ABAQUS program in the form of the user material procedure. The correctness of results obtained for the user material model is verified by comparison to results for commercially implemented Chaboche model.
PROPOSALS FOR MATHEMATICAL SUPPORT OF DECISION-MAKING ON APPLICATION OF UNMANNED AIRCRAFT SYSTEMS FOR EXTINGUISHING FIRES IN HIGH-RISE BUILDINGS

Published: December 2023

Рассмотрены вопросы применения беспилотных авиационных систем (БАС) при тушении пожаров в зданиях повышенной этажности в условиях плотной городской застройки. Целесообразность такого использования БАС обусловлена определенными трудностями работы пожарных внутри горящего здания, а при наружном пожаротушении – еще и риском для их жизни на уровне верхних этажей. Даны предложения по математическому обеспечению принятия руководителем тушения пожара в высотном здании решения о применении БАС в качестве мобильного средства доставки огнетушащих веществ в очаг пожара.
The article is devoted to issues related to application of unmanned aircraft systems (UAS) for extinguishing fires in high-rise buildings in conditions of dense urban development. In particular, the article presents proposals for the mathematical support of the decision of the fire manager to use a fire-fighting UAS as a mobile means of delivering extinguishing agents to the ignition source in high-rise building. The expediency of application of fire-fighting UAS is due to certain difficulties of firefighters working inside a burning building, and in case of external firefighting, also due to the risk to their lives at the level of the upper floors. The relevance of the topic is explained by the existing discrepancy between the required degree of validity of the decision to use fire-fighting UAS, on the one hand, and the insufficient capabilities of existing methods to ensure the efficiency of assessing the specific situation, on the other. Thus, the effectiveness of the use of UAS is achieved only under certain conditions, and the identification of these conditions is carried out using analytical methods that require complex calculations. This circumstance will contribute to the fact that the fire manager will not be able to determine in a timely manner the rational place of application of the firefighting UAS and will make an erroneous decision. Thus, a situation may arise in which, when the fire brigades of the corresponding UAS enter service, even with very satisfactory characteristics, fire extinguishing in high-rise buildings will be ineffective when using them. The authors of the article believe that the rational solution to the stated problem is the application of electronic computing equipment with appropriate software by the fire manager. The features of creation of software designed to support decision-making on the use of UAS as mobile means for delivering of extinguishing agents to a fire in high-rise buildings are discussed in this article.

Abstract
The impact of the Double Asteroid Redirection Test spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos’s orbit substantially, largely from the ejection of material. We present results from 12 Earth-based facilities involved in a world-wide campaign to monitor the brightness and morphology of the ejecta in the first 35 days after impact. After an initial brightening of ∼1.4 mag, we find consistent dimming rates of 0.11–0.12 mag day−1 in the first week, and 0.08–0.09 mag day−1 over the entire study period. The system returned to its pre-impact brightness 24.3–25.3 days after impact though the primary ejecta tail remained. The dimming paused briefly eight days after impact, near in time to the appearance of the second tail. This was likely due to a secondary release of material after re-impact of a boulder released in the initial impact, though movement of the primary ejecta through the aperture likely played a role.

Published: December 2023

Osteoarthritis (OA) is characterized by degenerative articular cartilage. Nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) plays an important role in inflammation. This study aims to investigate whether protective effects of curculigoside on OA are medicated by the regulation of NLRP3 pathway. Destabilization of the medial meniscus (DMM) was performed to build an OA mouse model. After surgery, OA mice were treated with curculigoside. Immunohistochemistry was conducted to evaluate OA cartilage. In addition, human chondrocytes were isolated and treated with curculigoside. The mRNA and protein expression of iNOS, MMP-9, NLRP3 was detected by PCR and Western blot analysis. Curculigoside inhibited mRNA and protein levels of iNOS and MMP-9 induced by DMM surgery in a dose-dependent manner. Furthermore, the expression of NLRP3, NF-κB and PKR was downregulated after curculigoside administration. Moreover, curculigoside reversed the effects of IL-1β on MMP-9, iNOS and type II collagen expression at mRNA and protein levels in human chondrocytes in a dose-dependent manner. In conclusion, curculigoside exhibits beneficial effect on cartilage via the inhibition of NLRP3 pathway.
Intensive follow-up vs conventional follow-up for patients with non-metastatic colorectal cancer treated with curative intent: A meta-analysis
Authors: Cui Li-Li , Cui Shi-Qi , Qu Zhong , Ren Zhen-Qing 
Published: December 2023

BACKGROUND
The frequency and content of follow-up strategies remain controversial for colorectal cancer (CRC), and scheduled follow-ups have limited value.
AIM
To compare intensive and conventional follow-up strategies for the prognosis of non-metastatic CRC treated with curative intent using a meta-analysis.
METHODS
PubMed, Embase, and the Cochrane Library databases were systematically searched for potentially eligible randomized controlled trials (RCTs) from inception until April 2023. The Cochrane risk of bias was used to assess the methodological quality of the included studies. The hazard ratio, relative risk, and 95% confidence interval were used to calculate survival and categorical data, and pooled analyses were performed using the random-effects model. Additional exploratory analyses were performed for sensitivity, subgroups, and publication bias.
RESULTS
Eighteen RCTs involving 8533 patients with CRC were selected for the final analysis. Intensive follow-up may be superior to conventional follow-up in improving overall survival, but this difference was not statistically significant. Moreover, intensive follow-up was associated with an increased incidence of salvage surgery compared to conventional follow-up. In addition, there was no significant difference in the risk of recurrence between intensive and conventional follow-up strategies, whereas intensive follow-up was associated with a reduced risk of interval recurrence compared to conventional follow-up. Finally, the effects of intensive and conventional follow-up strategies differed when stratified by tumor location and follow-up duration.
CONCLUSION
Intensive follow-up may have a beneficial effect on the overall survival of patients with non-metastatic CRC treated with curative intent.

Published: December 2023

Biofilms are a common cause of nosocomial infections that often attack hospitalized patients. The main objective of this study was to examine the efficacy of silver nanoparticles-temu giring rhizomes in combating bacteria and preventing biofilm formation. The antibacterial and antibiofilm properties of these nanoparticles were evaluated against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The research began with the extraction of temu giring rhizome, synthesis of silver nanoparticles-temu giring rhizome, disk diffusion test, biofilm formation inhibitory activity test, and characterization of silver nanoparticles-temu giring rhizome. In this research, silver nanoparticles-temu giring rhizome were utilized at concentrations of 10, 20, 40, 80, 160 μg/ml, and a control in the form of chlorhexidine. The results showed that the silver nanoparticles-temu giring rhizome produced a larger inhibition zone for bacterial growth compared to the control against the three bacteria. The IC50 value of silver nanoparticles-temu giring rhizome required to inhibit biofilm formation was 27.64 μg/ml in E. coli, 29.29 μg/ml in P. aeruginosa, and 26.21 μg/ml in S. aureus. In P. aeruginosa, E. coli, and S. aureus, the IC50 for preventing biofilm formation by silver nanoparticles-temu giring rhizome was determined to be 27.64 μg/ml, 29.29 μg/ml, and 26.21 μg/ml, respectively. Evaluation of silver nanoparticles revealed the success of temu giring rhizomes in reducing silver ions. This is shown that silver nanoparticles-temu giring rhizomes can be developed into active ingredients that inhibit the growth of bacteria that cause nosocomial infections.
