Effects of CPC 47 (IFRS 15) from the perspective of revenue management in the brazilian stock market
Authors: Dias André Lamblet , Costa Thiago de Abreu
Published: February 2024

This study analyzed the effect of adopting CPC 47 (IFRS 15) for revenue recognition on the quality of accounting information from the perspective of revenue management in the Brazilian stock market. The study sample has a total of 560 observations corresponding to 112 companies from 2016 to 2020. The models by specific discretionary accruals of revenues proposed by Caylor (2010) and Stubben (2010) were considered to measure the management levels. As a method of analysis, we used regression models with panel data and tests at a significance level of 5%. According to the results obtained, it was impossible to confirm that adopting CPC 47 (IFRS 15) affected the quality of accounting information from the increase in revenue management levels, as well as whether the effects on the specific sectors indicated by the literature as more impacted were more significant than the other sectors in the Brazilian capital market. The research is relevant because it advances existing studies by using two different revenue management models to analyze the effects of specific accruals after adopting the standard and, in addition, extends the period and sample of Brazilian companies. Therefore, this research contributes to deepening discussions on the effects of applying accounting standards and assists in the analysis of regulatory bodies, preparers, auditors, and financial information on the effects of the new accounting standard after adoption, especially in the Post-Implementation Review (PIR) process of IFRS15.
Reversão de perdas por Impairment e gerenciamento de resultados
Authors: Souza Vinícius Jesus , Freitas Sheizi Calheira de , Bispo Jorge de Souza
Published: February 2024

O impairment test, embora seja relevante para a qualidade da informação contábil, requer a realização de estimativas subjetivas que permitem discricionariedade à gestão das empresas e abrem margem para o gerenciamento de resultados, sobretudo quando há permissão para que as perdas sejam revertidas. Nesse contexto, esta pesquisa objetivou investigar se existe relação entre as reversões das perdas por impairment evidenciadas pelas empresas brasileiras listadas na B3 e a prática de gerenciamento de resultados entre 2010 e 2019. Para isso, foi realizada uma pesquisa descritiva e quantitativa que testou três hipóteses originalmente desenvolvidas no trabalho de Duh et al. (2009) para analisar se as empresas que mais reconhecem perdas por impairment revertem essas perdas no futuro para evitar a diminuição do resultado contábil e se esse comportamento é mais pronunciado diante de maiores níveis de endividamento ou quando remuneram seus gestores com base no lucro. Os achados revelaram que, embora as empresas que reconheçam mais perdas realizem maiores reversões no futuro, essas reversões não ocorreram em um contexto de declínio do resultado e não foram influenciadas significativamente pelo endividamento e pela sensibilidade da remuneração dos gestores ao lucro. Considerando a escassez de evidências empíricas sobre essa temática no Brasil e a necessidade de se observar esse fenômeno em diferentes ambientes institucionais e regulatórios, espera-se que este trabalho contribua para estimular a realização de outros estudos semelhantes, bem como para fomentar discussões sobre como a possibilidade de reverter as perdas por impairment afeta a qualidade da informação contábil.
The role of investment in the development of industrial enterprises
Authors: Pasheeva T. Yu. , Zverev A. L.
Published: February 2024

Economic regulation of the processes of modernization of industrial production is a fundamental principle of industrial policy. It is noted that investments act as a mechanism that can launch the development of industrial enterprises and allow them to enter a trajectory of accelerated development. Particular attention is focused on current internal and external problems of industrial enterprises and ways to solve them. As an example of the development and implementation of an innovative development strategy under conditions of severe external restrictions, the activities of the limited liability company “Engineering Center for Fire Robotics “EFER” of the Republic of Karelia” are considered. Currently, the EFER Engineering Center occupies a leading position in the development and production of robotic fire extinguishing installations and fire robots in Russia, which could not be achieved without the development of the production base and without maintaining annual R&D costs in the amount of 5÷8% of the cost of production. Using the example of the EFER Engineering Center, the possibility of innovative development of an enterprise is demonstrated, subject to government support and investment. Conclusions are drawn about the need to attract additional finance, which will allow industrial enterprises to enter the trajectory of accelerated development. It is indicated that in order to create a favorable investment climate, an investment strategy is needed that determines the investment priorities of the region. The dynamics of attracted investments depend on the economic climate and investment attractiveness of the regions. The region’s investment strategy should provide for the development of a comprehensive plan that ensures the achievement of the strategic vision and development goals of the region, taking into account the stimulation of innovative industrial growth and the creation of new opportunities for investors. A favorable investment climate will create objective prerequisites for the development of competitive industrial enterprises capable of ensuring the technological sovereignty of the Russian Federation.

Authors: Nevolin A. E. , Cherepovitsyn A. E.
Published: February 2024

The strategic development of mining and metallurgical companies is currently largely related to the development of social policy and maintaining high responsibility of the business towards its employees and ecosystems. The strategic goals of companies should be aimed at the environmental modernization of production, ensuring, among other things, the reduction of emissions of harmful substances and greenhouse gases. The development of low-carbon technologies, compliance with modern environmental requirements, and the achievement of a high level of social responsibility are both areas of strategic development and opportunities for the formation of new competitive advantages. The purpose of the work is to adapt the methods of strategic analysis to modern environmental and social trends to set the current strategic goals of mining and metallurgical companies in terms of increasing attention to the social responsibility of business and the implementation of green production and low-carbon development. The study substantiates the increasing role of environmental and social factors of sustainable development in the activities of mining and metallurgical companies. Using MMC Norilsk Nickel as an example, the main environmental-oriented areas of the company’s development are identified, and the issues of social policy are also reflected. An algorithm of strategic analysis for the specifics of mining and metallurgical companies is proposed, suggesting the use of classical methods of strategic analysis and goal setting with the use of VRIO-analysis methodology, which in turn will allow to identify sustainable competitive advantages associated with the achievement of environmental and climatic objectives and increased social responsibility.
Reorganization of the manufacturing system of engineering enterprises: the emergency period
Authors: Garnov A. P. , Slavyanov A. S.
Published: February 2024

The manufacturing system of the majority of domestic engineering enterprises is built on the basis of long-term contracts with suppliers of the materials and tools, and currently is in an unstable condition. This determines the acuteness of the problem of reorganization of the manufacturing system. To tackle this problem the authors solved the following tasks. The enterprises were classified into groups which possess specific opportunities to adapt to the external environment. The authors identified the basic prerequisites for reorganization of the national manufacturing system among which of great importance are external financial and logistical restrictions, greatly increased demand of the national economy in various complicated technical facilities and spare parts, and the general instability. Withdrawal of foreign investors from the Russian market has created conditions to expand the market share of the domestic companies and increase their output. The authors suppose that the projects on the reorganization of the domestic enterprises of the engineering complex should be based on flexible manufacturing systems capable of integrating into production lines and responding promptly to external influences.

An Official of a Law Enforcement Agency in the Structure of Crime Prevention
Authors: Ivantsov Sergey , Drozdov Denis
Published: February 2024

The problem of the effectiveness of crime prevention in the modern conditions is acquiring the features of a global one. The strategies of counteracting new forms of crime are formed and tested at international and national levels withing the framework of cooperation of different subjects. The technologies adapted for criminal purposes require an adequate reaction from the state in the form of improving criminal policy and reconsidering approaches to crime counteraction, including the use of international experience in combination with specific national features.
Crime prevention is viewed as a process with its own content, which includes a multitude of subjects and objects. The variety of subjects and forms of their interaction gives rise to the necessity of researching their essence and legal status in order to build a system combining optimal ways of influencing these objects. Law enforcement bodies have the greatest potential, they act as specialized subjects carrying out tasks through authorized officials.
Lying outside the scope of research is the unsolved problem of defining subjects responsible for preventing crimes against officials of law enforcement bodies, as shown by the official statistical data of the Russian Federation correlating with data from other countries. They are specialized subjects of crime prevention, and if a crime is committed against them, they lose the status of subjects and become objects in the newly emerged legal relations. This leads to the necessity of singling out a new category of subjects responsible for the prevention of crimes committed against the officials of law enforcement bodies. Their status should be researched on the basis of the current legislation, court practice, and national legal doctrine by singling out the rights, responsibilities, guarantees and liability of such subjects.
Criminal Business of Illicit Trafficking of Cultural Property: Features and Counteraction in Modern Conditions
Authors: Repetskaya Anna
Published: February 2024

The author analyzes the criminal business of illicit trafficking of cultural property in Russia, describes its features, determinants and counteraction to it in modern conditions. The analysis was conducted on the basis of statistical data of different governmental organizations that monitor the condition of counteracting the criminal business in this sphere, as well as the expert assessments of leading Russian companies and specialists who study the situation with illicit trade in cultural property. As this criminal business is of transnational character, foreign sources, both statistical and analytical, were used for a comparative analysis. In addition to the analysis of criminal business, which is immediately connected with the trade in cultural property, the author also assessed the situation in the related criminal market of art forgeries. As a results, the author concludes that illicit trade in cultural property both in Russia and in the world is, on average, about 10 % of the legal trade. Statistical indicators determining the ranges of registered crimes that regulate criminal liability for activities in this sphere demonstrate a decrease in the number of thefts of objects of cultural value, and, simultaneously, an increase in illegal search and appropriation of archeological artifacts from their resting places. At the same time, trafficking of cultural property is decreasing, and only isolated cases of such crimes are registered. The analysis of the features of stolen objects showed that their Russian and global structures differ: while numismatic property and other small objects are the dominant type of goods in the world, Russian trafficking is dominated by icons (60 %). The market of forgeries of cultural property is growing, it is closely connected with the legal market of original cultural property and the market of corrupt service. The key factors determining the development of this segment of criminal market are the following: an increasing demand for objects of cultural value; the appearance of special places for their storage (freeports) with an offshore status; transnational character of criminal activities; use of telecommunication networks for finding and trading goods without identifying the participants of such trade. Counteraction is quite effective due to its well-developed mechanism of legal regulation, as well as the formation of international databases of stolen objects of cultural value, which hinders their legalization, and the use of these data for the creation of digital clones of such objects with the involvement of artificial intelligence in their identification.
Scientific Rationale of the Problem of Female Criminal Behavior
Authors: Kunts Elena
Published: February 2024

When explaining female criminal behavior from the scientific standpoint, researchers study it from different angles — criminological, criminal law and penitentiary. In the current article, the author examines female criminal behavior within the scope of not only anthropological and sociological approaches, by also of the psychological approach aimed at analyzing the causes of deviant behavior that does not correspond to the requirements of laws or social norms. It is noted that the sociological approach to researching female crime is based on taking into account not only quantitative characteristics of the social space, but also the social characteristics of women, which are undergoing a transformation due to a changing role of women in society. The author summarizes modern trends of female crime and notes that it is highly dynamic and thus leading to a considerable gap between the practice of counteracting female criminal behavior which is due and expected by the society and the existing methods of preventive work used by the state.
The scientific substantiation of approaches to researching female crime and the author’s own vision of the problem are used for working out recommendations aimed at enriching criminal law science in its search for optimal ways and effective means of counteracting female criminal behavior. Scientific substantiation of female criminal behavior allows the author to identify key trends for the development of social, criminal and penitentiary policy oriented at women. This problem has a considerable potential for further research touching upon not only criminal law, penitentiary and criminological spheres of work, but also political, ideological, economic, cultural-social, psychological and moral spheres of social life, which predetermined the contents of the current article.
A/Ci method using Dynamic Assimilation Technique v1
Authors: Tejera-Nieves Mauricio
Published: February 2024

The net CO2 assimilation (A) response to intercellular CO2concentration (Ci) is a fundamental measurement in photosynthesis and plant physiology research. Here, we optimized and compile a non-steady state Dynamic Assimilation Technique (DAT) protocol for A/Ci measurements. We tested this protocol in Tobacco (Nicotina tabacum), arabidopsis (Arabidopsis thaliana; Col-0), soybean (Glycine max ‘AG21XF1’, Asgrow, New Haven, CT, USA), potato (Solanum tuberosum; ‘PA01N32-1’), apple (Malus domestica ‘Jonagold Decoster PP#80’ on ‘EMLA 106’ rootstock) and the extremophile plant Rhyza Stricta, and compare the parameter estimations against conventional steady state A/Ci measurements. The DAT protocol reduced the measurement time by almost half without compromising estimations accuracy or precision. Estimations of biochemical limitations to photosynthesis were very consistent across all CO2 protocols, with slight differences in ribulose 1·5- bisphosphate carboxylase/oxygenase carboxylation limitation.

Published: February 2024

The ornamental plant sector is diversified and demanding in terms of quality, which includes plant nutrition. Thus, the objective of this work was to evaluate the leaf development of F. foetida var. Striata cultivated in a greenhouse under different nitrogen dosages and sources. A completely randomized experimental design was used, in a 3×3+1 factorial scheme, nitrogen doses were 100, 200 and 300 mg L-1 and sources with different nitrogen percentages: calcium nitrate, ammonium nitrate and urea, plus the additional treatment (control: no treatment), with six replications. The number of leaves, length, width and leaf area were evaluated. It was observed that there was full leaf development of plants grown in pots, at 390 days after transplanting, the plants had average parameters of 10.4 leaves/plant, 36.9 cm in leaf length and 6.3 cm leaf width. It was concluded that the different nitrogen doses and sources favored the quality of leaf development of F. foetida, preserving their ornamental characteristics in terms of shape and plasticity.

Authors: Marulanda-Zapata David Felipe , Barrera-Sánchez Carlos Felipe , Córdoba-Gaona Oscar de Jesús
Published: February 2024

The growth analysis is relevant to understanding and comparing in terms of physiological and productive behavior varieties. The study aims to determine the accumulation and distribution of dry matter through different phenological stages of development in four diploid potato varieties. For this, in a randomized complete block design with three replications, four varieties of diploid potato were evaluated: Paola, Violeta, Primavera, and Paysandú. Based on direct measurements of leaf area and dry matter of each organ, it was computed the growth indices of relative growth rate (RGR), net assimilation rate (NAR), leaf area relation (LAR), and source-sink relation. The duration of development stages of flowering, fruit, and tuber development was measured in terms of thermal time. Furthermore, the number of stems, stolons, and tubers was measured, and the yield was registered at the cycle end. The varieties Paola and Primavera reached a greater accumulation of dry matter in each organ and a greater number of tubers by plant about the varieties Paysandú and Violeta. The organs with the greater biomass accumulated were the leaves, stems, and tubers. The source and demand power had a considerable correlation between the NAR and RGR, which increased toward the end of the cycle for Paola and Primavera varieties. The yield and the beginning and duration of the growth stages were related to the season and the varieties.
In Vitro antifungal activity of ethanol extracts from Cnidoscolus urens L. in controlling Colletotrichum spp. in Lycopersicum esculentum: a sustainable agricultural perspective
Authors: Carrillo María Fernanda , Mora-Estupiñan Daniela Alejandra , Ortiz-Rojas Luz Yineth , Chaves-Bedoya Giovanni
Published: February 2024

Anthracnose, caused by the pathogenic fungi Colletotrichum spp., poses a significant threat to table tomato (Lycopersicum esculentum) cultivation. This study delves into the potential of plant extracts from Cnidoscolus urens L. as an alternative biocontrol strategy to combat this disease. Rich in secondary metabolites like terpenes, which are instrumental in plant defense, these extracts also comprise esters and fatty acids. Although the latter are not classified as secondary metabolites, they contribute significantly to the plant's biochemical makeup. Our objective was to gauge the in vitro inhibitory efficacy of ethanolic extracts derived from the leaves and stems of Cnidoscolus urens L. against Colletotrichum spp. To achieve this, an agar dilution method with varying extract concentrations was employed. The results showed that concentrations ranging from treatment 3 to treatment 8 effectively inhibited fungal mycelial growth. Interestingly, the extracts' origin, whether from leaves or stems, did not show any significant differential impact on their inhibitory activity. These insights emphasize the consistent effect of Cnidoscolus urens L. extracts in stalling Colletotrichum spp. growth, underscoring their potential as biological antifungal agents in agriculture. Given the pronounced in vitro effectiveness of both leaf and stem extracts, they beckon further exploration as part of sustainable agricultural strategies to combat prominent diseases like anthracnose.
Erotismo y castidad. Una guía iconográfica contra la lujuria en la sillería del coro de la catedral de Toledo.
Authors: Espí Forcén Carlos , Poveda Martínez Ana María
Published: February 2024

La sillería de la catedral de Toledo fue tallada a finales del siglo XV por un maestro del norte de Europa conocido como Rodrigo Alemán por un posible origen de Renania. Existía en estos momentos un rico comercio entre Flandes y los reinos de la península ibérica, que propició la llegada de numerosos artistas extranjeros al rico y emergente reino de Castilla. La sillería del coro de Toledo es especialmente conocida por los relieves que narran la reciente conquista de Granada; sin embargo, nuestro estudio se centrará en dilucidar el significado hermético oculto en los relieves complementarios de la marginalia tallada por el maestro Rodrigo Alemán en esta misma obra. En concreto, analizaremos las misericordias que incorporan conocidas imágenes de los Bestiarios medievales y la cultura popular con la intención de advertir al clero de los peligros de la tentación carnal. Si bien es cierto que Rodrigo Alemán fue un maestro extranjero, las imágenes que talló en el coro de la catedral toledana gozaban de una consolidada trayectoria en el arte medieval europeo, luego podemos asumir que el clero fue en gran parte consciente de su significado moral. El presente trabajo estudiará esta iconografía marginal como una guía visual contra el pecado de la lujuria con el fin de garantizar la salvación eterna a sus potenciales espectadores.

Extracranial Meningioma Metastasis: A Systematic Review of Clinical Characteristics, Management Strategies, and Outcomes
Authors: Khan Mohammad Faizan , Young Kurtis , Rauber Erin , Ogasawara Christian , Umana Giuseppe E. , Palmisciano Paolo , Watanabe Gina
Published: February 2024

Background: Meningioma is the most common type of intracranial neoplasm, accounting for approximately 40% of all primary brain tumors. Although these tumors are usually benign and slow-growing, extracranial metastasis can occur in less than 1% of cases. Due to the rarity, diagnosis can pose a challenge. In this systematic review, we summarize and analyze patient demographics, clinical characteristics, management strategies, and outcomes of patients with extracranial meningioma metastasis.
Project Methods: A systematic review was performed following the (PRISMA) guidelines. PubMed, Ovid EMBASE, Cochrane, Scopus, and Web of Science databases were searched. Clinical characteristics, management, and outcomes were analyzed.
Results: A total of 127 studies with 164 patients were included. There were 51% males and mean age of primary tumor diagnosis was 48 years (range, 8-91). Primary tumors were mostly located on the convexity of the brain (52%) and WHO grade 1 (38%) or grade 2 (37%). Histological findings were predominantly atypical (37%). Mean number of intracranial recurrences was 2 (range, 0-7) and occurred in 81% of cases. Average time between primary tumor and the first extracranial metastasis was 103 months (range, 2-450). The top three most common locations of metastases were the lungs (39%), spine (15%), and liver (12%). Most often, there was no change in grade (68%) from the primary tumor to the first metastasis. Gross total resection of the primary tumor was achieved in 76% of cases. Mean survival from primary diagnosis and survival from first metastasis was 118 and 31 months, respectively.
Conclusion/Impact: Mechanisms by which extracranial meningioma metastasis occur are still unclear, though do not appear to involve evolution into a more aggressive histologic type in most cases. In a patient with a history of intracranial meningioma recurrence and symptoms of lung, spine, or liver, dysfunction, extracranial meningioma metastasis should be considered within the differential.
A01: A Pilot Study of Student Cadres Mental Health at a Sport University During COVID-19
Authors: Yuan Yuan , Han Haijun , Guan Hongwei
Published: February 2024

Purpose: Over 90% of college students have experienced negative mental health symptoms due to the pandemic, according to a survey from BestColleges.com. More than half (54%) of college students believe COVID-19 circumstances have impacted their mental health. Although the pandemic's influence on mental health expanded, not all students have felt its effects to the same degree. Physical activity has been reported to have many physical and mental health benefits. Students at sport universities tend to participate in more sport and physical activity. During the pandemic, student cadres are expected to take more responsibilities such as coordinating COVID-19 tests and interacting with more students. The purpose of this study was to examine the mental health of student cadres at a sport university in southwest China. Methods: Literature research, field observation and a survey questionnaire were used in this study. Forty college student cadres were surveyed from a sport university in Sichuan province. The Self-rating Symptom Checklist-90 (SCL-90) scale was used to estimate the mental status of students. A total of 33 surveys were returned with 29 valid samples were analyzed. Among the samples there were 13 males and 16 females with an average age of 19.62. The results were compared with general college students’ mental health reported in the literature. Results: According to a recent systematic review by meta-analysis, the anxiety prevalence was 33% in Asia, 51% in Europe, and 56% in the USA. University students have a high prevalence of anxiety, indicating an increased mental health burden during this pandemic. Only 6.9% of student cadres in this study showed anxiety symptoms. According to the SLC-90 score, compared with the documented normal mental health rate (62.2%) in the literature, the survey found 79.31% of sport university student cadres are in a normal mental health status. Conclusion: COVID-19 pandemic has impacted college students’ mental health. However, the student cadres of the sport university had a higher rate of normal mental health than the average rate reported in the literature, even though they had more responsibility and risks of being exposed to positive cases. It indicates sport and physical activity may reduce the mental health impact caused by the pandemic.

Authors: Chen Jun , Wang Xiaozan , Chen Ouyi , Long Haizhu
Published: February 2024

Purpose: This study aimed to investigate the association of fundamental motor skills (FMS), perceived motor competence (PMC), physical activity (PA) in elementary school students, as well as to examine whether PMC mediated the relationship between FMS and PA. Methods: Participants were 470 3-6th grade students (210 boys vs. 242 girls; Mean age = 10.11 years old; SD = 1.19) at five elementary schools from the province of Hunan in China. The students’ FMS were assessed with The Test of Gross Motor Development-3, PMC was assessed using the perceived athletic competence sub-scale of Harter’s Self-perception profile for children and PA were assessed using Physical Activity Questionnaire for Older Children, respectively. Data were analyzed with descriptive statistics, independent sample t test, Pearson correlation coefficients, multiple regressions, and bootstrapping method. Results: The descriptive statistics showed that the students’ PA was generally in the moderate level (M =2.78, SD = 0.75). The boys’ total FMS mean score (M =72.63, SD = 9.62), ball skills mean score (M = 39.33, SD = 6.23), PMC mean score (M =2.78, SD= 0.66), PA mean score (M = 2.97, SD = 0.75) was higher than the girls respectively. The independent sample t test showed that significant difference in the mean score of total FMS, ball skills, PMC, PA between the boys and girls (t = 3.99, p < 0.001; t = 6.20, p < 0.001; t = 5.40, p < 0.001; t = 5.42, p < 0.001) respectively. Also, the bivariate correlations coefficients showed that FMS, PMC, and PA were related to each other at p < 0.01 level. The result of simple mediation analyses showed that PMC mediate the association between FMS and PA (Indirect effect = 0.07, 95%CI = [0.03, 0.11]). Conclusion: Good FMS levels are associated with a high level of PA. The relationship between FMS and PA was fully mediated by the PMC. This study suggests that improving FMS and maintaining appropriate levels of PMC may promote PA in elementary school students.

Purpose: At this stage, the increasingly fierce social competition makes college students face significant challenges while striving for development opportunities. They will encounter various setbacks and challenges, causing excessive psychological pressure on college students, which will affect their mental health. As an effective means to promote people's physical and mental development, physical exercise plays an important role in the development of college students, It plays a very important role in relieving college students' psychological pressure. Therefore, it is particularly important to study how physical exercise affects college students' psychological pressure and the role of other factors. The purpose of this study is to explore the impact of physical exercise on college students' psychological pressure, as well as the intermediary role between emotional intelligence, adversity beliefs, physical exercise, and college students' psychological pressure, it provides theoretical basis and empirical reference for relieving college students' psychological pressure. Methods: A convenient sampling method was used. 383 college students aged 18-25 were investigated by using WLEIS, Psychological Stress Scale, Physical Exercise Rating Scale (PARS-3) and Adversity Belief Scale. Results: (1) physical exercise, college students' psychological stress, emotional intelligence and belief in adversity were significantly correlated; (2) Physical exercise can negatively predict college students' psychological stress (direct effect=-0.0032, 95% CI:, Physical exercise does not have a separate intermediate role in the impact of physical exercise on college students' psychological stress through adversity beliefs (indirect effect=0.0001, 95% CI: [-0.0007, 0.0010]), but physical exercise has an impact on college students' psychological stress through the chain intermediary role of emotional intelligence and adversity beliefs (indirect effect=0.0008, 95% CI: [0.0003, 0.0014]). Conclusion: Physical exercise can have a direct impact on college students' psychological stress, and it can also have an impact on college students' psychological stress through the mediation of emotional intelligence and belief in adversity. In the face of numerous challenges in the society, college students can relieve the psychological pressure brought about by life and study through physical exercise and promote their own mental health by cultivating their own belief in adversity and emotional intelligence, so as to meet the challenges in the future with a more positive outlook.

Authors: Ye Sunyue
Published: February 2024

Purpose: To understand the longitudinal association of screen time (ST) and its changes on body mass index (BMI) and obesity in Chinese preschool children. Methods: Parents of 735 preschoolers participated in our studies at baseline and were followed up one year interval, in Jiaxing, China. Linear regression models and generalized linear models were used to analyze the prospective association of ST and its changes with BMI and obesity in preschool-aged children. Relative risks (RR) and 95% confidence intervals (CI) were used to describe the effect level of each factor upon BMI and obesity at follow-up. Results: A total of 624 preschoolers, including 319 boys (51.1%) and 305 girls (48.9%) were followed up. The increase of ST (from ≤1h/d at baseline to >1h/d at follow-up, β (SE)=0.45 (0.15), p=0.003) and preschoolers’ age at baseline (β (SE)=-0.21 (0.10), p=0.039) were prospectively associated with BMI in preschoolers at follow-up, and preschoolers’ ST from ≤1 h/day to >1 h/day (RR: 2.49, 95% CI: 1.20-5.08, p=0.014) were related to obesity in preschoolers at follow-up after adjusting of sex, age, primary caregiver, and one child. Conclusions: The unfavorable changes of ST were associated with BMI and obesity in preschool-aged children. Future intervention studies were needed to confirm our results.

Purpose: Mandated social distancing to prevent the spread of COVID-19 pandemic has brought more anxiety and stress to college students. The primary purpose of this study was to examine whether college students' participation in sports club activities can reduce anxiety and stress. The secondary purpose was to compare the effects of different types of sport clubs. Methods: The sample consisted of 242 college students (143 males; mean age=22.63 years old) in an academically prestigious university. They were voluntarily enrolled in either team sports clubs, such as volleyball, football, baseball, and softball, etc. (n=96), or individual sports clubs, such as squash, cycling, mountaineering, etc. (n=146). They responded to validated scales to assess perceived stress (Sheldon Cohen, 1983) and well-being (Diener & Biswas-Diener, 2009). Self-compiled questionnaires on motivation to join sports clubs and basic information on club organization activities were collected. All surveys were conducted in October 2021. Results: A considerable proportion of students (34.7%) participated in sports clubs to reduce academic pressure. Most of them (72.26%) have already recognized the physical and mental health benefits of physical activity. Significant decreases were observed for perceived stress in both groups: team sports group (ΔM = -0.76, p < 0.01), and individual sports group (ΔM= -0.77, p < 0.01). A significant increase in well-being was observed in two types of courses led by the team sports group (ΔM=1.55, p < 0.01) followed by the individual sports group (ΔM=1.34, p < 0.01). Individual sports clubs have a more pronounced effect on reducing negative emotions than team sports clubs (ΔM = -2.01, p < 0.05). Conclusion: Participation in both team sports clubs and individual sports clubs reduced perceived stress and increased well-being. Individual sports clubs had more decreases in negative emotions compared to team sports clubs.
A111: Relationship Between Physical Activity and Mental Toughness
Authors: Wang Ke , Hu Jiaju
Published: February 2024

Purpose: Physical activity has favorable impacts on exercisers' stress levels, psychological
distress and anxiety, emotional regulation, and mental wellness. In recent years, the global outbreak of COVID-19
has subtly altered college students' lifestyles. Studies have shown that the physical and mental health of students
has deteriorated dramatically, which is alarming. Mental toughness refers to the ability to adapt well in the face
of major pressures, setbacks, and adversity in life. The purpose of the present study was to examine variations in
mental toughness depending on the intensity, length, and frequency of physical activity. Methods: A
total of 3,120 Chinese college students participated in this study. In the spring semester of 2022, participants
were given the demographic questionnaire, the Physical Activity Rating Scale (PARS-3), and the Chinese version of
the Mental Resilience Scale (CD-RISC). 3049 students completed the survey. Independent sample t test, one-way analysis
of variance (ANOVA), correlation analysis, and regression analysis were performed using SPSS 25.0 statistical
software. Results: The physical activity level differed significantly across sex (t =
14.37, p < 0.001), grade (F=3.72, p < 0.05), and monthly living
expenses (F = 5.70, p < 0.001). The mental toughness had significant differences across
sex (t = 4.55, p < 0.001), grade (F = 3.35, p < 0.05), and monthly living
expenses (F = 5.41, p < 0.001). There were significant differences in mental toughness
across different levels of physical activity intensity (F = 39.28, p < 0.001), different length of
physical activity (F = 33.35, p < 0.001), different frequency of physical
activity (F = 30.14, p < 0.001), and different levels of physical
activity (F = 91.55, p < 0.001). Physical activity was significantly and positively
correlated with mental toughness (r = 0.26, p < 0.01). Conclusion: Male students
exhibited significantly higher levels of physical activity than their female counterparts, and freshmen demonstrated
greater physical activity than students in other grades. Additionally, the amount of physical activity among college
students was influenced by their monthly living expenses. The mental toughness score of male students was notably
higher than that of female students, with freshmen scoring significantly higher than students in other grades. In
comparison to other levels of physical activity, engaging in a high quantity of exercise, high-intensity short-duration
exercise, more than 60 minutes of activity time, and a daily activity frequency had the most pronounced impact on enhancing
mental toughness. Moreover, there was a positive correlation between physical activity and mental toughness.
