A Study on the Influence of the 8th Century A.D. Image of Feitian in the Mogao Caves on the Character Design of Modern Chinese Films
Authors: Jin Jiasheng , Sharudin Sharul Azim Bin
Published: January 2024

The Dunhuang cave community represented by the Mogao Grottoes is the most dazzling historical legacy of the development of the Silk Road civilization, and the murals in the Dunhuang caves are the “witnesses” of the development of human civilization, the crystallization of the convergence and integration of ancient Chinese civilization and world civilization, and the valuable heritage of the Chinese nation. The art of Dunhuang murals has further developed and changed through different epochs and cultural fusions, and the contemporary interpretation and innovation of its aesthetic concepts, artistic styles, and cultural values have become particularly important and valuable. In the context of artistic creation in the eighth century A.D., this study examines in-depth the stylistic characteristics of the Flying Sky image in the Mogao Grottoes; using methods such as observation, investigation, analysis, etc., and through the study and research on the styling of modern animation characters, it is found that the copying of the ancient art can not realize its maximum value, and that the traditional art can be inherited in a revolutionary way by disseminating it through the medium of modern media.
Progress in the Study of Significant Mutated Genes and Molecular Biological Factors in Cervical Tumors
Authors: Liang Jiajing , Wei Xiuling , Zhao Shibo
Published: January 2024

Cervical cancer is the most prevalent gynecologic malignancy in developing countries, with incidence and mortality rates continuing to rise. Despite widespread research on cervical cancer, the specific mechanisms and synergistic factors underlying its occurrence remain unclear. In recent years, there has been a growing interest in the relationship between gene mutations and cervical cancer. Numerous studies have demonstrated that alterations in oncogenes, tumor suppressor genes, and related regulatory genes are closely associated with the development and progression of cervical cancer. The application of genome sequencing technology in malignant tumors has allowed for the identification of additional gene mutations in cervical cancer. By identifying significantly mutated genes, we can further target malignancy driver genes, which may be the key to uncovering the intrinsic mechanisms of sexual tumors. Therefore, a review of the current status of research on mutated genes in cervical cancer and factors associated with recurrence after treatment of early-stage cervical cancer can provide new insights for mechanistic studies, diagnosis, and targeted therapy of cervical cancer.

Authors: Hong Xueting , Chen Xichen
Published: January 2024

Lung cancer is the malignant tumor with the highest incidence and mortality in our country and even in the world. The radical rate of conventional therapy, such as simple radiotherapy, chemotherapy, operation, traditional Chinese medicine treatment is low and the effect is not ideal. Bronchial lung cancer is one of the most common causes of massive hemoptysis. Vascular interventional therapy has become the first choice in clinical treatment of acute massive hemoptysis. Interventional therapy for lung cancer patients, as a safe, efficient, minimally invasive and economical treatment, has been widely used at home and abroad. However, due to inadequate patient assessment, equipment may not be advanced enough, and treatment techniques need to be developed, more or less postoperative complications associated with interventional therapy may occur. This article reviews the research status of interventional therapy and complication prevention in patients with lung cancer hemoptysis as follows.
Digital Lifeworld and Communicative Interaction: Conceptualizing the Transformative Potentials of Social Networking in the Public Sphere
Authors: Zhang Minglei
Published: January 2024

To understand how digital social media influences the reconceptualization of the Habermasian notion of the public sphere, I use “digital lifeworld” to describe people’s networking through digital affordances in the public sphere. Regarding how communicative interactions in the digital lifeworld contribute to the transformational potentials in the public sphere, I investigate three paradigms in conceptualizing the communicative interaction: connectivity (how to network), collectivity (what networking entails), and cooperativity (how to sustain networks and networking). Networking is the core to the conceptualization of this framework because networking constitutes the key component in the formation of the lifeworld and accounts for the interactive potentials in challenging the dominant interest in the public sphere. Thus, the influence of networking in the lifeworld where public opinions collide makes the public sphere a transformative structure, and this theoretical framework can help locate the emergent networks that encompass stronger tendencies to influence the public sphere.

Senator Ayogu Eze v. Hon. Ifeanyi Lawrence Ugwuanyi and Ors: An Answer to Locus Standi and Jurisdiction in Nigerian Jurisprudence
Authors: Ngwu Godwin Emeka
Published: January 2024

Equally settled is the fact that as at the moment, the only window opened for the courts to entertain action on and/or concerning nomination of candidates for any election by political parties is as provided under section 87(8) or (9) or (10) of the Electoral, Act 2010, (as amended)... “As a result of the above provision conferring (sic) this court has held, in very many cases, that only an aspirant in the primary election conducted by the political party can question the result or nomination or declaration of any person by the party as the winner of the primary election. Consequently, the sponsored candidate of the political party concerned in the election in issue. It follows, therefore, that no other person or member of the political party concerned, has the locus to challenge or question the nomination of any candidate by a political party for any election.” Even at the risk of repetition, the appellant was not a candidate in the governorship primary election that was held in Enugu State in 2015, as such he lacked the locus to challenge the declaration of the 4th respondent as the winner of the said primary. However, section 87(9) of the Electoral Act, 2010 (as amended) gives the courts very limited jurisdiction to ensure that in the selection or nomination process, political parties do not act arbitrarily but within the confines of their constitution and Electoral Guidelines, and in accordance with the provisions of the Electoral Act. The appellant failed to bring himself within the purview of section 87 (9) of the Electoral Act He was not an aspirant in the primary election from which the 4th respondent emerged. He therefore lacked the locus standi to institute the action. There is no reason to interfere with the sound reasoning of the court. Jurisdiction is the bedrock of every litigation be it civil of criminal, however, in this case, the court is heavily clothed with jurisdiction to entertain a matter bordering on political parties primary elections by virtue of section 87(8) or (9) or (10) of the Electoral Act 2010, as amended..., Locus-Standi is an indisputable principle of law that can be raised at any stage of judicial proceedings, locus-Standi determines whether a party to a litigation is armed with power or legal capacity to institute an action before the courts of law, however Senator Ayogu Eze who is the plaintiff/ respondent lacked the right of action, on his failure to participate in primary elections organized by the national committee headed by king Asara; has forfeited or negatived his legal capacity to institute action in the court of first instance.

In the folk tradition, there are a lot of folk art to stage opera characters for the performance of the theme, while opera art has become more and more popular. In the form of painting to describe the opera, in the Ming and Qing Dynasties, some artists began to use this way to express the opera, but the number is very small and did not form a large scale, and it did not break away from the style of literati painting, resulting in the failure to cause more researchers at the time of the pro-gaze. After the modern society, a group of overseas artists returned, the advanced western humanistic thought into the painting, bold attempt to a variety of painting language performance, the theme of the performance is also more extensive. Mr. Guan Liang’s opera figure painting is a model of this period. He is an explorer who takes opera figures as the main performance theme of painting, and combines his own creative experience to successfully create countless opera figures with different personalities in the performance language of Chinese painting. Finally, he formed his own independent painting style, different from the artistic style of literati painting. After that, more and more painters began to express operas in Chinese paintings. Among them, Han Yu, Gao Made, Lin Fengmian and so on, the works have their own unique spiritual outlook, explored a new path of painting, these excellent works not only from the inheritance of traditional culture, but also reflects the rich and colorful art of today’s era, in the history of Chinese art will leave a glorious page.

The Paradox of Globalization: Unraveling the Short and Long-Term Impacts on Income Inequality in Indonesia
Authors: Putri Mega Amelia , Karimi Syafruddin
Published: January 2024

This study investigates the impact of globalization and financial growth on income inequality in Indonesia using empirical data from 1995 to 2020. The analysis reveals that globalization and financial development, while initially appearing advantageous, can exacerbate income inequality over time. In Model I, the overall measure of globalization contributes to income inequality in both the short and long run. Initially, globalization may reduce income inequality, but its long-term effects are detrimental. Financial development and inflation in Indonesia also have a significant and positive impact on income inequality in this model. Model II shows that economic, political, and social globalization have statistically significant impacts on income inequality in both the short and long term. Economic and political globalization can help mitigate income inequality over time, but in the short term, income inequality in Indonesia worsens. Social globalization, on the other hand, consistently has a positive influence on income disparity in both the short and long term. The study highlights the need for proactive government measures to maintain the stability of economic, political, and social globalization. Policymakers should implement progressive policies that address the adverse effects of globalization on income distribution to ensure a more equitable society.

The independent variables used in this study are as follows: firm value (X1) measured using PBV and financial performance (X2) measured using ROA, and the dependent variable used is stock price. The sample used in this study consisted of 45 companies in the LQ45 list in the 2022 period which were determined based on purposive sampling. In this study, the data analysis used used multiple linear regression analysis (t test and F test) processed with SPSS. Judging from the multiple linear regression model, the results of the t test (partial) state that the value of the company (PBV) has a negative and insignificant effect on stock prices, and financial performance (ROA) has a positive and significant effect on stock prices. From the day of the F test, it shows that company value (PBV) and financial performance (ROA) together have a positive and significant effect on stock prices.

Published: January 2024

Diabetes is a disease that contributes to a relatively high mortality rate. The human death rate due to diabetes is a widespread issue globally. The primary goal of this research is to predict individuals suffering from diabetes using a publicly available dataset from the UCI Repository with the Diabetes Disease dataset. To obtain the best classification algorithm, a comparison is made among three algorithms: KNN, Naive Bayes, and Random Forest, commonly used for predicting diabetes. The comparison results indicate that the Random Forest algorithm is the appropriate and accurate algorithm for predicting individuals with diabetes, with an accuracy rate of 97%.
Overview and Exploratory Analyses of CICIDS2017 Intrusion Detection Dataset
Authors: OYELAKIN Akinyemi Moruff
Published: January 2024

Intrusion detection systems are used to detect attacks in a network.  Machine learning (ML) approaches have been widely used to build such Intrusion Detection Systems (IDSs) because they are more accurate when built from a very large and representative dataset. In recent times, one of the benchmark datasets that are used to build ML-based Intrusion Detection models is CICIDS2017 dataset. The dataset is contained in eight groups and was collected from the Canadian Institute on Cyber Security dataset repository.  The dataset is available in both PCAP and netflow formats. This study used the netflow records in the CIDIDS2017 dataset as they are found to contain newer attacks,very large and are found useful for traffic analysis. Exploratory Data Analysis (EDA) techniques were used to reveal various characteristics of the dataset. The general objective is to provide more insights on the nature, structure and issues with the dataset so as  to identify the best ways for using it to achieve improved ML-based IDS models. Furthermore, some of the open problems that can arise from the use of the dataset in any machine learning-based Intrusion Detection systems are highlighted and possible solutions are briefly discussed. The EDA techniques used revealed important relationships among input variables and the target class. The study concluded that the EDA can better influence the decision of future IDS researches that use the dataset. Thus, improved machine learning-based intrusion detection systems can be built from the dataset once it is well understood and pre-processed.
Full-Body Circuit Training Improves Body Composition and Cardiorespiratory Fitness in Overweight Sedentary Adults

Published: January 2024

Obesity and low cardiorespiratory fitness are major risk factors for numerous non-communicable diseases and mortality, and efficient treatment protocols to counteract these conditions are highly warranted. We evaluated the effect of high-intensity circuit training (CIT) on body composition and cardiorespiratory fitness of sedentary overweight individuals. Cardiorespiratory and body composition were assessed before and after a 8-week circuit training (CIT; four sessions of full-body CIT per week; age, 38 ± 9 years old; height, 174 ± 10 cm; body mass, 93.1 ± 22.2 kg; n = 32), and 8-week inactiv-ity (CON; neither training nor lifestyle changes from week; 0–8 age, 39 ± 7 years old, height, 168 ± 8 cm, body mass, 89.5 ± 17.5 kg; n = 33). The two-way repeated-measures ANOVA revealed moderate to large reductions were observed in body mass, BMI, and fat percentage after CIT (d=0.43–0.81; P<0.05). In contrast, all body composition parameters remained stable after 8-week inactivity (P<0.05). A small to moderate group x moment interaction was found for body mass, BMI and % fat (d=0.10–0.60; P<0.05). Small improvements in VO2max were observed after CIT (d=0.48 [0.11–0.85]; P=0.010), while small to moderate reductions were observed in VO2max and PV were observed after inactivity (d=0.47 [0.11–0.83] and 0.64 [0.26–1.01], respectively; P<0.05). A small moment x group interaction was observed for VO2max (d= 0.19 [0.13–0.26]; P<0.001). Our findings suggest that 8-week of full-body circuit training may improve cardiorespiratory fitness and body composition in sedentary overweight individuals.

Authors: Maciel Marcos Goncalves , Uvinha Ricardo Ricci
Published: January 2024

Physical activity is recognized as an important means for promoting health and quality of life. However, the discussion regarding this practice as a human right needs to be expanded. The objective of this study was to analyze the perceptions of professionals from two scientific institutions in Brazil regarding leisure-time physical activity as a social right. The research was descriptive, documentary, cross-sectional, and exploratory in nature, with non-probabilistic sampling. A semi-structured questionnaire was adopted in Google Forms format, and content analysis was used for data analysis. The sample consisted of 80 participants. The main results highlight the recognition of leisure time and health as social rights, as well as the existence of barriers such as social inequalities in the realization of these rights. However, there is evidence of progress in public policies in Brazil that aim to democratize leisure-time physical activity as a social right.

The aim of this study was to investigate the correlation of anthropometric variables and motor abilities in change of direction speed and reactive agility performance in young tennis players. 50 tennis players (age 12.3 ± 1.2 years, height 156.7 ± 12.8 cm, body mass 45.9 ± 8.9 kg), who were ranked within the top 50 ranking places of the National Tennis Association, as well as within the top 300 on the international "Tennis Europe" rankings, participated in the study. The sample of anthropometric variables in this study comprised the measurement of participant height, body mass, body mass index and percentage of body fat. Also, participants performed tests assessing speed (5, 10, and 20 m sprints), agility (20 yards, 4x10 yards, T–test, TENCODS, and TENRAG), and explosive power (countermovement jump, single-leg countermovement jump, squat jump, standing long jump and single-leg triple jump). The results showed that there is a statistically significant correlation of agility with anthropometric characteristics, running speed tests and horizontal explosive power variables, whereas there was no significant correlation with vertical explosive power variables. In conclusion, the results of this research confirmed the hypothesis that there is a significant correlation in almost all anthropometric variables and motor abilities in change of direction speed and reactive agility performance in young tennis players. Thus, our findings provide useful information for coaches to create a wide range of tennis-specific exercises to develop performance, especially in a players neuromuscular fitness.

Authors: Zemková Erika
Published: January 2024

Given the importance of core stability and strength in athletic performance and in the activities of daily living, its assessment should be considered an integral part of functional diagnostics. This paper presents our approach to assessing the power performance during exercises involving muscles of the core, such as lifting tasks and trunk rotations under a variety of conditions and in various population. Experience showed that core stability and strength tests are able to reveal within and between-group differences in core performance and the effectiveness of training or rehabilitation programs in competitive athletes, as well as in general population of different age and physical fitness.
