The academic paper examines the impact of digital innovations on the parameters of the operational, financial, economic and managerial activities of enterprises. Indicators of the formation and development of digital management practice are studied; various criteria are considered, which can be used to determine the presence of digital phenomena in the strategy and their impact on the development of the organization’s management system. In light of the developments in the theory and practice of managing social-economic systems, the academic paper outlines the unique features of the management system of contemporary businesses that should be considered. It is emphasized that the era of the digital economy creates prerequisites for improving the efficiency of enterprises. Digital innovations generate new means of social interaction between employees; they transform economic relations between the enterprise and its business partners. More rational and cost-effective methods of cooperation and coordination are emerging to jointly solve particular business problems. However, at the same time, digital innovations also generate negative effects that are informational in nature. The number of models of unfair competition based on the dissemination of deliberately planned disinformation among market participants is growing; the number of economic crimes in cyberspace is increasing dramatically. That is precisely why modern innovative technologies such as blockchain and artificial intelligence provide for open, secure collaboration within the digital information space, and the application of analytics to the data obtained allows for increasing the competitiveness of the business. The rapid development of technology and the emergence of artificial intelligence (AI) have had a significant impact on the formation of digital innovations. The introduction of AI can significantly increase the effectiveness of any company’s HR strategies and facilitate the work of its managers by helping to collect and analyze large amounts of data.

Published: July 2024

There are still many important obstacles that make evaluating COVID-19 as a pandemic difficult. Utilising all of the tools and resources available in the field is essential to overcoming these obstacles. The popular reverse transcription polymerase chain reaction (RT-PCR) technique is useful for detecting viral presence, but it is not very good at determining the severity of a disease. In this work, we present a simplified and reliable automated method that uses CT scan images to classify COVID-19 severity into three stages: mild, moderate, and severe. Three types of characteristics are extracted for this classification: infection ratio, statistical texture features (mean, standard deviation, skewness, and kurtosis), and GLCM/GLRLM texture features. The classification is based on a straightforward segmentation approach. For scan classification, four machine learning methods are used: decision trees, support vector machines, K-nearest neighbours, and Naïve Bayes. Four essential phases are included in our suggested model: preprocessing, feature extraction, classification, and performance assessment. using Support Vector Machines (SVM) yields impressive segmentation accuracy of 99.12% for normal, 98.24% for mild, 98.73% for moderate, and 99.9% for severe COVID-19 infection. The model outperforms previous models with an amazing area under the curve (AUC) of 0.99. This development is expected to improve diagnostic accuracy, facilitate faster evaluation of infection stage, and guarantee prompt, customised therapy delivery by medical practitioners.

All tissues contain zinc, the most prevalent intracellular trace element. Muscle and bone contain the highest amounts of zinc. A subchronic toxicity study was carried out to determine the effects of overdose from zinc sulphate induced biochemical and histopathological changes in the rats' liver, stomach, pancreas, kidney, brain, and spleen. Forty male albino rats were used in this study. Twenty, forty, and sixty mg/kg of zinc sulphate were given to the second group during the six-week study period, while the first group served as the control. Samples of the liver, kidney, and serum were collected for examination. The histological changes seen during the study were restricted to the rats at the dose rate of 60 mg/kg body weight, with the exception of vacuolation in the brains and hemosiderosis in the spleens of rats exposed to zinc alone. Degenerated mucosal epithelial cells involving the glands and muscular mucosa were observed under a microscope in the stomachs of the rats. Hepatic cell degeneration was observed, especially in the liver portal regions of the rats. Tubular necrosis, glomerular degeneration, and mononuclear cell infiltration into the tubule interstices were found during the histopathological examination of the kidneys. One of the most noticeable changes in the brains that was seen was neuronal degeneration. Rat spleens with both the white and red pulps showed degenerated pancreatic acinar cells and depopulated splenic cells. In comparison to the control group, there has been a significant (p≤0.01) increase in the serum levels of biochemistry tests. The histological findings show multi focal nephritis and leucocyte infiltration in the kidney, along with perivascular leucocyte infiltration and hepatic degeneration. Rats' histopathological changes in the stomach, liver, kidney, brain, pancreas, and spleen were found to be improved when zinc supplements were given to them; the histoarchitecture of the rats' organs was only slightly altered.

Authors: Do Thien Tat , Pham Tham Thi Huong
Published: July 2024

This study explores the relationship between peer pressure and friendship quality among middle school students in Vietnam, aiming to understand how these factors interact and affect students' social experiences and academic outcomes. A convenience sampling approach was used to survey 403 students from Tan Tao A Secondary School and Viet My Secondary School during the 2023-2024 academic year. Participants completed the Perceived Peer Pressure Scale and the Friendship Quality Scale. Data were analyzed using SPSS to conduct descriptive and comparative statistical analyses. The findings indicate a significant relationship between peer pressure and friendship quality. Students with high-quality friendships reported higher levels of resistance to peer pressure and positive peer encouragement, while those with weaker friendships were more vulnerable to negative influences. Notably, students experiencing higher levels of peer pressure also reported higher friendship quality scores, suggesting a complex interplay between these factors. Strong, supportive friendships can act as a buffer against negative peer pressure, promoting resilience and positive behaviors among middle school students. Educational interventions that foster positive peer relationships and provide support for students with weaker friendships are essential. Further research should explore the longitudinal impact of these relationships to inform more effective interventions.

Published: July 2024

The majority of Indonesia's population adheres to Islam at 87.2%. The large number of adherents of Islam affects the number of requests for halal products, especially broiler meat in the Special Region of Yogyakarta. This is supported by the large number of Chicken Slaughter Houses (CSH) with a total of 1,232 in the Special Region of Yogyakarta. However, only 49 slaughterhouses have been certified halal by Majelis Ulama Indonesia (MUI). This is not proportional to the amount of CSH. The purpose of this study is to investigate the factors that influence the intention of CSH owners to make halal certificates using the Theory of Planned Behavior (TPB) model with the addition of religiosity and knowledge factors using purposive sampling method. The questionnaire was distributed face to face that targeted a minimum of 100 respondents with the specific criteria of CSH with age minimum 2 years old. The collected data was examined using the SPSS application, which is a multiple linear regression module. This study uses the variables religiosity, knowledge, perception control, subjective norms, attitudes, and intentions. The conceptual model consists of 2 models. The first model is the influence of religiosity factors, and knowledge of the attitude of CSH owners in making halal certification. The second model is attitudes, subjective norms, and perception control of CSH owners in making halal certification. The results showed that the knowledge and religiosity factors had a significant positive effect on the attitude of CSH owners in making halal certification. Attitude factors, perception control, and subjective norms have a significant effect on the intention of CSH owners in making halal certification. These factors can simultaneously explain the attitude of CSH owners in making halal certification by 2.9%, and the intention of CSH owners in making halal certification is 7.5% while the rest is influenced by other factors.

Authors: Parreño Samuel John , Anter Maria Cristine Joy
Published: July 2024

This study leverages Topological Data Analysis and Persistent Homology to explore the Philippine inflation data from 1958 to 2023, aiming to uncover complex structures that traditional analysis might miss. By exceeding conventional econometric methods, we sought to reveal intricate cycles and trends within the economic landscape. Our approach revealed a mix of short-lived and persistent topological features within the inflation data, suggesting the presence of underlying economic cycles and seasonal effects with notable implications on inflation trends. Utilizing TDA allowed us to identify and quantify these features through Betti numbers, persistence diagrams, barcodes, landscapes, and silhouettes, providing a comprehensive visual and quantitative framework for understanding the topological structure of the data. The findings underscore the potential of TDA to profoundly enrich economic indicator analysis by uncovering the temporal dynamics and hidden structures within inflation rates. This methodology not only advances economic research techniques but also supports the development of more nuanced economic policies and forecasting strategies. The study confirms that TDA can offer a novel perspective in economic data analysis, highlighting both stability and change within the inflationary process and suggesting the existence of recurring economic phenomena. Such insights could pave the way for further research integrating TDA with traditional economic models, potentially leading to a deeper understanding and more accurate predictions of economic trends.

Технологічні передумови та методи вилучення германію на прикладі буровугільних родовищ Закарпаття
Authors: Burlutskyy M. S.
Published: July 2024

У зв’язку з бурхливим розвитком технологій попит на германій різко підвищився та почалися інтенсивні пошуки джерел його отримання. Виявилось, що головним сировинним джерелом германію може бути викопне вугілля. За прогнозами, до 2030 р. попит на германій становитиме 320–400 т на рік, а його виробництво збiльшиться майже в 1,5 раза. Найбільше зростання очікується в інфрачервоній та волоконній оптиці (5,6 % на рік).Українські вугільні родовища, що характеризуються германієвою металоносністю, на сьогодні не використовуються в повному обсязі за комплексним призначенням. Обсяги споживання у вітчизняному мінерально-сировинному комплексі германію оцінюються на рівні 2–4 т щороку, при цьому Україна в минулі періоди була здатна експортувати в декілька разів більше металу у розвинуті країни Європи й Азії.Метою роботи є вивчення геохімічних особливостей бурого вугілля Закарпаття, аналіз існуючих методів вилучення германію в світі та застосування технологічно можливих та економічно доцільних методів вилучення германію з бурого вугілля цього регіону.В роботі проведено аналіз попередніх досліджень щодо методів вилучення германію з кам’яного та бурого вугілля, зокрема у Закарпатті. Використано матеріали вітчизняних та закордонних авторів, що вивчали це питання в різні роки, в тому числі стосовно родовищ кам’яного та бурого вугілля.
Особливості пошуків родовищ алмазів мінералогічними методами в різних ландшафтно-геологічних умовах

Published: July 2024

Дана стаття має методичну направленість, в якій обговорюються особливості використання шліхо-мінералогічних методів при пошуках корінних і розсипних родовищ алмазів. Розглянуті ключові моменти теорії формування осадових колекторів, які вміщують ореоли розсіювання мінералів-супутників та розсипи алмазів. Показано, що у зв’язку з циклічністю седиментогенезу в алмазоносних регіонах під час формування ореолів відбувається перевідкладення, часто неодноразове, асоціацій кімберлітових мінералів, унаслідок чого в первинному заляганні вони трапляються не так часто. Чергування циклів седиментогенезу і повторне відкладення мінералів із більш ранніх колекторів у знову сформовані відклади призводить до того, що в ореолах і розсипах накопичується матеріал різних епох розмиву кімберлітів. Співвідношення й абсолютні вмісти різних генерацій мінералів в ореолах можуть бути абсолютно різними. Цими параметрами визначається ступінь контрастності конкретного ореолу, а отже, рівень ефективності пошуків.Розглянуті пошукові ситуації в різних алмазоносних провінціях – Анголі, Бразилії, Саха-Якутії, Україні, а також обговорюються особливості шліхо-мінералогічних пошуків у цих регіонах. Наведені загальні принципи використання мінералогічних методів у різних ландшафтно-геологічних умовах територій.Надано рекомендації щодо проведення комплексу робіт для підготовки мінералого-палеогеологічної основи до прогнозної карти. Зазначено, що для цього необхідно виконати комплекс досліджень, який містить вивчення типоморфізму індикаторних мінералів, літолого-фаціальних і речовинних особливостей теригенних відкладів, що їх вміщують, а також провести палеогеологічні і палеогеографічні реконструкції.

BACKGROUND: Caregivers in Japan experience a high prevalence of low back pain (LBP), with age, sex, individual pain experiences, and central sensitization symptoms potentially influencing its chronic progression. OBJECTIVE: To determine the prevalence of LBP among caregivers, as well as its relation to age and sex, and explore work status, psychological factors, and central sensitization symptoms as contributing factors to chronic LBP (CLBP). METHODS: A large-scale cross-sectional survey was conducted among 1214 caregivers in 35 geriatric healthcare facilities. The survey assessed LBP and CLBP prevalence, work status, psychological factors, and central sensitization-related symptoms. Multivariate logistic regression analysis was used to identify factors influencing CLBP. RESULTS: Among 936 valid respondents, the LBP prevalence was 69.2%. No significant sex differences were found in the prevalence of LBP and CLBP. Old age, higher pain severity, and severe symptoms related to central sensitization increased the risk of CLBP. However, work status and psychological factors did not significantly contribute to CLBP. CONCLUSION: There is a high prevalence of LBP among caregivers, age and individual pain experience significantly impact CLBP. These findings emphasize the need for therapeutic strategies to manage pain intensity, especially in the acute phase, to prevent the progression to chronicity.

Authors: Shi Chencui , Zou Qiangdong , Wei Hong
Published: July 2024

BACKGROUND: During pregnancy, structural and functional changes usually occur in the body, which has various consequences, including lower back pain (LBP) and hypothyroidism. One of the risk factors for these problems is physical inactivity. OBJECTIVE: This study aimed to investigate the association of back pain and physical inactivity, weight gain, and hypothyroidism in pregnant women. METHODS: In this cohort study, 420 pregnant women (26.333 ± 5.820 years old) were included. At first, participants answered this question: “Do you have any plans for pregnancy in the next month?” If the answer was yes, further evaluations were performed. The physical activity and pain intensity were measured by the International Physical Activity Questionnaire Short Form (IPAQ-S) and Visual Analogue Scale. Serum TSH was measured by automated chemiluminescence and commercial kits. Measurements were conducted before, the first, second, and third trimester of pregnancy. RESULTS: Women reporting LBP were less engaged in physical activities and weight gained in the second and third trimesters of pregnancy was significantly higher than pregnant women without LBP (p< 0.05). TSH level and weight gained in pregnant women with low physical activity level was significantly higher than pregnant women with moderate and high physical activity (p< 0.05) (without significant difference in TSH and BMI). The physical inactivity (before: OR: 1.11 95% CI: 0.89 to 1.22; first trimester: OR: 1.09 95% CI: 1.02 to 1.59; second trimester: OR: 0.92 95% CI: 0.87 to 1.31; third trimester: OR: 1.12 95% CI: 1.02 to 1.39), TSH (OR: 0.85 95% CI: 0.57 to 1.29), and weight gain (second trimester: OR: 0.87 95% CI: 0.92 to 1.59; third trimester: OR: 1.44 95% CI: 1.02 to 1.98; p< 0.05) did predict increased pain intensity. CONCLUSION: Using health-oriented approaches to increase physical activity and normalize thyroid function and weight gain during pregnancy can have beneficial effects on LBP.
Research on Korean literature corpus processing based on computer system improved TF-IDF algorithm
Authors: Xue Jing
Published: July 2024

Art is a symbol of people’s thoughts, and among many forms of artistic expression, literature is the most direct one, which can present art directly to people. How to correctly understand language materials in literature is crucial for understanding literary works and realizing their artistic value. Therefore, in order to strengthen the understanding of Korean literature and analyze its core ideas, this article utilizes modern computer technology and improved Term Frequency-Inverse Document Frequency (TF-IDF) algorithm to process the corpus of Korean literature, in order to quickly extract valuable textual information from Korean literature and facilitate reading and understanding. At the same time, a Korean literature corpus processing model was constructed based on deep learning algorithms. This model is based on the Natural Language Processing (NLP) algorithm, selecting Word Frequency Inverse Document Frequency (TF-IDF) as the feature to calculate the feature weight of keywords. By weighting the naive Bayesian algorithm, it achieves the classification and processing of expected text data in Korean literature. The results of multiple experiments show that the classification accuracy of the model exceeds 97.7%, and the classification recall rate is as high as 94.2%, indicating that the model can effectively achieve corpus processing in Korean literature.

BACKGROUND: Despite improvements, survival rates for gastric cancer remain low, even in developed countries, confirming the role of primary and secondary prevention. OBJECTIVE: This study aims to demonstrate the role of additional suspension sutures on the esophagojejunal anastomosis (EJA) to strengthen the anastomosis, i.e., relieve the mechanical suture. METHODS: A retrospective cohort study was conducted from 2011 to 2022 at the Clinic for Surgery, University Clinical Center Tuzla, Bosnia and Herzegovina. The experimental group consisted of patients placed with a suspension suture at the esophagojejunal anastomosis (EJA) site after total gastrectomy. The control group was patients without a suspension suture. The clinical and laboratory parameters available from the medical history were analyzed, X-ray passage, surgical complications, non-surgical complications, the length of hospitalization, the postoperative course, time of onset of postoperative complications, postoperative radiological follow-up and endoscopic postoperative follow-up were then analyzed. RESULTS: A total of 212 patients were included in the study: 87 in the experimental group with suspension sutures on the EJA and 125 in the control group without suspension sutures on the EJA. The two cohorts did not differ in other clinicopathologic parameters except perineural invasion, which was more prevalent in the control group. Patients in both groups were anemic and elevated values of C reactive protein (CRP) and decreased levels of proteins, albumin and globulin, with no significant difference between the two groups. The most common general complication was pleural effusion (28%), followed by pneumonia (∼22%). The most common complication in the experimental group was an intraabdominal abscess, while in the control group, it was a surgical wound infection. CONCLUSION: Our study did not show a statistically significant difference between the two analyzed EJA techniques created with a circular stapler, when it comes to postoperative course and outcome in patients with gastric cancer.
Deep-KEDI: Deep learning-based zigzag generative adversarial network for encryption and decryption of medical images
Authors: Selvakumar K. , Lokesh S.
Published: July 2024

BACKGROUND: Medical imaging techniques have improved to the point where security has become a basic requirement for all applications to ensure data security and data transmission over the internet. However, clinical images hold personal and sensitive data related to the patients and their disclosure has a negative impact on their right to privacy as well as legal ramifications for hospitals. OBJECTIVE: In this research, a novel deep learning-based key generation network (Deep-KEDI) is designed to produce the secure key used for decrypting and encrypting medical images. METHODS: Initially, medical images are pre-processed by adding the speckle noise using discrete ripplet transform before encryption and are removed after decryption for more security. In the Deep-KEDI model, the zigzag generative adversarial network (ZZ-GAN) is used as the learning network to generate the secret key. RESULTS: The proposed ZZ-GAN is used for secure encryption by generating three different zigzag patterns (vertical, horizontal, diagonal) of encrypted images with its key. The zigzag cipher uses an XOR operation in both encryption and decryption using the proposed ZZ-GAN. Encrypting the original image requires a secret key generated during encryption. After identification, the encrypted image is decrypted using the generated key to reverse the encryption process. Finally, speckle noise is removed from the encrypted image in order to reconstruct the original image. CONCLUSION: According to the experiments, the Deep-KEDI model generates secret keys with an information entropy of 7.45 that is particularly suitable for securing medical images.

Authors: Nasir Muhammad , Khusairi Abdullah
Published: July 2024

This article discusses the impact and challenges of Transnational Islamic groups on strengthening Religious Moderation in Indonesia in promoting a balanced, tolerant and peaceful understanding of Islam, both at the local and global levels. This article was written using the exposition report method which relies on the strength of the author's opinion in reviewing literature facts about Transnational Islam and Religious Moderation in Indonesia. The concepts of Transnational Islam and Religious Moderation in this article are positioned in a face-to-face relationship, where Transnational Islam is positioned as a challenge for strengthening Religious Moderation in Indonesia. This article concludes that Transnational Islamic Groups, which in terms of ideology and religious practices contain a spirit of religious exclusivism, exclusivism, and violent extremism, are a challenge to religious moderation in Indonesia. These three spirits were formulated by the religious moderation program with the abbreviation REEVE. Based on these three challenge formulations, it can be understood that Strengthening Religious Moderation as a public policy is the Indonesian government's response to exclusive, extreme and radical religious practices which have a negative impact on the harmonization of social life in society and at the same time endanger the integrity of the Republic of Indonesia.
