Malignant tumors of the pancreas are the fourth leading cause of cancer-related deaths. This is mainly because they are often diagnosed at a late stage. One of the challenges in diagnosing focal lesions in the pancreas is the difficulty in distinguishing them from other conditions due to the unique location and anatomy of the organ, as well as the similarity in their ultrasound characteristics. One of the most sensitive imaging modalities of the pancreas is endoscopic ultrasonography. However, clinicians recognize that EUS is a difficult and highly operator-dependent method, while its results are highly dependent on the experience of the investigator. Hybrid technologies based on artificial intelligence methods can improve the accuracy and objectify the results of endosonographic diagnostics. Endoscopic ultrasonogra-phy was performed on 272 patients with focal lesions of the pancreatobiliary zone, who had been treated in the surgical section of the Kursk Regional Clinical Hospital in 2014–2023. The study utilized an Olympus EVIS EXERA II video information endoscopic system, along with an EU-ME1 ultrasound unit equipped with GF UM160 and GF UC140P-AL5 echo endoscopes. Out of the focal formations in the pancreatobiliary zone, pancreatic cancer was detected in 109 patients, accounting for 40.1% of the cases. Additionally, 40 patients (14.7%) were diagnosed with local forms of chronic pan-creatitis. The reference sonograms displayed distinguishable focal pancreatic pathologies, leading to the development of hybrid fuzzy mathematical decision-making rules at the South-West State University in Kursk, Russian Federation. This research resulted in the creation of a fuzzy hybrid model for the differential diagnosis of chronic focal pancreatitis and pancreatic cancer. Endoscopic ultrasonography, combined with hybrid fuzzy logic methodology, has made it possible to create a model for differentiating between chronic focal pancreatitis and pancreatic ductal adenocarcinoma.

This work aims at improving the quality of health assessments, specifically under the influence of occupational risk factors. For this purpose, additional informative indicators are utilized in prognostic and diagnostic models. The models are used to characterize the level of body protection based on oxidative status. A quantitative method is proposed to assess the body’s level of protection by means of the levels of lipid peroxidation and antioxidant activity, which characterize the body’s oxidative status. A mechanism is developed for integrating the proposed method into prognostic and diagnostic decision rules. The developed rules are in the form of mathematical models used to synthesize hybrid fuzzy decision rules, which are then used to quantify the level of body protection (LBP) against external risk factors, based on the use of protection level functions in terms of lipid peroxidation and antioxidant activity. A mechanism for embedding LBP into predictive and diagnostic decision rules has been proposed. The proposed method is used to predict the occurrence and development of coronary heart disease in railroad locomotive drivers. It was found that to improve the predicting and diagnosing of diseases caused by external pathogenic factors, quantitative assessments of LBP, determined by oxidative status, can be implemented. It has been established that the use of the protection level indicator in predictive decision rules makes it possible to increase the efficiency of the prediction while simultaneously increasing its accuracy. © 2023 by Begell House, Inc.

The various parts of the palmyra and coconut trees which are widely distributed in the southern parts of the Indian subcontinent have been studied and utilized for many years. These contain a white and spongy edible component in them which is found during the germination of the seeds called haustorium. The palmyra and coconut trees each have different sections with special medical properties. Recently, the haustorium of both coconut and palmyra trees has been gaining increased attention from researchers due to its nutritional properties. Certain studies on the haustoria have revealed the presence of various compounds that are beneficial for human health. The bioactive compounds found in the previous studies include phenols, flavonoids, terpenoids, pyrimidine groups and certain vitamins which act as antioxidant, anti-inflammatory, anti-ulcer, anti-diabetic, anti-cancer, and anti-mutagenic agents. This review focuses on comparing the nutritional composition, bioactive compounds, sugar profile fatty acid profile, amino acid profile, minerals, and vitamins of both palmyra and coconut haustorium. This review also reports on the value addition of the haustoria as usually they are consumed in their raw form. These value-added products not only enhance the economic viability of these underutilized resources but also contribute to extending their shelf life, making them more accessible in the market. Also, this review emphasizes the haustorium's potential defence against negative consequences. Therefore, this review paper helps in understanding the palmyra and coconut haustorium and its potential health benefits. © 2024 The Author(s)

Micro, small, and medium-sized enterprises (MSMEs) across the globe have been the major victims of the COVID-19 pandemic, which has plunged the business world into a crisis. However, employee engagement (EE) has been labeled as an essential nutrient that organizations need in order to survive in these turbulent times. This study was to investigate the effect of EE on employee performance during the COVID-19 pandemic and how job demands and job resources moderate this relationship. A sample size of 395 respondents were selected from a variety of MSMEs via a convenience sampling method. The study used a survey questionnaire approach as the main method for collecting primary data. The result of the correlation analysis showed that there was a significant relationship between EE and employee performance. It was revealed that job demands and job resources moderated the relationship between EE and employee performance. Finally, the result showed that job demands had an insignificant effect on EE, but job resources had a significant effect on EE. Thus, it can be concluded that, in the face of COVID-19, EE is a significant predictor of EP in the MSME sector.

A new group of tributyloctylphosphonium-based ionic liquids containing several carboxylate anions was designed, prepared and physicochemically characterized. All phosphonium carboxylates obtained in this study became viscous liquids at room temperature. The formate-based ionic liquid exhibited the highest density and number density due to the smallest anion size. All ionic liquids exhibited typical ionic conduction behavior, since the viscosity decreased and the conductivity increased with increasing temperature. It was also found that the viscosity tended to decrease with increasing the carbon numbers of the alkyl chains of lower carboxylate anions. Compared to the propionate-based ionic liquids, lactate-based ionic liquids exhibited higher viscosity. The phosphonium ionic liquids based on carboxylate anions showed higher thermal stability than nitrogen-based counterpart ionic liquids. ©The Electrochemical Society.

引用

Agriculture and Food Security 2021年第1期10卷 9页

作者： Mabe, Franklin Nantui Mumuni, Eliasu Sulemana, Nashiru Department of Agricultural and Resource Economics Faculty of Agribusiness and Applied Economics University for Development Studies Tamale Ghana Department of Communication and Innovation Technology Faculty of Communication and Cultural Studies University for Development Studies Tamale Ghana Department of Agricultural Extension Rural Development and Gender Studies Faculty of Agribusiness and Applied Economics University for Development Studies Tamale Ghana

Background: Sustainable development Goal 2 aims at ending hunger, achieving food security, improving nutrition and promoting sustainable agriculture. Whilst some smallholder farmers are aware of this goal, others are not. The question that arises is whether or not awareness translates into food security. Therefore, this study assessed whether or not smallholder farmers’ awareness of Sustainable development Goal 2 improves household food security in the Northern Region of Ghana. Methods: The study used cross-sectional primary data collected from two districts and two municipalities in the region. An endogenous switching regression treatment effects model with ordered outcome was used to estimate the effects of smallholder farmers’ awareness of Sustainable development Goal 2 on household food insecurity level. Results: The age of household head, distance of households to the regional capital, membership of farmer-based organizations, access to e-extension, education, and ownership of radio are the key drivers of farmers’ awareness of Sustainable development Goal 2. The results from the endogenous switching regression treatment effects model with ordered outcome showed that households who are aware of the second goal are more food secure than their counterparts. Conclusions: It is therefore prudent for stakeholders promoting and championing Sustainable development Goals to educate farmers on goal 2 as their awareness of the goal is critical to achieving food security. © 2021, The Author(s).

Due to the influence of the global pandemic, online and distance learning has replaced traditional classroom and face-to-face interaction so students can continue learning. Internet mediated self-directed learning also climbed to a new height and foreign language learning from YouTube video is a very popular learning method for many. Furthermore, YouTube videos can supplement cross-cultural knowledge for foreign language (FL) learners, which is a critical yet hard to develop ability for FL teachers. However, unlike for FL textbooks, the cross-cultural elements have not been examined thoroughly for YouTube videos. Therefore, this study analyzed the most subscribed and watched Japanese Chinese-as-FL YouTuber, "Lee Sisters ch", which is also the official representative of HSK (Hanyu Shuiping Kaoshi) test. We selected 30 most watched videos and analyzed their contents according to Chastain’s Big ‘C’ small ‘c’ culture framework. The result showed 86.67% of the most popular 30 videos covered topics about culture: 23.33% of the videos were related to big ‘C’ culture and 63.33% were about small ‘c’ culture. Similar to earlier researches on FL textbooks, "Literature" was the main theme of big ‘C’. On the other hand, "Everyday living" was the most frequent small ‘c’ topic, which is a unique phenomenon for YouTube FL channels. Furthermore, not only did the portion of big ‘C’ and small ‘c’ cultures match the suggestions of FL scholars, the language used in all videos were also mainly in Japanese that fit the needs of Japanese CFL learners. It is concluded YouTube video may be suitable to learn cross-cultural knowledge for FL learner, especially for Japanese students. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The spread of the Metaverse has created new moral and legal challenges, especially when it comes to protecting against fraud. This study explores the legal complexities surrounding Ethereum-specific metaverse transactions and provides guidance on how to identify and address fraudulent activity. The focus of this investigation is the field of fraud detection in the Ethereum environment. Current methods of detecting fraud, such as Blockchain analysis and machine learning-based algorithms, are carefully examined. Next, a new approach to fraud detection is put out, which is predicated on a collection of seven machine learning algorithms: K-Nearest Neighbours (KNN), Decision Tree, Support Vector Machine (SVM), Random Forest, KNN, XGBoost (XGB), and Artificial Neural Network (ANN). The results of this study are carefully outlined, demonstrating the accuracy, recall, F1 score, and precision that each of the previously listed algorithms demonstrated. Moreover, this article lays out possible directions for further research, including the incorporation of group approaches and the investigation of creating characteristics to strengthen fraud detection abilities. This academic paper provides a significant and novel insight into the identification of fraudulent activity in Ethereum transactions, highlighting the potential benefits of using machine learning algorithms for this kind of discernment.
