In order to study academic performance, dropout, and enrollment breakdown in higher education, attention is generally focused on the socioeconomic aspects and family environment of the students, resorting to hypotheses and explanations of a complex situation and analyzing external variables that influence on student behavior. This presentation analyses the resilience of university students in the first years of UNaM faculties, namely Bachelor of Business Administration (LAE), Bachelor of Economics (LE) and Certified Public Accountant (CP) of the Faculty of Economics (FCE), as will be described in the body of the text. Using online surveys, qualitative features of the group were delineated regarding the topic of interest and quantitative parameters were obtained to describe its demographic characteristics. The results show that the students perceive themselves as highly resilient, they state that they usually find a way out of a difficulty, they maintain their interest, they feel friends with themselves and they question themselves about the relevance of the contents that make up the curricula of the subjects they study. To a large extent, the lack of equanimity is a characteristic that would define these students.

Virtual Reality (VR) technology provides the sensation of immersion in virtual digital spaces, through interactions that occur in different dimensions of perceptions. Considering the lack of research involving VR in evaluations of Human Computer Interaction (HCI), Emotional Design, and User Experience, the present study aimed to investigate the state-of-the-art in this subject. For this, a systematic literature review was carried out. The question to be answered is: How do users change behavior in visual interaction with different artifacts in real and virtual environments and how that influences the perception (emotional, semantic, and usability) of individuals? Structured analyzes were applied to scientific articles that address the experience of healthy adult participants and their interaction relationship with environments and artifacts immersed in VR. After screening and in-depth reading steps, 27 articles were selected for meta-analysis discussions. The results point to the existence of a scientific gap since the works found and analyzed only partially answered the research question, which, because of this, may indicate an open field for studies involving VR This technology can be a viable tool with potential of assisting and complementing the methodological processes already consolidated in the Design and Human Factors areas.

Yerba mate is cultivated in northeastern Argentina, southern Brazil, and southeastern Paraguay. Agricultural technology, industrial pollution, geological sources, and food processing are the most prominent sources of food contamination by toxic elements, including heavy metals. The objective of this work was to evaluate the influence of soil acidity and fertilization practices in Misiones on Pb, Cd, and As content in soil samples and yerba mate plantations. Chemical analyses were performed by ICP-MS, after microwave acid digestion. Determinations made according to soil acidity indicate that there are differences between areas and between plant fractions on Pb, and Cd content of plantations. Determinations made according to fertilization system, areas and level of fertilization do not have a significant effect on Pb, Cd, and As plantations content. Given that these elements are toxic and that maximum contents in yerba mate are regulated, it is important to study mitigation measures so that plants do not accumulate them in excess in their tissues.

Ilex paraguariensis St. Hil. is a dioecious tree native to the subtropical forests of South America, whose leaves and small branches are processed to prepare the stimulating and popular infusion known as “mate”. On the basis of the exploration, from the transcriptomic, genomic and phylogenetic perspective of the xanthine biosynthetic pathway, it was possible to discover pseudogenes through comparative analysis with other plants of agronomic importance. The transcripts of I. paraguariensis were analyzed using the elite material developed by INTA EAA-Cerro Azul de Misiones as reference genome and the data provided from the transcriptome sequenced by Debat et. al in 2014. A phylogenetic examination of enzymes from a large family of SABATH genes that catalyze the methylation of oxygen atoms of a wide variety of carboxylic acids was performed. The most recently evolved genes of the SABATH family are those corresponding to the Xanthine Methyltransferases (XMT) and Caffeine Synthase (CS) pathways. Investigating the different types of methyltransferases that yerba mate presents in the metabolic process of caffeine conversion, several SABATH enzymes were categorized, of which three corresponded to pseudogenes within the caffeine synthase group.
Ilex paraguariensis St. Hil.是一种雌雄异株树，原产于南美洲的亚热带森林，其叶子和小树枝经加工后可制成刺激性强且广受欢迎的 "马黛茶"。在对黄嘌呤生物合成途径的转录本组、基因组和系统发育进行探索的基础上，通过与其他重要农艺植物进行比较分析，发现了假基因。以 INTA EAA-Cerro Azul de Misiones 开发的精英材料为参考基因组，并利用 Debat 等人在 2014 年测序的转录组提供的数据，对帕拉瓜里ensis 的转录本进行了分析。在研究耶巴马黛茶在咖啡因转化代谢过程中呈现的不同类型的甲基转移酶时，对几种 SABATH 酶进行了分类，其中三种对应于咖啡因合成酶组中的假基因。

Given the need to satisfy the demand for fish consumption, canned native fish has emerged as a market alternative, but it is necessary to determine the nutritional aspects of this product. The aim of this study was to characterise the lipid profile and evaluate the nutritional quality of matrinxã preserved in vegetable oil and compare these results with freshwater sardines obtained from the same type of processing and canning. Matrinxã species had higher protein content than sardines, but sardines had higher levels of moisture, lipids and total minerals. The predominant fatty acid in the canned fish samples was linoleic acid, followed by oleic acid and palmitic acid. In terms of nutritional quality, matrinxã showed higher indices of atherogenicity and thrombogenicity and lower values of the following ratios: hypocholesterolemic and hypercholesterolemic fatty acids; polyunsaturated/saturated and omega 6/omega 3 ratio in relation to sardines. In view of the results, it can be affirmed that Matrinxã, from a nutritional point of view, presents itself as a good alternative for the canned fish industry.

In the investigation, an analysis was carried out on the importance of the biological activity of Lemongrass (Cymbopogon citratus), its benefits and application in the food and non-food industry. The objective was to identify, analyze, organize and compare the information on the bioactive components of the plant species in the industry. The method used is exploratory with a documentary approach of secondary order, since a detailed search of bibliographic information of documents obtained in scientific bases that support the work was carried out. 8 bioactive components and 11 constituents of essential oils were determined, in relation to their use in industry, 2 applications were determined: in food used in beverages (energizing, moisturizing, functional) and as a food additive (antioxidants, preservatives and flavorings) and in the non-food area in the agricultural area (insecticide, fungicides and herbicide), in the cosmetics area (perfume, deodorants and shampoos) and in the pharmacological area (antibacterial and antifungal). The Cympogon citratus for its biological components has been used in the industry during the last years, in the non-food field. Myrcene, citronella, citronellol and geraniol are the components that are most used in the non-food area and citral is the bioactive that is used in the food part.

The incorporation of probiotic bacteria in pea-based products can encourage the consumption of this legume, contributing to the production of functional foods. The objective of this work was to develop pea-based antipasto, enriched with the probiotic Lactiplantibacillus plantarum, as well as to evaluate the microbiological quality and sensory characteristics of the product. The prepared antipasto contained peas, olive oil, onion, salt and oregano. After preparation, the addition of probiotic bacteria was performed and the product was kept refrigerated at 8 °C to carry out analyzes of filamentous fungi and yeasts, Enterobacteriaceae and Escherichia coli and sensory attributes of appearance, aroma, flavor and texture by 50 consumers not trained. Analyzes were performed at times 0 and after 14 days of product storage. The results of filamentous fungi and yeasts, Enterobacteriaceae and E. coli were satisfactory and the product was safe for consumption. Average scores ranging from 7.0 (I liked it moderately) to 8.0 (I liked it a lot) were attributed to the attributes evaluated in the sensory analysis. The antipasto showed good purchase intention, demonstrating high market potential. The pea is a promising alternative for the elaboration of probiotic non-dairy products with functional appeal, and can be inserted in food preparations.

Argentina suffers from an epidemic of non-communicable chronic diseases and a population with cardiovascular risk factors, particularly obesity. In this work, the cardiovascular risk in obese children and adolescents who attended a level III hospital in the city of Posadas, between September 2018 and January 2020, was studied. Eightyone patients were included, age 10 (2-15) years; 51% female. Body mass index was calculated, blood pressure was measured and serum HDLc, LDLc, triglycerides and glucose were determined. A questionnaire was completed on family history of cardiovascular disease, physical activity, tobacco and alcohol consumption. The presence of metabolic syndrome (SAP) according to Argentine Pediatric Society criteria and cardiovascular risk (Alustiza´s score) were identified and the relationship between them was established. Results: severe obesity: 43 (53%) patients; biochemical or clinical family history 27 individuals (33%); insufficient physical activity: 57 (70%) patients; tobacco and/or alcohol consumption: absent; blood pressure >p95: 11 individuals (14%). Fifty one patients (63%) had some dyslipidemia, 4 (5%) had hyperglycemia; metabolic syndrome was observed in 26 (32%) and 25 (31%) at medium/high cardiovascular (CV) risk. No association was found between CV risk by Alustiza score and metabolic syndrome. Since the pediatric population has cardiovascular risk factors and components of metabolic syndrome, it is important to search for and validate scores to measure this risk.

Fifty one patients (63%) had some dyslipidemia, 4 (5%) had hyperglycemia; metabolic syndrome was observed in 26 (32%) and 25 (31%) at medium/high cardiovascular (CV) risk.\u0000 No association was found between CV risk by Alustiza score and metabolic syndrome.\u0000Since the pediatric population has cardiovascular risk factors and components of metabolic syndrome, it is important to search for and validate scores to measure this risk.","PeriodicalId":21243,"journal":{"name":"Revista de Ciencia y Tecnología","volume":"428 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138991217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
