Familia oyente, hijos silentes: aproximaciones a la sexualidad en adolescentes sordos
Authors: Castellanos García Gloria Esperanza , Arenas Andrea del Pilar , Mayorga Ortegón Ángela Ivethe , Méndez Castro Carlos Andrés
Published: May 2023

El artículo muestra los resultados de la fase cualitativa de un proceso de investigación mixta, de tipo explicativo secuencial, que tuvo como objetivo indagar los factores familiares que inciden en la educación sexual de los adolescentes sordos y su influencia en los procesos de interacción socioafectiva. Se contó con la participación de diez adolescentes y sus padres, a quienes se les aplicó una encuesta y una entrevista semiestructurada. Los hallazgos evidencian una limitada concepción de la sexualidad por parte de los adolescentes, centrándose exclusivamente en el sexo y la genitalidad, y siendo la comunicación el factor familiar que más incide en el abordaje del tema entre padres oyentes e hijos sordos debido a la discontinuidad lingüística que caracteriza su dinámica. Para comprenderla, se hizo necesaria la intervención de un modelo lingüístico que, a partir de extensiones, llevara a comprender a los adolescentes las diferencias entre sexualidad, sexo e interacción socioafectiva.

Climatic conditions and habitats in Belső-Somogy, Külső-Somogy and Zselic as vegetation-based landscape regions III. Temperature envelopes of mesic deciduous woodlands
Authors: Salamon-Albert Éva
Published: May 2023

In our study distribution response to climatic temperature of mesic deciduous woodlands (lowland pedunculate and sessile oak-hornbeam woodlands, beech woodlands) are discussed in the relation of vegetation based landscape regions of South Transdanubia, including Belső-Somogy, Külső-Somogy and Zselic. Selected bioclimatic variables are used to characterize and compare climate envelopes of the habitats by their occurrence. Gaussian probability curves were fitted for yearly, quarterly and some short time range or variability of temperature indexes, representing annual trends, seasonality and extreme or limiting environmental factors in order to generate more biologically meaningful variables. Mesic deciduous woodlands (K) are accurately integrated into the regional habitat envelope (Á-NÉR), according to multipeaks of temperature indices. Among temperature variables, mean annual temperature and maximum one of warmest month is not relevant for habitat differentiation in any way. Mean temperature variables (BIOCLIM-6, -8, -9, -11) are resulted a moderate shifting in the realised range of habitat envelopes in case of pedunculate oak-hornbeam woodlands (K1a) especially, but not in case of sessile oak hornbeam woodlands (K2) and beech woodlands (K5). Separation of pedunculate oak-hornbeam woodlands is well represented by the range and seasonal variables (BIOCLIM-2, -4, -7). This habitat type tolerates high range of diurnal temperature, but a lower one of yearly extremities, as seasonality and annual difference. The most significant temperature effect in the existence of pedunculate oak-hornbeam woodlands is high mean diurnal range as a temperature hardiness and high mean temperature of coldest quarter as a themal limitation.

Authors: Kevey Balázs
Published: May 2023

The Zákány Hills are situated along the Dráva River in southwestern Hungary, where I collected 10 vegetation samples and studied the phytosociological characteristics of the riparian hardwood forest (Knautio drymeiae-Ulmetum). Its strongly fragmented stands occur primarily on the riverside foothills, where the thick gravel deposit is covered with a shallow layer of loess. These forest fragments are in contact most often with alder gallery forests (Carici pendulae-Alnetum) and oak hornbeam forests (Anemoni trifoliae-Carpinetum). The stands host some herbaceous species (Anemone trifolia, Lamium orvala) that occur nowhere else in the country and indicate sub-Mediterranean and Illyrian influences.

Authors: Péntek Attila László , Vad Csaba Ferenc , Horváth Zsófia
Published: May 2023

Between March and June 2012, we studied the presence of amphibian species in more than 100 waterbodies of the Tolna-Baranya Hills and the Eastern Mecsek. We included lakes, ponds, temporary pools, marshes as well as streams in our survey and considered all developmental stages of the inhabiting species. We found nine amphibian species in the whole territory. The two most common species were the water frog complex (Pelophylax esculentus complex) and the agile frog (Rana dalmatina). One of our most important results was proving the occurrence of yellow-bellied toad (Bombina variegata) in the Szekszárd Hills. The amphibian fauna was lesser-known in this region, thus our results are important for both biogeography and nature conservation.
A Zákányi-dombok égeres mocsárerdei [Angelico sylvestri-Alnetum glutinosae Borhidi in Borhidi & Kevey 1996]

Published: May 2023

We present in this paper the phytosociological analysis of 50 samples of peat deficient alder swamps (Angelico sylvestri-Alnetum glutinosae) found in the Zákány Hills along the Drava river in southwestern Hungary. Most of these swamps are found on nutrient-rich alluvial soil along the Visszafolyó stream. The species composition of them does not show signs of sub-Mediterranean and Illyrian influences, which generally are characteristic of the Zákány Hills. Instead, it is characterized by the occurrence of a number of regional rarities, such as Alnus incana, Cardamine amara, Carex elongata, C. pseudocyperus, C. rostrata, C. strigosa, Doronicum austriacum, Dryopteris carthusiana, D. dilatata, D. expansa, Equisetum hyemale, Geranium palustre, Leucojum aestivum, Peucedanum palustre, Ranunculus lingua, Ribes rubrum, Rubus idaeus, Scilla drunensis, Thelypteris palustris, Veratrum album. The stands are somewhat related to alder gallery forests (Carici pendulae-Alnetum glutinosae), but are more closely related to typical alder swamps (Carici elongatae-Alnetum glutinosae). As an associastion, it is classified in the suballiance Scirpo sylvaticiAlnenion glutinosae Kevey 2008a.
Climatic conditions and habitats in Belső-Somogy, Külső-Somogy and Zselic as vegetation-based landscape regions IV. Precipitation envelopes of mesic deciduous woodland
Authors: Salamon-Albert Éva
Published: May 2023

In our study precipitation response of mesic deciduous woodlands (lowland pedunculate and sessile oak-hornbeam woodland, beech woodland) are discussed in the vegetation based landscape regions of South Transdanubia, including Belső-Somogy, Külső-Somogy and Zselic at landscape scale. Long term precipitation variables from BIOCLIM series as potential ecological predictors are used to characterize and compare climate envelopes of selected mesic woodlands. Non-parametric Gaussian probability estimation detailed with kernel densities as a potential series of ecological niches were computed for yearly, quarterly and some short time range or deviation of precipitation representing annual trends, seasonality and extreme or limiting environmental factors in order to get more extensive knowledge about macro-ecological responses leading to environmental adaptation. Precipitation envelopes of the woodlands as the whole and the habitats in each are nearly integrated into the regional range according to their summarized densities on relative frequency. Precipitation response of beech woodlands shows significant difference to semi-natural habitats by all variables consequently but to habitat group of mesic woodlands only in some case (e.g. annual sum of precipitation). Climate envelope of pedunculate oak-hornbeam woodlands and sessile oak-hornbeam woodlands significantly differ from semi-natural habitats response by precipitation of wettest and coldest quarter, especially. Among studied variables the annual sum and one of the warmest quarter turned to be the most effective in climatic niche differentiation in habitat group of woodlands as a whole as well as in mesic habitat types in each. In contrast to the above mentioned, fall sum of wettest month and precipitation seasonality is verified to provide the most slight niche segregation effort. The two latter ecological phenomena is suitable to discover the most significant macro-ecological factors to enchance functional diversity [BIOCLIM-12, -18] or variables to confirm a nearly uniform precipitation performance [BIOCLIM-13, -14] in submontaine mesic woodlands as the main macroecological predictors for water input.

Published: May 2023

Sudden cardiac arrest is a leading cause of death in Europe. High-quality cardiopulmonary resuscitation (CPR) and guidelines compliance of rescuers have been associated with better outcomes after cardiac arrest. However, wide variability in attempting bystander CPR manoeuvres has been reported. Educational programmes for teaching CPR to medical students and fellows are highly advisable in this context. However, there is no homogeneity regarding the CPR education offered by academic institutions. We surveyed 208 Italian medical students and 162 fellows in cardiology regarding the educational offer and needs in CPR. Among the 11 medical schools surveyed, 8 (73%) offer basic (BLS) courses but only 3 (38%) with formal certification of ‘BLS provider’, while none offers advanced (ACLS/ALS) courses. Among the 30 specialization schools in cardiology surveyed, 10 (33%) offer a BLS course (6 with formal certification of ‘BLS provider’), and 8 (27%) offer an ACLS/ALS course (5 with formal certification). Only a minority of students and fellows perceive themselves as highly proficient either in BLS or ACLS/ALS, although most of the fellows were involved at least once in rescuing a cardiac arrest.

The present position paper analyses and suggests the strategies that should be adopted by Italian medical and specialization schools to spread the CPR culture and increase the long-standing retention of CPR-related technical and nontechnical skills.

The recent pandemic has substantially changed the approach to the prevention of cardiovascular diseases in women. Women have been significantly impacted by the changes that occurred during the pandemic and the quarantine adopted to prevent the spread of the disease. Changes involved prevention both through the reduction of visits and preventive screening and through social and economic changes. It is necessary to adopt new cardiovascular prevention approaches focused on returning to healthy lifestyles, reducing stress and depression also using modern tools such as telemedicine, mobile phone applications and the web. These tools convey messages in a persuasive way especially in young and adult women. There is less impact of these new tools on older women towards whom it is important to adopt a more traditional approach. This review focuses on the new approach to cardiovascular prevention in women in light of the lifestyle changes recorded during the pandemic and which led to an increase in obesity examines the effects on the cardiovascular system induced by stress and depression and analyses the new high blood pressure guidelines and indications that are specific to women.

Prevention and effective treatment of cardiovascular disease are progressive issues that grow in tandem with the average age of the world population. Over recent decades, the potential role of artificial intelligence in cardiovascular medicine has been increasingly recognized because of the incredible amount of real-world data (RWD) regarding patient health status and healthcare delivery that can be collated from a variety of sources wherein patient information is routinely collected, including patient registries, clinical case reports, reimbursement claims and billing reports, medical devices, and electronic health records. Like any other (health) data, RWD can be analysed in accordance with high-quality research methods, and its analysis can deliver valuable patient-centric insights complementing the information obtained from conventional clinical trials. Artificial intelligence application on RWD has the potential to detect a patient's health trajectory leading to personalized medicine and tailored treatment. This article reviews the benefits of artificial intelligence in cardiovascular prevention and management, focusing on diagnostic and therapeutic improvements without neglecting the limitations of this new scientific approach.

Background: Cystic fibrosis was considered a fatal condition years ago but, nowadays, it can have a favorable evolution if diagnosed and treated early.

Objective: Screening clinical aspects of patients suspected for cystic fibrosis and later diagnosed by means of specific sweat and genetic tests.

Methods: A retrospective descriptive study was performed on 13 patients during five years, between 2015-2020 from the Pediatric Clinic of the Emergency County Hospital in Constanta.

Results: There were five patients present in ΔF508 homozygous form, which it seems to be the most frequent mutation, translated by the deletion of phenylalanine at position 508. Among the heterozygous patients, 2 patients aged 10 and 14 years have the ΔF508 del 2.3 mutation; a 10-year-old patient has the mutation ΔF508, 2183 AA>G; a 7-year-old patient has the ΔF508 R553X mutation; a 7-year-old patient has the N1303K, 394del TT mutation; a 1-year-old patient is heterozygous for the 394del TT and R347P mutations, a 3-year-old patient has the compound mutation ΔF508del and R334W, and finally, we find a 2-year-old patient heterozygous for the Δ508 mutation. Ten from 11 patients were diagnosed in the first year of life by performing the sweat test, and 2 patients based on the genetic test. In 30% of cases the onset manifestation were represented by diarrhea and growth failure, and 38% of cases had added respiratory manifestation. Singular manifestations such as respiratory disease, or respiratory disease accompanied by loss of appetite and growth failure, or chronic cough and steatorrhea followed by growth failure occurred in 8% each.

If not properly diagnosed and treated, cystic fibrosis can put the patient’s life at risk. The analysis between an early diagnosis and the decrease of the incidence in pulmonary complications with pathogenic agents was statistically significant.

Published: May 2023

It is well known that vitamin D’s general immunomodulatory actions are helpful in viral infections and that a shortage is linked to a more serious prognosis for Covid-19. In this sistematic review, we examined the existing literature on evidence as to whether there is also link between vitamin D range levels in pediatric population and the outcome of the Covid-19 infection. We looked for studies that measured vitamin D blood concentrations and examined the effects of vitamin D supplementation in young infected patients. Vitamin D may decrease the risk of respiratory infections in a number of ways through its interactions with numerous cells, including by decreasing viral survival and replication, reducing the cytokine storm, raising angiotensin-converting enzyme 2 concentrations (ACE2) while not damaging the endothelial integrity. The incidence or severity of Covid-19 is linked with blood 25-hydroxyvitamin D concentrations, according to many observational studies. However experimental verification is still needed. Given their safety and broad therapeutic window, vitamin D supplements seem to be an effective way for individuals and doctors to prevent or treat Covid-19. Nonetheless, the outcomes of significant vitamin D randomized controlled trials are further needed.

Published: May 2023

MANET is an autonomous wireless network without any centralized authority, consisting of a dynamic topology with a multi-hop scenario. Clustering provides centralized authority within MANET and makes the network stable up to some extent. Security is one of the most challenging aspects, directly proportional to load and overhead over the network. The model being proposed uses a cluster-based technique and modified secure routing protocol, which minimizes the network’s load and overhead, improving the network’s security and performance. Two major factors are used as contribution level and stability factor for the choice of cluster head, which minimizes the method of re-selection for cluster head. The node addition using authentication and the Modified Secure Routing Protocol increases the security of the network. The Modified Secure Routing Protocol, based on limited and efficient use of the certificates with encryption and decryption of packets, minimizes the overhead and load over the network. Hence, it provides more efficiency and security.

Authors: Sultan Wisam Hulail , Hamza Dina Mukheef
Published: May 2023

The research includes a new model proposed for the stress-strain relationship of unconfined concrete in compression valid for normal and high strength concrete. A wide range of experimental data with varied lab circumstances has been used for fitting and other data for verifying the model. It is noted that the current model has a good agreement with the experimental data for both its ascending and descending branches in normal and high strength concrete depending on the mean of average values of experimental to calculated stresses, coefficient of variation, and difference ratio. Where values of the average experimental to calculated stresses ranged from 0.723 to 1.354 for 38 samples with a mean of 0.994, while the coefficient of variation values ranged from 16.099 to 48.562 with a mean of 27.704 % for these specimens. Also, difference ratio values ranged from 0.86 % to 31.804 % with a mean of 9.009 % for these specimens. The model gives the best results in comparison with other models.
Stability of the Čachtice Underground Corridors
Authors: Bulko Roman , Mužík Juraj , Gwóźdź-Lasoń Monika , Juraszek Janusz , Segalini Andrea
Published: May 2023

At the beginning of the 16th century, the original inhabitants of Čachtice built a large complex of tunnels and cellars under the village, today called the Čachtice underground. The underground protected people from war conflicts, most recently during World War II, as anti-aircraft shelters. Over time, the underground lost its significance. The corridors were walled up, covered with rubble, and collapsed due to construction work. Later, a part of the underground was repaired, and historical events occurred in such a preserved part. Due to a lawsuit, the Čachtice underground was eventually closed to the public, and it was necessary to test the stability of the walls of the Čachtice underground. A 3D model of the underground was created, and three areas were identified in which numerical calculations were performed in Plaxis 2D software. The whole underground is located in loess soil. The Čachtice underground is stable if the conditions do not change diametrically. The calculated factors of safety support this assumption.

Published: May 2023

In this research article effect of steel fibers on workability and compressive strength of recycled aggregate concrete is presented. Recycled aggregates from demolished waste were used in equal proportion with conventional aggregates. Steel fibers of 1 mm diameter and 25 mm length were used. For preparation of concrete 1:2:4 mix with 0.55 water-cement ratio was used. Workability of each mix was checked by slump cone test. Total of 40 samples were prepared in standard way and cured for 28 days. All the specimens were tested for maximum load in universal testing machine under gradually increasing load at the rate of 0.5 kN/sec. Recorded load was converted into compressive strength. The obtained results showed that slump of the concrete decreased with increase in the dosage of the steel fibers than conventional concrete. Compressive strength was observed 15% and 34% higher than the compressive strength of conventional and recycled aggregate concrete at the steel fiber dosage of 3%. It is evident that although addition of recycled aggregates in concrete reduces the compressive strength but binary blending with steel fibers not only overcomes this loss but shows strength gain with increase in the dosage of the fibers.

Published: May 2023

Abandonment of agricultural fields triggers the ecosystem recovery in the process referred to as secondary succession. The objective of this study was to find the impact of secondary succession during 12 years lasting abandonment of agricultural fields with loamy sand and sandy loam soils on soil properties, namely soil organic carbon content, pH, water and ethanol sorptivity, hydraulic conductivity, water drop penetration time (WDPT), and repellency index (RI). The method of space-for-time substitution was used so that the fields abandoned at different times were treated as a homogeneous chronosequence. The studied soils showed a permanent increase in WDPT and a monotonous decrease in pH and water sorptivity with the duration of field abandonment. The dependence of the other characteristics on the duration of field abandonment was not unambiguous. The ethanol sorptivity decreased between 0 and 8 years of field abandonment, and increased between 8 and 12 years, when it copied a similar course of sand content during abandonment. The hydraulic conductivity halved within the first eight years of field abandonment and then increased statistically insignificantly between 8 and 12 years of abandonment. The repellency index decreased statistically insignificantly between 0 and 8 years of abandonment and then increased between 8 and 12 years.
New methodological approach to characterize dryland´s ecohydrological functionality on the basis of Balance between Connectivity and potential Water Retention Capacity (BalanCR)
Authors: Rodríguez-Lozano Borja , Martínez-Sánchez Juan , Maza-Maza Jaime , Cantón Yolanda , Rodríguez-Caballero Emilio
Published: May 2023

Drylands are ecohydrologically-coupled ecosystems whose functioning depends on the interplay between hydrological connectivity between runoff source areas and the capacity of vegetation to retain water fluxes and associated resources. In this study we present a new easily applicable methodology for the ecohydrological characterization of dryland ecosystem functioning grounded in the balance between these two strongly interrelated processes using easily obtainable remote sensing data (e.g. UAV and SENTINEL-2 images), the BalanCR method (Balance between Connectivity and potential Water Retention Capacity). This methodology was first tested on synthetic hillslopes representing different configurations of the patchy and heterogenic distribution of vegetation in drylands. The analysis of these synthetic vegetation spatial patterns involving different vegetation patch densities, sizes, and fractional coverage values showed that BalanCR properly characterizes the expected ecohydrological interactions between potential conditions of runoff connectivity and water retention by plants operating in drylands. In a second step, we applied the BalanCR method on four semiarid hillslopes along an altitudinal aridity gradient covered by Mediterranean alpha steppes at very detailed spatial resolution (0.2 m) and at medium resolution (10 m). The obtained results were validated based on soil moisture data and vegetation greening and clearly recognized the four study sites as functional ecosystems, with very low water resource losses, and a pattern of increasing water redistribution processes as vegetation coverage declines. However, the sensitivity of methodology depends on the resolution of the input data (vegetation map and Digital Elevation Model; DEM), and the expected positive effect of small vegetation structures (vegetation patches smaller than the pixel size) on water redistribution is underestimated. Even in this case, the functionality and connectivity of the analyzed sites is correctly characterized as ecosystems showed similar values of both components for the methodology BalanC (hydrological connectivity component) and BalanR (potential water retention capacity component) than those obtained at very detailed scale, with a similar pattern of water allocation values in response to increased aridity. Thus, the proposed metric represents a promising tool for the proper evaluation of dryland conditions and to incorporate hillslope processes in climate change models, which is one of the main gaps to better understand the drylands response upon ongoing climate change.
Academic Identity, School Belongingness, Athletic Identity, and Athletic Expectations as Predictors of Academic and Athletic Time Use of College Athletes
Authors: Santos Jay C. , Sagas Michael
Published: May 2023

Time demands are among the primary challenges for college student-athletes. They have to attend to classes and study halls as well as athletic-related activities such as training and competition. Both academic and athletic tasks require tremendous amount of time. Thus, it is argued that academics and athletics compete for the student-athletes’ attention. This research examined the impact of academic and athletic factors on student-athletes’ time use in academics and athletics using a subset of the 2015 United States National Collegiate Athletic Association (NCAA) GOALS data. The relationships of academic identity, school belongingness, athletic identity, and athletic expectations with academic time use and athletic time spent were tested. Differences on the variables of interest according to race, gender, and division level were also investigated. Our findings revealed that academic identity is a positive predictor of academic time use and a negative predictor of athletic time use, while athletic identity is a positive predictor of athletic time spent. We also determined a contrasting influence of athletic expectations in time commitments. Lastly, we likewise found significant effects of race, gender, and division level on the academic and athletic engagements of college athletes.

Performance management, as a systematic and continuous process of planning, measuring and improving performance, is an important endeavor for any organization, regardless of being private or public. To understand the current state of research on performance management, a comprehensive bibliometric study was conducted. This paper aims to provide a co-occurrence analysis to identify and explore clusters, prevailing and emerging themes, and future research directions. For this purpose data was collected from the WoS database and processed with VOSviewer and Microsoft Excel. The paper contains visual representations of clusters, keywords and their relationships, as well as an analysis of the novelty of the concepts. Based on the average published year (APY), the hottest keywords identified are Covid-19 (APY: 2021), followed by Industry 4.0 (APY: 2020.17), together with other 4IR tools (big data analytics, big data, machine learning, artificial intelligence, cloud, Iot, etc.). Resulting from the analysis of concepts with APY after 2017, in terms of their representativeness (occurrence), links, and total link strengths (TLS) with other items from the map, three concepts significantly emerged: framework (Cluster 1); public sector (Cluster 3); sustainability (Cluster 4). Based on the overall findings, new research directions were proposed.

According to the traditional know-how, the Northern wild pineapple (Pandanus tonkinensis) has been used efficiently as a major component of oriental remedies for liver protection. Based on the experimentally found chemical composition of Pandanus tonkinensis and their obtained biological activities in terms of the hepatoprotection purpose, two structure-elucidated compounds pinoresinol 4-O-beta-D-glucopyranoside and vladinol F were selected as potential markers for this medical plant. This paper is aiming to present the validation of proposed HPLC method for simultaneous quantification of the both pinoresinol 4-O-beta-D-glucopyranoside and vladinol F in the fruits of Pandanus tonkinensis with the following conditions: using RP-C18 (250 mm × 4.6 mm; 5 μm) column, detection wavelength measured at 228 nm, the mobile phases consisting of acetonitrile and 0.1% acetic acid in gradient mode with a flow rate of 1mL/min and injection volume was 10 mL. Method validation showed a high specificity, linear calibration ranging from 25.5 to 76.4 mg/ml (r= 0.9991) and from 26.0 to 77.9 mg/ml (r= 0.9987) for two markers, respectively. Besides, a good repeatability and intermediate precisions (RSD < 2%), a reliable accuracy (recovery efficiency between 99.4 and 101.5%, RSD < 1.73%) as well as the obtained limits of quantification in values of 2.55 m/g and 2.60 mg/g for the two mentioned markers were received. Using the above validated method, the content of two markers - pinoresinol 4-O-beta-D-glucopyranoside and vladinol F in Pandanus tonkinensis fruits collected from different locations (Thanh Hoa, Hoa Binh, Thai Nguyen) had been determined falling in the range of 0.0250 - 0.0435 mg/g and 0.0243 - 0.0371 mg/g, respectively.

Published: May 2023

Watering and fertilizing are very important to maintain the quality of the oil palm seeds. If the oil palm seeds are not watered regularly the soil will dry out while the oil palm seeds generally need to maintain adequate soil moisture and require a loose textured soil medium. So far, farmers have not optimally fulfilled the needs for water and fertilizer for oil palm seeds because they still use manual and traditional methods. Technological developments have made it possible to create irrigation and fertilization techniques automatically. In this study, a prototype of an automatic watering and fertilizing system was designed and realized for oil palm seedlings using the NodeMCU ESP8266 as the main controller in addition to RTC, humidity sensors, relays, water pumps, LCDs, and smartphones. RTC is used for fertilization scheduling, humidity sensors to sense soil moisture levels, relays as automatic switches that turn on and off pumps, water pumps to pump water and liquid fertilizer, LCD to display information, and smartphones to monitor conditions and processes of watering and fertilizing coconut seedlings palm. The test results show that the prototype tool can work well. When the soil moisture is read by the humidity sensor less than 30% (dry soil condition) then pump one is activated and when the soil moisture is more than 60% (wet soil condition) then pump one turns off. Furthermore, fertilization can take place according to a predetermined schedule where the second pump will automatically activate with a duration of 20 seconds for each fertilization period.

Published: May 2023

Soybean is a source of vegetable protein that is rich in nutrients and a source of producing anticancer bioactive peptides. This study aims to determine the optimum conditions for hydrolysis of soybean protein with papain enzyme and their cytotoxicity against the MCF-7 cells. Soybean protein was isolated using an acid precipitation technique. Then, the protein isolate was hydrolyzed using papain enzyme with variations of papain concentration 0,5; 1; and 5% (v/v) and variations of incubation time 0, 1, 2, 3, and 4 hours at 50 °C. The hydrolysates were tested for their degree of hydrolysis (%DH), molecular weight profile using SDS-PAGE, and cytotoxicity against the MCF-7 cells through an in-vitro assay. The most active hydrolysate was fractionated using Sephadex G-15 and characterized by the molecular weight by LCMS/MS. The result showed that the optimum condition for hydrolysis was 1% (v/v) of enzyme concentration and 3 hours of incubation time with a %DH value of 3.01%. Based on the SDS-PAGE result, the hydrolysate had protein bands in a lower range (<25 kDa). That hydrolysate has cytotoxicity with an IC50 value of 1.87 mg/mL, and the molecular weight of its bioactive peptide is 7.70 kDa.

This action research study explored how peer assessment can help students and teachers evaluate algorithm problem-solving skills in mathematics. The study used a self- and peer-assessment activity in Moodle to assess 18 out of 40 Grade X students (10 boys and eight girls) from a school at Kathmandu Valley, Nepal. The students solved algorithm problems in arithmetic, algebra, statistics, and geometry. The study followed the action research methodology of planning, implementing, assessing, and discussing the interventions and outcomes. The results show that workshop activity can engage students in solving algorithm problems in mathematics. The study also discusses how cognitive and constructivist theories can explain some of this activity's unique aspects and potential uses. Moreover, the study highlights the benefits and challenges of self- and peer-assessment in mathematics for enhancing students' interest and abilities in the classroom. The study suggests students can develop analytical and evaluative skills using evaluation criteria to assess their peers' work. The study also implies that students are proactive, critical, and collaborative learners who can use self-and peer assessment to improve their mathematical abilities to solve algorithm problems in the classroom.

Objetivo: Investigar a provável presença de sarcopenia (SARC-F + CC) e sua associação com o estado nutricional e inflamatório em pacientes em pré-operatório de cirurgias do aparelho digestivo e coloproctológicas. Métodos: Estudo observacional e transversal, com pacientes em pré-operatório internados em um hospital universitário. Foram coletados dados sociodemográficos, clínicos e laboratoriais. Foram aferidas medidas antropométricas, força de preensão manual (FPM) e utilizados os instrumentos: SARC-F + CC, triagem de risco nutricional (NRS-2002) e Classificação do Estado Nutricional (AND-ASPEN). Foi aplicado o teste Qui-quadrado e utilizado o Programa STATA®, versão14.0. Resultados: Foram avaliados 85 pacientes, sendo 64,7% do sexo feminino, 29,4% idosos e 24,7% com provável sarcopenia (SARC-F + CC). Não houve associação estatística da provável existência de sarcopenia com os fatores sociodemográficos e categoria cirúrgica (oncológica ou não). A provável sarcopenia foi significativamente associada ao baixo peso e eutrofia (IMC) (p=0,001); FPM reduzida (p=0,003); risco nutricional (NRS-2002) (p=0,035); desnutrição grave associada à doença crônica/aguda (AND-ASPEN) (p<0,001); valores elevados de PCR (p=0,004); e hipoalbuminemia (p=0,001). Conclusão: A provável sarcopenia (SARC-F + CC) está associada significativamente à inflamação, ausência de excesso de peso (IMC) e pior estado nutricional (FPM; NRS-2002; AND-ASPEN) em pacientes em pré-operatório de cirurgias do aparelho digestivo e coloproctológicas.
