Family is a basic social unit of senior citizen. Relationship among family members considered as source of emotional comfort. Meanwhile, economic, political, and social changes during pandemic has an impact on the family, the support provided can be manifested among vulnerable groups such as the elderly. Prolonged stress due to isolation care of Covid-19 infection increase psychological distress by reducing family support. This study aimed to explore perceived family function among elderly patients after Covid-19 infection. A cross sectional study was conducted among 33 elder patients with history of Covid-19 infection in Saiful Anwar General Hospital, Indonesia. Perceived family functionality was evaluated using APGAR family score. Data was analyzed using descriptive analyses, independent T test, correlation and regression. Mean total APGAR score was 9.610.70 with joint pain had significant association with APGAR score (p 0.021) indicating full family support in elder person with symptoms. Gender female was associated with 'Resolve' (p 0.038) which might correlate with bigger role of elder female in Indonesian family. Length of stay was significantly associated with 'Partnership' (p 0.012) and 'Growth' (0.043) with inverse correlation. It showed how prolonged hospital stay affected family relationship especially in terms of communication. Perceived family supports remained high in elderly during Covid-19 isolation in Indonesia. Specific symptoms such as joint pain, even strengthen the family support for elder member of family. Prolonged stay in the hospital during Covid-19 infection, might become a communication barrier between elder person and the family which affect decision sharing and emotional expression.

Published: December 2022

Congenital adrenal hyperplasia (CAH) is the most common cause (60%) of Disorder of Sex Development (DSD), which causes three problems: symptoms and conditions arising due to adrenal endocrine disorders, long-term treatment, and quality of life due to genital ambiguity. An 18-year-old female patient was diagnosed with simple virilizing CAH and had genital ambiguity from birth. The patient was raised as a male. Overall, the examination results indicated a female. Physical examination before surgery showed virilization, such as external genital pigmentation, precocious pubic hair, and bilateral impalpable testis. The karyotype genetic examination confirmed female: 46, XX. Eventually, the patient decided as a female and underwent surgical management consisting of clitoroplasty, labioplasty, and vaginoplasty, followed by long-term corticosteroid therapy. Observations were made for three years after surgery to see the progress of the patient's condition. After undergoing glucocorticoid therapy and surgery, the patient had not experienced menstruation. Her breasts did not enlarge, and mustache and beard were still growing on her face. The patient was concerned about her condition, especially about the risk of infertility and inappropriate physical changes. The management of virilization in CAH with genital ambiguity should be seen from psychological and surgical perspectives. Understanding the disease, the goals of surgery, long-term treatment, and social adaptation help improve quality of life and reduce negative stigma.

Authors: Ekayoda Ovigueroye , Kadiri Helen Ejiro , Ohwokevwo Oghenenyore Andy
Published: December 2022

Background. Several toxicants present simultaneously in the environment have combined toxicological effects. In addition, various xenobiotics have distinct effects on oxidative stress biomarkers in animal cells and tissues.

The aim of this study was to analyze the effect of cadmium (Cd) and cyanide (CN) through the food chain on some antioxidant indices in the tissues (lungs, testes, heart, and brain) of male Wistar rats.

Materials and Methods. The study included sixty African catfish allocated to four groups, each comprising fifteen fish, treated with potassium cyanide (KCN) and cadmium chloride (CdCl2), held at a temperature of 25°C in a 100-litre fish tank aquarium with water contaminated with 0.4 mg of both cyanide and cadmium/100 ml of water. All the fish were later killed, dried, and used to prepare diet for experimental animals. Twenty male rats divided into four groups, each comprising five rats, were used for this study as well, and fed for 28 days as follows: Group A - control diet; Group B - cyanide-contaminated diet; Group C - cadmium-contaminated diet; Group D - diet contaminated with cyanide + cadmium. Subsequently, they were sacrificed. Biochemical analysis of the tissues excised from the rats was done.

Results. There was a significant (p < 0.05) increase in lipid peroxidation level and a significant decrease in superoxide dismutase, catalase and reduced glutathione activities in the lungs, testes, heart, and brain of rats fed a catfish diet containing both cyanide and cadmium as compared to controls. In addition, contaminated diet altered acetylcholinesterase activity in the brain, glutathione peroxidase activity, glutathione-S-transferase activity, and glutathione reductase activity in the tissues of experimental rats.

Conclusions. Cadmium and cyanide, via the food chain, induce oxidative stress in the lungs, testes, heart, and brain of rats.
App Design Features Important for Diabetes Self-management as Determined by the Self-Determination Theory on Motivation: Content Analysis of Survey Responses From Adults Requiring Insulin Therapy
Authors: Fu Helen N C , Wyman Jean F , Peden-McAlpine Cynthia J , Draucker Claire Burke , Schleyer Titus , Adam Terrence J
Published: December 2022

Background

Using a diabetes app can improve glycemic control; however, the use of diabetes apps is low, possibly due to design issues that affect patient motivation.

Objective

This study aimed to describes how adults with diabetes requiring insulin perceive diabetes apps based on 3 key psychological needs (competence, autonomy, and connectivity) described by the Self-Determination Theory (SDT) on motivation.

Methods

This was a qualitative analysis of data collected during a crossover randomized laboratory trial (N=92) testing 2 diabetes apps. Data sources included (1) observations during app testing and (2) survey responses on desired app features. Guided by the SDT, coding categories included app functions that could address psychological needs for motivation in self-management: competence, autonomy, and connectivity.

Results

Patients described design features that addressed needs for competence, autonomy, and connectivity. To promote competence, electronic data recording and analysis should help patients track and understand blood glucose (BG) results necessary for planning behavior changes. To promote autonomy, BG trend analysis should empower patients to set safe and practical personalized behavioral goals based on time and the day of the week. To promote connectivity, app email or messaging function could share data reports and communicate with others on self-management advice. Additional themes that emerged are the top general app designs to promote positive user experience: patient-friendly; automatic features of data upload; voice recognition to eliminate typing data; alert or reminder on self-management activities; and app interactivity of a sound, message, or emoji change in response to keeping or not keeping BG in the target range.

Conclusions

The application of the SDT was useful in identifying motivational app designs that address the psychological needs of competence, autonomy, and connectivity. User-centered design concepts, such as being patient-friendly, differ from the SDT because patients need a positive user experience (ie, a technology need). Patients want engaging diabetes apps that go beyond data input and output. Apps should be easy to use, provide personalized analysis reports, be interactive to affirm positive behaviors, facilitate data sharing, and support patient-clinician communication.

Published: December 2022

BACKGROUND

Chronic total occlusion (CTO) is an angiographic picture of total occlusion without blood flow which is estimated to have lasted at least three months. There is still controversy regarding the clinical outcome and quality of life between revascularization and medical therapy in CTO.

OBJECTIVE

This study attempted to provide an overview of the levels of MMP-9, sST2, and NT-pro BNP as remodeling, inflammatory, and atherosclerotic markers, as well as changes in the angina severity in patients with CTO who underwent percutaneous coronary intervention (PCI) compared to those without PCI.

METHODS

This is a Quasi-Experimental Design study with a pre-test and post-test approach to compare PCI's effect in CTO patients towards change in MMP-9, sST2, NT-pro BNP levels, and changes in the angina severity. Twenty subjects underwent PCI and 20 subjects with optimal medical therapy who were then assessed at baseline and eight weeks after intervention.

RESULTS

The results of this study showed that decreased MMP-9 (pre: 12.07±1.27 ng/ml vs. post: 9.91±5.19 ng/ml; p=0.049), sST2 (pre: 37.65±20.00 ng/ml vs. post: 29.74±15.17 ng/ml; p=0.026) and NT-pro-BNP (pre: 0.63±0.23 ng/ml vs. post: 0.24±0.10 ng/ml; p<0.001) levels were found after 8 weeks of PCI compared to those without such intervention. The levels of NT-pro BNP were lower in the PCI group (0.24±0.10 ng/mL) than in the non-PCI group (0.56±0.23 ng/ml; p<0.001). Moreover, there was an improvement of angina severity in PCI group than without PCI (p<0.039).

CONCLUSIONS

This study proves that PCI reduce MMP-9, NT-pro BNP, and sST2 levels and improve angina severity in CTO patients to a person without PCI.

Authors: Rizkilina Tri Multy , Rosyid Nur Rohman
Published: December 2022

Data traffic on a dense network is a threat to cybercrime and a high vulnerability for technology companies so that the challenges to prevent it will be more diverse. Adding a strengthening of the boundary wall or firewall and sorting data through packet filtering plus writing firewall rules to prevent malware and attacks from outside at the network device level is an alternative to protect the traffic you have. When heavy traffic makes data exchange uncontrollable, this research will create an automation design so that the sorting of incoming data packets through selection based on the specified rules runs in real-time so that the prevention of crime that enters the network is more swiftly handled. The system is running successfully by connecting the MQTT Collector as a subscriber that uses the python programming language to retrieve profiling data from the IP Profile database. The system was tested on a mikrotik router RB951Ui-2HnD which then the blocking track record will be stored in the Dynamic Firewall Data database in MongoDB. Also added a tool for controlling data in storage in the form of a program release. The results of the test show that data with an average base score above 20 is blocked and then stored in the block list in checking the collection in the database every 30 seconds. In addition, the data in the database will be checked every day within 30 days which will then be released and recorded in the release log in MongoDB.

In this study, the isolation of lactic acid bacteria was carried out from one hundred white cheese samples collected from different regions of Turkey. Subsequently, phenotypic and genotypic characterization of the isolates was performed. Biochemical characteristics of the isolates were determined by API 50CHL. Furthermore, the biotechnological enzyme production potential of the isolates was screened. Genomic fingerprint profiles of the test isolates were detected by using rep-PCR (BOX-PCR), which has been used successfully in the differentiation of microorganisms at the species, subspecies, and even strain levels. The results showed that a total of forty-one bacteria were isolated and seventeen of which are found to be different species. The isolates generally grew at 4-6 pH values, 0-8% NaCl and 30-40°C. Later, isolates thought to be different species were identified by 16S rRNA gene sequence analyses. According to 16S rRNA sequence results, MA56 showed a 96.41% similarity match to Lentilactobacillus buchneri, it is thought to be a new species. In addition, MA19, MA25, MA43, and MA47 were determined to have multi-enzyme production potential. MA43 has a plantaricin gene and it showed a high antagonistic effect on Escherichia coli O157:H7 ATCC 43888 and Pseudomonas aeruginosa ATCC 9027.

Published: December 2022

Paralelamente às intensas mudanças físicas, biológicas e comportamentais,  os adolescentes experimentam significativas transformações emocionais à medida que constroem novas relações interpessoais. As redes sociais se tornam grandes aliadas na manifestação de sentimentos, atitudes e decisões a respeito da vida particular que emergem nessa fase da vida. A preocupação com a abordagem do tema sexualidade nas escolas é recorrente, visto que a instituição escolar visa o desenvolvimento do indivíduo como um todo. O presente trabalho propõe uma metodologia que tem o intuito de auxiliar os estudantes, na compreensão do funcionamento do aparelho genital humano a partir de estudos de casos de adolescentes fictícios que relatam situações vividas por eles ou pensamentos em relação aos conceitos: ciclo reprodutivo, puberdade e idade reprodutiva. Dentro da proposta, os estudos de caso são apresentados aos estudantes na forma de relatos ou afirmações, simulando postagens em redes sociais. Infere-se a necessidade de permitir que os estudantes conheçam a linguagem científica, enxergando essa área da Ciência como uma atividade relacionada ao seu bem estar, à sua saúde, e que tem implicações diretas para  sociedade. Como forma de sustentar o Ensino por Investigação, a proposta apresenta alguns elementos para que o estudante raciocine cientificamente, adotando uma postura investigativa para a resolução dos casos.

VEIO PARA FICAR? O USO DAS MÍDIAS SOCIAIS POR CENTROS E MUSEUS DE CIÊNCIAS BRASILEIROS DIANTE DA PANDEMIA DE COVID-19
Authors: Ribeiro Alice , Massarani Luisa , Falcão Douglas
Published: December 2022

Neste artigo, analisamos o uso das mídias sociais por centros e museus de ciências brasileiros no contexto da pandemia de Covid-19, marcado pelo fechamento das instituições para o acesso do público e pela migração das atividades museais para o formato remoto. Por meio de questionário aplicado a gestores(as) de 89 centros e museus de ciências espalhados por todo o Brasil, nosso estudo traz evidências que apontam para um redirecionamento no modo como as mídias sociais são usadas por essas instituições, passando da divulgação de eventos e outras informações de funcionamento, para a educação e divulgação científica. Entretanto, essa mudança ocorreu sem a ampliação de recursos humanos e financeiros, bem como sem formação das equipes para a realização de ações digitais e/ou online. Os participantes da pesquisa acreditam que a atuação online permitiu a ampliação e diversificação geográfica do público e são otimistas sobre a continuidade dessa atuação no pós-pandemia, mas receiam que a falta de recursos possa ser prejudicial à conciliação de ações presenciais e remotas.

Este estudo teve como principal objetivo avaliar as percepções de discentes da Educação Básica (ensino médio) acerca do retorno às atividades acadêmicas presenciais, destacando, sobretudo, a autoavaliação da aprendizagem, as potencialidades, as fragilidades e as dificuldades envolvidas no processo de retorno pós-pandemia. Para alcançar o referido objetivo, foi realizada uma pesquisa de campo, com coleta de dados online, utilizando o Google Forms, junto a 155 discentes do ensino médio de oito instituições públicas de ensino diferentes, localizadas nas regiões Norte e Nordeste do Brasil. Em termos sociodemográficos gerais, os participantes possuem idades entre 15 e 21 anos. Pelo menos 55,5% estão cursando o 3º ano do ensino médio atualmente e 66,9% afirmam morar na zona urbana. Os resultados demonstraram que a grande maioria dos discentes vivenciaram o ensino remoto, e uma significativa parcela avalia as atividades acadêmicas remotas como regulares. Os demais resultados apontaram dificuldades no processo de aprendizagem durante o período remoto e uma ausência de preparação para o retorno presencial. Destaca-se, ainda, o desejo dos alunos para o retorno presencial e uma avaliação mais positiva da própria aprendizagem em atividades presenciais. A partir de tais resultados, emergem contribuições para a prática educacional e para a literatura, além de ser sinalizada uma possível agenda de pesquisas futuras: levantamentos semelhantes acerca de percepções de discentes, do ensino médio, sobre potencialidades e desafios do retorno presencial em outras regiões do Brasil e estudos comparativos entre diferentes séries do último ciclo da Educação Básica. PALAVRAS-CHAVE: retorno presencial; educação básica; ensino médio.

O artigo relata e discute uma experiência educativa dialógica com base em uma disciplina eletiva da graduação em Ciências Biológicas da Universidade Federal do Rio de Janeiro, oferecida durante a pandemia do coronavírus (Covid-19). Dialoga com a perspectiva de bell hooks e de Paulo Freire no campo educacional e experimenta a “cartografia do imaginário”, elaborada por Michèle Sato. A educação ambiental desde el Sur serviu de substrato para as reflexões sobre a formação docente e de cientistas no campo das Ciências Biológicas. Propõe processos dialógicos em rede e de maneira digital. A partir de temas socioambientais estabelece a troca de olhares pela produção de fotografias e vídeos e pelas narrativas escritas e orais das experiências vividas no isolamento social. Conclui que no período da experiência deste artigo, a produção audiovisual compartilhada constituiu um processo fértil para criação de uma proposta didática dialógica durante o ensino remoto, principalmente quando esteve contextualizada às realidades socioambientais dos estudantes. Os princípios da educação popular, como a dialogicidade, a horizontalidade e a contextualização às realidades locais podem se fazer presentes mesmo em atividades remotas, o que pode facilitar a construção de processos pedagógicos significativos. PALAVRAS-CHAVE: educação ambiental; educação em ciências; formação docente; audiovisual; pandemia

Cryptocurrency and money laundering: A literature review
Authors: Guidara Achraf
Published: December 2022

According to previous research, cryptocurrency is a driver of money laundering and is associated with several risks (Fletcher, Larkin, & Corbet, 2021; Teichmann & Falker, 2020; Tsuchiya & Hiramoto, 2021). As a result, the purpose of this paper is to concentrate on empirical research in the accounting and finance fields that deal with the impact of cryptocurrencies on the phenomenon of money laundering. To identify relevant literature, we use the following keywords including “cryptocurrency or digital money” and “bitcoin and money laundering”. We identify 28 research papers published between 2011 and 2021. The findings of the studies that were reviewed emphasized the importance of developing a legal framework for digital currencies. Furthermore, it was revealed that all stakeholders play an important role in lowering the risk of money laundering and illicit activities. The findings highlight the critical role that banks, regulators, and all stakeholders play in reducing money laundering risks. These findings may have policy implications for governments aiming to improve cryptocurrency laws and regulations by enforcing financial security standards and laws and monitoring individuals’ and firms’ compliance with them. The review identifies some of the literature’s limitations and suggests future research directions
A Multiplicative calculus approach to solve applied nonlinear models
Authors: Bhalla Sonia , Behl Ramandeep
Published: December 2022

Problems like population growth, continuous stirred tank reactor (CSTR)
and ideal gas are studied from the last four decades in the field
medicine science, Engineering and applied science, respectively. One of
the main motivation was to understand the pattern of such issues and how
to fix them. With the help of applied Mathematics, such problems can be
converted or modeled by nonlinear expressions with similar properties
and the required solution can be obtained by iterative techniques. In
this manuscript, we proposed a new iterative scheme for multiple roots
(without prior knowledge of multiplicity m) by adopting
multiplicative calculus rather than the standard calculus. The base of
our scheme is on the well-known Schröder method and we retain the same
second-order of convergence. In addition, we extend the order of
convergence from second to fourth by constructing a two-step joint
Schröder scheme with hybrid approach of ordinary and multiplicative
calculus. Some numerical examples are tested to find the roots of
nonlinear equations and results are found to be competent as compared to
ordinary derivative methods. Finally, the convergence of schemes is also
analyzed by basin of attractions that also support the theoretical
aspects.
Aggregate Financial Misreporting and the Predictability of U.S. Recessions and GDP Growth
Authors: Beneish Messod D. , Farber David B. , Glendening Matthew , Shaw Kenneth W.
Published: December 2022

This study examines the incremental predictive power of aggregate measures of financial misreporting for recession and real gross domestic product (GDP) growth. We draw on prior research suggesting that misreporting has real economic effects because it represents misinformation on which firms base their investment, hiring, and production decisions. We find that aggregate M-Score incrementally predicts recessions at forecast horizons of five to eight quarters ahead. We also find that aggregate M-Score is significantly associated with lower future growth in real GDP, real investment, consumption, and industrial production. Additionally, our result that aggregate M-Score predicts lower real investment one to four quarters ahead partially accounts for why misreporting predicts recessions five to eight quarters ahead. Our findings are weaker when we use aggregate F-Score as a proxy for misreporting. Overall, this study provides novel evidence that aggregate misreporting measures can aid forecasters and regulators in predicting recessions and real GDP growth.

BACKGROUND

Optimal length of biliopancreatic (BP) and Roux limb in Roux-en-Y gastric bypass (RYGB) for improved glycemic control are not known.

PURPOSE

To investigate how the lengths of the BP and Roux limbs in RYGB differentially affect postoperative glycemic outcomes in patients with type 2 diabetes.

DATA SOURCES

We conducted a systematic literature search using the PubMed, Embase, and the Cochrane Library databases.

STUDY SELECTION

We included studies that reported glycemic outcomes after RYGB and lengths of the BP and Roux limbs.

DATA EXTRACTION

A total of 28 articles were included for data extraction. Glycemic outcomes after RYGB were assessed on the basis of two definitions: remission and improvement.

DATA SYNTHESIS

We categorized the included studies into four groups according to the BP and Roux limb lengths. The type 2 diabetes remission/improvement rates were as follows: long BP–long Roux group 0.80 (95% CI 0.70–0.90)/0.81 (0.73–0.89), long BP–short Roux group 0.76 (0.66–0.87)/0.82 (0.75–0.89), short BP–long Roux group 0.57 (0.36–0.78)/0.64 (0.53–0.75), and short BP–short Roux group 0.62 (0.43–0.80)/0.53 (0.45–0.61). Meta-regression analysis also showed that a longer BP limb resulted in higher postoperative type 2 diabetes remission and improvement rates, whereas a longer Roux limb did not. There was no significant difference or heterogeneity in baseline characteristics, including diabetes-related variables, among the four groups.

LIMITATIONS

Not all included studies were randomized controlled trials.

CONCLUSIONS

Longer BP limb length led to higher rates of type 2 diabetes remission and improvement by 1 year after RYGB in comparisons with the longer Roux limb length.

BACKGROUND: Optimal length of biliopancreatic (BP) and Roux limb in Roux-en-Y gastric bypass (RYGB) for improved glycemic control are not known.

PURPOSE: To investigate how the lengths of the BP and Roux limbs in RYGB differentially affect postoperative glycemic outcomes in patients with type 2 diabetes.

DATA SOURCES: Systematic literature search using the PubMed, EMBASE, and the Cochrane Library databases.

STUDY SELECTION: Studies that reported glycemic outcomes after RYGB and lengths of the BP and Roux limbs.

DATA EXTRACTION: Twenty-eight articles were included for data extraction. Glycemic outcomes after RYGB were assessed using two definitions: remission and improvement.

DATA SYNTHESIS:  We categorized the included studies into four groups according to the BP and Roux limb lengths. The type 2 diabetes remission/improvement rates (95% confidence interval [CI]) were as follows: long BP‒long Roux group, 0.80 (0.70‒0.90)/0.81 (0.73‒0.89); long BP‒short Roux group, 0.76 (0.66‒0.87)/0.82 (0.75–0.89); short BP‒long Roux group 0.57 (0.36‒0.78)/0.64 (0.53‒0.75); short BP‒short Roux group, 0.62 (0.43‒0.80)/0.53 (0.45‒0.61). Meta-regression analysis also showed that a longer BP limb resulted in higher postoperative type 2 diabetes remission and improvement rates, whereas a longer Roux limb did not. There was no significant difference or heterogeneity in baseline characteristics, including diabetes-related variables, among the four groups.

LIMITATIONS: Not all included studies were randomized controlled trials.

CONCLUSIONS: Longer BP limb length led to higher rates of type 2 diabetes remission and improvement by 1 year after RYGB than the longer Roux limb length.

Objective

To quantify associations between educational outcomes with type 1 diabetes status and glycaemic management (Hba1c).

Research Design and Methods

A record linkage study of schools and higher (college) education datasets linked to national diabetes audits. The population includes all Welsh children attending school between 2009 and 2016, yielding eight academic cohorts with attainment data, including 263,426 children without diabetes and 1,212 children diagnosed with type 1 diabetes. Outcomes include standardised student attainment aged 16 years, higher education participation aged 18 years, and school absences aged 6 to 16 years.

Results

Comparison between children with type 1 diabetes and children without diabetes showed no strong evidence of associations for student attainment (+0·001 SD, CI -0·047 to 0·049, p<0·96 n=1,212 vs 263,426) or higher education entry rates (OR=1·067, CI=0·919 to 1·239, p<0·39 n=965 vs 217,191), despite nine more sessions of absence from school annually (p<0·0001). However, attainment in children in the most optimal HbA1c quintile was substantially better than children without diabetes (+0·267 SD, CI 0·160 to 0·374, p<0·001) while being worse than children without diabetes in the least optimal quintile (-0·395 SD, CI -0·504 to -0·287, p<0·001). Attainment did not differ by duration of ‘exposure’ to diabetes based on age at diagnosis.

Conclusions

Despite greater school absences, being diagnosed with diabetes is not associated with educational attainment or entry into higher education, although attainment does vary by HbA1c levels, which may be explained in part (or wholly) by unobserved shared personal, family, or socioeconomic characteristics associated with both success in education and effective glycaemic self-management.

Abstract. The COVID-19 pandemic has impacted on the educational aspects of various levels of education, and several countries have shut schools nationwide affecting two-third of students worldwide. This change challenges the students who usually involved in face-to-face learning to switch to distance learning (online), and thus it influences their life as students and individuals. This study aims to determine the effect of psychological capital, academic buoyancy, and academic major satisfaction on academic adjustment of senior high school students during the COVID-19 pandemic. The subjects in this study were 145 students, taken by random sampling technique from the total population. The method used in this study was quantitative methods by using Structural Equation Modeling (SEM) analysis. Data collection employed was four scales: the psychological capital scale, academic buoyancy, academic major satisfaction, and the academic adjustment. The results of this study indicate that the R-Square value of the endogenous latent variable is 0.463, which means that the psychological capital, academic buoyancy, and academic major satisfaction variables have an influence on the academic adjustment variable of 46.3%. Thus, the hypothesis proposed in this study is accepted. Therefore, there is a significant positive effect of psychological capital, academic buoyancy, and academic major satisfaction on the academic adjustment of senior high school students during the COVID-19 pandemic. Keywords: psychological capital; academic buoyancy; academic major satisfaction; academic adjustment; senior high school students.

Wide spread of RC structures in construction projects indicates the necessity of their service life prolongation. Perspective possibility to increase strength of RC structures is use of external composite tapes. The article presents theoretical research on the effectiveness of strengthening of RC bended elements with the use of composite tapes. Work also includes comparative analysis on the basis of calculations, according to normative regulations. With the use of developed algorithm parameters of stress-strain state and deformability of RC beams, strengthened with composite tapes were obtained. Study identified, that the most critical parameter was the steel bars` strain and yield point. Interesting finding of the study is the no-linearity of the strength growth of the studied elements with the increase of additional reinforcement amount. Consistent literature review was conducted, which identified the necessity to take into account different external factors and failure mode.

Reinforced concrete pipes are exposed to environmental influences during the entire period of their operation. As a result, defects and damage appear and reduce durability and bearing capacity. In this regard, there is a need to repair and strengthen them. In order to assess the effectiveness of strengthening reinforced concrete pipes, it is necessary to get data about deformations that appeared as a result of the loads on the reinforced concrete pipe. The method for conducting experimental studies of the deformed state of reinforced concrete pipes has been developed, and the main devices and means necessary for conducting experimental research in laboratory conditions have been selected. The obtained data of deformations appearance can be used to compare the effectiveness of various methods of strengthening reinforced concrete pipes and their improvement as well as to monitor technical condition and to predict the formation of defects.

Published: December 2022

Como se sabe, as aves possuem grande importância para a dispersão de sementes de várias espécies de plantas nativas, auxiliando na manutenção estrutural e preservação das florestas. Ilex paraguaiensis St. Hill., conhecida como erva-mate, possui grande importância econômica para o sul do Brasil, sendo utilizada para diferentes formas de consumo. O presente trabalho objetivou comparar as taxas de germinação de sementes coletadas manualmente e sementes que passaram pelo trato digestório de aves. As coletas ocorreram no interior do município de Bituruna, Paraná, utilizando plantas nativas. As coletas foram realizadas com auxílio de telas sombrites, sendo coletados tanto os frutos que caíram naturalmente quanto aqueles que foram defecados por aves. As sementes passaram por um período de três meses de estratificação, posteriormente semeadas no solo. A porcentagem de germinação (n=200 para cada tipo de dispersão) foi obtida através da contagem do número de plântulas emergidas para obtenção das taxas de germinação de ambas as coletas. Em adição, foram medidas a altura e contado o número de folhas. Foram obtidos valores de 6,5% de germinação para as sementes coletadas manualmente e 42,5 % para àquelas oriundas do processo de predação, sendo esta diferença significativa estatisticamente. Para o tamanho da planta e número de folhas não foram observadas diferenças significativas. Os resultados demonstraram que a passagem pelo trato digestório dos pássaros promoveu um aumento na porcentagem de germinação sugerindo um efeito positivo, possivelmente na quebra de dormência das sementes de erva mate.
