Authors: Grosseli Eduarda , Weirich Ribeiro Inaua , Vier Munhoz Angélica 
Published: May 2023

O presente artigo deriva de um projeto de pesquisa vinculado ao Grupo de Pesquisa Currículo, Espaço, Movimento, da Universidade do Vale do Taquari - Univates. Esta investigação foi realizada por uma bolsista de iniciação científica, em conjunto com uma bolsista de doutorado do Programa de Pós-graduação em Ensino da mesma Universidade, orientadas pela professora coordenadora do Grupo. O objetivo da pesquisa foi arquivar e arquivizar as teses de doutorado da Área de Conhecimento em Ensino (publicadas no período de 2013 a 2020) que operam com a noção de aula na formação inicial de professores no Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior. Para tanto, utilizou-se, como referencial teórico-metodológico, a noção de arquivo de Michel Foucault. Como procedimentos arquivísticos, operou-se com os dispositivos de arquivamento e arquivização, a partir de Aquino e Val. Dispondo do arquivo e dos demais procedimentos citados, foi possível observar os enunciados correspondentes às noções em destaque – aula e formação inicial de professores. A investigação não tem a intenção de exibir uma definição das noções; todavia, evidenciou o modo como elas emergiram nesse arquivo. Dessa forma, verifica-se, como resultado, uma quase-invisibilidade das noções de “aula” e de “formação inicial de professores” na produção de teses de doutorado da Área de Conhecimento em Ensino no Brasil (período de 2013 a 2020).
Visual Quality Improvement of Watermarked Image Based on Singular Value Decomposition Using Walsh Hadamard Transform

Published: May 2023

Abstract
Embedding the watermark is still a challenge in image watermarking. The watermark should not reduce the visual quality of the image being watermarked and hard to distinguish from its original. Embedding a watermark of a small size might be a good solution. However, the watermark might be easy to lose if there is any tampering with the watermarked image. This research proposes to increase the visual quality of the watermarked image using the Walsh Hadamard transform, which is applied to the singular value decomposition-based image watermarking. Technically, the watermark image is converted into a low bit-rate signal before being embedded in the host image. Using various watermark sizes, experimental results show that the proposed method could produce a good imperceptibility with 47.10 dB on average and also gives robustness close to the original watermark with a normalized correlation close to 1 on average. The proposed method can also recognize the original watermark from the tampered watermarked image at different levels of robustness.

Published: May 2023

Abstract
The current study employs the finite element method to compare stress concentration pertaining to a graphite / epoxy rectangular laminated composite plate that possess holes in different shapes. The hole enables redistributing in-plane stresses, impacts the stress concentration factor (SCF), and focuses maximum stress near the hole. The ANSYS program has been designed to be employed for parametric studies pertaining to plates that have a hole under uniaxial in-plane load. Analysis was done for angle-ply, four-layered symmetrically laminated rectangular plates that include different stacking sequences ± θ.

Published: May 2023

Abstract
Anchovy is one of the economically important fish in the western part of the northern coast of Central Java. The production of anchovies extends along the coast from Brebes Regency to Batang Regency. Therefore, this study aims to determine the diversity of anchovies on the northern coast of Central Java (Brebes, Tegal, Pemalang, Batang, and Kendal), using a molecular approach. This study was conducted from April to September 2019 in the Laboratory of Tropical Marine Biotechnology, Faculty of Fisheries and Marine Science, Universitas Diponegoro. The descriptive exploratory method was applied in this study with a random sampling technique, while the cytochrome oxidase I (COI) gene was used for molecular identification. An anchovy sample molecularly identified from each region was found by sampling, including BB 3, PML 2, BTG 1, BTG 2, BTG 4, TGL 2, TGL 4, KDL 1, and KDL 4. The base-pair length of 10 anchovy samples from the COI gene amplification result was 600-700 bp. The sequencing and alignment results of the BLAST analysis showed that the ten anchovy samples were included in the type of Encrasicholina heteroloba, Stolephorus commersoni, Stolephorus waitei and Atherinomorus sp., which ranged from 98 to 99% similarity in location. Therefore, it is concluded that there were at least four different species of anchovy on the northern coast of Java. However, further research is suggested to determine the genetic variation of each species for better fisheries management.

Authors: Fraenkel Emil , Lazurova Ivica 
Published: May 2023

Abstract

Objective. The aim of the present study was to assess insulin-like growth factor 1 (IGF-1) and IGF-binding protein 3 (IGFBP3) as markers of insulin resistance in patients with prediabetes and type 2 diabetes mellitus (TDM2).

Patients and Methods. This observational clinical study included 76 obese/overweight patients at the age of 45–75 years with T2DM on oral diabetic medication and ultrasonographically or by a computerized tomography (CT) diagnosed liver steatosis. Correlation analysis was performed between plasma levels of insulin, C-peptide, IGF-1, IGFBP3 and HOMA indexes on the one hand and between plasma levels of ALT, AST, triglyceride, cholesterol, and HDL cholesterol and body mass index (BMI) of patients on the other hand. In case of significant partial correlation coefficients, a multiple linear regression model with IGF-1 and IGFBP3 used as outcome variables adjusted for age and sex groups was calculated. According to these regression models, ROC curves were prepared with HOMA index=3 used as a classificator of insulin resistance.

Results. Significant correlation was found between C-peptide and IGF-1 (r=0.24, p≤0.05), C-peptide and IGFBP3 (r=0.24, p≤0.05), IGFBP3 and cholesterol (r=0.22, p≤0.05) IGFBP3 and ALT (r=0.19, p≤0.05), HOMA index and triglycerides (r=0.22, p≤0.05), and HOMA index and ALT (r=0.23, p≤0.05). Significant correlation adjusted for age and gender was found between C-peptide and IGF-1 plasma levels (R2=0.20, p<0.05) with AUROC 0.685 (p≤0.01) and C-peptide and IGFBP3 plasma levels (R2=0.28, p<0.05) with AUROC 0.684 (p≤0.01). Significant correlation adjusted for age and gender was found between triglyceride and IGFBP3 plasma levels (R2=0.28, p<0.05) with AUROC 0.616 (p≤0.01). After the distribution of patients according to their IGFBP3 levels, we found a difference between the 1st and the 4th quartiles in terms of triglyceride levels.

Conclusion. Our results demonstrate a fundamental role of IGF-1 and IGFBP3 in the patho-physiology of hepatic insulin resistance and suggest them as indirect indicators of the hepatic insulin resistance.

Abstract
The 3D model of a building was built to analyze the scene of a fire with reference to the real situation. The process of evolution of a fire was simulated with FDS. The evolution time of the fire, the degree of danger, the temperature as well as the visibility was analyzed. Architectural solutions that could be considered for the prevention and evolution of fire in the presented situations were also analyzed. The results of the simulations in the proposed scenarios showed that solutions could be found to prevent the spread of fire. The results of the study provide a real base for improving the evacuation conditions and limiting the damage caused by fire in single-family buildings.
Influence of biochar on improving hydrological and nutrient status of two decomposed soils for yield of medicinal plant - Pinellia ternata
Authors: Ng Charles Wang Wai , Touyon Lisa , Bordoloi Sanandam 
Published: May 2023

Abstract
The root tuber of Pinellia ternata has been used as a traditional therapeutic herbal medicine. It is reported to impart beneficial attributes in recovering COVID-19 patients. To meet an increasing demand of P. ternata, this study is intended to investigate the effects of biochar on the soil hydrological and agronomic properties of two decomposed soils (i.e., completely decomposed granite (CDG) and lateritic soil) for the growth of P. ternata. The plant was grown in instrumented pots with different biochar application rate (0%, 3% and 5%) for a period of three months. Peanut shell biochar inclusion in both soils resulted in reduction of soil hydraulic conductivity and increase in soil water retention capacity. These alterations in hydrological properties were attributed to measured change in total porosity, biochar intra pore and hydrophilic functional groups. The macro-nutrient (i.e., N, P, K, Ca, and Mg) concentration of both soils increased substantially, while the pH and cation exchange capacity levels in the amended soils were altered to facilitate optimum growth of P. ternata. The tuber biomass in biochar amended CDG at all amendment rate increases by up to 70%. In case of lateritic soil, the tuber biomass increased by 23% at only 5% biochar application rate. All treatments satisfied the minimum succinic acid concentration required as per pharmacopoeia standard index. The lower tuber biomass exhibits a higher succinic acid concentration regardless of the soil type used to grow P. ternata. The biochar improved the yield and quality of P. ternata in both soils.

Published: May 2023

Abstract
The crisis caused by the Covid pandemic is certainly the major disruptive event of this first quarter century, the Russian-Ukrainian military crisis also having the potential (in terms of the global dysfunctions generated) to fit into this typology. Beyond the clear negative effects (social, human, economic, etc.) of the Covid pandemic, however, we must also consider the possible challenges it may pose. The research question of the present article is situated in this thematic register, on a niche topic, urban resilience, re-evaluated, following the materialization of this pandemic context, both in academic research and in terms of contemporary management practice. It is intended, in conjunction with a bibliometric analysis, to highlight possible directions of action within the triple and quadruple helix models for strengthening urban resilience based on the lessons learned from this crisis, directions that are considered useful to a wide range of stakeholders in academia, industry and government. While there is sufficient concern directed towards determining resilience indices, the main thesis considered for this article is that there is a need for synergistic stakeholder action, integrating such elaborations into the proactive framework of a robust yet scalable urban resilience profile in relation to a wide range of events across the urban community security threat spectrum, as was the case with Covid 19.

Abstract
The development of e-commerce requires the strengthening of this component of the pharmaceutical business while providing the population with medicines. Improving the operation of pharmacy websites is an important task with a significant marketing effect. The purpose of the study is to identify errors on pharmacy websites that worsen their usability and communicative qualities when interacting with visitors, to offer an approach based on a joint assessment of consumer perception and technical parameters, and to carry out calculations for a comparative analysis of such sites functional and technical components using a multi-criteria approach. The objectives of the study were to analyze the Internet trade in medicines, to determine the criteria for comparison of pharmacy sites, to develop a model for website evaluation, and to analyze the results of site quality estimation. Multicriteria comparison with different importance of criteria was used as the methodology to evaluate the usability of sites for online buyers of pharmaceutical products. As result two main components of the quality of pharmacy sites are identified: user interface and technical characteristics. The parameters of site evaluation for these components are described, and evaluation is performed. A computer model in Excel has been developed. The proposed approach and the program allow for assessing pharmacy sites’ quality, comparing their marketing opportunities, directions to improve functionality, pharmaceutical services, and business position of pharmacies. The described steps for website estimations can be used not only in pharmaceutical services but for wide kinds of sites for e-commerce.

Abstract
Company valuation stands as the most controversial topic in the field of financial management. The study investigates the extent to which stock prices of the companies listed on Czech, Polish, Hungarian, and Slovak equity markets deviate from their estimated intrinsic value. DCF model was employed using Monte Carlo simulations with 500, 1000, and 10000 trials to generate estimated intrinsic value and compare them to market prices. The results of the study show that the Bratislava Stock Exchange (SAX) on average holds the lowest gap between intrinsic value per share and market prices with only 82% deviation, followed by PSE with 116% deviation, WIG20 with 207% deviation, and BUX with 246%. SAX appears with the best performance from 2009 to 2019, where the shares on average were traded with only 82% deviation from their estimated equilibrium price (intrinsic value). Findings regarding the differences between book value per share and stock prices are different, where SAX leads with 71% deviation, WIG20 with 181%, PSE with 188%, and BUX with 545%. Outcomes of the work are of interest to financial investors that seek to diversify their portfolios on the equity stocks. The study offers a new conceptual framework for testing the market efficiency of equity exchanges through company valuations techniques. From the policy perspective, institutions in charge get inform on the measures to be taken that would improve efficiency and strengthen the importance of the Visegrad equity markets.

Background. Assessing the probability of an adverse outcome of severe infections and sepsis in children in order to timely correct treatment is one of the most acute problems of resuscitation and intensive care. The ojective was to identify predictors of the adverse outcome of severe infections and sepsis in children upon admission to ICU. Materials and methods. Design – a retrospective cohort multicenter uncontrolled study. 180 children with a severe course of infectious diseases and sepsis were examined. The mean age of the patients was 1.3 (0.5–4.1) years, boys were 94 (52.2 %) patients and girls were 86 (47.7 %) patients. Signs of shock at admission were detected in 100 (55.6 %) children. The PEMOD score on the first day of treatment in ICU was 5.0 (40–8.0) points. The duration of treatment in ICU was 8.6 (1–83) days. Depending on the outcome of the disease, all patients were divided into two groups: groupI – «recovery», group II – «death». Results. Significant differences depending on the outcome of the disease were characteristic of clinical and laboratory signs such as mean bloodpressure, base deficiency, PEMOD score, concentration of total protein, albumin and lactate in the blood. Mean blood pressure below 60 mmHg., base deficiency > [–8.4] mmol/L, plasma lactate greater than 3.3 mmol/L, serum albumin less than 30 g/L and PEMOD > 7 on ICU admission indicate a high probability of death. The magnitude of the base deficiency has the maximum sensitivity (87.5 %) and specificity (61.3 %) to predict outcome on ICU admission. Conclusion. The severity of the condition of children with a severe course of infectious diseases and sepsis upon admission to ICU is due to the phenomena of systemic hypoperfusion, hypoxia and metabolic disorders against the background of hypoalbuminemia.

The objective – to evaluate the dynamics and prognostic value of inflammatory markers and other laboratory parameters in the blood of patientswith COVID-19 and to assess the severity of the course and mortality in this disease. Materials and Methods. The clinical and laboratory data of 819 patients with COVID-19 treated in a hospital were retrospectively analyzed. In 700 (85.5 %) patients, the disease occurred in a moderate form, these patients were recovered. Patients with severe course (n = 119) were treated in the intensive care unit, of which 47 (39.5 %) patients had a favorable outcome and 72 (60.5 %) patients died. All patients underwent clinical, biochemical (including IL-6) and coagulological studies at admission and in dynamics. The concentration of IL-1ß, IL-8, IL-10, tumor necrosis factor TNF-α were additionally measured in patients with severe COVID-19. Results. Initially, patients with severe disease, compared with moderate, had higher levels of C-reactive protein (p < 0.001), LDH (p = 0,007), D-dimers (p = 0.028), fibrinogen (p = 0.014), the number of white blood cells (p = 0.018), as well as lower levels of albumin (p < 0.001). In the group of patients with fatal outcome, higher levels of LDH (p = 0.008), creatinine (p = 0.009), urea (p < 0.001), troponin (p = 0.024), D-dimers (p = 0.002), fibrinogen (p = 0.009), the relative content of immature leukocytes (p = 0.004), neutrophil to lymphocyte ratio (p = 0.022) were found than in survivors. On the 7th day of hospitalization, an acute increase in ferritin, urea, D-dimers, LDH, interleukins was noted in the group of deceased patients. Using the observer’s operating curves method, predictors of an unfavorable outcome in COVID-19 were determined: IL-10 above 9.46 pg/ml (area under the ROC curve AUC = 0.902), urea above 6.6 mmol/L (AUC = 0.815), TNF-α above 12.6 pg/ml (AUC = 0.799), C-reactive protein above 59.6 mg/L (AUC = 0.714), LDH above 348 U/L (AUC = 0.702), neutrophil to lymphocyte ratio above 4.94 (AUC = 0.700), IL-6 above 62.2 pg/ml (AUC = 0.686), ferritin above 772 μg/L (AUC = 0.654). Conclusions. Baseline levels of LDH, D-dimers, and fibrinogen have a discriminatory ability to determine both the severity and the outcome of COVID-19. The severity of the inflammatory response upon admission correlates with the severity of the disease, but has no prognostic value. At the time of admission, patients with an unfavorable outcome already have initial manifestations of organ dysfunction (assessed by creatinine, urea, and troponin levels). On the 7th day of hospitalization, the relationship of values and the outcome appears in ferritin and interleukin 6. The presence of a strong correlation between the levels of interleukins IL-6, IL-8, IL-10, TNF-α makes it possible to measure any of them.

evaluate the frequency of mistakes made without it and with its use. Materials and methods. The study included 32 residents of the first year of study in the specialty «Anesthesiology and Resuscitation», who had previously held theoretical lectures on the topic: «Organization of the workplace of an anesthesiologist». In the simulation center, the subjects were asked to prepare the anesthesiologist’s workplace. The trainees were divided into two groups. The1st group – performing the task without prior acquaintance with the checklist and the 2nd group – acquaintance with the checklist. The assessment was carried out by two teachers independently of each other using a checklist modified for objective assessment of the subjects. Results. In the 1st group, 8 (50 %) students coped with the task, in the 2nd group, in 15 cases (94 %), the task was successfully completed. Checking the availability of funds for tracheal intubation was successfully completed by trainees in both groups. At the same time, points were identified: a leak test and checking the correct functioning of the anesthetic-respiratory apparatus, which the subjects could not cope with, which required more detailed consideration, both in theoretical and practical classes of these issues. Conclusion. The use of the checklist: «Organization of the workplace of an anesthesiologist» allows to increase the effectiveness of training of residents and reduce the number of mistakes made.
