Intraoperative pathology consultation is often required for guiding immediate surgical decisions so as to limit the extent of surgery. Accurate intraoperative diagnosis is crucial. The present study evaluates the accuracy of imprint cytology and frozen section in intraoperative consultation for tumor and tumor margins. A total of 157 tissue specimens for type of lesion, tumor margins and lymphnode metastasis were included. Imprint was taken by holding the tissue bit with forceps and touching it onto a clean glass slide without undue pressure or lateral movements. They were stained with Papanicolaou, May-Grunwald Giemsa and Hematoxylin and Eosin [H&E] stains. The tissue bits taken were then embedded and frozen. Section cutting was done using cryostat and were stained using rapid Haematoxylin and Eosin stain, and examined under a light microscope. Later, the tissue was fixed in 10% neutral buffered formalin for routine histopathological processing then stained with H&E stain. Based on the histological diagnosis, the accuracy of intraoperative imprint cytology and frozen section were evaluated. A total of 157 tissue specimens were received during the study period, which were classified into specimens for type of tumor [145 specimens], tumor margins [54 specimens] and lymph node metastasis [7 specimens] for analysis. The overall diagnostic accuracy of imprint cytology in detection of type of tumor was 97.9% and that of frozen section was 98.6%. It can be concluded that imprint cytology typically provides the accurate diagnosis without the need for a sophisticated machine such as cryostat which is required for frozen section analysis.

Published: January 2023

In recent times, image synthesis has attracted significant attention of people for both positive and negative reasons. Images can be easily synthesized using various techniques. This paper surveys various techniques for image synthesis as well as its detection in a unique structured manner, to enable a perspective on this iterative phenomenon. The paper describes both advantages and limitations starting from simple fake image detection to AI synthesized image detection approaches that are available in the literature. Generative Adversarial Network (GAN) is the trending algorithm for artificial image synthesis, because the faces generated by GAN are highly realistic. As discriminators are already present in the GAN’s structure, any attempt to create a distinguisher that detects fake images synthesized by GAN, needs to structure itself to detect all existing patterns of fake image synthesis including that of GAN.

The increasing demand for plant-based medicines makes plant research attractive to find natural alternatives that can replace synthetic products or at least reduce their use. Saponins are a group of natural phytochemical compounds in most herbs, vegetables, and legumes. There are two different types of saponin compounds, which can be classified based on the nature of the aglycone bound to the oligosaccharide fragments, whether it is a steroid or triterpenoid. This paper is devoted to saponins with triterpenoid aglycone and aims to study the relationship between their content and several biological activities in different Juglans regia kernel extracts, including antioxidant, antimicrobial and antibacterial activities. Antioxidant activity was assessed against two free radicals: DPPH and ABTS. Oleanolic acid was used as a standard to quantify triterpenoid saponins, measured by the vanillin method, whereas Acarbose and Tetracycline were used as positive controls to evaluate the α-glucosidase inhibitory and antimicrobial activities, respectively, of walnut kernel extracts. Findings show that hydroalcoholic extract (EtOH 70%) has a considerable content of phenolic compounds, with 59.51 ± 0.26 mg GAE/g in total polyphenol contents, while the content of total flavonoids and condensed tannins were 3.14 ± 0.27 mg QE/g and 85.65 ± 0.37 mg CE/g of crude extract, respectively. In terms of antioxidant activity, the butanolic extract proved to be the most effective against DPPH with IC50 = 7.74 ± 1.49 µg/mL, while the precipitated extract showed the highest scavenging activity against the ABTS free radical with IC50 = 33.14 ± 2.96 µg/mL. In addition, butanolic and hydroalcoholic extracts of Juglans regia kernels showed an α-glucosidase inhibitory activity even more efficiently than synthetic drugs such as Acarbose, with IC50 values of 11.66 µg/mL and 16.17 µg/mL, respectively, versus 18.01 µg/mL in Acarbose. The evaluation of the antimicrobial activity against Bacillus subtilis, Escherichia coli and Klebsiella pneumonia strains revealed that some extracts could inhibit these bacteria. This study successfully assessed the bioactivities of the extracts, suggesting that the extracts of medicinal plants can demonstrate stronger bioactivity than pure synthetic compounds.

QV Analysis for the Identification of Vulnerable Zones to Voltage Collapse: A Study Case
Authors: Pereira Orlando , Rosés Rodolfo , Giménez María Del Carmen
Published: January 2023

Radial High-Voltage networks have problems ensuring voltage stability when a fault occurs. Among preventive actions for these events, installing reactive power compensation in the most vulnerable zones to voltage instability is an economical and simple alternative. Previous works have used the QV curves methodology based on contingency power flows to identify such zones. However, this method has been criticized because it does not consider the dynamical effect of some network elements that depend on the voltage levels, especially in contingency scenarios. This article proposes a QV curve analysis based on the operating point resulting from dynamic simulations to amend this critique. To evaluate the proposed procedure, the model of the Patagonian High-Voltage Network in southern Argentina is used through the PSS/E software with the help of the Python programming language. The results detect the most vulnerable areas to voltage instability after a fault occurs and the reactive power necessary to maintain voltage levels in an acceptable operating range. The proposed methodology can be applied to other networks. For example, it can be used in the Latin-American context to assess future network expansions, especially on those linking countries, such as Ecuador with Perú or Colombia, or even the Centro American Interconnected System.

Authors: Bagus Amlayasa Anak Agung , Riasning Ni Putu
Published: January 2023

The issue of fraud continues to plague organizations and stakeholders around the world because of its tremendous impact on business decisions. Starting from a financial scandal that resulted in the bankruptcy and collapse of a number of giant companies, such as Enron and WorldCom. This condition demands the attention of the auditor profession to actively find illegal acts in the company. Although the auditing standard (SA) No. 240 has determined that the external auditor is responsible for regarding fraud in an audit of financial statements, but in fact not all auditors can fulfill this responsibility. This study aims to examine the role of locus of control, task complexity, turnover intention and professional commitment to the acceptance of dysfunctional audit behavior. The population of this study is partner auditors, managers, supervisors, seniors and juniors who work in all KAP Denpasar City. The sample method used is non-probability with the snowball sampling method, obtained 81 respondents who are willing to fill out the questionnaire. The data analysis technique used to test the hypothesis is to use PLS-SEM analysis, with the help of SmartPLS 3.0 Software. The results show that the auditor's responsibility in detecting fraud directly can be increased by self-confidence and emotional intelligence. Other results show that although professional skepticism directly has not been able to increase the auditor's responsibility in detecting fraud, it will depend on emotional intelligence. It can be concluded that emotional intelligence is a pure moderator of the relationship between professional skepticism and the auditor's responsibility in detecting fraud.

The study adopted time series data that were obtained from the Statistical Bulletin of the Central Bank of Nigeria (CBN, 2020) and World Development Indicators (WDIs, 2020) for a period of 1981 – 2020. Autoregressive distributed lag (ARDL) and Fully Modified Ordinary Least Squares (FMOLS) techniques were adopted for short run and long run analyses. The results show that domestic credit to the private sector as a ratio of GDP has positive effect on Agricultural sector, but records negative effects on manufacturing sector, whereas, money supply as a ratio of GDP exerts negative effects on all the sectors in the short run. In the long run, money supply as a ratio of GDP also exerts negative effects on all the sectors save for services sector on which it has positive effects, while domestic credit as a ratio of GDP has positive long effects on all the sectors. The study identifies agricultural and services sectors as growth catalyzing sectors in relation to the influence of financial development. It is therefore recommended that policy makers take serious interest in the sectors, while further examining the challenges of failing financial development strategies on the manufacturing sector

As sustainable development has been widely recognized as an essential topic in the continuous advancement of human history, a wide variety of organizations around the world, including companies, have integrated sustainability into their development paths. A typical example of the integration of sustainability with a company's growth path is the company's sustainability report (SR). However, notwithstanding more and more companies are joining the sustainability reporting cohort, the standards for reporting are not uniform and the quality of reporting is uneven, which ultimately affects the quality of the organizational sustainability and the sustainability of the world as a whole. The purpose of this study is to investigate the nature and extent of sustainability reporting practices of a brewing company located in Minsk, Belarus. Data were collected from the company’s latest 2019 SR. Deductive content analysis was used to analyse the data, and the coding scheme used for content analysis was developed based on indicators from the Global Reporting Initiative (GRI). The results indicate a lack of disclosure of the SR of Belarusian brewing companies in terms of the content of biodiversity conservation and environmental complaint mechanisms. The results provide several practical implications for Belarusian brewing companies, regulators, and policymakers This study is one of the first to investigate the nature and extent of sustainability reporting practices in Belarusian brewing companies.

Diabetes is a serious defect that does not make the body to have enough insulin, and thereby allowing blood sugar to stay in the bloodstream more than the body requires and over time causes serious problems relating to health. So, predicting if a person has diabetes or not using the linear model surface, but a major challenge arises if there is heteroscedasticity in the model, which can make the least square estimates inefficient. So, there is a need to know the method that is best for detecting heteroscedasticity so as not to rely on inefficient model for predicting diabetes. This research therefore aimed at comparing the Breusch-Pagan-Godfrey (BPG), Harvey and Glejser tests for detecting heteroscedasticity in cross-sectional data. To achieve this, data were collected on Diabetes Pedigree Function (DPF), Plasma glucose concentration a 2 hours in an oral glucose tolerance test (G), 2-Hour serum insulin (mu U/ml) (I), and Triceps skin fold thickness (mm) (S) from National Institute of Diabetes and Digestive and Kidney Diseases (1990) comprising 768 observations. The data was divided into two, small sample and large sample. The result of the regression analysis showed that skin fold thickness is the most important factor that can predict diabetes in a patient, followed by plasma glucose concentration, and then by insulin. The result for heteroscedasticity showed that, heteroscedasticity is not present in small dataset using the three tests. However, for the large sample, both the Breusch-Pagan-Godfrey and Glejser detect heteroscedasticity, but Harvey did not. Hence, it is advisable to use either Breusch-pagan or Glejser tests because they are more sensitive to heteroscedasticity in diabetes patient data.
