Predictive analysis using artificial intelligence (AI) has transformed the landscape of forecasting analysis in various research fields. The advancements in AI modelling algorithms have enhanced decision-making, trend identification, and process optimization. In geotechnical engineering, AI assists in predicting soil behaviour, structural stability, and slope stability. The AI model discussed in this paper is the Adaptive Neuro-Fuzzy Inference System (ANFIS). In this study, the ANFIS model predicts slope stability by examining the Factor of Safety (FOS) value. Slope stability analyses reinforced with continuous bored pile walls generated by the numerical computation of the finite element method (FEM) in two dimensions (2D) and three dimensions (3D) are compared with the predictions of the ANFIS model. The numerical FEM computations employ PLAXIS 2D and PLAXIS 3D software. Meanwhile, the ANFIS model is designed within the MATLAB software platform involving 112 data samples. With six input pile parameters and one output, the finding shows that the ANFIS model can learn complex non-linear data and accurately predict the output. This is supported by the R² values of 0.9771 and 0.9965 from comparing the forecasting output with the 2D and 3D FEM outputs, respectively. Meanwhile, the low RMSE values of 0.0187 and 0.0180 each confirm this.

This paper presents dual band antenna by designing basic dipole antenna integrated with C-shaped patches structure for RFID applications. This C-shaped patch is inspired by E-shapes patch antenna that able to perform multiband frequency. The design of the equivalent circuit started with the fundamental circuit of impedance Zo and Z1 which functioned as a dipole antenna in single band. The parallel RLC circuit of impedance Z2 is added in the circuit as loaded patch has affected the resonating frequency. Variations of C1 and L1 on impedance Z1 effect a gap between the two resonance frequencies without changing the bandwidth by shifting the lower frequency. In addition, the variation of C2 and L2 on the impedance Z2 also affects the ratio between the two resonance frequencies but both frequencies are shifted and the bandwidth changes. Consequently, the dual band is presented at 0.915 GHz (UHF RFID) and 2.4 GHz (ISM RFID) by calculating the value of the resistance, inductance and capacitance. The data from electromagnetic simulation are compared with the data predicted by the antenna circuit modeling. The frequency sampled measurement data may be represented in the form of S-parameter in order to represent dependent data in a time domain simulator in P-SPICE software. The C-shaped design can be independently controlled to perform lower band and upper band by adjusting the width and length of the patch. The performance of the proposed antenna demonstrates the dual band antenna for RFID application with good agreements between measured and simulated results.

The visualization of mapping has aided researchers in gaining a better understanding and studying a specific area in a variety of professions. One of the well-known visualization software for mapping is the Geographic Information System (GIS). This work demonstrates the integration between an open-source GIS technology, named QGIS, and the Google Earth Pro programme in the mapping and analysis of electrical distribution substations. This integration shows the electrical substation data, the possible communication technology ranking, and a map that can be displayed and visualized based on the demographics. The QGIS in this study is used to reclassify the demographics into three main demographics: urban, suburban, and rural areas. On the other hand, the Google Earth Pro programme is used to map and visualize the overall electrical distribution substations alongside the communication technology ranking, based on the three main demographics. A case study using QGIS and Google Earth Pro was carried out in Area X, Malaysia for this investigation. Substation locations in Area X are mapped using Google Earth Pro, and the area’s demographics are categorized as part of the process. The features also enable the technology ranking to be displayed upon clicking the respective color-coded areas, where red represents urban area, yellow represents suburban and green represents rural This integration deems beneficial for future references on electrical distribution substations alongside the possible communication technologies.
(Post-)Socialist Housing and Aging in Neoliberal Riga
Authors: Lulle Aija
Published: April 2024

This article contends that envisioning the future of housing planning in post-socialist cities necessitates the acknowledgment of a pressing reality: Many societies are undergoing rapid aging and depopulation. Latvia’s capital city of Riga, the focal point of this study, stands at the forefront of these global trends. However, due to entrenched neoliberal practices that idealize youthful, robust, and entrepreneurial residents, considerations of aging are conspicuously absent from urban planning visions. Drawing on ethnographic research conducted in the capital city between 2021 and 2023, this article establishes a link between urban lived experiences while aging and the intersecting dynamics of housing. The critical analysis is informed by data derived from observations, conversations, media sources, official discourses, and perspectives gathered through expert interviews. Ultimately, this article advances an agenda aimed at urging people to think about more hopeful futures for aging in cities, an issue of paramount significance in the post-socialist societies of the 21st century.

Authors: Boeva Ksenia A. , Malyshkina Galina V. , Vyalykh Ivan V.
Published: April 2024

BACKGROUND: The human papillomavirus is an etiological factor and a biological carcinogen in tumor lesions and cancer. Currently, there are several known possible mechanisms of immune evasion of human papillomavirus. Therefore, early methods for diagnosing papillomavirus infection and effective treatments.
AIM: To analyze the cytokine profile should be established of dendritic cells in response should be determined to stimulation by peptide L2 of human papillomavirus type 16 in vitro.
METHODS: Dendritic cell cultures were obtained from the blood of donors without signs of the human papillomavirus infection in history. A culture without stimulation was used as a control. As experimental groups, cultures synthesized peptide with L2 of the human papillomavirus type 16 were used. Enzyme-linked immunosorbent assay was used to determine the levels of pro- and anti-inflammatory cytokines.
RESULTS: In comparison with spontaneous response in the control group after inoculation with peptide L2 of human papillomavirus type 16, increased IL-10, MCP-1, VEGF, IL-6, and IFN-γ concentrations and significant changes in IL-1β, IL-4, IL-8, IFN-α, and TNF-α concentrations were not detected.
CONCLUSIONS: The results confirm the ability of the human papillomavirus to evade the antiviral immune response by affecting the synthesis of several cytokines.

Published: April 2024

Uterine leiomyomas are the most common type of benign tumor that occurs in the female pelvis. Uterine leiomyoma is a tumor of smooth muscles. Its prevalence is higher in the reproductive age group and decreases after menopause. Giant uterine fibroids are a rare tumor of the uterus. Giant uterine fibroids, especially subcutaneous types, are complicated by malnutrition due to deterioration of their blood supply. The complaints of the patients are non-specific: an increase in the size of the abdomen, aching pains, sometimes difficulty urinating and defecating. A physical examination reveals a giant abdominal and pelvic formation. Ultrasound with Dopplerometry and contrast-enhanced MRI diagnoses a giant tumor next to the uterus with a heterogeneous structure and the presence of cystic cavities, which is difficult to distinguish from a true large ovarian tumor. The article illustrates the complexity of differential diagnosis of giant tumor of the uterus and ovaries. There are no significant differences between these tumors during ultrasound and MRI examinations. The final diagnosis can be made intraoperativery. The article presents a clinical observation of the giant uterine fibroids of a 48-year-old female patient. Ultrasound and contrast-enhanced MRI revealed a giant tumor of the right ovary, which occupied the entire abdominal cavity, of a heterogeneous structure. Intraoperatively, two tumors, intimately adjacent to each other, 31 cm and 28 cm in diameter, emanating from the isthmus of the uterus, were found. The final diagnosis of uterine fibroids was established histologically. Difficulties in differential diagnosis between uterine fibroids and ovarian tumors before surgery are associated with the large size of the tumor and the heterogeneity of the structure due to its malnutrition.

Natural products are appealing as anticancer agents because of their low toxicity profiles. Cinnamon is a naturally occurring component with a variety of pharmacological properties, including anti-oxidant, anti-microbial, and anti-cancer properties for cancer cell apoptosis. Therefore, the current studies were performed to investigate Anticancer Properties of Cinnamon Phytochemicals on Protein expression in Glioblastoma Multiforme Cell Lines (U87-MG) since the proteins are directly involved in cell survival and function.

Hot and cold extraction for Cinnamon performed from Cinnamon verum followed by phytochemicals tests. The Glioblastoma Multiforme Cell Lines U87 was subjected to cell viability by MTT Assay with Addition of cinnamon extract. The protein content was determined by spectrometric assay and its expression was investigated by SDS PAGE.

The aqueous Cinnamon extract found to be positive for Alkaloids, Tannins, Saponins, Flavonoids, Terpenoids (only for Hot extract), Phenols and Reducing sugars (only for Cold extract). The cell viability at cinnamon extract concentration of 0.051 mg/100μl is shown to be highest and cell death at maximum cinnamon extract concentration of 1.65 mg/100μl is highest. Further these phytochemicals together showed less protein content on cultured U-87 cells and displayed lower protein expression in gel band pattern when compared to their control.

The Cinnamon extract phytochemicals showed significant anticancer properties for reduced U87 cell viability with IC50 0.729.

Thus positive phytochemicals result has shown to play an important role in inhibiting cancer properties.by showing less protein content and its expression for cinnamon phytochemicals treated U87 cell lines.

Published: April 2024

This article proposes a method for modeling the probability of default, describes the statistical evaluation of the model, and presents a model of the software implementation algorithm. The algorithm automatically selects from the group of regression models where the models are both linear regression and various modifications of semi-logarithmic models and lag models for macro factors Xi,t,Xi,t-1, ...,Xi,t-TStatistical analysis is carried out using the coefficient of determination R-squared, p-value, VIF (variance inflation factor).The relevance of this topic is determined by the need for banking organizations to comply with international standards, such as International Financial Reporting Standards (IFRS 9) and the Agreement on Banking Supervision and Capital (Basel 3). These standards define credit risk assessment requirements and capital requirements. Adherence to these standards is important not only for ensuring the stability and reliability of the financial system, but also for maintaining the trust of clients and investors. Compliance with international standards also makes banks competitive in the global market and promotes investment inflows and the development of the financial sector.IFRS 9 can be presented in various mathematical models. The article proposes an approach to choosing the appropriate model for forecasting the probability of default. The described model selection method allows banks to choose the optimal default forecast assessment model within the framework of the given standard. This contributes to a more accurate and reliable assessment of credit risk, in accordance with regulatory requirements, which will provide banks with the means for better forecasting and management of financial resources, as well as risk reduction.The model selection methodology saves a significant amount of time and resources, since the search for the optimal model occurs automatically. This allows us to react more quickly to changes in the economic environment, improve decision-making strategies and manage credit risks, which is of great importance for financial institutions in a competitive environment.There is currently a war going on in Ukraine, and forecasting using current methods becomes a difficult task due to unpredictable stressful situations for the economy. In such conditions, standard models may not be sufficiently adapted to account for increased risk and volatility. The proposed approach allows finding more conservative forecasting models that can be useful in unstable periods and war.
Predictive model for a product without history using LightGBM. Pricing model for a new product
Authors: Kriuchkova Anastasiia , Toloknova Varvara , Drin Svitlana
Published: April 2024

The article focuses on developing a predictive product pricing model using LightGBM. Also, the goal was to adapt the LightGBM method for regression problems and, especially, in the problems of forecasting the price of a product without history, that is, with a cold start.The article contains the necessary concepts to understand the working principles of the light gradient boosting machine, such as decision trees, boosting, random forests, gradient descent, GBM (Gradient Boosting Machine), GBDT (Gradient Boosting Decision Trees). The article provides detailed insights into the algorithms used for identifying split points, with a focus on the histogram-based approach.LightGBM enhances the gradient boosting algorithm by introducing an automated feature selection mechanism and giving special attention to boosting instances characterized by more substantial gradients. This can lead to significantly faster training and improved prediction performance. The Gradient-based One-Side Sampling (GOSS) and Exclusive Feature Bundling (EFB) techniques used as enhancements to LightGBM are vividly described. The article presents the algorithms for both techniques and the complete LightGBM algorithm.This work contains an experimental result. To test the lightGBM, a real dataset of one Japanese C2C marketplace from the Kaggle site was taken. In the practical part, a performance comparison between LightGBM and XGBoost (Extreme Gradient Boosting Machine) was performed. As a result, only a slight increase in estimation performance (RMSE, MAE, R-squard) was found by applying LightGBM over XGBoost, however, there exists a notable contrast in the training procedure’s time efficiency. LightGBM exhibits an almost threefold increase in speed compared to XGBoost, making it a superior choice for handling extensive datasets.This article is dedicated to the development and implementation of machine learning models for product pricing using LightGBM. The incorporation of automatic feature selection, a focus on highgradient examples, and techniques like GOSS and EFB demonstrate the model’s versatility and efficiency. Such predictive models will help companies improve their pricing models for a new product. The speed of obtaining a forecast for each element of the database is extremely relevant at a time of rapid data accumulation.
Reaffirming the Queer Traumatized Self through Home: An Analysis of the Potential of Traumascapes in John Elizabeth Stintzi’s Vanishing Monuments (2021).
 
Authors: Corpus Navalón-Guzmán
Published: April 2024

This article examines John Elizabeth Stintzi’s novel Vanishing Monuments (2021) applying the views of trauma, queer theory, and the potential discussions around the notion of place. The main issue in Vanishing Monuments is how returning home implies grappling with a non-linear account of haunted memories related to identity and trauma. Drawing on Maria Tumarkin’s concept of traumascapes and connecting it to Cvetkovich’s notion of “queer trauma,” this article aims at disclosing the potentialities that physical spaces can have for the traumatized queer subject.  Firstly, this paper’s analysis will draw a connection between trauma and place to examine the function that the protagonist’s house has in the enactment of their trauma. Secondly, I will explore how the main character’s trauma is embodied in the narrative through a link between the concept of traumascapes and Ann Cvetkovich’s notion of queer trauma. This article concludes by evaluating the role that traumascapes might have for the queer subject to productively respond to trauma outside pathological boundaries.
Practical method in the diagnosis of diabetic ketoacidosis: end-tidal carbon dioxide
Authors: Kayalı Ahmet , Bora Ejder Saylav
Published: April 2024

Objectives: Diabetic ketoacidosis (DKA) poses a life-threatening risk in uncontrolled diabetes. Current diagnostic criteria rely on invasive measures, leading to potential delays in treatment initiation. This study aimed to assess the diagnostic utility of noninvasive end-tidal carbon dioxide (EtCO2) measurements in DKA patients.
Methods: A prospective, cross-sectional study was conducted in a tertiary-level Emergency Medicine Clinic from January 2021 to January 2023. Participants included adults with DKA symptoms and those with stable vital signs as controls. EtCO2 levels were measured using a capnograph device. Diagnostic criteria for DKA were blood glucose ≥250 mg/dL, ketonuria, ketonemia, and metabolic acidosis (pH<7.3 or bicarbonate <15 mEq/dL). Statistical analysis was performed using SPSS Statistics.
Results: Of 730 participants, 120 had DKA, 410 did not, and 200 served as controls. EtCO2 levels significantly differed between DKA, non-DKA, and control groups (P<0.05). EtCO2 correlated with pH, lactate, base deficit, and bicarbonate (P<0.05). ROC analysis showed an AUC of 0.86 for EtCO2 in diagnosing DKA (P<0.01), with 91.67% sensitivity and 74.39% specificity at a cut-off value 23.7.
Conclusion: This study suggests that EtCO2 measurement is a valuable noninvasive tool for diagnosing and assessing the severity of DKA in the emergency department. An EtCO2 threshold of <23.7 could prompt consideration of DKA in patients with elevated blood glucose levels. More extensive multicenter studies are warranted to validate these findings further. EtCO2 measurement could facilitate early DKA diagnosis and improve patient outcomes.
Mild hyperprolactinemia in clinical practice: the diagnostic “traps” and treatment strategy
Authors: Ilovayskaya Irena A. , Kruchinina Elena V.
Published: April 2024

Real world clinical practice frequently poses the question on the advisability of diagnostic and/or treatment interventions for increased prolactin levels of below 2500 mU/mL (100 ng/mL), which is commonly considered as mild and not unequivocally indicating a prolactinoma.
The aim of the review is to critically analyze the body of literature within the last 10 years on clinical and biochemical particulars of patients with mildly increased prolactin levels. We performed the search in Pubmed and RISC (Russian Index of Science Citation) databases with the keywords of “mild hyperprolactinemia” and “women” (or their Russian equivalents). After exclusion of the studies in patients with primary hypothyroidism or treatment with agents inducing prolactin secretion, as well as of clinical case descriptions, we selected 21 original papers with clinical and biochemical data of female patients with mild hyperprolactinemia (prolactin levels of less than 2500 mU/mL or less than 100 ng/mL). Symptoms of mild hyperprolactinemia include menstrual cycle disorders, anovulatory infertility and/or early pregnancy losses, breast disorders, psychoemotional and sexual disorders, and metabolic abnormalities. Repeated testing of prolactin levels to exclude potential stress related to the vein puncture allows for exclusion of 27% to 28% of the patients from further diagnostic work up. Confirmation of persistently increased prolactin levels warrants a magnetic resonance imaging study of the pituitary. Most patients with persistently increased prolactin levels by repeated tests would have pituitary abnormalities (in most cases, pituitary microadenoma). Taking into account the data on negative effects of even mildly increased prolactin levels on reproductive and metabolic health, it is reasonable to administer a first line agent cabergoline at doses ensuring normoprolactinemia. The results of studies indicate that treatment with cabergoline at doses necessary to normalize prolactin levels would lead to regression of menstrual dysfunction, decrease the probability of early pregnancy losses, improve metabolic parameters, promotes restoration of the sexual function, and diminishes the level of depression. This is especially important when planning pregnancy in patients with menstrual cycle disorders, infertility and/or early pregnancy losses.
Anti-tax evasion rules and the Autonomous Taxation of companies in Portugal
Authors: Rodrigues Carlos , Campina Ana
Published: April 2024

States, in their tax systems, create anti-tax evasion rules to try to eliminate the possibility of taxpayers engaging in behavior that harms the state in collecting the taxes that each citizen or company owes. Anti-tax evasion rules also aim to ensure that everyone contributes to public spending according to their real ability to pay, thus respecting the principle of equal contribution based on real and effective economic and financial capacity. Aware that there are companies that carry out harmful acts and thus reduce their economic and financial capacity to try to reduce their tax burden in terms of corporate income tax, the Portuguese legislator introduced autonomous taxation in corporate income tax, in the corporate income tax code, to try to eliminate belligerent behavior on the part of companies. Using the statistical data from the Autoridade Tributária e Aduaneira, and based on statistics from the tax and customs authority,  the study demonstrates the financial burden on companies that bear this type of taxation and compare it with the "Corporate Income Tax" charged annually by the State.

Authors:   The Korean Society of Calligraphy, Kim Byoung-ju
Published: April 2024

The purpose of this article was to explore new ways of teaching Chinese characters based on the cognitive patterns that learners have in advance. To this end, we identified the cognitive patterns of beginners who first encountered Chinese characters and presented teaching Chinese character and contents to suit their cognitive styles.
The learning habits of most beginners who first encountered Chinese characters is familiar with the learning habits of acquiring Hangeul and English. It is very difficult to expand the learning habits by adjusting the existing learning habits. Based on these points, the school devised a way to start Chinese character education in the existing learning habits framework. The method is to start Chinese character education by using strokes. The stroke can serve as the alphabet of Hangeul and the alphabet of English, making it a material for learners to easily access Chinese characters with a priori learning habits. In this article, the author suggested that strokes be classified into 20 categories and each stroke should be named and used for teaching Chinese character.
It is important to determine the learner's step-by-step learning according to the curriculum of education. It could be a way of teaching Chinese characters to teach them first when they first start Chinese characters. Still, strokes education is still unfamiliar as an educational method for Chinese characters. However, we hope that it will be a way for beginners who are new to Chinese characters to gain easier access to learning them.

Objective: This study examines the extent to which the experience of parenthood worries among Finnish first-time parents predicts the probability of a second birth, and whether the associations differ according to the parent’s gender or the sufficiency of spousal support in parenting.
Background: First-time parents’ withdrawal from having a second child has been connected to declining fertility rates in Finland and many other high-income countries; consequently, more understanding is needed about why parents potentially refrain from subsequent childbearing.
Method: We utilize longitudinal survey data collected from Finnish parents (N = 544) in three waves (2016–2020).
Results: The results show that experiencing parenthood worries significantly predicts the probability of a second birth. Specifically, the accumulation of parenthood worries predicted a lower probability of a second birth, and each additional worry decreased the probability significantly more for fathers compared to mothers. Although we found no gender differences regarding the associations between specific parenthood worries and the probability of a second birth, our results showed that fathers who worried about loneliness or having sole responsibility for parenting were less likely to have a second child than fathers with no such worries. In terms of the sufficiency of spousal support in parenting, we found, first, that among parents who received insufficient spousal support, those who worried about their parenting skills adequacy had a lower probability of a second birth than those with no such worries. Second, among parents with sufficient spousal support, worrying about their own ability to cope was associated with decreased probability of a second birth compared to those who did not experience such worry.
Conclusion: Our findings provide new insights into the potential influence of parenthood worries experienced by first-time parents and the role of spousal support in subsequent childbearing.
