Published: April 2024

Background

As depression is highly heterogenous, an increasing number of studies investigate person-specific associations of depressive symptoms in longitudinal data. However, most studies in this area of research conceptualize symptom interrelations to be static and time invariant, which may lead to important temporal features of the disorder being missed.

Objective

To reveal the dynamic nature of depression, we aimed to use a recently developed technique to investigate whether and how associations among depressive symptoms change over time.

Methods

Using daily data (mean length 274, SD 82 d) of 20 participants with depression, we modeled idiographic associations among depressive symptoms, rumination, sleep, and quantity and quality of social contacts as dynamic networks using time-varying vector autoregressive models.

Results

The resulting models showed marked interindividual and intraindividual differences. For some participants, associations among variables changed in the span of some weeks, whereas they stayed stable over months for others. Our results further indicated nonstationarity in all participants.

Conclusions

Idiographic symptom networks can provide insights into the temporal course of mental disorders and open new avenues of research for the study of the development and stability of psychopathological processes.

South Kalimantan Province has a fairly high dental caries problems, and one region with this problem is South Hulu Sungai Regency with a percentage of cases of 45.56%. Dental caries is influenced by various risk factors, including socioeconomic status, eating habits, general health, fluorine use, saliva, and caries experience. Risk assessment of dental caries can be done using the Caries-Risk Assessment Tool by the America Academy of Pediatric Dentistry (CAT-AAPD). This study aims to analyze the relationship between caries risk assessment using the CAT-AAPD method and the incidence of caries in children aged 6-8 years in South Daha District, South Hulu Sungai Regency. This is an observational analytic study with a cross-sectional approach. The population of this study was children in South Daha aged 6-8 years. The total number of samples was 104 selected using the simple random sampling technique. High category caries risk was most common in children suffering from dental caries in a very high category with 64 respondents (53.3%). The results showed that there was a strong relationship (< 0.05) between caries risk assessment using the CAT-AAPD method and the incidence of caries in children aged 6-8 years. The higher the risk of caries, the higher the incidence of dental caries. Parents’ increased awareness of maintaining children’s dental and oral health is important to reduce cases of tooth decay caused by dental caries, and they can determine the treatments that should be undertaken.

Denture cleansing is one clinical parameter of successful denture wearing. This study aims to examine the effect of the type of denture cleanser on porosity and discoloration of acetal resin as a denture base. Twenty-four samples of acetal resin with 10 mm in diameter and 2 mm in thickness were divided into four groups. Porosity was measured using the wet and dry sample measurement method, and color value levels were measured using chroma meter for all samples. All of the samples were soaked into four types of denture cleanser: distilled water, alkaline peroxide tablets, 0.2% chlorhexidine gluconate, and 0.5% sodium hypochlorite for seven days, then the final porosity and color value level were assessed. The results showed that there were significant differences between groups in porosity and in color change of acetal resin (p < 0.05). Pearson’s correlation test showed that there was a positive correlation between the porosity level and discoloration level of acetal resin (p < 0.05). The research discovered that the type of denture cleaner has a significant influence on the porosity and color change of acetal resin. Sodium hypochlorite has the highest porosity and color change when compared to other cleansing agents.

Authors: Dewi Anne Handrini , Triawan Andi , Jansen John
Published: April 2024

Cinnamaldehyde is an organic component in cinnamon and has anti-inflammatory, antibacterial, and osteogenic properties. Loading cinnamaldehyde with a concentration of 4% into an artificial scaffold from gypsum calcium carbonate hydrogel could reduce inflammation, accelerate healing, and promote new bone regeneration at bone implantation surgery. The aim of this study was to investigate the impact of cinnamaldehyde loaded on gypsum-hydrogel calcium carbonate on the process of wound healing and bone regeneration in rats. Implantation of bone scaffolding from gypsum hydrogel calcium carbonate with an addition of cinnamaldehyde was performed on 20 5-month-old Sprague-Dawley rats weighing 300-350 g in an artificial defect of condyle femoris bone dexter and sinister. Group A was a control with gypsum only, while groups B, C, and D were given gypsum and CaCO3 with a combination of cinnamaldehyde or dehydrothermal treatment (DHT). Euthanasia was performed after implantation at 1, 4 and 8 weeks for 4 groups (n = 3). Femoris condyle bone was cut, made into histological preparations by hematoxylin eosin (HE) staining, and analyzed descriptively. The results showed that the loading of cinnamaldehyde on the scaffold was effective in weeks 1 and 4, but after 8 weeks of implantation, cinnamaldehyde was observed to inhibit defect closure. The cinnamaldehyde group combined with dehydrothermal (DHT) treatment was found to be better than those without DHT.
Corporate Transformation, Income Inequality, and Consumer Commodity Choice: The Economic Cycle in the Rise and Fall of Industries
Authors: Yang Huan
Published: April 2024

In a multi-industry closed economy with constant productivity, this paper innovatively constructs an inter-industry transformation mechanism, and find the clustering behavior of enterprises transforming according to the industry prosperity will lead to the inter-industry evolution, which will lead to the fluctuation of the business cycle. We also find that the extreme boom/bust of a single industry will greatly increase the degree of income inequality, and when the industrial pattern composed of the development of different industries is in a balanced state, income inequality is at the lowest point of the economic cycle; At the same time, on the demand side of economic operation, we apply the heterogeneous commodity selection theory of utility maximization in classical economics to the household sector with two consumption preferences (high-grade and ordinary) for the first time, and finds that the implementation of diversified commodity basket subsidies for households in need of relief will promote the improvement of total social utility. This is the strong false evidence of the utilitarian view of social welfare; Finally, we study the government's attitude towards enterprise transformation, allowing the government to adjust the industrial structure of the economy by imposing macro-restrictions on the minimum number of companies in a single industry. It finds that enterprise transformation under excessive restrictions will lead to the failure of the market mechanism, making it impossible to rationally allocate production resources among industries, resulting in low GDP and low social utility. The extremely loose transformation supervision will have a profit impact on the high-end goods industry.

Bridging the Semantic Gap
Authors: Wasserman-Amir Dalit
Published: April 2024

The present research explores how Hebrew speakers derive meaning from distant noun collocations drawn from the poetry of Yehuda Amichai. The research participants completed a questionnaire where they had to rate the distance between collocated nouns extracted from Yehuda Amichai’s poetry and propose a connection between them without receiving any context or explanation. The questionnaires’ analysis offers a glimpse into the diverse ways in which the responders attempted to reconcile distant nouns. Their solutions included phonetic and morphological associations, morphological derivations, and even back-formations based on homonyms. Their solutions indicate that language speakers make great efforts to find semantic affinity even when the combination between distant word pairs appears meaningless.
Meursault as an Embodiment of Markata Vairagya (Monkey Detachment) in Albert Camus’s The Outsider
Authors: Behera Dr. Pradip Kumar
Published: April 2024

Meursault, the protagonist in Albert Camus’s The Outsider, is emotionally detached. He shows very less concern for life, death, relationship and everything. He intends to get happiness and peace of mind being detached. He holds the belief that emotions are no source of pleasure, but rather a source of trouble. He also regards all emotional expressions as absurd and meaningless. But his detachment turns into emotional involvement and attachment in many cases in the novel. The feeling of unintentional attachment and intentional detachment run parallel in case of Meursault. He shows unintentional attachment and emotion. He is again and again drawn towards sensual pleasure. He carves for physical relation with his beloved Marie. He also possesses the felling of anger, sadness, anxiety, fear etc. which are the outcome of attachment. He is unconsciously enforced to get emotionally involved with people. He sharpens his physical senses through focusing on their satisfaction. The article discusses how Meursault embodies a type of ‘Vairagya’ (Detachment) which is described as “Markata Vairagya” (Monkey Detachment) in Hindu Philosophy. Such type of detached person deliberately detaches himself emotionally from people to gain happiness, but unaware, he is drawn into emotional involvement with others.

A Baseline Study of Bacterial Pathogens in Greywater Samples in Jordan Using Ribotyping
Authors: Arabeyyat Zeinab
Published: April 2024

As Jordan advances in an attempt to promote greywater reuse, it is important to investigate the composition of bacteria in these new sources. To evaluate the presence of enteric pathogens in greywater, a pilot study investigating enteric pathogens in household washing machines and kitchen sink effluents from residential premises was conducted. In the culture-dependent method, bacteria were identified after using Sanger sequencing of 16S rRNA. Bacteria in the phylum Proteobacteria have been found to be the most abundant phyla, which may indicate that they play an important environmental role and might be representative of adaptation to different environments. Klebsiella sp. and Pseudomonas sp. were the two major genera found in this study and accounted for 78.57% of the total isolates. This is the first investigation of enteric pathogens in household washing machines and kitchen sink effluents in Jordan. To my knowledge, no study has identified the microbial hazards associated with greywater reuse in Jordan yet. Additional research with more adequate methodology is needed to assist our findings.

Automation of production management refers to the most effective directions of information technology application. Complex technological processes, rapid change of prices for raw materials and products, frequently changing situation on the labor market make the management of the enterprise makeprompt and optimal decision based on the analysis of a large amount of information. Introduction of computer technology to the processes of information exchanges between the enterprise departments not only accelerates them, but also significantly reduces the inconsistency of documents that are different segments of the same data. A reasonable system of security and data backup allows to avoid losses and unauthorized access to important information. The aim of the research is to develop a mathematical model to solve the problems of operational production planning. This paper considers mathematical models for describing the technological process of downhole pumpproduction, taking into account different technologies of manufacturing components and multivariate use of materials. The obtained results can be the basis for the development of information-analytical system, which allows to automate the process of production program planning in real time. A manufacturing enterprise engaged in manufacturing of downhole pumps produces a certain number of products: plug-in, pipe and other types of pumps. We will solve the problem of maximizing the number of complete pumping equipment produced under given constraints on available material stocks. The problem of finding the optimal production program maximizing the number of manufactured complete products of the industrial enterprise for the manufacture of well pumps is defined. The described problem takes into account the production features of pumping equipment manufacturing, so its solution may lead to an increase in production efficiency at this enterprise.

Carbonnanostructures attract an increasing attention among researchers in various spheres due to their unique physical and chemical properties. The article considers the application of numerical methods to find solutions of different nanostructure formation models. Modelling problem of carbon nanostructure synthesis is decomposed into six subproblems and time taken to their solution has been analyzed. Anassumption was made that the most effective optimization is that of electromagnetic field parameter analysis algorithm as this subproblem requires the least time to solve. It was shown that modern mathematical models applied for carbon nanostructure synthesis description are characterized by high dimensions causing difficulties in calculation of model parameters. The results with low computational efficiency are more evident in case of parallel approach as computation flows have to be stopped from time to time to determine the stopping condition meeting. Theimplementationofdistributedparallelstructuresis assumed to provide parallelizing of computational processes within distributed computational environment. To solve the present problem method of multiprogramming has been applied.

Published: April 2024

The social and economic development sustainability depends on the numerical reproduction of population. Here, an important factor is the populationwelfare, the income received or the level of consumption. The possibility of a birth rate increase and a mortality decrease in the regions of the Russian Federation depending on the consumption variation is being studiedin this article. The information base of the research contains official statistical data on the indicators of birth rate, mortality and per capita consumption of the population in the Russian Federation’s regions. Numerical analysis and modeling of birth rate and mortality dependence on consumption were carried out according to the data reflected in the federal statistical accounting system for the period of 2011-2021 for 85 regions of the Russian Federation. The article considers techniques, algorithms and methods of mathematical and statistical modeling.The calculations of birth rate and mortality dependence on the per capita consumption factor made it possible to distinguish three main clusters among the regions of the Russian Federation.The first cluster with a specific monthly consumption of 13-46 thousand rubles contains 75 regions. The second cluster consists of regions with a specific monthly consumption of 13 thousand rubles and less. It includes Altai, Dagestan, Ingushetia, the Kabardino-Balkarian Republic, Kalmykia, the Karachay-Cherkess Republic, Mordovia, Tyva, the Chechen Republic. The third cluster includes the city of Moscow with the highest specific consumption in the Russian Federation (over 51 thousand rubles per month). Consumption values are calculated at comparable 2021 prices.The study revealed that for areas with average consumer spending, a 2-fold increase in consumption will increase the birth rate by 16.3% and reduce mortality by 15.9%.The obtained functions of a possible increase in the birth rate and reduction of mortality of the population can be used for demographic forecasts, as well as socio-economic development strategies

Published: April 2024

The article develops a simple, efficient and effective method for fast discrete Fourier transform, which allows to calculate Fourier coefficients (bins) independently at positive and negative frequenciesfor finite complex and real signals.The algebraic and matrix forms of the discrete Fourier transform and the structure of its basis - the basis of exponential Fourier functions - are briefly considered.The main section of the article discusses generalizations of the discrete Fourier transform in the form of parametric discrete Fourier transforms.Two types of parametric discrete Fourier transforms have been studied, that have a parameter θ in a frequency variable or a parameterθ in a time variable. The structure and properties of the bases of these transformations being the bases of parametric discrete exponential functions were analyzed and investigated.Based on parametric discrete Fourier transforms of the second type, a new method for constructing algorithms for fast discrete Fourier transforms of complex and real signals has been developed and described in detail.In order to verify the obtained theoretical results, a step-by-step testing of a new method for constructing algorithms for fast discrete Fourier transform of finite complex and real signals was carried out.Testing of a new method for constructing algorithms for fast discrete Fourier transform of finite complex and real signals has fully confirmed the validity of the obtained results. For finite complex signals, the result obtained is (until the corresponding practical problem appears) of a theoretical nature.For finite real signals, the obtained result has theoretical and important practical significance.Since they have a redundant characterdue to the property of Hermitian symmetry of the finite real signalspectra.They can only be calculated at positive or negative frequencies.This allows to reduce the required amount of memory and the number of basic operationsfor finite real signals.

Published: April 2024

This article presents and describes a digitalizationmodel of a production division to provide intelligent decision support. The model includes four levels: the level of production resources, the level of information systems, the level of BI and the level of the decision maker.The main processes taking place in production are given. These processes relate both to the main ones - directly related to production, and to auxiliary ones - the processes of providing production with necessary items (materials, tools, blanks, components, documentation, other resources, and etc.). The problems of the topic under consideration, which mainly consists in the absence of an integrated approach to processmanaging, leading to processed informationfragmentation and, often, the lack of interconnection between the processes and, consequently, theirmutual effect,are described. Due to multitasking, as well as a large number of processed objects and connections, the use of intelligent control of these processes is necessary to ensure the successful operation of production. The main objects of digitalization of the production division are suggested. It is proposed to integrate the existing systems into a single digital space using intelligent technologies. The information about previously developed prototypes of information systems and their testing is provided.Providing production with digital technologies both in accordance with the concept of 'Industry 4.0' and for the purpose of their further development and transition to 'Industry 5.0' will increase the manageability of production processes and, as a result, the effectiveness of the production division. As a result, the necessary 'basic set' of software and hardware has been identified, which introductionwill increase the level of digitalization and intellectual manageability of the division.

Published: April 2024

The description of the billet and the tool, being used to simulate the technological process by means of the Q-Form software, is given in order to further mode determination of reducing long-length pipe blanks with shaped holes. The results of the study were achieved by modeling tools and billets with an external diameter of 16.0...16.5 mm, used to produce products in mechanical engineering. Diagrams of emerging forces and average stresses at matrix and billet contact points, formed during the reduction process, are presented. Three contact zones: the beginning of pressing the billet into the matrix, in the middle and at the end of the reduction process are considered. The influence of the billet outer diameter value on the technological parameter of the process is considered (evaluated). It was revealed that larger billet outer diameter causes elongation during the reduction process. In addition, the construction of mathematical models and the determination of process parameters of reducing long-length pipe blanks with shaped holes is described based on numerical methods, namely the finite element method, which is used in the ongoing study. Depending on the technological process features, various schemes of contact interaction and the action of technological load distribution has been identified. The most widely used reduction schemes are considered. The implementation of the well-known Lagrange equation by the finite element method for tools and billets involved in the technological process requires the need to solve five related systems of equations given in this article. Strains in each discrete element of the mathematical model are determined by the Cauchy equation. The elastoplastic problem is solved for the developed boundary conditions. The purpose of the study is to build mathematical models, providing results to analyze the technological parameters of reducing long-length pipe blanks with shaped holes and conclude that the technology in question can be used in various modes, taking into account deviations in geometry to obtain high-quality shaped profiles of the rifling parts.

Published: April 2024

Welding is one of the most commonly used methods of manufacturing critical steel structures: beams and supports of buildings and bridges, frames and bodies of rolling stock. At the same time, the manufacturing quality of welded joints directly affects the strength and durability of structures. Currently used weld manufacturing technologies include ultrasonic testing in order to increase the reliability and failure-free operation of welded structures. The methods of ultrasound control are regulated by several standards: GOST R ISO 17640, STO-GC Transstroy-005-2007 and GOST R 55724, each of which defines different ways to adjust sensitivity. In these conditions, the issue of analyzing the ultrasound control results performed in accordance with various regulatory documents is relevant. A comparative analysis of the ultrasonic inspection sensitivity distribution over the weld thickness was carried out using two cylindrical control reflectors and tuning samples with reflectors of the lateral cylindrical hole and notch types. A sample with cylindrical reflectors with diameters of 2 mm and 3 mm was developed and manufactured to adjust the sensitivity of welded joint ultrasonic inspection by the DAC method according to ISO 17640 and two-zone control by direct and single-reflected beams according to STO-GC “Transstroy”-005-2007. The regularities of amplitude changes and detection coefficient of reflector signals located at different depths with different methods of sensitivity adjustment at a frequency of 5 MHz have been experimentally established. It has been experimentally shown that the use of cylindrical reflectors and notches for leveling sensitivity in the depth of the welded joint with a product thickness of up to 15 mm is equivalent with an unevenness of no more than 1.5 dB. To ensure uniform sensitivity with an uncertainty of no more than 2 dB, a two-parameter RF can be used, adjusted by three reflectors located at the boundaries of the control zone and at the midpoint.

This article analyzes the results of a sociological study to identify the shortcomings of the in-house training system for production workers at a machine-building enterprise. There are described the goals, objectives, research methods used during sociological research. The need for research is due to the fact that the operating conditions of modern industrial enterprises are changing, the development of scientific and technological progress is accelerating, and the digital transformation of production processes at enterprises is underway. The successful implementation of these processes is not possible without the formation of appropriate competencies among production workers, which can be developed both in the vocational training system outside the enterprise and within the framework of in-house training. The main idea of forming and adjusting the system of in-house personnel training is to create the opportunity to train workers directly on site without interrupting the main production process. Despite the accumulated theoretical and practical knowledge about the organization of the training process in production, there is a need for in-depth study of it for different categories of workers and systematization of this material. Summarizing the results of the study of the peculiarities of the functioning of the in-house training system, a conclusion was made about its imperfection and the need for modernization in terms of the methods used, the efficiency of presenting the material, the focus on the practical needs of workshop workers, the possibility of using the acquired skills in production, and the novelty of the taught material. Based on the data obtained as a result of the sociological study, a number of measures were proposed to improve the system of organizational training of workers of machine-building enterprise.

Abstract: The system aims to give CCTV cameras the ability to detect suspicious activity, without human intervention.The goal of this paper is to identify suspicious activity for Surveillance and alert the shop owners when suspicious activity is detected. Electronic Article Surveillance (EAS) systems are widely used in today’s retail stores, but this system is not capable enough as the shoplifters can easily remove the tagor label from the product. Hence, this system aims to takereal-time videos from CCTV as an input and pass it to theCNN model created with the help of transfer learning anddetect ‘Shoplifting’, ‘Robbery’ or ’Break-In’ in the store and notify it to the owners as soon as it occurs. Finally the main motive is to provide a system that detects suspicious activities without human intervention and generates alert, thus making a huge revolution in today’s surveillance system.

Abstract: Fungal infections have been a serious problem since long time. However, development of new antifungals has improved the situation and helped a lot in overcoming the problems caused due to invasive fungal infections. It is very crucial to understand the mechanism behind fungal infections and generation of resistance. Extensive use of azole antifungals has caused their resistance leading to medication failure. Focus on antimicrobials got a boom after Covid 19 outbreak but still fungal infections are least focused. Fluconazole a widely used antifungal have no action against Candida albicans. Due to excessive use resistance have been created this reason warns us that there is a great need to introduce new and better antifungals in the market. Beside this new antifungal like Echinocandin and second generation of triazole antifungals are clinically important. On the top of this Posaconazole (triazole second generation) is the azole active against Zygomycete fungi. Combination therapy is an additional method for treating invasive fungal infections. However, in the end, there is a mismatch between the supply and demand for antifungals.an additional method for treating invasive fungal infections. Hence need to introduce novel antifungals have become very important. The main aim of this article is to focus on the emerging fungal infections and mechanism of resistance along with study of fluconazole as antifungal agents.

Abstract: In the financial markets, accurate prediction of stock prices is important for investors seeking to optimize returns. This paper presents a project focused on Stock Price Prediction Using LSTM and Alert System. The Long Short-Term Memory (LSTM) models, known for their ability to capture intricate patterns in sequential data, our project aims to forecast stock prices with enhanced accuracy and reliability. Additionally, we introduce an alert system. This supplementary feature enables users to set alerts based on specific stock price, enhancing timely responses to market changes. The methodology involves rigorous data analysis using Yahoo Finance data, preprocessing techniques, and the implementation of LSTM models for predictive modeling. Through comprehensive evaluation and experimentation, we demonstrate the efficacy of LSTM models in generating accurate stock price predictions.

Breast cancer is a global public health issue, in Brazil, affecting approximately 73,610 new cases annually. The diagnosis impacts the patient’s life and their family, triggering a range of negative emotions and social consequences. The journey begins with the detection of a lump, followed by internal conflicts such as denial and acceptance. The complexity of breast cancer is due to multiple genetic factors. Genetic mutations influence the risk and treatment, with genetic sequencing allowing for advanced diagnoses. The psychological impact is a frequent concern, emphasizing the need for effective communication between doctor and patient. The patient described here has triple-negative breast cancer and a genetic mutation in the RAD51D gene, with the psychological assessment revealing insecurity, a quest for information, and concerns about treatment. The lack of personalized psychological support is evident, underscoring the importance of medical-psychological integration for a more holistic approach. This analysis provides insights into the emotional aspects of genetic mutation diagnosis in breast cancer, emphasizing the ongoing need for collaboration between medicine and psychology to enhance support for patients facing breast cancer and its genetic implications.
