OBJECTIVE

Risk for memory decline is a common concern for individuals with temporal lobe epilepsy (TLE) undergoing surgery. Global and local network abnormalities are well documented in TLE. However, it is less known whether network abnormalities predict postsurgical memory decline. The authors examined the role of preoperative global and local white matter network organization and risk of postoperative memory decline in TLE.

METHODS

One hundred one individuals with TLE (n = 51 with left TLE and 50 with right TLE) underwent preoperative T1-weighted MRI, diffusion MRI, and neuropsychological memory testing in a prospective longitudinal study. Fifty-six age- and sex-matched controls completed the same protocol. Forty-four patients (22 with left TLE and 22 with right TLE) subsequently underwent temporal lobe surgery and postoperative memory testing. Preoperative structural connectomes were generated via diffusion tractography and analyzed using measures of global and local (i.e., medial temporal lobe [MTL]) network organization. Global metrics measured network integration and specialization. The local metric was calculated as an asymmetry of the mean local efficiency between the ipsilateral and contralateral MTLs (i.e., MTL network asymmetry).

RESULTS

Higher preoperative global network integration and specialization were associated with higher preoperative verbal memory function in patients with left TLE. Higher preoperative global network integration and specialization, as well as greater leftward MTL network asymmetry, predicted greater postoperative verbal memory decline for patients with left TLE. No significant effects were observed in right TLE. Accounting for preoperative memory score and hippocampal volume asymmetry, MTL network asymmetry uniquely explained 25%–33% of the variance in verbal memory decline for left TLE and outperformed hippocampal volume asymmetry and global network metrics. MTL network asymmetry alone produced good diagnostic classification of memory decline in left TLE (i.e., an area under the receiver operating characteristic curve of 0.80–0.84 and correct classification of 65%–76% of cases with cross-validation).

CONCLUSIONS

These preliminary data suggest that global white matter network disruption contributes to verbal memory impairment preoperatively and predicts postsurgical verbal memory outcomes in left TLE. However, a leftward asymmetry of MTL white matter network organization may confer the highest risk for verbal memory decline. Although this requires replication in a larger sample, the authors demonstrate the importance of characterizing preoperative local white matter network properties within the to-be-operated hemisphere and the reserve capacity of the contralateral MTL network, which may eventually be useful in presurgical planning.

Published: May 2023

This study focused on the Universal Middleware design for the IoT (Internet of Things) service gateway for the implementation module of the convergence platform. Recently, IoT service gateway including convergence platform could be supported on dynamic module system that is required mounting and recognized intelligent status with the remote network protocol. These awareness concepts support the dynamic environment of the cross-platform distributed computing technology is supported by these idea as a Universal Middleware for network substitution. Distribution system commonly used in recent embedded systems include CORBA (Common Object Request Broker Architecture), RMI (Remote Method Invocation), DCE (Distributed Computing Environment) for dynamic service interface, and suggested implementations of a device object context. However, the aforementioned technologies do not support each standardization of application services, communication protocols, and data, but are also limited in supporting inter-system scalability. In particular, in order to configure an IoT service module, the system can be simplified, and an independent service module can be configured as long as it can support the standardization of modules based on hardware and software components. This paper proposed a design method for Universal Middleware that, by providing IoT modules and service gateways with scalability for configuring operating system configuration, may be utilized as an alternative. This design could be a standardized interface provisioning way for hardware and software components as convergence services, and providing a framework for system construction. Universal Middleware Framework could be presented and dynamic environment standardization module of network protocols, various application service modules such as JINI (Apache River), UPnP (Universal Plug & Play), SLP (Service Location Protocol) bundles that provide communication facilities, and persistence data module. In this IoT gateway, management for based Universal Middleware framework support and available for each management operation, application service component could be cross-executed over SNMP (Simple Network Management Protocol) version 1, version 2, and version 3. The way of SNMP extension service modules are conducted cross-support each module and independent system meta-information that could be built life cycle management component through the MIB (Management Information Base) information unit analysis. Therefore, the MIB role of relation with the Dispatcher applied to support multiple concurrent SNMP messages by receiving incoming messages and managing the transfer of PDU (Protocol Data Unit) between the RFC 1906 network in this study. Results of the study revealed utilizing Universal Middleware that dynamic situations of context objects with mechanisms and tools to publish information could be consisted of IoT to standardize module interfaces to external service clients as a convergence between hardware and software platforms.

Hasil analisis menunjukkan bahwa tarikan perjalanan (Y) dipengaruhi oleh tujuan berkunjung (X4), pelayanan (X6) dan ketersediaan fasilitas (X8). Model terbaik untuk meramalkan tarikan perjalanan pengunjung Hilal Point Kota Parepare adalah Y = -1,460 + 0,502 X4 + 0,221 X6 + 0,166 X8. Artinya jika tujuan berkunjung mengalami kenaikan satu satu, maka tarikan akan mengalami penurunan sebesar 0, 502 atau 50,2%. Jika pelayanan mengalami kenaikan satu satu, maka tarikan akan mengalami penurunan sebesar 0,221 atau 22,1%. Adapun jika ketersediaan fasilitas mengalami kenaikan satu satu, maka tarikan akan mengalami penurunan sebesar 0,166 atau 16,6%.

 

Abstract

Culinary tourism area is a type of land use that can cause trip attraction. Hilal Point is a new culinary tourism area in Parepare. The area is quite large with two main buildings, the food court area and the coffee shop area, which are equipped with various interesting facilities. However, this effects a strong trip attraction to the surrounding area which also led to traffic jams on Abdul Kadir street where the Hilal Point located. Therefore, this study was carried out in the form of a trip attraction analysis to determine the characteristics of the visitor, the factors that trigger the attraction and the model of the trip attraction using multiple regression analysis methods through SPSS software version 26. The results of the analysis shows that traffic attraction (Y) is been affected by purpose of visiting (X4), service (X6) and availability of facilities (X8). The best model to predict the trip attraction of Hilal Point visitors in Parepare is Y = -1,460 + 0,502 X4 + 0,221 X6 + 0,166 X8. This means that if the purpose of visiting increases by one, then the attraction will decrease by 0,502 or 50,2%. If the cafe’s services increases by one, then the attraction will decrease by 0,2211 or 22,1%. And if availability of facilities increases by one, then the attraction will decrease by 0,166 or 16,6%.

The use of synthetic dyes has been found to have negative environmental impacts, leading to a growing demand for natural alternatives. This study explores the potential of bacterial pigments, derived from microorganisms, as a sustainable alternative for textile dyeing. The first chapter examines the ecological impact of synthetic dyes and the potential of natural dyes, including bacterial pigments, as a sustainable alternative. Biodegradability and life-cycle-assessment are discussed in this chapter since they are important factors to evaluate the environmental impact of any substance. The second chapter discusses the potential for bacterial pigments to functionalize textile materials with new therapeutic properties, including antifungal and anti-inflammatory effects. Additionally, some bacterial pigments can be used as semiconductors for electronics. The third chapter outlines the challenges of using natural pigments in textile production and suggests techniques to improve colourfastness. The chapter also highlights the successful uses of pigments such as anthraquinone, carotenoid, violacein, melanin, and prodiginine in textile colouring. Finally, the future perspectives section identifies potential areas for further research and development in the field of bacterial pigments, which could revolutionize the textile industry towards a more eco-friendly and innovative approach to textile production.

The aim – to study the relationship between the sST2 level and the degree of epicardial blood flow recovery and with the heart failure (HF) development in 6 month follow-up in patients with STEMI after PCI.Materials and methods. The study involved 61 patients with STEMI – 51 (83.6 %) males and 10 (16.4 %) females, with average age of 59.85±10.01 years. Standard clinical and biochemical parameters were determined, as well as sST2 level was measured by enzyme immunoassay using a reagent kit «Presage ST2 analysis, Critical Diagnosis» (USA) in all patients, on the first day of the disease. Patients were divided into two groups depending on the degree of blood flow recovery in a culprit artery (TIMI) The first group (n=12) included patients with TIMI 0, I, II, the second group (n=49) with TIMI III.Results and discussion. The sST2 level was significantly higher in the first hours of the disease in the group with unrepaired or decreased epicardial blood flow (TIMI 0–II) after PCI (p=0.003). ROC analysis showed that sST2 levels above 34.2 ng/ml, detected in the first hours of the disease, is an independent marker of adverse revascularization (TIMI 0–I) in patients with STEMI with a sensitivity of 92.3 % and a specificity of 62.5 %; the area under curve (the AUC) is 0.8 (95 % CI=0.651–0.873; p=0.001). When conducting a univariate (χ2=17.741; p=0.04) and multivariate (χ2=9.293; p=0.004) logistic analyzes, sST2 was a significant influencer of the unfavorable outcome of epicardial vascular revascularization (TIMI 0–ІІ).Conclusions. sST2 is highly associated with the degree of epicardial blood flow recovery in patients with STEMI and is of great clinical importance as diagnostic marker.

The aim – to determine a prognostically significant set of anamnestic (primarily cardiovascular) risk factors and indicators of the initial clinical condition in the population of patients with COVID-19, on the basis of which to develop a scale for assessing the clinical condition to identify patients with a more severe subsequent course of the disease for the individualization of treatment tactics.Materials and methods. The retrospective analysis included data on 104 patients with COVID-19 (50 men and 54 women, aged 24 to 84 years), who during 2020-2021 underwent treatment (16 days) in clinics of Ukraine within the framework of the program for studying the effectiveness of treatment COVID-19. Risk factors (advanced age, inflammatory diseases, hypertension, obesity, diabetes, coronary heart disease, heart failure (HF)), dynamics of the clinical state (heart rate, body temperature, blood pressure, SpO2, respiratory rate (RR), clinical symptoms and signs from all systems of the body) were assessed. Based on the dynamics of the clinical condition (according to a specially developed scale), all patients were divided into subgroup A (66 patients, more severe hospital course of COVID-19, ≥ 7 points) and subgroup B (38 patients, milder course of COVID-19, < 7) points).Results and discussion. Among the anamnestic risk factors (RF) of a more severe hospitalization for COVID-19, the following were more informative than others: age > 53 years (HR 1.8 (1.11–3.02)), history of coronary artery disease (HR 1.42 (1.09–1.85)) and SN (HR 1.67 (1.41–1.96)), as well as a model built taking into account all the estimated RFs according to their significance (HR = 1.88 (1.37–2.74), area under the ROC curve (ROC) 0.73). Among the clinical markers (CM) of the first day, the most informative were: RR > 20/min (HR 1.74 (1.10–2.74)), body temperature > 37.8 °C (HR 1.48 (1.13–1.94)) and a model with eight KM (HR 2.45 (1.55–3.87), ROC 0.80). The obtained scales were additive: the combined scale of RF and CM had ROC 0.84, value > 21 units on the first day of COVID-19 had a sensitivity of 76 % and a specificity of 76 % (HR 2.38 (1.58–3.58)) in predicting the adverse course of the disease during the next 16 days.Conclusions. The risk assessment system developed by us, based on clinical and anamnestic data, on the first day of treatment for COVID-19 allows predicting a more severe course of the disease. The data obtained by us require further study in a prospective study.

The special place of nebivolol in the treatment of essential arterial hypertension (AH), coronary heart disease (CHD) and heart failure (HF) is outlined. The drug does not possess a diabetogenic activity with a long-term use, and impacts favourably on the parameters of lipid and carbohydrate metabolism. In CHD patients, nebivolol demonstrates the antianginal and antiischemic activities, and reduces the frequency of angina recurrence after coronary artery interventions. The drug is well tolerated and characterized by a high effectiveness with respect to the reduction of mortality rates in patients with chronic HF over 70 years of age, regardless of the left ventricular ejection fraction. Vasodilating BB are preferred in the treatment of CHD patients with type 2 diabetes. In case of non-obstructive coronary lesions, nebivolol is chosen among existing BBs for the treatment of microvascular angina. The use of nebivolol in AH patients, in addition to the antihypertensive effect, is characterized by a favorable impact on the function of endothelium, the metabolic profile, central hemodynamics, health-related quality of life of patients, as well as more favorable profile of side effects.

Results: UTI was confirmed by urinary culture in 6 infants (12%). E. coli was the most common isolated microorganism. UTI was more common in female patients during the first 2 months of life (66%). Irritability was the most common associated clinical feature (83%). Conjugated bilirubin was found to be the most raised fraction among jaundiced infants with UTI. Jaundice resolved gradually upon treating UTI with proper antibiotics.
Conclusions: UTI was found in 12% of infants of less than two months of age with prolonged neonatal jaundice; urine culture should be considered as a part of the diagnostic evaluation for any infant with prolonged neonatal jaundice beyond 14 days of life with unexplained etiology.

Gender in Kinderkrippen
Authors: Schaich Ute
Published: May 2023

Wie gestalten sich Genderprozesse in Kinderkrippen, also in der Arbeit mit Kindern in den ersten drei Jahren? Während zu geschlechtsbezogenen Themen in frühpädagogischen Kontexten mit über dreijährigen Kindern etliche Untersuchungen vorliegen, ist Gender in Krippen ein Forschungsfeld, das bisher wenig bearbeitet wurde. Das Buch bietet einen Einblick, wie unterschiedlich Geschlecht in den alltäglichen Interaktionen zwischen Kindern, Eltern und Fachkräften relevant gemacht wird, wie sich Verknüpfungen zu weiteren Differenzlinien darstellen und welche Bedeutung die Materialausstattung hat. Es werden Perspektiven für eine genderreflektierte Pädagogik und Forschung diskutiert.
What connects entangled photons?
Authors: Muchowski Eugen
Published: May 2023

Entangled quantum systems can connect to the environment via a Bell state measurement. This applies, for example, to teleportation and entanglement swapping. Although the results are well understood, it is not entirely clear whether they involve nonlocal action or whether they are predetermined. This can best be decided from a model, provided it predicts the key measurement results. Models based on the fact that the partners of an entangled pair have the same value of a statistical parameter cannot be applied here. This is because the partner particles of the resulting entangled states after a teleportation or an entanglement swapping never had contact before. The question then is, what connects entangled photons? Therefore, this paper presents a local realistic model that reproduces the quantum mechanical predictions for expectation values with polarization measurements, but is not based on shared statistical parameters. Instead, the coupling of the entangled particles is based on initial conditions and conservation of spin angular momentum. The model refutes Bell's theorem and also explains teleportation and entanglement swapping in a local way. The manuscript is thus a step forward toward a complete theory describing quantum physical reality as thought possible by Einstein, Podolsky, and Rosen.

Effect of ammonium sulfate and phosphogypsum application on nutrients dynamics and acidity of black soil
Authors: Захарченко Еліна , Тунгуз Весна
Published: May 2023

The problem of phosphogypsum accumulation in dumps of chemical plants has been an urgent problem for several decades. The ecological situation is aggravated by the fact that more and more areas are allocated for its conservation. A negative point in the application of phosphogypsum is the intake of radionuclides and fluorine into the soil and plants, small particles could be dispersed to the atmosphere by wind. But given the presence of  macro-, mezo- and microelements in it and the high price of mineral fertilizers, it is now considered as a good fertilizer and ameliorants, especially for alkaline soils. The goal of the research was to study the effectiveness of phosphogypsum application (from Sumykhimprom) and ammonium sulfate in increasing doses of nitrogen 50‒150 on the dynamics of nitrogen, phosphorus, potassium, calcium and hydrolytic acidity of typical middle loam black soil. An increase in nitrogen led to growing the content of hydrolyzed, nitrate and ammonium forms of nitrogen in the soil. The maximum availability of N-NO3 in the soil is characteristic for the first period of sampling, in the tillering stage. At this period, the maximum difference is observed between the control and fertilized variants of the experiment. The application of phosphogypsum with N150 almost threefold increased the content of nitrates in the soil. Variants with lower doses of nitrogen also affect the accumulation of nitrates in layers 0‒20 and 20‒40 cm. After harvesting, an insignificant difference was found between the control and fertilized variants (except for N150) with a general decrease in the level of nitrate availability to 0.1‒0.2 mg/100 gm of soil. The impact of fertilizers was less on the content of labile phosphorus and exchangeable potassium. A year after fertilization, a significant increase in the value of hydrolytic acidity is observed in the fertilized variants.

It is especially noticeable at a dosage with nitrogen of 120‒125. In these variants, the hydrolytic acidity in both the arable and subsoil layers exceeds 4 mmol+/100 gm of soil. Changes in the content of water-soluble calcium are insignificant which can be explained by the fact that the solubility of calcium sulfate is not high enough and it takes more time for calcium to appear in an ionic form.

Authors:   Kyiv National University of Technologies and Design, Bondarenko Svitlana
Published: May 2023

The article discusses approaches to assessing the quality of business processes of a shoe manufacturing enterprise. To assess the quality of business processes, first of all, business processes are identified. Marketing activity, supply of basic and auxiliary materials, technological preparation, production, sales of finished products, personnel management, financial management, environmental management, information and digital management were chosen as key processes at the shoe manufacturing enterprise by a group of experts. The quality indicators of each business process are determined, which can be classified according to the following groups: indicators of functional suitability, costs, time, efficiency and effectiveness, impact on the environment, flexibility. The system of the above indicators is called a business process panel. The following methods are used to determine the value of business process quality indicators: organoleptic, measurement, registration, calculation, sociological, expert, statistical, etc. The direction of optimization is determined using logical thinking. Normalization of indicators is carried out – the transformation of all dimensional indicators into dimensionless quality indicators (desirability functions), which range from 0 (very poor quality) to 1 (very good). At the same time, the desirability scale of E. Harrington is used. Unit, сomplex and integral indicators of the quality of business processes of the enterprise are calculated according to the proposed formulas. The final stages of assessing the quality of business processes are the analysis of the obtained results and their improvement. In the practical activity of enterprises, two approaches to improving business processes are distinguished: breakthrough, fast, radical improvement, which is called reengineering, and small permanent improvements in small steps, changes for the better – kaizen. The Kaizen approach has the following frameworks, the use of which is appropriate in a shoe company: lean manufacturing, six sigma, lean manufacturing plus six sigma, kanban, Scram technologies, TRM and the 5S system.

In the article it is considered the peculiarities of the technical and economic evaluation of the innovations in the construction. In the modern conditions, the decision of providing the innovations in the construction procces should be based on the classical assessment of the technical solutions and the effectiveness of the construction projects. Using of the wide range of the modern research tools strengthens the assessment capabilities and creates new approaches to the selection of the innovations. The purpose of the article is to define the modern approaches to the evaluation of the innovative solutions in construction and the possibilities of using design-thinking tools in the determining perspective innovations. Understanding the value of the innovation for the consumer, preliminary evaluation of the innovation from the position of satisfying the consumer's needs and the involvement of consumers in the determination of promising innovative products determine the basis of the transformation of approaches to the evaluation. Innovations in construction take place in several main directions. Innovations in production include the introduction of the latest materials, energy-saving production technologies; using of drones, "smart" security devices, information monitoring of buildings (BIM), 3D printing, modern tools of the mechanization. Innovative construction facilities involve the introduction of the concept of "smart buildings", increasing the safety of the construction facilities, improvement of the energy efficiency and energy-saving technologies. Innovations in the design of construction objects include modeling of construction objects (VIM technologies), 3D printing, augmented reality in the design, creation of virtual models – "twins" of objects, and also introduction of other digital products. Innovations in the organization of construction enterprises are the introduction of the newest business models. A wide range of innovations involves the choosing not only from the company's point of view, but also taking into account the needs of consumers. Consumers' vision turns the innovative solutions to the basis of the new approach to determining their feasibility. The effective approach to solve this problem is to apply the design thinking with the wide range of tools that can be offered. Design thinking has the significant potential for the evaluating innovative solutions in construction. Involvement of the consumer in the formation of the value of the innovation at all stages of implementation using the principles of design thinking significantly increases the efficiency of the innovative activity of the construction enterprises.
