Methods of Practising Christian Philosophy
Authors: Mbamara Sabastine Kingsley
Published: June 2022

The concept of Christian Philosophy is not new in the history of philosophy. However, since the mid-twentieth century the idea of Christian Philosophy gained momentum and has become an object of explicit discussion among philosophers. The historical circumstances leading to its emergence as a distinct type of philosophy are not here discussed, and the existence of Christian Philosophy with a distinct content and purpose that sets it apart from other philosophies is here presupposed. Instead, the paper focuses on the concept and methods of practising Christian Philosophy with specific reference to the methodology developed by Stanisław Kamiński (1919–1986). The paper argues for the suitability of his method of philosophising within the context of Christian Philosophy. Kamiński proposes a unique style that is strictly philosophical but also Christian. This methodology was based on the classical theory of being which fulfils the demand for the autonomy of philosophy but in relationship to faith. Kamiński’s doctrinal standpoints in philosophy are rational, objective, and universal. But is also most friendly and compatible with the Christian faith. In this sense, one can speak of his Christian philosophy and the suitability of his methodology for the practice of Christian philosophy.

Published: June 2022

Introduction. With the integration of higher education in Ukraine into the world educational process and the strengthening of the role of global economic processes, there is an urgent need to train highly qualified professionals who are competitive in the labour market regardless of the European Union. The initial stage of this process is the formation of the world of competencies needed by applicants in further education and professional activities. To effectively analyse the impact of academic disciplines on the formation of competencies, it is necessary to use mathematical modelling, in particular, it will be appropriate to use cognitive models that can solve predictive problems in conditions of uncertainty.
Goal. The purpose of the article is to create a cognitive model of the educational process of higher education to provide conditions for the implementation of an effective curriculum for the formation of the necessary competencies.
Method (methodology). The main methods used in the research process: cognitive modelling (construction of cognitive maps to determine the indirect impact of disciplines on the set of competencies), expert method (for the formation of subject connections) and mathematical apparatus (activation functions Cosco and sigmoids for reflection of uncertainty, dynamics states of concepts and connections between them).
Results. The article forms a list of concepts and relevant relationships based on qualitative methods of analysis and builds a mathematical model of cognitive maps of the educational process. An analysis of the impact of different subjects on the formation of "hard skills" and "soft skills". Different scenarios of changes in the curriculum and their impact on the formation of relevant competencies are analysed.
Conclusions. Based on the main provisions on the prospects for the development of the range of skills that a graduate of 2030 should have, which are highlighted in the National Economic Strategy until 2030 and the World Economic Forum report proposes to increase attention and increase teaching hours in three main disciplines: mathematics, computer science and foreign language. These disciplines are fundamental to many, both "hard skills" and "soft skills" due to indirect links with other disciplines. Only due to this, Ukrainian graduates will have a high competitive position in the labour market.

Published: June 2022

Introduction. Today's new challenges dictate changes in the guidelines of development in the field of environmental insurance. Environmental issues are extremely important factors in such changes. In addition, they are exacerbated daily by the effects of the full-scale Russian-Ukrainian war, which continues to this day. It is obvious that the strategic directions, which were outlined long before its beginning, have lost their significance and to some extent have identified a new range of problems and their consequences. Given the outlined range of problems, environmental insurance is especially relevant, which has undergone changes that are produced by today's challenges and thus led to the definition of new strategic guidelines for their development.
Purpose. Investigate the development of environmental insurance in the range of domestic and global scale, which will determine the strategic guidelines for its development.
Method (methodology). In the process of research such methods were used as logical, which allowed to analyze scientific works in the field of environmental insurance; analysis and synthesis, which made it possible to identify factors influencing environmental insurance.
Results. The normative and legal basis for the introduction of compulsory environmental insurance is described. The focus is on the mandatory change of previously announced strategic guidelines for the development of environmental insurance to take into account military risks in Ukraine. Strategic guidelines for environmental insurance in Ukraine have been identified, which cover five sectors: electricity, oil and gas, utilities, industry and finance, which need to be ensured in the legislative sphere. It is proposed to implement attractive environmental insurance conditions for «green» insurers in Ukraine. It is established that the practical aspects of the study of strategic guidelines for the development of environmental insurance require further study in the direction of decarbonization, which may be possible after the end of the russian-Ukrainian war

Published: June 2022

Using micro-doppler signatures is an effective way to classify different types of UAVs, as well as other airborne objects such as birds. To generate signatures for drones, radar measurements are needed; however, these measurements are limited to the types of available drones, the radar parameters, the targets’ range, and the environments in which these measurements are conducted. In this paper, a new method for generating signature datasets is introduced. The method uses full-wave electromagnetic simulation software. Using this method, radar drones’ datasets can be generated using different types, sizes, drone materials, radar parameters, detected range, targets speed, and rotor RPM for rotary drones. A 77 GHz modeled FMCW radar is used to create dataset for classification purposes. Finally, a Convolutional Neural Network (CNN) algorithm is used to classify five types of drones. Based on the results, the classification of the drones is found to exceed 97% accuracy. 
MRRT: Modeling of multiple reflections of radiation between terrains applied on the lunar surface region
Authors: Liu Yunfei
Published: June 2022

The lunar surface has a stable luminosity. To use the Moon as a calibration standard, the Robotic Lunar Observatory (ROLO) program models the integration of the radiance of the entire lunar surface. However, the albedos of the mare and the highlands are very different. The modeling based on the lunar global irradiance/reflected radiance is bound to result in higher uncertainty. In contrast, if the local calibration of the lunar surface is adopted, the lunar complex topography effect cannot be ignored. This paper presents a new model for quantifying multiple reflections of radiation between terrains (MRRT). The relationship between the bidirectional reflectance factor (BRF) of the observed pixel and the true microtopography reflectance is established, which shows that the BRF is mainly influenced by the true topography reflectance, the terrain undulation, the incident irradiance on the topography surface, and the masking in the observation direction. The new model applied on the lunar surface obtains clearer terrain details. The inversion reflectance of the Chang'e-3 landing area is closer to the reflectance measured in situ, and the reflectance curves of the Apollo 16 landing area are almost consistent under different illumination observation geometries. This shows that the MRRT model can effectively eliminate the topographic effect. Compared with the ROLO model, the MRRT model does not restrict the specific selection, so it can select a region with a uniform material distribution, small albedo difference, and low topography undulation to establish the lunar surface radiometric calibration field with the advantage of providing stable radiation characteristics.
Synchronization Stability of Grid-Connected VSC with Limits of PLL
Authors: Li Yujun
Published: June 2022

Limits of phase locked loop (PLL) are necessary to make sure the transient converter frequency bounded in a safety range. This leads to the grid-connected voltage source converter (VSC) with limits of PLL as one switched system. Stability of switched dynamic system is fully discussed in this paper. One conservative analytical stable region of the unbounded autonomous system is derived by Lyapunov method. It is proved that when bounds are touched, any trajectory of the studied switched system deviates from these bounds at two fixed switching Points. Moreover, the switched system energy is non-increasing when trajectories lie inside the derived analytical stable region. Based on these properties of switched system, it is proved that to ensure the globally asymptotically stability, the fixed switching Points should be placed inside the derived stable region of the unbounded autonomous system. Finally, stabilization method is proposed via placement of the fixed switching Points so that the globally asymptotically stability is ensured.

Authors: Gupta Sandeep , Epiphaniou Gregory , Maple Carsten
Published: June 2022

A number of research in Information and Communication Technology (ICT) have shown that usability is an important goal for software-based interactive systems and products for a wider acceptance by their end-users. To evaluate the usability of a system under design, usability evaluation methods predominantly rely on subject matter experts or testers' assessments. However, integrating the Artificial Intelligence (AI) technology and existing usability evaluation methods' processes can aid to evolve more effective user-centered designs. In this paper, we conceptualize an AI-augmented usability evaluation framework (AIUEF) that aims at replacing `end-users' with `personas' to evaluate requirements involving human-computer interaction (HCI) for a given Software Requirements Specification (SRS). We present a blueprint of AIUEF that is the first step to furnishing a theoretical basis for automated usability evaluation of HCI requirements for a given SRS with an aim to improve the usability of a system under design.

Background: Hemodialysis (HD) is the most extensively used dialysis method globally, and it necessitates vascular access. Arteriovenous fistulas (AVF), arteriovenous grafts, and central venous catheters (CVC), which can be tunneled or not, are all methods for gaining access. Vascular access is a major risk factor for bacteremia, hospitalization, and mortality among HD patients. The efficacy of Actolind solution in suppressing jugular catheter infection sites in patients with positive jugular catheter culture swab was investigated, as well as the efficiency of Actolind solution opposed to iodine. Methodology: This was a prospective, randomized, comparable efficacy clinical trial completed at the renal unit of the Port Sudan teaching hospital's renal dialysis center. The patient group was recruited from across the Red Sea State. A retrospective study of 50 End Stage Renal Disease (ESRD) patients who were either on upkeep HD or were scheduled to receive a kidney transplant as soon as possible. Sociodemographics, comorbidities, and microbiological growth outcomes were gathered prior to and after the interventional procedure. Results: According to the results, the male to female ratio was 4:1. There were 39 males and 11 females. All of the patients had ESRD, with 10 of them being hypertensive and diabetic, 34 being diabetic solely, and 16 being hypertension exclusively. Gram positive bacteria, gram negative bacteria, and yeasts constituted 32 (64%), 20 (40%), and 6 (12%) of the cultivars, respectively. Seven patients out of fifty had mixed infections (14%). Forty-one wound swab results after intervention were negative, while nine patients had persistent infection confirmed by positive cultures. Conclusion: Removal of CVC due to infection or catheter malfunction occurred less often with Actolind-based lock solutions. We present the prospective comparing Actolind - and iodine -based lock solutions yet. However, due to the retrospective observational nature of this study, conclusions with regard to superiority should be considering.

Published: June 2022

Selecting team is one of the important issues in football. The role of a coach is selecting players that are formed subjectively without regard to various criteria. Her decision can impact team performance. Thus, this paper presents a new methodology to assess and rank football team based on multi-criteria decision making (MCDM). The aim is to select the best team for each football game by taking several criteria into account. The Analytic Hierarchy Process (AHP) method is used to determine the weightings for evaluation criteria among decision makers and Case-based reasoning systems to selecting the best team. We test the efficiency of the model using Paris Saint Germain champion’s league final.
Kafka Lives: Consideration of Psychological Wellbeing on Staff under Investigation Procedures in the NHS
Authors: Hussain Feryad A.
Published: June 2022

Culture change in the UK National Health Service (NHS) became a national concern following the Francis enquiry (2013) with increasing initiatives to develop models of compassionate management. This call was intended to create an environment to address investigations in the best possible manner creating a nurturing environment for staff and in turn their patients; a truly no-blame culture. Whilst principles of justice and compassionate are intended to underpin staff investigations, our clinical experience at the coal-face in working with Staff under Investigation (SUI) has proved that this is (too often) not the case. SUI often find they have little information about the complaint against them, little communication to clarify and await the outcome in general isolation from organisational or team access, until they are invited to the attend and explain their position. The resultant anxiety and distress mean that they are left traumatised by the investigation procedure itself. This brief paper aims to highlight the avoidable stressors caused by investigation procedures in the UK NHS themselves and aims to highlights aspects of these polices which require greater attention. This in turn would support a beneficial outcome for the investigation procedures overall. Whilst focusing on the UK, the generic processes of investigation have a number of commonalities which allow this information to be applicable to a range of health care services and investigation procedures.

Published: June 2022

According to the World Health Organization, approximately 70% of adults in Mexico are overweight or obese, determining factors in the development of diabetes mellitus type 2. In addition, according to the National Institute of Public Health, 10.3% of those over 20 years old suffer from diabetes. To facilitate decision or classification tasks when treating a patient, experts develop systems based on fuzzy logic, however, this design is not usually infallible, so it is common to optimize them to improve their performance. The present work shows the results of a comparison between the efficiency in predicting the risk of suffering from type 2 diabetes established by the FINDRISC test and an own design fuzzy system optimized by the Simulated Annealing heuristic for 295 patients from Acapulco, Mexico. The comparison shows that the fuzzy system obtains the same sensitivity, but higher specificity values and positive and negative predictive values with general improvement in the confidence intervals, concluding that using the proposed system as an aid in the prevention of type 2 diabetes is viable and yields results attached to the reality of the patients.

Published: June 2022

To realize the fast and accurate counting of winter wheat at the seedling stage in fields, we propose a recognition method based on an improved YOLOv4 model. Firstly, we employed a simplified MobileNetv3 neural network instead of the standard CSPDarknet53 network structure. Besides, we added an adaptive image scaling layer in front of the MobileNetv3 network. Finally, we utilized the coyote optimization algorithm (COA) to optimize the learning rate and convolution kernel size. Results showed that the average precision (AP) values of the improved network model for 2-leaf and 3-leaf winter wheat were 96.46% and 93.87%, respectively. The mean average accuracy (mAP) was 95.15% and the average recognition speed was 0.07 s. These indicators were the best, compared with the YOLOv4, YOLOv3, and Faster-RCNN models. Also, the mAP was 12.28% higher than the standard YOLOv4 model, and the average recognition speed was 1.49 times faster. Therefore, this method can achieve the fast and accurate counting of winter wheat during the seedling stage in the field.

To study the soil pH value, quality characteristics of organic matter, and available elements in intensive cultivation of walnut orchards in different areas of Hubei Province, and to provide the scientific basis for the soil management of walnut orchards in different areas，the distribution frequency and correlation of the pH value, organic matter and alkalescence N, available P, available K, available Ca, available Mg, available S,available Fe, available Zn, andavailable B in 135 walnut orchards from 6 walnut production areas in Hubei Province were analyzed by a typical sampling method. The differences and main sources of comprehensive fertility coefficients in different production areas were also analyzed. The distribution frequency of organic matter and available elements in walnut orchards were unbalanced. Available P was the most skewed with 55.67%. The soil organic matter content was significantly correlated with the contents of alkalescence N, available P, available K, available Mg, available Fe, available Zn and available B. The comprehensive soil fertility coefficient ranged from 1.21 to 1.84, with an average of 1.52, which was the general fertility level. The maximum limiting factor of soil fertility was available S, followed by alkalescence N and available P. There were significant differences in comprehensive soil fertility among different walnut production areas. 92.67% of the differences came from within the production areas, and 7.33% from between production areas. The highest differentiation coefficients were available K and available P, which were 26.20% and 10.79%, respectively. The contents of alkalescence N and P were elements that affect the soil fertility of walnut production areas in Hubei Province. And the skew amounts and differentiation coefficients of P were larger than other elements. In view of the significant positive correlation between organic matter content and most soil elements, in order to improve the comprehensive soil fertility, it is suggested that soil management should focus on increasing soil organic matter, the application of phosphorus fertilizer and improving the availability of phosphorus.

Published: June 2022

Medicinal plants abound in conventional medicines with antioxidant potentials that may be of value for the treatment of diseases, but with little or no scientific basis for their use. So, the present study aims to conduct a detailed investigation of phytochemicals present in two wild Solanum plants and also their potential use as an effective antioxidant agent. The objective of this present work was to identify the phytochemical compounds by using Gas chromatography–mass spectrometry technique and its biological activity of Solanum plant leaf extracts of methanol solvent systems were predicted using PASS online software. The methanolic leaf extract of Solanum nigrum and Solanum lycopersicum was tested to determine its chemical composition. The result of the preliminary phytochemical investigation in methanolic extract of Solanum revealed the presence of several bioactive secondary metabolites. In order to better understand the common uses of this plant, the antioxidant activity of the extracts was also measured using three separate assays.: “radical 2,2- diphenyl-1-picrylhydrazyl (DPPH) scavenging activity, Ferric-reducing antioxidant power (FRAP) and 2,2-azino-bis(3-etilbenzotiazolin)-6-sulfonic acid (ABTS) scavenging assay”. In different antioxidant assays, the methanolic extract showed different IC50 values slightly higher than the standard to confirm the importance of medicinal plant's bioactive metabolites.

Therefore, the present study optimized stocking density for pacific white shrimp reared in the pond ecosystem in Pakistan. The initial weight of postlarvae was (0.003±0.001 grams), and were stocked in 3 stocking densities (Treatment 1- 133.3 PL/m2, Treatment 2- 300 PL/m2, and Treatment 3- 466.6PL/m2) for 114 days. The water quality parameters ranged between (29.3-30.2° C), (5.1-5.5 mg/L), (5.8-7.3), (24.16-16.44 ppt.), (118-120 mg/L), (0.29-0.41 mg/L), (0.97-1.51mg/L), (0.08-0.09 mg/L), (0.02-0.12 mg/L) and (560.66-610 mg/L) for temperature, DO, pH, salinity, alkalinity, phosphate, nitrate, nitrite, ammonium nitrogen and TSS, respectively. Treatment 1 had the highest final weight (24.30±0.90 g), final length (15.8±0.30 cm), average daily gain (0.21g /day), weight gain (24.29 g) and Viscerosomatic index (4.6 g), which was significantly different compared to treatment 2 and treatment 3 (p<0.05). SGR did not differ significantly (p>0.05) between treatment 1 (7.64 % /day) and treatment 2 (7.63% /day) but was significantly higher than treatment 3 (7.10 %/ day). The Hepatosomatic index and Fulton’s condition factor were not significantly varied among the treatments. Treatment 1 had the best FCR (1.11) compared to the other treatments. The survival rate of shrimp significantly varied among these treatments (p<0.05) and treatment 1 had the highest survival rate (90.6%), followed by treatment 2 (82.20%) and treatment 3 (75.38%). Moreover, polynomial regression showed that 133.3 PL/m2 to 240 PL/m2 is an excellent stocking density for L. vannamei. Furthermore, the stoking density from 240 PL/m2 to 460 PL/m2 decreased the growth and survival rate. The present study concluded that the stocking density of L. vannamei at 250-300 PL/m2) can achieve the best growth and survival rate.

An algorithm for quadratically constrained multi-objective quadratic fractional programming with pentagonal fuzzy numbers
Authors: Goyal Vandana , Rani Namrata , Gupta Deepak
Published: June 2022

This study proposes a methodology to obtain an efficient solution for a programming model which is multi-objective quadratic fractional with pentagonal fuzzy numbers as coefficients in all the objective functions and constraints. The proposed approach consists of three stages. In the first stage, defuzzification of the coefficients is carried out using the mean method of α-cut. Then, in the second stage, a crisp multi-objective quadratic fractional programming model (MOQFP) is constructed to obtain a non-fractional model based on an iterative parametric approach. In the final stage, this multiobjective non-fractional model is transformed to obtain a model with a single objective by applying the ε-constraint method. This final model is then solved to get desired solution. Also, an algorithm and flowchart expressing the methodology are given to present a clear picture of the approach. Finally, a numerical example illustrating the complete approach is given.

Published: June 2022

The paper addresses the location-allocation and transportation problems in designing a cross-docking distribution network that consists of suppliers, cross-docks, and plants. A developed mixed-integer non-linear model is proposed for a post-distribution cross-docking strategy with multiple cross-docks and products that cross-docks can be connected. The objective function is to minimise the total cost comprising the cost of established cross-docks and transportation costs. To obtain this model, first, two models are introduced and compared (basic non-linear model 1 and non-linear model 2 with the possibility of connections between cross-docks). Results indicate that the total cost is decreased when the connection between cross-docks exists. So, model 2 is more efficient and suitable than model 1. Then, consolidation of plant orders is added to model 2, and the developed model is formulated. Finally, some problems with different sizes are generated randomly and solved by GAMS software to evaluate the model accuracy.
The glymphatic system and subarachnoid hemorrhage: disruption and recovery
Authors: Quintin Stephan , Barpujari Arnav , Mehkri Yusuf , Hernandez Jairo , Lucke-Wold Brandon
Published: June 2022

The glymphatic system, or glial-lymphatic system, is a waste clearance system composed of perivascular channels formed by astrocytes that mediate the clearance of proteins and metabolites from the brain. These channels facilitate the movement of cerebrospinal fluid throughout brain parenchyma and are critical for homeostasis. Disruption of the glymphatic system leads to an accumulation of these waste products as well as increased interstitial fluid in the brain. These phenomena are also seen during and after subarachnoid hemorrhages (SAH), contributing to the brain damage seen after rupture of a major blood vessel. Herein this review provides an overview of the glymphatic system, its disruption during SAH, and its function in recovery following SAH. The review also outlines drugs which target the glymphatic system and may have therapeutic applications following SAH.
