Published: April 2023

Rocky Mountain spotted fever is a tick-borne rickettsiosis. The main clinical signs and symptoms are fever, severe headache, rashes and myalgia. It is considered difficult to diagnose and underreported. The study aims to descriptively analyze the epidemiology of cases of Rocky Mountain spotted fever in Brazil from 2010 to 2021. This is a retrospective cohort study that statisticall analyzes the cases of spotted fever in Brazil between 2010 and 2020 through data obtained by the Information System of Notifiable Diseases. The proportions of spotted fever cases were calculated according to: sex, age, race/color, infection environment and evolution. There are 1967 cases were confirmed. The regions with the most cases were the Southeast (n%=72.24) and the South (n%=24). However, there are 4 deaths in the south while the lethality coefficient from the southeast is 47.78%. The most affected age group was 40-59 years old (n%=34.87), and 20-39 years old (n%=28.98). 71.17% of the cases are male. As for color/race, 60% of the cases are in whites. As for the infection environment, 35.23% are at home, 15.3% are at work, 26.13% are leisure places. The prevalence in males and the predominant age group 20-59 years can be linked to work activity, which leaves hem more exposed to ticks. The high numbers in adulthood can also be related to ecotourism. The lethality of the disease differs between the South and Southeast regions. One explanation for this phenomenon would be the different etiological agents, R. rickettsi, predominant in the Southeast, generating more severe clinical conditions.
Vacuum Arcs on Solar Array Surfaces
Authors: Vayner Boris , Ferguson Dale
Published: April 2023

Arcs on the solar arrays appear to be the most plausible source for the electromagnetic radiation observed with the Arecibo radio telescope. In the laboratory, electrostatic discharges (arcs) on solar array coupons were studied in a simulated geosynchronous equatorial orbit environment. Arc current pulses were recorded with a high time resolution (up to 0.2 ns). Spectral properties of these pulses demonstrated no monotonic behavior but rather separated peaks within the frequency range of 100–1000 MHz. Electromagnetic radiation from these arcs was registered and recorded with a Yagi antenna 8 m distant from the arc site, and a high-speed oscilloscope. Analysis of the spectra resulted in the discovery of well-separated “lines.” Evaluation of arc current spectra and radio-frequency spectra revealed statistically significant patterns in the frequency domain. Measured radio fluxes and theoretical estimates of the power of electromagnetic radiation from arcs on spacecraft solar arrays strongly argue in favor of the arcing hypothesis for the source of this radiation. These results have enabled considerable progress to be made in understanding the physical nature of the generation of electromagnetic radiation by transient vacuum discharges.
Analytical Uncertainty Propagation and Robust Trajectory Optimization for Continuous-Thrust Relative Motion
Authors: Lin Xin , Zhang Gang , Ma Huidong
Published: April 2023

Analytical continuous-thrust uncertainty propagation is derived under the control error and the initial navigation error for the linear relative motion near elliptic orbits. Two continuous-thrust control error models are considered: control-linear error model and thrust-magnitude-direction error model. The analytical uncertainty propagation expression is obtained by using the thrust series expansion with respect to eccentric anomaly. Based on the derived analytical uncertainty propagation, the robust energy-optimum and fuel-optimum orbital rendezvous problems are formulated as nonlinear programming ones. In particular, the robust energy-optimum rendezvous problem under the control-linear error model is converted into solving a one-dimensional equation. Several numerical examples indicate that the derived analytical uncertainty propagation is accurate and that the developed robust trajectory optimization approach is computationally efficient.
Three-Dimensional Optimal Homing Guidance Without Terminal Maneuverability Advantage
Authors: Li Hongyan , Tao Hong , Wang Jiang , He Shaoming
Published: April 2023

This paper investigates the three-dimensional (3-D) homing guidance problem of intercepting an evasive target with maneuverability comparable to the missile. The guidance problem is first reformulated in the relative frame to help geometrically derive the necessary condition of interception without terminal maneuverability advantage in the 3-D space. A two-stage optimal guidance law is then analytically derived with bounded acceleration to satisfy the aforementioned necessary condition. Theoretical analysis is performed to interpret the working principle and physical meaning of the proposed law. The key feature of the proposed approach lies in its fast convergence rate and low acceleration requirement. Hence, in comparison with the existing optimal approaches, the proposed law can significantly improve the operational margin and decrease the risk of command saturation in the endgame. Extensive simulations are performed to support our findings.

Published: April 2023

We present ReactionMechanismSimulator.jl (RMS), a modern differentiable software for simulation and analysis of chemical kinetic mechanisms including multi-phase systems. RMS has already been applied to problems in combustion, pyrolysis, polymers, pharmaceuticals, catalysis, and electrocatalysis. RMS is written in Julia, making it much easier to develop and allowing it to take advantage of Julia’s extensive numerical computing ecosystem. In addition to its extensive library of optimized analytic Jacobians, RMS can generate and use Jacobians computed using automatic differentiation and symbolically generated analytic Jacobians. RMS is demonstrated to be faster than Cantera and Chemkin in several benchmarks. RMS also implements an extensive set of features for analyzing chemical mechanisms, including a library of easy to call plotting functions, molecular structure resolved flux diagram generation, crash analysis, traditional sensitivity analysis, transitory sensitivity analysis and an automatic mechanism analysis toolkit. RMS implements efficient adjoint and parallel forward sensitivity analyses. We also demonstrate the ease of adding new features to RMS.
Vulnerability assessment of drinking groundwater of buchak-kaniv aquifer under the conditions of quality composition long-term transformation
Authors: Levoniuk Serhii , Udalov Ihor
Published: April 2023

Problems Statement and Purpose. This article is a continuation of the authors' previous publications on improving the methodical approach to assessing the vulnerability (protection) of drinking groundwater within the Dnipro-Donetsk artesian basin (DDAB) and is a practical component of these studies. In order to find and develop optimal forms of ecological safety management of drinking water supply for the region population, the authors' improved approach to assessing the vulnerability (protection) of drinking groundwater in the strategically important waters of buchak-kaniv aquifer (BKA) was tested. The purpose of article is the ecological and hydrogeological zoning of research area according to the danger of quality transformation of BKA groundwaters and the determination of zones of increased ecological danger of these waters quality reduction due to elements of surface and deep genesis. Data & Methods. The research is based on the analysis of results of drilling more than 950 wells in this region, as well as about 500 measurements of piezometric levels of BKA and the first interlayer aquifer during 1960-2020. Results. Complex systems of ecological and hydrogeological zoning of the territory of DDAB central part have been developed according to the degree of ecological danger of lowering the quality of BKA drinking groundwater. Zoning of the territory was carried out according to the danger of deterioration of these waters quality by man-made pollutants that enter the waters in the process of downward vertical filtration and migration from the earth surface. Ecologically dangerous areas with a potential decrease in the quality of BKA drinking groundwater due to elements of surface genesis (water intakes of Poltava, Lubny, Myrhorod, Velyka Bagachka, Krasnograd cities and some others) have been identified. Zoning of the territory was carried out according to the danger of deterioration of the BKA groundwater quality due to the upward migration of natural deep substandard waters. Ecologically dangerous areas with a potential decrease in groundwater quality due to elements of deep genesis (water intakes of Poltava, Romodan, Myrhorod, Shyshaky, Opishnia, Gadyach, Krasnograd, Karlivka cities and some others) have been identified. It is recommended to develop measures to increase the ecological safety of the population's drinking water supply: hydrogeochemical monitoring of characteristic indicators of water quality composition and optimization of the powerful water intakes operating modes (within ecologically dangerous territories); creation of new water intakes (within ecologically safe territories).
Nature of current and assessment of possible future changes in the water regime of lake Lebedyne (Sumy region)
Authors: Grebin Vasiliy , Lukіanets Olga
Published: April 2023

Aim of the research is to identify the characteristic features of modern and predictive assessment until 2030 possible changes in the water regime of the Lake Lebedyne.

Methods of the research – water balance method (to clarify the nature of modern changes in the water exchange of the lake), pairwise and multiple correlation methods (for statistical analysis of relationships between hydro-meteorological variables).

Scientific novelty – for the first time the analysis of modern changes in the water exchange of the Lake Lebedyne by comparing the components of the lake's water balance for two periods - modern (1991-2019) with the period of the climatic norm (1961-1990); for the first time estimated for the next decade (2021-2030) changes in the water regime of Lake Lebedyne.

Practical value is determined by the fact that the main provisions of this scientific research will be used when discussing a project to improve the state of Lake Lebedyne, which was provided for by the Program of Economic and Social Development of the city of Lebedin for 2020-2021 program years.

Research results. It was revealed that the total volume of water inflow into the lake in the modern period (1991-2019) has decreased (compared to the period of the climatic norm - 1961-1990) by almost 16%. Of these, the inflow of water from the area adjacent to the lake (slope runoff) decreased by 17.8%, and the amount of atmospheric precipitation on the lake's surface by 11.7% also decreased. There is a decrease in the absolute volume of evaporation from the water surface of Lake Lebedyne due to a decrease in the volume of water inflow. However, at the same time, against the background of an increase in air temperature, the intensity of evaporation increases - its share in the water-balance ratios increased by 8.3% compared to the period of the climatic norm. Evaluating the accumulative component of the lake's water balance, it can be stated that during the period of climatic normal there was a certain accumulation of water in the lake - on average by + 22130 m3 annually. In the modern period, the volume of water in the lake was depleted - on average for the period 1991-2019 by - 81200 m3 per year. As a result, the volume of water in the lakebed in the modern period has decreased by about 40-42% compared to the period of the climatic norm. According to the forecast estimates of the values of the total water inflow into the lake Lebedyne for the period 2021-2030 it can be assumed that in comparison with the previous decade, they will grow by an average of 18%. Therefore, with a certain stabilization of the evaporation values, one can expect an insignificant, but nevertheless, replenishment of the lake with water.

Authors: Zapototskyi Sergii , Provotar Nataliia , Trusii Oksana , Zapototska Victoriia
Published: April 2023

Problem Statement. Regional socio-economic development is characterized by diversity and multifacetedness and is stipulated with different impacts of factors. Ukraine has a pronounced spatial asymmetry of socio-economic development of regions; therefore, it is an important case for study of various components of regional unevenness. In the present context of post-Maidan crisis and armed conflict, study of uneven development of agrarian potential in Ukraine is becoming increasingly important, whereas it is important to assess and monitor the agrarian potential of regions for economic and food security of the country and regions.

Research Methodology. The research focuses on assessment of the agrarian potential development of Ukraine’s regions in 2015 and 2018, rather than on an empirical comparison of the agrarian potential development of regions before and during the post-Maidan crisis and armed conflict. A hierarchical model for assessing the development of the agrarian potential of Ukraine's regions has been elaborated. Based on the factor analysis results, the individual influence of each factor on the development of the agrarian potential of regions was determined. Using the method of ranking and Kohonen Self-Organizing Mapping, the changes in the uneven development of the agrarian potential of Ukraine’s regions during the post-Maidan crisis and armed conflict period were investigated, and the trajectories of the development of this potential were revealed.

This paper aims to identify the regional patterns of agrarian potential development and determine the factors that influenced its regional unevenness during the post-Maidan crisis and armed conflict.

Results. The research results prove a spatial asymmetry and an increase in regional divergence in the agrarian potential development. The impact of socio-economic and production factors was revealed to grow and the impact of natural resources and macroeconomic factors on the agrarian potential development of the regions was revealed to weaken. The trajectories of agrarian potential development of the regions are determined; they are typified in nine types of trajectories of the agrarian potential development of the regions of Ukraine during the post-Maidan crisis and armed conflict. Recommendations are given on the regional policy in the agrarian sector of Ukraine in order to mitigate the uneven development of agrarian potential in the regions. Given that Ukraine is facing the problem of inconsistency of the institutional environment with the needs of agropotential development, it is very important to implement the institutional transformations, which should focus on harmonization of state and regional policy for the agrarian sector with EU principles.

Published: April 2023

The main purpose. The purpose of this research is to develop a method for determining the level of heavy metal contamination in the soil. For this end, the following tasks are set:

- to develop a method for the integrated assessment of heavy metal contamination in the soil at the regional and local levels;

- to identify the most heavy metal contaminated regions of Ukraine;

- to estimate the level of hazard of heavy metal contamination in the soil for territories with different types of land use;

- to assess the pollution of soils with heavy metals as a result of hostilities in Donetsk and Luhansk regions.

Methodology. The method takes into account the soil morphology, genezises, trace metals background concentrations and based on the development of the self-purification index for various soils in different regions of Ukraine. According to the proposed method soils have been classified by trace metals contamination.

Results. At the local level, trace metals in soils were assessed for urban recreational areas, highways and roads, landfills and industrial zones. The soils in recreational areas were classified as ‘good’, highways and roads are classified as ‘satisfactory’ and ‘poor’, industrial and landfill was classified as ‘very poor’ according to the trace metals contamination. At the regional level, the highest contamination Class was given to the soils of Donetsk and Luhansk regions due to the highest density of industrial areas and performed military activities. The environmental assessment of trace metals contamination in soils due to the military activity was performed for these regions. The results of trace metals determination in Kharkiv according to this method indicate that the most dangerous areas are domestic waste landfills and facilities of the industrial companies. Recreation zones are ranked in Class 2. and the territory near the highways are assessed in quality Class 2 and 3. Assessment of the hazard level of trace metal contamination in the soil by the proposed method will allow making a scientifically substantiated decision on the priority of implementation of environmental measures.

Scientific novelty. The paper presents a new method of assessing soil contamination with heavy metals at the regional and local level. The advantage of this method is taking into account the hazard class of pollutants and the self-cleaning index. A new classification of the level of danger of soil contamination with heavy metals has been developed.

Practical significance. The use of the proposed methodological approach will contribute to obtaining comparable data when assessing the level of soil contamination by heavy metals and determining the priority of implementing environmental protection measures and increasing the level of environmental safety, which is especially relevant for the post-war recovery of our country.
Student Satisfaction with Online Learning: A Multigroup Analysis
Authors: Santosa Paulus Insap
Published: April 2023

The Coronavirus disease 2019 pandemic “forced” students to attend online classes roughly from mid-March 2020. This situation, which caused universities, among other institutions, to deal with an overnight change in course delivery from traditional face-to-face to online mode, has resulted in many students facing difficulties. They must cope with the available infrastructure, unstable and limited Internet connection, course delivery, and their self-discipline. Male and female students may have different preferences regarding technology use. This study focused on student satisfaction with the above situation and determined whether a difference exists between male and female students using Technology Acceptance Model as the main theoretical background. Seven hypotheses were proposed and tested with the whole dataset and comparisons between the two groups. Due to the strict health protocol, an online survey was employed using Google Form to collect data. Respondents were 327 undergraduate students from one higher institution in Yogyakarta, comprising 140 male and 187 female students. The population consisted of undergraduate students who have been attending online classes since March 2022. A multigroup analysis was performed using SmartPLS 3.3.3. Results indicated no gender difference in all hypothesized relationships. The theoretical contribution can be seen from the use of Internet Quality, User Interface Quality, and Delivery Quality as the three exogenous variables of the proposed model. The practical contribution is that technology designers must pay attention to the different preferences of user groups.

Published: April 2023

Consuming halal food is mandatory for Muslims, but meeting the growing demand for halal products has been a challenge for Muslim producers. Importing halal products from non-Muslim countries can raise doubts about their halal status. Therefore, a traceability system is needed to ensure the halalness of products. This research proposes a new traceability system by utilizing ERP, Blockchain, and smart contract technologies based on HAS 23000. This study is the first to combine these technologies. Using the System Development Life Cycle (SDLC) method, the design diagram has been successfully developed into an application system prototype. The use of ERP can help companies reduce operational costs, while the combination with blockchain technology ensures more transparent information, data protection, and system security. The system also uses smart contracts to make automated decisions. By managing the procurement of halal products, companies can ensure that products with halal assurance reach consumers.

Meat can be determined as a muscle that has entered a rigour mortis state. Due to its high
nutritional content, the quality of chicken meat quickly decreased. The changes in meat
colour, pH, and metabolite gas production, especially ammonia and hydrogen sulfide, are
the typical indicators for meat degradation. This research aimed to design and build an
apparatus to evaluate the freshness of the chicken meat displayed for sale or storage. In the
following study, four different sensors, including TCS 3200 colour sensor, Metal Oxide
Semiconductor (MOS) gas sensors (MQ 136, MQ 137), and PH-98108 sensors, were
assembled with the aid of a microcontroller and personal computer to become a meat
freshness detection apparatus. After being calibrated, the apparatus was then used to
evaluate the freshness of the chicken meat sample. The results indicated that the apparatus
showed satisfactory performance in detecting the freshness of the chicken meat sample.
This apparatus was movable, simple, cheap, easy to operate, and suitable to be used by
meat sellers or related institutions. The sensors used were capable of detecting the changes
in colour, pH, NH3 gas, and H2S of the sample. The parameters of L*, b*, pH, H2S, and
NH3 gas effectively detected the freshness of chicken meat. After 12 hrs of storage, the
values of L*, b*, pH, H2S, and NH3 gas of the sample were 50.34, 17.26, 6.59, 134.08
ppm, and 42.34 ppm, respectively.

Gluten-free mung bean biscuits have been made of mung bean flour, tapioca flour, corn
starch, and egg whites. This research aimed to determine the differences amongst varied
mung bean biscuit compositions and their influence on the acceptability, the measured
expiration period, and the content of water and fibre. This research was conducted through
a random group experiment design. Different compositions of ingredients were used, i.e.,
60% mung bean flour, 15.0 - 22.5% tapioca flour, 17.5 - 25% corn starch and 7% - 10%
egg whites. The packaging was made of plastics with a permeability of 0.0265 g/
m
2
.day.mmHg was used. The packed biscuits were put into a jar. In the analysing process,
the food acceptability was measured using a hedonic test. A further data analysis using
ANOVA followed by a Duncan test was conducted to justify the acceptability of the
prepared biscuits with different ingredient compositions. The expiration of the food was
tested using an ASLT method. The content of water and fibre was determined using an
oven method and a gravimetric analysis. This study showed that the biscuits’ acceptability
was in the range of 6.6–7.1 (out of 9) or the favourable scale. All the prepared biscuits
showed no significant difference in the physical appearance, with slight golden yellow (p
= 0.008) and the overall quality (p = 0.039). The expiration period of the gluten-free
biscuits with the F5 code (20% tapioca, 20% corn starch and 7% egg whites) was 8.66
months. The water content of all prepared biscuits was very low, in the range of 0.7-
2.36%, while the fibre content was very high in the range of 18.6–23.6 g.

Published: April 2023

Protein from fish is known as the precursor of biologically active peptides that exert
various health benefits such as antihypertensive, antitumor, and immunomodulatory
properties. Hence, this study aimed to perform an extraction of anchovy, LC-MS/MS
analysis and in silico evaluation of the major proteins in anchovies as potential precursors
of biologically active peptides in addition to determining whether such peptides can be
released by selected proteolytic enzymes. Anchovy was subjected to protein extraction
followed by total soluble protein concentration determination using Bradford assay. The
sample was subjected to in-solution trypsin digestion, which was then analysed by liquid
chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). A bioinformatic
approach by PEAKS Studio was used to identify the protein. A total of four anchovy’s
proteins which are myosin light chain 1, V(D)J recombination-activating protein, 60 kDa
chaperonin and heat shock protein 90AA1 were identified. Then, the identified proteins
were subjected to in silico approach using the BIOPEP database. The biological potential
of the theoretically released angiotensin-I converting enzyme (ACE) inhibitory peptides
and dipeptidyl peptidase (DPP)-IV inhibitory peptides were predicted by determining the
frequency of occurrence of fragments with a given activity. 60 kDa chaperonin and heat
shock protein 90AA1 predicted the highest number of biological activities for ACE
inhibitory peptides (284 and 264 fragments) and DPP-IV inhibitory peptides (395 and 409
fragments). The most promising enzyme for the generation of bioactive peptides from
anchovy protein was anticipated to be pepsin (pH > 2), which theoretically released a high
number of DPP-IV inhibitory peptides and ACE inhibitory peptides through the action of
in silico proteolysis. Overall, this work highlighted that anchovy protein could be a
promising precursor of bioactive peptides that have ACE and DPP-IV inhibitory activities
for developing functional food or nutraceutical products.

Published: April 2023

There has been increasing demand for resistant starch-enriched food products with a low
glycaemic index (GI) as consumers nowadays are aware to improve health status.
Therefore, the present study was carried out to investigate the effect of different
substitution levels of type-2 resistant starch (high-amylose maize starch) (HM) into wheat
flour. In this study, wheat flour sample (control) and six test composite flour samples
comprising wheat flour substituted with 5%, 10%, 15%, 20%, 25% and 30% of HM
powder were analyzed to compare their physicochemical characteristics, functional
properties, in vitro starch digestibility and expected glycaemic index (eGI). The results
revealed that the incorporation of HM had resulted in increased moisture (12.70 –
13.31%) and total dietary fibre (TDF) (0.19 – 0.46%), as well as a decreased proportion of
ash, fat, and protein. The carbohydrate and energy values were not significantly different
upon the increasing percentage of HM (p>0.05). Mineral analysis showed that HM
composite flour had significantly lower Mg, Ca, K, P, Fe, Zn and Se than the control. HM
composite flour exhibited greater water holding, water holding capacity, oil holding
capacity and swelling power than the control sample. The hydrolysis index and eGI of
HM composite flour decreased with higher HM substitution. In conclusion, HM
composite flours showed a good potential to be used in functional food, where positive
impacts have been observed for in vitro starch digestibility and eGI characteristic.

Wayang beber merupakan salah satu genre wayang yang telah lama ada di Indonesia. Dibandingkan
dengan genre wayang yang lain, wayang ini tergolong kurang berkembang. Sebagian besar
literatur wayang beber membahas wayang beber Remeng Mangunjaya dan Jaka Kembang Kuning.
Wayang beber masih memungkinkan dikembangkan dengan mengalihwahanakan cerita atau
folklor lokal yang berkembang, salah satunya folklor Arya Kamandaka atau Lutung Kasarung.
Tulisan ini bertujuan untuk menunjukkan proses alih wahana dari buku cerita Lutung Kasarung
ke dalam wayang beber priangan dengan lakon Arya Kamandaka. Untuk mewujudkan ini,
pengkarya menggunakan teori alih wahana dan teori ruang waktu datar (RWD). Teori alih
wahana diterapkan untuk mengalihwahanakan cerita dari (wahana) buku ke dalam (wahana)
wayang. Teori ruang waktu datar (RWD) diterapkan dalam mewujudkan cerita ke dalam bentuk
wayang beber. Berdasarkan kedua teori ini telah berhasil dibuat wayang beber yang menceritakan
kisah Arya Kamandaka kedalam tiga gulungan, setiap gulungan terdiri atas 4 sekuen. Cerita yang
ditampilkan dalam wayang beber ini terlalu datar, kurang ada konflik, sehingga kurang menarik
untuk dipertunjukkan. Penelitian ini menyarankan untuk dilakukan penelitian lanjutan untuk
memperbaiki kelemahan-kelemahan ini.

ARTIFICIAL NEURAL NETWORK TRAINING BASED ON PERFORMANCE AND RISKS ASSESSMENT DATA OF THE INVESTMENT IN DIGITAL ASSETS
Authors: Bebeshko Bohdan
Published: April 2023

The problem of analyzing the results of training artificial neural networks based on data about the efficiency and risks of investing in digital assets, particularly in the context of managing the buying and selling process of cryptocurrencies, has been investigated. The approach for solving this problem is based on the application of game theory as the main principle for forming the architecture of the artificial neural network. Combining two fundamental theories - game theory and neural networks - allows the creation of intuitively understandable and effective intelligent information systems for decision support in various application areas, such as finance, economics, and resource management. Special attention is paid to considering fuzzy parameters and uncertainties in market conditions, reflecting the real circumstances of investing in cryptocurrencies and other digital assets. The article proposes a series of methods for training and adapting the artificial neural network within the developed approach, as well as recommendations for evaluating its effectiveness and stability. The possible areas of application and prospects for further development of this methodology in the context of the digital asset market have been analyzed. The application of the developed methodology for analyzing the results of artificial neural network training has been illustrated, and its high efficiency in predicting investment performance and risks in digital assets has been confirmed. The issues and limitations that may arise during the use of this methodology were highlighted, and possible ways to overcome and improve them have been proposed..

The improvement of protection systems is based on the introduction and use of a mathematical apparatus. Ensuring the confidentiality, integrity and availability of information is an urgent and important problem in the modern world. Crisis processes are characteristic phenomena in security systems, so stochastic models cannot always describe their functioning and give a solution. An effective tool for solving this problem can be the use of dynamic models based on the provisions of catastrophe theory. This study is devoted to the analysis of modern approaches to the use of the basic provisions of catastrophe theory in cybersecurity systems. The work presents a brief historical view of the development of this theory and highlights the main definitions: bifurcations, attractors, catastrophes. Elementary catastrophes, their forms and features are characterized. A review of the literary sources of the use of catastrophe theory in information and cyber security was carried out. The analysis made it possible to single out that this theory has not yet been widely implemented, but there are point scientific developments in the process of detecting network anomalies in the cloud environment. The considered approaches to the application of catastrophe theory in information and cyber security can be used to train specialists in the specialty 125 Cybersecurity in the process of research
LIGHTING DESIGN SCHEMES AND COLOURS IN DANCE PERFORMANCES: THE MAGICAL ILLUSION
Authors: Basa Murali
Published: April 2023

Dance is a creative expression of movements, patterns, and stories they perform. The lighting design contributes to a complete theatrical experience for the audience by highlighting and framing every movement in each dance piece at the right moment. In solos and duets, lighting can emphasize this intimacy by using different spotlights in a particular area and it can make the rest of the stage dark. Different lighting fixtures will help by adding texture to the dance performances. The ambient lighting helps to set the scene, often shadow lighting, and backlighting produces striking images to elevate the body lines and also emphasize the shapes and angles. Few dance groups perform with the integrity of new technologies and Body.This article aims to attempt a definitive and comprehensive illustration of how light design plays an important role in contemporary performances. The lighting design as an art form within the theater is certainly a creative process that illuminates the performer's body to create a visual bonanza experienced by the spectator. In contemporary dance performances, it became an essential illustrative medium rather than decorative elements like in some traditional dance performances.Lighting design is a scenic art in contemporary dance performances concerned with atmosphere and 'body form' in relation to the performance space. The lighting design for a performance with a style and colour on a performer's body creates the magical illusion that is being experienced by the audience. Combinations of lighting design styles and body pigment are crucial and Indian contemporary dance groups adopted such technologies and make some interesting performances.This study analyzes how lighting design influences dance works as a creative approach to performance-making. Blending of costume, makeup, set, interactive media, and lighting design is an added advantage that we can observe in these Indian contemporary Performances. This paper analyzes how lighting design and dance are an integral part of a colorful performance.

Este estudo brota do desejo catequético de conhecer a Pastoral e a Comunicação no cenário da Igreja Católica. A partir daí a metodologia utilizada, que foi construída por meio da análise documental de textos acerca da Comunicação, da Pastoral e da maioria das Obras da Igreja Católica; partindo assim, para experiência empírica. É a práxis teológica no nosso cenário de atuação, com uma revisão bibliográfica de artigos e teses. Como resultado, tem-se um aparato que pode ser continuado posteriormente. Tudo isso gerou debates e pesquisas sobre a eficácia desses meios midiáticos na estrutura Católica, por isso, como objetivo geral, buscar-se-á compreender melhor o fenômeno observado e pesquisado: a aplicabilidade e práxis pastoral do Concílio Vaticano II pelo Inter Mirifica. Para tanto, foi necessário um processo gradual com a contextualização, por meio de um itinerário cronológico, a diferenciação do aspecto da Pastoral, da Comunicação e a da aplicabilidade comunicacional na conjuntura eclesiástica, para que ambas atuem na obra da evangelização da Igreja.
