Authors: Borges Rosimar
Published: April 2024

A pandemia de covid-19 impactou profundamente a saúde pública e a área da educação do ensino superior, o que refletiu em inovações e desafios para as docentes do ensino superior da Universidade Federal do Rio de Janeiro. O objetivo deste estudo foi contribuir para o debate acerca dos reflexos da pandemia no trabalho e na vida das docentes da Universidade. Utilizou-se a pesquisa qualitativa e adotou-se a entrevista semiestruturada realizada com 36 docentes do sexo feminino das unidades vinculadas ao Centro de Filosofia e Ciências Humanas da instituição. As entrevistas foram realizadas e gravadas por meio da plataforma Zoom, e para a análise utilizou-se o método de interpretação de sentidos. Os resultados apontaram que no contexto pandêmico novas exigências foram postas à profissão, com a implantação do ensino remoto emergencial. Esse novo cenário provocou desgaste emocional, expresso por sensações de cansaço, impotência, sobrecarga de trabalho, adoecimento e dificuldades de relacionamento com os alunos. A pandemia apontou a sobrecarga de trabalho como fator de risco para o adoecimento das docentes da Universidade, por envolver questões como as desigualdades de gênero, conciliação das esferas pública e privada, excesso de trabalho e ausência de políticas institucionais voltadas para as mulheres no contexto pandêmico.

SPATIAL THINKING ABILITY IN ELEMENTARY SCHOOL
Authors: Herawati Herawati , Hariyani Mimi
Published: April 2024

Spatial thinking ability is the ability to mentally manipulate and rotate an object in solving two-dimensional and third-dimensional geometric problems as well as the ability to imagine the shape of an object from a different perspective in solving three-dimensional geometric problems. This spatial ability is very necessary for students because good spatial abilities will also support good understanding of mathematics. Apart from that, students also need spatial abilities to solve everyday problems, such as looking at a map, explaining their position and so on. This spatial ability consists of spatial visualization, spatial rotation and spatial orientation. To improve spatial abilities, teachers must be creative in designing learning by using various media or teaching aids that are appropriate to the material being studied.Keywords: Spatial thinking skills, Geometry, Elementary education
AL-QUR'AN THERAPY LEARNING AND UNDERSTANDING THE TRACE OF PROPHETIC TEACHING THROUGH PROPHETIC LEADERSHIP LECTURES
Authors: Ariska Ike Gustia , Budiharto Sus
Published: April 2024

Al-Qur'an therapy is a therapy using verses in the Al-Qur'an as a source of inspiration and media to help overcome spiritual, mental, physical and social problems. This includes reading, memorizing, understanding, living, and finding the relationship between the meaning of verses in the Koran and everyday problems and experiences. The discovery of meaning and wisdom allows students to feel emotional balance and improve their well-being, as well as being a medium for learning and understanding the traces of prophetic teachings in everyday life. An understanding of the traces of prophetic teachings was studied in the Prophetic Leadership Lecture at the Professional Psychology Study Program at the Masters Level at the Islamic University of Indonesia. One of the methods in this course is self-reflection on the four dimensions of prophetic leadership: Sidiq, Amanah, Tabligh, Fathanah. Based on self-reflection, several themes were found, namely finding new drugs, being grateful, feeling calm, and practicing knowledge. These findings enable students to become better individuals, to understand themselves and others, to function their minds and hearts through appreciating the values found in the Al-Qur'an.

Authors: Le Thang Ngoc , Nguyen Dung Duc , Nguyen Quang Ngoc , Nguyen Hang Thu
Published: April 2024

The paper aims to factor in the effect of tax compliance on small and medium-sized enterprises (SMEs) in Vietnam. For SMEs, tax compliance is a critical aspect of financial management. In an emerging market with a dramatically growing economy, Vietnam provides a wide range of opportunities for SMEs to thrive. The author’s 91 samples were collected from individuals specializing in accounting, auditing, and tax fields in some places in Vietnam. Efebera et al. (2004) applied an extension of the theory of planned behavior (TPB) model to demonstrate a positive relationship between equity perception, normative expectations, legal sanctions, and the intention to comply with tax regulations of individual taxpayers. We assess and analyze four factors including the perception of the utility of tax compliance, subjective norms, characteristics of tax policies, and economic environment affecting the tax compliance behavior of SMEs. The data analysis is carried out by using partial least squares structural equation modeling (PLS-SEM). The result shows that the perception of the utility of tax compliance, the characteristics of tax policies, and the economic environment have a positive and significant impact on tax compliance behavior. However, the research fails to test the influence of subjective norms on tax compliance behavior.

This publication presents the outcomes of the Connective Symposium, which took place at Fontys Academy of the Arts in Tilburg, in November 2022. The symposium was the first time that the professorship and research group Artistic Connective Practices, initiated in 2021, opened its work to the international field: We invited practitioners from all over the world to share their work and exchange about the concept of "artistic connectivity".

"Artistic Connectivity Unfolding" is an attempt to share the experiences during the symposium with the broader artistic research audience, and to contribute to the body of artistic research work that is socially engaged. The exposition is potentially many things: In part, it is a piece of documentation of the symposium, in part reflections on and proceedings of it. It is also an explorative contribution to our emerging and unfolding discourse of artistic connectivity, — unfinished, fluid and moving — and thus a springboard for our future work on artistic connectivity.
THE DETERRITORIALIZATION CULTURE OF ISLAMIC BOARDING SCHOOLS: A NETNOGRAPHY STUDY OF LIVE STREAMING USERS OF KULIAH IHYA' TEMATIK AND NGARIKSA ON FACEBOOK
Authors: Nurul Nurul Khotimah , Abdul Basit  , Tamam Mukhammad Khoiru , Putra Pandika Adi
Published: April 2024

The teaching tradition of Islamic boarding schools has encountered deterritorialization. Islamic boarding schools that used to be distinguished by traditionality have transformed the management, financial, and learning traditions following digital developments. This article aims to examine the substantial shift in Islamic boarding school intellectual traditions from traditional to digital, which will then be called 'online recitation’, through live Facebook streaming content of Kuliah Ihya' Tematik (Ihya' Thematic Lectures) and Ngariksa (Questioning). The data were collected through documentation, surveys, and in-depth interviews involving kyai, production teams, and online santri (student) of two Facebook accounts: Ulil Abshar Abdalla (Ihya' Thematic Lectures) and Oman Fathurahman (Ngariksa). Data was analyzed using netnography through investigation, interaction, immersion, integration, and incarnation stages. The results showed values, rituals, heroes, and symbols in the deterritorialization culture of Islamic boarding schools. Followers of the online recitation get a social experience (becoming more sensitive to social issues) and a ritual experience (calmness in living life) after participating in the Ngaji online through live streaming or recorded playback. Research contributes to the development of Islamic communication science where Islamic boarding schools as the oldest Islamic educational institutions in Indonesia can communicate to the wider community about learning activities in Islamic boarding schools through social media which is of great interest to the public.
Moisture conditions are limiting evapotranspiration changes of alpine mountains of Qilian Mountains
Authors: Wang Yunying , Li Zongxing
Published: April 2024

Changes in evapotranspiration and its response to control variables are
crucial for understanding water balance and climate change in
high-altitude areas. Environmental changes will inevitably disturb
regional water cycles and water balance, especially in the high-altitude
alpine regions of the Qilian Mountains. To better understand the
variation of evapotranspiration at different altitudes in the
high-altitude region of the Qilian Mountains and the applicability of
the model and its response to environmental factors, we measured the
variation of actual evapotranspiration at three altitude gradients using
meteorological stations and automatic observation of continuous data
with a weighing-type micro-lysimeter at three altitude gradients of 3797
m, 4250 m, and 4303 m in the Shaliu River basin of the Qilian Mountains
during the growing season from June 2020 to October 2022 in our
research. Using ten models to calculate the variation of reference
evapotranspiration, and fitting them to the actual evapotranspiration,
we selected the most suitable model. The results showed that the
cumulative total evapotranspiration during the growing season in our
study period was 1974.556 mm, 2203.066 mm, and 2201.393 mm,
respectively, with intra-annual fluctuations consistent across the three
elevation gradients. The value of evapotranspiration in August showed
the highest at the monthly scale of 4.809 mm·day
and a bimodal variation at the daily scale with peaks at 10:00 and
15:00. The model of Dalton simulations showed the best results with the
lowest analysis of residuals (RA), root mean square error (RMSE), and
percentage error (PE), which had values of 3.291 mm·day
, 3.994 mm·day , and 0.692%,
and the values of R between simulated and measured
values of 0.622, 0.609, and 0.420. Water balance results showed that a
portion of evapotranspiration in the study area originated from deep
soil moisture. Partial Least Squares Regression (PLSR) analysis and
enhanced regression tree model results indicated that precipitation was
the most important variable, with Variable Importance in Projection
(VIP) scores of 2.079 and a relative contribution to evapotranspiration
of 52.6%. Overall, moisture conditions and precipitation were important
factors limiting evapotranspiration variation in our research area. Our
findings have implications for future climate change conditions. This
conclusion is important for future water budget details in alpine
mountains under climate change.
Large-scale atomistic simulations of magnesium oxide exsolution driven by machine learning potentials: Implications for the early geodynamo
Authors: Deng Jie
Published: April 2024

The precipitation of magnesium oxide (MgO) from the Earth’s core has
been proposed as a potential energy source to power the geodynamo prior
to the inner core solidification. Yet, the stable phase and exact amount
of MgO exsolution remain elusive. Here we utilize an iterative learning
scheme to develop a unified deep learning interatomic potential for the
Mg-Fe-O system valid over a wide pressure-temperature range. This
potential enables direct, large-scale simulations of MgO exsolution
processes at the Earth’s core-mantle boundary. Our results suggest that
Mg exsolves in the form of crystalline Fe-poor ferropericlase as opposed
to a liquid MgO component presumed previously. The solubility of Mg in
the core is limited, and the present-day core is nearly Mg-free. The
resulting exsolution rate is small yet nonnegligible, suggesting that
MgO exsolution can provide a potentially important energy source,
although it alone may be difficult to drive an early geodynamo.
Propagation of Slow Slip Events on Rough Faults: Clustering, Back Propagation, and Re-rupturing
Authors: Sun Yudong , Cattania Camilla
Published: April 2024

Seismic and geodetic observations show that slow slip events (SSEs) in
subduction zones can happen at all temporal and spatial scales and
propagate at various velocities. Observation of rapid tremor reversals
(RTRs) indicates back-propagating fronts traveling much faster than the
main rupture front. Heterogeneity of fault properties, such as fault
roughness, is a ubiquitous feature often invoked to explain this complex
behavior, but how roughness affects SSEs is poorly understood. Here we
use quasi-dynamic seismic cycle simulations to model SSEs on a rough
fault, using normal stress perturbations as a proxy for roughness and
assuming rate-and-state friction, with strengthening behavior at high
slip rate. SSEs exhibit temporal clustering, large variations in rupture
length and propagation speed, and back-propagating fronts at different
scales. We identify a mechanism for back propagation: as ruptures
propagate through low-normal stress regions, a rapid increase in slip
velocity combined with rate-strengthening friction induces stress
oscillations at the rupture tip, and the subsequent ”delayed stress
drop’ induces secondary back-propagating fronts. Moreover, on rough
faults with fractal elevation profiles, the transition from pulse to
crack can also lead to the re-rupture of SSEs due to local variations in
the level of heterogeneity. Our study provides a possible mechanism for
the complex evolution of SSEs inferred from geophysical observations and
its link to fault roughness.
Estimation of spectral solar irradiance in the ecliptic plane using synthetic solar surface magnetograms
Authors: Oliveira Isabela de , Sowmya K , Nèmec N.-E , Shapiro A I
Published: April 2024

The primary external energy input to planetary atmospheres comes from
solar radiation. Accurate estimates of solar irradiance are needed in
order to understand atmospheric conditions at other planets. Many
studies have interpolated Earth-based irradiance measurements at other
planets, disregarding the evolution of solar features, which are
responsible for the irradiance variability. We present an approach for
assessing solar irradiance at other planets by using synthetic full
surface magnetograms of the Sun, generated by the Surface Flux Transport
Model, and then converted into sunspots and faculae areas. Following the
Spectral And Total Irradiance REconstruction approach, we compute the
irradiance as the sum of contributions from sunspots, faculae, and the
quiet Sun. We calculate the S-index, which is a proxy for
near-ultraviolet irradiance, and the total solar irradiance, which is
the wavelength-integrated value. We demonstrate that a simple phase
shift of the Earth-observed total solar irradiance does not produce
reliable estimates in the ecliptic. By comparing and correlating our
results with the interpolated measurements, we find that the two models
agree in the S-index variability, because faculae have a long lifetime,
so the effect of the solar rotation becomes less important. Conversely,
the methods disagree strongly in the total solar irradiance, since
sunspots have a short lifetime, and the interpolation does not take into
account their emergence and evolution on the far-side of the Sun, as it
only uses the information of the disc visible for an Earth-bound
observer.
Crustal structure of the Northeast South China Sea rifted margin
Authors: Vargas Mateus Rodrigues de , Tugend Julie , Mohn Geoffroy , Kuzsnir Nick , Liang-Fu Lin
Published: April 2024

We investigate the crustal structure of the NE South China Sea (SCS)
margin to constrain its crustal thickness and basement nature with
implications for the Mesozoic and Cenozoic evolution of the SCS.
First-order interfaces interpreted from seismic reflection data were
integrated into a 3D gravity inversion scheme to determine Moho depth
and crustal thickness variations. A joint inversion of seismic and
gravity data allowed us to determine crustal density variations along 2D
profiles. The distal margin is divided into two distinct crustal
domains: the Southern Rift System (SRS), and Southern High (SH). The SRS
shows an extremely thinned continental crust on top of which thick
Cenozoic sequences are observed. It is separated from the oceanic crust
(~ 6 to 8 km thick) by the SH, a comparatively thicker
crust (~ 10 to 15 km thick) with numerous magmatic
additions. The distal NE SCS margin formed during the Cenozoic rifting
of the SCS. The crust of the SH likely corresponds to a polygenic crust,
recording polyphase magmatic activity since the Mesozoic, with
potentially significant activity during Cenozoic post-rift time. The NE
SCS margin is conjugate to Palawan, whose basement is interpreted to be
part of the exotic Luconia microcontinent that collided with Eurasia
during the Late Cretaceous. Basement similarities between Palawan and
the SH are highlighted, suggesting that the latter might also be part of
Luconia. Our results suggest that the suture between Eurasia and Luconia
might have acted as a preferred zone for the Cenozoic rift development.
Vertically resolved analysis of the Madden-Julian Oscillation highlights the role of convective transport of moist static energy
Authors: Yang Da , Yao Lin , Hannah Walter
Published: April 2024

We simulate the Madden-Julian oscillation (MJO) over an aquaplanet with
uniform surface temperature using the multiscale modeling framework
(MMF) configuration of the Energy Exascale Earth System Model
(E3SM-MMF). The model produces MJO-like features that have a similar
spatial structure and propagation behavior to the observed MJO. To
explore the processes involved in the propagation and maintenance of
these MJO-like features, we perform a vertically resolved moist static
energy (MSE) analysis for the MJO. Unlike the column-integrated MSE
analysis, our method emphasizes the local production of MSE variance and
quantifies how individual physical processes amplify and propagate the
MJO’s characteristic vertical structure. We find that radiation,
convection, and boundary layer processes all contribute to maintaining
the MJO, balanced by the large-scale MSE transport. Furthermore,
large-scale dynamics, convection, and boundary layer processes all
contribute to the propagation of the MJO, while radiation slows the
propagation. Additionally, we perform mechanism-denial experiments to
examine the role of radiation and associated feedbacks in simulating the
MJO. We find that the MJO can still self-emerge and maintain its
characteristic structures without radiative feedbacks. This study
highlights the role of convective MSE transport in the MJO dynamics,
which was overlooked in the column-integrated MSE analysis.
Simultaneous multi-objective framework of natural gas pipeline network operations
Authors: Mohamed Mostafa
Published: April 2024

The optimization of gas transportation networks is essential as natural gas
demand increases. Conflicting objectives, such as maximizing delivery flow
rate, minimizing power consumption, and maximizing line pack, pose
challenges in this context. To address these complexities, a novel
multi-objective optimization method based on the Technique for Order of
Preference by Similarity to Ideal Solution (TOPSIS) is proposed. The method
generates a diverse set of Pareto optimal solutions, empowering
decision-makers to select the most suitable solution for gas transportation
networks. Three case studies validate the approach's effectiveness,
showcasing its advantages in yielding more economical networks and enhancing
the cost-effectiveness of natural gas transmission networks. The proposed
method's versatility allows application to various gas transportation
network scenarios. Decision-makers benefit from a range of Pareto optimal
solutions, providing valuable insights. Moreover, the seamless integration
of the proposed method into existing gas transportation network optimization
frameworks further enhances performance. In conclusion, the study presents a
robust multi-objective optimization method based on TOPSIS for gas
transportation network optimization. It offers cost-effective solutions and
improves the efficiency of natural gas transmission networks. The provision
of diverse Pareto optimal solutions enables well-informed decision-making,
contributing to sustainable energy solutions in the face of increasing
natural gas demand.

Authors: Lassila Lippo , Uctasli Mine B. , Wada Kanae , Vallittu Pekka K. , Garoushi Sufyan
Published: April 2024

Objectives: The aim of this article was to compare the colour stability of short fibre-reinforced computer-assisted design/computer-assisted manufacturing (CAD/CAM) composite (SFRC CAD) to commercially available CAD/CAM materials following prolonged immersion in a variety of beverages. Furthermore, the influence of the polishing technique was evaluated.
Materials and methods: A total of 120 rectangular specimens (10 mm length × 14 mm width × 2 mm thickness) were prepared from SFRC CAD, IPS e-max, Cerasmart 270, Celtra Duo, Enamic, and Brilliant Crios. The specimens underwent polishing through either a laboratory polishing machine equipped with 4000-grit silicon carbide paper or chairside polishing using Sof-Lex spiral. Twenty specimens of each tested CAD/CAM material were randomly divided into four groups (n = 5) based on the staining solution used in order to evaluate the colour stability of the materials. Group 1: distilled water, Group 2: coffee, Group 3: red wine, Group 4: coke. Using a spectrophotometer, the colour changes (∆E) of all CAD/CAM materials were assessed at baseline, and after 1 and 12 weeks of staining. Three-way analysis of variance was used to analyse the data (α = 0.05).
Results: The staining solution and material type showed a significant influence on the CAD/CAM specimens’ colour stability (p < 0.05), while polishing method had no significant influence (p > 0.05). The average ∆E values for specimens submerged in wine were considerably higher (p < 0.05) than those for the other solutions. SFRC CAD, Cerasmart 270, and Enamic displayed the highest ∆E values in wine (p < 0.05). 
Conclusions: The colour stability of tested SFRC CAD was comparable to other composite-based CAD/CAM materials, while IPS e.max exhibited the highest level of colour stability.

An update on Telomeres Dynamics in Reproduction; Specifically in Females & Ageing: A Narrative Review
Authors: KK Kaur
Published: April 2024

The oocyte portrays a postmitotic cell having a longer life working as locus of reproductive ageing in women. Female germ cells replication occurs in fetal life which age right through reproductive period. Modes behind oocyte ageing are oxidative injury, mitochondrial impairment and disturbed protein inclusive of cohesion. BobEdwards invented the “generation line” at the time of oogonial proliferation in mouse oogenesis, where the initial oocytes to leave the oogonial proliferation while fetal life are the ones which undergo ovulation first at puberty and the last oocytes to leave the oogonial proliferation are the last to undergo ovulation in adult. Hence Kalmbach K group posited ‘’second hit’’ hypothesis of reproductive ageing for incorporating to plethora of characteristics of the oocyte ageing. The 1st hit being oocyte continuing in the older women pass via more cell cycles while fetal oogenesis. The 2nd hit was oocytes which continued had>accrual of environmental & endogenous oxidative injury right through woman’s life. Telomeres (T’s) might modulate both parts of oocyte ageing. T’s offer a mitotic clock, with T debilitation becoming a granted inimical sequelae of cell division due to end replication cell botheration. The guanine enrichment of the telomeres makes them more vulnerable to oxidative injury, in post mitotic cell also. Since telomerase,/ the reverse transcriptase is more adept in sustenance rather than T lengthening. Furthermore telomerase continues to be inactive in maximum oogenesis & early generation. Thus oocytes possess small T’s on the border of viability. To corroborate this posit mice having induced T debilitation and women having natural telomeropathies have diminished ovarian reserve (DOR), aberrant embryonic generation & infertility. Conversely sperms form all through life of male by ALT, have telomerase active progenitor, spermatogonia, longest body T’s. Numerous queries arise i) does normal T debilitation of human oocytes aid in meiotic nondisjunction (MN)? ii) does recombination dependent T lengthening make embryos more prone to MN / mosaicism? iii) can certain features of T’s work as oocyte quality markers.

The Practice of Formative Assessment by Indonesian Vocational School’s English Teachers during the Covid-19 Pandemic
Authors: Bukhori Bukhori , Amaliah Siti
Published: April 2024

This study aimed to describe how Indonesian vocational school’s English teachers implemented formative assessment methods amidst the COVID-19 pandemic. The research employed a qualitative approach with a case study design. Data was gathered through interviews. Two English teachers from one of public vocational school in Rokan Hulu Regency, Indonesia participated in the study. The data analysis followed the Miles and Huberman three-step process, which included data condensation or reduction, data display, and drawing and verifying conclusions. The findings revealed that vocational school’s English teachers utilized both online and offline formative assessment strategies during the COVID-19 pandemic. Online formative assessment was implemented by using Google Classroom and Google Forms, while offline methods included quizzes, questioning and group discussions, short-answer tasks, listening cloze, role play, reading aloud, mind mapping, and dialogue writing. The teachers encountered various challenges in implementing these assessments, such as a lack of human resources, limited internet connectivity in students' homes, and some students lacking access to mobile devices. Additionally, student engagement and motivation were identified as concerns. Nevertheless, the teachers devised solutions to overcome these obstacles, including providing Wi-Fi in designated areas, encouraging students to use their parents' or friends' devices, and actively engaging with less interested students.

Published: April 2024

This study aimed to determine the cognitive level of the content in the Program for International Student Assessment (PISA) questions. This research method described the cognitive level of scientific literacy PISA questions. The cognitive level used in this study was based on the revised Bloom’s taxonomy by Anderson and Krathwohl, which includes C1 (remembering), C2 (understanding), C3 (applying), C4 (analyzing), C5 (evaluating), and C6 (creating). The PISA questions were arranged according to a predetermined theoretical framework: competence, context, knowledge, and attitude. The subjects of this research were scientific PISA questions released in 2006 and 2015, with 45 questions about the content of living systems of biological materials. The analysis of the cognitive level was presented in the form of a table and then made into a diagram so that a conclusion could be made. The results of this study indicated that PISA questions were dispersed across several cognitive levels according to the revised Bloom’s taxonomy, with the most dominant percentage of 38.24% being the cognitive analysis level (C4) in 2006 PISA and 36.36% in 2015 PISA. This study only analyzes PISA questions in the years that only focus on scientific literacy, so it needs to be analyzed in other years as well; then, it was hoped that teachers could make PISA model assessment questions with a higher cognitive level and increase the questions of students’ conceptual knowledge.
HOW CAN SOCIAL MEDIA REVOLUTIONIZE INFORMAL ENGLISH LEARNING? UNVEILING LEARNING GOALS, ADVANTAGES, AND DISADVANTAGES

Previous studies have revealed that social media (SM) was implemented in EFL (hereafter, EFL) students’ online informal learning of English (OILE). However, the information about learning goals, pros, and cons of doing these activities remains unclear. Thus, this study aimed to explore (1) the learning goals of online informal learning of English via SM and (2) the students' perceptions of the advantages and disadvantages of using SM to facilitate OILE. This basic qualitative study recruited 14 EFL students at a university in Indonesia to join in semi-structured interviews. The interview results were analyzed using inductive thematic analysis. The findings revealed that EFL students engaged in OILE via SM for various goals (mostly for form-focused and meaning-focused goals), focusing on learning and practicing language skills. However, those learning goals primarily focused on form than meaning. In addition, the participants confessed that doing OILE brought advantages to cognitive and affective domains. Unfortunately, the participants also perceived that doing such OILE also brought some disadvantages. From the findings, we offered some implications to advance EFL learning through OILE via SM.

Forecasting of catamaran roll risk situations in stormy conditions
Authors: Lipko Ivan Yur'evich
Published: April 2024

The problem of uncertainty of catamaran behavior during a storm is considered. The main danger of uncertainty lies in the magnitude of the roll by which the catamaran will deviate, since this can lead to adverse consequences with the cargo or the hull of the vessel. The study of this uncertainty is considered from two positions: the study of control actions in the implementation of the worst-case scenarios of unrest at the stage of selecting a control system and online forecasting of roll thresholds. A complex model of catamaran and external disturbances is used. External perturbations are obtained using a formative filter and linear approximation of the Pearson-Moskowitz spectrum, forces and moments. The study of the quality of management is carried out by calculating the most likely trajectories to the specified threshold states and then comparing them with each other. This calculation is performed by solving an optimization problem of the Lagrange-Pontryagin type with an action functional as a criterion and a complex catamaran model and external disturbances as a coupling equation. Using the methods of the theory of large deviations, estimates of the probabilities of movement to threshold values along the most likely trajectories are obtained. Using these estimates and comparing them with the current state of the catamaran made it possible to realize the forecast of risky situations. Examples of trajectories leading to threshold states are given for several cases of wind and heading angles of the vessel obtained with different control circuits. At the same time, it can be seen that depending on the control, fluctuations arise, which must be paid attention to when designing the control. An example of estimating the probability of movement to the threshold state during the rolling of the catamaran is given. The use of threshold state profiles allows not only to obtain useful information in the design of control systems, but also to improve the safety of navigation.
