Objective: Brain-computer interfaces (BCIs) constitute a last resort of communication for people with severe motor impairments. To date, several potential improvements of BCI-related hardware and software components have been investigated, for instance, classification algorithms for brain signals such as electroencephalography (EEG). These efforts focused on laboratory work with healthy participants. However, this is not representative for real-life conditions of potential motor-impaired end-users with diseases like amyotrophic lateral sclerosis (ALS). Our study compares state-of-the-art classification approaches on a real-life dataset of an end-user with ALS and a tactile P300-based BCI, which was obtained in long-term home-use.Approach: We applied state-of-the-art classification approaches, including Shrinkage Linear Discriminant Analysis (ShrinkLDA) and Riemannian Geometry Classifiers (RGC). Moreover, we tested effects of different calibration scenarios (i.e., amount of training data, time between calibration) and spatial filtering (using xDawn). These variations were compared to the classification results of a commonly used Stepwise Linear Discriminant Analysis (SWLDA). As a criterion for sufficient performance, we defined an accuracy of >70% (based on prior work). Main results: SWLDA could be outperformed, but without spatial filtering via xDawn, no classification algorithm was able to allow for sufficient independent home-use (with accuracies ranging between 33% to 66%; SWLDA: 59%). The addition of spatial filtering via xDawn notably improved classification results for all classifiers, with the best performance achieved by RGC_xDAWN and ShrinkLDA_xDAWN (both 72% accuracy; SWLDA_xDAWN: 70%).Significance: This is the first study comparing classifiers on a large set of tactile P300-based BCI data obtained from an end-user in his own home. Of the state-of-the-art classifiers (established with healthy participants), only two reached slightly beyond a performance accuracy of >70%. Future work can build on our findings (e.g., implement spatial filtering) and further investigate the consequences of real-life conditions for potential end-users (e.g., disease characteristics, hardware and software optimization, environmental factors).

Purpose. Rationale for the integrated use of the resource potential of coal-mining enterprises, which is aimed at obtaining technical and drinking water for their own production needs, local population and obtaining valuable substances from desalination waste. Methodology. Analysis of world experience, information about aquifer complexes in the Western Donbas mines, conducting chemical analyses of mine waters and salt mixtures obtained after using reverse osmosis products. Results. Based on the accumulated world experience in desalination of highly mineralized waters, it can be concluded that it is possible to effectively implement this experience at mining enterprises. Description of aquifer complexes has been given in detail using the example of the Zakhidno-Donbaska Mine of PJSC “DTEK Pavlohradvuhillia”, chemical analyses of water before and after discharge into settling ponds. A rational technological scheme for desalination, volumes of purified water obtained for drinking and technical water supply, as well as the quantitative and qualitative composition of the dry residue components of mine water desalination waste, and recommendations on possible use of products on the market have been determined. Scientific novelty. Analytical and laboratory studies have been conducted to determine the component composition of mine water desalination waste from Western Donbas coal-mining enterprises. It has been determined that the resulting salt product is a mixture of pure salts and valuable microcomponents, and the resulting distillate is fuel for the operation of hydrogen electrolyzers, which creates prerequisites for modern “green” hydrogen energy infrastructure. Practical significance. The qualitative and quantitative mine water parameters on complex use as an alternative source of water supply and obtaining related reverse osmosis products have been analyzed. The road services propose the consumption of the resulting salt products by municipal enterprises, and the dry distillation residue – to prevent dust. This approach allows solving not only the problem of desalination waste utilization, but also applying the separated valuable substances in the industrial market of food, medical, cosmetic, paint and varnish, chemical, as well as building materials, plastics and polymers production industries. Keywords: mine water, waste recycling, mineral resource, coal-mining enterprises.

Purpose. The search for methods for the formation of comprehensive statistics of industrial injuries at the enterprises of Ukraine and the creation of a system of measures to reduce the level of injuries and incidents based on it. Methodology. To achieve the goal of the study, methods of information collection and generalization, critical analysis, analytical methods (analysis of injury statistics in a number of countries), system analysis methods (for formulating theoretical and applied generalizations) have been used. Results. The relevance of determining the root causes of incidents and injuries without loss of work capacity using the "injury pyramid" has been considered. On the basis of data from the International Labor Organization on the level of industrial injuries, it has been assumed that there is a significant percentage of hidden injuries in Ukraine and that employers are not interested in keeping records of microinjuries and incidents. The application of the "incident accounting and analysis system" has been proposed as a method that allows employers and labor protection services of enterprises to form comprehensive statistics about the state and working conditions at the enterprise. Based on the collected data, employers will be able to identify the causes of injuries and directly influence the causes of their occurrence. Scientific novelty. The novelty of the research consists in the first substantiated possibility of using record cards and incident analysis as a means to reduce the level of industrial injuries. Practical significance. Preservation of the life and health of employees in the process of work is a priority of work safety specialists. Decision-making regarding the implementation of labor protection measures should be based on reliable data. The use of the proposed incident accounting and analysis system allows identifying the root causes of production incidents and may become the basis for making informed decisions for their elimination. Keywords: occupational injuries, injury pyramid, accounting and analysis of incidents, occupational safety, level of injuries.

Authors: Gago Maria Paula
Published: July 2024

Introducción: Este artículo analiza las agendas policiales de los diarios Clarín y La Nación desde la derrota en la guerra de Malvinas (1982) hasta la asunción del presidente Raúl Ricardo Alfonsín (1983). El objetivo es comprender de qué manera las condiciones sociales e históricas de producción incidieron en las agendas policiales de ambos medios. Metodología: Para analizar el corpus en sus niveles temático, retórico y enunciativo en relación con sus condiciones sociales e históricas de producción se articulan categorías operativas de la sociosemiótica y del análisis del discurso. Resultados: Los crímenes políticos se incorporan y conviven con los delitos comunes en los sumarios informativos de cada diario. Discusión: Aunque existen diferencias en los contratos de lectura de Clarín y La Nación, hacia 1982 tratan los hechos policiales con una clave interpretativa política, lo cual representa un cambio respecto a las narrativas mediáticas sobre el delito empleadas en los primeros años del gobierno dictatorial. Conclusiones: La noticia policial tiene una intencionalidad política. Asimismo, cada momento histórico supone sus propios modelos delictivos y delincuenciales y a partir de su estudio es posible contribuir a la explicación y comprensión de la coyuntura histórica y social en la cual suceden.
Michoacán en el Censo de Revillagigedo de 1790. Cotejo con los datos de Martínez de Lejarza de 1822
Authors: Talavera Ibarra Oziel ,   Universidad Michoacana de San Nicolás de Hidalgo
Published: July 2024

This article is based on a statistical analysis of the data provided by the 1790 Revillagigedo Census for the intendancy of Valladolid, which at the end of the Colonial period corresponded mostly to the current state of Michoacán. From these data, fundamental information about Michoacán society at the end of the colonial era was obtained, including aspects such as the total population, sex ratio, age groups, percentage by racial category, population distribution by sub-delegation, and population density, among others. Additionally, a comparison with the statistical study by Martínez de Lejarza in 1822 is offered. It is shown that this intendancy was experiencing population growth, with a slight male advantage over females, and had a young society, as its age groups display a pyramidal shape characteristic of the old demographic regime. Regarding racial categories, it is also shown that most Michoacán inhabitants were not indigenous, although significant regional differences are presented, such as markedly indigenous areas and others with a majority of castes and Spaniards. Other aspects revealed here include the difference in population density between regions and that much of the active male population was engaged in the primary sector.

Reading from the screen of an electronic device (ED) is a significant cognitive activity for adolescences, and its complexity affects visceral functions. We conducted an analysis of the heart rate variability (HRV) and eye movements (EM) in adolescents while they were reading complex text on an ED screen. The aim was to assess the functional state characteristics under these conditions and reveal the intensity (“cost”) associated with this activity The study involved 22 adolescences with an average age of 15 years (М = 15.46, SD = 0.44). Reading text from an ED screen in adolescents was associated with a high functional “cost,” characterized by a decrease in overall HRV, an increase in the tension index and heart rate. These changes indicate the functional tension of regulatory systems during cognitive activity. The study revealed varying levels of parafoveal processing involvement. For the majority of adolescents (86.4%), word-by-word reading and a low percentage of regressions (12.0%) were observed, suggesting developed average reading skill. However, a qualitative analysis of individual EM tracks indicated varying level of reading skill development among adolescents, possibly due to a limited vocabulary and a lack of understanding of syntax. Additionally, 40.9% of adolescents demonstrated poor text comprehension. Our results showed that reading remains a complex cognitive task for adolescents, despite the expectation that their reading skills should be well-developed and automated by this age. Individual analysis of HRV and EM in adolescents with varying levels of text comprehension during reading demonstrated different strategies of adaptive behavior and autonomic reactions when performing a complex cognitive task. The functional “cost” of information processing when reading text from the ED screen results from a combination of age-related and individual adaptation characteristics, language competence and the psycholinguistic complexity of the text.
Optical Apparatus of the Eye under Conditions of “Dry” Immersion
Authors: Gracheva M. A. , Manko O. M.
Published: July 2024

The studies of the astronauts’ vision show that after space flight various changes can occur in the visual system: flattening of the eyeball, optic disc edema, hyperopic refractive shift, and others. The mechanisms of those changes are being actively studied. Among model experiments simulating aggressive factors of space flight, experiments on modeling microgravity in conditions of “dry” immersion seem to be one of the most promising in terms of studying eye changes. The aim: to evaluate the prospects of using “dry” immersion as a model for studying intraocular changes in space flight conditions. The paper presents data on the evaluation of the eye condition of the test subjects after being in the immersion bath for 5 days (10 subjects) and 21 days (6 subjects). Refraction and dynamic accommodation were evaluated in all subjects using an autorefkeratometer Righton Speedy-i k-model with dynamic accommodation assessment function. The refraction data showed a trend toward a positive refractive shift of 0.11 diopters on average for 5 days of immersion (confidence interval (–0.06)–(+0.28)) and 0.29 diopters for 21 days of immersion (c.i. (–0.28)–(+0.86)); no statistical significance of the differences was confirmed, which may be due to the small number of subjects and the limited power of the statistical criterion. However, the trend requires further investigation. A significant individual variation was shown in the results of accommodation assessment. Preliminary data suggest that “dry” immersion may be a promising model for studying the effects of reduced gravity on the human visual system. Further studies are needed.

Integrated indicators of systemic endotoxemia (SEE): the level of endotoxin (ET) and the concentration of antibodies to the hydrophobic (AT-LPS-FOB) and hydrophilic (AT-LPS-PIL) forms of the lipopolysaccharide (LPS) molecule in the general circulation can be used to determine the risk category of atherosclerosis development and progression, which dynamics is an objective marker of aging rate. The comparison of images the structure of brachycephalic arteries wall in dynamics with changes in blood parameters is one of the most successful models for monitoring the atherosclerotic process in a clinical setting. 42 people were examined without the presence of recognized risk factors for the progression of atherosclerosis at baseline and after 1.5-2 years. It was found that lipid profile indicators, such as the concentration of total cholesterol, low and high density lipoproteins, triglycerides, atherogenic index had no prognostic value. Whereas in the group with the progression of damage to the arterial wall, an increase in the concentration of ET was noted with a decrease in the concentration of AT-LPS-FOB and AT-LPS-PIL. In the group with regression of atherosclerotic changes, on the contrary, against the background of a decrease in the concentration of ET, an increase in AT was noted. A prospective study revealed an extremely important fact of a decrease in the concentration of LPS in the blood of patients with positive dynamics of morphological manifestations of atherosclerosis, indicating both the reversibility of the atherosclerotic process and the participation of ET in atherogenesis, which is a real way for extending the life of an individual and indicates the direction to achieve this goal – “antiendotoxin therapy”.
Neurotrophic Hypothesis of Development of Depression

Published: July 2024

Currently, depression is a widespread mental disorder in modern society and is associated with significant impairments in the quality of life of patients. The review examines the main representatives of neurotrophic factors belonging to various families, in particular nerve growth factor, transforming growth factor beta, neurokines and non-neuronal factors. Neurotrophins, being large polypeptides, play an integrative role, fulfilling the signaling mission of intermediaries in a wide range of physiological processes. At the moment, a large number of studies have been carried out in order to understand the interaction between factors of various directions, including biological, psychological and environmental factors that determine the etiopathogenesis of this pathology. Based on the data obtained, one of the main hypotheses for the development of depression is considered - neurotrophic, which most fully explains the emerging pathogenetic changes. According to this hypothesis, the leading role in the etiology of depression is played by neurotrophic factors that ensure the maintenance of normal neuron-glial interaction, the processes of neurogenesis, angiogenesis, and synaptic plasticity. Neurotrophins have a high physiological activity due to the presence of several binding groups for different cell receptors and the regulatory ability to express other signaling molecules, the ability to penetrate the blood-brain barrier, showing trophic, anti-inflammatory, growth, mediator and effector properties. To date, the mechanisms of the onset of depression, despite the widespread prevalence of this pathology, remain largely unclear, hindering a directed search for targets for the development of effective therapy. The revealed disorders of neurotrophic factors in depression make it reasonable to consider neurotrophins as therapeutic agents in a multitarget approach to the treatment of depressive disorders.

Authors: Lyubimova A. V. , Eremin D. I.
Published: July 2024

The studies were conducted to assess the dependence of the biochemical parameters of oat grains (crude protein, starch, oil and β-glucans) on the genotype and weather conditions to determine the prospects for their use in the breeding process. In the forest-steppe of the Trans-Urals in 2021–2023, 21 samples of naked and 64 samples of covered oats were studied, which are most actively used in breeding in Western Siberia. Tyumen nudibranch was taken as the standard for naked cultivars, and for covered cultivars it was Otrada. It was found that the genotype played a significant role in the content of crude protein and β-glucans in oat grain (78…80 %); weather conditions – 12…15 %, with minimal interaction of these factors – 4 and 7 % (Ffact . Ftheor.) respectively. Retention of oil and seaweed at 85…86 % exceeds the permissible values, and now to a minimum extent – 3 and 6 %, respectively (Ffact. Ftheor.). The effect of the genotype and the subsequent level on the oil content is 11 %. A close relationship between content and consumption has been established. Protein and oil in naked oats (r=0.96; p=5 %), in frequent cases it was the average (r=0.25; p=5 %). The content of β-glucans had an inverse average correlation with protein in the grain of filmy genotypes (P= –0.38), it was absent in nudibranchs. A negative correlation was established between the content of β-glucans and oil (g= –0.32; p=5 %) in covered samples. The analysis of variance and correlation showed the possibility of targeted selection in terms of protein and oil content. It is recommended to introduce the following genotypes into the breeding process to increase the content: starch (60.1…62.3 %) – Vyatsky (14960), MF 9521–281 (15096), MF9714–32 (15227), Progress (15339), Korolek (15461); β-glucans (6.1…6.3 %) – Rovesnik (14365), Argamak (14648), Neklan (14936), Konkur (15068); Ozone (15473); protein (16.1…17.5 %) – Rovesnik (14365), Percheron (15275), Pomor (15117), Taidon (15183); oils (6.1…7.4 %) – Sapsan (15444), Pegas (15114), Petrovich (15691).

Published: July 2024

Interest in growing ancient wheat species and studying the possibility of their use as raw material for feed preparation has increased recently. Indian dwarf wheat (Triticum sphaerococcum Percival) is one of the promising grain crops. The aim of the study was to determine the nutritive value of ears of Indian dwarf wheat in different phases of ripeness for use as raw material in the production of feed in comparison with soft wheat and to determine the rational time frame of their harvesting for feed preparation. Harvesting was carried out by combing without threshing and separation of grain heap in different phases of maturity. The feed was prepared from the grain heap. Chemical analyses of feed samples were performed according to standard methods. The mid-wax ripeness phase is the optimum harvesting time of Indian dwarf wheat for preparation of feed from its ears. Its ears in this phase contain maximum essential amino acids and minimum cellulose. Feed prepared from ears of Indian dwarf wheat has a better quality than feed from soft wheat, as it contains 1.06–2.23 % more of the sum of essential amino acids and 1–5 % more of individual amino acids. This allows the crop to be used in feed preparation to improve protein quality. But its 4–10 % more higher cellulose content than feed from soft wheat is a disadvantage. Grain heap (ears) of Indian dwarf wheat, harvested without threshing in the phase of early wax and mid-wax ripeness, can be a source of increasing the nutritive value of feeds, as it contains more essential amino acids than soft wheat.

Authors: Lobachevsky Ya. P. , Kirsanov V. V. , Kirsanov S. V.
Published: July 2024

The Carousel, the most capital–intensive and loaded milking unit, is a rotating platform that carries a large mechanical load. Its own weight, combined with the weight of the animals being moved, can reach 1200 kg per milking place or more. To reduce friction in the wheeled systems of high-loaded vehicles, large-sized assemblies and mechanisms of machinery and equipment, including agricultural machinery and aggregates, the use of magnetic suspension technology is promising. The research was carried out in order to develop a new technological scheme of a levitating rotating milking platform Carousel based on the principles of magnetic levitation. The creation of a fundamentally new resource-saving design of the Carousel milking platform based on the principles of magnetic levitation in order to increase its reliability and reduce operating costs due to the exclusion of wear on the propellers of the rail-wheel system is possible. A new scheme of a rotating milking platform Carousel using permanent magnet magnetic suspension technology without the use of wheel thrusters is proposed. Its force calculation was performed in the main mode of steady motion with the platform fully filled with animals and partially filled at the beginning and end of the milking cycle of animals, obtaining basic equations for determining the necessary repulsive forces in horizontal and vertical magnetic assemblies providing magnetic levitation (suspension) and lateral stabilization (centering) of the rotating platform.

Published: July 2024

The studies were carried out in 2018–2022. in the Samara region in order to identify the influence of the parameters of the carbohydrate-amylase complex and protein content in grain on baking properties in order to use the most informative indicators in the selection of winter rye for baking in the conditions of the Middle Volga region. The material was 4 varieties and 3 promising lines – Saratovskaya 7 (standard), Bezenchukskaya 87, Bezenchukskaya 110, Antares and lines GK-80, GKNP-3, GKNP-4. The soil is ordinary chernozem, medium deep, medium loamy, predecessor is pure fallow, repeated four times. The main parameters that determine the state of starch and influence the rheological properties of rye dough and baking evaluation reached: the «falling number» indicator – 188…255 s, the maximum viscosity on the amylograph – 424…570 u. a. The relationship between the height of the ammylogram and the «falling number» in 2019, 2020 and 2022. was strongly positive (r= 0.95; r= 0.89; r= 0.92). In 2020 and 2021 There was a positive correlation between the height of the amylogram and the volumetric yield of bread (r = 0.86; r = 0.82), the falling number also in these years was significantly positively correlated with the volumetric yield of bread (r = 0.65; r = 0.76). On average, over the years of research, the content of water-soluble pentosans, depending on the variety, varied from 2.46 to 3.00 %. In 2019, the highest values of this indicator were noted – 2.70…3.55 %, the volume of bread was also the highest – 520…655 cm3, and only this year a positive relationship was noted between the values of these indicators (r = 0.72). The relationship between pentosans and the «falling number», which is also responsible for the baking properties of winter rye, was significantly positive in 2019, 2020 and 2022. (r= 0.80; r= 0.78; r= 0.70). Protein content was positively correlated with bread volume yield (r=0.80; r=0.75) only in 2018 and 2019. A negative correlation was established between protein content and amylogram height in 2019, 2020, 2021, 2022. (r= –0.80; r= –0.80; r= –0.82; r= –0.78). There is also a negative relationship between protein content and the number of falls in 2019, 2020 and 2022 (r = –0.84; r = –0.80; r = –0.67). When selecting varieties of winter rye for baking, it is necessary to carry out conjugate selection based on the height of the amylogram and the «falling number» while stabilizing the protein at an acceptable level of 12.0…12.8 %.

The article aims to identify the effect of body postures and air ventilation rates on the volume and thickness of the air gap under air ventilation garments (AVGs). The geometric models of the human body and clothing were obtained by using a 3D body scanner. Then the distribution of air gap volume and thickness for five postures (standing, arm flatting, arm lifting, sitting, and trunk bending) and three air ventilation rates (0L/S, 12L/S, 20L/S) were calculated by Geomagic software. The results showed that both body postures and air ventilation rates significantly influenced the air gap entrapped. Among the five postures selected, the air gap thickness (AGT) in the arm lifting posture is always in a thicker state, and when the air ventilation rate reaches high speed (20L/S), the maximum AGT in the chest is 0.086 m, and the maximum AGT in the waist is 0.092 m. This research provides an improved comprehension of the distribution of air gap entrapped in AVGs.
GRID-STEP OPTIMIZATION OF THE PARAMETERS OF THERMAL IMPACT ON THE TECHNICAL SYSTEM

Published: July 2024

The article solves applied problems of optimizing the parameters of technical systems under the influence of concentrated, discrete sources of thermal load. To improve the accuracy and speed of solving applied optimization problems, the authors propose a generalized procedure for finding the optimal thermal load parameters. This procedure consists of well-known computational methods for solving boundary value problems and ensuring the optimization of the objective function and its parameters.
To calculate the values of the temperature field, it is necessary to solve a nonlocal boundary value problem of a system of nonlinear differential heat transfer equations. In order to find the conditions for the correctness of boundary value problems, the authors used the theory of pseudo-differential operators in the space of generalized slow power functions. This made it possible to guarantee the correctness of computational and applied optimization mathematical models.
The procedure for grid-step optimization of the parameters of thermal action on a multilayer material proposed by the authors is based on a grid approach with discretization of the main parameters of thermal load and grinding of a large uniform grid in the vicinity of the selected node of the large grid. The directed search for local extremes of the mesh model is carried out by the nodes of the crushed mesh. The search for local extrema is performed by selecting the next node of a large grid. This approach will increase the accuracy of solving applied optimization problems by allowing further mesh refinement and refinement of the values of local extremes, and, consequently, refinement of the values of the global extremum of the objective function. The optimization of the thermal impact parameters was carried out according to the criterion of reducing damage to the test material. This makes it possible to increase the accuracy of the technological process of thermal action on a multilayer material.

Efficient Workflow Analysis to Address Paper Persistence in Tuberculin Testing
Authors: Thompson Sarah A. , Dawson Eli , Kandswamy Swaminathan , Orenstein Evan
Published: July 2024

Despite widespread adoption and maturity, paper persistence endures in many Electronic Health Record (EHR) systems, particularly for complex workflows involving multiple steps from different stakeholders separated in time. In our health system, Latent Tuberculosis Infection (LTBI) testing was one such workflow where a Tuberculin Skin Test (TST) must be administered and then correctly read 48-72 hours later and documented. This paper discusses a low-resource workflow analysis and clinical decision support approach to replace a paper workflow and garner the benefits of the EHR for clearer documentation and retrieval of LTBI results. Our approach resulted in a significant increase in completed TST documentation, 57% (24/42) to 95% (18/19), P < 0.003. Human-centered design practices such as work system analysis and formative usability testing are feasible with limited resources and improve the likelihood of success of electronic workflows by designing solutions that fit existing clinical workflows and automating processes wherever possible.

Authors: Choi Jeeyae , Tarte Valerie , Bove Lisa Anne , Kim-Godwin Yeounsoo
Published: July 2024

The advancement of technology and Artificial Intelligence applied health information systems demand high informatics competencies from nurses. To prepare nursing students to meet this demand, informatics courses are designed to increase informatics competencies. We offered an online informatics course to graduate students in a Nurse Educator program and assessed their informatics competency, including subdomains. Survey data were collected between Fall 2020 and Fall 2022 using an online Self-Assessment of Informatics Competency Scale for Health Professionals. We analyzed 109 responses and found that students were competent in overall informatics competency and the subdomains of “basic computer skills” and “applied computer skills (clinical informatics).” They were proficient in the ‘role’ subdomain. However, students reported less competency in managing data and incorporating standard terminology into practice. These findings provide detailed insights of the current nursing students’ informatics competencies and can guide informatics faculty in improving their courses.
What Is the Level of Nursing Informatics Competency of ChatGPT?
Authors: Choi Jeeyae , Lee Hanjoo
Published: July 2024

Nurses must excel in using Artificial Intelligence (AI) - applied hospital systems, making their informatics competency crucial. ChatGPT has been trained with extensive amounts of informatics- and technology-related health data and has gained popularity. Nurses could have the opportunity to enhance their informatics competency through the knowledge generated by ChatGPT. However, its informatics competency has not been evaluated. We used the Self-Assessment of Informatics Competency Scale to measure the level of informatics competency of ChatGPT. ChatGPT fell within the range of ‘somewhat competent’ and ‘competent,’ lower than that of students in graduate programs. One subdomain, applied computer skills (clinical informatics), demonstrated competency levels close to that of students. Although the results presented certain limitations and concerns, we recognize the potential of ChatGPT to help researchers and healthcare practitioners. Nursing is advancing and continuously integrating AI technology; therefore, we should now embrace both the benefits and risks associated with ChatGPT.
