Published: February 2024

Parallel robotic systems have shown their advantages over the traditional serial robots such as high payload capacity, high speed, and high precision. Their applications are widespread from transportation to manufacturing fields. Therefore, most of the recent studies in parallel robots focus on finding the best method to improve the system accuracy. Enhancing this metric, however, is still the biggest challenge in controlling a parallel robot owing to the complex mathematical model of the system. In this paper, we present a novel solution to this problem with a Type 2 Fuzzy Coherent Controller Network (T2FHC), which is composed of a Type 2 Cerebellar Model Coupling Controller (CMAC) with its fast convergence ability and a Brain Emotional Learning Controller (BELC) using the Lyaponov-based weight updating rule. In addition, the T2FHC is combined with a surface generator to increase the system flexibility. To evaluate its applicability in real life, the proposed controller was tested on a Quanser 2-DOF robot system in three case studies: no load, 180 g load and 360 g load, respectively. The results showed that the proposed structure achieved superior performance compared to those of available algorithms such as CMAC and Novel Self-Organizing Fuzzy CMAC (NSOF CMAC). The Root Mean Square Error (RMSE) index of the system that was 2.20E-06 for angle A and 2.26E-06 for angle B and the tracking error that was -6.42E-04 for angle A and 2.27E-04 for angle B demonstrate the good stability and high accuracy of the proposed T2FHC. With this outstanding achievement, the proposed method is promising to be applied to many applications using nonlinear systems.

In a rapidly evolving landscape where automated systems and database applications are increasingly crucial, there is a pressing need for precise and efficient object recognition methods. This study contributes to this burgeoning field by examining the ResNet-18 architecture, a proven deep learning model, in the context of fruit image classification. The research employs an elaborate experimental setup featuring a diverse fruit dataset that includes Rambutan, Mango, Santol, Mangosteen, and Guava. The efficacy of single versus multiple ResNet-18 models is compared, shedding light on their relative classification accuracy. A unique aspect of this study is the establishment of a 90% decision threshold, introduced to mitigate the risk of incorrect classification. Our statistical analysis reveals a significant performance advantage of multiple ResNet-18 models over single models, with an average improvement margin of 15%. This finding substantiates the study’s central hypothesis. The implemented 90% decision threshold is determined to play a pivotal role in augmenting the system’s overall accuracy by minimizing false positives. However, it’s worth noting that the increased computational complexity associated with deploying multiple models necessitates further scrutiny. In sum, this study provides a nuanced evaluation of single and multiple ResNet-18 models in the realm of fruit image classification, emphasizing their utility in practical, real-world applications. The research opens avenues for future exploration by refining these methodologies and investigating their applicability to broader object recognition tasks.

Published: February 2024

This study addresses the critical need for efficient room monitoring and air conditioning systems, particularly in educational settings like the STMIK STIKOM Indonesia campus. The paper introduces a novel approach that combines ESP-12E based sensors with Proportional-Integral-Derivative (PID) control automation to optimize air conditioning efficiency. Utilizing an ESP-12E microcontroller, the study designed and implemented a room monitoring tool equipped with DHT22 and BH1750 sensors for accurate measurement of temperature, humidity, and light intensity. We also explores the integration of a PID control system into an existing air conditioning (AC) unit. The PID controller was fine-tuned to maintain a stable indoor temperature of 25oCelsius, even when subjected to external heat loads, such as ten LED lamps. The effectiveness of this system was quantified through real-time monitoring of temperature, humidity, and energy consumption, both pre- and post-implementation. Results indicated a rapid and stable response from the PID controller, achieving an amplitude of 1 within 0.08 seconds, thereby confirming its successful tuning and adaptability. We found that this study has broader implications for enhancing energy efficiency and creating conducive learning environments. However, it is worth noting that the research was conducted under specific conditions, and further studies could explore its applicability in different settings.

Published: February 2024

In this paper, a passivity-based control combined with sliding mode control for a DC-DC boost power converter is proposed. Moreover, a passivity-based control for a DC-DC boost power converter is also proposed. Using a co-ordinate transformation of state variables and control input, a DC-DC boost power converter is passive. A new plant is zero-state observable and the equilibrium point at origin of this plant is asymptotically stable. Then, a passivity-based control is applied to this plant such that the capacitor voltage is equal to the desired voltage. Additionally, the sliding mode control law is chosen such that the derivative of Lyapunov function is negative semidefinite. Finally, a passivity-based control combined with sliding mode control law is applied to this plant such that the capacitor voltage is equal to the desired voltage. The simulation results of the passivity-based control, the sliding mode control and the passivity-based control combined with sliding mode control demonstrate the effectiveness and show that the capacitor voltage is kept at the desired voltage when the desired voltage, the input voltage E and the load resistor R are changed. The results show that compared with the passivity-based control, the passivity-based control combined with sliding mode control has better performance such as shorter settling time, 8.5 ms when R changes and it has smaller steady-state error, which is indicated by the value of integral absolute error (IAE), 0.0679 when the desired voltage changes. The paper has limitations such as the assumed circuit parameters.
Design of an Integral Fuzzy Logic Controller for a Variable-Speed Wind Turbine Model
Authors: Almaged Mohammed , Mahmood Ali , Alnema Yazen Hudhaifa Shakir
Published: February 2024

The demand for electricity is continuously growing around the world and thus the need for renewable and long-lasting sources of energy has become an essential challenge. Wind turbines are considered one of the major sources of renewable electricity generation. Therefore, there is a crucial demand for wind turbine model and control systems that are capable of precisely simulating the actual wind power systems. In this paper, an advanced fuzzy logic controller is proposed to control the speed of a wind turbine system. Initially, aero dynamical, mechanical and electrical models of two mass wind turbines models are derived. Analytical calculation of the power coefficient is adopted through a nonlinear function of six coefficients that mainly depends on pitch angle and tip speed ratio. The ultimate power output from the turbine can reach up to 50 % which is achieved at zero pitch angle with an approximately tip speed ratio of eight. This is then followed by designing a hybrid fuzzy-plus I pitch controller to regulate the speed of the wind turbine shaft. In general, fuzzy logic control strategy have the advantages over traditional control techniques especially when the system is highly non-linear and has to deal with strong disturbances such as wind turbulence. To evaluate the reliability and robustness of the controller, the response of the wind turbine system is tested under several types of disturbances including wind fluctuation, sudden disturbances on high and low speed shafts. Simulation findings reveals that the performance of fuzzy-integral control technique outweighs that of conventional fuzzy approach in terms of multiple performance evaluation indexes such as zero overshoot and steady state error, rise time and a settling time of (32.9 s) (44.7 s) respectively. The reliability and robustness of the controller is tested by applying speed and torque disturbances of 25% of their maximum ranges. Results have revealed that the controller was able to reject all disturbances efficiently with a change in pitch angle up to a maximum of 10 degrees in order to retain a constant rotor speed at 1000 rpm.

Regionalização, cidades e urbanodiversidade na Amazônia brasileira
Authors: Trindade Júnior Saint-Clair
Published: February 2024

Sustenta-se que a complexidade socioespacial amazônica exige reconhecimento de sua diversidade natural (biodiversidade), social (sociodiversidade) e urbana (urbanodiversidade). Para isso, mostram-se particularidades sub-regionais da Amazônia brasileira e a diversidade urbana delas decorrente. O argumento central considera a noção de espaço socialmente produzido e a perspectiva teórico-metodológica do desenvolvimento geográfico desigual e diferenciado, de forma a mostrar, a partir de diferentes tipos de cidades, a expansão de frentes capitalistas na região, assim como contrarracionalidades e resistências de natureza econômica, política e sociocultural que configuram o território regional internamente. Conclui-se, chamando a atenção para a necessidade de políticas territoriais e urbanas descentradas que estejam em plena sintonia com as particularidades regionais, de modo a garantir tomadas de decisão e formas de gestão que se contraponham às tendências de homogeneização do espaço regional e de padronização da vida urbana.

The article is devoted to the analysis of organization of the educational process for physical education of students in universities, which is obliged to ensure the formation of students with the necessary universal competencies in accordance with the requirements of the Federal State Educational Standard of Higher Education. According to many authors, the existing organization of physical education does not allow students to form those universal competencies that should motivate them to regularly perform physical exercises to maintain a proper level of physical fitness and maintain a healthy lifestyle. The Olympiads conducted by the authors to assess students’ knowledge of the basics of health-improving physical culture and an online survey of students about self-training classes in physical culture showed that the residual level of necessary knowledge among students is low, and most of them are not engaged in physical self-training. In order to improve the current situation in universities, the Scientific and Methodological Council for the Development and Disciplines (Modules) on Physical Culture and Sports of the Ministry of Science and Higher Education of the Russian Federation needs to consider improving the educational process for physical education of students.

Hidden Behind Chronic Dyspeptic Symptoms: Post-traumatic Diaphragmatic Eventration
Authors: YILDIZ Latife Merve , CUBUKCU Mahcube
Published: February 2024

Abstract

Diaphragmatic eventration is commonly seen following high-energy traumas, particularly due to traffic accidents and falls from significant heights. This pathology has the potential to influence both the gastrointestinal and cardiorespiratory systems, presenting with a variety of symptoms. A 45-year-old male patient, with a history of trauma from falling off a tree, sought medical attention at our clinic with dyspeptic complaints and symptoms of shortness of breath. During the physical examination, diminished sounds were detected in the right lung field, along with epigastric tenderness. For diagnostic purposes, a posteroanterior chest radiograph (CXRs) and thoracic computed tomography (CT) scan were obtained. A subsequent bronchoscopy, performed with a pulmonology consultation, revealed decreased diaphragmatic movements. Taking into account the findings, a thoracic surgery treatment plan was devised for the patient. This case report underscores the significance of considering the seldom-encountered pathology of diaphragmatic eventration in patients presenting with dyspeptic and respiratory complaints. Keeping in mind that patients with such symptoms frequently turn to family physicians, it highlights the pivotal role of a multidisciplinary primary care approach in initiating the diagnostic trajectory.
Toponyms as constructs of military dimension in the Ukrainian poetic discourse of 2022–2023
Authors: Brailko Іuliіa
Published: February 2024

Background. The onym dimension of artistic expression undergoes noticeable transformations under the influence of important historical events. The armed aggression of the Russian Federation, which began in 2014, and especially its full-scale period, could not help but affect the mentality of Ukrainians, and their literary creativity, and, accordingly, the selection, organisation and coding / recoding of linguistic means in lyrical texts.Contribution to the research field. The author’s scientific interests are focused on literary onomastics and the study of changes in the Ukrainian discourse of the modern era. The analysis of toponyms in the Ukrainian poetic discourse of the period of the full-scale armed aggression of the Russian Federation has not yet been the subject of close research attention. These findings raise intriguing questions regarding the extent of society’s diverse speech response to the colossal tragedy.Purpose. The purpose of this research is to investigate the peculiarities of the development of toponymy in modern poetic discourse using the example of the latest constructions of military dimension.Methods. The article uses the sampling method, method of classification description, comparative-semantic method and contextual-interpretive analysis.Results. Modern poetic discourse has significantly expanded its placename dimension with the latest markers of the Russian-Ukrainian war, which are structured into the opposition “own – enemy” / “own – foreign.” The appearance of such precedent units is determined by an extralinguistic factor, and their choice is determined by the authors’ artistic guidelines and the personal perception peculiarities of the tragedy. The highest productivity in the construction of military dimension is shown by oeconyms represented by the largest number of lexemes denoting the places of hostilities (Bakhmut, Beryslav, Burluk, Bucha, Borodianka, Brovary, Volnovakha, Vorzel, Horenka, Hostomel, Enerhodar, Izium, Irpin, Kakhovka, Kyiv, Konotop, Kramatorsk, Kupiansk, Manhush, Mariupol, Mariinka, Mykolaiv, Moschun, Olenivka, Oleshky, Okhtyrka, Romanivka, Soledar, Kharkiv, Kherson, Chernihiv, Shchastia, etc.), rear (Lviv, Chernivtsi, Uzhhorod, Ivano-Frankivsk, Ternopil), places where the enemy is located (Perm, Irkutsk, Rostov) and places where refugees are sheltering (Krakow, Warsaw, Lisbon, Cascais). It is natural that the toponymic constructs of the military dimension consistently actualize the semantics of martyrdom, suffering, and death, often against the background of sacralization.Discussion. We see research prospects in the continuation of the study of the open toponymic dimension of modern Ukrainian poetry as a powerful construct of the artistic understanding of war.
National we in Ukrainian media texts in 2022: construction of identity during the anti-colonial war
Authors: Yasakova Nataliia
Published: February 2024

Background. National identity is a dynamic phenomenon that is discursively constructed through use of various language means, including the pronoun “we.” Perception of a nation as a political community results in usage of the national we in specific contexts, while practical use of the national we in various discourses has an impact on construction and support of the national identity.Сontribution to the research field. This research sets the parameters of discursive construction of the Ukrainian national identity represented in the media texts through use of the national we.Purpose. The purpose of this article is to analyse the use of the national we that appeared in Ukrainian media texts in the year of the full-scale Russian invasion of Ukraine. Study materials were selected from the articles published on The Ukrainian Week’s website during 2022.Methods. A descriptive method was used for this research as a part of the discourse analysis.Results. Semantic zones related to the discursive construction of the Ukrainian national identity using the national we were highlighted: 1) the need to understand one’s national identity; 2) national character (stereotypical Ukrainian); 3) physical measurement of existence of a nation (people and territories); 4) historical memory; 4) culture; 5) present; 6) future; 7) tasks to be solved for adequate existence of the nation. The important element of understanding the national uniqueness is determining one’s distinction from the enemy which, among other things, is verbalised through we — they opposition. The common past that determines the present and the future, and the tasks the Ukrainians face are mentioned more often than the other semantic zones.Discussion. In all semantic zones construction of the national we is affected by the colonial past of Ukraine and the necessity to resist the Russian imperial narratives and defend against the full-scale armed invasion of Russia. The direction for the research is to study the discursive construction of the Ukrainian national identity during ХХ–ХХІ centuries in the context of the postcolonial research trends using various language means.

A comparative assessment of the characteristics of myocardial and vascular damages as well as their occurrence in patients with decompensated chronic tonsillitis (CT) sent to the hospital for planned tonsillectomy were carried out. 179 people aged 18 to 25 years were examined. Two groups were formed: group 1: patients with decompensated СT (102 people) and group 2: control – that is, persons without СТ (77 people). We used 24-hour ECG monitoring (Holter) with a set of additional diagnostic options and EchoCG to determine various characteristics of myocardial activity. The arterial wall was assessed using indicators of vascular stiffness and assessment of blood pressure balance in the vascular territories. We used hardware-diagnostic complexes DMS Advanced Technologies (Russia) and RuSkan-70P (Russia). Myocardial damage was judged by exceeding the upper limit of the permissible norm for such indicators as the number of extrasystoles per hour, the maximum rate of increase in pressure in the aorta (dP/dTmax), and the size of the heart chambers; and damage to the vascular wall was judged by similar changes for the aortic pulse wave (PWVao), aortic reverse pulse wave augmentation index (AIx ao), and ankle-brachial index (ABI). The individual profile of the main cardiovascular risk factors was also assessed. Data processing was carried out using the Statistica 10.0 software package (StatSoft Inc., USA). The results indicated the presence of a negative effect of СТ not only on the myocardium with the development of some moderate changes but also on the vascular wall. The latter violations were recorded significantly more often. Vascular disorders were characterized by increased arterial stiffness and pressure imbalance within the framework of preclinical arterio- and atherosclerosis. It is necessary to develop targeted angioprotective measures with СТ and their inclusion in the comprehensive process of managing this category of patients, including in the preoperative period. Therefore, the management of such patients should be based on the principles of effective interdisciplinary cooperation.
Harry, Frodo, and the Religion at the Time of Changes

Published: February 2024

Conflicts between religion and literature are not rare; history can produce many interesting examples of more or less important discussions leading towards prohibitions, burning /of books or authors/, excommunications or imprisonments. Although, in Christian religions and societies consequences of these polemics ceased to be so violent, the vehemence of arguments of the parties concerned is still great. With the publication of J. K. Rowlings' Harry Potter and the revival of Tolkien's Lord of the Rings following Peter Jackson's films, literary critics, religious authorities, psychologists, and many others /re/started the polemics about fantasy literature, and its alleged danger for the souls of believers. On one hand, there is the freedom of the art and artist, on the other, gloomy views of destroyed children, rise of occultism, and threat of paganism. In this paper the author takes a closer look at the arguments of both sides, and considers possible ways of approaching this kind of literature by a religious person of the 21st century.
Late Modern Individualization in Light of Critical Theory (the Frankfurt School): An Essay
Authors: Pieniążek Paweł
Published: February 2024

The article describes the dialectic of the process of individualization in modernity and late modernity from the perspective of critical theory, particularly in its classical form (Frankfurt School). This dialectic consists in the transformation of individualization as a medium of emancipation into individualization understood not only as an ideology but most of all as a productive force of neoliberal capitalism, as a principle of its functioning. The article discusses the social-cultural determinants of this transformation, and subsequently the way in which late-modern individualism in the form of self-realization is functionalized by the market and subjected to the requirements of profit and efficiency in individual areas of economic and social life in the neoliberal world. The article refers to the methodology of qualitative sociology.

Authors: Ivanov Vladimir P. , Timkin Timofey V. , Boldina Daria A. , Pakhtaeva Marina G.
Published: February 2024

Relevance. The problem of studying organometallic compounds in carbonized and carbonaceous substances is a part of the global problem of the structure of natural materials from plant remains and manifestation of ore genesis in organic sedimentary deposits. This problem covers a number of issues. The most pressing one among them is the form of occurrence of finely dispersed gold in the form of organometallic compounds in metal-bearing coals and shales. This is especially true for large gold deposits of black shale strata. Aim. To study the relationship between sedimentation of organic formations and ore genesis in black shale deposits using the example of the Verninskoe deposit (Patom Highlands, Irkutsk Region). Using the SKAUFV hardware and software complex together with ICP-MS and INAA methods, which allow one to assess the degree of Au concentration in organic matter, to substantiate the possibility of determining organometallic compounds of gold that are significant in the processes of sedimentogenesis, lithogenesis and epigenesis. Methods. IR spectroscopy, instrumental neutron activation analysis (INAA) and inductively coupled plasma mass spectrometry (ICP-MS). Results. The authors have determined that the SKAUFV hardware and software complex, together with the ICP-MS and INAA methods, makes it possible to establish the role of organic matter in metasomatism and to identify temperature zonality and the associated gold concentrationin the ore zone. To determine the organometallic compounds of Au, structural and genetic indicators (Pm, Ko, PVt+L, PI) were selected. These indicators reflect the significance of sedimentation, diagenesis, catagenesis and epigenesis on Au concentration in organic matter. These indicators made it possible to assess the level of temperature impact on sedimentary deposits of regional metamorphism and near-ore metasomatism. In this regard, subzones of Au concentration were established in the ore zone, determined by temperature zoning in the form of a manifestation of local metasomatism. The latter was influenced by the protein-fat composition of plants that form organic matter.

Published: February 2024

Relevance. The study of isotopic composition of water and dissolved substances makes it possible to determine not only their genesis, but also the fractionation processes occurring in the “water–rock–gas–organic matter” system over time, i. e. as different stages of the evolution of water composition pass through. Interest in the groundwater of the Arctic regions of Western Siberia is additionally associated with the widespread occurrence of oil deposits at the depths of formation waters and the possible influence of cryogenic metamorphization processes on composition of near-surface waters. Aim. To study and compare the isotopic composition of oxygen, hydrogen and carbon in natural waters of the Yamalo-Nenets autonomous region to identify conditional isotopic markers, as well as to be able to trace the evolution of the isotopic composition of waters along a vertical section in the area of the Taz oil and gas condensate field. Objects. Surface (river, soil and lake), underground waters of the active water exchange zone of the Yamalo-Nenets autonomous region and formation waters of oil and gas deposits of the Taz field. Methods. The study of the isotopic composition of oxygen, hydrogen, and carbon of water-dissolved carbon dioxide was carried out in the Research Equipment Sharing Center at the Institute of Geology and Mineralogy SB RAS using Isotope Ratio Mass Spectrometer FinniganTM MAT 253 equipped with H/Device and GasBench II for sample preparation. Results and conclusions. The paper introduces the data on isotopic composition of O, H and C for natural waters of the Yamalo-Nenets autonomous region. The authors have determined the characteristic trends in changes in the isotopic composition of water and dissolved carbon dioxide for various water bodies. Surface and underground waters with active water exchange in terms of isotopic composition (δD and δ18О) are infiltration. As water moves down the section, with an increase in the time of interaction of the “water–rock” system and increase in temperatures, the isotopic composition becomes significantly heavier with a slope from the GMWL to the right. The authors compiled the diagram of the evolution of water-dissolved carbon isotopic composition in the region according to the obtained and some literature data. Despite the wide range of δ13C values from –30.4 to 23.6 ‰, there are, obviously, only two sources of carbon dioxide in the region: biogenic and atmospheric, with biogenic being predominant for groundwater.

Background: Under the present context of global warming and climate change, the choice of an ecologically hardy crop is having prime importance. Nutrient management is an important approach for improving crop growth and productivity. Among all the nutrients, nitrogen helps in the overall growth of the plant. Nitrogen helps to synthesize chlorophyll and thereby supports building the protein units that enhance plant growth. As nitrogen is highly mobile, it is lost through different ways such as volatilization, leaching, nitrification, etc. Split application of nitrogen through proper scheduling is an important approach to reduce nitrogen loss as well as to improve nitrogen use efficiency. Hence, the investigation was conducted to find out how the scheduling of nitrogen is affecting pearl millet growth and productivity. Methods: The present study was conducted in kharif season of 2022 on pearl millet at Post Graduate Experimental Farm, M. S. Swaminathan School of Agriculture. The experiment was carried out in randomized complete block design with 3 replications and 9 treatments, namely, T1: control, T2: 50% basal RDN, T3: 100% basal RDN, T4: 50% basal RDN + 50% at 30 DAS, T5: 50% basal RDN + 25% at 30 DAS and 45 DAS, T6: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 95%, T7: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 90%, T8: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 85%, T9: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 80%. Result: The results showed that the application of 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 95% gave the maximum growth, yield, and income was also significantly higher with this application. So, it could be recommended to the farmers for growing pearl millet during kharif season in southern Odisha to achieve higher growth and productivity.

Background: Research was conducted to ascertain the impact of hormonal seed strengthening on seed health status under an accelerated ageing test in chickpea (Cicer arietinum L) at the state seed testing laboratory during the Rabi seasons of 2018-19 and 2019-20. Four replications of the Blotter test were performed CRD plan. As per continuous evaluation and observation, under accelerated ageing increased pathogens were observed with increased temperature and RH, the seeds treated with salicylic acid resulted with least pathogen infection while compared to other treatments. Methods: The current experiment was conducted in the state seed testing laboratory, Department of Genetics and Plant Breeding, SHUATS, Prayagraj, Uttar Pradesh, between the years of 2018 and 2020. 37 distinct treatment combinations were employed in the experiment. The seeds were placed in an accelerated ageing condition with high temperature and relative humidity. Hormonal seed strengthening is the activity of infusing PGRs into old seeds to make them fresh again with the help of PGRs (salicylic and giberellic acid) treatments into old seeds and increase the vigour index of seeds. Result: In this experiment chick pea seeds treated with combination of gibberellic acid and salicylic acid resulted in least infection of seed pathogens we can recommend these for maintaining seed health status.

Published: February 2024

Background:Despite much research and many interventions, the opioid epidemic continues to plague the United States. According to the Centers for Disease Control and Prevention (2021), 136 people die daily from both prescription and illicit opioids.Objective:The goal of this pilot quality improvement project is to examine how the implementation of the Opioid Risk Tool (ORT) in clinical practice might impact the beliefs and attitudes of nurse practitioners (NPs) toward prescribing opioid therapy.Methods:A pre–post design was utilized. A convenience sample recruited participants from a private NP Facebook group. The intervention included a prerecorded presentation on the ORT and the use of the ORT for 8 weeks.Results:While 46 NPs completed the presurvey, only 19 NPs completed the postsurvey. Statistical results did not yield significance, but there were several significant clinical trends discovered.Conclusion:Utilizing the ORT to screen for opioid misuse risks has been shown to improve providers’ confidence in opioid prescribing. ORT guides providers in discerning patient risk for developing dependence on opioids.Implications for Nursing:Screening for opioid misuse risk is feasible. ORT adds to the clinical context in deciding a course of treatment in pain management.
Huxley’s Vision of Gender Utopia and the Philosopher-Ruled State in The Brave New World
Authors:   The Criticism and Theory Society of Korea, Cho Hyun June
Published: February 2024

This article examines the vision of gender utopia presented in Aldous Huxley’s Brave New World and explores its utopian possibilities in Mustapha’s World State, which is compared to the philosopher-ruled state in Plato’s Republic. The theme of utopia has been approached differently in liberalism and socialism: liberal utopia prioritizes individual freedom, while socialist utopia emphasizes egalitarian community. The World State in The Brave New World abolishes patriarchy with advanced scientific and technological civilization and depicts a gender utopia without female reproductive labor, emotional labor, and care labor, while the actual main woman characters such as Lenina and Linda suffer pain and death. Therefore, Huxley’s World State represents an ideal gender utopia, while the female characters are evaluated based on their appearance and live tragic lives due to excessive national norms enforcing order. On the other hand, Mustapha’s World State embodies some of the ideal state described in Plato’s Republic, and the two polities are similar in that they are class societies based on stability ruled by philosophers. However, the World State places too much emphasis on community stability, suppressing individual freedom, emphasizing sensual pleasure rather than spiritual happiness, Eudaimonia of Plato’s polity. Eventually, Huxley’s utopia has an ideal structure of gender equality, but the women living there are not so happy. Although it is excellent in terms of stability and efficiency as an ideal politeia ruled by a philosopher, it has limitations that its educational method is rather oppressive, only indulges in pleasure, then represents a failed gender utopia in the end.
