Authors: Belsky R. A. , Frolov V. Y. , Zhiligotov R. I. , Safonov E. P.
Published: September 2024

THE PURPOSE of the study is to study the problem of switching overvoltages in 10 kV generator networks. Using the Matlab Simulink package, create a model of common auxiliaries of a 10/0.4 kV power station, calculate the overvoltage at different sections of the current, evaluate the effect of vacuum switches on each other, evaluate the effectiveness of nonlinear overstrain limiters, with parallel switching.

THE SCIENTIFIC SIGNIFICANCE consists in obtaining a method for calculating transients with simultaneous switching of several switches. THE PRACTICAL SIGNIFICANCE lies in the possibility of using the resulting model for a more accurate selection of protective equipment.

METHODS. To create a model of common auxiliaries of 10/0.4 kV and the calculations of transition processes, it used a Matlab Simulink package. RESULTS. The article discusses switching overvoltages in their own needs of 10/0.4 kV. The influence of parallel switching of vacuum circuit breakers on the increase in the multiplicity of overvoltages is estimated. The influence of the specific energy intensity of nonlinear surge limiters on the multiplicity of overvoltages was also evaluated.

CONCLUSION. This model showed that the parallel switching of two vacuum circuit breakers can increase the frequency of overvoltage by 20-40 %, which can lead to an increase in wear of both insulation of the protected equipment and the probability of re-breakdown in a vacuum chamber. Moreover, the higher the current cut, the higher the increase in the frequency of the overstrain, the multiplicity will also increase if the shutdown time between the switches is reduced. The main means of protection against switching overvoltages is a non -linear overstrain limiter, but when they are selected, the nominal working voltage is primarily taken into account, which leads to the fact that the increase in the frequency of overstrain from parallel switching can level the effectiveness of a nonlinear limiter.

Salah satu upaya meningkatkan hasil belajar matematika adalah dengan memahami kemampuan komunikasi matematis siswa. Hal tersebut dapat dioptimalkan apabila guru mengetahui pula jenis gaya belajar yang dimiliki oleh siswa. Cara lain adalah dengan menerapkan pembelajaran yang sesuai, diantaranya adalah model pembelajaran matematika realistik. Berdasarkan hal tersebut, dilakukan penelitian untuk menganalisis kemampuan komunikasi matematis siswa yang ditinjau dari gaya belajar melalui pembelajaran matematika realistik. Jenis penelitian ini adalah penelitian kualitatif dengan jumlah subjek 44 siswa XI MIA 2 MAS SIMBANGKULON. Teknik pengumpulan data yang digunakan adalah angket, tes, dan wawancara. Hasil penelitian ini menunjukkan bahwa persentase kemampuan komunikasi matematis yang paling dominan pada gaya belajar visual, auditorial, read/write dan kinestetik adalah pada indikator ketiga, yaitu mengungkapkan ide-ide matematis dalam menyelesaikan permasalahan sehari-hari. Dilain pihak, penyebab kesulitan siswa dalam berkomunikasi matematis adalah bervariasi, tetapi yang paling dominan untuk setiap kelompok gaya belajar adalah sama, yaitu kekurangtelitian.
One of the efforts to improve mathematics learning outcomes is to understand students' mathematical communication skills. This can be optimized if teachers also know the types of learning styles that students have. Another way is to apply appropriate learning, including the realistic mathematics learning model. Based on this, a study was conducted to analyze students' mathematical communication skills in terms of learning styles through realistic mathematics learning. This type of research is qualitative research with the number of subjects 44 students XI MIA 2 MAS SIMBANGKULON. The data collection techniques used were questionnaires, tests, and interviews. The results showed that the most dominant percentage of mathematical communication skills in visual, auditorial, read/write and kinesthetic learning styles was in the third indicator, namely expressing mathematical ideas in solving everyday problems. On the other hand, the causes of students' difficulties in communicating mathematically are varied, but the most dominant for each learning style group is the same, namely lack of rigor.
Комедия на слёзном фоне: интерференция катарсисов в пьесе Л.С. Петрушевской «Квартира Коломбины»
Authors: Кубасов Александр
Published: September 2024

Der Artikel wirft die Frage der Katharsis in der modernen Dramaturgie als eine komplexe und vieldeutige ästhetische Reaktion des Lesers auf. Der Begriff „Katharsis-Interferenz” wird in dem Sinne eingeführt, dass die Kombination von zwei Arten der Katharsis – Lachen und Weinen – einen synergetischen Effekt erzeugt, der beide Reaktionen verstärkt. Die eingeführte Definition wird am Material der Analyse von Petruschewskajas Einakter „Colombinas Wohnung” überprüft, der als Modell der philosophischen Farce anerkannt ist. Es wird festgestellt, dass in der zeitgenössischen Dramaturgie an die Stelle der reinen Tränen- und Lachkatharsis deren reduzierte Ableitungen getreten sind. Offenes Lachen wird durch Ironie ersetzt und Tränen durch Gefühle der Bitterkeit oder des Bedauerns. Das analysierte Stück gilt als Modell für ein modernes Metadrama. Es verwendet nicht nur die traditionellen Figuren der Commedia dell’arte (Arlecchino, Pierrot und Colombina) in einer neuen Zeit und einer neuen Umwelt, sondern auch die Kunsttechnik des Puppentheaters und die Realien des sowjetischen Kindertheaters. Das Lachen, welches das ganze Stück begleitet, wird am Ende durch die bitter-ironische ästhetische Reaktion der Leser aufgehoben, die aus Mitgefühl mit den komischen Figuren entsteht. Sie legen sich übereinander, und schaffen das, was man die Interferenz der Katharsis nennt.

Pledge Salience: A Scoping Review of a Non-consensual Concept
Authors: Tremblay-Antoine Camille , Cadieux Hubert , Dufresne Yannick , Cloutier Adrien
Published: September 2024

New innovative tools, named campaign pledge evaluation tools (CPET), are tracking candidates' pledges during electoral campaigns and follow their completion once politicians are elected. Previous researches have observed that all tools treat each pledge equally and have recommended developing a weighting based on the importance of these promises. This research aims to systematically analyze the academic literature on salience in order to identify the measures used to analyse pledges' salience. A scoping study was deployed and extended to the literature on issue salience. Results demonstrate that no consensus has been reached regarding how political scientists measure pledge or issue salience. Depending on the research, the concept is operationalized as salience in news media, political arena, public opinion, experts' assessments or lobbyists' actions using multiple different indicators, which is not problematic in itself, but remains an issue as these studies do not take each other results into consideration. The results therefore call for an empirical test of the reliability of these different measures.
Delaying reward feedback does not increase the influence of information on attentional priority in visual search
Authors: Chow Julie , Garner Kelly , Pearson Daniel , Theeuwes Jan , Le Pelley Mike
Published: September 2024

Rapid attentional capture is shaped by experiences of reward uncertainty: in a visual search task, distractor stimuli that signal uncertain rewards are more likely to capture attention than stimuli that provide diagnostic information about upcoming reward. This pattern of uncertainty-modulated attentional capture (UMAC) runs counter to claims that information-seeking—the drive to identify and exploit sources of predictive information—represents a primary driver of attentional prioritisation. We investigated the possibility that failure to find evidence of information-seeking in prior studies of UMAC was a consequence of immediate provision of reward feedback, negating the value of advance information. In two experiments, we used eye-tracking to examine whether increasing the duration of uncertainty (and hence the potential value of advance information) would promote a pattern of information-seeking in attentional capture. Experiment 1 revealed a general effect of response–feedback delay on the likelihood of capture by salient distractors, but no effect on prioritisation of information: regardless of delay, participants prioritised the noninformative distractor over the informative distractor. Experiment 2 found a similar pattern regardless of whether the delay occurred before or after reward feedback. These findings challenge the idea that information-seeking represents a universal drive for attention, and instead support the idea that—under some conditions—prioritisation can reflect the operation of an ‘attentional exploration’ process that acts to highlight the unknown.

Neuroscience provides researchers with a tools to examine psychological processes behind information processing important to political communication that cannot be measured by self-report or observational methods. This entry describes neuroscience and cognition methods (e.g. fMRI, EEG, eye-tracking) that can be beneficial for political communication research as well as their usefulness for different types of communication (e.g. visual, verbal, interpersonal). We also discuss how neuroscience can be used in substantive areas rapidly growing in importance, such as misinformation.
Nuovi orizzonti Psico-Tecnologici: l'integrazione di Realtà Virtuale e Realtà Aumentata nel trattamento delle Psicopatologie e delle Fobie
Authors: Costanzo Tiziano
Published: September 2024

Questo lavoro esplora le potenzialità dell'integrazione tra scienze psicologiche e tecnologiche, con un focus particolare sull'uso della Realtà Virtuale (VR) e Aumentata (AR) nel trattamento delle psicopatologie, in particolare fobie e disturbi d'ansia. Attraverso riflessioni personali e speculative, l'articolo propone un approccio innovativo basato sulla neuroplasticità multisensoriale e sulle tecnologie predittive, suggerendo che VR e AR non siano semplici strumenti di supporto, ma possano diventare elementi attivi nel rimodellamento delle risposte patologiche attraverso la manipolazione controllata delle esperienze immersive. Vengono affrontate anche le implicazioni etiche e psicologiche legate a un uso prolungato di queste tecnologie, ponendo l'accento sulla necessità di un uso consapevole per evitare rischi di dipendenza o desensibilizzazione emotiva. Si auspica che il presente lavoro offra spunti di riflessione per la comunità scientifica e stimoli lo sviluppo di ricerche specifiche su queste tematiche, favorendo una sinergia tra psicologia e tecnologia per affrontare le sfide future della salute mentale.
Disentangling Sadism from schadenfreude as traits using latent construct modeling
Authors: Parton Drew M. , Chester David
Published: September 2024

Sadism represents a predisposition towards enjoying the suffering that an individual causes to others. However, this conceptualization of Sadism closely abuts that of schadenfreude—finding pleasure in others’ suffering. The relationship between trait Sadism and trait schadenfreude has gone understudied. Using exploratory and confirmatory latent construct modeling with a cross-sectional and diverse sample of 314 undergraduate participants, we found that the bi-factor model of Sadism and schadenfreude that best fit the data articulated Sadism as a sub-facet of schadenfreude. However, an EFA did not find the same relationship, and instead suggested a four-factor solution that split harm-enjoying traits into higher order Sadism and schadenfreude domains that each had lower-order facets—including a malicious component of schadenfreude that most closely abuts Sadism. Future research should seek to identify the mechanisms that translate a passive, schadenfreudic disposition into actual acts of Sadistic aggression.
Lullaby and Affective Touch Tempo: A Comparative Study of Soothing Behaviours
Authors: Rieger Benjamin , Fairhurst Merle Theresa , Abra Yasemin
Published: September 2024

This study investigates the tempo of lullabies and love songs across different cultures to explore their potential universal features and underlying biological functions. By comparing the tempo of these song types in a cross-cultural context, the research seeks to uncover whether these musical forms, particularly lullabies, share a biologically embedded function in regulating emotions and fostering social bonds. The study further explores the interplay between music and affective touch, hypothesising that these caregiving behaviours may be functionally coupled through temporal synchrony. Utilising experimental data and repository data from various continents, the research examines tempo variances and their alignment with the optimal tempo for affective touch, contributing to a broader understanding of music's role in infant care and its implications for therapeutic applications. The findings suggest that lullabies exhibit less tempo variance and are generally slower than love songs across cultures, reinforcing their role in soothing and emotional regulation. This research highlights the importance of tempo in music and its potential evolutionary connection to caregiving behaviours, with implications for future studies and practical applications in neonatal care.
Prospective and retrospective awareness of moment-to-moment fluctuations in visual working memory performance
Authors: Kozlova Olga , Adam Kirsten C. S. , Fukuda Keisuke
Published: September 2024

Visual Working Memory (VWM) performance fluctuates from moment to moment with occasional failures in maintaining accurate information in mind. While previous research suggests that individuals are more often overconfident in their VWM performance during these failures, no study to date has examined whether individuals can prospectively predict VWM performance reductions. To test the accuracy of both prospective and retrospective awareness on VWM performance, we developed a VWM bet task in which participants made trial-by-trial bets and confidence ratings on VWM performance. Across two experiments, we demonstrate that retrospective awareness is more sensitive to VWM performance fluctuations than prospective awareness, though both metacognitive abilities are far from perfect. The poor metacognitive abilities reflected a general tendency for individuals, particularly the low VWM capacity individuals, to overestimate their VWM performance. When individuals overestimated their upcoming VWM performance (i.e., prospective failures), we observed a reliable reduction of VWM performance compared to the preceding trials of a prospective failure. Moreover, this reduction in performance lingered into subsequent trials. Interestingly, however, individuals’ prospective and retrospective awareness better aligned to VWM performance after the initial occurrence of a prospective failure. This post-failure calibration was observed even without immediate feedback signaling the occurrence of a prospective failure (Experiment 2), thus suggesting a metacognitive efficiency in recognizing the initial overestimation. Taken together, our results suggest that individuals, particularly low-capacity individuals, have a limited awareness towards upcoming VWM performance. However, after the occurrence of a prospective failure, individuals adjust their metacognitive ratings to better reflect their VWM performance.
A good life full of suffering: Evaluating a life as a whole
Authors: Abe Nozomi , Morita Kunihisa
Published: September 2024

Can a life full of suffering be good? This study might make it possible to answer this question in the affirmative. Participants were shown two scenarios describing two people’s lives: one whose life is full of suffering but meaningful [A] and another whose life is full of pleasure but not meaningful [B]. We asked the participants which life they considered better and which one they would choose to live. The results showed that some participants considered A’s a good life despite being full of suffering. In addition, some considered the suffering necessary for A’s success. Therefore, this can be considered a case of suffering potentially enhancing well-being. Furthermore, our research methodology, presenting concrete life scenarios, provides an objective way to evaluate life as a whole.
Tracking Reactivation of Location Information during Memory Maintenance Strategies: Insights from Eye Movements.
Authors: Bhanap Ruhi , Bartsch Lea Maria , Rosner Agnes
Published: September 2024

Memory maintenance strategies such as visual imagery and rehearsal are widely reported by participants as means to enhance recall and their underlying mechanisms are thought to differ. Visual imagery is believed to engage both visual and spatial aspects of memoranda, while rehearsal is thought to reactivate only the item-specific information, excluding spatial information. In this study, we employed the Looking at Nothing (LAN) effect – in which individuals make eye movements towards the original location of the memorized item during retrieval – to investigate the reactivation of spatial location in both visual imagery and rehearsal. Our findings demonstrate that LAN occurs with both strategies, indicating that spatial information is reactivated during rehearsal as well. Notably, we observed higher immediate as well as delayed memory performance with visual imagery compared to rehearsal. However, the amount of LAN observed for both these strategies remained the same. To further explore whether these differences in the amount of LAN and memory performance were driven by a modulation of the strength of long-term memory (LTM) traces we introduced proactive interference (PI) in a second experiment. PI is known to impact LTM traces, while leaving working memory (WM) intact. While PI led to a decline in WM for visual imagery, the amount of LAN remained the same. These results indicate that visual imagery and rehearsal both reactivate location information and additionally, visual imagery drives eye movements and memory benefits through distinct mechanisms.
Evaluating DDS for Surgical Video Streaming

Published: September 2024

Real-time video in surgery is crucial for: ● providing immediate visual information, ● enabling precise surgical actions, ● aiding in education and collaboration, ● and facilitating post-operative analysis. The ability for surgical systems to transport metadata that is correlated with the video feed is crucial for surgical applications to be more effective, particularly as surgical robotic systems become more intelligent and autonomous. [1] Many streaming protocols are available for video streaming, like the Real-Time Transport Protocol (RTP) and WebRTC, among others. However, these legacy protocols present two challenges: ● They may not be able to satisfy real-time requirements for surgical applications. ● They are specifically designed for media transport only, which makes it difficult or even impossible to transport metadata alongside surgical video. Data Distribution ServiceTM (DDS) is already a popular choice of communications framework for medical robotic systems, and is also the default middleware within ROS2. Consequently, it is worthwhile to evaluate whether DDS is a suitable communication framework for video alongside other data such as control, sensor, or even patient monitor data in a surgical system.

In high-risk high-stakes environments, such as the cardiac operating room (OR), the cognitive processes of each surgical team member, as well as alignments or misalignments between team members play a critical role in team performance and consequent patient care quality. This study's goal was to investigate the cognitive processes of cardiac surgery teams, particularly focusing on the potential misalignment between OR teams during coronary artery bypass grafting (CABG) procedures. We evaluated critical intraoperative cognitive processes, including decision- making, communications, and problem-solving strategies across different phases of CABG procedures, providing quantitative measurements of misalignments within the teams, and reporting the specific phases of surgery that have the highest cognitive process misalignments. By analyzing these cognitive dynamics, our goal is to enhance the understanding of team coordination and cognitive distribution in the operating room. Specifically, by pinpointing where and how cognitive misalignments occur, we can develop targeted interventions. These interventions aim to streamline communication, decision-making, and problem-solving, ultimately contributing to improved patient care in cardiac surgery.

The integration of Artificial Intelligence (AI) into clinical decision support systems (CDSS) marks a significant advancement in the pursuit of enhanced patient care and operational efficiency in high-stakes environments, such as the operating room (OR) [1]. However, the complexity and often "black box" nature of these AI systems pose substantial challenges for human-AI teaming, where explainability is crucial for clinicians to understand and trust the AI's recommendations. The field of explainable Artificial Intelligence (xAI) offers promising methods and techniques to make AI decisions more explainable and interpretable, yet the adaptation of these methods to meet the specific needs of clinicians remains underexplored [2]. Our proposed clinician-centered framework, xAI-SURG, seeks to bridge this gap by aligning xAI approaches with the complex decision- making processes inherent in the OR. By evaluating the xAI-SURG framework through the lens of perfusionists' decision-making during cardiac surgery, we provide a use-case, showcasing the importance of tailored xAI that not only aligns with but also enhances clinician expertise and patient safety and outcomes in the OR.
Variable Stiffness Soft Everting Robot via Temperature Control of Low-Melting Point Alloy Pressurised Medium

The inherent compliance of soft everting (growing) robots permits them to conform to complex pathways and to continually change in shape and configura- tion. Such robots navigate their environments through pressure-driven eversion, whereby a compliant tip un- folds along its pathway (apical extension) [1]. This makes everting robots well-suited for minimally invasive surgery (MIS) applications, such as the MAM- MOBOT, which was developed to identify cancer lesions within the mammary duct [2]. Whilst compliance allows growing robots to navigate fragile human lumen, it limits their effectiveness in interacting with tissue. Due to the use of soft materials, these compliant systems cannot withstand high forces and are unable to sustain their own weight, leading to buckling and reduced capability to deliver high payloads. Surgical tasks, such as biopsies and interventional procedures, however, often require payload delivery and force exertion. Variable stiffness systems aim to combine the benefits of compliance and rigidity in everting and catheter- like robots in general. Variable stiffness approaches have been previously implemented in growing robots via layer jamming and pneumatic expansion. However, to achieve a sufficient stiffness ratio, layer jamming requires a substantial number of layers and pneumatic expansion demands a specific pouch geometry, making miniaturisation to a scale suitable for MIS challenging. An alternative approach is thermoactive stiffening, which functions by applying a thermal energy input to induce a change in phase in materials such as low melting point alloys (LMPA), wax or solder. LMPA approaches have been explored in soft robotic and robotic catheter systems, boasting a stiffness ratio 3⇥ higher than granular jamming and 1.5 � 3⇥ higher than layer jamming [3]. Thermoactive stiffening has not been investigated in growing everting robots, as it is challenging to simultaneously control the temperature, phase and volume of a system that is changing in shape and length as it everts. In this paper, we introduce a steerable, temperature- controlled, LMPA-based variable stiffness everting robot. The performance of the system in soft and rigid state are characterised, and the effectiveness of our approach in delivering clinically relevant forces is demonstrated.

Published: September 2024

Surgical procedures are characterised by specific move- ments of the surgeon’s hands to complete tasks such as suturing, cutting, or object relocation. Understanding the context and kinematics of these procedures can allow us to predict the goal that the surgeon is trying to achieve and provide the correct external guidance. In this paper, we develop a real-time surgical gesture recognition method for shared control in robotic sur- gical tasks. We implement Long Short-Term Memory (LSTM) and Transformers-based methods to verify their performance for real-time applications. To prove the effectiveness of our methods, we evaluate and assess it on an existing dataset. We demonstrate that a high performance can be achieved for real-time recognition of kinematic surgical gestures by categorising the suturing task in four essential surgeme motions (Figure 1) and one for general movements.

Capsule endoscopy, recognized for its convenience, non- invasiveness, and painless approach, has modernized gastrointestinal (GI) diagnostics. This innovative pro- cedure involves patients swallowing a pill-sized device that navigates the GI tract via peristalsis, capturing high-resolution images of otherwise inaccessible areas. Despite its popularity and benefits, capsule endoscopy hasn’t matched the diagnostic and therapeutic potential of traditional endoscopy. This can be attributed to its passive nature, which limits the ability to focus on specific areas, leading to variable procedure times and, in some cases, capsule retention [1]. A solution that has been explored to enhance capsule endoscopy’s capabilities is the use of magnetic manip- ulation to enable active control [2]. However, achieving precise control and real-time localization requires ad- ditional components, in particular a continuous power source. In this context, Wireless Power Transfer (WPT) technology, already successful in powering devices like pacemakers, offers a promising avenue as it can elimi- nate the need for internal batteries. This paper presents the development of a robotically manipulated magnetic capsule system equipped with integrated WPT coils for autonomous power transfer during magnetic manipulation. It introduces a novel approach featuring a transmitter coil mounted onto a robotic manipulator coupled with an internal 3D receiver coil within a tethered capsule (Fig. 1). Subsequent sec- tions delve into the design, implementation, and assess- ment of the magnetically manipulated tethered capsule system, including an autonomous recoupling algorithm and experimental results within a colon phantom.

Published: September 2024

To safely access deeper regions of the brain for proce- dures like tumor resection, surgeons must displace (i.e., retract) healthy tissues usually through the use of rigid, metal spatulas [1]. However, required retraction forces up to 2.5 N have been shown to increase intracranial pressures beyond the safe range of ≈ 2-3.3 kPa and cause neurological complications when applied over sustained durations [1], [2]. Soft robots have shown the potential to address the need for safer access in neurosurgery by leveraging their inherently safe tissue interactions for tasks such as deploying electrocorticography arrays [3] and navigating brain vasculature [4]. However, there remains a need to quantitatively monitor retraction forces so as not to cause injury to healthy brain tissue. In our previous work, we introduced a soft robotic retractor that distributed retraction forces and generated a sur- gical workspace through origami-inspired actuation [5]. Here, we present origami sensing modules (OSM) with the ability to monitor tissue interaction forces of the soft robotic retractor via a capacitive sensing modality (Fig. 1). The OSM folds with the elliptical Miura origami pattern of the robot so that contraction/expansion over vacuum pressures and stiffening over positive pressures can retract tissue while monitoring forces (Fig. 1A). By implementing force sensing into the soft robotic retractor, the proposed OSMs seek to reduce unintended trauma and improve the overall safety of tissue retraction in neurosurgical procedures.
Decolonial Animal Ethics in Linda Hogan’s Poetry and Prose. Towards Interspecies Thriving by Małgorzata Poks (Book Review)
Authors: Lönngren Ann-Sofie
Published: September 2024

Małgorzata Pok’s Decolonial Animal Ethics in Linda Hogan’s Poetry and Prose: Towards Interspecies Thriving (2023) focuses on the relationship between the modern, hierarchical, anthropocentric view of non-human animals, and the traditional, relational view in Indigenous ontologies. In dialogue with human-animal studies, decolonial studies, and traditional ecological knowledge (TEK), the study provides an in-depth engagement with the literary authorship of Chickasaw poet and novelist Linda Hogan. The questions that Poks asks are: What is the significance of Indigenous knowledges for the Anthropocene? How do these knowledges relate to the extinction of species and environmental grief? What insights are offered by Indigenous ethics to activists and decision makers in this regard? Despite the scope of Hogan’s production there is not much written about her literary production, Poks claims, even less so about the representation of the human-animal relationship in it. This is a lack which Poks makes up for in a thorough investigation of Hogan’s prose and poetry from the 1970’s until today. In Hogan’s works, themes like mercy, compassion, wildness, grief, and the connection between femininity and animality are in constant dialogue with the painful story of Indigenous America. Through Hogan’s own experiences in life, her description of places like Oklahoma and Colorado gain both material and metaphorical qualities. This is also the case with the landscapes and the non-human animals who inhabit them and who become agents in their own right in a constant yet shifting and transformative relationship to the human, who is thus decentered in effective ways.
On Voyaging and "Bildung" (The Case of Wellingborough/Redburn)
Authors: Jędrzejko Paweł
Published: September 2024

Paweł Jędrzejko’s reflection on the career trajectories of Americanists from Eastern Bloc countries, including his own, spurs off his autoethnographic account of how sea sailing in Poland became a gateway to the world, leading to his involvement in Melville Studies. His chance encounter with the Polish training ship Zawisza Czarny in the Baltic Sea, marking the beginning of his Americanist journey, becomes a point of departure for a literary analysis, in which the author draws parallels between his own youthful experiences and those of Melville’s character Wellingborough Redburn. Exploring the character’s transatlantic journey in the context of the autobiographical characteristics of the genre of bildungsroman, Jędrzejko analyzes Redburn’s journey from naïve boyhood to mature identity, emphasizing Melville’s use of Redburn’s voyage to Liverpool as a mirror of his own confrontation with reality, the collapse of inherited ideals, and the development of independent self-awareness. The author highlights the importance of direct (unmediated) experience in the shaping of one’s self-awareness, and poses questions concerning the reliability of narratives as “guides to reality.” By reflecting on the transformative nature of travel and the epistemological shifts it entails, Jędrzejko integrates his personal narrative with broader philosophical inquiries into identity formation, the fallibility of inherited knowledge, and the existential challenges faced by individuals in their pursuit of truth. The text serves as a meditation on the fluidity of discourse and the necessity of embracing uncertainty and impermanence as inextricable determinants of the human condition.
Raw Material Supply Control Analysis with Ordinary Least Square Method and Economic Order Quantity (Eoq) at Tandi's Bakery

Published: September 2024

MSMEsTandi's Bakery produces never stop every day. Therefore, inventory control has a very important position. At Tandi's bakery there are often stock outs and the determination of the Reorder Point is erratic. This study aims to determine the number of orders in the next 1 year using Ordinary Least Square (OLS) and to determine the optimal number of orders that must be issued by business actors, to find out when reorders must be made (ROP), and the application of the EOQ and OLS methods in Tandi's Bakery to optimize inventory costs. This type of research is descriptive in terms of data used primary and secondary data in the form of analysis related to the supply of raw materials for bread.
The results showed that the sales of bread in the next 1 year amounted to87,868 pcs of bread according to the OLS method. The optimal purchase amount for Tandi's Bakery raw materials uses the EOQ method in the 2021/2022 period, namely 256 kg of flour, 55 kg of butter and 113 liters of liquid milk while in the previous period 291 kg of flour, 48 kg of butter and 69 liters of liquid milk. The frequency of orders using the EOQ method in the 2021/2022 period, namely 8 times flour, 4 times butter and 6 times liquid milk, while the order frequency for the previous period was 9 times flour, 4 times butter and 4 times liquid milk. The total inventory cost (TIC) using the EOQ method for the 2021/2022 period is as follows: Flour Rp. 255,148, Butter Rp. 135,417 and liquid milk of Rp. 174,006 while the previous period, namely flour, amounted to Rp. 891,032, Butter Rp. 870,670, liquid milk of Rp. 869,954. The exact time to reorder the reorder point (ROP) according to the EOQ method in the 2021/2022 period is 74,909 kg of flour, 8,438 kg of butter and 22,476 liters of liquid milk. In the previous period flour 97.129 kg, butter 6.387 kg and liquid milk 8.998 liters.

El fenómeno de las adicciones trasciende el consumo de sustancias, y comprende una amplia gama de prácticas denominadas como “autodestructivas”. La adicción se presenta bajo diversas formas de dependencia que tienen como común denominador la disminución de la autonomía, las fracturas emocionales y la ruptura de los principales vínculos de quien vive el problema. Las adicciones son un fenómeno de larga data cuyas consecuencias en la actualidad (2024) se asocian con la ruptura del tejido social. Lo cual demanda un cambio en la mirada sobre la problemática que apunte a un acercamiento desde la complejidad y la interdisciplinariedad.
Epílogo. Adicciones, familia y codependencia

En la actualidad (2024), el problema de las adicciones se ha agudizado. Hace algunos años, las drogas no eran tan accesibles como ahora sino que el consumidor tenía que buscar a los contactos, saber quién era el dealer y dónde podía comprarla sin ponerse en riesgo; también se tenía que saber acerca de la calidad y el precio de las drogas; en cambio, hoy en día las drogas se venden casi en cualquier lugar: papelerías, puestos de dulces, chicharrones, palomitas, etcétera. Las nuevas drogas son asequibles para un mayor número de personas que con poco dinero pueden obtener una dosis considerable. Además, el acceso a Internet ha posibilitado encontrar video–tutoriales sobre cómo cocinar la droga en casa para consumo personal.

Acercarse al sujeto adicto desde una mirada compleja significa introducirse en un campo de actores y actorías; asumir que las adicciones no son un asunto de personas aisladas sino una problemática social, de salud, de políticas públicas y de seguridad que implican la dimensión comunitaria, la familiar y personal. Hablar del sujeto adicto demanda acercamientos estructurales, culturales, individuales y subjetivos. A menudo, la comprensión del adicto y de la adicción se caracteriza por ser reduccionista y parcial. El sujeto adicto es un producto social que la misma sociedad silencia, estigmatiza, oculta e invisibiliza. Esta problemática devela e interpela la realidad de una nación. En esencia, el ingreso al consumo de drogas y la adicción representan una búsqueda de identidad, sentido, libertad, pertenencia y, en definitiva, de vida. El sujeto adicto es alguien que buscando la vida ha encontrado la muerte.
Familia y adicciones. ¿Lazos protectores o lazos adictivos?

La realidad latinoamericana, y en particular la mexicana, está marcada por la pobreza, la corrupción, la impunidad, las crisis económicas, la desigualdad social, la exclusión de amplios sectores sociales, la violencia desgarradora, así como la prevalencia y el aumento del alcoholismo y la drogadicción. La pandemia generada por covid–19, que comenzó en marzo de 2020, vino a agudizar los problemas ya existentes: durante la pandemia se generaron cierres de empresas y lugares públicos de educación, recreación, deportivos y de servicios. Asimismo, ante las medidas de confinamiento, se dio la convivencia forzada en las familias la cual ya de por sí era complicada en muchos casos dadas las características antes mencionadas. Los servicios de salud no han sido suficientes, por lo que las familias se han tenido que hacer cargo de solventar gastos médicos y funerarios que no se tenían contemplados; la mortalidad de padres y madres ha dado como resultado el aumento de niños y jóvenes desprotegidos.

O treinamento de pais é fundamental na psicoterapia de crianças e adolescentes. Cabe aos pais/mães/cuidadores manipularem as contingências que atuam sobre comportamentos alvo de crianças e adolescentes em terapia, desse modo, estes também podem ser usuários dos serviços de psicoterapia. É comum em programas de treinamento de pais o uso de estratégias baseadas em controle instrucional, o que pode propiciar a dependência de pais/mães/cuidadores em relação ao psicólogo. A Psicoterapia Comportamental Pragmática – PCP é um modelo de terapia de orientação analítico-comportamental de adultos que se caracteriza por intervenções em que o controle instrucional é evitado, sendo aplicados procedimentos como o questionamento reflexivo. Este artigo descreve como a PCP pode ser aplicada ao treinamento de pais, de modo a favorecer maior autonomia dos pais/mães/cuidadores no desenvolvimento de práticas parentais mais eficazes na criação dos filhos.
Metaplastic breast carcinoma with squamous differentiation: report of nine cases
Authors: Esmaeil Akbaria Mohammad
Published: September 2024

Breast metaplastic carcinomas are a rare form of malignancy that exhibit epithelial and sarcomatoid components, including primary squamous cell carcinoma. Primary breast SCC and tumors with squamous differentiation are subtypes of breast metaplastic cancer. The prevalence of primary squamous cell carcinoma (PSCC) of the breast is estimated to be between 0.06% and 0.2% of all breast cancers, and less than 0.1% of invasive breast cancers. At our Cancer Research Center, we have managed and treated 9 patients with PSCC aged between 24-67, and all of them except one were of reproductive age, out of a total of 4000 breast cancer cases during the last two years.
Associations of Hemodialysis Procedures with Stimulation of Supraventricular Arrhythmias
Authors: Tsukamoto Yusuke
Published: September 2024

Evidence suggests higher mortality after two-day gaps in thrice-weekly hemodialysis, with mortality increases of 20-40%. Supraventricular arrhythmias (SVAs), notably atrial fibrillation, are common during dialysis, increasing mortality risk. Hemodialysis induces fluid, electrolyte, and hemodynamic shifts, precipitating arrhythmias. Investigating these associations is crucial for devising preventive strategies and improving outcomes in haemodialysis patients. Materials and Methods: A Holter 24-hour electrocardiogram (ECG) was recorded in 72 hemodialysis patients starting at the beginning of the first session of the week. The associations between an increase in supraventricular premature contractions (SVPCs) during hemodialysis and peridialytic changes in blood electrolytes, mean arterial pressure (MAP), ultrafiltration volume (UFR/DW), ultrasonic cardiographic (UCG) parameters, and other factors were tested using multiple regression analysis. Patients' backgrounds were also compared among tertiles of 24-hour total SVPC counts. Results: SVPCs increased during hemodialysis and six patients developed atrial fibrillation, and 25% maintained low SVPC rates throughout the recording. Patients in the highest tertile for 24-hour SVPC counts had the lowest body mass index (BMI) and the fewest cardiovascular diseases (CVD). They also had the smallest left atrial (LAD) and left ventricular end-systolic dimensions (LVDs). Multiple regression analysis showed that larger changes in mean arterial pressure (MAP) during dialysis were significantly associated with a higher percentage increase in SVPC in all four models. Smaller LAD and larger ultrafiltration volumes (UFR/DW) were also associated with a percentage increase in SVPC. Conclusions: Larger changes in intradialytic mean arterial blood pressure caused by excessive ultrafiltration may increase the risk of developing SVPCs during hemodialysis, particularly in undernourished patients.
