Published: December 2024

Industri batik tulis merupakan batik yang pembuatannya sepenuhnya menggunakan tangan dengan menggunakan canting sebagai alat utamanya. Permasalahan yang terdapat pada industri ini yaitu pada salah satu stasiun kerja mencanting. Pada saat melakukan proses mencanting postur kerja tidak ergonomis dikarenakan pekerjaan tersebut dilakukan secara manual dengan postur kerja yang dengan menonton dan posisi sikap badan duduk, jongkok dan postur canggung dimana postur lengan, kaki, dengan lutut bertumpu di lantai serta postur badan membungkuk saat melakukan mencanting di kain. Hal tersebut dilakukan secara berulang-ulang selama kurang lebih 7 jam kerja. Berdasarkan kuesioner NBM, pekerja sering mengalami keluhan rasa sakit seperti nyeri pada daerah tulang belakang, pinggang, punggung, leher hingga kaki. Penelitian ini bertujuan untuk melakukan analisis keluhan MSDs dengan menggunakan NBM dan metode REBA. Berdasarkan hasil perhitungan NBM yaitu risiko sedang, perlunya dilakukan intervensi dan hasil perhitungan REBA didapatkan rata-rata tingkat risiko pada pekerja di stasiun mencanting adalah tinggi, yaitu harus segera dilakukan perbaikan, akhir skor metode REBA tertinggi pada pekerja dengan level nilai didapat yaitu 3 dengan rata-rata resiko yang cukup besar, sehingga diperlukan tindakan perbaikan. Untuk meminimalisir terjadinya keluhan MSDs maka diusulkan perbaiki postur kerja yang sudah disesuaikan dengan pendekatan ergonomis dan penilaian REBA atau postur yang sudah diukur sesuai postur tubuh yang benar dan tegak saat bekerja.

Bowel preparation before colonoscopy: Consequences, mechanisms, and treatment of intestinal dysbiosis
Authors: Zheng Ze-Long , Zheng Qing-Fan , Wang Li-Qiang , Liu Yi
Published: December 2024

The term “gut microbiota” primarily refers to the ecological community of various microorganisms in the gut, which constitutes the largest microbial community in the human body. Although adequate bowel preparation can improve the results of colonoscopy, it may interfere with the gut microbiota. Bowel preparation for colonoscopy can lead to transient changes in the gut microbiota, potentially affecting an individual’s health, especially in vulnerable populations, such as patients with inflammatory bowel disease. However, measures such as oral probiotics may ameliorate these adverse effects. We focused on the bowel preparation-induced changes in the gut microbiota and host health status, hypothesized the factors influencing these changes, and attempted to identify measures that may reduce dysbiosis, thereby providing more information for individualized bowel preparation for colonoscopy in the future.
Exploring gut microbiota as a novel therapeutic target in Crohn’s disease: Insights and emerging strategies
Authors: Qiao Tong , Wen Xian-Hui
Published: December 2024

Extensive research has investigated the etiology of Crohn’s disease (CD), encompassing genetic predisposition, lifestyle factors, and environmental triggers. Recently, the gut microbiome, recognized as the human body’s second-largest gene pool, has garnered significant attention for its crucial role in the pathogenesis of CD. This paper investigates the mechanisms underlying CD, focusing on the role of ‘creeping fat’ in disease progression and exploring emerging therapeutic strategies, including fecal microbiota transplantation, enteral nutrition, and therapeutic diets. Creeping fat has been identified as a unique pathological feature of CD and has recently been found to be associated with dysbiosis of the gut microbiome. We characterize this dysbiotic state by identifying key microbiome-bacteria, fungi, viruses, and archaea, and their contributions to CD pathogenesis. Additionally, this paper reviews contemporary therapies, emphasizing the potential of biological therapies like fecal microbiota transplantation and dietary interventions. By elucidating the complex interactions between host-microbiome dynamics and CD pathology, this article aims to advance our understanding of the disease and guide the development of more effective therapeutic strategies for managing CD.

Authors: Christodoulidis Grigorios , Agko Sara E , Kouliou Marina N , Koumarelas Konstantinos E , Zacharoulis Dimitris
Published: December 2024

Autoimmune enteropathy (AIE) is a rare immune mediated disorder primarily affecting children, characterized by chronic diarrhea, malabsorption, vomiting, weight loss and villous atrophy. It has also been observed in adults presenting diagnostic and treatment challenges due to its overlap with other gastrointestinal disorders such as celiac disease. Initial diagnostic criteria for AIE include small bowel villous atrophy, lack of response to dietary restrictions, presence of anti-enterocyte antibodies, and predisposition to autoimmunity without severe immunodeficiency. Refined criteria emphasize characteristic histological findings and exclusion of other causes of villous atrophy. AIE is associated with various autoimmune disorders and can present with overlapping features with Celiac disease, including villous atrophy but without significant intraepithelial lymphocytosis. Treatment primarily involves immunosuppression using corticosteroids, calcineurin inhibitors, and anti-tumor necrosis factor therapy, alongside nutritional support. Despite the challenges, understanding AIE’s diverse manifestations and improving diagnostic criteria are essential for effective management and improved patient outcome. Further research is needed to elucidate the pathogenesis, disease progression and long-term outcomes of AIE.

Authors: Kuizinaitė Evelina
Published: December 2024

Cukrinis diabetas – tai lėtinė medžiagų apykaitos liga, pasižyminti padidėjusiu gliukozės kiekiu kraujyje. Ši būklė išsivysto dėl kasos nesugebėjimo gaminti pakankamai insulino arba dėl visiško jo sekrecijos sutrikimo, o tai sukelia angliavandenių, baltymų ir riebalų apykaitos sutrikimus. Pagrindinis cukrinio diabeto gydymo tikslas – hiperglikemijos kontrolė ir ūminių bei ilgalaikių komplikacijų, tokių kaip makrovaskulinės ir mikrovaskulinės ligos bei kitos ilgalaikės cukrinio diabeto sukeltos negalios, prevencija. Mityba yra esminė cukrinio diabeto valdymo dalis. Siekiant kontroliuoti glikemiją, svarbu atsižvelgti į sveikos ir tvarios mitybos rekomendacijas, maisto produktų glikeminį indeksą ir krūvį, taip pat pradėti vartoti priešuždegiminius maisto produktus, įtrauktus į Viduržemio jūros dietą. Insulino dozes rekomenduojama derinti pagal suvartojamų angliavandenių kiekį, vadovaujantis Amerikos diabeto asociacijos mitybos gairėmis. Cukrinio diabeto kontrolė kelia iššūkių ne tik sergančiajam, bet ir jo šeimos nariams. Nors 1 tipo cukrinis diabetas dažniausiai diagnozuojamas vaikystėje arba jaunystėje, šeimos narių įsitraukimas ir vieningas požiūris į mitybą yra esminiai veiksniai, padedantys veiksmingai valdyti ligą.

Introduction. Sleep disturbances are commonly observed in dementia, affecting between 25% and 80% of patients. These disturbances can significantly impact patient behavior and quality of life, as well as increase caregiver burden. This study aimed to investigate the prevalence and correlates of sleep disturbances among dementia patients, focusing on demographic and clinical variables. Methods. A retrospective analysis was conducted on 196 dementia patients from the “Memory Center” at “Prof. Dr. Al. Obregia” Clinical Psychiatry Hospital. Data were collected on sleep disturbances, dementia subtype, demographics, comorbidities, cognitive function, and medication use. Statistical tests were used to assess correlations between sleep disturbances and clinical factors. Results. 29% of the dementia patients exhibited sleep disturbances. No significant association was found between sleep disturbances and dementia subtype, age, gender, or urban-rural residence. However, traumatic brain injury and anxiety were significantly associated with sleep disturbances, with odds ratios of 4.47 and 2.87, respectively. Benzodiazepines and trazodone were commonly prescribed to manage sleep disturbances in the studied population, reflecting their frequent use in addressing this issue. Conclusion. Sleep disturbances in dementia patients are prevalent and may be exacerbated by factors like traumatic brain injury and anxiety. While pharmacologic interventions, including benzodiazepines and trazodone, are widely used, their impact on cognitive outcomes warrants further investigation.

Microfluidic technologies and nanofluids represent a synergistic combination with significant potential for enhancing heat transfer and thermal management applications. This study investigates the thermal and flow characteristics of a 0.001 wt.% alumina (Al₂O₃)-water nanofluid within a custom-designed serpentine microfluidic channel. The nanofluid was prepared and characterized for its thermal conductivity, viscosity, specific heat, and density. Experimental microfluidic studies, supplemented by numerical simulations, were conducted to evaluate the fluid's behavior under controlled conditions. Results indicated a slight increase in thermal conductivity for the Al₂O₃ nanofluid compared to pure water, with increments ranging from 0.16% at 20°C to 0.30% at 80°C, attributed to enhanced Brownian motion of the nanoparticles. Viscosity measurements revealed marginal increases, suggesting minimal impact on fluid flow dynamics. The microfluidic experiments demonstrated a consistent pressure gradient and laminar flow regime, essential for precise control and efficient thermal management. Temperature contours showed effective heat dissipation, with a steady thermal gradient from the inlet to the outlet. The study concludes that low-concentration Al₂O₃ nanofluids can enhance thermal performance in microfluidic systems without significantly affecting flow characteristics, making them suitable for applications requiring efficient heat dissipation, such as electronic cooling and chemical reactions. These findings provide a foundation for future research into higher nanoparticle concentrations and different base fluids, aimed at optimizing the thermal and flow properties of nanofluids in microfluidic environments. The integration of nanofluids with microfluidic technologies holds promise for advancing the performance and reliability of next-generation thermal management systems.

When a person infected with the virus releases aerosol including the virus by sneezing or talking, the virus stays in atmosphere for a long time. If other persons inhale the virus, the person maybe infected. In our previous researches, in order to decrease efficiently the risk of infection, various indoor ventilation conditions have been evaluated by analyzing transport process of the virus concentration using Computational Fluid Dynamics (CFD). From them, it was found that indoor ventilation condition can be optimised by evaluating amount of the virus concentration and residence time. However, the infection process in air way and vascular when these airborne viruses from indoor air is inhaled has not been elucidated yet. In this research, a couple analysis from nasal cavity to cerebral artery via organ is tried to be applied in order to analyze the transport process of virus concentration from nasal cavity to cerebral artery. In addition, the effect of breathing waveforms and virus proliferation on the virus infection is evaluated. Regarding the methods, 3D CAD model of these three parts is created. Continuity equation, Navier-Stokes equation and transport equations of virus concentration are used as the governing equations. The transport equations in the organ is modified with the virus proliferation. Inlet boundary conditions in the nasal cavity are set up to be four types of breathing waveforms. A boundary condition between the nasal cavity and the organ is continuity of virus concentration at the contact surface. Similarly, the other boundary condition between the organ and the cerebral artery is continuity of virus concentration. As results, it was found that the virus concentration in the cerebral artery in case of sinusoidal breathing waveform with long period is the smallest. It was also found that the virus concentration in the organ and the cerebral artery in case of proliferation within the organ is higher than that has no proliferations. It is concluded that a method for minimalizing risk of virus infection can be proposed by the couple analysis.

Published: December 2024

Background: Myofascial release (MFR) is a form of massage therapy that involves identifying and releasing restrictions in the fascia and muscles. MFR-like techniques have shown improvement in abdominal pain, distention, constipation, and quality of life (QoL) in adults. Therefore, MFR may be helpful in patients with irritable bowel syndrome (IBS), a disorder of gut-brain interaction or functional gastrointestinal disorder, mainly presenting with prolonged abdominal pain, bloating, and altered defecation patterns, leading to impairment in QoL. Treatments for IBS are limited and do not always completely relieve pain. To date, no studies have evaluated the feasibility and acceptability of MFR for children with IBS as a potential therapy.
Purpose: The aim of the study is to assess the feasibility and acceptability of administering abdominal wall-targeted MFR in children with IBS.
Setting: This study was approved and conducted at Children’s Hospital of Philadelphia.
Participants: Males and females aged 13–18 years meeting Rome IV criteria for IBS were included in the study.
Research design: Participants underwent six 1-h weekly sessions of abdominal wall-targeted MFR with a licensed massage therapist (LMT) and performed self-MFR at home between sessions. Feasibility and acceptability data were collected via REDCap (Research Electronic Data Capture) by the study team and LMTs. Symptoms and QoL were assessed before and after the intervention period using child and parent versions of validated pediatric questionnaires.
Results: Of 10 participants aged 14–18 years, 60% females underwent the MFR intervention and completed the 6-week protocol. The median visit compliance with questionnaire completion was 90%. All participants received self-MFR education and performed self-MFR between sessions. Fascia restrictions were identified and released in all participants, as reported by the LMTs. Most participants voluntarily provided positive feedback on MFR. All participants reported no or minimal soreness during or after MFR, and no adverse events were reported.
Conclusions: Abdominal wall-targeted MFR is feasible to administer and well accepted in pediatric IBS patients.

L’affrontement entre le capitalisme vert et les alternatives écosocialistes est plus que jamais tangible, et peut s’interpréter comme la confrontation entre une tentative d’intégration des « valeurs » de la nature au mode d’accumulation capitaliste d’une part, et une résistance à l’ontologie marchande, à son rythme, à sa rationalité de l’autre. Dans cet article, l’autrice revient sur les racines de cette opposition, à partir du débat sur le calcul socialiste opposant notamment Otto von Neurath et Hayek, en le mettant aussi en regard des tentatives néoclassiques de modélisations des risques et coûts du désastre écologique, avec le cas emblématique de Nordhaus. À partir de la notion d’incommensurabilité, la possibilité d’une planification écologique postcapitaliste et non technomanagériale est discutée, en articulation avec les apports des théories écoféministes sur l’impératif de réévaluation économique.
Textes venus du vide : Le Prince et que faire ?
Authors: Sibertin-Blanc Guillaume , Samaddar Ranabir
Published: December 2024

Qu’est-ce qui relie Le Prince de Machiavel et Que faire ? de Lénine, que près de quatre cents ans séparent ? Le premier est un recueil de formulations sur ce que doit être un prince, les pièges rencontrés sur le chemin de sa réussite, la manière de gouverner, les indices de son pouvoir et ce qui est nécessaire pour inciter le peuple à contribuer à la gloire d’un royaume princier. Le second, écrit à l’époque de la Révolution russe, traite de la construction d’un parti révolutionnaire, de l’union d’une idéologie et d’une classe, et de la manière dont un parti politique peut devenir un tribun du peuple. Les contextes comme les situations sont très différents. Pourtant, il existe un lien étrange entre les deux. Tous deux ont la qualité énigmatique d’être intemporels tout en étant entièrement axés sur les problèmes de l’époque. Tous deux résonnent avec des préoccupations qui partagent des bases similaires. Tous deux touchent la grande question de la contingence et de l’incertitude. Ils semblent ne pas avoir de filiation. Comme s’ils étaient sortis du vide.
Dialectique, politique et ontologie chez Antonio Negri
Authors: Spagnuolo Marco , Ciccarelli Roberto
Published: December 2024

Antonio Negri a affirmé la nécessité d’un retour à la dialectique pour faire face à « l’usurpation de la critique », opérée d’ailleurs aussi par une certaine interprétation de l’École de Francfort où le rapport au pouvoir et au Capital est pensé comme domination absolue. Cet essai suit les développements du rapport problématique entre l’exigence de la dialectique et le projet ontologique, qui a caractérisé la deuxième partie de l’œuvre de Negri à partir de 1981. L’hypothèse de travail est que, malgré les contradictions induites par le rapport entre ontologie et politique, la reformulation du marxisme en tant qu’ontologie de la production a permis à Negri de repenser la praxis politique et de nourrir une pensée de la révolution au moment où son impossibilité était déclarée par le néolibéralisme.
Sex and work centrality among European employees: The role of gender ideology and the social norm to work
Authors: Coron Clotilde
Published: December 2024

L’abondante littérature sur les différences genrées en matière de centralité du travail n’est pas encore parvenue à un consensus. Les recherches antérieures ont tenté d'expliquer les variations de centralité du travail selon le sexe en se fondant sur la situation professionnelle actuelle de l'individu. Cependant, la centralité du travail est liée à d'autres ensembles de croyances ou de représentations, et dépend également des cultures nationales. Cette étude vise à mesurer les relations entre la centralité du travail, le sexe, l'idéologie du genre et la norme sociale du travail chez les salariés européens. En utilisant des équations structurelles sur l’enquête European Values Study (EVS) de 2017, il est démontré qu'une fois la norme sociale du travail et l'idéologie du genre contrôlées, il n’y a pas d'effet direct du sexe sur la centralité du travail, ni d’effet indirect par le biais de la norme sociale du travail. En revanche, l’idéologie du genre a un effet sur la norme sociale du travail, qui à son tour influence la centralité du travail.
L’énergie nucléaire : un bel avenir ?
Authors: Meyer Teva
Published: December 2024

Les capacités nucléaires installées dans le monde pourraient doubler d’ici à 2050. Près de la moitié des réacteurs en cours de construction se trouvent en Chine. Cette poussée du nucléaire s’inscrit sur fond de compétition commerciale et de tensions stratégiques. La Russie est un acteur important de ce secteur, exportant des centrales nucléaires dans plusieurs pays, mais depuis le déclenchement de la guerre en Ukraine les pays occidentaux cherchent à réduire l’influence de Moscou dans ce domaine.
De l’inégalité des revenus dans le sport professionnel
Authors: Feuillet Antoine
Published: December 2024

La question des inégalités de revenus dans le sport professionnel est dans l’esprit général focalisée sur les revenus des athlètes. Cette question découle des inégalités de revenus au sein du secteur (entre sports) et au sein des organisations d’un sport (entre équipes). Les inégalités de revenus entre athlètes peuvent être expliquées par différentes théories économiques du marché du travail. Ici, les théories des Superstars et du Winner-takes-all sont mobilisées.
« Equal play, equal pay ? »Pourquoi les footballeuses gagnent moins que les footballeurs
Authors: Duhautois Richard , Arrondel Luc
Published: December 2024

Les revendications des footballeuses, notamment les joueuses américaines de « soccer », sur l’égalité de traitement avec les footballeurs, n’ont été satisfaites qu’au niveau des équipes nationales. L’équation Equal play, equal pay dans les championnats est loin d’être aussi simple à résoudre et, malgré des raisons liées à l’histoire du football féminin, s’explique aussi par son économie.
Les clubs amateurs face aux défis du financement : entre inégalités économiques et place croissante du privé
Authors: Hao Li Si , Chenard Antonin
Published: December 2024

Là où les clubs professionnels ajustent la performance sportive (masse salariale, transferts, infrastructures) selon la performance économique (droits télévisuels, billetterie, primes de compétition), les clubs amateurs cherchent à l’inverse à trouver des financements compatibles avec leurs coûts, ce qui les distingue aussi des autres associations. La faiblesse de leurs revenus directs (adhésions, revenus des compétitions, billetterie) et leur rôle essentiel pour la santé publique, l’éducation et la vie locale légitiment le soutien des pouvoirs publics. Les subventions publiques ont cependant diminué ces dernières années, poussant les clubs amateurs à faire évoluer leur modèle économique.
Le sport comme levier d’intervention sociale : enjeux locaux et défis politiques dans les municipalités françaises
Authors: Lessard Coralie
Published: December 2024

Des dynamiques se développent autour de l’objectif de constitution d’un patrimoine socio-sportif, participant à l’héritage des Jeux olympiques et paralympiques 2024 (JOP). Mobiliser le sport au service d’enjeux politiques et sociaux n’est pourtant pas récent : des études sociologiques dressent en effet un panorama de l’évolution de cet usage. Initialement, le monde de l’animation culturelle était hostile au sport, puis en adopte progressivement des approches « sociales ». L’étude menée au sein de directions municipales de la jeunesse et/ou des sports montre que la nature de ces approches est dépendante des orientations politiques. Cet article alerte sur de possibles effets pervers d’orientations voulues sociales, mais qui n’intègrent pas dans leurs principes l’objectif de mixité sociale.
A transformer-driven framework for multi-label behavioral health classification in police narratives

Transformer-based models have shown to be highly effective for dealing with complex tasks in a wide range of areas due to their robust and flexible architecture. However, their generic nature frequently limits their effectiveness for domain-specific tasks unless significantly fine-tuned. We understand that behavioral health plays a vital role in individual well-being and community safety, as it influences interpersonal interactions and can significantly impact public safety. As a result, identifying and classifying these cases demands the use of an effective tool, such as a framework, that has been fine-tuned to context-specific behavioral health issues. In this work, we demonstrated a trainable lightweight approach for addressing behavioral health analysis utilizing feature embeddings generated from transformer-based models. To facilitate in domain adaptation, we created instruction sets based on annotations by subject matter experts, enabling for targeted fine-tuning of the large language model (LLM) for behavioral health applications. Our experiments demonstrated that parameter-frozen transformer-based models can capture high-quality feature representations that allowed for the integration of a lightweight framework, making them especially useful in resource-constrained settings.
