Authors: Adviana Febry , Ula Shofiatul , Sunardi
Published: January 2025

Adhesive bonding is a technique widely used in various industries to join materials together. This process provides several advantages over traditional mechanical fastening methods, such as welding or nailing, including improved appearance, weight reduction, stress distribution, and the ability to join dissimilar materials. The advantages of adhesive bonding are simpler assembly, lightweight and lower production costs. This research is one of the developments of the glue adhesive connection method. The materials used in this research are 1100 series aluminium and low carbon steel where both are metals that we often encounter in everyday life. This study aims to analyse the effect of roughness treatment on the surface of each different test specimen using sandpaper with different roughness levels, namely 80 grit, 150 grit and 400 grit. The test conducted in this study was a tensile test to determine the maximum strength of the adhesive strength of each test specimen with ASTM D1002 test standards. The results showed that test specimen A with surface roughness treatment using 80 grit had a tensile strength of 0.2267, test specimen B with surface roughness treatment using 150 grit had a tensile strength of 0.168 and test specimen with 400 grit roughness treatment had a tensile strength of 0.0315.

КОРПОРАТИВНИЙ ПОДАТОК, ЯК ПОДАТКОВА ПОЛІТИКА ЩОДО ПРЯМОГО ОПОДАТКУВАННЯ В КРАЇНАХ ЄС
Authors: Лекарь С.І. , Савченко А.М.
Published: January 2025

Податкове законодавство країн ЄС у частині прямого оподаткування є більш простішим завданням, ніж гармонізація непрямих податків, оскільки, у відмінності від непрямого, пряме оподаткування використовувалося в кожній державі-члені ЄС. Європейська комісія зазначала мінімальну ставку корпоративного податку у розмірі 30% для прибутку та розподіленого прибутку в вигляді дивідендів. На другому етапі – 40%. Всі рішення комітету не отримали успіху та були відкликані. Розвиток податкової політики у ЄС максимально пов’язаний із інтеграційними процесами. Стосовно прямого оподаткування, тут є можлива лиш часткова гармонізація, котра б сприяла позитивному функціонуванню внутрішнього ринку ЄС. Загальна гармонізація прямих та непрямих податків позбавляє країни впливу на власні економіки та може бути чинником зниження дохідної бази бюджетів країн, в котрих застосовувались більш вищі ставки податків.
Características dos componentes da classe geral denominada comportamento criativo identificadasa partir da literatura da Análise do Comportamento
Authors:   Universidade Federal de Santa Catarina, Souza Eduardo José de , Kubo Olga Mitsue ,   Universidade Federal de Santa Catarina
Published: January 2025

Investigar o fenômeno “criatividade” a partir da noção de comportamento traz como exigência identificar as características dos componentes da classe geral comportamento criativo. Foram examinadas 20 fontes de informação sobre comportamento criativo na literatura da Análise do Comportamento. O procedimento consistiu em destacar trechos das obras que definiam ou caracterizavam esse comportamento. Os destaques foram organizados segundo categorias referentes a características da classe de estímulos antecedentes, ca-racterísticas da classe de respostas e características da classe de estímulos conseqüentes. Como característica da classe de estímulos antecedentes, é possível afirmar que esta se constitui por estímulos “novos”, cuja relação de controle é “sutil”. A classe de respostas do comportamento criativo é caracterizada por respostas infreqüentes, não emitidas anteriormente. As respostas são denominadas por verbos como “variar”, “ma-nipular”, “associar”, “combinar” e “criar elos”. A classe de estímulos conseqüentes é caracterizada pela utilidade da resposta. Termos como “novo” e “sutil”, são vagos, portanto, insuficientes para se referir ao comportamento criativo de modo mais preciso. Estudos sobre variabilidade comportamental se mostram relevantes para compreender o comportamento criativo sendo que os verbos encontrados para se referir à classe de resposta denotam variação da resposta. A utilidade da resposta é provavelmente uma característica definidora do comportamento criativo.
Efectos del reforzamiento cualitativamente variado sobrela tasa de respuesta en ratas

Published: January 2025

Se compararon los efectos del reforzamiento cualitativamente variado y del reforzamiento constante sobre la tasa de respuesta en una palanca empleando a ratas como sujetos. En el Experimento 1, se expuso a ratas a un programa múltiple de tres componentes durante los cuales se reforzaron las presiones a una palanca conforme a un programa de intervalo variable 60 s. Durante dos componentes de reforzamiento constante, se entregó leche o comida. Durante el componente de reforzamiento variado, se entregó la leche o la comida de manera aleatoria. En el Experimento 2, se condujeron tres tipos de sesiones, durante las cuales estuvo en efecto un programa de intervalo variable 60 s. Durante el primer tipo de sesión, se entregó la leche, durante el segundo tipo se entregó la comida y durante el tercer tipo se entregó la leche y la comida. El orden de las sesiones se eligió al azar diariamente. En ambos experimentos, la tasa de respuesta fue mayor cuando se entregó sólo la leche que cuando se entregaron los reforzadores variados. Se concluyó que las variacio-nes cualitativas del reforzador no necesariamente resultan en aumentos en la tasa de respuesta relativas al reforzamiento constante. El efecto aditivo del reforzamiento variado sobre la tasa de respuesta depende de manipulaciones experimentales específicas.

O presente estudo verifi cou os efeitos da ordem de ensino e da transferência de funções sobre relações ordinais em crianças surdas. Doze crianças surdas foram distribuídas em dois grupos experimentais. No Grupo 1 a tarefa era ordenar os estímulos com base na numerosidade, e em seguida ordenar outros estímulos sem ter por base a numerosidade. No Grupo 2 os participantes eram expostos à ordem inversa. No procedi-mento de ensino informatizado, a tela do computador era dividida em “área de escolha”, onde os estímulos eram apresentados aos pares, e “área de construção”, onde os estímulos eram dispostos lado a lado após a seleção. Respostas corretas produziam uma animação na tela, após completar a seqüência. Caso contrário, a tela escurecia por 2 s. Após revisão da linha de base, eram apresentados testes de transitividade e conec-tividade. Todos os participantes atingiram o critério de acerto e foram capazes de formar novas seqüências, com alguma variabilidade inter e intra-sujeitos. Nos testes de conectividade, os participantes do Grupo 1 apresentaram um responder mais consistente com a linha de base. Houve transferência de funções ordinais para os novos estímulos, demonstrando-se a eficácia do procedimento de sobreposição no estabelecimento de classes de estímulos ordinais equivalentes.
Efeitos de atraso e tarefa na resolução de problemasmatemáticos em crianças com e sem TDAH
Authors:   Centro de Educacional de Catalão, Silva Renata Limongi França Coelho , Coelho Cristiano ,   Instituto de Ensino Superior de Brasília, Silva André Vasconcelos Da ,   Universidade Federal de Goiás
Published: January 2025

Na análise do comportamento, situações de autocontrole/impulsividade têm sido estudadas por meio de situações de escolha com alternativas que diferem em atraso e magnitude do reforço. Oito crianças foram alocadas em um grupo “com TDAH” e seis em um grupo “sem TDAH”. Posteriormente essas crianças foram submetidas a cinco sessões experimentais de resolução de contas de adição e subtração que pode-riam ser realizadas conforme uma de duas tarefas. Como em outros estudos sobre os efeitos do atraso em situações de escolha com humanos, a proporção de escolha entre as tarefas não variou sistematicamente com a manipulação do atraso. Por outro lado, para o grupo “com TDAH”, observaram-se maiores fl utuações na preferência entre as alternativas ao longo das sessões experimentais. Os presentes resultados indicam os cui-dados necessários para se afi rmar que o TDAH envolve autocontrole quando se utiliza escolhas com atraso, além de discutir os problemas em se utilizar este modelo.
Promoção de interações sociais entre colegas e criançaautista em ambiente de inclusão
Authors: Nicolino Victor Faria , Malerbi Fani Eta Korn
Published: January 2025

O objetivo do presente estudo foi verifi car a possibilidade de aumentar a freqüência de interações sociais entre uma criança autista e seus colegas sem problemas de desenvolvimento, através da utilização de um procedimento de modelação ao vivo. Os participantes foram um menino (H), com idade de 5 anos, diagnos-ticado com ASD desde os 3 anos e três colegas da mesma classe (duas meninas e um menino), com idades entre 4 e 5 anos, sem diagnóstico de necessidade especial. A intervenção ocorreu na quinta sessão de obser-vação e consistiu na apresentação de um modelo de interação entre o experimentador (E) e H. Isto ocorreu na presença de todos os colegas durante as duas atividades (atividade que envolve brinquedos e apresentação de tarefas aos colegas). Os resultados evidenciaram que após a observação da interação entre E e H, os três colegas aumentaram a taxa de iniciações sociais dirigidas a H e este aumentou a taxa de respostas a essas ini-ciações em relação à Linha de Base. A taxa de interações entre os colegas e H continuou a crescer até atingir uma estabilidade em torno de 3 iniciações/minuto, mantendo-se nesse nível até o término do procedimento de observação na décima segunda sessão.
As primeiras aprendizagens com estímulos aversivos:considerações iniciais
Authors:   Universidade de São Paulo, Gehm Tauane P.
Published: January 2025

O objetivo deste artigo foi discutir as questões: (1) Quando começam as primeiras aprendizagens envolven-do estímulos aversivos?; e (2) Como são essas aprendizagens? Para tanto, foram analisados estudos experi-mentais com diferentes espécies, incluindo-se humanos, que se debruçaram sobre aprendizagens pré-natais e aprendizagens durante os primeiros dias após o nascimento. Apontam-se evidências de que a exposição pré-natal a determinados estímulos possa alterar a sua efi cácia em um período pós-natal – mesmo com estí-mulos considerados aversivos incondicionados. Além disso, verifi ca-se a formação pré-natal de pareamentos respondentes aversivos. Com relação aos primeiros dias de vida pós-natal, apontam-se dados sobre a difi cul-dade de formação de pareamentos respondentes aversivos quando estes concorrem com a aprendizagem de relações de vinculação com o cuidador. De maneira ampla, sugere-se a importância de determinadas apren-dizagens pré e pós-natais na formação e fortalecimento do vínculo entre cuidador e fi lhote de forma que estas possam retardar o aparecimento de algumas associações com estímulos aversivas. Por fi m, conclui-se que considerar o nascimento como o começo de uma história de aprendizagem é um equívoco. Sendo a aprendizagem um fenômeno cumulativo, olhar para o período pré-natal pode somar na compreensão de comportamentos complexos que surjam e/ou que se mantenham a partir do contato com estímulos aversivos.
Analogias, metáforas e cognições – comentários a partirdo artigo de Ruiz e Luciano
Authors:   Universidade Federal do Pará, Tourinho Emmanuel Zagury
Published: January 2025

Discute-se brevemente quatro pontos identificados no artigo de Ruiz e Luciano sobre analogias, metáforas e cognições: (a) o avanço propiciado pela pesquisa sobre o responder relacional derivado à compreensão da cognição humana, (b) a relevância desse programa de pesquisas para o futuro da análise do comportamento humano complexo, (c) a centralidade de analogias e metáforas para uma compreensão comportamental da cognição e (d) a Teoria dos Quadros Relacionais (RFT – Relational Frame Theory) como modelo para a in-vestigação e interpretação da cognição na Análise do Comportamento. Argumenta-se que os dois primeiros pontos sintetizam importantes contribuições do artigo e independem das alegações que caracterizam os dois últimos, consideradas controversas e limitadoras da pesquisa comportamental da cognição.
O pensar como comportamento humano complexo – comentário ao artigo de Perez-Almonacid
Authors:   Universidade Federal do Pará, Tourinho Emmanuel Zagury
Published: January 2025

O texto discute a análise oferecida por Perez-Almonacid para o pensamento enquanto comportamento hu-mano complexo. Examinam-se algumas interpretações oferecidas para as proposições de Skinner e as im-plicações de uma proposta alternativa, de análise molar do comportamento. Destaca-se que um ponto chave a ser considerado diz respeito às (novas) unidades de análise admitidas como pertinentes a uma ciência do comportamento e aponta-se que a descrição de tais unidades ainda requer um esforço analítico. Tal descrição pode ser compatível com as contribuições de Skinner, distinguindo-se seu modelo explicativo (mais amplo) de seu programa de investigações empírico-experimentais (mais circunscrito a certas classes de fenômenos).
A concept highlighting the interplay between α-niche evolution and β-niche evolution in bacteria
Authors: Scheuerl Thomas , Barraclough Timothy , Rivett Damian
Published: January 2025

When bacteria evolve new traits, this can be either to our benefit or harm. Trying to steer and control evolution in desirable directions is a major, but daunting aspiration of recent research. In natural systems and complex communities, however, it is repeatedly observed that trait evolution regularly deviates from predicted avenues suggested by in vitro experimentation on monocultures. This pinpoints the effects of species interactions within microbial networks, which opens the door to use them to direct evolution. Unfortunately, this is not trivial; the impacts of ecological interactions between species within communities on evolutionary trajectories are not yet fully understood. Beside the introduced complexity caused by multiple species interactions, the nature of affected niches should also be important. When evolution of environmental β-niche traits (e.g. pH adaptation or antibiotic treatment resistance) is of concern, biotic interactions may have little direct impact. However, evolution of resource-based α-niche traits (e.g. broadened resource consumption) within competitive communities commonly is and could modify evolution of β-niches indirectly. Thus, co-evolving communities may display so far unpreceded opportunities to deflect trait evolution that cannot be achieved in other ways. Intelligent designed studies, building on ecological and evolutionary principles, will be needed to move this field forward.

Influence of Gravitation on the Origin and Propagation of Electromagnetic Radiation
Authors:   MSc in Engineering, Former Academic Member of Athens Institute for Education and Research, Bulgaria, Sharlanov Gocho V
Published: January 2025

Impressively, against the background of extraordinary advances in physics and technology, the mainstream continues to support
the two most obvious delusions in 20th-century physics: "special relativity" and "the accelerating expansion of the universe".
Both of these problems are based on a lack of understanding of the nature and behavior of electromagnetic radiation in the
gravitational field. In this paper, an attempt is made to present a new approach to this problem. To understand the real fabric
of the Universe, to understand the influence of gravitation on the characteristics of light (frequency, wavelength, speed of light
in vacuum), we must first be aware of the nature of electromagnetic radiation and the nature of the medium of propagation of
electromagnetic radiation. In this respect, as discussed at the 3rd Annual International Conference on Physics, 20 – 23 July 2015,
in Athens, Greece, the characteristics of electromagnetic radiation must be considered in two aspects:
• In the “local time-spatial domains in any place of the Universe” (the regions with a uniform intensity of the gravitational field),
and
• In the “global physical reality of the Universe” (related to the regions with different intensities of the gravitational field as an
infinite set of local time-space domains).
On the basis of the modern achievements of science and the analysis of the behavior of electromagnetic radiation in the local
and global physical reality of the Universe, this article contains the following scientific contribution: “Thesis On the Behavior
of Electromagnetic Radiation in the Gravitational Field of the Universe”, which should replace the erroneous “postulate of the
constancy of the speed of light for all inertial frames of reference”. This thesis also ends the delusion that the speed of light in
vacuum measured on the Earth’s surface is the limit speed for the entire Universe.
Cross-border Interrelationships in Rushdie, Ghosh, and Hosseini’s Novels: A Transnationalist Approach
Authors: Akhter Khadiza
Published: January 2025

This essay argues that the India-born expatriate writers Salman Rushdie and Amitav Ghosh, and the Afghan-American writer Khaled Hosseini have built fictional worlds consisting of people of diverse nations, races, colours, and religions in their respective novels Midnight’s Children (1981), The Glass Palace (2000), and The Kite Runner (2003), and many of these immigrant characters maintain sustainable connections with their countries of origin across borders. This study highlights the fact that British colonialism played a crucial role in large-scale movements of people, and many of the postcolonial countries are still struggling with myriad internal and external problems. As a result, countless people of these countries are eager to shift to economically advanced and politically stable countries. Yet, these same people are unable to disconnect from their original society and remain emotionally and psychologically moored to their roots. Drawing on the theoretical apparatus of transnationalism, this essay explores the reasons behind mobility outside one’s nation-state and the subsequent economic, political, and social impacts of transnational relationships ensuing from that. The study also examines how the characters adapt themselves to and whether they are permanently secured in a transnational space.

Feasibility of preparatory measures in the orthopedic treatment of TMJ dysfunction pain syndrome in patients with occlusion and articulation disorders.
Authors:   Bogomolets National Medical University, Kyiv, Ukraine, Proschenko A.
Published: January 2025

Summary. Violations of any link of the dental-jaw system, for example, irrational reproduction of occlusion on the chewing
surfaces during dental prosthetics, can disrupt its work, and as a result lead to symptomatic TMJ dysfunction, which may
manifest as a headache, pain in the TMJ area with radiation in temple, occiput, neck, problems with the innervation of the
facial area, and even disturbances in the work of the masticatory muscles.
Purpose: to assess influencing factors and the need for preparatory measures in the orthopedic treatment of functional
disorders of the masticatory apparatus caused by occlusal and articulatory disorders.
Research materials and methods. Clinical and laboratory examination and orthopedic treatment of 150 patients with
various variants of occlusal disorders were carried out, in 90 of them functional disorders of the masticatory apparatus were
not accompanied by pain syndrome, in 60 patients TMJ dysfunction with pain syndrome.
Research results. When assessing the state of the oral cavity, the following factors were identified that were associated with
the need for preparation for orthopedic treatment: stable functional displacement of the LV (p = 0.00002), decrease in the
interalveolar height (p = 1.60542E–08), unfixed bite (p = 4.06924E–11), the presence of maxillofacial deformities (p = 2.01E–11),
supracontacts (p = 0.0016), dental row defects (p = 0.0008), crown teeth defects (p = 0.003) , the presence of direct and indirect
restorations with irrationally modeled occlusion on the chewing surfaces of the teeth (p = 0.002), pathological types of bite
(p = 0.03).
Conclusions. When planning orthopedic treatment for patients with occlusal-articulation disorders and TMJ dysfunction,
71.33% needed special preparatory measures. The choice of the preparatory measures or their combination depended on the
clinical situation in the oral cavity and the choice of the occlusive therapy of TMJ dysfunction at the 1st stage of the orthopedic
treatment complex.
Keywords: orthopedic treatment, TMJ dysfunction, implantation, occlusion-articulation disorders.
Morphological characteristics of multiple cysts of the jaws in children
Authors:   Bogomolets National Medical University, Kyiv, Ukraine, Kiselyova N.
Published: January 2025

Purpose. This study aimed to analyze the morphological structure of multiple cysts of the jaws in children.
Methods. A retrospective analysis was conducted on 240 case histories of patients with cystic lesions of the jaws over 4 years. Nine
children were found to have multiple cystic lesions in their jaws. Fourteen orthopantomograms and six CT scans, and 42 histological
preparations, were analyzed.
Results. Four percent of patients with cystic neoplasms had multiple cystic lesions in their jaws. The average age of the patients was
12.22 ± 1.07 years. Polycystic jaws were accompanied to a greater extent by damage to the lower jaw in 64% (p = 0.017), in particular the
areas of the corner, second and third molars in 33%. Three types of cystic neoplasms were identified after reviewing 42 histological biopsies:
simple bone cyst (n = 5) in 33% of patients, dentigerous cyst (n = 15) in 88% of children, and odontogenic keratocyst (n = 22) in 100%.
Conclusions. Multiple cystic lesions of the jaws are associated with syndromes. Polycystic lesions of the jaws involve both the upper and
lower jaws and consist of cysts of both odontogenic and non-odontogenic origin. Odontogenic keratocysts are the most common cystic
lesions. These are characterized by: the presence of satellite cysts; a developed basement membrane, with pronounced keratinization
and parakeratosis; and more than 10 densely cellular layers of parakeratinized squamous epithelium.
Keywords: odontogenic keratocysts of the jaws, polycystic jaws, maxillofacial area, histological examination.
Prospects for the use of artificial intelligence in dentistry

Introduction. In recent years, artificial intelligence (AI) has found widespread use in healthcare and dentistry, where it has increased the
accuracy of diagnosis and clinical decision-making. However, artificial intelligence solutions have largely not entered everyday dental
practice, mainly due to limited data availability, accessibility, structure and complexity, lack of methodological rigor and standards in
their development, and practical questions regarding the value and utility of these solutions, but also ethics and liability. Any application of artificial intelligence in dentistry must demonstrate tangible value, such as improving access and quality of care, increasing efficiency
and safety of services, empowering patients and supporting medical research, or increasing sustainability.
Purpose: based on the analysis of literary sources, to determine the prospects and feasibility of implementing the use of artificial
intelligence in dentistry.
Materials and methods. Information search and analysis of scientific sources was carried out using scientometric databases Web of
Science, PubMed, Google Scholar over the last 10 years.
Conclusion. The next decade will show whether this time the expectations for real-world applications of artificial intelligence will be met,
or whether we will once again face an «AI winter» that will bury hopes and enthusiasm. There are valid concerns about the protection and
security of data and the transfer of important medical decisions to computers. At the same time, artificial intelligence has the potential
to revolutionize the health care industry, including dentistry, by helping to address the shortcomings of traditional dental care, which
have been heavily criticized.
Keywords: dentistry, artificial intelligence, deep learning, diagnostics and clinical decision-making.

The length of price&reimbursement negotiation procedures in Italy in the period 2021-2023 was independent from the price of medicines
Authors: Cocciolo Raffaella , Turella Paola , Pilunni Daniela , Navarra Pierluigi
Published: January 2025

Background: The duration of price&reimbursement (P&R) procedures is taken as a key performance indicator of Regulatory Agencies in Europe. In this study we have tested the hypothesis that the price of medicines may have negatively affected the duration of P&R negotiations in Italy in the period 2021-2023.
Methods: Data were retrieved from the Intexo database, which included all medicines with EC approval within the period 2021-2023. Biosimilars, generics, gene therapies, Sars-Cov-2 vaccines and medicines with no negotiated price at the datalock of December 2023 were excluded from the analysis. The ex-factory price of the most expensive package was taken as the price of each reimbursed medicine, whereas the time between the publication of EC decision in the European GU and the publication of P&R AIFA decision in the Italian GU (gazette-to-gazette time) as well as the time between the submission of P&R dossier and the publication of AIFA decision in the Italian GU (AIFA negotiation time) were taken as the procedure duration.
Results: Sixty-seven EC approved medicines completed the P&R procedure in Italy within the study period, and had a reimbursed price. The median and mean gazette-to-gazette times were 395 and 442.6 days, respectively, whereas the mean and median AIFA negotiation times were 389.5 and 434.7 days, respectively. The mean price was 10,942 euros. The analysis of correlation between the duration of procedure and the negotiated price showed that there is no correlation whatsoever between the length of procedures and the price of medicines.
Conclusions: We can reasonably exclude that the price of medicines negatively affected the duration of P&R negotiation procedures.

Ritual based idioms in Bosnian language

Summary
Speech situations always include elements of both verbal and non-verbal communication, and the essential meaning in it is only possible to reach in a holistic approach, because every speech situation implies a social, cultural and individual context containing collective experience, but all speech situations do not have to follow strictly established rules of verbal and non-verbal communication. However, in certain speech situations, due to functional repetitiveness, strictly established language rules with accompanying non-verbal elements of the speech situation naturally open up the possibility of the so-called phraseologising, which turns a free connection of words into a solid lexical connection. Such is the case with one group of idioms that originate from rituals practiced in different epochs of the historical development of society. Namely, we call such idioms ritual based idioms because they probably represent the most advanced part of a certain ritual that has been verbalized in the modern language and in most cases has lost its connection with the denotative meaning of its components. The connection with the denotative meaning can be reconstructed through diachronic studies which, as expected, show that the background motivational mechanisms in these idioms are mainly found in the potential of their denotative meanings.

KEY WORDS: rituals, culture, phraseologisation, strong lexical connection, ritual based idioms

Transmission by laser is a cost-effective way to send signals to space vehicles. Signals are encoded so that zeroes and ones are recognized by different intensity levels at the receiver. The process should be optimized so that the gap in intensity between zeroes and ones is large enough that correct decoding will occur even in the presence of noise. Global and local optimization schemes are presented using numerical and analytical techniques. The results obtained produce wider gaps than those currently available.

Tujuan penelitian ini adalah menganalisis perlakuan akuntansi aset tetap dalam kerangka entitas komersial dengan menggunakan SAK Entitas Privat. Sumber data yang digunakan adalah data primer berupa hasil wawancara dan observasi, sedangkan data sekunder berupa data olahan suatu penelitian. Metode pengumpulan data yang digunakan adalah wawancara, observasi, dan dokumentasi. Perlakuan akuntansi aset tetap dimulai dari pengakuan aset tetap, pengukuran awal, pengukuran setelah pengakuan awal, penyusutan aset tetap, penurunan nilai, penghentian pengakuan, pengungkapan, dan penyajian aset tetap. Hasil penelitian ini menunjukkan bahwa perusahaan belum menerapkan perlakuan akuntansi yang diamanatkan oleh SAK EP yang dijadwalkan berlaku pada tahun 2025. Tinjauan atas daftar aset perusahaan menunjukkan bahwa masih terdapat aset tetap yang tidak lagi memberikan manfaat ekonomis. Apabila aset tetap masih memberikan manfaat, sedangkan umur ekonomisnya telah habis, maka perlu dilakukan penilaian kembali atau diberikan penjelasan khusus dalam laporan keuangan mengenai pengungkapan dan penyajian aset tersebut. Dengan demikian, hasil penelitian ini menunjukkan bahwa memberikan arahan bagi perusahaan dalam memilih perlakuan akuntansi yang paling tepat dengan fokus pada perlakuan akuntansi aset tetap sebagai bagian dari penerapan awal SAK EP dalam menyajikan nilai aset tetap yang akurat untuk tujuan penyusunan laporan keuangan yang lebih relevan dengan kondisi RDV.
Historical perspectives supporting the ambitious anesthetist aiming for zero nausea/vomiting: should one trust every consensus statement every time?

Within the domain of perioperative prophylaxis against postoperative nausea and/or vomiting (PONV), there seems to be (i) a consensus-guided “hard stop” recommendation after four prophylactic anti-emetic medications are utilized, and (ii) an assumption that each of the four “usual” PONV medications/categories produces 25% risk reduction from the “previous baseline”, representing a “law of diminishing returns.” Meanwhile, recently-described 5-medication PONV prophylaxis (palonosetron, perphenazine, aprepitant, dexamethasone, diphenhydramine) has been observed to achieve 90%–95% prophylaxis success, particularly in patients receiving intrathecal morphine (a known, potent emetogenic stimulus). This meaningful prevention thematically differs from the scholarly prevention benchmark that may be over-reliant on patient-specific preoperative risk factors, described in the 1990s and before, dictating prophylaxis strategies. Meaningful prevention with 5-medication PONV prophylaxis (which we recommend before entry into the operating theater) (i) may serve as a surprisingly effective antecedent to further avoid postoperative opioids, (ii) may be augmented throughout hospitalization and convalescence with daily “booster dosing”, and (iii) may (in combination with booster dosing) mitigate possible “rebound nausea” that has been reported by esteemed PONV thought leaders in the context of post-discharge nausea and/or vomiting. The described processes (pan-prophylaxis before emetic stimuli are incurred, antiemetic booster dosing, and potential downstream opioid reduction by enhancing adherence to postoperative oral/enteral non-opioid analgesic formulations) would seem to create a win-win scenario for patients and hospitals alike. The described antiemetic techniques remain compatible with available opioid-free anesthetic techniques [lidocaine, acetaminophen, N-methyl-D-aspartate (NMDA) antagonists, etc.]. Some perspectives shared herein may further inform as to how and why.

Introduction

Accurate prediction of knee biomechanics during total knee replacement (TKR) surgery is crucial for optimal outcomes. This study investigates the application of machine learning (ML) techniques for real-time prediction of knee joint mechanics.

Methods

A validated finite element (FE) model of the lower limb was used to generate a dataset of knee joint kinematics, kinetics, and contact mechanics. The models were trained on joint alignment data, ligament information, and external boundary conditions. Several predictive algorithms were explored, including linear regression (LRM), multilayer perceptron (MLP), bi-directional long short-term memory (biLSTM), convolutional neural network (CNN), and transformer-based approaches. The performance of these models was evaluated using average normalized root mean squared error (nRMSE).

Results

The biLSTM model achieved the highest accuracy, with a significantly lower nRMSE compared to other models. Compared to traditional FE or rigid body dynamics models, these predictive models offered significantly faster prediction speeds, enabling near-instantaneous insights into the TKR system’s performance. The small size of the predictive models makes them suitable for deployment on edge devices potentially used in operating rooms.

Discussion

These findings suggest that real-time biomechanical prediction using biLSTM models has the potential to provide valuable feedback for surgeons during TKR surgery. Applications of this work could be applied to provide pre-operative guidance on optimal target implant alignment or given the real-time prediction ability of these models, could also be used intra-operatively after integration of patient-specific intra-op kinematic and soft-tissue information.
