O uso de cirurgia robótica em doenças cardíacas valvulares tem ganhado destaque como uma abordagem minimamente invasiva, oferecendo benefícios significativos em comparação aos métodos convencionais. Estudos modernos exploram os avanços tecnológicos que permitem maior precisão, menor trauma tecidual e recuperação mais rápida. Os sistemas robóticos, como o Da Vinci, proporcionam aos cirurgiões maior destreza, visão tridimensional ampliada e maior controle durante os procedimentos, fatores que são cruciais para o sucesso em reparos e substituições valvulares.
Pesquisas mostram que a cirurgia robótica está associada a menores taxas de complicações, menor tempo de internação hospitalar e retorno mais rápido às atividades diárias. Esses procedimentos minimamente invasivos também estão relacionados a menor dor pós-operatória e menor risco de infecções, sendo particularmente vantajosos para pacientes idosos ou com comorbidades.
Além disso, revisões sistemáticas destacam que a cirurgia robótica em doenças valvulares cardíacas apresenta resultados clínicos comparáveis ou superiores aos métodos tradicionais, com redução de mortalidade e melhora da qualidade de vida dos pacientes. No entanto, a implementação dessa tecnologia requer treinamento especializado e infraestrutura adequada, sendo essencial avaliar cuidadosamente sua aplicabilidade em cada caso.
Portanto, a adoção de abordagens robóticas em doenças cardíacas valvulares representa um avanço promissor, reforçando a importância de uma prática médica orientada por evidências e centrada no paciente.

Authors: Mirayani Luh Putri Mas , Rengganis RR. Maria Yulia Dwi , Dewi I Gusti Ayu Ratih Permata
Published: December 2024

This study examines the influence of Dividend Payout Ratio (DPR), Earning Per Share (EPS), and Debt to Equity Ratio (DER) on Stock Returns in companies listed on the LQ45 Index of the Indonesia Stock Exchange (IDX) during the 2021–2023 period. Using a quantitative approach, this research analyzed data from annual financial reports of 22 companies selected through purposive sampling, with a total of 66 observations. Multiple linear regression analysis was employed to evaluate the relationships between variables. The results indicate that DPR and EPS have a positive and significant impact on Stock Returns, with respective p-values of 0.001. This suggests that higher dividends and improved financial performance significantly enhance stock returns. On the other hand, DER does not have a significant influence on Stock Returns. This study provides practical implications for companies to strengthen their dividend policies and financial performance to attract investors. Investors are recommended to use DPR and EPS as primary indicators in forming an optimal investment portfolio. The findings contribute to the theoretical literature on financial ratios and stock performance in developing markets and suggest opportunities for future research, including additional variables such as macroeconomic factors or market conditions, to enhance Stock Return prediction models.

The article provides a theoretical analysis related to the problem of forming a culture among university students. It is noted that in modern scientific discourse there is still no unambiguous approach to defining the definition of “legal literacy”. An analysis of practical work is presented, aimed at identifying the level of legal literacy of students-future teachers, their self-esteem in legal knowledge, and factors influencing its formation. Conclusions are drawn that legal literacy determines the nature of a person’s behavior based on her civic position, is the basis for the formation of a person’s legal culture, and also represents a complex, multifaceted process of mastering technical knowledge that is necessary for the implementation of professional activities and maintaining a civic position, laid down in regulatory legal acts, moreover, mastering the legal competencies necessary for teaching activities.
A middle-aged male with incidentally-discovered primary familial brain calcification: A case report
Authors: Farkas Hal Steven , Leschek Richard Thomas , Leschek Ellen Werber
Published: December 2024

Primary familial brain calcification (PFBC) is a neurodegenerative disorder characterized by bilateral basal ganglia and dentate nuclei calcifications, with signs and symptoms often manifesting between 30 and 60 years, although many affected individuals remain asymptomatic. Herein, we present a 51-year-old male with bilateral basal ganglia and dentate nuclei calcifications found incidentally by brain computed tomography (CT) performed for sinus complaints. He had no associated signs or symptoms. The proband’s deceased mother’s last brain CT showed comparable brain calcifications. The proband’s daughter was being evaluated for neurologic signs and symptoms associated with abnormal lesions on brain magnetic resonance imaging. Her brain CT revealed bilateral basal ganglia calcifications. Genetic testing on the proband and his daughter revealed a novel heterozygous autosomal dominant mutation in the platelet-derived growth factor subunit B gene. Since most affected individuals are often past childbearing years before PFBC diagnosis, it is crucial to perform family planning and genetic counseling in consideration of family history.

Palm Oil Smallholders in Peril: Indonesia Urgency in Aiding Smallholders to Compete Fairly in their Playing Field
Authors: Yenny Oktavani , Simbolon Putu George Matthew
Published: December 2024

This research is conducted to express the urgency for the Government of Indonesia to adopt a regulation concerning the protection of palm oil smallholders. Such adoption is necessary since the partnership agreement between this minor group with the non-plantation enterprise is ineffective due to the conflicting interests between the Minister of Agriculture and the Minister of Industry. To achieve this purpose, this article is written based on doctrinal research by gathering rules under the MSMEs Law, the Competition Law, the Capital Investment Law, the Job Creation Law, and the SCM Agreement. This article is also supported by the justice fairness theory by Rawls. The first discussion of this article discusses the urgency to adopt this government regulation based on the MSMEs Law and the Competition Law which is to enforce the partnership agreement. Furthermore, the second discussion analyzes the Capital Investment Law and the Job Creation Law so that this aspired law shall balance the rights and obligations of the smallholders and the non-plantation enterprise. Last but not least, the third discussion discusses what to anticipate according to the WTO rules on subsidies. In the aftermath, this article suggested next research discussing the distribution of authorities between the MOA and the MOI.

Dažas mūsdienu latgaliešu runas korpusam paredzēto ierakstu transkribēšanas problēmas
Authors:   Rēzeknes Tehnoloģiju akadēmija, Gusāns Ingars
Published: December 2024

A group of researchers from Rēzekne Academy of Technologies is actively involved in the project “Diversity of the Latvian Language in Time and Space”, which involves data acquisition, processing and adding ~10 hours of audio recordings to the corpus of modern Latgalian speech (MuLaR) and their transcription.
The creators of the MuLaR have agreed to transcribe the spoken texts into orthographic Latgalian language. The ELAN software was used to transcribe the interviews from audio and video recordings.
The MuLaR creators have developed their own conventions for transcribing text to create transcripts that are understandable to a wide range of stakeholders. At the same time, they try to capture the features of the spoken text as accurately as possible.
The aim of this study is to analyse the challenges encountered in transcribing audio recordings and to propose potential solutions.
By March 2024, the author had transcribed 16 interviews totalling 3.5 hours. This includes 14 interviews from the field study in Aglona conducted in 2021 and two radio interviews from the “Latgolys stuņde” programme spanning 2022–2023.
In the process of transcription, the author has encountered three problematic cases that need attention when creating a corpus platform: 1) the use of phonetic variants and parallel forms in one noun case (some words have more than four phonetic variants); 2) the use of homoforms; 3) the use of abbreviated forms.
During the study, the working group agreed that the elongated -y- would be represented as -yy-, following the previously established convention. The issue of establishing a well-organized speech corpus platform is under consideration, featuring either a searchable alphabetical index of word forms or even a separate thesaurus showing parallel forms, abbreviations or phonetic variants of words encountered in the transcription process. A challenging situation arises when one form corresponds to multiple conjugations. In such cases, the researcher must manually analyse the material to determine the appropriate conjugation for each form. These cases are likely to expedite the development of a morphologically labelled corpus.
Radikaali porvarillinen vasemmisto – Nuorsuomalaisen Puolueen vasemmistoliberaali jakobiiniklubi ja sen vaikutus
Authors: Kolumäki Juha
Published: December 2024

1900-luvun alussa porvarillisen poliittisen kentän laitimmaista vasemmistoa edustivat usein voimakkaita yhteiskunnallisia uudistuksia ajaneet radikaalit sosiaaliliberaalit. Myös Suomessa, Nuorsuomalaiseen Puolueeseen kehittyi sen viimeisinä vuosina tällainen ryhmittymä. Jakobiiniklubiksi itsensä nimennyt ryhmä pyrki tekemään vähintään yhtä selvän rajan oikealle konservatiivisiin porvareihin kuin vasemmalle sosialisteihin. Kuvaavaa ryhmän radikaalisuudelle on, että se mielsi tavallaan konservatiiveiksi jopa nuorsuomalaisten perinteisen vasemmistosiiven ”varpuset”. Ryhmän keskeisimpiin jäseniin kuuluivat Rudolf Holsti, Heikki Ritavuori ja K. N. Rauhala. Ryhmän varsinainen toiminta kesti vain syksyn 1917 ajan, mutta sen yhteen keräämät henkilöt jatkoivat radikaalia toimintaa vuoden 1918 myllerryksissä, jolloin he ajautuivat ensin tasavaltalaisen propagandan johtoon ja edelleen Kansalliseen Edistyspuolueen ytimeen.
In the early 20th Century, the most left-wing representatives of the bourgeois political field were the radical social liberals, who often advocated for strong societal reforms. In Finland, also, such a group was formed within the Young Finns party during the party’s last years. The group named themselves the Jacobin Club, and they tried to strongly differentiate themselves both from the conservative bourgeois in the right and from the socialist in the left. Emblematic of the radicalism of the group is that they regarded even the Sparrows – the traditionally leftist wing of the Young Finns – as kind of a conservative group. The central figures of Jacobines were Rudolf Holsti, Heikki Ritavuori and K. N. Rauhala. In reality, the group was active only for the Fall of 1917, but the people it gathered together continued their radical policies during the 1918 upheaval. They first drifted into leading the propaganda for republicanism and from there to the heart of the National Progressive Party.
Suomen ja Venäjän kulttuuriyhteistyö 2000-luvulla, esimerkkinä Suomalais-venäläinen kulttuurifoorumi 2000-2022
Authors: Savonen Riku
Published: December 2024

Venäjän hyökkäys Ukrainaan helmikuussa 2022 on lisännyt tarkastelua Suomen ja Venäjän väliseen yhteistyöhön 2000-luvulla. Suurin osa yhteistyöstä on päättynyt, keskeytynyt tai hiipunut nopeasti vuoden 2022 jälkeen. Kulttuuri oli aiemmin aktiivinen toimiala, jossa laajaa suomalais-venäläistä vuorovaikutusta on ollut ruohonjuuritasolta valtiontasolle asti. Katsauksessa esitellään tapausesimerkkinä Suomalais-venäläinen kulttuurifoorumi, joka kannusti kulttuurihankkeiden syntymiseen suomalaisten ja venäläisten toimijoiden välillä. Sen kautta avataan näkymiä jatkotutkimukselle, millaisia motiiveja kulttuuriyhteistyön tekemisen taustalla oli Suomessa ja Venäjällä oli. Voidaanko kulttuuriyhteistyön taustalla löytää agendoja, jotka voidaan tulkita pyrkimykseksi vaikuttaa toisen maan toimijoihin.
Role Of EMG Biofeedback On Ankle To Improve Balance In Young Old Geriatric Population - A Randomised Control Trial
Authors: Aishwarya Valiv  , Sabah Thaver  , Ali Irani
Published: December 2024

BACKGROUND -
Falls in the elderly have become an significant public health issue. Approximately 30% of the older population falls once a year, with greater risk for older women. WHO addresses the situation as a public health issue because falls lead to injuries and fractures.4 It is known that during quiet standing, sway of entire body is correlated highly with the ankle joint rotation and this explains why muscles crossing the ankle joint are able to provide sensory information necessary to maintain upright standing. The ankle strategy is particularly effective in responding to the small and slow perturbations, and these muscles play a crucial role in the fine-tuned adjustments needed for postural control during activities such as standing, walking, or other weight-bearing tasks. Electromyographic (EMG) biofeedback serves as precious physiotherapy tool in enhancing and optimizing the ankle strategy, particularly in the environment of balance and postural control. With the use of EMG-biofeedback, elderly individuals can be taught to manipulate previously uncontrollable or unfelt events by modifying the signals that are shown.
METHOD – Total 84 subjects participated in the study. Subjects were screened according to the inclusion and exclusion criteria. Baseline outcome measures which included the MiniBEST test and functional reach test were assessed. MiniBEST test is used for dynamic balance and functional mobility, it contains 14 items whereas functional reach test was used to assess static balance with outstretched hand. Subjects were randomly allotted into three groups. Group 1 was given balance protocol. Group 2 was given EMG Biofeedback with balance exercises. The group 3 was given only EMG Biofeedback, outcome measures were reassessed post intervention. This study showed that statistical and clinical significance was observed in all the intra-groups(p<0.05). Within the group the study showed greater improvement clinically and statistically in Group 2. ANNOVA test showed Group 3 being more affective compared to other 2 groups.
CONCLUSION - The study concluded that EMG Biofeeback training should be included in along with exercise protocol to improve balance.

Published: December 2024

Eye tracking technology has become increasingly prevalent in scientific research, offering unique insights into oculomotor and cognitive processes. The present article explores the relationship between scientific theory, the research question, and the use of eye-tracking technology. It aims to guide readers in determining if eye tracking is suitable for their studies and how to formulate relevant research questions. Examples from research on oculomotor control, reading, scene perception, task execution, visual expertise, and instructional design are used to illustrate the connection between theory and eye-tracking data. These examples may serve as inspiration to researchers new to eye tracking. In summarizing the examples, three important considerations emerge: (1) whether the study focuses on describing eye movements or uses them as a proxy for e.g., perceptual, or cognitive processes, (2) the logical chain from theory to predictions, and (3) whether the study is of an observational or idea-testing nature. We provide a generic scheme and a set of specific questions that may help researchers formulate and explicate their research question using eye tracking.

Authors: Ülken Funda , Karagöz Ertuğrul
Published: December 2024

Die Corona-Pandemie hat in den letzten Jahren die globale Gesellschaft nachhaltig beeinflusst und stellte eine große gesellschaftliche Herausforderung dar, was zur Wahl von „Corona“ als Wort des Jahres 2020 durch die Gesellschaft für deutsche Sprache (GfdS) führte. Die verstärkte Nutzung sozialer Netzwerke wie Twitter, Instagram, Facebook und YouTube beeinflusste die Art und Verbreitung von Pandemie-bezogenen Beiträgen erheblich und förderte gleichzeitig die rasche Verbreitung von Verschwörungstheorien und Falschinformationen zur Corona-Pandemie und Impfung. Twitter etablierte sich als Hauptkommunikationsmittel während der Pandemie und wurde von Politikern, Institutionen, Bundesbehörden und Virologen intensiv genutzt, um massenmedial verwertbare Informationen schnell zu verbreiten. Diese Studie untersucht aus pragmalinguistischer Perspektive die Nutzung von Twitter als Kommunikationsmittel während der Pandemie, insbesondere durch impfbezogene Textbeiträge staatlicher Behörden, Institutionen, offizieller Einrichtungen sowie Virologen. Eine detaillierte Sprechaktanalyse ausgewählter Tweet-Beispiele wird durchgeführt, um die Handlungswerte der Sätze (Illokutionen) zu analysieren. Ziel ist es, die illokutionären Zwecke der Tweets zu identifizieren und die entsprechenden Handlungstypen gemäß der Searle’schen Klassifikation darzustellen. Es wurden jeweils 15 Tweets von staatlichen Behörden, Institutionen, offiziellen Einrichtungen und Virologen aus dem Zeitraum von 2020 bis 2023 ausgewählt. Die Untersuchung fokussiert sich auf die in den Tweets ausgeführten Sprechakte und deren Verbindung zu den Textfunktionen. Die Auswahl der Tweet-Beispiele basierte auf Hashtags, die relevante Begriffe wie „Coronaimpfausweis“, „Coronalage“, „Coronawelle“, „Coronagipfel“ und „Coronahilfe“ umfassen.

Published: December 2024

No Brasil, mesmo diante de diversas iniciativas e projetos voltados para a mitigação das perdas hídricas e a promoção da eficiência energética, os prestadores de serviços públicos responsáveis pelo abastecimento de água e pelo esgotamento sanitário ainda registram índices elevados em comparação aos padrões internacionais observados em nações desenvolvidas. A otimização da eficiência de um sistema de fornecimento hídrico tem como escopo primordial atender às demandas de consumo, reduzindo os custos operacionais e energéticos por meio da operação eficiente das bombas. A redução dos gastos em um sistema de abastecimento de água representa um dos desafios preponderantes enfrentados pelas empresas de saneamento, sendo o consumo energético uma das principais fontes de despesas. Neste contexto, o presente estudo propõe a diminuição das exigências energéticas do sistema de abastecimento de água da cidade de Nobres-MT, que conta com aproximadamente 15.000 habitantes. Para tal, aplicou-se um aprimoramento não linear por meio de algoritmos genéticos, buscando alcançar o menor dispêndio possível dessas bombas, sempre respeitando as restrições do sistema. Através de modelagem matemática e hidráulica, simulações de cenários (demanda máxima e mínima) e do modelo de otimização desenvolvido, foram obtidas reduções de custo na ordem de 29% a 40%. Com a realização deste estudo, sugere-se a realização de pesquisas que busquem revisar o enquadramento tarifário, uma vez que, quando adequadamente gerido, um sistema baseado em tarifação horo-sazonal se revela significativamente mais econômico que o convencional. Ademais, é crucial o aprimoramento contínuo do trabalho, obtendo-se mais dados do sistema em questão para que os resultados se aproximem ainda mais da realidade.

Authors: Rosa David Maycon Schimitt , Barbosa Jonathan Lima , Silva Welitom Ttatom Pereira da , Santos Aldecy de Almeida
Published: December 2024

Uma questão de grande relevância na operação das unidades do sistema de abastecimento de água é o monitoramento preventivo das variáveis que influenciam o funcionamento de cada unidade. Entre essas variáveis, que são fundamentais para a adequada operação das unidades de reservação e distribuição, destacam-se a pressão hidrostática e hidrodinâmica. A ausência de acompanhamento rigoroso dessa variável nas unidades do sistema pode acarretar danos aos componentes do sistema de abastecimento de água (SAA), dificultando sua operação e tornando a manutenção um processo oneroso. Diante disso, o presente estudo teve como objetivo mitigar as dificuldades relacionadas ao monitoramento da pressão hidrostática e hidrodinâmica no município de Nobres/MT. Foi realizada uma revisão da literatura para diagnosticar a operação das unidades de distribuição e reservação do SAA, além da elaboração de um aparato experimental, utilizando Arduino, que foi instalado em campo após sua calibração. O dispositivo montado demonstrou uma resposta satisfatória para o armazenamento dos dados, embora os erros associados às leituras não tenham alcançado as expectativas desejadas. Ademais, o recipiente projetado para o dispositivo apresentou avarias durante os cinco meses de exposição em campo. Desse modo, foi desenvolvido um dispositivo alternativo para a medição de pressão hidrostática e hidrodinâmica, destinado ao SAA de Nobres/MT, com um funcionamento análogo aos Dataloggers disponíveis no mercado.

Published: December 2024

O monitoramento da qualidade das águas superficiais reveste-se de suma importância para uma gestão eficaz dos recursos hídricos, uma vez que a carência de dados quali-quantitativos detalhados impõe um desafio considerável à preservação dos corpos d'água. Neste cenário, o objetivo central deste estudo consistiu em investigar os aspectos qualitativos da água do Ribeirão Caiana, bem como o uso e a ocupação do solo em sua sub-bacia, almejando compreender os fatores que influenciam a qualidade desse manancial. A metodologia adotada envolveu a realização mensal de análises físico-químicas (temperatura da água, condutividade elétrica, sólidos totais, turbidez, pH, demanda bioquímica de oxigênio, oxigênio dissolvido, fósforo total e nitrato) das amostras de água do Ribeirão Caiana, abrangendo tanto o período de seca quanto o de chuva. Os resultados das análises foram confrontados com os parâmetros estabelecidos na Resolução CONAMA nº 357/2005. Para a análise do uso e da ocupação do solo, recorreu-se ao software ArcGis e a dados do MapBiomas, visando identificar as classes de uso e ocupação do solo e suas respectivas áreas no intervalo de 1992 a 2022. Segundo os resultados obtidos, os parâmetros físicos e químicos mantiveram-se dentro dos limites estipulados pela Resolução CONAMA nº 357/2005, excetuando-se o pH, em razão das características naturais da bacia, como o solo e a vegetação, e o oxigênio dissolvido, que apresentou uma variação pontual em maio de 2023, em decorrência da diminuição da vazão. Observou-se um aumento expressivo nas áreas destinadas à agropecuária, com destaque para pastagens e cultivo de soja, resultando na diminuição das áreas de vegetação nativa. À luz dessas conclusões, torna-se imprescindível a adoção de medidas que visem à preservação da qualidade da água e à saúde dos ecossistemas na sub-bacia do Ribeirão Caiana.

Authors: Rondon Andreia Catarina , Barbosa Jonathan Lima , Santos Aldecy de Almeida
Published: December 2024

Em regiões rurais, a gestão do esgoto tem se tornado uma preocupação cada vez mais premente, dada a ameaça que representa à saúde pública e ao meio ambiente. Este aspecto se torna especialmente alarmante em áreas úmidas, como o Pantanal. A complexidade dessa situação é acentuada pelo fato de se tratar de uma planície alagável, o que torna a implementação de sistemas convencionais de tratamento de efluentes uma tarefa desafiadora. Nesse sentido, o presente estudo visa avaliar uma alternativa sustentável para o tratamento de esgoto sanitário em ambientes úmidos. A metodologia adotada compreendeu as seguintes etapas: i) revisão da literatura; ii) caracterização dos parâmetros físicos, químicos e microbiológicos do efluente bruto; iii) desenvolvimento do projeto, instalação e monitoramento do Tanque de Evapotranspiração (TEvap); e iv) avaliação do custo de implementação do sistema. Segundo Galbiati (2009), com os dados obtidos das características físicas e químicas, o esgoto proveniente da residência foi classificado como de média carga, apresentando resultados de DBO de 211,25 mg/L e DQO de 479,25, evidenciando a necessidade de tratamento. Ademais, o TEvap revelou-se uma alternativa sustentável e economicamente viável. Ao comparar o custo estimado do TEvap, utilizando um tanque de IBC para uma unidade familiar de uma pessoa, com o custo de sistemas tradicionais de coleta de esgoto em alvenaria, conforme demonstrado nos orçamentos das tabelas 5 e 6, constatou-se que o investimento proposto é suficiente para a construção de cinco unidades familiares de uma pessoa, utilizando o tanque de IBC. Essa solução não apenas se mostrou eficaz no tratamento de esgotos, mas também promete melhorar significativamente a qualidade de vida da população, contribuindo assim para a preservação do meio ambiente.

Energy Performance Contracting (EPC) represents a promising approach to improving Energy Efficiency (EE) as well as reducing greenhouse gas emissions in various sectors. In the realm of EPC projects, accurate Measurement and Verification (M&V) with regard to energy savings is vital for these initiatives to be successful. Nevertheless, the risks related to M&V in EPC projects were not thoroughly studied. Moreover, the effectiveness with regard to EPC projects depends crucially on the accurate M&V of energy savings, which is often fraught with risks and uncertainties. This paper applied the pre-recording systematic reviews and meta-analysis (PRISMA) approach to finding the primary data based on a few keywords such as “risk or uncertainty, measurement and verification”. Based on advanced searching on SCOPUS and Web of Science (WOS), we found (n=32). Expert scholars decided to develop three themes, which are (1) challenges and issues in M&V, (2) methods of M&V, and (3) risk mitigation strategies in M&V. In summary, this systematic review provides a comprehensive overview of the critical challenges and issues surrounding M&V risks in EPC projects and offers a roadmap for enhancing the reliability and credibility of M&V. By addressing these challenges and implementing the recommended strategies, stakeholders can navigate the complexities of EPC projects more effectively, ultimately advancing the adoption of sustainable energy practices and achieving meaningful environmental and financial benefits.

This paper proposes an autonomous robotics system based on a single LIDAR sensor for delivering goods. There are needs to deliver goods such as medical supplies to the hospital and document in office.  Although this task is simple, the delivery task is time consuming, tedious, and boring. In this regard, autonomous robotic systems could be a suitable solution. Here-in, we proposed the use of a single RP-LIDAR sensor in a robotic system that is sufficient for delivering goods in indoor environment. The robotic system uses autonomous navigation module which consists of simultaneous localization and mapping (SLAM) of the environment, and path planning for the robot to move safely from its current location to a desired position. In the context of SLAM, Hector SLAM method was opted due to its capability to harness sufficient data from a single LIDAR sensor. When it comes to path planning, the system employs a two-pronged approach. First, a global planner, utilizing the A* algorithm, facilitates long-distance trajectory planning while accounting for static obstacles. Second, a local planner, employing the Trajectory Rollout and Dynamic Window Approach (DWA), ensures real-time obstacle avoidance in the presence of moving obstacles. The approach was evaluated in a laboratory environment (11 meter by 8 meter) and successfully built a path that avoided obstacles in both static and dynamic conditions. This approach for autonomous robotics using a single RP-LIDAR sensor has the potential to revolutionize the delivery industry and other sectors that require autonomous navigation.

Digital technologies have transformed many industries’ landscapes, presenting unprecedented opportunities and formidable challenges. Adopting digital technologies is unavoidable but, thus far, the service industry seems quite slow in responding to the changes. Hence, this systematic literature review (SLR) was conducted to determine the pivotal roles towards successful adoption of digital business platforms and the impacts of such adoptions. Utilizing a systematic review methodology, this research meticulously surveys and synthesizes the extant body of knowledge, with a particular focus on illuminating the determinants of adoption and unraveling the multifaceted challenges faced by service organizations. This systematic analysis draws from 21 scholarly publications meticulously sourced from reputable databases such as SCOPUS, Web of Science (WOS), and ECONBIZ, spanning the years 2021 to 2023. These publications are categorized into three principal themes: factors that influence the adoption of digital platforms (comprising 11 articles), the impact of adopting digital platforms (encompassing 6 articles), and the operational and strategic use of digital platforms (encompassing 4 articles). The SLR has uncovered a gap in the existing literature and provides fundamental insights to the practitioners.

O Fibroadenoma Gigante Juvenil (FGJ) é uma condição clínica rara e benigna que afeta pacientes jovens, entre 10 e 18 anos. Histologicamente, caracteriza-se como uma lesão circunscrita, com proliferação rápida do estroma e epitélio mamário, que pode estar associada a mutações genéticas. Para o diagnóstico, é necessária uma avaliação clínica e histológica da lesão, a fim de descartar outras afecções mamárias, como o tumor filoide. Neste caso, trata-se de uma paciente de 12 anos com uma lesão de grande volume na mama direita, surgida seis meses antes da consulta. A avaliação ultrassonográfica evidenciou uma massa sólida, hipoecoica e com bordas bem definidas, que, juntamente com a biópsia, confirmou o diagnóstico de FGJ. Diante das características da lesão e de seus impactos na vida da paciente, optou-se pela abordagem cirúrgica, priorizando a preservação de tecido mamário saudável. A massa retirada foi analisada anatomicamente e confirmou o diagnóstico de FGJ, descartando outras patologias. O manejo dessa condição requer uma abordagem personalizada, que leve em consideração as características da lesão e da paciente, de modo a equilibrar as questões estéticas e a saúde mamária. No caso relatado, a conduta cirúrgica resultou em um desfecho satisfatório, atendendo às necessidades médicas, estéticas e psicossociais da paciente. Este trabalho, portanto, destaca a importância do diagnóstico precoce e da conduta multidisciplinar necessária para o tratamento de pacientes com FGJ.
