Authors: Yang Lei , Cao Jianwen , Xu Guangpei
Published: February 2025

ABSTRACT To explore the impact of age on the fattening effects in Zhedong white geese, this experiment selected 240 geese to undergo a three-week fattening period starting at 49 d and 70 d. The results showed that the final weight and feed-to-gain ratios (F/G) in the first and second weeks were significantly higher in the geese that started fattening at 70d compared to those starting at 49d (P<0.05). The F/G ratio in the third week was significantly lower in the 70d group compared to the 49d group (P<0.05). Additionally, the weights of the breast muscle, leg muscle, abdominal fat, intestinal fat, gizzard pH, and heart were significantly higher in the 70d group (P<0.05). The meat color L values and b* values of the breast and leg muscles were higher in the 70d group, while the leg muscle pH was significantly higher in the 49d group (P<0.05). Overall, the analysis suggests that starting fattening at 70d can improve the final weight and slaughter performance of Zhedong white geese but also increases the F/G ratio and reduces carcass quality and meat color. Therefore, the fattening effects are superior when started at 49d.

ABSTRACT The khapra beetle (Trogoderma granarium) is a notorious pest causing significant damage to stored grains, leading to substantial economic losses globally. This study investigates the insecticidal efficacy of methanolic extracts derived from two indigenous plants, Cannabis sativa and Cymbopogon citratus, alongside two entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae, against T. granarium. The study assesses mortality rates, weight loss in infected wheat seeds, and adult beetle emergence. Results revealed that higher concentrations and extended exposure periods of all extracts significantly increased mortality rates while simultaneously reducing seed weight loss and adult emergence. C. sativa at 25mg/mL achieved the highest mortality rate of 78.92% ± 5% after 72 hours, with C. citratus showing a 60.52% ± 2.43% mortality rate under similar conditions. The fungi extracts, particularly at concentrations of 108 spores/mL, demonstrated substantial efficacy, with B. bassiana and M. anisopliae reducing adult emergence rates to 42.11% ± 1.92% and 41.17% ± 1.92%, respectively. These findings highlight the potential of these methanolic extracts as effective biopesticides for managing T. granarium infestations in stored grains, offering a natural alternative to chemical pesticides.

Abstract This study analyzed the properties of three-dimensional (3D)-printed resins designed for interim restorations and subjected to different printing and post-curing protocols. Specimens were manufactured with two 3D-printed resins for interim restorations at varying exposure times per layer, in accordance with the manufacturer’s recommendations (Tm) or using a calibrator (Tc). Subsequently, the specimens were post-cured for 5, 10, or 15 min. Trueness, surface roughness, and color analyses were performed. For biological characterization, the specimens were incubated for up to 72 h in a culture medium, and the extracts were applied at 24-h intervals to keratinocyte cells (NOK-Si). Cellular metabolism was evaluated after 1 and 3 days. Leaching of residual monomers from the extracts was evaluated. Data were analyzed using two-way analysis of variance (ANOVA) and Tukey’s honestly significant difference (HSD) test (α = 5%). The exposure time beyond Tc resulted in specimens with increased trueness and smoother surfaces. Color stability was also influenced by the type of resin and post-curing time; the longer the time, the greater the color change, allowing for brighter and clearer specimens. The resins were cytocompatible with NOK-Si, regardless of the printing and post-curing parameters, although residual monomer leaching was affected by the parameters tested. The evaluated resins were cytocompatible; however, variations in the exposure times per layer and post-curing duration affected their roughness, leaching, trueness, and color stability.
Leverage, entrenched managers, and moderating effect of main shareholder’s influence
Authors: Canassa Bruno José , Schwarz Lucas Allan Diniz , Valle Maurício Ribeiro do
Published: February 2025

ABSTRACT This study associated the leverage of Brazilian listed companies with their managers’ search for protection against the risk of main shareholder’s intervention. Although the literature has pointed out that managers might increase leverage in order to protect themselves against takeovers, it had not yet investigated the use of debt as a defense against the risk of intervention by the company’s main shareholder. This research addresses the main issue of corporate governance, i.e. entrenchment resulting from manager’s strengthening and excessive protection. The importance of considering the agency relationship when explaining the capital structure observed in Brazilian companies is reinforced, especially when considering the existence of optimal leverage that might maximize value for shareholders. Panel regressions tested the association of leverage with managerial strengthening and the risk of main shareholder’s intervention for a sample of Brazilian listed companies. Specifically, an interaction model was used in which the observed leverage is a function of strengthened managers, those whose compensation is always higher than expected, given company characteristics and performance, who sought protection against large shareholders who have great influence on the decisions of their companies. The results suggest that, although they have a potential interest in reducing debt discipline, entrenched managers increase debt level in the presence of a large influential shareholder, demonstrating commitment to shareholders. These results highlight the importance of Agency Theory in explaining the capital structure of Brazilian companies, and highlight similarities in the approach to leverage by managers in markets with different characteristics, such as Brazil and the United States of America (USA).

Authors: Bonnet Alberto
Published: February 2025

Resumen Este artículo examina la relación entre las derivaciones de las formas jurídica (de Pashukanis) y política (de los intervinientes en el debate alemán de la derivación del Estado más cercanos a su pensamiento). Las preguntas que lo orientan son las siguiente: ¿qué relación guardan entre sí las derivaciones de esas formas jurídica y política? ¿Pueden ambas derivarse a partir de los mismos puntos de partida? ¿Cuáles son, en caso contrario, los puntos de partida de ambas derivaciones y qué explica la diferencia entre ellos? El artículo analiza críticamente la relación que establecen entre ambas formas Blanke, Jürgens y Kastendiek (primer apartado). Y argumenta a continuación que la derivación de la forma política de Hirsch (segundo apartado) y la derivación de la forma jurídica de Pashukanis (tercer apartado) son (a) diferentes entre sí, (b) presuponen ambas implícitamente que esas formas se derivan de manera diferente, y (c) son compatibles entre sí. El artículo es de índole teórica, naturalmente, perolas preguntas que plantea están cargadas de consecuencias para las teorías marxistas del Derecho y del Estado.

Published: February 2025

Resumo O objetivo deste artigo é apresentar três abordagens atuais sobre o ‘fascismo de novo tipo’ no marxismo contemporâneo para compreender a complexidade envolvida no entendimento deste fenômeno. Logo, o texto está dividido em três seções. A primeira seção trata do fascismo desde a relação capitalismo-democracia-autoritarismo com o foco na forma jurídico-política, partindo-se desde a análise pachukaniana e incorporando os clássicos do marxismo brasileiro. A segunda seção aborda o fascismo desde a relação concreto-abstrato por meio da contribuição do debate da Escola de Frankfurt, em especial, pela crítica do valor e a leitura do Marx ‘exotérico’ e ‘esotérico’ em Kurz. A terceira seção trata do fascismo como ‘antagonismo social em processo’ por meio das ‘formas sociais’ capitalistas cuja base teórica está assentada no debate da derivação do Estado de inspiração hollowayana. Por fim, breves considerações finais são apresentadas.

Authors: Gomes Rodrigo Benevides Barbosa
Published: February 2025

Resumo Lançado em setembro de 2019, o Pacto Educativo Global indica como o primeiro de seus sete compromissos a ‘centralidade da pessoa’. Em outras palavras, o pacto assume o Personalismo como fundamentação filosófico-antropológica da teorização de uma formação integral do homem, isto é, de uma paideia. Dito isso, o artigo se propõe, em primeiro lugar, a apresentar a filosofia personalista partindo da leitura de Paul Ricœur presente na obra Histoire et verité (1955) para, finalmente, se voltar à aplicabilidade do personalismo no contexto socioeducativo.

Authors: Tuba Oskay
Published: February 2025

Pressure ulcers are a significant health issue, particularly among the elderly and immobile individuals, resulting in considerable human suffering and financial costs. They pose a clinical challenge for both healthcare providers and patients, as they can be difficult to heal, expensive to treat, with a significant negative impact on quality of life. Therefore, prevention is crucial.
Here, we report the successful treatment of a 75-year-old male patient presenting with persistent sacral pressure ulcer infection with Vacuum-Assisted Closure (VAC) therapy. This patient had a history of bedridden dementia and a previous cerebral infarction, which predisposed him to persistent deep-pressure ulcers. With effective management, he experienced clinical improvement, highlighting the importance of using VAC therapy in challenging cases.
AMERICAN UNIVERSITY PRESIDENTS’ STATEMENTS ON RUSSIA’S 2022 INVASION OF UKRAINE: А CORPUS-ASSISTED CRITICAL DISCOURSE ANALYSIS
Authors:   Kharkiv University of Humanities “People’s Ukrainian Academy”, Molodcha Natalia S.
Published: February 2025

This study examines how top U.S. university Presidents addressed Russia’s 2022 large-scale invasion of Ukraine in their official statements, aiming to uncover rhetorical strategies and the values guiding higher education leaders in crisis communication. The research employed a corpus-assisted Critical Discourse Analysis framework utilizing tools such as Google Trends, sentiment analyzers, and Voyant. This approach enabled a comprehensive research design, incorporating contextual and textual analyses, communication strategy typologies, and interpretative synthesis to derive conclusions and suggest areas for future research. The findings revealed that a key feature of university leaders’ crisis communication during military conflicts is their ability to balance discursive strategies within the identified genre logic, integrating various arguments, rhetorical techniques, and pragmatic patterns. Criticism of the invasion and penalization of the strategic projects are accompanied by statements of support of students and teachers from both conflicting countries as well as appeals for peace-making efforts. The rhetorical strategies include arguments of logos, pathos, and ethos, along with both positive and negative politeness strategies, and a mix of explicit and implicit speech acts. In the appellative genre, statements confronting the invasion utilize various linguistic devices, such as connotative vocabulary, military terminology, proper names as well as grammatical features like negated active voice constructions, and stylistic elements such as personal reminiscences. This type of communication emphasizes conservative and benevolent values, highlighting the strong commitment of the U.S. university leaders to academic integrity while stressing solidarity and collegiality. Additionally, it underscored diplomatic efforts toward achieving peace. The research offers insights into how higher education leadership navigates communication during wartime, contributing to a broader understanding of strategic and crisis communication.

Authors: Mong Michael , Lipscomb Thomas , Jeanfreau Michelle , Shelley Kyna S. , Wells Kevin , Paprzycki Peter
Published: February 2025

The present study examined search strategies that those in need of mental health services might use to select a provider. Specifically, 176 participants were recruited using Amazon Mechanical Turk and asked to imagine a scenario in which they had taken a job in a new city and had begun feeling isolated and depressed to the point that they decided to seek the services of a mental health provider. Participants responded to a survey that queried their likelihood of using various referral sources based on a five-category Likert-style response scale. An exploratory factor analysis yielded four main factors of potential referrals: promotional sources, nonmedical professional sources, traditional healthcare providers, and personal sources. These factors were then explored using multivariate analyses. The implications of these findings for providing pathways to greater access to mental health services as well as limitations of the study and future research directions are discussed.

Published: February 2025

Background. Current challenges in healthcare include an increase in life expectancy and in medical care (MC) needs, thereby putting pressure on the limited resources of the Russian healthcare system. Efficient allocation of financial resources is becoming a priority. Calculating the cost of MC is considered as a key tool that affects the efficiency of the system. However, the existing calculation methods remain fragmented, which reduces their transparency and limits their application. The need for the unification of approaches to ensure standardization, improve the quality, and increase the accessibility of MC underscores the relevance of the present study.

Objective: to develop a standardized methodology for calculating the cost of MC funded by government sources, aimed at enhancing transparency, standardizing calculations, and supporting a versatile approach in healthcare management.

Material and methods. The study was based on the analysis of regulatory documentation for calculations in the public healthcare sector. The study methodology involved information search techniques, expert surveys, statistical data processing, and economic analysis.

Results. The analysis of existing calculation methodologies revealed their fragmentation, disparities in the level of detail, methods for determining costs, and specific interpretations. The developed standardized methodology included the categorization of costs into direct and indirect, as well as the use of both normative and actual data. The cost of medical services and MC cases were considered the primary calculation units. The methodology was adapted to accommodate various funding sources and regional characteristics.

Conclusion. The suggested methodology enhances the transparency, detail, and consistency of calculations, thereby facilitating effective management of resources within the healthcare system. Flexibility of the approaches allows for further adaptation to meet the needs of different stakeholders within the system.

Authors: Rudakova A. V. , Gaydukova I. Z.
Published: February 2025

Objective: to evaluate clinical and economic effectiveness of netakimab therapy for ankylosing spondylitis (AS) in comparison with other biological disease-modifying antirheumatic drugs (bDMARDs) currently employed in clinical practice in the Russian Federation.

Material and methods. The evaluation of clinical and economic effectiveness was carried out from the perspective of the healthcare system based on the results of a network meta-analysis of randomized clinical trials. Clinical effectiveness criteria included indicators of therapeutic response according to the Assessment of Spondyloarthritis International Society criteria, specifically ASAS20 and ASAS40, as well as by the Bath Ankylosing Spondylitis Disease Activity Index BASDAI50. A time horizon of the study was set at 2 years. Costs of pharmaceuticals were calculated according to the registered maximum retail prices, inclusive of value-added tax. In case of availability of biosimilars on the market, calculations were based on the minimum values of the registered prices.

Results. According to the network meta-analysis, the efficacy of netakimab significantly surpassed that of other bDMARDs or demonstrated a trend towards higher efficacy for AS. The costs per patient achieving an additional response compared to standard therapy without bDMARDs when treated with netakimab appeared 31–77%, 34–80%, and 20–69% lower than those of other bDMARDs, according to ASAS20, ASAS40, and BASDAI50 criteria, respectively.

Conclusion. Netakimab exhibits a higher clinical and economic effectiveness compared to other bDMARDs and may be considered as the preferred therapeutic option in comparable clinical scenarios for active AS, thereby ensuring cost-effectiveness for the healthcare system along with achieving the efficacy criteria compared to the standard treatment regimen. The limitations of the analysis determine the need for further research in this area.
Спорт как зрелище в постковидной реальности
Authors: Алексеева Екатерина Алексеевна , Гуров Олег Николаевич
Published: February 2025

Данное исследование посвящено эволюции спорта в современную эпоху, в период уже сложившейся постковидной реальности. В настоящее время происходит качественная трансформация спорта, изменение всей его многогранной природы во взаимосвязи и во взаимодействии с такими сферами, как технологии, экономика, культура и наука.

В работе исследуется то значимое влияние, которое было оказано коронавирусной пандемией на спортивную индустрию. Ограничения, обусловленные необходимостью бороться с инфекцией, послужили катализатором ускоренного перехода спортивной деятельности к гибридным и виртуальным форматам, и в результате спорт в целом как категория общественной деятельности оказался подверженным глубоким инновационным преобразованиям. В рамках осмысления этих явлений авторы приводят концепцию метапаразитизма с целью проанализировать, в частности, различные аспекты виртуализации спортивных зрелищ.

В качестве конкретного примера также приводится формирующийся и активно развивающийся в современном спорте тренд «фиджитал» (physical+digital). Кроме того, в исследовании применяется концепт киборга для демонстрации того, как технологические достижения делают актуальной тему человеко-машинного взаимодействия конкретно в сфере спорта. Представляемый комплексный анализ позволяет приблизиться к пониманию культурно-философских и общественных аспектов спорта в условиях быстро меняющегося мира и обосновать актуальность дальнейшего исследования перспектив интеграции технологических продуктов в спортивную деятельность, а также развивающегося слияния человека и машины в рамках киборгизации, что в будущем сможет еще более радикально изменить как саму концепцию спорта, так и определение понятия «спортсмен».
Mapping 3D Sedimentary Structures with Joint Inversion of H/V Spectral Ratios and Multimode Dispersion Curves Derived from Ambient Noise—Application to the Xiong‘an New Area, China
Authors: Zhang Youyuan , Lu Laiyu , Maupin Valérie , Qin Tongwei , Ding Zhifeng
Published: February 2025

We present a procedure to use ambient noise recordings to derive high-resolution 3D S-wave velocity models for sedimentary structures by joint inversion of phase velocity dispersion curves (DCs) and horizontal-to-vertical spectral ratios (HVSRs). This procedure is applied to seismological data from a network of 894 stations with a spacing of about 1 km located in the Xiong’an New Area (China), close to Beijing. To obtain the DCs, a Modified Correlation BeamForming method is used to process the noise at subarrays, which enables us to map directly the lateral variations of the phase velocity of the Rayleigh-wave fundamental mode, first overtone, as well as fundamental Love wave, in the total frequency range of 0.3–3 Hz. HVSRs are derived in the frequency range 0.1–10 Hz from the computation of the directional energy density of the three components at each station based on the diffuse field assumption. By combining the DCs obtained by the array-based method and the single-station HVSR curves in a joint inversion, a high-resolution 3D S-wave velocity model of the study area is established down to 2 km depth. The model brings useful information for seismic hazard assessment as well as geothermal energy exploration. It reveals that the thickness of the sediments is highly correlated with the distribution of geologic structures such as highs and lows.

Neste artigo, investigamos a importância da afetividade e discutimos nossas percepções acerca de sua indissociabilidade e relevância ao processo de ensino e aprendizagem do conteúdo matemático. Apresentamos uma breve interpretação da teoria de Chacón (2003) que defende a influência de aspectos afetivos na aprendizagem. Para isso, submetemos alguns dados remanescentes da pesquisa de doutoramento e dialogamos à luz desse referencial teórico. Defendemos que a abordagem do conteúdo matemático por meio das tendências metodológicas em Educação Matemática favorecem a abertura de um canal no qual se pode dar atenção à aspectos afetivos que inexoravelmente emergem durante o processo com ganhos que transcendem o conhecimento matemático, oportunizando aos estudantes serem mais reflexivos, a compartilharem suas limitações, suas inseguranças e a tomarem consciência de qual é o seu conhecimento matemático podendo influenciar positivamente suas concepções e contribuir com a formação cidadã.

Abstract
In this article, we investigate the importance of affectivity and discuss our perceptions about its inseparability and relevance to the process of teaching and learning mathematical content. We present a brief interpretation of Chacón's theory (2003) which defends the influence of affective aspects in learning. Whith this aim, we submit some remaining data from the doctoral research and discuss it in light of this theoretical framework. We argue that approaching mathematical content through methodological trends in Mathematics Education favors the opening of a channel in which attention can be given to affective aspects that inexorably emerge during the process with gains that transcend mathematical knowledge, providing students with the opportunity to be more reflective, to share their limitations and insecurities, and to become aware of their mathematical knowledge, which can positively influence their conceptions and contribute to citizenship development.

Academic and Scientific Thinking on Global Mental Health in Future Healthcare Professionals: A New Challenge Aligned with Contemporary Needs
Authors: Acuña Rodriguez Monica , Fiorillo-Moreno Ornella , Bolaño-Romero María Paz , Cují-Galarza Wendy
Published: February 2025

Global mental health has emerged as a critical area of concern in the 21st century, driven by the increasing prevalence of mental health disorders, the impact of globalization, and the growing recognition of mental health as a cornerstone of overall well-being. The World Health Organization estimates that one in four people will be affected by mental or neurological disorders at some point in their lives, underscoring the urgency of addressing this issue. Despite this, mental health remains underprioritized in many healthcare systems, particularly in low- and middle-income countries, where resources are scarce and stigma persists. Current needs in global mental health include the integration of mental health services into primary care, the development of culturally sensitive interventions, and the training of healthcare professionals equipped to address these challenges. Promoting academic and scientific thinking among future healthcare professionals is a strategic approach to addressing these needs. By fostering a deep understanding of the social, cultural, and biological determinants of mental health, as well as the latest evidence-based practices, future professionals can be better prepared to design and implement innovative solutions. This approach not only enhances their ability to respond to the diverse and complex demands of global mental health but also encourages a proactive mindset toward research and policy development. Ultimately, investing in the academic and scientific training of healthcare professionals can lead to more effective mental health interventions, reduced disparities, and improved outcomes for populations worldwide, aligning with the contemporary needs of a rapidly evolving global landscape.
Recent advances in thyroid orbitopathy treatment: A narrative review
Authors: Alharbi Abdulmajeed
Published: February 2025

Thyroid-associated orbitopathy (TAO), the most common extrathyroidal manifestation of Graves' disease, is marked by orbital inflammatory infiltration and activation of orbital fibroblasts. Key interactions among T cells, B cells, and orbital fibroblasts perpetuate inflammation and tissue remodeling. Particularly, T helper 17 (Th17) cells, a newly identified subset of CD4+ T cells, exhibit significant pro-inflammatory and pro-fibrotic capabilities. Advancements in TAO treatment have significantly improved management strategies. Targeted therapies like teprotumumab, an IGF-1R antagonist, have revolutionized treatment, showing remarkable efficacy in reducing proptosis and improving patient outcomes. Biologics such as tocilizumab, an IL-6 receptor antagonist, and rituximab, a CD20-targeting monoclonal antibody, offer additional options for refractory cases by specifically targeting inflammatory pathways. Traditional nonspecific therapies, including corticosteroids and immunosuppressive agents like mycophenolate mofetil, cyclosporine, and azathioprine, remain crucial in controlling inflammation. Antioxidants such as selenium and statins have shown potential benefits in reducing oxidative stress and inflammation. Innovations in surgical techniques, including endoscopic and minimally invasive approaches for orbital decompression, have enhanced functional and cosmetic outcomes, reducing morbidity and improving patient satisfaction. Supportive measures, such as ocular surface management, smoking cessation, and psychological support, are essential for comprehensive care and improving quality of life.
Impact of environment and genetic factors on myopia in goan children: A behavioral perspective
Authors: Shetty Aksha , Ganguly Anasuya
Published: February 2025

The interaction between lifestyle and family history of myopia plays a vital role in the development and progression of myopia. Understanding this interaction is essential to developing holistic treatment approaches.

An environment-genetic score is a measure that combines information about a person's genetic predisposition and environmental factors that may contribute to the development of a specific condition. This score can help optometrists and other eye care professionals make more informed and personalised decisions regarding the management and treatment of myopia.

A cross-sectional study was conducted in the ophthalmology outpatient department in Goa, India. Children aged between 7 and 15 years were included. Children with less than 0.1 logMAR visual acuity later underwent objective and subjective refraction. A prevalidated questionnaire was used to assess the environmental impact on myopia. Parental myopia was recorded. An Environmental Genetic Index (EGI) can be created to evaluate the risk of myopia in a given population. The difference between the prevalence of myopia in these families is defined as EGI.

152 children were evaluated, of which 64 (42.10%) were females. This study included 75 myopes (49.34%) and 77 emmetropes (50.66%). The prevalence of myopia in the myopic family was 85.71%; in the one-sided-myopic family, it was 60%; and in the non-myopic family, it was 45%. The environmental genetic index was 0.4071, suggesting that genetic factors may play a 40.71% role in the formation of myopia and environmental factors may play a 59.29% role in myopia development.

Genetic factors may have played a 40.71% role in the formation of myopia in the studied population. 12.98% of Myopes lived in a flat, usually in a smaller house, without access to the garden compared to 1.33% of emmetropes. A statistically significant difference was seen in the distance near work was performed; myopes tend to hold their targets closer than 30 centimetres.

INTRODUCCIÓN: La invaginación intestinal (II) es una enfermedad obstructiva potencialmente grave en lactantes y niños menores de 2 años. La adenitis mesentérica es una inflamación de los ganglios linfáticos del intestino, que afecta a niños mayores de 3 años y dentro de sus causas se encuentra apendicitis aguda e infecciones. Reportamos un caso de II en localización infrecuente con asociación a adenitis mesentérica secundaria.
PRESENTACIÓN DEL CASO: Paciente masculino de 7 años de edad, con historia médica de 14 horas de evolución iniciando con dolor abdominal intermitente tipo cólico de inicio difuso y gradual, posteriormente migratorio ubicándose en fosa iliaca derecha, cuadro febril de 38.5ºC, náusea y emesis; sugestivo de apendicitis con 7 puntos de 9 en escala de Alvarado, sin embargo, en la laparoscopía diagnóstica se observaron siete segmentos de II en intestino delgado; se realizó apendicectomía incidental y en el postquirúrgico inmediato se diagnosticó neumonía basal derecha.
CONCLUSIONES: Se encuentra compromiso de siete segmentos intestinales, siendo infrecuente la aparición múltiple, así como su localización en sitios íleo-ileal y yeyuno- yeyunal, además de íleo-cólica. Asimismo, se encuentra relación con neumonía adquirida en la comunidad (NAC) por el hallazgo de adenitis mesentérica secundaria.

Authors: Denac Matjaž , Ošlovnik Tinkara
Published: February 2025

Pri okoljskem upravljanju podjetij se menedžerji srečujejo z več izzivi, med drugim tudi z razvojem okolju primernejših proizvodov. Uporaba načel okoljskega oblikovanja oz. ekodizajna je lahko zahtevno opravilo in predstavlja velik korak k preprečevanju obremenitev okolja pri viru ter s tem prispeva k bolj trajnostni družbi. Za ekodizajniranje proizvodov je na voljo več orodij, ki so različno zahtevna in lahko osvetlijo različne vidike načrtovanja proizvodov. Najbolj celovita orodja ekodizajniranja upoštevajo okoljske obremenitve v vsaki fazi okoljskega življenjskega cikla proizvodov. Ta študija prikazuje primer sistematičnega pristopa k vpeljavi ekodizajna v gradbenem sektorju in je namenjena vsem, ki se ukvarjajo z razvojem izdelkov ali se za ekodizajn zanimajo. Zasnovana je tako, da za razumevanje koncepta ekodizajna ni potrebno predhodno znanje o splošnih postopkih oblikovanja in s tem povezanih tržnih vidikih. Prikazana je uporaba izbranih metod ekodizajniranja proizvodov v podjetju, ki je proizvajalec PVC stavbnega pohištva. Na primeru steklenih oken s PVC okvirjem je bralec voden skozi faze ekodizajniranja proizvoda na način, ki omogoča uporabo istih orodij za okoljsko optimizacijo tudi drugih proizvodov s področja gradbeništva.

Authors: Kerović Jelisaveta , Mežnar Dušan , Roblek Matjaž
Published: February 2025

Umetna inteligenca (UI) je postala sestavni del naprednega poslovanja. V okviru iniciative Industrije 4.0 je namenjena proizvodnim sistemom za podporo proizvodnih procesov od planiranja do izvajanja. Z raziskavo smo ugotavljali stanje na vključenosti umetne inteligence v slovenskih podjetjih, specifično v procesih planiranja proizvodnje. V začetnem delu raziskave smo analizirali definicije o UI iz strokovne literature in o procesih planiranja proizvodnje, na podlagi katerih smo pripravili anketni vprašalnik. Raziskava je obsegala stanje o prisotnosti UI leta 2024 v 21 večjih proizvodnih podjetij v Sloveniji. Na podlagi rezultatov ugotavljamo, da leta 2024 24% proizvodnih podjetij že uporablja UI. Kot glavne razloge za neuporabo UI ugotavljamo interno pomanjkanje strokovnjakov in težko prepoznane koristi za podjetje.

V tem poglavju obravnavamo problematiko ogljičnega odtisa procesa 3D tiskanja ali aditivne proizvodnje, ki je postopek konstruiranja izdelka, plast za plastjo, iz digitalnih modelov z uporabo različnih materialov, predvsem različne vrste plastike. Pregledali bomo okoljski vpliv 3D tiskanja in okoljske vplive v povezanih postopkih (priprava materiala, transport, ravnanje z odpadnimi izdelki). V prispevku preučujemo proizvodnjo, uporabo in odstranjevanje, pri čemer se osredotočamo na porabo energije, vire materiala in ravnanje z odpadki. Poleg tega ta študija vključuje primerjalno oceno med 3D tiskanjem in alternativnimi metodami proizvodnje, da se ugotovi njihov posamezen okoljski vpliv. S celovito analizo želimo prispevati k razumevanju izzivov in priložnosti trajnostnih vidikov 3D tiskanja s plastiko. Z oceno dejavnikov, kot so izraba virov in emisije, si prizadevamo zagotoviti dragocene vpoglede v trajnostne posledice 3D tiskanja s plastiko. Ugotovljeni rezultati prispevajo k širši razpravi o prednostih in slabostih 3D tiskanja v primerjavi z drugimi metodami izdelave.

Published: February 2025

Zahteve po novih proizvodih, ki so tudi vedno bolj kompleksni, neprestano naraščajo, podjetja pa se morajo na te zadeve ustrezno odzvati z razvojem in proizvodnjo ustreznih proizvodov ob pravem času in po dovolj ugodni ceni, da ne izgubijo konkurenčne prednosti. Čeprav je razvoj novih proizvodov neizbežno povezan s tveganjem, ga je mogoče zmanjšati z uporabo enega izmed referenčnih modelov za obvladovanje aktivnosti razvoja novih proizvodov. V ta namen v poglavju predstavimo pregled razvoja referenčnih modelov razvoja novih proizvodov. V nadaljevanju se osredotočimo na predstavitev sodobnih tehnologij, ki jih podjetja vse pogosteje vključujejo v proces razvoja novih proizvodov. Namen njihovega vključevanja je predvsem v skrajšanju potrebnega časa za razvoj novih proizvodov in znižanju s tem povezanih stroškov. Predstavimo namen vključevanja sodobnih tehnologij ter podamo pregled izzivov, s katerimi se podjetja pri tem srečujejo, in prednosti, ki jih podjetja s tem lahko dosežejo.
