Advanced Copula-based Methods for Nonparametric Detection and Characterization of Wideband Radar Signals
Authors: Bokal Zhanna
Published: November 2024

This paper introduces advanced copula-based methods for the nonparametric detection and characterization of wideband radar signals. The research focuses on developing signal detection algorithms that are invariant to changes in the probability density function of the sounding or reflected signals, employing multiscale analysis techniques and copula-based statistics. Two primary approaches are explored: multiscale analysis using wavelet transforms and rank-based signal detection with copula-based ambiguity functions. Simulation results confirm the effectiveness of the proposed approaches. The research demonstrates that integrating rank-based methods with copula-based statistics significantly improves the detection and analysis of wideband radar signals, particularly in complex scenarios where signals exhibit intricate dependency structures. This comprehensive detection framework is well-suited for handling high-dimensional radar signal data, enhancing accuracy and reliability under varied conditions. Future work will focus on optimizing copula selection and permutation strategies to further improve performance.

Алгоритм обчислення частоти напруги в електромережі з використанням квадратурних складових
Authors: Петросян Р.В.
Published: November 2024

У науковій статті вирішувалась важлива науково-технічна проблема – зниження похибки обчислення частоти напруги в електромережі. Обчислення значення частоти напруги має важливе значення, оскільки це дає змогу забезпечити надійність і стабільність роботи енергетичних об'єктів. Тривала робота обладнання при значному відхиленні частоти напруги від номінального значення призводить до його підвищеного зносу та передчасного виходу з ладу. Також невідповідність частоти номінальному значенню може бути причиною до виникнення додаткових похибок під час вимірювання інших параметрів енергетичних об'єктів.
В основу методу покладено обчислення частоти напруги в електромережі з використанням квадратурних складових. В ході роботи було запропоновано структурну схему обчислення частоти напруги з використанням цифрових фільтрів. Також було виконано синтез цифрових фільтрів. Для перевірки отриманих результатів проведено моделювання на комп'ютері з використанням мови програмування Python. Запропоновано алгоритм обчислення частоти напруги в електромережі.

Published: November 2024

Метою даного дослідження є доведення корисності висновків теорії перколяції для оцінки зв'язності мережі Інтернету речей. Ймовірність наявності маршруту між двома парами вузлів визначає зв’язність мережі. Коли ця ймовірність наближається до одиниці, мережу вважають зв'язною. Наприклад, можна використовувати пошук найкоротших шляхів між усіма парами вузлів (вершинами графа, що описує мережу) для оцінки зв’язності в конкретній ситуації. Дві причини ускладнюють розв’язання цієї проблеми. По-перше, обчислювальний ресурс, необхідний для цього, зростає пропорційно до n3, де n – кількість вершин графа. По-друге, існуючі аналітичні підходи зазвичай спрямовані на конкретні випадки, а не на велику кількість вузлів.
У статті запропонована модель мережі у вигляді решітки, яка слугує логічною основою для структурування зв'язків між вузлами, розташованими в різних приміщеннях. Форма решітки контролюється плануванням будівлі. Отримана модель дозволяє оцінити ефективність каналу зв'язку за допомогою оцінки ПСП та загального відношення СШ для вузлів мережі. Використання моделі дозволяє впевнено стверджувати, що в сучасній багатоповерховій структурі, якщо вузли стратегічно розміщені в кожній кімнаті, цілком можливо створити бездротову мережу зв'язку. Крім того, якість радіоканалу дозволяє використовувати швидкості передачі даних, які відповідають найвищим стандартам сучасних технологій.
JUSTIFICATION OF THE FEASIBILITY OF RECONSTRUCTING ONE TRACK OF A DOUBLE-TRACK SECTION TO THE EUROPEAN STANDARD GAUGE (1435 mm)
Authors: Kurhan Mykola , Kurhan Dmytro , Baidak Serhii , Novik Ruslan , Khmelevska Nela
Published: November 2024

The article systematizes scientific developments concerning the design and reconstruction of railway lines to the European  track gauge of 1435 mm. Drawing on the experience of European countries, the study investigates the conditions under which  it is feasible to implement a project solution involving the reconstruction of a double-track section into two single-track sections  with different gauges: one track  remains at 1520 mm, while the other is converted to 1435 mm. The research was conducted  using graph-analytical modeling methods. The methodology involves the use of a developed mathematical model that allows  for evaluating different scenarios of line capacity using transportation mastery graphs. The study forecasts  transportation  volumes under pessimistic, rational, and optimistic scenarios, under which the reconstruction of a double-track section into two single-track sections with gauges of 1435 mm and 1520 mm may be justified. A scientific approach  is proposed, enabling the  evaluation of various capacity scenarios for two single-track sections with gauges of 1520 mm (existing) and 1435 mm  (reconstructed), using graph-analytical modeling methods. Based on the results of domestic and foreign scientific  developments, potential solutions are outlined for the construction of European standard railways in Ukraine, considering  existing infrastructure, geopolitical, topographical, and other conditions. The advantages of this solution include cost savings  (as one track does not need to be rebuilt), maintaining connections with countries that use the 1520 mm gauge, and the ability  to organize train movements with different track gauges.
RESENHA DE: “THE HUNDRED YEARS WAR REVISITED ” POR FERNANDO PEREIRA DOS SANTOS
Authors: Pereira dos Santos Fernando
Published: November 2024

This highly valuable book closely scrutinizes a variety of documents produced by the Hundred Years War main contenders roughly between the early 1300’s, a few decades before Edward III declared his intent to prosecute a war against his cousin Jean II for the crown of France, until a little bit after 1453, when Calais became the last remaining possession under Henry VI’s control. Pondering on the historical research in the last half century, the world leading expert Professor Anne Curry points out in a richly concise introduction the clear attempt to dialogue with Kenneth Fowler’s The Hundred Years War, a substantial volume published back in 1971. All in all, she successfully highlights the advancements achieved on investigating objects thoroughly laboured by employing prime methodologies of research, bringing up such a pleasant reading to experts interested on the several aspects of the longstanding conflicts carried out by both crowns. Structured in nine chapters, in similar fashion to Professor Fowler’s list of contents, it covers a broad range of classical topics from financing of war and political tensions between England and France to the composition of armies, navies and the perspectives of cultural approaches regarding understandings of the code of chivalry, the direct insights of first-hand accounts of warfare and the pivotal role played by the Church in regulating violence, administrating war logistics and providing support for either the Plantagenet, Lancaster or Valois king of the time not only with supplies, but also with warriors.
DE ILHA EM ILHA RUMO AO PARAÍSO. ENSAIO COMPARATIVO ENTRE BRANDÃO E AMARO
Authors: Franco Júnior Hilário
Published: November 2024

Do vasto corpus medieval de viagens em vida ao Paraíso terrestre, as divergências e convergências entre duas delas, a de São Brandão e a de Santo Amaro, fornecem informações e pistas de reflexão interessantes para o historiador. No plano da visão de mundo de cada relato, é pleno de implicações o fato de o primeiro daqueles peregrinos procurar o Paraíso navegando para ocidente, o outro para oriente. No plano religioso, é significativo que na Navigatio sancti Brendani o santo reporte-se diretamente a Deus, enquanto o personagem-título do Conto de Amaro recorre à intermediação da Virgem. No plano social, chama atenção que Brandão visite o Paraíso com seus companheiros e Amaro sozinho, expressão do individualismo que ganhava terreno desde o século XII. Enfim, as diferenças entre os dois textos derivam evidentemente de seus locais, datas e autores específicos, o que apenas enfatiza o denominador comum, se não universal, de todo homem sonhar com uma terra melhor do que a sua.
FRANCISCO DE ASSIS E A CULTURA DA REFORMA: APONTAMENTOS NO SPECULUM PERFECTIONIS MINUS E NO SPECULUM PERFECTIONIS
Authors: Tavares Magalhães Ana Paula
Published: November 2024

Francisco de Assis a Ordem Franciscana, criada no século XIII, devem ser encarados a partir de uma perspectiva reformista, ou seja, como continuadores de uma tradição que remonta aos séculos XI e XII. Sendo assim, propõe-se uma perspectiva da espiritualidade franciscana a partir da religiosidade laica que se originou da popularização da fé a partir do movimento monástico. Neste artigo, analisamos duas obras atribuídas a frades que partilharam do primeiro convívio com Francisco – obras não relacionadas à oficialidade e, por essa razão, mais permeáveis aos movimentos sociais da época.
“EMOTIONAL PERFORMANCES” IN ANCIENT GREECE: THE MOURNING THROUGHTHE BODY (8TH-5TH CENTURIES B.C.)
Authors: Jourdan Camila
Published: November 2024

Pain and the grieving process for men and women demand a transformation of the body: crying, chanting the funeral lamentation, getting dirty and cutting hair are part of a social presentation of mourning for the deceased.  Considering these issues and having in mind a History of Emotions, we propose a reflection on the “emotional performance” in funeral contexts, with emphasis on the speeches and practices of imputating of mourning in the visual sphere, that is, the transformation of their bodies before society. In this article we analyze the Homeric epics and list some tragedies in order to understand the mourning behavior of men and women in Hellas and their relationship with the body as a vector of an “emotional performance”.
Groundwater Pollution Concentration Estimation with Modified Kalman Filter Method
Authors: Estuningsih Nenik , Fatmawati Fatmawati
Published: November 2024

Groundwater quality is very important for human health. Estimation of groundwater pollution concentration to determine groundwater quality is necessary. The concentration of groundwater pollution is estimated using the modified Kalman filter method. The modified Kalman filter method is a method that collaborates the Kalman filter estimation algorithm with the model order reduction method. The model order reduction method used in this research is the LMI (Linear Matrix Inequality) method because the model reduction error using the LMI method is the smallest error compared to the reduction error using the Balanced Truncation method or the Singular Pertrubation Approximation method. The modified Kalman filter method is used in order to obtain accurate estimation results with a short computation time. It is found that the implementation of the Kalman filter algorithm in the original system as well as the implementation of the modified Kalman filter method of the reduced system with the LMI method produces very good estimates, close to the real state variable. The estimation of the original system takes longer time than the reduced system.
Semantic Dispersion In Translation Of The Qur'an Into Malay/ التَّشتُّت الدَّلالي في ترجمة القرآن إلى اللُّغة المالايوية
Authors: Yeob Shamsul Jamili Bin , Balki Nur Nazwan , Alosman Abdulrahman
Published: November 2024

The issue of semantic dispersion has captured the attention of researchers in the field, and they attribute its reasons to translators’ negligence in highlighting the connotations correctly. This is a result of their sole reliance on literal or meaningful translation that consequently led to ambiguity surrounding the meanings and semantic style of Quranic verses. This study aimed to analyze the process of translating words in selected Quranic verses into the Malay language by different translators of the holy Qur’an by identifying the main problems involved in the translation process. Comparisons were made between the translations above by selecting several controversial verses that lead to semantic dispersion. The current study employed the descriptive analytical comparative approach, where the researchers described the approaches in translating the holy Qur’an from the Arabic language into the Malay language. Three translations were compared, namely the Al-Humaira translation (printed version) and the other two translations, which are digital, namely Surah.my and The Noor, because the Malay community commonly uses them. Al-Humaira is the primary source in this study, where examples of selected verses were analyzed and compared with the other two translations. Several findings were reported in this study, with the most important being that there are glaring differences with significant gaps between the translation processes of the translations above, where the translation of Al-Humaira was better and more accurate than the other two translations. Another finding in this study is that the difficulties facing translators are related to the connotations of meanings resulting from dimensions of language such as culture and connection to context, difficulties that cast a shadow over all translation processes. Hence, it is almost impossible to convey the meanings of the holy Qur’an with complete accuracy despite the excellent skills of translators in the field.
Arabic Vocabulary And Its Cultural Influences On The Colloquial Tamil Language: Special Reference To South Tamil Nadu India/ المفردات العربية وتأثيراتها الثقافية في اللغة التاميلية العامية : جنوب ولاية تاميل نادو في الهند أنموذجا
Authors: Kadir K J Mohideen Abdul , Mohideen H.L.M.
Published: November 2024

Language is vital for exchanging opinions and ideas, expressing feelings, and fulfilling daily needs. Arabic stands out among other languages due to its various advantages and features. Tamil Nadu, one of the states in India, is known as the historical frame of the Dravidian civilization, one of India's oldest. It is situated in the southernmost part of Asia. Tamil Nadu's residents speak Tamil, an ancient and expressive language celebrated for its rich literature and esteemed position among Indian languages. Tamil Nadu's global prominence stems from its historical oceanic and commercial connections. Centuries ago, the state actively traded with China, Babylonia, Rome, the Levant, the Turks, and, notably, the Arabs. These trade interactions facilitated vigorous import-export activities and improved cultural exchange and integration among diverse peoples. This study focuses on the influence of the Arabic language on Tamil, particularly in contemporary usage, where many Arabic words have been integrated into Tamil vocabulary. This research emphasizes the everyday use of Arabic terms, especially in fields such as law, exemplified by terms like amal, asal, bark, taraf, waterish, wakeel, and wayeetha, etc. It examines the linguistic and cultural similarities and shared usage of words between these two distinct languages. The methodology adopted is qualitative. The primary data was collected through personal interviews and original texts. Secondary data were obtained from related books, and scholarly works and data were analyzed. This study concluded that Arabic influence in colloquial Tamil, especially in southern Tamil Nadu, needs more extensive research. The persistent Arabic influence on Tamil civilization and cultural practices is frequently mistaken for indigenous Tamil elements in academic and administrative contexts. Arabic words used in Tamil have their roots and origins, emphasizing their originality in the Arabic language rather than being borrowed from Tamil.
Cartografias de Pesquisas com Crianças em Educação Matemática: uma Revisão de Trabalhos Publicados no Brasil

Published: November 2024

Visando cartografar modos pelos quais as crianças comparecem como objeto na pesquisa em Educação Matemática, revisamos trabalhos publicados a partir de 2012 em quatro periódicos e em anais de dois dos eventos mais importantes da área no Brasil. Foram selecionados os trabalhos que tratavam da infância ou que faziam pesquisa com crianças. De nossa seleção resultaram 60 trabalhos, sendo 46 publicados em periódicos e 14 em anais de eventos. Discutimos os seguintes pontos: ao fazer pesquisa com crianças, a Educação Matemática não vem problematizando explicitamente concepções de infância e criança que guiam suas reflexões; os trabalhos operam com uma equivalência entre as noções de criança e aluno; o cognitivismo de inspiração piagetiana é o regime hegemônico de leitura da atividade matemática das crianças; as pesquisas vêm promovendo uma antecipação do uso de ferramentas didático-metodológicas da Educação Matemática para crianças cada vez menores, com destaque para trabalhos que utilizam a Educação Estatística e a Modelagem Matemática na Educação Infantil. O artigo aponta para a necessidade de recolocar o problema da infância em Educação Matemática de modo a dar acento aos processos de criação que escapem a os regimes hegemônicos de produzir subjetividades das crianças.

Venous thromboembolism [VTE] is common in pregnant females but limitations for timely diagnosis using non-invasive techniques delays the diagnosis and cause increased morbidity. Inability to use radiological methods and physiological increase of D-dimer values in pregnancy inhibits the use of non-pregnant reference ranges of D-dimer.
Benefits and Risks of Menopausal Hormone Therapy
Authors: O Mueck Alfred
Published: November 2024

Menopausal Hormone Therapy (MHT) (estrogen/progestogen) is used to treat menopausal complaints and to prevent osteoporosis. Additional preventive benefits are reduction of cardiovascular disease, reduction of colon cancer, and perhaps also Alzheimer’s disease, if started within a “window of opportunity”, i.e. in perimenopause or within 6-10 years after menopause. Primary indication for progestogen addition is to avoid the development of estrogen-dependent endometrial cancer, i.e. addition not recommended in hysterectomized women. Two main schedules, sequential- or continuous-combined estrogen/progestogen regimens, are used. For optimizing menstrual regulation detailed recommendations are given
Insights from Portuguese Nephrologists and Rheumatologists Concerning the Treatment of ANCA Vasculitis
Authors: Ferreira Inês , Águeda Ana , Belino Carolina , Schau Bruno , Rovisco João , Ferreira Carina
Published: November 2024

Introduction: Antineutrophilic cytoplasmic antibodies-associated vasculitis (AAV) encompasses granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis. These rare diseases are characterized by an exaggerated immune response in blood vessels, leading to inflammation, vascular injury, ischemia, and necrosis of affected tissues and organs. Despite the existence of European recommendations for treating AAV, their implementation in Portugal remains unclear.Methods: To address this gap, an online Delphi panel was conducted involving 55 Portuguese nephrologists and rheumatologists, representing the main specialties involved in the management of AAV. The primary objective was to assess the level of consensus regarding the treatment of AAV in Portugal and the application of European recommendations in daily clinical practice. The specialists evaluated 29 statements formulated by a group of Portuguese experts with extensive experience in AAV, addressing key aspects of AAV management, rated on a 4-point Likert scale. Consensus was defined as > 70% of responses either strongly agreeing or strongly disagreeing with a statement, while the majority level required > 70% agreement or disagreement.Results: After one round, no statement reached consensus globally, and eight out of the 29 statements did not achieve a qualified majority. Nonetheless, this study demonstrates a high level of agreement within each medical specialty, due to the distinct characteristics of the patient populations treated by each specialty. While the results suggest partial adherence to European recommendations, they also highlight the need to standardize clinical practices for AAV treatment in Portugal.Conclusion: This study underscores the importance of aligning national practices with established European recommendations to ensure the best outcomes for patients with AAV.

Análise das categorias de apego ao lugar rural
Authors: Morais Manoela , Binotto Erlaine
Published: November 2024

Um lugar compreende um espaço geográfico resultante da ação humana e responsável por moldar comportamentos. Conexões formadas com lugares considerados especiais são denominadas apego e acompanham indivíduos em todos os estágios da vida. Proprietários rurais constituem um grupo que consideram a sua terra um lugar único. Neste sentido, o objetivo deste artigo é identificar categorias de laços emocionais presentes na relação indivíduo e o lugar rural. A metodologia é baseada numa revisão bibliográfica em onze estudos publicados nas bases de dados internacionais. Da análise dos resultados, seis categorias emergiram a partir do confronto teórico da literatura com os achados dos artigos analisados. As categorias apresentam vínculos estabelecidos entre indivíduos-lugar rural: a categoria ambiente compreende características naturais e físicas; a categoria comunidade inclui a relação com pessoas; a categoria enraizamento é composta pelos sentimentos despertados pelo lugar; a categoria família integra a história construída no lugar; a categoria retorno financeiro é composta pela renda obtida com o lugar; e a categoria vida rural considera a atração pelo estilo de vida no lugar. Com efeito, tem-se que esses resultados sinalizam para uma importante agenda de pesquisas futuras sobre o apego ao lugar no sentido da demarcação de um horizonte teórico-conceitual promissor sobre o tema.
Pecuária sustentável no Pantanal: desafios e oportunidades para os produtores locais de ovinos
Authors: Bitencourt Taner Douglas Alves , Facco Gilberto Gonçalves , Neto José Francisco dos Reis , Matias Rosemary
Published: November 2024

A pecuária é atividade tradicional do Pantanal, bioma que se estende por Mato Grosso do Sul e Mato Grosso e é reconhecido, pela UNESCO, como patrimônio natural mundial. Tal atividade enfrentou desafios para se adequar à legislação ambiental e atender aos interesses dos diversos atores sociais na região. Este artigo se propôs a examinar a ovinocultura na planície inundável do Pantanal como uma alternativa de produção sustentável à pecuária tradicional. A ovinocultura é vista como atividade com o potencial de equilibrar a conservação desse bioma, com o desenvolvimento socioeconômico dos produtores locais. Empregou-se a pesquisa qualiquantitativa como metodologia, que se baseou em documentos oficiais, dados estatísticos, entrevistas e em três últimos censos agropecuários. Indicou-se que a ovinocultura pode gerar renda, emprego e agregar valor aos produtos do Pantanal, além de contribuir para a preservação da biodiversidade e da cultura local. Porém, a atividade enfrenta obstáculos, como a falta de infraestrutura, assistência técnica, crédito e incentivos fiscais. A regulamentação e implementação da Lei do Pantanal pode impactar positivamente a ovinocultura, em razão dos artigos e incisos alinhados com a produção pecuária sustentável. É necessário um planejamento estratégico integrado que leve em consideração as especificidades do bioma e dos produtores, bem como a valorização das marcas locais, por meio de indicações geográficas ou selos de qualidade.

In a series of publications, we attempt to demonstrate the prophylactic role of bromhexine hydrochloride (BHH) and the curative role of high colchicine doses against COVID-19. Effects of long-term prophylaxis with BHH are presented in two cases of elderly women with severe comorbidity. After long-term prophylactic use of BHH from 3 to 6 months, one does not get sick from COVID-19, and the other passes it almost asymptomatically, even though all their family members fall ill. The dramatic healing effect of colchicine was demonstrated in a family in which both spouses became ill with COVID-19 almost simultaneously. They are treated in different hospitals, and where colchicine is administered in high doses, the patient recovered. The other patient developed complications and died on standard treatment without high doses of colchicine. An outpatient accidentally overdosed on colchicine (12.5mg). The therapy was stopped immediately. Clinically, on the third day, there are absolutely no symptoms. These cases reaffirm the prophylactic effect of BRH and the curative effect of high-dose colchicine

Background. One of the most important prognostic factors in periampullary and pancreatic cancers is perineural infiltration, whose preoperative detection could be decisive in selecting which patients should not undergo upfront surgery. We evaluated CA 19.9 and the Neutrophil-to-lymphocyte ratio (NLR) as preoperative predictors of perineural invasion (PNI). Methods: Retrospective analysis including patients with periampullary and pancreatic cancers who underwent curative resection from January 2013 to August 2023 in our institution. A univariate analysis and multivariate analysis were performed to analyze the association between the CA 19.9 and NLR with the existence of PNI. Results: A total of 136 patients were included in the study. PNI was observed in 95 (69.9%) patients. The selected cut-off points were NLR: 2.2 and CA 19.9: 37 U/mL. In univariate analysis, NLR (p=0.001) and CA 19.9 (p=0.006) were statistically significantly associated with PNI. In multivariate analysis, baseline NLR levels (p=0.012; OR: 1.95; 95%CI: 1.16-3.29) as well as CA 19.9 levels (p=0.026; OR: 1.67; 95%CI: 1.06-2.64) remained independent prognostic factors for PNI. The area under de ROC curves was 0.67 for CA 19.9 (p=0.004) and 0.72 for NLR (p<0.001). A sensitivity of 65.9% with a positive predictive value of 81.7% were obtained for CA 19.9, and a sensitivity of 62.1% with a positive predictive value of 84.3% were achieved for NLR. Conclusion: Preoperative CA 19.9 and NLR levels seem to be good predictors of PNI. In patients with normal levels of CA 19.9, preoperative NLR above of 2.2 should be an indication for neoadjuvant therapy.

The human gastrointestinal microbiota plays a vital role in maintaining host health and preventing diseases, prompting the creation of simulators to replicate this intricate system. The Simulator of the Human Intestinal Microbial Ecosystem (SHIME®), a multicompartment dynamic simulator, has emerged as a pivotal in vitro model for studying the interactions and interferences within human gut microbiota. The continuous and real-time monitoring hallmarks, along with the programmatically flexible setup, bestow SHIME® mimicking the entire human intestinal ecosystem with high dynamics and stability, allowing the evaluation of various treatments on bowel microbiota in a con-trolled environment. This review outlines recent developments in SHIME technology, highlighting its applications in food and nutritional science, drug development, and gut health research. Additionally, the prospect of SHIME integrating with other advanced technologies is also discussed.

Special Issue on Design and Manufacturing for Environmental Sustainability
Authors: Mitake Yuya ,   Editorial Office, Umeda Yasushi
Published: November 2024

This is the seventh special issue on Design and Manufacturing for Environmental Sustainability. As the first special issue on the topic was issued in 2009, the topic has a fifteen-year history in this journal. Environmental sustainability was recognized as important for manufacturing even at that time, which is why the special issue was started in this journal. The seriousness of this topic has been increasing not only in Europe but also in Japan and other countries. A recent critical trend has been the way in which companies’ attitudes toward this issue, including their positions on carbon neutrality, a circular economy, and biodiversity, determine their value. Furthermore, particularly striking trend is the promotion of various policies to realize a circular economy, including the adoption of international standards for a circular economy and new eco-design regulations in Europe. These movements indicate the need to transform production and consumption in society as a whole beyond the boundaries of individual companies and industries.

The seventh special issue contains seven well-written papers. The papers cover the following topics:

- Circular economy

- Life cycle design and management

- Environmentally conscious design of products and services

- Low-energy and low-emission manufacturing

- Closed-loop supply chain management

- Sustainable consumption and production

From the fifteen-year history of this special issue, we have been able to learn viewpoints specific to the series in this journal.

Most of the papers, revised and enhanced in response to the editor’s invitation, were originally presented at EcoDesign 2023, the 13th International Symposium on Environmentally Conscious Design and Inverse Manufacturing, held in Nara, Japan.

The editor sincerely thanks the authors and reviewers for their contributions in making this special issue possible. We hope that these articles encourage further research on design and manufacturing for environmental sustainability.
Hybrid Simulation Model of Lifecycle Simulation and Replacement Simulation Considering Carbon Lock-In by Coal-Fired Power Plants

To meet the temperature goal set by the Paris Agreement, cumulative CO2 emissions must be kept below 300 GtCO2. Road transportation accounted for approximately 18% of the CO2 emissions from fuel combustion in 2017. Electric vehicles (EVs) have been rapidly adopted by environmentally conscious consumers in many countries to reduce CO2 emissions. EVs have lower emission intensities than do internal combustion engine vehicles (ICEVs) in most parts of the world, except where the penetration of renewable energy is low in the energy production mix. In such places, the CO2 emissions of EVs are larger than those of ICEVs. Despite the obvious need to increase renewable energy sources to reduce CO2 emissions, Japan and many other countries around the world have yet to shift away from fossil fuels. This is due in part to carbon lock-in, which refers to prior decisions related to technologies and infrastructure that constrain the implementation of better paths toward low-carbon technologies. Coal-fired power plants are the most problematic in terms of carbon lock-in because of their high carbon intensities and long physical lives. In addition, because carbon lock-in by coal-fired power plants has a significant impact on the embodied CO2 intensity of grid power, it impacts society through products that use electric power. In this study, we propose a hybrid simulation model of lifecycle simulation and replacement simulation, considering carbon lock-in by coal-fired power plants. In the replacement simulation, we simulated the replacement of end-of-life coal- and oil-fired power plants with renewable energy power plants using a probability called the lock-in rate and estimated the changes in the embodied CO2 intensity of grid power in Japan. In the lifecycle simulation, we evaluated cumulative CO2 emissions from entire product lifecycles of ICEVs and EVs based on three different EV diffusion scenarios. The results showed that the lock-in rate of coal-fired power plants strongly affects the decarbonization effect due to the market diffusion of EVs.

Given the rapid growth of digital technologies, the use of information systems (ISs) is increasingly important for businesses positioned within the circular economy (CE). When designing an IS for such businesses, it is essential to simulate how the IS affects the life cycle (LC). However, existing research has not yet addressed this issue. For example, life cycle simulation (LCS) mods an LC and evaluates the economic profit and environmental impact of a product across its entire LC but does not explicitly model the IS and the effect from IS on LC is not simulated clearly. In this study, we propose a modeling method (E-DFD) and a simulation system (ISS) for modeling and simulating the IS. In the E-DFD and the ISS, we model and simulate an IS as a set of functions. Additionally, we propose a method that facilitates cooperation between IS simulations and LC simulations, allowing the effect of IS functions on LC to be evaluated. To validate the effectiveness of the ISS and the simulation method, we describe a case study that targets a new servitized business model with refrigerators. In the case study, we considered three patterns of LCs and two IS patterns with different functions for comparing the entire LCs and how the economic profit and environmental impact are changed depending on the difference in IS functions. In this case study, the IS and LC simulations identify how differences in IS functions affect the economic service provider’s profit, as well as the CO2 emission from the entire LC. Although our simulation method covers the entire LC, the functions of the IS focused on the use process in the case study. Therefore, further case studies targeting the LC processes, except the use process, are important for future work. In addition, developing methods for modeling and simulating the economic and environmental aspects of an IS is required.
