Legality and Commitment
Authors: Jiménez Felipe
Published: February 2025

Many philosophers believe there is no general, content-independent duty to obey the law. Yet at least some (and perhaps many) citizens and officials believe law makes a real difference—independently of its content and of prudential considerations—regarding what they should do. This paper offers an argument that vindicates the latter belief, even if skeptics are right in thinking that law cannot generate a general duty to obey. Under this argument, whether law makes a real practical difference, independently of its content and of the sanctions threatened for its violation, can turn on whether individuals have adopted a commitment to law. The paper provides an account of such commitments and their impact on reasons for action. As I argue, the fact that a legal system complies with the demands of the rule of law is one important reason why individuals ought to, or at least might, adopt such a commitment. Compliance with the rule of law is thus not normatively irrelevant, even if it does not directly ground a moral duty to obey.
Ours Is a Speciesist World, Really
Authors: Jaquet François
Published: February 2025

To date, much of the speciesism debate has centered on an ethical question: Can speciesism be justified, or is it immoral, as the analogy with racism suggests? Another question has received less attention: How prevalent is speciesism? Animal ethicists have largely assumed that speciesism is pervasive in our societies. After all, almost everyone routinely treats animals in ways they would never treat fellow humans. This widespread assumption is now being challenged. Some philosophers are beginning to question whether speciesism is an accurate diagnosis for our conduct. This paper defends the orthodox view against such critiques. It refutes three challenges to the existence of speciesism—one posed by Travis Timmerman, another by Shelly Kagan, and a third inspired by Stijn Bruers. Some of these arguments rely on a flawed understanding of speciesism; all generate implausible empirical predictions.
PECULIARITIES OF TEACHING PHYSICS AND ASTRONOMY AT THE FACULTY OF PHYSICS IN THE CONDITIONS OF DISTANCE LEARNING
Authors: Makarovsky M. O. , Savchenko O. M.
Published: February 2025

Development of high quality teaching remotely is currently at the forefront of higher education developments. Particularly challenging is remote delivery of the teaching programs that require deep understanding of complex scientific phenomena, as well as development of practical skills and professional competencies. In this work, we discuss the experience of remote delivery of Physics degree. It is noted that different approaches are needed for different teaching elements. Based on this, we make recommendations for approaches to enhance student experience and to enable successful completion of the degree programs.

Remote defense of the diploma projects in the format of research conference (using Zoom, Skype, GoogleMeet and other video communication) showed that this stage of the educational process is successfully implemented and is almost identical to the face-to-face defense. Consultations (on training courses, research projects, diploma projects) can be conducted remotely.

When conducting written assessments of learning: tests, quizzes and examinations in the distance mode (using standard procedures such as distribution of questions and tasks), it is quite difficult to control the quality of students' performance, since there are opportunities for use various sources of information. A test system can provide a suitable substitute.

The experience of conducting lectures and practical classes in the distance mode has shown that the lecturer does not have the feedback that occurs in classroom teaching. The lecturer is unable to interact with the audience, since students hardly ask questions and during the lecture they can go about their own business rather than listen to the lecturer.

Published: February 2025

Ketahanan pangan menjadi salah satu isu penting dalam pembangunan daerah, khususnya di Kabupaten Bandung Barat yang berkontribusi besar terhadap produksi pangan di Provinsi Jawa Barat. Kecamatan Gunung Halu memiliki lahan pertanian yang luas, tetapi produktivitasnya terhambat karena sistem irigasi yang belum memadai. Penelitian ini bertujuan untuk menganalisis strategi Dinas Pekerjaan Umum dan Tata Ruang (PUTR) dalam meningkatkan ketahanan pangan, mengidentifikasi faktor pendukung dan penghambat, serta menelaah upaya yang telah dilakukan untuk mengatasi hambatan ketahanan pangan. Teori strategi yang digunakan adalah model strategi Jack Kooten (1991:81), yang terdiri atas empat pendekatan, yaitu strategi organisasi, strategi program, strategi pendukung sumber daya, dan strategi kelembagaan. Penelitian ini bersifat kualitatif dengan pendekatan fenomenologi. Data dikumpulkan melalui wawancara, observasi, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa Dinas PUTR telah menerapkan berbagai program pembangunan irigasi untuk mendukung produktivitas pertanian di Kecamatan Gunung Halu. Namun, tantangan yang dihadapi mencakup kondisi geografis wilayah yang kompleks serta keterlibatan masyarakat yang masih terbatas dalam pengelolaan sistem irigasi. Faktor pendukung peningkatan ketahanan pangan meliputi lahan pertanian yang luas dan forum Musyawarah Perencanaan Pembangunan (Musrenbang) yang berfungsi sebagai sarana pelaporan jika terdapat irigasi yang rusak. Strategi yang diambil Dinas PUTR mencakup pengelolaan sumber daya air dan optimalisasi sistem irigasi untuk meningkatkan hasil pertanian. Penelitian ini diharapkan dapat menjadi referensi bagi pemerintah daerah dalam mengembangkan strategi yang lebih efektif untuk mencapai ketahanan pangan.

Attempt CPR—language matters inside our hospitals
Authors: Pegg Tammy , Psirides Alex , Berry-Kilgour Niamh , Goodwin Jane , Lakin Joshua , Grundy Kate
Published: February 2025

The terms cardiopulmonary resuscitation (CPR) and resuscitation have been used non-specifically and interchangeably. To provide
clarity and transparency to clinicians and patients when facilitating conversations about what treatments are warranted and wanted if
clinical deterioration occurs in the hospital, CPR must be reframed as its original, official definition in New Zealand: chest compressions
and rescue breaths.
Key messages
• CPR has become shorthand for resuscitation, with the terms used interchangeably. Resuscitation measures to preserve life and
organ function are far broader than CPR.
• Separation of CPR from other resuscitative measures will result in better clinician–patient conversations and more precise
treatment decisions tailored to preventing deterioration and, thus, cardiac arrest.
• In-hospital progressive deterioration leading to natural dying is different from sudden cardiac arrest.
An inverse coefficient problem for the fractional telegraph equation with the corresponding fractional derivative in time
Authors: Durdiev D. K. , Suyarov T. R. , Turdiev Kh. Kh.
Published: February 2025

This work investigates an initial-boundary value and an inverse coefficient problem of determining a time dependent coefficient in the fractional wave equation with the conformable fractional derivative and an integral. In the beginning, the initial boundary value problem (direct problem) is considered. By the Fourier method this problem is reduced to equivalent integral equations. Then, using the technique of estimating these functions and the generalized Gronwall inequality, we get apriori estimate for the solution via the unknown coefficient which will be used to study the inverse problem. The inverse problem is reduced to an equivalent integral equation of Volterra type. To show the existence and uniqueness of the solution to this equation, the Banach principle is applied. The local existence and uniqueness results are obtained.
Uniqueness of the solution to M.M. Lavrentiev’s equation with sources on a circle
Authors: Kokurin M. Yu.
Published: February 2025

A linear integral equation related to the coefficient inverse problem for a hyperbolic equation is considered. In the inverse problem, based on measurements of scalar wave fields scattered by an inhomogeneity, it is necessary to reconstruct the propagation velocity of the signal on the inhomogeneity. Probing fields are generated by point sources centered on a circle. We prove the unique solvability of the inverse problem with such an arrangement of sources under quite general assumptions on the choice of a variety of detectors. The relationship between the axial symmetry of the scattering data and the symmetry of the desired function relative to the same axis is established.
The ideal of identities of a variety generated by n-dimensional 2-algebras
Authors: Petrov E. P.
Published: February 2025

The problems related to the description of identities that hold in all n-dimensional associative nilpotent algebras over a field (n is fixed) are studied. The author previously formulated the hypothesis that an arbitrary n-dimensional nilpotent algebra over any field satisfies some standard identity of minimal degree, and a number of results were obtained in support of this hypothesis. In this article, it turns out that this hypothesis is also confirmed in the class of 2-algebras, that is, such locally nilpotent algebras over a field that the square of the principal ideal generated by any of the generators of the algebra is equal to zero. Moreover, the ideal of identities of a variety generated by n-dimensional 2-algebras over an arbitrary field (n is fixed) is described.

FROM LEGENDS TO A NEW REALITY. THE TRANSFORMATION OF SCANDINAVIAN MYTHOLOGY IN VIDEO GAMES
Authors:   Russian State University for the Humanities, Kosukhin Aleksandr V.
Published: February 2025

Among players, games that appeal to mythology, especially the
mythological system of the Scandinavian peoples, are extremely popular. This
makes it relevant to study the aspect of how mythology is integrated into the
gameplay and game narrative. In this work, we analyze the existence of Scandinavian mythology in computer video games as an element of their narrative.
The material for analysis was a wide range of visual and textual details, game
mechanics, gameplay details, and the game interface. Various ways of incorporating elements of Scandinavian mythology into video games were considered,
as well as their impact on the gameplay and player perception. Studying the
dynamics of the use of mythological systems by game developers allows us to
trace how the approach to the use of mythology in video games is changing
and how new interpretations and adaptations of mythological plots are created.
The results of the study can be useful for understanding how mythology affects
the creation and perception of video games, as well as for developing new gaming projects using mythological elements.
FAMILY PHOTO ALBUM AS A VISUAL NARRATIVE
Authors:   The State Order of Honor Maxim Gorky Museum, Demina Diana O.
Published: February 2025

Since the end of the 20th century, foreign and domestic researchers have paid serious attention to the study of family memory and methods of
its construction. One of the constructs that accumulates family memories is
considered to be a family photo album, which concentrates symbolic, figurative and verbal representations of the family past, which are reproduced, stored
and broadcast by members of the same family to ensure its integrity and unity,
the formation of individual and family identity, and also the transfer of significant value guidelines. Family artifacts such as albums and home photographs
are intended to convey an ideal image of the family and maintain family ties.
However, scientists focus particular attention not so much on the past event
itself, as on the problems of preserving and transmitting the memory of it. In
particular, researchers study the peculiarities of the construction of reality by
members of a certain society from the position of narrative analysis. The purpose of the paper under consideration is to present a family photo album as an
integral, visual narrative about the family’s past, identifying the key aspects of
this method of forming family memory. Therefore, the article compares home
photography and family photo album as different forms of visual narrative in
terms of strategies of narrative text organization, its structure and the specifics
of its creation.

Published: February 2025

One of the six Landrace piglets was born without skin on their thighs. Physical examination showed that the piglets had a birth weight of 1.32 kg, temperature of 39.1oC, absence of skin on the back of the right (4.2 × 7.1 cm) and left (5.1 × 5.3 cm) thighs and the base of the tail, and open wounds. Based on signalment, case history, and physical examination, the piglets were diagnosed with epitheliogenesis imperfecta (EI). The therapy administered was procaine antibiotics and benzathine penicillin G at a dose of 1 ml/10 kg body weight (BW) once injection. Diphenhydramine HCl at a dose of 1 mg/kg BW was given once. Wound cleansing was performed daily with 0.9% NaCl infusion solution, and a 10% povidone-iodine antiseptic was administered for 14 days. The wound was left open without dressing. On the 3rd day after birth, piglets were supplemented with Ferdex® Plus at 2 ml/piglet once. Piglets were left with their sows during the treatment. Treatment results showed healing starting from the formation of a scab on day three and slowly sloughing off until day 8 (remaining ± 10% of the scab). The skin had fully grown, and the wound had completely healed by day 15 after the piglets were born.

Authors: Devira Dinda , Gorda I Wayan , Sudisma I Gusti Ngurah
Published: February 2025

Prolapsed nictitating membrane gland, or "cherry eye," is a common ocular condition in dogs, characterized by protrusion of the third eyelid gland due to weakened connective tissue, often causing inflammation and infection. A 1-year-old, 11 kg male Kintamani dog presented with a persistent reddish mass protruding from the corner of the right eye for three months. Clinical examination, history, and physical findings confirmed nictitating membrane prolapse (cherry eye), with a favorable prognosis. Cherry eye occurs when the gland of the third eyelid prolapses from its normal position, forming a swollen red mass at the medial canthus. Surgical correction was performed using the Morgan's pocket technique. The dog was premedicated with atropine sulfate, and anesthesia was induced using xylazine and ketamine. The prolapsed gland was repositioned between the two incision lines with gentle downward pressure and then sutured using 4-0 PGA (Assucryl®) in a simple continuous pattern. Postoperative care included antibiotic and anti-inflammatory eye drops (Cendo Xitrol®: Neomycin Sulfate, Polymyxin B Sulfate, Dexamethasone) and oral meloxicam for analgesia. By day 13 post-surgery, the eye had fully recovered, with no signs of recurrence or complications.

Authors: Saltarelli Maurizio , Pantalone Marco
Published: February 2025

The present study shows the results of the long-term monitoring of the Peregrine Falcon Falco peregrinus nesting in the Furlo Gorge State Nature Reserve located in the Marches region (central Italy). Monitoring took place between 1997-2022, when a minimum of 1 and a maximum of 3 breeding pairs nested within the protected area. During the study period, we identified 11 nesting sites used by the Peregrine Falcons that were located on cliffs with ledges and small niches, placed at an average height of 416 m (±89 m) a.s.l. Over the study period, the breeding pairs laid a total of 69 eggs, with an annual mean of 2.34 per pair, raising a total of 61 chicks of which 57 fledged successfully. Breeding attempts always occurred in March (with a pronounced peak in the second week) and incubation period lasted on average 32±1.60 days. During the 23 years of monitoring, the productivity rate was of 1.32 (n fledglings/n pairs), with a chick mortality of only 2.44% and a fledging success of 2.47 (fledglings/pairs with juveniles). This study highlights the Furlo Gorge as the second most important monitored breeding area for the Peregrine Falcon in the Marches region being the first one the Regional Park Gola della Rossa e di Frasassi (AN).

Authors: Wang Jiaojiao
Published: February 2025

The Belt and Road Initiative has catalyzed the globalization of Chinese infrastructure enterprises, creating an urgent demand for civil engineering professionals equipped with both technical expertise and cross-cultural adaptability. Higher vocational colleges in China have adopted the Industry Education Integrated Model to bridge the gapbetween academic training and industry needs. However, persistent discrepancies between graduate preparednessand overseas workplace requirements underscore systemic challenges in curriculum design, stakeholder collaboration, and competency assessment. This article expands upon existing research by introducing the School-Enterprise-Employee model, a tripartite framework that evaluates competency alignment across stakeholders. Through a case study of BRI projects in Malaysia, the study highlights the critical role of transnational competency development in vocational education. Empirical data from pilot programs reveal a 15% increase in graduate retention and a 22% reduction in compliance violations, validating the SEE model’s efficacy. The article concludes with actionable policy recommendations to enhance the global readiness of civil engineering graduates.

Creating inclusive AI and Blockchain Curricula in Developing Countries: Frameworks, Strategies and Implementation
Authors: Ayomide Arowolo-Ayodeji  , Osazuwa Efe Ernest
Published: February 2025

The research analyzed educational initiatives around AI and blockchain technologies in developing nations. The researcher initiated this investigation because developing countries face ongoing technological adoption barriers for advancing education with AI and blockchain solutions. A detailed interview session with 25 stakeholders representing multiple geographical areas and professional fields allowed researchers to examine modern technological learning practices while revealing crucial barriers like inadequate infrastructure and cultural traditions yet financial constraints preventing substantial education and skill development. The research project incorporated a qualitative methodological framework through virtual semi-structured interviews that served as its primary data collection instrument. As a part of the research method the study used a qualitative approach supported by virtual semi-structured interviews for gathering first-hand data. Virtual semi-structured interviews were chosen as the main data collection method to obtain detailed understandings about AI and blockchain education in developing countries and to generate solutions fitting economic and cultural characteristics. Research findings indicate that developing countries need more than technological transfer to succeed in effective technological education because they require culturally-aware holistic approaches that both validate local settings and deliver globally apt skill development programs. Research results also showed the need for multi-sector partnerships between public entities and educational facilities and technology firms and community support groups to build lasting educational structures which exceed singular organization capabilities. The study identifies strong evidence that suggests AI and blockchain education will act as the base for societal economic development over an extended period. This newly proposed framework represents a transformational system for technological education which strategically dismantles obstacles while establishing comprehensive access pathways for students to engage deeply with advanced technology concepts.

Published: February 2025

In this present study, electronic, mechanical, thermodynamic and optical properties of RaHfO₃ crystal were investigated by Generalized Gradient Approximation (GGA) based on PBE, RPBE, and PBEsol and hybrid B3LYP methods. The calculated bandgap energies (Eg​) of RaHfO₃ were found to be 2.247 eV, 2.178 eV, 2.095 eV, and 3.520 eV, as determined using the PBE, RPBE, PBEsol, and B3LYP approaches, respectively. The atomic orbital properties of Ra, Hf, and O in RaHfO3 were analyzed through total and partial density of states (DOS) analysis. Mulliken population charge analysis provided insights into the bonding characteristics of the RaHfO3 crystal. Mechanical stability was verified using the Born stability criterion, and Poisson’s ratio and Pugh’s ratio were evaluated to assess ductile strength and elastic anisotropy. To find out the material's thermodynamic stability and state behavior, thermophysical factors were seized at. The RaHfO3 crystal demonstrates both mechanical and thermal stability, along with ductile behavior and elastic anisotropy. Its optical properties were thoroughly evaluated focusing on energy and wavelength, both approaches confirmed that RaHfO3 exhibits remarkable absorption in the visible and ultraviolet regions. These outstanding properties suggest that RaHfO3 could be a promising candidate for photocatalytic applications, demonstrating efficient responsiveness to visible light.

Authors: Yijie Weng  , Jianhao Wu
Published: February 2025

The rapid evolution of artificial intelligence (AI) has amplified the need for efficient database management systems (DBMS) to handle the growing volume, variety, and velocity of data. PostgreSQL, a robust relational database, and MongoDB, a leading NoSQL solution, are two widely adopted DBMSs in AI applications, each offering unique advantages. This paper provides a comprehensive comparative analysis of PostgreSQL and MongoDB, focusing on their suitability for AI use cases. Key evaluation criteria include data modeling, query complexity, scalability, ACID compliance, indexing, and integration with AI frameworks. PostgreSQL excels in scenarios requiring strict data consistency, complex querying, and structured data, making it ideal for financial modeling, scientific research, and feature engineering. Conversely, MongoDB's schema-less design, horizontal scalability, and native support for semi-structured data align with real-time analytics, IoT, and evolving AI datasets. The study highlights that the choice between the two databases depends on specific project requirements and proposes hybrid approaches to leverage their complementary strengths. This analysis aims to guide AI practitioners in making informed database decisions to optimize performance, scalability, and flexibility in AI systems.

Acute kidney injury (AKI) due to perioperative rhabdomyolysis is a rare but severe complication that can occur during prolonged surgical procedures, especially in patients with predisposing factors such as obesity, diabetes, and metabolic disorders. This case report describes a 40-year-old woman with a history of non-insulin-dependent diabetes and obesity, who developed AKI following a 10-hour meningioma surgery. During the operation, she received low-dose anesthetic agents, including propofol and rocuronium. Postoperatively, she developed oliguric acute kidney injury, accompanied by hyperkalemia and elevated creatine phosphokinase (CPK) and myoglobin levels, confirming rhabdomyolysis. The patient was managed with daily dialysis, resulting in gradual urine clearance, improved renal function, and resolution of muscle damage markers. This case highlights the importance of early diagnosis, prevention, and management of rhabdomyolysis in the perioperative setting, particularly in high-risk patients, to prevent severe complications like AKI.

Authors: Gajjala Manasa Reddy  , Narayan M  , Ramnath Koti
Published: February 2025

The occurrence of foreign body (FB) penetration into the orbit is a relatively uncommon type of injury. FBs can be classified as either organic or inorganic, and they may remain asymptomatic within the orbit or result in significant complications such as cellulitis, optic neuropathy, and ocular dismotility. Asymptomatic inorganic FBs can often be monitored without the necessity for surgical intervention. When contemplating surgical removal, it is essential to consider the potential complications associated with the procedure, as well as the composition of the FB and its possible effects on the intraorbital environment. This report reviews the clinical characteristics and management outcomes of a cohort of patients who underwent orbitotomy for the removal of FBs.Intraorbital foreign bodies are primarily composed of inorganic and metallic materials, with a notably higher prevalence among young males. Although orbital cellulitis is generally linked to organic foreign bodies, it may also occur due to metallic items that breach the lacrimal sac or paranasal sinuses. By employing suitable precautions, the extraction of intraorbital foreign bodies can be performed effectively and safely through contemporary orbitotomy methods

Kelangkaan Pada Komplikasi Multisistem Kehamilan : Studi Case Report pada PPCM, SN, dan RHD
Authors: Basoeki Rijanto Agoeng , Akbar Mochammad Afif Amrullah
Published: February 2025

Kehamilan dapat memicu komplikasi kardiovaskular dan ginjal, seperti peripartum
cardiomyopathy (PPCM), sindrom nefrotik (SN), dan penyakit jantung rematik
(RHD), yang meningkatkan risiko bagi ibu dan janin. PPCM terjadi akibat gagal
jantung di akhir kehamilan atau pasca persalinan, sedangkan SN ditandai dengan
proteinuria dan edema. RHD dapat memperparah kondisi ini, terutama dengan
adanya stenosis mitral. Laporan kasus ini bertujuan untuk menggambarkan
gambaran klinis serta managemen komplikasi pada kehamilan. Seorang wanita
berusia 37 tahun, G2P1, usia kehamilan 33 minggu datang dengan keluhan perut
kencang dan sesak nafas. Keluhan disertai demam, lemas, dan bengkak pada tungkai
bawah. Pemeriksaan didapatkan tekanan darah tinggi, proteinuria serta ditemukan
pembesaran jantung dan mitral stenosis dari hasil ekokardiografi. Pemeriksaan
obstetri ditemukan bayi dengan DJJ 117 bpm dan kepala belum memasuki pintu atas
panggul. Penanganan kehamilan dengan komplikasi seperti peripartum
cardiomyopathy (PPCM), sindrom nefrotik (SN), dan penyakit jantung rematik
(RHD) memerlukan pendekatan multidisiplin yang ketat. Pemantauan fungsi
kardiovaskular dan ginjal sangat penting untuk mencegah komplikasi lebih lanjut.

Miopia Tinggi pada Kehamilan : Case Report
Authors: Basoeki Rijanto Agoeng , Ramadhani Devi Eka , Tarina Nadia , Aisyah Nabilla Nur
Published: February 2025

Background: High Myopia (HM), defined as a myopic refractive error of ≥6 diopters
(D) or an axial length (AL) greater than 26.5 mm, is associated with various typical
pathological changes, such as fundus tessellation, conus, macular lesions, as well as
peripheral retinal and choroidal lesions. The choroid and retina are thought to be
vulnerable to the effects of pregnancy. HM is associated with retinal changes, and
patients with HM have a high risk of experiencing retinal detachment. Objective : This
case report aims to describe high myopia in pregnancy. Case Presentation : A 23-year-
old woman, GIP00000, at 37 weeks of gestation, came to the emergency department of
Dr. Soegiri Lamongan General Hospital with complaints of intense abdominal tightness
and swollen, painful feet. Her vision appeared blurred. High blood pressure was noted
in the third trimester. An obstetric examination showed that the fetal head had not
entered the pelvic inlet. Clinical symptoms included blurred vision, with visual acuity
results of VOD -8.00 D and VOS -8.00 D. Conclusion : High myopia in pregnancy is
a rare case. Diagnosis is based on patient history, clinical symptoms, and supportive
examinations. High myopia is not a contraindication for normal delivery. However,
high myopia poses a significant risk during pregnancy, which was considered as a basis
for a cesarean section to reduce risks in our case.

A Deep Reinforcement Learning-Based Technique for Enhancing Cache Hit Rate by Adapting to Dynamic File Request Patterns
Authors:   Korean Institute of Smart Media, Kwon Mingoo , Song Minseok
Published: February 2025

Improving the cache hit ratio in edge caching is crucial for effectively handling file requests within limited cache capacity and optimizing network and system resources. This study proposes a file cache management approach based on Deep Reinforcement Learning (DRL). The proposed method aims to enhance data access performance by efficiently utilizing limited cache resources, adapting to dynamic file request patterns, and improving the cache hit ratio. Specifically, it employs the Proximal Policy Optimization (PPO) algorithm to intelligently manage cache replacement policies and effectively handle the complexity of continuous action spaces. The PPO network consists of an action space for caching decisions, an observation space reflecting changes in file access patterns, and a reward model evaluating the costs and benefits of various caching strategies. Experimental results demonstrate that the proposed method improves the cache hit ratio by an average of 2.28% and up to 16.25% compared to traditional greedy algorithms, validating the effectiveness of the DRL-based approach in constrained cache environments.

The current mathematics learning process is often conducted in a blended manner, combining offline and online learning. Therefore, online learning requires instructional media that support the learning process and are appealing to students. However, the instructional media currently used to support online learning are limited and less relevant. This study aims to develop interactive mathematics learning media in the form of ethnomathematics-based e-comics that are valid, practical, and effective for middle school students. The research method employed is development research using the ADDIE model. The research subjects included middle school teachers and students. In the limited trial phase, 2 teacher and 32 students participated, while the large-scale trial involved 3 teachers and 57 students. Data collection instruments consisted of validation sheets for material and media experts, student response questionnaires, as well as pre-test and post-test questions validated by experts. Data analysis was conducted descriptively to assess the feasibility of the product. The research findings indicate that the ethnomathematics-based e-comic learning media are valid and practical. Furthermore, the e-comics meet the effectiveness criteria, as they enhance students' numeracy skills after the learning process. Therefore, the e-comics developed in this study can serve as a reference for mathematics learning media that meet current student needs.
Mathematical analysis of ROC-TOPSIS method for prioritizing road repair decisions
Authors: Sur Widiya Astuti Alam , Machfiroh Ines Saraswati
Published: February 2025

Determining the priority of road damage in road construction typically relies on assessments based on the Pavement Condition Index (PCI) method. However, the PCI classification does not provide specific criteria to distinguish between road sections within the same classification, complicating the identification of sections in worse condition. To address this issue, mathematical analysis can employ multi-criteria decision-making (MCDM) methods to prioritize road sections for repair. One effective approach is the integration of the Rank Order Centroid (ROC) and Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) methods. The analysis results indicate that the road sections prioritized for repair were located at Location III: Alternative 70, Alternative 80, and Alternative 42. Based on the Pearson correlation coefficient between the ranking orders of the pavement assessment using PCI and ROC-TOPSIS, there is a 65% similarity. Consequently, ROC-TOPSIS can serve as an alternative method for determining priority repairs, as it aligns with the results of the road pavement assessment.
