Authors: Br Sitepu Rasita Natasya , Cahyadi Putra I Gusti Ngurah Anom
Published: February 2025

Distributor merupakan suatu kelompok usaha yang melakukan distribusi penyaluran produk ke suatu tempat ke tempat lain. Saluran distribusi sangat dipengaruhi faktor jalur pengiriman barang yang efisien sehingga bisa menghemat waktu dan biaya. Namun tidak jarang distributor mengalami kendala saat melakukan pengantaran barang, seperti waktu perjalanan yang terlalu lama dan bingung memilih tujuan mana yang terlebih dahulu dikunjungi. Salah satu penyebabnya karena luasnya wilayah yang harus ditempuh. Penyebab lainnya disebabkan karena banyaknya jalan raya terlebih lagi volume kendaraan yang banyak sering kali menyulitkan seseorang untuk mencari jalur terpendek ke tempat tujuan yang terdekat, baik dari segi jarak maupun waktu tempuh. Dari ranah bidang ilmu Informatika, penentuan rute distributor ini termasuk ke dalam permasalahan Travelling Salesman Problem. Permasalahan TSP dapat diselesaikan menggunakan beberapa algoritma, salah satunya adalah algoritma A Star. Algoritma A Star adalah salah satu algoritma pencarian graf dengan menggunakan fungsi jarak-plus-biaya untuk menentukan urutan titik yang akan dikunjungi. Dalam permasalahan ini yang harus dipecahkan adalah bagaimana cara agar bisa mengunjungi tempat yang dituju dengan jarak, waktu dan biaya yang minimum. Pada penelitian ini menggunakan data primer berupa 17 titik toko yang sudah ditentukan di wilayah kota Denpasar berupa lokasi sebagai vertex dan jarak antar toko.

Patriotism in the context of the formation of social competence of the younger generation (using the example of the activities of the supplementary education system)
Authors: Moroz Egor  Vladimirovich , Pervova Irina  Leonidovna
Published: February 2025

The process of forming civic guidelines for the social competence of the younger generation is analyzed using the example of the activities of the additional education system in St. Petersburg. The practices of forming civic guidelines for the social competence of the younger generation were chosen as the object of this study. The article presents the materials of a study conducted on the basis of the city Center for Patriotic Education and Preventive Work in 2022, during which the practices of civic and patriotic education of students of educational organizations in St. Petersburg were studied in detail. Two components of the process of forming the social competence of the younger generation were identified: the construction of the semantic content of the value of patriotism (the formulations used to describe this value in the documents studied), as well as the forms of representation of this value directly during the educational process (the forms and types of activities in which students are directly involved). In addition, the frequency of mentions of certain semantic categories in the general discourse space of the Center's activities was recorded. The main methods of scientific research are the method of document analysis and the method of semi-structured interviews. To interpret the results, the authors based the research on the theory of social constructionism and the theory of discourse analysis by E. Laclo and S.Mouff. The authors conclude that today the patriotism is the most important civic quality for the formation of social ties in modern Russia. In some cases its significance is so great that it completely replaces the semantic content of the concept of "citizenship". At the same time, there is a tendency to militarize the concept of patriotism both at the level of constructing its semantic content and in the course of representation practices, presented mainly through semantic categories and activities inextricably linked to military subjects. The authors record the discrepancy between the understanding of the semantic content of civic values by modern adolescents and the older generation. This situation suggests that the existing practices of representing patriotism are not fully consistent with the ideological demands of both the state and the younger generation, which indicates the need to search for new images of civic values.
El mercado de rentas decimales y sus agentes. Arrendar el diezmo del vino en el arzobispado de Sevilla a finales del siglo xv
Authors:   Universidad de Málaga (España), Requena Parra Andrés
Published: February 2025

This study analyzes the tithing rents market and its agents in the last years of the 15th century. To do this, the fiscal map of the archbishopric of Seville is addressed, the profile of the agents involved in the leasing of the tithe and the way in which they participated in the system. At the same time, the economic characteristics of the period and the relationship they have with the tithe rent are considered. For this purpose, the data contained in the so-called «libros de las rentas de los diezmos del vino y del aceite» preserved in the Archivo Catedral de Sevilla will be used, as these are suitable for our objective, as well as because they are the only complete lists of lessees for the medieval period. All of this has allowed us to verify the local and «minimalist» profile of the agents involved in the tithe, the atomization of the tithing rents market and the relationship between this tax and the dense web of small economic transactions that interweaved and supplied the medieval markets.
Recaudar los tributos en tiempos de peste: impacto de las epidemias en las economías urbanas y la fiscalidad sobre el consumo en Castilla (1467-1508)
Authors:   Universidad de Málaga (España), Ortego Rico Pablo
Published: February 2025

The aim of this paper is to offer a general approach, based on significant examples, to the circumstances under which the public powers and local agents of the Crown of Castile managed the collection of royal and urban taxes on consumption and commerce in epidemic contexts, for a chronology that extends between 1467 and the great plague epidemic of 1507-1508. The following aspects will be addressed: the chronology and extension of the plague cycles of the period; the economic disruption factors caused by epidemics, or by the measures adopted to contain their spread; its consequences on trade and consumption taxes; the mechanisms articulated by public powers and tax collectors to mitigate or repair economic damage, based on forms of negotiation aimed at facilitating or making payments more flexible. With this, it will be possible to observe to what extent the public powers and tax collectors reacted to those adverse situations, proposing solutions to compensate for the problems caused by the plague and limit its effects on the «financial fabric»
La percepción del espacio geográfico en la Inglaterra altomedieval: paisajes imaginarios y domésticos en el manuscrito Cotton Tiberius B.v/1
Authors:   Universidad de Murcia (España), Conde-Silvestre Juan Camilo
Published: February 2025

In this paper I intend to shed light on how geographical space was perceived and arranged in Anglo-Saxon England, particularly in the eleventh century, through a couple of key texts from MS Cotton Tiberius B.v/1 at the British Library in London. The manuscript is a miscellany with two documents of geographical interest: versions in Latin and Old English of The Wonders of the East (ff. 78v-97v) and a mappa mundi (f. 56v). From the first text we learn how remote lands were perceived, mainly by means of the creatures that inhabited them: marvellous (mirabilia) and legendary beings. The Wonders of the East also makes reference to specific placenames, many of them made up, and focuses on luxurious descriptions of buildings and natural features. In contrast, the mappa mundi focuses on the known world (oecumene), whose rivers, seas, mountains and main towns are systematically labelled. In this way, the Cotton map yields a first-hand knowledge of geographical space in eleventh century England. In this context, the relevance of northern Germania, Scandinavia and, especially, Great Britain and Ireland must be highlighted.

Association between maternal anemia and low birth weight among stunting children 12−23 months in Dili, Timor Leste
Authors: Florencia Grifit Joiner Da Costa Hornay , Chandra Dian Novita , Lestari Wiji
Published: February 2025

Background: Stunting is a chronic malnutrition problem primarily occurring during the first 1000 days of life. Iron deficiency anemia during pregnancy can threaten fetal growth and may affect the baby's birth weight and length. According to the Timor-Leste Food and Nutrition Survey 2020, stunting in Timor-Leste is 47.1%.
Objectives: To determine the relationship between a history of anemia during the third trimester of pregnancy and low birth weight with the incidence of stunting in children aged 12-23 months in Dili city.
Methods: This study was a case-control design conducted in five health centers in Dili City, Timor-Leste. The sample consists of 180 children aged 12-23 months, with 90 stunted cases and 90 controls selected consecutively. Data collected encompasses both child-related and maternal information.
Results: Anemia during the third trimester of pregnancy OR 95%CI 7.18 (3.38-15.23) and low birth weight OR 95%CI 5.39 (2.09 – 13.90) are significantly associated with the incidence of stunting (p < 0.01).  Based on logistic regression analysis, anemia during pregnancy and low birth weight are not significantly associated with an increased risk of stunting. However, there are characteristics of the mother and child that are significantly associated with the risk of stunting.
Conclusion: Children with a history of low birth weight are 5.3 times more likely to experience stunting, and children whose mothers had anemia during pregnancy are 7.2 times more likely to experience stunting. The results show that low birth weight and maternal anemia are related to the incidence of stunting in Timor-Leste.

Authors: İpek Bahar , Taştan Zarife
Published: February 2025

The aim of this study is to examine the effect of educational games on peer bullying and emotion in physical education and game lessons. The study group consisted of 19 4th-grade primary school students (9 girls and 10 boys) from the 2023-2024 academic year, selected through criterion sampling. A game-based activity was implemented in physical education and game lessons for eight weeks. The Games and Emotions Scale for Children and the Peer Bullying Scale were used for data collection. The study followed a within-group experimental design, with pretest, posttest, and follow-up measurements. In data analysis, one-way ANOVA for repeated measures, one-way ANOVA for independent samples, and independent samples t-test were applied. The findings revealed that playing games in physical education and game lessons reduced peer bullying among children but did not have a significant impact on their emotional states. This effect was sustained in the retention measurements. Furthermore, no significant differences were found in peer bullying and emotional states based on gender and participation in sports courses outside school. Except for the bully sub-scale, no significant difference was observed in peer bullying concerning time spent on the internet. As a result, the study highlights the importance of educational games in reducing and preventing peer bullying. Additionally, integrating traditional games into the curriculum may help decrease peer bullying while improving students' social skills and empathy levels.

Machine learning surrogate models for mechanistic kinetics: Embedding atom balance AND positivity
Authors: Kircher Tim , Votsmeier Martin
Published: February 2025

Multiscale simulations of reactive flows are critical in many fields. However, their application is often hindered by the high computational cost of solving detailed chemical kinetics. Recent advances in surrogate models for reactive chemistry offer promising speedups, but ensuring that these models remain physically consistent remains challenging. In particular, machine learning models for chemical kinetics must enforce atom balance and guarantee the positivity of predicted concentrations. Here, we introduce a positivity preserving projection that simultaneously enforces both constraints. We demonstrate this approach using an example from atmospheric chemistry and an example from heterogeneous catalysis. In both cases, the positivity preserving projection yields exclusively positive model predictions conforming to the atom balance, without reducing the overall accuracy of the model.
An Accurate, Affordable Density Functional Tight-Binding Model for Excited State Hydrocarbon Polymer Molecular Dynamics
Authors: Stroscio Gautam , Pham Cong Huy , Niehaus Thomas , Goldman Nir
Published: February 2025

We have developed a density functional tight-binding model for hydrocarbon excited state dynamics by referencing to high-level electronic structure theory and incorporating a many-body repulsive energy. We then validate our model against n-octane geometry optimizations, bond dissociation scans, and vibrational frequencies. Our model is approximately 1000 times more efficient than hybrid time-dependent density functional theory calculations with comparable accuracy. Our efforts enable longer timescale excited state simulations of photochemistry and scattering of incident radiation.
Light-Driven Constitutional Pump Powers Far-From-Equilibrium Dynamic-Covalent Behavior

Published: February 2025

Accessing non-equilibrium states in dynamic covalent chemistry (DCC) remains fundamentally challenged by microscopic reversibility and rapid equilibration. Drawing inspiration by the kinetic asymmetry mechanisms prevalent in living organisms, we introduce a light-driven constitutional pump that establishes a unidirectional kinetic pathway beyond intrinsic equilibria, that autonomously driving a dynamic covalent C=C/C=N metathesis reaction far from equilibrium. This pump operates through a kinetic ratchet mechanism under single-wavelength photonic control: (1) photocyclization of a diarylethene-based Knoevenagel derivative generates a high-energy photoisomer (ΔG = 22.5 kcal/mol), (2) irreversible covalent metathesis (K > 10^16) releases stored chemical potential, and (3) a photon-energy-gated ring-opening reaction enforces pathway unidirectionality. The resulting strong directional bias drives the system to a non-equilibrium steady state (NESS), achieving a 28-fold amplification of the equilibrium constant while preserving closed-system reversibility. Integrated into polymer networks, this pump enables spatiotemporal control over crosslink density, producing photo-adaptamers with non-equilibrium modulus switching. Unlike catalytic approaches, this platform achieves kinetic control by elevating the energy of intermediates through photonic programming, establishing DCC as a versatile toolbox for designing life-inspired adaptive materials.

Dermatomyositis (DM) is a rare idiopathic inflammatory myopathy
characterized by skin, muscle and various systemic involvement, with cardiac
manifestations serving as critical prognostic factors. The management of
cardiac involvement in DM remains challenging and subject to ongoing
debate. We present a 72-year-old female with DM complicated by cardiac
involvement, refractory to corticosteroids and mycophenolate mofetil.
Treatment with a novel intravenous immunoglobulin preparation led to
a marked reduction in cardiac enzyme levels, as well as improvements in
strength, dyspnea, and dysphagia. This IVIg preparation differs regarding
manufacturing process and shows a favorable safety profile. This case
highlights the potential of IVIg in managing cardiac involvement in DM.

Published: February 2025

Fusarium is a genus of filamentous fungi that can cause disseminated
infections. Fusariosis is the second most common invasive fungal infection
in patients with hematological malignancies. Disseminated infections
occur specifically in patients with profound neutropenia. Fusarium
infections are suspected in those who have had a prolonged fever; other
clinical forms include cutaneous, sinusitis, pneumonia, endophtalmitis,
and fungemia. Cutaneous fusariosis in immunocompromised patients
presents in a disseminated form. The most common lesion in patients
with cutaneous involvement are erythematous and painful nodules or
papules, with or without central necrosis. In the work, we report a case of
cutaneous fusariosis in a pediatric patient, which is rare, with condition
that leads to immunosuppression. The presentation was solely cutaneous,
which is the least common presentation. It is necessary to determine if
there is involvement of different organs. Prolonged treatment is required.
More large-scale clinical studies are needed to characterize the optimal
antifungal regimen and treatment duration.

Background and Objectives: Due to the wide spectrum of risk for death and recurrent events among patients with Non-ST Elevation Myocardial Infarction (NSTEMI), management guidelines emphasize the importance of early risk stratification. In addition to prognostic assessment, predicting the anatomical extension of coronary artery disease (CAD) is potentially useful for clinical decisions. The aim of the study was to determine whether the CHA2DS2-VASc-HSF score correlates with the angiographic extent and severity of CAD in patients with NSTEMI.

Methods: It was a cross-sectional observational study. A total of 80 patients with NSTEMI were enrolled. Based on the CHA2DS2-VASc- HSF score, the patients were divided into low (≤4) and high (>4) risk groups. All patients underwent coronary angiography during the index hospitalization and the severity of CAD was assessed by the SYNTAX score. The association between the CHA2DS2-VASc-HSF score and the SYNTAX score was evaluated.

Results: The mean age of patients was 50.58±9.53 and 54.48±10.66 years for group I and group II respectively with the majority (81.2%) being male. The mean CHA2DS2-VASc-HSF score of the patients was 2.68±0.92 in group I and 5.48±0.60 in group II (P value=<0.001). The median SYNTAX score was 7.50 (range 0.0 to 24.0) in Group I and 23.3 (range 0.0 to 39.0) in Group II (P value=<0.001). The CHA2DS2-VASc- HSF score was positively and significantly correlated with the SYNTAX score (Spearman’s ρ =0.703, p<0.001). A CHA2DS2-VASc-HSF score of 4.5 has 86.7% sensitivity and 72.0% specificity to detect severe coronary artery involvement (SYNTAX score >22).

Conclusion: The study demonstrated that the CHA2DS2-VASc-HSF score was associated with the severity of coronary artery disease in patients with NSTEMI. Notably, those with elevated CHA2DS2-VASc-HSF scores tended to have higher SYNTAX scores.

Kualitas butir soal pada kompetisi matematika merupakan faktor yang wajib terpenuhi agar mampu menyeleksi peserta dengan kemampuan terbaik. Adakalanya peserta yang lolos pada babak penyisihan memanfaatkan kelemahan butir soal. Namun demikian, pendekatan klasik tidak mampu menganalisis kelemahan butir soal sehingga diperlukan pendekatan teori respon item untuk memperoleh gambaran kemampuan peserta. Penelitian ini bertujuan menganalisis kualitas butir soal yang digunakan pada babak penyisihan competition of mathematics (Comath) Universitas Musamus tahun 2023 menggunakan teori respon item. Terdapat 25 butir soal pilihan ganda dengan jumlah peserta sebanyak 24 tim. Teknik analisis menggunakan pendekatan respon item model rasch dengan bantuan software Ministep. Hasil penelitian menunjukkan skor reliabilitas butir item dan peserta pada kategori baik dengan koefisien alpha cronbach sebesar 0,91. Rata-rata kemampuan peserta berada di bawah item dengan -0,35 logit. Nilai Outfit MNSQ dan Outfit ZSTD berada pada kategori fit yang berarti bahwa  seluruh item mampu mendeksripsikan kemampuan peserta secara rasional. Instrumen soal yang digunakan fit (cocok) dengan Model Rasch dalam menyeleksi kemampuan peserta dengan baik.
