Published: July 2023

Ruas Jalan Soekarno Hatta merupakan jalan kolektor sekunder 4 lajur 2 arah terbagi (4/2 D) sebagai jalan utama menuju pusat perdagangan Kota Bukittinggi. Berdasarkan observasi awal yang dilakukan terlihat bahwa, kendaraan yang melalui ruas jalan ini cukup ramai, bahkan sering terjadi kemacetan yang disebabkan oleh area wilayah tersebut merupakan area pasar dan pusat pertokoan yang tidak memiliki lahan parkir yang cukup sehingga aktivitas parkir banyak menggunakan sebagian badan jalan yang menyebabkan terjadi penyempitan lebar jalan efektif. Adapun tujuan penelitian ini untuk mengetahui dan menganalisis kinerja ruas Jalan Soekarno Hatta yang ditinjau dari volume lalu lintas, kapasitas, dan tingkat pelayanan (LOS). Sedangkan metode yang digunakan yaitu metode MKJI 1997 dengan mengumpulkan data primer, berupa data geometrik jalan, volume lalu lintas dan hambatan samping yang diperoleh langsung di lokasi penelitian, dan data sekunder, berupa data jumlah penduduk. Berdasarkan hasil penelitian diperoleh volume lalu lintas maksimum terjadi pada survei utama yaitu pada hari rabu untuk kedua arah sebesar 518,25 smp/jam dan 522,25 smp/jam pada pukul 11.30 sampai 12.30 WIB dan 11.00 sampai 12.00 WIB. Sedangkan untuk kapasitas diperoleh samasama sebesar 1148,82 smp/jam untuk kedua arah. Kemudian juga rata rata kecepatan tertinggi pada ruas jalan soekarno hatta yaitu sepeda motor dengan kecepatan 20,08 Km/jam arah Janjang 40- Bypass dan arah sebalik nya dari Bypass-janjang 40 kecepatan tertinggi juga sepeda motor dengan kecepatan 20,20 Km/jam. Hambatan samping pada ruas Jalan Soekarno Hatta termasuk dalam kategori kelas hambatan samping sangat tinggi (VH). Dan ditinjau dari tingkat pelayanan ruas Jalan Soekarno Hatta termasuk kategori C dimana untuk klasifikasi jalan arus terbilang lancar, kecepatan masih dikendalikan, V/C masih dapat ditolerir. Rekomendasi yang disarankan yaitu dengan di lakukannya penertiban lahan parkir untuk pengendara sepeda motor dan disediakannya tempat khusus untuk mobil angkutan kota (angkot) untuk menunggu penumpang serta pemasangan rambu-rambu dilarang berhenti dan rambu-rambu dilarang parkir.

Published: July 2023

Maraknya praktik judicial corruption yang diawali dengan pelanggaran kode etik Hakim, menuntut lembaga Komisi Yudisial untuk bertindak lebih tegas dalam mengawasi perilaku Hakim. Guna meminimalisir aksi “Hakim nakal” tersebut, KY memiliki pasal mengenai kewenangan penyadapan. Namun statusnya yang merupakan lembaga non-penyidik dan hanya berfungsi mengawasi kode etik hakim, membuat beberapa pihak tidak menyetujui keberadaan pasal penyadapan itu. Berdasarkan permasalahan tersebut, penulis bermaksud untuk mengkaji penerapan wewenang penyadapan oleh KY dalam proses pengawasan dan penegakan kode etik Hakim dengan ditinjau melalui salah satu konsep kaidah fiqhiyyah yaitu, kaidah al-ḍararu yuzālu biqodri al-imkān. Metode penelitian dalam tulisan ini bersifat penelitian pustaka (library research). Pendekatan penelitian menggunakan pendekatan perundang-undangan dan pendekatan konseptual. Teknik pengumpulan data didapat melalui analisis buku-buku, jurnal, maupun literatur lainnya. Data yang berhasil dikumpulkan kemudian diolah menggunakan analisis kualitatif deskriptif, dimana hasil penelitian dituangkan secara deskriptif bukan dengan hitungan angka. Hasil penelitian ini menunjukan bahwa dalam tinjauan konsep al-ḍararu yuzālu biqodri al-imkān, menerapkan wewenang penyadapan oleh KY sangat dibutuhkan dalam proses pengawasan dan penegakan kode etik hakim guna mencegah kejahatan Hakim yang berpotensi menimbulkan kerugian lebih besar bagi masyarakat.

Published: July 2023

Pernikahan merupakan suatu permasalahan yang diatur secara rinci dalam hukum Islam, dikarenakan hal tersebut termasuk kedalam kategori yang sacral untuk dilaksanakan. Ada beberapa macam pernikahan yang salah satunya dinamakan dengan istilah nikah mut’ah atau dikenal dengan nikah kontrak. Secara huku Islam pada awal penyebarannya nikah mut’ah masih diperbolehkan karena beberapa faktor, namun demikian hukum tersebut sudah dihapus dan diharamkannya nikah mut’ah. Akan tetapi dalam masyarakat khususnya Indonesia praktik nikah mut’ah masih sering terjadi. Pada penelitian kali ini menggunakan metode penelitian kualitatif, yang mana pendekatan dalam metode ini dilakukan yaitu bahan pustaka dikaji yang berupa data sekunder, penelitian ini bisa dikatakan dengan penelitian kepustakaan (library research). Dan sumber data yang digunakan adalah data primer dan sekunder. Dengan demikian dari hasil penelitian mengenai nikah mut’ah terhasillah bahwasanya dalam Islam pernikahan kontrak sudah ditiadakan dan menyikapi hal tersebut undang-undang yang berlaku di Indonesia juga melarang terjadinya praktik kawin kontrak karena tidak sesuainya dengan asas atau landasan hukum negara Indonesia.

Introducción: Los alineadores se han vuelto una alternativa de preferencia en cuanto al tratamiento de ortodoncia y han superado la elección de brackets convencionales, debido a la comodidad y estética que representan; sin embargo, sigue siendo un tema controversial el resultado final con este sistema. El objetivo de esta revisión sistematizada fue verificar la efectividad del tratamiento finalizado con alineadores versus con brackets convencionales. Materiales y métodos: Se realizó una búsqueda exhaustiva en las bases de datos de PubMed, ScienceDirect, Scopus y Embase hasta la fecha del 5 de enero de 2023. Se incluyeron estudios comparativos que evaluaron el resultado final y el tiempo de tratamiento de los alineadores en comparación con los brackets convencionales. Dos investigadores seleccionaron cuidadosamente los artículos evaluados y analizaron diferentes tópicos clave sobre el tema. Resultados: En este estudio se incluyeron 8 artículos; según los estudios, la gran mayoría no encontraron diferencias significativas en la finalización entre los grupos comparados. Adicionalmente, el tiempo de tratamiento en 3 artículos fue más rápido con alineadores, en 3 artículos fue más rápido con brackets convencionales y en un artículo no se encontró diferencia significativa, por lo que aún no está establecido si un sistema es más rápido que el otro. Conclusiones: Tanto alineadores como ortodoncia fija convencional tuvieron buenos resultados en la finalización del tratamiento de ortodoncia y presentaron un tiempo de tratamiento semejante; sin embargo, la mayoría de casos tratados pertenecieron a maloclusiones de mediana a baja complejidad, por lo que no se puede generalizar estos hallazgos a todas las maloclusiones.

Published: July 2023

The complete bleeding in slaughtering animals is closely related to the halalness of the meat. This study aims to describe the completeness of blood drains in discarded laying hens carcasses sold at traditional markets in Banda Aceh City. The research samples were nine chicken carcasses bought from three traditional markets, i.e., Peunayong, Ule Kareng, and Seutui (three samples from each market). The study used a cross-sectional method to test the perfect carcass bleeding with the Malachite Green (MG) test in the form of seeing changes in the color of the solution. The results showed that all samples changed color from green to dark blue. A perfectly slaughtered chicken will not find hemoglobin in the chicken carcass, causing O₂ to oxidize malachite green to a dark blue, indicating that the slaughtering and bleeding occurred completely. In conclusion, the carcasses of discarded laying hens sold in the traditional markets of Peunayong, Ule Kareng, and Seutui are halal.
Optimized Finite State ASR Model for the Arabic Language
Authors: Sultan Wael , Ibrahim Othman , Abdou Sherif
Published: July 2023

Since its introduction, the Weighted Finite-State Transducers (WFSTs) networks, with their precompiled search space in a single finite state, have provided an exceptional performance with an order of magnitude faster decoders for Automatic Speech Recognition systems compared to the conventional systems that construct the search space progressively. Using WFSTs for morphology-rich languages such as Arabic faces the challenge of the large vocabulary that results in very large networks that are hard to fit in the memory of common CPUs. In this work, we introduce several approaches that have been used to reduce the size of large Vocabulary Arabic WFSTs with a very minor impact on the system accuracy. We adopted the star architecture for the network topology and that reduced the network size and increased the decoding speed. Also, we adopted a two-pass decoding approach that utilizes a short history language model, and consequently smaller network size, in the first pass then in the second pass rescore the produced lattice with the longer history language model. We investigated several tuning parameters to reach the best compromise between network size and system accuracy. Applying these results on two test sets has shown consistent results of a 45% overall reduction in network size with only less than 1% degradation in accuracy. On the standard MGB3 benchmark, we managed to get 40x real-time Arabic ASR with an accuracy of 83.67% compared to 85.82% of state-of-the-art systems that have only 8x real-time performance on common commodity CPU processors.

Potential for bias in (sero)prevalence estimates when not accounting for test sensitivity and specificity
Authors: Haile Sarah R
Published: July 2023

Background: The COVID-19 has led to many studies of seroprevalence. A number of methods exist in the statistical literature to correctly estimate disease prevalence in the presence of diagnostic testmisclassification, but these methods seem to be less known and notroutinely used in the public health literature. We aimed to show how widespread the problem is in recent publications, and to quantify the magnitude of bias introduced when correct methods are not used.
Methods: We examined a sample of recent literature to determine how often public health researcher did not account for test performance in estimates of seroprevalence. Using straightforward calculations, we estimated the amount of bias introduced when reporting the proportion of positive test results instead of using sensitivity and specificity to estimate disease prevalence.
Results: Of the seroprevalence studies sampled, 80% failed to account for sensitivity and specificity. Expected bias is often more than is desired in practice, ranging from 1% to 10%.
Conclusions: Researchers conducting studies of prevalence should correctly account for test sensitivity and specificity in their statistical analysis.

Graph-based representations of speech signals: A novel approach for emotion recognition
Authors: Pentari Anastasia , Kafentzis George , Tsiknakis Manolis
Published: July 2023

Speech emotion recognition (SER) has gained an increased interest during the last decades as part of enriched affective computing. As a consequence, a variety of engineering approaches have been developed addressing the challenge of the SER problem, exploiting different features, learning algorithms, and datasets. In this paper, we propose the application of the graph theory for classifying emotionally-colored speech signals. Graph theory provides tools for extracting statistical as well as structural information from any time series. We propose to use the mentioned information as a novel feature set. Furthermore, we suggest setting a unique feature-based identity for each emotion belonging to each speaker. The emotion classification is performed by a Random Forest classifier. The proposed method is compared with two state-of-the-art approaches involving well known hand-crafted features as well as deep learning architectures operating on mel-spectrograms. Experimental results on two datasets, EMODB (acted) and DEMoS (in-the-wild), reveal that our proposed method is capable of addressing the SER problem in a more effective manner than existing approaches.

Published: July 2023

This study introduces a novel deep modeling methodology for six-degree-of-freedom rigid body dynamics, utilizing energy variation estimation in Hamiltonian neural networks. The method addresses challenges, such as modeling complexity and accuracy, in controlled rigid body dynamics across diverse fields like aerospace, robotics, and automotive engineering. Our approach is based on Hamiltonian dynamics principles and addresses the modeling issue of time-varying energy due to control by constructing an inductive bias that captures the energy variation information of rigid bodies. The proposed methodology not only achieves highly accurate modeling but also preserves bidirectional time sliding inference inherent in Hamiltonian-based modeling approaches.Experimental results show that our method outperforms existing approaches in six-degree-of-freedom dynamic modeling for aircraft and missiles, achieving high-precision modeling and feedback rectification. Our findings hold significant potential for military applications. Future research will focus on optimizing the proposed methodology to enhance the model's accuracy and robustness, enabling more precise and efficient rigid body control.
A House Divided: Cooperation, Polarization, and the Power of Reputation
Authors: Fekete Sándor , Wild Sebastian , Keldenich Phillip , Spiess Jann , Schlund Maximilian , Costard Jano , Radbruch Jonas , Stursberg Paul
Published: July 2023

Altruistic cooperation has enabled humans to thrive1. However, the interaction of sentient individuals faces the dilemma of limiting the downsides of personally beneficial, but globally detrimental selfish behavior without causing even more damage through escalating conflicts. The evolution of cooperation has been studied in non-zero sum games, with the Prisoner’s Dilemma, “the E. coli of social psychology”2, providing a fundamental test case. Typically3-12, interactions between individuals may (i) occur repeatedly, (ii) involve groups of individuals, (iii) be subject to evolutionary mechanisms, often based on the study of equilibria for homogeneous settings.13 However, a better understanding of the non-equilibrium dynamics of cooperation in structured environments is crucial for further progress. Here we consider an inhomogeneous, spatial, dynamic setting, in which evolution occurs not necessarily at an equilibrium. We demonstrate how minimal, publicly observable information on previous behavior can be exploited to outperform alternatives, achieving evolutionary performance similar to clandestine, membership-based strategies. We also show how polarization (with a cooperating population disintegrating into competing factions) and tribalism (with cooperation solely based on group membership instead of behavior) can arise, how these phenomena can be overcome with two additional mechanisms, and how cooperation can erode. Our results demonstrate how cooperation, reputation, polarization and tribalism are intricately linked, even in a simple mathematical model in which they arise in absence of complex psychological mechanisms. This provides a fundamental explanation for how robust cooperation may break down when faced with eroding universality of globally recognized values and of local, direct reciprocity; it may also help to prevent behavior-based reputation systems from giving way to emergent polarization and, ultimately, purely membership-based tribalism. We also anticipate that our methods will be of critical importance for the design and implementation of artificial structures based on the interaction of many independent, self-interested virtual agents.
On the Building of Each Psychologist`s Approach
Authors: Abumanssur Mateus Elias , Simão Livia Mathias
Published: July 2023

Psychology is divided in different systems, each a tradition with its own postulates, assumptions, methodology, themes and ethics. This division, not being purely theoretical, is built into the institutionalisation of psychology, shaping career paths and identities within this field. For the individual psychologist, positioning herself in relation to those dividing lines is a practical imposition. But the experience of what those divisions are, what they represent, and how such choices are made, varies greatly from one psychologist to another, and we are not fully self-conscious of the process. In this research, developed in the framework of semiotic cultural constructivism, we interviewed two acting psychologists on their own experiences, and, through the dialogue with what they and other authors brought, propose a few processes and dimensions to conceptualise our qualitative understanding of how psychologists build their own theoretical positioning within psychology, as a process that happens both in individual and collective dimensions. Finally, we bring considerations on what our standpoint implicates for the learning, the institutionalisation and the theoretical negotiation of psychology.
The Face-in-the-Crowd attentional bias modification task improves mood but not through modified attentional biases: a randomised experimental trial
Authors: Skvarc David R. , Hyder Shannon , Hayley Alexa
Published: July 2023

Attentional and cognitive biases related to psychological distress have been modified in clinical samples. This study investigates whether such biases can be detected and changed in a community sample and whether such training can reduce psychological distress. Participants were randomly assigned to an experimental or control condition and assessed at baseline, seven days, and 30 days follow-up. We operationalised attentional biases as target search latency in milliseconds. Results showed limited evidence of attentional biases in participants with higher trait mood distress. However, significant correlations were found in the experimental condition at day thirty, indicating a relationship between task latency and stress, as well as changes in latency and depression. Curiously, we observed some evidence of improvement in mood after the intervention. Participants in the control condition reported the greatest improvements in mood and psychological distress, while effects in the experimental condition were largely changes in attentional biases. These findings suggest that while attentional biases associated with psychological distress are obscured in community samples, the use of a bias modification intervention can be effective in eliciting a positive bias which, in turn, improves mood. This study highlights the potential for attentional bias modification in treating psychological distress symptoms.

Published: July 2023

To address the issues of severe fragmentation of Traditional Chinese Medicine (TCM) prescription knowledge and single knowledge representation, a standardized and visualized prescription knowledge graph is created by extracting the medical case data and prescription information based on the TCM medical cases and prescription codices, and incorporating external knowledge, such as prescription ion-evidence relationships. The collected and organized prescription data is initially recognized and extracted from the entities to obtain attributes like prescription name, composition, function and treatment, symptoms, etc. Second, a knowledge graph of prescriptions is constructed top-down, and Neo4j's Cypher is used to manipulate and visualize the prescription data. Finally, the tongue image samples are trained for tongue image discrimination using the Faster R-CNN of deep learning. Based on the fusion of tongue results, a prescription knowledge graph recommendation system for tongue diagnosis is created. To improve the clinical analysis of TCM diagnosis, the system can use to carry out operations like querying prescription information and automatically generating prescription recommendations based on the results of the tongue diagnosis. The results in the realization of personalized treatment method ds in TCM and a new idea and method for prescription recommendation in TCM.

The concept of Internet of Things (IoT) and its countless applications are considered as an inseparable part of modern technology era. The placement of IoT- based devices and their limitations make the environment more vulnerable due to its openness. Security plays a critical role in IoT applications due to pervasiveness of the IoT in all of the aspects in daily life. from the other hand final devices such as their limited computing power, large number of devices connected to each other, and communication between devices and users do not allow for using traditional methods to solve security issues. Intrusion detection systems (IDSs) which can separate malicious traffic from normal mode are among the effective solutions in this field. the installed IDS should be highly accurate and light weight to affect accuracy. In order to bring services closer to electronic devices, a concept called "fog" has emerged. A large number of studies have been conducted to make the light IDS for IoT network utilizing various methods. The present study aims to propose two-layer hierarchical IDS based on machine learning, which detects attacks by considering the limitations of IoT resources. In order to create an efficient and accurate IDS, the combination of two improved K-nearest neighbor (KNN) algorithms and multi-layer perceptron (MLP) neural network applied in the fog and cloud to separate the attacks from normal traffic, respectively. we evaluated our proposed method using IOT23 dataset. The results prove the improvement in accuracy, compared to the previous methods.
Direct power decoupling control using optimal switching table combined with virtual flux estimator for PWM rectifier
Authors: Bouaziz Bechir , Bacha Faouzi
Published: July 2023

This paper presents the design and implementation of a Direct Power Control (DPC) based on virtual flux estimator and optimal Switching Table (VF-ST-DPC) for a three phase PWM rectifier. The proposed approach is based on the combination of the DPC technique principle, virtual flux estimator technique and an optimal switching table (ST) to select the optimal converter vector control. The objectives of approach are to solve the cross-coupling between the instantaneous active and the reactive power for each sector and improve the harmonic line currents. Thus, the proposed method is realized in the fixed coordinate frame, so, does not require Park’s transformation and the voltage grid synchronization is achieved by a virtual flux estimation method. Both, experimental results based on the dSPACE DS1104 card show that the VF-ST-DPC guarantees a smooth and decoupled control of instantaneous active and reactive power and provide a low harmonic (THD = 4.6%) by verifying the expected performances of the proposed method under steady-state and transient operation.

A high-gain cubic boost converter (HG-CBC) with hybrid-based maximum power point tracking (MPPT) through a neural network (NN) aided by the P&O technique (HNN-PO MPPT) has been suggested to acquire optimum power from a solar photovoltaic (SPV) model under varying climatic conditions. The SPV's output is enhanced using the suggested HG-CBC as per the requirement. A detailed comparison of different conventional boost converters (BC) with the suggested HG-CBC is presented and it mainly highlighting on part count and boost factor (B). Using the MATLAB tool, the functionality of the developed HNN-PO MPPT technique has been examined for constant and different irradiation (G) levels. The hybrid-based MPPT helps quickly attain maximum power point (MPP) with minimum oscillations at the output. The convergence period is very short with high precision in comparison with P&O and NN MPPT. The results are examined between the suggested and traditional MPPT methods in relation to % of oscillations and rise time. The Reduced Switch Multilevel Inverter (RSMLI) is proposed to integrate the SPV with the RL load. The RSMLI is compared with the conventional standard five-level MLI in relation to the quantity of DC sources, diodes, switches, capacitors, and other parts utilized. The suggested MLI involves a reduced switch count, which mitigates the overall losses during switching and hence improves the efficiency of an inverter. MLI switches are controlled using a sine PWM modulation technique. The THD of output current of five-level RSMLI is 4.47% and it falls within the IEEE 519 norm. Hence, output power quality is enhanced.

The Metamaterial Absorber (MA) has emerged as a game-changing tool for various applications such as photodetectors, plasmonic sensors, energy harvesting, imaging, solar cells, optical modulators, and more. The proposed MA comprises a metal-dielectric-metal structure (Ni-SiO2-Ni) to achieve over 90% absorption bandwidth from 360 nm to 1750 nm. The average absorption at the operational wavelength is 94.47%, and a peak absorption of 99% appears at 900 nm. The designed MA shows polarization insensitivity and oblique incident angle stability up to 60˚. Parametric design analysis, electric field, magnetic field, surface current distribution, and temperature distributions have been investigated to comprehend the absorption characteristics of the MA. The Polarization Conversion Ratio (PCR) result shows the proposed MA as a perfect absorber rather than a polarization converter. The effect of concave and convex bending has also been investigated up to 16˚, validating the stable absorption behavior. Finally, the designed MA can be a potential candidate for visible and optical window applications such as solar energy harvesting, photodetectors, light trapping, etc.
Projectile Energy and Entrance Channel Mass-Asymmetry Effects on Incomplete Fusion of 12C + 169Tm, 16O + 169Tm and 16O + 75 As Systems at 4 — 7.5 MeV/Nucleon Energy Beam

This study focus on the correlation between entrance channel properties and incomplete fusion reaction. The dynamics of heavy-ion fusion reactions involved in the interaction of 12C and 16O with 169Tm and 75 As targets were examined at 3 — 8 MeV/Nucleon specific energies. The influence of projectile energy and entrance channel mass-asymmetry on the incomplete fusion process in the interaction of 12C + 169Tm, 16O + 169Tm and 16O + 75 As systems at energies ranging from 4 — 7.5 MeV/Nucleon was examined in this study. The PACE4 statistical model was used to compare and analyze the measured cross sections from the EXFOR data base. The values of level density parameter, which is a sensitive input parameter, were optimized using a representative non-a-emitting channel from the respective systems. The experimentally measured excitation functions for representative non α-emitting channels were found to be in good agreement with the theoretical predictions in general. However, for α-emitting channels in the current systems, the measured excitation functions were greater than the theoretical model code predictions, which could be attributed to incomplete fusion reaction at these energies. The observed enhancements in α-emitting channels were attributable to the contribution coming from incomplete fusion reactions. The incomplete fusion fraction, which explains the relative relevance of incomplete fusion processes, was attempted to be approximated. The incomplete fusion fraction was shown to be sensitive to the projectile energy and mass-asymmetry of the entrance channel. Further, the results showed that incomplete fusion reactions were higher for more mass-asymmetric systems than mass-symmetric one.

Volyn regional Museum archaeological collection on scientific periodical pages of Independence time
Authors: Verba Taras
Published: July 2023

The article examines Volyn regional Museum archaeological collection (hereinafter – VRM) through the prism of scientific researches published in domestic periodicals during the period of Ukraine's independence. The relevance of the research is related to the necessity of study and popularization of the transitive archaeological heritage, which performs important sociocultural functions, such as the restoration of historical memory and the preservation of cultural self-identification of identity, which is especially relevant due to modern events, the influence of neighboring cultures and growing globalization. During the research, author characterized the quantitative composition of VRM archaeological collection. At the end of 2022, it had 23,880 registration numbers, which makes the collection one of the largest archaeological collections in Western Ukraine. The author noted that the accumulation of archaeological objects inVRM collections did not go unnoticed by scientists from various cities and institutions. The results of their researches were usually published in the form of articles and reports in domestic scientific periodicals and magazines. The main tasks followed by the researchers were the involvement of the archaeological collection objects to the scientific circulation, their attribution clarification, comprehensive analysis of the incomes. The author assorted all scientific publications related to the VRM archaeological collection according to several criteria. One of the main ones is their writing form and style. Reviews and analytical publications are highlighted. In the first ones, authors described collections or selections of objects, characterized their external features and functional purpose. Most of them are written in short informative messages form. On the other hand, in analytical publications objects from different monuments were compared, was presented their in-depth interpretation, and were drown conclusions about particular ethno-cultural or ethno-historical issues. Almost all analytical publications are written as large scientific articles. Another important criterion for the publications systematization of the VHLM archaeological collection is the scientific publications type in which they were published. Conventionally, they can be divided into informative archaeological collections, regional historical and local history publications, all-Ukrainian specialist publications on archeology and ancient history. The largest number of articles written about the VRM collections belong to H. Okhrimenko, and they were also actively researched by the State Enterprise "Volyn Starozhytnosti" employees. Researchers paid special attention to materials from the Neolithic, Bronze Age, Middle Ages, and early modern times. Despite a significant number of publications, most objects from the VRM archaeological collection have not been introduced into scientific circulation, and many artifacts require re-attribution.
