Authors: Febrian  , Tony  , Perdana Novario Jaya
Published: November 2023

Pandemi Covid-19 membuat banyak kantor melakukan kebijakan work-from-home (WFH) dan ada juga beberapa perusahaan yang masih menerapkan work from office (WFO). Perbedaan pemberlakuan kebijakan ini disebabkan beberapa alasan, salah satunya adalah karena kurangnya pengawasan terhadap pekerjaan yang dilakukan oleh karyawan. Sehingga menyebabkan efek domino terhadap kegiatan pekerjaan lainnya. Permasalahan ini dapat dibantu dengan adanya sistem informasi manajemen pekerjaan. Berdasarkan kasus pada PT. Lyrid Prima Indonesia, sebuah sistem informasi manajemen pekerjaan diperlukan sebagai proses pengawasan terhadap pekerjaan karyawan. Pada sistem ini, terdapat fungsi seperti dashboard perkembangan setiap project, daftar project yang sedang dikembangkan, dan halaman perkembangan penyelesaian bug setiap project. Selain itu, terdapat pula paparan informasi untuk tiap peran akses seperti chart, informasi progress pekerjaan, dan informasi akun. Pengembangan sistem ini menggunakan metode SDLC dengan model waterfall. Sistem sudah melalui tahap pengujian UAT meliputi 5 role dan mendapatkan hasil persentase fungsionalitas sistem sebesar 100%, persentase fungsionalitas 100%, dan persentase usability sebesar 69%.

Published: November 2023

This research study attempts to explicate the aspiration of returning to pristine nature in Waubgeshig Rice’s novel Legacy by applying the theory of eco-criticism. As Indigenous texts represent the symbiotic relationship between culture and nature, which serves as an essential feature of the Indigenous people being their attempt to reconnect to nature through land. The purpose of this is gaining Indigenous identity, which has its origins in peace among all living things. This writing has been analyzed based on nature-centered concepts, traditional and cultural practices, environmental respect and knowledge, and dependency on nature and its resources as portrayed in certain important excerpts.  The study will demonstrate how Rice conveyed nature awareness by a simple depiction of the character’s harmony with their surroundings and how they find healing through nature. He demonstrates how the human’s connection with nature sheds light on postmodern themes such as identity and ethical decline. Rice promotes the idea that the environment plays a significant role as well as being a central factor in the Indigenous existence and how it has a direct influence on them. Discussing discrete characters and their various attributes, as well as the parts these characters are assigned in connection to the world around them through nature, is crucial to understanding the notion of man-environment interaction.

The relevance of the study is due to the increase in crimes on funds operating in non-cash form. In the future, the development of the digital economy will be associated with an increase in such risks. In this regard, the authors have made a comparison of the Russian and Chinese experience of their minimization. In both countries, there is a steady increase in the number of thefts committed using illegal access to digital payment systems. At the same time, criminal law norms designed to counteract fraudulent actions have certain drawbacks. The judicial interpretation of these norms is also ambiguous. In conditions of limited functioning of international payment systems, theft of non-cash funds can be committed in new ways. In the future, non-cash payments will increase in volume, so it is necessary to improve the security of their conduct. The authors used a comparative legal method, as well as analysis and synthesis, which made it possible to give the study a complete character. The article summarizes the Russian and Chinese experience in countering the theft of funds deposited in non-cash form. Since the share of non-cash payments in Russia and China is significant, not only economic entities, but also citizens are involved in their turnover. The latter, not having financial literacy, can become victims of fraudsters. The state policy regarding the regulation of non-cash payments is built in the direction of establishing control over the functioning of electronic platforms. However, this does not seem to be sufficient, since it does not reduce financial risks. The criminal legal field remains virtually the only lever to counteract this type of theft. At the same time, the structure of the criminal law prohibition does not reflect the nature and degree of public danger of fraudulent actions and does not clearly distinguish them from secret theft.
Income tax deduction as a tool to mitigate catastrophic health expenditure for cancer care falls short of its purpose in India
Authors: Ghoshal Arunangshu , Saji Edwin , Mathew Aju
Published: November 2023

Income tax deductions aimed at alleviating the financial strain of catastrophic health expenses, prove inadequate in supporting cancer care in India. First, the stringent eligibility criteria for accessing this tax deduction restrict its availability to a narrow segment of the population. Typically, it is granted only to those who receive treatment at government-sanctioned medical facilities. Consequently, this deduction excludes a substantial number of patients, intensifying their financial woes. Moreover, the maximum deduction amount, despite sporadic revisions, falls short in the face of skyrocketing cancer treatment costs. The current structure of the income tax deduction does little to alleviate this burden, as the deduction often pales in comparison to the actual costs incurred. Rather than dissolution of this provision in the new tax regime, we propose a reform and reevaluation of the income tax deduction framework to ensure it genuinely fulfills its role in alleviating the financial strain of cancer care in India.

À l’amont immédiat de Liège, l’étude sédimentologique d’une succession de hautes terrasses de la Meuse a conduit à confirmer des étapes de l’évolution du bassin. Les plus hautes terrasses ont été développées par la Meuse qui prenait sa source sur le flanc nord du Massif de Rocroi (Meuse de Dinant). Le cailloutis de plateau (Fontaine à 200 m) plus fin que tous les suivants est rapporté au rivage de la mer chattienne en régression. Au cours de l’incision jusqu’à 170 m, la rivière a surtout remanié le cailloutis sublittoral précité en y ajoutant des éléments un peu plus grossiers. Le cailloutis de la terrasse suivante (Chokier-Haut à 165 m) est fondamentalement différent ; il comporte une composante nouvelle originaire des massifs de roches métamorphiques de Haute Belgique qui devrait répondre à la capture de la Semois.

Revealing Large Room-Temperature Nernst Coefficients in 2D Materials by First-Principles Modeling
Authors: Rezaei S. Emad , Schindler Peter
Published: November 2023

Two-dimensional (2D) materials have attracted significant attention owing to their distinctive electronic, thermal, and mechanical characteristics. Recent advancements in both theoretical understanding and experimental methods have greatly contributed to the understanding of thermoelectric properties in 2D materials. However, thermomagnetic properties of 2D materials have not yet received the same amount of attention. In this work, we select promising 2D materials guided by the physics of the Nernst effect and present a thorough first-principles study of their electronic structures, carrier mobilities, and Nernst coefficients as a function of carrier concentration. Specifically, we reveal that trilayer graphene with an ABA stacking exhibits an exceptionally large Nernst coefficient of 112 μV/(KT) at room temperature. We further demonstrate that monolayer graphene, ABC-stacked trilayer graphene, and trilayer phosphorene (AAA stacking) have large Nernst coefficients at room temperature. This study establishes an ab inito framework for the quantitative study of the thermomagnetic effects in 2D materials and demonstrates high fidelity with previous experimental data.
Assessment of embedding schemes in a hybrid machine learning/classical potentials (ML/MM) scheme

Published: November 2023

Machine Learning (ML) methods have reached high accuracy levels for the prediction of in vacuo molecular properties. However, the simulation of large systems through solely ML methods (like those based on neural network potentials) is still a challenge. In this context, one of the most promising frameworks for integrating ML schemes in the simulation of complex molecular systems are the so-called ML/MM methods. These multiscale approaches combine ML methods with classical forcefields (MM), in the same spirit as the succesful hybrid quantum mechanics-molecular mechanics methods (QM/MM). The key issue for such ML/MM methods is the adequate description of the coupling between the region of the system described by ML and the region described at the MM level. In the context of QM/MM schemes, the main ingredient of the interaction is electrostatic, and the state of the art is the so called electrostatic-embedding. In this study, we analyze the quality of simpler mechanical embedding-based approaches, specifically focusing on their application within a ML/MM framework utilizing atomic partial charges derived in vacuo. Taking as reference electrostatic embedding calculations performed at a QM(DFT)/MM level, we explore different atomic charges schemes, as well as a polarization correction computed using atomic polarizabilites. Our benchmark data set comprises a set of about 80k small organic structures from the ANI-1x database, solvated in water. The results suggest that the MBIS atomic charges yield the best agreement with the reference coupling energy. Remarkable enhancements are achieved by including a simple polarization correction.

Herein we report on a robust microporous aluminum tetracarboxylate framework, MIL-120(Al)-AP, (MIL, AP: Institute Lavoisier and Ambient Pressure synthesis, respectively), which exhibits high CO2 uptake (1.9 mmol g-1 at 0.1 bar, 298 K). In situ Synchrotron X-ray diffraction measurements together with Monte Carlo simulations reveal that this structure offers a favorable CO2 capture configuration with the pores being decorated with a high density of µ2-OH groups and accessible aromatic rings. Meanwhile, based on calculations and experimental evidences, moderate host-guest interactions Qst (CO2) value of MIL-120(Al)-AP (~40 kJ mol-1) is deduced, suggesting a relatively low energy penalty for full regeneration. Moreover, an environmentally friendly ambient pressure green route, relying on inexpensive raw materials, is developed to prepare MIL-120(Al)-AP at the kilogram scale with a high yield while the MOF is further shaped with inorganic binders as millimeter-sized mechanically stable beads. First evidences of its efficient CO2/N2 separation ability are validated by breakthrough experiments while IR operando experiments indicate a kinetically favorable CO2 adsorption over water. Finally, a techno-economic analysis gives an estimated production cost of about 13 $/kg, significantly lower than for other benchmark MOFs. These advancements make MIL-120(Al)-AP an excellent candidate as an adsorbent for industrial scale CO2 capture processes.
Appropriateness of Surgical Antimicrobial Prophylaxis in a tertiary care hospital: A prospective observational study
Authors: K Shailaja , D Fragrance Jemimah , L S Aritta Hillari , N Priyanka
Published: November 2023

Surgical site infections (SSIs) are a significant concern in global healthcare, particularly in middle and low-income countries, leading to increased hospitalizations, morbidity, mortality, and financial strain. Ranked third in the CDC's National Nosocomial Infections Surveillance System, SSIs have prompted a focus on preventive measures, notably surgical antimicrobial prophylaxis (SAP). However, SAP is often used inappropriately, contributing to the rise of Antimicrobial Resistance (AMR). Addressing this, a six-month prospective observational study was conducted in a tertiary care hospital to assess the adherence to SAP guidelines among 386 patients undergoing surgeries in various specialties. The study aimed to evaluate the appropriateness of SAP practices and identify factors leading to non-compliance. Results showed that only 58.3% of patients fully adhered to the guidelines. While 100% compliance was observed in SAP indication, lower adherence was noted in the timing of administration (97.7%), choice of SAP (85%), and duration of prophylaxis (70.2%). These findings underscore a significant gap between recommended SAP practices and actual implementation. This gap highlights the need for stronger Institutional Antimicrobial Stewardship (AMS) programs and the critical role of clinical pharmacists in regularly evaluating SAP and prescribing practices. To combat the rise of antibiotic resistance while ensuring patient safety, enhancing SAP practices in line with national and international recommendations is essential. The study advocates for more active interventions at the time of order to optimize antibiotic use, thereby addressing the challenge of compliance in SAP guidelines.
One Name, One Person: The Problem of Reconstructing the List of Early Kings of Piedras Negras in Light of the Hieroglyphic Texts from Yaxchilan
Authors: Styuflyaev Maksym
Published: November 2023

This article is concerned with an important episode in the early history of two neighboring kingdoms located in the western part of the Maya lowlands: Yaxchilan and Piedras Negras. The two sites were at war with each other and sought dominance in the Upper Usumacinta region for almost the entire duration of Classic Maya history (3rd to 10th centuries AD). The article examines some controversial issues related to the founding of the Yaxchilan and Piedras Negras dynasties and highlights the initial stage of their military confrontation, which took place in the second half of the 5th century. It is shown that the founders of both royal houses were probably of non-local origin, having arrived in their new capitals from elsewhere. The main sources used in this work are hieroglyphic inscriptions from Yaxchilan: lintels 11, 35, 37, and 49 and Hieroglyphic Stairway 1. These texts contain a list of local kings and a brief description of their military triumphs. In particular, it is mentioned that Jatz’oom Jol, the seventh ruler of Yaxchilan, and his successor Yaxuun Bahlam II gained victories over Piedras Negras and seized important captives. A ruler of Piedras Negras called Itzam K'an Ahk is mentioned in connection with both wars. Jatz’oom Jol captured Itzam K'an Ahk himself in the second half of the 450s at the earliest, and Yaxuun Bahlam II captured a military commander who served Itzam K'an Ahk in the late 460s or 470s. The opinion that two different rulers who successively sit on the throne of Piedras Negras, Itzam K'an Ahk I ("Ruler A") and Itzam K'an Ahk II ("Ruler B"), are mentioned on the Yaxchilan triumphal monuments is firmly established in historiography. However, having two successive Maya kings with the same name on the throne would have run contrary to the established practice of changing regnal names: the direct heir to the throne never repeated the name of their predecessor in the history of Yaxchilan and Piedras Negras. Besides that, the monuments from Yaxchilan only mention the capture of the enemy king, not his death. Maya history is replete with examples of defeated rulers returning home after being captured and ruling their kingdoms for many more years. This is what may have happened to Itzam K'an Ahk I. However, there is a plausible explanation for his being mentioned twice that is even simpler. Subordinate rulers and dignitaries in Classic Maya society maintained a personal relationship with their overlords even after the death of the latter. A military commander from Piedras Negras could remain a man of Itzam K'an Ahk I even if his suzerain had died in captivity long before the second war. Therefore, there are no sufficient grounds for distinguishing between the early Piedras Negras kings Itzam K'an Ahk I and Itzam K'an Ahk II. It is much more likely that the same person, namely the enemy king Itzam K'an Ahk I, is mentioned in the inscriptions in Yaxchilan and the list of rulers of Piedras Negras requires correction.
The foreign policy of Klemens von Metternich in the works of V. K. Nadler (1840–1894)
Authors: Lyman Serhii
Published: November 2023

The foreign policy activities of Klemens von Metternich, the main organizer of the Congress of Vienna, the true architect of the post-Napoleonic international order, and minister of foreign affairs and chancellor of the Austrian Empire, attracted the attention of many researchers, especially on the eve of his 250th birthday anniversary. The first monograph in Russian imperial historiography entirely devoted to Metternich's diplomacy was authored by the Kharkiv University professor V. K. Nadler (1840–1894); but this aspect of Nadler’s scholarship is largely unknown today. The purpose of this article is to comprehensively analyze Nadler's works dealing with Klemens von Metternich's diplomatic legacy and its significance for the further development of the post-Napoleonic international order. The author employs the methods of historical and comparative analysis, systematization and generalization, and retrospective analysis. The article shows that, in addition to the specialized study on Metternich and the European Reaction (1882), Nadler partially devoted the multi-volume monograph Emperor Alexander I and the Idea of the Holy Alliance to the analysis of the foreign policy of the Austrian Empire in the first years of the Vienna System of international relations. Nadler tried to avoid exaggerating the role of the individual in history, in the best progressive tradition of the historiography of his day. However, to denote the new international order, Nadler usually used the name «Metternich's political system», thus stressing the crucial importance of the Austrian minister as the organizer of the Congress of Vienna, the guarantor of the implementation of its decisions, and the driving force behind the fight against any dissent in European countries. According to Nadler, while the Vienna international order initially developed precisely in the reactionary direction mapped out by Metternich, the Greek Revolution and the Adrianople Peace Treaty of 1829, which confirmed the autonomy of Greece, struck a real blow to the «Metternich system».
Women’s Religious Schools in the Ukrainian Lands (1854–1918) in Modern Historiography
Authors: Nyzhnikova Svitlana
Published: November 2023

The historiography of women’s religious schools began to emerge simultaneously with the creation and functioning of these educational institutions in the second half of the 19th and early 20th centuries. Individual works from this period contain ample and interesting factual material, including statistical data on the numbers of students and teachers. In the Soviet period, the study of this subject ceased, because women’s religious education was not among historians’ research interests at this time. The current period in the historiography of the problem began with the first years of Ukrainian independence. During the past three decades, a number of works of various formats on the history of education have been produced, but neither diocesan women’s schools nor women’s schools of the Department of Religious Affairs receive much attention in these studies. Usually, authors either limit themselves to listing the basic facts from the history of these institutions or do not mention them at all. The development of gender studies and the appearance of works on women’s history also have failed to significantly affect the historiography of women’s religious schools, as researchers continued to use approaches traditional for history of education, such as the study of the educational process or characterization of an institution’s student body and faculty. Since the 2000s, works begin to appear that focus specifically on the system of women’s religious education in the Ukrainian lands. A significant achievement of these works has been the accumulation of various statistical materials important for the comparative analysis of women’s religious schools. However, they also for the most part reproduce methods and approaches characteristic of 19th-century historiography, enumerating the basic facts from the history of these schools without proper analysis. Further, we may sometimes come across characterizations of women’s religious schools that are not grounded in careful analysis or backed by appropriate sources. Still, in recent years there have been positive changes in the study of the diocesan schools and schools of the Department of Religious Affairs, such as attention to new themes and the use of interdisciplinary approaches. Overall, the subject remains promising for further research.
Morphology of fibrous structures formed in the course of superplastic deformation of the 01420T alloy with the original bimodal grain structure
Authors: Poyda V.P. , Milaya D.E. , Poyda A.V. , Petrushenko S.I.
Published: November 2023

The morphology of the fibrous structures formed in the working parts of the 01420T alloy samples with the initial bimodal grain structure, deformed to fracture under optimal conditions of superplastic deformation at a temperature Т = 520°С and flow stress σ = 4,5 MPa is investigated. The maximum elongation of specimens deformed to failure δ is 670%. It has been suggested that the specific type of fibrous structures found in the specimens of the investigated alloy 01420T probably depends on the volume of the metastable liquid-solid phase, which was concentrated in the form of inclusions at some grain boundaries and made a viscous flow during superplastic deformation, its shear viscosity , the characteristics of its surface tension, the degree of dynamic oxidation of the melt, and the kinetics of the development of this process. The final view of the fibers and their shape, likely, depends not only on the nature of the viscous flow of the liquid-solid material, but also on the process of its crystallization during the cooling of the specimen in air to room temperature after mechanical tests. It was found that in view, all fibrous structures found in the working parts of the specimens can be conditionally divided into the following: cylindrical fibers; tapered fibers; cylindrical fibers on which there is a thickening or one or more drop-like formations; ribbon-like fibers; fibers that look like stalactites or stalagmites. The reasons for the formation of cracks on ribbon-like fibers are considered. It is assumed that they were formed as a result of relaxation of internal stresses, which were not fully minimized in the course of recrystallization, which was carried out when the sample was cooled. The reasons for the formation of droplets on the fibers are considered. It has been suggested that fibrous structures similar to stalactites and stalagmites were formed from a viscous material, which, in the course of superplastic deformation, as a result of crystallization, occured in local microvolumes of fibers, gradually turned from liquid-solid to solid-liquid. This led to the fact that in the crystallized microvolume of this fiber, the viscous homogeneous flow of the material probably turned into a localized flow, which is characteristic of the plastic flow carried out as a result of displacement of dislocations in the solid phase, and leads to the formation of stalagmitic fibers.

Back-analyses of soft soil failure with "strain-softening" behavior by the "equivalent sensitivity" concept
Authors: Silva Lennon , Pacheco Marcus
Published: November 2023

Stability analyses of slopes in soft soils are usually affected by strain-softening, resulting in unrealistic (unconservative) safety factors. The loss of post peak strength cannot be accounted for by classic limit equilibrium analyses. In practice, however, the overall loss of soil strength is generally approximated by Bjerrum correction factor μ ≤ 1, which is believed to account for the different failure velocities during the field tests (usually vane tests) and the actual failure in the field, in addition to anisotropy (Schnaid & Odebrecht, 2012). The objective of this work is to demonstrate that strain-softening reduces the overall safety factor to a value nearly equivalent to the application of Bjerrum’s correction factor. To accomplish this, a simple constitutive model (Mohr-Coulomb with residual stress) is used for total stress finite element analyses by means of the concept of “equivalent sensitivity” proposed by Pereira Pinto (2017). The results showed that equivalent sensitivity can be a great instrument to simulate the strain-softening behavior of soft soils.

Tlogowatu Village, Kemalang District, Klaten Regency, is located on the slopes of Merapi Mountain. Currently, sand and stone mining from Merapi Mountain is the primary commodity produced by Tlogowatu Village. If this condition continues, it will cause the damage to the environment. Therefore, several community leaders have cultivated the stingless bee (Trigona laeviceps) as an economic source while adhering to ecological principles through stingless bee farming in community forests. However, community forest and stingless beekeeping need to be appropriately managed, especially in terms of management, production, and marketing aspects. Activities are carried out in several stages, namely starting with pre-activity surveys, counselling and practical development of management, production and marketing aspects, as well as monitoring and evaluation of activities. This activity has increased the knowledge of target partners regarding the livestock of Clanceng in community forests in the form of another type of Clanceng, namely T. biroi, various feed sources, techniques for breaking up split rapid colonies, and good honey packaging. Apart from that, through klanceng livestock in community forests, local communities also gain ecological benefits and build potential for developing agricultural education tourism (edu-agro-tourism) areas.

Objetivo: Diseñar un programa de intervención a través de diferentes estrategias que permitan promover el bienestar de las personas cuidadoras de la institución FANDIC. Metodología: Es un proyecto de gestión de desarrollo social, basado el enfoque ZOPP al analizar, organizar información y tomar decisiones a partir de los puntos de vista de actores involucrados, las realidades del contexto y la flexibilidad de las técnicas empleadas; para la recolección de información se emplearon herramientas de tipo cualitativa a través de grupos focales y entrevistas semiestructuradas; su alcance fue la realización del diseño del programa. Resultados: Se identificó que la institución FANDIC ha centrado sus procesos en las personas con discapacidad y no cuenta con un programa estructurado dirigido a personas cuidadoras, evidenciando necesidades importantes relacionadas a sus estados de salud física y mental mostrando signos de alarma relacionados al síndrome del cuidador quemado; También se observó brechas significativas en las cuidadoras(es) desde la familiarización y feminización del cuidado hasta la vulnerabilidad a nivel socioeconómica, así mismo se mantienen paradigmas de cuidado a la discapacidad desde un modelo de rehabilitación. Conclusiones: Desde salud pública, dar una respuesta a las necesidades requiere de soluciones estructurales donde se garantice el ejercicio de sus derechos, teniendo en cuenta la protección y la promoción de la salud, hasta su participación en la vida social, educativa, laboral y política, implicando a su vez que el rol del cuidador sea reconocido desde un área de trabajo remunerado y se desvincule de la familiarización y feminización del cuidado. Este proyecto responde a necesidades específicas identificadas e intereses de la institución lo que hace que se convierta en un proyecto viable y factible; a partir de allí se construyó el programa CALMA (Cuida Ahora la Manera de Apoyar).

Objetivo: Avaliar a associação da concentração de Cromogranina A com a ansiedade e estresse em profissionais de enfermagem e a associação da ansiedade e estresse com fatores sociodemográficos, epidemiológicos e laborais. Método: Estudo transversal desenvolvido com 210 profissionais de enfermagem de uma instituição hospitalar do Sudeste de Minas Gerais, Brasil, entre 2018-2019, por meio de preenchimento de um questionário de caracterização, do Inventário de Ansiedade de Beck e do Inventário de Sintomas de Stress para Adultos de Lipp, bem como da coleta de saliva dos participantes para verificar a concentração de Cromogranina A dos participantes. Os dados foram analisados de forma descritiva e inferencial, com nível de significância de 5%. Resultados: A maioria dos profissionais apresentou estresse (58,1%) e ansiedade (51,9%). Fatores como faixa etária, número de filhos, tempo de atuação na instituição, carga horária de trabalho, falta de atividade física, uso de medicamentos e outro emprego, aumentaram as chances desses trabalhadores terem ansiedade e estresse em níveis mais altos (P 0,001). A Cromogranina A apresentou maiores alterações nos profissionais do turno da tarde. Observou-se associação entre o grupo que tinha estresse e ansiedade com a Cromogranina A, no turno da noite, bem como do grupo que tinha apenas ansiedade em horários do turno da manhã (P 0,05). Conclusão: Os profissionais apresentaram níveis de ansiedade e estresse, que foram associados às alterações da CgA em
alguns horários, demonstrando que essa proteína pode ser um possível biomarcador de ansiedade e de estresse.

La Biblioteca de la Universidad de Concepción es un tesoro invaluable dentro de nuestra casa de estudios. Desde su fundación en 1926, ha sido lugar de encuentro para generaciones de alumnos y docentes. En 1972, se inauguró el edificio actual en el campus Concepción, un acontecimiento que marcó el inicio del Sistema Integrado de Bibliotecas, conocidas por la comunidad como Bibliotecas UdeC. Para nuestros estudiantes, las Bibliotecas UdeC tienen un significado especial en su vida universitaria. Son espacios que consideran propios, aprecian y protegen. Son lugares destinados al estudio, trabajo colaborativo, vinculación e investigación, donde el conocimiento se adquiere de manera enriquecedora. El dinamismo y la diversidad definen la cotidianidad en las Bibliotecas UdeC. Los y las estudiantes conforman comunidades activas, curiosas y comprometidas. Con el objetivo de fomentar su conexión con estos espacios, la Dirección organiza periódicamente actividades para los usuarios y usuarias, quienes valoran enormemente las oportunidades de participación creativa. Así, además del tradicional "Concurso de Marcapáginas", que se celebra anualmente, hemos añadido una novedad: "BiblioCómic", la primera publicación en forma de libro que plasma de manera gráfica las experiencias y emociones de nuestros usuarios mientras disfrutan del entorno de las bibliotecas. Como Directora de las Bibliotecas UdeC, me enorgullece este logro, ya que representa una valiosa muestra de creatividad, talento y convivencia en nuestra comunidad estudiantil. Quiero asegurarles que esta es solo la primera edición de "BiblioCómic", y trataré de que hayan muchas más en el futuro. Les dejo, como siempre, la puerta abierta para sigan participando activamente con nosotros y nosotras en estas emocionantes iniciativas.

Authors: Omer Taha Ahmed Elmukashfi
Published: November 2023

There is a relation between many neuropsychiatric disorders and reduction in hippocampal volume. So, a protocol for researches in this area is highly needed. Study aimed to design and validate a protocol for hippocampal volumetry to facilitate manual segmentation of hippocampus region. It was a comparative study, carried at Diagnostic Imaging Clinic at Elmoalem Hospital; where 65 Sudanese individuals were surveyed in period (December 2021 –April 2022). Data was collected through master sheet for sociodemographic information, 3D magnetic resonance imaging for measuring hippocampus volume, and imaging acquisition. Software for measurements 3D slicer version (4.11) was used, where hippocampus is mapped by delineating its boundaries. Protocol was composed of mapping hippocampus. Mapping hippocampus: identify sagittal view, lateral fissure, temporal horn of lateral ventricle, hippocampus region, temporal and occipital horn of lateral ventricle, choroid plexus of lateral ventricle. Among these slides hippocampus has been delineated. Statistical Computing: Data was analyzed using SPSS version 23. Reliability test was performed by obtaining Cronbach’s alpha. Protocol considered reliable if value of Cronbach’s alpha is close to (+1). P-value ≤ 0.05 was considered statistically significant. Validation of Protocol: Calculation of hippocampus volume is valid as total volume correlates strongly with both right and left measurements (correlation coefficient 0.76 and 0.87 respectively and p-value <0.001). Reliability test was 0.85; which was close to (+1). Conclusion and recommendation: This protocol represents a valid, reliable, and applicable method for measuring hippocampal volume. It could be a step to develop an international standard protocol for hippocampal volumetry.
