Epidemiological features and clinical profile of patients with thalassemia in Kabul, Afganisthan
Authors: Saeed Khwaja Mir Islam
Published: December 2024

Objectives:

Thalassemia is the most common genetic disorder globally. In Afghanistan, the epidemiology and clinical characteristics of the disease are not studied officially. This study aims to explore the epidemiological pattern and clinical profile of thalassemia patients registered in the National Blood Bank (NBB), Kabul, Afghanistan.

Material and Methods:

A retrospective medical record review was conducted to analyze registries and conduct phone calls for follow-up patients registered in the NBB during 2019–2020 in Kabul. The confirmed case was any patient tested for fetal hemoglobin and blood film. Data were collected using a form matching the patient’s registers. Epi Info v.7 was used for data management and descriptive measures analysis.

Results:

Totally 411 patients with thalassemia were enrolled in the analysis. Out of all patients, 225 (54.61%) were male, with an overall mean age of 6.89 (±4.06) years. The highest proportion of patients was clustered around age groups of 2–8 years (56%). Pashtuns’ ethnicity had the highest percentage of patients (63%) and Hazara the lowest (1%). Almost the majority of cases under management were thalassemia major (98.8%), and just one case was recorded as intermedia and four cases as minor. According to laboratory tests, 88 (21.4%) were positive for hepatitis C, 2 (0.5%) positive for hepatitis B, and 1 (0.2%) for human immunodeficiency virus. As a whole, 251 (61.67%) had a type of consanguinity marriage. In patients, the blood groups of A+ (27%), B+ (27%), and O+ (25%) were almost equally distributed, while AB+ (10%), O negative (4%), A negative (2%), and AB negative (0.2%) had low proportions. The residency of the majority (87.13%) was Kabul. Totally, 18 (4.36%) had surgical operations, and 11.8% reported children died due to thalassemia.

Conclusion:

Thalassemias are common in Afghanistan, and facility for management is lacking. Consanguineous marriage was more common and probably a contributing factor to disease. The establishment of more centers and a full review of factors are recommended.

Published: December 2024

Myelodysplastic syndrome (MDS) is a heterogeneous disorder with a significant risk of progression to acute myeloid leukemia. We present a case initially suspected of acute leukemia, subjected to comprehensive cytogenetic, immunophenotypic, and molecular evaluations. Cytogenetic analysis revealed a complex karyotype including translocation t (1;3) (q42;q21), near-tetraploidy, and deletions on chromosomes 5q and 20q. Fluorescence in situ hybridization confirmed the 5q and 20q deletions, along with trisomy 8. Immunophenotyping identified 7.5% abnormal myeloid blasts. Next-generation sequencing detected pathogenic TP53 mutations: c.569 (p.Pro190LeufsTer57) and c.464C>A (p.Thr155Asn). In addition, renal imaging showed mildly raised echotexture. This case underscores the value of integrated multimodal analysis for precise diagnosis and management of MDS, offering insights into its complex genetic landscape.

Published: December 2024

Improving timeliness represents a critical opportunity to maximize patient experience, quality of care, and overall health of a co-located multidis­ciplinary cancer (MDC) program. The primary objective was to develop a timeli­ness dashboard using a primary nursing care coordination model to track met­rics selected for care efficiency. The secondary objective was to identify whether timeliness improved with implementation of an MDC clinic with expanded visi­bility to care coordination. A nursing care coordination model was developed to perform data collection alongside frontline patient care to track patients’ jour­ney with cancer. A spreadsheet was first used but then transitioned to a web-based database based on nursing feedback. Timeliness metrics were collected from May 2019 through April 2023 with descriptive analysis performed to iden­tify trends. Results signify implementation of a co-located MDC with primary nursing care coordination has improved timeliness. The project showcases the importance of nursing care coordination in a high-volume clinic with increased visibility to patients’ journeys with cancer. It also demonstrates establishing and updating standardized work procedures for data collection, cleaning, and analy­sis for quality of care monitoring.
Cost and Clinical Implications of Utilizing Homologous Recombination Deficiency Status to Guide First-Line Maintenance Therapy Selection in Advanced Ovarian Cancer

Published: December 2024

Questions remain about the cost of homologous recombination de­ficiency (HRD) testing to guide the prescribing of poly (ADP-ribose) polymerase (PARP) inhibitors as first-line maintenance for advanced ovarian cancer (AOC). This model evaluates the cost of an HRD biomarker-guided (BMG) approach (olaparib for BRCA-mutated; olaparib and bevacizumab for HRD-positive BRCA wildtype; bevacizumab for HRD-negative) vs a non-BMG approach (niraparib for all patients) for 100 patients with newly diagnosed AOC. The model uses a Mar­kov structure with a US payer perspective and assumes comparisons between therapies based on extrapolated clinical trial results, real-world evidence, and published costs. Despite the upfront cost of HRD testing, a BMG approach is pro­jected to reduce total cost of care by $10 521 642 over 5 years ($51 633 928 vs $62 144 570) and increase progression-free survival in the AOC population (1699 vs 1523 months). This produces $26 in savings for every dollar spent on testing. These data suggest using a BMG approach based on HRD test results to pre­scribe first-line AOC maintenance therapy may reduce overall cost of care and improve clinical and economic outcomes.

Parijoto fruit (Medinilla speciosa Blume) is an endemic fruit around Mount Muria, Kudus, Central Java. The native people utilize Parijoto as traditional herbal medicine. Those utilization due to its metabolite compounds, such as tannin, flavonoid, fenolic, terpenoid, etc. In order to utilize Parijoto fruit properly, it is necessary to have an appropriate extraction and fractination method. So, the bioactive compounds of Parijoto fruit can be optimally extracted. The objective of this study is to obtain fractions of Parijoto fruit using three different solvent, methanol, ethyl acetate, and n-hexane. This study perform maceration as extraction method and liquid-liquid fractination to obtain the fractions. The dry simplicia yield was 85.49%. The maceration result was in the form of a blackish red green liquid with 67.45% yield. The methanol fraction was a thick blackish red liquid with 45.4% yield. While, the ethyl acetate fraction was a slightly fibrous viscous liquid with pinkish milk brown colour and 22.8% yield. On the other hand, the n-hexane fraction was a greenish viscous liquid with 13.8% yield. The highest yield is the result of fractination with methanol as a solvent because it is the most polar among others in this study. The solvent polarity is greatly affects the yield of fractination from natural product materials. In this study, the order of Parijoto yield from the highest to the lowest is methanol fraction, ethyl acetate fraction, and the last is n-hexane fraction. Those results were obtained due to the differences of each solvent polarity.

Published: December 2024

The results of the initial observations at SDN Ngepeh found several findings, namely the lack of optimal student involvement in learning, so that students are passive. Students cannot find their own knowledge and skills. Theme 1 learning activities show less than optimal results. This is because the learning method applied does not involve active student participation because the method used is the question assignment method, without being given appropriate materials or media. One effort to improve students' cognitive abilities and student activity is to use learning methods that are appropriate to the material to be taught by the teacher. The purpose of this research is to find out if the implementation of the problem-based learning method can improve student learning achievement and the activity of class VI SDN Ngepeh for the 2022/2023 academic year. This research is a classroom action research conducted at SDN Ngepeh in two cycles. This type of research is qualitative and quantitative research.

This study introduces a biocompatible, stimuli-responsive imaging and therapeutic delivery system using ultrasmall iron oxide nanoparticles (USPIONs) encapsulated within hyaluronic acid-b-poly(lactic acid) (HA-PLA) polymersome membrane and a model protein bovine serum albumin in the core. These multilamellar vesicles exhibit enhanced T2-weighted MRI contrast, achieving a relaxivity 3-fold higher than existing agents. The polymersomes demonstrate acid- and enzyme-triggered degradation, enabling controlled release and measurable contrast changes in pathological environments. Preliminary in vivo and postmortem studies confirm their strong imaging performance, high biocompatibility, and targeted response to enzymatic, acidic microenvironments, paving the way for theranostic applications in disease diagnosis and treatment monitoring.
Computational design of synthetic fluorescent nucleotides: tuning electron transfer and fluorescence competition with functionalization location of perylene tag
Authors: Effah Solomon Yamoah , Hix Mark A. , Walker Alice
Published: December 2024

Synthetic fluorescent nucleotides (SFNs) have a wide variety of applications in biochemical tracking, imaging, and diagnostic assays. There are many SFNs in active development to enhance their fluorescence wavelengths, environmental sensitivity, photostability, and photochemical/photoswitchable properties. However, there are few systematic theoretical studies of their fluorescence properties. In this work, we apply excited state QM/MM dynamics with TDDFT to nucleic acids tagged with perylene, which is particularly photostable, fluorescent and bright (fluorescence quantum yield = 0.94) in isolation. We probe the importance of geometry, dynamics, and functionalization location of the perylene tag on the nucleobase. We confirm charge transfer pathways consistent with previous experiments within our 2 ps timescale, and note that the directionality of the electron transfer stems primarily from the nucleic acid type. Additionally, we find that the functionalization point on specific nucleobases, along with key dihedral angles and orbital overlap, directly influences the probability of charge transfer and thus the final SFN fluorescence properties.

Published: December 2024

The palladium-catalyzed “regioreversed” α-hydroalkenylation and -hydroalkynylation of conjugated alkenes is re-ported. The unconventional selectivity of this reaction is achieved through the utilization of trans-spanning bidentate phosphine ligands that stabilize the proposed trans-Pd(II)Ln(R)(H) (R = alkenyl or alkynyl) intermediate. The α-hydrofunctionalization methods tolerate a variety of electron-deficient alkenes including α,β-unsaturated amides, esters and vinyl pyridines. A range of different alkenyl/alkynyl bromides are demonstrated to be effective coupling partners in the reaction. The phosphine-ligated palladium catalyst operates under mild weakly basic or neutral conditions and is resistant to air and moisture, giving rise to practical methodology for construction of β,γ-unsaturated carbonyl compounds.

Published: December 2024

We demonstrate the usefulness of general atom- and bond-level DFT descriptors to enhance the performance of neural networks for general reaction condition prediction. We treat reaction condition prediction as a multi-class classification task and report the performance of neural networks trained on 59,512 reactions with 283 distinct reaction condition classes and varying input embedding compositions. We show that by combining structural and general DFT descriptors in optimized ratios, models with input size up to 15% smaller than their purely structural counterparts can provide comparable recall, top-1 and top-3 accuracies. Moreover, we report improvements of up to 6%, 7% and 9% in weighted F1 score, top-1 accuracy and weighted recall, respectively, for neural networks trained on combined general DFT and structural descriptors when compared to purely structural models with equivalent architectures and input sizes. Remarkably, these results were achieved using a training set containing 267 times fewer data points than the one used for generating and embedding structural descriptors, despite both embedding strategies being similar unsupervised learning algorithms.

Verbalization of the concept of “hearing” in Slavic languages
Authors: Pedchenko Liudmyla
Published: December 2024

The purpose of this study is to identify the most productive cognitive-nominative models that form the core of the nominative field of the concept “hearing” in Slavic languages. The object of the study is the Slavic names of auditory perception. The subject of the study is the onomasiological structure of these names.

As a result of the research, it was established that the nomination models, according to which the concept of “hearing” is verbalized in Slavic languages, are few. Modern Slavic nominations of auditory perception belong to the all-Slavic vocabulary and have Proto-Indo-European roots.

The main Slavic name for the ability to hear – слух – is a verbal formation that implements the nominative model: ‘action’ > ‘ability to perform an action’. The semantic development of this lexeme (‘voice’ > ‘ability to hear’), the etymological connection of the lexemes слух, слава and слово, the combination of the meanings of ‘speak’ and ‘hear’ in the semantics of the Proto-Slavic verb *slūti indicate that this root in the Proto-Slavic language, the ability to perceive not just sounds, but the sounds of human speech was first noted.

From another Slavic verb denoting auditory sensations – чути – the abstract name of auditory perception was not formed in Slavic languages, which seems to be connected with the semantic syncretism of the ascending verb, which can be used in relation to different perceptual modes (touch, smell, hearing, etc.) or act as an undifferentiated designation of sensation.

When using the lexeme ухо in the sense of ‘hearing’, the model is implemented: ‘an organ performing a certain function’ > ‘function’, but this model is not productive in Slavic languages (recorded only in Russian). Since for the lexeme ухо the meaning ‘ability to perceive’ is not characteristic, in Slavic languages there are no names of deafness formed according to the model: ‘absence of an organ performing a function’ > ‘absence of a function’ (in contrast to the names of blindness, for which this model is productive).

From the onomasiological point of view, it is possible to ascertain the presence of two main cognitive features that influence the nature of the verbalization of the concept of “hearing” in Slavic languages: first, the obvious initial connection of auditory perception with human speech activity (the conceptualization of the human ability to hear was formed in connection connected with the development of articulate speech), and secondly, the semantic syncretism of perceptive vocabulary, which is based on the interaction of different perceptual modes of a person (the phenomenon of synesthesia).
Evaluation of the Seakeeping Performance Indices for Enhancing Crew Safety and Workability in Small Fishing Vessels
Authors: Park Dong-Woo , Lee Kidong , Seo Janghoon
Published: December 2024

This study evaluated the applicability of the seakeeping performance indices for assessing the safety and crew workability of small fishing vessels, considering the high incidence of accidents in this type of vessel and the limited research on the impact of vessel motion on crew safety. Hydrodynamic analyses of 16 fishing vessels were conducted and the responses of roll, pitch, MII (Motion induced interruption), and MSI (Motion sickness incidence) were derived under various environmental conditions. A three-dimensional panel method based on potential flow theory was used to assess the motion responses of the vessels. Viscous roll damping coefficients were derived from computational fluid dynamics simulations for three representative vessels and applied to the remaining vessels. The results suggested that the magnitude of the seakeeping performance indices varied according to the vessel dimensions and main particulars. In particular, MII exceeded the established criteria for most vessels except in the lowest environmental condition, highlighting the need for criteria specific to small fishing vessels. The study also examined the influence of the forward speed on the indices and found that roll and pitch responses increase with the speed while MSI decreases marginally. Overall, these findings may help enhance the safety of vessels and crew members in small fishing vessels.
Culture Representation Through Visual Images in The Korean Foundation Level 1 Textbook: A Multimodal Analysis

Published: December 2024

Abstract. This study aims to investigate culture representation through visual images in a Korean as a foreign language textbook for Indonesian students. It specifically exhibits how cultures are represented through visual images and how they are implicated to KFL learning. Culture and language are closely related, and understanding the cultural values underlying the target language can greatly affect the effectiveness of the learning process. Even though this topic has been the subject of substantial prior research, many have not been explored in the context of Korean textbooks as learning foreign languages. The method used in this study was qualitative using a multimodal discourse analysis. The data were analyzed using the image representation mode of Kress van Leeuwen (KvL). The data were collected from visual images showing cultural identities such as gender roles and ideology, contained in each chapter of the Korea Foundation Level 1 textbook, focused on the speaking (Malhagi) and cultural sections. The results of the data analysis show that cultural representation is dominated by Korean culture in both animated and non-animated images. However, the social role of people's lives represented in the picture corresponds to Indonesia and some pictures are found to be relevant to Indonesia, as the religion of the majority of Indonesians is depicted in the book. Almost all images are illustrated with animated visuals. Male gender is more heavily highlighted than female gender, rendering gender bias. This is related to the Confucian principles that exist in South Korea. Apart from the ulterior motives, the existence of Korean language learning textbooks for Indonesians provides benefits as a multimodal learning medium and helps teachers and students as a support medium for teaching and learning purposes. Keywords: Visual Language, Representation Mode, Multimodal Discourse, Culture
Two-Step Adaptive Target Detection Scheme Using Beam-Steering FMCW Radar Sensors
Authors: Kim Bong-seok , Jin Young-seok , Bae Jieun , Hyun Eugin
Published: December 2024

This letter proposes a two-stage adaptive target detection approach using a beam-steered frequency-modulated continuous wave (FMCW) radar sensor. In the first step, coarse estimation was performed using multiple sharped beams, where the presence of a target was determined using only a portion of the sampled beat signals. In the second step, a high-resolution range-Doppler (RD) map was generated using the entire information about the beat signal pertaining to the transmitted beams estimated to contain the target. Angle estimation was accomplished through digital beamforming based on the enhanced RD map. Furthermore, to verify the effectiveness of the proposed algorithm, high-resolution target detection experiments were conducted using a 24-GHz FMCW radar, while complexity reduction was evaluated in terms of the required memory size.
Tunable Absorptive Dual Notch Filters Using A Stub-Loaded Coupled Line with An Inductor
Authors: Cho Young-Ho , Park Cheolsoo , Yun Sang-Won
Published: December 2024

This paper presents tunable absorptive dual-notch filters using a stub-loaded coupled line with an inductor. The two-pole Butterworth filter function is modified to attain absorptive responses at a notch frequency. In addition, a stub-loaded coupled line with an inductor is employed to obtain dual-band bandstop responses, the required coupling coefficients, and quality factors based on the modified Butterworth function at two notch frequencies. In the proposed filter, tunable absorptive dual-notch responses are accomplished without using auxiliary circuits, such as an impedance matching network. The two resonant frequencies and the quality factors of the resonators are independently controlled by adjusting the three loading capacitances of the resonator. Three types of filters are designed and then built on a substrate with εr = 3.42 and h = 30 mils. The first filter (Filter A) attained a return loss of 11.2–17.1 dB/10.5–24.4 dB at 0.76–0.98 GHz/1.05–1.28 GHz. The measured return loss of the second filter (Filter B) was 12.5–14.8 dB/10.2–12.3 dB at 0.84–1.08 GHz/1.35–1.59 GHz. For Filter C, equipped with a 4-pole response achieved through the cascade connection of two 2-pole filters (Filter B), a return loss of 11.2–15.1 dB/14.2–27.3 dB was obtained at 0.9–1.1 GHz/1.38–1.63 GHz. The application areas of the proposed filters include cognitive radios and carrier aggregation systems requiring two transmit frequencies.

Authors: Huang Jing , Yoo Youngin , Jo Seung-Joo , Seo Chang-Won , Lee Si-A , Yoon Seong-Sik , Park Seong-Ook
Published: December 2024

Metallic mesh with complex woven structures is commonly used as the surface in large aperture spaceborne reflector antennas. To study the electrical properties of mesh surfaces characterized by intricate patterns, this paper presents a method for building models to analyze complex meshes. High Frequency Structure Simulator and Computer Simulation Technology (CST) simulation of the reflection coefficients, with Astrakhan’s formulation as a reference, confirm that applying the wire-grid model in CST using the tetrahedral mesh type provides sufficiently accurate results. Furthermore, the rectangular periodic wire-grid model is simulated in CST, and its results are compared with those of Astrakhan’s formulation. Correlations between reflection characteristics and influence factors, including mesh opening size, wire diameter, nature of wire contact, and wave incident angle, are investigated. To exemplify the applicability of the wire-grid model to complex mesh with irregular pattern shapes, the reflection coefficients of a warp-knitted gold-coated molybdenum mesh woven by multi-wires are measured and compared to the simulated results from the wire-grid model. The results prove that the method proposed in this paper is suitable for modeling metal mesh with complex weave patterns.
Determining Compensation Circuit Values to Minimize Leakage Magnetic Field in Wireless Power Transfer Systems with Double-Sided LCC Topology
Authors: Shin Yujun , Woo Seongho
Published: December 2024

This paper proposes compensation circuit values for minimizing the leakage magnetic field in wireless power transfer (WPT) systems with a double-sided LCC topology by identifying the resonant condition in which the vector sum of the coil currents of a WPT system is minimized. The proposed method for calculating compensation circuit values is obtained through mathematical derivation using arithmetic– geometric mean inequality and verified through simulation and experimentation. The experimental results obtained using the compensation circuit values determined by the proposed method confirm a reduction in the leakage magnetic field of the WPT system with a double-sided LCC topology by at least 8% and up to 43% compared to the system that does not use the proposed method.
Implementation of an Integrated LoRa and Dual-Band GNSS Antenna in a Compact Package
Authors: Kim Seongjung , Nam Sangwook
Published: December 2024

In this work, we propose an integrated long-range (LoRa; 0.92‒0.925 GHz) and global navigation satellite system (GNSS; 1.164‒1.189 GHz, 1.559‒1.609 GHz) antenna in a compact package, addressing the challenge of integrating antennas into highly size-limited applications. High radiation efficiency was achieved for the LoRa antenna by constructing a both-side-open-ended bent half-wavelength slot line, effectively preventing the cancelation of electric fields. Similarly, a compact configuration for the dual-band GNSS antenna was achieved using one-side-open-ended and quarter-wavelength slot lines. Finally, the LoRa and GNSS antennas were successfully integrated into a small printed circuit board. Furthermore, we introduce a method to measure the antenna while it is electrically connected to a control board and a battery while also evaluating its effects on operating frequencies. The simulated and experimental results demonstrated impedance bandwidths that cover the LoRa and GNSS bands, as well as the radiation efficiencies (64.9%, 46.3%, 54.2%) and radiation patterns of the proposed antenna. Overall, the proposed antenna exhibited compactness and radiation efficiency that surpassed other LoRa and GNSS antennas, even in the presence of unfavorable packaging effects.
Design and Optimization of Overlapping Multiple Coil with High Isolation Characteristics for Spatial Wireless Power Transfer Systems
Authors: Kwon Na-Rae , Ahn Seong-Hyeop , Lee Wang-Sang
Published: December 2024

The paper focuses on three-dimensional (3D) spatial wireless power transfer (WPT) and the challenges of improving the isolation between coils in a multiple-coil system. We analyze the mutual inductance between coils to derive an isolation method and propose a 3D overlapping multiple-coil system with high isolation for spatial WPT systems. Through performance verification, the proposed coils are verified to achieve approximately -20.1 dB isolation and an average power transfer efficiency of approximately 61.5%, even in the presence of angular or lateral misalignments of the receiving coil. This represents an improvement of approximately 41.7% over conventional multiple-coil systems. Therefore, it can be considered a viable solution to address the limitations of degraded power transfer efficiency in WPT systems designed for spatial freedom.

Results. The analysis of scientific approaches to transcendentalisation and subjectivisation in the study of values revealed stigmatised semantic meanings of the category “values” that do not correspond to modern scientific inquiries into the reasons for making losing decisions. Instead, in the bosom of psychology and against an interdisciplinary background, a research area related to the bio-psychological aspect of values is developing. This includes studies that focus on the dynamic, procedural nature of values. The latter makes it possible to study the disruption of the connection between the conscious and unconscious spheres, which results in mostly unconscious epiphenomena such as reality deformations, cognitive distortions, conditional values, uncontrolled actions, importation of the psyche, idealised “Self”, etc.
Conclusions. The modern semantic field of the category “values” is supplemented by new meanings related to the procedural nature of values at the bio-psychic level evaluation, acquisition of values, choice as an individual trajectory of life, creation of values, conventionality of values, correlation of conscious and unconscious spheres in the process of evaluation.  It is obvious that the new meanings of the semantic field of the category “values” have heuristic potential for solving urgent issues in decision-making practice.
THE IMPACT OF NEUROSCIENCE-BASED MINDFULNESS TRAINING ON MENTAL HEALTH IN FUTURE PSYCHOLOGISTS
Authors: Lazorko Olha
Published: December 2024

Purpose. This study investigates the effectiveness of a neuroscience-based mindfulness training program on emotional states, self-compassion traits and well-being status among psychology students during an 8-week intervention. The work focuses on developing emotional regulation, decreasing stress and depression, and increasing self-compassion and mindfulness — all of which are crucial skills for professional practice.
Methods. This pilot study included fifty psychology students (M = 23.5, SD = 2.8) who were assessed using the DASS-21 for stress, anxiety, depression and Self-Compassion Scale for self-kindness, mindfulness and related traits before and after a special training program along with the BBC-SWB questionnaire for psychological, physical and subjective well-being. Statistical analyses such as paired t-tests, correlation analysis and hierarchical regression were used to assess the intervention's effectiveness and explore predictive relationships among variables.
Results. The program was associated with significant reductions in anxiety, stress, and depression and increases in self-kindness, mindfulness, and psychological well-being. Given that emotional states and self-compassion traits function as mutually reinforcing factors, correlations provided evidence based on the holistic benefits of the program. Hierarchical regression analysis showed that both pre-intervention anxiety (β = 0.45, p < 0.001) and self-kindness (β = 0.35, p = 0.05) significantly predicted psychological well-being after the intervention. These variables combined explained 52% of the outcome variance (R² = 0.52, p < 0.001). Mindfulness explained an additional 17% variance beyond all other variables combined, affirming its role as a transformational variable within the model.
Conclusions. This mindfulness training, based on neuroscience principles and research findings, is designed to decrease psychological suffering and enhance psychological resilience and self-compassion. The results call for incorporating such training within psychology educational programs, thus enhancing personal health and professional competence. Longitudinal studies investigating the long-term effects of mindfulness practices and their use in a broader range of populations are warranted for future research.
Influencia de la Inteligencia Artificial en el ámbito educativo

Published: December 2024

Este estudio investiga los efectos de la inteligencia artificial en la eficiencia de la toma de decisiones, la propensión a la pereza y los problemas de privacidad entre los estudiantes universitarios de México. Aunque la educación, al igual que otros sectores, ha integrado tecnologías de IA para enfrentar desafíos contemporáneos, es alarmante que muchas investigaciones e instituciones a nivel mundial resalten únicamente los beneficios de la IA, omitiendo sus riesgos. Este estudio emplea el software PLS-Smart para analizar los datos recabados de 285 estudiantes de una universidad de negocios, seleccionados mediante muestreo intencional. Los hallazgos indican que la IA impacta significativamente en las decisiones humanas y contribuye a la pereza. Además, presenta riesgos para la seguridad y la privacidad, siendo la pereza el aspecto más afectado. La investigación argumenta la necesidad de adoptar medidas de precaución antes de implementar tecnología de IA en el sector educativo. Ignorar las preocupaciones fundamentales sobre la IA podría resultar perjudicial. Se aconseja prestar especial atención al diseño, implementación y uso ético de la IA en educación.
PEER VICTIMIZATION AND AGGRESSION AMONG SCHOOL STUDENTS
Authors: R Pushpalatha
Published: December 2024

Research around the world has shown that peer victimization is a common phenomenon among pupils in educational institutions. Peer victimization here refers to different forms of repeated physical or emotional harm directed towards a child. Physical harm could include hitting or punching, whereas emotional harm could include name-calling or being excluded from the peer group. Aggression is defined as a behaviour directed toward the goal of harming or injuring another living being, where the other person will be motivated to avoid the harm. Aggression is related to mental health problems in children, including externalizing disorders as Oppositional Defiant Disorder and Conduct Disorder, as well as internalizing problems with Depression and Anxiety. The belief that aggression is more of a problem of the industrialized nations is falling short of space as the developing ones are catching up with them.  Aggression not only spoils the school environment but also is a risk factor for future delinquency (UNESCO). The aim is to study peer victimization and aggression among school children. The sample consisted of 60 children of which 30 were boys and 30 were girls. The age of the students ranged between 10 to 16 years. All the students were residents of Bangalore city. The students were administered the multidimensional peer victimization scale-24 and the aggression scale. Prior consent from the school and parents was taken before administering the scales to children. The subjects were assured regarding the confidentiality of the data and that the collected data would be used for research purposes only. A purposive sampling design was opted for the study. The mean, SD and t were computed using appropriate statistical measure. The result showed that there was a significant gender difference in peer victimization and aggression
Comparison of asynchronous online versus in-person library instruction methods for teaching literature searching to graduate students

Published: December 2024

Introduction: The objectives of this comparative study were 1) to compare the effectiveness of in-person classroom instruction versus an online video for teaching literature searching skills to graduate students, and 2) to evaluate their perceptions of the instruction methods received and their instruction preferences for learning literature searching skills.
Methods: Students enrolled in a translational medicine graduate course in Fall 2022 were invited to participate in the study. Participants were randomly assigned to a control group (receiving in-person instruction) or to an intervention group (receiving a link to a narrated PowerPoint video). Using Qualtrics online survey tool, participants completed one pre-test and two post-tests to assess learning and retention, and a survey to evaluate their perceptions and attitudes.
Results: 12 out of 17 students participated. Both instruction methods were effective for delivering this information literacy content. The in-person group improved more than the online video group from pre- to post-test 1 and from pre- to post-test 2, but the difference was not statistically significant. However, the online video group rated the pace, perceived effectiveness, and clarity of library instruction, and their confidence to perform specific search tasks, more favourably than the in-person group, although the difference was not significant. Participants valued being able to access library training on their own schedule most of all.
Discussion: The sample size for this study was small, making it difficult for differences to attain statistical significance. Creating an online video to deliver this content ended up being very time-intensive compared to providing synchronous instruction.
Librarian involvement on knowledge synthesis articles and its relationship to citation counts and Journal Impact Factor
Authors: Alexander Krista , Hall Katharine , Chen Yuling Max
Published: December 2024

Introduction: Our aim was to determine if there is a relationship between librarian involvement on a knowledge synthesis project and the synthesis’s citation count or the Journal Impact Factor (JIF) of its publication venue.
Methods: A total of 551 knowledge syntheses published during a one-year period (2020) from a single category, “Psychology, Clinical”, in Clarivate’s Journal Citation Reports were exported from Web of Science along with the citation counts for each synthesis and the JIF of its publication venue. The full-text of each article was examined in order to code each as either co-author, acknowledged, or unknown to reflect the level of librarian involvement in the synthesis. The Wilcoxon Rank Sum test on bootstrapped samples was used to determine the significance of the results.
Results: Librarians were co-authors or acknowledged in 80 (15%) of the syntheses examined.  Analyzing two levels of librarian involvement (involved, unknown) indicated no relationship between the level of librarian involvement and the JIF of the journal nor the citation count the synthesis received since publication.
Discussion: There is no evidence of a relationship between librarian involvement in knowledge syntheses and the JIF of the publication or citation count of documents published in journals falling in the JCR category of “Psychology, Clinical” in the year 2020. Repeating this methodology in a different JCR category could help determine whether this lack of a relationship extends beyond the “Psychology, Clinical” category.
