Background

In recent years, virtual reality (VR) has gained significant importance in medical education. Radiology education also has seen the induction of VR technology. However, there is no comprehensive review in this specific area. This review aims to fill this knowledge gap.

Objective

This systematic literature review aims to explore the scope of VR use in radiology education.

Methods

A literature search was carried out using PubMed, Scopus, ScienceDirect, and Google Scholar for articles relating to the use of VR in radiology education, published from database inception to September 1, 2023. The identified articles were then subjected to a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)–defined study selection process.

Results

The database search identified 2503 nonduplicate articles. After PRISMA screening, 17 were included in the review for analysis, of which 3 (18%) were randomized controlled trials, 7 (41%) were randomized experimental trials, and 7 (41%) were cross-sectional studies. Of the 10 randomized trials, 3 (30%) had a low risk of bias, 5 (50%) showed some concerns, and 2 (20%) had a high risk of bias. Among the 7 cross-sectional studies, 2 (29%) scored “good” in the overall quality and the remaining 5 (71%) scored “fair.” VR was found to be significantly more effective than traditional methods of teaching in improving the radiographic and radiologic skills of students. The use of VR systems was found to improve the students’ skills in overall proficiency, patient positioning, equipment knowledge, equipment handling, and radiographic techniques. Student feedback was also reported in the included studies. The students generally provided positive feedback about the utility, ease of use, and satisfaction of VR systems, as well as their perceived positive impact on skill and knowledge acquisition.

Conclusions

The evidence from this review shows that the use of VR had significant benefit for students in various aspects of radiology education. However, the variable nature of the studies included in the review reduces the scope for a comprehensive recommendation of VR use in radiology education.

Authors: Parmanto Bambang , Aryoyudanta Bayu , Soekinto Timothius Wilbert , Setiawan I Made Agus , Wang Yuhan , Hu Haomin , Saptono Andi , Choi Yong Kyung
Published: May 2024

Background

In the United States, 1 in 5 adults currently serves as a family caregiver for an individual with a serious illness or disability. Unlike professional caregivers, family caregivers often assume this role without formal preparation or training. Thus, there is an urgent need to enhance the capacity of family caregivers to provide quality care. Leveraging technology as an educational tool or an adjunct to care is a promising approach that has the potential to enhance the learning and caregiving capabilities of family caregivers. Large language models (LLMs) can potentially be used as a foundation technology for supporting caregivers. An LLM can be categorized as a foundation model (FM), which is a large-scale model trained on a broad data set that can be adapted to a range of different domain tasks. Despite their potential, FMs have the critical weakness of “hallucination,” where the models generate information that can be misleading or inaccurate. Information reliability is essential when language models are deployed as front-line help tools for caregivers.

Objective

This study aimed to (1) develop a reliable caregiving language model (CaLM) by using FMs and a caregiving knowledge base, (2) develop an accessible CaLM using a small FM that requires fewer computing resources, and (3) evaluate the model’s performance compared with a large FM.

Methods

We developed a CaLM using the retrieval augmented generation (RAG) framework combined with FM fine-tuning for improving the quality of FM answers by grounding the model on a caregiving knowledge base. The key components of the CaLM are the caregiving knowledge base, a fine-tuned FM, and a retriever module. We used 2 small FMs as candidates for the foundation of the CaLM (LLaMA [large language model Meta AI] 2 and Falcon with 7 billion parameters) and adopted a large FM (GPT-3.5 with an estimated 175 billion parameters) as a benchmark. We developed the caregiving knowledge base by gathering various types of documents from the internet. We focused on caregivers of individuals with Alzheimer disease and related dementias. We evaluated the models’ performances using the benchmark metrics commonly used in evaluating language models and their reliability for providing accurate references with their answers.

Results

The RAG framework improved the performance of all FMs used in this study across all measures. As expected, the large FM performed better than the small FMs across all metrics. Interestingly, the small fine-tuned FMs with RAG performed significantly better than GPT 3.5 across all metrics. The fine-tuned LLaMA 2 with a small FM performed better than GPT 3.5 (even with RAG) in returning references with the answers.

Conclusions

The study shows that a reliable and accessible CaLM can be developed using small FMs with a knowledge base specific to the caregiving domain.

Centralized Pump Monitoring System: Perception on Utility and Workflows by Nurses in a Tertiary Hospital (Preprint)
Authors: Chindamorragot Naruemol , Suitthimeathegorn Orawan , Garg Amit
Published: May 2024

UNSTRUCTURED

Nurses play a key role in providing in-hospital care to patients. Worldwide, there has been a shortage of nursing staff, putting enormous strain on the existing nursing workforce physically and mentally. A vicious cycle of demanding workplaces exacerbated by perennial shortages leads to attrition and high staff turnover. A centralized, automated infusion pump monitoring system optimizes and augments nurses’ performance in the hospital by cutting down on nurse visits to the patient’s bedside for every matter, whether significant or insignificant. This viewpoint intends to highlight that by filtering out the noise effectively, nurses can focus on improving patient outcome–led interventions and enhancing the quality of care.
The Translation of Body-part Rhetoric in Romeo and Juliet: Take the Example of Facial Terms
Authors: Li Qingtao
Published: May 2024

In Shakespeare’s Romeo and Juliet, numerous references to the human body are intertwined with a rich array of rhetorical devices including personification, simile, metaphor, metonymy, and synecdoche. Metaphorical rhetoric is a hallmark of Shakespearean language, often used to depict sensory experiences, symbolize objects and emotions, and flesh out characters. However, due to cognitive disparities between Western and Chinese cultures, the same rhetorical themes may be expressed with different objects across cultures. As a result, translators must employ various strategies to bridge these gaps. This study aims to examine the cognitive differences underlying body-related rhetoric, particularly facial descriptions, in five different translations of Romeo and Juliet spanning different periods. The goal is to analyze the translation techniques and methodologies employed by translators to address these cultural disparities.

Published: May 2024

Methylmalonic acidemia (MMA) is an autosomal recessive metabolic disorder of organic acids that causes various symptoms attributed to the accumulation of methylmalonic acids. We report the general anesthetic management of a 7-year-old girl with MMA who underwent periodontal treatment prior to kidney transplantation. One of our anesthetic goals was to maintain appropriate metabolism perioperatively, so we minimized her fasting time as short as possible and administered specially adjusted milk with simple carbohydrates preoperatively to reduce catabolism and promote anabolism. Consultation and cooperation with the patient’s pediatrician were also essential, as was being prepared to appropriately manage perioperative emesis due to the minimized fasting time. This case demonstrates the importance of perioperative nutritional management for patients with MMA.

Authors: B* Amith
Published: May 2024

Solid lipid nanoparticles were prepared by using the solvent evaporation method. The prepared solid lipid nanoparticles of felodipine from different batches were weighed accurately and filled into appropriate-sized capsules for further evaluation. The prepared nanoformulation was tested in vitro for drug entrapment efficiency found to be 97-99% for the formulation with soya lecithin and glyceryl mono-stearate and percentage yield. The results of the in vitro drug release study for all formulations performed at gastric pH 1.2 indicated that the drug was released in an immediate manner within 60 minutes, which could be due to a burst effect or a faster rate of drug release due to smaller particle size SLN13 the concentration of Glycerol Monosterate- 576.522mg and Poloxamer 188. In vitro release data from standardised nanoformulations was fitted to various release kinetics models for the drug release mechanism. The optimised formulation demonstrated improved drug release and entrapment efficiency, and in vitro release data were fitted to various kinetic models to better understand the drug release mechanism. In vitro assay results were ranged between 76.5 to 96%, Zeta potential -40.75 ± 2.33 (mV) ± SD, entrapment efficiency 99.32. Accelerated stability studies for standardised nanoformulations were performed for 6 months in accordance with standard ICH guidelines, and no appreciable changes in the physical appearance, drug content, and in vitro drug release rates of the nanoformulations were observed. As a result of the study's evidence, it is concluded that felodipineloaded solid lipid nanoparticles are the best choice for hypertension.

Published: May 2024

The goal of the current study is to produce calves by implanting recipient cows with in vitro generated embryos. For in vitro maturation, slaughterhouse-driven cumulus-oocyte-complexes (COCs) with an even cytoplasm and at least three layers of compact cumulus cells were chosen (IVM). For the purpose of in vitro fertilization, capacitated fresh spermatozoa and presumed matured COCs were co-cultured for 18 to 20 hours (IVF). Cumulus cells were removed by carefully pipetting them into TL-HEPES. The zygotes spent three days in an in vitro culture (IVC) droplet. After this initial phase of culture, the 8–32 cell embryos were moved to IVC-II media, where they remained until Day 8 of development. On day 8, these embryos were transferred into recipient cows, with two embryos transferred to each of the five recipient cows. On day 60 of embryo transfer (ET), rectal palpation was used to assess pregnancy followed by ultrasonography on day 90. Out of five recipients, one cow delivered twine calves with a pregnancy rate of 20%. The calves were named Falguni and Chaitali. The duration of gestation was 277 days. Falguni weighed 12.87 kg at birth, whereas Chaitali weighed 18.59 kg. Falguni and Chaitali both showed typical growth patterns, with an average 254.77 g and 463.15 g/day. At a regular age, both heifer calves reach puberty and give birth. This research emphasizes the possibility that ovocytes from slaughterhouse ovaries can be used to produce healthy IVP calves, which would be a major step forward in Bangladesh’s fast expansion of high-yield dairy cattle.

Authors: БатановГаухман Михаил
Published: May 2024

Данная статья является четвертой частью научного проекта под общим названием «Геометризированная физика вакуума на основе Алгебры сигнатур». В первых трех статьях [1,2,3] были заложены основы Алгебры стигнатур и рассмотрены основные аспекты кинематики вакуумных слоев. В этой статье продолжается развитие математического аппарата предлагаемого проекта, в частности развивается динамика вакуумных слоев на основе Алгебры сигнатур. Развитие данного направления исследования (при упрощениях, относящихся к дифференциальной геометрии Римана) привело к возможности геометризированного представления полей электрической напряженности и магнитной индукции. Данный геометризированный математический аппарат позволяет интерпретировать электромагнитное поле как переплетение ускоренных и вращательных потоков смежных слоев вакуума. Предложенные динамические модели ускоренных движений и вращений вакуумных слоев могут послужить теоретическим основанием для развития «нулевых» (т.е. вакуумных) технологий.

Published: May 2024

Social forestry has become an integral part of Indonesia's efforts to balance economic development, conservation of natural resources, and the well-being of local communities. The Jokowi administration has made significant efforts to promote this initiative, including allocating 12.7 million hectares of state forest areas and recognizing it as an instrument to address tenure issues in forest areas through the Omnibus Law on Job Creation with getting support from various regulations by relevant ministries. However, social forestry support is needed down to the local government/regional levels (provincial, regency, and village levels). This study aims to analyze the local government’s support for implementing social forestry. We employ Social Network Analysis to identify local government entities and their relationships in implementation processes. Additionally, document analysis is used to assess the extent of local government support through their working documents. The study shows that local government support for the implementation is still limited, with its execution primarily concentrated within a few agencies. Social forestry has not yet fully become a strategy for achieving community well-being around forests, enhancing local economies, or protecting forest resources. Furthermore, stakeholders' understanding of social forestry, resource availability, and local government policies to support it remains limited. Improvements in these three aspects are necessary to ensure successful implementation at the regional levels.

Published: May 2024

The study of authoritarian leadership has undergone significant development, with researchers exploring its different dimensions and consequences. This leadership style, characterized by a top-down approach and centralized decision-making authority, has been extensively examined in psychology, organizational behavior, and management literature. Scholars have delved into the effects of authoritarian leadership on various aspects of organizations such as employee satisfaction, motivation levels, productivity rates, turnover rates, and team dynamics. The research landscape surrounding authoritarian leadership has witnessed a recent surge in interest as scholars strive to understand its intricate connections with different variables. The primary objective of this study is to conduct a comprehensive bibliometric analysis on authoritarian leadership, aiming to identify the key research areas, influential authors, prominent journals in the field, and citation patterns. To our knowledge, no bibliometric analysis on authoritarian leadership can be found in the Scopus database, highlighting the novelty of our research. Through a source-based examination of scholarly articles and their citations pertaining to authoritarian leadership, this analysis offers valuable insights into the current state of research in this domain. By focusing on publications from the past decade onwards, we aim to uncover trends and potential gaps within existing literature while also providing guidance for future research endeavors. Our research findings will provide valuable insights into the phenomenon of authoritarian leadership, contributing to a deeper understanding of its implications. By delving into this topic, we hope to pave the way for future studies and investigations in this field that can build upon our findings and expand knowledge even further.
Enhancing durability and sustainability in concrete with fibre-reinforced composites
Authors: Salmi Abdelatif
Published: May 2024

This paper presents a study focused on two pivotal innovations in the field of fibre-reinforced concrete (FRC) to significantly enhance its durability and sustainability in construction. First, our research investigates the application of advanced self-healing mechanisms in FRC. By embedding microcapsules containing healing agents within the concrete matrix, we achieved a remarkable reduction in crack propagation and improved structural integrity. Our results demonstrate that the self-healing FRC exhibited a 30% increase in compressive strength and a 40% reduction in crack width, leading to a longer service life for concrete structures. Second, we explore the integration of sustainable materials in FRC production. By incorporating locally sourced and recycled materials, we successfully reduced the environmental impact associated with FRC manufacturing. Our findings reveal a substantial reduction in carbon emissions, with a 25% decrease in the overall carbon footprint of FRC production. This innovation not only contributes to a greener construction industry but also aligns with sustainability goals and regulations. This research underscores the transformative potential of self-healing mechanisms and sustainable material integration in FRC, offering tangible results in terms of increased durability and reduced environmental impact. These innovations promise to reshape the construction landscape, aligning it with the principles of sustainability and long-term structural resilience.
Impacts of riverbed aggradation on groundwater regime in a lowland area
Authors: Bara Márta Koczka , Dulovičová Renáta , Velísková Yvetta , Farkas Csilla
Published: May 2024

In this study, the influence of riverbed silting on the groundwater regime in a lowland area was investigated. The study area is situated at the Rye Island (Žitný Ostrov) in Slovakia, along the Gabčíkovo – Topoľníky canal, which is part of the drainage-irrigation canal system constructed in this locality. The Rye Island is an area with very low slope (0.25 10–4) and good climatic conditions for aquatic vegetation, therefore the canals are influenced by intensive silting processes. The spatial and temporal patterns of surface water – groundwater exchange are significantly influenced by the thickness of riverbed sediments and their permeability. The aim of this study was to evaluate the thickness and hydraulic conductivity of bed sediments in the Gabčíkovo – Topoľníky canal and to examine their influence on the groundwater – surface water interaction in the area. The hydraulic conductivity of the sediments was assessed from undisturbed samples by the falling head method. The obtained data were used for numerical simulations of groundwater heads by the TRIWACO model for different drainage and infiltration resistance conditions in the area of interest. The results of this study can support the planning of canal maintenance.
Prediction of shear stress distribution in compound channel with smooth converging floodplains
Authors: Kaushik Vijay , Kumar Munendra
Published: May 2024

Climate change can have a profound impact on river flooding, leading to increased frequency and severity of floods. To mitigate these effects, it is crucial to focus on enhancing early warning systems and bolstering infrastructure resilience through improved forecasting. This proactive approach enables communities to better plan for and respond to flood events, thereby minimizing the adverse consequences of climate change on river floods. During river flooding, the channels often take on a compound nature, with varying geometries along the flow length. This complexity arises from construction and agricultural activities along the floodplains, resulting in converging, diverging, or skewed compound channels. Modelling the flow in these channels requires consideration of additional momentum transfer factors. In this study, machine learning techniques, including Gene Expression Programming (GEP), Artificial Neural Networks (ANN), and Support Vector Machines (SVM), were employed. The focus was on a compound channel with converging floodplains, predicting the shear force carried by the floodplains in terms of non-dimensional flow and hydraulic parameters. The findings indicate that the proposed ANN model outperformed GEP, SVM, and other established approaches in accurately predicting floodplain shear force. This research underscores the efficacy of utilizing machine learning techniques in the examination of river hydraulics.
Effect on the splenocyte function of weaned piglets induced by continuous lipopolysaccharide injections
Authors: Yang Tingyu , Zhao Guotong , Zhu Wenlu , Yu Wanting , Jiang Yijie , Zhou Yunxiao , Li Yong
Published: May 2024

Introduction

When piglets are exposed to pathogens for a long period, the immune system organs, among them the spleen, play a major role in combating the stress caused by those pathogens. In the present study, the effect on splenocyte function was investigated in a model of weaned piglets in which stress was induced by multiple low doses of lipopolysaccharide (LPS).

Material and Methods

Forty-eight 28-day-old piglets were divided into two groups: the LPS group and the control group. During the experimental period of thirteen days, the LPS group was intraperitoneally injected with LPS (100 μg/kg) once per day, and the control group was injected with the same volume of 0.9% sterile saline. On the 1st, 5th, 9th and 13th days, the piglets’ spleens were collected for isolating splenocytes. The proliferation ability of splenocytes was evaluated by the cell-counting-kit 8 method. Flow cytometry was used to detect cell cycle stage and apoptosis, and the nitric oxide level of cell supernatant was also tested.

Results

In the experimental group, the proliferation ability of splenocytes was enhanced, the proportion of cells in the G0/G1 phase was smaller, and cells were promoted to the S and G2/M phases. Meanwhile, apoptosis was suppressed and nitric oxide release upregulated. The results were significantly different between the LPS group and the control group on the 5th and 9th days.

Conclusion

The difference between the results of one group and those of the other suggest that after the 5th LPS injection, multiple low doses of LPS activated splenocytes and restored the number of splenocytes, which maintained and possibly enhanced the regulation of the immune function of the spleen.
‘The Iron Curtain did not dissolve very well’: Reflections on EU Citizenship from CEE peripheralised perspectives
Authors: Pates Rebecca
Published: May 2024

Peripheralisation is determined in socio ‑demographic, economic, political and identitarian factors. It is, many say, by definition, characterised by a willingness to migrate, in particular among the younger generations. European citizenship comes with the right to migrate – to relocate, to work and to be treated as equals in many respects to the local citizenry. In this research paper, I explicate the results of twenty interviews in six CEE countries with 7 th ‑graders who were asked what they thought of European citizenship. Those who knew what this is give widely divergent answers, but there are two dominant themes running through their perspectives: they do not feel great affection for the EU, and whilst willing to migrate, they do not appreciate the need to do so. Thus, they feel the EU does not live up to its promises to deliver equality for all Europeans. One explanation they give for this is that ‘the Iron Curtain did not dissolve very well’: the burden of history is acutely experienced.
Not in my House: EU-citizenship among East-Central European Citizens: Comparative Analyses
Authors: Pickel Gert , Pickel Susanne
Published: May 2024

The successes of right -wing populist parties in Central and Eastern Europe, as well as a repeated distancing from the European Union, raise the question of whether there is such a thing as European citizenship at all. Citizenship is not understood as formal nationality, but as a sense of belonging. This ties in with the considerations of political cultural research. This article uses representative surveys to address the question: What about European Citizenship in Central and Eastern Europe? The results show that the feeling of belonging to the European Union in Eastern and Central Europe is better than its reputation and not lower than in Western Europe. However, there are differences in the recognition of plurality between the majority (not all) of Eastern European states compared to the majority of Western European states. In particular, the integration of Muslims is more strongly rejected. The same applies to the social acceptance of homosexuality. This partly explains the success of right -wing populists in Central and Eastern Europe and marks a certain cultural difference, which is primarily directed against a wet model of democracy that is considered too open to plurality. In short: Central and Eastern Europeans also see themselves as Europeans and EU members, but their ideas of a European democracy differ from Western ideas – especially in peripheral regions.
US-Visegrad Realities in Biden’s World of Democracies
Authors: Rada Peter
Published: May 2024

The ‘liberal world order’ can be considered as an historic exception in the history of ‘realist anarchy’ of international relations. This exception is the result of many factors and it has been significantly influenced by the power of the United States. Thus, the agenda of the world order can be analysed in the context of American foreign policy. The place of Central Europe – and in the Visegrad countries – can be analysed in this frame. This approach elaborates the basis for further inquiries also of the Central European-American relations but here the goal is to understand the place of the Visegrad countries in the context of the American led liberal world order. The goal of this study is to theorise the world order, and to identify the role of the United States and the place of the Visegrad countries in it. Furthermore, the study tries to draw theoretic conclusions in the light of the ‘Biden doctrine’ – which is theoretically coherent with the liberal characteristic of the order – to the Visegrad-US relations.

Analiza varijabilnosti srčanog ritma je metod praćenja prirodnog procesa, koji može ukazati na potencijalne promene u disanju i krvnom pritisku, koje nastaju kao posledica stresa i/ili emocija. Cilj ovog rada je primena Poenkare plot metode na IBI signale (Inter bitne intervale - intervale između dva uzastopna perioda talasnog oblika krvnog pritiska) kako bi se iz dobijenih Poenkare plot dijagrama izvukli standardni parametri. Signali na kojima smo radili su snimljeni na dve grupe pacova: Wistar femininum (obične ženke pacova) i spontanohipertenzivne ženke (koje imaju veće sklonosti ka razvoju hipertenzije).
A study on the design and operation of a special Korean language education course to improve health literacy for female marriage immigrants: Focusing on special program at N-si Family Center
Authors:   The Research Society for the Korean Language Education, Kim Charmyee
Published: May 2024

This study examines the design and operation of special Korean language program to promote health literacy during the Korean language education course for female marriage immigrants at the N-si Family Center in Korea. And the purpose is to suggest ways to improve the program based on the results of pilot operation and pre- and post-evaluation. 'Special Korean language program related to health' is based on a demand survey conducted by Cho, Hajin and Kim, Charmyee (2023) and is designed to fit the framework of the Ministry of Gender Equality and Family's Marriage Immigrant Capacity Building Support Project. To measure changes in female marriage immigrants' self-health awareness and improvement in health literacy according to the program, pre- and post-evaluation was conducted using FLI-FMI and HLAS, tools that have been verified in previous studies. As a result of statistical analysis using SPSS29, FLI-FMI showed that there was a significant change in the difference and improvement in health literacy of female marriage immigrants in the 12th session of the curriculum, but HLAS showed that the education did not affect the learner's self-reported health literacy so it does not appear to have had a significant impact on changing perceptions. However, when comprehensively considering the number of participants and the content of the satisfaction survey, it is difficult to be certain of the effectiveness of learning based on simple statistical figures or to determine that there has been no change in learners' self-perception of health literacy. As a follow-up study, it will be necessary to supplement areas that are difficult to uncover through quantitative research alone through qualitative research using methods such as in-depth interviews or FGI. This study is meaningful in that it presents a practical curriculum to improve immigrants' health rights and health literacy and verifies its effectiveness, but it has the limitation that it is difficult to generalize the content. We hope that by using this study as basic research, various studies on improving health literacy will be conducted.
A study on the vocabulary used by college students
Authors:   The Research Society for the Korean Language Education, Lee Jung-Joo
Published: May 2024

The purpose of this study is to examine the characteristics of vocabulary used by college students by analyzing their writing using quantitative methods. The subject of analysis is 194 essays written by 101 college students. As a result of the analysis, there were 10,135 individual vocabularies and 80,732 total vocabularies.
The top 100 high-frequency words among college students' vocabulary were largely the same as the results of the three surveys compared. As a result of classifying college student vocabulary according to three meaning groups, ‘first person’ vocabulary was used the most when it came to ‘person’-related vocabulary. ‘Indicative words and connecting words’ were used at 2.7% and 0.6%, respectively, and were considered to have contributed to increasing the cohesion of the writing. Vocabulary related to ‘leisure life’ was used at a rate of 2.4% of the total vocabulary, and it was confirmed that vocabulary reflecting the growth background of current generation students appeared with high frequency.
The research results of this paper will help instructors understand their students. A limitation of this paper is that its analysis results do not apply to all college students. However, this limitation is seen as an inevitable limitation of vocabulary measurement research.
