Struktur Grup pada Pocket Cube
Authors: Kurniawan Prihadi
Published: April 2023

The objective of this research is to examine the abstraction of a semi-direct product group that originates from a specific object, which is the pocket cube. The process involves constructing groups by identifying free groups that are produced from reduced rotation sequences with finite standard rotations within the pocket cube. Moreover, by taking the action group to the position and orientation of the cubino on the pocket cube, the set of member pairs in S_8 and Z_3^8 is derived. The investigation then focuses on various valid random patterns on the pocket cube to determine how they correspond to each element in the semi-direct product of S_8 and Z_3^8. Additionally, the study describes the randomness of the pocket cube pattern when two reduced rotation sequences are applied sequentially by analyzing the operational representation of the semi-direct product group members.Keywords: group, pocket cube, semi-direct product.
Calibration of hydrological models for ungauged catchments by automatic clustering using a differential evolution algorithm: The Gorganrood river basin case study
Authors: Alizadeh Zahra , Yazdi Jafar
Published: April 2023

The hydrological model calibration is a challenging task, especially in ungauged catchments. The regionalization calibration methods can be used to estimate the parameters of the model in ungauged sub-catchments. In this article, the model of ungauged sub-catchments is calibrated by a regionalization approach based on automatic clustering. Under the clustering procedure, gauged and ungauged sub-catchments are grouped based on their physical characteristics and similarity. The optimal number of clusters is determined using an automatic differential evolution algorithm-based clustering. Considering obtained five clusters, the value of the silhouette measure is equal to 0.56, which is an acceptable value for goodness of clustering. The calibration process is conducted according to minimizing errors in simulated peak flow and total flow volume. The Storm Water Management Model is applied to calibrate a set of 53 sub-catchments in the Gorganrood river basin. Comparing graphically and statistically simulated and observed runoff values and also calculating the value of the silhouette coefficient demonstrate that the proposed methodology is a promising approach for hydrological model calibration in ungauged catchments.

Published: April 2023

Global climate models (GCMs) are the state-of-the-art tool for understanding climate change and predicting future. However, little research has been reported on the latest NEX-GDDP-CMIP6 product in China. The purpose of this study was to evaluate the simulated performance and drought capture utility of the NEX-GDDP-CMIP6 over China. First, the simulation skills of the 16 GCMs in NEX-GDDP-CMIP6 was evaluated by the 'DISO', a big data evaluation method. Second, the DISO framework for drought identification was constructed by coupling the Correlation Coefficient (CC), False Alarm Rate (FAR) and Probability of Detection (POD). Then, it was combined with SPI and SPEI to evaluate the drought detection capability of NEX-GDPD-CMIP6. The result shows that: (1) NEX-GDPD-CMIP6 can reproduce the spatial distribution pattern of historical precipitation and temperature, which performs well in simulating warming trend but fails to capture precipitation's fluctuation characteristics. (2) The best performing model in precipitation is ACCESS-CM2 (DISO 1.630) and in temperature is CESM2 (DISO 3.246). (3) The 16MME performs better than the best single model, indicating that multi-model ensemble can effectively reduce the uncertainty inherent in models. (4) The SPEI calculated by 16MME identifying drought well in arid, while SPI is recommended for other climate classifications of China.

Энергии ионизации Cu-подобных ионов с Z≤92
Authors: Иванова Е.П. , Панфилов В.А.
Published: April 2023

The overview of the experimental and theoretical data on the ionization energies (IE) of the Cu -like ions is presented. In various works data are obtained by interpolation and extrapolation the parameters of model potentials for Dirac equations. In other approaches, the function of the dependence of the ionization energy on Z (Z is nuclear charge) is approximated by a polynomial with power-law dependence on Z in order to achieve a minimum difference between theoretical and experimental data. The compilation of ionization energies is in database of the National Institute of Standards and Technology (USA), where the typical uncertainty is several units in the fourth significant digit. This means that for heavy ions the error can reach several tens of thousands cm–1. In this work, the ionization energies of Cu-like ions are refined to achieve accuracy to the fifth significant digit. Two methods have been developed for the interpolation and extrapolation. Scaling ionization energies along Z: scaling results in the function of the dependence of ionization energies on Z to the form of a quasi-line, i.e., weakly varying function on interval of 10−15 Z values. This allows the function to be interpolated up to the fifth significant numbers. The scaled refined function of the dependence of the ionization energy on Z is approximated by analytical functions that allow extrapolation with good accuracy to the Z~92 region. The relativistic model potential is used to interpolate and extrapolate ionization energies. The parameter of the relativistic model potential for the 4s1/2 orbital turned out to be almost linear function of Z for Z > 70, which made it possible to extrapolate with high accuracy to the Z region of 92. The results of both methods are in good agreement up to Z~ 92.

The absorption and luminescence spectra and the luminescence lifetime of the excited state 2F5/2 of Yb3+ ions in CCl4 – GaCl3 – Yb3+ solutions have been measured. Information was obtained on the Stark splitting of levels, on the absorption and stimulated emission cross sections, and on the quantum yield of Yb3+ luminescence. The spectral dependences of the gain cross section are calculated for different relative inverse populations of the 2F5/2 excited state. Based on an analysis of the spectral and laser properties of Yb3+, it was concluded that the use of CCl4 – GaCl3 – Yb3+ solutions as the active medium of a liquid ytterbium laser is promising.

Authors: Stone Haley , Heslop David , Lim Samsung , Sarmiento Ines , Kunasekaran Mohana , MacIntyre C Raina
Published: April 2023

Background

On February 25, 2022, Russian forces took control of the Chernobyl power plant after continuous fighting within the Chernobyl exclusion zone. Continual events occurred in the month of March, which raised the risk of potential contamination of previously uncontaminated areas and the potential for impacts on human and environmental health. The disruption of war has caused interruptions to normal preventive activities, and radiation monitoring sensors have been nonfunctional. Open-source intelligence can be informative when formal reporting and data are unavailable.

Objective

This paper aimed to demonstrate the value of open-source intelligence in Ukraine to identify signals of potential radiological events of health significance during the Ukrainian conflict.

Methods

Data were collected from search terminology for radiobiological events and acute radiation syndrome detection between February 1 and March 20, 2022, using 2 open-source intelligence (OSINT) systems, EPIWATCH and Epitweetr.

Results

Both EPIWATCH and Epitweetr identified signals of potential radiobiological events throughout Ukraine, particularly on March 4 in Kyiv, Bucha, and Chernobyl.

Conclusions

Open-source data can provide valuable intelligence and early warning about potential radiation hazards in conditions of war, where formal reporting and mitigation may be lacking, to enable timely emergency and public health responses.
An Investigation of Factors Influencing the Postponement of the Use of Distributed Research Networks in South Korea: Web-Based Users’ Survey Study
Authors: Rho Mi Jung , Park Jihwan
Published: April 2023

Background

Distributed research networks (DRNs) offer researchers the advantage of using various big data sets that are difficult to access and use. In addition, since the data are not physically exposed to the outside, it is possible to conduct research using medical data safely without data exposure. However, researchers still have difficulties and are concerned about using DRNs. Few studies involving DRNs have been conducted from the user’s viewpoint. Therefore, it is necessary to look at DRNs from the researcher’s point of view and find ways to facilitate the active use of DRNs.

Objective

This study aimed to identify the factors that made researchers hesitate to use DRNs and to derive a method to facilitate active DRN use.

Methods

We conducted a web-based survey of people working in the medical fields, such as hospitals and universities. We used 131 respondents’ data from a survey from December 6 to 17, 2021. We conducted multiple regression analyses to determine the factors affecting the postponement of using DRNs. In addition, 2 independent sample t tests were conducted to analyze the difference between the 2 groups according to the following factors: organization, gender, experience with DRNs, length of the research career, position, and age.

Results

Performance risk (t5=2.725, P=.007) and workload from DRNs (t5=3.543, P=.001) were significantly associated with users’ postponement of DRN use. Researchers working at hospitals were found to feel more burdened by DRN use than researchers working at universities (t129=1.975, P=.05). It was also found that women perceived a higher privacy risk of DRNs than men (t129=–2.303, P=.02) and that those who had experience using DRNs delayed their use less than those without experience (t129=–4.215, P<.001).

Conclusions

It is necessary to simplify the research and approval processes to reduce the performance risk and workload of research using DRNs. To optimize the process, DRN providers should develop a way to improve users’ experiences. More user-friendly functionalities should be developed from the researcher's point of view. It is necessary to continuously promote effective functionalities for DRNs to reduce concerns about privacy risks. This study identified the concerns of DRN users in terms of DRN use and suggested ways to actively use DRNs. The derived results can be reflected in planning and developing DRNs. Our research will be helpful to prepare an activation plan for DRNs.
Evolution of Health Information Sharing Between Health Care Organizations: Potential of Nonfungible Tokens
Authors: Esmaeilzadeh Pouyan
Published: April 2023

This study attempts to explain the development and progress of the technology used for sharing health information across health care organizations (such as hospitals and physicians’ offices). First, we describe the strengths and weaknesses of traditional sharing models, health information exchange (HIE), and blockchain-based HIE. Second, the potential use of nonfungible token (NFT) protocols in HIE models is proposed as the next possible move for information-sharing initiatives in health care. In addition to some potential opportunities and distinguishing features (eg, ownability, verifiability, and incentivization), we identify the uncertainty and risks associated with the application of NFTs, such as the lack of a dedicated regulatory framework for legal ownership of digital patient data. This paper is among the first to discuss the potential of NFTs in health care. The use of NFTs in HIE networks could generate a new stream of research for future studies. This study provides practical insights into how the technological foundations of information-sharing efforts in health care have developed and diversified from earlier forms.
Developing a Digital Medication Adherence Intervention for and With Patients With Asthma and Low Health Literacy: Protocol for a Participatory Design Approach (Preprint)
Authors: Faber Jasper S , Poot Charlotte C , Dekkers Tessa , Romero Herrera Natalia , Chavannes Niels H , Meijer Eline , Visch V T
Published: April 2023

BACKGROUND

Current eHealth interventions are poorly adopted by people with low health literacy (LHL) as they often fail to meet their needs, skills, and preferences. A major reason for this poor adoption is the generic, one-size-fits-all approach taken by designers of these interventions, without addressing the needs, skills, and preferences of disadvantaged groups. Participatory design approaches are effective for developing interventions that fit the needs of specific target groups; yet, very little is known about the practical implications of executing a participatory design project for and with people with LHL.

OBJECTIVE

This study aimed to demonstrate the application of participatory design activities specifically selected to fit the needs and skills of people with LHL and how these were manifested within an overarching eHealth design process. In addition, the study aims to present reflections and implications of these activities that could support future designers to engage people with LHL in their design processes.

METHODS

We used the design process of a smart asthma inhaler for people with asthma and LHL to demonstrate participatory design activities. The study was framed under 5 stages of design thinking: empathize, define, ideate, prototype, and test within 2 major iteration cycles. We integrated 3 participatory design activities deemed specifically appropriate for people with LHL: co-constructing stories, experience prototype exhibition, and video prototype evaluation.

RESULTS

Co-constructing stories was found to deepen the understanding of the participant’s motivation to use or not to use maintenance medication. This understanding informed and facilitated the subsequent development of diverse preliminary prototypes of possible interventions. Discussing these prototypes in the experience prototype exhibition helped provoke reactions, thoughts, and feelings about the interventions, and potential scenarios of use. Through the video prototype evaluation, we were able to clearly communicate the goal and functionality of the final version of our intervention and gather appropriate responses from our participants.

CONCLUSIONS

This study demonstrates a participatory design approach for and with patients with asthma and LHL. We demonstrated that careful consideration and selection of activities can result in participants that are engaged and feel understood. This paper provides insight into the practical implications of participatory activities with people with LHL and supports and inspires future designers to engage with this disadvantaged target group.

CLINICALTRIAL
Investigating the Role of Upward Comparisons and Self-compassion on Stigma in People With Acne: Cross-sectional Study (Preprint)
Authors: Adkins Kate , Overton Paul G , Moses Julia , Thompson Andrew
Published: April 2023

BACKGROUND

The use of image-laden social media is hypothesized as being implicated in psychological distress in individuals with conditions affecting their appearance. However, relatively little is known about the mechanisms involved in this relationship.

OBJECTIVE

This cross-sectional study examined the relationship between photo-orientated social media use and feelings of stigmatization in adults with acne, and tested whether upward skin comparisons mediate and self-compassion moderates this relationship.

METHODS

Adults (N=650) with acne symptoms completed web-based measures of social media use (daily Facebook or Instagram use, Facebook function use), self-compassion, skin appearance comparisons, and internalized stigmatization.

RESULTS

Moderated-mediation and mediation analyses indicated that there was a significant indirect effect of Facebook photo use on stigmatization, mediated by upward appearance comparisons (estimation of indirect effect 11.03, SE 5.11, 95% CI 1.19-21.12). There was no significant relationship between Instagram use and feelings of stigmatization (estimation of indirect effect 0.0002, SE 0.005, 95% CI −0.011 to 0.009), yet upward appearance comparisons predicted feelings of stigmatization (B=0.99, P<.001). Self-compassion did not moderate the indirect or direct relationships between photo-orientated social media use and stigma. However, self-compassion was negatively correlated with upward appearance comparisons and feelings of stigmatization in both Facebook and Instagram users.

CONCLUSIONS

The way that individuals engage with social media, and in particular make appearance comparisons, should be considered when working with individuals with skin-related distress. Interventions aimed at boosting self-compassion and reducing appearance comparisons may provide avenues for protecting against feelings of stigma.

BACKGROUND

The detrimental effects of the COVID-19 global pandemic have significantly changed the world's view on enacting policies. Egypt has adopted various protocols and measures to control the spread of its causative virus, SARS-CoV-2.

OBJECTIVE

This study aims to examine the public trust in decision-makers and help address possible gaps between the sources of information, theoretical guidelines, implementation, and the confidence of youth in response to the pandemic by the main actors involved.

METHODS

An online structured cross-sectional survey was conducted among Egyptian youth during the early COVID-19 pandemic. The questionnaire collected variables, including socio-demographic characteristics, sources of information, and the respondent's confidence in these sources.

RESULTS

Out of 406 online respondents, males and females were equally represented, 41.8% and 58.6%, respectively. Ninety-five percent of the respondents received a university or postgraduate education, of which 63.5% were in the medical field, and 82.3% lived in rural areas. Over forty percent reported their source of information was T.V., and 30.3% relied on social media, despite most of the respondents being unconfident in both. In addition, 12.8% and 5.9%reported their source of information was the Ministry of Health and the WHO, respectively. Over seventy-seven percent of the respondents were concerned with the decisions taken by key actors in the pandemic situation, while 15% were neutral, and 5.4% were not concerned.

CONCLUSIONS

Infodemics is a substantial public health threat. Public health authorities and governments should take action to ensure comprehensive health information literacy and develop information technology strategies that promote access to evidence-based information.

RESULTS

The incidence rate of depression in SCI patients was 87.3 per 1,000 person-years and aHR was 2.88 (95% CI 2.69−3.08) compared to the control group. Severe disability and cervical SCI increased the risk of depression (aHR 5.09, 95% CI 4.34−5.97; aHR 3.99, 95% CI 3.51−4.53, respectively). The incidence rate of depression was especially high within the first year after SCI. Male sex and young age were independent of risk factors for depression.

CONCLUSIONS

This present study suggest that depression is highly prevalent with SCI, especially patients with severe disability and cervical SCI. Physicians should monitor the occurrence of depression in patients with SCI, especially within one year after SCI.
Effect of Benign Biopsy Findings on an Artificial Intelligence–Based Cancer Detector in Screening Mammography: Retrospective Case-Control Study (Preprint)
Authors: Zouzos Athanasios , Milovanovic Aleksandra , Dembrower Karin , Strand Fredrik
Published: April 2023

BACKGROUND

Artificial intelligence (AI)–based cancer detectors (CAD) for mammography are starting to be used for breast cancer screening in radiology departments. It is important to understand how AI CAD systems react to benign lesions, especially those that have been subjected to biopsy.

OBJECTIVE

Our goal was to corroborate the hypothesis that women with previous benign biopsy and cytology assessments would subsequently present increased AI CAD abnormality scores even though they remained healthy.

METHODS

This is a retrospective study applying a commercial AI CAD system (Insight MMG, version 1.1.4.3; Lunit Inc) to a cancer-enriched mammography screening data set of 10,889 women (median age 56, range 40-74 years). The AI CAD generated a continuous prediction score for tumor suspicion between 0.00 and 1.00, where 1.00 represented the highest level of suspicion. A binary read (flagged or not flagged) was defined on the basis of a predetermined cutoff threshold (0.40). The flagged median and proportion of AI scores were calculated for women who were healthy, those who had a benign biopsy finding, and those who were diagnosed with breast cancer. For women with a benign biopsy finding, the interval between mammography and the biopsy was used for stratification of AI scores. The effect of increasing age was examined using subgroup analysis and regression modeling.

RESULTS

Of a total of 10,889 women, 234 had a benign biopsy finding before or after screening. The proportions of flagged healthy women were 3.5%, 11%, and 84% for healthy women without a benign biopsy finding, those with a benign biopsy finding, and women with breast cancer, respectively (P<.001). For the 8307 women with complete information, radiologist 1, radiologist 2, and the AI CAD system flagged 8.5%, 6.8%, and 8.5% of examinations of women who had a prior benign biopsy finding. The AI score correlated only with increasing age of the women in the cancer group (P=.01).

CONCLUSIONS

Compared to healthy women without a biopsy, the examined AI CAD system flagged a much larger proportion of women who had or would have a benign biopsy finding based on a radiologist’s decision. However, the flagging rate was not higher than that for radiologists. Further research should be focused on training the AI CAD system taking prior biopsy information into account.

Rural cooperatives as a small member-owned organizations are the potential to facilitate socio-economic development in rural areas. This study presents a novel hybrid method to develop strategies for development of rural cooperatives. It combines SWOT analysis, TOWS strategic alternatives matrix, and the analytic network process (ANP). SWOT was used to analyze the external and internal environment of rural cooperatives in Iran using the contributions of a team of experts. This team identified 19 SWOT sub-factors. A TOWS matrix was then constructed and the internal and external environmental sub-factors were combined to create good strategic alternatives. The expert team used the TOWS matrix to identify 11 strategic alternatives. ANP was applied to prioritize the strategic alternatives. According to the experts’ team, the presented combined approach helps managers to choose the best alternative strategies considering both internal and environmental factors.
Cambio climático para mí, para ti, para todas, todos, todes

Published: April 2023

El cambio climático ya nos alcanzó, como lo muestra indudablemente el último reporte de El Grupo Intergubernamental de Expertos sobre el Cambio Climático (el famoso ipcc). Estamos experimentando un incuestionable aumento térmico planetario, debido a la constante emisión de gases de efecto invernadero ligada a las actividades humanas. Junto con ello se acompañan cambios en la precipitación, en los extremos climáticos (como las sequías, las inundaciones y los huracanes) y en la estacionalidad dentro del año. Los impactos que esto trae y traerá son muchos, pero con eso también las oportunidades para generar una nueva forma de relacionarnos con la naturaleza y nuestro mundo. En este número especial de la Revista Digital Universitaria abordamos el tema del cambio climático moderno desde muchas perspectivas.

Las sociedades científicas estudiantiles y los semilleros de investigación, definiciones, objetivos, roles y organización
Authors: Castro-Rodríguez Yuri
Published: April 2023

Las experiencias investigativas desde el pregrado permiten al estudiante familiarizarse con los procesos de la investigación científica, además de formar sus competencias investigativas básicas. Las estrategias para lograr estos objetivos incluyen clubes de lectura crítica, seminarios investigativos, programas de investigadores jóvenes, participación en concursos, semilleros de investigación (SI), grupos de investigación y sociedades científicas de estudiantes (SCE). Los SI y las SCE son estrategias en las cuales el estudiante adquiere un rol protagónico en su proceso formativo; existe la discrepancia si ambos grupos presentan similitudes o diferencias, motivo por el cual se realiza el presente ensayo para plantear un marco de referencia de sus definiciones, objetivos, organización y roles. Las SCE y los SI son grupos estudiantiles interesados en la formación investigativa desde el pregrado. Algunas similitudes se encuentran en sus objetivos formativos y el rol de los estudiantes; de esta forma ambos buscan la formación de competencias, los SI se enfocan en las competencias investigativas, mientras que las SCE buscan formar competencias investigativas, comunicativas, interpersonales, asistenciales y de liderazgo. El rol central en una SCE lo tienen los estudiantes, el apoyo de docentes como asesores es opcional; a diferencia de un SI en el cual la presencia de un docente coordinador es mandatorio. Las SCE son un fenómeno frecuente en los programas de las ciencias de la salud (principalmente en el contexto latinoamericano), los SI se presentan en múltiples campos, existiendo la oportunidad de realizar trabajos interdisciplinarios.
