ABSTRACT

To optimize the current college sports data information management system, this study combines the Apriori association rule algorithm with web application development technology to upgrade the management system. Firstly, this study explores novel log mining techniques in genetic algorithms and web application development technology. Secondly, by integrating log mining techniques to optimize the Apriori algorithm, associations between sports data and information are discovered. Through the optimized algorithm, this study identifies key association rules of sports data information and validates the optimized system's reliability and effectiveness through experiments. The experimental results show that the running time of the traditional Apriori algorithm exponentially grows with the increase in information volume, while the optimized execution efficiency is improved by approximately 10-15%. Additionally, the average retrieval accuracy of this optimized system can reach 98.3%, although the retrieval time also increased by 23%. Therefore, the technology and algorithms proposed in this study have certain application value in the sports information management system and contribute to the optimization of data information management in this field.

ABSTRACT

Health information management is a vital and constructive component of the health system, refers to the process of producing and collecting, organising and storing, analysing, disseminating and using information. The aim of this study was to evaluate the strengths and weaknesses of the information management system in epidemic infectious diseases in Iran, specifically focusing on the registration, reporting, quality, confidentiality, and security of infectious disease data. This assessment was conducted from the perspective of policymakers and experts responsible for data registration and reporting. After examining the processes of registering and reporting infectious disease data and interviewing experts, a researcher-designed questionnaire was prepared to evaluate the infectious disease information management system. To assess the content validity of the Content Validity Index and Content Validity Ratio Index, a questionnaire was utilized. The reliability of the questionnaire was confirmed using Cronbach's alpha. By employing purposeful sampling and adhering to the inclusion criteria, 150 participants were included in the study. Questionnaires were distributed via email, WhatsApp, or Telegram to employees at various levels of Iran's health and treatment systems who were responsible for registering and reporting infectious disease data. The study encompassed 100 participants who successfully concluded the research. The results highlight that the key strength of healthcare data registration lies in its ability to "depict the epidemic curve during outbreaks of infectious diseases." Conversely, a notable weakness was the "insufficient collaboration from non-academic sectors (e.g., clinics, private laboratories) in registering and reporting infectious diseases. The present study's findings suggest that the issue lies not in the framework itself, but rather in the execution and functionality of the strategies. We can cultivate a repository of reliable and beneficial data by incorporating initiatives like training programs, enforcing regulations with consequences for inadequate data documentation, offering both material and motivational rewards, and streamlining all data collection and reporting systems.

ABSTRACT

Introducción: La oftalmología es la ciencia de la medicina que se encarga del estudio del sistema visual y el órgano de la visión, así como de sus anexos. Para ello es dotada de un conjunto de tecnologías de avanzada que permite describir las múltiples patologías que tienen los pacientes. En la actualidad se nutre del uso de los dispositivos móviles, fundamentalmente en la gestión del conocimiento, pero no se explotan sus otras dimensiones. Objetivo: Identificar los referentes que fundamentan el uso de la telefonía móvil en el proceso de enseñanza aprendizaje del residente de oftalmología. Métodos: Se realizó una investigación de desarrollo tecnológico en el campo de la educación médica superior. Se utilizaron como métodos teóricos el histórico-lógico, el analítico-sintético y el método sistémico estructural funcional. Resultados: La telefonía móvil constituye una nueva tendencia en la educación superior cubana y en la educación médica como alternativa para desarrollar los procesos de enseñanza aprendizaje, a través de su uso para la socialización, la comunicación entre los estudiantes, y la gestión de la información, como medio de enseñanza aprendizaje y herramienta de trabajo. Conclusiones: Existe una contradicción entre la formación que deben tener los residentes en oftalmología en cuanto al uso de las tecnologías, y la preparación que poseen para su utilización en función de su especialidad. A pesar de que existen varios estudios que demuestran la importancia del uso de la telefonía móvil en la formación de los residentes de oftalmología, como objeto de estudio y herramienta de trabajo, no se ha establecido la vía para incluirla como una de las tecnologías dentro de la residencia de oftalmología en Cuba(AU)


Introduction: Ophthalmology is the medical science dealing with the study of the visual system and the organ of vision, as well as its annexes. For this purpose, it is equipped with a set of advanced technologies that allow describing the multiple pathologies presented by patients. Nowadays, it is nourished by the use of mobile devices, mainly in knowledge management, but its other dimensions are not exploited. Objective: To identify the references that support the use of mobile telephony in the teaching-learning process of ophthalmology residents. Methods: A technological development research was carried out in the field of higher medical education. As theoretical methods, the historical-logical, the analytical-synthetic, and the systemic-structural-functional methods were used. Results: Mobile telephony is a new trend in Cuban higher education, as well as in medical education, as an alternative to develop teaching-learning processes, through its use for socialization, communication among students, and information management, as a teaching-learning means and a work tool. Conclusions: There is some contradiction between the training that ophthalmology residents should receive with respect to the use of technologies and the preparation that they have for their usage in accordance with their specialty. Although there are several studies that demonstrate the importance of using mobile telephony in the training of ophthalmology residents, as an object for studying and a work tool, there has not been a way to include it as one of the technologies within the ophthalmology residency in Cuba(AU)

ABSTRACT

En Cuba se ha identificado la necesidad de dominar y de introducir en la práctica las tecnologías de la información y las comunicaciones y de lograr una cultura digital como una de las características imprescindibles para los hospitales, lo cual sigue constituyendo un reto con múltiples aristas, enfoques y puntos de vistas. En este sentido se destaca el control interno como un motor de gestión de la información. Este trabajo tuvo como objetivo desarrollar un sistema informático para la automatización del cuadro de mando integral como herramienta de control interno en entidades hospitalarias, que contribuya a la gestión de la información en ciencias de la salud. Se programó un software mediante el entorno de desarrollo integrado Embarcadero Delphi, el cual utilizó Object Pascal como lenguaje de programación. Para el proceso de elaboración del sistema informático se empleó la metodología SCRUM, con una la lista de productos que consiste en el conjunto de requerimientos funcionales y no funcionales que debe satisfacer la aplicación. Se logró el desarrollo del software MULTI-CONTROL-INTERNO, con una ventana principal que incluye un menú contextual para acceder a todas las ventanas de la aplicación e introducir los valores de las variables necesarias para calcular los indicadores y gráficos dinámicos de cada una de las perspectivas del cuadro de mando integral, y se obtuvo el diseño de las estrategias para la mejora del sistema sanitario según la gestión de la información en el hospital a través de los índices de cumplimiento de los objetivos, la eficacia, la eficiencia y los componentes del control interno. El sistema informativo en entidades hospitalarias cubanas es hoy un acápite pendiente por la dinámica del entorno sanitario(AU)


The purpose of the study was to develop an information system for the automation of the integrated control panel as an internal control tool in hospitals, thus contributing to health information management. A software application was programmed in the Embarcadero Delphi integrated development environment, using Object Pascal as programming language. Development of the information system was based on SCRUM methodology, with a list of products consisting in the set of functional and non-functional requirements to be met by the application. The software Multi-internal-control was thus developed, with a main window which includes a context menu to access all the windows in the application and enter the values of variables required to estimate the dynamic charts and indicators of each of the perspectives on the integrated control panel, obtaining the design of strategies for the improvement of the healthcare system according to the information management procedure in place at the hospital, through goal achievement indices, efficacy, efficiency and internal control components. The information system at Cuban hospital institutions is still a pending item due to the dynamics of the healthcare environment(AU)

ABSTRACT

El objetivo de esta investigación fue identificar las necesidades de información sobre medicamentos y salud pública en los médicos de un hospital mexicano. Se realizó un estudio descriptivo y transversal mediante una encuesta validada por expertos y por estudio piloto a 112 médicos en el año 2016. Los participantes fueron seleccionados por muestreo aleatorio simple de un hospital público de segundo nivel en Nayarit, México. Las variables estudiadas fueron: necesidades de información, comportamiento informativo y el nivel de satisfacción. El 66,4 por ciento de los médicos necesitaban información relacionada con el tratamiento farmacológico de sus pacientes y el 63,3 por ciento de los médicos tuvo necesidades sobre datos poblacionales. Las revistas médicas fueron la vía preferida para obtener información (70,4 por ciento) y al mismo tiempo obtuvieron la puntuación más alta de satisfacción. El 89,5 por ciento no consultaba bases de datos o repositorios, y el motivo más común para no hacerlo fue por carecer de computadora e Internet en el lugar de trabajo (62,4 por ciento). El 76,8 por ciento consideró que sus necesidades de información estaban insatisfechas con los recursos y servicios proporcionados por el hospital. El estado actual de la gestión de la información de los médicos entrevistados pone en riesgo su actualización profesional, disminuye la posibilidad de prescribir tratamientos racionales y de tomar decisiones eficientes(AU)


The purpose of the study was to identify the information needs about drugs and public health among doctors from a Mexican hospital. A descriptive cross-sectional analysis was conducted in the year 2016 which was based on an expert validated survey and a pilot study of 112 doctors. Participants were selected by simple random sampling at a secondary hospital in Nayarit, Mexico. The variables analyzed were information needs, information behavior and satisfaction level. Of the doctors surveyed, 66.4 percent needed information related to the drug treatment of their patients, whereas 63.3 percent needed population data. Medical journals were the favorite source of information (70.4 percent) and obtained the highest satisfaction score. 89.5 percent of respondents did not consult any database or repository, and the most common reason was they did not have a computer with Internet access at the workplace (62.4 percent). 76.8 percent considered that their information needs were not satisfied by the resources and services available at the hospital. The current information management status of the doctors interviewed poses a risk to their professional updating, reducing the possibility of prescribing rational treatments and taking efficient decisions(AU)

ABSTRACT

Global misinformation and information overload have characterized the coronavirus disease (COVID-19) pandemic. Rumors are unverified pieces of information spreading online or person-to-person that reduce trust in health authorities and create barriers to protective practices. Risk communication and community engagement can increase transparency, build trust, and stop the spread of rumors. Building on previous work on Ebola and Zika viruses using Global Health Security Agenda systems strengthening support, the U.S. Agency for International Development-funded Breakthrough ACTION project developed a process and technology for systematically collecting, analyzing, and addressing COVID-19 rumors in real-time in Côte d'Ivoire. Rumors were submitted through community-based contributors and collected from callers to the national hotlines and then processed on a cloud-hosted database built on the open-source software District Health Information System 2 (DHIS2). Hotline teleoperators and data managers coded rumors in near-real-time according to behavioral theory frameworks within DHIS2 and visualized the findings on custom dashboards. The analysis and response were done in full collaboration with the Government of Côte d'Ivoire and implementing partners to ensure a timely and coordinated response. The system captured both widespread rumors consistent with misinformation in other settings, such as suspicions about case counts and the belief that masks were deliberately contaminated, as well as very localized beliefs related to specific influencers. The qualitative findings provided rapid insights on circulating beliefs, enabling risk communicators to nuance and tailor messaging around COVID-19.

ABSTRACT

This dissertation study investigates the ways that NHS libraries are currently marketing their services within their organisation and was submitted as part of the MA Library and Information Management at the University of Sheffield in 2019. This paper presents the findings from twelve semi-structured interviews carried out with NHS library managers in the East of England to identify the most and least successful methods, and in comparison with that which is currently in the general marketing literature. The study found that outreach marketing was the most effective and that librarians are currently conducting marketing to the best of their ability, but they lack time and funding to be able to make the most of their promotional campaigns.

ABSTRACT

OBJECTIVES: The aim of this study is to propose an approach for developing trustworthy recommendations as part of urgent responses (1-2 week) in the clinical, public health, and health systems fields. STUDY DESIGN AND SETTING: We conducted a review of the literature, outlined a draft approach, refined the concept through iterative discussions, a workshop by the Grading of Recommendations Assessment, Development and Evaluation Rapid Guidelines project group, and obtained feedback from the larger Grading of Recommendations Assessment, Development and Evaluation working group. RESULTS: A request for developing recommendations within 2 week is the usual trigger for an urgent response. Although the approach builds on the general principles of trustworthy guideline development, we highlight the following steps: (1) assess the level of urgency; (2) assess feasibility; (3) set up the organizational logistics; (4) specify the question(s); (5) collect the information needed; (6) assess the adequacy of identified information; (7) develop the recommendations using one of the 4 potential approaches: adopt existing recommendations, adapt existing recommendations, develop new recommendations using existing adequate systematic review, or develop new recommendations using expert panel input; and (8) consider an updating plan. CONCLUSION: An urgent response for developing recommendations requires building a cohesive, skilled, and highly motivated multidisciplinary team with the necessary clinical, scientific, and methodological expertise; adapting to shifting needs; complying with the principles of transparency; and properly managing conflicts of interest.

ABSTRACT

INTRODUCTION: Although the use of Reference Management Software (RMS) is increasing in developed countries, they seem to be unknown and less used in low-income countries. AIM: To discover the major trends in the use of RMS among researchers and Ph.D. students in Tunisia, as a low-income country. METHODS: A hardcopy survey was filled out by researchers and Ph.D. students during an educational seminar at the faculty of medicine of Sfax in 2016 with the aim to collect qualitative data to determine the participants' knowledge and use of RMS. RESULTS: The survey collected 121 participants, among them, 53.7% know RMS. Mendeley proved to be the best-known software (41.5%), followed by Zotero (35.3%) and Endnote (23%). Training sessions in RMS were taken by 5% of participants. Among the 121 participants, 26.5%of them use RMS., Mendeley was the most used (46.9%), followed by EndNote (28.1%) and Zotero (25%). The most commonly popular feature in RMS is inserting citations (66.9%). Therefore, the analysis, of the reasons behind the choice of RMS proves that the software was used because it is convenient (38.4%),  most known (38.4%),  easy (30.7%), or suggested by colleagues (30.7%). The free and open-source software was preferred by 81% of the participants. g. However, 50.4% ignore the fact that Zotero is free. Several types and sources of captured citations were unknown by 53.8% and 59% of the rest of the participants. CONCLUSION: The results clearly show that the lack of awareness about RMS in Tunisia is due to the absence of a formal training. As a result, the need for such training is highly important for researchers to be able to benefit from the different advantages of RMS while conducting their academic medical education.

ABSTRACT

OBJECTIVE: To investigate the application of mind mapping-based health education in extended care for children with caries. METHODS: This was a prospective study of 159 eligible children with caries. Participants were randomly assigned to an observation group and a control group, and received extended health education and guidance. Patients in the observation group received health education with mind mapping. In the third month after the first visit, a questionnaire survey was conducted to assess knowledge of extended caries diagnosis and treatment in children and their parents. Children also underwent a bacterial plaque test. RESULTS: Caries knowledge was significantly greater in the observation group than in the control group. There was no significant between-group difference in debris index on the bacterial plaque test. The observation group had a significantly greater number of follow-up visits in 12 months than the control group. CONCLUSIONS: Mind mapping was effective in the implementation of extended care. Mind mapping information was more accessible to children and their parents, increasing their compliance with health education. Thus, mind mapping is an appropriate health education tool for use in extended care for children with caries.

ABSTRACT

Although it is one of the most widely used methods in recommender systems, Collaborative Filtering (CF) still has difficulties in modeling non-linear user-item interactions. Complementary to this, recently developed deep generative model variants (e.g., Variational Autoencoder (VAE)) allowing Bayesian inference and approximation of the variational posterior distributions in these models, have achieved promising performance improvement in many areas. However, the choices of variation distribution - e.g., the popular diagonal-covariance Gaussians - are insufficient to recover the true distributions, often resulting in biased maximum likelihood estimates of the model parameters. Aiming at more tractable and expressive variational families, in this work we extend the flow-based generative model to CF for modeling implicit feedbacks. We present the Collaborative Autoregressive Flows (CAF) for the recommender system, transforming a simple initial density into more complex ones via a sequence of invertible transformations, until a desired level of complexity is attained. CAF is a non-linear probabilistic approach allowing uncertainty representation and exact tractability of latent-variable inference in item recommendations. Compared to the agnostic-presumed prior approximation used in existing deep generative recommendation approaches, CAF is more effective in estimating the probabilistic posterior and achieves better recommendation accuracy. We conducted extensive experimental evaluations demonstrating that CAF can capture more effective representation of latent factors, resulting in a substantial gain on recommendation compared to the state-of-the-art approaches.

ABSTRACT

Non-negative matrix factorization (NMF) is a knowledge discovery method that is used in many fields. Variational inference and Gibbs sampling methods for it are also well-known. However, the variational approximation error has not been clarified yet, because NMF is not statistically regular and the prior distribution used in variational Bayesian NMF (VBNMF) has zero or divergence points. In this paper, using algebraic geometrical methods, we theoretically analyze the difference in negative log evidence (a.k.a. free energy) between VBNMF and Bayesian NMF, i.e., the Kullback-Leibler divergence between the variational posterior and the true posterior. We derive an upper bound for the learning coefficient (a.k.a. the real log canonical threshold) in Bayesian NMF. By using the upper bound, we find a lower bound for the approximation error, asymptotically. The result quantitatively shows how well the VBNMF algorithm can approximate Bayesian NMF; the lower bound depends on the hyperparameters and the true non-negative rank. A numerical experiment demonstrates the theoretical result.

ABSTRACT

Documentation of experiments is essential for best research practice and ensures scientific transparency and data integrity. Traditionally, the paper lab notebook (pLN) has been employed for documentation of experimental procedures, but over the course of the last decades, the introduction of electronic tools has changed the research landscape and the way that work is performed. Nowadays, almost all data acquisition, analysis, presentation and archiving are done with electronic tools. The use of electronic tools provides many new possibilities, as well as challenges, particularly with respect to documentation and data quality. One of the biggest hurdles is the management of data on different devices with a substantial amount of metadata. Transparency and integrity have to be ensured and must be reflected in documentation within LNs. With this in mind, electronic LNs (eLN) were introduced to make documentation of experiments more straightforward, with the development of enhanced functionality leading gradually to their more widespread use. This chapter gives a general overview of eLNs in the scientific environment with a focus on the advantages of supporting quality and transparency of the research. It provides guidance on adopting an eLN and gives an example on how to set up unique Study-IDs in labs in order to maintain and enhance best practices. Overall, the chapter highlights the central role of eLNs in supporting the documentation and reproducibility of experiments.

ABSTRACT

BACKGROUND: Research is an important activity that informs knowledge and practice. The research culture within the Australian Health Information Management (HIM) profession has not been previously reported. OBJECTIVE: This study explored the perceptions of HIM practitioners about research in their role to establish if there is a research culture in the Australian HIM profession. METHOD: An online survey was distributed to the HIM community using a snowball recruitment strategy. RESULTS: Of the 149 respondents, more than half (54%) identified they possessed research skills from prior education, whilst 40% considered they had a strong knowledgebase in conducting research. However, only a quarter of respondents indicated that they should undertake research in their role. Barriers to undertaking research included recognition, organisational support and time. DISCUSSION: The findings from this study reflected other studies within clinical workforces. The lack of recognition and support to incorporate research into practitioner roles has implications for the profession and its body of knowledge. CONCLUSION: Advocating for research to be incorporated into practitioner roles is required to inform knowledge and practice. Increased professional development opportunities may create a stronger research culture within the HIM profession in Australia and strengthen the position of the profession within health.

ABSTRACT

This paper examines the hosting options for electronic civil registration and vital statistics (CRVS) systems, particularly the use of data centers versus cloud-based solutions. A data center is a facility that houses computer systems and associated hardware and software components, such as network and storage systems, power supplies, environment controls, and security devices. An alternative to using a data center is cloud-based hosting, which is a virtual data center hosted by a public cloud provider. The cloud is used on a pay-as-you-go basis and does not require purchasing and maintaining of hardware for data centers. It also provides more flexibility for continuous innovation in line with evolving information and communications technology.
