Exploring the multifaceted vulnerabilities of female street child labor in the capital city of Bangladesh

Numerous children experience vulnerability due to their families' profound economic and socio-economic hardships. Among this demographic, females face heightened susceptibility, particularly those engaged in child labor. Dhaka, the capital city of Bangladesh, hosts a substantial population of female child laborers, compounding their precarious circumstances. Hence this study utilizes a qualitative phenomenological approach to investigate the vulnerabilities affecting these female child laborers thoroughly. A total of 25 in-depth interviews were conducted with female child laborers in Dhaka city, following a semi-structured format. NVivo 14 software was instrumental in the systematic coding and analysis of the extensive text data, enhancing the reliability and validity of the findings. This study, therefore, explores various vulnerabilities faced by female child laborers in Dhaka city, including risky health behavior, abusive behavior, sexual harassment, school dropout, unhygienic dietary habits, hazardous work conditions, and substandard living environments. Their socio-economic conditions make them susceptible to physical and mental setbacks, exploitation, and loss of dignity. The study emphasizes the necessity for comprehensive support and breaking the cycle through educational, health, and social initiatives. It offers a detailed portrayal of the living conditions of female child laborers in Dhaka city, providing valuable insights and evidence-based policy prescriptions for policymakers and Non-Government Organizations to formulate effective policies and measures to safeguard this vulnerable community.

Европейская культурная традиция и мы: идеи М.К. Петрова

The subject of the article is the main problems of the European cultural tradition, considered by M.K. Petrov, and the questions of its specificity and continuity in the historical development from ancient philosophy to experimental sci­ence raised by him. The historical and philosophical context of his formation of the original theory of types of cultures is reconstructed. The rejection of He­gelian panlogism and the position on the universality of a linear development that is uniform for all cultures raises the question of the internal sources of cul­tural development. The article shows that Petrov is looking for answers on the paths of linguistics and the hypothesis of linguistic relativity. Turning to ancient philosophy allows Petrov to reconstruct the intellectual events caused by the emergence of language as a human invention, which broke ties with the former world of stable meanings and opened up the space for the emancipa­tion of the word and the desacralization of knowledge. In this context, the article examines a number of controversial issues about the biocode and sociocode, the name and sign that allowed them to remain the center of an extra-biological system of social coding, and about the diversity of cultures in a polycentric world. Questions are raised about the correlation of Petrov’s positions and mo­dern cultural anthropology

A web-based travel package management system integrated with QR code

The tourism industry is associated with people travelling either domestically or abroad, for business, social, or recreational reasons. This industry integrates numerous services and activities such as tourism organization, marketing, hotel industry, transportation services, food and beverage activities, retail stores and various other activities under one umbrella. In addition to generating income and jobs, tourism is the best way to promote the nation's image. As the economy and living conditions have improved, so too has the tourist sector, and more people are turning to vacations as a way to alleviate stress and unwind. Currently, travel agencies handle a lot of data with low efficiency and a lot of mistakes. Therefore, this study developed a comprehensive integration of QR code for package travel management system that caters to users in Malaysia, offering functionalities such as itinerary customization, QR code generation and access to essential travel information. The development of this project adopts the Waterfall Methodology, encompassing phases such as planning, requirement analysis, design, implementation and testing. The application is crafted using the Visual Studio Code. The study conducted a User Acceptance Testing (UAT) using questionnaires to evaluate the system's effectiveness and user-friendliness to thirty respondents including family members of frequent travellers and randomly selected community members. Positive feedbacks with Perceived Ease of Use (PEU) scoring 3.6, Attitude of Using (ATT) at 3.7, Perceived Usefulness (PU) scoring 3.4, and Intention to Use (IU) obtaining 3.9, were gathered from the analysis and findings that emphasizing the QR code system's potential as a cost-effective and efficient solution for travellers to monitor and optimize their travel experiences. Future work involves adding maps for easy navigation and implementing augmented reality (AR) for virtual destination previews.

The exponential growth of nonsurgeons performing fusions for low-back pain.

This study aimed to report changes in utilization and payment trends of low-back pain (LBP) interventions and the impact of nonsurgeon interventionalists on these changes. Medicare Part B national summary data files were used to gather annual utilization and Centers for Medicare and Medicaid Services (CMS) payment data for LBP interventions from 2000 to 2021. Healthcare Common Procedure Coding System (HCPCS) codes were grouped as decompression, spinal fusion, sacroiliac (SI) joint fusion, epidural steroid injections (ESIs), physical therapy (PT), and chiropractic manipulation (Chiro). The total allowed services and payments were collected for each HCPCS group. CMS provider-level files, available from 2013 to 2021, were used to collect neurosurgeon, orthopedic surgeon, and nonsurgeon interventionalist (interventional radiology and pain management) data for each surgical HCPCS code group (decompression, spinal fusion, and SI joint fusion). The United States Consumer Price Index was used to adjust for inflation. From 2000 to 2021, there were 339,720,725 Medicare-approved interventions and payments of approximately $21 billion for LBP (percentage of cumulative payments: 41.8% Chiro, 16.5% ESI, 14.4% spinal fusion, 14.3% PT, 10.2% decompression, and 0.4% SI joint fusion). In a subgroup analysis, spinal fusions for Medicare patients were performed by orthopedic surgeons (59.2%), neurosurgeons (40.6%), and nonsurgeon interventionalists (< 1%) from 2013 to 2021. From 2013 to 2021, neurosurgeon and orthopedic surgeon fusion utilization each grew by < 3% and associated Medicare payments to each specialty declined by 1% each year. During the same period, nonsurgeon interventionalist utilization grew 26% each year and associated Medicare payments to nonsurgeon interventionalists for spine fusions grew 62% each year. In a subgroup analysis, SI joint fusions for Medicare patients were performed by orthopedic surgeons (50.7%), neurosurgeons (24.8%), and nonsurgeon interventionalists (24.5%) from 2018 to 2021. Neurosurgeon utilization of SI joint fusion declined by 1% each year and associated Medicare payments to this group grew 2% each year. Orthopedic surgeon utilization of SI joint fusion declined 1% and associated Medicare payments to this group grew 4% each year. Nonsurgeon interventionalist use of SI joint fusions grew 415% and payments grew 435% each year. The substantial growth in Medicare payments for surgical LBP interventions is disproportionally driven by nonsurgeon interventionalists. The exponential growth of nonsurgeon interventionalists performing spinal fusion surgeries, particularly SI joint fusions, largely accounts for the significant increase in Medicare expenditures.

Encryption algorithm based on improved four-dimensional chaotic system and dynamic DNA encoding

An image encryption algorithm is proposed based on the combination of genetic (DNA) random coding and chaotic mapping. An image encryption algorithm based on an improved new four-dimensional chaotic system and DNA coding is proposed to address the problem that a single coding method is prone to selecting plaintext attacks. Based on a four-dimensional chaotic system existing in the literature, a new four-dimensional hyperchaotic system is obtained through improvement. The initial value of the system is generated based on SHA-256, zigzag transform. The input key and four pseudo-random chaotic sequences are generated iteratively. DNA chunking encoding, arithmetic operation, and decoding are implemented for the image disrupted based on the zigzag transform. The two-dimensional matrix constituted based on the Chaotic Sequence of Chebyshev to obtain the scrambled and diffused ciphertext image. Simulation experiments and security performance analysis show that the algorithm enhances the correlation between the key and the plaintext, the randomness of the encryption process, and effectively improves the anti-attack capability [H. Chen, J. Zhao et al., Appl. Res. Comput. 10, 0434 (2021)]. In this paper, 512 × 512 × 3 peppers color images are used for testing, and the correlation coefficients of adjacent pixels of the encrypted images are all close to 0, and the information entropy is all more significant than 7.997, which is relative to the theoretical value of 8. The experimental results show that the proposed algorithm improves the security of the ciphertext, increases the critical space, and, at the same time, resists various attack methods.

Primary closure of fasciotomies has a reduced complication rate following compartment syndrome in the paediatric population.

Currently no guidance exists within the literature regarding diagnostic criteria or the long-term outcomes for paediatric patients with acute compartment syndrome (ACS). We conducted a retrospective cohort study reviewing all cases of paediatric ACS managed at a single tertiary referral centre with the aim of characterising the factors responsible for the eventual outcomes. The patient cohort was identified retrospectively by interrogating the hospital coding system for all paediatric patients between January 2014 and November 2022. The electronic emergency department, inpatient and operative notes as well as clinic letters for each patient were reviewed and data collected regarding presentation, associated injuries, management and subsequent complications plus length of follow-up. The data was analysed to determine if differences in presentation or management affected long term outcome. The final cohort consisted of 34 patients with a mean age of tenyears at the time of presentation. The mean time from presentation to fasciotomy was 27.6h (range 3.0 - 66.6). There was an overall complication rate of 37.5% with a mean follow-up period of 21months. Patients who had direct closure of their fasciotomy wounds had a significantly lower complications rate and fewer operations compared to those who healed via other wound coverage methods or secondary intention (p < 0.05). Significantly higher complication rates were observed in patients who were unable to have direct wound closure following emergency fasciotomy. This information may be utilised to rationalise long term treatment plans and in counselling of patients and parents.

The limitations of using Medicaid administrative data in abortion research

ObjectivesTo identify limitations of abortion data in national Medicaid claims files by comparing abortion counts in Medicaid claims data with state abortion estimates. Study designWe used procedure (Current Procedural Terminology/Healthcare Common Procedure Coding System) and drug (National Drug Code) codes to identify abortion claims in 2009 and 2010 Medicaid Analytic eXtract (MAX) and 2020 Transformed Medicaid Statistical Information System Analytic File (TAF) data. We compared the number of abortions in MAX and TAF to the number of expected abortions covered by Medicaid overall and by state. Based on recent published research, we estimated expected Medicaid-covered abortions as 62% of total abortions in states using state funds to cover abortion services for Medicaid enrollees and 0.9% in states that follow Hyde restrictions. ResultsMAX data identified 11% (38,668/345,480) of expected Medicaid-covered abortions in 2009 and 13% (44,528/330,801) of expected Medicaid-covered abortions in 2010. In 2020 TAF data, we found 25% (69,728/279,048) of the expected Medicaid-covered abortions. Among the 16 states that used state funds to cover abortions for Medicaid enrollees in 2020, the majority had <10% of expected Medicaid-covered abortions (n = 8). Three states had between 10% and 50% of expected abortions. Four states had between 51% and 75% of expected abortions. One state had insufficient data for reporting. ConclusionsAbortion claims in MAX/TAF are an undercount of abortions covered by Medicaid, and this undercount varies across states. Variation in reporting across states and across time likely introduces bias into research trying to use MAX/TAF abortion claims across states and time. Researchers should use extreme caution when using MAX/TAF for abortion-related research. ImplicationsResearchers should use caution when using the Medicaid Analytic eXtract and Transformed Medicaid Statistical Information System Analytic Files for abortion-related research questions.

Assessing the Customer Perception of Quick Response (QR) Code Application and their Purchase Intention in Penang's Casual Dining Restaurants, Malaysia

In the era of globalization, some individuals no longer need the physical presence of a human to place an order due to extensive technological advancements that have triggered the use of contactless systems such as QR codes. QR codes represent modern technology that is easy to use by simply scanning the QR code at the guest table providing an easier way to access the restaurant menu. Hence, this study aims to assess the customer’s perception of the usefulness of QR code usage at casual dining restaurants and how the ease of use of QR code applications at casual dining restaurants affects their purchase intention. These factors play a crucial role in any technology-driven initiative's long-term adoption and success. Online questionnaires collected data from 299 valid respondents who have experience scanning QR code at particular casual dining restaurants. The findings indicate that the use of QR codes may have significantly influenced customers' purchase decisions, especially among the younger generation. One key reason cited is the ease of reviewing the menu through the QR code system. Therefore, it is recommended that the food service industry must be more accepting of this technology to gain significant advantages from its implementation. Overall, the study clarifies the potential positive aspects of using QR code ordering systems in restaurants and how they might meet the interests and demands of various client segments. Contactless technologies like QR codes are probably going to play a big part in the foodservice sector's continued evolution in terms of improving customer experiences and optimizing business processes.

Development of multi-physics calculation method in lead cooled fast reactor code system MOSASAUR

A full-core three-dimensional multi-physics calculation method was researched based on the Lead cooled fast reactor (LFR) code system MOSASAUR, which is focused on both core steady-state and transient analyses of LFR. In the previous version of MOSASAUR, cross-sections generation module and core steady-state simulation module have been developed. In this research, the stiffness confinement method is employed to solve the time-dependent multi-group neutron transport equation to expand the capabilities of core transient analyses. And the thermal hydraulic calculation method is developed as thermal feedback module for core steady-state and transient analyses. Based on the fixed-point iteration scheme, the neutron module and thermal hydraulic module are coupled at each time step. The LMW benchmark and the problem based on ORAL 19-rod bundle are employed to verify the accuracy of transient calculation and thermal hydraulic module respectively. Finally, the multi-physics calculation method is utilized to simulate the transient process of the MicroURANUS core. The simulation results demonstrate the capability of the constructed multi-physics calculation framework to accurately simulate the transient behaviors of LMRs. Numerical results showed the good accuracy of the newly-developed multi-physics calculation module with MOSASAUR.

Cardiac positron emission tomography and other modalities for coronary artery disease assessment: A snapshot from the medicare data

BackgroundPositron emission tomography (PET) is an important tool for assessing coronary artery disease (CAD), but its widespread utilization is limited due to various factors, including limited local champion availability. This study aims to compare the frequency of PET procedures and their interpreters with other common CAD assessment modalities. MethodsUsing Medicare data, we examined the number of cardiac PET procedures billed and compared them with single-photon emission computed tomography (SPECT), coronary computed tomography angiography (CCTA), stress magnetic resonance imaging (MRI), and stress echocardiography. Healthcare Common Procedure Coding System codes were used to identify procedures. We calculated the total number of PET myocardial perfusion imaging (MPI) procedures, the proportion of PET/CT and myocardial blood flow (MBF) assessments, and the median number of studies read per physician. We also analyzed the trends in the use of different CAD assessment modalities between 2018 and 2022. Descriptive statistics summarized the data. ResultsIn 2022, Medicare billed for 212,106 PET MPI scans. SPECT was six times more frequent (1,343,519), whereas stress echocardiography (201,676) and CCTA (118,734) had similar or lower use. Stress MRI (3,932) was least used. Of the PET MPI scans, 46% were PET/CT, and 39% included MBF measurements. Cardiologists interpreted 86% of PET scans, with a median of 58 studies per reader; 23% interpreted ≤25 studies annually. SPECT had a median of 63 studies per reader, and CCTA, stress MRI, and stress echocardiography had medians of 27, 20, and 24, respectively. PET, CT, and MRI use increased from 2018 to 2022, whereas SPECT and stress echocardiography declined. ConclusionIn the Medicare population, radionuclide perfusion imaging (SPECT and PET) remained the preferred method for assessment of CAD, with SPECT being the most frequently used modality and PET being the second most frequently used modality for this application. However, PET/CT and MBF are underutilized, limiting diagnostic and prognostic capabilities. Efforts to enhance education and awareness of PET's advantages and to address barriers to its wider adoption are essential to maximize its clinical benefits and improve patient outcomes.

Heat pipe type double-containment vessel as passive safety system for small modular reactors

This paper proposes a new concept of a passive safety system for small modular reactors as a heat pipe type double-containment vessel. The proposed system configures an additional vessel outside the existing one and functions as a heat pipe that utilizes phase change heat transfer to reduce the requirement of a large pool design. The double-containment vessel features a design consisting solely of the evaporation and condensation sections for heat pipe function with compactness. The ultimate heat sink only serves as a condenser part for the double-containment vessel, therefore significantly reducing the volume of stored fluid. The study numerically evaluates several postulated accidental cases to compare the performance of the double-containment vessel using the thermal hydraulic system code, MARS-KS. Even for serious conditions such as multiple failure accidents without safety systems operation, the double-containment can secure extra golden time to core damage by more than 2,090 sec compared to the original design. This study highlights the feasibility and potential of the heat pipe-based double-containment vessel as a passive safety system, enhancing the safety and reliability of small modular reactors. This kind of design can provide the advantages of safety and economics in the construction of small modular reactors.

Effective Communication in Action: Unveiling Teacher Speech Acts in Indonesian Language Education

The Community Service (PKM) aims to analyze the speech acts of teachers used when teaching Indonesian subjects to students at Tinggimoncong State Elementary School, Gowa Regency, South Sulawesi Province. This service was carried out by involving Indonesian language teachers as partners in exploring the variety of speech acts used in delivering material in class. This service applied classroom observations, interviews, and recordings as data collection techniques. Data analysis used a qualitative approach, specifically a systematic coding of the observed interactions, to identify the dominant speech acts used by teachers when delivering the material. The results of the service show that the variety of speech acts used by teachers during Indonesian language learning are directive speech acts used to give instructions to students, expressive speech acts used to build emotional relationships with students, commissive speech acts, and declarative speech acts appear in explaining and giving teacher assignments to students. Teachers use assertive speech acts to express, state, and inform about subjects taught in class. This PKM activity also provides training to teachers on the application of speech acts that can increase the effectiveness of learning in the classroom. Implementing the findings positively impacts the communication skills of teachers teaching subjects, mainly Indonesian.

Asynchronous Code Division Multiplexing-Based Visible Light Positioning and Communication Network Using Successive Interference Cancellation Decoding.

In the evolving landscape of sixth-generation wireless communication, the integration of visible light communication (VLC) and visible light positioning (VLP), known as visible light positioning and communication (VLPC), emerges as a pivotal technology. This study addresses the challenges of asynchronous code division multiplexing (ACDM) in VLPC networks, focusing on the enhancement of data transmission quality and positioning accuracy. Firstly, we propose an orthogonal pseudo-random code (OPRC) for ACDM-based VLP systems. Leveraging its excellent correlation properties, VLP signals preserve orthogonality even amidst asynchronous transmissions, achieving sub-centimeter average positioning errors. Next, by combining OPRC with successive interference cancellation decoding (SICD), we propose an enhanced ACDM-based VLPC system that utilizes OPRC for improved signal orthogonality and SICD for progressive elimination of multiple access interference (MAI) among VLPC signals. The results show substantial improvements in bit-error rate (BER) and positioning error (PE), approaching the performance levels observed in synchronized VLPC systems. Specifically, the SICD-OPRC scheme reduces average BER to 4.3 × 10-4 and average PE to 2.7 cm, demonstrating its robustness and superiority in complex asynchronous scenarios.

Using NHS Data to Monitor Trends in the Occurrence of Severe, Food-Induced Allergic Reactions Work Package 1

People with food allergies may experience food allergic reactions due to accidental exposure. These reactions are commonly categorised as non-severe, fatal food anaphylaxis and near-fatal food anaphylaxis. Non-severe allergic reactions to food are more common with an incidence of up to 1,000 times greater than fatal food-related anaphylaxis. However, obtaining accurate data relating to the circumstances under which these reactions occurred is challenging under the current diagnosis coding system used in the National Health Service (NHS). This project addressed two key questions: 1. What are the trends in the occurrence of food hypersensitivity (FHS) reactions and their consequences in terms of healthcare encounters (both to hospital and primary care)? 2. What are the circumstances surrounding severe, life-threatening reactions to food? Approach The researchers used existing NHS datasets (relating to Hospital Admissions, Accident &amp; Emergency visits, Critical Care admissions and Primary care visits) to evaluate healthcare encounters due to food hypersensitivity over the study period. Patient pathways through the healthcare system were also assessed by linking these different datasets. Key Results • Food-induced anaphylaxis represented 29.4% of reported anaphylaxis. admissions, and increased significantly from 1.23 to 4.02 admissions per 100,000 population per annum over the study period. • However, despite an annual increase of 5.7% in hospitalisation for food-induced anaphylaxis between 1998 and 2018, the case fatality rate (proportion of hospital admissions associated with a fatal outcome) more than halved, from 0.7% in 1998 to less than 0.3% in 2018. • 152 deaths were identified during the study period where the cause was very likely to have been food-induced anaphylaxis. • At least 86 (46%) fatalities were triggered by peanut or tree nuts. • Cows’ milk was reported to be the most common cause of fatal anaphylaxis in children aged under 16 years. • Using data from England for the period 2008-2018, the prevalence of food allergy ranged from 4% in preschool-aged children (under 5 years), 1-2% in school-aged children and young people (5 to 20 years) and 0.9% in adults. Although the same methods were used throughout the study period, the statistics presented may be prone to limitations such as miscoding and incomplete datasets. • Prescription of adrenaline auto-injector devices (AAI) are an important risk management intervention in people at risk of food-induced anaphylaxis. However, there is significant under-prescribing of AAI. Data showed that 40% of individuals with prior food-induced anaphylaxis were not prescribed AAI and at least 59% did not have AAI on repeat prescription. • Most healthcare visits for food allergy occurred in general practice. Less than 3% of individuals with a diagnosis of food allergy attended Accident and Emergency during the study period, 2008-2018. Therefore, using hospital data in isolation to analyse patterns of health service utilisation with respect to FHS may not provide a comprehensive overview.

Using NHS Data to Monitor Trends in the Occurrence of Severe, Food-Induced Allergic Reactions Work Package 2

People with food allergies may experience food allergic reactions due to accidental exposure. These reactions are commonly categorised as non-severe, fatal food anaphylaxis and near-fatal food anaphylaxis. Non-severe allergic reactions to food are more common with an incidence of up to 1,000 times greater than fatal food-related anaphylaxis. However, obtaining accurate data relating to the circumstances under which these reactions occurred is challenging under the current diagnosis coding system used in the National Health Service (NHS). This project addressed two key questions: 1. What are the trends in the occurrence of food hypersensitivity (FHS) reactions and their consequences in terms of healthcare encounters (both to hospital and primary care)? 2. What are the circumstances surrounding severe, life-threatening reactions to food? Approach • A UK arm of NORA was established using the same online platform as the existing European Registry. • Participation of healthcare professionals and/or patients to enter relevant information was co-ordinated by BSACI in conjunction with the Paediatric Emergency Research in the United Kingdom Ireland (PERUKI) network. • Different versions of the questionnaire were developed to increase response rates: (1) a comprehensive form mapped to existing NORA data fields for completion by Healthcare Professionals in the non-acute setting; (2) a shorter form with key data fields to increase data reporting in more pressured, acute healthcare settings; and (3) a form for completion by patients or their parent/guardian. Key Results The launch of the UK anaphylaxis registry faced delays and was impacted by significant pressures on NHS services due to the COVID-19 pandemic. This led to a lower than anticipated uptake of the Registry by clinics and Accident &amp; Emergency departments. As a result, only a minority of accidental reactions (less than 5%) were captured in the registry, almost all in children and young people under age 18 years. Some indicative results of this analysis are the following: • 213 cases reported to be due to a food trigger and of these, 208 occurred in children/young people aged 18 years or under. • Common food triggers were peanut, tree nuts (especially cashew), cow’s milk/dairy and hen’s egg. • 47% of reactions occurred after consumption of prepacked food products and in at least 59% of these cases, the allergen was declared as an actual ingredient. Further work would be needed to understand how to optimise reporting of data, for example by reducing the time burden for completion by clinicians and patients.

Integrating 3DVAR and ANN for inversion optimization of physical models of fuel-assembly bowing

This study introduces a novel inversion optimization method for the core physical model of fuel-assembly bowing, integrating measurement data based on three-dimensional variational (3DVAR) data assimilation and artificial neural network (ANN) techniques. Recognizing the deviation between theoretical physical models and actual core conditions due to factors like uneven coolant distribution and fuel-assembly bowing, this work aims to enhance model reliability and simulation accuracy. By generating a dataset through random perturbation and employing ANN for training, the method establishes a relationship between the core physical model and model-simulated values corresponding to measurement data. The construction of the cost function, essential for optimizing the inversion process, is executed using 3DVAR. To verify its validity, the method is implemented, and an inversion optimization process is developed using our self-developed Bamboo-C code system. The optimization process, validated through application in a commercial pressurized water reactor (PWR) in a nuclear power plant (NPP) in China, demonstrates a significant reduction in the relative errors of power distribution, thus affirming the method’s efficacy in achieving a more realistic model of fuel-assembly bowing. The integration of measurement data into the optimization process addresses the critical need for accurate core physical models in nuclear engineering, offering a promising avenue for enhancing the safety and efficiency of nuclear reactor operations.

Quality of parent–child interaction in underserved migrant areas in Kyrgyz Republic: a pilot study

BackgroundAfter societal change in Kyrgyz Republic, the pattern of parent–child interaction in the changing parenting culture is an important factor influencing the positive development of Kyrgyz children. This study is aim to assess the quality of parent–child interactions in Kyrgyzstan by analyzing the interaction patterns and playfulness of children during free play at home.MethodsThis was a descriptive pilot study using video-recorded observations to explore parent–child interactions. The Dyadic Parent–Child Interaction Coding System and a playfulness instrument were used to assess the patterns and quality of the interaction. A total of 20 dyads of children aged 24 to 58 months and their parents, living in migrant communities of Kyrgyzstan, participated in this study.ResultsMajor parent–child interaction patterns included 731 turns of parent–child dyads during 1040 episodes. Verbal as well as nonverbal behaviors of parents were observed while interacting with their children. Parents used direct and indirect commands most frequently, while praise was used the least in interactions. Children frequently used compliance as well as noncompliance when they interacted with their parents. Children had low playfulness scores while interacting with their parents. Cognitive spontaneity was the component with the lowest score among all subdomains of playfulness.ConclusionFuture studies are recommended to develop strategies to facilitate parents’ active interaction with their children, promote children’s playfulness, and improve the quality of their mutual interaction.

Optimizing Integration with the Italian EHR: The Use of LOINC Codes.

According to the regulation "Decreto del Presidente del Consiglio dei Ministri" (DPCM) of September 29, 2015, n.178, the Logical Observation Identifiers Names and Codes (LOINC) system is included among the coding systems adopted in the Italian Electronic Health Record (EHR). As part of the Digital Health Solutions in Community Medicine (DHEAL-COM) project, one key goal is to categorize parameters using international classification systems. This enables the identification of appropriate Information and Communication Technology (ICT) solutions tailored to support people's health needs. Our objective is to incorporate LOINC codes for parameter categorization, thus anticipating the future use of EHR.

The study produced a revised RadLex data model and mapping guide, designed to classify radiology services using TermX. In total, 380 concepts were required to comprehensively describe all 622 procedures examined. Our study demonstrates the effectiveness of TermX in simplifying the process of mapping between code systems, thus enabling more efficient analysis, and reporting of data.

Evaluation of radiation protection effectivity in a cardiac angiography room using visualized scattered radiation distribution

In this study, we devised a radiation protection tool specifically designed for healthcare professionals and students engaged in cardiac catheterization to easily monitor and evaluate scattered radiation distribution across diverse C-arm angles and arbitrary physician associated staff positions—scrub nurse and technologist positions. In this study, scattered radiation distributions in an angiography room were calculated using the Monte Carlo simulation of particle and heavy ion transport code system (PHITS) code. Four visualizations were performed under different C-arm angles with and without radiation protection: (1) a dose profile, (2) a 2D cross-section, (3) a 3D scattered radiation distribution, and (4) a 4D scattered radiation distribution. The simulation results detailing the scattered radiation distribution in PHITS were exported in Visualization Toolkit format and visualized through the open-source visualization application ParaView for analysis. Visualization of the scattered dose showed that dose distribution depends on the C-arm angle and the x-ray machine output parameters (kV, mAs s−1, beam filtration) which depend upon beam angulation to the patient body. When irradiating in the posterior–anterior direction, the protective curtain decreased the dose by 62% at a point 80 cm from the floor, where the physician’s gonads are positioned. Placing the protection board close to the x-ray tube reduced the dose by 24% at a location 160 cm from the floor, where the lens of the eye is situated. Notably, positioning the protection board adjacent to the physician resulted in a 95.4% reduction in incident air kerma. These visualization displays can be combined to understand the spread and direction of the scattered radiation distribution and to determine where and how to operate and place radiation protection devices, accounting for the different beam angulations encountered in interventional cases. This study showed that scatter visualization could be a radiation protection teaching aid for students and medical staff in angiography rooms.
