Digital Health Literacy of the Population in Germany and Its Association With Physical Health, Mental Health, Life Satisfaction, and Health Behaviors: Nationally Representative Survey Study
Authors: König Lars , Kuhlmey Adelheid , Suhr Ralf
Published: January 2024

Background

Digital health literacy, also known as eHealth literacy, describes the ability to seek, find, understand, and apply health information from the internet to address health problems. The World Health Organization calls for actions to improve digital health literacy. To develop target group–specific digital health literacy interventions, it is necessary to know the digital health literacy of the general population and relevant subgroups.

Objective

This study aims to representatively assess the digital health literacy of the population in Germany and relevant subgroups. The results are meant to facilitate the development of target group–specific digital health literacy interventions. Additionally, this study further explores the associations between digital health literacy and physical health, mental health, life satisfaction, and diverse health behaviors.

Methods

Study participants were drawn from a representative panel of the German-speaking population with internet access. To further increase the representativeness of the sample, survey weights were calculated using an iterative proportional fitting procedure. Participants answered a series of questionnaires regarding their digital health literacy, physical health, mental health, life satisfaction, and diverse health behaviors. Two-sided independent sample t tests were conducted to determine the significant differences between societal subgroups. Pearson correlation coefficients were calculated to explore the correlates of digital health literacy.

Results

Digital health literacy is unevenly distributed within German society. The results of this study suggest that people with a low level of formal education and people with a low social status would benefit from digital health literacy interventions that address their competencies in the domains of information seeking and information appraisal. Furthermore, the results suggest that older people would likely benefit from digital health literacy interventions that address their competencies in the domains of information seeking and also information appraisal. Regarding sex, this study suggests that men might benefit from digital health literacy interventions that specifically address their competencies in the domain of information seeking. Furthermore, digital health literacy is weakly positively correlated with physical health, mental health, life satisfaction, exercise routines, fruit consumption, and vegetable consumption.

Conclusions

Overall, the results of this study demonstrate that digital health literacy is associated with diverse health outcomes and behaviors. Furthermore, the results provide a starting point for the development of target group–specific digital health literacy interventions.
Barriers and Implications of 5G Technology Adoption for Hospitals in Western China: Integrated Interpretive Structural Modeling and Decision-Making Trial and Evaluation Laboratory Analysis (Preprint)
Authors: Zhou Linyun , Jiang Minghuan , Duan Ran , Zuo Feng , Li Zongfang , Xu Songhua
Published: January 2024

BACKGROUND

5G technology is gaining traction in Chinese hospitals for its potential to enhance patient care and internal management. However, various barriers hinder its implementation in clinical settings, and studies on their relevance and importance are scarce.

OBJECTIVE

This study aimed to identify critical barriers hampering the effective implementation of 5G in hospitals in Western China, to identify interaction relationships and priorities of the above-identified barriers, and to assess the intensity of the relationships and cause-and-effect relations between the adoption barriers.

METHODS

This paper uses the Delphi expert consultation method to determine key barriers to 5G adoption in Western China hospitals, the interpretive structural modeling to uncover interaction relationships and priorities, and the decision-making trial and evaluation laboratory method to reveal cause-and-effect relationships and their intensity levels.

RESULTS

In total, 14 barriers were determined by literature review and the Delphi method. Among these, “lack of policies on ethics, rights, and responsibilities in core health care scenarios” emerged as the fundamental influencing factor in the entire system, as it was the only factor at the bottom level of the interpretive structural model. Overall, 8 barriers were classified as the “cause group,” and 6 as the “effect group” by the decision-making trial and evaluation laboratory method. “High expense” and “organizational barriers within hospitals” were determined as the most significant driving barrier (the highest R–C value of 1.361) and the most critical barrier (the highest R+C value of 4.317), respectively.

CONCLUSIONS

Promoting the integration of 5G in hospitals in Western China faces multiple complex and interrelated barriers. The study provides valuable quantitative evidence and a comprehensive approach for regulatory authorities, hospitals, and telecom operators, helping them develop strategic pathways for promoting widespread 5G adoption in health care. It is suggested that the stakeholders cooperate to explore and solve the problems in the 5G medical care era, aiming to achieve the coverage of 5G medical care across the country. To our best knowledge, this study is the first academic exploration systematically analyzing factors resisting 5G integration in Chinese hospitals, and it may give subsequent researchers a solid foundation for further studying the application and development of 5G in health care.
Hand Written Character Recognition Using CNN Model
Authors: Jain Dr. Lokesh
Published: January 2024

Abstract: Handwritten character recognition (HWR) plays a critical role in document processing, robotic automation, and historical document analysis. While traditional methods relied on template matching and feature engineering, these often struggled with diverse writing styles and noise. Convolutional neural networks (CNNs) have emerged as a powerful alternative, achieving remarkable accuracy in HWR tasks. This paper delves into enhancing HWR performance using CNNs on the EMNIST Balanced dataset. We investigate the impact of data augmentation techniques on model generalizability and propose a custom architecture optimized for the task. Through detailed analysis of performance metrics, confusion matrices, and visualization of predictions, we gain valuable insights into the model's behavior and potential areas for improvement.

Authors: Kim Sung-eun , Lee Ae-ri , Lee In
Published: January 2024

Objectives: This study presents evidence by analyzing the research trends in acupuncture treatment for cluster headache in the last 10 years.Methods: Randomized controlled trials (RCTs) about acupuncture for cluster headache were searched from the China National Knowledge Infrastructure, PubMed, Cochrane Library, Oriental Medicine Advanced Searching Integrated System, ScienceON, Korean Studies Information Service System, and Research Information Sharing Service. The search terms were the combinations of “cluster headache”, “acupuncture”, and “needle therapy”, and the articles were restricted to those published between 2013 and 2023. Only RCTs were selected. The risk of bias (RoB) was assessed according to the revised Cochrane RoB2 criteria.Results: Six RCTs were selected and analyzed in this review. All selected studies were conducted in China. All RCTs comprised 628 participants. Manual acupuncture was used in all studies. Acupuncture targeting the sphenopalatine ganglion was performed in two papers published after 2020. ST8, Ex-HIN3, and GB14 were the most frequently used acupoints in acupuncture treatment. The most commonly used indicators for evaluation were headache attack frequency, clinical efficacy, and the visual analog scale. In each study, adding acupuncture treatment to conventional therapy had significant effects in relieving the symptoms of cluster headaches.Conclusion: The results suggest that acupuncture is an effective treatment for cluster headache. To ensure objective evidence for the effectiveness of acupuncture treatment in cluster headache, it is important to continue large-scale case reports and RCTs.

Authors: An Da-young , Kim Chae-eun , Kim Mi-kyung , Sun Seung-ho
Published: January 2024

A 67-year-old female patient diagnosed with acute transverse myelitis visited our hospital in February 2023. Consultation papers indicated that she was diagnosed with acute transverse myelitis and that she complained of quadriparesis and numbness in both hands and feet. However, her spine magnetic resonance imaging (MRI) did not clearly indicate that she suffered from acute transverse myelitis. She was then sent to a high-level hospital and diagnosed with Guillain-Barre Syndrome through electromyography, cerebrospinal fluid test, and spine MRI. On March 2023, she visited our hospital again, still complaining about weakness in both hands and inability to walk. She was treated with Korean medicine, including acupuncture, electroacupuncture, pharmacopuncture, and herbal medicine such as Yanggyeoksanhwatang and Sipimijihwang-tanggami. After three months, she was discharged on cane walking. The manual muscle test (MMT) grade of her upper limbs increased from 3-/3-/3-/3- (shoulder/elbow/wrist/fingers) to 4/4/4/3+, and the MMT grade of her lower limbs increased from 2/2/2/2 (pelvis/knee/ankle/feet) to 4/4/4-/4-. Her numbness in both feet disappeared, and her numbness in both hands decreased from a numeric rating scale of 7 to 2. No adverse events were reported during treatment. This case implies the therapeutic potential of Korean medicine for Guillain-Barre Syndrome, especially for those who had delayed diagnosis and missed the opportunity to get plasma exchange.

Analyzing Changes in The Characteristics of Commercial Districts with Local Growth Based on GIS: Focused on the Hong-dae and Seong-su Districts in Seoul
Authors:   Residential Environment Institute Of Korea, Song Ji-Hyun , Han Yoojin
Published: January 2024

With the increasing interest in neighborhoods, the concept of “local” has emerged as a new economic force in the small business industry. In this context, the purpose of this study is to analyze the characteristics of changes in local business districts as they grow, and to provide valuable data for site selection and industry choices, which are crucial for small business startups. Initially, we explored the changes in population and stores over five years (2017, 2022) in Hong-dae and Seong-su business districts, which are representative local areas in South Korea. Population factors included the number of young adults, the number of single-person households, and the floating population. Store information included restaurant addresses, specific business types, and opening/closing dates, which were analyzed using Geographic Information Systems (GIS). The population factors of the Seong-su business district, which is in a period of local growth, all increased, and stores concentrated around the initial formation point of the local district and expanded into alleys. In terms of business type, there was a significant increase in the proportion of cafes, western food, Japanese food, and sentimental bars. In contrast, in the Hong-dae business district, where localization has already been activated, there has been no significant change in the resident population and specific business type. However, the concentration of stores has spread more widely to alleys and non-core areas. Therefore, small business owners who start a local business should base their decisions on the characteristics of changes as the local business district grows. They should consider factors such as the influx of the youth population when choosing a location and a type of business for successful operation.
Radioisotope diagnostics of endogenous ACTH-dependent hypercorticism: a review
Authors: Khoroshavina А. А. , Orlova G. A. , Ryzhkova D. V.
Published: January 2024

INTRODUCTION: The literature review presents the possibilities of existing methods of radionuclide diagnosis of endogenous ACTH-dependent hypercorticism, which includes Itsenko-Cushing’s disease and ectopic ACTH syndrome. The similar clinical picture of these pathologies significantly complicates their differential diagnosis. Localization of corticotropinoma, especially in patients with persistent Cushing’s disease, and ectopic focus of ACTH hyperproduction also causes difficulties.OBJECTIVE: To analyze the available foreign and domestic literature to determine the possibilities of radionuclide imaging methods in the diagnosis of endogenous ACTH-dependent hypercorticism.MATERIALS AND METHODS: A search of scientifiс publications and clinical recommendations in the information and analytical systems PudMed and elibrary over the past twenty years, dedicated to the diagnosis of Itsenko-Cushing’s disease and ectopic ACTH syndrome using radioisotope diagnostic methods by keywords «Itsenko-Cushing’s disease», «ectopic ACTH syndrome», «radionuclide diagnostics», «scintigraphy», «SPECT», «PET».RESULTS: The presented review demonstrated the broad possibilities and prospects of using modern radioisotope imaging methods in the diagnosis of endogenous ACTH-dependent hypercorticism. Radionuclide imaging methods make it possible to conduct a study in the «whole body» mode, which makes it possible to detect not only the primary tumor focus, but also metastases in patients with ectopic ACTH syndrome in one study. In addition, the use of scintigraphy or positron emission tomography with labeled somatostatin analogues makes it possible to predict the effectiveness of treatment of formations producing adrenocorticotropic hormone with somatostatin analogues, which is important when planning antitumor therapy.CONCLUSION: The use of radioisotope diagnostic methods significantly increases the accuracy of topical diagnosis of a tumor focus, allows for an assessment of the prevalence of the tumor process and the selection of patients for antitumor therapy using somatostatin analogues.

Published: January 2024

INTRODUCTION: Currently, the most common variant of the reproductive system disorders, in particular menstrual cycle disorders, in adolescent girls is oligomenorrhea. In situations after a complete diagnostic screening no organic and endocrine pathology of the reproductive system is detected in this group of patients, it is possible to conduct functional MRI as a method of identifying cause-and-effect relationships and clarifying the pathogenesis of menstrual disorders.OBJECTIVE: To analyze the available foreign and domestic literature to determine the role of magnetic resonance imaging in the diagnosis of functional brain changes in menstrual disorders in adolescent girls.MATERIALS AND METHODS: A search was conducted for scientific publications in the information and analytical systems PubMed and Google Scholar for 2013–2023 by keywords: «resting-state functional MRI» («functional resting MRI»), «oligomenorrhhea» («oligomenorrhea»), «adolescent girls» («teenage girls»), «reproductive system functional disorders» («functional disorders of the reproductive system»), «magnetic resonance imaging» («magnetic resonance imaging»), «diagnostic radiology» («radiation diagnostics»). 46 publications related to the diagnosis of functional brain changes in menstrual disorders in the form of resting state fMRI were analyzed.RESULTS: Resting state fMRI allows us to assess the basic brain activity in the absence of certain sensory or cognitive stimuli and visualize working networks that include various parts of the brain demonstrating synchronous changes in the BOLD-signal at rest. There are a number of patterns of changes in the BOLD-signal that can be observed in various phases of the menstrual cycle, as well as under the influence of stress factors, which makes it possible to visualize the morphological substrate of oligomenorrhea that occurs against the background of the absence of organic and endocrine pathology of the reproductive system in adolescent girls. Currently, there is little data in the scientific literature on the use of functional resting MRI in this cohort of patients, however, this method can have a significant impact on the formation of an individual plan for the correction of reproductive disorders in adolescence, and therefore requires further study.CONCLUSION: The use of fMRI can open up new possibilities in the diagnosis of functional brain disorders in girls with «unexplained» oligomenorrhea.

Published: January 2024

INTRODUCTION: Modern and effective diagnosis of osteomyelitis is the basis for successful therapy; at the same time the problem of establishing this pathology, especially in the early stages of the development of the process, has not been completely resolved.OBJECTIVE: To develop of ultrasound imaging of metaepiphyseal osteomyelitis in young children, depending on the duration of the disease.MATERIAL AND METHODS: 108 children (boys — 65% (70/108), girls — 35 (38/108)) from 1 month to 2 years were examined. Children's age from 2 up to 8 months — 57% (62/108), newborns — 26% (27/108). The age of other children: 12% (13/108) — 9–12 months, 5% (6/108) — 1– 2 years. All children underwent x-ray and ultrasound study. The diagnosis of osteomyelitis was verified by joint puncture (n=102), bone puncture (n=57), drainage of periarticular phlegmon (n=12).Statistics: processing of the study results was carried out using the Statistica 13.0 application package (TIBCO Software Inc, 2017). To assess the effectiveness of ultrasound in the diagnosis of acute osteomyelitis, the diagnostic effectiveness and predictive value of positive or negative results were calculated, and the likelihood ratio was calculated.RESULTS: 3 groups were identified depending on the duration of the disease at the time of admission to the hospital: Ia — 1–3 days, Ib — 4–7 days, Group II — 8–14 days, Group III — 15–21 days from the onset of the disease. DE indicators for patients of group Ia: sensitivity — 81.8%, specificity — 60.0%, accuracy — 75%, PV(+)=81.82%; PV(–)=60.00%; OR=4.50. DE indicators for patients in group Ib: sensitivity — 86.6%, specificity — 66.6%, accuracy — 80.95%, PV(+)=87.5%; PV(–)=60.0%; OR=7.00. DE indicators for patients in group II: sensitivity — 92.98%, specificity — 80.0%, accuracy — 93.44%, PV(+)=98.15%; PV(–)=57.14%; OR=37.86. DE indicators for patients of group III: sensitivity — 91.66%, specificity — 91.0%, accuracy — 91.66%, PV(+)=100.0%.DISCUSSION: Ultrasound imaging of acute osteomyelitis in children of group Ia included nonspecific changes in periarticular tissues and had the lowest diagnostic accuracy (75%). Diagnostic accuracy increased in group Ib to 85% due to initial structural changes in the zone of preliminary calcification and hyaline cartilage of the epiphysis. Disease progression in group II was characterized by more distinct structural changes in the metaphysis with an increase in diagnostic accuracy to 93%. In patients of group III, the highest rates of diagnostic accuracy (91.67%) were obtained due to visualization of destructive changes in the epiphysis, metaphysis and zone of preliminary calcification.CONCLUSION: The ability to detect ultrasound signs of acute hematogenous metaepiphyseal osteomyelitis in children will allow the use of this method in the early diagnosis for the timely selection of an adequate treatment tactics.
Multimodal approach in radiation diagnostics to determining the intramedullary phase of strictly hematogenic osteomyelitis in children: a prospective study
Authors: Pozdnjakov A. V. , Lyurov D. A. , Svarich V. G.
Published: January 2024

INTRODUCTION: Despite the fact that acute hematogenous osteomyelitis is classified as a sufficiently studied disease, the percentage of diagnostic errors is still quite high. Timely diagnosis is crucial for the successful outcome of the disease, therefore, visualization should be aimed at early diagnosis and, as a result, successful treatment of the disease.OBJECTIVE: To identify early patterns in the intramedullary phase of the course of acute hematogenous osteomyelitis (CSO) with a multimodal approach of radiation research methods.MATERIALS AND METHODS: Twenty patients underwent a comprehensive examination, including multispiral computed tomography (MSCT) using color mapping techniques.RESULTS: In the intramedullary phase of the course of CSF, no pathological changes were detected during X-ray examination of the affected limb. Ultrasound in 75% of observations revealed a thickening of the periosteum of more than 1 millimeter (mm) in the affected bone. When using MRI in 93% of cases, and with MSCT in 95% of patients, signs of bone marrow edema were detected.DISCUSSION: The role of computed tomography in the diagnosis of acute hematogenous osteomyelitis in children has received significant recognition in pediatric surgical practice in recent years, and the use of MSCT in the diagnosis of CSO has found application in domestic healthcare. At the same time, a fairly large number of researchers reported on the high informativeness of MSCT in the diagnosis of CSOs.CONCLUSION: MSCT using the color mapping technique has a higher specificity compared to MRI and can be used as an integral method of the first level in the diagnosis of the intramedullary phase of the CSF course.
Physics-informed Neural Networks for the Improvement of Platform Magnetometer Measurements
Authors: Styp-Rekowski Kevin , Michaelis Ingo , Korte Monika , Stolle Claudia
Published: January 2024

Space-based measurements of the Earth’s magnetic field with a good
spatiotemporal coverage are needed to understand the complex system of
our surrounding geomagnetic field. High-precision magnetic field
satellite missions form the backbone for sophisticated research, but
they are limited in their coverage. Many satellites carry so-called
platform magnetometers that are part of their attitude and orbit control
systems. These can be re-calibrated by considering different behaviors
of the satellite system, hence reducing their relatively high initial
noise originating from their rough calibration. These platform
magnetometer data obtained from non-dedicated satellite missions
complement the high-precision data by additional coverage in space,
time, and magnetic local times. In this work, we present an extension to
our previous Machine Learning approach for the automatic in-situ
calibration of platform magnetometers. We introduce a new
physics-informed layer incorporating the Biot-Savart formula for dipoles
that can efficiently correct artificial disturbances due to electric
current-induced magnetic fields evoked by the satellite itself. We
demonstrate how magnetic dipoles can be co-estimated in a neural network
for the calibration of platform magnetometers and thus enhance the
Machine Learning-based approach to follow known physical principles.
Here we describe the derivation and assessment of re-calibrated datasets
for two satellite missions, GOCE and GRACE-FO, which are made publicly
available. We achieved a mean residual of about 7 nT and 4 nT for low-
and mid-latitudes, respectively.
The spatiality of citizenship: a good citizen and the state
Authors:   University of Latvia, Advanced Social and Political Research Institute, Strode Ieva
Published: January 2024

Although the concept of citizenship is usually linked to the state, societal processes (globalisation, migration, societal challenges (e.g., ecology), technological developments etc.) are forcing a reconsideration of this assumption. These new factors also affect the normative aspects of citizenship: what does it mean to be a good citizen in this new reality? This article focuses on the relationship between citizenship and space and whether and how these social processes change people's attitudes toward the role of the nation-state. Based on in-depth interviews with Latvian citizens conducted in 2022, it can be concluded that the state is still the primary reference point for citizens when thinking about citizenship, civic duties, and virtues, but the aforementioned societal processes are changing the perception: technological developments make it possible to be a good citizen in several countries at the same time; globalisation makes it possible to get to know and accept diversity, even if global and national interests (and therefore the responsibilities of a good citizen) conflict (e.g. ecological and demographic issues). Latvia's population has also been affected by the transformation of the country's territory - the collapse of the USSR and accession to the European Union - which has had an impact on the sense of belonging and the perception of which countries are "close" and which are "distant.” However, as in theoretical debates, this study shows that the nation-state continues to dominate the understanding of citizenship; rights, responsibilities, and political activities are all discussed in the context of the state.
The analysis of support mechanisms for occupational mobility in the Latvian adult education system
Authors:   Baltic Studies Center, Zabko Oksana
Published: January 2024

With increasing occupational mobility in the Western societies, where, among other drivers, economic cycles and digital transformation brought changes in labour demand, adults’ access to the education system is becoming increasingly important issue. This refers both for upgrading skills and for retraining with a view to occupational change if the labour market demand for the initial occupation has declined significantly. The aim of this article is to analyse the institutional framework of the Latvian adult education and related institutions to assess what opportunities and what obstacles it creates for individuals to undergo the necessary training to enter a new occupation. Theoretically, the article is based on institutionalism theory, which explains the impact of institutions on the economic behaviour of agents, and middle-range theories on the impact of the structure of the education and labour market institutions on occupational mobility prospects. The analysis is based on a systematic examination of the legal acts and their amendments introduced in Latvia since 2009. The data suggest that Latvian institutional environment is generally favourable for occupational change, but specially targeted public policy support is aimed at the upgrading and retraining of medium- and low-skilled workforce, leaving the occupational transition of high-skilled workforce largely to their own discretion.

Published: January 2024

The aim of this research was to examine the effect of fertilizer treatment on
the content of polyphenols in velvetleaf and maize, grown without use of
herbicides under controlled conditions (12h/12h, T 25?/22?C day/night).
Plants were treated with organic - F1 and synthetic fertilizers - F2 and F3.
The content of total phenols, individual polyphenolic acids and antioxidant
activity of plant extracts were examined, as important indicators of the
plant condition and its resistance to oxidative stress. The content of total
phenols was determined spectrophotometrically (modified Folin-Ciocalteu
method). The content of individual polyphenolic acids was determined by the
high-performance liquid chromatography method, while measurement of
polyphenols antioxidant activity was determined by the DPPH method. It was
established that in maize, the application of fertilizers, neither in
monoculture nor in competition with velvetleaf plants, caused statistically
significant changes in the content of polyphenolic acids. However, in
velvetleaf, the use of fertilizers led to an increase in the content of
polyphenolic acids in conditions of competition vs monoculture. The content
of chlorogenic, p-coumaric and trans-ferulic acids was statistically,
significantly higher in plants of velvetleaf competition vs monoculture, and
the content of chlorogenic, p-coumaric and cinnamic acids was lower in
plants of maize competition vs monoculture. A statistically significant
increase in the content of total polyphenols and their antioxidant activity
in velvetleaf plants indicates the difficulty of removing weeds from crops,
especially resistant populations. The research conducted and the results
obtained confirm that weeds in competitive conditions manifest their natural
competitive advantage, which is further enhanced by crop feeding.

Efficacy and cost-effectiveness of darbepoetin alfa once every 4 weeks versus continuous erythropoietin receptor activator once every 4 weeks for anemia correction in patients with chronic kidney disease not on dialysis
Authors: Park Geo Neul , Lee Kyung Ho , Moon Ji Eun , Choi Soo Jeong , Park Moo Yong , Kim Jin Kuk , Yu Byung Chul
Published: January 2024

Background: For anemia management in patients with chronic kidney disease not on dialysis, darbepoetin alfa (DA), which has a shorter half-life but is more inexpensive than continuous erythropoietin receptor activator (CERA), is preferred in Korea. This study evaluated the efficacy, safety, and cost-effectiveness of once-in-4-weeks DA compared with once-in-4-weeks CERA in patients with chronic kidney disease not on dialysis. Methods: In this randomized, prospective, non-inferiority study, 40 erythropoiesis-stimulating agent–naïve patients with chronic kidney disease not on dialysis were randomized 1:1 to the DA group and CERA group. They received the study drug once in 4 weeks during 10- or 12-week correction period and 24-week efficacy evaluation period. The primary outcomes were the mean difference in the changes in hemoglobin levels between baseline and efficacy evaluation period and hemoglobin response rates during the correction period. The secondary outcomes included differences in adverse events and costs. Results: DA was non-inferior to CERA for anemia correction; the mean difference in the change in hemoglobin levels between the groups was –0.070 g/dL (95% confidence interval, –0.730 to 0.590 g/dL). Hemoglobin response rates were 100% with DA and 94.1% with CERA. Adverse events were comparable. The mean cost of DA was approximately one-third that of CERA (34,100 ± 7,600 Korean won/4 weeks vs. 115,500 ± 23,600 Korean won/4 weeks; p < 0.001). Conclusion: Once-in-4-weeks DA safely corrects anemia in erythropoiesis-stimulating agent–naïve patients with chronic kidney disease not on dialysis and is more cost-effective than once-in-4-weeks CERA.
Product Innovation Possibilities by Designing the Smart Phone Exterior Outline Based on 3d Scans of the Hand Imprint
Authors: P Vink
Published: January 2024

Much is happening in the innovation of smart phones. However, the physical form has still much room for improvement. In this study 3d scans of the hand imprint on a clay model are made and transformed into a smart phone exterior outline. The clay model was made by placing clay around a rectengular plate as clay alone would lead to rounded forms that are too far away from current smart phone models. Eleven participants made an imprint using the phone with one hand (right hand) and using the phone two handed. Of both imprints the average was taken and a 3d print was made. Also, a 3d print was made of a traditional phone of the same size. The comfort of these three 3d printed models was evaluated by 20 participants. The result was that the version based on holding the smart phone in the right hand showed more comfort related to the traditional smart phone of the same size. So, physical form adaptation is certainly an area to be studied in innovating smart phones
Common Subjective Mental Workload Assessment Measures: Advantages and Disadvantages
Authors: HR* Mokhtarinia
Published: January 2024

Background: The amount of mental resources required to perform simultaneously a series tasks is considered as mental workload (MWL). High and Low mental workload in the workplace is usually associated with mental fatigue, decreased performance, human error, and even harmful long-term health effects. Among the various MWL assessment techniques, the outcome measures such as questionnaires are easier and more practical in workplace settings. We aimed to compare the three current commonly advocated and used questionnaires. Material and Methods: Three common different outcome measures for evaluation of the MWL are NASA Task Load Index (NASA-TLX), Subjective Workload Assessment Technique (SWAT), and the CarMen-Q workload questionnaire. Among them the NASA-TLX is well known and more popular with six subscales that are used extensively in industrial and official workplaces. SWAT is the simplest one with three dimensions. The NASA-TLX is preferable method because of its higher sensitivity, especially in low MWL conditions. The CarMen-Q questionnaire is a new questionnaire with 29 items and 4 subscales that focuses on cognitive workload and mental fatigue. Conclusion: SWAT is the simplest and less sensitive measure than the NASA-TLX and CarMen-Q questionnaires. In contrast, the NASA-TLX is widely used and more known instrument for MWL evaluation.

Rapid Recovery Pathways after Surgery in Children: A Systematic Review and Meta-Analysis
Authors: Kumba Claudine
Published: January 2024

Introduction: In adult surgical patients rapid recovery pathways after surgery have shown improvement in postoperative complications and length of hospital stay. Enhanced recovery after surgery is a concept which includes patient management protocols beginning from the preoperative period, continues in the intraoperative period and the postoperative period. This concept aims to improve postoperative outcome. In pediatric patients rapid recovery pathways are beginning to develop. This study was undertaken to analyse whether enhanced recovery after surgery improved postoperative outcome in terms of postoperative complications and length of hospital stay in children. Methods: After registration of this study in Prospero under the number [CRD42018103518], a systematic review and meta-analysis of randomised and non randomised trials was realised in April 2019 using electronic databases in children less than 18 years old where enhanced rapid recovery pathways after surgery were applied and compared to standard care. Statistic analysis was realised with RevMan 5.3 software. Results: 6 studies with 1620 children <18 years old were included in hypospadias, idiopathic scoliosis and appendicitis surgery. 1) In 1482 children, the number of patients with postoperative complications (infections, reoperations, bleeding) was lower in the enhanced recovery group, odds ratio 0.49 [0.26-0.91], p=0.02. 2) In 1168 children, length of hospital stay was lower in the enhanced recovery group, p= 0.0002.

Multiple Solitary Plasmacytoma of Chest Wall and Scalp with Extramedullary Solitary Plasmacytoma of Orbit Occurring Simultaneously: A Rare Case Report
Authors: S Gupta
Published: January 2024

Extramedullary plasmacytoma concurrent with multiple solitary plasmacytoma is very rare presentation and multiple myeloma should be excluded very vigilantly in these cases. Though radiotherapy is treatment of choice but conventional oral chemotherapy can also give equivalent results in few cases. Close follow up is required as most of the cases develop multiple myeloma in future. Plasmacytoma of orbit and subcutaneous tissue with no systemic involvement at present may be the first of its kind to be reported to the best of our knowledge. Treatment with alkylating chemotherapy reduces tumour bulk. However, the risk of progression to multiple myeloma being not yet documented should always be kept in mind.

Tidak semua orang mengenal corak kain tenun yang beragam hanya melalui ciri-ciri yang tampak secara visual. Sering kali mereka salah dalam mengenali kain tenun, dikarenakan corak yang bervariasi dan hampir serupa. Salah satu alternatif untuk mengatasi permasalahan tersebut yakni dengan membangun sebuah sistem informasi deteksi corak kain tenun Tradisional Bali. Pada penelitian ini data corak kain yang digunakan sebanyak 210 citra kain, dengan citra yang digunakan sebagai data training sebanyak 80% atau 168 citra dan data testing sebanyak 20% atau 42 citra. Data tersebut dibagi menjadi 6 kelas dari masing-masing kain yang digunakan. Dengan menerapkan Scaling dan Greyscale pada preprocessing dilanjutkan dengan ekstraksi fitur dengan deteksi tepi Sobel sehingga diperoleh fitur yang representatif. Penelitian ini mengimplementasikan algoritma Learning Vector Quantization untuk mengklasifikasi dan mendeteksi citra corak tenun, dan metode Sobel untuk ekstraksi fitur tepi dimana dengan adanya sistem tersebut terbukti dapat digunakan dalam mengenali corak tenun serta sebagai media penyampaian informasi mengenai jenis, asal dan makna dari tiap kain tenun dengan baik. Sistem yang berhasil dibangun diuji dengan dua metode pengujian yaitu Performence Testing dan Pengujian akurasi. Berdasarkan pengujian akurasi dengan menggunakan pengaruh perubahan learning rate, epoh maksimal, dan epsilon sehingga didapatkan parameter learning rate terbaik yaitu 0.06, epoh 20 dan epsilon  0.0001 dari 42 data testing yang digunakan, didapatkan akurasi sebesar 92.86% dengan 39 data corak kain tenun yang dapat dikenali dengan benar. Adapun hasil penelitian menunjukan bahwa dari sistem yang dibangun dapat melakukan klasifikasi dan deteksi corak kain tenun tradisional Bali dimana hasil ekstraksi fitur Sobel berpengaruh terhadap citra yang akan di klasifikasi dan di deteksi. Semakin jelas dan unik citra tepi yang dihasilkan maka akan semakin besar kemungkinan citra tersebut dapat dikenali dengan benar.

Almost all universities in urban areas already use Learning Management Systems (LMS). This obligation forces lecturers to prepare material and put it into Learning Management Systems (LMS). But facts. There are 63% of lecturers who have difficulty compiling online material. The hope is that using Learning Management Systems (LMS) can improve student learning outcomes. This research aims to determine the positive impact of implementing learning in higher education assisted by Learning Management Systems (LMS). The research wants to find out the obstacles and difficulties in implementing Learning Management Systems (LMS) learning. The research method used is a survey by distributing instruments. Data collection technique, by distributing instruments to 132 people consisting of lecturers and students who were directly involved in the learning process. The analysis technique averages the instruments that have been assessed by students and lecturers. The average results are then interpreted into sentences. As a result, lecturers find obstacles and difficulties in using the learning management system in the learning process. Obstacles and difficulties lie in the implementation of material, the use of learning models, and difficulties in assessing student attitudes and skills. It was found that the material was not included in the Learning Management Systems (LMS) but still distributed different media materials so that learning was less effective. Assessment indicators are also not given to students, so students cannot measure their abilities. In conclusion, every lecturer must prepare materials, models, and assessment instruments before using Learning Management Systems (LMS) as a tool to help implement learning in higher education.
