Efficient color code decoders in d≥2 dimensions from toric code decoders

We introduce an efficient decoder of the color code in d≥2 dimensions, the Restriction Decoder, which uses any d-dimensional toric code decoder combined with a local lifting procedure to find a recovery operation. We prove that the Restriction Decoder successfully corrects errors in the color code if and only if the corresponding toric code decoding succeeds. We also numerically estimate the Restriction Decoder threshold for the color code in two and three dimensions against the bit-flip and phase-flip noise with perfect syndrome extraction. We report that the 2D color code threshold p2D≈10.2% on the square-octagon lattice is on a par with the toric code threshold on the square lattice.

The Circular Economy Transformation of Airports: An Alternative Model for Retail Waste Management

Airport terminals worldwide generate approximately 6 million tons of passenger waste annually. Increased awareness of climate change and global interventions for environmental sustainability requires a reassessment of airports’ current methods of waste management. This paper proposes a new design concept solution called circular airport retail waste management (CAWM) for airport terminal retail waste processing, which aims to reduce and ideally eliminate airport waste ending up in landfill or incineration. Given the need for novelty and challenging the status-quo, the double diamond design process was adopted as the research method. The research began by collating the current practices of retail waste processing in airports via a literature review and field observations. Secondly, a critical analysis of the current processes was conducted to identify the intervention points. Thirdly, a concept solution was developed based on the circular economy (CE) 9R framework. Finally, the CAWM concept was delivered to airport waste management personnel for review. CAWM offers a structured way of airport retail waste management practices, including the segregation of nonrecyclable and recyclable waste (i.e., different bin designs, color coding, harmonization of waste colors, improved instructions and signage, various bin locations, training, and installing more liquid disposal and donation stations). Airports can leverage CAWM for greater efficiency and cost-effectiveness regarding airport terminal waste processing, such that more waste can be diverted from incineration and landfill to recovery, which will subsequently help airports achieve net-zero targets. This research contributes to the extant CE literature, especially in the aviation industry context, where the academic discourse surrounding this subject and its peculiarities are limited.

Perception of Teachers and Principals on Professional Development Needs, Types, Impacts, and Challenges: A Case Study under Trashigang Dzongkhag

This research was to study the perception of teachers and Principals on professional development needs, types, impacts, and challenges faced by surveying their views of them under Trashigang Dzongkhag. The objectives were to study the perception of teachers and principals on the most needed PD programs, that have produced the highest impact on teachers' knowledge of teaching, and challenges faced in professional development programs. The researcher used structured interviews and PD document analysis to apply qualitative research techniques. The study used a case study design and random sampling. Crest well's six steps of thematic analysis of the data were followed by applying color coding of the interviews and documents. Questionnaires were distributed to teachers and principals through the mail.
 Findings indicated that the most needed professional development programs for teachers were ICT, 21st-century teaching pedagogies, subject content, action research, effective communication, curriculum instruction, and place-based education. It indicates that attending professional development has impacted teaching skills, professional growth, subject delivery, and producing competent learners. It revealed that they had faced the most challenges in attending professional development programs due to time constraints, limited resources, lack of opportunities, qualified facilitators, and nomination of the right participants for the program. Limited financial resources and workload hamper teachers from participating in the professional development program.
 It is recommended that the Ministry of Education, Dzongkhag Education office, and schools ensure that PD programs must be strictly scheduled on suitable days to focus more on Content and pedagogical development of PD for teachers.

Morphine Spinal Anesthesia for Cesarean Section at the Regional Hospital of Saint Louis in Senegal: About 119 Cases Collected

Introduction: Post-operative pain management has been the subject of several studies worldwide. Cesarean section is a commonly performed procedure and can lead to severe pain. This study aimed to determine the quality of post-cesarean analgesia by intrathecal administration of 100 micrograms of morphine. Patients and Methods: We conducted an analytical and descriptive study with prospective data collection during one month. We included all women who underwent a spinal caesarean section. Results: During the study period, a total of 119 women were enrolled. The mean age of the parturients was 27.85. High blood pressure and obesity were the most common comorbidities in 9.242% and 5.09% of the women respectively, and 31.93% had a history of caesarean section. Cesarean sections were performed according to the level of urgency based on the colour code. Scheduled caesarean sections were performed in 64.7% of cases. Women had an APFEL score of 3 in 95% of cases. Bupivacaine 7.5mg was administered in 96.63% of cases. The average dose of ephedrine administered before fetal extraction was 3.96mg. Oxytocin was the most administered uterotonic in 73.94%. The APGAR score at birth was greater than 7 in 95.79% of cases. No patient expressed a need for additional analgesics after lifting the motor block. No respiratory or neurological complications of morphine were noted. Pruritus was present in 24.36% of cases, whereas nausea and vomiting were reported in 17.64%. There were no cases of acute urine retention. The average time for the resumption of bowel movement was 13.67 hours. Discussion and Conclusion: Morphine spinal analgesia is an effective technique for the management of post-cesarean pain. The reduction of the morphine dose to 100 micrograms and the preventive addition of dexamethasone are two key factors in accelerated rehabilitation after surgery.

Synthesis, crystal growth, structural and physicochemical properties of N-methylurea benzoic acid single crystal for non-linear optical applications

The organic single crystal of N-methylurea benzoic acid (NMUB) was synthesized and successfully grown from a slow evaporation solution growth technique for the first time in literature. The structure of the NMUB single crystal was analyzed by Single crystal X-ray diffraction (SCXRD); the crystallization of the NMUB crystal was a monoclinic crystal system with the space group P21/c. The crystal structure was combined by the carboxylic groups of H- atoms in benzoic acid with protonated N-methylurea anions. The FTIR and 1H, 13C NMR chemical shifts were analyzed by distinct vibrational groups and molecular structures. The PXRD ascertains the grown crystal crystallographic planes and crystalline nature. The Hirshfeld surfaces analysis determines the theoretical inter and intra-molecular interaction with the aid of color coding. The UV-Vis NIR spectra revealed the low absorption edge, and the optical band gap was anticipated. The crystal thermal and mechanical stability was analyzed by TG/DTA, Vickers microhardness, and void volume. The laser utility limitation for the crystal was determined through laser beam irradiated LDT analysis. The third-order optical non-linear parameters were determined from the z-scan technique.

Visual growth of nano-HOFs for low‐power memristive spiking neuromorphic system

Memristors showcasing progressive conductance modulation are now recognized as one of the most promising candidates to act like electronic synapses inside computer circuits, mimicking the behavior of neurons in the human brain. Recently, the concept of biomimic synapse devices based on organic materials has attracted enormous interest, nevertheless, largely limited by their poor electrical conductivity and charge transfer capacity. Here, 2D ribbon-structured hydrogen-bonded organic frameworks (Nano-HOFs) embedded with the transition metal nanoparticles are firstly grown under visual surveillance to serve as highly reliable memristive materials, where the localized surface plasmon resonance effect and enhanced charge-carrier transport are strongly confirmed. The HOFs@Au-based memristor presents gradient electrical conductances under continuous voltage sweep or pulse algorithms, thereby closely simulating the synaptic behaviors in biological neurons. The newly designed artificial synapses owns an ultra-low areal switching energy density (35.8 fJ µm−2) and maintains extremely stable synaptic functions even after being exposed to ambient conditions over 6 months without any encapsulation. Further brain-inspired cognitive systems are established to realize color coding and image cognition in a secure way. This work creates a precedent for developing highly viable Nano-HOFs materials to manipulate artificial synapse mimicking, prospective neuromorphic computing and intelligent cognition applications.

Biomedical Waste Management and Its Importance: A Systematic Review.

The waste generated in various hospitals and healthcare facilities, including the waste of industries, can be grouped under biomedical waste (BMW). The constituents of this type of waste are various infectious and hazardous materials. This waste is then identified, segregated, and treated scientifically. There is an inevitable need for healthcare professionals to have adequate knowledge and a proper attitude towards BMW and its management. BMW generated can either be solid or liquid waste comprising infectious or potentially infectious materials, such as medical, research, or laboratory waste. There is a high possibility that inappropriate management of BMW can cause infections to healthcare workers, the patients visiting the facilities, and the surrounding environment and community. BMW can also be classified into general, pathological, radioactive, chemical, infectious, sharps, pharmaceuticals, or pressurized wastes. India has well-established rules for the proper handling and management of BMW.Biomedical Waste Management Rules, 2016 (BMWM Rules, 2016) specify that every healthcare facility shall take all necessary steps to ensure that BMW is handled without any adverse effect on human and environmental health. This document contains six schedules, including the category of BMW, the color coding and type of containers, and labels for BMW containers or bags, which should be non-washable and visible. A label for the transportation of BMW containers, the standard for treatment and disposal, and the schedule for waste treatment facilities such as incinerators and autoclaves are included in the schedule. The new rules established in India are meant to improve the segregation, transportation, disposal methods, and treatment of BMW. This proper management is intended to decrease environmental pollution because, if not managed properly, BMW can cause air, water, and land pollution. Collective teamwork with committed government support in finance and infrastructure development is a very important requirement for the effective disposal of BMW. Devoted healthcare workers and facilities are also significant. Further, the proper and continuous monitoring of BMW is a vital necessity. Therefore, developing environmentally friendly methods and the right plan and protocols for the disposal of BMW is very important to achieve a goal of a green and clean environment. The aim of this review article is to provide systematic evidence-based information along with a comprehensive study of BMW in an organized manner.

Use of Colour Coding to Assess the Effects of Haloperidol on Animal Behaviour in the Open Field Test

Development of novel approaches to behavioural test data analysis is of considerable importance to fundamental research as well as experimental neuropharmacology. Antipsychotic agents used to treat positive and negative symptoms in schizophrenia are of particular interest to current research. Despite that antipsychotics exert potent effects on animal behaviour in simple behavioural tests, they can be difficult to distinguish from other central nervous system-depressing agents, such as sedatives. In this paper, we propose colour coding of video sequence as a method for the analysis of behavioural pattern structure in rats, using the effects of haloperidol, a typical antipsychotic, in the Open field test, as an example. The study was carried out in outbred albino male rats weighing 250–300 g. 3 min long video sequences of rat behaviour in the Open field were processed using Python and the OpenCV library in the Google Colab 3 environment. Colour coding allowed for the marking up and overlaying in a single frame the present (t = 0), nearest-future (t = 0.33 s), and the less-near-future (t = 1.66 s) location of an animal in the arena. Using the proposed method, we were able to detect specific effects of haloperidol on animal behavioural patterns which are undetectable using conventional behavioural data analysis techniques for this test. The three-timepoint colour coding method we propose proved effective for data analysis and processing, and the results were in accordance with other author’s data, obtained using computerized as well as conventional visualization techniques.

First report of Diplodia mutila causing wood necrosis in European hazelnut in Chile.

In Chile, the planted area of European hazelnut (Corylus avellana L.) reaches around 30,000 hectares, mainly concentrated in the central and southern area of the country where climate and soil provide a natural environment well suited to growing this species. Only a few diseases affect this nut tree in Chile. During the spring seasons in 2018 and 2020, European hazelnut plants (6 to 20% of incidence) exhibited wood necrosis and vascular discoloration of branches, with reduced growth, cankers and wilt branches, in orchards located in San Clemente and Curicó, Maule Region, Bulnes and El Carmen, Ñuble Region, Chile (36°45'-36°54' S; 71°03'-72°26' W). Symptomatic tissues were surface disinfected using a ~1% commercial sodium hypochlorite solution. Disinfected tissues were cut longitudinally, placed onto potato dextrose agar (PDA, Difco) plates, and incubated at 25 °C in the dark for 48 hours. Fungal hyphal tips were taken and placed on PDA medium. A fungal species was consistently isolated from these lignified tissues. The mycelium was initially translucent (turning white in appearance), while the mature mycelium was aerial, varying in color from pale to dark gray (Munsell color code: colony edge mycelium 6Y-6 4 / 5G and colony center mycelium B6-PB 7 / 5PB). The production of pycnidia and conidia was induced using pine needles in water agar medium and incubated in the dark for 10 days. Hyaline unicellular conidia of 25 ± 1.1 µm (range 23.9 to 26.1 µm) long and 11 ± 0.5 µm (Range 10.5 to 11.5 µm) wide (n = 50) were obtained from black pycnidia. Based on the cultural and morphological characteristics observed, the pathogen was identified as a possible species of the family Botryosphaeriaceae (20 isolates). Molecular techniques were used to identify the species of pathogen, and three isolates (F154, F199, and F167) were analyzed by using Multilocus sequence typing to confirm the identity of the pathogen. Genes ITS (internal transcribed spacer region), tef-1 (translation elongation factor 1-alpha) and β-tub (β-tubulin) were amplified using endpoint PCR, with primers ITS1/ITS4 (White et al., 1990), EF1-728F/EF1-986R (Carbone & Kohn, 1999) and Bt2a/Bt2b (Glass & Donaldson, 1995), respectively. The segments were sequenced using the same primers, deposited in Gen Bank, and the accession numbers for each isolate were OM993582, OM993583, ON003481 for ITS, ON054936, ON054938, ON054937 for tef1 and ON054939, ON054941, ON054940 for β-tub, respectively. A phylogenetic tree was constructed using the maximum likelihood statistical method with the Tamura-Nei model based on a concatenated dataset of ITS region, tef1 and β-tubulin gene using Mega-X, and the three Chilean isolates (F154, F199, and F167) formed a single clade with the reference isolates of Diplodia mutila (Fr.) Mont. BLAST algorithm analyses indicated 100% identity to D. mutila for ITS (accession NR_144906), for tef-1 (accession MK573559), and for β-tubulin (accession MG952719). The pathogenicity of the three isolates was validated through Koch's postulates. For this purpose, a trial was established in 6-year-old European hazelnut plants cv. Tonda Di Giffoni. Ten healthy branches were individually inoculated using actively growing mycelial discs from each isolate, while a disc of PDA without fungus was used as a control. Holes of 5-mm diameter were inoculated, making sure the mycelium was in contact with the wood. Finally, the wounds were sealed with plastic film to prevent external contamination and improve humidity conditions. After 120 days, each branch was cut longitudinal-sectioned to verify the presence of wood necrosis which arose between 3.0 to 16.2 mm of length around the point of inoculation. No necrosis was observed in the control. To confirm pathogenicity, infected tissues were cut into small pieces with sterile knives and scalpels, and surface disinfected with a 1% sodium hypochlorite solution for 1 min. The disinfected tissues were placed on PDA medium and incubated at 25°C in the dark until fungal growth was observed. Hyphal tips were taken from the mycelia developed from the pieces of wood, and placed on PDA medium in order to obtain pure isolates. The pathogenicity of the D. mutila isolates F154 and F199 was observed in 100% of the inoculated branches, while isolate F167 showed symptoms in 85% of the branches. The reisolated strains showed similar mycelial growth and microscopic fungal structures to those observed in the isolates used for inoculation. This is the first report of D. mutila affecting European hazelnut in Chile. This fungus has been recently reported affecting hazelnut in Oregon, USA (Wiman et al., 2019), causing similar symptoms to those observed in our study. In addition, D. mutila has been reported infecting walnut in Chile (Diaz et al. 2018) and native forest trees, specifically Araucaria araucana in Chile (Besoain et al., 2017). The presence of D. mutila in commercial hazelnut orchards in Chile highlights the need for epidemiological studies in order to understand the characteristics and impact of this pathogen and, based on this, develop adequate phytosanitary programs for its control.

Colour-cued paragraph writing instruction for students with learning disabilities.

Expository paragraph writing is difficult to learn and teach. For many students, particularly those with learning disabilities, it is difficult to manage the multiple, simultaneous complex processes required for success. And for their teachers, writing is the content area in which they feel least prepared to teach. This intervention applied the concept of reverse engineering to instructional design to teach expository paragraph writing using a color-cued graphic organizer. The study evaluated the effects of using a systematic color code to highlight the alignment of where ideas originate in a graphic organizer to their development into a sentence within a well-organized expository paragraph. Using a single case research design, with a pre- and post-intervention assessments, students (n=5) with dyslexia improved their expository paragraph knowledge and skills. Percentage of non-overlapping data and Tau analyses indicate a large to very large effect of the 2-week intervention. Results, suggestions for further research, and implications for practice are discussed.

Characterization of Galectin Fusion Proteins with Glycoprotein Affinity Columns and Binding Assays.

Galectins are β-galactosyl-binding proteins that fulfill essential physiological functions. In the biotechnological field, galectins are versatile tools, such as in the development of biomaterial coatings or the early-stage diagnosis of cancer diseases. Recently, we introduced galectin-1 (Gal-1) and galectin-3 (Gal-3) as fusion proteins of a His6-tag, a SNAP-tag, and a fluorescent protein. We characterized their binding in ELISA-type assays and their application in cell-surface binding. In the present study, we have constructed further fusion proteins of galectins with fluorescent protein color code. The fusion proteins of Gal-1, Gal-3, and Gal-8 were purified by affinity chromatography. For this, we have prepared glycoprotein affinity resins based on asialofetuin (ASF) and fetuin and combined this in a two-step purification with Immobilized Metal Affinity chromatography (IMAC) to get pure and active galectins. Purified galectin fractions were analyzed by size-exclusion chromatography. The binding characteristics to ASF of solely His6-tagged galectins and galectin fusion proteins were compared. As an example, we demonstrate a 1.6-3-fold increase in binding efficiency for HSYGal-3 (His6-SNAP-yellow fluorescent protein-Gal-3) compared to the HGal-3 (His6-Gal-3). Our results reveal an apparent higher binding efficiency for galectin SNAP-tag fusion proteins compared to His6-tagged galectins, which are independent of the purification mode. This is also demonstrated by the binding of galectin fusion proteins to extracellular glycoconjugates laminin, fibronectin, and collagen IV. Our results indicate the probable involvement of the SNAP-tag in apparently higher binding signals, which we discuss in this study.

Neurofibromatosis Type 1-Associated Plexiform Neurofibromas of the Face and Adjacent Head Regions: Topography of Lesions and Surgical Treatment Data of 179 Patients

IntroductionFacial plexiform neurofibromas (FPNF) are rare tumors frequently diagnosed in patients with neurofibromatosis type 1 (NF1), a tumor predisposition syndrome. FPNF often grows invasively and destructively, which may complicate surgical treatment. Data on the frequency, location, and surgical procedures of patients with NF1-associated FPNF are scarce. This study provides treatment data from a nationally networked reference center for the treatment of NF1 patients.Material and MethodsThe localization and treatment data of 179 NF1 patients with FPNF were analyzed. Photographically documented tumors of the study area, further determined by imaging, were manually transferred to a facial scheme and digitized. The digitized registrations of the facial extensions of the tumors of each patient were overlaid in a single image (Photoshop™), so that the file of the facial scheme contained the sum of the tumor localization. Finally, the frequency of tumor localization was indicated with a color code. The frequency of tumor extension-related coded colors was applied to outline the lesions' topography on schematic face drawings (heat map).ResultsThe distribution of the tumors showed no side preference. The need for the treatment of patients with orbital/periorbital manifestations became evident in the graphic representations. Tumors do not respect anatomical units. However, the classification of the face according to dermatomes, especially the trigeminal nerve, offers indications of tumor spread and guides treatment planning. The mean number of surgical measures per patient was 2.21 (median: 1). Extensive swelling, hematoma, and delayed wound healing were all common postoperative complications.ConclusionThe color-coded, schematic overview of the frequency distribution of cutaneous tumor spread in NF1 patients with FPNF illustrates the importance of orbital/periorbital and cheek tumor manifestations in patients' treatment needs. The imaging procedure is suitable for controlling natural tumor growth in the same way as the documentation of the post-surgical course. Repeated interventions in the region are included in surgical planning of the progressing tumor disease.

Factors Affecting the Not Implementation of Medical Record Tracer

Tracer is an important tool in controlling the use of medical record files. Usually used to replace medical records that are out of storage. These exit instructions remain in storage until the borrowed medical records are returned and stored again. This exit sign is equipped with a pocket for storage of request slips. The purpose of this study was to determine the factors that influence the non-application of a medical record tracer at the Pratama Klambir clinic in 2021. This research method used a descriptive qualitative method which was carried out from November to completion. The informants of this research were 6 informants, namely 1 key informant, 4 main informants and 1 triangular informant obtained by purposive sampling technique.The study obtained the man factor (human resources), namely the education of officers who did not graduate from medical records and had never attended training, machines (machines) that had not been applied to the use of tracers and lacked storage racks, materials (raw materials), namely the folders used were still made of plastic and had not used color codes, methods (methods/procedures), namely SPO had not been carried out properly, and money, namely there was a shortage of money. The conclusion in this study is that there are many factors (human resources), machines (machines), materials (raw materials), method (methods/procedures) and money (money) which causes the medical record tracer not to be applied at the Pratama Klambir clinic.

Electrochemical, Biological, and Technological Properties of Anodized Titanium for Color Coded Implants.

Anodization coloring of titanium tools or implants is one of the common methods for the differentiation of each application by its size or type. Commercial purity titanium grade 4 plates (50 × 20 × 0.1 mm) were tested to obtain their electrochemical and other technological properties. The coloring process was done using the potential of 15, 30, 45, 60, and 75 Volts for 5 s in 1 wt. % citric acid in demineralized water solution. Organic acids solutions generally produce better surface quality compared to inorganic acids. The contact angle of colored surfaces was measured by the sessile drop method. Electrochemical impedance spectroscopy and potentiodynamic polarization were used for the determination of selected electrochemical and corrosion parameters of the tested surfaces. It was found that the anodization process decreases corrosion potential significantly. It was also confirmed that a higher potential used for anodization results in higher polarization resistance but also a decrease in corrosion potential. The anodization process at 75 V produces surfaces with the lowest corrosion rate under 1 nm/year and the noblest corrosion potential. It was confirmed that the anodization process in citric acid does not affect titanium cytotoxicity.

Current status of neonatal death in a second level of care hospital in the state of Mexico

Introduction: Concern for improving the health conditions of women and pregnant women as critical points, to improve the health of neonates, had already been previously analyzed. However, we observe that a series of factors continue to strongly influence the health systems of our country. Within these observations, it is detected that pregnant women still have failures in some of the critical links of care, despite the fact that strategies were suggested to improve opportunities for improvement in the field of care for women and women. Pregnant, for reproductive health. In order to positively impact and reduce neonatal death as well as neurological damage in newborns. In previous analyzes it was possible to verify that by detecting these opportunities for improvement in the obstetric care process, new strategies were found each time to avoid factors that seriously impact the health of neonates. Objective: To monitor the current state of neonatal death taking into account a time line in a previously monitored population, trying to detect preventive actions, to specifically protect the newborn; Positively impacting maternal health. Method: Analysis of clinical records of 310 deaths of newborns was carried out according to the recommendations of Dr. Brown in Georgia, who assigned a percentage of responsibility basically in 4 areas, namely: 1.-Health of the woman to whom he gave a very high weight 60% responsibility. 2.- Maternal care with 10% responsibility. 3.- Neonatal Care, 9% responsibility, and 4.- Postnatal Care, 21%. The method includes color coding: #1 Brown; #2, Network; #3, Green; and #4 Lila, respectively for each area mentioned; which are expressed in a table to be able to contain data from each patient and thereby identify the area of responsibilities to convert it into an area of Opportunity. Once the number of Neonatal deaths for the 2010-2015 period was analyzed, the results were compared with previous periods, previously analyzed, to measure whether there are new factors that require new approach strategies. Results: In the period 203-206, basically three pathologies responsible for the death: 61% Prematurity, 25% sepsis, 61.7% asphyxia, and according to the color code entered the area of responsibility for obstetric care. In the years 2007-2008: there was an increase in Prematurity to 66.6%; there was a decrease in sepsis to 14%. And decrease in babies under 1500gr. to 46.6%, after applying initial analysis strategies. (3) In the 2010-2015 period, premature babies fell to 63%; Asphyxia decreased 38% and sepsis remained at 14%, Babies under 1500gr increased to 57.7% Conclusions: We can see that the risk factors for neonatal death remained present, but we noticed a significant decrease compared to previous periods, according to the analysis of the Dr. Brown method, it translates into an area of opportunity for improvement with high weight for the area of obstetric care, we can comment that newborns within the Neonatal area of responsibility were registered once they were received very serious from birth and after neonatal intensive care, by age they entered that area of responsibility. Also to clarify that the asphyxia patients, in 98% of the cases were intrauterine. Permanent monitoring is urgently needed, and there is an insistence on applying a 4x4 team building strategy in the field of women's and pregnant women's health Permanent monitoring is urgent, and there is an insistence on applying a 4x4 team formation strategy in the field of women's and pregnant women's health (Based Colaborating Centered in Reproductive Health The National Centers For Disease Control and Prevention Georgia Department of Human Resource)

Triptychon: Usability evaluation and implementation of a web-based application for patients' lab and vital parameters.

A major challenge in healthcare is the interpretation of the constantly increasing amount of clinical data of interest to inpatients for diagnosis and therapy. It is vital to accurately structure and represent data from different sources to help clinicians make informed decisions. We evaluated the usability of our tool 'Triptychon' - a three-part visualisation dashboard of essential patients' medical data provided by a direct overview of their hospitalisation information, laboratory, and vital parameters over time. The study followed a cohort of 20 participants using the mixed-methods approach, including interviews and the usability questionnaires, Health Information Technology Usability Evaluation Scale (Health-ITUES), and User Experience Questionnaire (UEQ). The participant's interactions with the dashboard were also observed. A thematic analysis approach was applied to analyse qualitative data and the quantitative data's task completion time and success rates. The usability evaluation of the visualisation dashboard revealed issues relating to the terminology used in the user interface and colour coding in its left and middle panels. The Health-ITUES score was 3.72 (standard deviation (SD) = 1.0), and the UEQ score was 1.6 (SD = 0.74). The study demonstrated improvements in intuitive dashboard use and overall satisfaction with using the dashboard daily. The Triptychon dashboard is a promising new tool for medical data presentation. We identified design and layout issues of the dashboard for improving its usability in routine clinical practice. According to users' feedback, the three panels on the dashboard provided a holistic view of a patient's hospital stay.
