Authors: Kohan M.
Published: May 2023

Abstract. The aim of the work is to determine suitable settings of filament production parameters for medical applications from materials PEEK and PPSU alone, as well as with a 10wt% of the ceramic components Hydroxyapatite (HA) and Tricalcium Phosphate (TCP) admixture. Filaments were made using the Filament Maker machine (3devo, The Netherlands). The filaments were manufactured according to the requirements for usage in the FDM technology with a nominal diameter of 1.75 mm. The diameter of the filaments was measured with an optical sensor and analyzed using DevoVision software (3devo, The Netherlands). The analysis of the filament diameters was carried out using descriptive statistics in order to determine quality of the filaments. The analysis of the produced filament diameter from the materials PEEK, PEEK + HA/ TCP , PPSU and PPSU + HA/ TCP demonstrated that the measured values of the diameters of the filaments from the nominal value (1.75 mm) showed minimal deviations, as well as the fact that the limit values were not exceeded (1.85 mm; 1.65 mm) and thus it is possible to state that the manufactured filaments meet the required quality for use in FDM technology. A microscopic analysis was also carried out on the manufactured filaments in order to determine the distribution of the ceramic component in the manufactured filaments. An Olympus GX71 inverted metallographic microscope with an Olympus DP12 camera was used for the purpose of expertise. The total number of examined samples was n = 40, while 10 samples from each filament were selected from random areas. Microscopic analysis of the produced filaments showed a uniform distribution of the ceramic component in the composite filaments, which means that the manufacturing process does not affect the distribution of the ceramic component in the filament.

Authors: Kurniawan Ardhi
Published: May 2023

Local Economic Development (LED) is an appropriate development concept due to the related local or territorial circumstances like considering locality capacity, internal and external factors, and local economic growth so that it has been implemented in many countries. Then the existence of village autonomy and rural area development in Indonesia is such a form of LED implementation. Generally, LED implementation through rural area development has not been successful enough, but in some districts, it has not provided a big impact to improve the people's prosperity. To succeed the LED implementation in developing rural areas, it requires strategies to tackle some problems and challenges and provides a vivid goal in the long term so that the development conducted can synergize each other. Scenario planning is one of the relevant approaches in this case since it accommodates the high complexity and uncertainty. Also, it is used in long-term planning formulation. Moreover, this scenario planning used the TAID method that is tracking, analyzing, imaging, and deciding. Data in this research are compiled by interview, secondary data, and observation to meet the tracking step. Then the output of this will be analyzed using cross-impact to create a scenario in the analyzing step, and the output will be an input for formulating visions and strategies in the imaging and deciding step. This article provides four alternative strategies for developing rural areas which are Dissemination, Optimization, Affirmation, and Reformation.

Joint Analysis of the Epidemic Evolution and Human Mobility During the First Wave of COVID-19 in Spain: Retrospective Study
Authors: Steinegger Benjamin , Granell Clara , Rapisardi Giacomo , Gómez Sergio , Matamalas Joan , Soriano-Paños David , Gómez-Gardeñes Jesús , Arenas Alex
Published: May 2023

Background

The initial wave of the COVID-19 pandemic placed a tremendous strain on health care systems worldwide. To mitigate the spread of the virus, many countries implemented stringent nonpharmaceutical interventions (NPIs), which significantly altered human behavior both before and after their enactment. Despite these efforts, a precise assessment of the impact and efficacy of these NPIs, as well as the extent of human behavioral changes, remained elusive.

Objective

In this study, we conducted a retrospective analysis of the initial wave of COVID-19 in Spain to better comprehend the influence of NPIs and their interaction with human behavior. Such investigations are vital for devising future mitigation strategies to combat COVID-19 and enhance epidemic preparedness more broadly.

Methods

We used a combination of national and regional retrospective analyses of pandemic incidence alongside large-scale mobility data to assess the impact and timing of government-implemented NPIs in combating COVID-19. Additionally, we compared these findings with a model-based inference of hospitalizations and fatalities. This model-based approach enabled us to construct counterfactual scenarios that gauged the consequences of delayed initiation of epidemic response measures.

Results

Our analysis demonstrated that the pre–national lockdown epidemic response, encompassing regional measures and heightened individual awareness, significantly contributed to reducing the disease burden in Spain. The mobility data indicated that people adjusted their behavior in response to the regional epidemiological situation before the nationwide lockdown was implemented. Counterfactual scenarios suggested that without this early epidemic response, there would have been an estimated 45,400 (95% CI 37,400-58,000) fatalities and 182,600 (95% CI 150,400-233,800) hospitalizations compared to the reported figures of 27,800 fatalities and 107,600 hospitalizations, respectively.

Conclusions

Our findings underscore the significance of self-implemented prevention measures by the population and regional NPIs before the national lockdown in Spain. The study also emphasizes the necessity for prompt and precise data quantification prior to enacting enforced measures. This highlights the critical interplay between NPIs, epidemic progression, and human behavior. This interdependence presents a challenge in predicting the impact of NPIs before they are implemented.

Authors: Amore Alexis Dunn , Britt Abby , Arconada Alvarez Santiago J , Greenleaf Morgan N
Published: May 2023

Background

Maternal mortality in the United States is a public health crisis and national emergency. Missed or delayed recognition of preventable life-threatening symptoms and untimely treatment of preventable high-risk medical conditions have been cited as key contributors to the nation’s worsening mortality rates. Effective strategies are urgently needed to address this maternal health crisis, particularly for Black birthing populations. Morbidity and Mortality Assessment: Lifting Outcomes Via Education (MAMA LOVE) is a web-based platform that focuses on the identification of maternal morbidity and mortality risk factors.

Objective

The purpose of this paper is to present the conceptualization, development, heuristics, and utility evaluation of the web-based maternal mortality risk assessment and educational tool MAMA LOVE.

Methods

A user-centered design approach was used to gain feedback from clinical experts and potential end users to ensure that the tool would be effective among groups most at risk for maternal morbidity and mortality. A heuristic evaluation was conducted to evaluate usability and need within the current market. Algorithms describing key clinical, mental health, and social conditions were designed using digital canvas software (Miro) and incorporated into the final wireframes of the revised prototype. The completed version of MAMA LOVE was designed in Figma and built with the SurveyJS platform.

Results

The creation of the MAMA LOVE tool followed three distinct phases: (1) the content development and creation of an initial prototype; (2) the feedback gathering and usability assessment of the prototype; and (3) the design, development, and testing of the final tool. The tool determines the corresponding course of action using the algorithm developed by the authors. A total of 38 issues were found in the heuristic evaluation of the web tool’s initial prototype.

Conclusions

Maternal morbidity and mortality is a public health crisis needing immediate effective interventions. In the current market, there are few digital resources available that focus specifically on the identification of dangerous symptoms and risk factors. MAMA LOVE is a tool that can address that need by increasing knowledge and providing resources and information that can be shared with health care professionals.

Authors: Liman Leon , May Bernd , Fette Georg , Krebs Jonathan , Puppe Frank
Published: May 2023

BACKGROUND

Due to the importance of radiologic examinations, such as X-rays or computed tomography scans, for many clinical diagnoses, the optimal use of the radiology department is 1 of the primary goals of many hospitals.

OBJECTIVE

This study aims to calculate the key metrics of this use by creating a radiology data warehouse solution, where data from radiology information systems (RISs) can be imported and then queried using a query language as well as a graphical user interface (GUI).

METHODS

Using a simple configuration file, the developed system allowed for the processing of radiology data exported from any kind of RIS into a Microsoft Excel, comma-separated value (CSV), or JavaScript Object Notation (JSON) file. These data were then imported into a clinical data warehouse. Additional values based on the radiology data were calculated during this import process by implementing 1 of several provided interfaces. Afterward, the query language and GUI of the data warehouse were used to configure and calculate reports on these data. For the most common types of requested reports, a web interface was created to view their numbers as graphics.

RESULTS

The tool was successfully tested with the data of 4 different German hospitals from 2018 to 2021, with a total of 1,436,111 examinations. The user feedback was good, since all their queries could be answered if the available data were sufficient. The initial processing of the radiology data for using them with the clinical data warehouse took (depending on the amount of data provided by each hospital) between 7 minutes and 1 hour 11 minutes. Calculating 3 reports of different complexities on the data of each hospital was possible in 1-3 seconds for reports with up to 200 individual calculations and in up to 1.5 minutes for reports with up to 8200 individual calculations.

CONCLUSIONS

A system was developed with the main advantage of being generic concerning the export of different RISs as well as concerning the configuration of queries for various reports. The queries could be configured easily using the GUI of the data warehouse, and their results could be exported into the standard formats Excel and CSV for further processing.
A New Imbalance and Falling Perception (IFP) Algorithm Design for Elderly Fallproof (Preprint)
Authors: Yao Chong , Huang Anpeng , Huangqi Chonghui
Published: May 2023

BACKGROUND

According to WHO report, approximately 28-35% of people aged 65 or over are injured in fall events each year.

OBJECTIVE

To take advantage of mobile health (mHealth) technologies, it is significant to design a fall detection algorithm for alerting and preventing elderly falling events.

METHODS

For this purpose, a new Imbalance and Falling Perception (IFP) algorithm is designed, which can distinguish imbalance risks from falling events. In real applications, noise and interference from the training samples can be filtered out by using a data monitoring pattern, which can separate sensory data from non-purpose motion behaviors, such as crouch actions.

RESULTS

In this proposal, relevant features are evaluated and selected from raw data by using Term Frequency–Inverse Document Frequency (TF-IDF) and Bag-of-Word (BoD) methods, which can obtain lower computing complexity, and scale down data load effectively. In return, this favorite feature can provide users’ devices with quicker CPU response and long battery life.

CONCLUSIONS

System tests and clinical trials demonstrate that recognition precision and recall rates can reach 96% and 92%, respectively. All these gains can make the proposal very suitable for elderly daily falling events monitoring.

Published: May 2023

UNSTRUCTURED

Primary care services are appealing an increasing attention in integrated and person-centered health care in many countries. Active involving patients and communities in health decisions can improve both people’s health and the healthcare system. Adopting artificial intelligence can lead to more accurate and complete patient record management. This review aims to identify the current state of researches conducted using artificial intelligence techniques to improve patient engagement and wellbeing, medical domains used in patient engagement context and lastly to assess opportunities and challenges for patient engagement in the wellness process.
A search of peer-reviewed publications, reviews, conceptual analyses, white papers, author’s manuscripts and theses was undertaken. English language literature published in 2013– 2022 period and publications, report and guidelines of World Health Organization (WHO) were also assessed. About 281 papers were retrieved. Duplicate papers in the databases were removed. After application of the inclusion and exclusion criteria, 41 papers were included to the analysis. Patient counseling in preventing adverse drug events, in doctor-patient risk communication, surgical, drug development, mental healthcare, hypertension & diabetes, metabolic syndrome and non-communicable chronic diseases are implementation areas in healthcare where patient engagement can be implemented using artificial intelligence, particularly, machine learning and deep learning techniques and tools. The five groups of factors that potentially affecting patient engagement in safety are related to: patient, health conditions, health care professionals, tasks and health care setting. Active involvement of patients and families can help accelerate the implementation of healthcare safety initiatives. In sub-Saharan Africa, using digital technologies like artificial intelligence in patient engagement context is low due to poor level of technological development and deployment. The opportunities and challenges available to implement patient engagement strategies vary greatly from country to country and from region to region. Thus, further investigation will be focused on methods and tools using the potential of artificial intelligence to support more simplified care that might be improve communication with patients and train health care professionals.

Published: May 2023

BACKGROUND

Mobility challenges, transportation, and finances may serve as barriers to diabetic retinopathy (DR) screening in the growing elderly population in Ontario. Screening of patients in their own nursing homes using teleophthalmology may improve accessibility to DR screening.

OBJECTIVE

To report the feasibility, results, and patient satisfaction of a pilot expansion of the Toronto Tele-Retinal Screening Program in an elderly long-term care home.

METHODS

A pilot project was initiated with a cohort of elderly patients with Type II diabetes mellitus (DM) in long-term care who were referred to the Toronto Tele-Retinal Screening Program for DR screening between April 1, 2022 and July 1, 2022.

RESULTS

A total of 28 patients were screened for DR. Half (14/28) of patients suffered from a fall within the last year and 35% (10/28) were fully dependent for mobility. Overall, 14.3% (4/28) of patients could not be successfully imaged. Of the patients imaged, 8.3% (2/24) were advised to arrange an urgent follow-up. Pathologies identified included uncontrolled glaucoma (4.1%, 1/24), non-proliferative DR (NPDR) (8.3%, 2/24), wet age-related macular degeneration (AMD) (8.3%, 2/24), and dry AMD (37.5%, 9/24). A total of 20.8% (5/24) patients could not undergo tabletop imaging due to mobility issues. Screening of 60% (3/5) of these patients were successful with the handheld camera. Overall, 90% (17/19) of patients rated their subjective screening experience as either “brilliant” or “really good.”

CONCLUSIONS

This pilot project demonstrated that the implementation of the Toronto Tele-Retinal Screening Program into elderly long-term care homes may mitigate common barriers to eye screening with a good subjective patient experience.

Line losses reduction greatly affects the performance of the electric distribution network. This paper aims to identify the influencing factors causing power losses in that network. Newton-Raphson method is used for the loss assessment and the Sensitivity analysis by approach One-Factor-At-A-Time (OAT) for the influencing factors identification. Simulation with the meshed IEEE-30 bus test system is carried out under MATLAB environment. Among the 14 parameters investigated of each line, the result shows that the consumed reactive powers by loads, the bus voltages and the linear parameters are the most influencing on the power losses in several lines. Thus, in order to optimize these losses, the solution consists of the reactive power compensation by using capacitor banks; then the placement of appropriate components in the network according to the corresponding loads; and finally, the injection of other energy sources into the bus which recorded high level losses by using the hybrid system for instance.

Published: May 2023

Abstract: The lateral-torsional buckling behavior of I-beams with web openings has been a topic of interest among structural engineers for many years. The presence of a web opening in the beam can significantly affect its strength and stiffness, making it more prone to buckling failure. Therefore, understanding the buckling behavior of I-beams with web openings is crucial for the design of steel structures. Finite Element Analysis (FEA) has become a widely used tool for investigating the behavior of structures under different loading conditions. In this study, FEA was used to analyze the lateral-torsional buckling behavior of I-beams with web openings. The software used for the analysis was ETABS, which is a widely used software for analyzing and designing buildings and other structures. The objective of the study was to investigate the effects of different web opening shapes, sizes, and locations on the buckling strength of the beam. The FEA simulations were validated using experimental data available in the literature. The study analyzed different types of web openings, such as circular, rectangular, and elliptical shapes, and various sizes and locations of the web opening along the beam span. The results of the study showed that the presence of a web opening significantly reduced the strength and stiffness of the I-beam, making it more susceptible to buckling failure. The location of the web opening had a more significant effect on the buckling behavior than its size and shape. The results of the FEA simulations were found to be in good agreement with the experimental data available in the literature, which validates the accuracy of the ETABS software in predicting the buckling behavior of I-beams with web openings
Obstacle and Collision Avoiding Drone
Authors: S Ravi Kumar , N Srihith D. L. , K Jayanth Kumar , S Bhaskar Pradeep
Published: May 2023

Abstract: Larger drones, such as those used for commercial operations, are much less likely to have obstacle avoidance features because they fly higher in the sky, where it is less likely that they will encounter static obstacles and more likely that they will encounter dynamic obstacles while also flying faster; the market’s offerings for static obstacle avoidance do not meet those needs. Since smaller drones are typically used for hobbyists and smaller-scale operations like thermal inspection, hazard detection inside of warehouses, and up-close inspection of wind turbines and power lines, obstacle avoidance is typically limited to these types of smaller drones. The performance requirements for Detect-and-Avoid capabilities for dynamic objects vary since infrastructure masking can occasionally reduce risks. For instance, you have an additional layer of protection when flying near structures or in a deep valley because manned aviation is less likely to be using the same airspace. Similar to this, infrastructure shadowing involves flying 50 feet or less away from a power line that is exactly 50 feet above the structure being “shadowed.” Given that you are more unlikely to come across any manned aircraft, this mitigation level is higher than just masking.

We introduce a classical algorithm to approximate the free energy of local, translation-invariant, one-dimensional quantum systems in the thermodynamic limit of infinite chain size. While the ground state problem (i.e., the free energy at temperatureT=0) for these systems is expected to be computationally hard even for quantum computers, our algorithm runs for any fixed temperatureT>0in subpolynomial time, i.e., in timeO((1ε)c)for any constantc>0whereεis the additive approximation error. Previously, the best known algorithm had a runtime that is polynomial in1ε. Our algorithm is also particularly simple as it reduces to the computation of the spectral radius of a linear map. This linear map has an interpretation as a noncommutative transfer matrix and has been studied previously to prove results on the analyticity of the free energy and the decay of correlations. We also show that the corresponding eigenvector of this map gives an approximation of the marginal of the Gibbs state and thereby allows for the computation of various thermodynamic properties of the quantum system.

Aim: to present the value of interventional radiology techniques in the treatment of a patient with liver metastasis of colorectal cancer.

Key points. In 2013, a 60-year-old patient with stage IIIB sigmoid colon cancer, pT3N2M0 underwent resection of the sigmoid colon with the formation of hardware rectosigmoanastomosis, 6 courses of adjuvant chemotherapy were performed. In 2015, a control examination revealed metastatic liver damage. Liver resection could not be performed due to the small future residual volume, and systemic chemotherapy was not effective. The patient underwent 3 cycles of regional chemotherapy. Taking into account the pronounced positive dynamics, in the form of a decrease in tumor size and a decrease in cancer markers, the patient managed to perform an extended right-sided hemihepatectomy. No progression of the tumor process was detected during the follow-up.

Conclusion. Modern possibilities of X-ray endovascular methods allow to achieve results in the treatment of patients with colorectal cancer metastases in the liver such as a decrease in metastases in size, that make liver resection possible.
Playing the Electrophonic Saxophone
Authors: Kjetil Traavik Møster
Published: May 2023

'Playing the Electrophonic Saxophone' explores the expanded role of the instrument and relations made possible by such expansions. In and through artistic practice I research the many processes, tensions, and artistic possibilities that emerge through interplay. How can exploring possibilities and conditions for the acoustic saxophone in interplay with electric and electronic tools and sounds pave the way for new music, new insights, and expand the conception of what the instrument can be? How can playing with electrically and digitally manipulated sound facilitate the instrument’s ability to connect to musicians and artists from other fields of practice? The research’s main artistic outcome is the sum of a series of artistic projects presented in this exposition. The two texts Playing Air and Playing Parasitic constitute the ethical and methodological basis for the research and my practice and transfers to the projects’ two basic elements: roles and their relations. The band Møster! acts as the main project ensemble, and the PhD research is finalized with a public artistic presentation at the Nattjazz Festival, Røkeriet USF, Bergen on June 1st, 2021.

'Playing the Electrophonic Saxophone' utforsker instrumentets utvidete rolle, og relasjoner som en slik utvidelse åpner for. I og gjennom kunstnerisk praksis forsker jeg på de mange prosesser, spenninger, og kunstneriske potensial som vokser frem gjennom samspill. Hvordan kan utforskning av muligheter og premisser for akustisk saksofonspill i samspill med elektriske og elektroniske verktøy og lyder lede til ny musikk, ny innsikt, og utvide forståelsen av hva instrumentet kan være? Hvordan kan det å spille med elektrisk og digitalt manipulert lyd legge til rette for samhandling med musikere og artister fra andre kunstneriske felt, med ulike kunstneriske praksiser? Forskningens kunstneriske resultat er presentert som en samling prosjekter i denne eksposisjonen. De to tekstene 'Playing Air' og 'Playing Parasitic' utgjør det metodologiske og etiske grunnlaget for forskningen og min praksis, og kan leses inn i forskningens to hovedelementer: roller, og deres relasjoner. Bandet Møster! fungerer som hoved-ensemble, og PhD-prosjektet ble avsluttet med en offentlig konsertfremføring på Nattjazz, Røkeriet USF i Bergen, 1. juni 2021.

Open Form. An Expanded Performer´s Role.
Authors: Else Olsen Storesund
Published: May 2023

Open form is a designation on a type of composition that is in some degree open. It is also a term in relation to understanding a genre. This means that I do not include for example Bach´s Die Kunst der Fuge (circa 1740), but Stockhausen´s Aus den sieben Tagen (1968) could be included. This project, however, is centered around the composers from The New York Scool, and composers related to The New York School: Christian Wolff, Pauline Oliveros, John Cage, Earle Brown, Morton Feldman and Cornelius Cardew.
An Open form composition is graphic, text- or number-based. It may also be a combination of these three notational techniques and/or in combination with conventional staff line-notation.
Beyond black and white
Authors: Bernard Lanskey  , Stephen Emmerson  , Bernard Lanskey
Published: May 2023

This exposition reflects on several performances by the authors that aimed to re-imagine selected
pieces by Debussy in the centenary year of his death. More particularly, it considers some issues and
implications arising from performing the composer’s music for piano(s) on modern digital
instruments, specifically the Nord Stage 3 keyboards (2017). The exposition focuses primarily on the
second movement of En blanc et noir, although the composer’s version of Prélude à l'après-midi d'un
faune for two pianos and the solo prelude “Voiles” are also considered. The authors propose that
exploring this pivotal music from the Western and Modernist traditions on digital instruments allows
it to be presented and heard in new ways, thereby expanding our perception and experience of it.
Several video-recorded performances of these pieces are provided. An outline of Debussy’s own
preferences concerning instruments is offered, together with some brief comments on his broader
aesthetics, our perspective being that our versions remain congruent with underlying aspects of
both of these.
Composing Together and Not Together - Intimacy as a Condition for Collaboration
Authors: Josh Spear
Published: May 2023

Collaborative creative processes within the realm of Western Art Music are usually hidden and/or not actually collaborative at all. Vera John-Steiner (2000) defines ‘integrative collaboration’ as a working situation in which roles merge and a shared ideology and vision emerge through dialogue.

This artistic research project investigates to what extent intimacy is a condition for collaboration and what it means within music-making. Intimacy is newly defined as the play of affective, physical and emotional borders between people where our own sense of ourselves can be shaped.

By considering collaborative working as a compositional tool, intimacy becomes something that can be encouraged, indeed collaborative skills can be practiced. Through a variety of music-making projects in which I am project lead, composer and/or performer or composer-performer, I devise strategies for handing over power to my colleagues and harnessing their creativity such that they become co-creators rather than just interpreters. I investigate different approaches to intimacy within the domains of music and theatre. I also reflect on my own development as a collaborator and attempt to create a set of principles for successful collaborative working.

A set of advantages to adopting a devised process have emerged and a new focus on the long-term potential of a group or partnership changes the context for collaboration. Understanding that a creative partnership is a tree and artistic products are the fruits of that tree has caused me to understand collaboration as multimodal, beyond the score, and made clear the options for the choices of values within collaboration.
EXTENDED COMPOSITION

Published: May 2023

In the sphere of contemporary composition and performance, the material for composers and musicians is not only sound, but extends to different forms of visuality, objects, movements and language. The Extended Composition project poses some fundamental questions: what new strategies for composition and performance will have to be developed to master the multitude of sign systems emergent from music’s expanded material array? What new significance is emerging from the layers in an extended composition of sound, language and movements, and how do we evaluate it? This presentation contains reflections and presentations of three artistic works done in collaboration between composers, musicians, dancers and other artists. The project group has been Henrik Hellstenius, Tanja Orning, Christian Blom, Ellen Ugelvik and Camilla Eeg-Tverbakk.
