Published: September 2023

Coronaviruses have affected the lives of people around the world. Increasingly, studies have indicated that the virus is mutating and becoming more contagious. Hence, the pressing priority is to swiftly and accurately predict patient outcomes. In addition, physicians and patients increasingly need interpretability when building machine models in healthcare. We propose an interpretable machine framework(KISM) that can diagnose and prognose patients based on blood test datasets. First, we use k-nearest neighbors, isolated forests, and SMOTE to pre-process the original blood test datasets. Seven machine learning tools Support Vector Machine, Extra Tree, Random Forest, Gradient Boosting Decision Tree, eXtreme Gradient Boosting, Logistic Regression, and ensemble learning were then used to diagnose and predict COVID-19. In addition, we used SHAP and scikit-learn post-hoc interpretability to report feature importance, allowing healthcare professionals and artificial intelligence models to interact to suggest biomarkers that some doctors may have missed. The 10-fold cross-validation of two public datasets shows that the performance of KISM is better than that of the current state-of-the-art methods. In the diagnostic COVID-19 task, an AUC value of 0.9869 and an accuracy of 0.9787 were obtained, and ultimately Leukocytes, platelets, and Proteina C reativa mg/dL were found to be the most indicative biomarkers for the diagnosis of COVID-19. An AUC value of 0.9949 and an accuracy of 0.9677 were obtained in the prognostic COVID-19 task and Age, LYMPH, and WBC were found to be the most indicative biomarkers for identifying the severity of the patient.

Background

In Australia, the distribution of occupational therapists, physiotherapists, and podiatrists density (per 10,000 population) by measure of location/rurality, usual resident population, and area-level socioeconomic status has not been described.

Objective

To describe the national as well as states-and territories-wide distribution of registered allied health workforce—occupational therapists, physiotherapists, and podiatrists—by measures of rurality and area-level socioeconomic position in Australia.

Methods

A linked data study that brings together (1) the location of health practitioners’ principal place of practice from the Australian Health Practitioner Regulation Agency, (2) a measure of location/rurality—Modified Monash Model (MMM), and (3) an area-level measure of socioeconomic status—Index of Relative Socio-Economic Advantage and Disadvantage (IRSAD). The provider-to-population ratio (i.e., density) of three Australia’s allied health workforce (occupational therapists, physiotherapists, and podiatrists) was calculated according to the MMM classifications (i.e., Modified Monash 1–7) and IRSAD quintiles at state and national level.

Results

Nationwide, the density of occupational therapists and physiotherapists was highest in metropolitan areas (Modified Monash 1) and decreased with the increasing levels of the MMM categories. The national density of podiatrists was highest in Modified Monash 3 areas. The density of occupational therapists, physiotherapists, and podiatrists was highest in areas with IRSAD quintile 5 (i.e., the highest socioeconomic position) and decreased with the declining levels of the IRSAD quintiles nationwide. Moreover, there were notable disparities in the density of occupational therapists, physiotherapists, and podiatrists across each state and territory in Australia when stratified by the MMM classifications and IRSAD quintiles.

Conclusions

There was uneven distribution of registered occupational therapists, physiotherapists, and podiatrists when stratified by measures of location/rurality and area-level socioeconomic status across Australian jurisdictions. The density of these three groups of allied health workforce tended to be more concentrated in metropolitan and most advantaged areas while remote and most disadvantaged areas exhibited less allied health workforce distribution across each state and territory.
Spätzle processing enzyme is required to activate dorsal switch protein 1 induced Toll immune signalling pathway in Tenebrio molitor
Authors: Mollah Md. Mahi Imam
Published: September 2023

Dorsal switch protein 1 (DSP1) acts as a damage-associated molecular pattern (DAMP) molecule to activate immune responses inTenebrio molitor. From a previous study inSpodoptera exigua, we found that DSP1 activates Toll immune signalling pathway to induce immune responses by melanisation, PLA2activity and AMP synthesis. However, the target site of DSP1 in this pathway remains unknown. The objective of this study was to determine the role of spätzle processing enzyme in the DSP1 induced toll immune signalling pathway. To address this, we analyzed spätzle processing enzyme (Tm-SPE) of the three-step serine protease cascade ofT.molitorToll pathway.Tm-SPEexpressed in all developmental stages and larval tissues. Upon immune challenge, its expression levels were upregulated but significantly reduced after RNA interference (RNAi). In addition, the induction of immune responses upon immune challenge or recombinant DSP1 injection was significantly increased. Loss of function using RNA interference revealed that theTm-SPEis involved in connecting DSP1 induced immune responses like hemocyte nodule formation, phenoloxidase (PO) activity, phospholipase A2(PLA2) activity and antimicrobial peptide (AMP) synthesis. These suggest thatTm-SPEcontrols the DSP1 induced activation of Toll immune signalling pathway required for both cellular and humoral immune responses. However, to confirm the target molecule of DSP1 in three-step proteolytic cascade, we have to check other upstream serine proteases like Spatzle activating enzyme (SAE) or modular serine protease (MSP).

Published: September 2023

In freshwaters, microbial communities are of outstanding importance both from ecological and public health perspectives, however, they are threatened by the impact of global warming. To reveal how different prokaryotic communities in a large temperate river respond to environment conditions related to climate change, the present study provides the first detailed insight into the composition and spatial and year-round temporal variations of planktonic and epilithic prokaryotic community. Microbial diversity was studied using high-throughput next generation amplicon sequencing. Sampling was carried out monthly in the midstream and the littoral zone of the Danube, upstream and downstream from a large urban area. Result demonstrated that river habitats predominantly determine the taxonomic composition of the microbiota; diverse and well-differentiated microbial communities developed in water and epilithon, with higher variance in the latter. The composition of bacterioplankton clearly followed the prolongation of the summer resulting from climate change, while the epilithon community was less responsive. Rising water temperatures was associated with increased abundances of many taxa (such as phylum Actinobacteria, class Gammaproteobacteria and orders Synechococcales, Alteromonadales, Chitinophagales, Pseudomonadales, Rhizobiales and Xanthomonadales), and the composition of the microbiota also reflected changes of several further environmental factors (such as turbidity, TOC, electric conductivity, pH and the concentration of phosphate, sulphate, nitrate, total nitrogen and the dissolved oxygen). The results indicate that shift in microbial community responding to changing environment may be of crucial importance in the decomposition of organic compounds (including pollutants and xenobiotics), the transformation and accumulation of heavy metals and the occurrence of pathogens or antimicrobial resistant organisms.

Authors:   Crisis and Emergency Management: Theory and Praxis, Lee Jae Eun
Published: September 2023

The purpose of this study is to suggest a community disaster resilience model to become a sustainable society in the era of climate crisis. The climate crisis not only has a direct impact on human life, but also has a wide and severe impact on various environments surrounding humans. In fact, all spheres that make up or surround a community are affected. For example, all areas such as politics, economy, society, culture, nature, science and technology, medical health, military, and safety of a country or region are being forced to change by the climate crisis. If we refuse to change due to the climate crisis or do not accept a new paradigm, the very survival of human society will be threatened. In order to secure community disaster resilience, it is necessary to improve resilience at individual, community, and environmental levels. Efforts should be made to improve good health (psychological & physical health), quality familyship, and financial stability at the individual level. At the community level, economic growth, social capital, and cultural inclusion, and at the environmental level, infrastructure recovery, government function, and nature restoration.

Authors:   Crisis and Emergency Management: Theory and Praxis, Yim Dong Kyun
Published: September 2023

Since the establishment of the government, large-scale safety accidents have continued to occur and human and material damage has increased. The responsibility is not only the responsibility of some specific organizations such as the state or local governments. In order to prevent such accidents, not only the nation but also the people should be interested in safety education, protect themselves, and feel a sense of responsibility for safety in a social sense. Safety education should naturally permeate into daily life. However, it is also true that there is still a public opinion that recognizes the efforts and costs of safety education as an economic burden. Therefore, by activating the safety experience center, it is necessary to correct the unreasonable perception of accumulated safety throughout the nation and society so that the people can enjoy a safe and comfortable life. In this study, the activation plan of the safety experience center was examined using FGI survey and AHP analysis technique to activate the safety experience center.

Knowing the phenology and phyllochron of strawberry cultivars allows the establishment of phytotechnical managements aimed at enhancing the productive chain of this horticultural crop. Thus, the objective of this work was to investigate whether phenology and phyllochron differ among strawberry cultivars grown in substrate and greenhouse. The treatments were seven strawberry cultivars arranged in a randomized block design, with four replications. Leaf emission rate, occurrence and duration of phenological stages were evaluated. ‘Fronteras’ was considered the earliest to start fruiting, as it had the lowest phyllochron value, while ‘Albion’ was the latest. Through multivariate analysis, the formation of two groups among strawberry cultivars was observed according to their phenological characteristics. Group 1 gathered the five strawberry cultivars classified as having neutral-days in terms of flowering and group 2 was composed of the two short-day cultivars. It is concluded that, under the cultivation conditions of southern Brazil, ‘Fronteras’ is the earliest to start the fruit harvest, provided it is transplanted in May, and ‘Albion’ is the latest. Neutral-day cultivars have a shorter transplant cycle until the beginning of harvest, while short-day cultivars require a longer interval for this transition, with a prolonged vegetative period.

Published: September 2023

INTRODUCTION:

Osteoporosis in candidates for liver transplantation (LT) is often underdiagnosed despite the important consequences of morbidity.

METHODS:

We included 376 patients with cirrhosis evaluated for LT with available computed tomography (CT) scans. Prevalent vertebral fractures (VFs) were identified on CT reconstructions, and bone density was assessed by measuring CT attenuation of the L1 vertebra (L1-CT).

RESULTS:

We identified 139 VFs in 55 patients (14.6%). Logistic regression models showed that low L1-CT was the only independent determinant of VF.

DISCUSSION:

In patients with cirrhosis evaluated for LT, CT scans identified persons with severe osteoporosis without additional costs.

INTRODUCTION:

When initial resection of rectal neuroendocrine tumors (r-NETs) is not R0, persistence of local residue could lead to disease recurrence. This study aimed to evaluate the interest of systematic resection of non-R0 r-NET scars.

METHODS:

Retrospective analysis of all the consecutive endoscopic revisions and resections of the scar after non-R0 resections of r-NETs.

RESULTS:

A total of 100 patients were included. Salvage endoscopic procedure using endoscopic submucosal dissection or endoscopic full-thickness resection showed an R0 rate of near 100%. Residual r-NET was found in 43% of cases.

DISCUSSION:

In case of non-R0 resected r-NET, systematic scar resection by endoscopic full-thickness resection or endoscopic submucosal dissection seems necessary.

Published: September 2023

This research focuses on investigating the mechanical properties of polyurethane foam, specifically in the context of the refrigeration industry. Tensile, compression, and flexural tests were conducted to gather comprehensive data on the foam's mechanical behavior under various loading conditions. Samples were collected from different regions within a specific cabinet model to analyze the effects of region and direction of the foam growth on the foam's mechanical properties. The results revealed that samples collected from the top of the cabinet exhibited superior performance compared to those obtained from the bottom. The foam demonstrated isotropic behavior under compression, while exhibiting anisotropic behavior under tensile and flexure. When aligned parallel to the foam growth, the foam displayed slightly higher maximum stress in the tensile and flexural tests. However, the compression test showed comparable strength in both directions. These findings contribute to a better understanding and utilization of PU foam in various industrial sectors, particularly in refrigeration. The data obtained from this research can support the optimization of project designs and facilitate the development of more efficient and economically viable solutions.

Background: During the COVID-19 pandemic, new policies were established to decrease the transmission of infection. These changes in policies might have an impact on health promoting activities and social support among adolescents. Purpose: The purpose of this study was to describe the levels of health promoting activities and social support among adolescents. Methods: A descriptive cross-sectional design was applied to collect data from 298 Jordanian adolescents. Results: Females reported a significantly higher mean score than males in total AHPS, peer support, health responsibility, life appreciation, and stress management. Male adolescents scored a significantly higher mean score in physical activity. The averages of peer support and family support were significantly higher among adolescents from private schools. Adolescents aged from 10 to 13 years scored a significantly higher average of nutrition dimension compared to adolescents aged from 17 to 19 years. In health responsibility, both groups of adolescents aged from 17 to 19 years and from 14 to 16 years reported significantly higher averages than adolescents aged from 10 to 13 years. Both groups of adolescents aged from 17 to 19 years and from 14 to 16 years reported significantly higher averages than adolescents aged from 10 to 13 years in life appreciation. Conclusion: Differences in health promoting activities based on adolescents’ gender is an area that needs more investigation. Because of the importance of social support, family and peer support must be improved. Implications for Nursing: The differences in performing health promoting activities based on adolescents’ gender are areas that need more attention. Fostering social support from family and peers is crucial to enhance adolescents’ health. It is mandatory to activate the role of the community health nurse as soon as possible. Parents and teachers must have adequate information about the developmental changes during adolescence. Keywords: Adolescents’ health, Health promotion, Peer support, Family support.

Published: September 2023

Background: Hygiene throughout the menstrual cycle is a significant public health concern, yet it is not recognized or appropriately addressed in many parts of Jordan. Purpose: The study aims to assess the level of knowledge and practices of menstrual hygiene among adolescent schoolgirls in the Jordanian Badia region. Methods: A descriptive cross-sectional study was conducted from February to March 2022. Data was collected from a convenience sample of 550 girls aged 12 to 18 years from six schools for girls in the Badia region using a questionnaire that assessed knowledge and practices of the menstrual cycle. Descriptive statistics (mean, standard deviation, frequency, percentage) and multivariable logistic regression analysis were used to determine the predictors of the https://jjnr.just.edu.jo/jjnr/ Menstrual Hygiene - 2 - level of knowledge and practices of the menstrual cycle. Results: The mean age of the participants was 15.5 years. About 65% of the adolescent schoolgirls have adequate level of knowledge. Regarding practices, around 58% of the adolescent schoolgirls have a poor level. The highest score was for” Schoolgirls should have a discussion with their mothers about menstruation and what to do during their periods”, while the lowest score was for “If she has to, she will have to change the pads at school”. In multivariable analysis; age >16 [OR = 2.10, 95% C.I (1.91–2.23)], mothers’ highest level of education [OR = 2.32, 95% C.I (2.25–2.39)], and family income [OR = 1.71, 95% C.I (1.58–1.83)] were the predictors of safe knowledge and practices of the menstrual cycle. Besides, age >16 [OR = 2.21, 95% C.I (2.11–2.33)], mothers’ highest level of education [OR = 2.89, 95% C.I (2.69–2.92)], and family income [OR = 2.01, 95% C.I (1.90–2.15)] were the predictors of practices of the menstrual cycle. Conclusion: Overall, the adolescent schoolgirls are reasonably knowledgeable of menstrual hygiene. On the other hand, the girls' overall level of practices was poor. So, menstrual hygiene knowledge and practices need to be improved by educating girls about menstruation and menstrual hygiene before menarche in order to protect them against Reproductive Tract Infections (RTIs). Implications for Nursing: There is a need to teach girls about the importance of personal hygiene to have confidence in themselves.

Some roofs in Indonesia still use concrete tiles because they are expensive and heavy. Indonesia is also the country that produces the most wood and coal in the world, this will cause sawdust and fly ash waste. Therefore, research was carried out aimed at using sawdust and fly-ash waste as mixed materials and trying to make lighter concrete roof tiles. So that in its use it can lighten roof construction and also utilize waste so that concrete roof tiles become more economical but have quality that meets SNI. The method used is an experimental method, with a cement and sand mixture composition of 1: 3 and using 4 variations of test objects, namely for sawdust variation A, 0%; B, 25%; C, 0%; D, 25% of the sand weight while for fly ash variation A, 0%; B, 0%; C, 25%; D, 25% of cement weight. This test includes appearance properties, size, flatness, bending load, water absorption and seepage. The average bending load results in variations A = 170,632 kg, B = 168,933 kg, C = 195,446 kg, D = 179,812 kg. For the average water absorption test results for variations A = 9.44%, B = 10.07%, C = 6.12%, D = 8.13%. The use of sawdust can reduce flexural strength and increase water absorption and the addition of fly ash will increase flexural strength and reduce water absorption compared to normal concrete roof tiles. Therefore, it can be concluded that concrete roof tiles with the addition of sawdust and fly ash are better, economical and lighter than concrete roof tiles without added materials and still meet SNI.

Almost all building construction projects use concrete as the material. The dead load of a construction building is affected by the specific gravity of the concrete. Lightweight concrete has a unit weight below 1900 kg/m3 (SNI 03-2847-2002). Lightweight concrete uses lightweight aggregate as a constituent, so PET plastic and paper can be used as aggregate substitutes. PET plastic has the characteristics of being durable, strong, light, thick, and with good abrasion resistance, which has a positive effect on the compressive strength test. The paper contains hydrogen, which can bind to OH molecules resulting in a stiff, stable, and strong bond. When the water evaporates, small voids filled with air will form, causing the concrete to become lighter. Based on this, an innovation emerged: the manufacture of lightweight concrete that utilizes PET and paper plastic waste. The study aimed to utilize PET and paper plastic waste as an aggregate substitute for lightweight concrete in practical building columns. This study will use experimental methods with variations in paper waste of 0% and 4% and variations in PET plastic waste of 0% and 0.2%. Cylindrical specimens measuring 15 cm x 30 cm were tested for compressive strength at seven days and 28 days of concrete and absorption at 28 days of concrete. The results of this study are that PET and paper plastic waste can be used as an aggregate substitute for lightweight concrete for practical columns and can achieve concrete compressive strength exceeding the K-125 plan by using SNI 7394:2008 as a reference for Job Mix Design.

The existence of infrastructure development has increased rapidly in encouraging global competitiveness, including infrastructure development in Indonesia. In infrastructure development, there are many aspects that must be considered. The planning stage is the most important stage in infrastructure development, because it will determine the quality of the building to be produced. Therefore, infrastructure development in Indonesia must use good construction material design to improve the quality of buildings and minimize the impact of damage to buildings. One of the alternative efforts made is to improve the quality of building quality by utilizing materials that can reduce expensive development costs and are more environmentally friendly. The use of palm kernel shell ash and polypropylene fiber  waste can be an alternative solution to this problem.  The research method carried out is quantitative experimental conducted in the laboratory with variations in test objects in the form of (0% ACS; 0% PP); (6 % ACS;0% PP); (0 % ACS;6% PP); (3% ACS;3% PP) tested for compressive strength and flexural strength at 28 days concrete life. Palm kernel shell ash waste was chosen as an added material for concrete mixture because it has the same properties as cement, namely silica (SiO4), while polypropylene fiber  was chosen because it can function as  a filler that binds hollow concrete. From the research that has been done, several variations of test objects that have been made have been made then have gone through a testing process and compared to normal concrete K-300, modified  concrete (3% ACS; 3% PP) is concrete with optimum variations that are more efficient and have high quality in compressive and flexural strength test results, which are 31,174  MPa and 30 MPa from normal concrete quality results.

Published: September 2023

This current research study examined if there is a linear relationship between various Emotional Intelligence traits and Transformational Leadership Traits among a sample of 104 licensed Certified Public Accountants (CPA) located in the United States who are currently not in workplace leadership positions. This research is appropriate for CPA professionals because CPA professionals must evaluate different points of view, conduct an effective analysis of accounting data, and embrace the highest ethical standards as part of their professional duties. Moreover, Transformational Leadership traits (Avolio & Bass 2004) fit nicely within Peter Salovey and John Mayer’s (1990) elements of Emotional Intelligence. Overall, the research study did find evidence for positive linear relationships between the predictor variables of Emotional Intelligence traits of Managing Their Own Self-Relevant Emotions and Managing Others’ Emotions among licensed Certified Public Accountants (CPA) and the dependent variables of Transformational Leadership Traits related to Idealized Attributes, Inspirational Motivation, Intellectual Stimulation, and Individualized Consideration. The researchers recommend that any future professional development among Certified Public Accountants (CPA) who aspire to seek out workplace leadership positions needs to be focused on the cornerstones of Managing Their Own Self-Relevant Emotions and Managing Others’ Emotions.
Relationship Between Triarchic Psychopathy Personality Traits and Academic Motivation: A Study of Accounting Students in China
Authors: Hing Ho Miu
Published: September 2023

With the growth of China’s economy, the accountancy profession in China played a vital role in serving the industry and in regulating the capital market. To be successful in becoming a professional accountant, accounting majors must have both the required skills and professional knowledge and the appropriate personality for that profession. Therefore, it is crucial to find out whether the personality of students studying accounting degrees in China will affect their academic motivations in studying accounting. The purpose of this paper is to investigate the relationship between triarchic psychopathy personality traits and the academic motivation of students studying accounting in China. A self-administered questionnaire survey was conducted to collect data from students who were studying accounting in universities across China. A total of 125 responses were collected for descriptive statistics, and correlation and regression analysis using SPSS 25. The findings of the study suggested that undergraduate students studying accounting degrees were mainly motivated by their concerns about their future career prospects, contribution to the community, and self-exploration. Concerning their personality trait, the highest mean value among the three traits was boldness, which means, to a certain extent, they could remain emotionally stable even if they are working under pressure. Nevertheless, the results of the correlation and regression analysis suggest the relationship between triarchic psychopathy personality traits and academic motivation of students studying accounting in China is not significant. The results, however, could not be generalized to all accounting students in China since the valid samples collected were only 125 and non-probability sampling technique was adopted in this study. The accounting professional bodies may benefit from the findings of this study in their member recruitment strategies, as well as the accounting education providers in assessing the candidates who are suitable for study accounting and in curriculum development of accounting courses.
Theological and Biblical Foundations for Performance Ethics in Congregational Worship
Authors: Odiase Rev. Yeside
Published: September 2023

Changes in global trends are throwing up discordant views in Christian worship which requires a biblical-theological approach to maintain a balance. This paper advocates for the necessity of standard ethics that is guided by theological and biblical principles for congregational worship. These guiding principles entrenched in the Old and New Testaments are fundamental to meaningful worship. The article examines the meaning of performance ethics, the concept of congregational worship, biblical and theological concepts of performance ethics in worship and the concept of congregational music in worship.  The paper concludes with the recommendation that congregational worship which includes church music should be guided by biblical principles underpinning actions, liturgy and disposition with robust performance ethics to enrich worship and glorify God.

Sociological application of behavioural theories to work performance of academic staff in Nigerian universities

Published: September 2023

Several authors have researched workplace circumstances and employee performance in organisations. Personal observations, documented observations, and discoveries in the literature all provided an incentive for this investigation. Some systematic observations revealed that academic staff in Nigerian universities are subjected to some unfavourable workplace conditions, even though they are expected to perform well in teaching, publish quality research papers that can contribute to global knowledge and development, and engage in community development services. Major theories have attempted to explain employee productivity in the workplace. Using secondary data, this article explores the Two Factor model by Fredrick Herzberg, the Contingency theory of leadership and the Expectancy theory by Victor Vroom. They were most relevant in associating motivating factors with the work performance of employees in the organisation. The criticisms of each theory have paved the way for theoretical triangulation and, thus, a synthesis of all three theories to explain the work performance of academic staff members in Nigerian universities. The article resolved that incentives are indeed essential in order to increase the performance of academic staff in Nigerian universities.
Identification of Surgical Instruments Using a Low Frequency Magnetic Field
Authors: Ibrahim Ibrahim , Draeger Tobias , Wittenberg Thomas
Published: September 2023

Background: As part of a open surgical intervention, it is desirable to identify, track and count the surgical instruments used, in order to document and potentially optimize the process. In the past, various technologies have been proposed to this end, as e.g. RFIDs attached to or included in the instruments, contact-less identification by image analysis or (bar-, QR-) codes, or counting by human resources, but all of them having their individual drawbacks. Objective: We present and evaluate a new method to identify metallic-conductive surgical instruments using Low Frequency (LF) magnetic fields. Method: The investigated LF magnetic field approach is based on the IndLoc system developed by the Fraunhofer IIS - originally for metallic asset identification within the field of supply chain management - and is applied on small collection of 13 typical surgical tools (four scissors, two needle holders, four tweezers, two retractors, a bone curette) for open surgery. Results: 9 out of the 13 instruments can be correctly identified, two pairs (2 short and 2 medium tweezers) are too self-similar and could not discriminated correctly from each other. Conclusion: These initial experiments show that an LF-based identification of metallic surgical tools is feasible, but the system needs to be modified (with more and smaller coils) to increase the geometrical resolution to better distinguish between self-similar and potentially more objects.
Therapy monitoring of psoriatic arthritis patients with and without skin involvement via objective evaluation of near infrared fluorescence optical imaging: A pilot study
Authors: Zerweck Lukas , Wesarg Stefan , Köhm Michaela , Kohlhammer Jörn
Published: September 2023

In this work, we investigate the possibility of automatically and objectively evaluate an initialized therapy for psoriatic arthritis patients (therapy monitoring). Near infrared fluorescence optical imaging (NIR-FOI) is used to visualise the microcirculation in the hands, giving insights into possible inflammations (e.g. synovitis). Due to the time consuming and expansive data acquisition, we firstly investigate the feasibility of NIR-FOI in this scope of application using retrospective data. To increase the data quality and harmonize the heterogeneous patient population, certain inclusion criteria must be met, leaving only a limited amount of data sets for data analysis. A neural network was trained to segment the hands into areas of interest (e.g. joints and fingers) and an image registration pipeline was developed to compare identified regions of interest among different patient visits. It is shown that data from different visits are not directly comparable and thus, needs to be normalised. Due to the limited amount of meta data, only a simple normalisation can be performed. Even though with this normalisation the therapy monitoring cannot be carried out, the normalised data shows an increased agreement to a medical label in comparison to unnormalised data. Therefore, we conclude that further research can lead to a robust therapy monitoring algorithm.
Actively shielded capacitive proximity sensor for endoscopy

Published: September 2023

Flexible endoscopes are widely used for diagnostic and therapeutic procedures on internal organs and tissue surfaces. Accurate positioning of the endoscope tip is critical for obtaining clear images and avoiding tissue damage. Proximity sensors can provide information about the distance to the surrounding tissue, which can help align the endoscope tip and navigate along curved paths. This paper presents a method of proximity measurement using capacitive sensors with active shielding to determine the radial distance between an endoscope and surrounding tissue. The capacitive sensor consists of four copper foil electrodes attached to a 9.5 mm diameter ring. Two different active shielding designs were investigated and compared to reduce the sensing angle and minimize lateral effects. Capacitance was measured as a function of distance using a linear stage. A MATLAB script controlled the linear stage and calculated the distance from the measured capacitance. The results showed that advanced active shielding could be useful to reduce the sensing angle (angular space where capacitance sensor detects capacitance changes.). This method provides a cost-effective solution for radial distance measurement in endoscopy, essential for improving diagnostic and therapeutic procedures.
