Authors: Bhattarai Ganesh , Pokhrel Dhruba Raj , Dahal Rewan Kumar , Sharma Sumedha
Published: May 2021

Researchers concentrated on antecedents and consequences of abusive supervision and paid less attention to factors that mitigate abusive supervision’s harmful effect in an organization. As a response to the situation, this study was carried out to measure the (i) direct impact of abusive supervision on withdrawal behavior, (ii) direct impact of ability-job-fit on withdrawal behavior, and (iii) defensive role of ability-job-fit for the harmful effect of abusive supervision on withdrawal behavior. Perceptual data were collected from the 350 employees working in the Nepalese multipurpose saving and credit cooperative limited. To infer the conclusion, data were analyzed quantitatively adopting the deducting reasoning approach and positivist research philosophy. This study found that there was- a positive impact of abusive supervision on withdrawal behaviors, negative impact of ability-job-fit on withdrawal behaviors, ability-job-fit defended the harmful effect of abusive supervision on withdrawal behavior. Moreover, abusive supervision’s harmful effect on withdrawal behaviors was less for those who perceived high ability-job-fit and vice versa. Numbers of practical and theoretical implications are suggested.

The aim of this review was to synthesize the aggregated studies aimed at improving health care knowledge, detection practices and management of dementia among healthcare professionals (HPs). Healthcare professionals play a key role in the detection and management of dementia. However, there is a gap in the literature as to what represents best practice with regard to educating HPs in this area. We searched citation index Google scholar, Scopus and Pub Med, Medline, were searched for relevant articles from 2000-2019 without data limit. Inclusion criteria were (1) intervention studies aimed at improving HPs practices concerning dementia care (2) the educational intervention focused on knowledge, detection practice and management of dementia, and (3) peer-reviewed and written in English. Of 4968 articles identified, only 13 articles (six GPs, two clinical/organization care based, one nurse, one physician and affiliated staff and one with physician, manager and therapists based studies) were suitable for inclusion and these all were from developed countries. Seven studies were randomized controlled trials (RCTs), 1 prospective, 2 GPs and supervisors intervention, 1 cohort study, and 2 clinical /organizational care services clustered randomized study. Overall, the methodological quality of these studies was poor, particularly with regard to the methods utilized and sample sizes however, combined programs of, practice based workshops with community and multi-faced educational program were the most effective. The continuous educational intervention program can improve the health professionals’ diagnosis and management knowledge, confidents and negative perception of dementia.

Authors: A. Jabber Abdullah , H. Thaher Raad
Published: May 2021

This article presents design and simulation of a new compact four-element dual-band MIMO frequency reconfigurable antenna that can be reconfigured for WiMAX and LTE applications. The antenna includes four elements at the same FR4 substrate with an optimized overall size of 65x65x1.6 mm3 and an optimized partial GND plane of 30x11.125 mm2. The reconfiguration rate is between 2.41 and 3.99 GHz that can cover the WiMAX and LTE wireless devices by applying just one RF (PIN) switch to change the operating frequency. The antenna operates on the two states of the PIN diode under its two states ON and OFF with (2.7 GHz, and 2.8 GHz) resonant frequencies respectively. The proposed antenna produces acceptable simulation results for the MIMO system by achieving gain from (3-7.2) dBi, less than -14.5 dB coupling effect, less than 0.28 envelope correlation coefficient, and diversity gain range from 8.4-10.
EFFECT POLYPROPYLENE OF FIBER ON DRYING SHRINKAGE CRACKING OF CONCRETE PAVEMENT USING RESPONSE SURFACE METHODOLOGY
Authors: A. Abdulridha Mundher , M. Salman Mohamed , S. Banyhussan Qais
Published: May 2021

In concrete when tensile stress surpasses the strength of the traction contributes to cracking, which is called shrinkage cracking. Shrinking allows for curling and folding of concrete. The principal goal of this research work is to develop optimal Eco-friendly concrete mixtures by using Response Surface Methodology (RSM), including different quantities of polypropylene fiber used in concrete pavement, identify the shrinkage factor (shrinkage cracking) in the concrete pavement. The testing program included using of thirty mixtures to investigate four parameters namely cement content (300,400 and 500) kg / m3, steel fiber (0, 0.075, and 0.15 vol. %), three separate amounts of polypropylene fiber (0, 0.35, and 0.7 vol. %), and (0, 5, and 10 %) silica fume by cement weight. The results indicated that the amount of cement is the higher factors affecting the shrinkage cracking of concrete. For the purpose of obtaining the best mixture for optimal components to design concrete mixtures used in the concrete pavement that give the compressive strength [> 30 MPa], flexural strength [> 4.1 MPa], minimum CO2 emissions, less cost, and fewer cracks width according to requirements and Iraqi specifications are cement [385.94] kg/m3, silica fume [0.000198Vol.%], steel fiber [0.0564 Vol.%], PP fibers [0.2926 Vol.%], Carbon dioxide emissions [379.59] kg CO2 -e / m3, total cost 99.96 USD / m3, and crack width [0.1]mm.

Authors: S. Mahdi Muhanad , K. Mohaisen Saad
Published: May 2021

The purpose of this paper was concerned of the behavior of six samples of deep beams under the influence of pure torsion. Such samples were self-compacting concrete (SCC) and two ratios of Steel Fibers (SF (were also added (0.75 % and 1.5 %). This study examined the behavior of the samples when pure torsion was applied and reacted to angles of torsion, longitudinal strains and concrete strains. It was obvious from the results of the test that the addition of steel fiber to the SCC mixture increased the strength of the compression and tensile strength, which increased the hardness of the samples, thereby decreasing the response of the samples to the angle of twisting, longitudinal strains of concrete and concrete strains.

Published: May 2021

Tigris River is the only potable source in Baghdad city therefor many water treatment plants were built on the banks such as Al-Karkh, Sharq Dijla, Al-Sadr, Al-Wathba, Al-Karama, AlQadisia, Al-Dora, Al-Wahda, and Al-Rashed project. Tigris River suffers from the pollution that comes from various sources such as Industry, domestic sanitation, and farming activities therefore several indices were used to calculate water quality within Baghdad to convert physicochemical parameters of water to a single value that represents the river status (good, bad, very bad, etc..). The aim of this review paper to show the results of previous studies about the water quality for the Baghdad region. Most results showed that water quality was good in the north of the city of Baghdad and bad in the south of Baghdad. The deterioration of water quality was due to many reasons such as the discharge of wastewater directly into the river without pretreatment, increase in (Eclectic conductivity, Turbidity, and total suspended solids, total hardness, Iron ion, the fecal coliform) concentrations, and Climate change, therefore, Tigris River needs intensive treatment before using by humans.
Hindutva Past and Present
Authors: Sahgal Gita
Published: May 2021

This essay outlines the beginnings of Hindutva, a political movement aimed at establishing rule by the Hindu majority. It describes the origin myths of Aryan supremacy that Hindutva has developed, alongside the campaign to build a temple on the supposed birthplace of Ram, as well as the re-writing of history. These characteristics suggest that it is a far-right fundamentalist movement, in accordance with the definition of fundamentalism proposed by Feminist Dissent. Finally, it outlines Hindutva’s ‘re-imagining’ of secularism and its violent campaigns against those it labels as ‘outsiders’ to its constructed imaginary of India.

Neoliberalism, Hindutva and Gender
Authors: Chhachhi Amrita
Published: May 2021

This article explores the convergence and contradictions between the two hegemonic projects of neoliberalism and Hindutva and the reinforcement/reconstruction of patriarchal gender relations in relation to welfare. Analysis of some key social policies and specific legal interventions show the fusion of the two in the construction of the family/nation/gender related to population regulation, governance of populations, the forging of a paternal contract, the move from welfare to financialization and the undermining of labour rights through regulatory and disciplinary labour codes. The convergence of neoliberalism and Hindutva results in a shift from rights-based entitlements to further commodification and digital financialization and the creation of a hindutvatised neoliberal subjectivity.

Authors: Yuval-Davis Nira
Published: May 2021

This article provides a framework to understand the ways in which the Israeli state, Jewishness, neo-liberalisation and religionization of the Zionist project have been interwoven historically. This interweaving, however, has deepened since the beginning of Israeli religionization after the 1967 war and especially with Israel’s embrace of neoliberalisation during the 1980s. It examines the effects these have had on gender relations in Israel, focusing on the incorporation of ultra-orthodox Israeli Jewish women into the labour market and higher education as an illustrative case study.

Key words: Israel, Zionism, Jewishness, religionization, Jewish fundamentalism, neo-liberalisation, ultra-orthodox women.

A pandemia relacionada a COVID-19, trouxe mudanças nos campos social, econômico e educacional. Seguindo as medidas de restrição da Organização Mundial de Saúde (OMS), Instituições de Ensino brasileiras suspenderam as atividades presenciais, aderindo inclusive a formas de ensino não presencial. Dessa forma, esse trabalho teve como objetivo conhecer as percepções de discentes de uma Instituição Federal de Ensino Superior cursando disciplinas em Período Letivo Excepcional (PLE). Para alcance dos objetivos, convidou-se licenciandos em biologia cursando disciplinas de forma remota na referida instituição. A participação foi firmada por meio do aceite dos participantes a um Termo de Aceite Livre e Esclarecido (TCLE) e a coleta de dados ocorreu por meio de um questionário semiestruturado, confeccionado a partir da ferramenta Google Forms. Com base nas respostas obtidas no questionário, foi possível notar diversas complicações enfrentadas pelos estudantes durante o PLE, dentre elas problemas relacionados ao acesso aos conteúdos e familiarização com as plataformas utilizadas, a sobrecarga de atividades e problemas de caráter pessoal, transitando até mesmo pela dificuldade em se adaptar às novas circunstâncias. Além disso, as questões discursivas presentes no questionário servem como base para traçar novos caminhos em momentos futuros, visto que proporcionam reflexões e contribuem para o aprimoramento da modalidade de ensino remoto, visando superar as atribulações apontadas pelos estudantes. Isto posto, concluiu-se que as reflexões geradas pelo contexto pandêmico serão extremamente pertinentes para a reformulação da educação brasileira num momento pós-pandemia, uma vez que a substituição do modelo presencial pelo ensino remoto expôs em larga escala as fragilidades que permeiam o processo de ensino e aprendizagem vigente no Brasil.

In the normative base of Ukraine for the safe mining of coal seams, only five indicators of the degree of metamorphism are used to predict the manifestation of their hazardous properties during mining operations: mass release of volatile substances during thermal decomposition of coal without air (Vdaf) access to characterize coal; volumetric yield of volatile substances daf V V to establish the distinctive properties of anthracites; logarithm of electrical resistivity (lg); the thickness of the plastic layer (y) and the grade of coal (M) for predicting the outburst hazard of seams. When developing regulatory documents, it was assumed that these criteria for assessing the degree of coal metamorphism remain constant within one mine field. Their values, as mining operations show, are influenced by the location of the coal sampling site in relation to the distance from relatively large geological disturbances or the boundaries of the gas weathering zone. In most cases, the boundaries of mine fields are usually relatively large geological faults. The proximity of the locations of coal sampling points to them influences the obtained results of evaluating the properties of mine layers. Аdjusting indicators (Vdaf, daf V V , lg, y ,M) for individual mines on the possible impact of geological disturbances, the depth of the mining robot and the distance from the zone of gas weathering, according to the requirements of regulatory documents. For this reason, it is of scientific and practical interest to establish the possible ranges of change in the indicators of the degree of metamorphism of coal within the same mine layer. The results of research in this direction are relevant, as they are necessary to improve the regulatory framework for the safe mining of coal mines. A possible change within a separate mine field was considered using the example of the indicator Vdaf as the most studied at present. According to a specially developed methodology, the analysis involved data on 2193 mines from different coal basins. Most of them belong to the mines of the Donetsk basin (1773). The rest of the basins account for information on 460 mine layers, including data on 46 mine layers for the Lvov-Volyn basin.

In this work, seismic-explosive waves are investigated on the basis of mathematical simulation of short-delayed explosion of a system of charges and effective and seismic-safe schemes are calculated. Numerical simulation of the explosion of a group of charges of cylindrical symmetry in a rock mass is carried out. During the development of the explosion, two stages are distinguished. At the first stage, the explosion of a cylindrical explosive charge in an unlimited soil mass is considered. The principle of superposition of fields is used in the study of explosions of two or more charges, while the influence of the intervals of deceleration and distribution of masses of charges within a group on the parameters of seismic-explosion waves is investigated. It is established that approximately the same stress state is achieved in the soil mass in the near and middle zones of the explosion, which is necessary for the destruction of the rock. The efficiency of application of the proposed schemes for mining in quarries is proved. At the second stage of solving the problem, an assessment of the total action of a short-delayed explosion of a system of cylindrical charges is made. The results of theoretical studies on the determination of the optimal short-delay detonation schemes depending on the distribution of masses within the group and the deceleration intervals are presented. The development of the method for calculating seismic vibrations based on mathematical modeling of a short-delayed explosion of a system of charges, which makes it possible to calculate wave parameters depending on the distribution of masses of charges within a group of deceleration intervals, is made and proved its effectiveness.

The agglomeration process is one of the complex, multidimensional technological processes; it takes place under conditions of a large number of disturbing influences. As a result, the amount of return during sintering reaches 40-50%. The work is devoted to the development of a mathematical model capable of predicting and controlling the sintering point based on real-time data. As the main parameters for the construction of predictive models, data measured in real time were used – the temperature in the vacuum chambers and the gas velocity determined through the measured pressure (rarefaction) in the vacuum chambers. This paper describes the methodology and basic algorithms for modeling agglomeration processes, starting from the ingress of the charge into the sinter machine and ending with the production of a suitable agglomerate. The obtained curves of the developed mathematical model of temperature in vacuum chambers served as the basis for testing the forecast model based on the use of the theory of gray systems and the optimization algorithm of the "swarm of particles". Based on the developed mathematical model, a system for predicting the sintering point is constructed, which is the basis for determining the quality of the agglomerate, which will reduce the return volume during sintering. The general structure of the sinter control system based on a dynamic predictive model is also proposed. The practical significance of the developed predictive model based on the theory of gray systems is as follows: - forecast of the sintering point value of the agglomerate and synthesis of the control action based on the forecast; - the algorithm for constructing a mathematical model of the forecast can be used for any process that has the character of a "gray exponential law".

Mining of the off-balanced and balanced reserves of mines, being under closure or completing their operation, required the implementation of mobile, complex, and environmentally friendly development technologies based on the processes of well underground coal gasification (WUCG) that unites mining of coal and its energy-chemical use. Environmental friendliness of the WUCG process is possible due to its controllability, hermeticity of the underground gas generator, and complex use of cogeneration technologies in the closed cycle of purification and processing of gasification products. The set engineering tasks were performed using analytical studies, bench studies and field studies. Efficiency of thermal energy generation were studies using rocks enclosing the underground gasifier and generator gases. These sources being the basic heat generating segments of energy chemical complex for coal gasification being formed at the territories of operating coal mines or mines at the stage of their closure. Prospects of coal gasification and thermal energy generation using rock disposals of coal mines have been estimated.

South Africa, in general, is plagued by high unemployment, especially among the youth. The study explored the relationship between mentorship and successful youth entrepreneurship at Telkom, South Africa. The primary focus of the investigation was to establish whether mentorship could be the answer to unemployment and the declining youth entrepreneurship in the City of Tshwane. A qualitative research approach was applied in this study, using the Telkom mentorship programme as the sample. The sample consisted of mentors and youth mentees, obtained from the Telkom mentorship database. Data was collected using semi-structured, open-ended interviews. Data analysis was done using thematic analysis with Atlas Ti 8.0. The literature shows that mentoring has benefits for both mentors and entrepreneur mentees. It also shows that the government and private sector can play a key role in youth entrepreneur mentorship. The findings of the study have proven that mentorship yields positive results for youth entrepreneurs, which supports the literature in this study. The findings of the study yielded three themes, which were as follows: success factors for mentorship, inhibiting factors for mentorship, and influence of mentorship on successful youth entrepreneurship. In addressing the objectives of this study, the findings have proven that there is a relationship between mentorship and successful youth entrepreneurship. The recommendations made in this study include improvements in the mentorship programme for mentees and mentors, initiatives by government that include more mentorship programmes and better communication as well as providing funding for mentorship programmes. Further research, to establish the correlation between mentorship and successful entrepreneurship, is recommended.

This present paper aims to investigate strength characteristics of cement mortar using natural sea sand as fine aggregate in different curing conditions. Research was carried out with making mortar mixtures by two types of cement, Portland Composite Cement (PCC) and Pozzolana Portland Cement (PPC) with tap water as mixing water. Characteristics of fine aggregate and strength of cement mortar use river sand (RS), sea sand (SS), and washed sea sand (WS) were observed. Further, specimens of cube mortar in size of 50 mm x 50 mm x 50 mm of six mortar mixture series were casted according to Indonesian Standard. At 24 hours after cube specimens were casted, cube mortar specimens were cured in three curing conditions such as tap water curing (TC), seawater curing (SC) and air curing (AC). After curing at certain period (3-day, 7-day, 14-day, and 28-day), cube mortar samples were tested in compressive strength. Results concluded that sea sand aggregate improve characteristic of mortar in compressive strength up to 28 days in all curing conditions, and there was no significant effect of type of curing water (TC and SC) on 28-day strength performance of mortar was obtained. In addition, sea sand could potentially be utilized as an aggregate in production of mortar and/or concrete.

Authors: Reichold Michael , Selau Marina , Graessel Elmar , Kolominsky-Rabas Peter L. , Prokosch Hans-Ulrich
Published: May 2021

The benefits of eHealth interventions for people with dementia and their informal caregivers have been demonstrated in several studies. In times of contact restrictions, digital solutions have become increasingly important, especially for people with dementia and their mostly elderly caregiving relatives, which are at increased risk of severe illness from COVID-19. As in many other health areas, there is a lack of digital interventions in the dementia landscape that are successfully implemented (i.e., put into practice), especially digital interventions that are scientifically evaluated. Evaluated and proven effective digital interventions exist, but these often do not find their way from research into practice and stay on low-level implementation readiness. Within the project digiDEM Bayern, a digital platform with digital services and interventions for people affected by dementia (people with dementia, caregivers, volunteers and interested citizens) is established. As one digital intervention for informal caregivers, the ‘Angehörigenampel’ (caregivers’ traffic-light) was developed, which is able to assess the physical and psychological burden of caregivers. This can help to counteract the health effects of caregiving burden early on before it is too late. The development of the digital intervention as a WordPress-plugin was kept generic so that it can easily be adapted to other languages on further websites. The ‘intervention as a plugin’ approach demonstrates an easy and flexible way of deploying eHealth interventions to other service providers, especially from other countries. The implementation barriers for other service providers are low enough for them to be able to easily integrate the eHealth intervention on their website, enabling more caregivers to benefit from the disseminated eHealth intervention.

Published: May 2021

Background: Physicians spend a lot of time in routine tasks, i.e. repetitive and time consuming tasks that are essential for the diagnostic and treatment process. One of these tasks is to collect information on the patient’s medical history. Objectives: We aim at developing a prototype for an intelligent interviewer that collects the medical history of a patient before the patient-doctor encounter. From this and our previous experiences in developing similar systems, we derive recommendations for developing intelligent interviewers for concrete medical domains and tasks. Methods: The intelligent interviewer was implemented as chatbot using IBM Watson assistant in close cooperation with a family doctor. Results: AnCha is a rule-based chatbot realized as decision tree with 75 nodes. It asks a maximum of 44 questions on the medical history, current complaints and collects additional information on the patient, social details, and prevention. Conclusion: When developing an intelligent digital interviewer it is essential to define its concrete purpose, specify information to be collected, design the user interface, consider data security and conduct a practice-oriented evaluation.

Objectives: In this study, we investigated discourses on HIPAA in relation to COVID-19. Methods: Through a search of media sources in the Factiva database, relevant texts were identified. We applied a text mining approach to identify concepts and themes in these texts. Results: Our analysis revealed six central themes, namely, Health, HIPAA, Privacy, Security, Patients, and Need, as well as their associated concepts. Among these, Health was the most frequently discussed theme. It comprised concepts such as public, care, emergency, providers, telehealth, entity, use, discretion, OCR, Health and Human Services (HHS), enforcement, business, and services. Conclusion: Our discourse analysis of media outlets highlights the role of health data privacy law in the response to global public health emergencies and demonstrates how discourse analysis and computational methods can inform health data protection policymaking in the digital health era.

Background: Physical activity helps improve the overall quality of life. The correct execution of physical activity is crucial both in sports as well as disease prevention and rehabilitation. Little to no automated commodity solutions for automated analysis and feedback exist. Objectives: Validation of the Apple ARKit framework as a solution for automatic body tracking in daily physical exercises using the smartphones’ built-in camera. Methods: We deliver insights into ARKit’s body tracking accuracy through a lab experiment against the VICON system as Gold Standard. We provide further insights through case studies using apps built on ARKit. Results: ARKit exposes significant limitations in tracking the full range of motion in joints but accurately tracks the movement itself. Case studies show that applying it to measure the quantity of execution of exercises is possible. Conclusion: ARKit is a light-weight commodity solution for quantitative assessment of physical activity. Its limitations and possibilities in qualitative assessment need to be investigated further.

Background: There is a lack of secure official communication channels for peer review and peer feedback on medical findings. Objectives: We aimed to utilize the existing Austrian eHealth infrastructure to enable review and feedback processes. Methods: We extended the IHE XDW workflow document to enable the exchange of text messages (i.e., comments on documents or images) over an XDS infrastructure. Results: The workflow enables the exchange of comments on specific sections of CDA documents or radiological images and was verified in an XDS test environment. Conclusion: The presented solution is a proof of concept and the potential basis for the specification of a new IHE workflow definition.
Introducing a Navigation Algorithm for Reducing the Spread of Diseases in Public Transport Networks

Reducing passenger flow through highly frequented bottlenecks in public transportation networks is a well-known urban planning problem. This issue has become even more relevant since the outbreak of the SARS-CoV-2 pandemic and the necessity for minimum distances between passengers. We propose an approach that allows to dynamically navigate passengers around dangerously crowded stations to better distribute the passenger load across an entire urban public transport network. This is achieved through the introduction of new constraints into routing requests, that enable the avoidance of specific nodes in a network. These requests consider walks, bikes, metros, subways, trams and buses as possible modes of transportation. An implementation of the approach is provided in cooperation with the Munich Travel Corporation (MVG) for the city of Munich, to simulate the effects on a real city’s urban traffic flow. Among other factors, the impact on the travel time was simulated given that the two major exchange points in the network were to be avoided. With an increase from 26.5 to 26.8 minutes on the average travel time, the simulation suggests that the time penalty might be worth the safety benefits.

Published: May 2021

Background: Intensified research and innovation and rapid uptake of new tools, interventions, and strategies are crucial to fight Tuberculosis, the world’s deadliest infectious disease. The sharing of health data remains a significant challenge. Data consumers must be able to verify the consistency and integrity of data. Solutions based on distributed ledger technologies may be adequate, where each member in a network holds a unique credential and stores an identical copy of the ledger and contributes to the collective process of validating and certifying digital transactions. Objectives: This work proposes a mechanism and presents a use case in Digital Health to allow the verification of integrity and immutability of TB electronic health records. Methods: IOTA was selected as a supporting tool due to its data immutability, traceability and tamper-proof characteristics. Results: A mechanism to verify the integrity of data through hash functions and the IOTA network is proposed. Then, a set of TB related information systems was integrated with the network. Conclusion: IOTA technology offers performance and flexibility to enable a reliable environment for electronic health records.

Background: Delirium is a patient safety issue that often occurs within the population of elderly people. As delirium may be characterized by fluctuating progress, the aim of this work is to find methods to visualize the occurrence of delirium over time in different patient stays in gerontopsychatric settings. Methods: We analyzed current data mining visualization techniques for clinical research using a delirium data set collected in a gerontopsychatric setting. Results: We identified heatmaps and dendrograms resulting from hierarchical clustering as a suitable visualization method. Conclusion: Heat maps with hierarchical clustering are a suitable data mining tool or visualization technique to study delirium cases in the time course of patient stays.
Co-Designing a Primary Care Breathlessness Decision Support System: General Practitioners Requirements Analysis, Workflow Assessment and Prototype Development
Authors: Sunjaya Anthony Paulo , Martin Allison , Jenkins Christine
Published: May 2021

Clinical decision support systems (CDSS) have been shown in a variety of diseases to lead to improvements in care. The aim of this study is to design a CDSS to assist GPs to assess and manage breathlessness, a highly prevalent symptom in practice. A focus group is conducted to explore the needs of general practitioners (GPs), assess current workflow to identify points for intervention and develop early prototypes for testing. Five GPs took part in the focus group elucidating 248 relevant data points which were then qualitatively analyzed using the Technology Acceptance Model as the theoretical framework. In general, there was a positive attitude towards the use of CDSS for breathlessness with various proposed features from the participants. Twelve high level workflow steps were identified with 5 as key points for intervention. Several proposed features such as reporting likelihood of causes of breathlessness in a patient, link with evidence-based recommendations, integration with clinical notes and patient education materials were translated into a prototype. Mixed-method studies are planned to assess its usability to inform subsequent iterations of the CDSS development.

Telehealth services for long-term monitoring of chronically ill patients are becoming more and more common, leading to huge amounts of data collected by patients and healthcare professionals each day. While most of these data are structured, some information, especially concerning the communication between the stakeholders, is typically stored as unstructured free-texts. This paper outlines the differences in analyzing free-texts from the heart failure telehealth network HerzMobil as compared to the diabetes telehealth network DiabMemory. A total of 3,739 free-text notes from HerzMobil and 228,109 notes from DiabMemory, both written in German, were analyzed. A pre-existing, regular expression based algorithm developed for heart failure free-texts was adapted to cover also the diabetes scenario. The resulting algorithm was validated with a subset of 200 notes that were annotated by three scientists, achieving an accuracy of 92.62%. When applying the algorithm to heart failure and diabetes texts, we found various similarities but also several differences concerning the content. As a consequence, specific requirements for the algorithm were identified.
