Development and real-world application of a taxonomy for business models in local energy markets

Local energy markets are often discussed as a means to solve the challenges of decentralization, decarbonization and digitization emerging from the energy transition. However, their (potential) business models, and thus their rationalization in our economy, remain largely unknown. Suitable business models are required to leverage economic benefits from local energy markets. We follow a multi-method approach to develop a taxonomy of local energy market business models. Firstly, we conduct 15 semi-structured expert interviews to gain first-hand knowledge of current and future business models. Secondly, a taxonomy development method is applied on the interviews in an iterative process. Our results show that the most profitable and long-term sustainable local energy market business models should focus on financial benefits as their main value proposition, should be consumer- and producer-centric, and should develop a trading platform offered by a service provider. A focus on energy and flexibility trading, and a highly interoperable information system aid the business success. Lastly, we compile an overview of current business models in nine real-world local energy market projects and apply the taxonomy to their business models. This case study shows that the implemented business models are very similar and only represent a small part of the discussed business models of local energy markets in the taxonomy. This shows that the implemented local energy market business models are currently in their very early development stages. They need to mature in line with the further development of local energy markets.

Consultations of hospital physicians in community health centers: Actors' identified impacts and difficulties

In 2016 different types of cooperation were identified between "Assistance publique - Hôpitaux de Paris" and community-based healthcare professionals, including consultations from hospital practitioners in community health centers. This work aims to study the advantages and difficulties of this type of cooperation. Interviews were conducted with hospital physicians, heads of hospital units and of community health centers. Data were collected by physicians for seven consultations. Regarding patients, these consultations gave access to specialists' expertise in deficit areas at no extra cost; the community health center is a more human-size structure and appointments were sometimes more quickly attributed. For physicians, consulting in the community health center afforded a more diversified activity and permitted to discover community practice. For the hospital unit, it could bring new patients and lead some patients living closer to the community health center to delocalize the follow-up consultations. This type of cooperation strengthened the relation between hospital and community-based practitioners but the relations remained informal. Amongst mentionable difficulties: the lack of information systems interoperability, the struggle in raising the interest of some physicians and an increased workload. If this type of consultation can be a first step in organizing hospital-community relations, it does not enable by itself a territorial coverage. Partnerships should include several community health centers but also physicians in independent practice. Larger partnerships can integrate the formalization of care pathways refocusing each actor on its field of expertise.

Moving Towards a Blockchain-Based Healthcare Information System.

One of the major problems that a national health system face is the lack of a unified clinical data management. In Greece, the critical and sensitive medical data generated during a patient lifetime are fragmented in one or more hospitals and healthcare services are not characterized by a 'continuity' factor. There is not the appropriate technological and administrative infrastructure for a unified patient medical history, prescriptions, laboratory tests or therapeutic plan. Technological, administrative and economic factors have led to this situation. We propose the integration and implementation of a blockchain network as a complementary technology to the existing information systems, so reliable and effective information management could be provided by a healthcare organization or the national healthcare system. Blockchain technology could be implemented as a bridge that can provide information systems interoperability within a hospital or between different hospitals.

MODELADO DE INFORMACION PARA FABRICACION ADITIVA

Nowadays any company that manages some technology needs to manage the information that has to take to make the decisions that mark its future. Processes, organizational models, and any processes that involve certain information and which are going to lead to some or other decisions must be properly managed. The same organization of the company is subject to a series of information and / or qualities that it is convenient to organize. In the same way that "organizations" need to be organized, the information that is handled to manufacture a physical product (object) must also be properly organized. In this are the information systems, intelligent systems, concurrent engineering, knowledge engineering, etc. So that the information of a company can be used by other collaborating companies have been created some standards that allow the communication. ISO 10303, better known as STEP, is the international standard that is fulfilling this goal of normalizing methods that allow what is called "interoperability". This is a very broad rule with many sections and applications. One of the parts of the standard is the Action Protocols, each designed with a general objective of meeting the needs of one or several sectors. Among these protocols of action there is one that fits perfectly in the objective of this thesis, is the AP242. The purpose of this research is to develop a proposal that incorporates the standard AP242 (ISO 10303) into the information model for a manufacturing technique that is growing at high speed, known as "Additive Manufacturing", using the feasible project methodology. Throughout the investigation, but especially in the final section shows how the AP 242 fits almost perfectly in the needs of Additive Manufacturing. As conclusions, the importance of the adoption of adequate international standards for new manufacturing technologies for the design and implementation of interoperable and scalable information systems to guarantee the productivity and growth of the industry is highlighted. Keywords: modelling, information systems, ISO 10303, performance protocols, Additive Manufacturing.

Large-Scale Ontology Alignment- An Extraction Based Method to Support Information System Interoperability

Ontology alignment is an important way of establishing interoperability between Semantic Web applications that use different but related ontologies. Ontology alignment is the process of identifying semantically equivalent entities from multiple ontologies. This is not always obvious because technical constraints such as data volume and execution time are determining factors in the choice of an alignment algorithm. Nowadays, partitioning and modularization are two main strategies for breaking down large ontologies into blocks or ontology modules respectively to align ontologies. This article proposes ONTEM as an effective alignment method for large-scale ontology based on the ontology entities extraction. This article conducts a comprehensive evaluation using the datasets of the OAEI 2018 campaign. The obtained results are promising, and they revealed that ONTEM is one of the most effective systems.

Os resultados evidenciam que a padronização e interoperabilidade em sistemas de informação, sejam eles relativos às bibliotecas ou às organizações de saúde, são de extrema importância por possibilitar a troca e o compartilhamento de informações dentro e fora das organizações, além de tornar mais eficientes os fluxos e processos informacionais.

Interoperable Law Enforcement. Cooperation Challenges in the EU Area of Freedom, Security and Justice

At present EU institutions and agencies as well as national legislators have ambitious agendas on law enforcement authorities’ access to interoperable information systems, which have become a defining feature of the AFSJ. They are the most advanced form of information exchange, conferring direct information access to competent authorities. Interoperable information systems are meant for the exchange of raw material for investigation purposes, which at a later stage could become evidence at trial. Interoperable information systems challenge existing cooperation dynamics and redefine the role of the actors involved. In fact, it is questionable whether mutual recognition and harmonisation, which have been considered the cornerstone of judicial cooperation in both civil and criminal matters for many years, can describe alone integration dynamics in law enforcement cooperation, particularly with reference to information sharing. This paper appraises whether, and to what extent, law enforcement access to and use of interoperable information systems constitute new modes of law enforcement cooperation in the EU AFSJ. It closely considers actors and/or factors which either hinder or foster such developments to assess what would be the implications of such a paradigm change in information management.

THE INTEROPERABILITY OF EUROPEAN INFORMATION SYSTEMS FOR BORDER AND MIGRATION MANAGEMENT AND FOR ENSURING SECURITY

The European Union has been exposed to an increase in illegal migration in recent years. With the migration, the threat of terrorist acts increased, which contributed to reducing the sense of internal security of citizens. The EU citizens expect more effective external border controls and more efficient migration management. Such challenges are addressed by the interoperability of European information systems for border management and migration, as well as ensuring security of the EU. A key element of interoperability is the adaptation of current systems and the development of new ones, especially in the technical aspect. In addition to legal, organizational and logistic activities, it is a key element of the entire system of activities of European institutions and agencies.

THE IMPLEMENTATION OF TECHNICAL INTEROPERABILITY MODELS IN LARAS VERSION 1.0 DIGITAL LIBRARY APPLICATIONS:A CASE STUDY IN THE CENTER FOR SCIENTIFIC DOCUMENTATION AND INFORMATION – INDONESIAN INSTITUTE OF SCIENCES

This study aims to find out models implementation of the technical interoperability applied and developed on the Digital Library Applications of the Library and Archive Analysis System version 1.0 (LARAS v 1.0) by the Center for Scientific Documentation and Information-Indonesian Institute of Sciences (PDII-LIPI). The other goal of this study is to determine why PDII-LIPI tries to develop LARAS v 1.0 and has changed the previous application of WINISIS. This study was done by using a case study method with qualitative approach. Data was collected by documents analyses and in-depth interviews. This result of the study shows that LARAS v 1.0 was created by developers at PDII-LIPI to avoid the obsolescence of information and technology communication (ITC), in this case, is the digital library application. In fact, the conflicts between the developers and the librarians in developing LARAS v 1.0 still exist. Models implementation of technical interoperability applied to LARAS is a combination of several levels of Level of Information System Interoperability (LISI) model. Nevertheless, in practice, LARAS v 1.0 is still not perfect, especially from the point of view of system development of metadata, encoding, communication protocol, databases, and indexing.

TRANSDISCIPLINARY SYSTEM OF SUPPORTING STUDENT YOUTH ACTIVITIES

The article focuses on the aspects of the realization of the young scientists constitutional right on the freedom of scientific creativity in the process of the implementation of research projects by providing access to modern achievements in science and technology. To solve this problem, it is proposed to create a transdisciplinary system of supporting the educational and research activities of the student youth by means of the software platform "Transdisciplinary Educational Dialogues of Application Ontological Systems". Cognitive IT software tools TODAOS provide the formation of transdisciplinary "prisms of knowledge", which are network ontological representations of the results of educational activities of student youth, semantically related to the network ontological representations of scientific and technical products of fundamental and applied researches of institutions of NAS of Ukraine and contextual connectivity indexes with thematically related scientific information, Ministry of Education’s curricula, and educational and methodological materials based on the interoperability and integrativeness of knowledge-oriented information resources and systems created in different formats and standards and technologies.

A study on the factors affect to technological adoption of e-Government Information System interoperability in Vietnam

Information system interoperability has an important role for e- Government development, specially in term of Public management information system. Each country has its own strategy in ensuring interoperability in information system. Nowadays, archiving interoperability among information system is very complex task. In developing countries, the building information system ensuring interoperability in public organizations is limited and ineffective. Moreover, without deeply understanding and determinance on interoperability dimensions, it will become a challenge for interoperability and E- Government implementation. Therefore, this study aims to investigate and analyze the interoperability factors which affect the adoption of Vietnam e-Government Information Systems interoperability. Moreover, data was gathered using survey through distributing questionnaires to the employees of IT departments in Vietnam public organizations. The data was analyzed through the technique of Structural equation modeling (SEM). The result shows that Risk Management, Collaboration and Coordination, Technical Expertise have significantly influence on Interoperability adoption in Government Information System in Vietnam.

Guiding interoperable electronic health records through patient-sharing networks

Effective sharing of clinical information between care providers is a critical component of a safe, efficient health system. National data-sharing systems may be costly, politically contentious and do not reflect local patterns of care delivery. This study examines hospital attendances in England from 2013 to 2015 to identify instances of patient sharing between hospitals. Of 19.6 million patients receiving care from 155 hospital care providers, 130 million presentations were identified. On 14.7 million occasions (12%), patients attended a different hospital to the one they attended on their previous interaction. A network of hospitals was constructed based on the frequency of patient sharing between hospitals which was partitioned using the Louvain algorithm into ten distinct data-sharing communities, improving the continuity of data sharing in such instances from 0 to 65–95%. Locally implemented data-sharing communities of hospitals may achieve effective accessibility of clinical information without a large-scale national interoperable information system.

Effect on VA Patient Satisfaction of Provider's Use of an Integrated Viewer of Multiple Electronic Health Records.

To examine associations between patient perceptions that their provider was knowledgeable of their medical history and clinicians' early adoption of an application that presents providers with an integrated longitudinal view of a patient's electronic health records (EHR) from multiple healthcare systems. This retrospective analysis utilizes provider audit logs from the Veterans Health Administration Joint Legacy Viewer (JLV) and patient responses to the Survey of Patient Healthcare Experiences Patient-Centered Medical Home (SHEP/PCMH) patient satisfaction survey (FY2016) to assess the relationship between the primary care provider being an early adopter of JLV and patient perception of the provider's knowledge of their medical history. Multivariate logistic regression models were used to control for patient age, race, sex education, health status, duration of patient-provider relationship, and provider characteristics. The study used responses from 203,903 patients to the SHEP-PCMH survey in FY2016 who received outpatient primary care services from 11,421 unique providers. Most (91%) clinicians had no JLV utilization in the 6months prior to the studied patient visit. Controlling for patient demographics, length of the patient-provider relationship, and provider and facility characteristics, being an early adopter of the JLV system was associated with a 14% (adj OR 1.14, p < 0.000) increased odds that patients felt their provider was knowledgeable about their medical history. When evaluating the interaction between duration of patient-provider relationship and being an early adopter of JLV, a greater effect was seen with patient-provider relationships that were greater than 3years (adj OR 1.23, p < 0.000), compared to those less than 3years. Increasing the interoperability of medical information systems has the potential to improve both patient care and patient experience of care. This study demonstrates that early adopters of an integrated view of electronic health records from multiple delivery systems are more likely to have their patients report that their clinician was knowledgeable of their medical history. With provider payments often linked to patient satisfaction performance metrics, investments in interoperability may be worthwhile.

Information system interoperability maturity model

&#x0D; &#x0D; &#x0D; &#x0D; Management of higher education (HE) cannot run if not yet have technological resources that can meet the needs of the campus community and stakeholders. The focus of this research was to look beyond the use of information systems (IS) of universities in Kopertis III Jakarta on the maturity level of data interoperability, software, communication, and physical IS. Using the Information System Interoperability Maturity Model (ISIMM), this study resulted in an average level of university located at level 3 (Collaborative) indicating the relationship between data was wider to facilitate IS, logical data model was shared and used in the data exchange process and no separation or the data sharing impacts on the easy exchange of information. The optimization of IS interoperability attributes (ease of access), develops ISIMM-based roadmap IS (planning), determines the main problem solving target (improvement), and improves the quality of IS based on importance level were some suggestions that university managers can make in order to advance IS.&#x0D; &#x0D; &#x0D; &#x0D;

Seamless recording of glucometer measurements among older experienced diabetic patients - A study of perception and usability.

Self-measurement and documentation of blood-glucose are critical elements of diabetes management, particularly in regimes including insulin. In this study, we analyze the usability of iBG-STAR, the first blood glucose meter connectable to a smartphone. This technology records glucometer measurements, removing the burden of documentation from diabetic patients. This study assesses the potential for implementation of iBG-STAR in routine care. Twelve long-term diabetic patients (4 males; median age of 66.5 years) were enrolled in the study. N = 4/12 reported diabetic polyneuropathy. Reported subjective mental workload for all tasks related to iBG-STAR was on average lower than 12 points, corresponding to the verbal code ‘nearly no effort needed’. A “Post Study System Usability Questionnaire”, evaluated the glucometer at an average value of 2.06 (SD = 1.02) on a 7-Likert-scale (1 = ‘I fully agree’ to 7 = ‘I completely disagree’) for usability. These results represent a positive user-experience. Patients with polyneuropathy may experience physical difficulties in completing the tasks, thereby affecting usability. Technologically savvy patients (n = 6) with a positive outlook on diabetes assessed the product as a suitable tool for themselves and would recommend to other diabetic patients. The main barrier to regular use was treating physicians’ inability to retrieve digitally recorded data. This barrier was due to a shortcoming in interoperability of mobile devices and medical information systems.

Interoperable Infrastructure and Implementation of a Health Data Model for Remote Monitoring of Chronic Diseases with Comorbidities

BackgroundThe future increase of chronic diseases justifies the development of telemedicine for following up patients outside of the hospital. However, current telemedicine applications are disease-specific whereas chronic diseases are often associated with comorbidities. MethodsWe show that the use of interoperability standards for telemedicine systems makes it possible to build a telemedicine platform (with several medical devices) that can be shared between several diseases workflows. To remotely follow up the patient's vital signs, health professionals need to access to the context description and the relevant background information. The implementation of a health data model that meets the needs of practitioners seems to be an appropriate solution to this problem. ResultsTo validate our architecture model of telemedicine application, we conducted various communication tests of vital signs to prove the interoperability of the patient system. The second experiment, we have developed one HL7 CDA document which collects several vital signs to a medical data exchange system among healthcare providers. This led us to propose a telemedicine application model, which is not only in conformity with the Health Information Systems Interoperability Framework (HIS-IF) of the “Agence des Systèmes d'Information Partagés de Santé” (ASIP), but also constitutes a proposed extension of this framework to the patient's home. ConclusionFor the remote monitoring of patients with multiple chronic conditions, we developed a generic architecture that allows different telemedicine applications associated with specific diseases to share a common technical platform. This work was to propose at first, a health data model for the patient's vital signs, and, on the other hand second, a study of communication standards to achieve an interoperable system.

Connecting Personal Data of Third Country Nationals: Interoperability of EU Databases in the Light of the CJEU's Case Law on Data Retention

On 12 December 2017, the EU Commission presented a proposal on the interoperability of EU large-scale Information Systems. The proposal seeks to enable all centralised EU databases for security, border and migration management to be interconnected by 2020. The underlying IT systems retain data of Third Country Nationals (TCNs), namely travellers, applicants for international protection, information relating to visa applications or data on missing persons and criminals. With the proposal, the Commission seeks to create new possibilities to exchange information, manage migration challenges and to enhance the Union’s internal security. The interconnectivity of databases would introduce fundamental changes to the current structure of EU IT-systems and requires careful consideration and assessment of compliance with EU data protection standards. This also means that access to information in an interoperable system must be strictly aligned to the access rights of the underlying databases and that requesting authorities only obtain the data that they are authorized to access. With interoperability, data once held in silos would be retained in three new centralized databases and would be more easily accessible, also for the prevention, investigation and prosecution of crime. Where criminal investigations previously required multiple searches in separate databases, this cascading safeguard shall progressively be abandoned to streamline access to personal data by law enforcement authorities. Despite simplified access conditions, this would require new types of processing operations for which the interoperability proposal does not provide a legal basis. During recent years, several judgments of the Court of Justice of the European Union (CJEU) have highlighted the difficulty of striking a proper balance between the fundamental rights to privacy and data protection, enshrined in Article 7 and 8 of the Charter of Fundamental Rights of the European Union (EU Charter) with an increased demand for security and the surveillance of potential criminals. The Court repeatedly pointed out the need to strike a fair balance between these (allegedly) competing interests and emphasised that law enforcement authorities should not be granted access to personal data without prior authorization. Using the CJEU’s judgments as vehicle and considering the assumption that TCNs risk to become subject to data retention measures in a disproportionate manner, the following analysis seeks to assess both existing EU databases and their foreseen interoperability against the requirements established by the Court in order to evaluate their (in)-compatibility with the fundamental rights standards enshrined in the EU Charter.

E-Cohesion maturity: How to measure the efficiency of digital cohesion policy

This paper focuses on the maturity of e-government services on the domain of European fund management, to explore the measurability of potential efficiency gains.&#x0D; The practical relevance of the topic is that the current European legislation prescribes that Member States shall offer electronic fund management services to beneficiaries to foment the efficient use of European Structural and Investment Funds. The main driver of this concept is the reduction of administrative burdens which can be achieved by the Europe-wide utilization of paperless fund management tools and by harnessing the interoperability of information systems. In the scientific discourse, the above concept is labelled as “e-Cohesion”. However, the legislation sets quite broad requirements for its implementation, so the e-Cohesion landscape and the intended efficiency gains may appreciably differ from country to country. The exploration of this “digital efficiency divide” offers a new relevant research opportunity. Therefore, this article is dealing with the measurability of efficiency of e-tools to methodologically support Member States in the realization and fine-tuning of their national e-Cohesion concepts.&#x0D; It is presented in this paper that the level of potential efficiency gains is connected to e-government readiness, i.e. the maturity of e-Cohesion systems. The paper, therefore, systematically reviews the relevant e-Government literature on the issue of maturity. Based on this, it aims to identify the most important models and methodological elements which address the main attributes of e-Cohesion to pave the way for further empirical research and the creation of an e-Cohesion-specific maturity model.

Model of Interoperability of Multiple Different Information Systems using SOA Middleware Layer and Ontological Database on the Cloud

The exponential evolution of technology and the environment surrounding the information systems (IS) forces companies to act quickly to follow the trend of business workflows with the use of high computer technologies and well adapted to the needs of the market. Currently, the performance of information system is considered a problem, we must intervene to make them more agile and responsive to better support the strategy of the company. The exchange and communication is a must between information systems to address these issues and new requirements, businesses are looking to integrate and interact even their information systems to interconnect applications. Interoperability is essential between information systems, it promotes alignment between the company’s business strategy and IT strategy while respecting the existing technical heritage of the company. The interoperability solutions between information systems face major problems since the SI is independently developed and designed differently and that solutions must meet certain criteria, namely, autonomy, scalability and resolve trade problems of data. The MDA approach is the most suitable solution to our problem because it ensures a degree of independence between the logic the company’s business and technology platform. Moreover, oriented architecture SOA service is used in this sense, it encapsulates the components of the information system into editable and reusable service. We want through this article to contribute to the development of a model for interoperability of several different IS, founded on a middleware layer compound of services according to the architecture SOA. The special feature of our model is that it uses an ontological database in the Cloud that will store concepts exchanged among interconnected IS and uses several transformation layers, integration, homogenization and adapting services.

Chile's National Center for Health Information Systems: A Public-Private Partnership to Foster Health Care Information Interoperability.

Despite the continuous technical advancements around health information standards, a critical component to their widespread adoption involves political agreement between a diverse set of stakeholders. Countries that have addressed this issue have used diverse strategies. In this vision paper we present the path that Chile is taking to establish a national program to implement health information standards and achieve interoperability. The Chilean government established an inter-agency program to define the current interoperability situation, existing gaps, barriers, and facilitators for interoperable health information systems. As an answer to the identified issues, the government decided to fund a consortium of Chilean universities to create the National Center for Health Information Systems. This consortium should encourage the interaction between all health care stakeholders, both public and private, to advance the selection of national standards and define certification procedures for software and human resources in health information technologies.
