- 2011
-
Konferensbidrag (refereegranskat)abstract
- Based on some identified problems and challenges to the current healthcare system, this paper proposes architecture for developing e-health system to meet the challenges and resolve some problems. The architecture is based on a solid theoretical model of human activity, and it has properties such as sustainability, generality, and expandability. We demonstrate the properties of the architecture through an ongoing research project. We concluded that this architecture can be widely used to integrate various small scale applications of e-health systems and to resolve some current design problems such as interoperability and knowledge sharing.

A sociocybernetic approach to information systems design
- 1998
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study has focused on the problems associated with the design of computer based managment Information Systems (IS) and especially on how to integrate the design, use and embedded social context into one coherent framework. The term IS is used in this study to broadly refer to areas such as Decision Support Systems (DSS), Human Computer Interaction (HCI) and Computer Supported Co-operative Work (CSCW). By viewing design activities as a social interaction process among designers and users and their social context, the study aimed to develop: 1. A socio-cybernetic and social-psychological theory of IS development and to enlighten the relationship between the IS design activities, IS use activities and embedded societal context; 2. A practicable method, called a "feedback learning strategy", for conducting IS design based on socio-cybernetic and social-psychological theory. This study has been conducted by generalisation, theoretical analysis and prototyping. A multiple disciplinary approach has been taken encompassing IS design based on activity theory, cybernetics, sociology, psychology, decision theory, and systems design theory (participatory design, prototyping).

Tidskriftsartikel (refereegranskat)abstract
- A principal problem of information systems (IS) development today is how to integrate the work activity and social context of users into the IS which is being designed. This paper aims to delineate a sociocybernetic approach which enlightens the relationship between IS design activity, use activity, and the embedded social context. First and second order cybernetics are employed as a general skeleton or structure for conducting the sociocybernetic approach. Approaches from social autopoiesis theory and activity theory are introduced respectively, to provide the skeleton of cybernetics with flesh and blood elements of real problems. An emerging conceptual body resulting from an organic integration of the cybernetic structure and social-psychological elements which demonstrates the relationship between IS design activity, use activity, and embedded social context is presented.

A Sociocybernetic Model of Sustainable Social Systems
- 2009
-
Konferensbidrag (refereegranskat)abstract
- The ongoing economic crisis world around has asked for a theoretical understanding and deep analysis of what have been wrong in our economic system in specific and social system as whole. Discussions in many forums and mass media have mostly focused on a level of first order casual-effects such as bank and credit system in relation to house loans and car industries, and where and how much the stimulating packages should be distributed, etc. This is what I called a liveability level problem. A second order understanding of fundamental systems structure and social subsystems relationships however, have not been much addressed properly. This is what I called the sustainability problem. This paper will propose an epistemological model based on cybernetic feedback principle and the Activity Theory to interpret the second order problems that deeply embed in our social-economic system structure. So the liveability and sustainability are coherently discussed within a socio-cybernetic system. The first part of the paper introduces shortly principles of feedbacks from cybernetics, especially understanding the behaviours of positive and negative feedbacks. Then, the Activity Theory and related concepts from social autopoietic theory are introduced. The aim of introducing those concepts is to provide the basic elements/components to the construction of a double-loops feedback model in the second part. In the last, the current economic crisis is interpreted based on the constructed model, to verify the usability of the proposed model.

A Sustainable Information System for e-home Services
- 2004
-
Konferensbidrag (refereegranskat)abstract
- E-home related home-services (including homecare and home healthcare) in China is urgently needed. The population of aged people over 80 is increasing 5% every year in China, and to year 2050, one fourth of whole population or 0.4 billions people in China are aged staying at home. Meanwhile the government cannot afford with a national elderly care system like most western countries as Sweden. This is because China has had one-child/one-family policy since 1970’s, and this radical policy has made China step in aged society very quickly within only 20 years, while the same process took 40-80 years in western countries. Even worse, China becomes aged society when the country is still poor and under developing with GDP per capita less than 1000$, comparing to western countries with 5000 – 10000 $ when they became aged society. E-home provides China with a unique, and maybe the most effective solution to the problem. By applying effective IT&C at home, elder people are facilitated to manage their own daily life. If needed, they can always call help from their collective service centre that is located in their resident area and the collective service centre can provide with both homecare (cleaning, shopping, reparation, baby care etc.) and home healthcare (legitimate medical care). Elder people can be also monitored (if wished by all partners) both at home and out door by bearing sensors that can send singles directly to related care providers (including their children and relatives if wished). E-home will greatly increase the security of elder people, release great worry from both their children and elder people themselves, and can be afford by most people. However, e-home is more than just a technical problem, and it needs a systemic way and social-psychological study how to design e-home system. In the end, e-home system must provide with needed services to residents. I will introduce IMIS project ´Integrated Mobile Information System for Home Healthcare’ financed by Swedish Agency for Innovative Systems (VINNOVA). This project will continue to 2006, and one of the outputs will be a sustainable software platform which is based on a systemic study of social psychological factors involved in the home healthcare. I will provide with some Swedish experiences and the so called ‘Scandinavia Approach’ in conducting such complex system to my colleagues in China, and I hope the IMIS project will be also developed in China based up on some feasibility and desirability studies with some Chinese colleagues.

Activity System Theory Approach to Healthcare Information System
- 2004
-
Konferensbidrag (refereegranskat)abstract
- Healthcare information system is a very complex system and has to be approached from systematic perspectives. This paper presents an Activity System Theory (ATS) approach by integrating system thinking and social psychology. First part of the paper, the activity system theory is presented, especially a recursive model of human activity system is introduced. A project ‘Integrated Mobile Information System for Diabetic Healthcare (IMIS)’ is then used to demonstrate a practical application of the Activity System Theory especially in constructing healthcare information system. Our conclusion is that the activity system model can provide the service system designers with a comprehensive and integrated framework for designing healthcare information system in specific, and for designing various kinds of service systems in general.

Activity Theory Ontology for Knowledge Sharing in E-health
- 2010
-
Konferensbidrag (refereegranskat)abstract
- Knowledge sharing has become an imperative and challenging issue in the E-health field for improving total quality of services. However, since the E-health subject is a multi-disciplinary and cross-organizational area, to have shared concepts, vocabulary plus a specification of its intended meaning, namely an ontology, has been an obstacle to develop e-health system. We will in this paper propose a knowledge sharing ontology on the basis of Activity Theory. We believe that Activity Theory can provide high level and rich ontology for the developers of E-health system to encompass the multi-disciplinary and cross-organizational knowledge. We validate our approach in the end by demonstrating our project IMIS (Integrated Mobile Information System for Healthcare) that uses the activity theory as ontological architecture for the construction of the whole system.

An Organic View of Prototyping in Information System Development
- 2014
-

Konferensbidrag (refereegranskat)abstract
- This paper presents an organic view of prototyping for managing dynamic factors involved in evolutionary design of information systems (IS). Those dynamic factors can be caused by, for example, continuing suggestions from users, changes in the technologies, and users-designers learning related stepwise progresses. Expanding the evolutionary prototyping to ‘start small and grow’, the organic view of prototyping proposes two prerequisites to do so, namely 1) a sustainable and adaptive ‘embryo’ – an organic structure of the future system, and 2) an embedded learning and feedback management that the actors of the system (users, designers, decision makers, administrators) can communicate with each other. An example of eHealth system design demonstrates how the prerequisites can be implemented.

Tidskriftsartikel (refereegranskat)abstract
- This paper proposes an epistemological model based on cybernetic principles and activity theory to interpret two levels of problems that are intertwined in our social-economic system, namely the liveability and sustainability problems. In the first part of the paper, important principles and concepts from related fields of cybernetics and activity theory are introduced for later construction of a model. In the second part, a model is constructed based on the introduced concepts. To validate the proposed model, the current economic crisis is studied in the third part. An important contribution of the proposed model is a theoretical understanding of the two levels problems, and how to construct macro social-economical policies to avoid similar crisis in the future.

Developing a Semantic Web Services for Interoperability
- 2005
-
Konferensbidrag (refereegranskat)abstract
- This paper deals with the design problems in healthcare information systems on how to adapt to dynamic factors and diversities so as to reach the interoperability between healthcare actors. Those dynamic factors and diversities are caused by, for example, constant suggestions from users, changes in the applied technologies, and after-learning related stepwise progresses. We suggest applying Web services technology, especially the idea of Semantic Web to tackle the problem of diversity in healthcare branch. In order to tackle the problem of dynamic changes during the design process, we suggest an evolutionary design methodology based upon an organic development metaphor – embryonic prototyping approach (EmA). We demonstrate our idea by the project IMIS that is to design a semantic Web service for the diabetic healthcare.

Tidskriftsartikel (refereegranskat)abstract
- This paper will approach the nature of system development based on dialectical thinking. To conduct this approach, the paper is divided into three parts. In the first part, the concept 'contradiction' is introduced in the context of dialectical thinking. In the second part,'systems development' is discussed in terms of contradiction in the Activity Theory. And in the last part,'information systems development' is presented as an example to demonstrate how information systems are developed in the light of this dialectical approach.

e-Health – Challenges and Approaches
- 2010
-
Konferensbidrag (refereegranskat)abstract
- Abstract: e-Health has been one of the most expected IT (information technology) applications just like e-Business, e-Learning, e-Government, and e-Democracy. However, e-Health has not reached the expected scale of use IT. There are challenges especially involved in healthcare sectors that are so different from other sectors. I will stress those challenges and suggest some approaches to meet the challenges from my past 10 years experience as a researcher in this area. I hope this will provide with researchers, entrepreneurs, and practitioners some hints when e-Health is the target area.

Embryonic approach to the development of information systems

Tidskriftsartikel (refereegranskat)abstract
- Prototyping in information systems (IS) development has recently shown increased benefits. In principle, the prototyping process provides users with more opportunities to improve their work, to verify that their needs are provided for, and that the terms used in the interface of the designed system are consistent with those in use in their work. As a result, they should be highly motivated to participate in an IS development process. However, certain drawbacks inherited from traditional prototyping in industrial production could limit the use of this approach in IS development. Some problems are identified in this paper, such as: (1) product-oriented thinking; (2) feedback delay; (3) the preoccupation of designers with respect to the experimental approach; (4) problems arising from the users' participation being indirect, and (5) negative attitudes towards contradiction. This paper proposes an organic approach, the `Embryonic Approach' (EmA), in order to explore the full potentialities of prototyping in IS development. This approach is based on two fundamental elements; an adaptive and expandable kernel-structure, and a built-in communication mechanism.

Functions For eHealth Communication Systems Design
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The design of eHealth systems calls for a clear needs analysis and functions based on the users’ perspective. However, this is often the most difficult part of designing eHealth service systems, because of the diversity of users and diversified needs. This paper provides a general mapping and overview of the basic functions of eHealth systems identified through two studies: (1) a comprehensive study of the resource book of eHealth projects under the European Sixth Framework programme (FP6), and (2) a theoretical study based on the framework of Activity Theory. The first study provides the eHealth system designers with an overview of a number of important and particular functions that the users/citizens need in order to get good services; while the second study presents a fundamental ‘skeleton’ and architecture for providing those particular functions in an orderly and coherent system.

Guide to REgional Good Practice eHealth
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report shows the result of the work of IANIS+ eHealth work group (WG). The WG has collected regional eHealth experiences from around Europe through a number of activities: • Regional eHealth case studies of which 17 (from 15 regions) are shown in this report • Four joint meetings of the group of which one was a policy seminar with invited guests from the EU Commission, relevant organisations in the field of eHealth and regional authorities • A meeting with the European Commission DG Information Society & Media, Unit H1 eHealth • Collaboration with the eHealth network within the organisation Assembly of European Regions (AER) • Attendance in recent major eHealth conferences: · Personal Health Systems arranged by the European Commission when launching the eHealth part of the 7th Framework Programme, 11-12 February 2007 · The EU-US eHealth Policy Workshop, 10 May 2007 · The final conference of the INTERREG IIIB project Baltic eHealth, 21-22 May 2007 • eHealth seminars at IANIS+ annual conferences in Blekinge 2006 and Bilbao 2007 The innovation perspective of eHealth in the regions has been the focus for the IANIS+ eHealth WG. Regional diversity regarding strategies, policies, and action plans for eHealth can act as a driving factor for successful eHealth projects, but leads also to challenges for interoperability, standardisation, integrity and security. It is important to learn from others. It may be about how to choose the right technology or what methods to use for implementation. Depending on what area of eHealth, there are numerous projects and up-and-running services from which we can learn. Not to forget there are also many experiences from unsuccessful trials. Even if an eHealth solution has failed in one setting, it can be a success under different circumstances. The aim of the IANIS+ eHealth Working Group was to share experience between regions belonging to the network, and bring up some issues of good practice for regional eHealth implementation. Projects brought up in the IANIS+ working group are projects in there own rights, with pros and cons. The projects cover different perspectives and types of eHealth. Some were difficult to evaluate while others are valuable comparable experiences from different settings and circumstances. In any case, we can learn something from all the cases as examples from reality and as a complement to formal evaluations and scientific studies of eHealth. We would rather use the term good practice than best practice. There is always something good to learn from others while there is hardly any best practice that works under every circumstance.

A new Software Framework for Heterogeneous Knowledge Sharing in Healthcare system
- 2016
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Today’s demand for healthcare is dramatically increasing as the factor of the aging population and expectations growing during the past few years. This leads to the need of substantial healthcare services with innovative technologies developed from both industry and academia. Designing an efficient healthcare system is however a sophisticated process due to different research issues with the requirement for the provision of high-quality healthcare services. Connected to this requirement, the focus of many studies done so far is widely laid on a well-known problem called knowledge sharing. In recent years, knowledge sharing raises as one of the most demanding applications with references to the dynamic inter-activity among different healthcare actors and the complex data structures involved in this application. Suitable solution approach to knowledge sharing can enhance the efficiency of healthcare delivery, and thus improving the quality of healthcare services. The corresponding development tasks can be accomplished by using different methodologies such as analytical approaches, simulation experiments and practical measurements on the real healthcare system.In our work, the problem of heterogeneous knowledge sharing in the healthcare system is considered. Here, the heterogeneous aspect is expressed in terms ofdifferent healthcare actors and the associated characterizations. To do this, we suggest a new software framework, which mainly consists of three components. The first component is about the ontology based activity theory, which is used to scientifically represent the healthcare actors together with their relationships and interactions. The second component refers to an overlay decision maker, which is responsible for dealing with the decision-making activities such as appointment scheduling. Its advantage is to jointly consider various healthcare parameters and different algorithms for decision-making purposes. Based on these two components, the third component provides the theoretical models to conduct the numerical analysis and performance evaluation on the particular healthcare service.

- Knowledge sharing has become an important issue that challenges the efficient healthcare delivery in eHealth system. It also rises as one of the mostdemanding applications with reference to dynamic interactivities among various healthcare actors (e.g. doctors, nurses, patients, relatives of patients). Inthis paper, we suggest an activity theory based ontology model to represent various healthcare actors. The goal of the suggested model is to enhance inte-ractivities among these healthcare actors for conducting more efficient knowledge sharing, which helps to design eHealth system. To validate the feasibilityof suggested ontology model, three typical use cases are further studied. A questionnaire based survey is carried out and the corresponding survey resultsare reported, together with the detailed discussions.

eHASS : A Smart Appointment Scheduling System for eHealth
- 2016
-
Konferensbidrag (refereegranskat)abstract
- In the eHealth system, the appointment scheduling is an important task for the delivery of healthcare service among different healthcare actors. The key procedure is to do the decision making on the selection of suitable appointments between the care providers and the care receivers. The appointment decisionis a sophisticated problem in terms of how to efficiently deal with various parameters of involved healthcare actors. To solve this problem, we suggest a smart system called eHealth Appointment Scheduling System (eHASS). eHASS takes into account both heterogeneous aspects and interoperability requirements of eHealth system. As such, eHASS is capable of jointly considering various appointment characterizations and decision making algorithms for conducting appointment scheduling. The paper reports the eHASS architecture as well as the related work-in-progress.

Heterogeneous Knowledge Sharing in eHealth : Modeling, Validation and Application
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Knowledge sharing has become an important issue in the eHealth field for improving the quality of healthcare service. However, since eHealth subject is a multidisciplinary and cross-organizational area, knowledge sharing is a serious challenge when it comes to developing eHealth systems. Thus, this thesis studies the heterogeneous knowledge sharing in eHealth and proposes a knowledge sharing ontology. The study consists of three main parts: modeling, validation and application.In the modeling part, knowledge sharing in eHealth is studied from two main aspects: the first aspect is the heterogeneous knowledge of different healthcare actors, and the second aspect is the interactivities among various healthcare actors. In this part, the contribution is to propose an Activity Theory based Ontology (ATO) model to highlight and represent these two aspects of eHealth knowledge sharing, which is helpful for designing efficient eHealth systems.In the validation part, a questionnaire based survey is conducted to practically validate the feasibility of the proposed ATO model. The survey results are analyzed to explore the effectiveness of the proposed model for designing efficient knowledge sharing in eHealth. Further, a web based software prototype is constructed to validate the applicability of the ATO model for practical eHealth systems. In this part, the contribution is to explore and show how the proposed ATO model can be validated.In the application part, the importance and usefulness of applying the proposed ATO model to solve two real problems are addressed. These two problems are healthcare decision making and appointment scheduling. There is a similar basic challenge in both these problems: a healthcare provider (e.g., a doctor) needs to provide optimal healthcare service (e.g., suitable medicine or fast treatment) to a healthcare receiver (e.g., a patient). Here, the optimization of the healthcare service needs to be achieved in accordance with eHealth knowledge which is distributed in the system and needs to be shared, such as the doctor’s competence, the patient’s health status, and priority control on patients’ diseases. In this part, the contribution is to propose a smart system called eHealth Appointment Scheduling System (eHASS) based on ATO model.This research work has been presented in eight conference and journal papers, which, along with an introductory chapter, are included in this compilation thesis.

Konferensbidrag (refereegranskat)abstract
- Abstract—eHealth is an emerging area that boosts up with advancement in Information and Communication Technology (ICT). Due to variety of eHealth solutions developed by different IT firms with no unified standards, interoperability issue has raised. In this paper, a case study in Blekinge County healthcare organizations has been conducted for understanding the contexts of eHealth interoperability issues. Then a peer-to-peer (P2P) model based on JXTA platform is implemented to solve the identified eHealth interoperability problems. According to the test result of the prototype, the suggested syntactic level interoperability among healthcare organizations has been achieved.

A Cloud Model for Interoperable Home-based Chronic Diseases Healthcare
- 2014
-
Konferensbidrag (refereegranskat)abstract
- Traditional hospital based care cannot meet all the needs of chronic diseases care in home, especially for elderly people. A new approach applying eHealth that supports interoperable health care is required. To find a way to meet the new needs, we firstly carried out a questionnaire to analyze current problems and needs in chronic disease care. Then we compared possible technical solutions and proposed a cloud model for the identified problems. This model would help chronic patients self-record and control their daily care data, communicate with other patients who have the similar situation. The proposed solution could be also used to integrate data from different healthcare providers for a cooperative work, namely in this paper as Home-based Chronic Diseases Healthcare (HCDH).

- Cloud computing in eHealth is an emerging area for only few years. There needs to identify the state of the art and pinpoint challenges and possible directions for researchers and applications developers. Based on this need, we have conducted a systematic review of cloud computing in eHealth. We searched ACM Digital Library, IEEE Xplore, Inspec, ISI Web of Science and Springer as well as relevant open-access journals for relevant articles. A total of 237 studies were first searched, of which 44 papers met the Include Criteria. The studies identified three types of studied areas about cloud computing in eHealth, namely (1) cloud-based eHealth framework design (n=13); (2) applications of cloud computing (n=17); and (3) security or privacy control mechanisms of healthcare data in the cloud (n=14). Most of the studies in the review were about designs and concept-proof. Only very few studies have evaluated their research in the real world, which may indicate that the application of cloud computing in eHealth is still very immature. However, our presented review could pinpoint that a hybrid cloud platform with mixed access control and security protection mechanisms will be a main research area for developing citizen centred home-based healthcare applications.

- The internet based social network has been applied to serve many social functions, such as democratic decision making, knowledge sharing, educa‐ tion, and healthcare. In this paper, we provide a prototype of virtual community designed for home-based chronic diseases healthcare. We studied the concept “community” from the activity theory model in order to design the prototype with a solid theoretical base. Then we conducted a questionnaire from healthcare recipients and interviewed healthcare providers to gather the requirements for the design of the community. With some user stories we described the requirements as use cases for our design and a conceptual prototype is built based on the requirements. This virtual community servers as a shared platform for all the stakeholders who are engaged in the healthcare activity. With this shared community platform, the interoperability problems of current healthcare systems can be moderated

Bokkapitel (refereegranskat)abstract
- Recently, the care of chronic disease has become a worldwide challenge. Although the healthcare domain has begun to adopt new ICT technologies such as the Internet of Things and cloud computing, it is still in its initial phase. In this chapter, the authors conduct a small-scale two-step case study of diabetes care in Blekinge, Sweden. The first step is intended to acquire insight into the actual care situation to improve the original conceptual model. In the second step, we validate the feasibility of the improved model working in real healthcare. The results show that the Internet of Things and cloud computing is acceptable by both healthcare providers and recipients for home-based chronic diseases healthcare with little concerns of security and privacy in the future. In our hybrid cloud model, hospitals and primary healthcare centers could continue using their own exciting databases as private clouds. The best approach for home-based healthcare data is to collect it by connecting the different devices directly and storing and processing them in public clouds. To realize this model in the future, we suggest that a professional IT healthcare education team should be created to support both healthcare providers and recipients.

- With the development of Internet, social networks get more and more popular, it brings us an idea of designing a virtual community for home-based chronic diseases healthcare. In this paper, we conduct a questionnaire to gather the requirements of the community and describe them with user stories. Afterwards, a conceptual prototype is developed based on the requirements. The proposed virtual community involves healthcare providers, healthcare recipients and other people relevant to the home-based healthcare into one platform. It will solve the interoperability problems of current healthcare systems, as well as provide a technical solution of home-based healthcare.

Cloud Computing for Achieving Interoperability in Home-based Healthcare
- 2017

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The care of chronic disease has become the main challenge for healthcare institutions around the world. As the incidence and prevalence of chronic diseases continue to increase, it is a big challenge for traditional hospital-based healthcare to meet requirements of patients. To meet the growing needs of patients, moving the front desk of healthcare from hospital to home is essential. Home-based healthcare for chronic disease involves many different organizations and healthcare providers. Therefore, there are interoperability problems for cooperation among the various organizations and healthcare providers to provide efficient and seamless home-based healthcare. This thesis aims to point out an appropriate technical solution to interoperability problems in home-based healthcare. There are different levels of interoperability, such as pragmatic, semantic and syntactic. We explored alternative solutions specifically for syntactic interoperability. We started to identify the interoperability problems among different healthcare centers by interviews and online surveys. Based on this empirical study, we mainly used two current techniques, namely peer-to-peer (P2P) networks and cloud computing, to design prototypes for sharing healthcare data. Comparing these two techniques, we found the cloud-based solution figured out most of the problems encountered in healthcare interoperability. To identify state of the art, and pinpoint the challenges and possible future directions for applying a cloud-based solution, a systematic literature review was carried out on cloud-based healthcare solutions. Based on the literature reviewed, we suggest a hybrid cloud model, with access controls and techniques for securing data, could be an acceptable solution for home-based healthcare in the future. This cloud model would work as a community for both healthcare providers and recipients, as well as other stakeholders, such as family members and other patients with similar symptoms. Then we conducted a questionnaire study with healthcare recipients and interviewed healthcare providers to gather the requirements for the design of the community. Based on the concept of ‘community’ from the activity theory model, we designed a prototype to demonstrate our proposed solution. Finally, we proposed the conceptual hybrid cloud model. In our hybrid cloud model, hospitals and primary healthcare centers could continue using their own databases as private clouds. For home-based healthcare data, we argued, the best approach is to store and process the data in public clouds. Healthcare recipients, as the owners of their health data in public clouds, should then decide who can access their data and the conditions for sharing. To evaluate this model, we conducted a two-step case study of diabetes healthcare in Blekinge, Sweden. We found that our improved hybrid cloud model will be feasible in the future for home-based healthcare, and it will benefit both healthcare providers and recipients.To apply this model in practice, we suggest that a professional IT healthcare education team should be created to support both healthcare providers and recipients.

Konferensbidrag (refereegranskat)abstract
- Nowadays, patient self-management is encouraged in home-based healthcare, especially for chronic disease care. Sharing health information could improve the quality of patient self-management. In this paper, we introduce cloud computing as a potential technology to provide a more sustainable long-term solution compared with other technologies. A hybrid cloud is identified as a suitable way to enable patients to share health information for promoting the treatment of chronic diseases. And then a prototype on the case of type 2 diabetes is implemented to prove the feasibility of the proposed solution.

Enhance Flexibility in Human Agent Interaction a Case Study on IMAS Agent System
- 2008
-
Konferensbidrag (refereegranskat)abstract
- Human Agent Interaction (HAI) is considered as a sub area in Human Computer Interaction (HCI), in which the computer systems are specified as agent systems. Computer agents are different from traditional Information Systems in aspects of autonomy, adaptivity, and persona when interacting with human users. The usability principles in HCI research should be refined to focus on agent special characteristics when designing agent systems. We argue that flexibility should be especially enhanced in such a case.
