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.

A General Architecture For Developing A Sustainable Elderly Care e-Health System
- 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 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.

Ingår i: Journal of Systems Science and Systems Engineering. - Beijing : Springer Science + business Media. - 1004-3756 .- 1861-9576. ; 13:No.4
-
Tidskriftsartikel (refereegranskat)abstract
- By integrating system thinking and social psychology, this paper presents an Activity System Theory (AST) approach to the platform design of e-service systems in general, and e-healthcare systems in specific. In the first part, some important principles of AST and a sustainable model of human activity system are introduced. Then a project ‘Integrated Mobile Information System for Healthcare (IMIS)’ is presented to demonstrate how to construct a comprehensive platform for various complex e-service systems based on the sustainable model of AST. Our research focused on the complex e-healthcare system in Sweden, and the results showed that the model of AST can provide the designers of e-service system with a comprehensive and sustainable platform for designing various kinds of e-service system

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.

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.

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.
