This thesis provides an answer to the question: How can proactive data mining of security events help prevent data breaches of credit card data in a PCI DSS compliant environment? The credit card environment is sketched and covers the three actors in a credit card transaction (Cardholder, Merchant and Banks). PCI-DD is discussed together with the various other standards created by the PCI Security Council. The concept data breach is elaborated on and 15 indicators are discussed which should notify a possible breach as early as possible. A method is created that consist of four steps (Identify Data, Map Indicators, Data Mining & Follow-up) that will assist organizations in preventing data breaches. Vulnerability management, by periodically performing vulnerability assessments is necessary for organizations to have a secure basis. An evaluation of the indicators and method concludes this research.

This study is part of the European FP7 ALIZ-E project. The goal of this project is to develop the theory and practice behind an embodied social robot that is capable of maintaining affective interactions with young users over an extended and possibly discontinuous period of time. The target audience of this research consists of young patients suffering from diabetes mellitus. In previous work on ALIZ-E, several activities have been developed that the user can carry out with the robot, such as playing a quiz, math game or imitation game. Research has shown that monitoring one’s diabetes by keeping a diary is beneficial to the child’s health on the short and long term. In this master thesis, we develop a new activity that allows a diabetic child to keep an online diabetes diary together with the robot. We evaluate this new activity by investigating the following research question: How can a robot contribute to the activity of keeping a web-based diary together with diabetic children? We present a comprehensive robot dialogue model that has two main foci: 1) supporting and motivating the child in the task of keeping a diary and 2) forming a bond between the child and the robot through personalized interaction. We tested the dialogue model by performing a pilot experiment in a real-world setting using a within-subjects design (N=6). The subjects were diabetic children between the ages of 9 to 12. Over the course of eleven days, they kept an online diary in which they logged their blood glucose values, carbohydrate intake, insulin dosages, exercise, emotional well-being and their daily activities. Every other day the children remotely connected to the robot, which they believed to be autonomous, and performed this activity together. The robot provided explanations where necessary; asked the child relevant questions and shared personal information to establish a social bond. We measured adherence by comparing the frequency of diary entries and the diary content between th

The purpose of this study was to assess the intrinsic and contextual data quality of the Dutch DBC Information System (DIS) database, which contains all data relevant to the healthcare reimbursements. The intrinsic data quality was examined from a process point of view by determining the organizational and technical issues negatively influencing the data quality. Focus here was on the Dutch hospitals. The contextual data quality was examined as the "fit for use" of these data to evaluate efficiency and patient safety performances of the hospitals. This is currently unexplored, although traditional datasets used for scientific research of these contexts are no longer properly available and alternatives have to be found. A qualitative research method was used for this research: eighteen field experts were interviewed in nineteen semi-structured expert interviews. The experts represented several relevant stakeholder groups such as the internal hospital administration, the DIS itself, internal and external hospital consultants and scientists specialized in efficiency or patient safety research. To structure the interviews and analyze the results, a data quality framework was constructed based on existing literature. The interviews were recorded and transcribed. These transcripts served as the resulting (qualitative) dataset and were analyzed with a grounded-theory approach. The results of these analyses indicated that several organizational and technical issues exist in the hospitals and the DBC system, negatively influencing the (intrinsic) DIS data quality. Most notably the issues pertain to the registration of the performed activities: the management of the hospital activity codes and aggregation to the national activity (ZA) codes used for DIS. Recommendations are provided to improve these issues and ultimately the DIS data quality. Despite the existing issues, the data are still suited for analysis, if used properly. For the evaluation of efficiency, the data have

In the last 25 years the demand for health care services has increased rapidly in The Netherlands. In the near future, health care expenses will rise even faster due to ageing and high labor costs. The deployment of IT as a method to save costs is widely accepted. In primary care, the first consultation point in health care, general research to this subject is still scarce. This research attempts to find out which factors determine the success of IT innovations in primary care. An extensive systematic literature review was chosen as a method to find theoretical evident for the construction of two frameworks, namely stage-oriented (FRAMEWORK A) and actor-based (FRAMEWORK B). After an interview round with practice experts FRAMEWORK B was enhanced, while FRAMEWORK A was discontinued. A second round of interviews focusing on the revised FRAMEWORK B resulted in large support by the experts, though improvements are needed. We conclude that the framework is a good starting point for innovators and researchers to use as a basic guide, while future research must help to extend the framework regarding the innovation type and perspective.

De samenwerking in de eerste lijn neemt gestaag toe. Ruim de helft van de Nederlandse huisartsenpraktijken werkt met andere eerstelijnszorgverleners, zoals apothekers, fysiotherapeuten en sociaal psychiatrisch verpleegkundigen, samen onder één dak. Tussen 2007 en 2009 is het aantal samenwerkingscontracten van huisartsen met andere eerstelijnszorgverleners met 5% toegenomen tot 43% en het aantal huisartsen dat met anderen onder één dak werkt met 8% tot 58%. Dit blijkt uit onderzoek van het NIVEL (Nederlands instituut voor onderzoek van de gezondheidszorg), dat is uitgevoerd met subsidie van het ministerie van VWS. Het ministerie wil de eerste lijn versterken zodat die zijn centrale rol in het Nederlandse zorgsysteem kan behouden. De achterliggende gedachte is dat samenwerking goed is voor de samenhang van de zorg en afstemming. De Monitor multidisciplinaire samenwerking verzamelt gegevens om bij te houden of er inderdaad meer samenwerkingsverbanden zijn gekomen binnen de eerst lijn. Verschillen NIVEL-onderzoeker Johan Hansen: “In 2007 zagen we al verschuivingen. Huisartsen waren vooral meer gaan samenwerken met apothekers, fysiotherapeuten en sociaal psychiatrisch verpleegkundigen. Deze trend heeft zich verder doorgezet. En deze samenwerking blijft in bijvoorbeeld achterstandswijken niet achter bij die in andere wijken. Ook zijn er regionale verschillen: in Groningen, Drenthe en Zuid-Limburg werken huisartsen het meest op één locatie met fysiotherapeuten en apothekers.” Patiëntgericht De samenwerking is vooral gericht op de zorg voor diabetes, COPD en astma, en hart- en vaatziekten. Hansen: “De samenwerking is wel patiëntgericht, maar meestal zijn patiënten of een patiëntenvereniging daar niet actief bij betrokken.” Als knelpunt in de samenwerking wordt de relatie met de zorgverzekeraar het meest genoemd. “We krijgen de indruk dat de financiering zoals geregeld door overheid en zorgverzekeraars wel insteekt op samenwerking, maar ook complex is en gefragmenteerd.
