Application of Information Technology: Temporal Expressiveness in Querying a Time-stamp - based Clinical Database
Most health care databases include time-stamped instant data as the only temporal representation of patient information. Many previous efforts have attempted to provide frameworks in which medical databases could be queried in relation to time. These, however, have required either a sophisticated database representation of time, including time intervals, or a time-stamp-based database coupled w...
متن کاملQuerying Clinical Workflows by Temporal Similarity
The degree of fulfillment of clinical guidelines is considered a key factor when evaluating the quality of a clinical service. Guidelines can be seen as processes describing the sequence of activities to be done. Consequently, workflow formalisms seem to be a valid approach to model the flow of actions in the guideline and their temporal aspects. The application of a guideline to a specific pat...
متن کاملQuerying temporal clinical databases on granular trends
This paper focuses on the identification of temporal trends involving different granularities in clinical databases, where data are temporal in nature: for example, while follow-up visit data are usually stored at the granularity of working days, queries on these data could require to consider trends either at the granularity of months ("find patients who had an increase of systolic blood press...
متن کاملTime stamp based ECC encryption and decryption
Elliptic Curve Cryptography (ECC) provides a secure means of exchanging keys among communicating hosts using the diffie hellman key exchange algorithm. Encryption and decryption of texts and messages have also been attempted. In the paper on Knapsack over ECC algorithm, the authors presented the implementation of ECC by first transforming the message into an affine point on the EC, and then app...
متن کاملA Knowledge-Based Time-Oriented Active Database Approach for Intelligent Abstraction, Querying and Continuous Monitoring of Clinical Data
Query and interpretation of time-oriented medical data involves two subtasks: Temporal-reasoning--intelligent analysis of time-oriented data, and temporal-maintenance--effective storage, query, and retrieval of these data. Integration of these tasks into one system, known as temporal-mediator, has been proven to be beneficial to biomedical applications such as monitoring, therapy, quality asses...
