The element of time buy kamagra soft 100 mg overnight delivery erectile dysfunction icd 9 code wiki, associated with clinical information can be identified as an important aspect in the delivery and automation of decision support that can be facilitated by Internet-based healthcare delivery 100 mg kamagra soft free shipping erectile dysfunction blogs forums. It has recently been reported that the element of time has not had its full potential exploited in terms of the benefits it can offer in medical decision support systems (Augusto, 2003a). Although Internet-based systems and medical decision support systems are slowly merging, consideration must also be given to the tools required to analyze time related information and give consideration as to how they can be incorporated into Internet-based healthcare delivery.

Although usually unconsciously, we need to make considerations on a daily basis regarding the preferred order that some of our activities have to be performed in, or for how long some of these activities will last. Frequently deadlines have to be met, such as at work we are constantly undertaking activities which have prescribed time limits, in our personal lives we engage in activities that are constrained by time; to collect children from school or to reach the supermarket before it closes. These activities sustain our perception of time ubiquity and provide a clear practical motivation behind the research in TR. The importance of addressing the way in which humans deal with time-related notions was identified in the 1970s as an important goal to be addressed by the Artificial Intelligence (AI) community as a step towards providing intelligent behavior from computing systems. Research in the area has been steadily increasing over the past two decades and as a result much understanding about the related problems has been gained and many techniques and associated tools are now available. An elementary issue relates to the temporal references to be used (hours, minutes, calendar Figure 3. Qualitative temporal relationships between durative and non-durative temporal references (a) interval-interval case (b) point-point case (c) point-interval case Copyright © 2005, Idea Group Inc. Copying or distributing in print or electronic forms without written permission of Idea Group Inc. Management and Analysis of Time-Related Data in Internet-Based Healthcare 39 dates, etc. Some of the more basic temporal frameworks are based either on time points, on intervals or on a combination of both. Figure 3 (a) depicts at an intuitive level, the possible meaningful situations two intervals can be in. Part (b) shows the two meaningful relative positions for two points, while part (c) shows the possible situations between a point and an interval. Explicit details of how the aforementioned can be integrated in a TR system can be found in Allen (1984) and Meiri (1991). Temporal references provide a way to directly represent situations involving different types of sequential or concurrent time-related concepts like states holding for a given period or events that can provoke a transition in the system from one state to the next one. Specific research has been focused on repetitive patterns that may be used to reason about processes (Cukierman & Delgrande, 2000). The durative time references included in Figure 3 are called intervals and rely on precise knowledge about their duration. However, it is usually the case that the knowledge available is not as precise as desired, for example, it may be known when an event started but not when it finished or vice versa; these are called semi-intervals (see Freksa, 1992). If for example the end of an interval is not known then it may be important to infer when, possibly within some boundaries, the point at which the semi-interval can be supposed to persist to (see Sadri, 1987; Augusto 2003b). It is impossible to give here a full coverage of all the subtleties involved in TR. We have introduced some basic concepts and invite the interested reader to review the following to obtain a more complete picture of the subtleties, challenges and benefits involved in using TR: Newton-Smith (1980); Shoham (1987); Sandewall (1994); Galton (1995) and Augusto (2001). Reflecting the many possible instances of time-related information in medicine there has been quite an intense research activity in the area during the last decade. See for example some of the special issues focused on the topic: Keravnou (1991); Keravnou (1996); Combi & Shahar (1997); Shahar & Combi (1999) and a more recent survey by Augusto (2003a). A long list of general activities has been identified as key initial steps in the process to provide explicit temporal awareness for systems related to medicine (Shahar, 1999). Determining bounds for absolute occurrences, some information may be missing, for example we know when some symptoms finished but not when they started. Hence it is possible by using other information to infer, at least within some time boundaries, the point in time at which the symptoms started.
