World Health Organization analysis system

The World Health Organization (WHO) promotes the use of an Anatomical Therapeutic Chemical (ATC) classification system for the collection and analysis of data on drug use. This was originally developed by Scandinavian authorities, and uses a combination of anatomical, therapeutic and chemical criteria to assign drugs to an individual class. The top-level categories, which are anatomically based, are listed in Table 3.2.

The mostly widely used chemistry mastery system in the world Developed at the University of Massachusetts, Amherst, class-tested by thousands of students, and used by over 200 institutions and 50,000 students, OWL is the most widely used system because it provides fiilly class-tested content in an easy to use system that has proven to be reliable for tens of thousands of students. OWL is also customizable, cross-platform, and available for intro/preparatory chemisu, general chemistry, organic chemistry, liberal arts chemistry, and allied health/GOB. The OWL Online Web-based Learning system provides students with instant analysis and feedback on homework problems, modeling questions, and animations to accompany select Brooks/Cole texts. With chemical and numerical parameterization, OWL offers thousands of questions. This powerful system maximizes the students learning experience and, at the same time, reduces faculty workload and helps facilitate instruction. A fee-based access code is required for access to the specific OWL database selected. OWL is only available for use within North America.
