Anatomical Therapeutic and Chemical Classification System (ATC)/Defined DailyDose (DDD)

The Anatomical Therapeutic and Chemical Classification System (ATC) divides drugs into different groups according to the organ or system on which they act and/or their therapeutic and chemical characteristics. The Defined Daily Dose (DDD) is the assumed average maintenance dose per day for a drug used for its main indication in adults. It is used to standardize the comparison of drug usage between different drugs or between different health care environments. (Administrative Order 2013-0025)

Philippine Standard Occupational Classification (PSOC)

The PSOC is a statistical classification of the different occupational groups of the working population, including the military workforce.

It serves the needs of statistical operations and activities, such as censuses and surveys, job placement and recruitment services, vocational training and guidance, immigration purposes and related activities.

It also provides a basis for manpower/educational planning and policy decision-making.
