CONCEPTUAL FRAMEWORK
Conceptual model can be defined a set of concepts and those assumptions that integrate them into meaningful configurations. Conceptual frame work is theoretical approach to study problem, which is scientifically based on the emphasis on selection, arrangement and classification of concept which deals within the study.
Conceptual is adapted for the present study is based on Ludwig von Bertalanffy's general
system.
GENERAL SYSTEM THEORY (Conceptual frame work based on betalanffy's 1968)
Open system are those in which there is an exchange of energy material, information with environment. These are characterized by
Ø Input of energy into system
Ø Through put during which the system process, changes, recognizes imported energy.
Ø Output of energy into environment in the form of goods, services, intellectual products.
Ø Feedback by which apart of output returns to the system.
INPUT:
The first component of the system is input, which is the information, energy or matters that enters the system. For a system to work well input should to contribute to achieve the purpose of the system. It refers to demographic data and knowledge on the protein energy malnutrition. These factors were taken into consideration on input for evaluation the effectiveness in bringing out the change in knowledge level of post natal mothers.
THROUGH PUT:
The action needed to accomplish the desired task, to achieve the desired task that is to assess the effectiveness of structured teaching programme on put of the study was the assessment of knowledge by pre test questionnaire, preparation of structured teaching on the importance/maintenance of menstrual hygiene. Validation of structured teaching, administration of post test questionnaire, evaluation structured teaching.
OUTPUT:
After the input and process, the system returns output to the environment, in an altered state the end results or product of system. Output vary widely depending on the type and purpose of system effecting environment, here output refers to knowledge of the puberty girls regarding the importance/maintenance of menstrual hygiene If the knowledge level are found to be inadequate, rectification can be done by strengthening the existing knowledge through continuous monitoring which is not under the preview of the study.
FEED BACK:
The process of communicating what found in evaluation of system. The feedback can be measured by output whether knowledge is adequate or structured teaching or not. The developed structured teaching will be considered the useful to update knowledge of puberty girls. If the knowledge is inadequate it refers that the systems input, throughput has to be re evaluated which is not included in the study.
