Determination of the relation between the people's 2D:4D finger lenghts' rate and people's bent to mathematical and social branches with professional system

One of the most affected areas of technology is health sector. Usage of technology in medical sector leads us perfect recognition of the disease even prevents wasting time and let medical interventions be done faster. Today, ranging from drawing blood sample from babies? capillaries to operating micro endoscopic neurosurgery by experienced doctors from miles away can be possible. Interaction of medical sector and computer technology is inevitable due to applications like above. Many research studies show us a number of cases caused by death due to doctor's oversight, lack of experience of doctor or lack of in-service training of personnel. Professional/qualified systems are typically used reducing these kinds of mistakes to minimum. The professional system is a program that covers a profession which formed by selected people and it develops itself by time. Professional systems are used such situations like ranging from defining of infection to recognition of kidney disease. In this treatise, a professional system is designed which compares ratio of index finger by ring finger (2D:4D) and let us know about a person if he/she is prone to science or art. With this system, it?s purposed to help people by letting them know about their educational proclivity, by showing them the way about field selection in school-teaching process, by helping the selection in employment procedure.Key Words: Medical Informatics, The Expert System, 2D:4D Finger Length, Rate.
