DESIGN AND IMPLEMENTATION OF AN EXPERT SYSTEM ON MEDICAL DIAGNOSES AND PRESCRIPTION
(CASE STUDY OF STOMACH ALCER)
 ABSTRACT
          As the need of system almost every activity man can perform increase, software for the admission of students into polytechnics should not be left out. This software can process the credentials of 1000 credentials in about 20 minutes higher one computer operator if provided with the required data and this would have taken about 4 people 12 hours to do.
          This project was borne out of the necessite to address the inherent problem encountered by staff of the admission department and students of Akanu Ibiam Federal Polytechnic Uwana, Afikpo.
          The manual processes involved in the admission of students were critically examined and the flows noted. The software often to a great extent, the solutions to these problems. The project went further to treat the different techniques used in implementing the new software in order to facilitate a broader understanding of the designed software by any user.
          The project also presents in a concise, yet through form, the various mechanics included in locating and addressing the issue of time wastage in the admissions of student. If offers the prospective user a sense of achievement.

INTRODUCTION
 1.1     THE BACKGROUND OF THE STUDY
          Expert system play an indomitable role in various disciplines and the assistance it renders to man cannot be overemphasized. This chapter marks the beginning of the design of an expert system on medical diagnosis and prescriptions. For a smooth take off, the statement of the problem, purpose of study, aims and objective, scope of study, limitation, assumption, definition of terms are treated which are pre-requisites for the design.
          These key points are extensively treated in the proceeding chapters to justify the claims.  
 1.2     STATEMENT OF THE PROBLEM
          Expert system can be defined as a sophisicated software, which aids some expert and professional in various disciplines to carry out some vital functions. The use of expert system can be broadly applied in medical diagnosis and prescriptions oil prospecting and chemistry on the artificial intelligence. This is an act of subjecting a computer system to take some intelligent decisions based strictly on the problems at stake.
          The use of expert system on medical diagnosis and prescriptions include the interest of the research because of some spectacular activities it accomplished and to bring the awareness of the software to the doorstep of the readers and other medical and paramedical personnel’s.
          The software helps the junior doctors accompanied by a nurse in answering the calls of some patients with tedious problems. This also helps the doctors generating some wise questions from a patient, based on the problems confronting him in order to get rid of some outstanding irregularities. Some potentialities built-in, which serves as a watch, dog patients on the sick beds. It helps in alerting a medical practitioner on call of imminent dangers against a patient and alleviates nurses the task of engaging themselves routine visits.
 1.3             PURPOSE OF STUDY
          One of the major hindrances is that militate the sob of medical doctors is the problem of decision taking. This is sometimes brought about by mobility to generate some wise questions, which will form a locus study in taking a lasting decision. This may at the long run become detrimental to the patient concerned henceforth calling for a sorry situation.
 1.4     AIMS AND OBJECTIVE
          In order to give an orientation to the case under study, the researcher has decided to present the following Aims and Objective.
(1)     Expert system helps a medical doctor in decision-making strategies.
(2)     Judicious medical prescriptions are facilitated by an expert system.
(3)     Expert system plays an unover emphasizing role in assisting the paramedical personnel’s in acting like qualified medical doctors.
 1.5     SCOPE OF STUDY
            Anybody can act like a professional in an discipline whether affiliated to him or not if he has all the necessary tenets to act. A paramedical staff can behave like a medical doctor If he has. Within his jurisdiction some aiding equipment. This can be so helpful in the absence of a qualified medical doctor to salvage lives.
