The main objective of educational institutions is to provide high quality of education. Providing a high quality of education depends on predicting the unmotivated students before they entering in to final examination. In this paper, we compare the Bayesian network classifiers for predicting the student's academic performance and generates a Model. This model helps earlier in identifying the drop outs and students who need special attention and allow the teacher to provide appropriate counselling / Advising. In Addition to this, Accurately predicting student performance is useful in many different contexts. For example, identifying exceptional students for scholarships is an essential part of the admissions process and identifying weak students who are likely to fail is also important for allocating limited tutoring resources.
INTRODUCTIONA ventral hernia is defined as a fascial defect located in the abdominal wall. Primary ventral hernias have been classified as umbilical, epigastric, Spighelian and lumber hernias, and secondary ventral hernias are incisional hernias that have developed from previous postoperative scars. 1 Ventral hernia repair is a common surgical procedure. Mostly, ventral hernias are small umbilical and epigastric hernias, but almost 30% of these procedures are incisional hernia repair is and around half of these have been done laparoscopically.
2Once the patient develops ventral hernia, it inevitably increases in size with time and surgery becomes more and more difficult and hence the repair should not be delayed. With the increase in the number of abdominal surgeries and the use of various incisions associated with surgeries, there is an increase in the incidence of incisional hernia. The surgeons became aware that certain incisions were followed by increased incidence of incisional hernia, because of this awareness, consideration was given to the choice of incision, suture materials that are being used, type of wound closure etc.., Moreover ventral hernias can become irreducible, obstructed, strangulated due top various reasons which markedly increases the risk to patient's life. The treatment of ventral hernia has evolved over many decades. Primary suture repairs were done in the beginning which carried an unacceptably high recurrence Conclusions: Laparoscopic repair of ventral hernia is showing promising results and is being widely practiced nowadays. Postoperative pain is less, hospital stay is shorter and there is a lower short term complication when compared to open repairs. There is lesser incidence of wound infection; movement of bowel is sooner, shorter hospital stay and faster resumption of routine activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
