Abstract: Malaria is a serious public health problem in the tropics. This study, investigated the mosquito repellent effect of the plant Azadirachta indica extracts of the seed kernel and fruit bark on human volunteers. Two different mosquito species were used, female anopheles and culex . It was observed that the fruit bark exhibited slight repellent activity, significant at p<0.05 for the number of bites between 0-60 minutes by culex mosquitoes. The seed kernel extract exhibited significant repellent activity, significant at p<0.01 and also the extract was more effective on the female anopheles than on the culex mosquito species.

Garlic Volatile Oil as Promising Fumigan for the Cotrol of the Lesser Grain borer Rhyzopertha dominica (adult)
Mahgoub Ishag A.alla, Azhari Omar Abdel Bagi

Abstract: Laboratory experiments were carried out to investigate the efficacy of the fumigant action of garlic volatile oil on Rhyzopertha dominica (adult) in small cups (200 g) and jute sacs (100 g) to shed light on suitable fumigation period and concentration. Garlic volatile oils were tested at concentrations ranging between 0.1 and 20% v/v for short exposure (6-48 hrs) and medium exposure periods (3-15 days), however for longer exposure period (15-60 days) concentrations were between 0.001-1.0 v/v. The results of the short periods indicated that garlic volatile oils are very effective and caused significant mortalities to the test insects in cups at all concentrations tested (after waiting recoveries for seven days) compared to control. Effect was dosage related. However the insect was found to be sensitive to garlic fumigation. The test insect efficacy was tested over medium (3-15 days) and longer (15-60 days) exposure periods in sacs in the latter using much lower concentrations (0.001-1.0). The results indicated that garlic oil was able to penetrate through sacs and cause significant death to the test insect (R. dominica (adult)) compared to control. Effect was dose dependant. The performance of garlic fumigation in cups is much similar to that in sacs. Recovery cases noticed were little and negatively related to the dosage.

C.A Ior, G. Ayanbimpe, L.D. Ior, J. Okechalu, G. O.Chris-Otubor

Abstract: Cryptococcus neoformans is an opportunistic human pathogen that causes cryptococcosis, a life-threatening infection that is usually manifested as menigeoencephalitis mainly in immunocompromised patients. The objective of this study was to evaluate the presence of Cryptococcus neoformans from four environmental sources; water, soil poultry droppings and pigeon guano in Jos, plateau state, Nigeria. Two hundred samples, fifty samples each of water, soil, poultry droppings and pigeon guano were collected from five different settlements in Jos. Each sample was suspended 1:10 in saline solution and then cultured in Sabouraud's dextrose agar medium including chloramphenicol. Identification of C. neoformans was performed on the basis of melanin synthesis on bird seed agar, presence of a capsule on India ink preparation, urease production on urea agar medium, and ability to grow at 37 °C. An assimilation test was also used to confirm C. neoformans. Of the 200 samples, 17(8.5%) were positive for C. neoformans. The highest frequency was observed in pigeon guano 8(16.0%) followed by soil 6(12.0%) and poultry droppings 3(6.0%) no isolate was made from water. The study showed the presence of C. neoformans in environmental sources especially in domestic birds.

AJAYI Olusola Olajide, OGUNLEYE Olumuyowa Hezekiah, OJEYINKA Taiwo Olusegun, IYARE Rachel Nkem, LAWAL Muideen Adekunle, ISHEYEMI Olufemi Gabriel

Abstract: Automatic retirement system is a research work that provides the automation of the manual system of retirement process in an academic institution. The system will automatically trigger the retirement process once the set parameters are reached. In order to accomplish the proposed system for retirement, the following methodologies were adopted: Establishment of the theoretical foundation for the research work through considerable review of different range of works in personnel management and also developing a decision support system for the proposed system.This research work would be of great benefit to universities in the sense that the study will enable the institution to know when to recruit another set of employees once the date for older employees’ retirement and their numbers are known. Also, there is a time-based reminder that gives alerts of the employees due for retirement; consequently, the employees are served reminder memo of their retirement date.

Data Mining with Decision Tree to Evaluate the Pattern on Effectiveness of Treatment for Pulmonary Tuberculosis: A Clustering and Classification Techniques
Babu C Lakshmanan, Valarmathi Srinivasan, Chinnaiyan Ponnuraja

Abstract: Data mining is a process which helps in uncovering interesting data patterns in large volume of data. This procedure has become an ever more activity in all areas of medical science research especially in healthcare circumstances. Data mining has resulted in the innovation of useful hidden patterns from enormous databases. In this paper, a methodology is proposed for the programmed exposure and classification to evaluate the pattern on effectiveness of treatment for Pulmonary Tuberculosis (PTB) patients. Tuberculosis is a disease caused by mycobacterium which spreads through the air and hits low immune bodies easily. Our methodology is based on clustering and classification that classifies the success rate of Tuberculosis treatment based on the two broad classifications of the drug susceptibility testing (DST) namely, sensitivity to all drugs and resistance to any one drug. Age and weight are the main influencing factors for PTB patients, Two Step Clustering(TSC) is used to group data into different clusters and assign classes based on age and weight besides, The same procedure is being compared between with and without clusters of age and weight. Subsequently multiple different classification algorithms are trained on the result set to build the final classifier model based on decision tree along with K-fold cross validation method. The best obtained treatment effectiveness was 97.9% on a specified pattern from Classification and Regression Trees (CART). The proposed approach helps clinicians in their treatment planning procedures for different categories (through decision trees) to discover relationships which are currently hidden in the data.
