3-TIER E-COMP: A NOVEL E-COMMERCE MANAGEMENT PORTAL BASED ON SECURED SDLC APPROACH

In today’s business world, there is an urgent need to develop a new approach for customer to business owner transactionssecurely. This research develops, implements, and discussed a novel 3 – Tier E-Commerce Management portal. This makesonline business very flexible and secured on the part of business owners and customers. Our proposed system seeks toreplace the conventional E-commerce models on the internet today. We argue that process logic manipulation using SecuredSoftware Development Life Cycle (SSDLCM) on Ecommerce platform is a promising scheme for studying andunderstanding script processing on the new web paradigms. In this research, we define security calculus for 3 Tier EComPwith the aim of eradicating SQL injection possibilities as well as exploiting Software as a service in a dynamic Ecommercedomain. Also, we developed a new access hierarchy for E-commerce comprising of Application layer users, designatedadministrator and super administrators in the 3 – Tier EComP. We developed a new encryption scheme based on XAMPMD5 Random Curve Cryptography (XMD5 – RCC) running on Secure Socket Layer (SSL) which protects the user andadministrators on the Ecommerce platform. The result of encryption scheme randomly generates and secures the logindetails dynamically on the server during the authentication and authorization phases. The programming was accomplishedwith PhP, and MySQL Server. The overall methodology as detailed in the body of the work could serve as good template forapplication developers and other researchers.Keywords: E-Commerce, XMD5-RCC, SSL, Platform, SSDLCM, Software, Servic

Clustering Algorithm for a Healthcare Dataset Using Silhouette Score Value

<p>The huge amount of healthcare data, coupled with the need for data analysis tools has made data mining interesting research areas. Data mining tools and techniques help to discover and understand hidden patterns in a dataset which may not be possible by mainly visualization of the data. Selecting appropriate clustering method and optimal number of clusters in healthcare data can be confusing and difficult most times. Presently, a large number of clustering algorithms are available for clustering healthcare data, but it is very difficult for people with little knowledge of data mining to choose suitable clustering algorithms</p

Role of Women Organizations in Community Development: A Case Study of Orlu Agricultural Zone, Imo State

The paper analysed the role of women organizations in the development of rural communities in Orlu Agricultural zone of Imo state. Six communities were purposively selected from three Local Government Areas of the Zone for the study. Semi-structured questionnaire was used to collect data from 120 randomly selected women from the chosen communities from July to August 2005. Data analyses were achieved using simple descriptive statistics as percentages, frequency tables and ranking. Result of the study shows that women organizations/associations for the purpose of community development in the study area are formed at different levels (community, village, and kindred) and along different ties (religious, family and social). There was a remarkable high involvement rate of women organizations in the provision of infrastructural amenities as renovation/ furnishing of town halls (80%), renovation/equipment of village schools (81.7%), and churches (82.5%), and provision of communal environmental sanitation services (88.3%). Other development programmes include those aimed at economic and educational empowerment of women and community youths such as; provision of grants/loans for enterprise development of women (81.7%), award of scholarships to children of the community (77.5%), awareness creation on HIV/AIDS (94.2%), family health and child care programmes (81.7%), and other general health matters (60.0%). It was recommended among others that existing women organizations in the rural communities should be encouraged by way of adequate recognition, training and funding by the State and Local Government authorities.
