Health literacy and awareness are essential strategies in promoting global health and improving access to care. While seen as an essential tool for promoting population health awareness to improve early detection and treatment of chronic diseases, it is yet to be emphasized in most African countries. Health literacy is an essential practice to promote chronic disease prevention and reduce the growing threat to population health. Incidences and mortalities from chronic diseases commonly arise from limited knowledge of the causative risk factors and access to health facilities. Without knowledge about causes, health impacts, and available health services, people continue to indulge in the habits that worsen their health conditions and fail to access care timely. By using health literacy and awareness as a tool for chronic disease prevention, healthcare professionals will develop strategic health awareness programs that fit the socio-demographics of the population they serve. This article explored the significant role health awareness occupies in individual and community health prevention through health promotion and education. It reviewed the concept and dimensions of chronic disease prevention, cultural beliefs and impact on chronic diseases, gaps created by low health literacy, and the significance of health literacy in disease prevention and health promotion. Furthermore, it recommends that health systems and local communities form partnerships to address common and emerging health problems, and health systems should be properly funded.

This paper presents a simplified graphical procedure for constructing, using an unmarked straightedge and a compass only, a 10˚ to 20˚ angle, which is in other words, trisecting a 30˚ or 60˚ angle. The procedure, when applied to the 30˚ and 60˚ angles that have been “proven” to be not trisectable, produced a construction having the identical angular relationship with Archimedes’ Construction, in which the required trisection angles were found to be 10.00000˚ and 20.00000˚ respectively (i.e. exactly one-third of the given angle or ∠E’MA = 1/3∠E’CG). Based on this identical angular relationship as well as the numerical results obtained, one can only conclude that the geometric requirements for arriving at an exact trisection of the 30˚ or 60˚ angle, and therefore the construction of a 10˚ or 20˚ angle, have been met, notwithstanding the theoretical proofs of Wantzel, Dudley, and others. Thus, the solution to the age-old trisection problem, with respect to these two angles, has been accomplished.

The Sloane Digital Sky Survey (SDSS) has been in the process of creating a 3D digital map of the Universe, since 2000AD. However, it has not been able to map that portion of the sky which is occluded by the dust gas and stars of our own Milkyway Galaxy. This research builds on work from a previous paper that sought to impute this missing galactic information using Inpainting, polar transforms and Linear Regression ANNs. In that paper, the author only attempted to impute the data in the Northern hemisphere using the ANN model, which subsequently confirmed the existence of the Great Attractor and the homogeneity of the Universe. In this paper, the author has imputed the Southern Hemisphere and discovered a region that is mostly devoid of stars. Since this area appears to be the counterpart to the Great Attractor, the author refers to it as the Great Repeller and postulates that it is an area of physical repulsion, inline with the work of Gerdpommerenke and others. Finally, the paper investigates large scale structures in the imputed galaxies.
