The study that is related to the biological, physiological and social aspects is referred to as Gerontology. There are so many diseases that affect the elderly every year. Many of them are unrecognizable. So to study those diseases and to make a solution for that disease gerontology has been introduced. The multidisciplinary nature of gerontology means that there are a number of subfields, and associated fields such as psychology and sociology that overlap with gerontology. Gerontologists view aging in terms of four distinct processes: chronological aging, biological aging, psychological aging, and social aging.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
