ASSESSMENT OF PERSONAL PROPORTIONS OF SCHOOL-AGE CHILDREN TASHKENT CITY IN RELATION TO THE «GOLDEN SECTION»

Abstract

In recent decades, work has been carried out in various fields of science, in which the question of the «golden cross-section,» which is one of the geometric principles of proportional harmony, is considered. «Golden section» is such a proportional harmonic division of a segment into unequal parts, in which the entire segment (AC) relates to the larger part (AB) as the larger part (AB) relates to the smaller part (BC) or, conversely, the smaller segment (BC) relates to the larger (AB) as the larger (AB) relates to the entire segment (AC), i.e., AC/AB = AB/BC = 1.618 or BC/AB = AB/AC = 1.618. Arithmetically, the proportion of the «golden cross-section» is expressed as 1:1.618 and the value of the «golden cross-section» is conventionally denoted by the letter φ [6, 8]. According to a number of authors, the face plays an important role in people's social life and is the object of research not only for artists, anthropologists, ethnologists, educators, and psychologists, but also for medical professionals, as proportions and symmetry play a role in harmonizing not only the human body but also the size and shape of the face [2, 5, 9]. Considering facial proportions is of great importance in the practice of every doctor and, especially, a dentist, as one of the main reasons for seeking a dentist is the desire to improve the aesthetics of teeth and face [1, 2, 3, 4, 7, 10]. A.I. Postolaki's (2015) scientific article is devoted to reviewing 35 literary sources on this topic and is aimed at broader coverage and disclosure of basic aesthetic concepts to achieve the most objective assessment of facial harmony and smile; this article indicates that in recent years, there has been a special need for methods for analyzing facial structure that allow not only to study the position and size of teeth and jaw bones but also to assess facial harmony
