The Relationship

Expanding the theoretical knowledge of medical anthropology in the modern field of dental services is one of the main drivers of progress in the orthodontic field. The only way to successfully develop the relationship of these disciplines is to create and fill a database of normative data and search for correlations between various, both obviously related and, at first glance, completely unrelated structures of the human body. The purpose of the study was to determine the features of the relationship between the linear dimensions of molars with the cephalometric parameters of practically healthy men of the first mature age, residents of the western region of Ukraine. Cone-beam computed tomography was performed in 36 practically healthy men of the first mature age, residents of the western region of Ukraine (from Rivne, Volyn, Chernivtsi, Lviv, Ternopil, Khmelnytsky, Ivano-Frankivsk and Zakarpattia regions) followed by odontometry research and cephalometry. Statistical processing of the results was performed in the license package “Statistica 6.1” using non-parametric Spearman’s statistics. As a result of quantitative analysis of reliable and average strength of unreliable correlations of linear computed tomographic sizes of molars with cephalometric indicators and indices of practically healthy men of the western region of Ukraine it is established that the percentage, mainly direct, reliable and average strength of unreliable correlations of linear sizes of molars with cephalometric indices and with indicators of the cerebral or facial skull is almost no different. The largest number of reliable and medium-strength unreliable correlations of linear molars sizes with cranial indices was found with vestibular-lingual and mesio-distal tooth sizes (20.5% with upper molars and 25.0% with lower molars). The highest number of reliable and medium-strength unreliable correlations of linear molars sizes with facial skull indices was found for upper molars with tooth height, crowns and root length (10.8%) and vestibular-lingual and mesio-distal dimensions (12.8%), and for lower molars – only with vestibular-lingual and mesio-distal dimensions (19.4%). The obtained data testify to the prospects of the chosen scientific direction of research, which will further improve the work of physicians in various fields of medicine, including preventive.

In the late 1950s, the National Archives of Ghana (NAG) began a decentralizaton programme which has progressed to the point where there is now a NAG regional depository in eight of the country's nine regions, the only exception so far being the Upper Region. Furthermore, unlike many of the efforts at bureaucratic decentralization in Ghana, which have been more de jure than de facto -- archival decentralization in Ghana is a reality. As a result, the historical researcher who limits his efforts to the Accra branch of the NAG is risking the loss of considerable richness of detail, as a recent trip to Sekondi made abundantly clear to me.Sekondi houses the Western Regional Branch of the NAG. The Western Region is, in many respects, one of Ghana's most interesting areas. Until relatively recently it was, at one and the same time, the major center of foreign business activity in the country, and one of the country's most backward and underdeveloped areas. While ironic, this juxtaposition is certainly not surprising. But more importantly, from the point of view of the researcher into Ghana's history, it affords the opportunity for a more detailed micro-level historical examination of, for instance, the relationship between “modernity” and “tradition,” or between the “capitalist mode of production” and the “pre-capitalist mode of production.” The Western Region has been almost an ideal type in this respect, and as a consequence is virtually a laboratory, not only for the historian, but also for the historically-minded sociologist, economist, and political scientist.

The Relationship

The question of the relationship between the metric characteristics of cranial structures and odontometric parameters, and the possibility of building models based on them, which can later find their practical application in dental practice, remain a pressing problem of modern medical science. The purpose of the study is to establish the features of the relationship between the linear dimensions of molars with the cephalometric parameters of the brain and facial skull of practically healthy men in the northern region of Ukraine. 32 practically healthy residents of the northern region of Ukraine (from Kyiv, Zhytomyr, Sumy and Chernihiv regions) underwent computed tomography followed by odontometry of molars and cephalometry. The correlations between odontometric and cephalometric parameters were assessed using Spearman’s nonparametric statistics in the licensed package “Statistica 6.1”. The peculiarities of the correlations of the studied characteristics of molars with the indicators of the cerebral skull are established – multiple, only direct reliable (r = 0.35-0.57) and unreliable (r = 0.30-0.35) average correlation force (18.7% on the upper jaw, of which the relative majority with vestibular-lingual and mesio-distal dimensions and 24.1% on the lower jaw, of which the relative majority with the height of the teeth, their crowns and the length of the tooth roots); as well as with the indicators of the facial skull – mostly direct reliable (r = 0.35-0.51) and unreliable medium strength (r = 0.30-0.37) correlations, in most cases of a single nature (6.0% on the upper jaw and 6.6% on the lower jaw, almost uniformly with the height of the teeth, their crowns, root length, vestibular-lingual and mesio-distal dimensions). The results of correlation analysis of craniofacial structures are necessary for the correct construction of mathematical models, which can later find their practical application in dental practice and forensic medicine.

Stroke is a loss of brain function caused by the cessation of blood supply in part of the brain. Death of brain tissue due to stroke can cause muscle weakness in the affected limb such as fingers. This condition affects the ability to move and the quality of life of patients. Patients not only experience paralysis but also experience cognitive impairment, communication disorders, and visual field disorders or deficits in perception. Aims this study was to describe handgrip strength The average age of respondents was 60.5 years with the youngest age 41 years and 80 years of age. The average strength of the handgrip is 7.4 kg with the lowest strength is 1.3 kg and the highest is 18.6 kg. Obtained a relationship between age and muscle strength after stroke (p 0.023). The relationship between age and post-stroke muscle strength shows that the relationship between medium strength and negative patterning means that as you age, muscle strength decreases. So it is necessary to develop the Pattern of Activities and exercises for Post Stroke in Hospitals and the Community.

The high prevalence of pathologies of the dental and tooth-jaw system both in Ukraine and abroad requires scientists to search for new, fundamental discoveries, in particular, to identify patterns of the relationship between cephalometric and odontometric indicators within certain ethnic populations. The purpose of the study is to establish the features of the correlations of computed tomography sizes of molars with cephalometric parameters of practically healthy men in the southern region of Ukraine. 33 practically healthy men of the first mature age, inhabitants of the southern region of Ukraine (from Mykolayiv, Kherson, Odesa, Zaporizhia regions and the Autonomous Republic of Crimea) underwent cephalometry and cone-beam computed tomography followed by odontometry of molars. The correlations between odonto- and cephalometric parameters were assessed in the license package “Statistica 6.1” using non-parametric Spearman statistics. In almost healthy men of the southern region of Ukraine in the qualitative analysis of multiple nature, mostly direct reliable and medium unreliable correlations, found only between most sizes of molars on the lower jaw and the length and height of the nose. Quantitative analysis revealed the most significant correlations between computed tomography sizes of molars and face sizes (7.4 % on the upper jaw, most of which are inverse, and 13.2 % on the lower jaw, almost evenly straight and inverse). With the indicators of the skull, the relative majority of reliable, mostly inverse correlations are observed with the height of the teeth, their crowns and the length of the roots (on the upper jaw 11.4 %, on the lower jaw 5.4 %); and with indicators of the facial skull – almost evenly with the height of the teeth, their crowns and the length of the roots (on the upper jaw 6.4 %, on the lower jaw 14.6 %, in both cases mostly reverse) and with vestibular-lingual and mesio-distal dimensions (on the upper jaw 8.7 %, mostly reverse, on the lower jaw 11.8 %, mostly straight). The obtained results of correlation analysis of computed tomography sizes of molars with cephalometric indicators and indices confirm the population specificity of the features of the dental system and are necessary for the correct construction of regression models.

According to the data of modern scientific literature in order to achieve goodfunctional and aesthetic indicators, prevention of the development of relapse in theprocess of orthodontic treatment should take into account the interdependenceodometometric and cephalometric indicators. In this case, orthodontists need to makean amendment to the features of correlations characteristic of one or another ethnicgroup of the population. The purpose of this study was to establish the features of theconnections of linear computational-tomographic sizes of premolars and their roots withcephalometric indices of practically healthy men of the Western and Eastern regions ofUkraine. On the basis of the medical center "Vinintermed LTD", 71 healthy and healthymen aged from 19 to 35 years from the Western region (n = 36, residents from Volyn,Rivne, Lviv, Chernivtsi, Ternopil, Khmelnytsky, Transcarpathian and Ivano-Frankivskregions) and the Eastern region (n = 35, residents from Kharkiv, Donetsk and Luhanskregions), a cone-ray computer tomography was performed using the Veraviewepocs-3D dental cavity beam (Morita, Japan). On cone-ray computer tomograms small angularteeth of the upper and lower jaws were measured: the length of the tooth; the lengthof palatal and cheek's roots of small angular teeth of the upper and lower jaw; heightof tooth crown; vestibular-lingual dimensions of the crown and neck of the tooth;mesio-distal dimensions of the crown and neck of the tooth. Cephalometric studieswere conducted taking into account the generally accepted recommendations andanatomical points. The statistical processing of the obtained results was carried outusing the statistical software package "Statistica 6.1" using the nonparametric Spirmanmethod. A number of anthropogenetic studies confirmed the division of Ukrainians intoregional groups (East, West, North, South), divergence between them reaches a highlevel. Therefore, the difference between the correlations of odonto-kefalometricindices between regions with a larger taxonomic distance (east-west, north-south)should be expected. As a result of the conducted researches in practically healthymen the following regional features of connections of linear sizes of premolars withcephalometric indicators of a brain skull are established: the Western region is mainlydirect reliable (r = 0.34 - 0.45) and unreliable average force (r = 0.30 - 0.36) connections(9.0% on the upper jaw, of which the relative majority are with the height of teeth andtheir crowns and the length of the roots and 7.6% on the lower jaw, of which the relativemajority is mesio-distal and vestibular-lingual sizes); the Eastern region - mostly reversereliable (r = -0.34 - 0.45) and unreliable mean strength (r = -0.30 - 0.34) connections(5.1% on the upper jaw and 5.4% on the lower jaw, in both cases the relative majoritywith the height of the teeth and their crowns and the length of the roots). The followingregional peculiarities of connections were established with the indicators of the facialskull: the Western region - mostly direct (r = 0.33 - 0.57) and unreliable meanstrength (r = 0.30 - 0.42) connections (9.9% on the upper jaw and 12.2% on the lowerjaw, in both cases the relative majority of mesio-distal and horse-lingual dimensions);Eastern region - mostly direct (r = 0.34 - 0.52) and unreliable mean strength (r = 0.30 - 0.44) connections (7.4% on the upper jaw, of which the relative majority with heightteeth and their crowns and the length of the roots and 9.2% on the lower jaw, of whichthe relative majority are mesio-distal and vestibular-lingual dimensions).Keywords: regional features, premolars, cephalometry, correlations, practically healthymen

The Relationship

This paper presents an interactive study on the relationship between the foreign trade structure, opening degree and economic growth of the provinces in western China (except Tibet). It shows that the export of primary products and labor-intensive products has a positive impact on the external development of the western region, while the export of capital and technology-intensive products has a smaller inhibitory effect on it. At the same time, the system GMM model shows that the opening degree of the western region has a positive effect on economic growth. After including the foreign trade structure interaction item, this result has not changed, and on the basis of opening up to the outside world, the export of labor-intensive products and capital-intensive products plays a significant role in promoting economic development. Therefore, this paper holds that the western region should optimize its foreign trade structure, continue to promote the construction of foreign trade demonstration, and give priority to the development of local characteristic industries to promote economic growth.
