Finding anatomical variability of organs, structures and their parts at all the stages of human development is rather topical. Determination of organometric parameters of the hard palate in fetuses and newborns is an essential part for perinatal diagnostics and understanding real parameters of the norm and pathology. Purpose of the study is to find organometric parameters of the palatine maxillary process and horizontal lamina of the palatine bone during fetal and early neonatal periods of human ontogenesis. By means of adequate anatomical methods of examination the study was conducted on 53 specimens of dead fetuses from 4 to 10 months of fetal development (from 165.0 mm to 500.0 mm of the parietal-calcaneal length (PCL)) and 9 specimens of dead neonates. The length of the palatine maxillary process during the perinatal period was found to be characterized by the two periods of accelerated development (5-7 and 8-10 months), and the period of relatively slow development (7-8 months). Its width was found to be characterized by the two period of accelerated development (5-7 and 9-10 months), and relatively slow development (7-8 months). The length of the horizontal lamina of the palatine bone is characterized by the period of accelerated development from 8 to 10 months, and the period of relatively slow development from 7 to 8 months. Meanwhile 5-8 and 9-10 months were the periods of accelerated development for its width, and 8-9 months – the period of relatively slow development for it. During fetal and early neonatal periods of human ontogenesis the value of all the paired correlation coefficients between organometric parameters of the palatine maxillary process (hard palate) and horizontal lamina of the palatine bone are positive and rather close to 1 (>0.84), which is indicative of a close positive correlation between all the organometric parameters. Very strong relation is found between the length of the hard palate and its width in the right and left (r=0.92), between the length of the hard palate and palatine bone (r=0.97), between the length of the palatine bone and the width of the hard palate in the right (r=0.91) and in the left (r=0.90). Therefore, by means of adequate anatomical methods of examination new scientifically substantiated data are obtained concerning organometric characteristics of anatomical structures of the hard palate at all the stages of perinatal period.

Selective single data on the organometric parameters of the palm in the perinatal period of ontogenesis determines the relevance of the study. The purpose of the study is to establish the organometric parameters of the palm during the fetal and early neonatal periods of human ontogenesis. The study of the palm was performed on 51 preparations of fetal corpses (from 4 to 10 months) and 10 newborns using adequate anatomical methods: macropreparation, radiography, topographic and anatomical sections, morphometry, statistical analysis. It was found that the right hand in the perinatal period of ontogenesis is characterized by its elbow shape (54 %), for the left hand – radial (71 %). The parameters of the length of the right palm are greater than the parameters of the length of the left palm in the second trimester of fetal development and in the neonatal period; in the third trimester of fetal development the length of the left palm is greater than the length of the right. The parameters of the width of the right palm exceed these parameters of the left palm during the entire perinatal period of ontogenesis. During the perinatal period of ontogenesis the organometric parameters of the palm are characterized by two periods of accelerated development and a period of relatively slow development. For the length and width of the right and left palms, periods of accelerated development from the 4th to the 5th month of fetal development and from the 7th month to the neonatal period; from the 5th to the 7th month of fetal development – a period of relatively slow development. Models for predicting the normative values of organometric parameters of the palm during the perinatal period of ontogenesis are: palm length = β0 + 0.042 x crown-heel length of the fetus, where β0: 3.587, if the age period = 4 months; 5.562 = 5 months; 4.071 = 6 months; 4.840 = 7 months; 6.881 = 8 months; 5.624 = 9 months; 5.448 = 10 months; 5.765 = newborns; palm width = β0 + 0.038 x crown-heel length of the fetus, where β0: 2.887, if age period = 4 months; 4.341 = 5 months; 2.638 = 6 months; 3.324 = 7 months; 3.548 = 8 months; 1.714 = 9 months; 1.814 = 10 months; 3.231 = newborns.

A comprehensive study of anatomical-functional peculiarities of the cranial bones promotes implementation of new methods of performing radical and reconstructive-restorative surgery on the face and cranium. Objective: to determine peculiarities of formation of the hard palate folds structure in the fetal and early neonatal periods of human ontogenesis. Materials and methods. The study was conducted on 53 specimens of dead fetuses from 4 to 10 months of development and on 9 specimens of dead neonates by means of macro- and micro-section, preparing histological and topographic-anatomical sections, and morphometry. Formation of the hard palate folds during the second and third trimesters of the intrauterine development was found to consist of the following stages:  epithelial thickening, penetration into the adjacent mesenchyme originating the rudiment of the fold; smoothing of the basal membrane and epithelial outgrowth over the surface with formation of the primary fold; condensation of mesenchyme cells under the fold apex; formation of fibrous stroma inside of the fold which is a peculiar core; epithelial smoothing to even thickness similar to that one embracing the areas between folds with formation of the final fold. At the end of the third trimester of the intrauterine development posterior transverse palatine folds become less marked, some of them disappear, and the anterior ones become more marked, closer and pressed one to another.

Formation of the structure and topography of the coronary arteries during the fetal and early neonatal periods of human ontogenesis is an essential constituent while making perinatal diagnosis and understanding real parameters of the norm and pathology. Objective of the study is to determine organometric parameters of the carotid arteries during the fetal and early neonatal periods of human ontogenesis. The study was conducted on 50 specimens of dead fetuses (from 4 to 10 months) and 9 neonates (5 isolated complexes of organs in particular) by means of adequate anatomical methods: macrodissection, injection of the blood vessels, making topographic-anatomical sections, morphometry, and statistical analysis. During perinatal period external diameters and lengths of the carotid arteries are found to be characterized by two periods of an accelerated development and the period of relatively slow development. For the external diameter of the right common carotid artery and the external diameter of the left internal carotid artery the periods from the 4th to 7th months of the intrauterine development and the period from the 9th month to the neonatal period are the periods of an accelerated development; the periods from the 7th to 9th months of development are the period of relatively slow development. The periods from the 4th to the 7th months of the intrauterine development and the period from the 10th month till neonatal period are the periods of an accelerated development for the external diameter of the left common carotid artery and external diameter of the right internal carotid artery; the period from the 7th to the 10th months of development is the period of relatively slow development. The periods from the 4th to the 7th months of the intrauterine development and from the 8th month of development till the neonatal period are the periods of an accelerated development for the external diameter of the right and left external carotid arteries; the period during 7-8th months is the period of relatively slow development. The length of the cervical part of the right and left carotid arteries is characterized by the two periods of an accelerated development – from the 4th to the 6th month and from the 7th month till the neonatal period; the period of relatively slow development is from the 6th to the 7th month of the intrauterine development.  Comparison of the developmental periods of the carotid arteries with all the possible organometric parameters enables to affirm that practically similar enlargement of the external diameters of the common, external and internal carotid arteries both from the right and left sides is peculiar for the period of relatively slow development. The first period of an accelerated development of the carotid arteries is more specific for the external diameter and length of the left common and left external artery contrary to the second accelerated period of development of the carotid arteries. It is characterized by enlargement of the external diameters of the right common and right external carotid artery. A reliable difference of the mean values of the external diameters of the right and left common, external and internal carotid arteries is peculiar for the 4th, 7th, 10th months of development and for the neonatal period for the common carotid arteries; for the external carotid arteries – the 4th, 7th, 9th months of development and neonatal period; for the internal carotid arteries – for the whole months of development.

In the study, the peculiarities of development in the embryonic and early pre-production periods of human ontogenesis are studied. The timing of the laying of structures from which gradually formed the atrium and ventricles of the heart, the interdermal and interventricular septum of the organ are established. The process of the formation of the valves of the heart has been observed. It was noted that in the prenatal of the 7th week of intrauterine development the structure of the heart resembles a definitive form. During the 4th week of intrauterine development on the upper wall the only atrium in the median line there is a concavity on the lower surface of which there is a crescentic protrusion, this is the initial of the primary atrial septum. In the 5 weeks of embryo, the free edge of the primary primitive partition grows caudally in the direction of the atrioventricular tubule, thus gradually separating the right and left atrium. In embryos 7-8 weeks of intrauterine development (embryos 18.0 - 30.0mm PСL), the heart takes the position from horizontal to vertical, due to intense and uneven growth adjacent organs and structures, especially the liver. In embrions of this age group, the length of the heart ranges from 1.5±0.05mm to 2.1±0.05mm, and the width at the base of the heart is – 480.0±10.0μm 590.0±5,0μm The thickness of the wall of the left ventricle is dominated by the thickness of the wall of the right ventricle at 30,0±2,0μm, and the thickness of the walls of the right and left atrium is almost the same.

Choice of profession is a social phenomenon that every person has to face in life. Numerous studies convince us that not only the well-being of a person depends on the chosen work, but also his attitude to himself and life in general, therefore, the right and timely professional choice is very important. Research about factors of career self-determination of students of higher education institutions in Ukraine shows that self-determination is an important factor in the socialization of young person, and the factors that determine students' career choices become an actual problem of nowadays. The present study involved full-time and part-time students of Institute of Philology and Mass Communications of Open International University of Human Development "Ukraine" in order to examine the factors of career self-determination of students of higher education institutions (N=189). Diagnostic factors of career self-determination of students studying in the third and fourth year were carried out using the author's questionnaire. Processing of obtained data was carried out using the Excel 2010 program; factorial and comparative analysis were applied. Results of the study showed that initial stage of career self-determination falls down on the third and fourth studying year at the university, when an image of future career and career orientations begin to form. At the same time, the content of career self-determination in this period is contradictory and uncertain, therefore, the implementation of pedagogical support of this process among students is effective.

ABSTRAKPutusan Nomor 2-3/PUU-V/2007 selain menjadi dasar konstitusionalitas pidana mati, juga memberikan jalan tengah (moderasi) terhadap perdebatan antara kelompok yang ingin mempertahankan (retensionis) dan yang ingin menghapus (abolisionis) pidana mati. Permasalahan dalam penelitian ini adalah bagaimana kebijakan moderasi pidana mati dalam putusan a quo dikaitkan dengan teori pemidanaan dan hak asasi manusia dan bagaimana kebijakan moderasi pidana mati dalam RKUHP tahun 2015 dikaitkan dengan putusan a quo. Penelitian ini merupakan penelitian doktrinal, dengan menggunakan bahan hukum primer dan sekunder, berupa peraturan perundang-undangan, literatur, dan hasil-hasil penelitian yang relevan dengan objek penelitian. Penelitian menyimpulkan, pertama, putusan a quo yang memuat kebijakan moderasi pidana mati telah sesuai dengan teori pemidanaan khususnya teori integratif dan teori hak asasi manusia di Indonesia di mana hak hidup tetap dibatasi oleh kewajiban asasi yang diatur dengan undang-undang. Kedua, model kebijakan moderasi pidana mati dalam RKUHP tahun 2015 beberapa di antaranya telah mengakomodasi amanat putusan a quo, seperti penentuan pidana mati di luar pidana pokok, penundaan pidana mati, kemungkinan pengubahan pidana mati menjadi pidana seumur hidup atau penjara paling lama 20 tahun. Selain itu masih menimbulkan persoalan berkaitan dengan lembaga yang memberikan pengubahan pidana mati, persoalan grasi, lamanya penundaan pelaksanaan pidana mati, dan jenis pidana apa saja yang dapat diancamkan pidana mati.Kata kunci: kebijakan, KUHP, moderasi, pidana mati. ABSTRACTConstitutional Court’s Decision Number 2-3/PUU-V/2007, in addition to being the basis of the constitutionality of capital punishment, also provides a moderate way of arguing between retentionist groups and those wishing to abolish the death penalty (abolitionist). The problem in this research is how the moderation policy of capital punishment in aquo decision is associated with the theory of punishment and human rights and how the moderation policy of capital punishment in the draft Criminal Code of 2015 (RKUHP) is related with the a quo decision. This study is doctrinal, using primary and secondary legal materials, in the form of legislation, literature and research results that are relevant to the object of analysis. This study concludes, firstly, the aquo decision containing the moderation policy of capital punishment has been in accordance with the theory of punishment, specificallyy the integrative theory and the theory of human rights in Indonesia, in which the right to life remains limited by the fundamental obligations set forth in the law. Secondly, some of the modes of moderation model of capital punishment in RKUHP of 2015 have accommodated the mandate of aquo decision, such as the determination of capital punishment outside the main punishment, postponement of capital punishment, the possibility of converting capital punishment to life imprisonment or imprisonment of 20 years. In addition, it still raises issues regarding the institutions that provide for conversion of capital punishment, pardon matters, length of delay in the execution of capital punishment, and any types of crime punishable by capital punishment. Keywords: policy, criminal code, moderation, capital punishment.

Introduction. Proper nutrition is crucial for child and adolescent athletes to maintain growth and development and to achieveoptimal results in sports. It is very important to balance the energy expenditure with the energy intake in order to prevent the energy deficit or excess.Materials and methods. Subjects involved in two different sports participated in the study: 13 gymnasts (age 13.8 ± 4.1 years, height 153.4 ± 11.3 cm, weight 47.1 ± 10.5 kg) and 15 basketball players (age 15.5 ± 1.1 years, height 176.7 ± 7.9 cm, weight 65.2 ± 10.7 kg). Determination of total energy expenditure was made by prediction equations. The subjects maintained a food records for 5 consecutive days, which were processed in the ASA24 system of the NCI. Results and discussion. Energy intake in both groups is sufficient to meet the daily needs, development of young athletes andprovide the energy needed in training. The intake of three minerals (calcium, magnesium and potassium) and three vitamins (D, E and A) was lower than recommended values in both groups.Conclusion. As a result of the busy schedule of adolescent athletes, their main meals are out of home, and the proportion of highly processed foods containing small amounts of important vitamins and minerals is high. The main recommendations include dairy products, fruits, vegetables and whole grains. The idea behind the changes is to give young athletes the right diet and the right eating habits.
