Objectives. The aim of this study was to review the bone density assessment techniques and evaluate the macroscopic structure of bone specimens scored by Hounsfield Units (HUs) and decide if they are always in congruence.Methods. The mandible of a formalin-fixed human cadaver was scanned by dental volumetric tomography (DVT) for planning of the specimen positions and fabrication of a surgical guide and a surgical stent was fabricated afterwards. Bone cylinders of 3.5 mm diameter and 5 mm length, were excised from the mandible using the surgical stent with a slow speed trephine drill. After removal of the cylinders two more scans were performed and the images of the first scan were used for the determination of the HU values. The removed bone cylinder was inspected macroscopically as well by micro-CT scan.Results. The highest HU values were recorded in the interforaminal region, especially in the midline (408–742). Posterior regions showed lower HU values, especially the first molar regions (22–61 for the right; 14–66 for the left first molar regions).Conclusion. Within the limitations of this pilot study, it can be concluded that HU values alone could be a misleading diagnostic tool for the determination of bone density.

Peri-implant bone density plays an important role in the osseointegration of dental implants. The aim of the study was to evaluate via micro-CT, in Hounsfield units, the bone density around dental implants coated with chitosan and melatonin and to compare it with the bone density around implants with a conventional etched surface after 12 weeks of immediate post-extraction placement in the jaws of Beagle dogs. Six dogs were used, and 48 implants were randomly placed: three groups—melatonin, chitosan, and control. Seven 10 mm × 10 mm regions of interest were defined in each implant (2 in the crestal zone, 4 in the medial zone, and 1 in the apical zone). A total of 336 sites were studied with the AMIDE tool, using the Norton and Gamble classification to assess bone density. The effect on bone density of surface coating variables (chitosan, melatonin, and control) at the crestal, medial, and apical sites and the implant positions (P2, P3, P4, and M1) was analyzed at bivariate and multivariate levels (linear regression). Adjusted effects on bone density did not indicate statistical significance for surface coatings (p = 0.653) but did for different levels of ROIs (p < 0.001) and for positions of the implants (p = 0.032). Micro-CT, with appropriate software, proved to be a powerful tool for measuring osseointegration.

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.

Abstract New Caledonia is a colonial territory of France. Since the adoption of the Nouméa Accord in 1998, a period of transition towards the exercise of self-determination has been going on. New Caledonia is currently a strong autonomy, well entrenched in the legal order of France from 1999 on. The legislative powers have been distributed between the Congress of New Caledonia and the Parliament of France on the basis of a double enumeration of legislative powers, an arrangement that has given New Caledonia control over many material fields of self-determination. At the same time as this autonomy has been well embedded in the constitutional fabric of France. The Nouméa Accord was constitutionalized in the provisions of the Constitution of France and also in an Institutional Act. This normative framework created a multi-layered electorate that has presented several challenges to the autonomy arrangement and the procedure of self-determination, but the European Court of Human Rights and the UN Human Rights Committee have resolved the issues regarding the right to vote in manners that take into account the local circumstances and the fact that the aim of the legislation is to facilitate the self-determination of the colonized people, the indigenous Kanak people. The self-determination process consists potentially of a series of referendums, the first of which was held in 2018 and the second one in 2020. In both referendums, those entitled to vote returned a No-vote to the question of ‘Do you want New Caledonia to attain full sovereignty and become independent?’ A third referendum is to be expected before October 2022, and if that one also results in a no to independence, a further process of negotiations starts, with the potential of a fourth referendum that will decide the mode of self-determination New Caledonia will opt for, independence or autonomy.
