Introduction. The actual problem of dentists-orthopedists at the present time is a violation of the odontopreparation protocol and, as a result, poor-quality fixation of various non-removable orthopedic structures. For a strong and reliable fixation of non-removable orthopedic structures, special requirements must be imposed on them in terms of the shape and surface of the support of the processed tooth. These requirements include: parallelism of the walls of the prepared tooth (must be cylindrical); parallelism of the vertical walls of the stumps of the teeth, high-quality gingival ledge [1], [2]. Qualitatively prepared teeth for orthopedic structures, observance of parallelism of the walls create optimal conditions for stable fixation of orthopedic structures. Correctly executed gingival ledge promotes durable fixation of the crown and eliminates the likelihood of infection under it. After analyzing a large volume of domestic and foreign literature, it can be concluded that the creation of various methods of odontopreparation with the task of creating the most favorable supragingival part of the tooth for further fixation of the orthopedic structure is a significant problem in modern dentistry. The creation and clinical testing of DNT (dental navigation technologies) allows for accurate quality control of the performed odontopreparation. The purpose of this article was to analyze the existing methods of odontopreparation and identify the most effective ones among them.

This paper describes the development of a systematic approach to the creation, management and curation of linguistic resources, particularly spoken language corpora. It also presents first steps towards a framework for continuous quality control to be used within external research projects by non-technical users, and discuss various domain and discipline specific problems and individual solutions. The creation of spoken language corpora is not only a time-consuming and costly process, but the created resources often represent intangible cultural heritage, containing recordings of, for example, extinct languages or historical events. Since high quality resources are needed to enable re-use in as many future contexts as possible, researchers need to be provided with the necessary means for quality control. We believe that this includes methods and tools adapted to Humanities researchers as non-technical users, and that these methods and tools need to be developed to support existing tasks and goals of research projects.

Indonesian quality of legislation is far from perfect which indicated by the high number of judicial review. Using juridical normativemethods, this study examines the causesof poor quality of legislation and the adequacy of theLaw on the Establishment of Legislation to produce high quality legislation. The study found that, first, the poor quality of the legislation occurred due to the lack of elements of transparency and accountability in the formation of legislation. Second, the Lawon the Establishment of Legislationisincompetence for the creation of good quality legislationdue to unstructured of public participationmechanism andinscrutable process of decision-making. Kualitas peraturan perundang-undangan Indonesia masih jauh dari sempurna yang diindikasikan dengan tingginya angka pengujian undang-undang. Dengan menggunakan metode yuridis normatif, studi ini mencari penyebab rendahnya kualitas peraturan perundang-undangan dan kemampuan Undang-Undang tentang Pembentukan Peraturan Perundang-undangan untuk menghasilkan peraturan perundang-undangan yang berkualitas. Studi ini menemukan bahwa, pertama, rendahnya kualitas peraturan perundang-undangan disebabkan belum dipenuhinya unsur transparansi dan akuntabilitas dalam pembentukan peraturan perundang-undangan. Kedua, Undang-Undang tentang Pembentukan Peraturan Perundang-undangan masih belum mampu menghasilkan peraturan perundang-undangan yang berkualitas karena tidak terstrukturnya pengaturan mengenai partisipasi publik dan tidak dapat ditelusurinya proses pengambilan keputusan.


In construction production, the safety of constructing buildings and structures is achieved by ensuring the required quality as a result of systematic construction control based on the implementation of a complex of technical, economic and organizational measures at all stages of the object's life cycle. The article deals with the actual problem of improving the quality of construction products-buildings and structures in conjunction with the activities of construction control bodies. The article presents the advanced foreign and domestic experience of ensuring the quality control at the construction sites, providing for the prevention of the underlying causes of defects and increasing the interest of the contractors directly. On the basis of the analysis of the current situation with quality control at the construction market, ways to improve its efficiency by developing a unified system of technological implementation of relevant requirements for the quality of construction products, determining the rational number and business load of construction control engineers, as well as the active activities of self-regulatory organizations in this area are offered.

The experience of clinical testing of the personal telemedicine system ‘Obereg’ for remote monitoring of patients at the intensive care units of leading Russian clinics is described. The high quality of communication with the remote receiving devices of doctors, the accuracy of measurements, resistance to interference from various hospital equipment and the absence of its own impact on such equipment were confirmed. There are significant advantages compared to stationary patient monitors, in particular, for intra and out-of-hospital transportation of patients.

ABSTRACTRevolutionary struggle in order to compete for the independence of Indonesia has been a source of inspiration Indonesian artists, including Bambang Soelarto who wrote drama Domba-domba Re- volusi (DDR). DDR studied drama is quite interesting because it tries to criticize the freedom fight- ers. This study aims to: first to know the theme and the problem plays DDR; second to determine the relationship of the socio - historical struggle in 1948 with the sociological elements of drama DDR themes and issues. This study uses sociological theory of art. The basic principles of the sociology of art is the fact that the creation of works of art influenced by the historical social conditions where the work was created. Research using content analysis of Krippendorf, the methods used to examine the symbolic phenomena with the aim to explore and express the observed phenomenon which is the content, meaning, and an essential element of the literary work. Based results of this research is that Bambang Soelarto as the author tries to capture di?erence between fighters during the struggle for the political aspirations for 1948 are expressed in a work of drama. Historical events inspired the creation of drama DDR. Soelarto want to respond to the political aspirations of the di?erence between historical figures and wanted to provide an assessment and outlook through DDR.Keywords: themes, drama, sociology of art, social historical ABSTRAKRevolusi perjuangan dalam rangka memperebutkan kemerdekaan Indonesia telah men- jadi sumber inspirasi para seniman Indonesia, termasuk Bambang Soelarto yang menulis drama Domba-domba Revolusi (DDR). Drama DDR cukup menarik diteliti karena mencoba mengkritisi para pejuang kemerdekaan. Penelitian ini bertujuan untuk: pertama, mengeta- hui tema dan permasalah drama DDR; kedua, mengetahui hubungan kondisi sosio-histo- ris perjuangan pada tahun 1948 dengan unsur-unsur sosiologis terimplisir pada unsur tema dan masalah drama DDR. Penelitian ini menggunakan teori sosiologi seni. Prinsip dasar dari sosiologi seni adalah adanya fakta bahwa penciptaan karya seni dipengaruhi oleh kon- disi sosial historis tempat karya itu diciptakan. Penelitian ini menggunakan metode con- tent analysis dari Krippendorf, yakni metode yang dipergunakan untuk meneliti fenome- na-fenomena simbolik dengan tujuan untuk menggali dan mengungkapkan fenomena yang teramati yang merupakan isi, makna, dan unsur esensial karya sastra. Berdasarkan hasil penelitian dapat diketahui bahwa Bambang Soelarto sebagai penulis mencoba un- tuk menangkap perbedaan antara pejuang aspirasi politik selama perjuangan tahun 1948 untuk diekspresikan dalam sebuah karya drama. Peristiwa sejarah mengilhami penciptaan drama DDR. Soelarto ingin menanggapi aspirasi politik perbedaan antara tokoh-tokoh se- jarah dan ingin memberikan penilaian dan pandangan pandangannnya melalui DDR.Kata kunci: tema, drama, sosiologi seni, sosial historis

A number of modifications to traditional techniques are suggested in order to overcome problems that frequently arise when growing crystals from solution. These improvements, and their combination, help to avoid problems such as poor nucleation, the spontaneous precipitation of many poor-quality small powder-like crystals, crystals adhering to the crystallization vessel or to each other, and chemical degradation of the solution. The proposed techniques can be used to crystallize desirable metastable polymorphs reliably. None of the suggested methods demands the usage of any special or expensive equipment, or specific skills, and they can be implemented in the chemistry curriculum even at secondary school level. Examples are given for the crystallization of small organic molecules such as carboxylic acids, amino acids, pharmaceuticals etc., but the same techniques are applicable to other classes of compound.
