For more than 50 years, the continuous photographic observations of asteroids have been carried outwith telescopes of the Astronomical Observatory of the Taras Shevchenko National University of Kyiv and the Main Astronomical Observatory of the National Academy of Sciences of Ukraine. About 3,000 photographic plates were obtained, some of which were exposed in 1908. We collected the data on more than 5,500 positions and magnitudes of asteroids on these astroplates taking into account all results of the processing of observations available in various publications and in the Minor Planet Center database. All positional data were compared with JPL ephemeris and analyzed. From different series of asteroid observations the values of positional accuracy were obtained, depending on the methods of measuring and processing the plates and reference catalogs of stars. In order to systematically improve the obtained asteroid positions, we evaluated the possibilities of reprocessing some of the earliest asteroid observations applying the modern star high accuracy catalogs. Using the Tycho-2, Gaia DR2, and Gaia EDR3 as the reference catalogs, the 590 astroplates exposed on the MAO NASU Double Long-Focus Astrograph (DLA) in 1952-1986 were reprocessed based on old plate measurements. All newly determined and previous original asteroid positions were compared with the JPL ephemeris. The comparison results show an improvement in the systematic and random components of the accuracy of coordinates for new positions of asteroids. When comparing the new positions of the asteroids  determined in the Tycho-2 and Gaia catalog systems, no significant changes in accuracy were found.

The collections of Cryptophagidae beetles stored in the natural museums of Ukraine were studied: three academic and two university collections – State Museum of Natural History, National Museum of Natural History and I.I. Schmalhausen Institute of Zoology of the National Academy of Sciences of Ukraine, Zoological Museum of T. Shevchenko Kyiv National University and Museum of Natural History of V. Karazin Kharkiv National University, and also author’s work collection. The volumes and the state of their preservation have been analyzed. The representation of different species in collections, as a whole, and in relation to the Carpathian fauna is evaluated. In general, museum collections contain 1346 samples of Cryptophagids, in each of which – about 210-340 individuals, all of them are stored in separate boxes and punctured by entomologic needles. The author's collection includes 1657 specimens of 57 species, which are mostly stored on cotton mattresses. All six collections include 122 species of 16 genera, containing from 21 to 85 species of this family. Some samples in collections have been lost for various reasons, in 10 cases there are only needles with labels without the samples themselves, therefore, some species (eg Cryptophagus nitidulus, C. hexagonalis) are represented in collections conditionally, only in labels. At the revision of materials attention is paid to taxonomic changes, through which in the publications and in the actual material different species or generic synonymic names were used. The author also took into account the uniqueness of each of the collections, which was determined by several important parameters, including the number of samples that are presented exclusively in some of the museum of species and genera of the family, the number of samples and type specimens in collection. For most of these parameters the leader is the collection of Zoological Museum of T. Shevchenko Kyiv National University. All data is included in the author's database, which contains summaries of annotations containing collections of samples, names of regions and localities of collection, dates, collectors, or owners of the collection, and also notes with clarifications of places or details of reidentifications.

In the Tycho-2 catalogue system the processing of 1529 photographic plates of the FON Dushanbe project from the collection of the Institute of Astrophysics of the National Academy of Sciences of Tajikistan was completed. The photographic plates with the size of 8º×8º (30x30 cm) were exposed in the zones from -8º to + 84º in the period of 1985-1992 years. In years 2017 – 2020 the plates were digitized using a Microtek ScanMaker 1000XL Plus scanner with the resolution of 1200 dpi, so the size of the digitized images is near 13000x13000 px. Based on the results of the processing of digitized images a catalogue of equatorial coordinates α, δ and B-magnitudes of stars for the northern hemisphere of the sky was created. The catalog contains about 30 million stars and galaxies for the epoch 1988.74. The average internal accuracy of the catalogue for all objects is σαδ = ±0.32" and σB = ± 0.11 m (for stars in the range of B = 8 m -14 m the errors are σαδ = ±0.19" and σB =±0.07 m ) for equatorial coordinates and B-magnitudes respectively. The convergence between calculated and reference positions from the Tycho-2 catalogue is σαδ = ±0.07" and the convergence with photoelectric B-magnitudes is σB = ±0.16 m . Five astronomical institutions took part in the processing of the photographic plates and in the creating of the FON-Dushanbe catalogue: Institute of Astrophysics of NAS of Tajikistan; Walter Hohmann Observatory, Essen, Germany; Ulugh Beg Astronomical Institute UAS, Uzbekistan; Research Institute “Mykolaiv Astronomical Observatory”, Ukraine and Main Astronomical Observatory NASU, Ukraine.

Analysis was performed on the basis of research carried out in cooperation with the I. Krypiakevych Institute of Ukrainian Studies of National Academy of Sciences of Ukraine and Uzhhorod National University. During the archaeological excavations conducted in 2018–2019 on the territory of Uzhhorod Castle, the remains of burials within the ruins of the church were studied. It is noted that plundered remains were destroyed in the crypts and beyond their borders. Among the fragmentarily preserved funeral equipment were found personal items of Christian worship, which lay mostly in a redeposited state. It is determined that the artifacts represent several categories: scattered rosary beads, crosses and medallions. The article is devoted to the characteristics of six medallions. The main attention is focused on the iconography of images, deciphering inscriptions and clarifying the content and ideological value of plots. In the process of characterizing the images on the medallions, individual figures were identified, placed in pairs – Saints Sebastian and Roch, Paul the Hermit and Anthony of Egypt. It was found that a fragment of one medallion is dedicated to Saints Benedict and Zechariah, whose figures are missing, but their images symbolize the texts of the prayers they concluded. It has been established that two medallions on the obverse and reverse contain images of Jesus Christ and Mary, respectively. The features of the compositions presented on the medallions are identified with the corresponding plots related to the lives of the saints. The features of the compositions presented on the medallions are identified with the corresponding plots related to the lives of the saints. It is stated that the content of these stories reflects certain aspects of Christian ideology, which professed various spiritual communities. It is noted that the analysis of technical and technological features of medallions producing made it possible to link their production with professional Western European workshops and to date within the XVII – first quarter of the XVIII century. On the other hand, on the basis of a broad characterization of the content of iconography, connection with monastic orders, process of the formation of the cult of these saints, the emergence of their reliquaries in Europe, endowing the saints with certain guardian properties are revealed. Anti-epidemic significance of the cult of saints is noted. At the same time, it is stated that the considered medallions represent reflection of religious and funeral culture in the aristocratic environment of early modern Hungary. Key words: monastic orders, burials, medallions, iconography, Christian symbols, anti-epidemic guardians.
