Authors: Yehia Sania Ali , Morad Wesam Saber , Hendy Olfat Mohamed , Dorgham Laila Shehata
Published: January 2020

Background

Hepatocellular carcinoma is an important public health problem worldwide and in Egypt. It has a bad prognosis and few treatment options. HCV and HBV infection and exposure to pesticides and aflatoxins are major risk factors for its development, so paying more attention to prevention via raising population awareness about its risk factors may be useful in lowering HCC incidence. This study was implemented to study knowledge, attitude, and practice (KAP) of a rural community of Menoufia governorate, Egypt, pre- and post-health education intervention about HCC and prevention of its risk factors.

Results

Seroprevalence of HCV among study participants was 12.3%, and the health education intervention about HCC and the prevention of its risk factors was effective in increasing the percent of pre-intervention good knowledge score groups about HCC, HBV, and HCV, pesticides, aflatoxins, and total knowledge score from 66.5%, 88.8%, 83.8, 41.9%, and 73.7% respectively to 98.9%, 100%, 100%, and 98.9% post-intervention (p value = 0.000 for each) and was also effective in increasing the pre-intervention positive attitude score groups from 61.5 to 98.9% post-intervention. It was also effective in increasing the pre-intervention safe practice score groups of male and female study participants from 20% and 23% respectively to 94.3% and 93.1% post-intervention.

Conclusions

Health education intervention was effective in improving KAP about HCC and prevention of its risk factors and could be adopted by MOHP as a part of comprehensive program for HCC prevention in rural communities of Menoufia governorate.

Published: January 2020

Background: Most postpartum women in low- and middle-income countries want to delay or avoid future pregnancies but are not using modern contraception. One promising strategy for increasing the use of postpartum family planning (PPFP) is integration with maternal, newborn and child health (MNCH) services. However, there is limited evidence on effective service integration strategies. We examine facilitators of and barriers to effective PPFP integration in MNCH services in Kenya and India.  

Methods: We conducted a cross-sectional, mixed-method study in two counties in Kenya and two states in India. Data collection included surveying 215 MNCH clients and surveying or interviewing 82 health care providers and managers in 15 health facilities across the four sites. We analyzed data from each country separately. First, we analyzed quantitative data to assess the extent to which PPFP was integrated within MNCH services at each facility. Then we analyzed qualitative data and synthesized findings from both data sources to identify characteristics of well and poorly integrated facilities.

Results: PPFP integration success varied by service delivery area, health facility, and country. Issues influencing the extent of integration included availability of physical space for PPFP services, health workforce composition and capacity, family planning commodities availability, duration and nature of support provided.

Conclusions: Although integration level varied between health facilities, factors enabling and hindering PPFP integration were similar in India and Kenya. Better measures are needed to verify whether services are integrated as prescribed by national policies.
A role for MIR828 in pineapple fruit development
Authors: Rock Christopher D.
Published: January 2020

Chen et al. (Nature Genet. 51: 1549–1558; Oct. 2019) sequenced Ananas comosus var. bracteatus accession CB5, cultivated for its bright pink-to-red colored fruit, and yellow-fleshed A. comosus accession F153, reporting an improved F153 reference assembly while annotating MICRORNA (MIRNA) loci and gene family expressions relevant to lignin and anthocyanin biosynthesis. An independent article (Xiong et al. Sci. Rep. 8: 1947; 2018) reported var. bracteatus MIRNAs but not MIR828, a negative regulator of anthocyanin and polyphenolics biosynthesis by targeting MYB transcription factors associated with UV light- and sugar-signaling in dicots. MIR828 has been reported in gymnosperms, Amborella (sister to flowering plants), and basal monocot orders Liliales, Asparagales, Zingiberales, Arecales, but not in the Poales, a sister order comprising grasses and ~3,000 species of bromeliads including pineapple. Here I show MIR828 exists in pineapple and directs post-transcriptional gene silencing of mRNAs encoding MYB family members with inferred function to regulate the conspicuous red fruit trait in var. bracteatus. MIR828 plesiomorphy (an ancient basal trait) may shed light on monocot apomorphic fruit development, postulated for 21 monocot families with fleshy fruits as due to homoplasy/convergence driven by tropical climate and/or enticements to vertebrate endozoic seed dispersers.

Authors: Eliakim Alon , Eliakim Michal , Pantanowitz Michal , Meckel Yoav , Nemet Dan
Published: January 2020

The present study examined whether background music improves aerobic and anaerobic performance in overweight children. Eleven participants (14.6±1.5 yrs, BMI%: 94.3±6.5) performed aerobic (20m Shuttle Run) and anaerobic (repeated sprint test – RST) field tests. Ten participants (12.0±2.1 yrs, BMI%:97.4±1.6) performed aerobic (treadmill running) and anaerobic (Wingate Anaerobic Test – WAnT) laboratory tests. Treadmill running time was significantly longer with, compared to without, music (11.9±1.5 versus 10.6±2.2 min, respectively; p<0.007). There was no significant difference in the 20m shuttle run distance with or without music. Total sprint time was significantly faster during RST with, compared to without, music (47.7±4.7 versus 48.5±5.5 s, respectively; p<0.04), with no significant difference in ideal sprint time and performance decrement. There was no significant difference in peak and mean anaerobic power and fatigue index during the WAnT with and without music. Motivational music may be used to improve aerobic and anaerobic performance among overweight children.

Rent-Oriented Behavior of Student Youth: State and Challenges
Authors: Burganov Rais
Published: January 2020

Among the current problems of Russian society are abuses in the field of public administration, caused by rent-oriented behavior of representatives of one family-related group. To start solving this sensitive problem for society, it is necessary to have baseline data, including on the views of young people on the possibility of obtaining political rent through the use of family and family ties in social development. This paper presents some of the research results on the basis of a survey of student youth. According to the author, it is necessary to thoroughly and extensively consider the regulatory provisions on the participation of family-related groups in the implementation of political rent and create a systematic scientific concept.
Basic Methodological Approaches to the Study of Personality Direction on Volunteer Activity
Authors: Ishkova E.
Published: January 2020

The volunteer sector in our country is experiencing rapid growth, while the issue of the nature and content of the personality orientation towards volunteering remains insufficiently studied. The subjective-activity approach has a sufficient methodological basis for the study of the phenomenon of “personality orientation toward volunteering”. In the framework of this approach, the following constructs are distinguished: “the orientation of the individual toward volunteer activity”, “values”, “motives”, “attitudes” and their interconnection is shown. The phenomenon of personality orientation toward volunteer activity is defined as a complex dynamic integral formation, the key characteristic of which is the value substructure. Based on the data contained in some analyzed sources, it is shown that the definition of the concept of “altruism” is synonymous with understanding the essence of “volunteering”.

Features of Perception of Own Body by Persons with Health Limitations
Authors: Morozova E. , Artemyeva Svetlana , Zhuravleva E. , Sherchenkova O.
Published: January 2020

According to the World Health Organization, about one fifth of the total number of people with disabilities are people with lesions of the musculoskeletal system, which occurred as a result of various injuries in adulthood. In their psychological essence, they are the cause of a serious and hard-lived non-regulatory crisis of personal development, which requires from her enormous internal efforts to restore optimal interaction with other people and with society as a whole. The defeat of the musculoskeletal system necessarily entails a violation of the morphological and functional characteristics of a person, which also causes a change in his perception of his body. In this regard, the basis for correcting the psychological status of persons with disabilities (HIA) should be to eliminate the distortion of ideas about their body, ensure that they take on their appearance, develop the desire to compensate for physical limitations that have arisen after injury and neutralize feelings of inferiority. Formation of a positive attitude to the perception of the personality of your body is designed to ensure a reduction in the level of depression, anxiety, feelings of hopelessness, activation of the life plans of the individual and her ability to overcome life difficulties. Achieving a state of adaptation depends on the resources of the individual himself, who has beco me disabled as a result of physical trauma and on the effectiveness of specially organized psychological influences carried out in the process of implementing trainings aimed at developing a positive attitude towards perception of one’s body. The high efficiency of the complex of trainings was shown: development training of compensatory abilities, “temporary perspective”, art therapy training.

Personal therapists' voices in the systemic first consultations. Dialogical analysis.
Authors: Bryniarska Antonina , Tomasiewicz Aleksandra , Janusz Bernadetta , Józefik Barbara
Published: January 2020

Cel pracy

Celem badania było rozpoznanie specyfiki pojawiania się osobistych wątków uruchomionych w umyśle terapeuty w trakcie prowadzenia psychoterapii i ich relacji z profesjonalnym działaniem – myśleniem terapeuty. Badanie polegało na dokonaniu nagrań, a następnie przeprowadzeniu analizy sesji terapii rodzin lub par, jak również wywiadów z terapeutami.

Metoda

Rozmowy z terapeutami zostały przeprowadzone za pomocą wywiadu przywołującego procesy mające miejsce w trakcie sesji terapeutycznej (Interpersonal Process Recall, IPR [1]). Dokonano porównania pomiędzy analizowanymi przykładami, wykorzystując studium przypadków (multiple case study). Wybrane fragmenty, w których zidentyfikowano autobiograficzne odniesienia, zostały poddane analizie dialogowej (dialogical analysis), wyodrębniając „ja doświadczające” i „ja profesjonalne” terapeuty [2] oraz zachodzące pomiędzy nimi relacje. Następnie przeanalizowano siedem wywiadów IPR z psychoterapeutami przeprowadzonych bezpośrednio po pierwszej konsultacji: czterech rodzin i trzech par, skierowanych do terapii z różnych powodów — zaburzeń odżywiania, konfliktów rodzinnych, uzależnień czy zaburzeń zachowania. Wszyscy terapeuci pracowali w nurcie systemowym, byli certyfikowanymi terapeutami i superwizorami.

Wyniki

Dokonana analiza pozwoliła zidentyfikować pięć fragmentów dotyczących osobistych skojarzeń i myśli terapeuty, które zostały przytoczone przez terapeutę w trakcie wywiadu IPR. Przeprowadzona analiza dialogowa ujawniła, że uruchomione doświadczenie autobiograficzne, głos osobisty, w każdym przypadku wywołuje w dalszej kolejności pojawienie się głosu profesjonalnego reflektującego świadomość osobistej perspektywy w trakcie konsultacji (matapozycja obserwatora własnych uczuć i myśli). W połowie przykładów świadomość ta była powiązana z analizą możliwego wpływu głosów osobistych na przebieg terapii.

Wnioski

Uruchomione wątki biograficzne w sesji terapeutycznej mogą mieć jedynie formę dostrzeżenia podobieństwa doświadczeń terapeuty i rodziny, ale także mogą wiązać się z pogłębioną refleksją dotyczącą ich znaczenia dla procesu terapeutycznego. IPR jest użytecznym narzędziem do badania zjawiska głosów osobistych..
The role of therapeutic activities in the recovery of people treated for schizophrenia spectrum disorders
Authors: Witkowska-Łuć Bogumiła
Published: January 2020

Cel pracy

Celem badań było poznanie roli aktywnego uczestnictwa w zajęciach terapeutycznych pacjentów hospitalizowanych z powodu schizofrenii w ich procesie zdrowienia. W leczeniu osób chorujących na schizofrenię standardem jest stosowanie leków przeciwpsychotycznych, ale u wielu pacjentów poprawa funkcjonowania nie jest w pełni zadowalająca. Uzasadnione staje się włączanie w proces leczenia pomocy terapeutycznej.

Metoda

Zbadano 134 pacjentów ze zdiagnozowaną schizofrenią paranoidalną lub psychozą schizoafektywną leczonych w oddziałach całodobowych. Do oceny poziomu nasilenia objawów psychopatologicznych posłużyła Skala Objawów Pozytywnych i Negatywnych (PANSS) S.R. Kaya, L.A. Oplera, A.Fiszbeina oraz ankieta własnego autorstwa, umożliwiająca określenie stopnia zaangażowania pacjenta w zajęcia terapeutyczne. Z badanej grupy, w oparciu o kryteria autorskie, wyodrębniono dwie podgrupy: z pozytywnym oraz negatywnym efektem zdrowienia. Porównywano dwie grupy różniące się poziomem poprawy objawowej.

Wyniki

Udział oraz aktywność pacjentów w zajęciach terapeutycznych (terapia zajęciowa, psychoedukacja, psychorysunek, muzykoterapia, psychoterapia grupowa, psychoterapia indywidualna, klub pacjenta) w grupie z pozytywnym efektem zdrowienia była istotnie wyższa niż wśród pacjentów z negatywnym efektem.

Wnioski

Aktywne i systematyczne uczestniczenie w zajęciach terapeutycznych okazało się istotnie wspomagać proces zdrowienia pacjentów z zaburzeniami z kręgu schizofrenii.

Relics of the Polish Language of the North-Eastern Borderland in the Former Boundaries of Polish-Lithuanian Commonwealth (Southern Lands of the Pskov Province). Part IThe present paper consists of two parts, and presents the spoken Polish of the North-Eastern Borderland, as well as borrowings from Polish which function in the dialects of the Pskov province. Three regions with different histories have been included. The southern lands of the Pskov province (the area which belonged to the Polish-Lithuanian Commonwealth until 1772) were described in the first part of the article. The sociolinguistic situation and loanwords borrowed from Polish (or via Polish) were analysed basing on two sources: the author’s materials collected during dialectological field research, and material from The Pskov Regional Dictionary with Historical Data. The Pytalovo region (which belonged to Latvia in the interwar period) and the historical Pskov region (where there were no Polish settlements) were described in the second part of the paper. Two sources were used: The Pskov Regional Dictionary with Historical Data, and The Dialectological Dictionary of One Family (Pytalovo Region of the Pskov Province).

Lemko Etymologies. Part IIIThe present paper is the third part in the Lemko etymologies series; analysed in it are words beginning with letters Ж–З: жбыр, жґыртати, жґрынджати, жджар, жджок, жоґати, жомба, жуграти, забіль, зайда, заниско (занізка), збаршніти (зборшніти), збрескнути, згацькати, згырити ся, згужвати (зужвати), згусувати ся, зґырцати, здабати, зипы, зрешіти, зуноватися, зьдіватися. Authors attempt to establish the origin of those words, taking into account data from etymological, historical, and dialectal dictionaries of Slavic languages and dialects, as well as from the neighbouring non-Slavic languages, thereby outlining a broad comparative background. They propose additions and corrections to previous etymological findings regarding some of the discussed words.
Kazimierz Nitsch jako historyk języka
Authors: Dunaj Bogusław
Published: January 2020

Kazimierz Nitsch as a Historian of LanguageKazimierz Nitsch is the founder of Polish dialectology. In addition, he also studied, though to a lesser extend, contemporary Polish language and its history. His early works in the field of linguistic history are typical philological studies. An analysis of rhymes in poetry from the 16th to the beginning of the 20th century was methodologically innovative, and allowed for an interpretation of some phonetic processes that took place in the past. Growing out of dialectological research, the most important method applied to the interpretation of historical linguistic processes, was reasoning about their course on the basis of an analysis of the reaches of certain phenomena in dialects. The great merit of K. Nitsch was the initiation in 1913 of a discussion about the origin of the Polish literary language.
Wielojęzyczność indywidualna jako problem badawczy lingwistyki. Przypadek Bronisława Malinowskiego
Authors: Mazur Anna
Published: January 2020

Individual Multilinguality as a Research Problem in Linguistics. The Case of Bronisław MalinowskiThe goal of the paper is to outline the methodological approach to a study of a multilingual person, and their linguistic output recorded in multilingual texts. It employs the set of conceptual and research instruments developed for the investigation of individual bilingualism and recorded bilingual speech, and uses them to explore the linguistic strategies of Bronisław Malinowski, an outstanding anthropologist and a multilingual person who consciously exploited the codes he knew in the process of creating multilingual texts – heterogeneous by their very nature, and yet cohesive. A multilingual text is a text in which several languages coexist, but always only two codes meet in a given point on the line of the text. Traces of the meeting of languages are visible in the form of transcodic markers. Their formal and functional analysis serves to examine the rules on which several languages have been introduced into a text, which can be an inspiration to outline the grammar of individual multilinguality.
Hipoteza Witolda Mańczaka o ugrofińskim substracie w językach bałtyckich
Authors: Witczak Krzysztof Tomasz
Published: January 2020

Witold Mańczak’s Hypothesis about the Finno-Ugric Substrate in the Baltic Languages

The paper discusses Witold Mańczak’s hypothesis concerning a Finnic (particularly Balto-Finnic) substrate in the Baltic languages (Mańczak 1990: 29–38; 1993: 151; 2008: 149–152), as well as J. H. Holst’s critical evaluation of the problem (Holst 2015: 151–173). Mańczak lists as many as ten arguments in support of the substrate theory: According to Meillet (1925: 100–101), the disappearance of the neuter gender in Lithuanian and Latvian occurred under the influence of Balto-Finnic languages, since the category of gender is absent from Finno-Ugric; Old Lithuanian displays secondary local cases (i.e. illative, allative, adessive, ines-sive), formed using postpositions according to the Finno-Ugric pattern (Meillet 1925: 101); The Lithuanian constructions expressing evidentiality (e.g. Lith. nešęs velnias ak-menį) – as well as their Latvian counterparts – appeared due to substrate influence, according to Pisani (1959: 217); The Lithuanian numerals 11–19 ending in -lika (e.g, Lith. vienúolika ‘eleven’, dvýlika ‘twelve’, etc.) are of substrate origin (Pisani 1959: 217); The particle of the Lithuanian imperative -ki or -k (e.g. OLith. dúoki ‘give’) – repro-duces a similar particle known from Finnish, according to some scholars (Топоров, Трубачев 1962: 249–250); The alternation of voiced and voiceless consonants like blekai / plekai ‘tripe’ (Kiparsky 1968: 76–90 lists 200 such doublets in Latvian and 50 in Lithuanian) may be caused by the influence of a Finno-Ugric substratum, since the Finno-Ugric lan-guages used to lack voiced consonants; There are Common Baltic terms of Finno-Ugric origin, e.g. the name for ‘amber’: OPrus. gentars, Lith. giñtaras, Latv. dzĩtars m. ‘amber’ (Bednarczuk 1976: 47–48). The use of the genitive instead of an adjective in East Baltic (e.g. Lith. lietuvių kalba ‘Lithuanian language’, Latv. latviešu valoda ‘Latvian language’), unknown in other Indo-European languages, arose through Balto-Finnic influence – cf. Finnish suomen kieli ‘Finnish language’, Est. eesti keel ‘Estonian language’ (Bednarczuk 1968). The territory of Latvia abounds in hydronyms of Finnic provenance, while in Lithuania we may identify the name Nemunas (chief river in the area) as well as ca. 30 other river names of potential Finno-Ugric origin (Zinkevičius 1984: 155). The non-distinction of grammatical number in third-person finite verb forms in Lithua-nian, Latvian and Old Prussian was, according to some researchers (e.g. Thomason, Kaufman 1988: 243), caused by Balto-Finnic influence. Besides, the present author reviews Holst’s critical paper on the theory of a Uralic substratum in Common Baltic.
A czy to ja kalika, czy nie mom konika? (Nie)sprawność w świetle erotyku ludowego
Authors: Niebrzegowska-Bartmińska Stanisława
Published: January 2020

A czy to ja kalika, czy nie mam konika? (lit. ‘Am I a Cripple, or Don’t I Have a Horse?’). Disability in the Light of Folk Erotic Poetry

Folk erotic poetry, as ‘a song of lovers not yet tied by the knot’, is a genre of text that relates the notion of love and the image of intimate body parts, the roles assigned to woman and to man, as well as social and moral norms in the traditional community. At the base of this genre lie such values as: happiness in love, physical contact, lovers’ openness to the love game, youth and beauty, success and favour, the light-heartedness of the lovers, fun and laughter, freedom, faithfulness and stability; marriage is a relative value, important for the girl, and wealth. Another value that is important in the light of folk erotic poetry, is an able body, sexual performance; the anti-value is a body that is diabled, sick, deprived of its functionality. Deficiency in the art of love, the man’s incompetence or inability to perform a sexual act is for the poetic lover a kind of disability that devalues and disqualifies him as a man and the partner of love act in the eyes of a woman awaiting sexual fulfillment. From the point of view of the heroine, it is justified to describe such a lover (love-cripple) as a disabled or even defunct person. The reason for this unambiguous and stigmatizing categorization is not only the inability to provide the girl (also a young wife by an old man) with erotic pleasure (kochanie ‘touching, moving’), but also to perform the love act which the folk culture understands as a participation in the creative action of the entire cosmos.
Adjacency radiance around a small island: implications for system vicarious calibrations
Authors: Bulgarelli Barbara , Zibordi Giuseppe
Published: January 2020

The adjacency radiance field surrounding a small island (i.e., the Lampedusa Island in the Central Mediterranean Sea) was theoretically analyzed to address implications on a hypothetical nearby system vicarious calibration (SVC) infrastructure for satellite ocean color sensors. Simulations, performed in the visible and near-infrared regions for the Ocean Land Color Instrument (OLCI) operated onboard Sentinel-3 satellites, show different patterns of adjacency effects (AE) around the island. In the direction of the reflected sunbeam (i.e., in the north-western region), AE mainly originate by missing glint contributions from the sea surface masked by the island. These AE are mainly negative, decrease with wavelength, and strongly depend on sea surface anisotropy (i.e., sea state) and illumination conditions; this hinders the capability to provide a general unique description of their features. In the remaining marine regions, AE are positive and do not exceed the radiometric sensitivity of OLCI data beyond approximately 14 km from the coast. At shorter distances, uncertainties in satellite radiance due to AE would hence not allow fulfilling requirements for SVC.
Simplified unobscured optics design for a diffractive telescope
Authors: He Chuanwang , Huang Peng , He Yiwei , Dong Xiaochun , Fan Bin
Published: January 2020

An unobscured optical system provides a good solution for a high-performance diffractive telescope. However, the unobscured diffractive telescope, such as an off-axis three-mirror diffractive telescope (OTDT), suffers from the complex calculation of initial parameters, strict tolerance, and fabrication of aspheric mirror diffractive optical elements (DOE). In this paper, a simplified unobscured design method, which is effective in achieving compact and loose tolerance, is proposed. Combining the deflection of an optical path and Schupmann achromatic theory, a novel unobscured diffractive telescope is rapidly converted from a coaxial transmissive system. Not only is the loose tolerance obtained, but the fabrication of an aspheric mirror DOE is avoided. The designed system, with a focal length of 400 mm,

Raster adaptive optics for video rate aberration correction and large FOV multiphoton imaging
Authors: Li Yongxiao , Lim Yean J. , Xu Qiongkai , Beattie Lynette , Gardiner Elizabeth E. , Gaus Katharina , Heath William R. , Lee Woei Ming
Published: January 2020

Removal of complex aberrations at millisecond time scales over millimeters in distance in multiphoton laser scanning microscopy limits the total spatiotemporal imaging throughput for deep tissue imaging. Using a single low resolution deformable mirror and time multiplexing (TM) adaptive optics, we demonstrate video rate aberration correction (5 ms update rate for a single wavefront mask) for a complex heterogeneous distribution of refractive index differences through a depth of up to 1.1 mm and an extended imaging FOV of up to 0.8 mm, with up to 167% recovery of fluorescence intensity 335 µm from the center of the FOV. The proposed approach, termed raster adaptive optics (RAO), integrates image-based aberration retrieval and video rate removal of arbitrarily defined regions of dominant, spatially varied wavefronts. The extended FOV was achieved by demonstrating rapid recovery of up to 50 distinct wavefront masks at 500 ms update rates that increased imaging throughput by 2.3-fold. Because RAO only requires a single deformable mirror with image-based aberration retrieval, it can be directly implemented on a standard laser scanning multiphoton microscope.

Lasing was obtained with output couplers having transmissions in the range of 1–3%, and as high as 124 mW of continuous-wave (cw) output power was generated with 604 mW of absorbed pump power by using the 3% output coupler. Broadly tunable cw lasing could be obtained in the 2268–2373 nm wavelength range. An analysis of the experimental power efficiency data shows that nearly all of the absorbed pump photons were converted to 2.3 µm laser output after accounting for the quantum defect of the laser transition and resonator losses. We expect that higher lasing efficiency should be possible by using longer crystals to increase the pump absorption.

Intensity noise cross-correlation of the polarization eigenstates of light emerging from an atomic vapor cell in the Hanle EIT configuration results in high resolution spectroscopy even with free-running semiconductor lasers. We show that the character of the observed intensity noise in any output polarization basis can be modeled as a Markov process in the input light fields’ amplitudes that excite the response of a three-level medium. This method has promise as an inexpensive and simpler approach to vector magnetometry and has applications in timekeeping and as a probe of dynamics of atomic coherence in warm vapor cells.

O estabelecimento do paradigma do membro articulado no De motu animalium de Aristóteles
Authors: Oliveira Eraci Gonçalves de
Published: January 2020

No De motu animalium, Aristóteles recorre ao método analógico na pesquisa que faz acerca da causa comum do movimento, estabelecendo o paradigma do membro articulado, modelo que ele operacionaliza tendo em vista tornar inteligível o caráter dinâmico do movimento dos animais. Contudo, o membro articulado não se apresenta como modelo de uma maneira direta, na verdade, ele é convertido em modelo. Textualmente, o estabelecimento do paradigma, ou modelização, começa em 698a17 e vai até 698b4, incluindo três etapas: a primeira referência às articulações; a geometrização do movimento do membro articulado, que compreende três subdivisões: a comparação da articulação com o centro, a geometrização radical que é a comparação com o diâmetro, e a relativização da comparação geométrica; e por último, a volta à natureza da articulação com o modelo anatômico do membro articulado, o ponto culminante do processo de modelização. No artigo presente, gostaríamos de fazer uma análise das etapas da construção deste paradigma, cujas estratégias metodológicas culminam no modelo anatômico do membro articulado, uma surpreendente imagem em ação para o objeto do De motu, que, paradoxalmente, dá a ver a imobilidade na mobilidade do membro.
Chondroplasty Efficacy of Bone Matrix
Authors: Yu.M Iryanov , N.A Kiryanov
Published: January 2020

Aim
To study the chondroplasty efficacy of the bone matrix obtained using an original technology in restoring cartilage defect of the knee joint.

Material and Methods
Marginal defects were modeled on the surface of the distal end of the femur in 40 adult male Wistar rats. The bone matrix obtained using an original technology was implanted in the damaged area in animals of the experimental group. Material was investigated by means of light microscopy, transmission and scanning electron microscopy, and electron probe X-ray microanalysis.

Results
It was found that the bone matrix implanted did not cause an immune rejection reaction, activated reparative chondrogenesis for a prolonged period. In the area of articular cartilage lesion, the regenerate acquiring cellular and histochemical characteristics of the hyaline cartilage tissue was formed. The chondroinductive properties for the bone matrix were ensured by localized growth factors and morphogenetic proteins released during osteoclastic resorption.

Conclusion
The application of the bone matrix as a stimulator of chondrogenesis is theoretically reasonable and has a good perspective in treatment of damages and diseases of the articular cartilage.

Os resíduos de serviços de saúde (RSS) causam impacto à saúde pública e ao meio ambiente quando gerenciados de maneira inadequada. A falta de conhecimento sobre os riscos desses resíduos pelos profissionais da área da saúde e pela população acarretam na destinação incorreta dos mesmos, os quais acabam sendo encaminhados para o programa de coleta seletiva e, posteriormente, às cooperativas de materiais recicláveis. Diante disso, o estudo objetivou analisar as rotas percorridas pelo caminhão da coleta seletiva do Município de Pelotas/RS nas zonas de abrangência do programa e identificar os tipos de fontes geradoras de RSS que se encontram nessas rotas. Por tratar-se de uma pesquisa exploratória, utilizaram-se as ferramentas do Sistema de Informação Geográfica (SIG), que permitem a realização de análises espaciais e geração de informações através de mapas. Foi possível identificar em uma zona 99 estabelecimentos de saúde e, na outra, 15, sendo que esses reúnem tanto atendimento à saúde humana quanto à saúde animal. A presença de RSS em meio a resíduos recicláveis evidencia a necessidade de maiores ações educativas e fiscalizatórias, sendo que, para este último, o SIG pode ser utilizado como uma ferramenta auxiliar.

Caravaggios Medusenschild von 1597 – ein Gorgoneion?
Authors: Hager Constanze
Published: January 2020

Caravaggio’s emblematic Medusa is mostly regarded as a representation of the mirrored decapitation of the Gorgon and thus as a reflection on Perseus’ protective shield. This essay proposes a new interpretation: Caravaggio’s Medusa is an adaptation of the antique Gorgoneion. The Gorgoneion historically depicted Medusa’s head with its petrifying gaze, which was placed on the shield of Athena. Due to its symbolic and protective power, the Gorgoneion became a frequent subject in art and handicraft well into Baroque art. Caravaggio’s contemporaries – including the poets Gaspare Murtola and Giambattista Marino – left witness that they interpreted the image as a Gorgoneion. In addition, the image itself contains elements that buttress this interpretation, including, inter alia, the green surface of the shield and the shadow. Both the historic accounts and the painted details therefore render an interpretation of the painting as Gorgoneion very likely.
Joseph christophore dans la Fuite en Egypte: transmission d’un schéma iconographique spécifique à travers le Moyen Age
Authors: Aliferis Laurence Terrier
Published: January 2020

In the vast majority of representations of the Flight into Egypt, the child is huddled upon the Virgin’s lap or held in her arms. In addition to this traditional model, some interpretations of the Flight into Egypt show the child riding on Joseph’s shoulders or being held in his arms. The inventory of the representation of Joseph christophore from the fifth century to the mid-fifteenth century in Latin and Greek Christendom provides an insight into the frequency of this iconographic specificity of the Flight into Egypt, its diffusion and regional adaptations, as well as its meanings, via theological and exegetical texts.
The Creation of the World by Virgil Solis
Authors: Chernetsky Irina
Published: January 2020

Virgil Solis (1514 – 1562), a prosperous artist and printmaker from Nuremberg, dedicated his final major work to an illustration of Ovid’s Metamorphoses. Although the designs of most of the woodcuts for this first extensive German series were borrowed from the Metamorphoses series of the French artist Bernard Salomon (c. 1508 – 1561), a closer study reveals several notable differences in the details of individual scenes, among them The Creation of the World. Placing Solis’ work within the tradition of the printed illustrated editions of Ovid’s magnum opus, which had by then crystallized mainly in Italy and France, the article argues that Solis’ illustration drew not only on the earlier Metamorphoses, but also on printed German Bibles, following the parallels taken up at the time between the Creation story in the Metamorphoses and the Creation story in Genesis.
Art Is Still Not Enough. Bilder von AIDS im Spannungsfeld zwischen Kunstanspruch und politischer Mobilisierung
Authors: Junge Sophie
Published: January 2020

The paper examines the reception of HIV/AIDS-related artworks from the 1980s by comparing four New York exhibitions from the early 1990s and 2010s. It argues that to this day artworks dealing with AIDS are bound to political and moral demands of former activists from the AIDS movement in New York. This politicization of historical images of AIDS is striking since the disease has lost its fatal threat in Western countries and political constellations have changed. Yet current exhibitions focus only on activist, politically motivated responses to the epidemic in order to represent an “appropriate” remembrance of AIDS. Thirty years after the climax of the epidemic, images of AIDS are currently integrated in the canon of art history, while they are continuously claiming their political efficacy.
The Danish Fate of Two German Collections Pieces of the Baron von Häckel and C. L. von Hagedorn Collections Rediscovered
Authors: Svenningsen Jesper
Published: January 2020

The article aims to cast new light on two important collections of paintings in eighteenth-century Germany and how they ended up (complete or in part) in Danish ownership. The fate of the Hagedorn collection is well studied, yet extremely few pieces of the collection have so far been identified in modern collections. Two such paintings – both of them among Hagedorn’s favorite pictures – are published here. The 1763 sale of the collection formed by Baron von Häckel is equally well known, though it has escaped everyone’s attention that a further 75 paintings were separated from the rest and presented to the Danish king. About half of these pictures can still be found in the Statens Museum for Kunst in Copenhagen.
