Published: October 2022

OBJECTIVE: The first aim of this study was to evaluate the prevalence of A. actinomycetemcomitans in a large Brazilian population. The second aim was to analyse the frequency of A. actinomycetemcomitans serotypes, P. gingivalis, P. intermedia, T. forsythia and C. rectus in the positive individuals for A. actinomycetemcomitans. MATERIAL AND METHODS: The population was composed of 1,320 individuals. Subgingival biofilm samples were taken for molecular analysis. RESULTS: It was revealed that 263 (19.9%) individuals tested positive for A. actinomycetemcomitans. Then, the genomic DNA of A. actinomycetemcomitans serotypes (a to f ) as well as P. gingivalis, P. intermedia, T. forsythia, and C. rectus were analysed. A. actinomycetemcomitans serotype a was detected in 28.5%, serotype b in 15.97%, serotype c in 51.71%, and serotype e in 3.80% of individuals, respectively. Serotypes d and f were not detected. The frequency of A. actinomycetemcomitans serotype a was significantly higher in C. rectus-positive individuals than in P. gingivalis-, P. intermedia-, or T. forsythia-positive individuals. Additionally, the frequency of serotypes b and c were significantly higher in both C. rectus- and T. forsythia-positive individuals in comparison to P. gingivalis- and P. intermedia-positive individuals. Meanwhile, the frequency of serotype e was not associated with the presence of the other periodontal pathogens. CONCLUSION: The data of this large population confirmed A. actinomycetemcomitans prevalence values previously observed in smaller groups. Further, suggested potential coaggregation among selected A. actinomycetemcomitans serotypes and other target periodontal bacterial species in the subgingival environment.

Published: October 2022

INTRODUCTION: Biological complications around dental implants, including peri-implantitis and peri-implant mucositis, result from host-modulated response to bacterial biofilm. Current treatment approaches for these conditions do not adequately decontaminate implant surfaces and instrumentation is likely to damage the implant surfaces. OBJECTIVE: The aim of this study was to evaluate the bactericidal effect of laser diode irradiation (GaAlAs 810 nm) on biofilms formed in vivo on titanium surfaces, and to determine optimal laser parameters for disinfection. Ten participants wore an intraoral appliance each containing six titanium discs (Ra = 0.5) for 96 hours to generate multispecies biofilms. Discs were irradiated (ex vivo) with a range of diode laser outputs. Discs were stained with fluorescent viability dyes and examined by confocal laser-scanning microscopy and by scanning electron microscopy. After 96 hours, biofilms containing various bacterial morphotypes covered the entire disc surfaces. RESULTS: Diode laser irradiation resulted in a dose-dependent bactericidal effect with maximal antimicrobial efficacy at = 75 J/cm2. At this setting, no viable bacteria were evident, however cellular remnants and intracellular matrix were apparent. No damage to the titanium surface was evident following exposure to = 150 J/cm2. CONCLUSION: Diode laser irradiation effectively kills natural biofilms without damage to the titanium surface but the consequences of non-viable biofilm remnants on tissue healing remains to be determined.

Published: October 2022

INTRODUCTION: People with halitosis suffer various consequences, incurring social, professional, and affective limitations that impair their confidence, spontaneity, and self-esteem. However, the existing treatment protocols focus on treating halitosis alone, rather than its psychological consequences. OBJECTIVE: The objective of this study is to present a new protocol for treating the consequences of halitosis, as well as investigating its clinical application. METHODS: After briefly reviewing existing halitosis classifications and their limitations, this paper presents new classifications and techniques appropriate for the present protocol, such as the use of in vivo exposure, adequate to halitosis treatment. A total of 156 people complaining of halitosis were selected. The participants breath was evaluated using the organoleptic test and Halimeter®. The psychological consequences of halitosis were assessed using the Halitosis Consequences Inventory (ICH). The symptoms of Social Anxiety Disorder (SAD) were measured using the Social Phobia Inventory (SPIN) and its short version (Mini-SPIN). RESULTS: The results showed that all participants had tongue coating or tongue biofilm. Of the 156 volunteers, 74.38% had halitosis (n=116), of whom 100% had oral halitosis, and 3.21% had oral halitosis simultaneous with extraoral halitosis (n=5). A comparison between the pre- and post-treatment results indicated that the protocol was effective to treat bad breath as well as the feeling of insecurity, since significantly decreased the psychological consequences of halitosis and SAD symptoms; 62.6% of participants reported a significant improvement in their confidence and spontaneity at the end of treatment. CONCLUSION: Taken together, these findings were most effective for those who followed the treatment guidelines strictly.

Published: October 2022

INTRODUCTION: Since subjects affected by periodontitis might present an enhanced expression of the vascular endothelium growth factor (VEGF) gene, the aim of this study was to evaluate if polymorphic variants of the VEGF 936C/T gene polymorphism were associated with the periodontitis. MATERIALS AND METHODS: Oral mucosa cells were collected from 43 individuals diagnosed with periodontitis stages III and IV, and from periodontally healthy subjects. Once DNA was extracted from the cells, specific primers were used for PCR testing. The amplified gene products were submitted to electrophoresis in polyacrylamide gel and the bands were evidenced with silver nitrate. Products were subsequently submitted to digestion by the Hin1II restriction enzyme. RESULTS: Although some differences were observed in the percentages of genotypes 936 C/C (stage III periodontitis – 61%; stage IV periodontitis – 8%; periodontally healthy subjects – 31%) and C/T (stage III periodontitis – 40%; stage IV periodontitis – 33%; periodontally healthy subjects – 27%) in the groups assessed, this variation was not statistically significant (p> 0.05; Fisher’s Exact Test). CONCLUSION: The results of this study indicate that VEGF 936C/T gene polymorphism was not associated with the presence or severity of periodontitis. Additional studies involving larger samples, as well as the investigation of different polymorphisms of the same gene or other genes, should be conducted in order to broaden the understanding about the role of polymorphisms in periodontal disease.

Published: October 2022

OBJECTIVE: To identify all current treatment methods for symptomatic pericoronitis around the mandibular third molar, in the current context, to guide the clinical practice of dental surgeons. MATERIAL AND METHODS: The review protocol was previously registered (PROSPERO; CRD42019138130). Searches were conducted in MEDLINE [Pubmed], Web of Science, and Virtual Health Library databases, including studies published from 1st January 2000 to 30th June 2019. All studies reporting any treatment for pericoronitis and their efficacy in affected patients, evaluating at least one of the following variables of interest, were included: pain, swelling, trismus, presence and/or amount of bacteria, inflammatory infiltrate, and quality of life. RESULTS: A total of nine studies were included. Interventions included laser therapy, ozone therapy, trichloroacetic acid, curettage and sodium hydrochloride irrigation, electroacupuncture, magnesium sulfate and methocarbamol, hydrogen peroxide mouthwash, green tea and chlorhexidine mouthwash, and antibiotic therapies. Antibiotics were prescribed in the majority of cases reported in these studies. CONCLUSIONS: The present review suggests that the most common treatment for pericoronitis with satisfactory results is the use of antibiotic therapy associated with curettage and chlorhexidine irrigation. Due to the heterogeneity between the studies and methods used, it was not possible to confirm the effectiveness of one treatment in relation to the others. Future clinical trials are recommended for definitive conclusions about treatment for pericoronitis.

Published: October 2022

INTRODUCTION: Periodontal recessions are characterized by the migration of the gingival margin to a more apical position concerning the cementoenamel junction. The prevalence of this mucogingival condition varies according to the study and the population evaluated, but a high prevalence is reported in individuals with excellent oral hygiene. OBJECTIVE: The objective of this study was to evaluate the extent and severity of periodontal recession and its prevalence on students at a dental school (UFMG). Moreover, to identify associated factors and the presence of dentin hypersensitive and aesthetic complains. METHODS: An evaluation was carried out on a convenience sampling of 67 students, mostly female, with a mean age of 23.7 (SD = 1.93). Periodontal recessions were measured considering the buccal and lingual/palatal surfaces of all teeth present. Different clinical parameters of individuals and associated factors were evaluated. For data analysis, absolute distributions and percentages were obtained, and the Mann-Whitney and Kruskal-Wallis association tests were used. RESULTS: The prevalence of periodontal recession was 91% in the studied population, and the most affected group of teeth were the canines. A total of 3,752 surfaces were evaluated, and the presence of recession was observed in 274 (7.30%). None of the parameters evaluated showed a statistically significant association (p<0.05). CONCLUSION: This study concluded that the prevalence of periodontal recession was high, and the evident frequency of recessions in young patients reinforces the need for early diagnosis, not only to improve treatment techniques, but also for prevention, by means of the association with the related etiological factors.

Published: October 2022

INTRODUCTION: Obesity is a chronic disease that impairs health or exacerbates others comorbidities. Among the treatment options, bariatric surgery has shown effective and lasting results. However, patients may experience adverse effects, like gastric reflux, nausea, vomiting, dehydration, vitamin and mineral deficit, and thereby potentiate negative effects of oral manifestation, including dental erosion, caries, periodontal disease, alterations of saliva and oral mucosa. OBJECTIVES: Evaluate oral condition of Unified Health System (SUS) patients at the bariatric surgery service of Hospital Evangélico de Vila Velha (Brazil), analyzing DMFT index, PSR (Periodontal Screening and Recording), salivary pH and the self-perception of oral health. METHODS: An prospective, observational descriptive case series study, conducted in the dental clinic located at Universidade Vila Velha (Brazil), evaluated 24 patients subjected to bariatric surgery. Patients were included in the study after explanation, reading and signing of the Informed Consent Form. The data were collected by means of questionnaires on oral health perception, clinical examination and salivary collection. RESULTS: All evaluated patients had periodontal disease, besides a considerable amount of decayed teeth (7.86%), despite the alkaline pH registered in 83.3% of the sample. Furthermore, 83.3% of the patients stated they did not receive oral hygiene orientation before the gastroplasty. CONCLUSION: The oral health of the participants was unsatisfactory due to the high rates of periodontitis and decayed teeth, even with alkaline salivary pH. Self-perception of oral health does not correspond to the results obtained in the clinical examination. Thus, the inclusion of dentistry in the multidisciplinary team can contribute to health and care of bariatric surgery patients.

Published: October 2022

OBJECTIVE: To evaluate the viability of ozonated water at diff erent temperatures and ozonation regimes over time. MATERIALS AND METHODS: Th ree experiments were carried out with diff erent ozonation protocols. First experiment analyzed the water ozonated at 55 μg/mL for 5 minutes and kept at room temperature or under refrigeration. In the second experiment, the water was kept only under refrigeration and the concentration of O3 in the device was increased to 70 μg/mL. In this phase, the ozonation process lasted 5 or 10 min utes in two diff erent samples. Th e last experiment generated two samples of ozonated water with a device set at 70 μg/mL with an ozonation time of 10 minutes, but with an even lower refrigerator temperature. Th e analysis of the concentration of this gas was carried out through a colorimetric kit, in periods between 5 and 360 minutes, depending on the experiment. RESULTS: When evaluating the infl uence of temperature, the samples of ozonated water that were kept under refrigeration showed greater stability. Th e ozonation time also increased the viability of the solution. When evaluating an even lower temperature of the refrigerator (close to 0 oC) in an optimized concentration of ozonated water 70 μg/mL, the viability of the solution was observed for a period of 2 hours. CONCLUSIONS: Ozonation with bidistilled water at a temperature close to 0 oC at 70 μg/mL for 10 minutes seems to favor the maintenance of the concentration up to 2 hours with potential antimicrobial properties, enabling the viability for its use for therapeutic purposes.

Published: October 2022

OBJECTIVE: Th is study evaluated the presence of halitosis and alterations in salivary parameters in individuals with type 2 diabetes mellitus (DM) and periodontitis (P). MATERIAL AND METHODS: Patients with the following characteristics of both sexes were screened: Group (G)1: 16 patients with DM and with P; G2: 11 patients with DM and without periodontitis; G3: 14 non-diabetic patients with P and G4:15 non-diabetic patients without periodontitis. Physical and laboratory tests were performed, as well as analysis of tongue coating, halitometry and salivary parameters. RESULTS: Th is study showed positive and signifi cant correlations between periodontal parameters and tongue coating with volatile sulfur compounds (VSC) concentrations. Diabetic individuals showed higher levels of salivary urea (p = 0.018) and total protein (p = 0.001), as well as lower calcium levels (p = 0.0001). Groups G1, G2 e G3 showed higher values of salivary phosphate (p = 0.0001). However, there were no signifi cant diff erences between the groups regarding halitosis, salivary fl ow and buff er capacity (p = 0.95, p = 0.06, p = 0.318, respectively). CONCLUSIONS: DM and/or periodontitis infl uenced the presence of tongue coating, which was correlated with VSC parameters. However, DM and periodontitis did not directly infl uence halitosis as well as salivary parameters.

Published: October 2022

INTRODUCTION: Fibrous epulis with ossifi cation is a type of gingival overgrowth that is occasionally encountered by dental practitioners. It should be managed carefully, with deep understanding of its exacerbating factors, to reduce the risk of gingival recession and recurrence. OBJECTIVE: To report the characteristics and management of a clinical case of fi brous epulis with ossifi cation, in the anterior maxillary region on a young female patient, and present a review of the literature. CASE REPORT: A 14-year-old healthy female patient was referred by her general dentist to the Periodontology clinic at the Faculty of Dentistry, University of Otago, Dunedin, New Zealand, for the treatment of a lesion on the buccal gingiva of her right maxillary lateral incisor. Th e lesion initially presented as an asymptomatic non-healing ulcer, which progressed into a pedunculated swelling over a time frame of eight weeks. Th e management of this lesion involved excisional biopsy using surgical scalpel and diode laser, followed by a strict follow-up protocol and oral hygiene reinforcement. CONCLUSION: Review of this patient showed uneventful healing, with minimal gingival recession and no signs of recurrence. Report from histology found that the lesion was consistent with fi brous epulis with ossifi cation. Th is case highlights on the importance of reviewing ulcerative lesions to ensure complete resolution or facilitate appropriate timely referral.

OBJECTIVE: This study aimed to evaluate diabetic individuals with chronic periodontitis who underwent periodontal treatment using clinical parameters and blood tests for fasting glycemia and glycated hemoglobin. MATERIAL AND METHODS: A total of 146 patients with diabetes were initially evaluated. After adopting the inclusion and exclusion criteria, 63 patients were included in the diabetic group (DG). The control group (CG) consisted of individuals with a similar age group to the DG group, a diagnosis of chronic periodontitis, and without systemic involvement. Periodontal clinical parameters and blood tests for fasting glycemia and glycated hemoglobin were performed before periodontal treatment (T1) and 90 days after (T2) treatment. RESULTS: For plaque index and bleeding index, there was a significant difference between the times in both groups. Significant reduction in the percentage of pockets with PD ≥ 6mm after periodontal therapy in both groups. The blood test showed a significant difference in DG group, for fasting glycemia in T1 mean of 168.8 mg/dl and in T2 of 153.1 mg/dl and glycated hemoglobin in 7.6% in T1 and 7.3% in T2 (p ≤ 0,05). CONCLUSION: Non-surgical periodontal therapy improved blood parameters of fasting glucose and glycated hemoglobin in individuals with type 2 diabetes mellitus after treatment.

Published: October 2022

The advent of osseointegration had a fundamental impact on the field of prosthetic rehabilitation of different types of edentulism, from single to multiple failures. However, implants are subject to biological and mechanical complications. Among the mechanical complications, the most frequent is loosening of abutment screws (LAS) in single crowns. As result of the LAS, the gaps between the implant platform and the dental crowns favor bacterial accumulation and can generate a gingival inflammatory, screw fractures and great discomfort to the patient. The objective of this review is to present and discuss the factors and mechanisms associated with the LAS. The bibliographic search was carried out on the website of “Pubmed.gov-National Library of Medicine and National Center for Biotechnology Information in August 2021, using the terms “loosening AND dental implant AND abutment screw” and selecting the first 100 articles by the best recommendation icon (“best match”). The information was grouped by the following factors associated with the LAS: 1) Types of implant-abutment connection; (2) The geometric morphology and the material used and the abutment fabrication; (3) The abutment screw design; (4) The abutment design; (5) implant design, (6) torque value, (7) The material used in making the prostheses, and (8) associated clinical-practical factors. Important knowledge is oriented to clinicians in this review to minimize the occurrence of LAS, however, a critical evaluation shows that the results of the studies present a limited consensus on the theme, so additional studies are needed for ideal conclusions about practices and methodologies for reducing LAS.

Published: October 2022

An exhaustive taxonomic inventory of forest trees of Odisha in the Eastern Ghats of India was made during 2015–2020, which revealed the presence of a total of 501 species of wild and naturalised trees belonging to 284 genera under 80 families. The family Euphorbiaceae was the most species-rich represented by 45 species, followed by Rubiaceae (28), Mimosaceae (27), Moraceae (26) and Meliaceae (23). The genus Ficus (Moraceae) had highest number of 21 tree species, followed by Diospyros (10 species), Syzygium (8 species), Albizia (8 species), Senegalia (7 species), Vitex (7 species) and Terminalia (6 species). Nothopodytes nimmoniana, Alphonsea madraspatana, Lasiococca comberi, Siphonodon celastrineus, Searsia paniculata, Syzygium schmidii, Cassipourea ceylanica, Prunus pygeoides, Sonneratia griffithii, Eriolaena hookeriana var. viridis, Dimorphocalyx glabellus, Garcinia xanthochymus and Litsea glutinosa have been identified as regionally threatened species needing conservation intervention. Cocculus laurifolius is reported here as a new distributional record for the state. Field observation on the occurrence and dominance of tree species in different forest types of Odisha has been discussed. A checklist of the tree species of Odisha is presented in this article, along with the correct botanical name, synonym(s), local name, flowering and fruiting time, locality of occurrence and citation of voucher herbarium specimens.

-Laplacian with nonsmooth potential. We establish the existence of homoclinic solutions by using variational principle for locally Lipschitz functions and the properties of the generalized Lebesgue-Sobolev space under two cases of the nonsmooth potential: periodic and nonperiodic, respectively. The resulting problem engages two major difficulties: first, due to the appearance of the variable exponent, commonly known methods and techniques for studying constant exponent equations fail in the setting of problems involving variable exponents. Another difficulty we must overcome is verifying the link geometry and certifying boundedness of the Palais-Smale sequence. To our best knowledge, our theorems appear to be the first such result about homoclinic solution for differential inclusion system involving the

Integral Representations and Quadrature Schemes for the Modified Hilbert Transformation
Authors: Zank Marco
Published: October 2022

We present quadrature schemes to calculate matrices where the so-called modified Hilbert transformation is involved.
These matrices occur as temporal parts of Galerkin finite element discretizations of parabolic or hyperbolic problems when the modified Hilbert transformation is used for the variational setting.
This work provides the calculation of these matrices to machine precision for arbitrary polynomial degrees and non-uniform meshes.
The proposed quadrature schemes are based on weakly singular integral representations of the modified Hilbert transformation.
First, these weakly singular integral representations of the modified Hilbert transformation are proven.
Second, using these integral representations, we derive quadrature schemes, which treat the occurring singularities appropriately.
Thus, exponential convergence with respect to the number of quadrature nodes for the proposed quadrature schemes is achieved.
Numerical results, where this exponential convergence is observed, conclude this work.

. The nonlinearity is critical or subcritical growth in view of Trudinger-Moser inequalities. We first obtain the existence of a solution in the subcritical exponential growth case with positive energy by using minimax techniques combined with the Trudinger-Moser inequality. In the critical case, the associated energy does not satisfy the condition of compactness. We provide a new condition for growth, and we stress its importance to check the compactness level.
Patterns of Technological Entrepreneurship and Their Determinants: Evidence from Technology-Based Manufacturing Firms in China
Authors: Liu Jingjiang , Hu Jianhao , Wu Dong , Chen Jin
Published: October 2022

In this study, we argue that managing technological entrepreneurship effectively is crucial for firms’ competitive advantage and high performance. By using an inductive approach of a multiple-case study of Chinese technology-based manufacturing firms, we identify four complementary patterns of technological entrepreneurship (i.e. in-house R&D, R&D acquisition, R&D alliance, and R&D contracting) and find that possessing the uniqueness of knowledge assets and technological capabilities and capturing the value of knowledge assets and technological capabilities are the major determinants for firms to choose these patterns. Our study develops an integrative framework of technological entrepreneurship for emerging economy firms. Implications for theory, practice, and policy are discussed.
Quality control of SIRGAS ZTD products
Authors: Mackern María Virginia , Mateo María Laura , Camisay María Fernanda , Rosell Patricia Alejandra
Published: October 2022

The SIRGAS-CON network currently has more than 450 continuous GNSS stations, and it is used for geodetic purposes. In atmospheric studies, it is used for ionospheric monitoring and for the estimation of zenith tropospheric delays (ZTDs). From the Neutral Atmosphere Analysis Center of SIRGAS, Centro de Ingeniería Mendoza Argentina, the final tropospheric products of this network are generated after several stages of quality controls and filtering, in order to be published on a daily basis in the official website of SIRGAS, since 2014 (https://sirgas.ipgh.org/en/products/tropospheric-delays). These products arise from adjusting the solutions estimated by different SIRGAS analysis centers. Prior to the combination, a quality control of the individual solutions is carried out, based on the precision estimator of each parameter and an internal control of each solution with respect to the combined value. In this work, we show the quality control process of the inputs, the selected tolerance and its justification. The internal consistency analysis of tropospheric parameters for a period of 7 years was carried out. We also exposed the improvements in the estimation of tropospheric parameters implemented during 2021 and its impact in the generation of the final ZTD products (in 99% of the stations the mean standard deviation of ZTD is less than 1 mm).

Authors: Li Jun-Xia , Xiong Lin-Yuan , Xu Xiao-Jie , Liu Chang , Wang Zheng-Guo
Published: October 2022

Triclopyr ethyl ester (1) has been co-synthesized through one-pot solvothermal reaction and the crystal structure has been determined by single crystal X-ray structure analysis. The compound C18H16Cl6N2O6 crystallizes in the monoclinic crystal system, P21/c space group with unit-cell parameters: a = 4.9615(2) Å, b = 30.9297(14) Å, c = 15.9155(10) Å, β = 91.466(4)° and Z = 4. Each unit cell is composed of two discrete, similar but reversely arranged triclopyr ethyl ester organic molecules. In the 3D packing plot, 1 is further assembled into a network structure via rich Cl⋯Cl halogen bond interactions. In addition, the crystal structure, the flexible conformation of phenoxy methylene group of 1 has been carefully compared and discussed with those of triclopyr acid.
Коммуникативная онтология А. Пушкина в одесской лирике. «Впечатленья бытия» и текст как инобытие автора

Published: October 2022

A. Pushkin's Communicative Ontology in Odessa lyrics. “Impressions of Being” and the Text as the Author's Otherness. The article is devoted to the study of Pushkin's ontology with application of communicative ontology. The methods of communicative ontology in the works of Yu. Lotman about the Odessa lyrics of A. Pushkin are investigated, the parameters of the ontological dimension of communication are systematized. The substantiation of Pushkin's “Odessa text” as an otherness is carried out as a correlation of the author's text with the system of contexts forming it. This view contributed to Bonapartism contexts’ classification, Orthodoxy and the Faustian text as philosophical and artistic parameters of Pushkin's ontology. The prospects for the development of Yu. Lotman's ideas and methods for the analysis of Bonapartism and its para-doxical meaning for Russian history, Orthodoxy as a philosophy of religious artistry and the Faustian text are shown.
Метафоризація концепту життя в мові української поезії

Metaphorization of the concept of life in the language of Ukrainian po-etry. The article discusses the metaphor "life" in Ukrainian poetry of the 20th - early 21st century. The source of the material was the works of Ukrainian writ-ers from mainland Ukraine and the Diaspora. Using the method of metaphori-cal modeling, the key models of the metaphors of "life" in the Ukrainian poetry of the analyzed period were identified and characterized, and individual au-thor's metaphors that were based on them were analyzed. The change of meta-phors is explained, the specificity of their meanings is described. It has been established that the metaphors recorded in the Ukrainian poetry of the XX - Art. XXI Art. reveal a different understanding of life by each writer, which is due to a complex of external and internal factors.
Kajkavska grafija u 18. stoljeću
Authors: Dudás Előd
Published: October 2022

The Kajkavian Croatian orthography in the 18th century. This paper presents the historical development of Kajkavian Croatian orthography in the 18th century. The main goal of this paper is to present the tradition of the Kajkavian Croatian orthography, as well as to introduce the use of graphemes in detail. During the Middle Ages the church counted as the centre of the literacy, thus it is obvious that the ecclesiastical Latin pronunciation defined the evolution of the individual national languages’ orthographies. From this point of view, the Croatian is a special case, as in the Middle Ages the Southern Croatian areas were strongly affected by the Italian, while in the northern areas, overlapping the Archdiocese of Zagreb, a strong Hungarian impact can be observed. In the northern areas the Latin /s/ phoneme is pronounced in a Hungarian way, as [ʃ] or [ʒ].
К вопросу концептуализации бинарных оппозиций и «противоречий» в семиотике литературы Ю. М. Лотмана
Authors: Кроо Каталин
Published: October 2022

В статье продолжается изучение своеобразия концептуа-лизации Ю. М. Лотманом бинарных противопоставленностей в его иссле-дованиях по семиотике культуры. Бинарные оппозиции рассматриваются в контексте различения дуальных и тернарных моделей «в динамике русской культуры» с установкой на литературу (объект изучения) и ин-терпретацию научного описания (метатекст). В первой части статьи толкуются работы Лотмана–Успенского (1977), Лотмана «О русской литературе классического периода (Вводные замечания)» (1992), а во вто-рой части – в центр внимания ставится материал чтения Лотманом романа в стихах Пушкина «„Евгений Онегин”: Спецкурс. Вводные лекции в из-учение текста» (1975). По ходу изложения понятие бинарности оттеняется в свете определения Лотманом в его «Спецкурсе» механизмов смыслопо-рождения в целостной семиотической системе литературного текста, подверженных толкованию не просто в понятийном поле «контрастнос-ти» и «взаимоисключения», но также в поле «неадекватности», «несовпа-дения», «разнородности». Происходит переустановка акцента на концеп-туализацию дифференциального признака, смены условности и возникно-вения плюральности семиотической системы.
Лотман и Гуковский. Диалог в историко-культурном контексте
Authors: Кузовкина Татьяна Дмитриевна
Published: October 2022

В статье 1) дан хронологический очерк отзывов Ю. М. Лотмана об идеях и преподавательской деятельности Г. А. Гуковского: от времени довоенного и послевоенного студенчества до позднейших мему-арных текстов; 2) рассмотрены наиболее значимые сюжеты полемики Лотмана с историко-литературными концепциями Гуковского в области истории русской литературы; 3) введены в научный оборот фрагменты неопубликованных лекций Лотмана 1960 года, ставших основой для его первой монографии в области структурной поэтики. Лекции свидетель-ствуют о сильном влиянии идей Гуковского о единстве содержания и фор-мы в художественном произведении на структуралистическую теорию Лотмана.
Стихотворение Давида Самойлова «Поэт и гражданин» в свете рецепции «Войны и мира» Льва Толстого
Authors: Александрова Мария Александровна
Published: October 2022

David Samoilov’s poem “The Poet and the Citizen” in light of the per-ception of Leo Tolstoy’s “War and Peace”. There are in-depth studies of the programmatic poem “The Poet and the Citizen” by David Samoilov from the per-spective of genre tradition and the dialogue with contemporary poets. The reflection on Tolstoy’s legacy as the ideal of the unity of the “children of man-kind” has been a stage in the investigation process in question. However, Samoilov’s stance with respect to Tolstoy’s humanistic precept in the events of the 20th century is still understudied. The present paper analyses the transfor-mation of Tolstoy’s “folk thought” into Samoilov’s intense reflection on the people at war and its embodiment in the imagery of the poem “The Poet and the Citizen”.
