Hızlandırılmış UV Yaşlandırma ile Odunda Meydana Gelen Renk, FTIR ve Mikroskobik Değişimlerin Belirlenmesi
Authors: SÖZEN Eser
Published: August 2021

Yağmur, güneş, rüzgâr gibi doğal şartlar ahşap malzemenin fiziksel, kimyasal ve mekanik özelliklerinde değişimlere neden olmaktadır. Bu değişimler çoğunlukla olumsuz olarak nitelendirilmektedir. Ancak, bazı durumlarda bu olumsuz değişimler doğallığı ifade etmesi veya bir sonraki işlem için gerekli olmasında dolayı tercih edilebilmektedir. Bazı mobilya ve iç mekan tasarımlarında eskitme olarak nitelendirilen ahşaplar özellikle tercih edilmektedir. Bu çalışmada, kayın (Fagus orientalis L.) odununda hızlandırılmış UV yaşlandırma testi sonrasında renk değişimi, lignin oranı ve hücre çeperinde meydana gelen değişimler incelenmiştir. Renk ölçümü, ISO 7724 (1984) standartlarına uygun olarak UV yaşlandırma testi öncesinde ve sonrasında yapılmıştır. FTIR analizi sonucunda 945-1132 absorbans değerleri arasındaki hemiselüloz ve lignin oranında kontrol örneklerine göre %14,78 azalma meydana geldiği görülmüştür. Hücre çeperinde meydana gelen değişimler SEM analizleri ile enine kesit ve teğette ayrı ayrı incelenmiştir. Enine kesitte UV sonrası kontrol örneklerine göre belirgin çatlakların oluştuğu görülmüştür. Boyuna yönde ise paranşim hücrelerinde dağılmaların olduğu saptanmıştır.
Leadership und Verantwortung
Authors: Huppenbauer Markus
Published: August 2021

Unternehmen werden angeklagt, Menschenrechte und Umweltschutzstandards zu wenig zu respektieren. Managern wird vorgeworfen, nur ihr eigenes Interesse oder das der Investoren im Auge zu haben und so die berechtigten Interessen ­anderer Personengruppen zu missachten. Kurz, es mangle an ethischer Verantwortung in der Wirtschaft.

Wie sollen Führungsverantwortliche mit diesen Herausforderungen umgehen? Markus Huppenbauer vertritt einen pragmatischen und ­libera­len Ansatz: Weder ethischer Aktivismus noch ­defensive Reaktionen sind angesagt. Es gilt vielmehr, die ethischen Herausforderungen in der Wirtschaft mit Besonnenheit und ­Vernunft anzugehen. Das Buch vermittelt die spezifischen Kompetenzen, um ethisch fundierte Entscheidungen zu treffen. Ein besonderer Fokus liegt auf Fragen der Unternehmensführung und Führungsverantwortung.

Moralische Normen und Werte sind auch in der Wirtschaft essentiell, aber sie lassen mehr Spielräume zu, als man gemeinhin meint. Staatlich-rechtliche Regulierungen sind manchmal nötig, besser aber ist die Selbstverpflichtung der wirtschaftlichen Akteure.
Finanzkrise: Kehrtwende zur Zukunft
Authors: Kreikebaum Hartmut , Kreikebaum Marcus
Published: August 2021

Was ist notwendig, um künftige Krisen wie die Finanzkrise von 2008 zu vermeiden? Wie finden wir eine Balance zwischen dem einseitigen, am kurzfristigen Eigennutz orientierten finanzmathematischen Kalkül und den Prinzipien und Regeln für ein nachhaltiges, menschendienliches Wirtschaften? Was können wir aus der Geschichte lernen?

Diese Fragen standen im Zentrum der Gespräche von Hartmut Kreikebaum und seinem Sohn Marcus Kreikebaum. In ihrem Buch rekapitulieren sie die Ursachen und Folgen der Finanzkrise und stellen zahlreiche Lösungsansätze vor:

- ordnungspolitische Ansätze,

- pragmatische finanz- und personalpolitische Ansätze,

- ökologische Lösungsansätze.

Die Autoren plädieren für eine »Renaissance der Vernunft« im Sinne einer Bejahung der menschlichen Verantwortung, den selbstzerstörerischen Tendenzen der Marktkräfte Einhalt zu gebieten und sie auf das Gemeinwohl umzulenken – damit die Kehrtwende zur Zukunft gelingt.

Ôrí, un ritual poético-audiovisual: en busca de la identidad afrobrasileña perdida
Authors: Paganelli Pia
Published: August 2021

Ôri (1989) es un documental brasileño dirigido por Raquel Gerber que registra los tránsitos culturales entre Brasil y África a través de la vida personal de la historiadora y militante negra Beatriz Nascimento (1942-1995) y su relación con la trayectoria del movimiento negro en Brasil, con el objetivo de trazar una identidad negra dentro de dicho país. El presente trabajo propone un análisis del documental enmarcado en la perspectiva del Atlántico Negro de Paul Gilroy y en los Estudios Culturales de Stuart Hall, para dar cuenta de la discusión que propone Nascimento en torno a la identidad negra en las Américas (como fenómeno transnacional); y en Brasil (como fenómeno nacional), a partir de sus estudios sobre el concepto de quilombo, al que entiende como categoría fundamental en el proceso de autoafirmación étnica y nacional.
Unamuno, Borges y la música. De la paradoja antimodernista al equilibrio simbolista
Authors: Cantero María Paula
Published: August 2021

De todos los aspectos que comparten Borges y Unamuno, este estudio hace hincapié en la concepción musical de su poesí­a. Unamuno ha sido siempre un autor difí­cil de catalogar, por eso la crí­tica lo ha señalado como un autor simbolista tanto como antimodernista. Por su parte, Borges ha mostrado una postura crí­tica ante sus contemporáneos modernistas, así­ como ante la obra de Unamuno, pero su poética coincide también con las teorí­as simbolistas. La particular relación que la poesí­a de ambos escritores ha establecido con la música nos permite ligarlos a ambos movimientos. Así­, es posible ver una evolución en su obra poética, que es paralela a su vida.
Regionalismo orgánico: humanidad, naturaleza y capitalismo en Juan O’Gorman y Nicolás Cabral
Authors: Selgas Gianfranco
Published: August 2021

En este ensayo, propongo leer la configuración de lo que describo como ‘regionalismo orgánico’ en la novela Catálogo de formas (2014), del escritor argentino-mexicano Nicolás Cabral. Desarrollo la noción de ‘regionalismo orgánico’ tomando como punto de partida los ensayos sobre arquitectura organicista del pintor y arquitecto mexicano Juan O’Gorman (1905-1982). Argumento que a través de sus ensayos y su práctica artístico-arquitectónica, O’Gorman propuso una visión simbiótica entre naturaleza y cultura, crítica de los preceptos euromodernos y capitalistas que son recuperados tanto temática como formalmente en la novela de Cabral. A diferencia de los estudios que leen Catálogo de formas como una obra metatextual con la de O’Gorman, señalo que, leída como expresión del ‘regionalismo orgánico’, la novela tematiza y formaliza las relaciones orgánicas entre humanidad y naturaleza con los efectos de las prácticas extractivistas como fondo espacio-temporal.
"Más que un medio de locomoción”: estética y ética del avión en la literatura moderna
Authors: Nitsch Wolfram
Published: August 2021

Desde 1909, cuando el aviador francés Blériot logró cruzar el Canal de la Mancha, el avión no ha dejado de fascinar a los escritores. Dos aspectos del vehí­culo recién inventado despertaron un interés particular en la historia literaria de la aviación. Si para varios poetas y novelistas modernos el avión es “más que un medio de locomoción”, como observa el poeta piloto Saint-Exupéry, lo es a la vez por razones éticas y estéticas. Por un lado, se celebra el aero ­plano como un medio de acción que posibilita transgredir los lí­mites del mundo y de sí­ mismo; por otro, se presenta como un medio de percepción que permite ver la tierra y el cielo de una manera distinta. El presente artí­culo trata de aclarar estos dos ví­nculos entre la aeronáutica y la literatura mediante algunos textos publicados antes y después de los bombardeos de la segunda guerra mundial, en particular La vuelta a Europa en avión (1929) de Manuel Chaves Nogales, Terre des hommes (1939) de Antoine de Saint-Exupéry, Estrella distante (1996) de Roberto Bolaño y Le Jardin des Plantes (1998) de Claude Simon.

'When the cat is away, the mice will play': the political ecology of tobacco production and manganese mining in Nansanga farm block in Zambia
Authors: Chilombo Andrew , van der Horst Dan
Published: August 2021

Large-scale land acquisitions (LSLAs) have emerged as an important policy issue in development discourse. Governments in host countries play a critical role in engineering policy landscapes for enclosing local community resources for capital accumulation by business entities with more financial resources and access to power. Case studies have highlighted failed implementation of LSLA deals, resulting in cancellations, scaling down, abandonment or change of investment business models. However, few attempts have been made to understand what accounts for such failures and what happens when both state policy and private sector implementation of land deals fail. Taking Nansanga farm block, a government of Zambia-led LSLA deal currently in limbo, this article presents a study that aimed at understanding the political ecology of tobacco production and manganese mining as opportunistic economic activities – that is, activities that are taking advantage of new infrastructure created by an otherwise 'failed' government project and flourishing in an area where local people's rights were previously protected through customary tenure. Drawing on stakeholder interviews, the study shows that the government's role in the development of Nansanga vanished; creating a development vacuum that opened the door to opportunistic tobacco production and open pit manganese mining. Tobacco and mining, heavily extractive as they are of forest resources, have emerged as double-edged swords: in the short term increasing financial inflows and job creation on one hand, and, on the other, leading to flight from production of traditional crops, deforestation and land degradation, anomie and deracination as some land use and land users are (re)defined.

Published: August 2021

Background and Purpose

There are few studies addressing the rate of application of bone allograft and its use; hence, the present study aimed to compare the clinical outcomes of using bone allograft and autograft in patients with long bone fracture.

Method

In this clinical trial study, all patients who underwent bone graft surgery with the diagnosed long bone fractures of upper and lower limbs at Shahid Beheshti Hospital were included in the research. Patients were divided into two groups, autograft and allograft, according to type of treatment. They were evaluated for their union, complications, and range of motion.

Results

In the present study, 124 people were studied. Among them, 100 patients were eligible and included in the study. The allograft and autograft groups did not have any statistical significant differences in terms of age, sex, location, causes of fracture, and surgical methods. Results of the present research on patients in terms of fracture site indicated that there was no significant relationship between the two groups in rate of union (P = 0.18). Allograft and autograft had no difference in terms of complications. Studied range of motion indicated that patients were not different in terms of their ranges of motion.

Conclusion

Based on findings of the present study, allograft could be a suitable substitute for the autograft. The two graft methods were similar in terms of complications, union, and ranges of motion.
Role of the Histological Variant for the Prognosis and Course of the Focal Segmental Glomerulosclerosis
Authors: Yordanov M. , Ananiev J. , Robeva R.
Published: August 2021

The focal segmental glomerulosclerosis is characterized by a morphological heterogeneity, most likely reflecting different pathogenetic mechanisms. The Colombian classification distinguishes five morphological types – non-specific (not otherwise specified or classical), perihilar, cellular, a tubular pole (tip) one and a collapsing one. Eighty-one (81) patients were studied. Their distribution according to the histological variant showed the highest frequency of the non-specific (classical) variant – 70.4%, followed by the perihilar variant – 27.20%, the cellular variant – 1.2% and the collapsing variant – 1.2%. No patients with tip lesions were identified. There were significant differences in the creatinine levels and the glomerular filtration rate (GFR) at the beginning and at the end of the follow-up between patients with the perihilar and the non-specific variants. Patients with the perihilar variant had a better treatment response with a high percentage of patients achieving complete remission – 59.1%. Patients with the non-specific variant had a high chance of treatment failure – 26.3% had no effect from treatment. The results of the study give grounds to assume that the histological variant affects the clinical picture, course and therapeutic response in patients with focal segmental glomerulosclerosis. It could be used as a prognostic marker of disease behavior and guide the clinician in treatment decisions.
Comparative Efficacy, Safety and Tolerability of Olanzapine and Blonanserin in Patients with Schizophrenia: A Parallel Group Study
Authors: Chattopadhyay S. , Roy U. , Biswas S. , Roy P. , Mandal P.
Published: August 2021

Background

The antipsychotic olanzapine is a first-line drug in the treatment of schizophrenia while blonanserin is indicated in resistant cases of schizophrenia when the first line antipsychotics have failed. There are very limited studies available world-wide as well as in India that compare blonanserin with other antipsychotics in the setting of schizophrenia.

Aims

To study the efficacy, safety and tolerability of olanzapine and blonanserin in Schizophrenia. Settings and Design: The study was a prospective, observational, parallel group study done on schizophrenia patients aged between 18-50 years of both sexes at an outpatient Department of Psychiatry, in a tertiary medical college. The study was conducted from February 2015 to October 2016, with follow ups at weeks 4, 8 and 12.

Materials and Methods

The efficacy parameters were measured by the Brief Psychiatric Rating Scale (BPRS) and the Clinical Global Impression (CGI) rating. The safety parameters included the vital signs, haematological profile, lipid profile, blood sugar monitoring. Adverse drug reactions and compliance to therapy was observed through-out the study period. Appropriate statistical tests were applied to detect any significant within and between group differences using Microsoft Excel 2007 and SPSS version 17.

Results

There was significant decrease in the mean total score on the BPRS and CGI-S in the blonanserin arm at the 2nd and last follow up visit (p value < 0.001). Compliance was good in both groups (≤ 20% missed pills). Overall, 77 treatment-emergent adverse events were present from 56 patients. Twenty three subjects of the blonanserin arm and 33 subjects in the olanzapine arm at least experienced one adverse event (p = 0.006), metabolic adverse effects were more common with olanzapine, whereas insomnia, headache and somnolence were more often seen with blonanserin.

Conclusions

In the present study, blonanserin provided significantly better outcomes than olanzapine with respect to BPRS, CGI-S scores.
Separation of waste plastic resulting from electrical products by forced aeration flotation
Authors: Ghinea Cristina , Paduret Sergiu
Published: August 2021

The separation of four waste plastic samples - Polyvinyl chloride (PVC), Acrylonitrile butadiene styrene (ABS), Polycarbonates (PC), and Polyamides (PA) resulting from electrical products in three bicomponent plastic mixtures (PVC-ABS, PVC – PA, and PVC - PC) was performed by using four different flotation solutions (5%, 10%, 20%, and 30% concentration) of CaCl2. Furthermore, the waste plastic samples were analyzed in terms of density, specific volume, particle size, initial water content, and water absorption capacity, while the flotation solutions were analyzed in terms of pH, density, electrical conductivity, and refractive index. Results showed that from the analyzed waste plastic samples, the PVC sample has the highest density (1.3823 g/cm3), followed by PC (1.2034 g/cm3) and PA (1.0607 g/cm3), while the ABS (0.9723 g/cm3) presented the lowest value. The highest recovery rate was obtained for the PVC samples (98.10 % - 99.75 %) when it was mixed with ABS, whereas the highest purity was measured for ABS samples (98.29 % - 99.76%) in the case of the same mixture.
Post-flood field investigation of the June 2020 flash flood in the upper Muráň River basin and the catastrophic flash flood scenario
Authors: Pekárová Pavla , Mészáros Jakub , Miklánek Pavol , Pekár Ján , Siman Cyril , Podolinská Jana
Published: August 2021

After a dry spring, in June 2020 several intense storms occurred at the headwaters of the small basins of the Muráň and Zdychava rivers in the territory of the Muránska planina National Park (Slaná River basin, Slovakia). In the first part of the study– according to a hydrological survey made by the authors after the flash flood – the peak discharge was reconstructed at several Muráň River profiles. Next, the flash flood waves were reconstructed by the rainfall-runoff model NLC (non-linear cascade). The results of modelling based on field investigations show that, despite the extreme precipitation event (108 mm per 1 hour at the precipitation gauging station at Predná Hora), the peak flow rates were not exceptional in selected profiles on the Muráň River. The fact that extreme precipitation above 120 mm fell in a relatively very small area at the division of the Muráň and Zdychava rivers’ water contributed to this result. In the second part, a catastrophic 1000-year rainfall event scenario on the Zdychava River basin has been prepared. In analysing time series and identifying T-year daily rainfall depths, daily data was used from six precipitation stations in the vicinity of Muránska planina. Then, the 1000-year discharge of the Zdychava at Revúca was simulated by the calibrated NLC model. In such an extreme precipitation scenario, the peak flow rate would reach 105.15 m3 s−1, i.e. with a specific runoff of 1.78 m3 s−1 km–2. The total runoff in an 18-hour period would be 1.119 million m3, representing 21.11% of the rainfall (5.301 million m3).

The permeable pavement is a compensatory drainage technique for urban waters that aims to control runoff and to ensure ideal hydrological conditions. This work had as main objectives to evaluate the infiltration capacity of a permeable pavement (PP) at real scale, through analytical and numerical modeling. It relies on water infiltration experiments and related modeling for the hydrodynamic characterization of the coating layer (saturated hydraulic conductivity, Ks
, and sorptivity, S). A large panel of analytical and numerical models was considered, and several estimates were obtained. Then, the criteria for the evaluation of the maintenance requirement of the permeable pavements were computed for all the Ks
-estimates considering the NCRS standards (assessment of permeability levels). The results indicated nice fits and accurate estimates for both the saturated hydraulic conductivity and the sorptivity. However, the Ks
-estimates depended on the considered model and led to contrasting results in terms of classification. For 8 of the 9 models, the value of the Ks
-estimate leads to the classification of “Group A” of the NCRS soil classification, meaning a very permeable material. In contrasts, the last method (numerical inverse modeling) classified the permeable pavement as “Group D”, i.e., soils with low permeability. Those results show the importance of the selection of characterization methods regarding the assessment of the hydrological classification of permeable pavements.
Power Module Temperature in Simulation of Robotic Manufacturing Application
Authors: Bormanis O. , Ribickis L.
Published: August 2021

The paper presents a lifetime consumption estimation model of 6 degrees of freedom industrial robot arm. The primary goal of the research is to provide estimated lifetime data of semiconductor power modules of robot axis power supply circuit, providing new opportunities for cost-saving, predictive maintenance, with highly customized input for different manufacturing applications. Evaluation of thermal stress and estimation of isolated gate bipolar transistor current are completed, based on MATLAB model translating KUKA robot program code to electrical energy consumption, which is a novel approach. Energy losses are considered in the model to provide accuracy of the inverter load current. The simulation results prove that lifetime consumption depends on a robot application type, for more agile movement programs with large power amplitudes, such as handling, the degradation in power modules is significant compared to slower applications, such as gluing or welding. Various options for future development are suggested and considered in the paper.

Published: August 2021

The purpose of this paper is to demonstrate the performance of agricultural sectors in the Association of Southeast Asian Nations (ASEAN) countries using selected criteria, to identify the deficiencies in agricultural policies, to explore competitive advantages and to guide food and nutrition policies. The analyses of this research use the secondary of time series data between the years 1967 - 2016 from 10 countries including; Brunei Darussalam, Cambodia, Indonesia, Laos PDR, Malaysia, Myanmar, Philippines, Singapore, Thailand and Vietnam which are the member of ASEAN. This research uses the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method and the data used for the mentioned countries include the following criteria; total agricultural production value of the land, self-sufficiency of animal products criteria, self-sufficiency of crop products criteria, rural population rate, greenhouse gas emissions from agriculture, and value of foreign trade in agricultural products. The result of proximity coefficients calculated with the TOPSIS method, which according to the number of proximity and maximum benefit analysis should be done according to the order of preference. It is stated that Thailand, Philippines and Indonesia were the most successful countries in the agricultural policy performance in 1967. As for last decades, Malaysia became the most successful country in agricultural policy performance. We can infer from the results that Malay industrial sector triggered the agricultural sector by supplying financial investment atmosphere.

Authors: Solonshchikov Pavel , Savinykh Peter , Ivanovs Semjons
Published: August 2021

Feeding young animals is a very important stage during their growing-up period, but in order to provide them with essential nutrients, they are fed with liquid feeds, whole milk substitute in particular (WMS). The technique for reconstituting WMS consists of dissolving it in water followed by mixing, but it is significant to follow the cooking recipe strictly, so it is necessary to develop a system with a feeding (dosing) device that will make it possible to solve this problem. Theoretical and experimental studies of the feeding device have been conducted in order to optimize the technological process of mixing liquid feed. Theoretically, the quality of determining the mixture during dosing was established for the purpose of further research. The influence of the design and technological parameters of the feeding device was experimentally studied, and its efficiency was evaluated. It was found that as the inclination angle α increases from 67,50 to 700, the rotation speed n being from 850 to 1500 min−1, the maximum probability of staying in the tolerance field ΔP=96% is reached, and feed discharge Q ranges from 540 to 660 kg h−1.

Published: August 2021

Birch plywood has a wide range of applications for interior and exterior use. The demand for plywood with improved fire protection properties and good visual appearance is increasing year by year. The impregnation at high pressure of the whole plywood panels is one of the options to achieve it. The aim of this study was to develop good visual looking birch plywood product for interior design purposes as well evaluate different influencing factors to reaction to fire properties of fire-retardant treated birch plywood. This study consists of three parts. At the first stage, high pressure industrially impregnated plywood properties were studied by two influencing factors – distribution of fire retardant in plywood panel plane and sanding process influence on reaction to fire performance of product. At the second stage, seven different industrial finishing systems were selected for covering high-pressure impregnated birch plywood and their effect on fire reaction performance was studied. In addition, two surface coating systems were studied on standard birch plywood substrate. At the third stage, intumescent coating consumption effect on reaction to fire performance was studied. The reaction to fire performance of birch plywood was evaluated by performing a flammability test using the Single Burning Item test according to EN 13823:2010. It was found that high pressure impregnation of plywood cannot ensure even saturation of fire retardant throughout the sheet, which significantly affects the fire performance of product. The impact of different finishing materials to reaction to fire performance has been described by the results of this research.

The taxonomy and ecology of Cortinarius subgenus Myxacium section Colliniti in Fennoscandia is treated. Most species of this group have their optima in oligotrophic habitats, and play an important role in upper boreal and Arctic-alpine regions. Variation in spore morphology is subjected to numerical treatment. Relevant nomenclatural types and protologues for classical names are examined.

Presence of clamp connections is stated to be an important diagnostic character towards the most closely related section, Defibulati. Also, SEM pictures have revealed a significant difference in the spore ornamentation between the two groups. Spore shape and size provide important diagnostic characters for separation of the different taxa of section Colliniti, as shown by scattergrams. The most distinctive species in this respect are found to be C. mucosus, with characteristically narrow spores, and C. collinitus with larger spores. The species concept within the group is discussed.

Seven Fennoscandian species are recognized and their taxonomy and ecology are discussed. C. septentrionalis (type from Norway) and C. fennoscandicus (type from Finland) are described as new. Both species are common in upper (northern) boreal mountain birch (Betula) woodlands and under the low shrub Betula nana in the low alpine and arctic zones. The status of Agaricus collinitus Sow: Fries is discussed in more detail.
Fertilization effects and vegetation-environment relationships in a boreal pine forest in Åmli, S Norway
Authors: Skrindo A. , Økland R.H.
Published: August 2021

Species composition in 144 sample plots, each 1 m2, in 35-year old pine forest in Åmli municipality in Aust-Agder, S Norway, was recorded. The plots were systematically placed within the 12 blocks in a factorial fertilization experiment [addition of nitrogen (2 levels), magnesium and phosphorus], initiated six years before our analysis was carried out. At each sample plot, 28 explanatory variables were recorded. Results obtained by parallel use of three ordination methods demonstrated existence of one main coenocline from lichen-rich sites to sites rich in mosses and ericaceous species. The coenocline was interpreted by analysis of correlations between plot positions and explanatory variables, and by analysis of spatial structure using geostatistical methods, as a fine-scale moisture complex-gradient. Important correlated variables were: humus depth, tree density and canopy closure, and microtopography.

Small, but significant effects of fertilization by nitrogen and phosphorus on the vegetation was demonstrated and discussed.

Background:

To detail two cases of sarcomatoid urothelial carcinoma (UC) with rapid progression, disseminated metastases, and early death, detailing the results of somatic tumor profiling using next-generation sequencing (NGS).

Case Series:

The first case presented is a rare case of UC of the renal pelvis with osteosarcomatous differentiation and venous tumor thrombus in a 65-year-old man found to have a heterozygous germline variant of unknown significance in the neurofibromatosis-1 gene. The second case is a 72-year-old woman with sarcomatoid UC of the bladder. Herein, we discuss the presentation and clinical course, histology, immunohistochemical profiles, and somatic tumor testing results. We then review the literature regarding this rare and aggressive entity, detail options for optimal management, and address the role of molecular profiling in these cases.

Conclusion:

Sarcomatoid UC is a rare and aggressive entity. NGS may be useful in these cases to guide systemic therapy.
РОЛЬ МУЗИЧНОЇ КУЛЬТУРИ В ПРОЦЕСАХ УКРАЇНСЬКОГО НАЦІЄТВОРЕННЯ У ГАЛИЧИНІ (ДРУГА ПОЛОВИНА XIX – ПОЧАТОК XX ст.)

Метою пропонованого дослідження є визначення ролі і місця музичної складової у процесах українського культурного націєтворення у Галичині в умовах панування монархії Габсбурґів. Методологія дослідження побудована на комплексному застосуванні історичного, ретроспективного та культурологічного методів. Історичного – у висвітленні історичних реалій соціо-політичного буття галицьких українців в умовах імперії Габсбургів. Ретроспективного – в аналітичній реконструкції культурних форм публічної реалізації національного самоусвідомлення українців Галичини на межі XIХ–XX ст. Культурологічного – при естетичній оцінці мистецьких явищ та форм, що народжувалися в культурному просторі підавстрійської Галичини досліджуваного періоду і сприяли українському націєтворенню на цих теренах. Наукова новизна здійсненої розвідки полягає у виокремленні культурно-мистецької сфери як аналітичної оптики, що дає змогу більш повно осмислити й оцінити історично вагомі процеси формування української ідентичності галичан у мультикультурному соціумі імперії Габсбургів. Висновки. У розбудові української національної культури у Галичині другої половини XIХ – початку XX ст. вагоме місце відігравала діяльність численних музичних товариств, а також творчість галицьких композиторів, пов’язана з поетичним словом Т. Шевченка. Ці фактори стали вагомим чинником подолання германізації і полонізації галицького населення, що перебувало в умовах, де українська мова була усунута з публічного життя і деколи навіть з домашнього вжитку. Частково цю проблему вдалося подолати завдяки творчій діяльності О. Нижанківського, Д. Січинського, Ф. Колесси, Г. Топольницького, Я. Лопатинського. Згадані композитори зверталися до текстів відомих письменників, які репрезентували українську літературу в підросійській Україні (О. Кониський, Б. Грінченко, Леся Українка, А. Кримський) і в підавстрійській Галичині (І. Франко, У. Кравченко, В. Пачовський, Б. Лепкий, О. Луцький). У такий спосіб вони утверджували та пропагували не лише українську музику, але й українське слово, пробуджуючи своєю творчістю “виразний дух нації”.

Published: August 2021

Мета дослідження полягає у розкритті передумов становлення та розвитку дипломатичних систем і підготовки дипломатичних кадрів у державах Вишеградської четвірки (V 4) у 1991–2004 рр. Методологія дослідження. В основі методології дослідження лежать принципи історизму, об'єктивності, системності, науковості, а також використання загальнонаукових (аналіз, синтез, узагальнення) та спеціально-історичних (історико-типологічний, історико-системний) методів. Наукова новизна полягає у тому, що вперше в українські та зарубіжній науці розглянуто передумови становлення дипломатичних систем та підготовки дипломатичних кадрів у державах V 4 (1991–2004 рр.) в органічній єдності, виокремлено групи зовнішніх та внутрішніх чинників, які впливали на ці процеси, проаналізовано особливості становлення та розвитку дипломатичних систем та підготовки відповідних фахівців у кожній з держав V 4. Висновки. Виокремлені чинники, які впливали на формування та розвиток дипломатичних систем та підготовку дипломатичних кадрів у державах V 4 (1991 – 2004 рр.), умовно згруповано в зовнішні  (макрочинники: розпад Радянського Союзу, падіння Берлінської стіни, крах комуністичного режиму, набуття незалежності та суверенітету Польщею, Чехословаччиною, Угорщиною, організація дипломатичних служб цих держав, зміцнення власного іміджу на міжнародному рівні, участь держав у міжнародних структурах, міжнародна політика, освітні ініціативи ЄС тощо) та внутрішні  (мезо- та мікрочинники: суспільно-політична ситуація в державах V 4, розвиток дипломатичної служби, зовнішньополітичний курс держави, офіційна політика Вишеграду та Болонська система, національна освітня політика кожної з держав, належна нормативно-законодавча база, розвиток вищої освіти у кожній з держав, освітні системи в  Радянському Союзі і в Україні, де теж готувалися кадри фахівців з міжнародних відносин, іншомовна освіта як пріоритетна державна політика тощо). Ці групи детермінант взаємопов’язані і творять складну систему, що програмувала створення дипломатичних служб, розвиток дипломатичної освіти у державах V 4.
НАЦІОНАЛЬНИЙ РОЗВИТОК УКРАЇНСТВА В ПУБЛІЦИСТИЧНІЙ СПАДЩИНІ СИМОНА ПЕТЛЮРИ 1902–1917 рр.
Authors: СЕМАШКО Ніна , БУЛИГІНА Олена
Published: August 2021

Мета дослідження – аналізуючи публіцистичну спадщину Симона Васильовича Петлюри 1902–19017 рр., дослідити його погляди на національне питання, а саме – визначити ключові фактори національного відродження українців, що перебували в полі зору діяча в період формування його суспільно-політичного світогляду. Методологія дослідження спирається на принципи історизму, об`єктивності, всебічності і цілісності, системності, а також на використання методів аналізу та синтезу, історико-порівняльного, історико-типологічного, проблемно-хронологічного. Наукова новизна полягає у комплексному висвітленні поглядів С. Петлюри на роль освіти, науки, культури, журналістики, книговидання у процесі національного розвитку українства, визначенні релігійної складової світогляду С. Петлюри періоду наростання українського руху на початку ХХ ст., кореляції соціал-демократичного та національного компонентів світоглядної парадигми діяча на етапі становлення його особистості. Висновки. Творча спадщина С. Петлюри демонструє багатовекторність його суспільних інтересів ще до початку Української національної революції 1917–1921 рр. Водночас національні питання домінують на сторінках ранніх публікацій С. Петлюри. Українська школа наука, література, театр, журналістика, книговидання покликані, на думку діяча, сприяти розвитку національної самоідентифікації українців, усвідомленню необхідності досягнення автономії України серед широких кіл українства, а також класовій боротьбі робітників і селян. Гуманітарна складова суспільного процесу, на думку С. Петлюри, мала бути соціально детермінована, відповідати потребам національного відродження українського народу та утвердженню соціалістичних ідеалів. С. Петлюра розглядав подальший національний розвиток українського народу крізь призму соціал-демократичних постулатів. Світогляду С. Петлюри зазначеного періоду притаманна також і релігійна складова, що не було характерно для українських соціалістів початку ХХ ст.
