Imaging in Heart Failure with Preserved Ejection Fraction: A Multimodality Imaging Point of View
Authors: Ünlü Serkan , Özden Özge , Çelik Ahmet
Published: April 2023

Heart failure with preserved ejection fraction (HFpEF) is an important global health problem. Despite increased prevalence due to improved diagnostic options, limited improvement has been achieved in cardiac outcomes. HFpEF is an extremely complex syndrome and multimodality imaging is important for diagnosis, identifying its different phenotypes and determining prognosis. Evaluation of left ventricular filling pressures using echocardiographic diastolic function parameters is the first step of imaging in clinical practice. The role of echocardiography is becoming more popular and with the recent developments in deformation imaging, cardiac MRI is extremely important as it can provide tissue characterisation, identify fibrosis and optimal volume measurements of cardiac chambers. Nuclear imaging methods can also be used in the diagnosis of specific diseases, such as cardiac amyloidosis.

Published: April 2023

Technological and procedural innovations presently permit the safe and effective performance of increasingly complex percutaneous coronary interventions, while new mechanical circulatory support devices offer circulatory and ventricular support to patients with severely reduced left ventricular systolic function and deranged cardiovascular hemodynamics. Together, these advances now permit the application of complex percutaneous coronary interventions to higher-risk patients who might otherwise be left untreated. Increasing observational data support the use of mechanical circulatory support in appropriate complex and high-risk patients as part of a larger multidisciplinary heart team treatment plan. In-progress and upcoming randomized clinical trials may provide higher-quality evidence to better guide management decisions in the near future.
COVID-19 Lockdown and Disney+ strategy on social networks on its launch during the State of alarm in Spain
Authors: Martín-Quevedo Juan , Fernández-Gómez Erika , Feijoo-Fernández Beatriz
Published: April 2023

The launch of Disney+ in Spain in March 2020 coincided with the Covid-19 pandemic and a period of home confinement for many Spaniards. This study examines the advertising and engagement strategy used by Disney+ on Twitter and Instagram, analyzing 2,268 messages. The platform’s social media use is similar to that of its competitors, with Twitter used for user engagement and Instagram used for content promotion. However, the study finds that the platform missed the opportunity to emphasize its unique qualities and appeal to the brand’s values. Despite this, Disney+ generated significant engagement during its launch month, reflecting high levels of user anticipation. Popular original productions such as The Mandalorian and Aladdin, as well as acquired content like The Simpsons, indicate the brand’s focus on a family or broad-spectrum target audience, in contrast to the younger and niche audiences favored by its competitors.
Las procesiones y su canto en la liturgia hispánica
Authors: Andrés-Fernández David , Gutiérrez Carmen-Julia , Hornby Emma , Rojo-Carrillo Raquel
Published: April 2023

Conocemos mucha información sobre las procesiones de la liturgia romana. Sin embargo, las procesiones del rito hispánico celebradas en la mayor parte de la Iberia cristiana antes de ca. 1080 apenas han sido estudiadas. Los manuscritos de la liturgia hispánica preservan rúbricas que muestran explícitamente las características y el contexto de dichas procesiones. Estas tenían lugar antes, durante o después la Misa (por ejemplo, en el Domingo de Ramos), al final del oficio vespertino o matutino (por ejemplo, en la consagración de una basílica), o incluso fuera de la rutina diaria de la liturgia (por ejemplo, en ocasiones votivas). En este artículo recopilamos la totalidad de las rúbricas que se transmiten en los manuscritos del rito hispánico y que informan sobre movimiento litúrgico. Algunas de estas rúbricas se refieren de forma inequívoca a procesiones, mientras que otras describen ceremonias que bien podrían ser descritas, más informalmente, como «liturgia en movimiento». En particular, nos hemos centrado en aquellas rúbricas procesionales, si bien hemos prestado también atención a otros movimientos como parte de la liturgia. Además, en este artículo identificamos los géneros de canto asociados con las procesiones y definimos las prácticas procesionales que atestiguan dichas rúbricas.
Where to Go to Get Unbiased Independent Advice on Pest Control in the UK in the 21st Century?
Authors: Dewar Alan M.
Published: April 2023

In the good old days (that is pre-Margaret Thatcher) agricultural research was conducted by various government funded research institutions. They provided a service to UK growers for which there was no charge. This advice was unbiased and supported by sound research. Then it was decided that this was a money making opportunity and charges were introduced. This led to much of this research being funded by the industry and out went the unbiased approach.
Kierunki badań nad kontraktem psychologicznym – systematyczny przegląd literatury
Authors: Bera Agata
Published: April 2023

Objective: The “psychological contract” used in the public sector is a relatively new research problem. The purpose of this article is to identify research trends and future directions for psychological contract research in the public sector.Research Design & Methods: A systematic literature review was conducted of 35 full-text peer- -reviewed research articles retrieved from Ebsco, Emelard, Proquest, Scopus, and Web of Science databases.Findings: The state of knowledge and directions for future research on psychological contracting in the public sector were identified using the analysis of the 35 articles.Implications / Recommendations: Past research on the psychological contract has focused on organisational commitment, organisational identification, trait- and assessment-oriented measurement of organisations, the dichotomous nature of the psychological contract, the psychological contract as a multifocal construct, the fact that the content of the psychological contract varies across cultures and societies, and the psychological contract versus affective organisational commitment. Future research could focus on examining the effects of the contract on the five major personality traits, the psychological contract in firefighting units, examining the effects of the psychological contracts on organisational identification, or understanding identification and de-identification with the organisation. This may prove useful for managers trying to predict whether employees will be willing to organise.Contribution: An analysis is the first of its kind of the available literature related to the psychological contract in public organisations.

Authors: Ok Minwook , Park Kyoungock , Kim Jiyeon ,   The Korean Society of Special Education
Published: April 2023

The purpose of this study is to explore special education teachers’ perceptions regarding the operation of an immersive content experience classroom, as well as suggest efficient operational plans based on the results. For this, focus group interviews were conducted with seven special education teachers who work in a special school with an immersive content experience classroom and are in charge of the classroom operation. Collected data was analyzed using a constant comparative analysis method. As a result, four categories, 10 themes, and 36 sub-themes were derived. The results of this study are as follows. First, use of the immersive content experience classroom is still at the beginner level; it is mainly used for interests or experience, rather than for educational purposes. Also, it was found that students’ level of intelligence and physical manipulation as well as teachers’ ability to use this classroom setting had a great influence on classroom usage. Second, the limitations of using immersive content experience classrooms includes a lack of teachers’ ability to use them, students’ difficulty using the programs, a lack of programs suitable for various requirements, and insufficient classroom usage in connection with curriculum. Third, the effects of using immersive content experience classrooms include increasing students’ interest and participation in learning, a reduction in students’ challenging behaviors, providing realistic experience opportunities that redeem disabilities or environmental limitations, and providing opportunities to experience new technologies according to societal change. Last, for successful use of the immersive content experience classroom, it is required to develop high quality and easy-to-use programs that meet the educational needs of students with disabilities; it is also crucial to strengthen teachers’ competencies for efficient use of immersive contents, continuous program updates and device repairs. Based on these results, the implications for effective operational plans for the immersive content experience classroom were discussed.

Öngörülemeyen potansiyeli ile çığır açan nanoteknoloji, iyi finanse edilen ve hızla yayılan bir disiplin olarak ortaya çıkmıştır. Nanoteknolojinin önemini kavramış gelişmiş ülkeler, bu alanda gayretlerini yoğunlaştırarak, bir yandan tahsis edilmiş büyük bütçelerle ulusal nanoteknoloji araştırma birimlerini kurmuşlar, diğer yandan eğitim gereksinimlerinin tespiti ve nitelikli personel yetiştirilmesi konularındaki eksikliklerini gidermek ve mevcut yapılarını iyileştirmek için harekete geçmişlerdir. Ayrıca, Devlet-Sanayi-Üniversite arasındaki sinerji artırılarak, nanoteknoloji alanında kümelenme sağlanmışlardır. Nanoteknolojiye bu kadar önem verilmesinin altında yatan temel etken, nano ölçekte olağan dışı fiziksel, kimyasal, biyolojik, optik, manyetik, mekanik ve elektriksel özelliklerin ortaya çıkmasıdır. Ayrıca nanoteknoloji, teknoloji yarışında geri kalan ülkeler için bir fırsattır. Gerekli önlemler alınırsa, uygun yapı ve etkili mekanizmalar oluşturulursa gelişmekte olan ülkelerin bu konuda iyi bir konuma sahip olabilmeleri mümkün görünmektedir. Bu çalışmada, çift kullanıma sahip nanoteknolojiye yönelik farkındalık sağlamak, bir önceki sanayi devrimine geç adapte olmuş ülkemizin aynı hatayı tekrarlamasını önlemek için gerekli uyarımları yapmak ve nanoteknolojinin sektörel uygulamarına yönelik öngörülede bulunmak amaçlanmıştır.

Authors: Cruz Paloma Soares Novello , Rocha Sheyla Ribeiro , Casalecchi Gabriel Avila , Germano Carla Maria Ramos
Published: April 2023

INTRODUÇÃO: A abordagem ao aprendizado pode ser influenciada por fatores individuais e ambientais.  O aprendizado profundo requer utilização de mecanismos cognitivos complexos e o envolvimento do estudante. OBJETIVO: Investigar a abordagem ao aprendizado de estudantes de graduação de cursos da área biológica e da saúde que utilizam metodologias tradicionais de ensino e sua percepção do ambiente educacional ao final da graduação. MÉTODO: Estudo transversal com estudantes de cursos da área biológica e da saúde de uma universidade pública. Dados coletados por meio de três questionários: sociodemográfico, o Questionário Revisado do Processo de Estudo (R-SPQ-2F) e Dundee Ready Education Environment Measure (DREEM). Para comparação de médias utilizou-se os testes t de Student ou Mann-Whitney. As correlações foram calculadas pelo Coeficiente de Spearman. A regressão linear múltipla foi utilizada para verificar a influência das variáveis na abordagem ao aprendizado. Análises estatísticas realizadas no programa SPSS (versão 26) e nível de significância de 5%. Para análises, estudantes divididos em dois grupos (cursos básicos e aplicados), considerando envolvimento em cuidados a saúde. RESULTADO: Os estudantes de ambos os grupos demonstraram utilizar mais a abordagem profunda do que a superficial (cursos básicos: 29,78 versus 22,00; aplicados: 30,16 versus 20,25), sem diferença significativa entre eles (p > 0,05).  Para cursos básicos, estar empregado exerceu efeito negativo sobre a aprendizagem profunda, enquanto, para cursos aplicados, realizar iniciação científica aumentou o uso dessa abordagem. A percepção geral do ambiente educacional foi considerada “mais positiva do que negativa” (cursos básicos: 104,28 e cursos aplicados 120,47), sendo que alunos de cursos aplicados tiveram percepção mais positiva do ambiente e aqueles com emprego fixo uma percepção mais negativa. CONCLUSÃO: O uso de abordagem profunda foi superior à da superficial para todos os cursos e houve associação positiva entre o uso de abordagens profundas e melhor percepção do ambiente educacional. Fatores sociodemográficos, como a necessidade de ter um emprego durante a graduação, podem influenciar a abordagem ao aprendizado, bem como a percepção do ambiente educacional.

Authors: Militaru Florentina Claudia , Militaru Valentin , Crisan Nicolae , Bocsan Ioana Corina , Udrea Anghel Adrian , Catana Andreea , Kutasi Eniko , Militaru Mariela Sanda
Published: April 2023

Prostate cancer is one of the most significant causes of morbidity and mortality in male patients. The incidence increases with age, and it is higher among African Americans. The occurrence of prostate cancer is associated with many risk factors, including genetic and hereditary predisposition. The most common genetic syndromes associated with prostate cancer risk are BRCA-associated hereditary breast and ovarian cancer (HBOC) and Lynch syndrome. Local-regional therapy, i.e., surgery is beneficial in early-stage prostate cancer management. Advanced and metastatic prostate cancers require systemic therapies, including hormonal inhibition, chemotherapy, and targeted agents. Most prostate cancers can be treated by targeting the androgen-receptor pathway and decreasing androgen production or binding to androgen receptors (AR). Castration-resistant prostate cancer (CRPC) usually involves the PI3K/AKT/mTOR pathway and requires targeted therapy. Specific molecular therapy can target mutated cell lines in which DNA defect repair is altered, caused by mutations of BRCA2, partner and localizer of BRCA2 (PALB2), and phosphatase and tensin homolog (PTEN) or the transmembrane protease serine 2-ERG (TMPRSS2-ERG) fusion. Most benefits were demonstrated in cyclin dependent-kinase 12 (CDK12) mutated cell lines when treated with anti-programmed cell death protein 1 (PD1) therapy. Therapies targeting p53 and AKT are the subject of ongoing clinical trials. Many genetic defects are listed as diagnostic, prognostic, and clinically actionable markers in prostate cancer. Androgen receptor splice variant 7 (AR-V7) is an important oncogenic driver and an early diagnostic and prognostic marker, as well as a therapeutic target in hormone-resistant CRPC. This review summarizes the pathophysiological mechanisms and available targeted therapies for prostate cancer.

Si vis pacem para bellum? Los totalitarismos y el Derecho
Authors: Franco-Chasán José
Published: April 2023

El presente artículo examina la relación entre la paz y la guerra. Esta última ha sido considerada como la forma fundamental de violencia y, por ende, ampliamente regulada por el derecho internacional público. Sin embargo, la guerra dista de ser la única amenaza que existe contra la paz. Existen otras muchas formas menos evidentes de atentar contra la misma, incluso a través del derecho positivo. El descuido de esos aspectos esenciales, sea de manera intencionada o por degradación, ha sido ampliamente utilizado por los regímenes más déspotas. Los totalitarismos han sabido instrumentalizar el Derecho en múltiples ocasiones. La estrecha relación entre la literatura y el Derecho permite identificar sus elementos clave y ofrece, asimismo, una propuesta para velar porque las sociedades no lleguen al estadio final de la ecuación: la guerra armada.

Por una parte, se propone estudiar dicho concepto en su evolución histórica y, por otra, se propone observarlo desde su contribución a la concreción del principio de culpabilidad penal. Se inicia con este trabajo una aproximación que trata de enriquecer la escasa atención que de forma unitaria y desde el amplio espectro que ofrece la Historia se ha concedido hasta ahora al más grave de los conceptos que conforma la culpabilidad: el dolo.
La emigración de retorno en España en los años veinte del siglo XXI
Authors: García Valverde María Dolores
Published: April 2023

La emigración de retorno es un tema nuevo, de los últimos años. Son pocos los trabajos que específicamente abordan el tema de las políticas de retorno de emigrantes españoles y la atracción del talento global en nuestro país. Y los que hay son recientes. No existen datos concluyentes del número de emigrados y retornados. Sin embargo, la situación existente en nuestro país y en Europa ha generado la inquietud por tratar el fenómeno del retorno de ciudadanos españoles y su tratamiento desde el punto de vista de los derechos sociales y laborales implicados. En el presente trabajo se pretende analizar y reflexionar sobre la situación de los trabajadores españoles que emigraron y después deciden retornar. En el análisis que se realiza ocupa especial atención la actual situación motivada por la crisis sanitaria (COVID-19). También son analizados los distintos Planes que se han ido aprobando por las Autoridades para el “fomento y el fácil regreso” de aquellos españoles que tienen pensado volver. Asimismo, se hace mención a los Planes de algunas Comunidades Autónomas.

Passenger car is one of the most preferable modes of transportation used in Malaysia. It is very important to keep safety features as suggested by ASEAN NCAP in a vehicle that we used in order to avoid and minimize the accident occurrence. However, new vehicle with advanced safety features is more expensive, where there are certain people that cannot afford to buy an expensive car such as B40 consumers (bottom 40% which household income is under RM3,860.00). According to the Maslow’s Hierarchy of Needs, the lower income group consumer will put the physiological need first rather than safety needs. As they cannot afford to buy a new car with extra safety features, they bought and old vehicle which currently has less safety features but with cost of maintenance were rather high. In this study – with regard to owning vehicles, specifically cars – the willingness to buy safer vehicle among lower group based on economic strength will be analyze.
Stability and Order in Europe Revisited: Lessons since 1945
Authors: Yazid Mohd Noor
Published: April 2023

This paper revisits the question of the international structure and political stability in Europe before and after 1945. It is argued that there were relations between the international political system and political stability in Europe during the two periods: the period from 1900 to 1945 and from 1945 to 1989. Instructive lessons from global political history and Mearsheimer's Neorealism have shown the instability of multipolarity in the present decline of the US order. This is because the international political structure strongly influenced the degree of stability in Europe. The different global political structure affected the different levels of stability before and after 1945. The bipolar structure strongly influenced and determined Europe's power configuration and stability after 1945. The instability of Europe before 1945 was strongly related to the multipolarity structure; there were many great powers, and the existence of multiple polarities with seven great powers posed difficulty in managing them. Thus, striking a balance between them was nearly impossible and was a lesson for today's reading of international politics.

Authors: Romanova N. I. , Zubatkina I.  S. , Ivanov P. I.
Published: April 2023

Background. Breast cancer contributed to 11.8 % of all the oncological diseases detected in Russia in 2020 and to 21.7 % of tumors detected among women. The frequency of brain metastases is estimated at 13–32 %. It is known that HER2 positive and triple negative breast cancers metastasize to the brain more frequently.

Aim. To present the case of stereotactic high‑dose irradiation for a large brainstem metastasis from HER2 positive breast cancer and re‑irradiation of the recurrence.

Materials and methods. Analysis of the results of stereotactic irradiation for a large brainstem metastasis from HER2 positive breast cancer and re‑irradiation of the recurrence with a local control over five years was performed.

Results. The local control after five years did not show any signs of tumor progression or post‑radiation necrosis. The patient’s Karnofsky Performance Status was estimated at 100 points.

Conclusions. The case shows the necessity of highly conformal stereotactic dose delivery to the tumor, precise determination of tumor boundaries on high resolution thin slice magnetic resonance imaging, verification of recurrence using metabolic studies and hypofractionated dose delivery. It remains open whether and to what extent target therapy may contribute to local control.

Authors: Galiullin Rustam R.
Published: April 2023

BACKGROUND: The Federal Scientific and Technical Program for the Development of Agriculture on 20172025 deals with the creation and implementation of competitive domestic technologies based on the scientific achievements. Therefore, the development and investigation of parallel driving systems for a machine-tractor unit with information and navigation equipment in the direction of increasing their accuracy of coordinates determination are relevant.

Development and research of the efficiency of a tractor transmission with a disc type gearbox
Authors: Polivaev Oleg I.
Published: April 2023

BACKGROUND: Modern tractors are equipped with gearboxes that are divided into three ranges, such as slow, operating and transport, for the sake of better power usage and fuel efficiency of the engine as well as getting higher performance. In addition, gearboxes must have a large number of gears, that leads to an increase in their mass and dimensions. An increasing mass of gearbox leads to additional high-quality metal consumption as well as energy costs for self-propelling of a tractor, which reduces its operational capabilities.
AIMS: Increasing the number of gears and reducing the weight of gearboxes for agricultural tractors.
METHODS: A disc-type gearbox (Patent RF No. 208805) has been developed to make it possible to increase the number of gears and reduce the weight of gearboxes for agricultural tractors. The feature of this gearbox is the gear disk with three gear rims on top and three on the bottom that is installed in its housing in addition to the usual gears and shafts. The implementation of the gear disk with gear rims makes it possible to reduce the number of gearwheels by more than half. The experimental gearbox is manual and interrupted-drive. It gives 18 forward gears and 18 reverse gears. Laboratory studies of a tractor with the experimental gearbox were carried out on a roller test bench. Load condition was arranged with the STEU-40 electric brake test rig in order to determine the transmission efficiency. During the testing, the torques on the gearbox input shaft and the tractor half shafts were measured. Reliability testing of the experimental gearbox, built in the LTZ-55 tractor, lasted for 2714 hours under the normal operation condition.
RESULTS: The results of the transmission efficiency study at the 1st, 5th and 10th gears with different drive wheels torques as well as different oil temperatures revealed that the transmission efficiency is in the range of 0.75-0.96 at the transmission oil temperature of 16 to 60C, which corresponds to the numerical values of fixed-ratio transmissions of stock tractors. Operational tests of the tractor, equipped with the experimental gearbox, showed efficiency of gearbox during operation of 2714 hours.
CONCLUSIONS: Laboratory studies of the LTZ-55 tractor, equipped with the experimental gearbox (Patent No. 208805), showed that the transmission efficiency improves with an increase in the drive wheels torque and the transmission oil temperature, and deteriorates with an increase in the gear number. The efficiency of the experimental transmission is in the range from 0.75 to 0.96, which corresponds to stock manual interrupted-drive transmissions of tractors. With an increase in oil temperature up to 60 C, the efficiency of the transmission greatens.

Authors: Gorobey Vasily P. , Moskalevich Vadim Yu. , Godzhaev Zakhid A.
Published: April 2023

BACKGROUND: The study is focused on improvement of basic machines and development of new machines for digging of holes for young fruit trees in firm soils.
AIMS: Expansion of technological abilities and decrease of energy resource intensity of an earth auger with the rotary working body for the sake of replacement of technically obsolete pothole diggers.
METHODS: For working bodies parameters substantiation, the vineyard rotary earth auger, which design includes a bulk, a frame, a rod and a beam, forming the hinged forebody mechanism, whereas the bulk and the frame are linked to the attachment system of the power source, is investigated.
RESULTS: The most widespread actuators of working bodies of universal hole diggers are analyzed. Principles of shock-and-vibrational digging of a drill tool make it possible to obtain significant improvement of digging performance. The design and technological layout of an earth auger and the theoretical substantiation of working bodies parameters under the vibration effect are proposed. The amplitude of the bar reciprocating motion along the splines is not less than washer teeth height in order to transform the rotation into the reciprocating motion in the vibrational operation mode of an auger. For the vibrational operation mode of an earth auger, the simulation model, considering physical and mechanical properties of soils, geometry parameters of the working body for the sake of substantiation the number of teeth of working body drive washers are proposed. It is found that for the auger diameter increases from 0.15 to 0.35 m the number of teeth of working body vibratory drive washers, ensuring demanded vibration frequency for soil layer breaking-off by auger shares, increase from 7 to 16 pieces in accordance to technical properties of the auger and physical and mechanical properties of considered firm soils. The proposed design parameters for reducing gear box fixed to the frame and auger offset from the tractor longitudinal axis corresponding to frame rotation angle = 3320 is ensured by a hydraulic cylinder, the beam length L1 is 800 mm, for pivot fixing of the frame with the length L2 of 1300 mm, the offset value up to 1500 mm.
CONCLUSIONS: The obtained results of the earth auger simulation for operation at firm soils in the case of planting perennials are given. The study is targeted to the expansion of technological abilities, the substantiation of design and technological parameters of an earth auger and the decrease of energy resource intensity of hole digging.

Authors: Vasilev Yuriy A. , Grik Evgeniia A. , Panina Olga Yu. , Khoruzhaya Anna N. , Semenov Dmitriy S. , Bazhin Alexander V. , Vasileva Yulia N.
Published: April 2023

Extensive spread of the coronavirus disease (COVID-19) prompted an investigation of its diagnostic features. Acute viral pneumonia associated with COVID-19 has been described in detail using CT, radiography, and MRI. There is no data in the literature on the descriptive picture observed with dynamic MRI. Considering a comprehensive diagnostic approach, radiologists should know how to correctly recognize and interpret COVID-19 on MRI. This case series demonstrated the ability of dynamic MRI to detect the cloudy sky sign and distinguish it from consolidation in COVID-19 patients, thus presumably distinguishing between early or mild changes and a progressive clinical course. These changes in dynamic lung images on MRI can be recorded depending on the phase of the respiratory cycle. Thus, MRI, as a radiation-free tool that can be used to examine a patient with acute viral pneumonia COVID-19, can be useful in cases where access to computed tomography is limited and dynamic morphofunctional imaging is required.
Impact of Site-Response Characterization on Probabilistic Seismic Hazard in the Po Plain (Italy)
Authors: Mascandola Claudia , Barani Simone , Albarello Dario
Published: April 2023

We present a probabilistic seismic hazard analysis (PSHA) for the entire Po Plain sedimentary basin (Italy)—one of the widest Quaternary alluvial basins of Europe, to evaluate the impact of site-response characterization on hazard estimates. A large-scale application of approach 3 of the U.S. Nuclear Regulatory Commission (NRC) to include seismic amplification in the hazard is presented. Both 1D amplification related to stratigraphic conditions and 3D amplification due to basin effects are considered with the associated uncertainties, and their impact on the hazard is analyzed through a sensitivity analysis. Whereas 3D basin effects are considered through the application of an empirical, spatial invariant correction term, 1D amplification was estimated throughout the study area by means of dynamic (equivalent linear) ground-response analysis. To separate aleatory variabilities and epistemic uncertainties related to site response, a partially nonergodic approach is used. The results provide a finer picture of the actual seismic hazard, highlighting those areas where the ground motion is affected by amplification effects due to local or regional geological features. We found that, for a return period of 475 yr, neglecting basin effects produces a 30% underestimation of the seismic hazard in the long-period (>1 s) range. Moreover, with reference to the hazard model adopted, such effects are responsible for most of the epistemic uncertainty (up to 80%) in the results. Therefore, such effects deserve special attention in future research related to PSHA in the Po Plain sedimentary basin.

ÖZ
Gündelik yaşamın her alanında karşılaştığımız ve toplumsal anlamda birlikteliği zedeleyen bir sorun olarak nefret söylemi, sadece yüz yüze değil teknolojik gelişmeler ile birlikte tüm yeni medya mecralarında karşımıza çıkmaktadır. Çağımızın en çok kullanıcıya sahip olan eğlence alanlarından birisi dijital oyun sektöründe dahil bu söylemlerle sık sık karşılaşılmaktadır. Özellikle dijital oyun reklamlarının yayınlandığı video paylaşım platformlarında bu söylemlere sık sık rastlanılmaktadır. Bu çalışmanın amacı reklamlar üzerinden bir çevrimiçi video paylaşım sitesi aracılığıyla tüketicilerin ürettikleri nefret söylemleri ve ne gibi söylemlerin ön plana çıktığını ortaya koymaktır. Çalışma nitel bir çalışma olup kullanıcıların reklamlara yaptıkları yorumları Teun A. Van Dijk’in eleştirel söylem analizi yöntemi ile analiz edilmiştir. Youtube video paylaşım platformu üzerinden en fazla görüntülenme, beğenmeme ve kötü yorum alan oyun reklamları araştırma evrenine dâhil edilmiştir. Bu reklamlar içerisinden en fazla olumsuz yorum ve beğenmeme sayısı alan 4 farklı türden oyun reklamı örneklem olarak seçilmiştir. Çalışmada MAXQDA programı kullanılarak Youtube üzerinden reklam yorumları ve beğenmeme sayısı çekilmiştir. Çevrimiçi video paylaşım sitelerinde nefret söyleminin çok yaygın bir şekilde kullanıldığı ve reklam aracılığıyla oyuna veya firmaya olan nefretin yansıtıldığı bulgusuna ulaşılmış ve bunun sonucunda kullanıcılar tarafından yapılan kötü yorumlar çerçevesinde, toplumun ve internet kullanıcılarının bilinçlendirilmesi ve bu çerçevede tüm internet kullanıcılarına yeni medya okuryazarlığı eğitiminin verilmesi gerektiği sonucuna varılmıştır.

Любое событие окружающей действительности находит свое отражение в  человеческой речи. Выбор лексико-семантических средств помогает выразить отношение говорящего к  событию. Благодаря уникальным семантическим свойствам глагол раскрывает разнообразные аспекты действия: его тип, способ, инструмент, объект. Анализируются способы оценочной интерпретации события акциональными глаголами со значением уничтожения и  разрушения одушевленного объекта. Среди основных компонентов оценочной интерпретации события уничтожения рассматриваются объект уничтожения и его количественные характеристики, способ, интенсивность действия, цель, инструмент уничтожения. Представлены примеры употребления акциональных глаголов со значением уничтожения и разрушения одушевленного объекта в современном английском языке.

All events of the world around us are reflected in human speech. The choice of lexical and semantic means helps the speaker to express his attitude to the event. Due to unique semantic properties, a verb reveals various aspects of the action – its type, method, instrument (tool), object. The article analyzes the ways of evaluative interpretation of the event by actional verbs with the meaning of destruction of an animate object. The main components of the evaluation interpretation of the destruction event are the object of destruction and its quantitative characteristics, method, intensity of the action, purpose, and instrument (tool) of destruction. The article presents examples of the use of actional verbs with the meaning of destruction of an animate object in the modern English language.
