Published: March 2021

The low interest of students in Indonesian language subject caused the majority of the students to be less enthusiastic about the lessons delivered by the teacher, so that studentsâ€™ learning outcomes were low. The purpose of this study was to increase studentsâ€™ interest and learning outcomes in Indonesian subjects through direct learning for 5th grade students in SDN 3 Karangraja. The subjects of this study were the fifth-grade students of SDN 3 Karangraja, with the total of 25 students. This research was conducted for two cycles. The results showed that in each cycle there was a progress that was proven with the result in the first cycle, the studentsâ€™ interest reached 13 students (52.00%) in learning and students who passed the learning through the improvement in cycle I were only 13 students (52.0%). In the second cycle improvement, there was an increase in interest of 23 students (92.00%). Thus, the learning outcomes of students were increasing with the number of 23 students (92.0%) passed the subject. This result proved that through the direct learning method students could solve their own problems in Indonesian language subject.

Published: March 2021

An urban forest is a collection of trees growing among buildings and people where they can protect the city as the functional traits. Forests are playing an important role in stabilizing CO2 concentrations in the atmosphere. As forest is a source of CO2 emissions, forests are also able to absorb and store CO2, so we could estimate the amount of CO2 absorbed by forest trees by calculating their biomass. This study aims to obtain the amount of carbon stock stored in the City Forest of Bumi Saniari, Teluk Bintuni Regency. Carbon stock was calculated to obtaine aboveground carbon (AGB), below ground carbon (BGB) and litter carbon (CS).  In this study no measurements were made of soil carbon. The method used in this research is descriptive method and field survey with measurements using the nondestructive method. The results obtained were 801.52 tons of stored carbon above ground (AGB), the soil surface / litter (CS) is 273.54 tons C. The total carbon stock is 10 hectares of 1,411.69 tons C.

NLRP12 is differentially expressed and up-regulated in the bone metastases of patients with metastatic breast cancer.
Authors: Mamoor Shahan
Published: March 2021

To understand the transcriptional nature of metastasis to disparate sites in human breast cancer, we mined published microarray data (1), comparing global gene expression profiles of metastasis to the bones and to the lymph nodes. We discovered that the nucleotide-binding oligomerization domain leucine-rich region (NLR) pyrin domain containing family protein NLRP12 was among the genes whose expression was most different, transcriptome-wide, in bone and lymph node metastases. NLRP12 mRNA was present at significantly higher quantities in metastasis to the bone as compared to metastasis to the lymph nodes. Analysis of patient survival data revealed that expression of NLRP12 in primary tumors of the breast was correlated with recurrence-free survival, in lymph node positive patients but not in lymph node negative patients. NLRP12 has functions in transcriptional regulation of immune gene expression (2, 3) and in pathogen recognition of Yersinia pestis (4).

Structural basis of anti-SARS-CoV-2 activity of hydroxychloroquine: specific binding to NTD/CTD and disruption of LLPS of N protein
Authors: Song Jianxing
Published: March 2021

SARS-CoV-2 is the coronavirus causing the catastrophic pandemic which already led to >120 millions of infections and >2.6 millions of deaths. Hydroxychloroquine (HCQ) has been shown to own promising potential in clinically combating SARS-CoV-2 but the underlying mechanisms still remain almost unknown. So far, all action sites are proposed on the host cells, and in particular no specific viral target protein has been experimentally identified. In this study, by use of DIC microscopy and NMR spectroscopy, for the first time we have decoded that HCQ specifically binds to both N-terminal domain (NTD) and C-terminal domain (CTD) of SARS-CoV-2 nucleocapsid (N) protein to inhibit their interactions with nucleic acids (NAs), as well as to disrupt its NA-induced liquid- liquid phase separation (LLPS) essential for the viral life cycle including the package of gRNA and N protein into new virions. These results suggest that HCQ may achieve its anti-SARS-CoV-2 activity by interfering in several key steps of the viral life cycle. The study not only provides a structural basis for the anti-SARS-CoV-2 activity of HCQ, but also indicates that SARS-CoV-2 N protein and its LLPS represent key targets for further optimization and development of anti-SARS-CoV-2 drugs.
FullControl GCode Designer: open-source software for unconstrained design in additive manufacturing
Authors: Gleadall Andy
Published: March 2021

A new concept is presented for the design of additive manufacturing procedures, which is implemented in open-source software called FullControl GCode Designer. In this new design approach, the user defines every segment of the print-path along with all printing parameters, which may be related to geometric and non-geometric factors, at all points along the print-path. Machine control code (GCode) is directly generated by the software, without the need for any programming skills and without using computer-aided design (CAD), STL-files or slicing software. Excel is used as the front end for the software, which is written in Visual Basic. Case studies are used to demonstrate the broad range of structures that can be designed using the software, including: precisely controlled specimens for printer calibration, parametric specimens for hardware characterisation utilising hundreds of unique parameter combinations, novel mathematically defined lattice structures, and previously inconceivable 3D geometries that are impossible for traditional slicing software to achieve. The FullControl design approach enables unconstrained freedom to create nonplanar 3D print-paths and break free from traditional restrictions of layerwise print-path planning. It also allows nozzle movements to be carefully designed - both during extrusion and while travelling between disconnected extrusion volumes - to overcome inherent limitations of the printing process or to improve capabilities for challenging materials. An industrial case study shows how explicit print-path design improved printer reliability, production time, and print quality for a production run of over 1,000 parts. FullControl GCode Designer offers a general framework for unconstrained design and is not limited to a particular type of structure or hardware; transferability to lasers and other manufacturing processes is discussed. Parametric design files use a few bytes or kilobytes of data to describe all details that are sent to the printer, which greatly improves shareability by eliminating any risk of errors being introduced during STL file conversion or due to different users having inconsistent slicer settings. Adjustable parameters allow GCode for revised designs to be produced instantly, instead of the laborious traditional routine using multiple software packages and file conversions. The FullControl design concept offers new opportunities for creative and high-precision use of additive manufacturing systems. It facilitates design for additive manufacturing (DfAM) at the smallest possible scale based on the fundamental nature of the process (i.e. assembly of individual extrusions). The software and source code are provided as supplementary data and ongoing updates to improve functionality and the user interface will be available at www.fullcontrolgcode.com.
The Covid-19 pandemic, political polarisation, climate change and the useless class: Why fostering wellbeing capacities should be part of the solution
Authors: Dorjee Dusana
Published: March 2021

Worsening of mental health and wellbeing has been symptomatic of a range of current societal crises - including the Covid-19 pandemic, political polarisation, climate change and the threat of useless class resulting from automation driven by fast artificial intelligence developments. The intertwined nature of these crises in terms of their causes and impacts on mental health and wellbeing is rarely acknowledge. This paper highlights the shared underlying sources of declines in mental health and wellbeing associated with these crises in terms of two wellbeing capacities – the self-regulatory capacity and the self-world capacity. Focus on these capacities can enable development and implementation of effective interventions and strategies across society which may significantly contribute to addressing the current mental health and wellbeing challenges associated with the societal crises.
Brexit, COVID-19 and Attitudes Towards Immigration in Britain
Authors: Pickup Mark , de Rooij Eline , Goodwin Matthew , van der Linden Clifton
Published: March 2021

A key issue in Britain’s referendum on European Union membership was the free movement of labour into Britain, with Brexit ‘Leavers’ having more negative attitudes towards immigrants compared to ‘Remainers’. Such anti-immigrant attitudes are driven by feelings of threat. As Brexit negotiations continued, the coronavirus pandemic presented a new threat, potentially heightening anti-immigrant attitudes. However, the prominent sacrifices of migrant workers in the fight against coronavirus suggests a potential for softening public attitudes. We ask: how did the COVID-19 pandemic, in the context of ongoing Brexit negotiations, affected anti-immigrant attitudes and how did these effects differ between Leavers and Remainers? Through a survey experiment, we test the effects of priming COVID-19 thoughts, showing that COVID-19 may exacerbate anti-immigrant attitudes among Leavers while having little effect on Remainers. In doing so, we explore the effect of a viral threat on immigration attitudes and heterogeneity in that effect, based on political identities.
Learning it the hard way – how enjoying life and positive appraisal buffer the negative effects of stressors on mental health in the COVID-19 pandemic
Authors: Daniels Anna , Wellan Sarah Aline , Walter Henrik
Published: March 2021

Background. Higher levels of stress and negative emotions such as anxiety and depression have been reported since the beginning of the COVID-19 pandemic, but it remains less clear how positive emotions, such as hedonic capacity, may be affected. Further, during lockdowns, the ability to learn new pleasurable activities (hedonic learning) may be particularly relevant. Here, we investigated if state hedonia and/or hedonic learning mediated the relationship between COVID-19 stress and mental health. Moreover, we explored whether positive appraisal style (PAS), a major resilience factor, influenced these relationships.Methods. Using a cross-sectional design, 5000 German-speaking participants filled out online questionnaires targeting stressors, mental health, state hedonia, hedonic learning, and PAS between April 9 and May 15, 2020. After confirming the factor structure of our constructs, we applied latent structural equation modeling to test mediation as well as moderated mediation models.Results. Stress showed a positive association with mental health symptoms, which was buffered by both state hedonia and hedonic learning. While higher stress was related to lower state hedonia, participants reported more hedonic learning with greater stressor load. The latter effect was greater for individuals with high PAS.Limitations. The present results should be replicated in longitudinal designs with representative samples to confirm the directionality and generalizability of effects.Conclusions. Both state hedonia and hedonic learning buffered the effect of stress on mental health in an early phase of the COVID-19 pandemic. Learning new rewarding activities in combination with a PAS may be especially relevant for maintaining mental health during lockdowns.
Anti-Asian Discrimination and Antiracist Bystander Behaviors amid the COVID-19 Outbreak
Authors: Lui P. Priscilla , Parikh Kish , Katedia Shefali , Jouriles Ernest
Published: March 2021

Anti-Asian racism is a public health concern, and it has escalated during the coronavirus disease 2019 (COVID-19) outbreak. Bystanders—individuals who directly witness or become aware of acts of racism—can help by discouraging perpetrations of discrimination (and other forms of violence), offering help and support to victims, and reinforcing antiracist prosocial norms. Yet, little is known about who engages in antiracist bystander interventions in response to discriminatory events, and who engages in proactive bystander behaviors to discourage future acts of racism. In the current study, 456 US community adults of diverse ethnoracial backgrounds (18-85 years, Mage = 48.8, 52.0% women, 212 Asian Americans) reported on their experiences with discrimination, attitudes about the acceptability of discrimination, and engagement in proactive and reactive bystander behaviors. About 40% of the Asian American participants experienced discrimination during a one-week period in early months of the COVID-19 pandemic. Among individuals who witnessed anti-Asian discrimination during the study period, 45% of them engaged in antiracist reactive bystander interventions. Controlling for ethnicity, gender, and attitudes about the acceptability of discrimination, individuals who reported more frequent experiences with everyday discrimination prior to the pandemic were more likely to engage in reactive bystander behaviors in response to anti-Asian discrimination. Lifetime experiences with discrimination may contribute to individuals’ active engagement in antiracist bystander behaviors. Future research directions on antiracist bystander actions and allyship are discussed.
What reduces prejudice in the real world? A meta-analysis of prejudice reduction field experiments
Authors: Hsieh  , Faulkner Nicholas , Wickes Rebecca
Published: March 2021

Despite advances to promote acceptance and equity in many countries, prejudice remains a significant social problem. Promoting intergroup harmony requires knowledge about what works to reduce prejudice in community settings. This meta-analysis of field experiments reveals the most effective intervention types and conditions for reducing negative attitudes towards minority groups in real-world settings. Across 69 intervention arms and 24,378 participants, results reveal that prejudice reduction interventions are effective at improving attitudes towards minority groups in real world settings (d = 0.51, 95% CI [0.33; 0.68]). Subgroup analyses indicate that less commonly explored approaches, such as perceived variability, may have larger effect sizes than contact-based interventions, but more research is needed to confirm the effects of these less-researched approaches. Additionally, results show that interventions are more effective for school and college cohorts than for adults, and that the effects of prejudice reduction interventions endure over time.
A Hierarchical Unequal-Variance Signal Detection Model for Binary Responses
Authors: Lages Martin
Published: March 2021

Gaussian signal detection models with equal variance are commonly used in simple yes-no detection and discrimination tasks whereas more flexible models with unequal variance require additional information. Here, a hierarchical Bayesian model with equal variance is extended to an unequal- variance model by exploiting variability of hit and false alarm rates in a random sample of participants. This hierarchical model is investigated analytically, in simulations and in applications to existing data sets. The results suggest that signal variance and other parameters can be accurately estimated if plausible assumptions are met. It is concluded that the model provides a promising alternative to the ubiquitous equal-variance model for binary data.

Personality and Peer Groups in Adolescence: Reciprocal Associations and Shared Genetic and Environmental Influences
Authors: Clark D. Angus , Durbin C. Emily , Heitzeg Mary M. , Iacono William G. , McGue Matt , Hicks Brian M.
Published: March 2021

Peer groups provide a critical developmental context in adolescence, and there are many well-documented associations between personality and peer behavior at this age. However, the precise nature and direction of these associations are difficult to determine as youth both select into and are influenced by their friends. We thus examined the phenotypic, genetic, and environmental links between antisocial and prosocial peer characteristics and several personality traits from middle childhood to late adolescence (ages 11, 14, and 17 years) in a longitudinal twin sample (N = 3762) using teacher ratings of personality, and self-reports of peer characteristics. At both within-person and between-person levels of analysis, less adaptive trait profiles (i.e., high negative emotionality, low conscientiousness, and low agreeableness) were associated with more antisocial and fewer prosocial peer characteristics. Associations between personality traits related to emotionality (negative emotionality and extraversion) and peer behavior were largely attributable to shared genetic influences, while associations between personality traits related to behavioral control (conscientiousness and agreeableness) and peer behavior were due to overlapping genetic and shared environmental influences. There was also some evidence for reciprocity and corresponsive processes such that traits in early adolescence contributed to selection into certain peer groups, which in turn extenuated those personality traits. Taken together, results suggest a set of environmental presses that push youth towards both behavioral undercontrol and antisocial peer affiliations, making the identification of such influences and their relative importance a critical avenue of future work.
Timbre-based machine learning of clustering Chinese and Western Hip Hop music
Authors: Bader Rolf , Zielke Axel , Franke Jonas
Published: March 2021

Chinese and Western Hip Hop musical pieces are clustered using timbre-based Music Information Retrieval (MIR) and machine learning (ML) algorithms. Psychoacoustically motivated algorithms extracting timbre features such as spectral centroid, roughness, sharpness, sound pressure level (SPL), flux, etc. were extracted form 38 contemporary Chinese and 38 Western 'classical' (USA, Germany, France, Great Britain) Hip Hop pieces. All features were integrated over the pieces with respect to mean and standard deviation. A Kohonen self-organizing map, as integrated in the Computational Music and Sound Archive (COMSAR\cite{COMSAR}) and apollon\cite{apollon} framework was used to train different combinations of feature vectors in their mean and standard deviation integrations. No mean was able to cluster the corpora. Still SPL standard deviation perfectly separated Chinese and Western pieces. Spectral flux, sharpness, and spread standard deviation created two sub-cluster within the Western corpus, where only Western pieces had strong values there. Spectral centroid std did sub-cluster the Chinese Hip Hop pieces, where again only Chinese pieces had strong values. These findings point to different production, composition, or mastering strategies. E.g. the clear SPL-caused clusters point to the loudness-war of contemporary mastering, using massive compression to achieve high perceived loudness.
Photography as a Reflection of the Photographer’s Pain in Time Stands Still
Authors: Almeshaal Madhawy Abdulaziz
Published: March 2021

The paper at hand attempts to interpret a female war journalist’s, the protagonist’s, Sarah Goodwin’s, decision to return to war zones after surviving a near-death experience in Time Stands Still, by Donald Margulies, (2010). The play starts with the protagonist’s strong assertion that she is endangering her life working in different war zones just to help the victims of wars by showing the world pictures of their suffering. After surviving a deadly road-bomb accident, Sarah Goodwin decided to settle down at home and never return to dangerous zones. However, after six months of recovery, this female war journalist decided to return to war zones. The present study finds it intriguing to speculate on Sarah Goodwin’s determination to return to such zones at such a time of her life. Through consulting some aspects of post-traumatic stress disorder (PTSD) and different aspects of Jacques Lacan’s words on photography, lack, and absence, the present study concludes that the protagonist’s desire to go back to war zones does not just help show the world pictures of wars victims’ suffering, but it helps the protagonist construct her own identity. Photography/war journalism becomes a medium through which Sarah Goodwin asserts her identity as a human being as she cannot fulfill her feminine role as a nurturer in a patriarchal society. The audience realizes that through photography, the protagonist projects her sense of lack and pain and attempts to attain some sense of wholeness.

Food and cooking methods are crucial in defining group identity and social relations and in examining the domestic economies. The Poster aims to study, from a functional and typological point of view, the fire installations and the contextual kitchen pottery in the Central Anatolia during the Late Bronze Age (1650-1200 B.C.). In particular, the archaeological contexts of the main Hittite sites of Anatolian Plateau, subjects of major interest in recent years, will be examined. The analysis and the comparison of the cooking tools (fireplaces, ovens, pots and baking plates) will allow to obtain some conclusions on the “Hittite Cuisine”, namely on the cooking techniques and the types of food consumed in the heart of Hittite kingdom. Archaeobotanical and archaeozoological data will also be integrated with the aim of a better comprehension of diets and cooking methods. In addition, some ethnographic observations will be discussed, in order to compare ancient and modern cooking practices in Anatolia.
Democratizing the Dramatic Text: Wannous’s Late Aesthetics and Individual Freedom
Authors: Zahrawi Samar
Published: March 2021

Sadallah Wannous (1941-1997), the Arab World’s most celebrated dramatist, gave up on the didactic art of the ‘theater of politicization’, in the middle of his career, in favor of a freer introspection of human psyche and passions. He spent his most prolific late years searching for new aesthetics and promoting a culture of free thinking. Abandoning his prior commitment to achieving the modern state, Arabic unity, the liberation of Palestine and the triumph of communism, he started creating individuals who are caught up in conflicting passions, loyalties and choices. However, his new themes will still betray a will to reform the many ailments in Arabic culture and politics, such as politico-religious coalitions and colonialism. This article will study the artistic and ideological transformation in Wannous’s later drama. It will also explore the later pro-democracy trends through analyzing the emerging individualism in characterization and the plurality of discourses in the plays of the later period 1989-1997, namely The Rape (1989), Historical Miniatures (1993), Miserable Dreams (1994), Rituals of Signs and Transformations (1994), and Drunken Days (1997).
Perplexity and Predicament: A Corpus Stylistic Analysis of A Summer Bird-Cage
Authors: Lin Xuqin
Published: March 2021

This paper aims to explore the text style of Margaret Drabble’s novel A Summer Bird-Cage. Specifically, it is intended to scrutinize how Drabble’s language style vivifies her representation of some women characters’ perplexity and predicament when they are confronted with problems related to value orientations and lifestyles. The present paper’s significance lies in a methodological breakthrough and resultant interdisciplinary insights. To achieve the main aims specified above, this paper will explore the following research question: stylistically, how some lexical categories such as nouns, verbs, and clusters are related to the spatio-temporal order of the novel and to its discourse prosodies or “tone of characters” speeches. As a whole, this study is situated in a research context where previous and many current studies of A Summer Bird-Cage are primarily qualitative. To complement them, this paper embodies mixed methods research, featuring in a computer-aided, data-based, corpus stylistic approach to the style in Drabble’s novel. Based on a multi-layered investigation of Drabble’s language use and a close corpus stylistic analysis of it, this paper obtains some interesting findings as follows. First, some young, educated British women’s complicated psychological experiences are thematized via narratorial introspection that centers around characters’ processing of mind. Second, the tone of the women characters’ speeches and the underlying attitude to some important issues are often negative, indicative of the women characters’ bewilderment. In short, this paper adopts a corpus stylistic approach to thematic studies and character analysis as a contribution to the body of specialized knowledge of Drabble’s art of fiction.
Textual Analysis of James Joyce’s Dubliners: A Fanonian Reading
Authors: Ferhi Samir
Published: March 2021

This research paper explores Joyce’s textual resistance to the Celtic Revivalism and the Irish Catholic conservatism in Dubliners (1914). Using postcolonial theories like the one proposed by Frantz Fanon in his The Wretched of the Earth (1968), the research shows that in writing Dubliners, Joyce, unlike the Irish Revivalist authors and conservative Catholics, was more interested in showing the imperial force or power in all shades, and put the blame on the lethargy of people when it needs to be placed, whether on imperial Britain, the Revivalist authors or the Irish Catholic conservatism. The paper also makes the case that if the colonial pathology of paralysis is the central theme of Joyce’s Dubliners, nevertheless, the power to resist or the resistance strain against this pathology is another essential idea explored by Joyce in his collection of short stories.
Translation of Idioms: How They are Reflected in Movie Subtitling

Idiomatic expressions are expressions with a figurative meaning different from their literal meaning, and therefore, they cannot be understood literally. This study aims to scrutinize some aspects of the translation of idiomatic expressions in a mystery movie entitled ‘Murder on the Orient Express’. Seventy-seven idiomatic expressions were found in the movie. The idioms can be categorized as follows: keywords with idiomatic uses (16) idioms with nouns and adjectives (2), idiomatic pairs (1), idioms with prepositions (7), phrasal verbs idioms (26), verbal idioms (5), idioms from special subjects (1), idioms with key words from special categories (16), and idioms with comparison (3). Phrasal verbs idiom was the most frequently occurred because idioms are mostly organized by verb comprising the combination of verb and preposition or verb and adverb. Further, the rendering of the idioms from English as the Source Language (SL) into Indonesian as the Target Language (TL) employed some strategies; translation by paraphrase was the highly frequent translation strategy. The strategy of using an idiom of similar meaning but dissimilar form was also located in the high-frequency position of the continuum. Furthermore, using an idiom of similar form and meaning and translation by omission were the translation strategies of low frequency. Translation by paraphrase was frequently used because the translator wanted to convey the meaning as clearly as possible while also considering the cultural difference between SL and TL. To sum up, the idiomatic expression dominantly used in the movie was phrasal verbs (34%), while the strategy that was mostly applied in translating them was translation by paraphrase (56%).
Implementation of Defense Policy Against Threats for Securing International Shipping Lanes in the Sunda Strait
Authors: Prakoso Lukman Yudho
Published: March 2021

The Sunda Strait is one of the areas in the Indonesian Archipelago Sea Channel (ALKI) I. The flow of this voyage is used for international interests. Facing the factual and potential threats that occur today, the Sunda Strait waters has an important role for international interest, particularly in Indonesia, since the position of its capital city is relatively close. This study is using a qualitative descriptive method of phenomenology and using the theory of George Edward III. The results of the study indicate that the variable communication between related entities shows that it still needs to be optimized since it is still not integrated. In the variable resources of each entity related to the security of the Sunda Strait are still have many limitations, particularly in budgetary resources that are related to the availability of other resources. The disposition variable is still found by persons related to the attitude of the executor who makes the obstacle an opportunity to do negative things, and in the variable structure of the bureaucracy, opportunities are still found to optimize the security of the international shipping channel in the Sunda Strait.
Reading F.S. Fitzgerald’s The Great Gatsby through Aristotle’s Eyes: Friendship, Gifts, and Commodities
Authors: Henna Ibrahim , Zerar Sabrina
Published: March 2021

This research explores the interlocked notions of friendship, community, gift, and commodity culture in Fitzgerald’s The Great Gatsby. It seeks to demonstrate that Fitzgerald’s ethical vision of friendship, community, the Bad, and the Good are deeply shaped by Aristotle’s works The Nicomachean Ethics, The Politics, and The Metaphysics. The extent to which Aristotle has shaped the form and contents of The Great Gatsby, a novel rightly described as a classic of its genre and how far the contentious aspect of its gendered and orientalized characterization can be traced to Fitzgerald’s dialogic relation with the Greek philosopher are among certain questions that this research addresses. The approach to the issue and the related questions stated above is eclectic. It draws its paradigms, partly from Bakhtin’s dialogical theory, partly from economic and cultural anthropology, and partly from postcolonial, historical theory of the type elaborated by Said and Fanon.

Authors: Dahami Yahya Saleh Hassan
Published: March 2021

Many central playwrights significantly contributed to the progress and advancement of Arabic drama. They were apt to achieve dramatic illustrations in several Arabic countries all the way through ages and places. Still, this study attempts to shed light on an innovator poet-dramatist who represents many cultures and experiences. It aims at displaying the most significant features of renovation associated with the development of the modern Arabic poetic drama that employs history and social problems to present a vision for Arabic literature in the contemporary age. The researcher adopts the critical-descriptive approach in analyzing the poet-dramatist, Ali Ahmad Ba-Kathir, and two of his poetic dramas. It is mapped with an introductory overview dealing with a concise notion of drama, concentrating predominantly on poetic drama. The foremost part copes with the developer and pioneer Ali Ahmad Ba-Kathir, focusing on his thoughts and experiences in the field. The paper, then, moves ahead to deal with two verse plays as a model of his craftsmanship and mastery. After that, the study finishes with a brief argument and/or recommendations and an end.

Authors: Románek Jaroslav , Palyzová Hana , Grygar Jan , Ernest Jan
Published: March 2021

Purpose: To assess the effect of intravitreal aflibercept on pigment epithelial detachment (PED) secondary to occult choroidal neovascularization (CNV) in treatment-naive patients.

Patients and methods: Retrospective analysis of thirty-six patients (thirty-eight eyes) with mean age 77 (SD ± 7), who were treated with aflibercept 2.0 mg (Eylea, Bayer) at the Department of Ophthalmology of 1st Faculty of Medicine of the Charles University and the Military University Hospital Prague. All patients were treated in fixed regimen, which means 3 loading doases 1 month apart, followed by further
2-monthly doses over total 12-month period. Best corrected visual acuity (BCVA) was evaluated on Early Treatment Diabetic Retinopathy Study (ETDRS) charts. Diameters as PED height, width and central retinal thickness (CRT) were assesed using spectral-domain optical coherence tomography. All previously mentioned were analyzed et the baseline and than at every visit. Therapy complications were also evaluated.

Results: Borderline significant improvement in the mean of BCVA score of 3.2 letters (SD ± 11.6, p = 0.05) at the end of follow-up period was observed. Mean PED height at 12 months significantly decreased by 140 µm (SD ± 238, p < 0.01). Reductions in PED height were correlated with reductions in central macular thickness (R = 0.94, p < 0.001) simultaneously with PED width (R = 0.45, p < 0.01). There was no significant correlation between PED height decrease and visual acuity. PED rupture was observed in 3 eyes (8 %).

Conclusion: Aflibercept intravitreal therapy in fixed regimen in patients with PED secondary to occult CNV shows great anatomical effect. However, correlation between PED diameters and visual acuity was not observed.
