Published: October 2019

Six potential peptidomimetics of the cross-reactive neutralizing anti-HIV-1 antibody N6 that are able to mimic the pharmacophoric features of this immunoglobulin by specific and effective interactions with the CD4-binding site of the viral gp120 protein were identified by virtual screening and molecular modeling. The key role in the interaction of these compounds with gp120 is shown to play multiple van der Waals contacts with conserved residues of the gp120 Phe-43 cavity critical for the HIV binding to cellular receptor CD4, as well as hydrogen bond with Asp-368gp120 that increase the chemical affinity without activating unwanted allosteric effect. According to the data of molecular dynamics, the complexes of the identified ligands with gp120 are energetically stable and show the lower values of binding free energy compared with the HIV-1 inhibitors NBD-11021 and DMJ-II-121 used in the calculations as a positive control. Based on the data obtained, it was concluded that the identified compounds may be considered as promising candidates for detailed experimental studies to their further use in the design of novel antiviral drugs presenting HIV-1 inhibitors that block the early stages of the development of HIV infection.
Discursos desde los Márgenes: Mujer y Arte de Acción en la Galicia Contemporánea
Authors: Tejo Veloso Carlos
Published: October 2019

This article presents an analysis of contemporary performance art carried out by women in Galicia; a complex issue if we consider that the nature of the discipline is a practically unexplored matter. Our reflection begins by defining the typology and particularities of Galician performance art. After that, we address the performance art context in Galicia and, finally, we examine the production of three artists that we consider essential: María Marticorena, Ana Gesto and María Roja. Our methodology emerges from a thorough search of available bibliographic resources, updated fieldwork through interviews, and tracking of photographic and videographic documentation. We have opted for a qualitative interview, focused on the artists analysed in the article which can be consulted as "Annex I", attached at the end of the text. This article unveils performance art that starts in the second half of the first decade of the new century, with the almost exclusive presence of women developing heterogeneous themes but influenced by the Galician cultural context. They haven’t had institutional support or been part of self-management movements, so frequent in other parts of Spain.
An Early Iron Age Foundry at Kargat-4, Southwestern Siberia
Authors: Durakov I. A. , Kobeleva L. S.
Published: October 2019

During the excavations at an Early Iron Age site of Kargat-4 in central Baraba, a foundry was discovered. The complex consisted of a melting furnace in the center of the structure and several utility pits. We give a detailed description of these features, the associated artifacts, and the archaeological context. Among the items from the infi ll are fragments of at least fi ve clay molds, three crucibles, drops of spilt bronze, a fragment of a spout, and bronze tongs. The casting kit included three stone utensils—two whetstones and a hammer. All the molds were destined for casting celts. The best preserved one had two valves, which were found inside a dwelling in a utility pit at the entrance and outside it. For each artifact, a detailed description, results of the analysis, and parallels are provided. Techniques of manufacturing molds and crucibles, such as those found at the site, are reconstructed. They are shown to have originated in areas situated west or southwest of Kargat-4. During the Early Scythian age they were practiced in northern Kazakhstan and eastern Urals, and they were apparently introduced to central Baraba by people associated with the Bolshaya Rechka culture during the Bronze to Iron Age transition, as evidenced by the Berlik and Krasnoye Ozero cultures.
Evidence Relating to the Christian Missions in the Trans-Urals and Northwestern Siberia (8th to 16th centuries)
Authors: Baulo A. V.
Published: October 2019

This study addresses the possible activity of early Christian missions among the Vogul (Mansi) of the Urals, Trans-Urals, and northwestern Siberia between the 8th–16th centuries. Three stages in their history are described. The fi rst (700–1000 AD) was marked by the import of southwestern Central Asian silver dishes (diskoi) reproducing biblical themes and Christian symbols. Specimens from Grigorovskoye, Anikovskoye, and from the Malaya Ob had been cast in Nestorian communities of Semirechye. The imported diskoi gave rise to the tradition of offering food to deities on metal dishes. The second stage (1200–1400 AD) began when silver plaques depicting the famous theme of icon painting (“The feat of the Martyr Demetrius of Solun defeating King Kaloyan of Bulgaria”) had been imported to the region. The third stage (15th and 16th centuries) correlates with the Russian expansion to Siberia and attempts to baptize the natives. At the ceremony, baptismal symbols such as tin plaques were given to the neophytes. Apparently, most plaques represent the biblical King David and were manufactured by Russians in the late 1400s to early 1500s. In the 16th century, plaques with the fi gure of St. George appeared in Siberia. The analysis of items showing biblical and hagiographical characters and of their distribution in northwestern Siberia suggests that Christian missions were unable to oust paganism from the region. Russian religious items were used in native rituals mostly if they represented horsemen, because these seemed to allude to the son of the Ob Ugric supreme deity Mir-Susne-Khum, also depicted as a horseman.

the 18th-century expeditions from the Academy of Sciences aimed at colonizing new territories, especially eastern, exploring their landscapes, natural resources, and inhabitants. The article focuses on the team working in the Cheremshan basin. The description of findings is arranged in five sections, following Lepyokhin’s classification: landscape, population, clothing, occupations, and rituals. For the first time, a complete, updated, and verified list of settlements visited by the expedition members is provided. The role of the Imperial St. Petersburg Academy of Sciences Director, Count Vladimir Orlov, in the organization of the expedition is described. The author disproves the opinion regarding the authorship of the anonymous article “Brief News About Simbirsk Vicegerency” published in the “Mesyatsoslov” journal in 1786. The persons to whom the article was attributed include Lepyokhin, Maslenitsky, and Ozeretskovsky, but the textological analysis of the article and of the manuscript at the Russian State Archives of Military History suggests that this is a collective digest of manuscripts by Milkovich and Maslenitsky.

Published: October 2019

Aim: to analyze the data obtained from using of intraocular lenses — the hydrophobic IOL Citrin and a hydrophilic IOL Aquamarine, produced by Russian company — NanOptic. Materials and methods. A total of 56 IOLs, produced by NanOptic (38 hydrophobic IOLs Citrine and 18 hydrophilic IOLs Aquamarine) were implanted. The observation period was from 3 to 12 months. The indication for phacoemulsification was age cataract. The age of the patients was 54–85. Patients before the operation were conducted basic studies. The mean uncorrected visual acuity before the operation was (UCVA) 0.121 ± 0.120 (0.001–0.3), and the mean corrected visual acuity was (BCVA) 0.187 ± 0.140 (0.001–0.6). All patients underwent standard phacoemulsification. Results. The early postoperative period was without any complications. In the postoperative period the mean UCVA in patients with “Citrine” and “Aquamarine” was 0.90 ± 0.10 (0.7–1.0) and 0.96 ± 0.07 (0.8–1.0) accordingly, and the mean BCVA was 0.94 ± 0.07 (0.8–1.0) and 0.99 ± 0.02 (0.9–1.0) accordingly. In all cases, the refraction obtained was consistent with the prediction. The error in IOL calculation was minimal and permissible. There weren’t any case of secondary cataract in patients with hydrophobic IOLs, and 3 cases of lens posterior capsule fibrosis of 1 degree in patients with hydrophilic IOLs in 3–12 months observation. The position of IOL in capsule bag was stable. Conclusions. The results of implantation of new Russian-made IOLs on the given parameters appeared to be satisfactory, that allows to recommend them for implantation in cataract surgery.

Modern human life conditions are associated with the increase of visual load in the volume and intensity. It determines the social and scientific significance of the study of the visual system functional capabilities with refractive errors. Due to peculiarities such types of ametropia as hypermetropia, hypermetropic and mixed astigmatism are the cause of inadequate load on the visual analyzer. Foreign and Russian scientists mainly pay attention to the study of these functions in childhood, adolescence or presbyopic age. We studied the frequency and degree of binocular and accommodative disorders in adult patients (18–48 years) with hypermetropia, complex hypermetropic and mixed astigmatism. Depending on the type of ametropia, the patients were divided into 2 groups. Group I Hm ast included 58 patients with hypermetropia and complex hypermetropic astigmatism, group II Mixed ast — 60 patients with mixed astigmatism. Patients were divided into two subgroups depending on age: subgroup A included patients aged 18–34 years, subgroup B — patients aged 35–48 years. The control group was 50 persons with emmetropic refraction, which were also divided according to age into two subgroups. In the course of the study, there were noted violations of the accommodative, binocular, oculomotor functions in various combinations of one or several parameters in adult patients with hyperopia, complex hyperopic astigmatism, mixed astigmatism in 10–32 % of cases. A significant percentage of detected latent sensory-motor disorders determines the need for a detailed study of these functions to choose the optimal correction method.

Published: October 2019

Increased intraocular pressure (IOP) is the main risk factor for the development of primary open-angle glaucoma (POAG). Nowadays medicine that reduce IOP remain the main method of treating for POAG. The first-line drugs for POAG are prostaglandin analogues. In Russia, for the first time, it appeared not in the form of a fixed combination (Bimoptic). In this regard it is very important to evaluate the clinical efficacy and safety of Bimoptic as a monotherapy and additive component in the treatment of patients with POAG. Patients and methods. Patients were divided into 3 groups depending on the treatment. Group I comprised of 34 patients with newly diagnosed glaucoma on monotherapy with bimatoprost 0.03 %. Group II consisted of 30 patients who started taking bimatoprost 0.03 % as a replacement for latanoprost 0.005 % or travoprost 0.004 %. There were 32 patients in group III, who were prescribed bimatoprost 0.03 % as an adjuvant therapy for B-blockers (BB) 0.5 % or carbonic anhydrase inhibitors (ICA) 2 %. Results. According to the results of the clinical study, it was found that instillation of Bimoptik as a monotherapy for newly diagnosed POAG leads to a decrease in IOP level by an average of 32.1 % of the initial level. With the additive tactics of assigning Bimoptik to the BB and / or IKA, the level of IOP goes down by 10.6 % more. If prostaglandin is changed to Bimoptik, the level of IOP decreases by 12.6 % of the prostaglandin-associated values. Also according to acquired data, Bimoptik has a low percentage of adverse reactions, slight hyperemia and discomfort were observed in 5.2 % of cases in all groups. Conclution. Bimoptik effectively reduces the level of IOP in both monotherapy and additive tactics with the least adverse reactions.

The environmental factors influence, quite often, negatively affects the state of health. Many of them, such as smoking, deterioration in ecology, uncontrolled alcohol intake, are in detail studied in terms of harm to a human body. Nevertheless, new technologies which action is insufficiently studied, are actively introduced into modern life. So, the use of cosmetology procedures can be a striking example. Now the prevalence of such procedures as eyelash extension, a permanent make-up a century, botulotoxin injections in a periorbital zone, assumes a wide scale. In foreign and domestic literature there are more and more messages about development of the complications which arose owing to use of the above-stated procedures. There are two clinical examples from our practice in this article. They demonstrate the complications which arose after holding a procedure of eyelash extension — acute toxic-allergic conjunctivitis and after a permanent make-up — a chemical burn of a cornea. In these clinical cases of a complication arose due to aggressive action of a chemical basis of the glue applied at eyelash extension and cream-anesthetic which is applied on eyelids before a permanent make-up a century. Treatment of patients included antiinflammatory, antihistaminic, antibacterial therapy and also a long course of the tear replacement therapy applied as keratoproteсtive therapy and for prevention of development of a dry eye syndrome. Considering scales of prevalence of cosmetology procedures in recent years, it is necessary to inform specialists and patients on potential risk of development of the complications connected with the above-stated procedures. The clinical examples given in the article and literature data, demonstrate that in case of cosmetology procedures complications it is necessary to carry out timely rendering the qualified medical ophthalmologic care. It is connected with the fact that, quite often, the cosmetology manipulations, even positioned as harmless, in particular, a permanent make-up of eyelid and eyelash extension can lead to heavy complications, up to vision loss.

A obesidade é definida pela Organização Mundial da Saúde (OMS) como uma doença caracterizada pelo acúmulo de gordura corporal, sendo de grande importância desenvolver pontos de corte baseado em indicadores antropométricos para o diagnóstico da obesidade como medida de prevenção e intervenção na saúde pública. Sendo assim, o objetivo do presente estudo verificou a relação dos indicadores antropométricos com a gordura corporal relativa em homens estudantes do curso de graduação em Educação Física da Universidade Federal do Amapá. Participaram deste estudo uma amostra de 22 homens (20 a 29 anos) aparentemente saudável. A seleção da amostragem foi feita por conglomerados, pois os voluntários foram selecionados aleatoriamente durante uma avaliação antropométrica para as medida da circunferência da cintura (CC), da circunferência do abdômen (CA), da circunferência do quadril (CQ), a razão cintura e quadril (RCQ) e do índice de massa corporal (IMC) e a gordura corporal relativa (GCR) pelo método por dobras cutâneas. O presente estudo demonstrou uma boa relação linear e significativa (r=0,50-0,75) entre os indicadores antropométricos e a GCR. Em conclusão, foram observadas correlações significantes entre todos os indicadores antropométricos e a GCR quando analisados em voluntários com características físicas e antropométricas similares às do presente estudo, tornando-se possíveis indicadores na predição de doenças e na promoção de saúde.

Published: October 2019

Sabe-se que o comportamento de pedestres em situações de emergência apresenta grande influência no tempo total de evacuação, tornando-o foco de muitas pesquisas no campo da física. Por outro lado, experimentos que reproduzam situações de pânico com seres humanos mostram-se impraticáveis devido a preocupações éticas e de segurança. Tem-se como objetivo, portanto, a simulação computacional de cinco diferentes cenários para uma sala de aula de 32 alunos, a fim de comparar os fluxos de pedestres quando da existência de uma ou duas saídas, além de duas disposições diferentes de mobiliário. Analisa-se ainda a correspondência dos resultados com uma situação real de evacuação registrada por câmera de vídeo e orientada pelo professor, descrita em Yang, Wu e Li (2011). As simulações foram realizadas em um software baseado em Forças Sociais e os resultados apontam a efetividade dos cenários com duas saídas, bem como a relevância do treinamento dos usuários.

The Need for Ability Grouping in English Classes in Public Schools in the UAE
Authors: Howling Christine
Published: October 2019

"Lack of English proficiency among secondary school graduates is a significant issue in the United Arab Emirates (UAE) as English is the medium of instruction in federal universities. Due to this, one-third of the UAE government’s university budget is spent on remedial courses that seek to develop the English-language skills of incoming university students (Salem & Swan, 2014).
This policy paper examines research conducted in 2014-2015 on the English language learning experiences of female students enrolled in the remedial Foundation program at a federal institute in Ras Al Khaimah, UAE. The results of the study indicate that the UAE’s current class grouping policy at the secondary school level disadvantages lower-performing students and needs to be reexamined. This paper recommends that the current policy be revised to group students in English classes according to their English-language abilities."

Understanding Inhibition of Steel Corrosion by Some Potent Triazole Derivatives of Pyrimidine through Density Functional Theory and Molecular Dynamics Simulation Studies
Authors: Bello Abdullahi , UZAİRU Adamu , SHALLANGWA Gideon Adamu
Published: October 2019

Density Functional Theory (DFT) calculation at B3LYP level of theory and 6-31G* basis set was applied on some triazole derivatives of pyrimidine which led to the optimization of their structures, generation of electronic and other important Quantum chemical descriptors such as the energy of the highest occupied molecular orbital (EHOMO), the energy of the lowest unoccupied molecular orbital (ELUMO), energy band gap (ΔE), Dipole Moment (μ), chemical hardness (η), chemical softness (σ), global electronegativity() and number of transferred electrons () using SPARTAN’14 Software. The obtained results shows a good correlation between the chemical structures of the inhibitors and their experimental inhibition efficiencies (%IEs). The ranking of these efficiencies (%IEs) nicely matched with the order of a good number of the generated descriptors but with a varying degree of correlation as majority of the descriptors indicates that I-4 is the best inhibitor among the data set. Furthermore, molecular dynamic (MD) simulations were carried out to search the best adsorption configuration of the inhibitor on the steel (1 1 0) surface using Material Studio 8.0. The obtained results of MD simulations suggest that the interaction was as a results of the chemical adsorption on the steel surface, since the binding energy > 100 Kcalmol-1 for all the inhibitors and the best adsorption energy was found to be -488.07 Kcalmol-1 (I-4). This observation are in good agreement with the DFT results and the experiment findings. Thus; this study provides a valuable approach and new direction to novel steel corrosion inhibitor discovery.
COMPARING PLEASURE AND PAIN: THE FUNDAMENTAL MATHEMATICAL EQUIVALENCE OF REWARD GAIN AND SHOCK REDUCTION UNDER VARIABLE INTERVAL SCHEDULES
Authors: Mallpress Dave E.W. , Fawcett Tim W. , McNamara John M. , Houston Alasdair I.
Published: October 2019

The relationship between positive and negative reinforcement and the symmetry of Thorndike's law of effect are unresolved issues in operant psychology. Here we show that, for a given pattern of responding on variable interval (VI) schedules with the same programmed rate of food rewards (positive reinforcement VI) or electric shocks (negative reinforcement VI), there is a fundamental mathematical equivalence between reward gain and shock reduction. We also provide the first normative account of how animals should respond on a negative VI schedule, showing that it is better to space responses evenly than to respond with a variable interresponse time (IRT). Published data from rats, however, indicate that these animals respond irregularly, often with a burst of activity immediately following a shock. While this is irrational in the experimental setting, it may represent an appropriate response to the heterogeneity of stimuli commonly encountered in natural environments. We discuss the broader implications of our analysis for understanding how animals evaluate appetitive and aversive stimuli.

Ruang kelas merupakan tempat terjadinya proses belajar mengajar bagi para siswa dan siswi. Didalam ruangan kelas dilengkapi dengan fasilitas-fasilitas pendukung yang memberikan rasa nyaman kepada siswa ketika belajar, selain fasilitas tersebut juga diperlukan fasilitas pendukung keselamatan. Dari hasil observasi dan wawancara bersama siswa sekolah dasar, tidak semua siswa menyadari pentingnya fasilitas tersebut, oleh sebab itu beberapa penelitian telah memberikan solusi yang mampu mencegah terjadinya kebakaran di ruangan kelas dan sosialisasi yang dilakukan ke sekolah-sekolah untuk menumbuhkan pola pikir anak sekolah terkait keselamatan. Selain upaya pencegahan juga diperlukan inovasi untuk membantu upaya penyelamatan apabila terdapat siswa yang terperangkap didalam kelas ketika terjadi kebakaran, adapun solusi yang diusulkan adalah Help Me, sebuah perangkat purwarupa yang mempergunakan sensor PIR yang mendeteksi gerakan dan mikrokontroller Arduino Uno sebagai pengolah informasi yang didapatkan dari sensor dan diteruskan ke buzzer. Dengan adanya bunyi buzzer  maka para tim penyelamat dapat mengetahui keberadaan korban dan bisa mempermudah mengevakuasi korban  kebakaran tersebut. Penelitian ini menggunakan design thinking dengan pola pendekatan Double Diamond yang diperkenalkan oleh British Design Council. Pendekatan ini bertujuan untuk menghasilkan inovasi teknologi yang merupakan solusi yang tepat terhadap permasalahan pengguna
Patchwork Gridshells: Using Modularity to Facilitate Prefabrication and Simplify Construction
Authors: Charest Philippe , Shepherd Paul , Harris Richard , Potvin André , Demers Claude , Ménard Sylvain
Published: October 2019

Modern architectural design has seen a shift towards iconic doubly-curved envelopes enclosing large column-free spaces. Gridshells have long been considered an efficient solution to such designs, but their actual use in practice has not spread worldwide. For elastic gridshells, their
advantages in terms of substantial material savings can often be overshadowed by the significant challenges associated with their construction. Similarly, for rigid gridshells, the manufacture of a large number of different members and nodal connections is often a barrier to their implementation.
This paper proposes an effective way of designing, fabricating and erecting gridshells. The "Patchwork Gridshell" consists of a number of efficient elastic gridshell patches assembled using rigid gridshell frames. It can easily generate a number of different configurations, use a wide range
of materials, and allows more architectural expression of practical long-span forms. The benefits of combining the ingenuously simple efficiency of elastic lattices and the power of digital fabrication are demonstrated by digitally rebuilding four alternative configurations of the Japan Pavilion
of the Hanover Expo 2000 as a case study. The result is a flexible digital workflow which creates large column-free spaces that are capable of being constructed efficiently by non- specialist contractors.
Comparison of Dynamic Analysis Methods in a Cable-Stayed Tower Under Extreme Wind Loads in Cuba

Several methods and investigations have been conducted in order to dynamically analyze the behavior of guyed mast telecommunication towers subject to wind loading, due to the importance of such structures in current society. Due to their slenderness, flexibility and lightweight, these
structures are particularly susceptible to wind loads, being strong hurricane winds the cause of several tower failures in Cuba. This works conducts the study of a 120 meters tall guyed mast, model MAR 2008, facing extreme wind loads in two different locations. The structure is modeled using
the computational assisted software SAP2000 and a dynamic analysis is undertaken using two methods: the equivalent static method "Patch Load" and the full dynamic method "Time History" using Direct Integration. The basic wind speeds are determined according to the Method of Independent Storms
(MIS) and standard turbulence intensities for cyclonés regions. Synthetic functions are generated for different heights of the tower in order to apply the "Time History" dynamic method. Finally, a comparison is established between the results in terms of axial loads, joint reactions
and displacements. The main conclusion of the study is that as the basic speed decreases, there is a higher resemblance in inner forces and displacements between the results obtained for the two studied methods.
Trace Elements of Cu-(Fe)-Sulphide Inclusions in Bronze Age Copper Slags from South Urals and Kazakhstan: Ore Sources and Alloying Additions
Authors: Artemyev Dmitry A. , Ankushev Maksim N.
Published: October 2019

In the paper, the results of an investigation into trace elements found in slag sulphides from 14 archaeological Bronze Age settlements of the Cis-Urals, Trans-Urals and North and Central Kazakhstan are presented. The study used Cu-(Fe)-sulphides as indicator minerals. Cu-(Fe)-S minerals in slags are primarily represented by covellite and chalcocite, as well as by rarer bornite and single chalcopyrite grains. Slag sulphides formed relic clasts and neogenic droplets of different shapes and sizes. Supergenic ores in the Bronze Age in Urals and Kazakhstan played a significant role in the mineralogical raw material base. In sulphides, the main indicator elements Fe, Co, Ni, As, Se, Te, Sb, Ag, Pb, and Bi are important markers of copper deposit types. Sulphides from olivine Cr-rich spinel containing slags of Ustye, Turganik, and Kuzminkovskoe 2 are characterised by As-Co-Ni assemblages and confined to copper deposits in ultramafic rocks. Olivine sulphide-containing slags from Kamenny Ambar, Konoplyanka and Sarlybay 3 are characterised by Co-Se-Te assemblage and confined to mafic rocks. Glassy sulphide-containing slags from Katzbakh 6, Turganik, Ordynsky Ovrag, Ivanovskoe, Tokskoe, Bulanovskoe 2, Pokrovskoe, Rodnikovoe, and Taldysay are characterised by Ag-Pb-(Ba)-(Bi) assemblage and confined to cupriferous sandstone deposits. High As, Sb, Sn and Ba contents found in slags can be seen as indicators of alloying or flux components in primary copper smelting. These include samples from Ustye, Katzbakh 6, Rodnikovoe, and Taldysay sites, where high Ba and As slag contents are identified. The compilation of a database with a broad sample of sulphide compositions from Bronze Age slags and mines in the Urals and Kazakhstan will permit the further identification of ore types and raw materials associated with a particular deposit.
Physical and Chemical Properties of the Slate Aggregate
Authors: Radanliev Petar
Published: October 2019

The slate aggregate has long been perceived as a substandard, low quality waste material with its physical and chemical properties not being competitive with those of the primary aggregates. It is assumed that the slate aggregate particles are not strong, that is not durable and will not compact. This research aims to address those claims and review the available literature on the performance of the slate aggregate. The review inaugurates by analysing the physical, chemical and mechanical properties of slate, before expanding into a literature review of laboratory testing’s on the effect of moisture content on density, compaction and layer thickness of slate aggregate.The paper reviews case studies of construction projects in North Wales, where the slate aggregate has been used for general fill and road building for many years. Some of the case studies include the A55 coastal road and duelling of the A5 in Anglesey (WRAP, 2004), where slate aggregate was successfully used as sub-base. The paper also investigates why many civil engineers are reluctant to use the slate aggregate and regard the material as sub-standard, flaky aggregate. The research paper reviews the potential usages and various products the slate aggregate is suitable for and satisfies the requested standards. The final topic reviewed is the cost of transporting slate aggregate compared with the cost of transport for primary aggregate and the introduction of the Primary Aggregates Tax (Parliament of the United Kingdom, 2011). The last topic includes a critical analyses of the claims that the slate aggregate a commercially viable construction material despite its remote location (Woodward et al, 2004). The transportation cost and the supply chain complexities must be evaluated prior to considering the long-term sustainability of the product (Radanliev et al1-6, 2014, 2015, 2016).
The Ambivalence of the Construction of Female Figure as a Hero in Barbie in Princess Power
Authors: Khoirun Nissa Zahra Zulfi
Published: October 2019

This research outlines the embodiment of the aspect of heroism and traditional femininity of a female figure in Barbie in Princess Power. The title of the movie undeniably raises a question on the conflicting image between masculine heroism and traditional femininity. Thus, this research aims to explore whether the movie embodies the aspect of heroism or perpetuates the traditional feminine figure. The finding reveals that women are constructed to glorify the femininity and to remain on the domestic sphere. Though the movie portrays some aspects of heroism which entails an active role in public sphere, the journey is diminished through the normalization of female figure in order to drag women into its natural sphere, to become a heroine.
