Authors: Zheng Qianmin
Published: March 2023

The purpose of the study is to find out the specifics of word formation in Chinese Russian-learners’ interlanguage. In the process of mastering a second language, interlanguage is considered as a language system in which exist its own rules and function, which differ from the rules of both the native and the target languages. The article updates the concepts of the term "interlanguage" in recent studies in Russian linguistics, discusses the common characteristics of interlanguage, analyzes speech features and written language materials related to interlanguage of two groups of Chinese philology students studying Russian language at the Faculty of Philology in Peoples' Friendship University of Russia. The novelty of the research lies in the fact that the author for the first time systematically described the specifics of word formation in Chinese Russian-learners’ interlanguage in aspects of prefix, suffix, word endings, etc., explained the reasons for their existence. The obtained research results provide useful recommendations to teachers working in the field of foreign language teaching; the results can be especially useful in classes for teaching Chinese students Russian language. The material of this article can also be used in the process of compiling textbooks and teaching aids on applied linguistics and the discipline of Russian language.

Authors: Derevskova Elena , Pozdniakova Natalia , Franchuk Oksana
Published: March 2023

Basing on their own experience in teaching linguistic disciplines, the authors of the article reveal the most complicated issues in Lexical semantics learning. Being involved into new system of education, the first and second-year students need not only to get new knowledge, but also to master skills of the research work by studying the term paradigm. The subject of the study is one of the possible methods of training, which allows forming the theoretical knowledge of students through practical skills. The authors believe that future linguists should have knowledge about the meaning side of the language units of different levels and be aware of the componential analysis of the words meaning. The authors technique is a system of creative research tasks designed to help students master important concepts of modern semantic research, form the ability to use the terms that make up the theoretical basis of the topic “Componential analysis of the lexical meaning of a word” correctly and consciously. At the first stage students individually need to determine the lexical meaning of the occasional word relying on the paradigmatic and syntagmatic links of the words (creative work is based on the novel by T. Tolstoy “Kys”). Then students form lexical meaning of the words of the same thematic group. At the final stage students write the dictionary entry. This technique not only helps students to understand fundamental concepts while studying “Componential analysis of the lexical meaning of a word”, but also make the results of the research work productive and the conclusions conscious.

Authors: Grevtsev Arsenii Vladimirovich
Published: March 2023

The subject of the work is the theses of the theology of personality. The aim of the study is to develop practical methods of pedagogy of professional counseling based on the provisions of the theology of personality. The work presents a number of theses of the theology of personality, synthesized on the basis of the works of the theologian and historian Vladimir Nikolaevich Lossky; describes principles of career guidance approaches; theoretical positions are combined into practical conclusions; a training case template and a template for working with it are compiled. The main provisions of the developed method are as follows: there cannot be one exact way to determine the interests of a person; the circle of specialties should not be limited by social factors; vocational guidance should be carried out in accordance with the ultimate goal of human activity — the perception of perfection; care should be taken to interpret the results of diagnostic tests/tasks that are not able to take into account all aspects of the uniqueness of the individual; professional guidance consultations should be carried out with a deep immersion in the understanding of the individual; through development in an area unfamiliar to a person, he can learn a new competence and show interest in it; through the self-giving of the individual in complete immersion in a cause that brings good to people, one can see the perfection of the individual. The method can be used in teaching various disciplines at different levels of education.

Authors: Villanueva Pablo , Baldoncini Matías , Forlizzi Valeria , Campero Alvaro , Rangel Carlos Castillo , Granja Jaime Ordóñez , Sufianov Albert , Lucifero Alice Giotta , Luzzi Sabino
Published: March 2023

Background:

Cisternostomy is a surgical technique thought of and developed as an option for severe brain trauma treatment. It demands a particular knowledge and skill to microsurgically approach basal cisterns and effectively manipulate their contents. To perform this procedure safely, the anatomy and pathophysiology must be clearly understood.

Methods:

Detailed microscopic dissection and anatomical review were done, after a detailed reading of facts and recent publications about cisternostomy. Cisternal pathways and landmark planning are described and augmented using a new method to show de arachnoid borders. Finally, a brief discussion is written as a synopsis.

Results:

Cisternostomy requires thorough microscopic knowledge and microsurgical skills. This paper intends to provide information to understand better the anatomy related, thus, easing the learning curve. The technique used to show arachnoid borders, complementing cadaveric and surgical images, was useful for this purpose.

Conclusion:

To perform this procedure safely, it is mandatory to handle microscopic details of cistern anatomy. Reaching a core cistern is necessary to assure effectiveness. This procedure needs, as well, surgical step-by-step landmark planning and performing. Cisternostomy could be a life-saving procedure and a new powerful tool for severe brain trauma treatment. Evidence is being collected to support its indications.
Pituitary hyperplasia resulting in visual deficit
Authors: Altaib Wail Salah , Dablouk Mohamed Osman , Jansen Michael , Khan Mohammed Habibullah , Kamel Mahmoud
Published: March 2023

Background:

Pituitary hyperplasia is an infrequent cause of visual disturbance and few such cases have been reported in the literature.

Case Description:

We describe the case of a 16-year-old female who presented with a short history of progressive headache and visual blurring. Examination revealed markedly constricted visual fields. Imaging revealed an enlarged pituitary gland. Hormonal panel was normal. Following endoscopic endonasal transsphenoidal biopsy and decompression of the optic apparatus, an immediate improvement in vision was noted. Final histopathological examination revealed pituitary hyperplasia.

Conclusion:

In patients with pituitary hyperplasia, visual deficit, and no identifiable reversible causes, surgical decompression can be considered to preserve vision.
Proper ophthalmic artery aneurysms
Authors: Hendrix Philipp , Bohan Christian , Dalal Shamsher Singh , Weiner Gregory M. , Kanmounye Ulrick S. , Schirmer Clemens M. , Goren Oded
Published: March 2023

Background:

The ophthalmic segment of the internal carotid artery (ICA) represents a common site for cerebral aneurysms. However, aneurysms of the ophthalmic artery (OphA) itself represent rare lesions and have been associated with trauma and flow-related lesions such as arteriovenous fistulas or malformations. Here, we explore clinical and radiological features of four patients managed for five proper ophthalmic artery aneurysms (POAAs).

Methods:

Patients undergoing diagnostic cerebral angiogram (DCA) between January 2018 and November 2021 with newly or previously identified POAA were retrospectively reviewed. Clinical and radiological data were analyzed to identify common and unique features.

Results:

Four patients with identification of five POAA were identified. Three patients suffered traumatic brain injury with subsequent identification of POAA on DCA. Patient 1 presented with a traumatic carotid-cavernous-sinus fistula requiring transvenous coil embolization and second stage flow diversion of the ICA. Patient 2 suffered a gunshot wound with ICA compromise, ethmoidal dural arteriovenous fistula (dAVF) development with rapid growth of two POAAs eventually requiring Onyx embolization. Patient 3 was assaulted and DCA showed a POAA without any other cerebrovascular pathology. Patient 4 had undergone N-butyl cyanoacrylate embolization of an ethmoidal dAVF 13 years ago with the feeding OphA carrying a large POAA. Re-DCADCA was performed for a newly developed and unrelated transverse-sigmoid-sinus dAVF.

Conclusion:

Management of POAAs poses a challenge to neurovascular surgeons since POAAs inherit a risk for visual deterioration or hemorrhage. DCA facilitates identification of coexisting cerebrovascular pathology. If clinically silent and not accompanied by cerebrovascular disease, observation appears reasonable.
Repeat discectomy for recurrent same level disc herniation: A literature review of the past 5 years
Authors: Musa Gerald , Barrientos Rossi E.C , Makirov Serik K. , Chmutin Gennady E. , Antonov Gennady I. , Kim Alexander V. , Otarov Olzhas
Published: March 2023

Background:

Recurrent disc herniations remain a challenge in spinal surgery. Although some authors recommend a repeat discectomy, others offer more invasive secondary fusions. Here, we reviewed the literature (2017–2022) regarding the safety/efficacy of treating recurrent disc herniations with repeated discectomy alone.

Methods:

Our literature search of recurrent lumbar disc herniations included; Medline, PubMed, Google scholar, and the Cochrane database. We focused on the types of discectomy performed, perioperative morbidity, costs, length of surgery, pain scores, and incidence of secondary dural tears.

Results:

We identified 769 cases that included 126 microdiscectomies, and 643 endoscopic discectomies. Rates of disc recurrence ranged from 1% to 25% with accompanying secondary durotomy varying from 2% to 15%. In addition, operative times were relatively short, ranging from 29.2 min to 125 min, with a relatively small average estimated blood loss (i.e., minimal to maximally 150 mls).

Conclusion:

Repeated discectomy was the most commonly performed treatment for same-level recurrent disc herniations. Despite minimal intraoperative blood loss and short operating times, there was a significant risk of durotomy. Notably, patients must be informed that more extensive bone removal for treating recurrent disc increases the risk for instability warranting subsequent fusion.
Late-onset aqueductal membranous occlusion treated neuroendoscopic procedure and consideration of its pathological findings: A case report
Authors: Nakamura Kazuki , Kuge Atsushi , Yamaki Tetsu , Shimokawa Yu , Tanaka Masahiro , Saito Shinjiro , Kondo Rei , Sonoda Yukihiko
Published: March 2023

Background:

Aqueduct of Sylvius stenosis/obstruction interferes with cerebrospinal fluid (CSF) flow and leads to the non-communicating hydrocephalus. Acquired non-neoplastic causes of aqueduct of Sylvius stenosis/ obstruction include simple stenosis, gliosis, slit-like stenosis, and septal formation, but the detailed mechanisms are not clear. In the present study, we experienced a case of late-onset aqueductal membranous occlusion (LAMO) successfully treated by neuroendoscopic procedure, which allowed us to examine the pathology of the membranous structures of the aqueduct of Sylvius occlusion.

Case Description:

A 66-year-old woman presented with gradually progressive gait disturbance, cognitive dysfunction, and urinary incontinenc. Brain magnetic resonance imaging (MRI) showed enlargement of the bilateral lateral ventricles and the third ventricle without dilatation of fourth ventricle, and heavily T2-weighted images showed an enlarged aqueduct of Sylvius and a membranous structure at its caudal end. Gadolinium contrast-enhanced T1-weighted images showed no neoplastic lesions. We diagnosed this case that the hydrocephalus due to late-onset idiopathic aqueductal stenosis or LAMO and the patient underwent endoscopic third ventriculostomy and endoscopic aqueduct oplasty. Membranous tissue specimens were obtained from the occluded aqueduct of Sylvius at the time of treatment. Histopathological examination revealed gliosis, and inside the gliosis, there were cell clusters that appeared to be ependymal cells and were corpora amylacea. We confirmed CSF flow at the site of obstruction of the aqueduct of Sylvius and the stoma of the third ventricle floor by MRI images. Her symptoms were improved immediately.

Conclusion:

We experienced a case of LAMO successfully treated by neuroendoscopic procedure, which allowed us to examine the pathology of the membranous structure of the aqueduct of Sylvius. The pathological study of LAMO is rare, and we report it, including a review of the literature.

Published: March 2023

Purpose: The aim of the study was to evaluate the changes that occur in parameters relating to muscle work and muscle hemodynamicsunder the influence of upright Lower Body Negative Pressure (LBNP) application during walking. Methods: 18 young females were included in this study. All 18 subjects participated in 2 trials of a 12-minute walking exercise on a treadmill equipped with a LBNP chamber, on a constant speed of 5 km/h. The first trial was executed under the application of a LBNP program (3 stages of -15, -25 and -30 mbar), while the second trial was similar, but without the activation of the negative pressure chamber. During both trials, the Vastus Lateralis (VL) muscle hemodynamic conditions were monitored continuously with a Functional Near-Infrared Spectroscopy (fNIRS) device and parallelly, VL activation was monitored via a Surface Electromyography (sEMG). Heart Rate (HR) values were recorded in the beginning and during the10th min of each trial, after which, the difference between the 2 values was calculated. Immediately after the conclusion of each trial, participants were asked to provide a score for perceived exertion using Borg CR-10 scale (10 for maximum exertion). Results: During the LBNP trial, Total Hemoglobin (tHb) and OxyHemoglobin (O2 Hb) concentrations in the Vastus Lateralis (VL), was significantly lower compared to the control (p=0.007, p=0.001), but with a significant increase rate in deoxy-hemoglobin (HHb) (p= 0.001). Tissue Saturation Index (TSI%) showed no significant alteration between trials (p= 0.668). All calculated parameters relating to work output showed a significant difference in the LBNP trial compared to control. HR was increased (p= 0.001), there were an increase in MPF and RMS amplitude in the VL (p=0.006, p < 0.001, respectively) and subjects reported higher rate of perceived exertion (p=0.001). Conclusions: The application of LBNP showed elevated work characteristics, mainly on the work output and less local muscle hemodynamics. This could be a time efficient training tool for stressing the musculoskeletal system, faster improve body composition and potentially enhancing cardio respiratory fitness.
Direct Light-Enabled Access to α-Boryl Radicals: Application in the Stereodivergent Synthesis of Allyl Boronic Esters
Authors: Marotta Alessandro , Fang Hao , Adams Callum E. , Sun Marcus Kailey , Daniliuc Constantin G. , Molloy John James
Published: March 2023

Operationally simple strategies to assemble boron containing organic frameworks are highly enabling in organic synthesis. While conventional retrosynthetic logic has engendered many platforms focusing on the direct formation of C–B bonds, α-boryl radicals have recently reemerged as versatile open-shell alternatives to access organoborons via adjacent C–C bond formation. Direct light-enabled α-activation is currently contingent on photo- or transition metal-catalysis activation to efficiently generate radical species. Here, we disclose a facile activation of α-halo boronic esters using only visible light and a simple Lewis base to enable homolytic scission. Intermolecular addition to styrenes facilitates the rapid construction of highly versatile E-allylic boronic esters. The simplicity of activation permits the strategic merger of this construct with selective energy transfer catalysis to enable the complimentary stereodivergent synthesis of Z-allylic boronic esters.
Room-temperature stacking disorder in layered covalent-organic frameworks from machine-learning force fields
Authors: Huang Ju , Shin Seung-Jae , Tolborg Kasper , Ganose Alex , Krenzer Gabriel , Walsh Aron
Published: March 2023

The local structures of layered covalent-organic frameworks (COFs) deviate from the average crystal structures assigned from X-ray diffraction experiments. For two prototype COFs of Tp-Azo and DAAQ-TFP, density functional theory calculations have shown that the eclipsed structure is not an energy minimum and that the internal energy is lowered for an inclined stacking arrangement. Here we explore the structural disorder of these frameworks at 300 K through molecular dynamics (MD) simulations using an on-the-fly machine learning force field (MLFF). We find that an initially eclipsed stacking mode spontaneously distorts to form a zigzag configuration that lowers the free energy of the crystal. The simulated diffraction patterns show good agreement with experimental observations. The dynamic disorder from the MLFF MD trajectories is found to persist in mesoscale MD simulations of 155 thousand atoms, giving further confidence in our conclusions. Our simulations show that the stacking behaviour of layered COFs is more complicated than previously understood.
Alginate/Xanthan gum hydrogels as forensic blood substitutes for bloodstain formation and analysis.
Authors: Orr Amanda , Wilson Paul , Stotesbury Theresa
Published: March 2023

Understanding the behaviour of human blood outside of the body has important implications in forensic research, especially related to bloodstain pattern analysis (BPA). The design of forensic blood substitutes (FBSs) can provide many advantages, including the incorporation of multiple physiological components for use as safe and reliable materials for forensic applications. In this work, we present the design of synthetic alginate and xanthan gum-based hydrogels that contain electrosprayed microparticles (MPs) with and without crosslinked DNA. In addition to the MPs, the alginate/xanthan gum FBS materials include fillers to alter the physical appearance and fluid properties of the material. The optimized FBS consisted of alginate (1% w/v) and xanthan gum (5.0 x10-3 w/v %), 2 mM CaCl2, ferric citrate (0.5% w/v), magnesium silicate (0.25% w/v), Allura red (2% w/v), 0.025% v/v Tween 20 and 9.5% v/v MPs. The FBS was tested in passive dripping experiments relevant to BPA scenarios at various impact angles. The spreading ratio (Ds/D0) was determined for 90 degree stains made on a paper surface and compared to bovine blood where the FBS was shown to simulate accurate and predictable spreading behaviour. In addition, we simulated other common BPA scenarios (e.g., impact patterns) and evidence processing potential. The FBS could be swabbed, and the DNA could be extracted, amplified, and genotyped analogous to human blood evidence. A stability test was also conducted which revealed a shelf-life of up to 4 weeks where the material remains relevant to human blood at physiological temperature.
Data-Driven Models for Predicting Intrinsically Disordered Protein Polymer Physics Directly from Composition or Sequence
Authors: Chao Tzu-Hsuan , Rekhi Shiv , Mittal Jeetain , Tabor Daniel P.
Published: March 2023

The molecular-level understanding of intrinsically disordered proteins is challenging due to experimental characterization difficulties. Computational understanding of IDPs also requires fundamental advances, as the leading tools for predicting protein folding (e.g., Alphafold), typically fail to describe the structural ensembles of IDPs. The focus of this paper is to 1) develop new representations for intrinsically disordered proteins and 2) pair these representations with classical machine learning and deep learning models to predict the radius of gyration and scaling exponent of IDPs. Here, we build a new physically-motivated feature called the bag-of-amino-acid-interactions, which encodes pairwise interactions explicitly into the representation. This feature essentially counts and weights all possible non-bonded interactions in a sequence and thus is, in principle, compatible with arbitrary sequence lengths. To see how well this new feature performs, both categorical and physically-motivated featurization techniques are tested on a computational dataset containing 10,000 sequences simulated at the coarse-grained level. The results indicate that this new feature outperforms the others and possesses solid extrapolation capabilities. For future use, this feature can potentially provide physical insights into amino acid interactions including their temperature dependence, and be applied to other protein spaces.
Industry-Level Evidence of J-Curve Effects in the SACU Region
Authors: Mhaka Simba , Ncwadi Ronney , Phiri Andrew
Published: March 2023

Our study examines the cointegration relationship between exchange rate movements and trade balances for the five Southern African Customs Union (SACU) countries between 1995 and 2020. We disaggregate trade activity at an industry-level for 19 trade products and then determine whether industries benefit or are at a disadvantage during periods of currency depreciations over the short- and long-run. Applying pooled mean group (PMG) estimators to panel regression specifications of the industry-level J-curve, we find that exchange rate depreciations would be beneficial in 8 out of the 19 trade industries in the SACU region whilst harming theremaining 11 industries. In the strict, theoretical sense we only find J-curve effects in 6 of the 19 industries in which exchange depreciation initially hurt trade balances and then ‘adjust’ towards positive long-run effects. Altogether, we advise policymakers in SACU countries to consider devising (i) export-oriented policies for industries whose trade balance is strengthened by currency depreciations and (ii) import substitution industrialization policies and currency-risk mitigation strategies for industries whose trade balance is weakened by currency depreciations.
Language Management Strategies and Slovenian SMEs: An Update on Recent Developments
Authors: Riznar Igor , Puntar Anja
Published: March 2023

In line with numerous studies, export success of small and medium-sized enterprises (SMEs) could be considerably improved were companies aware of the importance of foreign language skills among their employees. In other words, many business opportunities are lost within the European Union because of the lack of language skills. Many authors report that adopting a language management strategy is linked to a significant increase in companies' export sales. The ELAN (Effects on the European Economy of Shortages of Foreign Language Skills in Enterprise) findings should also be considered because of the relatively high importance of SMEs in providing employment. This article investigates, by means of a questionnaire sent to 1499 Slovenian exporting SMEs from various industries, how aware these companies are of the ELAN findings, and which language strategies they have implemented in their business operations. The findings of our 2021 study revealed that Slovenian exporting SMEs are slowly becoming more aware of the benefits of language management strategies, but that some improvements are nevertheless still possible.
Job crafting and innovative behavior among hospitality workers: The moderation effect of work engagement
Authors: Kaur Gursweet , Rahmadani Vivi Gusrini
Published: March 2023

The COVID-19 pandemic impacted a decline in hotel occupancy rates in the hospitality sector worldwide, including in Indonesia. Therefore, hotel management and workers need innovation to attract customers by crafting their jobs and developing original and creative ideas. Moreover, employees’ work engagement will also support the emergence of innovative behavior. This study aimed to explore whether work engagement moderates the relationship between job crafting and innovative work behavior among hotel employees. This research was conducted at one of the four-star hotels in Medan, with 109 employees chosen with a total sampling technique to participate in this study. The innovative behavior scale, the job crafting scale, and the work engagement scale were used to collect the data, which were then processed using the moderated regression analysis method with Process Macro Software. The results show job crafting has a significant positive effect on innovative behavior, and work engagement moderates the effect of job crafting on innovative behavior. Increasing innovative behavior can be achieved by increasing job crafting and work engagement in the organization. The implication of this study may assist the hotel management in assessing its employees and then implementing training on job crafting and work engagement to improve innovative behavior.

Authors: Anasuyari Ni Komang Yastri , Latifah Melly , Yuliati Lilik Noor
Published: March 2023

The COVID-19 pandemic has impacted every element of adolescent life worldwide, including Indonesia. This study intended to examine how adolescents' loneliness and mental health during the COVID-19 pandemic are affected by their family relationships and online friendships. This study collects data using an online questionnaire. The Mental Health Continuum-Short Form, the UCLA Loneliness Scale Version 3, the Brief Family Relationship Scale, and the Online Friendship Scale were used to collect the data. Two hundred ninety-two students aged 12-18 participated in data gathering in Jakarta, Indonesia, between March and April 2021. Descriptive, correlation and Structural Equation Modeling (SEM) analyses were conducted using SPSS 25.0 and LISREL 8.80. This research revealed that family relationships and online friendships had a negative effect on loneliness. Family relationships favorably impact adolescent mental health, but loneliness negatively impacts it. Furthermore, family relationships and online friendships indirectly affect adolescents' mental health through loneliness. These findings may implement in developing interventions to assist adolescent mental health during the COVID-19 pandemic in Indonesia.

Authors: Elgeka Honey Wahyuni Sugiharto , Pujibudojo Jatie K.
Published: March 2023

Online learning has become a solution for the world of education, including universities, during the COVID-19 pandemic. Every student behaves differently in addressing online learning in their lives. This research aimed to explore the role of self-regulated learning on psychological distress among university students in the online learning process during the COVID-19 pandemic. Four hundred sixteen students participated online survey and completed Depression Anxiety Stress Scale – 21 and the Online Self-Regulated Questionnaire. The correlation results show that self-regulated learning negatively correlates with depression, although the level of depression is mild to moderate. Besides that, students in the third and fourth years of study found that they had a higher score of depression on online learning than the first and second years of study. Therefore, the capacity to motivate and identify the direction of self-regulated learning will make students actively participate in online learning and could adapt to online learning during the COVID-19 pandemic. Thus, more self-regulate learning relates to lower depression among students.
A produção semiótica de significados num espetáculo de estilo: linguagens culturais e criativas
Authors: Cantú William Afonso , Pinheiro Gomes Nelson
Published: March 2023

O estudo da moda permite-nos compreender a cultura e as diferentes formas de expressão individual. A revisão de literatura deste trabalho indicou que existem várias perspetivas de análise da moda e dos seus objetos, o que lhe confere um caráter dinâmico. No que diz respeito à sua relação com a semiótica, a revisão de literatura enfatiza a análise de marcas, publicidades e fotografias. Isso enaltece uma lacuna nos estudos de outros tipos de produção cultural, como os desfiles. Ao compreender os desfiles, podemos decodificar novas dinâmicas no sistema de moda, pois eles são ricos em significados e representam a cultura onde as marcas estão inseridas. Dessa forma, o principal objetivo desta pesquisa é compreender os padrões de significado representados em desfiles de moda unificados. A pesquisa seguiu um roteiro metodológico baseado principalmente na abordagem semiótica barthesiana. Para tanto, recorreu-se a uma análise semiótica de um estudo de caso composto pelos desfiles unificados Gucci. O roteiro analítico destacou a existência de elementos específicos nas narrativas essenciais para a compreensão do DNA da marca. Também podemos observar que os elementos de um desfile unificado não retiram o impacto das mensagens nas narrativas da marca. Ao explorar essas articulações, pudemos perceber os locais de sentido em signos específicos dos desfiles, destacando o seu papel como significante cultural.
Da invisibilidade à aparição discreta: um estudo sobre velhice e moda na revista Claudia (1997-2010)
Authors: Pires Teixeira Débora
Published: March 2023

O presente artigo tem como objetivo analisar a representação da velhice nos conteúdos de moda da revista Claudia, buscando desvelar como ocorre e quais são os mecanismos utilizados pelo periódico nessa construção. Metodologicamente, trata-se de uma pesquisa com abordagem qualitativa, classificada como documental e interpretativa, realizada em 156 edições da revista, publicadas entre janeiro de 1997 a dezembro de 2010. O referencial teórico mobilizado para este estudo partiu da perspectiva cultural, com enfoque na obra da autora Julia Twigg (2007, 2008, 2010, 2013, 2017, 2018). O corpus revelou que o conteúdo de moda da revista Claudia negociava com a idade pela utilização de três estratégias: censura, diluição e homogeneização/apagamento. Há, por parte da publicação, um padrão normativo imposto às mulheres mais velhas, uma moralidade que coíbe a exposição e a visibilidade de seus corpos, no qual se enquadra o uso de cores neutras, modelagens retas e peças atemporais. Em outros espaços, fora do conteúdo de moda, notou-se movimentos de resistência, que se afastam desse padrão sugerido pela editoria.
Corpo, vestuário e efeitos de autenticidade na política brasileira: análises sociossemióticas
Authors: Demuru Paolo , Pimenta Rodrigues de Oliveira Felippe
Published: March 2023

Este artigo propõe uma investigação acerca dos perfis de lideranças políticas brasileiras na rede social Instagram, a fim de analisar as estratégias discursivas de construção da autenticidade centradas nos dispositivos semióticos do corpo e do vestuário. A este respeito, temos como hipótese que, sob o perfil semiótico, o valor de autenticidade é construído a partir de arranjos figurativos e plásticos capazes de investi-los de uma aura de aparente simplicidade, um simulacro do sujeito comum que posta nas redes sociais, um cidadão que goza de uma vida comum e em comum com seus seguidores-eleitores. Para essa investigação e análise contamos com o suporte do referencial teórico-metodológico da semiótica discursiva de orientação greimasiana, em particular da semiótica figurativa e da semiótica plástica, e das recentes contribuições da semiótica no estudo do populismo contemporâneo.

Authors: Uddin Md. Sabur
Published: March 2023

In this analysis, we apply prominent mathematical systems like the modified (G’/G)-expansion method and the variation of (G’/G)-expansion method to the nonlinear fractional-order biological population model. We formulate twenty-three mathematical solutions, which are clarified hyperbolic, trigonometric, and rational. Using MATLAB software, we illustrate two-dimensional, three-dimensional, and contour shapes of our obtained solutions. These mathematical systems depict and display its considerate and understandable technique that generates a king type shape, singular king shapes, soliton solutions, singular lump and multiple lump shapes, periodic lump and rouge, the intersection of king and lump wave profile, and the intersection of lump and rogue wave profile.

RITUALISM IN BUDDHISM IN THE INTERPRETATION OF RUSSIAN BUDDHOLOGY (1831-1991)
Authors:   St. Tikhons Orthodox University, Paramoshkin Yuri A.
Published: March 2023

The attitude towards Buddhism among its researchers has always been different. In the works of the first Buddhologists there was a separation of the philosophical conceptions of the Buddhist religion and its ceremonial side, and the latter was often either criticized or ignored altogether. In the postrevolutionary period many Buddhist works paid little attention to the ritual side of Buddhism, and the situation changed only in the post-war years. The article examines the works of domestic Buddhologists of the Russian Empire and the Soviet Union from 1831 to 1991, where the lower boundary of the period under consideration is the date of publication of the first academic work on Buddhology, and the upper one is the collapse of the USSR
Pore Pressure Configuration in Balikpapan Bay Area
Authors: Lie H.S.
Published: March 2023

The Sepinggan Strike-Slip Fault System is widely known to control the structural configuration and hydrocarbon distribution in the Balikpapan Bay Area. The fault system extends more than 70 km trending SE-NW and is part of the greater Adang Fault Zone. This strike-slip fault system traverses several fields and plays a significant role in hydrocarbon accumulation in the Balikpapan Bay Area. More than 100 MMBOE hydrocarbons have been produced to date in this area from two group plays, Early Miocene Deltaic Play, and Middle Miocene – Pliocene Deltaic Play. Future exploration in this area is directed towards the more challenging plays with overpressure zone. This study looks at eleven fields in the Balikpapan Bay to understand the pore pressure distribution across the structurally complex area. Multi-vintage seismic, exploration and development wells are utilized for this purpose. This study has found that structural geology controls the pore pressure configuration in this area. The fault block movement seems to correlate to the top of overpressure. In the uplifted fault blocks, the top overpressure appears at the shallower depth even fully dissipated in highly eroded areas. Otherwise, in the lowered fault blocks, the top overpressure appears at the deeper depth. The top of overpressure in the Balikpapan Bay appears at different stratigraphic intervals across the observed fields. The top of overpressure varies from Early Miocene to Middle Miocene to the present day. The result of this study provides an insight into pore pressure configuration in structurally complex areas.
Pertagis (Pertamina Gis), The Journey to One Map Pertamina to Support The Borderless Operation Excellence of Sub Holding Upstream

Published: March 2023

The development of PERTAGIS (PERTAMINA GIS), a Geospatial Information System is one response to the new restructuring challenge of PERTAMINA Sub Holding Upstream (SHU) within the regionalization framework which significantly changes the operating model and asset management. To avoid geospatial data silos, the concept of data integration is very necessary for smooth, effective and efficient decision making because the data presented is unlimited & comprehensive, including in terms of analysis. In addition, as part of the Digital Transformation SHU program, this system is designed in accordance with the Indonesian government's laws and regulations (Kebijakan Indonesia Satu Peta) with the aim of integrating national geospatial data owned by all ministries into the SIGN (Sistem Informasi Geospasial Nasional). However, this massive integration of some existing portal & applications with various specifications, huge data volumes, disparate databases, different data structures and owned by many entities is being a big challenge in establishing an agile proven system among multiple entities and functions within SHU, regions & zones as a whole. For this reason, it is officially necessary to prepare a blueprint document as the road map of ongoing system development which includes 5 key components, namely strategy, governance, data & technology, engagement and skills development, when fully well-developed and implemented would help establish a vision and path for an organization's success and transformation leveraging geospatial resources in a complex system with evolving priorities to business goal and business challenging of SHU and PERTAMINA in general.
Geochemical Analysis in Supat Field, South Sumatra Revealed Different Oil Characteristics From The Same Source Rock
Authors: Permana B.R.
Published: March 2023

Supat is an oil field in Corridor Block in the South Sumatra Basin. This field has two main oil-bearing reservoirs, named the Talang Akar Formation (TAF) and the K-limestone Formation (KLS). These reservoirs are not in pressure communication. TAF Formation has been produced for 28 years while KLS was assessed and proved as an oil reservoir in 2014 and 2015. However, KLS did not have continuous production due to flow assurance problem. This paper discusses the geochemical analyses performed to characterize oil properties from both formations (TAF and KLS). The analysis that consists of SARA (saturated, aromatic, resin, and asphaltene) compositions, API gravity, pour point, WAT (wax appearance temperature) and WDT (wax disappearance temperature) were performed on oil samples. High Temperature Gas Chromatography and Mass Spectrometry (HTGC-MS) was also conducted on the saturated and aromatic fractions of the oils for biomarker analysis. Based on the physical oil characteristic analysis, the oil produced from TAF and KLS is different in term of SARA, API gravity, pour point, WAT and WDT. The analysis describes that producing oil from TAF has a propensity to form wax whereas the producing oil from KLS tend to form asphaltene. Nevertheless, the results of Gas Chromatography and Mass Spectrometry analysis indicate that the oils from both formations have same source progenitor which is terrestrially derived higher land plant (D/E Type organo-facies) source rock. This source rock was deposited in fluvio-deltaic or transitional system. It is then concluded that the variation in oil composition occurred due to alteration during and post migration and accumulation.
New Insights Into The Tertiary Petroleum Systems of The East Java Sea and Southern Makassar Strait, Indonesia
Authors: Beenfeldt J.
Published: March 2023

Modern broadband seismic data provides new insight into the Eocene-Miocene syn- to early post-rift sections of the East Java Sea (North Madura) and South Makassar Basin. Previous subsurface imaging suffered from shallow imaging obstacles and “hard” Eocene-Miocene carbonates, which render the interpretation of basement and overlying early syn-rift sections difficult. Thickness and distribution of these syn-sift sections differ significantly when comparing the North Madura area and the South Makassar Basin. Late syn- and early post-rift carbonate development also differs significantly in that a carbonate inter-reef blanket interrupted by pinnacle reef formation on top of a syn-rift section is present in North Madura. This contrasts with carbonate sections including bioherms that are controlled by the geometry of the underlying basement substrate, and which occur over extensive parts of the western South Makassar Basin. Early syn-rift including source rocks appear limited, requiring petroleum charge generation and migration from the central South Makassar Basin or the Central deep depression.
The Innovation of Making Exhaust Emissions Calculation Applications (PEGANG) for CPP Gundih Using The Non-Clause Method at PT. Pertamina EP Cepu, Cepu Field
Authors: Abidin A.Z
Published: March 2023

The Central Processing Plant (CPP) Gundih is a gas plant that can produce 13MMSCFD acid gas after the purification process. Most of the composition of the acid gas consists of H2S & CO2. Half of the total acid gas is converted into sulphur pellets and the remaining 6.5MMSCFD is burned in the Thermal Oxidizer (TOX) unit. It is known that burning H2S will produce exhaust gas emissions in the form of SO2 content. In accordance with the mandate of the Ministry of Environment No.13 of 2019 concerning "Quality Standards for Emissions from Immovable Sources for Oil and Gas Businesses and/or Activities", is an obligation for all subsidiaries to report the total exhaust emissions produced in each equipment, either continuously or intermittently. This calculation will be very important when the scheme from the Ministry of Finance will impose exhaust emission taxes and carbon credits starting in 2023. The calculation of venting gas emissions in the TOX unit which has so far been carried out using the Clause Method is not representative enough to display the actual total gas emissions. Based on the calculation formula from external parties, the entire acid gas produced is considered as exhaust emissions. However, in actual conditions only half of the total acid gas is vented to the TOX unit and the remaining half is converted to sulphur using the Biological Sulfur Recovery Unit (BSRU). Based on that problem, with the Non-Clause Method approach through the PEGANG application, the separation of the calculation of venting acid gas to TOX and to the BSRU unit resulting in the calculation of exhaust gas emissions at CPP Gundih tends to be smaller and more representative. The PEGANG application is very useful as it can be an indicator of the amount of emissions that are released to the environment, especially on the equipment in CPP Gundih.
