The Challenges and Performance of Female-Owned Entrepreneurial Firms and Management Strategies
Authors: Bharadwaj Raktima , Das Rajoshi , Majumdar Anindita
Published: April 2023

In India, society has set some unsaid rules. Some find it difficult to accept women in a work environment because of the patriarchy. Hence it becomes difficult for a woman to break the stigma and establish her own firm. The paper aims to look at the number of threats and challenges that female entrepreneurs face from both micro and macro perspectives. Covid has bought both temporary change (workplace change) and permanent change (shutting down a service/facility) in an organisation. A small new rising firm would not have the capacity to sustain during this time, and females who try to set up small businesses to run their families are mentally affected. This article is an extensive review from earlier works to understand the challenges faced by female owned entrepreneurial firms and their performance during the change brought by COVID times. This article explores the factors influencing the development of female entrepreneurs as well as measures required to enhance the scenario. This paper also aims to explore the psychosocial aspect of changes brought by female owned entrepreneurial firms.

Authors: Gökbunar Ramazan , Küçükbay Füsun
Published: April 2023

The current survey study was designed to explore the mental health status, reactions, concerns, and expectations of university students during the COVID-19 pandemic, and the potential relationships between mental health and their reactions and macroeconomic expectations. The results show that the student's mental health worsened during Covid-19 which accelerated their pessimism, causing a decline in their academic success and purchases, and causing an increase in their negative expectations about macroeconomic indicators. The results also show that concerns about the economy, financial situation, and future are associated with mental deterioration. The analysis reveals that the most prevalent concern among the students is anxiety about the future. Moreover, gender, educational level, and income level also significantly impact the reactions and the macroeconomic expectations of the students.

Published: April 2023

Adult online learning can be a very complex and volatile process, often leading to different expected and/or unexpected outcomes attributed to both learner-specific and non-learner-specific motivational factors. Despite the growing research literature recently, most studies examine online adult online learning motivation only from one perspective at a particular time. Therefore, this chapter aims to conduct a systematic meta-review to provide an integrated overview of the relevant research literature in the past four decades.

Embracing the Dream of an Education
Authors: Collins Linda Diann
Published: April 2023

Students have not changed much over the years. Their desire to learn, be productive, and to share with others to make a better life for themselves, their family, and the community have pretty much stayed the same. What has changed is the vehicle being used. Technologies such as personal computers and the internet have been around since the 1980s; however, they did not come into common use until the late 1990s. As personal computers became a burgeoning industry in the 1990s everything has changed in the world, or has it? Many take for granted that access to the internet and computers are part of who we are and where the world has taken us. This is the reality for many, but not for all, and not even for everyone in the United States. Included is an exploration of the situation on rural American Indian reservations and the challenges and external barriers to accessing needed technologies to be successful. A call to action is included for change and the strategies and practices that could aid in building infrastructures and access to information on rural American Indian Reservations.
The Recycled Story Formula
Authors: Yıldırım Cem
Published: April 2023

Film sequels are often produced to get more out of a successful movie. However, the Superman movies, which were designed as a sequel project from the beginning, stand apart from other film sequels because the production of the first two films started simultaneously. Besides, sequels were announced to the audience in the closing credits of the first two Superman movies. This study argues that the same narrative elements utilized in the first Superman movie made in 1978 were reused in the first two Superman sequels, forming a recycled story formula. Thus, the audience essentially watched the same story with some alterations over and over again. The purpose of this study is to reveal this recycled story formula, which is used in the first two Superman sequels. In this framework, the dramatic structures of the three Superman movies made between 1978 and 1983 will be analyzed by identifying repeated narrative elements and alterations, to reveal the recycled story formula used in the sequels.
An Architectural Review of Harry Potter Series' Spaces
Authors: Yurttaş Neşe Başak , Akyol Cansu
Published: April 2023

J.K. Rowling has detailed the wizarding world she imagined in terms of characters, places, events, and their relations with each other and has established a fantastic world. This world has been processed by putting all the technological possibilities and ingenuity of the Hollywood film industry into action, and as a result, a world-class industrial cinema series has emerged. At the beginning of the story, we encounter a utopian and charming wizarding world where Voldemort loses his influence and is accepted as dead by most wizards, where equality, order, balance, peace, and prosperity prevail. However, in the later parts of the story, with Voldemort regaining power, the wizarding world evolves into an unjust, discriminatory, and evil, that is, dystopian, where pure blood is important. In the study, spaces with philosophical-theoretical-metaphorical references were analyzed and the representative change of physical spaces related to the world of good and evil was examined and evaluated on the timeline.
An assessment of training needs for accessing electronic resources among health professionals in Sri Lanka: a qualitative study
Authors: Sritharan T.
Published: April 2023

This study aimed to assess the training needs for accessing electronic resources among health professionals in Sri Lanka. Thirty two (32) postgraduate medical trainees from 32 medical specialties who were attached to the Postgraduate Institute of Medicine (PGIM) were selected as study population.  Focus Group Discussions (FGDs) were used as the research instrument. Thirty two (32) trainees were divided into four groups; each group consisted of eight (08) participants.  Data was analyzed by using QDA Miner lite open software. The major themes and sub themes were developed from the FGDs with postgraduate medical trainees. Results revealed that postgraduate trainees need information primarily for the purpose of research and publications (78.5% or 22). They also added that they need information for their clinical practices (60.7% or 17) during their PG education. Moreover, almost 100% of the trainees agreed that they need information for writing literature reviews. Majority of the respondents (89.3%) claimed that they search the internet to obtain the required information in view of enhancing and updating their medical knowledge. Most of the respondents (n=16) said that they prefer electronic journals and internet resources because they felt that electronic resources are more convenient and up to date. Further the importance of Evidence Based Medicine and the need for systematic reviews were highlighted at the FGDs. Regarding the format of sources 78% of them preferred to read electronic resources. All the trainees highly impressed that they need training on information literacy skills especially in searching techniques. Almost all trainees accepted that they need professional training in accessing electronic resources. In each group very few trainees (25%) had attended once or twice in the library orientations and hands on workshops on accessing electronic information which were conducted by the PGIM library. From the results of the FGDs, it is concluded that all trainees expect a high skill training programme during their postgraduate medical education. Therefore, this study recommends a well-organized training program including basic computer skills and searching techniques for medical postgraduate trainees.

Authors: Mahmoudieh Mohsen , Kalidari Behrooz , Sayadi Shahraki Masoud , Mellali Hamid , Mirzaie Hamid , Salamati Majid
Published: April 2023

Background:

Bariatric surgery is a surgical procedure for patients with extreme obesity. Enhanced Recovery after Surgery (ERAS) is a method that provides special peri- and post-operation care. Here, we aimed to compare the effects of ERAS and standard recovery cares.

Materials and Methods:

This is a randomized clinical trial that was performed in 2020-2021 in Isfahan on 108 candidates for mini gastric bypass. Patients were then randomly divided into two equal groups receiving ERAS and standard recovery protocols. Patients were examined and visited after one month regarding the average number of hospitalization days, the average days required to return to normal activity or work, occurrence of pulmonary thromboemboli (PTE) and the rate of readmission.

Results:

Patients that received ERAS had significantly lower frequencies of nausea and vomiting (P = 0.032). Patients that received ERAS had significantly lower hospitalization duration (P < 0.001) compared to controls. No other significant differences were observed between two groups regarding surgery complication, re-admission rate and occurrence of PTE (P > 0.99 for all).

Conclusion:

Patients that received ERAS protocol after gastric bypass had significantly lower hospitalization duration and lower incidence of nausea and vomiting. They also had similar post-operative outcomes compared to the standard protocol.
A Comparative Study on the Usefulness of Fractional CO2 and Fractional Er:YAG in Acne Scars: A Split-Face Trial
Authors: Mokhtari Fatemeh , Safavi Zahra , Faghihi Gita , Asilian Ali , Shahmoradi Zabihollah
Published: April 2023

Background:

Acne is a dermatologic condition with a high burden in terms of psychosocial consequences as a result of scars remaining on the skin. Its effects are severe in adolescence and finding treatments with short therapy courses, superior results, and fewer adverse effects are of high importance.

Materials and Methods:

We included 30 individuals with acne vulgaris scars in Al-Zahra academic training hospital from June 2018 to Jan 2019. Each individual received both fractional CO2 and fractional Er:YAG lasers on right and left sides of the face, respectively. Three sessions of laser treatment were applied to each side with one-month intervals. Results were evaluated by patients according to subjective satisfaction and physicians' assessment and photo evaluation by two blinded dermatologists. Improvement was graded by a quartile grading scale: less than 25%: mild, 25% to 50%: moderate, 51% to 75%: good, and 76% to 100%: excellent response. Assessments were obtained at baseline and one month after the last visit.

Results:

Based on subjective satisfaction (p < 0.05) and physicians' assessment (p < 0.01), fractional CO2 laser was significantly more effective than Erbium:YAG laser. Also, Post-treatment side effects were mild and transient in both groups.

Conclusion:

Laser therapies are common in the treatment of scars and each modality has special advantages and disadvantages. Choosing among them should be based on various criteria. Fractional CO2 lasers have been revealed favorable results in most reports. Large comprehensive trials could help experts in choosing among alternatives for different subgroups.

Authors: Movahedi Minoo , Khanjani Somayeh , Shahshahan Zahra , Hajihashemi Maryam , Farahbod Farinaz , Shahsavandi Elaheh
Published: April 2023

Background:

In the current study, we aimed to evaluate the association between pregnancy-related plasma protein-A (PAPP-A) levels measured in the first trimester and pregnancy outcomes.

Materials and Methods:

This is a descriptive-analytical study that was performed in 2019--2021 on 1061 pregnant women in their first trimester. Demographic and basic information of all women were collected. These data included age, weight, parity, and date of delivery. Then the quantity of PAPP-A was recorded in three groups including less than 0.5 MOM, 0.5 to 2.5 MOM, and more than 2.5 MOM.

Results:

Data of 1061 women were analyzed. 900 women (84.8%) had term delivery and 155 women (14.6%) had pre-term deliveries. PAPP-A levels were normal in 83.4% of women. BMI and number of pregnancies had significant relationships with PAPP-A (p < 0.001, P = 0.03 respectively). The mean BMI in mothers with PAPP-A higher than 2.5 was significantly more than mothers with normal or lower PAPP-A levels (26.2 ± 31, P = 0.04). The frequency of term labor in mothers with normal PAPP-A was higher than other mothers (86.3%, P = 0.04). The frequency of preeclampsia in recent pregnancies in mothers with normal PAPP-A was significantly lower than other mothers (p < 0.001) and the frequency of abortions in recent pregnancies in mothers with PAPP-A less than 0.5 was significantly higher than mothers with normal or elevated PAPP-A (p < 0.001).

Conclusion:

Mothers with low PAPP-A levels are more likely to have poor pregnancy outcomes such as abortion, pre-term labor, and preeclampsia.

Published: April 2023

Background:

Cerebral palsy in children is considered a non-progressive brain injury due to abnormal brain development. The aim of this study was to investigate the effect of eight weeks of aquatic exercises on muscle strength in children with cerebral palsy.

Materials and Methods:

This study was performed on three boys with cerebral palsy with a mean age of 6.5 years. In this research, a single case study method with A1-B-A2 design has been used. After determining the position of the baseline, the intervention began and during 24 sessions of individual intervention, aquatic exercises were presented to the subjects and all three subjects were followed up for 2 consecutive weeks and one month after the end of the intervention. The strength of the flexor muscles of the arms and legs was measured by a power track dynamometer made by JTECK with a threshold of 4.4 N.

Results:

Based on the indicators of descriptive statistics and visual analysis, the intervention was effective for all three participants in muscle strength, and the strength of individuals after the intervention has improved compared to the baseline stage (percentage). Information overlap for the first and second participant in the strength of right thigh flexors was 75% and for the third participant was 100%. The strength of the upper and lower torso muscles improved after the end of the training compared to the basic stage.

Conclusion:

Aquatic exercises can increase the strength of children with cerebral palsy and provide a favorable environment for children with cerebral palsy.

Authors: Yavari Masoud , Modaresi Seyed Masoud , Hassanpour Seyed Esmail , Moosavizadeh Seyed Mehdi , Tabrizi Ali
Published: April 2023

Background:

A trigger finger is recognized as the most common hand tendinopathies that reduce functional ability. The present study compares the clinical outcomes of open classic release surgery with ultrasound-guided percutaneous surgery in cases of multiple finger involvement.

Materials and Methods:

A cohort study has been performed from March 2019 to December 2020 by participating 34 trigger finger patients with multiple involvements. These patients were treated using classical open release and ultrasound-guided percutaneous release methods and both methods were compared in patients. The pain severity and functional ability obtained from the quick disabilities of the arm, shoulder, and hand (Quick-DASH) test scores were compared.

Results:

The pain intensity in the classical open surgery patients was not significantly different from the ultrasound-guided group, and a one-month follow-up showed that the pain intensity in the ultrasound-guided patients was significantly less than in the other group (P = 0.02). Besides, no significant difference was observed between the functional abilities before and after the one-month follow-up. Indeed, the two groups had the same situations. Also, the recovery time in the ultrasound-guided percutaneous release group was significantly faster than in the other group. These cases had statistical differences as P = 0.001 and P < 0.001, respectively. The surgical release was 100% successful in both groups. The patients' satisfaction rates in the ultrasound-guided and open classic surgery treatment methods were 94.1 and 76.4%, respectively.

Conclusions:

Classical open release and ultrasound-guided percutaneous surgery could successfully treat multiple trigger fingers. However, ultrasound-guided percutaneous surgery provided faster recovery and less pain intensity than the other method.

Authors: Raykar Priyadarshini Shivaram , Banur Anup , Mahanthappa Gururaj , Ajith Eti , Bondade Kushal , Angadi Siddharth , Jith Jisna
Published: April 2023

Background:

Pneumothorax, pneumomediastinum, and subcutaneous emphysema are few of fatal complications noted in patients with COVID-19 pneumonia. Various studies have shown prevalence of pneumothorax ranging between 1% and 2% in COVID-19 pneumonia.

Materials and methods:

A total of 10 inpatients admitted with COVID-19 disease confirmed by RT-PCR test who developed pneumothorax, pneumomediastinum, and subcutaneous emphysema during hospital stay by sequential sampling method were included in the study. Demographic data, duration of hospital stay, underlying comorbidities, predisposing factors, radiographic characteristics, and mode of oxygen delivery were collected and analyzed.

Results:

In our study, mean age group of patient who developed pneumothorax, pneumomediastinum, and subcutaneous emphysema was 39.8 years. Male to female ratio was 9:1. Mean time duration of onset of pneumothorax, pneumomediastinum, and subcutaneous emphysema from the day of hospitalization was 17.3 (8–30) days. Nine patients were on NIV (non-invasive ventilation) while one patient was on NRBM. Right sided involvement was noted in five patients, three had left sided involvement, and two patients had bilateral pneumothorax. Five patients had pneumomediastinum and subcutaneous emphysema along with pneumothorax. All patients received antivirals (Inj. Remdesivir), systemic steroids along with other supportive treatment. Except for one patient, all patients who developed pneumothorax, pneumomediastinum, and subcutaneous emphysema succumbed. All patients’ chest radiograph was consistent with COVID-19 pneumonia. One patient had pulmonary cyst on Computerized Tomography (CT) thorax which was done post intercostal drainage of pneumothorax. Mean time of death after development of pneumothorax, pneumomediastinum, subcutaneous emphysema was 4.3 days. Comorbidities observed were bronchial asthma, obesity, and status post Caesarian section.

Conclusion:

Development of pulmonary barotrauma in COVID-19 patients is associated with high mortality. Presence of pulmonary cyst, prexisting bronchial asthma, obesity, systemic steroids are possible poor determinants.
Bilateral pneumothorax in COVID recovery
Authors: Joshi Sharad , Bhatia Ankit , Tayal Nitesh
Published: April 2023

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection leading to coronavirus disease 2019 (COVID-19) mainly affects the lungs leading to complications of acute lung injury. Pneumothorax has been observed as a complication in COVID-19 cases requiring urgent intervention and may indicate poor prognosis in view of severe underlying lung damage. Bilateral pneumothorax is an even dreaded and rare complication requiring immediate recognition and management. We present two similar cases of bilateral pneumothorax with COVID-19 pneumonia with none requiring positive pressure ventilation and no preexisting lung disease. Our cases are a reminder about the severity of lung damage in COVID-19 and that a good vigilance is required in the event of an acute deterioration.

Authors: Jain Sumit Kumar , Kumar Krishnapriya S.
Published: April 2023

A 46-year-old male patient presented with high-grade fever, chills, hemoptysis, myalgia, acute onset of dyspnea, and right-sided chest pain. Emergency chest radiograph revealed right hydropneumothorax. On insertion of intercostal drain, there was a sudden gush of hemorrhagic fluid suggestive of hemothorax. There was no history of trauma or bleeding tendencies. Laboratory investigations revealed thrombocytopenia and positive dengue immunoglobulin M (IgM). The patient improved on aggressive supportive therapy. Subsequently, he underwent video-assisted thoracoscopic surgery (VATS) for non–re-expansion of lung. We report here a rare case of dengue hemorrhagic fever presenting as unilateral hemopneumothorax. Nontraumatic hemopneumothorax as an initial presentation of dengue is being reported for the first time in literature.
Asthma

Published: April 2023

Asthma is a complex chronic inflammatory disease of the bronchioles characterized by airway hyperresponsiveness, bronchial hyperresponsiveness, and airway obstruction. Asthma is classified into various types. The epidemiological studies say that there are approximately 310 million people affected. The asthma prevalence is increasing considerably among developing and developed nations. Many of the patients remain undiagnosed because of the lack of healthcare facilities. Asthma is a complex disease that involves several cells (T-lymphocytes, B-lymphocytes, mast cells, eosinophils, dendritic cells, macrophages, chemokines, cytokines, histamines) that when activated can trigger the pathogenesis of asthma. The pathogenesis of each cell varies from the other. It also varies with age, gender, and exposure type.
Epsilon-regularity for the solutions of a free boundary system
Authors: Maiale Francesco Paolo , Tortone Giorgio , Velichkov Bozhidar
Published: April 2023

This paper is dedicated to a free boundary system arising in the study of a class of shape optimization problems. The problem involves three variables: two functions

u

and

v

, and a domain

\Omega

; with

u

and

v

being both positive in

\Omega

, vanishing simultaneously on

\partial\Omega

, and satisfying an overdetermined boundary value problem involving the product of their normal derivatives on

\partial\Omega

. Precisely, we consider solutions

u, v \in C(B_1)

of

-\Delta u= f \ \text{ and } \ -\Delta v=g \quad\text{in }\Omega=\{u>0\}=\{v>0\},

\frac{\partial u}{\partial n}\frac{\partial v}{\partial n}=Q \quad\text{on }\partial\Omega\cap B_1.

Our main result is an epsilon-regularity theorem for viscosity solutions of this free boundary system. We prove a partial Harnack inequality near flat points for the couple of auxiliary functions

\sqrt{uv}

and

\frac12(u+v)

. Then, we use the gained space near the free boundary to transfer the improved flatness to the original solutions. Finally, using the partial Harnack inequality, we obtain an improvement-of-flatness result, which allows to conclude that flatness implies

Ways of Knowing Agency and Development: notes on the philosophy of science and the conduct and use of inquiry
Authors: Garcés-Velástegui Pablo
Published: April 2023

Development is a value-laden concept and, as such, an essentially contested issue. To different extents, different ideas of development entail different assumptions about human agency. Although economics has been the most influential discipline, increasingly different accounts highlight distinct features of human beings and the contexts they inhabit, which lead to different implications. This article seeks to delineate the boundaries of the discussion and map out what are arguably the main alternatives within the field. Since such discussion deals with the question of what human action is, the argument is elaborated from the philosophy of science. Contra convention, the discussion uses a philosophical ontology, which is concerned with out connection to the world. Jackson’s heuristic is adopted to generate four philosophies of science and four notions of agency, regarded as ideal typical. Neopositivism advances a rational agent, reflexivity suggests a patient, critical realism furthers an interagent, and analyticism proposes a transagent. This article invites scholars and practitioners interested in this increasingly interdisciplinary area to raise their awareness regarding the foundations on which their ideas about human agency build and note the implications they have for the production and consumption of knowledge.
Stateful Realizers for Nonstandard Analysis
Authors: Dinis Bruno , Miquey Étienne
Published: April 2023

In this paper we propose a new approach to realizability interpretations for
nonstandard arithmetic. We deal with nonstandard analysis in the context of
(semi)intuitionistic realizability, focusing on the Lightstone-Robinson
construction of a model for nonstandard analysis through an ultrapower. In
particular, we consider an extension of the $\lambda$-calculus with a memory
cell, that contains an integer (the state), in order to indicate in which slice
of the ultrapower $\cal{M}^{\mathbb{N}}$ the computation is being done. We pay
attention to the nonstandard principles (and their computational content)
obtainable in this setting. In particular, we give non-trivial realizers to
Idealization and a non-standard version of the LLPO principle. We then discuss
how to quotient this product to mimic the Lightstone-Robinson construction.
Can Experience Determine the Adoption of Industrial Revolution 4.0 Skills in 21st Century Mathematics Education?
Authors: Ayanwale Musa Adekunle
Published: April 2023

Teachers in secondary schools were studied to determine their readiness to adopt fourth industrial revolution (4IR) technologies to enhance their teaching practices and student learning. Through Industry 4.0, technologies are also becoming available as products for education, transforming the rules and norms of education. Secondary school mathematics teachers in Nigeria must prepare themselves to embrace digital skills so that they will be ready for new teaching and learning processes that are being introduced by these new digital tools. In this study, a cross-sectional quantitative approach was used. The data were collected using a self-developed instrument with a content validity index of 0.96 and a MacDonald Omega reliability index of 0.84. A purposive sampling technique was used to select 211 mathematics teachers in three Lagos State education districts. Analyses of the obtained data were performed using descriptive statistics and ANOVA at a significance level of 0.05. Results indicate that mathematics teachers are ready to integrate 4IR skills and emerging technologies into their classrooms. In addition, the willingness of participants to adopt relevant 4IR skills across their years of experience was statistically significant. A new path is charted for school administrators, mathematics teachers, and stakeholders in the education sector to assist in policy design toward 4IR, thereby contributing to the existing literature on adopting emerging technologies to teach mathematics education in sub-Saharan Africa.

At present, there are no quantitative studies of the dependence of the index of protection of personal data of actors in social medias on the parameters of its centrality, so this article presents the results of such researches in this area. Since the system of information protection of a social media network is nonlinear and depends on the parameters of a specific indicator of its centrality, mathematical equations have been developed to study the quantitative indicators of such a system, and the stability of the system has been investigated, which is graphically illustrated. The results obtained allow network administrators to analyze the behavior of the security system stability and take technical actions (operating system, firewall, network filter, etc.) that will keep the security indicator within the specified limits.
Cultura anulării, între revanșă istorică și poetică futuristă restaurată
Authors:   University of Arts Târgu Mureș, Păsăreanu Eugen
Published: April 2023

The study aims to analyze the phenomenon of cancel culture and the references that can be drawn between the subsumed manifestations of cancel culture and futurism, as defined at the beginning of the twentieth century by the Italian poet Filippo Tommaso Marinetti. By reviewing the changes that the artistic avant-garde brings to the arts and observing how the twentieth century highlights art as a statement and the subjectivity of the artist as a unique landmark, the paper identifies a tendency of political and social actions to be inspired, although not assumed, by a poetic area, by a high and permissive invisible that justifies, beyond ideology, social behaviors. Beyond the stakes of historical reparation and prevention of discrimination, which the cancel culture proposes, we will try to identify a possible cause of the poetic anchoring of the phenomenon, as well as the risks associated with this inverted mimesis: a reality which imitates art in order to preserve the vitality and the expressiveness of its actions.
„Somnul rațiunii naște monștrii”
Authors:   Theatrical and Multimedia Research Institute, University of Arts Târgu Mureș, Dan Marcela Livia
Published: April 2023

The sudden appearance of a term imported from across the Atlantic - almost unknown until a few months ago - is spectacular. Cancel culture started with a noble goal, at least on the surface: to suppress those who make racist, homophobic speeches or promote any kind of hatred against a person. During the COVID-19 pandemic, cancel culture began trending again. This concept was made possible with the emergence of the Black Lives Matter, #MeToo and LGBTQ+ movements which were over-promoted on social media platforms like YouTube and Instagram. Each movement uses its own definition, contradicting the others, sowing confusion, stirring up anger, and contempt. The culture of nullification denies the very notion of truth and leads to extreme polarization in society, resulting in unhealthy violence in debate. These "condemnations" are aimed at university professors, writers, intellectuals, journalists, columnists, producers, actors, and anyone who dares to "offend" certain minorities or the dogmas of certain left-wing circles, even with a left-wing phrase. As a result of this phenomenon of cultural cancellation, books, films, and cartoons have begun to be altered or banned. Journalist, essayist, and researcher Alvaro Vargas Llosa (son of the famous writer Mario Vargas Llosa) believes this practice threatens democracy and is reminiscent of a dictatorship like North Korea.
L’écriture romanesque d’Édouard Glissant : une stratégie rhétorique subversive, une anti-poétique et une esthétique composite
Authors:   Université de Tunis, Rhimi Mohamed Lamine ,   Université Islamique Al-Imam Muhammad Ibn Saoud
Published: April 2023

Edouard Glissant denounces all forms of standardization, which model cultures to which he proposes an erratic and eccentric thought. It is specifically in that context that our article reexamined the question of Glissant’s subversive rhetorical strategy by relating it to the judicial impetus. In fact, it’s a question of a counter-rhetoric that underpinned not only anti-poetic, but also composite aesthetic. This is how the West Indian novelist-orator tries to annul cultural typicality and cultivate the intermixing between different human imaginations.
Analysis of Steel Buildings with Steel Plate Shear Walls at the Corners with Varying Thickness
Authors: Banu Aysha , S Anila
Published: April 2023

Nowadays the construction of steel buildings is very common. When a building's height increases, its stability is taken into account. Shear walls have to be added to these structures for them to endure the lateral loads caused by wind and seismic activity. Steel plate shear walls (SPSW), one of the shear wall types, are the most efficient since they are lighter and thinner, enhancing the architectural space and rigidity of the structures. This study employs ETABS software to display the seismic analysis of a 15-story steel structure in seismic zone III that has steel plate shear walls at the corners and centre. This article also compares the performance of another 15-story steel building with steel plate shear walls of different thicknesses (15mm, 20mm, and 25mm). The steel building with the thicker steel plate shear walls at the corners performs better in terms of storey displacement and storey drift when compared to other structures. According to IS 1893:2016, the models are examined using the response spectrum method.
Analysis of the Efficiency of the Use of Potato Farming Production Inputs in Ngaduman, Getasan District, Semarang Regency
Authors: Aprilia Yohana , Prihtanti Tinjung Mary
Published: April 2023

The right allocation of production inputs will provide benefits for farmers. Farmers cultivate potato with different allocation of production inputs. The wrong understanding of the assumption that the more production inputs allocated, the higher the productivity of the crops cultivated, is the cause of the higher production costs incurred by farmers, causing inefficiency. The purpose of this study was to analyze the effect of the use of production inputs and the allocative efficiency of seeds, fertilizers Phonska, fertilizers Za, pesticides, and labor on the productivity level of potatos farming. The research was conducted through interviews with 30 potato farmers as respondents who were selected through purposive sampling technique. The data were analyzed using the Cobb-Douglas production function model and allocative efficiency analysis. The results showed that land area and labor had a significant positive effect on potatos productivity, while seeds, fertilizers, and pesticides had no significant effect on potatos productivity. In potato farming in Ngaduman, seeds and labor production inputs are not allocatively efficient, while production inputs for fertilizers Phonska , fertiluzers Za and pesticide are allocatively inefficient.

The combination of art, religion, and spirituality in Bali is closely related and inseparable from each other and is reflected in mandala paintings. Painting is one of the dynamically developing branches of fine arts in Bali, ranging from classical to postmodern or contemporary. One of the unique paintings with an individual style in the middle of a collective culture is the mandala-themed painting by I Dewa Nyoman Batuan. Hinduism and the community environment inspire him to express his contemplation in the form of paintings. This research focuses on three problem formulations, namely the form of mandala paintings, the factors that encourage their creation, and the meaning of mandalas. This research was conducted using a qualitative method. Data related to the above problems were collected using interviews, observation, literature study, and documentation techniques. Data analysis was sharpened with aesthetic theory, theory of structure and change, and semiotics. These four theories are used to analyze each problem formulation. The results show that the form of mandala paintings by I Dewa Nyoman Batuan is purely an expression of ideas, notions, and personal experiences created freely by combining traditional and modern styles. The combination of the two styles creates new creations that are very distinctive with an abstract-symbolic style. The form of mandala painting includes a combination of line, shape, space, color, and texture. The structure of the painting consists of composition, proportion, unity, balance, rhythm, focal point, and contrast based on the mandala perspective.

Comprender las causas que generan la variabilidad del reclutamiento en las poblaciones marinas constituye uno de los mayores desafíos de la ciencia pesquera. Nuestra capacidad predictiva para explicar estas variaciones es relativamente baja, debido a la interacción de factores exógenos y endógenos, que varían en el tiempo y el espacio dentro de las poblaciones. Con el fin de obtener información sobre las fluctuaciones en el reclutamiento de la merluza argentina (Merluccius hubbsi) del stock patagónico, revisamos los resultados obtenidos analizando la ecología reproductiva, la dinámica trófica y energética durante las diferentes etapas de desarrollo de esta especie y su relación con variables ambientales. Observamos que el potencial reproductivo está fuertemente influenciado por las características parentales, particularmente de las hembras, en cuanto a su tamaño, edad y condición. Esta característica, denominada “efecto materno”, sugiere que la biomasa de la población reproductora, comúnmente utilizada como índice de productividad en la evaluación de pesquerías, es un predictor deficiente del reclutamiento. También observamos que la supervivencia durante los primeros años de vida de la merluza se ve afectada por la coincidencia espacial con el Sistema Frontal Norpatagónico, caracterizado por una alta concentración de nutrientes, alta productividad y disponibilidad de alimento. Las condiciones físicas y la densidad larvaria en la zona de crianza afectaron el estado nutricional y la mortalidad de la merluza, principalmente por competencia por alimento o depredación. Se observó que la transición del hábitat pelágico al demersal en los juveniles se produce durante un período más extenso que el reconocido anteriormente para esta especie, lo que destaca la importancia de utilizar los registros acústicos para complementar la información de las redes de arrastre de fondo. Este es uno de los principales temas a desarrollar para estimar nuevos índices de reclutamiento de merluza argentina, junto con otras líneas de investigación propuestas para mejorar la evaluación del stock.
Aborto voluntario en Cuba: entre avances y desafíos
Authors: Esquenazi Borrego Arelys
Published: April 2023

Cuba fue el primer país de América Latina y el Caribe en despenalizar el aborto y crear normativas para que dicho procedimiento pudiera realizarse de forma legal, segura y gratuita. Ello formó parte de un conjunto de transformaciones, dirigidas a ampliar los derechos sexuales y reproductivos, impulsadas por la Revolución y las propias cubanas. El artículo se propone analizar el panorama actual del aborto voluntario en Cuba. La principal conclusión a la que se arriba es que a pesar de los avances alcanzados en estas más de seis décadas de la revolución, persisten un conjunto de desafíos desde el punto de vista jurídico y social. Más allá del aspecto legal, que se considera clave, son desafíos que paralelamente exigen el perfeccionamiento de procedimientos médicos y de programas/métodos más efectivos e integrales asociados a la educación sexual, la anticoncepción, entre otros. El método de investigación utilizado es la revisión bibliográfica.
Aborto Legal e Seguro para meninas brasileiras em tempos de barbárie: um diálogo com Debora Diniz
Authors: Boiteux Luciana
Published: April 2023

O texto de Debora Diniz intitulado: “A casa de uma menina: estupro, aborto e a pandemia de COVID-19 no Brasil” nos traz reflexões essenciais e sensíveis sobre o conhecido caso da menina de dez anos do Espírito Santo que engravidou vítima de um estupro de vulnerável (art. 217-A do Código Penal),[1] praticado por um parente dentro de casa e sua via-crúcis para ter acesso ao aborto legal e seguro. Em especial diante do conjunto de experiências terríveis que ela teve que passar até finalmente conseguir realizá-lo em um serviço localizado a mais de 1.480 km de sua casa. Isso garantiu a dignidade, o direito à vida e a um futuro, depois desse acesso ter-lhe sido negado no hospital universitário de seu estado sob a justificativa de “recusa consciente” pelos médicos.

 

[1] O crime de estupro de vulnerável, previsto no artigo 217-A do Código Penal prevê como crime: “Ter conjunção carnal ou praticar outro ato libidinoso com menor de 14 (catorze) anos”, ou seja, presume a violência nesses casos.
Hygienic assessment of 90Sr and 137Cs contamination of water and fish in the lakes of the head part of the peripheral zone of the East Ural radioactive trace
Authors: Smagin Andrej I.
Published: April 2023

Introduction. The article presents the results of studies of the specific activity of 90Sr and 137Cs in the water and fish of the Irtyash and Kazhakul lakes located in the peripheral zone of the head of the East Ural Radioactive trace in 2014-2017.
Materials and methods. Determination of the levels of specific 90Sr and 137Cs in the water and the body of the resource-forming species of Siberian roach (soroga, chebak) Rutilus rutilus lacustris (Linnaeus, 1758) from the studied lakes was carried out over the period of 2012–2017. The measurements were carried out using standardized methods adopted in in the Federal State Budgetary Institution of Health “Central Medical and Sanitary Unit No. 71 of the Federal Medical and Biological Agency of Russia” (FGBUZ TsMSCH No. 71 of the Federal Medical and Biological Agency of Russia) and the Southern Ural.
Results. The research was carried out over 2014 to 2017. Since the accident at the Mayak enterprise in the fall of 1957, the specific radioactivity of the water in the studied lakes was found to decrease. The concentration of 90Sr in the water of Irtyash lake was 0.019±0.008, and 137Cs – 0.028±0.009, and in Lake Kazhakul – 0.19±0.06 and 0.14±0.06, respectively. These values are much lower than the level of intervention according to NRB-99/2009.
The water of the lakes is used to meet household needs. The water of Lake Irtyash is used for drinking water supply of the city of Ozersk. The specific activity of the raw mass of a roach carcass from the Irtyash and Kazhakul lakes for the accumulation of 90Sr is 2.7± 1.7 and 64.5±19 and 137Cs – 1.68± 0.8 and 38±33.5Bq/kg, respectively. All the samples studied separately according to 90Sr and 137Cs had levels of radioactive contamination at or below the regulatory compliance indicator (SanPiN 2.3.2.1078–01). At the same time, taking into account the absolute extended uncertainty (with a coverage factor of k = 2) roach from Kazhakul lake has a significant excess of the limit level of radioactive contamination.
Limitations. Hydrochemical parameters of the aquatic environment in various reservoirs can vary significantly over time and affect the accumulation of radionuclides by hydrobionts. Therefore, the research results are relevant only for the research period. To obtain more reliable results, long-term comprehensive monitoring is necessary.
Conclusion. Over the past 60 years after the accident at the Mayak enterprise in 1957, the levels of radioactive contamination of water and fish in the studied lakes Irtyash and Kozhakul have decreased by more than 10 times. Calculation of doses of ionizing radiation for certain groups of the population of areas contaminated as a result of accidents, living near lakes, is a complex task, for which additional research is needed.
