Hak-hak perempuan dalam Islam
Authors: Farah Naila
Published: December 2020

Today's women's issues are still very important to pay attention to because women's rights have not been fully fulfilled. The marginalization of women's rights often stems from local religious and cultural beliefs. This is where the importance of the thinking of figures like Asghar Ali Engineer is reviewed in the present. This paper discusses the thoughts of Asghar Ali Engineer about liberation theology in the matter of women's rights in Islam. Asghar Ali Engineer in many of his works has offered various kinds of deconstruction of discourses. In the matter of women's rights in Islam, he presents his opinion on inheritance, wealth, testimony, the position of women in the family, polygamy and divorce which are considered as examples of inequality. With its hermeneutic interpretation, Asghar Engineering rejects the existence of a patriarchal concept that is inherent in the classical interpretation of the Quran, which is considered discriminatory against women. Then he applies the verses of the Quran into two, namely normative and contextual, with the hope that the verses of the Quran can be reinterpreted, so that it truly becomes a universal verses of â€œdas solenâ€ on one side and contextual verses of â€œdas seinâ€ on the other. Thus, the equality of men and women can be realized and gender-based justice can be manifested.

Authors: Borisova Tatyana Yurevna , Geraskin Petr Petrovich
Published: December 2020

The article focuses on studying the formation of secondary immunodeficiency in gobies in the northern and southern parts of the Russian sector of the Northern Caspian Sea. The study was based on a new approach to studying the immune system – the detection of a natural inhibitory factor in biological fluids. It has been shown that the level of secondary immunodeficiency is an integral indicator that expresses not only the state of the immune system, but also the physiological status of the studied fish and their adaptive capabilities. In the studied areas of the Northern Caspian Sea the worst results of secondary immunodeficiency were found in gobies caught in the waters of Small Zhemchuzhny Island and Bolshaya Zhemchuzhnaya Bank, the best results were registered off Kulalinskaya Bank. It has been stated that in the first decade of the 2000s the inhibition index in the water area of Maly Zhemchuzhny Island and Bolshaya Zhemchuzhnaya Bank was, on average, 1.2 times lower than in 2018. In addition, in the areas of Maly Zhemchuzhny Island and Kulalinskaya Bank fish without immunodeficiency were detected until 2002, the proportion of which decreased from year to year. It is assumed that the formation of immunodeficiency is associated with a long-term impact on bulls of flood waters of the Volga River, contaminated with toxic substances.

Authors: Salvatory Kalabamu Florence , Msengi George , Mkopi Namala
Published: December 2020

Introduction: There is an overwhelming increase of Non-Communicable Disease worldwide such as diabetes and cardiovascular diseases. Overweight and obesity are highly associated with development of these diseases. Unhealthy lifestyle such as excessive sugar, alcohol intake and lack of adequate physical activities has been associated with development of obesity. However, these risk factors are not well elucidated among adolescents in Tanzania. We conducted this survey to determine obesity, overweight, self-reported physical activities, and preferred foods among secondary school students in Kinondoni Municipal in Dar es salaam, Tanzania. Methods: A cross sectional descriptive survey was conducted among secondary school students at Kambangwa and Makumbusho secondary schools in Kinondoni municipal in Dar es Salaam city. A simple random sampling technique was used to select participating schools with systemic random selection procedure was used to select participants. A pre structured, self-administered questionnaire was used to collect demographic information from the participants. Anthropometric measurement for Body Mass Index (BMI) was done using standard tools. Interpretation of the findings was done using World Health Organization (WHO) standard charts for age and sex. Data were analysed using Statistical Package for Social Sciences (SPSS version 20; SPSS Inc., Chicago, US). Results: A total of 234 participants were enrolled in the study. A total of 204 (87.2%) of study participants reported to regularly participate in physical sports activities. Furthermore, Males reported to participate more in physical sports activities compared to females ( X2 (1) =8.13., p = 0.004). During sex-wise comparison, 30 (46.2%) of males reported to participate in sports once per week compared to 71 (51.5%) of females. Reported frequency was influenced by participants’ sex ( X2 (3) =16.4., p= 0.001). A total of 28 (12%) participants reported fruits as their favourite food. Food preference was influenced by the participants’ sex (X 2 (5) =13.1., p < 0.02). 32(47.7%) of males reported fresh fruits juice as their favourite drink compared to 106(63.5%) of females) while 6(9%) of males reported to prefer commercial industrial juice compared to 4 (2.4%) of females Conclusion: Obesity and overweight are prevalent among secondary school adolescents in Kinondoni Municipal, Dar es salaam. In addition, the magnitude of physical activities was below the recommended amount. Therefore, awareness campaigns and advocacy programs aiming at preventive measures against NCDs such as healthy eating behaviour and promotion of physical activities among adolescents should be given high priority.
Ethnocultural factors in virtual and “real” gender stereotypes
Authors: Sikevich Z. V. , Fedorova A. A.
Published: December 2020

The article presents a comparative study on collective perceptions in gender attitudes and marriage strategies approved by the representatives of the Russian ethnic group. The empirical basis for comparison combines obtrusive and unobtrusive methods. In 2014– 2015 we conducted a questionnaire survey among Russian residents of St. Petersburg (the sample was quoted by sex and age, it included 503 participants). Later, in 2017–2019, we performed a non-reactive analysis on the Russian communities in VKontakte network (sample was divided by value orientations, the total number of individual users included 1.051 million people). Big data analytics services, digital Ethnography methods and projective techniques helped us to answer the following questions: – What features does a “just Russian woman” and a “just Russian man” have in the collective consciousness? – What are the structural differences in these perceptions? – How are gender and marriage stereotypes manifested in the “real world” and in cyberspace? Thus, we obtained the conclusion that gendered patterns in both studies changed much more slowly than the models of the marital relationship. In both studies, the content of Russian women portrait was more detailed than the image of a Russian man. Russian social media users have demonstrated a commitment to the Patriarchal model, which was less evident in the questionnaire. In addition, the high level of radicalism and obvious religious values were the reason why women were more consistent with gender and marriage attitudes in the virtual environment.

Published: December 2020

Background

Venous thromboembolism is the second leading cause of death in cancer patients and its incidence seems underestimated. In addition, cancer patients have an increased risk of developing atrial fibrillation, which may be the first presentation of cancer itself. The primary aim of this study was to define the incidence of venous thromboembolism (VTE) and atrial fibrillation in a real-word series of advanced cancer patients.

Methods

We performed a retrospective single-institution study on patients diagnosed with stage IV solid neoplasia at the outpatient clinic of the Medical Oncology Unit (Spedali Civili Brescia, Italy), from January to December 2018.

Results

A total of 403 patients were enrolled, with a mean age at presentation of 63 years (range 18–85 years). A VTE was observed in 24% of cases, half of which occurred after diagnosis of metastatic neoplasia, with a median time of onset of 5.5 months (range 0–84). About 3% of patients developed atrial fibrillation after cancer diagnosis. In this patient series, no statistically significant differences were found when comparing Khorana and PROTECHT thromboembolic risk scores, both before and after the start of chemotherapy. Overall, about 25% of the patients received anticoagulant therapy; in most cases, the drug of choice was low-molecular-weight heparin (LMWH).

Conclusion

This study showed for cancer patients a considerably higher incidence of VTE and a comparable incidence of atrial fibrillation than reported in literature. Validated thromboembolic risk scores appear to be poorly predictive, and LMWH remains the most widely used anticoagulant drug.
The spatial pattern of selected extreme precipitation indices for Turkey (1975-2012)
Authors: Sarış Faize
Published: December 2020

This paper analyses extreme precipitation characteristics of Turkey based on selected WMO climate change indices. The indices – monthly total rainy days (RDays); monthly maximum 1-day precipitation (Rx1day); simple precipitation intensity index (SDII); and monthly count of days when total precipitation (represented by PRCP) exceeds 10 mm (R10mm) – were calculated for 98 stations for the 38-year overlapping period (1975–2012). Cluster analysis was applied to evaluate the spatial characterisation of the annual precipitation extremes. Four extreme precipitation clusters were detected. Cluster 1 corresponds spatially to Central and Eastern Anatolia and is identified with the lowest values of the indices, except rainy days. Cluster 2 is concentrated mainly on the west and south of Anatolia, and especially the coastal zone, and can be characterised with the lowest rainy days, and high and moderate values of other indices. These two clusters are the most prominent classes throughout the country, and include a total of 82 stations. Cluster 3 is clearly located in the Black Sea coastal zone in the north, and has high and moderate index values. Two stations on the north-east coast of the Black Sea region are identified as Cluster 4, which exhibits the highest values among all indices. The overall results reveal that winter months and October have the highest proportion of precipitation extremes in Turkey. The north-east part of the Black Sea region and Mediterranean coastal area from the south-west to the south-east are prone to frequent extreme precipitation events.

Published: December 2020

This study investigates brand equity dimensions and customer retention of the Nigerian telecommunications industry. Cross-sectional research design was adopted to survey 368 postpaid subscribers. The respondents were selected through multistage sampling techniques. The four dimensions of brand equity (brand awareness, brand association, perceived quality, and brand loyalty) were found to be correlated with one another and with overall brand equity. Similarly, the four dimensions were correlated to and significantly predicted customer retention. The study concluded that improvement of all the four dimensions of brand equity is indispensably vital to customer retention in the mobile telecom industry. The study recommended that telecom operator that is desirous of sustaining high brand notch in the marketplace should intensify their effort to improve on all the four dimensions of brand equity to enhance subscribers’ retention. Findings of this study fill important gaps and contribute to the body of literature related to brand equity dimensions and customer retention from customers’ perspective.

Проанализированы данные ежегодных геоботанических описаний сосняка сложного Pineta sylvestris composita (nemoro-boroherbosa), начатые после 45 лет заповедного режима и проводившиеся в течение 25 лет на постоянной пробной площади в Приокско-Террасном заповеднике (54.89o N, 37.56о E). Изменение экологических условий местообитания в ходе сукцессионной динамики растительного сообщества оценивалось по экологическим шкалам Д.Н. Цыганова, Г. Элленберга и Э. Ландольта. Характерный для исследуемого фитоценоза процесс смены пионерных видов древесного яруса (Pinus sylvestris L., Betula pendula Roth) на зональные эдификаторы хвойно-широколиственных лесов (Picea abies (L.) Karst., Tilia cordata Mill.) проявился в закономерном снижении общей освещенности под пологом древостоя, незначительном повышении влажности почвы. Выполненные оценки показывают рост богатства почвы, что объясняется изменениями в составе поверхностного опада в результате увеличения участия ели и липы в подросте. Вследствие действия комплекса факторов в травяно-кустарничковом ярусе увеличилось число стенобионтных видов, требовательных к богатству почвы, и одновременно с этим сохранили свое присутствие виды бедных местообитаний.

Published: December 2020

Background: Depending on the genetic mutation, mitochondrial hepatopathy has a variable presentation. Spontaneous recovery is a rare occurrence in these patients. However, complete recovery is possible in infants having t-RNA5-methylaminomethyl-2-thiouridylate methyl-transferase (TRMU) gene mutation.
Case presentation: A 53-day-old female child presented with hepatopathy and lactic acidosis. Genetic work up showed she has a mitochondrial respiratory chain disorder due to the TRMU gene mutation. Very few patients with isolated hepatic involvement have been described in the literature. We are reporting the first case from India of transient hepatopathy due to heterozygous TRMU gene mutation. Recovery was spontaneous at 4 months of age.
Conclusion: Complete recovery is possible in infants having TRMU mutation if they are supported through and survive the acute phase. The identification of TRMU mutation could impact clinical management.

Published: December 2020

Background. Mitochondrial uncoupling proteins (UCP) 1, 2 and 3 are members of the anion carrier protein family located in the inner mitochondrial membrane. There are various controversial reports on UCP genotypes and obesity in adults and children. This study aims to investigate the link between mostly studied UCP polymorphisms (UCP1-3826A/G, UCP2 Insertion/Deletion (Ins/Del) polymorphism of exon 8, and UCP3-55C/T Polymorphisms) and obesity in Turkish children. Furthermore, the relationships of UCP polymorphisms are also analyzed within the scope of metabolic parameters of obese children.
Methods. Molecular screening of the UCP1, UCP2, and UCP3 gene polymorphisms was carried out in 189 children aged 6 to 18 years, 102 of who had exogenous obesity (54 girls) and 87 of whom were healthy controls (48 girls). In the obese group, fasting lipids, glucose and insulin levels were measured. In 60 obese children, an oral glucose tolerance test (OGTT) was performed with 0, 30, 60, 90 and 120 minutes of sampling for plasma glucose and insulin levels.
Results. The frequency of UCP polymorphisms was similar in obese and non-obese children. In obese children, fasting lipids, glucose and insulin levels were not different among the UCP 1, 2 and 3 genotypes. While no relationship was found between the UCP 1 and 3 genotypes and glucose/insulin levels during OGTT, carriers of the Insertion allele with UCP2 Ins/Del polymorphism had significantly higher 30-minute insulin levels (p=0.018).
Conclusions. Polymorphisms of the UCP1-3826A/G, UCP2 Ins/Del, and UCP3-55C/T are not associated with obesity and related pathologies in Turkish children. However, the presence of the Ins allele of the UCP2 gene has been found to have an unfavorable influence on early insulin excursion after glucose loading.

Published: December 2020

Background. Our study aimed to compare the outcome of different therapeutic modalities for the management of children with Guillain-Barré syndrome (GBS) and to identify the associating risk factors that may affect the course and prognosis of the disease.
Methods. Our retrospective study compared the outcomes of different therapeutic regimens for patients with GBS who were admitted to Assiut University Children Hospital, Assiut, Egypt, from 2014 to 2016.
Results. The study included 50 patients diagnosed with GBS. Upper respiratory tract infection was the most prevalent preceding factor (66%). Acute inflammatory demyelinating polyneuropathy (AIDP) was the most prevalent type (80%). Regarding therapeutic modalities, 45 patients started with IVIG treatment, and five patients started plasmapheresis. Seventeen patients showed no improvement after two weeks of IVIG and received plasmapheresis as a sequential therapy. We found no patients who received plasmapheresis, followed by IVIG. Patients treated with plasmapheresis alone showed a significantly shorter duration of hospitalization and better outcomes in comparison to those treated with IVIG alone or with both modalities.
Conclusions. AIDP was the most common variety of GBS in our study. GBS patients who were treated with plasmapheresis had a better outcome with a short duration of hospitalization.

Published: December 2020

Background. Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders and has a big impact on the well-being of children. The disorder can lead to noticeable functional limitations for children and bio-ecological factors also contribute to symptoms of ADHD. We aimed to investigate the associations between ADHD symptoms and some related bio-ecological factors including serum ferritin, zinc levels and sensory processing in preschool-aged children.
Methods. Twenty-two children who had been referred to the division of Developmental Pediatrics because of ADHD symptoms and 22 participants from the general pediatric outpatient clinics were included in the study. The symptoms of ADHD were evaluated with Conners` Parent Rating Scale-Revised Short form. Complete blood count, serum ferritin and zinc levels were also evaluated. A blind occupational therapist implemented sensory processing measurements. The characteristics of each participant such as prematurity, perinatal complications, developmental practices and sociodemographic data were also considered.
Results. Sensory processing measurement analysis revealed that all Sensory Profile scores were significantly lower in the children with ADHD symptoms compared to the control group indicating that the child shows the behavior more than desired. The low level of zinc (p=0.026, OR=6.153, 95% CI= 1.247-30.362) and the presence of perinatal complications (p=0.045, OR=10.864, 95% CI=1.059-111.499) increased the risk of ADHD symptoms. We could not find an association for ferritin levels in our study.
Conclusions. The evaluation of zinc level and sensory profile parallel to other strategies can be recommended during the management of ADHD symptoms in preschool children.

Penelitian ini bertujuan untuk memahami model komunikasi persuasi yang terdapat pada saluran YouTube Kisah Tanah Jawa (KTJ). Masyarakat Indonesia dikenal sebagai masyarakat yang cenderung memercayai hal-hal yang bersifat metafisika. Sementara itu, KTJ hadir sebagai saluran Youtube yang bergerak dalam menginvestigasi kisah mistis dan mitos di pulau Jawa. Menjadi keunikan tersendiri karena KTJ yang pada dasarnya merupakan akun saluran Youtube, ternyata memiliki model komunikasi tersendiri dalam membentuk ideologi yang  bersifat metafisika. Hal tersebut tampak dari maraknya kehadiran laskar-laskar KTJ daerah di pulau Jawa yang secara sporadis bermisi serupa yakni menguak kisah legenda dan sejarah di masing-masing daerahnya. Melalui pemahaman Michael Heim dapat dipahami bahwa KTJ memiliki karakteristik virtual reality  sebagai upaya dalam mengomunikasikan ideologi cyber culture masyarakat konsumsi khususnya di Pulau Jawa yang meliputi networked communication, simulasi, artificial, telepresence, dan immersion.
Análise de discursiva e literatura surda
Authors: Silva Heron Ferreira da
Published: December 2020

RESUMO O estudo do discurso literário se justifica pela necessidade e importância de se compreender os textos de literatura surda, que têm cada vez mais circulado socialmente no espaço acadêmico. Com o intuito de pensar as relações próprias da abordagem de textos desta esfera, procedemos a uma pesquisa teórica sobre a Análise de Discurso de linha francesa, iniciada por Michel Pêcheux e ampliada por Eni Orlandi, no Brasil, e, selecionamos como nosso arquivo recortes do livro autobiográfico O Voo/Grito da Gaivota, de Emmanuelle Laborit, surda. Ler um texto de literatura é mergulhar em um mundo diferente e intrigante, quando nos remetemos mais precisamente à Literatura Surda, retomamos, em nosso imaginário social, a posição-sujeito surdo, posição historicamente negada, mas posição de escritor e produtor da sua própria literatura. A leitura do material permitiu-nos compreender como se dá o processo de subjetivação do sujeito surdo em meio a uma sociedade ouvintista, em que o discurso de normalização impõe sua constituição. Tal processo se fortalece pelo reconhecimento de Emmanuelle na posição de diversidade, enquanto surda, na/pela língua de sinais, sua possibilidade de ser sujeito se constrói a partir da própria língua.

Objectives:

To assess the vitamin D status among the study population and to determine the association between Vitamin D deficiency and dyslipidemia.

Materials and Methods:

This cross sectional study included medical undergraduates aged between 18-20 years with no major illness or medication history. Complete fasting lipid profile was measured by photometry method and biochemical estimation of serum 25-hydroxy 25(OH)D was done using automated chemiluminescent immunoassay. Vitamin D status and lipid profile parameters were compared using Pearson Chi-square test. P < 0.05 was considered as statistically significant. Descriptive statistics such as mean, standard deviation, and inferential statistics like Chi-square test were used.

Results:

96.6% were vitamin D deficient and 40% of the subjects were dyslipidemic. There was no significant association between Vitamin D status and Lipid profile.

Conclusion:

High prevalence of Vitamin D deficiency but no significant association between vitamin D deficiency and dyslipidemia.
To study the efficacy of zolpidem in inducing daytime sleep and maintaining mental alertness subsequent to awakening
Authors: Vasudev BN , Ravi R , Mukherjee M , Tripathy NK
Published: December 2020

Introduction:

In operational environment, naps in the daytime could help in maintaining alertness and hence performance. However, due to operational constraints and circadian effect, an aircrew may not get good quantity and quality sleep during the day, even though adequate sleep window is available. In such situations, zolpidem could be effectively utilized to induce sleep. This study intended to examine the beneficial effects of zolpidem 5 mg and 10 mg in inducing daytime sleep and maintaining mental alertness in the subsequent awake period.

Material and Methods:

In a double-blind, placebo-controlled, repetitive measure design, 20 healthy male volunteers were longitudinally evaluated for their mental alertness and subjective perception of quality of sleep, sleepiness, and fatigue for a period of 12 h following zolpidem-induced daytime sleep. In addition, feedback was obtained on known untoward effects of zolpidem.

Results:

Zolpidem, in doses of both 5 mg and 10 mg, could induce daytime sleep in all participants. Quality of sleep induced by zolpidem was similar to that of night sleep quality. With 5 mg zolpidem, the alertness was maintained soon after awake from daytime sleep, whereas participants perceived sleepiness for a period of 1–2 h with 10 mg zolpidem. Following awakening, there was a significant increase in the number of lapses with time in the placebo group, which was not found significant with administration of zolpidem. The occurrence of untoward effects with 10 mg zolpidem was more than 5 mg zolpidem.

Conclusion:

Zolpidem 5 mg and 10 mg were found to be effective in inducing daytime sleep and maintaining performance subsequent to arousal. The sleepiness following arousal as well as adverse effects was found to be more for zolpidem 10 mg as compared to 5 mg. A mandatory ground observation of minimum of 8 h should be ensured following intake of zolpidem before undertaking any flying duties.
