Authors: Tuncel Niray , Buğday Esna Betül
Published: June 2022

The COVID-19 pandemic has made significant differences in consumers' sustainable consumption behaviors and their attitudes toward environmental issues. After the global spread of the virus, a growing number of people became more aware of the environmental impact of their consumption habits, and their purchasing decisions shifted to favoring products and brands that place a higher value on environmental issues. Therefore, this chapter aims to introduce what the existing knowledge has presented about the impact of the COVID-19 pandemic on consumers' sustainable consumption practices and presents an overview of the existing literature. For this purpose, the current study focused on the recent research that addressed the changes in the sustainable consumption behaviors of consumers from different aspects, such as consumer spending habits, adopting a voluntarily simple life, consumption of energy and natural resources, the purchase, consumption, and use of environmentally friendly products and participating in sustainable practices.
Mathematics of the Circular Economics
Authors: Norouzi Nima
Published: June 2022

Based on the findings of economic studies on the consequences of industrialization in emerging economies, this study aims to evaluate rotational economy processes in the Middle East and North Africa (MENA) using a Shannon entropy algorithm. An entropy-based analysis was performed for 19 MENA countries in the period 2000-2020. The modeling process involves constructing a hybrid index that consists of a weighted sum of all the indices developed by an algorithm based on Shannon's entropy. The weight assigned to each index in the analysis measures the importance of each index involved in developing the composite index. The results are similar to the international balancing, which combines and confirms the precision and reliability of this method.
Would You Pay for the Environment?
Authors: Karapınar Kocağ Esra
Published: June 2022

Environmental degradation is a rising global concern. Many countries aim a sustainable development that could reduce the pressure on the environment. Macro-level actions are mostly investigated in the literature. However, micro-level components to ensure a sustainable future are very limited. This chapter argues that individuals as micro-level actors in the system are extremely important actors to stop the depletion of the nature and to help restoring it. Who is more supportive to protect the environment? What kind of factors influence this behaviour? This chapter aims to shed light on individual determinants of environmentally friendly preferences. To do so, the WVS was used, and findings indicate that gender and unemployment status have no significant effect. However, age, income level, and education level of individuals significantly influence preferences of individuals. Bearing in mind potential limitations, this chapter nevertheless acknowledges the importance of individual characteristics that can help protect the environment.

Authors: Samarakoon P. S. M. J. U. , Ganesan S. , Senarathne R. K. C. N. , Chandrasiri N. S.
Published: June 2022

Streptococcus pyogenes is a pathogen capable of causing a wide spectrum of diseases including pharyngitis and streptococcal toxic shock syndrome, with a range of complications and outcomes. Even though it is not an uncommon pathogen, reports of scarlet fever are scarce in Sri Lanka. We describe a case of scarlet fever in a seven-year-old boy with typical features. The child presented with high fever, body aches, vomiting, loss of appetite and a rash and developed pharyngitis and a strawberry tongue during the ward stay. A pure growth of group A Streptococcus was isolated from a throat swab taken on admission. He improved with appropriate treatment and recovered without complications. The importance of throat swab culture and clinical correlation is illustrated in this case report.

Authors: Bhosale Neha M. , Arakeri Surekha U. , Reddy Anil K. , Mudanur Subhashchandra R.
Published: June 2022

Background:

Abnormal uterine bleeding (AUB) is one of the most common problems encountered in gynecological practice. Various benign and malignant disorders of the endometrial tissue show vascular changes such as congestion, dilatation, and vessel wall irregularities.

Aim:

To evaluate the vascular morphometry of the endometrial tissue in AUB.

Materials and Methods:

A descriptive cross-sectional study of the endometrial tissue in patients presented with AUB was undertaken for vascular morphometric analysis. Histopathological processing of the endometrial tissue samples was done as per the standard format, and the slides were evaluated for vascular morphometry.

Results:

Out of 150 cases of endometrial tissue in patients presented with AUB, 80 cases were reported as proliferative phase, 41 as secretory phase, 15 as disordered proliferative endometrium, 6 as atrophic phase endometrium, and 4 each of endometrial hyperplasia without atypia and endometrial carcinoma. An average number of endometrial blood vessels and large-sized blood vessels were more in endometrial carcinoma and endometrial hyperplasia without atypia as compared to proliferative phase, secretory phase, atrophic endometrium, and disordered proliferative endometrium. Vessel shape irregularities and vascular congestion were observed in all the cases of atrophic endometrium, endometrial carcinoma, and endometrial hyperplasia without atypia. Endometrial carcinoma showed severe dilatation of the endometrial blood vessels.

Conclusion:

Vascular morphometry changes were noted in endometrial hyperplasia, endometrial carcinoma, disordered proliferative endometrium, and atrophic phase endometrium. These findings suggest that studies or trials related to anti-angiogenic therapy may help to plan anti-angiogenic therapy in patients with AUB.

Authors: Singh Swarndeep , Saini Romil , Sagar Rajesh
Published: June 2022

Background:

Media plays an important role in creating awareness and shaping public opinion about child sexual abuse (CSA). Research suggests that sensible media reportage on CSA is important for positive impacts of media. However, most of the studies assessing the quality of CSA news reports are from western countries.

Aim:

To systematically assess the pattern of online news media reportage of CSA in India.

Methodology:

A total of 149 news reports on the topic of CSA in India, published online over a one-year period were analyzed. Framing of CSA and other news media characteristics were evaluated.

Results:

Framing of CSA was episodic in majority of news reports, with criminal-justice system-related details about individual cases mentioned in about 90% reports. Further, more than two-third news reports did not mention possible causes or reasons of CSA, and possible steps that people could take to prevent CSA. About one-fifth of news reports provided statistics, research findings, or correct information to dispel myths or wrong public stereotypes about CSA. Inclusion of child helpline or contact information of any child welfare/support services was missing in most of the news reports.

Conclusion:

This is the first study to systematically assess the quality of news media reports on CSA in India. It provides valuable baseline information about existing media practices and helps in identifying areas for further improvement of media reporting on CSA. There is a need to conduct regular workshops with media professionals to provide them adequate training and support for improving media reporting of CSA.

Published: June 2022

Background:

The study aimed to perform a cross-sectional comparative assessment of the content and quality of information available on the treatment of depression over websites in English and Hindi language.

Materials and Methods:

We screened the first 50 links obtained on searching for depression treatment on Google, and selected 72 (44 in English; 28 in Hindi) websites. They were evaluated for coverage of different aspects of depression, quality of treatments mentioned, esthetics, and interactivity.

Results:

A significantly lesser number of Hindi websites discussed the minimum duration of treatment needed for a depressive episode (36% vs. 79%), possible side effects of treatment (18% vs. 77%), discussed suicidality in depression explicitly (25% vs. 57%), or recommended consultation with a mental health professional (11% vs. 43%). English websites more commonly mentioned psychotherapy (86% vs. 64%), electroconvulsive therapy (64% vs. 21%), and social support measures (59% vs. 32%) for depression treatment. Whereas, Hindi websites more commonly mentioned Ayurvedic/herbal medicines (46% vs. 16%), and yoga (29% vs. 4%) for treatment. Lastly, the esthetics score for English websites was significantly higher than for Hindi websites. A significantly greater number of Hindi websites were owned by commercial entities.

Conclusion:

This is the first study to systematically compare online information on depression treatment in English and Hindi language websites, and identify areas for further improvement in the overall quality of online information in Hindi. There is a need for the creation of credible and accessible online resources in regional languages like Hindi for the promotion of depression literacy among the general public by government and non-profit professional organizations.

Authors: Nair Geethu G. , Feroze M
Published: June 2022

Context:

Multiple Choice Questions (MCQs) are one of the commonly used assessment tools in the field of medical education. A few initiatives have been made to use MCQ tests during classes as a mode of test-enhanced learning. However, there is a lack of enough scientific information regarding the use of MCQs as a learning enhancer.

Aims:

The present study has been undertaken to analyze the effectiveness of MCQ discussion as a learning tool.

Methodology:

The study was conducted in a Government Medical College in Kerala among Phase 2 MBBS students. They were divided into study and control groups of 61 students each. Online lecture classes were conducted for both groups on six topics of Pathology. For the study group, an additional MCQ discussion was done towards the end of the lecture class. Post-test was conducted on day 1 and after 2 weeks. A questionnaire was given to assess the attitude of students. Scores obtained in the post-tests were used to test the significance.

Results:

There was a significant difference in the mean score obtained between control and study groups in the post-test conducted on the same day suggesting that the MCQ discussion conducted at the end of the lecture class has added benefit (P value = 0.04). There was no significant improvement in academic performance when an assessment was made after 2 weeks (P value = 0.59). More than 80% of students showed a positive perception of this method.

Conclusion:

MCQ supplementation towards the end of the didactic lecture class is an effective teaching-learning method. Students also express a very positive attitude towards it. MCQs can be considered not only as an assessment tool but as a learning enhancer also.

Published: June 2022

ABSTRACT

Introduction:

Low back pain is one of the leading causes of disease burden globally. Matrix Rhythm Therapy (MRT) is based on rhythmic micro-oscillations of muscle tissue by the action of mechano-magnetic alternating fields. Pilates exercises have been shown to be helpful in low back pain. This study was conducted to compare the effects of MRT and Pilates exercises on chronic low back pain, lumbar flexibility, functional impairments, and pelvic inclination in chronic low back pain.

Materials and Methods:

Ethical clearance was obtained by ethical committee of Dr. D. Y. Patil Physiotherapy, Pimpri, Pune. 50 patients diagnosed with chronic low back pain were selected as per inclusion criteria after taking informed consent. Patients were randomly allocated to two groups. Group A (n = 25) received MRT. Group B (n = 25) were given Pilates exercise. Both groups received treatment thrice a week for two weeks. Duration of 45 min. Outcome measures were assessed for both groups at the beginning and end of the study. Outcome measures included Numerical Pain Rating Scale for pain, Modified-modified schober’s test for lumbar flexibility, pelvic inclination using an inclinometer, and Oswestry Low Back Disabaility Questionnaire for functional impairments. Data were analysed using Winpepi.

Results:

For all outcome measures, a highly significant improvement (p < 0.001) was seen in Group A, a significant improvement (p < 0.005) was seen in group B.

Discussion:

Pain, restricted movements, reduced flexibility, and pelvic inclination are the consequences of systemic and local disturbances in the logistics of the living processes due to chronic pain in low back region. MRT and Pilates, both individually are effective in treating the same.

Conclusion:

Both Groups showed significant improvements in patients with CLBP. However, the findings in MRT group highly statistically significant.

ABSTRACT

The orthognathic surgery plays an important role in achieving a pleasant-sounding dental, skeletal, and soft tissue which in turn helps an individual with jaw divergences to have function efficiency, aesthetic harmony, and structural balance. Pre-treatment profile photographs of the subjects were taken and morphed forward and backward, in 2 mm steps, until severely prognathic or retrognathic, respectively, to get class III and class II skeletal relation was acquired and the images were labeled from 1 to 5. The morphed profile photos were then camouflaged using Adobe Photoshop CS (v. 5.1) to generate silhouette images. The images were evaluated by three groups of assessors which includes orthodontists, oral surgeons, and laypersons. There was a statistically significant difference between oral surgeons, orthodontists, and laypersons in scoring class II (P < 0.001) for scoring adult females but no significance in rating adult males. There was a statistically significant difference between oral surgeons, orthodontists, and laypersons in scoring class III (P < 0.001) for scoring adult males and females. No difference was observed between scores when evaluated differently with the use of silhouettes or photos.
Exploring the unknown: The work of Louis Nirenberg on partial differential equations
Authors: Rivière Tristan
Published: June 2022

Partial differential equations are central objects in the mathematical modeling of natural and social sciences (sound propagation, heat diffusion, thermodynamics, electromagnetism, elasticity, fluid dynamics, quantum mechanics, population growth, finance, etc.). They were for a long time restricted only to the study of natural phenomena or questions pertaining to geometry, before becoming over the course of time, and especially in the last century, a field in itself.

The second half of the 20th century was the “golden age” of the exploration of partial differential equations from a theoretical perspective. Louis Nirenberg, starting in the early 1950s, played a major role in the growth of this fundamental area of human knowledge and his name is associated with many of the milestones in the study of PDEs.

Louis Nirenberg passed away in January 2020 and his memory as a mathematician and colleague is a special invitation to review the development of the field of PDEs through the work of its leading pioneers.

Renewable Energy Technologies in the Global South: Sub-Saharan Africa Trends and Perspectives
Authors:   Department of Mechanical Engineering, Institute for Systems Science, Durban University of Technology, Durban, South Africa, Ebhota Williams S. , Tabakov Pavel Y.
Published: June 2022

Sub Saharan Africa (SSA) and other parts of the Global South are richly endowed with renewable energy resources (RERs) that are grossly untapped. The integration of these resources, such as hydro, wind, solar, and biomass will facilitate the desired net zero-CO2-emissions economy. If these RERs are adequately harnessed, the perennial power supply challenges in the region will be resolved, and the negative power supply narrative changed. Presently, a greater percentage of the population without access to electricity live in the Global South with SSA having the highest share. This inadequacy has been attributed to many factors, which include lack of connection to the national grid; lack of adequate technical capacities to design and manufacture efficient power generation and transmission components and systems; insufficient funds; unreliable, limited, and poor energy data. A comprehensive study of the renewable energy potential (REP) and technologies in the Global South is imperative to the management, regulation, and policies concerning energy, in this era of energy transition (ET). This study presents - a summary of REP of SSA; statistical analysis of the proposed and installed RE capacity across the region; and discussion on the pressing need for renewable energy integration (REI) to mitigate climate change. In addition, to develop RE schemes to facilitate greater access to clean, affordable, and adequate energy supply. Actualization of the integration of RERs into the national portfolio will promote CO2 reduction and improve the socio-economic benefits to the populace in both rural and urban areas of SSA and the Global South generally.

Published: June 2022

In today’s context, there is a tremendous potential for the design of smart nanomaterials of carbon origin for multi-dimensional applications. The role-play of precursor is significant in the design of nanometric carbon materials apart from other experimental parameters. Correlation of the synthetic methodology, the microstructure of the product helps to tune and widen the applications aspect. The present study aimed to tune the simple ketose (reducing monosaccharide) of fructose to functionalize (with O, N, and S atoms) carbon layers, microspheres of carbon, to optimize the experimental conditions, and to establish the mechanism involved in the process. The study further explored the catalytic ability of the carbon samples in the degradation of thiazine and xanthene-based textile dyes and the sensing of heavy metal ions of chromium and copper. A simple hydrothermal process, fructose as a precursor, alkaline pH, and appropriate calcination temperature provided micro and nanostructures of carbon viz. carbon microspheres (CMs), graphene oxide (GO), sulfur doped graphene oxide (S-GO), and nitrogen-doped reduced graphene oxide (N-rGO). In this study a simple mechanism for the conversion process is suggested. Further, the results of the preliminary screening study on the catalytic ability of the sulfur and nitrogen-doped graphene samples in the presence of UV and Visible light upon the degradation of methylene blue (MB), methyl orange (MO), Rhodamine-B (Rh-B) dyes were satisfactory. The adsorbent and the ion exchange capacity of the carbon microspheres were found to be excellent. The results of the study will contribute positively to the treatment and management of industrial wastewater.

Authors: Suganya M. , Manimegalai K.
Published: June 2022

Order Orthoptera is one of the largest and most important invertebrate groups for environmental monitoring and assessment. Orthoptera faunal composition was carried out at Bharathi Park, Coimbatore, Tamil Nadu, India to evaluate the present status of various species. PAST software was used to perform various statistical analyses to estimate the Orthoptera composition. Overall, 334 individuals belonging to 22 species, 19 genera, 17 tribes under 10 subfamilies, and four families of Orthoptera were recorded. Species richness (59.09%) and species abundance (70.06%) were recorded highest in the Acrididae family followed by Pyrgomorphidae, Tettigoniidae, and Gryllidae. Oedipodinae was the most species-rich (27.27%) and the most abundant subfamily, accounting for 30.24% of the total collected individuals. During the study period, 10 dominant, five intermediate dominance, four incidental, and three rare species were observed. Among these, Spathosternum prasiniferum was found to be the most dominant species (D=18.26) and the least dominant (D = 0.6) species was Euconocephalus pallidus. Based on the principal component analysis, the distribution of species along with the first two PCs (PC1= 33.87% and PC2=28.68%) accounted for the highest variance of the total variances. Cluster analysis showed that Acrotylus humbertianus and Teleogryllus mitratus, Conocephalus maculates and Gryllus bimaculatus Orthopterans were similar to each other. The value of the Shannon diversity index (2.27), Simpson index (0.87), Margalef index (2.2), and α-diversity (5.75) were higher in Acrididae when compared with other families. Value of Evenness (0.93) was highest in Gryllidae. Statistical analysis infers that the richness and abundance percentage of Orthopterans significantly varied between species to species and family to family.

Published: June 2022

Kamu yönetimi etiği, kendi başına kamu yönetimi disiplini kapsamında sıklıkla tartışılan bir alanı oluşturmaktadır. Küreselleşme hareketleri ile birlikte 1980’lerden itibaren kamu yönetimine yapılan yeniliklerde kamu yönetimi etiği konusu, ülkelerce büyük ilgi ile karşılanmıştır. Ülkemizde de önemli bir yere sahip olan etik konusu, yeni kamu yönetimi anlayışı bağlamında niteliksel olarak gelişim sağlamıştır. Kamu yönetiminde iyi yönetimi sağlayabilmek için etkinlik ve verimliliği yakalama noktasında etik kurallara ihtiyaç duyulmaktadır. Bu çalışmada, bahsi geçen etik ilke ve kurallar ile yeni kamu yönetimi anlayışının ilkelerini kamu yönetimine entegre eden ülkelerin, etik dışı davranışlara ve yozlaşmalara daha az rastlayacağı veya bu olumsuz davranışların engellenmesinde daha iyi sonuç alacağı öngörülmektedir. Çalışmada, vatandaşın devlete olan güveninin artmasında, kaliteli hizmet beklentisinin karşılanmasında ve kamu yönetiminin verimli bir şekilde işleyişinin sağlanmasında etkili olan etmenlerden olan etik kavramının, kurum kültürünü oluşturan bir konu haline gelmesi gerektiği işlenmiştir. Bu bağlamda kurumsal hale gelen Kamu Görevlileri Etik Kurulu’nun yapısal ve işlevsel faaliyetleri değerlendirilerek yeni kamu yönetimi anlayışının ilkeleri doğrultusunda olumlu ve eksik yönleri analiz edilmiştir.

Squamous cell carcinoma (SCC) is a malignant epithelial tumor of skin. All species of animals are vulnerable to SCC and, sheep are very rarely developing this type of skin carcinoma. The purpose of this report was to describe unusual mammary lobe localization of SCC showing a great resemblance to the mammary tumor according to its gross and clinical examinations. The patient was brought to obstetrics and gynaecology department and, tumoral tissue was totally extirpated with a suspicion of mammary tumor. The diagnosis made as differentiated squamous cell carcinoma originated from the skin surface and invading through the dermis and subcutis but mammary gland parenchyma was remained intact. There are only few reports of SCC cases belonging to the skin of the mammary area in sheep. Therefore, it is thought that this case will make a scientific contribution with its originality and rarity.

Published: June 2022

Günümüzde kültürel belleğin somut kalıntılarından biri olarak kabul edilen kibrit ve kutusu, temel tüketim malı olması nedeniyle 2000’lerin başına dek Türkiye’de gündelik yaşamın önemli bir parçası olmuştur. Teknik işlevi yanısıra, kutular üzerinde yer alan grafik öğeler aracılığıyla toplumu bilinçlendirmeyi ve farkındalık yaratmayı amaçlayan sosyal mesajların aktarılması için bir araç olarak kullanılmıştır. Bu çalışmanın amacı, kibrit kutusunun kamu kurum/kuruluşları ve dernek/vakıf gibi kâr amacı gütmeyen sivil toplum kuruluşları tarafından kullanılan bir kitle iletişim aracı olarak fonksiyonel önemini ortaya koymaktır. Çalışma kapsamında Haluk Sağlamtimur Kibrit Kutusu Koleksiyonun bir kısmını oluşturan sosyal mesaj içerikli örnekler temalarına göre 21 ana başlık altında sınıflandırılmış ve sağlık konulu sosyal mesaj içeren 9 ana başlıkta yer alan 116 örnek içerik analizi ile incelenmiştir. İmal tarihi belli olmayan örneklere, dönemin sosyo politik ortamı değerlendirilerek ve efemera çalışmalarına yönelik kaynaklar incelenerek, makalenin yazarları tarafından imal tarihi aralığı atanmıştır. Nitel analizler sonucunda elde edilen tablodaki veriler tema, marka, ilgili kurum/kuruluş, tarih, mesaj iletim yöntemi ve kutu üstündeki mesaj sayısı açısından frekans analizine tabi tutulmuştur. İncelemeler sonucunda, örneklem çerçevesinde en sık ele alınan sağlık temasının “İşçi Sağlığı” olduğu, sağlık konusuna yönelik en kapsamlı mesajın “Thalassemi ile Savaşım” kibrit serisiyle hedef kitleye ulaştırıldığı, en çok kullanılan mesaj iletim yönteminin piktogramla desteklenmiş slogan olduğu, bir kutu üstünde en çok mesajın 3 farlı mesaj içeren “Organ Bağışı” konulu örnek aracılığıyla iletildiği, sağlık konulu sosyal mesajların yoğunlaştığı tarih aralığının 1980’lerin başları ile 1990’ların ortaları olduğu ve kibrit kutularının en çok Bakanlıklar tarafından sosyal mesaj iletmek amacıyla kullanıldığı tespit edilmiştir.

Published: June 2022

We report a preliminary study of stress corrosion cracking (SCC) of a 13Cr-5Ni-2Mo martensitic stainless steel (UNS S41426), 110 ksi grade in methanol at 82°C. SCC was predominantly intergranular, although transgranular cracking also occurred at low chloride solutions. SCC was eliminated by the absence of oxygen and/or the presence of water. The presence of copper exacerbated the cracking slightly.

Published: June 2022

Background

This study aimed to investigate English teachers’ self-efficacy for student engagement, classroom management, instructional strategies and literacy instruction, as well as to discover teacher stress and job satisfaction can play a role in interfering their occupational health (in terms of self-efficacy). In addition, this is one of the first studies to understand the differences in self-efficacy among pre-service, novice and experienced in-service teachers in a Chinese society, where English is positioned as a foreign language.

Participants and procedure

271 English teachers (90 pre-service, 181 in-service) with mean teaching experience of 5.57 months for per-service, and 98.51 months for in-service were participated in this quantitative research study, as the targets were not be able to approach randomly, the English teachers were approaching individually though referral sampling, informing that the purpose of the study and receive their consent.

Results

It discovered both pre-service and novice in-service teachers posses lowest self-efficacy. Moreover, teachers’ stress from classroom predicted their self-efficacy for student engagement and classroom management negatively. On the other hand, teachers’ job satisfaction predicts their self-efficacy for student engagement, instructional strategies and literacy instruction positively.

Conclusions

Implications (based on the findings) are discussed in order to provide insights for for schools and education departments to strengthen the teachers’ capability of teaching and their occupational health.

Authors: Yilmaz Pinar Diydem , Kadiyoran Cengiz , Horasanli Jule
Published: June 2022

Purpose

The aim of this study was to investigate whether there is a relationship between adenomyosis and nabothian cyst (NC) in a large patient series.

Material and methods

The patient’s data were scanned retrospectively and patients with a junctional zone thickness of 12 mm and above on magnetic resonance imaging were accepted as group adenomyosis (group A). Patients with a junctional zone thickness of less than 12 mm were not admitted as adenomyosis (control group). Both groups were compared for NC.

Results

In group A, 176 (69.8%) patients had NC (n = 250), while in the control group (n = 202), 57 (28.2%) patients had NC. NC was significantly higher in group A than in the control group (p < 0.001).

Conclusions

The aetiology of NC is still unclear. According to our results, similar factors may affect adenomyosis and NC aetiopathogenesis.
