Promoter activity analysis and transcriptional profile of Ginkgo biloba 1-Deoxy-D- Xylulose 5-Phosphate reductoisomerase gene (GbDXR) under abiotic stresses
Authors: YUAN Honghui , LI Linling , LI Li , CHENG Hua , CHENG Shuiyuan
Published: March 2022

Terpene trilactones (TTL) is a pharmacological ingredient in Ginkgo biloba and its content has become one of the key indices for medicinal value evaluation of ginkgo. 1-Deoxy-D-xylulose 5-phosphate reductoisomerase (DXR) catalyzes the first step specific for isopentenyl diphosphate production in methylerythritol phosphate pathway, which provide the basic structure required for TTLs biosynthesis. To understand the mechanism controlling the GbDXR gene expression, the GbDXR promoter sequence was isolated and subjected to transient expression with the green fluorescent protein (GFP) in tobacco plants. Characteristic analysis revealed various cis-acting elements that related to light-regulated transcription, hormone signaling (auxin, ethylene), adversity stress and defense signaling (heat/dehydration stress) in the GbDXR promoter region. In transient expression assay, deletion of different portions of the upstream GbDXR promoter identified that the promoter region -3230bp to -865bp conserve the positive regulation function, which could promote the expression of GFP in the cytoplasm of tobacco leaf epidermal cells. The regulation function of the promoter region -865bp to -262bp remained to be elucidated. EMSA analysis suggested possible interactions of GbERF10 and GbERF17 with the ERF-binding elements in the upstream of GbDXR promoter. For abiotic stresses treatment, the expression of GbDXR gene could be significantly induced by UV-B and drought stress. In general, the GbDXR gene expressed differently in different ginkgo tissues but exhibited the highest transcriptional level in the root, with the maximum TTLs content simultaneously. The positive relationship between gene expression level and TTLs content indicated that the GbDXR is responsible for TTLs biosynthesis in G. biloba.

Fungi are the most important phytopathogens that cause yield losses. The mycotoxins released by fungi cause spoilage of stored food consumed by humans and feed supplied to animals. Fungi-antagonistic microbes are gaining attention as potential biocontrol agents (BCAs). This study was designed to isolate bacterial isolates from different crops and evaluate their in vitro antifungal assay against three phytopathogens, plant growth promoting (PGP) characteristics, molecular identification, and in vivo efficiency against the most devastating phytopathogenic fungus Fusarium oxysporum Schltdl. In the in vitro experiment, the 3 isolates BA, GL-1, and 5a out of 360 isolates showed more than 60% inhibitory activity against the selected fungi in this study. On the basis of 16S rRNA sequencing and phylogenetic analysis, BA isolate was identified as Bacillus velezensis. All three isolates produced indole acetic acid (IAA), hydrogen cyanide (HCN), and cellulase enzymes, while the BA and GL-1 isolates also produced siderophores and the BA isolate also produced ammonia. BA was selected on basis of not only Biocontrol efficacy but also maximum PGPR activity compared to GL-1 and 5a. In vivo assay, the isolate BA showed a significant decrease in disease severity caused by Fusarium oxysporum by 64.97% after 100 days of inoculation on wheat (FD-08) seedlings in a greenhouse assay and enhanced the shoot root height, fresh and dry mass. The wide-ranging antagonistic action of Bacillus velezensis isolated from the phyllosphere of wheat crops showed promising fungicidal and plant growth-promoting capabilities, suggesting it can be used as a biofungicide.

Published: March 2022

Crabapples (Malus spp.) are frequently used as ornamental trees. However, selections differ in decorative impact through blossoming and fruiting traits, growth habit, disease tolerance, ecological adaptability and fruit litter, so that there can be other valuable benefits. The aim of the present investigation was to determine morphometric characteristics of flowers, fruits and seeds within 15 different genotypes of crabapples studied at M.M. Grishko National Botanical Garden in Kyiv, Ukraine. Their main morphometric parameters were as follows: the highest number of flowers in the inflorescence was recorded within trees of ‘Professor Sprenger’ with 5.78 flowers, whereas the corolla was mostly decorative for ‘Royalty’ cultivar, with 5.7 petals; fruit weight varied from 1.49 g (‘Adirondak’) to 20.56 g (‘Era’), length from 12.87 mm (‘Van Ezeltine’) to 25.11 mm (‘Ola’), diameter from 12.0 mm (‘Batterball’) to 26.74 mm (‘Rayka Rozeva’), fruits number 1.0 (‘Era’) to 5.5 (‘Evereste’). The relationships between flowers, fruit and seed traits, accounting 16 traits and 15 cultivars investigated was highlighted by Pearson correlation and were clustered by unweighted pair group method with arithmetic mean (UPGMA). The variability observed in the apple crab genotypes offers the possibility to choose and use some valuable ornamental cultivars for the beautification of the landscape, as well as for possible future Malus breeding projects.

Published: March 2022

Microfungi are one of the important microbial groups in agriculture due to their positive, mutualistic and negative effect on plant growth and productivity. The roles of fungi extend from organic matter decomposition and mineral cycling to plant growth promotion. Considering these indispensable roles of this microbial group, the present research was undertaken to investigate the indigenous dominant microfungi in tea garden soils of Mokokchung district, Nagaland in India. The dominant microfungi were screened for their phosphate solubilization activity in PVK agar medium using tri-calcium phosphate as the sole phosphate source. Microfungal isolates showed significant differences in culture plates as well as microscopic studies. A total of 110 fungal isolates under 19 genera were identified in the present study. Among the soil microfungi, Aspergillus, Penicillium and Trichoderma were found to dominate the studied tea garden soils. The highest phosphate solubilization activities were observed for species under Aspergillus (1.95 cm to 1.71 cm) followed by Penicillium (1.57 cm to 1.18 cm) and Trichoderma species (1.13 cm to1.06 cm). The present study offers a glimpse of indigenous microfungi as well as provide information on the dominant microfungi in tea garden soils of Mokokchung district, Nagaland and hence, will aid and expand knowledge on indigenous fungi and their various roles. Also, the applications of potent phosphate-solubilizers isolated in this study can be a future source of biofertilizers consortium for tea and other plants.

The pathogenicity of the root-knot nematodes Meloidogyne arenaria, M. incognita and M. javanica on spinach cvs. ‘Balady’, ‘Barkly’, ‘Orient’, ‘Pacific’ and ‘Solanicy’, Swiss chard cvs. ‘Balady’ and ‘Ford Hook’, and table beet cvs. ‘Asgro Wonder’, ‘Balady’, ‘Detroit Dark’ and ‘Detroit Spainal’ was determined in several greenhouse tests. The results show that the tested chenopodiaceous plant cultivars were either susceptible or highly susceptible to the tested root-knot nematode species except spinach cv. ‘Pacific’ and table beet cv. ‘Asgro Wonder’ which exhibited moderately susceptible reaction to M. arenaria and M. javanica. In a separate control experiment, the pathogenicity of M. incognita on spinach cv. ‘Balady’ was studied in a greenhouse experiment. Soil treatments with dried plant materials of Monterey cypress, Brazil pepper- tree, lime and China tree induced great reductions (81.4-91.8%) in the numbers of root galls and egg masses of M. incognita on infected spinach plants. On the other hand, treatments with plant materials of blue gum tree, California pepper - tree, lantana and pomegranate gave 49.8-69.3% reduction of root galls and egg masses of M. incognita on infected spinach plants.

Authors: ŞALVARCI Simge
Published: March 2022

Values such as historical and cultural heritage and natural beauties belonging to a destination are very important in terms of identity creation and marketing of destinations. The attractiveness of these values, which are in the tourism sector, which is developing with a rapidly increasing momentum today, makes great contributions to the destinations. In addition, effective destination marketing provides an economic contribution to the region. In this context, Turkey, which is an important touristic destination with its rich tourism diversity, has important cultural routes. In the study, cultural routes in Turkey are examined in terms of political, economic, social and technological possibilities with PEST Analysis. According to the results of the evaluation, it has been determined that Turkey has a great potential in terms of cultural routes where millions of visitors walk every year in the world, but sufficient steps have not been taken in terms of tourism and destination marketing. In addition, it was concluded that the routes could not be protected due to the inadequacy of legal regulations and cooperation projects could not be made between the regions, and various suggestions were presented in this direction.

Published: March 2022

Developing Nations are subject to amplified challenges in terms of the integration of technology, and the exposure to non-domestic opportunism from larger neighboring economies. These challenges are recognizable as asymmetrical differences between what is seen as the normative list of critical infrastructures, and the specialisms that can dominate an emerging economy with early maturity technology networks. This paper discusses the case of Bhutan and demonstrates the need for strengthened approaches to trusted networks to ensure the reliability and continuity of the Nation's critical infrastructures. The paper also links the importance of trusted information sharing networks as part of an overarching technology strategy that protects the Gross National Happiness of the nation.
Selective Recognition of Kanamycin via Molecularly Imprinted Nanosensor
Authors: SARİ Esma
Published: March 2022

Herein, the molecular recognition sites on the surface of the chip were created by the molecular imprinting method to produce the surface plasmon resonance (SPR) based nanosensor for the real-time kanamycin (KAN) detection. Firstly, kanamycin imprinted nanofilm, which has specific recognition cavities for kanamycin were synthesized by in-situ radical polymerization. Fabricated nanofilm for the detection of kanamycin was characterized with FTIR, ellipsometer, and atomic force microscope by the means of structurally and morphologically. The mean thickness values were determined for the imprinted and non-imprinted nanofilms as 102.4±3.1 nm and 101.8±4.7, respectively. The sensitivity performance of imprinted nanosensor was investigated by using the KAN solutions at different concentrations (25-200 ng/mL). The refractive index and the KAN concentration were found to be in perfect agreement with a regression coefficient (R2, 0.992). The detection limit was calculated as 0.40±0.05 ng/mL by using the equation in the calibration curve. The response of imprinted and nonimprinted nanosensors towards the chemical analogs of KAN (NEO and SPM) were investigated to prove the selectivity of KAN imprinted nanosensors. The reusability performance of imprinted nanosensor was investigated by spiking 25 ng/mL KAN solution with three replicates. When the kinetic analyzes were examined, high sensitivity real-time kanamycin analysis was performed at very low concentrations with good reusability.

Published: March 2022

Subway lines are responsible for 20% of the total passenger traffic in Tehran. Particulate matter is one of the most important major pollutants in subway stations and increasing their concentration leads to numerous health consequences for passengers and subway employees. This study aims to investigate the concentration of PM10 and PM2.5 in four underground metro stations and compare them with the concentration of these particles in the open air. Seasonal sampling (April 2018 - April 2019) of particulate matters was conducted in the middle months of all four seasons for one week in the middle months of each season at peak traffic times from 8am to 12am, at three locations (entrance, middle, and exit in each station) and also at outside ambient of each station. The results are then compared with the relevant standards. The main sources of suspended particulate matter in the underground subway stations were due to passenger traffic, train piston pressure, floor cleaning, maintenance operations, wheel-rail wear and braking, and the performance of the ventilation system in the subway station. The results of the monitoring measurements in this study showed that the annual average concentrations of PM10 and PM2.5 in the four underground subway stations were 68 μg/m3 and 47 μg/m3 and in the outdoor ambient around these stations were 42 and 29 μg/m3, respectively. Also, this study showed that in the four underground subway stations, the annual average concentrations of PM10 and PM2.5 were 1.5-1.7 times higher than those in the outdoor ambient, respectively.

Aim of study: The objective of this study was to optimize the germination of A. spinosa seeds after different physical pretreatments by thermal shock to establish a simple, effective, and less expensive procedure.

Area of study: The study was conducted in the laboratory on seeds from four regions of Morocco (Aoulouz, Essaouira, Sidi Bou Othmane, and Boulaouane).

Material and methods: The seeds were dried and stored. Before the launching of the experimental protocol, they were dehulled and applied each their pre-treatment for the four provenances. The pre-treatment used are the following. C: control without thermal shock, HC1: freezing, HC2: hot water, HC3: freezing + hot water.

Main results: The results showed that the onset of germination of argan seeds subjected to pretreatment HC3 was reduced by 2 days on mean compared to seeds that were subjected to pretreatment (C). The application of the cold or hot pretreatment allowed us to reach up to 82% of the final percentage of germination. However, the combination of two pretreatments allowed us to reach up to 100% of the final germination percentage.

Highlights: Freezing combined with hot water significantly improved the germination of A. spinosa seeds. This pretreatment could be recommended in the nursery for practitioners

Significant Oil Palm Diseases Impeding Global Industry: A Review
Authors: Saipol Anuar Mohd Amar Shafiq , Syd Ali Nusaibah
Published: March 2022

Oil palm is the most well-known high yielding and versatile oil crop grown. In 2019, Malaysia ranked as the world's second largest producer of palm oil products (28%) after Indonesia (57%), contributing around USD 9.07 billion to the country’s Gross Domestic Product (GDP) and has been the main economic contributor in the agriculture sector. In recent years, increase in demand has paralleled production. However, pests and diseases have been the major constraints in production causing reduction in palm oil quality and yield. This paper reviews a current status of oil palm diseases of significant economic importance affecting the global oil palm industry. Plant diseases such as basal stem rot (BSR), Fusarium wilt, Phytophthora bud rot, Pestalotiopsis leaf spot, common spear rot, orange spotting and upper stem rot (USR) have been classified as the major diseases of oil palm in terms of economic importance. This paper discusses on the damages caused by the diseases, the causal pathogens and pathogenicity, symptoms as well as treatments or control in the view of developing measures to manage occurrences.
How a Sustainable Renovation Influenced the Environmental Values of Those Involved
Authors: Bahho Mazin , Vale Brenda
Published: March 2022

Renovation projects are complex and multi-layered as they often deal with architectural, cultural, and social values, as well as aspects of energy efficiency and finance. This article discusses the impact that engaging in a sustainable retrofit had on the environmental values of those involved. The project was the renovation of an existing log cabin structure located on the Ōtātara heritage site at the Eastern Institute of Technology campus, New Zealand. The aim was to make the existing structure as near-zero energy as possible, so it would act as a demonstration facility for sustainable building and living practices and inspire the local community to adopt pro-environmental practices. The completed project is being used by the Eastern Institute of Technology as home to a nature-based education facility where the cultural and creative connections to land, sustainable use of resources, restoration of ecology, and biodiversity management are communicated. The article explains why people chose to be involved with the various stages of renovating and using a sustainable building and their attitudes towards behaving sustainably. The research approach is explorative, making use of qualitative data analysis methods. The study argues that getting involved in a sustainable building can potentially change the values of people through active, systemic, and successive learning, both in the building and operation phases. The key finding shows that involvement only increased as the project gained momentum as people could see that taking part would produce something tangible.

Published: March 2022

The Trump presidency featured a high volume of contentious mobilization. We describe the collection and aggregation of protest mobilization data from 2017 to 2021 and offer five observations. First, the protests were sustained at a high level throughout the Trump presidency, with the largest subset of protests positioned against Trump and the administration’s policies. Second, the grievances that drove the protests varied. Third, the National Student Walkout and the antiracism protests in 2020 had the broadest geographic spread of any reported protests in U.S. history. Fourth, the vast majority of protests did not have arrests or injuries; they were nonviolent protests. When there were arrests, most people who were arrested were committing nonviolent civil disobedience, not aggression or interpersonal violence. Fifth, in 2020, a sustained period of right-wing countermobilization began around the issues of COVID-19 lock-downs, policing and race, and Trump’s false claim about the presidential election.
“WE’RE ALL IN THIS TOGETHER”: LEVERAGING A PERSONAL ACTION FRAME IN TWO MEN’S RIGHTS FORUMS
Authors: Carian Emily K.
Published: March 2022

The men’s rights movement has used forums, blogs, and social media to invest individuals in a deeply misogynist agenda, organizing around the belief that feminism has systematically privileged women and disadvantaged men. In this article, I analyze data from two online men’s rights forums to examine how men’s rights activists construct this belief and identify what appeals to them about it. Posters co-construct a highly personalizable and appealing personal action frame through which they share personal experiences that they consider proof of women’s privilege, men’s disadvantage, and feminist wrongs. In contrast to previous work on personal action frames, I find that this template for account sharing is a powerful tool for building solidarity and constructing collective identity. Men’s rights activists’ use of a personal action frame allows them to build a fictional yet credible narrative of men’s oppression, with important repercussions for gender inequality and movement dynamics.

ResumoEste estudo de natureza qualitativa do tipo exploratória e descritiva, no qual apresentamos uma descrição sobre duas atividades que compõem uma sequência didática investigativa para a aprendizagem conceitual do Efeito Fotoelétrico (EFO) de alunos do Ensino Médio de um colégio estadual do município de Londrina, no Estado do Paraná. As atividades em análise seguem os conceitos de Sequências de Ensino Investigativas (SEI’s) propostas por Carvalho (2013), em que as sequências de ensino buscam modificar a atuação do professor e do aluno em todo o processo didático. A primeira atividade é uma modelagem para o EFO, na qual estabelecemos uma analogia entre o fenômeno mecânico e o quântico, por meio de um plano inclinado que permite a analogia entre a Conservação da Energia Mecânica em Colisões Elásticas e o EFO, e a segunda atividade trata-se de uma abordagem investigativa do fenômeno mediado pela eletrização no eletroscópio. Como resultados acerca das possíveis contribuições das atividades para a aprendizagem conceitual do Efeito Fotoelétricos, ambas possibilitam a argumentação e o levantamento de hipóteses e apresentam um potencial didático para serem aplicadas em sala de aula. O uso de atividades experimentais pode fornecer aos alunos uma leitura mais acessível da realidade e de fenômenos naturais.

AbstractThis study a description of two activities that compound an investigative didactic sequence for the conceptual learning of the Photoelectric Effect (EFO) of High School students from a state school of Londrina, in the State of Paraná. The activities under analysis follow the concepts of Investigative Teaching Sequences (Sequências de Ensino Investigativas) (SEI’s) proposed by Carvalho (2013), in which the teaching sequences seek to modify the teacher and the student performance throughout the didactic process. The first activity is a molding for the EFO, in which we establish an analogy between the mechanical and the quantum phenomenon, through an sloped plane that allows the analogy between the Conservation of the Mechanical Energy in Elastic Collisions and the EFO, and the second activity deals with an investigative approach to the phenomenon mediated by electrization in the electroscope. As results about the possible contributions of the activities to the conceptual learning of the Photoelectric Effect, both enable the argumentation and the hypothesis raising and present a didactic potential to be applied in the classroom. The use of experimental activities can provide students a more accessible reading of reality and of natural phenomena.

ResumoA pandemia Covid-19 obrigou as escolas a pararem seus atendimentos presenciais e a buscarem uma alternativa para acessarem os alunos e darem segmento as propostas educacionais. E diante de realidades diferenciadas no Brasil, cada professor teve um desafio em cada região, em que se localiza uma escola. Esta pesquisa tem por objetivo investigar a forma como as professoras do ciclo de alfabetização incorporaram os conhecimentos e os recursos tecnológicos em suas práticas no ensino remoto durante a pandemia da Covid-19. Este artigo é o resultado de uma pesquisa exploratória de abordagem qualitativa por meio do grupo focal com quatro professoras do ciclo de alfabetização de uma escola pública da região do grande ABC/SP. Traz reflexões sobre a adaptação e dificuldades dos professores na transição do ensino presencial para o ensino remoto, o uso da tecnologia por parte dos professores, alunos e famílias e a oferta do ensino para manter o vínculo entre a escola e a família. Conclui-se que os professores e o ensino necessitaram de adaptações e ressignificações para alcançar os objetivos propostos, que tanto os alunos como suas famílias também passaram por processos de adequações com um ensino feito em casa, que somente os recursos tecnológicos não garantem o vínculo com a escola e o efetivo ensino, precisando considerar os aspectos do acesso das famílias aos instrumentos e meios que possibilitam o uso da tecnologia no ensino remoto.

AbstractThe Covid-19 pandemic forced schools to stop their face-to-face services and to look for an alternative to access students and provide segment for educational proposals. And given the different realities in Brazil, each teacher had a challenge in each region where a school is located. This research aims to investigate how teachers in the literacy cycle incorporated knowledge and technological resources into their practices in remote education during the covid-19 pandemic. This article is the result of an exploratory research with a qualitative approach through a focus group with 4 teachers from the literacy cycle of a public school in Grande ABC/SP region. It brings reflections on the teachers’ adaptation and difficulties in the transition from classroom teaching to remote teaching, the use of technology by the teachers, students and families, and the offer of teaching to maintain the bondbetween school and family. It was concluded that teachers and teaching needed adaptations and resignifications to achieve the proposed objectives, that both students and their families also went through adaptation processes with home-based teaching, that only technological resources do not guarantee the bond with the school and effective teaching, needing to consider aspects of families' access to instruments and means that enable the use of technology in remote education.

Avrupa Yeşil Mutabakatı ve Yeşil Ekonomiye Geçiş: Enerji Senaryoları Üzerinden Bir Değerlendirme
Authors: KÜÇÜK Gülay , YÜCE DURAL Betül
Published: March 2022

Bu çalışmada, yeşil ekonomi anlayışının Avrupa Birliği tarafından nasıl uygulandığı ve bu uygulamaların AB’nin 2050’de iklim hedeflerine ulaşmada ne derece etki edebileceği incelemektedir. Çalışma, bu soruya geçerli bir yanıt bulmak amacıyla, Avrupa Birliği Komisyonu’nun 2019 yılında duyurduğu Avrupa Yeşil Mutabakatı ve bu doğrultuda 2050 yılına kadar dünyanın ilk iklim nötr kıtası olma hedefi üzerinden oluşturduğu Avrupa Birliği’nin enerji kurumları ve uluslararası enerji kuruluşlarının gelecekteki enerji senaryolarına odaklanmaktadır. Araştırma sürecinde 15 farklı enerji raporunun gelecek enerji senaryoları incelenmiştir. Gelecek enerji senaryoları Avrupa Birliği, Uluslararası Enerji Ajansı ve Uluslararası Yenilenebilir Enerji Ajansı gibi uluslararası kuruluşların yayınladıkları raporlardan elde edilmiştir. Araştırma süreci sonucunda elde edilen bilgiler yorumlanarak bulgular oluşturulmuştur. Araştırmanın sonucuna göre; Avrupa Birliği, Avrupa Yeşil Mutabakatı doğrultusunda planladığı eylem alanlarıyla birlikte Paris İklim Anlaşması ile uyumlu politikaları uygulamaya devam ettiği takdirde 2050 hedeflerine yaklaşması mümkün olabilecektir. Ancak mevcut politika uygulamaları ve hedefler ile hiçbir senaryo Avrupa Birliği’nin iklim nötr kıta olması için %100 yeterli olmamaktadır.

Examining the Challenges Making Excellence Inclusive
Authors: Clayton-Pederson Alma
Published: March 2022

The term Inclusive Excellence (IE) is being applied to many efforts in higher education to address past exclusionary practices. IE is more than a term, it is a vision of what could be. It is a deliberate set of actions to ensure that all students, especially those who have historically been underserved by the fragmented attempts in higher education to address the disparities in student learning outcomes. Readers are expected to learn about strategies to genuinely make excellence inclusive to address existing inequities in education.
Covid-19 Döneminde E-Şikâyet Yönetimi Perspektifinden Müşterilerin Çevrimiçi Alışverişte Karşılaştıkları Sorunlar
Authors: KOCABAŞ İsmail
Published: March 2022

Müşteriler, Covid-19 gibi küresel bir kriz karşısında psiko-sosyal ve ekonomik açıdan farklı zorluklarla mücadele etmek zorunda kalmıştır. Müşterilerin çevrimiçi alışveriş deneyiminden memnun olma isteği, markaların ise, yaşam kaynağı olan sadık müşterilere sahip olma arzusu, karşılaşılan sorunların ve şikâyetlerin çözüme kavuşturularak memnuniyetin sağlandığı etkili bir e-şikâyet yönetimini gerekli kılmaktadır. Bu nedenle iletişim sürecinde gürültünün bir parçası olan müşteri sorunlarının dikkate alınması gerekmektedir. Bu kapsamda, araştırma, “giyim/ayakkabı ve aksesuar” kategorisinin yüksek oranda tüketimi olması nedeniyle Covid-19 döneminde gerçekleştirilen çevrimiçi alışverişlerde, müşterilerin karşılaştıkları sorunları ortaya koyarak etkili bir e-şikâyet yönetimi için yol gösterici olmayı amaçlamaktadır. Araştırmada, alanında lider pozisyonda faaliyet gösteren marka ile onun en yakın rakibi olan marka, amaçlı örneklem esas alınarak belirlenmiş olup, Türkiye’nin e-şikâyet yönetimi gerçekleştirmedeki en önemli sosyal platformlarından birisi olması nedeniyle veriler “şikayetvar.com” sitesi üzerinden, 5 Nisan-5 Mayıs 2021 tarihleri arasındaki 30 günlük bir dönem dâhilinde elde edilen 690 şikâyet, nitel ve betimsel içerik analizi tekniğiyle analize tabi tutulmuştur. Araştırmanın öne çıkan sonuçlarına bakıldığında, en çok şikâyeti lider markanın aldığı görülmekle birlikte en çok şikâyeti çözüme ulaştıran, en çok müşteri memnuniyeti belirtir teşekkür mesajı alan ve en fazla şikâyeti yayından kaldırılan da yine kendisidir. Bu durum, lider markanın çevrimiçi mecralarda etkili bir iletişim gerçekleştirdiğinin de göstergesidir. Ayrıca, markaların doğru iletişim yaklaşımı ve etkili bir e-şikâyet yönetimiyle kendilerine yöneltilen şikâyetleri çözüme ulaştırması neticesinde %82,0 ile %90,1 oranında müşteri memnuniyeti sağlama başarısına ulaşabilecekleri sonucunu ortaya koymaktadır.
Generative Adversarial Networks for Non-Raytraced Global Illumination on Older GPU Hardware
Authors: Harris-Dewey Jared , Klein Richard
Published: March 2022

We give an overview of the different rendering methods and we demonstrate that the use of a Generative Adversarial Networks (GAN) for Global Illumination (GI) gives a superior quality rendered image to that of a rasterisations image. We utilise the Pix2Pix architecture and specify the hyper-parameters and methodology used to mimic ray-traced images from a set of input features. We also demonstrate that the GANs quality is comparable to the quality of the ray-traced images, but is able to produce the image, at a fraction of the time.

Authors: Sharma Rohini , Abrol Sameer
Published: March 2022

The outbreak of a mysterious pneumonia, reported from a sea food wet market of Wuhan, Hubei, China in 2019 has now taken the shape of a pandemic with successive waves sweeping across nations and creating havoc. Moreover, the transmission speed is much more than earlier severe acute respiratory syndrome coronavirus (SARS) and Middle East respiratory syndrome coronavirus (MERS) making it imperative for the use of protective gears like masks, gloves and personal protective equipment(PPE) kits but ironically they in itself lead to a range of cutaneous complications making it difficult to continuously wear them.

: The purpose of this study was to assess the various adverse dermatological manifestation among general population in view of the various precautions taken against COVID-19.

This was a descriptive questionnaire based study and a total of ­105 patients were taken up for the study who came to the dermatology outpatient department(opd) with dermatological manifestations following covid 19 protection measures who met the inclusion criterias . All those who didn’t give consent for the study were excluded from the study.

: A total of 105 questionnaires were collected. The males outnumbered the females with 71 males and 34 females. The most common reason implicated was wearing masks, goggles in 42(36.19%) patients followed by use of hand sanitizers and frequent hand washing seen in 36(12.4%) patients. In 20(19%) patients, use of gloves resulted in adverse dermatological manifestations followed by the use of PPE kits in 7(6.6%).

: The prevalence of Covid -19 precaution taking measures is of utmost importance specially among the health care workers and office going people who have to adorn it for prolonged hours thus leading to adverse effects. Prompt diagnosis and this data can offer valuable insights to help modify the adverse effects.

Published: March 2022

Pink lips have always been considered an attribute of a beautiful face. The content of lip cosmetics is cause for concern as they are easily ingested. Hence, the need for lip-lightening by other means, like lasers. We aimed to find the efficacy and optimum fluence of the Qs-Nd :YAG 1064 nm laser in reducing lip melanosis of unknown cause.

A prospective Case series study was carried out. Fifteen consecutive patients with lip melanosis of unknown etiology, were selected. Patients were advised to undergo Lip toning with Spectra laser (Qs Nd:YAG 1064 nm) every 2 weeks, for atleast 8-10 sessions. Before each session, photographs and Digital dermoscopy (polarized,20x) pictures were taken to assess outcome. Lip pigmentation and erythema were assessed quantitatively using skin colorimetric device called ‘Dermacatch’

Ten patients completed atleast 5 sessions. Of this, four patients completed 7-8 sessions and showed significant clinical improvement. Dermoscopic changes in patients after treatment are ‘hazy whitening’ of areas which were ‘velvety’ in color. The four patients who showed clinical improvement also showed dermoscopic changes.

Lip pigmentation improvement is slow and fluence-dependent and may need more than five sessions. The effective fluence for lip lesions is 3 to 4 times that for facial melanosis. Patients maybe started on higher fluences depending on tolerance. Dermoscopic changes precede clinical improvement.

Lip pigmentation was found to respond to high fluences only. Dermoscopic changes can give an early indication of possible clinical improvement that can be expected. Skin colorimetry device did not correlate well with clinical features with respect to melanosis of lip.

Physical, Thermal and Mechanical Characterization of a New Material Composite Based on Fibrous Wood Particles of Date Palm Tree
Authors: Djoudi Tarek , Djemai Hocine , Hecini Mabrouk , Ferhat Ahmida
Published: March 2022

The objective of this work is to valorize the waste from date palms tree which is often abandoned in the palm groves The aim is to produce a new composite based on this waste that can be used as an alternative material to the conventional insulators. The approach consists in making a composite material from petiole wood (WPC) in different particle sizes (0 to 1, 1 to 3 and 3 to 5) mm. We then characterized the physical, thermal and mechanical properties of this new material (WPC). The results obtained proved the relative anisotropy of the material and the effect of the particle size distribution on these properties. The composites (WPC) had low density in the range (0.16-0.56) g/cm3 and also exhibited low thermal conductivity, in the range (0.109-0.122)W/mK°. These weak properties make it possible to use (WPC) as an effective insulator. These characteristics were quite acceptable in comparison with other thermal insulation materials such as cork agglomerate and traditional wood. The interesting mechanical properties of the new composite (WPC) have been shown by the tensile tests and the three-point flexural tests. These results make it possible to valorize these materials (WPC) for possible industrial applications.
