La catégorisation, entre cognition et interaction
Authors: Zogmal Marianne , Filliettaz Laurent
Published: October 2020

L’ambition de cette conclusion est de revenir sur quelques-uns des présupposés théoriques que véhiculent les textes présentés dans le cadre de ce volume, et de les faire dialoguer avec un point de vue alternatif, celui de l’analyse de l’interaction. En dépit des éléments de variation, voire de controverses qui les caractérisent, les articles convergent, à certains égards, sur la manière de conceptualiser la problématique de la catégorisation comme un phénomène de nature cognitive. Ils prennent également position, de manière plus ou moins explicite, sur la manière dont ces phénomènes cognitifs s’articulent à la problématique de l’action, de la temporalité et du langage, notamment. Après avoir dégagé ces éléments transversaux de positionnement qui permettent de « catégoriser » les textes produits, nous proposons de considérer la problématique des catégories dans les conditions de leur mise en œuvre dans les interactions verbales et non verbales. Un déplacement du regard est ici proposé, qui amène à renverser, ou du moins à mettre en perspective les présupposés d’une approche cognitive de la catégorisation. Afin d’illustrer notre propos, nous terminons cet article en présentant quelques données empiriques portant sur la conduite d’une activité ludique dans le champ de l’éducation de la petite enfance. Nous y montrons que des processus de catégorisation y sont à l’œuvre en permanence, et qu’ils constituent une condition de la conduite de l’activité, dès lors que celle-ci est conçue comme un processus dynamique et situé de coordination entre les participants.
Que recouvre la fonction d’enseignant référent ? Cartographie d’une activité
Authors: Laville Matthieu
Published: October 2020

Depuis la rentrée scolaire 2006, les enseignants référents ont la charge d’accompagner les parcours de scolarisation des élèves handicapés, en coordonnant les actions entre les différents partenaires par le biais d’Équipes de suivi de scolarisation (ESS). S’appuyant sur la sociologie des groupes professionnels, cet article vise à étudier l’activité concrète qui se cache derrière l’appellation générique d’enseignant référent. Il propose d’apprécier cette activité à l’aune des prescriptions encadrant cette fonction. L’article expose alors les étapes qui ont balisé le passage graduel d’une ethnographie exploratoire à la construction d’un questionnaire à portée nationale. Les résultats mettent en évidence des traductions parfois différentes des prescriptions et aboutissent à une cartographie des principaux pans de l’activité. Ils permettent enfin de saisir les déterminants qui influencent le plus la fréquence des programmations d’ESS.
Comment analyser ce que font les enseignants dans la préparation de leurs cours ? Ébauche d’un cadre conceptuel
Authors: Maitre Jean-Philippe , Huchette Michaël , Bruillard Éric
Published: October 2020

En préparant leurs cours, les enseignants fabriquent des supports pour leurs élèves, et mobilisent pour cela des ressources qui leur sont propres et d’autres qu’ils trouvent sur internet, auprès de collègues, etc. Cette activité ordinaire s’avère complexe et faiblement documentée par la recherche. De quoi les enseignants partent-ils pour préparer leurs cours ? Comment s’y prennent-ils pour en faire des supports d’enseignement ? Comment les supports de cours sont-ils recyclés d’une année sur l’autre ? Cet article propose quelques repères théoriques pour l’analyse de ces questions. Le propos s’inscrit dans le cadre du projet ANR ReVEA, présenté succinctement. Il est étayé par la littérature de recherche – rare sur le sujet – et par des données d’enquête par entretien auprès d’enseignants français de technologie au collège et de sciences et technologies de l’ingénieur au lycée. La conclusion pose la question du caractère systémique de l’organisation de cette part du travail enseignant, ouvrant de nouvelles perspectives de recherche.

Authors: Nazeer Ishrat , Rashid Mamoon , Gupta Sachin Kumar , Kumar Abhishek
Published: October 2020

Twitter is a platform where people express their opinions and come with regular updates. At present, it has become a source for many organizations where data will be extracted and then later analyzed for sentiments. Many machine learning algorithms are available for twitter sentiment analysis which are used for automatically predicting the sentiment of tweets. However, there are challenges that hinder machine learning classifiers to achieve better results in terms of classification. In this chapter, the authors are proposing a novel feature generation technique to provide desired features for training model. Next, the novel ensemble classification system is proposed for identifying sentiment in tweets through weighted majority rule ensemble classifier, which utilizes several commonly used statistical models like naive Bayes, random forest, logistic regression, which are weighted according to their performance on historical data, where weights are chosen separately for each model.

Authors: Chauhan Prachi , Mandoria Hardwari Lal , Negi Alok , Rajput R. S.
Published: October 2020

In the agricultural sector, plant leaf diseases and harmful insects represent a major challenge. Faster and more reliable prediction of leaf diseases in crops may help develop an early treatment technique while reducing economic losses considerably. Current technological advances in deep learning have made it possible for researchers to improve the performance and accuracy of object detection and recognition systems significantly. In this chapter, using images of plant leaves, the authors introduced a deep-learning method with different datasets for detecting leaf diseases in different plants and concerned with a novel approach to plant disease recognition model, based on the classification of the leaf image, by the use of deep convolutional networks. Ultimately, the approach of developing deep learning methods on increasingly large and accessible to the public image datasets provides a viable path towards massive global diagnosis of smartphone-assisted crop disease.
Investigation on the Wear Behavior of Coatings for Lubricant-Free Deep Drawing Processes with a Novel Application-Oriented Test Rig
Authors: Henneberg Johannes , Merklein Marion
Published: October 2020

Lubricant-free deep drawing is motivated by the avoidance of using environmentally harmful lubricants as well as the potential for shortening the process chain by eliminating lubricant application and component cleaning. Central challenges of dry deep drawing are a significant increase in friction as well as in adhesive tool wear due to a lack of a separating lubricant layer between tool and workpiece. An approach to meet these challenges is the modification of the tools through diamond-like coatings. Based on findings from laboratory tests, a-C:H and ta-C coatings were selected and their effectiveness in overcoming these challenges was demonstrated in single stroke tests in previous research. In order to use the process-specific advantages of forming technology, high tool life is required. In this context, this research aims at investigating the application behavior of a-C:H and ta-C coatings during lubricant-free deep drawing of a high number of components made of the aluminum alloy AA5182. For this purpose, a new wear test rig is applied, which enables the time and material efficient production of high quantities. Numerical methods are utilized to identify the drawing die radius as well as the blank holder as the highest loaded areas. Based on these findings, the wear of the coatings as well as that of an uncoated tool as a reference is analyzed in these areas by optical and tactile measurements. In addition, the influence of tool wear on the component surface quality is determined. It is proven that the ta-C coating increases the tool life from 10 components in uncoated condition up to 3,000 components.
Test Method for Friction Characterization of Rivets
Authors: Wituschek Simon , Kuball Clara Maria , Merklein Marion , Lechner Michael
Published: October 2020

Due to continuously increasing requirements on lightweight sheet metal constructions, new processes and technologies are necessary to face current and future challenges. A trend in lightweight construction is the multi-material mix with sheets of different geometric and mechanical properties. To manufacture these so-called composite structures, new joining technologies and methods are required. One possibility is the further development of the self-pierce riveting joining process. For the simulation and evaluation of new and adapted processes of self-pierce riveting, numerical models are used to investigate process parameters and constraints. Besides precise material models for the numerical simulation of this joining process, the identification of friction parameters between the individual sheets and rivet elements is necessary to achieve exact results. Thus, a method is necessary to identify the friction coefficients between rivet elements and sheets. Such a method is presented and evaluated in this work. Different process parameters like the relative speed are varied for the experimental investigations and an analysis of the respective influence on the resulting friction coefficients is conducted. For the use of the test set-up, coefficients of friction are determined for rivet elements “RIVSET® C 5.3x5.5” (Böllhoff GmbH) coated with Almac® in combination with two different sheet materials HCT590X+Z and EN‑AW 6014.
Wear Behaviour of Coated Cemented Carbide Inserts in an Oxygen-Free Atmosphere when Machining Ti-6Al-4V
Authors: Denkena Berend , Dittrich Marc André , Krödel Alexander , Worpenberg Sebastian , Matthies Jonas , Schaper Florian
Published: October 2020

The machining of difficult-to-cut materials such as titanium plays a key role in several industries such as aerospace or medical. Approaches to overcome many difficulties when machining these materials can be an appropriate coating system for cemented carbide cutting tools. However, the atmosphere under which machining takes place, influencing the chemical tool wear, has not been taken into consideration. This work examines the tribochemical wear resistance of TiN, TiAlN and CrAlN coated carbide tools under different atmospheric conditions when cutting Ti6Al-4V. Air, technically pure argon and silane-doped argon is used to determine the influence of different oxygen levels on the wear behaviour of the tools. It has been found that oxidation of tools and tool coatings plays a significant role in tool wear when dry cutting titanium. Best results were generated using CrAlN and uncoated inserts where an increase in tool life up 50 % can be achieved when cutting in oxygen levels corresponding to extreme high vacuum (XHV) adequate atmospheres by using silane-doped argon. The benefits of XHV adequate atmospheres also have an effect on TiAlN-and TiN based coatings, but the chemical interaction of Ti element in the coating with the workpiece material, which presumably reduces wear resistance of cutting tools, cannot be outweighted or equalised by applying oxygen free atmospheres.
Influence of Tool Wear on the Load-Bearing Capacity of Shear-Clinched Joints
Authors: Wiesenmayer Sebastian , Merklein Marion
Published: October 2020

Shear-clinching allows the joining by forming of dissimilar materials with high differences between their mechanical properties without additional fasteners. Since the lower joining partner is indirectly shear cut during the process, even ultra-high strength materials can be joined. However, the cutting of the high-strength materials as well as the extrusion of the upper joining partner leads to high process forces and therefore to high tool loads. This applies in particular for the die, which is highly stressed during the cutting phase and therefore plastically deformed. Within the scope of this work, the influence of the occurring wear on the formation of the joint and its load-bearing capacity is analyzed for a scope of 500 strokes. For this purpose, press hardened 22MnB5 is used as lower joining partner. Its high strength leads to the plastic deformation of the cutting edge, which increases within the first 200 strokes. Afterwards only minor changes occur. Yet, no effect of the occurring wear on the joint formation and the joint strength, which was tested under shear and tensile load, could be determined. Functioning joints could still be produced for more than 500 strokes as the load-bearing capacity remained on a comparable level.
Wear Resistance of Hard Particle Reinforced Copper Alloys Generated by Laser Melt Injection
Authors: Warneke Philipp , Seefeld Thomas
Published: October 2020

Highly conductive copper alloys are used for several tools in casting and welding technology. In order to improve the poor wear resistance of these alloys, metal matrix composite (MMC) layers were generated by laser melt injection (LMI). During LMI, a weld pool is induced on a substrate by a laser beam and a wear-resistant filler material is injected into this weld pool by a powder nozzle. In contrast to laser cladding, the filler material remains in the solid state and the substrate works as matrix material. Thereby, specific material properties of the substrate - e.g. a high thermal conductivity - can be provided not only in the core of the part but also within the coating. Fused tungsten carbide (FTC) was used as reinforcing material. It was shown that homogeneous MMC layers out of the copper alloy Hovadur® CNCS and FTC can be produced by laser melt injection. High process velocities of 8.75 m/min could be reached. For assessing the wear resistance, oscillating wear tests with counterparts made of steel were carried out and the wear height and the wear volume were determined. The particle reinforcement lead to a significant increase in wear resistance. Only one wear mechanism - abrasion - was identified.
Designing Amorphous Carbon Coatings Using Numerical and Experimental Methods within a Multi-Scale Approach
Authors: Tremmel Stephan , Marian Max , Rothammer Benedict , Weikert Tim , Wartzack Sandro
Published: October 2020

Amorphous carbon coatings have the potential to effectively reduce friction and wear in tribotechnical systems. The appropriate application of amorphous carbon layers requires both, a very good understanding of the tribological system and knowledge of the relationships between the fabrication of the coatings and their properties. In technical practice, however, the coatings’ development and their selection on the one hand and the design of the tribological system and its environment on the other hand are usually very strongly separated. The present work therefore aims to motivate the integrated development of tribotechnical systems with early consideration of the potential of amorphous carbon coatings. An efficient integrated development process is presented, which makes it possible to determine the boundary conditions and the load collective of the tribological system based upon an overall system and to derive the requirements for a tailored coating. In line with the nature of tribology, this approach must cover several scales. In this respect, the development process follows a V-model. The left branch of the V-model is mainly based upon a simulation chain including multibody and contact simulations. The right branch defines an experimental test chain comprising coating characterization to refine the contact simulation iteratively and tribological testing on different levels to validate the function fulfillment. Within this contribution, the outlined approach is illustrated by two use cases, namely the cam/tappet-pairing and the total knee replacement.

On Erdős–de Bruijn–Kingman’s problem on regularity of reciprocals for exponential series
Authors: Gomilko Alexander , Tomilov Yuri
Published: October 2020

Motivated by applications to renewal theory, Erdős, de Bruijn and Kingman posed a problem on boundedness of reciprocals

(1 − z)/(1 − F(z))

in the unit disc for probability generating functions

F(z)

. This problem was solved by Ibragimov in 1975 by constructing a counterexample. In this paper, we provide much stronger counterexamples showing that the problem does not allow for a positive answer even under rather restrictive additional assumptions. Moreover, we pursue a systematic study of

L^p

-integrabilty properties for the reciprocals. In particular, we show that while the boundedness of

(1 − z)/(1 − F(z))

fails in general, the reciprocals do possess certain

L^p

-integrability properties under mild conditions on

F

. We also study the same circle of problems in the continuous-time setting.
Employment hysteresis: an argument for avoiding front-loaded fiscal consolidations in the eurozone
Authors: Mota Paulo R. , Fernandes Abel L.C. , Vasconcelos Paulo B.
Published: October 2020

The austerity policies applied by the eurozone peripheral governments under the Troika financial assistance programmes have contributed to a sharp reduction in aggregate demand, regardless of the unconventional measures undertaken by the European Central Bank (ECB). The ECB decreased the interest rate on the main refinancing operations to zero and has been buying assets from banks on a massive scale under the Expanded Asset Purchase Programme. The fact that these extraordinary measures have not been enough to promote a strong recovery shifts the focus back onto fiscal policy. The value of impact fiscal multipliers and the size of hysteretic effects are key factors for assessing the effects of fiscal policy. There is widespread evidence that public expenditure multipliers are greater than one, especially when the economy is depressed. However, less is known about the importance of hysteresis effects. Using the linear play hysteresis operator, we find that hysteresis effects are important in the eurozone peripheral countries. Large fiscal impact multipliers combined with the presence of hysteresis implies that front-loaded austerity depresses the economy in the short run, and these effects may persist in the long run.
Ouverture de ‘Circular Economy & New Business Models’
Authors: Salvioni Daniela , Brondoni Silvio
Published: October 2020

Circular economy business models essentially fall into two main groups: (1) models focused on reorienting traditional business, and (2) models that involve creating a new business specifically aimed at recovering resources. The timing and ways of transforming an old business into a circular one could find useful drivers in a systemic approach that involves policy makers and legislators to implement effective regulations and incentives, the financial sector, public authorities and civil society. By converse, big global corporations often develop circular economy within a company’s network. From this perspective, some companies are specifically oriented towards recycling, while other companies belonging to the same group use raw materials obtained from recycling, thus gaining an extensive competitive advantage for all the network’s companies (competitive circular economy).
The Circular Enterprise
Authors: Zucchella Antonella , Urban Sabine
Published: October 2020

The circular economy challenges business firms to adopt principles of sustainability by closing, narrowing, extending the loop of resources, in order to minimize impact on the planet. Firm embracing circularity principles have to innovate not only products and processes, but primarily models of business. Also they need to include suppliers and customers in their model, as well as any relevant stakeholder, developing eco-systemic business models. The challenge of implementing circular business models encompasses both established and larger organizations and younger ventures (born circular firms).

Objetivou-se descrever o caso de um cão com luxação traumática de cotovelo que obteve bons resultados após correção ortopédica com parafusos e poliéster trançado. O tutor referiu que animal evadiu-se de sua residência e retornou após 3 dias sem apoiar o membro torácico esquerdo. O paciente foi encaminhado a clínica veterinária Uningá após 12 dias de seu retorno. Na avaliação clínica pôde-se observar: claudicação sem apoio do membro torácico esquerdo, dor, crepitação e instabilidade da articulação do cotovelo com deslocamento lateral da cabeça do rádio e do olécrano em relação ao úmero distal. Confirmou-se o diagnóstico de luxação lateral do cotovelo pelo exame radiográfico. O paciente foi submetido à cirurgia ortopédica e após 15 dias do procedimento cirúrgico, observou-se boa cicatrização da ferida com discreta claudicação do membro operado. Após 90 dias de pós-operatório o paciente apresentava boa deambulação, sem indícios clínicos de claudicação, dor, instabilidade e crepitação do membro operado. Concluiu-se então com este relato que o uso dos parafusos associados ao fio de poliéster trançado em figura de “8” foram uma boa opção no tratamento da luxação traumática de cotovelo.

Para ele, estes personagens eram o malandro, o otário, o caxias e o renunciador. Este artigo tratará somente dos três primeiros e incluirá mais um personagem, o “bandido”, que talvez complete um sistema mais adequado para o entendimento dos tempos em que vivemos.
Para além das tentativas de desmonte da EBC
Authors: Gobbi Maria Cristina , Monteiro de Godoy Jéssica , Souza Navarro Thiago de
Published: October 2020

A instabilidade, conferida previamente pela Lei 11.652/08, que consolidou a criação da EBC e possibilitava ingerências na empresa pública, bem como por um contexto de anacronismo regulatório do setor, já definia como incerto o caminho da comunicação pública brasileira. Com o início do governo de Michel Temer (PMDB) no Brasil, após abertura de um processo polêmico de impeachment na Câmara Federal, em abril de 2016, e sua consolidação no Senado, em agosto, a EBC, especialmente na figura da TV Brasil, viu-se ainda mais ameaçada. O processo de desmonte ganhou fôlego com a Medida Provisória 744/16, assinada em setembro e consolidada pela Lei 13.417/17, em vigência desde março. Considerando esse cenário, assim como a premissa da comunicação pública como princípio constitucional e sua implantação correspondente às melhores práticas estrangeiras, a discussão da temática é mais que necessária, é urgente.
THE EGGPLANT BLIGHT AND FRUIT ROT IN PORTO RICO
Authors: Nolla J. A. B.
Published: October 2020

1. A serious disease of eggplants known in Porto Rico as "lunares de la hoja y tallo" and "podredumhre de la fruta", in the United States of North America as leaf blight, foot-rot, leaf-spot, stem-blight. fruit-rot, eggplant-blight and seedling-stem-blight and in Cuba as "mancha de la hoja" and "enfermedad del tallo" exists in Porto Rico. 2. All varieties of eggplant are more or less equally susceptible under Porto Rican conditions. Color of plant or of fruit has no bearing on susceptibility or resistance. 3. The disease usually brings a loss of 50 per cent or over of the crop. 4. The symptoms of the disease appear on all above-ground parts of the plant. A seedling blight, stem and petiole cankers, spots on leaf blades, fruit stalks and calices and a rotting of the young and mature fruit are produced. 5. The fungus may occur inside the seed. 6. The pathogene responsible for the malady is Phomopsis vexans (Sacc. & Sydow) Harter. 7. Variations of the fungus as have been observed elsewhere do not appear to occur in the fungus in Porto Rico. 8. The size of the pyenidiospores ranges from 5 to 8 microns in length to 1.3 to 3 microns in width. 9. The germ tube of a germinating spore may either enter through a stoma, enter through a wound or force its penetration through the cuticle. 10. Secondary cycles repeatedly occur in fields. 11. The fungus is capable of a saprophytic existence. 12. The prevailing temperature in Porto Rico seems adequate for spore germination. 13. Moisture is a very important factor in outbreaks of the disease. 14. The disease is probably controlled by a three- or four-years rotation. 15. Plants with the symptoms of the disease should be promptly removed from fields. 16. Although seed treatment is beneficial it never completely eliminates the pathogene. 17. Clean seed from unaffected fruit should be demanded. 18. Infested soils should be avoided in preparing seedbeds. 19. Inoculated soils can he rendered safe for seedlings if drenched with a 1-50 formaldehyde solution at the rate of one-half gallon per square foot of soil surface. An application of 4-4-50 Bordeaux mixture is highly beneficial but the formaldehyde treatment is to be preferred. The latter treatment will cost about two-thirds of one cent per seedling. 20. Bordeaux mixture (4-4-50) is quite effective in preventing seedling blight. The treatment is too expensive and therefore inapplicable under ordinary conditions. Bordeaux mixture may be of practical application where labor cost is reduced. The safest and cheapest control measure is to grow healthy seedlings and set them on in uninfested soils.

The COVID-19 pandemic has affected all aspects of healthcare. The NHS has had to manoeuvre faster than ever before, which is remarkable for a huge organisation known to advance slowly and steadily. The adaptations have had both positive and negative impacts. There were also funding changes, in the form of temporary contractual arrangements. As the NHS plans for the future, an opportunity has arisen to fundamentally change the NHS funding structure.

This article will describe the effect of COVID-19 on healthcare finance, the challenges in developing a new payment structure, and the role that clinicians can play in helping shape funding arrangements in the future.

Abstract

Objectives: To observe the efficacy of platelet rich plasma on pain improvement in knee osteoarthritis patients, and to explore the impact of various facotrs on pain reduction with such a treatment.

Method: The quasi-experimental study was conducted at the Armed Forces Institute of Rehabilitation Medicine, Rawalpindi, Pakistan, from October 2017 to April 2018, and comprised patients with primary knee osteoarthritis. The sample was sub-grouped into “normal”, “overweight” and “obese” on the basis of body mass index. Two age-based sub-groups  were also formed at ?60 years and >60 years. Three injections of calcium gluconate activated 2.5ml platelet rich plasma were given in the knees at an interval of two weeks each. The pain score was calculated using the numerical rating scale at the 6th week. Data was analysed using SPSS 20.

Results: Of the 50 patients, 26(52%) were females and 24(48%) were males. The overall mean age was 59.6±9.6 years (range: 42-75 years), with 22(44%) aged ? 60 years. There were 21(42%) patients who were overweight, 7(14%) had normal weight and 22(44%) were obese. There was significant pain reduction post-treatment compared to the baseline (p<0.001). The reduction in pain was not significantly related to gender, age, knee osteoarthritis grade, or body mass index (p>0.05).

Conclusions: Platelet rich plasma significantly improved pain in knee osteoarthritis patients regradless of all age, gender, grade and body mass index.

Key Words: Intra-articular injections, Primary knee osteoarthritis, Platelet rich plasma, Efficacy.

16. VE 17. YÜZYIL AVRUPA RESİM SANATINDA ÇİÇEK İMGESİ VE KOKU ALEGORİSİ
Authors: BOYNUKALIN Azize Reva
Published: October 2020

Avrupa Resim sanatında 16. yüzyıl Hollandalı ve Flaman natürmort sanatçıları; her bitkinin çeşitli renk ve dokularını, çiçeklerin inceliğini, kök ve yaprağın organik ritimlerini hassas bir duyarlılıkla resmetmişlerdir. Yılın aynı zamanında çiçek vermeyen bitkileri hayali olarak tasarlayıp çiçek imgelerini sembolik ifadelere dönüştürmüşlerdir. Coğrafi keşifler ve yeni bulunan bitki türleri, botanik bilimindeki ilerlemeler, dört element üzerine yazılan resimli kitaplar gibi dünyayı tanıma doğrultusundaki tüm araştırmalar, çiçek imgelerinin sembolik anlatımını güçlendirmiştir. Ortaçağ resim sanatında teolojik bir metafor olan çiçek imgeleri, 16. yüzyıldan itibaren; resim sanatının doğa, edebiyat ve şiirle olan ilişkisine felsefi bir boyut kazandırmıştır. Avrupa’da 17.yüzyılda erken modernitenin belirleyiciliği ile duyu kavramına olan hümanistik ve bilimsel ilginin artmış ve çiçek imgeleriyle bağlantılı olarak çok sayıda koku alegorisi resimleri yapılmıştır. Duyular geleneksel rollerinden çıkarak dünyevi hazların ve nesnelleştirilen bedenin göstergelerine dönüşmüştür. Özellikle 17. yüzyıla ait çiçek resimleri ve koku alegorileri natüralist anlayışın da ötesinde kültürel bir alanı işaret etmektedir.Bu makale, 16. ve 17. yüzyıl Avrupa resim sanatındaki çiçek imgelerinin sembolik anlamlarının; teoloji, doğa bilimleri, edebiyat gibi farklı disiplinlere nasıl katkı sağladığını göstermeyi amaçlamaktadır. Ayrıca çiçek imgelerine bağlı olarak gelişen koku alegorisi resimleri analiz edilerek yeni bir bakış açısı ile ele alınmıştır.
