Role of PD-L1 in Oral Cancer: From the Perspective of Immuno-oncology
Authors: Khan Moomal Aslam
Published: March 2020

Oral cancers are prevalent in our region and their management requires an upgrade in terms of advanced techniques. Immunotherapy is a novel therapeutic approach across the world that has shown significance in the sphere of oncology. Tumor cells escape detection from the immune surveillance mechanism resulting in proliferation. Through cancer immunotherapy, body’s own immune defense mechanism is stimulated with the aid of immunomodulating drugs. Scientists are underway studying the tumor microenvironment where immune editing takes place resulting in tumor escape and evasion. Many immune checkpoint proteins are being studied for clinical implications, however, the immune checkpoint blockade of Programmed death ligand-1(PD-L1) has proven to be successful and FDA approved in certain tumors. Role of increased expression of PD-L1 in oral cancer has been explored with variable results. Most researches have related it with tumor progression and prognosis. This review focuses on the importance of PD-L1 as an emerging immune checkpoint inhibitor, emphasizing its expression in cancers, particularly in oral cancer. The information was retrieved from reliable search engines e.g. PubMed, Medline, Google scholar and others, through original research papers and reviews published hitherto, from 2010-2019. It is essential to explore advanced treatment modalities for oral cancer especially via immunotherapy. Furthermore, additional studies on PD-L1 expression in OSCC are required including standardized protocols to reach definitive conclusions for clinical implications.
The Nature and Frequency of Medical Emergencies in Dental Offices of Karachi, Pakistan
Authors: Niaz Ayesha Tariq
Published: March 2020

Background: Medical emergencies are an unfortunate part of the dental practice, to which the dentist must have the required knowledge and means to counter them. In this study, we aimed to determine the nature and frequency of medical emergencies occurring in the dental offices of Karachi, Pakistan. We also aimed to ascertain the awareness and preparedness of dentists and their attitude towards training in management of these medical emergencies.

Methods: In this study, 300 questionnaire forms were distributed to dentist at various colleges in Karachi city in the year 2015, out of which 244 complete and valid forms were received and used, giving a response rate of 81%. SPSS version 16.0 was used to compute and analyze the collected data.

Results: Out of 244 respondents, 23% were males and 77% were females. Since, 83% of the dentist had faced a medical emergency at least once in their practice. Highest recorded medical emergency was found to be syncope (faints) being reported by 71% of the dentist. Most of the medical emergencies (89%) took place during an extraction procedure. 55% dentist claimed that they were prepared enough to manage an emergency. Irrespective of their perceived abilities, 100% showed keen interest in the field of improvement through continuing education in management of medical emergency.

Conclusion: Medical emergencies are common in dental practice and a substantial proportion of dentists feel incompetent in handling such situations. This requires better medical emergency management courses and training in undergraduate dental programs as well as continued dental education and training.
Influence of Next-Generation Sequencing on Advancements in the Diagnosis of Major Psychiatric Diseases - A Review
Authors: Nisar Maheen
Published: March 2020

Rapid progress is being made in the development of next-generation sequencing (NGS) technologies, allowing repeated findings of new genes and a more in-depth analysis of genetic polymorphisms behind the pathogenesis of a disease. In a field such as psychiatry, characteristic of vague and highly variable somatic manifestations, these technologies have brought great advances towards diagnosing various psychiatric and mental disorders, identifying high-risk individuals and towards more effective corresponding treatment. Psychiatry has the difficult task of diagnosing and treating mental disorders without being able to invariably and definitively establish the properties of its illness. This calls for diagnostic technologies that go beyond the traditional ways of gene manipulation to more advanced methods mainly focusing on new gene polymorphism discoveries, one of them being NGS. This enables the identification of hundreds of common and rare genetic variations contributing to behavioral and psychological conditions. Clinical NGS has been useful to detect copy number and single nucleotide variants and to identify structural rearrangements that have been challenging for standard bioinformatics algorithms. The main objective of this article is to review the recent applications of NGS in the diagnosis of major psychiatric disorders, and hence gauge the extent of its impact in the field. A comprehensive PubMed search was conducted and papers published from 2013-2018 were included, using the keywords, “schizophrenia” or “bipolar disorder” or “depressive disorder” or “attention deficit disorder” or “autism spectrum disorder” and “next-generation sequencing”

Authors: Medvid Ya.
Published: March 2020

Goal. To evaluate the role of nectarines in attracting coccinellid in the agrocenosis of spring wheat.

Methods. Field experience on the effect of nectarines to attract coccinellid; accounting ladybirds on the plot of nectarines and sowing of spring wheat in accordance with standard methods; laboratory — determination of species composition of ladybirds. The study was conducted in the 2017—2019 years. at the experimental field of the National scientific center «Institute of agriculture of NAAS of Ukraine» in the Department of plant protection against pests and diseases (Kiev region, Kiev-Svyatoshinsky district, town Chabany).

Results. Updated the species composition of coccinellid in modern conditions on nectarines. Identified eight types of ladybirds, among which Coccinella septempunctata Linnaeus, 1758 and Hippodamia variegata Goeze, 1777 are the dominant species. Reflected seasonal population dynamics of ladybirds. Identified a high effect of attracting coccinellid on the dill, where their average number was much higher than on some other options. Given the average number of ladybugs on spring wheat during the accounting period.

Conclusions. Considering the useful role of representatives of the family Coccinellidae (Latreille, 1807) on crops, it is necessary to improve the practical use of entomophages and engaging coccinellid in agrocenoses with overseeding nectarines. Culture that attracts the entomophagous defined by dill (40.0 specimen/100 sweep net). More diverse species composition was observed coccinellid on Vick spring (six species). The average number of ladybirds over the growing period of spring wheat amounted to: land adjacent to nechernozeme to 16.7 ind./100 sweep net, control of 9.4 ind/100 sweep net. Such an advantage underscores the need of interplanting of plants that attract coccinellid in agrocenoses.

Hereditary Semiorders and Enumeration of Semiorders by Dimension
Authors: Keller Mitchel T. , Young Stephen J.
Published: March 2020

In 2010, Bousquet-Mélou et al. defined sequences of nonnegative integers called ascent sequences and showed that the ascent sequences of length $n$ are in one-to-one correspondence with the interval orders, i.e., the posets not containing the poset $\mathbf{2}+\mathbf{2}$. Through the use of generating functions, this provided an answer to the longstanding open question of enumerating the (unlabeled) interval orders. A semiorder is an interval order having a representation in which all intervals have the same length. In terms of forbidden subposets, the semiorders exclude $\mathbf{2}+\mathbf{2}$ and $\mathbf{1}+\mathbf{3}$. The number of unlabeled semiorders on $n$ points has long been known to be the $n$th Catalan number. However, describing the ascent sequences that correspond to the semiorders under the bijection of Bousquet-Mélou et al. has proved difficult. In this paper, we discuss a major part of the difficulty in this area: the ascent sequence corresponding to a semiorder may have an initial subsequence that corresponds to an interval order that is not a semiorder.

We define the hereditary semiorders to be those corresponding to an ascent sequence for which every initial subsequence also corresponds to a semiorder. We provide a structural result that characterizes the hereditary semiorders and use this characterization to determine the ordinary generating function for hereditary semiorders. We also use our characterization of hereditary semiorders and the characterization of semiorders of dimension $3$ given by Rabinovitch to provide a structural description of the semiorders of dimension at most $2$. From this description, we are able to determine the ordinary generating function for the semiorders of dimension at most $2$.
Stability for Maximal Independent Sets
Authors: Kahn Jeff , Park Jinyoung
Published: March 2020

Answering questions of Y. Rabinovich, we prove "stability" versions of upper bounds on maximal independent set counts in graphs under various restrictions. Roughly these say that being close to the maximum implies existence of a large induced matching or triangle matching (depending on assumptions).

A mild strengthening of one of these results is a key ingredient in a proof (to appear elsewhere) of a conjecture of L. Ilinca and the first author giving asymptotics for the number of maximal independent sets in the graph of the Hamming cube.
Constructions for the Elekes–Szabó and Elekes–Rónyai problems
Authors: Makhul Mehdi , Roche-Newton Oliver , Warren Audie , De Zeeuw Frank
Published: March 2020

We give a construction of a non-degenerate polynomial $F\in \mathbb R[x,y,z]$ and a set $A$ of cardinality $n$ such that $F$ vanishes on $\Omega(n^{3/2})$ points of $A \times A \times A$, thus providing a new lower bound construction for the Elekes–Szabó problem. We also give a related construction for the Elekes–Rónyai problem restricted to a subgraph. This consists of a polynomial $f\in \mathbb R[x,y]$ that is not additive or multiplicative, a set $A$ of size $n$, and a subset $P\subset A\times A$ of size $\Omega(n^{3/2})$ on which $f$ takes only $n$ distinct values.
Lozenge Tilings of Hexagons with Central Holes and Dents
Authors: Lai Tri
Published: March 2020

Ciucu proved a simple product formula for the tiling number of a hexagon in which a chain of equilateral triangles of alternating orientations, called a `fern', has been removed from the center (Adv. Math. 2017). In this paper, we present a multi-parameter generalization of this work by giving an explicit tiling enumeration for a hexagon with three ferns removed, besides the central fern as in Ciucu's region, we remove two new ferns from two sides of the hexagon. Our result also implies a new `dual' of MacMahon's classical formula of boxed plane partitions, corresponding to the exterior of the union of three disjoint concave polygons obtained by turning 120 degrees after drawing each side.

Projections of Antichains
Authors: Janzer Barnabás
Published: March 2020

A subset $A$ of $\mathbb{Z}^n$ is called a weak antichain if it does not contain two elements $x$ and $y$ satisfying $x_i<y_i$ for all $i$. Engel, Mitsis, Pelekis and Reiher showed that for any weak antichain $A$, the sum of the sizes of its $(n-1)$-dimensional projections must be at least as large as its size $|A|$. They asked what the smallest possible value of the gap between these two quantities is in terms of  $|A|$. We answer this question by giving an explicit weak antichain attaining this minimum for each possible value of $|A|$. In particular, we show that sets of the form $$A_N=\{x\in\mathbb{Z}^n: 0\leq x_j\leq N-1 \textrm{ for all $j$ and } x_i=0\textrm{ for some $i$}\}$$ minimise the gap among weak antichains of size $|A_N|$.
The Impact of Online Training on Saudi Medical Students’ Attitudes, Awareness, and Use of Language Learning Strategies in Relation to their Developing Autonomy
Authors: Alzahrani Sahar , Watson Julie
Published: March 2020

In the context of ongoing debate about the relationship between strategy training and autonomous learning, this study set out in the belief that they are inextricably linked and sought to explore three important aspects of learner strategy development more deeply. An experiment was designed to investigate the effectiveness of learner training with three groups of Saudi students taking a course in English for Medical Purposes: control (no treatment), offline (treatment delivered on paper), and online (online treatment). The treatments used supplementary learning material focused on language learning strategies (LLS). The design and the delivery of the treatments was informed by Rubin, Chamot, Harris, and Anderson (2007), Cohen (1998), Murphy and Hurd (2011), and Murphy (2008a). This paper sought to answer three research questions related to the impact of learner training on students’ attitudes, awareness, and use of LLS in relation to their autonomous abilities after exposure to the treatment. Qualitative data from students’ reflective writings, interviews and focus group discussion was used to answer these questions. For the two treatment groups, the treatment impact was found to be positive in relation to the research questions and negative in the control. The online group outperformed the offline one in all the three investigated aspects.
Age and architecture of the largest African Baobabs from Mayotte, France
Authors: Patrut Adrian , T. Patrut Roxana , Rakosy Laszlo , Von Reden Karl F.
Published: March 2020

The volcanic Comoro Islands, located in the Indian Ocean in between mainland Africa and Madagascar, host several thousand African baobabs (Adansonia digitata). Most of them are found in Mayotte, which currently belongs to France, as an overseas department. Baobabs constitute a reliable archive for climate change and millennial specimens were recently used as proxies for paleoclimate reconstructions in southern Africa. We report the investigation of the largest two baobabs of Mayotte, the Big baobab of Musical Plage and the largest baobab of Plage N’Gouja. The Big baobab of Musical Plage exhibits a cluster structure and consists of 5 fused stems, out of which 4 are common stems and one is a false stem. The baobab of Plage N’Gouja has an open ring-shaped structure and consists of 7 partially fused stems, out of which 3 stems are large and old, while 4 are young. Several wood samples were collected from both baobabs and analyzed via radiocarbon dating. The oldest dated sample from the baobab of Musical Plage has a radiocarbon date of 275 ± 25 BP, which corresponds to a calibrated calendar age of 365 ± 15 yr. On its turn, the oldest sample from Plage N’Gouja has a radiocarbon date of 231 ± 20 BP, corresponding to a calibrated age of 265 ± 15 yr. These results indicate that the Big baobab of Musical Plage is around 420 years old, while the baobab of Plage N’Gouja has an age close to 330 years. In present, both baobabs are in a general state of deterioration with many broken or damaged branches, and the Baobab of Plage N’Gouja has several missing stems. These observations suggest that the two baobabs are in decline and, most likely, close to the end of their life cycle.

Trabajo de investigación de tesis de Licenciatura en Ingeniería en Producción Animal de la USMA. Ríos L. 2015

El objetivo del estudio fue caracterizar el manejo del ordeño en fincas doble propósito del distrito de Los Santos. Se recolectó información a partir de una muestra probabilística de 46 productores, a través de encuestas semiestructuradas y observación directa, durante el periodo marzo-junio 2014. La información comprendió aspectos socio-económicos, características de las fincas y del manejo al ordeño. Los datos se analizaron empleando estadísticas descriptivas. Se determinó que 72% de los productores no lavan la ubre de la vaca al momento del ordeño. La mayoría apoya a sus vacas con ternero, un 7% utilizan inyección (oxitocina) para el apoyo. El 89% realizan el secado de la ubre al momento del ordeño, pero con prácticas inadecuadas, como el secado de los pezones con el rabo de la vaca. La infraestructura para el ordeño consiste en galera con piso para el 35% de los productores, 33% disponen de galera pero sin piso, y 33% ordeñan en el corral. El 80% realiza la higiene de utensilios utilizados después del ordeño (coladeras, garrafones, cubos, pezoneras y paños de limpieza). El 96% limpian los garrafones de leche todos los días. El 35% indicaron tener problemas de mastitis, relacionada princi-palmente al ordeño mecanizado. Se concluye que los productores mostraron inadecuadas prácticas de manejo tanto en la higiene de la ubre como en el tipo de infraestructura, situación que puede llegar a comprometer la calidad del producto y la productividad de su hato.

Published: March 2020

Different currencies are being processed in money exchange shops and banks around the globe on a daily basis, where money exchange and transfer takes place. Identifying different currency is a difficult task and can lead to financial loss. There are approximately 180 currencies being used around the world, and each of them differ in color, size and texture. Thus, to correctly identify different currencies, a currency recognition systems needs to be designed. In this paper, we propose the design of an AlexNet based currency recognition system to recognize different international currency notes. We use 10-fold Cross Validation to obtain the cross-validation results of the AlexNet model. The features for the Alex model is extracted from the images back and front of each currency note. We also explore and implement deep learning models to compare the performance of the AlexNet model.

Published: March 2020

An investigation on some methods for the incorporation of phase change materials (PCMs) into concrete and their effect on its properties is presented. PCMs are characterized by high latent fusion heat, which can increase thermal mass of concrete and contribute to the bioclimatic design of buildings. Concrete compositions with different aggregates (limestone, lightweight or their combination), as well as with different PCMs (paraffinic and dodecyl alcohol) were prepared by different incorporation methods (impregnation to lightweight aggregates or immersion of concrete specimens). Properties of fresh and hardened concrete were studied, as well as hydration heat, thermal response and flammability. The results revealed that the selected PCMs do not significantly affect the properties of concrete. Regarding hydration heat, the presence of the PCM in concrete contributes to a decrease of the temperature peak during hydration which also occurs delayed. Thermal response measurements showed that concrete with purely pumice aggregates has a much better thermal behavior than the other two compositions, while the existence of PCM causes large or small increase of concretes heat capacity, in temperature near to each PCM’s melting point. Finally, appropriate application of PCMs is needed in order to moderate the reported effect on concrete’s fire resistance
A NOTE ON PROPERTIES OF EXPONENTIAL POWER DISTRIBUTION
Authors: Olosunde Akinlolu
Published: March 2020

The most common generalization of the normal, Kotz-symmetric and double exponential distribution functions was the exponential power distribution. This distribution had been found useful in modeling real life data as studied in the literature. The present study found it necessary to fill the void in the literature by presenting some properties which characterized exponential power distribution and further made it useful in applications.
RADIOTHERAPY IN COMBINED TREATMENT OF RECURRENT STAGE 3 LARYNGEAL CANCER
Authors: Asadli Geis
Published: March 2020

The paper presents the treatment results performed in 250 patients with a laryngeal tumor of the third stage. The average life expectancy of these patients generally does not exceed 3−6 months. Chemotherapy is usually considered the standard treatment for the recurrence of head and neck squamous cell cancer patients, previously received radiotherapy. When prescribing the chemotherapy, a tumor regression is observed only in 10−40 % and does not virtually affect the life. Average life expectancy of these patients often varies from 5 to 9 months. The optimal total dose of radiotherapy for the treatment of inoperable recurrent and metastatic cancer was found in this reserach for imroving treatment results. The surgical protocols and techniques under discussion in this paper are certainly of a practical significance. The method for preoperative radiotherapy for larynx cancers was developed and the guidelines have been proven. Also there was proven that preoperative radiotherapy in a combined treatment of recurrent operable laryngeal cancer increases its effectiveness and does not affect postoperative period. Repeated radiotherapy for recurrent inoperable laryngeal cancer is possible only if the changes after previous radio− or combination therapy do not exceed 2 degrees. In addition, a repeated radiotherapy at a total source dose of 40−60 Gy is an effective method of palliative treatment and significantly improves the life expectancy and quality in the patients if compared with palliative chemotherapy. The method used in combination with intratumoral chemo− and radiotherapy significantly improves the efficiency of palliative treatment in the patients with recurrent regional metastasis for inoperable laryngeal cancer, in the primary tumor area, no signs of recurrence were found.

Key words: laryngeal cancer, combined cancer treatment, radiotherapy.
COGNITIVE IMPAIRMENT IN NEURODEGENERATIVE PATHOLOGY AS INDEX OF NEUROPLASTICITY IN PSYCHONEUROLOGICAL MODEL OF ADAPTATION OF PATIENTS
Authors: Chernenko Maksim Yevgenevich
Published: March 2020

Today, cognitive function and their impairment in patients with neurodegenerative diseases is an urgent problem of modern neurology. The study of the neuropsychological profile makes it possible to more accurately present the picture of involvement in the pathological process of different brain structures and thereby facilitate differential diagnosis. In order to study the cognitive features of patients with neurodegenerative (demyelinating) pathology and the possibility of their psychoneurological adaptation, 104 patients with remitting type of multiple sclerosis were examined. To investigate verbal memory disorders, we used the method of "Remembering 10 words", which allows to evaluate such parameters as the amount of direct memory and the strength of delayed memory (ie indicators of short and long−term memory). The Schulte Tables technique was used to investigate arbitrary attention disorders, enabling the evaluation of arbitrary attention as volume, concentration distribution functions, and attention switching. It is concluded that the assessment of cognitive deficits as for personal characteristics and emotional, volitional disorders significantly reduces the informativeness and the ability to correct cognitive dysfunction. Thus, in severe remission multipple slerosis in women was more pronounced than in men, as well as a lack of ability to work and attention deficit.The revealed neurodynamic and operative disorders make it possible to draw conclusions about the severity of the neurodegenerative process and its prognosis.Timely detection of cognitive and emotional−personality changes can not only improve the life quality of patients with neurodegenerative diseases, but also act as an independent link in psychoneurological model of adaptation of these patients.

Key words: neuroplasticity, adaptation, neurodegenerative pathology, demyelination, cognitive dysfunction.
FEATURES OF OPHTHALMIC CARE FOR PATIENTS WITH COMPLICATED CATARACTS
Authors: Lapkina Inna Ivanovna
Published: March 2020

Today, around 50 million people worldwide suffer from cataracts, more than a half of them need surgical treatment. High prevalence of this pathology in Ukraine, the need to improve the provision of ophthalmic care to patients, and the reform of the health care system have made the research relevant. Concomitant diseases and special conditions of the eye increase the risk of intra− and postoperative complications, worsen the functional parameters of patients after surgery. In order to develop a unified approach to the treatment of complicated cataracts based on diagnostically related groups of patients, a retrospective analysis of case histories of patients with different variants of complications related to the condition of the lens itself, its ligament apparatus and other structures of the eye was conducted. In each case, the surgeon has to choose the appropriate modification of cataract phacoemulsification surgery. The study proposed the classification of cataract phacoemulsification modifications on the basis of the techniques and the sequence of operation stages, taking into account the classification of the degrees of turbidity of the lens, proposed by L. Buratto. It has been noted that in complicated cases, according to the indications of the patient, surgery may be performed on several modifications of cataract phacoemulsification. The developed classification made it possible to generalize the various variants of pathology and greatly facilitate the choice of tactics of surgical treatment in complicated cataracts. It can be used not only for practical application, but also for improving the qualification of trained professionals. The prospect of further research is to identify contraindications for outpatient treatment of the patients with complicated cataracts.

Key words: cataract complication, classification of phacoemulsification modifications, diagnostically related groups.
EXPERIENCE OF AFLIBERCEPT APPLICATION IN PATIENTS WITH EXUDATIVE AGE-RELATED MACULAR DEGENERATION
Authors: Konovalova Darina Aleksandrovna
Published: March 2020

Age−related macular degeneration is a threatening pathology, gradually leading to a complete loss of central vision, which adversely affects an individual physically and emotionally as well as socially, reducing the life quality of such patients. To analyze the anatomical and functional results of intravitreal injections of aflibercept in the patients with exudative age−related macular degeneration, 47 patients a were prospectively studied. Intravitreal injections of aflibercept were performed by the same surgeon under aseptic operating conditions at a dosage of 2 mg, which was 0.05 ml of the drug. All patients underwent a comprehensive ophthalmic examination, which included visometry, autoceratorefractometry, tonometry, biomicroscopy, and ophthalmoscopy under medical mydriasis, as well as optical coherence tomography. The study took place before the intravitreal administration of aflibercept, one month after each of the three loading injections, 4, 8, and 12 weeks, respectively, after the start of treatment, and 4 weeks after the fourth injection, which was performed 8 weeks after the third loading. The total follow−up period was 24 weeks. For assessing the anatomical and functional efficiency of the treatment the changes in visual acuity, which were adjusted as well as those in the central retinal thickness according to optical coherence tomography were accepted as the criteria. The treatment results showed a significant increase in visual acuity of patients with the most significant increase in the index at week 12 from the beginning of therapy, as well as to a statistically significant decrease in the central retinal thickness within six months of observation. It is obvious that a consistent use of this drug is necessary to achieve stable treatment results.

Key words: exudative age−related macular degeneration, visual acuity, central retinal thickness, intravitreal antiangiogenic therapy.
Yes/no questions as conversational expanders: Their effects on discourse and identity-in-interaction
Authors: Nakamura Ian
Published: March 2020

This paper explores how yes/no questions work as conversational expanders, and therefore impact on discourse and identity-in-interaction. Two interactional contexts are examined, a celebrity interview and a teacher-student conversation. Transcripts of these conversations reveal that the interviewer and teacher offer confirmation-seeking questions as a means of identifying worthwhile topics, while the interviewee and student use them to disclose new information. While it can be argued that their identities as teacher and student do not really change through these actions, what these participants do display is an adjustment of their turn-by-turn discourse identities that helps maintain the conversation. Such interactional work reminds us that situated identities such as teacher/student and language expert/novice are not rigidly predetermined, but negotiated and reaffirmed on a turn-by-turn basis.

この論文はYes/No questionがどのようにして会話を展開し談話やディスコース・アイデンティティに影響を与えるかを孝察するものである。有名人のインタビューと教師-生徒間の会話の二種類の対話において、単なるYes/No以上の会話へと拡充するために、参加者がどのようにYes/No questionを利用するかを調査した。使用例によると、インタビュアーや教師は適切な話題を探しだす手段としてyes/no questionを使うのに対し、インタビュイーと生徒は情報を得るために使っていることが分かった。教師—生徒というアイデンティティ（役割）がこの会話で変化するのではないが、参加者たちは会話を継続させるためにターン交代の度にディスコース・アイデンティティを調整していく。会話において進行中の話題を広げていくその作業は、言語専門家（教師）が質問し素人（生徒）が答える、といった単純明快な関係以上のアイデンティティの動きを示唆するものである。
The Socratic trap: A strategic snare that EFL teachers should sidestep
Authors: de Boer Mark
Published: March 2020

Teachers use a variety of questions and feedback to facilitate communication in the classroom. One type of questioning strategy uses Socratic type questions to lead the students to a pre-formulated answer. Through examination of classroom discourse, this paper shows that in the EFL classroom, this type of questioning strategy may not be ideal for promoting communication.

教師はクラスでのコミュニケーションが円滑に行われる様に、様々な質問やフィードバックを使用する。その戦略の一つが、前もって処方された答えに学生を導くソクラテスの問答法である。本論では、クラス内ディスコースの調査を通して、EFLクラスではソクラテスの問答法がコミュニケーションを促進するのに理想的ではないかも知れないと述べている。
Identity in interculturality: Using (lack of) cultural knowledge to disalign with an identity category
Authors: Greer Tim
Published: March 2020

This article focuses on the notions of interculturality and identity. It outlines some of the ways in which identities can be made relevant in conversation when interactants orient to certain items of cultural knowledge that are normatively bound to those identity categories. By analyzing a brief instance of naturally-occurring talk, the study shows how identities are used as interactional resources to help accomplish social actions such as providing an account or disagreeing, in addition to aligning and disaligning with other people.

本稿では、interculturality(間文化性)の概念に焦点を合てる。対話の参加者が、一連の会話の中でどのように国民性アイデンティティを表象するのか、その経路を詳細に考察する。このようなアイデンティティは、あるカテゴリと密接に関連した文化的知識を参加者自身が適応することで具現化される。実際の自然会話のある断片を分析することで、アイデンティティが他者とのに協調・不協調、「理由付け」「意見の相違の示唆」などといった社会的行為の達成を促す相互作用のリソースとして使用されること実証する。
Curriculum Negotiation at NHK: Meeting the Needs and Demands of Adult Learners
Authors: Harris Harry
Published: March 2020

Curriculum negotiation, the act of teacher-student collaboration to determine a syllabus, is a procedure that various researchers have explored and explained. This writer has engaged in this process in NHK Culture Center English classes because of the great variety in the language needs and personal demands of his students and other institution-related conditions. It is argued that this alternative pedagogical practice can successfully allow mature students to create their own curriculum responsibly, making the learning process more meaningful and interesting to them. It is also suggested that the methodology herein described may be adaptable to other second language learner contexts.

シラバスを決める為の教師と生徒の協力活動である、カリキュラム交渉は様々な研究者が調査し、説明している方法である。本著者は、NHK文化センターの英語クラスでと又関連した他の教育機関で、英語を必要とする多様性と生徒の個人的な要求の為に、この方法に関わった者である。教育上の選択肢の練習が、成長した生徒に学習過程をより意味があるものとし、彼等により興味をもたせながら、責任をもって彼等自身のカリキュラムを上手く創造させることができるかを論じるものである。ここに述べる方法論が他の第二言語学習者の状況にも取り入れられるかもしれないことも又提案するものである。
