Résumé :

There is a group of artists in contemporary Azerbaijani fine arts, whose creative works focus on the theme of Absheron. For half a century, this theme has defined the style of most of our artists with its specificity, rich ethnography, national harmony and lyrics. Jalal Aghayev is one of such artists, and the theme of Absheron covers a large part of his creative work. The inexhaustible love for the land of Absheron has been rooted in the artist's heart since childhood. This love led the artist to create a series of beautiful works on this subject. Key words: landscape, Absheron, painting, tradition, plot, composition, decorative

Résumé :

Abstract Background Tattoo artists are an understudied population with regards to musculoskeletal (MSK) pain. Aims To explore the characteristics of MSK pain among Israeli tattoo artists and determine whether they are similar to those of dental workers. Methods An online survey including demographics and the Hebrew version of the Extended Nordic Musculoskeletal Questionnaire was disseminated via Israeli social media groups. We directly compared tattoo artists, dental workers and office workers as a reference group. Results Altogether, 114 tattoo artists, 161 dental workers and 296 office workers responded. The most prevalent pain sites were lower back (56%), neck (47%) and hand (36%) among office workers; neck (67%), lower back (62%) and upper back (42%) among the dental workers; and lower back (72%), neck (66%) and hand (55%) among tattoo artists. Contrast analysis suggested office workers were less likely to report pain in the previous 12 months compared with dental workers and tattoo artists (adjusted odds ratios [95% confidence intervals]: ORs [95% CIs] for upper limb pain: 1.13 [1.01–1.28], neck pain: 1.3 [1.15–1.47], upper back pain: 1.27 [1.12–1.43] and low back pain: 1.15 [1.02–1.3]). No significant differences were observed between dental workers and tattoo artists (upper limb pain: 1.18 [0.9–1.54], neck pain: 1.06 [0.81–1.4], upper back pain: 1.22 [0.94–1.58] and low back pain: 1.24 [0.95–1.64]). Conclusions Tattoo artists and dental workers have similar MSK pain characteristics and are different from those of office workers. These characteristics are seemingly a direct result of the physical demands associated with their line of work.

Résumé :

The K-pop music industry is signified by a hyper-competitive training system. The aim was to examine dropout and retention rates among a representative sample of K-pop artists and groups. The dropout rates of 49 K-pop groups and 298 group members (N = 298; F = 130; M = 168), who have been active any time between 2003–2019, were 5.70%. As gender, age and other generic control factors could not explain more than a fraction of retention rates, the author interprets this as partial evidence for melancholia among some dropouts.

Résumé :

The purpose of this autoethnographic study is to examine the experiences of visual arts educators who identify themselves as Artist Educators. In particular, this article investigates how these Artist Educators perceive the fusion of their artistic studio practice with their teaching pedagogy, and how the perception defines their identity and impacts their creative and classroom practices. This study involved a focus group of six individuals, including the researcher. All the participants were practising artists, currently employed or recently retired K-12 visual arts educators certified in the states of Maine or New Hampshire, and members of the Kittery Art Association. This study used a combination of interviews and an arts-based method for data collection. All the data were analyzed and resulted in seven findings that culminated in the Way of the Artist Educator ‐ an alternative paradigm for a quality and holistic twenty-first-century visual arts education. This article presents the paradigm, discusses the study’s implications and offers suggestions for future research.

Résumé :

Korean Pop or K-Pop is part of the hallyu wave. K-Pop music consists of many artists. Fans of each artist gathered and formed a group called fandom. Each fandom has a culture that distinguishes one fandom from another. Symbol is a form of message that contains meaning. Through the interaction between group members, symbols can be formed. Fandoms have their own culture and symbols are included in their culture. BTS and EXO are in the top 30 most popular K-Pop boy bands since June 2021. BTS fans named ARMY and EXO fans named EXO-L. Both fandoms have symbols that become cultural and have different forms and meanings. This research was conducted because there is no research that discusses the comparison of symbols between the two K-Pop fandoms and the process of these symbols entering the fandom so that they become culture. The theory used in this research is the theory of cultural communication and symbolic interaction. The study used a descriptive qualitative research approach with fenomenology research methods. The research data were obtained from in-depth interviews, participant observation, documentation, and literature study of four sources. The results show that symbols enter through the process of cultural communication and the same form and meaning of symbols from the ARMY and EXO-L fandoms can be created through communication between artists and fandoms or between fandom member. Korean Pop atau K-Pop adalah bagian dari hallyu wave. Musik K-Pop terdiri dari banyak artis. Penggemar tiap artis berkumpul dan membuat sebuah kelompok yang bernama fandom. Tiap fandom mempunyai budaya yang membedakan satu fandom dengan yang lainnya. Simbol merupakan salah satu bentuk pesan yang mengandung makna. Melalui interaksi antar anggota kelompok, simbol dapat terbentuk. Fandom mempunyai budaya sendiri dan simbol termasuk kedalam budaya mereka. BTS dan EXO masuk ke dalam 30 peringkat boy band K-Pop terpopuler sejak Juni 2021. BTS bernama ARMY dan penggemar EXO bernama EXO-L. Kedua fandom memiliki simbol yang menjadi budaya serta memiliki bentuk dan makna yang berbeda. Penelitian ini dilakukan karena belum ada penelitian yang membahas mengenai perbandingan simbol antara dua fandom K-Pop serta proses simbol tersebut masuk kedalam fandom sehingga menjadi budaya. Teori yang digunakan dalam penelitian ini adalah teori komunikasi budaya dan interaksi simbolik. Penelitian menggunakan pendekatan penelitian kualitatif deskriptif dengan metode penelitian fenomenologi. Data hasil penelitian diperoleh dari hasil wawancara mendalam, observasi berperan serta, dokumentasi, dan studi kepustakaan. Hasil penelitian menunjukkan bahwa simbol masuk melalui proses komunikasi budaya serta bentuk dan makna yang sama terhadap simbol dari fandom ARMY dan EXO-L dapat dibuat melalui komunikasi diantara artis dan fandom atau antar anggota fandom.

Zitzewitz, Karin. « Turning to the Goddess : Anachronism, Secularity, and the Late Style of Tyeb Mehta and K. G. Subramanyan ». ARTMargins 3, n^o 3 (octobre 2014) : 45–67. http://dx.doi.org/10.1162/artm_a_00092.

Texte intégral

Résumé :

At nearly the same late-1980s moment, two of the most important artists of India's twentieth century, Tyeb Mehta (1925–2009) and K. G. Subramanyan (b. 1924), turned to the goddess as a subject for painting. Although Mehta and Subramanyan represented different strands of Indian modernism, they had both hitherto largely limited themselves to secular subject matter. This essay accounts for the significance of their goddess turn by discussing it as an example of late style, as theorized by Edward Said. It finds in these paintings the intransigence, anachronism, and negative intervention championed by Said, but also a critique of the secularism that he argued was the root of late style. Mehta and Subramanyan's intervention came at a crucial moment in Indian art history, as modernism began to be undermined by a rising group of narrative painters supported by the critic Geeta Kapur. The older artists’ embrace of the religious image sits uneasily in Kapur's influential narration of post-colonial Indian art history.

Résumé :

We analyze four online concerts by K-pop group BTS (Bangtan Sonyeondan) during the COVID-19 pandemic (2020 to the present) from the view of participant observation. The pandemic served as a catalyst for the evolution of these concerts. BTS set new records for revenue generated by a single online concert in June 2020, only to beat their own record in October 2020, and again in June 2021. While BTS delivered high-quality online concerts to its fans, known as ARMY, these concerts highlighted the challenges to both audience members and performers despite the use of “virtual reality” technologies. We argue that BTS’s online concerts represent a new type of concert production and consumption that expands the accessibility of performances to fans all over the world, and also enabled new forms of interactions between artists and audience members. However, these concerts inadvertently highlighted the importance of in-person interaction between fans and performers as K-pop relies heavily not only on cheering and banners that support artists, but also on light sticks, fan chants, and other activities.

Résumé :

The author examines similarity of historical and cultural development of Russia and Scandinavian countries. Cultural ties between the two domains evolved over many centuries. The most intensive period of development of Russian-Scandinavian artistic contacts stretched from mid-1880s-1890s up to the end of the first decade of the 20th century. In 1890s Russian painters considered achievements of Scandinavian colleagues as an example of a quest for progress, a creative approach to finding ones way in development of fine arts. At the same period in Russia a number of major international art exhibitions were arranged with active northern painters participation. The Russian interest in the art of Scandinavian countries in the late 19th - early 20th c. was anything but accidental. The development of artistic culture in Nordic countries was in tune with the Russian artists quest for other ways of creative expression. Northern culture attracted sympathy of Russian painters, black-and-white artists and art critics of diverse, often opposing groups and movements. For example, among the admirers of Scandinavian fine arts were V.V. Stasov and A.N. Benoit, I.E. Repin, V.A. Serov, F.A.Malyavin, the artists of the "Mir iskusstva group, and representatives of Moscow School of Painting (K. Korovin, A. Arkhipov, V. Perepletchikov etc.). By mid-1890s relations of Russian and Scandinavian art schools had become very intense and productive. This interaction coincided with significant events that influenced further development of artistic and other forms of culture on both sides. It manifested itself in publications of works of A. Strinberg and K. Hamsun in Russian, in staging of H. Ibsens plays at the Moscow Art Theater, exhibitions (especially of A.Tsorns works), and other activities that served to cross-fertilisation of cultures of Russia and Scandinavian countries.

Résumé :

This article dials with the analysis of work of writers that belonged to the group of “Zievonia” through the prism of critic literary views of the Polish critic М. Grabovskyj. Determined, that the most obvious poetic capabilities М. Grabovskyj recognized in J. Borkovskyj and D. Magnushevskyj, but the special writer talent for the adopted artists of criticisms did not educed. М. Grabovskyj distinguished two incomparable translators of ancient and folk works – L. Semenskyj and А. Belyovskyj, their translations, thought the artist, considerably enriched Polish literature. М. Grabovskyj estimated very high ancient labours of K. Vojchitskyj, his collection of proverbs, parables, songs, legends critic considered as a large treasure of Polish literature, that had to influence on evolution of polish literary positively and mightily. But this figure was estimated ambiguously: as a collector of folklore K. Vojchitskyj was enough highly perceived by М. Grabovskyj, however did not saw him as a writer. Also L. Semenskyj was marked by M. Grabovskyj as a “not so good” writer, but as a translator of the greatest level. Thus, to «Zievonchyks» were heard not only dithyrambs but also objective estimations of work. Among all representatives of group «Zievonchyks» separate attention of М. Grabovskyj was dedicated to S. Goshchynskyj as one of its brightest representatives, that partly, to our opinion, was determined by the long-term friendship of both masters. M. Grabovskyj noticed that S. Goshchynskyj had unsurpassed ability to pass the mood of work by descriptions of landscape and he did not have competitors of this ability even among the representatives of Polish literary of that time. Poetic school «Zievonchyks» was distinguished by admiration of slavs, and adopting of paints of the folk Slavic poetry. М. Grabovskyj sympathized with slavs tendencies in works of many representatives of this group, and Grabovskyj estimated positively.

Résumé :

The Korean wave, the influence and spread of Korean culture in European and American countries The Korean wave, especially over the past few years, has had a significant impact on the world. More and more people have begun to be interested in the culture of South Korea to a greater or lesser extent. Some people are interested only in K-pop or Korean series, but there are many people who expand their interest in Korean culture, start learning the language, history, and customs. Of all aspects of South Korean culture, K-pop is certainly the most popular. Much more artists organize concert tours for the benefit of European countries and America, in 2019, in Poland there were 15 such concerts. More and more often, Korean food festivals, stationary stores selling Korean cosmetics and food products are organized, in some countries, there even appear themed dance schools focusing on learning specific K-pop dance arrangements. The Korean wave also affects the perception of beauty by people – in 2018, on the annual list of the most handsome men, there appeared much more Koreans than in previous years, even members of the BTS group occupy the first places on the list.

Résumé :

Introduction. The article discusses the problem of developing ethnic onstage costumes for folk bands. The steps of the development of the design project of the Udmurt onstage ethnic costume for the in the studio of the artists are based on the materials found in the books on folk clothing. It also considers the involvement of the students from the Institute of Arts and Design of the Udmurt State University. Materials and Methods. The study is based on modern research on the Udmurt national costume, summarized in the works of specialists studying the national costumes of the Finno-Ugric peoples, primarily M. K. Zavyalova and S. Kh. Lebedeva. The article employs general research methods such as system analysis, comparison, semantic analysis, as well as an integrative method. Results and Discussion. The Udmurt national female costume is characterized by such features as sacredness and symbolism. Women’s clothing is streaked with symbols. From ancient times, the Udmurts endowed clothes with magical properties reflected in the ornament. The study of the history of the national costume as an integral part of the life of an ethnic group is a very important cultural task. The research by of S. Kh. Lebedeva and M. K. Zavyalova considered the main source of ideas for the creation of design projects for the onstage costumes, made by the artist, the author of the article, for the Udmurt folk band “Њardon” and the Cultural and Tourist Center “Tol Babai Estate”. The students of the Institute of Arts and Design of the Udmurt State University took an active part in this process. Conclusions. At present, the Udmurt national costume has practically disappeared from the everyday life of this ethnic group. Under such conditions, the importance of research by ethnographers, the specialists in costumes, art critics, and historians is increasing. An important contribution to the preservation of national culture is made by folk art bands. A variety of stage costumes is achieved by the work of a costume designer.

Résumé :

One of the current promotional strategies adopted by many brands in Indonesia is leveraging the K-Wave (Hallyu) phenomenon. A skincare manufacturer aims to capitalize on this opportunity by appointing the popular K-Pop girl group, Twice as their brand ambassador. The significant investment in this collaboration raises high expectations for skincare products, particularly regarding their chosen brand ambassadors' impact on purchasing decisions and brand loyalty. Hence, this research aims to examine the influence of various dimensions (visibility, credibility, attractiveness, and power) of K-Pop artist Twice on skincare product consumers' purchasing decisions and brand loyalty. Furthermore, the study aims to investigate the mediating role of customer satisfaction in the relationship between purchasing decisions and brand loyalty among cosmetics product consumers. This research employs a non-probability purposive sampling technique, with a sample size of 200 respondents aged between 15 and 34 years, encompassing all genders. The respondents must have prior experience using cosmetics products and be aware of Twice as one of the skincare brand ambassadors. The data analysis technique employed is the Structural Equation Modeling (SEM) Partial Least Squares (PLS) method. The findings indicate that the dimensions of "visibility" and "power" have a positive yet insignificant effect on purchasing decisions, while "credibility" and "attractiveness" exhibit a positive and significant impact on purchasing decisions. Additionally, the "visibility" dimension of the brand ambassador demonstrates a positive and significant influence on brand loyalty. However, the dimensions of "credibility," "attractiveness," and "power" of the brand ambassador show a positive but insignificant effect on brand loyalty. Furthermore, the results highlight the positive and significant influence of purchasing decisions on customer satisfaction, and customer satisfaction, in turn, has a positive and significant impact on brand loyalty.

Résumé :

This study is focused on 'Private Message Service', a monthly subscription service that allows users to receive and reply to messages sent by artists. This study extracted the motivation for using private message service(pseudo feeling of love, entertainment and rest, friendliness, star identification, information seeking, idol support, and reference group conformance desire) and examined how the motivation for using private message service affects satisfaction and loyalty. This study conducted a survey of 354 Chinese female K-Pop fans who had experiences using the private message service. It was found that entertainment and rest, friendliness, star identification, and information seeking motivation have positive effects on satisfaction, while psuedo feeling of love was found to have negative effects on satisfaction. Among the motivational factors for using private message service, entertainment and rest, friendliness, star identification, and information seeking motivation was found to have positive effects on loyalty. And satisfaction was found to have positive effects on loyalty. In addition, there is a complete mediating effect of satisfaction between entertainment and rest, friendliness, star identification, information-seeking motivation, respectively with loyalty. It is hoped that findings of this study would contribute to enhancing the quality of the private message services.

Résumé :

Now-a-days, the research is more towards the entertainment like music, songs, movies, etc. There are many existing works that suggest good songs, movies to people depending on their mood, nature and time that has been savior for the society during the days of lockdown. The existing algorithms used in the literature for basic clustering are K-means, TSNE (T- distributed Stochastic Neighborhood Embedding), PCA (Principal Component Analysis).In this paper, the music dataset considered, consists of songs with attributes as song name, genres, artists, mode, tempo, valence, year, liveness, loudness, popularity, acousticness, danceability, duration, energy, explicit, instrumentalness, key. The important feature is extracted from the other features with the support of literature survey i.e., number of music listeners, types of the songs and type of the music. Later, the dataset is divided into clusters using traditional technique that is k-means based on genre, an important attribute which is selected from the above attributes. The different classifier models like Random Forest, Extra Trees, LightGBM, XGBoost, CatBoost classifier are applied on the clustered dataset and the results have been evaluated on each individual algorithm. Thus the paper recommends not only the group of relevant songs but also suggests the best accurate classification algorithm that can be used for any mentioned musical dataset. The paper also compares all the said ensemble algorithms by calculating the precision, recall, f1-score and support. The accuracy is also calculated for all said ensemble algorithms and based on the accuracy the best suitable algorithm is suggested.

Résumé :

В наследии русских реалистов второй половины XIX в. существует большая группа произведений на евангельский сюжет, решенных по законам станковой картины, в принципах исторического жанра и предназначавшихся для светских выставок. Уникальность этого явления заключается в том, что художники, в отличие от предыдущего времени, создавали их не только по заказу, но и из внутренней потребности, по личной инициативе. Это произведения Г. Ге, В. Г. Перова, И. Н. Крамского, В. И. Сурикова, И. Е. Репина, В. Д. Поленова, В. Е. Маковского, Г. Г. Мясоедова, К. А. Савицкого и, конечно же, В. В. Верещагина. In the heritage of Russian realists of the second half of the XIX century there is a large group of works on an evangelical plot, solved according to the laws of easel painting, in the principles of historical genre and intended for secular exhibitions. The uniqueness of this phenomenon lies in the fact that artists, in contrast to the previous time, created them not only by order, but also from inner need, on personal initiative. This is the work of N. G. Ge, V. G. Perova, N. Kramskoy, V. I. Surikov, I. E. Repin, V. D. Polenova, V. E. Makovsky, G. G. Myasoedova, K. A. Savitsky and, of course, V. V. Vereshchagin.

Résumé :

The article aims to characterize a topical issue through poetics: the Second World War from the perspective of J. Iwaszkiewicz’s individual perception from September 2, 1939, when the Luftwaffe began to bomb Warsaw until the moment of its liberation on January 18, 1945. It is noted that the writer recorded on the pages of his diary not only his psychological state but also that of other people. Particular attention is paid to the first entry of August 12, 1939, where the breakdown of the peaceful life was recorded, during which the writer had been immersed in the problems of art, intending to create a free-form work, a kind of ANNABEL, where the images of the composer Karol Szymanowski, the poets J. Tuwim and S. Witkiewicz would have appeared. The article focuses on the entry of August 28, 1939, which tells about the writer’s deep love for Ukraine and his nostalgic memories of it. The study emphasizes the historical value of almost daily records dedicated to mobilization, dated August 24 and 31, and those testimonies contained in the diary entries from September 4, 5 and 6, which describe the terrible pictures of people fleeing from Podkowa and the state of the road to it, destroyed by bombing. The entry about a terrible entrance to Warsaw, dated September 7, and that with a group portrait of crowds on the roads, dated September 8, are considered from the point of view of artistic skill. The article studies the poetics of tragic scenes of Warsaw residents’ escape and analyzes the entries depicting the underground cultural life of the capital, the secret academy dedicated to K. Szymanowski’s death anniversary, the series of J. Iwaszkiewicz’s lectures about contemporary Polish poetry, Stawisko, where the writer hid writers, artists and fighters against the invaders, about the Uprising and post-war reconstruction. Attention is also given to the recollection of K. Baczynski and W. Draczynska’s marriage.

The work of the «Glasgow Four» (C. R. Mackintosh, J. G. McNair, the Macdonald sisters) in the field of linear direction posters and the works of other authors were considered. Features of linear organization and individual floreal elements in the posters of German-Austrian Secession artists (F. von Stuck, L. von Hoffmann, P. Behrens, G. Klimt, K. Moser, J. Olbrich and others) were identified on the occasion of various level exhibitions in Munich, Berlin, Vienna in the 1890s. The parameters of the formation of the national and romantic trend in the exhibition poster of Polish artists F. Wygzywalski, Y. Mehoffer, J. Bukowski, and T. Aksentowicz were determined. Visualization techniques were analyzed, taking into account the specifics of the poster and general stylistic trends in the art of those years. Considerable attention was paid to highlighting the regional features of poster design in the specified countries, as well as the features of the authors’ individual style within these regional models. Conclusions. In the general cultural and historical context of the time, the exhibition poster was an important component of the formation of national trends in the artistic style of the time, primarily floreal, linear, national-romantic. Reflecting the stylistic guidelines of the time, the exhibition poster, aimed at a wide audience, contributed to the formation of a holistic artistic vision as a manifestation of the cultural and artistic guidelines of the specified period.

Résumé :

Statement of the problem. The article deals with the spiritual and choral works of the composers of the first third of the 20th century on the examples of the liturgical and paraliturgical choral works of K. Stetsenko and O. Koshyts, representatives of the “new school”. (Kozarenko, 2001: 153) of Ukrainian sacred music of the first quarter of the 20th century. Recent research and publications testify to the relevance of the proposed topic. The collection «Olexander Koshyts and time» (Scientific Herald of the UNTAM, 2007, vol. 57) contains scientific articles devoted to various aspects of the creative activity of O. Koshyts. The studies by N. Kalutska (2001) and N. Suprun-Yaremko (2014) are devoted to his composer style. L. Parkhomenko’s monograph (2009) continues to be one of the fundamental works dedicated to K. Stetsenko. O. Zasadna and O. Chersak (2021) examines the process of Ukrainization of liturgical music during the period of national revival (the first third of the 20th century). A. Pater’s dissertation (2021) presents the creative activity of modern professional choirs at Ukraine in the context of the revival of spiritual music. Objectives, methods, and novelty of the research. The purpose of the study is to reveal the genre-stylistic and performing principles of the selected spiritual compositions: the kontakion «Zi Sviatymy Upokoi» («With the Saints Give Rest») from K. Stetsenko’s «Panakhyda»(«Requiem») and the arrangement of the folk psalm «Oi Khto, Khto Mykolaia liubyt» («Oh, Who, Who Loves Nicholas») by O. Koshyts. The scientific novelty of the study is related to highlighting the fundamental qualities of spiritual choral composer work by K. Stetsenko and O. Koshyts in terms of performance interpretation and the continuity of the tradition of Ukrainian spiritual singing in the genre and stylistic dimension. The historical-cultural, genre, stylistic, structural-functional, interpretative, semantic, and systemic methods are used in the study. Results and conclusion. ● The foundation of K. Stetsenko’s and O. Koshyts’s composer work is the involvement of genres of liturgical and paraliturgical heritage (in the considered cases – memorial services, folk psalms) and the principle of psalmody; elements of folk song style and stylization of folklore images (lullaby in “With the Saints Give Rest”, sound image from the Kobzar and lirnyk tradition – imitation of the sound of the wheel lyre in “Oh, who, who loves Nicholas”). ● The choral work of both artists is characterized by certain common musical and stylistic features: a tendency towards multi-layered texture and expansion of the general range of sound in climaxes; involving the principles of antiphonal singing inherited from the established tradition of Ukrainian choral music; interpretation of the choir as an orchestra of voices; repetition of some syllables of the phrase in the chorus, which is characteristic of the tradition of group folk singing; major-minor variability. ● The examples of modern interpretations of the compositions testify to the high quality of rendition of the spiritual compositions, which was achieved through remarkable plasticity of voice management, experimental choirmaster work on the timbre combinations, microdynamics, etc. ● In our time, the performance interpretations of the spiritual works of the composers of the first third of the 20th century by the best choirs of Ukraine is the evidence of the revival and continuity of the domestic spiritual tradition on a new stage of its understanding.. Masterpieces of spiritual choral heritage, updated after a long time of prohibition in a new quality, prove their enduring value in the 21st century.

Résumé :

Purpose This study aims to propose a new genetic algorithm for solving supply chain scheduling and routing problem in a multi-site manufacturing system. The main research question is: How is the production and transportation scheduled in a multi-site manufacturer? Also the sub-questions are: How is the order assigned to the suppliers? What is the production sequence of the assigned orders to a supplier? How is the order assignment to the vehicles? What are the vehicles routes to convey the orders from the suppliers to the manufacturing centers? The authors’ contributions in this paper are: integration of production scheduling and vehicle routing in multi-site manufacturing supply chain and proposing a new genetic algorithm inspired from the role model concept in sociology. Design/methodology/approach Considering shared transportation system in production scheduling of a multi-site manufacturer is investigated in this paper. Initially, a mathematical model for the problem is presented. Afterwards, a new genetic algorithm based on the reference group concept in sociology, named Reference Group Genetic Algorithm (RGGA) is introduced for solving the problem. The comparison between RGGA and a developed algorithm of literature closest problem, demonstrates a better performance of RGGA. This comparison is drawn based on many test problems. Moreover, the superiority of RGGA is certificated by comparing it to the optimum solution in the small size problems. Finally, the authors use real data collected from a drug manufacturer in Iran to test the performance of the algorithm. The results show the better performance of RGGA in comparison with obtained outputs from the real case. Findings The authors presented the mathematical model of the problem and introduced a new genetic algorithm based on the “reference group” concept in sociology. Robert K. Merton is a sociologist who presented the concept of reference groups in society. He believed that some people in each society such as heroes or entertainment artists affect other people. The proposed algorithm uses the reference group concept to the genetic algorithm, namely, RGGA. The comparison of the proposed algorithm with DGA and the optimum solution shows the superiority of RGGA. Finally, the authors implement the algorithm in a real case of drug manufacturing and the results show that the authors’ algorithm gives better outputs than obtained outputs from the real case. Originality/value One of the major objectives of supply chains is to create a competitive advantage for the final product. This intension is only achieved when each and every element of the supply chain considers customers’ needs in every function of theirs. This paper studies scheduling in the supply chain of a multi-site manufacturing system. It is assumed that some suppliers produce raw material or initial parts and convey them by a fleet of vehicles to a multi-site manufacturer.

Résumé :

Adiponitrile, C6H8N2, is a key intermediate in the synthesis of the polyamide Nylon 66 and is produced industrially on a large scale. We have determined the crystal and molecular structure of adiponitrile by single-crystal X-ray analysis at 100 K, a suitable crystal (m.p. 275 K) having been grown from the melt at low temperature. The compound crystallizes in the monoclinic space group P21/c with Z = 2. In the crystal structure, the molecule adopts an exact C i-symmetric gauche–anti–gauche conformation of the C—C—C—C skeleton about an inversion centre. The molecules are densely packed, with short intermolecular contacts between the α-H and nitrile N atoms.

Résumé :

Functionalization of metal-organic frameworks resulting in efficient CO2 adsorption materials became substantial in preventing the worsening environment upon the emission of CO2. In this study, several room-temperature ionic liquids (RTILs) with an imidazolium-based cation of 1-butyl-3-methylimidazolium [bmim]+ and anions of bis(trifluoromethylsulfonyl)imide [TFSI]−, trifluoromethanesulfonate [OTf]−, hexafluorophosphate [PF6]−, and tetrafluoroborate [BF4]− were incorporated into UiO-66 by wet impregnation method under air. The RTILs/UiO-66 composites were characterized by PXRD, FTIR, TGA, nitrogen physisorption, and CO2 adsorption. Based on the type of anions of imidazolium-based RTILs, the CO2 uptake of RTILs/UiO-66 composites followed the trend: [OTf]− > [TFSI]− > [PF₆]− > [BF₄]− at low temperature (273 K) and pressure (100 kPa). The CO2 uptake of pristine UiO-66 increased approximately 1.5 times upon incorporating [bmim][OTf]. The type of anions of imidazolium-based RTILs influences the CO2 adsorption performance of RTILs/UiO-66 composites in which anions containing fluoroalkyl group ([OTf]−, [TFSI]−) exhibited a higher CO2 uptake compared to inorganic fluorinated anions ([BF4]−, [PF6]−). Hence, the incorporation of hydrophobic imidazolium-based RTILs showed a potential to enhance the performance of UiO-66 for CO2 adsorption application.

Résumé :

The level of sensitivity of Klebsiella pneumoniae strains isolated from children of the first half of life with functional gastrointestinal disorders (FGID) to commercial bacteriophage preparations was assessed. The material was the feces of 67 children of the first half of life with FGID who are breastfed. Culture of K. pneumoniae isolated from faeces of children, amounted to two comparison groups, depending on the age of the patients. The first group included 43 K. pneumoniae strains isolated from the colon of children aged from birth to three months, in the second group - 24 strains, from children aged three to six months. The composition of the colon microbiota was studied using standard methods, and the results were evaluated in accordance with Industry Standard 91500.11.0004-2003. Identification of K. pneumoniae was performed by bacteriological methods. Determination of the level of lytic activity of K. pneumoniae, Klebsiella polyvalent and sextaphage bacteriophages to K. pneumoniae strains was conducted by the drip method (spot-test) according to clinical recommendations. It is shown that the formation of FGID symptoms in children correlates with age - the frequency of regurgitation decreased in children up to six months (from 23.3% to 4.2%) against the background of the formation of a symptom complex associated with defecation disorder. Bacteriological analysis showed that in General, phages show a low level of lytic activity, sensitivity to them Klebsiella also correlated with age and was higher in children of three to six months. Thus, in the first comparison group, the absence of Klebsiella lysis in relation to the Klebsiella pneumoniae bacteriophage was registered three times more often (30.2%, p<0.05) and twice less often (30.2%, p<0.05), the low level of lysis of K. pneumoniae strains to the Klebsiella polyvalent phage compared to the second group. The sensitivity of K. pneumoniae strains to sextaphage was comparable in comparison groups and varied from 2 to 10%. Thus, among the studied K. pneumoniae observed a low level of sensitivity to specific drugs - bacteriophage Klebsiella pneumoniae, Klebsiella polyvalent and sextaphage. This fact reflects the insufficient activity of phages and predicts low effectiveness of empirical phage therapy without elimination from the intestinal biocenosis of K. pneumoniae in children with FGID who are breastfed.

Résumé :

The aim of this study was to evaluate whether production costs can be reduced and whether the profitability of organic chicken fattening can be increased by selecting the appropriate genotypes. Rhode Island Red (K-11) and Sussex (S-66) conservative chicken genotypes, as well as modern chicken genotypes such as slow-growing Hubbard JA 957 hybrids and fast-growing Ross 308 hybrids, were selected for the study. One hundred and sixty chickens were used in the experiment (forty birds per group). The birds were fed commercial organic complete feed up to 52 days of age and organic farm-made feed (to reduce costs) between 53 and 81 days of age. Population distribution was determined using the Kolmogorov–Smirnov test. The results were analyzed statistically using one-way analysis of variance (ANOVA) with multiple comparisons and the post hoc Tukey test at a significance level of p < 0.05. The 81-day fattening period (the minimum recommended period in organic farming) led to considerable weight deficits in Rhode Island Red and S-66 chickens and excessive slaughter/trade weights in Hubbard JA 957 and Ross 308 chickens. The feed conversion ratio was high in Rhode Island Red (K-11) and Sussex (S-66) chickens at 4.19 and 4.50, respectively, and much lower in Hubbard JA 957 and Ross 308 chickens at 2.79 and 2.53, respectively. The choice of chicken genotypes had a major impact on the profitability of organic farming, and the total costs of feed and other ingredients per kg of body weight were determined at EUR 3.83 for Rhode Island Red (K-11), EUR 3.90 for Sussex (S-66), EUR 6.57 for Hubbard JA 957, and EUR 6.62 for Ross 308 genotypes. The profitability of organic farming can be increased by selecting modern, meat-type, slow-growing chicken genotypes.

Résumé :

Background: Fear of operation, injections, physicians and peculiar operation theatre environment where children are separated from their parents prior to anesthesia invariably produce traumatic experiences in tender mind of young children. Midazolam and Ketamine are useful for oral premedication in children to allay anxiety, allow separation from parents and to ensure smooth induction.Methodology: It was a prospective, randomized, double-blinded and comparative study conducted in 80 children of ASA I and II aged 1-6years undergoing elective ophthalmological procedures under general anesthesia. Children were randomized and divided into two groups, K received 4mg/kg of Ketamine and MK received 0.2mg/kg of Midazolam+2mg/kg of Ketamine peroral. Sedation level, ease of parental separation and ease of mask acceptance were evaluated within 20-30 minutes on a 4-point scale. The time to achieve modified Aldrete score of ≥9 was also noted.Results: Two groups were identical regarding age, sex, weight and ASA status. In sedation score, 31(77.5%) children in group K and 35(87.5%) children in group MK were awake, calm and quite (score3)(p=0.50). In parental separation score, 34(85%) children in group MK and 25(62.5%) children in group K have good separation, awake and calm (score2) (p=0.04). In mask acceptance score, 34(85%) children in group MK and 17(42.5%) children in group K were calm, awake, cooperative, accepting Mask (score1)(p=0.001). Time of recovery in group K was 17.92}6.50min whereas in group MK was 17.80}4.059min(p=0.91).Conclusion: Ketamine 4mg/kg and combination of Midazolam 0.2mg/kg with Ketamine 2mg/kg are equally effective but low dose combination is safe and superior.

Résumé :

Character of modern tennis game in the last decade has become significantly more dynamic, fast and powerful, which brings high strain to joint and muscular system. The aim of this research was to establish strength level of external and internal shoulder rotators, and to compare the competitive tennis players group of boys (TEN, n=10, aged 12-14 years) and boys who did not perform any sport activity at competitive level (CS, n=10, aged 12-14 years) as well as to assess lateral differences in both groups. Using isokinetic dynamometry method (Humac Norm CSMI Stoughton, MA, USA), we tested strength level of external and internal shoulder rotators (180°/s, 300°/s). The TEN and CS group are comparable from the aspects of age, body height and body weight. Comparison of isokinetic strength values in TEN and CS groups proved significantly higher strength level of external and internal rotators in both (dominant and non-dominant) extremities for the TEN group. The lateral difference assessment proved the insignificant difference in external and significant difference in internal rotators in the TEN group, and the insignificant difference in both the external and internal rotators in the CS group. A lower strength level was found in the internal rotators in comparison with the external rotators in both groups (for both the dominant and non-dominant extremity), whereas in the TEN group lower differences between the external and internal rotators of the dominant extremity were proved. Although researches on adult highly skilled tennis players refer to a higher strength level of the upper extremity internal rotators, this fact has not been pronounced in the TEN group. An ideal external/internal rotators̕ ratio in adult players is considered within the interval of 66-75%. Significantly higher values obtained in the TEN group might be attributed to lower age and also lower performance level. It can be said that the level of isokinetic strength in the TEN the group is significantly higher than in the CS group, due to the influence of long-term game and training load.

Résumé :

Physical education curricula in Polish schools should include more tasks to increase physical activity. The Tabata Training Program can help regulate body weight and induce changes in body fat and physical fitness. This study aimed to determine the effects of a 10-week PE curriculum supplemented by a Tabata Training Program on health-related fitness in 16-year-old secondary school students. The study examined 187 students (66 boys and 121 girls) assigned to either a Tabata Training Program intervention or control group. The intervention lasted 14 minutes during one physical education lesson per week. Pre- and post-intervention, anthropometric measurements were taken, and each participant performed physical fitness tests to evaluate muscular strength, flexibility, speed/agility, and cardiovascular efficiency. Boys of the intervention group significantly reduced body fat (by 1.77%, p<.05) and increased cardiovascular efficiency (the physical efficiency index was higher by 3.61 points, p<.05). Girls increased cardiovascular efficiency only (the physical efficiency index increased by 5 points, p<.001). However, slight changes in motor parameters were observed in all the participants. The Tabata Training Program demonstrated partial effectiveness but should be individualized and sex differences should be considered.

Résumé :

В хорошо представленном в научном дискурсе творчестве уральского художника Миши Шаевича Брусиловского (1931–2016) есть работа, незаслуженно обойденная как историками искусства, так и художественной критикой. Это «Групповой портрет бригады кузнецов УЗТМ» 1977 года. Авторы статьи описывают опыт актуализации полотна для экспозиционных, воспитательных, фандрайзинговых (проектных) целей и трудности их достижения. Фиксируется противоречие — живописное полотно маститого автора явно заслуживает более активного изучения и экспонирования, но эти процессы затруднены состоянием картины (экспертами оценивается как предаварийное) и правами обладания (корпоративный музей). Использован историко-описательный и монографический методы, приводятся результаты социологического исследования зрительского опыта взаимодействия с картиной на «Ночи музеев» в 2018 году. Впервые опубликована история возвращения картины в музейную среду, фотография из мастерской М.Ш. Брусиловского, где позируют прототипы героев полотна, описана методика актуализации наследия «индустриального искусства» советского периода на примере «Группового портрета бригады кузнецов УЗТМ»: сбор исторических сведений, воспоминаний, проект учащихся школы искусств, партисипаторное проектирование экспозиции с участием студентов вуза, публикации в СМИ, фандрайзинг. In the work of the Ural artist Misha Shayevich Brusilovsky (1931–2016), well represented in scientific discourse, there is a painting undeservedly bypassed by art historians and art criticism. This is the “Group portrait of the UZTM blacksmith team” (1977; UZTM — Ural Heavy Machinery Plant). The authors describe the experience of updating tables for exposition, educational, fundraising (project) purposes and demand their achievements. A contradiction is fixed — the painting by the venerable author, apparently, is more actively studied and exhibited, but these processes are hampered by the state of the painting (expert assessment as pre-accident) and ownership rights (corporate museum). Here, historical-descriptive and monographic methods are used, when using the results of a historical and sociological study of the viewer's experience of impressions with a painting at the Night of Museums in 2018. The history of the return of paintings to the museum environment was published for the first time, as well as the photograph from the workshop of M. Brusilovsky, where paintings are posed (foreman A. Kordukov, blacksmiths B. Shulepov, K. Le, A. Moskvin, V. Venchinov, I. Bersenev, V. Erer), the methodology for updating the heritage of “industrial art” of the Soviet period of manifestation is described, namely, such stages as collection of special identified memories, a project of students of art schools, participatory design of products with the involvement of university students, in the media, fundraising. Fundraising in the objects of restoration of paintings and its exposure to the general public can be based on various arguments — attention and interest in the time of creation of the canvas as an example of “industrial painting” of the Soviet period, increasing the motivation of the copyright holder (big business), etc. At the moment, restoration work of the painting continues.

Hematoma formation has persisted as the most common complication in rhytidectomy. The objective of this study is to determine the efficacy and safety of Artiss (Baxter) for use in rhytidectomies. In addition, we determine the use of fibrin tissue sealants by facial plastic surgeons. In this retrospective chart review, 120 patients in a single private practice were identified who underwent a rhytidectomy from August 2013 to January 2015 by a single facial plastic surgeon. The last 60 rhytidectomies performed with Tisseel (Baxter) were compared with the first 60 rhytidectomies performed with Artiss.All perioperative or postoperative complications were identified and recorded, focusing on the incidence of hematoma. In addition, a six-question survey was created and sent to all members of the American Academy of Facial Plastic and Reconstructive Surgery. Results of the survey were recorded and analyzed for trends or patterns in the data. In total, 120 patients were assessed. In the Tisseel group, two complications of fluid collection requiring needle aspiration were recorded. No other complications were found. In the Artiss group, 10 complications were recorded, including 9 fluid collections requiring needle aspiration and 1 hematoma. In total, 179 members of the American Academy of Facial Plastic and Reconstructive Surgery completed the six-question survey. Of all respondents, 61 (34%) use tissue sealants for rhytidectomies, whereas 118 (66%) do not. Artiss is efficacious and safe for use in rhytidectomies. Its use obviates the need for surgical drains, and complications are minimal and similar in rate to the use of Tisseel.

Résumé :

K(+)-deficient rats and control rats were infused for 14 days with vehicle: acetic acid (AcA) or recombinant human insulin-like growth factor-I (IGF-I, 240 micrograms/day) by osmotic minipumps. IGF-I treatment of K(+)-deficient rats did not result in overall growth of carcass or muscles but in marked selective growth of adrenals (+42%) and spleen (+66%). In control rats, IGF-I induced increased body and muscle weight, tibia length, and thymus weight. K+ deficiency was associated with reduced serum IGF-I but unchanged thyroid status. IGF-I treatment of the K(+)-deficient rats restored serum IGF-I and decreased total 3,5,3'-triiodothyronine. In AcA-treated K(+)-deficient rats [3H]ouabain binding site concentration decreased by 63 and 43% in soleus and extensor digitorum longus (EDL) muscle, respectively, compared with the AcA-treated controls. IGF-I had no effect on the [3H]ouabain binding site concentration in the control group, but in K(+)-deficient rats a significant lowering of 26% was observed in EDL. K+ deficiency causes relative organ-specific resistance to the growth-promoting effects of IGF-I, comparable to the effects seen in protein-restricted rats. Reduced circulating IGF-I is not the only cause of the downregulation of Na(+)-K+ pumps in K+ deficiency, and IGF-I treatment of control animals in vivo has no stimulatory effect on the synthesis of Na(+)-K+ pumps.

Résumé :

The aim of this study was to investigate the levels of motivation associated with participation in floorball (indoor hockey) and spinning, and how levels of motivation predicted continuation. A sample of 66 middleaged women participated in a 12-week intervention of either floorball or spinning. They filled out the Sport Motivation Scale in week 2 and week 11 of the intervention, and data on their continuation six and 12 months after the intervention was also collected. A repeated measures MANOVA showed that participants in the floorball group had higher levels of intrinsic and self-determined extrinsic motivation for the activity during the intervention period, suggesting that floorball is a more motivating activity. In addition, extrinsic motivation the introjected regulation increased in both groups during the intervention period. Intrinsic motivation, as well as extrinsic motivation introjected regulation, predicted participants’ continuation six and 12 months after the intervention, suggesting that motivation as viewed in a Self-Determination Theory perspective is important for continuation.

Parker, James C., and Claire L. Ivey.Isoproterenol attenuates high vascular pressure-induced permeability increases in isolated rat lungs. J. Appl. Physiol. 83(6): 1962–1967, 1997.—To separate the contributions of cellular and basement membrane components of the alveolar capillary barrier to the increased microvascular permeability induced by high pulmonary venous pressures (Ppv), we subjected isolated rat lungs to increases in Ppv, which increased capillary filtration coefficient ( K fc) without significant hemorrhage (31 cmH2O) and with obvious extravasation of red blood cells (43 cmH2O). Isoproterenol (20 μM) was infused in one group (Iso) to identify a reversible cellular component of injury, and residual blood volumes were measured to assess extravasation of red blood cells through ruptured basement membranes. In untreated lungs (High Ppv group), K fc increased 6.2 ± 1.3 and 38.3 ± 15.2 times baseline during the 31 and 43 cmH2O Ppv states. In Iso lungs, K fc was 36.2% ( P < 0.05) and 64.3% of that in the High Ppv group at these Ppv states. Residual blood volumes calculated from tissue hemoglobin contents were significantly increased by 53–66% in the high Ppv groups, compared with low vascular pressure controls, but there was no significant difference between High Ppv and Iso groups. Thus isoproterenol significantly attenuated vascular pressure-induced K fc increases at moderate Ppv, possibly because of an endothelial effect, but it did not affect red cell extravasation at higher vascular pressures.

Résumé :

Introduction The study of Klebsiella quasipneumoniae, Klebsiella variicola, and AmpC production in extended-spectrum β-lactamase (ESBL)-producing Klebsiella in Japan is limited, and existing data are insufficient. This study aims to characterize Klebsiella species, determine AmpC production rates, and analyze antimicrobial resistance patterns in ESBL-producing Klebsiella isolates in Japan. Methods A total of 139 clinical isolates of ESBL-producing Klebsiella were collected in Japan, along with their corresponding antimicrobial susceptibility profiles. The isolates were identified using a web-based tool. ESBL genes within the isolates were identified using multiplex PCR. Screening for AmpC-producing isolates was performed using cefoxitin disks, followed by multiplex PCR to detect the presence of AmpC genes. Antimicrobial resistance patterns were analyzed across the predominant ESBL genotypes. Results The web-based tool identified 135 isolates (97.1%) as Klebsiella pneumoniae and 4 (2.9%) as K. quasipneumoniae subsp. similipneumoniae, with no instances of K. variicola detected. Among K. pneumoniae, the CTX-M-1 group emerged as the predominant genotype (83/135, 61.5%), followed by K. quasipneumoniae subsp. similipneumoniae (3/4, 75.0%). The CTX-M-9 group was the second most prevalent genotype in K. pneumoniae (45/135, 33.3%). The high resistance rates were observed for quinolones (ranging from 46.7% to 63.0%) and trimethoprim/sulfamethoxazole (78.5%). The CTX-M-1 group exhibited higher resistance to ciprofloxacin (66/83, 79.5%) compared to the CTX-M-9 group (18/45, 40.0%), a trend also observed for levofloxacin and trimethoprim/sulfamethoxazole. Among the 16 isolates that tested positive during AmpC screening, only one K. pneumoniae isolates (0.7%) were confirmed to carry the AmpC gene. Conclusion Klebsiella pneumoniae with the CTX-M-1 group is the most common ESBL-producing Klebsiella in Japan and showed a low proportion of AmpC production. These isolates are resistant to quinolones and trimethoprim/sulfamethoxazole, highlighting the challenge of managing this pathogen. The findings underscore the importance of broader research and continuous monitoring to address the resistance patterns of ESBL-producing Klebsiella.

In all the polymorphs the azobenzene group is in the more stable trans conformation. The polymorphism arises from the high conformational flexibility of the bridges, which are arranged differently and are highly disordered in the two monoclinic forms (1) and (2a). Form (2a) presents a phase transition near 268 (2) K, leading to a triclinic form (2b), differing from the high-temperature form by some ordering of the chains and a subsequent reduction in crystallographic site multiplicity. The evolution of the cell parameters and peak width with temperature has been investigated down to 173 (2) K. Adiabatic calorimetry measurements indicate a smooth transition centered at 265.0 (1) K, with a heat capacity jump of 60 mJ g−1 K−1, suggesting a second-order nature for the transition.

Résumé :

ObjectiveExploration of healthcare utilisation patterns in the final life year to assess palliative care potential.MethodsRetrospective cluster analyses (k-means) of anonymised healthcare expenditure (HCE) trajectories, derived from health insurance claims of a representative sample of Swiss decedents who died between 2008 and 2010 (2 age classes: 4818 <66 years, 22 691 elderly).Results3 (<66 years) and 5 (elderly) trajectory groups were identified, whose shapes were dominated by HCE from inpatient care in hospitals and at nursing homes. In each age class, the most expensive group (average cumulative HCE for <66 years: SFr 84 295; elderly: SFr 84 941) also had the largest abundance of cancers (<66 years: 55%; elderly: 32%) and showed signs of continued treatment intensification until shortly before death. Although sizes of these high-cost groups were comparatively small (26% in younger; 6% in elderly), they contributed substantially to the end-of-life HCE in each age class (62% and 18%, respectively).As age increased, these potential target groups for palliative care gained in share among <66-year olds (from 9% in children to 28% in 60–65-year olds), but decreased from 17% (66–70-year olds) to 1% (>90-year olds) among elderly.ConclusionsCost trajectory clustering is well suited for first-pass population screenings of groups that warrant closer inspection to improve end-of-life healthcare allocation. The Swiss data suggest that many decedents undergo intensive medical treatment until shortly before death. Investigations into the clinical circumstances and motives of patients and physicians may help to guide palliative care.

Résumé :

BackgroundVascular calcification, a risk factor for cardiovascular disease, is common among patients with CKD and is an independent contributor to increased vascular stiffness and vascular risk in this patient group. Vitamin K is a cofactor for proteins involved in prevention of vascular calcification. Whether or not vitamin K supplementation could improve arterial stiffness in patients with CKD is unknown.MethodsTo determine if vitamin K supplementation might improve arterial stiffness in patients in CKD, we conducted a parallel-group, double-blind, randomized trial in participants aged 18 or older with CKD stage 3b or 4 (eGFR 15–45 ml/min per 1.73 m2). We randomly assigned participants to receive 400 μg oral vitamin K2 or matching placebo once daily for a year. The primary outcome was the adjusted between-group difference in carotid-femoral pulse wave velocity at 12 months. Secondary outcomes included augmentation index, abdominal aortic calcification, BP, physical function, and blood markers of mineral metabolism and vascular health. We also updated a recently published meta-analysis of trials to include the findings of this study.ResultsWe included 159 randomized participants in the modified intention-to-treat analysis, with 80 allocated to receive vitamin K and 79 to receive placebo. Mean age was 66 years, 62 (39%) were female, and 87 (55%) had CKD stage 4. We found no differences in pulse wave velocity at 12 months, augmentation index at 12 months, BP, B-type natriuretic peptide, or physical function. The updated meta-analysis showed no effect of vitamin K supplementation on vascular stiffness or vascular calcification measures.ConclusionsVitamin K2 supplementation did not improve vascular stiffness or other measures of vascular health in this trial involving individuals with CKD.Clinical Trial registry name and registration numberVitamin K therapy to improve vascular health in patients with chronic kidney disease, ISRCTN21444964 (www.isrctn.com)

Résumé :

Abstract Introduction This study examines the difference in sleep hygiene status according to age and sex and the relationship between sleep hygiene and insomnia in the non-clinical Korean population using the Sleep Hygiene Practice Scale in Korean (SHPS-K), validated through this study. Methods We recruited non-clinical adults (Aged 18-65) without a history of neurologic, psychiatric, or medical disorders and diagnosed sleep disorders. An online survey was done using SHPS-K, the Pittsburgh Sleep Quality Index (PSQI-K), Insomnia Severity Index (ISI-K), and Epworth Sleepiness Scale (KESS). The first survey enrolled 484 participants (242 women, mean age of 43.8 years), among whom 322 completed the second survey. SHPS-K was compared between each age group, sex, and group with or without insomnia symptoms (ISIS-K 15). Using receiver operating characteristic analysis in different age groups, we also determined the cutoff values that could identify poor sleepers with insomnia symptoms (PSQI-K > 5 and ISI-K 15). Results The average total SHPS-K score was 71.2, with no sex difference. Mean ISI-K, PSQI, and ESS were not different between sex and age groups. The older participants had lower SHPS-K than the younger groups, with a significant trend for ages ( =-3.01, p< 0.001). This trend was significant in both men and women. Men had poorer eating and drinking behaviors among the four domains, and women had poorer sleep scheduling and timing behaviors. Young adults with insomnia symptoms showed the highest SHPS-K than other age groups with insomnia (p < 0.001). A cutoff value of 76, 74, and 66 identified poor sleepers with insomnia (area under the curve = 0.818, 0.837, 0.849) in young, middle-aged, and older adults, respectively. Conclusion This study showed that sleep-disturbing behaviors were different between age groups and sex. The group with insomnia symptoms showed worse sleep hygiene practices. Furthermore, young adults had significantly worse sleep hygiene than middle-aged or older adults. Sleep hygiene education could contribute differentially to improving sleep quality in non-clinical populations. Support (if any)

Résumé :

This study was aimed at investigating the diagnostic value of MRI based on K-space data reconstruction algorithm for anterior cruciate ligament (ACL) injury of knee joint and the influencing factors of ligament injury. 96 patients with ACL injury of knee joint were selected, and they were randomly divided into two groups: group A (arthroscopy) and group B (MRI examination), and another 96 healthy volunteers in the same period were selected as the control group. The test results of each indicator were compared. The results showed that the signal-to-noise ratio (SNR) of SMASH algorithm was higher than that of sum of squares (SOS) algorithm. In group A, there were 66 positive and 30 negative tests, and in group B, there were 56 positive and 40 negative tests ( P < 0.05 ). The intercondylar fossa width, the intercondylar fossa width index, and the ratio of tibial intercondylar eminence width to intercondylar fossa width in group B were lower than those in the control group ( P < 0.05 ). Compared with the traditional SOS algorithm, SMASH algorithm can improve the image quality, reduce the impact of damage data on the final synthesis image, and improve the image SNR. In clinical work, the ratio of the width of tibial intercondylar eminence to the width of femoral intercondylar fossa can be measured by imaging data to evaluate the matching between tibial intercondylar eminence and femoral intercondylar fossa, so as to evaluate the risk of ACL rupture.

Résumé :

556 Background: K-ras mutation is a negative predictor of clinical benefit (CB) from anti-EGFR treatment in mCRC. Bevacizumab combined with chemotherapy prolongs both PFS and OS in first-line treatment of mCRC. Previously data suggested that this results are independent of K-ras status. We conducted a study to investigate the CB of Bevacizumab in treatment of mCRC according to K-ras status and to evaluate timing of response to treatment trough the correlation between tumor markers values and clinical responses. Finally we evaluated CB in patients affected by mCRC with only hepatic metastases vs patients with multiple metastasis sites. Methods: 82 patients were enrolled and underwent first-line chemotherapy with Folfiri or FolFoX and bevacizumab. Tissue samples were analyzed for DNA sequencing in order to identify K-ras mutations in codons 12 and 13. Before therapy all patients were investigated with CT scan and with a blood sample to define tumor markers values; a new evaluation of tumor markers after 2 months of chemotherapy was performed and a CT scan after 3 months. Results: An overall objective response rate (RR) of 40% and a CB of 79% were obtained, with a correlation between tumor markers values and clinical response of 89%. 49% of population presented only hepatic metastases while other 51% showed multiple metastatic sites. RR in exclusive hepatic metastatic group was 45% vs 33% multiple metastatic sites group, CB was 90% vs 66% respectively. No grade 3 or 4 bevacizumab associated toxicity was showed in patients. K-ras mutations were investigated in 75 of 82 patients. 49 patients were wild-type (wt 65%) while 26 patients were mutated (mut 35%). RR in wt group was 45% vs 35% in mut group, while CB was 82% vs 81% respectively. Correlation between tumor markers values and clinical response was 90% in wt group vs 93% in mut group. Conclusions: RR in two K-ras groups was different with an advantage in K-ras wt group, but this difference does not observe in CB. Bevacizumab provides significant RR and CB after a short time of treatment and tumor markers values could be an optimal correlative parameters of early clinical response. Bevacizumab provides significant CB in patients with only hepatic metastases vs patients with multiple metastatic sites. No significant financial relationships to disclose.

Résumé :

The aim of the study was to assess the effects that a steps/day programme may have on body mass index (BMI) among primary education students (11.37±0.48 years). A six-week controlled trial with a follow-up was completed with an experimental group (N=66, pedometer + steps/day programme + reinforcement programme in their physical education (PE) marks + weekly follow-up in PE), and a control group (N=76). Omron HJ-152-E2 pedometers were used. Normoweight students complied with programme requirements to a greater extent than their overweight counterparts (72.7 vs 59.1%). The programmed minimum number of 12,000 steps/day for boys and 10,000 for girls was exceeded by 83% of boys and 60% of girls. The differences in the number of steps/day between boys (14,274) and girls (10,626) were significant across all the measured periods (p<.05). The results show that the teenagers who complied with the programme requirements reduced their BMI significantly after the intervention (p<.001) and this reduction persisted for six weeks after the programme (p<.001). In conclusion, the six-week programme of 12,000 steps/day for boys and 10,000 for girls, jointly with a reinforcement programme in their PE marks and weekly follow-up by their PE teacher, reduces BMI significantly in 11-12-year-old schoolchildren. Monitored steps/day programmes in the PE curriculum increase out-of-school physical activity and reduce BMI in 11-12-year-old schoolchildren.

Résumé :

This study aimed to compare tactical behaviour and performance of football players with different on-the-ball skills execution functional technical asymmetry levels and to verify whether functional technical and tactical performance indexes of football players are associated. The sample included 59 football players (14.2 ± 1.5 years of age). FUT-SAT and SAFALL-FOOT were used as instruments for performance analysis. Participants were divided in two groups: higher and lower functional technical asymmetry. Student’s t-test was used to compare the behaviour and tactical performance of the groups, and the Pearson test was used to verify associations between functional technical asymmetry and tactical performance indexes. A significance level of 5% was adopted. The higher functional technical asymmetry group showed less tactical efficiency (t57 = 1.9; p = .05; d = .17) and low performance results in the execution of defensive actions (t57 = 2.1; p = .04; d = .55; t57 = 2.1; p = .04; d = .61) compared to the lower functional technical asymmetry group. No association was found between the functional technical asymmetry and tactical performance indexes (r = -.06; p = .66). It is concluded that the levels of functional technical asymmetry affected the behaviour and tactical performance of players although functional technical asymmetry and tactical performance indexes values are not associated. Future investigations may verify how football players with high and low levels of functional technical asymmetry change their behaviour and tactical performance from different kinds of training.

Résumé :

SummaryLittle study has been performed on the effect of vitamin K intake on the variability of warfarin’s anticoagulant effects over long period of time. We estimated average vitamin K intake in the patients taking warfarin and evaluated its relation with the stability of anticoagulation effect. We estimated average daily vitamin K intake based on a three-day food diary in 66 patients taking warfarin regularly for ≥one year and divided them into three groups of equal number according to vitamin K intake. Stability of anticoagulant effect was compared in these groups using the coefficient of variation (CV) of the prothrombin time expressed in international normalised ratio (INR) and the CV of warfarin doses. Median daily vitamin K intake was 161.3 μg/day (31.3 μg/day – 616.6 μg/day). CVs of both INR and warfarin doses were negatively and independently correlated with dietary vitamin K intake (r=-0.293, p=0.017 and r= –0.350, p=0.004, respectively). CV of INR was significantly different among three groups of vitamin K intake (p<0.05 in ANOVA). High vitamin K intake (>195.7 μg/day) group had lower CV of INR than the low intake (<126.5 μg/day) group (19.2 ± 8.96 % vs. 25.5 ± 8.61 %, p<0.05). CV of warfarin doses was also significantly different among the groups (p<0.05 in Jonckheere-Terpstra test). However, the significance of difference between high and low vitamin intake groups was marginal (p=0.046 in Mann-Whitney test). In conclusion, long-term anticoagulation effect of warfarin is more stable in the patients who take greater than a certain amount of dietary vitamin K.Footnote: The content of this paper was submitted as partial fulfillment of the requirement for the degree of Master of Medical Science (Kim KH) to the Kyungpook National University.

Résumé :

The travelling solvent floating zone (TSFZ) growth of Eu-substituted LSCO (La1.81−xEuxSr0.19CuO4, with nominal x = 0 ÷ 0.4) single crystals was systematically explored for the first time. The substitution of La with Eu considerably decreased the decomposition temperature. Optimal growth parameters were found to be: oxygen pressure 9.0–9.5 bars; Eu-free CuO-poor solvent (66 mol% CuO) with a molar ratio of La2O3:SrCO3:CuO = 4:4.5:16.5 and growth rate 0.6 mm/hour. The obtained single crystals were characterized with optical polarized microscopy, X-ray diffraction and energy-dispersive X-ray spectroscopy analysis. The solubility of Eu in LSCO appeared to be limited to x~0.36–0.38 under the used conditions. The substitution of La3+ with smaller Eu3+ ions led to a structural transition from tetragonal with space group I4/mmm for La1.81Sr0.19CuO4 (x = 0) to orthorhombic with space group Fmmm for La1.81−xSr0.19EuxCuO4 (x = 0.2, 0.3, 0.4), and to a substantial shrinking of the c-axis from 13.2446 Å (x = 0.0) to 13.1257 Å (x = 0.4). Such structural changes were accompanied by a dramatic decrease in the superconducting critical temperature, Tc, from 29.5 K for x = 0 to 13.8 K for 0.2. For x ≥ 0.3, no superconductivity was detected down to 4 K.

Résumé :

From a review of 57 patients with flexion deformity of the fingers (camptodactyly), 21 patients with 38 digits treated operatively had 18% good or excellent results, whereas 14 patients (41 digits) treated conservatively had 66% good or excellent results. Mild deformities responded well to splints and stretching. Moderate deformities treated operatively gained extension but at the loss of finger flexion. Severe deformities had improvement in extension (averaging 19° in operative cases and 27° in conservative), but there was significant loss of flexion in the operative group. Overall, 16 of 21 patients had loss of flexion after operative treatment. Conservative treatment of camptodactyly is recommended for digits with less than 60° lack of extension. Operative treatment should be reserved for failed conservative treatment. Early joint motion post-operatively appears essential and surgical procedures that immobilise the P.I.P. joints should be avoided.

Résumé :

Vitamin D supplementation has been widely promoted to restore 25-hydroxyvitamin D concentrations; however, experimental evidence suggests a nutrient interaction with vitamin K. We assessed the effects of 1200 IU vitamin D3 per day versus placebo for six months on vitamin K status in a randomized, double-blind, placebo-controlled trial with participants aged 60–80 years with depressive symptoms and ≥1 functional limitation for a secondary analysis. Stored baseline and six-month follow-up blood samples were available for 131 participants (n = 65 placebo vs. n = 66 vitamin D supplementation). We measured dephosphorylated uncarboxylated matrix gla protein (MGP) (dp-ucMGP) concentrations—a marker of vitamin K deficiency. Mean age was 68 years, and 89 participants (68%) were women. Vitamin K antagonists were used by 16 participants and multivitamin supplements by 50 participants. No differences in change between intervention and placebo were found (−38.5 ± 389 vs. 4.5 ± 127 (pmol/L), p = 0.562). When excluding vitamin K antagonist users and multivitamin users, dp-ucMGP at follow-up was significantly higher in the vitamin D group (n = 40) compared to placebo (n = 30), with a difference of 92.8 (5.7, 180) pmol/L, adjusting for baseline dp-ucMGP and sex. In conclusion, vitamin D supplementation for six months did not affect vitamin K status; however, among participants without vitamin K antagonist or multivitamin use, vitamin D supplementation influenced dp-ucMGP concentrations.
