Bracken (Pteridium aquilinum, L. Kuhn), which is used widely in the Eastern and Western medicine and food, has attracted researchers interest. It is related with norsesquiterpene glucoside ptaquiloside, which is carcinogen, contained in the bracken. We quantitatively determined ptaquiloside in the subdued bracken, which is a way of decreasing or inactivating toxic effect and increasing the treatment activity in raw material of drug. The results showed the ptaquiloside was present in both samples, with sample 1 of 10.06 ug/g and with a minimum of 0,41ug/g in subdued sample 2. Therefore, the aim of the present study was to evaluate subdued sample 2 splenocyte proliferation assay using by MTT kit and splenocyte from Balb/c mice. MTT assay showed cell viability index of group of Соn A was 231,4 and cell viability index of preparation group was 233,7. Also, the group of Preparation with Con A was showed the high ability stimulate.

Эгэл бавран (pteridium aquilinum (l.) Kuhn)-гийн бэлдмэлийн дэлүүний эсийн хуваагдлыг олшруулах идэвхийг судалсан дүн

Өрнө, Дорнын анагаах ухаан болон хүнсэнд хэрэглэгдэж ирсэн Эгэл бавран (Pteridium aquilinum (L.) Kuhn) нь судлаачдын сонирхлыг ихээхэн татаж ирсэн билээ. Энэ нь түүнд агуулагдах норсесквитерпений бүлгийн гликозид болох птаквиклозид нь хорт хавдар үүсгэдэг (канцероген)-тэй холбоотой юм. Бид Эгэл бавранг уламжлалт аргаар номхотгол  хийж, Өндөр мэдрэмжит шингэний хроматографиар птаквиклозидын хэмжээг тодорхойлоход номхотгосон дээжинд 0.41 мкг/г, номхотгоогүй дээжинд 10.06 мкг/г хэмжээтэй птаквиклозид агуулагдаж байсан юм. Тиймээс номхотгол хийсэн  дээжний  дархлаанд үзүүлэх нөлөөг in vitro орчинд Balb/c үүлдрийн цагаан хулганы дэлүүний эсийг олшруулах идэвхээр МТТ өнгөт урвалын аргаар судлан тогтоов. Митоген буюу Соn A-тэй үүрний эсийн амьдрах чадварын индекс нь 231,4, загвар бэлдмэлтэй үүрний эсийн амьдрах чадварын индекс 233,7 байгаа нь хяналтын бүлэгтэй ойролцоо дүн үзүүлсэн байна. Харин бэлдмэлийг митогентэй хамт хэрэглэхэд эсийн амьдрах чадварын индексийг хамгийн их нэмэгдүүлж байна.

Published: June 2021

The purpose of this study was to compare the new technology methods of growing two-stem tomatoes with the method of growing one main stem during the testing of small fruit tomato varieties that are adapted to the soil and climatic conditions of Mongolia. When growing tomato varieties with 2 stems, Seminis-SV7160TC, Galaxy and TY Candy varieties had 169-171 days from germination to 80% of fruit ripening, which is 4-6 days later than growing with 1 main stem. When growing tomato varieties with 2 stems, it is possible to produce 10 or more stems per plant with 10 stems per plant or 10 stems per plant, but the delay in fruit ripening affected the yield and quality of the crop.

Жижиг жимст лоолийн (Lycopersicon Esculentum. Mill) сортуудыг 2 ишээр ургуулах шинэ технологийг туршсан дүнгээс

Монгол орны хөрс, цаг уурын нөхцөлд дасан зохицох жижиг жимстэй лоолийн сортуудыг сорих, туршихдаа шинэ технологиудын нэг  болох 2 ишээр ургуулах аргыг 1 гол ишээр ургуулах аргатай харьцуулан судлах зорилгоор энэхүү судалгааг явуулсан. Лоолийн сортуудыг 2 ишээр ургуулахад  Seminis-SV7160TC, Galaxy, TY Candy сортуудад соёололтын жигдрэлтээс үр жимсний болцын 80% хүртэлхи хугацаагаар тооцоход 169-171 хоног байсан нь  1 гол ишээр ургуулснаас 4-6 хоногоор оройтсон. Лоолийн сортуудыг 2 ишээр  ургуулахад   салаа иш тус бүрт 5 ш багцэцэг буюу 1 ургамалд 10 ш байхаар ургуулсан. Энэ арга нь  1 ишээр ургуулснаас 3 ш-ээр илүү  багц үр жимс авах боломжтой байсан ч үр жимсний боловсролтын хугацаа оройтсон нь ургацын хэмжээ, чанарт нөлөөлж байсан.

“Tú, como eres negra, harás de lobo”. El debate pendiente sobre la cuestión de la raza en España.
Authors: Rodríguez-García Dan , Habimana Jordana Teresa , Rodríguez Reche Cristina
Published: June 2021

En este artículo argumentamos que la idea de “raza” constituye un factor fundamental para la atribución de la pertenencia y el tratamiento social diferencial en España. Tras operacionalizar algunos conceptos clave (raza, racismo y racialización), ofrecemos una contextualización histórica y social sobre la construcción de la idea de raza en España, y aportamos datos sociodemográficos sobre la prevalencia del racismo en la sociedad española. En segundo lugar, aportamos información de tipo etnográfico. A través del análisis de narrativas de descendientes de uniones mixtas residentes en España, ejemplificamos hasta qué punto la idea de raza juega un papel central en las experiencias de estigmatización y discriminación de una parte cada vez más importante de la población española.
Pijos, progres y punks. Hacia una antropología de la juventud urbana
Authors: Feixa Pàmpols Carles
Published: June 2021

El artículo, originalmente publicado en 1989, es un esbozo de antropología de la juventud urbana, campo que el autor ha venido desarrollando desde entonces. Parte de una revisión bibliográfica de las principales aportaciones al estudio de las bandas y subculturas juveniles desde la antropología. Se centra en presentar los resultados de un trabajo de campo realizado en Lleida en 1984-85, focalizado en el análisis de los espacios de ocio nocturno y su vinculación con la emergencia de las llamadas “tribus urbanas”, representadas por las tres etiquetas que aparecen en el título: pijos, progres y punks. La observación participante en las rutas de ocio se combina con entrevistas en profundidad e historias de vida a jóvenes pertenecientes a estas subculturas. En la conclusión se retoma el debate sobre el ocio juvenil, a caballo entre la comercialización y la contestación, un debate que en plena era del coronavirus y del botellón sigue vigente.

Authors: Townsend Tainá Alves , Pedron Cristiane Drebes , Mazzieri Marcos Rogério
Published: June 2021

Objective of the study: This study aims to analyze scientific production about absorptive capacity and innovation in such a way as to make it possible to identify study trends and the theoretical bases on which they are based.Methodology / Approach: We performed bibliographic coupling, co-citation, and social network analysis on a sample of 3,698 articles, considering 2,778 articles from Web of Science and 920 articles from Scopus.Originality / Relevance: In a preliminary search, only two bibliometric works were identified that focused on absorptive capacity and innovation. However, since 2015, more than 1,500 articles have been published, with new perspectives, advancing studies on this topic.Main results: The coupling analysis resulted in six factors showing the trends of future studies. The co-citation analysis presented three factors, representing the intellectual structure arising from the coupling analysis. The network analysis provided insight into how these studies connect. The results point to trends in future studies that can fill the research gaps on absorptive capacity and innovation. In addition, we also indicate the theoretical fronts that can be used to explore these trends. Finally, we present a model that summarizes our findings and shows how they can contribute to the advancement of research based on the seminal model of Zahra and George (2002).Theoretical / Methodological contributions: We present a mapping of the theme that provides a clearer view of which seminal works are used to approach each theme to be explored in future studies, associating the results of the bibliometric techniques used.
Comparison of effects of low-level laser therapy and extracorporeal shock wave therapy in calcaneal spur treatment: A prospective, randomized, clinical study
Authors: Badil Güloğlu Sevtap , Yalçın Ümit
Published: June 2021

Objectives: In this study, we aimed to evaluate and compare the efficacy of low-level laser therapy (LLLT) and extracorporeal shock wave therapy (ESWT) in the treatment of calcaneal spurs.

Patients and methods: A total of 62 patients (14 males, 48 females; mean age: 47.6±11.7 years; range, 18 to 70 years) who were diagnosed with calcaneal spurs based on clinical examination and plain radiography between April 2019 and September 2019 were included in this study. A total of 15 sessions of plantar fascia gastroc-soleus stretching exercises and cold pack treatments were given to both groups. The LLLT (904 nm wavelength, 3,000 Hz, 8 J/cm2 dose to the painful heel area and insertion of the plantar fascia on the medial calcaneal area, five points for a total of 5 min for three weeks) was applied to the first group (n=31), whereas ESWT (10 Hz, 2,000 shock waves with a 2.5 bar pressure into the areas of the painful heel, insertion of the plantar fascia on the medial calcaneal area) was applied the second group (n=31). All patients were evaluated using the Visual Analog Scale (VAS) and Foot Function Index (FFI) before and after treatment.

Results: In both groups, the median VAS and FFI scores after treatment showed a significant improvement, compared to pre-treatment scores (p=0.001). There was no significant difference between the groups in terms of the median post-treatment VAS scores (p>0.05). In the ESWT group, the median FFI pain and total scores after treatment were significantly lower than in the LLLT group (p=0.033). The change in the median FFI pain and total scores were significantly higher in the ESWT group (p=0.046).

Conclusion: Both treatment modalities are effective and not superior to each other in terms of disability and activity limitation reduction, although a greater improvement in the FFI pain and total scores can be achieved with the ESWT. Based on these findings, we recommend both non-invasive treatment methods to be used in the treatment of calcaneal spurs in the clinical practice.
Politische Theologie als Rechtswissenschaftstheorie. Kommentar zu Jean-François Kervégan
Authors: Auer Marietta
Published: June 2021

In her contribution, Marietta Auer takes up Jean-François Kervégan’s call to decontextualize Schmitt and to take up and modify individual aspects of his writings. Auer addresses the problem of a specifically jurisprudential epistemology and thus of the nature of the object and methods of jurisprudential knowledge. At issue is here nothing less than the question of the scientific nature of the science of law.
Legalität als Waffe? Zur Dialektik von Entlegitimierung und Relegitimierung der Legalität bei Schmitt und Kervégan
Authors: Günther Klaus
Published: June 2021

In his contribution, Klaus Günther deals with Schmitt’s distinction between legality and legitimacy. According to Günther, Kervégan’s decontextualization of the distinction first requires a recontextualization. Thus, he shows to what extent it is underlaid, even interwoven, with another distinction, namely with the distinction between pays réel and pays légal. It has been coined by the political opposition against the principles of 1789 and determines the conceptual framing of law, democracy and human rights until today. Above all, it obfuscates their interrelationships and blocks an adequate conception of legitimacy by legality.
The Search for the Absolute
Authors: Anderson Owen ,   Philosophy Documentation Center
Published: June 2021

Contemporary Analytic Philosophy finds itself within a historical context, answering questions that have been handed to it by earlier philosophers. Specifically contemporary Analytic Philosophy finds itself responding to the Idealists of the nineteenth century in the hope of justifying the "new science" that seems to give us so many practical benefits. In doing this, questions arise as to how contemporary Analytic Philosophy will answer the problems that Idealists struggled with. In thefollowing, a brief overview of the Idealist enterprise will be contrasted with two contemporary Analytic Philosophers, namely Rudolf Carnap and W.V. Quine, in order to understand how the latter two deal with the philosophical problems handed to them by their tradition. Specifically, the question of universals and their relation to the absolute, and the assumption behind this concerning intuition are going to be investigated. This article will argue that the Idealist tradition raised important questions that Carnap and Quine were not able to answer. It will critique Carnap and Quine as failing to find the universal required for thought and propose an alternative pathway to finding the solution.
The Return of the Relative
Authors: Tonner Phillip ,   Philosophy Documentation Center
Published: June 2021

In this paper we explore the complex relationship between the philosophies of Sir William Hamilton and Henri Bergson. We then place these philosophies in a critical relation to French phenomenological philosophy, particularly, Merleau-Ponty's. By so doing we examine a historical and theoretical 'ark' that rises in 19th Century Scotland and falls in 20th Century France, an ark that has received little attention hitherto by historians of philosophy. Our aim is to open up a new dimension of these philosophies and provoke a fresh debate over their relationships and the philosophical tensions that exist between them.
Electrocambalidae fam. nov., a new family of Cambalidea from Cretaceous Burmese amber (Diplopoda, Spirostreptida)
Authors: Moritz Leif , Wesener Thomas
Published: June 2021

A new family, Electrocambalidae fam. nov. of the suborder Cambalidea is described from Cretaceous Burmese amber based on two new genera, Electrocambala gen. nov. and Kachincambala gen. nov. with four new species, Electrocambala ornata gen. et sp. nov., E. cretacea gen. et sp. nov., Kachincambala muelleri gen. et sp. nov. and K. distorta gen. et sp. nov. The specimens are described combining classical light microscopy with drawings and photography, and modern micro-computed tomography (μCT). Morphological characters otherwise obscured are examined and visualized by creating volume renderings and 3D-segmentations from μCT data. Electrocambalidae fam. nov. is characterized by the following character combination: (1) a forward shift of leg pair 3, resulting in an apparently legless 3rd body ring, (2) presence of metazonital setae, and (3) extensive pilosity on the head. Although some of these characters are shared with other Juliformia they are unique in this combination. The described fossils are the oldest and first Mesozoic Spirostreptida and Cambalidea known and ca 70 million years older than previous records of the group.
Richard Flury and the politics of the unpolitical
Authors: Walton Chris
Published: June 2021

During the Second World War, composers in neutral Switzerland were not faced with the same difficult choices as their colleagues in occupied Europe, but most nevertheless refused to do anything to antagonise the neighboring fascist regimes. The Swiss composer Richard Flury (1896-1967) was an exception: he worked with numerous anti-fascists and Jewish emigrés and even offered a job to his friend, the conductor Gottfried Kassowitz, in an (unsuccessful) effort to get him out of Nazi-occupied Vienna.
Recycled/remediated/reformatted: Goran Bregović's appropriation of the music industry strategies in pop song (post)production
Authors: Mikić Vesna
Published: June 2021

This paper is based on the assumption that Goran Bregović's transition from Yugoslav rock star to contemporary Balkan composer, as he defines himself today, has unfolded via the appropriation of the different strategies the music industry (M I) devised in its own, bumpy and often contested, but undeniably technologically constituted transition and transformation during the last decades of the 20th and at the beginning of 21st centuries. Notable for his usage of existing (mainly traditional) music even in his rock years, Bregović actually developed some peculiar modes of production that almost neatly matched the MI strategies not only of production but of distribution and consumption as well. Hence, I shall address the possibilities of interpreting Bregović's creative/production procedures, here defined as recycling, remediation, and reformatting as appropriated music industry production, distribution and, naturally consumption strategies, show-casing his music for Emir Kusturica's Underground and the pop song(s) emerging from it.

Authors: Gajić Milica
Published: June 2021

This year's jubilee of the National Theatre in Belgrade is an opportunity to remind ourselves of the presence and contribution of Czech musicians at that institution. We meet them as members of the orchestra, bandleaders, authors of operas, operettas, and stage music, and, to a lesser extent, as vocal soloists in numerous works of stage music and chamber musicians. Many of them showcased their concert activities on the stage of this institution, including even some who were internationally renowned musicians at the time.
Pattern, form and silence in Amalgamations, an extended duration work
Authors: Stone Sophie
Published: June 2021

The article examines Sophie Stone's composition Amalgamations (2016), an extended duration work for solo organ. Pattern is explored in the form of both the notation and performance of the piece. The notation comprises verbal and graphic notation, with many possible combinations of instructions resulting in sustained sounds and silence. Amalgamations is non-linear and non-teleological. Tim Ingold's notion of "wayfaring" provides a way of understanding how a performer may negotiate the notation. Due to the improvisatory and aleatoric elements of the piece, each performance will be different. Numerous types of silences will result from performances of Amalgamations and the experience of these silences are different and are determined by the sounds surrounding them.
Srpska umetnička muzika kao deo fonda Muzikološke biblioteke Filozofskog fakulteta u Ljubljani - opis i kritički osvrt
Authors: Marinković Miloš
Published: June 2021

U radu se razmatra heterogena građa srpske umetničke muzičke baštine, pohranjena u Biblioteci Katedre za muzikologiju Filozofskog fakulteta u Ljubljani (Oddelek za muzikologijo, Filozofska fakulteta, Univerza v Ljubljani). Činjenice da je ova katedra trideset godina delovala u okvirima jugoslovenske federacije, pri čemu je bila i prva katedra u tadašnjoj državi s mogućnošću izvođenja doktorskih studija, navode na pretpostavke o bogatoj opskrbljenosti njenog bibliotečkog fonda građom koja pripada srpskoj muzičkoj kulturi. Na osnovu popisa i analize građe o srpskoj umetničkoj muzici, u radu se postojeći materijali razvrstavaju u tri odvojene zbirke: Muzikološku knjižnu zbirku, Notnu zbirku i Zvučnu zbirku. Kritičkim uvidom u svaku od njih, ukazuje se na potencijale ljubljanske muzikološke biblioteke, kao svojevrsne 'baze podataka' za upoznavanje ili istraživački pristup umetničkoj muzičkoj kulturi Srbije.
The early development of the synthesizer and its impact on contemporary popular music: A research sketch
Authors: Cvejić Žarko
Published: June 2021

The synthesizer played a central role in Western popular music of the 1960s, 1970s, and well into the 1980s, especially in so-called progressive rock and synth pop. And yet, there is still no book-length study of its impact on and meanings in this repertory. This text is a discussion of the main issues that such a study would have to address, along with a brief historical survey of the emergence and early development of the synthesizer.

Authors: Knežević Darija , Trifunović Silvana , Jović Duška , Stanisavić-Šimić Jadranka
Published: June 2021

Introduction: Patients in intensive care units (ICUs) are at higher risk of infections due to invasive procedures and antibiotic therapy. Infections caused by multidrug-resistant (MDR) bacteria represent a global problem, limiting the choice of antimicrobial therapy. Objective: To determine the rate of infections in ICUs, as well as the type of MDR bacteria associated with such infections. Material and methods: The study included strains of MDR bacteria isolated from laboratory samples of hospitalized patients in surgical ICUs in a one-year period. All strains of MDR bacteria were isolated and identified by standard microbiological methods for aerobic bacteria according to the recommendations and guidelines are given by the Clinical and Laboratory Standards Institute (CLSI). Results: Infections caused by MDR bacterial isolates were confirmed in 199 (19.17%) patients in ICUs. The frequency of Gram-negative isolates was significantly higher than Gram-positive (88.35% and 11.65%, p <0.001). The most common infections in ICUs caused by MDR bacteria were respiratory tract infections (49%), followed by soft tissue and skin infections. The CDI incidence density 1.13 cases/10,000 patient-days. Conclusion: A high frequency of infections caused by MDR bacteria was found with patients in ICUs, and respiratory tract infections dominated. Information on the types of infections and pathogens can help develop policies for prevention, diagnosis, treatment, and resource allocation.

The objective of this article is to examine the relationships between organizational values and the performance indicators of an organization. Two work teams were analyzed in a restaurant. To achieve the objective, a Delphi method was developed that allowed knowing the level of consensus of the members of the teams studied among a group of previously identified values, allowing to identify those values that had greater importance and regulation for each team. Through the Mann-Whitney statistical test, the relationship between values and customer satisfaction and productivity were examined, aspects that were measured in the organization studied for each work shift, where the teams analyzed worked. The research made it possible to prove the relationship between values and customer satisfaction directly and productivity indirectly, demonstrating that the work team showed greater consensus on its values in terms of importance and level of regulation showed better results in the dependent variables analyzed. The research carried out allowed the quantitative validation of the hypothesis that the shared values that regulate the behavior of the employees studied are closely related to the performance indicators.

The Sharing Economy is a fastest growing and heavily debated Socio economic model. In the platform-based sharing economy, the provider provides the service and the consumer using the service from a two-sided market. However, there is a lack of studies that cover the both sides of platform based sharing market. This study aims to examine the effect of Indulgence, trust, economic benefit, social interaction, enjoyment and sustainability on user and provider intention to engage in peer-to-peer sharing. This explanatory study uses a quantitative methodology involving data collection through structured questionnaire from service users (n=220) and service providers (n=170) of Uber and Careem by adopting snowball sampling technique. Structured Equation Modeling (SEM) was applied to analyze data by using AMOS 24. The empirical results of this study indicate that indulgence, social interaction, economic benefit and enjoyment have significant positive association with user and provider intention. Further, a positive relationship was found between provider trust in user and provider intention to engage in peer-to-peer sharing. This study makes its significant contribution by providing new insights to literature and practice by studying two sided market. In addition the study explored the effect of indulgence on peer-to-peer sharing intention which is found yet to be explored in the literature. This study suggests practical implications for the Marketing managers to develop effective platform business strategies and marketing campaigns in accordance with the individuals' intention to engage in sharing.
The digital transformation program management in medium-sized businesses: A network approach
Authors: Anshin Valery , Bobyleva Alla
Published: June 2021

The article deals with the process management's issues of digital transformation in companies. The emphasis is made on the consideration of program's projects as interrelated components with the features of emergency system, not as a weakly interconnected complex (linear set) of projects. Authors propose the organizational model of transformation's program management and the new approach to prioritizing projects based on the use of network analysis. The suggested method allows to evaluate the role of the project in the transformation program and its impact on the other projects, as well as its impact on the planned benefits of the program. It also allows to distribute resources between projects and to assess the risks of the program as a whole. The article focuses on the differences of medium-sized companies' management methods, on the one hand, from companies in small business, and on the other hand, from large companies. The application of the method was tested at a medium-sized poultry farm. The analysis of projects of the real program was made, the network model of the program was built, and the probability of projects' and the program at all success was estimated. The evaluation of the program indicators allowed the authors to make conclusions about priorities of separate projects. The proposed approach can be used in various companies, regardless of industry affiliation.
ФОРМИРАЊЕ УНИВЕРЗИТЕТА У САРАЈЕВУ РЕПУБЛИКЕ СРПСКЕ (1992–1997)
Authors: Мастиловић Драга В.
Published: June 2021

Универзитет у Сарајеву Републике Српске или Уни- верзитет у Источном Сарајеву, како се данас назива, рађао се, стасавао и развијао упоредо с Републиком Српском, и то као једна од њених најзначајнијих институција. Његово фор- мирање било је условљено изласком из Сарајева више сто- тина универзитетских професора и неколико хиљада студе- ната српске националности, након избијања ратних сукоба 1992. године, а који су свој рад и образовање жељели да наставе у Републици Српској и поред ратних услова. Универ- зитет у Сарајеву Републике Српске настао је одлуком о издвајању из дотадашњег Универзитета у Сарајеву, коју је до- нијела Народна скупштина Републике Српске 1992. године. Услиједио је мукотрпан процес организовања факултета и покретања наставе у најтежим могућим, ратним условима, у објектима који су неријетко били веома близу линије фронта и изложени непријатељској артиљеријској пјешадијској ватри. Ипак, у таквим, скоро немогућим условима, Универ- зитет у Сарајеву Републике Српске опстао je и заживио.
ПРИЛОГ ПРОУЧАВАЊУ ЈУГОСЛОВЕНСКЕ ИДЕЈЕ: КОСОВО КАО ПРЕДМЕТ ИЗВЕШТАВАЊА ШТАМПЕ НА ПРОСТОРУ ДАНАШЊЕ ХРВАТСКЕ 1835–1918. ГОДИНЕ

Рад указује на развој југословенске идеје на терито- рији данашње Хрватске 1835–1918. Заснован је, превас- ходно, на критичкој анализи штампе хрватске провенијен- ције у датом периоду, тачније чланака у којима се помиње Косово. Оно се више посматра као митски (историјски) сим- бол јужнословенских народа него што се, пак, анализирају и тумаче историјски догађаји на том подручју кроз прошлост. То и не чуди ако имамо у виду актуелност југословенске иде- је на просторима данашње Хрватске кроз XIX век и прве де- ценије наредног. Након 1918. Косово убрзано нестаје из ви- докруга хрватске штампе, која се у новим политичким окол- ностима фокусирала на српско-хрватски сукоб, а, сходно томе, југословенска идеја није више деловала привлачно као раније.

ИДЕАЛНА СФЕРА И СЛОЈЕВИТА СТРУКТУРА БИТКА: ОНТОЛОШКИ СТАТУС МОРАЛНИХ ВРИЈЕДНОСТИ У ФИЛОЗОФИЈИ НИКОЛАЈА ХАРТМАНА

Published: June 2021

Питање постојања моралних вриједности јесте онтолошко. Да би етика оправдала своје морално суђење, она се претходно мора онтолошки утемељити. Овај рад анализира онтолошки статус идеалне сфере и моралних вриједности у слојевитој изградњи битка у дјелу Николаја Хартмана. Хар- тманов мисаони пут полази од спознаје бића као таквог, пре- лази на одређење битка и његових манифестација, обавља категоријалну анализу те излаже специфичност онтичких слојева. Метафизиком спознаје жели показати да је могућа спознаја трансцендентног битка. Нова онтологија ослобо- ђена грешака старе, битак ће видјети у пуној комплексности анализом категорија и изградњом слојева. Битак je гене- рално биће и одређује се с обзиром на његове аспекте (мо- дусe, начинe и модалитетe). Категорије схвата као најоп- штије реалне конститутивне принципе и дијели их у три групе: модалне категорије, фундаменталне категорије и спе- цијалне категорије слојева (анорганског, органског, душев- ног и духовног). Пошто онтологију сматра истовјетну с фи- лозофијом, предмет етика спецификује само један онтички слој – идеалну сферу и моралне вриједности. Положај вриједности може се разумјети једино у контексту цјелокуп- ног онтолошког система слојевите структуре битка. Човјек је разапет између царства реалних бића и царства идеалних вриједности. Идеални битак налази се као основа у реалном, али се у њему потпуно не исцрпљује. Вриједности спозна- јемо емоцијама и можемо им приступити објективно и субјективно. Да би вриједностима дао структуру, Хартман уводи два обрнуто пропорционална закона: закон вриједносне ја- чине и закон вриједносне висине. Хартману припада заслуга што враћа онтологију на велика врата у филозофију у вре- мену краја метафизике. Можемо рећи да Хартманова мисао садржи своје антиномије, али да је број њених позитивних и поучних елемената далеко већи и значајнији.
Resoconto sul Convegno Internazionale in video-conferenza Rome Education Forum 2020 «Didattiche e didattica universitaria: teorie, cultura, pratiche alla prova del lockdown da Covid-19»

The learning processes of the academic year 2019/2020 were characterized by a great change: the general suspension of teaching in presence and the synchronous and asynchronous start of lessons due to the spread of the Sars-Cov-2 virus (Covid-19). This change required teachers of all types and institutional grades to re-design educational activities using information and communication technologies. The International Conference on «Didactics and university didactics: Theories, cultures, practices» at the test of the Covid- 19 Lockdown, had as its objective the comparison between experts who have returned, on the basis of empirical evidences, a picture of the impact that the use of ICT has determined on the learning and socialization of pupils and on the autonomy of the various scholastic and university institutions.

The pre-Bötzinger complex, which is located at a ventrolateral medulla of human and mammal, is considered to be the center for the generation of respiratory rhythms. In a normal state, the respiratory rhythm is uniform and orderly. Otherwise, the respiratory rhythm will change to a pathological state. Therefore, the monitoring of respiratory rhythm is of great significance in monitoring the health. In this paper, according to a two-coupled model of pre-Bötzinger complex with calcium ion current, we investigate the generation and transition mechanism of anti-phase bursting synchronization by using phase-plane analysis, bifurcation and fast-slow decomposition. It is found that the pre-Bötzinger complex model can exhibit mixed bursting when calcium ion concentration is at steady state, which indicates that the oscillation of calcium is not a necessary condition for the generation of mixed bursting. This is quite different from the results obtained in previous studies, indicating that the mixed bursting is caused by the periodic fluctuations of calcium. The methods used in this paper can provide a new idea for investigating the dynamics of mixed bursting, and it can also be applied to the study of other neuronal systems on a multiple time scale.

 Ultraviolet photodetector plays an important role in fire warning, missile tracking and dose detecting of ultraviolet sterilization and disinfection, which is closely related to human lives. With the development of integrated detection system, the requirements for the size and energy consumption of the detector are becoming more and more stringent. Traditional detector that requires an external power supply can no longer meet these requirements. Moreover, a traditional ultraviolet detector is mainly composed of first-generation semiconductors and second-generation semiconductors. These semiconductors have small band gaps and large cut-off wavelengths, and are more suitable for infrared detection. When used for implementing the ultraviolet detection, an additional layer is often required, which increases not only the volume but also the cost.

 Gallium nitride (GaN), as a third-generation semiconductor, has a band gap of 3.4 eV and a corresponding absorption edge of 365 nm. It is a natural ultraviolet detection material. At the same time, the excellent physical and chemical properties make the devices prepared by GaN have high stability. In recent years, some studies have shown that the GaN-based ultraviolet photodetectors have excellent responsiveness, but each of these detectors usually requires an external bias and has a slow response speed. Here, we propose a high responsivity, fast response speed and self-powered ultraviolet photodetector based on NiO/GaN p-n junction. By using the magnetron sputtering, a layer of 70 nm thick p-NiO film is deposited on a high-quality n-GaN film that has been grown on a sapphire substrate by the metal-organic chemical vapor deposition. The fabricated p-n junction shows obvious rectification characteristics at ± 0.5 V. Due to the existence of the built-in electric field, the device can work without externally applied bias. Under zero bias, the detector shows a responsivity of 272.3 mA/W for 365 nm ultraviolet light while the intensity is 50 μW/cm2, and has a detectivity as high as 2.83 × 1014 Jones. This indicates that the detector has a high sensitivity even for very weak light. Owing to the good crystallinity of the film, the dark current is as low as 10–10 A, the switching ratio is > 103, and the response speed reaches 31 ms. These excellent properties show the broad application prospects of the devices based on NiO/GaN p-n junctions in the field of self-powered ultraviolet detection, and thus providing new ideas for the future development of intelligent integration.
Nurse educators perceptions of simulation teaching in Chinese context: benefits and barriers

Published: June 2021

Background

Although simulated teaching was introduced to China in the 1990s, it remains underused in nursing education. Determining how Chinese nurse educators feel about using simulation in their institutions is very important for faculty training and has the potential to influence simulation implementation.

Method

This cross-sectional descriptive study was undertaken to identify the nurse educators’ experiences in the use of simulation from various regions of China. One hundred and thirty-six nurse educators provided demographic data and information about simulation implementation within their institutions and explored the perceived barriers and benefits of simulation usage.

Results

The survey data shows that 108 participants have used simulation in their work, but less than 92 (67.6%) of the respondents had used this teaching strategy more than ten times in last year. The study identified four factors hindering nurse faculty from simulation adoption: (1) concerns with student readiness; (2) the need for faculty team-building for simulation teaching; (3) lack of adequate simulation resources; and (4) thoughtful integration of simulation into nursing curricula.

Conclusions

Study data suggest that faculty training programs for simulation should be based on the nurse educators’ training needs, including systematically designed training topics, and the provision of hands-on learning simulation activities with expert feedback to help nurse educators achieve the competencies required for effective simulation-based education.

The Upper Cretaceous ‘upper’ Winton Formation of Queensland, Australia is world famous for hosting Dinosaur Stampede National Monument at Lark Quarry Conservation Park, a somewhat controversial tracksite that preserves thousands of tridactyl dinosaur tracks attributed to ornithopods and theropods. Herein, we describe the Snake Creek Tracksite, a new vertebrate ichnoassemblage from the ‘upper’ Winton Formation, originally situated on Karoola Station but now relocated to the Australian Age of Dinosaurs Museum of Natural History. This site preserves the first sauropod tracks reported from eastern Australia, a small number of theropod and ornithopod tracks, the first fossilised crocodyliform and ?turtle tracks reported from Australia, and possible lungfish and actinopterygian feeding traces. The sauropod trackways are wide-gauge, with manus tracks bearing an ungual impression on digit I, and anteriorly tapered pes tracks with straight or concave forward posterior margins. These tracks support the hypothesis that at least one sauropod taxon from the ‘upper’ Winton Formation retained a pollex claw (previously hypothesised for Diamantinasaurus matildae based on body fossils). Many of the crocodyliform trackways indicate underwater walking. The Snake Creek Tracksite reconciles the sauropod-, crocodyliform-, turtle-, and lungfish-dominated body fossil record of the ‘upper’ Winton Formation with its heretofore ornithopod- and theropod-dominated ichnofossil record.
