Authors: Atik Ezgi , Gorucu‐Coskuner Hande , Taner Tulin
Published: May 2020

The aims of this study were to evaluate the effects of a live‐video teaching tool on the performance of dental students in bending an orthodontic vestibular arch and to assess the students’ perceptions of the technology. All 135 fourth‐year dental students in the 2018 academic year at Hacettepe Dental School, Ankara, Turkey, were invited to participate in the study; after exclusions, the remaining 116 were randomly divided into two demonstration cohorts. These students had no prior experience bending an orthodontic wire. Cohort 1 (control, N=58) was shown a conventional live demonstration of the orthodontic bending of a vestibular arch, and Cohort 2 (experimental, N=58) was shown a live‐video demonstration of the same procedure. Both cohorts saw the demonstration before beginning the exercise and were evaluated afterwards on their performance of the procedure. In addition, the students’ perceptions of the demonstration techniques were collected with a questionnaire. The results did not show any significant differences in the students’ bending scores between the control and experimental cohorts (p=0.767). The median values on the questionnaire indicated almost no statistically significant difference in responses between the cohorts. The only significant difference was that Cohort 1 had a higher percentage who answered “yes” they would like to rewatch the demonstration than did Cohort 2 (p=0.024). In this study, the live‐video technique was found to be as effective as a conventional live demonstration for orthodontic practical education, suggesting that either technique could be used as an appropriate method for training in orthodontic wire bending.

Published: May 2020

The aims of this study were to compare third‐year dental students’ satisfaction and level of learning in case‐based learning (CBL) versus team‐based learning (TBL) and the resources required in those two methodologies. Level of learning was assessed for both knowledge and application, and resources were defined as student and faculty time and rooms. In academic year 2018‐19, all 68 third‐year dental students in one U.S. dental school were enrolled in two sequential semester‐long courses; the first used CBL, and the second used TBL. After each course, students and faculty facilitators completed surveys, and data from students’ knowledge and application exams were collected. The student surveys asked students to report their satisfaction with the learning methodology (CBL or TBL); the faculty surveys asked the faculty facilitators to report the resources used for each methodology. Forty‐five of 68 students (66%) consented to participate; however, a larger number of students completed surveys in the two semesters (69% for CBL and 87% for TBL). Fourteen of 16 (88%) faculty facilitators completed the CBL survey, and five of the six (83%) completed the TBL survey. Overall, the results showed that students’ satisfaction was higher with CBL than TBL (Mann‐Whitney U = 882.0; p<0.001), and students reported having a better understanding of concepts after CBL than TBL (U = 899.0; p<0.001). The students performed better on knowledge exam items in TBL than CBL (86% vs. 82%) but the same on application items (both 86%). Resource requirements for both methods were extensive, with TBL requiring fewer facilitators and rooms than CBL but requiring more time from both students (2.6 vs. 2.3 hours weekly) and faculty members (2.3 vs. 1.4 hours weekly). In this study, students preferred CBL to TBL but had higher knowledge scores in the TBL course. The resources needed for both CBL and TBL were said to be extensive, with infrastructure use higher for CBL but time for students and faculty higher for TBL.

Published: May 2020

This paper describes a low-cost solar panel simulator for Maximum Power Point Tracking (MPPT) method testing, especially under partially shading conditions. The simulator consists of a DC power supply and a solar panel. The simulator works to emulate the characteristics of solar panels without depending on artificial illumination or sunlight. The simulator can represent the needed irradiation through the settings on the DC power supply. The experimental setup is developed to emulate the characteristics of solar panels at Standard Test Conditions (STC) irradiation conditions as well as varying irradiation conditions. Testing is done to emulate irradiation varies from 200-1,000 W/m2. To emulate the characteristics of solar panels in partial shading conditions, two DC power supply units and two solar panels are used. Each solar panel is simulated to receive different solar irradiations. The test results show that the simulator can emulate the characteristics of solar panels under partial shading conditions which has several maximum power points. Furthermore, partial shading conditions are simulated under varying irradiation conditions which resulted varying maximum power point values.

Authors: Abdurrahman Mulyadi Rasheed , Agy Ramdhan Muhammad , Syihabuddin Budi , Olivia Nur Levy
Published: May 2020

In the last decade, planar electromagnetic (EM) wave absorbers began to be widely studied. This type of EM wave absorber is thin, flexible, and easy to fabricate, which allows absorber to be used in new future applications. Split Ring Resonators (SRR) are one of many forms of absorber that is known to have an excellent absorbance performance. In this paper, square patch absorber, Axial Symmetric SRR (AS-SRR), and Axially Asymmetric SRR (AAS-SRR) are designed and observed in C-Band. From the simulation results, we obtained a square cell size of 30 mm, AS-SRR of 20 mm, and AAS-SRR of 18 mm. The three forms can reach absorption rates above 92%, with a bandwidth of 0.055 GHz, 0.076 GHz, and 0.081 GHz, respectively. Furthermore, the AAS-SRR design parameters were characterized, and the main parameters that influence the bandwidth and resonant frequency are the resonator length and resonator thickness. The maximum bandwidth of the characterization is 0.087 GHz.
Formulating Indonesia’s Covid-19 Policy based on South Korea’s Experience
Authors: Rafikasari Astri
Published: May 2020

This paper aims to analyze the formulation of Indonesian policy in overcoming Covid-19. The policy formulation is based on the experience of South Korea that has successfully overcome Covid-19 in its country. By using descriptive research methods, using data sources from books, journals, and writings related to Covid-19. The massive distribution of Covid-19 in Indonesia has encouraged the government to formulate appropriate and accurate policies to address Covid-19 in Indonesia. In formulating the policy, it can be based on the experience of other countries that have been successfully applied. South Korea as one of the countries that have successfully overcome the spread of Covid-19 by utilizing technology should be used as an example of learning. South Korea utilizes state technology (smart city infrastructure) in tracking Covid-19 patients. Through this tracking process, the spread of Covid-19 can be reduced. For Indonesia, the South Korean experience regarding the use of various technologies to detect Covid-19 patients and their distribution is now important for Indonesia. Tracking via credit/debit card transactions, tracking cellphone history (calls, text message, Whatsapp, etc.), cellphone GPS tracking, tracking through social media (Instagram, Twitter, Facebook, etc.), as well as tracking on start-up applications such as Gojek and Grab will make it easier for the government to be able to detect and suppress the distribution of Covid-19. The development of Covid-19 applications will also be more comprehensive in dealing with Covid-19 in Indonesia

Aim:
To assess the potential of biomarker triage testing (BM-TT) in the Dutch colorectal cancer (CRC) screening program.
Materials & methods:
Using the Adenoma and Serrated pathway to Colorectal CAncer model, we simulated fecal immunochemical test (FIT)
47
-screening and various FIT plus BM-TT screening scenarios in which only individuals with both a positive FIT and BM-TT are referred to colonoscopy.
Results:
Adding a low polyp sensitivity BM-TT to FIT-screening reduced colonoscopy burden (89–100%) while increasing CRC mortality (27–41%) compared with FIT
47
-screening only. The FIT plus high polyp sensitivity BM-TT scenarios also decreased colonoscopy burden (71–89%) while hardly affecting CRC mortality (FIT
47
0–4% increase, FIT
15
2–7% decrease).
Conclusion:
Adding a BM-TT to FIT-screening considerably reduces colonoscopy burden, but could also decrease screening effectiveness. Combining FIT
15
with a high polyp sensitivity BM-TT seems most promising.

Scaling of variational quantum circuit depth for condensed matter systems
Authors: Bravo-Prieto Carlos , Lumbreras-Zarapico Josep , Tagliacozzo Luca , Latorre José I.
Published: May 2020

We benchmark the accuracy of a variational quantum eigensolver based on a finite-depth quantum circuit encoding ground state of local Hamiltonians. We show that in gapped phases, the accuracy improves exponentially with the depth of the circuit. When trying to encode the ground state of conformally invariant Hamiltonians, we observe two regimes. A finite-depth regime, where the accuracy improves slowly with the number of layers, and a finite-size regime where it improves again exponentially. The cross-over between the two regimes happens at a critical number of layers whose value increases linearly with the size of the system. We discuss the implication of these observations in the context of comparing different variational ansatz and their effectiveness in describing critical ground states.

Authors: Castro-Buitrago Érika , Vélez-Echeverri Juliana , Madrigal-Pérez Mauricio
Published: May 2020

La introducción de la gobernanza del agua en el ordenamiento colombiano y la alta conflictividad socioecológica motivan los análisis que vinculan la naturaleza con los derechos humanos. Desde una investigación de corte dogmático descriptivo y analítico, este artículo propone el relacionamiento de la gobernanza del agua con los derechos humanos por medio de la integración de una serie de estándares jurídicos vinculados al Acuerdo de Escazú y al derecho humano al agua. Entre los hallazgos se identificaron: la deficiente reglamentación de la participación y del acceso a la información, la falta del financiamiento público, la limitación de la deliberación, la desmotivación de la concertación y la falta de integración efectiva de los grupos en condición de vulnerabilidad. Los objetivos de la gobernanza del agua, materializados en los Consejos de cuenca, se relacionan con los estándares jurídicos integrados y los hallazgos obtenidos.

Authors: Parra Báez Angélica María , Vargas Espitia Liliana Andrea , Woolcott Oyague Olenka
Published: May 2020

En Colombia la responsabilidad social empresarial (RSE) ha tenido un lento avance. La mayoría de los empleadores carecen de conciencia colectiva que les permita entender su papel en la sociedad y la labor fundamental que realizan al generar puestos de trabajo, especialmente para aquellas personas en situación de discapacidad o con diversidad funcional. Desde la Corte Constitucional, ha sido señalado que el rol de la empresa y de la libertad de competencia debe contrastarse con la función social, en el marco de un Estado social de derecho. El presente artículo tiene por objeto revisar el papel de los empleadores en un mundo que hoy en día se debate entre la globalización, el fortalecimiento de bloques regionales y el nuevo nacionalismo, lo que genera formas diversasde trabajo, de trabajadores y de modalidades de contratación y amplía los conceptos tradicionales en el ámbito laboral donde cambia el verdadero papel del empresario en la inclusión de personas en situación de discapacidad.
¿Cuáles son las exigencias de los pueblos latinoamericanos? Llegar a ser algo
Authors: Mendieta González David
Published: May 2020

Cuando se escribe este editorial, América Latina está convulsionada. Movimientos sociales se han puesto en marcha en Perú, Ecuador, Chile y Colombia para expresar su inconformidad con gobiernos de derecha e izquierda. Mucho se ha escrito en los últimos años acerca de la crisis de la democracia (Levittsky y Ziblatt, 2018; Mendieta, 2019). ¿Pero están las democracias latinoamericanas en crisis o ni siquiera hemos podido consolidarlas pues siguen siendo las democracias de unos pocos? Tenemos gobernantes elegidos democráticamente, pero también necesidades básicas insatisfechas, pobreza, desigualdad y falta de oportunidades.
Colonialidade e feminicídio: superação do “ego conquiro” como desafio ao Direito
Authors: Pires Marques Clarice Gonçalves
Published: May 2020

O presente estudo pretendeu identificar em que medida a colonialidade, no que diz respeito à ética/não ética de guerra, contribui para o fracasso na redução do feminicídio no país. Analisou-se também o perfil do tipo de feminicídio predominante no Brasil, qual seja o feminicídio doméstico ou íntimo. Verificouse que há carência de articulação entre o sistema de registro de óbitos e a caracterização desse tipo de crime a fim de evitar a invisibilidade e subnotificação dos casos de assassinatos de mulheres que possam ser confundidos com casos de mortes não ocasionadas em razão do gênero. Notou-se que as estratégias de dominação/guerra e violência repercutem até a atualidade por meio da colonialidade/colonialidade do Direito, e mantêm as desigualdades de poder entre os gêneros e mesmo com um sistema protetivo formado pelaLei 11.340/2006 e Lei 13.104/2015, não houve redução do genocídio feminino. A proposta metodológica é a dos Estudos Decoloniais, que compreende criticamente o objeto de estudo, bem como se vale da técnica de pesquisa bibliográfica e documental.
Retos del posconflicto frente a la respuesta humanitaria: entre la persistencia de las consecuencias humanitarias y las limitaciones al mandato de los actores humanitarios
Authors: Valencia Londoño Paula Andrea
Published: May 2020

El acuerdo de paz entre el Gobierno de Colombia y las Fuerzas Armadas Revolucionarias de Colombia-Ejército del Pueblo (FARC-EP) se firmó en el año 2016. A pesar de que este marcó un hito en la historia del país y constituye un paso importante en la búsqueda de salidas negociadas al conflicto armado y la reducción de la violencia, ha traído en el periodo de posacuerdo un proceso de desestabilización sociopolítica que ha derivado en múltiples vulneraciones de los derechos humanos, tanto en zonas rurales como urbanas. Estas se expresan en la persistencia de consecuencias humanitarias que, aunque ya no se derivan de una situación de conflicto armado no internacional, sino de la confrontación entre actores armados ilegales vinculados con el crimen organizado, son clara expresión del impacto de la lucha armada sobre la población civil. En múltiples ocasiones, estas consecuencias han llegado a niveles equiparables a los de las manifestaciones presentes en situaciones de conflicto armado. No obstante, cada vez la respuesta humanitaria amparada por el espectro normativo del DIH es más limitada, lo que hace que esta se convierta en uno de los principales retos de la etapa del posconflicto.

La (in)soportable levedad de la educación no formal y las realidades cotidianas de la educación social
Authors: Caride José Antonio
Published: May 2020

Situamos nuestros argumentos en la necesidad de revisar críticamente tres expresiones (educación “formal”, “no formal” e “informal”) que han adquirido un notable, e injustificado, protagonismo en los discursos pedagógicos contemporáneos. Invocando el aprendizaje a lo largo de la vida, analizamos las incongruencias teórico-conceptuales de la “educación no formal”, del uso y abuso que de esta denominación hacen los organismos internacionales, las comunidades académicas y profesionales en distintos contextos. Además de diferenciarla de la educación escolarizada (formal), vacían las identidades de “otras educaciones”. Acontece con la educación popular y la social, ocultando sus motivaciones políticas e ideológicas tras la lógica de la división. Tan formal como la que más, su creciente reconocimiento en las Ciencias de la Educación se silencia en los textos más ortodoxos de la teoría de la educación, las declaraciones e informes gubernamentales. Por eso exigimos propuestas y respuestas alternativas para mejorar la educación y la sociedad.
Sweet Cherry Fruit Characteristic in Covered Orchards
Authors: Vávra Radek
Published: May 2020

The aim of evaluations performed in experimental plantings of the Research and Breeding Institute of Pomology Holovousy Ltd. was to verify the effect of covering systems on fruit characteristics – size, weight, firmness and soluble solids content (SSC). The research was focused on evaluation of fruit characteristics in 2017 and 2018 on fourteen cultivars: ´Amid´, ´Cristiana´, ´Early Korvik´, ´Elza´, ´Fabiola´, ´Felicita´, Horka´, ´Justyna´, ´Kasandra´, ´Kordia´, ´Korvik´, ´Tamara´, ´Těchlovan´ and ´Vanda´. The tested cultivars were grown in an IPM irrigated covered orchard. The largest fruit size was recorded for the cultivar ´Tamara‘ with 29.5 mm followed by the cultivar ´Horka‘ with 29 mm and ´Felicita´ with 28.6 mm. The greatest weight was recorded for the cultivar ´Tamara‘ with 12.4 g followed by ´Felicita´ with 12.3 g. The greatest firmness was recorded in fruits of the cultivar ´Amid´ with index 77.5 and ´Tamara´ with index 73.2. High correlation between fruit characteristics was found only between weight and size of fruits (correlation coefficient 0.88). High differences were recorded between years. In 2017, fruits characteristics were higher (size 27.5 mm, weight 10.9 g, firmness 65.3, SSC 19.3 °Brix) while in 2018, fruit characteristics were lower (size 26.5 mm, weight 9.2 g, firmness 59.2, SSC 16.5 °Brix).
Validation of friction factor predictions in vertical slurry flows with coarse particles
Authors: Bartosik Artur
Published: May 2020

The paper presents validation of a mathematical model describing the friction factor by comparing the predicted and measured results in a broad range of solid concentrations and mean particle diameters. Three different types of solids, surrounded by water as a carrier liquid, namely Canasphere, PVC, and Sand were used with solids density from 1045 to 2650 kg/m3, and in the range of solid concentrations by volume from 0.10 to 0.45. All solid particles were narrowly sized with mean particle diameters between 1.5 and 3.4 mm. It is presented that the model predicts the friction factor fairly well. The paper demonstrates that solid particle diameter plays a crucial role for the friction factor in a vertical slurry flow with coarse solid particles. The mathematical model is discussed in reference to damping of turbulence in such flows. As the friction factor is below the friction for water it is concluded that it is possible that the effect of damping of turbulence is included in the KB
function, which depends on the Reynolds number.
Controls on event runoff coefficients and recession coefficients for different runoff generation mechanisms identified by three regression methods
Authors: Chen Xiaofei , Parajka Juraj , Széles Borbála , Strauss Peter , Blöschl Günter
Published: May 2020

The event runoff coefficient (Rc) and the recession coefficient (tc) are of theoretical importance for understanding catchment response and of practical importance in hydrological design. We analyse 57 event periods in the period 2013 to 2015 in the 66 ha Austrian Hydrological Open Air Laboratory (HOAL), where the seven subcatchments are stratified by runoff generation types into wetlands, tile drainage and natural drainage. Three machine learning algorithms (Random forest (RF), Gradient Boost Decision Tree (GBDT) and Support vector machine (SVM)) are used to estimateRcandtcfrom 22 event based explanatory variables representing precipitation, soil moisture, groundwater level and season. The model performance of the SVM algorithm in estimatingRcandtcis generally higher than that of the other two methods, measured by the coefficient of determinationR2, and the performance forRcis higher than that fortc. The relative importance of the explanatory variables for the predictions, assessed by a heatmap, suggests thatRcof the tile drainage systems is more strongly controlled by the weather conditions than by the catchment state, while the opposite is true for natural drainage systems. Overall, model performance strongly depends on the runoff generation type.

Published: May 2020

A variety of magnetic fishing tools poses the task of the optimal choice of tool for eliminating accidents during the construction, operation and repair of wells. Existing criteria for assessing the quality of fishing magnets are characterized by the complexity of the determination and the ambiguity of the results. Therefore, the aim of research is development of a new approach to determining the technical level of fishing tools of various types and designs. A complex criterion has been developed that allows to evaluate the technical level of magnetic systems by correlating the actual and theoretical values of the total and specific lifting forces. Also it has been carried out a qualimetric analysis of magnetic tools, which are currently offered by world manufacturers. As a result, mathematical models are found that describe the average and modern world level of devices with specific lifting force. Technical decisions are proposed, the implementation of which in the design of magnetic systems of fishing tools will allow to achieve high values of lifting force. Application of the proposed complex criterion along with the results of qualimetric analysis will make it possible to objectively assess the technical level of magnetic fishing tools both at the design stage and during serial production.
Cognitive Technologies in the Management and Formation of Directions of the Priority Development of Industrial Enterprises
Authors: Kwilinski Aleksy , Kuzior Aleksandra
Published: May 2020

The possibilities of using cognitive technologies in the organization of systematic industrial enterprise management are described in the article. Strategic links are defined in the development of a system of stochastic models of enterprise management based on artificial intelligence. The possibility of introduction of the Perceptron model in the industrial enterprise management with the purpose of identification of “bottlenecks” in the functionality of business activity and improvement of procedures of decision-making in the framework of creation of the program of development and technical re-equipment of the enterprise is proven. The authors offered an organizational and economic mechanism of operation of an industrial enterprise, which includes new means of implementation of managerial actions through the use of a matrix of assessment of the level of implementation of cognitive technologies. The method of determining priority directions for the implementation of cognitive technologies at an enterprise was developed based on the results of the assessment of the depth of penetration of cognitive technologies and the result obtained from their implementation, which additionally takes into account the resource ratio of the implemented technologies defined as the ratio of estimates of the actual level of competencies to what is needed to work with new cognitive technologies, which allows to obtain the planned economic and organizational effect.
The prevalence of occult ovarian cancer in the series of 155 consequently operated high risk asymptomatic patients – Slovenian population based study
Authors: Gornjec Andreja , Merlo Sebastijan , Novakovic Srdjan , Stegel Vida , Gazic Barbara , Perhavec Andraz , Blatnik Ana , Krajc Mateja
Published: May 2020

Background

We assessed the prevalence, localization, type and outcome of occult cancer at risk-reducing salpingo-oophorectomy or salpingectomy (RRSO) in asymptomatic carriers of pathogenic or likely pathogenic BRCA1/2 variants and high-risk BRCA1/2 negative women.

Patients and methods

A retrospective analysis of all consecutive gynaecologic preventive surgeries from January 2009 to December 2015 was performed. Participants underwent genetic counselling and BRCA1/2 testing before the procedure. Data on clinical parameters, adjuvant treatment and follow-up were collected and analysed.

Results

One hundred and fifty-five RRSO were performed in 110 BRCA1, 35 BRCA2 carriers of pathogenic or likely pathogenic variants and 10 high-risk BRCA1/2 negative women, at the mean age of 48.3 years. Nine occult cancers (9/155, 5.8%) were identified; eight in BRCA1 positive women and one in high-risk BRCA1/2 negative woman. We identified four non-invasive serous intraepithelial tubal carcinomas (3 in BRCA1 carriers and 1 in a high-risk BRCA1/2 negative woman) and five invasive tubo-ovarian high grade serous cancers (all detected in BRCA1 carriers). Only one out of nine patients (11.1%) with occult cancer had a slightly elevated CA-125 value preoperatively.

Conclusions

A 5.8% prevalence of occult invasive and noninvasive tubo-ovarian serous cancer after RRSO was found in high risk asymptomatic and screen negative women. We conclude that RRSO should be performed in BRCA1/2 carriers and in high-risk BRCA1/2 negative women. Age of preventive gynaecologic surgery should be carefully planned, taking into account the completion of childbearing age and type of mutation. The results favour the tubal hypothesis of tubal origin of high grade serous ovarian and peritoneal cancer. Cytology result of peritoneal cavity washing was important for the decision making process in determining treatment. Cytology examination should be performed in all cases of RRSO. CA-125 assay did not prove to be an effective screening tool for early cancer detection in our patients.

Background

Management of non-small-cell lung cancer (NSCLC) is affected by regional specificities. The present study aimed at determining diagnostic and therapeutic procedures including outcome of patients with NSCLC stage III in the real-world setting in Central European countries to define areas for improvements
.

Patients and methods

This multicentre, prospective and non-interventional study collected data of patients with NSCLC stage III in a web-based registry and analysed them centrally.

Results

Between March 2014 and March 2017, patients (n=583) with the following characteristics were entered: 32% females, 7% never-smokers; ECOG performance status (PS) 0, 1, 2 and 3 in 25%, 58%, 12% and 5%, respectively; 21% prior weight loss; 53% squamous carcinoma, 38% adenocarcinoma; 10% EGFR mutations. Staging procedures included chest X-ray (97% of patients), chest CT (96%), PET-CT (27%), brain imaging (20%), bronchoscopy (89%), endobronchial ultrasound (EBUS) (13%) and CT-guided biopsy (9%). Stages IIIA/IIIB were diagnosed in 55%/45% of patients, respectively. N2/N3 nodes were diagnosed in 60%/23% and pathologically confirmed in 29% of patients. Most patients (56%) were treated by combined modalities. Surgery plus chemotherapy was administered to 20%, definitive chemoradiotherapy to 34%, chemotherapy only to 26%, radiotherapy only to 12% and best supportive care (BSC) to 5% of patients. Median survival and progression-free survival times were 16.8 (15.3;18.5) and 11.2 (10.2;12.2) months, respectively. Stage IIIA, female gender, no weight loss, pathological mediastinal lymph node verification, surgery and combined modality therapy were associated with longer survival.

Conclusions

The real-world study demonstrated a broad heterogeneity in the management o f stage III NSCLC in Central European countries and suggested to increase the rates of PET-CT imaging, brain imaging and invasive mediastinal staging.

Background

The aim of the study was to investigate the performance of the Liver Imaging Reporting and Data System (LI-RADS) v2018 for combined hepatocellular-cholangiocarcinoma (cHCC-CCA) identifying the features that allow an accurate characterization.

Patients and methods

Sixty-two patients (median age, 63 years; range, 38–80 years), with pre-surgical biopsy diagnosis of hepatocellular carcinoma (HCC) that underwent hepatic resection, comprised our retrospective study. All patients were subject to multidetector computed tomography (MDCT); 23 patients underwent to magnetic resonance (MR) study. The radiologist reported the presence of the HCC by using LIRADS v2018 assessing major and ancillary features.

Results

Final histological diagnosis was HCC for 51 patients and cHCC-CCA for 11 patients. The median nodule size was 46.0 mm (range 10–190 mm). For cHCC-CCA the median size was 33.5 mm (range 20–80 mm), for true HCC the median size was 47.5 mm (range 10–190 mm). According to LIRADS categories: 54 (87.1%) nodules as defined as LR-5, 1 (1.6%) as LR-3, and 7 (11.3%) as LR-M. Thirty-nine nodules (63%) showed hyper-enhancement in arterial phase; among them 4 were cHCC-CCA (36.4% of cHCC-CCA) and 35 (68.6%) true HCC. Forty-three nodules (69.3%) showed washout appearance; 6 cHCC-CCAs (54.5% of cHCC-CCA) and 37 true HCC (72.5%) had this feature. Only two cHCC-CCA patients (18.2% of cHCC-CCA) showed capsule appearance. Five cHCC-CCA (71.4% of cHCC-CCA) showed hyperintensity on T2-W sequences while two (28.6%) showed inhomogeneous signal in T2-W. All cHCC-CCA showed restricted diffusion. Seven cHCC-CCA patients showed a progressive contrast enhancement and satellite nodules.

Conclusions

The presence of satellite nodules, hyperintense signal on T2-W, restricted diffusion, the absence of capsule appearance in nodule that shows peripheral and progressive contrast enhancement are suggestive features of cHCC-CCA.

Bu çalışmada, eşek sütü, kazein ve kesik süt suyu proteininin in vitro ortamda antikanser ve yara iyileştirme potansiyelinin araştırılması amaçlanmıştır. Öncelikle eşek sütünün pH değeri değiştirilerek kazein ve kesik süt suyu proteinleri elde edilmiştir. Eşek sütü, kazein ve kesik süt suyu proteininin in vitro ortamda insan prostat kanseri hücre hattı (PC-3) üzerindeki antikanser aktivitesi MTT hücre proliferasyon testi kullanılarak incelenmiş olup antikanser aktivite bulunamamıştır. MTT denemelerinde özellikle kazein proteininin %140 hücre proliferasyonuna sebep olduğu gözlenmiştir. Bu doğrultuda, insan fibroblast hücre hattı (BJ) üzerinde çizik testi uygulanarak bu proteinlerin hücre migrasyonu ve yara iyileştirici etkileri incelenmiştir. Eşek sütü, kazein ve kesik süt suyu proteini (3200 µg/ml) kontrol grubuna kıyasla hücre migrasyonunda ve in vitro yara kapanma hızında anlamlı artışa sebep olmuştur. Bu çalışma ile eşek sütünün ve içerisindeki diğer proteinlerin in vitro ortamda antikanser aktivite göstermeyip hücre proliferasyonuna sebep olduğu ve yara iyileştirme amaçlı kullanılabileceği gösterilmiştir.

人际交往中的礼貌问题，一直是全球语用学领域研究的重要内容。目前，社交用语研究多关注言语交际中的真实礼貌或不礼貌现象，然而介于两者之间的一种连续体——虚假礼貌，作为一种特殊的语言现象，却未受到足够的重视。基于文献研究不难发现，现存虚假礼貌研究多着眼于研究其语用特征和实施策略，对其语用功能的研究相对欠缺。中国文化中存在大量的虚假礼貌现象，《红楼梦》作为中国传统文化的代表作，其中不少虚假礼貌现象非常值得大家深入探究。论文结合礼貌原则和面子理论，以中国四大名著之一《红楼梦》中的部分对白为语料，通过对人物经典对白分析，研究其中虚假礼貌的实现方式及语用功能。基于语料分析，论文尝试从语用学的角度探讨虚假礼貌，并尝试对现存虚假礼貌实现方式，以及语用功能做出补充。

Immunobiochemical parameters of maral blood in the Republic of Тuvа
Authors: Kuzmina E. E.
Published: May 2020

The results of the study of hematological and biochemical blood parameters of Altai-Sayan breed of marals are presented. Blood parameters of 5–6 year-old stag marals brought from the Altai Republic in 2014–2015 and currently bred in the Republic of Tuva were studied. Content of total protein in blood was lower than the established standard indicators for maral blood by 12.8%, albumin by 51.5, betaglobulin by 72.4, and cholesterol by 59.5%. The following indicators exceeded the standard: number of leukocytes – by 40.4%, alpha-globulins – by 21.0%, gamma-globulins – 2.1 times, AcAt – by 6.8%, glucose – by 16.4%. The average IgA content in the blood of the studied animals was 0.022 mg/ml, IgG – 0.039, IgM – 0.020 mg/ml. A weak negative correlation was found between the content of IgG and the number of leukocytes (r = –0.38), as well as an average positive correlation between the level of IgA and the concentration of urea in the blood (r = 0.47). In the study of the phagocytic system of stag marals of the Tuvan population, the values of phagocytic activity were established at the level of 25.4 ± 0.29, the phagocytic index – 4.33 ± 0.09, and the phagocytic number – 1.03 ± 0.03. The revealed interconnections of the hematological, biochemical and immunological parameters of blood of stag marals brought from the Altai Republic and kept in the Republic of Tuva differ both in strength and in direction. Average negative correlations amounted to 41.9% of the total, average positive – 38.7, high positive – 12.9, high negative – 6.5%. Differences in the morphological and immunobiochemical composition of the blood of marals bred in the conditions of the Republic of Tuva from standard indicators are the result of optimal adaptation to the living conditions.

The coronavirus disease (COVID-19) pandemic has caused tremendous pressure on hospital infrastructures such as emergency rooms (ER) and outpatient departments. To avoid malfunctioning of critical services because of large numbers of potentially infected patients seeking consultation, we established a COVID-19 rapid response infrastructure (CRRI), which instantly restored ER functionality. The CRRI was also used for testing of hospital personnel, provided epidemiological data and was a highly effective response to increasing numbers of suspected COVID-19 cases.

Mike Joshi (MJ) - IT Director of ABC Corp (ABC) just got done with a meeting with Bob – Executive Vice President of Global Field Operations and Assurance for ABC Corp. MJ was asked to improve the output of ABC Corp’s current workforce to stay competitive in the hyper competitive telecommunications sector using technology. Bob demanded that MJ figure out a way to improve efficiency in ABC’s staff as they needed to push for the 5G deployment as well as Intelligent Edge Network. MJ was already aware of the fact that T-Mobile, one of ABC Corp’s fiercest competitors, was gaining traction on them on network connectivity, customer satisfaction and plethora of services it was providing. T-Mobile was offering incentives to ABC Corp’s existing customer to leave ABC Corp and move their service.
5G was in the midst of deployment and could become a game changer in terms of mobile connectivity and data throughput. It was a necessity in the world of social media, where the majority of the world population had handheld devices. Bob knew he needed skilled technology workers as well as customer care to support this mobile technology. How would he achieve such a goal when he was faced with a trimmed workforce? Bob wanted to know how he could squeeze higher performance from his top performers in the company using technology. Could he drive someone to put in the hard work required with the implementation of 5G and supporting existing technology and services? Bob needed a leaner and much more agile workforce especially after the recent job restructuring at ABC Corp. Bob needed employees to keep moving the goal line for the performance metric when T-Mobile was able to win over some contracts with large corporations due to the output and quality of its workforce. T-Mobile was able to offer a faster time for implementation of network services and Bob knew in order to improve efficiency at ABC Corp he needed a cultural transformation inside the workforce.
MJ knew he did not have much time to come up with a presentable plan to management. Bob was wondering if IT can build and implement any solution to help with the cultural transformation he needed. Bob also had an idea that there was an efficiency problem with the ABC Corp’ task force, he knew he would need MJ to pull some reports and analyze them to make sure he could back up his gut instinct.
