Futuro de la educación e incertidumbre
Authors: Gallardo M. Sara
Published: April 2021

Uno de los sectores más impactados por la pandemia ha sido la educación, toda vez que el futuro inspirado en la tecnología de información llegó a la fuerza y tomó por sorpresa a maestros, estudiantes y al sistema completo, para cubrir entre virtualidad y alternancia el proceso educativo en el país. De ahí que la conectividad tenga una incidencia nunca vista para que niños, jóvenes y adultos pue[1]dan gozar de ese derecho.

Según las cifras del boletín trimestral del Ministerio TIC, correspondiente al tercer trimestre de 2020, los accesos fijos a Internet eran 7,67 millones, mientras los accesos móviles 30,4 millones, en una población que supera los 50 millones de habitantes. Para reflexionar sobre diferentes aspectos que rodean esta problemática fueron invitados: Eduardo Escallón Largacha, decano de la Facultad de Educación de la Universidad de Los Andes; Marcela Junguito Camacho, PhD., rectora del Gimnasio Femenino, Horacio Torres Sánchez, profesor emérito de la Universidad Nacional y Viviana Garzón Cardozo, directora de la unidad STEM MD, del Parque Científico de Innovación Social.

Deteksi Api pada Video dengan Gaussian Mixture Model Untuk Deteksi Gerakan Dan Segmentasi Warna Api Dalam Ruang Warna YCbCr
Authors: Adi Ristirianto , Suta Wijaya I Gede Pasek
Published: April 2021

Fire is a disaster that can endanger lives and cause property loss. The solution to detect fire that is commonly used today is to use a sensor. Fire sensors can be used together with surveillance cameras (CCTV) which are now being installed in many office buildings. This study tries to build a model for detecting fire in video with a digital image processing approach using the Gaussian Mixture Model for motion detection and fire color segmentation in the YCbCr color space. The model is then tested with metrics for accuracy, precision, recall, and processing speed. The dataset used is in the form of videos with small, medium, large fire sizes, and videos that only have fire-like objects. The test results show that the algorithm is able to detect fire when the size of the fire is not too small or the position of the fire is close enough to the camera. For videos with a resolution of 800x600 and a framerate of 30 fps, it can achieve 66.89% accuracy, 73.77% precision, and 66.66% recall. The performance during the day is relatively better than at night. Algorithm processing speed is too slow to be implemented in real-time

Authors: Liao Tung-Shan , Pham Thi Thuy Dung , Lu Juin-Cherng
Published: April 2021

The paper's purpose is to examine the role of knowledge and learning as a dynamic capability that leads to competitive advantage in family firms. It further conceptually develops a model showing the relationship between intellectual capital, firm performance, and dynamic capabilities in family firms. Using past case studies related to the subject, this study highlights the importance of knowledge accumulation, integration, codification, and the preservation of socioemotional wealth as dynamic capabilities that allow a family firm to sense and seize business opportunities that transform the business to a competitive advantage. Findings from the case applications reveal that family businesses benefit from the accumulation of knowledge through expertise, skills, and employment of non-family members and having family involvement as strategic important assets that lead to increased value in family firms’ performance.
The Root cause of the Anti-globalization Movement in the United States: the Erosion of the Level-standard Economy
Authors: Sun Keren
Published: April 2021

This paper uses Qian’s level-standard economy approach to analyze the losses and gains of American globalization in the Neoliberal Era. Analysis found that: level-standard economy’s sectors are the losers during the process of American globalization in the Neoliberal Era; and super level-standard economy’s sectors are the winners during the process of American globalization in the Neoliberal Era. The erosion of the level-standard economy has great harm and impact on related parties, so that the USA emerges the movement of populist backlash against globalization. This paper proposes 4 measures to solve this dilemma, i.e., to impose higher tax rates on the winners of American globalization in the Neoliberal Era, to subsidize more to the losers of American globalization in the Neoliberal Era, to moderately relocate manufacturing and other industries back to the U.S., and to further strengthen transnational cooperation.

Authors: YULUĞ Burak , ASLAN Ahmet
Published: April 2021

The human brain is interconnected in a plastic manner to form functional brain net-works. This dynamic and flexible neuronal reorganization process is essential for an efficient regeneration process in the central nervous system, especially when it comes to memory, learning, and posttraumatic conditions. Here, we tried to define basic principles and the mechanisms underlying neuroplasticity process in the brain which serve as an important template for future studies on neurorehabilitation in neu-rodegenerative diseases, such as stroke, Alzheimer’s Disease and traumatic brain injury.

Ruy Duarte de Carvalho’s Neo-Animist Project: An African Approach to Posthumanism
Authors: Girotto Alice
Published: April 2021

The literary project of the Angolan writer Ruy Duarte de Carvalho, from the collection of poems Chão de oferta (1972) to the metafictional trilogy Os filhos de Próspero (2009), along with his work as an anthropologist, filmmaker and intellectual, is animated by a research for a conjunction between subject, geology, landscape and politics, which rejects Western epistemological categories and their underlying powers. At the end of his life, this trait of his personality and work took the form of an unfinished neo-animist project, based on a decalogue in which he criticises the humanist paradigm for the sake of recovering an “equilibrium politics” relying on “[o]ther paradigms set aside and hidden from consideration because they originate in cultures dominated or annihilated by the Western world”. The aim of this essay is both to trace the origins of Carvalho’s neo-animist project in his early poetry and narrative and connect it with a broader African criticism, both literary and philosophical, in order to include his thought within the African approach to posthumanism.
Sur les pas de Louis-Philippe Dalembert. Un hommage à la carrière du « gavroche caraïbe »
Authors: Boraso Silvia
Published: April 2021

In 1982, the Haitian writer Louis-Philippe Dalembert published his first collection of poetry, Évangile pour les miens. It was the beginning of a prolific, multiform, and successful career. During the next thirty years, he has published four other poetry collections, four collections of short stories, ten novels, and numerous essays. Intended as a tribute to Dalembert’s literary work, this article will try to describe the evolution of his production in verse and prose. In particular, three recurrent themes will be discussed: 1) the elaboration in his first texts of a system of rememorating strategies that will lead to the formulation of the notion of ‘pays-temps’; 2) the use of an urban setting, namely the borough, to convey the collective values of the community; 3) the birth, in his late publications, of a universal poetics transcending any type of border.
Language Colonization and English Hybridization: The Use of Irish English Lexis in Twentieth Century Irish Drama
Authors: Luppi Fabio
Published: April 2021

Irish English, albeit a variant of the language of the colonizer, can be considered an important identitarian element in twentieth century Irish literature. By taking into account Irish English terms in a selection of Anglo-Irish plays (with particular focus on the titles), this paper examines the lexical choices that contribute to rendering cultural, geographical and political meanings – some of which are derogatory, patronizing and pejorative. The conclusion, with reference to Brian Friel’s Translations, reflects on the implications of the dominance of English in Ireland following its replacement of Irish Gaelic. The various loanwords and calques from Irish Gaelic found in these plays thus acquire a cultural and political significance that is specific to the Irish context.
Langue française et arts du spectacle à Montréal : aperçu de deux parcours biographiques
Authors: Brancaglion Cristina
Published: April 2021

In 2018 the biographies of two women who have shaped and animated the city's theatrical life since the 1930s were published in Montréal: one, Madame Jean-Louis Audet, dedicating herself to the training of actors through her diction courses, the other, Monique Miller, playing key roles in the Montreal and the international theatre scene. The paths of the two women are outlined in two volumes –  signed respectively by Muriel Gold and Pierre Audet –  rich in iconographic documents that allow to relive some important episodes of Québec's sociolinguistic and cultural history. The aim of this contribution is to highlight how the two writings can be useful sources for the study of some of the changes that marked the advent of the ‘Révolution tranquille’: the first signs of women's emancipation, the emergence of Québec's cultural production, the advent of television and its correlations with the other performing arts (theater, radio, cinema), the role of some actors in Québec's linguistic, ideological and artistic evolution

PROSPECTIVE DIRECTIONS OF CHANGES IN THE FINANCIAL REPORTING OF ENTERPRISES IN THE CONTEXT OF THE GLOBALIZATION OF THE WORLD ECONOMY
Authors: Dovbush Vita , Kozhushko Roman
Published: April 2021

Statement of the problem and tasks. Ukraine is a country with transitive economy characterized by creation and development of market institutions aimed at privatization of state property, deregulation and liberalization of economic relations. Transformation of economy of Ukraine requires from enterprises the application of management concepts, focused on the new conditions of economic management – uncertainty and crisis nature of market environment. The effectiveness of the implementation of new principles of management depends on the completeness and reliability of the information and analytical support of management decisions.Methods. The study used: a dialectical method, system analysis – for detailing and decomposition of the object of research into separate important constituent elements; synthesis – to summarize the various aspects of the financial statements of the enterprise.Results. The technical issues of accounting were investigated: the key differences in approaches to enterprise accounting between the International Financial Reporting Standards (IFRS), Generally Accepted Accounting Principles (US GAAP) and the Regulations (Standards) of Accounting (NARS) were determined; the impact of the identified differences on the data processing in the accounting systems was assessed. It is determined that governmental accounting rules in the United States are governed by its generally accepted GAAP accounting principles. It has been proven that conceptually, IFRS, which is used by states around the world, is more "principled" than GAAP, making it somewhat less complex and consistent, offering fewer exceptions and unique applications.Conclusions. The current trend in financial reporting is to produce integrated reports that combine financial and non-financial information. However, not all companies find it necessary to disclose more information than the amount required of them by regulators. Therefore, there is a need to standardize not only financial information, but also non-financial indicators and the very structure of an integrated report.

Authors: Laponoh Danyil V.
Published: April 2021

Background and objectives. Public-private partnership (PPP) is one of the most popular forms of cooperation between the state and business in the world. For Ukraine, PPP is one of the most promising ways to attract investment in the existing state and municipal infrastructure. The Law of Ukraine "On Public-Private Partnership" (2010) allows the implementation of projects in the format of the classic PPP. Most projects involved the development of infrastructure facilities and mining, which is typical for this kind of cooperation between the state and businessMethods. The study used: expert, statistical, comparative, scenario analysis; analysis of empirical data using methods of grouping, generalization, classification methods.Findings. The components of PPP relations are defined, the criteria for the classification of its forms, the essence and economic content of the category "public-private partnership", the features of public-private partnership in the market of road transport services in Ukraine are substantiated. The qualitative analysis of 111 concession projects has allowed to reveal the regularity and to present the variant of possible combination of experts' indications at certain parameters. Mean values and standard deviations of the expert testimonies were determined and distributions of the obtained data array of 111 concession PPP projects were constructed. The definition of the "quality" of expert assessments and evaluation of the effectiveness of 111 PPP projects for the provision of road transport services is formed.Conclusion. The components for public-private partnership in the market of road transport services have been defined: PPP implies a contractual form (agreements, contracts, etc.), in which the rights and obligations of each party are clearly defined; implementation of projects in the market of road transport services implies mutual economic benefit for all project participants through the best interaction, focused on better results for lower cost; public-private partnership is characterized by increased.

Published: April 2021

Introduction. Research and analysis of the theoretical foundations allowed to determine the relationship between scientific and technological progress, innovation processes in the economy. The dominant role in economic development is played by scientific and technological progress, the core of which is innovation. The variety of types, forms and definitions of innovations necessitates the study of the essence of innovative development of agricultural enterprises, their main features and role in a market economy.The hypothesis of the research is to substantiate the recommendations and proposals for improving the efficiency of innovation of agricultural enterprises as a priority sector, taking into account the European integration vector of the state.The purpose of the study is to substantiate the peculiarities of the influence of the market environment on the innovative development of agricultural enterprises.The methodology of scientific research is general and special research methods: dialectical – for analysis and understanding of the essence and content of the categorical series "innovation", "innovation process", monographic – in highlighting the views of scientists on the research issues; strategic   analysis – to determine the priority areas for intensifying the innovative development of agricultural enterprises.Conclusions and prospects for further research. Based on the concept of growth cycles, it can be concluded that in a market environment, the organization of innovation is associated with the division and cooperation of labor, providing the necessary resources, selection and implementation of procedures for effective implementation of the innovation cycle. Therefore, the peculiarities of the influence of the market environment on the innovative development of agricultural enterprises, in our opinion, should be considered in terms of innovation systems. Factors that create a favorable market environment that allows the surveyed enterprises to be able to make significant upgrades, determine the four attributes of the country: the conditions for the factors; state of demand; related and supporting industries; stable strategy and structure. They each and all together form the basis of the country's competitive advantages, the space that each state creates and maintains for its industries.

Published: April 2021

It is advisable that the medical history of the gynecologist be extended to include the functioning of patients in the sexual sphere, including partner relationships, which affects health, including women’s sexual health. For many patients, sexology issues are taboo and autosexual behavior (masturbation) is a special taboo. Masturbation refers to sexual stimulation, especially of one’s own genitals and often to the point of orgasm, which is performed manually, by other types of bodily contact (except for sexual intercourse), by use of objects or tools, or by some combination of these methods. Autosexual behavior as a topic for inclusion in general gynecology and developmental gynecology indicates the need for a very individual approach to this issue in the context of a given patient. Similar medical issues seem to refer to a general truth about medicine that it is neither merely art nor science, in the modern sense of these terms. It is a separate, indirect field, tertium quid, i.e., the third, intermediate possibility between art and science, but different from both. In the Aristotelian sense, medicine is a habit of practical understanding, perfected by experience in patient care, and the issue of autosexual behavior in general gynecological requires special experience and an individual approach to a patient.
Should diagnostic hysteroscopy be performed routinely following thermal balloon endometrial ablation? A case report of thermal bowel injury and literature review
Authors: Al-Mandeel Hazem
Published: April 2021

Although thermal balloon endometrial ablation (TBEA) is an effective and easy technique, it can cause serious complications, including bowel injury, if perforation occurs. In this paper, a case of thermal bowel injury caused by the Thermablate Endometrial Ablation System is presented with a review of previous literature on such complications. Based on this case and expert recommendations, users are advised to follow established protocols, including hysteroscopy just prior to the insertion of the TBEA catheter to exclude prior uterine perforation from the uterine sound or curettage, and an additional hysteroscopy after completion of the ablation as the final step to ensure that a perforation has not occurred.

Published: April 2021

Placental mesenchymal dysplasia (PMD) is a rare disorder of the placenta characterized by placentomegaly with diffuse hydropic stem villous, aneurysmally dilated vessels, and lack of trophoblastic proliferation. Case: The prenatal ultrasound of a 34-year-old woman (G1P0) at 33 weeks of gestation showed an enlarged placenta with multiple cystic lesions, heterogeneous echoes with no active blood flow, and fetal growth restriction (FGR). The differential diagnosis involved partial mole, placental hemorrhage, and PMD. She developed preeclampsia at 38 weeks of gestation and gave birth to a normally formed, growth-restricted baby. The placenta, weighing 785 g, showed scattered cystic vesicles in the parenchyma. The histology shows enlarged edematous stem villi with occasional cistern formation and no area of chorioangioma or features of molar pregnancy. PMD associated fetal growth restriction was diagnosed. Conclusion: PMD has prenatal ultrasound result resembling those of partial mole, placental hemorrhage and chorioangioma, but the fetus is phenotypically normal. Nevertheless, fetal surveillance is essential.

Published: April 2021

This study was aimed to investigate the effect of vitamin E (Vit E) supplementation on endometrial thickness and pregnancy outcomes in infertile women. The literature was screened by two researchers and the data was extracted by searching published literature from 1999 to 2020 in the Cochrane library, PubMed, and Embase database. Seven clinical trials were included, with a total of 652 subjects. Here we found the mean endometrium was thicker in Vit E treatment group than that in the control group [SMD = 0.57, 95% CI (0.26, 0.87), P = 0.0002]. Subgroup analysis showed that no significant effect between administration of 400 IU (267 mg) or 100 mg Vit E per day. There was no significant difference between with or without Vit E on ongoing pregnancy rate [OR = 1.08, 95% CI (0.72, 1.62), P = 0.70]. The current evidence demonstrates that Vit E supplementation may increase endometrial thickness in women of reproductive age.

Published: April 2021

Background: Carcinosarcoma is a rare malignancy of the female reproductive system, consisting of carcinomatous and sarcomatous components. It originates from the paramesonephric and mesonephric duct residues and is also called malignant mixed Mullerian tumor. Case Presentation: A 58-year-old post-menopausal woman, gravida 2, parity 2, who had no known diseases and no previous surgery presented to another clinic with pelvic pain that had been persisting for about a year and vaginal bleeding for the past month. There was continuous bleeding that was not associated with coitus, and cervical biopsy was reported as carcinosarcoma of heterologous type (the epithelial part was serous carcinoma and the mesenchymal part was chondrosarcoma); the patient was referred to our clinic and underwent evaluation. Conclusion: Effective follow-up is very important considering the aggressive clinical picture of carcinosarcoma cases. It should be kept in mind that metastasis may occur, especially in cases with hypercalcemia and deterioration of the general condition.

Published: April 2021

This study aims to provide the cerebellar extrauterine reference value related to gestational age by analysing the neonatal cerebellum development with different gestational age, by means of cranial ultrasound. A total of 376 eligible cranial ultrasound images of neonates with gestational age of 25 to 41 weeks were selected. Transverse cerebellar diameter, vermis height, vermis diameter, vermis circumference, vermis area and vermis eccentricity ratio were measured and followed by statistical analysis. Transverse cerebellar diameter formed a linear equation with the gestational age, which was Y = 0.104X + 0.176, R2 = 0.735 (P < 0.001). Vermis height formed a linear equation with the gestational age, which was Y = 0.069X - 0.328, R2 = 0.825 (P < 0.001). Vermis diameter formed a linear equation with the gestational age, which was Y = 0.051X - 0.604, R2 = 0.749 (P < 0.001). Vermis circumference formed a linear equation with the gestational age, which was Y = 0.284X - 1.709, R2 = 0.788 (P < 0.001). Vermis area formed a linear equation with the gestational age, which was Y = 0.227X - 4.445, R2 = 0.82 (P < 0.001). Vermis eccentricity ratio formed a linear equation with the gestational age, which was Y = -0.01X + 0.909, R2 = 0.142 (P < 0.001). The positive correlation between vermis height and gestational age was the strongest (r = 0.908, P < 0.001). The results provided that the cerebellar extrauterine reference range, between transverse cerebellar diameter, vermis height, vermis diameter, vermis circumference, vermis area, vermis eccentricity ratio of neonates of appropriate for gestational age. Gestational age is helpful for clinical diagnosis and evaluation of cerebellum growth and development of newborns.
Matrix metalloproteinase 9 gene promoter region -1562 C/T single nucleotide polymorphism increases the susceptibility to hypertensive disorders of pregnancy: a meta-analysis
Authors: Zhou Yi , Wang Ran , Chen Shi-Xian , Wu Li-Sheng , Zhu Jun-Qing
Published: April 2021

Hypertensive disorders of pregnancy (HDP) encompass a group of diseases. Single nucleotide polymorphisms (SNPs) are common in the matrix metalloproteinase 9 (MMP9) genes. The objective of this study was to analyse whether genetic polymorphisms in MMP9-1562 C/T alter the risk of HDP. Studies published up to October 2019 across PubMed, ScienceDirect, SpringerLink, and China National Knowledge Infrastructure database were searched. Case-control or cohort studies involving subtypes of HDP and distribution of genotypes and/or alleles within MMP9-1562 C/T in both patients and controls were selected. Number of genotypes and/or alleles for MMP9-1562 C/T polymorphisms were obtained and analyzed using Stata software. Eight published reports including 1300 HDP patients and 1612 controls were included in the meta-analysis. Results showed that a variant genotype and allele of MMP9-1562 C/T increased the risk of HDP, with pooled OR 1.50 (95% CI 1.16–1.95, P = 0.002) and 1.36 (95% CI 1.15–1.61, P < 0.001). Subgroup analyses showed that the variant genotype and allele of MMP9-1562 C/T also had increased risk of preeclampsia (OR = 1.48, 1.32; 95% CI 1.18–1.86, 1.08–1.62; P = 0.001, 0.007) and gestational hypertension (OR = 2.23, 1.88; 95% CI 1.52–3.28, 1.33–2.65; P < 0.001, < 0.001) in the fixed-effects models. This suggests that variant genotype (TT + TC) and allele (T) of MMP9-1562 C/T are associated with susceptibility of HDP, especially preeclampsia and gestational hypertension.
Routine blood tests in early pregnancy: their development and value in the early diagnosis of gestational diabetes mellitus
Authors: Liu Guo-Lin , Zhang Ning-Zhi
Published: April 2021

With the change in China’s second-child fertility policy, the numbers of older pregnant women and high-risk pregnancies have significantly increased, and the incidence of gestational diabetes mellitus (GDM) is likely to rise. GDM can cause a variety of adverse pregnancy outcomes, seriously threaten the safety of perinatal mothers and infants, and affect the long-term health of mothers and their offspring. Currently, the GDM screening period is between 24 to 28 weeks of pregnancy, but there are some shortcomings in screening at this time, since because of late diagnosis, the best time for intervention and treatment for some high-risk pregnant women may be delayed. Studies have shown that early prediction and early diagnosis of GDM is of great significance to improve pregnancy outcomes, so it is important to investigate early pregnancy prediction indexes of GDM to improve the screening efficiency for GDM and improve the management of GDM. It has been found that blood cell parameters, inflammatory factors, fat metabolism indices and liver enzyme metabolism markers have specific early predictive value for GDM. The application of these parameters combined with significant independent risk factors in the early prediction and early diagnosis of GDM will be of great value in the prevention and treatment of GDM and the prognosis of mothers and infants. This article reviews the development of routine blood test parameters during pregnancy and their value in the early diagnosis of GDM.

Published: April 2021

Objective: To investigate associations of the time interval between hCG administration and oocyte pick up with oocyte maturation, embryonic morphology, morphokinetics, and IVF outcome, in different age groups. Design: A retrospective cohort study. Setting: An academic medical center. Patients: Women who underwent IVF and ICSI cycles in which all oocytes were incubated in a time lapse microscopy system (EmbryoScope). Cycles were stratified by age and time from hCG exposure. Interventions: None. Main Outcome Measures: Of 2185 IVF/ICSI OPU cycles, 820 cycles were included in the analysis. Final analysis was made on 796 cycles (4930 oocytes). Oocyte number and their maturity, fertilization rates, and embryo quality defined by morphology and morphokinetics, clinical pregnancy, and live birth rates. Results: The median hCG-oocyte pick up (OPU) interval was 34.45 hours. Among women over age 36 years, longer intervals were associated with both a higher fraction of mature oocytes (P < 0.008) and better morphology grading of embryos (P < 0.01). At all ages and all intervals, those with cleavage time, t2 ≤ 27 hours achieved a statistically significant higher clinical pregnancy rate. No differences were found in morphokinetics (t2) between different hCG-OPU intervals for any of the age groups. Conclusions: Extending hCG to OPU interval may be beneficial for patients aged > 36 years, as more mature eggs and better embryo morphology were achieved. In older women with fewer oocytes retrieved, even a small extra number of mature oocytes may prove crucial for treatment outcome and improve success rates. A prospective, randomized study is warranted to determine whether optimal hGC-retrieval time interval merits revision/adjustment for older women.

Authors: Ko Hyun Jin , Hong Seong Yeon , Bae Jin Young
Published: April 2021

It is known that atosiban has fewer side effects than conventional tocolytics. In clinical practice, however, hyperglycemia can be commonly observed in mothers who have been administered atosiban. Therefore, we investigated whether intravenous atosiban injection actually causes hyperglycemia and how these changes affect newborns. From December 2015 to July 2018, a retrospective study was conducted on 96 mothers who were diagnosed with preterm labor and were administered atosiban at our institution. Maternal blood glucose was measured and compared before and during the administration of atosiban. The paired t-test, independent samples t-test, Chi-square test and Fisher’s exact test were performed using SPSS version 21.0. A statistically significant increase in fasting blood glucose levels was observed during the administration of atosiban, compared with random blood glucose levels before administration (110.7 mg/dL vs. 86.3 mg/dL). The mean postprandial blood glucose level during administration was 170.75 mg/dL. Gestational diabetes, twin pregnancy, preeclampsia, and polyhydramnios did not significantly affect the degree of blood glucose increase. Statistically significant hypoglycemia was observed after performing a neonatal blood test immediately after birth from mothers who used atosiban. The neonates from the group with elevated maternal blood glucose levels exceeding 20 mg/dL showed lower blood glucose levels. No serious side effects other than hypoglycemia were observed. Atosiban administration in pregnant women results in significantly elevated maternal blood glucose, which results in hypoglycemia in neonates after birth. Therefore, neonates from mothers who received atosiban require a blood glucose test and close monitoring after birth.

Objective: The purpose of this study was to investigate the role of fibulin-5 in the transforming growth factor beta (TGF-β)/Smad signaling pathway by measuring the differential expression of fibulin-5, TGF-β, and Smad2/3 in the connective tissue of the vaginal anterior wall of Uyghur women with pelvic organ prolapse (POP). Methods: Thirty-six Uyghur patients diagnosed with POP, who were admitted to the First Affiliated Hospital of Xinjiang Medical University from March 2015 to June 2018, were enrolled in the study. In the same period, 15 patients with benign uterine hysterectomy were included in the control group. The relative protein expression levels of fibulin-5, Smad2/3, TGF-β1, TGF-βRI, and TGF-βRII in the anterior vaginal wall of each group were determined by immunohistochemistry, quantitative PCR, and Western blotting. Results: Immunohistochemistry showed that the expression levels of Smad2/3, fibulin-5, TGF-β1, TGF-βRI, and TGF-βRII were significantly lower in the POP group than in the control group (P < 0.05). RT-PCR showed that the mRNA expression levels of TGF-β1, TGF-βRI, TGF-βRII, and fibulin-5 were significantly lower in the POP group, with statistical significance (P < 0.05), whereas the expression of Smad2 and Smad3 decreased, but without statistical significance (P > 0.05). Western blot analysis showed that the expression of TGF-β1, TGF-βRI, TGF-βRII, fibulin-5, and phosphorylated Smad2/3 was significantly lower in the POP group than in the control group (P < 0.05), but there was no difference in Smad2/3 protein expression compared with the control (P > 0.05). Conclusion: The amount of functional elastic fibers in the pelvic connective tissue structure of POP patients decreased via involvement of the TGF-β/Smad signaling pathway. Future studies are needed to confirm the pathogenesis of POP.

Purpose of investigation: Current infertility treatment strategies may result in ovarian hyperstimulation syndrome (OHSS), which can present with hemodynamic instability that involves hemoconcentration, hypoxia, and liver and renal dysfunction that may result from thrombosis. This study’s purpose was to measure the serum biochemical oxidative stress markers in women with severe OHSS. Material and methods: For this prospective controlled study, serum levels of ischemia modified albumin (IMA), total antioxidant capacity (TAC), total oxidative capacity (TOS), oxidative stress capacity (OSI), and serum malondialdehyde (MDA) were measured in women with (n = 25) and without (n = 27) OHSS. Results: In our study, we observed significant differences between the two groups in terms of IMA, TAC, TOS, OSI, and MDA levels. High oxidative stress parameter levels in the OHSS group may indicate that OHSS is an oxidative stress condition. A bivariate correlation analysis revealed a significant correlation between serum TOS level, OSI ratio, and embryo or oocyte quality scores. In addition, there was a negative, non-significant tendency among OHSS patients regarding high IMA, OSI, TOS, and MDA levels and low oocyte and embryo scores. Pregnancy results were not affected in a statistically significantly manner. Conclusion: These results might indicate that oxidative stress status and oxygen radicals may negatively affect ART cycle outcomes.
An investigation into “Affect”, “Judgement” and
“Appreciation” in english speeches by nobel peace prize laureates
Authors: Pham Nguyen Thi Quynh Hoa, Nguyen Thi Phuong Thao
Published: April 2021

Appraisal Theory, which has been developed by linguists Martin & White since the 1990s, is the development of functional grammar in terms of interpersonal meaning. Based on the Appraisal Theory, this article aims to investigate the three sub-categories namely “Affect”, “Judgement” and “Appreciation” in English Speeches by Nobel Peace Prize Laureates (ESNPLs) with focus placed on identifying and describing syntactic realizations and semantic features of the three above-mentioned sub-categories in 25 ESNPLs collected from the official website of the Nobel Prize in the period 2000-2019. With regard to the syntactic aspect, the sub-categories can be realized by means of various groups in which Nominal Groups, Verbal Groups and Adjectival Groups are more noticeable. In terms of the semantic aspect, the research results show that both positive and negative values were demonstrated in the above speeches; however, positive values proved to be dominant.
Adaptive force/ position control for dual-arm system based on neural network radial basis function without using a force sensor
Authors: Pham Luu Thi Hue, Duong Minh Duc, Pham Thuc Anh Nguyen
Published: April 2021

The paper has developed an adaptive algorithm using neural network for controlling dual-arm robotic system in stable holding a rectangle object and moving it to track the desired trajectories. Firstly, an overall dynamic of the system including the dual-arm robot and the object is derived based on Euler-Lagrangian principle. Then based on the dynamics, a controller has proposed to achieve the desired trajectories of the holding object. A radial basis neural network has been applied to compensate uncertainties of system parameters. The adaptive learning algorithm has been derived owning to Lyapunov stability principle to guarantee asymptotical convergence of the closed loop system. Besides, force control at contact point is implemented without the measurements of forces and moments at contact points. Finally, simulation work on Matlab has been carried out to confirm the accuracy and the effectiveness of the proposed controller.

Published: April 2021

Secara logik, setiap usaha pengembangan profesi (professionalization) harus bertolak dari konstruk profesi, untuk kemudian bergerak ke arah substansi spesifik bidangnya. Diletakkan dalam konteks pengembangan profesionalisme keguruan, maka setiap pembahasan konstruk profesi harus diikuti dengan penemukenalan muatan spesifik bidang keguruan. Lebih khusus lagi, penemukenalan muatan didasarkan pada khalayak sasaran profesi tersebut. Profesional adalah pekerjaan atau kegiatan yang dilakukan oleh seseorang dan menjadi sumber penghasilan kehidupan yang memerlukan keahlian, kemahiran, atau kecakapan yang memenuhi standar mutu atau norma tertentu serta memerlukan pendidikan profesi. Tak diragukan, guru merupakan pekerjaan dan sudah menjadi sumber penghasilan bagi begitu banyak orang, serta memerlukan keahlian berstandar mutu atau norma tertentu. Kompetensi guru meliputi kompetensi pedagogik, kompetensi kepribadian, kompetensi sosial, dan kompetensi profesional yang diperoleh melalui pendidikan profesi. Kompetensi pedagogik menunjuk pada kemampuan mengelola pembelajaran peserta didik. Kompetensi kepribadian menunjuk pada kemampuan kepribadian yang mantap, berakhlak mulia, arif, dan berwibawa serta menjadi teladan peserta didik. Kompetensi profesional menunjuk pada kemampuan penguasaan materi pelajaran secara luas dan mendalam. Kompetensi sosial menunjuk kemampuan guru untuk berkomunikasi dan berinteraksi secara efektif dan efisien dengan peserta didik, sesama guru, orangtua/wali peserta didik, dan masyarakat sekitar.

Untuk dapat menjalankan suatu pekerjaan secara Profesional atau memiliki profesionalisme,sudah barang tentu diperlukan seperangkat pengetahuan, Sikap,dan keterampilan tertentu.seperti dijelaskan dalam prinsip diatas,bahwa profesionalisme bukan hanya soal pengetahuan, melainkan juga sikap dan keterampilan,maka konsep Kompetensi adalah terminologi yang tepat untuk menjelaskan komponen ini. Kompetensi secara sederhana dapat diartikan sebagai paket kemampuat yang menunjukkan perpaduan antara pengetahuan,sikap,dan keterampilan dalam suatu bidang.tiga aspek tersebut merupakan satu kesatuan yang membentuk kompetensi, sehingga seorang dapat dikatakan kompeten apabila menunjukkan penguasaan. Berkaitan dengan definisi kompetensi dan profesionalisme,setiap individu yang menjalankan profesi wajib memiliki kompetensi sesuai dengan profesinya.Profesi guru dalam undang- undang No.14 tahun 2005 tentang guru dan dosen menggariskan Kompetensi pokok yang harus dimiliki guru. Kompetensi tersebut adalah; Kompetensi profesional, Kompetensi pedagogik, kompetensi sosial,dan kompetensi kepribadian.Karena guru adalah individu yang memiliki tanggung jawab moral terhadap kesuksesan anak didik yang berada dibawah pengawasannya, maka keberhasilan siswa akan sangat dipengaruhi oleh kinerja yang dimiliki seorang guru. Oleh karena itu, kompetensi profesional diharapkan akan memberikan sesuatu yang positif yang berkenaan dengan keberhasilan prestasi belajar siswa.
