Authors: Brunheroto Paulo Henrique , Tomanek Dagmar Piotr , Deschamps Fernando
Published: March 2021

Goal: The present paper aims to investigate what are the main implications of Industry 4.0 technologies for production management.

Design / Methodology / Approach: The study was carried out through a survey with companies of the metal-mechanic and automotive industry of the Curitiba Metropolitan Region (Brazil) and of the Upper Bavaria Region (Germany) in order to determine the overall implementation level of technologies commonly associated with Industry 4.0 and their respective impacts to operations performance objectives.

Results: The results reveal that the overall implementation and improvement levels of the Industry 4.0 technologies is higher in Germany than in Brazil. Regarding the technologies, the Internet of Things presented one of the highest overall improvement levels for both regions, showing that the adoption of these technology could bring significant improvements for all performance objectives.

Limitations of the investigation: The results obtained with the present research refer only to the scenario of Curitiba and Metropolitan Region and the Upper Bavaria Region, more specifically from the companies of the metal-mechanic and automotive sectors and may differ from other sectors or regions.

Practical implications: From this research, companies that are willing to invest in new technologies can find a starting point to understand the benefits that they can possibly achieve based on results obtained from companies that have already adopted the technologies in Brazil and Germany.

Originality / Value: Studies that formally discuss the implications of the Industry 4.0 technologies for production management are lacking. Most studies focus excessively on the technologies without approaching their impact on management systems.

The article presents multifaceted considerations and results of analyses concerning the necessity to perceive the phenomenon of corruption through the prism of a gross violation of constitutional values, the principles of the rule of law and social justice. The main focus is on discussing civic rights that are effectively eradicated by corruption, at the same time emphasizing a holistic and systemic approach to understanding and interpreting specific processes and decisions confirmed in practice. At the beginning, it is explained why a broad research perspective should be adopted to understand the essence of corruption. An important argument supporting the correctness of the adopted approach are statements contained in the Government Program for Counteracting Corruption 2018–2020. Next, the most important constitutional values and civil rights are indicated, which are not respected and remain only in the declarative sphere as a result of corrupt practices. In order to prove the illusory nature and facade of certain provisions of the Polish Constitution, important statements contained in the judgments of the Constitutional Tribunal are quoted, and then these interpretations are analyzed in relation to real situations occurring in everyday reality. These problem issues are presented from the perspective of the constitutional principle of equality before the law, social justice and non discrimination. It is also noted in this regard that corruption activities are precisely the main factor leading to the division of citizens into two separate categories according to the way they are treated. Finally, it is mentioned that in the European Union ever greater emphasis is currently being placed on compliance with the rule of law. This problem is closely related to the need to understand the negative consequences of corruption as an element that undermines trust in the state, constitutional order and the rule of law.

Published: March 2021

A health resort treatment facility is a particular medical entity that performs therapeutic activities because it is located in a health spa resort municipality which has the status of a spa health resort. Only the spa health resort municipality implements its own tasks related to the maintenance of health spa functions, and creates the conditions for this type of health facility to function and to develop the municipal infrastructure in order to meet the needs of people staying in the municipality for spa resort treatment. The basic, but not the sole, purpose of establishing and maintaining a health resort treatment facility is medical activity consisting in providing spa patients with health services performed as part of spa treatment integrated into the health care system. The study focuses on how the definition of this type of facility has evolved in the legislation and the directions of changes that have occurred as a consequence of the change in the legal status, as well as other important terms referring directly to the spa treatment facility. The presentation of its various types and tasks performed by these establishments enables the identification of numerous interpretation problems related to their qualification. Due to the diversified ownership structure of these medical entities, reference is made to their organizational and legal forms, with a demonstration of the possible consequences that result from transforming these establishments into health resort companies. The current epidemic in Poland allows the scope of limitations in the operation of spa treatment facilities to be shown and, consequently, changes in the organization of some types of these facilities.
PATRO children, a multi-center, non-interventional study of the safety and effectiveness of Omnitrope® (somatropin) treatment in children: update on the United States cohort
Authors: Backeljauw Philippe , Miller Bradley S. , Levy Richard , McCormick Kenneth , Zouater Hichem , Zabransky Markus , Campbell Kim
Published: March 2021

Objectives

Omnitrope® (somatropin, Sandoz Inc.) is one of several recombinant human growth hormones (rhGH) approved in the United States (US) for use in pediatric indications, including growth hormone deficiency (GHD) and idiopathic short stature (ISS). We report data on the effectiveness and safety of Omnitrope® in the US cohort of the PATRO Children (international, longitudinal, non-interventional) study.

Methods

All visits and assessments are carried out according to routine clinical practice, and doses of Omnitrope® are given according to country-specific prescribing information.

Results

By September 2018, 294 US patients were recruited; the two largest groups were GHD (n=193) and ISS (n=62). Across all indications, HSDS improvement (ΔHSDS) from baseline at three years was +1.0 (rhGH-naïve, +1.2; pre-treated, +0.7). In pre-pubertal patients, ΔHSDS from baseline at three years was +0.94 (rhGH-naïve, +1.3; pre-treated, +0.7). Following three years of treatment, ΔHSDS from baseline was +1.3 in rhGH-naïve GHD patients and +1.1 in rhGH-naïve ISS patients. In pre-pubertal rhGH-naïve patients, ΔHSDS from baseline was +1.3 and +1.2 in GHD and ISS patients, respectively. Overall, 194 patients (66.0%) experienced adverse events (AEs; n=886 events); most were of mild-moderate intensity. Five patients (1.7%) had AEs that were suspected to be treatment-related (n=5 events). All reported neoplasms were benign, non-serious, and considered unrelated to rhGH therapy. No AEs of diabetes mellitus or hyperglycemia were reported.

Conclusions

Omnitrope® appears to be well tolerated and effective in the majority of patients, without evidence of an increased risk of developing unexpected AEs, diabetes mellitus, or new malignancies during treatment.
Łukasiewicz, determinism, and the four-valued system of logic
Authors: Rybaříková Zuzana
Published: March 2021

Jan Łukasiewicz is known primarily as the founder of the three-valued system of logic. It is also generally renowned that his reason for introducing many-valued systems of logic was an attempt to refute determinism. When he developed the three-valued and n-valued logic, he employed these systems in his arguments against determinism. On the contrary, Łukasiewicz preferred the four-valued system of logic that is not suitable for a refutation of determinism in his latest period. It seems, however, that determinism still interested Łukasiewicz, as he discussed its denial in his last work, the second edition of the book Aristotle’s syllogistic from the standpoint of modern formal logic. The aim of my paper is to introduce the issue and describe the relation of these two topics primarily in the latest period of Łukasiewicz’s work. There are several possible solutions to the issue. However, Łukasiewicz never addressed the issue clearly in his published works. Therefore, the solutions might be supported or contradicted by his unpublished works in the future.
Tykhonov triples and convergence results for hemivariational inequalities
Authors: Hu Rong , Sofonea Mircea , Xiao Yi-Bin
Published: March 2021

Consider an abstract Problem P in a metric space (X; d) assumed to have a unique solution u. The aim of this paper is to compare two convergence results u'n → u and u''n → u, both in X, and to construct a relevant example of convergence result un → u such that the two convergences above represent particular cases of this third convergence. To this end, we use the concept of Tykhonov triple. We illustrate the use of this new and nonstandard mathematical tool in the particular case of hemivariational inequalities in reflexive Banach space. This allows us to obtain and to compare various convergence results for such inequalities. We also specify these convergences in the study of a mathematical model, which describes the contact of an elastic body with a foundation and provide the corresponding mechanical interpretations.
Improving Pediatric Resident Safety Event Reporting Using Quality Improvement Methods
Authors: Mattes Monica D. , Sauers-Ford Hadley S. , Selleck Denise , Slee Christina , Natale Joanne E. , Rosenthal Jennifer L.
Published: March 2021

BACKGROUND AND OBJECTIVES:

Safety event reporting systems facilitate identification of system-level targets to improve patient safety. Resident physicians report few safety events despite their role as frontline providers and the frequent occurrence of events. The objective of this study is to increase the number of pediatric resident safety event submissions from <1 to 4 submissions per 14-day period within 12 months.

METHODS:

We conducted an iterative quality improvement process with 39 pediatric residents at a children’s hospital. Interventions focused on 4 key drivers: user-friendly event submission process, resident buy-in, nonpunitive safety culture, and data transparency. The primary outcome measure of number of pediatric resident event submissions was analyzed by using statistical process control. Balancing measures included time from submission to feedback, duplicate submissions, and nonevent submissions. As a control, the primary outcome measure was monitored for nonpediatric residents during the same period.

RESULTS:

The mean number of pediatric resident event submissions increased from 0.9 to 5.7 submissions per 14 days. Impactful interventions included a designated space in the resident workroom to list safety events to submit, monthly project updates, and an interresident competition. There were no duplicate submissions or nonevent submissions in the postintervention period. Time to feedback in the postintervention period had both upward and downward shifts, with >8 consecutive points above and below the baseline period’s centerline. The control group showed no sustained change in event submissions.

CONCLUSIONS:

Our improvement process was associated with significant increase in pediatric resident safety event submissions without an increase in the number of submissions categorized as duplicates or nonevents.
Age Cutoffs for Hospitalization at Hospitals Without Pediatric Inpatient Capability
Authors: Michelson Kenneth A. , Neuman Mark I.
Published: March 2021

OBJECTIVES:

To determine age cutoffs that hospitals without pediatric inpatient beds apply when hospitalizing children.

METHODS:

We conducted a cross-sectional study of patients <25 years old visiting emergency departments in 5 states in 2016 using the Healthcare Cost and Utilization Project State Emergency Department and Inpatient Databases. Hospitals were classified as adult (no pediatric inpatient beds) or pediatric capable (>0 pediatric beds). Referral rates were calculated for each year of life as transfers divided by transfers plus hospitalizations. Two age cutoffs were determined for defining pediatric patients: a specific cutoff (the age at which referral rates were significantly lower than those for younger patients) and an inclusive cutoff (the age at which referral rates differed most from those for younger patients).

RESULTS:

Among 389 581 transfers and hospitalizations, 91 967 (23.6%) occurred in adult hospitals. Referral rates at adult hospitals were 86.0% at age 15, 80.6% at age 16, 72.0% at age 17, and 30.5% at age 18. The specific age cutoff was 16 because referral rates were lower than those for ages 0 to 15 (P < .001). The inclusive age cutoff was 18 because the odds ratio for referral was lowest when comparing age 18 to ages 0 to 17.

CONCLUSIONS:

Children aged <16 years specifically define a population of pediatric patients, as defined by whether an adult hospital would hospitalize instead of transfer from an emergency department. Children aged <18 years inclusively define a population of pediatric patients. These age cutoffs may be used when studying patterns of national acute care for children.
Grief and Bereavement in Fathers After the Death of a Child: A Systematic Review
Authors: McNeil Michael J. , Baker Justin N. , Snyder Ian , Rosenberg Abby R. , Kaye Erica C.
Published: March 2021

CONTEXT:

The death of a child is devastating, and complicated grief adversely impacts parental physical and psychosocial well-being. Most research currently is centered on bereaved mothers, and the experiences of fathers remains underexplored.

OBJECTIVE:

We systematically reviewed the literature to characterize the grief and bereavement experiences of fathers after the death of a child.

DATA SOURCES:

We searched Medline, PsycInfo, Embase, and Cumulative Index to Nursing and Allied Health Literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

STUDY SELECTION:

Inclusion criteria encompassed English language articles published between 2007 and 2019 that evaluated the grief and bereavement experiences of fathers after the death of their child. We excluded studies describing paternal bereavement after the death of a child aged older than 21 years, stillbirth, miscarriage, or studies that did not specify age of death.

DATA EXTRACTION:

Extracted domains included study design, demographics, findings, and quality assessment.

RESULTS:

We screened 1848 deduplicated titles and abstracts and 139 full articles, yielding 21 articles for inclusion in this analysis. Fathers often avoided discussing their grief with others, returned to work earlier, and used goal-oriented tasks as coping strategies. Intense grief reactions and posttraumatic psychological sequelae diminished over time in mothers yet persisted in fathers.

LIMITATIONS:

Included studies were primarily descriptive in nature, without ability to ascertain causality. Limited paternal data exists in the literature compared with maternal data.

CONCLUSIONS:

Despite evolving gender roles, many fathers navigate loss through stoicism, self-isolation, and hard work. For some fathers, these coping mechanisms may be inadequate for navigating grief.
Improving optimization using adaptive algorithms
Authors: Kota László , Jármai Károly
Published: March 2021

In the research projects and industrial projects severe optimization problems can be met, where the number of variables is high, there are a lot of constraints, and they are highly nonlinear and mostly discrete issues, where the running time can be calculated sometimes in weeks with the usual optimization methods on an average computer. In most cases in the logistics industry, the most robust constraint is the time. The optimizations are running on a typical office configuration, and the company accepts the suboptimal solution what the optimization method gives within the appropriate time limit. That is, why adaptivity is needed. The adaptivity of the optimization technique includes parameters of fine-tuning. On this way, the most sensitive setting can be found. In this article, some additional adaptive methods for logistic problems have been investigated to increase the effectivity, improve the solution in a strict time condition.

Published: March 2021

Personally engaging musical experiences can be a driving moment, a motivating force in the development of the student. Their use in education and prevention can be of great importance. The emergence of music philetics theoretically makes it possible to anchor the issue of music experience in connection with music creation and to use inspiration from music therapy in the educational process, focus music experiences on the personal and social development of students and offer practical solutions for the implementation of music experience methods developing and enriching personalities of particular individuals. The concept of music philetics is not yet clearly defined and practically used. Further development will show its need in society and viability.
Youth coping strategies in a social conflict situation – theoretical implications
Authors: Borecka-Biernat Danuta
Published: March 2021

A young person who creates and implements certain life plans is exposed to situations of conflict related to school, contacts with peers and family relationships. For such a person, a conflict taking place in these three social spheres is an everyday, inevitable, and even natural situation. For some young people, conflicts with teachers, peers and parents constitute an important source of strong negative emotional stimulation and personal danger. There is no doubt that threats cause a lot of behaviours in a person, which are messages that describe a situation this person is currently in and whether it has the features of a difficult situation or not. Some young people, in the face of a dispute at school, in relationships with peers or at home, adopt destructive strategies in the form of an aggressive reaction to a conflict, avoiding active coping in the face of a conflict by engaging in other stress-free forms of activity or giving in to a conflict. However, there are also young people who cope with a social conflict situation well, treat a conflict as a challenge for themselves, which prompts them to mobilize their resources in order to overcome obstacles that prevent them from meeting their needs.

Authors: Караманов Алексей
Published: March 2021

The article analyzes the problems of interpreting objects in a museum space from different contexts and perspectives. Particular attention is paid to the pedagogical aspects of the use of narrative in the museum. The author emphasizes that museum narrative is a form of museum work that a priori attracts the attention of museum educators, animators, mediators, gallery managers, exhibition curators and examines the museum object from the point of view of cultural heritage, active education of the young generation, development of general cultural competences, interdisciplinary, civic education system. The author focuses on the importance of the appearance of various intermediaries in the museum, which indicates important changes that have taken place in modern museum practice and in cultural and educational work with visitors. The author concludes that education and narrative practices at the museum take place in a special, aesthetic and informative environment in which man feels his commitment to culture and the possibility of dialogue with it.

Intellectual disability is deficits in intellectual functions, adaptive functions, and these deficits occure during the developmental period (before the age of eighteen). Emotion regulation related to the functions and become the problems for children with mild intellectual disability. Emotion regulation is individual’s ability to refrain himself from improper behavior concerning negative and positive emotions that he feels, to manage himself so that he does not depend on his mood condition, to calm down himself when strong emotion arises, and to focus his attention when strong emotion appears. Emotion regulation is extremely needed for adaptation in maintaining relations with other people. The one of interventions that can be used to handle emotion regulation problem for children with intellectual disability is by giving emotion regulation skills system training. This research uses single subject design. The result of this research shows that emotion regulation skills system training gives positive impacts on cognitive and behavior aspects of the subject. The application of these skills in daily life is related to the roles of people around the subject who can understand how to apply the skills and remind the subject
Participants of Digital Legal Relations: Trends in Law and Business
Authors: Poduzova E. B.
Published: March 2021

Digital legal relations have undoubtedly become an important part of relations regulated under civil law and business. The socio-economic digital basis has set the main directions for the existence and functioning of the relevant legal superstructure and the practice of applying rules governing certain relations. In this regard, the legal status of digital intermediaries, including their legal capacity and tort, is of particular importance. It seems important to investigate the problems involving the grounds for holding aggregators and other digital intermediaries liable, as well as guarantees of protecting the rights of persons with whom these intermediaries interact. The legislation governing digital relations has undergone significant changes over the past few years. However, the complex of relations between digital intermediaries as new subjects of law and other persons remains unresolved, and the practice of imposing on such intermediaries civil and other types of legal liability is unsettled. In the paper, the author describes his approach to the consideration and solution of these problems.
The Termination of Treaties: To the Origins of the Formation
Authors: Ilinskaya О. I.
Published: March 2021

Over a long historical period of development, the institution of the termination of treaties has reached a high degree of maturity. Many of the norms that form it, having arisen in the treaty practice of states in antiquity, not only reflected the needs of their era, but gradually, passing from generation to generation, have transformed. Some of them have become part of the modern system of international law, having been enshrined in the Vienna Convention on the Law of Treaties (1969). Since ancient times, treaties have been terminated as a result of armed conflicts between states. The punishments for non-compliance with obligations envisaged by ancient treaties, as well as the religious oath designed to serve as a guarantee of their observance, were an expression of the idea of the inviolability of treaties. At the same time, the possibility of their termination was provided for as a result of violation of the fixed conditions. The main reason for the termination of treaties of the feudal period, as in antiquity, was wars. At the end of the 18th — beginning of the 19th century the agreements began to include provisions regulating their revision and even the ability to declare a complete rejection of them, notifying the counterparties. This practice testifies to the emergence of one of the currently widespread methods of terminating treaties, i.e. denunciation. Consideration of the practice of terminating treaties of the Soviet state is carried out taking into account the impact of the 1917 Revolution on the further progressive development of the law of treaties.

Published: March 2021

Although Turkey has significantly increased beef production in the last fifty years via livestock protection and domestic support policies, self-sufficiency and price stability has not been sufficiently achieved. Forecasting is essential to analyse the structure of the beef market and evaluate the sector. This study aimed to forecast beef production of Turkey by considering structural breaks. The data of the study was time series of beef production for the period 1961-2019 and it was obtained from the Turkish Statistical Institute and, Food and Agriculture Organization. Data was analysed and forecasted using ARIMA Model. The results indicated that ARIMA (1, 1, 0) is the best-fitted model and beef production would regularly increase in four years period and reach 1,133,687 tons in 2023. This research concluded that despite two structural breaks of beef production in 1983 and 2009, imports and domestic support policies substantially shaped the trend of beef time series in the last decade in Turkey.

A pesquisa teve como objetivo desenvolver um Sistema de Identificação de Risco de Contribuintes baseado em Redes Neurais para auxiliar a Administração Tributária Estadual na identificação de contribuintes mais propensos a assumir a condição de sonegadores do ICMS. Para tanto, foi desenvolvida uma rede neural artificial, denominada Sistema de Identificação de Risco de Contribuintes – SIRC, baseada num modelo perceptron de múltiplas camadas, do tipo alimentada adiante (feedforward), completamente conectada, composta por duas camadas ocultas e treinada com o algoritmo de retropropagação de erro (Backpropagation Error). A construção e operacionalização da SIRC deu-se a partir de informações extraídas dos bancos de dados da Secretaria da Fazenda do Estado da BAHIA (SEFAZ-BA), alimentados por informações prestadas pelos contribuintes, em uma amostra de 74.447 eventos. Na fase de treinamento, a Rede apresentou um índice de acerto de 71% na classificação dos contribuintes passíveis de autuação (ou não). Em relação aos contribuintes que foram autuados, a performance foi 94%. Estes percentuais atestam a eficácia do modelo como instrumento de apoio a decisões de fiscalização no âmbito da Administração Tributária Estadual.

Ao considerar a persistência, há longa data, das diferenças relativas às diretrizes contábeis provenientes do FASB e do IASB, bem como o principal objetivo de ambas as instituições em bem informar seus respectivos usuários para tomada de decisão, o presente trabalho objetivou estudar a relevância que os investidores em ações atribuem aos indícios de gerenciamento de resultados para sua decisão, conforme a plataforma teórica adotada. Para tanto, foram selecionadas companhias pertencentes à BM&F Bovespa, representantes das empresas que adotam as normas do IFRS, e companhias da Nasdaq, representando àquelas que adotam as normas do FASB. Utilizou-se o modelo de Dechow e Dichev (2002), para estimativa dos indícios de gerenciamento de resultados, posteriormente utilizando Regressão Linear para aferir a relevância destes indícios para a rentabilidade das ações. Como resultado, verificou-se que embora existam poucos indícios de que o investidor em ações leve em consideração, ou mesmo perceba, os indícios de gerenciamento de resultado em suas decisões, observou-se em alguns dos modelos significância estatística e em ordem inversa dos indícios de gerenciamento de resultados para a rentabilidade das ações.

In the central nervous system of mammals, there are specialized areas in which neurogenesis — neurogenic niches — is observed in the postnatal period. It is believed that astrocytes in the composition of neurogenic niches play a significant role in the regulation of neurogenesis, and therefore they are considered as a promising “target” for the possible control of neurogenesis, including the use of optogenetics. In the framework of this work, we formed an in vitro model of a neurogenic niche, consisting of cerebral endothelial cells, astrocytes and neurospheres. Astrocytes in the neurogenic niche model expressed canalorodopsin ChR2 and underwent photoactivation. The effect of photoactivated astrocytes on the expression profile of neurogenic niche cells was evaluated using immunocytochemical analysis methods. It was found that intact astrocytes in the composition of the neurogenic niche contribute to neuronal differentiation of stem cells, as well as the activation of astroglia expressing photosensitive proteins, changes the expression of molecules characterized by intercellular interactions of pools of resting and proliferating cells in the composition of the neurogenic niche with the participation of NAD+ (Cx43, CD38, CD157), lactate (MCT1). In particular, the registered changes reflect a violation of the paracrine intercellular interactions of two subpopulations of cells, one of which acts as a source of NAD+, and the second as a consumer of NAD+ to ensure the processes of intracellular signal transduction; a change in the mechanisms of lactate transport due to aberrant expression of the lactate transporter MCT1 in cells forming a pool of cells developing along the neuronal path of differentiation. In general, with photostimulation of niche astrocytes, the total proliferative activity increases mainly due to neural progenitor cells, but not neural stem cells. Thus, optogenetic activation of astrocytes can become a promising tool for controlling the activity of neurogenesis processes and the formation of a local proneurogenic microenvironment in an in vitro model of a neurogenic niche.

Para analisar os dados adotamos os pressupostos teóricos das epistemologias feministas nas dimensões crítica e construtiva, discussões da biologia da diferença e a análise de discurso de Foucault, na busca de que algo novo seja produzido. Os discursos apresentados são de homens e mulheres ocupando espaços bem definidos e distintos, o que reforça os discursos científicos do século XVIII da marcação da diferença e o que está presente em materiais didáticos, também são apresentados discursos de homens e mulheres desempenhando funções e ocupando espaços semelhantes e em processo de colaboração, além de discursos que não definiam quem eram homens e mulheres, apenas as atividades exercidas, esses discursos são próximos as teorias feministas. Discursos contraditórios que defendiam a igualdade, mas que demarcavam as diferenças entre homens e mulheres também foram encontrados. O ensino de Biologia pode possibilitar (re)construções, levantar dúvidas para repensar verdades (im)postas que são reafirmadas no ensino e mantém discursos de poder e dominação.

BACKGROUND: Bladder cancer is the tenth-most common cancer in worldwide and the majority are urothelial carcinomas. The depth of invasion plays important role in the prognostic and therapeutic factor in urothelial carcinomas. The expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) may associated with the progression of bladder carcinoma, such as depth of invasion. In this study, the correlation between these two markers in urothelial bladder carcinoma invasion will be analyzed.METHODS: An analytical observational research with cross-sectional were conducted on 54 formalin fixed paraffin-embedded tissue from radical cystectomy (RC) which were diagnosed as bladder urothelial carcinoma at the Anatomical Pathology Laboratory of Dr. Soetomo Academic Hospital, Surabaya and divided based on the T stage were immunostained using VEGF and MMP-9 monoclonal antibodies. The difference of VEGF and MMP-9 expression in T stage of bladder urothelial carcinoma were analyzed using Kruskal-Wallis and Anova test, the correlation between VEGF and MMP-9 expression in various T stage of bladder urothelial carcinoma were analyzed using Spearman test. RESULTS: This study showed no significant difference of VEGF expression among T stage of bladder urothelial carcinoma (p>0.05) but there was significant difference of MMP-9 expression in T stage of bladder urothelial carcinoma (p=0.043). There was a correlation between VEGF and MMP-9 in various T stage of bladder urothelial carcinoma (rs= 0.50, p=0.001).CONCLUSION: The significant correlation of VEGF and MMP-9 expression in bladder urothelial carcinoma may prove the synergistically role of both proteins in tumor invasion by MMP-9 degradation extracellular matrix.KEYWORDS: urothelial carcinoma, VEGF, MMP-9, T stage

Published: March 2021

Analyzed are trends in the construction of civil society in Uzbekistan. Examined is the structure of the Public chamber, described are its tasks, functions and responsibilities. Noted is, that in recent years a number of regulatory documents were adopted in Uzbekistan in this regard, and in some cases they contradict each other. The article recognizes not only organizational and legal aspects of formation of civil society, but also the need to strengthen its ideological foundations, increase civic engagement and introducing of democratic values. It is specially noted, that indicator of the mature level of civil society is not number of public organizations or official membership in them, but the level of citizens’ involvement in these organizations, i.e. social base of civil society, that determines socio-political stability in the country.

Published: March 2021

Background: Functional activities mostly done in daily life such as jumping, walking, running, and stairs ascending-descending require dynamic stability of the knee. The knee joint dynamic stability is required to have effective and efficient functional activities and to avoid injury when performing them. It can be achieved by increasing muscle strength through strengthening exercises with the aim of balancing the agonist muscles (quadriceps femoris) and antagonist muscles (hamstring) using the agonist- antagonist paired set (APS) method.Aim: The aim of this study is to find out the effect of strengthening exercise using APS method, compared to traditional set (TS) method, on single-leg hop performance.Material and Methods: The subjects of this study were 14 untrained healthy men aged 18-40 years old divided into 2 intervention groups, APS group and TS group. The variable evaluated was the distance of single-leg hop (SLH).Results: The results of this study showed a significant increase in SLH distance in APS group (p=0.005) and TS group (p<0.001) with no significant difference between the two groups (p = 0.933).Conclusion: Quadriceps femoris and hamstring muscle strengthening exercises in both APS and TS methods increase SLH distance although there is no difference between them. The APS method has an advantage compared to the TS method in terms of a relatively shorter time with comparable results.
