Conservative treatment in adult patient with reimplanted anterior teeth after traumatic avulsion with extensive bone loss: an 8-year follow-up
Authors: PITHON Matheus Melo
Published: March 2021

ABSTRACT Introduction: Orthodontic treatment in patients with traumatized teeth is a condition that needs good planning in order to achieve satisfactory results. Objective: To discuss approaches to orthodontic treatment of malocclusions associated with trauma followed by avulsion of anterior teeth, reimplanted after a short period of time. Case report: The treatment started with the distalization of upper posterior teeth, with the aid of mini-implants and sliding jigs, followed by the inclusion of anterior teeth in the arch, followed by intrusion of these teeth. Results: With the treatment, improved mobility of the anterior teeth was achieved, with better insertion into bone tissue. The most important factor for satisfactory treatment and a good prognosis for avulsion is the time the tooth remains outside the socket. Orthodontic treatment in patients with traumatized teeth is not contraindicated; however, clinical and radiographic aspects must be considered. Conclusion: Among the feasible orthodontic treatment options, the conservative approach can be a very favorable treatment alternative.
Comparing Bayesian Statistics and Frequentist Statistics in Serious Games Research
Authors: Westera Wim
Published: March 2021

This article presents three empirical studies on the effectiveness of serious games for learning and motivation, while it compares the results arising from Frequentist (classical) Statistics with those from Bayesian Statistics. For a long time it has been technically impracticable to apply Bayesian Statistics and benefit from its conceptual superiority, but the emergence of automated sampling algorithms and user-friendly tools has radically simplified its usage. The three studies include two within-subjects designs and one between-subjects design. Unpaired t-tests, mixed factorial ANOVAs and multiple linear regression are used for the analyses. Overall, the games are found to have clear positive effects on learning and motivation, be it that the results from Bayesian Statistics are more strict and more informative, and possess several conceptual advantages. Accordingly, the paper calls for more emphasis on Bayesian Statistics in serious games research and beyond, as to reduce the present domination by the Frequentist Paradigm.

Published: March 2021

The aim of this research is to study the impact ща the new technologies on the contemporary news radiobroadcasting.
The research methods include a half-structured interview with top managers of Russian news radio stations. The interview showed that digitalization has had a significant influence on almost all aspects of work of the news radio, from searching for information to professional requirements for the staff and the organization structure of the radio’s editorial board.
Having analyzed the results of the interview, the authors have made the following inferences.
The number of the competences the personnel of a news radio station is to possess has increased. The technological development has led to multitasking in the work of the personnel of a news radio: via the computer and mobile devices, they have to combine searching for information and working on the text with looking through and texting messages, and promoting their content in social networks. Due to its usability and operational efficiency, communication via messengers has almost replaced personal communication, telephone conversations and e-mail writing.
As for the effect of digitalization on the economic aspect of radio stations’ activity, it has been ambivalent. On the one hand, it has helped radio stations to minimize expenses on data storage, thanks to the cloud services. On the other hand, the work on the new formats, launch of new applications and hiring content managers have required other expenses. The most common change in the structure of a typical radio editorial board is the emergence of IT departments.
However, some aspects of work of news radio stations have remained unchanged despite digitalization. For instance, the use of FM-band is still popular with the market participants, who are not ready for expenses on transition to a new format.
Means of Creating Credibility Effect in Commercial Advertising Texts
Authors: Selemeneva Olga
Published: March 2021

The article deals with verbal means of creating credibility effect in creolized advertising texts. The topicality of the study is explained by the insufficiency of pragmalinguistic and psycholinguistic researches on the problem of implementing manipulation tools and persuasion methods in adverting texts. The detailed description of language means of creating advertising credibility as effect that causes mass consumption determines the originality of the study.
Within the frames of the study, verbal means of creating advertising credibility are identified and grouped in four categories: lexical, word-building, morphological, and syntactical ones. The author also determines and describes their functions, which include convincing the consumer of high quality of the item or service advertised, forming a positive emotional background, creating an illusion that the information in the ad is precise, full, and reliable.
The results of the study may be used for both academic purposes (in teaching relevant disciplines to undergraduate and postgraduate students, in study guides on mass media communication) and practical use (e.g. in organizing advertising campaigns).

Diagnostics of Motivating and Demotivating Styles of Teachers: “Situations-in-School” Questionnaire
Authors: Gordeeva T.O. , Sychev O.A.
Published: March 2021

There is a certain lack of of instruments for assessing the relationship between learning outcomes and the teacher’s communication style with students which determines children’s involvement in the learning process and their motivation.The article presents the results of adapting the self-determination theory-based questionnaire, Situations-in-School, for Russian-speaking educational environments on a sample of primary and secondary school teachers (N = 1400) from nine regions of Russia.This questionnaire assesses the four basic styles of teacher-student interaction (autonomy support, structure, control, and chaos) and their subtypes.The results of multidimensional scaling and confirmatory factor analysis indicate that the structure of the questionnaire at the level of items and subscales corresponds to a circular model (circumplex).The presence of eight subscales in the structure of the questionnaire is confirmed by CFA.The correlations of the scales with indicators of resilience and professional self-efficacy indicate construct validity.The questionnaire can be used both for research purposes and in the practice of school psychologists to assess the style of communication between teachers and students.

Authors: Koc Nagihan , Ballikaya Elif , Cehreli Zafer Cavit
Published: March 2021

Objective: To determine the prevalence and distribution of premature eruption and agenesis of premolars in a sample of Turkish children. Study design: A sample of 1715 patients aged 5 to 11 years was selected. Panoramic radiographs were used to assess premature eruption and agenesis of premolars. Developmental stage of erupted premolars was assessed using Demirjian’s method and selecting prematurely erupted premolars on the basis of clinical eruption with a root length less than half of their final expected root lengths. Statistical analysis was performed using chi-square test (p <.05). Results: One hundred fifteen (6.7%) of 1715 patients presented at least one premolar agenesis with no significant sex difference (56 boys, 59 girls). Mandibular second premolars were the most absent teeth. Multiple agenesis of premolars (3.4%) was more common than single agenesis (3.3%). A total of 85 (5.0%) patients (51 boys, 34 girls; no significant sex difference) had at least one prematurely erupted premolar, and maxillary first premolars were most commonly affected. Early erupted premolars were in stage D or E based on Demirjian’s dental formation scale. Conclusions: The prevalence of premature eruption and agenesis of premolars in Turkish children were 5.0% and 6.7%, respectively. Both conditions are not uncommon and may highlight the need for early diagnosis to prevent subsequent clinical problems.

Authors: Keskin Gül , Gündoğar Zübeyde Uçar , Yaman Merve , Tek Gün Burak
Published: March 2021

Objective: This study evaluated the microtensile bond strength (μTBS) of ion-releasing restorative materials to sound and caries-affected dentin (CAD). Study design: 60 teeth were randomly divided into 2 groups (sound dentin, CAD) and 5 subgroups of 6 samples each: conventional glass ionomer cement (GIC), resin-modified GIC (RMGIC), glass hybrid reinforced GIC (EQ), giomer (BII), and bioactive restorative material (ACT). μTBS analyses were performed and data were analyzed statistically. Results: The ACT group bonded to sound dentin and the BII group bonded to CAD showed the highest μTBS (p<0.05). The GIC, RMGIC, and ACT groups, showed significantly lower μTBS when bonded to CAD compared with sound dentin (p<0.05). However, in the BII group, there were no statistically significant differences between the samples bonded to sound and CAD (p>0.05). All groups except EQ that bonded to sound dentin showed predominantly adhesive failure. Conclusion: The use of the giomer can be recommended due to its more stable bond durability.

Authors: Doğusal Gülçin , Sönmez Işıl , Ünüvar Tolga
Published: March 2021

Aim: The aim of this study was to assess the association between dental caries, molar incisor hypomineralisation (MIH) and obesity in relationship with different vitamin D levels in children. Study design: This retrospective case-controlled study enrolled 455 children aged 6–18 years, who attended to both pediatric endocrinology and pediatric dentistry clinics at the Aydin Adnan Menderes University Hospital, Turkey. Vitamin D status was measured with serum (25(OH)D) concentrations. Body mass index (BMI) were used to determine adiposity. Caries status was assessed using the decayed-missing-filled teeth (dft) and (DMFT) index for primary and permanent dentitions using WHO standard methodology. MIH were diagnosed according to the EAPD criteria. Results: DMFT did not show any significant difference between obese and normal weight children in both age groups. However, in 6–11 age group, obese children had lower dft and the difference was statistically significant (p<0.001). Median caries index values and MIH prevelance among the obese and normal weight children found similar with deficient, insufficient and sufficient levels of serum 25(OH) D in both age groups. Conclusion: Our analyses provide no evidence to suggest that obese children are at increased risk for dental caries. Serum 25(OH)D concentrations would not seem to have a significant effect on dental caries and MIH in children.
Real-Time Tsunami Data Assimilation of S-Net Pressure Gauge Records during the 2016 Fukushima Earthquake
Authors: Wang Yuchen , Satake Kenji
Published: March 2021

The 2016 Fukushima earthquake (M 7.4) generated a moderate tsunami, which was recorded by the offshore pressure gauges of the Seafloor Observation Network for Earthquakes and Tsunamis (S-net). We used 28 S-net pressure gauge records for tsunami data assimilation and forecasted the tsunami waveforms at four tide gauges on the Sanriku coast. The S-net raw records were processed using two different methods. In the first method, we removed the tidal components by polynomial fitting and applied a low-pass filter. In the second method, we used a real-time tsunami detection algorithm based on ensemble empirical mode decomposition to extract the tsunami signals, imitating real-time operations for tsunami early warning. The forecast accuracy scores of the two detection methods are 60% and 74%, respectively, for a time window of 35 min, but they improve to 89% and 94% if we neglect the stations with imperfect modeling or insufficient offshore observations. Hence, the tsunami data assimilation approach can be put into practice with the help of the real-time tsunami detection algorithm.
How Artificial Intelligence Improves Agricultural Productivity and Sustainability: A Global Thematic Analysis
Authors: Fadziso Takudzwa
Published: March 2021

In the face of the agricultural sector's challenges, food security with an increasing human population and high demand for food is a significant problem. Traditional methods used by farmers have not been sufficient to meet the food requirements of the growing population. As a result, the agricultural sector has begun to deploy artificial intelligence to meet the demand for food and sustainability. This study was conducted to examine how AI improves farmers' productivity and sustainability. Data were analyzed using centering resonance analysis, t-test, ANOVA, and text mining news articles from 2014-2019 in Africa, Asia, Europe, and North America. Results show that AI is used primarily to increase productivity and efficiency and secondarily to address labor shortages and environmental sustainability concerns. The results at the regional level reflect the active adoption of AI in North America and Europe, with increasing efforts in Asia and Africa.
3D Printed Zn-doped Mesoporous Silica-incorporated Poly-L-lactic Acid Scaffolds for Bone Repair
Authors: Qian Guowen , Zhang Lemin , Wang Guoyong , Zhao Zhengyu , Peng Shuping , Shuai Cijun
Published: March 2021

Poly-L-lactic acid (PLLA) lacks osteogenic activity, which limits its application in bone repair. Zinc (Zn) is widely applied to strengthen the biological properties of polymers due to its excellent osteogenic activity. In the present study, Zndoped mesoporous silica (Zn-MS) particles were synthesized by one-pot hydrothermal method. Then, the particles were induced into PLLA scaffolds prepared by selective laser sintering technique, aiming to improve their osteogenic activity. Our results showed that the synthesized particles possessed rosette-like morphology and uniform mesoporous structure, and the composite scaffold displayed the sustained release of Zn ion in a low concentration range, which was attributed to the shield effect of the PLLA matrix and the strong bonding interaction of Si-O-Zn. The scaffold could evidently promote osteogenesis differentiation of mouse bone marrow mesenchymal stem cells by upregulating their osteogenesis-related gene expression. Besides, Zn-MS particles could significantly increase the compressive strength of the PLLA scaffold because of their rosettelike morphology and mesoporous structure, which can form micromechanical interlocking with the PLLA matrix. The Zn-MS particles possess great potential to improve various polymer scaffold properties due to their advantageous morphology and physicochemical properties. 
Pediatric empyema thoracis: our surgical experience
Authors: Albal Manisha , Bansod Prasad Y. , Mashru Deep
Published: March 2021

Incidence of empyema is increasing despite various treatment modalities available. Management of pediatric empyema remains a challenge due to factors like malnutrition, poverty, TB, delay in early intervention and incomplete treatment course. It is necessary to address these issues at ground level. A short 2-year prospective study was carried out at a tertiary care teaching hospital where 17 consecutive cases of pediatric empyema were managed.  Among 17 cases, all patients intercostal tube drainage (ICD) was required. Six patients underwent surgical interventions [2 video-assisted thoracoscopic surgery (VATS) and 4 open thoracotomies] while 11 were managed on ICD and antibiotics. Fibrinolytic therapy was not administered in any case. Follow-up showed good lung expansion with apparent rib crowding in 3 cases and no mortality. Majority of empyema in children are post pneumonic. Chest tube drainage, antibiotics along with intrapleural fibrinolytic is a safe and effective method of treating empyema thoracis in children in resource- poor settings and can reduce the need for invasive interventions.

«Сведущие люди» в Государственном совете второй половины XIX в.
Authors: Черникова Наталья Владимировна
Published: March 2021

Государственный совет как высшее законосовещательное учреждение Российской империи играл при монархе роль консультанта по всем законодательным вопросам. Необходимым требованием при выполнении столь важной функции была тщательность рассмотрения министерских проектов вплоть до прогнозирования возможных последствий их применения. В ряде случаев выполнение этой задачи было невозможно без привлечения «сведущих людей» – экспертов. В статье на основании анализа широкого круга источников проанализировано содержание понятия «эксперты» во второй половине XIX в., отношение к ним в Государственном совете, значение их участия в его заседаниях. Автор приходит к выводу, что, несмотря на усложнение стоявших перед Советом задач, отношение к институту экспертов не менялось и их потенциал не был использован в полной мере.

Стремительная цифровизация политического процесса и политических отношений способствует возникновению новых механизмов коммуникации между властью и обществом. Это делает актуальным вопрос об измерении эффективности различных сетевых коммуникативных механизмов и поиске основных маркеров подобных измерений. Цель исследования – анализ эффективности функционирования территориального Интернет-сообщества. В качестве основных переменных в проведении исследования используются следующие: интенсивность гражданского участия в работе изучаемого сообщества и качество обратной связи со стороны администраторов сообщества. Концептуальную основу исследования составили социоцентричный подход и теория информационного общества. Основными прикладными методами в работе стали сравнительный анализ и контент-анализ. В результате исследования установлено, что в течение большей части всего временного промежутка мониторинга наблюдался относительно стабильный и устойчивый показатель активности обращений граждан с помощью данного сообщества. Сделан вывод о повышении качества обратной связи со стороны администраторов сообщества в ходе его функционирования.
Assessment of climate change impacts on agriculture in Mali
Authors: SOUMAORO Tiémoko
Published: March 2021

This study examined the total, direct and indirect effects of climatic variables (temperature and precipitation) on crop yields (maize and millet) between regions located in close proximity to each other a spatial panel analysis of five administrative regions of Mali over a period of 30 years (1988-2017). Our results show that temperature and rainfall have direct, indirect and total effects on maize yield, while the direct effect on millet yield is not statistically significant. In other words, the effect on regions closely linked to region i where the change in temperature or rainfall occurred will be greater than the effect on more remote regions. In addition, the coefficient of variation of precipitation and the interaction between temperature and precipitation as well as area planted all have negative impacts on maize yield. However, millet yield is negatively correlated with drought in the study area. Based on these findings, decision-makers need to take into account that conditions in surrounding areas can influence cereal crop yields and that spillover effects differ between crop types. Investments in agricultural research and development must be encouraged to counter the effects of climate change.

Authors: Lubis Bugis Mardina
Published: March 2021

Objective: To describe the clinical and outcome of neonates born from women infected with COVID-19 while pregnant.

Design : Our study was observational cohort study

Material and Methods: We identified all neonates born between April - October 2020 at RSUP H. Adam Malik Medan from mothers who tested positive for COVID-19 during childbirth.

Result: From 122 deliveries mothers with suspected COVID-19, 43 (35.2%) mothers tested positive for COVID-19. All neonates were examined in the first 24 hours of life, and there were 5 (11.6%) neonates identified as positive for COVID-19. 2 (40%) neonates had symptoms of shortness of breath, and 1 (20%) had symptoms of fever. 2 (40%) neonates died.

Conclusion: Given the lack of current research, vertical transmission cannot be confirmed or refuted. The existing literature does not support the prohibition of breastfeeding or the separation of mothers and newborns. Further evidence is needed to establish definite guidelines and recommendations

The Covid-19 pandemic has brought countries in the world and Indonesia is no exception entering a new phase of life. The purpose of this study is to find various policy packages by the Government and individual countries to protect their citizens in relation to various laws and regulations to overcome the Covid-19 pandemic. This type of research uses normative legal research, and the research methodology used is Foucault's theory of power relations, that is, understanding will be built to find a synthesis in this study. The results of research investigations are related to various policy packages issued by various countries and also by the Indonesian Government to protect their citizens to overcome the Covid-19 pandemic including the various effects of its dominance through large-scale social restrictions and new normal life Covid-19. However, it turns out that this provision is not effective in Indonesia because people tend to ignore it. The solution offered is that the community as a civil society must be able to manage issues in the face of inadequate public compliance with various laws and regulations that govern the handling of the Covid-19 pandemic. Therefore, Civil society in Indonesia must be encouraged to change the basis of thought so that it has the same spatial frequency as the Government
Examining change management theories through case studies
Authors: Bandyopadhyay Dr. Prabir Kumar , Ghosh Sankar
Published: March 2021

The objective of the present paper is to examine the already established change management success factors and respective theories, in the light of personal experience in five organizations as a change agent. And examine whether these theories are sufficient to explain the success and failure of change management in Indian organisations. We took the constructivists approach while studying the change management phenomenon. Hence, we relied on a qualitative method.  As there is no single truth, the reality needs to be interpreted and the truth discovered based on the collective experiences of the researchers. Therefore, the theoretical perspective of our research is interpretivism. We have used narrative inquiry based on memory as we have first-hand knowledge over a period in each of the five cases and in some cases; we both have experience in a different time period. This approach is appropriate in this case of knowledge of change management, which is unquantifiable and where it is not easy to transfer the experience. Our findings mostly support the existing theories and steps in change management. Out of the ten steps one step is ““Form partnership with stakeholders for guiding coalition” is not supported. Existence of good management practices are a perquisite for a successful change. Institutionalize change is an important step. As there is a gap between observation and articulation of this paper there are chances of missing important observations that could have considered for drawing more insightful conclusion. The study is based on individual’s observation therefore it may have cognitive biases. The case study narratives will give an insight to a practitioner how different organisations management change management process. The findings presented will also be helpful to a practitioner. The strongest new finding is the need to have the good management practices in place before going ahead with change.

La utilización del modelo de gobernanza policéntrica, de Elinor Ostrom, como medio de salvaguardar la efectividad de la gestión democrática de las cooperativas en las situaciones de representación delegada
Authors: De Souza Leonardo Rafael
Published: March 2021

De acuerdo con el principio de gestión democrática, las cooperativas son organizaciones gestionadas por sus miembros, los cuales participan activa y directamente en la determinación de sus políticas y en la toma de decisiones. Sin embargo, cuando la sociedad cooperativa asciende considerablemente, en términos de cobertura territorial o de cantidad de miembros, la Ley de Cooperativas brasileña establece la posibilidad de la representación delegada en el ámbito de las asambleas generales. En este sentido, el presente trabajo tiene como objetivo analizar el modelo de gobernanza policéntrica, de Elinor Ostrom, utilizándole como palanca de sustentación de la gestión democrática de las sociedades cooperativas consideradas de grande porte, que adoptan la posibilidad de representación delegada. El objetivo es confirmar que la adopción de la representación delegada conforma un sistema de gobernabilidad pluridemocrática y sistémica que tanto no afecta la esencia participativa del conjunto de miembros, como resguarda la democracia de la gestión preconizada por la máxima de un hombre un voto. Para materializar la investigación se va a utilizar el método inductivo de abordaje, con empleo de la investigación directa e indirecta.

Dignidad y género: la eficacia de la axiología cooperativa en la conformación del principio de la igualdad humana
Authors: De Miranda José Eduardo , Corrêa Lima Andréa
Published: March 2021

En la medida que la humanidad evoluciona en el tiempo y prospera en el espacio, los valores existenciales cambian. La codicia y los intereses de orden material, afectan la estabilidad existencial de las personas. Hombres y mujeres pierden la identidad humana y ocupan espacios sociales en virtud de su condición de género. La diferencia se establece en el seno de las diferentes sociedades globales, y el hombre asume los puestos de poder y de crecimiento social y laboral. Sin embargo, cuando hombres y mujeres sufrían las consecuencias materiales y morales de la Revolución Industrial, la práctica cooperativa instaurada por los Probos Pioneros de Rochdale instituyó un nuevo orden moral, y axiológico, que enalteció la igualdad y la fuerza colectiva para el enfrentamiento de las vicisitudes de la existencia. Los valores cooperativos, entonces, se muestran adecuados a la disminución de la actitud comportamental que afecta la diversidad, y tiraniza la igualdad.

Igualdade de género e governação cooperativa em Portugal- uma análise jurídica e fática
Authors: Meira Deolinda , Martinho Ana Luisa
Published: March 2021

Este estudo demonstra que há uma conexão profunda entre o regime jurídico das cooperativas, que se baseia num conjunto de princípios e valores definidos pela Aliança Cooperativa Internacional e que integram o conceito de identidade cooperativa, e a igualdade de género. A governação democrática, que carateriza as cooperativas, impõe um regime de representação equilibrada entre mulheres e homens nos órgãos de administração e de fiscalização das cooperativas. No entanto, os dados fornecidos pelo Portal de Credenciação da CASES evidenciam uma representação desequilibrada. Impõe-se a adoção pelas cooperativas, por via estatutária ou regulamentar, de medidas positivas, tais como as quotas de género, que assegurem uma representação equilibrada entre homens e mulheres nos órgãos das cooperativas.

Situación y perspectivas de la Sociedad Cooperativa Europea
Authors: Vargas Vasserot Carlos
Published: March 2021

El Estatuto de la Sociedad Cooperativa Europea (SCE) está integrado por dos disposiciones complementarias. De un lado, el Reglamento CE 1435/2003 «relativo al Estatuto de la Sociedad Cooperativa Europea» (RSCE) y, de otro, la Directiva 2003/72/CE del Consejo «por la que se completa el Estatuto de la Sociedad Cooperativa Europea en lo que respecta a al implicación de los trabajadores». Mediante esta forma jurídica supranacional se pretendía dotar a las cooperativas europeas de un instrumento que les permitiera desarrollar actividades transfronterizas de carácter internacional. Pero después de casi diez años de su puesta en marcha, la figura supranacional no ha funcionado. Hasta 2012 sólo se habían constituido en Europa veinticuatro sociedades cooperativas europeas, con un número de trabajadores inferior a cincuenta, siendo además llamativo el escaso número de las creadas en países con un movimiento cooperativo tan activo, como son Francia, España o Alemania. Consciente de esta realidad, la Comisión europea evaluó a través de una consulta pública los motivos de la escasa adhesión del cooperativismo europeo al estatuto de la SCE y en febrero de 2012 se publicó un Informe sobre la aplicación del RSCE, que finalizaba con la necesaria revisión de su contenido. El presente estudio analizará el origen y las razones de la creación de las entidades supranacionales en el Derecho de sociedades europeo, para posteriormente analizar el contenido del RSCE, su complejo sistema de fuentes y las razones del fracaso de la figura, exponiendo las diversas medidas de reforma propuestas por la Comisión Europea, con objeto de hacer el tipo legal más atractivo para el movimiento cooperativo europeo.

Valores cooperativos, derecho cooperativo y jóvenes
Authors: Fici Antonio
Published: March 2021

El artículo trata, desde diversos puntos de vista, el tema de la relación entre valores cooperativos y jóvenes. Tras discutir el significado y papel de los principales valores cooperativos, es decir, la mutualidad, la persona y el altruismo, que son valores claves en la estructuración de la identidad cooperativa, el artículo se detiene en la necesidad de los juristas cooperativos, sobre todo los pertenecientes a las nuevas generaciones, de defender y promover estos valores, y por lo tanto la identidad propia de las sociedades cooperativas. De hecho, sólo una cooperativa con una identidad propia que se base en dichos valores podrá contribuir a un desarrollo sostenible y a un mayor pluralismo y democracia del mercado, que hoy, más que nunca, son esenciales para un mundo mejor.

Presupuestos teóricos para la regulación jurídica de las cooperativas de consumo en Cuba
Authors: Rodríguez Musa Orestes , Ferro Álvarez Leticia Isabel
Published: March 2021

El proceso de actualización del modelo socioeconómico cubano ha implicado la expansión de las cooperativas. Sin embargo, la legislación que regula este proceso no concibe a las cooperativas de consumo, aun cuando las dificultades para el consumo de artículos vitales para las personas resultan evidentes. Por tanto, el objetivo de este trabajo es fundamentar los presupuestos teóricos en que debe sustentarse la regulación jurídica de las cooperativas en Cuba, a fin de que conciba a las cooperativas de consumo como un medio para la satisfacción de las necesidades de sus asociados y de la comunidad. Para ello se parte de una aproximación a la definición de las cooperativas de consumo. A continuación, se analizan las actuales limitaciones jurídicas para la instrumentación de este tipo de cooperativas en Cuba, y se termina argumentando los presupuestos teórico-jurídicos para este propósito.

Kinetics of human butyrylcholinesterase inhibition by 1,9-dimethyl-methylene blue
Authors: BIBEROGLU Kevser
Published: March 2021

Alzheimer’s disease (AD) is an irreversible and progressive neurodegenerative disorder, characterized by β-amyloid plaques, neurofibrillary tangles and loss of cholinergic neurons. Butyrylcholinesterase (BChE) inhibition is one of the most critical strategy for the treatment of AD since BChE causes inactivation of neurotransmitter acetylcholine and has positive effects on promoting the formation of β-amyloid fibrils. Our previous studies showed that various phenothiazine-derived compounds such as thionine and toluidine blue O (TBO) cause a potent inhibition of human cholinesterases. TBO was also found to reduce amyloid precursor protein processing in-vitro and in-vivo models of AD. In this study, it was aimed to determine the inhibitory effect of 1,9-dimethyl-methylene blue (DMMB), a phenothiazine-derived compound, on human plasma BChE and explore its inhibitory mechanism.
The inhibition of human BChE was assessed by the colorimetric method of Ellman using butyrylthiocholine as substrate and 0-0.375 μM of DMMB. The kinetic findings showed that DMMB acts as a linear mixed-type inhibitor of human BChE with Ki value of 23 ± 0.004 nM and α= 3.6 ± 1.6. It was concluded that DMMB, which is a potent inhibitor effective at nM level may be helpful in designing new cholinesterase inhibitors for the treatment of AD.
Landmark guided internal jugular vein catheterization in infants undergoing congenital heart surgery
Authors: SEÇİCİ Serkan
Published: March 2021

Objectives: Central venous catheterization is an important procedure for infants undergoing heart surgery. Ultrasound-guided methods have been shown to decrease failure and complications. The goal of the present study was investigate the effect of anatomical landmark technique during internal jugular vein access in low-weight infants undergoing congenital heart surgery.
Methods: A total 98 infants (median age was 16.5 days, median weight was 3275 g) who underwent internal jugular vein catheterization between January 2017 and October 2019 were retrospectively analyzed. All catherizations were performed by a pediatric heart surgeon. Data including demographic characteristics of the infants, success rate, and catheter-related adverse events were recorded.
Results: Success rate was 94.9% (n = 93). There were three arterial puncture (3.1%) and hematoma occurred in five patients (5.1%). Central venous catheterization of 78 (79.6%) patients were successful at the first attempt.
Conclusions: Our study suggest that landmark technique still seems useful by experienced operators and is safe and effective in infants weighing less than 5 kg undergoing congenital heart surgery.

Plasma chemistry is part of the development of high technology that meets the modern requirements of greening and resource conservation. The study of physic-chemical laws and processes occurring in the zone of action of electric discharge plasma near the surface of a liquid is of high scientific and applied interest. In the study, developed and patented by a team of authors, plasma-chemical reactors were used, which implement the treatment of a liquid with both barrier and glow discharges near the surface of the liquid phase in a flow-through mode. Solutions of primary and secondary aliphatic alcohols were used as a model object of plasma-chemical treatment. As a result of the study, the mechanisms of liquid-phase oxidation of primary and secondary aliphatic alcohols during plasma-chemical treatment of water were proposed. The emission spectra of electric discharges at the gas-liquid interface in the presence of dissolved organic substances were obtained and analyzed. Spectral studies of electrodischarge plasma in the liquid-liquid zone confirmed the differing composition of the inorganic oxidation products of primary and secondary aliphatic alcohols. When deciphering the spectra of barrier and glow discharges, the characteristic emission bands of nitrogen N2, OH-radicals and nitric oxide, as well as lines of atomic hydrogen H and oxygen O were shown. In addition, the effect of the nature of the organic substances contained in the treated water on the characteristics of the electric discharge plasma was shown
Nexus between Poverty and Child Labor: A Case Study in Narayanganj Area of Bangladesh Using Binary Logistic Regression
Authors: Akter Shamima , Akram Wasim
Published: March 2021

The purpose of the study is to see how poverty influences child labor. To carry out the study, moderate poor people have been considered as respondents. Kalibazar and Langalband regions of Narayanganj district have been selected. Random sampling technique and Focused Group Discussion with children have been taken to conduct the study. Data has been collected from 50 Household Heads and 50 Children (male and female). For economic analysis, the Binary Logistic Regression model has been undertaken to see the relationship between poverty and child labor.  The analysis shows that the odds ratio indicates that drop-out children from school are 11.34 times more likely to go for taking the occupation of child labor due to poverty (major cause) than those children who have been dropped out due to other reasons (reference category). The study also shows that the families having no loan are 0.444 times less likely to go for child labor due to major causes (poverty) than that of the families having a loan. Moreover, the odds ratio corresponding to the children who use their income to help their families is 3.26. It means that the children who use their income for family purposes go 3.26 times more likely to take the occupation of child labor due to a major cause (poverty) than those children who do not use their income for family purposes. At the same time, the children who use their income for treatment purposes go 1.45 times more likely to take the occupation of child labor due to poverty (a major cause) than those children who do not use their income for treatment purposes.
