Authors: Younus Awais , Dastgeer Zoubia , Rathour Laxmi , Mishra Lakshmi Narayan , Mishra Vishnu Narayan , Pandey Shikha
Published: September 2022

We relate this article to the emerging idea of distinguishability of conformable linear hybrid time-invariant control systems. To obtain the necessary and sufficient conditions ofα\alpha-distinguishability for fractional cases, we develop the Leibnitz rule for conformable derivatives. Furthermore, with the help of a study of Laplace techniques, a more simple criterion ofα\alpha-distinguishability for the fractional linear system is developed.
Deep Mining Algorithm of Online Purchase Behavior Data Based on Decision Tree Model
Authors: Cui Jiayi
Published: September 2022

It is difficult to mine online buying behavior data by ignoring the classification of online buying behavior data, and the precision and recall are both on the low side. The training set of online buying behavior data is processed by top-down recursion, and a single decision tree is created recursively, and a decision tree classification model is constructed. Based on the classification results of behavior data, the regular estimation of online shopping features is calculated by preprocessing customer behavior features, and the deep mining algorithm is designed. Experimental results show that the decision tree model has good data clustering effect. Based on this, the precision and recall of online shopping behavior data mining are high, and the application performance is ideal.
Çerçeve sözleşme kavramı, çerçeve sözleşmelerin amacı ve ekonomik fonksiyonu
Authors: ŞEN DOĞRAMACI Hayriye
Published: September 2022

Sosyal ve ekonomik ihtiyaçlar zamanla değişiklik gösterir. Kişiler arasındaki hukuki ilişkilerin de bu değişikliğe paralel olarak esnek bir biçimde düzenlene-bilmesi oldukça önemlidir. Türk Hukuk sistemine hâkim olan sözleşme özgür-lüğü ilkesi ve onun bir alt görünümü oluşturan tip ve içerik özgürlüğü, sözleş-meler hukuku alanında arzu edilen esnekliği sağlamaya hizmet eder. Çerçeve sözleşmeler hukuki dayanağını sözleşme özgürlüğü ilkesinden alır. Çerçeve sözleşmeler, borçlar hukuku alanında yer alan ve edim değişimini konu alan sözleşmelerden değildir. Çerçeve sözleşmeler, edim değişimini konu alan ileride yapılacak münferit sözleşmeleri tamamlayıcı bir rol üstlenir.

Edim değişimini konu almayan ve birden çok münferit sözleşmeyi tamamla-makla görevli çerçeve sözleşmeler her şeyden önce taraflar arasında sürekli bir ilişkiye vücut verdiği için, tüm sürekli borç ilişkileri için söylenebilecek birtakım avantajlara sahiptir. Çerçeve sözleşmelerin bunun ötesinde sürekli bir borç iliş-kisinde karşılaşılabilecek risk ve belirsizlik faktörlerine karşı nasıl görev üstlen-diği onun ekonomik fonksiyonunun belirlenmesiyle ortaya çıkarılacaktır. Bu çalışmada hukukun ekonomik analizine yönelik kaynaklardan yararlanılarak, çerçeve sözleşmelerin ekonomik fonksiyonu ortaya konulmaya çalışılacaktır.

Created PKM, which are characterized by high adhesion/cohesion characteristics (29.0-36.5)/(40.0-43.6) MPa, and PKM with a content of MeOM:NiOM-0,32%; CuOM-0,33%; ZnOM-0,34%, which leads to an increase in adhesion/cohesion properties, namely: (35,7–37,0) / (42,8–43,9) MPa and have high performance properties: indicators of water resistance of concrete samples protected by PKM, exceed this indicator of concrete initial up to 3,75 times; initial PKM and modified with MeOM are resistant to sea water and salt fog, as well as to action of special reagents at low temperatures - frost resistance of such concrete after 50 freeze-thaw cycles is 1,0–1,1, ie, concrete coated with PKM becomes frost resistant; concrete cubes with a protective coating have no damage, no changes in the surface of the samples and the surface of the coating, hovewer, not protected concrete cubes collapsed. According to the IR data, the formation of the amide group -CONH- as a result of the addition of hydrogen of the CH group of the double bond of the MeOM molecule to the nitrogen of the NCO group of TDI was established; the change in the profile of valence and deformation bands oscillations of CH bonds of different groups indicates reactions involving CH bonds and the possibility of complex compounds formation that affect the structure of the polymer, that is to say, the active compounds are fixed in the polymer macrochain, which prevents their diffusion on the material surface and their subsequent removal and prolongs the protective functions of the coating, which has high adhesion/cohesion strength, resistance to UV radiation, biocorrosion, and chemical agents, enhances heat resistance and provides high performance.
Динамика религиозного экстремизма в России в богословских, правовых и психологических подходах к социальной и личностной; Dynamics of Religious Extremism In Russia In Theological, Legal and Psychological Approaches to Social and Personal
Authors: Maulana Amy , Buana Dana Riksa , Magomedovich Abdulaev Ibragimgadzhi
Published: September 2022

After the collapse of the Soviet Union in the post-Soviet era, a spiritual vacuum was formed in the conditions of deterioration of the political and economic situation. In the North Caucasus region, during the formation of the Russian state, it was quickly filled with religion: Wahhabism emerged, spread and increasingly declared itself religious extremism. Several terrorist attacks have occurred not only in the North Caucasus, but also in several Russian cities. This article describes the dynamics of religious extremism in Russia from the point of view of the theological, legal and psychological approach to social and personal. With regard to the soft approach, Russia can implement programs of deradicalization and counter-radicalization. In this regard, Russia may create a National Agency for Combating Terrorism and launch a deradicalization project and create a Deradicalization Center for convicted terrorists. Efforts to prevent the development of religious extremism in Russia are being undertaken not only with a legal approach, but also with a theological approach, since it is connected with Islamic concepts.
The Influence of International and Islamic Law on Labor Laws in Indonesia and Morocco
Authors: Maksum Muhammad , Afiyanah Yayuk
Published: September 2022

Work agreements between workers and employers form the basis for determining rights and obligations. Employment agreements are influenced by the laws governing a country and its historical experience. This study aims to analyze the influence of international and Islamic law on labor law in two countries, both Indonesia and Morocco. The research method used is a qualitative research method with a comparative approach. The results of the study stated that by comparing the provisions of work agreements from three sources of law, namely Indonesian, Moroccan, and Islamic law, it was found that international law had an effect on national law. Islamic law has little effect on work agreements. The influence of Islamic law is found more in Moroccan regulations than in Indonesian regulations. Several different concepts regulated in the source of law include the concept of work agreements, restrictions on the age of children who can enter into work relationships, the object or work employed, and the designation of work areas. This research has implications for the openness of international work transactions or the acceptance of foreign workers due to the same arrangement although with certain restrictions according to a country's policy.
Impacto económico y social de la formalización laboral en México
Authors: Robles Ortiz David , Beltrán Jaimes Luz Dary , Delgado López María Del Carmen
Published: September 2022

En México cerca del 60 % de la población trabajadora se encuentra en la informalidad, por lo que resulta importante analizar el impacto de este fenómeno en el producto de la economía y el bienestar de la población ante la formalización laboral. En consecuencia, se sigue el modelo de Leontief, ampliado a una matriz de contabilidad social, para determinar dicho impacto. Como resultado se encuentra que el output total de la economía aumentaría en 17,58 % y que, aunque la desigualdad sigue presentando los mismos índices, el ingreso de la población mejoraría y la pobreza disminuiría.
Speculative bubble tendencies in time series of Bitcoin market prices
Authors: Demmler Michael , Fernández Dominguez Amilcar Orlian
Published: September 2022

This article explores the concepts of cryptocurrencies and speculative bubbles, as Bitcoin’s price behaviour shares characteristics with speculative bubbles that have occurred in recent years. Using a quantitative research design, the study examines daily market prices for the period between 2013 and 2019. Statistical moments, return stationarity, TARCH-type model estimations and Supremum Augmented Dickey-Fuller and Generalised Supremum Augmented Dickey-Fuller tests are analysed. We find evidence for multiple speculative bubble tendencies in Bitcoin prices caused by speculation, which reached their maximum at the end of 2017. Our results are in line with recent studies, which characterise Bitcoin as both highly speculative and vulnerable to financial bubbles.
Desigualdades e interseccionalidad: aproximación a un índice de justicia social
Authors: Nova Laverde Mariluz , Rojas Mora Jaime Edison , González Montero Sebastian Alejandro
Published: September 2022

La teoría de la interseccionalidad postula la importancia de analizar la relación entre desigualdades para configurar estrategias de justicia social. Considerando que lo que se mide influye en lo que se busca colectivamente (y viceversa), esto es, que el posicionamiento de ciertos indicadores puede incidir en el modo en que las sociedades se perciben y en las políticas públicas, es necesario el diseño de un índice de justicia social (IJS) que capture interseccionalidad. La propuesta de este se sustenta en los debates de filosofía política y en la revisión de ejercicios de innovación en la medición estadística.

Authors: Fialho Lia Machado Fiuza , Sousa Roberta Araújo de , Sousa Francisca Genifer Andrade de
Published: September 2022

Objetivou-se compreender os fatores que influenciaram a transferência de alunos da rede pública para a rede privada de ensino na educação básica do município de Fortaleza-CE. A pesquisa, de abordagem qualitativa, do tipo estudo de caso, foi desenvolvida mediante entrevista semiestruturada com seis mães de alunos que optaram por descontinuar a escolarização dos seus filhos na rede pública de ensino, matriculando-os em uma escola privada na periferia da capital cearense. Os dados coletados foram submetidos à análise de conteúdo, para a qual emergiram três categorias: a) perfil das entrevistadas, que elucidou a baixa condição financeira de suas famílias e dificuldade para custear o ensino privado; b) motivações para a transferência, dentre elas o baixo rendimento na aprendizagem e a falta de qualidade da escola pública; e c) satisfação com a escola privada, decorrente do acompanhamento mais individualizado, maior interação da escola com a família e ensino melhor qualificado. Conclui-se que as precariedades da escola pública fazem com que famílias se sacrifiquem financeiramente para manter seus filhos estudando em escola privada.

Authors: Zatolokin V. V. , Vechersky Yu. Yu. , Manvelyan D. V. , Kozlov B. N.
Published: September 2022

Aim. To assess the effect of a pharmacological protocol for the prevention of radial artery spasm, which is based on the systemic and local use of dihydropyridine calcium channel blockers, on the long-term outcomes of autoarterial coronary artery bypass grafting.

Material and methods. According to the protocol, oral nifedipine at a dose of 5 mg/day is prescribed 3 days before surgery. Then, after the radial artery is isolated, the vessel is preserved in a solution of nifedipine (adalat) until it is used. After releasing the clamp from the aorta, a nifedipine (adalat) is infused intravenously at a dose of 0,63 mg/h. In the postoperative period, the infusion of nifedipine continues for 6 hours. In the future, patients are recommended to take dihydropyridine calcium channel blockers at a dose of 5 mg/day after discharge from the hospital.

Results. The use of the pharmacological protocol (n=225) is associated with a lower number of major cardiovascular events (mortality, myocardial infarction, stroke) compared with the control group (n=230) (9,3% and 15,7%, p=0,031) during the 5-year follow-up. This result was achieved mainly by reducing the incidence of myocardial infarction (6,2% and 12,6%, p=0,018). Also, the use of the pharmacological protocol led to a decrease in repeated revascularizations (4,4% and 16,1%, p=0,0001) compared with the control group.

Conclusion. The use of a pharmacological protocol for the prevention of radial artery spasm based on the systemic use of dihydropyridine calcium channel blockers improves the long-term outcomes of autoarterial coronary artery bypass grafting.

Authors: Petlin K. A. , Kosovskikh E. А. , Chernykh Yu. N. , Kozlov B. N.
Published: September 2022

Aim. To assess the severity of heart failure (HF) 1 year after aortic valve replacement with a novel bioprosthetic valve with the “easy change” system.

Material and methods. The study included 59 patients (24 men and 35 women) diagnosed with degenerative aortic valve disease without concomitant cardiac pathology. The mean age of the patients was 69,6±4,3 years. An assessment of NYHA HF class using six-minute walk test was carried out. The venous plasma level of N-terminal pro-brain natriuretric peptide (NT-proBNP) before and after surgery was also used to determine the severity of HF. In 31 patients (52,5%), NYHA class III HF was determined before surgery.

Results. Comparative analysis of HF classes revealed a significant difference. Thus, after implantation of MedEng-BIO prosthetic aortic valve, the distance of the six-minute walk test increased by an average of 125 m (p=0,001). NT-proBNP level decreased from 162,2 pg/ml to 63,7 pg/ml (p=0,003).

Conclusion. One-year follow-up of patients after implantation of a novel bioprosthetic aortic valve showed an objective decrease in the severity of HF according to six-minute walk test and NT-proBNP level in venous blood plasma.

Aim. To evaluate changes of left ventricular (LV) diastolic function in patients with multivessel coronary artery disease before coronary artery bypass grafting (CABG) and in the early postoperative period (7-10 days), as well as to assess the relation- ship between diastolic LV dysfunction and postoperative atrial fibrillation (POAF).

Material and methods. This original prospective study of included 50 patients undergoing CABG at the Cardiac Surgery Unit № 1 of the N. V. Sklifosovsky Research Institute for Emergency Medicine from December 2020 to December 2021. All patients underwent standard echocardiography before and after surgery. Diastolic function was assessed using the following parameters: septal mitral annulus velocity (e’septal), lateral mitral annulus velocity (e’lateral), the ratio of the peak early transmitral velocity to peak early diastolic velocity of the mitral annulus movement (E/e’), left atrial volume index (ml/m2), peak tricuspid regurgitation velocity (m/s), the ratio of the peak early to late filling velocity (E/A).

Results. After CABG, 35 patients maintained sinus rhythm in the early postoperative period (group 1), while 15 patients had POAF (group 2). According to echocardiography, type 1 diastolic dysfunction prevailed in both groups; types 2 and 3 LV diastolic dysfunction were not identified. Among the parameters characterizing myocardial relaxation, in group 1 after CABG, a significant increase in the peak E (p=0,001) was noted, and due to this, the normalization of the E/A ratio was recorded (p<0,0001). An increase in e’lateral (p=0,05) was also revealed, in connection with which an increase in the E/e’ (p=0,02) was noted. In the group of patients with POAF, such changes were not detected. Left atrial volume index (ml/ m2) was significantly higher in the POAF group (p=0,02).

Conclusion. Surgical myocardial revascularization has a positive effect on LV diastolic function. Improvement in LV diastolic function after CABG may be a sign of the restoration of hibernating myocardium function, while the absence of LV diastolic function improvement, together with left atrial dilatation, may be predictors of early POAF.

Novel biological markers, such as fibrosis marker galectin-3, peptide hormone adrenomedullin, soluble ST2, chemokine CX3CL1, surrogate marker of vasopressin, and others, are every year one step closer to being introduced into health practice. Over the past decades, significant progress has been made in the study of cardiovascular biomarkers. A key moment was the introduction of deter mining the concentration of natriuretic peptides used as markers for the diagnostic and prognostic evaluation of patients with heart failure. Currently, in order to search for novel markers for early diagnosis and risk stratification, studies have been conducted on the analysis of promising inflammatory marker tenascin-C (TNC) in cardiovascular patients. Data have been obtained that allow us to consider TNC as a tool for risk stratification and assessment of cardiovascular disease prognosis. The combination of TNC with other biological markers, in particular brain natriuretic peptide, may improve prognostic power. Nevertheless, serial testing to assess the prognosis and effectiveness of ongoing treatment, including in the conditions of a multimarker model, requires further research.

Aim. To conduct a comparative analysis of clinical and functional parameters and quality of life (QoL) in patients with chronic thromboembolic pulmonary hypertension (CTEPH), depending on the presence of a depressive disorder in long-term postoperative period.

Material and methods. The study included 182 patients with CTEPH in the long term after surgery. Depending on the Patient Health Questionnaire 9 ( PHQ-9) data, all patients were divided into 2 groups: the 1st group — patients without depressive syndrome in the long-term postoperative period, the 2nd — patients with depressive syndrome. A comparative assessment of the initial clinical and functional characteristics, as well as QoL was carried out using the SF-36 questionnaire in both groups of patients. In patients who had a coronavirus disease 2019 (COVID-19), a comparative assessment using the Post-COVID-19 Functional Status (PCFS) scale was carried out.

Results. Clinically relevant depressive syndrome in patients with CTEPH in the long term after surgery was registered in 25,3% of cases. In the 2nd group of patients, prior myocardial infarction (p=0,02), concomitant chronic cerebrovascular disease (p=0,01), as well as moderate and severe post-COVID-19 functional limitations according to the PCFS scale (p=0,004) were significantly more often recorded compared with the 1st group. In the 2nd group of patients, the level of QoL in almost all parameters was significantly lower in comparison with the 1st group (p<0,05). Decreased QoL (score <40) in the 2nd group concerned numerous parameters, including the physical and mental health components. In the 1st group of patients, reduced QoL was observed only in some physical parameters.

Conclusion. The group of patients with CTEPH with depressive syndrome in the long-term postoperative period was characterized by a higher incidence of concomitant chronic cerebrovascular disease and a history of myocardial infarction compared with patients without depressive disorders. In the group of patients with depressive disorders, moderate and severe post-COVID-19 functional limitations according to the PCFS scale were more often observed. Depressive disorders in patients with CTEPH in the long-term postoperative period were accompanied by significantly reduced QoL parameters. Patients experienced the greatest difficulties both during normal daily activities and in professional activities.

RESUMO Objetivo: avaliar a efetividade do índice de peritonite de Mannheim (IPM) para predizer mortalidade em pacientes com peritonite no Hospital Santa Casa de Misericórdia de Vitória (HSCMV). Método: Coorte longitudinal, observacional retrospectivo, com amostra de 75 pacientes diagnosticados com peritonite entre janeiro de 2010 a 02 de dezembro de 2015 no HSCMV, com todos os critérios necessários para o cálculo do IPM. Resultados: Encontrou-se um perfil dos pacientes, sendo 33 do sexo feminino e 42 do masculino, idade média de 42 anos, 11 óbitos e percentual de mortalidade de 14,67%. Comparando as variáveis do IPM em dois grupos (sobreviventes e falecidos), constatou-se que idade maior do que 50 anos, presença de malignidade e pacientes com disfunção de órgãos tiveram significância estatística para mortalidade, com p<0,05. O IPM variou entre 4 e 41 pontos, com média de 21,2 pontos. No entanto, entre os falecidos o escore variou de 23 a 41 pontos, com média de 32,8. Sendo assim, foi estabelecido o ponto de corte de 27 pontos através da avaliação do melhor valor do Índice Kappa de concordância, e através dele foram calculados: sensibilidade de 90,90% e especificidade de 78,13% através da curva ROC. Conclusão: Com base nesses resultados, foi visto que o IPM foi eficiente em estimar o risco de morte, sendo esse identificado quando o índice atinge valores = 27 pontos.

RESUMO Introdução: o nariz é o ponto central da face e vulnerável à ocorrência de câncer de pele não-melanoma (CPNM), com impacto potencial na aparência. O retalho frontal paramediano (RFPM) é considerado a melhor opção para o tratamento de defeitos extensos no nariz. O objetivo deste estudo é apresentar a experiência de um centro oncológico de referência no uso de RFPM para reconstrução nasal no tratamento do CPNM. Métodos: estudo retrospectivo foi desenvolvido através do levantamento de dados de prontuário de pacientes submetidos à reconstrução nasal com RFPM devido à CPNM no Instituto do Câncer do Estado de São Paulo (ICESP). Resultados: 111 pacientes foram identificados, a maioria idosos, com comorbidades e portadores de tumores iniciais (T1 e T2). O carcinoma basocelular (CBC) foi o tipo histológico predominante. Dorso e ponta foram as subunidades mais acometidas. Além da cobertura cutânea, em metade dos casos foi realizada também a reconstrução do forro ou arcabouço do nariz. Cicatrização por segunda intenção foi a técnica de escolha no fechamento da área doadora. A liberação do pedículo foi realizada predominantemente no segundo tempo cirúrgico e o tempo para finalização do tratamento teve mediana de 6 meses. Houve baixa taxa de complicações. Conclusões: o RFPM é seguro e eficaz no tratamento do CPNM nasal, mesmo em casos de elevada complexidade. O tempo total de tratamento pode ser prolongado e impactar na qualidade de vida, sendo fundamental enfatizar e discutir este aspecto com o paciente antes da cirurgia.

RESUMO Introdução: a recorrência da hérnia inguinal após hernioplastia varia de 0,5 a 15 por cento, dependendo do local da hérnia, tipo de reparo e circunstâncias clínicas. Muitos fatores de risco são conhecidos e devem ser considerados antes do procedimento. Acompanhamento e adequado bancos de dados são fundamentais para entender a incidência de recidiva. Métodos: estudo de coorte retrospectivo analisou hernioplastias inguinais realizados no Hospital de Clínicas de Porto Alegre entre 2013 e 2015. Para concluir 5 anos de seguimento, analisamos o prontuário e fizemos contato telefônico e por correio. Resultados: o total de 1094 registros médicos foram selecionados e um seguimento de pelo menos 5 anos foi possível em 454 pacientes - 538 reparos de hérnia inguinal devido à abordagem bilateral em 84 pacientes. Os pacientes responderam um questionário validado sobre sintomas de recorrência. A taxa total de recorrência foi de 9,29%. No grupo masculino, a recorrência foi de 10% contra 4% no grupo feminino. Para os pacientes com hérnia Nyhus IV, a recidiva foi de 24% contra 8% após o reparo da hérnia primária, com um risco de 2,8 maior. Não houve diferença na recorrência entre cirurgiões experientes e em treinamento. Conclusão: nossos dados revelam uma taxa de recorrência aceitável em um hospital de ensino, e para o nosso conhecimento é o primeiro artigo com acompanhamento de longo prazo no sul do Brasil. A re-recidiva da hérnia foi maior quando comparada com o reparo da hérnia primária.

Published: September 2022

RESUMO Introdução: teratoma sacrococcígeo é o tumor neonatal mais comum. Alfafetoproteína é um marcador tumoral importante e é utilizado no período de seguimento como um marcador de malignidade. A ressecção cirúrgica completa do tumor associado a coccigectomia é o tratamento padrão, associado a quimioterapia em determinados estadiamentos. Exames de seguimento consistem em avaliação de marcadores tumorais, investigação de sítios de metástases, além de um completo exame físico. Metodologia: foi realizado um estudo retrospectivo descritivo, através da análise de 25 pacientes em dois centros de referência em tratamento oncológico infantil, com teratoma sacrococcígeo no Estado do Rio de Janeiro, entre 2004 e 2019. Os dados clínicos e epidemiológicos foram descritos, comparando-se os dois centros. Resultados: as características socio-demográficas foram similares ao descrito na literatura médica. Os dados relativos ao tratamento e seguimento, como o uso de quimioterapia, uso de testes de imagem específicos, exame de toque e retal e seguimento ambulatorial, foi diferente entre os dois centros. Tivemos uma perda de seguimento de 25%. Conclusão: a característica de ser um centro não oncológico pode interferir com a aplicação do protocolo de tratamento de teratoma sacrococcígeo. O conhecimento dos dados estudados pode permitir a otimização da abordagem dos pacientes com esta patologia e gerar discussões sobre a aplicação integral dos protocolos terapêuticos em centros médicos que são qualificados para tal tratamento.

Abstract Lower limb ulcers secondary to chronic venous disease (CVD) are a significant public health problem in Brazil and account for about 70% of these ulcers. Despite recent technological advances and the various therapeutic options for treatment of these chronic injuries, several factors may be involved in resistance to treatment. Dystrophic calcinosis cutis (DCC) is a rare and often underdiagnosed condition that, when in conjunction with CVD, may be associated with a refractory healing process. In this article, we report a case of DCC in a patient with CVD and discuss its etiology, pathophysiology and possible treatment options.

Abstract Background Worldwide, peripheral arterial disease (PAD) is a disorder with high morbidity, affecting more than 200 million people. Objectives Our objective was to analyze surgical treatment for PAD provided on the Brazilian Public Healthcare System over 12 years using publicly available data. Methods The study was conducted with analysis of data available on the Brazilian Health Ministry’s database platform, assessing distributions of procedures and techniques over the years and their associated mortality and costs. Results A total of 129,424 procedures were analyzed (performed either for claudication or critical ischemia, proportion unknown). The vast majority of procedures were endovascular (65.49%) and this disproportion exhibited a rising trend (p<0.001). There were 3,306 in-hospital deaths (mortality of 2.55%), with lower mortality in the endovascular group (1.2% vs. 5.0%, p=0.008). The overall governmental expenditure on these procedures was U$ 238,010,096.51, and endovascular procedures were on average significantly more expensive than open surgery (U$ 1,932.27 vs. U$ 1,517.32; p=0.016). Conclusions Lower limb revascularizations were performed on the Brazilian Public Healthcare System with gradually increasing frequency from 2008 to 2019. Endovascular procedures were vastly more common and were associated with lower in-hospital mortality rates, but higher procedure costs.

ABSTRACT Climate change threatens the survival of commercial crops due to their narrow genetic base. One of the alternatives is the identification of plants with potential for abiotic stress tolerance. This study aimed to verify the physiological and anatomical adaptations to the drought period and the impacts on the yield of ‘Híbrido de Timor’ coffee tree accessions. The experimental design was randomized blocks, in a 7 x 2 factorial arrangement, being seven genotypes (UFV 377-21, UFV 377-21, UFV 442-42, BE 5 Wush-Wush x UFV 366-08, UFV 428-02, UFV 376-31 and UFV 427-55) and two seasonal periods (dry and rainy), with two replications. The stomatal conductance; predawn water potential; levels of hydrogen peroxide and malondialdehyde; activity of the enzymes catalase, superoxide dismutase and ascorbate oxidase; ascorbate content; cuticle thickness of the adaxial surface and leaf lamina; stomatal density; ratio between polar and equatorial diameter; phloem area; area, diameter and frequency of xylem vessels; relative hydraulic conductivity; vulnerability index; and yield were evaluated. The results showed acclimatization of the accessions to the dry period, with some of them maintaining higher water potential values in the predawn; induction of the antioxidant system with the increase in the activity of the superoxide dismutase enzyme and ascorbate levels; increase in the cuticle and leaf lamina thickness; and a higher ratio between polar and equatorial diameters. Most of the evaluated accessions showed a good productive performance, especially the ‘UFV 377-21’, ‘UFV 442-42’ and ‘UFV 376-31’, with adaptations to the dry period and yield potential.

ABSTRACT Using beneficial fungi and bacteria to plant growth may reduce the leaf nitrate content and improve the quality of produced food. This study aimed to evaluate the isolated and combined effect of inoculation with Azospirillum brasilense and Trichoderma hazianum at two electrical conductivities on the nutrition and production of hydroponic arugula cultivation. The experiment was designed in randomized blocks, in a 4 x 2 factorial scheme, with five replications. The treatments consisted of inoculations (non-inoculated, A. brasilense, T. harzianum and co-inoculation) and two electrical conductivities (1.4 and 1.6 dS m-1). The isolated inoculation of T. harzianum and A. brasilense produced a higher root fresh mass, while the leaf chlorophyll index was higher with the inoculation of A. brasilense, concerning the other treatments. The inoculation of A. brasilense reduced the nitrate content in the arugula leaves. The inoculations and co-inoculation of A. brasilense and T. harzianum improved the yield components and plant nutrition, reduced the leaf nitrate content and promoted the biofortification of arugula leaves with Zn and Fe. In addition, the inoculation with T. harzianum increased the P and S leaf content.

Abstract Introduction In stroke survivors, the prevalence of upper motor disability remains high. There has not been much report on the success of post-stroke mirror therapy, especially in developing countries. Objective The focus of this research is to see how mirror therapy, in addition to standard rehabilitation for hand paresis, affects upper limb motor recovery and level of independence in self-care after stroke at an Indonesian teaching hospital. Method This was a randomized controlled trial with no assessor blinding. The study included 18 subacute stroke patients who did not have cognitive or visual impairment. The mirror group received a 20-minute mirror therapy session in addition to conventional rehabilitation, while the control group received only the standard program for 5 weeks (2 times per week). The Brunnstrom score and self-care level of independence elements of the Functional Independence Measure (FIM) were used as outcome measures. Results Baseline comparisons of lesion type and Brunnstrom score showed significant between-group differences. The ANACOVA test showed the difference had no effect on the FIM change in scores (P > 0.05). One patient (mirror group) was dropped out from the study. After 5 weeks (n=17), the mirror group showed improvement in both the Brunnstrom and FIM scores (P < 0.05) compared to the control group. Conclusions Mirror treatment improves upper limb motor recovery and level of independence in self-care after stroke when combined with standard hand paresis rehabilitation 2 times a week for 5 weeks.

Abstract Preliminary results of a research that seeks to characterize the intervention model of an Intensive Outpatient Program for the treatment of drug and/or alcohol use in pregnant and maternity women of the CRS of the Hospital El Pino, in the commune of San Bernardo, Chile, are presented. The objective is to describe the characteristics of the accompaniment process with a gender approach carried out by the health team working in the program and to consider its transdisciplinary character as keys to improving adherence, reducing dropout rates, favoring therapeutic discharges, promoting autonomy and the exercise of rights. The methodological design corresponds to qualitative research with an emic and intracultural approach, which seeks the point of view within the team. The sample is purposive, and the information was produced through nine participative group interviews with the work teams and an individual semi-structured interview with the head of the program, carrying out a thematic analysis of the experiences shared. The results indicate that the accompaniments from a gender and human rights perspective favor transdisciplinary work, key aspects to reduce equity gaps, and favor access to health for women in vulnerable conditions. Being the occupational therapies from the south are important to enhance these processes.

Background: Among new therapies emerging in the medical field, the use of platelet-rich plasma (PRP) in human reproduction has not yet been explored. Platelet-rich plasma (PRP) has a potential effect on tissue repair through proliferation and differentiation of tissue progenitor cells. The aim of this study was to evaluate the effect of PRP on the testis structure and function in the rabbit model. Material and methods: A total of 30 male rabbits were recruited in this study. They were allocated into two groups (15 in each group) to receive an injection of PRP (PRP Group), or normal saline (Control Group) Results: there were statistically significant differences in Means of germinal layer width, Leydig cell number, and Sertoli cell number was significantly higher in the PRP group compared to that in the control group ( P ≤ 0.05). The PRP group had a higher means of sperm concentration and normal morphology compared with the control groups (P ≤ 0.05). Conclusion: the platelet-rich plasma is found to have a good potential effect on the testicular tissue that improved the histological and functional aspects and could be considered a promising future treatment for hypogonadism status in many disorders. Keywords: PRP, reproductive function, testis, Sertoli cells, Leydig cells, the height of the germinal layer KEY WORDS: Platelet-Rich Plasma (PRP), Tissue Progenitor Cells, Testis.
Lexical and functional adpositions: the view from of in Old and present-day English
Authors: Taylor Roxanne
Published: September 2022

This article addresses the distinction amongst adpositions between those adpositions which are lexical and those which are functional. The article uses a corpus linguistic approach to address outstanding questions: whether there are two distinct subclasses of adposition, whether the distinction is a continuum amongst adpositions, and how— by what properties— lexical and functional adpositions are distinguished. The article argues for a primarily semantic, multifaceted distinction amongst adpositions, best understood as a continuum. The distinction is argued to be quite small, such that lexical and functional adpositions are not strongly differentiated and an argument is made in support of the more functional status of adpositions generally. A “bottom up” approach is used, which builds from the observable differences between two adpositions, one lexical, and one functional, to characterizations about the nature of the lexical versus functional distinction amongst adpositions. The adpositions used as the basis for this approach are Old English ofOE and its present-day English counterpart ofPDE. Of in the history of English offers a uniquely ideal case-study for an investigation into lexical and functional adpositions, given the uncontroversial functional status of ofPDE and the accepted lexical status of ofOE. The article identifies differences between ofOE and ofPDE primarily in semantics, in the number of available semantic relations. Syntax, morphophonology, and the possible replacement of an adposition by case are found not to represent areas of major difference between the adpositions. Instead, there is continuity between the adpositions in syntax and semantics. The historical evidence provides an opportunity to explore the grammaticalization of an adposition from lexical to functional. The comparative findings have consequences for the retention of meaning in semantic expansion and contradict notions of coevolution between syntax and semantics in grammaticalization. The context-specific nature of grammaticalization is also questioned on the basis of the comparison between the adpositions.
Reflections on Educational Reforms: A Journey of Profound Awakening - In humble tribute to His Majesty Jigme Khesar Namgyel Wangchuck’s 42nd Birth Anniversary

A review of the literature reveals that education is undergoing radical change affecting both the organization of educational institutions and the content and delivery of the curriculum. Considerable interest is being shown in the reengineering and reinventing of education by leading thinkers and scholars worldwide. Leaders and managers in educational institutions are increasingly faced with the challenge of having to operate in a rapidly changing world and within new and uncertain frameworks. Terminologies such as "educational system", "educational reform" and "educational change" have distinct meanings and implications. Educational reform implies that the reform initiative is an attempt to correct a deficiency in the existing educational system without changing the essential elements of the system. Educational change is a socio-political transformative process of change resulting in an educational system significantly different from the one before the change initiative. In educational reform, most aspects of the educational system remain the same and are understood to be inherently a political process. For discussion purposes, these terminologies have been used interchangeably in this article.

Bhutanese science curriculum witnessed several rounds of reforms to improve the quality of science education. The growing body of research, however, reports that the Bhutanese science curriculum is affected largely by several issues and challenges. Therefore, an exploratory study was carried out to document the issues and challenges of the Bhutanese science curriculum. Twenty-one (N=21) Bhutanese science teachers took part in the study. Data were collected through one-on-one interviews. The data collected from interviews were analyzed based on thematic analysis. The findings suggested that the Bhutanese science curriculum is largely voluminous, content-laden, high in lexical density, or prescriptive. Moreover, findings also inferred that the Bhutanese science curriculum largely lacks scientific inquiry, logical progression, and developmental appropriateness of concepts, or attributes of contextualization. Overall, compared to the science from fourth to sixth grade, seventh to 12th-grade science appeared largely plagued by issues and challenges. Findings from this study have some practical implications for Bhutanese science teachers and science curriculum developers.
