Published: June 2021

Ibn Khaldun is an Islamic scholar with various works, especially in the muqaddimah book which explains the principles of taxation. According to Ibn Khaldun, the imposition of low taxes on the people will make the people more incentivized to do business and develop the business world. On the other hand, the imposition of high taxes on the people will be reluctant to pay taxes so that the production done by the people will decrease and affect the tax revenue itself. The purpose of this study was to determine the relationship between Ibn Khaldun's theory and the current downturn in economic growth. This research method is library research research with a descriptive qualitative approach with the data source used is secondary data consisting of the book "muqaddimah" and other theories derived from books, journals, and official websites that are relevant to the research. The data that has been collected is analyzed using the Content Analysis Method. This study concludes that Ibn Khaldun's thoughts are very relevant when applied in facing the recession in Indonesia.
Comparison of Local Recurrence Patterns of Postoperative Radiotherapy with Surgery Alone for Esophageal Carcinoma Patients
Authors: Xu Zhi-Chen , Su Bao-An
Published: June 2021

ABSTRACT

Background:

We analyzed local regional recurrence patterns of thoracic esophageal carcinoma after three-field lymph node dissection (3-FLD) with and without postoperative radiotherapy, and assessed the postoperative radiation value for local control.

Methods:

The study reviewed 239 local recurrences of esophageal squamous cell carcinoma after 3-FLD from 2010 to 2018 in our hospital, retrospectively, and compared local regional recurrence patterns between surgery followed by radiotherapy (S+RT) and surgery alone (SA).

Results:

In 239 thoracic esophageal carcinomas that underwent curative surgery, the lymph node recurrence was the most common type of local recurrence for patients in both groups. The sequence of lymph node recurrence rate in both groups from highest to lowest was mediastinal, cervical, and abdominal. The recurrence rate of superior mediastinal lymph node in patients without radiotherapy was significantly higher than that in patients with radiotherapy (67.72% vs. 47.54%, x2 = 7.615, P = 0.006). The recurrence rate of abdominal lymph node in the upper TEC was significantly lower than that in the middle and lower TEC (x2 = 9.452, P = 0.009). The abdominal lymph node recurrence rate in patients with preoperative abdominal LNM was very significantly higher than that in patients without preoperative abdominal LNM (43.63% vs. 6.66%, P < 0.001).

Conclusions:

The dangerous lymph node recurrence regions included superior, middle mediastinum, and neck. Postoperative radiotherapy shows great value for patients in reducing superior mediastinal lymph node recurrence rate. The lower segment of thoracic esophageal carcinoma and preoperative abdominal lymph node metastasis, especially para-aortic lymph node metastasis, may be risk factors for abdominal lymph node recurrence.

Authors: Aleksandrova Elena Sergeevna , Sytina Nadezhda Aleksandrovna
Published: June 2021

The research aims to identify gender-specific features of translating literary works at different levels of the language system. Scientific novelty lies in the fact that the authors have studied how the translator’s gender influences quality of translation into Russian of literary works that have not become an object of such an analysis yet. As a result, it is proved that gender specificity of O. Henry’s stories translations manifests itself at different levels of the language system. Nevertheless, one cannot say that there are some substantial differences regarding translation quality and adequacy which would suggest the gender dimension influence. This influence is mostly noted when carrying out a comparative analysis of certain translation techniques.

Published: June 2021

The article is devoted to studying linguistic representation of the CAUSALITY concept in the Buryat language. The paper describes the basic types of prototypical and non-prototypical causative constructions, reveals their structural peculiarities, specificity of linguistic representation. Scientific originality of the study lies in the fact that for the first time in the Buryat linguistics, the authors examine the syntactic category of CAUSALITY from the viewpoint of the prototypical approach. The research objective includes identifying the prototypical and non-prototypical constructions representing the concept CAUSALITY in the Buryat language. As a result, it is shown that in the Buryat language, the prototypical nucleus of the CAUSALITY concept includes constructions with the meaning of inducement or direct physical influence. These constructions include morphological and lexical causatives and polypredicative constructions. It is noted that in the Buryat language, polypredicative constructions serve exclusively to express prototypical causation.

Published: June 2021

Перспективные линии ярового рапса в питомнике конкурсного сортоиспытания изучали в 2019 г. в Акмолинской области Казахстана. Объем изучаемого материала составил 26 образцов, за стандарт принят местный сорт Майкудук. Осенне-зимних запасов влаги в почве было достаточно для оптимальных всходов, этот показатель колебался от 80 до 96 %. Погодные условия, сложившиеся в период вегетации рапса ярового, можно охарактеризовать как жёсткие. Наряду с засухой в 2019 г. наблюдалось большое нашествие вредителей, которые в своём большинстве превышали экономический порог вредоносности. В связи с этим были проведены агротехнические и химические мероприятия по сохранению рапса. Вегетационный период линий ярового рапса различался незначительно и находился в пределах 106 – 107 дней. На протяжении всего вегетационного периода образцы ярового рапса подвергались определённым рискам, но смогли сформировать урожайность от 6,0 до 8,14 ц/га. Наибольшую урожайность сформировала линия 18-10 — 8,14 ц/га. Масса 1000 семян колебалась от 3,30 (линия 7-10) до 7,10 г (линия 8 – 10). По ряду признаков выделились линии: дружность созревания — 15-10, 21-10, 37-10, 24-10, 18-10 и Майкудук; устойчивость к засухе — 7-10, 18-10, 32-10 и Майкудук, к полеганию — 24-10, 7-10, 18-10, 47-06, 5-10, 15-10, 21-10, 37-10 и Майкудук. Все эти линии представляют интерес для дальнейшей селекционной работы.

O estudo objetiva analisar as contribuições e limitações do processo de formação inicial, vivenciado por dois professores de Matemática, em fase inicial de carreira docente, no contexto da Universidade Estadual do Ceará – Campus Itaperi, evidenciando possibilidades e desafios na ação cotidiana dos docentes na etapa introdutória da profissão. Caracterizamos como professores de Matemática em início de carreira aqueles que possuem até cinco anos de experiência no âmbito profissional, em consonância com os estudos de Huberman (2000), que descreve as fases do ciclo vivencial docente. A formação inicial pode reverberar em aprendizagens e conhecimentos essenciais para o trabalho qualitativo do professor de Matemática em início de carreira, bem como repercutir na explicitação de um trabalho meramente técnico, pautado pela exposição oral de conteúdos curriculares, em uma visão que não aguça a curiosidade dos estudantes, vislumbrando o conhecimento matemático como algo estático, desprovido de significação e distanciado da vida dos educandos. A investigação está embasada na perspectiva qualitativa da pesquisa. Como método, utilizou-se o estudo de caso e o procedimento de coleta de dados utilizado foi a entrevista semiestruturada individual. A formação inicial deve ser vislumbrada e desenvolvida como fator vinculado ao futuro exercício docente, por parte dos licenciandos, em que o conjunto de ações, planejado e desenvolvido, nessa etapa possam problematizar estratégias e situações vividas no âmbito da profissão, oriundas das vivências formativas e do campo do Estágio, visando uma reflexão crítica na e sobre a prática, bem como o desenvolvimento do espírito colaborativo, objetivando ajuda mútua com foco no grupo de profissionais que compõem a escola, local de atuação do professor da educação básica.

O trabalho ora apresentado se concentra na área de História da Matemática, mais precisamente na História da Matemática do Islã medieval. Discutiremos informações levantadas sobre uma carta escrita por al-Biruni que diz respeito a Lei dos Senos na Trigonometria Triangular Esférica, trataremos de seu conteúdo e estrutura, bem como observaremos a forma de registro do conhecimento na tentativa de responder à pergunta que norteia a construção do presente artigo: o que pode se falar sobre a estrutura da carta escrita por al-Biruni e que aspectos observados na carta, podem nortear a construção de uma narrativa que se aproxime de uma perspectiva atualizada de registrar a História? Usaremos para o desenvolvimento do trabalho historiográfico uma tradução da carta que está em inglês e foi encontrada no livro Beyruni’ye Armagan, mais precisamente no capítulo intitulado Al Beyruni's Letter on Abu Nasr Mansur's Demonstration of the Sine Law que ocupa as páginas 183 a 197 e tem autoria do Dr. Aydin Sayli. No que diz respeito a carta, a original está em árabe e o livro supracitado consta, ainda, uma tradução turca. A partir do estudo da versão inglesa, em confronto com demais versões presentes no livro, verificamos que ela trata de seis casos da lei dos senos, diluídos em quatro demonstrações, os três primeiros casos são associados a Trigonometria Triangular Esférica (TTE) enquanto os últimos três, são associados a Geometria Plana. Assim, nosso objetivo é apresentar parte de uma análise historiográfica (ainda em desenvolvimento) e, pretendemos alcançá-lo pelo desenvolvimento desse trabalho que, mediante a questões metodológicas, se associa a uma pesquisa com abordagem qualitativa e de procedimentos documentais e bibliográficos. Como resultado, apresentamos uma apreciação preliminar da carta e possíveis apontamentos que podem nortear a construção de uma narrativa mais contextualizada sobre o documento.

Published: June 2021

A partir da tentativa de sanar alguns dos problemas que se fazem presentes no cenário educacional, em especial, na educação básica, muitas das universidades elaboram projetos e estratégias que visam ampliar a formação de docentes, seja a formação inicial ou a continuada. Dentre esses projetos, estão os cursos e minicursos de extensão universitária, que podem ser voltados para a docência. Nesse sentido, este estudo tem a intenção de apresentar alguns conceitos matemáticos, que foram mobilizados pelos cursistas durante o minicurso ministrado na XXV Semana Universitária, da Universidade Estadual do Ceará, no qual estudou-se o instrumento matemático para multiplicações, denominado Promptuario, presente na obra Rabdologiae, Seu Numerationis per Virgulas..., publicado em 1617 e de autoria de John Napier. Para tanto, valemo-nos da pesquisa participante no que se refere à aplicação do minicurso enquanto objeto de estudo, bem como utilizamos a pesquisa descritiva, em caráter qualitativo, além de estarmos amparados na proposta de interface entre história e ensino de Matemática. Alicerçados nisso, foi possível elencar e justificar os conhecimentos matemáticos que foram mencionados pelos cursistas nos relatórios de atividade e durante os encontros realizados, tanto aqueles que foram identificados tendo como base a leitura do documento original adotado quanto os que estavam sendo mobilizados durante o processo de construção física do Promptuario para multiplicação. Em suma, com a aplicação do minicurso, não só disponibilizamos novos conhecimentos e recursos para os discentes, como também compreendemos que esse instrumento pode ser incorporado em uma proposta de interface entre história e ensino de Matemática, a partir de uma vinculação do conhecimento matemático, que está presente na sua construção e utilização, junto ao processo histórico-contextual, em que esse conhecimento foi concebido.

A diagnostic dilemma and surgical attention of a giant broad ligament leiomyoma with cystic degeneration: case report
Authors: Yang Xiu-feng , Tang Meng , Liu Li-li , Wei Xiao-qiang
Published: June 2021

Background: Broad ligament leiomyoma is the most common extrauterine leiomyoma, but with a very low incidence rate. When broad ligament leiomyoma is giant and undergoes degeneration, it poses both clinical evaluation and radiological difficulty in differentiating from an ovarian tumor. Meanwhile the changes of anatomical structure increased the difficulty during surgery. Conclusions: Thus, the diagnosis of a cyst-solid complex adnexal mass with a marginally raised serum level of CA125 might be a broad ligament leiomyoma with degeneration besides a ovary tumor. During surgery of myomectomy, we should be meticulous hemostasis and avoid ureter and bladder injury and other complications.

Background: Chronic pelvic pain is a common complaint in the gynecological office. The association among anus levator muscle injury, CPP of unknown origin in parous women, and pelvic sensory symptoms have been demonstrated. The study’s purpose is to assess the intrarater/interrater reliability and agreement of pelvic floor biometry and levator ani muscle injury evaluated using three-dimensional ultrasound in women with chronic pelvic pain. Methods: Two raters independently and blindly acquired three datasets of three-dimensional transperineal ultrasound volumes. The datasets were evaluated 60 days apart. To assess levator ani muscle injury, the hiatal area/diameter, levator ani muscle thickness, urethra-anus distance, and levator-urethra gap were measured. The intrarater reproducibility and interrater reproducibility were calculated. The concordance correlation coefficients and limits of agreement were analyzed in 147 three-dimensional ultrasound volumes obtained from 49 patients. Results: Levator ani muscle injury was detected in 10.2% (n = 5/49), with a good intrarater concordance correlation of >0.90 for anteroposterior diameter, hiatal area, levator-urethra gap, and urethra-anus distance. The hiatal transverse diameter and levator ani muscle thickness presented poor correlation, with limits of agreement of 28.2% and 29.7%, respectively. The levator-urethra gap also presented poor interrater concordance. Overall, the interrater evaluation had moderate to substantial concordance. Discussion: In the detection of levator ani muscle injury in parous women, the hiatal anteroposterior diameter, hiatal area, and urethra-anus distance can be reliably assessed using three-dimensional transperineal ultrasound of the pelvic floor. However, owing to poor reliability, the hiatal transverse diameter, levator ani muscle thickness, and levator ani muscle-urethra gap require more studies before they can be applied clinically.
Uterine receptor activation in response to uterotonic agents in late-pregnancy rat myometrium following pretreatment with oxytocin: an in vitro study
Authors: Liao Li-Mei , Hu Jian-Ying , Wang Ting-Ting , Huang Shao-Qiang
Published: June 2021

Background: Long term exposure to oxytocin reduces the ability of myometrium to respond to oxytocin, leading to oxytocin receptor (OXTR) desensitization. In this study we analyzed the response to other uterotonics such as prostaglandin, as well as investigating prostaglandin E2 receptors (EP3) and prostaglandin F2α receptors (FP). We hypothesized that compensatory mechanisms would increase the expression and activation of FP and EP3 following OXTR desensitization. Methods: Myometrium from late-pregnancy rats was collected in order to assess mRNA expression levels for OXTR, FP, and EP3 using RT-PCR. This was done after 2 hours of pretreatment with 10-6 M oxytocin to induce OXTR desensitization, or equilibration in physiological salt solution (PSS). Myometrium was exposed to increasing concentrations of uterotonic agents (10-10 to 10-5 M) following 2 hours of pretreatment with 10-6 M oxytocin (experimental group) or with PSS (control group). Myometrium from the experimental group was washed with PSS and OXTR expression was assessed using Western blot and RT-PCR. Results: mRNA expression levels for EP3, FP and OXTR were not statistically different between the experimental (OXTR desensitization) and control groups. Compared to the control group, the (mean ± SD) contractile potency of carboprost (pEC50: 7.74 ± 0.56 vs 6.81 ± 0.25, P = 0.03) and maximal contractility of misoprostol (Emax(ratio): 4.44 ± 3.60 vs 1.32 ± 0.22, P = 0.02) were significantly increased in the OXTR desensitization group, while the contractility of oxytocin was significantly reduced (Emax(ratio): 1.62 ± 0.27 vs 2.82 ± 0.98, P = 0.015). No significant differences in myometrial OXTR expression were observed between the PSS, carboprost and misoprostol groups following OXTR desensitization. Discussion: Following OXTR desensitization of myometrium, FP and EP3 activation increased in a compensatory manner, but not FP and EP3 receptor expression.
The role of salivary progesterone and cervical length measurement in predicting risk of spontaneous preterm birth
Authors: Oday Sara , Sharief Maysoon
Published: June 2021

Background: Neonatal mortality and neonatal morbidity are increased by preterm birth. Researchers have assessed various biochemical and biophysical markers to predict women at risk for preterm birth in order to decrease its incidence, prevent complications and improve survival rate for infants. Objective: To evaluate the prediction of spontaneous preterm birth by estimation of salivary progesterone levels and by serial measurements of cervical length. Patients and methods: A prospective study was carried out at the Maternity and Child Hospital, Basrah, Iraq. Symptomless women (n = 40) with a single fetus, and with a preterm birth, preterm rupture of membranes, or late spontaneous miscarriage (at 20–28 weeks of pregnancy), were recruited from the outpatient clinic at 24–28 weeks of gestation and were retested after 4 weeks. At each visit, three salivary samples were collected and assessed for their progesterone level using ELISA. Transvaginal sonography was used for cervical length estimation. Results: Of the 40 women, 9 were delivered at term (i.e., after 37 weeks). Their mean pregnancy duration at time of parturition was (38 ± 2) weeks. The other 31 women underwent preterm birth, 13 cases with early preterm (≥24–34 weeks) and 18 cases with late preterm (>34–37 weeks). The mean levels of salivary progesterone for the term group at the first visit (24–28 weeks) and the 2nd visit (28–34 weeks) were 797.2 pg/mL and 899.4 pg/mL respectively. The mean levels of salivary progesterone in the preterm group at the first visit and 2nd visit were 344.2 pg/mL and 257.3 pg/mL respectively. The difference between the term and preterm birth groups was statistically significant (P = 0.04). There were significant differences regarding cervical length measurement between the preterm delivery groups and the term delivery group. Conclusion: Both low salivary progesterone concentrations and low cervical length can be applied for predicting preterm birth in asymptomatic at-risk women.
