A Pragmatic Analysis of Nelson Mandela’s Speech at Harvard University
Authors: Dharmendra Kumar Mishra
Published: May 2023

This article studies Nelson Mandela’s speech at Harvard University to understand his rhetorical skills. In this speech, he talks about how South Africans face disparities and injustice due to their race. He emphasizes the need for reconceptualization and redefining the economic system's precepts, which could benefit all regardless of race, gender, and ethnicity. The speech has been analyzed using Leech’s Maxims of Politeness and Aristotle’s Theory of Persuasion to investigate how rhetorical and politeness strategies have been used. The analysis shows that Mandela used Leech’s Maxims of Politeness as complementary to Aristotle’s strategies of persuasion to achieve desired communicative goals. He uses different strategies of logos and ethos to build a persuasive discourse. Besides, he uses modesty and approbation maxim and humour at the cost of self as the main strategies of politeness. Politeness complements his persuasive appeals and makes them more effective.
La lectura en el desarrollo de la personalidad: un ensayo de reflexión
Authors: Huiza-Soto Judith Amaranta
Published: May 2023

Uno de los objetivos fundamentales de la educación es formar y desarrollar la personalidad de los educandos para que puedan vivir en sociedad y triunfar en todos los campos de la actividad humana. Esta formación y desarrollo de la personalidad no pueden prescindir del desarrollo de las capacidades cognitivas, afectivas y conativas de la personalidad; por el que la lectura es un factor fundamental del desarrollo de dichas dimensiones. La lectura amplia, profundiza y eleva nuestro conocimiento de la realidad, convirtiendo nuestros conocimientos sensoriales y espontáneos en conocimientos racionales, sistemáticos, teóricos, científicos y filosóficos, no sólo para entender la naturaleza de nuestra realidad sino para dar sentido a nuestra producción e interacción social. Del mismo modo, desarrolla nuestra sensibilidad social, ética y estética, transfor- mando nuestras emociones psicológicas en sentimientos sociales, generando la comunión humana como condición fundamental de nuestro desarrollo; puesto que nadie puede desarrollarse al margen de la sociedad y en contra de ella. Y, finalmente, la lectura forma nuestra capacidad conativa enriqueciendo nuestros ideales por una vida mejor, por una sociedad más justa, por un futuro cualitativamente diferente y superior, inspirándonos a ser creativos e innovadores de nuestra realidad. Sin embargo, la comprensión lectora, ha sido estudiada sólo desde el punto de vista cognitivo como condición y capacidad imprescindible para lograr los aprendizajes significados en todo el proceso educativo. Razones por las cuales, en la presente ponencia, vamos a abordar la comprensión lectora como un factor que forma y desarrolla la personalidad en todas sus dimensiones.

The theory and practice of this convention are contrasted with the Chilean Seismic Design Code through three local architecture projects built within the 70’s decade and the year 2009. Finally, the significance of this convention is discussed, proposing a conceptual expansion of the Chilean building from an architectural perspective.
ACERCA DE LA ARQUITECTURA “NORMATIVA”. NOTAS ACERCA DEL DOMINIO DEL MODO TÉCNICO-RACIONAL DE PENSAMIENTO EN LA PRODUCCIÓN ARQUITECTÓNICA CONVENCIONAL: UNA REVISIÓN HISTÓRICA
Authors: Megahed Yasser
Published: May 2023

El concepto de pra?ctica “convencional” o “normativa” se utiliza frecuentemente para describir el modelo de pra?ctica de la arquitectura que suele ser gene?rica en sus ambiciones arquitecto?nicas y tiende a ajustarse a las reglas econo?micas del mercado. Este modelo de pra?ctica sigue lo que podri?a llamarse una “ideologi?a te?cnico-racional” que tiende a priorizar los discursos de eficiencia, verificacio?n y entrega rentable y opor- tuna. Este arti?culo resaltara? algunos de los momentos en la historia de la produccio?n arquitecto?nica que han pavimentado la vi?a para el predominio de la ideologi?a te?cnico-racional en la produccio?n arquitecto?nica contempora?nea, incorporando las ideas de Jean-Nicolas-Louis Durand y Leslie Martin, asi? como las que caracterizaron a la corriente de los Design Methods, todas las cuales influyeron en dar forma a la pra?ctica arquitecto?nica convencional. El arti?culo concluye con especulaciones acerca de la trayectoria futura de la profesio?n arquitecto?nica a la luz de la actual prevalencia de esta ideologi?a.
The Form of Conventions
Authors: Carrasco Purull Gonzalo
Published: May 2023

We lived in unconventional times, or at least that is what a sector of architectural practice believed, a sector that had been mainly focused on responding to the commissions, the needs, and the demands of an economic model that has driven architects into transforming their working conditions, favoring strategies that have adopted the ways of the generic and the standardized, while reaching a differentiation, socially acceptable, that allows them to achieve a certain distinction within the status quo determined by convention.

Published: May 2023

: This study aimed to determine the relationship between self-care and physician-patient relations in patients with Heart Failure (HF). This cross-sectional study was conducted on 200 patients with HF, referring to the outpatient clinics affiliated with Tabriz University of Medical Sciences, Iran. Utilizing a systematic random sampling method, the patients were selected from those who had made intake appointments. The Physician-Patient Relationship Questionnaire and the European Heart Failure Self-Care Behavior scale (EHFScB scale) were used to collect the data. Data were analyzed using descriptive statistics, Pearson correlation coefficient, logistic regression, Student’s t-test, and one-way ANOVA in SPSS (ver. 25). The total score of the self-care behaviors in the patients referring to the outpatient clinics was moderate (31.88 ± 8.66). Also, significant relationships were observed between the scores of self-care behaviors and physician’s gender, patient’s marital status, patient’s education, and between physician-patient relations scores and physician gender (P-value < 0.05). Moreover, physician-patient relations and marital status could predict the patient’s self-care variable by 22% (R2 = 0.221, F = 5.35). The study results revealed that physician-patient relations could explain the self-care behaviors of patients with HF.

Authors: Li Junying , Cao Peng , Liu Quanzhong , Yao Weifeng , Nie Zhenhua , Zhang Litao
Published: May 2023

Background: The evidence has shown the relationship between the microbiota of the face and several skin conditions. However, for rosacea patients, the changes in the facial skin microbiota still remain unknown. Objectives: This study was performed to explore the correlation between the facial skin microbiota and rosacea and analyze and characterize the facial skin microbiota of rosacea patients in comparison to healthy controls using 16S rDNA amplicon sequencing. Methods: A total of 27 rosacea patients and 25 healthy controls were matched. The DNA was extracted from participants’ skin swabs taken from the nose, chin, forehead, and bilateral cheeks. The V3V4 region of the 16S rRNA gene was sequenced using Illumina MiSeq technology. The diversity of the face skin microbiota was examined using alpha and beta diversity. Utilizing linear discriminant analysis effect size (LEfSe), the quantitative study of biomarkers in the two groups was carried out. Clusters of orthologous groups and Kyoto encyclopedia of genes and genomes function predictions were made at the genus level utilizing phylogenetic investigation of communities by reconstruction of unobserved states. Results: The alpha diversity of the facial skin microbiota increased significantly in rosacea patients, and beta diversity showed substantial differences between the rosacea and healthy control groups. The facial skin microbiota community structure changed in rosacea patients; however, the dominant strains were the same as in healthy controls, both being Propionibacterium acnes and Staphylococcus epidermidis. The LEfSe demonstrated that Xanthomonas, Acinetobacter, and Pseudomonas were enriched in the rosacea patients; nevertheless, Corynebacterium, Finegoldia, and Peptoniphilus were enriched in the healthy controls. The rosacea patients showed significantly decreased expression in the pathways of membrane transport, carbohydrate metabolism, metabolic diseases, amino acid transport and metabolism, carbohydrate transport and metabolism, transcription, and inorganic ion transport and metabolism. Conclusions: The facial skin microbiota diversity and community structure changed, and the expression of several metabolic pathways was downregulated in the rosacea patients in comparison to the healthy controls, which might outline new strategic methods for the surveillance, diagnosis, and treatment of rosacea.
Digital Image Analysis of Diabetic Foot Ulcer Areas Using ImageJ Software (National Institute of Health, USA) in Patients Treated with Autologous Activated Platelet-rich Plasma Injection
Authors: Fibrini Dewi , Lister I Nyoman Ehrich , Rosadi Imam
Published: May 2023

Background: In this cross-sectional study, we investigated three diabetic foot ulcer (DFU) patients. DFU is a serious diabetes complication affecting general health and social life. Autologous regenerative therapies, such as autologous activated platelet-rich plasma (aaPRP), have been proposed for DFU management. However, precise instruments are required to measure the wound size to evaluate wound closure after treatment. Objectives: This study aimed to evaluate the DFU healing process treated by aaPRP through digital image analysis using ImageJ software (National Institute of Health, USA). Methods: The DFU patients were administered aaPRP and followed up on days 7 and 14. The healing process was analyzed through ImageJ software. Paired t-test was used to assess the wound healing process. Results: The results showed that ImageJ was useful for wound area measurement. Granulation and sloughy tissue development can be evaluated and calculated as a part of wound healing progress. Conclusions: We conclude that ImageJ facilitates DFU analysis not only about the size but also on the healing time process through visualization of granulation and sloughy tissue formation, which can represent the healing progress.

Published: May 2023

Background: To date, multiple outbreaks of coronavirus disease 2019 (COVID-19) have been reported. Moreover, a wide spectrum of multiple organ involvements has been reported. Objectives: This study aimed to describe and compare the clinical characteristics, laboratory features, and outcomes of pediatric patients with COVID-19 and Multisystem Inflammatory Syndrome of Children (MIS-C). Methods: This cohort retrospective study was performed on patients under 18 years admitted with a diagnosis of COVID-19 and MIS-C in a pediatric referral center in the northwest of Iran from March 2020 to June 2021. This study included the data obtained from three time points, including on admission, 1 week, and 3 months after admission. Results: In this study, 151 patients with a mean age of 5.3 ± 4.1 years were enrolled, out of whom 51.7% and 48.3% were in COVID-19 and MIS-C groups, respectively. Fever was observed in 64.9% of the patients. In the third-month follow-up, there was no abnormality in the neurologic, respiratory, or gastrointestinal systems. For most patients with cardiovascular involvement, normal ventricular and valvar function, and coronary arteries were obtained in follow-up. Approximately one-third of the subjects were admitted to the pediatric intensive care unit (PICU). Neonates, those with cardiac involvement and underlying disease, were at a higher risk for PICU admission (P < 0.001). Moreover, six patients died. Conclusions: Although irreversible post-COVID-19 organ involvement is uncommon among pediatric patients, routine and preplanned follow-up programs play an important role in achieving satisfactory outcomes.

Authors: Heydarikhayat Nastaran , Ashktorab Tahereh , Zayeri Farid , Rohani Camelia
Published: May 2023

Background: Mental health is a serious concern for burn survivors. Burn injuries can bring long-term complications that begin at the moment of injury and last throughout a burn victim’s life. Objectives: This study aimed to determine the effectiveness of a home care plan in the mental health status of burn survivors six months after hospital discharge. Methods: This randomized clinical trial with intervention and control groups was conducted in Kermanshah, Iran. Eligible samples (n = 90) were allocated into the two groups by a randomized block design. The intervention group received a home care plan for six months. The General Health Questionnaire-28 (GHQ-28) was responded to by the samples at three time points, baseline (T1: hospital discharge) and 3 (T2), and six months (T3) after the intervention. Results: The mean scores of the GHQ-28 showed a descending trend in the intervention group during six months (T1: 32.48 ± 15.83, T2: 25.15 ± 15.11, and T3: 19.37 ± 14.11). However, the mean scores of the GHQ-28 were increased in the control group (T1: 32.29 ± 17.66, T2: 39.35 ± 14.59, and T3: 40.44 ± 15.59). There were significant differences between the two groups in 3- and 6-month measurements (P < 0.001). Conclusions: A 6-month home care plan improved the mental health of burn survivors in the intervention group in comparison to the controls; nevertheless, there were still survivors who needed help. Therefore, it is suggested to develop a home care plan with longer regular follow-ups for burn survivors based on their needs in the healthcare system of Iran.

The corrosion inhibition efficiencies of 39 Schiff’s bases of series from aniline, ethylendiamine, cyclohexylamine and 4,4-benzidine in the 1M and 2M HCl solutions on the steel (CT-3) and aluminium (D16) have been studied. It seems that the azomethine compounds with aldehyde moieties of 3-indolyl group (B8, C8 and H8) strongly inhibited the corrosion on aluminium but the corrosion inhibition effects on steel are relatively low. The azomethine compounds with aldehyde moieties of p-nitrophenyl group (B1, C1 and H1) inhibited highly the corrosion of both steel and aluminium in HCl solution. The bis-(4-nitrobenzylidene) diethylamine (B1) compound can be used as a good corrosion inhibitor for low carbon steel and aluminium in HCl acid solution.

Predicting atmospheric corrosion rate of metals has important practical significance. The linear model was often used to predict corrosion rate of metals but this provides low precision. This is because the influence of environmental factors to the corrosion rate is not linear. This paper presents the result of building up one artificial neural network using Matlab software, which can predict atmospheric corrosion rate of CT3 carbon steel in Vietnam tropical climate with input and output data of 26 test areas in 15 provinces of the North, Central and South of Vietnam. This neural network has 05 input parameters including the temperature, humidity, time of wetness - TOW, Cl- concentration, number of hours of rain (average of one year). The obtained results of corrosion rate of CT3 steel at 03 locations (Yen Bai, Da Nang, Thai Binh) by using the neural network show much higher accuracy (relative error < 30%) compared with the linear regression models.

During the period from 2007 to 2010, the reproductive disorders of women migrated from the North to Agent Orange sprayed regions of Tay Nguyen Highland and the health status of their F1 generation were investigated. The subjects aged 35- 54 were divided into 2 groups: The high-risk exposure group (n = 353) consisting of the women who were younger than 21 years and migrated to the sprayed regions before 1990; the low-risk exposure group (n = 477) consisting of the women aged 21 or older and have migrated since 1990. The controls (n = 1116) were the women living in the immigrant’s homelands in the North. The study results showed that: Spontaneous abortion/ stillbirth rates and mortalities among F1 generation of the exposure groups were higher than that of the controls, but no high Dioxin level was found in all environmental and food samples collected from the studied regions. Dioxin levels in environment and human tissues are now being monitored in order to obtain the actual level of exposure to Agent Orange.

Persistent infection with oncogenic human papillomavirus (HPV) genotypes has been shown to be necessary for the development of cervical cancer. The recently developed AMPLISENS® HPV HCR GENOTYPE-FRT assay (HPV Amp-genotype assay) is based on simultaneous PCR (multiplex - PCR) and Real-time to detect 12 HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) and β-globin gene, used as internal control, in 4 tubes. Each HPV type is registered on its channel, that allows not only to detect the presence of HPV DNA, but also to differentitate the virus genotype. The aim of this study was to evaluate the performance of the HPV Amp- genotype assay for detecting HPV genotypes and comparing the results with those obtained in combination of the AmpliSens® HPV HCR screen-titre-FRT PCR 4x (HPV Amp-screen assay), LightPower HPV Genotype PCR-HPV GENOTYPE RDB (HPV GENOTYPE RDB assay) and Kit LightPower iVAHPV PCR Plus assay (PCR plus assay). We found high similarity between HPV Amp-genotype assay and others (88,09% - 86,6%- 89,55%; Cohen’s kappa coefficients = 0,745- 0,698-0,734). The limit of detection of HPV Amp-genotype assay was 1,14.103 copies/ml, it was more sensitive than other assays. In conclusion, the HPV Amp-genotype assay is an alternative test for HPV genotyping in clinical laboratories.

Acinetobacter baumannii is one of leading causes of nosocomial infection. The bacteria possess instrinsic OXA-51-like gene. Moreover, with this gene the bacteria could resist to many antibiotics.The study aims to develop a real-time PCR protocol to detect intrinsic OXA-51-like gene in A. baumannii. The real-time PCR has been optimized with DNA-binding dye (EvaGreen) for amplifying OXA-51-like gene specific to A. baumannii and 16S rRNA gene specific to Acinetobacter spp. in one reaction. The protocol after setup was applied with several A. baumannii DNA samples. The result shows that the real-time PCR protocol can correctly detect intrinsic OXA-51-like gene in A. baumannii with the sensitivity of 32 copies/reaction and high specificity. The ratio of A. baumannii detection reached 100% for DNA samples which A. baumannii had been detected. The real-time PCR protocol using EvaGreen to detect OXA-51-like gene in A. baumannii has been developed successfully. The protocol can be used to rapidly detect A. baumannii based on this gene.

In the present study, six strains of yeast were isolated from the broken PPU foam, which has been used in Su-30 MK2 aircraft for 6 years at Bien Hoa airport. Strain BHH3 was determined as a yeast candidate capable of producing polyurethanase and urease to break down PPU. In liquid mineral medium supplemented with PPU as the only carbon and energy sources, the strain BHH3 grew and attached to the PPU foam surface, and changed its colour from light yellow to brown just after 7 days at 30C. After 28 days testing, the tensile strength and elongation at break in the PPU foam was reduced significantly, reaching 11.8N/m2 and 249%, in comparison with that of the control of 12.6 N/m2 and 335%, respectively.
