Algunos problemas del marxismo
Authors:   Universidad Autónoma de Zacatecas, Veltmeyer Henry
Published: April 2021

This article examines three key concepts in the analysis of the problems of capitalist development in the first two decades of the 21st Century. First, extractivist capitalism or capitalist development in its extractivist form, which refers to the advance of capital invested in the acquisition of land and the extraction of natural resources for export in primary commodity form. Second, the debate around the theory of value-labor that has assumed renewed strength in the context of the advances of extractive capital as part of the development of productive forces. Third, the concept of superexploitation advanced by Ruy Marini, with reference to mechanisms that allow for the remuneration of labor on the periphery of the world system at a level below the value (the value of labor power, the commodity that workers seek to exchange against capital for a living wage). Fourth, the formation of a global reserve army of intellectual labor, qualified to participate in the construction of scientific knowledge concentrated in centers of technological innovation. Finally, the article addresses the dynamics of productive and social transformation that accompanies each advance of capital in the development process.
Strategies to Help Students Solve Addition and Subtraction Word Problems
Authors: Peltier Corey , Hott Brittany L. , VanDerHeyden Amanda
Published: April 2021

Word problem solving is a difficult task that requires students to decode and comprehend written text, activate prior knowledge related to the mathematical problem presented, devise a plan and execute that plan to yield a solution, and contextualize the solution. One intervention with considerable research evidence supporting its use is schema-based instruction. Schema-based instruction is an intervention specifically focused on teaching students how to identify the underlying structure of a word problem to facilitate an appropriate solution plan. The purpose of this article is to explain and demonstrate how to implement schema-based instruction to help students solve additive word problem structures.
Tendencias en el análisis estadístico: Límites de la inferencia frecuencial y posibilidades del enfoque bayesiano
Authors: Bologna Eduardo
Published: April 2021

Statistical procedures used in psychological research are in full review. The accumulation of criticism upon classical techniques has led to different answers. On one hand, there is a deepening on pushing analysis beyond hypothesis testing and more elaborate interpretation of data. On the other hand, more and more researchers suggest introducing Bayesian approach to make inferences, and there are more software routines to facilitate this. On the frequentist approach, this paper discusses additional procedures to test hypotheses suggested in the sixth edition APA Publication Manual. We review the rationale of hypothesis testing; we show the usefulness of reporting effect size measures ―and the difficulty to infer about them―, power analysis, and the different alternatives to calculate confidence intervals. On the Bayesian approach, we discuss the assumptions and the advantages in terms of information it offers and its contribution to the cumulative nature of the results. Then we show a simple illustrative application of its rationale, comparing the estimation of proportions by means of credibility and confidence intervals.
Evaluación psicométrica de la Escala de Resiliencia para niños mexicanos (GA-RE14)
Authors: González-Arratia-López-Fuentes Norma Ivonne , Domínguez-Espinosa Alejandra del Carmen , Torres Muñoz Martha Adelina
Published: April 2021

The psychometric properties of the short version of González-Arratia’s Resilience Scale for children (GARE14) are examined through two studies. The first one analyzes the three-dimensional structure and internal reliability of a 217 children sample with both genders (122 boys, 95 girls) with an average age of 11.14 (SD = .78). Study 2 presents evidence of theoretical convergence with self-esteem and satisfaction with life, with 121 participants (59 boys, 62 girls) aged 9 to 12 years old (M = 10.60, SD = .67). The configuration is verified by using confirmatory factorial analysis (GFI = .94, AGFI = .91, RMSEA = .046; NFI = .79, TLI = .90, CFI = .92). A significant positive association between the evaluated variables, and higher scores in girls than in boys are reported. This scale is useful for the measurement of resilience in children, for academic contexts and for research purposes.
El factor p. ¿La estructura subyacente a la psicopatología?
Authors: Montes Silvana Andrea , Sanchez Roberto Oscar
Published: April 2021

Psychopathology is in a moment of crisis. The categorical classification systems have received several criticisms from researchers and clinicians. New proposals try to present a superior, dimensional and hierarchical model. Among them are those that propose a single dimension of general psychopathology. In this study, we sought to analyze the underlying structure of pathological personality traits, looking to provide evidence for such proposals. In doing so, the internal structure of the Spanish version of the Personality Inventory for the DSM-5 [PID-5] was examined by a confirmatory factor analysis. Four alternative models were compared: the five-factor model, a second-ordered factor model, bifactor, and one-factor. The bifactor model presented a better fit to the data. This suggests that the observed variables reflect five specific pathological traits but also a general propensity for psychopathology.
Desarrollo y validación de la Escala de Percepción de la Infidelidad en las Redes Sociales
Authors: López-Figueroa Gladiminet , González-Rivera Juan Aníbal
Published: April 2021

The purpose of this study was to develop and validate the Perception of Infidelity in Social Networks Scale. A total of 300 Puerto Rican adults participated in this psychometric study. The sample was selected by availability. The results confirmed that the scale has a one-dimensional structure. A total of 12 items complied with the criteria of discrimination and presented appropriate factor loadings. The reliability index for the final version was .98 (Cronbach’s alpha). These results suggest that the Perception of Infidelity in Social Networks Scale has the potential to measure this construct among Puerto Rican adults. Likewise, the scale will advance further research of cyber-infidelity in Puerto Rican and Latin American couples.
Desarrollo de instrumentos para medir actitudes hacia la comunidad trans: Análisis preliminares
Authors: Esteban Caleb , González-Rivera Juan Aníbal , Francia-Martínez Margarita , Lespier Zahira
Published: April 2021

The purpose of this study was to develop and preliminarily validate two instruments to measure attitudes of psychotherapists towards the trans community. The former instrument measures the attitudes of psychotherapists towards the transgender community and the latter, towards the transsexual community. The sample consisted of 131 participants recruited according to their availability. The results preliminarily confirmed that both scales have a one-dimensional structure. Cronbach’s alpha internal consistency index for the first scale was .75 and .85 for the second. There were no significant differences in attitudes towards the transgender and transsexual community between students and psychology professionals. We conclude that the health of trans people is a human and universal right, therefore, it is the responsibility of all psychotherapists to educate themselves about the issue and it is a debt of the educational institutions to integrate it into their curriculum.

Published: April 2021

The objective of this work is to present the validation of an instrument to measure the psychological adaptation in parents to a disease or genetic risk in their children: Psychological Adaptation Scale to Genetic Counseling. A methodological study was carried out, with a sample of 203 cases. Construct validity was studied by a parallel analysis and an exploratory factor analysis. The significance of the Bartlett sphericity test (χ2 (105) = 1928.4; p < .001) was significant and the Kaiser-Meyer-Olkin (KMO) sample adequacy index indicated an adequacy of .87. A single factor was obtained that explained 45% of the variance. Reliability was studied using the Cronbach’s alpha coefficient, finding a high value of internal consistency α = .915. The present study offers the first valid and reliable instrument in Spanish to measure, in parents, their psychological adaptation to a disease or genetic risk in their children.

Horacio J. A. Rimoldi (1913-2006)
Authors: Evaluar Revista
Published: April 2021

El 19 de enero de este año nos ha dejado el Dr. Horacio Rimoldi. Para quienes tuvimos la suerte de estudiar y trabajar a su lado ha sido una enorme pérdida. Nacido en Buenos Aires, desde muy joven manifestó dotes extraordinarias para la ciencia. Discípulo del Dr. Bernardo Houssay se formó en la Facultad de Medicina de la Universidad de Buenos Aires. Viajó luego a Inglaterra con una beca del British Council para estudiar psicología en Oxford con Stephenson, un discípulo de Spearman con quien aprendió psicometría. Invitado para enseñar Psicología en la Facultad de Filosofía y Letras de la Universidad Nacional de Cuyo (recién creada en Mendoza) organizó un Instituto de Psicología Experimental. Allí se formaron algunos investigadores, entre los que me cuento, realizando las primeras estandarizaciones de tests que fueron trabajos pioneros en América Latina. En 1946 el Dr. Rimoldi obtuvo la beca Guggenheim y se trasladó a Chicago en donde estudio y trabajó al lado de Thurstone. Pasó así 25 años en los Estados Unidos, creó un Instituto de Psicología en la Universidad de Loyola de Chicago y realizó allí una obra muy extensa y prolífica dejando un grupo de alumnos que han seguido sus trabajos muy de cerca. Durante ese tiempo publicó innumerables trabajos y se relacionó muy estrechamente con algunos de los psicólogos más importantes de su época como Gordon Allport, Edwing Boring y Wolfgang Kohler. Ya en 1955, muy al comienzo de lo que hoy se considera psicología cognitiva publicó un trabajo sobre “resolución de problemas” que tuvo gran repercusión.

Avances metodológicos en evaluación de emociones positivas en niños en risesgo social
Authors: Oros Laura B.
Published: April 2021

El presente trabajo tiene como propósito revelar algunas propuestas para sortear las dificultades que suscita la evaluación en niños escolares en riesgo por pobreza extrema. Por las características propias de este grupo social (desnutrición, pobreza de lenguaje, baja estimulación y déficit cognitivos como consecuencia de los puntos anteriores), la tarea diagnóstica se vuelve un procedimiento lento y costoso. En el marco del Programa “Sin afecto no se aprende ni se crece”, se pusieron a prueba las versiones preliminares de diferentes escalas para evaluar cinco emociones positivas. Participaron escolares, de entre 6 y 7 años de edad, que concurrían a una escuela urbano marginal, ubicada en la localidad de Paraná, en la provincia de Entre Ríos. Se comparte el proceso de evolución y sustitución de algunos indicadores psicométricos de emociones positivas haciendo referencia a la importancia de adaptar métodos y técnicas de exploración diagnóstica a las características de la población objeto de estudio.
Aprendizaje de la lectura. Diferencias entre escuelas de gestión pública y de gestión privada.
Authors: Urquijo Sebastián
Published: April 2021

El objetivo de este trabajo es el de evaluar, analizar y comparar los niveles de aprendizaje de la lectura considerando especialmente las diferencias en función del tipo de escuela al que asisten, basados en la existencia de diferencias de nivel socio-económico y cultural. Para ello, se evaluaron 610 niños, alumnos de los primeros tres años del ciclo básico de la educación primaria de 8 escuelas públicas y 4 escuelas privadas de la ciudad de Mar del Plata, Argentina, a quienes se les administró una versión adaptada del PROLEC para determinar sus desempeños en identificación de letras, procesos léxicos, procesos sintácticos y procesos semánticos. Los resultados indican, de forma sistemática en los tres años, diferencias estadísticamente significativas en la mayoría de las variables evaluadas, relacionándose de forma particular con las características del aprendizaje de la lectura en cada uno de los tres primeros años escolares. Las conclusiones discuten las posibles causas y las implicancias sociales de estos resultados.

Authors: Arana Fernán G. , Keegan Eduardo , Rutsztein Guillermina
Published: April 2021

El presente trabajo explora las propiedades psicométricas de la escala Almost Perfect Scale-Revised (APS-R) en una muestra de estudiantes universitarios argentinos (N=268). Se estableció el poder de discriminación de los reactivos y luego se realizó un análisis de la estructura factorial y consistencia interna. Se obtuvieron evidencias externas de validez. La primera cohorte (n=168) completó la APS-R junto a un cuestionario sociodemográfico, mientras que la segunda (n=100) completó también una medida autoadministrada acerca del promedio académico. Resultados. Los coeficientes de discriminación resultaron aceptables. Los niveles de consistencia interna fueron adecuados y se conservó la estructura factorial de la escala original: 3 factores explicaron el 53,35% de la varianza. Se encontraron diferencias de género para dos subescalas, mas no se encontraron resultados significativos en relación al promedio académico. Los resultados permiten apoyar adecuadamente la estructura factorial del perfeccionismo desadaptativo. Se discute el alcance de los resultados.
A study on differentiation of depiction between scatterer and reflector to assist epidural anesthesia by ultrasound
Authors: Hashimoto Takumi , Mori Shohei , Arakawa Mototaka , Onishi Eiko , Yamauchi Masanori , Kanai Hiroshi
Published: April 2021

A sharp depiction of the puncture point of the needle by differentiating muscle and bone is required for ultrasound-guided epidural anesthesia in the thoracic spine. In the present paper, we proposed a method for depicting the thoracic vertebral surface by utilizing the difference between scattering and reflection characteristics. This method estimates whether an object is a scatterer or a reflector referring to the scattering and reflection characteristics acquired in the water tank experiment. The proposed method was applied to basic experiments and in vivo experiments. In the basic experiments, the matching using root mean squared error allowed us to differentiate the depiction between scattering and reflection. In the in vivo experiment, we were able to estimate the position of the bone as a reflector and the slope was generally correct.
Design and realization of a weak magnetic fast electric heating chip
Authors: Guo Qi , Li Zhonghao , Zhao Rui , Wen Huanfei , Guo Hao , Tang Jun , Liu Jun
Published: April 2021

In a high-sensitivity atomic magnetometer, increasing the temperature of the vapor cell causes higher polarized atomic density, which enhances the intensity of the output signal. Therefore, it is essential to precisely control the temperature of the vapor cell. Based on the principle of electric heating and reverse magnetic cancellation, miniature weak magnetic electric heating chips of single-layer and double-layer structure are designed. By measuring the magnetic flux density at different distances and currents, it can be proved that the chips suppress the magnetic field. The experiment results show that the double-layer chip is better than the single-layer chip in respect of magnetic suppression and temperature response. The magnetic flux density introduced by the current at 5 mm from the chip is 0.0722 nT mA−1. These results show that a high-precision heating method for the atomic vapor cell can be realized by the double-layer meander structure, which provides a simple and fast electric heating scheme for atomic polarization.

Comparative methods for the quantification of post-IMA myocardial damage
Authors: Maiello Vincenzo , Iacono Maria , Cangiano Valerio , Calligari Dalila , Scarfato Emma , Stile Stefania , Cecere Claudio , Frasca Carmine
Published: April 2021

This work aims to make a comparison between laboratory methods, especially by evaluating the role of troponin dosage and diagnostic imaging methods, specifically SPECT and cardiac magnetic resonance in the post-IMA evaluation. In both methods, we want to understand which one is able to be more predictive in terms of quantifying the extension of the infarcted area. Given the high sensitivity of troponin, even a very small damage can result from this examination, which SPECT or MRI cannot do. It must be said, however, that the initial high sensitivity troponin is not predictive of how much ischemic damage will be but is only useful for prognosis. The objective of the study was to determine the feasibility and diagnostic accuracy of an RMC stress protocol with the combined assessment of regional myocardial perfusion and contractility in the recognition of patients with significant coronary atherosclerotic disease leading to AMI, correlating the results with what would have been the study in SPECT.

Authors: Srivastava Vipul K. , Khanna Rahul , Meena Ramniwas , Khanna Siddharth , Singh Chandradeep , Roy Shilpi
Published: April 2021

Introduction: Acute Pancreatitis (AP) is a potentially life threatening disease with varying severity of presentation from mild pain to persistent
organ failure. D-dimer is an indirect measure of brin degradation products. It is a stable molecule with half-life of 4-8 hours.
Material &Method: This is a prospective study done on 60 patients of acute pancreatitis treated at Department of General Surgery, Sir Sunderlal
Hospital IMS BHU Varanasi, UPfrom the period of 2016 to 2018. Patients with diagnosis of APas per revised Atlanta classication were taken and
D-dimer level was assessed at the time of presentation and patients were followed to assess the severity of disease and outcome. The D-dimer
values were correlated with the Glasgow-Imrie score as well as the CTseverity index (CTSI)
Result: Median value of D-dimer was found to be 3.68 mg/IFEU among the cases and 0.3 mg/IFEU among healthy volunteers. D-dimer levels
increased as per CTSI severity score ranging from 2.97 to >5.70 mg/IFEU along with increased mortality in patients whom D-dimer levels were
found to be high. D-dimer also showed positive correlation with Glasgow–Imrie score.
Conclusion: Determining the serum concentration of D-dimer on day of admission is helpful in earlier prediction and assessment of severity of AP.
ESTIMATION OF FETAL WEIGHT BY CLINICAL METHODS AND ULTRASOUND AND CORRELATING ITS ACCURACY WITH ACTUAL BIRTH WEIGHT IN TERM PREGNANCIES AT ANMMCH, GAYA, BIHAR
Authors: Ragini Kumari , Kumar Amit , Kumari Reena , Jana Debarshi
Published: April 2021

Objective:This study was to estimate the fetal weight in term pregnancy by clinical methods and ultrasound and to compare the results with actual
birth weight (ABW).
Material and Methods:This study was conducted at Department of Obstetrics and Gynaecology, Anugrah Narayan Magadh Medical College and
Hospital, Gaya, Bihar from December 2019 to May 2020. It was a prospective study covering 200 pregnant women at term gestation.
Results: Estimated birth weight by abdominal girth × symphysis fundal height (AG × SFH) formula was closest to the ABW (P = 0.060), as
compared to the estimated birth weight by Johnson's formula (P = 0.000) and Hadlock's formula (P = 0.000). Therefore, of the three formulae
studied, AG × SFH formula had better predictive value as compared to Johnson's and Hadlock's formulae. The accuracy of AG × SFH (Insler's
formula) for estimating the fetal weight at term was found to be comparable to Hadlock's formula (P= 0.104).
Conclusion: Clinical estimation of birth weight denitely has a role in the management of labor and delivery. AG × SFH is a simple, easy, costeffective, and universally applicable method to predict fetal birth weight which can be used even by paramedics like midwives and also in centers
where ultrasound is not available.
EVALUATE THE RELATION BETWEEN THYROID DISORDERS AND ABNORMAL UTERINE BLEEDING IN REPRODUCTIVE AGE GROUP : A CROSS SECTIONAL STUDY AT ANMMCH, GAYA, BIHAR
Authors: Ragini Kumari , Sourav Kumar , Diwedi Lata Shukla , Jana Debarshi
Published: April 2021

Introduction: Abnormal uterine bleeding (AUB) is a common disorder occurring in reproductive age group females. It can be understood as
bleeding that occurs from the uterus outside the normal parameters and there is no structural defects in the genital tract. One of the most common
association with AUB is thyroid dysfunctions. Hence this study aimed to see the incidence of thyroid related disorders in AUB and also to assess the
menstrual pattern.
Material and Methods: 100 women suffering from AUB who presented to OPD of Obstetrics and Gynecology department of Anugrah Narayan
Magadh Medical College and Hospital, Gaya, Bihar were recruited in the study. All females in 19 to 45 years of age group with abnormal uterine
bleeding were included excluding those with previously known thyroid disorder, abortion history within 3 months etc. Thyroid function tests were
done in all along with ultrasonography of pelvis region. Statistical analysis done.
Results: The bleeding abnormality that was found in the most of the women was heavy menstrual bleeding. Women who presented with thyroid
dysfunction were 33%. 23% had subclinical hypothyroidism, 6% had hypothyroidism and 4% had hyperthyroidism.
Conclusion: Abnormal Uterine Bleeding has strong association with thyroid disorders. Most common type of disorder is subclinical
hypothyroidism. Thus all patient of AUB must be evaluated for thyroid dysfunction

Published: April 2021

Diabetes has become a widespread epidemic, characterized by hyperglycemia resulting from an error in insulin secretion, insulin action, or both,
and is one of the leading causes of mortality and morbidity worldwide. Studies reveal that diabetes is linked to long-term complications in the brain,
which appear in the form of impaired cognitive ability compared to people without diabetes( Van Duinkerken et al 2020). Reduced physical
performance is one of the most important problems faced by patients which has a direct relationship with an individual's cognitive ability. The study
aims to analyse the direct and positive relationship between physical exercise and cognitive functions among people with type 2 diabetes, so this
must be veried along with gaining a comprehensive understanding of cognitive impairment in diabetes and its effect on physical performance.
vice versa. This study is based on the reviewed research results of various researchers. In this study, the term "cognitive impairment" in relation to
diabetes refers to any deviation in cognitive performance compared to people without diabetes.

Beta -HCG value more than 50Miu/dL.
Multi-core synthesis and maximum satisfiability applied to optimal sizing of solar photovoltaic systems
Authors: Trindade Alessandro , Galvão Edilson , Cordeiro Lucas
Published: April 2021

Annual global energy consumption growth is around 1.3% with forecasts until 2040. Photovoltaic systems became a suitable alternative to nuclear and fossil energy generation. In order to support this technology's dissemination, we develop and evaluate an automated formal synthesis approach that assists in decision-making for off-grid systems. Our proposed approach, called PVz, is based on a variant of the counterexample-guided inductive synthesis; it has a multi-core feature, which can obtain the optimal sizing of photovoltaic systems focusing on Life Cycle Cost analysis. Given the electrical needs of a home, we seek a set of electrical equipment with the best possible combination of devices that meet the specified requirements. We calculate all costs related to maintenance over 20 years. The results presented are based on seven case studies; some of them are real ones from the Amazon region in Brazil. The same case studies were solved by a commercial optimization tool. Our technique and the commercial tool results were validated with popular simulation software to perform a fair comparison. Furthermore, we analyze some topics such as run-time, optimal solution, and configuration of the resulting systems. We claim that our technique is advantageous compared to the existing approaches in the literature.p, li { white-space: pre-wrap; }
Metamaterial-Based Reconfigurable Intelligent Surface: 3-D Meta-Atoms Controlled by Graphene Structures
Authors: Molero Carlos , Palomares-Caballero Ángel , Alex-Amor Antonio , Parellada-Serrano Ignacio , Gamiz Francisco , Padilla Pablo , Valenzuela-Valdés Juan
Published: April 2021

The upcoming high-speed wireless communication systems will be hosted by millimeter and sub-millimeter-wave frequency bands. At these frequencies, electromagnetic waves suffer from severe propagation losses and non-line-of-sight (NLOS) scenarios. A new wireless communication paradigm has arrived to resolve this situation through the use of reconfigurable intelligent surfaces (RIS). These metadevices are designed to reconfigure the wireless environment in a smart way. Traditional RIS designs based on the implementation of 2-D configurations have been considered up to now. However, 3-D structures enable an extra degree of freedom in the design that can be taken as an advantage for the development of improved RIS structures with advanced functionalities. This article proposes the implementation of a novel electronically-reconfigurable RIS based on the use of 3-D graphene meta-atoms. The reconfigurability lies on the graphene conductivity, easily tunable with a biasing voltage. Different conductivity values vary the meta-atom electromagnetic response, modifying the RIS functionality. A multi-objective optimization framework determines the optimal phase state of each meta-atom to accomplish the desired RIS performance. The operation of the RIS as an efficient beam steerer/splitter, absorber and polarization selector is validated with full-wave results.

Published: April 2021

A noção de raça como um conceito relacional, atrelado à análise sociológica, e que se consolida e manifesta na contemporaneidade através de processos políticos e históricos é essencial para a melhor compreensão da sociabilidade humana moderna. Neste sentido, o trabalho aqui elaborado visa corroborar a hipótese de que o processo de modernização do Brasil é, para além de conservador,  fundamentalmente racista. Para alcançar tal objetivo o presente artigo analisa, através de uma leitura histórica de desenvolvimento econômico, as principais características que marcaram o período de transição organizacional do país em direção à ordem moderna. O estudo tem como marco cronológico inicial o ano de 1850, e possui ênfase nas políticas modernizantes elaboradas durante a Era Vargas (1930-1945). Se escancara ao longo do texto como o racismo que se observa hoje no Brasil é de fato a expressão de um processo concreto e profundo de exclusão material.
Estado, mídia e Capital
Authors: Bento da Silva Dayvison Wilson
Published: April 2021

O presente trabalho objetiva constituir uma abordagem institucional sobre o racismo ao analisar a relação entre repressão estatal direta e discurso ideológico de legitimação, baseando-se nos conceitos de ''Aparelhos Ideológicos de Estado'' e ''Aparelho Repressivo de Estado'', de Althusser. Para tanto, o termo “tropes” foi utilizado em um esforço de expor que, no capitalismo, violência estatal e exploração da população negra (ex.: encarceramento em massa e genocídio) buscam legitimar-se através da construção de narrativas fixas e pejorativas sobre os negros. Estas, por sua vez, circulam pelos meios de comunicação em massa e influenciam o imaginário social ao ocultar ou legitimar tal violência. Na primeira parte será abordada a relação entre racismo institucional e aparelhos ideológicos de Estado; na segunda, a conceituação de tropes e sua função ideológica; por fim, na terceira, uma análise sobre a aplicação dos tropes como aparelho ideológico ao longo dos séculos XX e XXI.

Interrelations between people and space-thing environment – erotism and buttle – in Petronius Arbiter’s “Satyricon”
Authors: Freivert Liudmila
Published: April 2021

This article is the investigation of interrelations between people and things in Petronius’s “Satyricon”. There is erotic component, “libido”, not only for people, but in interaction between people and things – furniture, utensil and other.
Petronius interests only mobile things and drama, events with their participation. Many things in Petronius’s text are dedicated to manipulations. People and things exist in cramped living space, when it happened traumas and breakages. Many details are elements characterizing biography and psychology of persons.
Numerous pages of the novel are devoted important themes of Ancient Rom culture: a body and its surface, truth and lie, appearance and essence. The thoughts by Russian thinker Vyacheslav Ivanov about mask and “drama of transfigurations” are truthful not for only Hellas, but for Ancient Rom and Petronius’s text too.
The novel is the authentic source about “space-things environment” in Ancient Rom of Nero’s epoch. It is full of postmodernist anticipations with erotism and irony.
Body of person feels different sensations. This material Eros is not accompaniment, but it is the major, important part of this text and its structure.
So, Rom literature is more earthbound. Mythological frame is manifested less clearly, then in Hellas, but Dionysian is its important component, and Petronius is the shining example. This unique situation in Ancient epoch shall not be repeated later.

Introduction

Patient safety is a central principle of healthcare professional practice that requires a significant consideration within the teaching curricula; however, there is a lack of special courses that focus on patient safety concepts in an integrated way in many countries. This study aims to assess the knowledge of medical and pharmacy students regarding patient safety concepts.

Methods

A cross-sectional study was conducted at Alfaisal University during the 2018-2019 school year. A survey consisting of 15 questions was designed with the help of the quality and patient safety department at King Faisal Specialist Hospital and Research Centre, Riyadh (KFSHRC). The survey was validated and then electronically distributed to all students enrolled in the College of Medicine and College of Pharmacy.

Results

A total of 304 (22%) of 1368 students completed the survey. The survey revealed that 51% of students had an acceptable understanding of the types of human error; however, 53% of students had little knowledge about the factors that lead to these errors and 61% did not know how to report an error. Many students (41%) reported being directly involved in an unsafe situation that may cause patient harm, such as a healthcare-related error, adverse event, or inconsistent care. Most students (90%) agreed that hiding errors to avoid further implications is unethical and reporting errors is the responsibility of every healthcare provider.

Conclusion

Most Alfaisal University students understand the significance of patient safety education and understand the types of human errors, yet the causes of errors and the protocols for reporting them were not well understood by most students.
