Juan Rulfo : Su vida, su tiempo y su obra

Sergio Lopez Mena 서울대학교 스페인중남미연구소 2005 이베로아메리카硏究 Vol.16 No.-

En la narrativa mexicana del siglo XX, en la que destacan Mariano Azuela, Martín Luis Guzmán, José Revueltas, Agustín Yáñez, Juan José Arreola y Juan Rulfo, este último sobresale por la autenticidad de su lenguaje y el carácter renovador de sus propuestas literarias. La vida de Rulfo abarca una etapa crucial de la historia contemporánea de México, la de la institucionalización de la Revolución Mexicana, época en que florece culturalmente el nacionalismo. En sus cuentos, expresión de una mentalidad de los hombres del campo, Rulfo construyó con intensidad seres en situación límite, con la violencia como signo más evidente. En su novela Pedro Páramo, está la idiosincrasia de un amplio grupo social, pero además la profundización en los misterios del hombre universal, particularmente en la veta de la pasión amorosa. Novela dialógica, desprovista del tradicional punto de vista moralizante, es Pedro Páramo una obra auténtica, de fina poesía. Por otra parte, la obra fotográfica de Rulfo, que lo muestra como un experto en ese arte, da testimonio del México de todos los tiempos, con la pobreza de su gente, la aridez de sus campos, la ternura de sus indígenas.

Laparoscopic Liver Resection of Segments 7 and 8: from the Initial Restrictions to the Current Indications

Victor Lopez-Lopez,Yusuke Ome,Yusuke Kawamoto,Alvaro Gómez Ruiz,Ricardo Robles Campos,Goro Honda 대한내시경복강경외과학회 2020 Journal of Minimally Invasive Surgery Vol.23 No.1

Since the beginning of laparoscopic liver surgery, resection of the posterosuperior segments has been considered one of the most challenging procedure due to its difficult access. The main drawbacks of the laparoscopic approach to dome lesions are poor visualization, the difficulty of instrumentation and the greater complexity in the control of bleeding. In the evolution of minimally invasive techniques from hybrid techniques to the current purely laparoscopic approaches, the different authors have established gradually the currents indications and surgical techniques to operate these segments with a similar feasibility and safety than open approach. The standardization in the patient position, the use of intercostal trocars, the learning curve in laparoscopic liver surgery, the management of the hepatic blood flow and the refinement of the technique in the extrahepatic and intrahepatic Glissonean pedicle approaches, has allowed to leave behind the initial contraindications about the laparoscopic approach in these segments. In the present review of the literature, the accumulated experience of the different groups in minimally invasive liver surgery together with the technological advances in the different laparoscopic devices have facilitated the resection of tumors in segments 7 and 8 with similar and even better results than open surgery.

Application of Frictional Bond-Slip Model to Large-Scale FRP-Strengthened T-Beams with U-wraps

Jaeha Lee,Maria Lopez 한국콘크리트학회 2020 International Journal of Concrete Structures and M Vol.14 No.1

Studies on U-wraps generally focus on the experimental results and mechanisms of the shear strengthening effect. Only a few studies have focused on the anchoring effect of the longitudinal FRP due to addition of the U-wrap. Lee and Lopez (Constr Build Mater 194:226–237, 2016) have found experimentally from pull-out tests that incremental changes occur in the debonding strain at the concrete-FRP interface depending on the various type of U-wraps. The proposed numerical method using the Frictional Bond-Slip (FBS) model has been validated by comparing the pull-out test results (Lee and Lopez Constr Build Mater 194:226–237, 2016). In the present study, the FBS model was applied to characterize the behavior of a large scale FRP strengthened T-beam with multiple U-wraps. First, the 2-dimensional (2D) model for pull-out test was developed. Debonding load and behavior of the model were compared with both the experimental results (Lee and Lopez Constr Build Mater 194:226–237, 2016) and the simulation results of a 3-dimensional (3D) model from a previous study (Lee and Lopez Constr Build Mater 194:226-237, 2016). Next, the 2D model was applied to model the behavior of a large scale FRP strengthened T-beam with multiple U-wraps. The conducted 2D simulation using the proposed FBS model predicted well the strains at various locations on the FRP sheet, the flexural capacity and complex failure mode of the FRP strengthened beam with several U-wraps. The proposed FBS model was also applied to other comparable studies, and debonding strains were successfully predicted within an margin of error of 7%. Using the validated model, a parametric study of the FRP strengthened T-beam was conducted with various key parameters of the U-wrap, such as the angle of U-wrap and the number of U-wrap.

Effect of the Combination Hot Water - Calcium Chloride on the In Vitro Growth of Colletotrichum gloeosporioides and the Postharvest Quality of Infected Papaya

Ayon-Reyna, Lidia Elena,Lopez-Valenzuela, Jose Angel,Delgado-Vargas, Francisco,Lopez-Lopez, Martha Edith,Molina-Corral, Francisco Javier,Carrillo-Lopez, Armando,Vega-Garcia, Misael Odin The Korean Society of Plant Pathology 2017 Plant Pathology Journal Vol.33 No.6

Anthracnose of papaya fruit caused by the fungus Colletotrichum gloeosporioides is one of the most economically important postharvest diseases. Hot water immersion (HW) and calcium chloride (Ca) treatments have been used to control papaya postharvest diseases; however, the effect of the combination HW-Ca on the pathogen growth and the development of the disease in infected papaya fruit has been scarcely studied. The aim of this study was to evaluate the effect of the HW-Ca treatment on the in vitro growth of C. gloesporioides conidia and the quality of infected papaya. In vitro, the HW-Ca treated conidia showed reduced mycelial growth and germination. In vivo, the HW-Ca treatment of infected papaya delayed for 5 days the onset of the anthracnose symptoms and improved the papaya postharvest quality. The combined treatment HW-Ca was better than any of the individual treatments to inhibit the in vitro development of C. gloeosporioides and to reduce the negative effects of papaya anthracnose.

Hallyu y su impacto en la sociedad mexicana

LOPEZ ROCHA NAYELLI 한국스페인어문학회 2012 스페인어문학 Vol.0 No.64

Durante las dos décadas pasadas, la República de Corea ha dado pasos agigantados en el desarrollo de sus sectores económico y político. Aunque ambos sectores son los que impactan de manera más evidente a nivel internacional, el aspecto sociocultural, el cual generalmente es menos documentado, ha tenido un impacto más sustancial en la proyección y diseminación de la cultura coreana más allá de sus fronteras. La República de Corea ha desarrollado diferentes maneras de interactuar en el plano internacional, por ello, desde finales de la década de los noventas, se percató de la ventaja de integrar el aspecto socio-cultural para el crecimiento continuo y progresivo del país, entendiendo que la sociedad y la cultura son la base para el desarrollo de éste. Sin la comprensión profunda de estos dos elementos, los sectores económico y político en sí mismos perderían fuerza. Por ello, en este estudio se investiga un fenómeno cultural coreano que ha impactado en otras sociedades del mundo de manera sorprendente. Su dispersión ha alcanzado sociedades no sólo lejanas en el aspecto regional, sino también en el aspecto cultural. Así, debido a la importacia de este fenómeno socio- cultural, en este trabajo se analiza el “Hallyu” u “Ola Coreana” y su impacto en la sociedad mexicana, permitiendo observar de una forma práctica el impacto del Hallyu en sociedades extranjeras tomando como estudio de caso a la sociedad mexicana.

Analysis of Workplace Accidents in Automotive Repair Workshops in Spain

Lopez-Arquillos, Antonio,Rubio-Romero, Juan Carlos Occupational Safety and Health Research Institute 2016 Safety and health at work Vol.7 No.3

Background: To analyze the effects of the factors associated with different types of injury (superficial wounds, dislocations and sprains, bone fractures, concussion and internal injuries, burns scalding and freezing) caused by occupational accidents in automotive repair workshops. Methods: Study of a sample consisting of 89,954 industry accidents reported from 2003 to 2008. Odds ratios were calculated with a 95% confidence interval. Results: Belonging to a small company is a risk factor for suffering three of the five types of injury studied. Women are less likely to suffer burns and superficial wounds, and more likely to suffer dislocations or sprains. Foreign workers are more likely to suffer concussion and internal injuries. Conclusion: Health and safety strategies and accident prevention measures should be individualized and adapted to the type of worker most likely to be injured in each type of accident. Occupational health and safety training courses designed according to worker profile, and improving the participation of the workers in small firms creating regional or roving safety representatives would improve working conditions.

The Software Architecture of A Secure and Efficient Group Key Agreement Protocol

Lopez-Benitez, Noe Convergence Society for SMB 2014 융합정보논문지 Vol.4 No.3

Group communications are becoming popular in Internet applications such as video conferences, on-line chatting programs, games, and gambling. Secure and efficient group communication is needed for message integration, confidentiality, and system usability. However, the conventional group key agreement protocols are too much focused on minimizing the computational overhead by concentrating on generating the common group key efficiently for secure communication. As a result, the common group key is generated efficiently but a failure in authentication allows adversaries to obtain valuable information during the group communication. After achieving the secure group communication, the secure group communication should generate the group key efficiently and distribute it to group members securely, so the balance of security and system usage must be considered at the same time. Therefore, this research proposes the software architecture model of a secure and efficient group communication that will be imbedded into networking applications.
