Vicente Navarro,Laura Asensio,Heidar Gharbieh,Gema De la Morena,Veli-Matti Pulkkanen 한국원자력학회 2019 Nuclear Engineering and Technology Vol.51 No.4

This work describes the development of a numerical module with a multiphysics structure to simulatethe thermo-hydro-chemo-mechanical behavior of compacted bentonites. First, the conceptual model,based on the state-of-the-art formulation for clay-based engineered barriers in deep geological repositories,is described. Second, the advantages of multiphysics-based modules are highlighted. Then, theguidelines to develop a code using such tools are outlined, presenting an example of implementation. Finally, the simulation of three tests that illustrate the behavior of compacted bentonites assesses thescope of the developed code. The satisfactory results obtained, and the relative simplicity of implementation,show the opportunity of the modeling strategy proposed

( Vicente Ortiz ),( Diego Alvarez-sotomayor ),( Esteban Saez-gonzalez ),( Francia Carolina Diaz-jaime ),( Marisa Iborra ),( Julio Ponce ),( Vicente Garrigues ) 대한간학회 2017 Gut and Liver Vol.11 No.3

Background/Aims: To evaluate esophageal sensitivity to acid between morbidly obese (MO) patients and non-MO controls with abnormal esophageal acid exposure. Methods: We conducted a cross-sectional study of 58 patients: 30 MO (cases) and 28 non-MO (controls). Esophageal symptoms and esophageal sensitivity to 0.1 M hydrochloric acid solution (Bernstein test) were compared between MO and non- MO patients with a prior diagnosis of abnormal esophageal acid exposure. Results: MO patients were less symptomatic than non-MO controls (14% vs 96%; odds ratio [OR], 0.006; 95% confidence interval [CI], 0.001 to 0.075; p=0.000). MO patients were more likely to present with decreased esophageal sensitivity to the instillation of acid than non-MO controls (57% vs 14%; OR, 8; 95% CI, 1.79 to 35.74; p=0.009). Subgroup analysis revealed no differences in esophageal sensitivity in MO patients with and without abnormal esophageal acid exposure (43% vs 31%; p=0.707). Conclusions: Silent gastroesophageal reflux disease (GERD) is common among MO individuals, likely due to decreased esophageal sensitivity to acid. The absence of typical GERD symptoms in these patients may delay discovery of precancerous conditions, such as Barrett`s esophagus. We believe that these patients may require a more aggressive diagnostic work-up to rule out the presence of silent GERD. (Gut Liver 2017;11:358-362)

Potential strategies for prevention of tumor spillage in minimally invasive radical hysterectomy

Vicente Bebia,Sonia Monreal-Clua,Assumpció Pérez-Benavente,Silvia Franco-Camps,Berta Díaz-Feijoo,Antonio Gil-Moreno 대한부인종양학회 2020 Journal of Gynecologic Oncology Vol.31 No.5

Objective: The publication of a prospective [1] and several retrospective [2,3] studiesdescribing a worse prognosis in patients affected with early-stage cervical cancer whounderwent a minimally invasive radical hysterectomy has raised a high concern in whatmeasures should be undertaken in order to revert these results. Potential strategies [4] toprevent tumor spillage have been previously proposed. Methods: In this video, we describe nine strategies that should be addressed in future trialsregarding this procedure. Results: These strategies are:1. Fallopian tubes should be coagulated prior to start the surgery. 2. All sentinel lymph nodes and lymphadenectomy specimens should be obtained withoutlymph nodes fragmentation. 3. All surgical specimens should be extracted within a containment bag. 4. Uterine manipulators must never be used. 5. Prior to vaginal section, a closed knotted ligature should be placed around the vagina,proximal to the section line, and the remaining vaginal cavity profusely washed. 6. Once the vagina is opened, the surgical specimen should be extracted vaginally within aspecimen retrieval bag. 7. After surgery, the pelvic cavity is profusely washed with physiological serum, and the vaginashould be washed with iodopovidone diluted to 10% [5]. 8. Port-site metastasis prevention measures should be performed. 9. Every action made to prevent tumor spillage should be recorded in the surgical report. Conclusion: As there is a biological rationale in these measures that would prevent tumorspillage and seeding, there is a need of prospectively exploring them within appropriatestudies in order to determine their own oncological outcome.

Simple Fractional Order Controller Combined with a Smith Predictor for Temperature Control in a Steel Slab Reheating Furnace

Vicente Feliu-Batlle,Raul Rivas-Perez,Fernando J. Castillo-García 제어·로봇·시스템학회 2013 International Journal of Control, Automation, and Vol.11 No.3

This paper proposes a simple fractional order controller combined with a Smith predictor scheme for controlling the temperature of a steel slab reheating furnace. The dynamic model of the preheating zone of this process is obtained from an identification procedure applied in an industrial furnace. This identification procedure yields a second order plus time delay transfer function which undergoes large time delay changes. A fractional order integral controller combined with a Smith predictor is therefore designed. Simulated results compare the performances of the proposed fractional order controller with a standard PI controller, also combined with a Smith predictor, an LQR controller, and an H∞ robust controller, in the case of the nominal process, and when the time delay varies. Four performance indexes have been used in this comparison: three related to the output performance (settling time, overshooting, and integral absolute error (IAE)), and a fourth one related to the control effort (TV). The analysis of these indexes shows that the simple fractional order controller provides lower values of the compared indexes when time delay becomes much higher than the nominal value.

Early Access to COVID-19 Vaccines and Rodrigo Duterte-style Vaccine Diplomacy

Vicente Angel S. Ybiernas 부산외국어대학교 아세안연구원 2022 Suvannabhumi Vol.14 No.2

Vaccine nationalism and its implications to vaccine supply were a huge concern globally when COVID-19 vaccines first became available in 2021. At the time, vaccine supply was limited and it was difficult for many countries around the world to get adequate supply of the COVID-19 vaccine to inoculate their people. At its most benign, vaccine nationalism delayed the access of poorer countries to vaccines that are widely considered as the long-term solution to the COVID-19 pandemic. Poorer countries needed to resort to diplomacy to wrangle early access to vaccine supply from vaccine-producing countries like the United States, the United Kingdom and others. In particular, Philippine President Rodrigo Duterte leveraged his country’s Visiting Forces Agreement (VFA) with the United States and the need for Filipino nurses by countries like the United Kingdom and Germany to secure early access to COVID-19 vaccines. It all seems trivial now (in 2022) because of better global vaccine supply, but in 2021 when countries scrambled for access to scarce COVID-19 vaccines, Rodrigo Duterte leveraged the Philippines’ assets to gain early access to vaccine supply.

Purpose: This study was performed to evaluate the long-term evolution of continence and patient’s quality of life after surgical treatment for obstetric fecal incontinence. Methods: A prospective longitudinal study was conducted including consecutive patients who underwent sphincteroplasty for severe obstetric fecal incontinence. The first phase analyzed changes in continence and impact on quality of life. The second phase studied the long-term evolution reevaluating the same group of patients 6 years later. Degree of fecal incontinence was calculated using the Cleveland Clinic Score (CCS). Quality of life assessment was carried out with the Fecal Incontinence Quality of Life scale. Results: Thirty-five patients with median age of 55 years (range, 28 to 73 years) completed the study. Phase 1 results: after a postoperative follow-up of 30 months (4 to 132 months), CCS had improved significantly from a preoperative of 15.7±3.1 to 6.1±5.0 (P<0.001). Phase 2 results: median follow-up in phase 2 was 110 months (76 to 204 months). The CCS lowered to 8.4±4.9 (P=0.04). There were no significant differences between phases 1 and 2 in terms of quality of life; lifestyle (3.47± 0.75 vs. 3.16±1.04), coping/behavior (3.13±0.83 vs. 2.80±1.09), depression/self-perception (3.65±0.80 vs. 3.32± 0.98), and embarrassment (3.32±0.90 vs. 3.12±1.00). Conclusion: Sphincteroplasty offers good short-medium term outcomes in continence and quality of life for obstetric fecal incontinence treatment. Functional clinical results deteriorate over time but did not impact on patients’ quality of life.

There isn’t doubt that our planet faces daily environmental damages, this is consequence of human action on nature and its resources. This has been observed since the man appears in the world, and will continue to happen, unfortunately more and more quickly. For over 40 years have sought solutions to environmental problems, one being the establishment of economic instruments and creation of environmental taxes to achieve the aims and objectives of public policy is clear and necessary public intervention in environmental matters. This paper seeks to highlight and explain the feasibility of establishing environmental taxes and the need for the adequacy and strict application of environmental policies and the continuing joint work of the States and the Federation to achieve satisfactory results with the implementation of these environmental instruments that complement our tax system. Key Words: Economic Instruments; Environmental Taxes; Public Politics; Environment; Sustainable Development Resulta indudable que nuestro planeta a diario enfrenta el deterioro del medio ambiente, ello como consecuencia de la acción humana sobre la naturaleza y sus recursos. Esto se ha presentado desde el inicio de la humanidad y desafortunadamente seguirá sucediendo cada vez con mayor rapidez y frecuencia. Desde hace más de 40 años se han buscado soluciones a la problemática ambiental, siendo el establecimiento de instrumentos económicos y la creación de tributos ambientales un medio para lograr los objetivos y fines de las políticas públicas sobre la materia, resultando evidente y necesaria la intervención pública en materia ambiental. Este trabajo pretende dar a conocer y explicar el estado del arte, la viabilidad del establecimiento de impuestos ambientales, así como la necesidad de la adecuación e implementación estricta de las políticas medio ambientales, siendo indispensable para ello el trabajo conjunto y continuo de la Federación y de los Estados para lograr resultados satisfactorios con la implementación de estos instrumentos ambientales convirtiéndose en un complemento de nuestro sistema tributario.
