Adrenaline damage to the myocardium is an important element in the pathogenesis of myocardial infarction in humans. Despite the use of modern methods of treatment of myocardial infarction, the issue of cardioprotection of reperfusion myocardial damage remains open. Promising in this direction is the use of quinazolone derivatives, which have already shown cardioprotective properties in other models of myocardial infarction. The aim of the study was to establish morphological changes in the conditions of adrenaline myocardiodystrophy (AMD) against the background of the introduction of the compound PC-66 and amiodarone in rats. The study was performed on 100 nonlinear rats of both sexes weighing 165-220 g, divided into four groups of 25 animals each: 1 – intact rats; 2 – rats with a model of adrenaline myocardial infarction without treatment (control); 3 – rats with AMD treated with amiodarone (10 mg/kg, intraperitoneally); 4 – rats with AMD treated with compound PC-66 (10 mg/kg, intraperitoneally). It was found that control rats under conditions of cardiotoxic dose of adrenaline in the left ventricular myocardium for up to 8 days of the experiment does not fully restore the myocardial structure, dystrophic and necrobiotic changes were found in both cardiomyocytes and walls of vessels of a blood microcirculatory channel of a myocardium. Course intraperitoneal administration to rats of the compound PC-66 in the conditions of adrenaline myocardial infarction as well as amiodarone, contributes to the attenuation of signs of dystrophic and destructive processes. The degree of protective effect on the myocardium under conditions of cardiotoxic dose of adrenaline compound PC-66 was not lower to the reference drug – amiodarone. Thus, it is morphologically confirmed that in adrenaline myocardial infarction the compound PC-66, similar to the action of amiodarone, has a cardioprotective effect.

Published: May 2020

Pilonidal disease is a pathology that was first described more than 100 years ago. However, it still remains the subject of discussion, because there is still no clear unambiguous definition of this pathology, nor its well-known etiology. Despite the large number of developed and substantiated theories, there are still two opposing views on the cause of pilonidal disease. Some scientists are supporters of the “congenital” theory, others – the theory of acquired origin. However, this does not clarify the ultimate goal of these studies: to develop optimal treatment tactics. The purpose of the work is to clarify the data on the etiology of pilonidal disease in children. The study is based on the results of treatment analysis of 37 children diagnosed with “pilonidal disease” who were hospitalized in the Department of Emergency Surgery of Vinnytsia Regional Children’s Clinical Hospital, of which boys – 26, girls – 11. The mean age of patients was 16.4±0.4 years. Histological sections of tissue samples were stained with hematoxylin and eosin. Microscopy and creation of a photo archive of histological specimens were performed using a light microscope OLIMPUS BX 41 at a magnification of 100 and 200, in the software environment “Quick PHOTO MICRO 2.3”. The study found that there are significant differences in the histological structure of pilonidal cysts in children and adults. In pediatric patients, mesenchymal tissue was found, which is not typical for this group of patients. It was also found that the cavity of the pilonidal cyst in children is covered with a multilayered squamous non-keratinizing epithelium, and there is almost no granulation tissue. In our opinion, pilonidal disease is a polyetiological disease, the main cause of which is the congenital features of the organism, which are realized due to socio-economic and environmental factors.

Published: May 2020

Background: Among breast cancer survivors age > 50 years, deaths due to cardiovascular disease account
for 35% of non-cancer related deaths. The increases in cardiovascular disease among breast cancer survivors
is due to the cardiotoxic effects of breast cancer treatment and to overlapping risk factors for breast cancer
and cardiovascular disease.
Methods: We conducted a study of a sample of 164 breast cancer patients in order to examine the frequency
of cardiovascular disease. The overall objective was to examine the frequency of high blood pressure,
myocardial infarction, cardiomyopathy, congestive heart failure, stroke, and venous
thrombosis/thromboembolism among women who have been diagnosed with stage I-IV breast cancer and
who had completed primary therapy for the disease. Data were collected by postal survey and abstraction
of electronic medical records.
Results: A high percentage of the women (62.8%) had a reported history of high blood pressure. Fifty
percent of the women had a reported history of high cholesterol. About 8.3% of the women were current
smokers and 36.0% were former smokers. About 23.8% of the women had a reported history of diabetes.
About 4.9% of the women had a reported history of congestive heart failure and 6.1% had a history of
stroke.
Discussion: Additional studies are needed of cardiovascular risk factors and adverse cardiovascular events
among breast cancer survivors. Of particular concern is whether patients with hypertension,
hypercholesterolemia, and diabetes are receiving appropriate therapy to reduce their cardiovascular risk and
prevent morbidity and mortality from adverse cardiovascular events.

Published: May 2020

Background: Little is known about the clinicopathological findings in elderly patients with undifferentiated
advanced gastric cancer. The aim of this study was to clarify the clinical impact of clinicopathological
characteristics of those cancers in elderly patients.
Method: A total of 42 patients aged 80 years or older with advanced gastric cancer who had undergone
curative gastrectomy between 1998 and 2015 were included in this study. All patients were classified into
two principal subgroups based on histology: undifferentiated group and differentiated group. The two
groups were examined and compared with respect to the pathological findings and clinical outcomes.
Results: Of the 47 patients, 23 (49%) patients were in the undifferentiated group and 24 (51%) were in the
differentiated group. The undifferentiated cancer was less frequently located in the upper third of the
stomach than the differentiated cancer (4% vs 42%, P < 0.01). The frequency of the cancer with depth of
T4a was higher in the undifferentiated group than in the differentiated group (48% vs. 17%, P < 0.05). The
median number of metastatic lymph nodes in the undifferentiated group was more than that in the
differentiated group (3 vs. 1, P < 0.05). In short- and long-term outcome after curative gastrectomy, there
were no differences between the two groups.
Conclusion: In elderly patients, undifferentiated advanced gastric cancer may have more malignant
potential than differentiated cancer. However, by curative gastrectomy, the elderly patients with
undifferentiated advanced gastric cancer can be obtained the equivalent clinical outcome to those with
differentiated cancer.

OBJECTIVE

While the anterior lumbar interbody fusion (ALIF) procedure may be amenable to ambulatory surgery, it has been hypothesized that limitations such as the risk of postoperative ileus and vascular complications have hindered transition of this procedure to the outpatient setting. Identification of independent risk factors predisposing patients to inpatient stays of ≥ 24 hours after ALIF may facilitate better postsurgical outcomes, target modifiable risk factors, and assist in the development of screening tools to transition appropriate patients to the ambulatory surgery center (ASC) setting for this procedure. The purpose of this study was to identify the most relevant risk factors that predispose patients to ≥ 24-hour admission following ALIF.

METHODS

A prospectively maintained surgical registry was reviewed for patients undergoing single ALIF between May 2006 and December 2019. Demographics, preoperative diagnosis, perioperative variables, and postoperative complications were evaluated according to their relative risk (RR) elevation for an inpatient stay of ≥ 24 hours. A Poisson regression model was used to evaluate predictors of inpatient stays of ≥ 24 hours. Risk factors for inpatient admission of ≥ 24 hours were identified with a stepwise backward regression model.

RESULTS

A total of 111 patients underwent single-level ALIF (50.9% female and 52.6% male, ≤ 50 years old). Eleven (9.5%) patients were discharged in < 24 hours and 116 remained admitted for ≥ 24 hours. The average inpatient stay was > 2 days (53.7 hours). The most common postoperative complications were fever (body temperature ≥ 100.4°F; n = 4, 3.5%) and blood transfusions (n = 4, 3.5%). Bivariate analysis revealed a preoperative diagnosis of retrolisthesis or lateral listhesis to elevate the RR for an inpatient stay of ≥ 24 hours (RR 1.11, p = 0.001, both diagnoses). Stepwise multivariate analysis demonstrated significant predictors for inpatient stays of ≥ 24 hours to be an operation on L4–5, coexisting degenerative disc disease (DDD) with foraminal stenosis, and herniated nucleus pulposus (RR 1.11, 95% CI 1.03–1.20, p = 0.009, all covariates).

CONCLUSIONS

This study provides data regarding the incidence of demographic and perioperative characteristics and postoperative complications as they pertain to patients undergoing single-level ALIF. This preliminary investigation identified the most relevant risk factors to be considered before appropriately transitioning ALIF procedures to the ASC. Further studies of preoperative characteristics are needed to elucidate ideal ASC ALIF patients.
Double Vision, Phosphenes and Afterimages
Authors: Sarıhan Işık
Published: May 2020

Pure representationalism or intentionalism for phenomenal experience is the theory that all introspectible qualitative aspects of a conscious experience can be analyzed as qualities that the experience non-conceptually represents the world to have. Some philosophers have argued that experiences such as afterimages, phosphenes and double vision are counterexamples to the representationalist theory, claiming that they are non- representational states or have non-representational aspects, and they are better explained in a qualia-theoretical framework. I argue that these states are fully representational states of a certain kind, which I call “automatically non-endorsed representations”, experiential states the veridicality of which we are almost never committed to, and which do not trigger explicit belief or disbelief in the mind of the subject. By investigating descriptive accounts of afterimages by two qualia theorists, I speculate that the mistaken claims of some anti-representationalists might be rooted in confusing two senses of the term “seeming”.

Why Research and Publish?
Authors: Remulla Agnes
Published: May 2020

We have different reasons for publishing research. I can imagine the resident begrudging that without it, training would have been for naught. Then there are those rare individuals with whom the prospect of interesting research gives an inordinate sense of excitement. Many a time we say, “I’ve seen a case just like that” or “we’ve been doing that for a very long time”. But if it is not written, who can say that it happened?

Why research and publish?

Knowledge for the love of knowing. Basic research often pursues questions that may have no clear application yet. But there is always promise it will make sense in the future. These little bits of information have, in many instances, come together into a bigger “aha” moment later on.

Answer a question --- understand how, what, when, why. Every single day, we ask something that there is no clear answer to. Be it in the course of seeing patients in the clinic, doing surgery or in moments of quiet introspection. Each candid query has potential to be a developed into a valid and rational research question.

Share knowledge. The Philippine clinical environment is unique. Patient profiles, conditions and treatments may vary from those reported elsewhere. That new case unseen or rarely reported in literature will be lost to memory without publication. Sharing it as published scientific literature ensures that the information will be preserved and may be of use to others in the future.

Intellectual and academic impetus. Residents take heart. Consultants in academic institutions also have this requirement. “Publish or perish” is taken seriously in the academe. This push from teaching institutions hopefully results in amplified output to sustain both the professor’s needs and the medical community at large.

There are certainly more reasons. Which one is yours?

Why in the PJO-HNS?

We absorb information from all over the world and incorporate it into the daily grind of medical practice. But conditions by which Philippine ORL-HNS thrives is rife with its own special set of questions, answers, creative solutions, insight and the occasional surprise revelation. We have as much to share to the ORL-HNS community as the world has shared with us. The PJO-HNS, under the stewardship of Dr. Jose Florencio Lapeña, has achieved much in terms of ensuring that the researches it publishes gains international recognition with enhanced online accessibility. Thus, what is published in PJO-HNS will be searchable online and is linked within a system that allows ease of searching, citation and linking. Once it is written, published and uploaded, the information shared will never be lost or relegated to mere anecdotes.

There is much work to be done to further Philippine ORL-HNS research. As leaders of our specialty, the PSO-HNS enjoins all Fellows to foster that inquisitive spirit, search for answers and share this knowledge through the PJO-HNS. May this volume inspire you to contribute to this effort.

PENERAPAN BASEL ACCORD MELALUI PERHITUNGAN EKONOFISIKA DALAM MANAJEMEN RISIKO PERBANKAN
Authors: Khanifa Nurma Khusna
Published: May 2020

Dalam membantu menangani stabilitas reformasi sektor keuangan global di tengah kondisi ekonomi sedang mengalami perlambatan seperti sekarang ini di Indonesia perlu adanya gaya baru dalam mengelola risiko. Sampai saat ini perbankan dalam mengatasi risiko menggunakan basel accord bermula dari basel I, II, III. Di awal 2019 ini semua perbankan harus sukses menjalankan basel III. Akselerasi semacam itu telah menyebabkan bank-bank meningkatkan metodologi dan prosedur yang digunakan untuk mengukur dan mengelola risikonya. Betapapun hebatnya pengawasan yang digariskan Basel, haruslah disadari bahwa itu merupakan produk dari hegemoni paham neo-liberal, yang tentu tak selalu cocok untuk diterapkan di setiap negara, termasuk di Indonesia. Terilhami dari hal itu maka berimbas kepada sektor perbankan untuk menerapkan manajemen risiko. Dari sini muncul konsep baru melalui kolaborasi keilmuan antara ekonomi dan fisika. Kebutuhan akan fisikawan dalam bidang ekonomi dan keuangan ini sudah menjadi sesuatu yang tidak terelakan. Demi terciptanya bank yang sehat ekonofisika bersandar pada fakta empirik pada analisis risiko. Hal ini menunjukkan senantiasa berkembangnya ilmu manajemen risiko pada sistem perbankan di tanah air.
Educar para a liberdade em Kant: Reflexões acerca do projeto pedagógico na modernidade
Authors: Santos Willian Lima
Published: May 2020

O presente ensaio foi desenvolvido na disciplina de Fundamentos da Educação I, no curso de Mestrado Acadêmico em Educação da Universidade Federal de Sergipe (UFS), tendo como principal objetivo refletir sobre o modelo pedagógico kantiano na modernidade, traçando um elo entre disciplina, instrução e formação para a liberdade. Trata-se de um estudo bibliográfico, construído a partir do seguinte quadro teórico: Kant (1996), Menezes (1992), Menezes (2005), Menezes e Boto (2014). Diante das análises do material bibliográfico foi possível perceber que o ato de educar com disciplina em Kant é tirar o homem de seu estado bruto, eliminando a barbárie de sua essência, para que a sua animalidade não prejudique a formação do caráter, e consequentemente a sociedade.
Carbapenem Resistant Enterobacteriaceae in Africa
Authors: Gulumbe Bashar Haruna , Ajibola Olumide
Published: May 2020

Carbapenems are regarded as unique among the �-lactam antibiotics due to their broad spectrum of activity and ability to resist �-lactamase hydrolysis. Carbapenems are the only �-lactam antibiotics with efficacy in severe infections caused by extended-spectrum beta-lactamase (ESBL) producing bacteria. However, recent reports of carbapenem resistance particularly among members of Enterobacteriaceae that are responsible for diseases such as gastrointestinal infections, septicemia, pneumonia, meningitis, peritonitis as well as urinary tract infections, call for concerns. In Africa, the problem of carbapenem-resistant Enterobacteriaceae (CRE) is aggravated by factors such as the high rate of infections, poor diagnostic tools, sub-optimal disease surveillance, and abuse of antibiotics. Besides, the problem of CRE in Africa is understudied. This review distills available literature on the spread of CRE in Africa, CRE genes in circulation, and the need to pay attention to this emerging threat to lives in developing countries.

Numerical Analysis of Compressed Masonry Columns
Authors: Libecajtová Aneta
Published: May 2020

This paper presents a three-demensional micro-model for an unreinforced masonry (URM) column and masonry columns reinforced by FRP wrapping (RM). The column with dimensions of 0.3 x 0.3 x 1 m was constituted by twelve rows of solid burnt bricks bonded by mortar joints. The RM column was wrapped in four external FRP sheets. A heterogeneous model, in which masonry units, mortar joints and reinforcement are materially and geometrically accurately described, was chosen. Both bricks and mortar are modelled with independent behavior in compression and tension. The FRP reinforcement is assumed to behave linear-elastically. The reinforcement was modelled under the assumption of perfect adhesion between the elastic FRP strips and the damageable masonry support. Numerical results are compared with experimental ones in order to confirm conclusions about the behavior of URM and RM columns under concentric compressive load determined based on the experimental part of the research program. The comparison between experimental and numerical findings shows good agreement and the adopted numerical model is suitable to predict the ultimate load and allows a better understanding of the behavior of brick masonry columns under concentric compression before and after reaching the ultimate load. For all simulations, the commercial software package ABAQUS was used.
Characterization and Liquefaction Hazard Assessment of Two Hungarian Liquefied Sites from the 1956 Dunaharaszti Earthquake
Authors: Bán Zoltán , Győri Erzsébet , Tóth László , Gráczer Zoltán , Mahler András
Published: May 2020

The seismicity of Hungary can be considered moderately active, nevertheless contemporary reports from the past approx. 350 years documented surface manifestations of liquefaction occurrences. The last such earthquake was the 1956 Dunaharaszti ground motion, for which the location of two liquefied sites could be identified approx. 60 years after the event. This provided an excellent opportunity to analyze possibly the only accessible liquefied sites in Hungary. Analysis of the two sites included field and laboratory tests allowing the back-calculation of maximum horizontal ground acceleration of the earthquake. This parameter was previously unknown because the closest seismometer saturated during the event. The performed back-analysis using the principles of paleoliquefaction studies was the first of such analyses in the country. In areas with low to moderate seismicity, geotechnical engineers often neglect and overlook liquefaction hazard, however, when it is addressed, the hazard is often overestimated due to improper characterization of the seismic loading and site characterization. To explore this observation more deeply, probabilistic seismic and liquefaction hazard assessment were carried out at the two liquefied sites and it was found that this conclusion is also valid for Hungary, but the degree of conservatism of the pseudo-probabilistic procedures decreases with increasing earthquake return period (lower annual probability of occurrence).

Improving the productivity-susceptibility analysis to assess data-limited fisheries
Authors: Baillargeon GA , Tlusty MF , Dougherty ET , Rhyne AL
Published: May 2020

Each year, millions of marine aquarium fish and invertebrates are harvested from coral reefs and enter the complex and largely unregulated marine aquarium trade (MAT). It is challenging to identify species at risk of overexploitation in this trade due to its data-limited and poorly monitored nature. We developed a new analytical approach based on a productivity-susceptibility analysis (PSA) to assess the vulnerability of wild-captured marine aquarium fish. The PSA was originally developed to assess food fisheries; however, species and operational characteristics between food fisheries and the MAT differ. Thus, we improved a prior PSA framework to assess the data-limited MAT through customization of productivity and susceptibility factors to align with the target fishery, improved data binning, calculation of susceptibility, and characterization of the vulnerability scores. Our vulnerability results align well with the most recent IUCN assessments, showing improved accuracy using this revised PSA compared to prior adaptions of the PSA to the MAT. Further, we show that this PSA approach can be used to assess species on either a global or country-specific scale. A Gaussian mixture model clustering algorithm was applied to the PSA results to objectively classify fish along a sustainability continuum. Among 32 species, a majority of species clustered as highly sustainable or sustainable indicating little management or over-harvest concern; however, the Bangaii cardinalfish Pterapogon kauderni and blue tang Paracanthurus hepatus indexed as unsustainable. This novel PSA method, and use of a clustering algorithm to classify results, provides a predictive tool for a wide range of fisheries. In addition to informing species management plans, the compilation of sustainability status data generated by our PSA can inform a consumer guide, allowing consumers and other stakeholders to make sustainable decisions when purchasing fish.
VÁLLALATI HITELÁLLOMÁNY ELEMZÉSE AZ OTP BANK NYRT-NÉL
Authors: BELOVECZ Mária , IPACSNÉ GEDEI Beáta , HALMOSI Tímea
Published: May 2020

Magyarországon 2017-ben lett 30 éves a kétszintű bankrendszer. Mára, több mint 10 évvel a válság kirobbanása után a banki és vállalati szektor is kezd ismételten magára találni, így érdemes a köztük lévő kapcsolatokban bekövetkező változásokat megvizsgálni.

A vizsgálatainkat negyedéves adatok alapján végezzük 2011-től, hogy a 2008-as világválság utáni, esetlegesen adattorzító adatoktól mentesítsük elemzésünket. A 2011-2016-os időszakra vetítve lineáris korrelációs együttható vizsgálattal elemezzük, hogy a különböző gazdasági beavatkozások, hogyan hatnak az OTP Bank vállalati hitelezési állományára.

A lineáris korrelációs együttható elemzésénél a mikro– és kisvállalkozói ügyfélkört és a közép- és nagyvállalati ügyfélkört külön elemezzük. A mikro- és kisvállalkozói ügyfélkör a vizsgálat minden egyes területén erősebben korrelál a gazdasági eseményekre az adott T időszakban, mint a közép-és nagyvállalati ügyfélkör.

A hitelállomány-változásának elemzését a hitelezési feltételek változásának és a hitelkamatok változásának vizsgálatára is elvégezzük. A módszer alkalmazása révén kapott eredmény alapján, a mikro-és kisvállalati ügyfélkör a vizsgálat elemeivel T időszakra erősebb korrelációt mutat a közép-és nagyvállalati ügyfélkörnél. Az elemzés azt is megerősíti, hogy T időszakra vetítve a hitelkamatokkal a vállalatok jóval erősebben korrelálnak, mint a hitelezési feltételekkel, ami alátámasztja azt, hogy a kamatokra nagyon érzékeny a vállalati ügyfélkör. Ez a tény indokolttá teszi a hiteltermékek megújítását, az egyedi kondíciós kamatkedvezményeket, mely az új és meglévő ügyfelek hitelkihelyezései révén a jelenlegi betéti állomány pufferét is csökkentené, jobb és növekvő eredményeket biztosítva.

Translation and Validation of Religious Attitude Scale: Role of Demographic Variables
Authors: Ayub Hamna , Kiran Nelofar` , Khan Saira
Published: May 2020

The study aimed to translate the Religious Attitude Scale (RAS; Onay, 2000) into Urdu language and established its construct validity in Pakistani culture. Moreover, the relationship of different demographic variables (i.e., age, income, gender, family system) with religious attitude of parents was also explored. The study comprised of two phases: Phase I of the study constituted translation of the original English version of RAS into Urdu language using forward and back translation method. In phase II, the construct validity of RAS was established through Exploratory Factor Analysis and psychometric properties of RAS were determined. A sample (N = 264) of parents comprising mothers (n = 133) and fathers (n = 131) with age range of 26 to 52 years (M = 34.74, SD = 6.0) participated in the study. Results showed that RAS has two factors namely Positive Religious Attitudes and Negative Religious Attitudes. Psychometric properties of the scale were satisfactory. Findings showed that religious attitudes had positive relationship with age; while, were negatively associated with income. Findings revealed nonsignificant differences across gender of the parents on religious attitudes; whereas, individuals belonging to nuclear families had significantly lower religious attitudes than those from joint family system. Future implications were also discussed.
Association Between Severity of Adolescents’ Peer Problems and Moral Judgment Development
Authors: Zulfiqar Najia
Published: May 2020

Previous studies supported that adolescents’ moral judgment decreases as their peer problems increase in severity. The objective of the present research was to examine peer problems as a predictor of adolescents’ moral judgment development based upon Jessor’s problem behavior theory and Gibbs moral development theory. It was hypothesized that moral judgment increases with growing age and thus, older adolescents are expected to be at higher stages of moral judgment development than younger adolescents. It was also assumed that adolescents with severe peer problems will be at lower level of moral judgment development than their counterparts. The younger adolescents (n = 140; M = 13.1 year) and older adolescents (n = 147; M = 19 year) were compared on measures of Index of Peer Relations and Padua Moral Judgment Scale. The findings showed that adolescents’ moral judgment development declined with an increase in peer problems, particularly during late adolescence. Adolescents who reported having moderate and severe peer problems had lower level of moral judgment development than those with no and mild peer problems. Findings provided guideline for future researchers and practitioners.

The present study was carried out to investigate the experiences of sexual harassment among female prisoners in jail. 100 female prisoners from central jails of Gujrat and Gujranwala district (Gujrat = 35, Gujranwala = 65) participated in the study. The data were collected by using purposive sampling. Sexual Harassment Experiences Questionnaire (Kamal & Tariq, 1997) was used to measure study variable. Data were analyzed using descriptive and inferential statistics. Mean, standard deviation
(M = 151.2, SD = 12.28) and graphical representation of data were made in descriptive statistics. In inferential statistics, Shapiro-Wilk's test was used which indicated normal distribution of data (p = .76). Further, two-step cluster analysis was applied to identify level of sexual harassment among female prisoners. Results of cluster analysis categorized data into three levels high, medium and low. The study established that 80% of respondents scored on medium level of Unwanted Sexual Attention and 9% of respondents scored on high level of Gender Harassment, whereas, 11% of respondents scored on low level of Sexual Coercion. Overall, results of study depicted that there was medium level of sexual harassment among female prisoners. Results of this study would be useful for policy makers and higher administration of the Jail department in order to improve jail environment by preventing sexual harassment.

El objetivo, es relacionar las reformas institucionales con los indicadores económicos alcanzados en materia de competitividad, tomando como referencia la evolución en la posición competitiva alcanzada en el índice de competitividad global. Se ha utilizado una metodología de investigación descriptiva y aplicada con enfoque mixto, que parte desde la teoría para llegar a causalidades y conclusiones sobre el fenómeno de estudio. El trabajo introduce un modelo teórico denominado, esquema de política económica estructural, el cual se orienta al fomento del desarrollo productivo a través de las políticas económicas estructurales, como base (causa) que genera los incrementos del ingreso y del gasto (efectos) en la economía. Los resultados demuestran que los cambios institucionales incidieron en el mejoramiento competitivo de 31 puestos en la posición del Ecuador periodo 2013-2014 respecto al periodo 2007-2008. Desde el periodo 2015-2016 y hasta el periodo 2017-2018 se puede evidenciar un retroceso significativo de 26 posiciones, lo cual expone la vulnerabilidad y dependencia de la estructura productiva ecuatoriana.

El presente trabajo tiene por objetivo analizar el nivel de influencia de las redes sociales ante el éxito empresarial, ha sido desarrollado a través de dos herramientas de investigación, la primera consiste en un cuadro de observación hacia las redes sociales gestionadas por las empresas seleccionadas como objeto de estudio, cuyo análisis se realizó en base a cuatro ítems: actividad, comunidad, visibilidad e interactividad; en cuanto a la segunda herramienta, se destaca el uso de una encuesta de escala Likert, que ha permitido conocer la percepción de los consumidores referente al uso de redes sociales como herramienta de información para sus tendencias de compra. Los instrumentos aplicados, permitieron determinar que la gestión en redes sociales no representa un punto clave frente al éxito empresarial, no obstante, de las 5 empresas analizadas, menos del 50% gestiona redes sociales, permitiendo rechazar la hipótesis planteada, es decir, que la gestión de redes sociales en una empresa no influye de manera significativa en las utilidades, existe una baja frecuencia de publicaciones tanto en las empresas con mayores utilidades, como en las empresas de utilidades negativas consideradas en el estudio, sin embargo, el nivel de utilidades considerado para ambos listados, posee una diferencia significativa.
Numerical and Experimental Investigation of the Design of a Piezoelectric De-Icing System for Small Rotorcraft Part 1/3: Development of a Flat Plate Numerical Model with Experimental Validation
Authors: Villeneuve Eric , Volat Christophe , Ghinet Sebastian
Published: May 2020

The objective of this research project is divided in four parts: (1) to design a piezoelectric actuator-based de-icing system integrated to a flat plate experimental setup and develop a numerical model of the system with experimental validation, (2) use the experimental setup to investigate actuator activation with frequency sweeps and transient vibration analysis, (3) add ice layer to the numerical model and predict numerically stresses for different ice breaking with experimental validation, and (4) bring the concept to a blade structure for wind tunnel testing. This paper presents the first objective of this study. First, preliminary numerical analysis was performed to gain basic guidelines for the integration of piezoelectric actuators in a simple flat plate experimental setup for vibration-based de-icing investigation. The results of these simulations allowed to optimize the positioning of the actuators on the structure and the optimal phasing of the actuators for mode activation. A numerical model of the final setup was elaborated with the piezoelectric actuators optimally positioned on the plate and meshed with piezoelectric elements. A frequency analysis was performed to predict resonant frequencies and mode shapes, and multiple direct steady-state dynamic analyses were performed to predict displacements of the flat plate when excited with the actuators. In those steady-state dynamic analysis, electrical boundary conditions were applied to the actuators to excite the vibration of the plate. The setup was fabricated faithful to the numerical model at the laboratory with piezoelectric actuator patches bonded to a steel flat plate and large solid blocks used to mimic perfect clamped boundary condition. The experimental setup was brought at the National Research Council Canada (NRC) for testing with a laser vibrometer to validate the numerical results. The experimental results validated the model when the plate is optimally excited with an average of error of 20% and a maximal error obtained of 43%. However, when the plate was not efficiently excited for a mode, the prediction of the numerical data was less accurate. This was not a concern since the numerical model was developed to design and predict optimal excitation of structures for de-icing purpose. This study allowed to develop a numerical model of a simple flat plate and understand optimal phasing of the actuators. The experimental setup designed is used in the next phase of the project to study transient vibration and frequency sweeps. The numerical model is used in the third phase of the project by adding ice layers for investigation of vibration-based de-icing, with the final objective of developing and integrating a piezoelectric actuator de-icing system to a rotorcraft blade structure.
