Authors: Gültekin Alper , Acar Erdinç , Uğur Levent , Yıldız Aytaç , Serarslan Ulaş
Published: July 2021

Objectives: Calcaneal fractures are the most common tarsal fractures following a foot-ankle trauma. The Böhler’s angle is an important measurable angle before, during, and after surgery. In this study, we aimed to investigate correlation between Böhler’s angle, calcaneal strength, and subtalar joint stress using a finite element analysis (FEA).

Patients and methods: Between January 2016 and December 2016, computed tomography (CT) scans were used with MIMICS® software for FEA. The ankle and foot of a 23-year-old male person with a height of 180 cm and weighing 80 kg was modeled as reference. Raw coronal CT images were obtained in Digital Imaging and Communications in Medicine format with the resolution of 512X512 pixels and 0.3-mm slice intervals in 135 kV. The structures including tibia, fibula and 26 other bones (talus, calcaneus, cuboid, navicular, three cuneiforms, five metatarsals, and 14 components of phalanges), cartilage and ligamentous tissues were modeled to form ankle joint. After determining Böhler’s angle as 35 degrees for the reference model, a fracture line was created on calcaneus. Calcaneus was remodeled with the Böhler’s angle of 45, 40, 30, 25, 20, 10, and 0 degrees respectively. All models were transferred to ANSYS software for FEA and the loads on the lower extremities with normal posture were applied on models.

Results: Analysis of all models based in the reference model revealed that maximum tension values on calcaneus increased, while the Böhler’s angle decreased, indicating a statistically significant difference. The decreased Böhler’s angle indicated statistically significantly higher maximum tension values (p=0.04). Action force in subtalar joint was evaluated by comparing with the forces in reference model. The increased Böhler’s angle was found to be associated with statistically significantly decreased amount of load on subtalar joint. The decreased Böhler’s angle was related to the statistically significantly increased amount of load on subtalar joint.

Conclusion: Our study results suggest that decreased Böhler’s angle increases the possibility of subtalar arthrosis, although overcorrection of the Böhler’s angle seems not to increase the risk of subtalar arthrosis.

Banking institutions are one of the activator of a country's economy, namely business entities that collect funds from the public in the form of deposits and channel them back to the public in the form of credit. Efficient and optimal fund collection and distribution conducted by banks will be in line with the main objective of banking, namely achieving a level of profitability. Therefore, banks need to maintain profitability in order to remain stable or even increase. Return on Asset (ROA) is used as a proxy in measuring the profitability of a bank. A fairly complex problem in bank operational activities is liquidity management, due to the existence of funds managed by banks, most of which are short-term funds obtained from the public and can be withdrawn at any time. The purpose of this study is to obtain findings regarding the effect of capital adequacy ratio (CAR) and liquidity on profitability . The research method is to use quantitative research with secondary data, namely where the data that has been published with data collection using documentation techniques and analysis techniques using explanatory research methods. The results showed that capital adequacy ratio (CAR) and liquidity partially had a positive and insignificant effect on profitability while simultaneously had a significant effect on profitability.

FETAL ORIGIN OF ADULT DISEASE
Authors: Nguyễn Công Khanh
Published: July 2021

“Fetal origins of adult disease”, often called the “Barker hypothesis” after a large proportion data of Barker and colleagues in Southampton over the last decade, that adverse influences early in development, and particularly during intrauterine life, can result in permanent changes in structure, physiology, metabolism, which result in increased disease risk in adulthood. Many further studies have provided evidence for the hypothesis that size at birth is related to the risk of developing disease in later life. In particular, links are well established between reduced birthweight and increased risk of coronary heart disease, diabetes, hypertension and stroke in adulthood. The most widely accepted mechanisms thought to underlie these relationship are those of altered fetal nutrition, genetic–epigenetic links, fetal programming and fetal excess glucocorticoid exposure. It is suggested that the fetus makes physiological adaption in response to changes in its environment to prepare itself for posnatal life. The “Fetal origin of adult disease” hypothesis is attractive. It suggests that these diseases could be prevented by improving maternal health and fetal development

Published: July 2021

Forest biomass estimation is the central part of sustainable forest management to assess carbon stocks and carbon emissions from forest ecosystem. Sentinel-2 is state-of-art sensor with refined spatial and recurrent temporal resolution data. The present study explored the potential of Sentinel-2 derived vegetation indices for above ground biomass prediction using four regression models (linear, exponential, power and logarithmic). Sentinel-2 indices includes Global environmental monitoring index, transformed normalized difference vegetation index, normalized difference water index, normalized difference infrared index and red-edge normalized difference vegetation index. The performances of Sentinel-2 indices were assessed by simple single variable (index) based regression for GEMI, TNDVI, NDII, NDWI and RENDVI versus AGB values. Further, stepwise linear regression was also developed in which used all indices entered into stepwise selection and the best index was selected in the final model. Results showed that linear model of all indices performance best compared to the rest three models and R2 values 0.12, 0.39, 0.46, 0.44 and 0.37 for Global environmental monitoring index, transformed normalized. Vegetation index, normalized difference water index, infrared index and red-edge vegetation index, respectively. Normalized difference water index was considered the best index among five computed indices in simple linear as well as in stepwise linear regression, whereas rest of the indices were removed because they were not significant under the stepwise criteria. Further, the accuracy of normalized difference water index model was determined by root mean square error and final prediction model has 28.27 t/ha error for both simple linear and stepwise linear regression. Therefore, normalized difference water index was selected for biomass mapping and resultant biomass showed up to 339 t/ha in the study area. The resultant biomass map also showed consistency with global datasets which include global forest canopy height and global forest tree cover change maps. The study suggest that Sentinel-2 product has great potential to estimate above ground  biomass with accuracy and can be used for large scale mapping in combination with national forest inventory for carbon emission accounting.

Az egészségügyi rendszerek rezilienciája: elméleti keretek, gyakorlati megfontolások
Authors: Farkas Borbás Fanni , Gresz Miklós
Published: July 2021

Nemzeti és nemzetközi szinten is foglalkoztatja a szakértőket, hogy hogyan lehetséges az ellátórendszert talpra állítani egy, a rendszer működését megzavaró sokk után, milyen mérési módszerek, indikátorok segíthetik a folyamat pontos megismerését, esetleg hogyan lehetne felkészülni és előre jelezni egy újabb vészhelyzetet. A reziliencia kérdése a 2009-es gazdasági válság idején került fókuszba, azóta folyamatos érdeklődés tárgya, a koronavírus pandémia pedig kifejezetten aktuálissá teszi. Cikkünk célja az egészségügyi rendszerek rezilienciájával foglalkozó fő irodalmak áttekintése, a fogalom definiálása, a reziliens ellátórendszer ismérveinek, valamint az ezt erősítő és a vészhelyzetet leküzdő stratégiáknak a bemutatása. A reziliens egészségügyi rendszer úgy tud szembenézni különféle megrázkódtatásokkal, szerkezeti változásokkal, hogy nem veszíti el azt a képességét, hogy fenntartható módon a társadalom jóllétét szolgálja. A reziliencia képessége az egész egészségügy rendszer tulajdonsága, nem pedig egyetlen dimenziója. Az egészségügyi rendszer általános megerősítése sokat tesz a sokkokkal szembeni felkészülés érdekében. Az azonosított gyenge területek speciális fejlesztése pedig nemcsak a rendszer rezilienciáját, hanem a teljesítményét is javíthatja. A felkészültség önmagában még nem garantálja az alkalmazkodóképességet, ezért a sokk-kezelési stratégiák megléte szintén kritikus fontosságú. A bemutatott irodalmak több olyan stratégiát azonosítanak, amelyek segíthetik a rendszer alkalmazkodóképességének fejlesztését. Ezeket a magyar ellátórendszer erősítéséhez is ajánljuk.

In this paper, a p–n thin film NiO/ZnO heterojunction for a rectifier diode and a UV photodetector is prepared and characterized. Nickel oxide (NiO) and gallium-doped zinc oxide (ZnO:Ga) thin films are grown by RF magnetron sputtering and spray pyrolysis techniques, respectively. The crystal structure of the thin films is studied by the X-ray diffraction (XRD) method. The transmittance and reflectance are studied by UV–VIS spectroscopy. The p–n electrical parameters are estimated from current–voltage characteristics. The effects of duration of thermal annealing at 450oC on the characteristics of the NiO/ZnO:Ga device are evaluated. The non-annealed diode shows the best rectification coefficient of 105 at ±1 V. The p–n photodetection capability is studied under UV illumination. At a reverse bias of –3 V under 365-nm UV illumination, the device shows a current intensity of ~6.2 × 10-12 A. The observed increase in the reverse current intensity by about two orders of magnitude under a UV lamp with a spectral irradiance of 10 W m-2 μ m-1 indicates a promising application in UV light detection.
“Differing in Status, but one in Spirit”: Renegotiating the Boundaries of St. Brigit’s Double Monastery at Kildare
Authors: Bacola Meredith A.
Published: July 2021

The double monastery at Kildare, Ireland, developed from a confluence of holy sites and legends associated with St. Brigit into a major metropolitan center in the seventh century. One of the most interesting sources for this development’s apex remains Cogitosus’s Life of Saint Brigit, a collection of miracle stories immersed in the local landscape that reflect her community’s interests. A reassessment of the last three chapters of his Life, in conjunction with surviving material evidence in the landscape, will emphasize the ways in which hagiographical boundaries shaped Kildare’s development into a City of Refuge. It will argue that Cogitosus did not use ekphrasis, but delineated liminal boundaries functional to the dichotomies that Kildare was negotiating (male and female; lay and consecrated; community and pilgrims; Irish and Roman). Cogitosus’s Life provides a lens through which to view Kildare’s development into a major pilgrimage center.
“For-soþe I had leuar se ȝow be slayn”: Margery Kempe and the Biblical Susanna
Authors: Stavsky Jonathan
Published: July 2021

This article documents several unrecorded allusions to Susanna and the Elders (Dan. 13) in The Book of Margery Kempe, analyzes their function, and compares them with similar undetected echoes of the story in the Vita Offae Primi, attributed to Matthew Paris, John Whethamstede’s Registrum, Chaucer’s Franklin’s Tale, Hoccleve’s Series, the fabliau “Auberee,” and the chantefable Aucassin et Nicolette. Whereas some passages in the Book implicitly liken Kempe to Susanna, others contrast them. Yet the irony that emerges from the latter, for which her second scribe and confessor is probably responsible, does not turn her into a caricature of failed biblical virtue. On the contrary, it humanizes her and provides a glimpse of their intricate relationship.

Published: July 2021

The impact of Judith Fetterley's The Resisting Reader on the development of feminist literary criticism, particularly of the American literary canon, is well known. The parallels between Fetterley's late 1970s call for women to become resistant readers and the work of literary historians invested in the actual reading practices of women reading women's writing (in novels of the early American period) are at the heart of this personal reflection.

Authors: Muller Catarina , Rodrigues Catarina , Gouveia Manuel , Encarnacao Vítor , Olim Sousa Maria , Reis Miguel
Published: July 2021

Introduction: Colorectal cancer is ranked third among the most commonly diagnosed malignancies and second among the leading causes of cancer death in the world. However, only a few case reports are found in the literature regarding skin metastases originating from rectal cancer, which usually shows widespread disease and poor prognosis.

Case Report: A 68-year-old female patient presented with anterior chest wall pain and swelling and a history of progressive growing of the lesion for the last five months. Physical examination revealed a palpable 3 cm mass in the intermammillary area with mild inflammation of the surrounding skin. The lesion biopsy revealed moderately differentiated intestinal-type adenocarcinoma, suggesting metastasis of a colorectal primary cancer. Colonoscopy revealed an obstructive neoplasm of the rectum located 12 cm from the anal verge. Histology revealed a moderately differentiated adenocarcinoma as seen before in the skin lesion. The computed tomography (CT) scan also detected several secondary lesions on the liver.

Conclusion: Approximately 0.8% of the patients present with a skin lesion as the first indication of a silent internal malignancy, which is rare and carries a poor prognosis. Cutaneous metastases are considered as an advanced presentation of colorectal cancer, mostly managed with palliative care.

Authors: Vigoroso Lucia , Caffaro Federica , Cavallo Eugenio , Micheletti Cremasco Margherita
Published: July 2021

Aim of study: We tested the perceived quality in use of a prototype of a handling supporting device, developed through a user-centred design process intended for rear-mounted foldable rollover protective-structures (FROPSs).Area of study: The study was performed in the Province of Cuneo, which has the largest number of farms and the highest share of utilized agricultural area (UAA) in Piedmont Region, NW Italy.Material and methods: Three groups of users, novice-novice (NN), novice-expert (NE) and expert-expert (EE) were asked to raise two rear-mounted FROPSs: a traditional one and a second one equipped with a supporting device which consisted of a gas spring and a rod. A questionnaire has been used to record the perceived quality in use of both FROPSs (effort, physical discomfort, temporal demand and ease of use) and perceived usefulness and attitudes toward the adoption of the supporting device.Main results: All groups reported less physical effort, more stable postures, higher ease of use in handling the FROPS equipped with the supporting device; NN users, in particular, declared to be willing to adopt the supporting device in the future on their tractors when commercially available.Research highlights: Previous studies reported discomfort in operating the FROPS as the main cause of its improper use. A solution to improve FROPS reachability was developed and tested with users. Benefits were perceived by both novice users and expert users.
The IDEA Method for Assessing Irrigated Cereal Farms Sustainability in Algerian Arid Zones: Case of Ouargla Region (Oued M'ya)
Authors: Chaouch Saida , Djelfaoui Zineb , Kebaili Saida , Sandoval-Solis Samuel
Published: July 2021

The agricultural sector in the Saharan regions of Algeria has seen, since 1983, the development program of cereal cultivation irrigated by pivots thanks, essentially, to the availability of underground water resources which constitute its keystone. In Ouargla, these farms strongly supported by the public authorities and sustained by neo-farmers have marked progressions and regressions in space and in time, some have disappeared, others have undergone changes thus calling into question their durability. This research aims to assess the sustainability of these farms by the IDEA method (Sustainability Indicators of Farms Agricultural- Indicateurs de Durabilité des Exploitations Agricoles) based mainly on three scales; the agro-ecological scale, the socio-territorial scale and the economic scale. The analysis of 13 farms shows that this is an artificial production system, the installation of which is at great risk and depends heavily on the will of agricultural policies and entrepreneur-farmers. The economic scale seems to have the best score, however the profits generated by the farmers can be explained more by the consistent support of the State than by a tangible accounting balance. At the socio-territorial level, most of the components are failing, in particular a very low diversity of products and a strong lack of employment. The agroecological scale constitutes the limiting factor par excellence with an agriculture which consumes a lot of non-renewable water and energy and at the same time destroys the soil resource by the phenomenon of salinization. Thus the three scales are failing and the limiting factor par excellence is the environmental scale, the consideration of which is strongly recommended both nationally and internationally. This research also highlights the need for a revision of certain indicators of the IDEA method with a view to adapting it to the local context of arid zones and to the cereal agrosystem in Ouargla.

Public values and the use of genetic data

Three developments – technological advances in sequencing DNA data, the booming market for commercial DNA tests, and internationalization of collecting and sharing DNA data – are accelerating the use of DNA data worldwide. The authors discuss the impact of the increase in international and commercial use of DNA data and the way it puts public values (like privacy, autonomy, fairness) under pressure. When collecting, analyzing, and translating DNA data, privacy should be guarded, genetic discrimination has to be prevented, digital citizenship could be strengthened, and responsibilities for those applying DNA data should be strongly defined. By doing so, we can thrive for a future in which we make valuable use of DNA data.

Esta investigación tiene como objetivo conocer y analizar la autopercepción que el alumnado que inicia sus estudios en el grado de Maestro de Educación Primaria posee en referencia a su competencia electrónica para resolver problemas técnicos en el entorno digital, por lo que constituye un reto educativo relevante, puesto que se trata de un conocimiento imprescindible en la sociedad actual. El presente examen emplea una metodología descriptivo-interpretativa y ex post facto, utilizando para la recogida de datos un cuestionario dirigido al alumnado del primer curso del grado de Maestro de Educación Primaria de una facultad de Educación durante cuatro años consecutivos. A partir de los resultados obtenidos, se puede afirmar que estos docentes en formación se valoran a sí mismos como competentes. Sin embargo, no debemos olvidar que estos resultados solo muestran la autopercepción de los participantes y que en ellos se encuentran diferencias asociadas al sexo, es decir, los varones del estudio se valoran más competentes y parecen sentirse más seguros ante los problemas que puedan surgir con los dispositivos digitales que las mujeres.
Los ecos de la tradición en "La rosa" de Martín Adán
Authors: Soro Cuesta Esther
Published: July 2021

En la edificación del motivo poético de la rosa de Martín Adán (1908-1985) advertimos, esencialmente, la huella de la representación judeocristiana y mística del símbolo, que encarna los valores de infinitud y perfección. Esta visión es manifiesta en algunas obras adanianas, como el poema “La rosa” o los poemarios La rosa de la espinela y Travesía de extramares. En ellos, a través del empleo del símbolo floral, el autor emprende una búsqueda ontológica con el fin de aprehender la trascendencia. Sin embargo, su incapacidad para conseguirlo le permitirá comprender que la verdad del conocimiento se halla, paradójicamente, en la inefabilidad de la existencia humana.
Loxoro, de Claudia Llosa: crear una frontera propia con el lenguaje.
Authors: Wolfenzon Carolyn
Published: July 2021

En Loxoro (2012), Claudia Llosa explora el concepto de frontera en un nivel lingüístico, temporal y material, al llevar la narración a un territorio no demarcado físicamente, donde habitan las mujeres transexuales de Lima. Si es cierto que la frontera, además de ser un espacio que divide dos lugares, también es una herramienta de epistemologías hegemónicas que distinguen cualquier elemento definitorio de la identidad —el género, la lengua, entre otros—. Loxoro representa un cruce entre múltiples fronteras, donde la más difícil de atravesar es la del propio cuerpo. Sus protagonistas, mujeres transexuales, tienen una circulación restringida, ya que pueden ir y estar seguras solo en ciertos barrios y en ciertas horas. Existe un código no escrito en relación con las fronteras urbanas que las transexuales conocen bien, como cuerpos que, de acuerdo con Marjorie Garber (1997), producen ansiedad porque cuestionan la artificialidad binaria con la que se ordena el mundo. Así, se propone que Loxoro oscila entre dos niveles. En uno, muestra la violencia, la discriminación y los conflictos de un conjunto de mujeres transexuales en Lima mientras circulan por la ciudad; en el otro, empuja el espectador hacia un elevado nivel de reflexión sobre cómo funcionan el lenguaje y sus categorías: cómo solemos pensar y encasillar la realidad.

Published: July 2021

Heuristic Evaluation (HE) has proven to be important in the development of different computer systems but has not been incorporated in the development of eco-tourism smartphone applications. This results inusability issues that significantly affect user experience (UX) as discussed in literature. This study reports the HE in the design and development of Niranur Agro Farm (NAF) eco-tourism smartphone applications, which could improve UX. Eight experts participated in this study, utilizing the SMART mobile usability heuristic developed for mobile application and the severity rating scale to determine usability issues. The HE findings indicated that 22 usability issues were identified. One issue was rated 4 (catastrophe), four issues were rated 3 (major problem), twelve issues were rated 2 (minor problem) and five issues were rated 1 (cosmetics). Although there are issues rated as 4 and 3, the majority of the issues were considered to be minor (1 and 2 on the scale). Results indicated that it is crucial to incorporate HE into the design and development of the eco-tourism smartphone app to minimize the usability issues faced by users. It further validated that utilizing a specific heuristic for smartphone applications would ensure that all usability issues are correctly categorized and remedied.
Effect of Work Environment Factors on Willingness to Stay Level
Authors: Zakirah Fildzah Zatalini , Kusuma Hanson Endra
Published: July 2021

The quality of a workspace is influenced by the surrounding environment, called the work environment. A good work environment has a positive influence on comfort and willingness to stay. A comfortable workspace can improve performance and productivity. This study looked at the effect of work environment factors, both physical and non-physical, on someone’s willingness to stay while working in a workspace. This research used qualitative-quantitative methods. Explorative-qualitative methods were used to collect data about the work environment factors. Explanatory quantitative methods were used to see how these work environment factors influence the respondent’s willingness to stay level. Data collection in both stages of the study used an online questionnaire that was distributed freely (non-random sampling). From this study, 11 work environment factors that affect someone’s willingness to stay and intention to move were identified: social interaction, quality of visual interior, natural environment, spaciousness, artificial ventilation, glare, crowd, natural air, facility, air temperature, and humidity. The result of the analysis revealed that there were factors that strongly affect someone’s willingness to stay, factors that weakly affect someone’s willingness to stay, and factors that strongly affect someone’s intention to move.

Published: July 2021

O presente trabalho descreve um kit didático de controle de nível de baixo custo, para auxílio ao estudo de sistemas de controle. O kit desenvolvido, o qual é composto por elementos de hardware em conjunto com a plataforma de prototipagem Arduino© e associado ao software Simulink©, permitiu efetuar ensaios de identificação de sistemas de primeira ordem, obtendo-se um modelo matemático através de dados experimentais, e ensaios de controle em malha fechada. Através da analise dos resultados, percebeu-se que o modelo identificado apresentou resultados ótimos em regime permanente, porém pouco representativos em regime transitório. Como trabalhos futuros, foram sugeridos alguns ajustes no modelo para que o kit didático possa ser utilizado nas aulas.

A técnica de virtualização baseadas em contêineres vem sendo amplamente utilizada através da adoção de tecnologias como Docker e Kubernetes que permitem a criação e o gerenciamento de contêineres. Assim, o presente artigo utilizou o Prometheus e o Grafana para analisar a performance de um cluster Kubernetes executando a plataforma Dojot e recebendo dados de um simulador. Foi possível observar que o uso dos recursos de CPU e memória RAM são maiores nas máquinas Workers do cluster, onde quanto mais serviços da Dojot a máquina executa maior o consumo dos recursos. Concluiu-se que a utilização do Kubernetes juntamente com os seus recursos de gerenciamento e monitoramento são recomendáveis para aplicações que precisam se escaláveis.
