El láser como coadyuvante en el tratamiento de las úlceras
Authors: Diez Alcorta Eneritz , Ibarra Diez Naiara
Published: July 2019

Entre el 75% y el 80 % de las úlceras de la extremidad inferior son de etiología venosa. Además, constituyen un gasto económico sanitario elevado , lo que nos lleva a plantear la necesidad de encontrarles una solución costo-efectiva. Las úlceras venosas tratadas con láser de baja potencia evolucionan satisfactoriamente en un corto espacio de tiempo, lo que demuestra la efectividad de dicho tratamiento aunque todavía no hay suficiente evidencia que avale su uso.El principal objetivo de este estudio era mostrar la eficacia del láser en el tratamiento de úlceras de difícil cicatrización. Para ello, se presenta el caso de una mujer que presentaba úlceras venosas de 5 años de evolución en ambas extremidades inferiores que no habían mejorado con los cuidados de enfermería habituales.Tras uno y seis meses respectivamente de tratamiento conjunto enfermería-fisioterapia, ambas lesiones cicatrizaron.
Enfermedad cardiovascular y riesgo metabólico
Authors: López-Pardo Martínez Mercedes , Estepa Luna Maria José
Published: July 2019

Las enfermedades no transmisibles son responsables de cinco de cada diez problemas de salud en el mundo. Dentro de estas, las enfermedades cardiovasculares constituyen una verdadera epidemia a nivel mundial. Según el informe del Instituto Nacional de Estadística sobre las causas de defunción en nuestro país, la enfermedad cardiovascular sigue situándose como la primera causa de muerte representando el 29,2% del total de fallecimientos lo que la sitúa por encima del cáncer (27,5%) y de las enfermedades del sistema respiratorio (11,4%.).

Las tasas de mortalidad ajustadas por edad de España para el total de las enfermedades del sistema circulatorio y para la enfermedad isquémica del corazón son relativamente más bajas que las de otros países occidentales. En cuanto a la mortalidad por enfermedad cerebro vascular España ocupa una posición intermedia-baja. Las razones de la baja mortalidad coronaria de España no se conocen bien, pero tradicionalmente se ha considerado que su dieta y, más recientemente, otros hábitos de vida como la actividad física, pueden contribuir a ello.

Cuidados de Enfermería dirigidos a una paciente con Insuficiencia Venosa Crónica. A propósito de un caso
Authors: Pérez Roca Antonia María
Published: July 2019

La Insuficiencia Venosa Crónica es una patología progresiva, la cual es más prevalente entre el sexo femenino. Ciertos estudios demuestran que la enfermedad venosa altera la movilidad, el sueño, provoca efecto psicológico negativo y una disminución de la calidad de vida del paciente. Se presenta el caso clínico de una paciente de 65 años con diver-sas patologías, entre ellas Insuficiencia Venosa Cónica, que presenta baja adherencia terapéutica, sobrepeso, problemas de autoimagen, disconfort y déficit de conocimientos. El objetivo planteado fue proporcionar cuidados enfermeros que aporten al paciente conocimientos sobre su enfermedad, aumenten la adherencia terapéutica a su tratamien-to y mejoren su autoimagen y confort. Gracias a una adecuada planificación de cuidados, la paciente expresó gran satisfacción tras ampliar sus conocimientos y habilidades de autocuidado. Además presentó cambios significativos en su piel, mostró mejoría en su descanso y mayor aceptación hacia su imagen. Como conclusión, la educación para la salud en el paciente crónico es esencial para lograr un adecuado automanejo de su enfermedad y, así, aumentar la satisfacción con su proceso de salud.
¿Cuánto saben sobre heridas crónicas los estudiantes de Grado de Enfermería de la Comunidad de Madrid?
Authors: Sánchez Lluch Cristina , Martín Álvarez Marta , Garrido Romero Luis Ernesto
Published: July 2019

Una herida representa la pérdida de la continuidad de la piel. Las heridas crónicas son una importante causa de morbilidad y mortalidad en todo el mundo, y pueden producirse por múltiples causas. La edad, fármacos consumidos por el paciente, tabaquismo, la malnutrición, obesidad, sedentarismo, situación sociofamiliar, patologías asociadas y tratamiento inadecuado de la herida son factores que van a repercutir negativamente en la cicatrización adecuada. El proceso de la cicatrización es el resultado de una interacción compleja entre los factores del paciente y de la herida, el tratamiento empleado y los conocimientos y habilidades de los profesionales sanitarios. Cuando se supera el periodo de 6 semanas las heridas comienzan a considerarse crónicas. A pesar de los esfuerzos por implementar la evidencia científica, en la práctica de enfermería aún se observa una separación entre lo académico y lo clínico; esta separación viene dada sobre todo por la actitud del profesional, la falta de recursos y apoyo que impiden que la investigación se utilice para tomar decisiones en la práctica clínica. El objetivo de este estudio era evaluar el conocimiento de los alumnos de cuarto de enfermería sobre heridas. Se realizó un estudio descriptivo y transversal, durante el mes de abril de 2018, entre estudiantes de 4º de Enfermería de la Comunidad de Madrid. Se elaboró una encuesta ad hoc que fue difundida por medios telemáticos entre estudiantes de universidades públicas y privadas. Para el análisis de resultados se llevó a cabo un análisis estadístico descriptivo con cálculo de frecuencias absolutas y relativas para las variables cualitativas y media con desviación estándar para las variables cuantitativas. El estudio estadístico se realizó con el programa Access. Los estudiantes entrevistados tienen un nivel de conocimientos insuficiente, pero sería necesario llevar a cabo estudios adicionales que confirmen estos resultados. Nuestro compromiso es llevar a cabo un estudio más amplio, cuando nuestras competencias investigadoras lo permitan, que además ayude a identificar posibles mejo-ras en la formación que reciben los alumnos en este campo.

Authors: Riballo Cortés Raquel , Estepa Luna Maria José , Moya González Javier
Published: July 2019

La diabetes mellitus engloba un grupo de trastornos metabólicos caracterizados por la presencia de glucemia elevada. Sus complicaciones vasculares generan una disminución del flujo sanguíneo en las extremidades inferiores, lo que unido a la afectación neuropática da lugar al pie diabético con úlceras de difícil cicatrización.El conocimiento de la enfermedad de base (diabetes) es crucial para la prevención y tratamiento de las complicaciones del pie diabético.El objetivo del estudio fue conocer el grado de conocimiento que tienen los pacientes diabéticos acerca del cuidado de los pies y sus complicaciones, la disposición de estos a cambiar sus hábitos para mejorar su calidad de vida y, por último, las medidas que han adoptado en la práctica para evitar la aparición de ulceras. Se realizó un estudio descriptivo en pacientes diabéticos con ulceras atendidos en la Unidad de pie Diabético y Úlceras Vasculares del Hospital Universitario Reina Sofía de Córdoba.La importancia que tiene el conocimiento del cuidado de los pies para prevenir las úlceras en los pacientes diabéticos es un hecho ampliamente aceptado, aunque puede haber otras variables que incidan en la aparición de complicaciones. El resultado del estudio muestra que más de dos tercios de los pacientes diabéticos estudiados tiene un conocimiento intermedio/alto sobre las implicaciones que tiene su enfermedad en el desarrollo de complicaciones a nivel del pie. Se han puesto de relieve las deficiencias en el conocimiento y el autocuidado de los pies en los pacientes estudiados y la necesidad de instaurar un programa educativo efectivo para reducir las complicaciones de pie diabético.
Enjeux et impacts des réseaux sociaux pour les agences de voyages marocaines

Published: July 2019

Les agents de voyages assistent aux plusieurs mutations tirées par les nouvelles technologies, l’économie de partage et l’innovation disruptive. De nouveaux acteurs investissent le marché profitant d’un grand décalage entre l’offre et la demande, du manque de contrôle et d’un cadre juridique qui a du mal à suivre les diverses mutations. Cette situation profite au secteur informel qui grignote des parts de marché importantes grâce à une forte présente dans les réseaux sociaux. Ces médias seraient donc un booster et un amplificateur du secteur parallèle touristique. Cet article analyse ces mutations et les enjeux pour les agences de voyages marocaines.
Consumer perception of insects in non-food products
Authors: Lenaerts M. , Meersman F. , Verheyen G.R. , Van Miert S.
Published: July 2019

In order to evolve towards a green and biobased economy, the use of insects can play a vital role for the management of organic waste and its conversion into biomass. The larvae of black soldier fly (Hermetia illucens), a high fat containing insect, appear to hold interesting opportunities for companies active in oleo chemistry as well as companies that process the fats and derived products (such as surfactants) into end products, such as detergents, household cleaning products, personal care products and cosmetics. When introducing new green products like these to consumers, an understanding of the perception of insect-based products is necessary to choose appropriate marketing strategies to overcome innovation resistance. Due to the lack of research on this subject, the purpose of this study is to develop an initial understanding of the consumer perception and to explore the factors driving and hindering the adoption of insect-based products. The majority of studies on the subject of insects, is focused on applications in food. Our study aims to fill an existing gap, by focussing on non-food products. A mixed method design was used and consists of a literature study, and a qualitative and quantitative data collection and analysis. The results indicate that both novelty seekers and risk avoiders are willing to try insect-based products, but barriers vary per product category. This study is part of the INFACT project, in which green surfactants, based on black soldier fly fats are synthesised and implemented in technical applications.

Published: July 2019

BACKGROUND AND OBJECTIVE:

To describe retinal and choroidal findings in different stages of acute posterior multifocal placoid pigment epitheliopathy (APMPPE).

PATIENTS AND METHODS:

Retrospective, noncomparative case series studied by fundus biomicroscopy, fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA), spectral-domain optical coherence tomographic (SD-OCT), and swept-source OCT angiography (SS-OCTA).

RESULTS:

Six eyes of three patients with bilateral APMPPE were included. FAF showed multifocal, branched patches of hyperautofluorescence with areas of hypoautofluorescence; FA disclosed early hypofluorescence, with late-phase hyperfluorescence; ICGA showed early and late-phase hypofluorescence. SD-OCT imaging revealed bilateral retinal thinning, external limiting membrane (ELM) disruption, and severe alteration of the photoreceptor-retinal pigment epithelium complex. SS-OCTA showed widespread multiple dark spots in the choriocapillaris in Cases 1 and 2. Rarefaction and voids in the vascular texture were also detected in the deep plexus, unlike in Case 3, where the lesions were smaller and earlier, suggesting that retina vasculature may be affected after the choriocapillaris obstruction.

CONCLUSIONS:

APMPPE may result from a distinct focal ischemia in the choriocapillaris, and OCTA allowed the authors to localize exactly all the placoid lesions and monitor the areas of absent fluid signal.

Evaluating the Effect of Intravitreal Ranibizumab on Retrobulbar Hemodynamics by Color Doppler Ultrasonography in Neovascular AMD
Authors: Raza Sabri , Ergun Sule Berk , Toklu Yasin , Cakmak Hasan Basri , Ipek Ali , Cagil Nurullah
Published: July 2019

BACKGROUND AND OBJECTIVE:

To evaluate changes in retrobulbar blood flow by using color Doppler ultrasonography (CDUS) after intravitreal ranibizumab injection in patients with neovascular age-related macular degeneration (AMD).

PATIENTS AND METHODS:

Eighteen patients who had undergone intravitreal ranibizumab (0.05 mg/0.05 mL) injection due to choroidal neovascular membrane (CNVM) were included in the study. Contralateral eyes of the patients were also analyzed. Peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI), and resistivity index (RI) were measured from the ophthalmic artery (OA), central retinal artery (CRA), lateral posterior ciliary artery (LPCA), and medial posterior ciliary artery (MPCA) for all patients pre-injection, and at 1 day, 1 week, and 1 month after ranibizumab injection.

RESULTS:

The mean age of the 18 patients included in the study was 66.94 years (± 8.3 years). Of these 18 patients, eight were female and 10 were male. After Bonferroni's correction for multiple comparisons was carried out, there were significant differences only in some values of LPCA; these included the decrease in EDV and an increase in PI values of LPCA between the pre-injection and post-injection of the first month measurements in uninjected eyes (P= .002,P= .002), and a decrease in PI value of LPCA between post-injection first day and first week measurements in injected eyes (P= .004). There were no statistically significant differences in other parameters.

CONCLUSION:

Ocular blood flow velocities may change after intravitreal ranibizumab injection in patients with CNVM.

College choice, selection, and allocation mechanisms: A structural empirical analysis
Authors: Carvalho José Raimundo , Magnac Thierry , Xiong Qizhou
Published: July 2019

We use rich microeconomic data on performance and choices of students at college entry to analyze interactions between the selection mechanism, eliciting college preferences through exams, and the allocation mechanism. We set up a framework in which success probabilities and student preferences are shown to be identified from data on their choices and their exam grades under exclusion restrictions and support conditions. The counterfactuals we consider balance the severity of congestion and the quality of the match between schools and students. Moving to deferred acceptance or inverting the timing of choices and exams are shown to increase welfare. Redistribution among students and among schools is also sizeable in all counterfactual experiments.
Phytosociological description of Fagus sylvatica forests in the Raša Valley (SW Slovenia) / Fitocenološki opis bukovih gozdov v dolini Raše (jugozahodna Slovenija)

AbstractThe paper discusses and supplements the knowledge of the phytosociological composition of Fagus sylvaticaforests in the Raša Valley, on the northeastern edge of the Karst, or more specifically, in the area between the plateau of Vrhe, the Senožeče lowland and the Karst. They are classified into two associations, Seslerio autumnalis-Fagetumand Hacquetio-Fagetum. A new subassociation (-lamietosum orvalae) and a new geographical subvariant (subvar. geogr. Helleborus istriacus) were determined for the association Hacquetio-Fagetum. Although they occupy small areas these beech forests are an important part of the predominantly oak and hop hornbeam forest vegetation of the Karst, constituting a Natura 2000 habitat type Illyrian Fagus sylvaticaforests (Aremonio-Fagion). They are threatened by climate change and excessive logging.Key words: phytosociology, synsystematics, Aremonio-Fagion, Hacquetio-Fagetum, Raša, Kras, SloveniaIzvlečekDopolnili smo vednost o fitocenološki sestavi bukovih gozdov v dolini Raše, na severovzhodnem robu Krasa, natančneje med planoto Vrhe, Senožeškim podoljem in Krasom.

Disrupting the U.S. National Security Through Financial Cybercrimes
Authors: Nobles Calvin
Published: July 2019

The U.S. financial sector is the bedrock of the economic health and strategic advancement. As a critical infrastructure, the financial sector continuously faces cyber-attacks and other nefarious activity. The financial sector is undergoing a technological explosion and forcing banks and financial institutions to implement cutting edge technologies. Even though technological breakthroughs are yielding competitive advantages; consequently, the same technologies are more prone to cyber-attacks stemming from technologically-induced vulnerabilities. The integrative and hyperconnected state of the financial industry and the domestic and global financial ecosystems are highly centralized and vulnerable to sophisticated cybersecurity threats, human factors, social engineering, credit card fraud, and online banking schemes. Any attempts to degrade, disrupt, or deny vital services and transactions in the financial industry could be conceived as an infringement and blockade of the U.S. global powers.
Is Ubiquitous Technology for Needs Data Management a Game Changer in Humanitarian Arena?
Authors: Sapkota Punya Prasad , Siddiqi Kashif
Published: July 2019

One in every 70 people around the world is caught up in a crisis (natural disasters, conflict, climate change, etc.) and urgently needs humanitarian assistance and protection according to the OCHA. The humanitarian community assists millions of people every year based on emerging humanitarian needs. Most of the time, the conditions inside the countries, once the humanitarian needs data is collected, are not very conducive and required simple ways to collect data like paper-based data collection with simple questions. This data is later entered into a database or spreadsheet using rigorous and time-consuming data entry efforts. Dynamic changes in needs of people; numbers of partners involved; the complexity of evolving processes; and emerging technologies over time has led to a change in processes for data collection and management. This article is an attempt to capture humanitarian data collection best practices and the use of different technologies in managing data to facilitate humanitarian needs assessment processes for the Syria crisis.
Lecturers' Perceptions of the Use of Learning Management Systems
Authors: Gani Faiza , van den Berg Geesje
Published: July 2019

Learning management systems (LMSs) provide possibilities to facilitate online teaching and learning; to create communities of inquiry, support dialogue and collaborative learning; and reduce students' sense of disconnectedness in distance learning. Nevertheless, studies show that LMSs are often under-utilized. This article reports on lecturers' perceptions of the use of an LMS in an open distance learning (ODL) institution in South Africa. The authors used a phenomenological case study and followed a qualitative approach. Interviews were conducted with ten lecturers from eight academic departments. The results reveal that participants used the LMS mainly for administration and to a lesser extent for teaching and learning, with a limited presence of a community of inquiry. The challenges reported by interviewees had poor access to the internet, a lack of skills, fear, and workload. The study suggests that if lecturers used the LMS for teaching and learning, it will yield many benefits for students.

Published: July 2019

Frequent item-set mining has been exhaustively studied in the last decade. Several successful approaches have been made to identify the maximal frequent item-sets from a set of typical item-sets. The present work has introduced a novel pruning mechanism which has proved itself to be significant time efficient. The novel technique is based on the Artificial Cell Division (ACD) algorithm which has been found to be highly successful in solving tasks that involve a multi-way search of the search space. The necessity conditions of the ACD process have been modified accordingly to tackle the pruning procedure. The proposed algorithm has been compared with the apriori algorithm implemented in WEKA. Accurate experimental evaluation has been conducted and the experimental results have proved the superiority of AFARTICA over apriori algorithm. The results have also indicated that the proposed algorithm can lead to better performance when the support threshold value is more for the same set of item-sets.
The Influence of Technological Parameters on Drawing Force at Cold Drawing of Steel Tubes Using FEM Simulation
Authors: Kapustová Mária , Sobota Róbert , Necpal Martin
Published: July 2019

The process of cold die drawing of tubes is ranked among frequently used methods of production of seamless tubes and is performed in drawing tool which is characterized by simple design. Shape and dimensions of the drawing tool depend on tube reduction degree, i. e. on original diameter of initial tube and final internal diameter of the tube. Tube wall thickness is not determined by any tool. The technology of cold die drawing of tubes is influenced by various process parameters, i.e. geometry of the die itself, strain degree and strain rate, force conditions, conditions of friction, method of lubrication and the type of used lubricant. The contribution is concerned with evaluation of influence of the selected process parameters using FEM simulation. Designed graphs illustrate the impact of coefficient of friction and reduction cone of drawing tool on the size of drawing force.
Infrared Emittance and Electrical Properties of Ce4+ Doped Sm0.5Sr0.5CoO3 Ceramics
Authors: Chen Le , Zhan Wang , Sun Hui Min , Gu Zhao Zhan
Published: July 2019

A series of Sm0.5Sr0.5CoO3-CeO2 ceramics formed by solid state-reaction method have been systematically investigated. The effects of doping the Sm site of Sm0.5Sr0.5CoO3 with Ce4+ on the structural, spectral reflectance, and thermal radiation properties were also explored. The modification of the initial phase takes place can be ascribed to the dissolution of Ce from initial CeO2 into the perovskite structure. The conductivity behavior depends critically on the Ce doping level, as was demonstrated that the recombination of holes (from Sm0.5Sr0.5CoO3) and electrons (from ceria ion) could decrease electrical conductivity. Sm0.5Sr0.5CoO3-CeO2 ceramics showed continuously adjustable conductivity and infrared emittance, opening up possible applications in solar thermal conversion or thermosensitive conductivity.

Published: July 2019

The objective of this study was to compare the cytotoxicity of a domestically-made light-cured orthodontic adhesive to a commercial adhesive, Transbond XT (3M Unitek, USA). An in-house orthodontic adhesive composed of a filler 60-70 weight % and a monomer ratio (BisGMA:TEGDMA) of 6:4 with 0.5% of photoinitiator was mixed. The potential cytotoxic effect of this experimental and a control adhesive was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay according to ISO 10993-5: 2009(E). The L929 cell line was grown in 96-well tissue culture plates (1x105 cells/mm3). Thin cured-resin discs of each material weighing 0.4 gram were prepared and incubated for 1, 3, 5, 7, 14, and 30 days in Dulbecco’s modified Eagle medium (DMEM) at 37°C and 95% humidity with 5% CO2. The percentage of cell viability was reported by descriptive statistics. The result showed that the cell viability of the experimental adhesive was higher than Transbond XT in all measured periods. The cytotoxicity of both the adhesives gradually decreased with the progression of time. In conclusion, the in-house adhesive showed a good biocompatibility since the first day following polymerization. On the other hand, Transbond XT started with a cytotoxic potential, then, turned to be non-cytotoxic after 5 days of curing.
Abnormal Motor Response Associated With Concussive Injuries: Biomechanical Comparison Between Impact Seizures and Loss of Consciousness
Authors: Cournoyer Janie , Hoshizaki T. Blaine
Published: July 2019

Context

Loss of consciousness (LOC) and impact seizures associated with concussion represent different clinical presentations of concussion; however, they are often investigated and treated similarly. The biomechanical parameters differentiating these 2 distinct signs of injury are poorly described.

Objective

To differentiate between cases of concussions with LOC and those with impact seizures by comparing the impact velocity, peak linear and peak rotational acceleration, as well as brain tissue deformation in the cerebral cortex, white matter, brainstem, cerebellum, thalamus, and corpus callosum.

Design

Descriptive laboratory study.

Patients or Other Participants

Elite American football players who sustained an LOC (n = 20) or impact seizures (n = 21).

Main Outcome Measure(s)

Impact velocity, peak linear and peak rotational acceleration, maximum principal strain, cumulative strain damage measure at 10%, and strain rate (SR).

Results

The SR in the cerebral white matter was greater in the LOC group than in the impact-seizure group. Similar trends were observed for SRs in the cerebral cortex, brainstem, and corpus callosum. No differences were present between groups for the other variables in this study.

Conclusions

A lower SR in certain brain regions helps to explain why motor function is preserved and can be observed in patients with impact seizures versus LOC from concussive injuries.
Testing the inescapable network of mutuality: Albert Luthuli, Martin Luther King Jr and the challenges of post-liberation South Africa
Authors: Boesak Allan A.
Published: July 2019

The assassination of Martin Luther King Jr, 50 years ago on 04 April 1968, has been recalled in the United States with memorial services, conferences, public discussions and books. In contrast, the commemoration in 2017 of the death of Albert John Mvumbi Luthuli, 50 years ago on December 1967, passed almost unremarked. That is to our detriment. Yet, these two Christian fighters for freedom, in different contexts, did not only have much in common, but they also left remarkably similar and equally inspiring legacies for South Africa, the United States and the world in the ways they lived their lives in complete faith commitment to ideals and ways of struggle that may guide us in the ongoing struggles to make the world a more just, peacable and humane place. For South African reflections on our ethical stance in the fierce, continuing struggles for justice, dignity and the authenticity of our democracy, I propose that these two leaders should be considered in tandem. We should learn from both. This article engages Martin Luther King Jr’s belief in the ‘inescapable network of mutuality’, applies it to the struggle for freedom in South Africa and explores the ways in which South Africans can embrace these ethical ideals in facing the challenges of post-liberation.
Savings and economic growth in South Africa: A multivariate analysis
Authors: Amusa Kafayat
Published: July 2019

Growth theories highlight the importance of domestic savings for Economic growth. The savings and growth literature points generally to a positive growth effect of domestic savings. For a country like South Africa, where the level of domestic saving is low, the question of the role of savings in economic growth becomes critical. An understanding of the contribution of the different forms of savings in an economy to its economic growth is important, especially to be able to make the proper policy addresses. This paper applies cointegration analysis within a multivariate framework to establish the effect of household, government and corporate savings on economic growth in South Africa. The result indicates that corporate saving has a significant positive relationship to growth in both the long and short run, while household and government saving have no significant impact on growth. There is need for policies that increase the level of domestic savings and also a need to address government policies that impact on both public and household savings rate.
Socially responsible investing returns: Evidence from South Africa, 2004-2012
Authors: Chawana Munyaradzi
Published: July 2019

A number of researchers have sought to test the theoretical prediction of Modern Portfolio Theory that asserts that Socially Responsible Investing (SRI) under-performs conventional investing. In contrast to the majority of literature, which focuses on comparing SRI funds’ performance to conventional funds, this study compares the performance of South Africa’s JSE SRI Index to the performance of local conventional market indices in the period 2004-2012. Using Sharpe ratios, the results of the study indicate that in comparison to conventional indices, the JSE SRI Index generally exhibits an inferior risk-return trade-off in both bull and bear market conditions. Furthermore, spanning tests based on the single-factor Capital Asset Pricing Model provide evidence that the JSE SRI Index is only likely to earn similar risk-adjusted returns to the Synthetic Conventional Index (a self-constructed index tracking non-overlapping conventional stocks). However, if the assumption of a non-restricted investment universe for a non-socially conscious investor is considered, there is a risk-adjusted return penalty for investing in the JSE SRI Index.
Factors which may predict successful rehabilitation in patients who have undergone coronary artery bypass surgery: A pilot study
Authors: Eales C. , Stewart A.
Published: July 2019

A study was conducted to determine the factors which may predict the successful outcome of rehabilitation in patients who had undergone coronary artery bypass surgery.Rehabilitation was considered successful if the patient experienced an improved quality of life and had accepted the responsibility for his/her own rehabilitation.Ten patients who had undergone coronary artery bypass surgery one year ago, were selected from the Cardiac Rehabilitation Unit of the Johannesburg Health and Housing Department.The outcome of rehabilitation was determined in these ten patients by judging their improvement in quality of life and their acceptance of self-responsibility.This was done by administering a questionnaire to the patients and their spouses which covered aspects of compliance to a programme to modify risk factors, the patients' ability to manage stress, their fitness and obesity profiles and their exercise habits.From this study the authors concluded that the acceptance of self-responsibility for rehabilitation is an important factor in the outcome of successful rehabilitation.

A virtual logbook for the documentation of a continuously changing archaeological site: the San Clemente site in Albenga (Italy)
Authors: Previtali Mattia
Published: July 2019

Cultural and built heritage is nowadays recognized as a value not only in the socio-cultural field but also as an important economic driver. However, this non-renewable resource is more and more threatened by both external and internal factors and only by raising awareness on the vulnerability of cultural heritage we can lead to a real involvement of citizen to heritage site protection. In this sense, Virtual Museums (VMs), and more in general virtual technologies, can have a primary role to attract tourists and citizens. Indeed, VMs by presenting cultural concepts by using amusing and engaging techniques may reach younger generations in an easier way. In this paper, the specific case of the San Clemente archaeological site (Albenga, Italy) is addressed. Being the site in the riverbed of the Centa, it undergoes frequent flooding events causing continuously new damages to the archaeological site. The development of a virtual logbook of the site is presented along with the pre-processing steps that are necessary for the preparation of the published material. The logbook is addressed on one side to professionals (i.e. archaeologists and practitioners in cultural heritage) with the main aim of providing a tool for quick damage assessment. On the other side, a mobile app is on development for tourists and citizens allowing virtual exportation of the site and providing informative contents about it.

Highlights:

Virtual museums and virtual environments are fundamental tools to raise awareness about the vulnerability of archaeological sites.

This paper presents the development of a virtual logbook, that can be used by experts and tourists, for the archaeological site of San Clemente (Albenga).

Integration of data coming from different sources is rendered into a web environment that can be easily accessed from both desktop and mobile devices.
Enhancing heritage fruition through 3D virtual models and augmented reality: an application to Roman artefacts
Authors: Gherardini Francesco , Santachiara Mattia , Leali Francesco
Published: July 2019

The spatial characteristics of museum exhibitions may limit visitors’ experience of the artefacts on display. In the case of large artefacts, limited space may affect their whole visualization, or inhibit the visualization of the details farthest from the observer. In other cases, the storage of artefacts in distant sites (museums or archaeological areas) may influence their knowledge process or the possibility for comparative analysis. Moreover, the precarious state of preservation of some artefacts, with damaged or missing parts, makes it difficult to perceive their original appearance. To overcome these limitations, we propose an integrated approach based on 3D virtual models and Augmented Reality (AR) to enhance the fruition of artefacts, improving their visualization, analysis and personal/shared knowledge, also by overcoming space and time constraints. The final AR application is an easily accessible tool for most users from a mobile device, used both inside and outside museums, opening new perspectives for fruition. The framework encourages the use of free and open source software and standard devices, to maximize their dissemination and exploit the potential of such technologies, which is far greater than current use in the cultural heritage field. Selected case studies to test and validate the integrated framework are proposed, dealing with some Roman artefacts found in the area of Modena (Italy). The first is a Roman floor mosaic, found in Savignano sul Panaro (near Modena) in 2011, of which less than half of its original 4.5 x 6.9 m surface is preserved. The others are two Roman funerary lion sculptures: the first is one of two lions flanking the main door of Modena Cathedral, and the second, well-preserved but damaged, is housed in the Museo Lapidario Estense of Modena. Finally, the application was tested by museum experts and visitors both inside and outside the museum, and positively assessed.

Highlights:

Digital practice is not understood as a prerogative of a small number of people, but as a tool to guarantee and expand artefact fruition, using standard devices and free and open source software.

Experimentation of new settings to re-contextualize artefacts and establish possible links among them, offering engaging and customized experiences to improve their accessibility and enjoyment.

Promotion of artefact fruition not only in but also outside museums, such as in a classroom or an open and shared space, opening to new approaches in the fruition of cultural heritage.

A problemática relacionada aos recursos hídricos tem sido palco de debates devido a constante deterioração da qualidade da água e aumento de sua demanda. Assim, este estudo objetivou analisar a influência do uso e ocupação da terra na qualidade da água dos principais cursos de água da Área de Proteção Ambiental (APA) Itupararanga (SP). Para tanto, foram realizadas análises dos principais parâmetros e índices de qualidade das águas, bem como o mapeamento do uso e ocupação da terra. Os resultados revelaram que as condições de esgotamento sanitário dos municípios da APA Itupararanga e as classes de usos agrícolas estão impactando negativamente na qualidade da água.
Leituras geográficas em Oliveira Vianna
Authors: Cirqueira Diogo Marçal
Published: July 2019

O objetivo desse texto é analisar as discussões do pensador brasileiro Oliveira Vianna (1883-1951) sobre raça e meio na sociedade brasileira. Busca-se compreender como esse autor tenta equacionar os dois problemas que envolviam a formação de uma nação brasileira “desenvolvida” e “civilizada” no início do séc. XX: a população composta majoritariamente por “raça inferior” e as determinações impostas pelo meio tropical tórrido e degenerador. Oliveira Vianna enxergava na resolução dos problemas da raça e do meio tropical a única saída viável para o país. Acreditando na superioridade “ariana”, o autor enfatiza a necessidade de inserir no território brasileiro população proveniente da Europa. É nesses termos que o autor produz um discurso geográfico, pois, estabelece discussões sobre a relação homem-meio e apresenta uma proposta de planejamento regional para a “alocação racional” dos “tipos arianos” para os meios naturais adequandos a sua racialidade. É importante compreender o discurso geográfico de Oliveira Vianna pois, ele influenciou uma série de geógrafos que buscaram analisar as diferenças regionais e o povo brasileiro.
Diagnóstico ambiental da bacia hidrográfica do rio Mampituba, região sul do Brasil, utilizando a matriz FPEIR

Published: July 2019

O objetivo deste trabalho foi diagnosticar a situação dos recursos hídricos da Bacia Hidrográfica do Rio Mampituba (BHRM), região sul do Brasil. Utilizou-se o método da matriz de indicadores socioambientais FPEIR (Força Motriz, Pressão, Estado, Impacto e Resposta). Após síntese e classificação dos dados, os mesmos foram mapeados por sub-bacias. Verificou-se que a sustentabilidade ambiental da maior parte da BHRM encontra-se em situação regular. A principais atividades geradoras de pressão são agricultura, indústria e urbanização, mas de modo geral a pressão antrópica é baixa. Entretanto, constata-se a vulnerabilidade da BHRM pela falta de infraestrutura de abastecimento de água e saneamento e de ações de monitoramento, proteção e gestão ambiental, ou seja, pela escassez de medidas de resposta adequadas.
Evidências empíricas sobre a relação entre o PIB e os gastos públicos nos municípios paranaenses: uma abordagem espacial
Authors: Pinto Michele Aparecida Nepomuceno , Parré José Luiz
Published: July 2019

Este artigo é um estudo empírico sobre a relação existente entre gastos públicos e a formação do PIB per capita nos municípios paranaenses para o ano de 2010. Para tanto, foi utilizado um modelo econométrico espacial com o objetivo de verificar se essa relação entre gastos públicos e PIB per capita possui efeitos de transbordamento para os demais municípios do Estado. Os resultados encontrados mostram que as despesas têm impacto relevante e positivo sobre o PIB per capita dos municípios, bem como possuem externalidade espacial. Conclui-se que os governos municipais devem procurar promover o crescimento do PIB alocando seus gastos em áreas que busquem garantir uma melhor estrutura de investimento, bem como deve haver uma coordenação entre municípios vizinhos de forma que o crescimento de uma cidade promova o crescimento das cidades das redondezas, o que leva a um ganho para a região toda.
The formation of Middle and Upper Pleistocene terraces (Übergangsterrassen and Hochterrassen) in the Bavarian Alpine Foreland – new numeric dating results (ESR, OSL, 14C) and gastropod fauna analysis

Abstract. Until now, reliable chronological classifications based on numerical ages for many Pleistocene fluvial deposits in the Alpine Foreland were rare. In this study, new numeric data (ESR, OSL, 14C) from Middle and Upper (Late) Pleistocene Hochterrassen (high terraces) and Übergangsterrassen (transitional terraces) in the Bavarian Alpine Foreland are presented. The dating results imply that the Hochterrassen gravel sensu stricto were deposited during the penultimate glacial (MIS 6, Rissian), and that underlying older gravel accumulation are predominantly of penultimate interglacial (MIS 7, Riss–Riss interglacial) age. In some areas of the Hochterrassen in the Danube valley south of Regensburg (interglacial Hartinger Schichten, Harting layers), and in some areas of the Rainer Hochterrasse (basal gravel unit I), Hochterrassen gravels are underlain by much older interglacial gravel deposits. These interglacial basal gravel deposits illustrate that the downcutting of these valleys far away from areas of Pleistocene foreland glaciations happened predominantly during warm-temperate interglacial or late-glacial periods. One last interglacial (MIS 5e, Riss–Würm interglacial) Hochterrasse is morphologically preserved in the Isar valley. This Jüngere Moosburger Hochterrasse is composed of the Fagotienschotter (Fagotia gravel, named after the gastropod Fagotia acicularis). The next younger terraces are the Early to Middle Würmian (MIS 5d to MIS 3?) Übergangsterrassen (transitional terraces), whereas the younger one of the two Übergangsterrassen was formed most probably during the Middle Würmian (MIS 3).
