Authors: Jiang C. , He X. F. , Yang L. J. , Jiang J. , Wang D. Y. , Yuan Y.
Published: April 2018

Abstract. Relatively total variation (RTV) algorithm, which can effectively decompose structure information and texture in image, is employed in extracting main structures of the image. However, applying the RTV directly to polarimetric SAR (PolSAR) image filtering will not preserve polarimetric information. A new RTV approach based on the complex Wishart distribution is proposed considering the polarimetric properties of PolSAR. The proposed polarization RTV (PolRTV) algorithm can be used for PolSAR image filtering. The L-band Airborne SAR (AIRSAR) San Francisco data is used to demonstrate the effectiveness of the proposed algorithm in speckle suppression, structural information preservation, and polarimetric property preservation.

Published: April 2018

Abstract. In recent decades, urbanization has resulted a massive increase in the amount of infrastructure especially large buildings in large cities worldwide. There has been a noticeable expansion of entire cities both horizontally and vertically. One of the common consequences of urban expansion is the increase of ground loads, which may trigger land subsidence and can be a potential threat of public safety. Monitoring trends of urban expansion and land subsidence using remote sensing technology is needed to ensure safety along with urban planning and development. The Defense Meteorological Satellite Program Operational Line scan System (DMSP/OLS) Night-Time Light (NTL) images have been used to study urbanization at a regional scale, proving the capability of recognizing urban expansion patterns. In the current study, a normalized illuminated urban area dome volume (IUADV) based on inter-calibrated DMSP/OLS NTL images is shown as a practical approach for estimating urban expansion of Beijing at a single period in time and over subsequent years. To estimate the impact of urban expansion on land subsidence, IUADV was correlated with land subsidence rates obtained using the Stanford Method for Persistent Scatterers (StaMPS) approach within the Persistent Scatterers InSAR (PSInSAR) methodology. Moderate correlations are observed between the urban expansion based on the DMSP/OLS NTL images and land subsidence. The correlation coefficients between the urban expansion of each year and land subsidence tends to gradually decrease over time (Coefficient of determination R = 0.80 – 0.64 from year 2005 to year 2010), while the urban expansion of two sequential years exhibit an opposite trend (R = 0.29 – 0.57 from year 2005 to year 2010) except for the two sequential years between 2007 and 2008 (R = 0.14).
HOW WELL DOES SATELLITE FINE MODE AEROSOL PRODUCT VALIDATE WITH GROUND-BASED MEASUREMENTS FOR MODIS AND HIMAWARI-8?
Authors: Jin J. , Yang X. , Liang C. , Zhao W. , Li Z. , Yan X.
Published: April 2018

Abstract. Currently, the validation of MODIS and Himawari-8 aerosol products mostly focuses on AOD, but the validation of their fine mode aerosol data is limited. In this paper, 22 AERONET sites in Asia from 2015 to 2016 were selected to validate the MODIS and the Himawari-8 fine aerosol product. In the validation of all the observation data the accuracy of the MODIS fAOD (RMSE is 0.399 and MAE is 0.280) is higher than the Himawari-8 fAOD (RMSE is 0.433 and MAE is 0.293). For the validation of FMF, the accuracy of MODIS FMF (RMSE is 0.520 and MAE is 0.433) is higher than the Himawari-8 FMF (RMSE is 0.535 and MAE is 0.438) as well. This research also presents the validation in different AERONET locations. From the all validation results, MODIS retrievals of fine mode aerosol products are better than that of Himawari-8’s. However, in comparison with AERONET observations, both MODIS and Himawari-8 retrievals are underestimated. Therefore, we need to further develop the fine mode aerosol retrieval method to obtain more accurate fine mode aerosol product by satellite.

Abstract. How to derive contour of buildings from VHR images is the essential problem for automatic building extraction in urban area. To solve this problem, OSM data is introduced to offer vector contour information of buildings which is hard to get from VHR images. First, we import OSM data into database. The line string data of OSM with tags of building, amenity, office etc. are selected and combined into completed contours; Second, the accuracy of contours of buildings is confirmed by comparing with the real buildings in Google Earth; Third, maximum likelihood classification is conducted with the confirmed building contours, and the result demonstrates that the proposed approach is effective and accurate. The approach offers a new way for automatic interpretation of VHR images.
ATMOSPHERIC PHASE DELAY IN SENTINEL SAR INTERFEROMETRY
Authors: Krishnakumar V. , Monserrat O. , Crosetto M. , Crippa B.
Published: April 2018

Abstract. The repeat-pass Synthetic Aperture Radio Detection and Ranging (RADAR) Interferometry (InSAR) has been a widely used geodetic technique for observing the Earth’s surface, especially for mapping the Earth’s topography and deformations. However, InSAR measurements are prone to atmospheric errors. RADAR waves traverse the Earth’s atmosphere twice and experience a delay due to atmospheric refraction. The two major layers of the atmosphere (troposphere and ionosphere) are mainly responsible for this delay in the propagating RADAR wave. Previous studies have shown that water vapour and clouds present in the troposphere and the Total Electron Content (TEC) of the ionosphere are responsible for the additional path delay in the RADAR wave. The tropospheric refractivity is mainly dependent on pressure, temperature and partial pressure of water vapour. The tropospheric refractivity leads to an increase in the observed range. These induced propagation delays affect the quality of phase measurement and introduce errors in the topography and deformation fields. The effect of this delay was studied on a differential interferogram (DInSAR). To calculate the amount of tropospheric delay occurred, the meteorological data collected from the Spanish Agencia Estatal de Meteorología (AEMET) and MODIS were used. The interferograms generated from Sentinel-1 carrying C-band Synthetic Aperture RADAR Single Look Complex (SLC) images acquired on the study area are used. The study area consists of different types of scatterers exhibiting different coherence. The existing Saastamoinen model was used to perform a quantitative evaluation of the phase changes caused by pressure, temperature and humidity of the troposphere during the study. Unless the phase values due to atmospheric disturbances are not corrected, it is difficult to obtain accurate measurements. Thus, the atmospheric error correction is essential for all practical applications of DInSAR to avoid inaccurate height and deformation measurements.

Published: April 2018

Abstract. Forests provide many goods, Ecosystem services, and resources to humans such as recreation air purification and water protection functions. In rececnt years, there has been an increase in the factors that threaten the health of forests such as global warming due to climate change, environmental pollution, and the increase in interest in forests, and efforts are being made in various countries for forest management. Thus, existing forest ecosystem survey method is a monitoring method of sampling points, and it is difficult to utilize forests for forest management because Korea is surveying only a small part of the forest area occupying 63.7 % of the country (Ministry of Land Infrastructure and Transport Korea, 2016). Therefore, in order to manage large forests, a method of interpolating and spatializing data is needed. In this study, The 1st Korea Forest Health Management biodiversity Shannon;s index data (National Institute of Forests Science, 2015) were used for spatial interpolation. Two widely used methods of interpolation, Kriging method and IDW(Inverse Distance Weighted) method were used to interpolate the biodiversity index. Vegetation indices SAVI, NDVI, LAI and SR were used. As a result, Kriging method was the most accurate method.
EXTRACTION OF BUILT-UP AREAS USING CONVOLUTIONAL NEURAL NETWORKS AND TRANSFER LEARNING FROM SENTINEL-2 SATELLITE IMAGES
Authors: Bramhe V. S. , Ghosh S. K. , Garg P. K.
Published: April 2018

Abstract. With rapid globalization, the extent of built-up areas is continuously increasing. Extraction of features for classifying built-up areas that are more robust and abstract is a leading research topic from past many years. Although, various studies have been carried out where spatial information along with spectral features has been utilized to enhance the accuracy of classification. Still, these feature extraction techniques require a large number of user-specific parameters and generally application specific. On the other hand, recently introduced Deep Learning (DL) techniques requires less number of parameters to represent more abstract aspects of the data without any manual effort. Since, it is difficult to acquire high-resolution datasets for applications that require large scale monitoring of areas. Therefore, in this study Sentinel-2 image has been used for built-up areas extraction. In this work, pre-trained Convolutional Neural Networks (ConvNets) i.e. Inception v3 and VGGNet are employed for transfer learning. Since these networks are trained on generic images of ImageNet dataset which are having very different characteristics from satellite images. Therefore, weights of networks are fine-tuned using data derived from Sentinel-2 images. To compare the accuracies with existing shallow networks, two state of art classifiers i.e. Gaussian Support Vector Machine (SVM) and Back-Propagation Neural Network (BP-NN) are also implemented. Both SVM and BP-NN gives 84.31 % and 82.86 % overall accuracies respectively. Inception-v3 and VGGNet gives 89.43 % of overall accuracy using fine-tuned VGGNet and 92.10 % when using Inception-v3. The results indicate high accuracy of proposed fine-tuned ConvNets on a 4-channel Sentinel-2 dataset for built-up area extraction.

Published: April 2018

Abstract. Leads are only a small part of the polar sea ice structure, but they play a dominant role on the turbulence exchange between the ocean and the atmosphere, they are also important factors about sea ice thickness inversion. Since the early 2000s, Satellite altimetry has been applied to monitor the Arctic sea ice thickness, Satellite altimetry data can be used to distinguish leads and sea ice. In this paper, four parameters including Pulse peakiness (PP), stack standard deviation (SSD), stack kurtosis (SKU) and stack skewness (SSK) are extracted from CryoSat-2 satellite altimetry waveform data. The four parameters are combined into five combinations (PP, PP&SSD, PP&SSD&SKU, PP&SSD&SSK, PP&SSD&SSK&SKU) with constrain conditions to detect the leads. The results of the five methods are compared with MODIS (moderate-resolution imagining spectroradiometer) images and show that, the combination of PP&SSD is better than the single PP, the rest of combinations are the same as the combination of PP&SSD. It turns out, there is no promotion when we add SSK and SKU, successively or simultaneously.

Abstract. In the method of survey underwater topography using remote sensing, and the water surface spectral reflectance R, which remote sensing inversion results were closely related to affects by the water and underwater sediment and other aspects, especially in shallow nearshore coastal waters, different sediment types significantly affected the reflectance changes. Therefore, it was of great significance of improving retrieval accuracy to explore the relation of sediment and water surface spectral reflectance. In this study, in order to explore relationship, we used intertidal sediment sand samples in Sheyang estuary, and in the laboratory measured and calculated the chroma indicators, and the water surface spectral reflectance. We found that water surface spectral reflectance had a high correlation with the chroma indicators; research result stated that the color of the sediment had an very important impact on the water surface spectral, especially in Red-Green chroma a*. Also, the research determined the sensitive spectrum bands of the Red-Green chroma a*, which were 636–617 nm, 716–747 nm and 770–792 nm.
A STATISTICAL TEXTURE FEATURE FOR BUILDING COLLAPSE INFORMATION EXTRACTION OF SAR IMAGE
Authors: Li L. , Yang H. , Chen Q. , Liu X.
Published: April 2018

Abstract. Synthetic Aperture Radar (SAR) has become one of the most important ways to extract post-disaster collapsed building information, due to its extreme versatility and almost all-weather, day-and-night working capability, etc. In view of the fact that the inherent statistical distribution of speckle in SAR images is not used to extract collapsed building information, this paper proposed a novel texture feature of statistical models of SAR images to extract the collapsed buildings. In the proposed feature, the texture parameter of G0 distribution from SAR images is used to reflect the uniformity of the target to extract the collapsed building. This feature not only considers the statistical distribution of SAR images, providing more accurate description of the object texture, but also is applied to extract collapsed building information of single-, dual- or full-polarization SAR data. The RADARSAT-2 data of Yushu earthquake which acquired on April 21, 2010 is used to present and analyze the performance of the proposed method. In addition, the applicability of this feature to SAR data with different polarizations is also analysed, which provides decision support for the data selection of collapsed building information extraction.

Published: April 2018

Abstract. Temporal monitoring of crop types is essential for the sustainable management of agricultural activities on both national and global levels. As a practical and efficient tool, remote sensing is widely used in such applications. In this study, Sentinel-1 Synthetic Aperture Radar (SAR) imagery was utilized to investigate the performance of the sensor backscatter image on crop monitoring. Multi-temporal C-band VV and VH polarized SAR images were acquired simultaneously by in-situ measurements which was conducted at Konya basin, central Anatolia Turkey. During the measurements, plant height of maize plant was collected and relationship between backscatter values and plant height was analysed. The maize growth development was described under Biologische Bundesanstalt, bundessortenamt und CHemische industrie (BBCH). Under BBCH stages, the test site was classified as leaf development, stem elongation, heading and flowering in general. The correlation coefficient values indicated high correlation for both polarimetry during the early stages of the plant, while late stages indicated lower values in both polarimetry. As a last step, multi-temporal coverage of crop fields was analysed to map seasonal land use. To this aim, object based image classification was applied following image segmentation. About 80 % accuracies of land use maps were created in this experiment. As preliminary results, it is concluded that Sentinel-1 data provides beneficial information about plant growth. Dual-polarized Sentinel-1 data has high potential for multi-temporal analyses for agriculture monitoring and reliable mapping.

Published: April 2018

Abstract. In order to improve the efficiency of large scale orthophoto production of city, this paper presents a method for automatic selection of seamlines network in large scale orthophoto based on the buildings’ vector. Firstly, a simple model of the building is built by combining building’s vector, height and DEM, and the imaging area of the building on single DOM is obtained. Then, the initial Voronoi network of the measurement area is automatically generated based on the positions of the bottom of all images. Finally, the final seamlines network is obtained by optimizing all nodes and seamlines in the network automatically based on the imaging areas of the buildings. The experimental results show that the proposed method can not only get around the building seamlines network quickly, but also remain the Voronoi network’ characteristics of projection distortion minimum theory, which can solve the problem of automatic selection of orthophoto seamlines network in image mosaicking effectively.
DAMAGE DETECTION FOR HISTORICAL ARCHITECTURES BASED ON TLS INTENSITY DATA
Authors: Li Q. , Cheng X.
Published: April 2018

Abstract. TLS (Terrestrial Laser Scanner) has long been preferred in the cultural heritage field for 3D documentation of historical sites thanks to its ability to acquire the geometric information without any physical contact. Besides the geometric information, most TLS systems also record the intensity information, which is considered as an important measurement of the spectral property of the scanned surface. Recent studies have shown the potential of using intensity for damage detection. However, the original intensity is affected by scanning geometry such as range and incidence angle and other factors, thus making the results less accurate. Therefore, in this paper, we present a method to detect certain damage areas using the corrected intensity data. Firstly, two data-driven models have been developed to correct the range and incidence angle effect. Then the corrected intensity is used to generate 2D intensity images for classification. After the damage areas being detected, they are re-projected to the 3D point cloud for better visual representation and further investigation. The experiment results indicate the feasibility and validity of the corrected intensity for damage detection.

Published: April 2018

Abstract. DEM beneath forest canopy is difficult to extract with optical stereo pairs, InSAR and Pol-InSAR techniques. Tomographic SAR (TomoSAR) based on different penetration and view angles could reflect vertical structure and ground structure. This paper aims at evaluating the possibility of TomoSAR for underlying DEM extraction. Airborne L-band repeat-pass Pol-InSAR collected in BioSAR 2008 campaign was applied to reconstruct the 3D structure of forest. And sum of kronecker product and algebraic synthesis algorithm were used to extract ground structure, and phase linking algorithm was applied to estimate ground phase. Then Goldstein cut-branch approach was used to unwrap the phases and then estimated underlying DEM. The average difference between the extracted underlying DEM and Lidar DEM is about 3.39 m in our test site. And the result indicates that it is possible for underlying DEM estimation with airborne L-band repeat-pass TomoSAR technique.

Authors: Li X. J. , Yan H. W. , Yang S. W. , Kang L. , Lu X. M.
Published: April 2018

Abstract. The paper proposes a novel pansharpening method based on the pulse-coupled neural network segmentation. In the new method, uniform injection gains of each region are estimated through PCNN segmentation rather than through a simple square window. Since PCNN segmentation agrees with the human visual system, the proposed method shows better spectral consistency. Our experiments, which have been carried out for both suburban and urban datasets, demonstrate that the proposed method outperforms other methods in multispectral pansharpening.

FULLY CONVOLUTIONAL NETWORK BASED SHADOW EXTRACTION FROM GF-2 IMAGERY
Authors: Li Z. , Cai G. , Ren H.
Published: April 2018

Abstract. There are many shadows on the high spatial resolution satellite images, especially in the urban areas. Although shadows on imagery severely affect the information extraction of land cover or land use, they provide auxiliary information for building extraction which is hard to achieve a satisfactory accuracy through image classification itself. This paper focused on the method of building shadow extraction by designing a fully convolutional network and training samples collected from GF-2 satellite imagery in the urban region of Changchun city. By means of spatial filtering and calculation of adjacent relationship along the sunlight direction, the small patches from vegetation or bridges have been eliminated from the preliminary extracted shadows. Finally, the building shadows were separated. The extracted building shadow information from the proposed method in this paper was compared with the results from the traditional object-oriented supervised classification algorihtms. It showed that the deep learning network approach can improve the accuracy to a large extent.
Individual Cyber Security: Empowering Employees to Resist Spear Phishing to Prevent Identity Theft and Ransomware Attacks
Authors: Thomas Jason E.
Published: April 2018

One of the most difficult challenges in information security today is phishing. Phishing is a difficult problem to address because there are many permutations, messages, and value propositions that can be sent to targets. Spear phishing is also associated with social engineering, which can be difficult for even trained or savvy employees to detect. This makes the user the critical point of entry for miscreants seeking to perpetrate cyber crimes such as identity theft and ransomware propagation, which cause billions of dollars in losses each year. Researchers are exploring many avenues to address this problem, including educating users and making them aware of the repercussions of becoming victims of phishing. The purpose of this study was to interview security professionals to gain better insight on preventing users and employees from succumbing to phishing attack. Seven subject-matter experts were interviewed, revealing nine themes describing traits that identify users as vulnerable to attack or strongly resistive to attack, as well as training suggestions to empower users to resist spear phishing attacks. Suggestions are made for practitioners in the field and future research.
An Experimental Study of Clay Swelling Phenomenon by Carbonic Acid Injection in Clay Sandstone: Implication for CO2 Injection
Authors: Riyono Sugeng , Siagian Ucok W.R. , Siregar Hasian P. Septoratno , Permadi Asep K.
Published: April 2018

Significant portion of CO2 is dissolved in reservoir brine during CO2-Enhanced Oil Recovery. Dissolved CO2 forms an acidic environment which could modify rock-fluid interaction. One of the phenomena that could happen due to this interaction is clay swelling which may affect enhanced oil recovery performance. Several experiments were conducted in a number of sandstone core samples, i.e. Imbibition test, Core flood test, Conductivity test, and pH measurement. Imbibition test was conducted to evaluate CO2-saturated brine (approached with carbonic acid) performance toward oil recovery during five days measurement compared with brine imbibition performance. Moreover, core flood experiment was run to determine the effect of dissolved CO2 in brine on injection in sandstone. This is simulated by injecting brine (base case) followed by carbonic acid under 68.3 OC. Thus, conductivity and pH of the imbibed fluids (before & after running imbibition test) were measured to justify occurrence of cation exchange. Interpretation of imbibition test indicated that imbibing carbonic acid, at pH value of about four, resulted in loss of oil recovery about 15% compared with brine due to formation damage caused by clay swelling as sandstone contains clay. The existence of this phenomenon was confirmed by flow resistance at low pH in core sample which was higher than that in brine. This apparent plugging was expected due to severe clay swelling. Meanwhile, the existence of such phenomenon was also clarified with conductivity and pH measurement as there was a great amount of cation exchange.It can be inferred from this study that the rock-fluid interaction from CO2-saturated brine can result in adverse effect, such as injectivity problem and loss of recovery. This finding must be considered in planning CO2 EOR operations, especially when facing condition of watered out oil zone.

Published: April 2018

IoT applications have been evolved in relation to every aspect of human life. The design of the applications adds new challenges such as mobility, scalability, and privacy to the current networking architecture design. For that reason, it is mandatory to investigate new solutions and paradigms such as Information Centric Network (ICN). ICN handles many of the challenges barely handled by current IP networks such as mobility and scalability, by using in-network caching and content retrieving based on contents names instead of host addresses. This paper presents a privacy-aware ICN architecture for IoT environments based on the Model-View-Controller (MVC) publish/Subscribe communication approach. This architecture focuses on supporting mobility, scalability, and privacy. A communication and processing cost comparison between Publish/Subscribe N-Tier and Publish/Subscribe MVC architectures, shows that the later outperforms N-Tier in communication, processing cost, and parallelism capabilities. Reasoning and planning for publishing actuation commands scenarios is performed using Situation Calculus which is used to formalize the communications in causality and temporal framework.

In this work the anthropogenic sediments from area of Old Town Szczecin
(Square of Orła Białego) were characterized. It was found that layer
of these sediments had thickness of approx. 4 m and materials contained
therein were enriched in organic matter, including humus. These sediments
contained a huge amount of mechanical deposits which were dominated by
building rubble that formed of 3-meter continuous rubble layer within the
anthropogenic layer. Building rubble enriched materials in calcium carbonate
and caused their alkalinisation even to level pHKCl=8.7. These deposits
caused also a very clear increase of lead and zinc contents, clear increase of copper content and slightly enrichment of materials in cadmium.
Not confirmed the effect of mechanical deposits on nickel content.
The maximum content of Zn, Cu, Pb and Cd were respectively: 685, 146,
716 and 1.7 mg·kg-1
. These amounts were higher than acceptable level for

The paper attempts to develop a new way of verifying and updating data
collected in Land and Property Databases, containing information on land
and buildings. The report examines currently existing law regulating for
the collection of registration of data, mainly in their geometrical aspect,
proposes possible ways of validating these data and enriches with some
new elements based on UAS technology. By supplementing the databases
with new Land and Property objects the study was prepared, taking into
account some new legislative provisions related to the principles and scope
of the collected data in the Land and Property's resources. The basic problem
with the use of photogrammetry from the UAV level for measuring the
location and shape of considered objects is ensuring the proper accuracy.
The compliance of accuracy condition and the visibility of the objects
makes it possible to significantly supplement the registration data databases
with some new elements such as terraces, verandas, stairs, etc. The
paper discusses these issues and presents the results performed on real objects,
together with their accuracy rating. It has been found that images
made from low altitude can be used to measure new object classes, update
land and buildings database, and also, to a limited extent, validate Land
and Property Databases for another, from the up-visible objects.

The INSPIRE Directive went into force in May 2007 and it resulted in
changing the way of thinking about spatial data in local government.
Transposition of the Directive on Polish legislation is the Law on spatial
information infrastructure from 4 March 2010., which indicates the need
for computerization of spatial data sets (including land-use planning).
This act resulted in an intensification of thinking about the computerization
of spatial data, but, according to the authors, the needs and aspirations of
the digital land-use planning crystallized already before the INSPIRE Directive
and were the result of technological development and increasing
the awareness of users.
The authors analyze the current state of land-use planning data computerization
in local governments. The analysis was conducted on a group of
more than 1,700 local governments, which are users of spatial data management
(GIS) technology eGmina.

The article deals with the issue of architecture as a form of knowledge transition
of cultural continuity of a certain area basing on the example of a
project: "Agrotourismo with equestrian center in Drzonków.” The study
was devoted to the design of agro-touristic hub with an equestrian center
for 14 horses, at the site of a former equestrian complex, in a place which
has recently become a part of Zielona Góra.
The concept posits complementing functional gaps in the area, by creating
a recreation resort offering riding lessons, cooperating with the Regional

Published: April 2018

The aim of conducted studies was to identify atypical diseases symptoms occurring in agricultural crops located in the area affected by industry (agricultural area covered by gas and dust emissions from Copper Smelter GŁOGÓW), as well as in crops grown on areas not influenced by antropopression (Lasocice near Leszno, Uścikowo near Oborniki Wlkp., Barcinek near Biskupice Wlkp.). Efforts have been made to determine whether changes observed in plants are a result of non-infectious diseases. Occurrence of such diseases may be the outcome of direct anthropogenic factors impact on the plants, or the result of deficiency or excess of nutrients contained in soils. The research helped to determine the role of abiotic factors causing these diseases in controlled crops.
It is time for rural training in family medicine in Brazil!
Authors: Almeida Magda Moura , Floss Mayara , Targa Leonardo Vieira , Wynn-Jones John , Chater Alan Bruce
Published: April 2018

The gap between health needs and the training of human resources for health is much more evident in rural areas. In Brazil, a country of continental dimensions, these differences become more challenging. The diversity of geographical and administrative barriers to access makes the health indicators of rural and remote populations worse than those of the urban population. Family Medicine could address the social determinants of health through the provision of human services and play an important role in low-income rural residents’ health status. This essay is an urgent call for the debate on models for projecting heath workforce supply and requirements for rural areas in Brazil.

Authors: Abu Hawa Ozien , Aboumatar Hanan , Carson Kathryn , Goldberg Robert , Cooper Lisa
Published: April 2018

Objective: To assess patients’ knowledge about hypertension and its association with heart healthy lifestyle practices and medication adherence.Methods: We conducted a cross sectional survey of 385 adults with hypertension treated at 2 primary care clinics in Baltimore, Maryland, USA. We used an 11-item measure to assess hypertension knowledge and obtained self-reports on dietary changes, engagement in aerobic exercise and medication adherence. Results: Approximately 85% of patients properly identified high blood pressure, but more than two-thirds were unaware that hypertension lasts a lifetime once diagnosed; one-third were unaware that hypertension could lead to renal disease. Patients with low hypertension knowledge were less likely to reduce their salt intake (OR=0.44 [95% CI: 0.24-0.72]) and eat less to lose weight (OR=0.48 [95% CI: 0.26-0.87]) than patients with high hypertension knowledge.Conclusion: In general, patients were knowledgeable about hypertension, but most were unaware that hypertension is a lifelong condition and could lead to kidney disease. High knowledge of hypertension was associated with healthy lifestyle practices including eating less to lose weight and dietary salt reduction.Practice Implications: Intensifying education strategies to improve patients’ knowledge of hypertension may enhance their engagement in heart healthy lifestyle practices for optimal blood pressure control.
Fédéralisme et négociations commerciales au Canada : l’Alé, l’aecg et le ptp comparés
Authors: Paquin Stéphane
Published: April 2018

Selon la Constitution et la jurisprudence canadienne, le gouvernement fédéral possède les pleins pouvoirs en ce qui concerne la conclusion de traités et la responsabilité du commerce international. Malgré cette situation, les provinces jouent un rôle de plus en plus important dans les négociations commerciales. Cette situation s’explique par le fait que ces négociations touchent de plus en plus aux champs de compétence des provinces et que le gouvernement fédéral ne peut imposer ses traités aux provinces. Dans cet article, nous comparons la participation des provinces à trois négociations d’importance : l’Aléavec les États-Unis, l’aecgentre le Canada et l’Union européenne et le Partenariat transpacifique.
Les grands défis du Mexique face au Partenariat transpacifique
Authors: Foucras Nicolas Pierre
Published: April 2018

Le Mexique a lié son destin à ceux de ses voisins nord-américains par la signature de l’Accord de libre-échange nord-américain (Aléna). Cependant, avec la forte croissance économique qu’enregistre la région pacifique de l’Asie, le Mexique se cherche un nouvel élan. C’est par son insertion dans les dynamiques commerciales actuelles, notamment par la promotion et la participation à des négociations comme celles de l’Alliance du Pacifique (ptp) entre pays latino-américains, mais plus particulièrement par sa participation à la construction du Partenariat transpacifique (ptp), signé le 4 février 2016, que le Mexique cherche à préserver sa position comme plateforme incontournable du commerce et des investissements internationaux associés aux chaînes de valeur des États-Unis. Cet article propose une analyse des motifs qui ont poussé le Mexique à intégrer le ptp ainsi que des opportunités et des défis qui en découlent.
Le Partenariat transpacifique et le futur du commerce bilatéral Brésil-Chine
Authors: Moreira Carlos Américo Leite , Sebag de Magalhães Emanuel
Published: April 2018

Le profil du commerce bilatéral entre le Brésil et la Chine ces dernières années a joué un rôle crucial dans le mouvement de primarisation des exportations brésiliennes. On constate une concentration des ventes internationales brésiliennes vers ce pays dans certains produits de base. La bonne performance des exportations du Brésil vers la Chine reflète le dynamisme des produits dans lesquels le Brésil est compétitif à l’échelle mondiale. Autrement dit, il ne s’agit pas d’une stratégie active de diversification et de création de nouveaux marchés. Les exportations brésiliennes profitent de la croissance des importations chinoises de produits de base. Dans quelle mesure le Partenariat transpacifique (ptp) pourra-t-il affecter la dynamique commerciale entre ces deux pays ? Cet accord mettra-t-il en cause le modèle intersectoriel de commerce entre les deux pays ? La Chine exporte davantage de produits manufacturés et elle importe surtout des matières premières.
Empatia e dor: interlocuções entre Edith Stein e Merleau-Ponty
Authors: Caminha Iraquitan de Oliveira
Published: April 2018

O objetivo desse artigo é discutir a empatia do ponto de vista da perspectiva fenomenológica de Stein. Com base nessa leitura sobre a empatia, iremos correlacionar as concepções de corpo próprio de Stein e Merleau-Ponty, visando mostrar como a empatia pode ser compreendida como experiência intercorpórea. Depois de mostrar a empatia enquanto experiência intercorpórea, iremos considerar o problema de sentir a dor do outro no contexto da clínica psicanalítica. Finalmente, propomos pensar um quadro de fibromialgia para discutir o encontro com a dor do outro pela escuta flutuante do corpo do outro como obra de arte.
Silêncio e interioridade pessoal em Edith Stein
Authors: Mahfoud Miguel
Published: April 2018

Analisando o texto “O castelo interior” de Edith Stein, aponta-se a experiência de silêncio relacionada com cada um dos sete níveis de interioridade pessoal identificados na imagem do castelo. Comentando em termos de antropologia filosófica o texto sobre experiência mística de Teresa D’Ávila, Stein abre caminho para a identificação de diversas modalidades de silêncio: silêncio baseado na dispersão da pessoa na vivência das circunstâncias externas, silêncio ligado à experiência de si nas vivências das circunstâncias, silêncio associado a respostas a apelos identificados na própria experiência, silêncio vivido na busca da própria interioridade pessoal, silêncio diante do acontecimento da própria pessoa e do mundo com seu mistério, silêncio nas experiências de lucidez, silêncio definitivo e silêncio na vivência do núcleo da pessoa. As diversas modalidades de silêncio são apresentadas na sua conexão com cada grau da estrutura graduada do ente. Apontam-se implicações para uma ciência da experiência propriamente humana.
Justiça e Direitos Humanos na Filosofia do Direito de Emmanuel Lévinas
Authors: Renan Hamel Marcio
Published: April 2018

A presente pesquisa apresenta uma reconstrução hermenêutica do conceito de justiça presente na filosofia de Emmanuel Lévinas, tal como aparece em alguns de seus escritos. Para cumprir a tarefa anunciada, analisa-se inicialmente a relação entre responsabilidade e justiça, considerando o reconhecimento do outro pela consciência moral, aparecendo, então a justiça. Em segundo lugar, investiga-se o entendimento levinasiano acerca dos direitos humanos, considerando a ideia de direitos do outro homem, em clara inversão à concepção tradicional desses direitos. Finalmente, o estudo valoriza a contribuição de Emmanuel Lévinas à filosofia do direito contemporânea, no sentido da necessidade de uma reconstrução epistêmica da teoria da justiça e dos direitos do homem.
O idealismo transcendental segundo Schopenhauer: de Berkeley para além de Kant
Authors: Moraes Dax
Published: April 2018

Sabe-se que Schopenhauer louva Berkeley como um grande idealista ao lado de Kant, seu principal inspirador. Schopenhauer, por sua vez, não segue o caminho kantiano, antes elaborando uma dura crítica da Analítica Transcendental e reformulando profundamente a doutrina do conhecimento intuitivo. De Berkeley, Schopenhauer toma a tese de que “ser é ser percebido”, que, em suas palavras, corresponde à sentença “o mundo é minha representação”. Apesar disso, são poucas as vezes em que Berkeley é mencionado por Schopenhauer ainda que se trate de importantes ocasiões. Isso talvez possa servir como explicação para o estranho fato de ser tão raro encontrar o nome de Berkeley nos estudos sobre a metafísica ou a teoria do conhecimento de Schopenhauer, exceto como casuais alusões àquelas breves menções. Diante disso, o presente artigo consiste em uma introdução à seguinte tese: o idealismo transcendental de Schopenhauer desenvolve o pensamento berkeleyano, utilizando-se do ponto de vista kantiano, de maneira a levar este último à consequência que Kant teria querido evitar.
