La necesaria incorporación del farmacéutico comunitario al equipo interdisciplinar que asiste al enfermo en fase terminal
Authors: Ibáñez del Pino Rafael , Saiz Rodríguez Cristina , Rivas Borrell Sonia , López Guzmán José
Published: July 2021

En este trabajo se parte del reconocimiento del importante papel que el farmacéutico comunitario desempeña, en la atención sanitaria, a personas que sufren de un proceso terminal y en sus familiares y/o cuidadores. No hay duda de que es fundamental el consejo, tratamiento y acompañamiento de los profesionales sanitarios en cualquier patología que suponga un compromiso vital. El farmacéutico comunitario, como agente sanitario, debe estar implicado en esos procesos. Sin embargo, en muchas ocasiones es olvidado por un sistema sanitario que desaprovecha, de este modo, a uno de sus profesionales más cualificados.

Estamos convencidos de que el paciente en fase terminal y sus familiares y/o cuidadores se verían muy favorecidos por una implicación mayor de los farmacéuticos en sus procesos. Por esta razón, en este artículo se reflexiona sobre los beneficios que reporta la inclusión del farmacéutico comunitario en el equipo asistencial que atiende a las personas en fase terminal.

La vulnerabilidad humana como un valor ético en el cuidado en final de vida
Authors: Radosta Darío Iván , Ham María del Socorro
Published: July 2021

En este trabajo nos proponemos reflexionar acerca de cómo el carácter ontológicamente vulnerable y frágil de lo humano puede constituirse en un valor ético útil para guiar la práctica de cuidado en el final de la vida. Abordaremos en principio la distinción entre vulnerabilidad contextual y ontológica, para argumentar el carácter inherentemente frágil de la condición humana. Tomaremos la metáfora del sanador-herido como una de las fuentes a partir de las cuales la idea de vulnerabilidad se introduce como modelo de cuidado. Finalmente, expondremos algunas reflexiones acerca de cómo el cuidado en el final de la vida, propio de la filosofía hospice, permite pensar los alcances de la vulnerabilidad humana como un valor ético constitutivo de la práctica de cuidar. Entre las propuestas, creemos que la vulnerabilidad como valor ético justifica, por su carácter relacionalmente construido, el establecimiento de relaciones de ayuda simétricas y la necesidad de reconocer los propios límites.

Published: July 2021

El presente trabajo tiene por objetivo desarrollar y exponer las vicisitudes que atraviesan los pacientes diagnosticados con una enfermedad que amenaza su vida y los pone de cara a la posibilidad de la muerte. Se hará especial mención e hincapié en los aportes que se pueden realizar desde los Cuidados Paliativos, y, especialmente desde nuestra disciplina, la Psicología.

            En primera instancia, comenzamos planteando algunas preguntas e inquietudes que nos surgen como profesionales de la salud mental que darán al debate y la articulación teórica. 

            En segunda instancia, brindamos los aportes que desde la Psicología, ayudan a humanizar la práctica médica al final de la vida: apostar a la subjetividad, a la escucha y a habilitar la palabra al paciente y su familia en el proceso del vivir y del morir.

            En tercera instancia reflejamos y describimos con mayor precisión lo teorizado a partir de la novela de Lev Tolstói “La Muerte de Iván Ilich”, tomando distintos pasajes. Allí este autor, con un discurso novelado, descriptivo y figurado, representa los aconteceres de la persona que es diagnosticada con una enfermedad sin tratamiento curativo.

Authors: Sikorska Iwona , Adamczyk-Banach Magdalena , Polak Mateusz
Published: July 2021

Odporność psychiczna dziecka jest zasobem opartym na czynnikach biologicznych (temperament, stan zdrowia) i społecznych (wpływ wychowawczy i atmosfera w rodzinie). Badania nad radzeniem sobie ze stresem pokazują, że odporna rodzina kształtuje odporne dziecko. Celem badania było poszukiwanie związków pomiędzy odpornością psychiczną rodziców i ich dzieci. Osobami badanymi byli rodzice dzieci w wieku przedszkolnym (N = 129) w wieku 5-6 lat (M = 5,77, SE = 0,44), w tym 121 matek oraz 115 ojców, z ośmiu przedszkoli na terenie Krakowa. Zastosowano dwie metody psychometryczne wypełniane przez rodziców: skalę obserwacyjną DECA (The Devereux Early Childhood Assessment), mierzącą odporność psychiczną dziecka i jej składowe (inicjatywę, samokontrolę i przywiązanie) oraz natężenie dziecięcych zachowań problemowych, a także Skalę Prężności Psychicznej SPP-25 do oceny poziomu odporności psychicznej rodziców. Badanie wykazało silne, pozytywne związki odporności psychicznej rodziców z odpornością psychiczną ich dzieci, tak w ujęciu całościowym, jak i w zakresie jej czynników składowych. Nie zaobserwowano istotnych różnic w profilach odporności pomiędzy dziećmi z wyższym i niższym poziomem zachowań problemowych. Doświadczenie trudnych wydarzeń życiowych wiązało się z niższym poziomem wszystkich aspektów odporności psychicznej zarówno u dzieci, jak i u ich rodziców. Upowszechnianie wiedzy o znaczeniu posiadania i rozwijania zasobów odporności psychicznej rodziców dla zdrowia psychicznego ich dzieci jest ważnym zadaniem społecznym na drodze popularyzacji wiedzy, jak i pedagogizacji rodziców w przedszkolu.

EFEK HEPAPROTEKTIF GULA AREN TERHADAP KARBON TETRAKLORIDA PADA TIKUS
Authors: Suoth Elly Juliana , Herowati Rina , Pamudji Gunawan
Published: July 2021

Abstrak Studi ini meneliti efek gula aren, senyawa bioaktif yang diisolasi dari gula aren, terhadap kerusakan hati akibat karbon tetraklorida (CCl4). Tikus diperlakukan secara intraperitoneal dengan 0,5 ml / kg CCl4 dan kelompok hewan yang berbeda menerima 25, 50, 100, dan 200 mg / kg sudar palem. Pada 24 jam setelah perawatan CCl4, kadar aminotransferase serum dan peroksidasi lipid meningkat secara signifikan, sedangkan kadar glutathione hati menurun. Perubahan ini dilemahkan oleh gula aren. Studi histologis menunjukkan bahwa gula aren menghambat peradangan portal, nekrosis sentrizonal, dan hiperplasia sel Kupffer, yang merupakan tiga karakteristik paling umum dari kerusakan hati yang diinduksi CCl4. Tingkat serum dan mRNA ekspresi tumor necrosis factor-α secara nyata meningkat dengan pengobatan CCl4 tetapi ditekan oleh gula aren. Level mRNA dan ekspresi protein diinduksi nitric oxide synthase dan heme oksigenase-1 meningkat secara signifikan pada 24 jam setelah perawatan CCl4. Gula aren melemahkan peningkatan protein dan ekspresi gen diinduksi nitric oxide synthase tetapi menambah peningkatan heme oxygenase-1. Temuan ini menunjukkan bahwa gula aren melindungi hepatosit dari kerusakan oksidatif yang disebabkan oleh CCl4, dan perlindungan ini kemungkinan disebabkan oleh induksi ekspresi HO-1 dan penghambatan mediator proinflamasi. Abstract This study examined the effects of palm sugar, a bioactive compounds isolated from palm sugar, on carbon tetrachloride (CCl4)-induced liver injury. Mice were treated intraperitoneally with 0.5 ml/kg CCl4 and different groups of animals received 25, 50, 100, and 200 mg/kg palm sudar. At 24 h after the CCl4 treatment, the level of serum aminotransferases and lipid peroxidation was significantly elevated, whereas the hepatic glutathione content was decreased. These changes were attenuated by palm sugar. The histological studies showed that palm sugar inhibited the portal inflammation, centrizonal necrosis, and Kupffer cell hyperplasia, which are the three most common characteristics of CCl4-induced liver damage. The serum level and mRNA expression of tumor necrosis factor-α were markedly increased by the CCl4 treatment but suppressed by palm sugar. The mRNA and protein expression levels of inducible nitric oxide synthase and heme oxygenase-1 increased significantly at 24 h after the CCl4 treatment. Palm sugar attenuated the increase in the protein and gene expression of inducible nitric oxide synthase but augmented the increase in those of heme oxygenase-1. These findings suggest that palm sugar protects hepatocytes from the oxidative damage caused by CCl4, and this protection is likely due to the induction of HO-1 expression and the inhibition of the proinflammatory mediators.

Results: The prevalence of HEV-antibodies was found to be 11.5%. HEV-RNA was not present in any participants. A very high statistical
signicance was seen associated with the risk factors such as educational status, source of drinking water, type of toilet system used, and the habit of
hand washing after using toilets (P<0.01).
Conclusion: Even though the prevalence of HEV among the pregnant women is low, periodic assessment and screening of the pregnant women
should be done. Encouraging the public sector to strictly adhere to the personal hygienic measures will denitely have an impact in the maternal as
well as perinatal mortality and morbidity

Published: July 2021

Introduction: Lip prints and palatal rugae are highly individualistic and stable structure, resist changes to disease and trauma and stays permanent
throughout life. Correlation of lip print, rugae pattern and blood group can contribute to more precise personal identication apart from other
conventional methods.
Aim: To correlate lip prints and rugae pattern to blood group among dental students from Haryana.
Methodology: Total 100 dental students were included in the study and divided into two groups of 50 males and 50 females. Lip prints were
recorded using lipstick and cellophane tape, analyzed according to Suzuki and Tsuchiashi's classication. Rugae pattern were recorded using
alginate and analyzed on the cast according to Kapali et al classication. Blood group of the same individuals were recorded and correlated.
Obtained data was statistically analyzed using SPSS software v 21.0, IBM.
Results: Statistically non-signicant difference was found between both male and female in upper lip pattern (p= 0.751) whereas for lower lip
statistically signicant difference was found in males (p=0.004) with predominance of type III pattern whereas in females type I, II patterns
predominated. For rugae, statistically non-signicant difference was found (p=0.196), in both the groups with predominance of wavy pattern and
no difference in the frequencies of each type of blood group in both genders were seen.
Conclusion: Rugae pattern was found to be signicantly correlated with blood group, with higher frequency of wavy pattern among dental
students from Haryana

Published: July 2021

Generative Adversarial Nets are one of the most popular generative frameworks. In our work, we introduce the SequenceGAN, a method that can generate images based on a given caption by supplying the conditional sequential text input to the generator and the discriminator. Unlike other conditional methods, SequenceGAN uses recurrent layers for better context understanding. We also demonstrated SequenceGANs performance by applying it to the MNIST and Flickr 8k datasets.
Terahertz Meets Untrusted UAV-Relaying: Minimum Secrecy Energy Efficiency Maximization via Trajectory and Communication Co-design
Authors: Tatar Mamaghani Milad , Hong Yi
Published: July 2021

Unmanned aerial vehicles (UAVs) and Terahertz (THz) technology are envisioned to play paramount roles in next-generation wireless communications. In this paper, we present a novel secure UAV-assisted mobile relaying system operating at THz bands for data acquisition from multiple ground user equipments (UEs) towards a destination. We assume that the UAV-mounted relay may act, besides providing relaying services, as a potential eavesdropper called the untrusted UAV-relay (UUR). To safeguard end-to-end communications, we present a secure two-phase transmission strategy with cooperative jamming. Then, we devise an optimization framework in terms of a new measure − secrecy energy efficiency (SEE), defined as the ratio of achievable average secrecy rate to average system power consumption, which enables us to obtain the best possible security level while taking UUR's inherent flight power limitation into account. For the sake of quality of service fairness amongst all the UEs, we aim to maximize the minimum SEE (MSEE) performance via the joint design of key system parameters, including UUR's trajectory and velocity, communication scheduling, and network power allocation. Since the formulated problem is a mixed-integer nonconvex optimization and computationally intractable, we decouple it into four subproblems and propose alternative algorithms to solve it efficiently via greedy/sequential block successive convex approximation and non-linear fractional programming techniques. Numerical results demonstrate significant MSEE performance improvement of our designs compared to other known benchmarks.
Android Printing: Towards On-Demand Android Development Employing Multi-Material 3-D Printer
Authors: Yagi Satoshi
Published: July 2021

In this paper, we propose the concept of Android Printing, which is printing a full android, including skin and mechanical components in a single run using a multi-material 3-D printer. Printing an android all at once both reduces assembly time and enables intricate designs with a high degrees of freedom. To prove this concept, we tested by actual printing an android. First, we printed the skin with multiple annular ridges to test skin deformation. By pulling the skin, we show that the state of deformation of the skin can be adjusted depending on the ridge structure. This result is essential in designing humanlike skin deformations. After that, we designed and fabricated a 3-D printed android head with 31 degrees of freedom. The skin and linkage mechanism were printed together before connecting them to a unit combining several electric motors. To confirm our concept’s feasibility, we created several motions with the android based on human facial movement data. In the future, android printing might enable people to use an android as their own avatar.
Generic modeling, identification and optimal feedforward torque control of induction machines using steady-state machine maps
Authors: Kullick Julian , Hackl Christoph
Published: July 2021

A not yet available look-up table (LUT) based optimal feedforward torque control (OFTC) method for squirrel- cage induction machines (SCIMs) is presented. It is based on: (i) a generic transformer-like machine model in an arbitrarily rotating (d,q)-reference frame, considering nonlinear flux linkages and iron losses in the stator laminations; (ii) machine identification by evaluating steady-state measurements over a grid of (d,q) stator currents, producing frequency-dependent machine maps for e.g. flux linkages, torque, iron resistance and efficiency; and (iii) numerical optimization and extraction of OFTC look- up tables for optimal stator current references depending on reference torque and electrical frequency. In order to increase reproducibility, a feedback temperature controller is employed to keep the stator winding temperature constant. Moreover, throughout the identification, the electrical frequency is kept con- stant (per data set) by adapting the machine speed accordingly using a speed-controlled prime mover; this way the impact of iron losses becomes more balanced than for constant speed operation. The presented measurement results confirm that compared to constant flux operation or scalar V/Hz control, efficiency can be increased particularly in part-load operation by up to 7 %.
Dual-Polarized Wearable Antenna/Rectenna for Full-Duplex and MIMO Simultaneous Wireless Information and Power Transfer (SWIPT)
Authors: Wagih Mahmoud , Hilton Geoffrey S. , Weddell Alex S. , Beeby Steve
Published: July 2021

Owing to the mobility of a wearable antenna and the unpredictable body-centric communications environment, dual-polarization antennas are essential for both communications and energy harvesting. This paper presents a dual-polarized four-port textile antenna/rectenna for wearable simultaneous wireless information and power transfer (SWIPT) applications. The proposed antenna utilizes dual ports for both off-body communication and energy harvesting from horizontal and vertical polarizations. The antenna maintains a 100 MHz bandwidth with an S11 under -10 dB around 2.4 GHz in the presence and absence of the human body, and at least 10~dB small-signal and large-signal isolation between all ports. The antenna maintains a 70-88% measured total efficiency and 8.4--9.6 dBi gain for various on-phantom positions across both communication ports. The measured mutual coupling is under -10 dB between co-polarized rectenna/antenna ports, and under -16~dB between orthogonally-polarized ports. A high RF to DC peak power conversion efficiency of over 70% (+-5%) is achieved with a broadside harvesting pattern. Based on the proposed antenna's performance, SWIPT microstrip antennas can be adopted for both full-duplex and MIMO applications, significantly reducing the complexity of future battery-free networks for both wearable and non-wearable applications.
Hardware Implementation and Performance Analysis of Improved Sphere Decoder in spatially correlated Massive MIMO channels
Authors: Vordonis Dimitris , Paliouras Vassilis
Published: July 2021

Detection for high-dimensional multiple-input multiple-output (MIMO) and Massive MIMO (MMIMO) systems is an active field of research in wireless communications. While most works consider spatially uncorrelated channels, practical MMIMO channels are correlated. This paper investigates the impact of correlation on Sphere Decoder (SD), not only for Single-User (SU) but also for Multi-User (MU) scenarios. The complexity of SD is mainly determined by the Initial Radius (IR) method and the number of visited nodes during detection. This paper proposes both an efficient IR and a new metric constraint in the tree searching algorithm, that significantly decrease the number of visited nodes and render SD feasible for large-scale systems. In addition, a hardware implementation featured with a one-node-per-cycle architecture, minimizes the latency of the detection process. Trade-offs between bit error rate (BER) performance and computational complexity are presented, either modifying the backtracking mechanism or limiting the number of radius updates. Simulation results prove that the proposed optimizations are effective for both correlated and uncorrelated channels, regardless the level of noise. The decoding gain of SD compared to the low-complexity Linear Detectors (LD) is higher in the presence of correlation than in the uncorrelated case. However, as expected, spatial correlation adversely affects the performance and the complexity of SD. Simulation results reported here also confirm that correlation at the side equipped with more antennas is less detrimental. Hardware aspects are examined for both a Virtex-7 FPGA device and a 28-nm ASIC technology.

Published: July 2021

Na discussão do Antropoceno, o ser humano é considerado um dos responsáveis pelas transformações diretas e indiretas ocorridas na paisagem, atuando como agente geológico-geomorfológico. Nesse contexto, complexos minerários possuem grande capacidade de (re)construção das formas do relevo, criando e induzindo feições tecnogênicas. Este artigo aborda as principais transformações no relevo ocorridas com a deposição de aproximadamente 10 milhões de m³ de rejeitos decorrentes do rompimento da barragem I do Complexo Minerário do Córrego do Feijão, inserida na bacia do Ribeirão Ferro-Carvão, em Brumadinho (Minas Gerais, Brasil). Para tanto, realizou-se pela cartografia retrospectiva a comparação entre a morfologia antes e depois do rompimento, através de técnicas de geoprocessamento, fotointerpretação e trabalho de campo. A classificação dos terrenos tecnogênicos possibilitou a identificação dos diferentes processos morfogenéticos relacionados ao Antropoceno, porém, apresentou limitações na distinção das consequências geomorfológicas do desastre, evidenciando a necessidade de aprimoramento das categorias de análise tecnogênica para melhor compreensão de situações similares.

Published: July 2021

The construction industry continues to seek innovative ways to safely, timely and cost-effectively deliver construction projects. Several efforts have been made to automate construction processes but marginial success has been achieved in effectively reducing the long standing risks suffered by the industry. While industry 4.0 promises to improve project efficiency, reduce waste and improve productivity, the transition to this will depend on the successful adoption of many emerging technologies such as virtual design modeling technologies, sensing technologies, data analysis, storage and communication technologies, human-computer interaction technologies, and robotics. To accelerate innovation, digital twins and cyber-physical systems will be a necessity to advance automation and real-time control with these technologies. While digital twin represents a digital replica of the asplanned and as-built facility, cyber physical systems involve integration of physical systems with their digital replica through sensors and actuators. Despite evidence of the efficacy of cyber-physical systems and digital twins for reducing non-fatal injuries, enhancing safety management, improving progress monitoring and enhancing performance monitoring and control of facilities, their adoption in the construction industry is still in its infancy. This paper sheds light on the opportunities offered by cyber-physical systems and digital twins in other industry sectors and advocates for their increased deployment in the construction industry. This paper describes cyber-physical integration of emerging technologies with the physical construction or constructed facility as the next generation digital twin and cyber-physical systems. Potential scenarios of next generation cyber physical system and digital twin for improving workforce productivity, health, and safety, lifecycle management of building systems, and workforce competency are presented.
