Generation of Gait Events with a FSR Based Cane Handle
Authors: Trujillo-León Andrés , de Guzmán-Manzano Arturo , Velázquez Ramiro , Vidal-Verdú Fernando
Published: August 2021

Gait analysis has many applications, and specifically can improve the control of prosthesis, exoskeletons, or Functional Electrical Stimulation systems. The use of canes is common to complement the assistance in these cases, and the synergy between upper and lower limbs can be exploited to obtain information about the gait. This is interesting especially in the case of unilateral assistance, for instance in the case of one side lower limb exoskeletons. If the cane is instrumented, it can hold sensors that otherwise should be attached to the body of the impaired user. This can ease the use of the assistive system in daily life as well as its acceptance. Moreover, Force Sensing Resistors (FSRs) are common in gait phase detection systems, and force sensors are also common in user intention detection. Therefore, a cane that incorporates FSRs on the handle can take advantage from the direct interface with the human and provide valuable information to implement real-time control. This is done in this paper, and the results confirm that many events are detected from variables derived from the readings of the FSRs that provide rich information about gait. However, a large inter-subject variability points to the need of tailored control systems.
Wave Measurements Using Multi-Frame Processing of Marine Radar Data
Authors: Lyzenga David , Previsic Mirko
Published: August 2021

Marine radars have proven to be useful for measuring ocean waves, but the accuracy of the measurements is limited by several factors including the look-angle dependence of the radar signals as well as noise in the radar data. The look-angle dependence introduces a systematic error or bias in the measurements, and noise causes a random error. This paper describes a method of combining data from multiple radar frames that is optimal in the sense of minimizing the error for a set of biased measurements with random additive noise. The results are shown experimentally to increase the correlation of the radar estimates with buoy measurements.

Published: August 2021

Bridge displacement measurements are important data for assessing the condition of a bridge. Measuring bridge displacement under moving vehicle loads is helpful for rating the load-carrying capacity and evaluating the structural health of a bridge. Displacements are conventionally measured using a linear variable differential transformer (LVDT), which needs stable reference points and thus prohibits the use of this method for measuring displacements for bridges crossing sea channels, large rivers, and highways. This paper proposes a reference-free indirect bridge displacement sensing system using a multichannel sensor board strain and accelerometer with a commercial wireless sensor platform (Xnode). The indirect displacement estimation method is then optimized for measuring the structural displacement. The performance of the developed system was experimentally evaluated on concrete- and steelbox girder bridges. In comparison with the reference LVDT data, the maximum displacement error for the proposed method was 2.17%. The proposed method was successfully applied to the displacement monitoring of a tall bridge (height = 20 m), which was very difficult to monitor using existing systems.
An Improved Feature Selection Method Based on Random Forest Algorithm for Wind Turbine Condition Monitoring
Authors: Li Guo , Wang Chensheng , Zhang Di , Yang Guang
Published: August 2021

Feature selection and dimensionality reduction are important for the performance of wind turbine condition monitoring models using supervisory control and data acquisition (SCADA) data. In this paper, an improved random forest algorithm, namely Feature Simplification Random Forest (FS_RF), is proposed, which is capable of identifying features closely correlated with wind turbine working conditions. The Euclidian distances are employed to distinguish the weight of the same feature among different samples, and its importance is measured by means of the random forest algorithm. The selected features are finally verified by a two-layer gated recurrent unit (GRU) neural network facilitating condition monitoring. The experimental results demonstrate the capacity and effectiveness of the proposed method for wind turbine condition monitoring.
An Approach to Integrating Sentiment Analysis into Recommender Systems
Authors: Dang Cach N. , Moreno-García María N. , Prieta Fernando De la
Published: August 2021

Recommender systems have been applied in a wide range of domains such as e-commerce, media, banking, and utilities. This kind of system provides personalized suggestions based on large amounts of data to increase user satisfaction. These suggestions help client select products, while organizations can increase the consumption of a product. In the case of social data, sentiment analysis can help gain better understanding of a user’s attitudes, opinions and emotions, which is beneficial to integrate in recommender systems for achieving higher recommendation reliability. On the one hand, this information can be used to complement explicit ratings given to products by users. On the other hand, sentiment analysis of items that can be derived from online news services, blogs, social media or even from the recommender systems themselves is seen as capable of providing better recommendations to users. In this study, we present and evaluate a recommendation approach that integrates sentiment analysis into collaborative filtering methods. The recommender system proposal is based on an adaptive architecture, which includes improved techniques for feature extraction and deep learning models based on sentiment analysis. The results of the empirical study performed with two popular datasets show that sentiment–based deep learning models and collaborative filtering methods can significantly improve the recommender system’s performance.
Polymer–Plasticizer Coatings for BTEX Detection Using Quartz Crystal Microbalance
Authors: Iyer Abhijeet , Mitevska Veselinka , Samuelson Jonathan , Campbell Scott , Bhethanabotla Venkat R.
Published: August 2021

Sensing films based on polymer–plasticizer coatings have been developed to detect volatile organic compounds (VOCs) in the atmosphere at low concentrations (ppm) using quartz crystal microbalances (QCMs). Of particular interest in this work are the VOCs benzene, ethylbenzene, and toluene which, along with xylene, are collectively referred to as BTEX. The combinations of four glassy polymers with five plasticizers were studied as prospective sensor films for this application, with PEMA-DINCH (5%) and PEMA-DIOA (5%) demonstrating optimal performance. This work shows how the sensitivity and selectivity of a glassy polymer film for BTEX detection can be altered by adding a precise amount and type of plasticizer. To quantify the film saturation dynamics and model the absorption of BTEX analyte molecules into the bulk of the sensing film, a diffusion study was performed in which the frequency–time curve obtained via QCM was correlated with gas-phase analyte composition and the infinite dilution partition coefficients of each constituent. The model was able to quantify the respective concentrations of each analyte from binary and ternary mixtures based on the difference in response time (τ) values using a single polymer–plasticizer film as opposed to the traditional approach of using a sensor array. This work presents a set of polymer–plasticizer coatings that can be used for detecting and quantifying the BTEX in air, and discusses the selection of an optimum film based on τ, infinite dilution partition coefficients, and stability over a period of time.
A Study of Standardizing Frequencies Using Channel Raster for Underwater Wireless Acoustic Sensor Networks
Authors: Yun Changho , Choi Suhan
Published: August 2021

In this paper, we propose the method to standardize acoustic frequencies for underwater wireless acoustic sensor networks (UWASNs) by applying the channel raster used in the terrestrial mobile communications. The standardization process includes: (1) Setting the available acoustic frequency band where a channel raster is employed via the frequency specification analysis of the state-of-the art underwater acoustic communication modems. (2) Defining the center frequencies and the channel numbers as a function of channel raster, and the upper limit of the value of channel raster. (3) Determining the value of the channel raster suitable for the available acoustic frequency band via simulations. To set the value, three performance metrics are considered: the collision rate, the idle spectrum rate, and the receiver computational complexity. The simulation results show that the collision rate and the idle spectrum rate according to the value of channel raster have a trade-off relationship, but the influence of channel raster on the two performance metrics is insignificant. However, the receiver computational complexity is enhanced remarkably as the value of channel raster increases. Therefore, setting the value of channel raster close to its upper limit is the most adequate in respect of mitigating the occurrence of a collision and enhancing the reception performance. The standardized frequencies based on channel raster can guarantee the frequency compatibility required for the emerging technologies like the Internet of Underwater Things (IoUT) or the underwater cognitive radio, but also improves the network performance by avoiding the arbitrary use of frequencies.
Developing Intercultural Efficiency: The Relationship between Cultural Intelligence and Self-Efficacy
Authors: Wawrosz Petr , Jurásek Miroslav
Published: August 2021

Cultural intelligence measures an individual’s ability to succeed in a culturally unknown environment. Self-efficacy expresses self-confidence in one’s own ability to handle a situation. The two concepts are closely linked, as confirmed by a number of previous studies. Using the multivariate method PLS-SEM, the predictive effect of CQ on self-efficacy is investigated; compared to previous studies, the relationship causality is reversed. A sample of 190 university students was also tested for how this relationship is moderated by two categorical variables: work experience abroad and gender. The results showed that cultural intelligence is a predictor of intercultural self-efficacy in communication. Its impact on the endogenous variable (self-efficacy) is rather weak, but significantly strengthened by work experience abroad. Gender has no effect on this relationship.
Review on Toxic Effects of Di(2-ethylhexyl) Phthalate on Zebrafish Embryos
Authors: Kwan Wing Sum , Roy Vellaisamy A. L. , Yu Kwan Ngok
Published: August 2021

Di(2-ethylhexyl) phthalate (DEHP) is widely used as a plasticizer in consumer products. People are continuously exposed to DEHP through ingestion, inhalation and dermal absorption. From epidemiological studies, DEHP has been shown to associate with various adverse health effects, such as reproductive abnormalities and metabolic diseases. Health concerns have been raised regarding DEHP exposures; therefore, relevant risk assessment has become necessary through toxicological testing of DEHP. In the past 10 years, an increasing number of DEHP toxicity studies have been using zebrafish embryos as an in vivo model due to their high fecundity, rapid embryonic development as well as optical transparency, which have now been established as an alternative of the more conventional rodent model. The aim of the present paper is to review the effects of acute (from embryo stage to ≤1 week) and chronic (from embryo stage to >1 week) DEHP exposures on zebrafish, which start from the embryonic stage, and to analyze acute and potential long-term effects induced by acute exposure and effects induced by chronic exposure of DEHP upon subjecting to exposures, starting from the embryonic stage to different developmental stages, with a view to facilitate risk assessments on DEHP exposures.

Published: August 2021

The ingestion of mycotoxins can cause adverse health effects and represents a severe health risk to humans and livestock. Even though several acute and chronic effects have been described, the effect on the gut metaproteome is scarcely known. For that reason, we used metaproteomics to evaluate the effect of the mycotoxins deoxynivalenol (DON) and zearalenone (ZEN) on the gut microbiome of 15 weaned piglets. Animals were fed for 28 days with feed contaminated with different concentrations of DON (DONlow: 870 μg DON/kg feed, DONhigh: 2493 μg DON/kg feed) or ZEN (ZENlow: 679 μg ZEN/kg feed, ZENhigh: 1623 μg ZEN/kg feed). Animals in the control group received uncontaminated feed. The gut metaproteome composition in the high toxin groups shifted compared to the control and low mycotoxin groups, and it was also more similar among high toxin groups. These changes were accompanied by the increase in peptides belonging to Actinobacteria and a decrease in peptides belonging to Firmicutes. Additionally, DONhigh and ZENhigh increased the abundance of proteins associated with the ribosomes and pentose-phosphate pathways, while decreasing glycolysis and other carbohydrate metabolism pathways. Moreover, DONhigh and ZENhigh increased the abundance of the antioxidant enzyme thioredoxin-dependent peroxiredoxin. In summary, the ingestion of DON and ZEN altered the abundance of different proteins associated with microbial metabolism, genetic processing, and oxidative stress response, triggering a disruption in the gut microbiome structure.

Published: August 2021

Sand flies transmit Leishmania infantum, which is responsible for causing leishmaniasis, as well as many phleboviruses, including the human pathogenic Toscana virus. We screened sand flies collected from a single site between 2017 and 2020 for the presence of both phleboviruses and Leishmania. The sand flies were sampled with attractive carbon dioxide traps and CDC light traps between May and October. We collected more than 50,000 sand flies; 2826 were identified at the species level as Phlebotomus perfiliewi (98%) or Phlebotomus perniciosus (2%). A total of 16,789 sand flies were tested in 355 pools, and phleboviruses were found in 61 pools (6 Toscana virus positive pools, 2 Corfou virus positive pools, 42 Fermo virus positive pools, and 7 Ponticelli virus positive pools, and 4 unidentified phlebovirus positive pools). Leishmania was found in 75 pools and both microorganisms were detected in 16 pools. We isolated nine phleboviruses from another 2960 sand flies (five Ponticelli viruses and for Fermo viruses), not tested for Leishmania; the complete genome of a Fermo virus isolate was sequenced. The simultaneous detection in space and time of the Fermo virus and L. infantum is evidence that supports the co-circulation of both microorganisms in the same location and partial overlap of their cycles. A detailed characterization of the epidemiology of these microorganisms will support measures to limit their transmission.
Papillomaviruses in Domestic Cats
Authors: Munday John S. , Thomson Neroli A.
Published: August 2021

Papillomaviruses (PVs) are well established to cause hyperplastic papillomas (warts) in humans and animals. In addition, due to their ability to alter cell regulation, PVs are also recognized to cause approximately 5% of human cancers and these viruses have been associated with neoplasia in a number of animal species. In contrast to other domestic species, cats have traditionally been thought to less frequently develop disease due to PV infection. However, in the last 15 years, the number of viruses and the different lesions associated with PVs in cats have greatly expanded. In this review, the PV life cycle and the subsequent immune response is briefly discussed along with methods used to investigate a PV etiology of a lesion. The seven PV types that are currently known to infect cats are reviewed. The lesions that have been associated with PV infections in cats are then discussed and the review finishes with a brief discussion on the use of vaccines to prevent PV-induced disease in domestic cats.
Rainstorm Magnitude and Debris Flows in Pyroclastic Deposits Covering Steep Slopes of Karst Reliefs in San Martino Valle Caudina (Campania, Southern Italy)
Authors: Leone Guido , Clemente Pasquale , Esposito Libera , Fiorillo Francesco
Published: August 2021

Debris flows that have occurred in the area of San Martino Valle Caudina (Campania, Southern Italy) are described by geomorphological and hydrological analyses, focusing on the recent event of December 2019. This area can be considered a key example for studying debris-flow phenomena involving the pyroclastic mantle that covers the karstified bedrock along steep slopes. A hydrological analysis of the time series of the maximum annual rainfall, of durations of 1, 3, 6, 12 and 24 h, was carried out based on a new approach to assess rainstorm magnitude. It was quantified by measuring the deviation of the rainfall intensity from the normal conditions, within a specified time period. As the time series of annual maxima are typically skewed, a preliminary transformation is needed to normalize the distribution; to obtain the Z-value of the standard normal distribution, with mean µ = 0 and standard deviation σ = 1, different probability distribution functions were fitted to the actual data. A specific boxplot was used, with box width Z = ±1 and whiskers length Z = ±2. The deviations from these values provide the performance of the distribution fits. For the normalized time series, the rates shown by the trends and relative significance were investigated for the available time series of 11 rain gauges covering the Western–Central Campania region. The most critical condition for the debris-flow initiation appears to occur when a severe or extreme rainfall has a duration ≥ 12 h. The trend analysis did not detect statistically significant increases in the intensity of the rainfall of duration ≥ 6 h.
Soil-Related Predictors for Distribution Modelling of Four European Crayfish Species

Published: August 2021

One of the most critical challenges in species distribution modelling is testing and validating various digitally derived environmental predictors (e.g., remote-sensing variables, topographic variables) by field data. Therefore, here we aimed to explore the value of soil properties in the spatial distribution of four European indigenous crayfish species. A database with 473 presence and absence locations in Romania for Austropotamobius bihariensis, A. torrentium, Astacus astacus and Pontastacus leptodactylus was used in relation to eight digitalised soil properties. Using random forest modelling, we found a preference for dense soils with lower coarse fragments content together with deeper sediment cover and higher clay values for A. astacus and P. leptodactylus. These descriptors trigger the need for cohesive soil river banks as the microenvironment for building their burrows. Conversely, species that can use banks with higher coarse fragments content, the highland species A. bihariensis and A. torrentium, prefer soils with slightly thinner sediment cover and lower density while not influenced by clay/sand content. Of all species, A. astacus was found related with higher erosive soils. The value of these soil-related digital descriptors may reside in the improvement of approaches in crayfish species distribution modelling to gain adequate conservation measures.

Published: August 2021

The EU Water Framework Directive foresees the ecological assessment of surface waters against identified pressures. Nutrient loading is the main pressure impairing the ecological quality of lake ecosystems, and aquatic macrophytes are considered good indicators of ecological response. In this study, we statistically assessed different aspects of aquatic plant (macrophyte) diversity in response to different trophic levels in Mediterranean lakes. We used 5690 relevés of aquatic vegetation, distributed over 305 transects, sampled in 18 freshwater lake ecosystems during 2013–2016. Our results show a significant decrease in taxonomic alpha diversity in lakes with a total phosphorus content above 100 μg/L. Syntaxonomic diversity followed the species richness pattern as well. Functional richness decreased along the trophic gradient, while functional dispersion was higher in lakes with high trophic levels. Taxonomic and functional beta partitioning presented changes in assembly processes leading to greater community homogeneity in lakes with higher trophic levels. In summary, we found no redundancy between taxonomic and functional diversity indices. These results provide novel insights into aquatic plant assembly processes of impacted freshwater lakes needed to forward conservation and restoration practices.
Understanding the Mechanical Biases of Tipping-Bucket Rain Gauges: A Semi-Analytical Calibration Approach
Authors: Segovia-Cardozo Daniel A. , Rodríguez-Sinobas Leonor , Díez-Herrero Andrés , Zubelzu Sergio , Canales-Ide Freddy
Published: August 2021

Tipping bucket rain gauges (TBR) are widely used worldwide because they are simple, cheap, and have low-energy consumption. However, their main disadvantage lies in measurement errors, such as those caused by rainfall intensity (RI) variation, which results in data underestimation, especially during extreme rainfall events. This work aims to understand these types of errors, identifying some of their causes through an analysis of water behavior and its effect on the TBR mechanism when RI increases. The mechanical biases of TBR effects on data were studied using 13 years of data measured at 10 TBRs in a mountain basin, and two semi-analytical approaches based on the TBR mechanism response to RI have been proposed, validated in the laboratory, and contrasted with a simple linear regression dynamic calibration and a static calibration through a root-mean-square error analysis in two different TBR models. Two main sources of underestimation were identified: one due to the cumulative surplus during the tipping movement and the other due to the surplus water contributed by the critical drop. Moreover, a random variation, not related to RI, was also observed, and three regions in the calibration curve were identified. Proposed calibration methods have proved to be an efficient alternative for TBR calibration, reducing data error by more than 50% in contrast with traditional static calibration.
Combined Adsorption and Photocatalytic Degradation for Ciprofloxacin Removal Using Sugarcane Bagasse/N,S-TiO2 Powder Composite

Published: August 2021

N,S-TiO2 deposited on three kinds of pre-treated sugarcane bagasse was synthesized via a sol–gel method. The obtained composites were characterized by various techniques, including scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and photoluminescence spectroscopy (PL). UV-visible induced degradation of ciprofloxacin was investigated. The influence of some experimental parameters such as contact time, pH, dosage, and initial concentration on the efficiency of ciprofloxacin elimination was also evaluated. The highest efficiency was observed for the alkaline pre-treated sugarcane bagasse combined with N,S-TiO2, about 86% under optimal conditions (contact time 150-min irradiation, pH 5.5–6, dosage 0.5 g L−1, and the initial concentration CIP 30 ppm). There may be a rapid ciprofloxacin transition from the adsorption site to the photocatalytic site, and the alkaline pre-treated sugarcane bagasse/N,S-TiO2 prevented the recombining of holes and electrons of the photocatalyst. Furthermore, the alkaline pretreatment sugarcane bagasse/N,S-TiO2 composite material was sustainable, with only a 10% reduction after reusing the material three times. The presence of sugarcane bagasse made the material easy to recover from the liquid phase.

The occurrence of Legionella spp. in the water distribution systems of large hospitals and other healthcare facilities is considered particularly dangerous, due to the critical nature of the hospitalized patients. The aim of this study is to present a pluri-annual environmental surveillance in a large university hospital assessing the prevalence of Legionella spp. and underlining its variability over the years. The samples of water were collected in accordance with the Italian National Guidelines and the sampling sites considered in this study were selected favoring wards with very high-risk patients and with patients at increased risk. The laboratory analyzed a total of 305 water samples deriving from 24 different sampling points. Legionella spp. were detected in 39.4% of samples, the majority of which were contaminated by Legionella pneumophila serogroups 2–14 (68.7%). Statistically significant differences were found among different seasons with a linear trend in positive proportion from summer to spring. Several experimental interventions to prevent and reduce Legionella colonization were attempted, but there is no a definitive method for the complete eradication of this microorganism. The permanent monitoring of hospital water distribution systems is fundamental to preventing the potential risk of nosocomial Legionellosis and to implementing procedures to minimize the risk of Legionella spp. colonization.
Cutaneous manifestations in systemic scleroderma
Authors: Petrishcheva Olga Alekseevna
Published: August 2021

Systemic scleroderma is a chronic disease, the etiology of which is not fully understood. In systemic scleroderma, there is a diffuse change in the skin with the development of fibrosis, as well as with damage to internal organs (in particular, the esophagus, lower gastrointestinal tract, heart, liver and kidneys). The disease can proceed in a generalized and focal form; it is also possible to develop a variant of scleroderma without affecting the skin. A typical clinical picture of the disease is characterized by damage to the skin, the occurrence of multiple joint damage, the development of dysphagia, and the appearance of heartburn, general swelling and the formation of digital contractures. In women, the disease occurs 4 times more often than in men, while it is very rare in children. The onset of the disease is usually observed between the ages of 30 and 50. The diagnosis is established on the basis of the clinical picture, taking into account laboratory data. There is no specific treatment; therapeutic measures are usually aimed at combating complications.
July 25 — the Day of the Dental Technician
Authors: Sakhno Nataliya Nikolaevna
Published: August 2021

Healthy teeth are the key to the normal functioning of the whole organism; people should start taking care of the condition of their teeth from early childhood. It is the teeth that are the only organ of the human body that is incapable of regeneration, so they need special care and the most careful attitude. Not everyone regularly visits dentists, and very few are closely familiar with the work of their right-hand people — dental technicians. At the beginning of the 18th century, serious changes took place in the field of dentistry, i.e. the transition from conservative tooth extraction to the desire for their maximum preservation and restoration. Pierre Fauchard is considered the ideological inspirer of scientific dentistry. By the way, it is dentists who are most directly related to the formation of another scientific discipline — anesthesiology. The first experiments with anesthetics — nitrous oxide (laughing gas) and sulfuric ether — began to be used by dentists as early as the 19th century. It was then that the English naturalist H. Davy experienced the pain-dulling effect of nitrous oxide fumes, and in the 40s of the same century, another dentist had a tooth removed for the first time under the influence of «laughing gas». Many people are used to calling stomatologists dentists, but this broad concept unites not only dentists and surgeons, but also feldshers and technicians. Each individual direction requires a highly qualified specialist, serious practical experience and excellent work skills.

A pediatric radial neck fracture, is still a challenging problem for the treating orthopedic surgeon. We report a pediatric
patient presenting with radial neck fracture and results of open reduction and xation with k wires.
A 8-year-old right-handed boy fell on an out-stretched left arm after being tackled during playing kabaddi and had a radial neck fracture. At the
rst radiologic examination, the anteroposterior and lateral radiographs were showing over 80 degrees of angulation at the radial neck and
subluxation of the radiocapitellar joint. We tried to obtain a closed reduction, but we could not succeed. Then, we performed open reduction while
preserving medial periosteal continuity and vascular supply of the radial head by meticulous surgical dissection. Sixth-month radiography control
and clinical examination conrmed the complete healing of the fracture without any epiphyseal injury. Painless full range of motion without any
restriction of pronation and supination was achieved. The patient and his parents were satised with the outcome. We conclude that, if we can
preserve medial periosteal continuity and vascularity of the radial head with open reduction, satisfactory results are obtainable.

Multi-phase atomic commitment protocols require long-lived resource locks on the participants and introduce blocking behaviour at the coordinator. They are also pessimistic in nature, preventing reads from executing concurrently with writes. Despite their known shortfalls, multi-phase protocols are the mainstay of transactional integration between autonomous, federated systems. This paper presents a novel atomic commitment protocol, STRIDE (Speculative Transactions in Decentralised Environments), that offers strict serializable certification of distributed transactions across autonomous, replicated sites. The protocol follows the principles of optimistic concurrency control, operating on the premise that conflicting transactions are infrequent. When they do occur, conflicting transactions are identified through antidependency testing on the certifier, which may be replicated for performance and availability. The majority of transactions can be certified entirely in memory. Unlike its multi-phase counterparts, STRIDE is nonblocking, decentralised and does not mandate the use of long-lived resource locks on the participants. It also offers a flexible isolation model for read-only transactions, which can be served directly from the participant sites without undergoing certification. Also, update transactions are Φ-serializable, making the certifier immune to the recently disclosed logical timestamp skew anomaly.
Hermenéutica del olvido
Authors: Naishtat Francisco
Published: August 2021

Este artículo parte de un poema manuscrito atribuido póstumamente a Jorge Luis Borges, titulado “Aquí. Hoy” y editado por el crítico colombiano Abad Faciolince. Sin entrar en el problema de la autenticidad de este poema, lo que interesa es su argumento metafísico en conexión con lo que se caracteriza aquí como una “hermenéutica del olvido”, convocando a Paul Ricœur, Friedrich Nietzsche, Jean-Paul Sartre, Martin Heidegger, Walter Benjamin y otros filósofos que inauguraron una reflexión sobre el olvido con raíces fenomenológicas, ontológicas, antropológico-existenciales e históricas. En particular, el autor polariza un pensamiento (in)existencial del olvido a través de la noción de Nachleben con la que Benjamin, en su obra temprana, aborda la temática de la ruina y la espectralidad.
Antymuzyka i antyinstrumenty w tradycji kulturowej Polski
Authors: Przerembski Zbigniew Jerzy
Published: August 2021

W tradycji muzycznej należącej do jej niepisanego nurtu, przekazywanego międzypokoleniowo, w relacji mistrz – uczeń, bez pośrednictwa pisma (zwłaszcza nutowego), oprócz manifestacji dźwiękowych mieszczących się w szeroko pojętym zakresie muzyki, istniało zjawisko określane mianem antymuzyki, rozbrzmiewającej zazwyczaj podczas różnego rodzaju rytuałów przejścia. Antymuzyka zawiera się w szerszym pojęciu wrzawy obrzędowej, rozumianej jako aktywność akustyczna inicjowana w celu apotropaicznym. Stanowi ona odwrotny biegun zjawisk dźwiękowych, które konwencjonalnie przyjęło się uważać za muzykę, stanowiąc wobec niej swego rodzaju opozycję. Antymuzyka związana jest w kulturze tradycyjnej z czasem obrzędowym, będącym odwróceniem czasu „normalnego”, nieobrzędowego.

W kulturze polskiej i europejskiej (ale też innych kontynentów) od wieków utrzymywało się przekonanie, że różnego rodzaju głośne manifestacje akustyczne należą do szerokiego spektrum zabiegów ochronnych przeciwko złym mocom, które, jak wierzono, miały wykazywać wzmożoną aktywność w czasie i miejscach interpretowanych w etnologii i antropologii kulturowej jako graniczne, przejściowe, znamienne zawieszeniem dotychczasowego porządku, powrotem do pierwotnego chaosu i otwarciem kontaktu z zaświatami. Obrzędowa wrzawa mogła też być wzniecana podczas sprawowania różnych zwyczajów i obrzędów cyklu rocznego, m.in. kolędowania, rytuałów zapustnych, śródpościa, wielkopostnych, wielkanocnych, wiosennych, sobótkowych, dożynkowych czy zaduszkowych. W cyklu ludzkiego życia przejściowe były: czas narodzin, inicjacja seksualna, ślub, zgon. Za miejsca przejścia uważano lokalne granice, rozstaje dróg, ale też pustkowia, cmentarze, wzgórza czy duże drzewa.

Wrzawa obrzędowa, antymuzyka może mieć postać wokalną lub instrumentalną, a częściej quasiinstrumentalną, z użyciem narzędzi dźwiękowych czy nawet różnych przypadkowych przedmiotów antyinstrumentów, a także antyinstrumentów, będących parodią czy zaprzeczeniem „normalnych” instrumentów. Należały do nich przede wszystkim diabelskie skrzypce i burczybas.
Piosenka religijna na festiwalu Sacrosong w latach 1969–1978
Authors: Śnieżek Barbara
Published: August 2021

Festiwal Pieśni i Piosenki Religijnej Sacrosong (1969–1999) powstał w czasie, gdy stopniowo wchodziły w życie postanowienia Soboru Watykańskiego II, a wśród nich to dotyczące otwierania Kościoła katolickiego na nowe formy ewangelizacji. Równocześnie olbrzymią popularność w świecie zyskiwała muzyka rockandrollowa. Znalazła ona entuzjastów także wśród muzyków chrześcijańskich, którym rockowe brzmienia posłużyły do przekazywania treści religijnych. Lata 60. XX wieku to również czas, w którym znacząco wzrosło zainteresowanie gatunkiem piosenki, której w twórczości religijnej dały wyraz m.in. utwory francuskiego jezuity Aimé Duvala.

Pomimo trudnej sytuacji społeczno-politycznej PRL, zarówno moda na muzykę młodzieżową jak i na piosenkarstwo religijne bardzo szybko dotarły do grona zainteresowanych. Pierwszą sceną dla repertuaru religijnego w Polsce był festiwal Sacrosong, który w założeniach miał nie tylko sprzyjać powstawaniu i promocji nowych utworów w języku polskim, lecz również angażować w działalność religijną środowisko artystów i młodzież i w ten sposób przeciwdziałać ateizacji społeczeństwa.

W ciągu trzydziestu lat podczas ogólnopolskich Sacrosongów można było usłyszeć zarówno piosenki konkursowe, jak i pieśni, kantaty czy oratoria powstałe na zamówienie organizatorów. Wydarzeniom muzycznym towarzyszyły spektakle teatralne, wystawy, wieczory poezji, konferencje i dyskusje. W jury konkursu zasiadały takie osobistości, jak Wojciech Kilar czy Stefan Kisielewski, muzykę na zamówienie pisali m.in. Jerzy Bauer, Marian Sawa, a teksty – Roman Brandstaetter, Ernest Bryll czy ks. Jan Twardowski.

Artykuł porusza zagadnienia dotyczące historii Sacrosongów, repertuaru oraz społecznej i kulturotwórczej roli tego wydarzenia. Całości dopełniają refleksje związane z samym gatunkiem „głównej bohaterki” festiwalu – piosenki religijnej.

Podemos decir que la contribución de España al desarrollo de las finanzas sostenibles ha sido muy destacada. El fuerte crecimiento de este mercado se ha desencadenado en la segunda parte de la pasada década y España se consolida entre los diez mayores países que toman prestado dinero para proyectos con credenciales positivas para el medioambiente o con fines sociales destinados a colectivos desfavorecidos.
Basados en el Informe Anual publicado por Ofiso en los dos últimos años, trato de identificar algunos de los motivos de esta situación, algunas claves que ayudan a entender las particularidades de nuestro país en este ámbito y los retos que se deberán afrontar en el futuro.
