The cultural landscape of Campina de Faro: solutions based on water heritage and cultural tourism

The European INCULTUM project has at its core ten pilot cases with the aim of exploring the potential of peripheral and neglected territories when managed by local communities and stakeholders, within the framework of community-based cultural tourism. This article focuses on the Portuguese pilot, located in the Algarve region in southern Portugal, and describes the process of research and cooperation carried out in the first two years of the project to fulfil that goal. The cultural landscape of the Campina de Faro is characterized by the presence of vegetable gardens and orchards associated with a historical, evolving, and adaptable irrigation system, revealing a technological unit (hydraulic infrastructures) and a social unit (local community). For this irrigation system (in abandonment and disuse) to survive, its study and rehabilitation is essential, as well as the dissemination of its importance and added value for society and the environment. In both cases, the role of residents is crucial as they hold ancient knowledge and know-how and it is on them that the improved management of natural (water, soil) and cultural (food goods, heritage) resources depends. It is in the perspective of the importance of the farmers and local producers as the main actor and decision-maker in the planning, development, and management of resources to serve the objectives of both horticultural production and the enjoyment of the agrarian landscape, that the key role of the hydraulic heritage and the active participation of local communities as a basis for the development of sustainable tourism is recognised.

Assessing personal protective equipment compliance in a polish healthcare setting during the COVID-19 pandemic – A pilot case study

Objective: The purpose of this study is to identify failures in proper Personal Protective Equipment (PPE) usage in a healthcare hospital environment to enhance PPE compliance through proper donning and doffing procedures.Methods: We used naturalistic observation (shadowing) of PPE donning and doffing by healthcare medical staff in their hospital work setting to identify non-conformities to compliant donning and doffing of PPE.Results: We found an average of 1.84 non-conformances per healthcare worker across the donning procedures and 2.06 non-conformances in the doffing procedures per healthcare provider. Nurses experienced 1.94 average non-conformances in the donning procedures, while physicians average 1.75 non-conformances. Nurses experienced 2.29 average doffing nonconformances, while physicians averaged 1.85 average doffing non-conformances during the study. PPE compliance is critical to protect both healthcare workers and patients in the healthcare setting, as well as building a culture of safety.Research implications: Appropriate training and compliance should be performed to ensure appropriate PPE donning and doffing protocols are adhered to, so that it reduces the transmission of disease and infections. Future studies will explore the environmental, cultural and operational factors that contribute to PPE compliance in healthcare.Conclusions: This is the first study to quantify donning and doffing errors of personal protective compliance within the realm of environmental and cultural impacts.

CROP WATER CONSUMPTION MODELLING AT OUTLET LEVEL BY USING REMOTE SENSING AND GIS

The enlarged demand of water due to agriculture expansion, increasing industrial and domestic needs, compounded with climate change is causing scarcity of water globally and Pakistan is also facing same conditions. Due to limited availability of water, it is necessary to adopt global best practices being employed for sustainable agricultural water management. Remote sensing techniques are being intensively used around the globe with confidence to monitor the crops growth and crop water use. The aim of the research is to develop crop water consumption monitoring system at the outlet level to regulate irrigation water distribution at farm level. Surface Energy Balance Algorithm for Land (SEBAL) is used to develop pilot case study for year 2017-18 at a distributary canal command level named 5R-Yousafwala located in Sahiwal District. Crop classification based on Landsat-8 imagery was provided by Punjab Irrigation Department. Landsat-8 and Sentinel-2 images were acquired for NDVI monitoring. Metrological data for Penman Monteith based evapotranspiration calculation was acquired from Global Land Data Assimilation System (GLDAS). Analogue cadastral maps of outlet command areas were converted to digital georeferenced format. The provided crop classification was verified after discussion with farmers during detailed field survey. In Rabi season of 2017-18, mean evapotranspiration (ET) actual was estimated about 352 mm, while in Kharif season of 2018, it was estimated as 425 mm. The crop water deficit was estimated as 36 % in rabi season and 30 % in kharif season. Irrigation share was only 37 % in Rabi season and 48% in Kharif season. Rainfall contributed 09 % in Rabi season and 30% in Kharif season. Groundwater was paramount contributor with 54 % share in rabi season while in Kharif season it contributed relatively minor share of 22%. The ET potential and ET actual fluctuate in all outlet commands due to the diverse crop cover and economic capacity to pump groundwater. The results could be proved very useful for irrigation department to monitor and reform the irrigation supplies at particular outlets by observing the crop demand, weather conditions and crop stage instead of monitoring outlet discharge only.

A pilot case series for concurrent validation of inertial measurement units to motion capture in individuals who use unilateral lower-limb prostheses.

Inertial measurement units (IMUs) may be viable options to collect gait data in clinics. This study compared IMU to motion capture data in individuals who use unilateral lower-limb prostheses. Participants walked with lower-body IMUs and reflective markers in a motion analysis space. Sagittal plane hip, knee, and ankle waveforms were extracted for the entire gait cycle. Discrete points of peak flexion, peak extension, and range of motion were extracted from the waveforms. Stance times were also extracted to assess the IMU software's accuracy at detecting gait events. IMU and motion capture-derived data were compared using absolute differences and root mean square error (RMSE). Five individuals (n = 3 transtibial; n = 2 transfemoral) participated. IMU prosthetic limb data was similar to motion capture (RMSE: waveform ≤4.65°; discrete point ≤9.04°; stance ≤0.03s). However, one transfemoral participant had larger differences at the microprocessor knee joint (RMSE: waveform ≤15.64°; discrete ≤29.21°) from IMU magnetometer interference. Intact limbs tended to have minimal differences between IMU and motion capture data (RMSE: waveform ≤6.33°; discrete ≤9.87°; stance ≤0.04s). Findings from this pilot study suggest IMUs have the potential to collect data similar to motion capture systems in sagittal plane kinematics and stance time.

Sodium glucose co-transporter-2 inhibitors in intensive care unit patients with type 2 diabetes: a pilot case control study

BackgroundSodium glucose co-transporter-2 (SGLT2) inhibitors improve long-term cardiovascular and renal outcomes in individuals with type 2 diabetes. However, the safety of SGLT2 inhibitors in ICU patients with type 2 diabetes is uncertain. We aimed to perform a pilot study to assess the relationship between empagliflozin therapy and biochemical, and clinical outcomes in such patients.MethodsWe included 18 ICU patients with type 2 diabetes receiving empagliflozin (10 mg daily) and insulin to target glucose range of 10–14 mmol/l according to our liberal glucose control protocol for patients with diabetes (treatment group). Treatment group patients were matched on age, glycated hemoglobin A1c, and ICU duration with 72 ICU patients with type 2 diabetes exposed to the same target glucose range but who did not receive empagliflozin (control group). We compared changes in electrolyte and acid–base parameters, hypoglycemia, ketoacidosis, worsening kidney function, urine culture findings, and hospital mortality between the groups.ResultsMedian (IQR) maximum increase in sodium and chloride levels were 3 (1–10) mmol/l and 3 (2–8) mmol/l in the control group and 9 (3–12) mmol/l and 8 (3–10) mmol/l in the treatment group (P = 0.045 for sodium, P = 0.059 for chloride). We observed no differences in strong ion difference, pH or base excess. Overall, 6% developed hypoglycemia in each group. No patient in the treatment group and one patient in the control group developed ketoacidosis. Worsening kidney function occurred in 18% and 29% of treatment and control group patients, respectively (P = 0.54). Urine cultures were positive in 22% of treatment group patients and 13% of control group patients (P = 0.28). Overall, 17% of treatment group patients and 19% of control group patients died in hospital (P = 0.79).ConclusionsIn our pilot study of ICU patients with type 2 diabetes, empagliflozin therapy was associated with increases in sodium and chloride levels but was not significantly associated with acid–base changes, hypoglycemia, ketoacidosis, worsening kidney function, bacteriuria, or mortality.

Remote arts therapy in collaborative virtual environment: A pilot case study

Motivated by the unique experience of creating three-dimensional artworks in virtual reality (VR) and the need for teletherapy due to the global pandemic, we conducted this pilot case study to explore the feasibility and effectiveness of using a custom-designed collaborative virtual environment (CVE) to enable remote arts therapy. Three participants (two females and one male) experiencing moderate to high stress as measured by the Perceived Stress Scale (PSS) joined this study. Each participant had eight 45-minute one-on-one sessions with the therapist for eight consecutive weeks. These eight sessions covered eight art creation themes and were delivered following pre-designed protocols. The CVE was the only medium to facilitate the sessions, during which the therapist and the participants were physically separated into two rooms. The quantitative and qualitative results suggested that the CVE-enabled approach was generally feasible and was welcomed by both the participants and the therapist. However, more evidence of the approach’s effectiveness in enhancing the participants’ mental wellbeing is needed because the results of the pilot case study were affected by the pandemic. The advantages and disadvantages of this approach and the CVE were investigated from practicality and technological affordance perspectives. Potential improvements to the CVE are also proposed to better facilitate the practice of remote arts therapy in CVE. We encourage future studies to cautiously investigate CVE-enabled remote arts therapy in clinical settings and collect more evidence regarding its effectiveness in addressing clinically diagnosed mental disorders and other complications.

Omnichannel Retailing

This paper aims to examine the factors affecting the postadoption of RFID technology as part of omnichannel strategies in the retail industry. In addition, it evaluates how this innovation contributed to the improvement of the quality of corporate financial information. We employed an exploratory multiple-case study design based on qualitative research, by using semi-structured interviews, and public financial and sustainability reports as sources of evidence. The data collection and analysis were performed in 2022 for the pilot case of a manufacturer and the formal cases of three retailers. The results reveal that RFID postadoption is influenced by technological factors (relative advantage, observability, trialability, and perceived costs), organizational factors (top management support and firm size), and environmental factors (competitive pressure and external support). Surprisingly, loss recognition and loss provision are the most affected accounting practices, differently from what has been suggested by the accounting literature. We also found that item-level RFID enables increased frequencies of full inventory counts, providing inventory accuracy of records and real-time inventory visibility. This results in the improvement of accounting information quality in terms of relevance, faithful representation, timeliness, comparability, understandability, verifiability, and value-added. Our findings may contribute to both research and practice, as well as IS and accounting fields. We identified and investigated the phenomenon of the recent movement of RFID adoption by large retail companies listed in B3 during the COVID-19 pandemic in Brazil. Finally, we provide a theoretical model based on the TOE framework integrated to a construct of accounting information quality specifically developed for the RFID postadoption context.

Preoperative n-BCA embolization in the resection of submandibular lymphatic malformations refractory to sclerotherapy treatment: A pilot case series.

Lymphatic malformations in the submandibular neck pose unique challenges to treatment that elevate their risk of recurrence. This case series provides a review of five patients, previously treated with sclerotherapy or with a history of multiple infections, who were treated in a novel fashion: single-stage resection using preoperative n-butyl cyanoacrylate (n-BCA) glue embolization. We performed a retrospective medical record review of five patients who underwent single-stage n-BCA embolization by Interventional Radiology followed by surgical resection by Otolaryngology, including a review of their symptoms, previous treatments, and post-treatment surveillance, with follow-up ranging from 4 to 24 months after the treatment of interest. All study subjects had unremarkable perioperative courses, and four patients did not demonstrate any evidence of disease recurrence or persistence during the follow-up period. One patient was found to have a small area of persistent disease on post-treatment imaging, but has remained symptom free. Treatment of submandibular lymphatic malformations with n-BCA embolization followed by surgical resection can be performed in a single stage. This case series demonstrates that this approach can yield durable relief of symptoms, even in patients whose lesions were refractory to previous treatments.

Evaluation of muscle strength and quality in North African patients with chronic hepatitis B: A pilot case control study

ABSTRACT Early detection of alteration of muscle strength, quantity, and quality, and sarcopenia is useful in non-cirrhotic chronic hepatitis B (NC-CHB) patients. Studies, which explored the handgrip strength (HGS) are scarce with questionable results, and no previous case-control study explored the presence of sarcopenia. The aim of this study was to assess the muscle strength [i.e.; HGS absolute (HGSA), HGSA/body mass index (BMI)], muscle quantity [i.e.; appendicular skeletal muscle (ASM), ASM/height2, ASM/total body weight (TBW), ASM/BMI], and muscle quality [i.e.; HGSA/total muscle mass (TMM), HGSA/ASM] of NC-CHB patients. This was a case-control study. Cases (n = 26) were untreated NC-CHB patients, and controls (n = 28) were ‘apparently’ healthy participants. Muscle mass was estimated via the TMM (kg) and ASM (kg). Muscle strength was evaluated via the HGS data [i.e.; HGSA (kg), HGSA/BMI (m2)]. Six variants of HGSA were determined: highest values for the dominant and non-dominant hands, highest value between the two hands, averages of the three measurements for the two hands, and the average of the highest values of the two hands. Muscle quantity was expressed in three relative variants (ASM/height2, ASM/TBW, and ASM/BMI). Muscle quality was evaluated via relative HGS data adjusted by muscle mass (i.e.; HGSA/TMM, HGSA/ASM). Probable and confirmed sarcopenia were retained in front of low muscle strength, and low muscle strength and muscle quantity or quality, respectively. There were no significant differences between controls and NC-CHB patients in values of muscle i) Strength whatever the HGS’ mode of expression (e.g.; HGSA/BMI: 1.59 ± 0.54 vs. 1.53 ± 0.54 m2, p = 0.622, respectively), ii) Quantity (e.g.; ASM/BMI: 0.79 ± 0.24 vs. 0.77 ± 0.23 m2, p = 0.883), and iii) Quality (e.g.; HGSA/ASM: 2.00 ± 0.25 vs. 2.01 ± 0.41, p = 0.952, respectively). One NC-CHB participant had a confirmed sarcopenia. To conclude, both controls and NC-CHB patients had similar HGS values. Only one NC-CHB patient had a confirmed sarcopenia.

Chest Examination with Wireless Technology in a Patient with Fibrotic Disease: A Pilot Case Report

Physicians use auscultation as a standard method of thoracic examination: it is simple, reliable, non-invasive, and widely accepted. Artificial intelligence (AI) is the new frontier of thoracic examination as it makes it possible to integrate all available data (clinical, instrumental, laboratory, functional), allowing for objective assessments, precise diagnoses, and even the phenotypical characterization of lung diseases. Increasing the sensitivity and specificity of examinations helps provide tailored diagnostic and therapeutic indications, which also take into account the patient's clinical history and comorbidities.
 Several clinical studies, mainly conducted in children, have shown a good concordance between traditional and AI-assisted auscultation in detecting fibrotic diseases. On the other hand, the use of AI for the diagnosis of obstructive pulmonary disease is still debated as it gave inconsistent results when detecting certain types of lung noises, such as wet and dry crackles. Therefore, the application of AI in clinical practice needs further investigation.
 In the case we present, data integration allowed us to make the right diagnosis, avoid invasive procedures, and reduce the costs for the national health system; we show that integrating technologies can improve the diagnosis of restrictive lung disease. Randomized controlled trials will be needed to confirm the conclusions of this preliminary work.

Serum YKL-40 as a Potential Biomarker for Sepsis in Term Neonates-A Pilot Study.

Although YKL-40 is a promising diagnostic biomarker of sepsis in adults, its value in neonatal sepsis is not known. The study objectives included assessing the levels and diagnostic value of serum YKL-40 in term neonates with sepsis and comparing YKL-40 with other commonly used inflammatory biomarkers. In this pilot case-control study, 45 term neonates (30 septic and 15 non-septic, as controls), 4 to 28 days old, were prospectively studied. The International Pediatric Sepsis Consensus Conference criteria were applied to diagnose sepsis. During the acute phase (admission) and remission of sepsis, blood samples were collected from cases (while from controls they were only collected once) for routine laboratory tests, cultures, and the measurement of serum YKL-40 levels via Elisa. In the acute phase of sepsis, YKL-40 levels were significantly elevated in comparison with remission (p = 0.004) and controls (p = 0.003). YKL-40 levels did not differ significantly between patients in remission and controls (p = 0.431). Upon admission, YKL-40 levels correlated positively with white blood count, absolute neutrophil count, and CRP levels. Via ROC analysis, it was shown that YKL-40 levels upon admission were a significant indicator of sepsis (AUC = 0.771; 95% CI 0.632-0.911; p = 0.003). Serum YKL-40 might be considered as an adjuvant biomarker of sepsis in term neonates.

Influence of pilot H[formula omitted] injection on methane-air swirled flame stabilization and acoustic response

Large Eddy Simulation is used to investigate the effect of localized pilot H2 injection on the Flame Transfer Function (FTF) of a premixed CH4-air swirled flame. The response of a perfectly premixed methane-air flame is compared to the one with an additional pilot hydrogen injection that supplies 10% of the original power. Numerical simulations are validated against experiments in terms of global FTF values at selected forcing frequencies, acoustic pressure and velocity signals, CH* flame images and flame root position dynamics. The unforced cases are first considered showing that, when H2 is injected in the center, the flame becomes slightly lifted with a localized diffusion front above the pilot injection. As in the experiments, LES retrieves that hydrogen pilot injection leads to a global redistribution of the heat release rate towards the flame root due to higher burning rates which translates to an overall FTF gain reduction over the entire frequency range explored. Then, the flame acoustic response for the two injection strategies is scrutinized at two distinct forcing frequencies: 240 Hz where the FTF gain difference is maximum, and 590 Hz where the FTF phase shift is maximum. LES reveals that, despite H2 pilot injection does not modify the dynamics of the large vortical structures shed in the external shear layer of the swiling jet which are synchronized by the acoustic forcing, the redistribution of the heat release rate towards the flame base weakens their interaction with the flame tip, explaining partly the FTF gain reduction at the two selected frequencies. In addition to that, a marked axial movement of the internal recirculation zone is observed at 240 Hz during the forcing cycle. For the pilot injection, it leads to an oscillation of the lifted flame root while, for the CH4-air case, the flame anchoring point is not affected. This additional oscillation leads for the pilot case to heat release rate fluctuations acting in phase opposition with respect to those observed at the flame tip, generating a further drop of the FTF gain at this specific frequency. The increased burning rate at the flame root and the flame length reduction of the pilot hydrogen flame also affect the characteristic time lag of the flame response. For both frequencies f = 240 Hz and 590 Hz, the phase shift between the two injection strategies is proportional to the flame length reduction caused by hydrogen injection. These simulations confirm that pilot hydrogen injection is an efficient way to reduce the acoustic response of swirled flames over a large frequency bandwidth.

Documentation, conservation, and reuse planning activities for disused cultural heritage

The present contribution illustrates the documentation and setting up of a digital database of a portion of Bellisomi-Vistarino Palace in Pavia (Italy), a relevant historical asset due to its artistic value. Despite recent restoration work, there are still disused portions of the complex, including the garden, the loggia and the rooms on the ground floor that overlook it. These portions are the elements this paper deals with. The approach to a small portion of the building is a pilot case from the perspective of a broader work of integral documentation of the whole complex. The aim is to define digital support for diagnostic and restoration planning activities from the perspective to enhance and create a new cultural attraction for the city, using the Foundation of the University of Pavia, already settled in the Palace and their organizational skills and networks. This is achieved by structuring a tridimensional digital twin and database connected to it to monitor the assets and generate digital environments for cultural and touristic valorisation.

Overview of Curcumin and Piperine Effects on Glucose Metabolism: The Case of an Insulinoma Patient’s Loss of Consciousness

The hypoglycemic properties of curcumin supplements in therapeutic doses are well-known and may represent a useful tool for the treatment of chronic diseases such as metabolic syndrome, insulin resistance and type 2 diabetes. The poor bioavailability of curcumin can be improved with the concomitant administration of piperine, with no severe adverse effects on glycemia reported so far in the literature. In this article, we further discuss a previously reported case of a helicopter pilot, affected by grade I obesity who, under curcumin and piperine treatment, experienced a transient loss of consciousness (TLOC), during a low-altitude flight. This episode led to a diagnosis of insulinoma, previously asymptomatic. We hypothesized that the combined effects of curcumin and piperine might have caused a severe hypoglycemic episode and subsequent TLOC. Therefore, further studies should be conducted to evaluate the safety of curcumin and piperine supplementation in subjects with impaired glucose metabolism and insulin secretion.

Impact of a Brief Mindfulness Training on Anxiety, Depression, and Subjective Happiness of the First-Year Psychology Students in Russia: Pilot Case Study of Ural Federal University

According to Russian researchers, university studies is among the most stressful activities for a person. First-year university students are particularly vulnerable to stress. The use of mindfulness-based programs to help students reduce and manage stress is gaining popularity around the world. Previous research has shown that such programs can improve the psychological well-being of students by reducing levels of anxiety and depression. In addition, students in helping majors, such as psychology students, would greatly benefit from mastering the skills of managing stress, as anxiety and stress are pertinent to their future profession. This pilot case study assesses the effectiveness of a brief mindfulness training aimed at improving Russian students’ mental and physical health. The participants were 83 first-year undergraduate students from the Psychology Department of the Ural Federal University named after B.N. Yeltsin. Data collection was completed in November 2019. A non-randomized controlled trial was conducted using a brief mindfulness training. The results show that the participants in the experimental group demonstrated significantly lower levels of depression (η2 = .07, p = .00) and significantly higher levels of subjective happiness (η2 = .02, p = .02) than participants in the control group. Also, the participants in the experimental group showed marginally significant lower levels of anxiety (η2 = .02, p = .06). Frequent mindfulness meditation practice and the study of theoretical materials were associated with higher rates of psychological well-being of students. The findings suggest that mindfulness training may be an effective tool in addressing psychological challenges experienced by first-year students of the Psychology Department of Ural Federal University.

Understanding the Use of Emerging Technologies in the Public Sector: A Review of Horizon 2020 Projects

The main purpose of this article is to provide an up-to-date understanding of the utilization and deployment of emerging technologies in the public sector, as this is reflected through 19 recently funded Horizon 2020 research projects. For the needs of this study, we have adopted a well-known literature review method that enables a concept-centric analysis of the accumulated knowledge in the field under consideration, and accordingly proposed a conceptual framework that facilitates such an analysis. Through a detailed consideration of these projects and their pilot case implementations, a series of insights about recent research development and applications in the public sector are extracted and discussed. To the best of our knowledge, this is the first attempt to gain such insights from a research projects perspective, which may reveal useful information about the utilization and deployment of these technologies in real-life pilots. The findings of this study are also justified or challenged by referring to recent review articles that investigate the use of emerging technologies in the public sector.

Stress and Workload Assessment in Aviation-A Narrative Review.

In aviation, any detail can have massive consequences. Among the potential sources of failure, human error is still the most troublesome to handle. Therefore, research concerning the management of mental workload, attention, and stress is of special interest in aviation. Recognizing conditions in which a pilot is over-challenged or cannot act lucidly could avoid serious outcomes. Furthermore, knowing in depth a pilot's neurophysiological and cognitive-behavioral responses could allow for the optimization of equipment and procedures to minimize risk and increase safety. In addition, it could translate into a general enhancement of both the physical and mental well-being of pilots, producing a healthier and more ergonomic work environment. This review brings together literature on the study of stress and workload in the specific case of pilots of both civil and military aircraft. The most common approaches for studying these phenomena in the avionic context are explored in this review, with a focus on objective methodologies (e.g., the collection and analysis of neurophysiological signals). This review aims to identify the pros, cons, and applicability of the various approaches, to enable the design of an optimal protocol for a comprehensive study of these issues.
