Authors: Araujo Andre Luis Calado , Ferraz Danilo Luiz de Magalhães , Vieira Cunha Paulo Eduardo , Fernandes Neto Cícero , Araújo da Silva Fernando José
Published: March 2018

An anaerobic (UASB) – hybrid aerobic (suspended and attached growth activated sludge) wastewater treatment system was evaluated on the removal of organic matter, solids and nitrogen following its pre-operational phase. Analysis were made weekly based on composite samples, prepared by grab samples taken every four hours, during 24-hour cycle, weighted by flow rate, on each monitoring point (raw sewage, UASB, anoxic chamber, aerobic reactors, return sludge from secondary decanters and final effluent). The plant presented an average flow rate of 908 m3/h with peaks from 10 to 14 h. BOD was removed by 86 % (310 to 41 mg/L) being the highest parcel accounted by UASB reactors (70 %) and removal of total suspended solids reached 63 % (190 to 94 mg/L). Mean removals of TKN (71 %) and Ammonium (77 %) were above the value predicted by design and, probably the nitrification-denitrification process was not the dominant route.
Przestępstwo cięższe przeciwko szóstemu przykazaniu Dekalogu z małoletnim – uwagi de lege lata i de lege ferenda
Authors: SKONIECZNY PIOTR
Published: March 2018

Autor komentuje poszczególne znamiona – przedmiotowe, podmiotowe i legalne – przestępstwa z art. 6 § 1 n. 1 SST/2010. Wskazuje na zmianę przedmiotu ochrony: od obowiązku celibatu w kan. 1395 § 2 CIC do mores w art. 6 SST/2010. Postuluje, zgodnie zresztą z tradycją kanoniczną, rozszerzenie znamiona sprawcy na na świeckich. Pochwala szerokie i teologiczne rozumienie znamienia czasownikowego („popełnienie przestępstwa przeciwko szóstemu przykazaniu Dekalogu”). Ustawodawca kościelny jednak niepotrzebnie precyzował, że chodzi o małoletniego do 18. roku życia, gdyż jest to zgodne z definicją legalną małoletniego w kan. 97 § 1 CIC. Z drugiej strony należy rozważyć rozróżnienie pedofilii w sensie ścisłym od efebofilii i od tego uzależnić karę. Ponadto zdaniem Autora nie ma uzasadnienia znamię trwałości co do innej ofiary przestępstwa, tj. osoby trwale ograniczonej w używaniu rozumu. Co do znamienia podmiotowego Autor zauważa różnicę między kodeksem łacińskim (przestępstwo tylko cum dolo) a wschodnim (także cum culpa) i kodeksami karnymi świeckimi, znającymi zamiar ewentualny (dolus eventualis, jak np. kodeks polski). Odnośnie do sankcji karnych Autor postuluje karę latae sententiae i przeszkodę do święceń za pedofilię sensu stricto oraz dostosowanie kan. 695 CIC do regulacji art. 6 SST/2010. W końcu proponuje rezygnację z instytucji derogacji terminów przedawnienia na rzecz instytycji nieprzedawnialności delicta graviora.
Driving Maximal Frequency Content and Natural Slopes Sharpening for Image Amplification with High Scale Factor
Authors: Delfin Leandro Morera , Elias Raul Pinto , Dominguez Humberto de Jesus Ochoa , Villegas Osslan Osiris Vergara
Published: March 2018

Background:

In this paper, a method for adaptive Pure Interpolation (PI) in the frequency
domain, with gradient auto-regularization, is proposed.

Methods:

The input image is transformed into the frequency domain and convolved with the Fourier
Transform (FT) of a 2D sampling array (interpolation kernel) of initial size L × M. The Inverse
Fourier Transform (IFT) is applied to the output coefficients and the edges are detected and counted.
To get a denser kernel, the sampling array is interpolated in the frequency domain and convolved
again with the transform coefficients of the original image of low resolution and transformed
back into the spatial domain. The process is repeated until a maximum number of edges is
reached in the output image, indicating that a locally optimal magnification factor has been attained.
Finally, a maximum ascend–descend gradient auto-regularization method is designed and
the edges are sharpened.

Results:

For the gradient management, a new strategy is proposed, referred to as the Natural bi-
Directional Gradient Field (NBGF). It uses a natural following of a pair of directional and orthogonal
gradient fields.

Conclusion:

The proposed procedure is comparable to novel algorithms reported in the state of the
art with good results for high scales of amplification.
New Emerging One Dimensional Nanostructure Materials for Gas Sensing Application: A Mini Review
Authors: Gupta Vinod Kumar , Alharbie Njud S. , Agarwal Shilpi , Grachev Vladimir A.
Published: March 2018

Background:

Nanomaterials have numerous potential applications in many areas such as electronics, optoelectronics, catalysis and composite materials. Particularly, one dimensional (1D) nanomaterials such as nanobelts, nanorods, and nanotubes can be used as either functional materials or building blocks for hierarchical nanostructures. 1D nanostructure plays a very important role in sensor technology.

Objective:

In the current review, our efforts are directed toward recent review on the use of 1D nanostructure materials which are used in the literature for developing high-performance gas sensors with fast response, quick recovery time and low detection limit. This mini review also focuses on the methods of synthesis of 1D nanostructural sensor array, sensing mechanisms and its application in sensing of different types of toxic gases which are fatal for human mankind. Particular emphasis is given to the relation between the nanostructure and sensor properties in an attempt to address structure-property correlations. Finally, some future research perspectives and new challenges that the field of 1D nanostructure sensors will have to address are also discussed.

Published: March 2018

BACKGROUND

Wrist-worn activity monitors are often used to monitor heart rate (HR) and energy expenditure (EE) in a variety of settings including more recently in medical applications. The use of real-time physiological signals to inform medical systems including drug delivery systems and decision support systems will depend on the accuracy of the signals being measured, including accuracy of HR and EE. Prior studies assessed accuracy of wearables only during steady-state aerobic exercise.

OBJECTIVE

The objective of this study was to validate the accuracy of both HR and EE for 2 common wrist-worn devices during a variety of dynamic activities that represent various physical activities associated with daily living including structured exercise.

METHODS

We assessed the accuracy of both HR and EE for two common wrist-worn devices (Fitbit Charge 2 and Garmin vívosmart HR+) during dynamic activities. Over a 2-day period, 20 healthy adults (age: mean 27.5 [SD 6.0] years; body mass index: mean 22.5 [SD 2.3] kg/m2; 11 females) performed a maximal oxygen uptake test, free-weight resistance circuit, interval training session, and activities of daily living. Validity was assessed using an HR chest strap (Polar) and portable indirect calorimetry (Cosmed). Accuracy of the commercial wearables versus research-grade standards was determined using Bland-Altman analysis, correlational analysis, and error bias.

RESULTS

Fitbit and Garmin were reasonably accurate at measuring HR but with an overall negative bias. There was more error observed during high-intensity activities when there was a lack of repetitive wrist motion and when the exercise mode indicator was not used. The Garmin estimated HR with a mean relative error (RE, %) of −3.3% (SD 16.7), whereas Fitbit estimated HR with an RE of −4.7% (SD 19.6) across all activities. The highest error was observed during high-intensity intervals on bike (Fitbit: −11.4% [SD 35.7]; Garmin: −14.3% [SD 20.5]) and lowest error during high-intensity intervals on treadmill (Fitbit: −1.7% [SD 11.5]; Garmin: −0.5% [SD 9.4]). Fitbit and Garmin EE estimates differed significantly, with Garmin having less negative bias (Fitbit: −19.3% [SD 28.9], Garmin: −1.6% [SD 30.6], P<.001) across all activities, and with both correlating poorly with indirect calorimetry measures.

CONCLUSIONS

Two common wrist-worn devices (Fitbit Charge 2 and Garmin vívosmart HR+) show good HR accuracy, with a small negative bias, and reasonable EE estimates during low to moderate-intensity exercise and during a variety of common daily activities and exercise. Accuracy was compromised markedly when the activity indicator was not used on the watch or when activities involving less wrist motion such as cycle ergometry were done.
How Well iPhones Measure Steps in Free-Living Conditions: Cross-Sectional Validation Study (Preprint)
Authors: Amagasa Shiho , Kamada Masamitsu , Sasai Hiroyuki , Fukushima Noritoshi , Kikuchi Hiroyuki , Lee I-Min , Inoue Shigeru
Published: March 2018

BACKGROUND

Smartphones have great potential for monitoring physical activity. Although a previous laboratory-based study reported that smartphone apps were accurate for tracking step counts, little evidence on their accuracy in free-living conditions currently exists.

OBJECTIVE

We aimed to investigate the accuracy of step counts measured using iPhone in the real world.

METHODS

We recruited a convenience sample of 54 adults (mean age 31 [SD 10] years) who owned an iPhone and analyzed data collected in 2016 and 2017. Step count was simultaneously measured using a validated pedometer (Kenz Lifecorder) and the iPhone. Participants were asked to carry and use their own iPhones as they typically would while wearing a pedometer on the waist for 7 consecutive days during waking hours. To assess the agreement between the two measurements, we calculated Spearman correlation coefficients and prepared a Bland-Altman plot.

RESULTS

The mean step count measured using the iPhone was 9253 (3787) steps per day, significantly lower by 12% (1277/10,530) than that measured using the pedometer, 10,530 (3490) steps per day (P<.001). The Spearman correlation coefficient between devices was 0.78 (P<.001). The largest underestimation of steps by the iPhone was observed among those who reported to have seldom carried their iPhones (seldom carry: mean −3036, SD 2990, steps/day; sometimes carry: mean −1424, SD 2619, steps/day; and almost always carry: mean −929, SD 1443, steps/day; P for linear trend=.08).

CONCLUSIONS

Smartphones may be of practical use to individuals, clinicians, and researchers for monitoring physical activity. However, their data on step counts should be interpreted cautiously because of the possibility of underestimation due to noncarrying time.
Types and Frequency of Infusion Pump Alarms: Protocol for a Retrospective Data Analysis (Preprint)
Authors: Glover Kevin R , Vitoux Rachel R , Schuster Catherine , Curtin Christopher R
Published: March 2018

BACKGROUND

The variety of alarms from all types of medical devices has increased from 6 to 40 in the last three decades, with today’s most critically ill patients experiencing as many as 45 alarms per hour. Alarm fatigue has been identified as a critical safety issue for clinical staff that can lead to potentially dangerous delays or nonresponse to actionable alarms, resulting in serious patient injury and death. To date, most research on medical device alarms has focused on the nonactionable alarms of physiological monitoring devices. While there have been some reports in the literature related to drug library alerts during the infusion pump programing sequence, research related to the types and frequencies of actionable infusion pump alarms remains largely unexplored.

OBJECTIVE

The objectives of this study protocol are to establish baseline data related to the types and frequency of infusion pump alarms from the B. Braun Outlook 400ES Safety Infusion System with the accompanying DoseTrac Infusion Management Software.

METHODS

The most recent consecutive 60-day period of backup hospital data received between April 2014 and February 2017 from 32 United States-based hospitals will be selected for analysis. Microsoft SQL Server (2012 - 11.0.5343.0 X64) will be used to manage the data with unique code written to sort data and perform descriptive analyses. A validated data management methodology will be utilized to clean and analyze the data. Data management procedures will include blinding, cleaning, and review of existing infusion data within the DoseTrac Infusion Management Software databases at each hospital. Patient-identifying data will be removed prior to merging into a dedicated and secure data repository. This pooled data will then be analyzed.

RESULTS

This exploratory study will analyze the aggregate alarm data for each hospital by care area, drug infused, time of day, and day of week, including: overall infusion pump alarm frequency (number of alarms per active infusion), duration of alarms (average, range, median), and type and frequency of alarms distributed by care area.

CONCLUSIONS

Infusion pump alarm data collected and analyzed in this study will be used to help establish a baseline of infusion pump alarm types and relative frequencies. Understanding the incidences and characteristics of infusion pump alarms will result in more informed quality improvement recommendations to decrease and/or modify infusion pump alarms, and potentially reduce clinical staff alarm fatigue and improve patient safety.

PROBLEMATIKA PENYELESAIAN SENGKETA KEWENANGAN LEMBAGA NEGARA OLEH MAHKAMAH KONSTITUSI
Authors: Simamora Janpatar
Published: March 2018

According to Article 24C verse (1) of the 1945 Constitution, Constitutional court has an authority to examine the dispute among the state institution in which its authority is given by the constitution directly. But there is a certain problem in practice which is related to definition of “state institution” and “authorities are granted the Constitution” in the 1945 Constitution. This condition opens a debate the interpretation in executing the settlement on authority dispute among the institutions. In addition, should be considered the settlement of disputes the authority of institutions, whose authority derived from regulation other than the Constitution Menurut ketentuan Pasal 24C ayat (1) UUD NRI Tahun 1945, penyelesaian sengketa kewenangan lembaga negara yang kewenangannya diberikan oleh UUD merupakan kewenangan Mahkamah Konstitusi. Namun dalam praktiknya, proses penyelesaian sengketa kewenangan lembaga negara menghadapi problem tersendiri seiring tidak adanya batasan ruang lingkup dan definisi “lembaga negara” dan frasa “kewenangannya diberikan UUD” secara pasti dalam UUD NRI Tahun 1945. Situasi ini pada akhirnya menimbulkan multitafsir yang berpotensi mengakibatkan tidak efektifnya penyelesaian sengketa kewenangan lembaga negara di Indonesia. Selain itu, perlu dipikirkan mekanisme penyelesaian sengketa kewenangan lembaga yang kewenangannya bersumber dari peraturan selain UUD.

The role of members’ commitment on agri-food co-operatives’ capitalization, innovation and performance
Authors: Marcos-Matas Gustavo , Ruggeri Arianna , Ghelfi Rino
Published: March 2018

Undercapitalization has been recognized as a problem affecting Italian co-operatives to perform in modern agri-food markets. An empirical study on 50 Italian agri-food co-operatives was carried out to investigate co-operatives members’ commitment capability to impact on the level of capitalization. The level of capitalization was also investigated as a mean to influence co-operatives’ innovation and subsequently their performance. The results show how co-operatives with more committed memberships display higher levels of capitalization and that capitalization positively relates with innovation levels. The latter is also confirmed to enhance co-operatives’ performance. These results are relevant from a managerial point of view as they reveal the importance of members’ commitment in this particular type of organizations and provide new insights to improve co-operatives’ innovation and performance.

Many popular iterative algorithms have been used to approximate fixed point
of contractive type operators. We define the concept of generalized ?-weakly
contractive random operator T on a separable Banach space and establish
Bochner integrability of random fixed point and almost sure stability of T
with respect to several random Kirk type algorithms. Examples are included
to support new results and show their validity. Our work generalizes,
improves and provides stochastic version of several earlier results by a

Monotonicity results for delta and nabla caputo and Riemann fractional differences via dual identities
Authors: Abdeljawad Thabet , Abdalla Bahaaeldin
Published: March 2018

Recently, some authors have proved monotonicity results for delta and nabla
fractional differences separately. In this article, we use dual identities
relating delta and nabla fractional difference operators to prove shortly the
monotonicity properties for the (left Riemann) nabla fractional differences
using the corresponding delta type properties. Also, we proved some
monotonicity properties for the Caputo fractional differences. Finally, we
use the Q??operator dual identities to prove monotonicity results for the
right fractional difference operators.

Published: March 2018

The main object of this paper is to present a systematic introduction to the
theory and applications of the extended Appell-Lauricella hypergeometric
functions defined by means of the extended beta function and extended
Dirichlet?s beta integral. Their connections with the Laguerre polynomials,
the ordinary Lauricella functions and the Srivastava-Daoust generalized
Lauricella functions are established for some specific paramters.
Furthermore, by applying the various methods and known formulas (such as
fractional integral technique; some results of the Lagrange polynomials), we
also derive some elegant generating functions for these new functions.

Conditions for approaching the origin without intersecting the x-axis in the Liénard plane
Authors: Aghajani Asadollah , Mirafzal Mohsen , O’Regan Donald
Published: March 2018

We consider the Li?nard system in the plane and present general assumptions
to obtain some new explicit conditions under which this system has or fails
to have a positive orbit which starts at a point on the vertical isocline
and approaches the origin without intersecting the x-axis. This arises
naturally in the existence of homoclinic orbits and oscillatory solutions.
Our investigation is based on the notion of orthogonal trajectories of
orbits of the system.

category of proximity spaces. Moreover, specific relationships that arise
among the various Ti,i = 0,1,2 and PreT2 structures are examined in this

method for solving the split common fixed point problem of two infinite
families of k-demicontractive mappings. We shall also study the split common
null point problem, and the split equilibrium problem for this class of
mappings. As an application, we obtain strong convergence theorems for the
split monotone variational inclusion problem and the split variational
inequality problem. Our results improve and extend the recent results of Cui

A Matlab/Simulink 3D model of unsymmetrical ultrasonic sandwich transducers
Authors: Jovanovic Igor , Jovanovic Ugljesa , Mancic Dragan
Published: March 2018

Ultrasonic sandwich transducer is a half-wave resonant structure which
oscillates in thickness direction. This paper presents a new Matlab/ Simulink
model of a prestressed unsymmetrical ultrasonic sandwich transducer, which is
modeled by applying three-dimensional (3D) Matlab/Simulink models of
piezoceramic rings and metal endings derived from the piezoceramic ring
model. With the cascade connection of the piezoceramic rings model with metal
endings model, a complete model of ultrasonic transducer is obtained. Using
this model one may determine any transducer transfer function, whereat is
taken into the account the external medium influence, as well as the
influence of the thickness and radial modes of each transducer component. The
electromechanical equivalent circuit of the hammer transducer, which
represents onedimensional (1D) model, is also derived and presented in this
paper. The comparisons between experimental and theoretical results are quite
good and validate the new analytical 3D design approach.
Improved dehazing techniques for maritime surveillance image enhancement
Authors: Stojanovic Branka , Milicevic Sasa , Stankovic Srdjan
Published: March 2018

The subjective quality of images (human interpretation) is very important in
long-range imaging systems, where the presence of haze directly influences
visibility of the scene, by reducing contrast and obscuring objects. Image
enhancement techniques - dehazing techniques, are usually required in such
systems. This paper compares the most significant single image dehazing
approaches, proposes three additional enhancement steps in dehazing
algorithms, compares performance of the algorithms and additional
enhancement steps, and presents test results on maritime surveillance
images, which represent one special case of long-range images.

Food Insecurity, Food “Deserts,” and Glycemic Control in Patients With Diabetes: A Longitudinal Analysis
Authors: Berkowitz Seth A. , Karter Andrew J. , Corbie-Smith Giselle , Seligman Hilary K. , Ackroyd Sarah A. , Barnard Lily S. , Atlas Steven J. , Wexler Deborah J.
Published: March 2018

OBJECTIVE

Both food insecurity (limited food access owing to cost) and living in areas with low physical access to nutritious foods are public health concerns, but their relative contribution to diabetes management is poorly understood.

RESEARCH DESIGN AND METHODS

This was a prospective cohort study. A random sample of patients with diabetes in a primary care network completed food insecurity assessment in 2013. Low physical food access at the census tract level was defined as no supermarket within 1 mile in urban areas and 10 miles in rural areas. HbA1c measurements were obtained from electronic health records through November 2016. The relationship among food insecurity, low physical food access, and glycemic control (as defined by HbA1c) was analyzed using hierarchical linear mixed models.

RESULTS

Three hundred and ninety-one participants were followed for a mean of 37 months. Twenty percent of respondents reported food insecurity, and 31% resided in an area of low physical food access. In adjusted models, food insecurity was associated with higher HbA1c (difference of 0.6% [6.6 mmol/mol], 95% CI 0.4–0.8 [4.4–8.7], P < 0.0001), which did not improve over time (P = 0.50). Living in an area with low physical food access was not associated with a difference in HbA1c (difference 0.2% [2.2 mmol/mol], 95% CI −0.2 to 0.5 [−2.2 to 5.6], P = 0.33) or with change over time (P = 0.07).

CONCLUSIONS

Food insecurity is associated with higher HbA1c, but living in an area with low physical food access is not. Food insecurity screening and interventions may help improve glycemic control for vulnerable patients.

LIPSIA 1522 L’EPITAFFIO SCHMIDBURG DI GEORG LEMBERGER RELIGIONE, POLITICA E PITTURA
Authors: ANGELUCCI Giulio

Leipzig 1522 Epitaful Schmidburg de Georg Lemberger, Religie, politică și pictură. Articolul propune prezentarea preliminariilor la studiul comparativ efectuat asupra Epitafului Schmidburg de Georg Lemberger, aflat acum în Museum der Bildenden Künste din Leipzig și pus apoi față în față cu Crucificarea lui Lorenzo Lotto de la Monte San Giusto. Cele două picturi se referă la medii sociale și culturale foarte diferite, sunt dintotdeauna situate la mai mult de o mie de kilometri distanță una de alta și în contrast din punct de vedere stilistic, religios și al publicității destinației. Ele sunt unite de singularitatea unei structuri compozitive în care conviețuiesc trei tipuri diferite ale reprezentării vizuale, așezate în aceeași ordine a succesiunii: Icoana (cele trei cruci în partea superioară), Ilustrarea (traducerea în imagine a povestirii evanghelice în partea din mijloc) și Povestirea de invenție (în partea inferioară, unde contextul în care este așezată figura clientului dă cheia de interpretare politică a picturii). Sunt propuse aici două paragrafe ale studiului citat, intitulat Lorenzo Lotto vs. Georg Lemberger. Două picturi politice de subiect religios în jurul anului 1525. Amândouă paragrafele se concentrează asupra analizei registrului inferior al operei germane, primul finalizat spre delimitarea caracteristicilor Povestirii de invenție sub înfățișarea aparentă a imitației naturaliste, cel de-al doilea îndreptat către delimitarea conținuturilor introduse într-o astfel de povestire. Amestecul registrelor narative a rezultat ca echivalentul artificiului oratoriu la care s-a recurs, modulând vocea pentru a deosebi povestirea de interpretare. În lumina unei astfel de constatări, conținuturile implicite pe care studiul le-a identificat în registrele inferioare ale celor două opere au evidențiat detalii importante depistate în respectivele registre superioare. Pozițiile asumate de către autori în ceea ce privește propunerile luterane au adus la lumină respingerea din partea lui Lotto a pozițiilor teologice ilustrate de Lemberger.

Contributions Regarding the Portrait of Sigismund of Luxembourg from the Gate of the Monastery in Brașov. The study provides data on the portrait of Sigismund of Luxembourg, located on the Monastery Gate in Brașov between the 16th and 19th centuries. A large wall painting, the portrait disappeared after the demolition of the gate in the years 1835-1836. The details of the mural painting depicting Sigismund of Luxembourg have so far remained largely unknown. Starting from a photograph, preserved at the Brașov County Administration of the National Archives, a reproduction of an easel painting, a true copy of the murals, the study reconstructs the aspect of the mural painting. The portrait of Sigismund of Luxembourg is one of the most important works of secular mural painting from 16th century Transylvania and remains so far unpublished in the speciality literature dedicated to the iconography of Sigismund of Luxembourg.
CONSIDERAȚIILE UNUI PICTOR DESPRE TRECEREA PICTURII DE LA FAYUM LA ARTA BIZANTINĂ
Authors: BELEAN Carmen

Le considerazioni di un pittore sul passaggio della pittura di Fayum alla pittura bizantina. La pittura dell’antichità rimane un soggetto sempre aperto grazie, da una parte, alle poche fonti quali abbiamo per indagare la complessità e la sua ampiezza, e da un altra parte, grazie alla qualità eccezionale delle fonti alle quali abbiamo pure accesso. Un notevole momento sul tragitto della pittura dell’antichità si ritrova nel periodo tra i secoli II e III prima e dopo Cristo, nella forma di alcuni ritratti funebri. Il più di 1000 dipinti scoperti nella regione Fayum, quali rappresentano ritratti dipinti su legno oppure su strisce di papiro, portano oggi il nome della regione in cui sono stati scoperti. Questi lavori rappresentano veri esempi di arte Copta ed evidenziano un momento particolare come inovazione e forma di espressione sul cammino della pittura naturalistica. Una serie di segni concludenti attestano il fatto che questo tipo di pittura si trova alla base della pittura religiosa di icone dei secoli successivi, evidenti specialmente nelle somiglianze multipli quali questi ritratti hanno con la icona. I ritratti di Fayum e le prime icone cristiane dovessero coesistere fino all’estinzione finale del culto dei ritratti di mumie. Anche se l’evidenza è frammentaria, possiamo pure osservare la transizione dall’arte pagana a quella cristiana nel mondo romano, in icone datando dei secoli VI e VII d.Hr. quali provengono dal monastero Santa Caterina al Monte Sinai per esempio, quali rappresentano una forte somiglianza con questi ritratti pagani.
Parole chiave: pittura dell’Antichità, pittura di Fayum, la scuola di Alessandria, la pittura bizantina, la tecnica encaustica, l’icona.
ÎNTREBĂRI PENTRU UN ARTIST PLASTIC ROMÂN LA CĂDEREA COMUNISMULUI
Authors: MÂNDRESCU Gheorghe
Published: March 2018

Domande per un artista plastico rumeno alla caduta del comunismo (per potersi scrivere una storia riguardante l’arte nell’epoca). All’artista, nel comunismo gli fu tolta la libertà di creazione, di aprire nuove vie, verso nuovi orizzonti. Un esercito di attivisti dilettanti oppure opportunisti, fanatici ideologici e agenti della temuta Securitate lo hanno trasformato in uno strumento di propaganda. Utile per le locandine comuniste "mobilitanti" oppure alle scenografie trionfalisti delle sfilate quali dovevano otturare le finestre aperte verso la verità. L’artista fu allontanato dal collezionista, diventato una quantità trascurabile. Il collezionista, il più grande investitore, la riserva per la futura selezione del museo fu sostituito con l’ispettore del Comitato di Cultura ed Educazione Socialista, il sorvegliante quale gli assicurava l’esistenza quotidiana solo se si addatava alla linea desiderata dagli esecutori più o meno abili, degli slogan della lotta di classe. In mancanza dell’educazione artistica nella scuola, nella società, in chiesa, in mass-media, l’ambiente sociale è diventato sempre più insensibile per apprezzare la scala dei valori del passato oppure del presente. Tutte queste hanno impoverito un intero popolo e hanno limitato evidentemente il contributo dell’universo pittorico all’evoluzione culturale dell’intera nazione. Senza punti di riferimento rispettati, del passato, l’arte contemporanea per la maggioranza degli uomini, ha navigato tra i segni lanciati, come una scattola pubblicitaria, ripetutamente sul modello Cântarea României (Il Cantico alla Romania, n.d.tr.). I risultati si vedono oggi e hanno segnato miserabilmente la reazione della maggioranza al testo proposto tramite l’acquisizione attraverso contributo pubblico della pregiata scultura Cumințenia Pământului, (Assenatezza della terra, n.d.tr.) appartenendo al più conosciuto artista contemporaneo Constantin Brâncuși, al quale fu rifiutata la donazione allo stato rumeno del suo studio di Parigi negli anni ’50. La rinascita spirituale del paese non si può fare senza un investimento di lunga durata tramite la scuola e i media come un orientamento prioritario, sostenuto anche dall’attualità politica ancora sofferente dalla maniera totalitaria difusa nell’intervallo della dominazione comunista. Parole chiave: La libertà dell’artista, la propaganda, attivista di partito, Securitate, educazione socialista, Constantin Brâncuși.
Comparison of the use of fresh-frozen canine cadavers and a realistic composite ex vivo simulator for training in small animal flexible gastrointestinal endoscopy

OBJECTIVE To compare the usefulness of fresh-frozen canine cadavers (FFCCs) and a validated canine simulator model for training veterinary students in basic gastrointestinal endoscopic procedures.

DESIGN Randomized trial.

SAMPLE 48 veterinary students in their final year of training.

PROCEDURES Students were randomly assigned to receive basic gastrointestinal endoscopic training on a canine simulator or FFCC. All students were trained as assigned in esophagogastroduodenoscopy, endoscopic gastric biopsy, and gastric foreign body removal for 2 h/d for 5 days. They then performed each procedure on a live dog, and procedure completion time and performance ability were compared between groups. Two experienced endoscopists used a validated Likert-type procedural rating scale to rate the students' performance. Students completed a survey to rate their training model.

RESULTS No significant differences were identified between groups in quality of performance of the 3 endoscopic procedures on a live dog. Students required significantly less time to complete the procedures on a live dog when trained on an FFCC versus canine simulator. Although both training models were considered equally useful by students, training on the simulator was significantly more stimulating.

CONCLUSIONS AND CLINICAL RELEVANCE Students showed the same skill level in performing basic endoscopic procedures on live dogs regardless of the training model used, although students who trained on the FFCC completed these procedures faster than students trained on the canine simulator. Use of the simulator appeared to be a viable alternative to use of FFCCs for veterinary endoscopic training, providing students with a good level of proficiency before performing endoscopic procedures on live dogs.
