Background:In knee osteoarthritis (KOA) recommendations, the first pharmacological analgesic line is paracetamol. However, its low efficacy, frequently leads to the use of weak opioids (WO) despite their poor tolerance, especially in elderly patients.Objectives:The primary objective was to compare analgesic efficacy and safety of a new wearable transcutaneous electrical nerve stimulation (W-TENS) to those of WO in the treatment of moderate to severe, nociceptive, chronic pain in KOA patients.Methods:ArthroTENS study was a phase 3, non-inferiority, multicentric, prospective, randomized, single-blinded for primary efficacy outcome, controlled, in 2-parallel groups, clinical study comparing W-TENS versus WO on two periods: a 3-month controlled period and an additional, optional, non-controlled, 3-month follow-up for patients in W-TENS group.Eligible participants were KOA patients, ≥55 years old, at Kellgren-Lawrence radiographic grade ≥2, with moderate to severe nociceptive chronic (≥3 months) mean 8-day pain ≥4 on a 11-point numerical rating scale, and in treatment failure with non-opioid analgesics, including NSAIDs. Patients with neuropathic pain were excluded.Co-primary endpoints were, for efficacy, mean pain intensity (PI), assessed at M3 and, for safety, the number of adverse events (AE) during the 3-month follow-up period.In W-TENS group, an advanced, mobile app enabled, wearable TENS was used. High (100 Hz) and low (2 Hz) frequency stimulations were delivered via electrodes with standardized positioning (Figure 1).Figure 1.Electrode’s positioningIn WO group, investigators chose, for each patient, the best suitable WO and its daily dose, and could switch to another WO, and/or adapt its daily dose if necessary.A non-inferiority analysis was performed on the primary efficacy endpoint using a pre-defined non-inferiority margin (0.825 point) on PI, below the minimal clinically significant improvement.Results:Demographic and baseline characteristics were balanced across both groups.110 patients (55/group) were randomized and 48/55 (87.3%) and 44/55 (80.0%) patients completed the 3-month follow-up in W-TENS and WO groups, respectively. WO’s prescriptions were balanced between codeine, opium-powder, tramadol and WO-paracetamol combinations.Non-inferiority of W-TENS was demonstrated in the PP and ITT populations (Table 1). Since the 95% confidence interval (CI) of the between-treatments difference was below 0 in the ITT population, a planned superiority analysis was performed showing that W-TENS was significantly superior to WO at M3 (p=0.0124) on PI. Additionally, the number of AEs was significantly lower (p<0.001) in W-TENS (n=7) group than in WO (n=36) group. In WO group, AEs were systemic AEs usually reported with WO while AEs in W-TENS group were local, related to the technique used, such as local cutaneous reaction (erythema).Table 1.Non-inferiority analyses on pain intensity at M3.

Only one patient discontinued this additional period and results obtained at M3 remained stable at M6.Conclusion:In this study, W-TENS was more effective and better tolerated than WO in the treatment of nociceptive KOA chronic pain and should represent an interesting non-pharmacological alternative to WO.Acknowledgements:We gratefully thank P.

Abstract Background: Follow-up reports describing the long-term prognosis of 47 patients with epoetin induced PRCA have been confined to a single study from France, England, and Germany, investigated through active surveillance efforts. There is concern that reporting quality may differ between active versus voluntary reporting efforts. Methods: Investigators from the Research on Adverse Drug reactions And Reports (RADAR) program compared clinical findings for epoetin-associated PRCA cases reported by voluntary surveillance efforts (n= 47) versus active surveillance (n= 47). (Verhelst et at, Lancet 2004). Recovery from PRCA was defined as transfusion independence, normalized reticulocyte count, and/or disappearance of anti-erythropoietin antibody. Results: Baseline characteristics of age and gender were similar in both the MEDWatch and active surveillance groups. The two groups were similar with respect to median age similar (67 years) and gender (70%) and follow-up duration for patients who recovered (mean of 3 months). Median follow-up was shorter for passive surveillance patients who did not recover (6 versus 11 months). Recovery rates with immunosuppression differed (39.5% for MedWatch versus 21.6% for active surveillance). Conclusions: Follow-up of active versus passive pharmacovigilance differed markedly for epoetin-associated PRCA cases in France, Germany, and the UK, in part due to differences in follow-up time. Active pharmacovigilance efforts should be supported by national health authorities.

Abstract The Institute for Nuclear Safety and Protection (IPSN) launched the « Tournemire » program, in 1988. One of its aims is to understand and characterize the fluid transfer processes in argillaceous rocks. They are interesting rocks for the long-term storage of nuclear waste. To this purpose, the IPSN installed an experimental site in a tunnel, which gives access to a 250 m-thick Toarcian and Domerian shale unit near Tournemire (Aveyron, France) (fig. 1). The fluids, in this type of rock with very low intrinsic permeability, 10−14 m/s [Boisson et al., 1998], used to flow (calcite crystallizations in fractures), and still flow, principally in the fractures [Barbreau et Boisson, 1993 ; Boisson, 1995] formed during the tectonic history of the formation. In order to constrain the history of fluid flow in the formation, it was necessary to characterize the tectonic fracturing and to identify the tectonic events responsible, on the one hand, for the apparition of the fractures and, on the other hand, for their eventual reactivation. The method used was a microtectonic and kinematic analysis. The studied area belongs to the western border of the Causses basin, a Permian-Mesozoic basin trending N-S. The slightly monoclinal series in this area range from the Trias, discordant westward on the Permian formations of the St-Affrique basin, to the lower Kimmerigian locally present on the Larzac plateau (fig. 1). The upper Liassic shales (Domerian, Toarcian) are between two limestone and dolomite formations. Two major (regional-scale) ESE-WNW reverse faults, the Cernon fault and the St-Jean-d’Alcapies fault, cross the area. Their offsets may reach several hundred meters. These two faults limit an ESE-WNW trending block where the experimental site is located. The tectonic fractures in the area result from two main tectonic phases. Phase 1, extensional, occurred during the Mesozoic and comprises three episodes (fig. 2). The first episode, characterised by an E-W extension (fig. 3), did not produce significant structures in the Toarcian shales. The second episode, with a NW-SE extension direction (fig. 4 and fig. 5), occurred during the diagenesis of the shales. It led to the development of calcareous nodules. These nodules are considered to be « mode I » fractures formed in association with fluid expulsion during the sediment compaction (fig. 4). The last episode has a N-S direction, (fig. 7) and is probably late Jurassic in age [Macquar, 1973 ; Blès et al., 1989 ; Martin et Bergerat, 1996]. It produced E-W conjugate normal faults (fig. 6) and two perpendicular sets of extensional joints trending E-W and N-S. The second major tectonic phase corresponds to the « pyrenean » compression. The σ1 directions vary from NE-SW to NW-SE, with two major pulses striking N020-N030 and N160-N170 (fig. 2, fig. 9 and fig. 10). The N020-N030 direction corresponds to the paroxysm of the « pyrenean » phase, dated as late Middle Eocene [Arthaud et Laurent., 1995]. It reactivated major faults and formed associated folds (fig. 8). Numerous fractures due to the N160-170 compressional event are concentrated principally in the center of the block bordered by the ESE-WNW major faults (fig. 2). Chronological criteria indicate that the direction of compression rotated counter-clockwise during the « pyrenean » compressional phase (fig. 11). A third compression direction (N130) has been evidenced, for example, by N030 trending tension gashes cross-cut by N130 trending gashes (fig. 12). The significance of this last tectonic event is unclear. It is mainly observed in the west drift of the experimental site (fig. 1C), and could result of the re-orientation of the stresses at this site close to an important shear zone. Three sets of joints, trending N020, N160 and N090 (fig. 13 and fig. 14) have been recognized. The joints are classically extensional fractures that propagate perpendicular to the minimum principal stress σ3 [Endelger, 1985 ; Pollard et Aydin, 1988 ; Rives, 1992]. In strike-slip regimes, such fractures strike parallel to the maximum principal stress σ1. The average N020, N160 and N090 joints thus very probably are created respectively during the N020 pyrenean strike-slip event, N160 strike-slip event and N-S Mesozoic extension. The established chronology between the different compressional episodes involves the reactivation of the N020 and N160 fractures may have caused only senestral strike slip. However, the presence of dextral strike slip on some vertical planes trending N-S, not associated with conjugate planes but with E-W vertical planes indicates their origin is not related to the « Pyrenean » phase. Consequently, we assumed that a set of N-S joints created during the extensive phase, in the same time as the E-W joints. An elasticity theory model gives an account of field observations on this type of fractures. The model proposed by Caputo [1995] describes the geometry of networks, of joints as a function of the tectonic regime (fig. 15). Two coeval sets of joints form under the same tectonic event. For an extensive stress state, the two sets are orthogonal to each other. Under strike slip regimes, two orthogonal sets form but one of the two sets forms horizontally (parallel to the bedding planes when the stratification is horizontal). The mechanism involves a stress permutation between σ3 and σ2 in the vicinity of the first fracture zone at the moment of failure. The network of orthogonal joints (N-S and E-W) appeared under the N-S extensive event. We show two sets of joints with the same orientation formed at two different ages (fig. 16). Their differentiation was possible with the chronology of the deformation, which was determined by the microtectonic analysis. The pre-existing fractures, originated before the « pyrenean » phase, necessarily influenced the expression and the distribution of the fractures associated with the « pyrenean » phase. These pre-existing fractures must be taken into account to understand and constrain the fluid circulations in the Toarcian shales.

Abstract. An automated atmospheric river (AR) detection algorithm is used for the North Atlantic Ocean basin, allowing the identification of the major ARs affecting western European coasts between 1979 and 2012 over the winter half-year (October to March). The entire western coast of Europe was divided into five domains, namely the Iberian Peninsula (9.75° W, 36–43.75° N), France (4.5° W, 43.75–50° N), UK (4.5° W, 50–59° N), southern Scandinavia and the Netherlands (5.25° E, 50–59° N), and northern Scandinavia (5.25° E, 59–70° N). Following the identification of the main ARs that made landfall in western Europe, a Lagrangian analysis was then applied in order to identify the main areas where the moisture uptake was anomalous and contributed to the ARs reaching each domain. The Lagrangian data set used was obtained from the FLEXPART (FLEXible PARTicle dispersion) model global simulation from 1979 to 2012 and was forced by ERA-Interim reanalysis on a 1° latitude–longitude grid. The results show that, in general, for all regions considered, the major climatological areas for the anomalous moisture uptake extend along the subtropical North Atlantic, from the Florida Peninsula (northward of 20° N) to each sink region, with the nearest coast to each sink region always appearing as a local maximum. In addition, during AR events the Atlantic subtropical source is reinforced and displaced, with a slight northward movement of the sources found when the sink region is positioned at higher latitudes. In conclusion, the results confirm not only the anomalous advection of moisture linked to ARs from subtropical ocean areas but also the existence of a tropical source, together with midlatitude anomaly sources at some locations closer to AR landfalls.

Abstract. An automated atmospheric rivers (ARs) detection algorithm is used for the North Atlantic Ocean Basin allowing the identification of the major ARs that affected western European coasts between 1979 and 2014 over the winter half-year (October to March). The entire west coast of Europe was divided into five domains, namely, the Iberian Peninsula (9.75° W; 36–43.75° N), France (4.5° W; 43.75–50° N), UK (4.5° W; 50–59° N), southern Scandinavia and the Netherlands (5.25° E; 50–59° N), and northern Scandinavia (5.25° E; 59–70° N). Following the identification of the main ARs that made landfall in western Europe, a Lagrangian analysis was then applied in order to identify the main sources of moisture that reach each domain. The Lagrangian dataset used was obtained from the FLEXPART model global simulation from 1979 to 2012, where the atmosphere was divided into approximately 2.0 million parcels, and it was forced by ERA-Interim reanalysis on a 1° latitude–longitude grid. Results show that, in general, for all regions considered, the major climatological source of moisture extends along the subtropical North Atlantic, from the Florida Peninsula (northward of 20° N), to each sink region, with the nearest coast to each sink region always appearing as a local maximum of evaporation. In addition, during the AR events, the Atlantic subtropical source is reinforced and displaced, with a slight northward movement of the moisture sources is found when the sink region is positioned at higher latitudes. In conclusion, the results confirm the advection of moisture linked to ARs from subtropical ocean areas, but also the existence of a tropical one, and the mid-latitude sources further the analysed longitude along the North Atlantic is located eastward.

Abstract. Mesospheric wind profiles with an altitude resolution of 25 m have been obtained by means of radar tracking of foil chaff clouds. Such experiments were performed during winter 1990 at Biscarrosse, France (44°N, 1°W). On one flight, a wind shear as high as 330 m s–1 km–1 at 87.4 km and a region of dynamical instability between 86 and 88 km was measured. This wind shear is believed to be the largest value ever measured in the mesosphere. The region of dynamical instability results from a superposition of two wave motions, and is found to link well with enhanced turbulence and small-scale wave activity.

Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. Loess is a last step eolian transported, fine grained sediment and can be a good record as a Quaternary climate archive (Muhs 2013; Stevens et al. 2020). Loess-paleosol sequences can be used as a relative record for climate change. The paleosols in the sequence corresponds to soil which can indicate warmer interglacial/interstadial periods when chemical weathering was active at site. Loess in these sequences reflects on cold and dry climate during glacial periods (Buggle et al. 2008; Muhs 2013). By analyzing geochemical composition of bulk-samples from chosen site one can get information about if paleosols or loess deposits are present at certain depths of profile. Also, if a glacial or interglacial period was present then (Buggle et al. 2011; Johansson 2017). In this study X-ray fluorescence Spectroscopy (XRF), will be used to analyze elemental composition of loess. This to see how soluble and mobile elements relate to immobile and non-soluble ones. This can indirectly tell how paleosols and loess are distributed over the site and if shifts attempt by depth. The samples of loess in this study were taken from north-western France at a site called Primel-Tregastel. Soil weathering indexes will be used in this study to calculate weathering intensities for deposit. Na/Al-based indices called CIA, CIW, CPA, PIA, Index B and Sr-based ratios Ba/Sr and Rb/Sr was used (Buggle et al. 2011). The purpose of the study is to see if weathering has been active at site. And if, to reconstruct at which depths and to make a paleoclimatic interpretation of the site. Na/Al-based indices CIA, CIW, CPA, PIA and Index B shows indications of active weathering at site. Sr-based ratios Ba/Sr and Rb/Sr do also show same indications but with more dramatically variations. The content of mobile and immobile elements does also follow the principle that when mobile elements decrease in percentage, immobile elements get enriched in bulk-sample. The trends shown are a long time of cold climate due to low weathering intensities followed by one warmer and more humid period. Increasing weathering intensities, indicating an interglacial/interstadial period happens as a first development. Continuously a decrease happens in weathering intensity which would indicate a start of a colder period. Topmost layer has been improved and re-worked by human activity and will be misleading to use in a geochemical analysis and paleoenvironmental interpretation.
Att analysera klimatförändringar genom lössjordar formade efter senaste glaciala maximumet ger oss information om hur miljön såg ut dynamiskt innan människan hade möjligheten att mäta klimatvariationer. Genom analys och provtagning av lössjordar från olika platser i världen ger oss en mer trovärdig bild över när händelser och förändringar i klimat skedde. Lössjord är ett slutligen vindtransporterad, finkornigt sediment som även fungerar bra som register för Kvartära klimatarkiv (Muhs 2013; Stevens et al. 2020). Loess-paleosol sekvenser kan användas som ett relativt register för klimatförändringar. Paleosolerna i sekvensen motsvarar jord som indikerar varmare interglaciala/interstadiala perioder när kemisk vittring kan ha varit aktiv. Lössavlagringar i sekvensen reflekterar kallare och torrare klimat under glaciala istider (Buggle et al. 2008; Muhs 2013). Genom att analysera geokemiskt innehåll av prover från lokal kan man få fram information om paleosoler eller lössavlagringar finns vid visst djup i profilen. Indirekt även om en glacial eller interglacial period pågick då (Buggle et al. 2011; Johansson 2017). I den här studien används X-ray fluorescens Spektroskopi (XRF) för att analysera geokemiskt innehåll av lössjord. Detta för att se hur lösliga och mobila element är relaterade till icke-mobila och icke-lösliga element. Det kan indirekt peka på hur paleosoler och löss är fördelat över en lokal och visa om skillnader finns vid olika djup. Proverna i denna studie är tagna från nord-västra Frankrike vid en lokal som heter Primel Trégastel. Jord vittrings index kommer att användas i studien för att beräkna vittringsintensiteter för avlagringen. Na/Al-baserade index som heter CIA, CIW, CPA, PIA och Index B och Sr-baserade förhållanden Ba/Sr och Rb/Sr kommer användas (Buggle et al. 2011). Syftet med studien är att se om vittring har skett vid lokalen. Och om vittring påvisas, kunna rekonstruera vid vilka djup och slutligen göra en paleoklimatisk tolkning över lokal. Na/Al-baserade index CIA, CIW, CPA, PIA och Index B visar indikationer av vittring som varit aktiv vid studerad lokal. Sr-baserade förhållanden Ba/Sr och Rb/Sr visar samma indikation men med mer dramatiska variationer. Innehållet av mobila och icke-mobila element följer även principen om att när mobila element minskar i procent så ökar dom icke-mobila elementen. Trenderna som visas är en lång tid av kallt klimat med låg vittringsintensitet som följs av en varmare och fuktigare period med högre vittringsintensitet. Utvecklingen av denna ökande vittringsintensitet indikerar en pågående interglacial/interstadial period. Fortsättningsvis sker en minskning i vittringsintensitet vilket påvisar en början av en kallare period. Det översta lagret i lokalen har bevisats blivit förändrat av mänsklig aktivitet och kan var missvisande i en geokemisk analys och paleoklimatologisk tolkning.

Under favourable conditions, the child in the senior primary phase (from Grade 5 to Grade 7) should lead a happy and carefree life with few real problems for himlherself or his parents. At this time the child is at his/her most receptive stage, therefore it is very important that the child should acquire good study habits, study attitudes and study methods. Attitude plays a very important role in learning. If the child has a negative attitude towards study, his academic achievement will not be as desired. The child who has a negative attitude also has a negative or poor self esteem. It is important to lead the child in the senior primary phase to develop and adopt a positive attitude and self esteem. The aim for this study is to determine whether the pupils (learners) in the senior primary phase will develop a positive disposition towards learning if they are given guidance. The characteristics of the senior primary child in relation with his physical, social, emotional, moral and personal development is closely scrutenised. The focus is on study attitude and the factors that would influence it such as language, stress, self esteem, hereditary, abilities and environment. Thus the study guidance program for the child in the senior primary phase with a negative study attitude has been set out comprehensively. The focus fell upon study guidelines for study guidance in the form of group guidance and the ten sessions into which the study guidance program was set out. The study guidance program consisted of orientation of the group, aims or objectives, study attitude, self esteem, study habits, study methods, facors which influence learning, facets of the memory, attention and concentration, compiling a works program and study roster, motivation, listening, effective reading, memory aids, memorising, summarising, underlining and preparation and writing of the examination. During the empirical investigation the following steps were followed: • The school guidance teacher selected fifteen pupils (learners) from the senior primary phase (grade 6) who showed a negative study attitude. • Questionnaires about study habits, study attitudes and study methods were completed by the group before and after the study guidance program. The pupils also had to write a General Science test before and after the study guidance. The results of the General Science Tests before and after the study guidance, were compared with each other. The presentation and interpretation of the response of the questionnaire about study methods, study attitudes and study habits regarding the General Science test marks were recorded. The test marks before and after were compared. Furthermore, from the examination it came to light that the questions in the questionnaire showed a marked changed namely a great effect (0,8) except in questions 41, 46 and 49 which showed a medium effect. This improvement or change in the Science Test marks are thus educationally viable. As a result of the positive change in the questionnaire's response and the General Science test marks, it appears that the program was successful. It also shows that a study guidance program can play an important role in cases where the Senior Primary pupil (learner) has a negative study attitude. There is a definite yearning by the child in the senor primary phase to be guided during learning and thus being influenced positively. Guidance implies assistance, Le. during learning/study the child must be assisted so that learning can be effective and the potential of the child be optimally unfolded or developed. If the child's potential is optimally developed, the child will become a happy adult who will be an asset to him/herself and to the community.

Interest in the optical characteristics and variability of the sea has grown for nearly two centuries. Most of the early work in this area was performed by European investigators. Perhaps the earliest reference to an optical oceanographic research cruise can be found in the book by Otto Krümmel (1886), in which the author refers to the Rurik circumnavigational cruise of 1817 made by Otto von Kotzebue. In these studies von Kotzebue made measurements using optical instrumentation comprised of a piece of red cloth tethered to a line and lowered into the sea. With this technique, von Kotzebue was able to crudely measure the depth of penetration of light. This technique was refined by using a white plate, and the first measurements in the Pacific (at 10°N 152°W) yielded measurements of 49 meters. It is worth noting that this work was done several decades before the famous efforts of Secchi (1866). Efforts to incorporate photographic techniques to characterize the underwater light field were also developing in the late 1800’s. In March, 1885 some experiments were made in the waters off Nice, France, in which a photographic plate was submerged to depths of several hundred meters. Additional historical information can be found in the classical textbook by Sauberer and Ruttner (1941). Theoretical treatments of optical oceanography developed somewhat later. Ludvig Valentin Lorenz published the first works on the theoretical aspects of marine light scattering. This work, originally published in Danish (Lorenz, 1890), was subsequently translated into French in 1915. Martin Knudsen (founder of International Council for the Exploration of the Sea, and developer of some of the fundamental concepts for making hydrographic calculations) also had concerns about marine optics as reflected in correspondence he sent to Professor Otto Pettersson (father of Hans Pettersson) in Sweden: . . . In studying those provinces of water and particularly of sea water, which are of importance to the organisms living therein, the study of the light contents of the water must occupy the prominent place. Light contents play in many respects a similar part to that of oxygen content but have not been so strongly investigated as the latter. . . .

Ultraviolet solar radiation was measured and recorded on a 5-minute, hourly and daily basis at four sites on the Caribbean island of Puerto Rico (located from 18° to 18° 30’N latitude and from 65° 30’ to 67° 15’W longitude) over a 24 calendar month time frame. Data were measured by an Eppley Total Ultraviolet Radiometer (TUVR) mounted on a horizontal surface (0.285 ≤ λ ≤ 0.385 μm wavelengths). This data presents the first published data on ultraviolet radiation over Puerto Rico. The data sheds new light on the ultraviolet radiation characteristics of this tropical island. Characteristics such as the daily average, monthly average hourly, monthly average daily, and annual average daily ultraviolet radiation are presented. The ratio of the monthly average daily ultraviolet radiation to the monthly average daily global radiation varied between 0.0476 and 0.0498, with a mean value of 0.0487 ± 0.0009. A regression correlation between ultraviolet and global radiation on an hourly basis is also developed.

Solar radiation was measured and recorded on a 5-minute, hourly and daily basis at a number of sites on the Caribbean island of Puerto Rico (located from 18° to 18° 30’N latitude and from 65° 30’ to 67° 15’W longitude) over a 24 calendar month time frame. The global solar radiation was measured at four sites (namely: Aguadilla, Ponce, Gurabo, and San Juan). The global solar radiation data was measured by an Eppley Precision Spectral Pyranometer (model PSP) mounted on a horizontal surface. This pyranometer is sensitive to solar radiation in the range of 0.285 ≤ λ ≤ 2.8 μm wavelengths. Statistical analysis such as the daily average, monthly average hourly, monthly average daily, and annual average daily global radiation are presented in this paper. Despite its small size, a 13 percent variation in the global solar radiation has been observed within the island. Reasonable solar radiation values, for solar energy conversion system installation, seem to exist at and possibly around Aguadilla.

The increasing advance of the new technologies applied in the retail market, make it common to sell products without the personal contact between seller and buyer, being the registration and payment of the products made in electronic equipment of self-checkout. The large-scale use of these devices forces the consumer to participate in the service process, which was previously done through interaction with the company's employees. The user of the self-checkout system thus performs all the steps of the purchase, from weighing the products, registering them and making the payment. This is seen as a partial employee, whose participation or performance in providing services can be used by the company to improve the quality of its operations (KELLEY, et al 1993). However this participation does not always satisfy the user, and may cause negative experiences related to usability failures. This article presents the results of the evaluation by the users of the self-checkout system. The data were collected in Portugal through a questionnaire to 400 users. The study analyzes the degree of satisfaction regarding the quality and usability of the system, the degree of motivation for its adoption, as well as the profile of the users. Analysis of the sample data reveals that users have basic or higher education and use new technologies very often. They also have a high domain of the system and an easy learning of its use. The reason for using self-checkout instead of the traditional checkout is mainly due to "queues at checkout with operator" and "at the small volume of products". In general, the sample reveals a high degree of satisfaction with the service and with quality, however, in comparative terms, self-checkout is not considered better than operator checkout. The evaluation of the interaction with the self-checkout was classified according to twenty-six attributes of the system. The analysis identifies five groups with similar characteristics, of which two have low scores. "Cancellation of registered articles", "search for articles without a bar code", "manual registration", "bagging area", "error messages", "weight sensor" and “invoice request "are seven critical attributes of the system. The results indicate that the usability analysis oriented to the self-checkout service can be determinant for the user-system interaction. The implications of empirical findings are discussed together with guidelines for future research.Keywords: Interaction Design, Self service, Self-checkout, User evaluation, UsabilityReferencias ABRAHÃO, J., et al (2013).

RESUMO A abordagem sistêmica é um processo interdisciplinar, cujo princípio primordial é compreender a interdependência recíproca e relações de todas as áreas e da necessidade de sua integração, permitindo maior aproximação entre os seus limites de estudo. Nesse contexto o olhar sistêmico, da ergonomia, sobretudo no que se refere à segurança, ao conforto e à eficácia de uso, de funcionalidade e de operacionalidade dos objetos, considerando todos os produtos ou sistemas de produtos, como sistema de uso, desde os mais simples aos mais complexos ou sistêmicos, tem como objetivo adequá-los aos seres humanos, tendo em vista as atividades e tarefas exercidas por eles. No que se refere ao design funcional, os conhecimentos da ergonomia, nessa visão sistêmica, relativos à sua metodologia de projeto, são absolutamente necessários, e a sua aplicação aponta a melhor adequação dos produtos aos seus usuários. Como é o caso do vestuário feminino funcional, sobretudo no que se refere a proteção das mamas, que são peças convencionais que necessitam de um correto dimensionamento e especificação dos tecidos e de outros materiais. É um tipo de vestuário que apresenta funcionalidade diversa, como para a proteção física, o aumento do volume da mama, enchimento no bojo de pano, de água, de óleo, estruturado com arame, etc.; para amamentação (sutiã que se abre na frente, em parte ou totalmente); para o design inclusivo (pessoas com deficiência e mobilidade reduzida, no caso de mamas com prótese ou órtese) facilitando com fechamentos e aberturas colocadas em peças de roupas difíceis de manusear, roupas confortáveis e fáceis de vestir. São peças usadas por pessoas com biótipos e percentis antropométricos variáveis e com características corporais que mudam significativamente nas passagens para a adolescência, idade adulta e idosa. As mudanças corporais apresentam diferenças significativas em termos de volume das mamas, nas quais as soluções ergonômicas por uma abordagem sistêmicas que se evidencia mais para a complexidade de uso, são as mais necessárias em termos de atributos como, segurança, conforto, comodidade corporal, facilidade do vestir, funcionalidade, além da estética. Esta pesquisa, embora exploratória e descritiva, não isenta de desafios, tem por objetivo, por meio de dados e informações ergonômicas sistêmicas contribuir com o design funcional, de modo a oferecer subsídios para a confecção de roupas funcionais ou tecnologia vestível, com os atributos citados, respeitando a diversidade e inclusão das pessoas em todas as fases de sua vida, atendendo assim os princípios formais do design.
