Magnetic resonance in patients with implanted electronic cardiac devices in light of the 2021 ESC cardiac pacing and cardiac resynchronization therapy guidelines
Authors: Świerżyńska Ewa , Sterliński Maciej
Published: February 2022

For over a decade, implantable electrotherapy devices have been available which allow — under certain conditions — diagnostic magnetic resonance imaging (MRI) tests to be performed. Detailed recommendations for the performance of these tests have been published in the latest guidelines by the European Society of Cardio­logy (ESC). The latest guidelines, compared to the 2013 recommendations, changed the recommendation class for MRI examinations. They strongly emphasised that the presence of a typical pacing system, cardioverter-defibrillator or resynchronization system, does not constitute a contraindication to MRI diagnostics. The guidelines also indicate that under certain conditions, such tests are safe and should be performed. This article pre­sents detailed recommendations of the qualifications required for an MRI and the programming devices recommended by the ESC.

Published: February 2022

Background:In this study, we aimed to evaluate the factors that contribute to survival outcomes in patients with thymoma treated with multimodal approaches.

Methods:A total of 203 patients (105 males, 98 females; median age: 49 years; range, 17 to 77 years) with Masaoka-Koga Stage II-IV thymoma between January 2002 and December 2018 were retrospectively analyzed. Data including diagnosis of myasthenia gravis, diagnosis of diabetes mellitus, disease stage, histological type of tumor, capsule invasion and surgical margin status, lymphadenectomy, adjuvant radiotherapy or chemotherapy, time from surgery to the first day of adjuvant treatment, length of hospital stay, and overall and disease-free survival rates were recorded.

Results:Of the patients, 91 had Stage II, 67 had Stage III, and 45 had Stage IV disease. A total of 123 patients (61%) had myasthenia gravis. Seventy-six patients received adjuvant radiotherapy and 48 patients received either neoadjuvant (n=35) or adjuvant (n=25) chemotherapy. Higher disease stage, presence of R1 resection, and treatment with chemotherapy were significant factors for decreased disease-free survival time. Older age, higher disease stage, longer postoperative hospital stay, chemotherapy, and disease recurrence were effective contributors to decreased overall survival time. Adjuvant radiotherapy had a statistically significant positive effect on overall survival only in patients with completely resected Stage IV disease (five-year overall survival: 94.7% vs. 79.1%, respectively; p=0.015). In the multivariate analysis, older age (hazard ratio: 4.26), higher disease stage (hazard ratio: 2.95), and longer hospitalization time (hazard ratio: 3.81) were significant prognostic factors for overall survival. Patients with local recurrence who underwent complete resection had a survival time comparable to non-recurrent patients (p=0.753).

Conclusion:For patients with thymoma, higher disease stage, age ?50 years, longer hospitalization, and need for chemotherapy are associated with worse survival rates. Adjuvant chemotherapy has a positive impact on Stage IV disease. Resection of recurrent lesions has a valuable impact on survival.

Authors: Azizoğlu Mustafa , Yapıcı Davud , Bayülgen Abdülkerim , Sagün Aslınur , Özdemir Levent , Rumeli Şebnem
Published: February 2022

Background: The aim of this study was to evaluate the effect of serratus anterior plane block in addition to intrathecal morphine for early postoperative period after video-assisted thoracoscopic surgery on the amount of morphine consumption and the Visual Analog Scale scores.

Methods: This single-blind, randomized-controlled study included a total of 64 patients (39 males, 25 females; mean age: 53.6±17.0 years; range, 20 to 89 years) who were scheduled for video-assisted thoracoscopic surgery in a tertiary hospital between September 2019 and March 2020. Postoperative pain control was achieved with intrathecal morphine 0.6 mg addition to serratus anterior plane block (Group ITM+SAPB) or with only intrathecal morphine (Group ITM) after an induction of anesthesia. The serratus anterior plane block was performed with a single injection of 0.4 mL/kg of 0.25% bupivacaine at the level of fifth rib with ultrasound guidance. Morphine consumption, pain scores, and side effects were recorded in the postoperative period.

Results: The mean morphine consumption was significantly lower in the ITM+SAPB group at all time points. Compared to the control group, the Visual Analog Scale-resting and coughing scores were significantly lower in the first 12 h after surgery. Pain scores were significantly higher in the ITM+SAPB group in patients where the trocar was inserted at upper level of the fifth rib than the lower level (3-5 vs. 5-8) during the first 6 h after surgery.

Conclusion: The use of serratus anterior plane block in addition to intrathecal morphine is a safe and effective way to improve pain control for early postoperative period after video-assisted thoracoscopic surgery. The serratus anterior plane block ensures better analgesia until the peak effect of spinal morphine occurs.

Authors: Altın Önder , Kaya Selçuk , Sarı Ramazan
Published: February 2022

Background: In this study, we aimed to compare multiple versus single incision laparoscopic repair of Morgagni hernia in adults and to investigate effectiveness and feasibility of both techniques.

Methods: Between January 2011 and March 2018, a total of 15 patients (5 males, 10 females; median age: 58.6 years; range, 36 to 70 years) who underwent laparoscopic or single-incision laparoscopic repair of Morgagni hernia were retrospectively analyzed. Demographic and clinical characteristics of patients, perioperative data, and treatment outcomes were evaluated.

Results: The median follow-up was 38 (range, 11 to 84) months. Of the patients with Morgagni hernia, 12 were treated with laparoscopic and three were treated with single incision laparoscopic repair technique. Patient satisfaction was excellent for most of the patients in both groups. No recurrence was observed during follow-up.

Conclusion: Morgagni hernia is a very rare type of hernia in adults. Laparoscopic mesh-reinforced primary repair of Morgagni hernia should be one of the first choice in patients, particularly with large hernias that would cause tension on edges of the diaphragm when closed. Single incision laparoscopic repair of Morgagni hernia is also another laparoscopic option with high patient satisfaction.

Background: In this study, we aimed to evaluate early and longterm outcomes of both isolated or concomitant coronary artery bypass grafting with the endoscopic vein harvesting technique.

Methods: Between November 2012 and May 2017, a total of 324 patients (259 males, 65 females; mean age: 63.2±9.8 years; range, 36 to 91 years) who underwent coronary artery bypass grafting, with or without concomitant procedures, using the endoscopic vein harvesting technique were retrospectively analyzed. Early postoperative outcomes and long-term follow-up data of the patients, such as cardiovascular or cerebral events, cardiac reinterventions, and the images of coronary angiography were recorded.

Results: Median logistic EuroSCORE and in hospital mortality was 3.99 (0.8-81) vs. 0 .9% f or i solated c oronary surgery and 13.34 (1.5-76.4) vs. 1.5% for concomitant procedures. The long-term data could be obtained in 288 patients with a median of 59.6 (7-90) months of follow-up. During this period, 22 (7.6%) patients underwent coronary angiography for control or treatment, 12 (4.2%) patients needed revascularization, and none of the patients underwent redo coronary surgery.

Conclusion: Our study results suggest that the endoscopic vein harvesting technique during coronary artery bypass grafting is safe in experienced hands.
Effect of stent graft fixation types on pararenal aortic diameter and renal function after endovascular aortic repair
Authors: Sangtae Choi , Wonsuk Lee , Jinmo Kang , Doojin Kim , Daisik Ko
Published: February 2022

Background: This study aims to identify pararenal aortic diameter changes following endovascular aortic repair and to investigate the effects of suprarenal fixation on renal function.

Methods: Between May 2006 and January 2019, a total of 168 patients (135 males, 33 females; mean age: 75.2±8.4 years; range, 48 to 93 years) who underwent endovascular aortic repair were retrospectively analyzed. To compare the effects of graft types, we measured the change in pararenal aortic diameter at four levels: below the celiac artery, below the superior mesenteric artery, at the lowest renal artery, and 1 cm below the lowest renal artery. To evaluate the effect of suprarenal fixation on renal function, serial measurements of serum creatinine, glomerular filtration rate, creatinine clearance rate, and estimated glomerular filtration rate were made. We examined the factors related to post-procedural aortic diameter.

Results: The mean change in the aortic diameter was statistically significant, being 12.9±10% in the suprarenal fixation group and 6.19±6.9% in the infrarenal fixation group only at the lowest renal artery level (p=0.001). There was no significant difference in the rate of type I endoleak (p=0.330) or renal function and adverse events (p>0.107) between the groups. The formula for calculating post-procedural aortic diameter was as follows: post-procedural aortic diameter (renal artery level, mm) =1.845 (in case of suprarenal fixation) + 1.012 × pre-procedural aortic diameter (renal artery level, mm) + 0.029 × follow-up time (months) + 0.039 × oversizing (%) (R2=0.773, p<0.001).

Conclusion: Suprarenal fixation affects the infrarenal aortic diameter at the lowest renal artery level without significant type I endoleak. However, it does not result in significant renal dysfunction. Pre-procedural aortic diameter, computed tomography follow-up time, suprarenal fixation type, and stent oversizing are the only definite independent correlation factors for postprocedural aortic diameter. This formula can predict the change of aortic diameter after endovascular aortic repair.

Background and Purpose There are reports of decline in the rates of acute emergency presentations during coronavirus disease 2019 (COVID-19) pandemic including stroke. We performed a meta-analysis of the impact of COVID-19 pandemic on rates of stroke presentations and on rates of reperfusion therapy.Methods Following the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines, we systematically searched the literature for studies reporting changes in stroke presentations and treatment rates before and during the COVID-19 pandemic. Aggregated data were pooled using meta-analysis with random-effect models.Results We identified 37 observational studies (n=375,657). Pooled analysis showed decline in rates of all strokes (26.0%; 95% confidence interval [CI], 22.4 to 29.7) and its subtypes; ischemic (25.3%; 95% CI, 21.0 to 30.0), hemorrhagic (27.6%; 95% CI, 20.4 to 35.5), transient ischemic attacks (41.9%; 95% CI, 34.8 to 49.3), and stroke mimics (45.6%; 95% CI, 33.5 to 58.0) during months of pandemic compared with the pre-pandemic period. The decline was most evident for mild symptoms (40% mild vs. 25%–29% moderate/severe). Although rates of intravenous thrombolytic (IVT) and endovascular thrombectomy (EVT) decreased during pandemic, the likelihood of being treated with IVT and EVT did not differ between the two periods, both in primary and in comprehensive stroke centers (odds ratio [OR], 1.08; 95% CI, 0.94 to 1.24 and OR, 0.95; 95% CI, 0.83 to 1.09, respectively).Conclusions Rates of all strokes types decreased significantly during pandemic. It is of paramount importance that general population should be educated to seek medical care immediately for stroke-like symptoms during COVID-19 pandemic. Whether delay in initiation of secondary prevention would affect eventual stroke outcomes in the long run needs further study.
The Challenge of Designing Stroke Trials That Change Practice: MCID vs. Sample Size and Pragmatism
Authors: Goyal Mayank , McDonough Rosalie , Fisher Marc , Ospel Johanna
Published: February 2022

Randomized controlled trials (RCT) are the basis for evidence-based acute stroke care. For an RCT to change practice, its results have to be statistically significant and clinically meaningful. While methods to assess statistical significance are standardized and widely agreed upon, there is no clear consensus on how to assess clinical significance. Researchers often refer to the minimal clinically important difference (MCID) when describing the smallest change in outcomes that is considered meaningful to patients and leads to a change in patient management. It is widely accepted that a treatment should only be adopted when its effect on outcome is equal to or larger than the MCID. There are however situations in which it is reasonable to decide against adopting a treatment, even when its beneficial effect matches or exceeds the MCID, for example when it is resource- intensive and associated with high costs. Furthermore, while the MCID represents an important concept in this regard, defining it for an individual trial is difficult as it is highly context specific. In the following, we use hypothetical stroke trial examples to review the challenges related to MCID, sample size and pragmatic considerations that researchers face in acute stroke trials, and propose a framework for designing meaningful stroke trials that have the potential to change clinical practice.
Hypertriglyceridemia: A Neglected Risk Factor for Ischemic Stroke?
Authors: Liang Hai-jie , Zhang Qing-yi , Hu Yi-tong , Liu Guo-qing , Qi Rong
Published: February 2022

Hypertriglyceridemia is caused by defects in triglyceride metabolism and generally manifests as abnormally high plasma triglyceride levels. Although the role of hypertriglyceridemia may not draw as much attention as that of plasma cholesterol in stroke, plasma triglycerides, especially nonfasting triglycerides, are thought to be correlated with the risk of ischemic stroke. Hypertriglyceridemia may increase the risk of ischemic stroke by promoting atherosclerosis and thrombosis and increasing blood viscosity. Moreover, hypertriglyceridemia may have some protective effects in patients who have already suffered a stroke via unclear mechanisms. Therefore, further studies are needed to elucidate the role of hypertriglyceridemia in the development and prognosis of ischemic stroke.

Published: February 2022

Mechanical thrombectomy (MT) is the most effective treatment for selected patients with an acute ischemic stroke due to emergent large vessel occlusions (LVOs). There is an urgent need to identify and address challenges in access to MT to maximize the numbers of patients who can benefit from this treatment. Barriers in access to MT include delays in evaluation and accurate diagnosis of LVO leading to inappropriate triage, logistical delays related to availability of facilities and trained interventionalists, and financial hurdles that affect treatment reimbursement. Collection of regional data related to these barriers is critical to better understand current access gaps and a measurable access score to thrombectomy could be useful to plan local public health intervention.
Research on Design Optimization of High-Speed Ship Bulbous Bow Based on Nelder-Mead Algorithm
Authors: Jie Liu , Bao-Ji Zhang , Ning Xu
Published: February 2022

In order to reduce the wave-making resistance of ships, this paper proposes an optimization design method for bulbous bow form based on potential flow theory. In this paper, we restrict our interest to parametric deformation of the bow, at the same time constrain the displacement and the length of the ship. Based on Rankine source method, the wave-making resistances of DTMB5512 and ITTC Ship A-2 are calculated. For optimization, Sobol algorithm is selected to create sample space; based on it, we use Nelder–Mead algorithm to obtain the optimal hull form in the space. Additionally, we compare and analyze the hydrodynamic performance of the ship. The results show that the optimization design method reduces the wave-making resistance of DTMB5512 and ITTC Ship A-2, which verifies the feasibility of the method.

Introduction

Energy Efficiency Design Index (EEDI) guides the future development of the shipbuilding industry toward green ships and accelerates the pace of energy conservation and emission reduction. EEDI is closely related to hull form; therefore, the design optimization of ship hull focus on reducing EEDI becomes the central issue of the current research (Hou et al. 2018).

O biossólido de curtume apresenta-se como uma alternativa viável para os plantios florestais, entretanto, pode apresentar composição química variada e concentrações elevadas de cromo e sais minerais, como o sódio. Objetivou-se avaliar o aspecto nutricional, o crescimento e o acúmulo de massa seca de plantas de Eucalyptus pellita em diferentes doses de biossólido de curtume. O experimento foi realizado em casa de vegetação com delineamento inteiramente casualizado e cinco repetições (5 x 5). Os tratamentos foram compostos por quatro doses do biossólido de curtume (24, 40, 75 e 100 t ha-1) e um controle (adubação inorgânica). A dose de 100 t ha-1 aumentou a massa seca da raiz, folha e caule em 70,52, 18,18 e 42,25% respectivamente, em comparação ao controle. A aplicação de adubação complementar é necessária para atender as exigências nutricionais da planta. O Índice de Qualidade Dickson (IQD) mostrou ganhos de qualidade das plantas com as doses crescentes de biossólido. A concentração foliar de Cr estava abaixo do nível considerado tóxico para as plantas de eucalipto. O Ca e Mg apresentaram concentrações dentro da faixa considerada ideal. O uso do biossólido de curtume é uma opção para o fornecimento de nutrientes em plantios de eucalipto.

A simbiose entre plantas fitorremediadoras e microrganismos com atividade enzimática metabolizadora de herbicidas pode ser uma alternativa eficiente para remediação de solos contaminados com sulfentrazone. Objetivou-se avaliar a Crotalaria juncea (crotalária) inoculada com Bradyrhizobium sp. na fitorremediação do sulfentrazone e seus efeitos na biomassa microbiana do solo. O experimento foi conduzido em casa-de-vegetação da Universidade Federal do Espírito Santo (UFES), testando-se quatro doses de sulfentrazone (0, 400, 800 e 1200 g i.a. ha-1) na presença ou ausência da inoculação com Bradyrhizobium sp. BR2003 (SEMIA 6156). Após 65 dias de cultivo, as plantas foram cortadas, o solo foi coletado para as análises da biomassa microbiana e o bioensaio com o milheto. A inoculação com Bradyrhizobium sp. proporcionou melhor desenvolvimento em altura das plantas de crotalária, entretanto, o sistema radicular não foi influenciado pela adição do microrganismo. Os indicadores biológicos do solo mostraram que a inoculação com Bradyrhizobium sp. influenciou de maneira negativa na atividade microbiana dos solo. A crotalária apresentou boa tolerância aos níveis de sulfentrazone no solo, independentemente do inoculante. Os resultados sugerem que a inoculação da crotalária com Bradyrhizobium sp. não mostrou benefício na eficácia da remediação dos sulfentrazone, tendo a crotalaria melhor desempenho com os microrganismos nativos do solo.

No Brasil, ela é geralmente cultivada pela agricultura familiar, mas em grande parte surge de maneira espontânea e os frutos são colhidos e consumidos. O Nordeste é a região que mais produz e consome o fruto, tornou-se cultural nessa região as famosas “maxixadas”. Diante disso, objetivou- se com este trabalho avaliar o desempenho do maxixeiro submetido à inoculação de microrganismos promotores de crescimento. O experimento foi desenvolvido na Universidade Federal Rural da Amazônica campus Belém. Os tratamentos foram submetidos a duas bactérias (R96 e R46) e ao fungo Trichoderma. O delineamento experimental utilizado foi inteiramente casualizado (DIC), com oito tratamentos e quatro repetições. Foram realizadas análises biométricas (comprimento da haste, número de folhas, diâmetro do caule), de quantidade e peso dos frutos e fisiológicas (condutância estomática – COnd, taxa de assimilação de CO2 – PHOTO, transpiração – Trmol e temperatura da folha – TLEAF). Após 90 dias, o material foi pesado para obtenção de dados de massa úmida (MU). Após a secagem em estufa por 72h, foi feito uma segunda pesagem para obter os dados de massa seca (MS). Os dados obtidos foram submetidos à análise de variância e teste de Tukey a 5% de probabilidade e análise multivariada. Verificou-se que os microrganismos promotores de crescimento em plantas (MPCP) não influenciarem a produção de frutos, flores e folhas da cultura do maxixe.

Lixiviado de aterro sanitário é um dos subprodutos da decomposição biológica dos resíduos sólidos urbanos, sendo gerado no interior das células do aterro. Sua composição química está diretamente relacionada a idade a as características dos resíduos sólidos nele dispostos. Lixiviados mais velhos apresentam alto potencial poluidor, devido a presença de alta concentração de material orgânico de difícil biodegradação, macro poluentes inorgânicos, metais pesados e compostos orgânicos xenobióticos, sendo inviável o tratamento biológico. O presente trabalho teve como objetivo avaliar a eficiência do processo Fenton no tratamento de lixiviado proveniente do aterro sanitário da município de Puxinanã-PB, para isso foi realizado a caracterização química do Lixiviado “in natura” (LIN) e do Efluente Fenton (EF), e identificação de compostos orgânicos aplicando cromatografia gasosa acoplada a espectrometria de massa (CG-EM). Analisando os resultados pode-se constatar que o processo Fenton propiciou eficiência média de remoção de DQO total de 87%, cor verdadeira de 98%, COD de 74% e DBO5 de 70%. A relação DBO5/DQO total no EF aumentou em um percentual de 100%, quando comparado ao LIN. O processo Fenton removeu 80% dos compostos orgânicos identificados no LIN, dos 29 compostos que permaneceram no EF, alguns são reconhecidamente tóxicos como o cloro benzeno, bisfenol A, etil-benzeno e o 1-etil-2-metil-Benzeno. Foi constatada, ainda, a formação de 50 novos compostos orgânicos como subprodutos da oxidação de compostos químicos no processo Fenton.

Untersuchungen in Hagestad, Schonen In Hagestad im südöstlichen Schonen findet seit 1960 eine Untersuchung statt mit dem Ziel, Klarheit über die Siedlungsgeschichte während der ganzen Vorzeit zu bekommen, sowie auch einen Ausgangspunkt für die Behandlung von einer Reihe von Problemen zu erhalten, die teils diesen Teil von Schonen angehen, teils von mehr allgemeiner Bedeutung sind. Die Arbeit wurde zurechtgelegt als »team work«, an dem Forscher verschiedener Disziplinen teilnehmen. Der Archäologe arbeitet zusammen mit einem Kulturgeographen, einem Geologen, einem Botaniker, einem Zoologen und einem Sprachwissenschaftler, und außerdem nimmt man andere Spezialisten für verschiedenerlei Arbeit in Anspruch. Das bisher erhaltene Material ist von sehr großem Umfang, und die Ausgrabungen in Hagestad haben Untersuchungen an anderen Orten im östlichen und südöstlichen Schonen veranlalß, die Licht über die gleichen Probierne werfen.Eine wichtige Frage in diesem Zusammenhang ist, auf welche Weise man sich Eisen verschaffte, und wie das Schmieden in verschiedenen Abschnitten der Vorgeschichte vor sich gegangen ist. In Hagestad und angrenzenden Kirchspielen ist wesentliches Material zur Beleuchtung dieser Frage gefunden worden. An mehreren Orten hat man Anlagen gefunden, die deutlich belegen, daß Arbeit mit Eisen stattgefunden hat, und zwar teils das Ausbrennen von Erz, eventuell auch eine zweite Reduktion von Erz, das schon den ersten Prozess hinter sich hatte, teils das Ausschmieden von größeren oder kleineren Gegenständen. Die Feldarbeit ist jedoch noch nicht abgeschlossen, und darum dürfte man erwarten, weiterhin noch einiges Material dieser Art zu finden. Märta Strömberg
Hvolris. Et neolitisk kompleks
Authors: Seeberg Peter
Published: February 2022

Hvolris I Ein neolithischer Komplex.Das ausgegrabene Material der Örtlichkeit Hvolris, Kirchspiel Hersom, Kreis Viborg, befindet sich im Besitz von Viborg Stiftsmuseum. In den Jahren 1962-66 hat das Museum hier teils eine Reihe von Hausresten aus der älteren Eisenzeit abgedeckt, teils einen Komplex von Steinschichten und kleineren Anlagen (Gruben, Pfostenlöcher, Vertiefungen), die der mittelneolithischen Zeit angehøren.Die Untersuchung hat sich auf die Vermutung stützen müssen, daß der gesamte neolithische Komplex mit dem dazugehörenden Scherbenmaterial von seiner ursprünglichen Lage auf einer Waldhumusschicht durch die Aktivität von Regenwürmern auf das Untergrundniveau gesenkt worden ist.Daß das Material aus späteren Zeitabschnitten nur in geringem Maße auf das Untergrundniveau gebracht worden ist, verdanken wir wahrscheinlich dem Umstand, daß die biologische Aktivität durch Holzschlag und Austrocknen verringert worden ist. Die gefährliche Möglichkeit einer Änderung der stratigraphischen Grundbedingungen ist so vermieden worden, soweit außerdem, daß die beiden Kulturhorizonte überall durch eine scherbenlose Waldhumusschicht voneinander getrennt sind.Die Untersuchung hat das Vorkommen von zwei keramischen Traditionen im neolithischen Material nachgewiesen. Eine feinkörnige Ware beherrscht den eigentlichen Komplex und gehört in die Mittelphasen der Einzelgrabkultur, während eine grobere Ware in einem Gebiet nordöstlich von dem Komplex konzentriert ist. Diese Keramik gehört der älteren Ganggrabzeit an.Die Darstellung dieser Untersuchung ist ein Versuch der reinen Beschreibung eines Objektes, registriert in seiner faktischen Lage innerhalb der Stratigraphie einer gegebenen Örtlichkeit. Die fortgesetzten Untersuchungen in Hvolris machen es sich zur Aufgabe, andere faktische Einzelheiten miteinander zu verbinden und so ein eventuelles Kulturbild von lokal begrenztem Umfang zu erhalten.Peter Seeberg

Da demokratiet gjorde vore forfædre vilde – og de vilde til sig selv
Authors: Høiris Ole
Published: February 2022

When democracy turned our forefathers into savages – and the savages into themselvesIn Denmark, there are two major ethno­graphical collections, both of which have served as stud y collections for Danish archaeologists in certain periods. The idea was that our ancestors lived by and large like contemporary primitive peoples, an idea anthropologists strongly repudiate today with reference to the dignity of other peoples, just as pre-historians did 200 years ago with refer­ ence to the dignity of the Danish people. In this article, I demonstrate how the establishment of a national popular democracy in the 19th century changed national history – which was a central factor in the production of Danish identity – from the history of the kings to the history of the people. This in turn made the evolutionary theories of the socia l philosophers of th e Enli ghtenment relevant, creatin g the idea that the lives of contemporary savages were more or less the same as the lives of our  ancient ancestors. This then made the ethnographical collections relevant for archaeological studies.To­day anthropologis ts are very negative toward such evolutionary ideas, and it is demonstrated how it was the extension of democracy to an int ernational level that changed the conception of other peoples from remnants of the past to contemporary but culturally different peoples. The possibilities or impossibilities of close cooperation between archaeology and anthropology have thus alternat ed cyclically during the past 200 years, and if you formulate the problem as one of the relation beween theories of cultural differences and theories of human development you can prolong this oscillation between close cooperation and total separation at least 2500 years. So sometime in the future an thropology and archaeolo gy will cooperate closely again.Ole HøirisCenter for Kulturstudier Aarhus Universitet
Maritim læring i vikingetiden – Om praksisfællesskabets marginale deltagere
Authors: Ravn Morten
Published: February 2022

The acquisition of maritime skills in the Viking AgeThe acquisition of maritime skills in the Viking Age can be examined through application of the social constructivist theory with respect to communities of practice. A community of practice is maintained via skill transfer. The process begins already in childhood and leads to the gradual inclusion of these marginal participants as fully valid members. By way of their role play and rule games, based in part on observations of adult practice, children acquire basic skills and develop a knowledge of the community’s sensus communis.The aim of this article is not to describe the players in the community of practice, i.e. the children and adults of the Viking Age, but to examine the relationship between them in a practice structure. The child and the adult are perceived as mutual preconditions. They are, seen in relation to a common practice, parts of the same community. It is the learning process, from marginal participant via legitimate peripheral participant to fully valid member, which defines and maintains this community of practice.Model ships which can be dated to the Viking Age have been found in several locations across Northern Europe (fig. 1). These are employed in this article to examine the skill-transfer processes inherent in Viking Age communities of practice. Some of the model ships can be interpreted as children’s toys and are very detailed in their execution, with holes for a mast, a side rudder and oars (fig. 2). Other miniature artefacts, such as anchors and weather vanes, can similarly be argued to have comprised part of the fittings of these toy ships.In order to gain a more detailed insight into the process of skill acquisition in maritime communities of practice, a selection of sailors’ memories from their childhood in the Danish maritime town of Marstal  in the late 19th and early 20th century are drawn upon (fig. 3). This is exclusively to demonstrate how children learn through play.The model ships and their equipment, if these are interpreted as children’s toys, give access to an aspect of Viking Age society which is very difficult to study in other ways. The toy ships are a material expression of the play which – then as now – has equipped children for their passage into the community of practice. It is this play which, in spite of its superficially banal character, is fundamental to the maintenance and development of a community of practice.Morten RavnAfdeling for Forhistorisk ArkæologiSaxo-InstituttetKøbenhavns Universitet
