Teamwork involves different types of interactions—specifically cooperation andcollaboration—that are necessary in education and many other professions. The differencesbetween cooperation and collaboration underline the teacher’s role in influencing groupdynamics, which represent both a foundation for professional design education and aprequalification for students’ competences as teachers and for critical evaluation. As a testcase, we focused on the Working Together action-research project in design education forspecialised teacher training in design, arts, and crafts at the Oslo Metropolitan University,which included three student groups in the material areas of drawing, ceramics, and textiles.The project developed the participants’ patience, manual skills, creativity, and abilities,which are important personal qualities for design education and innovation and representcornerstones in almost every design literacy and business environment. The hope is thatstudents will transform these competences to teaching pupils of all ages in their futurecareers.

In pre-modern Korea, paper was renowned for its white glossy surface and cloth-like strength, becoming an important item in both tributary exchanges and private trade. The unique material of the tak tree and related technical innovations, including toch’im, the repeated beating of just-produced paper that provides sizing and fulling effects, were crucial to this fame. However, the scholar-officials who integrated papermaking into the state production system in order to meet administrative and tributary needs initially made toch’im corvée and then penal labor, thereby dismissing it as simple toil. They were not alone, though, in denigrating a form of manual labor. Historiographies of modern science and technology are generally silent about such work, focusing instead on how we invented the human out of drudgery. However, papermakers in late Chosŏn Korea (the eighteenth and nineteenth centuries) chose to identify their artisanship with toch’im and eventually succeeded in securing recognition for that technique as a highly paid specialty. By examining this skilling of toch’im, this paper seeks to change the historiographical silence about toil. It overcomes the archival silence that accompanies manual skills by tracing toch’im’s contours through its changing locations and associations in society’s changing social and material networks, revealing paper artisans’ social techniques, or everyday politics that eventually dignified their laborious technique. Paper artisans’ changing relationships with tak barks, tools and facilities, central and local authorities, farmers, merchants, and scholar-officials reveal how such social skilling was made in late Chosŏn Korea, where papermaking became a most successful industry. This tracing of toch’im re-situates creative toil and everyday politics of artisanal hands in the interconnected transformation of social relations, craft, and knowledge practices.

This paper introduces and validates quantitative performance measures for a rhythmic target-hitting task. These performance measures are derived from a detailed analysis of human performance during a month-long training experiment where participants learned to operate a 2-DOF haptic interface in a virtual environment to execute a manual control task. The motivation for the analysis presented in this paper is to determine measures of participant performance that capture the key skills of the task. This analysis of performance indicates that two quantitative measures—trajectory error and input frequency—capture the key skills of the target-hitting task, as the results show a strong correlation between the performance measures and the task objective of maximizing target hits. The performance trends were further explored by grouping the participants based on expertise and examining trends during training in terms of these measures. In future work, these measures will be used as inputs to a haptic guidance scheme that adjusts its control gains based on a real-time assessment of human performance of the task. Such guidance schemes will be incorporated into virtual training environments for humans to develop manual skills for domains such as surgery, physical therapy, and sports.

Samuel Phillips Bedson was born on 1 December 1886 in Newcastle upon Tyne. His father, Peter Phillips Bedson, was born in Manchester, educated at Manchester Grammar School and studied chemistry under Sir Henry Roscoe at Owens College, later Manchester University. After a period of postgraduate study at the University of Bonn, Peter Bedson returned to this country and was appointed to the Chair of Chemistry in the University of Durham (Durham College of Science, Newcastle upon Tyne). He held this Chair for 37 years until his retirement in 1921. His wife was the daughter of Samuel Hodgkinson, cotton spinner (Hollins Mill Co.) of Marple, Cheshire. There were three children of this marriage, Sam being the second. Along with his elder brother and four other boys he was educated privately until the age of ten. Then after one year at Newcastle Preparatory School he went to Abbotsholme School in Derbyshire where he spent the next six years. This school had been founded by Cecil Reddie as an experiment in secondary education because of his dissatisfaction with the narrowness of the curriculum in most Public Schools. Reddie planned ‘a programme of general education catering for physical and manual skills, for artistic and imaginative development, for literary and intellectual growth and for moral and religious training’.

AbstractThe non-destructive collection of ultrathin sections onto silicon wafers for post-embedding staining and volumetric correlative light and electron microscopy traditionally requires exquisite manual skills and is tedious and unreliable. In MagC introduced here, sample blocks are augmented with a magnetic resin enabling remote actuation and collection of hundreds of sections on wafer. MagC allowed the correlative visualization of neuroanatomical tracers within their ultrastructural volumetric electron microscopy context.

Currently, mortality rate in the liver and spleen injuries remains high, despite the present-day level of advances in the diagnosis and treatment of surgical diseases. Damage to parenchymal organs leads to the development of intra-abdominal bleeding. The severity of bleeding depends on the anatomical features of the blood supply to the damaged organ and the massiveness of the lesion, the type of traumatic agent. Intraoperative provision of reliable hemostasis is a significant problem in liver and spleen injuries. This paper summarizes the experience of Russian and foreign experts on surgical treatment of various types of parenchymal organ injuries. Stitching, adhesive compositions, biological and synthetic films, non-contact methods are used to achieve the final intraoperative hemostasis for parenchymal organ injuries; electrocoagulation is also very popular. Currently, the issues of surgical treatment tactics of spleen and liver injuries are not fully resolved. The search for optimal options, as well as technical advancement of organ-preserving operation techniques involving parenchymal organs, remains relevant. This depends on the structural features of these organs, availability of the methods of local hemostasis listed in this paper and surgeon's knowledge and manual skills. Moreover, at present, hemostatic application agents are widely introduced into clinical practice, parenchymal bleeding caused by superficial planar injuries of parenchymal organs being the main indication for the use of these agents.

The evaluation sheet was tested and practical skills for conducting puncture and catheterization of the internal jugular vein in clinical residents at the station «Catheterization of the internal jugular vein under ultrasound control» were evaluated. The manipulation was performed by 28 second-year clinical interns on the phantom, which allows the puncture of the vessel under the control of ultrasound. The evaluation of manual skills, independently of each other, was carried out by two teachers. Successfully station passed 100% of the examinees. The total time spent on the passage of one resident station was 6,3 (5,1; 7,3) minutes. In100% of cases, the residents demonstrated their knowledge of the technique of puncture and catheterization of the internal jugular vein. In 8 (28,5%) cases, the most frequent errors encountered during the passage of the station were associated with the absence of time fixation after the manipulation, in 10 (35,7%) residents the state of health was not monitored. The differences in the completed evaluation sheets of teachers amounted to 3%. It is shown that the developed evaluation sheet allows you to objectively assess the practical skills of graduates of residency. This evaluation sheet will be further used in the assessment of practical skills at the stage of primarily specialized accreditation for graduates of residency in the speciality «Anesthesiology and reanimatology».
