This study presents the mechanical properties of weft knitted sandwich fabrics (bursting strength) and the effect of the raw materials used. Two types of fabrics, with and without reinforcing yarns, were analysed. To determine the influence of the raw material type, a combination of three structure variants were obtained by changing the position in the structure architecture of two types of raw material: Kevlar® and linen yarns. Each of these variants was studied at three levels of density, given by the position of the quality cam, in order to determine the influence of this parameter. Tests were organised in two stages: the first concerned the bursting behaviour of single layer fabrics, and the second considered the study of more layers of sandwich fabrics with different orientation. Satisfactory results were obtained after this study regarding the possibility of replacing the high-performance yarns with natural ones.

ABSTRACT. INGA 3D project -Creative Transfer of Competence in 3D Footwear CAD to VET Professionals aims to transfer and extend innovative software solutions and 3D technologies for Footwear Computer Aided Design. The project brings together universities, research and training centres, adult education providers and IT companies from Romania, Spain, Portugal, and UK. The project products introduce innovative solutions for e-learning in order to test and to validate new teaching methodologies and approaches suitable for vocational training. The INGA 3D training content, its supportive guide as well as the online learning platform was designed, developed, tested and evaluated in line with the best practices identified by partners in their institutions, countries and elsewhere in Europe. INGA 3D project contributes to developing skills and competencies of VET teachers, trainers, tutors, in order to face the future challenges raised by the necessity of adding to the current curricula in VET institutions ICT skill sets that will enable their graduates to work with highly specialized footwear CAD technologies.

ABSTRACT. The article presents a method of designing templates for modelling shoe lasts, according to specific anthropometrical dimensions of a subject's foot, employed as military personnel. The subject's peculiarity lies in the type of professional activity that he is carrying out; the lower limbs have a much greater risk of injury and there is the need to prevent such problems by using special footwear, which will not restrict the conduct of his military activities. The design of last's templates consists in creating a geometrical construction based on the dimensional characteristics of the subject's feet. Using software such as Delcam Engineer and Last Maker new techniques for modelling shoe lasts were developed. The advantages of the presented method are represented by the decreased time of last's design and the accuracy of the results. Applying this method to a larger scale enables its development and allows footwear manufacturers to achieve a diverse range of products, faster and at lower costs than current possibilities. KEY WORDS: foot, military footwear, shoe last, template MODELAREA 3D A CALAPOADELOR PENTRU ÎNCÃLÞÃMINTE UTILIZÂND ªABLOANE DEFINITE PE BAZA DIMENSIUNILOR ANTROPOMETRICE ALE PICIORULUI -STUDIU DE CAZ REZUMAT. Se prezintã în cadrul acestui articol o metodã de proiectare a ºabloanelor pentru modelarea calapoadelor încãlþãmintei, corespunzãtoare dimensiunilor antropometrice ale piciorului unui subiect angajat ca personal militar. Particularitatea subiectului constã în activitatea profesionalã pe care acesta o desfãºoarã; membrele inferioare sunt supuse unui risc de accidentare mult mai mare, fiind necesarã preîntâmpinarea acestor probleme utilizând încãlþãminte specialã, care sã nu limiteze sub nicio formã desfãºurarea activitãþilor militare. Proiectarea desfãºuratei suprafeþei plantare a calapodului constã în realizarea unei construcþii geometrice ce are la bazã caracteristicile dimensionale ale picioarelor subiectului analizat. Au fost dezvoltate noi tehnici de modelare a calapoadelor folosind aplicaþiile software Delcam Engineer ºi Last Maker. Avantajele metodei prezentate în aceastã lucrare sunt reprezentate de timpul redus de execuþie ºi de corectitudinea rezultatelor. Aplicarea acestei metode la o scarã largã oferã posibilitatea dezvoltãrii acesteia ºi utilizarea ei de cãtre producãtorii din domeniul încãlþãmintei pentru realizarea unei game variate de produse mai rapid ºi cu costuri mai reduse decât posibilitãþile actuale.

Gait and balance disorders are common in older adults and they are independent predictors for the functional decline resulting in various degrees of disability and loss of independence. Gait disorders have multiple causes, they have a progressive course and may negatively impact the functional performances. Many gait disorders appear in connection with underlying diseases. The incidence of gait deficiencies is greater in older women. Non-neurological causes are more often identified. Painful joint deformities are common causes of gait disturbances in elderly. The study proposes to identify the influence of age on the walking speed and the support phase during walking. The study included 100 female volunteers, aged between 55 and 87. The subjects participated in the measurement of biomechanical parameters using AMTI's AccuGait System, while speed was determined using a speed measurement system placed above the ground reaction force measuring platform. It was found that there are statistically significant differences among the three age groups in terms of walking speed and support phase.
