    End user needs elicitation for a full-body exoskeleton to assist the elderly2015In: 6TH International Conference on Applied Human Factors and Ergonomics (AHFE 2015) and the  affiliated conferences / [ed] Ahram, T., Karwowski, W. and Schmorrow, D., Amsterdam: Elsevier, 2015, p. 1403-1409Conference paper (Refereed)
    Abstract [en]

    For ageing individuals, declining physical functional capacity can lead to loss of independence, decreased engagement in the community and reductions in quality of life. As such, solutions that can effectively and affordably supplement older adults’ diminishing functional capacity, and thus facilitate maintained independence and social participation over time are urgently required. The AXO-SUIT project - funded by the European Commission under the Ambient Assisted Living Joint Programme is developing assistive exoskeleton devices for older adults with impaired mobility and/or difficulties in performingactivities of daily living. This paper will report on-going research which aims to identify end user needs, and thus provide inputs to specify the design requirements of the AXO-SUIT exoskeletons. The objectives of this initial questionnaire study are to identify the functional assistance requirements of potential end users of the AXO-SUIT in terms of mobility, reaching and handling, and full-body support for performing activities of daily livingat home and in the wider community. The end user requirements identified will be used to formulate functional specifications for the AXO-SUIT lower-body and upper-body sub-systems, which will ensure that the AXO-SUIT prototypes will provide for the specific mobility, reaching and handling needs of end users, and also to provide useful insights into the perspectives and needs of end users in relation to assistive exoskeletons in general.

    Numerical simulation of the impact of surgeon posture on airborne particle distribution in a turbulent mixing operating theatre2016In: Building and Environment, ISSN 0360-1323, E-ISSN 1873-684X, Vol. 110, p. 140-147Article in journal (Refereed)
    Abstract [en]

    Airborne particles released from surgical team members are major sources of surgical site infections. To reduce the risk of such infections, ultraclean-zoned ventilation systems have been widely applied, as a complement to the ventilation of the main operating theatre. The function of ventilation in an operating theatre is usually determined without considering the influence of the staff members’ posture and movements. The question of whether the surgeon's posture during an on-going operation will influence particle distribution within the surgical area has not yet been explored in depth or well documented. In the present study we analysed data from investigation of two positions (bending and straightened up), which represent the most common surgeon and staff-member postures. The investigation was performed by applying the computational fluid dynamics methodology to solve the governing equations for airflow and airborne particle dispersion. Ultraclean-zoned ventilation systems were examined as an addition to the conventional operating theatre. We examined three distinct source strengths (mean value of pathogens emitted from one person per second) due to the variety of staff clothing systems. In the upright posture, the screen units reduced the mean air counts of bacteria and the mean counts of sedimenting bacteria to a standard level for infection-prone surgeries in the surgical area. However, the performance of this system could be reduced drastically by improper work experience. Surgical garments with a high protective capacity result in lower source strength and thus reduces the particle concentration within the surgical area. These results are useful for developing best practices to prevent or at least reduce the infection rate during a surgical intervention.

    Capsule purchasing practices in Chinese pharmaceutical companies: a multiple-case study analysis2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    China is now the main supplier in the generic pharmaceutical and bulk drugs supply market. The low-cost sourcing of raw materials from domestic manufacturers allows Chinese pharmaceutical companies to be competitive. Purchasing becomes strategic importance to the overall business performance through the implementation of concrete purchasing practices. This thesis is mainly to study the capsule purchasing practices in Chinese pharmaceutical companies. Three objectives are proposed in order to achieve the purpose: 1) Describe the capsule purchasing procedures of the companies; 2) Compare and analyse similarities and differences of their purchasing procedures; 3) Give acceptable reasons for these similarities and differences. These objectives are fulfilled on the basis of the developed van Weele’s purchasing procedure model and the factors integrated in purchasing. In this multiple-case study, qualitative approach is utilized in order to describe and interpret the how and why questions. The unstructured face-to face interviews are used. The study finds that the capsule purchasing strategy in Chinese pharmaceutical companies is at the stage of supply management and this may induct the raw material purchasing strategy in Chinese pharmaceutical industry.
