The socket is the most important aspect of the artificial limb, constituting the critical interface between the amputee’s stump and prosthesis. The design and fitting of the socket is also the most difficult procedure due to the uniqueness of each amputee’s stump. An uncomfortable socket fit is the most common complaint from lower limb amputees with surveys revealing that amputees believe comfort are the most important aspects of the prosthesis and over half of all wearers are in moderate to severe pain for most of the time whilst wearing the prosthesis. Kristinsson argued that a transtibial socket can be designed to transfer loads primarily to limited areas of the limb such as the patella tendon and the medial flare, which in most cases found both ineffective and uncomfortable. There were inconsistencies in producing satisfactory PTB sockets because of inadequate training of prosthetist in the PTB technique. However, the TSB silicon liner socket has problems such as causing excessive perspiration, heating and odor etc. Therefore, a new socket is designed following the principle of alternative pressure and release to overcome the disadvantages and to check the socket with regard to stability, comfort and satisfaction. Method: A single case study of a person 37-year-old, with transtibial amputation population took part in this study and was selected according to the inclusion criteria. The participant was provided patient information sheet and after taking the informed consent, the assessment and fabrication of the new socket were being proceeded, taking the cast on the first day. On the third day the newly designed socket along with prosthesis was provided with an adaptation period of 7 days. After 7 days the patient was called to check the stability with standing, comfort and satisfaction with a prosthetic socket comfort score. Results and Discussion: The present socket is well suitable for transtibial patient in weight bearing position. It fits well to the contour of the adult patient. The socket was adjusted manually during rectification phase providing respective pressure in areas required. Conclusion: The developed socket had a great effect on gait pattern of transtibial amputee. This socket provides adjustment for pressure, anterior, posterior, medial and lateral of the stump. It also creates surface for the placement of bony prominences. As it is a complex casting procedure, proper care should be taken to fabricate the casting of socket with minimal error. Further, innovative inventions will be required to refine more products and extensive study has to be carried out on the existing mode. Key words: transtibial amputation, transtibial socket, tissue compression and release.

Management Issues

The development of a green-building project following a specific reference standard such as LEED, brings new conditions and restrains for all subjects involved in the process. Such changes affect technicians, owners, bureaucracy and also the management tasks either during design or construction phases.  Within this scope, project management plays a key role for the optimization of the design-project development. This research analyzes the design process of a single case-study project from the project management perspective, taking into consideration all the activities that negatively affected the project design development. The project selected for the scope of the research is a new school complex located in Northern Italy currently pursuing the LEED Gold certification with a project cost of 13,2 million Euros. A new methodology was created in order to analyze the project and evaluate the effects of detected project-management issues under three different points of view: costs, time and building sustainability. Such “issues” were identified by researchers on the basis of the LEAN-definition of “waste”. The scope of the research is to develop and test a methodology for the optimization of the project management processes during the development of a LEED building design in Europe through the detection and evaluation of process wastes. The results showed that project management issues related to green-building tasks affect considerably the cost, schedule and sustainability of the project design and vice versa, the accuracy of the project management tasks affect the sustainability features of the final building design.

Weight Bearing Area

Rotationplasty is established as a functionally improving and partially ablative method of tumour surgery, but good clinical and functional results do not only depend on a successful surgery. Due to the changed biomechanical situation the activity level is limited by the weight bearing capacity of the rotated foot. Painful blisters and callosities may limit the use of the exo-prosthesis, because the skin is overstressed in the soft socket. A 28-year-old patient with a rotationplasty type A2 suffered from painful callosities of the rotated foot. Capacitive pressure measurements were performed as well as a gait analysis for kinematics and kinetic characteristics. Clinically a decrease of the callosities and a pain relieve was obvious and the patient learned skiing without prior knowledge. Biomechanically a decrease of the peak pressure (from 240.6–135.0 kPa) and the mean pressure (from 83.2–66.2 kPa), was observed with an increased weight bearing area. The study has shown that a modification of the heel bench can considerably improve pressure distribution. An increase of the load bearing area appears to enable the skin to compensate even intensive strain during athletic activities.

Migratory farm labor like other forms of migrant work both in and outside agriculture impedes on the opportunity to make choices. The following essay explores particular phases in the life of one man (a single case study) and examines how he considers turning points in his life that led to a long period of substance use, both as an immigrant in the country and as a working man in his home country, followed by a cessation of use and the beginning stages of recovery. / Para el migrante, viajar en busca de trabajo es díficil, ya sea que trabaje en agricultura o en otras labores. Este ensayo examina ciertas etapas en la vida de un hombre (estudio de un solo caso) que examina los cambios que le han ocurrido durante un período en que él consumía grandes cantidades de alcohol en los estados y en su país, seguido por un período de sobriedad (no tomaba alcohol, no usaba drogas) en este país en que él comienza una etapa de rehabilitación.

Positive Effect

Interest in offering Entrepreneurship Education (EE) to all kinds of university students is increasing. Therefore, universities are increasing the number of entrepreneurship courses intended for students from different fields of study and with different education levels. Through a single case study of the Contamination Lab of Turin (CLabTo), we suggest how EE may be taught to all kinds of university students. We have combined design methods with EE to create a practical-oriented entrepreneurship course which allows students to work in transdisciplinary teams through a learning-by-doing approach on real-life projects. Professors from different departments have been included to create a multidisciplinary environment. We have drawn on programme assessment data, including pre- and post-surveys. Overall, we have found a positive effect of the programme on the students’ entrepreneurial skills. However, when the data was broken down according to the students’ fields of study and education levels, mixed results emerged.

Purpose-This paper examines the nature of services and processes of business incubation. Its specific objectives are to establish the nature of services offered by business incubation centers in Uganda, examine the incubation process and to establish the perception of business incu- batees about business incubation services using a case of FinAfrica a private social enterprise. Methodology-This paper presents findings from one incubation center FinAfrica as a case study. Ethnographic design is adopted while observation and interview methods are used to collect data. Results-Key services offered by FinAfrica incubation center include entrepreneurial training, provision of office space, legal and accounting services, mentoring, coaching, entrepreneurial networks and general office administration. The centre has a unique business incubation model which starts with motivating people to start businesses, capacity building, business registration, and ends with graduation after attaining capability for self-sustainability. Incubatees perceive the services offered by the incubation centre as helpful through training, affordable office space, entrepreneurial ecosystem and opportunities for a lean startup. Implications- While this study does not offer statistical inferences for generalisation because of the qualitative design and single case, the exploration of FinAfrica provides insights about how Incubation centers need to plan for positive and sustainable entrepreneurial impact for startups. There is need for more Government and other development partners’ involvement in business incubation and post incubation support for competiveness and growth. Originality/value- This study provides insights about the key services offered in the incubation process and provides insights into the perceived benefits of business incubation. It also contributes to literature about business incubation with practical evidence from an emerging economy whose focus is on private sector development and innovation promotion.
