- This paper presents research performed on set-based multi-criteria optimization for the preliminary design of slab frame bridges. As a result of immense CO2 emissions emerging from concrete production, there is a need for optimization methods decreasing the volume of concrete without affecting the function of the structure. Previous research suggests a general correlation between CO2 footprint- and cost reduction, due to minimized material use. However, the aspect of buildability may conflict with lessened material, as optimized designs might simultaneously be less buildable. This research aimed to develop an optimization method with respect to the investment cost and environmental impact while also considering buildability cost aspects. The optimization algorithm shows the possibilities of reducing the environmental impact by up to 13.7% for a slightly increased cost of 2.3%. Thus, by implementing optimization procedures in the early stages of the planning process the holistic cost effects related to green solutions can be presented, favoring the choice of sustainable designs amongst clients during tendering procedures.

- PURPOSE: To investigate outdoor mobility of immigrants in Sweden who are living with the late effects of polio.MATERIALS AND METHODS: A total of 145 patients with late effects of polio born outside the Nordic region were identified at an outpatient polio clinic. Of these, 74 completed a questionnaire about their mobility and independence in daily life, self-perceived pain and depression, vocational status, mobility assistive devices/aids, transportation modes and driving. Patient characteristics were based on medical records supplied by physicians.RESULTS: Twice as many patients had lower extremities that were affected by polio than upper extremities. This affected their use of different transport modes and caused mobility and transfer problems. Indeed, 39% needed mobility aids and help from another person to move outdoors. Those who reported dependence for outdoor mobility were more often unemployed and more often depressed.CONCLUSIONS: Many respondents reported having difficulties with transport mobility, but a large proportion, 57%, were independent and active drivers. It is important to consider outdoor mobility when planning rehabilitation for patients with late effects of polio and foreign backgrounds. In addition to psychosocial factors, dependence on mobility-related activities can lead to dependency and isolation. Implications for rehabilitation Outdoor mobility and access to transport modes are important for independence and an active life and need to be included in the rehabilitation process. Both personal and environmental factors, can contribute to mobility problems of people with foreign backgrounds, who are living with the late effects of polio. Factors such as cultural, social and gender aspects are important when planning suitable and individualized rehabilitation.

- BackgroundThe aim of the study was to describe the experience of outdoor mobility among immigrants with late effects of polio living in Sweden. There is a need to understand more about this young group of persons since they often have problems with mobility and gait, but they may also face participation restrictions due to issues associated with integration into a new community and culture.MethodA total of 14 young immigrants with late effects of polio participated and were interviewed individually. The study used a qualitative method to explore personal experiences and the interviews were analyzed through an inductive approach, using qualitative content analysis.ResultsThe analysis led to a major theme; self-image and acceptance, that comprised a changeable process and experiences of cultural, social, and gender-specific barriers, but also of environmental and personal factors that impacted their outdoor mobility. By using a car, the participants felt they could come across as normal which also increased their self-esteem.ConclusionsIndependent mobility is a major enabler for ongoing employment and being able to use a car increases the chances for integration into society for young immigrants with late effects of polio. Public transport is not considered to be adequate or efficient enough due to the participants’ mobility impairments, but driving can prevent involuntary isolation and facilitate participation. A car can increase quality of life but may also be a facilitator for work and reduce the demand for societal support.
