    The field of city logistics can be characterized by its many local demonstrations and trials, that are quite often not lasting longer than the trial period. The number of demonstrations that continued and were implemented in daily practice is limited. Freight partnerships proved to be a good first step to engage stakeholders. This contribution proposes a new way to develop a more action-driven form of these partnerships that follows from a solution approach, which has proved successful worldwide in fostering innovation deployment, but has not yet been applied explicitly in the domain of City Logistics: Living Labs. The living lab approach ensures that the stakeholders are involved much earlier in the in planning and implementation processes, and that the proposed city logistics implementation is revised and continuously improved to meet stakeholder needs and obtain maximum impact for a long time. This contribution summarizes the steps that have to be taken to set-up and work in a city logistics living lab (CLLL). A CLLL can be defined as a dynamic test environment where complex city logistics innovations can be implemented, following a cyclical approach, where several solutions can be experimented and re-adjusted or improved to fit the real-life city challenges. In the Horizon 2020 project CITYLAB, we developed practical guidelines for establishing and running a city logistics living lab based on several living lab- and field test methodologies that enables stakeholders to set-up and run a CLLL. This contribution discusses the most important CLLL phases, roles, and characteristics, as well as the tools that are available. Next, this contribution shows the first results of cities in which CLLLs are actually set up, or already running. © 2016 The Authors

    Background: The purpose of this investigation was to undertake a hypothesis generating study to identify candidate variables that characterize people with knee osteoarthritis who are most likely to experience a positive response to exercise. Methods: One hundred and fifty participants with knee osteoarthritis participated in this observational, longitudinal study. All participants received a standard exercise intervention that consisted of 20-min sessions two to three times a week for three months. The classification and regression tree methodology (CART) was used to develop prediction of positive clinical outcome. Positive pain and disability outcomes (dependent variables) were defined as an improvement in pain intensity by \u3e50% or an improvement of five or more on the Oxford knee score, respectively. The predictor variables considered included age, sex, body mass index, knee osteoarthritis severity (Kellgren/Lawrence grade), pain duration, use of medication, range of knee motion, pain catastrophizing, self-efficacy and knee self-perception. Results: Fifty-five participants (36.6%) were classified as responders for pain intensity and 36.6% were classified as responders for disability. The CART model identified impairments in knee self-perception and knee osteoarthritis severity as the discriminators for pain intensity reduction following exercise. No variables predicted reduction of disability level following exercise. Conclusions: Such findings suggest that both body perception and osteoarthritis severity may play a role in treatment outcome with exercise. It also raises the possibility that those with higher levels of disrupted body perception may need additional treatment targeted at restoring body perception prior to undertaking exercise. Significance: Regardless age, sex, body mass index, pain duration, use of medication, knee range of motion, pain catastrophizing and self-efficacy, participants with knee osteoarthritis who report low levels of body perception disruption (a FreKAQ score ≦ 17) and minimal structural changes (KL grade I) demonstrate significantly better outcomes from exercise therapy than other participants

    Pattern formation of reaction-diffusion system having self-determined flow in the amoeboid organism of Physarum plasmodium

    The amoeboid organism, the plasmodium of Physarum polycephalum, behaves on the basis of spatio-temporal pattern formation by local contraction-oscillators. This biological system can be regarded as a reaction-diffusion system which has spatial interaction by active flow of protoplasmic sol in the cell. Paying attention to the physiological evidence that the flow is determined by contraction pattern in the plasmodium, a reaction-diffusion system having self-determined flow arises. Such a coupling of reaction-diffusion-advection is a characteristic of the biological system, and is expected to relate with control mechanism of amoeboid behaviours. Hence, we have studied effects of the self-determined flow on pattern formation of simple reaction-diffusion systems. By weakly nonlinear analysis near a trivial solution, the envelope dynamics follows the complex Ginzburg-Landau type equation just after bifurcation occurs at finite wave number. The flow term affects the nonlinear term of the equation through the critical wave number squared. Contrary to this, wave number isn't explicitly effective with lack of flow or constant flow. Thus, spatial size of pattern is especially important for regulating pattern formation in the plasmodium. On the other hand, the flow term is negligible in the vicinity of bifurcation at infinitely small wave number, and therefore the pattern formation by simple reaction-diffusion will also hold. A physiological role of pattern formation as above is discussed.Comment: REVTeX, one column, 7 pages, no figur

    本研究の目的は,地域高齢者との福祉体験学習における学生への教育効果と、地域貢献事業としての評価をすることである。徳島大学歯学部では,医療人を志すものとしての自覚を持つことを目的とした取り組みを県内16カ所の施設で合計28回実施した。これは,学生が口腔保健指導「お口の健康長寿教室」において,高齢者を対象とした口腔機能訓練の補助者として体験学習するものである。学習後のレポートから, 到達目標とした地域貢献の在り方や歯科専門職としての役割を認識する学生が多くを占めた。一方,地域貢献事業として評価するため,参加職員への調査を行った結果,利用者への役立ちに加え,多くの施設職員の理解も深まったとのアンケート結果が得られた。以上から,本取り組みは学生への教育目標「医療人としての自覚を持つ」に沿った成果が得られており,また,施設職員の口腔機能向上プ口グラムへの盤解の深まりから,今後の継続が期待される。The purose of this study is to evaluate the educational effect by the welfare-experience learning program with aged people in community,and to evaluate this program as the regional contribution. This program is to aim at having a consciousness of becoming the dental professional in the University of Tokushima,Faculty of Dentistry,and they were carried out with 16 institutions (a total of 28 times).This program makes students accompany the oral health guidance"long-life oral healthy classroom",and they carried out the experience study as on auxiliary person of the variaus functional oral-training for elderly people.By the investigation of the student's report, there are students who recognized the achievement objectives which are roles of the way concerning regional contribution as dental professionals in community. On the other hand,the questionnaire to the participating persoonnel was conducted in order to evalaote this program as the regional contrtbution. As a result,this program is useful to elderly people and the understanding of institution personnel is also deepened this practice. As mentioned above,the result of having is suitable for the educational goal "to have a consciousness of becoming the dental professional". Furthermore,this program was considered that future continuation is also expected by deepening of an understanding to the personnel's functional oral-training program
