AI faces important adjustments, and scientific foundations are confronted with new breakthroughs, as AI enters a new stage： AI 2.0. This paper briefly reviews the 60-year developmental history of AI, analyzes the external environment promoting the formation of AI 2.0 along with changes in goals, and describes both the beginning of the technology and the core idea behind AI 2.0 development.

The environmental construction should take the improvement and maintenance of the ecologically balance in housing estate as its aim and the coexistence between man and nature as its goal. By making an analysis of the current situation of afforestation, landscape, functional requirements and humanistic environment of the six residential quarters of Huilongguan Fengyayuan, Sainaweila,Xinxinjiayuan of the Asian Games, and others in Beijing, this paper presents an arrangement mode of plants in dwelling districts.展开更多

Urban areas have well-developed built environment features, whereas the rural areas are less walkable and this may influence the mode of transport. In general, active transport is more common in urban centers. Further, public transportation is more developed in urban areas, whereas motorized transport may be more widespread in the rural areas. Despite this, in Sogn & Fjordane, a rural county in western Norway, high PA levels are frequently observed. Thus, the aims of this study were to(1) explore perceived built environment features and characterize their associations with objectively measured PA levels in Norwegian adults and(2) explore the differences in these correlates between Sogn & Fjordane and the rest of Norway.Methods: In this cross-sectional study, participants used questionnaires to rate perceptions of their built environments, and their PA was objectively measured for 7 consecutive days using the Acti Graph GT1 M accelerometer. There were 972 Norwegian adults who were included in the study. The average age was 46.9 ± 6.5 years and 43.8% of participants were men. Data were analyzed using multiple linear regression.Results: Total PA and moderate-to-vigorous physical activity(MVPA) were both associated with perceived walkability, the community perception score, and active transport for commuting(all p ≤ 0.004). We also observed geographic-area-specific associations: the community perception score was negatively associated with total PA and MVPA in the rest of Norway(p ≤ 0.012) but not in Sogn & Fjordane. Public transport for commuting was positively associated with MVPA in Sogn & Fjordane(p = 0.03) but not in the rest of Norway.Conclusion: Total PA level and MVPA were associated with built environment factors, such as perceptions of community, perceived walkability,and engaging in active transport for commuting. Geographic differences in the PA correlates were observed, and thus, locally customized environmental population approaches aimed at increasing PA levels may be essential complements to individual behavior and lifestyle strategies.Further, objective measures of Norwegian built environments, such as geographic information system data, and validated walk-and bike-scores would advance the field.展开更多

One of the actions that took place as part of the above project was the creation of an in situ botanical garden in order to raise public awareness of the environment and the flora of the region. During the operation of the garden, the visitors answered questions related to their satisfaction or dissatisfaction of their visit. They also made suggestions for the improving of the garden. According to the number of the visitors and the analysis of the questionnaires, the operation of the garden was satisfactory. The in situ botanical garden proved useful not only for environmental awareness and education, but also for local economy. Two years since its creation, the garden eventually stopped operating. The main reason was lucky of funding. Based on the experience gained, it is suggested that the garden should be re-created under a new approach. Regions, such as Zagori, whose economy is based on environmental tourism, would benefit greatly from such structures. Moreover, in situ botanical gardens can play an important role in the protection of Greece＇s rich flora.展开更多
