“…However, because of the high density and complexity of the crowd, it is easy for emergencies to occur within the crowds during mass events [11,12], including trampling accidents [13], such as the Shanghai stampede on the bund and the Love Parade disaster, which resulted in injuries and deaths [14]. Obviously, it is a difficult and important task for organizers to manage crowds [15,16]. Therefore, this paper focuses on the safety issues of HATCs due to their high potential risk, which will be useful for the management of HATCs.…”

The safety of highly aggregated tourist crowds is a challenging and important issue. This paper not only provided a comprehensive analysis of the accidents of highly aggregated tourist crowds but also determined the occurrence mechanism and coping paths. Based on the analysis of multiple cases, we found that the variable status of highly aggregated tourist crowds was the result of the interaction of three main elements: multisource pressure, state mutations and management responses. A series of factors interact and result in accidents, and the lack of a management response or a low-quality management response is the root cause of such accidents. A high-quality management response is a basic safety precaution for highly aggregated tourist crowds. Therefore, forming a virtuous circle of multisource pressure, state mutations and management responses is an effective path for coping with accidents.

“…Overcrowding was a major factor for the occurrence of a stampede. Crowd density reportedly influenced the outcome more than the absolute number of attendees 54 . Even if the global density of a mass gathering was low, the local density in specific locations could be very high, as the crowd was not distributed evenly throughout the venue 43 …”

“…Expanding the surface can be achieved by adding another dimension, such as higher floors 43 . Zig-zag shapes prevent congestion during panic, but they are unpractical in normal situations 54 57 Increasing a bottleneck space is only a temporary solution, whereas minimizing pedestrian speeds at specific locations may reduce the risk of a crowd disaster 47 …”

Human stampedes are a major cause of mortality in mass gatherings, but they have received limited scientific attention. While the number of publications has increased, there is no recent review of new study results. This study compiles and reviews available literature on stampedes, their prevention, preparedness, and response.A search for peer-reviewed and grey literature in PubMed (National Center for Biotechnology Information, National Institutes of Health; Bethesda, Maryland USA), Google Scholar (Google Inc.; Mountain View, California USA), Web of Science (Thomson Reuters; New York, New York USA), the World Health Organization Library Database (WHOLIS; World Health Organization; Geneva, Switzerland), and ReliefWeb (UN Office for the Coordination of Humanitarian Affairs; Geneva, Switzerland) was conducted, and papers were selected according to pre-defined eligibility criteria. Included items were read and results were compiled and summarized. A total of 64 publications were included, of which, 34 were published between 2013-2016. The most studied events were Germany’s Love Parade stampede in 2010 (Duisburg, Germany; n = 6) and the United Kingdom (UK) Hillsborough Stadium stampede in 1989 (Sheffield, England; n = 4). Conflicting definitions of human stampedes were found. The common belief that they result from an irrational and panicking crowd has progressively been replaced by studies suggesting that successive systemic failures are main underlying causes. There is a lack of systematic reporting, making news reports often the only source available. Prevention measures are mainly related to crowd management and venue design, but their effectiveness has not been studied. Drills are recommended in the preparedness phase to improve coordination and communication. Delay in decisions, poor triage, or loss of medical records are common problems in the response, which may worsen the outcome.Stampedes are complex phenomenon that remain incompletely understood, hampering formulation of evidence-based strategies for their prevention and management. Documentation comes mostly from high-profile events and findings are difficult to extrapolate to other settings. More research from different disciplines is warranted to address these gaps in order to prevent and mitigate future events. A start would be to decide on a common definition of stampedes.Moitinho de AlmeidaM,von SchreebJ.Human stampedes: an updated review of current literature.Prehosp Disaster Med.2019;34(1):82–88.

“…Among the tools to support innovation and creativity, TRIZ that means in English: "Theory for Inventive Problem Solving", and is a specific support for innovation development project, product or process engineering or technology. More surprisingly, the reference of the concept TRIZfractal that means self-similarity in transformations based on TRIZ tools to address knowledge management TRIZ (Pin et al, 2011) uses the matrix of contradictions and innovative principles in order to solve problems (Berdanosov and Redkolis, 2011). Another tool of this group is known as "Creative Design".…”

Nowadays, companies, even the small ones, need to use more efficient working methods such as "transnational." The market may still be local or regional, but the competition is global. To be competitive, companies need to develop innovative products and introduce them to the market at an acceptable price, in proper time and with a higher quality level. According to some authors, the survival strategy of the companies is related to the development of methodologies that are able to design, develop and provide, through efficient processes, innovative products and high quality. In this context, this paper aims to classify and characterize the main methodologies and tools used in new products development. This aims are supported by the graphs theory that is briefly addressed.
