Abstract Human movement data can contribute to the quality improvement of industrial and medical products affected by such movement. Such data can be used to improve the quality of industrial products as well as in healthcare applications, such as the development of artificial joints. To develop and design artificial joints with enhance durability, it is necessary to set up standards of durability using human movement data in daily life. The aim of this study is to obtain data that contributes to the improvement in durability of artificial elbow joints. We have developed a wearable device that can measure its self-acceleration, angular velocity, and quaternions to collect human movement data continuously for long-term. Additionally, we collected the arm movement data of 30 participants using the developed device. The participants of this study carried on with their normal lives with the measuring device worn on their wrist. This study calculated the posture of the wrist over time using quaternions and mainly analyzed posture changes. We clarified the characteristics and trends of the movement of bending the elbow in daily human life.

      Progress of technology and its developed is going so rapidly nowadays and it provide big affect on human life, some of them were education and daily life. Due to its development we also know the other form of calendar which is in digital form that we usually found in gadgets such as handphone or tablets and surely it is portable. Rinfo which is an email supporting facilities for the needs of Raharja College may help Pribadi Raharja in coordination and communication about task and/or event. Rinfo has some applications that integrated with Rinfo itself, such as RinfoGroup, RinfoSites, RinfoDocs, RinfoDrive, RinfoH and RinfoCal. RinfoCal is an calendar application that can be use as schedule time reminder application and it will send any reminder not only to one person but some or couple persons. RinfoCal may sent an pop-up notification or email notification. This paper will discuss about what is RinfoCal, how to use it, what’s the purpose of using RinfoCal, benefit of RinfoCal and so on. But, instead of its benefit, there are also some shortages including many people who using Rinfo doesn’t get the benefit of RinfoCal because they just pretending that RinfoCal is just an usual calendar.  This paper also present six problems from conventional reminder that will solved by RinfoCal fews are just doing reminders only once at a time or just remembering only one person, a mind mapping to simplify the analyze of problem and make the best solution, eight literature reviews that had been done to help analyzing problems of research.

Biomechanical analysis of human movement is based on dynamic measurements of reference points on the subject’s body and orientation measurements of body segments. Collected data include positions’ measurement, in a three-dimensional space. Signal enhancement by proper filtering is often recommended. Velocity and acceleration signal must be obtained from position/angular measurement records, needing numerical processing effort. In this paper, we propose a comparative filtering method study procedure, based on measurement uncertainty related parameters’ set, based upon simulated and experimental signals. The final aim is to propose guidelines to optimize dynamic biomechanical measurement, considering the measurement uncertainty contribution due to the processing method. Performance of the considered methods are examined and compared with an analytical signal, considering both stationary and transient conditions. Finally, four experimental test cases are evaluated at best filtering conditions for measurement uncertainty contributions.

Abstract Background As COVID-19 continues to spread around the world, understanding how patterns of human mobility and connectivity affect outbreak dynamics, especially before outbreaks establish locally, is critical for informing response efforts. In Taiwan, most cases to date were imported or linked to imported cases. Methods In collaboration with Facebook Data for Good, we characterized changes in movement patterns in Taiwan since February 2020, and built metapopulation models that incorporate human movement data to identify the high risk areas of disease spread and assess the potential effects of local travel restrictions in Taiwan. Results We found that mobility changed with the number of local cases in Taiwan in the past few months. For each city, we identified the most highly connected areas that may serve as sources of importation during an outbreak. We showed that the risk of an outbreak in Taiwan is enhanced if initial infections occur around holidays. Intracity travel reductions have a higher impact on the risk of an outbreak than intercity travel reductions, while intercity travel reductions can narrow the scope of the outbreak and help target resources. The timing, duration, and level of travel reduction together determine the impact of travel reductions on the number of infections, and multiple combinations of these can result in similar impact. Conclusions To prepare for the potential spread within Taiwan, we utilized Facebook’s aggregated and anonymized movement and colocation data to identify cities with higher risk of infection and regional importation. We developed an interactive application that allows users to vary inputs and assumptions and shows the spatial spread of the disease and the impact of intercity and intracity travel reduction under different initial conditions. Our results can be used readily if local transmission occurs in Taiwan after relaxation of border control, providing important insights into future disease surveillance and policies for travel restrictions.

Among the functional limitations associated with hip osteoarthritis (OA), the alteration of gait capabilities represents one of the most invalidating as it may seriously compromise the quality of life of the affected individual. The use of quantitative techniques for human movement analysis has been found valuable in providing accurate and objective measures of kinematics and kinetics of gait in individuals with hip OA, but few studies have reported in-depth analyses of lower limb joint kinematics during gait and, in particular, there is a scarcity of data on interlimb symmetry. Such aspects were investigated in the present study which tested 11 individuals with hip OA (mean age 68.3 years) and 11 healthy controls age- and sex-matched, using 3D computerized gait analysis to perform point-by-point comparisons of the joint angle trends of hip, knee, and ankle. Angle-angle diagrams (cyclograms) were also built to compute several parameters (i.e., cyclogram area and orientation and Trend Symmetry) from which to assess the degree of interlimb symmetry. The results show that individuals with hip OA exhibit peculiar gait patterns characterized by severe modifications of the physiologic trend at hip level even in the unaffected limb (especially during the stance phase), as well as minor (although significant) alterations at knee and ankle level. The symmetry analysis also revealed that the effect of the disease in terms of interlimb coordination is present at knee joint as well as hip, while the ankle joint appears relatively preserved from specific negative effects from this point of view. The availability of data on such kinematic adaptations may be useful in supporting the design of specific rehabilitative strategies during both preoperative and postoperative periods.

Debates about migration, whether led by politicians or scholars, often approach migration as a relatively new challenge and categorize it as a “destabilizing force,” ignoring the fact that the world’s past and present has been built by human movement. Humans have always migrated. Individual and population mobility as well as settlement are part of humans’ shared history. To integrate migration into an understanding of humans’ shared past, present, and emerging possible futures, several concepts prove useful including migration regime, displacement, dispossession, conjuncture, colonization, border-making, nationalism, and racialization. Deployed together, these concepts identify moments in human history in which migration has been understood to be part of the human experience and when, where, and how migrants have been stigmatized, and those who move defined as culturally or biologically inferior. By coupling the concept of migration regimes with an analysis of changing modes of dispossession and displacement over millennia, scholars can illuminate the intersection of the economic and political transformations of governance structures as well as the varying concepts of “the migrant” and “nonmigrant,” and “native” and “foreigner.” Anti-immigrant ideologies preclude discussion of the broader economic and political restructurings that underlie both increased human movement and anti-migrant sentiments. They also deflect attention from a set of questions that are at the heart of the anthropology of migration: Why do people leave familiar terrains, family, and friends? How do they manage to move and settle elsewhere? How do they relate to the life they left behind? These are questions that can equally be asked of people who move to another region of a country or travel across political boundaries. To answer these questions migration scholars have explored the linkages between forms of human mobility and processes of dispossession, displacement, and resettlement. In these investigations, social networks prove to be central to mobility and settlement. Since the 15th century, changing Western theories about human migration and the origins of political and social boundaries reflected transformations in political economy. Globe-spanning migration regimes used violent force, border formation and dissolution, documents, surveillance, and criminalization to allow the migration of some and disallow the movement or settlement of others. During that period, marked initially by colonialism and slavery, and then by nation state building and anticolonial struggles, migration scholars including the anthropologists took varying positions on the significance of mobility and stasis in human life. By the beginning of the 21st century, the accumulation of capital by dispossession emerged as a process increasingly central to a historical conjuncture marked by both heightened migration and anti-immigrant nationalism. Political struggles for social and environmental justice began to merge with movements in support of migration. This political climate shaped a new engaged anthropology of migration.
