The method relies on the two cues of the human appearance model and spatio-temporal information between cameras. For the human appearance model, an HSV color histogram is extracted from different human body parts （head, torso, and legs）, then a weighted algorithm is used to compute the similarity distance of two people. Finally, a similarity sorting algorithm with two thresholds is exploited to find the correspondence. The spatio- temporal information is established in the learning phase and is updated incrementally according to the latest correspondence. The experimental results prove that the proposed human tracking method is effective without requiring camera calibration and it becomes more accurate over time as new observations are accumulated.展开更多

Due to the diversity of individual's anthropometric measurements, the individualized customization technology is needed to get convincing sound. In this paper, we proposed a simple and effective method for modeling relationships between anthropometric measurements and Head-related Impulse Response(HRIR). Considering the relationship between anthropometric measurements and different HRIR parts is complicated, we divided the HRIRs into small segments and carried out regression analysis between anthropometric measurements and each segment to establish relationship model. The results of objective simulation and subjective test indicate that the model can generate individualize HRIRs from a series of anthropometric measurements. With the individualized HRIRs, we can get more accurate acoustic localization sense than using non-individualized HRIRs.展开更多

U.S. guidelines recommend ≥30 min of moderate exercise for healthy pregnant women most days of the week; however, most women do not meet these recommendations. Theory assists in identifying salient determinants of health behavior to guide health promotion interventions; however, the application of theory to examine PA among pregnant women has not been examined cohesively among multiple levels of influence(e.g.,intrapersonal, interpersonal, neighborhood/environmental, and organizational/political). Subsequently, this systematic review aims to identify and evaluate the use of health behavior theory in studies that examine PA during pregnancy.Methods: Articles published before July 2014 were obtained from Pub Med and Web of Science. Inclusion criteria applied were:(1) empiricallybased;(2) peer-reviewed;(3) measured factors related to PA;(4) comprised a pregnant sample; and(5) applied theory. Fourteen studies were included. Each study's application of theory and theoretical constructs were evaluated.Results: Various theories were utilized to explain and predict PA during pregnancy; yet, the majority of these studies only focused on intrapersonal level determinants. Five theoretical frameworks were applied across the studies—all but one at the intrapersonal level. Few determinants identified were from the interpersonal, neighborhood/environmental, or organizational/political levels.Conclusion: This systematic review synthesized the literature on theoretical constructs related to PA during pregnancy. Interpersonal, community,and societal levels remain understudied. Future research should employ theory-driven multi-level determinants of PA to reflect the interacting factors influencing PA during this critical period in the life course.展开更多

Questionnaires were submitted to 400 nurses and of which 386 were completed, resulting in a response rate of 96.5%. A sample of this size ensured the validity and reliability of the results. The data were analyzed using statistical analysis and techniques such as frequencies, means and path analysis using computer software SPSS for Windows 15.0 and LISREL 8.72. The results demonstrate （1） a significant, direct, and positive effect of personality on physical self-description; （2） a significant, direct, and negative effect of physical self-description on social physique anxiety; and （3） an indirect negative effect of personality on social physique anxiety through physical self-description. All paths in the model were significant （p 〈 0.05）. Analysis using linear structural relational model （LISREL） demonstrated the suitability of the framework and proved that the model used was applicable for this research. The results of this research will be used as a reference to develop strategies for human resource management in Taiwan Residents hospitals.展开更多

Appraisal theory proposed by Martin and White （2005） is used to analyze the data taken from the Jakarta Post, an Indonesian newspaper written in English. The theory is an extension of Halliday＇s Systemic Functional Linguistic. It offers the interpersonal relations between participants involved in the context. Appraisal in terms of attitude, engagement, and graduation is critically used to evaluate the collected data. The result of the study shows that the use of strong judgment as indicated by the absence of modality shows that the appraisers try to get public support.展开更多

For that, the theoretical reference of the research involves the analysis of the parameters according to the aspects that involve the use interactions of packaging in agreement with the definition and scientific concepts of ergonomics, allied to the development of product projects, discussing forms, handling, load transportation and the support of the product. Therefore, improperly handling of the packaging may cause damages to the products and even potential accidents. Coding and decoding are significant to facilitate the use recognition within the individual＇s repertoire. The packaging, within the macro-ergonomics universe, may be the object of ergonomics, whose contribution to solve problems is related to labor activities, by dealing with packaging, transportation and load resulting from the man-object interaction. The incorrect identification of information may lead to problems of interpretation and misuse, from the handling to the disposal of packaging. For this reason, this research suggests the adjustment of the man-object interface which may lead users to make mistakes regarding use and important choices, through adequate handling actions.展开更多

It showed that the international system and governance mechanism was unable to adapt to the new global situation or solve the new challenges and problems caused by the rapid development of globalization. Global governance needs to explore new ideas, new paths and new strategies. However, to advance the transformation and development of global governance, in-depth cooperation by the great powers is not all that is involved; also inevitable are the redistribution of international power, interests and responsibilities, contradictory global concepts and fierce competition among the great powers. The next five to ten years are a key period both for the transformation and development of global governance and for China＇s full-scale rise. The latter is not only a process of China＇s integration into the global governance system but also a process whereby China influences global governance reform. China should seize the opportunity of the global governance crisis and changes to promote benign interaction between China and the world and should become an advocate, designer, shaper and leader in the improvement of the global governance system, focusing on the construction of national governance, the governance of East Asia, global governance and the governance of certain advantageous fields. Its active assumption of the historic mission of the new era of globalization has laid a solid foundation for China to grow into a great major country.展开更多
