The extraction and recognition of human motion characteristics need to combine biometrics to determine and judge human behavior in the movement and distinguish individual identities. The so-called biometric technology, the specific operation is the use of the body's inherent biological characteristics of individual identity authentication, the most noteworthy feature is the invariance and uniqueness. In the past, the behavior recognition technology based on the single characteristic was too restrictive, in this paper, we proposed a mixed feature which combined global silhouette feature and local optical flow feature, and this combined representation was used for human action recognition. And we will use the KTH database to train and test the recognition system. Experiments have been very desirable results.

This study investigated the formation of communication education which is based on the contemporary language education. Concretely I watched chronologically the proportion of culture element and behavior element, its change, and the contents of writing education. To achieve this, I took the ancient Greek language education as the main materials. The sophists are right if we think only the empirical world, because of the changeability of external world and the relativity of sense. On the other hand, Platon emphasized the ability of abstract thought which is inherent in the human inside. But today's education only emphasizes the 'expression' which came from the Platonic thought. So students fills their devastated inside with arbitrary idea in this history-forgotten social circumstance. It is very beneficial to make subject have some cultural studies and to enhance the sensation on the world through the writing of representation because these can be good to the growth of subject. It is our-not as educator but as a predecessor of human being-duty to set the catalogue of cultural studies of this age and to make students feel the fundamental harmony and the beauty of the world.

The choice of the motion features influences the result of the human action recognition method directly. Many factors often influence the single feature differently, such as appearance of the human body, environment and video camera. So the accuracy of action recognition is restricted. On the bases of studying the representation and recognition of human actions, and giving fully consideration to the advantages and disadvantages of different features, the Dense Trajectories(DT) algorithm is a very classic algorithm in the field of behavior recognition feature extraction, but there are some defects in the use of optical flow images. In this paper, we will use the improved Dense Trajectories(iDT) algorithm to optimize and extract the optical flow features in the movement of human action, then we will combined with Support Vector Machine methods to identify human behavior, and use the image in the KTH database for training and testing.

The purpose of this study was to examine the effects of paternal marital satisfaction and caregiving behavior on children's paternal representations. 112 preschoolers(67 boys and 45 girls, aged 4-5) and their fathers participated in this study. The data were analyzed using descriptive statistics and structural equation modeling analysis. The results were as follows: firstly, paternal marital satisfaction had a direct effect on caregiving behaviors. Secondly, paternal caregiving behavior did not have a direct effect on children's paternal representations. Thirdly, paternal marital satisfaction had a direct effect on children's paternal representations. Fourthly, paternal caregiving behavior did not have a mediatory effect between paternal marital satisfaction and children's paternal representations. In conclusion, paternal marital satisfaction has influenced on caregiving behavior and children's paternal representations.

This paper proposes a new video-based method of analyzing human gait which is a highly variable dynamic process. It captures a human gait of varying directions as a trajectory in the phase space. The proposed method includes two options of a stochastic process model and a self-organizing feature map as the tool of feature space representation and analysis. Test results show that the model is highly intuitive and we believe it can contribute to our understanding of human activity as well as gait behavior.

Film was invented by human's desire to copy the real world, starting in the late 19th century. Since the birth of cinema, It was given mission to replay of the real world. On the other hand, cinema was regarded as a fictitious art form. Although the invention of film brought about experience of replaying of the real world it has been reproduced reality with creative story. And it also has been represent reality with sense of reality. Cinema's way of reproduction implied conflicting concept of mimesis. Triple Mimesis of Paul Ricoeur was an idea expanded into an analytical concept from that simple concept of mimesis. The purpose of this study was to examine the prefiguration of shown behavior in Columbine High School massacre based on Triple Mimesis of Paul Ricoeur. It also was to examine a form of representation on cinema which is 'Elephant' and studied how the form of representation on Elephant could interpret by audience. It could be define the relationship between reality and reproduction through this esthetic study. This paper attempted to build the method communication between the originator and audience with a whole analytic process of time and story on the cinematic representation.

With the advance of robot capabilities and functionalities, construction robots assisting construction workers have been increasingly deployed on construction sites to improve safety, efficiency and productivity. For close-proximity human-robot collaboration in construction sites, robots need to be aware of the context, especially construction worker's behavior, in real-time to avoid collision with workers. To recognize human behavior, most previous studies obtained 3D human poses using a single camera or an RGB-depth (RGB-D) camera. However, single-camera detection has limitations such as occlusions, detection failure, and sensor malfunction, and an RGB-D camera may suffer from interference from lighting conditions and surface material. To address these issues, this study proposes a novel method of 3D human pose estimation by extracting 2D location of each joint from multiple images captured at the same time from different viewpoints, fusing each joint's 2D locations, and estimating the 3D joint location. For higher accuracy, the probabilistic representation is used to extract the 2D location of the joints, considering each joint location extracted from images as a noisy partial observation. Then, this study estimates the 3D human pose by fusing the probabilistic 2D joint locations to maximize the likelihood. The proposed method was evaluated in both simulation and laboratory settings, and the results demonstrated the accuracy of estimation and the feasibility in practice. This study contributes to ensuring human safety in close-proximity human-robot collaboration by providing a novel method of 3D human pose estimation.

Abstraction applied in computer networking hides network details behind a well-defined representation by building a model that captures an essential aspect of the network system. Two current methods of representation are available, one based on graph theory, where a network node is reduced to a point in a graph, and the other the use of non-methodological iconic depictions such as human heads, walls, towers or computer racks. In this paper, we adopt an abstract representation methodology, the thinging machine (TM), proposed in software engineering to model computer networks. TM defines a single coherent network architecture and topology that is constituted from only five generic actions with two types of arrows. Without loss of generality, this paper applies TM to model the area of network monitoring in packet-mode transmission. Complex network documents are difficult to maintain and are not guaranteed to mirror actual situations. Network monitoring is constant monitoring for and alerting of malfunctions, failures, stoppages or suspicious activities in a network system. Current monitoring systems are built on ad hoc descriptions that lack systemization. The TM model of monitoring presents a theoretical foundation integrated with events and behavior descriptions. To investigate TM modeling's feasibility, we apply it to an existing computer network in a Kuwaiti enterprise to create an integrated network system that includes hardware, software and communication facilities. The final specifications point to TM modeling's viability in the computer networking field.

This article proposes an interwoven three-part framework for conceptualizing and analyzing the role of information in human activities, melding the cognitive and affective domain of the individual, the collective domain of the social, and the domain of signification and communication practices, focusing on the ways in which individual characteristics, social context and interaction, and signification and representation work together to form information behavior. The article presents an overview of each of these three domains and discusses the ways in which they are intertwined. It argues that considering the three domains in relation to each other offers a holistic framework within which to consider the ways in which information - needs, behavior, creation, and use - depends simultaneously on all three. It concludes by offering a brief discussion of the implications of the framework for information services, including (but not limited to) libraries.
