With the development of deep learning technology and advances in computing power, video-based research is now gaining more and more attention. Video data contains a large amount of temporal and spatial information, which is the biggest difference compared with image data. It has a larger amount of data. It has attracted intense attention in computer vision. Among them, motion recognition is one of the research focuses. However, the action recognition of human in the video is extremely complex and challenging subject. Based on many research in human beings, we have found that artificial intelligence-like attention mechanisms are an efficient model for cognition. This efficient model is ideal for processing image information and complex continuous video information. We introduce this attention mechanism into video action recognition, paying attention to human actions in video and effectively improving recognition efficiency. In this paper, we propose a new 3D residual attention network using convolutional neural network based on two attention models to identify human action behavior in the video. An evaluation result of our model showed up to 90.7% accuracy.

In this paper, we propose a novel method for analyzing human interactions based on the walking trajectories of human subjects. Our principal assumption is that an interaction episode is composed of meaningful smaller unit interactions, which we call 'sub-interactions.' The whole interactions are represented by an ordered concatenation or a network of sub-interaction models. From the experiments, we could confirm the effectiveness and robustness of the proposed method by analyzing the inner workings of an interaction network and comparing the performance with other previous approaches.

The purpose of this study was to explore the effect of need for closure on college students' problem recognition and communication behavior. Specifically, this research examined differences about situation recognitions and communication behaviors across level of need for closure factors (preference for order and structure, preference for predictability, decisiveness, discomfort with ambiguity, closed-mindeness). The results show that the participants with higher level of discomfort with ambiguity and low level of closed-mindeness are more likely to high problem recognition, constraint recognition, involvement recognition, and doing active communication behaviors.

In this paper, we propose a method which recognizes human activity using model-based gaze direction estimation in an indoor environment. The method consists of two steps. First, we detect a head region and estimate its gaze direction as prior information in the human activity recognition. We use color and shape information for the detection of head region and use Bayesian Network model representing relationships between a head and a face for the estimation of gaze direction. Second, we recognize event and scenario describing the human activity. We use change of human state for the event recognition and use a rule-based method with combination of events and some constraints. We define 4 types of scenarios related to the gaze direction. We show performance of the gaze direction estimation and human activity recognition with results of experiments.

The purpose of this study is to examine how SMEs' perception of organizational support affects turnover intention, and to investigate the moderating effect of abusive supervisionin the relationship between organizational support perception and turnover intention. As a result of the analysis of the study, First, it was confirmed that organizational support perception had a negative (-) effect on turnover intention. Second, the higher the organizational support awareness, the lower the turnover intention, but when the abusive supervision in intervened, it was found that the organizational support perception offsets the effect that reduces the turnover intention again. That is, emotional support, turnover intention still appeared even if the abusive supervisionin was involved, but instrumental support had no effect on turnover intention when the abusive supervisionin was involved. This study is meaningful in that it expanded the scope of manufacturing services, semiconductors, and IT industries of SMEs with high turnover intentions.
