Space perception is generally treated as a problem relevant to the ability to recognize objects. Alternatively, the data from shape perception studies contributes to discussions about the geometry of visual space. This geometry is generally acknowledged not to be Euclidian, but instead, elliptical, hyperbolic or affine, which is to say, something that admits the distortions found in so many shape perception studies. The purpose of this review article is to understand perceived shape and the geometry of visual space in the context of visually guided action. Thus, two prominent approaches that explain the relation between perception and action were compared. It is important to understand the fundamental information of how human perceive visual space and perform visually guided action for the convergence on embodied cognition, and further on artificial intelligence researches.

To reduce the accident rate caused by the delay of corrective action, which is common in the construction site, in order to shorten the time from correcting the existing system to the corrective action, I used a time similarity check to inform the inspectors of the problem in real time, modeling the system so that corrective action can be performed immediately on site, and studied a system that can actively cope with safety accidents. The research result shows that there is more than 90% opening effect and more than 60% safety accident reduction rate. I will continue to study more effective system combining voice recognition and deep learning based on this system.

Purpose: The purpose of this study was to propose more accurate mathematical model which can represent result of government quality assurance activity, especially corrective action and flaw. Methods: The collected data during government quality assurance activity was represented through histogram. To find out which distributions (Poisson distribution, Zero-Inflated Poisson distribution) could represent the histogram better, this study applied Pearson's correlation coefficient. Results: The result of this study is as follows; Histogram of corrective action during past 3 years and Zero-Inflated Poisson distribution had strong relationship that their correlation coefficients was over 0.94. Flaw data could not re-parameterize to Zero-Inflated Poisson distribution because its frequency of flaw occurrence was too small. However, histogram of flaw data during past 3 years and Poisson distribution showed strong relationship that their correlation coefficients was 0.99. Conclusion: Zero-Inflated Poisson distribution represented better than Poisson distribution to demonstrate corrective action histogram. However, in the case of flaw data histogram, Poisson distribution was more accurate than Zero-Inflated Poisson distribution.

Instant Messenger is a communication tool which allows instant real-time connection between parties through Internet Compared to the most popular Internet communication tool. email. the messenger allows people to check network presence of other parties and to connect in real time among multiple parties. Mostly due to the convenience it provides. use of instant messengers has increased tremendously not only for personal purpose but also for business purpose. However. firms are agonizing about the real impact of instant messenger usage among employees. whether the impact is positive or negative in terms of the productivity, Applying the theory of reasoned action (TRA) and technology acceptance model (TAM). this study sets UP perceived ease of use. perceived usefulness and cultural orientation of individuals as antecedents of adoption and use of the messenger application, Also. the impacts of messenger usage are measured as task productivity and intimacy among colleagues. This study presents several findings about the instant messenger, First. perceived ease of use. and usefulness play important roles in raising the adoption level of instant messenger. Also. culture propensity also maintains strong influence towards the actual usage of the messenger. Among cultural variables. innovativeness, supportiveness and outcome orientation reveal strong positive impacts on adoption and use of the messenger. On the dependent side. use of instant messenger seems to have a strong direct impact on task productivity as well as indirect impact through intimacy. Implications are discussed.

Purpose - This study investigated the effect of consumers' personal characteristics on their attitude toward social commerce focusing on the theory of reasoned action. Specifically, consumers' personal characteristics were further classified into personal characteristics, personal values concerning social commerce consumption, and consumption emotion concerning social commerce. Research Design, Data, and Methodology - The study investigated the relationship among consumers' personal characteristics, and the personal values of affirmative beliefs and attitudes of individuals toward social commerce based on the theory of reasoned action. A total of 151copies question nairewere evaluated, after excluding 13 copies having poor answers. Results - Consumers' personal characteristics were found to have a significant positive effect on their attitude toward social commerce. In addition, the most important personal characteristic affecting consumers' attitude toward social commerce was utilitarian value. Consumers' personal values were found to have a significant positive moderating effect between shopping value (i.e., hedonic and utilitarian values) and their attitude toward social commerce. Conclusion - The findings suggest that consumers' attitudes when trading with social commerce are affected by utilitarian value, and that companies should increase consumers' shopping value and build positive value about social commerce itself.

The purpose of this study was to investigate the effects of a Action Learning(AL) program in terms of problem solving, communication skills, emotional creativity and innovation behaviors. Design for this was a nonequivalent control group quasi-experimental study. The participants were C-hospital staff nurses in G city (Experimental group=29, Control group=30). The AL program was composed of fourteen sessions in eight weeks. Data were collected and the program was conducted from May. 26 to July. 18, 2008. Data were analyzed with ${\chi}^2$-test, Fisher's exact test, t-test and ANCOVA, and utilized the SPSS win 20.0 program. There were significant increases in problem solving skills, communication skills and emotional creativity in the experimental group compared to the control group. Considering the above results, AL program has proven to be an effective educational program for improving the problem solving, communication skills and emotional creativity of nurses.

Purpose: This study aims to identify effective ways to induce water resources conservation for general water consumers. Methods: In order to find the core factors to motivate water saving behavior for general consumers, this study utilized the theory of reasoned action which is well known as one of the most frequently used theory in consumer's green behavior analysis. Results: Among six hypothesized relationships in the research model four were proved to be statistically significant. The relationship between attitude toward water savings and the water saving behavior was found to be significant but only through the behavioral intention. Conclusion: Consumers with positive attitude on water conservation will practice water saving behavior with behavioral intention. However, consumers only with high knowledge on water conservation naturally and habitually practice water saving behavior without recognizing the intention to save the water. Thus, both positive attitude on the water conservation and subjective norm must be satisfied since the two factors tend to lead to actual green behavior using different psychological routes.

The knowledge management starts from the enhancement of learning capability in the members of the organization. The strategic change into the learning organization should be aligned with the change of organizational strategy, structure and processes. The study employed action learning methodology to transform the traditional organization into the learning one. The learning organization project has been successful thanks to the members' zeal and consensus to change the processes. However, not every learning team has been so successful. Some cases complained time consuming where others expect to be helpful for their incentives. The researchers concluded that the most important point for success of the learning organization project should be the support of top management.
