There has been recent interest in intelligent vehicle technologies, such as advanced driver assistance systems (ADASs) or in-vehicle information systems (IVISs) that offer a significant enhancement of safety and convenience to drivers and passengers. However, unsuitable design of HMI (Human Machine Interface) must increase driver distraction and workload, which in turn increase the chance of traffic accidents. Distraction in particular often occurs under a heavy driving workload due to multitasking with various electronic devices like a cell phone or a navigation system while driving. According to the 2005 road traffic accidents in Korea report published by the ROad Traffic Authority (ROTA), more than 60% of the traffic accidents are related to driver error caused by distraction. This paper suggests the structure of vehicle environment for real-time driving behavior monitoring system while driving which is can be used the driver workload management systems (DWMS). On-road experiment results showed the feasibility of the suggested vehicle environment for driving behavior monitoring system.

This research was aimed at finding clues of improving behavioral affordance of the residential environment by scrutinizing change of the residents' behavior in a livingroom depending on the child's development stage. 30 double-income families with one child were the subjects of depths interview, survey, observation of this research, who were residents of 3-bedroom apartment housing in Seoul. They presented obvious different behavioral patterns according to their child's development stage. Breeding and playing behavior were prior to the others when their child was in childhood, then relaxing with TV and PC behavior were getting superior when their child was in school period. It is important that residents perceive that the numerous types of behavior may take place in a livingroom, some of which has originated in our long residential culture. And then real housing should be provided to them that has proper behavioral affordance to support all those behavior. Housings with minimum walls and rooms would make it possible. A family has its inner dynamics can live a sustainable life in that housing as a home, that lasts along their whole life.

I suggested the design learning environment based on affordance concept approach for supporting and improving learners' behavior and outcome for convergent design education in this study. The design learning space should be applied teaching and learning activity, especially learners' behavior, physical space condition to support the design thinking process. The design learning space needs openness, individuality and connectivity to support the learners' behavioral to immerse, participate, cooperate, understand, think and fulfill the design thinking process. The composition principles of the learning environment for convergent design education supports communication and collaboration among members for independence and interaction. The spaces for design research and teaching needs high privacy while facilitating visual communications through special materials and wall structure design. Also, for connectivity to improve the learners' physical and visual contact, the environment of the classrooms requires flexibility and mobility by providing an open space integrating unit cells for realizing learning purpose. These are provided by formed of an open structure for inducing visual communication and physical contact to involve the design activities and the mutual interchange.

In order to solve problems in an uncertain and complicated management environment of the modern world, a creative solution that combines diverse perspectives, knowledge, and effort based on diversity within an organization is required. Smart work environment provides an opportunity to express the potential diversity of an individual, extending the source of ideas to the organization, enhancing communication, and linking and sharing information and knowledge. So, this results in increased creative behavior. The purpose of this study is to investigate the effect of the process of connecting and sharing information and knowledge of organizational members on creative behavior and the effect of smart work environment in the process. The purpose of this study is to identify roles of job autonomy, self-efficacy, knowledge sharing and smart work environment in creative process. For the study, 353 surveys with work use group(156 people) and unused group(197 people). Statistical analysis included validity and reliability analysis, structural model analysis. The results showed that self-efficacy and job autonomy had positive effects on creative behavior and knowledge sharing, and job autonomy had a positive effect on self-efficacy. Knowledge sharing has a positive effect on creative behavior, and mediates the relationship between self-efficacy, job autonomy and creative behavior. Particularly, knowledge sharing has a more positive effect on smart work use group. In case of smart work use group, self-efficacy and job autonomy have a relatively high influence on knowledge sharing rather than direct influence on creative behavior appear. This result implies that the achievements of smart work are revealed in terms of knowledge sharing and creative behavior.

As the population of preschooler increases with the increment of employed women today, the physical environment of day-care center is becoming an important factor for the preschooler as well as home environment. In order to create a suitable and desirable day-care environment for preschoolers, the using behavior of the preschoolers, who are the main users, needs to be applied to the spacial design. In this research, play preference area of Korea and United States which have different physical environments are analyzed. Child behavior observation analysis technique, interview with the teacher in charge, floor plan and furniture arrangement plan of the day-care centers and photography were performed for this research. The subjects were 63 preschoolers of 50 months old who are using Korean and American day-care centers and play of five minutes per preschooler was filmed for 3 days. Total 01 189 motion pictures were analyzed for this research. As a result, the physical environment, programs, preference area and finally the similarity and difference according to the gender were clarified for each countries' day-care center. The Korean preschoolers preferred the block area most, the second most favorite area being art for the younger class and language for older class. According to the gender, girls preferred language area while boys chose block area. On the other hand in American preschoolers' case, due to the large variety of play area, the play preference was distributed among various area except several high preference area. Based on this research, when designing indoor play area of day care centers, the area of block, language, and art which are popular play preferences should be considered firsthand, and gender preference is also needed to be thought of. These results may be used as an important data for planning the day care center play area in the future.

As recent virtual reality technologies provide a more natural three-dimensional interactive environment, users naturally learn to explore space and interact with synthetic objects. The virtual reality researcher develops a technique that realizes realistic sensory feedback to get appropriate feedback to sense input behavior. Although much recent virtual reality research works extensively consider the human factor, it is not easy to adapt to all new virtual environment contents. Among many human factors, distance perception has been treated as very important in virtual environment interaction accuracy. We study the experiential virtual environment with the feature of the virtual object connected with the real object. We divide the three-dimensional interaction, in which distance perception and behavior have a significant influence, into two types (whole-body movement and direct manipulation) and analyze the real and virtual visual distance perception heterogeneity phenomenon. Also, we propose a statistical correction method that can reduce a near-body movement and manipulation error when changing the interaction location and report the experiment results proving its effectiveness.

Advance of the Internet environment is applied not only to information search but also to the area of consumption behavior. Current research analyzes online use behavior and online information search of consumers in terms of users' perception. With the result of the research, it is noticed that promotion focus brings broader variation of information use behavior, and utilitarian value has a beneficial impact on the online exploratory information search. In addition, it is revealed that the more exploratory the information search is, the wider the range of online shopping information search is. Finally, people who have utilitarian shopping value showed more exploratory behavior in online search, especially for the search of informational products, than those who have hedonic shopping value. Present research is believed to improve practical influence of consumers' personality on online use behavior when customers purchase search products online. As a result, it would contribute to consumer research and marketing held online.

The purpose of this study was to determine the effect of a pleasantly designed interior inpro-spatial behavior. For pleasantly designed interior, the existing interior was remodeled through the change of finishing materials for major architectural elements such as wall, floor and ceiling, and changes of furniture and it's arrangement. Prospatial behavior was operationalized as seat arranging behavior and measured through the arranged condition and observable arranging behavior. Time-series design, one of quasi-experimental design was used. The data in this study were extracted from an existing field experimental research. One hundred forty four video tapes recorded during 6 months out of 2 years period ware used. In conclusion , the pro-spartial behavior change was a mid-term positive effect of pleasantly designed environment. In an environmental setting where pro-spatial behavior was most important, a certain time cycle to change the environment needs to be considered.
