This study analyzed the electric vehicle recharging station status with recharging time limitation due to long waiting time, and figured out the user status by user interviews. And then this study verified the validity of hypothesis in terms of environmental design perspective and suggested layout of recharging station model. 21 recharging stations in Korea and station operation cases of 7 countries were examined. Except for the USA, the reality of electric vehicle recharging station today is the 1st proving stage focusing on the infrastructure construction of electric vehicle recharging station. It focuses on performance of recharging facility, use efficiency and operation environment of electric vehicle. About the effective waiting time of the user to use it should be studied. The current conditions of recharging station are as follows: Lack of independent recharging space, lack of facility that reduces external effect of recharging space, and lack of lounge for users during the waiting time. These three are essential factors constructing a suggesting model after basic layout, which needs proper measurement on the long recharging time and long waiting time. The essential factors are applied to electric vehicle recharging station layout so that users might use 'digital refresh" i.e. lounge and information contents service during the waiting time which provides convenience of recharging and emotional space with users. Such upgrade recharging station environmental model might resolve the burden of long recharging time which may contribute to the popularization of electric vehicles.

In today's knowledge economy, various schemes are being devised in order to attain knowledge and understanding in the most effective ways possible. In an office environment, spatial concepts that encourage 'smart working' is becoming more prevalent; therefore allocating of space according to the types of work being performed, ways to maximise the work efficiency, and furniture arrangement to accelerate liaison among the users are being carefully considered. Especially in a space where its members are encouraged to communicate and collaborate, the furniture within that space need to be attractive and practical for its users, as well as efficient and effective for the firm the service is being provided for. In this study, we aim to offer furniture design service that satisfies such demands of the present time. Thus, instead of merely following a standard design process in which one approaches a project from design planes to an outcome, various aspects of the working environment will be considered such as the relationship between the space and the users, their needs, and the features of work being performed within the space. After attentive research and analysis, the results will be put into production from the user's point of view in mind. This study is intended to propose furniture design that embodies the characteristics of integrated working environment that can facilitate efficient use of the limited working space, productivity among the users, and promoting valuable corporate culture.

In space based constellation network, users are allowed to enter or leave the network arbitrarily. Hence, the number, identities and transmitted data of active users vary with time and have considerable impacts on the receiver's performance. The so-called problem of multiuser detection means identifying the identity of each active user and detecting the data transmitted by each active user. Traditional methods assume that the number of active users is equal to the maximum number of users that the network can hold. The model of traditional methods are simple and the performance are suboptimal. In this paper a Maximum A Posteriori Probability (MAP) based multiuser detection method is proposed. The proposed method models the activity state of users as Markov chain and transforms multiuser detection into searching optimal path in grid map with BCJR algorithm. Simulation results indicate that the proposed method obtains 2.6dB and 1dB E_b/N₀ gains respectively when activity detection error rate and symbol error rate reach 10^-3, comparing with reference methods.

Using a questionnaire, this study examined the users' consciousness through the human five senses on the waterside space in the district of Minato Mirai 21, Yokohama located in the east of Kanagawa prefecture, which is well known for its waterfront in Japan. Among the users, the results of the questionnaire showed 52.2% of male, and 29.6% accounted for people in their twenties as the dominant groups. Out of the nineteen questions regarding the consciousness on the waterside space, 'feel the sea breeze' accounted for 237(78.7%) while 'the sea is visible' accounted for 217(72.1%). Then, the contents of the nineteen questions were re-classified into such seven items as the human five senses(sight, hearing, touch, taste, and smell), activities, and the existence of facilities, discovering the consciousness of the users. The results demonstrated that touch(22.9%) and sight(20.8%) respectively were the most influential items.

Interface is a medium or channel to communicate between human and things, while interaction is the manner of communication between them. Interaction design is designing experience of user through the interaction process for human, thing, system, and space. Richard Buchanan suggests four kinds of interaction: interface (person to thing interaction), transaction (person to person interaction), human interaction (human and environment interaction) and participation (human to cosmos interaction). With digital technology, architecture and space design have made various experiments at form, function, and content of space. Space evolves from a physical container to a stage to provide narrative and create new experience to users. Since understanding users, creating experience, efficient space design, content planning, and applicable technology are required for interaction design in space, multi-disciplinary research and cooperation is needed.

This study aims to examine the educational function space of university dormitories at local universities with corridor centered structure in Honam area regions based on direct and indirect parameters on the whole satisfaction of users in residential environment factors and personal characteristics. First, according to relations among parameters, educational and cultural activities of four major activities within the dormitory had indirect influences on social activities, eating and sleeping activities had no direct influence on other activities. And social activity had direct influence on the general satisfaction as an important parameter and educational and cultural activities had indirect influence on the whole satisfaction through social activities. Detailed results show that, in the first educational activities directly affecting the lighting and air conditioning facilities (0.22), safety (0.326), Territoriality (0.327), the space density (-0.167), directions (-0.166) and yeohyang having personal characteristics and the safety of the second cultural activities (0.183), Territoriality (0.361), Aesthetics (-0.13) and the personal characteristics Sex (-0.179), the direct effect, third, and erosion has a direct impact on activity The flexibility of the space factor (-0.128) and Territoriality (0.38) and the personal characteristics grade (0.172), respectively. Fourth in social activities directly affecting the pathfinding (-0.104), and parameter, education (0.388) and cultural activities (0.445), and some of the factors affecting the indirect lighting and air conditioning facilities, safety, and Territoriality, the space density, directions, grade, they could influence through educational activities to be analyzed. That is, territoriality in educational function space is the important factor that users react very sensitively in educational, eating and sleeping activities and educational function space must secure area and division considering personal and public use as the space accommodating activity which is lacking in unit residential space. Accordingly, the safety of educational function space in university dormitory is considered as the fundamental safety matter on the fire prevention, hygiene and cleanness for users in the satisfaction of educational and cultural activities.

The restaurant is regarded as the place of association and rest, and is the commercial facilities required the space of delightful and comfortable in mentality as well as the visual satisfaction for the users. The customers have their tendency to avoid the visual and physical contact between the strangers in the restaurant. Therefore, it is required to arrange the undisturbed space from strangers through the appropriate guest seats arrangement by understanding such mental basement. In this study, we have examined the way of space application between the people in the space and the mental mechanism, and we made study and analysis on the conciusness & behavior of the users of the restaurant actually. As the result, the theoretical study was connected to the customers conscious or unconscious behavior and the same results was come out from the paper-and-pencil test and observation research, and its appropriateness was clarifed. To put it briefly , the people have been showing their trends to prefer the place where have a fine view, undisturbed from others and may keep to the private area. On the whole , they prefer the visual variation somewhat rather than the simple, and they are fond of the space of open and comfortable. and also showing that the mental environment could be established by the control of physical environment. Therefore, we can say that the restaurant is required to fulfill this spatial desire of the users through the guest seats arrangement and other visual factors.
