This study discusses "mechanisms" in a research facility, specifically focusing on the question of how we can understand what happens in the physical environment and the communication between researchers. This study attempts to address this question by examining two physical settings, before and after the move of one research-educational facility, the Institute of Paper Science and Technology. The objective of the study is to suggest conceptual models to comprehend the relationships between spatial layouts and communication. The study examines the underlying mechanism of how the levels of communication meet the layers of spatial structure. The paper has four parts. First, the preceding studies will be reviewed evoking some issues of communication and physical setting in research facilities. Second a conceptual typology in office plan will be developed providing a theoretical framework to review the spatial organization of the subject research facility, the Institute of Paper Science and Technology (IPST). Third, the spatial organization of the former building (before the move) and the present building (after the move) of IPST will be analyzed. Finally, conceptual models of the mechanism between the communication and the spatial organization will be drawn up.

This study empirically verified the effect of enterprise SNS usage on communication and work performance and the effect of communication on work performance for corporate employees. To accomplish the purpose of this study, we proposed a research model, set up research hypotheses, and verified the hypotheses based on previous studies. For this study, we surveyed the employees of manufacturing companies located at Ulsan city. The results of this study are summarized as follows. First, the use of enterprise SNS has a significant effect on communication. Second, communication has a significant effect on work performance. Third, the use of enterprise SNS has a significant effect on work performance. Through the results of this study, it can be confirmed that the introduction and utilization of enterprise SNS suitable for enterprises leads to the satisfaction of employees' communication and improvement of the work performance.

The purpose of this study is to help researchers and librarians in theory and practice. Communication was defined, and functions of communications were explained variously. It was to understand clearly the process of communication that some models of communication were presented. Barriers of effective communication were investigated and how to improve communication was suggested in order to overcome barriers of communication.

Tele-Gesture is a tangible user interface(TUI) device that allows a user to physically point to a 3D object in real life and have their gestures play back by a robotic finger that can point to the same object, either at the same time, or at another point in time. To understand the extent of the gestures as new way of digital collaborative communication, collaboration situation and types were experimented as TUI implementations. The design prototype reveals that there is a rich non-verbal component of communication in the form of gesture-clusters and body movements that happen in an digital communication. This result of analysis can contribute to compile relevant contributions to the fields of communication, human behavior, and interaction with high technology through an interpretive social experience.

The purpose of this study was to determine whether there are differences in the verbal interactions of earth science gifted depending on their communications structures and group status in small group activities. To this end, a small group activity was conducted to measure the density of the earth, and 8 small groups were selected, including 4 co-ownership type and 4 monopolistics type groups with different communication structures. And then, the framework was developed for analyzing verbal interactions to compare the differences in characteristics between small groups. The results are as follows. First, regardless of the communication structures, there were showing a simple pingpong-type communication structures for all small groups. Second, negative interactions such as 'restraint', 'command', 'complaint', and 'lack of confidence' predominantly appeared in all small groups. Third, the students in the status of out-lookers in small groups were mainly verbal interactions, such as instructing the other person, acting against the other person's actions, and expressing dissatisfaction with the attitudes and abilities of members. Therefore, teachers should guide students to use higher-level verbal interactions in their group activities in small group activities, and engage in students communication to prevent negative interactions from occurring. The teachers also need to check the level of achievement for students in the status of out-lookers in advance and guide them to participate more actively in small group activities. This study is meaningful in that it can be sued to design teaching and learning to improve students' problem solving and communication skills.

Wireless smart sensor networks (WSSNs) have been proposed by a number of researchers to evaluate the current condition of civil infrastructure, offering improved understanding of dynamic response through dense instrumentation. As focus moves from laboratory testing to full-scale implementation, the need for multi-hop communication to address issues associated with the large size of civil infrastructure and their limited radio power has become apparent. Multi-hop communication protocols allow sensors to cooperate to reliably deliver data between nodes outside of direct communication range. However, application specific requirements, such as high sampling rates, vast amounts of data to be collected, precise internodal synchronization, and reliable communication, are quite challenging to achieve with generic multi-hop communication protocols. This paper proposes two complementary reliable multi-hop communication solutions for monitoring of civil infrastructure. In the first approach, termed herein General Purpose Multi-hop (GPMH), the wide variety of communication patterns involved in structural health monitoring, particularly in decentralized implementations, are acknowledged to develop a flexible and adaptable any-to-any communication protocol. In the second approach, termed herein Single-Sink Multi-hop (SSMH), an efficient many-to-one protocol utilizing all available RF channels is designed to minimize the time required to collect the large amounts of data generated by dense arrays of sensor nodes. Both protocols adopt the Ad-hoc On-demand Distance Vector (AODV) routing protocol, which provides any-to-any routing and multi-cast capability, and supports a broad range of communication patterns. The proposed implementations refine the routing metric by considering the stability of links, exclude functionality unnecessary in mostly-static WSSNs, and integrate a reliable communication layer with the AODV protocol. These customizations have resulted in robust realizations of multi-hop reliable communication that meet the demands of structural health monitoring.
