The purpose of this study is to review the mobility-based textual research methods raised in Mobility and Foucault and apply them to textual analysis. This book contains seven articles applying Foucault's terms to mobility studies, giving intellectual stimulation to both studies. Since Foucault examined discipline power operated through the technology of distinguishing between rational/irrational and normal/abnormal, his works seem to a study of closed spaces like prisons. However, the authors of this book note that Foucault's works already had sufficient insight on mobility, and them actively incorporated it into mobility study. When we concentrate Foucault's works on mobility as a governmentality and a dispositif, the tension and dynamics between mobility and immobility are emphasized. And then it is possible to cross the simple dichotomy in mobility studies. This paper analyzes Kim Joong-hyuk's short story 1F/B1 by applying this method. This story describes a building manager who seems to be fixed in a building, but the mobility of him in the story goes through stereotypes and creates new spaces. Kim Hye-jin's short stories also represent mobility that cannot move and hesitates. These stories are important in that they show the mobility as a dispositif that constitutes the subject. When referring to the achievements of Mobility and Foucault, we read this narrative again by paying attention to the dynamics of mobility and immobility in the text. The significance of this paper is that it expands mobility-based textual research anew. While text analysis applying mobility study was usually focused on clearly mobile narratives such as travel statements and diaspora narratives, Mobility and Foucault drives new textual research by paying attention to the relationship between power and mobility, mobility and immobility dynamics. Therefore, this paper is significant in confirming the new meaning of the text revealed when paying attention to the representation of mobility in the narrative that no one seems to be mobile, and seeking to expand the mobility-based textual research method.

Many researchers have been carrying on study to figure out the exact collision efficiency between bubble and floc. Collision efficiency can has generally been quantified by using trajectory analysis which uses the hydrodynamic, the electrostatic and van der waals forces. Two types of method are considered to induce the hydrodynamic force in the trajectory analysis. One is to use stream function and the other is to use mobility function. There was some difference between stream and mobility function depending upon modelling factors and conditions in trajectory analysis.

The mobility is one of the most important factor for mobile IPTV. However, mobility is highly vulnerable to eavesdropping and unauthorized access. Generally mobility of mobile services is based on handover techniques. But we showed that mobile IPTV must use other techniques to confirm mobility. In this paper, we analyzed security of wibro mobile IPTV from the viewpoint of mobility. We considered DCAS host must include new addresses of mobile devices. We analyzed total number of authentication for the proposed method. So we showed that proposed method was more efficient than wibro-mobile IPTV. We compared the security of our proposal to the security requirements of TTA.

As the applications for Mobile Ad-hoc NETworks (MANETs) have varied, performance analysis has become one of the main research areas. They commonly offer only simple radio propagation models that neglect obstacles of a propagation environment. The radio wave propagation model has a strong impact on the results of the simulation run. In this paper we present the new experimental results of the impacts of the various propagation models on MANETs' performance. Intensive simulations have been presented using the group mobility which models typical ad-hoc situations such as military movements or disaster recovery activities under the supervision of a group leader. Comparisons of conventional simple models with more complicated models, i.e., shadowing, Raleigh, and Ricean models, show that, in spite of the models' popularity, the free space and two-ray ground models are too optimistic in describing real ad-hoc group mobility situations.

A wheel chair lift can be useful to make a social integration by expanding the economical and cultural activities through enhancing the mobile areas for the mobility handicapped. This research is about the guide when designing a wheel chair lift which extracted demands of wheel chair riders by the new paradigm of the high-speed railroad and social integration by securing the mobile areas and analysis on the user. Also the basic size was extracted to be applied to the design through analysis on the outer size of wheel chairs and researches on their mobility. The wheel chair lift design guideline was offered by reviewing the current law on wheel chair lifts.

In this paper, mobility of planar mobile robots is discussed. Firstly, simplified joint models for four typical wheels of the mobile robots are described including both rotational and translational friction parameters. Then, based on these joint models and through the inclusion of the additional imaginary joint particularly to the mobile robots which lack geometric generality, mobility analysis of various types of planar mobile robots is performed.

In this paper, we define the multi-states exponential cell resident time mobility model for describing the mobility characteristics of mobile user and analyzed the total cost of the hybrid method using multi-states cell resident time. Generally, the mobile user has three states for its movement, such as staying, walking and driving. This multi-states cell resident time based hybrid method reflects the movement characteristics of mobile user and adapts the location update period according to the states of mobility speed. As a results of the performance analysis, we can get the optimum parameters of the hybrid method for multi-states based mobile users.

Objective : The objective of this study was to explore the meaning of Mai (脉) in the fifteen letters provisions of Gangpyeong-Shanghanlun through the comparative analysis of 10 cases and paleography. Methods : We have collected 10 cases that have been diagnosed and treated by Gangpyeong-Shanghanlun Mai (脉) provision. And then, comparative analysis has been done among those 10 cases. Based on result of case analysis, paleographic meaning of each Mai (脉) have been studied to redefine Gangpyeong-Shanghanlun Mai (脉)'s meaning. Results : After administration of Mai (脉) provision's herbal medicine, all 10 patients recovered their mobility problem and pain. From this result, we could fomulate the hypothesis that Mai (脉) in Gangpyeong-Shanghanlun could mean mobility problems. After through further paleography studies, we could elaborate each Mai (脉)'s clinical meaning and related diseases. Conclusions : Mai (脉) in Gangpyeong-Shanghanlun could mean mobility problems caused by various diseases, which include musculoskeletal pain, neuropathy, syncope, fatigue, developmental disability and major depressive disorder.

Cost-effective mobility management for the roaming mobile users is very important in the seamless services on next-generation wireless network (NGWN). MIPv6 (Mobile IPv6) is one of the mobility management schemes proposed by the IETF (The Internet Engineering Task Force) and various IPv6-based mobility management schemes have been developed. They are directly involved with data transfer from MN (Mobile Node). In this paper, two kinds of schemes in analyzing of mobility management schemes are proposed. The signaling transfer and packet delivery procedures for each mobility management schemes are analyzed, respectively. The signaling cost for mobility management schemes are calculated, and the cost of each protocol are analyzed numerically. In other word, applying the sum of signaling cost and packet delivery cost to each mobility management scheme, their costs are analyzed. Finally, our performance evaluation results that the network-based mobility management scheme shows better performance in terms of overall cost.
