The purpose of this study is to analyze the characteristics of the non-sedentary in contemporary multi-housing planning through the understanding and interpretation of the modern nomadic life. A document research method was used to analyze and classified the spatial characteristics and development of the non-sedentary dwelling spaces since 1980. Finally, today the applicable cases of non-sedentary space are as follows; the sharing housing, the adapting housing, and temporary housing for the multi-purpose spaces, huge spaces and the industrialization housing. First of all, in order to conform the concept of nomadism, the theory and characteristics were divided into three aspects; The concept of thought of lines, events and Rhisome, and the spatial characteristics of fluidity, multiplicity and the non-hierarchy, that is mainly based on the philosophy of Gilles Deleuze. This study attempted to analyze how the concept of non-sedentary dwelling space has been developed in what form and method they have been applied and interpreted in the historical background. It attempted to resolve the concept of movement and mobility through the experiment so that they might apply to the space of contemporary city.

Background: Previous researchers have investigated the mechanical and neurophysiological effects of manual mobilization, however little research has been done on muscle tone and muscle stiffness. Objective: To compare the effects of posterior-anterior (PA) mobilization with weight bearing on sling and conventional PA mobilization on the bed. Design: Randomized controlled trial (single blind) Methods: The subjects were 16 male university students and randomized to sling mobilization group (SMG, n=8) or conventional mobilization group (CMG, n=8). SMG received PA mobilization using a sling and CMG received traditional mobilization on the bed during lumbar mobilization. Results: Both left and right muscle tones of SMG increased, but left muscle tone of SMG were increased and right muscle tone was decreased after intervention. In addition, both left and right muscle stiffness of SMG were also increased, however left muscle stiffness of SMG was increased and right muscle stiffness was decreased. The muscle tone and muscle stiffness of SMG were higher than those of DMG, especially the right side was statistically significantly higher. Extension of SMG, extension and flexion of CMG were increased statistically significantly except for Flexion of SMG (p<.05). There were no significant differences between the groups in Extension and Flexion. Conclusions: This study suggests that lumbar spine PA mobilization using sling is beneficial in improving muscle tone, muscle stiffness, and trunk movement.

Mobile IPv6 spends considerable bandwidth considering that its signal volume is proportional to the mobile and also it should be strengthened to support the binding signal volume, the traffic, and effective mobility. So, the study in NEMO(Network Mobility), an extended version of Mobile IPv6, has been conducted. NEMO provides its mobility by putting several mobiles and more than one portable router into one unit called as mobile network. Because nodes access Internet via the portable router at this time, it receives transparency without any additional work and that much reduces binding signal while solving binding storm. By supporting mobility, NEMO is able to have various mobile structures which realize several networks hierarchically and it is necessary to improve its safety and security by authenticating among the upper networks or the lower ones while moving. Also, it is extremely required to begin a study in the device to improve efficiency accompanied with mobility, which is executed by the fast hand-off as well as the safe authentication. For those reasons, this paper not only classifies various NEMO mobile scenarios into 7 ways, but also provides AAA authentication of each scenario, the authentication through the safety authentication and fast handoff authentication using F+HMIPv6 and the way to reduce both signaling volume and packet delays efficiently during the handoff.

Constructivism is an avant-garde movement that began in 20th-century Russia, which rapidly turned into an industrial society. This was one of the most experimental art movements, that wanted to be at the center of social and political-ideological change as it pursued a unique style, which portrayed the true essence of art and humanity. Russian constructivism greatly influenced modern fashion and suggested a new artistic standard. First, the artistic elements of Russian constructivism include photo montages, geometrical structures, color abstraction, and an asymmetrical order, through which the ideals of the Russian Revolution were substantiated, idealized, and materialized into an artistic form. Second, the different forms of Russian constructivism have various artistic characteristics such as popularity, spatiality, structuralism, decorativeness, and mobility, which were then expressed in modern fashion elaborated below. This study intends to reconstruct the meaning of Russian formalism and reflect it on fashion; thereby reconsidering the characteristics and the meaning of Russian constructivism in the context of today's fashion. This will broaden the meaning of constructivism and suggest a new direction for modern fashion.

"Dynamic stabilization" systems have been developed in recent years to treat degenerative disorders of the spinal column. In contrast to arthrodesis (fusion), the aim here is to conserve intervertebral mobility to maximize comfort. When developing innovative concepts, many mechanical tests need to be carried out in order to validate the different technological solutions. The present study focuses on the B Dyn$^{(R)}$ "dynamic stabilization" device (S14$^{(R)}$ Implants, Pessac, France), the aim being to optimize the choice of polymer material used for one of the implant's components. The device allows mobility but also limit the range of movement. The stiffness of the ring remains a key design factor, which has to be optimized. Phase one consisted of static tests on the implant, as a result of which a polyurethane (PU) was selected, material no.2 of the five elastomers tested. In phase two, dynamic tests were carried out. The fatigue resistance of the B Dyn$^{(R)}$ system was tested over five million cycles with the properties of the polymer elements being measured using dynamic mechanical analysis (DMA) after every million cycles. This analysis demonstrated changes in stiffness and in the damping factor which guided the choice of elastomer for the B Dyn$^{(R)}$ implant.

In recent years, capsule endoscope is highlighted for the patient's convenience and the possibility of the application in the small intestine. However, the capsule endoscope has some limitations to get the image of the digestive organ because its movement only depends on the peristaltic motion. In order to solve these problems, locomotion of capsule endoscope is necessary. In this paper, we analyze the locomotive mechanism of earthworm-like robot proposed as locomotive device of capsule endoscope and derive the condition which can Judge the possibility of its mobility using theoretical analysis. Based on a biomechanical modeling and simulation, the critical stroke, that is minimum stroke of the earthworm-like robot to perform motion inside small intestine, is obtained. Also, this derived critical stroke can be validated by the moving test of fabricated earthworm-like robot. Consequently, it is expected that this study can supply useful information to design of earthworm-like robot for mobility of capsule endoscope.

The development of USN(Ubiquitous Sensor Network) technology is creating numerous application areas. Although a network configuration with fixed sensors was the norm in the past, the coexistence of mobile and fixed sensor nodes is a new trend. Fixed sensor networks focused on the energy efficiency of nodes, but the latest studies consider guaranteeing the mobility of nodes and maintaining their connectivity, while remaining energy efficient at the same time. This paper proposes a routing protocol for a mobile ad-hoc sensor network that improves the mobility, connectivity and energy efficiency of nodes while allowing for the management and maintenance of a large number of nodes even in a complex communication environment where mobile and fixed nodes coexist. An algorithm for multi-hop multi-paths, a technique for topology reconfiguration by node movement prediction and vibration sensors, path setting for a large number of nodes, and efficient data transfer technology have been introduced to implement the modified LEAHC-AOMDV protocol. Furthermore, the excellence of this protocol was verified through a comparative experiment with the conventional LEACH protocol.

Vehicular Ad Hoc Networks (VANETs) are self-configuring networks where the nodes are vehicles equipped with wireless communication technologies. In such networks, limitation of signal coverage and fast topology changes impose difficulties to the proper functioning of the routing protocols. Traditional Mobile Ad Hoc Networks (MANET) routing protocols lose their performance, when communicating between vehicles, compromising information exchange. Obviously, most applications critically rely on routing protocols. Thus, in this work, we propose a methodology for investigating the performance of well-established protocols for MANETs in the VANET arena and, at the same time, we introduce a routing protocol, called Genetic Network Protocol (G-NET). It is based in part on Dynamic Source Routing Protocol (DSR) and on the use of Genetic Algorithms (GAs) for maintenance and route optimization. As G-NET update routes periodically, this work investigates its performance compared to DSR and Ad Hoc on demand Distance Vector (AODV). For more realistic simulation of vehicle movement in urban environments, an analysis was performed by using the VanetMobiSim mobility generator and the Network Simulator (NS-3). Experiments were conducted with different number of vehicles and the results show that, despite the increased routing overhead with respect to DSR, G-NET is better than AODV and provides comparable data delivery rate to the other protocols in the analyzed scenarios.

In NEMO scenarios, mobile node's variety of movements and mobile router's point of attachment changes can result in handover. This handover process needs additional time to finish due to the multiple levels of indirection involved in NEMO. And the performance issues of mobile node's handover such as handover delay and packet loss in above cases haven't been studied thoroughly. So, in this paper, we define fast handover failure cases in hierarchical mobile IPv6 network based NEMO. We briefly described NEMO architecture and handover procedures of FMIPv6 and HMIPv6. And then, we classified mobile node or mobile router's movement pattern into several scenarios. Analysis for the fast handover classified NEMO scenarios, in terms of handover latency and packet delivery cost have been performed.
