Korean-Japanese architect Itami Jun that proceeded with primeval architecture based on analogue ideas in the digital era realizing nomad architecture is delivering a totally different meaning in the modern time. Not like the Japanese architectural community equipped with rich technologies showed state-of-the-art architecture after 1980s, Itami Jun' formative consciousness intending to assimilate nature from the original position of things is thought to have started from the relationship with Korean-Japanese painters leading MONO-HA desiring to look at the world as it is and approach the source of existence. The purpose of this study is to analyze the spatial characteristics from the viewpoint of 'Theory of Meeting' which is the essence of the work theory of Lee UFan that made the theoretical foundation of MONO-HA to understand Itami Jun's architectural space in the ideological aspect. Although the characteristics of marginal men appearing in Itami Jun's architectural space as others located on the boundary between Korea and Japan, art and architecture, and functions are valuable research objects, they have not been studied in the aspect of source, so it is needed to research his works and the source of the spatial ideas that led his works. Based on Theory of Meeting claiming that the world becomes the place of experience by the medium of objet which is the structure of meeting, and that human beings can meet the truly opened world by self-awareness through body, the expressive characteristics of Itami Jun's interior space was analyzed. As a result of the analysis, it turned out that Itami Jun's interior space actively expressed Theory of Meeting on the unity of structure and space, and on the trans-boundary by the medium of objet. Conclusively, this study suggests that, in the reality of the modern interior design full of technology-intensive designs, analogue approach moving in the opposite way from technologies could be a better expressive method of design delivering the fundamental human emotions.

In this research, a case study for cooperative learning practiced in a design class for environmental engineering was presented. Designing a treatment facility for urban diffuse pollution was a main problem given to the participants. Turn-key system for civil works were simulated throughout class works. Twenty five students were grouped into four virtual companies and assigned own position from chairperson to workers. Each group competed throughout establishing design concept regarding order, expense calculation, process distribution, actual calculation. Best design with lowest bidding won the first place. For evaluating class effectiveness, one student from each group were monitored thorough semester. Participants were improved for their understanding about company establishment, turn-key system management, awareness about personal management, and presentation skills. Tension of the class was effectively elevated as well.

Visual demands associated with in-vehicle display usage and text messaging distract a driver's visual attention from the roadway. To minimize eyes-off-the-road demands, voice interaction systems are widely introduced. Under cognitively distracted condition, however, awareness of the operating environment will be degraded although the driver remains oriented to the roadway. It is also know that the risk of inattentive driving varies with age, thus systematic analysis of driving risks is required for the older drivers. This paper aims to understand the age-related driving performance degradation and visual attention changes under auditory cognitive demand which consists of three graded levels of cognitive complexity. In this study, two groups, aged 25-35 and 60-69, engaged in a delayed auditory recall task, so called N-back task, while driving a simulated highway. Comparisons of younger and older drivers' driving performance including mean speed, speed variability and standard deviation of lane position, and gaze dispersion changes, which consist of x-axis and y-axis of visual attention, were conducted. As a result, it was observed that gaze dispersion decreased with each level of demand, demonstrating that these indices can correctly rank order cognitive workload. Moreover, gaze dispersion change patterns were quite consistent in younger and older age groups. Effects were also observed on driving performance measures, but they were subtle, nonlinear, and did not effectively differentiate the levels of cognitive workload.

Photovoltaic (PV) module can generate electricity using sunlight without causing any environmental degradation. Due to higher fossil fuel prices and environmental awareness, PV applications are becoming more popular as clean source of electricity generation. PV output is sensitive to the operating temperature and can be drastically affected in Building Integrated PV (BIPV) systems. PV Solarwall (SWPV) combination and PV systems have been evaluated in this study for improvement in electrical output and system costs. PV modules under forced ventilation. A 75W polycrystalline silicon PV module was fixed on SW in front of the ventilation fan as it was indicated to be the coolest position on the SW in phoenix simulations. The effectiveness of cooling by means of the forced ventilating air stream has been studied experimentally. The results indicate that there appears to be significant difference in temperature as well as electricity output comparing the SWPV and BIPV options. Electrical output power recovered is about $4\%$ during the typical day of the month of February. RETScreen(R) analysis of a 3kW PV system hypothetically located at Taegu has shown that with typical temperature reduction of $15^{{\circ}C$, it is possible to reduce the simple payback periods by one year. The work described in this paper may be viewed as an appraisal of a SWPV system based on its improved electrical and financial performances due to its ability to operate at relatively lower temperatures.

In this paper, we developed a system that could assist appropriate activities for medication compliancy of the elderly. It employs a proactive knowledge which is represented as XML templates predefined for their medication activities. The knowledge-based assistance depends on the contexts considerably, which the system can recognize by continuously monitoring the current position and the time-schedule for their medications. The monitoring can be performed with ultrasonic sensors and infrared sensors mounted in a display and a pillbox respectively. According to the recognized contexts, the medication activities required by the elderly can be serviced through user-friendly multimedia display. In special, our experiment evaluates that the developed system is able to enhance the medication compliancy of chronic disease patients.

The distinction between isolated and combined injuries is crucial both for treatment and prognosis. For most combined injuries, surgical treatment continues to be favored over nonoperative treatment. It is generally agreed that isolatel PCL injuries do well without surgery. There has been an interest by many authors to fix the graft directly to the posterior aspect of the tibia(tibial inlay). With this procedure, tibial graft fixation will be more direct and theoretically reduce the bending effects of the graft with a fixation site far away from the tibial insertion. Modified tibial inlay technique, which is the posterior approach does not require the patient to be in the prone or lateral decubitus position during the operation. Use of a double-bundle reconstructive technique is attractive and has been performed by some surgeons. At this time, this procedure is still being investigated and should not be routinely used in the clinical setting until studies have indicated an advantage over current single-bundle techniques. However theologically, double-bundle reconstructive technique is more useful in severe posterior unstable knee. Recent advances have increased our knowledge of the anatomy and mechanical characteristics of the PCL. Basic science research has further increased our awareness of the interaction of the posterolateral structures with the PCL. To achieve restoration of normal posterior laxity, it is critical to address the posterior as well as the postero-lateral structures. Surgical treatment is often complex and requires a wide range of surgical techniques and skills to treat associated injuries. When the PCL is reconstructed, most surgeons choose to reconstruct the anterolateral component using a graft of sufficient size and strength. The initial postoperative rehabilitation should be addressed cautiously in an effort to avoid excessive forces on delicate repairs and reconstructions in these complex injuries. Further research is necessary to evaluate new surgical approaches such as double-bundle reconstructions and tibial inlay techniques as well as improved techniques for capsular and collateral ligament injuries.

MANET(Mobile Ad-hoc Network) has been proposed as a infrastructure-less network using distributed algorithm for remote environment monitoring and control. The mobility of MANET would make the topology change frequently compared with a static network and a node is resource-constrained. Hence, to improve the routing protocol in MANET, energy efficient routing protocol is required as well as considering the mobility would be needed. In this paper, we extend RODMRP(Resilient Ontology-based Dynamic Multicast Routing Protocol) structure by a modifying the level of cluster. We call this network protocol CACH-RODMRP. Our contribution consists estimating the optimal level of clustering depth with considering node position and reducing the network residual energy. The simulation results of proposal algorithm show that the energy is significantly reduced compared with the previous clustering based routing algorithm for the MANET.

In the 21st century, boundary between different fields is coming down, convergence and consilience are taking place. It would not be an exaggeration to say key buzzword of the 21st century is 'convergence'. Also in the field of art and design, the border between the two areas is getting more ambiguous. With the reason, both the new awareness and interest on Art Furniture are becoming more heightened. So far as part of the decorative art category Art Furniture was covered. However Art Furniture is now no longer a fixture of that field, but became independent as a new genre of art. As proof of this, at the international representative art fairs including the Design Miami, PAD London, and The Salon of Art and Design which was recently established in New York, etc. Art Furniture is becoming a showcase as the main pieces. Moreover, at the world's major art market Sotheby's, Christie's, and Seoul Auction, Art Furniture's position is more successfully becoming extended. At this point the analysis of the status and the cause on the non-boundary phenomena between art and design is inevitably required to understand the disposition of the public and to develop the domestic furniture industry. Thus, this paper purposes to present the new direction for that the domestic Art Furniture encompasses the two areas with satisfaction to the demands of the public by studying on the non-boundary phenomena between art and design in contemporary Art Furniture.
