Bilbao, Spain, made a mark as a example of the regional revitalization by culture and tourism. Korean Government have a perspective that culture and tourism could be an alternative to the regional crisis of manufacturing in 2018. The main purpose of this study is to analyze the locational specificity and the revival strategies for the regional development of Bilbao in a structural context. This could provide implications to the regional crisis of Korea. The main results are summarized as follows. Firstly, the local government of Bilbao has taken an active role, using not only its political and financial autonomy but also its locational advantage as an important nodal region of transnational trade networks in Europe. Secondly, Bilbao was able to sustain its regional revitalization initiatives for a long period by facilitating public-private partnership system. Finally, despite the effectiveness of the mega project and place marketing, low job security and the polarization of the service sector have emerged as a problem at the same time. Still, the deindustrialization of Bilbao could be possible due to the various services including knowledge-based services and financial services as well as culture and tourism.

The idea that city culture can be employed as a driver for urban development has become part of the new orthodoxy by which cities seek to enhance their competitive position. Such development reflect not only the rise to prominence of the cultural sphere in the city development, but also how the meaning of culture has been refined to include new uses in order to meet the main objectives of sustainable development. This study focuses on the procedure how the cultural infrastructure and historical context can be applied for urban regeneration strategy. Two successful cases (Bilbao, Spain and Yokohama, Japan) were selected for analysis of strategies as a whole, background, main characteristics of culture-led urban regeneration strategies and their effect for urban regeneration have been analyzed in detail. In conclusion, lessons for the future development were suggested in terms of resources, planning and linking strategies.

In the aeronautical environment, numerous regulatory and communication protocols exist that cover interconnection of on-board equipment inside the aircraft. Developed and implemented by the airlines since the 1960s, these communication systems are reliable, strong, certified and able to contact different sensors distributed throughout the aircraft. However, the scenario is slightly different in the structural health monitoring (SHM) field as the requirements and specifications that a global SHM communication system must fulfill are distinct. The number of SHM sensors installed in the aircraft rises into the thousands, and it is impossible to maintain all of the SHM sensors in operation simultaneously because the overall power consumption would be of thousands of Watts. This design of a new communication system must consider aspects as management of the electrical power supply, topology of the network for thousands of nodes, sampling frequency for SHM analysis, data rates, selected real-time considerations, and total cable weight. The goal of the research presented in this paper is to describe and present a possible integration scheme for the large number of SHM sensors installed on-board an aircraft with low power consumption. This paper presents a new communications system for SHM sensors known as the Bi-Instruction Link Bi-Operator (BILBO).

Researchers have made significant progress in recent years towards realizing effective structural health monitoring (SHM) utilizing wireless smart sensor networks (WSSNs). These efforts have focused on improving the performance and robustness of such networks to achieve high quality data acquisition and distributed, in-network processing. One of the primary challenges still facing the use of smart sensors for long-term monitoring deployments is their limited power resources. Periodically accessing the sensor nodes to change batteries is not feasible or economical in many deployment cases. While energy harvesting techniques show promise for prolonging unattended network life, low power design and operation are still critically important. This research presents the WiSeMote: a new, fully integrated ultra-low power wireless smart sensor node and a flexible base station, both designed for long-term SHM deployments. The power consumption of the sensor nodes and base station has been minimized through careful hardware selection and the implementation of power-aware network software, without sacrificing flexibility and functionality.

Many cities are utilizing their cultural capital as a means for urban regeneration and tourist attraction. Museums form an essential component in these culture-based urban regeneration efforts, the Guggenheim Bilbao being a frequently cited example of success. The United Arab Emirates (UAE) has benchmarked the Bilbao case study as they were looking for alternative income-generating industries in the post-oil era, embarking on a city-building project on the Saadiyat Island where resorts and cultural institutions of massive scale are being constructed. The Louvre Abu Dhabi and the Guggenheim Abu Dhabi were pursued under this scheme, aiming at attracting tourism and elevating their status in the region as a cultural capital. This study examines the political, economic, and cultural background behind the Saadiyat city project and the pending issues behind the construction of the Guggenheim Abu Dhabi. This study purports that besides funding and an ambitious plan, social and cultural developments in the region over time will be essential for a successful localization of a Western brand museum in the region.

A study has been carried out of the regenerability of a commercial Ni catalyst used in the steam reforming of the volatiles from biomass pyrolysis (gases and bio-oil), determining the evolution of the reaction indices (conversion, product yields and $H_2$ production) in successive reaction-regeneration cycles. The causes of catalyst deactivation (coke deposition and Ni sintering) have been ascertained characterizing the deactivated and regenerated catalysts by TPO, TEM, TPR and XRD. Catalyst activity is not fully recovered by coke combustion in the first cycles due to the irreversible deactivation by Ni sintering, but the catalyst reaches a pseudo-stable state beyond the fourth cycle, reproducing its behaviour in subsequent cycles.

The line of demarcation separating architecture from the art in recent years has blurred, due to the expantionist aspects between. This is a study of the direction which contemporary architecture and art are now taking. The results of the study are as follows: 1. The direction of contemporary architecture is revealed through the works of deconstructivist architects and Hans Hollein. Deconstructivist architects have incooperated abstract forms and concepts for their expression. Also Hans Hollein has brought a new aspect to architecture by combining the aura of spirituality and the use of collage. 2. The direction of contemporary art is revealed through the works of installation artists. Daniel Buren works on the interactivity between the object and the observer. Dan Graham deals with the social issues which caused by the interrelation between the eyes and the visual media. Jae-en Choi works on the actual architectural site and space capturing the spirit of what the space is for shile Jung-hwa Jung deals with the layers of perception within a particular space. Another realm coming into being is the cooperation between artists and architects. The cooperation of Holl and Acconci is expressed through their joint project Storefront Gallery. It is the development of Accocis concept of boundary and Holls methodology. Another example of this realm is revealed through the Fish Gallery of the Guggenheim Museum Bilbao. Gehry was introduced to the nature of material by Serra and Serra learned of new ways of viewing the existence of space between materials from Gehry. These new relationships between contemporary architecture and art are reciprocal in nature are indicators of a dynamic and new changing cooperation now emerging.

Today, people are bombarded with information, high-technology and multimedia. With that in mind, museum can no longer attract visitor with traditional concept, so it must find some solution or stimulation to attract their attention back. New museum is becoming a experimental space for new culture, new education, and most of all a place to fulfill one's satisfaction of life. Over the past centuries, Guggenheim Foundation has done a great job in providing place for art and place to get emotional stimulation. Out of all of their museums, Frank L. Wright's Solomon R. Guggenheim in New York and frank O. Gehry's Guggenheim Museum in Bilbao had most unique character yet share similar feature to be recognized as the architectural landmark of the 20th & 21st century Although there are close to 50 years of gap between two museums, their unique, attractive, site-specific, emotional value comes from the two most innovative architect of the past and present century. For Wright the Guggenheim was his last project but it had one of the greatest impact on his career and for Gehry the museum gave him confidence that anything is possible. This study will focus on the spatial organization as well as the architectural formation of both museum to compare and analyze. The goal of the research is to give fundamental data which will reveal emotional elements as well as concepts from each work. The content of this research will mainly focused on their architectural philosophy and it will reveal their concept on human emotion as well as the characteristics of the spatial organization. The result of the study will be a valuable reference for people designing art & cultural facilities in the future.

PURPOSE. The purpose of this study is to assess the accuracy of three intraoral scanners along the complete dental arch and evaluate the feasibility of the assessment methodology for further in vivo analysis. MATERIALS AND METHODS. A specific measurement pattern was fabricated and measured using a coordinate measuring machine for the assessment of control distances and angles. Afterwards, the pattern was placed and fixed in replica of an upper jaw for their subsequent scans (10 times) using 3 intraoral scanners, namely iTero Element1, Trios 3, and True Definition. 4 reference distances and 5 angles were measured and compared with the controls. Trueness and precision were assessed for each IOS: trueness, as the deviation of the measures from the control ones, while precision, as the dispersion of measurements in each reference parameter. These measurements were carried out using software for analyzing 3-dimensional data. Data analysis software was used for statistical and measurements analysis (α=.05). RESULTS. Significant differences (P<.05) were found depending on the intraoral scanner used. Best trueness values were achieved with iTero Element1 (mean from 10 ± 7 ㎛ to 91 ± 63 ㎛) while the worst values were obtained with Trios3 (mean from 42 ± 23 ㎛ to 174 ± 77 ㎛). Trueness analysis in angle measurements, as well as precision analysis, did not show conclusive results. CONCLUSION. iTero Element1 was more accurate than the current versions of Trios3 and True Definition. Importantly, the proposed methodology is considered reliable for analyzing accuracy in any dental arch length and valid for assessing both trueness and precision in an in vivo study.
