In modern society which changes from quantity-seeking society to value-seeking one, people's various lifestyles have great effect on consumption patterns and work as an important factor in choosing hotels. The fact that design hotels, which provide unique experiences with differentiated and sensitive designs by reflecting various lifestyles, recently attract attention can be understood in the same context. As a matter of fact, design hotels recently serve as destinations as they become cultural and artistic icons which reflect customer lifestyles. Especially, the designs of lobby spaces in hotels play deciding role in customers' choices while representing the nature of hotels. In this respect, under the premise that the kinds of accumulated experiences are different depending on lifestyles and preferences for specific interior spaces are influenced by association mechanism formed by experiences, this study analyzed lobby spaces of design hotels which focus on specific lifestyles from the perspective of association mechanism based on experiences. As the method of analysis, this study classified the types of lifestyles and conducted case analysis to investigate what association mechanism works to enhance the preference of design hotels by types. Study classified lifestyles into experiential activity type, social meeting type, fashion-pursuing type and hideout-preferring type and analyzed cases of lobby designs in design hotels. The results of this case analysis are as follows; First, experiential activity type mainly utilized quasi-association and approach association through senses and social meeting type utilized quasi-association and memory association through emotions while fashion-pursuing type utilized quasi-association and presumption association through intuition and hideout-preferring type utilized quasi-association and approach association through thoughts. Second, it was found that most lobby designs are characterized by association mechanism in visual formative nature and that in temporal spatial nature working in complex way, and, through such process of association expansion, space stories are created. Stories of spaces created this way become unique identities of design hotels that provide new experiences for customers.

The problem Japanese universities face is exactly the same as that of German universities: no international recognition in world rankings of universities despite their high levels of postwar economic and technological developments. This was indeed one reason why world-class Japanese firms, such as Toyota and Sony, have avoided working closely with Japanese universities for R&D partnership and new technology commercialization. To resolve this problem, the Japanese government has continuously implemented aggressive policies of the internationalization, privatization, liberalization, and privatization of universities since the onset of the economic recession in 1989 in order to revitalize the Japanese economy through radical innovation projects between universities and firms. National projects of developing medical robots for Japan's ageing society are some of the ambitious examples that emphasize feed-forward learning in innovation. However, this paper argues that none of these programs of fostering university-firm alliances toward feed-forward learning has been successful in promoting the world ranking of Japanese universities, although they showed potentials of reinforcing their conventional strength of introducing $kaizen$ through feedback learning of tacit knowledge. It is therefore argued in this paper that Japanese universities and firms should focus on feedback learning as a way to motivate firm-university R&D alliances.

Colloidal synthesis of nanoparticles with well-controlled size, shape, and composition, together with development of in situ surface science characterization tools, such as ambient pressure X-ray photoelectron spectroscopy (APXPS), has brought new opportunities to unravel the surface structure of working catalysts. Recent studies suggest that surface oxides on transition metal nanoparticles play an important role in determining the catalytic activity of CO oxidation. In this talk, I will outline the recent studies on the influence of surface oxides on Rh, Pt, Ru and Co nanoparticles on the catalytic activity of CO oxidation [1-3]. Transition metal nanoparticle model catalysts were synthesized in the presence of poly(vinyl pyrrolidone) polymer capping agent and deposited onto a flat Si support as two-dimensional arrays using the Langmuir-Blodgett deposition technique. APXPS studies exhibited the reversible formation of surface oxides during oxidizing, reducing, and CO oxidation reaction [4]. General trend is that the smaller nanoparticles exhibit the thicker surface oxides, while the bigger ones have the thin oxide layers. Combined with the nature of surface oxides, this trend leads to the different size dependences of catalytic activity. Such in situ observations of metal nanoparticles are useful in identifying the active state of the catalysts during use and, hence, may allow for rational catalyst designs for practical applications. I will also show that the surface oxide can be engineered by using the simple surface treatment such as UV-ozone techniques, which results in changing the catalytic activity [5]. The results suggest an intriguing way to tune catalytic activity via engineering of the nanoscale surface oxide.

This study relates to meta-phenomena in architectural design. Among others, this study aims to interpret and demonstrate the cognitive thoughts and methodological systems in 'autonomy and instrumentality' presented in works of art by positivist architects focusing on diagrams after the second modernity in addition to earlier formal experiments by John Hejduk, Peter Eisenman, Bernard Tschumi, and Daniel Libeskind. In order to achieve these aims, this study approached the mimetic concepts developed by Walter Benjamin and Theodor Adorno. Especially, meta-phenomena in the methods of architectural design were connected to productivity in Adorno's mimetic concepts. Also, in terms of formation and creation of works of art, the mimetic backgrounds of Adorno's theories on aesthetics were identified from features of concepts on the part of formal experiments. The results were systemized methodologically based on meta-phenomena appearing in pure arts and overall architectural design. These were presented as a framework to interpret 'autonomy and instrumentality' that exist in the working of negativity and mimesis. In this way, logics and intuition in architectural design as well as methodological systemization of convergent creativity were proved valid. In conclusion, Adorno's mimetic concepts systemized based on negativity and critical awareness may lead to new concepts. It has been proved that it is valid for security of meta-phenomena of architectural design as a production of autonomous spaces for differences and creation.

The Buildings and facilities of municipal Councils of fundamental autonomous organization in various regions were made on the basis of its experiences in 1950s but lacked constructional sophistication and failed to comprehend their functions, resulting in several repairs and renovations after the dedications of the buildings. They also undermined the efficiencies of the worn and was a big drain on the budget of municipal councils. Furthermore, especially after the integration of rural and urban areas. Municipal councils in urban areas couldn't accommodate the increased staffs. Thereby, They used the established councils in the cities and countries and repaired and renovated other buildings of which were permitted as offices, decreasing the eligibility of the buildings for municipal councils. The poor constructional working conditions triggered new constructions of the buildings reserved only for municipal councils. The study finds out find out about the work of municipal councils and analyzes how the municipal council buildings are used as substitutional spaces, directing which way they should go in mapping out spaces. Resultantly, It becomes basic materials in constructing municipal buildings.

The number of 1 or 2 households is rapidly increasing due to the participants of women in the working society, the increment of unmarried men, and the change in family structure. The current housing market and the housing administration focuses more on the bigger number of households so that single person households are being neglected. As more individuals move to the capital, living in the city for a single person household has become very difficult. Sharing has become an important aspect among the society and shared housings have hit the minds of single person households as a new way of living. Comprehensive properties, boarding houses, housings for studying (Go-Si-Won), and officetels match the ideas of shared housings. The absent of clear standards on private rooms and shared facilities is making the living very challenging. This study aim to understand foreign (England, Australia, and Japan) institutional characteristics for shared housings to build foundations in order to bring in shared housings into Korea. The residential concept can not be applied to shared housings in Korea directly since the idea of living is different for each nation and its cultural distinctions. However, a clear classification and standards on shared housings depending on the size of the house and number of residents are needed alongside with an index of principles and residential criteria.

The visualization of three dimensional geophysical data is forcing a revolution in the way of working, and allowing the discovery and production of hydrocarbons at much lower costs than previously thought possible. There are many aspects of this revolution that are behind the scenes, such as the database structure, the storage and retrieval of data, and the exchange of data among programs. Also the user had changes where the interpreter (or manager, or processor) actually looks at and somehow interacts with the data. The use of opacity in volume rendering, and how its judicious application can assist in imaging geologic features in three dimensional seismic data. This revolutionary development of new technology is based on the philosophy of synergy of inter-disciplines of the oil industry. Group interaction fostered by large room visualization environments enables the integration of disciplines we strive for, by putting the petrophysicist, geologist, geophysicist, and reservoir engineer in one place, looking at one image together, without jargon or geography separating them. All these tools developed in the oil industry can be applied into the civil engineering industry also such as the prior geological and geophysical survey of the constructions. Many examples will show how three dimensional geophysical technology might make a revolution in the oil business industry now and in future. This change can be considered as a fusion process at data, information, and knowledge levels.

Providing web-based information literacy is a new turning point in the library instruction. After 2005 many university libraries are adopted to web-based information literacy. However as a result of research found out that initial problems of introduction to web-based information literacy are shown such as the lack of interest and motivation causing factor, the simplicity of providing method and so on. In order to maximize the effectiveness of web-based information literacy, working out in the way how to use library, how to search, demand of information, information ethics are the factors which should be constructed in the overall content aspect of web-based information literacy. Also, understanding and analysis of the tendency of users through the provision of diversity, flexibility of IT technology is based on a secure, and the need to pursue a variety of media are the factors which should be needed the way how to provide.

Information Technology (IT) has been working as an engine of growth in Korea since early 1990's. For the next leap of Korean economy and to overcome worldwide financial crisis, Korea's IT industry needs to find a new breakthrough. In this viewpoint, we tried to empirically analyze the impact of Korea's IT trade on domestic industry. Since Korean government is trying to set up a few free trade agreements (FTA) with major trade partners, more accurate understanding of the impact of FTA is required to find the correct way to promote Korea's IT industry. We first looked at the current status of Korea's IT trade with major partners such as the US, Japan, and China to understand the competitiveness of Korea's IT industry. Having done this, we measured the impact of IT trade on domestic industry using Granger causality test. The results showed that the positive impact of trade is bigger on IT industry than on whole industry. Also, the impact of import turned out to be bigger than that of export. Among the major trade partner countries, the US’s and China's impacts are bigger than Japan's impact. Another notable thing is that IT product import from the US has especially big impact on domestic IT industry. Our findings may have certain implications to the FTA related policy.

Due to the strict requirements of emerging applications, per-flow admission control is gaining increasing importance. One way to implement per-flow admission control is using an on­path resource reservation protocol, where the admission decision is made hop-by-hop after a new flow request arrives at the network boundary. The next-steps in signaling (NSIS) working group of the Internet engineering task force (IETF) is standardising such an on-path signaling protocol. One of the reservation methods considered by NSIS is reduced-state mode, which, suiting the differentiated service (DiffServ) concept, only allows per-class states in interior nodes of a domain. Although there are clear benefits of not dealing with per-flow states in interior nodes-like scalability and low complexity-, without per-flow states the handling of re-routed flows, e.g., after a failure, is a demanding and highly non-trivial task. To be applied in carrier-grade networks, the protocol needs to be resilient in this situation. In this article, we will explain the consequences of a route failover to resource reservation protocols: Severe congestion and incorrect admission decisions due to outdated reservation states. We will set requirements that handling solutions need to fulfill, and we propose extensions to reduced-state protocols accordingly. We show with a set of simulated scenarios that with the given solutions reduced-state protocols can handle re-routed flows practically as fast and robust as stateful protocols.
