As the generation capacity of floating offshore wind turbines increases, the wind load applied to each turbine increases. Due to such a high wind load, the capacity of transport equipment (such as tugboats or cranes) required in the transportation and installation phases must be much larger than that of previous small-capacity wind power generation systems. However, for such an important wind load prediction method, the simple formula proposed by the classification society is generally used, and prediction through wind tunnel tests or Computational Fluid Dynamics (CFD) is rarely used, especially for a concept or initial design stages. In this study, the wind load of a 10 MW class floating offshore wind turbine was predicted by a simplified formula and compared with results of wind tunnel tests. In addition, the wind load coefficients at each stage of fabrication, transportation, and installation are presented so that it can be used during a concept or initial design stages for similar floating offshore wind turbines.

This study attempted to understand current status of overseas virtual fashion brands and analyze attributes of common digital fashion brands. Based on brand analysis criteria of previous studies, digital fashion brands were analyzed for brand concept, price range, characteristic elements, and attributes. Digital fashion design elements of items, colors, materials, patterns, and effects were analyzed by collecting images of brands' digital fashion design products. Digital fashion brands could be divided into experimental and creative digital fashion brands and digital fashion brands aiming for popular brands. This study introduces a creative fashion collection that experiments sustainability and future value. It shares a new way of self-expression and a playful culture centered on the younger generation. In terms of fashion design elements, fashion items were similar to the existing fashion category, but included other accessories that reflected the lifestyle of Generation Z. Silhouette expressed a minimalistic futuristic image centered on straight silhouettes. Color showed a bold and modern color image through black and color contrast. Unique patterns reflecting the concept of the brand appeared, centering on abstract and geometric patterns. Regarding materials and effects, new elements differentiated from existing fashion design area, showing meaningful characteristics. Digital materials are developed and proposed for sustainability. Materials (such as metal, glass, plastic) and effects (such as weightlessness, flames) expand impossible senses in reality and enable new fashion experiences. This is a case study of digital fashion brands. It is meaningful in that it identifies characteristics and discusses their values and meanings.

I.M. Pei, 2nd generation Chinese immigrant to America, has been one of the most recognized architects who designs museum architecture through out the world for completing significant projects such as the East Building of National Gallery of Art(1068-78) as well as Le Grand Louvre Renovation(1983-89) to name a few. His museum architecture, in particular, reveals his detailed consideration on viewer's artistic experience by providing well balanced architecture design to support exhibiting objects while showing his sensitivity on overall functionality of space. In recent projects such as Miho Museum in Japan, Suzhou Museum of China, and Museum of Islamic Art of Qatar, reveals his growing interests in considering "local context" in museum architecture. Therefore, the purpose of this study is focused on analyzing I.M. Pei's three museum projects having its concept focused on local context. Through out the paper, above mentioned museums were analyzed and compared to summarize his design characters and concept including site plan, spatial organization and architectural form. As a result, it is evident that I.M. Pei had put full effort to apply oriental context with modernism through out his museums. In particular, his site plan, spatial organization, and architectural form shows visible connection to comply with nature which is fundamental idea in oriental philosophy. While his basic design philosophy has been borrowed from the tradition, his ultimate design concept shows nature friendliness as well as theoretical system of thoughts and emotion and most of all, his design excellency in representing local context.

The aim of this study to examine the Hip-Hop style, one of the fashion trends of the new generation in the 1990s and to come up with a design with a Hip-Hop image. As the Counterculture, Black Renaissance, Pop Star Syndrome, the importance of Hip-Hop fashion in mass culture was recognized and given a firm place as one of the major cultural trends of the 1990s. Hip-Hop fashion has a history: it originated from the Caribbean style in the 1940s and was transformed into Rude Boys style in the 1960s, Two-tone style and Rastafarians style in the 1970s. Finally it was succeeded by B-boys and Flygirls style. Hip-Hop style combines characteristics of all three styles mixed in one, which are as follows. First, Neo-Hip-Hop Fashion, Second, Hip-Hop Reggae Fashion and Third, Graffiti Fashion. Based on these three Hip-Hop images of the 19905, an attempt will be made to produce a Design Planning with a predicted 1998 fashion trend. This research provides order sheets on ready-made clothes designed for new generation in their late 10s and early 20s. Design Concept, Image Map, Fabric, color direction will be offered on the basis of an image map drawn in line with the three design concepts incorporating three sub themes of Liveliness, Modern Ethnic, and Dynamic Future. Three designs will be designed based on the following fashion themes$\ddot{o}$ Generation 'Y', Black Guys and Street Boys.

This paper is intended as an opening of a dialog on how to apply platform thinking in the development of innovation environments. It will briefly describe a new STP (Science and Technology Park) concept called 3GSP (Third Generation Science Park), which is gaining momentum in Finland. The paper explains the fundamental changes that are currently taking place in the global innovation environment and explains why platform thinking is becoming an essential element in ecosystem development. The theoretical background and classifications of platforms are described and the benefits to be gained from STP perspective are highlighted. The paper emphasizes especially the role of so called 'competence platforms' and explains the main characteristics of a fully working competence platform. The role of competence platforms in understanding serendipity and as a fundamental factor in building the team is also highlighted. The paper analyses from STP perspective several practical examples, where platform thinking supports the emergence of new innovation environments, including Urban Mill (Finland) and Meetberlage (Netherlands). The requirements for comprehensive competence platform services are presented and their potential to support community building and therefore ecosystem development is illustrated. This analysis will provide STP practitioners with new models for applying platform thinking and will help to establish co-creation, open innovation and serendipity management practices. The case studies presented will help STP management teams to evaluate the benefits of competence platforms in different contexts.

Vibrations at different frequencies with a different intensity as well as a pressure pulsation with different parameters are two phenomena which can be observed at different water turbines. Due to the vibration and the pressure pulsation some restrictions of water turbine operation range are applied. Similar problems with the efficiency level in a wide water turbine operation range are the basic problems which are solved for ages. A theoretical and practical solution of the above mentioned problems is very much time and money consuming. The paper describes a new theoretical solution of the excitation and pressure pulsation decrease as well as extension of the operational range with high efficiency level. The new concept to decrease the vibrations and pressure pulsations is based on a heterogeneous runner blade geometry generation. The new concept of the runner geometry design was numerically tested at a low specific speed pump turbine, see Fig. 1, and basic points of the concept are presented in this paper.

The depth, width and alignment of fairway that are main port water facilities should be designed considering the various elements including particulars of design ships, weather and sea conditions around fairway and method of ship-handling. However not only the existing Japanese design standard for fairway and also those of other countries do not take into consideration of such kind of elements and no design standard is made by quantitative analysis. In this circumstance the new design standard (Approach Channels, A Guide for Design) depending on classified various elements and quantitative analysis was proposed in 1997 by PIANC and IAPH. But it was proved that calculated values according to this standard were unfounded and had some problems to output the discontinuous value by small difference of calculation condition because the each value fur each element was simply added. And also it is hard to apply this standard to the design of port water facilities in Japan because this [A Guide for Design] is the design standard for long channels in European port. The proposal of more reasonable Japanese standard will be expected by applying the study result of naval architecture and navigation and by the cooperation of ship operators to use fairway, naval architects to built ships and civil engineers to dredge fairway. The concept of a fairway in 'Design standard fur fairway in next generation' is defined as passage for approach channel) and traffic lane designated by light buoys as navigable water for safe navigation. In 'Design standard for fairway in next generation' depth, width and alignment are picked up among many design elements of a fairway. Design method for those elements is shown based on design ships and navigational environments. This standard shows the method of design for each dimension depending on characteristic on design ship and weather and sea condition. On the other hand, in case of existing fairway, it is possible to decide the size of ship and navigation criteria by opposite analysis.

Architect Bernard Tschumi had explored a new architectural conception through his own notional devices such as space, event and movement during 1970s. But, among these notions, the concept of movement was ambiguous and difficult to adopt it for architectural design strategy. Because the movements in everyday's behaviour or in dancing art are significantly different from architectural thought. However he had succeeded in coining the creative notion of movement as almost real body's and of living flesh. He invented an acute methodology and bold interpretation for his early experimental works. So, this paper tried to understand and analyse his concept of movement focused on his early works. The results of this paper's discussion are as follows; First, Tschumi's movement concept Is dynamic one operated by desire and can violate space in physical level as well as metaphysical level. Next, the movement performs the role of generator which deforms space or even generate it. Third, his movement can be readable only when you go down and bring it in practice. Also it Is unblocked potentiality, undetermined sequential material and unfinished practice. Fourth, when Tschumi's movement could be thought as walking, this walking movement makes up a story through rhetorical speech acts that are presented by turns and detours.

The proposed clock generator lowers the operating frequency in a system core though it keeps data bandwidth high because it has a multiphase clocking architecture. Moreover. it has a dual loop which is comprised of an inner analog phase generation loop and outer digital phase control loop. It has both advantages of DLL's wide operating range and DLL's low jitter The proposed design has been demonstrated in terms of the concept and Hspice simulation. All circuits were designed using a 0.25${\mu}{\textrm}{m}$ CMOS process and simulated with 2.5 V power supply.
