The mechanical behavior of rectangular foundation plates with perimetric beams and internal stiffening beams of the plate is herein analyzed, taking the foundation design into account. A series of dimensionless parameters related to the geometry of the studied elements were defined. In order to generalize the problem statement, an initial settlements was considered. A numeric procedure was developed for the resolution by means of the Finite Differences Method that takes into account the stiffness of the plate, the perimetric and internal plate beams and the soil reaction module. Iterative algorithms were employed which, for each of the analyzed cases, made it possible to find displacements and reaction percentages taken by the plate and those that discharge directly into the perimetric beams, practically without affecting the plate. To enhance its mechanical behavior the internal stiffening beams were prestressed and the results obtained with and without prestressing were compared. This analysis was made considering the load conditions and the soil reaction module constant.

In current society, products and services are positioned to match customers' lifestyles and emotions. One example of such can be collaboration strategies. Various types of collaboration can be found and should be applied to academic research in terms of fashion designing as well as in marketing. As a result, this research focuses on defining collaboration and identifying its different forms. Case studies are provided for each form of collaboration. A set of emotional factors required for collaboration and a domestic fashion brand is selected in order to carry out analysis and design production. As a result of this study, the following conclusions were reached. First, collaboration can be defined as two or more companies, brands or even individuals working together for an agreed period of time by sharing core competencies and advantages in order to pursuit profit and value creation. Second, collaboration types can be specified into two categories which are collaboration between companies within the fashion industry and collaborations with companies outside the fashion industry. In addition, companies may collaborate with the purpose of enhancing value, broadening its areas of business and to execute an event. Third, according to the case studies examined, effects of collaboration can be upgrade of brand images, variety of promotional benefits and increase in sales. Fourth, the selections of collaboration targets were made. MOGG and Sex&the City were chosen in order to apply collaboration strategies in line with promoting the domestic womens' wear market. Fifth, by considering and applying all the findings from the research, the limited edition line was produced under the design concept of 'Sex and the City with MOGG'.

Theses days, there are 3 prerequisites for dam building in Korea: First one is how to build the dam safe and stable from the technical points of view. Second one is how to design and construct the dam environmentally sound with the minimum change of the surrounding area of the dam site. Third one is how to activate the local economy of the surrounding area of the dam site in order to make the dam construction sustainable from the social and economical points of view. As far as technical aspects far dam building, there are hardly any problems in dam design and construction in our country. However, there are a little difficulty according to the location of the dam site. In order to fulfill the second option it is believed that a lot of effort should be made to accomplish the second task not only because that fairly large area shall be inundated with water after impounding but also because that ecological environments shall be changed due to change of water environment. Therefore, thoughtful investigation and assessment of the environmental features of the local regions have to be preceded before starting of the dam building. In order to overcome these difficulties Hantan river dam has been declared as an Eco-dam with 3 strategies and 9 activities plan at the design stage after sufficient consideration of the local identities of these region and coupled national plans for surrounding areas. Finally, Eco-tourism with the several coupled network-wise touristic courses, namely PERTH model, has been proposed after thorough analysis of the local identities by the Jahari window to make local economy being activated. Detailed descriptions for 3 strategies and 9 activities plan for declaration of Eco-dam and proposal of Eco-tourism with the network-wise touristic courses will be mentioned in the main content.

We have developed a planar-type single layer second-order $high-T_{c}$ SQUID gradiometer, which can detect the $d^2$$B_{z/}$dxdy of the second-order field gradient. This SQUID gradiometer consists of four-way 'clover-leaf' pick-up loops and is coupled directly to a 4-junction dc SQUID in such a way that the coupling polarity of the two diagonal loops is opposite to that of the other two loops. The pickup loops are intrinsically balanced for both uniform field and the 1 st-order field gradient. The $YBa_2$$Cu_3$$O_{7}$ thin film was made by pulsed laser deposition method on $SrTiO_3$ single crystal substrate and patterned by photolithography with Ar ion milling technique. Response of this gradiometer was tested for both uniform field and the 2nd-order field gradient. Details of the design, fabrication, and results will be discussed.

A transfer paper, is needed in the third firing, is usually utilized for industrial ceramics in order to produce tablewares or promoting products. Products may have the same form, however; the price might be different by what kinds of design have transferred. We need to fully understand these methods in order to create high value and quality. Remodeling, the so-called second architecture, results from social Needs for renovation of structures and changing functions. Tile satisfying the need for a custom-made design which fits the features of a space. Most importantly, the remodeler must make an individual design ordered for the customer with an emphasis on economy and time efficiency. Tiles currently in the market are mass-produced using an automated system with a high-priced mold. It is difficult to find tiles of distinct design that are made in a small quantity. We need to develop a method for making various kinds of tile designs that would be marketed for the remodeling industry. In this study, after designing a certain wall with the tiffs in the space, 1 will talk about developing a method to make transfer paper to produce individual tiles for the space. 1 hope that the functional and aesthetic effect on remodeling will gain in popularity, and that we will foster a new demand for tiles in harmony with the other materials mentioned in this study.

The present study aims to design electrically and structurally effective antenna structures in order that the structural surface itself could become the antenna. The basic design concept is composite sandwich structure in which microstrip antenna is embedded and this is termed composite smart structure (CSS). The most important outstanding problem is that composite materials of structural function cannot be used without reducing antenna efficiency. Unfortunately, such materials have high electrical loss. This is a significant design problem that needs to be solved in practical applications. Therefore, the effect of composites facesheet on antenna performances is studied in the first stage. Changes in the gain of microstrip antenna due to composites facesheet have been determined. 'Open condition' is defined when gain is maximized and is a significant new concept in the design of high-gain antennas considering bandwidth in practical application. The open condition can be made with any thickness of outer facesheet by controlling its position. In the design of CSS, glass/epoxy composites and Nomex honeycomb were used with exploiting open condition. Experiments, confirm that the gain is improved (over 11 dBi) and the bandwidth is also as wide as specified in our requirements (over 10% at 12.2 GHz). With the open condition, wideband antenna can be integrated with mechanical structures without reducing any electrical performances, as confirmed experimentally here.
