In this study, problems with table serving of Korean Jeollanamdo food were investigated, and methods for improvement were suggested. The manner of food serving and arrangement on tables, as well as the serving space in each case, were investigated in representative restaurants serving Jeollanamdo food. The results showed that most of the Jeollanamdo Korean food have a prototype of a flat serving sprea, wherein the main dish and side dishes are not clearly identified, the demarcation between shared space and personal space is insufficiently made for each serving on the table, and the table is full of side dishes, that are narrow, visually disordered and unhygienic, both in terms of the table setting and arrangement inside bowls. To provide sufficient eating space, elevate awareness of hygienic and clean serving, and identifying the main dish in the table setting, a serving method that is a compromise between the flat spread-out and time-series development was suggested, and an arrangement on the table was defined for the main dish and side dishes. The utilization of table space was also increased by reducing the number of dishes on the table at a given moment. In addition, the dish or bowl and arrangement inside the container were changed in order to distinguish the main dish and side dishes. It is suggested that some of tableware be linked with the special products of the locality so as to make a brand for them, and that a personal mat be used to arrange the tableware for each one, since there are many fermented food items (salted fish, kimchi, fermented paste and sauce, etc.) and boiled food items (stew, steamed dish, boiled dish in sauce, etc) that look dark and unfocused. In addition, it is suggested that the width and breadth of the dishes or bowls be set in an orderly manner. Considering the tables currently available at restaurants, personal space on a table and comfortable distance between eaters are suggested to be $400 mm{\times}250 mm$ and 300 mm, respectively.

In this paper, we study some equivalence relations between continuous frames in a Hilbert space ${\mathcal{H}}$. In particular, we seek two necessary and sufficient conditions under which two continuous frames are near. Moreover, we investigate a distance between continuous frames in order to acquire the closest and nearest tight continuous frame to a given continuous frame. Finally, we implement these results for shearlet and wavelet frames in two examples.

In this paper, we use the convexity of distance function between geodesics in a singular Hadamard space to generalize Hadamard-Cartan theorem for 2-dimensional metric spaces. We also determine a neighborhood of a closed geodesic where no other closed geodesic exists in a complete space of nonpositive curvature.

A method to find the line of sight ray in space which corresponds to a point in an image plane is presented. The line of sight ray is defined by two points which are the intersections between the two calibration planes and the sight ray. The intersection point is found by the oblique coordinate mapping between the image plane and the calibration plane in the space. The proposed oblique coordinate mapping method has advantages over the transformation matrix method in the required memory space and computation time.

In space syntax, the mathmatical process to get a integration could be restrictive in understanding spatial configuration since it is based on only one behavior model. In this study, As another approach to spatial configuration analysis based on behavioral model, there is the simulation tracking analysis model that simulates the movements of human in the space and analyze them. In this study, the relationship between integration and behavioral model will be defined and the similarities and the differences between space syntax and the simulation tracking analysis model will be demonstrated. Furthermore, these two analysis models will be understood as a variety of tools that can analyze an object in multiple viewpoints.

Ron Arad, the master of contemporary design in the U.K., is one of representative leaders of this age who has left distinguished achievements in the history of contemporary design through innovative design. Analyzing and understanding the Deconstructive design concept and the deconstructive characteristics of interior space of Ron Arad will contribute to finding directions for today's design and laying the ground for explaining the development pattern of design in the 21st century. After analyzing the deconstructive characteristics of each selected space, One Off and Ron Arad Associates have shown a deconstructive design trend of a creative formula by using methods that shed conventional processes and material while a space composition and form of new concept was attempted in the resting space of the New Tel Aviv Opera House, offering not only the establishment of a new circulation system, but also diverse experiences of space to visitors. Likewise, a temporal experience and communication between the user and the space was attempted in Belgo Noord and Belgo Central by partially applying a narrative space composition that sheds existing design concepts. At the Millennium House, they have produced an interior space for future house developed by breaking off from existing typical design development work and material through computer operation, and made various forms of space and atmosphere possible by attempting variable elements and the use of ultramodern material. Y's fashion shop has granted variability to the form and volume of space according to time by presenting display elements that have shed existing form and function. Hotel Puerta America as well, with a curved structure that has broken off with existing forms and maximized space variability through structures that have utilized ultramodern materials and instruments. Through this study, it has been verified that Ron Arad has been unraveling connections between interior space and its user, its requirements, and the original unique principles of space by applying deconstructive design concepts, and that through the mediation of these spaces, he is attempting indirect communication with the user. Eventually, he is taking part in the harmony and development of all elements of space connected with human beings by applying deconstructive design concepts.

According to the relative stiffness between the half-space and plate or loading condition, some parts of the plate can be separated from the half-space. The finite element procedure to determine the contact area by considering the distribution of contact pressure between plate and the elastic half-space is developed. The vertical surface displacements of the elastic half-space can be obtained through the integrations of the Boussinesq's solution for a point load. The rectangular plate on the elastic half-space is modeled by the 8-node rectangular and 6-node triangular elements and the Mindlin plate theory is used in oder to consider the transverse shear effect. In this study, the contact area may be determined approximately by the analysis with rectangular elements. From this results, the mesh pattern is modified by using triangular and rectangular elements. The contact area can be determined by the new mesh pattern with a relatively sufficient accuracy.

This study aims to embody material and non-material factors forming space and to explain our experience in space. Space is formed by material factors and their disposition. One space becomes a new space by such factors 'arrangement. Nevertheless, one space is never swayed by material factors and their disposition. Space is a reflection of social relations and historical process, and is also affected by its users. Space can not neutrally exist, for it compels its users to keep a specific life style. Space users have experience in space by practice. Practice enables its users to experience various relationships space makes, and as well it allows them to have creative experience in space by twisting them and inducing a new relationship.
