Since its foundation of Won-Buddhism in 1916 there established around 500 Temple-Halls in both domestic and overseas areas, and it is a native religion that currently on its development of edification activities. As for Won-Buddhism which being under rapid development likely as such going, together with its expansion of the religious influence, there required more broader spaced grand sanctum at where the large-scaled religious events are able to perform. According to this, Balcony-styled plane form is on increasing trend from the internal plane form of Won Buddhism Sanctum. On such viewpoint, this study hereby intends to grasp the character of room acoustics through on-the-spot survey about the objects of 3 Won Buddhism Sanctums which equipped with mutually different characters of the balconies already built, and willing to furnish the fundamental material which enables to improve acoustic capability when design Won Buddhism Sanctum equipped with balcony in the future.

Automation tools for program analysis are needed in order to program understand and maintain, extract the characteristics of object-oriented program such as class name, member function and data member. In this paper, we carried out design and implementation of the automation tool for effective maintenance of object-oriented software. Being based on Reverse Engineering, this approach extracts class relationship information from C++ source code and generates object-oriented model of class diagram using UML as the standard object-oriented methodology. Therefore, this paper provides developers visualized including class information, definitions of classes, inheritance relationships, set relationships, and simple reference relationships. Finally in this paper, we propose a method that construct class relationship information to table in analysis state and make form of table construction to link form so tat developers can perform understanding and maintaining program efficiently. And this method enable to restructure and reuse in object-oriented model.

As the form factor of the disk drive is decreased, many mechanical issues that are negligible in larger form factors, should be considered for the design of the miniature drives. This paper deals with basic research on vibration characteristics and design considerations of small disks and actuators. The natural frequencies of micro-sized disks with polycabonate and glass substrates are experimentally measured, being compared to FEM results. In order to investigate the effects of rotating speeds, airflow and disk size on power consumption. we measure power imposed to spindle motor when different optical disks are spins in vacuum chamber. Finally, The vibration characteristics of the micro actuator used in a IBM Microdrive are experimentally studied for the application to the basic design of micro optical disks.

The multimedia techniques have changed form of media because of digital media technique. It is notable change that this is possible with the interaction of media. The human being present the interaction of the form using by the difference of expression. The treatise proposes the method, which increases the interaction of the On-Line game system. It is analyze that an online game UI and expand by interface. It will be to the offer an opportunity which the parity game for various age gammer.

In the middle of that a information form is being formlessly changed to diverse deirections, a design and a space as physical consequence show not only a allegory but mutually relational charicteristic meaning a nonboundary and nonlinear form by development of modem digital culture. Following development of the modern digital culture, a design and space which are physical results, show a point of correlative specificity, allegory, nonlinear and nonboundary, Not only a design and culture but also various circles handle a hypertext as a representative pivot in this change. this has same contexts as rhizome possessing a asignifiante and nomadic characteristic said by Felix Guattari and Gilles Deleuze. An ideal of rhizome space shows historical decisions, unexpected accidents, a concepts, an individual. a group, social compositions above an contrifugal exterior force, This study examines into surroundings designed by a hypertext and rhizome through a case accordingly and infers an ultramodern characteristic in conventional precognition with synthesizing a peculiarity of the digital generation space.

The occurrence and distribution of Dictyostelid cellular slime molds on Mt. Mukak soils with two different vegetation types were investigated. Two plating methods were used for the isolation of dictyostelids following Dr. Hagiwara's method. Dictyostelium and Polysphondylium were isolated in these soils. D. purpureum (subtropical form ) and D. giganteum were observed in both Quercus variabilis and Pinus thunbergii communities soils. D. delicatum, B. sp-1 (D. brefeldianum complex). D. sp-2 (D. brefeldianum complex), D. minutum and P. pallidum complex occurred only in Q. variabilis soil. D. macrocephalum, D. purpureum (temperate form ), D. robustum, D. polycephalum, P. violaceum, and P. pallidium occurred only in P. thunbergii soil. P. pallidium complex is being identified.

Dome structure to form a space-efficient, applied a lot of beautiful buildings with structural systems, as well as a large space structure in the form of new residential lots have been applied. And domestic demand for housing in the dome with increasing dome house using various materials, are becoming commonplace. But now the Dome House is mainly used in construction steel, wood, stone, FRP construction and building materials per unit area and the high cost, long construction time, energy efficiency, has some disadvantages such as degradation. And structural strength of the structure is weak, the natural ingredients used come from natural damage is so big. In addition, demolition of buildings in trouble when handling the environmental problems has emerged. Recently expanded polystyrene to improve these problems by using the various approaches and research is being attempted and there.

The most popular convergent services are being made mostly out of IT related services and devices. To help understand the underlying principles making convergent services the paper suggests a logical view of converging process. A service is assumed to consist of unit services that can be used in algorithmic operations to form a new convergent service. Convergence operations for a couple of unit services are typed according to whether the unit services are modified. Internal convergence leads to a new service from a combination of sub units of the two unit services. External convergences do not alter original unit services but simply combine them to form a new service. The paper also suggests several measurements to evaluate the convergent services with respect to the existing services used to create the new convergent service.

The purpose of this study is to provide the new method for selection of a close to optimal scalar control of linear time-periodic system. The case of scalar control is considered, the gain matrix being assumed to be at worst periodic with the system period T. The form of gain matrix may have various kinds but must have same period, for example, one of each element being represented by Fourier series. As the optimal gain matrix I consider the matrix ensuring the minimum value of the larger real part of the Poincare exponents of the system. Finally we present a pole placement algorithm to make the given system be stable. It is possible to determine the stability of the given periodic system without get the analytic solution. The application of the method does not require the construction of the Floquet solution. At present state of determination of the gain matrix for this case will be done only by systematic numerical search procedures.

The purpose of this project is the presentation of new method for selection of a scalar control of linear time-periodic system. The approach has been proposed by Radziszewski and Zaleski [4] and utilizes the quadratic form of Lyapunov function. The system under consideration is assigned either in closed-loop state or in modal variables as in Calico, Wiesel [1]. The case of scalar control is considered, the gain matrix being assumed to be at worst periodic with the system period T, each element being represented by a Fourier series. As the optimal gain matrix we consider the matrix ensuring the minimum value of the larger real part of the two Poincare exponents of the system. The method, based on two-step optimization procedure, allows to find the approximate optimal gain matrix. At present state of art determination of the gain matrix for this case has been done by systematic numerical search procedure, at each step of which the Floquet solution must be found.
