Recently, housing consumers are demanding new types of residential housing and environmentally friendly housing. I think that the related issues and problems can be solved by introducing various types of independent housing. Garden is an important space for single family housing, providing calmness and restfulness etc. Furthermore, it provides a green space for our city. According to the result of this paper, I would like to suggest some important conclusions. 1) Residents in single family housing want sufficiently large garden space and they need good design of planting. 2) They are interested in gardening. They also want to have various ideas and information for gardening and need useful skills to prevent their garden from insects and diseases from the garden maintenance companies. 3) Generally, they want to design their garden for the usage of their relaxation and ornamental enjoyment.

This study aims at examinating the change of architectural technique in the residential district of Seoktanri(石灘里), and then extracting the restorable types from it. The constructive technique was advanced in the composition of walls and the use of footing. The arrangement of columns was developed to standing them in a row and three rows in the center of interior space. In the light of excavated relics and the position of furnace, the interior space is seperated into cooking-heating, working and storing space. By the difference of height and the slope, the floor is divided into two parts which are low and high. According to the arrangement of column-holes, the types of roofs to be restored are as follows; the gable roof without column-hole, the hipped roof with center-column-holes(中央柱孔) in a row and the gable roof with center-column-holes in three rows.

We present medium resolution spectra in the near-infrared (IR) band 1.4-1.8 microns at a resolving power of R = 5000-10000 of template stars in G, K, and M types with luminosity classes of III observed by the echelle spectrometer, IRCS, at the SUBARU 8.2 m telescope. Identification of lines in the template star spectra has been completed base on the reference of Arcturus spectrum. We measured equivalent width (EW) of the lines, and analyze the trends of EW through the stellar spectral types.

This paper presents bounding space(BS) management for real-time visual simulation when using GK-DEVS models. Since GK-DEVS, extended from DEVS formalism, has information of 3D geometry and 3D hierarchical structure, we employs three types of bounding spaces: BS of its own shape, BS of its children GK-DEVS, and total BS. In addition to next-event scheduling functionality of previous GK-Simulator, its abstract simulation algorithms is extended to manage the three types of BSs so that BSs can be utilized in the rendering process of a renderer, so called GK-Renderer, We have implemented the method and evaluated it with an automated manufacturing system. In the case study, the proposed BSs management method showed about 2 times improvement in terms of rendering process speed.

In this paper, the concepts of compatible mappings of types (A) and (P) are introduced in an induced metric space, two common xed point theorems for two pairs of compatible mappings of types (A) and (P) in an induced complete metric space are established. As their applications, the existence and uniqueness results of common solution for a system of functional equations arising in dynamic programming are discussed.

Different types of deterministic solution methods were used to solve neutron transport equations corresponding to half-space and slab albedo problems. In these types of solution methods, in addition to the error of the numerical solutions, the obtained results contain truncation and discretization errors. In the present work, a non-analog Monte Carlo method is provided to simulate the half-space and slab albedo problems with Inönü and Anlı-Güngör strongly anisotropic scattering functions. For each scattering function, the sampling method of the direction of the scattered neutrons is presented. The effects of different beams with different angular dependencies and the effects of different scattering parameters on the reflection probability are investigated using the developed Monte Carlo method. The validity of the Monte Carlo method is also confirmed through the comparison with the published data.

The general properties of the NCBs, divided into A and F types according to their spectral types, have been presented. The evolutionary status of the F type near-contact binaries are closer to that of the contact systems, i.e., W UMa type binaries, if it is assumed that the evolution of the NCBs is governed by the thermal relaxation oscillation theory. The mass-radius relation, mass-luminosity relation and H-R diagram of the NCBs provide that the A type NCBs suffer from more active mass transfer than F types. The components of the NCBs ar still in main-sequence like W UMa type stars and their two components lines parallel to the ZAMS.

The vibration characteristics of rotating machinery are directly related withits condition such as rotor types, thereby it should be acquired the information fromthe vibration signal so that operating conditions may be rationally decided.Accordingly, the study is to focus on developing the analysis for identifying theoperational feature of rotor systems. For this purpose the complex frequencyanalysis for identification, which utilizes the directionaI spectrum for effectiveidentification of rotor systems, is introduced. From this proposed method, theanalysis of dynamic model of the rotors is performed including the stabilitybehavior of the general rotor by Ftoquet theory. Through this process theexcitation methodology to identify the types of rotors is investigated and theeffective way to identification is also suggested.

This study has a subject for the detached houses and mass housing ( alias dictus, Apartment) on the Dae Gu urban area, and has a process of surveying and analyzing the actual using states of dweller in the residential space and has an object of finding the behavioral pattern of the spatial using corresponded to the living activities. As its result, a cultural searching for urban housing is disciplined with the positive study for surveying the living contents emerged form the residential spaces. Limited into sleeping, eating, hosting, familiarity and family ritual, where and how the living activities is appeared according as the housing types and floor types, and what different and common features of its spatial using is possessed, is focused on this study. As Conclusion, it is found that each living activities are differed in the spatial using behavior according to the housing and floor types, but genetically are inherited by the traditional custom. Thus two behavial directions of dweller in public residential architecture have to be reconsidered in the urban housing culture.

The widespread introduction of unmanned aircrafts has led to the understanding of the need to organize a common information space for manned and unmanned aircrafts, which is reflected in the Russian Unmanned aircraft system Traffic Management (RUTM) project. The present article deals with the issues of spatial information database (DB) organization, which is the core of RUTM and provides storage of various data types (spatial, aeronautical, topographical, meteorological, vector, etc.) required for flight safety management. Based on the analysis of functional capabilities and types of work which it needs to ensure, the architecture of spatial information DB, including the base of source information, base of display settings, base of vector objects, base of tile packages and also a number of special software packages was proposed. The issues of organization of these DB, types and formats of data and ways of their display are considered in detail. Based on the analysis it was concluded that the optimal construction of the spatial DB for RUTM system requires a combination of different model variants and ways of organizing data structures.
