The purpose of this research is to obtain an empirically-based understanding of the attitudes of those children and mothers living in three different housing types : detached houses. row houses / villa and apartments. The subjects are 547 elementary school children in the fourth, fifth and sixth grades and their mothers in four different residential areas, Seoul. Followings are the result of this research. 1) Mothers put the first priority on the convenience of the dwelling space from the educational point of view, and they make complaints about their present dwelling space, in particular, children's play and storage space and the size of children's room. 2) They care a lot about the size of housing and, if the size of the housing is held constant, the mothers living in the apartments have more complain about. 3) The difference in the way children and mothers regard their dwelling space is great. The mothers would like to draw a clear line between rest space and play space. They would like to see their children play in their rooms, but children want to make use of the whole space of their housing for play. 4) Mothers think that the children's rooms should be used primarily for study while children think that their rooms have multiple uses such as studying, resting, and playing.

The 76 cm telescope in Kyung Hee Astronomical Observatory is participating in the small telescope network of the SomangNet project, which started in 2020. Since the installation of the telescope in 1992, the system configuration has been changed several times. The optical system of this telescope has a Ritchey-Chrétien configuration with 76 cm in diameter and the focal ratio is f/7. The mount is a single fork equatorial type and its control system is operated by TheSkyX software. We use a science camera with a 4k × 4k CCD and standard Johnson-Cousins UBVRI filters, which cover a field of view of 23.7 × 23.7 arcmin. We are also developing the Kyung Hee Automatic Observing Software for the 76 cm telescope (KAOS76) for efficient operations. In this work, we present the standard star calibration results, the current status of the system, and the expected science capabilities.

The purpose of this study is to use as the basic data for design method in commercial space. So, we analyzed whether any emotion was induced by finishing materials in the commercial space. And we was to suggest expression methods of finish materials to induce in the emotional space. The results of this study are as follows : First, we could know that the emotional design is needed to enhance satisfaction of consumers. The role of finishing material is very important in emotional expression in the commercial space. Second, we extracted the adjectives vocabulary(14 pairs) to evaluate the space emotion. we could educe the four kinds of space emotion by Factor Analysis. In addition, we could arrange the emotional words to represent each space type(Decoration : 5 pairs, Expand : 4 pairs, Limitation : 3 pairs, Hierarchy : 2 pairs). Third, to use finishing materials and wall is very effective to induce the emotion in the emotional space. To use the color is good among the elements of finishing materials. Fourth, We could find that the center of the types of emotional space was induced with the boundary and the decoration. If we use contrasting colors and accent colors in the commercial space, we can induce the center and the boundary together. And if we use colorful or unusual patterns, we can induce the center and the decoration together. Fifth, To induce the expand, we should finish with one color in space. And To induce the center, we should finish with one type of the color or pattern and then we should partially use the contrast color and special pattern. the case of boundary, it is good method to part emphasize by color, texture and materials. And we can induce the decoration with materials and patterns.

The purpose of this study was to suggest the idea for IAQ improvement of university dormitory through space analysis and residents' evaluation. The data was collected from 105 Konkuk university dormitory residents by a questionnaire survey. As a result, the idea for IAQ improvement of university dormitory can be suggested. First, it was found that it was necessary to improve size of windows and to exchange bathroom exhaust system for ventilation. Secondly, it is important for resident to ventilate and clean their room. Thirdly, the educational program for dormitory residents about maintenance of IAQ was esssentially needed. Also, it is necessary to manage air conditioning equipment maintenance and bathroom hygiene.

In this paper, a method to apply the simulated annealing method to three dimensional layout design problem which has multiple constraint conditions and evaluation criteria, was suggested. A program to support three dimensional layout design was developed according to the suggested method. This program was applied to the layout design of the wireless unmaned ocean space submergible boat. The layout result was improved 19.0% for the result of layout design expert. By this, it was verified that the suggested method has validity in supporting three dimensional layout design problem.

The purpose of this study is to evaluate the coastal nightscape of Yeong-Do in Busan in order to make an effective management plan of coastal nightscape. Firstly the coastal area of Yeong-Do has been divided into 8 nightscape sections. And then the nightscape images of each section have been evaluated by volunteer subjects through SD(semantic differential) analysis method.

This study is compare to model-based analysis and experimental data of the response characteristic of interior impulse noise. Interior impulse noise and the pressure response characteristics of the building structure on its analysis are presented the impulse pressure acting on the rear wall 90 N-sec. The force acting on the wall $CFD^{{+}{+}}$ which are compared measurement and simulation analysis. Results of simulation and measurement data were shown. In this study, a high dimension of the degree of virtual space in the numerical space of the lesser degree in order to calculate folding method was applied. The results of this study contribute safety evaluation and model development for the interior impulse noise that affects the basic data for the interior impulse noise model validate for the physical quantity prediction.

Structural health monitoring has been conducted by non-destructive evaluation method when a turbine rotor system of an aircraft engine has cracks. Local stiffness of a turbine rotor system is degraded and critical speed is changed due to the presence of cracks in rotor. Critical speed which is affected by location and depth of crack, is obtained using compliance matrix of cracked rotor. The database of the obtained critical speed is used to evaluate structural health monitoring of a rotor system of a gas turbine engine.

A complete analysis of the color-viewing-angle properties of different displays is presented herein using color-viewing-angle measurements made with a Fourier-optics system. The color gamut in the CIE u'v' chromatic plane was computed for all the viewing angles. The introduction of the lightness using the $L^*a^*b^*$ color space allowed a more precise analysis of the emissive properties of each display. The displays can be directly compared using a common reference. The viewing-angle dependence can be analyzed in full detail using the on-axis values as reference. The gravity center behavior and area of the color hull were computed for a more precise evaluation and comparison.
