Day care center for the elderly is an alternative for community care for frail elderly who need social participation and physical cares and services outside the family. The purpose of this study was to identify the present situation of day care center for the elderly and to suggest desirable interior space plans for elderly day care center. Data were collected by two ways; a mail survey and case studies of existing day care centers. Five cases of day care centers were analyzed to find out Physical and space problems, available programs and services. Also, the staffs in 96 day care centers for the elderly in nationwide were selected for a mail survey and 68.8 percentage of all was collected and analyzed. From the result of case studies, narrow space and lack of accessibility features for wheelchair or other prosthetic devices were the major problems. From the result of a mail survey analysis, the elderly users were over 73 years old, and high proportion had suffered from dementia and apoplexy Also, staffing ration was 1:7 In other words, one staff was caring of 7 old people, and supporting staff was insufficient. Therefore, supportive, therapeutic environment Was more important issue to improve quality of care. Separate program room and outdoor space, lounging space, treatment room by gardening, separate counselling room, bedroom, a simple kitchen unit, staff office, separate physical treatment room, resting room for staff was indicated more necessarily. When priority of planning interior space was safety followed by accessability and convenience, it was also reported that sire of each room was generally narrow. The most serious problem in interior space was the lack and narrowness of space, and accessible features for mobility. Based on the literature review and the findings of this study, two types of floor plans for elderly day care center were suggested;‘a mixed type for the elderly with and without dementia’and‘a separate type for the elderly with dementia.’The main goals for designing interior space for two types of elderly day care center were to provide safe environment, encouraging environment for remaining abilities of users, sanitary environment, therapeutic environment, familiar environment, and socially-encouraging environment. The recommendations for further studies were suggested.

The atmospheric flow in the 3-Cell model of global atmosphere circulation is described by the Lagrange's equation of the non-inertial frame where pressure force, frictional force and fictitious force are mixed in complex form. The Coriolis force is an important factor which requires calculation of fictitious force effects on atmospheric flow viewed from the rotating Earth. We make new Mathematica platform to solve Lagrange's equation by numerical analysis in order to analyze dynamics of atmospheric general circulation in the non-inertial frame. It can simulate atmospheric circulation process anywhere on the earth. It is expected that this pedagogical platform can be utilized to help students studying the atmospheric flow understand the mechanisms of atmospheric global circulation.

20 children who visited department of pedodontics, S.N.U. Hospital were examined and their study models were obtained. The data obtained from three groups of operator, three method, twice measurement, was analysed. The results of the study were as follow: 1. The Brass-wire method appears to be the least desirable of those examined for space predictions in all three groups of operators. 2. It appears that there is little clinical significance between Moyer's and Segmented-arch method in all three groups of operators. 3. The Moyers' method appears to be more easily conceptualized by inexperienced operators than the other two methods.

An interface crack of a piezoelectric medium bonded between an elastic layer and a half-space is analyzed using the theory of linear piezoelectricity. Both out-of-plane mechanical and in-plane electrical loads are applied to the piezoelectric laminate. By the use of courier transforms, the mixed boundary value problem is reduced to a singular integral equation which is solved numerically to determine the stress intensity factors. Numerical analyses for various material combinations are performed and the results are discussed.

In this paper, we consider the functional equation f(x + 2y) - 3f(x + y) + 3f(x) - f(x - y) - 3f(y) + 3f(-y) = 0 and prove the generalized Hyers-Ulam stability for it when the target space is a fuzzy Banach space. The usual method to obtain the stability for mixed type functional equation is to split the cases according to whether the involving mappings are odd or even. In this paper, we show that the stability of a quadratic-cubic mapping can be obtained without distinguishing the two cases.

The purpose of this study was to test the effectiveness of the light-shelf system combined with IT to save lighting energy in resident space. According to the multiple variables that affected intensity of illumination, various experiments were designed and conducted. The main findings of this study were following: (1)the optimal level of light-shelf system was formulated which met the appropriate range of intensity of illumination in living-room; (2)although the mixed light-shelf system indicated a high performance, it could often provide discomforts to residents according to the degree of exposure; (3)artificial lights using light-shelf system combined with IT showed a higher effectiveness than those using fixed light-shelf system displayed. This study provided initial information of light-shelf system formative processes that could contribute to the lighting energy diminution. Future studies should focus more on multiple approaches regarding different types of resident space planning.

The objective of this study is to apply the modular furniture system, which has been developed actively in western Europe and America since 1970's, to Korean contemporary furniture having converted into western style gradually. The factors requiring the modular furniture system in today's residential environment are as follows; 1. Population increase and urbanization 2. Development of industrial technology 3. Improvement of living condition and change of life style. As these factors increase the problem of diminishing space, multiple functional modular furniture concept has become a solution. Reviewing the current scene of the western modular furniture system, it is classified into modular seating system, mopular wall system, modular commode system and modular storage system. Korean wardrobe, which is am mixed style of traditional and contemporary furniture, should change to a closet eventually because of the grand size and unpractical use of space. Since most Korean family, however, have wardrobes already, it will be necessary to have a turning period to systemized the closet space in Korean residential interior. For the turning period, application of the modular wall system would be one answer to substitute the wardrobe.

The author observed the changes of dental arch dimensions and compared spae-maintainer group with non-space-maintainer group after primary tooth extraction. The results were as follows 1) The rate of growth of dental arch of expeirmental group in intercanine width and in inter-1st molar width was more rapid than that of the control group. 2) Arch length is almost no dimensions but it was slightly decreased in lower arch. 3) Dental arch growth and tooth eruption were stimulated by space-maintainer appliance, so it is the best way to replace a new appliance at least once a year. 4) It is thought that satisfactory conclusions in this observation must be researched successively until the mixed dentition completes.

A Fabry-Perot interferometer has a very high (~1,000,000) resolution, so recently this has been widely used for many fields of space science. To understand the working principle of this a mathematical modeling is needed, and to analyze the interferogram it is essential to know the precise instrument function. The spectrum from the interferometer is mixed with a true signal from the light source and the instrument function through convolution. The true signal has the information about the quantum state of mo lecules, temperature and bulk motion of the gas. Therefore if we model the signal and convolve this with the theoretical instrument function we can predict the spectrum for the real case.
