Concerns about paid-facilities for the elderly with dementia from middle and upper class families have been discussed lately in Korea. Small-scale, home-like group homes for the elderly with dementia were developed in Sweden in the 1980, but they have not been effectively introduced in Korea where they remain a comparatively new concept. The group home, however, would provide a good alternative to Koreans who feel guilty when they have to leave their frail parents in large-scale facilities or hospitals instead of caring for them at home. The aim of this paper is, first, to define the care of the demented elderly who come from upper and middle class families in Korea and, secondly, to discuss the need for group homes to help care for them. A survey was done by questionnaire and was answered by 577 respondents who belonged to middle and upper class families living in Korea in December 2000. Methods of analysis were frequency, mean, and Chi-square. The results of this study were as follows: 1) the traditional notion that the eldest son should be burdened with the primary responsibility for a demented parent has weakened remarkably; 2) a small-scale long-term care facility was considered the most desirable living environment for the demented elderly; 3) the facilities families needed for professional hospitals for victims of dementia, senior citizen centers, large and small-scale long-term care facilities, day-care centers, and short-stay and service housing. The study also revealed that there was low awareness of the group home. The most preferred type of structure for group homes was a single-family detached house, and the most preferred management system was small-scale that could create home-like atmosphere. Additionally the respondents wanted group homes to consist of 6-8 residents with 2-4 persons per room. The results of this study strongly suggest that policy makers should encourage the development of smallscale group homes as an alternative form of housing for the elderly with dementia.

In the present study the meaning of table in the Joseon dynasty period and also in the present age was researched, and its changing according to the times was searched as well. The results are as follows. First, the meaning of table in the Joseon dynasty period and in the present age has one thing, "laying something on table" in common from the functional aspect. Whereas the table in the Joseon dynasty period had the function of laying and keeping articles or decorations, that of the present age contributes to reading and doing office work of human beings and this exceeds the simple function to keep articles, because it touches parts of the human body, so it combines function of comfort accordingly, not only the function of storage. Second, it was differently presented from the aspect of shape. The table of the Joseon dynasty period strongly showed the shelf-like shape due to the set-up in layers, while the table of the modern times has the rectangle-like form in one layer. It has been transformed according to the functional changes. Third, it is different also from the constructive aspect. The table of the Joseon dynasty period had the construction with one panel on 4 legs in layer upon layer, but the table today has one upper panel on legs supporting it. Namely, the term "table" has been constantly used from the Josen dynasty period until today, but it has a totally different meaning according to the times on the basis of the changes in function and shape. In the furniture which maintains the function and shape of the square-typed table with 3 or 4 layers and the book table in the Joseon dynasty but is used under the different term in the present times it can be counted that display cupboard or bookshelf. Furthermore, desk and tea table can be regarded as furniture which exactly corresponds with the term "table" used in the present days, and also in the Joseon dynasty period there were furniture with such same function as like the writing table and small dining table.

This clinical study is designed to find the characteristics of heat and cold according to Sasang Constitutions by using a statistical analysis. The study was conducted based on the questionnaire sheets and medical history (clinical data) of 1080 people registered at Sasang Constitution Information Bank (SCIB). The total number of people registered at SCIB was 1083; however, 3 Taeyangin's data were excluded in this study. The statistical analyses results on these data were: Most Taeumins have warm limbs, while Soeumins have cold ones. Taeumin, and Soyangin do not like hot weather, while Soyumin doesn't like coldness. As soeumins' body temperature is relatively lower than that of other constitutions, they tend to sleep tightly under blankets or comforters. Taeumin tend to drink more water because they sweat a lot; while Soeumin drink smaller amount of water because they sweat less. Both Taeumin, and Soyangin like cold food, but Soeumin liked hot food. Soeumin showed strong tendency for hot and cold food, while other constitutions displayed less inclination toward the certain temperature of food. Soeumin certainly had the remarkable response toward changes in heat and cold than other constitutions. The differences written above were proved to be meaningful enough by Chi-square test.

The increased availability of portable, low-cost, high resolution video devices has resulted in a rapid growth of the applications for video sequences. These video devices can be mounted in handhold unit, mobile unit and airborne platforms like maned or unmaned helicopter, plane, airship, etc. A core technique in use of video sequences is to align neighborhood video frames to each other or to reference images. For video sequences registration, we extracted interested points from aerial video sequences using Harris, $F{\square}rstner$, and KLT operators and implemented image matching using these points. As the result, we analysed image matching results for each operators and evaluated accuracy of aerial video registration.

Based on the theory that formation of Korean Men's Traditional Trousers is related to Mobius strip, this study researches correlation between distinctive construction of Korean Men's Traditional Trousers and historical background based on old documents and restoration. Distinctive construction of Korean Men's Traditional Trousers are as follows. First, Korean Men's Traditional Trousers is manufactured just like Principle of Mobius strip that the square is twisted once, considering its materials' conditions. Second, Korean Men's Traditional Trousers, manufactured larger, feature cubic effect and twisted formative beauty because its waist and ankle parts are tightened with bands. Third, Korean Men's Traditional Trousers, composed of big Sapok and small Sapok in oblique, are suitable for active play due to its high functionality.

Approximate analysis for a building installed with a friction damper is revisited to get insight of its dynamic behavior. Energy balance equation is used to have a closed analytical form solution of dynamic magnification factor (DMF) for the building with combined viscous and friction damping. It is found out that DMF is dependent on friction force ratio and resonance frequency. Linear transfer function from input external force to output building displacement is obtained by simplifying DMF equation. Root mean square of building displacement is derived under earthquake-like random excitation. Finally, design of friction damper is proposed by processing target control ratio, damping ratio factor, and friction force in sequence.

In this paper, flowfield and acoustic-field around moving bodies are simulated by the Arbitrary Lagrangian Eulerian (ALE) formulation in the finite difference lattice Boltzmann method. Some effects are checked by comparing flaw about a square cylinder in ALE formulation and that in the fixed coordinates, and both agree very well. Matching procedure between the moving grid and fixed grid is also considered. The applied method in which the both grids are connected through buffer region is shown to be superior to moving overlapped grid. Dipole-like emissions of sound wave from harmonically vibrating bodies in two- and three-dimensional cases are simulated.

The area between the arc and chord of a circle is called Hosichun whose figure looks like a bow and an arrow, and had been evaluated by the two formulas $\textit{H}_{n1}$=a(a＋y)/2 and $\textit{H}_{n2}$=3ay/4, where $\alpha$ is the length of the arrow and y the chord of the circle. By the inspection of the area of the Hosichun, some errors of the numeration table in Thurmans S. Peterson's CALCULUS were found easily, that is, the area of the Hosichun is smaller than its subarea in the same Hosichun and perhaps has been to be the worldwide and centurial invalid standard. From now on, the chain proofreadings of the errors will be necessary in our mathematical world. This paper is intended to introduce some such problems related to a circle and another Pythagorean Theorem which is the ratio of the side and diagonal of five and seven In a square.

In Korea, where most of the sites are narrow in space and their earth resistivity is relatively high, the spaces between grounding conductors are likely to be designed narrow in order to lower ground resistance and dangerous voltage below to the permitted safety values. In addition, ground nets are in the shape of square or rectangle depending on the location and size of the facilities and ground contact area, and inner conductors are laid out in grids like the pattern of nets. Nevertheless, with the existing designs, the marginal voltage for safety gets higher as the area is extended further outside, in comparison with that of inner mesh grounding, thus causing much difficulty maintaining them equipotential, and there exist limits in the burial, grounding grid design considering the dangerous voltage of muti-layered model in the constrained sites, was studied.
