The purpose of this study is to analyze the continuous forms of time and space that work as architectural design principles of the Memorial to the Murdered Jews of Europe (Jewish Memorial). Continuity is divided into two, physical and non-physical attributes. The former extends from small installations to furnitures, finishes, spatial composition, and even spatial networks that complete architecture, and the latter is tied to time, from traditional to historical, developmental, commemorative or memorial elements. They are inherent in architecture as continuous forms. The Jewish Memorial is analyzed by the analysing framework of these two items. The analysis of the two layers can be summarized as follows; physical continuity is found in the space networks of the Memorial's inside and outside, the undulating spaces, the finishes, the small furnitures and installations, the entrances of staircases, the expanded underground of the ground order, and non-physical continuity manifests in the topological variation of spatiality, the morphological development of memorial architecture, the connection of semantic sense of space, and the superposition of historicity and modernity. These forms of continuity do not aestheticize the German enormity history, but make the meaning of the Memorial into non-superficial, in-depth architecture as a monument. Thus, the results of this study show that physical and non-physical continuity should be considered as the important design principles of architecture that makes the Memorial architecture possible.

This article attempts to propose the control planning of townscape color around the historic and cultural heritages. The streets and roads of historic conservation and the changing perspectives to which it gives rise in Stockholm has changed dramatically during this century. New development or changes to existing buildings should be carried out in a way which acknowledges its surroundings and is a good neighbour, both in the cultural and social sense that makes good color design sense. There are many examples of townscape color, but the conservative and the historical streets and roads in the whole of the Stockholm city should benefit from careful design of the environment. To achieve this purposes, some strategies of case study of several streets and roads are reviewed; designing color context to relate to urban architectural design proposals of specific sites of cultural heritages are explored. In all new developments the scale of new buildings and the material finishes and colors used should respect the character of their surroundings and have due regard to the setting of any listed building. Streetscape color of visual assessment proposals should aim to help assimilate the development into the local scene. Important streets and roads should also include color townscape.

Purpose: Currently, research on environmental conditions and finishing materials for medical facilities with proven antiviral performance is poor in Korea. Through this study, we have explored environmental characteristics and finishing materials that can be used to control cross-infection when constructing medical facilities. Methods: Experiments in overseas papers related to antiviral effects of environmental conditions, spatial compartments, and interior finishes have been analyzed. Results: The higher the temperature, the higher the humidity, and the higher the illuminance of sunlight, the lower the viability of the corona-virus. The proliferation of viruses was suppressed on the surface of the copper alloy. Materials such as brushed steel are the ones that maintain the strongest viability. Among the characteristics of the surface, survival and propagation power differ depending on whether it is porous or hydrophilic. In the case of infection ward actually operated in Italy, the presence of airborne viruses in contaminated and non-contaminated spaces differed significantly. Corona-virus has been identified in reachable parts such as door handles and medical shelves in quasi-contaminated spaces, which are spaces between contaminated and non-contaminated spaces, but the corona-virus has not been identified in cases of out-of-touch walls. Implications: It is necessary to evaluate the performance by testing the construction finishing materials of infection control facilities according to domestic conditions.

We consider a generalized N-policy for an M/M/1 queueing system. The idle server starts to work with ordinary service rate when a customer arrives. If the number of customers in the system reaches N, the service rate gets faster and continues until the system becomes empty. Otherwise, the server finishes the busy period with ordinary service rate. We obtain the limiting distribution of the number of customers in the system. After assigning various operating costs to the system, we show that there exists a unique fast service rate minimizing the long-run average cost per unit time.

The automatic forming sequence design system can determine desirable operation sequences even if they have little experience in the design of cold forging process. This system is proposed,which generates forming sequence plans for the multistage cold forging of zxisymmetrical solid products. Since the process of metal forming can be considered as a transformation of geometry, treatment of the geometry of the product is a key in planning processes. Forming sequence for the part can be determined by means of primitive geometries such as cylinder,cone, convex, and concave. By utilizing this geometrical characteristics(diameter,height, and radius),the product geometry is expressed by a list of the pnmitive geometries. Accordingly, the forming sequence design is formulated as the search problem which starts with a billet geometry and finishes with a given product one. Using the developed system, the sequence drawing with all dimensions, which includes the proper sequence of operations for the part, is generated under the environment of AutoCAD. The preliminary choice of some feasible forming sequences can verify by using the finite element simulation.

The color planning in the hospital could influence the patient's improvement and lead the users from room to room. This study shows the data of present colors used in the hospitals. In order to get the data, we surveyed and analyzed the current color usages of the present interior of hospitals by the individual data from the projectors. The color scheme is analyzed by the rooms which are the common room, the ward, and the examination room along the projectors. It is also analyzed by the finishes of the hospitals, and is addressed to the present color scheme by the means of the hue value, and chroma. The color scheme in the interior design of hospital is an important factor for the hospital users. It has to more sincerely considered to use colors effectively in the hospital interior since people use their organ of vision greatly when they sense things. According to the data, this study is proposed to the effective color plan which is considered psychologically and emotionally about the human activities, in the interior design of hospitals for the future.
