Architectural color would be understood as a essential tool to be reflected the architect's value criteria, thinking process and the specific methodology. This study was established the characteristics of color use correlated with Eisenman's architectural features based on his point of view. At first, it could be organized with data and use the color in view points with the becomming process. Especially it would be expressed the color as a trace of unsynchronized formation. Second, it was introduced the color by graphics engaged with form, to be expressed the dividing, folding, reiteration for deliver of escape from graphic thinking process. Third, it was analyzed to be imported the color to have a multi-lateral space experience in center of user's space recognition and behavior by introduction of color. Finally, it could be inducted the consistent color by viewpoint of interfacial between interior and exterior environment, communicated with strong meaning by conversion from interior elements to color from these processes. A characteristics of Eisenman's architecture color is reflected his thinking process in architecture color as it is and can be understand of 'becomming process use of color' as a tool that is corresponded in form creation. Specially, it would be kept continuous viewpoint of interior and exterior space, giving user color as a viewpoint of linking space, enable many-sidedness experiences through space.

Metal additive manufacturing (AM) technologies are classified into two groups according to the consolidation mechanisms and densification degrees of the as-built parts. Densified parts are obtained via a single-step process such as powder bed fusion, directed energy deposition, and sheet lamination AM technologies. Conversely, green bodies are consolidated with the aid of binder phases in multi-step processes such as binder jetting and material extrusion AM. Green-body part shapes are sustained by binder phases, which are removed for the debinding process. Chemical and/or thermal debinding processes are usually devised to enhance debinding kinetics. The pathways to final densification of the green parts are sintering and/or molten metal infiltration. With respect to innovation types, the multi-step metal AM process allows conventional powder metallurgy manufacturing to be innovated continuously. Eliminating cost/time-consuming molds, enlarged 3D design freedom, and wide material selectivity create opportunities for the industrial adoption of multi-step AM technologies. In addition, knowledge of powders and powder metallurgy fuel advances of multi-step AM technologies. In the present study, multi-step AM technologies are briefly introduced from the viewpoint of the entire manufacturing lifecycle.

Recently, augmented reality technology has received much attention in many fields. This paper presents an augmented reality system using Rubiks' Cube which can augment various 3D objects depending on patterns of a Rubiks' cube. The system first detects a cube from an image using partitional clustering and strongly connected graph. Thereafter, the system detects the top side of the cube and finds a proper pattern to determine which object should be augmented. An object corresponding to the pattern is finally augmented according to the camera viewpoint. Experimental results show that the proposed system successfully augments various virtual objects in real time.

The cylindrical environment maps of image-based representation methods make high-quality, simple and low-price real-time navigation possible. In this paper, we propose a method to navigate from one viewpoint to the next in the virtual inside space, composed of several cylindrical environment maps. Our system is classified into the two modules. first of all, the panoramic image viewer that employs the rotation and zoom-in/out methods to navigate the virtual inside space, such as the Quicklime VR. The other is smooth real-time navigation using cubic mesh interpolation when the viewpoint moves from one environment map to another in the virtual space.

The cultural identity of design is very critical in the modern society which is called the society of complex culture and multi-culture. In addition, adopting a traditional lattice-like pattern as a composition element of interior space is an effective way in the context of adding a traditional touch to the modern interior space. Meanwhile, in the process of applying Korean traditional lattices to modern interior space, some problems occurred: it has not been properly embodied; or it has been mistaken for those of China and Japan sharing similar culture with Korea. Thus, this study is designed to have precise knowledge of Korea, Chinese and Japanese traditional lattices. Besides, typical patterns of each nation's lattices are comparatively analyzed from the geometrical viewpoint, in a bid to pave the way for th modernization of traditional lattices. In particular, standards are set and proposed to identify different nations's lattices mainly focusing on grid type lattices which are often used and confusing.

The objective of this study is to make the development computer model of a rural village in EumSung-Gun, ChungChungbuk-do. The study district is ChoChon-Ri, WonNam-Myun, EunSung-Gun, and we investigated literature data and field survey in-site at the viewpoint of rural amenity of village unit. The procedure in this study is multi-variance analysis, extract the amenity of the village, make the developing direction, concept planning, and make a computer model.

As for the sheet fed offset printing machine, the research and development of the speedup and multi-color for little rod are done. A charge per one offset printing machine became high year, and all kinds of control device became attach. Under this situation to need, many studies of printability of paper and ink are done. In particular improvement of surface strength of printing paper with speedup is needed. The use of non-wood paper and soybean printing paper with speedup is needed. The use of non-wood paper and soybean printing ink had been increased, study of those printability are important for printing development. From the viewpoint of quality and print important for printing development. From the viewpoint of quality and print productivity, the digital printing machine became lo on the introduction in Japan for the present.

In this paper, an improved detection method is proposed by supplementing various types of Multi-Path gam for a MMSE Multi-User detecter. This method is proposed to complement the shortcomings of the conventional detection method which is used for multiuser detection in STBC(Space-Time Block Code) CDMA system. We analyzed the improved method in bit error probability viewpoint and compared the result with that of the conventional method. In this result, we showed that the improved method obtains better performance of bit error probability than the conventional method when parameters such as delay, number of user and SNR are changed.

Most of previous work on indexing and searching time series focused on the similarity matching and retrieval of one-attribute time series. However, multimedia databases such as music, video need to handle the similarity search in multi-attribute time series. The limitation of the current similarity models for multi-attribute sequences is that there is no consideration for attributes' sequences. The multi-attribute sequences are composed of several attributes' sequences. Since the users may want to find the similar patterns considering attributes's sequences, it is more appropriate to consider the similarity between two multi-attribute sequences in the viewpoint of attributes' sequences. In this paper, we propose the similarity search method based on attributes's sequences in multi-attribute time series databases. The proposed method can efficiently reduce the search space and guarantees no false dismissals. In addition, we give preliminary experimental results to show the effectiveness of the proposed method.

In this paper, an improved protocol of Multi-Link Switching Method is proposed by supplementing a concurrent processing function. This protocol is proposed to complement the shortcomings of the conventional Multi-Link Switching Method which is used for the medium access in LAN. We analyzed the improved protocol in channel utilization viewpoint and compared the result with that of the conventional protocol From this result, we showed that the channel utilization of the improved protocol is superior to that of the conventional protocol when the maximum normalized propagation delay is increased.
