Existed pattern analysis algorithms in data streams environment have researched performance improvement and effective memory usage. But when new data streams come, existed pattern analysis algorithms have to analyze patterns again and have to generate pattern tree again. This approach needs many calculations in real situation that needs real time pattern analysis. This paper proposes a method that continuously analyzes patterns of incoming data streams in real time. This method analyzes patterns fast, and thereafter obtains real time patterns by updating previously analyzed patterns. The incoming data streams are divided into several sequences based on time based window. Informations of the sequences are inputted into a hash table. When the number of the sequences are over predefined bound, patterns are analyzed from the hash table. The patterns form a pattern tree, and later created new patterns update the pattern tree. In this way, real time patterns are always maintained in the pattern tree. During pattern analysis, suffixes of both new pattern and existed pattern in the tree can be same. Then a pointer is created from the new pattern to the existed pattern. This method reduce calculation time during duplicated pattern analysis. And old patterns in the tree are deleted easily by FIFO method. The advantage of our algorithm is proved by performance comparison with existed method, MILE, in a condition that pattern is changed continuously. And we look around performance variation by changing several variable in the algorithm.

0 and 1, two digits are principle and formality of digital media. Those principle and formality dwell in new media paradigm. They are founded on emergence of new types of space. As describing the relationship originating from the concepts of digital media paradigm and space and discussing their characteristics, this paper presents the grounds for a theoretical argument for formation of new space. The concept of virtuality which mimics and represents the real, non-linearity which resembles human system of thinking and sensing, and interactivity connecting the communication theory of human and machine, their properties form the important basis for emergence of a new aspect of space. The concepts of digital media paradigm divide a type of space into two properties. The first is a inner modality. The second is outer modality. Dynamic space implicates inner modality that humans internally recognize the sense of space through their body and sensing organs. Space is not sensed but sensing. Space has an organic nature through object's interaction. Space has an outer nature that is physically variable. Finally, space has properties of modularity that changes structure of space. For empirical basis of an argument, new media art that has architectural form and those spatial characteristics were compared and analyzed. This conceptual discussion for space which the formality of digital media is applied will be an important foundation for create space design.

Electric components equipped with naval shipboards must endure mechanical shock caused by various mechanical impulsive sources. Thus the components must be designed carefully and reliability test is an essential procedure before use. In this study, a new design technology applicable to a large and heavy shock generation system which can generate various specific real mechanical shocks in specified time domain was introduced. Commonly, the shock transmitted through the wall of naval shipboard consists of dual shocks. The primary shock is of a very high amplitude and very short period half-sine form. The following shock is of an exponentially decaying harmonic form of relatively longer period. Based on the different dynamic characteristics of two shocks, we proposed a sequential design procedure to determine spring and damping coefficients of the generation system. Some numerical simulation results showed the feasibility of the proposed method.

The convergence paradigm that appears with the integrated media environment has effect on digital storytelling using digital technology, then 'Trans-media storytelling' which is a new form of digital storytelling makes gradual expand its scope. This study focused on the Alternative Reality Game which adopt trans-media storytelling in the game genre. This paper interpreted the idea of ARG on comparing different forms of ARG and existing games and the distinctive features of ARG storytelling which is blurring the line between real and virtual on the Simulation theory. This is a valuable study for understanding the new storytelling form within the media convergence and developing the digital storytelling in the future.

In this study, the prediction method of coolant flow rates has been developed and applied to an engine and vehicle cooling system. The flow rate passing through each component of the system is very important parameter to evaluate the heat transfer process form the combustion gas to the coolant and the heat rejection process form the radiator /heater to the ambient air. However, the present study reveals that the measurement using the flowmeter fails to give practical flow rates due to its additive resistance. In contrast, the present method which uses the parallel and serial relationship of flow resistance proved to be a good tool to predict the real flow rates. It can be also used to design the cooling system in the incipient stage of engine/vehicle development . The procedure was coded to the computer program so as to use it flexibly and, in the future, to expand it into an independent design tool of the whole cooling system including the heat release and rejection.

This study is aimed to specify the meaning of the body and the design trends in contemporary architecture. Architecture is based on the human life of various meaning, events, experiences, images, senses and interactions through the body. Thoughts, behaviors, and senses of human are interrelated in architectural experiences. Individuals experience the built environments and space, not through the ideas but through the senses and movements of the body. So, bodies make the real space of architecture. Contemporary architecture accepts the theory of phenomenology and places on the thoughts of Maurice Merleau-Ponty, Heidegger, Nroberg Schulz and so on. Such researches effect on the architectural trends to make design processes works on the programs in views of the expansion and the structuralization of human body. In detail, the aim of this study is to analyse the architecture as the fields of the subject with body as the center, design processes and principles changed form metaphysical thought to phenomenological discourse, and the design trends in contemporary architecture at last. In process of movements, vision centered architecture moves into the bodily experienced architecture and changed the trends from absolute form design to design of relative processes. In conclusion, architectural formation-dissolution-reconstitution of body creates the architectural thoughts such as human proportions, perspective space, ergonomics, modular, organic architecture, experience space, synesthesia, event architecture, fashion-invoked architecture, interactive surfaces, metamorphosis, and others.

This paper examines the pastoral ideal and its legacy to landscape design. We have had the routine convention of experiencing natural beauty from the picture-like nature. We, who would liken a scenic view to a picture, often equate natural beauty with superficial representations of nature shown in pastoral literature and traditional landscape paintings: the lush of towering trees, the field of endless green, the soft babbling flow of the river and the crisp clear sky. It is not a portrayal of nature as it is, but in fact a conceptual expression of its ideal form. The ideological root of that natural beauty can be retraced to the pastoral ideal, so eagerly longed for by people of the western world. A pastoral landscape graciously marked with leisurely peace and subtle harmony is what we identify as beautiful nature. In fact, however, it is no more than an artificial refuge in contextual isolation from its surrounding, and a by-stander's nature seen purely through the eyes of the outsider. The tradition of pastoralism, reaching its peak in the 18th century with its English Landscape Garden style, was transplanted into the real world through the practice of landscape architecture. Landscape design in such a form is just a static means of decoration devoid of meaning and process. And we simply identify the green ornamentation with nature.
