This paper presents a technique for real time multiprocessor parallel processing to develop an avionic system computer(ASC) which integrates the avionics control, navigation and fire control, cursive and raster graphic symbol generation into one line replaceable unit. The proposed method has optimal performance by adopting a logically asymmetric structure between four 32bit RISC processors based on the master-slave multiprocessing, a tightly coupled interaction level with the time shared common bus and global memory, and an efficient bus arbitration algorithm. The ASC has been verified through a series of flight tests. The relevant tests also have been rigorously conducted on the prototype ASC such as electrical test, environmental test, and electromagnetic interference test.

This study has set up a plan to establish a trail as a means of maximizing a community by using the residents' living materials and unused facilities that a village holds now. A local archive is a place where the records and living materials collected from a village are preserved, displayed and shared with others, serving as a complex space with multiple functions. To apply the idea of 'utilizing a local archive', the empirical study was conducted by making an analysis of trail resources of Baekryeong Island and local archive application resources. Local archive resources were selected through evaluation of connection of trail routes by investigating and discovering the unused facilities of Baekryeong Island village and the depreciation level and scale of them. And actual local archive living references were investigated and collected through in-depth interviews of villagers. Also, through planning of trails by region, limitations of investigation activities were improved and various tangible and intangible resources owned by Baekryeong Island were utilized to enable effective and distinctive investigation activities and experiences. Unused facilities were surveyed and chosen to take advantage of the local archive space, along with in-depth interviews with the residents living in Baekryeong Island. In addition, the current conditions for the trail routes were checked out in order to 'point out the final routes'.

We make an interference analysis to obtain a critical ctiteria for coexisting availability of WLAN and WiBro between adjacent channels can be used in TVWS(TV White Space). To meet this analysis, we set the various transmission parameters including the emission and blocking mask, antenna height and gain, transmission power and bandwidth, channel model etc. And, based on these parameters, we analyze on performances according to a variation of guard band, a number of service user and allowable transmit power of the user operating in the adjacent channels. In this paper, we consider a urban environment and apply a Extended Hata-SRD for WLAN and an interference link and Extended Hata model for WiBro, respectively. With these results, we can see how each system can be shared in an adjacent channel.

The purpose of this study is to understand modernization process of korean housing during the past one century. To following up the changes of everyday lives of common peoples, magazines, news papers, tourist's records and gossip items were collected and interpreted from the microscopic point of view. In this study arguments on 'modernity' of korean housing was focused on some issues, thus, separation, differentiation, individualization, as well as privatization. Concrete discourses are; firstly, spatial isolation of housing and urban place each other, secondly, functional division of inner spaces of housing, and lastly, guarantee of privacy sphere. Historical changes of housing showed some meaningful phenomena. Before modernization housing was place of reproduction and consume at the same time. However after modern urban space came into existence and work and rest were separated, housing gained only mono function. Thus, housing have only one meaning as private place for nuclear family, that is "Home, Sweet Home." Instead of past multi-functional rooms, functional prescribed rooms, for example, dinning room, were newly born. In the past, the boundary between public and private sphere was not clear. For examples, everyday experiences of family were extended to the street and in the house in most cases spaces were shared. But after modernization the scale of individual spaces become larger and private life can be secured. Consequently, history of everyday life from traditional agricultural society to industrialized modern society demonstrates the structural context between the micro and macro dimension in the fields of human life. In other words, everyday lives and macro history response each other and create new perception of time-space structure in the modern housing.

Cityschumers experience the urban with the visual perception while walking an average speed of 4km per hour. At this time, recognition of the color field accounts for more than 70%. Therefore, in this paper the environmental color of urban street is examined by dividing the pedestrian visual field area. In the urban street, the area of the visual field area of the pedestrian is divided into Ground Plane, Roadside, Canopy and Building Wall. In addition, we observe and color survey the environmental color of Exhibition Road, which is the northern side space of South Kensington in London, which adopted the world's first shared space. The color of the visual filed area was dominated as YR, GY, Y, PB. The Ground Pland was dominated by the YR. The reason for this is that the color of the floor has changed due to the shadows of surrounding architecture and facilities. Roadside was dominated in various ways such as GY, BG, PB, B and P. Canopy was mainly composed of PB, GY, etc. It was found that the material color of the lower part of the architecture was reflected. The architecture wall was affected by the reflectance and absorption rate of the transparent material. The first image that comes to mind when thinking about the urban is the street where pedestrians walk, feel and enjoy themselves. Therefore, it is suggested that various policy frameworks for managing and managing urban planning professionals may be different from the perceptions of pedestrians active in mega cities.

Sharing economy which is sharing and borrowing goods, space, and services as a social and economic activity based on the Internet and smart phones is a new research topic in convergence area. The most representative areas of shared economy are space sharing and vehicle sharing. This paper aims to explore the factors affecting sharing intention of vehicle. We have identified the independent variables which include economic benefit, social benefit, social influence, psychological benefit and perceived risk. We also have done how these variables affect on sharing intention. Unlike Korea, in China vehicle sharing is legally allowed and has a large scale economy. To prove the hypothesis, we performed questionnaire investigation in China and analyzed with SPSS program. The result of hypothesis is the followings: The economic benefit, psychological benefit, social influence and perceived risk are affects sharing intention, and social benefit is not affect sharing intention and sharing intention is affect sharing behavior.

The purpose of this study is to find out users' preference of the shares community space(SCS) for the Community Design. For this, it was analyzed the residents' behavior characteristics of the current multi-family housing and the residents' needs of the SCS. This study focused on seeking out the user-oriented design criteria for the planning of the SCS. The survey was carried out with a structured questionnaire including sketch map from Aug. 13, 2001 to Sept. 14, 2001. The subjects were housewives who's living in Haeuondae of Busan, Korea. Total number of 650 questionnaires were collected and analyzed. Especially 439 cases among them were used for analysis of mental map. The SPSS PC＋ was used for the analysis of data. The results of this study are as follows : First, as to the users' behavior for the SCSs, there is a difference in the location of residents' activities by contents of them. And, the range of these locations categorized according to levels of spacial cognition for neighborhoods. Second, as to the analysis of the SCS through a mental maps, it was shown that the residents' pathway and the residents' location are main variables to be considered in the SCS planning. The preferred location of SCS is organized according to the character of the SCS; the one for most residents, is located the surrounding of main enterance or the center of the housing complex, and the one the neighbors living in the same or the near building is located in area of the block of resident buildings. Third, as the results of residents' needs analysis, the SCS has the meaning of community facilities. And there is a difference in the degree of necessity and in the preferred location according to character of the SCS. In detal, for the indoor SCS of a resident building, there is a difference in the preferred location according to the kinds of each SCS. And for the outdoor SCS, it is necessary to divide the planning zone of the SCS into 3 steps(the resident building, the block of resident buildings, and the housing complex).

Extended Reality (XR), such as virtual and augmented reality, has huge potential for immersive data visualization and analysis. In XR, users can interact with data and other users realistically by navigating the shared virtual space, allowing for more intuitive data analysis. However, creating a visualization in XR also poses a challenge because complicated, low-level programming is required, which hinders broad adaptation in visual analytics. This paper proposes an interactive visualization authoring tool based on hand gesture for immersive data visualization-Gadget Arms. The proposed system provides a novel user interaction to create and place visualization in the 3D virtual world. This simple, but intuitive, user interaction enables user designs the entire visualization space in the XR without using a host computer and low-level programming. Our user study also confirmed that the proposed user interaction significantly improves the usability of the visualization authoring tool.

Scholars have considered Chaucer's House of Fame mostly as an ars poetica, in which the poet explores new poetic principles and subject matters, while making few attempts to understand the poem in its historical and social contexts. Investigating the nature of the "tidings" that Chaucer suggests as the new source of his poetic inspiration, this paper argues that the house of Rumor was modeled after late fourteenth century English society that experienced increased appetite for news. The political upheaval during the period from the English Rising in 1381 to the reign of Henry IV in the early fifteenth century produced an unprecedented amount of written and oral propaganda. The proliferation of seditious rumors as well as protests and promulgations during this period indicates how seriously medieval society was engaged with the circulation of news. Particularly, the case of John Shirle in 1381 and the legend about the survival of Richard II demonstrate the subversive power of medieval rumor that often served as a political discourse with which people expressed their oppositions to government. Conspicuous in the activities of both the government and late medieval political protestors was the extensive use of writing. The posting of bills in public places continued until the fifteenth century, when such activities became so common and dangerous that the government had to issue proclamations forbidding the circulation of such seditious writings. The number of extant royal proclamations, written protests, and pamphlets demonstrates that already in the late fourteenth and fifteenth centuries the notion of a discursive public space began to emerge. Whether written or orally transmitted, news and rumor circulated in late medieval England, creating a social space in which people shared their political opinions before the introduction of the early modern print culture. In The House of Fame Chaucer calls attention to the subversiveness of rumor, its potential as a public discourse, and the power of written communication in creating truth in order to appropriate these characteristics for his English poems.
