As smart tourism is gaining more attention, there are increasing attempts to make use of augmented reality(AR) in tourism industry. However, existing AR-based tourism contents are only limited to the 'designated' cultural heritage, overlooking the value of undesignated cultural heritage lost in the past few decades of development era. This hinders expanding the scope of tourism contents and leads to the production of banal and similar contents. Given that, our study has developed tourism contents based on , an AR-based mobile application that enables participants to virtually visit the historical sites lost in the development era. The Chungmuro area, which the app is named after, is unique in character. The area has been famous for movie making for over 30 years until the '90s. It is abundant with movie-related cultural resources such as theaters and print shops, which makes the place where people wants to feel the glorious past. Through the app, participants are able to walk along the historic trail and take pictures at five virtual historic spots, among many others. We also examined participants' level of satisfaction and overall tourism experience. By taking the result into account, we hope that the AR-based tourism contents will increase in the future.

Introducing International Style, P. Johnson and H. R. Hitchcock gave three standards to be the Modern, volume and surface, regularity, and exclusion of applied decoration. In spite of the negation of stylistic, formal approach in the Modernist Manifestoes, one usually have understood Modernity in Architecture with its formal character, especially with no ornament and flat, abstract, white surface. Modernism as a new paradigm in architecture have emphasized that there is no representation of anything outside and only present architecture in itself. They said that Modernism only cared about the language of Architecture without figural reference. So apparently there is no way to prove to its Modernity with formal condition. Modernity is in Spirit and contents. But actually we understand well its existence by visual communication This study deals with this difficult situation how Modernity represents itself without visual media and asks the question how simultaneously it presents its thingness and materiality In order to analyse contradictory situation between representation and presentation in Modern Architecture we need to survey the historical process of changing position of ornaments and its meaning in time. With the crisis of representation the role of ornament have seriously changed and divided. It caused the two situation in pre-Modern Architecture. Firstly, Architecture tend to be a high art and formal expression became important much more. The Use of Ornament became a kind of fashion to show the power, class, money. Secondly, Ornament lost its cultural weight and the structure and material aspect became the central in architecture. Rational Structuralism would be the essential character in Modern Architecture. Here the theory of G. Semper and A. Loos on cladding(dressing) and Ornament can help its problems and limits. In the situation without conventional ornament Modernists need to present modernity with new media that only show the thing itself and by that it does not represent any thing else as like the value, idea outside buildings. They believed that only it concerned esthetics and morality in architecture. But in reality it referred to art and machines as like ships, aircraft, and cars. By excluding Ornament and showing the process of clearing, abstract, flat, white surface 'represent' Modernity by the indirect way referring the concept of transparency, reason, sanitation, tectonics, etc. An Ideology and myth intervened architectural discourse to make the doxa about the representation in Architecture. Surface must be a different kind of media and message that can communicate in different way with compared to conventional Ornament. Decorated Shed by R. Venturi and Post-Functionalism by P. Eisenman, that are the most famous post-modern discourse, shows well difficult and contradictory condition in contemporary architecture concerning representation and form, meaning and form.

This paper introduces the modified VaR which takes into account the asymmetry and fat-tails of financial asset distribution, and then compares its out-of-sample forecast performance with traditional VaR model such as historical simulation model and Riskmetrics. The empirical tests using stock indices of 6 countries showed that the modified VaR has the best forecast accuracy. At the test of independence, Riskmetrics and GARCH model showed best performances, but the independence was not rejected for the modified VaR. The Monte Carlo simulation using skew t distribution again proved the best forecast performance of the modified VaR. One of many advantages of the modified VaR is that it is appropriate for measuring VaR of the portfolio, because it can reflect not only the linear relationship but also the nonlinear relationship between individual assets of the portfolio through coskewness and cokurtosis. The empirical analysis about decomposing VaR of the portfolio of 6 stock indices confirmed that the component VaR is very useful for the re-allocation of component assets to achieve higher Sharpe ratio and the active risk management.

In early Josun(朝鮮) era, the scholars, genteels, and high officials in Josun dynasty paid attention to Sijo(時調) who hoped Josun society would share Confucian values. Sijo poems written by them are based upon Confucian ideology, giving an opportunity to its members to make sure their homogeneity and helping Josun dynasty sustain its regime. Gyongichega(景幾體歌) has, however, already failed to be an appropriate genre to do these functions. Nevertheless, in the late Josun dynasty when there were agitation in class hieracy, development of currency economics, maldistribution of wealth, and pursuit of enjoyment, obscene poems turned out. Consequently these songs contributed to encroaching and eventually destroying the Josun dynasty. The question that who are in charge of creating and enjoying Sasulsijo(辭說時調) cannot be answered by approaching it in the social class point of view. The range of the maker or the reader of Sasulsijo in the late Josun dynasty was much more extensive than that in the early times. Not only aristocracy or the middle society but even some of the lower class may have made and enjoyed those songs. In the meantime, it is singer-songwriters whom Park, Hyogwan blamed for their profiteering abuse of obscenity that is supposed to have been mainly reponsible for the creation of those songs. Siga is a double-edged art in its essence--the good and the bad. The lewd songs were, in the early Josun, strictly controlled but in the late Josun dynasty, were thriving due to social changes. In this context, songs based on Confucian ideology as well as the ones focused on sexual love became decayed along with the collapse of the Josun dynasty. Even though, in the light of the history of Siga, those two types of Siga are underestimated in its artistic value, they have very special social historical meaning in doing positive and negative functions for existence and destroy of the Josun dynasty.

The Toyo Bunko (東洋文庫) in Tokyo, Japan is one of the largest library that holds the Korean old geographical documents. About 200 topographies of counties and prefectures, including Giinhansangnyang 杞人間商量 which recorded compilation and improvement plan of the geographical annals belong to it. Several maps and geographical annals of Joseon Period possessed in the Toyo Bunko are set high values on geography since the materials are only belong to it and have not yet been found in Korea. There are very important map collections including six copies of Daedongyeojido 大東輿地圖(1861, 1864) by Kim Jeongho(金正浩) and Suseonjeondo 首善全圖 by Kim, Jungho, collectible stamp of Maema Kyosaku(前間恭作) is imprinted on it, and Gangyeokjundo 疆域全圖 and Dongyeodo 東輿圖 which made with 20-ri and 10-ri grid, owned by Sidehara Daira(幣原坦). Especially Gwanbukjido 關北地圖 which is the northern border map recorded the Lee Sam's(李森) preface who served as a military official of Hamgyeong and Pyeongan Province in early 18th century. These maps and some other maps have a historical value to supplement of the history of Korean Cartography.

The time-dependent evolution of disk mass for outburst limit cycle in a black hole microquasar is calculated based on the non-linear hydrodynamic model of thermally unstable accretion disk. The physical parameters such as black hole mass, disk size and mass transfer rate are adopted to reproduce the historical 1975 outburst observed in a prototype black hole X-ray nova A0620-00. The time-dependent effect of irradiation from the central hot region to the disk is considered in two ways: direct irradiation and indirect irradiation reflected from hot accretion flow above the disk. The accretion disk thermal instability model can account for the bolometric luminosity appropriate to typical characteristics of system luminosity observed in X-ray transients during the whole cycle of the outburst evolution. The maximum mass of the accretion disk, ${\sim}4.03{\times}10^{24}g$, is achieved at the ignition of an outburst, and the minimum value, ${\sim}8.54{\times}10^{23}g$, is reached during the cooling decay to quiescence. The disk mass varies ${\sim}5$ times during outburst limit cycle.

During the 1980s, Textile design achieved a remarkable growth in creating aesthetic effect and in establishing its standing by responding to demands of the time effectively and seeking changes proactively. This was a period when Textile design constructed its modern concept as it was attempting a qualitative improvement through advanced technology, high class, and differentiation. The advent of advanced materials through the development of textile engineering, employment of craft techniques to further cultural and artistic orientation, and restoration of decorativeness in pursuit of sensitivity, all these developments of the 1980s contributed to the rise of above characteristics. In this study, attempts are made to grasp the new trend of Textile design during the 1980s and to review diverse methods of aesthetic creation and plastic possibility which this trend presented for the Textile, and thus to recognize the role of Textile design and its importance in a new light. The new trend of Textile design during the 1980s can be summarized as follows: 1) An appreciation of the creative aspect of the Textile. As attempts are made to emphasize visual and sensitive aspects of the medium, Textile tended to become an object of art itself. 2) A new awareness of the representative and plastic capacity of the fiber material. As attempts are made to develope the creative potential of the Textile, representation of the material tended to become more diversified. 3) A recognition of the Textile as a proper means to deliver the spirit of the time. As the medium accommodates and fuses diverse cultures including traditional culture, more emphasis was place on cultural contents of the Textile. In the process of pursuing these changes, Textile design of the 1980s has also contributed to the creation of new values, laying the groundwork for its emergence as an advanced high value-added industry.

The congestion of railway vehicle and station shows up to 220%. Especially, transfer resistance of passenger increase rapidly by the collision of circulation. So increment of travel time, occurrence of safety accidents act as a factor that inhibits the utilization of urban railway station. In this paper, to improve traveling speed and comfort of urban rail passengers, urban transit passenger guidance system using congestion management model is proposed. The congestion management model that can mitigate a recurring/non-recurring congestion is constructed and the preliminary design of the system (middleware system, control system, guidance drive system) is carried out. Passenger Guidance System is configured by step for changing the external data into a form usable by the algorithm, step to perform the congestion management algorithm using the real-time data and historical data, step to control device based on the value that is calculated by congestion management algorithm, step to drive the device based on the information in the control system and circulation guidance devices. In the future, detail design will be performed based on the preliminary design. A prototype of the various devices according to the station structures and locations will be made. The control module of guidance device will be developed.
