제주도 연악해역의 해일재해의 현황을 파악하기 위하여 제주도 연안해역의 폭풍해일과 기상조에 등에 의한 해일발생 및 피해의 자료를 분석 검토하고 제주도 연안해일의 위험도를 분석하기 위하여 제주도 연안해역을 대상으로 과거 태풍 중 각종 기록경신과 많은 피해규모를 준 태풍들을 대상으로 바람장 및 해일고를 분석 검토하여 태풍의 진로에 따른 해수면 상승을 산정하기위해 폭풍해일 수치모형(POM) 실험을 실시하여 폭풍해일고를 산정하였다. 제주항과 서귀포항 주변해역의 폭풍해일고를 산출하기 위해 16년간($1987{\sim}2003$)까지의 우리나라에 영향을 미친 태풍 중 8개를 선정(Maemi, Rusa, Prapiroon, Olga, Yanni, Janis, Gladys, Thelma)하여 폭풍해일고를 산출하였다. 수치모의 한 결과를 보면, 제주와 서귀포 연안해역에서 발생한 8개의 태풍에 대한 폭풍해일고의 발생시각은 대체적으로 관측된 해일고의 발생시각 보다 약간 늦게 해일이 발생하였지만 전체적인 해일의 시간변화나 크기는 비교적 잘 재현된 것으로 나타났다. 제주항 연안해역의 서귀포항 연안해역보다 높은 해일고를 보였으며, 해일고는 제주항, 서귀포항 모두 1m를 넘지 않았다. 제주항이 서귀포항에 비해 약간 높게 나온 이유는 태풍의 위치, 지형 및 수심, 태풍이 통과할 당시의 조석상황 등의 차이인 것으로 사료된다. 또한, 제주항과 서귀포항 연안해역이 폭풍해일고가 서해안이나 남해안에 비해 작게 나타났는데, 이는 제주도 해안선이 비교적 평탄하고 평행하게 이루어 졌으며 남해안에 비해 수심이 깊고 만의 형태나 V자형 및 긴내만이 발달한 지형이 없기 때문인 것으로 사료된다. 보다 정밀한 예측을 위해서는 정밀한 수심자료 및 격자를 이용한 계산의 결과가 필요하며, 연안개발로 인한 지형과 수심변화에 따른 지속적인 수치해도 DB구축이 요구된다.

In this research, to get over restrictions of a field expreiment, we modeled a planning road through the 3D Virtual Reality and achieved data about dynamic response related to sector fluctuation and about driver's visual behavior on testers' driving the Driving Simulator Car with Eye Camera. We made constant efforts to reduce the non-reality and side effect of Driving Simulator on maximizing the accord between motion reproduction and virtual reality based on data Driving Simulator's graphic module achieved by dynamic analysis module. Moreover, we achieved data of driver's natural visual behavior using Eye Camera(FaceLAB) that is able to make an expriment without such attaching equipments such as a helmet and lense. In this paper, to evaluate the level of road's safety, we grasp the meaning of the fluctuation of safety that drivers feel according to change of road geometric structure with methods of Driving Simulator and Eye Camera and investigate the relationship between road geometric structure and safety level. Through this process, we suggest the method to evaluate the road making drivers comfortable and pleasant from planning schemes.

In this paper, the news coverage of Chosun Art Exhibition(鮮展) in the Japanese occupational era were analyzed by the discourse analysis technique. Japan was advocated the slogan of 'escape from the asia go to the west' and calls itself as western civilized nations during Japanese occupational era. Japan's colonial rule in Asia has created a Japanese orientalism that Japan is considered as developed, and the other Asian countries are considered underdeveloped countries. The media discourse of Chosun Art Exhibition make to believe that the 'backwardness' of Korean local color arts, unlike the 'colonial superiority' of Japanese arts. In the analysis of the newspapers, Maeil Shinbo and Donga Ilbo, Japan recognize Korean arts as the 'assimilation' of Japanese arts, but with the other hand recognize the 'exclusion' of Japanese arts had a dual-in. Especially, Donga Ilbo has a vision of orientalism on the one hand and has a nationalistic perspective on the other hand.

Rapidly changing 3D rendering technology is expanding its fields of display fast towards Non-Photorealistic Rendering beyond Photorealistic Rendering. It is now attainable to realize conventional 2D visual animated cartoons with 3D animation technology. It is not complex to create two shades of color or more with the rendered outcomes, made by Toon-Shading, of 3D total packaging animation Maya with black outlines brought through the process of 2D animation. It the reality of 3D animation being one of the prevalent mechanisms of animated films, it is valuable for familiarized animated cartoons to be realized by the technology of 3D animation. Thus, I hope to help in many ways create more effective 3D cartoon animation production process by optimized Toon-Shading attributes method and technology in this research.

In order to investigate the soil disturbance induced by anchor-shoe for PVD installation and the anchoring mechanism, a new two dimensional testing system was developed. By using the developed testing system, 1g and centrifuge model tests were performed, simulating the driving-retrieval process of both conventional symmetric anchor shoe and new asymmetric anchor shoe. Various size anchor-shoes were simulated and the results were compared. The images recorded during the installation were analyzed by image processing technique. The results of the image analysis presented the clay disturbance depending on the size and type of anchor shoe. In addition, from the retrieval process, the anchoring mechanism was revealed and the holding capacity was measured. As results, the size of anchor shoe influences the soil disturbance and holding capacity. The new asymmetric anchor shoe reduces the soil disturbance and improves anchoring performance.

This study deals with the issue of actual HCI design embodiment through the investigation on how to interpret and use visual expression means in HCI design in a semantic way. The purpose of this study is to provide the method by which designers can make the user-centered guidelines in HCI design. As a part of the user\ulcornercentered design approaches, this study is based on the understanding of user group types which are divided by his/her extent of exposure to computer especially and is focussed on applying the level of each group's apprehension of visual expression means to the embodiment of HCI design. Major findings of this study are: First, it proposes the 'Visual Tokens Models' as a basic source for the understanding and the embodiment of visual expression means in HCI design; Second, it has examined the correlations between the characteristics of Visual Tokens and user group types that is, naive users, casual users, and expert users; Third, it proposes guidelines for the user-centered embodiment of HCI design in accordance with the correlations.

This study is on the application of TOPMDEL(Topographic based hydrologic model) Which is a distributed rainfall-runoff model to the flood runoff analysis. The test area was Wichun experimental catchment site which is mountainous mid-area (Dongok, 33.63$\textrm{km}^2$ and Goro, 109,725 $\textrm{km}^2$) and being operated by the Ministry of Construction and ransporation. A three-dimensional digital elevation model(DEM) map was constructed using a physiographic map(1/25,000) and GIS software, Arc/Info, was used to the analysis of geofraphic factors. The topographic index of Dongok and Goro subcatchment was similar. As a results of the analysis, the model was validated that the simulated peak flow of a flood runoff was fit to the observed data. For the analysis of the effects of grid size, Dongok subcatchment was divided into 100,120-,240 m grid and Goro subcatchment was divided into grid and 120,200,350 m grid. It was shown that the peak flow increased in proportion to the increases of the grid size, but peak times were constant regardless of the grid size in both of the watershed.

Since the early 20th century photo based art and effort to creative experiment, to pursue the essence of creation to escape from stereotypes between form and media, expression and technology, has been continued persistently. Photomontage was born as an artistic attempt for the new representation. Basically photomontage is configured to visually emphasize the message as a work to produce new meaning by combining the various images that are intentionally selected. The photomontage as a visual art, dialectic of text and image that is to pursue a new format to be out the concept already existing, have been developed, the concept is similar to the modern multiple art. The value of photo montage is to explore of the photo, not limited to describe or reproduce as a deformation, the new possibilities for creative expression and the experience of the day-to-day operation for the implementation of the scheme.

Advances of digital device technology such as digital cameras, smart phones and tablets, provide convenience way for people to take pictures during his/her life. Photo data is being spread rapidly throughout the social network, causing the excessive amount of data available on the internet. Photo retrieval is categorized into three types, which are: keyword-based search, example-based search, visualize query-based search. The commonly used multimedia search methods which are implemented on Smart TV are adapting the previous methods that were optimized for PC environment. That causes some features of the method becoming irrelevant to be implemented on Smart TV. This paper proposes a novel Visual Query-based Photo Retrieval Method in Smart TV Environment using a motion sensing input device known as Kinect Sensor. We detected hand gestures using kinect sensor and used the information to mimic the control function of a mouse. The average precision and recall of the proposed system are 81% and 80%, respectively, with threshold value was set to 0.7.

Records, especially the authentic records the nation secured, have an ontological feature of proof that is able to persuade the current present of the past present, and inherent in it is faith that originates from fundamental objectivity. Therefore the image of silence that such strictness of records creates realizes the detonation of specific memories through the act of visual exhibition. This research started from the notion that records achieve social vitality and return through its exhibition, as well as the critical awareness that it 're-mediate' the past and memory through interactions with image. The reason for viewing the archival exhibition as the subject of user analyzation is that in the process where exhibition sorts and arranges records, it is the tool and mediation that most distinctly exposes the identity of the archives. Hence, this research first analyzes national archives, particularly the exhibition of "presidential" records, which is in the center of memory conflict, in the viewpoint of the cultural practice of memory. Afterwards, it discusses empirical research and results on how users accept and resist the meaning of the exhibition through actual surveys of users after their viewing of an exhibition.
