This study attempts at prototyping and evaluating a geovisualization tool that summarizes and explores human activity patterns using spatio-temporal trajectory data collected from GPS receiver. A set of core conceptualization developed in 'time geography' is successfully represented by our prototype based on the notion of 'space-time cube.' The notions of 'temporal dispersion cylinder' and 'parallel plane plot' are also implemented to allow funker analyses of human activity pattern on the space-time trajectory. The capabilities of the geovisualization environment we proposed include the interactive and dynamic functions that support a variety of explorations on the three components of spatio-temporal data : space(where), time(when), and object(what).

The purpose of this study was to explore the possibility of creating barrier-free exhibition-appreciation environment based on the visually impaired person's perspectives. Participants were selected by the purposeful sampling method. Researchers conducted a couple of in-depth interviews with four visually impaired persons. Yin's case study method was employed to analyze qualitative information. The analysis revealed nine sub-themes in two sections: three from 'accessibility within the exhibition room'; and six from 'demand for immersive exhibition environment.' Based on the results, following suggestions were presented: First, we need to provide quality information appropriate for artworks-appreciation; secondly, to ensure the visually impaired people to appreciate the culture and arts without any barrier, we need to extend certification of barrier-free living environment to exhibition-appreciation area. Finally, to facilitate these two tasks we need to encourage the convergence research among science and technology, humanities and society, and culture and arts.

Public Service Advertising(PSA) is the integrated marketing concept including strategy and technology in all its aspects that pursue the changes of community to seek an agreement of its members by the intentional and the target oriented way. PSA to the exclusion of commercial intention reflects the current social flow and subject since it is focused to the social issue. PSA plays an important role in creating the further cultural value, and also affects present cultural value to advertising message. In this aspect, this study is very valuable to design the plan for further effective management of advertisement and to analyze communication strategy of PSA. This study is to make dear the nature of PSA by the analysis of contents of visual image and linguistics' factors in actual produced and broadcasted TV advertising, called 'Protection of environment' In the results, PSA related the environment is working to linguistic-centered persuading message corresponding to visual factor, this intends to educate and instruct the consumers in 1980's. PSA, therefore, shows a non-description nature without story line and a hero(heroin) on it. In contrast, after 1990's, PSA was made up image-centered and maximized the effectiveness public campaign through the activating consumer's judgement and intervention. We are able to know that it contributes to considering and persuading the consumer to suggest the story format through the visual way to deliver the message. This study of relationship between visual image and linguistics is a common trend appeared in all media including today's advertising, and may be a remarkable result to present proper direction of PSA campaign.

In web environment, we accept most of useful information visually. Icon is a channel through which we explore information, and we need icon design to deliver information clearly and quickly to users who accept information visually. Studies on icon have been carried out vigorously according to system environment, styles and characteristics of users. This study is on the metaphor icon, and judging from the characteristics of metaphor icon, it is by the phenomena of user's association of ideas. Divide metaphor and simile and analyzed metaphor icon that is searched in World Wide Web to distinguish similarity in metaphor icon special qualify, And I clarified the present condition of cognition by questionnaires asking people if they recognize the function. I also clarified if elements of icon design influence the level of user's cognition by visually comparing icons. The result of comparative analysis showed that different elements make different level of user's cognition, and to objectify it more, I made up questionnaires about elements of icon design and proved it again. To summarize the result of this study, the similarity between function and elements of design increases the level of recognition of metaphor icon proportionally. To improve user's cognition, I suggest designing with elements which materialize functions.

본 연구는 환경예술운동의 선구자격이며 가장 대표적인 작가로 평가되는 로버트 스미슨의 작품에 대한 연구를 통해 그의 경관미학의 개념화에 대하여 고찰해 보고자 하였으며 궁극적으로 본 연구가 환경예술운동이 현대 조경설계에 미친 영향에 대한 기초 연구라는데 본 논문의 의의를 찾고자 한다. 스미슨의 작품이 조경에서 다루는 경관의 여러 가지 관점을 다루었으며, la국을 중심으로 조경설계에서 공간의 시각적 표현을 시도한 몇몇 조경설계가의 작품배경 또한 환경예술로 불리어지는 일련의 작품군과 작가의 주장에 많은 영향을 받았음에도 불구하고 그의 작품이 조경분야에서 연구의 대상으로 활발하게 다루어지지 못한 것도 사실이다. 본 연구에서는 스미슨의 경관미학의 개념화를 그의 작품을 통해 살펴보았으며, 스미슨의 작품과 조경설계와의 연관성, 그리고 현대 조경설계에 미친 스미슨의 공헌등을 조명해 보았다. 스미슨의 초기작품들은 개발로 인한 환경 및 경관의 남용 혹은 황폐화에 대한 비평적인 관점을 예술적 형태로 묘사한 반면, 후기 작품들에서는 환경 및 경관에 대한 예술적인 조작에 긍정적인 가치를 부여하고자 한 것이었다. 스미슨의 작품이 현대 조경에 미친 가장 큰 공헌은 무엇보다도 경관 및 환경의 변화에 영향을 미치는 수단으로서 예술을 활용했다는 것일 것이다. 환경예술가들의 주장과 그들의 작품이 현대 조경설계에 구체적으로 어떻게 형상화되었는지에 대한 연구는 앞으로 규명되어야 할 부분이라고 판단된다.

This paper discusses about the development of a visual sensor that can be installed in an automatic mooring device to detect the berthing condition of a vessel. Despite controlling the ship's speed and confirming its location to prevent accidents while berthing a vessel, ship collision occurs at the pier every year, causing great economic and environmental damage. Therefore, it is important to develop a visual system that can quickly obtain the information on the speed and location of the vessel to ensure safety of the berthing vessel. In this study, a visual sensor was developed to observe a ship through an image while berthing, and to properly check the ship's status according to the surrounding environment. To obtain the adequacy of the visual sensor to be developed, the sensor characteristics were analyzed in terms of information provided from the existing sensors, that is, detection range, real-timeness, accuracy, and precision. Based on these analysis data, we developed a 3D visual module that can acquire information on objects in real time by conducting conceptual designs of LiDAR (Light Detection And Ranging) type 3D visual system, driving mechanism, and position and force controller for motion tilting system. Finally, performance evaluation of the control system and scan speed test were executed, and the effectiveness of the developed system was confirmed through experiments.

The purpose of this thesis is to suggest objective basic data for the environmental design through the quantitative analysis of the visual quality included in the physical environment of forest landscape. For this, landscape values of forest landscape have been evaluated by using the Iverson method, the images structure of forest landscape's main utilizing space have been analysed by the factor analysis algorithm, degree of visual preferences have been pleasured mainly by questionnaries and SBE method, and finally these thesis can be summarized as fallow LCP with high values of Iverson factors I and IV yield high landscape value. Specifically, Iverson factor IV has been found to play the dominant. For all experimental points, significant seasonal variations in S.D. scale values have been observed. In natural parks, where artificial structures are complementary to the natural landscape, main factors of image are S.D. scales such as the visual sequence, the formal simplicity of structures, the emphasis, the unification of heterogeneous factors and the assimilation. Factors covering the spatial image of natural parks have been found to be the overall evaluation, the individual characteristics, the tidiness, the potentiality, the dignity, the intimacy and the space volume. For all seasons, factors such as the individual characteristics, the dignity, the tidiness, the potentiality, yield high factor scores. As for factors determining the degree of visual preference, variables such as the summit, the skyline, rocks, the water and the degree of natural destruction by artificial structures yield high values for all seasons.
