This study investigates the time-space characteristics of the consumptions of cultural-contents commodities and their spatial diffusion progresses via digital media. For the purpose, we examine the spatial diffusion patterns of PSY's Music Video "Gangnam Style" since it has been launched on the YouTube. By visualizing the spacio-temporal progresses of YouTube, Tweet, and Google searching data during four months after launching, we examine the time-space characteristics of diffusion patterns of the music video via each media. We found that the adapting time and the diffusion progress were not in accordance at each country. The results revel that cultural distance such as characterized by language, cultural linkage, exclusivism or courtesy for the 'Hanrue' affects quite strongly on the spatial diffusion of music video rather than physical distance.

This paper provides the results of the investigation on the optimum topology of simply supported deep beam structures with multi-point load cases. In this study, the strain energy to be minimized is considered as the objective function and the initial volume of structures is used as the constraint function. The resizing algorithm based on the optimality criteria is adopted to update the hole size existing inside the material. In this study, the sensitivities of topology optimization parameters to the optimum topology of the deep bean structures is investigated and also the effect of filtering process on the optimum topology is thoroughly tested. From numerical tests, the optimum topology of the deep beam is closely related with the optimization parameters used in the iteration and the filtering process play important role in order to find the optimum topology of the deep beam.

This study is about family discourses of social workers in Korea. The purpose of this study is to gain suggestions of relatedness between discourse and practice by grasping the contents and meaning of discourses in social workers. 10 social workers in various fields were interviewed for this study. The results are followed: First, social workers understand family as a private space which have a meaning of shelter and refuge. Second, there are gaps between consciousness and practice of division of gender role in family. But social workers generally are inclined toward receiving division of gender role in family and applied to their family practice. Third, monolithic family image have a tendency of versatility in family structure, is inclined toward the division of gender role and myth of motherhood. Fourth, social workers perceived emotional tie as important nature of family solidarity and family as natural institution. Also these discourses of social workers were applied to their family practice. The results of this study reveals possibility that social work practice can be discoursive practice or interpretive practice.

This papers is to find out the design theory of total healing environment through the studies on the mutually complementary roles of proxemics, which is the objective and numerical design indicator in the analysis of space and the spacial expression theory, which is the subjective and intuitive design indicator. 3 factors in the elements of total healing environment have the following relationship. And 8 behavioral affordance factors in the elements of spatial expression have the following mutual relationships; The physical factor of total healing environment has the relation with the work&study(+) and circulation(+), the psychological factor has the relationship with the rest(-),visual sequence(-),social exchange(+),refreshment(-) and meditation(-). In addition, the social factor of total healing environment has the relation with the circulation(+),social exchange(+) and community(+). And the work&study(+) and rest(-) of the refuge have the relation with the intimate distance and personal distance, the circulation (+) and visual sequence (-) of the flow has the relationship with the social distance. In addition, the social exchange (+) and the refreshment (-) of the prospect have the relation with the near public distance and the community (+) and meditation (-) of the void have the relation with the far public distance. According to the analysis, the cases in 5 children hospital were studied and the characteristics of total healing environment was evaluated for the spatial proxemics.

The modern age is such an era of time and space compressed. The central axis having compressed the time of the modern Busan city was the very trains and trams. The development of the means of modern transportation, such as trans and trams, came to change the time-space characteristics of cities in the modern age. Through trains and trams regarded as symbols of modern cities, this study attempted to find the localities of Busan as a modern city. The development of the modern Busan city was actually based on modernity and colonial exploitation. Documents of localities provide data to read humans' local-related experiences. 'Documenting localities' related to the means of modern transportation is a work process to read the localities of Busan in the modern age. Through this process, it is possible to understand how means of transportation can be correlated with a local community, local residents' daily lives and spatial change. Overall, this study is such a small attempt for this concern.

The present study purposed to examine the possibility of developing historicity inherent in places into tourism resources from the view that the history and location of historical cities have the nature of cultural contents. Previous researches on tourism have been focused on tourist facilities, the development of tourist attractions, economic effects, cultural policies, etc. However, the present study makes a cultural approach to historical cities to explore the meaning of places formed through history and the historicity of places, assuming that the temporal and spatial characteristics of Hanseong-bu can be developed into tourism resources. Major places of Hanseong-bu are classified according to their functions and cultural meanings, and these factors are associated with the geographical structure of the area. By landform and cultural characteristics during the Chosun Dynasty, Hanseong-bu is divided into the central part, the boundary area, and the outskirts. In addition, different elements, which can be developed into tourism resources, are found according to the landscape of Hanseong-bu, the character as a dynastic city, the environs inside the wall, and differences among localities reflecting pre-modem lifestyle.

Creative environment for sales that a company's image can be effectively delivered to consumers increases consumption desirability and puts confidence in products. Thus, it can be resulted in increasing company's profit. However, nowadays commercial spaces do not show their differences from others due to an excessive competition. Therefore, groping a differentiated composition for commercial spaces should be importantly considered because consumers wants to meet their own individuality in the fashion speciality store. The purpose of this paper is in present the way of differentiating images for commercial spaces. In order to investigate, the role of a wall in commercial spaces should be reconsidered. The concept of a wall in fashion store in the past was understood as one of the structures in the building and a place that displays commodities for sales. However, this paper introduces a new concept of a wall as an important visual function in the fashion store. In other words, the new concept emphasized functions and compositions of a wall in the perspective of symbolic and visual sides, instead of a physical side. Moreover, this paper presents the relationship between the internal side of a wall which has a high frequency of visually and the external side of a wall which has a signaling effect to the consumers. Finally, this paper shows effective way of expressing company's image in the fashion store by adopting the new concept of a wall composition.

The vision-based driver fatigue detection is one of the most prospective commercial applications of facial expression recognition technology. The facial feature tracking is the primary technique issue in it. Current facial tracking technology faces three challenges: (1) detection failure of some or all of features due to a variety of lighting conditions and head motions; (2) multiple and non-rigid object tracking; and (3) features occlusion when the head is in oblique angles. In this paper, we propose a new active approach. First, the active IR sensor is used to robustly detect pupils under variable lighting conditions. The detected pupils are then used to predict the head motion. Furthermore, face movement is assumed to be locally smooth so that a facial feature can be tracked with a Kalman filter. The simultaneous use of the pupil constraint and the Kalman filtering greatly increases the prediction accuracy for each feature position. Feature detection is accomplished in the Gabor space with respect to the vicinity of predicted location. Local graphs consisting of identified features are extracted and used to capture the spatial relationship among detected features. Finally, a graph-based reliability propagation is proposed to tackle the occlusion problem and verify the tracking results. The experimental results show validity of our active approach to real-life facial tracking under variable lighting conditions, head orientations, and facial expressions.

Technological innovations in the 21th Century greatly change the society. The radical advance in computer science brought changes and increased efficiency into society in general. The field of archaeology is also highly influenced and attempts to improve previous manually conducted field survey and research have been actively made. In order to supplement incomplete data set from archaeological excavation, the ways to use computer have been highly explored. GIS is one of them. However, use of GIS has been limited to document locations and to produce distribution map of features using digital map. There are no proper guides to employ GIS for academic research, so that it is hard for beginners to learn how to make use of GIS. In this paper, functions of GIS are introduced even for beginners, including definition of GIS and its archaeological use. It is also explained how to get DEM from digital map to do spatial pattern analysis. Various GIS special pattern analyses using DEM and 3D simulation are presented, as well.
