Korean peninsula has a long history and a geopolitical location as a buffer tone, which has provided the conditions for cultural dynamism and diversity across space and time. The changing processes of place names in Korea is considered to be better suited to the study on cultural politics that is interested in the culture wars over the meaning of culture among different social subjects. In order to ensure the legitimacy of cultural politics for the study of place names in Korea, this study attempts to make a theoretical construction based on the concepts of place identity, territorial contestation, and the politics of scale. Cultural and linguistic theories to be best applied to the study of place names in Korea are the theories on Angehm's and Castells' identity, $P{\hat{e}}cheux's$ identification, Hall's decoding, and Voloshinov's ideological sign. Power relations involved in the inclusion and exclusion are necessarily concerned with the process of constructing a place identity or territorial identity by means of a place name, which represents identity and ideology of a social subject. In the examination of this process, it is necessary to take the elements of identity, ideology and power relations into consideration. In this study, therefore, the politics of scale is experimented for its applicability in the study of place name in Korea, which is expected to accommodate concepts of boundary, territory, territoriality and territorialization. In the end, it is suggested in this study that a series of basic and interdisciplinary studies on the cultural politics of place names in a range of area should be undertaken along with the enough theoretical knowledge of cultural politics.

This study aims to develop the Korean types of continuing care retirement communities (CCRCs). CCRC is well evaluated as a residence that applies aging-in place concept, which is ideal for senior housing. Recently, in USA the CCRCs in which the increasing seniors' population and older households are guaranteed to get continuous protection without moving regardless of their deteriorating health are increasing. In Korea, CCRCs have emerged but not well developed in status quo. We conducted case study using three facilities located at Seoul and its suburbs in Korea to compare five categories such as application of 'aging in place' concept, location, architectural features, services or programs, and management. This study is expected to be used basic materials for CCRCs' complex and architectural planning, management strategies, and services or programs.

The purpose of this study was to establish planning criteria and development of type for the senior citizen who lives alone in home for the elderly at rural and fishing villages. In order to take most suitable co-housing, this analysis is progressed various building types based on aging in place and aging in health; self care, nono care, service care and community care. This paper is to suggest collective housing with 10 types in large scale and extracted 19 types in detail scale. The basis of classification are location condition; aging in place, building condition, health care condition; aging in health and possession & operation condition. In viewpoint of dwelling welfare 'Home for the Elderly' is to concerned with systematic methodology and architectural typology for senior citizen who lives alone in the rural and fishing village.

Online social networking services help people to migrate social networks from offline to online. Twitter, which has achieved incredible growth, showed that an online social networking service without offline bases can become large and successful. In this paper, we propose a twitter friend notification service using user‘s twitter messages and place recognizing technology. When there is a friend in user‘s nearby place, the service notifies the information to the users. Through the friend notification service, a user can easily extend his online social network to offline.

A fast and accurate building-level visual place recognition method built on an image-retrieval scheme using street-view images is proposed. Reference images generated from street-view images usually depict multiple buildings and confusing regions, such as roads, sky, and vehicles, which degrades retrieval accuracy and causes matching ambiguity. The proposed practical database refinement method uses informative reference image and keypoint selection. For database refinement, the method uses a spatial layout of the buildings in the reference image, specifically a building-identification mask image, which is obtained from a prebuilt three-dimensional model of the site. A global-positioning-system-aware retrieval structure is incorporated in it. To evaluate the method, we constructed a dataset over an area of $0.26km^2$. It was comprised of 38,700 reference images and corresponding building-identification mask images. The proposed method removed 25% of the database images using informative reference image selection. It achieved 85.6% recall of the top five candidates in 1.25 s of full processing. The method thus achieved high accuracy at a low computational complexity.

This study provides an empirical analysis of location competition for demand maximization by central place theory among physicians in nonmetropolitan areas of Korea. The results show that the primary care physicians distribute themselves evenly from urban communities to rural communities. The subspecialists, however, cluster together in major cities rather than decentralize themselves in rural counties. This study establishes the three statistical models : Primary care physicians, subspecialist physicians, and total physicians. Two models of primary care physicians and total physicians have a strong significance in multiple regression analysis (p=-.0001). The primary care model explains approximately 45% of the variation and the total physicians model explains approximately 70% of the variation in physician/1,000 population ratios across national counties. The subspecialist physicians model analysze the tobit regreassion because of the left consored and truncated values(57 cases = 0). In all three models, analysis of the coefficiencts for physician centralization degrees in the 0- to 5- and 5- to 10-km rings around the core county reveals each a positive and negative association betwee these degrees and the physician/1,000 population ratios in the core county. Also, the results provide moderate evidence that the relationship between clinic physicians and community hospitals is competitive, and the relationship between clinic physicians and pharmaceutists is synergistic. This suggests that public policy makers and local self-governing bodies must take an active role to ensure procider availability and the regional health planning in all nonmetropolitan areas of Korea.

This study was prepared for the purpose of restorative consideration such as the construction background, scale, and location of buildings by comparing the historical materials of two countries, Korea and Japan, focusing on Choryanggaeksa. Choryanggaeksa was a building with a special purpose installed in Dongnaebu in the late Joseon Dynasty, and was also a space exclusively for Japanese envoys. When Choryangwaegwan, the only place of diplomacy and trade with Japan in the late Joseon Dynasty, moved in 1678, Choryanggaeksa was also built and continued until its function ceased due to the modern opening of the port. As diplomacy and trade with Japan take place in the category of Choryangwaegwan, the existence of an interpreter takes an important place. Therefore, Seongsindang, a space for interpreters, was built near Choryanggaeksa. When the modern port opened in 1876, Choryanggaeksa and Seongsindang lost their original function, but the building remained. However, after the 1890s, a Superintendent office was built on the site of Choryanggaeksa, and a school was established on the site of Seongsindang. It was destroyed when the site of Choryanggaeksa and Seongsindang was converted during the opening of the port, and its remains cannot be found today due to urbanization.

Workers have been replaced by mobile manipulators for factory automation in recent years. One of the typical tasks for automation is that a mobile manipulator moves to a target location and picks and places an object on the worktable. However, due to the pose estimation error of the mobile platform, the robot cannot reach the exact target position, which prevents the manipulator from being able to accurately pick and place the object on the worktable. In this study, we developed an automatic alignment system using a low-cost camera mounted on the end-effector of a collaborative robot. Camera calibration and pose estimation methods were also proposed for the automatic alignment system. This algorithm uses a markerboard composed of markers to calibrate the camera and then precisely estimate the camera pose. Experimental results demonstrate that the mobile manipulator can perform successful pick and place tasks on various conditions.
