The Ubiquitous City (U-City) spatial information technology aimed to provide services freely anytime and anywhere by converging high-tech information & communication technology in urban infrastructure has been available in diverse patterns. In particular, there have been studies on the development of 3D spatial information after selecting and matching key points with stereo images from the many Closed Circuit TV (CCTV) in the U-City. However, the data mostly used in extracting matching points haven't considered external environmental impacts such as illuminance. This study tested how much the matching points needed to construct 3D spatial information with the CCTV whose image quality is dependent upon changes in illuminance fluctuate under the same hardware performances. According to analysis on the number of matching points by illuminance, the number of matching points increased up to 3,000Lux in proportion to the illuminance when IRIS, shutter speed and ISO were fixed. In addition, a border between an object and background became more distinctive. When there was too much light, however, the page became brighter, and noise occurred. Furthermore, it was difficult to name key points because of the collapse of an inter-object border. It appears that if filmed with the study results, the number of matching points would increase.

We investigated the structural geometry of thirty-eight Korean femurs. The purpose of this study is to identify major geometrical differences between Korean femurs 3nd others that we believe belong to Caucasians so that we would be able to get insights into the femoral component design that fits Asians including Koreans. We utilized computerized tomography (CT) images of femurs extracted from cadavers. The CT images were transformed into bitmap data by using a film scanner, and then analyzed by using a commercially available software called Image v.1.0 and a Macintosh IIci computer.The resulting data were compared with already published data. The major results show that the geometry of the Korean femurs is significantly different from that of Caucasians: (1) the anteversion angle and the canal flare index are greater by the amount of approximately 8˚ and 0.5, respectively, (2) the shape of the isthmus cross section is more round, and (3) the distance between the teaser trochanter and the proximal border of the isthmus is shelter by about 15 mm. The results suggested that the femoral component suitable for Asians should be different from the currently-used components designed and manufactured mostly by European or American companies.

Smart cities are expanding their spatial scope to urban areas and regions. Linking regional economic development strategies beyond the borders with smart city planning can lead to cooperation and economic development between regions and countries as well. The purpose of this study is to suggest cooperation and regional development of the three nations - Korea, North Korea and China - through the Yellow Sea Rim Smart Region. To this end, smart city strategies and economic development plan with implementation status in the three countries including special economic zones have analyzed that could be the spatial basis of the smart region. On the west coast of Korea facing the Yellow Sea, lots of projects related to smart cities are actively underway in Saemangeum, Yellow Sea Free Economic Zone(YESFEZ), and Incheon Free Economic Zone(IFEZ). Although the political situation is still uncertain, North Korea is analyzed to have economic and technical potential in the west coast connecting Haeju, Nampo, and Sinuiju. In Liaoning and Shandong provinces of China, smart city projects have been actively promoted in recent years especially in the state-supporting industrial cities. Restoration of economic cooperation between South Korea and China, linkage of transportation networks, vitalization of cross-border cooperation projects between China and North Korea centered on Dandong and Sinuiju, and the connecting of smart city infrastructure and services for China and South Korea's economic cooperation process will make the Yellow Sea Rim as a world prosperous economic region. However, it is necessary to establish and operate a governance system through long-term planning for transnational consultation and establishment of a promotion organization.

The purpose of this study is to examine the possibilities of use as a factor of the water landscape in modern urban spaces such as parks and, apartments, through a case study of the concept, functions, and culture of moats in the East and West from ancient times to the Middle Ages. This study aimed to examine the concept, origin, and function of the moat as a theoretical consideration. Asian castles with moats, including those in Korea, China and Japan, and Western castles with moats in Britain, France, Belgium, and Germany were investigated and analyzed. By reflecting on these cultures and the functions of the moat in modern urban spaces and converting the environment damaged due to industrialization and urbanization into an eco-friendly and environment symbiotic city the quality of life can be improved, and sustainable development can be achieved. This study was conducted through a literature survey and field investigation.

The existence of coastal terraces, HH(High higher) surfaces found at Gampo of southeast coast and at Jeongdongjin of the central east coast were confirmed at Jigyeong-Ri, the areal border between Gyeongju- and Ulsan city on the southeast coast of Korea Peninsula. Especially this study reports HH JK-surface located on the 155m a.s.l., which is the highest altitude among the ancient shorelines of the coastal terraces in Korea. The HH surfaces on the study area are classified into HH JK at 155m, HH-I at 140m and HH-II at 115m, and each formation stage is related to MIS 17(720∼690ka BP), MIS 15(630∼560ka BP) and MIS 13(510∼480ka BP) respectively. The HH-surfaces remain to be larger than those of H- and L-surfaces. The reason is caused by the unique factors of the coastal geology and morphology on the study area during the formation stage. And also the areal difference by the magnitude of upheaval doesn't exist from north to south because the altitude system of ancient shoreline on each coastal terrace is same along the east coast. The upheaval rate of the eastern coastal areas was measured in the relation to the ancient shoreline and formation stage among the coastal terraces such as HH JK-, HH-I, HH-II, H-III and H-IY surface, and was almost same as 0.23mm/y.

This study is to clarify the effect of changes of cultural industries, specialized products and regional festival, in "Junwon culture region". According to this study, "Junuon culture region", as border region of Koguryo, Baekje, Silla kingdom, which has not constituted its original culture, must develop its own specialized products based on culture and history of the three kingdoms in modern meaning. In 21st century, cultural industry of "Junuon culture region" must emphasize the role of linking of Koguryo culture which consists of major culture in North Korea. Because regional festival of "Junuon culture region" as place marketing is concentrated in spring and autumn, regional festival must be a package type of interregional network. In 21st century, "Junwon culture region" as border region of Koguryo, Baekje, and Silla, must be the peace place of cultural industry with maximized merit and high accessibility at present time. And with development of knowledge and information society, cultural industry estate must bring up regional network centralizing Cheongju city.ng up regional network centralizing Cheongju city.

This study reviews the progress of maquiladora industry in Mexico and the development of the IMMEX program. The maquiladora program allows foreign-invested factories in Mexico to import raw materials and components duty free and to export the finished products to the U.S. It contributed to the increase in employment and population of border cities. Low wage level of Mexico induced not only standardized labor-intensive industries but also the high-tech automated industries requiring assembly process. In 2006, the Mexican government merged the maquiladora program and PITEX for Mexican export-oriented firms into a single new program, the IMMEX program, in order to promote exports more efficiently. This study presents the distributions of the IMMEX firms by industrial sector and by region. It is revealed that transport equipment sector leads the export industries in Mexico, and Tijuana and Juárez accommodate largest agglomerations of the IMMEX firms.

The study utilizes remote sensing as the main monitoring means. With different spatial high-resolution, multichannel ASTER remote sensing image as the main information in Beijing city zone; with regional border and statistical data as auxiliary factor a study between the thermal space distribution character and the underground medium is analyzed based on the GIS logical algorithm and synthetic analysis technology. Results show thermal forming mechanism and the rule of distribution is mainly related to the underground medium and the change of the city distribution. Different underground medium has different degree and intensity influence on the thermal space distribution. Furthermore, urban greenbelt and water areas can reduce the thermal effect and large-scale greenbelt creates green island effect. In addition, Road net, residential area, population density, heat resources and so on have some positive effect on the thermal distribution, which increase the local temperature and intensity on the other hand. It is important to study the thermal distribution and its related factors, which contributes to the plan, construction and development of the city.

Although Incheon metropolitan city is the third largest city in Korea, it is called 'the gateway to Seoul', 'the second city of port', and 'the satellite city'. The people in Incheon as well as other regions unconsciously recognize this city as 'border' and 'periphery' of Seoul through those expressions. These perceptions also develop a negative sense of place about Incheon. This study starts with analysis about marginal landscape images of Incheon in texts such as movies, stories, and geography textbooks. The represented text as movie has a gap between real space and it. Nevertheless, Its strong point is a making problems clear about recognition of reality. I will inquire the origin of senses of place about Incheon through analysis of represented texts. Moreover, I will present the notion of 'flight' that stands on the basis of Deleuze's Nomadism. Here, 'flight' means that the active subject continuously challenges and reforms the nature of periphery and dependency, the capital, and the economic subordination, and it will have to be new identity and direction of Incheon.

In the recent years, there has been attempts to try to understand the urban waterfront in diverse aspects. This article aims to understand basically the port-city's waterfront by the cultural interpretation of it in the basis of the concept of Water Culture. Water has the attribute that put down the border between inside and outside. This attribute of water leads to the attributes of Sea, such as dynamism, collectivity, and openness. The perimetric quality, openness, hybridity, and passage quality of the sea-port city's waterfront are resulted from these attributes of water and sea. These cultural attributes of urban waterfront exert a effect upon the residents' cultural identity of sea-port city. Thus the correlation between waterfront's attributes and the cultural identity should be reflected in the stage that its development is planned.
