The Korean miracle of economic growth or development has been quite well known across the world up to now, while being subject to theorization of its model. Compared with this, however, it is quite surprising to see how little about the spatial aspect of Korean development has been exposed in the field of development studies. In fact, for Korea, competent regional policy has turned out to be an important success factor for the spatial upgrading of a low-tech growth regime into a hi-tech one. This paper dissects Korea's regional policy experiences in three aspects from which it draws up a three-tier lesson. The first aspect is the conventional (overall) regional spatial upgrading policy of a developmental regime put in place since the 1960s onwards. The second is the new regional policy tailored to the regionalization of technological and industrial diffusion for new knowledge-based economy. The third is the prospective regional policy for the future advancement of the Korean economy.

In this paper the key drivers change for cadastral organizations have been presented according to the following aspects; Geo-ICT development including positioning technology, government's public organization innovation policy, cadastral market opening pressure and decreasing of cadastral survey work. It was confirmed that the role of cadastral organization has to be changed from the conducting cadastral survey organization to the spatial information provision organization. Eventually it should take a role to realize Spatially Enabled Society(SES) which is fundamental for national development and upgrading quality of life in the society. From the case study of international cadastral organization, cadastral organization should take core responsibility for the Nation Spatial Data Infrastructure(NSDI) and meeting the future costumers requirements through technical developments and organization's innovation efforts.

Continuously Operating Reference Stations (CORS) provides GPS measurements to support high accuracy CPS positioning. The CORS improves GPS positioning productivity by eliminating the requirement for GPS users to operate two receivers. Previously, this is achieved by providing data from CORS to users in post-mission mode. However, the efficiency of the CORS will be maximized by upgrading it in real-time operation using RTK-GPS surveying because users can obtain centimeter-level accuracy in real-time without operating their own reference stations. In this research, authors extracted the arbitrary point's coordinate which is using GPS CORS data, now served in RINEX FORMAT via Internet, with observation network of the existing triangulation and GPS CORS data. And then, RTK GPS was performed with this arbitrary point as reference station.

The Submillimeter Array (SMA) has provided forefront capabilities for high spatial and spectral resolution observations at submillimeter wavelengths from its excellent site on Mauna Kea, Hawaii since 2004. The SMA has continuously enhanced its capability. It is now equipped with two receivers in the 1.3 mm band (Rx230/Rx240) and two in the 0.85 mm band (Rx345/Rx400). The total bandwidth available is 8+8 GHz (per receiver) in the dual band or polarization mode. To maintain a leading role in the ALMA era, the SMA project is now upgrading its receivers, IF signal transport and correlator system. The new wideband SMA - the wSMA - will provide the instantaneous coverage of 56 GHz. In this presentation, I will introduce the latest status of the SMA, upgrade plan to the w-SMA, the possible science cases with the w-SMA, and the roles of the w-SMA in the ALMA era.

The method regarding obtaining various kinds of attribute data of spatial information, including that of digital map, is normally restricted to Geographic survey that deals with in-field surveys. Geographic surveying for drawing digital map, however, require much effort due to the fact that a surveyor has to characterize geographic features individually in the field. Not only does the Geographic survey cover large area, but also its need for manual drawing and surveying using Draft map makes it more expensive and time-consuming. Though some recent Geographic surveys take advantage of MMS(Mobile Mapping System) to collect computerized information, there are inevitable limits in creating digital map with such data. This research will analyze the problems in current Geographic surveys and suggest adequate methods and standards for Geographic surveys by researching the methods of domestic/international service organizations that deal with establishing spatial information. This study therefore will aim to enhance the efficiency of creating digital map and Geographic survey, which would ultimately maximize the applicability of pan-national digital map by improving reliability of digital map and upgrading the utilizability of Geographic survey data.

Purpose: General hospital in korea is getting large-scaled, specialized and upgraded. So, nursing unit of race track type has been advanced along with a spatial organization, building equipment and environmental approach. This study is to search the guidelines for renovation of nursing unit with race track type in the case of K university hospital in Daejeon. Methods: 9 cases of recently opened general hospital has been analyzed for spatial and environmental design solution. Questionnaires and interviews about user needs of nursing staff, patient and visitors, have been conducted for a nursing care system and facility of nursing units in K university hospital. Results: The user needs are represented as followings. Center core public zone in each floor plan and center core nursing station and supporting areas in nursing unit are good for an adjacency and separation of spatial organization. Toilet of group patient room is necessary to equip for easy, safe and infective aspects, and so toilet install will decrease the patient number and increase the nursing care service. Hall type of station front is good for visibility and observation. It is appropriate to renovate into south facing group patient room for privacy, enough space for nursing care facility and supporting area, enough width of door to move portable medical equipment, room for medical doctor and practical student, noise absorbing of day room. Implications: Upgrading the nursing care service and facility equipment is necessary to reflect the user needs and cooperate with hospital management.

Korea has established an advanced infrastructure for real-time precise positioning such as CORS, virtual reference station service and perform continuous upgrading. However, in order to utilize the national infrastructure, it is necessary to process the acquired spatial information and take many steps to derive the final product. In addition, this process is highly dependent on foreign software. In this study, GNSS field survey system was developed and evaluation of its usability was performed. Real-time GNSS field survey system was developed and the system improves user̓s convenience and usability. The system was able to conduct survey effectively and produce the results. In addition, we compare the existing software with the survey performance to show the availability of the real-time GNSS surveying system. The system developed through the research can perform all the functions from real-time survey to the production of the outputs. It can create economical added value of the foreign software as a whole and simplify the work required for post-survey performance.
