The Spatial Image contents of Geomorphology 3-D environment is focused by the requirement and importance in the fields such as, national land development plan, telecommunication facility management, railway construction, general construction engineering, Ubiquitous city development, safety and disaster prevention engineering. The currently used DEM system using contour lines, which embodies geographic information based on the 2-D digital maps and facility information has limitation in implementation in reproducing the 3-D spatial city. Moreover, this method often neglects the altitude of the rail way infrastructure which has narrow width and long length. This As the results, We confirmed the solutions of varieties application for railway facilities management using 3-D spatial image contents and database design. Also, I suggested that U-city using railway modeling about matching methods of high density elevation value using 3-D aerial photo with laser data are best approach for detail stereo modeling and simulation.

Parodos, the side entrances to orchestra (acting space), was one of the intrinsic elements for the ancient Greek theatre structure. It is worth noting that parodos was the sole structural component that remained the original form while all the other elements such as orchestra, skene, and theatron experienced drastic or gradual changes in form throughout the passage of time. On the reason for parodo's maintenance of the original form, this study suggests a possibility that parodos could be the most intrinsic among the elements for Greek theatre buildings. For evidence, this paper indicates the historical fact that the procession tradition was the key event in the national or civic festival known as City Dionysia, and that the single-direction passageway, as seen in the Panathenaic Way passing through the City Athens, could be the easiest and most efficient way to realize the cause for the procession tradition that is the citizens' participation and subsequent unification. This study suggests another possibility that the single-direction passageway in the procession could be the archetype of parodos. For evidence, this study finds that this type of passageway was ubiquitous around the City Athens especially in the Agora, the most popular place in the city and the gateway to the processional event for Dionysian Cult as well as the space for the earliest Greek theatricality and, therefore, was familiar to the citizens. From the discussion, this paper argues that the Greek theatre should be the miniature of the Agora in terms of form (single-direction passageway) and function (civic participation and unification), and that parodos was the theatrical version of the processional passageway in the Dionysian Cult. In conclusion, this paper argues that parodos played a double role. It satisfied the theatrical necessity by functioning as the passageway to dramatic action (entrance and exit of actor/chorus) and as the literal door for the entrance of the audience members. At the same time, it satisfied the social cause, that is civic participation and subsequent unification, by functioning as the processional passage to relay the theatre space to civic events for the national religious cult.

There are rapidly increasing in the number of SNS users according to quick supply of smart phones and expansion of wireless internet services, but there is no much researches on hospital promotion using SNS. In this paper, we proposed methods for development of effective hospital promotion by investigating current status of homepages, mobile web contents and SNS operated in 21 dermatology hospitals located at Seoul city and by analyzing contents according to functions as hospital promotion media. In the investigation results, all of three contents such as homepage, mobile web content and SNS are opened in 76.1% of hospitals and external companies occupied the main management body of the three contents at the largest portion(56.2%). There are hospital information, clinic, reservation in all hospitals' homepages and followed by broadcasting(90.5%), medical treatment(85.7%), consultation information(80.9%), member information in 'mypage'(42.9%), staff information(14.3%). In the analysis results, there is need to enlarge departments or staffs taking full charge of in order to manage the three contents professionally and also there is need to prepare and conduct hospital promotion methods using prevalent SNS.

With the rapid development of both ubiquitous computing and the mobile internet, big data technology is gradually penetrating into various applications, such as smart traffic, smart city, and smart medical. In particular, smart medical, which is one core part of a smart city, is changing the medical structure. Specifically, it is improving treatment planning for various diseases. Since multiple treatment plans generated from smart medical have their own unique treatment costs, pollution effects, side-effects for patients, and so on, determining a sustainable strategy for treatment planning is becoming very critical in smart medical. From the sustainable point of view, this paper first presents a three-dimensional evaluation model for representing the raw medical data and then proposes a sustainable strategy for treatment planning based on the representation model. Finally, a case study on treatment planning for the group of "computer autism" patients is then presented for demonstrating the feasibility and usability of the proposed strategy.

Recently, we designed an interactive virtual space for the multi-purpose hall in Songdo Future City, located in Incheon, Korea. The goal of the design is to make a virtual space that is flexible and can be adjusted thanks to its unfixed seats in order to accommodate different and unspecified audience sizes. Virtual images are interactively adjusted according to the distance, position and size of audiences, information about which is detected by 9 photo sensors. To increase the sense of immersion, intensity and reality, we utilized the technology of scent display that can create appropriate scents to match the images on the screen. The intensity and persistence of scents were determined by the size, distance and position of audiences. The virtual image contains background images and reactive images. The background images repeatedly project images of spring, summer, autumn and winter. The reactive images consist of small portraits or pictures or icons that define or characterize the season types, and these are added to the background image according to the distance, position and size of the audiences.
