This paper pays attention to the fact that not only Gangnam but also cities outside Seoul that attempt to follow the Gangnam model are deeply involved in Korean developmental urbanism. It examines discursive materials such as newspaper articles, newspaper advertisements and online debates as significant sources of information showing how certain districts are materially and discursively constructed by diverse actors in the national capital and in other cities. The result of in-depth interviews lasting up to two hours reveals local residents' imagined geographies. The article emphasizes that the so-called "Gangnam problem" should be understood as existing beyond the physical, symbolic and administrative boundaries of Gangnam, in cities that follow the Gangnam model. This study helps to provide an epistemological foundation for more equitable, sustainable and de-developmental urbanism.

There are many and various devices like sensors, displays, smart phone, etc. in smart environment. And contents can be provided by using these devices. Vast amounts of contents are provided to users, but in most environments, there are no regard for user or some simple elements like location and time are regarded. So there's a limit to provide meaningful contents to users. In this paper, I suggest the contents recommendation system that can recommend contents to users by reasoning context of users, devices and contents. The contents recommendation system suggested in this paper recommend the contents by calculating the user preferences using the situation reasoned with the contextual data acquired from various devices and the user profile received from the user directly. To organize this process, the method on how to model ontology with domain knowledge and how to design and develop the contents recommendation system are discussed in this paper. And an application of the contents recommendation system in Centum City, Busan is introduced. Then, the evaluation methods how the contents recommendation system is evaluated are explained. The evaluation result shows that the mean absolute error is 0.8730, which shows the excellent performance of the proposed contents recommendation system.
