Zoning has long been criticized for its negative effects and has been taken for granted that zoning works as a hurdle to urban diversity. Responses in the US have emphasized more fine-grained zoning approaches that plan mixed use. This paper introduces and evaluates Seoul's zoning system as a possible alternative. While US zoning regulations have relied on distinguishing ever larger numbers of land use zoning categories, Seoul has opted to integrate new land uses into existing classifications, allowing for greater flexibility of use in each zone. Using municipal building records to evaluate land use in three mid-density residential districts, this paper demonstrates that Seoul's flexible zoning is capable of producing diverse mixed use neighborhoods. It then highlights the potential downside of this approach, showing that flexibility allows for the commercialization and sectoral gentrification of residential districts. It concludes by suggesting that a combination of flexible zones and more fine-grained plans would capture the advantages of both US and Korean planning.

High-rise mixed-use buildings are consisted of various facilities and circulations. Since various facilities and circulations are planned in a single site, circulation planning should be established after identifying the exact characteristics of facility and circulation. To this end, the components of the circulation planning in accordance with the formation of facility types are analyzed through the survey of experts based on Delphi Method. To identify the characteristics of the mixed-use buildings, by figuring out how the elements of circulation planning which are sought to be important by the planner has been reflected through analysis of the correlation between two sections. Researching on the circulation between two sections through Delphi Method and reflected circulation planning, it reaches the conclusion that the circulation of planning on the subject building is applied following the importance. In other words, the components of circulation planning which were sought to be important by the planner are reflected significantly when they planned the circulation planning on that mixed-use buildings. However, in case of design on the outdoor vehicle circulation, minimizing on the vehicle circulation at the 1st floor is not applied for the majority of the subject buildings different from the importance. In early 2000, high end residential buildings designed for mixed-use building have been specialized at vehicle-centered outdoor space and hotel style drop-off. Contrastively, sizable outdoor space at the 1st floor is designed to open to the residents and the local by minimizing the vehicle circulation in recent. Finally it shows that the way of circulation planning has been changed in accordance with time and trend.

In the manufacturing process of ready-mixed concrete, quantity management directly affects the workability and strength of concrete. Therefore, water quantity is the most important management factor for water quality control of ready-mixed concrete. It can be said that the number of unit water in the mix design, the water quantity due to the surface water contained in the aggregate used, and the water quantity taking into account the concentration of sludge contained in the recycling water when using the recycling water are factors that affect the quantity management of ready-mixed concrete. In this study, as a stable quality control method of ready-mixed concrete, a quantity management method by aggregate surface water and a sludge concentration management method according to the use of recycling water were proposed. Thus, we tried to suggest an efficient quantity management method for stabilizing the quality of ready-mixed concrete.
