In this study, the constitutional basis of public concept of land and concept of development gains are confirmed, and justification of the development charges system through the precedent of the Constitutional Court is investigated, and suggestions for improvement of fairness and reliability of development charges calculation are proposed. First, it is necessary to develop a system for estimating the development charges for securing transparency of the development charges system, preventing speculative development projects, and streamlining administrative efficiency. Second, it is necessary to prevent bad calculation by institutionalizing the responsibilities of experts to construct specification of the development cost calculation sheet submitted by taxpayers. Third, in order to precisely calculate the development cost, basic data should be specified in conditions for approval from the time of granting permission, or it should be minutely described in development charge treatment regulations.

The estuary in Nakdong River has changes by the construction of harbors, land reclamation and artificial waterway changes. These resultslead to changes of extinction and creation of deltaic barrier island. The deltaic barrier island changes in the Nakdong River estuary affect the function of the barrier islands and cause environmental changes. Therefore, it is important to monitor the changes in the area of the Nakdong estuary. In this study, long-term changes of the area and suspended sediment of deltaic barrier island in the Nakdong River estuary were analyzed using Landsat TM/ETM+ images. As a result, end point rate (EPR) values of shoreline in Jinwoodo and Sinjado are about 5m/yr and about 50 m/yr, respectively. The EPR values of north-south and east-west direction in Doyodeung are 20 m/yr and -20 ~ 10 m/yr. The suspended sediment concentration (SSC) has a maximum value of $25g/m^3$ in the vicinity of Jinwoodo and Sinjado, while it has a maximum concentration of $40g/m^3$ in the vicinity of Shinjido and Doyodeung. In other words, the area and the SSC change are small in Jinwoodo, and the area change and the SSC variation are large in Sinjado and Doyodeung. As a result of analysis of correlation between area change and SSC variation using all data, the Pearson coefficient value (r) is 0.36 and it is 0.32 in winter data. In other words, it is considered that the SSC variation affectsthe deltatic barrier island area change. However, verification using advanced altimetry data is necessary in the future. These studies can be used for coastal monitoring and environmental monitoring.
