Geoturism has been discussed from multiple perspectives in geomorphology and geology as well as tourism domain since 2000. As of May 2013, 172 academic papers and reports on Geoturism have been published in domestic journals. Themes of these researches can be categorized into 6 topics: resource development (i.e. natural resource development, cultural resource development, development of geopark), conservation and management, geoturist, local resident participation and public relations marketing, political approaches. Resource development among those topics has been treated the most: development and utilization of important geomorphological and geological landscape resources, storytelling development about cultual resources, contents development for geopark. On the whole, it is significant that geotourism is actively discussed in geography domain such as geomorphology rather than in geology domain. Up to date, those topics have also been treated only in certain academic areas. In the future researches, efforts for the balance among those topics and creating new themes from various research areas is necessary. Moreover, community networking among locals-municipalities-academia is also necessary to increase local participants.

As the number of aged-housing has been rapidly increased, many kinds of defects and problems such as degeneration of housing environment, structural performance, and equipment performance have been appeared. The reconstruction as the way to improve the aged-housing has been used mostly because the legal process of the reconstruction is relatively easy. On the other hand, it has caused problems such as the lack of natural aggregates, the environmental damages owing to construction wastes, the loss of national resources, and the lack of the housing for rent nearby the reconstruction area. This problems limit active tying into the reconstruction business at present in the industrial and political perspective. In this context, it is necessary to revitalize the remodeling rather than the reconstruction. In order to reach this objective, this research aims at identifying the user-oriented performance for the housing and deducing the core technology. It is expected that the result of this research can contribute to more revitalize the remodeling as tying researches in terms of design, structure, equipment, and construction.

The importance of demolition industry is becoming lager because of reusing and recycling of construction waste in current trend to pursue for sustainable development. As considering situation of the domestic housing construction and existing house, a scale of demolition industry is expecting to be increased continually. Therefore, for sustainable development is needed forecasting and managing rightly demolition waste to be producted at demolition phase. But, The development of model for estimating demolition waste is not sufficient in the country, also, the development of computer system for managing it rightly has not yet been created. In this study developed the estimating waste units for estimating demolition waste of an apartment and a house. A regression model for quantifying demolition waste easily is developed to do simulation again after making the estimating waste units through analyzing draws. This model is developed as a computer system for increasing application and then verified the reliability through field application. this regression model can quantify a sort of 22 demolition waste easily based on the size of the floor area and a number of units. This system is expected to quantify demolition waste easily which is producted during redevelopment and remodeling of existing house.

With the Government's policy of increasing the supply of residential houses in 1970s, the number of apartments have increased dramatically, and as the result, the number of old aged apartment are increasing too. Therefore remodeling is being executed to improve the residential environment. The rate of remodeling is increasing instead of rebuilding because rebuilding takes more resource and because of the realestate issue. There are many uncertainties in construction progress of remodeling such as communication between personnel, demolition and repair work. There are no standard for remodeling construction so such problems have been causing more problems. It has been found that BIM (Building Information Modeling) may be effective for resolving issues of standardization of remodeling construction. Therefore this study wishes to develop a standard process for remodeling work through BIM to estimate the possibility of its use at remodeling sites. Based on this, I wish to contribute to the issue of achieving construction efficiency pursued by BIM.

All the countries in the world is currently facing the full scale of energy-climate era currently, and making strong energy policy that will lead to green growth of the future energy resources by utilizing renewable energy as the basis of entering the advanced country becomes the goal of development that satisfies the demand for energy in 21st century. Recently, ocean energy attracted the attention along with the necessity of developing renewable energy. Ocean energy is the one of most prominent recyclable and clean resources that has not been developed yet. So, it is highly required to develop good tidal current energy conversion system in coastal area. The inflow angle that acts against tidal current turbine, seabed effect and the change of efficiency along the occurrence of cavitation were investigated through the wake flow characteristics in this study. Power coefficient degradation by seabed effect did not appear in the condition of this calculation. Efficiency degradation appeared from above $10^{\circ}$ regarding inflow angle and power coefficient was calculated as lower by 7 % at $45^{\circ}$. Torque and power coefficient increased as inflow velocity rose, but power coefficient degradation appeared from above 3m/s when the cavitation happened. So, it was recognized that the larger inflow angle and occurrence of cavitation become the reason for power degradation through the flow characteristics.
