The direct synthesis of metal-organic frameworks (MOFs) with acidic and basic active sites is challenging due to the introduction of functional groups by post-functionalization method often jeopardize the framework integrity. Herein, we report the direct synthesis of acid-base bifunctional MOFs with tuning acid-base strength. Employing modulated hydrothermal (MHT) approach, microporous MOFs named $UiO-66-NH_2$ was prepared. Through the ring-opening reaction of 1,3-propanesultone with amino group, $UiO-66-NH_2-SO_3H-type$ catalysts can be obtained. The synthesized catalysts were well characterized and their catalytic performances were evaluated in one-pot glucose to 5-HMF conversion. Results revealed the acid-base bi-functional catalyst possessed high activity and excellent stability. This work provides a general and economically viable approach for the large-scale synthesis of acid-base bi-functional MOFs for their potential use in catalysis field.

Current international negotiation and cooperation for sustainable development are focused on three main themes. The first theme is implementation of Sustainable Development Goals (SDGs). The second theme is development of measures for climate change. The third theme is sustainable management of biodiversity and ecosystem services. In South Korea, responses of government policies and academic studies have been predominantly to one of these three themes. There have not been many integrated efforts to develop countermeasures considering all three international themes. In addition, while "green growth" policies have been setting national agendas for Korea's sustainable development, they must be scrutinized such as why they have not dealt with some parts of these three themes and whether they have ignored one of these themes due to lack of integrated responses. This study finds critical issues in South Korea on how to harmoniously respond to the three themes of international efforts and improve green growth policies. First, to achieve SDGs, the domestic statistical system must be reorganized to track the achievement of "inclusiveness" and "green growth". Second, the climate change response policy should seek inclusion between countries and between social groups. Third, in the field of biodiversity and ecosystem services, it is necessary to establish Korea's identity in global geopolitics and enhance its own traditional ecological knowledge. Fourth, it is necessary to consider how to solve discrepancy between climate change response policies and biodiversity-ecosystem service management policies. Finally, proactive improvement of laws and institutions must occur to promote inclusive green growth.

Many countries have carried out various policies about sustainable building to protect the earth against the global warming and environmental pollution. Korea government has also executed the Green Building Certification System. In order to keep the performances of certificated buildings sustainable, the effective building maintenance is quite necessary. Meanwhile, the foreign green building certification systems have considered the building maintenance as one of the most important items to keep the building performance effective. However, Green Building Certification Criteria(GBCC) of Korea has not had the sufficient criteria for the maintenance of green building. Therefore, The purpose of this study is to find direction for the improvement of management categories of Korea Green Building Certification Criteria. For this aim, GBCC was compared with the foreign certification systems such as LEED, BREEAM and CASBEE.

The purpose of this study is to suggest a actual conditions and expert's role on the green tourism in rural community. There are four types of green tourism in rural villages. It is an alternative tourism that has naturalism and sustainability, not mass tourism. I can find it is a one of the new rural development method in a point of view of rural people's income. Green tourism requires a participation of village peoples. So, management hang on not government office, but village people themselves. By surveying green tourism villages in the case of this study, I propose a few results as follow; firstly, green tourism of Korea will give an innovation to stagnant rural society. Secondly, rural people themselves must participate directly in development and guidance, when every programs are advanced. Thirdly, through this project of green tourism, we expect that urban and rural symbiosisically have a network.

The purpose of this study was to describe the policies and outlooks of the green jobs including the forest area. The Methodology of the study was mainly on literature review and second data used and analyzed to get the result. The findings of the study was the manpower of Green Jobs was 2.5% in 2009, it should be expected to 2.9 percent in 2016, and overall of the green jobs and forest area of the outlooks should be increased from 46 percent to 56 percent in each sector of green and forest area. The climate changes and environmental pollutions would push the conditions of new green jobs in forest area as well as waste-based industry. The suggestions were made based on the study of which one is policy-making should be prepared for creating Green Jobs and the forest area.

The need for this study must be considerable, as being activate of green roofs research that the organization and construction obtain access to more development technologies. Nevertheless, the green roofs system has begun to apply since 1980's, the green roofs technology was restricted to develop without verification of technologies such as a load or water leakage. There is a limit as urethane waterproofing to almost domestic waterproofing materials and methods of construction for general green roofs. The introduction of materials and methods of construction which are appropriated to property of green roofs could be a decisive factor in a long-range durability and economical maintenance cost, moreover. it support to variety construction system and organization. This present paper describes a necessity of waterproofing and root barrier system is one of the sub-organization based on green roofs construction. which have enormously large impact on the durability.

Green and plants, as it symbol the life and depute the nature, always give human an easy comfort psychologically. The paper is a brief analysis to the idea frame of urban construction and reform of Kunming through our practice about ten years. On which three main principles should be carefully considered. One is that the green-space composed of plant system is of the important infrastructure of a modern city as it can not be instead of by any other factor in the ecological system of the city. The other is that in the course of planning and construction the local feature as well as its culture tradition in history should be pied more attention. In order to create a distinguish character of itself the third may be more important that to coordinate each key elements of it such as green, water, light, building, road, etc., to get a harmonious sphere of human and nature. A modern city should be a green city in which nature and man co-exist harmoniously.

Green Infrastructure has been considered as one of strategies for flood mitigation in cities. Although, the diverse benefits of green infrastructure implementation are studies, there is a lack of research on the relationship between spatial composition and configuration of green infrastructure and urban flood mitigation. To address this gap, this study 1) utilized high-resolution satellite imagery to analyze spatial composition and configuration of green infrastructure in highly developed seven cities in South Korea, and 2) conducted an empirical analysis to find the relationship between economic losses from flooding and spatial patterns of green infrastructure and development patterns. The results of this research will be helpful for urban planners to prepare green infrastructure implementation guidelines for effective urban flood mitigation.
