As an apartment house as well as improving quality of life is becoming one of the brands, it is increasing the importance of the outer space with the facilities in the housing complex. In particular, the outdoor playground such as the community facilities that children and adults share as the activity areas for residents has received attention. However, actually children have not used many of Korean apartment housing playgrounds that were installed formally in the scrap area according to the housing plan by residential construction standards. it is considered necessary to improve the quality of the playground in housing complex and reform it in order to make the eco-friendly play space in which children can play safely and h healthily. As an alternative, we analyzed the eco-friendly properties of the playgrounds installed in the eco-friendly housing complex in Germany and derived the main planning elements of eco-friendly playground. In the observational survey of the 10 playgrounds in 9 housing complexes in 5 regions in Germany, we evaluated the environment-friendliness of these playgrounds in the 8 fields(location and placement, ecological environment, play space, play equipment and facilities, additional facilities, materials and resources, energy saving, environmental load reduction) according to the levels(suitable, partial reflection, unsuitable, non-reflection) of reflection of eco-friendly planning factors. The following is the summary of the results about the reflection of eco-friendly planning factors. In terms of "suitable": location and placement(88.8%), play equipment and facilities(73.5%), additional facilities(60.6%), environmental load reduction(54%), and ecological environment(50%) were higher than others. In terms of "unsuitable": there was nothing. In terms of "non-reflection": energy saving(95%), additional facilities(32.2%), and materials and resources(30.9%) were in order. Therefore, on the basis of these results, this study proposed the planning indicators to be considered first and the planning factors that should be complemented and improved in the construction of apartment housing playground in future.

The purpose of this research is to examine generational distinctions of housing investment and household wealth for two different age cohorts - 'baby-boomers' and 'eco-boomers'. In so doing, national survey data of two different periods were analyzed and the primary results are summarized as follows; aggregate assets of both generations have risen, and the rising household debt for baby-boomers was related to loans for living expenses while eco-boomer's debt was ascribed to home-buying loans. In the midst of economic slowdown, the age cohorts had conservative asset allocation in preference for risk-averting investment like savings. The main purpose of saving and investment was distinctive across the groups? retirement for baby-boomers and home purchase for eco-boomers. Both groups prioritized reduction of household liabilities and also were cautious on investing in real estate. Still home-buying was considered to be an important driver for asset accumulation. While baby-boomers were unwilling to dispose any form of owned real estate, eco-boomers found it challenging to take on a long-term investment like home-buying, especially in economic uncertainties. Rather the young generation would diversify asset allocation with better-returning investment commodities like stocks, bonds and derivatives.

For the purpose of evaluating the eco-efficiency(EE) on surplus heat generated from industrial process, techniques of life cycle assessment are adopted in this study. Because it can be indicated both environmental impacts and economic benefits, EE is well known as a useful tool for symbiosis network on the sustainable development of new projects and businesses. To evaluate environmental impacts, the categories were divided into two areas of resource depletion and global warming potential. It can be seen that environmental impact increased a little but much higher economic benefit on the company, environmental performance and economic value were improved on the apartment by the district heating, respectively. In result, eco-industrial park(EIP) project on surplus heat should be found sustainable new business because the EE was in the area of fully positively eco-efficiency and, moreover resource depletion was taken place than the reduction of greenhouse gas.

Recently, habitat fragmentation and shrinkage has occurred because of increased road construction. As a measures mitigating the adverse effect such as eco-island by road construction, Korea has been installed eco-corridors since 1995. Using the Analytic Hierarchy Process (AHP), this study analyzed the importance of assessment items and the criteria to determine which areas require eco-corridors the most. First, related literature reviews, preliminary surveys, and expert interviews were carried out to develop assessment items and criteria for constructing the hierarchy. Second, experts were surveyed in order to determine the relative importance of the assessment items by applying the AHP. As a result, it found that the restoration of the ecological network was the most important assessment item, followed by wild animal resources in the Level 3. In the Level 4, the eighteen items were ranked in the order of their relative weight and it was found that the 'Baekdudaegan Mountain Range (0.189)' was the highest ranked item. Therefore, this approach can be applied to effective selection of the priority areas in planning eco-corridors in the national scale.

The objectives of this study were to analysis the nutrient cycles of agricultural by-products. The region, in which agricultural by-products are circulated for use within the agroecosystem for minimizing the input of artificial nutrients as well as generation of wastes, and where ecologically industrial diversity is formed, was defined as the regional agriculture focused on eco-industrial approach. Plan in stages for promoting ahead with the regional agriculture focused on eco-industrial approach is as follows: First of all, "The Consultation Body for Circulating & Using By-products" should be formed. Secondly, usage of agricultural by-products is identified to select the facilities of recycling and its location including the type and amount. Thirdly, the facilities for recycling of resources and infrastructure are installed. Finally, the facilities for recycling and resource circulation system within the area are efficiently managed.

The planting plan for the establishment of Eco-bridge were suggested to restore the ecosystem where has been ecologically isolated by rood construction in Chimgogae of Odaesan National Park. Eco-bridge contributes as a corridors to the faunal movement. To survey the vegetation, 16 plots within 6 sites were selected and 10 by 10 meters in size set up. In the results of Chingogae's vegetation analysis, succession trends was from Quercus mongolica to Carpinus laxiflora, Carpinus cordata, Fraxinus rhynchophylla, Tilia amurensis and so on. It turned out that the nearer sites had high similariyt and vegetation continuity obviously in the similarity index analysis. In the analysis of the number of species and individuals, final step of planting plan needs about 15 species and 10~12 trees, 17~18 subtrees and 100 shrubs in size 100m$^{2}$. Planting species was selected from adjacent sites. The plant species suited for the eco-bridge establishment in this area can be suggested such as Carpinus cordata, Cornus controversa, Q. mongolica etc. and 12 subtree and shrub such as Syringa reticulata var. mandshurica, Sambucus williacsii var. coreaca, Acer pseudosieboldianum and so on.

Theses days, there are 3 prerequisites for dam building in Korea: First one is how to build the dam safe and stable from the technical points of view. Second one is how to design and construct the dam environmentally sound with the minimum change of the surrounding area of the dam site. Third one is how to activate the local economy of the surrounding area of the dam site in order to make the dam construction sustainable from the social and economical points of view. As far as technical aspects far dam building, there are hardly any problems in dam design and construction in our country. However, there are a little difficulty according to the location of the dam site. In order to fulfill the second option it is believed that a lot of effort should be made to accomplish the second task not only because that fairly large area shall be inundated with water after impounding but also because that ecological environments shall be changed due to change of water environment. Therefore, thoughtful investigation and assessment of the environmental features of the local regions have to be preceded before starting of the dam building. In order to overcome these difficulties Hantan river dam has been declared as an Eco-dam with 3 strategies and 9 activities plan at the design stage after sufficient consideration of the local identities of these region and coupled national plans for surrounding areas. Finally, Eco-tourism with the several coupled network-wise touristic courses, namely PERTH model, has been proposed after thorough analysis of the local identities by the Jahari window to make local economy being activated. Detailed descriptions for 3 strategies and 9 activities plan for declaration of Eco-dam and proposal of Eco-tourism with the network-wise touristic courses will be mentioned in the main content.

PEMFC stack power output is needed to be around 100 kW to meet the requirements of automotive application and scaling-up the active area of the stack cells will allow a higher power. In the case of scaling-up the active area of cells, it is difficult to obtain uniform in-plane internal conditions such as temperature, relative humidity and stoichiometry of the feed gas. These ununiformity with the location in the cell would affect both the performance and durability of the stack, so it is important to understand phenomena in the cell for improving them. In this study, the current density, electrochemical resistance and performance distribution measurement was performed to understand the ununiformity in a single cell using in-situ method; (1) Current Density Distribution (CDD) Device and (2) Segmented Cell Fixture. The influence of location of feed gas on the performance of a single cell was experimentally measured and discussed by using a segmented single cell which was composed of 8 compartments. The correlation between the location and performance in a single cell was discussed by these two tools and it was extended between the local characterization and the durability in a MEA by comparing the used cell with a fresh one. It was also studied in terms of electrochemistry by Electrochemical Impedance Spectroscopy.

Innovation plays a large role in green growth. While it is a widely accepted view that, without innovation, it would be very difficult and costly to address major environmental issues, innovation itself tends to be constrained by limited access to eco-financing and is inherently risky, often requiring a long-term horizon. Although global consensus is more or less established as to the urgency and necessity of accelerating green innovation, the quality and quantity of financing in this area is largely insufficient, with increasing funding gaps in many countries. A new financial mechanism is urgently needed in order to re-orient financial flow and enable innovators to overcome the valleys of death that occur throughout the innovation cycle. A number of different modalities exist in financing the commercialisation of eco-innovation. Existing mechanisms have not been as successful as expected, revealing critical limits to furthering certain types of projects that are essential for economic and environmental progress. Experts' estimations have shown that the funding gap will widen in the coming years as demand for clean energy and green infrastructure rises, and as green technologies and innovation develop faster than the market for it can develop. Against this backdrop, the main purpose of this research is threefold: to identify issues and problems regarding current means of funding for eco-innovation and green projects; to provide insight into securing longterm green financing by looking at European cases; and ultimately to suggest policy implications for designing and implementing eco-specific financial instruments, focusing on governments' roles in sustainable financing for eco-innovation. This study analyses different models of financing mechanisms, a mix of public and private funds, in view of suggesting conditions for the sustainable financing of green projects, especially for large-scale high-risk projects. Based on the findings from the analyses of mechanisms and the shortcomings of the existing funding modalities, this study ultimately suggests policy implications for effectively supporting the commercialisation of eco-innovation.
