Soil ecology has important roles in global ecosystems. However, soil ecological quality information is being ignored when assessing ecological impact of construction actions. And methods for classifying and assessing soil ecological quality have been very little established in comparison to those for animal and plant ecosystems. In this study, it was examined whether soil ecological quality information has influence on determining an eco-friendly route for a road construction project. For this, sensitivity analysis was systematically performed by varying the relative significance (weights) of soil ecological quality information among natural environmental and ecological factors. When the weight of soil ecological quality was greater than just 14%, the soil ecological quality information significantly influenced the determination of the eco-friendly routes for a specific road construction project. This demonstrates that soil ecological quality information has to be considered for more reliable environmental impact assessment, and also supports the validity of use of soil ecological quality information and its mapping technique in planning and siting of eco-friendly construction projects.

In the previous test, the verification of the standard floor impact source was carried out comparing the physical characteristics with living impact sources. The result was appeared the validation of the standard impact source was very low because of differences of physical characteristics. This study aims to evaluate annoyance and loudness of standard impact source which is used for the measurement of floor impact sound, and to compare the annoyance and loudness of living impact sources which are produced in real life. The impact sources considered are tapping machine, tire and impact ball as standard sources, and nine real sources which were chosen from the existing researches. The result showed differences of annoyance and loudness between standard impact sources and living impact sources, which means the standard impact sources may rate the performance of floor system inappropriately. In the future, the rating method should be examined how the standard impact sources are similar with real sources in the point of rating the performance of floor system.

The purpose of this study was to determine domestic and foreign ecological asset research trends. We aimed to understand ecological assets research directions and trends by comprehensively analyzing 12 keywords, including those similar to keywords for comparable assets, to identify related fields and regions. Extensive analysis of domestic and foreign studies was conducted through keyword network analysis of textural information. This approach is helpful for understanding the flow of information and identifying research directions. Foreign studies based on sustainability were connected with 'Economic assessment', 'Management' and 'Policy' areas. It was difficult to determine domestic research trends because there are fewer domestic studies than foreign. There were studies that sought to identify economic value of developing regions. This research can be used to guide the research direction for future ecosystem asset analysis in Korea.

The spatial range of EIA is mainly related to landscape ecological factors such as topography, geology, animals, and plants. Problems were detected involved land, soil, noise, oscillation, the atmosphere, animals, and plants in the natural-environment. First of all, the current EIA lacks explicit spatial ranges and sections in terms of scientific exactitude and objectivity for assessment. Secondly, there are overlapping influence-area problems resulting in cumulative impacts of unit developments that accumulate. Finally, some developments have no regard for ecological and conservational value in relation to determining which effect ecological stability, and which should be regarded as Regional Ecological Resources. Therefore, this study suggests that EIA should be improved in the following manner. First, the standard classification of landscape unit for analysis should be established 10 regulate each spatial range on a wide-landscape scale. Secondly, the impacts resulting from the interaction of overlapping influence-area developments between individual development should be assessed. Third, Minimization of the of the environmental effects is needed by applying the cumulative effects to the influence-area where developments occur in the same time or in a sequence. Fourth, individual characteristics of landscape elements such as roads, rivers, and green networks need to be considered separately in the analysis. Finally, regional ecological habitats should be included in the analysis in order to achieve stable ecosystems.

This study performed the impact of ecological waterway on fish community in a reach of the Dal River, Korea. Fish monitoring revealed that 9 fish species are dominant, namely Zacco platypus, Coreoleuciscus splendidus, Zacco koreanus, Pungtungia herzi, Acheilognathus yamatsutae, Rhinogobius brunneus, Tanakia signifer, Gobiobotia macrocephala, and Pseudopungtungia tenuicorpus, and account for 95% of the total fish community. The River2D model was used for the computation of the flow and the HSI model for the habitat simulation. The restoration of the waterway performed through the small dam removal, the formation of the pool-riffle structure, and the change of the bed elevation and width. Simulation results indicated that the restoration of the ecological waterway effects significantly increased by about 16% for the WUA (Weighted Usable Area) of the total fish community in optimal ecological flow conditions ($Q=7.0m^3/s$). The restoration of the ecological waterway is more advantageous to fish community.

The purpose of this study was to investigate university freshmen' stress coping strategy and psychological wellbeing to appling ecological family life welfare model. Based on Bronfenbrenner's ecological perspective, “ecological family welfare model”, which includes person(individual attributes), context(family backgrounds), process(mechanism of development), and time (the specific period), was suggested as a new research paradigm for family welfare life research. The questionnaire study was done for 171 freshmen of an university in Pusan. The results show the suggested research model was significant and effective to explain the mechanism of stress coping strategy and psychological wellbeing. Individual attributes(i. e., attachment style) and family context have an impact on family cohesion and adaptability which in turn affect stress coping strategies which then affect individual psychological wellbeing.

The objective of this research was to determine the relative impact of demographic variables and ecological factors on the parenting stress of dual earner families. Subjects were 318 fathers and 405 mothers who completed the questionnaire on parenting stress and ecological factors. Results showed that mothers perceived high parenting stress compared with fathers. Degree of satisfaction with child care was a significant correlate of parenting stress. Demographic and ecological factors were also important in understanding the variation in parenting stress of dual earner families. These findings imply that the formal child care systems and parent education programs are needed for working parents.

The environmental conservation-targeted zoning in urban planning process has been functioned as securing a ecological core in urban green spaces management. Hence, the designation of conservation zones in land use planning is considered as a key task to achieve the sustainability of urban planning. The recently introduced pre-environmental review system for the proposed urban plan, by which the conservative measures for urban ecosystem and landscape are suggested in aspect of environmental impact mitigation, has played an active role in enhancing the environmental performance degraded by wide range of development pressure. This study is aimed at drawing out of objective criteria for designation of environmental conservation zones, which can be applied to urban planning establishment and also to environmental assessment process. To achieve this goal, the study adopted the following methods; pre-study review, analysis of existing official opinion statements released by the Ministry of Environment, contents analysis of related laws, and experts' panel discussions on the finally arranged criteria. The results of this research can be summarized as follows: First, the total criteria of 48 are drown out with categorizing into environment-ecological and socio-cultural sectosr. Second, the environment-ecological part is composed of 33 criteria such as vegetation, animal, geomorphology, watershed, environmental land suitability, and etc. Here, the Degree of Ecological Function, Degree of Environmental Land Suitability, and Vegetation Map are mainly utilized. Third, the 15 socio-cultural criteria relating to the history, social ecology and landscape have such components as forest around relics, Seo-won(school), castle, tomb, landmark, skyline, natural landscape, and etc. Forth, these individual criteria can be applied to designation of each conservation zones among total of 11 conservation areas(or districts).

In this study, the functional priority of wetlands was determined through analysis of previous research. To determine relative importance, three processes were performed. First, quantitative values from the case studies were normalized. Second, non-quantitative values were prioritized based on standard criteria. Third, equal weight was applied as long as there was no special consideration regarding a particular value's disproportionate priority in the research. Finally, results were grouped into large, medium, and small classes.In this study, the functions of the medium class were found to be the most significant, in the following order of priority: water supply and ground water recharge; culture and recreation; biodiversity; product; water quality control; flood control; erosion control; moderation of climate change; and provision of biochemical matter. To verify these results, we compared our findings with those of an assessment that used the Rapid Assessment Method (RAM) on the same type of study area. Whereas this comparison indicated some correlations by the culture, water storage, and genetic sustainability functions, it suggested a lack of such relationship by the water purification and flood prevention functions.

Ecological villages should be designed not only for simply reducing environmental impact such as energy saving and alternative energy use, resource conservation and circulation, harmony with surrounding environment and nature, but also for encouraging social contact and community activities with the residents, especially the aged people. The aim of this paper is to find the ecological and social design elements for the ecological village planning derived through case studies. The case studies are selected from the environmental Co-housings in Western America, surveyed in the years of 2008 and 2009. The results are as follows; 1. The ecological design elements, although there are some differences in size and type, were found to be basically applied in every ecological villages. 2. The community activities are actively conducted with the participation of the residents based on a variety of programs. The two main purposes of the community activities are strengthening the residents' familiarity with each other and the volunteer services to the local community where they belong.
