Through analyzing the specific physicochemical alterations in depth-based soil at reclaimed dredging area, the baseline data were provided for developing the reclaimed dredging area as natural landscape planting sites and ecological-landscape sites based on the soil improvement technology. There was no physical disturbance for 15 to 20 years in Gwangyang Bay reclaimed dredging area after reclamation. Physicochemical examinations of the soil were performed based on the vertical depth. Results of physicochemical analysis such as pH, electric conductivity, total salt contents, silt, clay contents, available phosphorus, calcium, magnesium, sodium, chlorine, and sodium-adsorption ratio showed increasing patterns with the depth while total organic contents, total nitrogen, and sand showed decreasing patterns. Potassium as an exchangeable cation, showed similar distribution patterns between the shallow and deep soil. This result strongly implied that long-term exposure to natural rainfall in reclaimed dredging area altered soil characteristics related to salinity. This research demonstrated that there were no remarkable differences in physicochemical characteristics at soil depth and groundwater table height, suggesting a baseline data for developing reclaimed dredging area. Additional investigation is required for different reclaimed dredging areas. Also, additional monitoring and examination are need on plant communities and time variable alteration in the soil to test the feasibility of reclaimed dredging areas as natural landscape planting sites and ecological-landscape sites.

The purpose of this research is first, to define what measurement items in terms of subjective consideration and preference can be used to assess the landscape values of agriculture and fisheries heritage, and second, to understand the perceptive patterns particularly how landscape experts weigh up the importance of the each measurement item. In order to extract the measurement items, extensive literature review was performed including research documents as well as domestic and international policy reports. A survey targeting the experts was conducted to ask their opinions on the importance of the selected items. For the analysis, SPSS 20.0 for Windows was used to carry out reliability analysis, descriptive statistics such as arithmetic mean and frequency distribution, factor analysis, and multiple linear regression modeling. The results are: the importance value of the landscape values in agriculture and fisheries heritage was 4.1494; the ratio value that the experts perceived the importance was 87.2%; and the average of the importance value of the analyzed items was 3.71. All the items have more than 3.00. Ten factor groups were summarized and defined whose total explanation power was 67.86%. The factor groups were named as lyricism, authenticity, environmentally-friendliness, durability, recognizability, regionality, visibility, value of sightseeing, social image, and universality. The factors influencing the landscape values are, in order of importance, recognizability, authenticity, visibility, universality, durability, and nativeness. According to the analysis, however, environmentally-friendliness, regionality, value of sightseeing, and social image were not as important.

When situated in green landscapes, water bodies play a crucial role in positively influencing mood and mental health, yet research on the cognitive mechanisms underlying these therapeutic effects is lacking. This study is intended to examine differences in brain function among adult males exposed to forest landscapes with or without water bodies. The wooded landscapes included views of a waterfall, a valley, and a forest without water. The control group was exposed to a local urban landscape. Twelve adult males participated in a field experiment in which prefrontal cortex (PFC) activity was measured using near-infrared spectroscopy (NIRS). In the experiment, participants engaged in low-intensity walking in three forested areas with similar vegetation and climatic conditions. Participants showed significant differences in left PFC activity depending on whether they were in the three forested landscapes or in the control landscape (P < 0.01). An analysis of variance (ANOVA) confirmed that significantly lower left PFC activity was recorded in the wooded landscape containing a water view . Notably, the lowest PFC values recorded in the landscape with a waterfall view suggest that landscapes with dynamic water flow may be associated with greater therapeutic benefits in terms of PFC activity than static landscapes. Our results underscore that water is a critical aspect of a landscape due to its therapeutic benefits and should be incorporated in the planning and design of green spaces for health promotion.

This study emphasizes users' participation, a living-transforming visuality, as users have appeared to be a central element of landscape design but ignored before. Also this study tries to propose meaning of extended visuality in contemporary landscape design on the basis of visual criticism on simple perception-and contemplations convention-based landscape design. For these purposes, this study reviews characteristics of visual changes appeared in modern reductionist paintings. In other words, arts can be interpreted in polysemous ways through bodies' experience. Deconstructive concepts derived from the theoretical reviews can be categorized into three including the participation of the users' bodies from a contemplative point of view, textuality and intertextuality, and experiences from works. Those concepts were used to criticize the previous discourse on landscape designs and to analyze various issues in the theories, themes and techniques in contemporary landscape design. The significance of the expanded visuality in contemporary landscape design is that it brings the users' voluntary participation. This structure can serve as a tool to obtain the users' perceptive effects. At the same time, it can be regarded as a process of establishing the relationships between the users and the works. Thus emphasis is placed not only on the influences of the effects structure of the works themselves, but also on the many different dimensions related to the users' bodies. It implies that the meaning of design is not determined by the designer but a product resulted from the voluntary relationships between users and works. These findings lead to ambiguous distinctions between arts everyday life, and eventually to the end of the concepts of formative dichotomous aesthetics and their effectiveness. Finding of this study call for not only redefining the space where landscape design is created and communicated, but also reconsidering the concepts of landscape design and its ontological meanings.

Major and reckless development which have been continued during the last half century, have caused decrease and damage of urban green spaces in the point of qualitative and quantitative view. Particularly, it brought about reduction to urban neighborhood park which has taken the main role for landscape ecological value. Recently, neighborhood park planning based on the landscape ecological results has been increasing gradually. Most of all, diverse attempts such as the application of shape character analysis and the step of landscape ecological planning in urban park planning have been proposed. Today, we recognize the importance of comprehensive approach in urban green planning and neighborhood park planning, but landscape ecological approach which is analyzing character and making proposal with isolation, connection and circulation is still insufficient. Most of neighborhood parks in Korea are surrounded by buildings and isolated from adjacent green spaces. Besides, these parks have landscape ecological problems such as reduction of size, isolation from adjacent green spaces, decline of nature, and excessive pavement which we ignored during urban development process. We have sympathy for understanding landscape ecological characters and considering improvement proposals for neighborhood parks Therefore, the purpose of this study was to 1) select five neighborhood parks in Daegu, 2) analyze landscape ecological characters with isolation, connection and circulation, and 3) compare data. It is certain that these results should be the main data for the arrangement of improvement proposals which landscape ecological characters were appled to.

Although we have seen recently increasing number of eco-villages, any eco-village is not registered in Global Eco-village Network. It is important to review the definition of eco-villages and to provide useful basic information for future eco-villages. The main research aim is to analyze landscape characteristics of community garden and common spaces and to identify ecological symbolism of landscape created by residents in eco-villages. Seven eco-villages in Germany, Denmark and UK were selected and the following aspects were investigated through field survey; the settlement background, social and economical aspect, architectural specifications, recycled energy, and landscape characteristics of external spaces in eco-villages. The result indicated that the landscape of eco-village did intend neither to return to primitive society nor to control nature by technology. It intended to coexistence with nature. Primitive nature is symbolically restored and people who have it in mind strongly intend to grow together this common sense. Landscape creation has important role in creating common relationship between human living and nature. When we regard it conceptually as the eco-symbolism in landscape design of community garden, it presented the meaningful relationship with landscape and human life. It is not expression of landscape materiality and designed form but sense of place and landscape image. Landscape design would be expected to reveal the life stage and cycle from designed physical form and materiality through as time goes by when it is part of environmental circulation process by means of human living as meaningful relationship.

The purposes of this study are carrying out the case study for the urban park planning in point of landscape ecology, analyzing and evaluating the indicator character of the landscape ecological view on the basis of the case study, and proposing the urban park planning in point of landscape ecology. The results of this study are as follows. As a result of the isolation analysis with school green space, Kyukchaebosang Park turned out to be 607m, Chimsan Park to be the highest 647.14m, Ehyeun Park to be the lowest 592m. In the case of connection analysis with all nodes, Kyukchaebosang Park had the lowest score 0.27 and Chimsan Park had the highest score 1. As a result of the circulation analysis with elementary schools, Kyukchaebosang Park and Ehyeun Park got 1 within 500m permissible range, and Chimsan Park got over 1, Ehyeun Park got 0.67, and Kyukchaebosang Park got 0.14 respectively within 700m permissible range. According to these analysis results, special regions which has problems such as high isolation and low connection and circulation in point of landscape ecology can be selected. Also by changing them to valuable green spaces, urban park planning can be improved. In this study, the basic data of landscape ecology can be obtained by the character analysis of landscape ecology. This study has a significant meaning of possibility in planning of the urban park which reflects the character of landscape ecology. This research was only performed in Chimsan Park, so additional researches for various cases will be needed.

Restoration ecology is undergoing rapid growth as academic field over the last 15 years. The specification of goals for restoration projects is frequently described as the most important component of a project. The endeavor for universal development of goals for ecological restoration continues to generate many discussion and controversy. I discuss the importance of restoration goals and diverse roots of restoration ecology, and show how the complex lineages within restoration ecology. I review the three major theme that currently are used to develop the restoration goals : restoration of species, restoration of whole ecosystem or landscapes, and the restoration of ecosystem services. Restoration ecology, landscape ecology and conservation biology share goals to conserve biodiversity, but differ in focus of approach. I review the differences among three fields. Conservation biology has been more zoological, more descriptive, and theoretical, and more emphasized the population and genetic research. However, restoration ecology has been more plant ecological, more experimental, and emphasized the community and plant succession. Landscape ecology has emphasized the interaction of ecosystem and dispersal among populations. I suggest the integration of restoration ecology, landscape ecology and conservation biology. For example, conservation biology will contribute to the preservation of original habitats by population study, restoration ecology will contribute to regenerate damaged ecosystem and ex situ preservation, and landscape ecology will contribute to restoration of population and landscape.

This study tested the usefulness of landscape indices for quantifying forest fragmentation due to linear development projects. Research was carried out in the middle-upper Nakdong River watershed, which has been affected by the expressway building, or national road-widening. Landscape indices were calculated from the forest cover maps before and after road-building using FRAGSTATS 3.1. We could successfully demonstrate the forest fragmentation based on landscape indices; (1) patch size decreased, and edge density and patch density increased (2) roads simplified patch shapes, especially in the larger patches, (3) patch core area size decreased, and core area density increased, (4) the distance increased between the focal patch and each of the other patches within the search radius (=1km) as a result of roads. We suggest several important needs for future researches, including continued investigation of scaling issues, development of indices that measure specific components of spatial pattern, and study of the relationships between forest fragmentation and ecological processes.
