The materials that are involved in urban landscaping include plants and the associated animals, soil, water, and other environmental elements. And biodiversity is the substantial base for human beings. The conservation of biodiversity is of great importance in the sustainable development of the society and should not be neglected in the development of sustainable urban landscape. The conservation of biodiversity should be included in the urban landscape planning. The conservation of biodiversity should be emphasized in the construction of urban green space. Every possible opportunity should be used to conserve the species diversity, genetic diversity and ecological diversity. The assessment of biodiversity conservation should be introduced into modern landscape planning.

Following the previous ones, this study is intended to explore methods of qualitative assessment on the view from apartment units. It first complemented and analyzed the attributes of landscape elements and then set up questionnaire items based on these attributes to identify the tendencies in apartment inhabitants' recognition of landscape elements, and then conducted a preference assessment on the test cases sampled on the basis of picture and other data collected in the previous studies to identify the characteristics of the preference for the view from apartment units according to landscape elements. Consequently, the following results have been derived. First, the landscape elements seen from apartment units may be classified into a total of sixteen categories, and the overall ratio of natural elements to artificial ones is shown to be approximately one to three. Second, it is also shown that apartment dwellers tend to prefer natural landscape elements over artificial ones, and the preferences for the distance to and location of landscape elements exhibit certain variance depending on the type of the elements. Third, the analysis of the preference for landscape elements has revealed that the types of landscape elements, the make-up and diversity of landscape elements, and the perceived distance to landscape elements as well as the resultant feeling of openness all affect the preference tendencies.

This study analyzed rural experiential educational programs that are currently in operation and examined the programs' reflection of Education for Sustainable Development (ESD) to explore the significance of those programs in terms of the ESD. In particular, this study analyzed cases of rural experiential educational programs from four villages in the capital region, Gyeongsang, Jeolla, and Chungcheong. The analysis results are as follows. Four villages' experiential educational programs share similar activities, such as nature experience, farming, traditional food and culture, games in nature, and craft. Each village has special programs and managements according to their geographical and environmental conditions. In addition, those programs are related to the ESD elements of health food, and cultural diversity (in sociocultural area) and of species diversity and environmental issues (in environmental area). On the other hand, the ESD elements in economic areas are not related to those programs. In addition, most of the villages plan and run experiential educational programs to keep and develop their own villages' sustainability. Rural experiential educational programs need to include various elements of ESD to develop rural communities.

Post-modern society leads us to accept diversity and variability instead of pursuit of the absolute truth, beauty or classical value systems, thus leading to hybrid phenomena. The purpose of this study is to analyze characteristics and expressive effects of hybrid expressions through which to provide conceptual bases for interpreting expanded meanings of fashion illustrations that express aesthetic concepts of hybrid culture. Hybrid refers to a condition on which diverse elements are mixed with each other, so any one element can not dominate others. It is often used to create something unique and new by a combination of unprecedented things. Hybrid can be classified into four categories: temporal hybrid, spatial hybrid, morphological hybrid and hybrid of different genres. Temporal hybrid from a combination of past and present in fashion illustration includes temporal blending by repetition and juxtaposition. Spatial hybrid shows itself in the form of inter-penetration and interrelationship by means of projection, overlapping, juxtaposition and multiple space. Morphological hybrid expresses itself through combination of heterogenous forms and restructuring of deformed forms. Hybrid of different genres in fashion illustration applies various graphic elements or photos within the space, and represents blending of arts and daily living. Such hybrid expressions in fashion illustrations reflect the phenomena of diversity and variability of post-modern society. Hybrid expressions in fashion illustrations predict endless possibility of expressing new images through combining various forms or casual elements and can develop toward a new creative technique.

This paper aims to study on bibliographic reference forms, especially focused on the forms of korean sources. Although bibliographic reference is one of the critical elements in academic works, it seems every work has it's own forms in Korea. The fact that the bibliographic reference forms in korean works are made up by option causes the present state of diversity which makes difficulty in bibliographic control. The results of this search into internal academic journals show the diversity in the entry of title and significant gap of bibliographic reference forms among disciplines.

This study examined the Chinese style in the Vivienne Tam collection as well as explored diversity and modern interpretation of a Chinese style used in modern fashion. The study also investigated the concept and history of the Chinese style as well as analyzed the Chinese style in the collection based on a consideration of a Chinese element that is the basic structure with an understanding of Vivienne Tam and general collection themes. As a result of research, the Chinese style appeared in the Vivienne Tam collection was comprehensive with 43 Chinese elements including Animals, Flower & Grass among the Nature elements, Mythology Religion among the Figure elements, Historical Artifacts, Clothing, Oral Literature, Entertainment, Fine Arts. Technique, Folk holiday among Culture elements and Philosophy among Spirit elements, which accounted for 57.6% of the collection. The formative characteristics that included Chinese elements were extended, abstracted, distorted or transformed; in addition, some abstract elements were embodied into animals, images and certain particular forms to present a theme. In addition to two-dimensional method to print Chinese elements on fabric, they were also expressed as a three-dimensional texture or a silhouette, achieving clear and bold harmony. The aesthetic characteristic is a mixture of Eastern and Western way of thinking. Her costume has a political and historical meaning beyond the imitation of elements that represent the development of a pleasant and interesting design.

The continuous increase in the production of metals and their subsequent release into the environment has lead to increased concentration of these elements in agricultural soils. Because microbes are involved in almost every chemical transformations taking place in the soil, considerable attention has been given to assessing their responses to metal contaminants. Short-term and long-term exposures to toxic metals have been shown to reduce microbial diversity, biomass and activities in the soil. Several studies show that microbial parameters like basal respiration, metabolic quotient, and enzymatic activities, including those of oxidoreductases and those involved in the cycle of C, N, P and other elements, exhibit sensitivity to soil metal concentrations. These have been therefore, regarded as good indices for assessing the impact of metal contaminants to the soil. Metal contamination has also been extensively shown to decrease species diversity and cause shifts in microbial community structure. Biochemical and molecular techniques that are currently being employed to detect these changes are continuously challenged by several limiting factors, although showing some degree of sensitivity and efficiency. Variations and inconsistencies in the responses of bioindicators to metal stress in the soil can also be explained by differences in bioavailability of the metal to the microorganisms. This, in turn, is influenced by soil characteristics such as CEC, pH, soil particles and other factors. Therefore, aside from selecting the appropriate techniques to better understand microbial responses to metals, it is also important to understand the prevalent environmental conditions that interplay to bring about observed changes in any given soil parameter.

We surveyed the vegetation of an ecological landscape preservation area (legally protected conservation areas or national parks) and the surrounding areas of Mt. Cheonggye, Republic of Korea, to explore the conservation implications for preservation areas and surrounding transition areas. We calculated diversity indices to identify the properties of the preservation and surrounding areas that are relevant to conservation efforts. We then compared the plant community composition between the areas using field and quadrat surveys in the preservation and surrounding areas. The cover of the dominant species in all tree and herb layers was markedly higher in the preservation area than in the peripheral zones. The species richness indices were significantly higher in the preservation area than in the peripheral zones. Ordination using detrended canonical correspondence analyses showed that the cover of the dominant tree species and rocks could explain the distribution of plant species in the Cartesian space of the ordination. Our results demonstrate that physiognomically designated protected areas match well with ecological data based on diversity indices and ordination analyses and that disturbances in the areas surrounding the ecological landscape of preservation areas can have considerable impacts on plant diversity indices. Hence, the preservation and management of surrounding areas are essential conservation elements for protecting the entire ecological landscape of preservation areas.

The creative energy of the Korean women who pursued spiritual artistic practices under the limited situation of male-dominated confucian society in the Chosun Dynasty(AD 1392 - AD 1910) constituted the background for the development of Gubang Craft. Gubang Craft represented their artistic abilities, moral and family values, and the pursuit of self-esteem. Especially embroidery successfully showed four main elements of Gubang Craft such as embellishment, diversity, femininity, and craftsmanship. This paper is designed to explore how the traditional elements of embroidery works are restored and have influence on the modern Korean fiber art.
