  • The goal of this manuscript is to determine seed-borne plant pathogenic bacteria and phytoplasmas among quarantine pests in Korea. Four and two prohibited bacteria and phytoplasmas, respectively, and 35 and 17 restricted bacteria and phytoplasmas, respectively, were assessed whether they are seed-borne or not based on preliminary reports. As results, two species of prohibited bacteria, eighteen species of restricted bacteria, and one species of restricted phytoplasma have been determined as being seed-borne plant pathogenic bacteria. Thus, quarantine fields must account for these lists once inspection has been conducted on imported seeds and also use of these lists can help to reduce the production of new diseases that can spread from infected imported seeds.

  • Linear development such as road and railway construction is considered to be an important factor in the dipersion agent of alien species. The purpose of this study is to investigate the effect of road project implementation on the introduction of alien plants. We selected the roadworks that have been completed or completed by more than 70% of the projects in the Han River basin environment agency. The alien plant data were divided into five phases: pre-construction (P0) and construction (P25, P50, P75, P100) according to the annual process rate. As the construction progresses, the naturalization rate, the urbanization index and the tendency of the number of exotic plants increase. Especially, alien plants were introduced rapidly at the beginning of the construction period, and the introduced species continued to appear until the construction was completed. Therefore, it is necessary to minimize the introduction of ailen plants by concentrating management of embankment process and the vegetation restoration process at the beginning of roadworks.

  • This study aims to examine the traditional living space to reflect the environment-friendly design methods and principles of reestablishment. To do so, this study carried on a related literature study and field survey. The traditional living space in terms of the environmental friendliness is reflected on site selection and space composition, and utilization of natural energy and natural materials. Focused on the Kwangajeong in Yangdong Village, this study is to identify eco-friendly techniques on the traditional living space. As a result, it shows that Kwangajeong with the side of the southeast in site selection had been considered in aspect of environmental control such as sunshine and solar radiation. Also building construction techniques had been used to minimize the variation of terrain. In aspect of environmental conservation, Kwangajeong had structurally arranged the gate, an inner yard and an inner floor to allow good ventilation. In aspect of space composition, Kwangajeong with the emphasis of scenic view had utilized the methods that attract external landscape through the control of its fences. Environment-friendly techniques and control principles in traditional space had been developed by a long experience through the long periods and the traditional techniques suitable for local climate and local environment have been developed. The technical development of these techniques to resolve the global environmental and energy issues and create a more pleasant living environment of human beings might be critical.
