  • The distribution of three typical warm-temperate evergreen trees, Quercus acuta Thunb., Neolitsea sericea (Blume) Koidz., and Machilus thunbergii Siebold & Zucc., were surveyed on the Korean Peninsula based on field and specimen investigations and the distribution maps of the three species were prepared. The distribution patterns of the species correspond to the south coast floristic region in Korea, which includes the distributional areas of Jeju-do, Isl. Ulleung, the southern coastal areas, and the areas up to the islands around Incheon in the Yellow Sea. The northernmost limit of the distribution of Quercus acuta is Isl. Nap of Incheon in the west, and a new distribution was found at Isl. Ulleung in the East Sea; additionally, the limit of Neolitsea sericea is the Deojoek archipelago of Incheon. The northernmost limit of Machilus thunbergii is Isl. Daecheong of Incheon, which is the highest latitude among those of the three species. This distribution survey of evergreen broad-leaved trees in Korea can be used as basic data for the delimitation of floristic regions and as a bio-indicator of climatic change.

  • The purpose of this study was to propose a measure for eco-cultural regeneration by a detailed examination of closed down schools, old defective residences, deteriorated industrial facilities and space no long in use located throughout Ijak-do. The reserch method utilized a selection of the major elements from the eco-cultural regeneration element of island regions and a measure for application and regeneration on the deteriorated facilities of Ijak-do was proposed.

  • This paper is a research that investigated the distribution and status of coastal sand dunes spread along the shoreline of Ongjin-gun, Jung-gu in Incheon and evaluated their conservation status. In Incheon, the length of coastline along the West Sea shoreline is 1,053km. thus leading to an assumption that coastal sand dunes are dispersed their as many as other regional local government. However, there are no enough basic data on the distribution, characteristics, and the management status of other areas besides the 5 places on the list by the Ministry of Environment. Considering this fact, this paper additionally drew 21 coastal sand dunes in the shoreline of Incheon, including the 5 places on the list by the Ministry of Environment, through the standard of coastal sandhill selection. The additionally selected aimed to propose how to develop basic materials on the conservation status of coastal sandhills in Incheon through characteristic analysis by sandhill and qualitative evaluation.

  • Mineralogical study was carried out for heavy minerals in the sea sand near Ongjingun bay, Kyonggi-do separated using the gravity and magnetic separators. Ilmenite, zircon and minor monazite and garnet were valuable minerals with gangue minerals of quartz, K-feldspar, plagioclase, muscovite, hornblende, epidote and chlorite. Quantitative analysis with SIROQUANT program showed that the contents of ilmenite separated with the gravity separation (the shaking table separation), the 1st step magnetic separation (rare earth magnetic separation) and the 2nd step magnetic separation (the Eddy current magnetic separation) were increased into 0.8, 18.3, and 48.7%, respectively. The content of ilmenite, monazite and zircon were recalculated based on the chemical composition of the representative and heavy fraction products of raw sand, the 1 step and 2 step gravity separations, and the 1 step and 2 step magnetic separations. The content increased to 0.23, 0.55, 5.22, 16.17, and 44.99% in ilmenite, 0.11, 0.02, 0.16, 0.51, and 1.19% in monazite. Although the zircon content did not differ over the processes (0.13, 0.12, 0.11, 0.15, and 0.10%), the improved recovery of zircon is expected by applying sieving process because of its high content (27%) in the fine grain size fraction (< 140#) of the 2 step gravity separation.

  • We report for the first time a taxon of the genus Thyrocarpus (Boraginaceae) from Daecheongdo, Ongin-gun, Incheon-si in Korea. This taxon appears to be Thyrocarpus glochidiatus Maxim., previously known from China. The new Korean name, 'Dae-Cheong-Ji-Chi', was given considering the name of discovered location. A description, an illustration and a photograph were given.
