This study was examined for purposes of identifing woods of the hull construction collected from a sunken old-ship by the anatomical wood features, and then from the result the geographical distribution ranges of the species were described. Most woods of the hull construction, i.e. shell plating, bulkhead, floor, bulwark, deck and kneel were identified with Chinese red pine (Pinus massoniana), but the fenders were idendified with Chinese fir (Cunninghamia lanceolata). These two species are known to be the endemic species in the south region of Yangtze River. As the other materials, bulwark stays and liquid tank stays were respectively identified with Cinnamomum spp., Distylium spp., and the geographical distributions of these species are the south China, the south coast of Korea and the Japanese Islands.

The preservation has been conducted for wooden ship timber excavated from Bonghwang-Dong, Gimhae, Korea. The species were analyzed for conservation as pre-treatment. Outer panel was analyzed as Cinnamomum spp. and trapezoid wooden material, wooden wedge was Cryptomeria japonica D. Don.. Wooden ship timber have been treated by vacuum-freeze drying after impregnation with aqueous PEG#3,350 solution(almost 45%). The timber of Bonghwang-Dong ship is considered as Japanese ship that many data such as conformation of ship, location of site, japanese artifact of around site were confirmed. In addition, The ship timber give us the important information about the international trade with Japan.

This study is conducted to examine the woods that were excavated at Jangdo Island. The Jangdo site is located in a small island some 180 meters away from the main island of Wando, Jeollanam-do in southern Korea. This site is known as Cheong-Hea Jin fort for the marine King Jang Bogo during the early 9$^{th}$ century. Total of 101 specimens were collected in three groups； small-size piles, log fences (Mok-check) and logs from a well. The species of the group of piles consisted of Quercus spp. (43%), Pinus densiflora (29%), Pinus koraiensis (5%), Alnus japonica (3%), Fraxinus spp. (3%), Styrax obassia (3%), Juglans spp. (2%), Zelkova serrata (2%), Platycarya strobilacea (2%), Celtis spp. (2%), Torreya nucifera (2%), Quercus myrsinaefolia (2%), and Cinnamomum spp. (2%). The species of Mok-check and logs from the well were identified as all Pinus densiflora. The species composition indicated that the climate around A. D. 9th-10th century in southern Korea was similar to the present.. The wooden fences were also examined for tree-ring analysis. The ages of woods were 50∼60 years. We made two site chronologies. The chronologies indicated that southeastern and southwestern fences were repaired frequently. The results could not give the absolute dates due to lack of reference chronologies in this period.

The oils of Acorus gramineus, Cinnamomum sieboldii, Eugenia aromatica, and Inula helenium were tested for their acaricidal activity against Dermatophagoides farinae and D. pteronyssinus. Responses varied according to dose and mite species. As compared to the oils, the oil most toxic to D. farinae and D. pteronyssinus was E. aromatica, followed by C. sieboldii, A. gramineus, and I. helenium. On the basis of $LD_{50}$ values of the oils in A. gramineus, C. sieboldii, and E. aromatica, the compound most toxic against D. farinae and D. pteronyssinus was eugenol congeners (isoeugenol>eugenol>acetyleugenol) followed by benzyl benzoate, salicylaldehyde, safro1, DEET, cinnamyl alcohol, and 3-carene. As a naturally occurring acaricide, these oils and eugenol congeners could be useful as new acaricidal agents against Dermatophagoides spp.

This study was carried out to provide examples of planting methods for the construction of street green spaces with abundant greenery by analyzing road type, surrounding land use and planting structures in street green spaces on Port Island, Kobe, Japan. Port Island_(total area: 826ha) is a marine cultural city located in Japan's first artificial island with facilities of urban function and port facilities. The study site was designated at 11 plots of $55{\sim}285m^2$ on Port Island, and topography structure styles were divided into four types with mounding style, slope style, slope and flat style, flat style according to the adjacent roads width. The area adjacent to the middle roads with high levels of noise and pollution set up the mounding style, slope style, slope and flat style of multi-layer structures using topographic properties. The area adjacent to small roads focused on a green strip with shrubs on a flat style. Surrounding land-uses include a public institution, housing complex, and a commercial building. The planting concept was a buffer and landspace function in case of the middle road_(lane 4) while the small road_(lane 2) was a landspace function. Planting species were diverse with Liquidambe formosana, Cinnamomum camphora, Sapium sebiferum, Cedrela sinensis, Laeocarpus sylvestris var. ellipticus, Ginkgo biloba, Prunus serrulata var. spontanea, Zelkova serrata, Quercus glauca, Juniperus chinensis, Magnolia kobus, Rhododendron spp., Camellia japonica, Abelia mosanensis, etc. Planting density was 0.02~0.08(0.04) individual/$m^2$ at the canopy layer, 0.02~0.08(0.04) individual/$m^2$ at the understory layer. Ratio of green coverage was 40.0~173.7(93.0)% at the canopy layer, 2.1~79.8(34.9)% at the understory layer and 17.9~64.2(32.9)% at the shrub layer. $Gr{\ddot{u}}volumenzahl$ was $1.43{\sim}6.67(4.13)m^3/m^2$ at the canopy layer, $0.02{\sim}2.01(0.85)m^3/m^2$ at the understory layer and $0.14{\sim}0.58(0.26)m^3/m^2$ at the shrub layer. The ratio of green coverage of street green space on Port Island was higher than that of Seoul, and particularly, the ratio of green coverage and $gr{\ddot{u}}volumenzahl$ at the shrub layer differed, compared to the main street green space in Korea. The result of this study may be applicable to other coastal reclaimed cities in terms of setting methods for street greenery considering the topography structure, planting structure and planting function.
