  • The forest vegetation of Mt. Halla national park area. Cheju island, Korea, was classified into six associations in three alliances and two associations in unidentified alliances by Z-M school method as follows: Unidentified alliance Saso-Abietetum Koreanae assoc. nov. Acero-Quercion mongoliae Kim et Yim 1988 Hepatico-Quercetum mongolicae assoc. nov. Saso-Carpinioin laxiflorae all. nov. Saso-Carpinetum laxiflorae assoc. nov. Daphniphyllo-Carpinetum tschonoskii assoc. nov. Asaro-Quercetum serratae assoc. nov. Rhododendro-Pinion densiflorae Kim et Yim 1988 Saso-Pinetum densiflorae assoc. nov. pinus thunbergii community Unidentified alliance Ardiso-Torretum nuciferae assoc. nov. Among them one now alliance and seven new associations were found and marked with "nov."

  • The character species of Abies koreana community in Mt. Halla national park, Korea, and it s nomenclature was reviewed. According to the code of phytosociological nomenclature (Barkman et al., 1986), the association name was corrected from Saso-Abietetum koreanae Yim et al. 1990 nov. in the Korean J. Ecol. 13(2): 101-130 (1990) to Saso quelpaertensi-Abietetum koreanae (Song et Nakanishi) corr. Yim et Kim 1990.

  • The character and differential species of Abies koreana community, a subalpine coniferous forest, on Mt. Hall a and its vegetation unit were reviewed, based on literature published up to date. Song and Nakanish (1985a) originally described Saso-Abietetum koreanae Song et Nakanishi 1985 for the community. At that time, we were fully justified in establishing the nomenclature. Nevertheless, against this nomenclature, Yim and Kim (1990) made a objection, and it was renamed as what is called Saso quelpaertensi-Abietetum koreanae (Song et Nakanishi) corr. Yim et Kim 1990. In their previous study(Yim et al., 1990) being the root of the nomenclature, however, they did not study on the full layers containing the moss layer of bryophyte and lichen for the stratification of the Abies koreana community, in spite of the importance of the species of moss layer for the selection of character and differential species of vegetation units belonging to Vaccinio-Piceetea Br.-Bl. 1939, and also the floristic composition from their study was not compared with that of the vegetation units of the subalpine coniferous forests in Korea Peninsula, Japan, Maritime Province of Siberia and Northeast China. Among the four character species selected by them, it is clear that Maianthemum bifolim and Lonicera maackii are species no having the characteristic value from the phytosociological viewpoint. Besides, Sasa quelpaerthensis described in their nomenclature is a synonym of S. palmata (Suzuki, 1978). Therefore, their nomenclature is invalid and comes under a contravention (Infringement of Priority) to the Code of Phytosociological Nomenclature (Barkman et al., 1986). Saso-Abietetum koreanae was amply justified also by author's recent study (Song, 1991)examined throughout the range of subalpine coniferous forest in Korea. With the discussion of justification of Saso-Abietetum koreanae, a association discussion was brought in the present review.

  • We carried out a phytosociological study on pine forests in Korea with the method of Zurich-Montpellier School. We collected the data of 252 $relev{\acute{e}}s$ from 45 sites in the pine forests throughout the Korean Peninsula and its attached islands. The vegetation of the pine forests was classified into one association, three communities and seven subcommunities as follows: A: Quercus mongolica-Pinus densiflora community, A-1: Typical subcommunity, A-2: Vaccinium korean urn subcommunity, A-3 : Rhododendron micranthum subcommunity, B: Quercus serrata-Pinus densiflora community, B-1: Typical subcommunity, B-2: Juniperus rigida subcommunity, B-3: Styrax japonica subcommunity, B-4: Eurya japonica subcommunity, C: Saso-Pinetum densiflorae Yim et al. 1990, and D: Castanopsis cuspidata var. sieboldii-Pinus densiflora community. The former three communities were integrated into the Lindero-Quercion mongolicae Kim 1990 em. 1992. The Castanopsis cuspidata var. sieboldii-Pinus densiflora community remained to be studied in future to determine the association. The communities of Quercus mongolica-Pinus densiflora community was distributed throughout the montane zone in central-northern part of the Korean Peninsula. Quercus serrata-Pinus densiflora community occupied widely in the sub-montane and hilly areas in central and Southern Korean Peninsula. The association of Saso-Pinetum densiflorae was found in Cheju Island. Castanopsis cuspidata var. sieboldii-Pinus densiflora community were distributed in the warm-temperate zone including islands off the south-west coast of the Peninsula.

  • A project of constructing the first national geodetic VLBI system is in progress by National Geographic Information Institution. However, since there was no former research or project about geodetic VLBI in Korea, a new R&D is necessary on the fundamental design of the system. In this research, a preliminary study about the necessity of geodetic VLBI in Korea and basic specs for an observation center of geodetic VLBI (for example, antenna, receiver, and recorder, etc.) are presented together with the possibility of producing VLBI antenna in Korea.

  • The checklist currently used for Aviation safety inspection performed by ASIs consists of inspection groups and multiple items, it does not have structured hierarchy system which required to efficiently process aviation safety analysis. On this study, through mapping taxonomy of HFACS onto current checklist to secure structured hierarchy system and present a specification on systematic frequency and severity to perform safety risk assessment of detected hazard.

  • The checklist currently used for aviation safety inspection performed by ASIs(Aviation Safety Inspectors) consists of inspection groups and multiple items, it does not have safety attribute and structured hierarchy system which required to efficiently process aviation safety analysis. On this study, categorized the domestic and foreign ASI checklist by safety attribute from ICAO recommended and presented composition of checklist for safety assurance by comparative analysis composition of domestic and foreign ASI checklist.
