The thermal decomposition process of Mo(CO)_6 on chemical vapor deposition was investigated by analyzing the effects of deposition temperature, pressure, and reaction gas on the phase change of deposited films. Mo_2C was deposited at or below 350℃ due to the incompleteness of thermal decomposition of Mo(CO)_6, but Mo films was successfully deposited at 400℃ or higher temperatures. The variation of deposition pressure did not change the dependence of decomposition process on deposition temperature. The activation energy of surface reaction was 5.8 ㎉/mole.

The Plant resources of Narodo Islands ( Naenarodo Islet, Oenarodo Islet, Sayangdo Islet, Aedo Islet, and Surakdo Islet) were investigated 13 times from March 24, 1984 to November 30, 1985. In order to analyze the vegetation of these islands, vegetation structure, distribution and utilities of plants, and actual vegetation map of them were prepared. Vascular Plants of these islands, consisted of 8 forma, 92 varieties, 2 subspecies, 665 species, 490 genera, and 130 families, alternatively, there were 272 species of woody plants and 495 species of herbs. These woody plants and herbs were reclassified with their utilities as 405 species for edible resources, 460 species for medicinal resources, 104 species for ornamental resources, 1 species for fiber resources, 280 species for industrial r-ough resources, and 118 species for feed resources. Since Narodo Islands are situated on the warm temperature forest zone, they are full of the temperate diagnosis trees with 61 species of evergreen broadleaf trees. Furthermore, the natural vegetation of them consisted of two stand units :l) evergreen broadleaf forest including Castanopsis cuspidata var sieboldii, Castanopsis cuspidata var, thunbergii, Camellia japonica, Sageretia theezans, Machilus thunbergii, Pittosporum tobira, Ligustrum japonica, Ardisia japonica, Ouercus myrsinae, and Parabenzoin trilobum and 2) Pinus thunbergii forest. The confficient of cryptogam(Pte-Q)and urbanization index (UI) as to destruction degree of natural vegetation showed a value of 1.27 and 19.25, respectively. The vegetation around densely populated villages was destructed. The average values of the degree of green naturality (DGN) of the investigated area were 3.78 at Naenarodo Islet and 5.42 at Oenarodo Islet. These data showed that the vegetation of Oenarodo Islet was well preserved. On the order hand, the community of Castanopsis cuspidata var, sieboldii and Camellia japonica at Shingum ferry terminal, Lycoris albiflora, Parabenzoin trilobum, Neofinetia falcata, Cymbidium goeringii, and Dendrobium moniliforme, etc. were feared to be destructed in their vegetation as the result of the development of Narodo Islands as a tourist resort. Therefore, it is desired that a proper control system be taken for their preservation.
