This study investigated species formation and their vegetation on the roadsides of 1100 Road and 5 16 Road in Hallasan National Park from August 2004 to December 2006 to provide basic data for distributional attribute of the naturalized plants. The vascular plants investigated on the roadsides of Hallasan National Park were found to be 62 families, 145 genera, 197 taxa in total, in which naturalized plants were recorded as 11 families, 29 genera, and 37 taxa. The floristic formation at 1100 Roadside was composed of Festuca arundinacea-Dactylis glomerata association, which was again divided into Trifolium pratense-Plantago lanceolata sub-association and Sasa quelpaertensis-Gleichenia japonica sub-association. The florisitic composition of the 5 16 Roadside was sorted as Festuca arundinacea-Dactylis glomerata association, Oplismenus undulatifolius-Potentilla fragarisiiforlia, elatior association, Ambrosia artemisiifolia, and etatior-Persicaria thunbergii association. Among the naturalized plants distributed at this area, the annual plant accounts for 51.4%[19 taxa] and the plant of European origin accounts for 70.3%[26 taxa]. As for the background of the introduction of these plants, the case of introduction for forage or a mixture with grain and for pasture was 35.1% and 21.6% respectively, showing higher introduction circumstances than others. As shown in the study, most of the roadsides were occupied by the naturalized plants- Festuca arundinacea and Dactylis glomerata association and various naturalized plants; thus we can assume that it's because Festuca arundinacea and Dactylis glomerata association were mostly used for re-vegetation of the destroyed areas due to road construction or expansion or road maintenance and improvement project.

This study was performed to determine the quality characteristics of Jeung-Pyun with added tapioca flour. With increasing tapioca flour content, the moisture content of the product was decreased. The addition of tapioca flour increased the volume and symmetry compared to the control with no tapioca flour. The highest uniformity was shown by the 10% added group, but the differences were not significant. In the Hunter's value, the lightness of the control was higher than that of the group with added tapioca flour. Whereas the reverse was the case for the yellowness. With increasing tapioca flour content, the springiness, gumminess, cohesiveness, and chewiness of Jeung-Pyun were increased, and the hardness increased. In sensory evaluation cell uniformity and chewiness were the highest in the 20% added group. The hardness of the sense examination increasing with increasing tapioca floor content. The overall quality of Jeung-Pyun was the lowest in the 30% added group.

Tofu was prepared with various herbs (green tea, rosemary, lavender and thyme) and the tofu quality was investigated during storage. In the measurement of tofu color, the L and b values increased during storage period. Especially, the b value was very high at 8 days after storage. The pH value of tofu increased until 6 days of storage, but then decreased. The turbidity gradually increased until 6 days of storage and rapidly increased at 8 days of storage. The microorganism count of herb tofu was lower an that of control tofu during storage. Especially green tea tofu showed the lowest psychrotrophic microorganism count as $1.3{\times}10^8\;CFU/g$. In addition, lavender tofu showed the lowest aerobic mesophilic microorganism count $(2.0{\times}10^7\;CFU/g)$ at 8 days of storage. In texture analysis, hardness and chewiness of herb tofu increased with increasing storage period. Springiness increased to 2 or 4 days of storage but decreased after 6 or 8 days. Therefore, herb tofu is expected to have good quality physiologically as well as microbiologically.

Vegetation structure of the vascular plants was investigated from March 2003 to October 2003 in Haepyeong wetland, Gumi-si, Gyeongsangbuk-do, Korea. Actual vegetation of Haepyeong wetland largely can be classified by floristic composition and physiognomy into 18 communities; Xanthium strumarium-Digitaria sanguinalis, Humulus japonicus, Persicaria perfoliata-Humulus japonicus, Phragmites japonica-Miscanthus sacchariflorus, Persicaria hydropiper-Phragmites communis, Persicaria hydropiper, Phragmites japonica-Persicaria hydropiper, Miscanthus sacchariflorus- Phragmites japonica, Persicaria hydropiper-Phragmites japonica, Miscanthus sacchariflorus-Salix glandulosa, Salix nipponica-Salix glandulosa, Salix nipponica-Salix koreensis, Salix nipponica, Miscanthus sacchariflorus-Salix nipponica, Phalaris arundinacea-Salix nipponica, Salix glandulosa-Salix nipponica, Trapa japonica, and Ceratophyllum demersum-Trapa japonica. Among them, the area of the Salix nipponica-Salix koreensis community was the largest as 122.2ha(9.23%). The dominant vegetation type was Miscanthus sacchariflorus-Persicaria hydropiper community based on phytosociological method, and it was was classified into three subcommunities; Salix glandulosa-Salix nipponica subcommunity, Digitaria sanguinalis subcommunity, and Cyperus amuricus subcommunity. Differential species of Salix glandulosa-Salix nipponica subcommunity were Salix nipponica, S. glandulosa, S. koreensis, Scirpus radicans, Persicaria maackiana, and Achyranthes japonica; differential species of Digitaria sanguinalis subcommunity were D. sanguinalis, Setaria viridis, Ambrosia artemisiifolia var. elatior, and Cyperus orthostachyus; differential species of Xanthium strumarium subcommunity were X. strumarium, Acalypha australis, Erigeron canadensis, Echinochloa crus-galli, and Vicia tetrasperma. Zonation of vascular hydrophytes and hygrophytes was as followers: Salix glandulosa, S. koreensis, S. nipponica were distributed in the region of land which water table is low, and Persicaria maackiana, Persicaria hydropiper, Scirpus radicans were distributed in the understory. And emergent plants such as Phragmites communis and Scirpus karuizawensis, floating-leaved plant such as Trapa japonica, submersed plant such as Ceratophyllum demersum, and free floating plant such as Spirodela polyrhiza formed the zonation from shoreline to water. The specified wild plants designated by the Korean Association for Conservation of Nature, Ministry of Forest, and Ministry of Environment were not distributed in the study area. It was expected that Haepyeong Wetland worthy of conservation contributed purifying water pollution, giving habitats of many lifes, and providing beautiful scenes of the river.
