This study was carried out to investigate the flora of uninhabited Island in the Deokjeok Archipelago. The vascular plants which were collected in 5 times (from Jun. 2009 to Apr. 2010) were identified as 350 taxa in total, including 89 families, 231 genera, 309 species, 5 subspecies, 31 varieties, and 5 forms. There were many useful plants such as 2 taxa of Korean endemics and 2 taxa of rare plants which were proposed by the Korea Forest Service. The specially determined plants which were categorized as 5 degrees in all by the Ministry of Environment appeared as 49 taxa; Degree V was one taxon; Senecio nemorensis and IV was one taxon; Apocynum lancifolium and III was 2 taxa; Stauntonia hexaphylla, Hylotelephium spectabile and I was 45 taxa; Machilus thunbergii, Neolitsea sericea, Hedera rhombea, etc. Based on the plants which were approval objects when transfer overseas were 5 taxa, and 21 taxa of evergreen plants were recorded in the investigated area. The naturalized plants were identified as 15 taxa, and their naturalization ratio were found to be 4.2% respectively.

Objective: This meta-analysis was conducted to evaluate the overall effect of direct-fed microbial (DFM) or probiotic supplementation on the log concentrations of culturable gut microbiota in broiler chickens. Methods: Relevant studies were collected from PubMed, SCOPUS, Poultry Science Journal, and Google Scholar. The studies included controlled trials using DFM supplementation in broiler chickens and reporting log concentrations of the culturable gut microbiota. The overall effect of DFM supplementation was determined using standardized mean difference (SMD) with a random-effects model. Subgroups were analyzed to identify pre-specified characteristics possibly associated with the heterogeneity of the results. Risk of bias and publication bias were assessed. Results: Eighteen taxa of the culturable gut microbiota were identified from 42 studies. The overall effect of DFM supplementation on the log concentrations of all 18 taxa did not differ significantly from the controls (SMD = -0.06, 95% confidence interval [-0.16, 0.04], p = 0.228, $I^2=85%$, n = 699 comparisons), but the 18 taxa could be further classified into three categories by the direction of the effect size: taxa whose log concentrations did not differ significantly from the controls (category 1), taxa whose log concentrations increased significantly with DFM supplementation (category 2), and taxa whose log concentrations decreased significantly with DFM supplementation (category 3). Category 1 comprised nine taxa, including total bacterial counts. Category 2 comprised four taxa: Bacillus, Bifidobacterium, Clostridium butyricum, and Lactobacillus. Category 3 comprised five taxa: Clostridium perfringens, coliforms, Escherichia coli, Enterococcus, and Salmonella. Some characteristics identified by the subgroup analysis were associated with result heterogeneity. Most studies, however, were present with unclear risk of bias. Publication bias was also identified. Conclusion: DFM supplementation increased the concentrations of some beneficial bacteria (e.g. Bifidobacterium and Lactobacillus) and decreased those of some detrimental bacteria (e.g. Clostridium perfringens and Salmonella) in the guts of broiler chickens.

The vascular plants of the studied area in the Mt. Bangjang was listed 422 taxa : 106 families, 299 genera, 372 species, 1 subspecies, 46 varieties and 3 forms. Based on the list of the rare plants by the Forest Research Institute, 5 taxa were recorded in the studied areas; Lilium distichum(Preservation priority order : No. 159), Tricyrtis dilatata (No. 97), Aristolochia contorta (No. 151), Prunus yedoensis (No. 110), Patrinia saniculaefolia (No. 122) and based on the list of Korean endemic plants, 9 taxa were recorded; Cephalotaxus koreana, Carex okamotoi, Populus tomentiglandulosa, Salix purpurea var. japonica, Prunus yedoensis, Forsythia koreana, Paulownia coreana, Weigela subsessilis, Patrinia saniculaefolia. Specific plant species by floral region were total 29 taxa; Prunus yedoensis in class V, 3 taxa(Acer palmatum, Asperula lasiantha, Lonicera subhispida ) in class III, 5 taxa(Lilium distichum, Potentilla dickinsii, Caryopteris incana, Patrinia saniculaefolia, Ligularia fischeri) in class II, 20 taxa(Ulmus parvifolia, Clematis patens, Aconitum jaluense, Ilex macropoda, Grewia biloba var. parviflora etc.) in class I. The naturalized plants in this site were 13 families, 31 genera, 36 species, 2 varieties, 38 taxa and naturalization rate was 9.0% of all 422 taxa vascular plants. Because of recent rapid increase of cars and people around here, analysis shows many naturalized plants and high naturalized ratio. And wild plants disturbing ecosystem like Ambrosia artemisiifolia var. elatior have been increasing. So, it needs continuing control and conservation measures on the plant ecosystem.

팔장고말속 식물은 전세계적으로 1,000 분류군 이상이 보고되어 있으나 한국에서는 68종 42변종 9품종의 119분류군이 보고 되어있다. 본 연구에서는 2003년 2월부터11월에 걸쳐 전국의 15개의 호소 및 저수지로부터 23분류군의 한국산 팔장고말속을 채집하였다. 이중 Staurastrum affine을 포함한 12분류군은 한국산 미기록종으로 추가되었다. 따라서 현재까지 한국산 팔장고말속 식물은 77종 45변종 9품종의 총 131분류군으로 정리되었다. 본 연구에서 관찰된 많은 종들은 국외에서 이미 보고된 개체들의 형질과 일치하였으나, S. affine을 포함한 8분류군들은 이미 보고된 개체들에 비하여 세포의 크기가 작았다. 또한 S. ceratesa등 7분류군은 반세포의 형태와 세포벽의 장식 등에 있어서 차이를 나타냈다.

프랑스 식물분류학자 $L{\acute{e}}veill{\acute{e}}$, A. A. H.가 Decades plantarum novarum이라는 연속 논문에서 Faurie와 Taquet 신부 등이 국내에서 채집한 표본들을 근거로 발표한 다수의 신분류군의 분류학적 실체를 파악하기 위하여, 지금까지 이들 분류군에 대한 분류학적 견해를 비교 검토하였다. 이중 다른 분류군과 동일한 것으로 간주되는 분류군은 146개로 확인되었다. 이들 중 Ajuga devestita 등 79개 분류군에 대해서는 일치된 분류학적 견해가 도출되었으나, Bidens robertianifolia 67개 분류군은 학자들마다 상충된 분류학적 견해가 도출되었고, Aconitum coreanum 등 8개 분류군은 후일동음명 등과 같은 이유로 비합법명이었다. 한편, Rhododendron hallaisanense 등 5개 분류군은 학자에 따라 독립된 분류군으로 간주되기도 하였다.

This study was conducted to investigate the vascular plants which can be an indicator of environmental change in Seseok of Jirisan National Park. The purpose of this study was to find out the basic information for the subalpine species. This study showed that the area had a total 295 taxa including 63 families, 177 genus, 252 species, 2 subspecies, 36 variants 5 forms and Pte-Q was 1.7. Among them, Korea endemic plants were 15 taxa such as Abies koreana. Rare plants were 14 taxa such as Viola diamantiaca. Naturalized plants consisted of 5 taxa such as Rumex crispus. The floristic regional indicator plants found in surveyed area were 72 taxa comprising 3 taxa of grade V, 7 taxa of grade IV and 24 taxa of grade III. In summary, The subalpine plants of the survey region consisted of 37 taxa including Abies koreana and Gymnadenia cucullata. As rare plants distributed in subalpine zone respond sensitively to climate change, accuracy distribution range, environmental characteristics of habitat and population dynamics of rare plants should be evaluated quantitatively.
