1996년 2월부터 8월까지 총 3회 11일간 설악산 국립공원 외설악과 인근지역의 관속식물상을 조사한 결과, 101과 379속, 659종, 2아종 105변종 8품종 총 774종류(taxa)로 조사되었다. 이중에서 외설악 지역에는 89과 321속, 526종 2아종 89변종 3품종중 총 620종류(taxa), 점봉산 지역은 86과, 251속, 350종, 1아종 51변종 2품종 총 404종류(taxa)로 각각 조사되었다. 외설악 지역에서는 남쪽에서 자라는 개족도리와 대팻집나무의 자생지를 확인하였고, 점봉산 지역에서는 신포동의 산외, 관모봉 지역에서는 참배암차즈기 등 6종류의 희귀식물을 발견하였다. 확인한 북방인자의 식물로는 분비나무, 눈잣나무, 눈측백, 등대시호, 두메부추, 금강봄맞이, 만주송이풀, 말나리, 붉은인가목, 솜다리, 톱바위취 등 17종류, 남방인자의 식물로는 사람주나무, 대팻집나무, 때죽나무, 지리대사초, 개족도리, 암대극등 6종류로 조사되었다. 또한 겨울철 도로교통의 안전을 위하여 뿌린 바닷가 모래의 영향으로 갯씀바귀, 갯완두, 참골무꽃, 해당화 등 해안지역에 주로 생육하는 식물이 도로를 따라 산악 내부까지 침투하고 있음을 확인하였다.

Cedrus deodara (Pinaceae) has been used traditionally in Ayurveda for the treatment of central nervous system disorders. 3,4-bis(3,4-dimethoxyphenyl)furan-2,5-dione (BDFD) was isolated from heart wood of Cedrus deodara and was shown to have antiepileptic and anxiolytic activity. Thus, the present study was aimed to explore its anti-depressant effect and to correlate the effect with serotonin and nor adrenaline levels of brain. Albino mice were used as experimental animal. Animals were divided in to three groups; vehicle control, imipramine (30 mg/kg i.p.), BDFD (100 mg/kg i.p.). Tail suspension test (TST) and forced swim test (FST) was performed to evaluate antidepressant effect of BDFD. BDFD (100 mg/kg, i.p.) showed a significant decrease in immobility time when subjected to FST whereas immobility time was not significantly altered in TST. BDFD treatment increased serotonin and noradrenaline levels in the brain which is indicative of BDFD having possible atypical antidepressant action.

Leptoglossus occidentalis Heidemann, 1910 was newly recorded in Korea as a invasive species at Gyeongsangnam-do, Korea in 2010 and 2011. Leptoglossus Guerin-Meneville, 1831 is also newly recorded Coreid genus in Korea. The diagnostic shape is expanded leaf-like hind tibiae. The origin of this species is North America and it has been rapidly propagated around the world as a pest. This bug recognized as a pest on almost of Pinaceae plants and they suck on developing cones, so the monitoring on the present invasion of this species in Korea is urgent. It was presumed that the invasion of Leptoglossus occidentalis into Korea was before 2010 with present study.

This study was conducted to assess the existing flora and fauna, and to develop a spatial map of Alapang communal forest located in the province of Benguet, Philippines. A total of 52 species belonging to 27 families were identified during the inventory in this communal forest using the quadrat method while a total of 30 species belonging to 18 families were recorded using line intercept technique for the assessment of grasses, herbs, vines and other low-lying vegetation. The diversity index of the species in Alapang communal forests using the quadrat method was 2.6649 while for the line intercept technique it was 2.5446. The most dominant species in this area was found to be Pinus kesiya Royle ex Gordon (Benguet pine) under Family Pinaceae with an importance value of 106.74%. In the faunal assessment, four species of birds and a small mammal particularly a rodent were identified during the study. Aside from the high species diversity of this communal forest, the presence of endemic and indicator species in the area denotes that this forest was still in good condition hence must be protected. Spatial maps and database system were generated based from data gathered in the field using Geographic Information System (GIS).

화악산, 설악산, 함백산에 서식하는 눈측백의 잎에서 내생균을 분리하여 다양성을 조사하였다. 숙주식물로부터 총202개의 균주를 분리하였고, 이 균주들의 ITS rDNA 염기서열을 분석한 결과 32개의 분류군으로 동정되었으며, Diaporthe nobilis, Mycosphaerella handelii, Pestalotiopsis cocculi 3종이 국내 미기록종으로 확인되었다. 분리된 균주 중 61.5%는 Dothideomycetes였으며, 27.0%는 Sordariomyetes, 11.5%는 Leotiomycetes에 속하였다. 눈측백에 서식하는 내생균에서 우점종은 Dothideomycetes에 속하는 Phyllosticta spinarum인 것으로 조사되었으며 이 종에 대한 후속연구가 필요한 것으로 생각된다.

The order of Rhododendro-Quercetalia mongolicae representing temperate oak forests in Korea was characterized in terms of presence of taxa of different rank. 140 releves were analysed for percentage contribution of each species, genera and families in syntaxa under consideration as well as extracton of diagnostic genera and families for syntaxa by an ordination technique. The Rhododendro-Quercetalia is characterized by high diversity of tree and shrub species contributing 40% of the total floristic composition as well as by a high contribution of the genus Rhododendron and the absence of the genus Fagus, characteristic of the QuercoFagetea sensu lato. The character families for the Rhododendron and Quercus include Liliaceae and Compositae, whereas Acer, Carex, Viola, Rhododendron and Quercus are the most common among genera. Rhododendron and Quercus are regarded as the transgressive cheractergenera, whereas the families of Pinaceae and Ericaceae are considered companions (in sense of the terminology of the Braun-Blanquet syntaxonomy) for the order. Family appeared to be an inadequate rank for diagnoses of alliances and suballiances. On the other hand, genus was found to be the most effective rank in differentiating the alliances and suballiances. The Lindero-Quercenion shares the same character-genera with the order Rhododendro-Quercetalia. Character genera of the suballiances Callicarpo-quercenion are Carpinus, Styrax, Smilax and Callicarpa, and those of the Pino-Quercion list Euonymus, Saussurea and Tilia.

Pinus densiflora belongs to the Pinaceae family which has been widely used for health promoting purposes as folk medicine or as a food. Various curative effects of different parts of the pine have been reported including as a remedy for carcinoma. We examined the effects of pine needle water extracts (PNE) on macrophage function using peritoneal macrophage, pre-osteoclast bone macrophage (Raw 264.7 cell) and brain macrophage (C6 microglia). When peritoneal macrophages were treated with various concentrations of PNE ($1{\sim}100{\mu}g/mL$) for 24 hours, phagocytic activity was significantly increased, whereas it had no effect on tumoricidal activity and NO production. However, the treatment of Raw 264.7 with PNE resulted in the enhancement of NO production at high concentration ($100{\mu}g/mL$). Furthermore, the treatment of C6 with PNE increased the production of NO in a concentration-dependent manner, whereas PNE suppressed NO production in $LPS/IFN-{\gamma}-stimulated$ microglia. These results suggest that PNE has differential immunomodulatory effects on macrophages.

This study was carried out in the peatland for estimating the paleoenvironment based on the analysis from its fossils plant and radiocarbon at the Hwayang-ri, Hyeondeok-myeon, Pyeongtaek-city, South Korea. Variety of fossil was collected from the peatland which could discriminated with naked eye and sorted into seeds, leaves, stems from four-stage of standard sieve. During analysis for the large plant fossil within the peatland, the dead plants were largely divided into 3 fossil zones according to its peatland. In the fossil zone III (the oldest layer; 6,970~6,070 yr $C^{14}$ B.P.), the observation of leaves of hydrophyte such as Trapa sp. and stems of Alnus japonica which appeared in wetland means that the environment was influenced by the climate changes such as rainfall increasing and sea level rise. In the fossil zone II (the middle layer; 6,070~5,800 yr C14 B.P.), the occurrence of Gramineae, Cyperaceae and Fagaceae indicate that the environmental condition might be more or less dry by decreasing rainfall and drop in sea level. The fossil zone I (the recent layer; 5,800~4,540 yr $C^{14}$ B.P.) where lots of herbaceous plants, increasing of Fagaceae, decreasing of A. japonica. and distribution of Pinaceae were showed, was inferred to be repeated both dry and wet environment due to human disturbance.
