본 연구는 붉은꽃인동덩굴의 적심높이(60, 120, 180 cm) 가 가지길이, 측지수 및 피복에 미치는 적심높이별 영 향을 알아 보기 위하여 수행하였다. 인동덩굴의 줄기길 이는 고절위(180 cm) 적심이 저절위(60 cm) 적심보다 길 었고, 측지수는 저절위 적심이 고절위 적심보다 많았다. 그러나 분지수는 적심처리간에 큰 차이가 없었다. 퍼골라 벽면의 피복도는 저절위 적심이 85%, 중절위 적심이 74%, 고절위 적심이 62%를 보였다. 개화는 5월 중순부터 10월 중순까지 계속되었고, 첫 개화는 60 cm 적심이 5월 중순으로 가장 빨랐다. 대체로 적심 높이가 낮고 적심시기가 빠를수록 개화가 빨랐고, 개화최성기는 8월 중순이었다. 붉은꽃인동덩굴을 이용한 퍼골라 벽면의 가로 3.0 m ×높이 2.2 m 녹화를 하기 위해서는 퍼골 라당 6주(1m당 2주)를 재식하고, 60 cm 벽면 높이에서 1회 적심하면 당년에 85%의 벽면스크린 및 녹화가 가 능하였다.

Background : This study aimed to identify the mechanisms of the antinociceptive effects of PG in the fibromyalgia (FM)-like animal model. Methods and Results : To assess the possible effect of PG on FM symptoms, we constructed a FM animal model induced by intermittent cold stress with slight modification. All mice underwent nociceptive assays using electronic von Frey anesthesiometer and Hargreaves equipment. To assess the relation between PG and the expression levels of brain-derived neurotrophic factor (BDNF), cAMP response element-binding protein (CREB), and phosphorylated CREB (p-CREB), western blotting and immunohistochemistry analyses were performed. In behavioral analysis, nociception tests showed that the pain threshold was significantly decreased in the FM group compared to control group. Western blot and immunohistochemical analyses of the medial prefrontal cortex and hippocampus showed downregulation of BDNF and p-CREB proteins in the FM group compared to control group. PG recovered these changes at behavioral tests and protein level. These results provide evidence that the effects of PG extract in the FM model may be related to its modulating effect on the BDNF signaling pathway in the hippocampus and medial prefrontal cortex. Conclusion : Our animal model may be involved in the mechanism by which PG extract is effective as a therapeutic agent for FM.

Disasters make huge debris in short period of time. In spite of increasing risk of disasters by recent climate change, consideration on disaster debris is still insignificant in Korea. In order to improve management of disaster debris, disaster debris management guidelines have been compared with those of United States and Japan. According to comparison, debris management of Korea showed lack of concreteness for field workers. The unit recovery costs of inland debris and offshore debris were 173 and 318 thousand won per ton, respectively. Inland debris was mainly affected by quantity and location. And offshore debris were affected by finances.

Understanding the host defense mechanisms in response to brown leaf spot disease caused by Cochliobolus miyabeanus is very important for production of resistant plant. In this study, two-dimensional gel electrophoresis (2-DGE) in conjunction with mass spectrometry was utilized to unravel changes of stress inducible proteins in rice leaves infected with C. miyabeanus. For this purpose, we firstly observed disease developmental process of C. miyabeanus in rice using trypan blue, anilin blue, acid fuchsin staining, and DAB staining for ROS detection and expressional abundance of ROS related proteins in rice leaves inoculated was confirmed by Western blotting. Proteins were extracted by PEG fractionation and their expression patterns were analyzed by 2-DGE and subjected to image analysis using the ImageMaster 6.0 2D Platinum software, resulting in the identification of 86 differentially expressed protein spots with significantly changes (p<0.05) compared with control. MALDI-TOFTOF-MS analysis revealed that 69 proteins including 42 and 27 significantly up- and down-regulated proteins, respectively, were identified. Based on gene ontology analysis, identified proteins were classified according to their functional groups: metabolism (20%), oxygen-detoxifying (13%), protein stress/defense (24%). Thus, these results for the first time suggest that differentially induced proteins may play a key role for understanding host defense mechanisms during rice -C. miyabeanus interaction.

A cross was made in 1995 between Cymbidium “Tropical Yellow”, a brownish yellow colored petal and medium plant sized variety, and “Lucky Rainbow Rapin Hot”, a light purple-pink petal with red lip and medium sized variety. A cross was made in 1995 between Cymbidium “Tropical Yellow”, a brownish yellow colored petal and medium plant sized variety, and “Lucky Rainbow Lapin Hot”, a light purple-pink petal with red lip and medium sized variety. The eighty seven progenies were obtained after planting and acclimatization in green house.
