Feasibility of Ivy (Hedra helix) for landscaping in Seoul, Korea

Due to the global warming, Seoul in Korea seems to be plausible to grow evergreen broad-leaved trees over the cold winter. This offers the planting options to create green environment. Thus, it became worth investigating what kinds of evergreen broad-leaved plants could stand in Seoul during the winter. Ivy (Hedera helix) has been chosen in the current study which is a well-known native and ornamental plant in Europe. It grows in warm condition in general. The current study tracked H. helix which is evergreen cover plant over winter in order to evaluate the possibility for utilizing this species as a climber or cover-plant in Seoul. We found that H. helix can survive over the winter and can be utilized to create evergreen environment in Seoul. It also implies that similar kinds of plants could be tested assuming the environment of Seoul is becoming more suitable for the plants originated from the warmer sites. H. helix is an option for elaborating outdoor environments in the city that lacks of green color

EFFECTS OF THREE PREPARATORY MOVEMENTS ON SIDEWARD PROPULSIVE MOVEMENT

This study investigated the effects of three preparatory movements (squat, countermovement and hopping) on the sideward propulsive movement. Seven subjects were analyzed in 3-D to determine how fast they reacted to external signals, using three techniques, to reacl1 an aIming spot. The hopping and the countermovement types were considered better than the squat type in the propulsion. The hopping particularly showed the shortest duration from the external signal to take-off and also recorded high extension moments due to the pre-stretch mechanism for the push-off phase

Non-Invasive Follow-up Evaluation of Post-Embolized AVM with Time-Resolved MRA: A Case Report

We report the hemodynamic assessment in a patient with cerebral arteriovenous malformation using time-resolved magnetic resonance angiography (TR-MRA), a non-invasive modality, and catheter-based digital subtraction angiography (DSA), before and after embolization. Comparison of the results showed that TR-MRA produced very fast dynamic images and the findings closely matched those obtained at DSA. For initial work-up and follow-up studies in patients with vascular lesions, TR-MRA and DSA are therefore comparable
