  • Many Safety training up to now has been done at site varying with their condition without any standardization or fundamental work related technique. In order to prevent any accidents from construction site, now as we all know, we have to approach on it with work based method. The authors have investigated a couple of construction site for collecting the ideas from site Engineers of this. Some of ideas analyzed with the above related data have been shown as conclusions.

  • In this paper, we studied a now VDSL frequency plan mode 6 for improved\ulcorner symmetric 10MDSL service. The frequency plan 998 for asymmetric and frequency plan 997 for symmetric have arc not optimally designed for 10MDSL service. To improve reach and rates of 10MDSL, we proposed for a now frequency plan. According to the results of our simulation studios of newly Proposed mode 6 frequency plan which compared to plan 998, 997, and ethers[2], the new scheme gives an improved performance in rates and reach.

  • 최근의 Network Of Workstations (NOW) 시스템은 범용의 컴퓨팅 플랫폼으로 각광을 받고 있지만, 그 활용률은 여전히 사용자의 기대에 미치지 못하고 있다. 본 논문에서는 NOW 시스템의 활용률을 높이기 위한 방법으로 시스템의 부하 수준을 고려하여 프로세스 재 순서 (process reordering)를 사용하는 동시 스케쥴링 기법인 PROC (Process Reordering-based Coscheduling)을 제안한다. 그리고 자세한 시뮬레이션을 통해 PROC의 우수성을 검증한다.

  • Lampteromyces japonicus is the most popular source of mushroom poisoning in Japan. We isolated poisonous substance, illudin S, 40 years ago, which shower strong anti-tumoric activity. Its analogs are now the most hopeful anti-cancer agent. Clitocybe acromelalgia gives unique poisoning which exhibits symptoms similar to acromelalgia and erythromelalgia. We intended to isolate the toxin causing these poisoning but neuroexciatory compounds, acromelic acids A and B, were isolated. They are now known as the most potent glutamate agonists and good reagents for the study of the glutamate receptor of a neurocell.
