회전기 고정자권선 절연물은 전기적, 기계적, 열적, 환경적 열화요인이 단독 또는 복합적으로 작용하여 열화된다. 본 논문에서는 실제 산업현장에서 운영중인 고전압 전동기의 운영환경을 조사하여 건조환경에서 운영중인 전동기와 다습환경에서 운영중인 전동기에 대하여 절연진단시험을 실시하고 각 시험에서 도출된 절연진단인자를 비교하여 환경적 열화요인이 우세한 운영환경에 따른 절연물의 특성변화를 분석하였다.

In 2010, symptoms of leaf and stem rot were observed on potted plants (Peperomia quadrangularis) in a greenhouse in Yongin, Korea. The causative pathogen was identified as Myrothecium roridum based on morphological data, internal transcribed spacer sequence analysis, and pathogenicity test. To our knowledge, this is the first report of M. roridum causing leaf and stem rot disease on P. quadrangularis in Korea and elsewhere worldwide.

An experiment and simulation were performed for hydrogen separation of mixtures by PSA (pressure swing adsorption) process on activated carbon. The binary ($H_2/Ar$; 80％/ 20％) and ternary ($H_2/Ar/CH_4$; 60％/ 20％/ 20％) mixtures were used to study the effects of feed composition. The cyclic performances such as purity, recovery, and productivity of 2bed-6step PSA process were experimentally and theoretically compared under non-isothermal and non-adiabatic conditions. The develped process produced the hydrogen with 99％ purity and 75％ recovery from both processes. Therefore, optimal separation condition was referred multicomponent gas mixtures.
