Spring kimchi cabbage was stored fresh for 90 days in a commercial cold storage house. It was sanitized by spraying fungicide on the field before harvesting. The plastic boxes of spring kimchi cabbage were put on the pallet, covered with a 40-hole film, then stacked in the cold storage room at once. The room was maintained for 90 days at 0.7oC after cooling gradually at 2 oC/day. After 90 days, the weight loss was 4.73% and the total trimming loss was 8.26%. The weight loss was 8.08% and the net trimming loss was 3.26% after 90-day storage with partial stack cooling at 2.7oC covered with a 56-hole film. The quality of spring kimchi cabbage after 90-day storage was fresh without physiological disorders.

봄배추를 실용규모의 저장고에서 90일 간 신선하게 저장하였다. 봄배추 춘광 을 수확 1일 전에 노지에서 락스와 테 브코나졸 혼합약제를 살포하여 소독하 고 플라스틱 상자에 담에 팰릿에 적재 한 다음, 40공 타공 비닐로 씌워 저장 고에 일시에 채우고 1일 2℃씩 냉각하 여 0.7℃에서 90일간 저장한 결과 중 량감소율 4.73%, 총정선손실률 8.26%로서 총저장손실률이 12.6%였 다. 그리고 팰릿 포장한 배추를 7일간 5회 분할하여 저장고에 채우고 56공 타공 비닐로 씌워서 바로 2.7℃로 냉각 하여 90일간 저장한 결과 중량감소율 8.08%, 순정선손실률 3.26%로서 순 저장손실률은 11.1%였다. 이때 저장 한 봄배추는 생리장해가 발생하지 않 았고 90일차에도 품질이 신선하였다.

Understanding the metapopulation structure and movement of a species are required for conserving the species. In this paper, migration patterns and connectivity of patches of a threatened butterfly, Pamassius bremeri Bremer, were postulated using the mark-release-recapture (MRR) technique in a habitat located in the mid-southern region of the Korean peninsula. A total of 194 individuals were captured (137 males and 57 females) and, of them, 93 individuals (73 males and 20 females) were recaptured during the MRR experiment. The migration analysis showed 23-150% immigration and 28-53% emigration. There were high correlations between the migrating individuals and the distance between patches, but there was no correlation between migrating individuals and patch size or between migrating individuals and the number of host plants. Consequently, the migration of butterflies occurred frequently between closer patches, while patch size and quantity of the food plant had minor effects on migration behavior. Additionally, males migrated more frequently than females. Analysis of the migration patterns of P. bremeri showed that the central patch played an important role on linking patch groups and more frequent migrations were monitored between nearby patches than between the remote patches. This study suggested that active migrations take place between the neighboring multiple patches and these are accelerated if there is a stepping-stone patch between them.
