The bacterial diversity of an Antarctic hard coral, Errina fissurata, was examined by isolating bacterial colonies from crushed coral tissue and by sequencing their 16S rRNA gene. From the analyzed results, the bacteria were classified as Actinobacteria (56%), Firmicutes (35%) and Proteobacteria (9%). The thirty-four isolates were cultured in liquid media at different temperatures and their growth was assessed over time. The majority of the isolates displayed their highest growth rate at 25℃ during the first three days of cultivation, even though the coral was from a cold environment. Nevertheless, strains showing their highest growth rate at low temperatures (15℃ and 4℃) were also found. This study reports the composition of an Antarctic hard coral-associated culturable bacterial community and their growth behavior at different temperatures.

본 논문은 rotation of subspaces 개념을 이용한 도래각 추정 방법을 제시한다. 이 방법은 여러 응용분야에서 대두되는 부공간들(subspaces)의 각도 및 거리와 밀접한 관련이 있다. 먼저 최소 자승을 이용하여 한 부공간을 다른 부공간으로 변환 시켜주는 최적 변환 행렬을 구하기 위한 효율적인 방법을 유도하고 이를 이용하여 다중 광대역 신호들 (인코히어런트, 부분적인 코히어런트와 완전한 코히어런트의 혼합신호들)의 도래각을 추정한다. 대표적인 응용으로, 잡음의 배열 스펙트럼 밀도 행렬이 변하지 않는 액티브 시스템(e. g. sonar system) 경우에 성능을 높이기 위하여 효율적인 ROSS (rotation of signal subspaces) 알고리듬을 제안한다. ROSS 알고리듬은 Wang-Kaveh's CSS-focusing 방법에서 사용하는 예비처리와 공간 필터링을 필요로 하지 않는 장점이 있으며 일반적인 모든 배열 안테나에도 적용될 수 있다. 시뮬레이션 결과, 제안된 새로운 알고리듬이 CSS-focusing 방법 및 Forward-Backward Spatial Smoothed MUSIC 보다 높은 성능을 가짐을 알 수 있었다.

Objective: The aim of this study was to compare the quality characteristics of retorted Samgyetang (Korean ginseng chicken soup) made from white semi-broilers (WSB; Ross×Hyline white, 3 weeks old), commercial broilers (CB; Ross, 4 weeks old), Korean native chickens (KNC; Hanhyup-3-ho, 12 weeks old) and old laying hens (OLH; Hyline white, 72 weeks old) and to explore the possibility of using the carcasses of KNCs and OLHs as raw material for product diversification. Methods: Raw and cooked meat quality, fatty acid composition and consumer acceptance were analyzed. Results: Among the chicken breeds, OLH and KNC showed a higher shear force value than WSB and CB due to high insoluble collagen contents. However, the meat of KNC was more tender than that of OLH. The meat of OLH was characterized by the lowest moisture content and highest crude fat content. The meat of KNC was characterized by a higher proportion of saturated fatty acids, α-linolenic acid and arachidonic acid than that of OLH. The meat of OLH showed the highest content of unsaturated fatty acid, particularly linoleic acid, in its thigh meat. Electronic nose readings revealed that the meat aroma pattern was clearly different across breeds. OLH had the lowest overall acceptance score, while no differences were found in flavor, texture, juiciness and appearance among WSB, CB, and KNC. Conclusion: KNC shows potential as raw material for Samgyetang, while additional preprocessing methods, such as tenderization and fat removal, are required for the utilization of OLH as raw material for retorted Samgyetang.
