  • This study examined the stainability and functionality of cotton dyed with the extract of Salvia Plebia R. Br. as a research preceding the development of health functional materials and fashion products with a healing motif. The CIELAB measurements of the cotton fabric dyed with the extract of Salvia Plebia R. Br. showed 73.32 for $L^*$, 1.7 for $a^*$, and 37.78 for $b^*$, while the Munsell measurements exhibited 2.63Y in color, 7.18 of brightness, and 5.49 of chroma. The degree of staining resulting from color fastness to laundering, and that resulting from color fastness to perspiration (acid and alkaline), as well as the level of color fastness to crocking (wet and dry) all stayed between relatively higher levels of 4 and 5. The fabric dyed also exhibited SPF 50+, an outstanding sun blocking performance. The deodorization rate was also excellent, rising from 97% to over 99% when the time elapsed increased from 30 minutes to 120 minutes. The fabric dyed also showed a 99.6% antimicrobial activity against staphylococcus aureus ATCC 6538, and a 71.4% antimicrobial activity against Klebsiella pneumoniae ATCC 4352. The aforementioned findings indicate that fabrics dyed with the extract of Salvia Plebia R. Br. contain the potential to be developed for use as health-related materials and fashion products that promote healing.

  • 본 연구는 무지개송어 양식 산업의 생산성 향상을 위해 전 암컷 무지개송어 대량생산을 위한 일환으로 성호르몬에 의한 생리학적 성전환과 자성발생 2배체어를 유도하였다. 생리학적으로 성전환된 수컷을 만들기 위하여 부화 후 첫 먹이를 먹는 시기에 웅성호르몬인 17 alpha-methyltestosterone (MT) 5 mg을 사료에 흡착시켜 사육수온 $13^{\circ}C$에서 적산수온 $800^{\circ}C$까지 처리한 결과 96.7%의 수컷 유도율을 보였다. 또한 정상 수컷 정액을 이용하여 수정 10분 후 $28^{\circ}C$에서 20분간 고온 처리하여 61.7%의 자성발생 2배체가 유도되었다.
