This study examined growth and sensory characteristics of soybean sprout cultured at $25\pm1^{\circ}C$ for 4 days with distilled water(control) and green tea extract(0.03 and $0.05\%$). Initial germination rate was higher when soaking in green-tea extract than in the control. The proper concentration of green-tea extract was $0.03\%$. The growth of soybean sprout in $0.05\%$ green-tea extract was better than the control for the hypocotyl thickness and mot hair. Soybean sprout grown with green-tea extract were better than that with control inappearance, flavor, texture and over-all acceptabilitty.

This study examined the growth and sensory characteristics of soybean sprout cultured at 25$\pm$1$^{\circ}C$ for 4 days with distilled water control and green tea extracted water (0.03% and 0.05%). The proximate composition of soybean sprout in the green-tea water was better than that of the control in ash, protein and fat, while the soybean sprout was especially higher in 0.05% green-tea water. The contents of vitamin C and $\beta$-carotene were higher in soybean sprout in green-tea water than the control. The total free amino acids composition of soybean sprout in green-tea water was better than that of the control, with the highest being obtained in soybean sprout in 0.03% green-tea water. Antioxidative activity was assayed by DPPH radical scavenging ability with spectrophotometer at 514 nm. The soybean sprout in green-tea water was higher than control. The amylase activity of the soybean sprout increased steadily during the first 4 days and that of the control was higher than soybean sprout in green-tea water. The proteinase of soybean sprout steadily increased during 4 day culture. Furthermore, the proteinase activity of soybean sprout in green-tea water was higher than that of the control up to 2 days. Whereas after 3 days, it was the highest in 0.03% green-tea water and then decreased remarkably in 0.05% green-tea water.

Osteoporosis is a disease that often occurs in postmenopausal women. The purpose of this study was to examine the positive effects of Cheongukjang powder containing menaquinone-7 (MK-7) on bone health circulation in postmenopausal women. Fifty-six postmenopausal women were recruited into a randomised double-blind placebo-controlled trial. The participants were randomly assigned into two groups. For 12 weeks, one group received $800{\mu}g$ MK-7 in the form of Cheongukjang packs (CMK-7), and the other group received the same amount of identical-looking placebo packs containing barley meal for 12 weeks. Femoral bone mineral density (BMD), bone-specific alkaline phosphatase (ALP), deoxypyridinoline (DPD), osteocalcin (OSC), serum Ca, and serum P were measured at baseline (0 weeks) and 12 weeks. After 12 weeks in the CMK-7 group, it was found that BMD, serum Ca, and serum P had increased above the baseline (p<0.0001, p=0.0028, p<0.0001), whereas bone-specific ALP, DPD, and OSC had decreased below the baseline (p=0.0003, p<0.0001, p<0.0001). Therefore, MK-7 taken as Cheongukjang is expected to prevent osteoporosis in postmenopausal women.

본 연구에서는 통합형 직업교육 거점학교 담당 특수교사들의 거점학교 운영에 대한 인식을 질적 연구를 통하여 포괄적으로 분석함으로써 향후 거점학교의 운영 내실화를 위한 시사점을 제공하고자 하였다. 9명의 거점학교 운영 담당 특수교사와의 면담 자료를 Van Kaam의 현상학적 분석 방법에 따라 분석한 결과, 27개의 부주제, 9개의 주제, 성과요인과 과제요인이라는 2개의 범주로 분류되었으며, 거점학교 특수교사들은 성과요인보다 과제요인을 더 많이 인식하고 있는 것으로 나타났다. 첫 번째 범주인 성과요인으로는 거점학교 운영을 통해 특수학급 교사, 학부모, 유관기관 등의 관계자 및 관계기관과의 연계가 강화되었고, 거점학교 참여 특수학급 학생들과 교사들이 높은 만족도를 나타낼 뿐만 아니라 이들의 진로와 취업에 대한 인식이 적극적으로 변화되었으며, 적절한 진로직업교육 기회의 확대와 취업률 제고를 이룬 점을 들고 있었다. 두 번째 범주인 과제요인으로는 인력부족으로 대표되는 거점학교 업무환경의 개선 필요성, 성과 위주의 거점학교 정책에 대한 지적, 관리자·학부모·지역사회 등의 장애인식개선의 필요성, 유관기관과의 연계·협력, 현장실습, 거점학교 특성화 등을 강화하는 방향으로의 거점학교 정체성에 대한 재고 필요성, 교육청 등의 상급기관과 교내에서의 행정적 지원의 필요성이 제기되었다. 이러한 연구결과를 토대로 본 연구에서는 향후 거점학교 운영 내실화를 위해 필요한 과제들을 제시하였다. The purpose of this study was to provide implications to stabilize the future management of job-centered schools by the comprehensive analysis on the perceptions of special education teachers who manage job-centered schools based on a qualitative study. The data obtained from the interviews with 9 special education teachers who manage job-centered schools were analyzed using the phenomenological analysis method of Van Kaam. As the results, the data were segmented into 27 sub-themes, 9 themes, and 2 categories of achievement and challenge factors. The special education teachers were found to perceive challenge factors more strongly than achievement factors. As the first category of achievement factors, they pointed out that the management of job-centered schools strengthened the connection among the related individuals and organizations including special class teachers, parents of the students with disabilities, and the related organizations, produced high levels of satisfaction among special class students and teachers participating in the job-centered schools, changed their perception of future directions and employment in an active manner, and expanded the opportunities for proper career and vocational education and increased employment rates. As the second category of challenge factors, they included the needs to improve the working environment of the job-centered schools characterized by the lack of human resources, criticism of the policies of the job-centered schools, which were without long-term and systematic approaches and focused on quantitative outcomes, the needs of improving the awareness of a disability of administrators, parents of students with disabilities, and local communities, reconsideration on the identity of the job-centered schools in the direction of strengthening connection and cooperation with the related organizations, field training, and the differentiation of the job-centered schools, and the needs of providing administrative support by high-level organizations such as the Office of Education and schools. Based on the results, this study suggested the tasks necessary for stabilizing the future management of the job-centered schools.

The purpose of this study is to find out the optimal mixing ratios of Mal-Cha for the preparation of Jeung-Pyun through sensory and mechanical tests. The proximate composition of Mal-Cha were $5.46\pm0.15\%$ of moisture, $4.43\pm0.11\%$ of total nitrogen, $7.52\pm0.21\%$ of crude lipid, $8.74\%$ of crude fiber, $8.51\pm0.09\%$ of ash. Overall quality of Jeung-Pyun with $1.5\%$ Mal-Cha was the worst compare with 0, 0.5 and $1.0\%$ ones(p<0.05). Especially, $1.0\%$ Mal-Cha Jeung-Pyun showed the best overall quality. But the sweetness, sourness, flavor, hardness, and moistnes were not significantly different among all the treatments. Acceptabilities of 0.5 and $1.0\%$ Mal-Cha Jeung-Pyuns were not significantly different from that of the control in their sensory and mechanical qualities. Total color difference increased with the amount of Mal-Cha significantly(p<0.001).

본 연구에서는 참기름 제조과정의 부산물인 참깨탈지박을 고초균으로 발효하여 이를 총 리그난 함량 및 항산화활성을 평가한 후 최종 균주를 선발하였고, 참깨탈지박 발효 추출물의 기능성을 확보하고자 하였다. 국내의 전통발효식품으로부터 분리 균주 중 β-glucosidase 활성을 보유한 고초균 15종을 이용하여 참깨탈지박에 37℃에서 24시간 발효하였다. 참깨탈지박 발효 전과 발효 후의 β-glucosidase 정량, 총 리그난 함량, 총폴리페놀 함량, 총플라보노이드 함량 그리고 DPPH 라디칼 소거능을 분석하였다. β-glucosidase 활성 측정 결과, SRCM103716 발효 추출물에서 16.88 unit/l의 높은 활성을 보였다. 총 리그난 함량은 BCH3678, BCH3572 발효 추출물에서 각각 약 1613.8 mg/l, 1599.5 mg/l으로 가장 높았다. BCH3623, BCH3558, SRCM103716 발효 추출물에서 각각 1534.9 mg/l, 1528.2 mg/l, 1521.8 mg/l로 두번째로 높게 나타났다. 총 폴리페놀 함량은 SRCM103716 발효 추출물이 2803.3 mg/l로 가장 높게 나타났고, 총 플라보노이드 함량은 SRCM103716, BCH3678의 2종이 각각 1553.1 mg/l, 1488.7 mg/l로 가장 높게 증가되었다. DPPH 라디칼 소거능을 확인 한 결과, SRCM103716 발효 추출물에서 약 66.5%로 가장 높게 증가하였다. 이에 최종적으로 B. subtilis SRCM103716를 참깨탈지박 발효균주로 선발하였다. 이들 결과를 바탕으로 리그난 및 각종 항산화 성분 등의 기능성 성분을 함유하는 발효 참깨탈지박을 확보하여 추후 장류 소재로 이용하고자 하였다. This study was conducted to investigate the total lignin content and anti-oxidant activity in extracts of defatted sesame seeds (DSS) fermented with 15 strains of Bacillus subtilis. The anti-oxidant activities of DSS were analyzed both before and after fermentation. The total lignan content of the DSS extracts fermented with BCH3678 (1,613.8 mg/l) and BCH3572 (1,599.5 mg/l) were relatively high compared to other strains. Anti-oxidant activity was determined according to phenolic compound and flavonoid content and DPPH radical scavenging rate; the highest total phenolic compound content was provided by the DSS with SRCM103716 at 2,803.3 mg GAE/g which returned total flavonoid content of 1,553.1 mg/g as strong correlation of its anti-oxidant activity. The DSS extract fermented by SRCM103716 at 37℃ for 24 hr showed the highest DPPH scavenging rate at 66.5%. The fermented DSS extracts, regardless of strain, demonstrated higher anti-oxidative activity than the unfermented control, and these results suggest that such extracts could be useful as a potential source of bioactive compounds.
