전통주 주박을 이용한 고부가가치 식품소재 개발을 위해, 상업적 시설에서 생산된 3종 약주(J-B, J-S, J-Y) 및 2종 탁주(J-H, J-W) 주박의 ethanol 추출물 및 열수 추출물을 조제하고 이들의 혈액응고 저해활성, 혈소판 응집저해 활성 및 인간 적혈구 용혈활성을 평가하였다. 5종 주박의 pH는 3.90~4.29로 유사하였으나, brix는 5.0~27.0으로 다양하게 나타났으며, 수분 및 알코올 함량에서도 시료에 따라 1.8배의 차이를 나타내었다. 주박의 색차와 성분은 첨가된 부재료 및 사용누룩에 좌우되었으며, J-W 주박의 경우 수분함량이 80.3%, brix 13, 알코올 함량 1.8%를 함유하여 다른 주박에 비해 다양한 식품제조에 용이하게 이용 가능하리라 판단되었다. Ethanol 추출효율은 J-H, J-W, J-B, J-S, J-Y의 순, 열수 추출효율은 J-S, J-B, J-W, J-H, J-Y의 순으로 높았으며, 총폴리페놀 및 총플라보노이드함량은 ethanol 추출물 중에서는 J-H, 열수 추출물 중에서는 J-Y 주박에서 가장 높았다. 5종 주박의 10종 추출물은 모두 5 mg/ml 농도까지 인간 적혈구에 대한 용혈활성이 나타나지 않았으며, J-B, J-S, J-Y의 약주 주박의 ethanol 추출물에서 유의적인 혈액응고저해 활성이 나타났으며, J-W 탁주 주박의 열수 추출물에서 thrombin 저해 활성과 J-B, J-S 및 J-H 주박 열수 추출물에서 혈액 응고인자 저해활성을 확인하였다. 혈소판 응집저해 활성평가의 경우 J-W 탁주 주박의 ethanol 및 열수 추출물에서만 아스피린에 필적하는 우수한 활성이 확인되었다. 본 연구결과는 다양한 약주 및 탁주 주박이 항혈전 활성을 가지고 있으며, 주박으로부터 항혈전제 개발이 가능함을 제시하고 있다. In this study, ethanol and hot water extracts of lees from Korean traditional wine (J-B, J-S, J-Y, J-H, and J-W) were prepared, and their effects on blood coagulation, platelet aggregation, and hemolysis of human red blood cells (hRBCs) were investigated to develop functional food ingredients from lees. The pH and brix of the lees ranged from 3.90 to 4.29 and 5.0 to 27.0o, respectively, and there was a huge difference in the water and ethanol content among the lees. The nuruk and additives used affected the color and physicochemical properties of lees. The J-W takju made from only rice and traditional nuruk, which has 13o brix and 1.8% of alcohol, has potential as functional food ingredient. With regard to the extraction yields of lees, higher yields were obtained from J-H, which contains different medicinal plants, in ethanol, followed by J-W, J-B, J-S, and J-Y. Higher extraction yields of lees were obtained from J-S in hot water, followed by J-B, J-W, J-H, and J-Y, respectively. The ethanol extract of J-H and the hot water extract of J-Y had the highest contents of total polyphenol and total flavonoids among the lees extracts. The 10 lees extracts did not show hemolysis activity against hRBCs up to 5 mg/ml. In an anticoagulation activity assay, the ethanol extracts of three yakju lees (J-B, J-S, and J-Y) and the hot water extract of J-W inhibited thrombin activity, whereas the hot water extract of J-B, J-S, and J-H inhibited blood coagulation factors. In an antiplatelet aggregation activity assay, only the J-W takju lees showed significant inhibition activity. Our results suggest that lees from traditional wine had high potential as a novel antithrombosis agent.

Radish (Raphanus sativus) is a common cruciferous vegetable, and its aerial parts, called Mu-chung in Korean, have plentiful nutritional components such as vitamins, minerals and dietary fibers. Mu-chung has been used as a kimchi, a traditional Korean fermented dish, and dried Mu-chung is an important component of soups commonly consumed during winter in Korea. Since the advent of the mass production of radish in Korea, with the segregation of farm areas and towns and changing diets, Mu-chung has mostly been discarded instead of utilized. In addition, studies concerning the efficient utilization and useful bioactivities of Mu-chung are still lacking worldwide. In this study, we prepared the ethanol extract of Mu-chung and its subsequent solvent fractions. Antimicrobial, antioxidation, and anticoagulation activities were then evaluated in the hopes of developing a functional biomaterial from Korean radishes` aerial parts. The ethanol extraction yield for hot-air dried Mu-chung was 5.6%, and the fraction yields of n-hexane (H), ethylacetate (EA), butanol (B) and water residue were 25.3, 3.6, 19.4, and 51.7%, respectively. Analysis of total polyphenol and total flavonoid contents showed that the EA fraction had the highest content (97.57 and 152.91 mg/g) amongst the fractions. In antimicrobial activity assays, the H and EA fractions were effective against gram positive bacteria (Staphylococcus aureus, Listeria monocytogenes, and Bacillus subtilis), but not effective against gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa). The B fraction also exhibited moderate antibacterial activity, suggesting that the extract of Mu-chung has various antibacterial components. In antioxidation activity assays, the EA fraction showed strong DPPH, ABTS and nitrite scavenging activities (69-222 μg/ml of IC50), including reducing power. In anticoagulation activity assays, the EA fraction demonstrated strong inhibition activity against human thrombin and prothrombin. Prominent anticoagulation activity was found in aPTT assays; the aPTT of the EA fraction was extended 15-fold compared than that of the solvent control. Our results suggest that Mu-chung is an attractive nutritional food material possessing useful bioactivities, and the EA fraction of Mu-chung could be developed as a functional food ingredient.

In this study, the antioxidant activities and cytoprotective effects against oxidative stress of Lonicera japonica Thunb. 50% ethanol extract and ethyl acetate fraction were investigated. Using the 1,1-diphenyl- 2-picrylhydrazyl assay, the free radical scavenging activity (FSC50) of L. japonica Thunb. 50% ethanol extract and ethyl acetate fraction was determined as 152.00 and 77.25 μg/ml, respectively. To measure the reactive oxygen species (ROS) scavenging activity, the total antioxidant capacity (OSC50) was determined by using a luminol-dependent chemiluminescence assay. The antioxidant activity of the ethyl acetate fraction (0.33 μg/ml) was approximately four times stronger than that of the 50% ethanol extract (1.12 μg/ml). The protective effect against <sup>1</sup>O<sub>2</sub>-induced cellular damage of human erythrocytes (τ<sub>50</sub>) was 46.0 min at 10 μg/ml of the 50% ethanol extract and 52.3 min at 1 μg/ml of the ethyl acetate fraction. We also investigated the cytoprotective effects against oxidative stress induced by H<sub>2</sub>O<sub>2</sub> and the intracellular ROS scavenging activity in response to UVB irradiation and found that the extract and fraction protected human skin cells from damage and reduced ROS. These results confirmed that L. japonica Thunb. was a valuable plant-derived natural antioxidant with potential for development as an antioxidative functional ingredient.

코로나19로 팬데믹이 초래되자, 사회 전반이 변화하고 있으며 ‘학교’ 또한 변화하고 있다. 다른 무엇보다 학생의 ‘안전’을 최우선으로 하기에 등교를 미루어야 한다는 입장과 더불어 학교 수업을 재개하여 학생의 ‘학습권’을 보장해야 한다는 상반된 요구 속에서 교육부는 학생의 ‘안전’을 보호하면서도 ‘학습권’을 보장하기 위해 사상 초유의 온라인 개학을 실시하였다. 이처럼 코로나19로 인해 학교는 ‘안전(방역)’, ‘학습’, ‘사회성 함양’, ‘돌봄’ 등 다양한 역할을 수행하는 가운데 변화를 일상화하고 있다. 본 연구는 코로나19로 인한 학교 교육의 변화 속에서 교원들이 경험하는 패러독스 현상을 분석하기 위해 수도권 소재 초등학교 교원들을 대상으로 면담을 진행하는 등 질적연구를 수행하였다. 본 연구 결과를 살펴보면 다음과 같다. 첫째, 코로나19 이후 학교 현장에서는 하나의 현실에 대해 ‘상호 배타적인 해석들이 공존하고, 그 어느 것도 진실이 아니라 말하기 힘든’ 패러독스 현상들이 발생하고 있었다. 둘째, 코로나19로 인한 학교 교육에서의 패러독스 현상은 코로나19가 학교 교육의 ‘위기’임과 동시에 ‘기회’로 작용할 수 있음을 보여 주었다. 이러한 연구 결과를 바탕으로 시대적·사회적 변화에 부응하면서도, 포스트 코로나 시대 학교 교육이 나아가야 할 방향과 이를 지원하기 위한 교육정책에 대한 시사점을 제시하였다. As the pandemic caused by Covid 19, the whole society was changing, and schools were no exception. There was a confrontation between the argument that school should be postponed the new school year by putting students safety first and the argument that students right to study should be guaranteed by reopening the school. Accordingly, Korean Ministry of Education decided to resume classes online, marking the first time all schools across the country were taking part in remote learning in order to protect the “safety” of students while ensuring their “right to learn”. As such, due to Covid 19, schools are making changes in everyday life while playing various roles such as “safety(prevention)”, “learning”, “cultivating sociality”, and “caring”. This study conducted a qualitative study, such as conducting interviews with elementary school teachers in the metropolitan area to analyze paradoxes experienced by teachers amid the change in school education caused by Covid 19. The results of this study are as follows. First, after Covid 19, paradoxes have occurred in schools. In the school, there were phenomena in which mutually exclusive interpretations coexisted, which was hard to say that none of them were true. Second, the paradoxes in school education caused by Covid 19 showed that Covid 19 can act as both a “crisis” and an “opportunity” in school education. Based on these findings, in response to the social changes of the times, the direction for school education in the post-covid era and implications for education policies are presented.

Background: In cerebral palsy (CP), parents’ quality of life and rearing attitude are considered possible factors that influence patients’ quality of life, function level, and performance in daily activities. Despite these facts, little attention has been given to demonstrate a relation between these factors. Objects: This study aimed to demonstrate the relationship between parents’ quality of life, functional level, and performance in daily activities, the quality of life of school-aged children with spastic CP. Methods: This study included 24 parents of school-aged children with spastic CP. The KIDSCREEN-52 and World Health Organization quality of life (WHOQOL)-BREF questionnaires (including physical, psychological, social, and environmental domains) were used as research tools to assess the quality-of-life profiles of the children with spastic CP and those of their parents, respectively. In addition, the function levels and performance in daily activities of the children with CP were assessed by using the gross motor function measure (GMFM) and modified Barthel index (MBI). Correlation and multiple regression analyses were performed to clarify the determinants of the quality of life of the children with CP. Results: The KIDSCREEN-52 score correlated with the total score (r=.735, p<.01) and all domains of the WHOQOL-BREF questionnaire (physical: r=.542, p<.01; psychological: r=.690, p<.01; social: r=.568, p<.01; and environmental: r=.783, p<.01). In addition, significant correlation was found between the KIDSCREEN-52 and MBI scores (r=.411, p<.05), and between the MBI and GMFM scores (r=.427, p<.05). After controlling for age, gender, paralytic type, GMFM, and MBI, the WHOQOL-BREF score (R2=.621), particularly in the environmental domain (R2=.699), remained independently related to the quality of life of the children. Conclusion: These findings suggest that the quality of life of school-aged children with spastic CP can be influenced by the quality of life of their parents. This study provides useful information for future studies to investigate the quality of life of children with CP.

양송이는 우리나라의 대표적인 식용버섯으로 국내 버섯 총생산량의 7.1%인 10.6천 톤이 생산되었다(MFAFF, 2017). 배지는 양송이 생육에 필요한 각종 영양분과 수분을 제공하고 있으며, 버섯의 생산량에 결정적인 영향을 미친다. 현재 국내에서는 2·3차 배지제조를 버섯 재배사에서 수행하므로 재배사의 회전율이 낮으며, 양송이의 안정적인 생산이 어렵다. 고품질의 양송이 생산을 위하여 국내실정에 맞는 소형터널시스템 개발이 필요하다. 본 연구에서는 midas Gen 프로그램을 활용하여 양송이 배지 발효용 소형터널시스템의 지지대 및 바닥 격자판을 설계하였다. 소형터널시스템의 규격은 40 ft 컨테이너로 12.057*2.352*2.282m이다. 지지대는 규격(L*W*H) 12*2.4*0.8 m (4칸)로 모델링하였으며, 분포하중이 5.81 kN/m, 재질 SS41일 때 지지대를 구성하는 H빔의 규격을 변경하며 해석을 진행하였다. 바닥 격자판은 지지대의 한 칸에 해당하는 부분만 모델링하여 해석을 진행하였으며 규격(L*W)은 3*2.2 m (4*3칸), 분포하중은 1.81 kN/m이고, 재질은 SS41과 SUS304 두 가지를 비교하였으며 격자판을 구성하는 사각파이프의 규격을 변경하며 해석을 진행하였다. 지지대와 바닥 격자판의 허용 처짐량은 연속거더의 처짐 허용값 L/2,000(지간 L≤10 m)를 통해 각각 0.15 cm, 0.0375 cm 이며, 재질의 허용응력은 SS41 13.734 kN/cm2, SUS304 5.3 kN/cm2이다. 지지대의 해석결과 H빔 규격(H*B*tw*tf)이 14.8*10*0.6*0.9 cm 일 때 최대 처짐량이 0.113 cm(< 0.15 cm), 최대응력이 9.494 kN/cm2 (< 13.734 kN/cm2)이므로 적합하다고 판단하였다. 바닥 격자판의 해석결과 재질에 따른 최대 처짐량및 최대 응력값은 큰 차이를 보이지는 않았으나 SS41이 좀 더 작은 값으로 나타났으며, 재질이 SS41이고 사각파이프의 규격(H*B*t)이 12.5*7.5*0.6 cm 일 때 최대 처짐량이 0.036 cm (< 0.0375 cm), 최대응력이 2.841 kN/cm2 (< 5.3 kN/cm2)이므로 적합하다고 판단하였다.
