As one of the post-COVID-19 response strategies, representative processed products derived from the natural plant material flaxseed and a dietary supplement fortified with female hormones (estrogens) were developed in Canada, an eco-friendly country was introduced. These products were: 1) flaxseed oil to help maintain cognitive and immune function, 2) Lignan50, a substance with effects similar to estrogen, a female hormone, 3) XanFlax, a thickener for confectionery/baking and egg substitute, 4) MediFlax, a constipation reliever, 5) SesaFlax, which has a fragrance similar to sesame, 6) Linusorb, which is effective for its pharmaceutical anti-inflammatory/anti-oxidation and anti-aging properties, and 7) LinuLyte, a water/electrolyte supplement containing high dietary fiber. It is expected that these dietary products will help maintain and promote health as part of a response to the COVID-19 pandemic.

The purpose of this study is to understand general safety of school buses and safety education at early childhood education center, analyze teachers' awareness and needs for safety of a school bus, and present fundamental data for teachers to protect young children against possible incidents at a early childhood education center. To grasp the conditions of safety of a school bus, safety education, and teacher's awareness and needs for the bus, a survey was conducted with 171 teaches who got on a school bus to bring in and out young children at kindergartens and child care center in Seoul area. The results of this study were as follows: First, as for safety of a school bus at early childhood education centers, young children used a school bus to attend a center and many buses had 15 to 25 seats at most early childhood education centers (70.3%). In terms of school buses, they were good at being insured, yellow vehicles, emergency network, and teachers' boarding but were poor at children protection mark attachment, observance of the seating capacity, and wearing a safety belt. Only about a half (54.4%) were registered as children protection vehicles; thus, young children could hardly be protected by the children protection vehicles. After investigating home-coming guidance for young children using a school bus at an educational center, teachers led young children to parents in most cases, while parents came out to send and meet them in a half of the cases; therefore, parents are required to change their perception of young children's safety. It was found to take about one hour a day on average for teachers to get on a school bus to young children. Second, in terms of safety training for a school bus at early childhood education centers, most centers (60.8%) provided parents about once or twice a year with information on the use of school buses in the form of newsletter. While young children's safety training for a school bus provided during regular classes and in need of safety guide for attending the center, there were difficulties due to the lack of educational materials related to safety training for a school bus and the want of concerns by the centers. Third, as for teachers' awareness and needs for safety of a school bus, teachers thought of a school bus as the center as relatively safe; however, nearly a half of the teachers failed to know the provision of children protection vehicles and penalties.

청각으로부터 분리한 다당류의 혈액응고 저해기작 및 in vivo 항응고 활성

청각에서 분리된 항응고 다당류의 혈액응고 저해기작을 검토하였다. 항응고성 다당 획분(CF-30-Ⅳ-ⅱ, CF-30-Ⅳ)은 내인성 경로와 공통 경로에서 농도 의존적으로 작용한다. 항응고획분(CF-30-Ⅳ-ⅱ)은 내인성 경로의 factor asaay시 lupus anticoagulant 항체의 활성에 영향을 주지 않았으나 응고과정 중 factor Ⅷ, Ⅸ, ⅩⅠ, ⅩⅡ의 활성을 저해하였다. CF-30-Ⅳ- 4-ⅱ는 농도의존적으로 fibrine을 생성시키지 않음으로써 thrombin에 직접 작용하지 않는 antithrombin Ⅲ 의존적 항응고 활성 기작을 보였다. 청각의 항응고 활성은 factor assay와 thrombin의 저해 양식을 고려해볼 때 antithrombin Ⅲ의 활성을 증대시켜 혈액응고 인자 중 serine proteinase의 활성을 저해함으로써 항응고 활성을 나타내는 물질로 판명되었다. CF-30-Ⅳ획분의 in vivo 활성을 측정한 결과 꼬리정맥주사에 의해 150 mg/kg의 농도로 마우스에 투여시 thrombin에 대한 100%의 항치사성 효과를 나타내었다. 또한 CF-30-Ⅳ를 마우스의 꼬리정맥에 주입하고 혈액을 채취 ex vivo 상에서 항응고 활성을 측정한 결과, 생체내에서 100 mg/kg의 농도까지도 시료량에 의존하는 항응고 활성을 보였다. Inhibitory mechanism of the anticoagulant polysaccharide purified from Codium fragile was investigated. The anticoagulant compounds (Cf-30-Ⅳ-4-ⅱ, CF-30-Ⅳ) prolonged the clotting time at both activated partial thromboplastin time (aPTT) and thrombin time (TT). The Inhibition factor assay of instrinsic coagulation pathway in the blood showed that the anticoagulant polysaccharide (CF-30-Ⅳ-4-ⅱ) inhibited other factors such as Ⅷ, Ⅸ, ⅩⅠ and ⅩⅢ of the coagulation cascade, which did not affect the lupus anticoagulant AB activity. In the thrombin inhibition pattern, the CF-30-Ⅳ-4-ⅱ did not directly influence the fibrine formation mediated by thrombin but affected the anticoagulant activity through the activation of antithrombin Ⅲ. Base on these result, the anticoagulant polysaccharide (CF-30-Ⅳ-4-ⅱ) was considered to inhibit serine protease involved in the blood coagulation cascade through the enhancing antithrombin Ⅲ activity. The residual effects of anticoagulant activity and antithrombosis were tested with ICR mice. The anticoagulant polysaccharide (CF-30-Ⅳ) kept its anticoagulant activity for 6 hrs with 100% survival at a dose of 150 mg/kg in the antithromboisis test. The anticoagulant effect of CF-30-Ⅳ in ex vivo was proportional to the concentration of intravenously injected dose up to 100 mg/kg.

The purpose of this study was to provide basic data for future research and suggest product development and market segmentation strategies by identifying the perceptions and consumption behaviors of vegetarians in each segment of the vegetarian market. According to food consumption value, a total of three market segments were derived, and the markets were named based on their characteristics, including 'environment and animal protection', 'multiple consideration' and 'low interest'. As a result of analyzing the perception of vegetarian-based food, "environment and animal protection" and "multiple consideration" presented positive perceptions of a vegetarian food product. Conversely, the group stating low interest expressed negative perceptions of the vegetarian food product. An analysis of the requirements for development for vegetarian-based foods products (eg. aquafaba), indicated that the development requirements for all products, except cultured and processed meats, were high.?Considerable demand was observed for vegetarian menus and vegetarian restaurants. As a result of the analysis on the necessity of the elements of the vegetarian restaurant menu, the subjects that stated "multiple consideration" had significantly higher awareness of issues related to vegetarian foods than others.

Mare milk has a unique composition compared to other animal milks. This study was to determine the content of vitamin A in mare milk using HPLC and compared with cow milk. The RT(retention time) of vitamin A by HPLC was about 4.4 min in mare and cow milk. The results showed that vitamin A content of cow milk was higher than that of mare milk in each gram of milk sample. And the vitamin A content of mare cream was lower than that of cow cream in each gram of lipid. Consequently, vitamin A content of cow milk was higher than that of mare milk.
