        The education based on synesthesia has been used to be applied for several years. Especially, We focused on the Coloured-hearing Synesthesia for music education for children who have difficulty in practicing pitch by using the serious game based on Coloured-hearing theory. Also, smart platform is flexible for several sort of video games so we expect good accessibility for children. For proving the effectiveness for education by using this technology and theory, we design the serious game for music called “Bunny’s Cave” based on Coloured-hearing theory and conduct the usability test aimed at 3rd grade student in elementary school.

        본고는 한국어 학습자들에게 문법을 효과적으로 교수할 수 있도록 형태초점 과제를 활용하여 문법을 제시하는 방법에 대해 알아보는 데에 목적 이 있다. 이를 위해 형태초점 과제의 유형에 대해 살펴보고 그 중 문법 제시 방법에서 사용할 수 있는 과제의 유형을 추출한 후 과제를 설계, 실제 예를 보였다. 언어교육에서 문법은 의사소통의 정확성을 위해 꼭 필요한 지식 중 하나이다. 한국어 교육에서 문법 교수의 변화는 문법 연습과 생산 방식의 변화에 초 점이 맞춰져 왔다. 그러나 학습자는 능동적으로 지식을 구성해 나가는 존재이기 때문에 학습자의 발견 학습을 촉진시킬 경우 더 효율적인 문법 교수가 가능하다. 이를 위해 기존의 한국어 문법 교육의 제시 단계에서 형태초점 과제를 제시하여 학습자들의 발견 학습을 촉진시킨 후 문법을 설명, 연습, 생산하는 방식으로 진행할 수 있을 것이다.

        For the purpose of reuse the wasted by-products from the skate process to the health functional food or medicinal material, chondroitin sulfate was extracted from the skate cartilage with the method of hydrolysis with protease enzyme, and the contents of chondroitin sulfate and hydrolyzed protein were measured qualitatively and quantitatively. The effects of chondroitin sulfate on body weight or liver weight changes, hepatotoxicity elimination and anti-inflammatory actions were measured from in vivo test with feed-treated mice. From the hydrolytic extraction of skate cartilage with the mixture of 1% alcalase and 1% protease for 4 hours, the extraction yield of chondroitin sulfate was about 32.55%. The content and molecular weight of chondroitin sulfate was 26.63% and 2.85×105 Da., respectively and the content ratio of chondroitin sulfate to protein was measured to 1 to 2.76 with gel permeation chromatography. For the odor component, trimethylamine decreased about 30% but almost not ammonia from chondroitin sulfate with the treatment of activated carbon. From the feeding chondroitin sulfate to mice, the control effect of body and liver weights decrease was measured, anti-inflammatory action and hepatotoxicity elimination action were also measured. From these results, process operation conditions for manufacturing of chondroitin sulfate were suggested.

        The aim of this study was to investigate and development collagen peptide materials from skate skin. Protein and fat content of collagen peptide showed about 95% and 0.1%, respectively. Average molecular weight of collagen peptide was measured as 1,015. In the analysis of amino acid, glycine and hydroxy proline content in collagen peptide was 19.32% and 16.25%, respectively, showing a typical characteristics of the collagen peptide. In obese db/db mice ingested 500 mg/day of collagen peptide for 18 days, the amounts of food and water intake were decreased considerably, contents of triglyceride, total cholesterol were decreased significantly in white adipose tissue of db/db mice. The final yield of collagen peptide was 17.23% in the optimized process for mass production. These results indicate that collagen peptide from skate skin may serve as candidates of fat reduction in adipose tissue and could be used as functional food and cosmetic ingredients.
