본 연구는 푸드카빙 교육을 받은 수강생들이 지각하는 푸드카빙 효용성은 어떠한지 살펴보고, 어떠한 효용성들이 있고, 효용성의 품질 속성은 어떠한지 살펴보고자 하였다. 이러한 연구목적을 규명하기 위하여 푸드카빙 교육을 받은 경험이 있는 수강생을 모집단으로 설정하였고, 설문조사는 2020년 7월 20일부터 8월 20일까지 한 달간 진행되었다. 설문지는 총 500부를 배부하였고, 435부가 회수되었고, 불성실한 설문지 38부를 제외하고 397부가 최종 분석에 사용되었다. 분석결과, 중요 실행 요소로는 푸드카빙 교육은 지루하지 않고, 남녀노소 할 수 있고, 잡생각이 사라지고, 자존감이 높아지고, 자신의 가치가 높아지고, 마음이 편해지고, 우울함이 사라지는 등의 수업 자체에서 오는 만족감의 속성들이 포함되었다. 매력적 요소에는 푸드카빙 기술이 수익으로 연결되고, 강좌를 개설하고, 적은 금액으로 공방을 오픈하는 등의 수익 측면과 관련된 항목들이 포함되었다. 아울러, 기본적 요소에는 집중할 수 있고, 기분이 좋아지고, 자격증을 취득하고, 전문가가 될 수 있다는 측면의 항목들이 포함되었다. 이는 대체로 푸드카빙을 처음 배우는 수강생들이 기본적으로 가지는 목적들이 포함되었다. This study aims to examine the food carving utility perceived by students who received food carving education, the types of the utility, and its quality attributes. To investigate this research purpose, students who had received food carving education were set as a population, and the survey was conducted for one month from July 20 through August 20, 2020. 500 copies of the questionnaire were distributed in total, and 435 copies were collected. 397 copies were used in the final analysis, excluding 38 unreliable copies. As a result of the analysis, important execution factors included the attributes of satisfaction with the class itself, e.g., Food carving education was not boring; it could be done by men and women of all ages; it made cockeyed ideas disappear; it promoted their self-esteem; it enhanced their value; it comforted their hearts; and it made their depression disappear. Attractive elements included revenue-related items, such as food carving skills connected to profits; they could open lectures; and they could open a workshop with little money. Along with this, the basic elements included the following: They could concentrate; they could feel better; they could get a certificate; and they could become an expert. They usually included the purposes the students who would learn food carving for the first time had basically.

Purpose: This study examined the antioxidant activities and meat-tenderizing effects of hardy kiwi (Actinidia arguta) cultivated in Gangwon for the development of a value-added natural tenderizer. Methods: Hardy kiwi was analyzed for its physicochemical properties and antioxidant activities with kiwifruit as a control. Its freeze-dried powder was applied to marinate meat. The cooked meat was then examined for its texture properties. For comparison, meats treated with kiwifruit flesh or skin were tested separately along with a non-treated control. Results: The total reducing capacity and DPPH radical scavenging activity of hardy kiwi were significantly higher than those of kiwifruit flesh and comparable to those of kiwifruit skin. In addition, hardy kiwi showed characteristic patterns of both rapid kinetic behavior and slow kinetic behavior when scavenging DPPH radicals, presumably due to the use of the flesh and skin of hardy kiwi. The compression strain vs. stress curve obtained from texture profile analysis showed that hardy kiwi tenderized the meat effectively, which was comparable to the effects of kiwifruit flesh. On the other hand, meat treated with kiwifruit skin became stiff, which could be attributed to the abundance of dietary fiber in the kiwifruit skin. Conclusion: This study showed that hardy kiwi has potential use as a natural meat-tenderizer that is as effective as kiwifruit, with significantly higher antioxidant activities than the edible portion of kiwifruit.

Electrowetting-on-dielectric(EWOD) of microfluidics is a useful technique to manufacture micro-nano core components. Important factors for droplet drive of EWOD are voltage magnitude, size of electrode, gap between the electrodes, hydrophobic surface, spacer and quantity of droplet. In this study, factors for actual EWOD drive were considered partially in drawing of multiphysics tool. Two fluids as air and water were calculated using the Level set Two-Phase Flow Laminar method in multiphysics tool. At the same time, voltage about each step time is applied using the Conductive Media DC method. We obtained the droplet moving from electrode It to electrode3 and discussed the dynamic changes of droplet by applied voltage in EWOD device and optimal gap between top device and bottom device in fixed factor as electrode size and gap of electrodes.
