        본 연구는 생분해성 용기 개발의 연구성이 대두됨에 따 라서 동물성 재료로 제조한 생분해성 용기의 개발의 목적에 있다. 연구 결과 돈피, 우피, 닭피에 있어서 돈피가 우수한 수율과 단백질 분자량을 가진 것으로 나타났다. 이에 돈피를 이용하여 생분해 용기를 개발하였으며, 단면적 확인 결과 호두 껍질 분말 10%를 첨가한 처리구에서 적은 공극을 보였으며, 호두 껍질 분말 20%를 첨가한 처리구에서 공극의 크기가 큰 것을 확인할 수 있었다. 물성 연구 결과 호두 껍질 분말 10% 처리구가 더 높은 경도를 나타 내었으며, 호두 껍질 분말 20% 처리구가 더 높은 탄력성을 나타내었다. 압축강도는 호두 껍질 분말 20% 처리구가 더 높은 값을 나타내었다. General bacteria, E. coli 연구 결과 모든 일자에서 불검출되어 미생물로부터의 안정성은 더 장기간으로 실험해볼 필요가 있을 것으로 보인다. 또한 높은 항균 능력과 생분해능의 결과를 보여 저장 기간의 안정성이 높은 용기의 개발과 환경의 영향을 최소화 할 수 있을 것으로 판단된다. 따라서 돈피 젤라틴에 난각과 호두 껍질 분말을 넣어 제조한 생분해성 용기의 개발의 기초 데이터로 이용될 수 있을 것으로 생각된다.

        Lactic acid bacteria (LAB) and probiotics have mostly consumed as dairy products such as city milk, fermented drinking yogurt and stirred yogurt, and LAB and probiotics have become popular to contribute to the flavor, taste, or preservation of food. In this study the effects of various milk products on the physicochemical properties of pork loin were determined. Pork loin samples were marinated in city milk, drinking yogurt and stirred yogurt for 24 hours, and were compared with the raw pork loin (control). Proximate, pH, color, shear force, electronic nose, and sensory evaluation were investigated quality properties of pork loin. The pre- and post- cooking pH was lowest in pork loin marinated in stirred yogurt(p <0.05). The pre-cooking lightness was significantly higher in pork loin marinated in city milk(p<0.05). The redness of pork loin marinated in stirred yogurt and drinking yogurt were significantly higher(p <0.05), but the shear force of pork loin marinated in stirred yogurt was significantly lower(P<0.05). The sensory evaluation of pork loin marinated in stirred yogurt were the highest(p<0.05). These results showed that various milk product marinating could be used to improve the quality characteristics and flavor of pork loin.

        It is difficult to make an accurate estimate of the economic value and effects on societal economy of Nano-technologies. This research measures an economic value of Nano-technologies quantitatively and analyzes its influences on societal economy. This paper chooses some major industries as analysis targets and adapts the DEFRA comparative methodology model which has been developed in the UK and recommended by OECD. For this reason, some industries which are in range of economic value assessment were investigated and related data were collected. Also, the economic value and societal influences of Nano-technologies were calculated, through the procedure of the model. In addition, this study conducts a questionnaire to experts for the validity of measurement results and procedures. This paper suggests a guideline for economic value and effects on societal economy of Nano-technologies assessments through quantitative Defra comparative methodologies.
