This study was performed to evaluate physicochemical properties of model sausages with various levels of pressed cherry fruit extracts alone or in combination with tomato powders as a partial replacement of sodium nitrite. In study 1, physicochemical properties of model sausages were not affected by the addition of pressed cherry fruit extracts(p>0.05), except for Hunter L(lightness) and Hunter a(redness). Model sausages containing pressed cherry fruit extract(T1, 0.5% and T2, 1.0%) decreased lightness, whereas redness of REF(156 ppm sodium nitrite) was not different from T2(p>0.05). However, those with cherry fruit extract at 1% were proper to improve the hunter color values, especially redness values. In study 2, physicochemical properties of model sausages were not affected by the addition of pressed cherry fruit extract and tomato powders in selected nitrite contents, except for color and cooking loss(p>0.05). In color values, REF was the highest level, and T2, T4, and T5 was significantly low level in lightness (Hunter L). T2 was the highest value in cooking loss(%) among other treatments. The redness values(Hunter a) of T5(75ppm, nitrite, 1% pressed cherry fruit extract and 0.5% tomato powder) were not different from REF which had highest redness values(P<0.05). In conclusion, the combination of pressed cherry fruit and tomato powder might be considered as an alternative method to partially replace with sodium nitrite in pork model sausages.

This study was to examine the service and the product evaluation factors of Korean internet fashion shopping malls and to suggest marketing implications for Korean internet fashion shopping malls wanting to expand into the Chinese market. This study conducted a questionnaire survey for college female students in Qingdao, China, who have shopped at Korean internet shopping malls, and 310 surveys were used in the final analysis, frequency analysis, factorial analysis, and regression analysis. The results of the study were as follows. First, Most of the respondents answered that they found the Korean internet fashion shopping malls through the internet, and the most purchased item was outer clothing. Second, the system stability and web site structure excellence factors had a positive influence on the service satisfaction for the shopping mall 'S', while the system satisfaction, service efficiency, interactivity and web site structure excellence factors had positive influences on service satisfaction for the shopping mall 'P', and the system satisfaction, service efficiency, interactivity factors had positive influences on service satisfaction for the shopping mall 'N'. Third, examining the correlation between product satisfaction for the shopping mall 'S', 'P', and 'N' with fashion product evaluation factors showed that, design factors and quality excellence factors of the three shopping malls had positive influences on product satisfaction. The results of this research provide useful information in forming an efficient operating system and improving marketing strategies for internet fashion shopping malls planning to enter or having already entered the Chinese market.

국제전기기술위원회의 문서 IEC 60601-1의 3판 규격과 IEC 60601-2-45의 개별 규격에서는 진단용 X선 장치에서 X선 피폭 선량 정보를 표시하고 그 정확성을 명시할 것을 권고하고 있다. 하지만 임상에서 사용 하는 부착형 공기커마 면적선량계는 교정에 어려움이 있다. 이에 본 연구에서는 임상에 적용 가능한 RQR 표준 선질을 이용하여 공기커마 면적선량계의 에너지 의존성과 정확도를 평가하였고 임상에서 간접 교정을 시행할 수 있도록 방법론을 마련하고자 하였다. RQR5의 표준 선질에서 시행한 시험에서 부착형 공기커마 면적선량계는 –7.5%의 오차를 나타냈고, RQR8의 표준 선질에서는 –10.3%의 오차를 나타냈으며 시험한 모든 RQR 선질에 대해 평균 절대오차는 8.30%±2.85%를 나타내 IEC 60580과 AAPM TG 190의 조건을 만족하였다. 본 연구에서 도출한 공기커마 면적선량계의 교정 방법은 임상에서 사용하는 공기커마 면적 선량계의 간접 교정법으로 사용할 수 있을 것으로 기대한다.
