  • The purpose of this study was to investigate the quality of duck ham formulated with duck skin through the pre-emulsification process. The experiments to investigate the quality characteristics of duck ham were carried out to measure proximate composition, cooking loss, emulsion stability, pH, color, texture profile analysis, apparent viscosity, and sensory characteristics. Duck ham was prepared with various ratios of duck skin in pre-emulsion as follows: Control (duct skin 30%), T1 (duck skin 20% + pre-emulsified duck skin 10%), T2 (duck skin 15% + pre-emulsified duck skin 15%), T3 (duck skin 10% + pre-emulsified duck skin 20%), and T4 (pre-emulsified duck skin 30%). As the ratio of duck skin to pre-emulsified skin changed, the quality of duck ham in terms of moisture content, fat content, cooking loss, emulsion stability, lightness, textural analysis, apparent viscosity, and overall acceptability changed. The moisture content of T2 was the highest (p<0.05) and that of the control and T4 was the lowest (p<0.05). The fat content of control was higher than all treatments (p<0.05). T2 had the lowest values in cooking loss, total expressible fluid, fat separation, hardness, springiness, and gumminess (p<0.05). The score of overall acceptability of all treatments with pre-emulsified skin was higher than control (p<0.05). Therefore, the pre-emulsification process can improve the quality characteristics of duck ham and 1:1 ratio of duck skin and pre-emulsified skin was the proper ratio to improve the quality characteristics of duck ham.

  • Purpose: This study analyzed recent trends of instrument usage assessing cognitive function of breast cancer patients undergoing chemotherapy. Methods: The researcher collected 64 studies outside the country that were published between January 1996 and August 2010. Results: There was no study on the instrument assessing all domains of cognitive function in breast cancer patients undergoing chemotherapy. Most instruments assessing cognitive function of breast cancer patients have been used for patients with dementia, depression, and/or organic brain damage. Also the objective neuropsychological tests such as the grooved pegboard for the psychomotor area, RCFT copy in visuospatial skill area and the WAIS-III block design have low sensitivity for measuring cognitive function in breast cancer patients, thus they are not good for applying to breast cancer patients. Conclusion: There is a need to develop an instrument which has good sensitivity and specificity for measuring the cognitive function of the breast cancer patients who experienced cognitive impairment after chemotherapy treatment. In addition, the developed instrument needs to be accessible and feasible in any nursing clinical setting for the purpose of accurate assessment and evaluation of the cognitive function among breast cancer patients.

  • The objectives of this study were to investigate the quality characteristics of restructured pressed smoked duck steak from the breast meat of Cherry Valley ducks. Different levels of isolated soybean protein (ISP) (0, 15 and $30g{\cdot}kg^{-1}$) or carrageenan (5, 10 and $15g{\cdot}kg^{-1}$) were added to manufacture the restructured pressed smoked duck steak. The results were as follows: No significant differences were observed for moisture, crude fat, crude protein, cooking loss and water holding capacity of products from all treatments. The panel test scores showed that color, flavor and binding ability of products were considered acceptable. The drip loss in control sliced-products was significantly higher than products containing ISP or carrageenan (p<0.05) during storage at $-18^{\circ}C$ for 12 weeks. The pH value, volatile basic nitrogen (VBN) value and thiobarbituric acid (TBA) value of vacuum-packaged products did not change significantly during storage at $-18^{\circ}C$ for 6 weeks. However, TBA values increased with storage time. The viable bacterial counts were about $10^{3}-10^{4}CFU/g$ during storage at $-18^{\circ}C$ for 12 weeks. The products remained good quality during the storage period.

  • 함기 포장과 진공 포장이 냉장 저장 중 오리고기의 육색, 지방 산화 및 지방산 조성에 미치는 영향을 조사하였다. pH는 가슴육이 다리육에 비해 낮았으며, 냉장 저장 중 가슴육이 다리육에 비해 육색의 변화가 크게 나타났다. 다리육의 조지방 함량이 가슴육에 비해 약2배 정도 높았으며, 저장 3일 째부터 전단가가 낮아졌다. 함기 포장은 진공 포장에 비해 냉장저장 중 다리육의 지방 산화를 촉진하는 것으로 나타났으며, 지방 산화는 palmitic acid 함량의 감소와 linoleic acid 함량의 증가와 관련이 있는 것으로 나타났다 결과적으로 오리고기의 장기적인 냉장 유통을 위해서는 함기 포장보다 진공 포장을 하는 것이 바람직할 것으로 사료된다.
