  • The use of edible insects to replace meat protein is important to ensure future global food security. However, processed foods using edible insects require development to enhance consumer perception. Here, we examined the physicochemical characteristics and rheological properties of emulsions prepared from different edible insect larvae. Three edible insect species (Tenebrio molitor, Allomyrina dichotoma and Protaetia brevitarsis seulensis) were used to prepare larval emulsions that were formulated with 65% of insect larvae, 20% of pork back fat, and 15% ice. The A. dichotoma emulsion had the highest pH and lightness, redness, and yellowness values, while the T. molitor emulsion had the lowest pH and lightness, redness, and yellowness values. The T. molitor emulsion had the highest hardness, gumminess, chewiness, and apparent viscosity values but the lowest springiness and cohesiveness values. According to the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis, T. molitor had the thickest bands, followed by P. brevitarsis seulensis. The differential scanning calorimetry distributions for the T. molitor and A. dichotoma emulsions showed one peak, while that of the P. brevitarsis seulensis emulsion had two peaks. The collective results suggest that T. molitor was the most suitable candidate (of the three tested species) for use as a meat replacement in terms of its physicochemical and rheological properties. It is important that such properties of insect-based emulsions are maintained using various technologies.

  • Purpose: The purpose of present study was to discover the experience of the body of aged women, having had disease. Thus, the researcher tried to explore the perception of the informants and the context in which this perception emerged. Methods: 9 aged women who had disease or trauma were recruited by snow balling and theoretical sampling methods. The iterative data collection and analyzing process proceeded between September, 1999 and January, 2005. Questions posed to the informants included: "What major change in your body comes from the disease?" "How did you feel about yourself after having had disease?". Data from interviews and participant observation was taken as text. The text was analyzed using the ongoing process of qualitative content analysing method and taxonomy of Spradley. Results: Disease gives aged women a chance to reinforce the meaning of their body: the body as the most low valued component of a human, the body as a wholistic field of interacting each component of human and with natural environment and cosmos, and the body as a source of group identity. These meanings were constructed in their life world by the rules of hierarchy, reciprocity, and group cohesiveness. Conclusions: The human body is constructed as a cultural being by a social process. Nursing is concerned with the biological body and the social body. The results of this study can serve to help understand the socialization of the body and to construct a somology of nursing.

  • Subsequent to major changes in workplace such as communication method, uncertain organizational environment, and globalizaiton, several studies in workplace have explored the effects of those changes on work outcomes. Especially, employees need to have the balance in working alone and working with others. The purpose of this study is to examine the effects of control over the physical environment by individuals and the effects of flexibility on individual and group work outcomes in the workplace, to examine the effects of distraction on work outcomes, and to suggest a interrelationships among variables. In this study, four hundred and nine questionnaires were collected from employees of three manufacturing corporations in Michigan, U. S. In order to explore the causal interferences among multiple relationships suggested in this study, path analysis was employed using Lisrel 8.54. The results indicated that control over the physical environmental features of the workplace positively influenced job satisfaction. The findings also supported the hypothesis that flexibility is positively related to task group cohesiveness. It was found that distraction was negatively associated with control and flexibility. However, it was not supported that control was positively associated with perceived performance. This study found control and flexibility in the workplace to be important. Some practical implications were suggested emphasizing that control and flexibility allow limited resources to be used in ways that permit individuals to work effectively within a changing work environment.

  • The purpose of this study was to investigate the effects of the addition of various amounts (0, 1, 3, 5%) of Mokdanpi(P. suffruticosa) powder on the shelf life and the physicochemical, sensory characteristics of rice cakes and noodles to examine the possibility of using Mokdanpi as a natural food preservative for food products. The decrease in the moisture content of rice cake and noodle samples during storage was much less in Mokdanpi-added groups than the control group. The color L value increased and a and b values decreased in the rice cake samples, and color L value, b value decreased and a value increased in the noodle samples during storage. The microbial growth was less in Mokdanpi-added groups than the control group. In sensory evaluation, there were no significant differences among the control and 1, 3%-added groups in terms of color, flavor, taste, moistness, cohesiveness and overall quality; however, 5%-added groups received significantly less score than others (p<0.05). As the storage time increased, the sensory scores decreased significantly in the control and 1 %-added groups of both rice cakes and noodles (p<0.05), but no changes were observed in 3, 5%-added samples. The results suggested that Mokdanpi is effective in increasing the shelf life and inhibiting the staling of rice cakes and noodles.

  • In this study, Sulgidduk samples were prepared with substitutions of 1, 2, 3, and 4% tomato powder, along with a control, and were then analyzed for quality characteristics such as moisture content, water activity, color, textural characteristics, and sensory qualities, in order to determine the optimal ratio of tomato powder in the formulation. According to the results, moisture content and water activity were not significantly different among the Sulgidduk samples. In terms of color, as the level of tomato powder content increased, lightness decreased, while the a-value (+redness/-greenness), and yellowness increased. For the textural characteristics, the samples showed significant differences for hardness, adhesiveness, and gumminess, while fracturability was not significantly different. In addition, the samples containing tomato powder presented significantly higher springiness, cohesiveness(except the 1% substitution level), chewiness, and resilience than the control group. In the sensory evaluation, the control group had significantly higher scores for color and flavor as compared to the tomato powder samples. Furthermore, flavor and overall acceptability decreased, while tomato flavor, sourness, and off-flavor increased with increasing tomato powder content. Sweetness and after-taste were not significantly different among the samples. In conclusion, the results indicate that substituting 2${\sim}$3% tomato powder in Sulgidduk is optimal for quality, and provides a product with reasonably high overall acceptability.

  • The purpose of this study was to investigate the quality characteristics of bread made with 1%, 3%, 5%, and 7% of Bigeumdo Seomcho powder (Spinacia oleracea L.). The pH of dough and bread decreased as the amount of addition increased; 7% indicated the lowest. The moisture level correlated negatively with the powder addition, but the difference was not statistically meaningful (p<0.05). As the amount of addition was increased, the intensity of color increased but the volume decreased. The brightness and redness of the bread decreased as the amount of addition increased. The volume, specific volume, and baking loss rate correlated negatively with the powder addition. Regarding springiness, cohesiveness, and gumminess, the experiment group was higher than the control group and they lowered as the addition amount increased. The brittleness showed positive correlation with the addition amount. Out of the amino acids of bread, glutamic acid showed the highest value as the amount of addition was increased. Overall, it is possible to produce bakery bread using functional ingredients.
