The effect of Pleurotus eryngii and meat particle size on properties of sausage quality was investigated. Pleurotus eryngii and meat were processed and combined in the following three ways: T1 (minced Pleurotus eryngii+emulsified meat), T2 (chopped Pleurotus eryngii+emulsified meat) and T3 (chopped Pleurotus eryngii+chopped meat). The pH values of sausages showed T1 to be significantly higher (p<0.05) than T2 and T3. The shear force values showed no significant difference between treatments. T2 and T3 had significantly higher hardness values (p<0.05) than T1. With regard to color, the lightness and whiteness of sausage were significantly higher (p<0.05) for T1 and T2 than for T3. No significant differences between treatments were found regarding redness and yellowness. Panels rated T2 and T3 significantly higher (p<0.05) for aroma and flavor than T1. T2 was rated significantly juicier (p<0.05) than T1, T2 and T3 were rated significantly higher (p<0.05) for overall acceptability than T1.

The purpose of this study was to examine the level of stress, healthcare accreditation related job stress, adaptation, and turnover intentions, as well as to identify influencing factors of turnover intentions for operating room nurses. This study employed a descriptive correlational design. The data were collected from 163 operating room nurses using a structural questionnaire. Stress was different by age (F=5.629, p=.004), marital status (t=-2.907, p=.004), and children (t=-2.623, p=.010). Healthcare accreditation related job stress was different by age (F=11.924, p<.001), marital status (t=-4.747, p<.001), children (t=-4.434, p<.001), work experience in the OR (F=6.000, p=.003), and work reasons in the OR (t=-2.543, p=.012). Turnover intention was different by age (F=21.472, p<.001), education level (F=4.997, p<.008), religion (t=3.235, p=.001), work experience in the OR (F=13.599, p<.001), position (t=3.222, p=.002), work reasons in the OR (t=-3.001, p=.003), and a shift pattern of duties (t=-2.797, p=.006). Turnover intention was significantly correlated with stress, healthcare accreditation related job stress, and adaptation. Factors affecting turnover intention were healthcare accreditation related job stress, adaptation, and age. These factors accounted for 36.2% of turnover intention. These results suggest that relief of stress and healthcare accreditation related job stress and interventions for improving stress management.

The purpose of this research was to study the characteristics of Hanwoo (Korean native cattle) beef fed without mugwort (T0) and Hanwoo beef fed with mugwort (T1) during storage at$3{\pm}1^{\circ}C$ for 50 days. During cold storage, $a^*$ and $b^*$ value of meat color for T1 decreased slowly compared to those of T0, there was significant difference between T0 and T1 after 40 days (p<0.01). The shear force value of T0 and T1 decreased (p<0.001), and the drip loss and cooking loss of T0 and T1 increased (p<0.05). However, there was no significant difference between T0 and T1. During refrigeration period, the volatile basic nitrogen contents of T1 slowly increased compared to T0, there was significant difference between T0 and T1 after 50 days (p<0.01). The total plat count and thiobarbituric acid value of T1 slowly increased compared to T0, and there was significant difference between T0 and T1 after 30 days (p<0.01). Further, the decrease of the antioxidant activity of T1 was delayed, there was significant difference between T0 and T1 after 40 days (p<0.05). There was no significant difference of taste, juiciness, or tenderness of cooked meat between T0 and T1. The aroma and palatability of cooked meat for T1 fed with mugwort were significantly superior than those of T0 at day 30 after storage (p<0.05).

This study was conducted to evaluate the efficacy of wheat and wheat bran  as the source of phytase in a 5 week broiler feeding trial. One thousand day-old broiler chickens(Ross$^{(R)}$) were divided into 20 pens of 50 broilers(25 male and 25 female) each. Four pens were randomly arranged to one of the five dietary treatments: T1, control diet containing normal nonphytate P(NPP) ;  T2, T1 － 0.1% NPP; T3, T2 ＋ 600IU microbial phytase(NOVO$^{(R)}$) per kg diet; T4, T2 ＋ 600IU plant phytase from wheat and wheat bran; T5, T2 ＋ 600IU plant phytase from wheat and hydrothermally treated wheat bran. Reduction of NPP level by 0.1%(T2) reduced weight gain and feed intake but plant phytase treatments(T4 and T5) recovered the lost performance. Plant phytase treatments showed better (p<0.05) weight gain and intake than the microbial phytase treatment(T3). There was no difference between regular wheat bran treatment(T4) and hydrothermally treated wheat bran treatment(T5). Mortality was the highest by low NPP diet(T2). Availability of ether extract and crude ash of grower diet was the highest(p<0.05) in normal wheat bran diet(T4). Availability of Ca and P of grower diet was the highest(p<0.05) in T4 followed by T3 and T5. Availability of Mg, Fe and Zn was drastically improved by phytase treatments(T3, T4 and T5). Excretion of Ca, P, Mg, Fe and Zn was the lowest(p<0.05) with microbial phytase treatment(T3). Serum level of Ca and Mg was the highest(p<0.05) with the low NPP treatment(T2). Tibial ash content of T2 and T3 was lower(p<0.05) than that of T1, T4 and T5. However, tibial Ca content was higher(p<0.05) in T1 and T2 than other treatments. Tibial P and Mg contents were the highest(p<0.05) in T1. It was concluded that plant phytase from wheat bran can be effectively used to improve P utilization. Hydrothermal treatment of wheat bran prior to inclusion in the diet had no beneficial effects.

High content of polyunsaturated fatty acid in fish oil makes it very susceptible to oxidation, which prevent fish oil from successful application to food processing or functional foods. To resolve this problem, oxidation stability model of fish oil was developed using the following differential equation : $dp/dt=k{\cdot}p(t){\cdot}[P_{max}\;-\;p(t)]$. This differential equation can be intergrated using analytical techniques to give : $p(t)=P_{max}/[1\;+\;[(P_{max}/P_{(0)})\;-\;-1]{\cdot}EXP(-K_p{\cdot}t)]$. At 50, 60, 70 and $80^{\circ}C,\;K_p$ were 0.00535, 0.01345, 0.02516 and 0.04675, respectively. The proposed model was well agreed with the measured data except for some minor deviations. In addition, $K_p$ was expressed as a function of temperature : $K_p=(1/P_{max})EXP\;[1\;-\;(8148/T)+20.1]$. Where T is absolute temperature($^{o}K$).
