The purpose of this study was to understand the interrelationships among customers'perceived values, switching cost, and loyalty to a family restaurant. Based on 328 patrons obtained from empirical research, this study reviewed the reliability and fitness of a research model and verified three hypotheses using the Amos program. The hypothesized relationships were tested in the model simultaneously using a structural equation model (SEM). The proposed model provided an adequate fit to the data, $x^2$=341.01 (df=154), p<0.001, CMIN/df 2.21, GFI 0.91, NFI 0.94, IFI 0.97, TLI 0.96, CFI 0.97, RMSEA 0.06. The results showed that utilitarian values (${\beta}$=0.27) as customers' perceived values elements in a family restaurant, had a positive (+) influence upon switching cost. Switching cost had a significant positive (+) effect on the behavioral loyalty (${\beta}$=0.16) and attitudinal loyalty (${\beta}$=0.16). Hedonic values (${\beta}$= 0.41) and utilitarian values (${\beta}$=0.26) had a positive (+) influence on customer's behavioral loyalty. Additionally, a customers hedonic values (${\beta}$= 0.30) and utilitarian values (${\beta}$=0.32) had a significant positive (+) effect on attitudinal loyalty.

The antimicrobial effect of ${\beta}$-lactam antibiotics, which had ${\beta}$-lactamase inhibitor activity, on Staphylococcus aureus isolated from mastitis was investigated in this study. Out of 166 isolates, 99 isolates (59.6%) produced ${\beta}$-lactamase, and 98 isolates of 99 were ${\beta}$-lactamase positive in above $12.5{\mu}g/m{\ell}$ MIC of penicillin. In the providence distribution, ${\beta}$-lactamase production rate of 4 providence, Gangwon, Gyeonggi, Chungcheong, and Jeolla was 100%, 65.7%, 58.8%, and 50.0%, respectively. Antibiotic activities of ${\beta}$-lactam antibiotics against lactamase positive isolates also were investigated. Antimicrobial effects of ampicillin/sulbactam or amoxicillin/clavulanic acid treated group were better than ampicillin or amoxicillin treated group. In antimicrobial effects on intracellular S aureus, there was no difference 1 hour and 4 hour treatment in control, ampicillin, and amoxicillin group, but in 18 hours treatment, ampicillin/sulbactam or amoxicillin/clavulanic acid had a better effect than ampicillin or amoxicillin (p<0.05).

The fragment in intron I of FSH-${\beta}$ gene was amplified by PCR. According to the polymorphism, we analyzed the distribution of FSH-${\beta}$ retroposon in different pig breeds; its inheritance pattern in Large White${\times}$Meishan reference family; and the association of FSH-${\beta}$ retroposon with litter size, female reproductive organs measurement, ultrasonic backfat and other traits. The results showed that almost each Chinese indigenous pig had the retroposon, while foreign pig breeds rarely had; the frequencies of porcine FSH-${\beta}$ retroposon were strongly associated with breeds (p<0.01); the pattern of inheritance was consistent with Mendelian fashion; total number born (TNB) and number born alive (NBA) were increased per FSH-${\beta}$ retroposon (p<0.01) with additive effects of 1.2-1.8 and 1.4-1.8 pigs/litter, respectively; between the FSH-${\beta}$ retroposon carriers and non-carriers, there was an insignificant difference in the measurement of female reproductive organs, body weight at birth, backfat thickness, loin meat height, lean meat percentage, teat number, days to 100 kg, and average daily gain.

Purpose: The purpose of this study was to compare the antioxidant level, serum cholesterol and skin ${\beta}$-carotene, of female elderly who had been living more then 10 months in institutions which offered either vegetarian or non vegetarian diet. Methods: Total of 110 female elderly, 56 from institution serving vegetarian diet and 54 from nonvegetarian diet, were recruited from institutions located in S and N city in Korea. ${\beta}$-carotene level was measured on their palm using Pharmanex Biophotonic Scanner and annual health evaluation data was utilized for the analysis of serum cholesterol. Results: The subjects on a vegetarian diet had a significantly higher level of phosphorus, carotene, and folic acid. The elderly who were living in an institution offering a vegetarian diet had a lower level of serum cholesterol and higher level of skin ${\beta}$-carotene, compared to those living in an institution offering a non-vegetarian diet. Conclusion: This study reveals that a vegetarian diet is beneficial in increasing skin ${\beta}$-carotene level, decreasing serum total cholesterol level. The skin ${\beta}$-carotene measurement appear valuable as a bio-marker of antioxidant intake. Further study on antioxidant food and effective serving strategy for elderly are recommended.
