Objective : The purpose of this study is to compare the outcomes of two methods for stabilization and fusion : Postero-Lateral Fusion [PLF, pedicle screw fixation with bone graft] and Posterior Lumbar Interbody Fusion [PLIF, cage insertion] for spinal stenosis and recurred disc herniation except degenerative spondylolisthesis. Methods : Seventy one patients who underwent PLF [n=36] or PLIF [n=35] between 1997 and 2001 were evaluated prospectively. These two groups were compared for the change of interbody space, the range of segmental angle, the angle of lumbar motion, and clinical outcomes by Prolo scale. Results : The mean follow-up period was 32.6 months. The PLIF group showed statistically significant increase of the interbody space after surgery. However, the difference in the change of interbody space between two groups was insignificant [P value=0.05]. The range of segmental angle was better in the PLIF group, but the difference in the change of segmental angle was not statistically significant [P value=0.0l7]. Angle of lumbar motion was similar in the two groups. Changes of Prolo economic scale were not statistically significant [P value=0.193]. The PLIF group showed statistically significant improvement in Prolo functional scale [P value=0.003]. In Prolo economic and functional scale, there were statistically significant relationships between follow-up duration [P value<0.001]. change of interbody space [P value<0.001], and range of segmental angle [P value<0.001]. Conclusion : Results of this study indicate that PLIF is superior to PLF in interbody space augmentation and clinical outcomes by Prolo functional scale. Analysis of clinical outcomes showed significant relationships among various factors [fusion type, follow-up duration, change of interbody space, and range of segmental angle]. Therefore, the authors recommend instrumented PLIF to offer better clinical outcomes in patients who needed instrumented lumbar fusion for spinal stenosis and recurred disc herniation.

This study examined the physiochemical and organoleptic properties of the yanggaeng fabricated with different contents of ginger powder. The moisture contents ranged between 39.85% and 47.92%. The yanggaeng made with 0.5 g of ginger powder showed the lowest moisture content of 37.04%, whereas the yanggaeng made with 1.5 g of ginger powder showed the highest moisture content of 47.92%. As for the L value, which indicates lightuess, the yanggaeng made with 1.5 g of ginger powder showed a L value of 13.92, whereas the yanggaeng made with 0.5 g showed the lowest L value of 12.35, (p<0.05). The values for redness (a value) ranged between 4.69 and 5.58, and there was no significant difference as the content of ginger powder increased. The value for yellowness, (b value) ranged between 3.19 and 2.33, and showed a significant decreasing trend as the ginger powder content increased (p<0.05). The sugar concentrations were 53.82~46.56, and decreased as the ginger content increased. The pH ranged between 6.42~6.52, and showed significant differences. As the ginger content increased, changes in hardness, adhesiveness, gumminess, and chewiness, were all significant (p<0.05). Characteristics of cohesiveness and springiness, showed no significant differences. Although there were no significant differences in color, flavor, chewiness, and hardness, there was a decreasing flavor preference as the content of ginger powder increased. There were significant differences in sweetness, moistness, and overall-preference (p<0.05). For overall-preference, the yanggaeng with 1.0 g of added ginger powder showed a high preference level. The study results implied that ginger powder may be used in fabricating yanggaeng. and a 0.5% content of added ginger powder will improve the preference level.

In this study, we investigated the impact of the information richness and reachness on the mobile purchasing and the moderating effect of individual characteristics. We examined the information richness and reachness through SNS information and Push notification of smartphone, respectively. As the moderating variables, we adopted customer's value orientation and innovativeness. In the main-effect model with no moderating variable, both of information richness and reachness showed significant effects on the perceived value of products and purchasing channel. Especially, the impact of information richness was more significant on product awareness, while the impact of information reachness was more significant on channel awareness. In the interaction-effect model with moderating variables, customer's value orientation showed significant moderating effect on the impact of perceived product value. However, customer's innovativeness did not show the significant moderating effect on the impact of perceived channel value. It implies that the impact of information reachness applies to the majority of customers, regardless of her [his] innovativeness. Therefore the organizations might be able to use Push notification to activate the customer's mobile purchasing.

Objectives : To determine the relationships among quality, satisfaction, value and purchase intention in health care service. Methods : The data were gathered from out-patients who had used hospital services. They were asked to assess service quality, satisfaction, service value, and purchase intention. A total of 557 usable questionnaires were gathered. The data were analyzed using SAS version 6.12. The analysis methods employed in the study were confirmatory analysis and covariance structural analysis. Results : Service quality exhibited a significant and positive relationship with satisfaction, service value, and purchase intention. Furthermore, satisfaction had a significant and positive relationship with purchase intention. And finally, service value had a significant and positive relationship with both satisfaction and purchase intention. Based on these findings, it is evident that satisfaction was a mediator between service quality and purchase intention. Also service value played a mediating role between service quality and satisfaction. Conclusions : These results suggest that service quality is an antecedent of satisfaction and sonics value, and exerts a stronger influence on purchase intentions than satisfaction and service value do. Thus, managers may need to emphasize service quality in health care.

This research aims to examine and analyze the impact of customer shifting behavior on the shopping emotion. Based on impulse buying, customers tend to behave recently based on the constructed variables of impulse buying, outlet ambience, hedonic shopping value utilitarian shopping value, and shopping emotion. This study employs samples/survey data of the population consisted of Asian women parents in Indonesia. The survey data of this research is based on observations using time series with cross-section/one-shot, which was done in 2019. The results indicate that variable outlet ambience, hedonic shopping value, and shopping emotion have a positive and significant impact on impulse buying. Whereas the utilitarian shopping value variable has a positive but not significant relationship against impulse buying. There is a positive influence between ambience outlets and utilitarian shopping value on shopping emotion. The variable hedonic shopping value has a negative and not significant relationship towards shopping emotion. The finding of this study suggests that both the retail stores and even the superstores must pay more attention to the design of outlet ambience to create the hedonic shopping value and eventually may attempt the attention of the impulse buying customers.

The purpose of this study was to measure the effects of restaurant service quality dimensions on service value, satisfaction, and behavior intention. A total of 273 questionnaires were completed. A structural equation model was used to measure the causal effects. The results of the study show that the confirmatory factor analysis model presented an excellent model fit. The unrestricted model yielded a significantly better fit to the data than the two restricted models. In the unrestricted model, the effect of reliability on service value was statistically significant. The effects of tangibles and empathy on satisfaction were also statistically significant. As expected, empathy had a significant effect on behavior intention. Moreover, empathy had a significant indirect effect on behavior intention through service value and satisfaction. Restaurants should devote themselves to factors such as reliability in order to improve service value. Also, attention must be given to another important factor, empathy, since this influenced not only satisfaction, but also behavior intention.
