Background: A significant number of patients complain of persistent pain or neurologic symptoms after lower back surgery. It is reported that facet joint pain plays a role in failed back surgery syndrome. To the best of our knowledge, there are few studies that have investigated the outcome of radiofrequency neurotomy in the patients with failed back surgery syndrome. Methods: The study group was composed of thirteen patients who were operated on due to their low back pain, and they displayed no postoperative improvement. All the patients underwent double diagnostic block of the lumbar medial branch of the dorsal rami with using 0.5% bupivacaine. The patients who revealed a positive response to the double diagnostic block were then treated with percutaneous radiofrequency neurotomy. The effect on their pain was evaluated with using a 4 point Likert scale. Results: Eleven patients revealed a positive response to the double diagnostic block. Ten patients were given percutaneous radiofrequency neurotomy. Nine patients showed sustained pain relief for 3 months after the percutaneous radiofrequency neurotomy. Conclusions: We found lumbar facet joint syndrome in the patients with failed back surgery syndrome by performing double diagnostic block and achieving pain relief during the short term follow-up after percutaneous radiofrequency neurotomy of the lumbar zygapophysial joints. This suggested that facet joint pain should be included in failed back surgery syndrome.

The quantitative analysis of chitooligosaccharide was compared to using colorimetry and HPLC method. HPLC method required less than 10mins per sample in analytical time of glucosamine and its the recovery rate was 98.4% (10 mg/ml, w/v). Also there was no the effects of interfering substances(false positive response) by HPLC method. The content of chitooligosaccharide in processed chitooligosaccharide products obtained using HPLC showed lower levels compared to colorimetry. Thus, HPLC method was more sensitive, effective and precise than the colorimetry currently used to determine the glucosamine of chitooligosaccharide.

The purpose of this study examined the moderating effect of maternal emotion-related socialization behaviors on the relations between preschooler's effortful control and prosocial behavior. In this study, subjects were 153 preschoolers and their mothers. The major results were as follows; there was a moderating effect of maternal emotion-related socialization behaviors on the relationship between preschooler's effortful control and prosocial behavior. Specifically, maternal negative emotion expression and response to the preschooler's positive emotion moderated the effect preschooler's effortful control on prosocial behavior. In conclusion, the impact of effortful control on preschooler's prosocial behavior were significant. Also, maternal emotion-related socialization behaviors(i.e., negative emotion expression and response to the child's positive emotion) affected on preschooler's prosocial behavior. The findings of the study will contribute to help maternal emotional interaction with their preschool aged children.

In this paper, we have improved a novel (ECB) mode using tilt angle in the unique condition by hot-plate equipment. The new control of tilt angle for nematic liquid crystal (NLC) with negative and positive dielectric anisotropy on the rubbed homeotropic polyimide (PI) using baking method by Hot-plate equipment was investigated. LC tilt angle decreased with increasing baking temperature and time. Especially, the low LC tilt angle of positive type NLC $({\Delta}n>0)$ on the rubbed homeotropic PI surface by increasing temperature and time was measured. The EO characteristics of the novel ECB mode using control of tilt angle on the homeotropic surface than that of conventional OCB cell can be improved. We suggest that the developed the Novel ECB cell using control of tilt angle on the homeotropic surface is a promising technique for the achievement of a fast response time and a high contrast ratio.

To demonstrate their possibilities as an enhanced vaccine delivery system, protein-loaded Poly lactide glycolide copolymer (PLGA) microspheres were prepared with different physical characteristics. Ethyl acetate (EA) solvent extraction process was employed to prepare microspheres and the effects of process parameters on drug release properties were evaluated. The biodeuadability of microspheres was also evaluated by the pH change and GPC (Gel permeation chromatography). Primary IgG antibody responses in BALB/c mice were compared with protein saline solutions as negative controls and adsorbed alum suspensions as positive controls after single subcutaneous injection for in vivo studies. The microspheres showed a erosion with a highly porous structure and did not keep their spherical shape at 45 days and this result could be confirmed by GPC. In vitro release of proteinous drug showed initial burst effect in all batches of microspheres, followed by gradual release over the next 4 weeks. PLGA microspheres were degraded until 45 days and the secondary structure of OVA was not affected by the preparation method. Enzyme-linked immunosorbent assays demonstrated that the single subcutaneous administrations of OVA-loaded PLGA microspheres induced enhanced serum IgG antibody response in comparison to negative and positive controls. These results demonstrated that microspheres providing the controlled release of antigens might be useful in advanced vaccine formulations for the parenteral carrier system.

The purpose of this study was to suggest ways for practical food coordination, by examining restaurant-visitor' expectation factors for food coordination in restaurants. Statistical analyses were carried out based on the statistical data collected via survey from the restaurant. visitors. For the data analysis, factor analysis, reliability analysis, frequency analysis, t-test, and ANOVA were applied, using the SAS 9.1(ver.) program. In the results for the general perception of food coordination, the degree of recognition by restaurant visitors for food coordination is not high. However, necessity for food coordination is highly recognized and a 70% of the respondents were positive in their response about an expropriation price. Fitty percent of the respondents indicated a positive response regarding the relationship between the visual effect of the food and a re-visit to the restaurant. Therefore, most restaurant visitors believe food coordination is necessary in restaurants, and expect to pay for it in price.

Objectives : Though a proportion of Alzheimer's disease(AD) patients treated with donepezil have shown positive response on cognition, but the responders' characteristics are still uncertain. This study attempts to identify whether a single oral dose of donepezil(5mg) can change cognition and the relationship between single dose responder items and long-term responder are examined. Methods : Twenty-three AD patients for single donepezil challenge study group and eleven AD patients for controls were participated in the study. Seven days after baseline study for neuropsychological test and EEG, same studies were rechecked after donepezil medication in study group. In donepezil study groups, 12 weeks after donepezil medication, neuropsychological test and EEG were rechecked. Results : After single donepezil challenge, forward digit span, Rey-Osterrieth Complex Figure Test copy, SVLT delayed recall were significantly improved, and beta spectra power in anterior, theta spectra power in posterior field were significantly decreased. According to linear regression analysis, forward digit span after single donepezil challenge was significantly positive correlated with long-term responders. Conclusions : This study suggests that single donepezil medication can significantly change cognitive functions and EEG in AD patients. Among these responsive items, forward digit span was significantly correlated with long-term responder.

Purpose: The purpose of this study was to investigate the patient safety culture in Korean nursing homes using the Nursing Home Survey Patient Safety Culture (NHS-PC), a valid tool, provided by the Agency for Healthcare Research and Quality (AHRQ) and to compare the results with AHRQ data. Methods: Administrators and staff (N=151) of six nursing homes in Seoul, Busan, Kyeonggi Province and Gyeongsangnam Province completed the survey in July, 2010. The data were analyzed using descriptive statistics, positive response rate, t-test, ANOVA, DUNCAN, Cronbach's ${\alpha}$. Results: The total mean (SD) positive response rate for patient safety culture was not significantly different from the AHRQ data. For composite levels, the results of 'handoffs' were significantly higher, and the results of 'feedback and communication about incidents' and 'nonpunitive responses to mistakes' were significantly lower than the AHRQ data. Conclusion: More effective strategies related to nonpunitive responses to mistakes and management activities for patient safety are needed to improve patient safety culture in nursing homes.

In this study, we tried to verify the effectiveness of 3D scans of clothed participants from 20 to 24 year old men in fit analysis process. Carrying out fit analysis, we used 3D scan data and direct fit evaluation with the basic garments made as semi-fitted bodice pattern for men. The result of fit evaluation through 3D scan data showed the expert rated fitting items more positive than direct fit evaluation. Even though, generally there was a no significant difference in the response between 3D and direct fit analysis. Only there was a significant difference in the response to the specific place such as the center front line, neckline, shoulder seam, and etc. There was a no significant difference between the result of 3D scan and direct fit evaluation in the subjects' group. Also the result of assessment of 3D targeting consumers showed very positive and interested in using 3D scans for fit analysis. The ability to rotate the 3D scans for a variety of views proved to be a very effective process to analyze fit. Moreover, digital data is easily accessed at any locations and any time. Fit analysis using 3D scans could be great tool for not only fit evaluation in research but also better fitting in apparel industry.
