This article complies a survey on the replacement of the posterior restorations and accesses possible factors that influence the replacement of posterior restorations. The data was collected from patients that visited department of conservative dentistry from Dec 1st 2003, to Sep 3rd 2004. Teeth was restricted to posterior permanent teeth. 9 dentists recorded age, gender of patients, tooth location, cavity farm and restorative material. They rated marginal adaptation, anatomic form, secondary caries of old restoration by modified Ryge criteria system. The statistical analysis was performed with Chi square test (p < 0.05) for replacement ratio according to patients, tooth factor and One way ANOVA was performed for comparison of old restoration according to restorative material. The results were as follows; 1. The female (62%) was statistically higher ratio than the male (38%). 2. The distribution of replacement case according to age, the rate of replacement was in descending order, 20's (38.3%), 40's (16.8%), 30's (15.9%), 10's (11.1%), 50's (9.2%), 60's (8.7%). 3. The rate of replacement was 88% for molar and 12% for premolar (p $gt; 0.05). 4. The rate of replacement was 39% for maxillar and 61% for mandible (p $gt; 0.05). 5. The material of restorations was amalgam (69%), gold inlay (17%), composite resin (13%). 6. In rating system by modified Ryge criteria system on margin adaptation, there was statistically significant difference between amalgam and gold inlay. But on anatomic form and caries, there was no statistically significant difference among the material of restorations.

The purpose of this study was to analyze fabrics suitable for use as examination gowns to determine whether examination gowns affect imaging during anterior to posterior chest examinations(Chest AP) on a digital X-ray system. Examination gowns in use at five medical centers in Seoul were collected and included modal, tencel, cotton, and rayon fabrics. The selection of fabrics was based on studies that reported fabrics with good tactile, absorbent, stretchable, and wrinkle resistance. Phantoms of five hospital gowns and four fabrics, arranged in overlapping layers from one to eight, were created and examined on a digital X-ray system in both Chest AP examination. The images examined were subjected to a first-step profile analysis, a second-step signal intensity averaging analysis, and a third-step microscopic analysis. The results showed that all nine materials had an increasing impact on the image as the number of layers of fabric increased, with the modal fabric having the least impact on the image in the first, second, and third analyses. In conclusion, as the resolution of digital x-ray systems increases, the impact of examination clothing on the image will increase, and research to find suitable materials for examination clothing will continue to be necessary.

This study identifies consumer satisfaction with medical services and the patient gowns of hospitals. Also analyzed are the elements that influence hospital satisfaction and the general satisfaction with patient gowns. A survey was conducted among Korean male and female ex-patients regardless of their age. A total of 513 responses were analyzed using descriptive statistics, paired t-test, correlations, regression, and factor analysis derived from data collected in April and May, 2009. The results are as follows. The general satisfaction with the hospital recently visited was higher than the general satisfaction with all of the hospitals visited. The satisfaction with medical services were high in good services, trustful medical examinations, easy access to utilities, and clean utilities. Hospital satisfaction was determined by good services, trustful medical examinations, easy access to utilities, patient gowns, and fresh indoor air. The satisfaction factors of general patient gowns were determined as functionality, fabric/design, sewing, and the management system factors. The most important factor explaining patient gown satisfaction was fabric/design, and this was the most unsatisfied factor at the same time.

This study analyzes the effect of patient clothes on hospital satisfaction. We conducted a survey on 272 patients from June 12 to August 14 in 2009. For the statistical analysis of data, t-test, ANOVA, and hierarchical regression analysis were used. The results of the study were as follows. First, the clothing satisfaction of patients depended on age and gender. Elderly patients were more satisfied with patient clothes compared to younger patients and patients with low educational backgrounds were more satisfied with patient clothes. Second, the effect of patient clothes on hospital satisfaction was statistically significant even after controlling for other factors. Third, the effect of patient clothes on hospital satisfaction depended on the age of the patient. In the case of young patients, the hospital satisfaction level increased sharply when they were satisfied with patient clothes.
