Using a nickel-chrome casting alloy called 'Rexillium V' which is also available as base metal alloy for dental ceramic crown, 4 types of mixtures(A, B, C, D) with old and new metal were prepared for cyclic casting. The results of cyclic casting can be outlined as follows: 1. For Vickers hardness after casting, specimen A and D tended to have lower hardness in the course of cyclic casting, while specimen B and C tended to higher hardness. 2. The results of X-ray diffraction analysis showed that major crystal phase contained nickelchrome compounds and carbide. 3. The observation results of SEM photographs after cyclic casting show that there was a significant tendency to have similar structures among experimental groups. 4. The results of EDX analysis after cyclic casting showed that there were little differences in chemical composition between parent metal and base metal alloy. Although industrial nickel-chrome cast alloy did not show any significant change in material properties even through cyclic casting over several times, it is recommended that more there be more in-depth studies on how to detect any potential corrosion, discoloration and toxication of dental ceramic crown implanted in patient's oral cavity.

Candida albicans is now well recognized among the denture stomatitis patients. The broth macrodilution test is the most widely used technique for antifungal susceptibility testing. The purpose of this study was to determine the C. albicans carrier rate of the denture patients in Iksan, chonbuk. To determine the C. albicans carrier rate of denture patients, culture were made from 227 sample taken in Iksan, Chonbuk during July 1997 to August 1997. Also activities of amphotericin B and miconzole against isolates of denture patients of C. albicans were tested by broth macrodilution test using RPMI medium 1640. The results were as follows : First C. ablicans was isolated from 6.6% of denture patients samples and the frequency of isolation fo C. albicans was highest(50%) in the age group of 71-year-old to 80-year-old denture patients. Second, against C. albicans, the MIC range of amphotericn B was $0.06{\sim}0.25{\mu}g/ml$. MIC50 and MIC90 were $0.13{\mu}g/ml$ and $0.25{\mu}g/ml$, respectively. Third, the MIC range of miconazole was $10-{\ge}20{\mu}g/ml$ and MIC50 and MIC90 were $20{\mu}g/ml$ and ${\ge}20{\mu}g/ml$, respectively. It was concluded from this study that C. albicans acrriages from healthy denture individuals only over 60-year-old ages were isolated, they remain susceptible to amphotericin B and not rarely resistant to miconzole.

The purpose of this study was to identify the influence of depression, social isolation, and meaning in life on the swallowing related quality of life in patients with dysphagia. In this study, 87 the dysphagia patients diagnosed with stroke, degenerative disease, and neurological disorder in a general or rehabilitation hospital in Seoul, Gyeonggi, and Incheon were assessed. The data were collected between February and April, 2015 using CES-D, RULS, PIL, SWAL-QOL. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation, and stepwise multiple regression with SPSS 22.0. Of the participants, 20.7% reported having had depression, 92.0% middle-high social isolation and 64.4% existential vacuum. The mean scores were SWAL- QOL 158.89(35.97). Stepwise multiple regression revealed that tube feeding to have the greatest effect on SWAL-QOL(${\beta}=-0.57$, p<.001), followed in order by age (${\beta}=0.26$, p=.001), lower MIL (${\beta}=0.19$ p=.014), and education (${\beta}=0.17$, p=.032). The most influential factor to SWAL-QOL was tube feeding. These variables accounted for 50.7% of SWAL-QOL in dysphagia patients (F=28.84 p=.031). Therefore, it is essential to develop the intervention that can improve the meaning in life in patients with dysphagia. In addition there is a need to study the psychological factors and quality of life of tube feeding.
