PURPOSE: The aim of this study was to compare the color stability, water sorption and cytotoxicity of thermoplastic acrylic resin for the non-metal clasp dentures to those of thermoplastic polyamide and conventional heat-polymerized denture base resins. MATERIALS AND METHODS: Three types of denture base resin, which are conventional heat-polymerized acrylic resin (Paladent 20), thermoplastic polyamide resin (Bio Tone), thermoplastic acrylic resin (Acrytone) were used as materials for this study. One hundred five specimens were fabricated. For the color stability test, specimens were immersed in the coffee and green tee for 1 and 8 weeks. Color change was measured by spectrometer. Water sorption was tested after 1 and 8 weeks immersion in the water. For the test of cytotoxicity, cell viability assay was measured and cell attachment was analyzed by FE-SEM. RESULTS: All types of denture base resin showed color changes after 1 and 8 weeks immersion. However, there was no significant difference between denture base resins. All specimens showed significant color changes in the coffee than green tee. In water sorption test, thermoplastic acrylic resin showed lower values than conventional heat-polymerized acrylic resin and thermoplastic polyamide resin. Three types of denture base showed low cytotoxicity in cell viability assay. Thermoplastic acrylic resin showed the similar cell attachment but more stable attachment than conventional heat-polymerized acrylic resin. CONCLUSION: Thermoplastic acrylic resin for the non-metal clasp denture showed acceptable color stability, water sorption and cytotoxicity. To verify the long stability in the mouth, additional in vitro studies are needed.

OBJECTIVES: Utilizing social network analysis, this study aimed to analyze the main keywords in the literature regarding the health literacy of and the use of online health information by aged persons over 65. METHODS: Medical Subject Heading keywords were extracted from articles on the PubMed database of the National Library of Medicine. For health literacy, 110 articles out of 361 were initially extracted. Seventy-one keywords out of 1,021 were finally selected after removing repeated keywords and applying pruning. Regarding the use of online health information, 19 articles out of 26 were selected. One hundred forty-four keywords were initially extracted. After removing the repeated keywords, 74 keywords were finally selected. RESULTS: Health literacy was found to be strongly connected with 'Health knowledge, attitudes, practices' and 'Patient education as topic.' 'Computer literacy' had strong connections with 'Internet' and 'Attitude towards computers.' 'Computer literacy' was connected to 'Health literacy,' and was studied according to the parameters 'Attitude towards health' and 'Patient education as topic.' The use of online health information was strongly connected with 'Health knowledge, attitudes, practices,' 'Consumer health information,' 'Patient education as topic,' etc. In the network, 'Computer literacy' was connected with 'Health education,' 'Patient satisfaction,' 'Self-efficacy,' 'Attitude to computer,' etc. CONCLUSIONS: Research on older citizens' health literacy and their use of online health information was conducted together with study of computer literacy, patient education, attitude towards health, health education, patient satisfaction, etc. In particular, self-efficacy was noted as an important keyword. Further research should be conducted to identify the effective outcomes of self-efficacy in the area of interest.

We assessed about growth hormone binding proteins (GHBP) activity which was measured eluted biotin GH fraction with alkaline phosphatase-streptavidine in children with insulin dependent diabetes mellitus (IDDM), short stature due to growth hormone deficiency (GHD), chronic renal failure, short stature due to nutritional deficiency. hypothyroidism and normal control groups using high pressure liquid chromatography protein pak 300 sw column. The following results are observed: 1) There were 3 types of growth hormone (GH) in serum: first GH binded with type I (minor) GHBP suggesting 200K dalton of molecular weight, second GH binded with type II (major) GHBP suggesting 60~70K dalton of molecular weight, and third GH were free form GH suggesting 20~25K dalton of molecular weight. 2) Type II (major) GHBP showed considerable individual variation in all ages. Neonates had the lowest levels of GHBP activity, but by the puberty the levels had increased & remained stable from adolescent to adult periods. 3) GHBP activity of children with IDDM at diagnosis was low value as compared to the same agenormal control group (p<0.05), and difference of GHBP activity among children with IDDM was related with height velocity (r=+0.92). Follow up GHBP activity during insulin therapy was reverse correlation with HbAlc. 4) GHBP activity of children with GHD at diagnosis was a slightly low compared to aged matched control and follow-up GHBP activity after 1 dose GH therapy showed increasing tendency (r=-0.68). 5) Otherwise, children with chronic renal failure, short stature due to nutritional deficiency, and hypothyroidism were assessed lower value than normal control group. Above results, GHBP activity had the lowest levels at neonatal period and then increasing tendency until puberty period and remained steady level until adult period. Regulation of GHBP may be closely related with metabolic control state by insulin, GH, nutritional status, and thyroid hormone..

Serum is free of cellular components. Because DNA is located in the nuclei or mitochondria of cells, serum could be assumed DNA free. Few previously published case reports to date have used serum for DNA typing. Here, we report on human genotyping via short tandem repeat (STR) analysis using serum as a sample, and discuss problems involved in the process.

PURPOSE: The purpose of this study was to investigate the moderating effects of social support between emotional labor and job satisfaction in clinical nurses. METHODS: Participants were 311 clinical nurses and data were collected from July 11th to 18th, 2014. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and hierarchical multiple regression with SPSS 21.0. RESULTS: The job satisfaction indicated a significant relationship to surface-acting (r=-.191, p=.001), deep-acting (r=.179, p=.002) and social support (r=.342, p<.001) respectively. Emotional labor significantly affected job satisfaction (F=11.592, p<.001), and explained 5.4% of the variance in job satisfaction. The social support acted as a moderator on the relationship between emotional labor and job satisfaction at significant level (F=11.416, p<.001). CONCLUSION: The results of this study suggest that it is important to develop social support promoting and stress relief program for clinical nurses to improve job satisfaction.

Based on the limitation of biomedical model of tinnitus, more attention has been paid to personalities or psychological aspects. Depressive disorder, anxiety disorder, and sleep disturbance were comorbid illnesses of tinnitus and research showed that neurobiological mechanisms such as dysfunction of limbic system or HPA axis were common in tinnitus and affective disorders and that comorbid psychiatric disorders enhanced the negative outcome of tinnitus. Recently, more attention is being paid to the relation of tinnitus with personality and the role of stress. Although the causal relation of personality and tinnitus is unclear, stress in itself showed that it can be a trigger in the development of tinnitus, and stress of tinnitus can cause adverse effects. Since the effect of fear-related cognition such as catastrophic thought about tinnitus was revealed more recently, its therapeutic implication should be explored. This review will describe the product of previous research and discuss future direction about psychological factors related to tinnitus.

The incidence of severe hepatitis A virus (HAV) infection has been increasing. However, clinicopathologic features of severe HAV infection that lead to liver transplantation (LT) have not been reported in Korea. We retrieved 16 LT cases with HAV infection during the last 3 years at Asan Medical Center, Seoul, Korea. Fifteen cases progressed to hepatic encephalopathy. Thirteen cases survived with or without complications, and three patients died of sepsis. The explanted liver showed massive or zonal necrosis with moderate to severe cholestasis. The zonal distribution of necrosis was frequently associated with endothelialitis of portal and/or central veins. Degenerative changes of hepatocytes were various in degree and distribution. Viral inclusions were suspected in two cases. Although HAV infection is usually confirmed by serological tests, significant venulitis of central and/or portal veins and viral inclusions, which are rarely observed, can suggest an HAV infection as a cause of massive hepatic necrosis of unknown mechanism.
