  • Various studies examining the relationship between Ezrin overexpression and response to chemotherapy and clinical outcome in patients with osteosarcoma have yielded inconclusive results. We accordingly conducted a meta-analysis of 7 studies (n = 318 patients) that evaluated the correlation between Ezrin and histologic response to chemotherapy and clinical prognosis (death). Data were synthesized in receiver operating characteristic curves and with fixed-effects and random-effects likelihood ratios and risk ratios. Quantitative synthesis showed that Ezrin is not a prognostic factor for the response to chemotherapy. The positive likelihood ratio was 0.538 (95% confidence interval [95% CI], 0.296- 0.979; random-effects calculation), and the negative likelihood ratio was 2.151 (95% CI, 0.905- 5.114; random-effects calculations). There was some between-study heterogeneity, but no study showed strong discriminating ability. Conversely, Ezrin positive status tended to be associated with a lower 2-year survival (risk ratio, 2.45; 95% CI, 1.26-4.76; random-effects calculation) with some between-study heterogeneity that disappeared when only studies that employed immunohistochemistry were considered (risk ratio, 2.97; 95% CI, 2.01- 4.40; fixed-effects calculation). To conclude, Ezrin is not associated with the histologic response to chemotherapy in patients with osteosarcoma, whereas Ezrin positivity was associated with a lower 2-year survival rate regarding risk of death at 2 years. Expression change of Ezrin is an independent prognostic factor in patients with osteosarcoma.

  • The purpose of this study is to investigate factors that affect corporate CEOs' tax avoidance, ultimately helping find how to fundamentally prevent the avoidance, establish a tax system that ensures tax payers' compliance and revise tax laws and regulations in a positive way. For the purpose, this researcher surveyed corporate CEOs with a questionnaire that contained many questions of various types, which was developed based on previous studies. Findings of the study can be summarized as follows. Main factors affecting tax avoidance were the application of tax provisions, the ability to understand tax laws and the expectation of tax avoidance. The more corporate CEOs' were influenced by the first and the third factors, the higher their propensity for tax avoidance was. On the contrast, corporate CEOs were lower in propensity for tax avoidance when they were more able to understand tax laws. Regarding the three factors' relative influences, tax avoidance was most affected by the expectation of tax avoidance, followed by the ability to understand tax laws and the application of tax provisions in order. Meanwhile, a multi-regression analysis using the sequential deletion technique showed that tax avoidance were affected by the application of tax provisions and the expectation of tax avoidance and that tax avoidance was most influenced by the application of tax provisions, followed by the expectation of tax avoidance. These findings indicate that the degree of corporate CEOs' tax avoidance may vary depending on social and environmental changes that their business face. Meanwhile, positive factors such as tax-bearing capacity and the procedure of tax calculation and negative factors such as management ethics and tax authorities' regulation are all thought to be not helping prevent tax avoidance.

  • For knowing the effects of aging on conversational skills in daily communication, this paper studied for the conversational turn-taking skills, working memory and naming ability on healthy elderly adults over 65 ages. 85 elderly adults participated in this study, which divided into four groups by ages. Speech samples were collected in natural conversation. Memorization of numbers, mental calculation, repetition of words were administered for working memory test. K-BNT was used for the naming ability. One-way ANOVA analysis was used for the comparison of conversational turn-taking skills among four groups. We analyzed the correlation between conversational skills, working memory and naming ability. The results were as follows: first, there were a significant difference in conversational turn-taking skills by age, but not by gender. There was a significant difference in 'Turn-Taking Frequency' and 'Total Utterance Frequency' among four groups. The same results were shown in the scores of females within three groups(exclude groups over 85D)(p<.01). Second, there was a significant correlation between 'rates of maintenance' and 'naming ability'. In addition, it was found that the naming test predicted 'rates of maintenance' skills. The results of this study suggest that word-retrieval ability will be helpful to enhance functional communication skills in aging old adults.
