Among them, 11 cases (73%) had symptoms relief, 3 cases (20%) tumor minimal remission and AFP decreased in 4 cases (33%). One case dide of hep'atoma 8 months after HAI-F and another case was followed up only 2 months after treatment, the remaining 13 cases are alive for 5 to 10 months after HAI-F. The reasons of unsatisfactory results were analyzed and possible ways of improvement were suggested.展开更多

The results showed that the tested variety 10-2 exhibited the highest average yield of 61 520.9 kg/hm2, which was higher than Mantian 2180 as control by 33.7%. Varieties 10-2 and 10-3 showed the advantages of good fruit type, uniform size, thick pericarp, good hardness, high fruit setting rate, strong disease resistance, good low temperature resistance, good tolerance to stor-age and transportation and good quality. They could be planted for demonstration as export varieties in open field and greenhouse in mountainous area in Ningxia.展开更多

The present regulation for Korean listed firms requires that if a company's sales revenue, operating income(or loss) and net income(or loss) have changed by over 30%compared to the prior year, the firm must disclose this information through a preliminary financial report(PFR) even before the company is audited by external auditors. To analyze the effects of this policy, we first investigate the timeliness of preliminary financial report disclosures. We examine the extent to which Korean listed companies actually comply with the requirement for prompt notification of information concerning material changes in financial performance. Second, we investigate the informativeness of preliminary financial reports by analyzing differential stock market reactions to different timings of preliminary financial report disclosures. Our empirical results reveal that more than half of our sample firms release their preliminary financialreports after external audits are completed, thereby potentially invalidating the effectiveness of the regulation. In addition, we find that preliminary financial reports have information value only if they are disclosed prior to annual audit report dates. This finding supports the notion that timeliness increases the informativeness of preliminary financial report disclosure by curbing insiders' ability to potentially profit from their information advantage.展开更多
