Using the precipitation data of the sixteen stations in the south of the Yangtze River from 1955 to 2009, this paper calculated the drought index of each month and analyzed the change characteristics of the Station Proportion of Drought Frequency and the Drought Intensity based on the Standardized Precipitation Index (SPI). The results have shown that the drought tendency increased at different degrees in annual scale, and the main drought types are Spring Drought and Autumn Drought with the increasing trends on season scale. Meantime, the Summer Drought trend decreased, and the Winter Drought was considerable variation. As far as the space variation characteristics are concerned, the southwest region is the worst drought area, the southern region comes second, and the central and the eastern part are not so severe. As a drought index, SPI can well reflect a Regional Drought feature.

Aim and Objectives: The aim of this study was to determine the cephalometric skeletal and dental norm for orthognathic surgery for North Indian population using Burstone’s analysis and to test the hypothesis that there are racial and ethnic differences in cephalometric measurements between North Indian and Caucasians. Materials and Methods: A total of 120 young adults which consists of 66 males and 54 females, 18 26 years with well-balanced facial profile and minimum arch length discrepancies were chosen for the study. Lateral cephalograms with teeth in maximum intercuspation were recorded and analyzed with AutoCeph software. The mean values of cephalometric skeletal and dental variables of COGS (Cephalometrics for Orthognathic surgery analysis) analysis for North Indian males and females were compared with those Caucasians. P < 0.05 was considered to be statistically significant. Statistical Analysis: The statistical difference in the values of parameters between males and females of North Indian population was analyzed using unpair ‘t’ test whereas the difference between the study population and Caucasians was analyzed using one sample t test. Results: All the cephalometric parameters were found significantly less except convexity angle, maxillary and mandibular dental proclinations, occlusal plane angle. Maxilla and mandible was found prognathic and greater chin prominence in North Indian population compared to Caucasians. Conclusion: Significant difference in the cephalometric characteristics were found between Caucasians and North Indian population. Gender and racial/ethnic differences should be considered for diagnosis and treatment planning for orthognathic surgery for North Indian population.

How to replace the cumbersome and complicated program operation in the past through more natural human-computer interaction for the Following Robot. In this paper, Xtion Pro Live Somatosensory devices is introduced into the robot control system, and designed a kind of Following Robot based on bone identification. The full paper analyzes the overall design composition of the Following Robot and conducts experimental analysis. The results show that: On the basis of realizing target following, this robot can also recognize and execute target action, which greatly improves the maneuverability of the robot.

The diagnosis and treatment of oral premalignant lesions and squamous cell carcinoma are currently based on histopathologic features, site of involvement and stage of disease. Recent advances in techniques for detecting lesions and predicting their progression or recurrence are reviewed here. Adjuncts for detection of lesions and selection of biopsy sites include vital tissue staining (with toluidine blue) and exfoliative cytology. Advances in diagnosis and staging at the molecular level are expected to affect choice of treatment and patient outcomes. Oral health care providers should be aware of these advances in the evaluation and diagnosis of oral premalignant lesions and squamous cell carcinoma.

This study aims to examine the influence of external and internal factors on the price of the company's coal mining subsector for the period 2015-2017. The independent variable used in this study consisted of exchange rate, coal prices, inflation, DER, and ROE. The research sample consisted of 18 coal mining subsector companies. The method of analysis uses panel regression analysis. The results showed that exchange rate and coal price partially had a significant effect on the coal stock price with a 95% confidence level, ROE partially had a significant effect on the coal stock price with a 90% confidence level, while inflation and DER has no significant effect. to the coal stock price. The exchange rate, coal prices, inflation, DER, and ROE simultantly influence the coal stock price, with a determination coefficient of 10.64%.

The purpose of this study is to determine the effect of corporate social responsibility disclosure and intellectual capital elements toward corporate value, with the financial performance as intervening variable. The populations of this study are manufacturing companies listed by the Indonesia Stock Exchange (IDX) within the period of 2015-2017. Data were collected by using purposive sampling method. Based on the mentioned criteria, 53 companies were selected as the samples of this study with 159 data. The analysis data method was using descriptive statistics and multiple regression analysis with Eviews software 9 versions. The finding shows that that (1) corporate social responsibility disclosure has a negative effect to financial performance; (2) Intellectual capital elements (VACA, VAHU and STVA) have positive significant effect to financial performance. (3) Corporate social responsibility disclosure has positive significant effect to corporate value. (4) Intellectual capital element (VACA, VAHU) has no effect to corporate value while intellectual capital element (STVA) has negative effect to corporate value. (5) Financial performance has positive significant to corporate value. (6) The financial performance has mediated the relationship between corporate social responsibility disclosure and corporate value. (7) The financial performance has mediated the relationship between intellectual capital elements (VACA, STVA) and corporate value but VAHU has not mediated.
