The paper shows the use of classic statistical methods in combination with advanced digital measurement systems in order to obtain the correlation dependencies, nature of energy consumption and opportunities for energy forecasting. The main purpose of the study is to obtain statistical dependencies of the nature of power consumption and correlations between electricity consumption and ambient temperature in order to improve the accuracy of energy planning. The analysis includes application of energy management systems for proper energy planning, improving economical efficiency and reducing power and energy losses.展开更多

Relationships between cropland changes and driving forces were qualitatively studied in most of the previous researches. However, the quantitative assessments of the contributions of climate change and human activities to cropland changes are needed to be explored for a better understanding of the dynamics of land use changes. We systematically reviewed the methods of identifying the contributions of climate change and human activities to cropland changes at quantitative aspects, including model analysis, mathematical statistical method, framework analysis, index assessment and difference comparison. Progress of the previous researches on quantitative evaluation of the contributions was introduced. Then we discussed four defects in the assessment of the contributions of climate change and human activities. For example, the methods were lack of comprehensiveness, and the data need to be more accurate and abundant. In addition, the scale was single and the explanations were biased. Moreover, we concluded a clue about quantitative approach to assess the contributions from synthetically aspect to specific driving forces. Finally, the solutions of the future researches on data, scale and explanation were proposed.展开更多

METHODS： The patients who were hospitalized in the Changhai Hospital of Traditional Chinese Medi- cine dated from March 1999 to December 2008 were included in this retrospective study. The patients were grouped according to their cancer stag- es, and their patterns were judged and quantified according to the ＂Standard diagnosis and quantitative criteria of the common patterns in primary liv-er cancer＂ formulated by the Changhai Hospital of Traditional Chinese Medicine. Statistics methods included ANOVA and nonparametric test, among others.RESULTS： The data of the 398 newly diagnosed patients showed that Qi Stagnation, Blood Stasis, and Dampness patterns were more frequent than the other basic patterns with relatively high scores; patterns of Liver Qi Stagnation, Liver Blood Stasis, and Dampness Heat were more than the other complex patterns and scored relatively high. Scores of Dampness and Liver Qi Stagnation patterns varied among the groups at different stages and the differences were statistically significant （PDampeness= 0.002, PLiver Qi Stagnation ： 0.020）. The highest scores of Damp- ness pattern and Liver Qi Stagnation pattern corresponded with Stage Ⅲ b, and Stage Ⅲ a, respectively. Dampness pattern frequency was higher （P = 0.001） in the Stage Ⅲb group than in other groups.CONCLUSION： Pattern characteristics in patients with primary liver cancer of different clinical stages might manifest in the variations of the Dampness pattern along the process of the disease and the major pathogenic factor of primary liver cancer might be Dampness.展开更多
