Evaluation and Comparison of Marine Sci-tech Innovation Ability of 11 Coastal Provinces in China: A Case Study of Guangdong

Through building an indicator system for evaluating the marine sci-tech innovation ability of China's coastal provinces,this paper made a comparative analysis on marine sci-tech innovation ability of 11 coastal provinces in 2011-2013 by the principal components analysis( PCA) method. It found these coastal regions can be divided into three levels. Guangdong Province belongs to the first level because its marine sci-tech innovation ability is relatively high. On this basis,it analyzed changes in marine sci-tech innovation ability of 11 coastal provinces with the aid of DEA's Malmquist productivity index model. Results indicate that the overall marine sci-tech innovation ability of 11 coastal provinces is rising,but there is significant difference between provinces and the influence of regional economic development level is not considerable.Technical progress is main driver for promoting marine sci-tech innovation ability of Guangdong Province and major factor influencing ranking of total factor productivity.

INTERPOLATION METHODS FOR THE EVALUATION OF 2π-PERIODIC FINITE BAIRE MEASURE

We discuss the definition and effectiveness of a Padé-type approximation to 2π-periodic finite Baire measures on [-π,π]. In the first two sections we recall the definitions and basic properties of the Padré-type approximants to harmonic functions in the unit disk and to L p -functions on the unit circle. Section 3 deals with the extension of these definitions and properties to a finite 2π-periodic Baire measure. Finally, section 4 is devoted to a study of the convergence of a sequence of such approximants, in the weak star topology of measures.

Accurate Evaluation of China's Human Rights Legislation During the Historical Periods Before and After Reform and Opening-up

Recently, when evaluating the achievements China has made during the his- torical periods before and after reform and opening-up, Chinese President Xi Jinping pointed out, ＂The socialist construction conducted by the people under the leadership of our Party is divided into two historical periods--before and after reform and opening-up. The two periods are in- terconnected, but also different from each other. However, they both essen- tially reflect the practical explorations of socialist construction conducted by the people under the leadership of the Party. Socialism with Chinese characteristics began to take shape in the new era of reform and opening- up, but it is also grounded in New China＇s 20-plus years of experience in building and carrying out the basic system of socialism... Although the two historical periods have huge dif- ferences in the guidelines, policies,

Application of traditional indexes and adverse events in the ophthalmologic perioperative medical quality evaluation during 2010-2012

AIM: To evaluate the medical quality of ophthalmologic perioperative period during 2010-2012 in our hospital. METHODS: The relevant data of perioperative period were collected in our hospital during 2010-2012, and the medical quality of perioperative period was evaluated by using the traditional evaluation indexes and adverse events. Whereby, the traditional indicators include vision changes, improving of intraocular pressure, diagnostic accordance rate before and after operation, cure improvement rate, successful rescue rate, and incidence of surgical complications, etc Adverse events are associated with ophthalmologic perioperative events including pressure sores, postoperative wound infection, drug adverse events, and equipment related adverse events. RESULTS: There were 1483, 1662 and 1931 ophthalmic operations in our hospital in the year 2010, 2011 and 2012, respectively. From traditional index analysis, the proportions of vision improvement for each year were 96.43%, 96.76% and 97.32%, respectively; the rates of intraocular pressure improvement were 87.50%, 85.72% and 90.17%, respectively ( P <0.05); the diagnostic accordance rates before and after operation were 99.86%, 99.94% and 99.90%, respectively; cure improvement rates were 99.73%, 99.93% and 99.84%, respectively; the successful rescue rates were 82.98%, 81.46% and 76.66%, respectively; the complications incidence rates were 18.44%, 17.52% and 17.97%, respectively. The negative factor analysis results showed that: among all the patients of ophthalmic surgeries in our hospital during 2010 and 2012, only one case of postoperative wound infection was found in 2011, and also only one case of tumbling in 2010. The adverse drug events for each year were 1 case (0.07%), 2 cases (0.12%), and 4 cases (0.21%), respectively; the medical device adverse events for each year were 3 cases (0.20%), 5 cases (0.30%), and 6 cases (0.31%), respectively. Noticeably, only one case with postoperative infection of endophthalmitis was found in 2011. Moreover, no pulmonary infection or pulmonary embolism occurred during the three years. The perioperative adverse event rates for each year were 0.34% (5/1483), 0.48% (8/1662) and 0.52% (10/1931), respectively. Though incidence was rising during the three years, no statistical significance was observed (P>0.05). It is the same case with drugs and medical devices adverse events (P>0.05). CONCLUSION: Traditional indicators reflect an excellent operation of the perioperative ophthalmologic quality, whereas adverse events analysis indicates some underlying problems. Compared with the traditional indexes for medical quality evaluation, the index of adverse events is more reasonable and easier to make an objective evaluation for medical quality of ophthalmologic perioperation, facilitating further refine analysis. Reasonable application of the adverse events indicators helps hospital to make the detailed quality control measures.

Economic Evaluation Method of Photovoltaic Power Generation Installed in Ordinary Homes

This study aims to develop an economic evaluation method for installing photovoltaic power generation in ordinary homes using GIS (Geographic Information Systems). The conclusions can be summarized in the following three points: 1) This method determines the profit and loss and payback period in order to evaluate the installation of photovoltaic power generation, taking into account the price of equipment, solar battery module conversion efficiency, subsidy, electricity purchase price, service life and rate for selling electricity. 2) The proposed evaluation method was applied to Kanagawa Prefecture in Japan, providing plural scenarios. Using a solar battery module conversion efficiency of more than 15%, it is possible to make the payback period shorter than the 20-year service life and anticipate a profit in almost the whole area. 3) The areas suitable for photovoltaic power generation are Kawasaki City and Ninomiya-machi. It is necessary to adopt measures to increase the subsidy and install photovoltaic power generating systems in specific places in areas where subsidies are not provided in enough amounts.

基于主成分分析法分析不同采收期对李果实贮藏品质的影响

为探究不同采收期对李果实贮藏品质的影响,该研究以‘蜜橘’李果实为试验材料,对采后李果实13个品质及生理指标进行分析,结合主成分分析(principal component analysis,PCA)法和数学模型对3个采收期(盛花后100 d、盛花后103 d、盛花后106 d)李果实(0±0.5)℃低温贮藏品质进行综合评价。结果表明,在盛花后103 d采收的保鲜效果最好,盛花后103 d采收的李果实至贮藏结束,硬度、TA分别下降了37.37%、27.06%,下降最慢,相对电导率(relative conductivity,REL)、花青素(anthocyanidins,AC)、TSS、丙二醛、总酚(total phenols,TP)、类黄酮(flavonoids,FL)变化相对平稳,延缓了呼吸强度的上升,同时能够保持较低的多酚氧化酶(polyphenol oxidase,PPO)活性以及较高的过氧化酶(peroxidase,POD)、过氧化氢酶(catalase,CAT)、超氧化物歧化酶(superoxide dismutase,SOD)活性。经过PCA分析发现PC1、PC2和PC3可以准确地反映出87.472%的信息,这说明不同的采收期会对所有的指标产生重要的影响。通过数学模型分析可知,在盛花后100 d、盛花后103 d和盛花后106 d采收的李果实贮藏至56 d时综合得分分别为1.06、0.99和2.69,综合得分越低表明品质越好,因此保鲜效果的排序为盛花后103 d>盛花后100 d>盛花后106 d。本研究为李果实采后保鲜和品质综合评价提供理论依据,同时也为实现李果实的适时采收提供技术参数。

不同油酸含量花生品种全生育期耐旱性鉴定指标筛选和综合评价

干旱是限制我国花生产量和品质的关键环境因素之一。为探究不同油酸含量花生对干旱胁迫的反应,筛选抗旱优质花生品种,以18个普通品种和18个高油酸品种为试材,设置全生育期正常灌水和中度干旱胁迫2个处理,通过测定花生产量及其构成因素和籽粒品质指标,并结合多元统计学分析方法,对不同类型花生种质的全生育期耐旱性进行了综合评价。结果表明:全生育期干旱胁迫下,各品种的产量及其构成因素和可溶性糖含量显著降低,高油酸花生籽粒粗脂肪含量、油酸含量和油亚比显著降低,亚油酸含量显著升高,而普通花生籽粒品质并没有发生显著变化。结合逐步回归分析建立的全生育期耐旱性综合评价数学模型和灰色关联度分析结果发现,全生育期中度干旱条件下,单株产量、百果重、单株荚果数、饱果率和可溶性糖含量可作为普通花生耐旱性鉴定的指标,单株产量、百仁重、油亚比、饱果率和单株荚果数可作为高油酸花生耐旱性鉴定的指标。基于各指标抗旱系数的主成分分析、综合隶属函数和聚类分析结果,最终筛选出普通耐旱品种HY25,普通旱敏感品种FH18;高油酸耐旱品种JH16、KN71、HY665和KN1715;高油酸旱敏感品种HY52和HY951。
