Electricity theft is one of the major issues in developing countries which is affecting their economy badly.Especially with the introduction of emerging technologies,this issue became more complicated.Though many new energy theft detection(ETD)techniques have been proposed by utilising different data mining(DM)techniques,state&network(S&N)based techniques,and game theory(GT)techniques.Here,a detailed survey is presented where many state-of-the-art ETD techniques are studied and analysed for their strengths and limitations.Three levels of taxonomy are presented to classify state-of-the-art ETD techniques.Different types and ways of energy theft and their consequences are studied and summarised and different parameters to benchmark the performance of proposed techniques are extracted from literature.The challenges of different ETD techniques and their mitigation are suggested for future work.It is observed that the literature on ETD lacks knowledge management techniques that can be more effective,not only for ETD but also for theft tracking.This can help in the prevention of energy theft,in the future,as well as for ETD. 展开更多

Balancing urban and rural comprehensive reform is the major reform and developmental strategy of China. On the basis of the concept and theory of balancing rural and urban reform, the two national pilot cities Chengdu, Chongqing and several provincial pilot cities including Ningbo, Yangzhou, Shaoxing and Zigong are compared. The experiences and connotation of balancing urban and rural areas are concluded from the following four aspects. Firstly, scientific plan is a prerequisite; secondly, promoting "three collections" is the core; thirdly, developing people's livelihood is the basis; fourthly, organization security is the key. 展开更多

In Chinese language studies, both “The Textual Research on Historical Documents” and “The Comparative Study of Historical Data” are traditional in methodology and they both deserve being treasured, passed on, and further developed. It will certainly do harm to the development of academic research if any of the two methods is given unreasonable priority. The author claims that the best or one of the best methodologies of the historical study of Chinese language is the combination of the two, hence a new interpretation of “The Double-proof Method”. Meanwhile, this essay is also an attempt to put forward “The Law of Quan-ma and Gui-mei” in Chinese language studies, in which the author believes that it is not advisable to either treat Gui-mei as Quan-ma or vice versa in linguistic research. It is crucial for us to respect always the language facts first, which is considered the very soul of linguistics. 展开更多

This paper aims to study the architectural design and planning of the Egyptian nuclear research centers. Three Egyptian nuclear research centers and the proposed nuclear research center have been studied. These centers are the Nuclear Research Center in Inshas, the Hot laboratories and Waste Management Center in Inshas, the National Center for Radiation Research and Technology in Nasr City and the proposed Nuclear Research Center in North Western Coast of Egypt. Also, the paper aims to study the functions of these centers, as well as the types of their existing facilities. The paper investigates the principles and standards used in design and planning of these nuclear research centers. A comparative study has been conducted to those four nuclear research centers to evaluate the centers according to the site characteristics and the basic safety factors. The results were compared to determine the best design and planning. The proposed Nuclear Research Center in North Western Coast of Egypt proved to be the best among all with regard to design and planning, taking into consideration the radiation safety requirements. The architects are recommended to design and plan the nuclear research centers, taking into consideration the radial planning concept because it is the best with regard to radiation safety requirements. 展开更多

China has made significant progress in modernizing its healthcare system in the past 20 years. However, there are some issues that are difficult to solve on the current healthcare status, including the lack of medical care satisfaction in rural areas and urban areas, excessive consumption of medical resources, conflict and tension between the healthcare provider and patients, and the problems caused by the change of model of healthcare. Therefore, the State Council introduced the Opinions of the CPC Central Committee and the State Council on Deepening the Health Care System Reform in 2009 in order to provide basic, safe, effective, convenient and affordable healthcare for all residents. Despite the goals and policies set by the government, how to implement them remains to be challenging. Like evidence-based medicine, comparative effective research ( CER ) which started in the US in 2000 's can provide diagnosis and treatment information for patients, doctors, and health policy makers to make decisions on the effective ways of caring for both individual and population. It also may apply to the conditions of healthcare reform in China. And there are opportunities and challenges of conducting CER in our country. We suggest that the government should establish the national-level CER research institute, CER Leadership Committee and relevant standards, fund the CER projects, and begin CER in certain disciplines. 展开更多

In August 1991,the book Chinese Nation’s Traditional Sports History was published,and it was hailed as the“masterpiece of Chinese folk sports”by academic circles.In this masterpiece,the traditional horsemanship of 23 ethnic minorities and that of 10 southern ethnic minorities represented by the Miao,Yi,Bai,Shui,Hani,Naxi,and other ethnic groups has been included.For the first time,this masterpiece integrates the traditional horsemanship of the ethnic minorities in Southern China in one volume.The disadvantage is that most of the included traditional horsemanship of ethnic minorities only made a brief introduction to the time,place,and form of its development.However,under the global trend of the transition from traditional society to modern society and post-modern society,the traditional horsemanship of ethnic minorities in Southern China is facing an increasingly serious crisis of inheritance and disconnection,resulting in a gradual extinction of related traditional cultural heritage.The characteristics are gradually lost because of it.Therefore,it is essential to return to the historical and cultural field of traditional horsemanship,conduct rescue excavation,sort out the traditional horsemanship of ethnic minorities in Southern China,rescue the records of traditional horsemanship that is disappearing or undergoing drastic changes,as well as carry out comparative studies on this basis.This is not only an important way to inherit the traditional culture of ethnic minorities,but also means to protect the diversity of ethnic cultures and promote the development of exotic villages. 展开更多

Medications typically have positive outcomes, although older people are prone to drug-related problems. Community-dwelling seniors are at particularly high risk of polypharmacy, as they tend to receive many prescriptions over time and from different care providers. Continuing-care facility admission presents an excellent opportunity for a comprehensive medication review. A research study was conducted to describe and compare medications taken by community-dwelling seniors prior to and following admission to a continuing-care facility. This pilot project involved data being gathered from the charts of deceased residents, as required by a University Health Research Ethics Board, who had been cared for at one large local continuing-care facility. The facility administrators also approved this study, in part to evaluate their policy to conduct a medication review for all new residents within six weeks of entry. This study revealed a slight but statistically significant reduction in the number of medications following this review. Other issues such as medication interactions and required dosage changes were addressed by this medication review. Although this study was confined to one continuing-care facility and a small number of residents, the findings suggest medication reviews would be beneficial upon admission to all continuing-care facilities, and annually perhaps through other means for older persons living in the community. 展开更多
