But both the quantity and quality of China's rural labors' participation in off-farm employment's training is very low. This paper firstly analyzes the decision-making mechanism of off-farm employment's training and argues that the rural labors participate in off-farm employment's training is a two-stage decision-making process. The rural labors participate in off-farm employment's training depends on two conditions: one is whether the economic strength to support its participation in off-farm employment's training, the other is whether the life cycle income with training greater than the sum of the life cycle income without training and the training cost. These two conditions are indispensable. And then it analyzes the problems of off-farm employment's training of the four parties: the rural labors, enterprises, various types of training institutions and government departments. Finally, it gives the policy advice to solve the problems of the off-farm employment's training.","PeriodicalId":193276,"journal":{"name":"2010 Second International Workshop on Education Technology and Computer Science","volume":"20 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132835412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a protocol based on the PEGASIS protocol but using an improved ant colony algorithm rather than the greedy algorithm to construct the chain. Compared with the original PEGASIS, this one, PEG-ant, can achieve a global optimization. It forms a chain that makes the path more even-distributed and the total square of transmission distance much less. Moreover, in the constructing process, the energy factor has been taken into account, which brings about a balance of energy consumption between nodes. In each round of transmission, according to the current energy of each node, a leader is selected to directly communicate with the base station (BS). Simulation results have show that the proposed protocol significantly prolongs the network lifetime.","PeriodicalId":193276,"journal":{"name":"2010 Second International Workshop on Education Technology and Computer Science","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131062266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the fast development of pattern recognition and artificial intelligence technology, there are increasing safety loopholes concerning traditional 2D static CAPTCHAs, resulting in that certain malicious computer programs could launch serious program attack through breaking such CAPTCHAs. In this article, we proposal a practical and safe 3-layer dynamic CAPTCHA, originally bonding the biological vision theory with the single-frame zero-knowledge theory, ensuring it not only extremely hard to recognize each single frame, but easy to identify for humans as well. It also makes full use of disadvantages of computers in recognizing numerous moving objects from a complicated background, making it still very difficult for computer programs to break even using several frames. To verify its security, an analysis is further carried out. Moreover, the 3-layer structure makes the design of CAPTCHA more distinct, taking on high expansibility as well as plenty of room for sustainable optimization.","PeriodicalId":193276,"journal":{"name":"2010 Second International Workshop on Education Technology and Computer Science","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131054049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The detecting scheme has strong stability, high automaticity. But the detecting scheme is difficult to detect light fog, and easy to misjudge some types of clouds as fog.
