  • Introduction: Organophosphorus pesticides (organophosphate pesticides) are being most widely used as insecticides, and thus cause poisoning cases frequently. The organophosphorus pesticides at the early stage, such as parathion and TEPP, had powerful insecticidal effects and high toxicity for both humans and beasts, and caused poisoning accidents during spraying. Although many less toxic organophosphorus pesticides were then developed, the resistance to the pesticides was acquired by insects during their repeated use, resulting in less effectiveness of the pesticides.

  • Cable-stayed bridges are structural systems effectively composing cables, main girders and towers. This bridge form has a beautiful appearance and easily fits in with the surrounding environment due to the fact that various structural systems can be created by changing the tower shapes and cable arrangements. Cable-stayed bridges are structures that require a high degree of technology for both design and construction, and hence demand sophisticated structural analysis and design techniques when compared with other types of conventional bridges.

  • The success with organic foods depends on consumer acceptance and use. Potential consumers may not even be aware of organic foods or may have the wrong perception even when aware. More knowledge could lead to increased use of organics due to the link between awareness and purchases. Briz and Ward (2009) argue that while awareness is based on consciousness, consumption requires an explicit buying commitment that should be influenced by price and appropriate measure(s) of the organic quality. These may be important attributes to consider increasing organic food consumption. ...

  • Although I’ve identified different kinds of authority, it’s possible for one person to possess several or all of them. However, most of the time, authority is distributed across team leaders. The more complex the distribution of authority is, the more planning effort you’ll need to be effective. In Chapter 16, I’ll cover how to deal with situations where you need more authority than you have. For now, it’s enough to recognize that planning involves these different kinds of power. Common planning deliverables To communicate requirements, someone has to write them down.

  • Statistical methods require very large corpus with high quality. But building large and faultless annotated corpus is a very difficult job. This paper proposes an efficient m e t h o d to construct part-of-speech tagged corpus. A rulebased error correction m e t h o d is proposed to find and correct errors semi-automatically by user-defined rules. We also make use of user's correction log to reflect feedback. Experiments were carried out to show the efficiency of error correction process of this workbench. The result shows that about 63.2 % of tagging errors can be corrected. ...
