In this paper, we extend the medial triangle theorem and Varignon's theorem to generic two-dimensional polygons and highlight the role played by diagonals in this process. One of the results is a synthetic definition of the concept of median for an n-sided polygon.

This paper describes a shape matching algorithm for occluded or distorted two-dimensional objects. In our approach, the shape matchin is viewed as a segment matching problem. A shape matching algorithm, based on both the stochastic labeling technique and the hypothesis generate-test paradigm, is proposed, and a simple technique which performs the stochastic labeling process in accordance with the definition of consisten labeling assignment without requiring an iterative updating process of probability valiues is also proposed. Several simulation results show that the proposed algorithm is very effective when occlusion, scaling or change of orientation has occurred in the object.

The concept of six sigma was introduced at and popularized by Motorola in its quest to reduce defects of manufactured electronics products. When used as a metric, six sigma technically means having no more than 3.4 defects per million opportunities in any process, product, or service. More important than the technical definition is the concept of six sigma as a disciplined, quantitative approach for improvement of defined metrics in manufacturing, service, or financial processes. This approach derives the overall process of selecting the right projects based on their potential to improve performance metrics and selecting and training the right people to get the business results.

Concurrent behaviors of multithreaded programs cannot be described effectively by automata-based models. Thus, concurrent program intrusion attempts cannot be detected. To address this problem, we proposed the process algebra-based detection model for multithreaded programs (PADMP). We generate process expressions by static binary code analysis. We then add concurrency operators to process expressions and propose a model construction algorithm based on process algebra. We also present a definition of process equivalence and behavior detection rules. Experiments demonstrate that the proposed method can accurately detect errors in multithreaded programs and has linear space-time complexity. The proposed method provides effective support for concurrent behavior modeling and detection.

Considering our increasingly interconnected organizations heavily relying on business processes and the growing need for timely accurate knowledge to achieve greater agility in the enterprise, the idea of looking at business processes as a knowledge object is gaining momentum. Business process information is knowledge and should consequently be managed as a valuable organizational asset, particularly because organizations need to react in near real time to environmental changes and events. This paper provides an overview of the situation in this field arguing for a better definition of the intersections between knowledge and business process management. When business process is seen as knowledge, it should be managed as such. We assess and discuss some of the resulting benefits and considering the need for greater dynamic integration between the two domains, we look at ontologies as an interesting technical approach to bridging this gap showing an example for an ontology based sales order process.

The purpose of this study is to analyze the changes in contents of home management part in the home economics textbooks fur middle school from the 1st to the 7th curriculum period. The contents in the all of home economics textbooks published in every curriculum period are analyzed. The major findings of this study are as follows: 1. The part of home management is divided into seven specific areas including 'definition and process of home management', 'utilization of family resource and environment management', 'time management', 'household labor/work nanagement', 'family financial management', 'purchasing', and 'consumer protection'. 2. From the 6th curriculum period, the area of 'definition and process of home management' begun to be explained using system's approach and the area of 'household labor/work management' changed its' focus from household to self management. 3. The areas emphasized in the beginning of curriculum period were 'family financial management' and 'household labor/work management'. The 'consumer protection' ' and 'utilization of family resource and environment management' were the areas emphasized in the later curriculum period. 4. The contents of 'family financial management' area have changed very little, however, the contents of 'purchasing' area have changed a lot during the all curriculum periods. 5. The contents of illustrations, tables, pictures, and activities have changed according to changes of the contents of the textbooks.

This review paper examines various terms used for the definitions and classifications of ecosystem services, often times mixed and confused, in the literature and re-establishes the concepts of important terms, including ecosystem functions, services and benefits, to enhance communication among the stake-holders in the process of decision making. The definitions and scopes of ecosystem services are differentiated depending on the policy purposes such as environmental accounting, environmental valuation and natural resource management. The importance of identification and enumeration of final outputs associated with a particular policy is addressed. In addition, the usefulness of an alternative pathway-analysis beginning from benefits, via services and function, to process/structure of ecosystem is emphasized.

In this paper, we propose a robust blind watermarking scheme for high-definition video. In the embedding process, luminance component of each frame is transformed by 2-dimensional fast Fourier transform (2D FFT). A secret key is used to generate a matrix of random numbers for the security of watermark information. The matrix is transformed by inverse steerable pyramid transform (SPT). We embed the watermark into the low and mid-frequency of 2D FFT coefficients with the transformed matrix. In the extraction process, the 2D FFT coefficients of each frame and the transformed matrix are transformed by SPT respectively, to produce two oriented sub-bands. We extract the watermark from each frame by cross-correlating two oriented sub-bands. If a video is degraded by some attacks, the watermarks of frames contain some errors. Thus, we use an ensemble position-based error correcting algorithm to estimate the errors and correct them. The experimental results show that the proposed watermarking algorithm is imperceptible and moreover is robust against various attacks. After embedding 64 bits of watermark into each frame, the average peak signal-to-noise ratio between original frames and embedded frames is 45.7 dB.
