In this paper, we propose a quantization parameter determination method for face depth image encoding in order to minimize an impact on a face recognition accuracy. When a face depth image is compressed through quantization in H.264/AVC, differential quantization parameters are assigned according to an accuracy of ellipsoid modeling prediction and an importance degree of a unit block in extracting facial features. The simulation results show that the face recognition success rates are improved by up to 6% at the same compression rates through the proposed compression rate determination method.

This research surveyed 324 college students majored dental hygiene in Gwangju and Chonnam province to analyze their awareness and degree of practice about infection control. Through the study for recognition about infectious disease related with the grade, the sophomore students are the group who is the most aware. In addition, the study shows students who experienced teeth cleaning have high degree of awareness (p<0.05). The research of perception about infectious disease based on experiences for vaccinations and education about infection prevention says hepatitis B has the highest rate when it comes to level of occurrence risk and tuberculosis and acquired immune deficiency syndrome are the lowest (p<0.05). According to the research, the group who had vaccination, knowledge about infection prevention and experience for scaling shows high practice rate for hand washing according to whether students receive protective inoculation or not. Depending on what the result were, since student learned about infection control has high degree of recognition and practice about infection management if we could emphasize the importance to students through regulative education about infection control and then increase the degree of practice, it would make big contributions to the effective infection control.

[1] and [2] present an approach to diagnosing possible defects in the mechanical systems of a nuclear power plant. In this paper, by using a fault library as a database and training data, we develop a diagnostic algorithm 1) to decide whether an Air Operated Valve system is sound or not and 2) to identify the defect from which an Air-Operated Valve system suffers, if any. This algorithm is composed of three stages: a neural net stage, a non-neural net stage, and an integration stage. The neural net stage is a simple perceptron, a pattern-recognition module, using a neural net. The non-neural net stage is a simple pattern-matching algorithm, which translates the degree of matching into a corresponding number. The integration stage collects each output and makes a decision. We present a simulation result and confirm that the developed algorithm works accurately, if the input matches one in the database.

Purpose: In this study, the research has been conducted on the health teachers and general teachers who are in charge of sexual education in the middle schools to find out their understanding on the degree of importance and degree of performance on key concept of the sex education and then compare their differences in the recognition of sex education which leads to find out the contents and range of capabilities required for the teachers in charge of sex education. Methods: A descriptive research on 77 health teachers and 71 general teachers using IPA and SPSS/WIN was practiced. Results: The result of research showed that there are significant differences in the annual hours for sex education of their schools, the contents of the sex education which was given in the lecture type lesson, and their performance degree. It was also found the distribution of key concepts by differences in IPA matrix. Conclusion: As there are the differences in the performance degree in sex education between health teachers and general teachers in middle school, more specific education for each of them is needed. And the way to reinforce the key concepts, which are found high in perceived importance degree for both health teachers and general teachers, but low in the performance degree should be considered.

The partial discharge has been blown as the chief breakdown of power equipments. The analysis and the recognition is much difficult because the partial discharge signal is very small and has complex aging pattern. Recently, insulation aging diagnosis based on pattern of phase(Ф), partial discharge magnitude(q), number(n) has been very important. Owing to depreciate the reappearance of aging progress at the electrical tree pattern and to be difficult to analyze visually, the study on partial discharge pattern is suggested to normalizing analysis method of partial discharge signals. This parer is purposed on prediction of life-time measurement of cv-cable, on decision of risk degree with normalization and real-time measurement of partial discharge signals for aging diagnosis of cv-cable. As normalizing the aging signals of electrical tree in cv-cable, it is able to confirm risk degree of insulation material with the distribution of Ф-q-n and recognize the process of aging pattern using neural network.
