Image segmentation is an essential preliminary step in pattern recognition and scene analysis problems. Thresholding is a fundamental approach to segmentation that utilizes a significant degree of pixel popularity or intensity. Otsu's thresholding is one of the most well-known methods proposed in the literature. In the Otsu's method, the normalized histogram was employed as a discrete probability density function and a criterion of maximizing the between-class variance of pixel intensity was utilized to choose a threshold value for segmentation. In this paper, first of all, we simplify the between-class variance by which we can easily compute the criterion. Then, we propose a simple thresholding method for finding multi-level threshold values by extending the Otsu's method. Our experimental results how a possibility that the proposed method could be used efficiently for image segmentation.

Among the facial components, the eyes play an important role in recognizing human faces. This paper proposes an effective method of detecting the eyes from facial images, where the detection is carried out two steps. First of all, eye-windows(EW) containing the eyes and eyebrows are extracted with the vertical/horizontal projections. After then, the positions of the eyes are detected by applying the normalized cross correlation (CC)method to the eye window extracted in the first step. While searching the EWs, we have took smoothing firstly to reduce influence of noise and sharper bounds. From the experimental results tor the well-known face databases, we have confirmed a possibility that the proposed method, which is hierarchically combined with EW and CC in sequence, could be available one for appearance based face retrieval.

Abstract - In this paper, we implemented and investigated a sign-language communication system among Korean, Chinese, and Japanese as an extension of the sign-language communication system between Korean and Japanese. Using the system, the deaf-mute can chat each other with sign-language among the three country having different languages on the Internet. Additionally, a translation of sigh-language enables the people with different languages to communicate each other. The system employed the client-server architecture, where the client inputs the sentence by keyboard, and sends it to the server. Then the server translates it into target sign-language parameters and returns them to the group of clients. Finally, the client re-generates the sigh-language animation with the received parameters. At that time, we have used a translation table of language patterns to translate each other among different language structures.
중국 초등학생이 지각한 부모의 양육방식과 동생에 대한 수용성의 관계에서 자존감과 자기애의 매개효과

본 연구는 중국 초등학생이 지각한 부모의 양육방식이 동생에 대한 수용성에 영향을 미치는 관계에서 자존감과 자기애(외현적 자기애와 내현적 자기애)의 매개효과를 검증하였다. 이를 검증하기 위해 중국 산서성(山西省) 진중시(晋中市)에 소재한 7개 초등학교에서 5, 6학년 학생을 대상으로 설문조사를 하여 동생이 있는 666명 학생의 응답을 토대로 경로 분석을 하였다. 연구결과, 첫째, 자존감은 부모의 민주적 양육방식과 동생에 대한 수용성의 관계에서 부분 매개하고, 허용적 양육방식과 동생에 대한 수용성의 관계에서 매개하지 않으며 권위주의적 양육방식과 동생에 대한 수용성 관계에서 완전매개하는 것으로 확인되었다. 둘째, 외현적 자기애와 내현적 자기애 모두 부모의 민주적 양육방식과 동생에 대한 수용성의 관계에서 부분매개 하고 허용적 양육방식 및 권위주의적 양육방식과 동생에 대한 수용성의 관계에서는 완전매개하는 것으로 확인되었다. 따라서 중국 초등학생이 부모의 양육방식을 민주적으로 지각할수록 자존감과 외현적 자기애를 높이고 내현적 자기애를 낮춰 동생에 대한 수용성을 높이는 것을 확인하였다. 이러한 결과를 바탕으로 초등학생의 자존감과 외현적 자기애를 높이고 내현적 자기애를 낮추는 측면에서 동생에 대한 수용성을 높이는 중요성을 제시하고 논의하였다. This study examined the mediating effects of self-esteem and narcissism (external narcissism and internal narcissism) in the relationship between parental parenting style and sibling acceptance among elementary school students in China. To verify this, a questionnaire survey was conducted in 7 elementary schools in Jinzhong city, Shanxi province, China, and a path analysis was conducted based on the responses of 666 students with younger siblings. The results of this study are as follows: first, self-esteem had a partial mediating effect on the relationship between democratic parenting style and sibling acceptance, and did not have a mediating effect between the permissive parenting style and sibling acceptance. while it had a completely mediating effect on the relationship between authoritarian parenting style and siblings acceptance. Second, both external narcissism and internal narcissism had a partial mediating effect on the relationship between democratic parenting style and sibling acceptance, and had a completely mediating effect on the relationship between permissive parenting/authoritarian parenting style and sibling acceptance. Based on these results, the importance of enhancing the acceptance of siblings in terms of enhancing self-esteem, external narcissism and lowering internal narcissism was suggested and discussed.

Aero-engine blades often fracture failed due to resonance. In order to analyze the vibration characteristics of high-speed rotating blades of aero-engine more accurately, not only the out-of-plane deformation and in-plane deformation, but also the in-plane deformation caused by out-of-plane deformation are taken into account in the process of research on the rigid-flexible coupling dynamics of blade. The study using the hypothetical modal method to describe the deformation of the blade and using the Lagrangian dynamics equation to establish the first-order approximation coupled dynamics equation of the flexible blade with threedimensional large displacement motion. The simulation results show that the theoretical results of the first approximation coupling model are consistent with the actual results, but the zeroorder approximation coupling model is flawed when the blade speed is high. Based on the firstorder approximation coupling model, the vibration frequency, frequency-steering and modeswitching problems of the blade are analyzed, and the feasibility of the proposed method is verified.
