Objectives The purpose of this study was to find out whether if there is correlation between the pattern differentiation questionnaire and edema index of body composition analysis. Methods The authors obtained results of pattern differentiation Questionnaires and body composition analysis tests from 195 female patients who visited the Oriental gynecology department in Kyung Hee university Oriental medicine hospital at Gang-dong. The authors conducted correlation analysis between indicators of Body composition analysis and each part of the pattern differentiation Questionnaire. Pearson correlation analysis was performed on SPSS version 13.0 for windows. Results There was negative correlation between the Phlegm Questionnaire and right arm ECF, left arm ECF, and left arm ECW of the Body composition index. There was no correlation between Yin-deficiency Questionnaire and Body composition index. There was no correlation between Heat pattern Questionnaire and Body composition index. There was positive correlation between the Cold pattern Questionnaire and right leg ECF, and right leg ECW of the body composition index. There was no correlation between degree of edema self-awareness and Body composition index. Conclusions The result showed that each Questionnaire score has different correlation or even no correlation with Body composition index and degree of edema self-awareness. Further studies are needed for a better understanding and interpretation of the relationship between edema index on Body composition analysis and Questionnaires.

Objectives : To examine the six positions correlation[六部定位] principle that is the basis of the wrist pulse diagnosis in the Neijing. Methods : The basis for argument was established by correcting an interpretation error of the theory of chi (尺) skin diagnosis. In order to accomplish this, the annotations of Yang Shangshan and Wangbing were investigated first, after which the specific meaning and methodology of the chi diagnostic method as written in many chapters of the Neijing were examined. The evidence and reasoning for the six positions correlation[六部定位] was looked into, in relation to Wangbing's annotation of the chapter, Maiyaojingweilun. The theoretical basis of the six positions correlation was searched throughout the entire Neijing, based on the correlation between Liuhe and the six positions, the five elements inter-supporting theory embedded in the six positions correlation as a diagnosis model that integrates zhangfu and meridians/channels, and the meaning of the spacial concepts used when describing the tactile technique within the chapter. Lastly, contents related to the five zhang channels within the Neijing were reviewed, to determine whether the six positions correlation was applied in wrist pulse taking Results & Conclusions : Some interpretations of the verse on matching the positions in the Maiyaojingweilun chapter of the Neijing are erroneous, while the argument that the three positions[cun-guan-chi] cannot be found in the Neijing is false as well. The wrist pulse taking in the Neijing is precisely based on the three positions correlation that divides the cun-guan-chi positions into three, and the correlation verse in the Maiyaojingweilun chapter clearly suggests the principle of matching the zhangfu and meridian/channels to the six positions of the cun-guan-chi of both left and right.

The purpose of this study was to investigate the correlation between craniovertebral angle(CVA), age, and body mass index(BMI) in middle-aged people in their 40s and 50s. The forward head posture(FHP) was measured using a posture measuring device using a 3D sensor for 456 healthy men and women. As a result of the study, the middle-aged CVA had a high level of negative correlation with age (r=-.937; p<.01) and a very low level of positive correlation with BMI (r=.071). CVA of middle-aged men had a high negative correlation with age (r=-.932; p<.01) and a very low positive correlation with BMI. There was a correlation (r=.056), whereas, for middle-aged women, there was a high level of negative correlation (r=.939, p<.01) only with age, but had a weak (low level of negative) correlation with BMI. This study suggests that CVA has a significant negative correlation with age in both males and females however, has a weak relationship with BMI.

Stomatal traits such as stomata density (SD), aperture length (APL) and width (APW), guard cell length (GCL) and width (GCW), and distance between stomata (DIS) were investigated to identify correlation with agronomic traits for 35 Korean wheat cultivars. Flag leaf width (FLW) of Korean wheat cultivars was the widest in Ol-mil, and the narrowest in Keumkang. SD tended to be higher on the adaxial side than on the abaxial side in Korean wheat cultivars. SD of adaxial and abaxial sides was classified into a cultivar with a significantly different or not. In APL, 18 wheat cultivars showed significant differences according to leaf side, and APL of adaxial was longer than APL of abaxial in 13 wheat cultivars. In APW, 15 wheat cultivars showed a significant difference, and APW of abaxial was wider than APW of adaxial among them. In GCL, 14 wheat cultivars showed a significant difference, and the GCL of abaxial was longer than the GCL of adaxial in 10 wheat cultivars. In GCW, 10 wheat cultivars showed a significant difference, GCW of adaxial was wider than GCW of abaxial and in 6 wheat cultivars. FLW of adaxial and abaxial showed a negative correlation with GCL and a positive correlation with grain number per panicle. FLW of only abaxial showed a positive correlation with DIS. The SD of the adaxial showed a negative correlation with GCL, while the SD of the abaxial showed a negative correlation with APL. APL of both sides of the leaf showed a positive correlation with GCL, and APW of only abaxial showed a negative correlation with GLC. DIS of adaxial showed a negative correlation with tiller number (TN), while DIS of abaxial showed a positive correlation with GNP.

The hierarchical recursive local-correlation PIV algorithm with CBC (correlation based correction) method was employed to increase the spatial resolution of PIV results and to reduce error vectors. The performance of this new PIV algorithm was tested using synthetic images, PIV standard images of Visualization Society of Japan, real flows including ventilation flow inside a vehicle passenger compartment and wake behind a circular cylinder with riblet surface. As a result, most spurious vectors were suppressed by employing the CBC method, the hierarchical recursive correlation algorithm improved the sub-pixel accuracy of PIV results by decreasing the interrogation window size and Increased spatial resolution significantly. However, with recursively decreasing of interrogation window size, the SNR (signal-to-noise ratio) in the correlation plane was decreased and number of spurious vectors was increased. Therefore, compromised determination of optimal interrogation window size is required for given flow images, the performance of recursive algorithm is also discussed from a viewpoint of recovery ratio and error ratio in the paper.

This study tested the relations of schools organizational climate and teachers' job stresses, perceived by 913 teachers from 45 elementary, junior- and senior-high schools. Pearson's correlation analysis for the relations between the sub-factors of both organizational climate and job stresses and cannonical correlation analysis for the relative contribution of individual variable of organizational climate upon job stress were applied for the test. The results of Pearson's correlation analysis showed that while 'intimacy', 'esprit', 'considerations', and 'production emphasis' climate had negative correlations with job stress sub-factors, 'disengagement' and 'aloofness' climate had positive correlation. 'Student guidance', a sub-factor of job stresses, did not have statistically significant correlation with any sub-factors of organizational climate. Findings from cannonical correlation analysis showed 2 significant cannonical functions to explain the relations between the sets of variables. 'Disengagement' from organizational climate positively contributed with 'authority forfeiture' and 'dissention and conflict' of the job stresses variables.

The radar interferogram represents phase differences between the two synthetic aperture radar observations acquired in slightly different angle. The success of the radar interferometric application largely depends on the quality of the interferogram generated from two or more synthetic aperture radar data sets. We propose here to apply the wavenumber correlation analysis to the in-phase and quadrature phase of the radar interferogram. The wavenumber correlation analysis is to resolve the highly correlated components from the low correlation components by estimating correlation coefficients for each wavenumber component. Through this approach, one can easily distinguish the signal components from the noise components in the wavenumber domain. Therefore, the wavenumber correlation analysis of the radar interferogram can be utilized to design post filter and to estimate the quality of interferogram. We have tested the wavenumber correlation analysis using a Radarsat SAR data pair to demonstrated the effectiveness of

This study was to investigate if Body Mass Index(BMI) is adequate as a method of physique classification of Korean female college students. For this study 571 students were selected to examine physique classification by anthropometric index, and the correlation between the various anthropometric index and risk facters(blood pressure, triglyceride, hematocrit). The following results were obtained by this study. 1) Average age of the subjects is 19.6, height 158.2cm and weight 54.4g. 2) All anthropometric indices and body fat percentage are highly correlated (r>0.713), among them BMI shows high and significant positive correlation with weight(r=0.919) and skinfold thickness(r>0.601), but negative correlation with height(r=-0.086). 3) All anthropometric indices and body fat percentage show significant correlation with blood pressure and triglyceride. Among them BMI shows high and significant positive correlation with blood pressure and triglyceride. 4) FAT% III calculated of BMI shows significant with FAT% I and FAT% II by skinfold thickness, and high correlation with blood pressure and triglyceride. Therefore FAT% III is adequate for calculation method of body fat percentage.

This paper describes a new method of estimating the gradient of a function with perturbation and correlation. We impose a known periodic perturbation to the input variable and observe the output of the function in order to obtain much richer and more reliable information. By taking the correlation between the input perturbation and the resultant function outputs, we can determine the gradient of the function. The computation of the correlation does not require derivatives; therefore the gradient can be estimated reliably. Robust estimation of the gradient using perturbation/correlation, which is very effective when an analytical solution is not available, is described. To verify the effectiveness of perturbation/correlation based estimation, the results of gradient estimation are compared with the analytical solutions of an example function. The effects of amplitude of the perturbation and number of samplings in a period are investigated. A minimization of a function with the gradient estimation method is performed.

In this paper, we propose new beamforming algorithm which overcomes signal cancellation effect even high cross correlation existing between target and interfering signal. Using the proposed method, we show that direction of arrival (DOA) of interfering signal can be estimated using correlation matrix and the cross-correlation can be eliminated in the correlation matrix of input signal. The proposed method gives high performance enhancement compared with the spatial averaging method in our computer simulation results.
