This study intended to find out the most substantial items in cold and heat pattern identification(CHPI) questionnaire based on usual symptoms through CHPI diagnosis and evaluation by experts. 120 participants, faculties of OO university, filled out CHPI questionnaire based on usual symptoms by the way of self-reporting. Then 2 Korean Medicine doctors independently diagnosed them whether they belonged to cold pattern identification(PI) or heat PI, and scored the result of it. Pearson correlation of 2 experts was 0.649 in cold PI and 0.605 in heat PI. Agreement was 75.8%(Kappa value 0.516) in cold PI and 74.2%(Kappa value 0.465) in heat PI. Pearson correlation of 2 experts was 0.649 in cold PI and 0.605 in heat PI. Agreement between two experts was 75.8%(Kappa value 0.516) in cold PI and 74.2%(Kappa value 0.465) in heat PI. Items of high correlation with experts' evaluation followed next: "do not usually like the cold", "usually like the warm", "usually feel cold" in cold PI and "do not usually like the hot", "usually feel hot", "usually feel burning sensation in the body" in heat PI. We could infer from that facts that experts give weight on 'subjective feeling of cold or heat in participants body' and 'preference on sensation of cold and heat'. We also expect this study to be an epidemiological foundation to disclose correlation between usual CHPI and diseases.

Purpose: The aim of this study was to evaluate the relationship between maternal periodontal disease and the health status of newborns using Apgar scores. Methods: One hundred pregnant women with periodontal disease were included in the case series and 100 pregnant women without periodontal disease were placed in the control group, respectively. The periodontal parameters of bleeding on probing (BOP), clinical attachment loss (CAL), probing depth (PD), birth weight, and Apgar scores were recorded in both groups. T-tests and Pearson's correlation coefficient were used to determine the birth weight odds ratio to analyze the relationship between the periodontal parameters of BOP, CAL, and PD on the one hand and an Apgar score of less than 7. An unpaired Student's t-test was used to analyze differences in means between the case and control groups using SPSS ver. 13. Results: The means of the ages, periodontal pocket depths, attachment loss, areas with BOP, Apgar score in the first 5 minutes and infant birth weight exhibited statistically significant differences between the case and control groups. The ratio of an Apgar score of <7 to periodontal disease was 3.14; the ratio of low birth weight risk in mothers with periodontal disease to that in mothers without periodontal disease was 2.74. Pearson's correlation coefficient revealed a significant correlation between the infant birth weight and BOP, CAL, and PD of the mother. In addition, there was a significant correlation between the Apgar score and BOP, CAL, and PD and also between the Apgar score and infant birth weight. Conclusions: The results of this study showed a significant relationship between periodontal disease and infant birth weight; in addition, there was a significant relationship between the periodontal indexes of BOP, CAL, and PD on the one hand and the Apgar score on the other.

Cable force monitoring is an essential and critical part of the safety evaluation of cable-supported bridges. A reasonable cable force monitoring scheme, particularly, sensor placement related to accurate safety assessment and budget cost-saving becomes a major concern of bridge administrative authorities. This paper presents optimal sensor placement for cable force monitoring by selecting representative sensor positions, which consider the spatial correlativeness existing in the cable group. The limited sensors would be utilized for maximizing useful information from the monitored bridges. The maximum information coefficient (MIC), mutual information (MI) based kernel density estimation, as well as Pearson coefficients, were all employed to detect potential spatial correlation in the cable group. Compared with the Pearson coefficient and MIC, the mutual information is more suitable for identifying the association existing in cable group and thus, is selected to describe the spatial relevance in this study. Then, the bond energy algorithm, which collects clusters based on the relationship of surrounding elements, is used for the optimal placement of cable sensors. Several optimal placement strategies are discussed with different correlation thresholds for the cable group of Nanjing No.3 Yangtze River Bridge, verifying the effectiveness of the proposed method.
