  • In this paper, we propose a new adaptive dissolve detection method based on the analysis of a dissolve modeling error that is the difference between an ideally modeled dissolve curve without any correlation and an actual variance curve with a correlation. The dissolve modeling error is determined based on a correlation between two scenes and variances for each scene. First, Candidate regions are extracted by using the characteristics of a parabola that is downward convex, then the candidate region will be verified based on a dissolve modeling error. If a dissolve modeling error on a candidate region is less than a threshold that is defined by a dissolve modeling error with a target correlation, the candidate region should be a dissolve region with a correlation less than the target correlation. The threshold is adaptively determined based on the variances between the candidate regions and the target correlation. By considering the correlation between neighbor scenes, the proposed method is able to be a semantic scene-change detector. The proposed algorithm was tested on various types of data and its performance proved to be more accurate and reliable when compared with other commonly used methods

  • The purpose of this study was to investigate the structural relationships among different variables related to school adjustment. 601 elementary school students residing in Pohang-City in Korea completed questionnaires about school adjustment, internal problem behavior, external problem behavior, family adaptability and family cohesion. A variance-covariance matrix of this sample was analyzed using AMOS 19.0, and the maximum likelihood minimization function. The goodness of fit was evaluated via SRMR, RMSEA with a 90% confidence interval, CFI, and TLI. The results were as follows: First, family adaptability, family cohesion, internal problem behavior and external problem behavior were all found to have a significant direct effect how the children adjusted to their school. Second, family adaptability, and family cohesion had a direct effect on internal problem behavior. Third, family cohesion had a direct effect on external problem behavior, but family adaptability had a substantial indirect effect on the children's external problem behavior that was mediated by their internal problem behavior. Fourth, internal problem behavior had a direct effect on external problem behavior.

Methods: A descriptive correlational design was used in this study. A total of 102 patients with acute coronary syndrome was recruited. Data were collected using structured questionnaires including scales for the illness perception, the coping strategy, and health status. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and multiple regression analysis. Results: Health status showed significant correlations with illness perception (r=-.44, p<.001) and avoidance coping (r=-.33, p=.001); illness perception, avoidance coping explained 21% of variance in health status (F=8.58, p<.001). The factors that influenced health status were illness perception (${\beta}=-.37$, p<.001), and avoidance coping (${\beta}=-.21$, p<.001). Conclusion: The findings of this study indicate that illness perception and avoidance coping were significant variables for health status in patients with acute coronary syndrome who had undergone a coronary angioplasty.

  • An attemption of synthesizing and forecasting of monthly river flow has been made by employing a linear stochastic difference equation model. As one of the linear stochestic difference equation model, an ARIMA Type is tested to find the suitability of the model to the monthly river flows. On the assumption of the stationary covariacne of differenced monthly river flows the model is identrfield and is evaluated so that the residuale have the minimum variance. Finally a test is performed to finld the residerals beings White noise. Monthly river flows at six stations in Han River Basin are applied for case studies. It was found that the difference operator is a good measure of forecasting the monthly river flow.

  • The bioequivalence of two tiropramide products was evaluated in 18 health male volunteers following oral administration. Test product was Tira $m^{R}$ tablet (Shin Poong SP-102) (Shin Poong Pharm. Co., Ltd.) and reference product was Tirop $a^{R}$ tablet (Dae Woong Pharm. Co., Ltd.) One capsule of the test and reference product containing 100 mg of tropramide.hydrochloride was administered to the volunteers by randomized two period cross-over study (2 $\times$ 2 Latin square method). The drug concentration in plasma was determined by GC/MS for over a period of 12hours after administration. Analysis of variance reveal that there are no differences in AUC (area under the plasma concentration-time curve from time zero to infinity), Cmax (maximum plasma concentration) and Tmax (time to reach Cmax). The differences of mean AUC, Cmax and Tmax between two products were 3.85, 1.47 and -3.6%, respectively. Minimum detectable differences (%) at $\alpha$=0.1 were all less than 20% given as a guideline (18.07, 17.00 and 20.69% for AUC, Cmax and Tmax, respectively). From these results, the two products are bioequivalent.ent.

  • The performance of five newly evolved cross breeds were evaluated across seasons to understand the genotype and environment interactions and their stability under fluctuating tropical environmental conditions along with control hybrids $PM{\times}CSR2$ and $APM1{\times}APS8$. The data was collected on eight economic traits namely fecundity, yield per 10,000 larvae by number, yield per 10,000 larvae by weight, survival rate, cocoon weight, cocoon shell weight, cocoon shell ratio and filament length. The data was subjected for Analysis of Variance (ANOVA) and relevant statistical methods. The performance data obtained was further subjected for multiple trait evaluation index method. The ranks were adjudicated based on the index values. The two hybrids viz., $MSO3{\times}APS45$ and $MSO1{\times}APS12$ performed well under diversified environmental conditions indicating their overall stability and superiority. These hybrids revealed highly significant (p < 0.01) improvement for the majority of the traits over the control hybrids.
