  • Most existing DRM systems give too much power to rights holders and have not concerned the requirements of the consumers. In this paper, we propose a mechanism for license distribution that considers the distribution of rights between consumers. we describe the protection of digital content in two digital licenses, formal license and peer license. Also we propose an extending mechanism to control the distribution of rights between consumers. For this mechanism, we define it by extending the ODRL model in the end.

  • A multivariate statistic based on interdirection is proposed for detecting dependence among many vectors. The asymptotic distribution of the proposed statistic is derived under the null hypothesis of independence. Also we find the asymptotic distribution under the alternatives contiguous to the null hypothesis, which is needed for later use of computing relative efficiencies.

  • Purpose: This study aims to set desirable directions for Korea's egg industry by comparing and analyzing the egg distribution structure and policies between Korea and other countries. Research design, data and methodology: We analyzed the current state of egg distribution in Korea, and based on this analysis, we derived problems. In addition, by comprehensively analyzing the egg distribution structure and policy issues in the US, EU, and Japan. Results: As a result of the analysis of the egg distribution status and policy in the country to be analyzed, it was found that for the development of the egg industry in Korea, it is necessary to unify the distribution system for transparent and stable management of the egg distribution process. It was found that detailed and clear information creation and management of egg production and distribution processes were required. Conclusions: We need to establish a regional egg distribution facility base and stipulate that eggs produced in Korea must be compulsorily traded through the regional facility base. Seemingly, scaling-up of the industry is the priority, but the government is promoting various policies to expand small and medium-sized egg joint markets, with limitations in improving the problems of the existing egg distribution structure.

  • The research classifies three types of asymptotic tail distributions such as long(heavy, thick) tailed distribution, medium tailed distribution and short(light, thin) tailed distribution. The extreme value distributions(EVD) classified in this paper can be used in SPC(Statistical Process Control) control chart and reliability engineering.

  • The concepy of positive aging describles the adverse effects of age on the lifetime of units. Various aspects of this concepts are described in terms of conditional probability distribution of residual life times, failure rates, equilibrium distributions, etc. In this paper we will consider some partial ordering relations of life distribution under residual life functions and equilibrium distributions.

  • Parametric estimation of a truncated point in a right truncated Rayleigh distribution will be considered. The MLE, a bias reduced estimator and the ordinary jackknife estimator of the truncated point in the right truncated Rayleigh distribution will be compared by mean square errors. And proposed estimators of the reliability in the right truncated Rayleigh distribution will be compared by their mean squared errors.

  • We define a skew-symmetric Laplace distribution by a symmetric Laplace distribution and evaluate its coefficient of skewness. And we derive an approximate maximum likelihood estimator(AME) and a moment estimator(MME) of a skewed parameter in a skew-symmetric Laplace distribution, and hence compare simulated mean squared errors of those estimators. We compare asymptotic mean squared errors of two defined estimators of reliability in two independent skew-symmetric distributions.

  • We shall consider estimations of an exponetiated parameter of the exponentiated Pareto distribution with known scale and threshold parameters. A quotient distribution of two independent exponentiated Pareto random variables is obtained. We also derive the distribution of the ratio of two independent exponentiated Pareto random variables.

  • As we shall dene an exponentiated complementary power function distribution, we shall consider moments, hazard rate, and inference for parameter in the distribution. And we shall consider an inference of the reliability and distributions for the quotient and the ratio in two independent exponentiated complementary power function random variables.
