To develop the content and form of the teacher education program for mathematical excellence, we reviewed several teacher education programs. CGI is an excellent model for teacher education program for mathematical excellence. We developed the 12 teacher education programs based on mathematical tasks developed for the gifted children and have applied them to teacher education. It is not so difficult to develop more programs, because we have made a lot of tasks for the gifted in mathematics for 8 years. Wooden Die for Drinking Game which is one of 12 programs is introduced in this article.

In this paper we review a bi-aspect nonparametric test for the two-sample problem under the location translation model and propose a new one to accommodate a more broad class of underlying distributions. Then we compare the performance of our proposed test with other existing ones by obtaining empirical powers through a simulation study. Then we discuss some interesting features related to the bi-aspect test with a comment on a possible expansion for the proposed test as concluding remarks.

This study reviews several well-known control charts for the location parameter with a discussion of the relationship between the maintenance of the control chart and a series of hypotheses testing. As a by-product, we then propose a new median control chart with the sign test statistic. We also modify the nonparametric control charts to easily understand the relation. Then we illustrate the construction of several median control charts with the industrial data and compare the efficiency among several control charts. Finally, we discuss some interesting features for the median control charts as concluding remarks.

This study proposes a modified definition about $C_{pk}$ based on median as the centering parameter in order to more easily control the process since the mean does not represent any quantile of the asymmetric process distribution. Then we consider an estimate and derive the asymptotic normality for the estimate of the modified $C_{pk}$. In addition, we provide an example with asymmetric distributions and discuss the estimation for the limiting variance that are followed by some concluding remarks.

Arginase was purified to homogeneity from Schizosaccharomyces pombe. The purified enzyme is a tetramer with a subunit molecular weight of 42,000. Activity is optimal at pH 10.0 and at $60^{\circ}C$ The enzyme migrated during isoelectric focusing showing a pl=5.4. The enzyme exhibited hyperbolic kinetics at pH 10.0 with an apparent $K_m$ for L-arginine of 18 mM. Arginase activity was strongly inhibited by L-glutamate.

A Bayesian burn-in procedure is developed for imited failure populations in which defective items fail soon after they are put in operation and non-defective ones never fail during he technical life of the items. Sequential schemes guaranteeing pre-specified outgoing quality of a product are derived based on prior information on the quality of a product and accumulated failure information up to the decision point. A numerical example is also provided.

대학생의 취업이 매우 어려운 시점에서 기업의 구인 요구 조건을 분석해보고 대학생이 희망하는 구직 조건을 분석하여 상호 균형적인 조건을 달성하기 위해 노력해야 할 것이 무엇인지 연구를 통해 알아보았다. 일반적으로 구인구직 과정에서 결정적 변수로 가장 중요하게 대두되는 연봉의 차이가 커 향후 대학생들의 연봉 희망 조건의 변화가 요구된다. 그렇지만 기업이 요구하는 인재 요건에서는 대학생들이 중요하게 판단하는 기준과 일부 일치하였다.

대학의 취업 정책은 졸업자의 취업지원을 위해 다양한 프로그램을 준비하야 대학생 취업을 지원하고 있다. 그러나 대학의 취업정책의 의도, 추진 성과, 준비성 등과 대학생이 인지하는 만족도, 효용성 등 부문에서 일부 차이를 보이고 있다. 이는 정책의 효과에도 문제가 있지만 정책 추진의 효율성도 떨어져 예산 낭비로 이어지고 있다. 본 연구는 이러한 대학 취업 정책의 효율성과 효과성을 높이기 위해 대학 정책에 대한 대학생의 인지도, 활용도, 만족도 등을 분석하여 대학 정책의 수정을 제시하고 있다.

This study was conducted to investigate what to consider for active response in the intrusion detection system, how to implement active response, and 6-phase response models to respond actively, including the active response scheme to detect unknown attacks by using a traffic measuring engine and an anomaly detection engine.

The influence in fitting an equicorrelation model is investigated using the influence function. The influence functions for the model parameters are derived and its sample versions are used for investigating the influence of observations on the estimators of the parameters. Some relationships among the sample versions are found. We will derive a measure for identifying observations that have a large influence on the test of fitting the equicorrelation model using the influence function method. An example is given for illustration.
