The purpose of this paper is to study indefinite Kaehlerian metrics with vanishing conformal curvature tensor field. In the first section, a brief summary of the complex version of indefinite Kaehlerian manifolds is recalled and we introduce the conformal curvature tensor field on an indefinite Kaehlerian manifold. In section 2, we obtain the theorem for indefinite Kaehlerian metrics with vanishing conformal curvature tensor field.

This paper presents an evaluation criteria of an information system availability for guaranteeing availability (service target level) from the perspective of the SLA contract and its technical point of view. In order to verify the effectiveness for information system failure and availability guarantee measures, three cases were examined. In summary, the failure time was reduced by 32% ~ 62% after applying the availability guarantee measure, verifying the excellence in the evaluation of an information system availability.

The Korean Federation of Education Association has published "Vacation Life" to promote self-teaching of middle school students during the summer and winter vacation of middle school students every year. The book include whole subjecy offered in the middle school. However subject of science(Physics, chemistry, biology and earth science) is more emphasized. This article described brief summary of the contents of biology branch published in winter "Vacation Life", 1980 and summer "Vacation Life" 1981.

In this paper, we summary known suggestion system which is useful a small and medium enterprise. We don't think suggestion system of a small and medium enterprise active. We reflect 2 points of suggestion system. We propose the Active Plan to Suggestion System for small and medium Enterprise which are (1) suggestion direction for enterprise future, (2) suggestion body for all employee included, (3) suggestion methods for all information shared.

Internet communication network quality characteristics are analyzed using Beta probability distribution. Beta probability distribution is chosen for the underlying probability distribution because it is an extremely flexible probability distribution used to model bounded random variables. Based on the fitted Beta probability distribution, a dataset regarding each network quality characteristic is summarized concisely.
