The objective of this study is to suggest modified Covariance Structure Analysis that combine with existing Multivariate Statistical Method which is used Casual Analysis Method in Management Information. For this purpose, we'll consider special feature and limitation about Correlation Analysis, Regression Analysis, Path Analysis and connect Covariance Structure Analysis with Statistical Factor Analysis so that theoretical casual model compare with variables structure in collecting data. A example is also presented to show the practical applicability of this approach.

약 20년 전부터 시작된 한국의 극지 연구를 통해 많은 극지 데이터가 생성되었으나 대부분의 데이터들은 연구자 개인이 보유한 상태에서 체계적인 관리가 되지 않아 시간의 경과에 따라 귀중한 극지 데이터들이 유실되고 있는 실정이다. 이 연구에서는 극지 연구 분야와 극지 데이터, 해외의 극지 데이터 수집 사례의 연구와 국내에서의 극지 데이터 수집 방안에 대해 소개한다.

The purposes of this study were to examine the purchasing and using behaviors of cosmetics according to women's consumption propensity. A self administered Questionnaire was used and the subjects were 600 women of 20s and 30s in Jeonbuk Province. The data collecting periods were July, 2003. Means, percentages, and frequency were calculated. And factor analysis, cluster analysis, one-way ANOVA, and Chi-square test were done by use of SPSS PC (Ver. 10.0).

Many Safety training up to now has been done at site varying with their condition without any standardization or fundamental work related technique. In order to prevent any accidents from construction site, now as we all know, we have to approach on it with work based method. The authors have investigated a couple of construction site for collecting the ideas from site Engineers of this. Some of ideas analyzed with the above related data have been shown as conclusions.

This paper presents tile efficient polling architecture for simple network management protocol (SNMP). Now a day, tile internet traffics have been increasing rapidly within a few years as the subscriber's network to connect internet is provided commonly. With this trend, the network management traffics also make the same phases. To provide numerous higher Quality services to the customers, the management traffic must be controlled within the permitted limit. This paper proposes the policy-based felling architecture for SNMP MIB with several parameters and suggests the data collecting layer architecture for the efficient polling.

Today, L.P. model has often been used in solving economic and managemental phenomena. But in case of adopting L.P. model in dealing with practical economic and managemental problems there is a possibility that we have difficulties in solving these problems because of greatness of model size, cost for collecting data, cost for adjusting matrix, and etc. In this respect "Decomposition Algorithm for L.P." has been used in overcoming the difficulties above stated. In this paper therefore, I will try to introduce and them criticize Dantzig -Wolfe's "Decomposition Method" and Kornai - Liptak's "Two - Level Planning".ot;Two - Level Planning".uot;.

Collecting data in wireless sensor networks in minimum time is a traditional problem which is known NP-hard. Previous studies built the schedule using the node-based or link-based metrics to prioritize the transmissions. In this work, we combine the effect of both metrics to obtain a smaller aggregation time. We compare our work with state of the art schemes and report the improvement.
