건설공사 공정 공사비 통합관리시스템(EVMS, Earned Value Management System)에서 대부분의 정보들은 공사정보 분류체계(WBS, Work Breakdown Structure)를 중심으로 활용된다. 즉, 공정편차와 비용편차 등의 EVM 성과정보 역시 WBS에서 선택된 공종을 중심으로 결과물이 분석되므로, EVMS에서 WBS는 정보중심 역할을 하게 된다. 본 연구에서는 WBS 정보가 4상한의 좌표방식으로 표현되어 프로젝트의 대 중 소 공종이 용이하게 표현될 수 있는 좌표식 공사정보분류체계(WBS Map) 표현기법을 구축하였다. 또한 연구에서는 WBS Map에 근거한 EVMS를 개발하였으며, 개발된 EVMS에서는 각종 속성 지표값들을 색상기호 등으로 시각화하는 방법론을 구축하여 EVMS 정보의 실무 활용성을 높일 수 있도록 하였다.

A Project planning is one of the most important processes that determines success and failure of the project. Scope management for project planning is also essential job in system integration project. However project planning is very difficult because lots of factor and their relationships should be considered. Therefore project planning of SI project has been done by project manager s own knowledge and experiences. It is necessary to develop an algorithm of WBS(Work Breakdown Structure) identification & document selection along to project's specificity in project management system using AI technique. This study also present method (ODW model) to cope with the limitations of the existing study that has uniformly customizing the methodology by only project complexity. We propose PPSM(Project planning support module) that apply Rule for determination of route map and document level, and CBR for WBS identification.

A technical road map is one of critical research methods which include mid/long term strategies and objectives. There are many of projects conducted using this road map. A technical tree is used at the step of planning of the projects. This research was aimed at reviewing previous systems for conducting researches for and a basis required for improving railway safety in the future by finding out inconsistency arising from physical WBS, which is methodology of defining in existing railway technical trees. In the process of this research, we considered differences between systems safety and prevention as well as natures of them using the established technical tree, and set up plans for improving technical tree to secure railway safety as an integrated system.

The purpose of this research is to analyze the shape of gathered skirts made by different gatherings. The shape of gathered skirts is affected by the amount of the gatherings that control fullness along a waistline seam. The gap also has an effect on the shape. We made a few experiments to make gathered skirts in different gathering conditions. The conditions include two types of ratio of gathers, which were given the total amount of gathering, and two types of spread of gathers, which were calculated for waist and hip. Experiments were conducted to figure out the dressed shape through 3-D measurement Exyma- WBS, and also to investigate the proportion, area distribution, and gap of the shape of gathered skirts on the horizontal section map with Rapid Form 2004 SP3, a software for 3-D shape analysis. As the results show, there were differences among the proportion, area distribution, and gap of the dressed shape. It showed that the shape on the horizontal section map was different because the shape between waist and hip per parts on body was not the same.

The purpose of this research is to analyze the lower part of dress forms with different sectional rotation-angles ($e.g.\;9^{\circ},\;15^{\circ},\;30^{\circ},\;45^{\circ}$) using three-dimensional measurement system and to investigate measurement properties for dress making. The dress forms used in this experiment were size 8 and six types: four from Korea and two from Japan. The instrument and tools for three-dimensional measurement was Whole Body 3D scanner (Exyma-WBS2H). The analysis program used in this experiment was Rapid Form 2004 PP1 (INUS technology, Inc, Korea). The measurement of dress forms was done three times with different sectional rotation-angles and its data were analyzed using SPSS WIN 10.0 Package. The following results were obtained: 1. With mean and standard deviation of each measured part, it was found out that the dress forms from two countries were different in size per each part. For example, the Japanese one was relatively large in middle hip and hip, compared to the Korean one. 2. The 3D analysis of the sectional rotation-angles revealed some differences between the two dress forms in sectional length per each part. 3. With cluster analysis results, it was found that there were definite differences among measurements per each part, especially in $30^{\circ}\;and\;45^{\circ}$ sections. 4. The proportion of the dress forms showed significant differences in the curvature between center and side section of the lower parts. In addition, the shapes on the horizontal section map of the four levels (waist, middle hip, hip, and bottom) were analyzed.
