According to the current trend of single arm type pantograph for high speed trail korean pantograph designed to single arm type will be installed on each power car roof of prototype train of korean very high speed rail configured to 7 cars and have the characteristics of maximum 1% contact loss at 350 km/h speed. This study is devoted to design basically element components of pantograph for korean very high speed train on the basis of kinematic analysis, static analysis and dynamic analysis, followed by making the basic drawings of korean pantograph. This drawings will be complemented through certification tests of prototype pantograph and verification of analysis software.

The total length of Korean railway network is about 3,300km. Since it is of great scale in system view point, the systemization of GIS-based information system requires so much cost and time. One of the difficulties is due to the fact that GIS-based information system requires the feature database for GIS, which is generally built manually from many as-built drawing files. In order to build-up the feature database for GIS with ease, this study suggests the automatic data conversion from electronic drawings to make feature database for GIS. The proposed method can be applied to build large-scale railway facility management system at lower cost.

Numerous studies have attempted to present converting 2D drawings to 3D. However, converting 3D shapes to exactly how a person thinks is challenging because 2D drawings include numerous variables and possibilities. This study focuses on visualizing 2D to 3D in a commonly used 3D animation software required in animation education or the 3D industry. We implemented our SketchTo3D tool to add the editing and automatic texture assigning method from the imported 2D image into the 3D software that previously had to be done manually. As a result, the SketchTo3D tool saves time to immediately visualize the composition, shape, and volume to express the 3D character, providing an opportunity to break down the barrier between 2D and 3D.

자신이 느끼는 것이나 보는 것, 경험하는 것을 언어로 표현하는 것이 서툰 아동들에게 있어 미술 활동은 감정을 표현할 수 있는 방법 중 하나이며 미술 치료를 위한 중요한 분석 대상이기도 하다. PC의 그림판 기능 등을 통한 디지털 그림이 일상화된 최근에는 기존의 색채학 이론과 미술 치료 이론이 접목되고 있으며 자동 분석 기능의 필요성이 대두되고 있다. 본 논문에서는 아동이 그린 그림에 대해 주조색 분석을 하고 ART2 알고리즘을 적용하여 색채 정보를 군집화한다. 군집화된 각각의 중심 벡터값을 기반으로 색채 빈도수를 소속 함수에 적용하여 퍼지화한다. 퍼지화된 중심 벡터 값을 퍼지 추론 규칙에 적용한 후에 비퍼지화를 수행한다. 비퍼지화된 값을 분석한 후에 주조색과 보조색을 결정하여 알슈울러와 해트윅의 단일 색채에 따른 심리 상태와 색상 조합의 심리상태와 비교한 결과, 거의 비슷한 결과가 도출되는 것을 확인하였다.

Purpose: The purpose of this study is to research the revision efficiency of the referenced specifications/standards for raw and subsidiary materials in the field of national defense. Methods: Firstly, it was carried out to investigate the all of the Korean military drawings and establish the database for specifications/standards referenced in the field of national defense. Secondly, it was reviewed the validity of referenced specifications/standards of raw and subsidiary materials. Finally, proposal documents were made for invalid referenced specifications/standards of raw and subsidiary materials in order to suggest alternative specifications/standards. Results: All of the specifications/standards referenced in the Korean military drawings were 11,924 kinds and raw and subsidiary specifications/standards were 2,711 kinds. The proposal documents for revision of invalid referenced specifications/standards were suggested and approved by the military procurement standardization committee of DAPA (Defense Acquisition Program Administration). Therefore, the revision process of 472 kinds of referenced specifications/standards and 160,177 papers of the Korean military drawings were finished. Conclusion: Based on the results of this investigation, it could be significantly reduce to administrative costs and efforts through revision of referenced specifications/standards instead of conventional engineering change.

In terms of the indicators by the type for the landscape plan per the district nit, geographic ecology indicators were the items such as water, water system, topography and climate, while biological ecology indicators were the items such as green zone size, green zone ratio, biotope size and distribution. The sensory and visual indicators were the items such as view point, view axis and skyline, and the accessibility indicator items for the green zone were applied as the socially used indicators. As for the application method according to each indicator, the water or water system was expressed and applied through the slopes and elevation topographic analysis drawings, the climate was expressed and applied through the main direction of the wind and the cold wind pass alley drawings. As for the green zone size and green zone ratio, the land use according to the status and housing area development was compared to present the measured figures. In case of the biotop size and the distribution item, the range was limited to the preparation of the biotope drawings for the focused preservation. As for the view point and view axis, the view point was selected according to the view point to prepare and apply the view analysis drawing in which the view area to be preserved is analyzed. As for the skyline, its landscape photo was composed with the housing area shape, and then skyline photography was applied as the plan in order to propose and consider the various shapes of the skyline. As for the accessibility to the peen zone, the network drawing was drawn to reflect the users' accessibility and continuity of the green zone formed and preserved according to the land use plan and then the drawing was prepared and proposed as the applicable plan.
