The aim of this study is to define the difference between drawings including the first image sketch and 3D modeling of architects and realised buildings that are actually built on the site. We know the obvious gap that is sometimes positive, sometimes negative. Nevertheless, it is important to exame what causes the difference between two.The contents are composed of; a conceptional definition on the drawing and it's history, and the applicative approach of modern use and the new requirement of drawings like 3D modeling, and the analysis of sight-perception that mostly bring about the difference between two.
TiO2 세라믹 전극의 광전기 화학 변환에 미치는 결정립 크기와 첨가제 ZnO의 영향
윤기현,장병규,김태희 한국세라믹학회 1989 한국세라믹학회지 Vol.26 No.2
The effects of grain size and dopant ZnO on the photoelectrochemical conversion in TiO2 ceramic electrodes have been investigated. The photocurrent increases with increasing grain size in the undoped TiO2 ceramic electrode. In ZnO-doped TiO2 electrodes, the photocurrent decreases with increasing ZnO up to 0.4 wt% due to decrease of donor concentration, and then with further addition of ZnO, photocurrent increases according to the formation of second phase. However, the photoresponse appears at wavelength of 420nm, which is very close to the energy band gap of TiO2, regardless of grain size and amount of ZnO.
방사선투과필름에서 Density Profile 을 이용한 배관의 두께 평가
이성식,장병규,김영환 한국비파괴검사학회 2002 한국비파괴검사학회지 Vol.22 No.5
내부가 비어 있거나 유체로 절반 채워진 보온 및 비보온 배관에 대해 방사선 조사 방향에 따른 투과두께와 농도 변화를 전산 시뮬레이션 하였다. 결과적으로 내부가 비어있는 배관의 경우 투과필름에서 농도 변화가 연속적이며 대칭적인 반면, 유체가 절반 채워진 배관의 경우는 방사선 조사 방향에 따라 농도 변화가 비대칭적이며 크게 달라질 수 있음을 알았다. 인공 결함을 가공한 탄소강 배관 시편을 방사선원 Ir-192로 방사선투과시험 한 뒤 농도 변화를 측정하고 이론적으로 계산한 농도 변화와 비교한 결과 산란 방사선에 의한 영향이 큰 가장자리를 제외한 부분에서는 농도 변화를 이용한 두께 평가가 가능함을 확인하였다. The computer simulation has been done for non-insulated and insulated pipes which are vacant or half filled with liquid. The simulation-results showed that the density profile on the radiograph is continuous and symmetrical around the center of pipe in the case of vacant pipe. On the other hand the density profiles are not symmetrical and depend on geometrical setting for radiography in the case of half filled pipes. Finally, experimental testing on a non-insulated carbon steel pipe with artificial notches of different depth is carried out using Ir-192 and industrial film. Comparing the measured density profile on the radiograph to the the calculated one, it has been shown that it is possible to evaluate thickness variation by measuring density profile on a radiograph.

The purpose of this study is to find out which are different in the underground passages compared with the ground. And which factors significantly influence on pedestrian in the subway. The result of this study were as follows; it showed that the spatial configuration in the underground passages is different from the ground clearly. Statistical analysis indicated that Global integration and Sign are significant factors for explaining pedestrian.

The purpose of this study is to evaluate the thin fihn dielectric made of hybrid sol, which consist of barium titanate powder, polymeric sol and other polymers. This sol will be used dielectric applied to small, thin electric passive components such as MLCC(Multi Layer Ceramic Condenser), resister, inductor. This sol is composed of mixed fine barium titanate powder and polymeric sol including Ba, Ti-precursor, solvent, chelating agent, chemical reaction catalyst, the additive sols to improve fired densification and temperature reliability. First at all, we mixed hybrid sol to be dispersed and be stabilized by ball milling for 24hrs. By spin coating method, we makes thin film dielectric on the convectional green sheet for MLCC. After heat treatments, we analyzes the structure morphology, physical, electrical properties and X5R Temperature properties.
LTCC 보호층 형성에 따른 박막 전극패턴에 관한 연구
김용석,유원희,장병규,박정환,유제광,오용수,Kim, Yong-Suk,Yoo, Won-Hee,Chang, Byeung-Gyu,Park, Jung-Hwan,Yoo, Je-Gwang,Oh, Yong-Soo 한국재료학회 2009 한국재료학회지 Vol.19 No.7
Metal thin film patterns on a LTCC substrate, which was connected through inner via and metal paste for electrical signals, were formed by a screen printing process that used electric paste, such as silver and copper, in a conventional method. This method brought about many problems, such as non uniform thickness in printing, large line spaces, and non-clearance. As a result of these problems, it was very difficult to perform fine and high resolution for high frequency signals. In this study, the electric signal patterns were formed with the sputtered metal thin films (Ti, Cu) on an LTCC substrate that was coated with protective oxide layers, such as $TiO_2$ and $SiO_2$. These electric signal patterns' morphology, surface bonding strength, and effect on electro plating were also investigated. After putting a sold ball on the sputtered metal thin films, their adhesion strength on the LTCC substrate was also evaluated. The protective oxide layers were found to play important roles in creating a strong design for electric components and integrating circuit modules in high frequency ranges.
