본 연구의 목적은 저수지내에서 유사거동 현상 중 실제 저수지가 운영되는 조건하에서 소류사가 어떻게 거동하는가를 대표적인 소류사 공식을 통해 분석하고자 한다. 이를 위해 소류사 모의시 적용되는 하류단 경계조건 즉 저수지 수위와 저수지내 소류사 퇴적형상과의 관계를 모의할 수 있도록 대표적인 소류사 공식을 이용한 유사해석모형을 개발하고 분석하였다. 본 연구에서는 비교적 규모가 큰 다목적댐을 대상으로 과거의 저수지운영 실적을 근거로 하류 단 경계수위와 홍수량에 대해 일단위 평균자료를 적용하여 소류사를 모의하고 그 소류사의 퇴적 형상이 저수지 종단상에서 1차원적으로 시간에 따른 어떻게 거동하는 가를 고찰하였다.

Objective : This study was designed to report the clinical effect of Rectal Injection therapy on chronic prostatitis. Methods : We analyzed 20 manuscripts contributed to the Chinese medical journals from 1999 to 2003 that presenting report of Rectal Injection therapy on chronic prostatitis. Results : The results are summarized as follows 1. Operation of rectal injection therapy was treated 2~3 times and one course take time 5~30 days. 2. During therapy, average amount of fluid is 100~150 ml and it takes 1~2 hours. 3. Using medication was 'chung-yol' medicine, 'hwal-hyul-gu-er' medicine, 'bo-yik' medicine, 'lee-soo-sam-sup' medicine. Conclusion : We conclusion that Rectal Injection therapy was clinical effect on chronic prostatitis.

Objective : We performed this study to understand the trend of recent medical treatment on chronic prostatitis. Methods : We analyzed 20 manuscripts contributed to the Chinese medical journals from 1998 to 2004 that presenting report of recent medical treatment on chronic prostatitis. Results : The results are summarized as follows 1. In clinical cases, we investigate the cause of chronic prostitis was 'ha cho sup yol' 'ki wool' and 'hyul er'. also it combined complex causes. 2. Deep stimulation acu-therapy near prostate was more effective than other acu therapy. 3. External medical treatment was very efficient than other therapy that was rectal injection therapy, fumigation therapy etc. Conclusion : We conclusion that Rectal Injection therapy was clinical effect on chronic prostatitis.

X-ray lithography is one of the most powerful processes in the fabrication of nano/micro structures with a high aspect ratio. This process enables the fabrication of ultra-thin barrier ribs for PDP using X-ray sensitive paste. In this paper, organic material including photo-monomers, photo-oligomers, binder polymer and additives as well as inorganic powders with different size were optimized to fabricate high aspect ratio barrier rib pattern for PDP.

Zinc oxide (ZnO) is typically highly doped n-type semiconductor. To be used for thin-film transistor (TFT) devices, carrier concentration must be controlled precisely. We studied characteristics of ZnO grown by MOCVD at temperatures between $200^{\circ}C$ and $400^{\circ}C$. We found that hydrogen incorporated during growth plays important role in determining carrier density.

We have characterized the previously undescribed parameters for engineering the electrical properties of single-walled carbon nanotube (SWCNT) films for technological applications. The surface tension of the top coating passivation material and matching coefficients of thermal expansion for the substrate and carbon nanotube network are two crucial parameters for the fabrication of reliable and highly conductive single-walled carbon nanotube network thin films.

We present a simple process for the fabrication of high performance transparent conducting films that contain single-walled carbon nanotubes (SWCNTs) noncovalently coated with an ultrathin titania layer. The hydrophobic interactions between nanotube surfaces and the acetylacetone (acac) ligands used to stabilize the $TiO_2$ precursor provide an interesting alternative method for noncovalently coating the SWCNTs with a titania layer. The ultrathin titania layer on SWCNTs prevented the oxidation of functionalized SWCNTs at high temperatures, and protected against water molecule absorption.

We present facile chemical route stabilizing dispersion of carboxylated single-Walled carbon nanotubes (SWCNTs) in ZnOsol prepared by using diethanolamine as a stabilizer. The dispersion was stabilized via capping of carboxyl groups on the SWCNT surface by a titania layer. We also demonstrated that the conductivity of the films prepared P3/$TiO_2$/ZnO as enhanced by therml treatment, and the thermal stbility of the film improved hybridization with ZnO sol pristine P3, P3/$SiO_2$ and P3/$TiO_2$ hybrid films.
