거베라의 수경재배에 관한 연구 : 양액의 농도가 생장 및 개화에 미치는 영향 Effect of E.C on the growth and flowering
최병진 대구효성가톨릭대학교 1996 연구논문집 Vol.53 No.2
거베라의 양액재배를 위하여 생육 및 개화에 가장 적합한 양액의 농도를 조사하기 위하여 'Volga'와 'Marleen' 두 품종의 거베라를 공사하여 양액재배를 실시하였다, 양액의 농도는 E.C 1.25, 1.5, 1.75 및 2.0으로 조절하여 비순환식으로 재배한 결과 지상부의 생육은 농도가 높아짐에 따라 촉진되는 경향을 보였으나 절화의 수확량은 1.25의 경우를 제외하면 큰 차이를 보이지 않았고 품질은 1.5와 1.75의 경우가 2.0의 경우가 좋은 결과를 보였다. 이상의 결과를 보아 실제 농가의 재배의 경우에서는 양액의 조제비용을 고려해 볼 때 E.C 1.5로 조절하여 사용하는 것이 가장 적당할 것으로 생각된다. This study was conducted to confirm the optimum concentration of nutrient solution for the nutriculture of gerbera. Two cultivas, 'Volga' and 'Marleen', were used for the study. The concentrations were set to E.C 1.25, 1.5, 1.75 and 2.0. The vegetative growth was poor in E.C 1.25, but there were no significant differences among other treatments. The number of flowers and flower qualitiies were great in E.C 1.5 and 1.75 while, in 2.0, scape diameter, neck diameter and flower diameter decreased. As these results, the optimum concentration of nutrient solution for the nutriculture of gerbera might be E.C 1.5.

The term "oligodontia" or "Hypodontia", "Partial anodontia" have been uged to describe varable degrees of reduction in number of teeth. Oligodontia may occur alone or as a result of some syndrome. 13, 15years old female sister were iefered to the department of pedodontics, college of dentistry Chonbuk National University for ev3luation and replacement of absent teeth. They had no special infectious desease in their childhood. In family hystory, their mother also showed missing teeth. They had no special syndrome of ectodermal disorder except cone shape canine, notched upper central incisor. In panoramic view, multiful missing teeth were showed. For masticatory function, we restored missing area as space maintainer.

1) 鋪裝 沿邊의 公害物質이 견층비율에 큰 영향을 나타난다. 2) 春蠶, 秋蠶 晩秋蠶 飼育에 대한 公害의 影響은 매우 차가 심하여 견층 비율은 각 계절간에 다양하게 나타났다. 3) 桑園 肥培管理를 철저히하여 누에 生理에 유의하여 公害를 다소나마 防止해야겠다. 4) 綜合的인 公害 방지책을 硏究해야겠다. This study was Carried out to investigate the effect of airpollution substance on raising silkworms and the way reducing the damoge of a public nuisance. The result obtained were summarized as follows: 1. Imjury of air pollution substanel at the areaa asphalt road was increased more than Cocoon layer ratio of a hilly country. 2. As the effect of public hagard about the raising silkworms in the spring, fall and latefall showed very difference, Cocoon lager ratio was varietal to the treatment of season all. 3. I think that we must reduce the damage of air pallution as think over the silkworm physiology.

C#과 3차원 그래픽 라이브러리를 사용한 택스쳐 맵핑 기법 연구
이성진;하창수;최병윤 동의대학교 산업기술연구소 2010 産業技術硏究誌 Vol.24 No.-
To make 3D games, it requires rendering engine, animation engine, sound engine, server engine, physical engine, map editor and game artificial intelligence. Rendering engine have to support 3D object display function, objects control function for realtime object display, object animation making function, game environment control function, camera move, rotation, scaling, shrinking control function, light source and shadow control function, special effect display function, texture based special function and shader utilization. In this paper, we describe how to render models using Visual studio 2005 C#. The models are created by 3DMAX and exported as X file that represents mesh information and then texture mapped using DirectX library.

葯培養을 利用한 벼의 細胞質雄性不稔 系統에 대한 稔性回復 系統의 育成
高在哲,崔秉晉 대구효성가톨릭대학교 응용과학연구소 1994 응용과학연구논문집 Vol.3 No.-
벼 1代雜種普及에는 雜種强勢가 높고 우수한 不稔系統과 稔性回復力이 높은 系統이 준비된 후에 實用化가 기대되어진다. 本 硏究는 雄性不稔親에 대한 稔性回復親을 育成하기 위한 方法으로 葯培養을 利用한 結果이다. 1. 稔性回復遺傳子를 갖인 密陽77號, 伽倻벼를 片親으로 交雜시킨 4組合 F_1 葯培養에서 캘루스 分化率은 20∼40%, 綠色植物體 分化率은 2∼8%였다. 2. 密陽 77號 × IR20654(인디카) F_1葯培養 後代系統은 인디카 不稔親에는 60∼88%의 높은 種子稔性을 나타내었으나, 자포니카 不稔親에는 完全不稔性을 나타낸 것은 回復遺傳子를 갖인 小胞子가 雄性不忍細胞質인 WA와의 相互作用에 의하여 花粉形成의 어느 단계에서 退化된 것으로 추측된다. 3. 密陽 77號 × 密陽 74號(자포니카) F_1葯培養 後代系統은 水原304A 不稔親과는 60%以下의 部分稔性 내지 完全不稔이었고 레이메이A 不稔親과는 40%以下의 部分稔性을 나타낸 것은 遠綠交雜에 의한 雜種不稔性이 관여한 것으로 생각되며 HR1619A 不稔親과는 4系統에서 80% 以上의 높은 稔性回復力을 나타내었다. 4. 伽倻벼 × 密陽 74號F_1葯培養 後代에서 선발된 ACP5는 자포니카 不稔親인 水原304A에 80%以上의 높은 花粉稔性과 種子稔性을 보여 자포니카 1代雜種 硏究에 回復親으로 기대되었다. 5. 인디카의 回復遺傳子를 자포니카로 移轉하는데 雜種不稔性이 問題가 되나 葯培養은 雜種不稔을 제거하는데 有效할 것으로 생각되었다. In the anther culture of indica X japonica about 20-40% of callus was obtained, and 2-8% of regenerated plants were obtained. In the test-cross between Milyang 77 X IR 20654(indica type) regenerated by anther culture(polen parent) and cytoplasmic-genetic male sterility(CGMS) line, indica sterile line showed about 60-88% seed fertility. But japonica sterile line showed complete sterility. It is suggested that the microspores having restore gene were de-generated during the formative period of pollens by interaction of WA. Between Milyang 74(japonica) X Milyang 77 and CGMS line, Suweon 304A sterile line showed partial fertility(below 60%) or complete sterility, and Reimei A showed partial sterili-ty(about 40%). But in HR 1619A(indica type), 4 plants showed high fetility above 80%. Thus it might be useful as a restorer of CGMS line. Between Gayabyeo X Milyang 74 and CGMS line, Suweon 304A showed about 80% pol-len fertility and seed fertility. Thus it might be useful for the study of F1 hybrid of japonica type rice.

Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.

정전 열 접합을 이용한 Multi-Substrate Bonding
이덕중,주병권,최우범,한정인,조경익,이광배,장진,오명환 경북대학교 센서기술연구소 1997 센서技術學術大會論文集 Vol.8 No.1
We performed silicon-to-glass bonding using silicon direct bonding followed by anodic bonding(SDAB). Initial bonding between glass and silicon was caused by the hydrophilic surfaces of silicon and glass ensemble using silicon direct bonding(SDB) method. We found that the bonded specimen using SDAB process had higher strength than one using anodic bonding process only. We performed multiple layer bonding by SDAB, which is glass- silicon -glass as sandwich structure. In the silicon wafer, the (1mm x 2mm x 500μm)-sized cavity was formed by the anisotropic etching of the silicon substrate in EPW(Ethylendiamin-Pyrocatechol-Water). And, the cavity was sealed with glass wafers by SDAB method.
