Background : The purpose of this study was to investigate the effects of taping on the neck rotation angle in the elderly. Methods : The twenty-eight elderly aged over 60 and twenty-seven college students participated in the study. In both groups, neck rotation angles were measured through CROM before and after taping. SPSS 18.0 was used for data analysis. Results : The results indicated that both groups showed significant increases in the neck rotation angles of the affected side after taping. However, there was no significant difference in the rotation angle of both neck regions after taping. The variation of the student group was higher than that of the elderly group after taping. Conclusion : We think that taping can be effective in balancing the neck muscles of both sides and in increasing the rotation angle of the neck.

난경(難經).유혈론(兪穴論)에 대(對)한 연구(硏究)

김영운,Kim, Young-Un 대한한의정보학회 2009 大韓韓醫情報學會誌 Vol.15 No.1

The nan gyeong(難經) is another name of hwang je pal sib-il nan gyeong(黃帝八十一難經) which is book of traditional oriental medicine that contains many medical theories. This thesis studies 'su-hyeol'(兪穴) that is recorded in the books. 1. '62th nan' contains that um-gyeong(陰經) has five su-hyeols and yang-gyeong(陽經) has six su-hyeols. 2. '63th nan' contains why Jeong-hyeol(井穴) starts at first among the five su-hyeols. 3. '64th nan' appears su-hyeol's character and explains it's reason. 4. '65th nan' discusses that some divisions of su-hyeol's character correspond with the climate. 5. '66th nan' explains the importance of 'Won-hyeol(原穴). 6. '67th nan' appears the eum-yang's character of 'Mo-hyeol'(募穴), eum-yang's character of 'Bae-suhyeol'(背兪穴), it's situation and it's pathological significance. 7. '68th nan' explains the stream of 'su-hyeol' in twelve meridians and it's symptoms of a disease. The Nan gyeong(難經) has the difficulty in it's contents and many scholars take charge of that differently. In that reason, each argument is subjectly. This thesis unites scholar's arguments of 'Su-hyeol'(兪穴) as many as possibly and investigates their differences objectively.

Statement of problems: Long-term success of esthetic restorations, depends on various factors, especially on color stability of the restorations. The color stability is affected by resin cements beneath the porcelain laminate veneers. Purpose: The purpose of this study was to comprehend the color stability of resin cements by comparing with 4 different kinds of resin cements (Choice, Variolink II, Nexus 2, Rely-X). Material and methods: Porcelain laminate disk samples were luted with resin cements. After thermocycling of each 1000, 2000 and 3000 cycle, specimens were measured by spectrophotometers and the color differences were. Results: 1. After thermocycling of 1000, 2000 and 3000cycle, color difference, $({\Delta}E^*)$ of all specimens were incresed, but were not statiscally significant differences. 2. In the Choice of A1 shade and the Nexus 2 of A3 shade, color difference$({\Delta}E^*)$ after thermocycling of 3000cycle was $incre^*ased$ significantly than after thermocycling of 1000cycle. However, other groups did not show any statistically significant differences (P<0.05). 3. After thermocycling of 3000cycle, color difference$({\Delta}E^*)$ between A1 shade and A3 shade of Nexus 2 showed statistically significant difference. However no statistically significant differences were observed in other groups (P<0.05). 4. The mean of color difference$({\Delta}E^*)$ is 1.0-2.06 after 3000 thermocycling and the data were ranked in the ascending order of Variolink II, Nexus 2, Choice and Rely-X in A1 shade group and Choice, Rely-X, Variolink II and Nexus 2 in A3 shade group. Conclusion: Above results revealed that, after 3000 thermocycing, the color difference $({\Delta}E^*)$ of experimental resin cements was within clinically acceptable ranges. Color stability of 4 different resin cements was comparatively excellent.

김영운,서해준,조태원,Kim, Young-Woon,Seo, Hea-Jun,Cho, Tae-Won 한국전기전자학회 2008 전기전자학회논문지 Vol.12 No.1

최근 급진적으로 반도체 기술이 발전함에 따라 집적회로(VLSI)의 집적도가 향상되고 있으며, 이동통신 및 멀티미디어의 발달로 많은 양의 데이터를 고속으로 처리하기 위한 대규모 프로세서들이 개발되고 있다. 전가산기는 디지털 프로세서와 마이크로프로세서에 있어 매우 중요한 요소이다. 따라서 전가산기 설계 시 전력소비와 스피드의 개선은 중요한 요소이다. 본 논문에서는 일반적인 Ratioed 로직과 패스 트랜지스터 로직을 이용하여 새로운 구조의 전가산기를 제안하였다. 제안된 전가산기는 일반적인 CMOS, TGA, 14T에 비해 좋은 성능을 나타내었다. 제안된 회로는 지연시간의 경우 기존회로의 평균값에 비해 13%우수하였고 PDP(Power Delay Product)비율은 약 9% 정도 우수한 특성을 보이고 있다. 실측 회로의 크기 평가를 위해 0.18um CMOS공정으로 레이아웃을 하고 HSPICE를 이용하여 시뮬레이션 하였다. With the recent development of portable system such as mobile communication and multimedia. Full adders are important components in applications such as digital signal processors and microprocessors. Thus It is important to improve the power dissipation and operating speed for designing a full adder. We propose a new adder with modified version of conventional Ratioed logic and Pass Transistor logic. The proposed adder has the advantages over the conventional CMOS, TGA, 14T logic. The delay time is improved by 13% comparing to the average value and PDP(Power Delay Product) is improved by 9% comparing to the average value. Layouts have been carried out using a 0.18um CMOS design rule for evaluation purposes. The physical design has been evaluated using HSPICE.

비재무적인 효과의 화폐가치화를 위한 IT ROI 평가 시스템 구축

김영운,정기원,Kim, Young-Woon,Chong, Ki-Won 한국정보처리학회 2007 정보처리학회논문지D Vol.14 No.1

IT 투자는 기업의 일반적인 투자와는 달리 직접적인 효과를 계량화하기 어려운 부분이 있기 때문에 경영자가 IT에 투자 의사결정을 내리기가 어렵다. IT 투자에 대한 타당성을 입증하기 위해서는 정보 제공자와 수혜자가 공감할 수 있는 객관적인 평가 체제의 수립과 신규 IT 투자에 대한 경제적 효과에 대한 계량적인 척도 및 측정 방법을 포함한 정량적인 분석 틀을 제시하는 것이 필요하다. 따라서 본 논문은 기존의 투자에 대한 타당성을 입증하기 위한 모델들의 장점을 수용하고 단점을 보완한 IT 투자와 그 투자에서 얻어지는 IT 효과를 분석하여 투자타당성을 입증할 수 있는 IT ROI 방법론을 개발하여 5개 업종 21개 기업에 적응한 결과를 반영한 IT ROI 시스템을 구축하였다. 이 시스템에 의해 정보시스템이 기업의 활동에 기여하는 효과에 대한 객관적인 타당성을 확보하여 IT 투자 의사결정을 도와주고, IT 투자를 보다 합리적으로 결정할 수 있어 효율적인 IT 투자가 이루어질 수 있는 체계를 제시한다. When it tomes to IT investment, it's a challenge for the management to make the right decision. Unlike investment in other business area, it's hard to measure direct cost vs. effect in IT business. To validate the investment in IT, it is required to establish objective assessment system that both provider and beneficiary of information can accept, and it is also required to suggest an assessment tool of fixed quantity that includes measuring standards and method for the economic effect of new investment. This study, therefore, has developed IT ROI Methodology that can prove investment validity by accepting the strong points of the existing models while complementing their weak points and by analyzing IT Investment and IT Efforts. It also has built an IT ROI System that reflects the methodology which is applied to 21 companies of 5 business categories. This system is designed to provide effective and objective decision-making tool for IT investment by proving what positive impacts IT could have on business activities.

김영운,이태상,김의화,이승구,Kim, Young-Un,Lee, Tae-Sang,Kim, Eui-Hwa,Joo, Yong-L.,Lee, Seung-Goo 한국섬유공학회 2007 한국섬유공학회지 Vol.44 No.5

In order to prepare neat barium titanate/silica ($BaTiO_3/SiO_2$) composite fibers, combined process of sol-gel synthesis and electrospinning was utilized. Electrospun composite fibers were subjected to the high temperature calcinations to fabricate the crystalline structure of $BaTiO_3$. The fraction of barium titanate to silica in fiber and the calcination temperature of fiber were varied. Prepared $BaTiO_3/SiO_2$ composite fibers have diameters of 500 nm to $3\;{\mu}m$ and show the neat surface morphology without any porous structure. Calcined composites fibers were characterized using powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR).
