BSG 구조를 이용한 개선된 플로어플랜 기법

성영태,허성우 동아대학교 정보기술연구소 2007 情報技術硏究所論文誌 Vol.14 No.2

BSG(Bounded Sliceline Grid) is very efficient and effective imaginary structure for floorplan. The BSG dissects the plane into rooms associated with binary relations "right-to"and "above" such that any two rooms are uniquely in either relation. A packing is obtained through an assignment of modules on the BSG, followed by physical realization BSG-PACK. But the placement algorithm based on BSG-structure suggested in [4] may include empty space (slack) that can be removed during floorplan procedure. In this paper, we propose slack removing technique using compaction algorithm on BSG-structure. To compact a floorplan efficiently we use contour data structure. Compaction using contour structure removes the slack of floorplan for both horizontal and vertical direction. The experimental results show that our technique improves both the minimum and average area of floorplan on benchmark circuits.

許甫寧,金水泳,南泰運,徐弘三,金學權 慶尙大學校 1985 論文集 Vol.24 No.1

In this study, an easy production method of CV (Compacted/vermicular) graphite cast iron with small addition of a Ni which is known as the element of the graphitization was investigated. And so, the effects of fading (holding) time and of Ni addition after the treatments with spheroidizer (Fe-Si-Mg-Ca-Al-Ti-Ce) were also investigated. The results obtained are as follows. 1. According as Ni contents in CV molten cast iron increase, the graphite No. and CV radio were increased. And so, graphite form and the distribution of the graphite were homogenized. 2. When the addition treated with Ni, the tensile strength were increased, and the effect of fading time were decreased.

The similar results were also obtained in the analysis of the amino acid sequences. In the phylogenetic tree, the isolates clustered with the reference strains and the majority of strains originated from pig, dog, wood rat and cattle.

움직임 추정 오차 분포를 이용한 H.263 부호화기의 진보 예측 모드의 동적선택

許泰元,李根泳 성균관대학교 1998 학술회의지원논문목록집 Vol.1998 No.-

본 논문은 H263 부호화기에서 진보 예측 모드(Advanced Prediction Mode, APM)를 동적으로 적용하여 계산량을 줄이고 부호화 효율을 높일 수 있는 APM의 동적 선택(Dynamic APM, DSPM)방법을 제안하였다. 화면내에 존재하는 움직임 성분을 분석하고, 그 성격에 따라 기본 예측모드(Default Prediction Mode,DPM)와 APM을 동적으로 적용할 수 있도록 하였다. 이를 위하여 매크로 블록 단위로 추정된 각 탐색점에서의 예측 오차로 구성된 움직임 추정 오차 분포(Error Distribution of Motion Estimation, EDME)를 구성하고, 이 분포를 네 개의 영역으로 분할한 다음, 각 분할 영역의 최소 예측 오차와 매크로 블록 단위로 추정된 예측 오차와의 비를 구하여, 블록 단위의 움직임 추정을 수행할 것인가를 결정하였다. 선형 움직임이 대부분인 화면에 대해서는 DPM으로 부호화 하도록 하여, 부분적으로 예측 효율이 떨어지는 것을 막을 수 있었으며, 고정된 APM(Fixed APM,FAPM)으로 부호화 하는 경우에 발생하는 계산량을 30%정도로 줄이면서, 평균적으로 으로 부호화 된 화질과 비슷한 결과를 얻을 수 있었다. In this paper, we proposed a dynamic selection scheme of advanced prediction mode(DAPM), whish reduces computational cost and improves coding efficiency. We can select the mode between default prediction mode(DPM) and advanced prediction mode(APM) accoding to motion components in a frame dynamically. For this purpose, we defined error distribution of motion estimation(EDME) as sum of absolute difference(SAD) for each searching points. This distribution region is divided to four subregions. We calculate minimu, values in each subregions and then, we determine whether block motion estimation is performed of not depending on the results. As a result, we reduced computational complexity to 30% without degradation of image quality compared to fixed APM(FAPM) by selecting DPM for linear movement.

<P>2,6-Bis((4-hexylphenyl)ethynyl)-9,10-bis(phenylethynyl)anthracene, <B>4</B>, and 9,10-bis((4-hexylphenyl)ethynyl)-2,6-bis (phenyl ethynyl)anthracene, <B>5</B>, have been synthesized to study their electronic and photophysical properties. It should be noted that the difference between these compounds is the substitution position of 1-ethynyl-4-hexylbenzene groups into an anthracene ring. In particular, substitution in the 9,10-positions of the anthracene ring enhanced J-aggregated intermolecular interactions. Since <B>5</B> has a lower bandgap energy and more compact film morphology, it exhibited higher hole mobility (∼0.27 cm<SUP>2</SUP> V<SUP>−1</SUP> s<SUP>−1</SUP>) in thin-film transistor devices.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/orlef7/2011/orlef7.2011.13.issue-8/ol200299s/production/images/medium/ol-2011-00299s_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ol200299s'>ACS Electronic Supporting Info</A></P>

南泰運,許甫寧,徐弘三 慶尙大學校 1987 論文集 Vol.26 No.1

In this sthdy, an easy production method of CV graphite cast with iron with small adition of NI which is known as the elements of the graphitizon was inverstigated. And so, the effects of physical, mechanical and thernal properties by fading time, carbon equivalent and Ni addition after the treatments with spheroidizer(Fe-Mg), were also investigated. The results obtained from this study were as follows: 1. With an increase of carbon equivalent the CV ratio was a little increased but with an increase of addition of Ni plus Mg the graphite numbers and CV rato were greatly increased. And so, the form and distribution of graphite were homogenized. 2. With an addition of Ni the ferrire ratio were decreased and the parlite ratio were a little increased. 3. With an increase of CE and fading time the mechanical properties (tensile strength, ased. And so, in case of Mg an Ni plus Mg addition the mechanical properties were greatly increased. 4. With an incease of CE and fading time the thermal properties(thermal diffusivity and conductivity ) were increased but with addition of Ni plus Mg the thermal properties were speroidal graphite ratio. 5. For the addition of Ni plus Mg the results were obtained that the decrease of lading effect the increase of inoculation effect, the increase of CV graphite ratio.

Results : 1) The results of treatment showes that 56.25% of patients achieved clinical excellent recovery and 31.25% achieved good recovery. After compairing the DITI results before and after treatment, we found 43.75% of patients achieved excellent recovery and 43.75% achieved good recovery. 2) After compairing the FNT results before and after treatment, we found 25% of patients achieved excellent recovery and 56.25% achieved good recovery. Conclusion : 1) Acupuncture showed good results over 87.5% in clinical evaluation and 87.5% in DITI. Thermographic examination showes terapeutic effect of acupuncture treatment. 2) Acupuncture showed good results over 87.5% in clinical evaluation and 81.25% in FNT. FNT showes nerve response recovery effect of acupuncture treatment.

또 하나의 사회 : 광고에 표현된 한국적 vs 서구적 인간관계

성영신,허태균,김보경,박정선 한국방송광고공사 2006 광고연구 Vol.0 No.73

본 연구에서는 광고 비주얼에 표현된 인간관계의 문화적 차이에 따라 소비자의 심리반응이 어떻게 다른지 비교해보았다. 한국적(서구적) 인간관계를 부모 - 자녀, 온가족, 부부, 연인의 네 가지 관계유형으로 나누어 이를 묘사한 인쇄 광고물을 제작한 후, 소비자의 심리반응을 fMRI(기능성 자기 공명 영상) 기법과 설문조사 방법으로 측정하였다. 소비자는 무의식적인 fMRI 반응과 의식적인 반응 모두에서 한국적 광고보다는 서구적 광고에서 더 좋은 반응을 보였다. 특히, 광고효과의 경우 연인광고를 제외한 다른 인간관계 광고들 모두에서 서구적 광고가 더 효과적인 것으로 나타났다. 이렇게 전반적으로 서구적 인간관계 광고가 강한 신경 반응과 긍정적 광고효과를 수반하는 것은 한국인들이 상당히 서구적인 가치관을 가지고 있으며 이를 지향한다는 최근 연구결과와 일치한다. 끝으로, 본 연구결과가 갖는 크리에이티브 측면의 시사점을 제안하였다. 유형별 차이로는 연인이나 부부 광고는 무의식적 반응이나 감정반응에서 한국적인 광고가 보다 긍정적인 결과를 보이는 반면, 가족이 등장하는 광고에서는 서구적 광고가 더 긍정적인것으로 나타났는데, 이는 실험참가자가 인간관계 유형에 따라 다른 문화적 인식과 지향점을 갖으며, 이것이 광고반응에 영향을 미치고 있음을 보여준다. The purpose of the present research was to compare the psychological effects of the Korean human relations advertise(KHRA) to those of the Western human relations advertise(WHRA). The consumers’ physiological and conscious responses to the ads including visual images of Korean(vs. Western) four types of relationship - parentschildren, multi-generation family, married couple, and romantic couple - were measured by fMRI(functional Magnetic Resonance Imaging) and survey. The results revealed that consumers tend to respond more strongly and better to the WHRAs than the KHRAs. Especially, in terms of advertising impacts, the WHRAs were more effective than the KHRAs across the ads of all the three human relations except the ads of romantic couples. These results are consistent with the recent research findings suggesting the Westernizing sifts of Korean cultural values. Finally, they were discussed in the view of the implications of advertising creative tips.
