현대와 전통의 교착(交錯)과 융합 : 漫說: 조선족 작곡가 權吉浩의 음악창작
가오, 웨이 지 漢陽大學校 音樂硏究所 1993 音樂論壇 Vol.7 No.-
7년 전, 내가 제4차 전국음악작품 콩쿨 평심위원으로 있었을 때, 처음으로 조선족 청년작곡가 권길호(권길호)의 작품을 듣게 되었다. 그때 상해음악학원의 이름없는 작곡과 학생이었던 권길호가 보내온 작품은 피아노 조곡 「장단의 조합」이었다. 「장단의 조합」,(중국인들에겐 "장단"이란 단어가 길고 짧음으로 밖에 이해되지 않는다-번역자)이 괴상한 표제의 곡을 받아 보면서 처음엔 모두들 "선봉파"식의 추상적인 작품이 아닌가고 생각하였다. 사실 이 작품은 농후한 조선족 음악쟝르와 민속적인 정감이 차 넘친 아름다운 곡이었다. 그 당시 이 작품은 청년 피아노연주가 리건의 현장연주 후 강렬한 반응을 일으켰는데, 전체 평심위원들과 관람자들을 번쩍 놀래웠다고 보도되었다. 하여 이 작품은 그번 콩클에서 제일 첫자리로 수석 1등상을 타게 되었고, 그때로부터 권길호(권길호)라는 이 이름을 기억하게 되었다.

Separation of dimethyl carbonate/methanol azeotropic mixture by using pressure-swing distillation processhas been a hot-point in the study of the synthesis process of dimethyl carbonate by urea methanolysis method. Thisstudy updates the work of the writers (Ind.Eng.Chem.Res,2013,52,11463-11478), which explores the dynamic controlstructure of the three-column separation dimethyl carbonate (DMC)/methanol (MeOH) process from an actual pilotplant. At first, the conventional DMC/MeOH separation process in the pilot test of the DMC synthesis process throughalcoholysis of urea was described in detail. Then an optimized control structure for the entire DMC/MeOH separationunit was obtained by implementing a general heuristic design procedure. An economic analysis was performed to evaluatethe optimized process. Finally, three dynamic control schemes were proposed and evaluated with several large disturbances,an improved control scheme CS3, using the multiplier blocks “QR1/F1” and “RR1” in T1, “QR1/F1” and “R/F”in both T2 and T3, outperformed CS1 and CS2 by maintaining the product specification in each column.
The Strategic Impact of the Summer Palace on China′s ″Silicon Valley″
Gao, Da-wei Korean Institute of Landscape Architecture 2001 Journal of the Korean institute of landscape archi Vol.1 No.-
The Haidian Garden of Zhongguancun Science and Technology Zone is an area with high intellectual intensity. It is therefore known as China's Silicon Valley. The Summer Palace, a World Heritage Site, sits in the northwest part of it. 250 years ago, the construction of imperial gardens in this area, including the Summer Palace, gave birth to the appearance and prosperity of the town of Haidian. This will also provide various opportunities for the growth of the science and technology. Today the green space, the cultural and ecological environment of the Summer Palace, and its 3-kilometer buffer zone are becoming one important strategic factor for the Haidian Garden to attract talents, improve international competitiveness and realize sustainable development. How to taking advantage of the favorable resources, to achieve balance between protection of the environment around the Summer Palace and urban development, will be of great importance in the future plans of the science and technology.

We adopt the PASTEL catalog combined with SIMBAD radial velocities as a testing standard to validate the stellar parameters (effective temperature $T_{eff}$, surface gravity log g, metallicity [Fe/H] and radial velocity $V_r$) from the first data release (DR1) of The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. After applying data reduction and temperature constraints to the sample obtained by cross-identification, we compare the stellar parameters from DR1 and PASTEL. The results show that the DR1 results are reliable under certain conditions. We derive a dispersion of 110 K, 0.19 dex, 0.11 dex and $4.91kms^{-1}$ in specified effective temperature ranges, for $T_{eff}$, log g, [Fe/H] and $V_r$ respectively. Systematic errors are negligible except for those of $V_r$. In addition, for stars with PASTEL [Fe/H] < -1:5, the metallicities in DR1 are systematically higher than those in PASTEL.

<P>Drug-resistant tuberculosis (TB) has lent urgency to finding new drug leads with novel modes of action. A high-throughput screening campaign of >65,000 actinomycete extracts for inhibition of <I>Mycobacterium tuberculosis</I> viability identified ecumicin, a macrocyclic tridecapeptide that exerts potent, selective bactericidal activity against <I>M. tuberculosis</I> <I>in vitro</I>, including nonreplicating cells. Ecumicin retains activity against isolated multiple-drug-resistant (MDR) and extensively drug-resistant (XDR) strains of <I>M. tuberculosis</I>. The subcutaneous administration to mice of ecumicin in a micellar formulation at 20 mg/kg body weight resulted in plasma and lung exposures exceeding the MIC. Complete inhibition of <I>M. tuberculosis</I> growth in the lungs of mice was achieved following 12 doses at 20 or 32 mg/kg. Genome mining of lab-generated, spontaneous ecumicin-resistant <I>M. tuberculosis</I> strains identified the ClpC1 ATPase complex as the putative target, and this was confirmed by a drug affinity response test. ClpC1 functions in protein breakdown with the ClpP1P2 protease complex. Ecumicin markedly enhanced the ATPase activity of wild-type (WT) ClpC1 but prevented activation of proteolysis by ClpC1. Less stimulation was observed with ClpC1 from ecumicin-resistant mutants. Thus, ClpC1 is a valid drug target against <I>M. tuberculosis</I>, and ecumicin may serve as a lead compound for anti-TB drug development.</P>

<P>UV radiation is the primary cause of skin photoaging, which results in an increase in matrix metalloproteinases and degradation of collagen. Developing new natural antioxidant as photoprotective agents has become a popular area of research. Orobanche cernua Loefling is a parasitic plant that is rich in phenylethanoid glycosides (PhGs). This study investigated the photoprotective effects of the ethanolic extract of Orobanche cernua Loefling (OC) and its principal component acteoside on UVB-induced photoaging as well as their underlying molecular mechanisms in normal human dermal fibroblasts (NHDFs). Biological testing demonstrated that OC and acteoside possessed significant photoprotective activities, reducing MMP and IL-6 levels while improving type-I procollagen synthesis in UVB-irradiated NHDFs. Further study showed that the protective mechanisms were the improvement of transcription factor Nrf2-mediated antioxidant defensive system, suppression of MAPK/AP-1 and activation of the TGF-/Smad pathway. Together, our results suggested that OC might be a promising antiphotoaging agent against UV radiation-induced skin damage.</P>

Gao, Jing,Xie, Li,Yang, Wan-Shui,Zhang, Wei,Gao, Shan,Wang, Jing,Xiang, Yong-Bing Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.3
Hepatocellular carcinoma is a common disorder worldwide which ranks 5th and 7th most common cancer among men and women. In recent years, different incidence trends have been observed in various regions, but the reasons are not completely understood. However, due to the great public efforts in HCC prevention and alternation of lifestyle, the roles of some well documented risk factors played in hepatocarcinogenesis might have changed. This paper summarizes both the environmental and host related risk factors of hepatocellular carcinoma including well established risk factors such as hepatitis virus infection, aflatoxin and alcohol, as well as possible risk factors such as coffee drinking and other dietary agents.
TIGHT TOUGHNESS CONDITION FOR FRACTIONAL (g,f,n)-CRITICAL GRAPHS
Wei Gao,Li Liang,Tianwei Xu,Juxiang Zhou 대한수학회 2014 대한수학회지 Vol.51 No.1
A graph G is called a fractional (g,f,n)-critical graph if any n vertices are removed from G, then the resulting graph admits a fractional (g,f)-factor. In this paper, we determine the new toughness condition for fractional (g,f,n)-critical graphs. It is proved that G is fractional (g,f,n)-critical if t(G) ≥ b3-1+bn/a. This bound is sharp in some sense. Furthermore, the best toughness condition for fractional (a, b,n)-critical graphs is given.
Precision Nanometrology and its Applications to Precision Nanosystems
Wei Gao 한국정밀공학회 2005 International Journal of Precision Engineering and Vol.6 No.4
In this paper, a new field of metrology called "precision nanometrology" is presented. The "precision nanometrology" is the result of evolutions of the traditional "precision metrology" and the new "nanometrology". "Precision nanometrology" is defined here as the science of dimensional measurement and motion measurement with 100 ㎚ to 0.1 ㎚ resolution/uncertainty within a range of micrometer to meter. The definition is based on the fact that nanometrology in nanoengineering and the precision industries, such as semiconductor industry, precision machine tool industry, precision instrument industry, is not only concerned with the measurement resolution and/or uncertainty but also the range of measurement. It should also be pointed out that most of the measurement objects in nanoengineering have dimensions larger than I micrometer. After explaining the definition of precision nanometrology, the paper provides several examples showing the critical roles of precision nanometrologv in precision nanosystems, including nanometrology system, nanofabrication system, and nanomechatronics system.
