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.

Heterogeneous catalysts with low cost, environmentally friendly, highly effective and ready separation from aqueous solution are highly desirable. Magnetic CuO-Fe3O4 nanoparticles, a type of non-toxic bimetallic transition metal oxide, is a promising heterogeneous catalyst for activation of peroxymonosulfate (PMS) to generate reactive oxygen species (ROS) that has not been previously investigated. In this study, the activation of PMS by CuO-Fe3O4 nanoparticles was evaluated using the degradation of 4-chlorophenol as a model reaction. Several critical factors such as pH, catalyst dosage and PMS concentration were investigated. CuO-Fe3O4/PMS system demonstrated a wide effective pH range to degrade 4-chlorophenol, namely 5.5 to 9.5. With the increase of the catalyst dosage, the degradation efficiency of 4-chlorophenol appeared to increase first and then decrease, that the inflection point was 0.5 g/L. Elevated PMS concentration obviously improved the decomposition of 4-chlorophenol; however, the plateau was reached when the PMS concentration was 8mM. Further increase in PMS concentration would not significantly improve the removal efficiency. Through examining the effects of scavengers and electron spin resonance (ESR) analyses, CuO-Fe3O4 nanoparticles were proven to activate PMS through a non-radical and radical pathway to generate singlet oxygen, sulfate radicals and hydroxyl radicals. Based on results, CuO-Fe3O4 nanoparticles were effective, environmentally friendly and low cost catalysts for efficient activation of PMS. These features make CuO-Fe3O4 nanoparticles a readily available heterogeneous catalyst to activate PMS for refractory organic pollutants degradation in advanced oxidation processes (AOPs).

To develop a cheonggukjang with high content of menaquinone (MK), bacterial strains were isolated from good quality cheonggukjang, and MK productivities of isolated strains were determined by high-performance liquid chromatography. After sensory evaluation and MK determination, a potential probiotics, BY01, with acceptable sensory quality and high productivity of MK was isolated. Fermentation under aerobic condition produced more MK than that obtained under anaerobic condition, and the synthesized MK mainly remained in the form of endocellular deposit. To identify species of strain BY01, biochemical tests and gyrase B gene (gyrB) sequence analysis were carried out, and strain BY01 was identified as Bacillus amyloliquefaciens. The content of MK in cheonggukjang fermented with B. amyloliquefaciens BY01 reached 7.54 μg/g, 2-fold higher than that of commercial cheonggukjang products. This is the first report on the isolation of B. amyloliquefaciens as a superior MK producer in cheonggukjang fermentation.
Nonlinear Instability of Angle Section Beams under Uniformly Distributed Loads

This paper presents a study on the flattening behavior of angle-section beams of finite length subjected to uniformly distributed transverse loads. Analytical solutions for static instabilities of angle-section beams when they are bent about their weak axis are derived using energy methods. The basic assumptions used in the present study are that the total strain energy of an angle-section beam subjected to a uniformly distributed load can be simplified into a two-stage process. One is the bending response of the two legs behaving as the plate; the other is the bending response as a beam with flattened section. The nonlinear instability is derived by applying the minimum potential energy principle and the corresponding static critical moments associated with the section flattening-induced buckling are determined. To validate the analytical solution developed, nonlinear finite element analyses are also conducted. Good agreement between the present solution and the FEA results is demonstrated.

In this experiment, we selected "Tangshan bone china" 10.5-inch white porcelain flat plate produced by five differententerprises as experimental samples to study the erosion of bone porcelain enamel by different kinds of acidic reagents atdifferent temperatures. The specific experimental process was as follows: at different temperatures, 20% hydrochloric acid,30% sulfuric acid, 100 g/L citric acid and 10% acetic acid were used to continuously erode the sample glaze for 10h, and thewhiteness and 45º mirror direction gloss were measured every 2h. The results show that different acidic reagents at differenttemperatures have significant differences in the erosion characteristics and strength of bone porcelain glaze, and the corrosionresistance of products from different enterprises also have significant differences.

Precast concrete frame structure with nonrectangular columns are becoming attractive to researchers and engineers owing to advantages such as avoiding column protrusion from walls and saving space. This paper presents the experimental investigation of a full-scale precast concrete frame structure with L-shaped columns (PCFS) subjected to reverse cyclic loading. The precast connection adopted grouted anchor connection. As a comparison and benchmark, one full-scale monolithic sample (RCFS) was also tested. The results indicates that the greater steel ratio in the grouted anchor connection region leads to a high local stiffness of the elements, which contributed to delaying occurrence of the first crack at the grouting holes. The failure mode, lateral load capacity, stiffness degradation, load-carrying capacity degradation, energy-dissipating capacity, ductility and interlayer residual deformation were compared between two specimens. PCFS specimen exhibited comparatively better hysteretic behavior, energy-dissipating capacity, residual deformation-resisting capacity and ductility. For RCFS and PCFS specimens, the peak load difference was within 7%. About 15% increases in ductility were observed for PCFS specimen compared with RCFS specimen. The test results would provide reference for the application of the precast concrete structure with nonrectangular columns in the new residential buildings.
