This study comprehensively investigates three types of graphite materials as potential anodes for potassium-ion batteries. Natural graphite, artificial carbon-coated graphite, and mesocarbon microbeads (MCMB) are examined for their structural characteristics and electrochemical performances. Structural analyses, including HRTEM, XRD, Raman spectroscopy, and laser particle size measurements, reveal distinct features in each graphite type. XRD spectra confirm that all graphites are composed of pure carbon, with high crystallinity and varying crystal sizes. Raman spectroscopy indicates differences in disorder levels, with artificial carbon-coated graphite exhibiting the highest disorder, attributed to its outer carbon coating. Ex-situ Raman and HRTEM techniques on the electrodes reveal their distinct electrochemical behaviors. MCMB stands out with superior stability and capacity retention during prolonged cycling, attributed to its unique spherical particle structure facilitating potassium-ion diffusion. The study suggests that MCMB holds promise for potassium-ion full batteries. In addition, artificial carbon-coated graphite, despite challenges in hindering potassium-ion diffusion, may find applications in commercial potassium-ion battery anodes with suitable coatings. The research contributes valuable insights into potassiumion battery anode materials, offering a significant extension to the current understanding of graphite-based electrode performance.

Purpose - Urban agglomeration construction is one of national strategic plans to accelerate the development of industrialization and urbanization in China, which has threatened the eco-environmental quality at the same time. This paper selected the urban agglomeration in the middle reaches of the Yangtze River as the research area. Research design, data, and methodology - The the slack-based measurement (SBM) model considering undesirable outputs is applied to measure the eco-efficiency of this urban agglomerations during 2006-2015. Results - The empirical results show that average eco-efficiency of the urban agglomeration in the middle reaches of the Yangtze River is 0.595. Regional ecological development is unbalanced. The highest eco-efficiency is recorded at Wuhan Metropolitan Area, and the lowest one is at the Changsha-Zhuzhou-Xiangtan City Group. Energy consumption and waste dust emissions are the key factors led to ecological inefficiency. Based on this, potentials for energy saving and waste dust reducing are calculated. Conclusions - Finally, this study provides policy implications targeted to promote the coordinating development of economy and eco-environment under the construction of urban agglomeration.

일본 애니메이션 영화는 독특한 매력이 가지고 있어 세계의 광범위한 찬양을 받았다. 그리하여 역사적, 문화적 요인의 영향을 미치기 때문에 영화 속에 어느 정도 비극적 분 위기 나타낸다. 따라서 비극적 색채도 일본 애니메이션 영화의 특색중의 하나이다. 일본 애니메이션 영화의 종류가 다양하지만 그 중에서는 제일 매력적인 것은 상업 애니메이션 영화중의 극장 애니메이션영화이라고 할 수 있다. 일본 극장 애니메이션 영화는 제작하기가 아주 복잡하고 표현형식이 훌륭하다. 그리 고 제작품은 일본 애니메이션의 수준을 대표할 수 있으며 사회적 영향이 크고 깊은 연구 가치를 가진다. 오늘날에 일본 애니메이션은 많은 연구 성과를 거두었지만 그 중에서는 비극의식 탐구에 관한 연구는 아직 많지 않다. 일본은 비극의식을 강한 민족이다. 그러니까 일본 애니메이션의 비극의식에 관한 연 구를 중요한 의미를 지니고 있다. 일부 연구원들이 일본 비극의식을 연구할 때 “죽음” 에 한하여 탐구한다. 본문은 일본의 인문 사회과학 등 다방면을 통해서 분석해 보고자 한다.

Enhancing yield has been a major challenge of agriculture. In rice, tiller number is one of the important biomass and yield components. A maize mutant grassy tillers1 (gt1) increases lateral branches in maize. The GT1 gene encodes a class I homeodomain leucine zipper (HD-Zip) protein. In maize, the gt1 expression is induced by shading and is dependent on the activity of teosinte branched1 (tb1), a major domestication locus controlling tillering and lateral branching. To estimate the biological role and agricultural utility of gt1 in rice, rice homologue (OsGT1) has been isolated and its overexpressors and RNAi lines were generated. Field data showed that OsGT1 overexpressors reduced tillers and panicles while RNAi lines increased them, compared to wild type. Shade signal is an important factor in determining lateral branching. To understand the relationship between OsGT1 and shade avoidance, plants have been grown under 50% shading in the field. Also, double genetic combinations with phytochrome mutants (phyA, B, and C) are being examining for tillering phenotype. These ongoing researches will provide insights in determining the action of OsGT1 on branching and shade avoidance in rice.
