In this paper we calculate three geometric constants, namely the von Neumann-Jordan constant, the James constant, and the Dunkl-Williams constant, for Morrey spaces and discrete Morrey spaces. These constants measure uniformly nonsquareness of the associated spaces. We obtain that the three constants are the same as those for $L^1$ and $L^{\infty}$ spaces.

Complex viscosities of dense alumina slurries over 45% volume density measured with the oscillating method were correlated well with Casson model. Among several monosaccharides and disaccharides studied here, fructose and sucrose showed good rheological properties in making dense alumina slurry plastic compared to other monosaccharides and disaccharides like glucose, galactose, arabinose, xylose and maltose. Sucrose content or additional water content in dense alumina slurry with sucrose contributed to the plasticity of the slurries.

In this paper, we prove the discrete Hardy inequality through the continuous case for decreasing functions using elementary properties of calculus. Also, we prove the Carleman's inequality through limiting the discrete Hardy inequality with applications of Taylor series.

We present some proofs of the classical integral Hardy inequality. Our approach makes use of continuous functions with compact support in (0, ${\infty}$), homogeneity of the norm and Schur's criterion for integral operators.

Bio-oil instability, or aging, is a significant problem for the long-term storage of fast pyrolysis oils. We investigated bio-oil aging at the molecular level using Fourier-transform ion cyclotron resonance mass spectrometry. Petroleomic analysis suggests that bio-oil aging is resulted from the oligomerization of phenolic lignin products whereas 'sugaric' cellulose/hemicellulose products have negligible effect.

ESCO 관리자교육(국제세미나)에서 CCI(Clinton Climate Initivative)의 아시아 지역 매니저 크리스토퍼 실리의 발표가 있었다. 그는 CCI에서 세계 40개 도시를 무대로 진행하고 있는 빌딩 개조 프로그램에 대해서 설명했다. 이 프로그램은 ESCO에서 중요시되는 합리성과 효율성이라는 두 가지 키워드와 맞물리면서 점점 시장을 확장시켰다. 특히 아직 ESCO 사업에 대한 인식이 부족한 아시아 국가에서 사업을 진행하는 것은 불모지에서 가능성을 발견하는 과정이었을 것이다. 낙후된 빌딩에서 발생할 수 있는 에너지 손실과 이산화탄소 배출을 분석하고 이를 토대로 최적의 공정을 제시하고 있는 CCI의 사업을 크리스토퍼 실리의 발표 자료를 바탕으로 소개한다.
