The relationship between three phenological parameters and somatic embryogenesis was investigated during a two-year period. Staminodes and petals from six hybrids and two clones as controls were sowed on three distinct primary callus growth media. Flowering level, fructification level, and leaf thrusts rhythm as phenological parameters were measured simultaneously during the weekly harvest of flower buds. Mean and coefficient of variation of the measured parameters highlighted stable phenological phases. The relationship between phenological parameters and somatic embryogenesis was investigated first by comparing the variation of somatic embryogenesis and that of the phenological parameters, and second by using Pearson's linear correlation. Except for the fructification level in both control clones the first year, the other parameters recorded stable phenological phases, regardless of the genotype and year. Favorable and unfavorable phases for the somatic embryogenesis were identified. In hybrids, favorable phases included February, August, September, and October. In both control clones, time interval propitious to embryogenesis stretched from February to December. The significance of the coefficient of correlation seemed to establish a relationship between somatic embryogenesis and phenology. However, a causal link could not be established. Leaf thrusts rhythm was revealed to be the phenological parameter most linked to somatic embryogenesis. Attempts to optimize embryogenesis during unfavorable phases, showed that a correction of 2.4 D/TDZ concentration is not the solution.

Electrochemical Oxidation of Amoxicillin in Its Commercial Formulation on Thermally Prepared RuO₂/Ti

In this work, a ruthenium dioxide electrode has been prepared by thermal decomposition at 400 ℃ then used for the oxidation of commercial amoxicillin. The physical characterization showed that RuO₂ electrode presents a mud cracked structure. Its electrochemical characterization has revealed an increase of the voltammetric charge in acid electrolyte compared to neutral electrolyte indicating the importance of protons in its surface redox processes. The voltammetric study of the oxidation of amoxicillin has been investigated. It has been obtained that the oxidation of amoxicillin is controlled by both adsorption and diffusion processes. Moreover, the oxidation of amoxicillin occurs via direct and indirect processes in free or electrolyte containing chlorides. Through preparative electrolysis, enhancement of amoxicillin oxidation was observed in the presence of chloride where the amoxicillin degradation yield reached more than 50 % compared to less than 5% in the absence of chlorides. Spectrophotometric investigations have revealed the degradation of intermediates absorbing at 350 nm.

Automated genome-wide visual profiling of cellular proteins involved in HIV infection.

Genovesio, Auguste,Kwon, Yong-Jun,Windisch, Marc P,Kim, Nam Youl,Choi, Seo Yeon,Kim, Hi Chul,Jung, Sungyong,Mammano, Fabrizio,Perrin, Virginie,Boese, Annette S,Casartelli, Nicoletta,Schwartz, Olivier Mary Ann Liebert, Inc 2011 Journal of biomolecular screening Vol.16 No.9

<P>Recent genome-wide RNAi screens have identified >842 human genes that affect the human immunodeficiency virus (HIV) cycle. The list of genes implicated in infection differs between screens, and there is minimal overlap. A reason for this variance is the interdependence of HIV infection and host cell function, producing a multitude of indirect or pleiotropic cellular effects affecting the viral infection during RNAi screening. To overcome this, the authors devised a 15-dimensional phenotypic profile to define the viral infection block induced by CD4 silencing in HeLa cells. They demonstrate that this phenotypic profile excludes nonspecific, RNAi-based side effects and viral replication defects mediated by silencing of housekeeping genes. To achieve statistical robustness, the authors used automatically annotated RNAi arrays for seven independent genome-wide RNAi screens. This identified 56 host genes, which reliably reproduced CD4-like phenotypes upon HIV infection. The factors include 11 known HIV interactors and 45 factors previously not associated with HIV infection. As proof of concept, the authors confirmed that silencing of PAK1, Ku70, and RNAseH2A impaired HIV replication in Jurkat cells. In summary, multidimensional, visual profiling can identify genes required for HIV infection.</P>

승용차의 내부소음평가에 대한 연구사고찰

Schick, August 한국감성과학회 1998 감성과학 Vol.1 No.2

이 글은 영구의 자동차내부 소음연구와 보버르트(Bobbert)의 첫 번재 독일어로 쓰인 연구를 다루고 있다. 승용차내부소음은 높은 적외파음향(infra sound)으로 특징지어 진다. 그런 까닭으로 그러한 종류의 소음을 A-평가계측(A-rated measurement)으로 그 영향을 파알하는 것은 한계가 있다. 자동차음향공학은 특히 인공청각(artificial head)기술의 발전, 소리의 합성적 제조 및 다양한 자동차 내부 음색(timbre)에 대한 일본연구가들 (하쉬모토, 쿠와노, 남바)에 의해 상당산 성취를 경험하였다. 위의 연구들은 무엇보다도 의미분별기법(Semantic Differentials)과 다차원측정방법(Multidimen-sional Scaling)을 사용하고 있다. 그러한 기법의 사용은 심리측정방법을 심리음향학(Psycho-acoustics), 특히 츠뷔커학파(Zwicker school)의 심리음향학 방법론과 결합한 것으로 볼 수 있다.

Bible Translation and Globalization —a Cognitive Perspective

Ernst-August Gutt 한국번역학회 2009 번역학연구 Vol.10 No.4

As the range of information on offer in the global information market keeps growing, the Bible, as one of the most widely translated books, faces increasing competition. Applying cognitive insights into the inferential nature of communication, this paper highlights the significance of the cognitive communicability condition for successful communication. This condition is particularly important in Bible translation because the incongruity in cognitive environments between receptors and original readership is often very high. Another problem is the term ‘translation’ in that the expectations it raises tend not to be standardized and that they lack in realism with respect to the cognitive workings of communication. The paper makes suggestions for how both these problem areas might be addressed. It ends by pointing out how a clearer recognition of the cognitive communicability condition can be of value more generally in globalization.
