Environmental Management in Industry

환경문제를 야기시키는 원인은 인간 그 자체에 있으며, 경제주체별로는 개인, 기업, 정부로 볼 수 있다. 시시각각 변화하고 강화되여가는 국제환경질서에 대처하기 위해서는 기업과 정부가 협조적인 관계를 유지하면서 각각의 역할을 하여야하는 바, 기업은 사회공헌책임주의에 입각하여 환경친화책인 기업경영을 도입, 실천해야 하며, 정부는 이를 지원, 촉진하기 위한 정책을 펼쳐야 할 것이다. 이 논문은 지구차원에서의 환경문제, 미국과 한국의 최근 환경정책 그리고 기업에서의 환경경영도입의 중요성과 환경경영이 모든 조직기능에서 통합 고려되어야 하는 필요성올 논의하였으며, 기업의 환경경영을 위한 환경성과지표, 환경심사, 전과정분석 등의 요소들을 검토하였다. 끝으로 3M, Body Shop, Baxter International 둥 3개 기업에 있어서의 환경경영의 사례를 동해 환경경영에 의한 기업이익을 엿볼 수 있었다.

Background Melittin, a major component of honeybee venom, is known to possess anti-allergic, anti-inflammatory, anti-arthritis, and anti-cancer. Despite its great promise as an agent for various diseases, the therapeutic applications of melittin have been severely limited by its nonspecific cytotoxicity and hemolytic activity. Objective We synthesized a hybrid peptide (melittin-dKLA), composed of melittin and the pro-apoptotic peptide (dKLA), and evaluated its potential toxicity in ICR mice following a single or repeated subcutaneous dose administration. Results Mice administered a single subcutaneous dose of melittin-dKLA showed no mortality or abnormal clinical signs in all animals. Similarly, mice administered a repeated subcutaneous dose of melittin-dKLA resulted in no deaths. Crust formation and induration were observed in the male and female mice in the 5 and 20 mg/kg, respectively. The hematological parameters and serum biochemical analysis did not show any changes by melittin-dKLA. In repeated subcutaneous dose study, the mice in the 20 mg/kg group showed a significant increase in the relative weight of the spleen compared to the control group. Although the difference was not statistically significant. Mice exhibited a common pattern of change. Conclusion Taken together, our results suggest that the toxicity of melittin-dKLA is higher than 20 mg/kg both as a single and a repeated subcutaneous administration in ICR mice. Thus, it is suggested that it will be an important data in the development of new drug for melittin-dKLA.

To isolate the useful and interesting plant genes in large quantities from Brassica raga, random partial sequencing of leaf and inflorescence cDNA clones of Brassica rapa was carried out. cDNA libraries were made with mRNA prepared from leat and inflorescence organ of Brassica rapa, respectively. Approximately 50% of the cDNA clones contained cDNA insert longer than 300bp. Most of the clones have the poly(A) tail sequences. Partial nucleotide sequences of individual cDNA clone from both organs have been determined and compared with nucleotide: sequences in EMBL and amino acid sequences in PIR data bank. Preliminary results promise a good chance to get useful genes by this attempt.
Correlation of oxygen vacancies to various properties of amorphous zinc tin oxide films
Sung, Nark-Eon,Lee, Han-Koo,Chae, Keun Hwa,Singh, Jitendra Pal,Lee, Ik-Jae American Institute of Physics 2017 Journal of Applied Physics Vol.122 No.8
<P>Amorphous ZnO-SnO2 (a-ZTO) films were deposited on quartz substrates at working pressures of 5 <= P-W <= 12 mTorr using radio frequency sputtering. PW affected the occurrence of oxygen deficiencies in the films. X-ray photoemission spectroscopy, near edge X-ray absorption fine structure (NEXAFS), and ultraviolet photoelectron spectroscopy-based spectroscopy analyses showed that oxygen vacancies (OVs) influence the evolution of the optical and electrical properties of a-ZTO films. NEXAFS reflects the onset of OVs. Low P-W contributes to the evolution of a chemical structure with numerous OVs. This result can be applied to improve the electro-optical properties of a-ZTO films. As P-W decreased, the carrier concentration increased, carrier mobility increased, and film resistivity decreased. Average optical transmittance in the visible region was >90%, and increased as P-W decreased. Published by AIP Publishing.</P>
