＜正＞This paper illustrates how Taiwan Semiconductor Manufacturing Company （TSMC） implements business process reengineering （BPR） techniques to enhance operation efficiency. Since the approach is not a new concept and a lot have been written about it, this paper focuses on the experience sharing and lessons learned. To remain world’s best dedicated IC foundry company and to face the global competitors, all the functional areas of the company need to be properly integrated, with each understanding the importance of cross functional processes. The paper concludes that even BPR has been introduced for more than a decade, organizations can still benefit from it. Real cases, including a Nation Quality Award winning case, are given to show the processes and results.

随着2005年2月16日《京都议定书》的正式生效,温室气体排放问题引起了电力工业界的广泛重视。《京都议定书》等新出台的温室气体排放政策本质上体现了配额-交易的排放控制策略,这种策略曾在美国被用来控制氮氧化合物(NOX)以及二氧化硫(SO2)等污染气体的排放。配额-交易排放策略下,温室气体排放不再受到刚性的排放上限约束,取而代之的是一定数量的可交易的排放配额限制。针对这一变化,本文提出了一种在配额-交易排放控制策略下经济调度中考虑温室气体排放的新方法。该方法通过引入排放影响因子将排放产生成本与其他发电成本 (例如燃料成本)一并计入到扩展的发电成本中,在寻求扩展发电成本最小的同时,自动确定系统排放配额的使用量,从而,在整体上确保了系统发电的经济性。文章采用Sorted table based lambda-iteration方法对所提出模型进行了求解,该方法可以同时处理发电成本曲线连续与分段连续的机组。算例分析通过对一个10机系统的测试,表明了本文方法的有效性。另外,文中还对系统运行的经济性与排放之间的折中关系进行了分析。

Extended-spectrum β-lactamases (ESBLs) and/or AmpC enzymes combined with deficiency of porins OmpK35 and OmpK36 are important for the development of carbapenem-resistant Klebsiella pneumoniae. We characterized the clinical K. pneumoniae human isolates and investigated the effect of meropenem induction on the ompK35 and ompK36 mutation to develop carbapenem resistance from six carbapenem-susceptible ESBL-producing K. pneumoniae strains. 163 clinical K. pneumoniae isolates were grouped mostly into the ESBL + AmpC (44.2%) and ESBL (42.9%) phenotypes. The resistance rate differed between cephalosporins (52.1% for cefepime - 97.5% for cefotaxime) and carbapenems (16% for meropenem - 28.2% for imipenem) (P blaTEM, blaSHV, blaCTX-M-3-like, and blaCTX-M-14-like of AmpA β-lactamase genes and blaDHA and blaCMY of AmpC β-lactamase genes. Compared to all 163 clinical isolates, the 56 carbapenem-resistant isolates carried less frequently of blaTEM, blaCTXM-14-like, and blaCTXM-3-like and more frequently of blaDHA-1 and blaCMY-2. The carbapenem-resistant isolates differed in prevalence against imipenem, ertapenem, and meropenem and lacked OmpK35 more frequently than OmpK36, but abnormal PCR amplicons were detected fewer in the Omp K35-deficient group than in the OmpK36-deficient group (32.5% vs. 68.4%, respectively). The carbapenem-resistant isolate mostly carried blaDHA (91.1%) and three isolates carried blakpC-2. Following induction with meropenem insertion sequences in ompK36, not ompK36, were identified as IS5 for kp08, IS1 for kp15, and IS903 for kp16 isolates. OmpK36 deficiency increased resistance to ertapenem, but not imipenem and meropenem. Clinical isolates belonged mainly to ESBL + AmpC group and ESBL group with difference in resistance to cephalosporins and carbapenems, the bla genes. Carbapenem resistant isolates lacked OmpK35 expression, than the OmpK36 expression, Meropenem induction developed the carbapenem resistant isolates with insertion of different insertion
