Evaluating Green Supply Chain Management with Incomplete Information
Ming-Lang Tseng,Ru-Jen Lin,Anthony Shun Fung Chiu 대한산업공학회 2012 Industrial Engineeering & Management Systems Vol.11 No.2
There has been a growing interest in firms’ environmental sustainability activities to improve environmental practices in their supply chain. This study aims to deal with supplier evaluation of firm’s green supply chain management (GSCM) criteria with incomplete information. Nevertheless, the suitable supplier is a key strategic direction in eliminating environmental impact on supply chain management for manufacturing firms. The firm’s GSCM criteria and supplier selection need to be unified as a system to improve the firm’s performance.
Fuzzy AHP Approach to TQM Strategy Evaluation
Ming-Lang Tseng,Yuan-Hsu Lin,Anthony SF Chiu,Chia Yi Chen 대한산업공학회 2008 Industrial Engineeering & Management Systems Vol.7 No.1
In recent years, many electronics producing firms have looked upon total quality management (TQM) strategy as a means by which they could maintain competitive advantage. This empirical research evaluates TQM strategic factors in order to determine the critical success factors in environmental uncertainty. Fuzzy analytic hierarchy process (FAHP) is the proposed research methodology to discuss and tackle the different decision criteria like effective leadership, people management, customer focus, strategic plan and process management, being involved in identifying the TQM strategic critical success factors with uncertainty. The result shows that effective leadership is the most critical success factor in TQM strategy.

Aims: TASL HCV Registry (TACR) is a nationwide registry program organized and supervised by Taiwan Association for the Study of the Liver (TASL), which aims to setup the database and biobank of patients with chronic hepatitis C (CHC) in Taiwan. The present study aimed to evaluate the treatment outcome of sofosbuvir (SOF)/ledipasvir (LDV) in Taiwanese CHC patients in TACR. Methods: By May 2020, 19 tertiary hospitals, 23 community hospitals and one primary care clinic join the TACR program. The baseline characteristics, prior liver and non-liver related medical history, DAA regimens, laboratory results, treatment course and outcome were recorded. The primary objective was sustained virological response, defined as undetectable HCV RNA 3 months after end-of-treatment (SVR12). Results: A total of 4742 SOF/LDV+ ribavirin treated CHC patients with available SVR12 data from 39 sites were enrolled in the current analysis. The mean age was 61.3 years, and female accounted for 54.8% of the population. The dominant viral genotypes were GT1b (52.6%) and GT2 (35.6%). 1354 (28.6%) patients had liver cirrhosis, including 156 (3.3%) with liver decompensation, 552 (11.6%) had preexisting hepatocellular carcinoma (HCC) before DAAs treatment and 413 (8.7%) had hepatitis B virus dual infections. The overall SVR12 rate was 98.5%, with 98.5%, 98.2%, 99.7% and 98.6% in treatment- naïve non-cirrhotics, treatment-naïve cirrhotics, treatment- experienced non-cirrhotics and treatment-experienced cirrhotics patients, respectively. While patients were stratified by HCV genotype, the SVR12 was 98.5%, 98.4% and 98.5% among those with GT1, GT2 and GT6 infection, respectively. The strongest factor independent associated with treatment failure was DAA adherence < 60% (odds ratio [OR]/95% confidence intervals [CI]: 125.4/25.7-612.4, P<0.0001), followed by active HCC (OR/CI: 6.20/2.57-14.97, P<0.0001), HIV co-infection (OR/CI: 3.01/1.14-7.92, P=0.026), and male gender (OR/ CI: 1.85/1.09-3.13, P=0.023). The eGFR decreased significantly at the end of treatment (EOT) (89.3 ml/min/1.73㎡ vs. 93.2 ml/min/1.73㎡, P< 0.001) and remained stable 3 months after EOT (89.3 ml/min/1.73㎡). However, the decreased eGFR was observed only in patients whose baseline eGFR > 90 ml/ min/1.73㎡. Instead, patients with chronic kidney diseases whose pretreatment eGFR < 60 ml/min/1.73㎡ had improved eGFR after SOF/LDV. Conclusions: SOF/LDV is highly effective in treating CHC patients in real-world setting of Taiwan. The satisfactory result could be explicitly generalized to patients with different viral genotypes and liver disease severities.

A 12-week-old baby with a vein of Galen aneurysmal malformation (VGAM) was successfully treated with performing transarterial microcatheter-directed embolization with Berenstein Liquid Coils and n-butyl cyanoacrylate in the feeding arteries. Post-procedure angiography showed a marked decrease of the blood flow into the dilated vein of Galen. Three months later, follow-up angiography showed that the vein of Galen aneurysmal malformation had totally disappeared, and the baby recovered very well without any sequelae. We report here on this interesting case along with a review of the relevant literature, and we aim to enhance physicians' awareness of the treatment for VGAMs.

This pictorial review provides the principles of extracorporeal membrane oxygenation (ECMO) support and associated CT imaging features with emphasis on the hemodynamic changes and possible imaging pitfalls encountered. It is important that radiologists in ECMO centers apply well-designed imaging protocols and familiarize themselves with post-contrast CT imaging findings in patients on ECMO.
Investigating the effects of a range shifter on skin dose in proton therapy

Proton treatment may deliver a larger dose to a patient’s skin than traditional photon therapy, especially when a range shifter (RS) is inserted in the beam path. This study investigated the effects of an RS on skin dose while considering RS with different thicknesses, airgaps and materials. First, the physical model of the scanning nozzle with RS was established in the TOol for PArticle Simulation (TOPAS) code, and the effects of the RS on the skin dose were studied. Second, the variations in the skin dose and isocenter beam size were examined by reducing the air gap. Finally, the effects of different RS materials, such as polymethylmethacrylate (PMMA), Lexan, polyethylene and polystyrene, on the skin dose were analysed. The results demonstrated that the current RS design had a negligible effect on the skin dose, whereas the RS significantly impacted the isocenter beam size. The skin dose was increased considerably when the RS was placed close to the phantom. Moreover, the magnitude of the increase was related to the thickness of the inserted RS. Meanwhile, the results also revealed that the secondary proton primarily contributed to the increased skin dose.
