Item Metadata only Modelling Supply Chain Measurement in Omni-Channel Supply Chain(2025-09-01) Liangrokapart J.; Prakongwittaya S.; Liangrokapart J.; Mahidol UniversityRetail business has transformed into omni-channel retail, a modern approach utilizing multiple channels several years ago. The performance measurement used in the past which mainly focused on financial measures may not be applicable to omni-channel... retail. This research aims to model a supply chain performance measurement framework for the omni-channel supply chain and to draw a relationship among performance measures and their association with the goals of resource efficiency, customer servicePublication Metadata only Precision analysis of posterior corneal topography measured by Visante Omni: Repeatability, reproducibility, and agreement with orbscan II(2012-02-01) Sabong Srivannaboon; Suksri Chotikavanich; Chareenun Chirapapaisan; Sirilux Kasemson; Wasin Po-ngam; Mahidol UniversityPURPOSE: To evaluate the repeatability and reproducibility of posterior corneal curvature and posterior corneal elevation best-fit sphere (BFS) obtained with the Visante Omni (Carl Zeiss Meditec) and to compare the results with the Orbscan II... (Bausch & Lomb). METHODS: Thirty eyes from 30 healthy volunteers were included in this study. All patients were examined 5 times with the Visante Omni and Orbscan II by 2 independent operators.

Methods Heart rate (HR, b/min), oxygen consumption (VO2..., L/min), minute ventilation (VE, L/min), respiratory rate (RR, b/min) and ratings of perceived exertion (OMNI cycle Scale; RPE) for the overall body (RPE-O), legs (RPE-L), and chest (RPE-C) were determined at the end of each of 3-min exercise stagesPublication Metadata only The design of omnidirectional terahertz mirror and TM mode filter based on one-dimensional photonic crystal: Potential for THz communication system(2015-01-01) A. Aming; R. Chitaree; Mahidol University© 2015 SPIE. Numerical results using transfer matrix method (TMM) of omnidirectional photonic band gap (omni-PBG) for both TE and TM polarizations from 0 to 89 for THz responses are presented. Such omni-PBG design is based on one-dimensional... shift for the omni-PBG. High reflectivity omni-PBG within a certain wavelength is found in the range of 390-515 μm. This suggests a practical way of controlling the thickness of layer to achieve a suitable omni-PBG. This structural design showsPublication Metadata only Comparison of the Performance of Point-of-Care and Device Analyzers to Hospital Laboratory Instruments(2003-01-01) Wanvisa Boonlert; Porntip H. Lolekha; Gerald J. Kost; Somsak Lolekha; Mahidol University; University of California, DavisPoint-of-care testing plays an important role in critical care medicine. This study evaluated the performance of the OPTI CCA and OMNI 9 critical care analyzers by comparing them to our currently used routine instruments (Stat Profile Ultra C, CRT... obtained with the OPTI and OMNI were within acceptable limits, and the recovery of analytes was close to 100%. Most comparison results from the OPTI and OMNI correlated well with results from currently used routine instruments.

Objective: Duodenal ulcer perforation after laparoscopic Roux-ex-Y gastric bypass (LRYGB) for morbidly obese patient is uncommon. However, the morbidity and mortality rate will be increased if the diagnosis is delayed. We reported clinical presentations, surgical approach as well as outcome of first perforated duodenal ulcer after LRYGB in E-Da hospital. Case presentation: A 34 years old morbidly obese female who underwent successful LRYGB in 2006. Five years later, she developed severe epigastric pain and marked tenderness at this area. No pneumoperitoneum was demonstrated on abdominal CT scan. First diagnostic laparoscopy was done and showed unexplained hemoperitoneum at subhepatic area without definite cause of abdominal pain. Unfortunately, she had to undergo re-diagnostic laparoscopy on postoperative day 2 because bile content was present in abdominal drain. Luckily, the perforated duodenal ulcer was detected at 1st part of duodenum and closed properly by simple suture techniques. Postoperatively, there was no complication and she was discharged home uneventfully. Helicobacter pylori and life-long proton pump inhibitor were prescribed. Upon 3-month follow-up, she had no abdominal pain or other complications. Conclusion: The diagnosis of perforated duodenal ulcer after LRYGB for morbidly obese patients is challenging. Although laparoscopic simple suture is safe and feasible in acute perforated scenario, this might carry high recurrent rate due to the remaining parietal cells in gastric remnant. Nevertheless, the role and timing of definitive acidreducing surgery need to be addressed by having well-designed studies in future.Publication Metadata only Study of semi deterministic model for fifth-generation (5G) wireless networks(2019-01-01) Supachai Phaiboon; Pisit Phokharatkul; Kasem Bundit University; Mahidol University) and standard deviation of the zero-mean Gaussian random both line-of-sight (LOS) and non line-of-sight (NLOS) are compared at the frequencies of 28, 38 and 73 GHz.
