Fuzzy entropy measures are valuable tools in decision-making when dealing with uncertain or imprecise *** exist many entropy measures for Pythagorean Fuzzy Sets(PFS)in the literature that fail to deal with the problem of providing reasonable or consistent results to the *** deal with the shortcomings of the existing measures,this paper proposes a robust fuzzy entropy measure for PFS to facilitate decision-making under *** usefulness of the measure is illustrated through an illustration of decision-making in a supplier selection problem and compared with existing fuzzy entropy *** Technique for Order Performance by Similarity to Ideal Solution(TOPSIS)approach is also explored to solve the decision-making *** results demonstrate that the proposed measure can effectively capture the degree of uncertainty in the decision-making process,leading to more accurate decision outcomes by providing a reliable and robust ranking of alternatives.

Introduction: Musculoskeletal disorders (MSds) are a set of peri-articular conditions that result mainly in pain and functional discomfort. They represent a major occupational health problem in all areas of activity. The objective of this work was to determine the prevalence of MSds among street vendors in the city of Bangui in the Central African Republic (CAR). Meth.d.: A cross-sectional study was conducted from September 01 to October 31, 2021 in Bangui, the capital of CAR. The study population consisted of street vendors which were included at the entrance of 4 large markets of Bangui after giving informed consent. The sample size, calculated according to the Schwartz formula, was 384. Sociodemographic data (age, gender, level of education, marital status), professional data (the duration of sale in hours, the distance traveled per day);and health.d.ta (the health problems suffered by itinerant sellers and the means of dealing with them) were collected using a pre-establish.d.self-questionnaire. This collected data was processed using Microsoft Excel 2013 and Epi-Info version 7 software. Results: Among 384 street vendors included, women represented a quarter (24.9%). The average age was 27 years;the 25-34 age group was the most represented (50%). About two-thirds (64.8%) sold for at least 12 hours and traveled more than 10 km (69.3%) per day. The main health problems reported by street vendors were musculoskeletal disorders (95.8%). Their locations concerned the upper limbs shoulder 65.36% (251), elbow 24.22% (93). Non-ergonomic postures that stress the back and joints all day long, causing pain are risk factors for MSds. These MSds were treated by self-medication with non-steroidal anti-inflammatory drugs (22.0%), mainly sold on the street. Conclusion: MSds dominated the health problems of street vendors. These problems raise the need for recognition and support for these workers to optimize their performance while preserving their health through awareness and

作者： Solomon R. donnenfeld E.d. Perry h.d. 宋虎平 Ophthal. Consultants of Long Island Ryan Medical Arts Building 2000 North Village Avenue Rockville Centre NY 11570 United States

Purpose: To investigate the aqueous penetration of 3 commercially available ophthalmic fluoroquinolones. design:Prospective, double- masked, clinical study. Participants: Fiftytwo eyes of 52 patients. Intervention: Fifty- two patients undergoing cataract surgery were given preoperative topical gatifloxacin 0.3% (Zymar), moxifloxacin 0.5% (Vigamox), or ciprofloxacin 0.3% (Ciloxan). The patients were instructed to use their antibiotic drops 4 times a day for 3 days before surgery. On the day of surgery, patients were given their assigned antibiotic every 15 minutes for 3 doses, 1 hour before their procedure. At the time of surgery, 0.1 ml of aqueous fluid was aspirated from the anterior chamber with an air cannula needle attach.d.to a tuberculin syringe. The aspirate was immediately stored at- 70° C. Main Outcome Measure: Fluoroquinolone concentrations were determined by reverse- phase high- pressure liquid chromatography assay technique with ultraviolet detection at a wavelength of 275 nm. Results: Mean aqueous concentration of gatifloxacin in 16 eyes was 0.63 μ g/ml (standard deviation [Sd], 0.30),moxifloxacin in 14 eyeswas 1.31 μ g/ml (Sd, 0.46), and the mean concentration of ciprofloxacin in 22 eyes was 0.15 μ g/ml (Sd, 0.11). Conclusions: Bothmoxifloxacin (Pd gatifloxacin (Pd the aqueous humor at significantly higher levels than ciprofloxacin. Moxifloxacin penetrated into the aqueous humor at significantly higher levels than gatifloxacin (Phe anterior chamber levels of moxifloxacin and gatifloxacin may be due to the difference in antibiotic concentration.

在过去几年内,对中磁场磁选机用于分选风化的假象赤铁矿石和其它中等磁性矿石以及从原生和次生工业矿物中除去中等磁性杂质的需求日益增多。有关新型永磁材料的研究,如钐-钴(SmCo)和钕-铁-硼(NdFeB)也取得了巨大的进展,并且研究了磁场最佳布置,以及磁场强度、磁场梯度和工作间隙。在这方面,克洛克纳-洪堡-道依茨韦达格股份公司(Khd humboldt Wedag AG)研究出用于PERMOS^((R))圆筒磁选机的NdFeB永磁铁的新磁场布置形式,目前已在工业上应用。PERMOS^((R))磁选机内的磁系不再由在径向交替磁化的较大磁块构成,现在由许多小磁棒组成,这些小磁棒的磁化方向逐渐交替变化。本文介绍这一研究成果的重要特征及由此而得的用于干式和湿式分选的PERMOS^((R))OGMS型磁选机的设计特点。
