AbstractThe purpose of this study was to assess the diagnostic value of multifrequency MR elastography for grading necro-inflammation in the liver. Fifty participants with chronic hepatitis B or C were recruited for this institutional review board-approved study. Their liver was examined with multifrequency MR elastography. The storage, shear and loss moduli, and the damping ratio were measured at 56 Hz. The multifrequency wave dispersion coefficient of the shear modulus was calculated. The measurements were compared to reference markers of necro-inflammation and fibrosis with Spearman correlations and multiple regression analysis. Diagnostic accuracy was assessed. At multiple regression analysis, necro-inflammation was the only determinant of the multifrequency dispersion coefficient, whereas fibrosis was the only determinant of the storage, loss and shear moduli. The multifrequency dispersion coefficient had the largest AUC for necro-inflammatory activity A ≥ 2 [0.84 (0.71–0.93) vs. storage modulus AUC: 0.65 (0.50–0.79), p = 0.03], whereas the storage modulus had the largest AUC for fibrosis F ≥ 2 [AUC (95% confidence intervals) 0.91 (0.79–0.98)] and cirrhosis F4 [0.97 (0.88–1.00)]. The measurement of the multifrequency dispersion coefficient at three-dimensional MR elastography has the potential to grade liver necro-inflammation in patients with chronic vial hepatitis.

Purpose – The purpose of this paper is to quantitatively evaluate the effect of adhesive interlining on the appearance of tailored jackets with different rigidity. Design/methodology/approach – Four tailored jackets having the same pattern and fabric and three different adhesive interlinings or no adhesive interlining were prepared as experimental samples. Criteria and characteristics for assessing jacket appearance were investigated in sensory tests. A paired comparison of the jacket appearance was conducted using a ranking method. Smoothness and constriction values were proposed and obtained using three-dimensional shape data. The smoothness value refers to the degree of wrinkling on the jacket surface and the constriction value refers to the degree of constriction of the waistline. A quantitative assessment model of jacket appearance was proposed using multiple regression analysis. Findings – The sensory test reveals that the number of wrinkles, acceptability of wrinkling and degree of constriction of the waist are important criteria in the assessment of jacket appearance. The smoothness value for the front body and the constriction value of the waist partially agreed with the normal scores of sensory test results. Sensory evaluation values for the entire jacket appearance were estimated employing multiple regression analysis with the constriction and smoothness values. The values of jacket appearance estimated using multiple regression analysis were in good agreement with the sensory test results. Originality/value – Criteria and characteristics to be used in the assessment of the appearance of a jacket with adhesive interlining were clarified. Employing the proposed methodology, it is possible to predict jacket appearance for different adhesive interlinings, quantitatively.

Seaweed-Kappaphycus-Euchema Cottonii and Denticulum species was first cultivated at Sabah side of Sebatik in 2009. By November 2014, sixty one Sabahan seaweed farmers cultivated 122 ha or 3,050 long lines. Thirty Sabahan seaweed farmers in Kampung Pendekar (3.2 m.t dried) and 31 in Burst Point (12.5 m.t dried) produced 16 metric tonnes of dried seaweed contributed 31% to Tawau’s total production (51 m.t). The remaining 69% were from farmers in Cowie Bay that separates Sebatik from municipality of Tawau. Indonesian in Desa Setabu, Sebatik started in 2008. However, the number of Indonesian seaweed farmers, their cultivated areas and production (as well as quality) in Sebatik increased many times higher and faster than the Sabah side of Sebatik. In 2009 more than 1,401 households in Kabupaten Nunukan (including Sebatik) cultivated over 700 ha and have produced 55,098.95 and 116, 73 m.t dried seaweed in 2010 and 2011 respectively. There is a divergence in productions from farming the sea off the same island under similar weather conditions. Which of the eight explanatory factors were affecting production of seaweeds in Sebatik? Using Cobb Douglas production function, Multiple Regression analysis was conducted on 100 samples (50 Sabahan and 50 Indonesian). Results; Variable significant at α = 0.05% are Experience in farming whereas Farm size; Quantity of propagules and Location — Dummy are the variables significant at α 0.01%. Not significant are variables Fuel; Age; Number of family members involved in farming and Education level.

The paper examines relation between Vietnam Airline Domestic service quality and customer satisfaction by gathering opinions from 402 passengers employing Skytrax scale with some modification along with Cronbach’s alpha, EFA and multiple regression analysis. Results show that Vietnam Airline Domestic service quality can be measured by the following six determinants in order of decreasing importance: (1) boarding/deplaning/baggage; (2) check in; (3) in-flight services; (4) reservation; (5) aircraft; and (6) flight crew. All of them are directly proportional effect to customer satisfaction. The paper also offers some suggestions to improve the service quality thereby enhancing the customer satisfaction.
