This study examines consumer reaction to different luxury advertising information (promotion-focus vs. prevention-focus). Studies examine the relationship between consumers’ face concern and individual regulatory focus, and explore the relationship between face concern and luxury advertising type with a 2 (face concerns) × 2 (advertising information) experiment design.

To improve the accuracy of forecasting the peak period of Dendrolimus punctatus, stationary time series, periodic distance method, stepwise regression model and the Bayes discriminant analysis were used. RSME value, kappa coefficient and accuracy were used as evaluation criteria to predict the peak period for the second generation egg of D. punctatus with over 33 years from 1983 to 2016 in Qianshan County, Anhui Province. The predictions of these models were verified in 2017 and 2018. The prediction of the stationary time model and Bayes discriminant analysis for 2017 was one level lower than the actual result and for 2018 was one level higher than the actual result, while the prediction of the periodic distance method was identical to the actual result for 2017 and greatly different from the actual result for 2018. The accuracy for stationary time series (RMSE = 0.92 kappa = 0.76) and periodic distance method (RMSE = 2.96, kappa = 0.81) from 1983 to 2018 were 87.88% and 85.71%, respectively. When taking into consideration the standard error was based on differential, the accuracy for the prediction of stepwise regression model (RMSE = 0.25, kappa = 1.00) from 1983 to 2018 was 100%. The accuracy of Bayes discriminant method (RMSE = 0.71, kappa = 0.96) was 97.14%. Comparatively speaking, the stepwise regression model and Bayes discriminant analysis method were better than the stationary time series and periodic distance method in RMSE value, kappa coefficient and accuracy. So they were relatively ideal forecast methods.
A Variational Framework for Single Image Dehazing Based on Restoration
( Dong Nan ),( Du-yan Bi ),( Lin-yuan He ),( Shi-ping Ma ),( Zun-lin Fan ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.3
The single image dehazing algorithm in existence can satisfy the demand only for improving either the effectiveness or efficiency. In order to solve the problem, a novel variational framework for single image dehazing based on restoration is proposed. Firstly, the initial atmospheric scattering model is transformed to meet the kimmel`s Retinex variational model. Then, the green light component of image is considered as an input of the variational framework, which is generated by the sensitivity of green wavelength. Finally, the atmospheric transmission map is achieved by multi-resolution pyramid reduction to improve the visual effect of the results. Experimental results demonstrate that the proposed method can remove haze effectively with less memory consumption.

We present here the case of a 40-year-old woman with a greater than 10 year prior history of bilateral breast silicone injection and saline bag implantation. Bilateral palpable breast nodules were observed, but the ultrasound scan was suboptimal and the magnetic resonance imaging showed no gadoliniumenhanced tumor. The 18F-FDG PET/CT scan showed a hypermetabolic nodule in the left breast with a 30% increase of 18F-FDG uptake on the delayed imaging, and this mimicked breast cancer. She underwent a left partial mastectomy and the pathology demonstrated a siliconoma.

Aim: The risk factors mostly strongly associated with gastric cancer are gastric bacteria Helicobacter pylori and diet. Using a case-control study among residents in Jinan, we examined the association between the salt taste and gastric cancer according to H. pylori infection, smoking and histological type as well as tumor site. Methods: This population-based case-control study included 207 cases and 410 controls. Data on potential risk factors of gastric cancer were obtained by interview of cases and controls with a questionnaire, salt taste preference was measured for all subjects, and IgG antibodies to H. pylori were applied to assess infection. Risk measures were determined using unconditional logistic regression. Results: The proportions of salt taste at intervals of 1.8-7.2 g/L and ${\geq}7.2$ g/L were significantly higher in cases than controls, with ORs of 1.56 (1.23-3.64) and 2.03 (2.12-4.11), respectively, subjects with high salt intake having an elevated risk for gastric cancer when infected with H. pylori. Significant modification by smoking and tumor site was observed across the different measures of salt intake, the highest salt taste showed higher cancer risk in ever smokers or with non-cardia cancers. Conclusion: Our study supports the view that high intake of sodium is an important dietary risk factor for gastric cancer, with a synergistic effect found between salt and H.pylori and smoking, dependent on the tumor site.
The Fate of <SUP>15</SUP>N-labeled Organic Materials Applied to Chinese Cabbages Cropping System

Nitrogen added to farmland is used to plants or remains in soil, or is lost to environment. We incorporated <SUP>15</SUP>N-labeled materials (Chemical fertilizer (CF), green manure (GM), livestock compost (LC), GM+LC, and oil cake (OC) to soil and cultivated Chinese cabbages (Brassica rapa subsp. pekinensis) and analyzed the <SUP>15</SUP>N recovery of crop and soil to investigate the fate of nitrogen. The results follow. The <SUP>15</SUP>Ncrop recovery of chemical fertilizer (CF) was the highest, and that of organic materials differed by type. The <SUP>15</SUP>Nsoil recovery of CF was the lowest, and that of organic materials was 3 - 6 times higher than CF. The <SUP>15</SUP>Nloss was not significantly difference between CF and organic materials (except GM+LC). As results, despite of the same amount of nitrogen input, there was the difference in plant uptake and soil residue between organic materials and CF. Nitrogen of CF is used to Chinese cabbages more than organic materials, however most of the remaining nitrogen is estimated to be lost to the environment. Therefore, CF might be hard to occur residual effect in the next cropping season. In organic materials, nitrogen is less used to Chinese cabbages than CF, but remains in soil more than CF. Therefore, organic materials might be useful for improving soil fertility and have a residual effect in the next cropping season. We suggest that these properties of organic materials should be taken into account in calculating the amount of applied fertilizer in organic farming where mainly organic materials are used. Moreover, it is necessary to investigate the cumulative and residual effects of continuous input of the same organic materials.

A new complex [Ni(phen)(C9H8Br2NO3)2·2CH3OH·2H2O] [phen: 1,10-phenanthroline C9H8Br2NO3: 3,5- dibromo-L-tyrosine] was synthesized and characterized by IR, elemental analysis and single crystal X-ray diffraction. X-ray crystallography shows that Ni(II) ion is six-coordinated. The Ni(II) ion coordinates with four nitrogen atoms and two oxygen atoms from three ligands, forming a mononuclear Ni(II) complex. The crystal crystallizes in the Orthorhombic system, space group P21212 with a = 12.9546 Å, b = 14.9822 Å, c = 9.9705 Å, V = 1935.2 Å, Z = 1, F(000) = 1008, S = 0.969, ρcalcd = 1.742 g·cm−3, μ = 4.688 mm–1, R1 = 0.0529 and wR2 = 0.0738 for 3424 observed reflections (I > 2σ(I )). Theoretical study of the title complex was carried out by density functional theory (DFT) method and the B3LYP method employing the 6-3l+G* basis set. The energy gap between HOMO and LUMO indicates that this complex is prone to interact with DNA. CCDC: 908041.
