        Activated carbon (AC) injection has been regarded as one of the most effective control technologies for Hg0 removal in flue gas. It is worthwhile to explore new and simple preparation methods for AC with low cost and high Hg removal capacity. In this study, a biomass based AC was successfully prepared from levant cotton exocarp using ZnCl2 activation. The mercury adsorption efficiency and mechanism were studied via the fixed bed experiments. Activator, reaction temperature and components of simulated coal-fired flue gas were investigated. Brunauer–Emmett–Teller (BET), scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM–EDX) and X-ray photoelectron spectroscopy (XPS) were applied for morphology characterization of the prepared AC and discussion of the possible adsorption mechanism. The adsorbed mercury species and the physiochemical properties of prepared AC were discussed. The results showed that (1) Hg0 removal efficiency could reach up to 90% at 150 ℃ under simulated flue gas (SFG); (2) Hg0 adsorption was controlled by the combination of physical and chemical mechanisms.

        This study examined the causal relations among brand personality, brand identification, and brand equity of Korean SPA brands that target Chinese consumers. Data were collected from 600 Chinese consumers residing in Beijing and Shanghai from August 15th to August 30th of 2015 by using convenience sampling; 561 of the questionnaires were used in the statistical analyses. Structural equation models were employed using AMOS 22.0. The results were as follows. First, the factors of Korean SPA brand personality, such as sophistication, competence, tenacity, and interest, exerted significant influences on the brand identification, while honesty had no significant influence on brand identification. Second, brand identification had significant influence on brand awareness, brand image, and brand loyalty. Third, brand awareness showed significant influence on brand image and brand loyalty. Fourth, brand image had significant influence on brand loyalty. These results indicated that brand equity can be strengthened by enhancing brand identification with the proper brand personality. This demonstrates that if Chinese consumers can associate Korean SPA brands with a sophisticated, attractive image, brand identification may be improved and brand equity may be strengthened in the long run, providing basic data for establishing efficient marketing strategies for Korean SPA brands in the Chinese market.

        residue as the raw material. As one of the preconceived raw material to produce high-quality coal-based carbon material, the changes of structure of CLP during liquid-phase carbonization process have been detailed investigated in this study. Actually, FTIR and curve-fitted method were used to quantitative analyze the aromaticity index (Iar), the ratio of CH3/ CH2, and basic functional groups (C=C, C=O, and C–O) of CLP and its liquid-phase carbonization products. Polarizing microscope, XRD and curve-fitted methods were used to characterize the microstructures of CLP and derived products. The results show that, branched chain and C=O group are the active reaction point in liquid-phase carbonization process. What’s more, 450 °C is a critical temperature point on the severe thermal polycondensation of CLP. The XRD and curve-fitted analysis of CLP and its liquid-phase carbonization products shows that, the stacking height (Lc), parallel layers (N), and the numbers of aromatic ring in each layer (n) are gradually larger with the improve of liquid-phase carbonization temperature.

        It is becoming increasingly essential for firms to achieve social improvement. Consumers no longer support firms that solely seek profits. A worldwide consumer survey found that 66% of respondents are willing to pay premium prices for brands from firms concerned with social well-being (Nielsen Report, 2015). Therefore, many firms actively engage in various societal marketing activities to elicit positive responses from consumers. As societal marketing continues to increase in importance, many studies have focused on the effect of corporate social responsibility activities. As one such activity, cause-related marketing (CM) is defined as “the process of formulating and implementing marketing activities that are characterized by an offer from the firm to contribute a specified amount to a designated cause when customers engage in revenue-providing exchanges that satisfy organizational and individual objectives” (Varadarajan & Menon, 1988, p.60). This enables a firm to improve its brand image or reputation and increase sales (Henderson & Arora 2010; Pracejus & Olsen 2004). A firm that employs CM can differentiate itself in competitive markets, which leads to increase in consumer’ purchase intention and their willingness to pay more for the firm’s brands (Müller, Fries, & Gedenk, 2014; Strahilevitz, 1999; Winterich & Barone, 2011). Therefore, CM expenditures are predicted to reach 2.06 billion dollars in 2017 (IEG Report, 2016). Further, CM growth continues worldwide in both developed and developing countries (Adkins, 2008; Wymer & Samu, 2009). Therefore, we focus on CM among various societal marketing activities. Many firms conduct CM in markets that differ both economically and culturally. However, cross-country or cultural research on consumers’ responses to CM is scarce. Although some studies consider cultural factors, most are based on Western-Eastern or individualism-collectivism typology (Ralston, et al., 2008; Yuan, Song, & Kim, 2011). It is dangerous to assume a bi-cultural continuum without considering the multiple variations within the Western or Eastern worlds. The current research addresses this limitation in literature, by exploring CM within the Asian market. We specifically examine Korea and China, as these countries are included in Asian culture, but differences exist between the two. The majority of previous research has discovered factors for successful CM, including the donation magnitude and quantifier, product traits (e.g., type, involvement), the company’s characteristics such as reputation or image, and the cause’s familiarity or importance (Barone, Miyazaki & Taylor, 2000; Lafferty, & Edmondson, 2014; Pracejus, Olsen, & Brown, 2003; Samu & Wymer, 2009). The results regarding the product type’s effect on consumer responses toward CM, revealed that guilt received considerable attention. It has been found that guilt generated by hedonic consumption compels consumers to purchase CM products. Further, the consumer regards the product’s CM as a means of justifying their hedonic product purchase. Many studies demonstrate that consumers choose CM products to reduce guilty-feeling regarding consumers simply as beings who seek to maximize utility. However, CM must also be illuminated, as CM is marketing strategy that involves donation. In summary, we take both economic and ethical perspective based on the dual process theory. From an economic view point, we examine the effect of guilt on consumers’ preferences for CM products. We then propose a new factor from an ethical perspective. Further, we study the two factors’ impacts on consumers’ decision-making through a cultural comparison. We conducted a between-subjects experiment. It was found that Korean consumers felt guiltier and the mean of perceived value of CM was higher in Chinese consumers (Table Ⅰ). As the below Figure Ⅰ illustrates, there was significant interaction effect between countries (Korea versus China) and product type (utilitarian versus hedonic). We also confirmed that the underlying consumer response mechanism to CM products differs between Korean and Chinese. These results support prior studies’ conclusions, in that guilt is the key factor in consumers’ decision-making processes regarding hedonic CM products. And we present the value perception as new influential factor. This paper provides several implications. First, we attempt to overcome previous research’s narrow viewpoint toward CM. As research is scarce regarding the ethical or philanthropic aspect of CM, we focus on that aspect with a particular focus on consumers’ perception of CM value. Second, this paper draws on the dual mode theory, to proposes another new influential factor that affects consumer behavior. As dual processes’ relative effects may differ depending on context (Sonenshein, 2007), therefore, and third, this study examines these effects using a cultural context. Korea and China have a substantial ripple effect on the global economy, thus, it is valuable to study the two countries’ different responses toward CM. Finally, our study provides more insight and practical implications for firms in the Korean and Chinese markets.

        Many advanced ground-based solar telescopes improve the spatial resolution of observation images using an adaptive optics (AO) system. As any AO correction remains only partial, it is necessary to use post-processing image reconstruction techniques such as speckle masking or shift-and-add (SAA) to reconstruct a high-spatial-resolution image from atmospherically degraded solar images. In the New Vacuum Solar Telescope (NVST), the spatial resolution in solar images is improved by frame selection and SAA. In order to overcome the burden of massive speckle data processing, we investigate the possibility of using the speckle reconstruction program in a real-time application at the telescope site. The code has been written in the C programming language and optimized for parallel processing in a multi-processor environment. We analyze the scalability of the code to identify possible bottlenecks, and we conclude that the presented code is capable of being run in real-time reconstruction applications at NVST and future large aperture solar telescopes if care is taken that the multi-processor environment has low latencies between the computation nodes.
