Dishwashing tools such as sponges, scourers, and dishcloths are known to harbor dense and diverse microbial communities, including pathogenic bacteria. In this study, the potential of corona discharge plasma jet (CDPJ) as a disinfectant was tested to improve the hygienic quality of dishwashing tools. For the simulation of microbial contamination, selective pathogenic bacteria (Escherichia coli O157:H7, Staphylococcus aureus, and Pseudomonas putida) were inoculated on selected dishwashing tools (dishcloth, sponge, and scourer) at concentrations of 6.55 to 8.77 log CFU/cm 2 . CDPJ generated at 20 kV voltage and 1.5A current was used for decontamination, whereas a sample-to-electrode distance of 25 mm was maintained during the treatment. Following CDPJ treatment for 5 min, the viable counts of E. coli O157:H7, S. aureus, and P. putida were reduced by 4.30-4.56, 3.71-4.78, and 3.50-3.83 log, respectively. The rates of inactivation were varied among the pathogens, decreasing in the order E. coli O157:H7 > S. aureus > P. putida. Among tested kinetic models, namely log-linear, log-linear with shoulder, and Weibull models, the log-linear with shoulder model was found to be the most suitable model to explain the CDPJ inactivation of the pathogens. In conclusion, CDPJ can be used as a potential sanitizing agent for dishwashing tools.

Currently, domestic seaweed production is about 800,000 tons per year, which is the largest seaweed production in the world after China and Japan. However, most seaweeds (Pyropia ssp, Undaria pinnatifida, Saccharina japonica, etc) are consumed in the form of dried products or hot water extracts, and there are many difficulties in developing various products due to difficulties in the manufacturing process. Through the pulsed electric field treatment device, the extraction efficiency can be expected to increase compared to the convectional hot water extraction. Pulsed electric field technology is a non-heating treatment technology in which high-voltage electric energy is processed into cells in the form of pulses, affecting the potential difference of cell membranes, and performing collapse or perforation treatment. In this study, components such as protein and carbohydrate content were extracted by treating Saccharina japonica with PEF, and compared with the hot water extraction method, As a result of experiment at voltages of 0.7 and 1.5㎸ and pulse duration of 5㎲, the crude protein content increased by up to 42% and the sugar content increased by up to 30% compare to the hot water extraction. Higher efficiency results can be expected through optimization of several parameters that may affect the extraction process.

In the fast food industry, a variety of brands compete for consumer preference and loyalty. However, the factors driving the loyalty, especially in an emerging market need examination. This study adapted Şahin, Zehir and Kitapçı’s (2012) repurchase model to examine the consumer-related (brand experience, preference and satisfaction) and brand-related (brand popularity) factors impacting two dimensions of loyalty (attitudinal and behavioural). Data from 717 emerging market consumers using quantitative methods and a non-probability judgmental sampling, revealed through structural equation modelling that brand preference, satisfaction and popularity influenced behavioural loyalty through attitudinal loyalty.

The purpose of this paper is to provide a critical overview of the use of social marketing in Asia. A total of 17 countries were included in this paper. We demonstrate the development and trends of social marketing in Asia by highlighting prominent and effective cases. Our findings reveal that social marketing practice represents a wide spectrum of topics. However, public policy and education outweigh adoption of social marketing to address social issues. Several barriers influence adoption and effectiveness of social marketing. We highlight a few and recommend strategies to overcome them.

Markets are complex ecosystems consisting of various interconnected actors, in which resources are integrated to co-create value. Said value co-creation within markets can be enhanced by creating higher resource density, hence shaping the market. However, market shaping research predominantly focuses on the activities of market shapers, rather than the equally important roles of other market actors within the ecosystem. While market shapers are instrumental in the process of shaping, this narrow focus fails to consider how all market actors inevitably are influenced or influence the market ecosystem. All market actors exert effort in the value co-creation process, including the process of market shaping. This study therefore explores effort in a market shaping context and examines the effects of effort reduction as a mechanism to facilitate market shaping as it leads to enhanced value creation. This is a conceptual study that uses theory adaptation approach to link the concept of value co-creation, market shaping, and effort. This study offers a conceptual framework and five propositions outlining the role of effort reduction in the value co-creation process with flow on effects to market shaping. The developed conceptual framework indicates how market shapers can enhance resource density and increase value creation by reducing the effort required of other market actors in the value co-creation process. This research offers effort reduction in the value co-creation process as a viable market shaping tactic and extends the focus beyond the focal market shaper to consider the broader context with numerous market actors within it.
