The study aims to assess the current status of sustainable clothing habits from the perspective of consumers. Awareness and management behavior regarding microplastics from fashion products and usage of fleece and faux fur were investigated. A random online survey involving 413 women was conducted to figure out their perceptions on microplastics that are shedded from fashion products such as fleece and faux fur. The results indicate that 73.6% were not aware of the fact that microplastic is released during the washing process of fleece and faux fur. Furthermore, only 26.6% of the respondents who were aware of microplastics from clothing washing were making efforts to reduce its emission. The respondents considered product sustainability more in the selection stage than in the management stage (p<.001). The results revealed that, although the respondents were highly aware of the risk of environmental pollution that microplastics pose, they were neither fully cognizant of the fact that microplastics may come from fashion products, nor did they make efforts to reduce its emissions. Compared with respondents in their 20's, respondents in the age of 30-40 years seemed more aware of microplastics from fashion products and exerted more effort to reduce its emission.

Phospholipase D has great commercial value due to its transphosphatidylation products that can be used in the food and medicine industries. In order to construct a strain for use in the production of PLD, we employed a series of combinatorial strategies to increase PLD expression in Bacillus subtilis WB600. These strategies included screening of signal peptides, selection of different plasmids, and optimization of the sequences of the ribosome-binding site (RBS) and the spacer region. We found that using the signal peptide amyE results in the highest extracellular PLD activity (11.3 U/ml) and in a PLD expression level 5.27-fold higher than when the endogenous signal peptide is used. Furthermore, the strain harboring the recombinant expression plasmid pMA0911-PLD-amyE-his produced PLD with activity enhanced by 69.03% (19.1 U/ml). We then used the online tool \RBS Calculator v2.0 to optimize the sequences of the RBS and the spacer. Using the optimized sequences resulted in an increase in the enzyme activity by about 26.7% (24.2 U/ml). In addition, we found through a transfer experiment that the retention rate of the recombinant plasmid after 5 generations was still 100%. The final product, phosphatidylserine (PS), was successfully detected, with transphosphatidylation selectivity at 74.6%. This is similar to the values for the original producer.

Objective: The aims of this study were to select one strain of Lactobacillus plantarum (L. plantarum) for a potential indigenous safe starter culture with low level antibiotic resistant and low biogenic amine production and evaluate its effect on biogenic amines reduction in Moo som. Methods: Three strains of indigenous L. plantarum starter culture (KL101, KL102, and KL103) were selected based on their safety including antibiotic resistance and decarboxylase activity, and fermentation property as compared with a commercial starter culture (L. plantarum TISIR543). Subsequently, the effect of the selected indigenous safe starter culture on biogenic amines formation during Moo som fermentation was studied. Results: KL102 and TISIR 543 were susceptible to penicillin G, tetracycline, chloramphenicol, erythromycin, gentamycin, streptomycin, vancomycin, ciprofloxacin and trimethoprim (MIC90 ranging from 0.25 to $4{\mu}g/mL$). All strains were negative amino acid-decarboxylase for lysis of biogenic amines in screening medium. For fermentation in Moo som broth, a relatively high maximum growth rate of KL102 and TISIR543 resulted in a generation time than in the other strains (p<0.05). These strain counts were constant during the end of fermentation. Similarly, KL102 or TISIR543 addition supported increases of lactic acid bacterial count and total acidity in Moo som fermentation. For biogenic amine reduction, tyramine, putrescine, histamine and spermine contents in Moo som decreased significantly by the addition KL102 during 1 d of fermentation (p<0.05). In final product, histamine, spermine and tryptamine contents in Moo som inoculated with KL102 were lower amount those with TISIR543 (p<0.05). Conclusion: KL102 was a suitable starter culture to reduce the biogenic amine formation in Moo som.

High viscosity carbon black dispersions are used in various industrial fields such as color cosmetics, rubber, tire, plastic and color filter ink. However, carbon black particles are unstable to heat due to inherent characteristics, and it is very difficult to keep the quality of the product constant due to agglomeration of particles. In general, particle size analysis is performed by dynamic light scattering (DLS) during the dispersion process in order to select the optimum dispersant in the carbon black dispersion process. However, the existing low viscosity analysis provides reproducible particle distribution analysis results, but it is difficult to select the optimum dispersant because it is difficult to analyze the reproducible particle distribution at high viscosity. In this study, dynamic light scattering (DLS) and asymmetrical flow field-flow fractionation (AsFlFFF) analysis methods were compared for reproducible particle size analysis of high viscosity carbon black. First, the stability of carbon black dispersion was investigated by particle size analysis by DLS and AsFlFFF according to milling time, and the validity of analytical method for the selection of the optimum dispersant useful for carbon black dispersion was confirmed. The correlation between color and particle size of particles in high viscosity carbon black dispersion was investigated by using colorimeter. The particle size distribution from AsFlFFF was consistent with the colorimetric results. As a result, the correlation between AsFlFFF and colorimetric results confirmed the possibility of a strong analytical method for determining the appropriate dispersant and milling time in high viscosity carbon black dispersions. In addition, for nanoparticles with relatively broad particle size distributions such as carbon black, AsFlFFF has been found to provide a more accurate particle size distribution than DLS. This is because AsFlFFF, unlike DLS, can analyze each fraction by separating particles by size.

Purpose: As consumers have difficulty in brand choice due to excessive information, using brand popularity as an advertising cue (e.g., Sales No. 1, Hit Product) has been getting more attention as an effective curation strategy for decreasing consumers' cognitive efforts. Accordingly, recent studies empirically demonstrate that consumers tend to prefer and choose a brand with a popularity cue and offer a useful information regarding how to use a popularity cue in marketing communication. However, extant research has mainly focused on investigating the impact of "brand popularity in a domestic market" on consumer behaviors. Thus, little is known about the effect of "brand popularity in a foreign market" on local consumers' decision-making process. Given that domestic consumers tend to purchase imported products from overseas countries, it can be meaningful information for global companies. Therefore, this research derives and tests the five hypotheses to examine how local consumers respond to brand popularity in a foreign market as an advertising cue. Specifically, it tests the three hypotheses regarding the direct and indirect effects of brand popularity in a foreign market on risk perception and purchase intention. Then, it tests two additional hypotheses about moderating effects of psychic distance on the relationship between brand popularity and risk perception as well as on the relationship between brand popularity and purchase intention. Seventy participants are exposed to an advertisement for an Indian cosmetic brand using a popularity cue in Indian market and answer the questions about brand evaluation. For data analysis, regression analysis is employed. The findings of this research show that perceived brand popularity lowers local consumers' perceived risk with a foreign brand. However, perceived brand popularity does not have a direct impact on purchase intention while it has an indirect effect through perceived risk. Meanwhile, psychic distance moderates the effect of perceived brand popularity on perceived risk level, but it has no impact on the relationship between brand popularity and purchase intention. This research is one of the first studies that demonstrate the positive impact of brand popularity in a foreign market on a local consumer's purchase decision, and it shows the effect can be moderated by psychic distance.
