Every year consumers spend billions of dollars on impulse purchases across the globe. Noticeably, occasions for impulse buying have been expanding due to new technologies and the growth of e-commerce that enhanced both the consumer’s accessibility to products and the ease of purchase transactions (e.g., one-click purchase) (Strack and Deutsch 2006). For instance, the retail store have become ubiquitous—being present on our desktop, in our mailbox, on our phone, in subway platform, in gas station kiosks—and reaching every street corner in our neighborhood. Such ubiquitous nature of mobile commerce combined with the introduction of IT devices (e.g., smartphones, tablets) makes consumers even more vulnerable to the sudden, powerful, and persistent urge to buy something instantly (i.e. impulse buying) (Rook 1987; Watson et al. 2002; Danaher et al. 2015). From the perspective of firms, this indicates that marketing opportunities to influence shopper attitudes and behavior can emerge at any point in the shopping cycle from the couch in a person’s living room to the shopping cart in mobile devices and media (Shankar et al. 2010; 2011). While impulse buying has been a well-known approach to explaining empirical deviations from the rational choice model in the literature (Strack et al. 2006), previous researchers have mainly focused on antecedents of impulsive behaviors, such as mood (Rook and Gardner 1993), self-construal (Zhang and Shrum 2009), chronic goals (Ramanathan and Menon 2006) and consumers’ self-loneliness (Sinha and Wang 2013). However, relatively little has been studied on what factors drive consumers to purchase products impulsively and how firms can utilize marketing activities (e.g., 4Ps) to engage consumers in such behavior. There exist a few studies paying attention to the interaction of individual characteristics and marketing variables for impulse buying (e.g., Bell et al. 2010; Inman et al. 2009; Narasimhan et al. 1996) but several issues still can arise from measurement problems, self-selection, lack of marketing variables, and limited breadth of product categories. In particular, researchers have used the term ―unplanned‖ purchases exchangeably with impulse purchases despite a conceptual distinction between the two terms: impulse buying is defined with three key components; unplanned, difficult to control, and resulting in emotional response (Rook 1987). In other words, mostly all impulse purchases are unplanned, but not all unplanned purchases are impulse buys and we cannot rule out other alternative explanations (e.g., it is a ―reminder‖ purchase based on true needs). In this study, therefore, we aim to differentiate two terms and investigate the consumers’ impulsive purchase behaviors using the actual behavioral data with respect to product characteristics, customer demographics, timing and controllable marketing activities such as advertising. We obtained the data from one of the leading TV shopping channels in Korea on 2,657 products and 17,848 air time slots covering a broader range of both hedonic and utilitarian products including electronics, food, fashion, home appliances, and so on (7.8 million orders and 2 million order cancels). Unlike typical supermarket shopping where consumers can actively search products, programming on TV shopping channels are shown randomly to viewers which helps us rule out self-selection problems. Most importantly, distinct from previous studies, we use an objective measure for impulse buying by exploiting the actual order placement and subsequent order cancellation (i.e., regret with retrospective judgment about purchase decisions). We find that product characteristics are the primary factors explaining the half (60.5%) of impulse purchase ratio variations followed by marketing variables (20.4%), and timing fixed effects (10.9%). Interestingly, we find little evidence of consumer demographics (1%) as a driver for impulsive buying behavior. Consequently, we focus on the interplay between product categories and marketing activities. Specifically, we classified the product categories into utilitarian and hedonic on the basis of the gross product categories and investigated the roles of two main marketing activities: advertising and price promotion. We find that the informative and persuasive roles of advertising (Akerberg 2003; Mehta et al. 2004) lead to a U-shaped effect on impulse purchases over time as the informative role attenuates over time but the persuasive role increases over time. While utilitarian products are more likely to be influenced by informative role of advertising and hedonic goods are more likely to be influenced by persuasive role of advertising, we detect that the U shape would be moved to the left (right) with a price discount (increase). In other words, price information does not change over time but the persuasive role increases over time with a price discount. Hence, our results can provide managerial insights for retailers and manufacturers to utilize point-of-sale marketing tactics and to improve their shopper engagement strategies to trigger impulse purchases.

The O2 and CO2 concentrations in controlled atmosphere (CA) rooms are determined by the respiration of produce like apples and the airtightness of the CA room, with gas in the CA room controlled by O2 and CO2 removal as well as respiration (CO2 increase and O2 decrease). The purpose of this study was to evaluate the validity of the gas exchange model for O2 removal, CO2 removal, the rate of O2 decrease and CO2 increase by respiration of apples, and airtightness of the CA room. It took 17.5 hours to reduce O2 concentration from 20.9% to 2.0% after loading 4.3 tons of Fuji apples into the CA room, which was 4.2 hours longer than the 13.3 hours of the model formula. After the CO2 concentration rose to 0.5% due to respiration, it took 4.7 hours to lower the CO2 concentration to 0.2%, which was 0.6 hours longer than that of the model equation. The rate of CO2 increase by respiration was 0.021%/ h, which was similar to the model equation (0.017%/h). Also after 4.7 hours, the O2 concentration decreased by 0.1% which was also in line with the model equation (0.13%/h).

In the United States and Europe, new environmentally friendly asphalt pavement has been researched as an alternative to traditional hot asphalt pavement. After the Paris Convention of 2015, policies should be found to reduce carbon dioxide. In the field of asphalt pavement, new methods are needed to reduce carbon dioxide from the traditional hot asphalt pavement. In Korea, waste asphalt is growing and natural aggregate is running dry. So the government is implementing policies to increase the use of waste resources. So, it created a new asphalt pavement method to reduce CO2 and use waste asphalt. It is a cold recycled asphalt pavement. Emulsified asphalt has a balance of dispersibility, stability, and adhesive between water, aggregates, and asphalt. But, the physical properties of emulsified asphalt can be degraded compared to traditional hot asphalt pavement. So there are limitations in actual use. The study compared the softening point, elastic recovery, and penetration properties of asphalt mix compounds by using latex in emulsified asphalt. In particular, cations latex was used for the emulsified asphalt, which could further improve the physical properties.

Mercury is known as harmful element and significant negative effect on human and living creatures. The current study investigates the effective removal of toxic mercury from aqueous solution by reverse osmosis with low pressure. The various operating conditions as concentration, time and pressure used for the rejection study. The rejection study carried out in both terms as adsorption and pore size for long term (48 h) and achieved 99% mercury rejection. Further, the fouling propensity of membranes was studied and the fouling layer formed on the surface of the membranes was analyzed by the AFM imaging and the flux recovery ratio of the membranes was also calculated. The compatibility, thermal stability, hydrophilicity, surface energy, and morphology of the membranes were systematically investigated.

Mycoplasma (M.) felis and M. canis is related with pneumonia or conjunctivitis in domestic cats and several diseases in a variety of other animals, including lower respiratory tract disease or pleuritis. Polymerase chain reaction (PCR) assays has been reported as an easy and useful method. It could be conducted even on nasal swab samples as a non-invasive rapid testing tools for large numbers of Mycoplasma species. However, PCR assays have to conduct multiple assays because of a lot of Mycoplasma species. Therefore, it need to perform several tests and reveal time consuming procedures. In this study, we developed a sensitive and specific multiplex polymerase chain reaction (PCR) assay that detects simultaneously two species like as M. felis and M. canis. The simultaneous detection of M. felis and M. canis primers were used to differentiate two mycoplasma species. The target DNA fragments were specifically amplified M. felis and M. canis PCR with 16S ribosomal DNA primers. Single and mixed Mycoplasma species DNA templates were submitted to validate the specificity of the multiplex PCR. The corresponding specific DNA products were amplified for each pathogen. The detection limit of the developed multiplex PCR is 102 pg with M. felis and M. canis DNA. Furthermore, the developed multiplex PCR detected successfully M. felis in feline nasal specimens. The multiplex PCR assay provides a novel tool for simultaneous detection and differentiation of M. felis and M. canis in cats.

This study was conducted to propose the conditions of controlled atmosphere (CA) storage suitable for the storage of winter Chinese cabbage and to investigate the maximum storage period of Chinese cabbage based on the results of the quality analysis for CA storage. The weight loss rate of Chinese cabbage stored at 194 days in low temperature storage was about 2 times higher than that in CA storage. The trimming loss rate of Chinese cabbage stored at low temperature was 1.5 times higher than that of CA storage after 83 days of storage. Bolting of Chinese cabbage was observed in only low temperature storage. The Chinese cabbage firmness of CA storage was not different in the range of 5.7-6.2 N, while low temperature storage gradually increased after 83 days of storage and was 7.5 N at 194 days. The incidence of mold occurred after 83 days in low temperature storage, while in CA storage it occurred after 153 days. In the quality evaluation, CA storage for Chinese cabbage was rated 1.5-1.9 points higher than the low temperature storage. The maximum storage period of Chinese cabbage at low temperature storage was 83 days and that at CA storage 153 days.

The electronic and optical characteristics of molybdenum disulphide (MoS2) film significantly vary with its thickness, and thus a rapid and accurate estimation of the number of MoS2 layers is critical in practical applications as well as in basic researches. Various existing methods are currently available for the thickness measurement, but each has drawbacks. Transmission electron microscopy allows actual counting of the MoS2 layers, but is very complicated and requires destructive processing of the sample to the point where it will no longer be useable after characterization. Atomic force microscopy, particularly when operated in the tapping mode, is likewise time-consuming and suffers from certain anomalies caused by an improperly chosen set point, that is, free amplitude in air for the cantilever. Raman spectroscopy is a quick characterization method for identifying one to a few layers, but the laser irradiation causes structural degradation of the MoS2. Optical microscopy works only when MoS2 is on a silicon substrate covered with SiO2 of 100~300 nm thickness. The last two optical methods are commonly limited in resolution to the micrometer range due to the diffraction limits of light. We report here a method of measuring the distribution of the number of MoS2 layers using a low voltage field emission electron microscope with acceleration voltages no greater than 1 kV. We found a linear relationship between the FESEM contrast and the number of MoS2 layers. This method can be used to characterize MoS2 samples at nanometer-level spatial resolution, which is below the limits of other methods.

This study was carried out to investigate insect community structure from different habitats in Baengnyeong island.We performed day and night collection at two different habitats (mountain, rural area) of Baengnyeong island from Mayto September in 2015. A total of 2,879 individuals of 404 species, 81 families belonging to 10 orders were collectedand identified. A dominant species was Idisia ornata Pascoe (Tenebrionidae) despite a very low percentage (6.04%) ofthe species among the catches. Results of independent t-test showed a significant high (p<0.001) of species richness onmountain. Also, seasonal results of ANOVA (Analysis of variance) were significantly influential with species abundanceand species richness. The result of NMDS analysis showed that the community structure of the insects from the mountainis different with rural area.

Although Agaricus bisporus mushroom is a popular mushroom consumed world-widely, the application of common bio-elements to verify its geographical origin remains highly limited. Therefore, this study aimed to verify whether the six cultivation regions in Korea of A. bisporus could be determined by the stable isotope composition analysis of bio-elements, which are unique and abundant in most living creatures. δ13C, δ15N, δ18O, and δ34S in A. bisporus were influenced by the region, cultivar, and the interactions between these two factors (P < 0.05). In particular, the effect of cultivation region was more significant to the isotope ratio profiles as compared to the mushroom cultivar effect. During the cultivation period of A. bisporus, the C, N, O, and S isotopic fractionation was observed between the mushroom and cultivation medium, note higher in the mushroom (P < 0.05). Two dimensional plot of δ15N, δ18O, or δ34S effectively distinguished the cultivation regions, Nonsan, Buyeo, Boryung, Daegu, and/or Gyeongju examined in this study. Further, these isotope ratio profiles measured in this study would be statistically analyzed with various chemometrics to provide isotope markers for the authenticity of geographical origin. Our preliminary case study improves our understanding of how the isotope composition of A. bisporus varies with respect to cultivation regions and cultivars. In conclusion, the analysis of stable isotope ratios is a suitable potential tool for discrimination between the cultivation origins of A. bisporus collected from Korea, with potential application to other countries after certain validation steps required.

As the hangover relieving drink market has been expanded, there have been efforts to produce traditional drinks that can be easily taken through reducing material costs after finding materials with high alcohol-degrading activity from agricultural products and manufacturing drinks in a way to produce sikhye. Studies were made to know quality, the ability to relieve hangover and preference of drinks for which seven kinds of agricultural products, including shiitake mushrooms, were added in the forms of fresh juice, extracts and powder. Farm products showed the highest acetaldehyde dehydrogenase (ALDH) when they were added in the form of powder before saccharification and shiitake mushrooms showed the highest enzyme activity when they were added in the form of powder. When added in the form of powder, people showed the lowest preference except when radish and hericium erinaceum were added. When bear puree was added to a mixture of powdered shiitake mushrooms, radish, bean sprouts and dadagi cucumber, enzyme activity got higher and people showed higher preference. An experiment of animal behaviors showed that the mixture had a high ability to relieve hangover in one or two hours after 10% or 40% alcohol was orally administered to mice due to long traveling distance of mice.
