This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g−1 and 1.17 cm3 g−1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large mesopores centered at 9.9 nm was observed. The specific capacitance of the reported materials reached up to 328 F g−1, which was 2.1 times higher than that of pristine CMK-3. The capacitance retention rate was found to be higher than 87.9% after 1000 charge/discharge cycles. The supplementary pseudocapacitance as well as the enhanced wettability and conductivity due to the incorporation of nitrogen heteroatoms within the carbon matrixes were found to be responsible for the excellent capacitive performance of the reported NOMC materials.

Wolfiporia cocos is a well-known traditional medicine in China, Japan, Korea, and other Asian countries owing to its numerous therapeutic properties. With the aim to determine the morphology and genetic characteristics of W. cocosten strains of W. cocos were cultivated in vitro, and subsequently, rapid amplification of polymorphic DNA was performed. To the best of our knowledge, this is the first study to examine the morphology of fruit bodies of W. cocos in Korea. W. cocos were cultured on PDA agar at different temperatures (12, 16, 20, 24, and 28oC) under 12-hour light (600 Lux) / 12-hour dark photoperiod condition for 1 month. Appearance of fruit body was the highest at 28°C condition in all the strains investigated. Honeycomb-like structure on sclerotia was observed in Andong 01, Andong 02, Andong 03, KFRI 1104, KFRI 1105, KFRI 1106, KFRI 1107, KFRI 1108, and ASI 13007 strains of . The KFRI 1103 strain formed cosmos petal-like structure on sclerotia. The average size of basidiospores was recorded as 7.55 μm in height and 3.35 μ in width.

We report the use of carrot, a new and inexpensive biomaterial source, for preparing high quality carbon dots (CDs) instead of semi-conductive quantum dots for bioimaging application. The as-derived CDs possessing down and up-conversion photoluminescence features were obtained from carrot juice by commonly used hydrothermal treatment. The corresponding physiochemical and optical properties were investigated by electron microscopy, fluorescent spectrometry, and other spectroscopic methods. The surfaces of obtained CDs were highly covered with hydroxyl groups and nitrogen groups without further modification. The quantum yield of as-obtained CDs was as high as 5.16%. The cell viability of HaCaT cells against a purified CD aqueous solution was higher than 85% even at higher concentration (700 μg mL−1) after 24 h incubation. Finally, CD cultured cells exhibited distinguished blue, green, and red colors, respectively, during in vitro imaging when excited by three wavelength lasers under a confocal microscope. Offering excellent optical properties, biocompatibility, low cytotoxicity, and good cellular imaging capability, the carrot juice derived CDs are a promising candidate for biomedical applications.

Nanofibers(NFs), because of their high surface area and nanosized grains, have appropriate morphologies for use in chemiresistive-type sensors for gas detection applications. In this study, a highly sensitive and selective CO gas sensing material based on Au-decorated SnO2 NFs was fabricated by electrospinning. SnO2 NFs were synthesized by electrospinning and subsequently decorated with various amounts of Au nanoparticles(NPs) by sputtering; this was followed by thermal annealing. Different characterizations showed the successful formation of Au-decorated SnO2 NFs. Gas sensing tests were performed on the fabricated sensors, which showed bell-shaped sensing behavior with respect to the amount of Au decoration. The best CO sensing performance, with a response of ~20 for 10 ppm CO, was obtained at an optimized amount of Au (2.6 at.%). The interplay between Au and SnO2 in terms of the electronic and chemical sensitization by Au NPs is responsible for the great improvement in the CO sensing capability of pure SnO2 NFs, suggesting that Au-decorated SnO2 NFs can be a promising material for fabricating highly sensitive and selective chemiresistive-type CO gas sensors.

We estimate the fractal dimension of the ρ Ophiuchus Molecular Cloud Complex, associated with star forming regions. We selected a cube (v, l, b) database, obtained with J = 1−0 transition lines of 12CO and 13CO at a resolution of 22′′ using a multibeam receiver system on the 14-m telescope of the Five College Radio Astronomy Observatory. Using a code developed within IRAF, we identified slice-clouds with two threshold temperatures to estimate the fractal dimension. With threshold temperatures of 2.25 K (3σ) and 3.75 K (5σ), the fractal dimension of the target cloud is estimated to be D = 1.52–1.54, where P / AD/2 , which is larger than previous results. We suggest that the sampling rate (spatial resolution) of observed data must be an important parameter when estimating the fractal dimension, and that narrower or wider dispersion around an arbitrary fit line and the intercepts at NP = 100 should be checked whether they relate to rms noise level or characteristic structure of the target cloud. This issue could be investigated by analysing several high resolution databases with different quality (low or moderate sensitivity).

Bee pollen have been used for centuries as a kind of traditional medicine and food diets additive due to their nutritional and biological properties. The present study was to evaluate the biological features of ethanol extracts of 18 different bee pollen (EEBP) samples collected from 16 locations of South Korea. Our results indicated most of the EEBP samples showed 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, inhibitory activities against human β-amyloid precursor cleavage enzyme (BACE-1), and antiproliferative activities towards five cancer cell lines. However, these EEBP samples did not present human acetylcholinesterase (AChE) inhibitory activities, and intestinal bacteria growth inhibitory activities.

There is a general consensus in the literature that impulse buying is normatively wrong, but accounts for a substantial volume of the goods sold every year across the broad range of product categories, including fashion products. Research revealed that young consumers particularly contributed greatly to the increase of impulse buying. While lack of self-control has been found strongly associated with the unplanned nature of impulse buying, with an environment of abundance and consumerism, self-indulgence, rather than lack of self-control, may become a more important driver for impulse buying for modern consumers (Sharma, Sivakumaran, & Marshall, 2011). Therefore, the purpose of this study is to investigate how self-indulgence influences young consumers’ impulse buying and the post purchase consumer regret. This study also aims to test the role of fashion consciousness in the relationship between young consumers’ self-indulgence and impulse buying for fashion products. Self-indulgence is considered a hedonistic tendency, which includes enjoying spending money on oneself, buying things for one’s own pleasure, and trying to enjoy life (Sharma, Sivakumaran, & Marshall, 2011). It was recognized as one of the two opposing cognitive forces leading to impulse behavior (Miao, 2011). While the impulse to purchase is comprised of anticipated pleasures and immediate gratification (Rook, 1987), ironically, consumer regret is one of the major emotional consequences associated with impulse buying. There are two types of consumer regret: cognitive dissonance, resulted from an immediate post-purchase comparison of what was purchased versus the other available alternatives, and consumer guilt, related specifically to the consumption decision situations. Literature suggested that individuals show interest in fashion products with the belief that fashion products will contribute to their appearance, image, and/or bring enjoyment to their life (Workman & Kidd, 2000). In that same token, an individual with high self-indulgence tendency is more likely to show interest in fashion in hopes of identifying fashion items for indulgence purpose. Moreover, this indulgence motivated fashion consciousness will more likely lead to high impulse buying for fashion products. Based on the literature, hypotheses were developed for this study as represented in the following figure. Data was collected using a survey of college students majored in textile/fashion management at a large southeast university in the USA. A total of 190 surveys were distributed and returned. The majority of the subjects were females (73.7%), white (74.7%), and held part-time work (56.7%). Existing scales were adopted to measure self-indulgence (Sharma, Sivakumaran, & Marshall, 2011) and fashion consciousness (Bruner & Hensel, 1998). Impulse buying behavior and post-purchase regret were measured by asking subjects to retroactively recall their shopping trips for fashion products during the past three months. A group of items developed by the researchers were used to measure both the impulse buying behavior and consumer regret. A Confirmatory Factor Analysis (CFA) was first employed to assess the psychometric properties of the constructs. Overall, the fit indices of the measurement model were acceptable (NFI=0.86, IFI=0.935, RMSEA=0.066, CMIN/DF=1.7). A Structural Equation Modeling (SEM) was conducted to test the relationship proposed in the hypotheses. To test the mediating effect of fashion consciousness on the relationship between self-indulgence and impulse buying behaviors, a bootstrapping bias-corrected confidence interval procedure was conducted. Overall, the fit indices of the SEM model were acceptable (CMN/df=1.338, NFI=0.90, IFI=0.97, RMSEA=0.044). The SEM results suggested that self-indulgence had a significant influence on impulse buying for fashion products directly and indirectly via fashion consciousness. The impulse purchase behavior had a positive influence on the consumers’ feeling of guilt for the impulse purchase behavior, while no significant influence was found on cognitive dissonance. This research makes several contributions to the literature of impulse buying. First, the study suggests that consumers’ self-indulgence exerts significant direct and indirect influences on consumers’ impulse buying for fashion products. This result may provide an explanation to the phenomenon of increasing impulse buying behavior in the marketplace, even though it is widely considered as a “misbehavior”. Secondly, this study suggests a significant mediating role of fashion consciousness in the relationship between self-indulgence on consumers’ impulse buying for fashion products. The abundance of fashion products in the market and the appreciation of the social and affective function of fashion products contribute to the chain effect from self-indulgence to fashion consciousness and finally to impulse purchase for fashion products. Third, this study confirms the negative guilt feeling resulted from the impulse buying behavior.

Crowdfunding has recently emerged as a novel way for people to collect monetary donation from large numbers of internet users. Since 2009, the volume of crowdfunding has increased exponentially, reaching 16.2 billion in 2014. A growing number of literature starts to investigate social influence in crowdfunding that occurs when former backers, who make contribution to fund a project at an earlier stage of fund-raising period, make influences of the contribution decision of latter backers. Crowdfunding can be classified into four categories, namely, lending-based, equity-based, reward-based, and donation-based. The primary goal of lending-based and equity-based crowdfunding is to raise capital and borrow money from a number of investors or lenders in exchange for interest payment or equity share of a company. In contrast, reward-based crowdfunding or donation-based crowdfunding requires a project initiator to create a project, which raise fund to develop a new product (e.g., private good) or enhance the public interest (e.g., public good). In this study, we focus on the two most popular crowdfunding type: reward-based and donation-based crowdfunding projects. In reward-based crowdfunding, backers (or contributors) give a small amount of money in return for a reward such as a copy of creative work or pre-sell products. In donation-based crowdfunding, backers donate to projects for gratitude and the pleasure of giving and expect no compensation in exchange

This paper aims to contribute to the developing literature of brand attachment and detachment theory, in the context of harsh economic conditions. The Cognitive Appraisal Theory and the Attachment Theory are brought to bear in order to describe and explain consumer shifting patronage decisions.

This research was conducted in order to examine the reverse effect of brand loyalty on the emotional attachment to the place-of-origin. Results indicate that consumers that are highly loyal to a brand tend to be more emotionally attached to the place-of-origin; the effect is mediated by affective place image. Affective place image also partially mediates the brand loyalty–place attachment relationship in cases when the brand is authentic in the place. Human beings tend to extend their affect towards one object based on another object related to the first one. Building on this notion researchers have been trying to understand two related concepts—a place, and a brand originating from that place. In this endeavor, one literature stream has been focusing on place-based branding from the perspective of international marketing, including work on country-of-origin (COO) or product-country image (Baldauf et al., 2009; Hong & Wyer Jr, 1989). Another stream focusing on place branding adapts traditional marketing theory to market a place (Kotler 2002), and focuses on destination image (Bramwell & Rawding, 1996; Lee & Lockshin, 2012; Qu, Kim & Im, 2011), and place attachment (Gross & Brown 2006). Notwithstanding the above, there is a dearth of research combining these two aforementioned streams. One of few exceptions is Lee and Lockshin (2014), who explored the reverse COO effect of product perceptions on destination image. However, they focused on consumers’ cognitive beliefs and, thus, the underlying mechanism of the relationship is yet to be examined. Hence, the current research aims to answer the following questions: can brand loyalty be leveraged to consumers’ relationship with the place-of-origin as a tourism destination? And, if so, what is the mechanism underlying the effect? We present a global survey with consumers of place-based wine brands as a means to understand whether consumers’ loyalty to a brand will influence their emotional attachment to the place where the wine brand origins. A moderated mediation model is proposed. Affective destination image mediates the positive effect of brand loyalty on place attachment, which is positively moderated by authenticity of the brand-place associations. The study contributes to the tourisms marketing field by identifying the emotional linkage between brand loyalty and place attachment. It serves as a starting point for further investigation of how company or product branding could benefit place marketing and branding theory. Affective components are suggested to play a vital role in the relationships between a place and a brand. It further enriches understanding of the role of brand authenticity. Place marketers need to understand the role of brand loyalty in the decision-making process of tourism consumption.

There has been an increasing trend of using code-switching to enhance ad persuasion among local and global brands. Ads that include two or more languages are referred to as code-switched ads (Luna and Peracchio 2005a; 2005b). It is noted that previous studies investigating code-switched ad effectiveness have focused on bilinguals, not monolinguals. Due to the emerging use of code-switching in ads in monolingual markets, more research efforts are required to understand its effectiveness and boundaries among the monolinguals. The purpose of this study is to investigate the moderating role of consumer local-global identity in the effectiveness of code-switched ads among monolinguals. Two experiments were conducted and the results confirmed our hypothesis that consumer local-global identity moderates the effect of code-switched ads. The results indicated that congruence between consumer local-global identity and code-switching enhanced persuasiveness. In addition, the mediating effect of ad involvement was identified. These findings provide managerial implications for marketers.

Carbon source, an essential nutrient for plant growth, mainly includes exogenous sugar and CO2 of the environment in vitro. Therefore, the exogenous sugar and CO2 of the environment make the important roles in tissue culture. The aim of this study is to investigate the effects of different sugar concentrations (0, 10, 15 and 30 g·L-1) on the growth of colored Zantedeschia in vitro under certain CO2 concentration and explore the optimal sugar concentration. The plantlets in vitro of colored Zantedeschia had the largest root number, root weight, and root vigor under 0 g·L-1 (sugar-free culture) treatment. And they had the largest plant height, leaf length and leaf chlorophyll content, but p oor r oot v igor under 3 0 g·L-1 sugar. This study indicated that the optimal condition for proliferation and seedling culture of colored Zantedeschia plantlets in vitro was MS medium with 30 g·L-1 sugar, and the suitable medium for rooting culture and transplanting of colored Zantedeschia was MS medium with sugar-free culture under CO2 enrichment condition.

Background: Strengthening the supraspinatus is an important aspect of a rehabilitation program for subacromial impingement and tendinopathy. Many authors recommended empty-can (EC), full-can (FC), and prone full-can (PFC) exercises to strengthen the supraspinatus. However, no ultrasonography study has yet investigated supraspinatus muscle architecture (muscle thickness; MT, pennation angle; PA, fiber bundle length; FBL) in relation to supraspinatus strengthening exercises. Objects: The purpose of this study was to compare the architecture (MT, PA, and FBL) of the supraspinatus muscle during three different types of exercises (EC, FC, and PFC) using diagnostic ultrasound. Methods: Participants performed three different exercises: (A) EC; the arm was maintained at 60° abduction with full internal rotation in the sitting position, (B) FC; the arm was maintained at 60° abduction with full external rotation in the sitting position, and (C) PFC; the arm was maintained at 60° abduction with full external rotation in the prone position. Ultrasonography was used to measure the MT, PA and FBL of the supraspinatus. One-way repeated analysis of variance with Bonferroni’s post-hoc test was used to compare between the three exercises and the initial position of each exercise. Results: Compared with each initial position, the FC exercise showed the greatest mean difference in muscle architecture properties and the PFC exercise showed the least mean difference. Conclusion: The findings suggest that the FC exercise position may have an advantage in increasing the amount of contractile tissue or producing muscle power and the PFC exercise position may be useful in a rehabilitation program because it offers the advantage of maintaining the muscle architecture properties.

The use of wine vessel Measure words in ancient Vietnamese inscriptions is very complicated. These characters are some examples which are recorded wine vessel quantifier in ancient Vietnamese inscriptions, such as, yu (􄘃)􀉾yu (􂙪)􀉾yu (􃮚)􀉾yu ( )􀉾yu ( )􀉾bo (􆆣)􀉾bo ( )􀉾bo ( )􀉾 cheng (􂜖)􀉾cheng (􂎉)􀉾xiu (􄻟)􀉾xiu ( )􀉾xiu ( )􀉾xiu ( )􀉾xiu ( )􀉾 xiu (􁼯)􀉾hu (􂠻)􀉾hu (􂠸)􀉾hu (􅀢)􀉾ping (􂚫)􀉾lu (􇿪)􀉾weng (􄑖)􀉾zhai (􆺌)􀉾 zhai ( )􀉾jing (􂫒)􀉾ping (􂞁) and zun (􃥾). Above words are compared and analyzed with the use of wine vessel measure words in Chinese. We found measure word Characters for Vietnamese wine vessel are influenced by China. This kind of phenomena reflects Chinese character being studied imitated and innovated by Vietnamese in the course of spread.
