Objectives : Cue reactivity is a key factor that modulates motivational goal-directed behavior associated with compulsive drug-taking and relapse. We investigated whether acupuncture attenuated the skin conductance response and the heart rate response to smoking-related visual cues in smokers. Methods : Twenty-nine smokers were treated with real acupuncture (RA) or sham acupuncture (SA). The stress response inventory was measured on the 5th day after quitting smoking. The skin conductance response and the heart rate were measured to evaluate the autonomic changes to the smoking related visual cues on the same day. Results : The sympathetic alterations in skin conductance and the heart rate induced by the smoking-related visual cues were significantly lower in the RA group, as compared to the SA group. The stress response inventory, such as somatization and frustration, in the RA group was significantly lower than that of the SA group. Conclusions : Acupuncture ameliorated the stress symptoms as well as the sympathetic activation to smoking cues during withdrawal. These findings indicate that acupuncture might be a useful tool in smoking cessation by inhibiting smoking cues-induced autonomic responses.

In monocular images that are used to determine the depth of the vanishing point, the buildings, roads and buildings, such as outdoor video or hallway with room inside for the interior structure, such as the vanishing point in the video is a very strong depth cue. Depth map using the vanishing point in the three-dimensional space, the two-dimensional imaging is used to restore the structure. But if there is a vanishing point vanishing point in the video also depends on the location of the relative depth of different ways to express that need. In this paper we present images of a vanishing point with respect to the improved depth-map was created. Proposed an area where the loss of seven points and areas defined as areas along the proposed direction of different depth.

Purpose: As the visual expression cue that can easily reveal and imprint the brand image to consumers becomes more important, franchise coffee shops are making various efforts to establish design elements and brand identity. Therefore, the purpose of this study is to examine the structural model between design elements, brand identity, brand association, brand personality, and brand image of franchise coffee shops from various angles, and to suggest a plan for using visual elements makes a brand image on the franchise in the future. Research design, data, and methodology: This study tests the structural relationship between design elements, brand identity, brand association, brand personality, and brand image of franchise coffee shops. design elements are divided into three attributes (interior design, product design). And brand identity is divided into two attributes (brand name, brand symbol/logo). In order to achieve the purposes of this research, research model and hypotheses were developed based on previous researches. All constructs were measured with multiple items developed and tested in the previous studies. The data were collected from 380 customers who visited franchise coffee shops and were analyzed through SPSS 26.0 and SmartPLS 3.0 statistical package program. Result: As a result of this study, first, it is confirmed that product design has a positive effect on brand association toward coffee shops. Second, interior design and product design have a positive effect on brand personality. Third, all brand identity have a significant positive impact on brand association and brand personality. Finally, brand association and brand personality of coffee specialty shops have a positive effect on brand image. Conclusions: The following implications of this study are as follows. This study is confirmed that there is an effect of design elements attributes and brand identity attributes on brand association and brand personality. And, the brand image was found to be influenced by brand association and brand personality. This suggests that it can be used to establish visible marketing strategies for franchise coffee shops. Therefore, it is necessary to further improve efforts to raise the level of the brand image through visual factors such as unusual interior design, product packages.

Korean stops are currently undergoing a tonogenetic sound change, as found in the Seoul dialect in which a merged VOT of aspirated and lax stops induces F0 to be the primary cue for distinguishing the two stops and the lax stops have lower F0 than the aspirated stops. In tonal languages, low tone is produced with a breathy voice. This study investigated whether there are changes in voice quality with respect to the tonogenetic sound change of Korean stops. Two age groups speaking the Seoul dialect participated in this study: five females and six males born in the 1940s and 1950s and nine females and eight males born in the 1980s and 1990s. This study replicated previous findings of VOT and F0 and further examined H1-H2, H1-A1, and H1-A2 to see how they correlate with the sound change. In the older and younger generations, H1-H2, H1-A1, and H1-A2 were significantly lower after the tense stops than after the aspirated and lax stops, but they were not significantly different after the aspirated and lax stops. However, the younger females exhibited some different results for H1-H2 and H1-A2 than the older generation. In the younger females, the H1-H2 mean was higher after the aspirated stops than it was after the lax stops at the vowel onset, and the H1-H2 difference increased at the vowel midpoint. Although there was an inter-speaker variation in the results of H1-H2 and H1-A1, analyses of individual speakers showed that the H1-H2 and H1-A1 were higher after the lax stops than after the aspirated stops in the younger female speakers. These results indicate that lax stops tend to be breathier than aspirated stops in the younger female speakers. They also indicate that changes in voice quality are on Korean stops with tonal sound change, but are still developing.

The current study examined the moderating effect of visual cues in eWOM on the relationship between perceived risk and purchase intention. Specifically, the study tested the different directions of the moderating effect in positive and negative eWOM. Two studies from a 2 (perceived risk: high vs. low) by 2 (visual cue: presence vs. absence) experimental design were used with online subjects. Findings from study 1 (n=123) supported that visual cues in positive eWOM help to reduce the negative effect of perceived risk on purchase intention. However, study 2 (n=122) showed that visual cues in negative eWOM intensify the negative effect of perceived risk on purchase intention. The findings demonstrated that visual cues in eWOM influence consumers' decision under high risk conditions. We discussed findings of this study how visual cues in positive and negative eWOM can be strategically managed for new online sellers.

Most corporations engage in Corporate Social Responsibility (CSR) activities. Consumers are aware of CSR activities in different domains and use the perception and evaluation in purchase decision making. This study reveals how the relationship between consumer perception about a fashion corporation's CSR activities and product evaluation (such as perceived expertise and attractiveness) affects behavioral intention. This study discussed implications for store designs depending on whether it is actively engaging in CSR communication. Two virtual fashion store images of modern or eco design were used as stimuli. The study was conducted from July to August, 2018 based on women in their 20s and 30s. We collected 154 eco designs and 157 modern design responses. The findings of the study show that consumer perceptions of CSR activities affected perceived expertise and attractiveness. Further, perceived expertise and attracti-veness led to purchase intention and time spent in the store. The store design variation had no differences in mean values of consumer perception; however, evaluation and purchase intention indicated that a varied store design emphasized different corporation capabilities.

BACKGROUND: Bioprinting has recently appeared as a powerful tool for building complex tissue and organ structures. However, the application of bioprinting to regenerative medicine has limitations, due to the restricted choices of bio-ink for cytocompatible cell encapsulation and the integrity of the fabricated structures. METHODS: In this study, we developed hybrid bio-inks based on acrylated hyaluronic acid (HA) for immobilizing bio-active peptides and tyramine-conjugated hyaluronic acids for fast gelation. RESULTS: Conventional acrylated HA-based hydrogels have a gelation time of more than 30 min, whereas hybrid bio-ink has been rapidly gelated within 200 s. Fibroblast cells cultured in this hybrid bio-ink up to 7 days showed >90% viability. As a guidance cue for stem cell differentiation, we immobilized four different bio-active peptides: BMP-7-derived peptides (BMP-7D) and osteopontin for osteogenesis, and substance-P (SP) and Ac-SDKP (SDKP) for angiogenesis. Mesenchymal stem cells cultured in these hybrid bio-inks showed the highest angiogenic and osteogenic activity cultured in bio-ink immobilized with a SP or BMP-7D peptide. This bio-ink was loaded in a three-dimensional (3D) bioprinting device showing reproducible printing features. CONCLUSION: We have developed bio-inks that combine biochemical and mechanical cues. Biochemical cues were able to regulate differentiation of cells, and mechanical cues enabled printing structuring. This multi-functional bio-ink can be used for complex tissue engineering and regenerative medicine.

Vibration is a mechanical cue that can be applied to adipose tissues for the purpose of treating obesity. However, the exact correlation between vibration and other anti-adipogenic pathways, such as development of cytoskeleton and apoptosis, remains unknown. The objective of this study was to investigate the unknown anti-adipogenic effects of vibration with varied frequencies on preadipocytes. 3T3-L1 preadipocytes were cultured in Dulbecco's modified Eagle's medium (DMEM) containing 5% calf serum at 37 ℃ with 5% CO2 in a humidified incubator. Vibration was generated using Arduino Uno microcontroller and vibration motor module with 1 V DC, and applied to preadipocytes for 3 days. Frequency conditions were set to 20, 55, and 90 Hz. Then, the expressions of p38 pathway, ROCK-1, α-actinin, Bax, Bcl-2, caspase-9, 8, and 3 were analyzed with western blot. As a result, p38 pathway was inhibited in 55 and 90 Hz while ROCK-1 and α-actinin were expressed in 20 Hz. Caspase-3, a terminal apoptotic factor, was activated in 20 Hz via extrinsic pathway rather than intrinsic pathway. Results suggest that various frequencies of vibration can inhibit adipogenesis via different pathways which sheds light on future mechanotransduction applications of vibration for the treatment of obesity.

This study examined the impact of perceived volume on satiety using 400 g kimchi fried rice in a normal rice bowl (Normal-400), 300 g kimchi fried rice in an augmented rice bowl with an elevated bottom (Illusion-300 and 300 g kimchi fried rice in a normal rice bowl (Normal-300). Thirty-six healthy women took part in this study once a week for three weeks. The Normal-400 (1st week), Illusion-300 (2nd week), and Normal-300 (3rd week) bowls were used to served kimchi fried rice to the same participants over three consecutive weeks. After each lunch, the consumption volume of fried rice, perception volume, and satiety rate were measured. The consumption volume of the fried rice was 313.8 g with the Normal-400, 248.9 g with the Illusion-300 and 240.2 g with the Normal-300. The perceived volume on an estimated five-point scale was 4.0 with the Normal-400, 4.1 with the Illusion-300 and 2.4 with the Normal-300. We compared the post-meal satiety of perceptually equal but quantitatively different amounts of food served in two different bowls (Normal-400 vs Illusion-300) and found that the participants felt equally full with both bowls despite having consumed significantly more food from the Normal-400. We also compared the post-meal satiety of perceptually different but quantitatively equal amounts of food in two different bowls (Illusion-300 vs Normal-300) and discovered that the subjects felt significantly fuller with the Illusion-300 although similar amounts of food were consumed from the two bowls. These two comparisons showed that visual cues play a critical role in determining satiety and that perceived volume is perhaps more important than the actual volume of consumed food, while in determining the level of fullness.
