This study investigated consumers' multi-channel behavior for fashion product purchases and compared perceived risks by channel type. A survey involving male and female college students was conducted in the Daegu and Gyungbuk area in December 2013. A total of 400 responses were analyzed using descriptive statistics, chi-square analysis, independent sample t-test, paired t-test, factor analysis, and reliability analysis. An internet shopping mall was the most frequently chosen retailer type for fashion product purchases and information searches. In addition, respondents also preferred independent branded stores, department stores, and non-branded stores. The number of retailer types for clothing item purchases ranged from 1 to 6 and the average was 3.06. The number of retailer types was significantly higher in women groups according to gender variables. Perceived risk had the highest evaluation score for internet shopping malls. Department stores were recognized as a reliable retailer type. The construct of perceived risk was shown as similar in off-line stores such as department stores, independent branded stores, and non-branded stores. Instead, the construct was differentiated from the case of internet shopping malls. Some insightful suggestions were suggested for future research and industrial marketing plans based on the results.

The purposes of this study were to find out any significants among somatotypes and face types and importance of image making to successful students' life. The respondents were composed of 181 males and 160 females. It consists of total 29 items including the facial features, personality expression methods, characteristics of body shapes, image making, colors and neckline and their responses were measured with Likert 5-point scale. For data analysis, descriptive statistics, cross-tabulation analysis including $Χ^2$-test and frequency analysis were used. As the results, 47％ of male students and 28% of female students responded they were satisfied with their own facial types. 32% of male students and all female students were not satisfied with their own body shapes and fashion depends on accessories like hat, sunglasses, boots and necklace rather than dress itself. All male and female students were not satisfied with their body shapes and recognized the importance of image. They answered that they change image if someone advices their image and it suggests that information and intellectual needs of image making are required and approach to efficient methods of image making is needed.

This study was undertaken to investigate the different responses of cultured plant cells to paraquat treatment and nucleus-DNA damage in relation to enzyme activity of superoxide dismutase (SOD). Furthermore, this study was also carried out to understand the antioxidative mechanism of plant cells to environmental stress. We selected two different species of plant cultured cells, Ipomoea batatas as high-SOD species and Lonicera japonica as low-SOD species. The total activity and specific activity of SOD in a chlorophyllous cell of I. batatas were 3,736 unit/gㆍfresh weight and 547 unit/mgㆍprotein, respectively, and those in L. japonica were 23 unit/gㆍfresh weight and 13 unit/mgㆍprotein, respectively SOD activity in chlorophyllous I. batatas cells reached its maximum level at 10 to 15 days after subculture, whereas that in L. japonica remained at a very low SOD level during the whole period of subculture. In comparison to L. japonica, I. batatas, a high-SOD species, showed high tolerance to paraquat 10 and 50 mg/l treatment in terms of cell viability and electrolyte leakage. Based on the result of comet assay, the nucleus-DNA damage of two species by paraquat 50 mg/l treatment was not significantly different. However, I. batatas cells repaired their damaged DNA more effectively than the cells of the low-SOD species, L. japonica.

Objectives : The aim of this study was to investigate the degree of awareness of the national cancer screening program by the Korean public and define its relationship with cancer screening intention. Methods : The study collected data by conducting an online survey from April 19 to 24, 2016, and received a total 354 responses. Additionally, we performed frequency analysis, chi-square test, and logistic regression analysis. Results : Based on the results for the degree of awareness for the national cancer screening program, 151 (42.7%) people were aware of the program, while 203 (57.3%) were not aware the program. From the chi-square test and logistic regression analysis, marital status and awareness of the national cancer screening program were found to have a statistically significant influence on screening intention. Conclusions : An increase in the screening rate should be established with a systematic promotion plan for the national cancer screening program.

The main purpose of this study was to determine the influence of brand and country-of-origin on consumers' perception of apparel products. $2\times2$ between subjects factorial design with brand (no brand vs. prestigious brand) and country-of-origin (Italy vs. Korea) was used. Consumer ethnocentrism and product involvement were included as covariates in analyzing the data. The stimuus was a double-breasted v-neckline beige jacket. All the labels were removed and a label indicating one of the four brand/country-of-origin conditions was attached. The participants' perception of the jacket was measured in terms of product attitude, product evaluation, purchase intention and expected price. A total of 205 housewives participated in the field experiments conducted in front of four moi or department stores in Seoul, and 202 responses were used in the final analysis. There was no significant difference in product attitude, product evaluation and purchase intention according to brand or country-of-origin. But brand, country-of-origin and the interaction between the variables were significant in explaining the differences in expected price. Consumer ethnocentrism was significant in all the models, while product involvement was significant only in the case of product evaluation. The relationships among demographic variables, consumer ethnocentrism and product involvement were also examined.

This study predicted consumer approach/avoidance behavior through consumer emotional experiences and examined the moderating effect of perceived surprises in the context of digital signage in store environments. A self-administered questionnaire consisted of consumer emotional experience (e.g., pleasure, arousal, and dominance), approach-avoidance behavior and perceived surprise by digital signage. A total of 278 usable responses were obtained from consumers who experienced digital signage at fashion retail stores. The findings support the Mehrabian-Russell model in the context of digital signage. Approach behavior was predicted by pleasure and arousal emotional experience, while avoidance behavior was predicted by dominance. The moderating effect of perceived surprise was also indicated in the effect of emotional experience on approach or avoidance behavior. In the high level of perceived surprise, pleasure and arousal had significant effects on approach behavior, whereas dominance had significant effect on avoidance behavior. This study discussed theoretical and managerial implications for creating emotional experiences and developing strategic store management by utilizing new digital technology within the fashion retail environments.

The purposes of this study are to (1) explore the characteristics of consumers who purchase products designed by rising fashion designers, and (2) examine the effects of consumer fashion innovativeness and price consciousness on consumer responses toward the products (i.e., product innovativeness, perceived value, and purchase intention). A total of 469 adult consumers aged 19 to 59 responded to an online survey that consisted of a stimulus (i.e., news article introducing new brands of rising fashion designers) and measurement items. As a result, 20% of respondents are found to be customers of rising fashion designers. These buyers (vs. non-buyers) are characterized as female, high income, and high interest toward rising fashion designer products. The findings from structural equation modeling show that fashion innovativeness and price sensitivity have significant, positive effects on product innovativeness and perceived value that further increase purchase intention. These relationships are significant in terms of perceived value dimensions, except for the relationship between social value and purchase intention. Both fashion innovativeness and price sensitivity have significant and positive effects on social, emotional, economical, and functional values. The emotional, economical, and functional values also have significant, positive effects on purchase intention. The implications of these findings are discussed in the conclusion.

The goal of this study is to investigate the factors affecting firefighter's traumatic experiences and to examine and compare the differences of how those factors contribute to firefighter's burnout, depression, anxiety and social relationships. This study suggests that it is imperative for firefighters to have mindfulness, which brings mental and emotional healing, for their job-satisfaction. To empirically examine the research model of this study, the questionnaire survey was carried out to firefighters in InCheon Metropolitan City for two weeks; from October 19thto November 3rd, 2017. Out of 180 questionnaires, 170were retrieved. Total number of 160 questionnaires are empirically examined this study, excluding10bad survey responses. The t-test was conducted to determine whether there exist differences by gender among traumatic experienced firefighters, and a meaningful difference was found from perceived intrusiveness, a sub factor to traumatic experiences. Male firefighters showed higher mean than that of female firefighters in perceived angle, evasion and intrusiveness. Second, the t-test was conducted to determine whether there exist differences by gender in firefighter's burnout, but no meaningful differences were found. Female firefighters showed higher mean in emotional exhaustion, impersonalization and in decrease in self-achievements. Third, the t-test was conducted to determine whether there exist differences by gender in firefighter's depression and relationships, but no meaningful differences were found.

When the speed of a coaxial rotor helicopter in forward flight increases, the wake skew angle of the rotor increases and consequently the position of the vena contracta of the upper rotor with respect to the lower rotor changes. Considering ambient air and the effect of the upper rotor, this study proposes a nonuniform inflow model for the lower rotor of a coaxial rotor helicopter in forward flight. The total required power of the coaxial rotor system was compared against Dingeldein's experimental data, and the results of the proposed model were well matched. A plant model was also developed from first principles for flight simulation, unknown parameter estimation and control analysis. The coaxial rotor helicopter used for this study was manufactured for surveillance and reconnaissance and does not have any stabilizer bar. Therefore, a feedback controller was included during flight test and parameter estimation to overcome unstable situations. Predicted responses of parameter estimation and validation show good agreement with experimental data. Therefore, the methodology described in this paper can be used to develop numerical plant model, study non-uniform inflow model, conduct performance analysis and parameter estimation of coaxial rotor as well as other rotorcrafts in forward flight.
