CHANGING CONSUMER ATTITUDE TOWARDS SUSTAINABLE FASHION: A BALANCE THEORY APPROACH

Eunju Ko,Jinghe Han,Yuri Seo 글로벌지식마케팅경영학회 2016 Global Marketing Conference Vol.2016 No.7

Using a range of interpretive methods, including focus-group interviews, in-depth interviews, and structured field observations, this study investigates how shopping experiences within sustainable fashion stores may cause consumers to change their attitudes towards sustainable fashion. Heider’s balance theory was applied to interpret the results, whereby we constructed the maps of individual consumers’ positive and negative associations of concepts, events, and outcomes within consumers’ purchasing decisions about sustainable fashion products. Our findings suggest that there could often be a gap between the consumer’s perception of sustainable fashion and their actual purchase behavior, which creates an ‘imbalanced’ state. However, positive store experiences may persuade consumers to achieve a balance by purchasing sustainable fashion products. The study provides important and theoretical and practical insights for sustainable fashion marketing

SUSTAINABLE FASHION PRODUCT DEVELOPMENT USING THE PLM APPROACH

Eunju Ko,Jinghe Han,Eunha Chun,Minyoung Lee 글로벌지식마케팅경영학회 2016 Global Marketing Conference Vol.2016 No.7

The ever-evolving fashion industry has brought forth direct and indirect effects on the environmentto the extent that environmental contamination, labor exploitation, and pirated or counterfeit products have emerged as serious social issues. The sustainability-related issues are associated with all stages of the product lifecycle, ranging from the extraction of raw materials to product disposal (Berkhout & Smith, 1999).In lifecycle management (LCM), the triple bottom line (TBL) of sustainability is seen from the perspective of the product lifecycle (Kocmanova & Nemecek, 2009). TBL refers to corporate efforts to keep a balance among financial viability, environmental soundness and social accountability (Elkington, 1997). As sustainable products are defined in the light of lifecycles, research on product lifecycle management (PLM) has drawn much attention (Gmelin & Seuring, 2014).In addition, PLM is known to exert substantial effects on new product development, which warrants the need to view new sustainable products from the perspective of PLM (Cantamessa, Montagna, & Neirotti, 2012). Therefore, the present study intends to apply a conceptual model of PLM-based new sustainable product development to the fashion industry and to take multifaceted approaches to sustainable fashion product development. To that end, case studies of 21 local and global sustainable fashion brands, 1:1 in-depth interviews with 24 experts from sustainable and non-sustainable fashion brands, and participant observation of 5 sustainable fashion brands were conducted as part of this study. The findings illuminate the management issues attributable to the lack of technology and expertise, as well as the quantification issues involving monitoring or normalized data collection, despite the presence of some process-specific sustainable items in sustainable products developed by the fashion brands. Also, the findings will serve as reference data for further discussions and provide some implications for the sustainable fashion product development of fashion brands.

EFFECTS OF VOLUNTARY KNOWLEDGE SHARING OF INNOVATIVE TECHNOLOGY COMMUNITY USERS ON INNOVATIVE BEHAVIORS : FOCUSING ON 3D PRINTING COMMUNITIES

Jinghe Han,Eunju Ko,Hyo Gyeong Kang 글로벌지식마케팅경영학회 2015 Global Fashion Management Conference Vol.2015 No.06

With the recent hype concerning three-dimensional (3D) printing technology, affordable 3D printers have been launched, enabling individual machine owners to download or create design files and thus produce artifacts. As a design community, Shapeways—which comprises over 300,000 members and 25,000 online shops—commercializes and promotes good ideas using 3D printing technology (Shapeways, 2015). Through Thingiverse, people can globally upload and share design modeling files without cost and print out items as desired. In general, 3D printing communities provide data without charges and witness gradually increasing data sharing rates. Literature on 3D printing mainly focuses on cases of technology-related patents, policies, and intellectual property rights. Thus, there is a paucity of empirical studies on 3D printing users. To overcome the limitations of previous studies, this study first builds on both social cognitive and social capital theories to elucidate the effects of 3D printing community users’ self-efficacy; altruistic tendency; and perceived structural, cognitive, and relational capital on their voluntary knowledge sharing and innovative behaviors. Second, it aims to verify inter-group differences in innovative behaviors of 3D printing community users while considering either high or low levels of fashion innovativeness and fashion involvement. For this verification, antecedents of knowledge sharing are elicited from previous research followed by an interview and a questionnaire survey with 3D printing community users to substantiate such antecedents. Next, the data collected from the interview and survey is analyzed using SPSS 18.0. The results indicate that first, altruistic tendencies influence knowledge sharing, which is consistent with the social cognitive theory, whereas structural, cognitive, and relational capitals affect knowledge sharing, which parallels social capital theory. Second, knowledge sharing in 3D printing virtual communities exerts significant effects on innovative behaviors. This study establishes the antecedents and consequences of knowledge sharing in 3D printing virtual communities and proposes a model for effective knowledge sharing, which is projected to stimulate the application of 3D printing technology in creating and sharing fashion design content and providing substantive data for market formation.

Cha, Eunju,Jeong, Eun Sook,Han, Sang Beom,Cha, Sangwon,Son, Junghyun,Kim, Sunghwan,Oh, Han Bin,Lee, Jaeick American Chemical Society 2018 ANALYTICAL CHEMISTRY - Vol.90 No.6

<P>Herein, gas-phase polycyclic aromatic hydrocarbons (PAHs) as nonpolar compounds were ionized to protonated molecular ions [M + H]<SUP>+</SUP> without radical cations and simultaneously analyzed using gas chromatography (GC)/electrospray ionization (ESI)-tandem mass spectrometry (MS/MS). The ionization profile, dissociation, and sensitivity were first investigated to understand the significant behavior of gas-phase PAHs under ESI. The formation of protonated molecular ions of PAHs was distinguished according to the analyte phase and ESI spray solvents. The protonated PAHs exhibited characteristic dissociations, such as H-loss, H<SUB>2</SUB>-loss, and acetylene-loss, via competition of internal energy. In addition, GC/ESI-MS/MS resulted in relatively lower concentration levels (better sensitivity) for the limits-of-detection (LODs) of PAHs than liquid chromatography (LC)/ESI-MS/MS, and it seems to result from the characteristic ionization mechanism of the gas-phase analyte under ESI. Furthermore, the LODs of gas-phase PAHs depended on molecular weight and proton affinity (PA). Consequently, we demonstrated the relationship among the analyte phases, sensitivities, and structural characteristics (molecular weight and PA) under ESI. The gas-phase PAHs provided enhanced protonation efficiency and sensitivity using GC/ESI-MS/MS, as their molecular weight and PA increased. Based on these results, we offered important information regarding the behavior of gas-phase analytes under ESI. Therefore, the present GC/ESI-MS/MS method has potential as an alternative method for simultaneous analysis of PAHs.</P> [FIG OMISSION]</BR>

SHOPPING MALLATTRIBUTES ON CUSTOMER EQUITY

Ting Zhang,Eunju Ko,Jinghe Han,Wei Jiang 글로벌지식마케팅경영학회 2016 Global Marketing Conference Vol.2016 No.7

One of the top tourist destinations in Korea during 2014 was Dongdaemun market, which is a representative traditional market that provides reasonably priced, fashionable products. Already constituting 43.1% of Korea’s foreign tourists, the number of Chinese tourists is expected to reach 14.88 million by 2020 at an average annual growth rate of 19.8%. The most important way to improve customer equity is by understanding a store’s attributes, so this study aims to investigate the effects of Dongdaemun fashion market’s store attributes on customer equity. A survey was conducted among Chinese tourists and structural equation modeling were used to test the hypotheses. The main findings of this study are: Store attributes appear to have an impact on all of the three drivers of customer equity. Value equity has a positive impact on the customer lifetime value (CLV). Also, brand equity and relationship equity were identified as having positive impacts on revisiting intention, regardless of the type of shopping mall. Based on these findings, we discuss implications for developing the customer equity of Dongdaemun’s traditional markets.

Purpose: The purpose of this study is to examine and understand what factors influence the consumers with their practical consumption related tendency to purchase the cosmeceutical products. Method: In this study, the practical consumption related tendency, cosmeceutical perception, and the pur-chase decision making factors were measured as the dependent variables. Results: As a result of the significant study conducted on the purchase related decision making factors, first, it was confirmed that the consumers’ tendency for the practical consumption only during the discounted sales period or they make purchases by comparing the type, price, and the quality of the brands they are interested in. Second, as for the interest in beauty, the UV rays are more related to the skin aging(83%) than the need to consume the beauty related food(69.2%), and the appearance-oriented consumers responded that they are will-ing to undergo cosmetic surgeries if they need cosmetic surgeries(8.8%). Third, the perception of cosmeceuticals demonstrated the preference for natural cosmetics(68.1%) and the scientific evidence(65.9%). Lastly, the decision to purchase cosmeceuticals demonstrated the importance in the order of all ingredients(88.7%), effective-ness(87.6%), eco-friendliness(87.2%), stability(86.8%), and mental effects on the fragrance(84%), respectively. The direct, indirect, and the total effects of cosmeceutical perception were significant as the purchase related decision making factors according to the interest in beauty, and the correlation analytical result and the confirm-atory analysis of the research model were significant as a positive(+) relationship. Conclusion: As a result of such study conducted, cosmeceutical is a word which divides the quality of functional cosmetics, and the producers need to form a market which could commercialize and provide the customer needs, and according to the consumer preferences, capacity, fragrance, ingredients and efficacy, and correlation with skin, the originality and value of the study may be recognized since it has derived the implications for the development of cosmeceutical products which may be positioned through the studies.

A field approach to eradication of porcine epidemic diarrhoea virus in a breeding pig farm: A case-control study

( Eunju Kim ),( Seung-won Yi ),( Sang-ik Oh ),( Kyoung-min So ),( Younghun Jung ),( Han Gyu Lee ),( Joon Ki Hong ),( Eun Seok Cho ),( Young-sin Kim ),( Tai-young Hur ) 한국동물위생학회 2021 韓國家畜衛生學會誌 Vol.44 No.4

Severe outbreaks of porcine epidemic diarrhoea virus (PEDV) have continued to re-emerge worldwide. Because of the high mortality rate of suckling piglets in PEDV outbreaks, the disease causes significant economic losses in the pig industry. The limited pre-existing immunity against this virus is thought to cause an explosive increase in infection in pig farms. This study aimed to evaluate the clinical symptoms of PEDV after intentional exposure (feedback). During the first few days of the outbreak in a breeding pig farm, 14 sows showed watery diarrhoea, and the disease subsequently spread rapidly throughout the barn. Pigs that were intentionally exposed to PEDV (n=251) showed watery diarrhoea (46.6%), reduced appetite (17.5%), and vomiting (6.0%). However, 75 exposed pigs (29.9%) showed no clinical signs of disease. Four weeks after the feedback challenge, 34 sows gave birth to litters of piglets, which survived with no diarrhoea. Five weeks after the start of the outbreak, PEDV was not detected in any of the examined samples, including environmental swabs. Thus, early diagnosis, prompt establishment of herd immunity, and strict application of biosecurity are good practices to reduce the mortality rates among new-born piglets and control economic losses in pig farms showing PEDV outbreaks.

Impaired Extinction of Learned Contextual Fear Memory in Early Growth Response 1 Knockout Mice

Han, Seungrie,Hong, Soontaek,Mo, Jiwon,Lee, Dongmin,Choi, Eunju,Choi, June-Seek,Sun, Woong,Lee, Hyun Woo,Kim, Hyun Korean Society for Molecular and Cellular Biology 2014 Molecules and cells Vol.37 No.1

Inductive expression of early growth response 1 (Egr-1) in neurons is associated with many forms of neuronal activity. However, only a few Egr-1 target genes are known in the brain. The results of this study demonstrate that Egr-1 knockout (KO) mice display impaired contextual extinction learning and normal fear acquisition relative to wild-type (WT) control animals. Genome-wide microarray experiments revealed 368 differentially expressed genes in the hippocampus of Egr-1 WT exposed to different phases of a fear conditioning paradigm compared to gene expression profiles in the hippocampus of KO mice. Some of genes, such as serotonin receptor 2C (Htr2c), neuropeptide B (Npb), neuronal PAS domain protein 4 (Npas4), NPY receptor Y1 (Npy1r), fatty acid binding protein 7 (Fabp7), and neuropeptide Y (Npy) are known to regulate processing of fearful memories, and promoter analyses demonstrated that several of these genes contained Egr-1 binding sites. This study provides a useful list of potential Egr-1 target genes which may be regulated during fear memory processing.
