Waist Circumference predicting Cardiovascular Disease in Korean Men and Women

Objective: Obesity and cardiovascular disease (CVD) are closely related and have become increasingly prevalent in Korea. Asians are more prone to obesity-related co-morbidities than Caucasians, even at lower body mass index (BMI) and/or smaller waist circumference (WC) values. Nevertheless, little is known regarding the association of WC with the risk of CVD in non-Caucasian populations. The authors conducted a prospective cohort study of WC and the risk of CVD in the Korean Heart Study.Methods: We examined the association of WC to CVD incidence among 53,026 Korean adults (30,152 men, 22,874 women) with no history of CVD and/or cancer. During a mean follow-up of 8.6 years, 2,722 incident cases of atherosclerotic cardiovascular disease (ASCVD) including 1,383 cases of ischemic heart disease (IHD) and 1,012 cases of stroke were documented. Results: Average WC at baseline was 84.0±8.2 cm in men and 75.2±8.9 cm in women. After adjustment for age and BMI, WC was significantly associated with cardiovascular risk factors (P <.001). In men, a WC of ≥91 cm was associated with an ASCVD hazard ratio (HR) of 1.62 (95% confidence interval (CI): 1.25, 2.10) and an IHD HR of 1.70 (95% CI: 1.19, 2.42) in comparison with a WC of <78 cm even after further adjustment for BMI and traditional risk factors (P for trend = 0.0118, 0.0139 respectively). In women, the progressive associations of WC with ASCVD, IHD and stroke were observed. These associations were however attenuated after further adjustment for BMI and traditional risk factors. The multivariable HRs for ASCVD, IHD, and stroke increased with higher WC in both men and women. Conclusions: Central obesity significantly and independently contributes to cardiovascular outcomes in Korean men and women

Effects of Online Consumer Reviews on Attitudes and Behavioral Intentions toward Products and Retailers

The purpose of this dissertation is to examine the role of consumer reviews in consumers’ decision making process. The current study aims to help researchers and practitioners understand how consumers process different type of information in online consumer reviews. The specific research objectives are to examine (1) how different type of online consumer reviews influence consumers’ responses toward the reviews (2) how different types of individual characteristics influence consumer processing of the content of the reviews, and (3) how consumers’ responses evoked by review content affect consumer attitudes and behavioral intentions toward the reviewed products and retailers. This study addressed two aspects of review-type: (1) type of product information in online consumer reviews (attribute-and-benefits reviews vs. benefits-only reviews), and (2) type of personal information disclosed by the reviewers (reviewers’ personal information vs. reviewer stories). The literature reviews guided the development of hypotheses and the model of the study in an online apparel store context. To test the hypotheses, this study employs an online experiment with a mock website. A total of 425 participants collected from consumer panels of marketing research firm were used for the analyses. The analyses revealed that reviews containing reviewers’ consumption stories, compared to those containing reviewer information, produce more positive thoughts, greater perceptions of reviews’ informativeness, and more favorable attitudes toward the reviews. Contradicting the predictions, there was no moderating effect of individual differences in chronic tendency to enjoy thinking and engage in thinking. Participants’ responses evoked by the reviews showed positive relationships with their attitudes and behavioral intentions toward the reviewed product and the retailer. Further discussion about the results, implications, and suggestions for future research are provided

User Experience in Fashion Brand Pages in Social Networking Sites: Values and Affective Experience of Information Interaction

To enhance a current understanding about brand pages in SNS, this study focuses on user experiences during information interactions in brand pages in SNS and investigates how different values of information interactions in brand pages influence affective experiences, which in turn affect users\u27 experiential states (satisfaction, engagement, cognitive elaboration) and thus their loyalty intention toward brand pages. Four facets of values of interest include two instrumental values (perceived control and usefulness) and two non-instrumental values (perceived enjoyment and connectedness). Data were obtained from 290 adult Koreans who followed fashion brand SNS pages using a self-administered online survey. Our results indicate that users\u27 affective experience during information interaction plays a key role in generating positive user experiences with brand pages in SNS. Specifically, affective experience enhances satisfaction, engaging experience, and cognitive elaboration, thereby increasing loyalty intentions toward the brand page. Additionally, perceived controllability, usefulness, and enjoyment create affective experience

The Impact of Brand-endorser Image Congruence on Chinese Consumers’ Attitudes and Behavioral Intentions toward Luxury Fashion Brands

While an influencer marketing is one of the popular social marketing activities in China, luxury brands’ collaborations with digital influencers sometimes lead to criticism due to a lack of image fit between influencers and brands. In order to have an enhanced understanding of how image fit leads to consumer responses toward marketing activities and brands, the current study examines whether the perceived fit between a luxury brand and a digital influencer influences consumers’ satisfaction with the collaboration, their brand attitudes, their likelihood to recommend the collaboration and purchase intention. A web-based survey was administered to Chinese consumers. The findings of the study confirm the role of perceived fit in generating positive responses toward the collaboration and the brand. The findings imply that, while luxury brands can leverage influencer marketing, brand marketers are recommended to consider the image fit between their brand and digital influencers since a poor fit may cause the dilution of brand image

ADIPOQ Gene Variants Associated with Susceptibility to Obesity and Low Serum Adiponectin Levels in Healthy Koreans

OBJECTIVES: This study aimed to measure the association between the adiponectin, C1Q and collagen domain-containing (ADIPOQ) gene variants and obesity in Koreans. METHODS: Three single nucleotide polymorphisms located in the ADIPOQ gene were genotyped in a population-based cross-sectional study of 986 healthy Koreans. Three different case-control groups (i.e. G1, G2, and G3) were defined according to body mass index (BMI) and serum adiponectin levels. Allelic and genotypic associations of this gene with obesity were measured using multivariate logistic regression analyses in each group. RESULTS: The G allele of -11377C>G, a polymorphism located in the promoter region of the ADIPOQ gene (odds ratio (OR), 1.48; 95% confidence interval, 1.13-1.94) and most haplotypes including this allele significantly increased the risk for obesity. However, the OR decreased from 3.98 (G1 group) to 2.90 (G2 group) and 2.30 (G3 group) when a less strict definition of obesity was used. Most haplotypes, including this allele, significantly increased the risk of obesity. The statistical evidence from the GG genotype of -11377C>G (OR, 3.98) and the GT/GT diplotype composed of -11377G>C and +45T>G (OR, 5.20) confirmed the contribution of the G allele toward a predisposition for obesity. CONCLUSION: These results suggest the contribution of the ADIPOQ gene toward susceptibility to obesity in healthy Koreans. The high-risk genotypes and haplotypes identified here may provide more information for identifying individuals who are at risk of obesity.ope

Successful Use of Newspapers in Curriculum Development for First-year College Students

The course, Fashion and Society, is designed to provide first-year Clothing and Textiles major students with an integrated view of fashion as social phenomenon. From the survey on the first-year students’ perceptions about fashion, we have found that many students considered fashion tend to be irrelevant, something fancy and distant to their daily life, and difficult to understand. Based on the comments, we need teaching materials that can be perceived to be “not difficult” (and fun) and relevant. We also needed to design the course to provide students opportunities to apply their knowledge to real life. Thus, we developed the course using several newspapers to help students experience various fashion expressions and reflections a society carries in

Adiponectin is Associated with Impaired Fasting Glucose in the Non-Diabetic Population

OBJECTIVES: Adiponectin is strongly associated with diabetes in the Western population. However, whether adiponectin is independently associated with impaired fasting glucose (IFG) in the non-obese population is unknown. METHODS: The serum adiponectin, insulin resistance (IR), and waist circumference (WC) of 27,549 healthy Koreans were measured. Individuals were then classified into tertile groups by gender. IFG was defined as a fasting serum glucose of 100-125 mg/dL without diabetes. IR was calculated using the homeostasis model assessment of insulin resistance (HOMA-IR). The association of adiponectin and IFG was determined using logistic regression analysis. RESULTS: WC and adiponectin were associated with IFG in both men and women. However, the association of WC with IFG was attenuated in both men and women after adjustment for the HOMA-IR. Adiponectin was still associated with IFG after adjustment for and stratification by HOMA-IR in men and women. Strong combined associations of IR and adiponectin with IFG were observed in men and women. Multivariate adjusted odds ratios (ORs) (95% confidence interval [CI]) among those in the highest tertile of IR and the lowest tertile of adiponectin were 9.8 (7.96 to 12.07) for men and 24.1 (13.86 to 41.94) for women. CONCLUSION: These results suggest that adiponectin is strongly associated with IFG, and point to adiponectin as an additional diagnostic biomarker of IFG in the non-diabetic population.ope

Molecular characterization of tetracycline- and quinolone-resistant Aeromonas salmonicida isolated in Korea

The antibiotic resistance of 16 Aeromonas (A.) salmonicida strains isolated from diseased fish and environmental samples in Korea from 2006 to 2009 were investigated in this study. Tetracycline or quinolone resistance was observed in eight and 16 of the isolates, respectively, based on the measured minimal inhibitory concentrations. Among the tetracycline-resistant strains, seven of the isolates harbored tetA gene and one isolate harbored tetE gene. Additionally, quinolone-resistance determining regions (QRDRs) consisting of the gyrA and parC genes were amplified and sequenced. Among the quinolone-resistant A. salmonicida strains, 15 harbored point mutations in the gyrA codon 83 which were responsible for the corresponding amino acid substitutions of Ser83→Arg83 or Ser83→Asn83. We detected no point mutations in other QRDRs, such as gyrA codons 87 and 92, and parC codons 80 and 84. Genetic similarity was assessed via pulsed-field gel electrophoresis, and the results indicated high clonality among the Korean antibiotic-resistant strains of A. salmonicida

Short-Term Clinical Observation of Acute Retinal Pigment Epitheliitis Using Spectral-Domain Optical Coherence Tomography

We investigated the case of a young man with blurred vision in his left eye. His visual acuity was slightly decreased, and ophthalmoscopy disclosed a gray-white lesion in the macula. He had no systemic or ocular history. On the visual field test, the threshold sensitivity was decreased in the corresponding region. Spectral domain optical coherence tomography (OCT) demonstrated a disruption in the photoreceptor inner and outer segment (IS/OS) junction and undulation of the retinal pigment epithelium (RPE) with backscattering. We re-examined the patient after two weeks and after three months without any treatment. Visual acuity and visual field results were gradually normalized, and OCT demonstrated the recovery of continuity in the photoreceptor IS/OS junction, as well as decreased RPE irregularity with minimal backscattering. We used spectral domain OCT instead of time domain OCT (OCT3) so that we could provide better image resolution of the acute retinal pigment epitheliitis (ARPE). Finally, we observed recovery of the functional and anatomical changes in the ARPE patient with a resolution of the condition within three months following the initial examination, using OCT and visual field tests
