최근 QoLT(Quality of Life Technology)를 통해 장애인, 노약자 등의 삶의 질을 높이기 위한 기술들이 연구 및 개발되고 있다. 그 중 시각장애인의 경우, 오프라인 쇼핑에 대한 심리적, 신체적 한계로 인한 욕구를 충족하기 위해 음성 안내, 실내 내비게이션 그리고 보조기기에 대한 선행연구가 이루어지고 있으나 아직까지 서비스의 사용성 확보가 이루어지지 않고 있다. 이에 본 연구는 시각장애인의 오프라인 쇼핑 경험에 기반하여 실내 매장 이동을 위한 서비스를 제안하는데 연구 목적을 두고 있다. 본 연구에서 문헌 연구를 통해 시각장애인의 욕구 도출 및 QoLT 수요 시장의 동향 분석에 기반한 문항 설계를 통해 시각장애인 설문조사 및 심층인터뷰 실시하고, 컬처럴 프로브를 진행하였다. 사용자 조사를 통해 퍼소나 설계 및 퍼소나에 따른 아이디어 워크숍을 진행하여 도출된 총 13개의 아이디어를 포지셔닝하여 상위 아이디어를 중심으로 컨셉 브리프를 진행하여 감각적 표현을 통한 정보제공과 의류추천 및 동행 서비스, 자동결제 시스템, 동선안내의 핵심 기능을 통해 자율성과 이동성의 가치를 충족시키는 모빌리티 및 앱 서비스의 프로토타입을 설계하였다. 전문가 평가를 통해 시각장애인의 안전하고 독립적인 이동과 매장 방문 및 상품 구매에 적합한 서비스임을 확인하였고, 최종적으로 시각장애인의 오프라인 쇼핑 경험 개선을 위한 모빌리티 및 앱 서비스와 서비스 시나리오 및 블루프린트를 제안하였다. 본 연구는 시각 장애인 중심의 오프라인 쇼핑 경험에 대한 욕구를 도출했다는 점에서 학문적 의의가 있으며, 모빌리티 및 앱 서비스를 통해 서비스 시나리오를 도출했다는 점에서 실무적 의의가 있다. 이는 향후 시각장애인의 실내 이동기기 시스템 개발에 활용 될 수 있다. Recently, through QoLT(Quality of Life Technology), technologies for improving the quality of life of the disabled and the elderly are being researched and developed. Among them, in the case of the visually impaired, prior studies have been conducted on voice guidance, indoor navigation, and assistive devices to satisfy the desires due to the psychological and physical limitations of offline shopping, but the usability of the service has not been secured yet. Therefore, the purpose of this study is to propose a service for moving indoor stores based on the offline shopping experience of the visually impaired. This study designed mobility and application prototypes that meet the value of autonomy and mobility through service concept briefs for improving offline shopping experience for visually impaired people, clothing recommendation and accompanying services, automatic payment systems, and core functions of route guidance. Expert evaluation confirmed that the service is suitable for safe and independent movement and store visits and purchase of products for blind people, and finally proposed mobility and app services and service scenarios and blueprints to improve offline shopping experience for blind people. This study is of academic significance in that it derived a desire for offline shopping experience centered on the visually impaired, and is of practical significance in that it derived service scenarios through mobility and app services. This can be used to develop indoor mobile device systems for blind people in the future.

SUSTAINABLE FASHION CONSUMTION BEHAVIOR THROUGH THE ANALYSIS OF CONSUMER TYPES - FOCUSED ON A Q METHODOLOGY AND PURCHASE PERCEPTION MATRIX -

Sangah Song,Eunju Ko 글로벌지식마케팅경영학회 2014 Global Marketing Conference Vol.2014 No.7

The fashion industry, being energy and labor-intensive, has faced obstacles such as waste of resources, environmental pollution, and poor working conditions through the supply chain process. Because of the huge success of fast fashion, the consumption of fashion products has increased by 60% in the past ten years. At the same time, the problem of clothing waste is rearing its ugly head accounting for more than 30% of the entire garbage of the world. Providing clothes in cheaper price causes a poorer working condition. In April 2013, a deaths of 1,149 people in garment factory of Bangladesh is caused by the poor working condition without safety standard. Considering its direct effect on lives, consumers are now asking fashion companies to take on more social responsibilities and sustainability is emerging as a critical issue in the fashion industry (Ko, Hwang, & Kim, 2012; Yoo, 2012a). However despite consumers’ high interest in sustainability, they hardly ever seemed to connect with actual consumers according to various studies. Therefore, for a better understanding of consumers to foster their sustainable purchase behavior, this study attempts to identify consumers’ perception and attitude toward sustainable fashion and provide a suitable promoting strategy for consumer types. The role of consumers in driving a sustainable industry ecosystem is growing in importance, but few studies on sustainable fashion consumers have been conducted. Besides, there are two unsolved limitations, in particular, which have been pointed out multiple times in previous studies: first, the inconsistency between the findings (D’Souza, Taghian, Lamb, & Peretiatko, 2007; McDonald & Oates, 2006; Moisander, 2007; Peattie, 2001; Rex & Baumann, 2007; Straughan, 1999), and second, the failure to explain “the attitude-behavior gap.” (Kollmuss & Agyeman, 2002; Vermeir & Verbeke, 2006; Yoo, 2012b) In this context, this study employs Q methodology and purchase perception matrix to identify consumers. Q methodology is more effective and robust technique than self-report methods for the measurement of attitudes and subjective opinion (Stanton & Guion, 2010; Cross, 2005). And the purchase perception matrix, proposed by Peattie (1999), is known as a useful model to classify individual sustainable purchase (Peattie, 1999; Peattie, 2001; McDonald & Oates, 2006; Tan, 2011). The matrix combines two dimensions (High vs. Low confidence and compromise) to analyze four potential purchases such as win-win purchase, feeling good purchase, why not? purchase, why bother? purchase. Peattie’s matrix implies the concept of purchases but also has resonance with the concept of consumers. For example, using marketing strategy to enhance confidence and reduce compromise of each consumer makes their sustainable purchases more easy (McDonald & Oates, 2006). This study tests four types of benefit cueing using advertisement stimuli on sustainable fashion in order to suggest an effective promoting strategy to consumers. Moon et al. (2013) investigate three benefits of sustainable fashion, which are altruistic benefit (out-directed and selfless), social image benefit (out-directed and self-interested) and self-oriented benefit (inner-directed and self-interested). Hartmann et al. (2005) test two types of marketing strategy which are emotional strategy (a feeling of happiness by altruistic behavior or expression of self-identity as a green consumer) and functional strategy (excellent performance in eco-friendly function). Following the previous studies, this study investigates 2 (benefit orientation: external-oriented, internal-oriented) by 2 (benefit type: rational, emotional) benefit cueing stimuli into different types of consumer to verify four hypotheses such as first, external-oriented benefit is more effective than inner-directed benefit (Kim and Kim, 2002; Park, Oh, and Hwang, 2013). Second, based on the purchase perception matrix, high confidence and compromise consumer is more affected than low confidence and compromise consumer by external-oriented benefit. Third, high confidence and compromise consumer is more affected by external-oriented plus rational benefit (Pahbar and Wahid, 2011). And fourth, low confidence and compromise consumer is more affected by external-oriented plus emotional benefit (Vermeir and Verbeke, 2006). In study 1, Q methodology is conducted to identify the types of sustainable fashion consumer with 26 participants. As the result, four types of consumer are identified; the doubtful egoist, the single-minded bystander, the wavering intellect, and the narcissistic activist. The doubtful egoist is especially interested in personal gains and distrusts so-called sustainable fashion. The single-minded bystander has his own subjective opinion on sustainable fashion and is not easily persuaded by sustainable marketing messages. The wavering intellect is obviously interested in sustainability but also shows the highest attitude-behavior gap. The narcissistic activist sets great store by his social image and for that reason consumes sustainable fashion products. In study 2, which aims to verify the four types of consumer and test different types of benefit cueing of sustainable fashion by surveying 328 participants. Each consumer type is shown to be distinctive in terms of sustainable fashion perception, sustainable fashion behavior, fashion lifestyle, cost and benefit perception of sustainable fashion, and the degree of confidence and compromise. The four types of consumer are categorized into two types based on the purchase perception matrix. The wavering intellect is located on higher degree of confidence and compromise position but the others are on an opposite side by showing lower degree of confidence and compromise. Four types of benefit cueing are suggested to two types of consumer (the degree of confidence and compromise: high, low) with regard to the consumer types’ willingness to pay for sustainable fashion. The result shows that external-oriented benefit is more effective than internal-oriented benefit (Mex=2.84, SDex=.079, Min=2.46, SDin=.093; F=9.435, p<.005, H1 is supported). Those who show high degree of confidence and compromise are affected by external-oriented benefit than low degree of confidence and compromise consumers (Mh=3.19, Ml=2.49, F=12.130, p<.005; H2 is supported) and most of all, external-rational benefit (Mex-e=3.18, Sdex-e=.85, Mex-r=3.95, Sdex-r=1.18; t=2.351, p<.05, H3 is supported). Those who show low degree of confidence and compromise are affected by external-emotional benefit but this difference did not fall within the range of statistical significance (Mex-r=2.38, Sdex-r=1.24, Mex-e=2.61, Sdex-e=1.05; t=1.176, p>.05, H4 is rejected). This study theoretically contributes to a new and holistic perspective of sustainable fashion consumer and provides better understanding by Q methodology and purchase perception matrix. This study investigates the complex attributes of benefit such as different types and orientations and it takes a step-by-step look at how different benefit cueing leads actual behavior change of consumer. Especially, this study adopted a new variable such as consumer type and it enhances the feasibility of predicting sustainable fashion acceptance of each type of consumer. From a practical point of view, this study will be useful for offering guidelines to identify a specific target to generate a specific result for sustainable fashion company. For instance, concentrating on altruistic benefit promoting strategy with fluent information about eco-friendly attributes and socially responsible activities can strengthen high degree of confidence and compromise consumers who are relatively easy to change purchase behavior and regarded as target consumers. But those strategy does not much affect to low degree of confidence and compromise consumer who are potential consumers and as well as mass consumers in terms of their actual numbers in market. It is needed a long-term approach and in such context, this study offers guidance for expanding sustainable fashion from a niche market to a mass market.

Sangah Jeong,Byung Joo Song,Jiyoung Rhu,Cheolki Kim,Sun Im,Geun-Young Park 대한재활의학회 2021 Annals of Rehabilitation Medicine Vol.45 No.5

Objective To investigate the prevalence and risk factors of axillary web syndrome (AWS) in Korean patients. Methods This retrospective study included a total of 189 women who underwent breast cancer surgery and received physical therapy between September 2019 and August 2020. We analyzed AWS and the correlation between the patients’ demographics, underlying disease, type of surgery and chemotherapy or radiation therapy, and lymphedema. Results The prevalence of AWS was found to be 30.6%. In the univariable analysis, age, chemotherapy, and hypertension were related to AWS. Finally, the multivariable logistic regression revealed that chemotherapy (odds ratio [OR]=2.84; 95% confidence interval [CI], 1.46–5.53) and HTN (OR=2.72; 95% CI, 1.18–6.30) were the strongest risk factors of AWS. Conclusion To the best of our knowledge, this was the first study that explored the risk factors of AWS in a Korean population after breast cancer surgery. As almost one-third of patients suffer from AWS after breast cancer surgery, it is essential to closely monitor the development of AWS in patients with hypertension or undergoing chemotherapy.

Evidence-based approaches for establishing the 2015 Dietary Reference Intakes for Koreans

Sangah Shin,Subeen Kim,Hyojee Joung 한국영양학회 2018 Nutrition Research and Practice Vol.12 No.6

BACKGROUND/OBJECTIVES: The Dietary Reference Intakes for Koreans (KDRIs), a set of reference intake values, have served as a basis for guiding a balanced diet that promotes health and prevents disease in the general Korean population. In the process of developing DRIs, a systematic review has played an important role in helping the DRI committees make evidence-based and transparent decisions for updating the next DRIs. Thus, the 2015 KDRI steering committee applied the systematic review framework to the revision process of the KDRIs. The purpose of this article is to summarize the revision process for the 2015 KDRIs by focusing on the systematic review framework. MATERIALS/METHODS: The methods used to develop the systematic review framework for 2015 KDRIs followed the Agency for Healthcare Research and Quality and the Tufts Evidence-based Practice Center. The framework for systematic review of the 2015 KDRIs comprised of the 3 following steps: (1) development of an analytic framework and refinement of key questions and search terms; (2) literature search and data extraction; and, (3) appraisal of the literature and summarizing the results. RESULTS: A total of 203,237 studies were retrieved through the above procedure, with 2,324 of these studies included in the analysis. General information, main results, comments of reviewers, and results of quality assessment were extracted and organized by study design. The average points of quality appraisals were 3.0 (range, 0-5) points for intervention, 6.1 (0-9) points for cohort, 6.0 (3-9) points for nested case-control, 5.4 (1-8) points for case-control, 14.6 (0-22) points for cross-sectional studies, and 7.0 (0-11) points for reviews. CONCLUSIONS: Systematic review helped to establish the 2015 KDRIs as a useful tool for evidence-based approach. Collaborative efforts to improve the framework for systematic review should be continued for future KDRIs.
