Application of the FEA consumer needs model in e-commerce: a conversational recommendation system for fashion products

박혜련,Suji Kim,최예림,안효선 한국의류학회 2025 Fashion and Textiles Vol.12 No.1

With the rapid expansion of e-commerce, consumers increasingly rely on online platforms to purchase fashion products. However, the vast selection of products often leads to choice overload, making it challenging for consumers to find products that meet their needs. To address this challenge, we propose an advanced Conversational Recommender System (CRS) that applies a Functional, Expressive, and Aesthetic (FEA) consumer needs model. Using this model as a theoretical framework, this study constructs a taxonomy of consumer needs organized into categories and subcategories, each containing multiple attributes, and uses a Large Language Model (LLM) to apply it to review data, extracting attributes that influence purchase intention. Furthermore, CRS experiments were conducted to assess the impact of consumer needs attributes on recommendation performance. Our results indicate that the FEA model-based consumer needs taxonomy effectively categorizes consumer needs, with ease, good value for money, and leg contouring emerging as the most frequently mentioned attributes. Moreover, consumer needs attributes vary across different pants types, highlighting the importance of need-aware recommendations. Experimental evaluation of the CRS demonstrates that incorporating consumer needs attributes improves the recommendation success rates and reduces the average number of turns. Through the empirical application of the FEA model in the CRS, this study demonstrates its effectiveness in improving recommendation performance and its potential in enhancing consumer satisfaction.

현재의 모든 문서들은 수작업이 아닌 워드 작업으로 이루어진다. 궁금한 것이 있으면 누구나도 자연스럽게 인터넷의 검색창을 떠올린다. 클릭 한 번으로 수만가지의 정보가 쏟아지는 시대이다. 지금을 살아가는데 있어서 없어서는 안 되는 컴퓨터와 인터넷에 대해 사람들의 태도와 반응을 알고자 한다. 2003년 한국 교원대에서 연수 중인 현직 초등학교 교사들을 대상으로 한 설문 조사를 통하여 두려움, 자신감, 호감도, 유용성으로 나눈 컴퓨터·인터넷 사용에 대한 태도와 인터넷, 컴퓨터, 이메일에 대한 자기 효능감에 대한 반응을 성별, 연령, 경력, 전공과목, 최종학력, 컴퓨터 수업 경험, 정보화 교육 연수로 세분화하여 분석해 보고자 한다.

버섯(Lentinus edodes(Berk)Sing) 중의 ATPase에 관한 연구(Ⅰ)

민태진,박혜련 동국대학교 자연과학연구소 1986 자연과학연구 논문집 Vol.6 No.-

표고버섯, Lentinus edodes(Berk) Sing 중의 ATPase를 (NH₄)₂SO₄분별침전 및 Sephadex G-200겔 여과로 정제하였다. 이버섯 중에서 세 종류의 단백질 분획을 얻었으며, adenosine-5'-triphosphate기질에 대한 두 종류의 활성분획 Ⅰ과 Ⅱ를 얻었다. 이 효소는 활성도의 최적 pH는 7.6이었고, 최적온도는 58℃, 열 안정성은 20℃~40℃였다. SDS-PAGE dalton에 의해 측정한 이 효소는 겉보기 분자량은 74,000 dalton이었다. ATPase in the L. edodes was purified by 30% ammonium sulfate saturation and for ? times, by Sephadex G-200 gel filtration chromatography. Three kinds fo rotein fractions were isolated from this mushroom and fraction Ⅰ and Ⅱ showed its activity toward substrate adenosine5-triphoshgate(ATP) Its optimum pH and optimum temperature were found to be pH 7.6 and 58℃, its thermal stabililty was 20℃~40℃. Apparent molecular weight of ATPase was determinded to be 74,000 dalton by SDS-PAGE.

보육교사의 자기 조절력이 임파워먼트와 이직 의도에 미치는 영향

박혜련,김정희 이화여자대학교 이화어린이연구원 2018 영유아교육: 이론과 실천 Vol.3 No.3

본 연구는 보육교사의 개인 변인에 따른 자기 조절력과 임파워먼트, 이직 의도의 차이를 파악하고, 이들 간의 상관관계와 보육교사의 자기 조절력이 임파워먼트와 이직 의도에 미치는 영향을 알아보았다. 연구 대상은 보육교사 288명이며, 수집된 자료는 빈도분석, 백분율, t-test와 일원변량분석(one-way ANOVA), Pearson의 적률상관분석과 다중회귀분석을 사용하여 분석하였다. 연구결과 첫째, 보육교사의 개인적 변인에 따라 자기조절력, 임파워먼트, 이직 의도는 차이가 있었다. 둘째, 자기 조절력과 임파워먼트 간에는 매우 유의미한 정적 상관을 보였으며, 자기 조절력과 이직 의도 그리고 임파워먼트와 이직 의도 간에는 유의미한 부적 상관이 있었다. 셋째, 자기 조절력 하위 요인 중 인지조절력과 메타 인지 조절력 요인이 임파워먼트에 정적 영향을 미치는 것으로 나타났다. 넷째, 보육교사의 자기 조절력 하위 요인 중 정서 조절력 요인이 이직 의도에 부적 영향을 미치는 것으로 나타났다. 이 연구의 결과는 더 효과적인 보육을 위해 보육교사의 자기 조절력을 기초로 보육교사의 임파워먼트를 높이고, 불필요한 이직을 최소화하기 위한 방안을 모색하는 데 필요한 실제적 자료를 제공할 수 있을 것이라 기대한다. The purpose of this study is to investigate the difference of self-regulation, empowerment, and turnover intention according to individual variables of child-care teachers, correlation between them, and the effect of self-regulation of child-care teachers on empowerment and turnover intention. 288 child-care teachers were participated in this study. The data were analysed using frequency analysis, percentages, t-test, one-way analysis of variance(ANOVA), pearson’s correlation and multiple regression analysis. The results of the study are as follows: first, according to the individual variables of the childcare teachers, there were a differences in self-regulation, empowerment, and turnover intention. Second, there was a significant positive correlation between self-regulation and empowerment, and there was a significant negative correlation between self-regulation and turnover intention and empowerment and turnover intentions. Third, cognitive capacity and the meta-cognitive capacity have a positive effect on empowerment. Finally, among the sub-variables of self-regulation of the teachers, emotional adjustment factors had negative effects on the turnover intention. It is significant in that the results of the study provided practical data necessary for enhancing the empowerment of teachers and finding ways to minimize unnecessary turnover based on self-regulation for more effective child care.

서울시의 대기오염에서 미세먼지의 추세동향 연구

박혜련 덕성여자대학교 대학원 2004 덕성여자대학교 대학원 논문집 Vol.6 No.-

PM10 has attracted an increasing amount of interest in recent years. This study aimed to illustrate long term trend in PM10 excluding confounding effect. Daily PM10 data were measured in 27 places and meteorological data (maximum temperature, humidity and maximum wind speed, solar radiation) were obtained from the national institute of environmental research for the period from January, 1996 to December 2000. To estimate the trend in a set of observed data, set up the model. The model included regression spline smooth function on the time and meteorological factors to capture the seasonal time trend and any possible nonlinear relationship. The result was estimated to decrease slightly after adjusting for meteorological factors and seasonal time trend.

식품의 영양표시제도 장착을 위한 기초조사(1) : 소비자 인식 연구 With a Reference to the Consumer Awareness

박혜련,민영희 한국식생활문화학회 1995 한국식생활문화학회지 Vol.10 No.3

Consumer awareness of current food labeling system and new nutrition labeling system which the government considers to adopt widely was assessed, from May to June in 1994, for 423 adults living in Seoul. Being highly conscious of food safety, they thought the current food label did not provide sufficient information. Dissatisfaction with the current system was shown higher in the female, young, or unmarried strata. The need for nutrition labeling system was widely recognized by 82% of total respondents regardless of sex, level of education, monthly income, and marital status. Although some expressed worries about proper management of the system, most of the respondents answered that the system would benefit them after all. In this connection, 59% of the respondents showed willingness to accept a price increase to be entailed by nutrition labeling. Nutrition informations that, they thought, should be covered were: calorie>minerals>cholesterol>protein>vitamins>fat>sodium. Additional labeling informations they called for were nutrient contents>RDA percentage>specific statement on reinforced or eliminated nutrients.
