Quality function deployment is an interdisciplinary team process of listening to customers to learn exactly what they want, and then using a logical system to determine how best to fulfill those needs with available resources. It is examined how to extend quality function deployment in this paper. The Pugh concept selection method, ACE(Attribute Categorization and Evaluation) Matrix, and an inventive problem solving method called TRIZ are discussed in relation with quality function deployment.

The research purposes are (1) to identify male market segmentation based on fashion involvement, (2) to compare purchase intention of clothing items and store attribute evaluation at two different retail formats, department store and internet shopping mall, and (3) to compare the influence of store attributes on intention to purchase fashion products at two retail formats among segments. The data are collected from 275 male consumers through internet research institute. The major results of this study are as follows. First, the dimensions of fashion involvement are identified into external involvement and internal involvement. Male respondents present high mean scores on external involvement items, emphasizing social roles of clothing. Two involvement factors generate three market segments: high involvement group(32.4%), external involvement group(44%), and low involvement group(23.6%). Second, high involvement group shows higher mean scores on purchase intention of seven clothing items than low involvement group. Third, department store attributes are identified into four factors, product assortment, quality per price, service, and symbolic image, while internet shopping mall includes assortment & convenience, quality per price, and symbolic image. High involvement group again presents higher mean scores on each retail attribute factor than low involvement group. Finally, quality per price is the most significant variable to explain the purchase intention at department store among three market segment, whereas assortment & convenience and quality per price are important predictors to increase purchase intention at internet shopping mall. However, relative importance of each attribute variable is different among three involvement groups.

The purpose of this study was to standardize ingredients used by school foodservices. This study analyzed the current notation of ingredients in used by used in school foodservices through the NEIS system employed by school foodservices of elementary schools through high schools in South Korea. Specifically, this study suggests systemized standardization of ingredient classification and quality attributes of at school foodservices by applying a case study analysis. The findings from the case analysis of the Electronic Procurement System operator are as follows. Classifications for ingredients of the NEIS system used by school food services consisted of included food group, food name, detailed food name, and description. Classification was not clearly divided between the classification scheme and the attribute system. Therefore, food group, food name, and product information of each food should be categorized as the classification scheme, whereas the detailed food name (excluding product information) and description should be standardized as the attribute system, which is composed of required attributes, recommended attributes, and other attributes. This study suggests that system standardization should be carried out in the field of school foodservices, as advancements between distributors and school food service providers could affect food ingredient quality. Thus, standardization can influence purchase and distribution in many ways.

Often in a production process, the quality of items is serially dependent. We assume that the quality of items is an attribute which can be classified as good or bad with a Markovian dependence structure. In order to determine sampling inspection plan characteristics such as total inspection cost and average outgoing quality, we design an economic model and illustrate an efficient procedure for design of best inspection plan using graphs based on numerical calculations.

The purpose of this study was 1) to identify the constructing factors of jeans brand image 2) to analyze the domestic jeans market using perceptual maps of three benefit segments based on stdy(I). The questionnaire consisted of brand preference, attribute of brand image and wearer image was selected from the previous studies or developed for this study. The subjects were 350 male and female university students who have purchased at least one of the nine jeans wear brand selected for the study. For statistical analysis, reliability test, factor analysis, MANOVA, and multiple regression were used. The results of this study were as follows: 1. Symbolism, quality, and economy were found out as constricting factors of brand image in the attribute dimensions, while innovative and active image were found out in the wearer image dimensions. 2. 9 Perceptual maps of attribute dimensions and 3 perceptual maps of wearer image dimensions were constructed and each ideal vector was drawn.

The importance and satisfaction with the purchasing characteristics and choice attribute of home meal replacement (HMR) products for consumers aged between 20 and 40, or over 50. In addition to identify the factors that must be first considered in the development of HMR products importance-performance analysis. 791 consumers aged between 20 and 40, or over 50, living in Seoul have experience in purchasing HMR participated in the survey. The survey consisted of four sections: The purchasing characteristics of HMR, the importance and satisfaction with HMR choice attribute, and general questions. T-tests and IPA were conducted to compare the groups of consumers aged between 20 and 40, or over 50. The factor analysis show the following results: 0.899 for "convenience", 0.094 for "hygiene", 0.871 for "quality", 0.834 for "taste", and 0.822 for "price". The average score of the importance of the choice attribute when purchasing HMR products 3.50. For consumers aged between 20 and 40, the score 3.49. For consumers over 50, the score 3.52. There is a significant difference "hygiene (p<0.001)", "quality (p<0.05)", and "price (p<0.05)". For consumers aged between 20 and 40, the score 3.72. For consumers over 50, the score was 3.78. There a significant difference only in "hygiene (p<0.05)". The results of the IPA demonstrate that the categories that belong to "Focus here" are "new HMR products" and "diverse HMR products" for all consumers aged between 20 and 40 and over 50. Hence, food companies should endeavor to develop new and diverse HMR products first.

자연어로 작성되는 소프트웨어 요구사항은 이해관계자가 바라보는 관점에 따라 의미가 달라질 수 있다. 품질 속성 기반으로 아키텍처 설계시에 품질 속성별로 적합한 설계 전술(Tactic)을 선택해야 효율적인 설계가 가능해 품질 속성 요구사항의 정확한 분류가 필요하다. 이에 따라 고비용 작업인 요구사항 분류에 관한 자연어처리 모델이 많이 연구되고 있지만, 품질 속성 데이터셋(dataset)의 불균형을 처리해 분류 성능을 개선하는 주제는 많이 다루고 있지 않다. 본 연구에서는 먼저 실험을 통해 분류 모델이 한국어 요구사항 데이터셋을 자동으로 분류할 수 있음을 보인다. 이 결과를 바탕으로 EDA(Easy Data Augmentation) 기법을 통한 데이터 증강과 언더샘플링(undersampling) 전략으로 품질 속성 데이터셋의 불균형을 개선할 수 있음을 설명하고 요구사항의 카테고리 분류에 효과가 있음을 보인다. 실험 결과 F1 점수(F1-Score) 기준으로 최대 5.24%p 향상되어 불균형 데이터 처리 기법이 분류 모델의 한국어 요구사항 분류에 도움이 됨을 확인할 수 있다. 또한, EDA의 세부 실험을 통해 분류 성능 개선에 도움이 되는 데이터 증강 연산에 관해 설명한다.

Price acceptability has become an important issue in the current fashion market. This study explored diverse factors that affect price acceptability (level of acceptable price and range of acceptable price). Stimuli photos of fashion products (i.e., bag, shoes, and jacket) were developed and used for online experiments with 3,000 female consumers. Important results included factors that affected the price acceptability of fashion products were price-quality relation, price concern, and product attribute perception. The results showed that female consumers depended more on price-quality relations, more positively perceived product attributes, and were less sensitive to price; in addition, they tended to have a higher level of acceptable price as well as a wider range of acceptable price for fashion products. These results were consistent across all experiments with different fashion items (i.e., bag, shoes, and jacket). Based on the results, factors that influence the price acceptability were revealed. Marketing practitioners need to more actively consider implying advertising strategies that emphasize the advancement of product attributes such as quality for highpriced products.
