  • Purpose: Market basket analysis is one of the most frequently used methods in the retail industry today as a technique to discover the product association. It is empirically analyzed how these product associations differ regionally in the case of the United States. Research design, data, and methodology: Based on the purchasing data of consumer panels collected from 49 US states, the association rules for each state was extracted with the corresponding lift values indicating product association. The difference in lift values in 49 states by the association rule was compared and tested for 49 states and for 4 census regions (Northeast, Midwest, South, West). Results: The association rules of 3/4 of the same association rules show positive associations or negative associations depending on the lift values of the states. There were significant differences in the lift values for 49 states, and for 4 census regions. These significant differences in the lift values were found to be related to the distance between states and whether states belong to the same census region. Conclusions: Retail product associations shown by market basket analysis may vary depending on regional distance or regional heterogeneity. It is necessary to pay attention to these points in multi-store environment.

  • 인터넷 상거래에서, 소비자들은 기존에 제품을 구매한 다른 사용자들이 작성한 상품평에 많은 영향을 받는다. 그러나, 상품평이 점차 축적되어감에 따라, 소비자들이 방대한 상품평을 일일이 확인하는데 많은 시간과 노력이 소요되고, 또한 무성의하게 작성된 상품평들은 오히려 소비자들의 불편을 초래하기도 한다. 이에, 본 연구는 온라인 상품평의 유용성에 영향을 미치는 요인들을 분석하여, 소비자들에게 실제로 도움이 될 수 있는 상품평을 선별적으로 제공하는 예측모형을 도출하는 것을 목적으로 한다. 이를 위해, 텍스트마이닝 기법을 사용하여, 상품평에 포함되어있는 다양한 언어적, 심리적, 지각적 요소들을 추출하였으며, 이러한 요소들 중에서 상품평의 유용성에 영향을 미치는 결정요인이 무엇인지 파악하였다. 특히, 경험재인 의류군과 탐색재인 전자제품군에 대한 상품평의 특성 및 유용성 결정요인이 상이할 수 있음을 고려하여, 제품군별로 상품평의 특성을 비교하고, 각각의 결정요인을 도출하였다. 본 연구에는 아마존닷컴(Amazon.com)의 의류군 상품평 7,498건과 전자제품군 상품평 106,962건이 사용되었다. 또한, 언어분석 소프트웨어인 LIWC(Linguistic Inquiry and Word Count)를 활용하여 상품평에 포함된 특징들을 추출하였고, 이후, 데이터마이닝 소프트웨어인 RapidMiner를 사용하여, 회귀분석을 통한, 결정요인 분석을 수행하였다. 본 연구결과, 제품에 대한 리뷰어의 평가가 높고, 상품평에 포함된 전체 단어 수가 많으며, 상품평의 내용에 지각적 과정이 많이 포함되어 있는 반면, 부정적 감정은 적게 포함된 상품평들이 두 제품 모두에서 유용하다고 인식되는 것을 알 수 있었다. 그 외, 의류군의 경우, 비교급 표현이 많고, 전문성 지수는 낮으며, 한 문장에 포함된 단어 수가 적은 간결한 상품평이 유용하다고 인식되고 있었으며, 전자제품의 경우, 전문성 지수가 높고, 분석적이며, 진솔한 표현이 많고, 인지적 과정과 긍정적 감정(PosEmo)이 많이 포함된 상품평이 유용하게 인식되고 있었다. 이러한 연구결과는 향후, 소비자들이 효과적으로 유용한 상품평들을 확인하는데 도움이 될 것으로 기대된다.

  • Precipitation was formed during the preparation of decoction from a mixture of Scutellariae Radix and Coptidis Rhizoma or Phellodendri Cortex according to the prescription of Hwang-ryean-hae-dog-tang. Baicalin and berberine were identified in coprecipitated product and these components were the active ingredients of two herbal medicine. The coprecipitated product was very slightly soluble in water and sparingly soluble in ethanol. The stoichiometric ratio of baicalin and berberine was found to be 1:1. The lipid-water partition coefficients of coprecipitated product were increased more than baicalin and berberine in chloroform, but were decreased in other organic solvents. The content of baicalin and berberine in coprecipitated product, determined by HPLC, were 23.08% and 26.75%, but the content of active ingredients in supernatant were 0.66% and 0.26%, respectively. The dissolution profile of baicalin of coprecipitated product was increased more than extract of Scutellariae Radix in artificial gastric juice, but was decreased in artificial intestinal juice. The dissolution rate of berberine of coprecipitated product was lower than extract of Coptidis Rhizoma in artificial gastric juice and intestinal juice commonly.

  • 소프트웨어 제품의 품질을 높이는데는 소프트웨어 개발프로세스 중심과 제품 중심의 2가지 접근방법이 있다 CMM, ISO 9000 패밀리나 ISO/IEC 12207, SPICE 등이 프로세스의 인증을 통해서 소프트웨어 품질을 향상시키려는 시도라고 할 수 있다. 그렇지만 ‘좋은’ 프로세스만으로는 ‘좋은’ 제품의 품질을 보장하기가 어렵다. 최근 독립적인 제3자에 의한 소프트웨어 제품의 품질을 평가하기 위한 필요가 점점 증가하고 있다. 본 연구에서는 소프트웨어 제품의 품질을 평가하는데 SQC 기법을 응용하여 평가프로세스의 효율을 기하고 평가결과의 객관성을 확보하는 방안을 다룬다. 랜덤추출법에 의한 테스트 케이스를 선정하는 방법을 소개하고 소프트웨어 제품의 품질에 대한 적합성 기준을 선정하는 방안을 제시한다.

  • A new product development is critical to the growth and success of most business firms. Increasingly, the new product development is recognized as an essential component of the corporate plan. But, relatively few research investigations have focused on the elements of a new product development strategy and its performance results. This study aims to identify the patterns of new product development strategy which business firms adopt, and its performance results. To identify these patterns and results, 268 firms in four industries known to be active in new product development were selected as a matter of convenience, and surveyed by the questionnaire and interviews. The questionnaire is composed of 67 strategy variables, 8 performance variables, and other variables. To analyze the data from samples, various statistical methods such as factor analysis, Pearson correlation analysis, sluster analysis, and one-way ANOVA were employed. This analysis brought forth the following major findings: First, three new product development strategy patterns were identified. Each strategy pattern was proved to be different from the others in terms of group of strategy elements that were adopted. Second, the new product development strategy was closely linked to its performance. Third, the difference of performance results among strategy groups in each industries was rather significant, however, the performance difference among industries in each strategy group was less significant.

  • The information sharing is essential to make collaboration by participants in the collaboration environment. The sharing of the information is necessary to reduce time-to-market of new Product. In this paper, V2-model is proposed far supporting the sharing of the information on product development. V2-model supports collaborative product development in design and supply chain. Through viewpoints, V2-model supports 1) two-level structure that consist of private level and public level ,2) level-up process and 3) product development process. The public level information supports to share the product information on collaborative supply chain and design. The viewpoints in V2-model are divided into public viewpoints that point to the public level information and private viewpoints that point to the private level information. Private viewpoints are transformed into public viewpoints. The extended Topic Map has B-Topic, S-Topic and View for representing V2-model in this paper. The level-up process of V2-model is implemented through the merging of S-Topics. V2-model is implemented with washing machine model using extended Topic Maps. In this model, the public viewpoints and private viewpoints are represented and the level-up process, which transforms private viewpoints into public viewpoints, is implemented.
