시장 출시 전 신상품 수요 예측에 관한 연구 : 위성DMB 사례를 중심으로
박윤서,변상규,Park, Yoon-Seo,Byun, Sang-Kyu 한국경영과학회 2006 經營 科學 Vol.23 No.3
This study is to propose a sales forecasting framework for new products in the prelaunch phase where no saies data are available. For the purpose we first develop an extended Bass model with the dynamic market potential and then propose an estimation method based on the market survey and scenario methodology. The proposed parameter estimation method is different from previous studies in that most of them have only Proposed the management judgments or analogies. We also apply the proposed model to satellite DMB market in Korea to verify the model.

For the last decades, service quality has been studied as one of the most important tools for a service company to compete with the other companies. Based on these past researches, it has been agreed that the service quality is a basic and powerful tool to create the competitive advantage. Due to similar reason, many service marketing practitioners have been also focused on the service quality to retain the existing consumers and collect the new consumers. However, service quality is subjectively perceived by individual consumers. Consumer evaluation of service quality can be different from each other. Especially consumers with one life-style may evaluate the service quality differently from the consumers with the other life-styles. Therefore we need to know whether there are differences in service quality perception on the categories of life-style. Life-style refers to a distinctive mode of living in its aggregate and broadest sense. It embodies the patterns that were developed and emerged from the dynamics of living in a society. Since the concept of life-style and its relationship to marketing was introduced in 1963 by William Lazer, methods of measuring the life-style and their application have been developed. Life-style has been usually used to segment the marketplace because it offers marketers a unique and important view of the market. When Life-style is combined with clustering methods, life-style segmentation can generate identifiable whole persons rather than isolated fragment. Life-style segmentation begins with people instead of products and classifies them into different life-style types, each characterized by a unique style of living based on a wide range of activities, interests, and opinions(Plummer, 1974). In this study we applies the life-style segmentation based on the AIO(Activities, Interests, and Opinions) to the consumers of the large discount stores. In Korea, the large discount store market has entered into maturity stage so that the market differentiation strategy is becoming a more critical issue to the marketing practitioners. One of the most important tools to differentiate from the competitors in large discount store market is continuously to provide service of better quality than competitors. This study tries to find answers about the following questions: 1) How can we categorize the consumer life-styles in the large discount store? 2) What are the characteristics of the categorized groups? 3) Are there any differences in service quality perception among the consumers with different life-styles 4) Are there any differences in consumer behavior among them in the large discount store? For the purpose, we collected survey data from consumers and analyzed the data with the SPSS package where we had $X^2$-test, factor analysis, ANOVA, MANOVA, and cluster analysis. The survey was made during one month in the April of 2008. Among the collected 306 copies of questionnaires, 281 copies were chosen as the effective samples for empirical analysis except 25 copies with wrong responses. To identify the life-style patterns, we used the measures employed by Kim and Kwon(1999), where 44 items on a seven-point scale were used to measure factors of the life-style patterns. The Principal Component Method was used for factor extraction, and the VARIMAX orthogonal factor rotation was employed. The 7 items showing low factor loading were eliminated. The results of the factor analysis suggested that nine factors of the life-style patterns were identified as follows: 1) the equality-of-sexes and pursuit-of-independence tendency 2) self-management tendency 3) sociable tendency 4) self-display tendency 5) degree of a dilettante life 6) pursuit-of-information tendency 7) bargain hunter tendency 8) TV preference tendency 9) pursuit-of-leisure tendency. Next, after the K-means cluster analysis was performed with nine factors of the life-style patterns, the life-styles of the respondents were classified into four g

하이브리드 IT신제품의 범주화에 따른 보완재 번들링의 효과성에 관한 연구
박윤서(Yoon seo Park),김용식(Yong sik Kim) 한국IT서비스학회 2014 한국IT서비스학회지 Vol.13 No.4
Categorization means the process labeling or identifying an object based on what people already know or its similarity for people to be easily perceptible in external environment. If it is categorized, it is schematically conjectured from typical characteristic of the category. In this sense, the categorization of new products has an important effect upon the market performance. Nevertheless, the categorization of innovative new products is not easy and occasionally very ambiguous. In this study, we discuss how to strengthen the categorization strategy of new hybrid IT products through complementary bundling. The model of this study is based on Technology Acceptance Model (TAM) with resistance variable and verifies the statistical significance by undertaking a survey on consumers' awareness. In addition, we review the moderating effects of prior knowledge in the adoption process of complementary bundling. Through this analysis, we find out the structural relationship among the factors affecting adoption of complementary bundling. Also, it show that the influence of prior knowledge in respect of the adoption process is greater than others in case that there exists significant heterogeneity among strategic categories and complements. In conclusion, these findings suggest the following managerial implication. The categorization strategy of new hybrid IT product can be enhanced by complementary bundling, but the suitability among strategic category and complements should be evaluated exhaustively.

본 논문은 지상파DMB와 위성DMB 두 서비스 간의 비교 분석을 통해 소비자 수용도에 있어서 어떠한 차이가 있는지 알아보고자 하였다. 이를 위해 소비자 설문조사를 실시하였고, 소비자들을 지상파DMB와 위성DMB 선호유형에 따라 비선호집단, 지상파DMB선호집단, 위성DMB선호집단, 듀얼형 선호집단 등 네 가지 유형으로 분류하여 이들 세분집단별로 소비자 특성에 있어서 어떠한 차이가 있는지 분석하였다. 분석결과 첫째, 집단별 비율에 있어서 비선호집단(60.4%)이 가장 높게 나타났으며, 그 다음으로는 듀얼형 선호집단(18.5%)이었는데 이러한 사실은 양쪽 서비스 모두를 함께 이용할 수 있는 듀얼형 서비스의 필요성을 제기하고 있다. 둘째, 인구통계학적 특성에 있어서는 특히 소득이 높을수록 위성DMB를, 중산충일수록 지상파DMB를 선호하고, 저소득층은 DMB에 대한 관심이 낮은 것으로 분석되었다 셋째, DMB 선호유형별 기존 통신방송 이용에 있어서의 차이를 알아본 결과 케이블TV 이용자는 지상파DMB를 선호하고 위성TV 이용자는 위성DMB를 상대적으로 더 선호하는 것으로 나타났다. 넷째, DMB 선호유형별 라이프스타일 특성을 알아본 결과 대체로 위성DMB는 혁신형 고객이 선호하고 지상파DMB는 실속형 고객이 선호하는 것으로 나타났다. 마지막으로, DMB 선호유형별로 DMB에 대한 태도를 알아본 결과 대체로 위성DMB 선호자들이 DMB에 대해 가장 긍정적인 태도를 갖고 있는 것으로 분석되었다. This study is to analyze the differences of consumer preferences between the terrestrial DMB and satellite DMB in various segment groups by using survey data. We categorized the consumers by the DMB preference patterns into four groups, i e , non users group, terrestrial only users group, satellite only users group, dual users group. And then we analyzed the differences among these four segment groups in demographic characteristics, behavior patterns on telecommunication and broadcasting services, life-style, attitudes to DMB services.

보험서비스 산업에서 관계혜택과 지각된 위험이 관계마케팅 성과에 미치는 영향에 관한 연구
박윤서(Park, Yoon Seo),이승인(Lee, Seung In),장우성(Jang, Woo Sung) 한국서비스경영학회 2011 서비스경영학회지 Vol.12 No.5
This study first aims to gain a deep understanding of the relational benefit and perceived risk as antecedent factors which influence the trust, customer satisfaction, churn intention, and negative word of mouth intention of the insurance services. Above all, this study tries to present a framework integrating the relational benefit and perceived risk. Second, it aims to grasp the moderating effect in the research model by applying to two insurance services(life and automobile insurance) with different service subscription duration. With a consumer survey data, we tested the hypothesized research model. The research results show that most of paths hypothesized in the research model were found significant. Also the insurance product types(life and automobile insurance) with different service subscription duration are shown to have a specific moderator effect. Based on these results, managerial implications for the effective relationship marketing strategy in the insurance industry are discussed. In addition, some limitations of this study and future research directions are suggested.
