In recent, T-commerce is widely dispersed as alternative type of commerce. It is forecasted that t-commerce system is used more than e-commerce system. Therefore more and more t-commerce-related industries are also recognizing that t-commerce is a critical business model. It is needed to understand the concept of t-commerce and develop the t-commerce marketing strategy. CEO analyses consumer's behaviors according to the data about buyers and applies the advantage of t-commerce to the communication with customers. This t-commerce system plays an important role in maximizing customer satisfaction and affecting their intention to reuse it. Therefore this paper attempts to identify T-commerce critical success factors and divide between use-intention group and unuse-intention group by taking out a discriminant function by the discriminant analysis. This lays a foundation in developing T-commerce strategy. According to the discriminant function extracted, convenience factor, amusement factor, system quality factor, product perception factor are significant in the sequence of influential degree. However, usefulness factor and speedy connection factor are not significant. In result, the target hitting rate is 77.9% in the first unuse-intention group and it is 95.2% in the second use-intention group. The total discriminant target hitting rate is computed to higher value, 86.55%. The statistic package, SPSS 12.0, is used to survey and analyse data and test the hypothesis. The validity and reliability of variables are verified by both reliability analysis and factor analysis. The discriminant analysis is used to tell the difference between use-intention group and unuse-intention group.

As the consuming pattern is changing with the expansion of Internet use and the development of communication technology, Internet shopping market is getting bigger and bigger. By product group, clothing and fashion related products occupy the biggest share. Accordingly, in this study it was tried to identify the effects of Internet utilization capability that enables consumers to search for the information that they need in this information flood, variety pursuit trend and product review accommodation status on shopping value, and to analyze the effects of the shopping value on the purchase behavior in online shopping malls. When factor analysis is nude on Internet use level, it was found that Factor 1 was 'Flow Experience,' Factor 2 'Internet Use Capability,' and Factor 3 'Internet Challenge Desire.' When factor analysis is made on Diversity Pursuit Propensity, it was found that Factor 1 was 'Site Diversity Pursuit Propensity,' Factor 2 'Brand Diversity Pursuit Propensity,' and Factor 3 'Brand Value Pursuit Propensity.' When factor analysis is nude on Product Review Accommodation Propensity, it was found that Factor 1 was 'Product Information Provision Propensity,' and Factor 2 'Product Information Receiving Propensity.' Except Internet Use Capability and Product Information Provision Propensity, all other factors showed high correlation. The factor influencing the entertainment value most was Internet challenge desire, while that influencing the practical value most was flow experience. When the effects of the entertainment value and the practical value on product purchase were analyzed, it was found that both of entertainment value and the practical value influenced product purchase and the practical value influenced the product purchase more than the entertainment value.

본 연구는 행동경제학(Behavioral Economics) 관점을 적용하여 이용자들이 OTT 플랫폼을 지속적으로 이용함에 있어서 영향을 미치는 요인을 탐색하였다. OTT 이용자들이 실제 콘텐츠를 시청하고 플랫폼에서 제공하는 기능을 직접 경험한 후 만족을 느끼는 합리적 요인 외에도 '현상유지 편향(status quo bias)'에 의한 습관적 요인과 지인, 비용 등 상황에 따른 감정적, 심리적 요인도 영향을 미칠 것으로 판단했다. OTT 이용자들을 대상으로 한 심층 인터뷰와 선행 연구들을 통해 도출한 4가지 요인(콘텐츠 만족요인, 기능적 만족요인, 관성적 요인, 상황적 요인)에 대한 세부 문항을 구성하고, 국내 구독자 Top3 OTT 플랫폼(넷플릭스, 웨이브, 티빙)의 이용경험이 있는 전국의 20-40대 성인남녀 523명을 대상으로 온라인 설문조사를 실시하였다. 분석결과, '콘텐츠 만족요인'과 '기능적 만족요인', '관성적 요인'이 OTT 지속적 이용에 유의미한 영향을 미치는 것으로 나타났으며, 이 중 '관성적 요인'은 국내 OTT 이용자들에게는 영향을 미치지 않았다. 본 연구는 OTT 서비스 이용자들을 완전한 합리성을 갖춘 존재로 전제했던 기존의 선행연구들과는 다르게 제한적 합리성을 함께 고려하여 OTT 지속적 이용 행위에 대한 설명의 범위를 넓혔다는 의의를 가진다.

본 연구에서는 시뮬레이션 방법을 사용해서 다양한 조건에서 주성분분석이 얼마나 잘 요인 구조를 복원할 수 있는지를 공통요인분석과 비교하여 체계적으로 평가하였다. 이 연구에서 요인 대 변수 비율, 공통성, 그리고 표본크기를 실험변수로 설정하였다. 주성분분석은 표본의 크기가 200개 이하인 경우 공통적으로 공통요인분석에 비해 더 우수한 요인구조의 복원력을 보여주었다. 특히, 요인 당 변수 수가 적은 경우, 주성분분석은 50개의 표본에서도 만족할 만한 수준의 요인복원능력을 보여주었다. 이와 더불어 공통성 수준 또한 낮은 경우 필요한 표본수는 100개로 늘어난다. 본 연구결과는 요인추출방법으로서 주성분분석의 선택의 근거를 제시하고 타당한 사용에 관한 가이드라인을 제시해 준다.

We consider the estimation of failure rate and acceleration factor under type-I censoring without using acceleration model when testing is conducted in only one highly accelerated condition. Failure times of an item are assumed to be exponentially distributed. It is also assumed that the uncertainty about the acceleration factor, the failure time contraction ratio between accelerated condition and use condition, can be modeled by the uniform or gamma prior distribution of appropriate parameters. We respectively use Bayes and maximum likelihood approaches to estimate acceleration factor and failure rate in the use condition. An example is given to show how the method can be applied.

본 연구는 이용계수를 적용하여 국내 공공도서관의 소설장서를 평가하고 장서개발기능을 제고시키기 위한 다양한 방안을 제시하였다. 그 결과, 한국문학은 언어별 문학에서의 장서구성 및 이용대출 비중이 각각 62.6%와 54.3%로 가장 높았음에도 불구하고 이용계수(0.87)는 기준값(1.00)보다 낮았다. 또한 한국현대소설은 한국소설의 세목별 장서구성 및 이용대출에서의 비중이 각각 65.60%와 51.36%로 가장 높음에도 이용계수(0.78)는 기준값보다 낮았고 연도별 이용계수도 최근 연도에 근접할수록 감소하고 있다. 그 이유는 장서개발이 부실하기 때문이다. 그러므로 공공도서관은 장서개발정책 및 소설장서개발지침의 수립, 소설자료선정위원회의 구성, 소설자료개발 전담사서제 도입, 소설자료 선정도구의 개발과 활용, 소설장서의 주기적 평가와 같은 방안의 도입을 적극적으로 검토할 필요가 있다.
