Purpose: In this paper, the minimal repair-replacement warranty policy is used to carry out a warranty cost analysis with warranty servicing times and failure times that are statistically correlated to bivariate distributions. Methods: Based on the developed approach by Park and Pham (2012a), we investigate the property of the Freund's bivariate exponential distribution and obtain the number of warranty services using the field data to conduct the warranty cost analysis. Results: Maximum likelihood estimates are presented to estimate the parameters and the warranty model is investigated using a Freund's bivariate exponential distribution. A numerical example is discussed to deal with the applicability of the developed approach in the paper. Conclusion: A novel approach of analyzing the warranty cost is proposed for a product in which failure times and warranty servicing times are used simultaneously to investigate the eligibility of a warranty claim.

In this thesis, we present process that remove mistake of data before statistical analysis. If field data which is not simple examination about validity of data, we cannot believe analyzed statistics information. As statistical analysis information is produced based on data to be input in statistical analysis process, the data to be input should be free of error. In this paper, we study the application of statistical analysis road map that can enhance application on site by organizing basic theory and approaching on initial data exploratory phase, essential step before conducting statistical analysis. Therefore, access to statistical analysis can be enhanced and reliability on result of analysis can be secured by conducting correct statistical analysis.

IT portfolio, meaning the ratio of investment with four different purposes of IT, is widely used for evaluating the adequacy of investment and its performance within firms. Despite of such a useful framework looking at investment on IT, IT portfolio in agriculture industry seems to be differentiated from other industries. In this study, we compared IT portfolios of farms: grain, field fruit and vegetable, greenhouse fruit, greenhouse vegetable, beef cattle and pig. We classified farms by their return on equity (ROE) in order to analyze the relationship between IT portfolio of each crop and performance. Then, we found patterns of IT portfolios of top-performance farms compared to all farms for each agricultural product. Lastly, peculiarities of each crop are interpreted and discussed to find out top-performance farms' IT investment patterns. From our study, it could be inferred that monotonous IT investments may not be as effective.

근거리 무선통신 (Near Field Communication: NFC) 기술을 이용한 서비스가 많이 소개되고 있다. 본 연구의 목적은 NFC 간편결제 채택의도에 영양을 미치는 요일을 찾기 위한 것이다. 이를 위해, 본 연구는 기술수용모델(Technology Acceptance Model: TAM)을 기반으로 한 연구모형을 제안하고자 한다. 인터넷 설문조사를 통해 NFC 간편결제 서비스를 사용하는 사용자 353명의 자료가 수집되었다. 분석결과 상대적 이점, 사회적 영향 및 기술 가용성이 인지된 유용성에 중요한 영향을 미친다는 것을 확인할 수 있었다. 그러나 사용 용이성에는 상대적인 이점과 사회적 영향만이 영향을 미치는 것으로 확인되었다. 인지된 사용 편의성은 인지된 유용성에 큰 영향을 미치며, 이들 모두 NFC 간편결제 채택의도에 큰 영향을 미치는 것으로 나타났다. 또한 분석결과, 개인 혁신성이 조절효과는 가지는 것으로 밝혀졌다.
