The purpose of this study is to verify relationships among attributes of ramen package design, ramen image, and chinese customer's choice of ramen. We chose, as a sample, ramen 'sour ramen', 'squid jjambbong', 'tasty ramen', 'noodle beef soup', and 'seasame ramen'. The findings and implications can be summarized as follows. first, while chinese customers chose 'sour ramen' as the most favorable ramen, followed by 'tasty ramen', 'squid jjangbbong', 'noodle beef soup', and 'seasame ramen', for ramen image they most highly evaluated 'sour ramen' followed by 'squid jjangbbong', 'tasty ramen', 'seasame ramen', and 'noodle beef soup'. Second, there is a significant difference in popularity and reliability of quality, but no significant difference in attractiveness and healthiness among most attributes of ramen package design. Third, compared to 'seasame ramen', the popularity and reliability of quality for 'sour ramen', reliability of quality for 'squid jjangbbong', reliabilty of quality, and healthiness for 'tasty ramen' had positive effect on choice, while attractiveness for 'noodle beef soup' had a negative effect on their choice.

Software reliability is one of the most basic and essential problems in software development. In order to detect the software failure phenomenon, the intensity function, which is the instantaneous failure rate in the non-homogeneous Poisson process, can have the property that it is constant, non-increasing or non-decreasing independently at the failure time. In this study, was compared the reliability performance of the software reliability model using the Landely lifetime distribution with the intensity function decreasing pattern and Erlang lifetime distribution from increasing to decreasing pattern in the software product testing process. In order to identify the software failure phenomenon, the parametric estimation was applied to the maximum likelihood estimation method. Therefore, in this paper, was compared and evaluated software reliability using software failure interval time data. As a result, the reliability of the Landely model is higher than that of the Erlang distribution model. But, in the Erlang distribution model, the higher the shape parameter, the higher the reliability. Through this study, the software design department will be able to help the software design by applying various life distribution and shape parameters, and providing software reliability attributes data and basic knowledge to software reliability model using software failure analysis.
