As maintaining customer long term relationship is critical factor for improving to firm value as well as customer lifetime value, the academicians and practitioners have paid attention to customer defection. It is said that service failures are key factors to customer defection or customer switching(Keaveney 1995 etc.). This study examines that the effect on customer defection of service failures is differential according to the various customer-firms relationship characteristics. We consider relationship duration, usage level, decision making influence, industry knowledge and switching cost as customer-firm relationship characteristics based on marketing literature. Predictions are developed and tested using Internet service provider(ISP) user survey data(n=212). Results show that the customer-firms relationship characteristics/above variables) play a moderating roles in the service failures and customer defection links.

Travel voucher for low-income or social disadvantaged groups forms a part of social policies in Korea. The policy can not only provide an opportunity of travel experiences for the socially weak, but also enhance their family capital and social capital. Thus, the travel voucher policy can be beneficial for the participants and their society. However, little research evidence of its evaluation and challenges/benefits exists. In practice, one of the biggest problems is an attrition of travel voucher winners which is to decrease a cost-effect of the travel voucher policy and to increase unnecessary waste of both the federal and human resources. Thus more research is needed to answer the questions why some of winners abandon to go to travel by the voucher, and who is the seceder? In this context, the study empirically examines the attrition propensity for the winners of 2011 Seoul travel voucher from 1,632 respondents and second data from Korea Tourism Organization. This research found that total education years of travel voucher winners have a significant effect on using their voucher. Implications and alternative policies for government policy makers and administrators are discussed by the analyzed results.

This paper proposes a lane departure detection algorithm using a single camera equipped in front of a vehicle. The proposed algorithm generates a partial top-view image for a small ROI (region of interest) designated on the top-view space form the image acquired by the camera, detects lanes on the small partial top-view image, and makes a decision on the lane departure by checking overlap between the pre-assigned virtual vehicle and the detected lanes. The proposed algorithm also includes the removal of lines occurred by road symbols (noises) disturbing the lane departure detection between lanes and the prediction of lost lanes using lane information of previous fames. In lane departure detection test using real road videos, the proposed algorithm makes the right decision of 99.0% in lane keeping conditions and 94.7% in lane departure conditions.

This study is performed to identify attribution styles of the North Korean Defectors more accurately. For this purpose, cartoon-form method designed to measure attributions is used and total 129 subjects including comparison group of South Koreans are participated in this research. Interestingly, the result showed that two groups had similar and different attribution styles at the same time. That is, there is a common aspect in using internal attributions more in general, but there is also a different aspect in that South Koreans used internal attribution much more. These tendencies emerged similarly at the controllable and uncontrollable attribution dimension. However, the results demonstrated that South Koreans mainly used stable attribution and the North Korean Defectors used unstable attribution at the stable and unstable attribution dimension. And, the attributional styles of both koreans appeared consistently in a variety of scenarios. Finally, there was the stronger relationship between North Korean defectors' life satisfaction and attributional styles.

This study examined the influential relationship between self-differentiation, interpersonal relationships, and social support of adolescent North Korean defectors as well as the mediating effects of social support in the relationship between self-differentiation and interpersonal relationships. For this study, the participants were selected among student North Korean defectors aged between 9 and 24 years. With these participants, a survey was conducted from November 4 to December 14, 2019. Two hundred eighteen questionnaires were used in the analyses, which were conducted with SPSS 23.0 and AMOS 23.0. The analyses yielded the following findings. The self-differentiation of the adolescent North Korean defectors had a positive impact on interpersonal relationships. The self-differentiation of adolescent North Korean defectors had a positive impact on social support, and the social support of adolescent North Korean defectors had a positive impact on interpersonal relationships. In the relationship between self-differentiation of adolescent North Korean defectors and their interpersonal relationship, social support had a mediating effect. This study showed that by improving the level of social support and self-differentiation of adolescent North Korean defectors, it would be possible to improve their interpersonal relationship issues.

Aids to Navigation (AtoN) are marine traffic facilities to improve the safety and efficiency of shipping. "New Dangers" should be appropriately marked using lateral, cardinal or isolated danger marks or by using an Emergency Wreck Marking Buoy. However, Emergency Wreck Marking Buoys are difficult to implement in terms of speed and accuracy of installation. In the case of sinking accidents, it is often difficult to immediately install an Emergency Wreck Marking Buoy because of weather conditions, the marine environment or accident positioning. This study concerns Auto-Releasing Emergency Wreck Marking Buoys, which should be installed in all vessel for safe marine navigation and efficient maritime transport with reference to the Maritime Buoyage System (MBS). Auto-Releasing Emergency Wreck Marking Buoys include an auto-release unit, auto reel chain and auto lighting lantern. These buoys can be automatically released from the deck of a vessel and will float in the water for quick installation at the scene of an accident, even in the case of sinking accidents. Auto-Releasing New Mark Buoys are expected to reduce to installation process, prevent secondary accidents by the risk of navigation and be search and rescue rapidly.
