Willingness to provide personal information: Perspective of privacy calculus in IoT services
Kim, Dongyeon,Park, Kyuhong,Park, Yongjin,Ahn, Jae-Hyeon Elsevier 2019 Computers in Human Behavior Vol.92 No.-
<P><B>Abstract</B></P> <P>Recent developments in the Internet of Things (IoT) technology provide an unprecedented opportunity for personalized services. To take advantage of this great potential, consumers are willing to provide their personal information at the risk of privacy breach. This paper examines factors affecting the willingness to provide privacy information based on the privacy calculus theory in several IoT services; healthcare, smart home and smart transportation. The proposed model is estimated using survey data collected from 154 people who know the concept of IoT. The results indicate that people do not pay much attention to perceived privacy risk when providing privacy information for a better personalized service. However, in healthcare service, where perceived privacy risk is high, people are not willing to provide their personal information despite the lower expected value from incomplete personalization. Analysis of privacy behavior in the context of IoT services provides implications for and insight into the tradeoff decision between perceived privacy risk and willingness to provide personal information.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Perceived benefit has an effect on the willingness to provide privacy information. </LI> <LI> Some network externality factors have a significant effect on perceived benefit. </LI> <LI> Perceived privacy risk does not matter when providing privacy information. </LI> <LI> Despite the lower expected value from non-personalization, risk matters in healthcare. </LI> </UL> </P>
Fault Diagnosis of Ball Bearings within Rotational Machines Using the Infrared Thermography Method
Dongyeon Kim,Hanbit Yun,Sungmo Yang,Wontae Kim,Dongpyo Hong 한국비파괴검사학회 2010 한국비파괴검사학회지 Vol.30 No.6
In this paper, the novel approach for the fault diagnosis of the bearing equipped with rotational mechanical facilities was studied. As research works, by applying the ball bearing used extensively in many industrial fields, experiments were conducted in order to propose the new prognostic method about the condition monitoring for the rotational bodies based on the condition analysis of infrared thermography. Also, by using the vibration spectrum analysis, the real time monitoring was performed. As results, it was confirmed that infrared thermography method could be adapted into monitor and diagnose the fault for bearing by evaluating quantitatively and qualitatively the temperature characteristics according to the condition of the ball bearing.
