Previous studies on the success factors of big data implementation have called for future research and further examination of the top management leadership's impact. This research proposes and empirically tests three hypotheses, including how top management leadership can directly affect big data investment, how it can mediate the causal relationship between big data investment and idea usefulness, and how it can mediate the relationship between idea usefulness and business utilization. Based on the data collected from 108 big data users in Korean companies, we determined that all three hypotheses are statistically significant. By shedding light on top management leadership and its characteristics, we can provide better suggestions on what needs to be done to ensure the success of big data.

본 연구에서는 아두이노를 기반으로 하는 스마트 조도 반응 시스템을 구현한다. 조도센서를 활용해 주변 광량을 실시간으로 감지하고, 이를 기반으로 모터를 제어하여 편광 필터의 위치를 조절한다. 이 시스템은 강한 햇빛 조건에서 차선 인식의 명확성을 높이는 데 기여할 수 있을 것으로 생각된다. 현업에서 해당 기술을 사용하기 위해서는 추가적인 작업이 요구될 수 있지만, 본 연구는 새로운 아이디어의 탐색과 하드웨어의 구체적인 구현 방안을 제시함으로써 이후의 연구 방향성을 제안한다.

In this paper, we investigate how the online voting system can be a trust-based system from a technical perspective. Under four principles of voting, we finely evaluate the existing belief that offline voting is safer and more reliable than online voting based on procedural processes, technical principles. Many studies have suggested the ideas for implementing online voting system, but they have not attempted to strictly examine the technologies of online voting system from the perspective of voting requirements, and usually verification has been insufficient in terms of practical acceptance. Therefore, this study aims to analyze how the technologies are utilized to meet the demanding requirements of voting based on the technologies proven in the field. In addition to general data encryption, online voting requires more technologies for preventing data manipulation and verifying voting results. Moreover, high degree of confidentiality is required because voting data should not be exposed not only to outsiders but also to managers or the system itself. To this end, the security techniques such as Blind Signature, Bit Delegation and Key Division are used. In the case of blockchain-based voting, Mixnet and Zero-Knowledge Proof are required to ensure anonymity. In this study, the current status of the online voting system is analyzed based on the field system that actually serves. This study will enhance our understanding on online voting security technologies and contribute to build a more trust-based voting mechanism.
