본 연구에서는 안전하면서도 쉽게 사용할 수 있는 블록체인 기반의 중고 책 거래 플랫폼을 개발하였다. 이 플랫폼은 블록체인의 특성을 이용해 거래 제품 및 거래내역을 공유원장에 기록하여 거래내역을 투명하게 공개하며 누구나 열람 가능하다. 이는 데이터의 무결성과 투명성을 보장하며 신뢰성 있는 거래 환경을 제공한다. 이를 사용할 경우, 기존 중고거래 시스템에서 발생 가능한 데이터의 위조, 변조의 문제점과 불확실한 신뢰 문제가 해결되어 중고거래 사기사건을 예방할 수 있다.

The purpose of this study is to examine of transparency and Corporate Social Responsibility(CSR) on financial performance and firm value. The empirical results are as follows: First, we finds that ROA showed significant effect of all transparency measures exception QAS measure and Tobin's Q showed significant effect of CITSA, SCTSA, SETR and SATSA. Second, 'Total-ROA' and 'ROA' models showed significant positive effects of lnCSR(TranD${\times}$lnCSR) and ROA, also 'Total-Tobin's Q' and 'Tobin's Q' model had same results. Consequently, this study results had that The firms with higher transparency and higher CSR exhibit better financial performance and firm value.

In this paper, we examined the causes of privacy concern and related factors in personalized recommendation service of OTT. On the basis of the 'Big Five Personality model,' we established factors such as agreeableness, neuroticism, conscientiousness, extraversion, and openness to experience. Additionally, we established factors such as accuracy, diversity, and novelty of OTT recommendation's services, and perceived transparency. we analyzed the relationship between privacy concern, service benefit, and intention to give personal information. Finally, we analyzed the mediating effect of service benefits on the relationship between privacy concern and intention to give personal information. The results of this study showed that (1) neuroticism, extraversion and openness to experience had the significant effects on privacy concerns, (2) perceived transparency had the significant effects on privacy concern, 3) privacy concern and service benefit had the significant effect on intention to give personal information, and (4) as a result of multi-group analysis towards low and high groups to verify the moderating effect by service benefits, a significant difference was observed between privacy concern and intention to give personal information. The findings of the study are expected to help the OTT firms' understanding towards users' privacy protection behaviors.

In this paper, I propose that what factors affect logistics companies' adoption of blockchain technology and to analyze the effects of blockchain technology on logistics performance. The variables influencing the adoption of blockchain technology were presented based on the TOE frame. Expected profit, organizational readiness, technology compatibility, and competitive pressure were suggested as factors to adopt blockchain technology. Also, as a blockchain technology, smart contracts and information transparency were presented. Logistics performance suggested agility and alignment. A survey was conducted with Korean logistics companies. Looking at the results of analyzing the collected data, it was found that expected profit and technology compatibility have a positive effect on this blockchain technology (smart contract, information transparency). Organizational readiness was found to have a positive effect on information transparency. Blockchain technology was found to have a positive effect on logistics performance.

'Trust' is 'believing and relying on people or things', and at the same time, it is the foundation and essential condition of existence of a specific community or society. How blockchain technology creates trust can be found in the fact that it is a technology shared by all participants. As a shared technology, blockchain itself shows three characteristics: transparency, immutability, and availability. Because it is shared, it is transparent, and because it is shared, it is immutable, which is difficult to modify or delete. In addition, since it is shared, the entire system operates normally even if some failure occurs. The significance of trust created based on this blockchain technology can be summarized in three aspects as follows. The first is to understand the problem of trust in connection with technology. Second, understanding the relationship between information and trust begins to pay attention. Third, based on the expanded information processing capability, it is possible to establish a large-scale, concrete relationship without central mediation.

This paper proposes a power management scheme for sensor nodes in wireless sensor networks based on sensor node operating system supporting the sensor transparency, which can turn off the sensors when the MCU is in sleep mode. We classify the sensors in two types, that is, event sensors and polling sensors, to be able to decide whether the sensor is a type of sensors whose power supply can be turned off or not, and we design a new scheduler to support recognition of those different types of sensors. Implementing and evaluation of the scheduler and the power manager supporting sensor transparency are shown based on Nano-Q+.

Pure functional languages have the referential transparency feature sothat all objects cannot be updated destuctively. Once an aggregated data structure such as array is updated, both the original and newly updated array must be preserved to maintain reverential transparency. Thus, it is required to develop an efficient mechanism with which can reduce the maintenance cost while maintaining referential transparency for whole data. This study is to suggest a functional array to solve the problem, and them test it. For that, the proposed mechanism was implemented on a combinator graph reduction machine. The result shows that proposed mechanism reduces traversal time for array operations. Also, updating all versions and accessing the recent version are achieved in constant time without reconstruction of updated data in execution time.
