연구는 수도권을 중심으로 한 4년제 대학의 교육목표와 그에 따른 입학실기시험의 유형을 분석하여 학교별 특성화의 방향을 살펴본 결과 다음과 같은 효과를 기대할 수 있으리라 생각된다. 첫째 수요자인 고교에서대학의 정확한 정보를 통한 입시준비를 할 수 있게 한다. 둘째 애니메이션에 적합한 표준 실기시험유형을 도출할 수 있다. 셋째 대학입시에 대한 객관성과 투명성 그리고 신뢰성을 줄 수 있다. 넷째 대학 스스로는 특성화를 강화하는 단초로 활용하며 예비자원인 수험생들에게는 차별화된 대학의 특성화 정보를 제공한다.

본 논문에서 구축된 VDFS는 소형 시스템내에서 현존하는 NFS와 RFS 같은 대칭형 화일 시스템 구조들에서 나타나는 문제점들을 해결한 비대칭형 분산 화일 시스템을 제안하였다. 특히 본 논문에서는 중점적으로 다루어질 부분은 공유 화일의 중복 사용 을 통해서 보다 많은 투명성(Transparency)을 제공하고 캐슁 기반으로 한 원격 화일 서비스를 한층 더 증가시켜 서버 부하와 통신량을 감소시키므로 시스템의 성능을 향상 시키는데 있다.

Today's modern world requires a digital watermarking technique that takes the redundancy of an image into consideration for embedding a watermark. The novel algorithm used in this paper takes into consideration the redundancies of spatial domain and wavelet domain for embedding a watermark. Also, the cryptography-based secret key makes the algorithm difficult to hack and help protect ownership. Watermarking is blind, as it does not require the original image. Few coefficient matrices and secret keys are essential to retrieve the original watermark, which makes it redundant to various intentional attacks. The proposed technique resolves the challenge of optimizing transparency and robustness using a Canny-based edge detector technique. Improvements in the transparency of the cover image can be seen in the computed PSNR value, which is 44.20 dB.

Blockchain is at the center of attention recently and it is expected to have a huge impact on healthcare industry including dentistry as well. Blockchain is a fundamental technology behind Bitcoin and itis all about decentralization, security, reliability, and transparency. These characteristics of the technology empower it to disrupt the current healthcare industry in innumerable practices such as supply chain management in pharmaceuticals to prevent the counterfeited medicine, clinical trials to guarantee transparency, healthcare information exchanges or personal health record systems to ensure data integrity and interoperability, etc. It will surely revolutionize the way the current healthcare system works; from provider-oriented to patient-centered. Hence, it is time to seriously consider how we could be a part of this blockchain revolution in dentistry.

온라인 거래에서, 투명성은 전자상거래에 대한 과세나 고객의 권리를 위한 주요 요소이다. 오프라인에서 거래에 대한 신뢰성은 금전등록기 개념을 사용해서 이루어지고 있는 것처럼, 우리는 거래의 투명성을 위한 온라인 개념의 거래 등록기 모델을 연구하였다. 비록 온라인 거래 등록기가 전자상거래법과 관련되어서 사용될 수 있지만, 여기서는 등록기의 메카니즘에 대한 연구만을 고려하였다. 거래 등록기는 디지털 영수증을 발행하며, 영수증은 본 논문에서 개발한 모델로 진위가 판별될 수 있다.

The study aims to investigate the relationship between hedging with derivatives and subsequent firm-level stock price crash risk. Our sample consists of KOSPI- and KOSDAQ-listed companies from 2004 to 2014. The total firm-year observation is 4,886. We find that hedging with derivatives is related to greater possibilities of crash risk. The results suggest that the complexity of economic and financial reporting for derivatives may aggravate the company's information opacity, ultimately increasing the crash risk. We contribute to the growing body of literature on hedging with derivatives. Academics and practitioners have debated on whether or not hedging enhances transparency or rather makes the information environment more opaque. Theoretical research on the role of corporate hedging on information environment shows that hedging enhances earnings informativeness. Meanwhile, pieces of anecdotal and empirical evidence show that the economic and financial reporting complexity of derivatives can harm information transparency. Our results shed light on the question of whether and how hedging with derivatives affects information environment by examining the relationship between hedging with derivatives and crash risk. Furthermore, our findings provide useful insights for policymakers and practitioners. Specifically, our results raise a need for a more transparent disclosure on corporate hedging activities with derivatives.

This study investigates the application of management information systems to the quality of local government financial reports, especially the principle of transparency and the law of accountability, which have been measures of financial statement performance evaluation. The study was conducted in Enrekang Regency, Indonesia, which, based on the results of the examination, the Supreme Audit Board reported the status of Disclaimer, Fair with Exceptions, and Fair without Exceptions for three years each. This study used a sample of 35 respondents, finance department employees who worked on local government financial reports. Descriptive quantitative data were collected using a questionnaire instrument, then with the assistance of the Program Solution and Product Statistics (SPSS) Program, data were processed to test hypotheses. The results showed that the use of management information systems based on information and communication technology (ICT) had a significant influence on the quality of local government financial reports. The findings of this study indicate that the application of ICT-based management information systems affects the accountability and transparency of local government financial reports. This finding is reinforced by the use of the principles of government agility in the form of government apparatuses that apply responsive dexterity, flexibility agility, and competency agility.

Recently, the electromagnetically-induced transparency (EIT)-like effect in metamaterials has attracted enormous interest. Metamaterial analogs of EIT enable promising applications in slow-light devices, low-loss metamaterial, quantum optics, and novel sensors. In this work, we experimentally and numerically studied a bilayer metamaterial for controllable EIT-like spectral response at microwave frequencies. Bilayer metamaterial consists of two snake-shape resonators (SSRs) with one and two bars. The transmission spectra were measured in a frequency range of 4 - 8 GHz in an anechoic chamber at normal incidence. It is found that two SSRs in the metamaterial are activated in bright modes, and the coupling between two bright modes leads to the EIT-like effect, which results in the enhanced transmission at 5.61 GHz. Furthermore, we confirm that the EIT-like feature could be controlled by adjusting the geometric parameters of metamaterial structure. Our work provides a way to tunable EIT-like effect and various potential applications including filters, sensors, and other microwave devices.

This research aims to identify the determinants of e-government satisfaction in Hanoi, Vietnam, and assess their impact. To collect data, we conducted an online questionnaire with citizens living in Hanoi in a time span of five weeks. We received 1,107 responses, divided into three groups: unaware, known, but not used, and used e-government. After leveraging past studies on satisfaction in different contexts, we arrived at six external variables that are of particular relevance to e-government satisfaction (i.e., efficiency, trust, reliability, convenience, citizen support, and transparency) as well as four control variables (i.e., age, gender, education level, and Internet frequency). We then applied both SPSS 22 and STATA 2016 to process and analyze the collected data and found that, while almost all external variables are statistically significant, all four control variables are not. Apart from convenience and trust, four factors - efficiency, reliability, citizens support, transparency - are important measures of system quality, information quality, service quality and relative benefits of e-government, which in turn positively and significantly impact citizens' satisfaction with the online public services. Furthermore, the efficiency variable has the most influence on customer satisfaction, and the level of impact on the dependent variable decreases in the following order: citizen support, reliability and transparency.
