신나연,박점미 한국간호과학회 2018 Asian Nursing Research Vol.12 No.3

Purpose: This study examined the effects of intentional nursing rounds based on the care model on patients' perceived nursing quality and their satisfaction with nursing services. Methods: The study design was a nonequivalent control group pretest-posttest design. The participants were assigned to the intervention group or the control group in two orthopedic wards of a teaching hospital. A total of 9 rounds (at 7 AM, 9 AM, 12 PM, 3 PM, 5 PM, 8 PM, 10 PM, 2 AM, and 5 AM) were performed every 2 or 3 hours to the experimental group. The intentional nursing rounding intervention was developed through a theoretical development program involving six basic principles which are maintaining belief, knowing, being with, doing for, enabling, and patients' wellness. To evaluate the effects of intentional nursing rounds, data were collected through the Perception of Quality Nursing Care Scale and the Patients' Satisfaction with Nursing Care Quality Questionnaire. Results: The participants were 70 patients (experimental group) and 75 patients (control group). Results of difference-in-difference analysis confirmed that the patient-perceived nursing quality level from the experimental group was 0.85 points (out of 5.00) higher (p ¼ .041) and the satisfaction with nursing services level was 8.28 points (out of 110.00) higher (p < .001) than the control group. Conclusions: These results proposed that intentional nursing rounds based on the care model were effective in improving perception of quality nursing care and patients' satisfaction with nursing care. Structured patient-oriented intentional nursing rounds based on the care model are expected to expand to a variety of clinical settings further.

The restricted network or the unbalanced distribution of spectrum is causing the problems of lack of spectrum resources and deterioration of the service quality. In addition, the existing centralized radio sharing method has not been a fundamental solution for radio sharing and is inefficient in terms of cost, convenience, and security. In this paper, we propose a blockchain-based spectrum sharing as a low-cost, trustworthy, high-efficiency platform that can distribute and share spectrum resources, and propose policies to realize this. In the spectrum sharing platform, spectrum information about Wi-Fi AP and LTE mobile hotspot is registered in the blockchain, and spectrum sharers and users can conclude peer-to-peer spectrum sharing contract quickly and efficiently through smart contract. The pay for the shared spectrum resources and reward for spectrum quality management open platform ecosystem to activate the circulation-sharing and it can provide a convenient and efficient public wireless infrastructure. 제한된 네트워크 자원과 불균등한 전파 자원 분배로 인해 전파자원 부족 문제와 서비스 품질 열화가 발생하고 있다. 또한, 기존 중앙집중식 전파 공유 방식은 전파 공유 활성화를 위한 근본적인 해결책이 되지 못하고 있으며 비용, 편의성, 보안성 관점에서 비효율적이다. 본 논문에서는 전파자원을 분배하고 공유할 수 있는 저비용, 고신뢰, 고효율 플랫폼으로서 블록체인 기반의 스펙트럼 쉐어링 플랫폼을 제안하고 이를 실현하기 위한 법적 쟁점을 분석하였다. 스펙트럼 쉐어링 플랫폼에서는 와이파이 AP 전파 정보와 LTE 모바일 핫스팟 전파 정보를 블록체인에 등록하고, 전파 공유자와 전파 사용자가 스마트 컨트랙트 통해 개인 간 (P2P) 전파 공유 계약을 빠르고 효율적으로 체결한다. 전파 공유에 대한 대가와 품질 관리에 대한 보상인 암호화폐는 선순환적인 전파 공유 오픈 플랫폼 생태계를 활성화할 것이며, 스펙트럼 쉐어링 플랫폼을 통해 편리하고 효율적인 공공 무선 인프라를 제공할 수 있다.

신나연,이진민,노현,이일구 한국융합보안학회 2023 융합보안 논문지 Vol.23 No.1

Digitalization due to COVID-19 has rapidly developed artificial intelligence-based voice recognition technology. However, this technology causes unfair social problems, such as race and gender discrimination if datasets are biased against some groups, and degrades the reliability and security of artificial intelligence services. In this work, we compare and analyze accuracy-based unfairness in biased data environments using VGGNet (Visual Geometry Group Network), ResNet (Residual Neural Network), and MobileNet, which are representative CNN (Convolutional Neural Network) models of artificial intelligence. Experimental results show that ResNet34 showed the highest accuracy for women and men at 91% and 89.9% in Top1-accuracy, while ResNet18 showed the slightest accuracy difference between genders at 1.8%. The difference in accuracy between genders by model causes differences in service quality and unfair results between men and women when using the service. Covid-19으로 인한 디지털화는 인공지능 기반의 음성인식 기술을 급속하게 발전시켰다. 그러나 이 기술은 데이터셋이 일부 집단에 편향될 경우 인종 및 성차별과 같은 불공정한 사회적 문제를 초래하고 인공지능 서비스의 신뢰성과 보안성을 열화시키는 요인이 된다. 본 연구에서는 대표적인 인공지능의 CNN(Convolutional Neural Network) 모델인 VGGNet(Visual Geometry Group Network), ResNet(Residual neural Network), MobileNet을 활용한 편향된 데이터 환경에서 정확도에 기반한 불공정성을 비교 및 분석한다. 실험 결과에 따르면 Top1-accuracy에서 ResNet34가 여성과 남성이 91%, 89.9%로 가장 높은 정확도를 보였고, 성별 간 정확도 차는 ResNet18이 1.8%로 가장 작았다. 모델별 성별 간의 정확도 차이는 서비스 이용 시 남녀 간의 서비스 품질에 대한 차이와 불공정한 결과를 야기한다.
