Recently several hospitals have established a new nursing position so called, 'the nurse in charge of education (NCE).' The job description of NCE is to give a detail explanation on examination or test introduced to patients or a guide for those who are not familiar to hospital facilities at the out-patients level. The motivation of NCE position is the quality improvement in patient education on the sophisticated procedures or the follow up care for medical purposes to improve their compliances, as well in delivering services for outpatients or visitors in more informative and efficient way. The application of NCEA has been turned out positive and effective in patient satisfaction and unit management. However, special attention is brought to the scope and depth of the contents of education delivered by NCE which might overlap with the duty of physicians by the Medical Act. It is needed to clarify the role and job description of NCE in the context of Medical Act. The engagement of NCE to the Advanced Nursing Practitioner (ANP) is one of the possible solutions for a duty charge on patient education since ANP is a legislatively official position with higher license of RN at master level. Further discussion is needed to elaborate and arrange the details on the scope and content of patent education among health science professionals including RN, ANP and physicians.

시맨틱 웹과 웹 2.0의 개념이 등장하며 시작된 차세대 웹은 기존의 자원 중심의 서비스를 바꾸고 있다. 즉, 관심의 초점이 이미 풍부해진 자원 자체가 아닌 그 자원을 설명하는 메타 정보로 옮겨지고 있는 것이다. W3C와 ISO에서는 이러한 메타 정보를 기술하기 위한 표준으로 각각 RDF(Resource Description Language)와 토픽맵(Topic Maps)을 정의하여 발표하였다. 그러나 메타 정보를 XML형태로 직접 기술하는 방법은 사용자 참여가 중요시되는 차세대 웹에서 일반 사용자들의 진입을 막을 수 있다. 이러한 문제 해결의 한 방법으로 기존의 WikiWikiWeb 시스템을 확장한 시맨틱 위키(semantic wiki)가 등장하였으며 사용자는 간단한 문법을 통해 위키 페이지에 대한 RDF 메타 정보를 생성할 수 있게 되었다. 본고에서는 토픽맵 기반의 시맨틱 위키와 현재 구현된 RDF 기반의 시맨틱 위키 사이의 메타 정보 상호운용성을 위한 방법을 RDFTM Task Force에서 제시한 방법론을 기초로 살펴보고, 상위의 Wiki 문법을 통해 하위 단의 변환문제가 자연스럽게 해결될 수 있음을 보인다.

레이다 시스템의 경우, 타겟의 거리와 속도를 추출하기 위해 FFT (fast Fourier transform) 연산이 필수적으로 요구되며, 실시간 구현을 위해 고속으로 동작하는 FFT 프로세서의 설계가 필요하다. 고속 FFT 프로세서를 위한 하드웨어 구조로 완전 셔플 네트워크 (perfect shuffle network) 구조가 적합하며, 특히 초고속 연산을 위해 radix-4 기반의 이중 완전 셔플 네트워크 (twice perfect shuffle network) 구조가 가장 적절하고 볼 수 있다. 더불어, 다양한 속도 해상도를 요구하는 레이다 응용을 고려할 때, FFT 프로세서는 가변길이 FFT 연산을 지원할 필요가 있다. 이에 본 논문에서는 8~1024 포인트의 가변 길이 연산을 지원하는 이중 완전 셔플 네트워크 기반의 FFT 알고리즘을 제안하였으며, 이의 하드웨어 구조 설계 및 구현 결과를 제시한다. 제안된 FFT 프로세서는 HDL (hardware description language)을 활용하여 RTL (register transfer level) 설계가 수행되었으며, $0.65{\mu}m$ CMOS 공정을 활용하여 논리 합성한 결과, 총 3,293K개의 논리 게이트로 구현 가능함을 확인 할 수 있었다.

The use of multi scale modeling concepts and simulation techniques to study the destabilization of an ultrathin layer of oxide interface between a metal substrate and the surrounding environment is considered. Of particular interest are chemo-mechanical behavior of this interface in the context of a molecular-level description of stress corrosion cracking. Motivated by our previous molecular dynamics simulations of unit processes in materials strength and toughness, we examine the challenges of dealing with chemical reactivity on an equal footing with mechanical deformation, (a) understanding electron transfer processes using first-principles methods, (b) modeling cation transport and associated charged defect migration kinetics, and (c) simulation of pit nucleation and intergranular deformation to initiate the breakdown of the oxide interlayer. These problems illustrate a level of multi-scale complexity that would be practically impossible to attack by other means; they also point to a perspective framework that could guide future research in the broad computational science community.

At present, the main method of high-speed train chassis detection is using computer vision technology to extract keypoints from two related chassis images firstly, then matching these keypoints to find the pixel-level correspondence between these two images, finally, detection and other steps are performed. The quality and accuracy of image matching are very important for subsequent defect detection. Current traditional matching methods are difficult to meet the actual requirements for the generalization of complex scenes such as weather, illumination, and seasonal changes. Therefore, it is of great significance to study the high-speed train image matching method based on deep learning. This paper establishes a high-speed train chassis image matching dataset, including random perspective changes and optical distortion, to simulate the changes in the actual working environment of the high-speed rail system as much as possible. This work designs a convolutional neural network to intensively extract keypoints, so as to alleviate the problems of current methods. With multi-level features, on the one hand, the network restores low-level details, thereby improving the localization accuracy of keypoints, on the other hand, the network can generate robust keypoint descriptors. Detailed experiments show the huge improvement of the proposed network over traditional methods.

Growth of researches addressing cross-culture in international business is exponential. This article reviews the extant researches around the national culture and describes the various conceptualization of culture through discussion of some of popular models of national culture. This article presented some of the most important issues in international business surrounding globalization, especially convergence and divergence of cultures and cultural changes. Global rapid changes in international business environment request the reconsideration of the assumption of cultural stability and the simple view of culture, which tends to examine the static influence of a few cultural factors in isolation form other cultural factors and contextual elements. This paper identifies a valid cultural grouping and proposes the following typology of the possible methodologies in international business; Ethnological description, Use of proxies, Direct values inference, and Indirect values inference. Rather than selecting a single methodology, it appears to be more appropriate to use multi-method in the cross-cultural international business research. It has been shown that cultural change is intertwined with socioeconomic-institutional variables, and that these variables may also add to determine culture contemporarily. This paper also explained the dynamics of culture as multi-level, multi-layer constructs. According to this model, we may understand how the dynamic nature of culture conveys the top-down-bottom-up processes where one cultural level affects changes in other level of culture.
