  • The purpose of this study was to examine the reliability and validity of Stroke Impact Scale 3.0 (SIS 3.0). Here, the SIS 3.0 was completed by 154 stroke patients (mean = 62.7; standard deviation [SD] = 9.43). Construct validity was verified by analyzing the correlation between SIS 3.0 sub-domains, and convergent validity was investigated by analyzing the correlation between the Modified Barthel Index (MBI) and the Mini-Mental State Examination-Korean (K-MMSE) version. The characteristics of each item were analyzed by internal consistency and item discrimination based on the classical item theory. Construct and convergent validity were verified through this study. Although the item i included in the emotion domain showed low item discrimination, all but this item showed high discrimination. Internal consistency was also high in all sub-domains.

  • The purpose of this study was to investigate the convergence between ego-resilience, major satisfaction and clinical competency of nursing students. This study used data from 183 nursing college students who experienced clinical practice at a college located in G city of Korea. Clinical competency was positively correlated with ego-resilience (r = .446, p <.000), major satisfaction (r = .439, p <.000). The factors influencing clinical competency were ego - resilience and major satisfaction, and explanatory power was 29.1%. Based on the above results, it is necessary to improve the convergence education program and diversify the teaching and learning methods to improve the major satisfaction, ego - resilience and clinical competency of nursing students.

  • This study aims to apply the mathematical method of fractional order derivatives to the controller that controls the system response. In general, the Laplace transform of the PID controller has an exponent of the integer order of s. The derivative of the fractional order has a fractional exponent of s when it is transformed by Laplace transform. Therefore, this controller proposes a design method with the result of discrete time conversion. Because controllers with fractional exponents of s are not easy to design. This controller is applied to a standard secondary system and its performance is examined. Then, it applies to solenoid valve which is widely used in industrial field. A Luenberger's observer was designed to estimate the disturbance state and the observed state was applied to the fractional order controller. As a result, uniform and precise control performance was obtained. It was confirmed that the position error of the steady state is within 0.1 [%] and the rising time is within about 0.03 [s].

  • In 2016, the number of suicides per 100,000 population in Korea was 24.6, which is the highest record of OECD countries. The number of suicide deaths increased with age. Elderly people have a higher risk of completed suicide than any other age group. The purpose of this study was to analyze the panel data of the Korean Welfare Panel Study to identify the factors affecting the suicide of Korean older people. This study analyzed the data of the 11th Korean Welfare Panel Study, which was constructed in 2016. The mean age of the participants was 75.55 years and 37% were man and 63% were women. The annual prevalence of suicidal ideation was 3.4%. The effects of depression(Exp(B)=1.113) and subjective health status((Exp(B)=.767) on suicidal ideation was statistically significant by stepwise logistic regression analysis(Nagelkerke $R^2=.248$). Therefore, for the effective application of suicide prevention program for the older people, assessment of subjective health status and depression screening should be preceded.

  • This research empirically investigated halo effect in evaluating culture and art performance program. We diagnosed halo effect by using correlation analysis, factor analysis, and regression model on results and scores of fifteen evaluation indicators within three categories for the 107 Local Representative Performance Art Festivals in 2014 and 2015. The results indicates strong possibility of halo effect in culture and art performance evaluation. The correlation coefficients between evaluation indicators is higher than 0.5 and factor structure does not match with evaluation categories in both years. Scores in categories and standard deviations also are also significantly correlated with each other. The results implies that more sophisticated standard, diversification of evaluator, education, and meta-anlysis are need to control halo effect.

  • This study is a descriptive research to measure the awareness and attitude toward withdrawal of life-sustaining medical treatment (WLSMT) among medical and nursing students. The data collection was conducted between 8 October and 15 November 2018, and the responses of 240 students were analyzed. The analysis results are as follows. More than 95 percent of medical and nursing students said the WLSMT was necessary. The medical students answered that 'patient's will' is important and nursing student answered that 'patient and family's will' is important. The nursing student showed that "family will and decision" was more important than the medical student in deciding to discontinue life care. Based on the results of the study, continuous discussion on the development and application of education programs to form attitudes and awareness of the discontinuation of life-saving treatments based on correct values is needed for prospective medical students and nursing students.

  • Federated authentication is a user authentication and authorization infrastructure that spans multiple security domains. Many overseas Web applications have been adopting SAML-based federated authentication. However, in Korea, it is difficult to apply the authentication because of the high market share of a specific Web (application) server, which is hard to use open-source SAML software and the high adoption of Java-based standard framework which is not easy to integrate with SAML library. This paper proposes the SAML4J, which is developed in order to have Web applications easily and safely integrated with the Java-based framework. SAML4J has a developer-friendly advantage of using a session storage independent of the framework and processing Web SSO flows through simple API. We evaluate the functionality, performance, and security of the SAML4J to demonstrate the high feasibility of it.

  • 효과적인 물 사용과 물 관리 정책을 수립하기 위해서는 산업적 차원에서의 물 발자국 연구를 통해 산업 전반적인 수자원 활용 상황을 비교 분석할 필요가 있다. 또한 앞으로 국가 차원의 물 안보 정책을 수립하기 위해서는 기후변화와 국제환경 변화로 인해 우리나라의 물발자국 변화를 예측하는 것이 필수적이다. 국외에서는 일찍이 물과 환경전문 교육기관인 UNESCO-IHE를 중심으로 물발자국 산정방식의 이론적 연구와 함께 가상수 무역에 대한 연구를 진행해왔으며, 국제표준화기구(International Organization for Standardization, 이하 ISO)는 2014년 물발자국에 대한 가이드라인을 국제표준으로 지정하였다. 국내에서는 2009년 가상수와 물발자국에 대한 이론이 소개되어 공공기관의 주도로 가상수 및 물발자국과 관련된 연구가 진행되어 왔다. 이러한 연구결과를 바탕으로 데이터베이스를 구축하기도 하였으나 1차 산업 위주로 구성되어 있어 2차, 3차 산업 등 다른 산업에 대한 정보는 부족한 상태이다. 따라서 앞으로는 2차, 3차 산업 등에 대한 연구가 필요하다. 국제 가상수 거래의 도출을 위한 기초자료로서 WIOD의 input-output tables와 environmental accounts 등을 활용하였다. 본 연구에서는 생산량, 물사용량과 관련된 지표를 결합하여 가상수량을 도출하는 과정을 제시하고, 가상수 이동흐름 및 추이를 분석하였다. 이를 위해 주요 16개국(아르헨티나, 호주, 브라질, 캐나다, 중국, 프랑스, 독일, 인도, 일본, 한국, 러시아, 사우디아라비아, 태국, 미국, 베트남)의 농축산물 주요 10개 품목(쌀, 보리, 옥수수, 밀, 콩, 감자, 채소, 소고기, 돼지고기, 계란)을 대상으로 분석을 실시했다. 또한 국가별 가상수 교역량, 국가 간 가상수 교역량에 대한 1989년부터 2014년까지의 데이터셋을 구축하고 이에 대해 분석을 수행하였다. 가상수 교역의 품목별 분석결과 주요 16개국의 주요 가상수 수입 품목은 콩, 옥수수, 밀, 보리 순이며, 주요 가상수 수출 품목은 밀, 콩, 옥수수, 쌀 순으로 파악되었다. 가상수의 종류별로 분석한 결과 가상수 교역량은 지난 25년간 녹색 가상수가 94%의 압도적으로 많은 비중을 차지하고 있었다. 국가별로 가상수 수출입량을 분석한 결과 1989년에서 2013년까지 미국, 브라질, 아르헨티나, 호주 등 주요 농업 국가들이 전 세계 가상수 수출에서 우위를 점하고 있는 것으로 분석되었다.

  • Study and analysis on the digital certification of the world today, and census on how digital signature is being used or considered for the government will be used to sum of what can be the difficulties and Problems in operating digital signature certifications for the government administrations at this research, and of course the answers to these problems will be provided too. This research suggests practical ideas on how to interoperate between Government PKI (GPKI: Administrational Digital Certification for the Government) and National PKI (NPKI: Digital Certification for General Public &Business), how to make use of Standard Security APIs, how to manage (e.g. issue, reissue, update, revoke) digital certificate, how to improve technical side of security and reliability, and how to improve political issues on public education for information security. Digital certification will become more popular and widely used in government administrations in the future. Therefore, census and research on demands md satisfactions of digital certification for public and government will be regularly performed. Of course, continuous maintenances and improvement in this field will be necessary to obtain firmer way of information security.

  • Reducing handoff latency is essential in providing seamless multimedia service in Wireless LAN based on the IEEE 802.11 standard. Reducing authentication delay is critical in reducing handoff latency. To this end, several authentication protocols for fBst handoff have been proposed. Mishra et al. used proactive key distribution to improve the authentication delay incurred in the current standard and Park et al. proposed a new authentication protocol based on Blom's key pre-distribution scheme. In this paper, we propose an enhanced authentication protocol based on Bresson et al.'s group key protocol. If a mobile node has previously access the network, our proposed protocol only requires simple hash operations in providing mutual authentication between a mobile node and access points. Our protocol is more efficient than Park et al.'s and Mishra et al.'s technique can be used in our protocol to further enhance our protocol.
