최근 들어 전력 계통은 점차 복잡해지고 계통의 규모 역시 빠른 속도로 성장하고 있다. 한국전력거래소는 전력계통의 안정적, 경제적 운영을 담당하고 있는 기관으로 '01년 현재의 에너지관리시스템(EMS)를 도입하여 실시간 전력계통에 대한 정확한 판단을 기반으로 전력계통의 안정성과 경제성 확보에 주력하고 있다. EMS의 대표적인 기능은 계통데이터의 수집(SCADA), 자동발전제어(AGC), 계통해석(NA) 등으로 대별되며, 이중 계통해석 기능은 프로그램 규모면에서 가장 큰 부분을 차지하고 있다. 계통해석 기능은 또다시 상태추정(SE), 상정사고분석(CA), 안전도해석(SENH), 고장해석(SCT) 등의 프로그램으로 구성되어 다양한 실시간 계통해석을 수행하게 된다. 전력계통 해석은 먼저 대상계통을 수학적 모델로 정식화하기 전에 계통망의 기하학적 구조를 기술하는 단계가 필요한데 이를 토폴로지 처리라고 하며, 보통 그래프이론인 노트(Node)와 마디(Branch)를 사용하여 전력계통망을 구성하는 요소들의 연결관계를 정의하게 된다. 본고는 이론적 수준을 넘어 EMS의 계통해석 기능에서 실계통을 해석하기 위해 쓰이고 있는 토폴로지 처리의 기본 알고리즘을 분석하여 국내 전력산업 기술 선진화에 기여하고자 한다.

The goal of this study is to explore and draw implicaitons from international and domestic media and information literacy (MIL) policies and educational systems. To this end, international policy documents issued by UNESCO, IFLA, OECD, and the EU as well as domestic South Korean laws and policies related to MIL and the fuctions of public libraries and related institutions were analyzed. The findings show that international organizations recognize public libraries as institutions that are responsible for providing information access and supporting knowledge sharing for citizens within and outside of formal education systems. Additionally, public libraries are seen as institutions responsible for supporting lifelong learning and civic education, as well as improving media, information, and digital literacy skills of their communities. In South Korea, the Library Act gives public libraries and librarians responsibility for improving citizens' MIL to support the public's right to know and to narrow the information gap. However, the functions of public libraries and librarians in South Korea have been limited or excluded in the domestic MIL policies. This study concludes that public libraries and librarians are responsible for reducing the information gap among citizens and should actively participate in policy development to improve citizens' MIL skills.

This study was aimed to provide basic data which are fairly useful to improve satisfaction level of patients by analyzing factors related to each functional satisfactions of dental implant treatment. The subjects of this study were 120 patients who received implant treatment and analyzed with t-test, one-way ANOVA and pearson's correlation. The results of this study were as follows. 1. Differences of each functional satisfaction according to general characteristics was not reveal statistically significant. 2. A group to got periodic scaling and tooth brushed four or more times a day showed the highest satisfaction of social and esthetic function(p < .05). 3. A group to implantation in premolar area showed the highest satisfaction of masticatory function and a group to implantation in incisor to be high in satisfaction of social and esthetic function, but the differences were not statistically significant 4. A group to got implant treatment at a dental hospital showed the highest satisfaction of both social and esthetic function, and at a general hospital were found lowest(p < .05). 5. Masticatory function, social function, esthetic function, and overall satisfaction were found to be in a positive correlations, and especially, the correlation coefficient between the overall satisfaction and social function was found to be highest(p < .01).

In order to analyze factors that support effective health care delivery system, this study aimed to research general public's perception on the functions of medical institutions(based on the levels of treatment: primary care, secondary care, and tertiary care), choices of medical institution when contracted with an unfamiliar disease, and recognition of diseases based on their severities. We collected data using self-administered survey from 400 general public living in Seoul, S. Korea from April 25 to May 18, 2011. The analysis was conducted using frequency analysis, chi-square test, and t-test; we analyzed the data to see if there are differences based on gender, age, and level of education. The result of both recognition of functional differences of medical institutions and selection of medical institutions when contracted with unfamiliar diseases showed that there were no significant differences based on the gender; however there were significant differences when considering the age and education. Looking at the result of the knowledge of the disease classification based on its severity, there were significant differences in age, gender, and education. In order to provide sustainable and effective health care delivery system, utilization of primary care as well as education and promotion regarding the functional differences of medical institutions and classification of disease based on its severity need to be encouraged.

This study examined the experiences of users regarding their use of electronic informed consent in hospital. A qualitative descriptive study was conducted using focus groups and in-depth interviews with 30 Korean nurses and 27 patients. Data were collected from one university hospital. The responses were analyzed by qualitative content analysis. Most participants perceived the use of electronic informed consent as convenient and straightforward, as well as saving space and money. On the other hand, the participants stated that the system was unsatisfactory in part because of the occasional unexpected machinery error or malfunction. Some patients wished for function improvements related to the e-signature, making it more comparable to a handwritten signature, and the adjustability of the font size. The nurses wanted a wider implementation of electronic informed consent because it was not being used for all informed consent cases, resulting in confusion and an additional workload. For the use of an electronic informed consent system, it is important to minimize the inconvenience and to maximize the satisfaction of the users, including nurses and patients.

최근, 피싱 파밍 등 전자거래 환경의 보안위협의 크게 증가하면서 안전한 전자거래를 위한 다양한 인증기술에 대한 논의가 활발히 진행되고 있다. 본 논문에서는 이와 관련하여 ITU-T SG17 국제표준화기구에서 추진하는 OTP 기반 부인방지에 대한 표준안을 분석하고, 해당 프레임워크의 실제 전자거래 환경에 적용하기 위한 방안을 분석한다. 기존 전자거래 환경에서는 전자거래에 대한 부인방지 기능을 제공할 수 있는 기술로 공개키 기반의 전자서명이 주로 사용되었는데, 해당 표준안은 대칭키 기반의 일회용패스워드(OTP) 기술을 이용해서 부인방지 기능을 제공할 수 있는 새로운 방법을 제시하고 있다. OTP 부인방지 프레임워크는 사용자와 서비스제공자가 OTP 생성키를 이용해서 거래정보와 연계된 부인방지토큰 요청 메시지를 생성하고, 제3의 신뢰기관인 TTP를 통해 부인방지토큰을 생성 및 검증한다. 해당 프레임워크에서는 부인방지 서비스를 제공하기위한 4가지 서비스 모델을 제시하고 있어서, 전자거래환경에 맞는 서비스 모델을 선택적으로 적용이 가능하다.
