고품질, 고 신뢰도를 지향하는 미래 지능형 전력시스템에 대한 기대와 함께 전력 기기 및 설비의 디지털화에 관심이 집중되면서, 전력시장에서는 전력정보의 양방향 교환 표준을 위한 공통정보모델(CIM : Common Information Model)의 개발 및 활용이 새로운 화두로 부상하였다. CIM은 차세대 전력시스템과 미래형 부가서비스 등의 전반적인 운영측면에서 혁신을 이루는데 사용할 수 있도록 표준화된 데이터교환 모델이다. 이는 전력시스템 내 모든 다양한 객체(변전소, 송전선, 변압기, 차단기, 설비자산, 작업지시, 작업원 등)들이 어떻게 상호 연결되는지를 표현하는 방식이다. 최근 CIM/GID(GID : Generic Interface Definition)에 대한 관심이 고조되면서 CIM/GID를 어떻게 도입하고 활용할 것인가에 대한 논의가 활발하다. 그 활용 방안의 일환으로 개발된 시스템에 대한 상호 운용성 테스트를 수행함으로써 제품 또는 시스템의 표준화 준수 여부와 활용성에 대한 검증이 가능하다. CIM/GID 상호운용성 테스트는 UCA International Users Group에서 가입 회원들을 대상으로 지속적으로 진행되고 있다. 본 논문에서는 미국 클리블랜드에서 2003년 11월 18일$\sim$20일 사이에 진행되었던 5차 CIM/GID 상호운용성 테스트 결과를 토대로 CIM/GID와 CIM XML의 상호 운용성 테스트 방안을 소개하고자 한다.

제64차 국제도서관연맹(IFLA)대회가 ‘정보와 문화의 교차로에서’라는 주제아래 8월 16일부터 21일까지 네덜란드 암스테르담에서 개최되었다. IFLA 총회가 네덜란드에서 개최된 것은 1939년 헤이그와 암스테르담, 그리고 1966년 쉐베닝겐에서 열린 데 이어 이번이 세 번째이다. 이번 대회는 공식집계에 따르면 세계 120개국에서 3,328명의 도서관인들이 참가하는 대성황을 이루었다고 한다. IFLA 대회는 회원국을 순회하면서 열리는데 지난해에는 덴마크 코펜하겐에서 열렸다. IFLA는 1927년 창설된 비정부기구로서 UNESCO와 함께 공식적으로 활동해왔다. IFLA의 목적은 도서관 활동과 문헌정보학 전반에 걸친 국제적인 이해와 협력, 토론, 연구 및 개발을 증진시키고 도서관인들이 국제적인 공동 관심사를 논하는 장을 제공하는 데 있다. 현재 회원으로 141개국 1400이상의 도서관 및 관련 단체들이 가입되어 있다. IFLA조직은 헤이그에 본부를 두고 있으며, 운영 조직으로 심의 평가를 담당하는 실행위원회와 전문위원회 그리고 4개의 자문위원회로 구성되어 있다. 실행위원회는 IFLA의 정책, 운영과 재정에 대하여 책임을 지어, 전문위원회는 두 개의 하부조직인 전문가 그룹과 5개 코아 프로그램에 의해 수행되는 전문적인 활동의 기획과 프로그래밍에 대하여 모니터 한다. 전문가 그룹이란 8개의 부회와 그 아래있는 34개의 분과와 11개의 원탁회의를 말한다. IFLA대회는 한국도서관협회가 주최하는 전국도서관대회보다 좀더 규모가 큰 행사라고 생각하면 상상하기가 쉬울 것이다. 대회 전체를 아우르는 주제가 설정되어 있고, 그 아래 각 분과별 발표회 또는 원탁회의가 동시에 여러 곳에서 진행된다. 따라서 참가자는 프로그램을 보고 자신이 참석할 분과나 포럼 등을 미리 정해두지 않으면 우왕좌왕하게 된다. 그리고 참석기간 중에는 매일 발행되는 를 반드시 참고할 필요가 있다. 이 자료는 IFLA 대회 일정의 변경이라든가, 하루 동안 일어난 소식을 알려주는 일종의 신문과 같은 역할을 한다.

This study attempts to describe and periodinate the sixty years history of Korean Geographical Society. For the purpose, several numerical records concerned with the society were employed. The Korean Geographical Society was established in 1945 as a first academic society in geography. The international participation of Korean geographers started when it applied for the IGU membership in 1959. Next year, Korean's application was approved at the 19th IGC in Stockholm. The 40 years later, Korea came to host the 29th IGC in Seoul. This means that the activity of Korean geographers has been vigorous during the 40 years in accordance with high growth of Korean economy. The number of the society member reached 116 in the latter part of 1960s. It grew steadily from 1970s to 1990s and now amounts to around one thousand. It is believed that such trend is associated with the increase of geographical department and the development of graduate programs during past 40 years in Korea. The number of the advanced degree holders was only 2 in 1960, and now reachs 338 among which 166($43\%$) obtained from the foreign country. The Int issue of the society journal 'Geagraphy' -the title was changed to 'Journal of the KGS' in 1993-was published in 1963. It has gradually developed into the annual for $1966{\~}1973$, the semi-annual for $1974{\~}1990$, the quaterly for $1991{\~}1997$, and the hi-monthly until 2005. One issue per year has been published in English since 1993. The annual number of papers accepted by the editorial board has increased from 7 in 1960s-1970s to 52 in the new millennium. In terms of the specialty distribution of total 725 papers after 1963, many Korean geographers have been preferable to the field of socio-economic and urban geography as their major, and next histro-cultural and physical geography. Recently, a growing number of younger geographers are more interested in such diversified fields as ecological geography, socio-historical geography, applied geography concerned with GIS technic, geography education and so on. Such trend is a reflection of the new era which is characterized by diversity, software, high technology, globalization and others. The sixty years history of the society nay be summarized into the five phases of periodization: (1) establishment and chaos($1945{\~}1959$), (2) reconstruction(1960${\~}$1969), (3)reorganization(1970${\~}$1989), (4) jump and rush($1990{\~}1999$), (5)globalization($2000{\~}\;$).

High Internet usage and the public's keen interest on health have influenced the health care system, and a potential value of the online health information and medical consultation market is immense. This study reveals results from data collected from Seoul residents in the age group of 20s in 2011. Out of 499 respondents, 75.2% answered that they used online health information; however, only 7.2% answered that they have used online medical consultation services. Findings on the purposes of using online medical consultation included treatments of symptoms(33.6%) and self-disciplines of one's health(19.5%). Mostly used Websites for health information search included search engines and blogs, but respondents preferred to use government sites and hospital sites in the future. When choosing a medical consultation, respondents preferred a certain website for different reasons including creditability of the consultant(23.7%), creditability of the organization(23.7%), rapid responses(21.2%), and more. Overall, although health information search via web is being highly utilized among people in their 20s, utilization of online medical consulting is not. Thus, promotion efforts to increase awareness and utilization of online medical consulting based on the site selection criteria, type of personal information disclosure, and other preferences are essential. Also, creating websites meeting these criteria is important.

Many web services which use OAuth Protocol offer users to log in using their personal profile information given by resource servers. This method reduces the inconvenience of the users to register for new membership. However, at the time a user finishes using OAuth client web service, even if he logs out of the client web service, the resource server remained in the login state may cause the problem of leaking personal information. In this paper, we propose a solution to mitigate the threat by providing an additional security behavior check: when a user requests to log out of the Web Client service, he or she can make decision whether or not to log out of the resource server via confirmation notification regarding the state of the resource server. By utilizing the proposed method, users who log in through the OAuth Protocol in the public PC environment like department stores, libraries, printing companies, etc. can prevent the leakage of personal information issues that may arise from forgetting to check the other OAuth related services. To verify our study, we implement a Client Web Service that uses OAuth 2.0 protocol and integrate it with our security behavior check. The result shows that with this additional function, users will have a better security when dealing with resource authorization in OAuth 2.0 implementation.

Radionuclide sorption data is necessary for the safety assessment of radioactive waste disposal. However the use of sorption database is often limited due to the accessability. A web-based sorption database program named KAERI-SDB has been developed to provide information on the sorption of radionuclides onto geological media as a function of geochemical conditions. The development of KAERI-SDB was achieved by improving the performance of pre-existing sorption database program (SDB-21C) developed in 1998 and considering user's requirements. KAERI-SDB is designed that users can access it by using a web browser. Main functions of KAERI-SDB include (1) log-in/member join, (2) search and store of sorption data, and (3) chart expression of search results. It is expected that KAERI-SDB could be widely utilized in the safety assessment of radioactive waste disposal by enhancing the accessibility to users who wants to use sorption data. Moreover, KAERI-SDB opened to public would also improve the reliability and public acceptance on the radioactive waste disposal programs.

In 2008, ETRI developed a new mobile digital ID wallet, in which anyone can store personal information and PKI credential. When the wallet is used, privacy protection is one of the most important problems and personal information should be protected under various usage scenarios such as exchanging sensitive information in on/off-line environments, joining as a new member in the web site, etc. In this paper, we propose a triangular trust management scheme that can effectively manage trustness and also protect sensitive personal information. This scheme relies on three techniques: PKI, reputation and condition (situation context). We implemented prototype of our scheme, and tested it under various scenarios, which showed that the proposed scheme can effectively be used for diverse cases.

This study was a pilot test of serious educational game content(named Roly Poly 160) designed to enhance self-care by elderly diabetics. Roly Poly 160 was developed in eight steps (literature review, demand survey and consultation, extraction of serious content using games, development of Roly Poly 160, pretest for users, workshop for health care workers, final completion of Roly Poly 160 and user satisfaction survey of Roly Poly 160). Roly Poly 160 is intuitively structured in three modules (self-management, card games, and quiz games) that can be self-managed by the elderly and is designed based on six principles. First, we constructed an intuitive interface considering the age of users. Second, the menu was selected as the main menu for Koreans and calorie learning was made at the same time. Third, the calories and nutrients (carbohydrate, fat, protein, calcium, sodium) of selected foods are analyzed, and all test data recorded in the questionnaire chart are graphically displayed by year, month and week so that the change trends can be grasped at a glance. Fourth, necessary data were saved and output and used as educational data. Fifth, user data are made compatible and aggregated and up to 100 million members can be registered. Sixth, it is designed to be developed as a mobile app if necessary. Using Roly Poly 160, 119 diabetic patients were diagnosed with diabetes, and the satisfaction score was 4.26 out of 5. These findings indicate that Roly Poly 160 is appropriate as a diabetes self-care tool and suggests that there is a possibility to use it as a program to educate people about diabetes in public health centers, hospitals and clinics.
