최근 인터넷을 통해 개인정보 유출사례가 빈번히 발생하고 있으며, 한번 유출된 개인정보는 회수 변경이 어렵고, 명의도용 사기 등 제3의 범죄로 까지 이어지고 있어 국가차원의 대책 마련이 요구된다. 현재 각 포털사(社) 쇼핑몰 등 인터넷 사업자는 회원 가입시 개인정보를 무분별하게 수집하고 있으며 제대로 된 보안관리가 이루어지지 않고 있는 실정이다. 이러한 상황은 시간이 지날수록 해커가 공격할 수 있는 취약 요인의 수만 증가 시킬 뿐이며 보안 관리 범위도 통제할 수 없게 된다. 또한 국내 외 해커들은 금전적 이득을 얻기 위해 개인정보를 선호하고 있어 향후에도 개인정보 유출 사고는 지속 증가할 것으로 예상된다. 이에 본 논문에서 인터넷 회원가입을 위해 수집하는 개인정보 보안 관리 실태를 살펴보고 유출된 개인정보를 인터넷에서 재사용할 수 없도록 하는 공인인증서 기반 개인 인증체계 개선 모델을 제안하기로 한다.

This study is conducted to find out whether companies which use electronic commerce for their business are collecting the least personal information. of consumers that are necessary for providing electronic commerce services to consumers. Investigators visited website of 799 electronic commerce companies, and checked out the personal informations of consumers that were asked when they join the site as a member. The collected data were analyzed with frequency, percentage, and cross-tab analysis using SPSS program. Generally most electronic commerces required more personal information of consumers than necessary for providing their services to consumers. These phenomena are partly due to the fact that regulations regarding consumer privacy in electronic commerce are advisory rather than mandatory at present. Therefore, it is suggested that mandatory regulation which makes companies poot their identification within a certain area of their web page has to enforced for the protection of consumer privacy in electronic commerce. And it would be more efficient if consumers are consistently educated about self protection guideline regarding personal information in using electronic commerce in addition to a mandatory regulation.

Small & medium sized company is the most efficient way of management to prevent my accident in the area of industry. Employees are more than 30 to less than 50 persons and which is liable for securing a safety manager on site, is gradually seen on the surface. Even a small company is nothing less than a dead zone from a safety since it's free from his obligation of employing a safety manager. Let us now think about the effective measures against a industrial accident by collecting, reviewing a variety of preventive measures, which is being carried out for preventing an industrial accident happening in a small company, and comparing, analyzing the effect according to the respective measures. Through this research, it's expected to contribute to both the development of small & medium sized company and our national economy with the improvement of a company's competitiveness and the accumulation of technical background by way of prevention from occurring industrial accident in a small & medium sized company, in accordance with an friendly environment of work room to protect the employee from leaving his job.

There are emerging issues to update the educational environment for schools in terms of information and communication technology in order to provide customized programs to students as well as all participants relating to learning and teaching. The past year has been turbulent as the education facilities has changed and new procurement processes such as BTL have emerged. In this study, the feasibility analysis of ICT for the public educational environment is to analyse the current primary schools by means of collecting parent's opinion. In the web-site questionnaires, it was designed with 70 items such as teaching method, class organization, aptitude drill and educational community. As results, the statistical analysis is to propose the list of priority and orientation covering social agenda in the issue of ICT for education, the benefits schools can achieve by smart environment is to have the advanced learning services and solutions that represents parental engagement with identical local aims of interactive interface between their students and qualified teachers at a school. Both the national curriculum as well as the after-school program initiatives from the ministry of education, science and technology may reduce negative effects of private education so that the program has to be carefully developed for balanced education society revitalizing mutual communication within regional learning participants such as students, teachers and educational experts.

최근 소셜 네트워크 사용자들이 늘어나면서, 각 지역에서 관심 받고 있는 사회적인 이슈나 재해 등과 같은 이벤트에 대한 정보들이 소셜 미디어 사이트를 통해 실시간으로 빠르게 대량으로 게시되고 있으며, 사회적 파급효과도 매우 커지고 있다. 본 논문에서는 지역정보를 가진 트위터 데이터를 이용하여 특정 시간, 지역에 사용자들이 관심을 가지고 있는 이벤트를 탐지하는 방법을 제안하고자 한다. 이를 위해 트위터 스트리밍 API를 이용해 데이터를 수집하고, 트윗의 키워드들의 시간에 따른 빈도수를 분석하여 정상적인 패턴과 다른 패턴을 가진 키워드를 이벤트로 추출하고, 같은 이벤트에 대한 키워드들을 군집화 하기 위해 co-occurrence 그래프를 이용하여 이벤트 감지 시스템을 구현하였다. 그리고 실험을 통해 제안한 기법의 유효성을 검증한다.

The purpose of this work was to study library website users' actions by tracking their behavior, determining popular content, and identifying browsing patterns and subsequent improvement of access to popular content. The study of behavior models and the use of web analytics has led to the emergence of solutions that improve the usability and functionality of the State Public Scientific-Technological Library of the Siberian Branch of the Russian Academy of Sciences (SPSTL SB RAS) website. These are: identifying user tasks as they are developed, conducting user testing to better understand the event. tracking data and collecting additional data to verify the effectiveness of the changes made. Examining data on the duration of the session and the number of visits will help determine the goals of user visits and develop new recommendations. Usability analysis and testing will make it possible to compare the data obtained using web analytics and the perception of the library site by the users themselves. Recommendations are offered to libraries on the use of data on the real behavior of the target audience of the library website to improve access to library resources and services, increase their relevance and improve information services.

Data are a critical utility asset. Collecting correct data on site leads to accurate information. Data, when gathered with foresight & properly formatted, are useful to both existing database and easily transferable to newer, more comprehensive historical outage data. However, when investigating data items options, the task, can be an arduous one, often requiring the efforts of entire committees. This paper firstly discusses the KEPCO's past 10 years of historical outage data which include meterological data, and also by several elements of the National Weather Service, failure rate, outage duration, and probability classification, etc. Then, these collected data are automatically stored in an Outage Data Management System (ODMS), which allows for easy access and display. ODMS has a straight-forward and easy-to-use interface. It lets you to navigate through modules very easily and allows insertion, deletion or editing of data. In particular, this will further provide the KEPCO that not only helps with probabilistic security assessment but also provides a platform for future development of Probability Estimation Program (PEP).

전통적인 센서 네트워크는 고가의 센서와 케이블로 연결되어 있어, 센싱 데이터를 수집할 때 유연성이 떨어지는 단점을 가지고 있다. WSN은 저가의 장비를 사용하고, 임무를 여러 노드에서 나누어서 수행하기 때문에 다각도에서 세밀한 데이터를 수집할 수 있다. 본 논문에서는 대한석탄공사의 작업현장에서 IEEE802.15.4 MAC을 이용하여, 채탄 작업환경을 그대로 적용한 채탄토폴로지를 구성하였다. 채탄 작업시에 작업 관리자의 이동성 지원을 위한 모델들을 제안하였고, 시뮬레이션을 수행하여 최적의 모델을 선정하였다. 본 논문의 결과는 대한석탄공사와 다른 광업소에서 WSN을 적용할 때 중요 자료로 사용할 수 있을 것이다.

This study analyzes the physiological changes that occur after free diving and studies peroxidants and antioxidants according to the recovery method. Accordingly, the purpose of this study is to provide proper rest methods after free diving and provide basic data for free diving research. Eight male college students recovered for 30 minutes after 20 free injections at a 5-meter diving site, 20 free injections after a week's car wash, and recovered for 30 minutes after collecting blood during recovery to analyze the effects of peroxidants and antioxidants. Comparison of changes in peroxidants and antioxidants in recovery methods after free-diving iterations showed that SOD tended to decrease immediately after free-diving, increasing MDA to 10 minutes after recovery, but no significant difference was found. The purpose of this study is to observe physiological changes according to the recovery method after free diving and to propose an appropriate recovery method after free diving. However, there was no significant difference in all the restoration methods, and 20 freediving was not high kinetic intensity for the subjects, which is believed to have resulted in the following results. Therefore, it was discussed that the repetitive diving strength should be higher to confirm a significant difference in the recovery method after free diving.
