Structural Health Monitoring (SHM), particularly remote monitoring, is an emerging field with great potential to help infrastructure owners obtain more and up-to-date knowledge of their structures. The methodology could provide supplemental information to guide the frequency and extent of visual inspections, and the possible need for maintenance. The instrumentation for a SHM system needs to be developed with longevity and the objectives for the system in mind. Sensors need to be selected for reliability and durability, sited where they provide the maximum information for the objectives, and where they can be accessed and replaced should the need arise over the monitoring period. With the rapid changes now occurring with sensors and software, flexibility needs to be in place to allow the system to be upgraded over time. Damage detection needs to be considered in terms of the type of damage that needs to be detected, informing maintenance requirements, and how detection can be achieved. Current vibration analysis techniques appear not yet to have achieved the necessary sensitivity for that purpose. Societal factors will influence the design of a SHM system in terms of the sophistication of the instrumentation and methodology employed.

정보시스템 구축 프로젝트의 복잡성과 규모가 점차 커지면서, 프로젝트가 실패하는 경우가 발생한다. 프로젝트의 실패의 원인을 분석해보면 사용자의 프로젝트 이해 부족, 불명확한 요구사항 및 요구사항변경 등으로 소프트웨어 개발 생명주기 중 요구사항 분석 단계에서 대부분의 원인을 찾을 수 있다. 본 논문은 소프트웨어 개발 프로젝트에서 요구분석을 통해 도출된 기능과 변경요구 기능간의 추적 등 개발 생명주기 전체 기간 동안 지속적인 요구사항 변경 관리가 가능하게 하는 도구를 설계하였다. 그리고 프로젝트 관련자들 사이에서 충분한 합의와 협의를 통해 공통의 이해를 구축하는 효과적인 의사소통을 지원하는데 필요한 기능에 대해 논의한다.

최근 개인정보에 대한 유출과 침해행위가 급증하면서 악의적인 목적의 피해사례가 급증하고 있다. 대부분의 사용자가 윈도우즈 운영체제를 사용하고 있으며, 최근 Windows 7 운영체제가 발표되면서 Windows 7 OS 환경에서의 침해대응 기법에 대한 연구가 필요하다. 현재까지 개발된 침해사고 대응 기법은 대부분 Windows XP 또는 Windows Vista를 중심으로 구현되어 있다. 윈도우즈 운영체제에서 시스템 침해사고를 효율적으로 분석하기 위해서는 시스템에서 생성되는 이벤트 정보의 시간정보 및 보안 위협 가중치 정보를 중심으로 이를 시각적으로 분석할 필요가 있다. 따라서 본 논문에서는 최근 발표된 Windows 7 운영체제에서 생성되는 시스템 이벤트 정보에 대해 시각적으로 분석하고 이를 통해 시스템 침해사고를 분석할 수 있는 시스템을 설계 및 구현하였다. 본 논문에서 개발된 시스템을 이용할 경우 보다 효율적인 침해사고 분석이 가능할 것으로 예상된다.

A great deal needs to be learned about why and how users participate and consume information on various online sites. The design of socio-technical systems especially for promoting engagement in terms of maximum user participation is both a theoretical and real-world challenge that researchers strive to understand. At present, most of the research on the motives of Internet video users' behavior focuses on the user's "viewing motivation" and "sharing motivation", and lacks the analysis of the factors affecting users' "subscription motivation". This study will attempt to compensate for this gap. Based on the YouTube platform, we take Chinese video users as the research object and uses the "Censydiam user motivation analysis model" to make assumptions about user subscription motivation from the two levels of social needs and personal needs, using regression analysis. Validate the hypothesis and get the influencing factors that may be available in the user's subscription motivation based on the assumptions. Built on survey data from 215 respondents, the study found that Enjoyment, Vitality, Power, and Conviviality are four factors that influence user motivation.

This paper discusses the practical improvements for state government promotion programs to strengthen export competitiveness of small and medium trade business in the province to meet the needs of e-trade. This paper, first of all, describes how the problem on this subject relates to the existing literatures. It provides theoretical background about what programs mainly influence the export competitiveness of the province's small and medium business. Based upon the above results, the questionnaire for the analysis was grounded. The approach methodology is IP(Importance-Performance) analysis of satisfaction. The analysis collected the relations between the implementation and the satisfaction of 159 firms on the export promotion programs provided by its associated organizations. The I-P analysis results also reported that the organizations provided with the programs were listed in highly order of satisfaction as follows; KOTRA, Small and Medium Business Administration, Small Business Corporation, Gyeongbuk Internet Trade Center. Even though limitations of this paper exist, it can find provide the frames of ideal export promotion programs to meet the needs of a new era of trade.

In this study, elementary school teachers' needs for the website providing science instructional materials were examined. The participants were 151 elementary school teachers. The test for needs analysis consisted of fifty-three Likert-type items; 24 items for the content of website category and 29 items for the design of website category. Variables about participants' characteristics such as teaching career, the capability of using computers, and the frequencies of searching websites in obtaining science instructional materials were also examined. The results indicated that teachers' needs for the content of website category were significantly higher than those for the design of website category. Teachers' needs were relatively higher in the items concerning flawless materials, consistency of materials with science curriculum and/or learning objectives, information about target grade and/or related topics, free website, and the materials capable of immediate use in the content of website category. The items concerning the stability of website, the accuracy of links, providing easy and reliable searching methods, easy and fast downloading, and providing list of loaded materials showed relatively higher needs in the design of website category. In several items, teachers' needs were also changed with their individual characteristics.

Information & Communication Technology(ICT), called ubiquitous computing, changes our environment in many ways. It also acts on educational environment in concert with new pedagogy. Korean Government gives an efforts to set up the u-School as the educational environment supported by ICT. This study aims to find efficient uses of ICT to cope with the changing education environment and emerging needs of users. The survey research follows the pilot study on the model of future school. The students and teachers in six schools located in Busan answered the questionnaire and 752 individuals were analyzed by the statistical method including frequencies, crosstabs, ANOVA, and factor analysis. The conclusions are as follows: (1) Highly demanded were the u-School facilities to provide pleasant environment as the teachers and students have to spend most of time in classroom, or school premises. In addition, the infrastructures were so desperately required that students are able to control their textbooks and belongings, and efficiently utilize a variety of data. (2) The classroom volume should be planned a bit smaller than the current number of students so that teachers are relieved from the burden of too many student. The needs of students to interact with more students can be bolstered by utilization of ICT. (3) The respondents feel the high needs of computer for student, electronic blackboard, electronic lecture desk, microphone and computer for teacher as the teaching and learning facilities. This showed high needs for teaching and learning facilities enabling the active and individual learning through the use of ICT at education environment. In conclusion, the study proposes the fundamental data to combine u-School elements proper to the current learning and school environment, from the analysis on the use of school facilities, with the subjects, the users of education environment.
