  • 본 논문에서는 멀티미디어 컨텐츠의 새로운 패러다임인 MPEG-21의 7가지 요소 중 하나인 이벤트 리포팅에 대한 정의와 필요성에 대해 알아보고 디지털 데이터 방송에서의 이벤트 리포팅 유즈 케이스 시나리오를 통해 이벤트리포팅 메시지들을 예시하고, 이의 전달을 위한 MPEG-21 이벤트 리포팅 구조를 정의하고자 한다. MPEG-21에서는 멀티미디어 프레임워크 내의 디지털 아이템과 관련되어 발생하는 모든 상호 작용을 이벤트라 통칭하구 이를 사용자에게 보고함으로써 신뢰성 있는 전달, 사용자의 프라이버시를 담고 있는 개인 데이터와 기호의 관리, 그리고 저작권 보호관리 등을 위한 목적으로 활용하고자 한다. 본 논문에서는 MPEG-21의 이벤트에 대한 표준적인 측정방법 및 인터페이스를 제공하기 위한 이벤트 리포팅에 대한 정의 및 필요성에 대해 알아보고, 또한 MPEG-21의 이벤트 리포팅에 대한 표준화 활동 동향에 대해 소개하고자 한다.

  • Angiogenesis is an essential event in a variety of physiological and pathological processes. Therefore, effective inhibition of this event is a promising strategy for treating angiogenesis-related diseases, including cancer. The current study investigated two unique bafilomycin-type macrolide inhibitors of angiogenesls, PC-766B' (1) and PC-766B (2). The strain RK97-56 which produced the inhibitors was identified as Nocardia sp. by chemotaxonomic analyses, and the purification of the inhibitors was guided by their anti-angiogenic activities. PC-766B' (1) and PC-766B (2) exhibited potent inhibitory activities towards endothelial cell migration stimulated by the vascular endothelial growth factor (VEGF).

  • 소셜 네트워크 서비스의 사용량이 증가함에 따라 오프라인에서 발생한 이벤트 정보가 더욱 빠르게 확산되고 있다. 이에 따라 소셜 데이터를 분석하여 이벤트를 검출하기 위한 연구들이 진행되고 있다. 본 논문에서는 소셜 네트워크 환경에서 사용자 관심도를 고려한 그래프 기반 이벤트 검출 기법을 제안한다. 제안하는 기법은 사용자들이 게시한 글을 분석하여 키워드 그래프를 구축한다. 사용자의 소셜 행위로부터 관심도를 계산하고 관심도의 변화를 고려하여 이벤트 판별에 이용한다. 따라서 의미 없이 반복 게시되어 이벤트로 검출된 결과를 제거하고 결과의 신뢰성을 향상시킬 수 있다. 제안하는 이벤트 검출 기법의 우수성을 입증하기 위해 다양한 성능평가를 수행한다.

  • 온라인 쇼핑 시장이 IT 기술발전과 더불어 급속히 성장하게 되면서, 다양한 형태와 함께 온라인 쇼핑들 간의 치열한 경쟁이 심화되고 있다. 이에 따라 온 오프라인에서 차별화된 특징이 경쟁력을 도모할 수 있게 되었으며, 젊은 계층인 연인들을 마케팅 대상으로 하는 커플 이벤트 기획이 필요하게 되었다. 본 연구에서는 커플 및 젊은 구매계층들을 마케팅 대상으로 하며, 매출 향상을 목적으로 기획 및 구현된 사이트 개발을 목표로 하고 있다. 이를 위해서 기존 상업 사이트에 대한 이벤트 기획들에 대한 분석을 기반으로, 커플 생일을 마케팅 전략 및 다양한 기념 이벤트 및 고객들이 사이트를 방문하였을 때 이벤트가 한층 돋보이도록 마케팅 기획과 정보 배치를 중심으로 사이트를 구축하였다. 이를 통해 일부 고객층 대상으로 이벤트 효과 증대를 통한 매출 증대를 도모할 수 있을 것으로 기대된다.

  • To find out more efficient ways of implementing health promotion programs and to determine the factors affecting the results of various interventions, we reviewed 73 articles un the effectiveness of health promotion programs. These include the papers on the smoking, alcohol, drug abuse, nutrition(obesity) and stress management etc. Specific interventions evaluated in this review are education based on the lecture or video shows, health-related event activities, modifications of policy or the environment, health risk appraisal etc. By using KIHASA Line of Korea Institute of Health and Social Affairs, National Congress Library Database MEDLINE, we identified 201 articles published from 1980 to Jun. 1979 and finally selected 73 papers which contain the implementation process, and result of each program. The factors used in the analysis of the programs are (1) characteristics of participants (2) interventions evaluated (3) research design (4) length of programs and evacuation point (7) outcome indices (6) effect of program evaluated by each author. The study results did not prove positive effect of education based on lectures or video shows etc. Rather, it was suggested that lecture-based education has negative effect on the result. Event activity such as contest or health festivals has positive effect, and policy change or environmental change is closely related to the event activity. Also, the result shows that the overall effect of programs fur the students is less than that of the programs for the others. The programs conducted over, 1-year are mere likely to have positive outcomes than shorter ones. And, the outcomes of the programs with controlled research design such as experimental or quasi-experimental study tend to be evaluated inferiorly to those with non-experimental design.

  • Spacecraft mission planning functions including event prediction, mission scheduling, command planning, and ground track display have been developed for the KOMPSAT-2 mission operations. Integrated event prediction functions including satellite orbital events, user requested imaging events, and satellite operational events have been implemented. Mission scheduling functions have been realized to detect the mission conflicts considering the user specified constraints and resources, A conflict free mission scheduling result is mapped into the spacecraft command sequences in the command planning functions. The command sequences are directly linked to the spacecraft operations using eXtensible Markup Language(XML) for command transmission. Ground track display shows the satellite ground trace and mission activities on a digitized world map with zoom capability.

  • Forestry and agricultural land uses constitute 85% of Korea and these land uses are typically mixed in many watersheds. Biological Oxygen Demand (BOD) concentration is a primary factor for managing water qualities of the water resources in Korea. BOD loadings from diffuse sources, however, not well monitored yet. This study aims to assess BOD loadings from diffuse sources and their affecting factors to conserve quality of water resources. Event Mean Concentration (EMC) of BOD was calculated based on the monitoring data of forty rainfall events at four agricultural-forestry watersheds. Exceedence cumulative probability of BOD EMCs were plotted to show agricultural activities in a watershed impacts on the magnitude of EMCs. Prediction equation for each rainfall event was proposed to estimate BOD EMCs: $EMC_{BOD}(mg/L)=EXP(0.413+0.0000001157{\times}$(discharged runoff volume in $m^3$)+0.018${\times}$(ratio of agricultural land use to total watershed area).

  • Although Firms have been increasing their information security significantly to handle increased security risks, the effects of information security were not well understood. This study aims to investigate the market value of information security by employing the event study methodology. Our research also explores how market responses vary depending on the type of information security announcements. We collected 177 firm-level information security announcements between 2001 and 2017 in South Korea. For all samples, our results indicate that the stock market positively reacts to information security announcements. We also conducted subsample analysis and found that while information security certification announcement has a positive impact on the stock market, information security activities (e.g. award, information security system) announcement had no impact on the stock market. Our study adopted a novel approach (i.e. event study) for investigating the effects of information security and found that information security investment positively affects firm value. Our results allow managers to measure the effects of information security investment and help them make right decisions on information security investment.

  • EDS is a typical convergence service performing convergence between functions owned by multiple SPs. EDS provides users with the relevant information and the communication by the various personal conditional environment. An alternative terminology for events for net- work related applications is 'triggers'-these are assumed to be included in the present description. Events could be defined as any activities which occur within a service avail ability, signals. Events can be managed, for example, as part of a context-aware application. EDS carry out a procedure for processing user's requested information about mobil network-based entities, such as the combination with various applications, such as a LBS (Location Based Service) and area information. In AS (Application Service) network environments, the user has his customized EDS in the network, the EDS automatically connects the appropriate Terminals consistent with a user profile. EDS can also send the collected information to other requesting users by way of event information and using the procedures of combination with other services. The user can record/retrieve the user-related information to from the information base through EDS.

  • When cyber attacks are discovered in nuclear facilities, licensees are required to notify regulatory organizations for quick action. This also helps regulatory organizations to strengthen regulatory capabilities for cyber security. Currently the U.S. issued the final draft rule for Cyber Security Event Notifications. Domestic regulatory activities being at an early stage for cyber security need to implement law for Cyber Security Event Notifications. Since the current laws are focused on the aspect of safety, they are in need of more specific laws for cyber security.
