The purpose of this study was to examine consumers' ability to distinguish advertorial and editorial about consumer information. The data were collected between June, 28 and July, 2 in 2010 through the Internet surveys. Total of 603 respondents were included in the analysis. The findings are follows as: First, consumers showed better ability to discern advertorial than ability to discern editorial. It implied that editorials could be considered as advertorial rather than advertorial could be considered as editorials. Second, it seems likely that rather than executional cues such as format and source information, the types of products/services were used as source cues among consumers. Third, consumers tend to prefer 'consumer information', 'advertorial' and 'advertisement' among 10 given advertising labels. In Conclusion, to prevent misleading potentials of advertorial and editorials, standardized advertising label should be used and notify consumers of advertising label.

At this study, we are developing a possible control system through remote monitoring for fire protection in various chemical factory facilities. It's possible to do real time confirmation of a normal operation presence of the various equipment installed in a chemical factory through the internet network at a fire fighting head office, an area fire department and a chemical factory situation room using this remote monitoring control system. When occurring, abnormal operation is the remote monitoring control system, which can check this immediately and notify the situation room administrator. After it was tested using developed remote monitoring control system, the remote monitoring for which the internet network was used confirmed possible.

디지털방송의 주요 특징은 고품질, 데이터방송, 다채널로 요약할 수 있다. 다채널화는 현재보다 채널수, 프로그램수의 급격한 증가로 이어지며 채널수 프로그램수의 증가는 시청자가 지금보다 원하는 프로그램을 찾는데 보다 많은 시간이 소요됨을 의미한다. 디지털 방송에서는 시청자의 프로그램 탐색을 돕는 전자프로그램 가이드(EPG : Electric Program Guide) 서비스를 제공하고 있으나 현재 EPG는 기존의 신문에서 제공하는 채널별 프로그램 가이드와 크게 기능이 다르지 않다. 이에 따라 최근 EPG는 주제별, 시간대별 방송프로그램 검색 외에 Agent의 개념을 도입하여 개인의 취향을 분석하는 EPG를 개인화에 대한 연구가 이루어 지고 있으며 더 나아가 정보를 자동으로 공지하는 방법에 대한 연구도 요구되어 진다. 본 연구에서는 사용자 취향에 적합한 프로그램 정보가 취득 되는 대로 별도 조작 없이 공지될 수 있는 ${\ulcorner}$자동공지 기반의 AP-EPG${\lrcorner}$ 에 대하여 제안하고자 한다.

핸드오버가 발생하는 NEMO(NEtwork MObility) 환경에서 주요 이슈 중 하나는 MR(Mobile Router)이 핸드오버 하는 동안에도 NEMO 네트워크 내의 MNN(Mobile Network Node)들에게 지속적인 QoS(Quailty of Service)를 보장해주는 것이다. 이를 위해 MR의 등록과 자원예약 프로세스가 완료되기까지의 지연시간을 최소화하는 것이 중요하다. 또한 MR이 핸드오버 하는 동안 네트워크상에 전달되고 있는 데이터 패킷들의 손실을 최소화해야 한다. 이에, 본 논문에서는 NEMO 네트워크에서의 자원예약 트리거와 버퍼링 방안을 제안한다. 제안하는 방안에서는 MR이 새로운 경로와 이전 경로가 만나는 지점의 노드인 CRN(CRossover Node)에게 NOTIFY 메시지를 보내 새로운 경로 상에 자원예약 셋업이 빨리 시작하도록 트리거 하였고, 자원예약이 수행되고 있는 동안 인터넷상에 전송중인 데이터 패킷들의 손실을 줄이기 위해 CRN에서 버퍼링하도록 하였다.

This study involves a Common Cause Failure (CCF) problem on the ultra-high reliability required system development such as war game operations, nuclear power control, air traffic control, space shuttle missions, and large scale network communication system. The system situation problems are defined according to CCF, reliability and system fault identifications for the development cast verifications in the multi-version redundant software system. Then, CCF analysis of redundant system, system principles and statistical dependence are also described. This validation oh the CCF in the human software interaction system will notify software engineers to conceive what really is CCF contribution factor, not only the internal but the external ones.

Recently, Biometrics is being magnified than ID or password about user authentication. However, unlike a PIN, password, and personal information there is no way to modify the exposure if it is exposed and used illegally. As FIDO(Fast IDentity Online) than existing server storing method, It stores a user's biometric information to the user device. And the user device authentication using the user's biometric information, the user equipment has been used a method to notify only the authentication result to the server FIDO. However, FIDO has no mutual authentication between the user device and the FIDO server. We use a Certificate Authority in order to mutually authenticate the user and the FIDO server. Thereby, we propose a more reliable method and compared this paper with existed methods about security analysis.

The AQM (Active Queue Management) starts dropping packets earlier to notify traffic sources about the incipient stage of congestion. The AQM improves fairness between response flow (like TCP) and non-response flow (like UDP), and it can provide high throughput and link efficiency. In this paper, we suggest the QVARED (Queue Variation Adaptive RED) algorithm to respond to bursty traffic more actively. It is possible to provide more smoothness of average queue length and the maximum packet drop probability compared to RED and ARED (Adaptive RED). Therefore, it is highly adaptable to new congestion condition. Our simulation results show that the drop rate of QVARED is decreased by 80% and 40% compare to those of RED and ARED, respectively. This results in shorter end-to-end delay by decreasing the number of retransmitted packets. Also, the QVARED reduces a bias effect over 18% than that of drop-tail method; therefore packets are transmitted stably in the bursty traffic condition.

Kindergarten children are engaged in the age of physical immaturity as well as the rapid growth. The indoor air contaminants that are proved to affect even the full grown adults are obvious to have no little influence to immature small children in a growth period. In May 2004, for the multi purpose facilities and newly constructed apartments, the Ministry of Environment announced "Indoor Air Quality Control Law for the Multi Purpose Facility," which made the interests to be focused in the urgent understanding of current condition and preparation of measures about the indoor air pollution. In Dec 2005, the law was revised to obligatorily notify the amount of Formaldehyde and Volatile Organic Compounds in the case of newly constructed apartments with more than 100 houses. However, since the kindergarten takes none of the classifications, even the current condition is not grasped although it is directly connected to the health of growing children. Therefore, the study aims to analyze indoor air pollution of one selected kindergarten in Incheon city.

This paper is aimed to develop the circuit of a coil-type oil sensor packaged to the automotive engine oil monitoring the deterioration in the driving condition and let a driver notify the optimized time for the exchange of engine oil. By applying the principle which the deterioration of automotive engine oil can be expressed to the dielectric constant, the capacitance bridge circuit and the integrator circuit are designed and packaged to a coil-typed engine oil. In this study. the range of operating temperature of engine oil is experimentally recommended within 55$^{\circ}C$ for the stability of a sensor designed. It is concluded that the characteristics of output voltage converted from the dielectric constant are linearly distributed.
