The interactive advertisement is already on satellite and cable broadcasting hereafter the introduction of this system is concerned on terrestrial programs. This study is to research the effectiveness of interactive TV advertising focusing on factors of involvement and interaction. Study started for the effect measurement of interactive television advertisement. Interactive television advertisement has different concept than existing television advertisement. Thus, the effect also needs to examine in other methods. Study is mainly focusing on the characteristics of interactive and the experiments, which was based on existing data, for measurement of effect. In the experiments, the characteristics were categorized in a search time, a number of searched pages about interactive television advertisement. The research finds that the involvement of the audience increases when the interaction of advertising attitude, brand attitude, and purchase intentions also increases. And so, a successful interactive TV advertisement results in longer searching hours and greater it visits by the audience when the interaction factors are considered and increased. By study of consumer's characteristics and behavior, a new method of the effect measurement for interactive television advertisement is provided. The new method includes not only existing measurement elements of television advertisement which are attitude on advertising and brand, and customers' purpose, but also the features of interactive television advertisement, which are search time, a number of searched pages. Recently added features provides data of the effect on high/low groups and it contributes to the process of interactive television advertisement. Study on interactive television advertisement will be helpful to plan an effective strategy by suggesting the theoretical evidence of its effect.

In this paper harmonic diagnose tool is described for electric evaluate the power quality at industrial power systems is described both simulation and experimental testing during various operation conditions. PTW (Power Tools for Windows) and harmonic measuring instrument are organized around personal computer and/or instrumentation study environments interconnected via RS-232. Unknown zero sequence impedance data of cable is calculated by the modified T&D and BICC method. IEEE standard is also used to estimate the transformer input data. the proposed system provides a flexible and effective environment to diagnose the power quality at industrial distribution systems by utilizing simulations and actual field data.

The purpose of this study is to secure the basis for judgment on the cause of an accident by analyzing the melting characteristics of a blade type fuse used for vehicles due to overload. In order to increase the reliability of the test, it was conducted by connecting the electrical system with conditions similar to those of an actual vehicle to apply the load. Carbonization pattern experiment of fuse by outside flame applied Korean Standard (KS). The fuse melted by the overcurrent showed a smooth cross-section while the test terminals, clear plastic body, etc., burnt out by the external flame was badly deformed. When 185% of the rated current (27.8A) was applied to a cable of 15A rated current onto which an over-capacity fuse (20A) was installed, the fuse melting time was 217 seconds. In addition, when a load current of 28.8[A] (139%) was applied, the fuse's test terminal and terminal blade were not burnt out although foam was observed on some parts of the plastic body. When a load capacity of 28.2[A] (141%) was applied to a cable of 15A rated current onto which an over-capacity fuse (30A) was installed, the fuse melting time was approximately 10 seconds. When a load current of 35.8[A] (119%) was applied, the fuse's test terminal and terminal blade were not burnt out, although some parts of the plastic body was swelled. However, it was observed that the switch terminal melted if approximately six minutes lapsed under such conditions. When a load capacity of 39.4[A] (131%) was applied to a cable of 15A rated current onto which an over-capacity fuse (30A) was installed, the fuse melted in approximately 69 seconds, and the test terminal and terminal blade were not burnt.

산업이 발달함에 따라 전기는 우리 일상생활에 있어 없어서는 안 될 중요한 요소이나, 전기는 시각적인 흐름을 볼 수가 없어 전기설비나 전기용품 사용중에 발생할 수 전기사고에 대해서 사전에 사고를 감지하고 예측하기 어려워 사고 위험성에 대하여 무방비 상태가 되나, 전력 사용량, 전기 위험도 분석 등에 대한 기술은 그에 미치지 못하고 있다. 이에 전기 사용 상태에 대한 분석이 가능하기 위해서는 분전반내부에 분석 회로장착이 필요하며, 전류 분석을 위해서는 전류센서(CT)가 구성되어 져야 하고, 이 전류신호는 data cable을 통하여 분석보드로 전송 되어져야 한다. 이는 수배전반 내부에 전력 케이블과의 접촉 문제, 결선 의 어려움 등이 있어 이를 해결 하고자 통신기능을 갖는 센서 내장형 차단기를 개발하고자 한다.

산업설비 중, 전력케이블은 설치 이후 적게는 수년에서 많게는 수십년에 걸쳐 진단없이 계속 사용 중에 있다. 인입케이블 경우, 한국전기안전공사에서 주기적으로 사업장 정기검사 시에만 DC내전압 시험을 실시하고 있으며 그 외에는 장시간 사용에도 불구하고 상태점검을 정확히 못 하고 있다. 본 연구에서는, DC내전압 시험 대신 현장에 적용되고 있는 VLF(Very Low Frequency) 진단방법에 대하여 수도사업장(취수장, 정수장 등)에서 사용 시, 진단방법 및 결과에 대한 신뢰성을 고찰하였다.

This study examines the concept of public interests in pay TV industry and analyzed the regulatory framework of the industry. The concept of public interests such as diversity, localism and quality which are mainly discussed in the context of over the air broadcasting extends to universal access, fair competition and consumer protection as pay TV industry grows. However, there is a lack of concrete implementation of public interests in regulatory framework and coordination of public and industrial interests was not accomplished. Major policy that regulates the pay TV industry carries out without big picture. Policy implementation without long term plan results in hierarchical regulation model and it produced consistency problem. In the process of implementing policy in pay TV industry public interests and industrial interests discussion is mixed and sometimes it played exaggerated role.

Due to current interest in creation of urban space and urban landscape, more emphasis has been placed on underground space development. With increasing number of underground power cables and its importance, a study of backfill materials for pipe is now imperative. Backfill materials require outstanding thermal characteristics since breakdown of cable insulation can be caused if heat generated from transmission of underground power cables had not been effectively discharged through backfill materials. Also, coal ash, which are industrial by-products, is being produced in high volume every year. Among them, ponded ash (PA) is not recycled and instead, mostly buried. Therefore in this study, thermal conductivity test based on mixture ratio (PA, ponded ash : FA, fly ash) was performed to evaluate the thermal conductivity characteristics of CLSM (controlled low strength materials) with coal ash. The results indicate that the mixture ratio (PA, ponded ash : FA, fly ash) of 80:20, water contents of 28~30%, and cement contents of 7-11% showed the highest conductivity at 0.796~0.884W/mK and thus, considered optimal in terms of recycling ponded ash (PA) as well as for maximizing utilization as backfill materials for pipe in underground.

The Measurement of risk parameter in city-gas equipments have been measured and confirmed by human, and evolved into remote monitoring system using wireless communication. Furthermore, domestic and international industry increase the efficiency of management, which can develop remote monitoring and control system using wireless communication. However, Those wireless system might be decrease the efficiency and ease because of connecting PDA and lap-top using wire-cable when data have checked immediately from outside. This paper is able to improve efficiency of safety management on city-gas equipments by developing mobile city-gas safety management system on AR.
