해외에 진출한 국내기업의 소송 사례가 증가하면서 기업들의 전자증거개시제도의 대응에 대한 요구가 증가하고 있다. 영미법에서 유래된 제도인 전자증거개시제도는 절차 진행과정에서 여러 곳에 산재해 있는 전자적 정보들을 중 제한된 시간 내에 소송과 관련된 전자적 정보들을 찾아 증거자료로 검토하여 제출하는 제도이다. 이는 하루에도 수많은 전자기록이 생산되는 국내기업들의 기록관리가 잘 이루어지지 않고 있는 현실에서 제한된 시간 이내에 증거자료를 추리고 검토하여 제출하는 것은 쉽지 않은 일이다. 검토대상을 줄이고 검토과정을 효율적으로 진행하는 것은 소송에서 승소를 위한 가장 중요한 과제 중 하나이다. Predictive Coding은 전자증거개시 검토 과정에서 사용되는 도구로써 기계학습을 이용하여 기업들이 보유하고 있는 전자적 정보들의 검토를 도와주는 도구이다. Predictive Coding이 기존의 검색도구보다 효율성이 높고 잠재적으로 소송과 관련된 전자적 정보를 추려내는데 강점이 있다고 판단된다. 기업의 효율적인 검색도구의 선택과 지속적인 기록관리를 통해 검토비용의 시간적, 비용적 절감을 꾀할 수 있을 것으로 예상된다. 따라서 기업은 전자증거개시 제도에 대응하기 위해서 시간과 비용적 측면을 고려한 전문적인 Predictive Coding 솔루션의 도입과 기업 기록관리를 통해 가장 효과적인 방법을 모색해야 할 것이다.

PROFIBUS is an open industrial communication network for a wide range of application in manufacturing automation and process control systems. PROFIBUS-DP(Decentralized Peripherals) are mainly used to connect smart automation devices via a fast serial link. PROFIBUS-DP adopts master/slave mechanism for communication service. In this paper, we present an implementation method of the protocol stacks for the master station of PROFIBUS-DP.

본 논문에서는 실시간으로 MIDI (Musical Instrument Digital Interface)를 이용하여 음악을 연주학 수 있는 전자음악장갑 (Electronic Music Glove, EMG) 시스템을 소개한다. 마이크로 컨트롤러를 통해 장갑으로부터 입력받은 아날로그 신호를 분석하고, 이 신호를 MIDI 메시지로 변환한 후, 컴퓨터에 내장된 사운드카드의 MIDI 음원을 이용하여 스피커로 음악을 재생한다. 컴퓨터의 직렬 포트를 통해 손가락에 부탁된 센서들과 풋 스위치의 상태를 입력받아 C++ 언어로 작성한 프로그램에서 MIDI 메시지로 변환한다. EMG 시스템은 음표의 옥타브와 음표의 길이, 그리고 코러스나 잔향, 리듬 그리고 볼륨과 같은 다양한 음악적 효과를 MIDI를 이용해 제어할 수 있다.

This paper focused on developing and empirically testing an EAM(Electronic-Store Acceptance Model), By basing upon Davis' TAM(Technology Acceptance Model) and reflecting the characteristics of EC(Electronic Commerce), the EAM was proposed. This EAM could be regarded as a revised and extended TAM in the EC area. The theoretical rationale of this model was as following: 1) Though Davis' TAM was proposed a powerful tool to explain and predict usage of Information Technology, nowadays, TAM variables(perceived usefulness and ease of use) are posited as key drivers of e-commerce acceptance. 2) In the e-commerce and e-business studies, trust has been emerging as a potentially important antecedent of IT adoption. A famous internet book store was chosen to empirically test the EAM. In order to evaluate reliability and validity of instrument, and validate the research model, SEM(Structured equation model) analysis was conducted. The results showed that perceived usefulness and trust significantly influenced e-Store Acceptance but perceived ease of use did not have significant influence on e-Store Acceptance.

In this paper, we have checked a method of performance evaluation for electronic pedal, which is a core technology of HBD for detecting the axle temperature of high-speed train. As it is practically impossible to conduct train speed test of 500 km/h, we utilize a high speed rotor for evaluating high speed performance of the electronic pedal instead. According to this method, we found that the measurement results by the velocity measuring instrument is similar with the ones from this research through the high speed rotor. In conclusion, it will be possible to conduct reliability evaluation for high speed performance for Beacon, Balise and RFID, which are utilized for transmitting vital information of train control systems through using the rotor.

The Electronic Commerce is expected as one of the most prospective industries in the 21th century. This research developed a survey and analysis is based on the results of the service quality model and previous research of the service quality in MIS. Service quality, one instrument developed by the marketing area, is provided as a possible measure of internet shopping mall. Service quality measure five service dimensions of tangible, reliability, responsiveness, assurance and empathy. The main purposes of this study are to develop an exploratory model based on service quality that can explain the factors of customer's perceived service quality and investigate how these factors are related to consumer satisfaction. This study also focus on relationships among service quality, consumer satisfaction, and purchase intentions. The results of this survey are summarized as follows: (1) Reliability and responsiveness of internet shopping mall are evaluated as very important factors, (2) Service quality is an antecedent of consumer satisfaction, (3) Consumer satisfaction has a significant effect on purchase intentions.

Nd:YAG($\lambda$=266 nm, pulse) laser beam was irradiated on the PDMS surface to improve its chemical reaction, wettability, adhesive property. The various surface modification methods of PDMS were already studied using oxygen plasma, ozone and corona discharge. The surface modification using laser has the advantage of the simple experiment that only directly irradiated laser beam on the PDMS surface in the air. After the laser treatment, the PDMS surface was investigated using a contact angle measuring instrument. The contact angle was decreased with a increase of the surface oxygen content. In conclusion, the wettability of PDMS surface was improved by the laser treatment without changing of its bulk characteristics.

Light-emitting diode(LEDs), diode arrays, and phosphor display panels are finding increased use in a variety of commercial applications. Present and anticipated application of these devices include solid state indicator(e.g., digital clocks, meter readout) and display systems(e.g., instrument panels, TV display), the application being determined by the light -output capability and size availability(cost) of the particular device. In this work, Phosphor based on ZnS:Cu are used. Relation by luminance with the thickness of insulating layer and phosphor layer are discussed. Increased thickness of insulating layer are stable on voltage to 300V. By considering thickness and voltage, optimal structure and thickness are investigated. Also in order to maximize even surface emission, various sieving process are introduced. Very similar phosphor particle size is selected. Luminance by various wave intensity is also investigated. 150cd/m$^2$ luminance are investigated in stable voltage and frequency.

Solid insulation exposed to voltage is degraded by electrical tree process. And the degradation of the insulation is accelerated by voltage application. For this experimental, specimen of electrical tree model is made by XLPE (cross-linked polyethylene). And the size of the specimen is 7*5*7 $mm^3$. Distance of needle and plane is 2 mm. Voltages applied for acceleration test are 12 kV to 15 kV. And distribution characteristic of degraded stage is studied too. As a PD detecting and data process, discharge data acquire from PD detecting system (Biddle instrument). The system presents statistical distribution as phase resolved. Moreover the processing time of electrical tree is recorded to know the speed of degradation according to voltage.
