The electroencephalogram generated by light stimulation in human body of dark adaption state was measured and analyzed in the cases that electromagnetic wave was put in and not put in, respectively. Shieldroom being able to interrupt the light and the electromagnetic wave of outer was constructed, and the experimental system being able to apply any light and any electromagnetic wave was designed. When the electromagnetic wave was applied to body or not, the variation characteristics of each component in the electroencephalogram were i3s follows. The 6 wave was increased and the $\alpha$ wave and the $\beta$ wave were decreased in the case that the electromagnetic wave was applied, and the variation range of the $\Theta$ wave was small. And the influence of electromagnetic wave on human body was that the appearance time of the $\beta$ wave was late, and it moaned that the time of visual recognition was delayed.

The aim of this study is to improve the fault decision ability of FRTU (Feeder remote terminal unit) in DAS (Distribution automation system). FRTU uses the FI (Fault indicator) algorithm based on fault current pickup and operation of the protection device. Even if the inrush current flows or the protection device is sensitive to the transient current, FRTU may indicate incorrect fault information. To address these problems, we propose an improved fault recognition algorithm that can be applied to FRTU. We will detect a specific wave that is indicative of a fault, and use this information to identify a fault wave. The specific wave-detection algorithm is based on the duration and periodicity of the voltage, current, and harmonic variations. In addition, we propose fault recognition algorithms using voltage factor variation analysis and DWT (Discrete wavelet transform). All the wave data used in this study were actual data stored in FRTU.

본 연구는 베트남 유학생을 대상으로 한류에 대한 인식을 조사하고 한류 인식이 치즈닭갈비 선호도에 어떠한 영향을 미치는지 치즈닭갈비 선호도가 높은 외국인의 경우 한식 이미지와 한식당 방문 의도에 긍정적인 영향을 보이는지 그리고 한류 인식과 치즈닭갈비 선호도 사이에 SNS가 매개역할을 하는지 확인 분석하여 한식 세계화, 한식 메뉴 개발 및 마케팅 활동에 도움이 되는 결과를 도출하고자 하였다. 분석결과 한류인식이 치즈닭갈비 선호도에 정(+)의 영향을 미친다는 가설은 채택되지 않았으며, 한류 인식은 SNS 영향을 통하여 한식선호도에 영향을 미치는 것으로 확인되었다. SNS 영향은 한류인식과 치즈닭갈비 선호도 간 매개역할을 하는 요인임을 확인하였다. 외국인의 경우 다양한 매체 중에 SNS 영향이 한류인식과 한식 간 중요한 역할을 하는 요인임이 확인 할 수있었다. 본 연구 결과를 바탕으로 한식 선호도 및 단일 메뉴 선호도에 영향을 미칠 만한 다양한 요인에 대한 연구와 한식 세계화가 가능한 한식에 대한 재조명이 필요하다고 생각된다.

In order to successfully exploit underwater resources, the first step would be a marine environmental research and exploration on the seafloor. Traditionally one sets up a long-term underwater experimental unit on the seafloor and retrieves the unit later after a certain period time. Essential to these applications is the reliable teleoperation and telemetering of the unit. This study presents ultrasonic-wave remote control system and an underwater sound recognition algorithm that can identify the sound signal without the influence of disturbances due to underwater environmental changes. The proposed method provides a means suitable for units which require low power dissipation and long-time underwater operation. We demonstrate its ability of securing stability and fast sound recognition through experimental methods.

In this paper, image processing technique that reduces video images of buoy motion to yield time series of image coordinates of buoy objects will be investigated. The buoy motion images are noisy due to time-varying brightness as well as non-uniform background illumination. The occurrence of boats, wakes, and wind-induced white caps interferes significantly in recognition of buoy objects. Thus, semi-automated procedures consisting of object recognition and image measurement aspects will be conducted. These offer more satisfactory results than a manual process. Spectral analysis shows that the image coordinates of buoy objects represent wave motion well, indicating its usefulness in the analysis of wave characteristics.

Condition monitoring technology is of great importance for the maintenance of complex machinery in view of its early monitoring of the abnormal condition and the protection against failure. Several methods have been used for the detection of failure of journal bearings, one of the main elements of mechanical system. The methods most frequently used are vibration and temperature monitoring, but these are unable to monitor the wear conditions exactly. In this study, an ultrasonic measument method, one of the non-destructive testing methods, was introduced as the monitoring technology. Furtermore a pattem recognition method was applied to analyze the ultrasonic signal. The monitoring system using the pattern recognition method is composed of digital signal processing units and uses Hamming net algorithm for the recognition of ultrasonic waves. From the journal bearing wear test, the occurrence of adhesive wear of the white metal in rubbing contact with the shaft was exactly detected by this system, and the wear status of the journal bearing was monitored by measuring the wear thickness.

This Paper Presents the method for detecting a partial discharge(PD) using an electromagnetic wave measured by an antenna. The various electromagnetic waves are measured in the laboratory and wavelet transform, which is provides a direct quantitative measure of spectral content in the time-frequency domain, are applied for identifying the property of electromagnetic waves. Also, the statistical method and self-organizing feature map(SOFM) are applied for the pattern recognition of electromagnetic waves. The proposed method is shown to be useful for detecting electromagnetic waves emitted for PD in test data.

This questionnaire study was conducted to investigate the levels of recognition and attitude for Korean traditional food among Japanese tourists. The aim was to provide basic data for making a detailed marketing direction alignment of globalization and commercialization of Korean traditional food. The results can be summarized as follows. The 'Korean wave(Hanliu)' was 'the number of known Korean star performers'(3.77 points), 'the number of watched Korean dramas'(3.67 points), 'the number of watched Korean movies'(3.44 points), 'the number of owned Korean singer's tapes or CDs'(3.04 points), 'the number of read books'(2.83 points), and 'the number of viewed cartoons'(2.49 points), in order. The high-intake frequency of Korean traditional foods was 'Bibimbap', 'Galbigui', 'Baechookimchi', 'Bulgogi', 'Kkakdugi', 'Tteokbokki', 'Japchae', 'Galbitang', 'fajeon', and 'Namullyu' in order. On the other hand, the intake frequency of 'Songpyeon', 'Inielmi', 'Sikhye' and 'Sujeonggwa' was very low. The most effective 'Hanliu' item for raising the recognition of Korean traditional food was 'the number of read books'. The most effective 'Hanliu' item for raising the experience of Korean cooking was 'the number of read books', followed by 'the number of watched Korean movies', 'the number of watched Korean dramas', and 'the number of viewed cartoons' in order. The most effective 'Hanliu' item for raising the intake frequency of Korean traditional food was' the number of watched Korean dramas', followed by 'the number of watched Korean movies' and 'the number of read books' in order.
