중국신화학에서 유가의 위상과 전용(轉用)

宋東盈(Song, Dong-young) 중국어문학연구회 2017 중국어문학논집 Vol.0 No.102

In the myth area, Confucianism had been considered irrelevant or harmful to development until the mid-20thcentury. However, Confucianism has been steadily summoned to the myth area with various values from late 20th century to today and it is considered that an indispensable close relationship exists. This conversion of thinking derived from Yuanke representing Chinese mythology and then its flow is being continued by a series of researchers focusing on Yeshusian. For right understanding of this, this paper would examine how Confucianism was excluded from the mythological area due to the anti-traditionalism when Chinese mythology was established in 20C, and how Confucianism was summoned again in mythology from late 20C to today. It would be examined what difference exists in the Confucian utilization by Yuanke and Yeshusian.

葉舒憲의 儒家神話論에 대한 비판적 고찰

宋東盈(Song, Dong-young) 중국어문학연구회 2016 중국어문학논집 Vol.0 No.96

In 2011, Ye Shuxian in charge of president of Chinese mythology claimed “Confucian mythologies” as a result of the mythology study of Origin of the Chinese civilization project. The point under the “Confucian mythologies” is that the mythology be found in Confucian ideas unlike existing theory that the most of Chinese mythology be found in Taoism not in Confucian ideas. The writer thinks Chinese extensive history distortion attempts such as the Northeast Project, Chinese ancient civilization project, and Liaohe civilization is hidden in the “Confucian mythologies” that Ye Shuxian claimed to reveal the Chinese origin who was a director of the mythology study Origin of the Chinese civilization project. He made a link with other elements of Chinese civilization research process, for example Hongsan culture or Jade Worship faith while actively utilizing Confucianism that forms a mainstream of the Chinese traditional idea, politics, society, and institution, and deep-rooted in Chinese people, and is emerging again today in order to solidify the “Origin of the Chinese civilization project” more.

A conventional type ballast for fluorescent lamp is replaced by an electronic ballast, because of its merit. Electronic ballast have characteristics of rapid start, reduction of energy consumption, stability and so on, but it has harmonic waves by switching in high frequency. This paper proposes a highly power factor investor circuit for fluorescent lamp ballast with two state capacitors. A full-wave rectifier used as a direct current power supply at fluorescent lamp ballast contains a lot of harmonic waves caused by inrush current. Inrush current is generated near the maximum input voltage, when smoothing capacitor is charged. This study proposes a new method to control inrush current by use of charging voltage at pre- state capacitor. From the simulation result, it is confirmed that the THD(Total Harmonic Distortion) is improved about 9.1[%] and the PF(Power Factor) is improved about 2.2[%] in comparison whit that of conventional ballast

In order to develop a LED luminaire for naval-submarines which can replace a conventional one with two-compact fluorescent lamp (CFL) of 18 W, we analyzed the electrical and optical performance of the conventional luminaire. A LED luminaire was fabricated as compact as possible based on the analyzed data. The weight of the prototype LED luminaire is 1.8 kg, reducing up to 58% of the conventional one. The use of LED package for the submarine luminaire could reduce the power consumption from 38 W to 14.5 W with the same optical performance. The reason is that the optical efficacy of the LED luminaire improved by 2.47 times as 61.9 lm/W, compared to 25.1 lm/W for the conventional one.

본 논문에서는 저전압 교류회로에서 과도이상전압에 대한 보호소자로 사용되는 산화아연형 바리스터의 뇌충격전류에 대한 영향에 대하여 기술하였다. 산화아연형 바리스터는 뇌충격전류에 의해 열화가 진행되며, 열화된 바리스터는 정상 운전전압에서도 열폭주에 도달하여 파괴되므로, 바리스터의 전기적 특성변화를 평가 하는 것은 대단히 중요하다. 바리스터를 가속열화시키기 위하여 국제규격 IEC 61000-4-5에 규정된 뇌충격전류를 적용하였으며, 1회의방전에 바리스터에는 약 12(J)의 에너지가 인가된다. 뇌충격전류의 인가에 따른 바리스터의 누설전류, 정격전압 등을 측정하였으며, 또한 바리스터에 뇌충격전류를 200회 인가 후 초기상태의 미세구조와 비교하였다. 실험결과로부터 바리스터는 뇌충격전류의 인가에 따라 누설전류는 증가하고 정격전압은 감소하는 경향을 나타내면서 전기적 성능이 저하됨을 확인하였다. This paper presents the effect of lightning impulse current on ZnO varistors(390[V], 6.5[kA]) used in low-voltage AC mains as a protective device against transient overvoltages. The electrical characteristics of ZnO varistors are deteriorated by overtime impulse current, and a deteriorated ZnO varistor is brought to a thermal runaway and finally destroyed even in normal operating voltage. Therefore, it is important to estimate the changes of the electrical characteristics of ZnO varistors. A lightning impulse current standardized in IEC 61000-4-5 is applied to the varistors to accelerate deterioration, and the energy applied to the varistor at each time is about 12 [J]. In the experiment, various parameters such as leakage current, reference voltage are measured with the number of applied impulse current. Also, micro-structure changes of the varistors after applying the lightning impulse current of 200 times are compared. The electrical characteristics of the varistors are degraded by overtime impulse current, showing increase in leakage current and decrease in reference voltage.

This paper describes a rotation-type field mill to measure the electric field intensity caused by thunderclouds on the ground level. The field mill developed is consisted of two isolated electrode vanes, a grounded stator and a rotor. To develop a high sensitive field mill, the principles and design rules of a rotation-type field mill are studied. Also, two types of calibration system, such as a cylindrical guard electrodes and a parallel-plate electrodes, are proposed to determine the sensitivity and frequency bandwidth of the field mill. From the calibration experiment, the frequency bandwidth and the sensitivity of the field mill are DC ~ 200 [Hz] and 0.267 [mV/V/m], respectively. Therefore, it can measure the electric field intensity from 73 [V/m] to 18.7 [㎸/m]. 본 논문은 뇌운의 접근에 따라 변화하는 대지전장 측정을 위하여 필드 밑을 이용한 대지전장 측정장치의 개발에 관하여 기술하였다. 필드 밀은 두 개의 절연된 전극으로 구성되며, 회전전극과 고정 전극이 있다. 고정도 필드 밀 개발을 위하여 회전형 필드 밀의 원리 및 설계기법에 관하여 연구하였으며, 교정실험장치로 원통형 가드전극계 및 평행평판 전극계의 두 가지 방법을 이용하여 주파수 대역 및 응답감도 특성을 조사하였다. 교정 실험결과로부터 주파수 대역 및 응답감도는 DC ~ 200(Hz), 0.267[mV/V/m]로 얻어졌으며 73[V/m] ~ 18.7[㎸/m] 범위의 대지전장 변화의 측정이 가능하다.

This paper describes the design and fabrication of a home-panel board for electromagnetic compatibility which can protect home-electric appliances from transient voltages and power line noise. The proposed panel board include a transient voltage blocking device and a EMI filter which consisted of varistors, capacitors, and bus line inductance.A performance test of the prototype panel board, blocking characteristics to transient voltages and reduction characteristics to power line noise, are carried out by using a combination surge generator standardized in IEC and a network analyzer.The results showed that the proposed panel board is satisfied with the surge immunity level of IEC 61000-4-5, and has an over 20[dB] noise reduction performance in ranges from 150[kHz]∼30[MHz].
