This paper aims to investigate the cultural conflicts and characteristics of anti-Korean Wave discourse taken placed among Southeast Asian countries. To do this, it takes Vietnam and Indonesia as the study cases, which have been showing a trend of anti-Korean Wave discourse as well as high popularity of Hallyu. As research methods, the paper analyzes both on-line discourses of anti-Korean Wave and the email audience interviews from both countries. The results show some significant differences between the two countries as well as the similarity that Anti-Korean Wave discourses have been actively produced and disseminated through on-line media. As for Indonesia, the Anti-Korean Wave discourse pivots on the elements clashing between Indonesia's religion and cultural values and Korean consuming culture. According to the Anti-Korean Wave discourse, K-pop contents and entertainers are criticized for damaging the society's morals and cultural identities based on Islamic rules and values. Thus, the sentiment of the Anti-Korean Wave is likely to lead to the cultural nationalism for the sake of their cultural identity. As for Vietnam, anti-Korean Wave discourse mainly consists of issues on enthusiastic K-pop fans' anti-social behaviors and generational conflicts which are presumed attributed as the chief factor of the Anti-Korean Wave. In the Vietnamese discourse, social elites and adults treat the enthusiastic K-pop fans as those who are in need of educational care or psychological therapy. Unlike the Indonesian case, anti-Korean Wave discourse in Vietnam criticized the K-pop and the performer's competence for being cheap sexy and incompetence. They also denounce Korean dramas for their trite, typical story lines, use of excessive emotion, and unrealistic nature. However, the two country's interview participants have in common both acknowledged that rather than considering the Anti-Korean Wave as an issue that needs to be resolved it should be embraced as a natural cultural phenomenon.

This study defined the Creators who produce video contents related to Korean Wave in the form of one-person media and takes an influential role in China as the 'Korean Wave(Hallyu) Wanghong Media'. This study aimed at examining the effects of viewing motivation and behavior on satisfaction and cultural acceptance. The survey was conducted on 240 respondents who have watched the contents on China's Bilibili video site. As a result, among five different motivations, the higher the level of 'cultural curiosity', 'entertainment', and 'empathy', the higher the satisfaction. Examining the effect of viewing behavior on satisfaction, 'frequency', the act of 'sharing' and 'participating' had positive effects. Furthermore, 'cultural curiosity' and 'satisfaction' were the factors of positive influence on cultural acceptance. The results of this study can enhance the understanding of Korean Wave Wanghong Media and further contribute to continuous development.

배전 계통에서는 전동기의 시동 전류, 변압기의 여자돌입전류, 콘덴서의 고주파 과도 돌입전류 등의 과전류가 흐르므로, 회로 보호용 한류 퓨즈가 엘리먼트의 피로나 열화 등에 의해, 예기치 못한 용단이 발생한다. 이 경우 고장을 미연에 방지하기 위해, 한류 퓨즈의 신뢰성을 보다 향상시키기 위해서는 제품 특성의 균일성을 확보함으로서 그 사용 실태에 대응해서 적절히 교환하는 것이 필요하다.

전력계통 적용을 위한 초전도 한류기의 개발에서 빠질 수 없는 것이 용량 증대 방안이다. 여기서는 자속결합형 초전도 한류기의 용략 증대 측면에서 2차측 초전도 소자의 수를 늘렸을 때 사고전류 제한 특성과 초전도 소자의 권치 특성을 분석하였다. 소자의 수가 증가함에 따라 사고전류의 크기는 조금 증가 하는 것을 확인할 수 있었고, 초전도 소자의 전압은 크게 감소하는 것을 확인할 수 있었다. 이것은 초전도 소자 하나가 부담하던 사고전류를 분담하였기 때문에 소자의 부담이 줄어든 것이다. 실험을 통해 초전도 소자의 ��치시간도 알 수 있었는데 초전도 소자가 증가함에 따라서 ��치시간이 길어졌다. 이것은 초전도 소자의 치 시점이 늦어져 빠른 스위칭 동작을 할 수 없게 된다는 것이다. 초전도 소자의 수 증가는 소자의 부담을 감소시키고 용량증대를 측면에서는 장점이지만 스위칭 동작측면에서는 단점으로 작용한다.

일반적으로 저압계통의 고장전류를 차단하기 위해 설치된 차단기의 차단원리는 주로 역전압발생법올 이용하고 있다. 역전압발생법은 효과적으로 저압계통의 고장전류를 차단할 수 있으나, 제한된 한류성능과 긴 아킹 시간은 차단기는 물론 주변 전력기기에 전기적/열적/기계적 스트레스를 주게 된다. 국내외 업체는 고장전류를 보다 빠르고 효과적으로 제한 및 차단을 할 수 있는 한류형 차단기를 제안하고 있는 실정이다. 저압계통의 경우, 정온도계수 (Positive Temperature Coefficient, PTC) 특성을 가지는 한류소자를 기존 차단기에 직렬 혹은 병렬로 연결하여 저압계통의 고장전류를 매우 빠르고 효과적으로 제한 및 차단하는 추세에 있으며, 또한 PTC 한류소자를 이용함으로써 저압계통의 차단보호협조를 효과적으로 구현하고자 하고 있다. PTC 한류소자는 소자는 열팽창이 큰 비전도성 성분과 열팽창이 작은 전도성 성분이 혼합되어 구성되며, 소자의 온도가 증가함에 따라 비전도성 성분이 상대적으로 큰 부피 팽창을 하여 저항이 증가하게 된다. 이러한 PTC 소자를 전력계통에 적용함으로써 고장전류에 따른 줄열에 의한 저항증가로 고장전류를 제한하게 된다. 본 연구에서는 일반적으로 배터리 보호용으로 사용되는 폴리에틸렌 수지 및 카본블랙으로 구성된 폴리머 PTC 한류소자를 이용하여, 기존의 저전력 배터리 보호 폴리머 PTC 소자로부터, 저압계통의 단락사고시 발생하는 단락전류를 효과적으로 제한할 수 있는 대전력 폴리머 PTC 소자를 개발하였다.

The maximun short circuit current of modern power system is becoming so large that circuit breaker is not expected to be able to shut down the current in the future In order cut over-currents, a system composed of a superconducting fault current limiter(SFCL) and traditional breaker seems to provide a promising solution for furture power operation. In present paper, three line-to-ground fault is assumed to happen at the center of 345kV transmission lines in a large capacity electric power system. The superconducting fault current limiter was represented using a commutation type, which consists of a non-inductive superconducting coil and current limiting element (resistor or reactor). from the viewpoint of current limiting performance, the prevention of the voltage drop at the load bus and comparision characteristics for two type SFCL. Desired design specification and operation parameters of SECL were also given qualitatively by the performance.

The application of a large power transformer into a power distribution system was inevitable due to the increase of power demand and distributed generation. However, the decrease of the power transformer‘s impedance causes the short-circuit current of the power distribution system to increase and thus, the higher short-circuit current exceeds the cut-off ratings of the protective devices such as a circuit breaker. To solve these problems, several countermeasures have been proposed to protect the power system effectively from the higher fault current and the superconducting fault current limiter (SFCL) has been expected to be the promising countermeasure. However, the current limiting effect of SFCL including its bus voltage drop compensation depends on SFCL's application location in a distributed power system. In this paper, the current limiting and the bus-voltage drop compensating characteristics of the SFCL applied into a power distribution system were studied. In addition, the quench and the recovery characteristics of the SFCLs in each location of the power distribution system were compared each other.

It is very important for power stability to suppress the excessive fault current happened frequently in the real power grid The superconducting fault current limiter (SFCL) is one of the most effective ways to reduce the fault current among the facilities developed so far. In this paper, we have investigated the operating characteristics of the power grid with the SFCL according to three types such as the single, double and triple line-to-ground faults. In addition, we analyzed the consumption power of the superconducting units based on the working data of the SFCL. We confirmed that the fault current could be limited lower than its peak value to 85 percentage in initial fault condition and to 85 percentage after one cycle in the matrix-type SFCL. The consumption powers of the superconducting units were almost equal by reduction of the difference of the critical current between superconducting units element.

We fabricated a resistive SFCL having a shunt resistor parallel to it in order to bifurcate the transient current at faults. The SFCL consists of a YBCO film coated with an Au layer (10 ${\omega}$ at room temperature), which is to disperse the heat generated at hot spots in the YBCO film, and the 5 ${\omega}$ shunt resistor. The minimum quench current of the SFCL was found to be 12.2 A$_{peak}$. This SFCL successfully controlled the fault current below 23 A$_{peak}$ which is otherwise to increase up to 113 A$_{peak}$. Bifurcation of the current resulted in the temperature rise of the YBCO/Au film 3 times slower than without the shunt, protecting the SFCL at high currents.
