미국의 대일압력과 요시다 노선의 대미협조외교에 대한 재고찰
김남은(金男恩) 한국일본문화학회 2018 日本文化學報 Vol.0 No.79
The most important issue in Japan"s postwar diplomacy is whether Japan chooses to be "cooperative" or "autonomous" American pressure. Although these two tendencies do not always appear consistently, the "cooperation" route characterized Japanese diplomacy, and its spirit has been passed down as the Yoshida Line. However, Yoshida Line attaches importance to America`s "cooperation" more than to anything else, trying to escape from an unequal relationship with the United States. In other words, the policy sought "independence" even though it was "formally autonomous" in the framework of "cooperation" with the United States. For Yoshida Shigeru to realize the peace treaty promptly, and Hayato Ikeda to develop relations with the United States as an equal partner, Eisaku Sato developed the Japan-US cooperative route to realize the return of Okinawa. In this way, it can be said that "cooperation" and "autonomy" are complementary and form a front-back relationship of the same act in Japan"s postwar diplomacy.
Quantization of the Current Induced by a Surface Acoustic Wave through a Quantum Point Contact

The acousto-electric currents through a quantum point contact induced by surface acoustic waves were observed. The current was found to be quantized at integer multiples of $ef$, where $f$ is the surface acoustic frequency. By using an interdigitated transducer with a 500 nm spacing between the gates, we produced surface acoustic waves at 2.456 GHz, which resulted in 1.18 nA quantized current when three electrons were transferred from the source to the drain at a time. Also, we found that the quantization is related to the a presence of a static quantum dot unintentionally formed in a quantum point contact.

음성급 서비스 위주로 설치되어 있는 국내의 구내통신 설비는 서비스와 무관한 접지 및 본딩에 관한 제방 규정이 미비한 상황이다. 고속, 광대역 서비스용 구내통신 설비의 신뢰성 제고를 위해 구내에 설치되는 기자재의 접지와 본딩에 관한 연구 및 표준안 작성을 구내통신운용의 효율성을 도모하기 위해 꼭 필요한 분야이다. 따라서 본고는 국내 접지현황 및 문제점을 고찰하고, 이에 비교할 만한 국외의 여러 접지 및 본딩에 관련한 기술표준을 살펴 본 후, 국내의 취약한 부분에 외국의 기술표준을 적용한다. 결과적으로 건물의 신/개축 시 구내통신설비에 맞는 접지와 본딩의 국내 기술표준안을 제시하여, 신뢰성있는 시스템을 제공하도록 관련된 모든 분야에 일반성과 효율성을 부여하고자 한다. Telecommunications provisions of the interior of a country which are established only for a voice service are inefficient in various rule of grounding and bonding that are not concerned with services. It is a essential part for planning out a efficiency when employing telecommunication, researching and writing standards bout grounding and bonding of materials that are established in telecommunication to consider reliability of telecommunication equipment for a wideband and high speed service. Therefore we investigated present conditions and problems of domestic grounding and observed foreign technical standards related to several grounding and bonding. The foreign technical standards are compared with the domestic immature parts. As a result, presenting a domestic technical standards about grounding and bonding fitted to telecommunicateion provision when building is constructed or reconstructed, all parts related to this can be given the efficiency and the generality to provide system which has reliability.
