페라이트 층을 갖는 유전체 슬랩 도파관 격자 구조의 해석
윤상원,Yun, Sang-Won 대한전자공학회 1989 전자공학회논문지 Vol. No.
페라이트 층을 갖는 유전체 도파관이 갖는 비가역 전자파 전파특성을 아이솔레이터와 같은 비가역 소자에 응용 가능하도록 페라이트로 되어 있는 격자 구조를 제시하였다. 격자 구조를 유전체 도파관의 계단형 불연속이 cascade로 연결된 것으로 보고, 모드 정합법으로 구한 계단형 불연속의 산란 행렬을 이용하여 격자 구조의 특성을 해석하였다. 주기적인 격자 구조의 저지 주파수 대역이 사용하고자 하는 주파수 근처에 있을 때와 상당히 떨어져 있는 두 경우의 비가역 산란 특성을 35GHz 근처에서 해석하였으며, X-Band에서 제안된 격자 구조를 제작 실험하였다. In this paper, dielectric waveguide gratings, which can be applied to the nonreciprocal devices such as isolators, are proposed. Those grating structures can be considered as cascade connections of step discontinuities between uniform dielectric waveguides and another uniform dielectric waveguides with a ferrite layer. Therefore, the nonreciprocal scattering characteristics of such gratings can be obtained form the scattering characteristics of step discontinuities and uniform dielectric wave guides. For the periodic grating structures, band-reject characteristics can be located inside or outside the frequency range of interest. Numerical analyses are performed at 35GHz and experimental results at X-band are also presented.

The NiSi is very promising candidate for the metallization in 45 nm CMOS process such as FUSI(fully silicided) gate and source/drain contact because it exhibits non-size dependent resistance, low silicon consumption and mid-gap workfunction. Ni film was first deposited by using ALD (atomic layer deposition) technique with Bis-Ni precursor and $H_2$ reactant gas at $220^{\circ}C$ with deposition rate of $1.25\;{\AA}/cycle$. The as-deposited Ni film exhibited a sheet resistance of $5\;{\Omega}/{\square}$. RTP (repaid thermal process) was then performed by varying temperature from $400^{\circ}C$ to $900^{\circ}C$ in $N_2$ ambient for the formation of NiSi. The process temperature window for the formation of low-resistance NiSi was estimated from $600^{\circ}C$ to $800^{\circ}C$ and from $700^{\circ}C$ to $800^{\circ}C$ with and without Ti capping layer. The respective sheet resistance of the films was changed to $2.5\;{\Omega}/{\square}$ and $3\;{\Omega}/{\square}$ after silicidation. This is because Ti capping layer increases reaction between Ni and Si and suppresses the oxidation and impurity incorporation into Ni film during silicidation process. The NiSi films were treated by additional thermal stress in a resistively heated furnace for test of thermal stability, showing that the film heat-treated at $800^{\circ}C$ was more stable than that at $700^{\circ}C$ due to better crystallinity.
시베리아내전기 연해주 수찬지방 한인빨치산부대의 조직과 활동

The paper presents an in depth study on the establishment of an anti-Japanese partisan in Suchan province of the Primorskii kraii during the Siberian Civil War. The Suchan Korean Partisan Army(SKPA hereafter) initiated various Korean armed forces and the Red Army in Siberia. It was organized in 1918 in the Nikolayevka(Sinyeong-dong), a local Korean village in Suchan province. After the SKPA was reorganized in late 1920, it was associated with other local units of the Korean and Russian Partisan in the Third-Fuzin, named 'Primorskii kraii Korean Conference'. The study deals with the historical development of SKPA focusing on significant issues that shaped its heroic contribution. The movement which was guided by a socialist principle as majority of its army were peasant farmers from Suchan province. Contact with the Russian partisan forces of the region strengthened its socialist nature. It underwent the process of dissolution until it was finally reorganized. Incidents like the uprising of the Czech Republic army and the dispatch of Japanese military in Siberia among others contributed to its further development. It also followed extension and integration with other Korean nationalist movement as well as in Far East of Russia. Finally, a major turnaround happened as the movement tried to consolidate after the April incident in Primorski Kraii. It then continued to fight against imperialist intervention group and the White Army.
러시아 민족정책과 한인 소련의 민족정책 변화와 1937년 한인 강제이주
윤상원 ( Sang Won Yun ) 수선사학회 2013 史林 Vol.0 No.46
The purpose of this study is to elucidate the causes of Korean deportation from Russian Far East to Central Asia in 1937. From what has been discussed above, we can state the following two points. According to the decision of the Soviet government, the official aim of deportation is “to prevent the penetration of Japanese espionage in the Far Eastern Territory.” And given the international and domestic situations at that time, this concern of the Soviet government had a sufficient basis. In the late 1930s there was possibility of the Japanese invasion to the Russian Far East and some Japanese spies were doing espionage in the Maritimes. But if we have a little more in-depth study, we can find that the ultimate cause of deportation was to be changes in national polices of the Soviet Union. After the death of Lenin, the principle of national self-determination was not followed in the Soviet Union. Especially Stalin`s theory of socialism in one country encouraged Russian chauvinism. In the process of agricultural collectivization and construction of the socialist society, self-determination of the Minority and rights of the people were ignored. As a result, deportation of Koreans in Russia could be executed.
