김종욱,이배호 전남대학교 전자통신기술연구소 2002 전자통신기술논문지 Vol.5 No.1

The paper shows MPEG-4 FGS(Fine Granularity Scalability) using the scalable video encoding technique that is adapted by MPEG-4 standard and a scheme to improve its efficiency. MPEG-4 FGS is the encoding technique that has the good flexibility for various property of devices and bandwidth variation over the internet. To improve MPEG-4 FGS coding efficiency, we applied an encoding technique with temporal scalability. In other words, the base layer is encoded with the same technique as the typical MPEG-4 FGS and the enhancement layer is encoded by adding temporal scalability property In test results, we could know that had better coding efficiency in the case of adding temporal scalability for the enhancement layer.

Effect of RF Power on an Al-doped ZnO Thin Film Deposited by RF Magnetron Sputtering

김종욱,김홍배,Deok Kyu Kim 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.3

Transparent and conductive Al-doped ZnO thin films (thickness, 200 nm) were prepared on glass substrates via RF magnetron sputtering at room temperature, using a disk of ZnO mixed with 2 wt% Al_2O_3 as a target (diameter, 3 in). We investigated the effects of RF power (20 - 100 W, in steps of 20 W) on the structural, optical, and electrical properties of the fabricated thin films. The preferred orientation was observed on the (002) plane of all the Al-doped ZnO thin films deposited on the glass substrates. Moreover, good crystallinity was obtained in the RF power range of 40쭯80 W. All the Al-doped ZnO thin films exhibited more than 80% transmittance, regardless of the RF power; the optical band gap increased with the RF power. The best electrical properties were obtained at 80 W as follows: electrical resistivity = 1.76 ≠ 10^(-3) Ωcm, carrier concentration = 6.35 ≠ 10^(20) cm^(-3), and mobility = 5.57 cm^2V^(-1)s^(-1). The results of XPS analysis showed that the number of O vacancies and Al atoms were dependent on the RF power, and they were maximum at 80 W.

프랑스 식민지배하의 베트남 근대성 : 민주 개념의 형성을 중심으로 the Formation of Democracy

김종욱 한국동남아학회 2004 동남아시아연구 Vol.14 No.1

This paper examines the nature of democracy in the modernization process in Vietnam under th e French colonial rule in the early twentieth century. Since the World War I, th e internal and external factors provides favorable conditions for the Vietnamese int ellectuals discuss political liberalization and democracy. The Meiji Renovation mo vement in Japan, the K'ang Yu Wei and Liang Ch'i Chao's Renovation movement in Chinal, the Bolshevik Revolution in Russia gave lessons to the Vietnamese nationalist intellectuals. The victory of the French Socialist Party and the People 's Fronts also gave good chance for the Vietnamese to demand the political rights in the colony. On the other hand, the French colonial rule had escalate d colonial industrialization and had contributed to the accumulation of the Vietnam ese national capital. This development had effects on the nationalist democr atic movements. With this, there appeared the new social strata such as stude nts, teachers, officials, reporters who led the political struggles for more poli tical rights and freedom. Among them, there were at least three groups of the Vie tnamese intellectuals who led, organized, planned the political struggle for de mocracy against the French colonial authorities; the neo-confucian patriots, the r eformists and the radicals. In the first half of the twentieth century, there were two important events in forming the democracy in Vietnam; the confrontation between the Alexandre Varenne and the Vietnamese reformists in 1926 and th e dispute between the Stalinist and the Trotskyist in the Indochina Communist Par ty in 1937. The former event showed that the discords of the french authorities and the Vietnamese intellectuals had frustrated a good chance to transplant the wes tern bourgeois democracy into Vietnam in a peaceful way. Alexandre Varenne h ad to shackle himself owing to his contradictory position as a socialist an d as a colonialist. The traditional neo-confucian patriots failed to make more clear concept of democracy and concrete strategy to realize the democracy and lost their leading position in renovation movement. The reformists adhered to their positio n exclude the peasants and the workers in the political struggle against the Frenc h colonial government. They also kept close relationship with the French auth orities and therefore also lost their legitimacy in the nationalist movement. The radicals had yet consolidated their position in the intellectual movement at the t ime. Both the Vietnam Nationalist Party's members and the communists had to att empt vainly to lose themselves in forming the local organizations and in making the strategies. Therefore, each party's devotion to realize the democracy in the c olonized Vietnam was too independent to bring the western democracy into the Vi etnamese society. The latter event indicated that the ideological struggle among the communist camp missed an opportunity to realize the proletariat democracy(or dem ocratic centralism) in Vietnam. In the 1930s, the radicals, especially the commu nist met a favorable chance that the Third International(the Comintern), the French government of People's Front and the Indochina Communist Party had mad e. However, the French government had never sent the Committee of Inspection to Vietnam because of the severe interior opposition. The traditional patriots and the reformists had no longer played an important role in the mass political liberatio n movement. The Stalinist included Duong Bach Mai, Nguyen Van Tao who w ere the main forces in the Indochina Communist Party. They revealed their limits when the Indochina Congress was not held and the People's Front in Vietnam could no t rally all social strata to fight against the French colonial exploitation. Moreover , the Stalinist were mortally wounded as they cruelly put down the Trotskyist s including Ta Thau, Huynh Van Phoung, Le Van Thu who organized and led the g roup La lutte and advocated the proletariat democracy and democratic centralism.
