전자 사이클로트론 공명 플라즈마 화학적 기상 증착 장치에서의 수소 플라즈마 특성연구

김우준(Woo-Jun Kim),구자춘(Ja-Chun Ku),황기웅(Ki-Woong Whang) 한국진공학회(ASCT) 1994 Applied Science and Convergence Technology Vol.3 No.3

Electron cyclotron resonance plasma chemical vapor deposition(ECRPCVD) 장치에서 공정변수에 따른 수소 플라즈마 특성을 조사하였다. 균일한 플라즈마 밀도를 얻기 위하여 전자공명층이기판과 평행하게 형성되도록 정자장 코일을 설계하였으며, 기판근처에 부가적으로 형성된 multicusp field에 의해서 기판 근처에서의 플라즈마 균일도를 개선시킬 수 있었다. 또한, 절연된 공진실과 기판에의 독립적인 DC bias에 의해서 기판으로 입사하는 하전입자들의 에너지와 유량을 조잘할 수 있었다. 이러한 플라즈마 특성을 갖는 ECRPCVD장치를 다양한 특성을 갖는 박막 합성에 응용할 수 있으리라 사료된다 The characteristics of the hydrogen plasma were investigated as functions of the process parameters in the electron cyclotron resonance plasma chemical vapor deposition(ECR-PCVD) system. The external magnet coils was designed such that ECR layer is parallel to the substrate to obtain a uniform plasma density, and the uniformity was improved by the additional multicusp field near the substrate. By the applications of independent DC biases to the cavity and the substrate, the energy and the flux of the charged particles in the plasma could be controlled. It is thought that this ECRPCVD system can be applied to the large and uniform coating having various properties.

A volute (or scroll) of a centrifugal compressor collects the flows from impeller or diffuser, and passes it to a pipe at the exit. This flow still contains some kinetic energy which is not converted into pressure at diffuser, thus volute designer must concern the way to minimize losses. This study defines some variables which determine the shape of volute, and carry out computational analysis based on Design of Experiment to optimize the performance of volute.

근대 이전의 한국 민간경비제도 고찰

김우준(Kim, Woo Jun) 한국민간경비학회 2012 한국민간경비학회보 Vol.11 No.2

이 연구에서는 관련 문헌의 조사ㆍ분석을 통하여 고대 연맹국가시대, 삼국시대와 통일신라시대, 고려시대, 조선시대(1863년 이전)라는 시대적 구분을 기준으로 각 시기별로 주요한 민간경비제도들을 소개하고그 특징점을 분석ㆍ정리하였다. 고조선의 위만이 거느린 유이민 세력과 부족민, 하호, 노비의 활동에서 고대 연맹국가시대의 민간경비 활동상을 추론할 수 있었다. 삼국시대에는 고구려, 신라, 백제에서 공통적으로 귀족이 보유한 사병적 경비조직이 신변경호, 시설경비 등의 기능을 수행했음이 확인되었다. 통일신라기에는 장보고가 이끈 청해진세력은 보안산업의 기능을 수행했음을 알 수 있었고, 신라 하대에는 각 지방의 호족들이 사병을 보유하여 경비를 담당하였고, 지역의 호부층과 농민이 중심이 된 향촌의 자위조직이 형성되어 자율방범활동을 펼친 기록도 있다. 고려시대에는 무신집권기의 사설 경비 기구라 할 수 있는 도방, 가병, 마별초 등이 민간경비 기능을 수행하였으며, 고려말 조선초의 시기에 귀족ㆍ권력가 집단이 보유한 사병 집단은 왕조 교체의 주된 배경이 될 정도였다고 분석된다. 조선시대 초기에도 왕족 및 귀족이 사병을 보유하여 자경활동을 하였으며, 계유정란 등 정치사적 주요 사건에도 권세가의 사병ㆍ경비집단이 관여하였던 것으로 보인다. 기타 영조대의 꼭지단이나 흥선대원군이 부렸던 무력 집단에 관한 사료에서 조선시대에도 여러 형태의 민간경비 내지 사적 경비집단이 형성되었음을 알 수 있다. 이 연구에서의 설명이나 주장은 대부분 추론에 바탕을 두고 있으며, 추후 후속 연구를 통하여 정밀하고 철저한 고증을 거쳐서 확인해 가야 할 과제를 안고 있으나, 많은 역사적 스펙트럼 속에서 민간경비사적으로 의미있는 사료들을 발췌ㆍ고증하여 후속 연구의 편의를 도모한 점에서 그 의의가 있다고 할 것이다. This study was performed for considering about korean private security systems in pre-modern era; Go Joseon(old Joseon) period, Three kingdoms period, Koryo period, early Joseon period. In the Go Joseon(old Joseon) period, drifting people group led by Wiman could considered as a kind of private security group. And lower class people or slaves took a role as private security resources. It could be ascertained that private army group possessed by aristocrats performed as private security resources in three kingdoms period. In the unified Silla period, Chang pogo established Cheonghaejin(quasi-private naval base) on Wando Island and swept the pirates from the seas and led the overseas trade of East Asia Sea. In the late of unified Silla period, local aristocrats, the riches and peasants had a neighborhood crime prevention guard organizations as vigilante corps. In the Koryo dynasty military official administration, special organizations(for instance, Dobang, Mabyoulcho, Choi’s House troops) performed as a role of private security group. From late Koryo to early Joseon, private army group possessed by aristocrats contributed to open new dynasty(Joseon) era. In the Joseon period, some royal families and aristocrats possessed their own private army groups and held vigilance activities. Records of some critical political events like the Kaeyou-Jungran(a coup d’etat in 1453) testified that some royal families and aristocrats possessed their own private army groups. Focusing on historical scientific deduction, documentary researching method and domestic review of advanced research could be mentioned as limitations or flaws, but it has academic contributions and meaningfulness considering to construct the base of future studies, despite lack of related research.

조선족에 대한 한국과 중국의 역사적 인식 비교

김우준(Kim, Woo-Jun),정갑영(Chung, Kap-Young) 백산학회 2006 白山學報 Vol.- No.74

This study has investigated the significant differences in China’s and Korea’s perception of Korean Chinese. Although there is dispute within domestic academic circles, Korea sees the origins of Korean Chinese in the Gando settlers. Of course, within Korean academia there are those that deny the existence of aGando problem. Because China officially denies the existence of any problem over Gando ownership, China argues that Korean Chinese originated from cross-border immigrants. However as has been made clear, China’s Northeastern Project is proof that the Chinese government acknowledges existence of a dispute over Gando ownership and is preparing to defend their position. Note that due to Korea’s strong position on the dispute over the history of Goguryeo, China has shown hesitation on the Goguryeo issue. Inasmuch, the Chinese government has encouraged the Goguryeo issue to be resolved among academics of both countries. However, because Gando issue is a territorial problem of a highly sensitive nature, Chinese officials explain that the Chinese government has decided to deal with it officially. The problem of Korean Chinese is directly related to the Gando issue. In 1909 Japan and the Ch’ing Empire signed the Gando agreement paying no respect to the claims of the Korean people. By this agreement, Korean settlers of Gando and Gando itself became victims of Japanese imperial aggression and China’s Big Nation policy. As the People’s Republic of China was established in 1949 and Yan-bian Korean Ethnic Autonomous District established in 1955, Gando settlers inevitably became co-opted as Korean Chinese. Such history gives rise to today’s differences in perception and policy between the two countries over Korean Chinese. That is, while Korea sees Korean Chinese as Korean expatriates in China and is beginning to perceive them as subject to Korean law, China argues that Korean Chinese are an ethnic minority in China and citizens of the People’s Republic, and therefore tries to suppress disturbance and secession. This explains China’s “Three Perspectives Policy.” Furthermore, as Korea has been pushing for changes on the Korean peninsula since 1990, it may be interpreted that China has hurried to implement its Northeastern Project in preparation to control the Korean Chinese and deal with the Gando issue. Korean Chinese are closely tied to not only the Korea-China relations of the past and present, but of the future as well. As a unified Korea comes to border Gando, Gando itself and Korean Chinese become inevitably involved with the future of Korea. The boundary treaty signed by North Korea and China in 1962 should be reevaluated and judged by a unified Korea. As China grows in power, it is increasingly emphasizing the Chinese nation and is predicted to try to control ethnic minorities to a greater degree in the future. However, as a multiethnic China comes to grapple with the question of future stability or chaos, the issue of Korean Chinese and Gando is predicted to face change. As shown, the differences between Korea and China in the perception of Korean Chinese have persisted in the past and present, and are foreseen to continue for a while into the future. Theissue of Korean Chinese currently forms an axis of the dynamics between the two countries, and should do so in the future as well. Although differences in perception and understanding may exist between the two countries, Korea and China should work towards mutual understanding and cooperation to further the advancement of the Korean Chinese community.

중국의 大國崛起와 남중국해 諸島 영유권문제

김우준(Kim, Woo-Jun) 백산학회 2009 白山學報 Vol.- No.83

It is between the late 1990s and the early 2000s that China and the rest of the world began to agree that the rise of China means the rise of a great power. Chinese themselves claim that the rise of China is identical to the rise of great powers in the history. Throughout the Chinese history, China has been pressing its own version of international order with both military and non-military means, expanding its national territory. A rising China in the 21st century never hesitates to expand its influence. As power shift is not obvious in East Asia as well as in the rest of the world, China maintains its cooperative posture, but, the way ahead is unpredictable and many cannot help worrying about the negative dimension to the rise of China. Analysis of the relationship between the rise of China and the Chinese claim to the islands in the South China Sea shows that the greater China has become, the more aggressive it has turned in its territorial claims. In other words, China changes its posture on territorial issues in proportion to changes in its national might. Issue of the islands in the South China Sea finds its presence in the maritime border strategy of China, which President Hu Jintao has mentioned. Announcing that China is transforming itself into a sea power from a continental power, he emphasized the need to build military might commensurate with its presence as a political and economic power. In addition, he underscores that other countries are occupying some of Chinese islands and sunken rocks illegally and claims that China is the only nation that has continental shelf. China argues that the issues of the islands in the South China Sea came about, as the neighboring countries occupied the islands on after another in the midst of commotion that engulfed China during the Cultural Revolution. China built military bases in the Paracel Islands and the Spratly Islands that it claims as territory and included them in its administrative jurisdiction. China also built a large nuclear submarine base in Hainan Island at the mouth of the South China Sea, which indicates the aggressive posture of China. Concerning the race of China and the U.S. to secure regional hegemony over the islands in South China Sea, Chinese scholars conclude that the U.S., a 3rd party to the territorial issue in the South China Sea, is trying to intervene and lay siege to China. The sea power strategy of China and the Asia-Pacific strategy of the U.S. are colliding head on in the South China Sea. China analyzes that if it clashes with one of the U.S. allies in the South China Sea militarily, the U.S. will intervene, which will pose a serious threat to the Chinese claims to its territories and interests in the sea. They predict with confidence that the U.S. will not be able to win a full-blown war with China.

주변 배경음에 강인한 구간 검출을 통한 음원 인식 및 위치 추적 시스템 설계

김우준(Woo Jun Kim),김영섭(Young Sub Kim),이광석(Gwang Seok Lee) 한국전자통신학회 2016 한국전자통신학회 논문지 Vol.11 No.8

본 논문은 비정상 상황 시 발생하는 음원에 대해 주변 환경 음에 강인한 음원 구간을 검출하여, 구간내의 신호를 이용한 음원 인식 과 위치 추적 시스템 설계에 관한 연구이다. 강인한 음원 구간 검출은 수신되는 오디오 신호로부터 단 구간 가중 평균 델타 에너지를 계산하여, 저역 통과 필터에 입력 후, 출력되는 결과 값들의 비교를 통해 배경음에 강인한 구간을 정의 하며, 음원 인식은 검출된 구간 내 데이터로부터 종래의 인식방법인 HMM(: Hidden Markov Model)을 이용해, 음원 인식 정보를 생성하여 학습 및 인식을 한다. 이는 주변 배경음이 포함된 음원 신호에 대해 기존 신호의 에너지를 이용해 구간을 검출 후, HMM을 통한 인식에 비해 3.94% 상향된 인식률을 보인다. 또한 인식 결과를 바탕으로 구간내의 신호간의 TDOA(: Time Delay of Arrival)를 이용한 위치 파악은 실제 발생 위치와의 각도와 97.44%일치함을 보인다. This paper is on a system design of recognizing sound sources and tracing locations from detecting a section of sound sources which is strong in surrounding environmental sounds about sound sources occurring in an abnormal situation by using signals within the section. In detection of the section with strong sound sources, weighted average delta energy of a short section is calculated from audio signals received. After inputting it into a low-pass filter, through comparison of values of the output result, a section strong in background sound is defined. In recognition of sound sources, from data of the detected section, using an HMM(: Hidden Markov Model) as a traditional recognition method, learning and recognition are realized from creating information to recognize sound sources. About signals of sound sources that surrounding background sounds are included, by using energy of existing signals, after detecting the section, compared with the recognition through the HMM, a recognition rate of 3.94% increase is shown. Also, based on the recognition result, location grasping by using TDOA(: Time Delay of Arrival) between signals in the section accords with 97.44% of angles of a real occurrence location.
