Objective : Although cingulotomy has been applied to patients with affective disorders more frequently, there are numerous reports of its use for the control of severe pain. The goal of this study was to investigate the role of stereotactic bilateral anterior cingulotomy for intractable cancer pain. Method : Between January and June, 2000, we underwent stereotactic bilateral anterior cingulotomy in 6 patients for intractable cancer pain with poor response to opioids. The patients were suffering from widespread musculoskeletal or visceral pain. We made four lesions along the two tracks on either side of the cingulate cortex. Result : In all patients, pain reliefs after cingulotomy were dramatic and immediate. Five out of six patients did not require any opioids and one patient could reduce dose of opioids. There were no deaths or serious complications related to the procedure. Conclusion : These results suggested that a bilateral anterior cingulotomy might be useful method to control intractable cancer pain associated with the widespread metastatic disease. To provide rationale of bilateral anterior cingulotomy in intractable cancer pain, the theoretical mechanisms and role of bilateral anterior cingulotomy are discussed, along with our surgical techniques and the course of our patients.

근래 휴대 단말기용 모뎀 칩셋이나 멀티미디어 프로세서의 CPU성능은 노트북PC에 버금가는 수준으로 향상되면서 휴대단말기가 전자기기의 컨버전스화를 주도하는 아이콘으로 떠오르고 있다. 더불어 DMB, 디지털 카메라, 화상통화, 인터넷 검색 등이 기본적으로 제공되면서 소형크기의 휴대 단말기용 디스플레이에서도 화질에 대한 관심이 높아지고 있다. 휴대단말기의 경우 야외에서 태양광과 같은 주변광원의 변화로 동일한 영상이 열화 또는 과도하게 밝아져 보이는 야외 시인성 문제를 해결해야 하며, 더구나 최근 터치방식 패널이 휴대단말기 디스플레이 장치에 사용되면서 ITO 필름에 의한 투과율 손실로 디스플레이 화면의 컨트라스트 저하가 더해지고 있다. 본 논문에서는 휴대 단말기용 영상개선 SoC를 위해 영상 개선 알고리즘을 개발하였고 이에 대한 성능 비교를 수행하였다. 컨트라스트 개선을 위해 적응형 기법으로 Clipped Histogram Stretching을, 정적 기법으로 S형 곡선조정과 Gain 조정 기법을 사용하였고 야외 시인성 개선을 위해서는 CIELCh 색공간에서 외부 조도센서의 정보에 따라 명도(Lightness)와 채도(Chroma)가 조절될 수 있도록 하였다. 개발한 알고리즘에 대한 성능평가는 결과영상의 히스토그램, RGB 화소값 분포도, 엔트로피 그리고 동적영역 확장비 등을 통해 분석을 진행하였다. Recently the CPU performance of modem chipsets or multimedia processors of mobile phone is as high as notebook PC. That is why mobile phone has been emerged as a leading ICON on the convergence of consumer electronics. The various applications of mobile phone such as DMB, digital camera, video telephony and internet full browsing are servicing to consumers. To meet all the demands the image quality has been increasingly important. Mobile phone is a portable device which is widely using in both the indoor and outside environments, so it is needed to be overcome to deteriorate image quality depending on environmental light source. Furthermore touch window is popular on the mobile display panel and it makes contrast loss because of low transmittance of ITO film. This paper presents the image enhancement algorithm to be embedded on image enhancement SoC. In contrast enhancement, we propose Clipped histogram stretching method to make it adaptive with the input images, while S-shape curve and gain/offset method for the static application And CIELCh color space is used to sunlight readability enhancement by controlling the lightness and chroma components which is depended on the sensing value of light sensor. Finally the performance of proposed algorithm is evaluated by using histogram, RGB pixel distribution, entropy and dynamic range of resultant images. We expect that the proposed algorithm is suitable for image enhancement of embedded SoC system which is applicable for the small-sized mobile display.

소형 모바일 디스플레이의 Local Dimming 백라이트를 위한 영상 컨트라스트 향상 기법

정진영(Jin-Young Chung),윤기방(Ki-Bang Yun),김기두(Ki-Doo Kim) 大韓電子工學會 2009 電子工學會論文誌 IE (Industry electronics) Vol.46 No.4

본 논문에서는 대형 TFT-LCD 장치에서 소모전력 개선방안의 하나로 사용되는 Local Dimming 백라이트 제어방식을 휴대단말기와 같은 소형 디스플레이에 적용하고자 이에 적합한 영상 컨트라스트 향상기법을 제안한다. 대형 디스플레이뿐만 아니라 소형 디스플레이 장치로 널리 각광받는 TFT-LCD의 광원인 백라이트 LED의 배치는 기존에 측면조사 구조로써 Global Dimming 방법이 사용되어졌으나 근래 진보된 기술을 통해 액정 후면에 배치, Local Dimming 방법이 제안되면서 입력영상을 블록단위로 분할 처리해야할 필요성이 대두되고 있다. 즉, 분할된 블록의 영상이 어두울 경우 해당 백라이트 LED의 공급전류를 감소시켜 명암대비를 극대화시킴과 동시에 소모전력량을 감소시키는 방법이다. 본 논문에서는 입력영상을 같은 크기의 블록단위로 분할한후 각 블록 내 화소정보를 분석하여 밝기성분(Y)에 대한 히스토그램과 평균, 표준편차 등의 정보를 획득하여 블록단위로 독립적인 컨트라스트 향상과정을 수행함으로써 영상정보를 통한 1차 컨트라스트 향상을 실현하고 동시에 블록단위결과 정보를 Local Dimming을 조절하는 백라이트 제어부로 전달하여 광원제어를 통한 2차 컨트라스트 향상과 동시에 전류소모 감소 목표를 실현하고자 한다. This paper presents the image contrast enhancement technique suitable for local dimming backlight of small-sized mobile display while achieving the reduction of the power consumption. In addition to the large-sized TFT-LCD, small-sized one has adopted LED for backlight. Since, conventionally, LED was mounted on the side edge of a display panel, global dimming method has been widely used. However, recently, new advanced method of local dimming by placing the LED to the backside of the display panel and it raised the necessity of sub-blocked processing after partitioning the target image. When the sub-blocked image has low brightness, the supply current of a backlight LED is reduced, which gives both enhancement of contrast ratio and power consumption reduction. In this paper, we propose simple and improved image enhancement algorithm suitable for the small-sized mobile display. After partitioning the input image by equal sized blocks and analyzing the pixel information in each block, we realize the primary contrast enhancement by independently processing the sub-blocks using the information such as histogram, mean, and standard deviation values of luminance(Y) component. And then resulting information is transferred to each backlight control unit for local dimming to realize the secondary contrast enhancement as well as reduction of power consumption.

세계금융과 민주주의의 관계에 관한 재고찰

정진영(Jin-Young Chung) 동아시아국제정치학회 2013 국제정치연구 Vol.16 No.1

The outbreak of the global financial crisis and the subsequent Euro crisis provide a good opportunity to reexamine the relationship between global finance and democracy. This is because the crisis period has lay bare the political foundation of the global financial system. Before the crisis, it was often presumed that financial globalization was an inevitable trend, as was the consequential restraint of democratic politics at the national level. Capital mobility hypothesis and financial policy trilemma have supported this view. Under the condition of high international capital mobility, nation states cannot avoid sacrificing their autonomy in pursuing their economic policies. In other words, democratic governments cannot be as responsive to popular demands, so long as they remain adherent to the demands from global financial markets. However, the outbreak of global financial crisis and subsequent developments put an end to the belief in the possibility of self-regulating financial markets and brought about widespread popular protests against the global financial system and strong demands for strengthening financial regulation. Polanyi’s concept of “double movement” provides an appropriate explanation of this turnaround. Comprehensive and strong financial regulatory reforms have been pursued at both the international and national levels since the crisis. Consecutive G20 summits have been providing political legitimacy and dynamics to this financial reform drive. The Financial Stability Board and the Basel Committee on Banking Supervision have been instrumental in designing and developing new regulatory measures. The so-called ‘systematically important financial institutions,’ or SIFIs, and the shadow banking sector have received special attention because they were believed to be the main weak points of the pre-crisis global financial system. Financial regulatory and supervisory agencies have also been strengthened in the countries of all the major economies. If all these reform measures are to be successfully adopted at both the national and international levels, we may live under a completely different global financial order in the years to come. However, there are still important obstacles ahead, which reflect the fundamental nature of the comtemporary global political economy; namely, the coexistence of globally integrated financial markets and nationally divided regulatory authorities. Under these kinds of circumstances we can hardly be sure that financial regulatory measures will be implemented optimally. This means that the shape of a new international financial order will also be determined through national and international political processes. This is why we argue that the relationship between global finance and democracy should be viewed not from an one-way structural perspective, but from that of a mutually constituting political process. When we adopt this perspective, we come to ascertain that we are living in a period of another great transformation through which democracy and global finance can find a new compromise for their stable coexistence.

중국의 부상과 국제통화·금융질서의 미래: 자유주의 국제질서가 붕괴될 것인가?

정진영 ( Jin-young Chung ) 경남대학교 극동문제연구소 2017 한국과 국제정치 Vol.33 No.1

중국의 부상이 자유주의 국제질서를 붕괴시킬 것이라는 주장은 미국의 패권이 쇠퇴하고 중국이 비자유주의 국가라는 사실에 기초한다. 그러나 이는 논리적이고 경험적인 검증을 필요로 한다. 이 글은 국제통화·금융질서의 측면에서 세 가지 사례를 통해 중국의 부상이 국제질서에 미치는 영향을 살펴본다. 첫째, IMF에 대한 중국의 영향력 증대이다. 세계금융위기 이후 중국은 국제통화체제 개혁을 적극 요구하였고, 그 결과 IMF에서 세 번째로 비중이 큰 이해당사자가 되었다. 중국의 국력신장이 IMF의 거버넌스 개혁에 반영된 결과이다. 둘째, 중국은 위안화 국제화를 위해 SDR 바스켓에 위안화를 편입시키려 했다. 국내적으로 금융개혁을 추진하고 국제적으로 사용이 용이하도록 하는 등 다양한 노력의 결과, 위안화는 SDR 바스켓을 구성하는 5개 통화들 중 하나가 되었으며 국제통화로서 인증받았다. 셋째, AIIB를 설립하여 중국 중심의 국제금융기구를 갖게 되었다. 중국은 막대한 금융자산을 기초로 적극적인 금융외교를 펼치고 있다. AIIB는 쌍무적·비공식적인 중국의 금융외교를 다자화·제도화하려는 노력으로서, 세계은행이나 ADB를 대체하기보다 경쟁하고 보완하는 역할을 한다. 이러한 사례들에서 중국의 부상은 자유주의 국제질서를 붕괴시키기보다 그 질서 속으로 중국이 더욱 깊숙이 편입되고 있음을 확인할 수 있다. 국제경제질서는 부상하는 국가들을 비교적 쉽게 포용할 수 있다. 국제통화 ·금융의 측면에서 중국의 부상은 자유주의 국제질서를 위태롭게 만들지 않고 있다. It is often argued that China`s rise will bring about the collapse of the liberal international order. This is based on two features of China`s rise: the relative decline of U.S. Hegemony and China`s being an illiberal country. However, this argument needs to be examined with regard to its logical reasoning and empirical foundation. We cannot tell logically that the decline of a liberal hegemonic country, the U.S., will necessarily end up with the collapse of the liberal international order. In this paper we take three instances exemplifying China`s rise in the field of international monetary and financial relations to examine their impacts on the liberal international order. First, the reform of the IMF and China`s rising power in it. After the global financial crisis China strongly argued for the IMF reform as a part of international monetary reform which caused the crisis, and now is the third most powerful state in the IMF in terms of its quota share and voting power. Second, China demanded that its currency, RMB, should be included in the currency basket of Special Drawing Rights(SDR). China made a variety of efforts to satisfy the criteria for the RMB inclusion into the SDR basket, and RMB is now an officially recognized international reserve currency. Third, China led an international effort to establish an international infrastructure investment bank and succeeded in launching the AIIB. AIIB can be perceived as China`s effort to transform its conventional bilateral and informal financial diplomacy towards a multilateral and institutionalized one. These instances show that rising China has been successfully accommodated into the liberal international order, rendering China to be its big stakeholder. As far as international monetary and financial relations are concerned, the liberal order has shown its flexibility and adaptability to accommodate a rising great power into it.

남북관광교류협력에서의 전시·컨벤션산업 역할에 관한 탐색적 고찰

정진영(Chung, Jin-Young) 한양대학교 관광연구소 2020 觀光硏究論叢 Vol.32 No.4

본 연구는 그동안 국내 문헌에서 제시되어 왔던 남북관광교류 방안들을 비교, 분석하고, 남북한 관광교류협력 증진을 위한 전시·컨벤션산업의 역할을 탐색적으로 고찰하고자 한다. 북한 자료 접근의 구조적 제약 때문에 국내학술지 및 언론보도를 통해 북한의 전시·컨벤션 현황에 대한 기초적인 이해도를 확보하였으며, 추가로 각종 보고서, 해외 언론 보도, 북한 매체 등을 편의적으로 조사하는 문헌고찰법을 실시하였다. 연구결과, 북한의 전시·컨벤션 분야는 관련 인프라, 법·제도 등을 비롯하여 산업 생태계 조성과 전문인력 육성 체계가 아직 미비한 상태로 보이지만, 인적, 물적 교류가 핵심 인컨벤션과 전시산업의 특성상 대외관계 개선에 마중물 역할을 할 수 있을 것으로 판단된다. 따라서, 지금과 같이 남북 간 국제관광 여건이 성숙되지 않은 상태에서는, 일반 관광객 방문교류보다는 전시·컨벤션 등 비즈니스 관광교류를 먼저 시도해야 할 것으로 생각한다. 본 연구는 북한 전시·컨벤션 현황 분석을 통해 북한 관광자원 및 남북관광 연구 발전에 기여하고 경색된 남북관계 개선과 함께 궁극적으로 남북관광교류협력 활성화를 위한 정책적 시사점을 제시할 수 있을 것으로 기대된다. The purpose of the current study is twofold. First, this study aims to compare and contrast the models of tourism cooperation between South Korea and North Korea that have been proposed in the literature so far, and second, this study examines the exhibition and convention industries in North Korea in order to explore the role of the industries in promoting tourism between South and North Koreas. Due to the limited access to the data, this study conducted the exploratory data collection process; that is, this study collected the information about the North Korea’s exhibition and convention industries from the academic publications and news media as much as possible, and additionally examined the empirical reports, Internet, and some materials published in North Korea. Results showed that the exhibition and convention industries are yet in the initial stage of the development process in North Korea; however, it seemed that the industries could facilitate and promote the relationships between South Korea and North Korea given the nature of the industries. It is also suggested that business tourism such as exhibition and convention should be considered prior to largely implementing leisure tourism cooperation between the two states (e.g., individual tourism).
