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.

Fluorescent fullerene nanoparticle-based lateral flow immunochromatographic assay for rapid quantitative detection of C-reactive protein

정진영,강태준,Mijin Choi,Da Jung Chung,Kyung Mi Park 나노기술연구협의회 2019 Nano Convergence Vol.6 No.35

A fluorescent fullerene nanoparticle (NP)-based lateral flow immunochromatographic assay (LFIA) was developed for the rapid and quantitative detection of C-reactive protein (CRP) in serum. The polyclonal CRP-antibody-conjugated fullerene NPs were simply prepared by 1-ethyl-3-(3-dimethyllaminopropyl)-carbodiimide hydrochloride coupling after carboxylation of fluorescent fullerene NPs. By applying the CRP-antibody-conjugated fullerene NPs to a lateral flow test strip, quantitative analysis of CRP in serum was possible at a concentration range of 0.1–10 ng/ml within 15 min. We anticipate that this novel fluorescent fullerene NP-based LFIA can be useful for the rapid and accurate sensing of biological and chemical species, contributing to the disease diagnosis and prognosis, environmental monitoring, and food safety.

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.

통상이념으로서의 개화사상과 위정척사사상

정진영(Chung Jin-Young) 21세기정치학회 2008 21세기 정치학회보 Vol.18 No.1

The debate between the Gaehwa Sasang and the Wijeongchuksa Sasang has almost always been perceived as that of a philosophical and ethical nature. Considering that the Chosun Dynasty's political and social order was constructed in a self-containing manner according to the Confucian philosophy, this situation is quite understandable. However, we, as the leading philosophers of the two thoughts did, have to pay attention to the reality of the late nineteenth century Chosun in which the two thoughts were developed and the debate took place. As always, trade with foreign countries can have a great impact on the various aspects of a country's domestic and international life including economic development, income distribution, national culture, and international relations. Therefore, whether or not to allow foreign trade was a very serious and challenging issue to the ideologues of the two thoughts at that time. In fact, they developed a fairly well organized system of ideas on trade to advance and defend their positions. Gaehwa theorists developed a trade ideology very similar to the theory of free trade. They believed that opening would bring to Chosun economic development, social and cultural reform, and international cooperation. Wijeongchuksa theorists developed an opposite idea on the impacts of trade on Chosun. They argued that opening trade with foreign countries would result in national immiserization, economic and cultural dependence, and the loss of national sovereignty.

한국 민주정치 발전을 위한 정치제도적 조건

정진영(Chung Jin-Young) 21세기정치학회 2010 21세기 정치학회보 Vol.20 No.1

Korean democracy is now more than 20 years old and there has been two power transitions between opposing parties. Most Koreans believe that there is no chance of the breakdown of Korean democracy and the turn to authoritarianism. Objectively, Korean democracy has been consolidated. At the same time, however, most Koreans are not satisfied with Korean democratic practice in the real world. Let's mention just several conspicuous examples: Adversarial confrontations are prevalent between the major parties resulting in political paralysis; presidents end up with their terms as another addition of a failed president; Representative democracy is in crisis; Political parties are subject to frequent realignments and they lack internal democracy within themselves; And people are sick and tired of physical violence of their representatives in the National Assembly. The present paper advances an argument that all these unwanted and unsatisfactory aspects of Korean democracy are based on an political institutional setting which lacks complementarity among its composing parts. Diverse institutions at different levels of the Korean political system provide conflicting incentives to politicians and produce non-conforming political activities, which prevents Korean democratic politics from moving toward an orderly and mature one and, instead, keeps political confrontation and paralysis as its repeating features. In order to overcome this state of affairs in Korean politics, we argue, constitutional amendments and political institutional reforms are to be carried out in such a way that institutional complementarity among Korean political institutions are strengthened. From this perspective, we propose 10 major institutional revisions that are needed in order to help the Korean presidential system of government function more smoothly and move towards a mature democracy.

정진영(Jin Yeong Chung),문두찬(Doo Chan Moon),권경술(Kyung Sool Kwon),정태안(Tae Ahn Chung) 대한피부과학회 1990 대한피부과학회지 Vol.28 No.3

Using peanut agglutinin(PNA), neurarninidase, and avidin-biotin peroxidase com plex(ABC) technique, normal skin specimens, nevocellular nevi, and malignant melanomas were studied, and different PNA binding patterns between nevocellular nevi and malignant melanomas were observed. The results were as follows : 1. In normal skin, except the basement membrane, epidermis and hair follicle epithelium showed a cell membrane staining of PNA after neuraminidase pretreat ment. Sebaceous glands revealed membranous and cytoplasmic staining of PNA, but sweat ducts were not stained. 2. In nevocellular nevi, none of the nevus cells were stained with PNA aftet neuraminidase preteatment. 3. In malignant melanomas, all of the melanorna cells were stained along the cell mernbrane with PNA after neuraminidase pretreatment. Therefore, the PNA staining after neuraminidase pretreatment on paraffin embedded sections using ABC technique is considered to be a useful probe for the differentiation between malignant malanoma and nevocellular nevus.
