          米軍政時代における「避難民」の誕生 -「解放」後の朝鮮半島を巡る国際情勢と人の移動-

          高旻成 동서대학교 일본연구센터 2018 次世代 人文社會硏究 Vol.0 No.14

          The problem of “Defectors from N. Korea (so-called “Talbook-ja” in S. Korea today)” has been received attention in the international society, especially in S. Korea today. It has been viewed as a “Refugee” problem or the output by system competition between the two Koreas. Actually, This problem has stood out rapidly since the collapse of “the Cold war system”. So, It may be able to recognise as a “Refugee” problem of international society. But we should have in mind that “Talbook-ja” often used as a political material in S. Korea since raised “the Cold war system”. Moreover, It means the movement from North to South existed not only during the Cold war age but before then. And ultimately, for these movers has condensed the reality of divided Korean peninsula, we could think that the prototype of “Talbook-ja” has already existed in the age of liberated Korea before “the Cold war system” had begun in earnest. However, In the age of liberated Korea, The U.S. and U.S.S.R. had established military government in South and North Korea. Nevertheless, We can hardly find out the view of Korean society that North and South are different nations. Because Korean Society had “One Korea” recognition at that time. So this paper should check that the presence of the political view on these movers in the age of liberated Korea and why “Talbook-ja” has become a political material. The contemplation about the process of shaping the “Refugee” in the age of liberated Korea could be the first step of grasp the root about “Talbook-ja” recognition. 今日の韓国及び国際社会においては、「脱北者」問題が多くの注目を浴びているが、この問題は冷戦体制の崩壊で急激に多く見られるようになったためか、南北朝鮮間における「難民」や南北体制競争の遺産といった視点で用いられることが多い。南北朝鮮における政治的材料として利用されてもきた当問題だが、結局のところ、このような移動者は冷戦時代から存在していたことを念頭に置かねばならないだろう。その上、この移動者には、南北分断の現実が凝縮されているともみられるが、究極的に冷戦が本格化する直前である「解放」時代から「脱北者」の原型は存在していたと考えるのが妥当である。ただ、「外部勢力」である米国とソ連による軍政が南北朝鮮に敷かれていた「解放」時代をみると、朝鮮社会における「一つの朝鮮」の考えが強かったためか、朝鮮半島における南北各々の「国家」という視線を見出すことは殆どできない。つまり、ここで確認すべきは、「解放」時代には移動者に対する政治的な視線が存在していたのかという点に併せ、この「脱北者」が政治的観点でみられるようになった理由は何であるのか、という点である。そこで本論では、「解放」時代における「避難民」の形成過程の考察を試みようとしているが、これが今日に至る「脱北者」に対する視線の根源を探る第一歩になると展望している。

        • PCB에 실장된 Gull-Wing Type Lead검사를 위한 영상처리 알고리즘에 관한 연구

          고민성,오영석 금오공과대학교 산업기술개발연구원 2000 産業技術開發硏究 Vol.16 No.-

          As the parts of printed circuit boards in these days are more integrated and smaller, new solder joints packaging technologies have also been developed. Up to now, a lot of algorithms have been developed to inspect the status of Gull-Wing Type Lead mounted on printed circuit boards. But, They are not perfect to overcome the inspection environments like as the visual noise and variations in component conditions. Therefore, in this paper presents the techniques used to inspect for Gull-Wing Type Lead mounted on printed circuit boards. In the inspection of solder joints, the features selected for solder joint inspection are projection of gray level image and the normalizing processing of projection data. The inspection of solder bridges is done by checking the width between the solder joints for projection data which represents the presence of solder. This paper includes some processing steps such as pre-processing method, adjust processing method, mask lead method and partition projection processing method. To show the effectiveness of the proposed algorithms, Experimental results showed that these algorithms are reliable for solder joint defects.

        • H∞를 이용한 필터 및 제어기의 개발

          고민성,김한실 울산대학교 1995 공학연구논문집 Vol.26 No.1

          미지의 예기치 않은 noise에 의해 영향을 받은 시스템을 제어하기는 쉽지 않다. 그리고 강인성과 low performance measure를 가진 제어 시스템을 설계하기는 더욱 어렵다. 이러한 문제를 해결하기 위한 시도는 계속되어 왔으며 이 중 Kalman Filter는 system noise 및 measurement noise가 오직 gauss distribution을 가지고 noise에 대한 정보가 있을 경우 optimal filter 임이 알려져 있다. [1-3]. 그러나 실제로 이러한 noise가 반드시 gauss distribution을 갖는 noise라고 할 수 없으며 또한 noise에 대한 정보가 전혀 없을 때는 optimal filter를 설계할 수 없으므로 입·출력이 bounded할 수 있도록 suboptimal 개념의 새로운 제어기의 설계가 필요하다. 본 논문에서는 noise에 대한 정보가 필요없고, 어떠한 noise라는 가정이 없는 H infinity 제어기 구성이 강인하고 low performance measure를 가진 제어기임을 실험을 통해서 보여주고, 산업현장에 응용할 수 있는 가능성을 제시한다. In the field of control and instrumentation, it is very difficult to control system which is affected by unknown and unexpected noise. Therefore, if we can design controller with robustness and small performance measure, it will be used extensively in the industrial application. Although it may be hard for designers to implement such a controller, it has been studied continuously for several decades. As a result, recently a few of control design methods give a solution with a good performance and robustness[4],[6-9]. We suggest that H infinity controller can be applied extensively in the industrial field that is affected by extremely deteriorated noise source. In this paper after constructing the Inverted Pendulum as an experimental apparatus, we design PID, Fuzzy, and H∞ controller to compare its characteristic results. If the similar design method with this paper is applied to the industrial filed, it may give a good solution with robustness and low performance areas can be shown in the field of signal processing, motor control, sensor interfacing, robot control.

          米軍政時代における「避難民」の誕生 ―「解放」後の朝鮮半島を巡る國際情勢と人の移動―

          고민성 ( Koh Min-sung ) 동서대학교 일본연구센터 2018 次世代 人文社會硏究 Vol.14 No.-

          今日の韓國及び國際社會においては、「脫北者」問題が多くの注目を浴びているが、この問題は冷戰體制の崩壞で急激に多く見られるようになったためか、南北朝鮮間における「難民」や南北體制競爭の遺産といった視点で用いられることが多い。南北朝鮮における政治的材料として利用されてもきた當問題だが、結局のところ、このような移動者は冷戰時代から存在していたことを念頭に置かねばならないだろう。その上、この移動者には、南北分斷の現實が凝縮されているともみられるが、究極的に冷戰が本格化する直前である「解放」時代から「脫北者」の原型は存在していたと考えるのが妥當である。 ただ、「外部勢力」である米國とソ連による軍政が南北朝鮮に敷かれていた「解放」時代をみると、朝鮮社會における「一つの朝鮮」の考えが强かったためか、朝鮮半島における南北各?の「國家」という視線を見出すことは殆どできない。つまり、ここで確認すべきは、「解放」時代には移動者に對する政治的な視線が存在していたのかという点に倂せ、この「脫北者」が政治的觀点でみられるようになった理由は何であるのか、という点である。そこで本論では、「解放」時代における「避難民」の形成過程の考察を試みようとしているが、これが今日に至る「脫北者」に對する視線の根源を探る第一步になると展望している。 The problem of “Defectors from N.

          고에너지 밀도 바나듐 레독스 흐름 전지를 위한 망간산화물 촉매와 다공성 탄소 기재의 시너지 효과

          김민성,고민성 한국표면공학회 2019 한국표면공학회지 Vol.52 No.3

          The carbon electrode was modified through manganese-catalyzed hydrogenation method for high energy density vanadium redox flow battery (VRFB). During the catalytic hydrogenation, the manganese oxide deposited at the surface of the carbon electrode stimulated the conversion reaction from carbon to methane gas. This reaction causes the penetration of the manganese and excavates a number of cavities at electrode surface, which increases the electrochemical activity by inducing additional electrochemically active site. The formation of the porous surface was confirmed by the scanning electron microscopy (SEM) images. Finally, the electrochemical performance test of the electrode with the porous surface showed lower polarization and high reversibility in the cathodic reaction compared to the conventional electrode.

          Pump cap is a product that is widely used due to its ease of use and simple operation. These pump caps are applied to heterogeneous functional cosmetics and are being developed as dual pump caps. However, the conventional dual pump cap has a problem in that it is inconvenient to use and leakage occurs. In addition, it is formed of a plurality of materials, and there is a problem that is difficult to recycle. Lately, since the problem of environmental pollution is getting serious, the dual pump cap, which is difficult to recycle, cannot be used. Currently, eco-friendliness has been considered in Korea, and there are no dual pump cap containers with excellent sealing performance. Therefore, in this study, a dual pump cap container made of eco-friendly material was designed. In addition, finite element analysis was performed to verify the design feasibility of the product.

          탄소나노튜브/흑연펠트 전극의 산소작용기를 활용한 바나듐 레독스 흐름 전지의 수소발생 억제 효과

          김민성,고민성 한국표면공학회 2021 한국표면공학회지 Vol.54 No.4

          Vanadium redox flow batteries (VRFB) have emerged as large-scale energy storage systems (ESS) due to their advantages such as low cross-contamination, long life, and flexible design. However, Hydrogen evolution reaction (HER) in the negative half-cell causes a harmful influence on the performance of the VRFB by consuming current. Moreover, HER hinders V2+/V3+ redox reaction between electrode and electrolyte by forming a bubble. To address the HER problem, carbon nanotube/graphite felt electrode (CNT/GF) with oxygen functional groups was synthesized through the hydrothermal method in the H2SO4 + HNO3 (3:1) mixed acid solution. These oxygen functional groups on the CNT/GF succeed in suppressing the HER and improving charge transfer for V2+/V3+ redox reaction. As a result, the oxygen functional group applied electrode exhibited a low overpotential of 0.395 V for V2+/V3+ redox reaction. Hence, this work could offer a new strategy to design and synthesize effective electrodes for HER suppression and improving the energy density of VRFB.
