SUMMARY OF REGIONAL RESEARCH AND DEVELOPMENT CONSORTIUM ON NEXT GENERATION MANUFACTURING AND PRODUCTION PROCESSES OF DIES

IWABUCHI, AKIRA 경북대학교 트라이볼로지연구소 2001 INTERNATIONAL SYMPOSIUM ON HIGH PERFORMANCE OF TRI Vol.2001 No.-

In this paper, I would like to introduce the summary of the national research project on Next Generation Manufacturing and Production Process of Dies, sponsored by NEDO, Japanese Government from October, 1998 to March, 2000. We thought that the die production technology is the key to maintain the high level of Japanese industries. The project consisted of five research groups of die design technology, super-precision machining, corrosion protection in EDM, mold releasing agent, and production processes, and totally 19 sub-themes were carried out. We tried to confirm the performance of new polishing methods, and made new truing tool of profile-grinding. In relation to tribology, we tried to understand the wear mechanism of cemented carbide during operation against soft metals.

East Asian Rivalry, Digital Media and Proximate Enemies in Japan

Koichi Iwabuchi 서울대학교 아시아연구소 2018 아시아리뷰 Vol.7 No.2

The substantial expansion of global capitalism in the post-cold-war context has accompanied the ascent of Asian economies and (commercialized) cultures as most exemplified by China and South Korea. In contrast, Japan’s experience has been marked by the struggle with economic slump after the collapse of so-called bubble economy. Accordingly we have observed the intensification of economic and cultural rivalry between Japan, China and South Korea, joined together with political contestation over historical issues. This paper discuss the rise of anti-Chinese and Korean sentiment in Japan, which also generates hate-speech movement against resident Koreans. It will be argued that growing East Asian rivalry with the relative decline of Japan, the vague sense of socio-economic frustration and the upsurge of digital media communication have been complicatedly conjoined to engender the attack and hunt of proximate enemies as the object of expression of dislike.

近世 · 近代移行期における日本の首都空間の変容の一斷面-旧江戶城門の再編成を中心に

일본의 수도, 도쿄의 중심에는 1.5㎢를 차지하는 천황의 주거, ‘황거 皇居’가 존재한다. 이는 도쿄의 모체였던 도시 에도가 성을 중심으로 한 죠카마치 城下町의 형식을 취한 도시였으며, 황거는 에도성의 공간을 이용하였기 때문이다. 에도성은 국내의 정치적인 안정으로 의례를 통한 쇼군 將軍의 권위를 선양하는 장소로 기능하였다. 이중으로 해자를 두르고 중핵에는 도쿠가와 쇼군가 德川將軍家의 거처와 정무공간, 그 외 관청이 위치하였다. 해자에는 다리와 성문이 설치되었으며, 쇼군의 방문자와 외출하는 쇼군 행렬의 송영이 성문에서 행해졌다. 성문은 서열의 확인과 권위를 발현하는 장으로 기능하였다. 근대에 들어오면서 이 의례공간은 축소되어 외측 해자의 성문은 철거되었다. 그리고 내측 해자의 성문 중 9개소가 남겨졌으며, 이 공간이 오늘날의 ‘황거’와 연결되어 있다. 그러나 이 공간이 무조건적으로 ‘황거’로 치환된 것은 아니었다. 첫째, 처음에는 황거와 관청가를 합쳐 ‘황성 皇城’으로 구상되었다. 그러나 결국 성의 가장 중핵에 해당되는 혼마루 本丸 부분에는 황거도 관청도 설치되지 않았다. 또 관청가의 용지로서 확보된 또 다른 공간도 관청으로 이용한 경우는 극히 일부분에 지나지 않았다. 그 결과 의례공간으로서의 광장이 확대, 재생되었다. 둘째, 에도시대에는 통행이 가능했던 북측 부분(北の丸·山吹)의 도로는 일시 개방되었으나, 천황을 지키는 근위연대의 주둔지 설치에 의해 ‘황성’에 흡수되어 통행이 폐쇄되었다. 이와 같이 근대의 ‘황성’은 천황가가 거주하는 ‘황거’ 이외의 기능도 가졌기 때문에 거대한 공간을 유지할 수 있었다. 제 2차 세계대전 후 일부는 공원으로 개방되었으나 여전히 ‘황거’는 거대한 공간으로서 도시의 중심을 점유하고 있다.

Globalization, Digitalization, and Renationalization: Some Reflections from Japanese Cases

Koichi Iwabuchi 연세대학교 영어영문학과 BK21 Plus 사업단 2019 Situations: Cultural Studies in the Asian Context Vol.12 No.1

Across the world, globalization processes have been significantlyactivating cross-border flows and promoting the interpenetration ofcapital, people, and media communication. The development of digitalcommunication technologies and social media with their affect-drivencapacities reinforce these tendencies. Globalization apparently disregardsnational borders and undermines exclusionary national identities bygenerating cultural mixing, hybridized identifications, transnationaldialogue, and cosmopolitan consciousness. Digital communicationtechnologies have further intensified mediated collectivities beyond andacross the nation, but these developments do not necessarily bring aboutthe weakening of national imaginations and nation-centered frameworks. In many parts of the world, we have been observing the resilience ofnational identity and the resurgence of nationalism. Globalizationand digitalization have promoted various modes of cross-borderconnection, exchange, and confrontation while at the same time newlyhighlighting the relevance of national borders. This paper will discusshow renationalization accompanies the progression of globalization anddigitalization and considers the role of digital media and traditionalmass media in the reproduction of the nation, referring to Japanese casesin which a growing concern with the promotion of national dignityand national interests has been engendering hate-driven jingoism andcommercialized nationalism.

EFFECT OF LOAD AND ANODE/CATHODE AREA RATIO ON WEAR OF Zr-ALLOY IN Na₂SO₄ SOLUTION

A. IWABUCHI,K. HOSOYA,K. ABE,T. SHIMIZU,S. S. KIM 한국트라이볼로지학회 2002 한국트라이볼로지학회 학술대회 Vol.2002 No.10

In this paper we examined the contribution of mechanical and electrochemical factors in corrosive wear for Zr-alloy against Al₂O₃ ball in Na₂SO₄ solution. Normal load and the area of metallic specimen 'was varied to change the corrosion behavior. At the commence of sliding, the potential drop took place, which increased with load due to the great exposure of fresh surface. Wear volume was linearly proportional to load. The corrosion factor was about 15%. By increasing the Aa/Ac ratio, corrosion factor to total wear decreases and saturates above Aa/Ac=0.15.

동아시아의 경쟁과 디지털 미디어 그리고 일본의 근접한 적들

고이치 이와부치(Koichi Iwabuchi),김태균(번역자) 서울대학교 아시아연구소 2017 아시아리뷰 Vol.6 No.2

중국과 한국의 경제성장 사례에서 드러나는 것처럼, 전후 세계 자본주의의 팽창은 아시아 경제와 (상업화된) 문화의 부상을 가져왔다. 반면, 지난 20여 년간 일본사회는 소위 거품경제의 붕괴 이후 경제침체를 극복하기 위해 악전고투해왔다. 일본의 미디어 문화가 세계적으로 호응이 높아지면서 일본의 문화적 힘이 증가해왔다. 하지만 자본주의의 등장과 문화시장의 팽창은 아시아 국가들의 문화시장의 생산력을 증가시켰고, 특히 한국의 문화시장은 일본을 능가하는 수준에 이르렀다. 우리는 일본, 중국, 한국의 경제적이고 문화적인 경쟁관계가 지속적으로 심화되고 있음을 목격하고 있다. 이러한 경쟁관계는 역사적 문제들에 대한 정치적 갈등과 함께 나타나고 있다. 이 글은 1990년 중반 이후 미디어 문화의 동아시아 지역 내순환 및 소비의 활성화로 문화적 교류기 상당한 수준으로 진전되었음에도 불구하고, 어떻게 일본에서의 증가하는 반중, 반한 감정이 (반한 감정의 증가는 재일한국인들에 대한 혐오연설을 야기하기도 한다) 동아시아의 문화적 교류를 억제하고, 최소한 이것을 압도하게 되는지를 논의한다. 이 글은 동아시아 내의 경쟁관계의 증대가 일본의 상대적인 쇠퇴, 사회경제적인 막연한 좌절감, 그리고 디지털 미디어 커뮤니케이션의 급증과 복잡하게 얽혀서 혐오 표현의 대상으로서 근접한 적에 대한 공격과 추격을 형성해왔음을 주장한다. The substantial expansion of global capitalism in the post-Cold War context has accompanied the ascent of Asian economies and (commercialized) cultures as mostly exemplified by China and South Korea. In contrast, Japan’s experience has been marked by struggles with economic slump after the collapse of the so-called bubble economy. Nonetheless, Japan’s cultural power has been growing as Japanese media culture has been received favorably internationally. However, the advent of capitalism and the expansion of cultural markets have enhanced the production capacity of other Asian countries as well and South Korean counterparts have even surpassed those of Japan. Accordingly, we have observed the intensification of economic and cultural rivalry between Japan, China and South Korea and the rise of inter-Asian antagonism and the “othering,” joined by political contestation over historical issues. This paper discusses how the rise of anti-Chinese and Korean sentiments in Japan, which also generates hate-speech movements against resident Koreans, overwhelm, if not suppress, East Asian cultural exchange. This is considered within the social context of regional circulation and consumption of media cultures which has considerably advanced East Asian cultural exchange since mid-1990s. It will be argued that growing East Asian rivalry with the relative decline of Japan, the vague sense of socio-economic frustration, and the upsurge of digital media communication have been complicatedly conjoined to engender the attacks and search for proximate enemies as the object of animosity.

DEPENDENCE OF FRETTING WEAR ON AMBIENT PRESSURE

Asanome Shizu,Iwabuchi, Akira,Shimizu, Tomoharu ENGINEERING TRIBOLOGY RESEARCH INSTITUTE KYUNGPOOK 1998 INTERNATIONAL SYMPOSIUM ON HIGH PERFORMANCE OF TRI Vol.1998 No.-

In this paper the dependence of ambient pressure on the friction and wear of SUS304 stainless steel during fretting at room temperature was investigated. The ambient pressure was varied from 10 to 10 Pa. The experiment was carried out under the following conditions; normal loads of 0.6, 1.0 and 1.8 N, slip amplitudes of 10, 50, and 100 μm, a frequency of 10 Hz and the number of fretting cycles of 105. The friction and wear behaviors were affected by the pressure. In order to examine the formation and separation/removal of the compacted oxide layer in detail, the experiment was carried out in which ambient pressure was changed alternately from 10 Pa to 10 Pa during frettiong. From the change in coefficient of friction, it was found that the removal and formation rates of the oxide were more affected by normal load than slip amplotude, and more changeble at light load than those at higher load.
