In order to allow continued production of TIER3 industrial engine, have to meet the TIER4emission regulation standard which is due to come into effect on 2015. The main purpose of the development was to retain the relatively inexpensive and simple IDI engine based on TIER3 while improving hardware and adding software components that allow achievement of the phase-in TIER4 emission standards. For reduce harmful substance in exhaust gas, Metal Foam Filter is used which is more appropriate than DPF for industrial engine in that do not need active regeneration. Metal Foam Filter is advantageous in NO2 passive regeneration. Furthermore, It has less risk in filter clogging and prevent excessive fuel consumption. It could be proven that a concept with a comparably cost-effective base engine which does not utilize CRDI, along with an advanced aftertreatment control system, is capable to meet the Korea TIER4 2015- phase in emission standards.

일본 육상자위대의 조직 개편 현황과 전망

방준영 ( Bang Joonyoung ),조재관 ( Cho Jaekwan ) 한일군사문화학회 2018 한일군사문화연구 Vol.26 No.-

일본 육상자위대는 지난 2018년 3월 27일, ‘즉응 기동하는 육상방위력’을 목표로 ①지휘통제능력의 강화, ②기동전개능력의 강화, ③수륙양용기능의 정비, ④경계감시능력의 강화, 그리고 ⑤체제 개혁을 뒷받침하는 교육훈련연구본부체제의 충실의 다섯 가지 범주에 초점을 둔 조직개편을 단행했다. 이는 구체적인 국가나 지명이 명시되지는 않았지만, 해양진출을 강화하는 중국의 움직임에 대응하여 남서제도에서의 억지 및 대처를 염두에 두고, 유사시 전국에서 부대를 신속하게 전선으로 전개할 수 있는 태세를 갖추기 위한 조치라고 할 수 있다. 구체적으로 일본 육상자위대는 전국의 5개 방면대를 일원적으로 통솔하여 유사시 전국의 부대를 지휘·운용하는 ‘육상총대’와 더불어 일본판 해병대에 해당하는 ‘수륙기동단’을 창설하였고, ‘교육훈련연구본부’ 및 ‘정보학교’를 신설했다. 또한 제8사단과 제14여단을 ‘즉응기동연대’를 주력으로 하는 기동사단과 기동여단으로 각각 개편함과 동시에, 전차와 화포의 수량 삭감을 내세우고 있다. 여기에 남서제도에 대한 경계감시능력을 강화하기 위해 동 지역에 경비부대 및 미사일부대 배치를 완료 혹은 계획하고 있다. 이러한 ‘발족 이래 대개혁’으로 불릴만한 육상자위대의 대규모 조직개편의 향후 전망은 2018년 연말로 예정되어 있는 새로운 방위계획의 대강 책정과 함께 그 체제이행 계획이 분명해질 것이다. 이와 관련해서 지난 6월에 아베 수상에게 전달된 자민당 정무조사회가 정리한 제언에서는, 現 방위계획의 대강이 제시한 ‘통합기동방위력’을 대신하는 ‘다차원 횡단(크로스 도메인) 방위구상’을 제창하고 있다. 이를 바탕으로 예상하건데 향후 일본 자위대는 육·해·공 뿐만 아니라 우주, 사이버, 전자 등의 영역도 활용한 다차원 횡단적인 방위력을 통합운용의 관점에서 최적화된 형태로 정비함으로써 필요한 방위력을 질적으로나 양적으로나 확충하려 할 것이다. 역내 안보환경의 개선을 바라는 우리로서는 향후 이러한 육상자위대 체제 이행의 방향성을 제시하게 될 일본 방위정책 동향과 그 내용에 예의주시할 필요가 있다. On March 27, 2018, Japan’s GSDF carried out a reorganization aimed at “Dynamic Defense Force.” The focus of the reorganization is on strengthening command control, strengthening mobility, maintaining amphibious functions, strengthening Education and Training Research Headquarters supporting system reform. Although no specific country or geographical names were specified, the measure was taken to ensure that troops could be deployed quickly across the nation with deterrence and counter-measures in mind in response to China’s move to strengthen its maritime advance. Specifically, Japan’s GSDF established “Ground Component Command,” which commands and operates troops nationwide in case of emergency and created a “Amphibious Rapid Deployment Brigade,” which is equivalent to the Japanese Marine Corps with “Training Evaluation Research and Development Command,” and “Military Intelligence School.” In addition, while reducing the quantity of tanks and artillery, the 8th Division and 14th Brigade will be reorganized as the Rapid Deployment Div/Bd, which will focus on the “Rapid Deployment Regiment.” Also, the deployment of security forces and missile units in the region is completed or planned to strengthen the surveillance capability on the southwestern islands. The future prospects for the massive reorganization of the Self-Defense Forces, dubbed the Great Revolution since its inception, will be clear through the next new National Defense Program Guidelines(NDPG), scheduled for the end of 2018. In the proposal, which was delivered to Prime Minister Abe in June by the Policy Affairs Research Council in Liberal Democratic Party, “Cross Domain” defense initiative is being proposed to replace the “Dynamic Joint Defense Force” proposed by the present NDPG. Based on this, the Japanese Self-Defense Forces will seek to expand the necessary defense capabilities in terms of the combined operation of the multi-dimensional cross-section, utilizing not only land, sea, air but also space, cyberspace, electronics. As far as we hope to improve the security environment in the region, We need to pay close attention to Japan’s defense policy trends and their content, which will show the direction of implementation of the Self-Defense Forces system in the future.

中共의 對美和解政策

趙在瓘 건국대학교 1975 學術誌 Vol.19 No.1

There are many factors in the foreign policy decision-making of any country. The various factors may be classified into two categories, i. e., change and counstancy in a relative sense. The international environment of the group of decision-makers may belong to the former category, while the industrial capacity, military power, or resources to the latter. Among the factors of relatively constant, there is the geographical location of a country that plays a substantial role in the mind of the decision-makers. Viewed from this angle, the location of Communist China in relation to the Soviet Union and the United States attracts a great deal of attention when one tries to evaluate the decisive factors of the detente policy of China toward the United States of America. If China had no border with the Soviet Union, there would have been no such an accident as the crossing of the border by a Russian helicopter into the territory of China or would have been less or no direct and continous pressure from Moscow to Peking along with the borderline. China might have had no serious reason to interfere in the Korean war which occurred in 1950 if she had been located on the other part of the globe. Of course, in this age of supersonic jets, continental ballistic missiles, and other developed vehicles and means of communications, the importance of the geographical location has been declined. However, is it adequate or proper to ignore the importance of this factor in determining foregin policy of a country like Communist China? This question is the point of departure of this paper. Paying suffiicent attention to the fact that the constancy of the location of a country does not necessarily mean fixed functions of the location and that the source of variety of function has a lot of things to do with perception, judgment, and goals of the decision-makers, this paper dealt, first, with the fundamental goals of Communist China. It discusses the implications of the "theory of the third world" which was elaborated by Teng Hsiao-ping at the special meeting of the General Assembly of Nations on resources in April, 1974. The discussion will cover the difference between the "theory of intermediate belt" and that of the third world. Second, it tries to analyze the decisive factors of the detente policy of Communist China with regard to the United States, the Chinese perception of the border clash between Communist China and the Soviet Union in 1969, and the subsequent rapprochement of the two super-powers. As to the options open to the decision-makers of china with regard to detente, it points out that there were at least three choices. The first was to reconcile with the Soviet Union at the possible expense of national independence, the second was to seek thaw with the United States in spite of the potential resistance from within, and the third was to oppose both the super-powers at the same time. Up to the present moment, the Chinese leaders seem to have chosen the second option and have experienced the abortive coup d'e´tat by Lin Piao who opposed the reconciliation with the United States. The reason why Communist China preferred the second way to the first or the third apparently had a deep relationship with the fact that the United States was the sole power that was capable of deterring the Soviet Union from launching a surprise attack on China. Therefore, in the conclusion the paper states that one of the fundamental factors in the formulation and execution of foreign policy of Communist China is consideration of the presence of the Soviet Union that threatens, to the Chinese mind, security of Communist China by forming an encirclement or containment of China, which is intrinsically related to her geographical location.
