The purpose of this paper is to explore the role of Keidanren, the major business organization of Japan, in shaping Japan's Defense Industrial Policy during the Cold War era. For this purpose three cases are examined using a comparative perspective: 1) the New Beginning of Arms Production; 2) the Fourth Defense Buildup Program; and, 3) the co-development of the F-2 fighter aircraft/FSX between Japan and the United States. These case studies yielded several findings. In the first case, the resurrection of arms production in Japan after World War II was led by Keidanren during the American occupation. Keidanren was able to rearm under favorable conditions because U.S. policy toward Japan was changed owing to the Communist takeover in China in 1949 and the Korean War in 1950. The second case showed that Keidanren was able to achieve its demands for indigenous defense production(Kokusanka) and long-term planning of a defense build-up program embodied in the Fourth Defense Buildup Program through the efforts of intermediate organization such as consultative bodies (shingikai) or other committees. Finally, in the study of the FSX, Keidanren made efforts to internalize Japan's defense industry and was to achieve good results. By negotiating a deal to co-develop the FSX, Keidanren was able to change the cooperative relationship between Japanese and U.S. defense industries to a more equal one. In conclusion, Keidanren played a key role in the development of the Japanese defense industry during the Cold War era.

동아시아 지역협력

김진기(Jinki Kim) 21세기정치학회 2006 21세기 정치학회보 Vol.16 No.1

This paper attempts to explain the recent stagnation of APEC or the other regionalism in East Asia in spite of the close economic interdependence. The most important thing is the US policy toward China on the global level. The Bush administrations' policy toward China is more aggressive compared with Clinton's and Japanese policy toward China is following the Bush administrations' policy. The strained relations between Japan and China is getting an obstacle to the East Asian regional cooperation or East Asian regionalism. The ostensible reasons of the confrontation between the two countries are the territorial dispute on the Senkaku Islands(Diaoyu Tai) and the understanding differences on the Japanese invasion during the second World War. However, the real reason comes from the China's fast economic growth and the growing economic weight in the world. As a result, the disparity of national power between the two countries is narrowing and the restructuring of regional order is going on. In this situation, the two countries are seeking for the real politics like the enhancement of nationalism and militarism in pursuit of superior position. To mitigate two countries' confrontation, multilateral frame of security sphere has to be constructed and the other agenda like the economic cooperation has to be activated. Furthermore, the development and practice of substantial program to enhance the community mind among Northeastern Countries has to be planned.

군수산업의 민수전환에 관한 비교 연구

김진기(Jinki Kim) 21세기정치학회 2003 21세기 정치학회보 Vol.13 No.1

In this paper I examine the defense industry policies the U.S., Russia, China and Japan in terms of conversion. Taken together, the defense industry policies of these countries are divided into two categories. One is defense specific industry policy which has represented the U.S. and Russia, and the other is dual technology policy which has represented Japan and China. With the waning of the Cold War, conversion has been a policy issue in the U.S. and Russia and a bundle of conversion programs have been adopted. However, the results of conversion in both countries are not satisfactory because of short-term economic interests in the U.S. and the general problems of economic transformation in Russia. On the other hand, conversion in Japan and China which has been a policy for a long period of time is proved to be successful. The success and failure of conversion in these countries come from the countries' security environments, economic capacity, the level of technology and so on. First, the defense technology and industrial base of the U.S. and Russia has been separated for a long time. As a result, it is very difficult for the two countries to convert defense industry to non-military industry for a short time. Second, China and Japan do not have enough economic materials to develop the military specific items.

아베 정권의 방위산업 · 기술기반 강화전략

김진기 ( Kim Jinki ) 국방대학교 안보문제연구소 2017 국방연구 Vol.60 No.2

이 논문의 목적은 아베 정권에서 이루어지고 있는 방위역량강화가 어떻게 전개되고 있는지를 살펴보는 데에 있다. 아베 정권 들어서 진행되었거나 추진되고 있는 안보정책의 전체적인 틀은 크게 두 가지 측면, 즉 정책적 측면과 산업·기술적 측면의 변화를 겨냥한 것으로 대별할 수 있다. 전자가 일본 방위정책의 의도를 나타내는 것이라면, 후자는 방위역량강화를 위한 것이다. 방위역량 강화를 위한 노력은 두가지 측면에서 전개되고 있다. 첫째, 방위산업의 역량을 강화시키기 위한 노력이다. 이는 방위장비이전 3원칙과 이를 뒷받침하기 위한 방위장비청의 설립으로 구체화되어 나타나고 있다. 둘째, 방위기술기반을 강화하기 위한 노력이다. 이는 전후 금지되어 왔던 대학에서의 군사연구를 위한 노력으로 구체화되어 나타나고 있다. 요컨대 아베 정권에서 추진되고 있는 안보정책은 단순히 정책상의 변화만을 겨냥하고 있는 것이 아니라 방위산업과 기술기반 등 안보역량을 강화하기 위한 제반 조치들도 함께 진행되고 있는 것이다. This paper purports to analyse the defense policy change of Abe administration. The defense policy change of Abe administration is composed of two parts. One is the defense policy which shows the intention of Japanese defense policy. The other is the defense capability strengthening plan which supports the defense policy. The defense capability strengthening plan is being developed by both the consolidation of defense technology and industrial base. The consolidation of defense industrial base has shaped as the 3 principles of defense equipment transfer and establishment of ATLA(Acquisition, Technology & Logistics Agency)`The strengthening of technology basse has appeared as cooperation and collaboration between universities, institutes and ATLA.

전후 일본을 보는 하나의 시각

김진기(Jinki Kim) 21세기정치학회 2001 21세기 정치학회보 Vol.11 No.1

본 논문의 목적은 전후 일본 정치엘리트들이 공유하고 있는 정치정향의 역사적 배경을 살펴보는 데에 그 목적이 있다. 이를 위하여 본 논문에서는 전전과 전후 일본의 지배구조가 어떠한 차이점이 있는지를 살펴보았다. 본 논문이 상정하고 있는 가설은 전전과 전후의 일본지배구조 사이에는 현상적인 변화에도 불구하고 본질적인 면에서는 변화가 없다는 것으로 요약될 수 있다. 이 가설을 뒷받침하기 위하여 필자는 세가지 측면에서 살펴보았다. 우선 전전 일본의 전체주의적 요소청산을 목표로 진행되었던 미국의 점령정책이 어떤 결과로 나타났는가에 대한 고찰이다. 두 번째는, 전후 일본 지배엘리트의 인적 구성과 제도적인 측면은 전전과 얼마나 차이를 보이며 이들이 공유하고 있었던 사상적 토대는 무엇인가에 대한 고찰이다. 마지막으로, 전후 일본의 주요정책이 전전의 정책과 어떠한 차별성을 가지고 있는가에 대한 고찰이다. 이러한 측면들에 대한 분석 결과는 본 논문의 가설을 뒷받침하는 것으로 나타났으며, 결과적으로 현대 일본엘리트들의 정치적 정향 또한 전전의 정치적 정향을 상당부분 온존시켜 왔다는 것을 알 수 있었다.

본 연구는 만 19세 이상 60세 미만 성인남녀 98명을 대상으로 스마트폰 앱인 Gene-Health을 이용하여 식사 기록을 통해 분석된 영양소섭취량과 동일한 날의 식사 섭취 전과 후의 사진비교를 통해 섭취량을 추정하여 분석된 영양소섭취량을 비교함으로 Gene-Health의 타당도를 조사하기 위해 수행되었다. 주요 결과는 다음과 같다. 첫째, Gene-Health의 영양소섭취량과 사진을 통해 추정한 영양소섭취량을 비교한 결과 에너지, 탄수화물, 지방, 지방으로부터의 에너지 섭취비율은 통계적으로 유의한 차이가 없었으나 단백질 섭취량과 단백질로부터의 에너지 섭취 비율은 Gene-Health가 높았고, 탄수화물로부터의 에너지 섭취비율은 사진추정군이 높았다. 둘째, Gene-Health와 사진을 통한 영양소섭취량의 상관성은 에너지, 탄수화물, 단백질, 지방섭취량과 탄수화물 비율, 단백질 비율, 지질 비율은 모두 상관계수 0.382–0.708로 유의적인 양의 상관관계를 보였다. 셋째, Gene-Health와 사진을 통한 에너지, 탄수화물, 단백질, 지방섭취량과 탄수화물 비율, 단백질 비율, 지질 비율의 가중 카파 계수는 0.588–0.662로 상당히 일치하는 경향을 보였다. 에너지와 다량영양소, 다량영양소 섭취비율의 same agreement는 41.8%–48.0%이며 adjacent agreement는 75.5%–88.8%였다. 본 연구를 통하여 Gene-Health는 에너지와 다량영양소 섭취량을 추정하기 위한 타당한 도구라고 사료된다. 추후 연구에서는 다양한 연령과 여성 참가자를 확대하여 성별과 연령에 따른 Gene-Health의 타당도를 연구할 필요가 있다. Purpose: This study was conducted to evaluate the validity of the Gene-Health application in terms of estimating energy and macronutrients. Methods: The subjects were 98 health adults participating in a weight-control intervention study. They recorded their diets in the Gene-Health application, took photographs before and after every meal on the same day, and uploaded them to the Gene-Health application. The amounts of foods and drinks consumed were estimated based on the photographs by trained experts, and the nutrient intakes were calculated using the CAN-Pro 5.0 program, which was named ‘Photo Estimation’. The energy and macronutrients estimated from the Gene-Health application were compared with those from a Photo Estimation. The mean differences in energy and macronutrient intakes between the two methods were compared using paired t-test. Results: The mean energy intakes of Gene-Health and Photo Estimation were 1,937.0 kcal and 1,928.3 kcal, respectively. There were no significant differences in intakes of energy, carbohydrate, fat, and energy from fat (%) between two methods. The protein intake and energy from protein (%) of the Gene-Health were higher than those from the Photo Estimation. The energy from carbohydrate (%) for the Photo Estimation was higher than that of the Gene-Health. The Pearson correlation coefficients, weighted Kappa coefficients, and adjacent agreements for energy and macronutrient intakes between the two methods ranged from 0.382 to 0.607, 0.588 to 0.649, and 79.6% to 86.7%, respectively. Conclusion: The Gene-Health application shows acceptable validity as a dietary intake assessment tool for energy and macronutrients. Further studies with female subjects and various age groups will be needed.

NaOCl 처리 농도 및 시간에 따른 희귀식물 자란(Bletilla striata Rchb.f.)의 종자 발아 및 활력 연구

정영호,김진기,이하얀,송세규,배기화,Jung, Young Ho,Kim, Jinki,Lee, Hayan,Song, Se-kyu,Bae, Kee Hwa 한국식물생명공학회 2020 식물생명공학회지 Vol.47 No.1

This study was conducted to examine the vitality of Bletilla striata Rchb.f. seed treated with different concentrations sodium hypochlorite (NaOCl) for different lengths of time. This study also examined the effect of NaOCl treatment times and concentrations on swelling formation and seed germination of B. striata seed. The non-treated B. striata seed had the highest survival rate (82.7%) Treatment with more than 1.5% NaOCl negatively affected the seed survival rate, as compared to concentrations of less than 1%. The swelling formation and seed germination percentages were highest (90.1% and 94.1%, respectively) when seeds were treated with 0.5% NaOCl for 20 min. These results can be used as important basic data for the growth and restoration of B. striata and further suggest the possibility of individual restoration in habitats.

[차량운동성능부문] 승차감 향상과 저 에너지 소비를 위한 새로운 능동현가장치의 구조 제안

전재춘(Jaechoon Chon),김진기(Jinki Kim),한진욱(Jinwook Han),김경욱(Jyung-Ok Kim) 한국자동차공학회 2001 한국자동차공학회 춘 추계 학술대회 논문집 Vol.2001 No.11_2

This paper presents a new design of actuator of active suspension system for low energy consumption and good ride comfort. This new active system is designed to have desirable features of the Full Bandwidth Active Suspension System (FBASS) and the Slow Active Suspension System (SASS). The system thus provides low energy consumption with electro-hydraulic system and good ride comport with electro-hydraulic and pneumatic systems. The actuators of the proposed system are composed of two parts. The upper part having double acting cylinder provides the FBASS functionality and the lower part with single acting cylinder supports the vehicle body along with the coil spring and provides the SASS functionality. Stiffness of the coil spring used in the structure equals that of the coil spring used in SASS. By applying the hydraulic pressure to both the upper and the lower parts of the actuator, the resulting pressure will be about half of the hydraulic pressure in SASS. This will result in reduction of energy consumption that is one of the main issues of the existing structures. However, in order to achieve this low energy consumption for the proposed active suspension system (ASS), we need to increase the size of the accumulator for storing the temporal flux supplied by the hydraulic pump at the descent of the vehicle body.
