Dual Clutch Transmissions (DCT) are becoming more and more used as an improving add-on solution on manual and automated manual transmission systems. The key issues in dry clutch control is launch and shift control. Dry clutch control is so difficult due to variation of clutch transfer torque characteristic as varying factors. This paper is proposed launch control using Two-stage slip control and implemented to real vehicle with installed DCT.

This article presents the reduction of vibration generated by an automobile fuel pump. In order to analysis the vibration of the fuel pump, a simplified dynamic model is established, which is composed of a rigid rotor and a equivalent springs. The equivalent stiffnesses of the upper and lower assemblies are evaluated by the comparison of modal testing results and the finite element analysis. the stiffness for the oil film of the journal bearing is extracted by using Reynolds equation. In addition, the time responses for the vibration of the vibration of the fuel pump are computed by using a commercial multi-body dynamics software, RecurDyn. Based on these results, some design suggestions are proposed to reduce the vibration of an automobile fuel pump.

최근 기상정보를 활용한 사업영역이 확대되면서 고품질 관측 자료를 위한 위성의 수 역시 증가하였다. 현대의 위성산업에서 우위를 점하기 위한 전략에는 기존 방식을 더욱 발전시켜 성능이 향상된 고성능 위성을 이용하거나 다수의 위성을 이용하여 시간해상도를 향상시키는 방법이 있다. 또한 이미 국내 산업계가 충분히 가지고 있는 중소형 위성체 기술을 적극 활용하여 저궤도 기상위성을 개발한다면 비용과 위험은 낮추면서도 높은 성능의 독자 기성위성을 확보할 수 있다. 이와 함께 탑재체 기술을 국산화하기 위한 노력이 병행된다면 국내 위성 산업체의 경쟁력 향상과 과학기술 수준의 향상을 함께 추진할 수 있을 것이다.

스테레오 비전 시스템에서 전통적인 매칭 알고리즘으로 SAD(Sum of Absolute Differences), SSD(Sum of Squared Differences), NCC(Normalized Cross Correlation) 등 다양한 알고리즘이 존재한다. 그러나 하드웨어로 실시간 처리를 위한 시스템을 구현하기 위해서는 리소스가 한정 되어있다는 제약 때문에 많은 연구에서 SAD 혹은 RT(Rank Transform), CT(Census Transform)를 많이 사용하게 된다. FPGA 내부에는 BRAM(Block RAM)과 MAC(multiply-accumulator)인 DSP슬라이스가 이미 존재한다. 본 논문에서는 BRAM과 DSP로직을 활용해서 전통적인 매칭 알고리즘 중에서 연산기 사용이 가장 많은 NCC를 FPGA로 실시간 처리 가능한 하드웨어 구조를 제안한다.

각각의 분산전원 시스템은 등가회로를 이용하여 수학적으로 모델링하고, 이를 결합하여 제어 가능한 하이브리드 시스템을 모델링하였다. 시뮬레이션과 실험 결과로부터, 본 논문이 제안한 인버터 제어 알고리즘을 이용하면 분산 전원의 출력을 안정적으로 운영 할 수 있고, 효율적으로 부하관리를 할 수 있어 계통 운영을 여유롭게 할 수 있었다. 이러한 연구는 출력 변동으로 인해 마이크로 그리드 내 설치가 어려운 제어 불가능한 전원인 태양광 발전의 설치용량 확대를 가져올 수 있을 것이다.

동유럽사건과 1950년대 일본사상계의 전환 -아베 고보 『동유럽을 가다』를 중심으로-

安部工房『東歐を行く』は1955∼58年のいわゆる「社會主義下における矛盾論爭」の最中で刊行された。矛盾こそ發展の原動力と見なしてきた唯物弁證法に從えば、社會主義社會ではいわゆる階級的矛盾が解消されたため、もはや發展どころか沈滯の道を道を천るしかなくなる。フルシチョフのスタ一リン批判とともに、この逆說的な構造をめぐる論爭こそ、スタ一リンによって公式化された「弁證法的唯物論」という世界觀に決定的な龜裂をもたらした。この問題について共産圈の內部からも矛盾對立が常在すると主張し、從來の弁證法的な敎條を守ろうとした保守派と、矛盾の志向や統一が發展の原動力と見なし「統一·團結·一致」を發展の原動力を唱える官學派との對立があった。安部工房の場合、社會主義社會の內部における資本主義的な矛盾に注目する保守派とも、矛盾そのものを發展の支障と見なす官學派とも異なる意見を東ヨ一ロッパでの體驗を元に披露する。安部は資本主義的な矛盾をマイナス的な矛盾だとし、大衆たちの創意的自發的なエネルギ一をプラス矛盾の要因だと規定する。そして、このプラス矛盾は、民族的な外觀をまとい、國際的で普遍的な社會主義を以てその內容とすると披瀝した。 Abe Kobo’s I go the Eastern Europe was published in the middle of the so-called ‘conflict controversy in socialism under’ in the 1955-58. According to the materialist dialectic, contradiction has been regarded as the only driving force of development. Since the so-called class contradictions in socialistic sate has been eliminated, socialistic state will not be able to be developed, and follow the road of stagnation. Not only Khrushchev’s Stalin criticism, but also controversy over this paradoxical structure resulted in a decisive crack in the view of the world that has been formulated ‘dialectical materialism’ by Stalin. It claimed that on this issue is a conflict confrontation also from the inside of the communist bloc to the resident, and the traditional dialectical conservatives were trying to protect the doctrinaire, is oriented and unity of contradictions regarded as a driving force behind the development of "unity, solidarity-match" there was a confrontation between Kangaku school recite the motive force of development. In the case of Abe Kobo, society in the interior of the society both conservatives to focus on the capitalist contradictions, to show off a different opinion also Kangaku faction regarded the conflict itself and the difficulty of development based on the experience in Eastern Europe. Abe is the capitalist contradiction that it is minus contradictions, to define a creative spontaneous energy of the masses who with a factor of plus contradiction. And, this plus contradiction, wearing the ethnic appearance, was Hireki to and its contents Womotte international universal socialism.

As cities increase in density, more land is used for residential areas and existing green space is lost. The result is increased investment in establishing parks. As the concept of "well-being" has increased in popularity, more and more time and money have been invested in creating open spaces and the number of people enjoying those spaces, including hikers, has in turn increased. More hikers have led to damage from excessive use to urban parks and trails including in places like Bukhansan National Park in Seou, and Palgongsan Provincial Park and Apsan Park in Daegu. Many Daegu citizens often visit to Palgongsan Provincial Park and Apsan Park. However, there not enough research has been done on user-behavior or satisfaction with forested parks and open spaces in these cities. Therefore, this research collected data related to user-behavior through a questionnaire targeting Apsan Park, a representative forested park in Daegu, and analyzed present conditions, user-behavior, and the relationship between satisfaction-achievement. Then, the survey was analyzed to know user-behavior or satisfaction for providing basic information on plan·design·management of urban forested parks. The results are as follows. People usually visit the forested parks with family, friends, or alone for exercise or relaxation. Most visitors come once or twice a week from 9 a.m. to 6 p.m. on weekends and spend two to four hours there each visit. The most-used facilities in the park were trails and sports facilities, reflecting survey results that said most visitors use the park for exercising and walking. and exercising. Therefore, program and facilities managers should take these numbers into consideration. Respondents wanted more trees, lawns and flowers. Also facilities should be kept in a good state of repair and rest areas should be expanded. According to the analysis of the importance-achievement, respondents expressed dissatisfaction to conditions related to restrooms, garbage disposal, and damage to natural resources and cultural amenities. Visitors also wished to see more development of walking areas. To raise user-satisfaction from forested parks, management of land, facilities, nature resources, and cultural amenities should be considered to prevent environmental damage. Facilities and rest areas should be expanded including more trees, lawns and flowers. With more information, improvements, more active participation in forested can be expected.
