A car's auto-transmission system consists of torque converter, pump, and fluid line where working oil flows, oil cooler. When operating temperature increase, the viscosity of working fluid decreases. This result not enough transport power to the auto-transmission, as well as have an effect on useful life of component and change of material properties. This experimental study was conducted to investigate thermal performance and pressure drop of double pipe type hydraulic oil cooler, which were influenced by height and pitch of inner fin, louver pitch, and internal diameter of pipe, length of heated section. The purpose of this study is to find optimal design parameters and to develop a high performance oil cooler of auto-transmission system.
한ㆍ아르헨티나 관계 - 발전의 가능성을 현실로 만들어가는 여정 -
장명수 ( Jang Myung-soo ) 한국외교협회 2021 외교 Vol.137 No.0
우리나라는 지구 정반대편에 위치한 먼 나라 아르헨티나와 1962년 외교관계 수립에 이어 1960년대 중반에 시작된 영농이민을 통해 관계가 본격화되기 시작하였다. 현재 약 2만 5천여 명에 달하는 우리 동포들은 이민 초창기 직면했던 많은 어려움을 근면과 성실함으로 이겨내고 아르헨티나에 건실하게 정착하였다. 우리 동포사회는 지난해 코로나19의 와중에서도 모금을 통해 사정이 어려운 우리 동포들과 현지 사회를 지원함으로써 동포애의 모범과 성숙한 한인사회의 모습을 보여주기도 하였다. 우리나라와 아르헨티나는 전통적인 우호 협력관계를 유지하고 있고, 특히 2004년 노무현 대통령의 아르헨티나 방문 시 “21세기 공동번영을 위한 포괄적 협력관계”를 구축하여 호혜적인 협력관계 발전을 위해 노력하고 있다. 아르헨티나는 지속적인 외환시장 불안과 고율의 인플레이션, 빈곤문제 등으로 어려움을 겪고 있는데 그 원인이 페로니즘 때문이라고 주장하는 사람들도 많이 있으나 페로니즘에 대한 평가는 보는 사람의 시각에 따라 매우 다르다고 할 수 있다. 우리나라는 현재 아르헨티나를 포함한 남미공동시장(MERCOSUR)과 무역협정 협상을 추진 중인데 조속히 타결되어 상호 투자와 교역이 더욱 활성화될 수 있기를 기대하고 있다. 광활한 국토에서 생산되는 막대한 농축산물, 엄청난 광물자원과 해양자원 그리고 원자력과 제약 등 다양한 분야에서 선진 기술을 보유하고 있는 아르헨티나와의 협력 가능 분야는 무궁무진하다. 앞으로 그 가능성을 실제 프로젝트로 현실화하기 위해 양국 정부와 민간의 부단한 노력이 필요하다고 할 것이다. Although Korea has established its diplomatic relations with Argentina in 1962, it was not until the Korean agricultural immigration to Argentina in the mid-1960s to deepen the bilateral relations. Overcoming the difficulties in the early years of immigration, the Korean community has settled down successfully in Argentina. The friendly and cooperative relations between Korea and Argentina were highlighted by the establishment of the “Comprehensive Partnership for the Common Prosperity toward the 21st Century”, agreed between President Roh Moo-hyun and President Nestor Kirchiner in 2004. Argentina is facing economic difficulties such as volatile foreign exchange market, foreign debt, high rate of inflation and poverty. But it has also a great potential with its vast agricultural capacity, natural resources and advanced technologies. The Korea - MERCOSUR Trade Agreement, currently under negotiations, is expected to bring new opportunities in promoting trade and investment between Korea and the MERCOSUR. It is up to the entrepreneurs and governments of Korea and Argentina to seek practical ways to turn potential into reality.

PURPOSE: This study was conducted to analyze the effects of virtual reality inspiratory muscle training and conventional inspiratory muscle training on diaphragm movement and pulmonary function in patients with thoracic restriction. METHODS: This study measured diaphragm movement, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and thoracic mobility (upper, middle, and lower trunk) under two different conditions. Forty young women between 19 and 24 years of age who had no history of orthopedic symptoms for the last 6 months were divided into experimental and control groups. The experimental group performed virtual reality inspiratory muscle training and diaphragm breathing, and the control group performed conventional inspiratory muscle training and diaphragm breathing. RESULTS: The control group showed a significant increase in all dependent variables except for lower trunk mobility and PEF. The experimental group showed a significant increase in all dependent variables except for lower trunk mobility. Particularly, the experimental group showed significant increases in diaphragm movement (p<.05), FVC (p<.05), FEV1 (p<.05), and PEF (p<.05) relative to the control group. CONCLUSION: We recommend inspiratory muscle training with a virtual reality program over conventional training to improve diaphragm movement and pulmonary function in patients with thoracic restriction.
유량향상을 위한 차량공조 부품의 배치 최적화에 관한 연구

Technology for automotive oriented environment is intensively developed in the field of high efficiency and economic vehicle. Otherwise the function of a vehicle is extreme1y improved and the number of component satisfies the requirement increases in an engine-room. This investigation is looking for optimal arrangements of CRFM components such as heat exchange, condenser, and cooling fan. Enhanced flow rate in the system is obtained by the present proposed layout for the core component.
