An analytical process was suggested to evaluate the performance of mount system of fuel cell cars. To obtain demand capacities, the system analysis was conducted. Performance of rubber mount part was predicted numerically by evaluating the stiffness. The other part, bracket part was analysed to evaluate vibration characteristics, strength and durability. Through these analyses, the mounts and brackets have been designed and its performance has been also investigated.

본 연구는 운동을 포기한 시설 청소년을 대상으로 운동중도포기 과정과 운동중도포기에 따른 사회 심리적 상황을 기술적으로 서술하는데 그 목적을 두고 있다. 본 연구는 운동선수 경력이 있는 시설 청소년 3명을 대상으로 심층면담, 서술관찰, 문서자료 등을 사용하여 자료수집을 하였다. 본 연구의 결과 시설청소년의 운동중도포기 요인으로는 장래의 불확실성, 경제적인 부담, 부당한 교우관계, 정서적 지지의 결여로 인해 낮은 자아존중감으로 나타났다. 과도한 훈련상황이 시설청소년의 운동중도포기요인에 별다른 영향을 미치지 못했다. 경제적인 부담이 운동중도포기요인에 영향이 있는 것으로 나타났다. 이들은 운동부활동에 있어 필요한 대부분의 경비를 학교 측으로부터 지원받고 있다. 넷째, 정서적 지지의 결여로 인한 낮은 자아존중감이 운동중도포기요인에 큰 영향을 미치는 것으로 나타났다. 일반 청소년에 비해 시설청소년의 낮은 자아존중감은 이러한 역할모델의 결여로 인한 낮은 성취동기에 밀접한 영향을 보인다고 할 수 있다. 다섯째, 일반 청소년과 달리 부모의 역할모델을 경험하지 못한 시설청소년은 위기 갈등상황을 함께 고민하고 해결책을 마련해 줄 수 있는 멘토가 필요하다. 하지만 이런 멘토의 부재는 이들이 위기갈등 상황에서 대부분 현실과 타협하고 쉽게 운동포기를 선택하게 만드는 결과를 초래한다. The following study was conducted on social welfare facility youth athletes who discontinued further advancement in becoming a professional athlete. It is focused on technically describing the process of young athletes' mid-way give up and their social psychological status during the process of decision making. The following study was conducted by gathering data by in-depth interviews, descriptive surveys, documents and etc. of 3 social welfare facility youth athletes whom all have planned to become a professional athlete. The research summary are as follows the main factors of discontinuing further advancement of becoming a professional athlete are uncertainty of future, economic challenges, unjust treatment amongst peers, and low self esteem due to the lack of emotional support. Excessive training did not play an important role as one of the factors of giving up sports. Economic difficulties effected the decision making of giving up sports as a career. The athletes were supported most of their needed fees from their schools. Fourth, low self esteem due to the lack of emotional support was the greatest factor of giving up sports. Social welfare facility youth' low self esteem may be the result of lack of role models in comparison to general youth, and they are less driven for achievement of goals. Fifth, unlike general teenagers who have parents as role models to reach out to in times of difficulty, facility youth cannot turn to their parents for such support and therefore, need mentors to guide them through their troubles and crisis. But lack of such mentors makes teenagers vulnerable to compromise with reality when faced with a crisis, and eventually choose the easy way out by simply giving up sports and discontinuing efforts to become a professional athlete.

The demand to acquire and improve durability performance has steadily risen lately in rubber components design due to a demand for advanced emotional characteristics and the use of unitized or module components. In designing, an analytical estimation is the most effective way to improve endurance life. Existing methods of analytical estimation have mainly used a formula of endurance life obtained from fatigue test data. However, due to costs and time required for fatigue testing, as well as randomness of rubber materials, the rate at which such formula is used remains insignificant. In this paper, we describe endurance life estimation of an automotive motor mount using only the results from a relatively simple tearing test. For this, we performed tearing tests on natural rubber of various hardness used for manufacture of vibroisolating mount, and compared tearing factors in static and dynamic states. Also, using static deformation analysis and the tearing test data, we estimated endurance life of the motor mount and tested reliability of the proposed method by comparing the estimated values with actual test results.

Ubi-Home 환경에서 장치제어를 하기위해 다양한 방법이 제안되었다. 그 중 원격지에서 장치제어를 하기 위해 특정 기기(로봇)를 활용할 수 있다. 하지만 이와 같은 방법에는 로봇과 장치들의 위치인식과 이동경로 설정에 따른 제약사항이 따른다. 또한 이러한 위치인식 및 이동에는 미리 작성된 하나의 맵이 사용되므로 새로운 환경의 변화나 확장에 적용할 수 없다. 따라서 본 논문에서는 로봇과 장비의 위치인식과 이동경로를 위한 학습형 맵 작성1)기법을 제안하며, 테스트를 위해 Atmega128v4 MCU와 AX-12+ Motor, AX-S1 Sensor, ZBS-200 Zigbee, CL-1L5/ 603LM Infrared Ray Sensor로 로봇을 제작하여 실내 환경 모형에서 테스트하였다.

A low control arm must be designed to endure various loads transmitted from driving. For safety evaluation of a low control arm, many evaluating methods have been conducted. Because analytical methods are very efficiency to reduce the development time and coast, those are normally adopted in the design process of the low control arm. However, almost analytical methods ignored effects of rubber bushes and ball joint which are used to connect between a low control arm and a frame. Behavior of bushes and ball joint were expressed by using spring element and realistic rotation condition. The yield load and deformation behavior of low control arm were predicted and those results were verified by comparing with the test results.
