Korea exported automobile components worth 23.09 billion dollars accounting for 4.2% of the total export amount(555.21 billion dollars) to the overseas during the past 2011. As a result, Korean recorded a trade surplus of 17.25 billion dollars corresponding to 56% of the total trade surplus 30.8 billion dollars. This study aims to analyze the competitiveness index and trend of automobile components toward the world and Japan and the dependence of automobile components on Japan by focusing on 31 items of HSK 10 unit among the domestic automobile components. In addition, this study proceeded with a deep research on specific items(gearbox). This analysis is very effective for grasping the weakness of domestic automobile component industry toward Japan and the specific situations such as which item causes a competitiveness problem toward Japan and how its characteristics are. As a result of analysis, automobile components have never recorded a surplus in a trade with Japan. Especially, as a result of picking 10 biggest import items of domestic automobile components, ‘gearboxes and their components(8708-40-0000)’ are listed as the 1st rank in a overwhelming scale toward both the world and Japan. In addition, the dependence of this item on Japan was 57.8% as of 2011, which was very high. Moreover, the competitiveness index toward Japan was -0.95, which was very low. It could be confirmed that it was inevitable to improve the trade balance of this item in order to solve the adverse condition of component industry toward Japan.
A Study on Versatile Chair Design Reflecting Users’ Behavior
김광희,최경란,성윤정 한국가구학회 2011 한국가구학회지 Vol.22 No.3
This study is to suggest versatile chair designs that are organically shaped to take individual orientation. This study intends to provide design method to ensure the face of the chair that contacts the body of its user is transformed flexibly to support the body. The movement of human body is not just a behavior but the ways and tools that reflexively express against external stimuli that are sensed and identified by the person. The versatile chair whose users’ sitting position is fixed is made by covering the lump form with a piece of cloth ensuring that the content is firmly fixed and by placing the beads-woven wood fabric according to the shape. And then, it is covered with the external cover. The proposed versatile chair designs assume specific forms as follows: First, it is a versatile chair whose user’s sitting position can fix. The organically-shaped form that can accept varying postures is made as a mass, which changes into different shapes when human body touches the form so that users can lie down or sit. Due to such transformation, body posture is determined and individual differences in shape changing are all acceptable. Second, it is a versatile chair that reflects the user’s position in a fixed chair, where a cloth-wrapper feature is applied to the form a sifit wrapped postures so that a variety of body postures can be accepted. Finally, a versatile chair that reflects the user’s position by changing the shape of is covered with forms so that it will be transformed and used in accordance with situations and chair shapes and reflect multiple shapes including round or square ones.
Electronic Transport Through Single-molecule Magnets in the Presence of an Acoustic Wave
김광희 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.61
Employing the Fermi golden rule and the rotating wave approximation, we calculate the electrical conductivity through a single-molecule magnet (SMM) coupled to the electrodes in the presence of the acoustic wave. We show that the sound wave can generate quantum beats of the conductance around the resonant field. The oscillatory behavior of the conductance depends on different resonances and the sweeping field’s speed.
