Abstract: Provided is a backward motion control technology for a car. The car comprises a backward-motion control terminal, a control signal converter, and a backward-motion controller. The backward-motion control terminal outputs a first backward-motion control signal corresponding to a backward velocity and a backward direction of the last trailer according to a user's operation. The control signal converter converts the first backward-motion control signal to a second backward-motion control signal which corresponds to a backward velocity and a backward direction of the car. The backward-motion controller controls the car based on the second backward-motion control signal so that the last trailer moves backward by the backward velocity and the backward direction corresponding to the first backward-motion controlling signal.

Abstract: A cell tube for ex vivo culturing animal cells and a multiple roller tube cell culture system are disclosed. Suitable for use in culturing cells, the tube has at its opposite end walls two openings through which culture media can come in and out. The openings are eccentrically located at corresponding positions in contact with the edge sides of the end walls. The system has a plurality of roller drums on which a multitude of cell tubes are assembled. As the roller drums are rotated, cells adhering to each tube experience a nutrient-rich state and aerobic starvation, repeatedly. In the nutrient-rich state, the cells are grown flourishingly. When subjected to starvation, cells select metabolism pathways for utilizing carbon sources effectively, produce lactate at a low rate and can maintain a constant pH, because they are in direct contact with air. The system makes cells adhere to the wall of cell tubes and provides air directly to cell surfaces. Adherent cells can be grown with normal morphology at high yield for a long time in the cell culture system. The cell culture can be easily scaled up simply by increasing the number of the roller drums. The system can exchange media and feed a gas mixture of oxygen and carbon dioxide easily, thus providing optimal environments suitable for small to large scale cell culture.

Abstract translation: 公开了用于离体培养动物细胞的细胞管和多辊管细胞培养系统。 适合用于培养细胞，该管在其相对端壁具有两个开口，培养基可通过这些开口进出。 开口偏心地位于与端壁的边缘侧接触的相应位置处。 该系统具有多个滚筒，多个细胞管组装在该滚筒上。 随着滚筒的旋转，粘附在每个管上的细胞反复出现营养丰富的状态和有氧饥饿。 在营养丰富的状态下，细胞生长旺盛。 当受到饥饿时，细胞选择有效利用碳源的代谢途径，以低的速率生产乳酸盐，并且由于它们与空气直接接触而能保持恒定的pH。 该系统使细胞粘附到细胞管壁上，并将空气直接提供给细胞表面。 粘附细胞可以在细胞培养系统中长时间以高产率以正常形态生长。 通过增加滚筒的数量，可以容易地放大细胞培养物。 该系统可以容易地交换介质并供给氧气和二氧化碳的气体混合物，从而提供适合于小型至大规模细胞培养的最佳环境。

Abstract: A method and an apparatus which permits intuitive management of a variety of digital contents stored in a mobile device. In a method for managing the contents, the mobile device determines a type of the content when a play of the content is ended. If the content is digital rights management (DRM) content, the mobile device checks a license count for authorized access to the DRM content and then determines whether or the license has expired or will expire shortly. If the license has expired, the mobile device removes the license-expired DRM content, or alternatively transfers the license-expired DRM content to a specified folder.
