A program execution and operation right management system capable of providing flexible and sufficient protection uniformly even for the thread operation instructions among the threads sharing the same virtual address space and/or for individual memory region. In the system, operation right data indicating which thread can be operated by which thread among a plurality of threads are stored, and whether a thread operation with respect to one thread requested by another thread among a plurality of threads is allowed by the operation right data is judged. Then, the processor is allowed to carry out said thread operation with respect to that one thread by that another thread only when it is judged that said thread operation is allowed by the operation right data.

Disclosed is a cell culture tube, having in opposite end walls two respective eccentric openings which communicate with each other through an inner straight passage formed in the cell culture tube, in which the inner straight passage is tilted at an angle relative to a longitudinal axis of the cell culture tube to allow a culture medium to smoothly flow into and out of the inner passage through the openings. Also, provided is a multiple cell culture system using a plurality of the culture tubes.

A refrigerator includes a fresh food compartment, a freezer compartment defined by inner walls and an outer case respectively, an insulation barrier separating the compartments, and doors for providing access to the compartments. A passageway is formed in the barrier for providing refrigerated air to the fresh food compartment. A connecting duct diverges from the passageway and extends forwardly towards the front portion of the fresh food compartment. A door duct communicating with the connecting duct when the door is closed is coupled to the door. As a result, the fresh food compartment and door-adjacent portions of the fresh food compartment are promptly and uniformly cooled.

A circle type LED lighting flood lamp using a nano spreader is provided, which can provide a double heat dissipation structure formed by mounting an extended nano spreader having high heat diffusion on the inside of a circular type upper cover and making the extension parts of the nano spreader in contact with a heat dissipation portion in both directions, and prevent a heat dissipation plate from exposing to an outside by fixedly putting the upper cover on the outside of a heat dissipation member to improve the heat dissipation efficiency and the life span of the lamp. The circle type LED lighting flood lamp using a nano spreader includes LEDs, an LED mounting substrate on which the LEDs are mounted, a nano spreader having one side that is in contact with the LED mounting substrate and the other side that is extended for a specified length to form extension parts, an upper cover having inner heat dissipation pins that are in contact with the extension parts of the nano spreader, an upper cap fixed to an upper end of the upper cover, a lower heat dissipation member inserted into the inside of the upper cover and having an inner surface that is in contact with the extension parts of the nano spreader and an outer surface that is in contact with an inner surface of the upper cover, and a lower lens fixed to a lower part of the lower heat dissipation member.
