The present invention relates to a process for preparing a phenolic polymer using a phenothiazine-based mediator, in particular, to a process for preparing a phenolic polymer via polymerization of phenolic monomers by using a phenothiazine-based mediator in the presence of peroxidase biocatalyst and an oxidant, thereby drastically improving the enzyme reactivity of peroxidase. The phenolic polymers prepared according to the polymerization of this invention maintain unsaturated hydrocarbon groups linked to their side chains, so that they are very useful as a curing resin because they can easily form coatings through radical curing. In addition, the coating formed using the curing resin has an antioxidation effect and a low surface energy, so that they can prevent physical attachment of marine livings. Because the antifouling-causing functional groups are not consumed, the coatings continuously exhibit durability.

Provided are a method for time shift and a television receiver capable of preventing storage of a broadcasting stream by clearing a buffer when a broadcasting stream is not buffered for longer than a predetermined time during a time shifting operation. In the time shift method, a received broadcasting stream is buffered to a buffer, a time for which a broadcasting stream having the same identification information is received is counted, and the buffer is cleared when the counted time is less than a predetermined time. The television receiver includes a buffer, a storage unit, a signal detector, a timer, and a control unit. The buffer buffers a received broadcasting stream, the storage unit stores the broadcasting stream, and the signal detector extracts package identification information of the broadcasting stream. The timer counts a time for which the same package identification information is received, and the control unit clears the buffer when the counted time is less than a predetermined time.

A scene change detector algorithm in image sequence is disclosed, in which a two-stage detecting process is applied to perceive a scene change in a precise and safe way. The algorithm includes classifying images into two different states, a transition state and a stationary state, after determining whether there is any change in adjacent frames, and confirming the scene change by rechecking whether there is the scene change in the classified frames.

An oil supply apparatus for an engine includes an oil pan located beneath the engine to store oil therein, an oil pump mounted in the oil pan to pump the oil stored in the oil pan, and a chain-drive unit mounted between the oil pump and a crankshaft of the engine to transmit a rotating force of the crankshaft to the oil pump. The chain-drive unit is partially immersed in the oil stored in the oil pan. With this configuration, there is no need for separate elements for lubricating the chain-drive unit, whereby the overall structure of the oil supply apparatus can be simplified. This results in a reduction in the number of elements and manufacturing costs.

The present invention relates to providing mobility management protocol information to a multi-mode mobile terminal for performing handover between heterogeneous networks. Preferably, the present invention establishes a unified interface to an upper layer of the mobile terminal for managing messages to and from at least one of a homogeneous network and a heterogeneous network, establishes a connection with an accessible link of at least one of a homogeneous network and a heterogeneous network for performing handover, and receives in the upper layer information from the unified interface related to the established connection. Preferably, the step of receiving the information includes receiving mobility management protocol information of the at least one of a homogeneous network and a heterogeneous network. Accordingly, the mobile terminal reduces a time duration for establishing a Care of Address (CoA) using a new mobility management protocol of a new network the mobile terminal has been handed over to.
