Abstract: The present invention relates to a Bacillus subtilis JCK-1398 strain (Accession No. KCTC 14084BP) having induced resistance activity in pine trees and various plants, a pesticidal or antibacterial composition comprising same as an active ingredient, a composition for controlling plant diseases or pests, and a control method using same. The Bacillus subtilis JCK-1398 strain of the present invention was experimentally confirmed to have control activity against pests, nematodes, and fungi, which cause various plant diseases, by inducing resistance in a host. Thus, the Bacillus subtilis JCK-1398 strain of the present invention can be effectively used to control related plant diseases and can be spread over a wide area through foliar spraying, and therefore is expected to be able to prevent the spread of pine wilt disease at low cost.

Abstract: In a refrigerator using a evaporator, and particularly in an apparatus and a method for controlling a refrigerating cycle of a refrigerator which is capable of easily switching a three-way stepping motor valve, by adjusting a flow of a refrigerant in a refrigerating cycle by using a three-way stepping motor valve, noise occurred in the conventional valve switching can be reduced, a power consumption of a three-way stepping motor valve can be reduced.
