The present invention relates to a method for braze-welding a fixing plate and a flow channel cap in a heat exchanger, and to a heat exchanger produced by same. The method includes: providing a fixing plate 10 having a plurality of resilient protrusions 11 for snap-fitting; providing a flow channel cap 20, one end 22 of which is L-shaped to be snap-fitted onto the resilient protrusion 11 and the other end of which has a stepped portion 21; inserting the stepped portion 21 of the flow channel cap 20 into the resilient protrusion 11 such that an end 21b of the stepped portion 21 contacts an end of the resilient protrusion 11; pressing the L-shaped end 22 of the flow channel cap 20 against the resilient protrusion 11 of the fixing plate 10 such that the L-shaped end 22 is snap-fitted onto the resilient protrusion 11 and thus tightly contacts the fixing plate 10, and the resilient protrusion 11 thus press-contacts the end 21b of the stepped portion 21 to enable an end 21a of the stepped portion 21 to tightly contact the fixing plate 10; and braze-welding the fixing plate 10 and the flow channel cap 20. The above-described method eliminates a spot-welding process which might otherwise be performed prior to the process of braze-welding the fixing plate and the flow channel cap in conventional heat exchangers, to thereby reduce manufacturing costs and labor and to improve productivity.

The preset invention relates to a heat exchanger in which heat transfer between heating water passing through the inside of heat exchanging pipes and combustion gas is efficiently performed. The heat exchanger includes: a plurality of heat exchanging pipes, each of which has an end with an open flat tube-type cross-sectional surface, and through the inside of each of which heating water passes; a first fixing plate and a second fixing plate, each of which has pipe insertion holes formed at a predetermined spacing in the lengthwise direction of the plate, such that both ends of the plurality of heat exchanging pipes are inserted into the respective pipe insertion holes; a first parallel flow channel cap and a second parallel flow channel cap fixed at the respective first fixing plate and second fixing plate to close both ends of the heat exchanging pipes and thus form a parallel flow channel; a heating water inlet connected to the first parallel flow channel cap; and a heating water outlet connected to either the first or second parallel flow channel caps. The cross-section of each of the heat exchanging pipes has protrusions and recessions alternately arranged in the width direction of the heat exchanging pipe, so as to extend the flow path of the combustion gas passing through between the heat exchanging pipes.

Disclosed is a golf swing training apparatus, which allows a user to learn a stable swing motion by acquiring a correct swing posture in performing a swing motion and to train turning motion of his/her shoulder and a rotating motion of his/her waist in a natural manner. The golf swing training apparatus includes: a body 10, which is arranged between both arms when a user takes an address posture, and has a reverse trapezoid-shape corresponding to a shape formed by the arms; arm supporting parts 12, which are arranged at both side surfaces of the body 10, respectively, the surfaces facing each other, and have an open part, which is opened outward, so as to allow both arms to be seated on and supported by the arm supporting parts in an unfolded state of the arms; and arm holders 14 for covering the open parts of the arm supporting parts 12, respectively, so as to control change of a shape formed by the arms, such as widening of an interval between the arms, bending of arms respective to each elbow, etc. The golf swing training apparatus controls changes in shapes of both arms, such as the interval between the arms becomes widened, bending of elbows, etc. when a golfer performs a swing motion in a swing training so as to guide his/her shoulder and waist to be smoothly turned. As a result, the golfer can learn a stable swing motion by acquiring correct swing postures, and can train turning motion of his/her shoulder and rotation motion of his/her waist.

The invention relates to a content-based image retrieval apparatus and method via relevance feedback by using fuzzy integral and a computer readable record medium storing programs for realizing the apparatus and method. According to the invention, it is provided a content-based image retrieval apparatus and method in which image features are associated by using fuzzy integral and parameters necessary for the fuzzy integral are adjusted in similarity calculations via relevance feedback so as to improve search results. The method comprises the steps of: measuring similarities according to feature between images stored in a database and a new query image; associating the similarities measured according to feature by using the fuzzy integral to measure similarities according to the fuzzy integral; bringing images sequentially in the order of higher similarity according to the finally obtained similarities and transmitting a search result; and recalculating similarities according to feature via relevance feedback about the query result to output converted images.

Disclosed is an automatic video summarization device and method using a fuzzy OC-SVM (one-class support vector machine) algorithm. A user's subjective decision is reflected in order to generate an effective video summary, and a method for generating flexible video summary information which satisfies the user's environment or requirements is provided. Important video segments are extracted from a given video, and a sequence of key frames is extracted from the video segments, and hence, the user can catch the contents of the video quickly and access desired video scenes.
