The purpose of this study is to predict the roundness of Numerical Control Machining so that helps the operator to choose the right machining conditions to produce a product within the given error limits. Learning of neural network is Backpropagation theory. From this study, the base was set to setup the database to produce precisely machined product by predicting the rate of error in the fabrication facility which does not have the environment to analyze it.

Regional lymphadenitis is the most common complication following BCG vaccination in this country. The literature describes controversial results with medical, surgical and combined therpy. The purpose of this study is to clarify the therapeutic effect of isoniazid(INH) after surgical procedures. The early and late postoperative complications of 136 children with lymphadenitis following BCG vaccination at the Taegu Fatima Hospital between March 1985 and February 1996 were reviewed. In 90 children, INH was given for 3-4 days before operation and for 3 months after surgery. In the other 46 cases, INH was not given during the pre- or postoperative period. Surgical procedures were excision or incision and currettage according to the states of lesions. Postoperative complications were fluid accumulation, wound infection, sinus formation and others. Complication rates were 14.4 % in INH-treated group and 13.0% of INH-nontreated group. The difference was not significant. There was no recurrence or other late complication in either groups. The result suggest that surgical excision or incision and currettage are sufficient for the treatment of regional lymphadenitis following BCG vaccination and postoperative INH therapy is not necessary.

Due to the increasing demand for carious methodologies to improve the quality of products were introduced. A Brush the most frequently used type of grinding process is one of the deburring. in order to produce consistent burr shape, various machining conditions have been combined and applied to disk grinding process. Between the workpiece and the grinding disc to earn depends on the angle of the slope has been observed. Drastic increase of tool wear has been also observed along the inclination angle variation. Various burr shapes have been captured and analyzed using image processing technique.

Recently, trouble of sand supply is occurred according to exhaustion of natural sand resources. To solve this problem, sea sand and crushed sand are used. But, necessity of water reducing agent because quality of concrete that use sea sand and crushed sand is deteriorated. Therefore in this study was examined on the engineering properties of concrete with kind of fine aggregate and addition ratio of water reducing agents. As a result, if addition ratio of water reducing agents increase, bleeding capacity was increased and setting time delayed regardless of kind of aggregate. Moreover compressive strength appeared similar standard in early-age as time goes by.
