N/A Korean hemorrhagic fever which was recognized for the first time in Korea near the Demilitarized Zone between North and South Korea in 1951 during Korea War have spread to the southern part of the Korean peninsula and several hundreds of cases are clinically and serologically diagnosed each year. However the Northern Part of Kyoung Ki Do is still remained as epidemic area. In recent years, we experienced 55 cases of Korean Hemorrhagic Fever in the northern part of Kyoung Ki Do during the period, 1984-1986, and we found different clinical patterns of Korean hemorrhagic fever from those reported earlier. Here we report the epidemiological and clinical observations with laboratory findings. 1) The disease was prevalent in adult male farmers and the epidemic seasons were fall and early winter. The epidemic areas of the disease are mainly Yang Ju, Yeoncheon and Pocheon. 2) Clinical pictures of Korean Hemorrhagic Fever were characterized by headache (76%), abdominal pain (69%), nausea & vomiting (67%), fever (56%) and myalgia & general aching (49%). 3) On physical examination, fever (56%), abdominal tenderness (36%), tachycardia (35%), hypotension (27%), petechia (24%), conjunctival injection (22%) and facial flushing and edema (16%) were found. 4) On laboratory examination, leukocytosis, thrombocytopenia, left shift of leukocyte, toxic granule, proteinuria, microscopic hematuria and increased specific gravity were found. Blood chemistry findings were characterized by increased BUN & creatinine, increased SGOT & SGPT, hyponatremia, increased LDH & FDP and hyperkalemia. 5) Clinical forms of typical hemorrhagic fever were as follows: Typical oliguric type 49%, typical nonoliguric type 21% and atypical type 29%. 6) Double infection to Leptospirosia was found in 8 cases.

On this paper, first, we make the NC-code of Insert die-casting as the object model using PowerMill. And then, analyze cutting force by Toolpath in Insert mold machining using Production Module of AdvantEdge which is cutting force analysis program. After that, we come up with the optimum conditions of productivity improvement throughout the analysis result of before and after optimization of cutting force, machining time variation, and surface roughness by changing min tangential force to 80, 85, 90% of max tangential force.

Recently, Cycle of the product is shortened Because of diversification of consumer needs and demands for high performance & lightweight & precision of a machine part is on the increase. Therefore, In addition to increasing mould products including 3D surfaces, The interest in ball-endmill often using finish cutting has been focused. So in this study, we consider that peak point of ball-endmill is not included on cutting at inclined plane and analysis cutting force in tool at inclined plane and check temperature on cutting.
