본 연구에서는 볼엔드밀과 플랫앤드밀에 의해서 야기되는 절삭력을 가상적으로 평가할 수 있는 기반을 구축하기 위한 노력으로써 가상가공기법을 이용한 절삭력 해석 시스템을 구현하였다. 공구의 기하학적 제원과 공작기계(밀링머신, 머시닝센터)의 운전 조건에 의해서 변화되는 절삭력은 공작물과 공구의 접촉영역 내에 위치한 미소 절삭날에 적용하는 미소 절삭력들을 중첩시키는 방법을 통해서 해석하였다. 특히 구조변형을 고려한 절삭력은 절삭력과 구조변형의 평형조건을 이용해서 결정하였다. 아울러서 볼엔드밀과 플랫엔드밀의 절삭력에 대한 실험결과와 해석결과의 비교를 통해서 본 연구에서 개발한 절삭력 해석 시스템의 유용성을 입증하였다. In this study, a cutting force analysis system for ball and flat end-mills is realized based on the virtual manufacturing technologies. Cutting force which depends on the specification of cutting tool and operating conditions of machine tool(milling machine, machining center), is predicted by superposing the infinitesimal cutting forces on infinitesimal cutting edges existing in the contact area between cutting tool and workpiece. Especially, the equilibrium condition between cutting force and structural deformation of cutting mechanism is introduced to determine the cutting force considering the influence of structural deformation. And comparison between the predicted and measured cutting forces for ball and flat end-mills shows the effectiveness of the cutting force analysis system developed in this study.

The purpose of this study was to investigate the association among nutrient intakes and health-related lifestyles with cardiovascular disease risk assessed by blood lipid profile according to Apolipoprotein E genotypes. Middle-aged industrial male workers who had completed their annual medical examination were recruited and data of 675 subjects who finished the nutrient survey were used in the analysis. Anthropometric parameters, dietary assessment (FFQ), health-related lifestyles and blood profiles were used for statistical analyses. Apo E genotype groups were classified into the following three genotypes: Apo E2 group (including E2/E2, E2/E3, E2/E4), Apo E3 group (including E3/E3), Apo E4 group (including E3/E4, E4/E4). The frequency of Apo E2, E3, and E4 allele were 13.3%, 75.0% and 11.7% respectively. There were no significant differences in the anthropometric parameters depending on different Apo E genotypes. Also, no significant differences in the nutrient intakes were found according to the genotype groups. The nutrient intakes of all subjects were similar to or higher than the level of KDRIs (Dietary Reference Intakes For Koreans) except for intakes of calcium (67.44% of KDRIs), vitamin A (73.83% of KDRIs) and vitamin B2 (78.02% of KDRIs). Also, there were no significant differences of health-related lifestyles according to Apo E genotype groups. As for the lipid profiles, Apo E4 group had significantly higher total and LDL-cholesterol concentrations than the Apo E2 group (p < 0.05). We confirmed that plasma total and LDL-cholesterol concentrations were greatly influenced by Apo E genotypes. However, nutrient intakes and health-related lifestyles were not associated with Apo E genotypes.

In this study, we analyzed the characteristics of atmospheric stability to investigate local environment change at an atomic power plant in Gori region. The used data was obtained from field observation of major meteorological variables such as wind direction and speed, air temperature, relative humidity, and solar radiation using AWS (Automatic Weather System) in Gori region from February to September in 2003. As a result, when strong northerly winds (more than 4~6 m/s) and weak northwesterly winds (2~3m/s) blow, atmospheric stability was neutral and stable from winter to spring, respectively. Atmospheric stability (neutral) in summer was similar to that in two other seasons (winter and spring), but it was stable for weak southwesterly winds (2~3 m/s). Finally, atmospheric stability was neutral for strong winds (over 4~6 m/s) in fall without respect to wind direction, while that was stable for very weak winds (less than 2 m/s).

Hepatocellular carcinoma(HCC)is one of common causes of cancer-related death in Korea where the majority of HCC patients were Hepaitc B virus(HBV)carriers and have cirrhosis. Transarterial chemoembolization(TACE)is commonly applied to the treatment of multinodular HCC in Korea and careful selection of candidate is important for the risk of various side effects. Besides common side effects as fever, nausea, abdominal pain and elevation of liver enzyme, TACE may predispose to hepatic failure, ischemic cholecystitis, pulmonary embolism, cerebral embolism and pneumonitis. In previous studies, some cases of pulmonary and cerebral embolism cases were reported but lipiodol pneumonitis after TACE was rarely reported. A 65-year-old woman with a multinodular HCC associated with HBV infection, was treated with TACE. Seven days after the procedure, nonspecific respiratory symptoms such as dyspnea and dry cough developed. Chest X-ray and chest computed tomography showed diffuse ground glass opacities in whole lung fields, suggestive of lipiodol pneumonitis. After several days of supportive care with steroid administration, radiologic abnormalities and subjective symptoms were much improved, considered that the disease was compatible with lipiodol pneumonitis.
