박철홍 ( Cheol Hong Park ) 대한주산의학회 2006 Perinatology Vol.17 No.1
목적 : 분만전후 심장근육병증의 초기 임상양상의 특징과 위험요소들을 평가하는 데에 있다. 방법 : 1995년부터 2005년까지 10년간 임신중 혹은 분만 후 심장초음파검사로 심장질환이 있는 것으로 판명된 28명의 산모의 의무기록을 전향적으로 검토하였다. 결과 : 임신중 혹은 분만 후 심장질환이 있다고 한 28명의 환자 중 분만전후 심장근육병증의 진단기준에 부합된 환자는 15명이었다. 이들의 평균연령은 32.5±6.5세였고, 함께 갖고 있던 질환 혹은 상황은 전자간증 40%, 쌍태임신 33.3%, 조기진통 20%, 심근염 6.7%였다. 이들 중 분만 후 자궁근무력증을 보였던 2예(13.3%)를 포함한 5예(33.3%)에서는 중환자실 집중관리를 받았으나 사망한 예는 없었으며 향후 모두 호전되었다. 결론 : 심장근육병증은 서양의 경우에는 임신과 연관된 사망의 원인중 증가하는 원인중의 하나로 꼽히는 반면 본 저자들은 10년간 단 한 예에서도 분만전후 심장근육병증으로 사망한 예가 없었고 모두 예후가 양호하였던 것을 경험하였으며, 향후 이와 관련한 원인적 위험요소들과 인종간의 상이성에 대한 연구가 더 필요할 것이다. Objective : To review and characterize the initial presentation and risk factors of peripartum cardiomyopahty. Methods : We reviewed the medical records of 28 women with a history of heart disease confirmed by echocardiography during pregnancy or the postpartum period between 1995 and 2004. Results : Of a total of 28 women with a history of heart disease during pregnancy or the postpartum period, 15 women met traditional criteria of peripartum cardiomyopathy. Mean age of 32.5±6.5 years and common associated conditions were preeclampsia (40%), twin pregnancy (33.3%), preterm labor (20%), and myocarditis (6.7%). 5 of them (33.3%) including postpartum uterine atony (13.3%) had had ICU care but no deaths occurred (0% mortality) and all of them (100%) had regression of cardiomyopathy. Conclusion : Cardiomyopathy acoounts for an increasing proportion of reported pregnancy-related deaths in western countries, but we experienced no mortality from peripartum cardiomyopathy during a 10-year period. Further studies are required to identify risk factors and racial disparity.

박철홍(Cheol-Hong Park) 산업기술교육훈련학회 2012 산업기술연구논문지 (JITR) Vol.17 No.3
Cam shaft which is a part of automotive engine is very essential to fuel injection timing. The study investigates fracture characteristics of the cam shaft which is made of surface hardening heat treated SM53C. The residual stress and Micro Vickers hardness were tested. The residual stress was run on Advanced Indentation system 3000 and the Micro Vickers hardness tested on MVK-G1. The test results shows that was the greatest compressive residual stress for 1mm and 2mm hardened depth were noticed in depth of 0.8mm and 1.0mm, respectively. The hardness of the cam shaft was improved from 260Hv to 750Hv after surface hardening heat treatment
