우리 기업의 글로벌 경쟁력 강화를 위한 임금체계 개편이 시급
정조원 한국경제연구원 2017 KERI 칼럼 Vol.2017 No.12
우리나라와 EU 총 25개국의 근속 20~29년과 1년미만 근로자의 임금격차를 비교한 결과(2014년 기준) 한국 4.04배, 키프로스 2.44배, 포르투갈 2.09배, 스페인 1.80배 등의 순이었다. 한국의 경우 관리자 직종을 제외하거나, 정규직만을 대상으로 분석한 경우에도 근속 20~29년-1년미만 근로자간 임금격차가 각각 3.97배, 3.29배로 높게 나타났다. EU 국가들은 직무급이 정착되어 근속년수에 따른 임금격차가 높지 않은 반면, 한국은 연공서열형 임금체계인 호봉급이 많아 임금격차가 많이 나는 주요 원인이 되고 있다.
Echocardiographic Evaluation of Atrial Septal Defect Device Closure
정조원 한국심초음파학회 2007 Journal of Cardiovascular Imaging (J Cardiovasc Im Vol.15 No.1
With further development of transcatheter techniques and improved occlusion devices, percutaneous closure has become the treatment of choice for secundum ASD. The Amplatzer septal occluder device is frequently used for ASD occlusion due to its straightforward implant technique and efficacy in occluding a wide range of ASD sizes. TEE is vital in the recognition of morphologic variations of the ASD and patient selection. It allows clear visualization of the defect and the device during the procedure, precise measurements of stretch diameters, guiding of deployment, and stable positioning of the device. This is especially important in patients with large ASDs or multiple ASDs and those with atrial septal aneurysm. With TEE, incorrect positioning of the device can be detected while it is still screwed to the delivery cable, which allows its early redeployment, before any complications occur. Compared with the patients undertaken surgical repair, the left ventricular function using strain rate imaging was preserved after the device closure. Echocardiographic evaluation for ASD device closure is essential in patient selection, during procedure, after occlusion, and long term follow-up.

Atrial septal defect is common congenital heart disease in children. Inheritance follows the multifactorial mode primarily but in certain families autosomal dominant transmission is evident. In Korea, there has been no case report of twins with ASD or any other congenital heart diseases in children, while there have been several reports of sildings and twins with ASD or other congenital heart diseases in other countries. Herewith we report a monozygotic pair of twins with atrial septal defects who were diagnosed by cardioc catheterizarion and confirmed by operation, with brief reriew of the literature.

Right-sided heart failure is a major problem among patients with congenital heart diseases, due to the prevalence of congenital heart defects and the association of pulmonary hypertension. More attention is focused on the structure of the right heart particularly in association with congenital heart defects and chronic lung disease. The right ventricle (RV) may support the pulmonary circulation, and sometimes the systemic circulation (systemic RV) in congenital heart defects. Despite major progress being made, assessing the RV remains challenging, often requiring a multi-imaging approach and expertise (echocardiography, magnetic resonance imaging, nuclear and cineangiography). Evidence is accumulating that RV dysfunction develops in many of these patients and leads to considerable morbidity and mortality. While there is extensive literature on the pathophysiology and treatment of left heart failure, the data for right-sided heart failure is scarce. Therefore RV function in certain groups of congenital heart disease patients needs close surveillance and timely and appropriate intervention to optimise outcomes. An understanding of RV physiology and hemodynamics will lead to a better understanding of current and future treatment strategies for right heart failure. This will review right- sided heart failure with the implications of volume and pressure loading of the RV in congenital heart diseases.
