심병주,이종민,이승재,김성식,이동현,신우승,유지한,길상현 대한심장학회 2010 Korean Circulation Journal Vol.40 No.10

Percutaneous coronary intervention with stenting is widely used for ischemic heart disease. Because stent loss, which occurs rarely during the procedure, might have dire consequences, such as bleeding, stent embolism, acute myocardial infarction, emergency coronary artery bypass graft, and death, appropriate treatment is needed as soon as stent loss occurs. We report three cases of stent loss which were successfully treated with three different non-surgical methods.

Background and Objectives: As shown in previous studies, pentraxin 3 (PTX3) can be a useful inflammatory marker for metabolic syndrome and central obesity. Serum PTX3 levels are also an independent factor associated with visceral fat area. The aim of this study was to assess the role of PTX3 as an inflammatory maker in patients with central obesity undergoing primary percutaneous coronary intervention (PCI) following an ST-segment elevation myocardial infarction (STEMI). Subjects and Methods: From December 2007 to June 2008, 40 subjects (mean age: 61±11 years, M : F=34 : 6) with STEMI who underwent primary PCI were enrolled. We determined waist circumference, waist/hip ratio, body mass index (BMI), and visceral and total fat area via fat computed tomography (FAT-CT), and compared them with serum PTX3 concentrations. Results: The serum PTX3 concentration was closely related to FAT-CT-estimated visceral fat area (r=0.41, p<0.01) and total fat area (r=0.38, p=0.01), respectively. The serum PTX3 concentration was not related to waist circumference (r=0.27, p=0.20), waist circumference/hip ratio (r=0.25, p=0.16), BMI (r=0.04, p=0.80) and lipid profiles, respectively. Among the parameters determining metabolic syndrome, an increasing visceral fat area had the strongest association with PTX3 concentrations. Conclusion: In patients with STEMI, PTX3 is associated with central obesity and it is significantly and independently correlated with visceral fat area. FAT-CT-estimated visceral fat area is the most reliable factor associated with serum PTX3 levels in patients with STEMI and central obesity.

영재지도교사, 영재학생 및 학부모의 과학 및 과학자에 대한 인식

심병주,윤희숙 韓國英才學會 2013 영재교육연구 Vol.23 No.5

The purpose of this study is to analyze the perception on science and scientists of the teachers who are engaged in the special education for the scientifically gifted, science-gifted students and their parents. For this study, 34 teachers, 222 students and 107 parents answered the questionnaire of the perception on science and Draw-AScience-Test (DAST). The result showed that the three groups generally had a sound recognition but the score of recognition about a 'nature of science' was lower than other domains. The science-gifted students had less cognition about 'science and society' than their teachers and parents, but they had more positive perception about 'science learning' than their parents significantly. All of the three groups had the stereotyped image of scientist. About the internal images of scientists, three groups had a similar perception, and they showed higher scores in the cognitive aspect than emotional or ethical aspects. And the science-gifted students showed the significantly higher scores than their teachers and parents in diligence, imaginative power, concern about other people, respect for other's opinion, humor, artistic sense, respect for human, desire for peace. Three groups turned out to be influenced by movie, science journal, and biography as a source of scientist's image, but their contribution was different among groups. 본 연구의 목적은 영재교육을 담당하고 있는 교사와 영재교육을 받고 있는 학생 및 그 학부모의 과학에 대한 인식과 과학자에 대한 외적, 내적 이미지 등을 비교 분석하는 것이다. 이를 위해 서울특별시 소재 교육지원청 초등과학영재교육원 및 영재학급의 영재지도교사 34명, 영재학생 222명, 학부모 107명을 대상으로 과학에 대한 인식 검사와 과학자 이미지 검사(Draw-A-Science-Test)를 실시하였다. 이들의 과학에 대한 인식을 분석한 결과, 세 집단 모두 전반적으로 올바른 인식을 갖고 있었으나, 과학의 본성에 대한 인식점수는 상대적으로 낮았다. 학생들은 학부모나 교사에 비해 과학과 사회에 대한 인식이 부족하였으며, 과학공부에 대한 인식은 학부모에 비해 유의미하게 긍정적인 인식을 갖고 있었다. 과학자에 대한 외적 이미지에 있어서 세 집단 모두 정형화된 인식을 갖고 있었으며, 과학자의 내적 이미지에 있어서는 정서적 윤리적 측면보다 인지적 측면에 높은 점수를 나타내었다. 이 중 근면성, 상상력, 타인 염려, 의견 존중, 재미, 예술 감각, 인간 존중, 평화 등의 영역에서 학생들의 인식이 교사나 학부모의 인식에 비해 유의미하게 높은 점수를 나타내었다. 과학자에 대한 이미지 출처로 영화, 과학 잡지, 위인전 등에서 세 집단 모두 높은 빈도를 나타냈으나, 각 집단별 응답 비율이나 경향성에는 다소 차이를 보였다.

물질의 입자적 관점 도입에 대한 초등과학 교육과정 및 교과서 국제 비교

심병주,윤희숙,Sim, Byeongju,Yoon, Heesook 한국초등과학교육학회 2018 초등과학교육 Vol.37 No.2

The purpose of this study is to compare the elementary science curriculum and textbooks of Korea, the United States, Japan, and Singapore to know how the contents on particulate concept of matter is introduced and expressed. In Korea, particulate concept of matter was adopted as a term for 'molecules' in the 3rd through 6th curriculum, and the term for 'particles' was adopted in the 2009 revised curriculum. In the United States, NGSS adopted the term 'particle' in fifth grade. Japan presented the concept of 'particle' as a core concept of matter in the commentary, and the expressions 'particles' were being introduced in the textbooks. But it did not cover particulate nature of matter at the elementary school level in Singapore. An analysis of elementary textbooks in Korea, the United States and Japan except Singapore showed particulate expressions in 'dissolution', 'state change of water', 'gas pressure and volume', 'combustion and extinguishment' units. Korean textbook was only being introduced in 'dissolution' and 'gas pressure and volume', but in the textbooks of Japan and the United States, water was expressed as particles in 'state change of water' unit. Discussion and implication on the introduction of particulate concept to elementary science curriculum and textbooks were suggested based on the results.

동제련 슬래그 잔골재를 혼입한 포러스 콘크리트의 물성에 관한 실험적 연구

김영수,심병주,이동운 대한건축학회지회연합회 2011 대한건축학회연합논문집 Vol.13 No.4

본 연구는 동제련 슬래그를 혼입한 포러스 콘크리트의 기본 특성을 알아보고자 한다. 공시체는 포러스 콘크리트의 여러 배합비(10, 20, 30, 50%)로 동제련 슬래그를 혼입하여 만들었다. 다른 공시체는 보통 포러스 콘크리트에 강사, 부순골재를 포함하여 포러스 콘크리트로 만들었다. 모든 공시체의 W/B와 공극률은 0.25와 20%로 사용하였다. 실험은 압축강도, 휨강도, 연속공극률, 투수 계수를 측정하였다. 실험 결과는 다음과 같다. 포러스 콘크리트에서 동제련 슬래그의 혼합률이 0%에서 50%로 증가할 때, 포러스 콘크리트의 압축강도는 14%에서 34%로 증가하였다. 그리고 포러스 콘크리트에서 동제련 슬래그의 혼합률이 0%에서 50%로 증가할 때, 포러스 콘크리트의 휨강도는 25%에서 40%로 증가한 것을 알 수 있었다. 전체 공극률과 연속 공극률을 관찰하였을 때, 잔골재의 혼합률이 증가할 수 록 공극률이 감소하는 것을 알 수 있었다. 투수 계수 시험 결과, 전 시편의 경우 Japan Concrete Institute-Eco Concrete Committee의 기준인 0.1㎝/sec을 상회하였으나 동제련 슬래그 공시체의 경우 혼입율이 20% 이상이면 전체 공극률과 연속 공극률을 감안하여 사용하여야 한다. This study intends to identify basic properties of porous concrete mixed with cooper slag. The specimens were made of cooper slag with various mixing ratio(10, 20, 30, 50%)porous concrete. Other specimens were made with ordinary porous concrete and porous concrete containing river fine aggregate and crush fine aggregate. All specimens of W/B and target void ratio were fixed 0.25 and 20%. The experiment were measured by compressive strength, flexural strength, total , continuous void ratio, and coefficient of permeability. The results of the experiment are as follow. When mixing ratio of cooper slag in porous concrete was increased from 0% to 50%, it was observed that compressive strength of porous concrete was increased from 14% to 34%. And mixing ratio of cooper slag in porous concrete was increased from 0% to 50%, it was observed that flexural strength of porous concrete was increased from 25% to 40%. Observing of total void ratio and continuous void ratio, all specimens showed that as mixing rates of fine aggregate were increased as the porosity were decreased. The results of coefficient of permeability was met up to 50% of mixing ratio specimens which is the standard of Japan Concrete Institute-Eco Concrete Committee(0.1cm/sec) but if more than 20% of specimens think about total void ratio and continuous void ratio.

이현욱,윤호중,심병주,이승재,박미연,정진욱,구관민,전희경,이지은,권병진 한국심초음파학회 2012 Journal of Cardiovascular Imaging (J Cardiovasc Im Vol.20 No.4

Cardiac calcification usually occurs in patients with end-stage renal disease. However, rapid progression of cardiac calcification is rarely associated with secondary hyperparathyroidism of end-stage renal disease. We report a patient with end-stage renal disease who showed moderate left ventricular hypertrophy at the first echocardiography, and showed severe myocardial calcification and severe mitral valve stenosis 4 years later. We suspected a rapid progression ‘porcelain heart’ cardiomyopathy secondary to hyperparathyroidism of end-stage renal disease. The patient underwent parathyroidectomy, and considered mitral valve replacement.

A 38-year-old man visited our emergency department presenting with a 6-day persistent fever. The man had undergone an orthodontic procedure 7 days prior to the visit. He had a fever with a temperature of 38.2°C and a diastolic murmur (grade III)was detected at the left sternal border. Reddish-brown lines beneath the nails were present, and raised lesions which were red and painful were detected on the soles of the patient’s feet. Laboratory findings showed an elevated inflammatory marker. Transthoracic and transesophageal echocardiograms, showed a bicuspid aortic valve, and moderate aortic regurgitation and vegetation were noted. Treatment with antibiotics was given, but 4 days later, a 12 lead electrocardiogram revealed complete atrioventricular (AV) block. Immediately, a temporary pacemaker was inserted, and the following day an aortic valve replacement was performed. Intraoperative findings revealed a fistula around the AV node. He has suffered no subsequent cardiac events during the follow-up.
