본 논문의 목적은 2000년대 이후 미국의 초등학교에서 보편화되고 있는 생활통지표 작성의 새로운 경향을 살펴보고, 우리나라의 초등학교 생활통지표의 개선을 위한 시사점을 탐색하는 것이다. 이러한 목적을 달성하기 위해 미국 초등학교의 생활통지표를 분석하였고, 그 결과 2000년대 이후 미국에서는 기준 중심 생활통지표의 확대 및 생활통지표의 On-line화가 이루어지고 있음을 발견하였다. 이러한 경 향이 우리나라의 초등학교 생활통지표에 시사하는 점은 다음과 같다. 첫째, 생활통지표 본연의 기능 회 복 및 강화를 위한 노력이 필요하다. 둘째, 동일한 맥락 에서, 생활통지표의 On-line화 등을 통해 최종 결과만이 아닌 과정에 대한 정보를 제공하는 방안을 모색할 필요가 있다. 셋째, 기준 중심 등급 기재 및 생활통지표의 도입을 고려해볼 필요가 있다. The purpose of the st udy is to examine t he current trend of the eleme ntary school’s repo rt ca rds in th e U.S. and to sugg est some measures to improve t hose of Korean elementary schools. For the p urpose of the study, the resear cher examined the eleme ntary sch ool’s report cards and finds two trends: expansio n of standard-based report c ards and On-line services. These findings suggest t hat Korean elementa ry schools should make an effor t to recover the schoo l report c ard’s original role s which are providing information s to and communicating with parents and motivating students. Second, Korean elementary schools try to pr ovide informations not only on the result but also the proces s of students’ acti vities to parents by On-line st udent report cards. Finally, to provi de more c orrect informatio ns on their children and to h elp parents to unders tand info rmations at the rep ort card, Korean elementary sc hools need to ado pt the standard-ba sed report card syst em.

연구배경: 심방세동은 심방의 확장과 심실 기능이 저하된 경우에 자주 동반되는 비교적 흔한 부정맥이다. 하지만 심방세동의 병인에 대해서는 아직 명확하지 않다. 본 연구는 발작성 심방세동을 갖는 환자에서 도 플러 심근능력 지표 (Tei index)을 이용하여 심실 기능을 평가하고자 하였다. 방법: 발작성 심방세동을 갖는 환자 25명(남 14, 여 11, 61±3세)과 대조군 25명 (남 11, 여 14, 58±10세)을 대상으로 하였으며, 75세 이상의 고령 환자, 고혈압, 당뇨, 관상 동맥질환, 판막질환을 갖는 환자는 제외하였다. Tei index는 isovolumetric contraction time (ICT)과 isovolumetric relaxation time (IRT)를 ejection time (ET) 으로 나눈값으로 정의하였다. 결과: 양 군 간에 임상적인 양상은 큰 차이가 없었고. 심 초음파상 심실 중격 두께(8.9±1.8 vs 11.6±3.2 mm, p<0.05), 좌심실 질량지수 (85.6±45 vs 107±33 g/m2, p<0.05), 는 발작성 심방 세동군에서 의의 있게 높았다. 좌심실의 확장기말 길이 (49±4 vs 51±4 mm), 수축가말 길이 (29.7±3 vs 33.1±5 mm), 좌심실 구혈률(69±6 vs 65±8%)은 유의한 차이가 없었다. 좌심방의 전후 길이 (32.8±4.3 vs 39.5±8.2 mm, p<0.05),은 발작성 심방세동 군에서 의의 있게 높았으며 좌심방면적 분획변화율(fractional area change)은 (39.5±8.2 vs 32.8±4.3%, p<0.05),은 의의 있게 낮았다. 발작성 심방세동 군에서 IRT (59±23 vs 76.5±21 msec, p<0.05),는 길었으며, ET (332.9±23 vs 303±27 msec, p<0.05),는 짧았다. ICT (43±21 vs 53±17 msec)는 통계학적으로 차이가 없었다. Tei index (0.33±0.01 vs 0.4±0.12, p<0.05)는 발작성 심방세동 군에서 의의 있게 높았다. 결론: 본 연구에서 발작성 심방세동의 병인에 있어서 좌심방의 기능 저하뿐만 아니라, 좌심실의 이완기 장애 도한 중요한 역할을 하고 있음을 알 수 있었다. Background and Objective : Atrial fibrillation is comparative common arrhythmia, when left atrium is enlarged and the ventricular function of the heart is fallen. However, cause of a Atrial fibrillation is not confirmed. This research wished to evaluate the function of the ventricle using Doppler myocardial performance index (Tei index) in patient who have paroxysmal atrial fibrillation. Subjective and Method : This study was done with 25 people (man 14, woman 11, age: 61 ±8 yr) who had paroxysmal atrial fibrillation and 25 people (man 11, woman 14, age: 58 ±10) who had no abnormality(control group). Among the researched patient, who have advanced age more than 75 years old, high blood pressure, diabetes, coronary arteries disease, valvular heart disease were excluded. Myocardial performance index(Tei index) defined by value that divide isovolumetric contraction time(ICT) and isovolumetric relaxation time(IRT) by ejection time (ET). Results : In aspect about clinical characteristics, the LV septal wall thickness(8.9 ±1.8vs 11.6 ±3.2 mm, p<0.05) and LV mass index (86±45 vs 107±33 g/m2, <0.05) were significantly higher in paroxysmal atrial fibrillation group than control group. The differences in LV end diastolic diameter (49±4 vs 51±4 mm), end-systolic diameter (29±7 vs 33±1 mm), left ventricle ejection (69±4 vs 65±5 %) between two groups were not statistically different. In paroxysmal atrial fibrillation group, LAAP diameter (33.1±4 vs 39.6±8.2 mm, p<0.05) was significantly long, left atrial fractional shortening (41±6 vs 36±6 %, p<0.05) was significantly low. In paroxysmal atrial fibrillation group, the isovolumetric relaxation time(IRT) was significantly long (59±22 vs 76±21 msec, p<0.05) and ejection time(ET) was significantly short (333±23 vs 303±28 msec, p<0.05). Isovolumetric contraction time(ICT) was not statistically different (43±21 vs 53±17 msec). Doppler Myocardial performance index(Tei index) was significantly high in paroxysmal atrial fibrillation group(0.30±0.1 vs 0.42±0.12, p<0.05). Conclusion : As result of this research, we can know that there is diastolic dysfunction of left ventricle as well as depression of left atrial function at paroxysmal atrial fibrillation and diastolic dysfunction of left ventricle can be a cause of paroxysmal atrial fibrillation.

조기강도 개선제를 활용한 고성능 수축저감제의 성능 개선

박종필(Park, Jong-Pil),정용욱(Jung, Yong-Wook) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.4

콘크리트의 내구성 저하로 인한 균열의 보수 및 보강에 소요되는 비용은 콘크리트 구조물의 유지비용 증대로 연결되 어 균열발생 저감에 대한 연구가 요구되고 있다. 특히, 전력공급용 시설인 전력구의 경우 지하 매설물이므로 보수 및 보강은 경제적으로 큰 부담이 된다. 그러므로 지하매설 전력구의 경우 효과적인 균열 저감 방안이 설계 초기단계부터 요구되어진다. 본 연구는 전력구용 저수축 콘크리트 제조를 위한 수축저감제 개발의 일환으로 수축저감제 사용 콘크리트의 초기 강도 개선 을 위해 TEA를 검토하였다. 검토결과, TEA를 수축저감제의 3% 사용할 경우 조기 강도가 크게 개선되었으며, 수축저감 효과 도 우수한 것으로 확인되었다. 또한, TEA 3 %에 수축저감제 2.0 % 혼합하여 적용하였을 경우 압축강도 특성 및 건조수축 길이변화 실험결과에서 가장 우수한 것으로 나타나 수축저감제로서의 가능성을 확인하였다. 추후 수축저감제의 범용적인 적용성 검토를 위하여 수축저감제의 사용재료 변화 등에 대한 다양한 재료변수 요인 검토를 통하여 수축저감제의 성능 검토 가 필요할 것으로 사료된다. Studies aimed at reducing the occurrence of cracks by the shrinkage of concrete are in demand because the repair and reinforcement for cracks caused by declining concrete durability costs the user to maintain the concrete structure. In particular, in underground power facilities for power transmission, the cost is a heavy burden to repair and reinforce. For this reason, underground power facilities demanded effective methods for crack reduction at the engineering design step. This study, as a part of the development of shrinkage reducing agent for low shrinkage concrete on underground power facilities, investigated TEA to complement the shrinkage reducing agent to improve the early strength of concrete. In the case of TEA 3% as a shrinkage reducing agent, the early strength was improved significantly, and the shrinkage reducing effect was excellent. In addition, TEA 3.0 % and the shrinkage reducing agent 2.0 % showed excellent shrinkage property and compressive strength. On the other hand, more study of shrinkage reducing materials, including performance reviews on the shrinkage reducing materials with variable factors and type of materials, will be needed to generalize these results.

초등학교 체육교과 전담교사제의 실태 분석

박종필(Jong Pil Park) 한국체육교육학회 2000 한국체육교육학회지 Vol.4 No.2

The major goal of this research is to analyze the effectiveness of the current Exclusive Physical Educator System(EPES) in elementary schools and to consider alternatives which improve the problems found in the course of actual enforcement. Results on perception for this system are analyzed from questionnaire survey made by 124 Homeroom Teachers(HT) and 132 Exclusive Physical Education Teachers(EPET) having secondary teacher`s certificate in elementary schools in Pusan. By all results of this research, most of HTs understand for EPETs` necessity in the respects that EPES can provide students for various physical experiences and reasonable management of Physical classes, and Physical subject is professional functional subject. While the EPETs have more positive understanding for current management of EYES, a great number of HTs have negative understanding for this. The reasons of negative answers by HTs are shortage of short-term teachers, HT`s avoidance for EPET, and shortage of total teachers, and the reasons by EPETs are poor physical environments, avoidance of HTs, and shortage of short-term teachers. Most of EPETs have charge of about 20 hours a week in 5th and 6th grades. A great number of EPETs have deep knowledge for the curriculum and have achieved learning goals efficiently compared with HTs. Also it is said that HTs have difficulty in textbook study and practical ability, and EPETs have difficulty in shortage of teaching materials and equipments for achievement of learning goals. It shows that HTs prefer to current system, whereas EPETs want to get elementary teacher`s certificate based on the EYES for their reasonable future course. Also EPETs answered that class responsible hour should be adjusted into 15 to 20 hours, and one teacher per four classes should be arranged in over 4th grade class. It is perceived reasonably that EPETs should be educated at Physical Education Department in National University of Education, and should be made up of current short-term teachers. Regarding with factors of efficiency reinforcement in EYES, HTs answered that allowance should be given to EPETs, and systematic matters such as education for special Physical teachers should be strengthened. In the other hands, EPETs pointed out more realistic problems for current Physical classes like teaching materials and security of facilities such as gymnasium.

This study has tried to produce low-carbon inorganic composites which can be produced at a normal temperature, with no processing of high temperature plasticity, using only alkali accelerator by complementing the weak points of blast furnace slag, red-mud, and silica fume to be used as cement substitute, (not the normal concrete admixture). In order to compensate the contraction crack which it generates after manufacturing, the magnesium oxide (MgO) powder is mixed and it utilizes as basic data of the low carbon inorganic composites. In addition, compressive strength according to the curing condition of the inorganic composites mixing the MgO powder and contraction change properties tried to be examined.
