강혜영,유현실 한국직업능력개발원 2007 직업능력개발연구 Vol.10 No.1

본 연구의 목적은 한국폴리텍대학(구, 기능대학) 학생들이 최근 유용한 학습방법으로 제시되고 있는 자기조절학습 전략을 어느 정도 활용하는지를 살펴보려는 것이다. 이를 위하여 한국폴리텍대 학생을 대상으로 자기조절학습 측정검사(양명희, 2000)를 실시하였으며 총 8개교의 학생 781명의 자료가 분석되었다. 주요 연구결과는 다음과 같다. 첫째, 폴리텍대 학생들은 전체적으로 인지조절(M= 3.02~3.35)이나 동기조절 전략(M= 2.99~3.39)에 비해 행동조절 전략(M= 2.80~3.02)을 상대적으로 덜 사용하는 것으로 나타났다. 특히, 자기조절학습의 하위 전략 중에는 학업시간 관리 전략(M= 2.80)을 가장 덜 사용하며, 숙달목적지향성 전략(M= 3.39)을 가장 많이 사용하는 것으로 나타났다. 둘째, 연령에 따른 자기조절학습 전략 활용의 차이를 살펴본 결과, 인지조절, 동기조절, 행동조절학습전략 모두에서 17-19세 연령 집단이 자기조절학습전략을 가장 덜 사용하는 것으로 나타났다. 셋째, 출신고교에 따른 자기조절학습전략 활용의 차이를 살펴본 결과, 인지조절, 동기조절, 행동조절 학습전략 모두에서 농업고등학교 졸업자 집단이 자기조절학습전략을 가장 덜 사용하는 것으로 나타났다. 이러한 결과를 토대로 볼 때, 폴리텍대 대학생들에게 학업시간 관리 및 행동통제에 대한 교육과 상담 프로그램이 절실히 요청된다고 하겠다. 특별히, 다양한 연령대와 출신고교의 학생들이 재학하고 있는 폴리텍대학의 경우, 17-19세 연령대의 학생들과 농업고등학교 출신 학생들을 대상으로 한 학습관련 교육과 상담 프로그램이 마련될 필요가 있어 보인다. The purpose of this study is to examine the utilization of self-regulated learning strategies which have been suggested as a useful learning method for polytechnic college students, The Self-regulated Learning Inventory(Yang, 2000) was administered to 781 students selected from eight polytechnic colleges. Results were found as following. First, Polytechnic college students used strategies of behavior control (M=2.80~3.02) less than those of cognitive control (M=3.02~3.35) or motivation control (M=2.99~3.39). Specifically, study time control (M=2.80) was used the least, and mastery goal orientation strategy (M=3.39) was used the most. Second, the comparison between different age groups upon self-regulated learning showed that the age group of 17-19 years old used all the self-regulated learning strategies the least. Third, comparisons between students with different high school backgrounds upon self-regulated learning showed that students from agricultural high schools used self-regulated learning strategies the least. Implications were discussed for educational and counseling programs regarding the study time management and behavior control, specifically for students of younger age and those from agricultural high schools.

미국 Medicare 투석환자 치료의 질 지표 개발 : 4가지 주요 치료영역을 바탕으로

강혜영 한국의료QA학회 2000 한국의료질향상학회지 Vol.7 No.2

Background : There has been a concern that the quality of care provided to end-stage renal disease (ESRD) patients in the United States may not be as good as recommended. This paper illustrates a composite measure to assess, the quality of care received by ESRD patients undergoing in-center hemodialysis by incorporating outcomes for 4 major treatment areas. The 4 treatment areas are: dialysis treatments, anemia control, nutritional management, and blood pressure control. Methods : The major data source for the study was the United States Renal Data System (USRDS) Dialysis Morbidity and Mortality Study Wave 1 (DMMS-1) d Sixteen categories of a composite quality in-dicator were constructed by combining 4 dichotomous variables (16=2*2*2*2). representing the optimal vs. less than optimal level of outcome for each of the 4 treatment outcome measure respectively. Optimal outcome level for each treatment area was defined based on the recommendation from the National Kidney Foundation: (a) delivered dialysis doses (Kt/V) ≥ 1.2: (b) hematocrit level ≥ 30%: (c) serum albumin concentration ≥3.8g/di : and (d) blood pressure of <140 / <90mmHg. The 16 quality indicator were ranked according to their relative quality weights, which were estimated from its association with the relative risk of survival, adjusting for patient's baseline severity and dialysis facility characteristics. Results : Out of the entire sample of 2.179 patients, only 229 (10%) meet th recommended outcome levels for all 4 treatment areas. Overall, the study patients were distributed evenly over the 16 quality indicators, indicating a great variation in the quality of 'ESRD care. It appears that the rank of the 16 quality-indicators is driven by serum albumin concentration, suggesting that serum albumin concentration may be the most powerful predictor of ESRD patient survival among the 4 outcome measures. Conclusion : The developed quality indicator has the advantage of describin a range of care for dialysis patients and thus providing a more complete picture of care as compared to previous studies that have focused on only single or few components of the ESRD care.

The purpose of this study is to compare and to evaluate the effects of the degree of saturation on the progression of artificial root caries lesion. A total of 8 human premolars without any defects and cracks selected and the cementum were removed and the teeth were cleaned with ultrasonic device and pumice without fluoride. Each tooth was sectioned into 6 pieces and they were ground with #800 sandpaper until they had a thickness of 200 ㎛. Specimens were applied with nail vanish except for the 2-3 mm window area after application of bonding agent. Under the constant pH, the specimens were divided into 6 groups (degree of saturation: 0.1415, 0.1503, 0.1597, 0.1676, 0.1771. 0.1977). Each group was immersed in acid buffer solution for 1, 2, 3, 5 days under controlled temperature (25℃) and imbibed in water and examined using the polarizing microscope. The results were as follows 1. Although the degree of saturation of demineralization solution decreased, the depth of penetration in the dentin was constant. 2. Erosion was observed on the surface of all the teeth in the group Ⅰ, Ⅱ. In the group Ⅲ, Ⅳ, Ⅴ, surfaces were not changed. The teeth in the group Ⅵ showed the more mineralized surface but not the shape of the dentinal tubules distinctively. 3. In all groups, the lesion progressed rapidly at the first day of the experiment, but increased gradually as time elapsed.

This research used cosmos(Cosmos bipinnatus Cav.) and sunflower(Helianthus annuus L.) to test the possibility of phytoremediation, an environment-friendly heavy metal removing method. I examined the emergence, growth rate and physiological responses and confirmed heavy metal accumulation of Cd and Cu treatment and pH treatment-affected plants at early growing period. The emergence and growth rate was shown the most low in the Cu 2000uM. Chlorophyll and soluble protein content according to pH concentration were a little bad in their treatment plot compared with the control and were a little bad as pH concentration was low. But total nitrogen content was shown the highest in the Cu 2000μM than other treatments and was increased as pH was low. Heavy metal accumulation of roots in two plants was higher than the content of shoot part. Heavy metal accumulation concentration was measured Cu 369.79μg/g, Cd 114.99μg/g in roots of cosmos, and Cu 318.94μg/g, Cd 81.20μg/g in roots of sunflower.

PFAPA (Periodic Fever, Aphthous stomatitis, Pharyngitis, and cervical Adenitis) syndrome has characteristic features of an early onset, periodicity (interval <4 weeks), and a brisk rising high fever (>39℃) of 3 to 6 days' duration without signs of infection. An 18-year-old male was admitted for high fever, sore throat, headache, and abdominal pain. He had suffered from periodic fevers associated with pharyngitis and cervical adenitis for 14 years without any evidence of infection. The fever recurred approximately every 4 weeks lasting 4 to 7 days with intervening asymptomatic periods. Physical examination was unremarkable except for slightly injected tonsils. Most laboratory tests including CBC were normal except for elevation of Creactive protein level (3.47 mg/dL). Bacteriologic and radiologic studies were negative. The fever was spontaneously subsided in 6 days. To our knowledge, this is the first case report of PFAPA syndrome in Korea. (Korean J Infect Dis 33:219∼222, 2001)

This research used cosmos(Cosmos bipinnatus Cav.) and sunflower(Helianthus annuus L.) to test the potential of phytoremediation. A advantage of phytoremediation is that it is a green technology and when properly implemented is both environmentally friendly and aesthetically pleasing to the public. I examined the growth rate and physiological quality and confirmed heavy metal accumulation of Cd and Cu-affected plants. Chlorophyll content was higher in the Cu treatment than the content of control, and was increased as Cu concentration was increased. Its content with 20 and 100 μM Cd treatment was reduced. Soluble protein content was shown no difference in the heavy metal treatment of low concentration in compared with the control, but its content was reduced in Cu 2000μM and Cd 100μM. Total nitrogen content was the lowest in two plants treated with Cu 2000μM and shown the tendency of reduction when their growth period passed unlike the tendency of chlorophyll and soluble protein. In the experiment of heavy metal accumulation, it was shown that the inhibition of growth rate and physiological responses were a little when its heavy metal concentration were increased, but increased the tendency metal concentration of tow plants during growing period. And the heavy metal accumulation concentration of root was investigated higher than shoot parts in two plants. Heavy metal accumulation concentration was measured Cu 453.44㎍/g, Cd 675.14㎍/g in roots of cosmos and it is Cu 353.14㎍/g, Cd 140.76㎍/g in roots of sunflower. Consequently we may be consider landscape materials which cosmos and sunflower has the potential as phytoremediator.

외상으로 실활된 미성숙 영구치에서의 계속된 치근 형성

강유진,김혜영,김영진,김현정,남순현 大韓小兒齒科學會 2009 大韓小兒齒科學會誌 Vol.36 No.4

치아에 외상을 받은 경우 치수 생활력의 상실은 흔한 일이다. 치수 생활력을 검사하는 방법으로는 임상적, 방사선학적으로 여러 가지가 있지만, 미성숙 외상치의 경우 일시적 현상과 가성 반응이 나타날 수 있으므로 치수 괴사에 대한 정확한 진단은 매우 어렵다. 생활력을 상실한 치아는 염증성 치근흡수, 치근단 낭종 등의 발생을 방지하기 위하여 치수 치료를 시행한다. 그러나 미성숙 영구치의 경우, 치수 치료를 시행 후 치근 성장이 정지될 수 있어 결과적으로 얇고 짧은 치근이 형성되어 장기적인 예후는 좋지 않다. 본 임상 증례에서는 외상으로 인하여 실활된 초기 영구치에서 치근단부의 최소한의 침습적 치근단 형성술로 계속된 치근 형성을 보여 이에 보고하는 바이다. In case of luxation injuries, loss of tooth vitality is common. And in case of trauma in the immature permanent teeth, precise diagnosis of pulp necrosis is very difficult. That is because limitation in distinguishing between normal dental papilla in immature permanent teeth, transient apical breakdown(TAB), which is part of normal healing process, and apical radiolucency in pulp necrosis. Especially in non-vital immature permanent tooth, the treatment is complex and requires long time. This clinical case report shows that severely infected immature teeth with periradicular periodontitis can undergo healing and apexogenesis or maturogenesis with no definative treatment or after conservative treatment. In the cases reported, we emphasize the considerable power of regeneration of the tooth, probably due to its large number of undifferentiated mesenchymal cells in the dental papilla, pulp tissue, periodontal ligament tissues. Thus, when endodontic treatment in immature permanent teeth, over instrumentation is not recommend for preserve the apical vital stem cells.
