        교원의 교원능력개발평가 결과, 인구학적 특성과 전문성 인식의 관계

        박지혜,이경란,문은주 이화여자대학교 교육과학연구소 2015 교육과학연구 Vol.46 No.4

        This study aimed to provide useful information by investigating the relationships between the results of teacher evaluation for professional development, teachers’ demographic characteristics, and their perception of expertise. Among those who participated in the survey asking teachers’ perception of the 2014 teacher evaluation for professional development, the data from 1,622 teachers in the upper and lower limits of one standard deviation of teacher peer evaluation and student satisfaction were used. Study findings were as follows. First, statistically significant and positive correlations existed between teacher evaluation results and teachers’perception of expertise. Second, female teachers, those whose career spanned 5-15 years, elementary teachers perceived their expertise higher than those of male teachers, those whose careers did not span 5-15 years, and middle and high school teachers. Third, mean scores of expertise perception of teachers who had high scores on peer evaluation and student satisfaction were higher than those of other groups. Last, providing information to parents and appropriate evaluation were the key factors distinguishing those who had high scores on teacher evaluation and student satisfaction from those had high scores on teacher evaluation and low scores on student satisfaction. In addition, providing information to parents was the key factor differentiating those who had high scores on teacher evaluation and student satisfaction from those who had low scores on both teacher evaluation and student satisfaction. The significance of these study results was discussed along with limitations and suggestions for future research studies.

      • 대학 배구선수들의 10일간의 Detraining이 식행동, 체력 및 혈중 지질농도에 미치는 영향

        김지현,조미란,조여원,선우섭,김희규 慶熙大學校 社會體育硏究所 1998 體育科學論叢 Vol.- No.11

        The purpose of this study was to investigate the effects of detraining for 10 days after season on food pattern, physique, physical fitness and serum lipid concentration to provide basic data for preparing an effective fitness control program for volleyball players in detraining period after season. The results were summarized as follows: 1. Total daily energy intake was increased by 10% owing to intake alcohol and so forth. In addition, triglyceride and very low density lipoprotein were increased because of disorder of food pattern. 2. Any physique factor did not changed except for skinfold thickness in subscapular. 3. The relative value of leg extension power was decreased of decine of strengh factor in power and leg extension time. Muscular endurance was significantly decreased , too. 4. Basal metabolic rate was significantly increased after season and diastolic blood pressure was decreased in rest. In conclusion, our results suggest that the detraining of volleyball players for 10 days after season affects serum lipids concentration, power and muscular endurance by disorder of food pattern. Therefore, for improvement of performance in new season, the leaders of sports should present more reasonable program of food pattern and personal voluntary training in detraining period.

      • 당뇨환자에서 비케톤성 고혈당에 동반하여 나타난 전신성 무도병 1예

        Even thoght the nonketotic hyperglycemia is a metabolic disorder, it complicates hemichorea-hemiballism rarely. Moreover, generalized chorea-ballism associated with nonketotic hyperglycemia in diabetes mellitus is very rare, so has not been reported in Korean literature. Although the precise pathophysiologic mechanisms of these disorders are still poorly understood, deficiency of gamma aminobutyric acid (GABA) in nonketotic hyperglycemia or reduced GABAnergic inhibition by striatal lesion may increase inhibitory output to subthalamic nucleus. These result loss of pallidal inhibition and produce contralateral hemichorea-hemiballism. The striatal lesions, such as transient ischemia with reactive astrocytosis or small amount of petechial hemorrhage, are related with changes of magnetic resonance image (MRI) findings presumably. We report a diabetic old woman who developed generalized chorea-ballismus as a very rare complication of nonketotic hyperglycemia. Her brain MRI showed high signal intensity in left lentiform nucleus and right pallidum on T1 weighted images and low signal intensity in bilateral putamen on T2 weighted images with highly enhanced corresponding lesions on T1 weighted enhancement images.

      • 가묘 유구치의 실험적 치수노출후 분지부 부관 부위의 치주조직 변화에 관한 연구

        김지영,양규호,최홍란 전남대학교 치과대학 1992 전남치대논문집 Vol.4 No.1

        The lesions that involve the furcation region of multirooted teeth may have an endodontic as well as a periodontal origin. Many authors have indicated the interrelationship of the pulp and the periodontium. The infection may be passed between the two through the apical and lateral or accessory canals. Infected deciduous molars display different roentgenographic findings from those of permanent molars. While pathologic changes are seen roentgenographically at the root apex of the permanent molar, the pathologic changes are evidenced by a radiolucent zone between the roots in the deciduous molar. In order to investigate the reasons for this interradicular rarefaction in the deciduous dentition, experimental pulpal exposures were made in the mesiobuccal pulp horn of mandibular second deciduous molars of the kittens with no. 1/2 round bur. The kittens were from 10 to 15 weeks of age and were divided into two groups, 10 experimental groups and 1 control group. The animals were sacrificed in the regular interval from 2 to 20 days after pulpal exposure. The specimens were observed by the light microscope and intraoral standard radiograph. The results were as follows : 1. Radiographically, normal interradicular periodontal membrane and inter-radicular bone were shown in control group. In the animal sacrificed after 20 days, a definite thickening of the interradicular rarefaction were observed. 2. Light-microscopically, operated teeth had accessory canals(75%) running from pulp chamber to the periodontium in the bifurcation region. 3. The pulpal changes of lower 2nd deciduous molar with accessory canal were followed by changes in the periodontium at the opening of accessory canal. These changes led to pathologic destruction of much of the pulp tissue together with inflammation of periodontium in the bifurcation. But pathologic changes was not seen at root canal and apex. 4. Pulpal inflammatory changes of lower 2nd deciduous molar without accessory canals were confined to the area beneath the exposure or to the coronal part of mesial root canal. 5. In the mandibular 1st and 2nd deciduous molars without pulpal exposure and 1st deciduous molars of experimental group, the pulp, periodontium in the bifurcation, and apical regions were normal. From the above results, it is suggested that accessory canals play a major role causing furcation lesion following experimental pulpal exposure in deciduous molar in kittens.

        The onions are considered to be a favorable functional beverage because they contain much sugar and various nutrients, and they are juicy vegetable. This study was performed to establish manufacturing of functional onion beverage, which was made by glucose oxidase. Glucose oxidase catalyzes oxidation of glucose and makes generation of gluconic acid. Optimum conditions were obtained when the glucose oxidase catalyzed reaction was carried out at temperature of 25℃, agitation rate of 450rpm and aeration rate of 4vvm.

        폐렴 구균(Streptococcus pneumoniae)에 의한 척수 경막외 농양 1예

        이지영,위유미,손경목,기현균,문치숙,오원섭,백경란,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

        폐렴구균은 보통 폐렴이나 뇌막염을 일으키는 균으로 척수 경막외 농양을 일으키는 경우는 매우 드물다. 본 저자들은 폐렴 구균에 의한 척수 경막 외 농양을 경험하여 보고하는 바이다. 과거 건강했던 36세 남자 환자로 사다리에서 낙상한 후 요통 및 고열, 신경학적 이상으로 내원하여 자기 공명 촬영 결과 척수 경막 외 농양으로 진단받고 항균제 투여와 함께 응급 수술을 시행하였다. 농 배양 결과 페니실린 감수성인 폐렴 구균이 분리 되었고, 수술 요법과 항생제 투여 후 농양은 치유되었으나 신경학적 이상은 호전 없는 상태로 타원으로 전원되었다. Pneumonia and meningitis are the most frequent manifestations of pneumococcal infections. Pneumococcal spinal epidural abscesses have been rarely reported. Spinal epidural abscess by Streptococcus pneumoniae has been diagnosed among the patients with diabetes mellitus, alcoholism, corticosteroid therapy, intravenous drug use, chronic renal failure, AIDS, and history of spinal surgery. Recently, we experienced a case of pneumococcal spinal epidural abscess after spinal trauma. A 36-year-old male patient was admitted with back pain, fever, and paraplegia which occurred 5 days after the trauma. Spine MRI revealed spinal epidural abscess at the level from T2 to T9. He was treated with antimicrobial agents and surgical exploration for spinal epidural abscess. Pus culture grew S. pneumoniae which was susceptible to penicillin. Despite early surgical treatment, neurologic sequelae remained. Considering the high mortality and morbidity of pneumococcal spinal epidural abscess, early diagnosis and aggressive treatment including surgical intervention and antibiotics therapy should be implemented immediately.
