The purpose of this study is to analyze and derive the significance of experience-oriented dance education inherent in John Dewey's education theory to find out how it relates to maker education, and to present the implementation plan of maker education for experience centered elementary dance education. The research method performed literature analysis (Creswell, J. W., 2011) in parallel with data collection based on the COSI model (Bidwell, S., & Jensen, M. F., 2004). As a re sult, interaction- communication is about empathy and collaboration, continuity- expression is a creative work idea and production, reflec tive thinking- is about spontaneity direct experience- utilization is advanced science, digital environment, convergence technology (art + technology, etc.), it was confirmed that indirect experience- judgment can have an educational functions of creative convergence through the contact element of sharing, three measures were proposed for the im plementation of maker education for experience-centered elementary dance education. It is believed that elementary dance education should be conducted in various forms of research and development that com bine maker education in terms of future education to foster creative fusion type talent.

Methimazole-Induced Bullous Systemic Lupus Erythematosus: A Case Report

서지연,Hee-Jin Byun,조광현,이은봉 대한의학회 2012 Journal of Korean medical science Vol.27 No.7

Bullous systemic lupus erythematosus (SLE) is a kind of LE-non-specific bullous skin disease that is rarely induced by a medication. We describe the first case of bullous SLE to develop after administration of methimazole. A 31-yr-old woman presented with generalized erythematous patches, multiple bullae, arthralgia, fever, conjunctivitis, and hemolytic anemia. Biopsy of her bulla showed linear deposition of lgG, lgA, C3, fibrinogen, and C1q at dermo-epidermal junction. She was diagnosed as bullous SLE and treated with prednisolone, dapsone, hydroxychloroquine, and methotrexate. Our experience suggests that SLE should be considered as a differential diagnosis when bullous skin lesions develop in patients being treated for hyperthyroidism.

서지연,김성순,김정상 한국식품영양과학회 2014 Preventive Nutrition and Food Science Vol.19 No.1

Excessive ethanol intake is known to induce a number of physiological symptoms, including headache, dizziness and vertigo. In this study, we investigated the attenuation effect of sprouted peanut extract (SPE) on ethanol-induced hangover in male Sprague-Dawley rats. The animals were divided into five groups: the control group, which was administered ethanol only; the ethanol plus SPE experimental groups, which were administered ethanol and 100, 200, or 400 mg SPE/kg b.w.; and the positive control group, which was administered ethanol plus DAWN808ⓡ, a commercial product. SPE-suspended water was delivered to rats via gavage 15 h and 30 min before the administration of ethanol. Blood was collected from the tail 0, 1, 3, and 5 h after ethanol administration. The results showed that serum ethanol concentrations were significantly lower in SPE treated groups than in the control group. Furthermore, hepatic alcohol and acetaldehyde dehydrogenase activities were enhanced by SPE in a dose dependent manner. These results suggest that SPE could be useful in attenuating hangover after alcohol consumption.

Comparison of Superparamagnetic Iron Oxide Labeling Efficiency between Poly-L-Lysine and Protamine Sulfate for Human Mesenchymal Stem Cells: Quantitative Analysis Using Multi-Echo T2* Magnetic Resonance Imaging

서지연,이정현,이창경,신지훈,최충곤,김정곤 대한영상의학회 2013 대한영상의학회지 Vol.68 No.2

Purpose: To quantify in vitro labeling efficiency of protamine sulfate (PS) and poly-L-lysine (PLL) for labeling of human mesenchymal stem cells (hMSCs) with superparamagnetic iron oxide (SPIO) using multi-echo T2* magnetic resonance (MR) imaging at 4.7 T. Materials and Methods: The hMSCs were incubated with SPIO-PS or SPIO-PLL complexes. Their effects on the cell metabolism and differentiation capability were evaluated, respectively. The decrease of iron concentrations in the labeled cells were assessed immediately, and at 4 d after labeling using multi-echo T2* MR imaging at 4.7 T. The results were compared with those of Prussian blue colorimetry. Results: The hMSCs were labeled more efficiently by SPIO-PLL than SPIO-PS without any significant effect on cell metabolism and differentiation capabilities. It was feasible to quantify the iron concentrations in SPIO-agarose-phantoms and in agarose mixture with the labeled cells from T2* maps obtained from multi-echo T2* MRI. However, the iron concentration of the labeled cells was significantly higher by T2*-maps than the results of Prussian blue colorimetry. Conclusion: The hMSCs can be effectively labeled with SPIO-PLL complexes more than with SPIO-PS without significant change in cell metabolism and differentiation. In vitro quantification of the iron concentrations of the labeled is feasible from multi-echo T2* MRI, but needs further investigation.

Bloody nipple discharge in an infant

서지연,김상정,이순주,송은송,우영종,최영륜 대한소아청소년과학회 2010 Clinical and Experimental Pediatrics (CEP) Vol.53 No.10

Although milky nipple discharge appears frequently in infants, bloody nipple discharge is a very rare finding. We experienced a 4-month-old,breast-fed infant who showed bilateral bloody nipple discharge with no signs of infection, engorgement, or hypertrophy. The infant’s hormonal examination and coagulation tests were normal, and an ultrasound examination revealed mammary duct ectasia. The symptoms resolved spontaneously within 6 weeks without any specific treatment, except that we advised the mother to refrain from taking herbal medicine. Since no such case has been previously reported in Korea, we present this case with a brief review of the literature.

Order Communication System과 연동된 Clinical Decision Supporting System의 효과 평가

서지연,이은재,이자균,조경희,함정연 한국병원약사회 2010 病院藥師會誌 Vol.27 No.2

Objectives :We evaluated the effectiveness of Clinical Decision Supporting System (CDSS) which Kangbuk Samsung Medical Center(KBSMC) has developed. Methods: The prescriptions for hospitalized patients during the study period were reviewed before and after the application of two typical CDSS programs interworking with Order Communication System(OCS). The effectiveness of programs which is not applicable to medicinal powder was evaluated by assessing the number of prescriptions of the alternative medicines, Lansoprazole Orally Disintegrating tablets(ODT) and Valproic acid syrup. In the case of the program assessing narcotic drug amount level, the number of prescription was checked for Pethidine 25mg at the specification of 50mg. For the study, the prescription review book of the year 2009 was investigated. Results: After applying the program, Valproic acid usage was increased 6.6 times in terms of the prescription amount: 14,238ml and 82,542ml of year 2006 and 2008, respectively, and 105,122ml at 2009(Annual average 14,238 ml vs 93,832 ml). Annual amount of Lansoprazole prescription increased 7 times after application of the program: 3,140 and 4,189 tablets for year 2008 and 2009, respectively, compared to 524 tablets for year 2006 when the program had not been applied(Annual average 3,664 tablets vs 524 tablets). The number of cases in which Pethidine 50mg was leftover after prescription has decreased after the program application in December 2009: 92 cases for Aug, 57 cases for Sep, 65 cases for Oct, and 71 cases for Nov in the year of 2009 compared to 48 and 9 cases for Dec 2009 and Jan 2010, respectively, with no occur from February to March(Monthly average 71 cases vs 14 cases). The analysis of 2009 prescription review book has shown that simple OCS operational mistakes were mainly found for outpatient prescriptions. In case of inpatient, however, many mistakes were caused by incomplete understanding of the hospital system and prescription drugs as well as the operational errors in OCS. Conclusion: The CDSS programs evaluated in this study were all effective. The prescription of medicines which is not applicable to medicinal powder and the remaining amount of narcotic drug occurred at reduced level. Drug-related CDSS is necessary for all medical institutions. However,the indiscriminate development of the program could drop clinician's acceptance rate and interfere with medical care. Therefore, the information provided must be clinically meaningful and should be constantly updated.
